This study is to understand the logistic area effect for the satisfaction of military service; service people work the unit of Marine Corps which is close or far away from North Korea and infantry people from the structural equation models based on the component based method(PLS). From the result, we note that the trustworthy and suitability of supply are the most important factors in their of military service satisfaction for Marine Corps.

본 연구는 부산항에서 차지하는 환적물동량의 위상을 고려하여 환적화물에 대한 정확한 예측을 위한 모델을 수립하는데 그 목적이 있다. 환적물량을 결정짓는 요소로는 부산항의 경쟁력 뿐 아니라 중국 등의 수출입 물동량 증가량과 중국항만의 경쟁력도 중요요소이며, 이들 요소들이 상호간에 영향을 주고 받음에 따라 그러한 순환적 인과관계 분석에 적합한 시스템 다이내믹스(SD) 기법을 활용하여 환적화물에 대한 예측을 시도해 보고자 한다.

The purpose of this study is to look for the factors that facilitate knowledge sharing among public official in the department of social welfare, and to find whether the intention to share knowledge influences the knowledge sharing. In order to accomplish the purpose of the research model, the independent variables were trust, openness in communication, anticipated reciprocal relationship, and efficacy. The intervening variable was intention to share knowledge, and the dependent variable was knowledge sharing. The significant finding that came out of this research model is that trust, anticipated reciprocal relationship and efficacy positively influenced the intention to share knowledge. Efficacy positively affected knowledge sharing. Intention to share knowledge had a significant influence on the knowledge sharing. According to the results of this study, in order to improve effective knowledge sharing in the public sector or in the private sector, we suggested that social workers have to consider why they should share knowledge in the social welfare organization. Social workers in the public sector or in the private sector must develop ways to share the knowledge possessed within the organization with the people who need that knowledge.

This study examined the dynamic relationship between urbanization and energy consumption in China. As an alternative to the conventional method of having the same integration of time series and large samples, ARDL method and Toda-Yamamoto causality analysis were applied. As a result, urbanization income, income, and energy consumption have a long-term stable equilibrium. Urbanization and income have a positive effect on energy consumption in the long run, but short-term changes of urbanization and income have no significant effect on energy consumption changes. The adjusted coefficient was -0.2395, which was statistically significant. In the causality test, income and energy consumption are useful to predict each other, but urbanization is exogenous because there are no causality with other variables. Since the process of urbanization in China has been proceeding slowly and deliberately by the government, it can be seen that the long-term effects of urbanization are clear and exogenous.

The basic purpose of this study is to investigate service quality and relationship quality affecting the result of long-term relationship between service buyers and suppliers. This research presented a constructive model(service quality${\rightarrow}$relationship quality${\rightarrow}$customer's revisiting intention) and then propose the research model base on prior researches and studies about relationships among components of service. Data were gathered from respondents who visit traditional markets. For this study, data were analyzed by SPSS and AMOS 5.0. Data were gathered from 209 respondents in the Korean traditional market. This research proposed 6 hypotheses on 5 latent variables and tested through structural equation modeling. 5 alternative measurements were compared through statistical significance test of the paths of research model and the overall fitting level of structural equation model. and the result was successful. The results of the study indicate that service quality is properly modeled as an antecedent of relationship quality and revisiting intentions. We also discussed managerial implications of the study and its limitations.

This article has examined the international transmission of returns among S&P500, Nikkei225 and SENSEX stock index cash markets using the daily closing prices covered from January 4, 2002 to February 6, 2009. For this purpose we employed dynamic time series models such as the Granger causality analysis and variance decomposition analysis based on VAR model. The main empirical results are as follows; First, according to Granger causality tests we find that S&P500 stock index has a significant prediction power on the changes of SENSEX and Nikkei225 stock index market and vice versa. However, US stock market's influence is dominant to the other stock markets at a significant level statistically. Second, according to variance decomposition, SENSEX stock index is more sensitive to the movement of S&P500 than that of Nikkei225 stock index. These kinds of empirical results shows that the three stock markets are integrated over times and these results will be informative for the international investors to build the world-wide investment portfolio and risk management strategies, etc.

This study aims to investigate how perceived interactivity between the mobile messenger application and its user gives rise to user's enjoyment and continuous usage intention. Perceived interactivity was assumed to be formed by the combination of control, share, and responsiveness in light of the previous studies. The relations between perceived interactivity, enjoyment, and usage intention are hypothesized on the basis of the pleasure-arousal-dominance emotional state model, the theory of reasoned action, and the theory of planned behavior. Survey data were collected from 481 mobile messenger users in Korea and China. In order to test hypotheses, structural equation modeling analyses were conducted. As a result, perceived interactivity concerning connectedness and responsiveness not only positively affected enjoyment, but also had a significant effect on usage intention. However, while control positively influenced usage intention, it was not significantly related to enjoyment. In addition, there was a positive relation between enjoyment and usage intention. Incidentally, multi-group analysis was conducted to explore the differences between Korean and Chinese users. The findings would provide managerial implications for mobile messenger corporations on causal effects of perceived interactivity and the differences of the path coefficients between in Korea and China.

최근 조직 내 정보시스템이 제공하는 지식과 정보에 대한 공유와 교환이 더 이상 성공적이라고 판단되지 않음에 따라 그 대안으로써 가상공동체(Virtual Community)가 주목받고 있다. 그러나, 가상공동체에서 살아있는 지식과 정보의 공유를 위해서는 공동체 안의 구성원인 리더와 구성원(팔로워) 들의 상호작용을 통한 몰입이 매우 중요하다는 인식이 확산되었다. 그러나, 이러한 몰입에 영향을 주는 리더-구성원 간의 영향관계는 충분히 연구된 바 없다. 이에 본 연구는 가상공동체에서 리더의 리더십 스타일과 팔로워의 특성 그리고 이들 간의 동기와 신뢰가 가상공동체의 몰입에 미치는 인과관계에 대해 분석하고자 하였다. '지각된 리더의 배려'로 측정된 '서번트 리더십'과 '지각된 리더의 조직지향'을 통해 측정된 '변혁적 리더십'이 구성원의 팔로워십과 동기, 리더와 조직에 대한 신뢰에 어떠한 영향을 미치는지 460명의 가상공동체 구성원을 통해 실증적으로 분석하였다. 분석결과 서번트 리더십과 구성원의 팔로워십 특성이 구성원의 몰입에 있어서 중요한 역할을 수행함을 알 수 있었다.

같은 상황이라도 사람에 따라 느끼는 감정은 다르다. 따라서 감정을 일반화하여 현재의 감정 상태를 정량적으로 표현하는데 는 한계가 있다. 본 논문은 현재의 감정 상태를 나타내기 위해, 인간의 감정을 모델링한 심리학의 감정 모델을 공학적으로 접근하여 심리학기반 공학적 인공감정을 제안한다. 제안된 인공감정은 심리학을 기반으로 감정발생의 인과관계, 성격에 따른 감정의 차이, 시간에 따른 감정의 차이, 연속된 감정자극에 따른 감정의 차이, 감정간의 상호관계에 따른 감정의 차이를 반영하여 구성했다. 현재의 감정 상태를 위치로 나타내기 위해서 감정장을 제안했고, 감정장 상의 위치와 위치에 따른 색깔로 현재의 감정 상태를 표현했다. 감정상태의 변화를 제안된 인공감정을 통해 시각화해보기 위해 셰익스피어의 '햄릿'에서 극중 등장인물인 햄릿의 감정변화를 제안된 인공감정을 통해 시각화 해 보였다.
