Priority setting in national health insurances in major advanced countries and the nation was investigated to draw the criteria for priority setting and suggest the most rational criteria for dental insurance so as to help secure the efficiency of medicare financing and individual's health right and also elevate medical consumers' satisfaction with health insurance. 1. Priorities in national health insurance are different from country to country, depending on the medical security systems, priority introducing conditions, and social environment, but have many common factors. 2. The priority setting criteria for national health insurance in those countries include the following in common: the efficiency, equity, and cost effect of treatment, emergency of treatment, consumption of expense, efficacy of treatment, patient's receptiveness, patient's demand, severity of disease, and patient's responsibility for the disease. 3. In oral diseases, severe diseases including oral cavity cancer are low in rate, and in-hospital treatments are few. From the above findings, it is suggested that dental insurance should establish discriminative criteria for priority setting by reflecting the aspects of dental diseases and system difference between dental and other health insurances and taking account of efficiency of treatment through prevention, cost effect, prevalence and incidence of generalized diseases, and individual's financing burden.

목 적 : 최적화 알고리즘에 적용되는 최적화 인자들의 영향을 고려하여, 가장 적합한 인자 값을 도출함으로써 이상적인 치료계획을 쉽게 설계할 수 있도록 하고자 한다. 대상 및 방법 : 본 연구의 세기조절방사선치료에서 선량계산 알고리즘은 PBC(Pencil Beam Convolution)이고, 최적화 알고리즘은 DVO(Dose Volume Optimizer 10.0.28)이다. 두경부 환자의 세기조절방사선치료에서 치료계획용적의 처방선량은 동시에 2.2 Gy와 2.0 Gy가 될 수 있도록 하였다. 치료계획은 6 MV, 7개의 조사야로 역선량계산방법으로 수립하였다. 최적화 알고리즘 인자는 용적선량-조건강도(Priority, Constrain), 선량부 드럼강도(Smooth)로 선정하고, 각 인자들의 변화량에 따른 치료계획의 영향을 분석하였다. 용적선량-조건강도는 기준 조건강도를 정하고, 비율은 같지만 절대 값은 다른 최적화 과정을 실시하였다. 또한 조건강도의 절대 값에 변화에 따른 치료용적과 주변 정상장기들을 평가하였다. 선량부드럼강도는 기준 조건의 단순 변화와 용적선량-조건강도와 관련시킨 변화를 치료계획에 반영시켰다. 치료계획은 처방선량지수(Conformal Index, CI), 처방선량포함지수(Paddick's Conformal Index, PCI), 선량균질지수(Homogeneity Index, HI)와 각 장기의 평균선량으로 평가하였다. 결 과 : 용적선량-조건강도의 비율을 동일하게 하고 절대 값을 변화 시켰을 때 CI값은 다르지만, PCI는 $1.299{\pm}0.006$, HI는 $1.095{\pm}0.004$, D5%/D95%는 $1.090{\pm}1.011$으로 처방선량에 대한 영향은 유사하였다. 이하선의 평균선량은 용적선량-조건강도의 절대 값이 40, 60, 70, 90으로 증가될 때, 67.4, 50.3, 51.2, 47.1 Gy로 감소하였다. 각각의 치료계획에서 선량부드럼강도를 증가시켰을 때, PCI는 $1.338{\pm}0.006$로 증가된 값을 보였다. 결 론 : 용적선량-조건강도는 절대적인 값보다 각 조건의 비율에 따라 최적화 알고리즘에 영향을 주었다. 절대 값이 다르더라도 같은 비율을 유지하면 유사한 치료계획이 수립되었다. 성공적인 치료계획을 수립하기 위해 특히 보호해야할 정상장기의 용적선량-조건강도는 치료용적의 용적선량-조건강도의 50%이상 되어야한다. 선량부드럼강도는 용적선량-조건강도에 따라 비례하여 증가하거나 감소하여야 한다. 단순히 절대 값으로 적용하면 용적선량-조건강도는 그 조건을 충분히 만족시키지 못한다.

The purpose of the study is to optimally manage sewage treatment plant with analysis of phosphorus contribution and improvement of water quality contributing rate in the effect of inflowing point of effluent and Pal-Dang lake after reducing T-P discharge from large scale public sewage treatment plant at upstream of Pal-Dang lake. Also, this study, for enforcement of T-P in effluent, plans optimal management of effluent T-P through examining propriety of environmental, technological, and economical aspect such as water quality standard of domestic and foreign T-P and related policy. In regarding optimal management of T-P discharged from public sewage treatment plant located in upstream of Pal-Dang lake, the study drew following conclusions. With the optimal management of public sewage treatment plant, it showed that a pollution level became higher in the order of Sumgang E in South-Han river, C in Dalcheon, B1 B2, A in North-Han river, and J in Kyungancheon, and it is required reduction of T-P first. The highest value in analysis of benefit-costs from sewage treatment plant in the selected research area was Kyungan B, and the others are with the order of Jojong A, Bokha A, Kyungan A, and Yanghwa A. With result of this study, all 14 areas are required more enforced phosphorus treatment. The study resulted that the most top priority areas were Hangang F, Sumgang B, and Gyungan A, top priority areas were Bokha A, Dalcheon B, and Cheongmi A, priority areas were Hangang E, Heukcheon A, Gyungan B, and Jojong A, and potential areas were Sumgang A, Yanghwa A, Dalcheon A, and Hangang D. It seems to be appropriate to apply 0.2 mg/L of T-P treatment for water supply source reservation, 0.5 mg/L for the other areas by locally, and 0.2~0.5 mg/L for biological nitrogen phosphorus treatment method and 0.5~1 mg/L for Conventional Activated Sludge by technologically. Also, it may be appropriate to apply 0.2 mg/L for the most top priority area(I), 0.3 mg/L for the top priority area(II), 0.4 mg/L for priority area(III), and 0.5 mg/L for potential area(IV) by the separation of priority area.

We tried to evaluate frequencies and severities of malocclusion of various socioeconomic areas according to growth and development. To obtain objective validity, we used Handicapping Labiolingual Deviation (HLD) suggested by Draker, Treatment Priority Index (TPI) by Grainger, Handicapped Malocclusion Assessing Record (HMAR) by American Dental Association and American Association of Orthodontist. Seoul and Kwangju were selected as an urban group, Ahnyang as an middle socioeconomic group and Hwasun near the Kwangju area as an rural group. 140 (male 63, female 73) of 5th grade in 'E' elementary school students in Seoul, 202 (male 101, female 101) of 'S' elementary school students in Kwangju, 207(male 105, female 102) of 'H' elementary school students in Hwasun, and 100(male 49, female 51) of 'M' elementary school students of in Ahnyang of all the same grade were analyzed and we obtained the results as follows; 1. TPI, HLD, and HMAR showed high coincidence and reproducibility between different observer. (p<0.01) 2. In comparison of TPI, HLD, and HMAR according to clinical decision, there was statistically difference between each other. (p<0.01) 3. As the severity of malocclusion increases there was high correlation between TPI and HLD, and between HLD and HMAR (p<0.05) 4. With respect to differences between areas in TPI and HLD, there was statistically difference between Ahnyang and other areas. 5. In Seoul as an urban group there was a high incidence of periodic checkup and history of orthodontic treatment than other area. 6. Mode of feeding and posture during sleeping did not affect the severity of malocclusion. As a conclusion, TPI, HLD and HMAR are so reproducible and coincident that they can be used as a guide on evaluating the frequency and severity of malocclusion and determining the priority of orthodontic treatment to determine the need and supply of orthodontic treatment. Furthermore these indices can provide objectively valid data for establishing public health problem solution.

The objective of this study is to analyze the investment adequacy of the projects implemented according to the master plan on sewerage rehabilitation at Seoul. The planned and actually implemented ratio of invested money on sewage treatment plants (STPs) to sewers were compared in two temporal periods. Though the planned ratio of investment on STPs to sewers was 50:50 (in 2009-2020), the actual implemented ratio in 2009-2013 was 34:66. Until 2020, the greater investment ratio on STPs to sewers should be made considering the necessity of coping with stricter legal compliance on advanced treatment, stormwater treatment and so on. The priority of the planned and partially implemented projects among four STPs and at each STP was evaluated. Considering only the performance indicator of reduced load of BOD, T-N, T-P per the capacity of each STP facility, the performance among four STPs was shown as Jung-Rang>Tan-Cheon>Seo-Nam>Nan-Ji. The reverse order of the performance results in the past may be considered for future investment priority, but the efficiency of operation implemented at each STP, deteriorated status of each STP, investment in the past and so forth should also be considered. As for the priority of projects conducted within each STP, projects related to legal compliance (such as advanced tertiary treatment, stormwater treatment, etc.) have highest priority. Odor-related project and inhabitant-friendly facility related projects (such as building park on STPs, etc.) has lower priority than water quality related projects but interactivity with end-users of sewerage should also be important.

Purpose : This study explores unmet medical services within a region for patients admitted to a single medical institution in one region and was to analyze the importance and satisfaction of hospital selection attributes. Through this, we tried to solve the unmet medical needs of patients and provide useful basic data in terms of hospital management in the region. Methods : It were collected to a total of 250 questionnaires for patients admitted to the regional integrative medical hospital. However, 232 samples were used for the final analysis, excluding 18 copies not reported in good faith. For the analysis, first, demographic frequency analysis of inpatients and inpatients was performed, and second, characteristics of patients, including frequent disease receiving treatment, were analyzed. Next, descriptive statistics analysis was conducted on unmet medical service intentions. In terms of hospital selection attribute, the items of continuity maintenance (I quadrant), priority visibility (II quadrant), low priority (III quadrant), and excessive effort (IV quadrant) were derived using the IPA (importance-performance analysis) matrix technique. Results : The derived results were classified by item and area. In the priority administration area, it was the reputation and recognition of medical institutions and the service area of medical institutions. In the case of items, there were 6 items including the importance of surgery and medical expenses, and diet at hospitalization. 1) Conclusion : Thus a result of this study, resources are efficiently allocated to priority correction areas with high importance but low satisfaction and circulatory medical treatment is performed in the departments required by patients who use medical care and, various methods, such as preparing a policy to support medical expenses, should be sought.

This study was carried out to show how the Analytic Hierarchy Process technique could be used in setting the priority among selected diseases to increase the range of health insurance benefit. Thirty experts, including doctors (group1), experts for preventive medicine or public health(group2), and representatives of the insured(group 3), participated in the study panel that is conducted for priority setting. They were asked to evaluate the priorities among 6 selected criteria and then 42 selected diseases. The results were as follows; First, representatives of the insured think that the magnitude of out-of-pocket payment should have high priority while doctors think that effectiveness of treatment should have high priority. Second, all experts think that catastrophic diseases such as malignant neoplasm, major heart disease, and cerebral vascular disease should have high priority in health insurance coverage even though there is little difference among groups. These results can be useful to establish a systematic strategy for expanding health insurance benefit package.

This study was to find a patient's motive for receiving implant treatment by age and gender using a self-reporting questionnaire survey with adults(men & women) in Woolsan. The result was as follows: 1. As a result of questionnaire survey with 155 patients in total(86 men, 69 women), 24 of 86 men(27.9%) valued the natural mastication feature of dental implant most, that is as similar as natural teeth, while 18 of 69 women(26.1%) had the most priority over the longer life of implant than common dental prostheses. By age, those in their 20s and 30s had a preference to implant treatment because it does not need to pulling out teeth for prostheses, while those in their 40s and over had a priority to the natural mastication feature of implant that is similar as much as natural teeth. By dental treatment, all of respondents said that the natural mastication feature is the most important in getting dental implant. It was founded that whether one can taste food as it is or not is less important, regardless of age or gender. 2. The greatest obstacle to implant surgery was expensive medical fees, 88 of 155 respondents(56.8%), with a fear of surgery itself being the least obstacle. 3. 90.2% of the total respondents said that they will want to receive dental implant treatment if their economy allow.

Dead oscars (Astronotus ocellatus) were presented for necropsy in January, 2005. Oscars, which had been reared densely, were dead in large quantities. At necropsy, they were severely infected by Dactylogyrus spp. We requested for the oscar samples which had been raised in the same water tank. Two of them were sacrificed and necropsied. At the microscopic examination, we verified dactylogyrosis of oscars. The other oscars were treated by praziquantel. Treatment was started with a dosage of 2.5 mg/L. From a second day, we treated 5.0 mg/L every two days during 4 days. At sixth day, No Dactylogyrus flukes were found but only larvae were existed. After 2 weeks without additional medication, both Dactylogyrus flukes and larvae were eliminated.
