Chinese cabbage Kimchi is a traditional fermented food and a numerous variety of Kimchies are produced in Korea. Most of Kimchis are produced on a small scale in the home for individual household use and recipes of Kimchis are deeply embedded in the individual cultures. Currently, however, factory-produced Kimchi is becoming popular by industrialization and changes of life style. This study was conducted to find out recipes of traditional Kimchis which are known delicious in Pusan and its environs and to develop a Kimchi with high quality. The characteristics of Kimchi recipes surveyed in Pusan and its environs are as follow: 1) Large amount of red pepper, garlic and anchovy sauce was used, which made Kimchi hot and spicy. 2) Extracts of dried anchovy or shrimp, or pear and onion juice was used to mix red pepper power. 3) Selection of good quality of Chinese cabbage and red pepper was very important step to determine quality of Kimchi. Furthermore, a numerous variety of submaterials added in Kimchi may also contribute to the high quality of Kimchi. 4) Salt concentration of Kimchi was around 2%, which was lower than it was generally known. Through this survey, it was suggested that maintaining low salt content of Chinese cabbage during salting make Kimchi crispy and juicy.

In a bid to avoid the economic loss resulting from traffic jam in urban area, a deep underground road at 40 m depth has been considered and the first class disaster prevention facilities shall be applied according to domestic guideline. Automatic-monitoring fire extinguishing system designed to use for fire fighting has been widely applied at home and abroad. Recently development and commercialization through theoretical and experimental research to apply to road/railroad sector have been underway. Based on such performance of automatic fire extinguishing system, technical/economic analysis of existing water spray systems was conducted and as a result, it has demonstrated the superiority in terms of fire suppression as well as in cost efficiency. Then to commercialize this system, more diverse studies that will incorporate the characteristics of domestic tunnels are needed and should the system be promoted through institutional improvement, it's expected to become one of the advanced nations with own original technology in a life safety system industry throughout the world.

The purpose of this study is to investigate the relations between housewife's self esteem and attitude toward household work its satisfaction and to find out how independent variables(housewife's age, education level, employment, household work helper, type of family) have effect on the two dependent variables. The measurement of self-esteem was based on the self-concept test standarized by Jung Won Sick, reformed the Fitts measurement for Korean Society. In order to measure of attitude toward household work and its satisfaction, based on the previous research, researcher made the measurement . the research was conducted on 234 housewives in Seoul in September 1984. Data was analyzed by percentage, mean, frequence analysis of variances, Pearson's correlation coefficient. The result can be summarized as following. 1)Over on half of housewives have high self-esteem comparatively. 2) Age and education level were variables to have influence n the attitude toward household work. 3)The attitude toward household work and its satisfaction comparatively were high. 4)Education level and type of family were variables to have influence on the attitude toward household work. Education level, employment and household work helper were variables to have influence on the satisfaction of house hold work. 5) Level of Self-esteem has influence on the attitude toward household work and its satisfaction. The higher level of self-esteem was, the higher becomes the score of the attitude toward house hold work and its satisfaction. Following suggestions can be extracted form the results of above study. 1) research of housewife's self-esteem didn't established a setted theory yet. I think, therefore, it requires deeper study about housewife's household work look upon as her occupation and relation between the household work as her occupation and her self-esteem in this area. 2) Population and sociological variables, used in this study, hardly influenced on self-esteem, the attitude toward household work and its satisfaction. Also the result didn't correspond with one another. So I think it requires need of further study how psychological and family function variables will have influence on housewife's self-esteem, the attitude toward household work and its satisfaction. 3) To recognized the value of household work objectively, many researchers tried to investigate of economical value of household work, But if housewife can realize her self-actualization through household work, it requires the study that try to objectively not only estimate the economic value of household work, but also the contribution of the aspect of family psychology.

The purpose of this study is to search how to promote health and improve nutrition and health care of the elderly people in rural area. Behaviors for health promotion and habits against health risk were surveyed. Dietary management was analyzed for surveyed nutrient intake by 24 hr -recall method. 242 subjects were collected in 12 cities or counties in Gyeonggi Province and 20 elderly people (10 male and 10 female) were selected out of 1 village in each district. Questionnaire for health behavior and dietary management was carried out by trained interviewers. Statistical analyses were made by SAS (version 8.1) and Chi-square tests and General Linear Models were used. Characteristics of the elderly people were 61-74 year-olds (68.2%), elementary school educated (78.4%), with spouse (51.7%), monthly living cost of 500-1,000 thousand won(43.4%), and monthly pocket money of 50-100 or 100-200 thousand won(33.5%, 26.5%). 41.4% of the subjects checked up medical examination regularly. The alcohol drinking status was significantly different according to gender: high no-drink rate of female (52.5%) and low no-drink rate of male (25.6%). Kinds of disease were different according to gender: higher proportion of cardiovascular disease(46.3%) and diabetes mellitus(8.1 %) in male and joint lumbago neuralgia(44.4%) and osteoporosis(8.6%) in female. Gastrointestinal complaints were nausea (69.0%) and chronic indigestion (17.8%). Constipation (12.0%) and vomiting (4.3%) were more frequent in female. Dietary management was good (3 meals per day: 93.4%., dining with family: 72.4%, regular mealtime: 72.4%, and 3-4 times of snacks per week: 44.9%) except side dish taking of 3-4 kinds only. However, almost one-third of the female elderly ate alone (30.6%) which was well compared with one-fifth of the male (19.7%). And food and nutrients intake were not significantly different according to gender except that male elderly's intake of energy and protein was lower than that of female's. The surveyed subjects had no difficulties in Activities of Daily Living (ADL), but some female elderly had some difficulties with Instrumental Activities of Daily Living (IADL) like working at home, using transport, and going shopping. These results suggest that low quality of life linked with low economic status of the rural elderly and that congregate meal at village hall would be required for the female elderly eating alone. For the undernourished male elderly, it would be needed to provide snacks and to establish nutrition and health surveillance system.

To verify welfare needs, rural health and environmental factors were compared between agricultural and nonagricultural groups over the past 10 years. Based on a survey of rural life by the Rural Development Administration, whose sample included agricultural (72.8%) and nonagricultural (27.2%) groups, all factors were analyzed using SAS ( 9.3). For rural home heating, the use of oil boilers (77.2%-78.0%) decreased (53.0%-53.7%) over the same period, whereas that of electric boilers increased (21.9% and 13.5% for agricultural and nonagricultural groups, respectively). The joint water- supply increased, and the use of flush toilets (52.4% to 84.5% in the agricultural group and 64.6% to 81.4% in the nonagricultural group) and hot-water bathing was higher in the agricultural group (79% to 92.6%) than in the nonagricultural group (72.2% to 87.6%) at the p<0.001 level. Incineration accounted for the largest portion of household waste until 2006, when it was replaced by other treatment methods such as the pay-per-treatment option (44.4% and 68.3% in the agricultural and nonagricultural groups, respectively) (p<0.001). Garbage disposal in 2001 was mainly burial or animal feed, but separate collection increased in 2010 (42.2% and 64.3% in the agricultural and nonagricultural groups, respectively) (p<0.001). The self-perception of health was lower in the agricultural group than in the nonagricultural group (2.96 to 2.74 on a five-point scale in the agricultural group and 3.07 to 2.98 in the nonagricultural group). Drinking decreased less in the agricultural group (criteria: one point once a week,; 1.48 to 1.20) than in the nonagricultural group (1.13 to 0.80) at p<0.001, and a similar pattern was found for smoking (p<0.001). Health screening decreased in the last 10 years (scoring based one point/1-2 times per year,: 0.94 to 0.64 in the agricultural group and 1.08 to 0.69 in the nonagricultural group;p<0.01). These results indicate that various health and environmental factors were less favorable to farmers except for bathing in comparison to nonagricultural living in the same area. This suggests that people in agriculture are less likely to live and work in favorable environments than those outside the sector and thus indicates a need for more attention to the national health welfare system for farmers for systematic realization.

As one of the solutions to deal with economic loss caused by traffic congestion in metropolitan area, a deep underground road has been planned and implemented at home and abroad. The part of them has been pushed ahead with a double-deck scheme which has an advantage in constructability and cost efficiency comparing to traditional road tunnel. However, the double-deck tunnel has a lower floor height than the general road tunnel due to the special structure used as the upper and lower lines by installing the middle slab on one excavation section. Therefore, it is relatively weak against fire accidents and ventilation problems occurring in tunnels. Thus study to develop the life safety system optimized to a double-deck tunnel has been systematically carried out in order to overcome their weak point. In this study, automatic monitoring fire extinguisher (AMFE) is developed to suppress a fire and prevent its spread at early stage of tunnel fire, conducting the performance test through vehicle fire tests as verification. The tests were conducted with AMFE being 30 m apart from the vehicle and 10 m apart from engine room. As a results, it was confirmed that AMFE enables to suppress a fire and prevent its spread in both cases.

This study compared the food habits and attitudes towards dietary life culture in types of feeding management, gender and grade. The subjects were 352 elementary school students who lived in Seocheon, Chungnam. The independently managed school students were better than jointly managed school students in food habits (p<0.05). In skipping school meals, upper grade students were skipped more than lower grade students (p<0.05). In rate of eating school meals, boys were faster than girls (p<0.001). The independently managed school students and the jointly managed school students were different on distasteful food. Boys disliked vegetables and girls disliked cereals and beans (p<0.05). Upper grade students ate more well-balanced meals than lower grade students (p<0.05). As for the question 'what you will do if the distasteful foods are provided through school meals', they responded. the highest percent of students, 'I will try once or twice'. And the response 'I have them for health' was higher independently in managed school students than the jointly managed school students (p<0.05), girls than boy (p<0.05), and the lower grades than the upper grades (p<0.05). As for the question 'what you will do if the distasteful foods are provided, after the guide for school meals was performed', the response, 'I will make an effort to have it' accounted for the highest percents, and there were differences in lower grade students who were high percents than upper grade students (p<0.01). As for the recognition for unbalanced diets, most of the students recognized that it is a 'bad habit'; the girl students accounted for more percentage than boys (p<0.05). The criterion of food choice were different in gender and grade (p<0.01). As for the factor of influences for the food habits formation, lower grade students were 'school education' and upper grade students were 'parents' (p<0.05). Thus, the systematic guide for proper intakes of nutrition should be performed. Also, the time when students can be educated by an expert of nutritional education, which is connected with school meals and students can grow healthily.

Background: One of the most urgent issues following the accident at the Fukushima Daiichi nuclear power plant (FDNPP) was the remediation of the land, in particular, for residential area contaminated by the radioactive materials discharged. In this study, the effect of decontamination on reduction of ambient dose equivalent outdoors and indoors was evaluated. The latter is essential for residents as most individuals spend a large portion of their time indoors. Materials and Methods: From December 2012 to November 2014, thirty-seven Japanese single-family detached wooden houses were investigated before and after decontamination in evacuation zones. Outdoor and indoor dose measurements (n = 84 and 114, respectively) were collected based on in situ measurements using the NaI (Tl) scintillation surveymeter. Results and Discussion: The outdoor ambient dose equivalents [$H^*(10)_{out}$] ranged from 0.61 to $3.71{\mu}Sv\;h^{-1}$ and from 0.23 to $1.32{\mu}Sv\;h^{-1}$ before and after decontamination, respectively. The indoor ambient dose equivalents [$H^*(10)_{in}$] ranged from 0.29 to $2.53{\mu}Sv\;h^{-1}$ and from 0.16 to $1.22{\mu}Sv\;h^{-1}$ before and after decontamination, respectively. The values of reduction efficiency (RE), defined as the ratio by which the radiation dose has been reduced via decontamination, were evaluated as $0.47{\pm}0.13$, $0.51{\pm}0.13$, and $0.58{\pm}0.08$ ($average{\pm}{\sigma}$) when $H^*(10)_{out}$ < $1.0{\mu}Sv\;h^{-1}$, $1.0{\mu}Sv\;h^{-1}$ < $H^*(10)_{out}$ < $2.0{\mu}Sv\;h^{-1}$, and $2.0{\mu}Sv\;h^{-1}$ < $H^*(10)_{out}$, respectively, indicating the values of RE increased as $H^*(10)_{out}$ increased. It was found that the values of RE were $0.53{\pm}0.12$ outdoors and $0.41{\pm}0.09$ indoors, respectively, indicating RE was larger outdoors than indoors. Conclusion: Indoor dose is essential as most individuals spend a large portion of their time indoors. The difference between outdoors and indoors should be considered carefully in order to estimate residents' exposure dose before their returning home.
