Investigation of the odor source is necessary to establish of the effective counter plan for reducing the odor emitted from the industrial complexes. This study was carried out to investigate the characteristics of the odor emitted from leather manufacturing plants, using three methods which are a direct sensory technique, an air dilution sensory test and a instrumental analysis. Total 7 samples were sampled at 3 points of three factories in this study. As a results of this study, while odor intensity of 7 samples ranges from 2 degree to 4 degree, dilution ration of olfactory test shows the range from 300 to 600. It was estimated that main malodorous compounds ordered hydrogen sulfide, methyl mercaptan, i-valeraldehyde.
In this study was analyzed substances that high contribute to odor strength degree which emitted from the painting, the plating, the casting, the rubber manufacturing, and the used oil refining facilities in Gwangju Hanam industrial complex. In order to this, we analyzed two types of nitrogen compounds, five types of sulfur compounds, thirteen types of the aldehyde, and ten types of volatile organic compounds discharged from an outlet for antipollution facilities. The results are as following high contribution rate sustances to odor strenth was ordered butylaldehyde (73.8%) > acetaldehyde (17.7%) > propionaldehyde (4.9%) at painting facilities. At plating facilities, it was ordered Acetaldehyde (59.0%) > ammonia (19.1) > hydrogen sulfide (13.1%). At casting facilities, it was ordered Hydrogen sulfide (65.9%) > acetaldehyde (17.2%) > sulfur dioxide(5.2%). At rubber manufacturing facilities, it was ordered i-valeraldehyde (35.0%) > butylaldehyde (32.0%) > n-valeraldehyde (13.3%) and at used oil refinery facilities, it was ordered Acetaldehyde (36.8%)> butylaldehyde (33.6%) > sulfur dioxide (14.5%).
There are two kind of method to perform a safety management in industrial field. One is a management by safety manager employed in company and another one is safety management by acting agency. In case of the company that managed by the acting agency dose not coincide with the state of company and safety management performance because of the safety management is carry out by periodically. Therefore it is considered that the sufficient safety management is difficult. And a company that employ a safety manager also show a low level of safety management compare with the advanced country in view of safety and health. From the statistics of accident rate of the company, it is necessary that an improved safety management through the studying and analysing a coverall matters for the company that managed by acting company.
Currently, in Korea, an accident that takes place during a worker's commuting is generally not considered as work-related accident. However, there are several exceptions such as an accident that occurs in commuting while using transportation provided by an employer, an accident that happens during commuting time that can be regarded as part of a business activity (e.g. tending to work instructed by an employer on the way to or from work), and an accident that is caused by insufficient facility management by an employer. It is even more so as the workers' commuting distance increases with expanding scale of a city, and traffic accident occurs more frequent. Social risk of commuting-time accident is on the rise. Under this circumstance, it is an important social issue to explore how to protect workers from commuting-time accident.
A major purpose of management or occupational safety is a significant decrease in safety accidents. With this view, the establishment of occupational safety culture and the building of occupational communication network stand out as being more important than the past. This study has analysed the positive effects of occupational safety communication on safety consciousness and action of the employees in workplace. And it is confirmed that the occupational safety communication in workplace is the essential mechanism, through which the workers internalize safety consciousness and act safely. The safety consciousness and action of the employees are formed in safety culture, which is not only legal regulations, but a daily communication network in workplace. In these sense, the building of the occupational safety communication network is decisive for the establishment of safety culture. For these reasons, this study makes the proposition that a firm promotion of occupational communication network is necessary, which connects the safety culture and a effective safety management in workplace.
In this study, we used an electronic nose to measure odor intensity and odor quality against an absolute scale. The major feature of this device is that it automatically corrects for differences in sensor sensitivity and smell sensitivity due to odor quality, which allows the intensity of any odor quality to be determined at olfactory sensitivity. In addition to determining the odor intensity as an odor index value, in the standard mode, the device can determine the odor quality by separating and displaying the overall odor on nine category axes (sulfur, amines, organic acids, aldehydes, aromatics, esters, hydrocarbons, hydrogen sulfide and ammonia). This device achieves these results by subjecting the signals from the ten oxide-semiconductor odor-sensor elements to our unique absolute value representation analysis. This study applied electronic nose system of sensor type that can evaluate odor characteristics by real time in leather industry spot and investigated problem that can happen odor sensory method and instrumental analysis method. Also, by evaluation correlation between each measurement method, groped efficient odor evaluation method, and evaluated the effectiveness, Usually, because measurement surrounding and consistency according to measurer"s state of olfactory method are apt to be been lacking, error range is large. If take into account these problem, odor sensor"s result that examine in this research is judged that there is inter-relationship enough with olfactory method result. In comparison between odor sensory test result and instrument analysis result, odor characteristics estimation that can bring synergy effect more than equality in box judge.
In the steel industry, steel is manufactured and processed to produce a variety of steel products. The industry provides fundamental materials to the whole range of industries including car, ship, electric appliance and construction industries, so that it is very important as an infrastructure industry. The steel manufacture process involves aerial work, many danger factors caused by the treatment with hazardous gases including BFG and COG and by high pressure gases including H2, O2, N2 and LPG. It requires the management over the large area because many workers work in a plant. The potential dangers in the steel plant were identified and the effect of the danger assessment was verified through the analysis of the danger assessment for the steel plant. The allowed degree of danger was lowered after the improvement through the danger assessment in the plant where the case studies were conducted, which indicates that the danger assessment is highly effective.
Steel and iron works have place many hazard or risk factor as a high temperature material, a high place, and so on. Accordingly, steel and iron works need system for risk assessment. In this paper, we development of risk assessment system for steel and iron works. In case study applied at the steel enterprise. The resultant, we can discovery that an human factor is an important question form risk assessment.

The present management of the domestic and international advanced enterprises is transferring the systems and the regulations to the prevention system management. Expecially, KOSHA (Korea Occupational Safety & Health Agency) in Korea has supported to set up the OSHMS (Occupational Safety & Health Management System) by KOSHA 18001 since 1997. But small & medium enterprises (SMS) has many difficulties to set up the OSHMS system because of limited natural and human resources. In this study, the rating system as a judgment method of an OSHMS based on the certification standard of the OSHMS, which was suggested in previous study, was developed for SMS to adopt voluntarily the OSHMS, certify KOSHA 18001, and improve the safety and health level.

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.
