The increasing trend of the five violent crimes (murder, robbery, rape, violence, theft) in Korea is not independent of social and economic factors. Several social science research have discussed about this issue but most of them do not properly reflect the nature of the time-series data. Based on several time series models, we studied about the endogenous factors (time, seasonal and cycle factors) and exogenous factors (economical, social change and crime control factors) on violent crime occur in Korea. Autocorrelation were also taken into account. Through this study, we want to help to make preventive policy by explaining the cause of violent crime and predicting the future incidence of it.

This study aimed to address whether the varying degree of screen speed in the context of a Virtual reality exergame will interact with users' intrinsic motivation in influencing user perceptions. Results from our experiment (N = 40), showed that screen speed and intrinsic motivation have significantly interacted in influencing players' feeling of flow, attitude, and intention to replay the game (i.e., the 7km/h and 9km/h speeds have induced more favorable user perceptions than the 5km/h speed). Further implications of the findings are discussed.

The goal of this study is to compare entrepreneurial orientation of both countries' students and to compare the effect of individualism on developing entrepreneurial orientation of both countries. In order to achieve this goal, this study will conduct two analysis. Firstly, the comparative study on entrepreneurial orientation of both students will be implemented by conducting F-test and t-test. Secondly, the regression analysis between an independent variable - individualism - and dependent variables - innovativeness, internal locus of control, and entrepreneurial orientation - will be conducted in order to compare the effect of individualism on developing entrepreneurial orientation. Prior to implementation of two analysis, this study has implemented the survey to Korean and Chinese university students to estimate entrepreneurial orientation and a cultural variable to influence entrepreneurial orientation. The question of survey is divided into two parts - individual entrepreneurial orientation including internal locus of control and innovativeness and a cultural variable, individualism. As other precedent comparative studies of Chines and Korean potential entrepreneurship concluded, Chinese students have shown higher entrepreneurial orientation than Korean students. However, on the contrary to prior studies on cultural factors and entrepreneurship, only Chinese students' entrepreneurial orientation is influenced by individualism. Any dependent variables of Korean students were not affected by individualism variable.

The main purpose of this comparative study is to analyze the impact of uncertainty avoidance on the potential entrepreneurship of five developing countries through results of survey implemented to under- and postgraduate students of five developing countries such as Cambodia, Mongolia, Nepal, Peru and Rwanda. Futhermore, it is another purpose to compare the results of respondents by gender and scrutinize what impacts of the uncertainty avoidance have on male and female students' entrepreneurial orientation. First of all, the survey was conducted to under- and postgraduate students of five countries. Questions of the survey were composed of three parts: Locus of Control and Innovativeness for the individual entrepreneurial orientation and Uncertainty Avoidance for the cultural variable. The result of this study shows that the variable of entrepreneurial orientation is getting higher when Uncertainty Avoidance variable is becoming higher. On top of that, this is shown even in the gender comparison. It is the totally different result from precedent studies that shows correlation of entrepreneurship and culture. On the other hand, men's entrepreneurial orientation of five countries higher than women's according to the gender comparison.

The convergence of telecommunications and broadcasting is representative of many innovative technologies in the digital environment. It has recently been emphasized as an alternative solution to overcome the on-going saturation of the telecommunications and broadcasting markets. Despite this effort, however, growth of the market and its related services cannot reach prior expectations due to lack of understanding on the real user-end. Telecommunications technology used to serve its instrumental purpose and broadcasting services usually support entertainment functions which in themselves have an inherent value. Our research questions what factors influence users' attitude and decision-making when it comes to using telecommunications-broadcasting convergence services. The research model of this paper proposes intrinsic motivator focusing on hedonic value, extrinsic motivator having utilitarian values, and perceived control as internal and external conditions. To verify our model empirically, we selected the DMB technology which is a good example of distinctive telecommunications-broadcasting convergence service.

This study applied self-determination theory to investigate the relationships between volunteers' perception of supervisors' autonomy support, volunteering motivation, and persistence intentions among collegiate students. Collegiate volunteers(n=515) involved in volunteer activities completed measures of supervisors' autonomy support, 5 forms regulation, and persistence intentions. Bivariate correlations indicated that volunteer motivation demonstrated an ordered pattern of relationships, such that adjunct points along the regulatory continuum would be more positively associated with on another than distal points. Analyses using structural equation modeling revealed that supervisors' autonomy support was positively related to more autonomous motivation(intrinsic motivation and identified regulation), while was natively associated with amotivation. Amotivation was negatively related with persistence intentions, and more autonomous motivations(intrinsic and identified) predicted grater intentions to continue with volunteer activity for next 6 months. The findings are discussed in light of the self-determination theory.

Recently, as the personal broadcasting industry has grown rapidly, interest in personal braodcasting platform companies, creators, and contents is increasing. In addition to the quantitative growth of the private broadcasting industry, related research is also increasing, but there is a lack of research on the viewer side. In this study, we applied the Hedonic-Motivation System Adoption Model (HMSAM) to derive the viewing motivation factors from the intrinsic aspects of personal broadcasting users. Also, we analyzed the difference of viewing motivation factors by classifying the types of personal broadcasting contents. As a result of the analysis, extrinsic and intrinsic factors of the users except "control" has a significant influence on the viewing intention and immersion. Also, it was verified that the influences on the viewer's immersion were different according to the content type. Finally, various theoretical and practical implications are presented through the results of this study.

1987년의 블랙 먼데이 이후 많은 연구는 내재적(內在的) 가치(價値)와 상관없는 주가변동성(株價變動性), 즉 '노이즈'거래와 투기적 거래에 의한 주가변동성을 감소시킬 수 있는 방안을 강구하기 위하여 주식시장의 미시적 구조문제에 관심을 가져왔다. 정부기관이나 증권거래소에서 행해진 연구에 의하면 신용규제(信用規制)와 더불어 거래제동시스템을 하나의 해결책으로서 제시하였다. 그러나, 신용규제에 대해서는 많은 실증적 연구가 이루어진 반면, 거래제동시스템의 효과에 대해서는 주식시장에서의 실무적인 경험부족으로 상대적으로 극히 미미한 실정이다. 또한 거래제동시스템의 도입이 주식시장의 주가변동성을 감소시키는 효과가 있는 지에 대한 이론적 분석도 학자간에 의견이 분분하다. 본 연구는 한국증권시장에서 가격제한폭제도(價格制限幅制度)가 주가의 변동성을 감소시키는 효과가 있는 지에 대한 보다 신뢰성있는 실증적 증거를 제시하고 있다. 한국증권시장에서의 가격제한폭제도는 주가수준에 따라 개별주식별로 가격제한폭비율이 다르기 때문에, 가격제한폭제도가 주가변동성에 미치는 효과를 분석하는데 있어 가격제한폭 이외의 다른 요인을 통제하는 것이 가능하다 본 연구에서는 가격제한폭비율이 높은 포오트폴리오와 가격제한폭비율이 낮은 포오트폴리오를 구성하여 두 포오트폴리오 간에 주가변동성의 차이가 있는지를 비교하였다. 본 연구의 결과는 가격제한폭제도가 주가변동성을 줄여주는 긍정적인 효과가 있다는 것을 강하게 보여주고 있다.

Although it has been studied for a long time in various disciplines, most of control theories remain being developed by analyzing relatively simple tasks. Even recent research on control of information systems development explains only a small part of control phenomena observed in the real world projects. This research focuses on identifying and analyzing the concepts and structures in order to make them useful for understanding and explaining control of information systems development comprehensively This investigation utilizes the complementary relationship between views on control from organizational and economic perspectives. A conceptual framework developed by integrating previous research on control allows us to analyze the development of information systems for control purposes. The results of discussion about control mechanisms and network can be used as guidelines for designing control systems in real projects. Analysis of control networks shows that control of development projects requires quite complex networks intertwining a variety of controllers and controlees. The results of this research are expected to contribute to correcting the unbalanced status of IS research which has emphasized too heavily on planning and implementation, and deepening and widening our understanding about controlling development projects. Practitioners can use the results as guidelines for designing control mechanisms and networks, and get alerted by them about the agency risks inherent in outsourced developments.
