Background and main issue: In the Korean insurance market, an outstanding issue is the decrease of margin of risk ratio. This affects the solvency and profitability of insurance companies. Insurance medicine, which has been developed in Western countries, is so-called medical risk selection or medical underwriting. Medical risk selection is based on clinical follow-up study and mortality analysis methodology. Unfortunately, there have been few clinical follow-up studies, and no intercompany disease analysis system is available in the Korean insurance market. In practice, we use underwriting guidelines, which were developed by some global reinsurance companies. However, these guidelines were developed under clinical follow-up studies performed abroad. So, we cannot rule out underestimation of excess mortality factors such as mortality ratio, excess death rate, and life expectancy. It is necessary to perform medical assessment in claims administration. Comparing the insured's statement by medical records with products' benefit according to this procedure, we can make sound claim decisions and participate in the role of sound underwriting. We can call this scientific procedure as the verification of medical claims review. Another area of medical claims review is medical counsel for claims staff. Result: There is another insurance medicine in addition to medical risk selection. Independent medical assessment by medical records of insured is medical claims review. Medical claims review is composed of verification and counsel.

This study's aim was to explore the relationships among consumers' perceived risk, trust, and familiarity with products made in China. We invited 489 Korean adult consumers, who had purchased products made in China earlier, to take part in this investigation. Data analyses were conducted using a reliability test, confirmatory factor analysis, and structural equation modeling (SEM) with SPSS ver. 21.0 and AMOS ver. 21.0. We assumed that the perceived risk could be classified into four types: financial, performance, psychological, and social risk. The empirical verification through SEM indicated that all four types of the perceived risk represented a negative influence on the trust. Further, only the financial and psychological risks were significant when consumers were not familiar with products made in China (novice); in contrast, the experts (consumers familiar with products made in China) showed that the performance and social risks were effective. Finally, we found that there was a moderating effect of familiarity on the relationship between three types of perceived risk, namely financial, performance, and psychological risks, and trust, but the social risk was not affected. The results of this research should help us to understand the consumers' risk perception of imported goods and to formulate criteria on the basis of which the consumers evaluate these products. This research can help companies, particularly those in China, to formulate market strategies effectively when they enter a foreign market such as Korea by exploring the influence of the perceived risk on local consumers' purchasing behaviors as well.

이 연구는 금융시장 빅데이터인 개인신용정보와 주택시장 빅데이터인 주택실거래데이터를 연계하여 LTV 뿐만 아니라 CoLTV 지표를 추정하여 임대차주의 상환위험을 분석하였다. 분석결과, LTV로만 상환위험을 파악하는 경우, 전세임대차주보다 월세임대차주의 상환위험이 더 컸으나, CoLTV를 이용하면 전세임대차주의 상환위험이 더 크게 나타났다. 이를 통해서 주택담보대출이 있는 전세의 임대차주의 상환위험이 높아, 임차인의 보증금에 손실이 발생할 가능성이 있으며 이를 위해 CoLTV지표를 통한 위험관리, 전세금반환보증과 같은 보증제도를 활성화할 필요가 있음을 밝혔다. 또한 임대계약의 특성과 차주의 개인 특성에 따라 임대차주의 상환위험에 미치는 영향이 다르게 나타남에 따라 임대차주의 개별적 특성을 충분히 고려해야 위험을 관리해야 함을 밝혔다. 이 연구는 개념적으로 논의되던 CoLTV를 금융빅데이터인 개인신용정보와 주택빅데이터인 주택실거래 정보를 결합하여 산출하였으며, 이를 통하여 임대차주들의 계약 및 개인적 특성별로 상환위험을 분석하고 시사점을 제시했다는 점에서 의의가 있다.

본 논문은 우리나라 노동시장에서 1990년대에 소득 변동성이 증가한 양상을 실증적으로 추정하고, 이러한 소득 변동성의 증가가 자본시장의 개방에 의해 설명될 수 있는지 분석하였다. 소득 변동성 추정에 있어서는 패널 자료가 아닌 반복 횡단면 자료에 간단한 계량모형을 적용하여 임금소득의 일시적 변화와 항구적 변화에 대한 분산을 추정하였다. 1990년대 소득 변동성의 증가 추세는 1992년 주식시장 개방을 필두로 한 우리나라 자본시장 개방과 시기적으로 일치하는 것으로 보이나, 산업 차원에서의 횡단면 분석에 의하면 양자간의 인과관계는 강하지 않은 것으로 추정된다. 다만 외국인 직접투자의 경우 고학력 근로자의 일시적 소득 변동성은 줄이는 효과를, 저학력 근로자의 일시적 소득 변동성은 증가시키는 효과를 갖는 것으로 추정되었다. 이와 같이 근로자 유형별로 비중립적인 효과를 갖는 것은, 자본과 기능의 보완성에 따른 효과로 판단된다. 한편 일시적 소득 변동성이 자본시장에서 충분히 분산될 수 없다면, 이러한 외국인 직접투자의 비중립적 효과는 "임금소득의 변동성"이라는 측면에서 근로자 유형별 복지의 격차를 유발시킬 가능성이 있다고 판단된다.

Purpose: This study would measure the users'perceived overall quality level of A automobile Company, which has leading market power in the domestic automobile market and analyze the causal relationships in the quality value process Model to quality capability, customer value and loyalty based on that. Especially, this study would analyze the relative impacts of the users'perceived risks appearing in the quality value process model of the formation of Quality Factors(QF), Customer Value(CV), and Customer Loyalty(CL) and analyze the moderating effect of the causal relationships among the components. Methods: For an analysis of causal relationships connected to QF, CV, and CL of the customers who purchased Auto manufacturer A's automobile users, 179 users who used within 3 years were utilized as samples for the analysis. As for QF, based on the Garvin(1988), the QF of automobiles were redesigned. For a structural equation analysis of the entire research model, the PLS(S(Partial Least Square) model was utilized. Results: As a result of an analysis, R2 of CV and CL was 0.652 for CV and 0.664 for CL, which was a very stable Goodness of fit. As a result of an analysis of the hypotheses of QF and CV, automobile performance, conformance, aesthetics, serviceability, and durability. In addition, it turned out that the perceived risk had a moderating effect on convenience, service availability, and perceived quality. Conclusion: This study found that the perceived quality risk appearing among automobile users had negative effects on the quality value process model to QF, CV and CL. In contrast, there were factors not affecting the users'quality value process in spite of the perceived risk. These factors can suggest important managerial implications in that they can be utilized as Auto manufacturer A's market-dominant strengths.

The purpose of this study is theoretical research on risk. The research is focused on systematic risk. Chapter I is objective of this study, Chapter II includes definition and measurement of risk. Chapter III introduces attitudes toward risk and classification of risk. Chapter IV discusses Portfolio theory, Capital market line and Shape and Lintner model The objective of firm is assumed to maximize its value. In a world of uncertainty, value is not determined by earnings alone, the degree of risk involved with the streams of earnings. Financial manager has to consider the risk in order to maximize the value of firm. Total risk can be classifier into two parts : Systematicrisk and unststematic risk by Sharpe. Systematic risk is important because investors can't diversify it. Blume and Jensen measured f and they testified that the f is stationary over the time For further study, Korean stock mark has to take emperical study about $\beta$ and its stationarity.

The liquidity risk is defined as an additional risk in the market due to the timing and size of a trade. A recent work by Cetin et ai. (2003) proposes a rigorous mathematical model incorporating this liquidity risk into the arbitrage pricing theory. A practical problem arising in a real market application is an estimation problem of a liquidity cost. In this paper, we propose to estimate the liquidity cost function in the context of Cetin et al. (2003) using the constrained least square (LS) method, and illustrate it by analyzing the Kellogg company data.

Since Korean government has implemented the "Number Portability System" in the domestic mobile communications market, mobile communication companies have been striving to hold onto existing customers and at the same time to attract new customers. This paper presents a competing risk model that considers the characteristics of a customer in order to predict the customer's life under the "Number Portability System." Three competing risks considered are pricing policy, quality of communication, and usefulness of service. It was observed that the customers who pay more are less sensitive on pricing policy younger people are less sensitive than older people to the quality of communication and women are more sensitive than men to the degree of usefulness of service. We expect that the result of this study can be used as a guideline for effective management of mobile phone customers under the Number Portability System.

Credit derivative is one kind of arrangement which allows one party to transfer, for a premium, the defined credit risk, computed with reference to a notional value, of a reference asset which may or may not owned by one or more other parties. Credit Default Swaps(CDS) have existed since the early 1990s, but its use has become increasingly popular over time. CDS is the fastest growing segment of the privately negotiated derivatives business as many firms depend on it to efficiently manage the financial market risks inherent in economic activities. The diversification function is especially important for active CDS market participants as banks. CDS banks can achieve their loan portfolio diversification which provides them with increased capacity to expand their lending.
