The membrane of the LNG carriers consists of thin strips of INVAR(Fe-36%Ni) steel plates, and the junction between INVAR strips is fabricated by welding. Thousands of the raised edge joints, regularly spaced, are located around all the side of the tank corner near the transverse bulkhead, and TIG welding is manually made on the top of the raised edges. Since the thickness of all the laminated edge plies is extremely thin and the weld position is under a bad accessibility, highly skilled workers are required to perform welding relatively for a long welding time. An alternative scheme for the corner membrane fabrication is proposed in the study to improve the installation workability and thus productivity. The scheme replaces the welded edges with the preformed corrugation ones. A panel strip with regularly-spaced corrugations is installed at the corner instead of the individual flat strip of which edge is vertically raised to be welded with the adjacent strip. In the study, a series of the evaluation on the corrugated edge members was performed to assess the applicability to the real LNG carrier fabrication. Opening displacement at the raised edge was experimentally examined. Elastic stiffness regressed from the displacement was nearly same in both edge types. Edge displacement and local stresses were calculated under hydrostatic pressure and temperature change due to liquefied cargo. Fatigue test was performed on both corrugated and welded edge specimens consisting of two or five plies of invar strips. Fatigue strength of the corrugated specimens was not less than that of the welded specimens.

Purpose: The purpose of this study was to investigate the wage structure of hospital nurses in Korea and to analyze the factors that determine the level of nurses' wages. Methods: First, a mobile survey on nurses' wages was conducted with a total of 3,742 nurses working in hospitals. A literature review was also done. Second, a regression model was applied to analyze the determinants of nurses' wages. Results: The average monthly wage of 3,742 nurses based on the survey was KRW 3,588,000 and the standardized monthly income of 3,742 nurses was estimated to be KRW 3,364,000 as of the end of 2018. The results of regression analysis(R²=61.7%) showed that gender, nursing experience, designated night duty, ownership, and number of beds were statistically significant variables for nurses' wages at 1% significance level. The monthly wage of nurses working in total nursing care wards was not significantly different from those working in other wards at 5% significance level. Conclusion: The substantial difference in nurses' wages according to job career, hospital size, region, etc may result in the low proportion of nurses with more than three to five years of service experience and the high turnover of less-experienced workers. Consideration should be given to adjust the gap in wage level and a standard nurse wage system could be effective measures.

Methods: This study was performed to estimate the use of frozen convenience food in middle schools located in the Daegu district. Objectives: These schools have directly managed school meal services. The subjects for this study were 145 students and 66 dieticians. The study involved a survey on food preference and quantity satisfaction of the students and the frequency of use of frozen convenience food in the daily menu. Results: As the result, 50.0% of the students were not satisfied with the meat and poultry quantity from school meals(felt small), and 25.0% of students were not satisfied with vegetables(felt much). The majority of students (50.7%) who were not satisfied with vegetables said they were dissatisfied with the school food because of the taste. On the other hand, 36.6% said they were dissatisfied because they dislike vegetables in general. As for the use and frequency rate of frozen convenience food, the survey results were revealed in the order of dumpling 58.3% > processed meat 50.0% > chicken 50.0% > frozen marine food 40.4% > cuttlefish 30.3% > miscellaneous 26.3% > vegetable & potatoes 14.4%. It was found that many schools employing more than five workers did not use flour-based frozen foods in their menu. As for the use of the frozen processed food, many schools which had an average food cost of more than 1,700 Won were found to use frozen foods more than once a month. In addition, chicken was not used often at the schools whose average food cost was less than 1,500 Won while many schools, whose average food items cost was more than 1,500 Won, incorporated chicken into the menu once a month. Processed flour food [hot dog] was used often by schools whose average food cost was between 1,500 Won and 1,600 Won. As for the actual conditions of using frozen convenience food, there was a significant difference in the use of chicken in relation with the number of food service recipients. As a result, the use of frozen convenience food has been shown to be related with food cost, number of food preparers, and the number of school students.

농촌 여성들의 출산력과 임신소모율을 조사하기 위해 군위군에 거주하는 15-49세의 여성 가운데 조사시작 당시 영구불임 수술을 하지 않은 유배우 가임여성을 대상으로 17명의 면 보건요원들이 1985년 4원 1일부터 1987년 3월 31일까지 2년간 추적 관찰하여 그들의 피임 실천율, 출산율 그리고 임신 소모율을 조사하였다. 총 관찰된 6,826 여성인년 가운데 피임을 실천한 기간은 3,522인년(51.6%), 임신, 유산 그리고 출산을 한 기간은 519인년(7.6%)이었으며 피임을 하지 않은 기간은 2,491인년(36.5%)이었다. 조사시작 당시에 영구불임 수술을 한 사람을 포함시켰을 경우에는 피임을 실천한 기간이 72.1%로 전국의 피임 실천율보다 오히려 높은 수준이었다. 그러나 30대 여성의 경우 2-3명의 자녀를 갖고서도 피임을 하지 않고 있는 사람이 약 28%나 되고, 피임을 하는 경우에도 월경 주기법이나 콘돔과 같은 실패율이 높은 피임법을 20대 여성보다 더 많이 쓰고 있었다. 관찰기간 동안 전체적으로는 100 여성인년당 14.3건의 임신이 일어났으며, 25-29세 여성 이 100 여성인년당 27.4건의 임신으로 가장 높은 임신율을 보였다. 전체임신 중 22.0%가 사산(0.9%), 자연유산(3.8%), 그리고 인공유산(17.3%)으로 소모되었다. 연령이 증가함에 따라 임신 소모율이 증가하여 30세 미만 부인의 임신 소모율은 15.8%인데 비해 30대 여성이 임신을 한 경우 37.5%가 인공유산을 하여 자연유산과 사산을 합한 임신 소모율이 43.5%나 되었다. 추적기간 동안에 인공유산으로 종결한 부인이 출생으로 종결한 부인에 비해 평균 자녀수와 자연유산 및 인공유산 경험회수가2배 이상으로 많아 유산을 경험한 사람이 유산을 반복하고 있었다. 출생으로 종결한 임부는 평균 4.2회의 산전 관리를 받았고 분만은 85%가 의료기관에서 일어났으며, 가정 분만은 15%로 전국의 농촌지역에 비해 높은 시설 분만율을 나타냈는데, 이것은 군위군이 일차 보건의료시범사업 지역이었기 때문으로 생각된다. 이와 같은 연구 결과로 보아 농촌 여성을 대상으로 한 가족계획 사업은 30대 여성을 대상으로 하여 경구 피임약이나 자궁내장치와 같이 피임 효과가 높은 피임법을 보급하는데 중점을 두어야 임신 소모율을 줄이고 여성건강을 증진시킬 수 있을 것으로 생각된다.

To improve the quality of environmental measurements and evaluation of the workplace air in the pigment manufacturing industries, we analyzed metal(chromium, cadmium, lead, iron, cobalt, manganese, antimony, titanium, arsenic, and selenium) concentrations by ICP-AES in sixty seven samples of inorganic bulk pigments which are produced and/or used in Korea. We also collected MSDS which has to be supplied by manufacturer and/or supplier and posted in the workplace according to the Hazard Communication Standards, and compared the number of metals listed in each MSDS with the number of metals determined by ICP-AES. Results were as followed; 1. Among seventeen yellowish-colored samples, chromium(2~19%) and lead(0.1~61%) were the two major metals. In thirteen reddish-colored samples, iron was the major component with 37~81%. Cobalt and manganese were detected in blue-colored samples with less than 1%, while antimony and titanium were the major two metals in white-colored pigments with 178~300 ppm and with 36~65%, respectively. 2. In area samples collected in workplace air(one pigments producing factory and five retailer stores), iron and manganese were detected but the concentrations not exceeded the TLVs(1 and $5mg/m^3$, respectively). In three of fifteen samples, the concentrations of lead exceeded the TLV ($0.05mg/m^3$). 3. Two out of seven companies provided MSDS, and the average provision rate was 22.4%. And the coincidence rate of the number of metals referenced in MSDS and determined by ICP-AES mostly accorded, but in one sample, different metal was detected from MSDS. In summary, metals have to be concerned in evaluation of the workplace air dealing with compounds of inorganic pigments dust are cobalt, chromium, iron, manganese, lead and antimony, and these are simultaneously determined by ICP-AES. Taking this opportunity, it is needed to reinforce that the personnel is to be concerned about prevention of workers' ill health regarding to provision of MSDS.

Reorganization of myun health care service is one of the main issues in health care delivery in rural Korea. The fundamenta, concept of the role and function of the myun health subcenter is that it is the basic unit of rural health care service and is to provide comprehensive health care service through the integration of curative and preventive services. The aim of this study is to analyze the patterns of curative activities in the myun health subcenter in terms of the most prevalent types of diseases, necessary diagnostic methods and required equipment, types of treatment, necessary drugs and materials, and finally the cost of curative services. The population on which this study was done was the 1596 patients who visited the two myun health subcenters (Sunwon Myun and Naega Myun) in Kang Wha County, the area of the Yonsei University Community Health Teaching Project, during period from May 1, 1975 to June 10, 1976. For the patient's record in the clinic, problem oriented medical records were used. Decisions regarding the disease classification, the diagnostic methods used and selection of the most appropriate and adequate medical treatment were made by a group of three experienced physicians after reviewing the medical records which had been written by public physicians who were treating patients in the study area. The records were reviewed by resident staff members of the Department of Preventive Medicine, of Yonsei University College of Medicine. A brief summary of results of the study is as follow: 1. 29.9% of the patients who visited the clinics were ages between 0-4. No sex difference was observed among patients less than 20 years of age. However, among patients over 20 years old, females predominated. Thus it is evident that the majority of patients were either children or mothers and grandmothers. 2. The distance from the individual villages to the myun health subcenter was one of important factors in determining the ratio of clinic visits. However, other factors such as the activities of the health workers also affected the rates substantially. 3. The most common 25 diseases comprised 90.2% of all the diseases recorded. Acute respiratory infection (25.5%), Skin (12.7%) , diarrheal diseases (6.8%), neuralgia and back pain (4.9%) and. all other injuries (3.9%) were the five most common diseases. 4. Of all the diseases diagnosed and treated, 9.2% required simple laboratory tests for diagnosis, 6.5% required X-ray examination, and altogether 13.6% required either laboratory test or X-ray examination. 5. Treatment and management of 42.0% of the cases could be accomplished with simple, inexpensive drugs, 12.8% required the use of more expensive drugs (mostly antibiotics) and injections were required in 19.7% of the cases. Minor surgery and referral were necessary in 5% of the cases. 6. The cost for diagnosis and treatment was estimated with a standard which was set by general concensus. The average cost of diagnosis was 144 per case and the cost of treatment was 726 per case, The Total average cost per visit was 870.
