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.

양진원(Jinwon Yang), 양지연(Jiyeon Yang), 최강화(Kanghwa Choi) 한국생산관리학회 2023 한국생산관리학회지 Vol.34 No.2

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.

본 연구는 Carl Gustav Jung의 그림자 이론을 중심으로 연구자의 그림자 인식에 따른 미술치료를 통해 자기 치유와 내적 성장의 경험을 얻고자 하였다. 연구자는 연구 과정을 통하여 불안이라는 감정의 실체를 이해하고 실존적인 물음에 답을 찾아가며 자기 경험의 의미를 기록해 나가는 현상학적 탐구 방식으로 전개하였다. 이를 위해 2023.10.12.~2023.12.08 매주 1회 약 30분씩 10회기 미술치료를 실시하며 본 연구를 진행하였다. 본 연구의 결과를 정리하면 첫째, 미술치료 과정에서의 그림자 인식은 무의식 내용과 의식화 과정, 실체로서의 그림자, 그림자의 의식화 과정, 마음 세계에서의 그림자 자리 단계를 거치며 내면의 미해결된 상처와 감정을 회복하는 과정을 경험하였다. 둘째, 미술치료 경험을 통해서 자신의 아픔에 다가가고 억압된 감정을 만나는 과정의 반복을 통해서 자기 치유와 내적 성장에 다다름을 경험하였다. 이런 연구 결과를 바탕으로 본 연구의 의의와 제한점에 대하여 논의하였다. This study attempts to gain the experience of self-healing and internal growth through art therapy with focus on the researcher's shadow perception, focusing on the basic of Jung's shadow theory. In this process, the researcher developed a phenomenological inquiry method in which they understood the reality of the emotion of anxiety, sought answers to existential questions, and recorded the meaning of their experiences. This study was conducted by doing 10 sessions of art therapy once a week for about 30 minutes once a week from October 12, 2023 to December 8, 2023. The results of this study is summarized as follows; First, shadow recognition in the art therapy process enables the subjects to experience the process of recovering from the unsolved wounds and emotions through the process of consciousness of the shadow as the unconscious content and the finding of shadow positions in their mind world. Second, they experience self-healing and internal growth through the repetitive processes of approaching their pains and encountering suppressed emotions in this art therapy experience. Based on these findings, the significance and limitations of this study were discussed.

The aims of this study were to develop the suitable system software in chemical ranking and scoring (CRS) for the food hazardous chemicals associated with environmental emission and to suggest the priority lists of food contamination by environmental-origined pollutants. Study materials were selected with reference to the priority pollutants list for environment and food management from domestic and foreign research and the number of study materials is 103 pollutants (18 heavy metals, 10 PBTs, 10 EDs, and 65 organic compounds). The Food-CRS-Korea system consisted of the environmental fate model via multimedia, transfer environment to food model, and health risk assessment by contaminated food intake. We have established that health risks of excess cancer risks, hazard quotients (HQs) by chronic toxicity and HQs by reproductive toxicity convert to score, respectively. The creditable scoring system was designed to consider uncertainty of quantitative risk assessment based on VOl (Value-Of-Information). The predictability of the Food-CRS-Korea model was evaluated by comparing the presumable values and the measured ones of the environmental media and foodstuffs. The priority lists based on emissions with background-level-correction are 15 pollutants such as arsenic, cadmium, and etc. The priority lists based on environmental monitoring date are 17 pollutants including DEHP, TCDD, and so on. Consequently, we suggested the priority lists of 13 pollutants by considering the several emis-sion and exposure scenarios. According to the Food-CRS-Korea system, arsenics, cadmium, chromes, DEHP, leads, and nickels have high health risk rates and reliable grades.
