This paper examines a simultaneous determination of corporate control mechanisms, and its effects on firm performance. The corporate control mechanisms considered include the following; insider shareholding, institutional shareholding, the board of directors, dividend policy, and capital structure. This paper applies a simultaneous equation methodology and investigates the interdependence among the corporate control mechanisms. In the first part, the paper finds that firm-level variations of control mechanisms are large across time although average variations are relatively small. These variations are related to one another, which is confirmed by Granger causality test based on dynamic panel autoregression model. More specifically insider shareholding, institutional shareholding and outside director ratio cause each other. With regard to interdependence among the control mechanisms, 2SLS(two stage least squares) regression results show that insider shareholding and institutional shareholding are substitutes while institutional shareholding acts as complements to the ratio of outside members in the board of directors. Then in the second part, the paper examines the relationship between firm performance and corporate governance. Firm performance, measured by Tobin's Q, has a positive association with leverage ratio while that has a negative relation to outside director ratio. This suggests that there may be a room for reforming corporate governance in Korea. Specifically it is necessary to enhance the independence of the outside directors.

According to the recent statistics of the National Industrial Security Center, about 80% of the confidential leak are caused by former and current employees in the case of domestic confidential leak accidents. Most of the information leak incidents by these insiders are due to poor security management system and information leak detection technology. Blocking confidential leak of insiders is a very important issue in the corporate security sector, but many previous researches have focused on responding to intrusions by external threats rather than by insider threats. Therefore, in this research, we design an internal information leak scenario to effectively and efficiently detect various abnormalities occurring in the enterprise, analyze the key indicators of the leak symptoms derived from the scenarios by using data analytics and propose a model that accurately detects leak activities.

본 연구는 기업의 기술 유출 및 특허 침해라는 정보 보안 문제 발생 시, 브랜드 기업의 시장 지위에 따라 가해 및 피해 기업에 대한 소비자 반응이 달라질 수 있다는 점에서 착안하였다. 같은 예로 대한민국 국가대표 축구팀이 약팀과의 경기에서 졌을 때, 일부는 경기력을 비난하지만, 일부는 선수 부상, 날씨, 시차 적응 등 상황이 불리했음에도 잘 싸웠다고 평가하는 경우가 있다. 이처럼 어떤 부정적 결과 대해 사람들은 각자 다른 평가를 한다는 맥락에서 기술 유출과 특허 침해와 같은 정보 보안 문제가 발생한 기업에 대해 소비자 인식과 태도는 다르게 나타날 수 있다. 이와 같이 소비자 관점에서 기대와 실제가 불일치한 지각과정을 설명하는 심리적 메카니즘에는 동화-대조 효과가 있다. 본 연구는 기술 유출 및 특허 침해에서 일어나는 소비자 동화-대조 효과를 심리학의 귀인 이론을 통해 설명하고, 이 때 사람들의 귀인 방향이 브랜드 명성이 높을 때와 낮을 때, 기술 유출 경로가 내부자일 때와 내부자가 아닐 때에 나타나는 소비자 반응을 확인하고자 한다. 또한, 이로써 나타나는 소비자 반응을 귀인 이론의 방향성과 메커니즘을 통해 설명하려 한다. 동화-대조 효과에서 나타나는 귀인의 방향성과 소비자 반응 관계를 분석한다면, 추후 기업의 R&D와 기술 개발 전략, 지적 재산권 침해 이후 사태에 대한 대응과 수습에 가이드를 제공할 수 있을 것이라 기대한다.

Generally, information breach incidents are thought to be caused by external hackers. However, both direct and indirect information breach incidents by insiders are more frequent than by external hackers. It also accounts for more than half of the total information breach, so it should be prepared against insider breach. In this study, based on General Deterrence Theory(GDT) and Rational Choice Theory(RCT), we integrated the risk sensitivity and situational anxiety, which were studied in the field of traffic psychology to construct research model. Result of analysis shows that the impact of risk perceptions on the severity and certainty of perceived punishment was not statistically significant, but perceived benefits, situational anxiety, and severity and certainty of perceived punishment were found to influence the information breach intention.

This study presents the effects and phenomenological meanings of child poverty on child development by implementing in-depth interviews with 19 adults and 20 children in Korean Welfare Qualitative Panel Study and analyzing multi-dimensional categories of child poverty experiences. By focusing on relative deprivation, this study lists the insider's view on poverty experiences such as pauperization, housing, health, education, child-raising, culture, family and child's dream, and then it describes poverty experiences in a heuristic and hermeneutic way from the child's view. Findings shows that poverty experiences of childhood are associated with negative child development experiences such as trauma, deprivation of growth and opportunity, childhood adultification, intergenerational transmission of poverty and limiting dreams. This qualitative study based on the insider's view, can contribute not only to profound understandings of multi-dimensional child poverty but to identification of client based policy demand, which enables poverty policy studies expand their boundaries.

This study sets out to explore their experiences using a biographical research method and to suggest appropriate support systems for Korean women with leprosy. The data were collected through in-depth interviews with five leprous women. The following main themes were extracted from the practical experiences of leprous women over all their life-span: "encounter the divine punishment", "huge burden on a tiny body", and, "the candle to die down". These themes are listed and described in chronological order. Leprous women were forced to choose concentration hospital to survive social stigma and discrimination. In the hospital, leprous women were treated like a pest, and further deprived of their rights regarding marriage, pregnancy and child care. Until now, they still keep themselves away from society because of their ugly body even though the disease is completely gone. But they keep praying for their children's lives. Finally they accepted a life of tears and regrets and waited for death. This study offers practical knowledge and social work implications for Korean women with leprosy.

None of the recent cases of military secret leakages have leaked internal information using networks. This is because the Internet and the Intranet are physically separated, and has a difficult process when transmitting and receiving data through the Internet. Therefore, most of the leaked paths are to copy and hand over secrets, shoot and send them with a smartphone, or disclose after remembering them. So, the technology of blocking and detecting military secret leakages through the network is not effective. The purpose of this research is to propose a method to prevent information leakage by focusing on the insider behaviors, the subject of leakage, rather than the military secret. The first is a preventive measure to prevent the leakage behavior of military secrets, the second is to block suspicious access to the military secret data, and the last is to detect the leakage behavior by insiders.

This paper investigates whether managerial ownership and foreign ownership have impacts on firm value, using a sample of logistics firms listed on the Korea Stock Exchange between 2008 and 2014. In the Korean economy, family-controlled business groups, known as chaebol, constitute a unique governance system. To acquire investments from controlling shareholders, a logistics firm is likely to be included in family-controlled business groups. Since reform of the governance structure of logistics firms in the South Korea enables shareholder value to be maximized, we analyzed ownership effects on firm value using pooled ordinary least squares. Empirical results showed that there was a significant positive relation between managerial ownership and firm value. This study also found that there was a significant positive relation between foreign ownership and firm value. We thus show that both managerial ownership and foreign ownership can protect shareholders by positively affecting firm values.
