The choice of strain, substrate, and environmental conditions are fundamental factors that determine the ability of a fungus to develop and produce mushrooms with high quality. The objective of this study was to compare the strains of Lentinula edodes and Ganoderma lucidum originated from South Korea and Brazil in relation to their vegetative development in different culture media, to obtain isolates with high quality. The strains of the two mushroom species from Brazil and South Korea grew slowly, possibly because of abiotic factors or storage technique used. However, it may be concluded that temperature, humidity, light, pH, and nutrients from the substrate, if not regulated appropriately may affect the vegetative species.

The objective of this study was to investigate the effects of a lettuce (Lactuca sativa L.) extract on the inflammation of human umbilical vein endothelial cell (HUVEC) and blood lipid improvement in hypercholesterolemic mice fed a high cholesterol diet. The lettuce extract (100% ethanol extract) inhibited the expression of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 in HUVEC treated with tumor necrosis factor-α (TNF-α). The lettuce extract suppressed the adhesion of THP-1 to TNF-α-treated HUVEC. The lettuce extract decreased the TNF-α-stimulated production of proinflammatory cytokine interleukin-6, interleukin-8 and chemokine monocyte chemotactic protein 1. In hypercholesterolemic mice, the lettuce extract reduced serum total cholesterol, triglyceride, and low-density lipoprotein-cholesterol level, while the lettuce extract elevated high-density lipoprotein-cholesterol level, resulting in the decrease of atherogenic index and cardiac risk factor level. These results suggested that lettuce extract can be an useful resource to show an anti-inflammatory effect and improve lipid metabolism

목 적 : 본 연구는 수술 전 양성 및 악성 간 병변 환자에 대하여 자유호흡기법(free breathing technique)을 사용하여 b-value (50, 500, 800, 1000)를 변환시켜 조영제 주입 전·후 현성확산계수가 어떤 수치적인 변화를 나타내는지 연구하고 악성 종양의 평가 자료로 유용한지 알아보고자 하였다. 대상 및 방법 : 본 연구는 후향적 연구로써 임상윤리위원회(institutional review board, IRB)의 승인(PNUHIRB-17)을 얻어 진행하였으며 연구 기간은 2015년 11월 01일부터 2016년 01월 30일까지 부산 소재 일개 P대학교 병원을 내원하여 수술전 간 MRI 검사를 의뢰 받은 환자 38명을 대상으로 하였다. 연구에 사용된 프로토콜(protocol)은 본원에서 시행되고 있는 간 검사에 최적화된 검사기법(TR:5100 ms, TE: 79 ms, SPAIR, NEX: 6, b-value type: 50, 500, 800, 1000)으로 조영제 주입 전 축삭면 확산강조영상을 자유호흡기법으로 영상을 획득하고 PRIMOVIST 10 ml (Gd-EOB-DTPA) 주입후 20분 지연기(hepatobilliary phase)에 동일하게 반복 시행하였다. 사용된 확산강조영상은 SE single-shot EPI (echo planar imaging)을 이용하여 b-value값을 50, 500, 800, 1000 s/mm2으로 세분화하여 검사를 하였다. 정량적 평가시 Image J와 work station을 사용하여 평가 하였으며 세분화 되어있는 b-value 값에 따라 ADC map을 나타내고, 이에 대하여 병변에 관심영역을 설정하여 현성확산계수를 구하였다. 통계적 분석은 대응표본 t-Test를 사용하였으며, p < 0.05 일때 통계적으로 유의하게 평가되었다. 결 과 : 간세포암의 경우 조영제 주입 전과 후의 현성확산계수의 수치는 pre ADC (500, 800, 1000: 1.238, 1.040, 1.007 × 10-3 s/mm2), post ADC (500, 800, 1000: 1.225, 1.094, 1.002 × 10-3 s/mm2)를 나타내었다(p>0.05). 간전이암의 경우 pre ADC (500, 800, 1000: 1.450, 1.472, 1.332 × 10-3 s/mm2), post ADC (500, 800, 1000: 1.438, 1.441, 1.354 × 10-3 s/mm2)를 나타냈고(p > 0.05), 혈관종의 경우 pre ADC (500, 800, 1000: 1.591, 1.365, 1.217 × 10-3 s/mm2)와 post ADC (500, 800, 1000: 1.906, 1.614, 1.396 × 10-3 s/mm2)는 변화 있는 결과를 나타내었다(p>0.05). 결 론 : 결론적으로 양성 종양의 경우 조영제 주입 전과 후의 결과의 연관성이 크지 않았고, 규칙성이 없었다. 하지만 간세포암의 악성병변(LR-5)의 경우 조영제 주입 후가 양성 병변에 비해 통계적으로 의미 있게 낮은 현성계수의 값을 보였으며, 정성적 분석에 향상을 가져왔다. 본 연구에서 제시한 바와 같이 복부 확산강조영상의 경우 질병과 검사 순서에 따라 현성확산계수의 결과 값과 확산강조영상의 명확도가 다르게 측정 될 수 있으므로 조영 전과 후의 확산강조영상을 병행한다면 좋을 것이라고 사료되며, 조영후의 현성확산계수와 이용 가능한 검사 시퀀스를 병행한다면 양성 및 악성 질환 감별의 진단에 효율성을 가져올 것이라고 판단되었다

This study examined the effectiveness of integrated language instruction using dictogloss on vocabulary knowledge and retention. Forty EFL students from two classes of an elementary school participated in the study. The integrated language class and segregated language class were examined by looking into the effect of each instructional type on the vocabulary knowledge development and retention. A total of 10 target words were selected from a storybook related to their textbook. Four types of vocabulary knowledge were measured: passive recognition, passive recall, active recognition, and active recall. The pretest and posttest were performed to measure the vocabulary growth. The retention rate of each instruction was examined by conducting a delayed posttest on the same words after two weeks. The results of this study indicate that integrated language instruction using dictogloss works better in vocabulary retention. They also suggest that further classroom research is required to prove that dictogloss is an effective way for vocabulary learning.

Spinnable pitches and carbon fibers were successfully prepared from petroleum or coal pyrolysis residues. After pyrolysis fuel oil (PFO), slurry oil, and coal tar were simply filtered to eliminate the solid impurities, the characteristics of the raw materials were evaluated by elemental analysis, 13C nuclear magnetic resonance spectrometer, matrix-assisted laser desorption/ionization time-of-flight mass spectrometer (MALDI-TOF-MS), and so on. Spinnable pitches were prepared for melt-spinning carbon fiber through a simple distillation under strong nitrogen flow, and further vacuum distillation to obtain a high softening point. Carbon fibers were produced from the above pitches by single-hole melt spinning and additional heat treatment, for oxidization and carbonization. Even though spinnable pitches and carbon fibers were processed under the same conditions, the melt-spinning and properties of the carbon fiber were different depending on the raw materials. A fine carbon fiber could not be prepared from slurry oil, and the different diameter carbon fibers were produced from the PFO and coal tar pitch. These results seem to be closely correlated with the initial characteristics of the raw materials, under this simple processing condition.

The counterfeit market makes up as much as seven percent of worldwide trade and is estimated as a $650 billion industry. Due to consumer demand, this phenomenon has grown over 10,000% in the past two decades and presents a serious threat to the global economy. Many luxury brand managers assume that counterfeiting damages brand image, however some experts have indicated that luxury houses use counterfeit sales to predict demand for their own brand. In this sense, brands are reacting to the effects of counterfeit purchase and need to develop a proactive strategy for preventing it. By understanding consumers’ perception of brands and how it relates to their counterfeit consumption, brand managers can better plan their marketing strategies to build relationships with consumers for increasing loyalty and preventing possible loss in sales. The purpose of this study is to understand the effect of branding on non-deceptive counterfeit consumption of luxury brands by proposing that brand equity plays a moderating role in the relationship between attitudes toward counterfeits and purchase intentions and in the relationship between social factors and purchase intentions. Specifically, this study conceptualizes the customer-based brand equity model with the Theory of Reasoned Action to develop strategic marketing implications for luxury brands. Previous research has resulted in managerial implications for combatting the counterfeit phenomenon, but it is more effective to prevent the increase in demand for counterfeits than to react to that demand. This study examines the role of brand equity to help brand managers focus their marketing strategies on specific levels of customer-based brand equity to build stronger relationships with consumers and reduce the demand for counterfeit products. Previous studies have examined the effects of counterfeits on brands, but research on the effects of brands on counterfeit consumption is very limited. This study adds to literature on counterfeits by understanding how branding can affect counterfeit purchase. Studies have used the Theory of Reasoned Action for understanding consumers’ intention to purchase counterfeit products. Drawing on the customer-based brand equity model, this research proposes brand identity, brand response, brand meaning, and brand relations as moderating variables in addition to the basic constructs of the model to extend previous literature, as no previous research has used customer-based brand equity for understanding counterfeit consumption. Previous studies have conceptualized customer-based brand equity for building relationships with customers, but this concept has never been used in the counterfeit context. This study is the first to use brand equity for understanding consumers’ counterfeit purchase intentions. This study suggests important implications for luxury brand marketers. By understanding how consumers associate with a brand, marketers can target specific levels of brand equity as part of their marketing strategies to deter counterfeit purchase. The proposed model serves as an initial step for understanding how brand equity affects non-deceptive consumption of counterfeit luxury goods. Future studies include empirically testing this proposed model and quantifying how much each level of customer-based brand equity contributes to consumer’ perception of brands. Future studies could also test the impact of branding on specific product types to analyze differences in consumers’ brand associations based on product category, as some product categories are more favorable to counterfeit consumers than others.

Due to the highly competitive nature of the apparel industry, fashion brands attempt to constantly engage consumers through various marketing strategies. Social media was found to drive female consumer purchases for apparel items. In shopping for fashion, consumers have used their personal connections on social media as an information source about different brands and products and to seek approval of their peers before making a purchase decision (Park & Cho, 2012). Cha (2009) found that female consumers look to their social media network connections for emotional connections, opinions, and approval on clothing, perfume, and accessories they are considering purchasing online. Ruane and Wilson (2013) found that female consumers use social media sites for information on where to shop and what merchandise to purchase. In studying the effect of blogs on corporate outcome, the role Millennials play is found to be significant. They are heavily reliant on word of mouth when up to 93% of Millennials has purchased a product after hearing about it from a family member or friend (Hoffmann, 2014). They not only usually read reviews prior to purchase, but also pass their recommendations via social media post-purchase (Hoffman, 2014). This age group constitutes 27% of the US population and in spite of their lower incomes, they spend more money on e-commerce than any other age group ($2,000 annually) (Smith, 2015). Therefore, this study aims to suggest strategies to fashion brands on effective blog campaign, which may eventually provide insights on how marketers can encourage engagement with female Millennial apparel consumers. The study’s objectives are 1) to examine the effect of brand awareness building customer’s brand credibility, brand similarity and blog engagement 2) to investigate the impact of brand responses on customer’s brand credibility, brand similarity and blog engagement, and 3) interaction effect between brand awareness and brand responses on customer engagement through cognitive evaluation in fashion blog context. A 3 (brand response: automated response, personalized response, no response) x2 (Brand awareness: well know, unknown) experimental design was developed through a pre-test of 139 participants. For main-test, experiment conditions and the following survey were completed by the convenience sample of 537 students in a large Southern university. Research findings revealed the significant impact of brand awareness on customer perceived brand credibility and brand similarity which were significant predictors of engagement intention. In contrast, the study indicated the insignificant relationship between brand responses and blog engagement intention. Study’s result not only suggested implications for marketers but also expanded further studies contributing on the body of knowledge.

While it was found that consumers’ experience on purchase intention is significantly affected by greater involvement in blogging (Hsu & Tsou, 2011), not many fashion companies use blogs to improve online consumption and relationship with their employee or customer (Fieseler & Fleck, 2013). Further, despite the growing significance of blog communication, there is a lack of understanding for the impact of accumulation of social capital in the blogosphere on the consumers’ attitude and engagement in previous research. This study is designed to address this gap, and particularly the role of three dimensions of social capital (i.e., structural, relational, and cognitive) in understanding blog user’s attitude and engagement. The purpose of this study is to investigate 1) the effect of blog user’s motivation (i.e., perceived usefulness, perceived ease of use, reputation, altruism, enjoyment, community identification) on their level of social capital within the blog 2) the influence of structural social capital and cognitive social on user’s relational social capital and 3) the impact of relational social capital on blog user’s attitude and engagement. Data was collected through a marketing research firm utilizing online survey method. With 530 usable data, the results of this study indicated enjoyment have positive significant effect on structural social capital while community identification have negative significant effect on structural social capital. For the effect of blogging motivation on cognitive social capital, the result showed positive significant effect of perceived usefulness, altruism and community identification on cognitive social capital Further, structural social capital does not have relationship with relational social capital while cognitive social capital has significant effect on relational social capital. The results also indicated that the relational social capital has influence on blogging attitude, which in turn has strong positive relationship with blogging engagement. The findings of this study contribute some useful knowledge about fashion blog and the relationships of the three social capital dimensions to the literature. Also, this study not only provides theoretical insight into understanding the influence of fashion blog user’s motivation on blogging behavior and satisfaction of needs of belong, it also exposes the influence of relationships building in blog community on user’s blogging attitude and engagement. Previous studies focused more on social influence on knowledge sharing motivation, and most of the researchers paid attention to the interaction of cognitive social capital and relational capital. This study employs the knowledge sharing motivation findings of previous studies, and it uses the effective motivation factors to test if they have the same impacts on people’s blogging behavior.

The purpose of this study is to develop a design as a high value-added exportable industrial product by developing a cultural product, that can be accepted as having universal beauty by people in the Western cultural area. This is done by, re-analyzing it from a modern perspective after applying the color representation, used in pop art, to Shin Saimdang’s Chochungdo (草蟲圖, insects on flowers) which clearly expresses Korea’s national emotion and aesthetic consciousness. The research method depends upon developing cultural products such as scarfs, neckties, handkerchiefs, and folding fans, which are communicated in the global market The expressive technique of pop art is utilized after reconstructing the color sensation of pop art in the aesthetic dimension of the natural, physical, and formative beauty of Chochungdo based on the whole understanding of our country’s genre of Chochungdo and Western pop art. With regard to the colors in the developed design, the basic colors were extracted and applied by selecting 10 pieces in the flower series, which were made with the silkscreen printmaking technique in the 1970s by Andy Warhol, a master in pop art. A work that integrates pop art, a global art trend, with Korean traditional culture is expected to highlight Korean traditional culture in the global cultural era.

Purpose: The aim of this study was to identify instructor’s experience on debriefing of nursing simulation education Methods: The participants were nine instructors in simulation-based nursing education. Data were collected from May, 2015 to June, 2015, through in-depth interviews and were analyzed on the basis of Colaizzi’s phenomenological methodology. Results: Three essential themes were extracts that were as follows 1) Instructors’ reflection on their teaching of debriefing in education 2) Determining the effects of debriefing in the simulation-based nursing education 3) Devoting one’s efforts for successful debriefing Conclusion: Debriefing is built on instructors’ reflection of how the debriefing process can be applied in simulation-based nursing education; this process can provide a practical understanding of nursing students, educational contents, and educational environments. Successful debriefing for enhanced nursing competency requires instructors’ effects to identify and deal with educational problems by reflecting on their teaching experience.

Purpose: The purpose of this study was to explore instructor's experience on nursing simulation education Methods: The participants in this study were 10 instructors at a university in Korea. They had teaching experience of simulation education in various parts of curriculum. Data were collected from October, 2014 to December, 2014, through in-depth interviews and were analyzed on the basis of Colaizzi’s phenomenological methodology. Results: Four essential themes were extracts that were as follows 1) Came across obstacles about use of the simulator 2) Need of instructors’ preparation for the simulation education is required 3) The simulation education conditions are in need of improvement 4) Need of efforts required to strengthen competency as professional nurses Conclusion: Even though at times the education was not carried out smoothly from simultor and education condition, the instructors felt the need for the simulation education in nursing and realized that instructors preparation and simulation education conditions were in need of improvement. Furthermore, the instructors thought the need of further efforts for the students to strengthen their nursing competency as professional nurses. Such understanding of the instructors’ experience, therefore, will be applied to the course of education, which will help maximize the effects of the simulation education and contribute to the necessary improvement required through the curriculum.

Cordyceps species (Cordycipitaceae, Hypocreales) were previously mentioned under dominant genera such as basidiomycetous Clavaria Vaill. ex L. and ascomycetous Sphaeria Haller. Cordyceps Fr. was coined by Fries (1818) from a combination of a Greek word cordyle, meaning a club, and a Latin word caput, meaning a head. Cordyceps was, however, ranked at tribal level under Sphaeria by Fries (1823). Link (1833) later re-elevated Cordyceps to genus level. As a result, there was variation on author citation of Cordyceps in different botanical codes such as Cordyceps (E. M. Fries) Link (1833), Cordyceps E. M. Fries (1818) and Cordyceps Fr. (1824). In 19th and 20th centuries, more and more species were described, with necessity to divide Cordyceps into subgenera, sections and subsections based on morphological similarities. Recent molecular phylogenetic studies, however, showed that Cordyceps is polyphyletic and its members are dispersed in various clades within Hypocreales. As a consequence, Cordyceps was amended in strict sense by Sung et al. (2007) and distantly related clades were named under separate genera. Here, we review recent nomenclatural changes of Cordyceps-related fungi in light of recent changes in the International Code of Nomenclature for algae, fungi, and plants (ICN).

The role of other customers play in determining a service customer's experience has emerged as important and received growing attention recently. Yet, the role of companions has not. In this study, using the healthcare setting as our research context, we explore how companions affect the patient throughout the service encounter process. Specifically, we propose that the quality of the role companions play affects the quality of the role patients play, which eventually affects the perceived quality of the service patients receive from the healthcare provider. In other words, we propose companions as a source of improving customer perceptions of service quality. Further, in an effort to define the desirable type of companions, we propose that the quality of relationship between the customer and the companion will influence the customer perception of the companion role quality. We also propose that the patient's stress level will moderate the effect of companion's role on the patient's role. In order to measure the quality of the role a companion and a patient play respectively, we first developed a scale for each by comprehensively compiling existing scales for each. We adopted the existing SERVQUAL items to measure perceived service quality. We adapted existing scales for measuring the quality of relationship between the patient and the companion and for measuring the patient's stress level. We plan to conduct a self-administered survey among the patients at a major university hospital in Seoul, Korea. We will analyze the collected data through a factor analysis, an analysis of variance, and a structural equation modeling approach. Findings of the current study will contribute academically by extending the research stream in viewing other human factors in the service setting as influential factor in determining the customer perception of service quality. Managerially, our study will contribute by demonstrating the importance of ensuring that companions play their role well throughout the service encounter process and also by presenting a comprehensive scale to measure the companion's role.

The influential role other customers play in forming a customer's service experience has gained growing academic and managerial attention recently. We intend to extend this stream of the research by proposing the effect of the interactions with other customers on the customer's quality perception of the service provided by the service firm. Through our findings we suggest that service firms should look beyond service personnel and consider other customers as a human factor influential on customer perceptions of service quality. Specifically, we propose that the perceived quality of C2C interactions indirectly affect customer perceptions of service quality through the mediation by the perceived social-emotional support. Using the selective halo effect theory, we theorize that the perceived quality of C2C interactions influence perceived quality of the assurance and empathy dimensions of SERVQUAL. We also suggest that the strength of the effect depends on customer role types. In order to fill the gap in the customer interaction research, which is mostly centered around experiential service settings, we choose a service setting in which functional benefits are more valued (i.e. healthcare services). Our study findings will help service managers become more aware of the importance of managing C2C interactions and learn specifically which aspects of C2C interactions to manage.

In this study, an electro-catalyst of Pt nanoparticles supported by polypyrrole-functionalized graphene (Pt/PPy-reduced graphene oxide [RGO]) is reported. The Pt nanoparticles are deposited on the PPy-RGO composite by chemical reduction of H2PtCl6 using NaBH4. The presence of graphene (RGO) caused higher activity. This might have been due to increased electro-chemically accessible surface areas, increased electronic conductivity, and easier charge-transfer at polymer-electrolyte interfaces, allowing higher dispersion and utilization of the deposited Pt nano-particles. Microstructure, morphology and crystallinity of the synthesized materials were investigated using X-ray diffraction and transmission electron microscopy. The results showed successful deposition of Pt nano-particles, with crystallite size of about 2.7 nm, on the PPy-RGO support film. Catalytic activity for methanol electro-oxidation in fuel cells was investigated using cyclic voltammetry. The fundamental electrochemical test results indicated that the electro-catalytic activity, for methanol oxidation, of the Pt/PPy-RGO combination was much better than for commercial catalyst.

방사선이 다양한 분야에 사용됨에 따라 방사선작업종사자의 수가 증가하고 있으며, 이에 따라 종사자의 안전에 대한 우려도 높아지고 있다. 국내에서는 KISOE 시스템, 발주자보고 등을 통해 종사자의 안전 확보에 주력하고 있다. 선행연구에서는 종사자 및 업체의 안전 확보를 위한 위험성 평가에 피폭선량과 더불어 이외의 항목에 대한 추가적 평가가 효과적일 것이라고 판단하여 평가를 위한 항목들 및 방사형 척도분석 모델을 개발하였다. 이에 본 연구에서는 2016년 방사선투과검사업체의 자료를 방사형척도분석 모델에 적용하여 실제 업체의 위험성 평가를 수행하였다. 또한 위험성이 낮을 것으로 예상되는 업체 2곳과 위험성이 높을 것으로 예상되는 업체 2곳을 선정하여 위험성 분석을 수행하였다. 분석 결과에서 예상과 동일한 결과를 얻어 모델의 타당성을 확인할 수 있었다. 전체 56개 업체의 위험성 평가가 수행되었고 업체별 문제점에 따른 개선 및 점검사항을 예측하였다. 본 연구 결과를 방사선투과검사업체 및 규제기관에서 자체 평가 및 규제 기준 등으로 활용할 수 있을 것으로 예상된다.
