본 연구는 만 11세에서 18세 사이에 해당하는 소년원 여학생과 대학병원 소아치과에 내원한 동일한 연령대 환자들의 구강 건강상태를 조사하여 차이점을 비교하고자 시행되었다. 최근 5년간 누적된 소년원 여학생과 아주대학교병원 소아치과에 내원한 환자의 치과기록을 수집하여 치과치료에 분석하였다. 소년원 여학생과 대학병원 환자 모두 수복치료가 가장 높은 비중을 차지하였다. 소년원 여학생에서는 치아우식에 의한 영구치의 발거가 중,고등학교 시기에 점차 증가한 반면에 대학병원 환자에서는 영구치의 발거 비율이 적었다. 현재 수용되어있는 만 11부터 18세까지의 소년원 여학생 130명과 최근 1년간 대학 병원 소아치과에 내원한 환자에 대해 구강검진을 시행하여 우식, 상실, 충전 치아 수를 검사하여 구강건강상태를 조사하였다. 우식경험영구치지수가 대학병원에서 4.15인 반면에 소년원 여학생에서는 7.53로 약 2배 높았다.

Unlike other educational spaces in school facilities, restrooms have remained unpleasant spaces without reflecting the change in social awareness and students' lifestyle. In the process of the 'School Restroom Environment Remodeling Project in Seoul' by means of "user participatory design method", this study aimed to suggest a design of the school restroom environment responding to the different needs of actual users, who are students and school staffs. By surveying them, it was revealed that they have a variety of respective behavioral patterns and spatial needs according to their status, gender, age and working period. Implications of this study are as follows; First, it is necessary to establish a separate restroom facility standards that respond to the characteristics of elementary school students. Second, there should be an expansive approach to widely accommodate with the users' needs that were found out through 'user participation', more than just repairing pre-existing space. Third, it needs to have critical review of the maintenance and operation system itself as well as the improvement of the school restroom environment.

We consider facility layout problems, where mn facility units are assigned into mn cells. These cells are arranged into a rectangular pattern with m rows and n columns. In order to solve this cell type facility layout problem, many approximation algorithms with improved local search methods were studied because it was quite difficult to find exact optimum of such problem in case of large size problem. In this paper, new algorithms based on Simulated Annealing (SA) method with two neighborhood generation methods are proposed. The new neighborhood generation method adopts the exchanging operation of facility units in accordance with adjacent preference. For evaluating the performance of the neighborhood generation method, three algorithms, previous SA algorithm with random 2-opt neighborhood generation method, the SA-based algorithm with the new neighborhood generation method (SA1) and the SA-based algorithm with probabilistic selection of random 2-opt and the new neighborhood generation method (SA2), are developed and compared by experiment of solving same example problem. In case of numeric examples with problem type 1 (the optimum layout is given), SA1 algorithm could find excellent layout than other algorithms. However, in case of problem type 2 (random-prepared and optimum-unknown problem), SA2 was excellent more than other algorithms.

The purpose of this research is to analyzing the welfare function of the senior citizen with similar type of compounding the school facility, to analyze the problematical point of present condition. And also propose the spatial constitution which the student and the regional senior citizen are easy to utilize on the basis of the result. In a type of educational facility composition, it became clear that a ratio and the inflection order that elderly welfare facilities occupied of vacant class room were low. In other words, in composition of a school facilities, elderly welfare facilities can be said to be an important problem. As a result of having analyzed an existing compound facilities, there was limited interchange of student and a the aged. In addition, there were problems such as learning environment by an intersection of circulation. Therefore, composition of educational facility and elderly welfare facilities is not space composition that is intersection of simple specification function. In other words, a program of the common space which is necessary for the local community formation is necessary. Setting of semi-public area proposes the function of the existing facility and actual condition of spatial use in prerequisite.

In order to estimate the pattern of medical care utilization and recognition for health factor among the inhabitants in Wan-do district which is located off the southern seashore from mainland Korea, household interview survey was performed from January 15 to 30, 1990 in Wan-do Gun area. The results observed were following: 1. Among the users of medical facilities 40.8% used public health facility as first contact facility. Lower the income level was and longer the residency duration was, the utilization rate of public health facilities was higher. By age groups and medical security status the utilization pattern was likely to disperse to local clinic and secondary contact medical resources. 2. Medical expense and access time were significantly different between primary contact and secondary contact medical resources. 3. Public health facility was recognized as the favoured institute having advantage of geographic and economic accessibility. 4. Statistically significant determinants in public health facility utilization among total medical service were the region, the medical expense, and the access time.

Efficient financial management is a critical factor in achieving school foodservice goals. The objective of this study was to suggest efficient financial management practices in secondary school foodservices. In pursuit of this objective, we first identified performance indexes for measuring the success of financial management. Second, we suggested financial management standards, financial data classification methods and a report system. Last, we analyzed operating ratios with the financial data of self-operated and contract-managed school food services. The data were collected through an open-ended questionnaire from 10 middle/high school foodservices in Seoul and Kyeonggi Provincial during on-sites visits and interviews with dieticians and managers. Student participation, sales goals, re-contract frequency and number and cost of disaster loss were identified as the performance indexes for financial management. Income statements were compiled by identifying and classifying financial data. Total revenues consisted of subsidies, meal sales, other revenue and interest. Expenditures consisted of purchased food, salaries and wages, utility costs, office supplies, kitchen supplies, purchased services, company overhead indirect costs, facility investment and maintenance, facility usage expenses, employee benefits and miscellaneous. Mean price of a meal was 2,326 won at self-operated foodservices when the subsidies were included as revenues and 2,360 won at contract-managed foodservices. When including the subsidies as revenues, the operating ratios of self-operated foodservice showed that the food cost percentage was 66.9％, labor cost 23.2％, operation cost 9.9％ and profit 0％. The correspond figures at contract-managed foodservices were 57.6％, 21.5％, 15.3％, and 5.5％, respectively. Food costs in self-operated foodservices was significantly higher than that for contract-managed foodservices, however, facility investment and maintenance and facility usage expenses at self-operated foodservices was significantly lower than those for contract-managed foodservices. Based on this study, the methodology and classification system of financial data was found to be applicable to assess the financial structure of school foodservices.

학교시설은 근린주거지역의 핵심시설로서 물리적, 사회적으로 중요한 위치를 차지한다. 이러한 학교시설용지가 활용되지 못하는 경우, 규모와 입지의 특성상 지역주민들의 환경을 저해하는 요인으로 작용하게 되며, 지역의 토지자원에 막대한 낭비를 초래한다. 따라서 학교시설용지의 미매각화 현상에 대한 원인을 규명하고, 이를 미연에 방지하기 위한 제도의 마련이 필요한 실정이다. 한편, 발생한 미매각 학교용지에 대해서는 용도의 전환 등을 통하여 빠른 활용이 가능하도록 유도 할 필요가 있다.
