This study was to examine the effects of economic, social, psychological, and marital resources on the relationship between retirement related stress and life satisfaction among the retired husbands and their wives. Economic resources included actual income, the amount of reduced income after retirement, and perceived adequacy of income, while social resources consisted of the supports from children, relatives, friends and neighbors. Psychological resources constituted sense of mastery and marital resource was measured by the emotional supports from the spouse. Data from 178 couples in Seoul revealed that retirees and their spouse perceived retirement as a very stressful extent, with husbands viewing their retirement as more stressful than their wives. The retirement related stress was found to be the most significant predictor on the life satisfaction of the couples. For retired husbands, life satisfaction was closely associated to sense of mastery and supports from children and relatives. The health status, perceived adequacy of income, sense of mastery, and supports from children and relatives were related to life satisfaction for wives. Therefore, the effects of personal resources on life satisfaction were smarter than that of retirement related stress for both retired husbands and their wives. Along with discussions, implications for retirement education and suggestions for future study are provided.

The present study has been conducted economic analysis through actual operation of electric heat pump (EHP) and gas engine driven heat pump (GHP) which are installed at the same building in the university. Cost items, such as initial cost, annual energy cost and maintenance cost of each system are considered to analyze life cycle cost (LCC) and economical efficiencies are compared. The initial cost is considered on the basis of actual cost, and annual energy cost is converted into the cost after measuring electricity and gas consumption a day LCC applied present value method is used to assess economical profit of both of them. Variables used to LCC analysis are electricity cost escalation rate, natural gas cost escalation rate, interest rate, and service lives when each of them are 4%, 2%, 8%, and 20 years. The result shows that EHP (148,257,306 won) is more profitable than GHP (161,239,296 won) by 8.05% (12,981,990 won).
Farmland spatial data are needed as a basic information in conducting rational use of farmlands in regional scale. This study develops a method that can be used to make up such farmland spatial data in a simple way and to develop a technique to manage them in a unitary way, and examines the effectiveness of the technique by applying it to the case area. A method that Web-Service Raster Image and Digital Cadastal Map can be utilized as a base map was devised. It was designed applying the vector system, in which one lot of farmland is area unit. Raster image and field survey data were combined to increase the accuracy of data. The lot boundaries of the existing boundary map were adjusted to the shapes of actual farmlands using GIS edition function. A proper farmland use classification system to the area characteristics was established and data obtained from the field survey were coded. Usually it is very difficult to identify the size of one lot of actual farmland in the existing space data, based on the results of the case study, the result map showed actual topography very realistically. Also the frequently occurring lot divisions and the serious topographical modifications by natural disasters frequently have made it impossible to survey farmlands on the catastral map in the field. But the final map had a great usefulness in that it may solve such problems by expressing the filed survey results graphically.

The purpose of this study was to survey the actual condition of the Middle School Students on a Drug. In this study, 500 middle school students in Seoul response to a questionnaire which is composed to analyse two categories, i.e. general facts, the actual condition of drug use (the frequency of drug use, the degree of perception on drugs, the people using a drug surrounding the degree of purchase on drugs). And the students are classified by satisfactory degree on their home backgrounds, satisfactory degree on their school life, and school record. The data is analysed by means of frequency, percentage, chi-square test and Pearson's correlation using the $SPSS-PC^+$ package program. The results of this study were as follow : The frequency of drug use except a alcohol and the degree of perception on a drug among female students are higher than among male. The female students are more permissive on the drug use and they are also tend to think more easily the purchase of a drug. The frequency of drug use and the degree of perception on drugs are higher in the group of the lower satisfactory degree on their home background. Especially, there are many people using drugs surrounding the students in the lower group. The frequency of drug use and the degree of perception on drugs are higher in the group that has the lower satisfactory degree on school life. The students in the group having low school record have more dangerous thought about the use of drugs than the students of high record. The degree of perception on a drug is higher in a higher group, and the students in a higher group also think more easily the purchase of drugs. The percentage of students using drugs are not high, but the high percentage of students are interested in the drugs and they have permissive attitudes on drugs. Thus, the preventive education for drug abuse must be done rapidly.
Research on the actual state of healthy Korean food menu items made from environmentally-friendly organic foods showed that 65.6% of subjects had experience of purchasing environmentally-friendly organic foods, and both genders chose 'expensive but reliable' as their prime reason for purchasing. Having no experience of purchasing environmentally-friendly foods constituted 34.5% of respondents, and the reasons were 'high price' and 'finding no difference from ordinary food'. Research on awareness of healthy Korean food menu items made from environmentally-friendly organic ingredients showed that both men and women thought the given menu items were 'fresh' but had little awareness of other factors such as 'good value for price', 'good visual style' and 'various recipes'. Regarding development prospective of environmentally-friendly organic foods, the number of subjects who answered positively was 405 (93%), which indicates that most research subjects showed positive attitudes. Top-selling menu items in the grain section were Sundubu-jjigae, Dubu-kimchi and Jeonju-bibimbap, and pajeon took first place in the vegetable selection. Moreover, Imjasu-tang showed high scores in the meat section. Furthermore, research on menu selection showed that menu selection was usually dependent on 'the price of menu (3.86)', 'fresh ingredients (4.03)', 'harmony of color (3.65)' and 'mood of the day (3.25)'. Research on menu selection revealed that 'quality of food' factors had the greatest influence upon preference and purchase intention for environmentally-friendly organic foods. Visual and psychological factors and values had significant an effect. Therefore, the food service industry should use this study as a source to develop menu items, by considering quality and visual factors. In addition, there should be various research performed on marketing strategies about menus from using environmentally-friendly organic foods and high value products.
The purpose of this study is to analyze the actual condition of the already established rural theme park, draw the weak and strong points, and come up with an efficient performance plan for Changwon Persimmon Theme Park through the benchmarking of the best overseas case. According to the analysis, it is necessary to introduce a facility and a program for family customers as a plan for promoting Changwon Persimmon Theme Park. It is required to secure safety through public operation and management, improve scalability of the facility through the establishment of multi-functional complex facility, and come up with a plan for operating a special program associated with local resources. Therefore, this study drew three activation factors: the establishment of operation and management system, the development of operation contents by facility, and the establishment of operation in each area. First, to establish the operation and management system, it is necessary to classify the organization of the theme park into the operation business area and into operation & management area by job function. Secondly, it is necessary to establish a special program in consideration of space and facility, suggest a differentiated plan for operation contents, and create a facility operation plan and program for Changwon Persimmon Theme Park. Lastly, to operate and manage Changwon Persimmon Theme Park smoothly, it is necessary to set the theme park space as open collaboration space which the local residents can share and participate in by avoiding the conventional administration-based business performance and operation. This study suggested the plan for establishing an operation and management system for Changwon Persimmon Theme Park and its operation, the establishment of a special program, a business performance strategy, and the use of internal and external spaces of the theme park.

The appearance of the large distribution facility of large enterprise putting first reaches get to the various effect until change of leisure life and life pattern of the consumers from the distribution industry of the interior of a country. Competition of the distribution facility upgrade of the distribution facility and it shows the aspect which becomes the semi-department store, and construction cost is appearing different in proportion to each form or scale. Therefore, purpose of this study was to facilitate amicable construction progress between the owner and the builder through estimating the proper construction cost. This study investigated and analyzed the actual cost of 15 domestic distribution facilities and these datums were used to estimate the proper construction cost. This cost shows that from new project accomplishment through analysis of prediction construction cost for feasibility study from initial plan and design step and can be utilizable elementary data bH decision method to whether or not to propriety of distribution facilities business.
Analytical models were developed and seismic behaviors were analyzed for a three-story stone pagoda at the Cheollyongsa temple site, which was damaged by the Gyeongju earthquake of 2016. Both finite and discrete element modeling were used and the analysis results were compared to the actual earthquake damage. Vulnerable parts of stone pagoda structure were identified and their seismic behaviors via sliding, rocking, and risk analyses were verified. In finite and discrete element analyses, the 3F main body stone was displaced uniaxially by 60 and 80 mm, respectively, similar to the actual displacement of 90 mm resulting from the earthquake. Considering various input conditions such as uniaxial excitation and soil-structure interaction, as well as seismic components and the distance from the epicenter, both models yielded reasonable and applicable results. The Gyeongju earthquake exhibited extreme short-period characteristics; thus, short-period structures such as stone pagodas were seriously damaged. In addition, we found that sliding occurred in the upper parts because the vertical load was low, but rocking predominated in the lower parts because most structural members were slender. The third-floor main body and roof stones were particularly vulnerable because some damage occurred when the sliding and rocking limits were exceeded. Risk analysis revealed that the probability of collapse was minimal at 0.1 g, but exceeded 80% at above 0.3 g. The collapse risks at an earthquake peak ground acceleration of 0.154 g at the immediate occupancy, life safety, and collapse prevention levels were 90%, 52%, and 6% respectively. When the actual damage was compared with the risk analysis, the stone pagoda retained earthquake-resistant performance at the life safety level.
The goal of this study was to provide basic data for the future development of dietary life education in elementary schools by understanding the current conditions of the program after the execution of the Dietary Life Education Support Act. We conducted a survey to understand dietary teachers' recognition of dietary life education in elementary schools. We found that teachers' recognition was low and that dietary life education in elementary schools is still carried out indirectly by focusing on nutrition knowledge. Dietary life education is carried out during lunch time and dietary life-related class hours. However teachers of lower class levels did not have any practical subject related to dietary life and responded that a lack of time devoted to dietary life education was the biggest problem with the program. Most teachers responded that dietary life education in elementary schools is necessary for the formation of students' sound dietary habits, and that the development of a system of teachers directly responsible for dietary life education is necessary. In the past, dietary life education has typically been carried out at home, but now schools are required to play a role because of family nuclearization and the increase in working couples. Therefore, to revitalize dietary life education programs in elementary schools according to the Dietary Life Education Support Act, we suggest more systematic and segmentalized studies.

The purpose of this study was to examine resting metabolic rate (RMR) and thyroid hormonal (TSH, $T_3$, and $T_4$) changes following weight loss by diet with regular exercise in obese women. The subjects of the present study were 7 women who were above 30% body fat. The subjects arrived into the laboratory in the morning after 12 hour overnight fasting. All subjects measured RMR, % body fat, and fat free mass at weight loss program start time, after 4 weeks and after 8 weeks. All the RMR values were expressed as absolute value (kcal/day), absolute value/FFM (kcal/day/FFM), and absolute value/BSA (kcal/$m^2$/hr), and were calculated predicted RMR value minus actual RMR value. Also, correlation of blood thyroid hormonal (TSH, $T_3$, and $T_4$) secretion and RMR were analyzed. There were significant differences in weight, % body fat, and BSA following diet with exercise (p<0.05). Also, there was a difference between predicted RMR and actual RMR value following weight loss (p<0.05). We also examined the hormonal changes according to weight loss. After weight loss, the level of TSH and $T_4$ were higher than before. But there were no significant differences. Also, the level of $T_3$ was lower than rather before but there was no significant difference. Among the anthropometric factors, FFM was highly correlated (r=0.761) with actual RMR value before weight loss. Also, there was a correlation (r=0.771) with actual RMR value after weight loss. Therefore, actual RMR expressed as FFM increased in weight loss program by diet with exercise. There were no changes in the level of thyroid hormonal TSH and $T_4$.
