정부는 대학 연구비 지원에 기반하여, 기술사업화 정책을 추진해 왔다. 본 논문 에서는 신제도주의 이론을 바탕으로 정부의 연구비 지원의 변화율이 기술사업화 성과의 변화율에 미치는 영향과 대학 소재지에 의한 조절효과를 분석하였다. 시간적 변화 분석에 통용 되는 잠재성장곡선모형(Latent Growth Curve Model, 이하 LGM)을 활용하여, 2009년～2017 년 9년 간 전국 4년제 138개 대학의 데이터를 분석하였다. 그 결과 정부지원 연구비의 증가 율은 기술이전 수입료 증가율에 정(+)의 영향을 미치며, 비수도권 대학보다 수도권 대학에 더 큰 영향을 미친다는 것을 확인하였다. 이러한 관계는 시간 지연효과를 고려한 분석에서도 동일하다는 것을 확인하였다. 이를 바탕으로 대학의 기술사업화를 촉진하기 위한 정부의 연구 비 지원 정책의 효과성에 대해서 대학의 소재지에 따라 차별적 이해가 필요함을 강조하였다.

본 연구는 286명의 사관생도들을 대상으로 종단적 연구를 통해 그릿이 다양한 성과 변수들에 미치는 영향을 탐색적으로 분석하였다. 핵심자기평가를 통제한 상태에서 그릿은 성과 변수에 유의미한 영향을 미치는 것으로 나타났다. 여러 시점에 성과 변수들을 측정한 결과, 그릿은 리더십 역량진단 점수, 주관적 성과, 생활태도 점수, 그리고 자기개발 점수에 긍정적 영향을 미치는 것으로 나타났다. 그릿의 두 가지 하위차원 중에서는 꾸준한 노력이 지속적 관심보다 더 강한 기준관련 타당도를 나타내었다. 특히 자기보고식으로 측정된 꾸준한 노력은 모든 측정시점의 리더십 역량진단 점수, 생활태도 점수, 자기개발 점수에 긍정적인 영향을 미치는 반면, 자기보고식으로 측정된 지속적 관심은 유의미한 영향을 미치지 않았다. 한편 일반학 성적에 대해서는 본인이 측정한 꾸준한 노력이 아무런 영향을 미치지 않았다. 또한 그릿을 자신이 평가했는지 타인이 평가했는지에 따라 그릿과 성과 변수들의 관계는 상이한 결과를 보여주었다. 연구결과를 바탕으로 시사점과 연구의 한계점 및 향후 연구방향이 논의 되었다.

본 연구는 기업의 고몰입HRM과 품질경쟁력, 제품수요, 매출액 변화율의 관계를 분석하였다. 연구의 초점은 세 가지이다. 첫째, 변수들의 변화율(slope)이 시간에 따라 유의하게 변화하는가. 둘째, 고몰입HRM과 각 변수의 변화율간의 인과관계는 종단적으로 유의한가. 셋째, 글로벌 금융위기를 기점으로 기업의 경영 관행과 성과요인들의 변화패턴은 유의하게 달라지는가에 대한 것이다. 분석을 위한 자료는 한국노동연구원이 2005년부터 2015년까지 조사한 사업체패널자료(WPS)를 이용하였다. 잠재성장모형을 활용한 분석 결과 고몰입HRM, 품질경쟁력, 제품수요, 매출액은 모두 시간에 따라 선형적으로 유의미하게 변화하였다는 것과 변수들의 변화율 간에도 유의한 효과성(고몰입HRM→품질경쟁력→제품수요→매출액)을 확인하였다. 그리고 글로벌 금융위기를 기점으로 1차-3차와 4차-6차 기간에 대한 분할함수 분석을 통해 금융위기 이후 기업들의 고몰입HRM과 경영성과 변수들의 변화기울기가 유의하게 낮아지는 것을 확인하였다.

조절하천의 낙동강에서 겪고 있는 부영양화와 조류 대발생 (유해남조의 녹조현상 및 담수적조)은 국내외적으로 가장 급속하게 확대되고 있는 수질문제이며, 다양한 집단에서 지대한 관심을 가지게 한 분야 중 하나이다. 본 연구는 2013년 1월부터 2017년 7월까지 낙동강의 8개 보 pools에서 주요 수질 환경요인을 주 간격으로 조사하였고, 우점조류와 상호 관련성을 비교 분석하였다. 연강수량은 2016년(보 평균 940.7 mm)에 많았고, 2015년 (672.8 mm)에 적었다. 장마·폭염기 (6~9월) 강우는 총강수량의 48.1%이었고, 상·하류간에 차이가 컸다. 총방류량 중 소수력발전, 월류 및 어도가 차지하는 비율은 각각 37.4%, 60.1%, 2.5%로서 홍수기를 제외하고 발전방류에 의한 비중이 매우 컸다. 방류량은 대부분 유입량에 비례하였으나, 취수량이 집중되는 보에서 다른 양상도 관찰되었다. 이것은 수위강하, 물 교환율과 연관되었고, 유해남조와 담수적조의 대발생에 심각한 영향을 초래하였다. 수온과 DO 농도의 변화는 기상·수문학적 영향이 지배적이었는데, 온도변화 뿐만 아니라 강우의 특성에 따라 변화 양상이 포착되었다. Chl-a의 평균농도 (최대값)는 SAJ~GAJ와 DAS~HAA구간에서 각각 17.6 mg m-3 (98.2 mg m-3), 29.6 mg m-3 (193.6 mg m-3)이었고, 하수의 영향이 절대적인 하류부에서 증가하는 경향이 현저하였다. 우점조류의 분류군 조성은 총 48속으로 규조 14속, 남조 8속, 녹조 18속 및 편모조 8속으로 각각 구성되었다. 유해 녹조현상과 담수적조의 주요 원인조류는 각각 남조 Microcystis와 규조 Stephanodiscus 개체군이었다.

본 연구는 국내 제약 산업을 대상으로 실패경험이 기업의 혁신활동에 미치는 영향을 연구개발, 지식탐색 측면에서 탐구하였다. 기존 연구들은 실패의 원인을 규명 하거나, 감소요건에 대한 고찰위주로 연구하였으나, 실패가 기업의 혁신활동에 미치는 영향을 분석한 연구는 드물다. 본 연구는 국내 제약 산업을 대상으로 10년간의 연구기간을 설정하여 실패가 혁신활동에 미치는 영향과 이러한 혁신활동이 급진적 혁신에 미치는 영향을 종단 분석하였다. 연구결과를 요약하자면 다음과 같다. 첫째, 기업의 실패경험은 탐험적 혁신활동을 촉진시키며, 이는 재무적 여유자본의 크기에 따라 차이를 보이는 것으로 나타났다. 둘째, 기업의 실패경험은 지식탐색 측면에서 유의하지 않은 것으로 나타났다. 셋째, 기업의 탐험적 혁신활동과 지식탐색범위의 상호작용은 급진적 혁신성과와 정(+)의 관계를 가지는 것으로 나타났다. 본 연구는 실패를 부정적 견해로 바라보던 기존의 연구와는 다르게 학습과 혁신에 긍정적인 영향을 검증하여 경험적 증거를 제시 하였다는 점에서 의미가 있으며, 이러한 연구결과를 기반으로 향후 연구의 발전방향을 제시하였다.

Introduction The concept of brand equity has been receiving considerable interest from academia and practice in the past decades. While mutual understanding exists on the importance of establishing high-equity brands, less agreement among academics and practitioners prevails regarding its conceptualization and operationalization. Many approaches have been proposed to measure brand equity in academic literature and numerous competing companies such as Millward Brown, Interbrand, or Young & Rubicam offer commercial metrics and brand evaluations, which are likely to estimate different values to a specific brand. This study reflects a consumer-based perspective on brand equity, which resides in the heart and mind of the consumer and captures the value a brand endows beyond the attributes and benefits its products imply. Growing calls for the accountability of marketing has resulted in increasing interest in marketing metrics, which includes mind-set metrics to address the “black box” between marketing actions and consumer actions in the market. Theoretical Development One of the most prominent conceptualizations of brand equity is based on the premise that brand equity is “the differential effect of brand knowledge on consumer response to the marketing of the brand” consisting of brand awareness and brand image as the predominant dimensions that shape brand knowledge. In this model, a crucial role is ascribed to consumer’s associations with a brand as a reflection of its image. Accordingly, brand building and differentiation is based on establishing favorable, strong, and unique associations. Human associative network theory is a widely accepted concept to explain the storage and retrieval of information and has been largely applied in the context of brands. Associative network theory suggests that brand information is stored in long-term memory in a network of nodes that are linked to brand associations such as attributes, claims or evaluations. Consumers use brand names as cues to retrieve associations. Once cues activate corresponding nodes and consumers retrieve information from memory, the activation spreads to related nodes. Consequently, a transfer of associations can also occur through associative chains in a process of attitude formation. Consumer response to a brand can be of attitudinal and behavioral character and research on attitudes supports the general notion that both, affective and cognitive structures, explain attitude formation. The predictive properties of attitudes regarding actual behavior have been acknowledged by prior research and the attitude-behavior relationship has been established. Research Design Operationalization of Brand Equity This study distinguishes between attitudinal and behavioral measures of brand equity. The behavioral measures of brand equity should reflect the attitudinal brand equity components in predicting product-market outcomes. High brand equity should lead to a willingness to pay a price premium, purchase intention and willingness to recommend. Survey Brand equity measures are tested with two waves of data collection2 from online surveys conducted in 2015 and 2016. Respondents were recruited from a professional panel provider to ensure that the same respondents participated in wave two after a year from the first wave. Participants were selected according to a quota regarding age and gender to increase representativeness and were then randomly assigned to one of the three industries beer, insurance, and white goods capturing brand equity from different perspectives and allowing for a more holistic view. Sample The sample for the first wave consists of 2.798 respondents. The sample was matched with the response from wave two and only those respondents were selected who participated in both waves. Given the panel mortality rate, the final sample size for longitudinal analysis is 1.292 observations. The respondents’ age ranges from 18 to 74 with 52 percent being male and 48 percent female. Analysis Panel regression is used to estimate models assessing the relative importance of various brand equity metrics regarding the three outcome variables for the three categories included. The results suggest that no universal brand equity metric dominates that can be applied to predict behavioral outcomes across categories. Yet, category-specific brand equity metrics prevail across outcomes. Consumers seem to evaluate a strong brand as an entity they can personally connect to in the insurance category. In the beer category, consumers’ evaluation of strong brands reflects deep affect and the perception of product quality. High equity brands relate to loyal consumers with strong affective evaluations in the category of durable household products. Moreover, the results indicate that brand equity measurement can be simplified to a small subset of metrics without risking loss of model fit and predictive power. Discussion While a plethora of brand equity metrics exists, the results of this study suggest that brand managers can apply a small subset of available metrics to track their brands’ equity and predict behavior without implementing long surveys that require considerable time and effort from increasingly overloaded consumers. Yet, adjustments to the composition of brand equity metrics might be inevitable in light of category-specific effects. Moreover, the results reveal that a consideration of metrics capturing affective components such as brand self-connection and deep feelings such as brand love is indispensable for brand equity measurement. Including emotional measures and extending established brand equity metrics that are deeply rooted in extant research might provide a considerable advantage when it comes to measuring brand value in different product categories.

The paper presents the longitude study of Internet technologies introduction into business model. Rapid spread of Internet technologies has a significant impact on the business models transformation. Today, information technology has become an integral part of communication with customers. In 2017 the penetration rate of the Internet in Russia reached 73%. Thus, almost 3/4 of the population is currently Internet users and be reached online. On the one hand, Internet communication speeds up and simplifies the processes; on the other hand, the key competitive advantage of direct selling business model is blurred. For ages business model was based on direct interpersonal contacts between the distributor and the customer. In this business model relationship creates more value than the product itself [Luk, Fullgrabe, Yi, 1996] and face-to-face meeting is the key descriptor [Sanan, 1997]. Direct selling is cultivated through relationships and provides customer-centric marketing opportunities [Harrison, Hair, 2017]. The question of this study is whether introduction of innovative Internet technologies into communication with customers is beneficial for traditional direct selling business model. Empirical research is based on comparative analysis of data from three survey waves (6380 respondents in 2011, 5638 respondents in 2014 and 6800 respondents in 2017). Effectiveness of Internet usage the for communicate with customers was analized in dynamics over the three waves of 2011, 2014, 2017. Using the one-way analysis of variance (ANOVA) method 15 (fifteen) hypotheses were checked. Nine (9) out of 15 (fifteen) hypotheses were confirmed. Research revealed that personalization determines the effectiveness of communication with customers via internet-based tools (e-mail, web site, social networks, professional social networks, video channels, blogs, microblogs, videoconferences and webinars, messaging applications and files). Nevertheless, face-to-face communication remains significant communication channel for success in direct-selling

Since more and more consumers rely on online consumer reviews in their purchase decision making, we have observed the emergence of empirical studies on online reviews in different contexts. Such studies look at various dimensions surrounding online reviews; nevertheless, none of them actually gives a more comprehensive picture as to the rating differences across online rating platforms and/or across time, let alone explains such differences. This study aims to address these understudied but managerially relevant issues. In our empirical study, we focus on hotel ratings across platforms and across time (i.e., across identified change point in time), and explain such differences by review text associating with the ratings. We investigated San Francisco hotels that were rated on both Tripadvisor and Expedia, and utilized the General Inquirer dictionary to identify the categories of words in a review. Regressions analyses were then conducted for the explanation of rating differences. We found that rating differences, in both the cross-platform and the longitudinal cases, are substantially associated with the number of words (in a negative relationship). Furthermore, word tags identified from the review text associated with ratings also explain the rating differences. To conclude, the research reveals that for a specific service provider, online ratings may vary significantly in both the cross-platform and the longitudinal senses. It demonstrates that adopting a systematic approach and utilizing an established semantic dictionary, information extracted from review text can substantially explain such differences.

This paper presents the findings of a survey of Turkish marketing academics undertaken between 2007 and 2016. As a follow up, replicating Erdoğan and Uzkurt’s study (2007), this study aims to accommodate the existing studies approaching the status and problems of marketing academics and add a longitudinal dimension in 2016.

This research was conducted to examine repeat online grocery shoppers behavior based on the S-O-R paradigm (Mehrabian and Russell, 1974) for a five year time frame. Not considering any artificial intelligence, generally in the online shopping environment, the image of the store is communicated through their product and site offerings as well as their user-friendliness of the website. Childers et al. (2001) discussed hedonic aspects of an online store environment such as web atmospherics. Furthermore, with a growing importance of atmospheric cues, researchers are now paying attention to consumer characteristics (Moriuchi and Takahashi, 2018). In general, the results show that atmospherics has an impact on pleasure and satisfaction. Both pleasure and satisfaction have an effect on loyalty. Trust served as a moderator between O-R and was significant. Comparing between the 2012 and 2016 data, results show that satisfaction consumers in the 2012 sample did not see an impact on satisfaction on loyalty, and trust was not a moderating factor on satisfaction and loyalty. However, all the other hypothesized relationships were significant for the 2016 sample. The results suggest a couple of practical implications. First, the ease of navigation are important in pleasing and satisfying online grocery shoppers. Marketing practitioners should focus on how to make the overall website easily navigable. This could include having clear display of the products, reviewing of product descriptions and ease of going back to the main menu after adding items to cart. Second, marketing practitioners should focus their attention on the variety of products available and the quality of products available such as pleasure.

As a surface treatment method of concrete pavement in Korea, transverse tinning has initially been applied to improve drainage and friction at first. Since 2003, in order to reduce the noise of concrete pavement, longitudinal tinning have been studied and proved its superiority. Therefore, Korea Expressway Corporation (KEC) has applied this as surface texturing method in concrete pavement from 2008 to the present. However, the lateral vibration during vehicle running has been continuously raised in the longitudinal tinning section, and lots of efforts have been made to solve this problem. Nonetheless, complaints still occur intermittently in some sections. In this research, three sections in which complaints occur and three test sections were chosen to evaluate characteristics of lateral vibration between tire and longitudinal texturing. Based on the literature survey on the correlation between longitudinal texturing and tire, evaluation of the site and FEM analysis of each road surface were carried out. As a result of the analysis, the lateral vibration occurred most frequently in the random tinning section compared to other sections, and it was relatively few at the other improved tinning of the test section. Further studies on various tire types and timing intervals in the future will provide a standard of longitudinal texturing, which will reduce lateral vibration.

목적: 안질환과 시기능에 이상이 없는 굴절이상 중 근시 어린이의 안경렌즈 교체주기에 따른 근시도 변 화를 관찰하여, 근시변화에 대한 적절한 조치를 취하기 위한 기초자료를 제시하고자 한다. 방법: 연구방법으로 대구광역시 소재 한 안경원의 고객 중 2013년 1월에서 2015년 12월 사이에 방문한 7 세에서 11세 사이(9.05±1.24) 안질환이 없는 근시안 291명(남 172명, 여 119명)을 대상으로 총 582안의 등 가구면 도수의 변화를 관찰하였다. 결과: 총 291명 중 1년 동안 관찰했던 사람은 291명이며 교체주기는 1~2회였고, 2년 동안 관찰했던 사람 은 193명이며 교체주기는 1~4회였으며, 3년 동안 관찰했던 사람은 106명이며 교체주기는 2~5회였다. 1년 간 등가구면 도수의 변화는 1회 OD : -058±0.35 D, OS : -0.56±0.38 D, 2회 OD : -0.94±0.61 D, OS : -0.87±0.56 D이었다. 2년간 등가구면 도수의 변화는 1회 OD : -0.58±0.30 D, OS : -0.58±0.30 D, 2 회 교체 시 –1.14±0.48 D, 3회 교체 시 –1.34±0.60 D, 4회 교체 시 –2.04±1.16 D 이었다. 3년간 등가구면 도수의 변화는 2회 OD : –1.32±0.58 D, OS : –1.45±0.39 D, 3회 OD : –1.68±0.59 D, OS : –1.59± 0.46 D, 4회 OD : –1.99±0.82 D, OS : –1.93±0.64 D, 5회 OD : –2.34±0.66 D, OS : –2.27±0.72 D이었다. 나이별 등가구면 도수의 변화량을 보면 7세에서 –0.71±0.78 D, 8세 –0.70±0.53 D, 9세 –0.60±0.66 D, 10 세 –0.55±0.60 D, 11세 –0.47±0.46 D로 나이가 올라가면서 도수의 변화는 줄어들었다. 결론: 근시 어린이의 안경렌즈의 교체 주기가 짧을수록 등가구면의 도수의 변화는 많았다. 나이별 등가구면 도수의 변화량은 나이가 올라갈수록 도수의 변화량은 줄어들었다. 근시의 완전 교정으로 인해 근거리 작업 시 저 교정 상태의 안경보다 더 많은 조절력이 요구되고, 그로 인해 근시가 더욱 빠르게 진행된다고 사료된다. 근시의 저 교정은 근시의 진행을 완화시키지만, 입체시의 저하, 시자극의 결핍으로 약 시의 원인이 될 수 있고, 양측 시각장애의 원인이 될 수 있다. 또한 독서 속도, 집중의 기능을 저하시킬 수 있다. 약시의 원인을 제거하고 독서 속도와 집중 기능의 향상을 위해서 충분한 교정시력이 나오는 원거리 안 경과, 작업거리에 따른 근거리 안경을 따로 사용하는 것을 권장한다.

Background: The MLA is supported by both the abductor hallucis (ABH) and the extrinsic muscles. Insufficient muscular support may lower the MLA when the body’s weight is applied to the foot. The short foot exercise (SFE) is effective in increasing the height of the MLA for people with flat feet. Most of the research related to the SFE has simply evaluated the efficiency of the exercise using enhanced ABH electromyography (EMG) activation. Since the tibialis anterior (TA), peroneus longus (PER), and ABH are all involved in supporting the MLA, a new experiment design examining the EMG of the selected muscles during SFE should be applied to clarify its effect. Objects: Therefore, this study aimed to clarify the effect of the SFE in different ankle position on the MLA angle and the activation of both the intrinsic and extrinsic muscles and to determine the optimal position. Methods: 20 healthy subjects and 12 subjects with flat feet were recruited from Yonsei University. The surface EMG and camera were used to collect muscle activation amplitude of TA, PER, and ABH and to capture the image of MLA angle during SFE. The subjects performed the SFE while sitting in three different ankle positions—neutral (N), dorsiflexion (DF) at 30 degrees, and plantar flexion (PF) at 30 degrees. Results: ABH EMG amplitudes were significantly greater in N and DF than in PF (p<.05). Muscle activation ratio of TA to ABH was the lowest in PF (p<.05). MLA angle in both groups significantly decreased in PF (p<.01). The TA and ABH was activated at the highest level in DF. However, in PF, subjects significantly activated the ABH and PER with relatively low activation of TA. Conclusion: Therefore, researchers need to discuss which SFE condition most effectively use the arch support muscle for flat foot.

All structures can not be perfect due to geometric or material initial imperfections. Initial imperfections are an important factor in determining the buckling mode and are known to be important factors in evaluating the actual buckling strength. The DNV-RP-C202 design standard limits the longitudinal stiffener spacing. However, the criteria for the stiffener spacing presented in DNV-RP-C202 is a guideline derived from the curved panel theory of perfect cross-sectional shape without initial imperfections. In this study, considering geometric initial imperfections, the transition point of stiffener spacing where longitudinal stiffeners affect the buckling strength of reinforced steel wind turbine tower is analyzed using finite element analysis program. The results of finite element analysis compared with theoretical results based on the perfect shape. As a result, a more reasonable stiffener spacing considering the initial imperfections was suggested.

Background: Short foot exercise (SFex) is often prescribed and performed in the sport and rehabilitation fields to strengthen intrinsic foot muscles. However, SFex is difficult to perform because of lack of feedback methods. Objects: The aim of this study was to compare the effects of SFex with and without electromyography (EMG) biofeedback on the medial longitudinal arch (MLA) of healthy individuals who maintained a static standing position. Methods: All participants (14 males and 12 females) were randomly divided into two groups (biofeedback and non-biofeedback groups). The EMG activity of the abductor hallucis (AbdH) and tibialis anterior (TA) and the MLA angle on the dominant leg side were measured with the participant in the standing position in the pre- and post-intervention conditions. The intervention session consisted of 15 minutes of SFex with (biofeedback group) or without (non-biofeedback group) EMG biofeedback. The groups were compared using two-way repeated measures analysis of variance. Results: The post-intervention activities of the AbdH muscle (p<.05) and the AbdH/TA ratio (p<.05) were significantly greater in the biofeedback group than in the non-biofeedback group. The activity of the TA (p<.05) and the MLA angle (p<.05) in the biofeedback group were significantly lower in the post-intervention condition than in the pre-intervention condition. Conclusion: The present findings demonstrate that the combination of SFex and EMG biofeedback can effectively facilitate the muscle activity of the AbdH and strengthen the medial longitudinal arch.
