Recently, the CO2 emission and energy consumption have become critical global issues to decide the future of nations. Especially, the spread of IT products and the increased use of internet and web applications result in the energy consumption and CO2 emission of IT industry though information technologies drive global economic growth. EU, the United States, Japan and other developed countries are using IT related environmental regulations such as WEEE(Waste Electrical and Electronic Equipment), RoHS(Restriction of the use of Certain Hazardous Substance), REACH(Registration, Evaluation, Authorization and Restriction of CHemicals) and EuP(Energy using Product), and have established systematic green business/IT strategies to enhance the competitiveness of IT industry. For example, the Japan government proposed the "Green IT initiative" for being compatible with economic growth and environmental protection. Not only energy saving technologies but energy saving systems have been developed for accomplishing sustainable development. Korea's CO2 emission and energy consumption continuously have grown at comparatively high rates. They are related to its industrial structure depending on high energy-consuming industries such as iron and steel Industry, automotive industry, shipbuilding industry, semiconductor industry, and so on. In particular, export proportion of IT manufacturing is quite high in Korea. For example, the global market share of the semiconductor such as DRAM was about 80% in 2008. Accordingly, Korea needs to establish a systematic strategy to respond to the global environmental regulations and to maintain competitiveness in the IT industry. However, green competitiveness of Korea ranked 11th among 15 major countries and R&D budget for green technology is not large enough to develop energy-saving technologies for infrastructure and value chain of low-carbon society though that grows at high rates. Moreover, there are no concrete action plans in Korea. This research aims to deduce the priorities of the Korean green business/IT strategies to use multi attribute weighted average method. We selected a panel of 19 experts who work at the green business related firms such as HP, IBM, Fujitsu and so on, and selected six assessment indices such as the urgency of the technology development, the technology gap between Korea and the developed countries, the effect of import substitution, the spillover effect of technology, the market growth, and the export potential of the package or stand-alone products by existing literature review. We submitted questionnaires at approximately weekly intervals to them for priorities of the green business/IT strategies. The strategies broadly classify as follows. The first strategy which consists of the green business/IT policy and standardization, process and performance management and IT industry and legislative alignment relates to government's role in the green economy. The second strategy relates to IT to support environment sustainability such as the travel and ways of working management, printer output and recycling, intelligent building, printer rationalization and collaboration and connectivity. The last strategy relates to green IT systems, services and usage such as the data center consolidation and energy management, hardware recycle decommission, server and storage virtualization, device power management, and service supplier management. All the questionnaires were assessed via a five-point Likert scale ranging from "very little" to "very large." Our findings show that the IT to support environment sustainability is prior to the other strategies. In detail, the green business /IT policy and standardization is the most important in the government's role. The strategies of intelligent building and the travel and ways of working management are prior to the others for supporting environment sustainability. Finally, the strategies for the data center consolidation and energy management and server and storage virtualization have the huge influence for green IT systems, services and usage This research results the following implications. The amount of energy consumption and CO2 emissions of IT equipment including electrical business equipment will need to be clearly indicated in order to manage the effect of green business/IT strategy. And it is necessary to develop tools that measure the performance of green business/IT by each step. Additionally, intelligent building could grow up in energy-saving, growth of low carbon and related industries together. It is necessary to expand the affect of virtualization though adjusting and controlling the relationship between the management teams.

Objectives: A great number of hazardous agents can be emitted from various types of art-creation in a fine arts college, but little data on exposure assessment has been published. A variety of processes encompassing toxic or non-toxic materials, tools, and components are involved in a sculptor work at a fine art college. The aim of this study was to assess exposure levels to particulates and noise during sculpture classes in a college of fine arts. Methods: Students in sculpture classes participated in this study. Mass, number, and surface area concentrations of particulates, noise level, temperature and relative humidity were monitored by both personal and area sampling during the tasks of metal, wood, and stone sculpting. Results: The number and surface concentration of particulates was the highest in the task of wood sculpting, followed by metal and stone work. The mass concentration of particulates was the highest in stone sculpting (personal GM 3.0 mg/$m^3$, GSD 3.0), followed by wood (personal GM 1.5 mg/$m^3$, GSD 1.8) and metal work (personal GM 0.95 mg/$m^3$, GSD 1.51) in that order. Occupational exposure limits (OEL) for particulates depends on the type of particulate. For wood dust, 86% (six subjects) of the personal samples and all area samples exceeded the Korean OEL for wood dust (1 mg/$m^3$), while 20% (two subjects) among stone sculpting students were exposed above the Korean OEL (10 mg/$m^3$). In contrast, metal sculpting did not exceed the OEL (5 mg/$m^3$). For noise level, metal sculpting students (Leq 95.1 dB(A) in the morning, 85.3 dB(A) in the afternoon) were exposed the most, followed by stone sculpting (88.3 dB(A)), and wood sculpting (84.8 dB(A)) in that order. Compared with the 90 dB(A) of the Korean OEL and 85 dB(A) of the American Conference of Governmental Industrial Hygienists' threshold limit value (ACGIH-TLV) for noise, 100% of the subjects (five subjects) and area samples during metal sculpting in the morning session exceeded both OELs, but only three subjects (60%) exceeded the ACGIH-TLV in the afternoon session. For stone sculpting, 50% (one subject) and 100% (two subjects) exceeded the Korean OEL and ACGIH-TLV, respectively, but the area sample did not exceed either OEL. During wood sculpting, two subjects (40%) exceeded ACGIH TLV. Conclusions: This work evaluated the sculptors' exposure to particulate matter and noise in fine art college, and revealed a poor working environment for the participating students. Effective measures should be supplemented by the administration of colleges.

Special health examination institute has done periodic health examination for workers who have worked in the hazardous workplace. However, assessment on outcome in special health examination institute about detection ability of occupational disease has not been. In this circumstances, we studied on the differences of health examination outcome among special health examination institutes and identified related factors which affected outcome of special health examination in the special health examination institutes. The summary of the results were as follows. 1. 50 special health examination institutes were examined in this study. Among them, university institutes were 13 cases(26.0%), hospitals were 20 cases(40.0%), a corporation aggregates were 9 cases(18.0%) and an auxiliary organs of company were 8 cases(16.0%). There were 29(58.0%) institutes with a preventive medicine specialist, but 21 institutes(42.0%) were not. 2. Total workers examined in 50 institutes were 606,948 and workers diagnosed as occupational disease$(D_1)$ were 3,156. The rate of occupational disease was 6 workers per 1,000 examined workers. Workers needed for close observation(C) were 95,809 and the rate of workers needed for close observation was 141 per 1,000 examined workers. 3. The rate of occupational disease of university institutes was highest(11.3 per 1,000 examined workers), and followed by hospitals(6.0 per 1,000 examined workers), a corporation aggregates(4.2 per 1,000 examined workers), and an auxiliary organs of company(1.2 per 1,000 examined workers). The difference of the rate of occupational disease between university institutes and an auxiliary organs of company was statistically moderate significant(p<.1). The rate of occupational disease in special health examination institutes with establishment duration was more than 10 years was statistically higher than institutes with establishment duration was less than 10 years(p<.1). 4. The results of multiple regression, $R^2$ was 0.3394(adjusted $R^2$ was 0.2109), F-value was 2.6416(p<.05), and statistically significant variables were establishment duration(p<.01), number of examined workers per one doctor(p<.1), and auxiliary organs of company(p<.1), which dependent variable was the rate of occupational disease and independent variables were number of examined workers per one doctor, classification of institute, the rate of working environment exceeding TLV, duration of institute establishment, presence of a preventive medicine specialist.

The occupational health problems are the major issue in the modern industrial society. Especially the small scale industries have many hazardous factors and not any occupational health programs in itself. Fortunately. the government-funded subsidiary program was developed and carried out in the past six years in our country. The purposes of this study were to find out the actual condition of the occupational health personnel's accomplishments for the government-funded subsidiary program for small scale industries and to provide basic data for setting up more developed subsidiary occupational health program. Data were collected through 6 kinds of service records review. These service records were written by 3 occupational health personnels were attached to the one subject center of KIHA. were undertaken during March to December, 1997. at 95 small scale industries which were applied the government-funded subsidiary occupational health program. Results were as follows 1. Concerning 95 small scale industries showed characteristics of a typical small scale industry. 2. A doctor visited in industries total 190 times per year, average 19 industries per month, twice per year and industry. A hygienist visited in industries total 378 times per year, average 38 industries per month, four times per year and industry. A nurse visited in industries total 477 times per year. average 47 industries per month, 5 times per year and industry. 3. 3 occupational health personnels accomplished total 3,869 items. A doctor accomplished total 539 items per year, each time 3 items In an industry. A hygienist accomplished total 1.581 items per year, each time 4 items in an industry. A nurse accomplished total 1.749 items per year, each time 4 items in an industry. 4. The major contents of doctor's accomplishment were 'health consultation for suspicious worker with general & occupational disease', 'a check of the workplace & special health education', 'guidance of special medical examination in the second half of year', etc. The major contents of hygienist's accomplishment were 'pretest & guidance of planning for evaluation of working environment'. 'evaluation for ventilating facilities & suporting self inspection', 'guidance of MSDS recording & chemicals management', etc. The major contents of nurse's accamplishment were 'health counseling of general & special medical examination results'. 'health education of preventing occupational disease & health disorder'. 'guidance of subsidiary program planning', 'selecting & guidance of health monitor', etc. It was concluded that the occupaional health personnels implemented the subsidiary program according to the order of health management guide. The current health management guide of subsidiary occupational health program in which the fixed contents, visiting number & periods is not desirable. That guide is left the characteristics of small scale industries out of consideration. It is suggested that occupational health management guide should be developed according to the general & environmental characteristics of each small scale industry, and on the other hand, the more specific guide for each occupational health personnel should be developed.

Objectives: In this study, an evaluation of the working environment of furnace workers was performed and the work-relatedness of the occupational diseases were examined Methods: In this study, two electric furnaces at a single casting business site producing manganese-based iron alloy were selected, and occupational exposures to hazardous substances were evaluated for furnace workers and furnace worker assistants. Results: As a result, total dust concentration were $0.407{\sim}3.001mg/m^3$ and respirable dust concentration were $0.196{\sim}0.584mg/m^3$. The highest concentration of crystalline silica was $0.079mg/m^3$ In the case of Masato and Sosuckwhoi crystalline silica, they contained 90.85% and 4.17% respectively. Manganese concentration was the highest at a $0.205mg/m^3$ maximum. The average of black carbon is $11.56{\mu}g/m^3$ and the maximum concentration is $604.23{\mu}g/m^3$. PAHs concentration was the highest at a $78.301{\mu}g/m^3$ of naphthalene. The concentration of carbon monoxide was 18.82 ppm(total average 3.89 ppm) during pouring, and the maximum is 131 ppm. The formaldehyde concentration was 0.003 to 0.007 ppm. Conclusions: It seems that conditions in the past were worse, since casting has recently been performed only twice per day for about 20 minutes, reducing the amount of pouring, and local exhaust systems have been installed one-by-one. In addition, it was judged that the past exposure levels were higher considering the points measured on the back-side due to the risk of damage to the individual samples. It was found that operators could be exposed to high concentrations of crystalline silica, and that they were also exposed to high concentrations of metal(fume) and carbon monoxide during pouring. Therefore, there is a risk that occupational diseases such as lung cancer and COPD may occur with long-term work in such a process.

현대 사회는 뜻밖의 사고와 위험 상황으로 불안정한 환경에 직면하고 있다. 예를 들어 분당 다리 붕괴사고와 이태원 압사사고 등이 그 예가 될 것이다. 이와 함께 급성심정지나 뇌졸중과 같은 중대한 응급상황이 발생하였을 때, 신속한 조치와 전문 의료 기관으로의 원활한 이송이 필요한 경우 또한 빈번하게 발생하고 있다. 이러한 위험 요소에 대응하기 위해 국가는 국민의 생명과 안전을 보호하기 위한 다양한 시스템을 구축하고 있는데, 119구급대는 응급 의료 시스템 중 핵심적인 역할을 수행한다. 중대한 외상 환자나 중증 질환 환자의 응급 상황에 즉각적으로 대응하여 손상을 최소화하고, 응급의료 기관으로 신속하게 이송하여 전문적인 치료를 제공함으로써 환자의 생명과 안전을 보호하는 것이 그 목표이다. 이와 관련된 핵심 활동이 구급활동인 것이다. 특히, 119구급시스템은 응급 환자의 병원 이송을 책임지는 핵심 기관이나, 구급대원들은 업무수행 중 구급활동 방해 사례에 여전히 직면하고 있다. 이러한 방해 사례는 경찰의 협조 노력에도 불구하고 줄어들지 않고 있고, 구급활동은 공무집행 방해죄와 유사한 특성을 지니며, 응급의료 시스템 내에서 근무하는 응급의료 종사자에 대한 폭행 및 장비 파손과 같은 사례와도 유사한 형태를 보인다. 따라서 119구급시스템을 포함한 응급 의료 활동을 수행하는 과정에서 발생하는 방해 문제에 대한 심층적인 이해와 개선 노력이 필요하다. 이러한 문제에 대한 해결책은 "소방기본법"과 "119구조·구급에 관한 법률"을 중심으로 구급활동 방해죄의 조건을 정립하고 개선하는 것이다.

Introduction: Biological risks are a major global problem in the workplace. The recent COVID-19 pandemic has highlighted the need for a more comprehensive understanding of the biological risks at work. This study presents data on both communicable infectious biological agents and noncommunicable factors leading to death and disability for the year 2021. Methods: We followed the methodology established by the International Labour Organization (ILO) in their past global estimates on occupational accidents and work-related diseases. We used relevant ILO estimates for hazardous substances and related population attributable fractions derived from literature, which were then applied to World Health Organization mortality data. The communicable diseases included in the estimates were tuberculosis, pneumococcal diseases, malaria, diarrheal diseases, other infectious diseases, neglected tropical diseases, influenza associated respiratory diseases and COVID-19. Noncommunicable diseases and injuries considered were Chronic Obstructive Diseases (COPD) due to organic dusts, asthma, allergic reactions and risks related to animal contact. We estimated death attributable to biological risk at work and disability in terms of disability adjusted life years (DALYs). Results: We estimated that in 2022, 550,819 deaths were caused by biological risk factors, with 476,000 deaths attributed to communicable infectious diseases and 74,000 deaths caused by noncommunicable factors. Among these, there were 223,650 deaths attributed to COVID-19 at work. We calculated the rate of 584 DALYs per 100,000 workers, representing an 11% increase from the previous estimate of the global burden of work-related disabilities measured by DALYs. Conclusion: This is a first update since previous 2007 ILO estimates, which has now increased by 74% and covers most biological risks factors. However, it is important to note that there may be other diseases and deaths are missing from the data, which need to be included when new information becomes available. It is also worth mentioning that while deaths caused by major communicable diseases including COVID-19 are relatively rare within the working population, absences from work due to these diseases are likely to be very common within the active workforce.

The small scale industries which have less than 30 employees occupy 86.5% of total number of industries in Korea. And though they have higher accident rate and lower environmental condition than big industries, it has been not mandatory to appointing health care manager at factory. So, from 1993, government subsidizes to the health care management of small industries. The purpose of this study is to identify the real feature of health care status in small industries, and to evaluate the level of health care management, before and after the subsidiary program. 65 small plating industries which have been managed by the same health care management support institution in 1993 were selected for study. Of the 65 industries, 3 which have not taken both environmental evaluation and health screening in 1994, and 9 which have closed were excluded from study sample. And the remaining 53 were analyzed by using the results of environmental evaluation and health screening, reported to the Ministry of Labor, before and after the subsidiary program, the analysis was done by the comparison of the two year paired data of the same industry. Over-permissible-limit rate, health screening implementation rate, above grade C rate were calculated and compared. The status of health care management ; 1. Of the sample industries, 96.9% provide protective equipment and 80.0% set up ventilating system. Protective gloves (89.2%) and protective clothing (80.0%) are widely provided, but ear plugs (4.6%) are rarely provided. 21.5% of the protective equipment are well put on, and 40.4% of the ventilating systems function well. 2. In 1993, 35 industries, 53.8% of the sample, checked working environment twice. Over-permissible-limit rates of heavy metal (12.2%), suspended particle (11.1%), noise (5.5%) were high. To put on protective equipment and to set up local ventilating system were pointed out by the examiners. 3. General health screening was done at 63.1% of the sample industries and 35.3% of total workers were examined. Specific health screening was done at 93.8% of the sample industries and 75.4% of workers were examined. 15.5% of workers was provided to be above grade C and to have digestive system disease (43.3%), circulatory disease (18.9%), and hematopoietic disease (14.2%), etc. 4. In 1993, the subsidiary program of health care management was provided in forms of health education, health counseling, and rounding check of working field. And 61.5%, 83.0%, 55.4% of sample industries respectively received it. The average visit per industry was 1.8. Comparisons of the level of occupational health before and after the subsidiary program ; 1. Over-permissible-limit rates of hazardous factors of 1993 and that of 1994 were compared. The rates of suspended particle, noise, organic solvent of 1994 (37.5%, 13.4%, 24.2% respectively) were higher than that of 1993 (25.0%, 6.0%, 6.3% respectively). In the case of acid, there was no difference between the rate of 1993 and that of 1994. Only the rate of heavy metal decreased from 12.9% in 1993 to 3.0% in 1994. 2. General health screening was done at 38.7% of the sample industries in 1993 and at 44.6% in 1994. But the implementation rate of specific health screening decreased from 72.4% in 1993 to 64.6% in 1994. 3. The implementation rate of specific health screening was analyzed by some health factors. The rate of suspended particle increased from 61.8% in 1993 to 91.2% in 1994. But the rates of the others-noise, organic solvent, heavy metal, specific chemical substances-decreased. 4. Above grade C rate in health screening increased from 27.8% in 1993 to 35.5% in 1994. But that of endocrine disorders and pulmonary disease decreased.

오염토양을 효과적으로 진단하고 경제적인 복원을 위해서는 오염토양의 오염원인, 오염정도, 주변 환경이나 인축에 대한 피해발생 유무, 오염물의 이동경로 등을 올바르게 평가하는 것이 대단히 중요하다. 이를 위해서는 오염토양과 토양내 가스, 주변 지하수 및 지표수, 침전물 등의 효율적 시료채취와 정확한 분석이 필수적이라 할 수 있다. 오염지역 토양의 오염도평가를 표준화하고 처리효율성을 높이기 위해서는 전문처리요원이 토양의 오염도와 위험성을 정확하게 판단 할 수 있도록 단순하면서도 경제적인 연속시험법을 필요로 한다. 이것은 오염토양의 조사와 복원시간 및 전치적일 기술의 진보를 가져오는데 상당한 시간절약을 꾀할 수 있다. 특히 효과적인 현장평가를 위해서는 오염특성을 포함한 많은 관련 요인들에 대한 표준화된 기준하에서 오염의 형태와 정도를 결정하는 것이 중요하다. 현장평가를 위한 일반적인 절차는 작업계획과 토양조사수준에 따라 Phase I, II, III의 단계적 방법으로 구성되어 있다. Phase I은 토양의 과거용도 및 오염물의 유입경로를 기초로 하여 현장의 환경여건을 파악하는 단계이다. Phase I에서 잠재적 오염물질에 의해 오염된 것이 확인되면 Phase II에서는 오염물의 존재여부와 존재정도를 파악하는 단계로 시료의 채취 및 분석과정이 여기에 포함된다. Phase III는 Phase I과 II의 결과를 바탕으로 오염토양을 복원하는 단계이다. 여기서 평가기준이 지역 특이적인 것인지 적당한 것인지를 결정하는 중요한 요인은 (1) 시료채취의 공간분포도와 지역의 크기, (2) 취해진 시료의 수, (3) 시료채취 방법, 그리고 (4) 자료를 분석요령 등이다. 선택된 분석방법이 추천할만한 것일지라도 정량방법의 선택여부는 현장조사방법에 대한 훈련이나 조사경험을 가진 사용자에 의해 결정되는 것이 바람직할 것이다.
