This study was conducted to evaluate the effects of lead on the incidence of anemia and to find cases with lead poisoning early among female workers who have been exposed to lead occupationally, for one year from August, 1985. The level of blood lead and hemoglobin concentration were observed for 284 female lead workers and 123 female non-lead workers of industries in the Gumi industrial complex in Kyungpook Province. The average age was $20.3{\pm}2.9$years and $21.1{\pm}3.5$ years in lead workers and non-lead workers, respectively. The average working duration was $26.46{\pm}19.26$ months in lead workers. The mean value of blood lead was $30.11{\pm}6.61{\mu}g/100ml$ and $21.86{\pm}3.75{\mu}g/100ml$ in lead workers and non-lead workers, respectively. There were significant differences between two groups. The mean value of hemoglobin concentration was $14.00{\pm}0.57g/100ml$ and $14.03{\pm}0.64g/100ml$ in lead workers and non-lead workers, respectively. Anemia cases were not observed at Hb concentration below 12g/100ml. The percentages of lead workers at Hb concentration ranged 12.0~13.0g/100ml were 4.5%. There was no dose-response relationship between blood lead level and the incidence of anemia. There were no remarkable differences between age and blood lead level as well as Hb concentration, and between working duration and the level of blood lead and hemoglobin.

In order to understand distribution characteristics and pollution of heavy metals in the artificial Lake Shihwa in the vicinity of Kyunggi Bay in relation with huge environmental changes, various environmental samples including seawaters, surface sediments and settling particulate matters were collected from Lake Shihwa in 2004. Due to extreme pollutant discharge from various anthropogenic sources such as the Banweol and Shihwa Industrial Complexes and cities, the highest metal concentrations in the samples such as waters, sediments and settling particulate matter were found in inner part of the lake. High metal contents (Cu, Zn and Hg) in sediments were observed at Sts. 2-4 and 9. The contents of Cr, Co, Ni, Cu, Zn and Pb in SPMs were high at St. 5 and low in the outer part of the lake. Spatial distribution of heavy metals were mainly controlled various biogeochemical factors and physical mixing as well as input of industrial and municipal wastewaters. Although tile environmental qualities of heavy metals in the lake have been improved partially due to inflow of outer seawater, it is not clear to reach a good environmental quality. Therefore, further environmental programs should be conducted continuously for environmental improvement.

The primary goal of this study was to investigate factors affecting job satisfaction of injured workers who returned to work. There are two types of injured workers' returning to work returning to pre-injury job and getting a new job. After separating the two types of workers we conducted the multiple regression analysis on the data from the Workers'Compensation Insurance Panel of the Korea Workers' Compensation and Welfare Service Corporation(2014). The sample consisted of 1,333 occupationally injured workers who were finished with medical treatment(693 workers returned to previous work place, and 640 workers found new work places). Main results are as follows. First, injured workers who got new jobs were vulnerable to sustainability to job, work status, average monthly wage as well as job satisfaction compared with injured workers who returned to pre-injury job. Second, gender, educational level, skill fitness, average monthly wage, welfare benefits, family income/leisure life/residential environment/social relation satisfaction, and maintenance of relation with business owner during medical care were related to job satisfaction of injured workers who returned to pre-injury job. Third, gender, work status, skill fitness, continuous work possibility, average monthly wage, family income/leisure life/social relation satisfaction, substitute worker for assigned task during medical care and maintenance of relation with business owner during medical care affected on job satisfaction of injured workers who got new jobs. Based on these findings implications for policy and interventions were discussed in regards to job satisfaction of injured workers.

A significant rise in product-liability cost is expected due to the newly passed product liability amendment Bill approved during the assembly plenary session on March 30, 2017. Korean government legal service(KGLS) filed a damage suit against Korea aerospace industries, Ltd.(KAI) and Hanwha Techwin Co., Ltd., the manufactures of the KUH-1 Surion helicopter crashed. KGLS alleged claims under the product liability Act, the warrant liability Act and the non-performance of contract act. The accountability limits of military aircraft manufacturers was a highly divisive issue among related scholars and legal practitioners. The bottom line was that military aircraft manufacturers had no product-liability insurance available. The United States courts have, therefore, developed the government contractor defense(GCD) and it was recognized by the U.S. Supreme Court in Boyle v. United Technologies corporation(1988). product liability insurances for military aircraft manufacturers are excessively expensive and it cannot be added onto the military procurement cost accounting. However, having an aircraft accident without one can be ruinously expensive. Therefore, the manufacturers should promptly set up appropriate risk management measures. This thesis will first review the advance GCD theory, and then find a way to either reform government contract related regulations.

In recent years, the number of high-rise building construction projects has grown, and the number of construction safety accidents has also been increasing. Therefore, the objective of this study is to propose plans to prevent accidents by systematically organizing accident principles and developing a tree diagram for the process of safety accidents that occur in the construction industry. This study aims to show the diverse characteristics of construction accidents based on KOSHA's annual reports on safety accidents(burial, conflagration, explosion, burn) from 1993 to 2009. To achieve these objectives, in this study we first examined the risk factors for burial, conflagration, explosion, and burn. We then systematically organized the classification viewpoint of accident causes, and suggested a methodology for the rationalization of safety management through an analysis of the primary causes of accidents by work type. The results of this study based on this methodology can be divided into three areas: 1)the types of facilities were divided into 43 categories by analyzing the information of KOSHA's annual reports; 2)the causes of burial, conflagration, explosion, and burn were divided into 63types; 3)the types of work were divided into 29 categories.

This study analyzed the location of manufacturing industries and works' residence in Yangsan city of which large part of industries were relocated from Busan metropolitan area along the industrial suburbanization process. Through the field survey, in-depth interview, and analysis of statistical data, the study tried to describe the relocation characteristics of manufacturing industries in Yangsan city. The results of the analysis are as follows: 1. The relocation rate of manufacturing industries from Busan to Yangsan was very high in 1980s. As a result of analysis, the first prime factor on relocation was the site problem for industrial land use. But for the newly starting industries, the most important factor was the subcontract networks among industries which differed from relocated ones. 2. The industrial suburbanization process influenced on the industrial structure strongly, as the compositional weight of rubber and plastic industries in Yangsan became greater and the size of the major plants got larger. 3. The manufacturing industries in Yangsan city were widely distributed on the main national industrial districts. Also, they were diffused out to the other places beyond the boundary of industrial districts. 4. The commuting workers' residence in Busan, employed by the plants of Yangsan marked 44.5%. That confirmed the strong influence of Busan labor market.

Chemical plant's fire and explosion does not only damage to the chemical plants themselves but also damage to people in or near of the accident spot and the neighborhood of chemical plant. For that reason, Chemical process safety management has become important. One of safety management methods is called 'the quantitative analysis', which is used to reduce and prevent the accident. The results of the quantitative analysis could be used to arrange the equipments, evaluate the minimum safety distance, prepare the safety equipments. In this study we make the computer program to make easy to do Quantitative analysis of the accident. The output of the computer program is the magnitude of fire(pool fire and fireball) and explosion(UVCE and BLEVE) effects. We used the thermal radiation as a measure of fire magnitude and used the overpressure as a measure of explosion magnitude. In case of BLEVE, the fly distance of fragment can be evaluated. Also probit analysis was done in every case. As the case study, Buchun LPG explosion accident in Korea was analysed by the program developed. The simulation results showed that the permissible distance was 800m and probit analysis showed that 1st degree bum, 2nd degree burn, and death distances are 450, 280, 260m, respectively the simulation results showed the good agreement with the results from SAFER PROGRAM made by Dupont.

The purpose of this study was to investigate the scientific basic grounds for the assessment of health and environmental diseases resulting from air pollutants in Pohang. For this study, we investigated pollutants, weather characteristics and concentration distribution of fine particles ($PM_10$) yearly and each season, using data from Air Quality Monitoring Stations. The properties of concentration distribution and seasonal fluctuation of $PM_10$ were studied qualitatively and quantitatively using CALPUFF, air dispersion model. The average concentration of $PM_10$ for each season was spring($75.7{\mu}g/m^3$)>summer($56.8{\mu}g/m^3$)>winter($53.6{\mu}g/m^3$)>fall( $52.7{\mu}g/m^3$). In the case of spring, high concentrations appear due to the Asian dust frequently occurring. The contributions of $PM_10$ classified by the types of pollution source in Pohang were point source 62%>mobile source 33%>area source 5%. An important point is that 97% of emissions were produced from the iron manufacture in steel industry. Therefore, it is necessary to control the emission sources of pollutants and to construct an observation system at Pohang steel industrial complex from now on. It’s time to control the risk factors for health and environmental disease to protect the health of resident in Pohang and its neighboring areas.
