This paper Proposes the individual roles for developing small web application systems based on the Client/Server architecture with the activities and artifacts of each role and cooperation. The roles of Web Server part (i.e. User Interface Designer, Web Designer, HTML Writer), the roles of Application Server part (i.e. Domain Expert, Application Developer, Tester) and the roles of DB Server part (i.e. Database Administrator, Data Designer) are described. Furthermore, the role of the Development Leader that participates in development and manages all works in project and finds the solutions of problems in project, is also discussed. The Domain Expert analyzes the domain of the application in order to send the artifacts to the Application Developer. Then the Application Developer analyzes, designs and implements the application based on the artifacts of the Domain Expert and integrates the implemented program modules. Roles are related each other in this way, and cooperate until the application development is completed. Finally, we analyzed and compared these roles with the roles of RUP(Rational Unified process) and web wave. Suggested roles in this paper turned out to be efficient compared to the roles of the existing large-scale methodology.

As information is the critical resource of business, CIOs(chief information officers)' managerial roles become more important. CIOs work out the organization and information system strategies, introduce changes into organizations, communicate with chief executive officers and users, and take the responsibilities of the information system operation. The CIOs' managerial roles make affects on the information system performance and the organizational effectiveness. They are divided into six sub-roles; leader, liaison, entrepreneur, monitor, resource allocator and spokesman. The CIOs' influences on organizations are evaluated by information systems performance. User information satisfaction is one of the most valid information system evaluation criterions. User participation and user involvement are regarded as the antecedents of user satisfaction. This study investigates the effect of CIOs' managerial roles on user satisfaction, user participation, user involvement, CIOs' six managerial roles do not equally influence users. The results of this study have implications for the CIOs' managerial roles in organizations. As CIOs effectively perform managerial roles, user satisfaction is improved.

This current study was designed to explore the meaning of being a mother and a father in contemporary Korean society by examining their roles perceived by mothers and fathers with children at different developmental stages. A total of three hundred and ninety four couples with children aged from one to seventeen years were recruited for the study, and they were asked to complete a set of questionnaires about paternal and maternal roles each. A modified version of Generative Fathering Scales by Lee et al.(1999), was used to measure the roles perceived by fathers and mothers in two areas: (1) parenting responsibilities and (2) involvement in childrearing practices. The parental roles, as expected, were viewed differently by the surveyees with children at different ages: the younger child/ren a father has, the more involvement he emphasizes in childrearing. These results indicate that the roles of mothers and fathers should be considered in the context of developing children.

Objectives : Most studies about multiple roles and women's health suggested that combining with paid job, being married and having children was more likely to improve health status than in case of single or traditional roles. We investigated whether there was better health outcome in multiple roles among Korean women coinciding with previous studies of other nations. Methods : Data were from the 2005 Korea National Health & Nutritional Examination Survey, a subsample of women aged 25-59 years (N=2,943). Health status was assessed for self-rated poor health, perceived stress and depression, respectively based on one questionnaire item. The age-standardized prevalence of all health outcomes were calculated by role categories and socioeconomic status. Multiple logistic regression was used to assess the association of self rated health, perceived stress, and depression with multiple roles adjusted for age, education, household income, number of children and age of children. Results : Having multiple roles with working role was not associated with better health and psychological wellbeing. Compared to those with traditional roles, employed women more frequently experienced perceived stress, with marital and/or parental roles. Non-working single mothers suffered depression more often than women with traditional roles or other role occupancy. Socioeconomic status indicators were potent independent correlates of self-rated health and perceived stress. Conclusions : Employment of women with other roles did not confer additional health benefit to traditional family responsibility. Juggling of work and family responsibility appeared more stressful than traditional unemployed parental and marital role in Korean women.

Posttranscriptional regulation of RNA metabolism, including RNA processing, intron splicing, editing, RNA export, and decay, is increasingly regarded as an essential step for fine-tuning the regulation of gene expression in eukaryotes. RNA-binding proteins (RBPs) are central regulatory factors controlling posttranscriptional RNA metabolism during plant growth, development, and stress responses. Although functional roles of diverse RBPs in living organisms have been determined during the last decades, our understanding of the functional roles of RBPs in plants is lagging far behind our understanding of those in other organisms, including animals, bacteria, and viruses. However, recent functional analysis of multiple RBP family members involved in plant RNA metabolism and elucidation of the mechanistic roles of RBPs shed light on the cellular roles of diverse RBPs in growth, development, and stress responses of plants. In this review, we will discuss recent studies demonstrating the emerging roles of multiple RBP family members that play essential roles in RNA metabolism during plant growth, development, and stress responses.

This study, guided by Engeström's (1999, 2001) activity theory which owes its theoretical lineage to sociocultural theory, explores how roles (peer feedback givers and receivers) and tasks are distributed among EFL students who engage in peer response. More specifically, as an extension of previous research of focusing on "stances" ESL students adopt, I investigate whether different roles in peer response groups make a difference in the nature of peer response and identify what underlays the different roles in peer group interaction. In addition, I examine whether different roles to the peer response create tensions and contradictions in peer response and how these created conflicts lead to changes in peer response activity system. The data I wish to consider is first-person narratives elicited from two EFL college students. I use Won's and Choi's (both pseudonyms) stories as a heuristic, which is a method that allowing one to proceed fruitfully in finding information. Foregrounded in this study are the students' different roles in the same peer response activity. A division of labor exists between Won/Choi and their peers - the way tasks are divided up and the way roles are structured. Yet Won and Choi adopted rather divergent roles when participating in peer response activity and carried out qualitatively different peer response activities. It is obvious here that the distribution of their roles in carrying out this particular peer response is shaped by Won' and Choi's perception about the validity of their peers' responses.

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 study was based on a recognition that the married mens role of performing multiple roles should be redefined. Family and work roles were composed of four domains, such as marital, parental, homecare, and occupational roles. The data of this study had been collected from the married men, who had his spouse and his first child younger than twelve years old, and held a job in Seoul. The main findings of this study were as follows: First, as for family and work role salience perceptions, it showed that men relatively higher perceived four role saliences: marital role salience, parental role salience, homecare role salience, and occupational role salience. Second, among four salience perceptions of family and work roles, married men highest perceived homecare role salience while they lowest perceived occupational role salience. Third, regarding the married mens family and work role performances, the parental and homecare roles were equally performed and higher than the marital and occupational roles. In general, the degree of family and work role salience perceptions of the married men in Korean society was higher than that of family and work role performances.
