Objectives: This study was performed in order to establish reliable and relative selection criteria for hazardous substances requiring management(HSRM) in the Occupational Safety and Health Act in Korea. Methods: To determine the relative criteria and weight of evidence for HSRM, we analyzed the difference between the selection method of priority substances in studies by KOSHA(Korea Occupational Safety and Health Agency) and the European Union Risk Ranking Method(EURAM). In addition, 597 hazardous substances with exposure limit valueswereanalyzed and the posted health hazards classification by MOEL(Ministry of Employee and Labor), MOE(Ministry of Environment), and EU CLP(Classification, Labelling and Packaging regulation) were compared based on GHS(Globally Harmonized System of classification and labelling of chemicals) criteria. The existing HSRM(167 substances) were evaluated for suitability by the proposed criteria in this study. Results: As a result of this study, the criteria and procedures for selecting HSRM in the Occupational Safety and Health Act were arranged utilizing GHS health hazard classification results, occupational disease cases and domestic use situations. Conclusions: The applicability of the proposed criteria was proved via the evaluation of existing HSRM(167 substances). Most HSRM (161 substances) were found to correspond to a significant health effect or substantial health effect. The question of whether to include the six substances that have been found to have general health effects as HSRM would be require further research.

국내 현행법상 개인정보 국외이전은 정보통신망법과 개인정보보호법에서 정보주체의 동의하에 국외이전을 허용하여 왔다. 하지만 최근 IT기술의 발달과 더불어 다국적 기업들의 국내 진출, 클라우드 활성화, FTA 협정 등을 통해 국가간 개인정보이전이 증가하는 가운데 현행 규제는 개인정보 국외이전에 뚜렷한 방향성을 제시하지 못한다. 개인정보의 국외 이전 활성화는 국제협력 강화와 개인정보의 유통을 기반으로 하는 금융, 인터넷, 전자상거래 등 다양한 산업의 발전에 기여하는 바가 크며, 변화하는 정보통신기술 환경에 필수적인 요건이다. 따라서 개인정보의 보호의 원칙을 고수하며 개인정보의 해외 이전에 유연하게 대처하기 위해서는 새로운 개인정보이전 체계 마련에 대한 논의가 필요하다. 본 연구는 현행 개인정보 국외이전 법규의 한계와 새로운 제도의 필요성을 검토하고, 유럽의 개인정보 국외이전 사례 분석을 통해 정책 대안을 제시한다.

Objectives: The major objective of this study was to analyze insomnia after the change to consecutive day shift from day and night shift in a motor assembly factory. Materials: Data were collected at before and after shift system change through a survey conducted by a labor union. We analyzed transition of PSQI(Pittsburgh Sleep Quality Index) among 222 workers by separating the day shift week and night shift week. The cut-off point of insomnia was 8.5 on the PSQI. Results: Mean PSQI in the day shift week significantly did not decrease, going from $6.36{\pm}3.23$ to $6.46{\pm}3.00$(p=0.612 by paired t-test), Mean PSQI for night shift week significantly decreased from $8.31{\pm}3.36$ to $6.19{\pm}3.18$(p<0.001 by paired t-test). However, mean PSQI in the day shift week increased from $6.33{\pm}3.83$ to $7.11{\pm}2.86$ in ${\geq}50$ years(p=0.085, by repeated measured ANOVA). Mean PSQI score in the night shift week improved more in the married group(from $8.38{\pm}3.27$ to $6.12{\pm}3.18$) than in the non-married group(from $7.82{\pm}3.27$ to $6.12{\pm}3.18$)(p=0.038, by repeated measured ANOVA). Conclusions: The change to consecutive day shift improved insomnia in night shift. However, insomnia in the day shift week was worsened among those more than 50 years old.

Objectives: The major objectives of this study are to review the issues surrounding trade secret claims in the Chemicals Control Act and Amendment on Occupational Safety and Health Act(1917-227) and to propose a way of improving the reliability of chemical information in MSDSs, labels and National Chemical Survey results. Materials: To review the issues on trade secret claims, we made an analysis frame which was divided into three steps: Value and Problem Recognition; New Regulation Design; and Enforcement and Amendment. We then compared Korean issues with issues from the United States' Hazard Communication Standard and Emergency Planning & Community Right-to-Know Act, Canada's Workplace Hazardous Materials Information System and Hazardous Materials Information Review Act and the European Union's Regulation on Classification, Labelling and Packaging of substances and Mixtures. Results: The stage of right-to-know development in Korea has passed the Value and Problem Recognition phase, so efforts are needed to elaborately design new regulation. Conclusions: We recommend two ways to improve right-to-know in Korea. First, strict examination of the quality of documents for trade secret claims is very important. Second, trade secrets should be limited to less-hazardous substances.

본 논문은 케로신 액체로켓엔진에서 세계 최고의 기술력을 갖고 있는 러시아와 우크라이나의 액체로켓 엔진 개발과정 및 동향을 살펴보았다. 구소련에서는 1960년대에 closed cycle을 채택하여 엔진의 연소압과 비추력을 최대한 높이는데 주력하였다. 그러나 1990년대 이후 경제적으로 어려워지면서 새로운 엔진개발에 드는 비용을 최소화하고 있으며, 이를 위하여 유사업종의 업체 간의 합병을 진행했고, 새로운 엔진개발에 기존의 부품을 최대한 사용하거나 시험-개선과정의 합리화를 통하여 시험엔진개수와 시험횟수를 줄이고 있다. 또한 국제 협력을 통하여 우주발사체시장에서 상업용 로켓을 위한 엔진 납품을 증가시키고 있다. 더불어 3성분이나 메탄 엔진 등 차세대 엔진 개발에도 주력하여 액체로켓엔진의 선두주자로서의 지위를 유지하려는 노력이 계속되고 있다.

This study was carried out to investigate awareness and attitude of monitors in 206 small sized industries in Seoul and Kyeonggi area toward the occupational health programs using a specially prepared questionnaire. The industries had been running Government-Funded Subsidiary Program since 1998. The questionnaire was designed to be self-administered by respondents. Data were collected for two months from November to December, 1998. Major results are as follows: 1. Between two groups of industries, there were no significant differences in classification, scale, methods of production, existence of trade union, but in type of working pattern and facility ownership there were significant differences. 2. Between two groups of monitors, there were no significant differences in gender, age, marital status, rank, years of education, but in duration of working there was a significant difference. 3. In awareness and attitude of monitors toward their activities and occupational health programs, there was no significant difference by groups of industries, but a significant difference by type and scale of industry, gender, age, years of education 4. It was found that newly subsidized industries were more necessary to provide education programs on occupational health than old industries, and there was a significant difference between two groups of industries in the contents of education needed. In conclusion, it is desirable that the government should develop specific training programs for monitors on occupational health to provide them practical knowledge and specific skills which monitors can apply to their specific situation, and implement the training programs and continue Government-Funded Subsidiary Program for years until small scale industries would have been able to develop and keep their own health management system spontaneously.

Aims: We have examined and analyzed trends of acupuncture related patents to understand the status of acupuncture technology and research trends of acupuncture in major countries including Korea, the United States, European Union and Japan. Methods: To analyze the patents, we searched and analyzed the total of 1,048 on-line DB based patents under time limit of July, 2006. Results: According to the search results, Korea is mostly superior compared to the others in number of domestic patents. However, Korea patents is inferior in number of international patents and leave much to be desired in industrial applications because of low patents barrier of personal patents and the absence of prospective clients. In addition, in this study, we show an index of international competitiveness and preliminary data of necessity of international cooperation in a field of acupuncture researches. Conclusion: These data suggest that Korea has strong possibility to recover competitiveness for guaranteeing valuable patents, if there are international cooperation and intensive managements of industries in advanced country markets.

Objectives: To review reference levels by the international and domestic management and provide the basis for setting occupational exposure limits(OELs) of radon in Korea Methods: Government's organizations with laws and systems for monitoring radon exposure were investigated and compared. There are five laws governing Indoor Air Quality(IAQ) control such as Occupational Safety and Health Act, Indoor Air Quality Control in Public Use Facilities, Etc. Act, School Health Act, Public Health Control Act and Parking Lot Act in Korea. It was surveyed that a total of 32 countries including 24 countries in the European Union(EU), six countries in Asian and two countries in North America setting the reference levels for radon in the world. Results: In Korea, there are set guidelines for radon in the Ministry of Environment and the Ministry of Education. Reference levels of radon for existing dwellings were $150{\sim}400Bq/m^3$ for Western European countries, and $200{\sim}1,500Bq/m^3$ in Eastern European countries. Approximately 67% of those EU countries were set up $400Bq/m^3$ to the standards for existing dwellings. EU countries such as Luxembourg, Finland, Norway, Sweden and Russia had adopted mandatory level for radon. Radon guidelines for new dwellings were set more strictly reference level($200Bq/m^3$) than existing dwellings. Conclusions: International organizations such as ICRP, UNSCEAR and NCRP, etc. had recommended the guidelines for radon. It was calculated the relation of the dose conversion factors with the annual effective doses. the OELs of radon suggest to need to establish $150Bq/m^3$ for office room and $400{\sim}1,000Bq/m^3$ for the workplace.

Objectives: This study was conducted to evaluate asbestos handling history of workers at automobile manufacturing plants in Korea. Methods: National regulations on asbestos and Korea Occupational Safety and Health Agency(KOSHA) database on the information of asbestos containing products were reviewed. We investigated asbestos related materials from one automobile manufacturing plant. Material safety data sheets(MSDS) collected in 2010, work environment monitoring results reported from 2000 to 2013, trade union reports and asbestos survey reports were reviewed. We also interviewed workers with long career and did walk-through survey. Results: The Ministry of Labor in Korea has permitted asbestos manufacturing since 1990. In 1997, the use of crocidolite and amosite asbestos were banned. In 2007, the Korean government announced a total ban on the manufacturing, importation and use of all kinds of asbestos, which took full effect in 2009. A total of 174 asbestos products information from KOSHA database was analyzed. Extruded cement panel for building, special brake for crane farm machinery, gasket, joint sheet and thermal insulator were produced until 2007. From automobile manufacturing plant survey, we confirmed that asbestos containing materials(ACM) such as gasket, heating induction materials have been used until 2011. Asbestos containing building materials(ACBM) such as bamlites, slate and ceiling tex were reported at 122 asbestos dismantling projects in 2014. Conclusion: Although the use of all kinds of asbestos were banned from 2009, ACMs and ACBMs installed before 2009 were still found at automobile manufacturing plant until 2011 and 2014 respectively. In particular, asbestos slates should be managed because most of slates had not been removed until 2014.
