The quality of service provided by Vessel Traffic Services depends on the tasks characteristics and the work environment of Vessel Traffic Service operators. In this paper, the working conditions of Vessel Traffic Service operators are analyzed in order to propose methods to improve the working environment of Vessel Traffic Services and to provide high quality service through them. The questionnaire survey was conducted for Vessel Traffic Service operators working at 20 Vessel Traffic Service centers. It is expected that it might be used as the basic data for improvement of work environment and organization of Vessel Traffic Service center in the future.

In the various disaster scene effective protective equipment and suppression measures of crisis response cases that is closed all in Korea. Due to asbestos exposure by wearing protective equipment, as well as thoroughly strengthen firefighting, recognize the seriousness of the hazard factors in the fire activity, and established legal system for disease compensation and supplemented by institutional for diseases not yet recognized by officially recognized disaster, fire officials to improve morale and working conditions can be expected to improve major public service.

This study was performed to propose measures to improve and secure safety in the scene activities of firefighters. First, the majority of firefighters thought that working environment and equipment in fire station were inadequate for perforeming work tasks safely. Second, influential factors threatening safe scene activities mainly arose externally such as insecure working conditions of firefighting or emergency scene. Third, improvement in working environments was pointed out as the most urgent issue to secure safety. Firefighters recognized the expansion of field workforce in system, personnel management and the foundation of hospitals for firefighters hospital in working environment, and the development and distribution of safe equipment and change and inspection of air respirator facepiece on regular basis in equipment as urgent issues to be improved.

This paper examines the role of adverse working environments in the determination of workers' compensation in South Korean. I use the Third Korean Working Conditions Survey(2011), Occupational Safety and Health Research Institute that provide relevant variables in objective and subjective compensation and workers of diverse working environment. I find that risk factors in adverse working environments have a very minor role in the determination of individual wages. In contrast, adverse working environments have significant relationship with the level of compensation satisfaction. In addition, the results show that workers are more likely to receive compensation from psychological risk than physical risk. And women receive much more compensation in the psychological risk. These results provide useful information for improvement of working environments.

The nondestructive tests(NDT) are widely applied at various industrial job sites to detect defects and flaws early and thus to diagnose the quality and integrity of components, structures and systems. This paper discusses the R&MD history of various nondestructive testing techniques, their applications and many technical as well as safety issues identified, particularly in the performance of radiography. Also discussed are the principles of inspection methods and NDT qualifications that should be applied at the industrial job sites. As a result, this paper provides suggestions for improvement in Government programs to promote th NDT industry, for more systematic operation through a direct with the owner, and also for improvement in working conditions for NDT workers.

The objective of this study is to survey the working environmental conditions and musculoskeletal workload(DMQ) in red pepper farmers. 155 full-time farmers(males=91, females=64) lived in Chungnam and Jeonbuk participated in the study. To offer the fundamental data for agricultural improvement of red pepper farms, information about working farm conditions, health condition, musculoskeletal disorders(MSDs), labor intensity and musculoskeletal workload was obtained by questionnaire and interviews. The results are as follows: 1. The farmers reported sunlights, high temperature and cold/ draught as uncomfortable work environment. 2. Physical and mental fatigue in females is higher than that of males. 3. The prevalence rates of medical diagnosed diseases are higher in order of osteoarthritis, herniated nucleus pulposus(HNP), and chronic gastritis/gastric ulcer. 4. Prevalence rates of musculoskeletal symptoms more than standard 1 among the various pain areas are higher in order of low back, shoulders and knees. These results can be used practically for agricultural improvement of red pepper farms to prevent MSDs.

The purpose of this study was to evaluate the effect of implementing the HACCP system on foodservice establishments. At first, the hygienic conditions were measured by microbiological hazard analyses of the cooking utensils and working areas. In order to solve the detected problems, the HACCP system was implemented, after what was considered a sufficient settlement period following the initial assessment, then microbiological verification was performed again. In relation to the cooking utensils and equipment(kitchen knives, cutting boards, knives for shredding vegetables, refrigerators, baskets, barts, working tables, preparation tables, tungs, dish-clothes and drains) the microbiological inspection on the Total Plate Count, Coliforms, Staphylococcus aureus and Listeria monocytogenes, were conducted with regard to the working areas(working tables, preparation tables, seasoning's shelves, serving tables, drinking water tables, refrigerators, storage rooms and dining tables), the Total Plate Count and Fungi were also examined. According to the microbiological hazard analyses there were many problems, especially with cutting boards, baskets, barts, dish-clothes and sinkballs. However, by introducing the HACCP system, the microbiological hazard levels were able to be controlled and lowered, and the total aerial bacteria in the working areas of the foodservice establishments were detected at levels below 6 CFU/plate.

For the purpose of investigating the effect of occupational health service in terms of environmental control and health provision of workers on the improvement of worker's health, authors analysed the data of environmental measurement and health check-up of one lead using industry who started his investment to environmental improvement from 1980. Six hundred million won was invested for environmental improvement from 1980 to 1986. This investment brought about apparent improvement of working conditions of all of the workplaces from mean concentration of lead in air over 0.15mg/$m^3$ 1981 to mean concentration of lead in air less than 0.15mg/$m^3$. Environmental control reduced mean blood lead level from 51.2 $\pm$ 11.5ug/이 in 1983 to 39.2 $\pm$ 16.0ug/dl in 1986, and delta-aminolevulinic acid concentration 3.15 $\pm$ 2.1mg/l in 1982 to 1.96 $\pm$ 1. 7mg/l in 1986, respectively. Blood ZPP levels were decreased from 76.1 $\pm$ 58.9ug/dl in 1983 to 42.23 $\pm$ 30.3ug/dl in 1986. If 150ug/dl of blood ZPP is considered as unacceptable limit of lead intoxication, more than 10 percent of workers belonged to this category in 1983, but only 0.5 of workers showed their blood ZPP level over the 150ug/dl in 1986 It was observed that no workers whose work duration were less than one year showed their blood ZPP level over 100ug/dl, but there were high percentages of lead workers with high blood ZPP (over 150 ug/dl) who were working in uncontrolled had working condition and whose work duration were less than one year.

Repetition Strain Injury (RSI) is usually caused or aggravated by poor work processes and unsuitable working conditions - that involve repetitive or forceful movements or the maintenance of constrained or awkward postures. The condition is characterized by discomfort and persistent pain. There are three essential steps to eliminate or control hazards In workplace. Case and Demographic Characteristics for Work-related Injuries and illnesses Involving Days Away From Work, 2002. U.S' was examined. Causes of press operators' RSI were carpal tunnel syndrome(CTS), tendonitis, low back pain, and occupational stress. Recommendations for improvement of productivity are redesign of working conditions, exercise, prevent of RSI and avoiding stress.
