냉전 종식 후에도 동북아시아지역의 불안정 상황은 여전히 지속되고 있다 특히 핵군비와 관련하여 역내 각 국의 동향은 매우 민감한 상태이다. 이런 면에서 이 지역의 비핵지대화는 이 지역의 불안요인에 대한 안전보장 장치가 될 수 있다. 이해 당사국들이 대체로 소극적인 태도를 보이고 있기는 하나, 객관적 상황은 비핵지대화 논의에 유리하다. 논의를 본격화하기 위해서는 첫째, 핵보유국들의 비보유국들에 대한 소극적 안보 약속, 둘째, 핵보유국 상호간의 핵 선제 불사용 합의, 셋째, 핵보유국의 핵감축 의지 표명, 넷째, 일본의 핵투명성 제고 등의 충족이 요구된다. 현재까지 논의되고 있는 구상들로는 북한 핵문제에 대한 우려가 한창 고조되던 당시에 거론되었던 한반도 비핵지대화안, 동북아 비핵지대화안, 제한적 비핵지대화안 등이 있다. 5개 핵보유국들의 협조가 없는 한 비핵지대의 실현은 어렵다. 또한 역내에 3개 핵보유국을 가지고 있는 동북아 지역의 특성에 비춰 비핵지대화의 효과를 높이기 위해서는 첫째, 집단안보라는 보다 큰 틀을 전제로 하는 접근이 필요하며, 둘째, 핵보유국들의 거부반응을 괴려한 점진적 방식의 채택이 요구된다. 그러나 무엇보다도 역내 국가들 간의 신뢰 조성 및 평화와 안정의 증진이 우선해야 하며, 그 후 지역국가들 스스로의 주도로 논의를 이끌어 나가야 할 것이다.

This study examines the effect of managerial ownership on the value of firms' cash holdings. According to the management entrenchment hypothesis, managers have incentives to make decisions that can undermine shareholders' value for their own private interests. In this situation, as the managerial ownership increases, investors may evaluate that the cash held by the company may be utilized inefficiently and the value of the cash holdings may decrease. On the other hand, based on the incentive alignment hypothesis, the value of cash holdings may increase as investors perceive cash holdings to be effectively used to increase corporate value as managers' interests are in agreement with shareholders. Empirical results show that the value of cash holdings decreased as managerial ownership increased. This study finds a contribution in that it presents empirical evidence on whether the cash held by the company is differentially evaluated according to the level of the managerial ownership.

This study examines what changes and impacts have brought to the corporate cash holding after the financial crisis. The main findings can be summarized by two parts. First, the recent high increase in cash holding is only found in few companies, meaning that the level of the overall ratio has not risen. Second, Korean companies tend to have a higher ratio of cash holding when they have more uncertainty about their business performances. The higher the uncertainty in overall business performances also has some effects on the cash holding patterns of the Korean companies.

Clostridium perfringens is both a ubiquitous environmental bacterium and a major cause of human gastrointestinal disease, and C. perfringens food poisoning ranks among the most common gastrointestinal diseases in developed countries. 120 isolates of C. perfringens were obtained from food-poisoning outbreaks in 2013~2014, Gyeonggi-do. Using PCR, all 120 isolates were identified as C. perfringens type A. Of the tested isolates, 49 isolates carried the cpe gene, 71 isolates carried the cpb2 gene. The outbreak cases of cpb2 and cpe /cpb2 genes were 7 and 7, whereas the outbreak cases of cpe-gene were 2. The epidemiological relationship between C. perfringens isolates has previously been investigated chiefly by pulsed-field gel electrophoresis (PFGE) and multi-locus sequence typing (MLST). The genetics relatedness of the isolates raged from 53.5-100% and 75 district PFGE type were observed. The PFGE results revealed a wide genetic diversity among the 64 cpb2 carrying isolates (except 7 isolates), while 46 cpe-carrying isolates (except 3 isolates) showed a high genetic similarity. The MLST analysis revealed that 14 cpe isolates (cpe-chromosomal isolates) belong to a distinct cluster that is significantly distant from all the other cpb2 isolates (cpe-plasmid carrying and cpe-negative isolates). The isolates carrying a cpb2 appear to be rarely related, and are more variable than chromosomal cpe isolates. The results suggest that the cpe-positive outbreak isolates showed close genetic relation, whereas the cpb2-positive isolates revealed a wide genetic diversity.

This study investigates the following important financial questions using entertainment enterprises: 1) how does cash reserve affect a firm's financial value? 2) what factors influence the level of cash retention of a firm? For empirical tests, we use accounting and financial data of entertainment companies listed in the KOSPI and KOSDAQ markets for a long-term time period covering from 2000 to 2018. The main findings of this paper are as follows: First, entertainment companies maintain higher level of cash holdings compared to non-entertainment companies. Second, the cash holdings of entertainment enterprises have positive influence on firms' financial value. Third, among various firm characteristics known for affecting the cash holdings level, leverage and profitability exhibit strong relationships in entertainment enterprises. Entertainment firms with lower leverage and higher profitability tend to reserve more cash inside them. These findings suggest that entertainment companies are highly valued by stock market participants as having prospective opportunities, thus, firms with sufficient cash holdings tend to have higher firm value. In addition, these findings imply that cash in entertainment enterprises functions as a substitute for debts and the cash holdings are less likely driven by agency problems.

This paper examines whether investors have adapted to the venture capital(VC) investment style. VC firms invest in privately held companies and generate returns by selling them after the lock-up period expires. We analyze the impact on stock prices before and after the lock-up period expiration, and compare the Cumulative Abnormal Return(CAR) between the past period(2015-2017) and the recent period(2020-2022) to investigate the effect of the second venture boom. The main findings are as follows. First, unlike in the past, stock price returns around the lock-up period expiration have been lower than the KOSDAQ index in recent years. Second, the impact on stock prices is significant for both 1-month and 12-month lock-up periods. Specifically, it is confirmed that stocks held by venture capital and professional investors with a 1-month lock-up period respond in advance to their information after the second venture boom. Finally, we find that there is a difference in CAR depending on whether or not the company received VC investment after the second venture boom. Based on our findings, we suggest that VC firms need to revise their exit strategies to improve performance. This includes finding ways to reduce information asymmetry and fees, as well as developing strategies to mitigate market volatility. Additionally, the current lock-up period for VCs should be reconsidered as it may increase the risk of stock price decline. We recommend that the government revise the scope and duration of lock-up periods to protect investors after IPO.

The purpose of this study is to solve the limitations that the information security manager of company should recognize the personal information of all employees. In this study, we propose efficient personal information retention status management system to minimize information retention status of personal information and department by information security manager and departmental information security officer. To do this, we study the method of transferring the check result from the PVA system to the efficient personal information retention management system, also study ways to minimize the amount of personal information we hold. It is possible to minimize the possession of personal information by changing the one channel method managed by the information security administrator of the existing PVA system to the two channel method so that the information security manager and the information security officer can manage it.
