Recycling is a main issue in protection of the environment and waste collection and sorting have much higher value in current recycling policies than they did previously. Waste collectors, like firefighters and policemen, are working for the public benefit, however, waste collection is more dangerous than either police or firefighting work. In the USA, waste collectors are 10 times more likely than the average worker to die on the job. Waste collectors also suffer from musculoskeletal disorders, infectious diseases and various injuries. If we truly appreciate the worth of waste collectors, we need to improve their working environment and personal hygiene. Furthermore, abolishing discrimination will be a very important step towards greater protection for waste collectors.

The purpose of this study is to provide empirical basic data to develop public uniforms design, by understanding international universality and advanced design sense, through the analysis of public uniforms design at home and abroad. The theoretical study reviewed the character and area of public design, and the concepts and requirements of public uniforms. The empirical study analyzed public uniform design at home and abroad, focusing on typical public uniforms, such as police, fire fighter, and street cleaner. The results of this study were as follows. First, the police uniform has a standardized and formal suit style, which consists of a single-breasted dk-PB jacket with a notched collar and pants. It uses PB as the main color, to show their authority and role reliability. Epaulet or badge, which represents belonging and difference in rank, are attached to express the identity of an organization. Second, the fire fighter uniform consists of a hip length coat with a stand collar effective for heat shielding, and straight pants with flap pockets, in which it is easy to put things. Its main color is dkg-PB, to mitigate visual fatigue and enhance comfort, and an accent color scheme is used, to effectively raise visual attention and safety. Finally, the street cleaner uniform has a casual style, which consists of a jumper with a shirt collar and pants for high activity. v-YR and R with high chroma is mainly used, for increased attention during day and night work, to stress safety.

The purpose of this study is to assess respirable crystalline silica (RCS) exposure levels in workers who collect and dispose used coal briquette ash (CBA) in sanitation companies that are subcontracted by one medium-sized local government on the collection of municipal household waste (MHW), and to analyze the quartz content in CBA. When the CBA powder that undergone specialized pretreatment in several steps were subjected to mineral identification and quantitative analysis using X-ray diffraction (XRD), it was found that quartz represented 18%, and in addition, mullite, and plagioclase were included. For two CBA collectors, samples were collected by the personal sampling evaluation method. After respirable dust was collected in accordance with the National Institute for Occupational Safety and Health 7500 method, the concentration of quartz was analyzed using XRD. Meanwhile, a portable real-time dust monitor (Sidepak AM520, TSI Inc., USA) was also used to observe the dust exposure level for each time zone and job task. The RCS exposure level of one worker was as high as 0.024 mg/㎥, which was the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values (TLV) level. The other worker also exhibited a concentration of 0.013 mg/㎥, which was more than half of TLV. The Sidepak results revealed that the work of collecting CBA and loading it onto a vehicle was hardly exposed to the dust of a significant level. It was found, however, that the work of transferring the collected CBA to a container through a conveyor belt was exposed to a very high average respirable dust concentration of 2.238 mg/㎥. The results of this study confirmed that quartz, which is crystalline silica and a carcinogen, is contained in CBA, one of municipal household waste (MHW), in high concentration. It was also confirmed that workers are exposed to high RCS concentrations while transferring collected CBA into a container. Although each local government in South Korea handles CBA in different ways, it is imperative to investigate the CBA exposure level of sanitation workers and improve their working conditions.

Thereby. the results of this study were to provide useful data as a contribution to knowledge for health protection and promotion. The data used for this study were environmental workers' physical examination cards; the male environmental workers were 52 persons. and the female environmental workers 52 persons. The data were analyzed by descriptive statistics, t-test, Pearson correlation, and distinction analysis, using the SPSS program. The results of this study can be summarized as follows; 1. Thers was a significant statistical difference between the two groups as to height. eyesight. serum GPT, hematocrit. The variables having little difference between two groups were weight. systolic blood pressure. total cholesterol. creatinine. 2. The rate of revealed in significant health examination was extra-health discrimination rate $28.8\%$, significant result of illness rate $12.5\%$. injury-inflicting rate $7\%$. second-time urine test $5.7\%$. antigen positive 3.8%. hearing impairment $2.8\%$, urine protein positive $1.9\%$. and urine sugar positive $1.9%$. 3. The workers diagnosed as extra-health discrimination were 30 persons or $28.8\%$. There was a difference between two groups on the prevalence. In the male environmental workers. ten times live problems and six times pulmonary tuberculosis and three times circulatory problems were revealed the higher than thoes of the female environmental workers. 4. In the male environmental workers, the relationship between age and systolic blood pressure revealed a significant correlation (r=0.22. p<0.05). In the female environmental workers. there was a negative correlation between age and weight (r= 0.25, p<0.05). the relationship between age and total cholesterol correlated positively (r=0.30, p<'0.05). 5. In the male environmental workers, there was a negative correlation between working career and creatinine(r=-0. 22, p<0.05) In the female environmental workers, there was a positive correlation between working career and total cholesterol (r= 0.58, p<0.01). 6. There were significant differences on working career and creatinine accdording to the male and female environmental workers who had any problems through x-ray inspection. 7. There were significant differences on height. eyesight. serum GPT according to the male and female environmental workers who were diagnosed as extra-health discrimination. 8. The female environmental workers who were diagnosed as 'care' were positively correlated with weight (r= 0.26. p<0.05)' and systolic blood pressure (r= 0.30. p<0. 05). on the other hand. the left and right eyesight correlated nagatively(r=-0.15. r=-0.33. p<0.01). 9. The most influential variables on the male and female environmental workers' health condition were working career, height. and weight. And these three variables could help determine the two groups at the level of 81. 8 percentage.

의료기관 핵의학과에서는 진단과 치료를 목적으로 방사성동위원소를 사용하므로 누구나 방사선피폭에 노출 될 위험이 있다. 일반적으로 방사선 작업종사자에 대한 피폭관리는 비교적 철저히 이루어지고 있으나 환자보호자 및 일반인에 대한 피폭관리는 소홀한 경향이 있다. 특히 방사성의약품을 투여한 환자들은 잠재적 선원이 되어 작업종사자외에 환자보호자 및 일반인에 대해 방사선피폭을 초래하므로 이로 인한 방사선피폭을 최소한으로 감소시킬 수 있도록 관리되어야 한다. 따라서 핵의학과 방사선피폭에 대한 관리실태를 파악하기 위하여 전국에 있는 대학병원 중 7개소에 대해 조사한 결과 환자이송요원, 환경미화원 등 수시출입자에 대해서 2 개소의 의료기관에서는 피폭선량평가 및 관리와 안전교육이 없었다. 또한 환자와 동행하는 보호자에 대한 통제와 관리는 7 개소 모두 허술하였는데 대기실에서 검사직전 환자로부터 흡수될 수 있는 평균 방사선량률은 25.60 ${\mu}$Sv/h로서 일반인에 대해 연간 선량한도를 초과하지 아니하는 범위 내에서 허용되는 20 ${\mu}$Sv/h를 초과하였다. 따라서 비록 아주 적은 피폭선량이 예상된다고 하더라도 수시출입자에 대한 철저한 피폭선량의 관리와 교육이 요구되며, 환자보호자 등을 보호하기 위해 환자와 가까이 하는 것을 통제하거나 환자를 격리할 필요가 있었다.
