Hoe-Chang Yang,Sang-Ho Han 한국유통과학회 2013 한국유통과학회 학술대회 논문집 Vol.2013 No.-

The purpose of this study is attempted to identify any influencing relationship between the antecedent variables and the members' innovative work behavior that were expected to influence organizational performance based on the theory of planned behavior (TPB) and the extended theory of planned behavior (ETPB). Specifically, we conducted attitude as intrinsic motivation, perceived behavioral control as self-efficacy, subjective norm as value based on TPB, and other influencing variable as self-enhancement based on ETPB. Also, it was attempted to find out whether or not transformational leadership played the role of a moderator variable between each variable and innovative work behavior. The survey was conducted SMEs in Seoul and metropolitan area. 158 copies of effective questionnaires were used. We analyzed CFA, Cronbach’s α and correlation analysis, regression analysis and multiple regression using SPSS 19.0 and AMOS 19.0. It was found that self-efficacy, value, intrinsic motivation and self-enhancing bias have been found out to have a positive relationship respectively with innovative work behavior. And the transformational leadership has moderated to have a statistically significant negative influence between value, intrinsic motivation and innovative work behavior, respectively. These results suggested that leaders will be successful in winning members' trust through conducting their behaviors as fitted to the applicable ethical and moral standards and through their fair, transparent and legitimate management practiced in an attitude of 'taking the initiative and setting an example,' solving such problems is well expected to be made possible.

Sang-Ho Han,Hee-Young Cho,Hoe-Chang Yang 한국유통과학회 2014 Asian Journal of Business Environment (AJBE) Vol.4 No.1

service advertising (PSA) and commercial advertisements on consumers' social and emotional values. Specifically, we include source credibility on advertising models as a mediating variable to compare the path difference between the social and emotional value of consumers, and to test the appropriateness of advertising expenses. Research design, data, and methodology – A total of 219 copies of effective questionnaires were used and methodologies such as Cronbach’s alpha, paired samples t-test, and structural equation modeling (SEM) were conducted. Results – The results showed that the consumer model was effective at PSA, while celebrities and CEOs were effective at commercial advertising. Further, only credibility (among source credibility) made a significant difference in the test of PSA models of both PSA and commercial advertising that consumers preferred. Conclusions – The advertising model types varied depending on advertising types (for example, PSA and commercial advertising). Therefore, celebrities and CEOs appearing in commercial advertising should have no ethical or moral defect by self-control, and marketers should elect the model considering such a fact.

In this study, it was attempted to identify the clues for the value promotion that may be operated as a consumers' motive by shedding new light on the consumer value as well as by reconstructing each of the variables that had been analyzed in the meantime through the means-end chain theory(MEC). In this study, 202 copies of effective questionnaires were used by Yang & Ju(2012)’s data. As a result of the study, there are at least four important managerial or theoretical implications from this study: First, all of the store selection attributes were verified to have positive influence on the relationship quality. Second, even though the store selection attributes had been verified to exert positive(+) influence on the relationship quality, according to the verification result of the mediating effect, the consumer value was verified to be influenced only by the relationship quality rather than by the store selection attributes. Third, as a result of the path analysis on the proposed model after modification, with regard to the relationship quality of the general supermarkets in our country, it was verified that only the product factor had a statistically significant positive(+) influence and also that the social value was completely mediating between the relationship quality and the emotional value. Lastly, it may be pointed out that the concept of the MEC would be applicable to the cause and effect relationship model.

Effects of Advertising depending upon Type of Advertising and Form of Advertising Model

Hoe Chang Yang,Ho Keun Ahn,Sang Ho Han 한국유통과학회 2013 유통과학연구 Vol.11 No.11

Purpose - This study investigated whether there are differences in advertising effects depending on the type of advertising, divided into public service announcements (PSA) and commercial advertisements, and the form of advertising model. Research Design, Data, and Methodology - By investigating the difference in advertising effects due to the type of advertising and form of advertising model, the study was expected to reveal the optimal advertisements for achieving the desired advertising effects. The subjects were Jangan University students in their first and second year, with 102 copies of the survey questionnaire received for analysis. Results - The findings were different for the celebrities, professionals, and CEOs, except for the PSA; further, they were different among celebrities, professionals and the other types of model, except CEO, in commercial advertising. Simple regression results showed that both the professionals and CEO models had a positive impact on the effect of advertising in the case of the PSA. Conclusion - These results suggested that appropriate selection of the form of advertising model is a very important factor. Conversely, it has been suggested that the celebrity model is the most effective, reflecting the trend for commercial advertisements.

Chang Yell Shin,Mi Young Jung,In Ki Lee,Miwon Son,Dong Sung Kim,Joong In Lim,Soon Hoe Kim,Moohi Yoo,Tae Lin Huh,Young Taek Sohn,Won Bae Kim 대한약학회 2004 Archives of Pharmacal Research Vol.27 No.1

DA-11004 is a synthetic, potent NADP-dependent isocitrate dehydrogenase (IDPc) inhibitor where IC50 for IDPc is 1.49 mM. The purpose of this study was to evaluate the effects of DA- 11004 on the high fat high sucrose (HF)-induced obesity in male C57BL/6J mice. After completing a 8-week period of experimentation, the mice were sacrificed 1hr after the last DA- 11004 treatment and their blood, liver, and adipose tissues (epididymal and retroperitoneal fat) were collected. There was a significant difference in the pattern of increasing body weight between the HF control and the DA-11004 group. In the DA-11004 (100 mg/kg) treated group the increase in body weight significantly declined and a content of epididymal fat and retroperitoneal fat was also significantly decreased as opposed to the HF control. DA-11004 (100 mg/ kg) inhibited the IDPc activity, and thus, NADPH levels in plasma and the levels of free fatty acid (FFA) or glucose in plasma were less than the levels of the HF control group. In conclusion, DA-11004 inhibited the fatty acid synthesis in adipose tissues via IDPc inhibition, and it decreased the plasma glucose levels and FFA in HF diet-induced obesity of C57BL/6J mice.

Due to the development of the network, modules can control the home appliances by using the applications on smart devices and also monitor the condition of houses by using the built-in camera in smart devices. And, power control, physical control, natural ecosystem can be controlled on the smart device applications by using the network communications. The skills to do so are implemented to technologies. But since the smart appliances use different protocols, there has been a problem in a matter of product compatibility. In this paper, we design An XML schema on devices for collaboration between devices and implement the device manager, which defines the relationships to enable collaboration between devices. When the device’s relationship is redefined by the manager, we used the compact embedded system in Arduino and OpenWRT while designed and implemented the prototype system that enables collaboration between devices through an XML schema.

Purpose – This study aims to find clues necessary for the direction of leadership development suitable for the current situation by exploring the direction in which leadership has been studied from the perspective of domestic researchers, along with the arrangement of leadership theories studied in various ways. Research design, data, and methodology – A total of 7,425 papers were obtained due to the search, and 5,810 papers with English abstracts were used for analysis. For analysis, word frequency analysis, word clouding, and co-occurrence were confirmed using Python 3.7. In addition, after classifying topics related to research trends through BERTopic and LDA, trends were identified through dynamic topic modeling and OLS regression analysis. Result – As a result of the BERTopic, 14 topics such as ‘Leadership management and performance’ and ‘Sports leadership’ were derived. As a result of conducting LDA on 1,976 outliers, five topics were derived. As a result of trend analysis on topics by year, it was confirmed that five topics, such as 'military police leadership' received relative attention. Conclusion – Through the results of this study, a study on the reinterpretation of past leadership studies, a study on LMX with an expanded perspective, and a study on integrated leadership sub-factors of modern leadership theory were proposed.
