In order to determine the physiolosical characteristics of plum fruits(Oishi wase) during maturation and guilty according to temperature after harvest, (2-chloroethyl) phosphonic acid(ethphon) 390ppm was sprayed on plum tree 11days before commercial matuarity in Suwon area. And also this study was acted to investigate fruits quility(Formosa) influenced by temperature(room, low) and polyethylene films(0.03, 0.06, 0.1mm), 1. Effect of ethphon on the fruits maturation and fruits(Oishi wase) quility according to temperature ofter harvest. Ethephon stimulated fruits ripening but the firmness was reduced rapidly. Soluble solids and titratable acidity was not very different than each treatment. Carbon dioxide and ethylene production were advanced and the production peak were shown earlier by ethephon treatment as compared with control fruit. Anthocyanin development was enhansed rapidly by ethephon treatment but it exerted a bad influence on fruits color after harvest, The soluble sugars in fluits were mainly glucose, sucrose, and fructose. Those content were higher in treated fruit than control. The organic acid was mainly malic acid. The shelf life was less than about 5days at room temperature and about 10 days at low temperature. 2. Fruits(Formosa) quility as affected by polyethylene film bagging. The polyethylene films well maintained the firmness both room and low temperature. Low temperature was more effective in maintaining titratable acidity than room temperature, especially polyethylene films. On the Other hand, soluble solids content was not shown wide differance between room and low temperature. Polyethylene film showed a high resperation rate, the rate was higher at room temperature than low temperature and thicker films revealed higher rate. Otherwise, ethylene production was low in all treatment Polyethylene film inhibited the coloration of fruits, decreased anthocyanin content. Fruits coloration delayed by low temperature in control. The shelf life of plum fruits was about 6 days at room temperature and 13 days at low temperature in control Polyethylene film had no advantage on shelf life both at room and low temperature.

In recent years there has been a rapid influx of high cost MRI equipment into Korea. This diffusion has raised concerns about the changes it will bring for the health care utilization. Therefore, the purpose of this study is to identify socio-economic characteristics of MRI uses in Korea. A structured questionnaire was designed for this purpose, and 1, 091 users were surveyed at the 35 MRI units of 33 hospitals during a week, sometimes March 1992. The study reveals that high cost technology such as MRI, CT scanner is so prevalent in Korea. This is particularly the case in metropolitan areas. Among others, Seoul has the highest percentage of MRI equipment, 51.05%, Pusan 12.10% and Kwangju 11.9%. Unfortunately, most high cost technology equipments are foreign products. Thus, hospitals with such a high cost technology have difficulties in maintenance of the equipment. The average performance of MRI equipment has declined from 10.2 cases per day in 1988 to 7.16 cases in March 1992. Due to the rapid increase, the performance of MRI equipment seems to be deterioration. Male usere are dominant in the case of MRI use. The utilization rate has positively increased with the rise of educational level of users. The same is true for the level of income; the MRI utilization rate by income level shows that it is negatively proportional to income, which indicates that the poor have difficulties in the use of high cost technology. Particularly, the cost of MRI is so high that ordinary patients are unable to pay for it. For example, 86.3% of respondents have answered that the cost is too high even though they are insured by health insurance. This is the first empirical study on the use status of MRI. The information obtained in this study is sufficient to maintain that the Korean health insurance programme is urgently in need of improving the insurance benefit schemes. The easiest way to do this is to include provision of high cost technology service into the benefit package.

고분자전해질 연료전지(PEMFC)의 성능이 개선됨에 따라 생성물인 물과 열의 발생이 증가하고 이를 처리하기 위한 관리기법이 중요해지고 있다. 본 연구에서는 물 관리 기법으로 수소 재순환을 적용하였고, 수소 재순환 유량(flow rate)과 퍼지 간격(purge interval) 및 지속 시간(duration)이 연료전지의 성능에 미치는 영향에 대한 실험을 수행하였다. Purge 조건의 영향을 해석하기 위하여 수소극의 압력, 연료의 습도, 운전 간의 연료 이용 효율과 물 배출 양을 측정하였다. 수소 재순환 유량이 증가할수록 수소극 출구의 압력 저하로 인하여 스택 성능이 낮아졌다. Purge 조건에 따라서 물을 효과적으로 배출하지 못해 순간적인 전압 강하가 발생하거나 혹은 잦은 purge로 인해 수소극의 습도를 유지하지 못하여 성능이 점차적으로 감소하는 것을 확인하였다. Purge 조건 실험을 통하여 수소극의 습도를 유지하고 응축된 물을 충분히 배출할 수 있는 purge interval과 duration을 선정하였고, 이를 통하여 스택의 성능과 연료 이용 효율을 향상시킬 수 있었다.

In the study, we suggest that the activation plan of the public nature burial in the capital area through funeral information system as follows. First, according to the report on the social survey announced by the National Statistical Office in December 2017, the Korean people's preference of nature burial was 43.6% while the actual utilization rate of national nature burial in 2017 was only 8.8%, which showed a huge gap between preference and utilization rate of nature burial. Therefore, through the activities to improve the awareness of nature burial by performing the national promotion and education, and also the investment for the expansion or improvement of nature burial facilities in the level of central government and local government, the preference of nature burial should be led to the actual demand. Second, during the period from 2011 to 2018, the utilization rate of public nature burial in the capital area was annually increased by average 26.9%, which showed the huge increase of demand for nature burial. Thus, each local government should carry forward the policies for expanding the supply of public nature burial focusing on the woodland burial showing the high preference of users of public nature burial. Third, even though the public cremation facilities are installed or operated by local governments in the capital area, Seongnam City without the public cremation facilities should install the public nature burial for the enhancement of users convenience by providing the One Stop Total Funeral Service.

Purpose: This study assessed the status of the Development and Utilization of critical pathways (CP) in South Korea. Methods: We surveyed 195 hospitals obtained on the Korean Hospital Association website. Data were collected using structured questionnaires for staff members in charge of CP management personnel in these hospitals. The questionnaire included CP developed by the institutions, the coverage rates and completion rates of CP in the current year, and management indicators related to CP. The questionnaire also included CP support systems and content within the institutions and questions regarding the advantages of CP utilization and obstacles associated with the CP development process. Results: Analysis of the responses from 70 hospitals (35.9% response rate) showed that a total of 1,370 CP sets were developed. The number of CP related to surgery departments was 365 (26.6%), and CP related to surgery and procedure was 1,093 (79.8%), respectively. The CP coverage rate was the most frequently used indicator to monitor the effect of CP (97.1%), followed by the completion rate (90.0%) and the length of stay in hospital (61.4%). CP managers reported that CP were highly useful for communication (3.39±0.493) and accurate information provision (3.39±0.491). The perception that CP violated doctors' autonomy in treatment was relatively low (2.87±0.645). Conclusion: It is necessary to establish an infrastructure in hospitals for CP. CP can facilitate communication and provide accurate information.
