This study was designed to devise work wear for plastic house worker. It was carried out (1) research on the clothing actual condition through interviewings with plastic house worker and observations, (2) thermal manikin test to measure thermal resistance of experimental clothes and (3) clothing comparing test in the laboratory and in the plastic house. In the laboratory experiment, it was choosen general type (A) and new devised types (B, C) made of microporous fabric for experimental clothes. Experimental clothes were made of 6 combinations including 3 type work wears (A, B, C) and 2 type underwears (1, 2). In the plastic house experiment, it was choosen general types of A (without rest place) and B (with rest place), and devised type C (with rest place), which was appeared good effect in the laboratory experiment. The results were as followings. 1. Work environment of the plastic house in summer and winter was very different from the outer environment. Work motion in the plastic house was burden to the plastic house workers. 2. Plastic house workers had on the general type's work wear. 3. As a result of thermal manikin test, thermal resistance was appeared B1>B2>C2>C1>A1>A2 in orders. 4. In the laboratory experiment, experimental clothes A was appeared smaller burden than B, C. Effect of mesh underwear was not appeared in this study condition. In subjective sensation, experimental clothes C was lower vote than A. Therefore experimental clothes C was superior to A in subjective wearing sensation. 5. In the plastic house experiment, the experimental conditions with rest place were appeared smaller burden than without rest place. General type B was appeared more positive physiological reactions than devised type C but significances between two types was not appeared.

Korea has different agricultural pattern from western countries and in particular, pesticide application has been performed by individual farmer. Such situations can result in pesticide exposure to worker at significant level. Thiophanate-methyl is a benzimidazole fungicide, which has been used for the wide range of fungal pathogens in field crops and fruits in Korea. It is insoluble In water, and is stable in neutral, aqueous solution at room temperature. It is a carbendazim precursor and systemic fungicide with protective and curative action. Toxicity to mammalian is low as ADI value is 0.08mg/kg b.w. (Tomlin 2000).

In this study we tried to examine the efficiency of the agricultural convenient tool (put-on-style-stool) by observing subjects'physiological responses. For this we measured subjects' heart rate, oxygen consumption, blood lactate level, mean skin temperature and rectal temperature. The results of this study are as follows; Heart rate was 75$\pm$2 beats/min with the put-on-style-stool and 78$\pm$2 beats/min without it (P＜0.01). Oxygen consumption was 3.88$\pm$1.90 $m\ell$/kg/min with the Put-on-style-stool and 5. 06$\pm$0.40 $m\ell$/kg/min without it (P＜0.05). Blood lactate level was 2.39$\pm$0.64 mmol with the put-on-style-stool and 3.38$\pm$0.45 mmol without it (P＜0.05). Mean skin temperature was lower but rectal temperature was higher with than without the put- on - style - stool (P＜0.05 and P＜0.01 respectively) So, using the put-on-style-stool was evaluated positively in farmer's work.

The purpose of this study is to survey job stress and Musculoskeletal Disorder(MSDs) of workers in small plants with agricultural products. The subjects were comprised of 69 workers participated in "Helping the rural women to get the small businesses" project. The questionnaire surveys were Korean Occupational Stress Scale(KOSS), and Legal Risk Assessment of Musculoskeletal Disorders(KOSHA CODE H-30-2003). As a result of the survey, scores of KOSS 8 sub-items except for job demand were similar to that of Korea workers. Prevalence of MSDs symptoms of small plants workers was high percent (44.9%). And the rate according to kinds of product was significant difference at neck (p<0.01), lumbar (p<0.01), and leg (p<0.01). There was no significant difference between view person sign of MSDs and non MSDs according to sex, year, the number of workers, working years, working time per one day, rest time per one day, and subjective working intensity, but there were significant difference between high stress group and low stress group about MSDs at interpersonal conflict(p<0.05). Job stress and MSDs were important factor to workers of small plants producted agricultural products. Therefore, starting a business with small plats, workers consider interpersonal conflict and body part showing MSDs.

Cooling air-conditioning of APC (Agricultural Products processing Center) workplace is important to improve the working environment in the summer season. As existing cooling systems for air-conditioning of whole workplace are inefficient because of their high equipment operating costs, relatively inexpensive cooling system is required. The objectives of this study were to simulate the thermal flow fields in APC workplace having the positive and negative pressure type fan and pad systems and spot cooling system by using CFD software (FLUENT, 6.2) and estimate the cooling effectiveness of respective cooling systems. The results showed that the negative pressure type fan and pad system was inappropriate for the present APC workplace because of excessive outside air influx from open gateway and the positive pressure type fan and pad system created relatively low temperature field but non-uniform velocity field at worker positions. The spot cooling system could supply cool air to worker positions with relatively constant air velocity and temperature.

We investigated oviposition and colony development of Bombus ignitus and B. terrestris depending on different pollen. In five kinds of pollen blend, the colony development in fresh-freezing pollen blend produced in Korea (Korea-FFP) was the best performance, although egg-laying characteristics is lower than that of pollen blend for oviposition imported from Korppert company (Kopport-FOP). The Kopport-FOP proved that it was suitable to use for oviposition of bumblebees. The Korea-FFDP, freezing dried-fresh pollen blend produced in Korea, is lower rather than the Korea-FDP although it is similar to the KopportFOP in colony development. It is not efficient to use commercial pollen for bumblebee because it is expensive in cost. The dried pollen blend for honeybee feeding imported from China (China-DP) was not suitable for rearing of bumblebee because it did not form colony although the worker emerged. In types of pollen, the oviposition and colony development of B. ignitus were not affected by the fresh-freezing pollen and dried-freezing pollen. This result also indicated that dried pollen, dried in the shade for 5 - 6 days, is possible to use as commercial pollen for bumblebee reproduction.

A high prevalence of farmer's work-related musculo-skeletal disorders (MSDs) have been reported in precedent studies. Risk factors - physical, chemical, biological, ergonomic risk factor etc. - in farm-work were identified by previous studies. To prevent farmers from exposing to them and reduce, Agricultural Safety Technology were introduced and used on farm. The purpose of this study is to review and summarize the agricultural safety technology on farm in Korea. According to strategy principles, this technology is classified as four criteria - workload reduction by reducing awkward posture, workload reduction by using manual material handling aids, Comfort improvement by protecting worker from hot, cold environment and work efficiency improvement by workplace redesign and cultivation modification. This technology includes transporting tools, working cloth, personal protective equipment, and pesticide-proof Clothing. Anthropometric study of Korean farmers was also carried out to support the development of equipment and clothes. In long terms, it needs to precaution activity from risk factors by using cultivation modification and working improvement. Although working condition gets better and workload reduce by this technology, it required customized safety technology in each crops - rice cultivation, horticulture and livestock farming. And farmers should use the assistive technology and participate voluntarily in ergonomic intervention program.

This study was carried to devise comprehensive policies for systematically fostering the eligible farmers in Korea based on their vocational developing stages such as potential stage in juvenile days, preparing stage in agricultural schools and colleges, farm worker stage under farm manager, ownership farming stage and professional farm manager stage. Of course all of these developing stages are not necessary but desirable processing to be a good farmer. At least more than two stages are necessary to be a professional farm manager. In order to systematically foster the eligible farmers as many as demanded in Korea, appropriate policies in the every stage should be devised. As the result of this study, several programs were sugested as the appropriate policies such as development of school 4-H program in potential stage, scholarship program in preparing stage, supporting programs for the farmhouse-hold having a family's farm management agreement, development of the instalment savings program for the young farm workers and farmer's certificate program, etc.

Objectives: By conducting a meta-analysis of cohort studies reporting standardized mortality ratios (SMRs) for workers exposed to trichloroethylene, we attempted to adjust for healthy hired effect by applying the same methods as described in a recent report from the Agricultural Health Study. Methods: Among all cohort studies that evaluated the association between all cancer, non-Hodgkin's lymphoma (NHL), kidney cancer, liver cancer and occupational exposure to trichloroethylene, a total of 10 studies reporting SMR values were selected. A random-effects model was used to estimate the summary SMRs or rSMRs and 95% confidence intervals. Relative SMR ($rSMR=SMR_x/SMR_{not\;x}$) was calculated comparing observed and expected counts for all cancer, NHL, kidney cancer, and liver cancer with an independent referent set of values consisting of the observed and expected counts for other causes. Results: The SMR values for all causes ranged from 0.68 to 1.03, suggesting moderate to weak healthy worker effect for the selected studies. When the healthy worker hire effect was taken into account, the summarized risk became statistically significant; the summary SMR of all cancer was 0.95 (0.91-1.00) and the summary rSMR of all cancer was 1.10 (1.04-1.15). The summary SMR of NHL was 1.04 (0.93-1.14) and the summary rSMR of NHL was 1.23 (1.04-1.46). The summary SMR of kidney cancer was 1.08 (0.88-1.33) and the summary rSMR of kidney cancer was 1.23 (1.02-1.49). The summary SMR of liver cancer was 0.88 (0.78-0.99), and the summary rSMR of liver cancer was 0.95 (0.84-1.07). Conclusion: The rSMR method is useful to determine summary risk adjusted for healthy worker effect through meta-analysis.

The fact that cooperation is an essential factor for foodservice industry success has been discovered by many business leaders. Success in entrepreneurial businesses depends upon cooperation. However, there has been a lack of studies done about cooperation in the service industry, particularly levels of cooperation among foodservice employees in an organization. This study is designed to understand the antecedents, servant leadership and trust in co-workers that have a resulting influence on cooperation among foodservice employees. To achieve the study objective, 191 valid questionnaires were statistically analyzed, using frequency analysis, factor, reliability analysis and multiple regression analysis. The following is a summary of my verified analysis. First, servant leadership have a positive influence on trust in co-workers. Second, trust in co-workers has a positive influence on cooperation among foodservice employees positively.
