Objectives: This study identifies the trends in possible and probable occupational disease among chromium workers and reviews the literature on domestic and foreign chromium workers to review the industries, biological exposure levels, and major results. Methods: The results of the Ministry of Employment and Labor's special health-screening program for hazard agents among workers from 2009 to 2019 were used. Also, the industries, biological exposure levels, and major results on chromium workers were reviewed using PubMed and RISS. Results: The average annual proportion of both possible and probable occupational disease for chromium workers has recently increased. The average annual proportion of possible and probable occupational disease that can occur was high for both men and women in their 60s or older by age and 10 to 14 years by work duration. By industry, possible occupational disease showed high in manufacturing. In the literature review, many electroplating-related chromium-workers reported high levels of exposure to blood and urine chromium, as did dental technicians; tannery, tile factory or glass mill workers; cement workers; and sodium bichromate workers. Furthermore, a number of main findings in recent studies have reported that chromium exposure is related to genetic toxicity among workers. Conclusions: In this study, the average annual rate of both possible and probable occupational disease in domestic chromium workers is increasing, and a body of literature shows that chromium exposure is related to genetic toxicity and associated indicators among workers, which requires more systematic study.

Since 2015, the Health Insurance Review and Assessment Service (HIRA) has performed annual qualitative assessments of asthma management provided by all medical institutions that care for asthma patients in Korea. According to the third report of qualitative assessment of asthma management in 2017, the assessment appears to have contributed to improving the quality of asthma care provided by medical institutions, especially primary clinics. However, there is still a gap between the ideal goals of asthma management and actual health care policies/regulations in real clinical settings, which leads to the state of standstill with respect to the quality of asthma management despite considerable efforts such as the qualitative assessment of asthma management by national agencies such as the HIRA. At this point, a harmonized approach is needed to raise the level of asthma management among several components including medical policies, efforts of academic associations such as education and distribution of the guideline for management, and reliable financial support by the government.

1999년부터 20세대 이상의 신규 주택분양시 분양가격 규제가 철폐되었다. 2001년 이후 아파트를 중심을 가격이 상승하자 그 원인이 신규 주택의 분양가격이 상승하였기 때문이라는 주장이 나오면서 분양가를 다시 규제해야 한다는 의견이 나오고 있다. 본 연구는 분양가격의 상승 실태와 재고 주택가격간의 관계를 고찰하여 분양가격 규제가 필요한지 여부를 검토한다.

The purpose of this study was to examine the changes of kitchen space based on the additional functions since 1960s'. The review of literature was performed to accomplish the purpose. The changes of paradigm of kitchen space due to the social, technological, cultural factors had made the additional functions of kitchen more complicated, and further, resulted in changes of floor plans of housing as well as kitchen space.

이 보고서는 국제원자력기구(IAEA, International Atomic Energy Agency) 회원국의 요청에 의해 매2년마다 발간되는 “원자력 기술 분석(Nuclear Technology Review)을 요약한 것이며, 2005년 말을 기준으로 발간된 것이다. 원 보고서에 포함된 내용은 원자력 발전, 핵융합, 핵연료, 방사성 동위원소 및 방사선, 관련 연구 개발 등에 대한 오늘과 향후 발전상을 검토한 것이나 여기서는 원자력 발전을 중심으로 요약했다. 보다 궁금한 사항은 IAEA 연례보고서인 2006년 Annual Report에서도 볼 수 있으며 홈페이지인 WWW.iaea.org을 방문하여 영어로 된 보고서를 접할 수 있다. 이 보고서를 요약한 것은 IAEA에서 보는 각국 및 세계 원자력의 현황과 전망을 소개함으로써 국내의 많은 원자력 가족 및 원자력산업에 조금이라도 도움이 되었으면 하는 데 있다.

This paper shows that various fractionally integrated univariate and multivariate are remarkably successful in representing annual temperature series and also very long series of tree ring widths, which are often used as a proxy for temperature. The analysis also suggests that human recorded temperature series are not inconsistent with being generated by a stationary, long memory process. From the empirical results, we should be noted that the statistically significant positive trend coefficients may well be due to small sample sizes. These results cast some doubt on the basic assumption that global warming is definitely occurring.

The seasonal adjustment is an essential process in analyzing the time series of economy and business. There are various methods to adjust seasonal effect such as moving average, extrapolation, smoothing and X11. One of the powerful adjustment methods is X11-ARIMA Model which is popularly used in Korea. This method was delivered from Canada. However, this model has been developed to be appropriate for Canadian and American environment. Therefore, we need to review whether the Xl1-ARIMA Model could be used properly in Korea. In this study, we have applied the method to the annual sales of refrigerator sales in A electronic company. We appreciated the adjustment by result analyzing the time series components such as seasonal component, trend-cycle component, and irregular component, with the proposed method.
