The purpose of this study is to study internal and external factors affecting entrepreneurial intention of korean professional soldiers who are supposed to retire less than one year. Another main focus of this study is to find out whether there is mediating effect of entrepreneurial support programs for entrepreneurial intentions. In this research, data were collected from 361 officers and non-commission officers who are scheduled to retire from the military within 5 months to one year after at least 10 years of military service. The collected data were analyzed by SPSS using the regression analysis method. In this study, we found that internal factors did not positively affect entrepreneurial intentions, however, external factors positively affected entrepreneurial intentions. It was also found that entrepreneurial support programs played important role as moderating variables between social perceptions toward entrepreneurs and their entrepreneurial intentions. Based on these findings, implications of research implications are discussed, and recommendations for future research were provided.

In this paper, we analysed RSS characteristics by external factors and presented an efficient algorithm for real-time location tracking and its hardware system. The proposed algorithm enhanced the ranging accuracy using Kalman Filter based on the RSS DB. The location tracking system that consists of the tag, AP(Access Point), a data collector(Data Receiver) with IEEE 802.15.4(ZigBee) network environment, and location tracking application that reveal locations of each tag is implemented for the test environment. The location tracking system presented in this paper is implemented with MSP430 microprocessor manufactured by TI(Texas Instrument), CC2420 RF chipset and the location tracking application. With the results of the experiment, the proposed algorithm and the system can achieve the efficiency and the accuracy of location tracking with the average error of 19.12cm, and its standard deviation of 5.31cm in outdoor circumstance. Also, the experimental result shows that exact tracking of position in indoor circumstance cannot achieve because of vulnerable RSS with external circumstance.

본 연구는 무선인터넷 컨텐츠 중 가장 많은 비중을 차지하고 있는 모바일 게임의 고객 충성도 형성요인을 고찰하였다. 모바일 게임 산업은 그동안 각 이동통신사에 종속된 게임업체들이 게임 컨텐츠를 공급함으로써 게임업체에 지속적인 충성도를 가지는 고객을 확보하기가 어려웠다. 그러나 이제 무선망 개방과 더불어 이동 통신회사와는 관계없이 자유롭게 무선인터넷 접속이 가능해짐에 따라 많은 변화가 예상된다. 즉, 시장의 장벽이 사라지게 되어 모바일 게임업체들 간의 경쟁은 더 한층 심화될 것이며, 결국 안정적인 고객을 확보한 몇몇 기업만이 살아남게 될 것이다. 따라서 본 연구에서는 모바일 게임의 충성도 형성에 영향을 미치는 변수들에는 어떠한 것이 있는지 조사해 보고자 한다. 기존의 온라인 게임이나 컴퓨터 게임의 충성도에 관한 연구들을 참조하여 모바일 게임만의 특성을 고려한 연구모형을 설정하였다. 먼저 모바일 게임의 충성도에 영향을 미치는 요인을 게임의 내적 요인과 외적 요인으로 구분하였다. 모바일 게임의 내적 요인으로는 게임 컨텐츠 자체의 참신성, 조작용이성을, 게임 외적 요인으로는 브랜드 인지도와 사회적 상호작용성을 선정하였다. 이러한 변수들이 모바일 게임 만족도에 영향을 미치고 또 이 만족도가 모바일 게임에 대한 고객 충성도로 이어진다는 모델과 가설을 제시하였다.

The purpose of this study was to verify the effect of leisure barriers on participation type of leisure activities in disabled in Korea. The raw data variable of '2014 Disabled People Status Survey' were categorized as internal/external barriers and leisure type. The type of participation in leisure activities according to general characteristics was performed descriptive statistics and Pearson correlation and multiple regression analyses were conducted to examine the correlation and causal relationships of types of internal/external constraints and leisure activity participation. The element that effects on a level of current passive leisure activity type, it resulted as two variables of internal barriers, three variables of external barriers, the explanation ability was analysed as to 48%. it resulted as two variables of internal barriers, five variables of external barriers in active leisure activity, five variables of external barriers, the explanation ability was analysed as to 29%. Therefore, based on various constraints of disabled people in Korea, a plan should be prepared to encourage participation of leisure activity, and systematic review and detailed study on two academic subjects related to leisure and disability should be done.

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.

파괴인성은 내적 및 외적요인 등에 의해 변할 뿐만 아니라 조직의 불균질성 때문에 소성둔화 및 파괴가 균일하게 일어나지 않으므로 이에 대응한 파괴인성을 선택하여 평가함이 가장 중요하다. 또한 기계의 고속화에 따라 충격적인 하중에 의한 동적파괴의 문제가 중요하게 되고 이에 따라 동적파괴인성 평가법의 확립에도 많은 연구가 필요하다. 한편 피로균열진전거동의 실험에는 많은 시간과 인적 노력이 필요로 하며 이러한 문제점을 해결하여 균열진전 측정의 정밀화 및 효율성을 높이기 위해서는 컴퓨터의 이점을 적극적으로 응용할 필요가 있다.

This study examined the factors affecting the team identification of professional baseball fans. The factors were divided into the fan factor, game factors, and other factors. For the analysis, two investigators visited stadium three times in total and a total number of 297 spectators were sampled using a convenience sampling method from three baseball teams. For the fan factor, a fan who began supporting his/her team from childhood or after childhood was used as a dummy variable. The interaction effects between the fan factor and other variables were investigated to offer a stereoscopic understanding about the role of kids marketing. In addition, three game factors and four non-game factors were analyzed. The results regarding fan variable and interaction effects were obtained. Fans from their childhood have much stronger team identification, and show interaction effects with the players. Regression analysis revealed player, promotion and fan service, price, and regional connection to have positive relations with team identification. This study is especially meaningful in a sense that it has proposed positive results regarding marketing to children, and the results will contribute to both the academic field and the industry.
