The goal is to improve the national health level in our country. To achieve this how to manage the chronic diseases cost-effectively is very important. Population-based comprehensive Chronic Care Model approach should be arranged in the national health insurance framework. It is necessary that private health promotion services are launched in the market, but we should focus on which way of delivering preventive services can benefit in the future.

Purpose: Rapid growth of prescription drug expenditures is a problem in South Korea. The objective of this study was to assessthe contributions of four variables (therapeutic choice, drug-mix, original use, and price changes) to increases in drug expenditurespaid by the National Health Insurance (NHI) in Korea. Materials and Methods: A retrospective cohort study was conducted between January 1, 2008 and June 30, 2012 utilizing datafrom the NHI Claims Database of the Health Insurance Review and Assessment Service. The number of target drug types for finalanalysis was 13959. To analyze the growth rates of drug expenditures, this study used Fisher ideal index and the Laspeyres and Paascheindexes. Results: With the exception of 2012, therapeutic choice contributed to about 40–60% of the increase in drug expenditures everyyear, while drug-mix contributed to another 30–40%. Conclusion: The rapid growth in prescription drug expenditure was found to be largely due to drug-mix and therapeutic choiceover time. Original use had little impact on drug spending.

This study was performed to investigate the phyico-chemical characteristics of breast meat from spent hens (SP) in comparison with the same part from the broilers (BR). The moisture and crude protein contents for SP were 72.56% and 24.26%, which were lower than 75.87% and 24.64% for BR. Crude fat and crude ash contents in SP were 0.45% and 1.00%, which were higher than the BR contents of 0.41% and 0.51%. The respective L, a and b value for SP were 48.61, 2.40 and 2.42, which were lower than the BR values of 49.41, 1.45 and 3.06 respectively. The pH for SP was 5.89, which was higher than pH 5.79 for BR. The WHC for SP was 50.29%, which was lower than that of BR at 62.31%. SP scored 28.04% in the heating loss test, which was significantly higher than 19.09% for BR. The shear forces for SP and BR were 4.86 kg and 1.36 kg respectively, which meant that the texture of SP was much tougher than that of BR. Hardness for SP was 8.89 kg while that of BR was 3.92 kg indicating that the SP texture is firmer than that of BR. Oleic acid was most abundant fatty acid in both samples and was at 44.15% in SP and 27.68% in BR.

In order to determine the material characteristics of pork rinds according to the breeds, the chemical composition, color, pH, collagen contents, shear force, fatty acid and amino acid contents of pork rinds were investigated. White pork rinds (WPR) and black pork rinds (BPR) were evaluated before and after heating to compare the differences between breeds and the effects of heating treatment. In the chemical composition test, the respective moisture contents for WPR and BPR before heating were 49.90% and 53.75% but increased to 60.75% and 61.09% after heating. The test for crude protein and crude fat contents showed lower values after heating but WPR was higher than BPR. In the color test, the L value decreased rapidly with heating, dropping from 68.75 to 45.11 in WPR and from 67.22 to 49.64 in BPR. WPR had a higher L value and a lower a value than BPR before heating but had a higher L value and a lower a value than WPR after heating. pH was significantly higher in WPR than BPR regardless of heating (p<0.05). The collagen content for WPR and BPR was 10.38 g/100 g and 11.54 g/100 g but increased to 12.00 g/100 g in WPR and decreased to 11.40 g/100 g in BPR after heating. The shear force of 26.14 kgf in WPR was significantly higher than 12.89 kgf in BPR before heating (p<0.05), but the values decreased significantly after heating in both WPR and BPR. Linoleic acid in WPR was 17.29%, which was higher than 15.13% in BPR. The USFA for BPR was also higher than WPR. In amino acid composition, the EAA contents in WPR was 7,190 mg%, which was higher than 5,520 mg% in BPR.

This study suggests a model for continuing and comprehensive management of hypertension or Type 2 diabetes mellitus (T2DM) in Korea. Moreover, this paper computed the contribution cost of hypertension or T2DM management using the healthcare medical cost, which could have occurred from stroke, myocardial infarction (MI), and end-stage renal disease (ESRD) that were successfully prevented from the effective hypertension or T2DM management. Additionally, these costs were compared with the cost of implementing the hypertension or T2DM management model suggested in this study. This study used the medical fee summary of the health insurance claims submitted to National Health Insurance Corporation by medical facilities for services provided during the period from January 1st 1999 to December 31st 2006. The prevalence rate with treatment referred to cases in which patients submitted their medical claims at least once during the period, along with an accordant diagnosis. The incidence rate with treatment referred to cases in which patients who never submitted claims for the accordant disease during the five years from 1999 to 2003 submitted claims for the accordant disease in 2004 and 2005. The relative risk of the occurrence of stroke, MI and ESRD was 11.0, 13.6, and 30.3, respectively. The attributable risk of hypertension or T2DM for stroke was 0.730, and that for MI and ESRD were 0.773 and 0.888, respectively. Based on these, the contribution cost of hypertension or T2DM is estimated to be 986.3 billion Korean Won(KRW) for stroke patients, 330.5 billion KRW for MI patients, and 561.7 billion KRW for ESRD patients as in 2005. Hence, the total contribution cost of hypertension or T2DM to stroke, MI, and ESRD is 1.878 trillion KRW. The estimate for operational costs included an annual expenditure of 50,000 KRW per each recipient and an annual subsidy of 0.22 million KRW per person for he 1.6 million low-income individuals with hypertension or T2DM to cover their out-of-pocket medical expenses. Under this assumption, it took approximately 0.6 trillion KRW to manage 5 million high-risk patients in the low- and mid-income range, coverings up to 50% of costs. In conclusion, considering the potential benefits of preventing stroke, MI, and ESRD, the costs seems to be reasonable.

The level of copayment increased in order to stabilize the financial condition of the health insurance on 1986. An important question regarding the policy was whether the increase in the level of copayments reduced the utilization of medical services in the poor selectively. In spite of the importance of the research question, no study has been reported. This study was designed to find out changes in numbers of physician visits, to explain characteristics influencing the difference of utilization before and after the program. Finally the interaction effect between the program and the level of income was examined for the abover question. A total of 10,421 persons from eight institutions was selected as the study sample. Research findings are as follows. 1. The number of physician visits decreased by ten percent as a result of increasing the level of copayment. 2. The decrease was remarkable in some groups such as children, rural area and large family. 3. The most important factor which explained the difference was the number of physician visits before the introduction of the new program. The more numbers of physian visits during the last year were, the more numbers of physian visits decreased after the program. 4. The interaction term between the program and the level of income was statistically significant in the multiple regression model which explained physician visits and its coefficient was negative. It means that an increase in copayment did not reduced the number of physician visits in the poor, selectively. 5. It can be concluded that imposing adequate copayment reduces the use of medical services as well as medical costs without serious damage in access especially for the poor people.
