Background: The most important thing to strengthen primary care is to prove that the continuity of primary care is an essential area for good health outcomes. The purpose of this study is to analyze the effect of outpatient continuity of primary care on the hospitalization experience of diabetes mellitus in new diabetic patients. Methods: Using the Korean National Health Insurance Service national sample cohort (NHIS-NSC 2011-2015) data, 3,391 new diabetic patients in 2012 were selected for the study. Multiple logistic regression was performed to investigate the effect of outpatient continuity of primary care on hospitalization in new diabetic patients. Results: The outpatient continuity of primary care in new diabetic patients was measured by the continuity of care index, which showed that 69.4% (n=2,352) were high level and 30.6% (n=1,039) were low level. Patients who had high continuity of primary care at the early stage of diabetes diagnosis showed 3.49 times more likely to maintain high continuity of primary care in the second year (95% confidence interval [CI], 2.72-4.49). Patients with low continuity of primary care for 2 years from the initial diagnosis of diabetes were 2.56 times more likely to be hospitalized due to diabetes than those who did not (95% CI, 1.55-4.25). Conclusion: This study identified the need for policies to increase the continuity of primary care for new diabetic patients and could contribute to lowering the admission rate of diabetic patients if the policy for this would work effectively.

This paper develops a periodic preventive maintenance(PM) policy following the expiration of warranty. Two types of warranty are considered: renewing warranty and non-renewing warranty. Also, we consider the situation where each PM cost is an increasing function of the PM effect. We determine the optimal number of PM's before replacing the system by a new one and the optimal length of period for the periodic PM following the expiration of warranty. Explicit solutions to determine the optimal periodic PM are presented for the Weibull distribution case.

In compare with a major developed countries, Korea consumes much energy, but also eliminates much carbon dioxide. Agricultural sector eliminate much carbon dioxide than industrial sector. In Kyoto protocol, Korea needs to reduce carbon dioxide. One way to reduce carbon dioxide is utilization of biomass in rural area. This paper focus on utilization of biomass in rural area. If use 20% potential amount of biomass, it obtain 50% of TPES on agricultural sector. The condition of utilization biomass is connected with agricultural policy, environmental policy, and energy policy. And environmental restriction keep pace with economical incentive.

General replacement policy includes document-based LRU or LFU technique and other various replacement policies are used to replace the documents within cache effectively. But, these replacement policies function only with regard to the time and frequency of document request, not considering the popularity of each web site. In this paper, we present the document replacement policies with regard to the popularity of each web site, which are suitable for modern network environments to enhance the hit-ratio and efficiently manage the contents of cache by effectively replacing documents on intermittent requests by new ones.

Policy of for-profit hospitals permission has provoked debate on how to enhance health care system and medical service industry. The government says that for-profit hospitals could help improve the quality of medical care and develop medical tourism. On the other hand, Medical care related NGO insist that for-profit hospitals will not fix the existing medical problems in Korea, only create new ones. Recently, a type of for-profit hospitals emerged in dentistry and caused much trouble. Accordingly, We try to carefully look at for-profit hospitals related policy and debate.

The reliability guarantee insurance policy for parts and materials was introduced to the market in 2003. This policy indemnifies manufactures of products for the repair/failure costs, recall expenses of products and business interruption losses found to be defective by users or demand companies during the terms of guarantee and after the user acquired physical possession of the product. In this paper, owing to the nature of the policy, we propose a new rate-making system considering the type of product and industry, quality control circumstances, record of guarantee performance, and exposure.

For inferring criteria in a performance appraisal. linear programming (LP) has been utilized as an alternative to policy capturing (PC). Previous policy capturing LP (PCLP) studies were limited to the criteria of exact numerical ratings. However. under certain evaluation circumstances, a ranged rating with a lower and upper bound may be preferred over an exact numerical value. Therefore, this study introduces a new LP model that allows ranged ratings. A simple example is given to illustrate our model.
