Nowadays, the high development of industrial technique demands the optimal design of marine structures to be welded under the water, because the underwater welding of the ship hull and marine structures can decrease manpower and cost of production. However there is not available at present any report on fatigue behavior about underwater welded joints. In this paper under tention- tension repeated fatigue stress with frequency of 10 cycles per second by local controlled system, the fatigue strength properties of underwater welded joints of SM41A-2 Plate-to-Plate of 10 mm thickness were experimentally examined. The results obtained were as follows : 1) The fatigue strength of underwater welded joints of SM41A-2 was peaked at the heat input of about 1, 400 joule/mm(180 A, 36 V), while, at the heat input of more than about 1, 100 joule/mm (160 A, 33 V) that of the underwater welds at the higher than cycle of life rather than the lower cycle was higher than that of the base metal but lower than that of the atmosphere welds on account of both cooling and notch effects. 2) The fatigue limit of underwater welds increased with an increase of heat input resulting in a peak of that at the heat input of about 1, 400 joule/mm and then decreased gradually. 3) The fatigue strength at N cycles was peaked between the heat input of about 1, 400 and 1, 700 joule/mm where the strain was rapidly increased. 4) It was confirmed that the optimal zone of heat input condition for obtaining the underwater welds fatigue strength higher than that of the base metal exists, and if out of this zone, the fatigue strength of the underwater welds was lower than that of the base metal because of lack weld penetration, inclusion of slag, voids, etc. 5) By the fatigue test, the underwater welds fractured brittly without visual deformation, so the strain was remarkably less than of the atmosphere welds. 6) The fatigue life factor was peaked at the heat input of about 1, 600 joule/mm (200 A, 36 V) at which the mean strain is a little higher than that of the base metal but quite lower than those of the atmosphere welds, resulting in good underwater welds because both fatigue strength and ductility of the underwater welds are higher than those of the base metal at such heat input.

Changing concepts of health care, are stimulating the demand for health care, thereby orienting society to health care rights to such an extent that they are deemed as fundamental ones inalienable to man. Concomitantly, qualitative as well as quantative improvement is being sought in the nursing service field. Today, efforts are being made in various areas, especially to qualitatively improve nursing services. A second issue concerns proper staffing. It is important to study staffing, in as much as it continues to be the most persistent and critical problem facing hospital nursing administrators today. It involves quantity, quality, and utilization of nursing personnel. A great deal of attention has been focused on this problem since mid 1930's when nursing services began to be felt as an important segment of hospital operation representing the largest single item of hospital budgets. Traditionally, the determination and allocation of nursing personnel resources has relied heavily on gloval approaches which make use of fixed staff-to-patient ratios. It has long been recognized that these ratios are insensitive to variations between institutions and among individual patients. Therefore, the aim of this thesis is to point to the urgent need for the development of methodology and criteria suited to the reality of Korea. The present research selected one place, the W Christian Hospital, and was conducted over a period 10 days from January, and nurses who were them on duty in their unit. The total num-her of patients surveyed was 1,426 and that of 354. The research represents many variables affecting the direct patient care time using the result from the direct observation method, then using a calculation method to estimate the relationship between the patients care time and selected variables in the hospital setting. The amount of direct patient care time varies with many factors, such 89 the patients age. diagnosis and time in hospital. Differences are also found from hospital, clinic to clinic, ward to ward, and even shift to shift. In this research, the calculation method of estimating the required member of nursing staff is obtained by dividing the time of productive patient care activity(with the time of patient care observed), by the sum of the productive time that each the staff can supply, i.e., 360 minutes, which is obtained by deducting the time for personal activities. The results indicate a substantial difference between the time of productive patient care observed directing and the time of the productive patient care estimated using calculating method. If we know accurately the time of the direct patient care on a shift, there required number of staff members calculated if the proper method can be determinded should be able the time of the direct patient care be estimated by the patient classification system, but this research has shown this system to be in accurate in Korea. There are differences in the recommended time of productive patient care and the required number of nursing staff depending upon which method is used. The calculated result is not very accurate, so more research is needed on the patient classification system.

Small valves including ball valves, gate valves and butterfly valves have been adopted in the fields of steam power generation, petrochemical industry, carriers, and oil tankers. Butterfly valves have normally been applied to fields where in narrow places installing the existing valves such as gate valves and ball valves have proven difficult due to the surrounding area and the heavier of these valves. Butterfly valves are used to control the mass flow of the piping system under low pressure by rotating the circular disk installed inside. The butterfly valve is benefitted by having simpler structure in which the flow is controlled by rotating the disc circular plate along the center axis, whereas the weight of the valve is light compared to the gate valve and ball valve above-mentioned, as there is no additional bracket supporting the valve body. The manufacturing company needs to acquire the performance and life test equipment, in the case of adopting the improving factors to detect leakage and damage on the seat of the valve disc. However, small companies, which are manufacturing the industrial valves, normally sell their products without the life test, which is the reliability test and environment test, because of financial and manpower problems. Furthermore, the failure mode analysis of the products failed in the field is likewise problematic as there is no system collecting the failure data on sites for analyzing the failures of valves. The analyzing and researching process is not arranged systematically because of the financial problem. Therefore this study firstly tried to obtain information about the failure data from the sites, analyzed the failure mode based on the field data collected from the customers, and then obtained field data using measuring equipment. Secondly, we designed and manufactured the performance and life test equipment which also have the real time monitoring system with the naked eye for the butterfly valves. The concept of this equipment can also be adopted by other valves, such as the ball valve, gate valve, and various others. It can be applied to variously sized valves, ranging from 25 mm to large sized valves exceeding 3000 mm. Finally, this study carries out the life test with square wave pressure, using performance and life test equipment. The performance found out that the failures from the real time monitoring system were good. The results of this study can be expanded to the other valves like ball valves, gate valves, and control valves to find out the failure mode using the real time monitoring system for durability and performance tests.

This study researched into literature materials in order to utilize basic data on job importance in dental coordinator, and analyzed questionnaire on job importance in dental coordinator for about 2 months from August and September in 2008 targeting dental hygienists and other manpower for dental hospitals & clinics where are located in D region and neighboring region. The following are the results: 1. Dental hospital & clinics where dental coordinators work were surveyed to be totally 66.9%. Dental coordinators were indicated to be 71.1% as for dental hospital$^{\circ}{\S}$clinic(women), and to be 28.4% as for a case with none. There was significant difference according to final academic degree and working place(P<.001). 2. License holders(women) for dental hygienist as dental coordinator accounted for 39.8%. The opposite case accounted for 60.2%. A case of doing duty of dental coordinator given not dental hygienist was indicated to be high. There was significant difference according to working place(p<.01). 3. The task importance on job that a dental coordinator directly performs was indicated to be averagely 3.24, thereby having been recognized to be important. 4. As for the recognition on job importance according to working-year number, it was indicated to have higher recognition on task importance in the more working-year number regarding customer management(p<.01), organization management(p<.05), and self-management(p<.01). 5. Given seeing difference in recognition on task importance according to medical institution, it was indicated to be 3.34 for dental clinic and 3.25 for dental hospital. Thus, the task importance was indicated to be slightly high in a person who works for dental clinic. There was no significant difference. In light of the above results, in order to educate dental coordinator who can successfully perform a role at dental hospital & clinic, a dental hygienist is required who is equipped with dental-clinic career rather than a person without a major. A professionally educational program for dental coordinator needs to be developed. Even in a dental coordinator's task, there is necessity for the curricular development and the specialized education.

The purpose of this study was to analyze dental hygienists' opinions on health promotion projects in public health and their needs for specialized education in the projects, so that it could help prepare specialized education program required for health promotion projects in the future. To meet the goals, total 364 dental hygienists working in public health were asked to join a questionnaire survey via e-mail in September 2007 for data analysis. As a result, this analysis came to the following conclusions: First, it was found that 29.9% of total respondents took in charge of health promotion projects, and 26.9% respondents considered it very necessary to be responsible for the health promotion projects(56.0% considered it necessary). Almost half respondents considered nonsmoking assistance most desirable task(48.4%) and foremost demanded(50.5%) out of all current health promotion projects, 39.8% respondents answered that they could carry on health promotion task, if assigned, after completing occupational training course. Second, it was found that 39.3% respondents acquired other licenses and qualifications than certificate of registered dental hygienist, and their medical licenses or qualifications included certificate of nursing assistant(18.7%) and certificate of social worker(11.8%) by category. Third, in terms of opinions on possible ways to facilitate health promotion projects, it was found that over half respondents considered it recommended to step up specialized education(56.9%) and prepare legal basis and administrative system(53.6%). Notably, 90.7% respondents considered it necessary to step up specialized education in health promotion. Fourth, in terms of opinions on participation in health promotion projects, it was found that almost half respondents(49.7%) considered it necessary and very positive for extending dental hygienists' works in the future. Moreover, in terms of reasons for sum positive answers, it was found that many respondents considered it helpful for appointment(41.8%) and contributing to capability development and job satisfaction(44.5%). In terms of opinions that sud, participation would be unnecessary, 29.7% respondents thought that nothing would be changed in their dental health projects even with reduced number of public health dentists, and 31.3% respondents thought that dental hygienists are professional manpower responsible only for dental health works. Finally, in terms of on-the-job training(OJT) related to health promotion, it was found that 92.9% respondents desired for OJT. In terms of experiences in OJT, 79.9% respondents answered that they never joined OJT course. In other words, only 20.1% respondents joined OJT courses for health promotion task, such as nonsmoking assistance(8.8%), health promotion FMTP training(2.2%), exercises(1.4%) and nutrition(0.6%).
