Organ(1988) has suggested that OCB should be considered an important component of job performance because citizenship behaviors are part of the spontaneous and innovative behaviors. Also it has been suggested that organizational characteristics may potentially explain many organizational behavior outcome variables(Hackman & Oldham, 1980). In recent years there has been a resurgence of interest in the validity of personality measures as a moderator between many variables and organizational outcome variables. This is largely due to the facts that first personality is difficult to control for promoting many organizational outcomes and next many researchers have found the moderating effects of personality(Brief & Aldag, 1975; Wanous, 1974). The purpose of this research is to test the moderating effects of tenure and growth needs on the relationships between organizational characteristics and OCB. To assess the moderating effects, the hierarchical regression procedures outlined by Cohen and Cohen(1983) were followed. On the basis of data from 698 teachers in Wonju province, results indicated that job variety has more impacts than any other independent variable on OCB like other studies. It is found that job variety and job identity have more impacts on courtesy and altruism in lower growth needs group than in higher growth needs group. Also it is resulted that job importance and autonomy have more impacts on sportsmanship in higher growth needs group than in lower growth needs group.

BACKGROUND/OBJECTIVES: Easy access to intervention and support for certain behaviors is important for obesity prevention and management. The available technology such as smartphone applications can be used for intervention regarding healthy food choices for obesity prevention and management in elementary-school students. The transtheoretical model (TTM) is comprised of stages and processes of change and can be adopted to tailored education for behavioral change. This study aims to develop TTM-based nutrition contents for mobile applications intended to change eating behaviors related to weight gain in young children. SUBJECTS/METHODS: A synthesized algorithm for tailored nutrition messages was developed according to the intake status of six food groups (vegetables, fruits, sugar-sweetened beverages, fast food and instant food, snacks, and late-night snacks), decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. The messages in this study were developed from December 2014 to April 2015. After the validity evaluation of the contents through expert consultation, tailored nutrition information messages and educational contents were developed based on the TTM. RESULTS: Based on the TTM, stages of subjects are determined by their current intake status, decision to make dietary behavioral changes, and self-confidence in dietary behavioral changes. Three versions of tailored nutrition messages at each TTM stage were developed so as to not send the same messages for three weeks at most, and visual materials such as figures and tables were developed to provide additional nutritional information. Finally, 3,276 tailored nutrition messages and 60 nutrition contents for applications were developed. CONCLUSIONS: Smartphone applications may be an innovative medium to deliver interventions for eating behavior changes directly to individuals with favorable cost-effectiveness. In addition, using the TTM for tailored nutrition education for healthy eating is an effective approach.

This study compared the innovative characteristics of science teachers who participated in the First Student Science Inquiry Olympic and those of science teachers who did not participate in the event. The subjects were science teachers in three groups: (1) the active participants in the Inquiry Olympic who supervised the students contestants, (2) the observers of the Inquiry Olympic who came to see the event, and (3) the ordinary teachers who did not come to the Inquiry Olympic and were sampled through stratified cluster sampling. The study instrument was a questionnaire; all the subjects received the survey questionnaire by mail. The return rate was 45%. In general, the Inquiry Olympic participants(both the student supervisors and the observers) demonstrated different characteristics from the nonparticipants in four categories. Firstly, the Inquiry Olympic participants showed higher level of self actualization, for example, interest in science education, higher inner motivation, stronger desire to innovate than did the nonparticipants. Secondly, the participants demonstrated more involvement in professional activities and greater degree of upward social mobility than the nonparticipants. Thirdly, the participants had communication behaviors different from nonparticipants, e. g.. greater leadership of public opinions, more experience of contact with the change agent, greater tendency to regard their school society as modern. Lastly, the participants had higher social status than the nonparticipants. Implications and suggestions are made for the utilization of the innovation-oriented science teachers to implement of innovations in the future.

In this study, the explicit numerical algorithm was proposed to simulate the stress erection process and ultimate-load analysis of the strarch (stressed arch) system. The strarch system is a unique and innovative structural system and member prestress comprising prefabricated plane truss frames erected through a post-tensioning stress erection procedure. The flexible bottom chord, which has sleeve and gap details, is closed by the reaction force of the prestressing tendon. The prestress imposed on the tendon will enable the strarch system to be erected. This post-tensioning process is called "stress erection process." During this process, plastic rigid-body rotation occurs to the flexible top chord due to the excessive amount of plastic strain, and the structural characteristic is unstable. In this study, the dynamic relaxation method (DRM) was adopted to calculate the nonlinear equilibrium equation of the system, and a displacement-based finite-element-formulated filament beam element was used to simulate the nonlinear behavior of the top chord sections of the strarch system. The section of the filament beam element was composed by the amount of filaments, which can be modeled by various material models. The Ramberg-Osgood and bilinear kinematic elastic plastic material models were formulated for the nonlinear material behaviors of the filaments. The numerical results that were obtained in the present study were compared with the experiment results of the stress erection and with the results of the ultimate-load analysis of the strarch unit frame. The results of the present studies are in good agreement with the previous experiment results, and the explicit DRM enabled the analysis of the post-buckling behaviors of the strarch unit frame.

The concept of Mydata emerged with the expansion of the data economy. MyData aims to empower individuals by enhancing their right to self-determination over their personal data. The use of MyData is expected to enable the provision of innovative service in various fields. Since 2022, MyData has been introduced and actively used in the financial sector. In the future, not only financial institutions but also Bigtech and Fintech companies are expected to actively join and demonstrate rapid expansion. To ensure steady growth for MyData in the financial sector, it is necessary to assess acceptance behaviors from multiple perspectives. However, the majority of existing research solely focuses on positive acceptance. This study analyzed the impact of users' personal characteristics and innovation characteristics on both innovation resistance and acceptance resistance. The analysis revealed that personal and innovation characteristics contribute to an increase in distrust and innovation resistance in the MyData service. In addition, it has been confirmed that it can lead to actions such as delayed acceptance and refusal to accept. The results of this study offer both theoretical and practical insights into user behavior within the MyData service market.

Maniac consumers have a ripple effect on marketing because they are the main body of trends and consumer economy. So It is very important that we should first read needs and wants - in other words, psychological motives. And then we should find maniac consumer segments. This is an exploratory study that was done to obtain an insight for the new maniac consumer market segmentation. It examined the definition and characteristics of digital maniacs in Korea, and it carried out a literature study on consumers who have a similar consumption trend as the maniac users as a pre-study. Also, it looked into the trends and values of the maniac community in Korea, using the previous study's scale for innovative consumers. Next, the study interviewed maniac users using the first data and focused on discovering and grouping the new maniac segments based on the results. The study analyzed the purchase behaviors, decision-making, attitude for involvement and potential needs of the digital maniacs in Korea, and it discovered the segments for the segmentation of maniacs so it could find out the disposition and status of the digital maniacs. Such approach can be used as a strategical due for maniac target marketing and design(customer-oriented marketing and design) in the future.

Today's rapidly changing healthcare environment and increasingly professional nursing practice indicate that identifying leadership characteristic of nursing leaders and executives is a vital importance in today' s time and also mandate innovative leadership for nursing service. Therefore, the purpose of this study is to examined the transformational, transactional leadership styles of the Nurse Administrators. The sample consisted of sixteen mid-level nurse administrators, fifty head nurses of 5 General Hospital. Data for this study was collected from Sep. 20 to 29 by Bass' MLQ Questionnaire. The data was analyzed by frequency, percentage, one-way ANOVA. Major findings are as follows : Appropriate one-way ANOVA tests revealed that the differences for transformational and transactional leadership styles of nurse executives, mid-level nurse administrators as perceived by their immediate subordinates were statistically significant(P<.05). The scores of transformational and contingent reward behaviors were declined of the mid-level nurse administrators. The transactional scores of nurse administrators were lower than transformational ones, which is a desirable findings. The result of this study, the mid-level nurses administrators were perceived as the highest transformational leader by their subordinates. The nurse executives received the lower transformational leadership scores than mid-leval administrators. These results were opposit to the previous studies. Leader can aspire to these qualities of transformational leadership, building on the more traditional transactional dimensions. We can think that transformational leadership suggests a direction for developing a creative and rewarding approach to the leadership of professionalnursing practice environments. More research on transformational qualities in nursing service and controlled designs would be desirable for nursing service administration.

In social commerce, consumers can buy products at much cheaper price if the required minimum number of buyers are made. Social commerce has showed rapid growth as an innovative distribution system receiving highlights, however it is true that it hasn't been sufficiently studied. The purpose of the study for presents the direction of growth of the fashion industry with social commerce through qualitative studies. This study is to make a preference group of four people and a non-preference group of four people of social commerce users for the fashion items sold social commerce market and lastly proposes some improvements. The 'preference group' showed high familiarity and preference to social commerce; and they had the tendency of the pursuit of convenience and voluptuous shopping. The revisit of 'non-preference group' preferred open market and, had the tendency of economical shopping and, they are favorable to other categories of social commerce. The reasons of preference were that accessibility was good in fashion products purchasing behaviors in social commerce and, it was convenient and, price was good and new information on cheap and good products were provided; the reasons of non-preference were that the quality of the products and genuineness of articles are doubtful or, the price is not the lowest or, the carried over products were majority. In the perspective of the fashion products in social commerce they answered that it would be brighter but improvements are needed such as supplying exact information, the lowest price, diversified products and the subdivision of category.
