This study investigated correction reports in Korean newspapers, both conservative newspapers and progressive newspapers, from 2008 to 2012 to urge a realistic alternative. Newspapers with the most correction reports were in the order of “Chosun Ilbo”, “ DongA Ilbo”, “Hankyoreh Shinmoon” and “Kyunghyang Shinmoon”. 25 statements of apology for misreport were made by conservative newspapers (11) and progressive newspapers (14). The number of statements of apology for misreport was in the case of Kyunghyang Shinmoon(4 times, 80%), Hankyoreh(twice, 22.2%), Chosun Ilbo(3 times, 60%), Dong-A Ilbo (3 times, 66.7%).

온라인 커뮤니티의 대안적 미디어로서의 가능성은 온라인이라는 플랫폼이 가진 개방성과 자율성과 같 은 매체기술적 요인 이외에도 다양한 커뮤니케이션 요소로부터 적지 않은 영향을 받는다. 이러한 다양한 요소들 가운데, 이 연구는 토론 주제가 가지는 속성이 온라인 커뮤니티의 대안성 발휘에 상당한 영향을 미 칠 수 있다고 보고, ‘개성공단 사태’라는 정보 접근의 제약이 크고, 대안적 의견과 주장의 다양성을 확보하 기 어려운 이른바 토론 난제에 대한 온라인 토론에서도 대안성이 발휘될 수 있는지를 검토해 보았다. 이를 위해, 연구는 ‘개성공단 사태’에 대한 온라인 커뮤니티(<다음 아고라>)가 종이신문의 보도 양상(양적 내용 분석)과 프레임(질적 내용분석)에 견주어 어떠한 구성적 다양성과 내용적 차별성을 보이는지를 분석했으 며, 그 결과는 크게 다음의 두 가지 차원으로 요약된다. 먼저, 종이신문의 보도 양상에 견주어, <다음아고 라> 토론은 과도한 ‘선정적 단어’ 사용, 부정적 인식 일색의 ‘미래 전망’, 그리고 ‘국내 전문가’ 중심의 제한 된 ‘정보원 활용’이라는 한계를 드러내고 있었다. 다음으로, 미디어 프레임에 있어 <다음 아고라>는 개성 공단 사태의 ‘배경 및 원인’과 ‘결과’ 프레임에서 종이신문과 일정한 유사성을 보이면서도, 종이신문에서는 드러나지 않았던 보다 다양한 프레임을 제공함으로써 그 내용적 다양성과 차별화를 보여주고 있었다. 특 히, 이와 같은 내용적 대안성은 사태의 ‘해결 방안’으로 ‘고립 전략’이라는 차별화된 프레임에서 두드러졌 는데, ‘대화유도’에 방점을 둔 종이신문과 큰 간극을 보여주었다. 결론적으로 이 연구는 온라인 커뮤니티 의 대안적 미디어로서의 역할과 기능이 토론 난제에서도 일정 부분 발휘될 수 있다는 것을 시사받을 수 있 었으며, 이로써 온라인 토론의 질적 수준을 어느 정도 긍정적으로 평가할 수 있었다

본 연구는 조영제를 사용하는 CT검사에서 조영제 부작용이 발생한 환자에 대한 정보를 수집하고 분석하여 조영제 부작용 발생인자들을 분석하여 조영제 부작용을 미리 예측하고 예방하여 조영제 부작용 발생빈도를 최소한으로 줄이고자 하며, 병원 내 약물부작용 관리 업무에 기초자료로 활용하여 병원의 진료 서비스의 향상과 영상의학과 종사자들의 업무 효율성을 증대시키고자 한다. 연구 대상은 대전광역시에 소재하는 4개의 종합병원에서 조 영제를 사용하는 CT 검사 중 만 18세 이상 남녀를 대상으로 2010년 1월부터 2014년 7월 까지 전산으로 기록되어진 4,932명 중 변수가 부족한 데이터를 제외하고 조영제 부작용이 발생한 환자 404명(이하 환자군)과 같은 기간 조영제 부작용이 발생되지 않은 환자에서 조영제 부작용이 발생한 환자의 성별, 조영제 종류를 교차하여 무작위 추출을 한 404명 (이하 대조군)을 대상으로 분석하였다. 기존에 알려진 위험 인자에 대해서 본 연구에서는 일반적 특성에 따른 조영제 부작용은 계절에 따른 특성에서 봄에 검사한 환자보다 겨울에 검사한 환자가 조영제 부작용 발생확률이 높게 나타나는 것으로 유의한 차이가 있었고, 다른 특성에서는 유의한 차이가 없었다. 조영제 부작용검사 관련 특성에서는 일반적인 검 사보다는 Dynamic 검사 시 조영제 부작용 발생확률이 높게 나타났고, 조영제 사용량이 130ml 이상 시, 주입속도가 4F/R 이상 시 조영제 부작용 발생확률이 높게 나타나는 것으 로 모든 특성들이 유의하게 차이가 나타남을 알 수 있었다. 계절적 변화에 따라 환자의 조영제 투입 시 세심한 주의가 필요하리라 생각되며, 매년 CT검사가 증가하고 있는 만큼 조영제 사용이 증가 할 것으로 예상되기 때문에 조영제 부작용의 일반적 특성뿐만 아니라 질병, 전처치, 심리적 요인, 기타 약물 복용, 등의 다양한 원인을 근거로 한 연구가 지속적 으로 진행되어야 하며 이러한 연구들을 통해 조영제 부작용의 발생 위험을 사전에 예방할 수 있는 체계적이고 효율적인 프로그램의 개발이 필요하리라 생각된다.

The aim of the present study was to compare two different serum-free media, modified synthetic oviduct fluid (mSOF) and modified potassium simplex optimization medium (mKSOM) containing 20% RD (RPMI1640 + DMEM, 1:1 v/v) (RD-mKSOM), for in vitro culture (IVC) of bovine embryos. After in vitro maturation and fertilization, the presumptive zygotes were cultured in two different serum-free conditions for 7 days and 9 days to evaluate blastocyst formation and hatching, respectively. Serum supplemented conventional CR2 medium was used as control. After 7 day of culture, there was no significant difference in cleavage and blastocyst formation rates among three groups (mSOF, 59.3 and 30.1%; RD-mKSOM, 65.0 and 41.5%; control, 51.6 and 38.0%, respectively). Hatching rate was significantly higher in control (69.0%) than other experimental groups (mSOF, 22.0%; RD-mKSOM, 39.5%) (P＜0.0001 and P＜0.001, respectively). Although both serum-free conditions showed lower hatching rates than serum-added control, in serum-free groups, RD-mKSOM showed significantly higher hatching rate than mSOF (P＜0.001). In addition, one-step using RD-mKSOM may facilitate IVC procedure than two-step culture system. In conclusion, the results indicate that one-step RD-mKSOM is more suitable defined culture system for IVC of bovine embryos than two-step mSOF.

Salmonellosis is one of the most common food-borne diseases in both humans and animals. The recovery of Salmonella from fecal and environmental samples by bacteriological assays takes several days. Polymerase chain reaction (PCR) has become an important technique for the rapid detection of Salmonella in a variety of samples, including feces. For rapid identification of Salmonella by PCR, 1 mL of enrichment culture was harvested after overnight incubation and DNA was extracted by heat lysis. To investigate the optimal conditions for rapid PCR detection of Salmonella, three different primer sets and three different enrichment media were used on a panel of Salmonella strains and a panel of non-Salmonella strains. The results showed that selenite cysteine enrichment broth and a primer set designed for the invA gene provided the most specific and rapid detection of Salmonella by PCR after the enrichment step.

The flow channel is a game design aspect that has been widely used by experienced game designers. A psychologist named Mihaly Csikszentmihalyi found that a person's skill and the difficulty of a task would interact to result in different cognitive and emotional states. When a person’s skill and the difficulty of the task are roughly balanced, he or she enters the flow state. Otherwise, the person becomes bored or frustrated, and switches to another activity[3]. Unfortunately, for game designers, this is the point where the flow theory stops helping. While a designer strive to keep players in the flow channel for as long as possible, he or she has to figure out how to implement the flow channel in the game by oneself. Therefore, in this paper, we tried to bridge or narrow the gap between game flow and psychology theories. We showed how the whole game flow mechanics work and how several major psychological elements operate dynamically and interactively on the game play. The challenges and skills should be balanced and should work together to create game flow experiences. The contents described in the paper was used to teach university students in game design and media psychology courses. Quantitative and qualitative measures show that our media psychology education could be an effective way of teaching a creative design philosophy.

The purpose of this study is to explore the effects of social media in Customer Relationship Management (CRM) based on a theoretical foundation. Social media was firstly used as a new communication tool by internet users, and is being commercialized as a powerful tool to build and maintain long-term relationships between customers and businesses. This study focuses on service sectors and aims to clarify how social media helps companies innovate traditional CRM. Social CRM is seen as one of these service innovations and is highlighted in this paper.

This research was conducted to undertake the impact of advertisements on multiple social media platforms on consumer responses. The study also researches internet and social media consumption habits of consumers of different demographics. The results largely suggest that positive consumer responses in form of better brand engagement, loyalty and recall are associated with organizations that indulge in promoting their products and services on multiple social media.

Social media users today have become active producers of information but how sharing brand-related information affects the attitude of other users is an important and unexplored path. Narayan et al. (2011) mentioned that User’s attitude towards the brand is shaped not just by the attributes of the products but also the preferences of other consumers, such as peers. Zhu et al. (2012), through their study concluded, user’s opinions significantly sway other user’s own choices or are likely to reverse their attitudes. Dawson et al. (1990) have supported that delivering experiences that are pleasurable and relevant will linger in the memory and influence the user’s attitudes and purchase intentions. Although previous studies researched the attitude of the users towards social media advertising, the effect of social media advertising on the user’s attitude towards the brand is yet to be examined. By applying the Uses & Gratification theory, stimulus-Organism-Response theory and the Theory of Reasoned Action, this study aims at evaluating the effects of information sharing, peer pressure, entertainment and emotional connection in a social media setting on the user’s attitude toward a brand present in social media thereby influencing their purchase intentions from the brand. An online survey was developed using items adopted from previous study and administered to college students, who are regular users of social media, such as Facebook, Twitter, and YouTube. Of 271 valid responses, 21% were males and 79% were females. Multiple regression analyses results supported all hypotheses. The results are consistent with the previous research, confirming user’s choice of media is influenced by their information seeking, entertainment and status needs (Tan, 198). Marketing via social media may offer content that have specific relevance or may offer entertainment for users (Chi, 2011) and may result in the establishment of an emotional connection with the brand. The more frequently brands interact with the users/fans/followers, the stronger will be the emotional connection which will affect the user’s purchase intentions from the brand. MaKenzie, Lutz & Belch (1986) in their study supported that the marketing patterns can influence the attitude of the users towards the brands which in turn affects the purchase intentions from the brand. The findings of this study confirmed that social media is a very important marketing tool. The marketers needs to ensure that they a) have a presence and social media, b) devise effective online marketing strategies and c) employ dedicated social media staff to continually interact, entertain and engage the users.

Purpose and Rational: Social media is an emerging platform for many retail communication channels accommodating various consumers’ needs and wants. There are many research exploring impact of social media on business practice and behavioral outcomes, however, there is only few research focusing on which factors affect the psychological and social variables on actual usage of social media for shopping. This study focuses on the role of consumer perception on flow of social media usage and the moderating effect of consumer’s social variables (i.e. social identity, group norm and social influence) on actual usage of social media information for shopping. The purposes of this study are as follow: 1) To examine empirical effects of flow of social media usage on perceived ease of use social media for shopping, perceived usefulness of social media information and actual usage of social media information for shopping. 2) To explore the perceived ease of use social media information for shopping and perceived usefulness of social media information affect actual usage of social media for shopping. 3) To investigate moderating effect of social variables between the links. Methodology: This research utilized an online self-administered survey to collect data. Two thousand e-mail invitations were distributed to a randomly selected sample from national panel and in order to address the hypotheses stated a dataset of 342 social media users was compiled. The instrument was designed to obtain comprehensive quantitative data and was an adaptation of questionnaire instruments validated in previous studies. For statistical analysis, the structural equation model was used. The results indicated that flow of social media usage influences on perceived ease of use social media information for shopping, perceived usefulness of social media information and actual usage of social media for shopping. Also consumers’ perceived ease of use on social media for shopping and perceived usefulness of social media information effect on actual usage of social media for shopping. Lastly, the social identity and social influence played as moderator variables between the links at actual usage of social media for shopping in all passages except group norm. The results empirically contribute to verify through quantitative research methods in relation to the role of flow of social media usage and the moderating effect of consumer’s social variables (i.e. social identity and social influence) on actual usage of social media for shopping.

Social media, Web 2.0 based social activity and powerful marketing tool, brought about a new paradigm for the 21st century culture and society. In line with the trend, the fashion industry is vigorously undertaking marketing activities on social media, seeking to build and maintain relationships with their customers through the Internet and mobile devices. The one-way provision of information by firms to customers has evolved to a symmetrical form of customers, whereby the customers also supply information to the firms share information with other customers. Through social media services, customers not only share their thoughts and experiences but also exchange tangible products and publicize the products, thereby directly participating in production and marketing activities of brands. Such participation of consumers offers inspirations for differentiated service on the part of the brands, for which proactive and long-term participatory activities of customers are required. Customer participation is of primary importance in current service marketing industry. Until now, related literature on customer participation has mostly centered on offline service situations. However, the advent of social media has simplified the process of participation for customers, and invoking voluntary customer participation has become the greatest challenge facing service industries, and, at the same time, the path to success. Those of us who live in the age of information technology are offered the opportunity to engage in two-way communication with other customers, the brand, and the media. Thus, customer participation is just as, if not, more important in an online environment. More and more customers are becoming directly involved in brand activities, which affect the brands as well as the customers themselves. Nonetheless, extant customer participation research focuses on developing constructs that are largely based on offline situations. Although such constructs correspond in part to the online setting, they fall short of meeting the unique characteristics of customer participation in social media. Therefore, in order to establish constructs for customer participation in social media, revision and supplementation of the offline-based constructs were found to be necessary. Based on interaction theory, this study explored the notion of customer participation in fashion brands’ social networking site (SNS) service by categorizing it into three types: customer-customer, customer-brand, and customer-media participation. In addition, it examined the external factors that influence customer social participation and how active social participation of customers in SNS affects trust and customer equity. The association between measurement variables according to the brand type was also closely examined. This study underwent two pre-tests to revise and supplement the survey items on customer social participation. A preliminary investigation was conducted on 516 respondents, and a total of 582 respondents participated in the main investigation. The respondents who were invited to participate lived in Korea, were in their 20s or 30s, and had previous experience in using fashion brands’ SNS service, SPSS 18.0 was used to conduct frequency analysis, exploratory factor analysis, reliability analysis, and t-test. Based on the results, AMOS 18.0 was used to undergo confirmatory factor analysis and structural equation modeling. The results of the study are summarized as follows. Based on the brand type (SPA and luxury) and the rate of sales, Uniqlo, a global SPA brand that boasts the largest number of SNS fans, and Louis Vuitton, a global luxury brand, were chosen for the study. The respondents consisted of consumers in their 20s and the 30s who, within the last six months, had previous experience in using the SNS service of the brands. The sample consisted of 40.7% male and 59.6% female, and 72.5% were in their 20s and 27.5% in 30s. A large percentage of the respondents were students (64.9%). The large proportion of university students reflects the trend of most active users of SNS being university students. Second, SNS service shopping context found positive association with customer-customer participation and customer-brand participation, but customer-media participation was insignificant. The results show that as the SNS is characterized by its linkage to different websites and platforms, customers are exposed to constant opportunities for participation. On the other hand, customer-media participation was found to be insignificant, which can be interpreted as indiscriminate constant supply of information that seeks to spur impulsive buying leading to antagonism of the customers. Such negative situations can be avoided by departing from indiscriminate provision of information to offering information that is customized to the needs and demands of each customer and invoking the customer to participate in information delivery. Third, SNS participation motivation and customer social participation were all positively associated. In particular, customer-media participation demonstrated the strongest influence, followed by customer-customer and customer-brand participation. As such, active participation of the customer with the brand is the most effective way to create collaborative, synergy effect or co-creation. Fourth, all routes from SNS user orientation to customer social participation were significant. SNS users in general possessed high levels of self-efficacy and tended to feel elevated as well as find altruistic pleasure in providing information that would help others. Such users participate through numerous ways such as customer-brand and customer-media participation but were the most active in customer-customer participation. Fifth, it was found that customer-customer and customer-brand participation builds trust of the customers toward the SNS service and the information or the information provider. However, customer-media participation did not indicate the same results. In order to build trust through participation, brands need to provide an inviting environment for customers to post comments and share information. Furthermore, marketing strategies, such as offering events and coupons to stimulate E-WOM activities of customers as well as creating a space for open communication are vital to building trust. Sixth, customer-media participation was positively associated with customer equity. Unlike customer-customer and customer-brand participation which requires constant physical effort of the customer, customer-media participation demands considerably less time and effort apart from the initial stages during which customization process is undergone to receive tailored information with just one click. Therefore, establishing convenient and practical system that targets the Y-generation in their 20s and 30s is emphasized in order to maintain a long-term relationship. Seventh, trust is positively associated with customer equity. Building trust is based on interactivity among people. This study found that customer-customer participation and customer-brand participation influence customer equity through trust, while customer-media participation leads to customer equity without being mediated by trust. Therefore, all three types of participation are equally important to customer equity. Eighth, brand type was a meaningful moderator to the relationship between SNS service shopping context, SNS service user orientation, participation motivation, customer social participation, trust, and customer equity. To summarize, the type of participation to encourage is based on the brand type, and as customers may have different expectations according to the brand, it is important to understand their orientations and provide customized information or an open space for communication. In addition, participation behavior has a strong potential to influence customer equity, but depending on the type of participation, trust may not necessarily positively influence customer equity. Therefore, it is recommended that brands offer credible and sincere information that customers can trust and follow. The significance of this study is that it is one of the first studies to examine customer participation in a social media environment. At a point in time where customers’ value creation is attracting increased attention, this study empirically revealed that customer-media relationship, which enables customer-customer and customer-brand participation on SNS, is also within the bounds of participation. Furthermore, this study identified the importance of relational marketing approach to brand and customer through customer social participation. By applying the concept of customer equity, which is in its fledgling stage in the area of consumer fashion marketing, it offers a basis for future research on long-term relationship building with firms The limitations of the study and suggestions for future research are discussed below. The sample of the study consisted of Koreans between the ages of 20 to 30. The limitation in the sample is inadequate to generalize the findings, and therefore, a comparative study with broader sample across culture and age is necessary. Moreover, this study observed customer participation on SNS environment. However, as there was a lack of preceding literature in this area, the measurement scales were revised and supplemented to fit the purpose of this study. The measurement instrument, therefore, needs to be further applied with different antecedents and consequences in subsequent research. Finally, due to the lack of previous literature on customer participation in SNS environment, the theoretical basis of the relationship between the variables lacked solidity. This study adapted a part of a theoretical framework to fit the context of the study to come up with the hypothesized relationship between the variables. Therefore, it is suggested that future research works toward developing and strengthening the theoretical framework of customer social participation.

This research is intended to provide marketing practitioners with an overview of web analytics to explore the issue of how to define and measure the effectiveness of social media through analyzing the various activities of current/potential consumers as well as provide a comprehensive analysis of the effectiveness of digital content marketing using social media. These analytics answer broad questions about which types of social media metrics are best at referring traffic, about conversations at the organization’s website, and about comparing different social media channels, such as Facebook and Twitter in this study. These analytics employ time series analysis to specifically address activities in SNSs that effectively drive traffic to a website and accomplish business goals. This study is one of the first empirical investigations in the marketing communication field related to measuring social media’s effectiveness. The major goal of this study is to demonstrate the value of businesses’ efforts and to optimize their digital/social marketing strategy using web analytics.

Launched in 2008 and 2010 respectively, Instagram and Pinterest are two of the fasted growing social media platforms with 220 million users combined (Leverage 2014, Techcrunch 2014, Loren & Swiderski 2012). Their success is due to their simplicity and a focus on visuals rather than text, furthermore they are described as platforms with strategic potential for fashion brands (Wired 2012). Despite this, many fashion brands have been slow to engage with them. However the Huffington Post (2012) suggests that the visual social media has a wide appeal with respect to both brand positioning and increasing awareness. Recent research by Mashable (2014) highlights that referral traffic and spend is higher from Pinterest users than Facebook users, and this contributes to the rationale for study. The aim of this reseach is twofold, firstly it is to explore the reasons for the utilisation of visual social media platforms within a fashion brands marketing planning cycle, and second it seeks to identify the strategic and operational ways in which fashion brands can use them. For the purpose of this paper only Instagram and Pinterest are investigated. Using a qualitative and inductive approach, the study will use in-depth elite interviews with 6 UK fashion brands (2 Luxury, 2 mid-market, 2 value) alongside content analysis of their platforms. This will enable the research to also consider how each platform can be harnessed at different levels of the market therefore contributing to the lack of empirical applied research in this area.

Introduction Driven by the rapidly evolving media landscape, firms extensively use social media to engage with their customers (Avery et al., 2010). Today, social media is an integral part of an individual’s daily life, which makes a vital venue through which companies connect with customers (Men & Tsai, 2011; Utz, 2009). Given the increased use of social media, recent studies have investigated how social media cultivates customer relationships with celebrities and/or media personalities (e.g., Smith, 2010). In light of the effectiveness of social media as a marketing tool, it is noteworthy to analyze the source power of celebrities and social relationships and consider how to take advantage of the power. The parasocial relationship is founded upon the communication process, which is an important factor in understanding the relationship between media and users. Parasocial relationships differ according to the motives for using social network service (SNS), while connection and attachment to celebrities, such as having empathy for a particular celebrity, is affected by celebrity source credibility. (Ohanian, 1990). The purpose of this study is to clarify the relation between parasocial relationships and customer equity in the social media context. The study investigates effects of motivations to use SNS and source credibility on parasocial relationships, as well as the effects of parasocial relationships on attitude and customer equity, and customer lifetime value. Theoretical Frameworks In this study, parasocial relationship refers to a virtual intimacy between a media personality and the media users, in other words, it is a psychological, interpersonal relationship unilaterally formed by users based on proximity, similarity, and attraction to the media personalities (Rubin & Step, 2000). When a parasocial relationship is formed, the media consumer appreciates the values and motives of the media character, often viewing him or her as a counselor, comforter, and model (Horton & Wohl, 1956). When using an SNS, users’ communication habits and their selection of social network services vary according to their motives, which in turn affect the parasocial relationships with celebrities via SNS. Motives for using SNS, specifically, information seeking, entertainment, and social connection may have a positive relationship with parasocial relationships. Source credibility, the positive characteristics of a communicator that affect the receiver’s acceptance of a message, positively influences parasocial relationships (Ohanian, 1990; McCracken, 1989) based on expertise, trustworthiness, and attractiveness of the media celebrities. In the social media context, a parasocial relationship has positive influence on attitude toward using an SNS. Social media users engage in finding people with whom they have an offline connection (Ellison, Steinfield, & Lampe, 2007). Social media enables individuals to connect with others all around the world easily, it is not surprising that parasocial relationships influence users’ attitude toward using social media, offering environments to enhance connections (Byod & Ellison, 2008). Further, it is worthwhile to note that parasocial relationships may have a positive influence on customer equity. The key to customer equity lies in understanding the customer lifetime value concept, which refers to the net present value of a customer’s profit stream (Rust, Lemon, & Zeithaml, 2004). Parasocial relationships positively influence brand, value and relationship equity, with the emergence of brands as one of the key organizational assets (Gummesson, 2004). Parasocial relationships explain relationships between individuals and brands, product, symbols, objects, and corporate identities. Such relationships allow individuals to have bonds with brands, trademarks and other symbols, politicians, sportsmen or even actors (Gummesson, 2004). Thus, they positively influence customer equity including brand equity, value equity, and relationship equity. Focused on effects of motivations to use SNS and source credibility on parasocial relationship as well as the effects of parasocial relationship on attitude, customer equity, and customer lifetime value, this study tests the following hypotheses: H1: Motivations to use SNS will have a positive influence on parasocial relationship. H2: Source credibility will have a positive influence on parasocial relationship. H3: Parasocial relationship will have a positive influence on attitude toward using SNS. H4: Attitude toward using SNS will have a positive influence on customer equity. H5: Parasocial relationship will have a positive influence on customer equity. Methods This study used a survey to investigate key questions about the associations between parasocial relationships and customer equity. A total of 350 social media users recruited from Hong Kong and Macau in China participated in the survey. Of the 350 participants, 129 were men (36.9%) and 221 were women (63.1%), with ages ranging from 21 and 35 years old (mean = 25.6 years). This study measured motivations for using SNS on a five-point Likert scale (1 = strongly disagree; 7 = strongly agree), which was adapted from an existing motivation scale (Leung, 2009; Leung & Wei, 1998; Sheldon 2008). To measure source credibility, this study used a five-point Likert scale, which was also adapted from an existing source credibility scale (Eisend & Langner, 2010; Priester & Petty 2003). Parasocial relationships were measured on the basis of user responses to 17 items on an existing five-point scale that assessed parasocial relationships (Koeppel et al., 1993). This study measured attitude toward using SNS through an existing scale (Venkatesh, Morris, Davis, & Davis, 2003). Customer equity was measured using an existing five-point scale (Keller, 2003; Rust et al., 2004) that elicited user responses to 13 items. Customer lifetime value (CLV) was calculated only for the customers in the sample, and CLVs were calculated separately before the average was taken by using the equation below: The CLVij of customer i to brand j, is given as: Tij= Frequency of purchases by customer i for a specific period of time dj= The rate of discount offered by company j fi= Annual average frequency of purchases by customer i for a certain period of time Vijt= The amount of purchase of brand j by customer i for a period of time t πijt= Expected profits by purchase unit of brand j by customer i for a period of time t Bijt= Probability that customer i buys brand j in purchase t Results The overall goodness-of-fit for this measurement model was acceptable (Chi-square = 8.218, df = 5, p = 0.145, GFI = 0.992, CFI = 0.991, RMR = 0.095, RMSEA = 0.043). The reliability coefficients of all 20 motivation measures were 0.885, and they were based on three factors of information seeking, entertainment, and building relationships. The reliability coefficients of all 16 source credibility measures were 0.924 with three factors of attractiveness, expertise, and trustworthiness. The reliability coefficients of all 17 parasocial relationship measures were 0.866 with three factors: proximity, similarity, and attachments. The reliability coefficients of all 13 customer equity measures were 0.838 with three factors of value equity, brand equity, and relationship equity. Cronbach’s alpha for attitude was 0.792. The coefficients indicate the acceptable reliability of the measures. Motivations to use SNS showed statistically positive effects on parasocial relationship (β = 0.151, p < 0.001). Specifically, entertainment (β = 0.148, p < 0.01) and building relationships (β = 0.093, p < 0.05) motivations showed significant positive effects on parasocial relationships while information seeking motivation did not show significant effects on parasocial relationships (β = 0.074). Source credibility showed statistically positive effects on parasocial relationship (β = 0.316, p < 0.001). Thus, the results supported H1 and H2. Parasocial relationships showed statistically positive effects on attitude (β = 0.295, p < 0.001) and customer equity (β = 0.272, p < 0.001). Attitude showed statistically positive effects on customer equity (β = 0.172, p < 0.001). Thus, the results supported H3 and H4. Customer equity showed statistically positive effects on customer lifetime value (β = 3.452, p < 0.001). Thus, the results supported H5 (see Table 1, Figure 1). Discussion This study contributes to clarifying parasocial relationships in the social media context and determining the relationships between parasocial relationship and customer equity. This study contributes to the theoretical foundation and implications of parasocial relationships and customer equity. Specifically, motivations to use SNS and source credibility positively influence parasocial relationship. Parasocial relationships have positive effects on attitude and customer equity. Customer equity, in turn, has positive effects on customer lifetime value. The study is the first of its kind on the effects of parasocial relationships on customer equity in the social media context. The study finds that motivations and source credibility are important antecedents of consumers’ parasocial relationships formed via social media. Parasocial relationships have a positive effect on attitude and customer equity, and customer equity leads to increased customer lifetime value. This study suggests that parasocial relationship is one of the strong influential variables on customer equity as it improves customer lifetime value. Thus, marketers should definitely consider parasocial relationship management in the social media context while tailoring their brand communications to their most profitable customers and enhance their customer lifetime value.

Driven by the consumer demand for companies to be socially responsible, companies are increasingly relating their brands to causes and charities in order to accomplish nonprofit objectives and corporate sustainability. In a social marketing campaign, the consumers’ choice of the cause can influence their reactions through the processes of choice. Allowing the consumers to choose the cause may also reinforce their personal role in the donation process, which may result in a better outcome. Further, advertisers are paying increasing attention to the launch of social marketing campaigns via social media, since social media has recently become an essential part of daily life and therefore an imperative venue through which companies connect with consumers. Focusing on the rapidly evolving social media landscape, this study primarily clarifies (1) how choice influences consumers’ perceived interactivity with a social marketing campaign in the social media context, and (2) consumer involvement, as consumers’ individual differences can enhance or limit the effects of a social marketing campaign with choice. Using field experiments, this study investigates the relationships between the consumers’ choice, perceived interactivity, attitude, and purchase intention, and considers the moderating effects of involvement on those relationships. This study’s contributions are that it illuminates (1) the effects of choice on the perceived interactivity of social marketing campaigns in social media contexts, (2) the role of involvement in social marketing campaigns as a moderator, and (3) attitude and purchase intention as outcomes that can facilitate the construction of a theoretical model for social marketing campaigns with choice in the social media context and offer possible implications for advertising practitioners.

The empirical study at hand explores the relationship between traditional and social media, and shows that media coverage and different forms of corporate communications do have an impact on social media chatter. Moreover online advertising is capable of taking advantage of awareness aroused by media coverage.

The main purpose of this study is to introduce and examine a multidimensional model of almost all relevant social media characteristics and their impact on brand perception and brand behavior. In order to incorporate social media’s high complexity we introduce our concept of SMURF and its related outcomes. Therefore we follow the original idea of Muniz and O’Guinn (2001) that define a brand community as a customer-customer-brand triad. Furthermore, we suggest an extension of their model that includes four dimensions covering all SMURF of a social media brand presence (SMBP), namely (1) customer-brand relation, (2) customer-customer relation, (3) customer-community relation and (4) customer-channel relation. For our defined core constituents of brand perception as well as for the essential elements of brand behavior already existing and tested reflective measures were used. Regarding the multidimensional construct of SMURF, the measurement instrument by Wiedmann, et al. (2013) was used. In detail, any SMURF core element was captured with one global item. Furthermore, any reflective and formative measures were specified to those brand and Facebook fan page which has been tracked most frequently by the respondent. The first contribution is to provide a multidimensional framework of value-based drivers of SMURF with special focus on an overall brand presence context. Second, the findings contribute to explain the consequences of social media attractiveness such as unique relevance features which provide a great brand appeal. In this study, customers who are strongly attracted to a brand fan page experience a high positive brand perception as well as a high positive brand behavior. Third, the empirical findings of the applied PLS-SEM approach indicate that customers have a specific motivation of being attracted and connected to a brand in a social media context.

Background and Purpose: The Ankle-Brachial Index (ABI) is the ratio of blood pressure in the lower legs to that in the arms. The intima-media thickness (IMT) of extracranial carotid arteries determined by B-mode ultrasound is a measurable index of the presence of atherosclerosis. A low ABI and a high carotid IMT are independently related to increased risk of cardiovascular events. This study examined the association between carotid IMT and ABI in patients with ischemic stroke. Materials and Methods: Retrospectively, 116 hospitalized patients with ischemic stroke were recruited. Using a pulse wave velocity ABI device along with carotid duplex sonography, we measured carotid IMT and ABI and investigated the correlation between average values. Results: There was a significant difference in carotid IMT between the normal and abnormal ABI groups (P=0.0262). The group with an abnormal ABI was more than five times as likely to have increased carotid IMT as the group with a normal ABI (age, sex-adjusted OR 5.67 (95% CI 1.85~17.38)). The ABI and carotid IMT showed a weak inverse linear correlation in patients with ischemic stroke (correlation coefficient −0.378 after adjusting for age and sex). Conclusion: Our study suggests that an abnormal ABI is associated with a high carotid IMT in patients with ischemic stroke.

루만에 의하면 현대사회에서 (의사)소통의 중요한 매체는 두 가지이다. 정보를 유포하는 매체와 일반화된 상징적 소통매체(또는 성공매체)가 그 것들이다. 이 논문에서는 정보유포 매체를 중심으로 재난의 위험과 세계 시민사회의 관계에 대해 살펴본다. 근대 시민사회의 발현을 가능하게 했 던 정보유포 매체는 활자매체라는 것이 일반적인 인식이다. 그러나 현대 사회에서 전자매체 특히 디지털매체의 사회구성적 효과에 대해서는 의견이 분분하다. 이 논문에서는 벡, 루만, 하이어의 관점을 비교하면서, 현대 사회에서 시민 주체의 형성과 관련하여 디지털매체의 중요성이 일방적으 로 강조되는 경향을 비판하고자 한다. 특히 세월호 참사와 관련하여 한국 사회에서 디지털매체뿐만 아니라 전자 대중매체의 역할이 새롭게 확인될 수 있음을 강조한다. 즉 언론통제 상황에서도 TV 전자매체가 전혀 의도하 지 못한 상태에서 불러일으키는 사회적 감정의 효과를 강조하고자 한다.

혼탁매질에서 형광, 산란과 응집의 영향은 파장과 산란된 형광세기로 나타내는데, laser induced fluorescence(LIF) 분광학에 의한 분자특성으로 나타난다. 산란매질에서 광학적 효과는 광학적 파라미터들(μs, μa, μt)에 의해 표현되고 응집은 고-액상 분리공정과 Photodynamic therapy에서 중요하게 활용되고 있다. 따라서 입자가 서로 접근될 때 콜로이드 입자들의 상호작용을 LIF와 응집효과로 분석하였다. 우리는 레이저 광원에서 검출기까지 농도의 함수에 의해 in vitro 시료의 산란과 형광 스펙트라를 측정하였다. 산란계수 μs는 산란체의 입자가 증가함에 크게 나타났다. 그리하여 Phorphyrin A 는 Phorphyrin C보다 산란세기는 증가하였으나, 침투깊이 δ는 감소하였다.
