Purpose - Environmental issues, climatic changes, and greenhouse gases are problems to be solved at a global level. With an increased emphasis on the environmental and social responsibility of the management of companies, the manner in which companies approach quality-oriented culture and their individual sustainability management are being discussed as truly important issues to help them secure their competitiveness and growth strategies. This study proposes strategic directions to help manufacturers not only in expanding their competitive quality-oriented company culture but also in strengthening their sustainability management abilities. This study conducts a literature review and empirical research to examine how significantly the variables of a quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. Research design, data, and methodology - To verify research models and hypotheses, the study examined 170 companies using a questionnaire survey conducted over six weeks, and involved the performance of data analysis on 146 samples. Questionnaire responses were calibrated based on a Likert scale. The study used the Smart PLS 2.0 program designed for PLS (partial least squares), an analysis instrument of SEM (structural equation modeling). The study then verified empirical research hypotheses working on reliability analysis, validity analysis, factorial analysis, and path analysis. Results - Among the nine hypotheses, four are accepted and the rest are rejected. A quality-oriented company culture focusing on customer-centered management significantly influenced the maintainability management performance of environmental integrity and social responsibility, while economic profitability was dismissed. A process-focused quality-oriented company culture was significantly concerned with economic profitability but not with environmental integrity or social responsibility. A supply-chain cooperative company culture had a significant effect on economic profitability but not on environmental integrity or social responsibility. Conclusion - This study proposes strategic directions to help manufacturers expand their competitive quality-oriented company culture as well as strengthen abilities with sustainability management. It conducts a literature review and empirical research to examine how significantly the variables of quality-oriented company culture, customer-centered management, and process-centered and supply chain management-centered cooperation affect sustainability management performance in relation to economic profitability, environmental integrity, and social responsibility. There are two main conclusions. First, companies should consider the need for social responsibility management and environmental transparent management-focused maintainability management as avenues to create new markets and business, thereby helping the companies secure a reputation for having a customer and process-centered quality-oriented company culture by creating shared values between supply chains and enabling win-win situations through cooperation. Second, we are marching towards a creative win-win era from a society of conflicts and ruptures. Companies should understand that social responsibility management and supply chain management (SCM)-focused cooperation are the foundations of sustainable development, as they try to improve their culture while pursuing both win-win relationships with interested parties and equity in various conflictive relations.

Purpose - This study examines the adverse press coverage that has increased in proportion to the remarkable growth of various kinds of franchise businesses in the food service industry. Today, the trust of franchisees in relation to their franchisor, and the maintenance of good relations between the two, has become a significant social issue. This study investigates relationship satisfaction and the long-term commitment between the franchisor and franchisee. Research design, data, methodology - We used a path analysis to investigate the relationship between justice and trust, trust and relationship satisfaction, justice and relationship satisfaction, trust and long-term commitment, and relationship satisfaction and long-term commitment. Structural Equation Modeling and a Sobel test were used to investigate the mediating effects of trust and relationship satisfaction. Data were collected from 237 Food Franchisees in Seoul and Gyeonggi Province in order to test the theoretical model and its hypotheses. Two research methodologies are generally used in the distribution management field. For this study, an empirical method was used. Results - A causal analysis was carried out to test if the research model has a sufficient fit index (for instance, χ² = 46.694, df = 10, p = .000, GFI = 0.946, AGFI = 0.850, RMR = 0.034, NFI = 0.966, CFI = 0.973), and the results showed that the model was sufficient, thus demonstrating the suitability of the research model. Each hypothesis had a positive influence, both on long-term commitment and relationship satisfaction. Justice with the franchisor had a positive influence on trust. Relation satisfaction cognized by franchisees was found to positively influence long-term commitment. The franchisee perception of justice in relation to the franchisor had no significant influence on long-term commitment. The study investigated the hypothesis that trust could mediate justice and long-term commitment, and that relationship satisfaction could also mediate long-term commitment Both trust and relationship satisfaction were found to be important for long-term commitment. Specifically, trust sub-factors and justice sub-factors influenced long-term commitment. Identification-based and knowledge-based trust were more important than calculus-based trust. Distributive justice was deemed more important than procedural justice; distributive justice should thus be strengthened. Conclusions - Both franchisor and franchisee were independent businesses. Evidently however, the franchisor could not ensure profit without long-term commitment from the franchisee. As for the success of the franchise business, the franchisor should carry out appropriate strategies leading to a satisfactory relationship. For example, transparency makes it possible to maintain and enhance trust and to improve relationship satisfaction. Just relations between franchisor and franchisee should make it possible to maintain and enhance the franchisee's trust. The franchisor should provide a variety of information with respect to the franchisee's business success. Finally, in order to improve the franchisee's long-term commitment, the franchisor should ensure a just approach with trust and relationship satisfaction among their strategies.

The effects of media violence on the delinquent behavior and violence of children and adolescent are controversial. However, a small but genuine association appears to exist between media violence and aggression or violence. At the present, for a considerable proportion of the population of children and adolescent, delinquent behavior and violence has become a major problem and a way of life. One factor contributing to this problem has been assumed to be the negative influence of mass media including television, drama, videotapes and fiction magazines and so on. Therefore, this paper is intended to discriminate the causal relationship of influence of mass media and juvenile delinquent behavior and violence and to provide nine hypotheses derived from reviewing the literature related to mass media and delinquent behavior. The nine hypotheses are as follows : 1. The presence of modeling mass media crime themes and the extent of interest in and exposure of children and adolescent to media violence themes will be positively correlated to their delinquent(aggressive) behavior. 2. A higher positive correlation will be revealed between interest in and exposure to media violence themes and aggressive behavior among adolescent having parental rejection than among adolescent not experiencing parental rejection. 3. A higher positive relationship will be found between interest in and exposure to mass media crime themes and delinquent behavior among youth having need deprivation than among youth not having need frustration. 4. A higher positive relationship will be presented between the presence of imitating mass media crime themes and interest in and exposure to media violence themes and delinquent or aggressive behavior among youth dysplaying their maladaptive character tendency than among those adolescent dysplaying adaptive character tendency. 5. A higher positively correlating relationship will be shown between interest in and exposure to mass media crime themes and delinquent behavior among youth with a higher scores of depressive trend than among those youth having few or no depression. 6. A higher positive relationship will be found between interest in and exposure to media violence themes and aggressive behavior among adolescent complaining of a high degree of psychosomatic complaints than among those youth having few or no psychosomatic complaints. 7. A higher positive correlation will be appeared between interest in and exposure to mass media crime themes and delinquent behavior among youth displaying aggressive impulsiveness than among those youth having few or no aggressive impulsiveness. 8. A higher positive relationship will be found between interest in and exposure to media violence themes and aggressive behavior among youth having antisocial character or neurotic character with weak ego functioning than among those adolescent not having antisocial character or neurotic character with weak ego functioning. 9. A higher positive correlation will be existed between interest in and exposure to mass media crime themes and delinquent behavior among adolescent displaying the lack of sociality than among those youth not having the lack of sociality. The above nine hypotheses will be tested by statistical methods including Chi-square test, simple correlation, principal component analysis, principal component regression analysis and LISREL path analysis.

This study tires to examine affects that job and socio-psychological stresses of female office workers influence job satisfaction, organization commitment, and leaving intentions. A complete data are collected by conducting a survey with 240 female office workers from 9 medical institutions regarded as almost general hospital in Seoul. It is analyzed that the relation between socio-psychological stress and job satisfaction, organization commitment, and leaving intentions by using t-test; analysis of variance; correlation analysis; principal component analysis; linear structural equation modeling; etc. The results of this study are summarized as following. First, as it was comprehended by specific characteristics of subjects that the female office workers' level of job and socio-psychological stress, job satisfaction, organizational commitment, and leaving intention, there were statistically significant distinctions from their age, marital status, presence of children, position in the organization, type of employment, and monthly average income. Second, this study regarded relationship between the female office workers' level of job and socio-psychological stresses, job satisfaction, organizational commitment, and leaving intention. Job and socio-psychological stresses were negatively correlated with job satisfaction and organizational commitment, but the stresses were positive with leaving intention. Third, after evaluating effect that 8 features related to the job stress could influence job stress, the most effective valuables were in order to unfairness in organizational structure, workplace culture, inadequate compensation, and relationship conflict. Fourth, when looking at the overall effects of the job and sociopsychological stresses on job satisfaction, organizational commitment, and leaving intention, work autonomy was the most influencing factor of work stress levels. The level of the job stress seemed to be a prevalent impact on the leaving intention and it showed the most negative relationship that path coefficient from leaving intention to organizational commitment and also from organizational commitment to job satisfaction. Based on these findings, it can be defined that the job and socio-psychological stresses strongly influence job satisfaction, organizational commitment, and leaving intention.

우리나라 청소년들은 하루 중 대부분 시간을 학교에서 입시 위주의 교육으로 지낸다. 많은 시간을 학교에서 보내기 때문에 학교생활의 적응 여부는 청소년의 학업성취도 및 생활만족도와 관계가 있고 길게는 사회생활에까지 영향을 미치므로 그 중요성이 크다고 할 수 있다. 학교적응에 많은 영향을 미치는 요인 중의 하나로 청소년기의 심리적 불안을 고려해 볼 수 있다. 청소년의 가정환경은 불안에 영향을 미치는 주요 요인으로 알려졌으며, 그중 부부갈등이 가정환경에 미치는 영향력은 아주 크다고 할 수 있다. 가정에서 부부가 심하게 싸울수록 자녀는 분노, 슬픔, 걱정 등 부정적인 감정을 더 많이 느꼈으며, 부부갈등의 문제가 자녀 자신에 관한 내용일수록 그 정도는 더욱 심하게 나타났다. 본 연구는 이러한 이론적 배경을 근거로 부부갈등이 청소년의 불안과 학교적응에 어떻게 영향을 미치는가를 구조방정식 모형을 통하여 분석하였다. 분석결과 부부갈등 강도와 부부갈등 내용은 청소년의 불안감에 영향을 주었으며, 불안감은 학교 교우들과의 적응에 부정적인 영향을 미쳤다. 그러나 부부갈등 해결은 불안감에 영향을 미치진 않았지만, 학교 교우적응과 수업적응에 직접적으로 부정적인 영향을 미쳤다.

3GPP2가 제안하는 방식에서는 Macro Mobility 지원을 위하여 MIP를 이용하며 PDSN은 FA의 기능을 수행한다. 이때 하나의 PDSN에서 다른 PDSN으로 MS가 이동할 경우 지원되는 이동성을 Macro Mobility라 하며, PDSN 관리 영역 내의 하나의 RN에서 다른 RN으로 이동 시에 지원되는 이동성을 Micro Mobility라 한다. 3GPP2가 제안하는 방식에서는 PDSN이 FA의 역할을 수행하므로 이동성 지원이 가능하지만, 이는 Macro Mobility를 지원하기 위한 메커니즘으로, Micro Mobility를 지원하기엔 빠르고 Seamless한 핸드오프에 취약하다. 본 논문은 Micro Mobility를 지원하기 위한 멀티캐스트 그룹 메커니즘 기반의 Seamless 핸드오프 알고리즘을 제안하고 있다. 제안된 알고리즘은 MS의 이동방향과 속도를 계산하여, 예상 이동경로에 인접한 RN들을 멀티캐스트 그룹으로 구성하고, 그룹 join 시점을 최대한 늦춤으로서 망의 효율성을 높인다. 또한, 기존의 멀티캐스트 연결 방법이 가지고 있는 버퍼 오버헤드에 대한 문제점을 해결하기 위해, RN은 예상 핸드오프 시간 이후의 데이터만을 버퍼링 한다. 제안된 알고리즘의 Deadlock Freeness 및 Liveness를 검증하기 위해 State Transition Diagram을 작성하고, 페트리네트 모델을 이용 도달성 트리를 작성하였다. 또한, 시뮬레이션을 통한 성능분석을 수행하였다.
