With the decrease of the agricultural population in Korea, the workers who is vulnerable to labor are increasing in agricultural industry because of aging, feminization of population. They are exposed in poor working environment with higher temperature and concentrations of dust, gas. Higher concentration of harmful gas and dust can cause chronic and acute disease to workers depending on exposure intensity and frequency. In order to improve the working environment in the livestock facilities, It is important to secure monitoring data of the thermal environment and the concentration of harmful gases and fine dust. Multi-point measurement was performed to analyze the regional environmental conditions in the pig rooms. When analyzing the working environment, video monitoring was conducted to analyze the concentration changes of ammonia, hydrogen sulfide and fine dust according to worker movement and work type. Ammonia and hydrogen sulfide monitoring result showed 1.5~2 times higher concentrations than other work when working in the pigs living zone, and 2~4 times higher than other work when working to increase the activity of pigs. In the case of fine dust, the result was 1.3 times higher than the worker's exposure standard in a specific work. The concentrations of gases and dusts from pig farms are not of concern for acute poisoning in normal work, but there is a risk of chronic respiratory disease if they are continuously exposed. Accordingly, there is a need for development of work environment monitoring device tailored to workers and preparation of alternatives.
Education has been emphasized as one of tools of realizing social equality, which has its base on the ideology of equal education opportunity. The Opportunity level of adult education is important in the meaning of social equality. but these days It is being inequality. so The objectives of this study were 1) measuring the opportunity level of adult education in Korea, 2) analysing the difference adult education level by gender, regions, 3) making out the gap of the its level by social educational agencies, 4) to suggest the way to improve the opportunity level of adults educations between adults by gender, regions. The followings are the results from the study: Adult education participation level were lower. Adult education participation level per adult education type showed higher participation at private institutes, lower at cultural center of community and school's human and material resources are not properly utilized in adult educational activities. By adult education participation level per gender and location, women have a higher participation level then men, and urban areas have a higher participation level then rural areas. In case of location, environment variables is most explanatory in adult education participation level. To strive for methods to activate school-oriented adult education activities and to develop political solution to ease the resources gaps for adult education investment among regions in order not to deepen environment gaps of adult education between urban and rural areas. For adult education activation, institution and bodies in charge of adult education should expand and discover hardware and develop and distribute software. Also, adult education specialists who operate and manage these hardware and sofeware efficiently should be recruited.
Farm themed restaurants is an initiation by the Rural Development Administration (RDA) in order to perpetuate and develop Korean traditional food-culture. This food business model contributes to the increase of local food consumption and non-farm income for rural communities. Thus, the purpose of this study was to investigate the visitor's expectations, perception and satisfaction on the farm restaurant management type in order to assist activation of farm restaurants. Farm restaurants were categorized into two types; restaurant style and experience style. The majority of subjects(67.9%) were experiencing their first time to dine at farm restaurants. Regardless of farm restaurant style, the subjects perceived that farm restaurants use high quality food ingredients. The degree of subjects expectations prior to visiting a farm restaurant was estimated by 7 Likert scales. The results show that most subjects had high expectations for using good-quality food ingredients such as ‘fresh food (restaurant style 6.25, dietary education style 6.02)’ and ‘environment-friendly food (restaurant style 6.07, dietary education style 5.91)’. Overall satisfaction of the farm restaurants was also high. The satisfaction of food scored 4.1 and the satisfaction of experience program scored 3.8.
This paper is a part of "A Case Study on The Dwellings and Settlement of Korean Immigrants to North-Eastern Province of China". Among various subjects from the study, this paper covers with the spaces and life style in the dwellings of Korean Immigrants. The purpose of this paper is to discribe how their dwelling culture has been moved and changed to a new environment. One rural village of Korean Immigrants named "Ch'ang-ts'ai" in Yen-pien Province was selected where we investigated more than 110 households. From the formal interview, I collect the data on the family structure, family economic state, dwelling spaces and its use, and dwelling facillities and furniture. From informal interview with key informants, I analyze how they have changed their dwelling spaces and life style since they moved here. Based on the analysis of the data, I conclude that major features of their dwelling and life style has been moved from Korean penninsula, specially from 'Hamkyong' Province where their ancestor has lived. This features are summarized as follows: a. Dwelling spaces and its functions are simillar to typical dwelling type of Hamkyong Province. b. They use "Chong-ji" for both a cooking space and a major living space. c. They have a life style of sitting on the floor. d. Bedrooms are differentiated with male and female. e. Most of their dwelling facillities and furniture arc different from those of Chinese in the same province. Since they immigrated, there has been some social changes which could influence on making their dwelling culture. But they have preserved their cultural identity on their dwellings and life style. So I suggest that the dwelling culture of a society would be seldom changed by immigration, as long as they will be given similar conditions such as the independent ethnic community, the same ecosystem, and economical autonomy.
The present paper is concerned with the frequencies of G-6-PD deficiency acetylator phenotypes, hypocatalasemia and acatalasemia among Korean populations. The examination was carried out in the rural (Kyodong island, Moonmak Myeon and Yangyang Eup)and urban (Seoul) areas. The average frequency of G-6-PD deficiency in the total male population was 1.33%. A significant difference was observed among four areas. Tests on the color-blindness were performed in order to compara the two populations(Kyodong island and Seoul) and to obtain relationship between the color-blindness and G-6-PD deficiency. The frequency of color-blindness was 5.76% in the male rural population, and this rate was nearly consistant with that of the urban. The frequencies of the slow acetylator phenotype were 12.96% in Kyodong island, 10.36% in Seoul and 11.05% in Moonmak Myeon. Of the 3,004 persons investigated, no one has acatalasemia, but 10 cases of hypocatalasemia were found. The overall frequency was 0.33% which is slightly different from one area to another; 0.29% in Seoul, 0.27% in Kyodong island, and 1.15% in Moonmak Myeon.
The purpose of this study was to identify the factors that affected to physical functions, activities of daily living (ADLs) and instrumental activities of daily living (IADLs). The subjects for this study, 236 persons, 65 years and over, who were living at rural area in Chun-Cheon city. This survey was carried out from march 3rd to April 25th, 1998. The data was analysed by using SPSS PC+ program. The results were as follows. 1.The variables that were related to the conditions of physical functions were as follows; age, sex, educational level among the general characteristics; raising ways of money, monthly using money for life, states of pocket money, obtaining method of pocket money, state of weight, problems in mind, whether or not chronic illness among socio ㆍeconoㆍphysical conditions; the level of satisfactions in life, subjective condition of health among the subjective thinking ; controlling state in smoking and drinking of alcohol among the lifestyles for promoting health. But the variables for medical utilization were not related to the level of physical function. 2. The variables that were associated with the condition of ADLs were as follows; age among the general characteristics; monthly using money for life, working amount among the socioㆍeconoㆍphysical conditions; subjective conditions of health among the subjective thinking. But The variables for medical utilization, lifestyle for promoting health were irrelevant to the conditions of ADLs. 3. The variables that were related to the conditions of IADLs were as follows; age, educational level among the general characteristics; raising ways of money, monthly using money for life, resident type in the household, procurement method of pocket money, level of weight, problems in mind, wether or not chronic illness among socioㆍeconoㆍphysical condition; regularity of health checking among lifestyles for promoting health; kinds of utilizing medical agent among the variables about utilization patterns of medical agencies; subjective condition of health among the subjective thinking In this study, in the aged there were related factors of physical and life functions, were age, working amount, subjective condition of health.

HyangGyo had been built for teaching peoples as a place of educational practice, and also for the order and stability of country through Confucianism. This study analyzed and researched the building structure of Daejeong-HyangGyo in Jeju Island In Daejeong-HyangGyo, unique architectural characteristics are shown as they have been built in an island independent from the mainland. Also up-down system was well reflected in detailed architectural styles. The main temple of Daejeong-HyangGyo was built in the type of one-Chulmok(a subsidiary material of Gongpo and a piece of wood to support the eaves) of which ancon supports a purline from the center of a pillar and two-Ikgong(a piece of wood engraved to put on an ancon), but in the case of the lecture hall, its Gongpo(a piece of wood to support the eaves) was inferior in quality. In the case of Jeju abutments were used in main temples and fire walls were mostly used. In particular, their abutments are difficult to be observed in HyangGyo in the mainland. It is presumed that the abutment and the fire wall used in Jeju Island might be the best solution to protect structures from rain and moisture. To sum up, local characteristics and traditional rules were thoroughly reflected in Dajeong-HyangGyos built in Jeju Island from the aspect of arrangement and detailed style. In conclusion, it is significant that architectural styles, not to mention the other aspects of Jeju culture, were suitably adapted to Jeju Island.

The purpose of this study is to give some suggestions for the legal supplement of the regulation on the balcony expansion for the optimal use of apartment balcony. For the purpose, this study focused on the characteristics of spaces expanded to the balcony, in the plans supplied after the legalization of balcony expansion, comparing them by their location; the metropolitan area of Seoul Gyeonggi and the districts of the other areas. The 168 plans of apartments in the supplied by top 10 constructors in the metropolitan areas of Seoul and Gyeonggi, together with the 92 plans in the other smaller districts in 2006 to 2007 were analyzed with the tools of frequency and chi-square analysis. The result is as follows. (1) The region showed no difference in the plans of balcony; whereas the size, the position and access of the shelter explained some differences of balcony plan. (2) In wider plans, balconies were placed in all sides of plan-front, rear and side, and were remodeled to expand facing rooms. (3) The balcony expansion tended to increase the number of bays. (4) In almost cases, the living rooms were expanded to balcony. In smaller plans, the balconies were remodeled to supply supplementary kitchen space, splitting it from laundry. (5) The shelters were placed at the rear or side of plans, but the shelter facing room could be dangerous in case of fire. The balcony expansion, despite of legalization spirit to adopt diverse use of additional spaces for residents' needs, was only a tool for the space expansion. The amendment of the regulation is needed to accommodate these findings that the balconies should be identified by their function, that the front corridor-type balcony should be limited in length and magnitude, and that the shelter should be positioned with easy access.
In order to identify valuable factors for improving dietary quality of Korean rural elderly, the consumption frequency of food groups, dietary habits and health behaviors related to nutrient intakes of the elderly over 85 of Sunchang County were studied. The 171 subjects (61 males and 110 females) were chosen from Sunchang Province by stratified sampling. Among food groups, the consumption frequency of meat and fish groups influenced significantly on their nutrient intakes than the other groups. The subjects consuming more than 4 times per week of meat or fish had significantly higher nutrient intakes level than the other groups. The group consuming milk and milk products everday was higher in vitamin $B_2$ intake level than the other groups. Among dietary habits, the groups with good appetite and regular mealtime compared with the groups with low appetite and irregular mealtime had significantly higher nutrient intake levels. The family type was the determining factor of nutrient intakes. The subjects living with family members consumed higher nutrient intakes than the subjects living alone. The smoking and the alcohol consumption themselves did not affect nutrient intakes, but the subjects having alcohol consumption frequently more than once a day had lower nutrient intakes than the others. The group with dentures did not differ significantly from the without denture group in nutrient intakes; however, those who had chewing problems showed the lower nutrient intakes compared to those who did not have chewing problems. The subjects with more than two kinds of clinical symptoms had lower nutrient intakes than the subjects with less than two kinds of clinical symptoms. These results indicate that the identifying factors for desirable nutrient intakes of rural elderly were characterized as appropriate consumption frequencies of meat and fish, good appetite, living with family, regular mealtime, chewing without difficulty, and low incidence of chronic disease.
Xanthomonas oryzae pv. oryzae (Xoo) produces a putative effector, XoAvrBs2. We expressed XoAvrBs2 homologously in Xoo with a TAP-tag at the C-terminus to enable quantitative analysis of protein expression and secretion. Addition of rice leaf extracts from both Xoo-sensitive and Xoo-resistant rice cultivars to the Xoo cells induced expression of the XoAvrBs2 gene at the transcriptional and translational levels, and also stimulated a remarkable amount of XoAvrBs2 secretion into the medium. In a T3SS-defective Xoo mutant strain, secretion of the TAPtagged XoAvrBs2 was blocked. Thus, we elucidated the transcriptional and translational expressions of the XoAvrBs2 gene in Xoo was induced in vitro by the interaction with rice and the induced secretion of XoAvrBs2 was T3SSdependent. It is the first report to measure the homologous expression and secretion of XoAvrBs2 in vitro by rice leaf extract. Our system for the quantitative analysis of effector protein expression and secretion could be generally used for the study of host-pathogen interactions.
