This study was conducted to investigate the labor requirements and transportation cost of paddy for the different harvest and transportation systems for obtaining a basic reference to the improvement of present harvest-transportation systems. One hundred and eighty five farm households with sack type combine harvester and thirty farm households with bulk type combine harvester were surveyed for thirty counties from eight provinces except jeju and also eleven Rice Processing Complex were covered for this survey. This survey was carried from 8th. October 1997 to 5th. November 1997. For the labor requirements, bulk trailer system require 6.8th/ha, 10.3/ha for sack harvest-tractor trailer, and 8.8h/ha for bulk harvest-container bag. The machinery utilization cost for the different paddy harvest-transportation systems, combine sack harvest-tractor trailer system is 282 thousand won/ha, and most economical compared with other systems. Combine bulk harvest with tractor system was 416 thousands won/ha and combine bulk harvest with container bag system was 446 thousands won/ha. In order to propagate bulk harvest-transportation system, a proper bulk transportation means with considering road condition in the paddy field and paddy size should be developed, and considering cycle time it appeared that the proper capacity of bulk container was 3.5ton at the present.

Summarized results of this study that examined the characteristics of farm household in suburban areas classified by the fanning types are as follows. When it was looked into with the side of farm household and his family, the type of the farm household in suburban areas are related to the quality of fanning labor rather than the quantity of it. Regardless of the type of the farm household, it depends upon the family labor (usually men and wives). And the age of farm manager is an important part in the quality of fanning labor. The size of the farm household is related to the individual fanning labor. The size of self-sufficient crops(mainly rice) farm household will be small as the farmer gets to be old. But the size of commercial crops farm household has less tendency to change in terms with the age of farm manager. The fanning commercialism takes an important part in the maintenance and development of suburban agricultural areas. But, in fact, there is a shortage of farming labor. So the physical condition of farmland is the most important part in agricultural durability. After this study, we can conclude that we won't have enough chance to solve the problem of family member separation and shortage of fanning labor even though it is in the suburban area or in the profitable farm until we give them more enough chance to get a job(except fanning) and the better education infrastructure. To make matters worse, the aggravation of farm house-hold's economy due to unstable price of farming products' threatens the agricultural durability. Consequently, in order to get a development of agriculture and rural community, a qualitative change with improvement of agricultural conditions and of products distribution system is needed.

The government separated and established the industrial safety and health law from the Labor Standard law since 1981 to promote the labor's working environment and to improve the conditions of laborers. The government made a lot of effort to discharge the industrial safety and health law by continuous revision of the law thereafter. it is, however, difficult to establish clear-cut lines of authority and responsibility due to the fact that the substantial application of the industrial safety and health law is adapted by enterprise's autonomous management. There are frequent industrial disasters on the small and medium enterprises which have financial difficulty and it means this causes much more social cost. Finally, for the improvement of laborer's safety, health and working environment in the small and medium enterprises we need to raise the effectiveness of the industrial safety and health law through enhancing a government-office's administration and surveillance with the changing mind of a business proprietor. On this paper, we research on the actual condition of the administration, inspection and regulation of safety and health by means of the industrial safety and health law. Thereafter we analyze how much the Korea Occupational Safety & Health Agency and vicarious businesses of safety & health management help. we used the survey method to gather data from 380 laborers directly and analysed the data by SPSS v17.0.

Insomnia is a temporary or continuous condition in which one has difficulty sleeping, due to physical impediments or physical problems. Because insomnia does harms to a labor power or imposes mental and physical burden on a patient, we should pay attention to this disease. This case is about a patient who was 62 years old man with a chronic insomnia since 1996, inspite of no past history about psychical disease. He had sufferred from a cerebral infarction and hypertension since March. 2002. and was hospitalized in Sangji University korean medicine hospital, 25. June. 2002. This patient had been treated by herb-med, Yanggyuksanhwatang for 4 weeks and showed an improvement. This paper describes the process and contents about the patient was cured.

This study was conducted to evaluate work environment monitoring program(WMP) under Industrial Safety and Health Act in Korea. WMP was evaluated by focusing on five key elements, such as purpose, subject, scope, method and workers' participation. The operation status of WMP was evaluated by using questionnaire to workers and data published by Ministry of Labor(MOL). Compliance rate of WMP was less 13 % in manufacturing workplaces. Over-exposure rate was steady state by annual trend. The degree of workers' satisfaction to WMP was just 24 %. A critical problem with the current WMP is that the employer and workers are not acting as main players. For a fundamental improvement in working condition to take place, participation of workers should be expanded and be guaranteed by law.

Recently, both management and labor are interested in the increasing ratio of musculoskeletal disorders. And the developed countries make efforts to consider a counterplan such as prevention activity of musculoskeletal disorders and application possibility of ergonomic program, because musculoskeletal disorders take large portion out of occupational disease. Especially, small and medium enterprises have bigger problems due to the inferior work condition and environment in comparison with big businesses. This study is to introduce developed countries' cases such as WISE(Work Improvement in Small Enterprises) and OSHA Handbook for Small Businesses and to suggest the program of ergonomic management for small and medium enterprises having comparative difficulties against big businesses in improving work environment and managing ergonomic operations.

Large steel water pipes in Korea are joined prevalently by bell end method and welded at inside as well as outside of the pipes with the length of leg which is same as or larger than the thickness of pipes. This results in an excessive consumption of material and labor compared with foreign counturies such as USA, so that in our recent situation of requiring a number of water pipes such consumption is very ineffective and an improvement in weld design of water pipes is urgently necessary. In this experimental study, the possibility of reducing the length of leg to 85% of the pipe thickness was investigated through observations of microstructure and cross section of weldments, the tensile test, and the impact test of the field and laboratory specimens. As the results of this study, it was revealed that water pipes which have the leg of fillet about 0.8xthickness show a good weldability, have a greater strength than the base metal and absorb the enough energy to be safe in the working condition of the pipes.
