This study is designed to examine the effects of information source's social distance on message attitude and online word-of-mouth intention (e-WOM). It also examined the moderation effects of blatant persuasive intention of message, the normative interpersonal influences, and the informative interpersonal influences on the relationship between social distance and advertising effectiveness. This study employed an experiment: 2(far/near social distance far/near) ${\times}2$(high/low blatant persuasive intention of message) ${\times}$(high/low normative interpersonal influences) ${\times}2$(high/low informative interpersonal influences). The results of this study are as follows. First, closer social distance led to more positive message attitude and higher online word-of-mouth intention. Second, when blatant persuasive intention of message is low, the effects of social distance on message attitude and WOM intention were more noticeable while those effects were less significant for high blatant persuasive intention of message. Third, there were no interaction effects of social distance and normative interpersonal influences on advertising effectiveness. Fourth, the effects of social distance on message attitude and WOM intention were more significant for high informative interpersonal influences than for low informative interpersonal influences. Implications of study findings are provided for strategic use of corporate Facebook page to generate positive consumer responses.

As the reduction of information exposure threats by organization insiders contributes to achieving information security(IS) goals, organizations are establishing strict IS policies applicable to insiders and increasing investment in IS systems. However, since IS incidents cause damage to an organization even by malicious information exposure by one person, psychological support for strengthening IS compliance behavior by insiders. This study aims to confirm how the uncertain organizational environment related to IS affects individual IS-related behavior. We surveyed insiders of organizations operating IS policies and tested the hypothesis using 440 samples. As a result, IS technology and communication uncertainty reduced IS voice behavior through IS prospective anxiety, and individuals' susceptibility to information influence moderated the relationship between IS technology, communication, and prospective anxiety and IS voice behavior. Our results suggest the necessity and direction of supplementing the uncertain IS environment in practice.

As protecting organizations' information assets affects their substantiality, they are increasing their investments in policies, regulations, and technologies for systematic information asset management and protection. This study confirms the impact on information security(IS) compliance from the perspective of employees who apply IS policies to actual work. In particular, this study identifies mechanisms linked to IS policy awareness, sanction, justice, and IS compliance from the perspective of expanding deterrence theory. We applied 316 samples obtained from workers of organizations that applied IS policies and regulations to work and verified the relationship between mechanisms by using AMOS and SPSS packages. As a result of the verification, IS policy awareness had a positive effect on organization justice and compliance intention through the severity and clarity of sanctions. Individual justice sensitivity had a moderating effect on the cause and outcome of justice. The sanction-related mechanism presented in this study provides strategic implications for organizations that require active IS activities by insiders.

허프 변환(Hough transform)은 영상에서 몇 개의 파라미터로 표현되는 기하학적 요소 추출을 위해 널리 사용되고 있는 방법 중 하나이다. 하지만 허프 변환은 영상의 한 픽셀이 허프 공간(Hough space)의 한 방정식에 대응되는 일대다 특성으로 인해 잡음에 민감한 특성을 갖는다. 이러한 잡음 민감성은 검출되는 직선의 개수뿐만이 아니라 검출된 직선의 품질에도 영향을 미칠 수 있다. 즉, 실제 직선에서 벗어난 직선이 검출되거나 하나의 실제 직선에 대해 여러 개의 직선이 검출되는 등의 직선 왜곡이 발생할 수 있다. 이러한 직선 왜곡은 잡음 이외에도 허프 공간의 설정, 특히 각 해상도의 설정에 영향을 받는다. 이 논문에서는 기존의 허프 변환에서 발생하는 이러한 직선 왜곡을 분석하고, 잡음 민감성을 줄이기 위해 제안된 경계선 강도 허프 변환(Edge Strength Hough Transform, ESHT)에서 이러한 왜곡이 적게 발생함을 보인다. 또한 ESHT에서만 발생할 수 있는 왜곡을 분석하고 해결방안을 제시한다. 제시한 방법에 의해 직선의 왜곡이 감소하는 것은 실험 결과를 통해 확인할 수 있다.

In the study, the moral sensitivity, moral distress, and biomedical ethics awareness levels of hospital nurses are examined, and the mediating effect of biomedical ethics awareness in the relationship between moral sensitivity and moral distress is verified. As the study subjects, 153 hospital nurses were selected from both university hospitals and general hospitals in S city and J city. Using the SPSS WIN 21.0 system, data analysis was conducted via t-tests, the Sheffe test, correlation analysis, multiple regression analyses, Sobel test. The average level of moral sensitivity experienced by the hospital nurses was 4.70(out of 7), moral distress was 62.80(out of 336), and biomedical ethics awareness was 2.21(out of 4). Moral distress had a static correlation with moral sensitivity and biochemical ethics awareness, and moral sensitivity had a static correlation with biomedical ethics awareness. Finally, biomedical ethics awareness showed a partial mediating effect in the relationship between moral sensitivity and moral distress. It is important to develop a biomedical ethics education program that can help hospital nurses to resolve moral issues, thereby improving moral sensitivity and diminishing their moral distress.

This study investigates the impact of social-face sensitivity of smartphones on the adoption of iPhone in China. Social-face sensitivity is divided into three dimensions, namely, other-directed sensitivity, self-directed sensitivity, and formality-directed sensitivity. We surveyed 218 university students in China through an online survey site. The results showed that formality-directed and other-directed sensitivity have significant impacts on iPhone preferences. Self-directed sensitivity was not significant. We investigated two moderate variables, namely, financial ability and brand sensitivity. Both variables showed significantly moderate impacts on the intention to purchase iPhone. The impact of social-face sensitivity on iPhone preferences implies that the iPhone has dual characteristics to the Chinese, namely, as utility and luxury goods. This finding offers managerial implications for Apple and other mobile service companies in terms of production and marketing strategies.

The purpose of this study was to investigate the effects of social face sensitivity on impulse buying tendency and satisfaction. This study was also to investigate the effects on the mediating effects of the impulse buying tendency in the relationship between social face sensitivity and satisfaction. For this purpose, this study was conducted to 266 subjects living in Busan, Korea. And the data was analyzed by SPSS 22 and Amos 25. The results of the study were as follows. First, others conscious social face and formality social face were related to impulse buying tendency. However, shame conscious social face was partially related to impulse buying tendency. Second, suggestion impulse buying and reminder impulse buying had significant effect on satisfaction, however stimulus impulse buying and pure impulse buying had not significant effect on satisfaction. Third, the empirical results showed others conscious social face had significant positive effect on satisfaction. But, formality social face and shame conscious social face have not significant effect on satisfaction. Finally, this study also found the mediating effects of the suggestion impulse buying and reminder impulse buying in the relation between others conscious social face and satisfaction. Based on the empirical results, implications focused on the social face sensitivity, impulse buying tendency and satisfaction were discussed.

Principal component analysis (PCA) is a well-known method for dimension reduction while maintaining most of the variation in data. Although PCA has been applied to many areas successfully, it is sensitive to outliers. Several variants of PCA have been proposed to resolve the problem and, among the variants, robust fuzzy PCA (RF-PCA) demonstrated promising results. RF-PCA uses fuzzy memberships to reduce the noise sensitivity. However, there are also problems in RF-PCA and the convergence property is one of them. RF-PCA uses two different objective functions to update memberships and principal components, which is the main reason of the lack of convergence property. The difference between two functions also slows the convergence and deteriorates the solutions of RF-PCA. In this paper, a variant of RF-PCA, called RF-PCA2, is proposed. RF-PCA2 uses an integrated objective function both for memberships and principal components. By using alternating optimization, RF-PCA2 is guaranteed to converge on a local optimum. Furthermore, RF-PCA2 converges faster than RF-PCA and the solutions found are more similar to the desired solutions than those of RF-PCA. Experimental results also support this.

This study analyzed the effects of women's SNS use on their alternative behaviors of managing health. This study paid attention to how women's behaviors of seeking information about poisonous menstrual products and alternative menstrual products would impact their intention to use alternative menstrual products. Mainly based on health belief model, 11 hypotheses were created and tested through a path analysis of survey data. Results from the path analysis indicated that SNS information about menstrual products were significantly associated with perceived advantage of alternative menstrual products and perceived sensitivity of poisonous menstrual products. In addition, four main factors-self-efficacy, perceived sensitivity, perceived advantage, and perceived disadvantage-were significantly associated with women's intention to use alternative menstrual products.
