The purpose of this study was to identify the competing values leadership of restaurant general managers and to investigate the impact of their competing values leadership on employee job satisfaction and turnover intention. A sample of full-time restaurant employees (n=360, 36% response) completed an e-mail survey. The results showed that among the eight sub-dimensions of competing values leadership roles, the monitor (4.04), producer (4.01), and director (3.99) roles were perceived as the most frequently used leadership styles of managers compared to broker (3.78), innovator (3.83), and mentor (3.91) roles (p <0.001). Additional T-test results suggested that an employees' gender had an influence on how he/she perceived the leadership style of their manager. Male employees were more likely to perceive that the director and mentor roles (4.19) were performed very well by their managers, while female employees perceived that their managers concentrated more on monitor (3.98) and producer (3.96) roles rather than on broker (3.73) and innovator (3.79) roles (p<0.05). It was found that manager competing values leadership had a significant correlation with employee job satisfaction, and the mentor, coordinator, and innovator manager roles explained the relationship with 42.1% based on multiple regression analysis (p<0.001). In further findings, the manager competing values leadership roles had an effect on employee turnover intention. The results of the data were as follows: mentor and facilitator roles promoted a decrease in employee turnover intention and the director role caused employee turnover intention to increase. Ultimately, this study will be useful for restaurant managers to guide the application of appropriate competing values leadership roles in order to strengthen employee job satisfaction and to reduce turnover intention.

This paper presents a basic theory of information flow from single sending point to multiple receiving points, where new theories of algebraic system called "Hybrid Vector Space" and flow vector space play important roles. Based on the theory, a new algorithm for finding maximum homogenous information flow is proposed, where homogenous information flow means the flow of the same contents of information delivered to multiple clients at a time. Effective multi-routing algorithms fur tree-shape delivery rout search are presented.

The newly established high speed railway station may function not only just as a traffic convergence but also as an energizing force with multiple roles in the context of municipal environment. As a result, the development of high speed railway station zone will be considered as great opportunities as well to enhance quality of life of the neighboring inhabitants, as to develop new footholds for the inner-municipal growth and mobilization. The main purpose of this article is to offer guidelines about the effects of development of the high speed railway station zone seen from multiple aspects of municipal lifes and functions. To attain this purpose, the definition of high speed railway station zone, its characteristics, and its roles will be handled with the case of advanced countries such as Japan and France. And some lessons will be proposed based on them.

The purpose of this study was to predict the stability of the future marriage by understanding the values of marriage, child and sex role among pre-parents. For this purpose, the values of marriage, child and sex roles were compared between male (N = 340) and female (N = 363) university students, Tajeon. The data were analyzed by statistical methods, such as mean, standard deviation, t-Test, F-Test, Multiple-Regression and Duncan Multiple Range Test. The results of this study were as follows ; 1) There were significant differences between male and female students in the values of marriage, child and sex role. 2) The most important demographical variable influencing to the values of marriage, child and sex role was sex. 3) With reagard to the collections between the values of marriage and the positive values of child were negative. But the correlations between the values of marriage and the preference for a son were positive. The correlations between the preference for a son and the values of sex role were also positive. With reagard to the correlations between the values of marriage and the values of sex roles were positive.

This research was designed to illuminate that work domains and family domains are not separated but interacting spheres and to suggest efficient coping strategies than alleviate work/family role conflicts. The subjects of this study were 395 employed professional wives living in Seoul. Korea. Survey methods were questionnaires. Data analysis strategies were percentile, frequency, one-way-anova and multiple classification analysis. The results were as follows; 1)Employed wives experienced time-based conflicts and strain-based role conflicts. This finding supports the scarcity approach that multiple roles inevitably create strain. 2) Individual, family and work-related variables were predictors of work/family role conflicts. This findings indicate that work domains and family domains cannot be regraded as separated spheres. 3) Employed wives tried to meet all the given roles demands not by reducing role responsibilities, but by increasing the efficiency of role performance. This finding reflects the characteristics of employed wives who try to perform successfully all the responsibilities. 4)The negative correlation of coping strategies and work/family role conflicts suggests that strategies can function effectively in alleviating the work/family role conflicts.

This study was conducted to identify adults' knowledge, dietary behavior related to sodium, and attitude towards. The purpose of this study is to examine the effects of the quality of multiple roles and psychological well-being upon parenting behavior among employed mothers. The subjects were 172 employed mothers living in Seoul, Korea. The results are as follows. First, the quality of parental role was related to all of subscales of parenting behaviors of employed mothers. Second, employed mothers' higher autonomy was significantly associated with greater intimacy and reasoning guidance in their parenting. Third, employed mothers with greater positive relationship and autonomy were more likely to exhibit limit setting. Finally, higher level of environmental mastery and autonomy was related to greater parental involvement. Mothers' psychological well being was not significantly related to mothers' responsiveness.

The purpose of this study is to investigate the influence of family-friendly life environment factors including local community's living environment satisfaction (safety, convenience, comfort, accessibility, exchange of neighbor satisfaction), family support facility satisfaction, family support program satisfaction and nurture and education environment satisfaction, and local community's living information accessibility on the effect of multiple roles of married men and women with children. Data were collected from 380 married men and women with children located Seoul, GyeongGi-Do, ChungCheongBuk-Do, and KyungSangNam-Do. The results show that, first of all, related to general trend of role satisfaction and role strain, the subjects have higher experience of role satisfaction than role strain. Secondly, the variables of social demography, such as monthly income, non-regular full-time working system, white collar occupation, number of children and level of education, and living environment variables, such as satisfaction of living environment stability and satisfaction of neighbor exchange in living environment were significantly related to role strain. Thirdly, social demography variables, such as average monthly earnings, gender (male), non-regular part-time working system, satisfaction of stability in living environment, and satisfaction of convenience in living environment were significantly related to role strain.

Ethylene regulates numerous aspects of plant growth and development. Multiple external and internal factors coordinate ethylene production in plant tissues. Transcriptional and post-translational regulations of ACC synthases (ACSs), which are key enzymes mediating a rate-limiting step in ethylene biosynthesis have been well characterized. However, the regulation and physiological roles of ACC oxidases (ACOs) that catalyze the final step of ethylene biosynthesis are largely unknown in Arabidopsis. Here, we show that Arabidopsis ACO1 exhibits a tissue-specific expression pattern that is regulated by multiple signals, and plays roles in the lateral root development in Arabidopsis. Histochemical analysis of the ACO1 promoter indicated that ACO1 expression was largely modulated by light and plant hormones in a tissue-specific manner. We demonstrated that point mutations in two E-box motifs on the ACO1 promoter reduce the light-regulated expression patterns of ACO1. The aco1-1 mutant showed reduced ethylene production in root tips compared to wild-type. In addition, aco1-1 displayed altered lateral root formation. Our results suggest that Arabidopsis ACO1 integrates various signals into the ethylene biosynthesis that is required for ACO1's intrinsic roles in root physiology.

This study use the influences of parenting style as perceived by and adult child and recognizes gender roles for the purpose of marriage perspectives. I provided a general tendency of parenting style as perceived by and adult child, recognize gender roles, and perspective of marriage to achieve the established goals. We analyzed the relative influence of socio-demographic characteristics, parenting style as perceived by and adult child and recognize gender roles for marriage perspectives. Finally, parenting style as perceived by and adult child are recognized gender roles mediated by the investigated influence of marriage perspectives. We used a structured questionnaire that targeted unmarried men and women 20 to 30 years of age to verify the this study. Data analysis used SPSS ver. 19.0; in addition, we performed reliability, frequency analysis, t-test, hierarchical regression analysis, multiple regression analysis, and variance inflation factor. Looking at these results, both adult children had a higher perception of rearing parents with the usual recognition of gender roles. The analysis indicated a conservative perspective of marriage. Adult children of mothers rearing and recognize gender roles sub-area of masculinity and femininity are perceived to be a significant change observed in marriage perspectives in addition to socio-demographic characteristics of gender and education. However, the relationship between parenting style, as perceived by adult child and marriage perspectives and as analyzed by recognize gender roles, did not have a mediating effect.

The purpose of this study is to find out the tendency of the new generation’s consumer roles and green consumption behavior for the environmental conservation. This study is also to reveal some fundamental information for an environmental education program which si able to support the new generation consumers to participate voluntarily in an environmental activity. The 500 subjects of this study were selected from the new generation consumers who wre residing in Seoul, 1998. The 414 data wre finally analyzed by Mean, t-Test, ANOVA, and Multiple Regression Analysis. The major findings were as follows: 1) the purchasing roles of the new generation consumer tended to be higher than the citizen participation’s roles. The variables with the higher score for the new generation’s green consumption behavior were in the rank of the isolation of environmental waste, the purchasing behavior of green product, the recycling environmental resource, and citizen’s participating roles in environmental activity. 2) the new generation’s consumer roles showed a significant differences, according to variables for the environmental value, environmental education, and participation of the environmental and societal activity 3) the green consumption behavior for the new generation consumers showed a significant differences, according to sex, environmental value, participation of the environmental and societal activity. 4) the most influential variables for the green consumption behavior of the new generation consumers were in the rank of consumer roles, educational values, and the participation of the environmental activity. As we see above, the consumer education for the new generations needs to focus on consumer’s roles that let them participate voluntarily in environmental and societal activity, as well as practice positively to use green environmental products whenever they select some items in the markets.
