A project manager of construction project must analyze risks which might happen during the construction phase and prepare a restoration method against the risks in order to get the successful project's accomplishment. Insurance is a representative kind of risk transfer method and an institution which prevents damages of the insured. In spite of increasing the ratio of construction insurance policy in the construction industry, project managers have regarded the insurance as a formal action in the budget through insurance companies' guides. These aspects make them not be able to valuate the reasonableness of premium rate and the real amount of the risks. This thesis is to present an improved method of construction insurance contract. Firstly, the status of the current construction insurance system have been anlyzed and the problems have been deducted. Secondly the development direction against the problems is presented in the research. Lastly, the procedure model is proposed for acquiring the resonable premium rate of insurance.

In this paper, a surplus process with investments is introduced. Whenever the level of the surplus reaches a target value V > 0, amount S($0{\leq}S{\leq}V$) is invested into other business. After assigning three costs to the surplus process, a reward per unit amount of the investment, a penalty of the surplus being empty and the keeping (opportunity) cost per unit amount of the surplus per unit time, we obtain the long-run average cost per unit time to manage the surplus. We prove that there exists a unique value of S minimizing the long-run average cost per unit time for a given value of V, and also that there exists a unique value of V minimizing the long-run average cost per unit time for a given value of S. These two facts show that an optimal investment policy of the surplus exists when we manage the surplus in the long-run.

대리운전업체에 소속되어 있는 대리운전자가 대리운전 보험에 가입한 경우, 보험료는 대리운전자가 직접 부담하는 경우가 대부분이나 계약당사자인 보험계약자는 대부분 대리운전업체로 되어 있다 보니 약관내용에 대해 제대로 설명을 듣지 못했다는 이유로 보상범위 등을 둘러싼 분쟁이 발생하는 경우가 많다. 본고에서는 차주가 동승하지 않은 채 대리운전자가 차량을 운전하던 중 발생한 사고를 대리운전보험에서 담보하는 '대리운전 중 사고'로 볼 수 있는지 여부를 다룬 사건을 소개하고자 하는데, 쟁점 가운데 약관의 설명의무와 관련 사항을 일부 언급하고 있어 동 내용을 살펴보고 나아가 약관 설명의무의 법적 성격 및 유사 분쟁사례 등을 개관하고자 한다.

Currently, Korea government has strongly recommended the storm and flood insurance system to reduce the damage caused by natural disasters. The storm and flood insurance operated by private insurance company is the type of policy insurance. and is supervised by Minister of Public Safety and Security. It is the advanced disaster management system which is able to protect the public interests through unexpected natural disaster by assisting some part of the insurance premium from a central or local government. The main purpose of the present investigation is to build the insurance object GIS DB which should be necessary to calculate the premium rate in the map for storm and flood insurance, and also, to perform GIS analysis. The service model in this study is aimed to general single house, apartment and green house. The service management plan targeting the whole country has been investigated in terms of building DB and service operation.

An assumption for fractional ages should be made to obtain the net premium of the whole life insurance payable at the moment of death based on the life table. Most existing studies adopt the assumption of the uniform distribution(UDD) for the fractional ages. However, as seasonal changes may frequently lead to the deaths of elderly people, it is questionable whether the assumption of the uniform distribution is the most appropriate one for the entire age intervals. In this article, based on a real mortality data set, the appropriateness of UDD assumption for the entire age intervals is examined. And then we propose a more suitable model for fractional ages. We analyze the effect of UDD assumption through the net premium and the corresponding risk when the true distribution for the fractional ages is not uniform.

One of the challenging tasks of the National Health Insurance Corporation(NHIC). the only public insurance institution administrating the Korea's compulsory national health insurance(NHI) system, is to make those NHI beneficiaries who fail to make a scheduled monthly premium payment to pay. For this purpose, the NHIC has been using a measure known as 'Benefit Limit Measure(BLM)' in which those who miss premium payment for six or more month's in total are classified as 'late payer' and are sent warnings and late payer status notices. If the late payers fail to make a full payment of missed premiums even after receiving the written notices, the NHIC can order a temporary seizure of the late payer's property until all missed premiums plus interest are paid. Recently, the BLM has been criticized by the public of its cruel nature, and its effectiveness has been questioned because no empirical evidence has been collected. In this study, the authors using the NHIC data set attempted to analyze the effectiveness of the BLM. Those late payers for whom the BLM was administered were compared to those not in terms of the likelihood of paying missed premium payments with a series of logistic regression analyses models. Data analyses results showed that the likelihood of paying one or more month's unpaid premium of the former group was 14 to 46 times higher than the latter. It, however, was also found that the BLM was only effective to make no more than 12% of the late payers to pay at all. Based on the study findings, the authors made a few recommendations regarding the BLM.

Multiple-life policies pay a benefit on the first death or the last death among the group of lives. In practice, the future lifetime random variable of policy holders has been considered to be independent, but it is more rational to take into account the correlations among the policy holders. In this paper, the Gaussian copula is applied to re ect the correlations among policy holders and then to diversify the common shock of the multiple life policies which follows an exponential distribution. Five case studies demonstrate its usefulness of using copula in calculating the premiums of the multiple-life policies including the common shock.

We use a unique survey data set of storm and flood insurance in Korea to test for adverse selection. We find systematically positive relationships between the decision to buy the insurance and the insureds' past history with, and potential for, losses from natural disasters. The empirical results suggest that consumers with higher loss rates will be more likely to purchase the insurance. This highlights the importance of considering the detailed features of insurance contracts, such as an improvement in the current insurance premium assistance program as the government amends its current policies regarding storm and flood insurance and disaster relief program.

Freight car accidents occur frequently and have a high mortality. In this reason, freight can insurance fee has been raised drastically. But speeding and overloading of trucks are still not decreased. We need to consider a measure about voluntary safe driving of truck drivers. We select UBI(Usage-Based insurance) as a measure for safe driving of truck drivers. UBI is a car insurance system and insurance fee is flexible. If vehicle drivers drive safely, insurance fee is discounted. The other way, if vehicle drivers drive dangerously, insurance fee is increased. In now, very high insurance fee for truck drivers, UBI is a effective way for leading a truck driver to safe driving. The most important thing in UBI is to evaluate truck driver rationally and accurately. In this paper, we select the reasons of truck accidents and develop driving evaluation model from multiple regression analysis and correlation analysis with accident reasons and truck accidents.

According to a research analysis of the factors which affect the medical utilization fee after an increase of health insurance benefits for patients with serious illnesses based on 225 patients over 6 months, both before and after the increase of benefits, from January, 1st, 2005 to June 30th, and also from January, 1st, 2006 to June 30th. In terms of genders, 67.8% of males were affected, whereas only 32.2% of females were effected, a much higher rate of men than women. Men also had higher rates before and after the increase of benefits. Out of 5 categories related to medication and treatment, radiation testing was the most expensive at about 5,300,000, operation fees were 590,000, and costs of other testing approximately 200,000 with the least expensive category being 120,000 for medication. By looking at the relationship between the fees and increase of benefits, medication was a hospital charge (p<0.01), injection fees were hospital charges (p<0.01), operation fees were hospital charges (p<0.01). Medication fees (p<0.01) and injection fees (p<0.01) were found to be related.
