  • Objective: This study was undertaken to systematically assess and summarize the effects of acupuncture on cortisol secretion. Materials and methods: We searched articles published up to May 2010 in six electronic databases (PubMed, Cochrane Library, KISS, KISTI, DBPIA, Kyobo Scholar). Randomized clinical trials (RCTs) which met all the inclusion criteria were reviewed. Eight RCTs were finally selected for this systematic review and assessed by three reviewers. The risk of bias was also estimated by using the Cochrane criteria. Results: Six RCTs reported no distinct difference of cortisol levels between control and experimental groups. Two RCTs reported significant differences of cortisol levels between groups; one reported the acupuncture group with markedly higher concentrations of cortisol while the other reported the opposite result. Conclusion: There are some difficulties in clearly identifying the effects of acupuncture on cortisol levels in this systematic review due to inconsistent results. Therefore, more rigorous trials with larger scales need to be conducted to clarify the effects of acupuncture on cortisol levels.

  • 제4차 산업혁명이 대두되며 다양한 산업들의 기술들이 융·복합 되거나 클라우딩 컴퓨팅, 모바일, 빅테이터 등의 기술로 인해 인류의 삶이 물질적이나 정신적으로 크게 변화하고 있다. 다양한 기술과 이에 맞는 새로운 직업의 탄생은 전통금속공예기술에 대한 교육과 직업에 있어 대중의 외면을 가져오고 있다. 이런 변화에 있어 공예교육 또한 현 시대에 맞는 교육방식을 찾고 연구하며, 교육 현장에 적용해 대중의 관심과 부흥을 일으켜야 한다. 이를 위해 새로운 소재 혹은 기술이 도입된 타 산업의 교육현장 사례를 조사하고 전통금속공예기법 교육에 활용하고자 한다. 또한 3D프린팅 기술의 다양한 사례와 특징을 조사하고 시간과 공간, 자원의 제약이 많은 공예기법 교육에 활용하여 전통금속공예기법 교육에 새로운 변화를 주고자 한다.

  • 듀이십진분류법(DDC)은 문헌분류체계로 도서관에서 뿐만 아니라 인터넷자원을 분류하는 기반으로 사용되고 있는데, 이는 DDC가 주기적이며 지속적인 용어 확장을 통해 최신성과 실용성을 유지하기 때문이다. 반면, 한국십진분류법(KDC)은 비정기적인 개정 주기로, 용어의 최신성과 실용성이 떨어진다. KDC가 도서관뿐만 아니라 인터넷자원 분류에도 활용 가능하기 위해서는 실용적인 분류 항목명이 반영되어야 한다. 본 연구에서는 인터넷 자원의 디렉토리 분류체계와 KDC에서 사용하고 있는 분류항목명을 비교 분석하고 KDC에 추가할만한 분류항목명을 확장 제안하였다. 네이버, 야후, 교보문고, 아마존의 디렉토리 분류체계에서 음식문화 분야의 용어를 분석하였으며, 다른 분류체계를 참조하여 KDC로의 적용 방안을 제안하였다. KDC에 추가적인 분류항목명이 필요한 분야는 식품위생, 음료기술, 식품공학, 식품과 음료, 식사 및 식탁차림, 주방, 식당 공간이었으며 부족한 항목명은 음식 관련 용어 및 한식 관련 요리명이 주를 이루었다. 본 연구를 통해 KDC의 부족한 항목명과 적용방안을 제시함으로써 KDC가 도서관과 인터넷자원 분류에 활용될 수 있는 기반을 마련하였다.

  • Background: Due to the diversification and advancement of research, researchers have become to deal with a variety of chemical and biological harmful materials in the laboratories of universities and research institutes and the risk has increased as well. Therefore, it is necessary to strengthen the social safety net for laboratory accidents by strengthening the compensation to the level comparable to that of Korean Workers' Compensation & Welfare Service, when the researchers become physically disabled by laboratory accidents. The purpose of this study is to secure researchers' health rights and to create a research environment where researchers can work with confidence by strengthening the compensation to the level comparable to that of Korean Workers' Compensation & Welfare Service. Method: We analyzed the laboratory accidents by year, injury type, severity of accident and disability grade with the 6 year data from 2011 to 2016, provided by Laboratory Safety Insurance. Based on the analysis result, we predicted the financial impact on Laboratory Safety Insurance if we introduce a compensation annuity by disability grade which is similar to Injury-Disease Compensation Annuity of Korean Workers' Compensation & Welfare Service. Result :As of 2011, the insured number of Laboratory Safety Insurance was approximately 700,000. The Average premium per insured was KRW 3,339 and there were 158 claims. Total claim amount was KRW 130 million, whereas the premium was about KRW 2.3 billion. The loss ratio was very low at 5.75%. If we introduce a compensation annuity by disability grade similar to Injury-Disease Compensation Annuity of Korean Workers' Compensation & Welfare Service, the expected benefit amount for 1 case of disability grade 1 would be KRW 1.6 billion, assuming 2% of interest rate. Given current premium, the loss ratio, the ratio of premium income to claim payment, is expected 41.4% in 2017 and 151.6% in 2026. The increased loss ratio due to the introduce of the compensation annuity by disability grade is estimated to be 11.0% in 2017 and 40.4% in 2026. Conclusion: Currently, laboratories can purchase insurance companies' laboratory safety insurance that meets the standards prescribed by Act on the Establishment of Safe Laboratory Environment. However, if a compensation annuity is introduced, it would be difficult for insurance companies to operate the laboratory safety insurance due to financial losses from a large-scale accident. Therefore, it is desirable that one or designated entities operate laboratory safety insurance. We think that it is more desirable for laboratory safety insurance to be operated by a public entity rather than private entities.
