Objectives This study is conducted to estimate the cost paid by the public suffering from disease possibly caused by chemical and to examine the effect on public health. Methods Cost-benefit analysis is an important factor in analysis and decision-making and is an important policy decision tool in many countries. Cost-of-illness (COI), a kind of scale-based analysis method, estimates the potential value lost as a result of illness as a monetary unit and calculates the cost in terms of direct, indirect and psychological costs. This study estimates direct medical costs, transportation fees for hospitalization and outpatient treatment, and nursing fees through a number of patients suffering from disease caused by chemicals in order to analyze COI, taking into account the cost of productivity loss as an indirect cost. Results The total yearly cost of the diseases studied in 2012 is calculated as 77 million Korean won (KRW) per person. The direct and indirect costs being 52 million KRW and 23 million KRW, respectively. Within the total cost of illness, mental and behavioral disability costs amounted to 16 million KRW, relevant blood immunological parameters costs were 7.4 million KRW, and disease of the nervous system costs were 6.7 million KRW. Conclusions This study reports on a survey conducted by experts regarding diseases possibly caused by chemicals and estimates the cost for the general public. The results can be used to formulate a basic report for a social-economic evaluation of the permitted use of chemicals and limits of usage.

Background : The objective of this study was to examine the effect of management system for the appropriate prophylactic use of antibiotics in surgical patients at a tertiary hospital from 2007 to 2010. Methods : We collected clinical data of three different surgical procedures(colectomy, heart surgery, hysterectomy) for three months of 2007 and 2010, respectively. The number of total cases was 245(137, 54, 54) in 2007, 240(133, 42, 65) in 2010. We measured the rate of use of inappropriate prophylactic antibiotics, administration within 1 hour prior to the incision and the antibiotics prescription days after surgery. To evaluate the effectiveness of the management system, the results of the two groups(Group1=2007, Group2=2010) were compared by t-test, chi-square test or Fisher's exact test. Result : The rate of Aminoglycoside uses decreased drastically from 11.4% to 0.8%(P<.001). The selection of 3rd/4th Cephalosporin dropped from 11.8% to 5.8%(P=.020). The combination of antibiotics decreased from 27.8% to 11.7%(P<.001). The antibiotic prescription rate on discharge declined from 11.8% to 2.5%(P<.001) and the number of antibiotics prescription days after surgery was shortened from 4.2 days to 2.3 days(P<.001). No significant difference in the rate of administration within 1 hour between two groups was found. Through 3-year management, 5 out of 6 measures were significantly improved(except the administration within 1 hour). The rate of surgical site infection decreased from 2.4% to 1.3%(P=.504). Conclusion : The findings demonstrate that the management system for the prophylactic use of antibiotics in surgical patients was effective in decreasing the rate of surgical site infection during 3 years.

본 연구에서는 국내 23개의 교육출판사를 대상으로 자료포락분석(DEA)를 활용하여 2018년부터 2021년까지의 연도별 효율성을 측정하였다. 또한, 본 연구에서는 출판사 효율성 변동에 영향을 미치는 출판사 운영 변수를 도출하여 이러한 출판사 운영 변수들이 효율성에 어떠한 영향을 미치고 있는지를 Simar와 Wilson(2000)이 제시한 이단계 부트스트랩 단절회귀분석을 통해 분석하였다. DEA 분석 결과에 의하면, 최근 4년간 출판사의 기술 및 순수기술 효율성은 지속적으로 감소하고 있으며, 특히 코로나 19 발생 이후인 2020년 이후에는 평균 효율성이 급격히 감소하였다. 이와 같은 효율성 감소의 주요 원인으로는 규모의 비효율로 인하여 효율성이 감소한 것으로 분석되었다. 또한 교육출판사의 효율성에 영향을 미치는 출판사의 전략적 운영변수로 지급수수료, 지급임차료, 운반비 등이 효율성에 통계적으로 유의한 영향을 미치는 것으로 분석되었다. 또한, 코로나19의 발생 전후 시기에 효율성을 변동에 영향을 미치는 출판사 운영변수들은 서로 다른 패턴을 보이고 있다. 본 연구결과는 최근의 어려운 환경에 놓여있는 출판사들의 효율성 제고 및 지속 가능한 성장을 도모하기 위한 실무적인 시사점을 제공하고 있다. This study used parametric data development analysis (DEA) to estimate the contemporaneous efficiency of 23 educational publishers in Korea from 2018 to 2021. Moreover, we employed a two-stage bootstrapped truncated regression to identify the internal factors affecting the operating efficiencies of educational publishers. According to the DEA results, the technical efficiency (TE) of educational publishers has continued to decline over the past four years, and the average TE has decreased mainly due to scale inefficiency after the outbreak of COVID-19 in 2020. In addition, payment fees, rental fees, and transportation costs as strategic operating variables of educational publishers have a statistically significant effect on their efficiency. This study provides practical implications for improving the efficiency and promoting sustainable growth of publishers.

The purpose of this study is to present desirable directions to strengthen educational function of museums in Korea based on the analysis of current practice and problems. Overall, the number of museums which provide educational programs has been rapidly increased in recent 10 years. Still, with the lack of know-how and institutional resources to develop quality education programs, educational function of museum is generally limited to exhibition. For their survival in the increasingly competitive and complex environment, however, museums need to make drastic change to meet the educational needs of the public and enhance their relevancy in society. The seven main problems of museum education in Korea with recommendations are presented in the areas of museum philosophy, infrastructure, and educational programming. First of all, a low institutional priority given to education is a fundamental barrier. While education and public access is stressed in written, official document, educational programs in practice are often neglected and undervalued from the main museum function with its top priority highly oriented toward collection and exhibition. As a result, there are not many sustainable and high-quality education programs. To remedy this situation, the paradigm shift of museum management must occur to place education as an essential tool to expand, sustain and satisfy ‘audience’ who are at the center of museum management today. Second, such a low priority in education results in the lack of institutional resource to develop educational programs. Organizational structure should be restructured to develop effective and professional educational programs. Alongside, training and staffing of professional educators are essential. Also at least 1% of total operating budget should be allocated for education. Third, five main problems in contents and planning of education programs are mentioned. Museum education should fully utilize museum collection and exhibition as a subject and purpose of the program. When their programs are not closely related to their assets, the strengths and uniqueness of museum education programs will diminish. Incorporation of educational approach unique to the nature of museum education is also needed. Various approaches such as interdisciplinary and multicultural education, utilization of new technology, and object-based learning would enhance the educational strengths of museums that are differentiated from schools and other educational institutions. Also museums need to develop a variety of educational materials available in and outside the museum. Print and media materials would be cost-effective distant learning tools to reach out to larger audience especially who cannot come to museums. Diversification and strategic development of program audiences are other concerns. Finally, a stronger partnership with diverse community organizations and schools in the planning and implementation of education programs needs to be established to solicit new ideas and resources and enhance ‘relevancy’ to its community. Based on the analysis of current practice and problems in museum education stated above, in conclusions, recommendations for government policy to facilitate museum’s educational function were proposed. A separate division in the Ministry of Culture and Tourism to support arts education or a grant-making program solely dedicated to museums’ educational endeavor would be one effective way to motivate and facilitate the educational role of museums.

Purpose: The purpose of the study was to examine the relationships among anxiety, depression, self-esteem, and quality of life in thyroid cancer patients with thyroidectomy and to identify factors influencing their quality of life. Methods: A cross-sectional survey was conducted to measure anxiety, depression, self-esteem, and quality of life of 129 thyroid cancer patients between 2011 and 2012. The data were analyzed with t-test, one-way ANOVA, post-hoc comparison (Duncan), Pearson’s correlation coefficients, and multiple regression analysis. Results: The mean age of the participants was 49.8, and most of them were female and married. The mean time since diagnosis of the participants was two years. The mean score for quality of life was 74 out of 108. Quality of life was significantly different by gender, employment and the stage of cancer at diagnosis. Anxiety, depression and self-esteem were all correlated to quality of life. As a result of stepwise multiple regression analysis, depression, self-esteem, and gender were discovered to account for 58.1% of the variance in quality of life. Depression was the most influential factor. Conclusion: The results of the study indicate that depression and self-esteem should be integrated when developing psychosocial intervention to promote quality of life among thyroid cancer patients.
