The objectives of this study were to explore theoretically the factors that were associated with role conflict of rural extension educators, to investigate the consequences of this conflict, and to suggest possible solutions to the role conflict. This study was carried out through literature review. The findings from this study were as follows : 1) The causes of role conflict were divided into individual characteristics and social or organizational characteristics. Existing research papers examining the cause of rural extension educators' role conflict had focused mainly on individual characteristics. Therefore, social characteristics of the role conflict should be included in future research activities. 2) The consequences of role conflict were made up of individual dimensions and organizational dimensions. However, pervious researches on rural extension educators' role conflict had dealt with the individual dimensions only. Therefore, the consequences of organizational dimensions should be added to future researches. 3) Revision of roles and job specifications, developing professional competencies, and raising achievement motivation were some of the possible solutions to rural extension educators' role conflict. These solutions, if managed effectively, may improve the performance of extension organizations, as well as that of the individuals by solving the role conflict of rural extension educators.

This study was to develope the functional work clothing for livestock farmers. Major demanding performances for livestock work clothing are anti-soil and anti-bacterial properties. On surveys, functional fabrics that have anti-soil, anti-bacterial and waterrepellent performances were developed and the work clothing that have adaptability to body movements were manufactured. The designs of livestock working clothes were two piece and one piece with rubber bade in waist. The thermal responses of subjects wearing the winter working clothes for stock farming worker were measured in the climate chamber($17^{\circ}C$, 40% R.H.). The main results were summarized as follows: Total body weight loss was smaller and the mean skin temperature was higher in developed clothes than the market product. Clothing micro-climate of developed clothes was lower than the market clothes. Subjective sensation did not have significant differences. From the results of various evaluation, developed garments for livestock workers showed better efficiency than the market product.

This paper investigates the current status of Jeju special self-governing province (JSSGP)'s water infrastructure and recommends directions for improvement. JSSGP relies on groundwater for most of its water resources. Recently, water usage has been steadily increasing due to the increase of residents and tourists while the quality of groundwater has been steadily worsening. Deterioration in water quality of groundwater can be seen through the increase in concentration of nitrate nitrogen and microorganisms. To overcome such problems, water consumption must be reduced by water demand management in all fields including residential and agricultural water use. The quality of water resources should be preserved through the management of pollutants. For efficient management of water resources, great efforts should be made to reduce the leakage rates in household and agricultural water, which is currently at the highest level in the country. Furthermore, diversification of water intake sources other than groundwater is needed, especially for agricultural water supply. For water and sewerage facilities, compliance with drinking water quality standards and discharge water quality standards must be achieved through the optimization of operation management. This process requires recruiting professionals, improving existing workers' expertise, and improving facilities.

The large bumblebee $Bombus$ $terrestris$, indigenous to Europe and adjacent areas and used extensively for high-value crop pollination, has been artificially introduced to several parts of the world. Here we show the occurrence of interspecific hybridization between the bumblebee species $B.$ $hypocrita$ $sapporoensia$ and $B.$ $terrestris$ under laboratory conditions. The mating and oviposition percentages resulting from the interspecific hybridization of a $B.$ $terrestris$ queen with a $B.$ $h.$ $sapporoensis$ male were higher than those resulting from the intraspecific mating of $B.$ $h.$ $sapporoensis$. Furthermore, a competitive copulation experiment indicated that the mating of $B.$ $h.$ $sapporoensis$ males with $B.$ $terrestris$ queens was 1.2-fold more frequent than the mating of these males with $B.$ $h.$ $sapporoensis$ queens. The interspecific hybridization of a $B.$ $terrestris$ queen with a $B.$ $h.$ $sapporoensis$ male produced either $B.$ $terrestris$ workers or the $B.$ $terrestris$ male phenotype, and the hybridization of a $B.$ $h.$ $sapporoensis$ queen with a $B.$ $terrestris$ male produced $B.$ $h.$ $sapporoensis$ males. Our results indicated that interspecific hybridization occurred between $B.$ $h.$ $sapporoensis$ and $B.$ $terrestris$. These results suggest that such hybridization will have a negative competitive impact and will cause genetic contamination of native bumblebees.

The operation of a five day workweek seems to be increased continuously, Many city-workers will make good use of their spare time and search after a lot of devices that can seek for the maximum value of leisure utility. The demand of potential customers that want to enjoy weekend in farming villages is coming out greatly. That is, the condition of users that will travel the farming villages is getting better. But the actual states of farming villages are not ready in many parts yet. Therefore we must activate the tourist attraction in farming villages that can be satisfied the city-workers' expectation. And after making the sightseeing environment infrastructure, we must develop the programs intimate with environment, improve the sightseeing agricultural management and consolidate various systems as soon as possible. So in this study, after investigating the demand preference degree of city-workers, I tried to grope an activation plan with the base which will reach. Being more urgent what more, not the simple sightseeing agriculture that the farming experience was the focus of, but it is very important to develop the program of environment sightseeing agriculture. It will lay the stress on playing and education culture which city-workers can enjoy and experience. And with constructing the base facility like a city form, we must develop cheap and various goods and the execution of modernized weekend farms. For this, first the consciousness conversion against the customer management of farmers must precede and the change of government policy and the support polity is important. I hope that this study with the five-day workweek has the chance to contribute in the economic growth of farming villages and efficient use and management of the natural environment resources through the activation of sightseeing agriculture.

Background: Work-related musculoskeletal disorders are accumulative disorders that are most frequently found in agricultural farmers. The purpose of this study was to investigate factors that affect symptoms resulting from work-related musculoskeletal disorders among Cambodian farm workers working in fruit plantations in the eastern region of Thailand. Methods: The Nordic Musculoskeletal Questionnaire, Rapid Upper Limb Assessment, and Hazard Zone Jobs Checklist techniques were used to interview 861 farmers who participated in the study. Results: The data showed that men who had been working for >10 years were more at risk of neck pain than those working for <1 year with adjusted odds ratio (aOR) 1.66, 95% confidence interval (CI) (1.90, 14.5). Among women those who had been working for >10 years experienced lower back pain with aOR 8.13, 95% CI (1.04, 63.74), compared with those who had been working for <1 year. Men whose tasks required raising the arms above shoulder height had a risk factor contributing to neck pain of aOR 1.68, 95% CI (1.08, 2.61) when compared with those who did not work with this posture, and women had aOR 1.82, 95% CI (1.07, 3.12) when compared with those who did not work with this posture. Conclusion: Based on the results of this study, it is recommended that work-related health conditions are monitored in migrant plantation workers to reduce the risks of musculoskeletal disorders.

With the increase of pesticide consumption, not only pesticide handling population would grow greater but also the chances to be exposed to the pesticides would be also increased. Thus, safe use and handling of the pesticides are becoming more important and serious in these days. The pesticides are well known to most pepole, however there are very limited number of persons who have correct understanding of chamicals. Intoxication cases caused by pesticides have been reported very rarely through the mess media, even they were lack of scientific evidences. In this paper, problems related to pesticide manufacture, transportation, storage, sprays, and residues and their countermeasures were discussed in connection with public health and enviromental aspects. Acute intoxication cases by pesticide handling might be caused accidently either through manufacture, marketing, transportation, or spraying. Safety aspects of workers in manufacturing plants include not only exposure to toxic chemicals, but also posibilities of of explosion and brought about by pesticides and their diluents. The problems of water pollution by waste chemicals from the manufacturing factories were discussed. Packing and loading methods of pesticides for transportation are considered in safety scheme and discussions are given in association with traffic accidents. With regard to warehouse, the pesticide storage, location structure, keepers, and standing materials for emergency are concerned with safety aspects. Concerning the spraying of chemicals, there are some problems to be discussed about clothes, spray equipment, wind direction, spray period, and spray workers condition. After the spray, treatment of used containers, remainder of Pesticides, and spray tools are also discussed. For the dissolutions of problems on public health and environmental danger arising from pesticide residues, there are two legal sanctions; 'Pesticide Tolerances' and 'Pesticide Safe Use Standards'. These regulations are legally effective, however, some problems still remain in practices to implement the acts properly, because these provisions are followed by the far mers mostly. With these regards, most problems are concerned with various sectors and persons, affecting public health and environment from the producers to the end users and consumers. As a whole persons concerned with pesticides, every possible effort has to be assembled to protect hazards from the chemicals. For the foremost place, special training and education are required for managing groups; such as factory managers and agricultural extension workers who are responsible for training the factory workers and farmers. The education is the only way to solve the hazard problems caused by the pesticides.

본 연구는 한국사회의 산업화과정에서 배제되어 왔던 전북지역에서 직업집단들간에 생활기회가 얼마나 차등적으로 나타나고 있는지 분석하였다. 좀더 구체적으로 본 연구는 6개 직업범주에 속하는 사람들간에 생활기회의 하위영역인 건강상태와 여가생활 각각이 얼마나 차등적으로 나타나고 있는지 분석하엿다. 분석결과에 의하면, 직업별로 생활기회가 차등적으로 나타나고 있음을 확인할 수 있었다. 즉 직업적 위세가 높은 직업에 종사하는 사람들은 좀더 좋은 생활기회를 가지고 있으며, 역으로 직업적 위세가 낮은 직업에 종사하는 사람들은 열악한 생활기회를 가지고 있다. 먼저 전문-관리직 종사자들은 모든 영역에서 가장 우수한 생활기회를 누리고 있었다. 그 다음으로 전문-기술직, 사무직, 그리고 판매-서비스직 종사자들이 높은 생활기회를 누리고 있다. 그러나 이들 3개 직업집단들 모두가 모든 영역에서 일치된 생활기회를 가진 것은 아니다. 특히 전문-기술직 종사들은 일의 자율성과 안정성에도 불구하고 작업환경의 열악성과 그것이 건강에 미친 영향을 부정적으로 인식하고 있다. 반면에 판매-서비스직 종사자들은 낮은 사회적 인식에도 불구하고 일의 자율성과 높은 수입 등으로 비교적 높은 생활기회를 누리고 있다. 그러나 농업과 생산직 종사자들은 비교적 열악한 생활기회를 가지고 있다. 특히 농업 종사자들은 여가생활부문을 제외한 다른 부문에서 생산직 종사자들보다 상대적으로 좋은 기회를 가지고 있었다. The main purpose of this study is to describe the different life chances among various occupational groups in Chonbuk Province which has been excluded in the process of Korea's industrialization since the 1960s. More specifically, this study analyzed to what extent 6 occupational groups have the different life chances in the sub-levels such as health conditions and leisure life. According to our data analysis, it is found that the 6 occupational groups have the different life chances. That is, while those who are engaged in the higher prestigious occupation have a good life chance, those who in the lower prestigious occupation have a worse life chance. For example, among 6 occupational groups, professional-managerial who secure the higher autonomy and stability in their work have the highest life chance in the labor and health, and leisure life. Next, professional-technical, white-collar, sales-service occupants have the higher life chance after the professional-managerial. However, these 3 occupation groups are partially inconsistent in the two sectors of the life chance. Specifically, the professional-technical, despite their autonomy and stability in the work world, conceived that their work conditions are worse as well as badly influencing on their own health. On the other band, the sales-service workers group, despite their lower social status, is relatively autonomous and stable in their work environment and thus has the higher life chances. Finally, agricultural and productive workers have relatively the lower lift chances. Nevertheless, there are some clear differences among these 2 occupational groups. That is, the farmers have relatively the higher life chances in the sectors of socio-economic characteristics, and labor and health rather than productive workers. As a result, the productive workers are generally located in the lowest level of life chance. This fact is particularly attributed to the fragility of manufacturing industries in Chonbuk Province.

Objectives: The purpose of this study was to seek measures for improvement and management of farm work safety and health by conducting questionnaire surveys and on-site investigations to ascertain the present state of occurrence of safety accidents and safety and health management levels among swine farmers. In particular, the purpose of this study is to provide basic data for the establishment of measures for the management of safety and health suitable to the characteristics of related working environments. Methods: Questionnaire surveys were conducted among 223 farmers engaged in swine farming in 14 regions, and 10 farms were visited in order to implement multilateral methods, including in-depth interviews, along with field surveys. Results: The surveys indicated that 26.2% of all respondents experienced farm-work related safety accidents and body-reaction related accidents showed a high ratio at 31.1% of all respondents. With regard to cause materials of safety accidents, work other than that directly related to swine raising showed high ratios of safety accidents, with pigsty facility related accidents at 26.6%. Although most workers recognized the dangers latent in the working environments, their behavior and responses to the prevention of safety accidents were still insufficient due to a lack of understanding of safety and health management. In the survey on the present state of personal hygiene and wearing of protective equipment, workers were found to have been exposed to dangerous and harmful environments both inside and outside pigsties, but the actual states of their wearing protective safety equipment were very poor. Conclusion: Given the results of this study, swine farmers well recognize problems in their control of safety accidents and management of safety and health, but their knowledge about safety and health education and management guidelines was insufficient. Therefore, safety and health education, public relations, and customized personal protective equipment suitable for swine raising work should be developed in order to address the foregoing problem.
