공공교육시설 발주기관에서는 '98. 5월 건설공사비 절감방안을 수립하여 '98년 후반기부터 현재까지 추진 중이다. 이 절감방안은 공공공사에 반영토록 규정되어 있는 공사제잡비율의 인하 적용, 표준품셈 중 과다하게 계상되어 있는 노무품의 인하 적용, 소규모 공사의 통합발주를 통한 최저가입찰 유도를 주요내용으로 한다. 그러나 이 공사비절감방안은 그 시행초기부터 현재까지 공사부실과 건설업체 경영부실을 가중시킨다는 각종 민간건설단체, 정부기관 및 교육시설 발주기관의 지적과 개선요구가 있어 왔다. 본 연구의 목적은 현행 공공교육시설 공사비절감방안의 문제점을 도출하고 그 정책적 개선방향을 제시하는 데 있다.

Background: The food and food service influence the quality of life and the general health condition of older persons living in long-term care (LTC) facilities. Purchasing good food materials is a ground of good food service. In Korea, the residents in LTC facilities should pay for the cost of food materials and ingredients out of their pocket because it is not covered by LTC insurance. This study explored what factors affect the cost of food materials paid by LTC facility residents and which factor affects most. Methods: We used data from the study on out-of-pocket payment on national LTC insurance, which surveyed 1,552 family caregivers of older residents in LTC facilities. We applied conditional multi-level model, of which the first level represents the characteristics of care receivers and caregivers and its second level reflects those of LTC facilities. Results: We found that the facility residents with college-graduated family caregivers paid 11,545 Korean won more than those with less than elementary-graduated ones. However, the income level of family caregivers did not significantly affect the amount of the food material cost of the residents. The residents in privately owned, large, metropolitan-located facilities were likely to pay more than those in other types of facilities. The amount of the food material cost of the residents was mainly decided by the facility level factors rather than the characteristics of care recipients and their family caregivers (intra-class correlation=82%). Conclusion: These findings suggest that it might be effective to design a policy targeting facilities rather than residents in order to manage the cost of food materials of residents in LTC facilities. Setting a standard price for food materials in LTC facilities, like Japan, could be suggested as a feasible policy option. It needs to inform the choice of LTC users by providing comparable food material cost information. The staffing requirement of nutritionist also needs to be reviewed.

Background: Our study objectives were to evaluate the medical economics of cervical cancer prevention and thereby contribute to cancer care policy decisions in Japan. Methods: Model creation: we created presence-absence models for prevention by designating human papillomavirus (HPV) vaccination for primary prevention of cervical cancer. Cost classification and cost estimates: we divided the costs of cancer care into seven categories (prevention, mass-screening, curative treatment, palliative care, indirect, non-medical, and psychosocial cost) and estimated costs for each model. Cost-benefit analyses: we performed cost-benefit analyses for Japan as a whole. Results: HPV vaccination was estimated to cost $291.5 million, cervical cancer screening $76.0 million and curative treatment $12.0 million. The loss due to death was $251.0 million and the net benefit was -$128.5 million (negative). Conclusion: Cervical cancer prevention was not found to be cost-effective in Japan. While few cost-benefit analyses have been reported in the field of cancer care, these would be essential for Japanese policy determination.

It is well established that excessive sodium intake is related to a higher incidence of chronic diseases such as hypertension, stroke, coronary heart disease, cardiovascular disease and gastric cancer. Although the upper limit of the current sodium intake guideline by WHO is set at 2,000 mg/day for adults, sodium intake of Koreans is well over 4,700 mg/capita/day implying an urgent need to develop and implement sodium intake reduction policy at the national level. This study investigated the cost-effectiveness of the sodium intake reduction policy, for the first time, in Korea. Analyses were performed using most recent and representative data on national health insurance statistics, healthcare utilization, employment information, disease morbidity/mortality, etc. The socioeconomic benefits of the policy, resulting from reduced morbidity of those relevant diseases, included lower medical expenditures, transportation costs, caregiver cost for inpatients and income losses. The socioeconomic benefits from diminished mortality included reductions in earning losses and welfare losses caused by early deaths. It is estimated that the amount of total benefits of reducing sodium intake from 4.7 g to 3.0 g is 12.6 trillion Korean Won; and the size of its cost is 149 billion Won. Assuming that the effect of sodium intake reduction would become gradually evident over a 5-year period, the implied rate of average return to the sodium reduction policy is 7,790% for the following 25 years, suggesting a very high cost-effectiveness. Accordingly, development and implementation of a mid-to-long term plan for a consistent sodium intake reduction policy is extremely beneficial and well warranted.

Three types of warranty policies are considered. They are (1) free warranty policy for repairable products, (2) free warranty policy for nonrepairable products, and (3) rebate warranty policy. Under each warranty policy, a single sampling attribute plan with non-destructive testing is considered. A sampling plan is characterized by the sample size and the acceptance number. For each case, characteristics of an optimum sampling plan are discussed and determined, which minimize the warranty cost and the corresponding quality control cost within the assigned producer's risk and consumer's risk.

This study aims to analyze the policy change which is caused by conflicts between interest groups when the Separation of the Prescribing from the Dispensing of Drugs (SPDD) was enforced. With the theory of New Institutionalism, the reason why the policy was to be changed can be explained by the concept of property right and transaction cost. As the government did not consider the change of property right and transaction cost between actors before introducing new institution, it was hard to adapt the SPDD. Though, under the established institution, the institutional change can cause the alteration in property right and transaction cost, government just focused on the new institution's execution. Therefore, the group which suffers the loss could not accommodate to the change of institution. For this reason, the adaptation of SPDD also caused huge conflicts between doctors and pharmacists. Then, this research shows that the reason why they conflict to the some issues in the content of PSPDD and why the issues was changed with the property right and transaction cost.

본 연구에서는 스무딩된 주문정책이 리드타임, 만족율, 재고비용에 미치는 영향을 연구한다. 이를 위해 스무딩된 order up to 주문정책을 사용하는 하류업체와 make to order 방식을 사용하는 상류업체로 구성된 공급사슬을 사용한다. 스무딩을 하면 리드타임이 예상하는 바와 같이 감소된다. 그러나 스무딩에 의해 하류업체에서의 만족율이 감소하며 재고비용이 증가된다. 한편 상류업체 제조시간의 분산이 평균 제조시간보다 만족율 및 재고비용에 미치는 영향이 더 크므로, 상류업체 제조시간의 변동성을 최소화해야 한다.

As for M/G/1 queueing system, we use various control policies, with which we can optimize the system. Up to now the most widely adopted policies are N-Policy, T-Policy, D-Policy, and so on. The existing researches are largely concerned to find an optimal operation condition or to optimize the system under single policy in M/G/1 system. There are, however, few literatures dealing with multiple control policies at once to enhance the flexibility of the model. In this study, we consider M/G/1 system adopting N-Policy and T-Policy simultaneously. If one of two conditions is satisfied, then, the server starts the service. We call this Min(N,T)-Policy. We find the probability distribution of the number of customers and mean waiting time in steady state and derive a cost function. Next, we seek the $N^*$, optimal threshold under various N values. Finally, we reveal the characteristics of cost function.

A replacement policy with repair cost limit is discussed. When a system fails, the repair cost is estimated by inspection and repair is then undertaken if the estimated cost is less than a predetermined limit L ; otherwise the system is replaced. After repair, the system is as good as new with probability(l-p) or is minimally repaired with probability p. It is assumed that repair cost can not be estimated exactly because of inspection error. When the failure time follows a Weibull distribution and repair cost a normal distribution, the value of repair cost limit minimizing the expected cost rate is shown to be finite and unique.
