This study was carried out to explore the illness-related activities of the menopaused women. To achieve such a purpose, sixty-six cases of the middle aged women were sampled the naturally and the artificially menopaused group respectively from 1st, Aug. to 31th, Aug. in 1988. For the collection of data, 1, 140 women aged between 45-54 were selected through stratified sampling techniques in urban and rural area. Among them the final subjects for analysis were restricted to only those who had experienced menopause naturally or artificially. And then, after control for age and education analysis was performed. The data was analysed by use of frequency, percentage, $X^2-test,$ t-test, Pearson correlation coefficiency and stop-wise multiple regression. The obtained results were as follows. I. As for the se1f-perception on menopausal symptoms, it was revealed than Korean women, neithe in naturally and artificially, accepted the change of menstruation itself as serious. This shows us that middle-aged women had positively receptive attitudes that the change of menstruation is follwed by amenorrhea. 2. The artificially menopaused group scored more than the naturally one: (I) on the self-control activities such as self-assessment, lay-consultation, fever check, pulse check and observation of vagina discharge, (2) on the self-decision activities such as hospital and pharmacy utilization, (3) on the self maintenance activities such as walking, aerobic, weight check, skin care, skin protect, calori control diet control, milk intake, vegetable intake, cold water drinking before meal, parasol use and BP check The above results lead us that the self care practices of the menopaused women revealed' coping wit I menopausal symptoms at the first level in community and must be developed by the adequate nursin intervention.

The Tartan, the representative check pattern and traditional costume of Scothand, is the most popualr checker which has inherited from the clans of the Scotch Highlands in the ancient times and continued to develop. It is a symbol of the Scotch culture and tadition and widely used in various ways according to status, birthplace purpose and use. Therefore, this study was intended to inquire into Tartan check. The purpose of this study attempted to make a systematic investigation of the characteristic of the Tartan check. the checker using vertical and horizontal lines which was the universal plastic element and inquire into it in terms of era, designers and combined works. By doing so, this study attempted to investigate the phase of the Tartan check in world fashion and further forecast the future of checker design applicable to the 21th-Century fashion. In addition it, attempted to investigate the features of Scottch costume unknown in our academic circles and inquire into the proless in while the Scottch has retained the originality of its own which suppressed by neighboring countries. This study could find out that the checker is the element of infinite applicability in the future. It is expected that the sophisticated and beautiful design using the checker will be presented by many Korean designer through the overall and systanatic study of the checker. On the other hand, to make an empirical study costume of other races, a comprehensive examination should be made of the social and cultural background against which locals are using their costume, through the survey of their real costume and on-spot research. It this respect, this study has some limitation in time and data collection. Besides the analysis of costume through materials and photos in museums as well as the study of cloth material and accurate colors was not con여cted in this in this study. This will remain to be study of in the future.

The purpose of this study was to compare convenience food purchasing behaviors and food habits. The study, which asked surveyed 131 female college students in Daejeon, in 2011, on how they used nutrition labels. The subjects were divided into two groups, in terms of the way they checked examined nutrition labels: a "Check" group(n=62, 47.3%) and a "No check" group(n=69, 52.7%). Reasons given for not reading nutrition labelings were "a habit of buying" for 72.2%, and "too small or rude" for 19.1%. The "Check" group reported higher interest in nutrition(p<0.001) and hygiene(p<0.01) than the "No check" group. Those who used the labels had higher cereal(p<0.01) and vegetable(p<0.01) consumption and a lower intake of fast foods(p<0.05). But however, most of the subjects(65.6%) chose by taste, at the time they purchased the convenience foods. The subjects considered "expiry date"(n=87, 66.4%) to be more important information on food labels than "nutrient composition"(n=11, 8.4%). The number of products whose nutrition labels were checked by over 50% was five out of 12. In conclusion, our study suggests that proper use of nutrition labeling may improve food choices and enable healthy dietary practices. Further efforts are needed to provide the public with nutrition education programs on how to read nutrition labeling. Modifying nutrition labels to make them easier for the public to understand should also be considered.

Recently scientists and engineers are developing a system to get waste heat of low-temperature level with advanced heat pump, which have not been used up to now. As the reason, it is necessary to examine capability of using waste heat which is raised up in the tunnel of subway out of widely distributed low-temperature waste heat in large cities. Therefore we surveyed thermal environment of the tunnel of subway in $S\check{o}my\check{o}n$, downtown of Pusan, from November 1995 to December 1996 and developed a program to predict the thermal environment of subway on the basis of experimental data and the geometries of tunnels. This paper has proved availability of waste heat of subway when the measured results obtained in subway in the winter time and the simulated results of thermal environment prediction program are compared, as well as has reported results of estimating reliability of the simulation program. As the result, the charateristics of thermal environment in the tunnel of subway in $S\check{o}my\check{o}n$ station in the winter time are to be followed; 1) temperature in the tunnel is about $10^{\circ}C$ higher than outside air temperature, 2) temperature change in the tunnel is less than that in the platform so that we may obtain stable heat source, 3) and when the measured results obtained in subway in the winter time and the simulated results of thermal environment prodiction program is compared, both results show similar tendency. Therefore, we confirm estimating reliability of the simulation program.

The objectives of this study are (i) to review current situations and problems of the occupational health care system with emphasis on reforming the organizations and services, (ii) to find out a disirable occupational health system model based on integration of the occupational health system and the general health system, and finally, (iii) to suggest policy implications in occupational health services in the light of objectives of the newly emerging national health insurance reform in Korea. The major policy implications of this study are as follows: 1. In the long-run, within the occupational health system, preventive occupational health services such as employees' physical check-up, working environment examination, etc should financially be integrated with industrial accident compensation insurance. Currently separately paying expenses for each different category of services by the owner of an enterprise should be disbursed once through the payment of contributions of industrial accident compensation insurance. And then, it is necessary to strengthen and expand the role and function of industrial accident compensation insurance to cover preventive occupational health services. 2. The occupational health system should be integrated with general health system for its effective management. For the short-term policy, it is necessary to eliminate fiscal and access barrier between industrial accident compensation insurance and national health insurance by means of ex post facto settlement of accounts. The duplication of employees' physical check- ups between under the health insurance program and under the industrial health services must be coordinated in a manner either through mutual authorization by the two parties concerned or through merge into the health insurance. 3. The intent of current employees' physical check-up system focused on detection of occupational diseases, should be converted to an idea of medical surveillance system or biological moritoring system. The introduction of medical surveillance or biological monitoring system is a necessary condition to build a positive, effective and inexpensive occupational health care system.

Various surface grinding experiments using resin bonded diamond abrasive wheels are carried out for tungsten carbide materials in order to minimize the damage on the ground surface and to purse the precise dimension compared to conventional grinding machine. When grinding quality is constant, theoretical grinding effect is changed according to the speed of workpiece. Accordingly, grinding forces, which are Fn, Ft, were analyzed for the machining processes of tungsten-carbide material to obtain optimum grinding conditions. Brief investigation is carried out to decrease the dressing efficiency of resinoid bonded diamond grinding wheel to grind tungsten-carbide. Truing is also carried out to provide a desired shape on a wheel or to correct a dulled profile. High quality in dimensional accuracy and surface are often required as a structural components, therefore 3-points bending test is carried out to check machining damage on the ground surface layer, which in one of sintered brittle material. From this experimental study, some useful machining data and information to determine proper machining condition for grinding of tungsten-carbide materials are obtained.

This study was undertaken to provide useful information to restaurant managers by analyzing eating out behavior and the diverse needs and wants of the people residing in the Seoul area. four hundred twenty-seven(427) people were sampled for this study and classified into three groups : housewives, salarymen and college students. The results of this study are as follows : (10 Among the groups, there were significant differences in general eating out behavior such as 'frequency' 'preferred food style' and 'who pays the check' among others. (2) The study showed housewives listing 'special occasion' as 'taking care of meal' (3) All groups considered 'price' as especially important. (4) When selecting a menu item, taste was considered most important by all groups. Housewives showed nutritional value to be important while salarymen chose the same item as companions an college students showed 'portions' and 'price' to be important. (5) degree of satisfaction of restaurants were found to be low with items such as ' price'. 'range of menu choices' and 'courteousness of employees' being relatively low.
