Although the variety and quantities of chemicals used have been increasing, no management strategies have been developed for these chemicals in our country. Therefore, it is important to identify the hazardous characteristics of chemicals and establish reasonable and effective management plans for them. However, because insufficient resources are available to evaluate all aspects of many varieties of chemicals, studies on suitable chemical ranking and scoring(CRS) system should be performed to ensure effective screening of priority chemicals. In addition, because most CRS systems have their own goals, it is impossible for only one generic system to be consistent with all the uses that have been developed. Therefore, priority systems should be developed with specific and clearly defined purposes in our nation. In this study, we investigated and discussed existing CRS systems, and proposed several elements and principles when designing CRS systems. First of all, the system should have clearly defined goals, keep neutral, and employ simple methods. In addition, researchers need to perform sensitivity analysis to find the main variables responsible for uncertainties and use the tiered approach to compose the effective management strategies for chemicals.

後漢 左傳學의 자연관과 災異說 ― 服虔의 『春秋左氏傳解誼』를 중심으로 ―

김예신 중국고중세사학회 2015 중국고중세사연구 Vol.37 No.-

The purpose of this article is to clarify the rationalistic features based on Zuo-zhuan(左傳) School’s view of nature and Zai-yi(災異) theory during the Later Han dynasty by analyzing Fu-qian(服虔)’s Annotation on Zuo-zhuan, Chun-qiu Zuo-shi Zhuan Jie-yi(春秋左氏傳解誼). The issue of rationalism in Fu-qian’s philosophy is not only the new interpretation about Zai-yi, but also the assertion of originality of Zuo-zhuan learning in Late Han dynasty. This contradicts two invalid research trends. Previous researchers do not substantially explain the reason why mystical perspective once accepted was replaced with rational perspective during Wei-Jin(魏晉) period because they adhere to thought that the Zai-yi theory of Gong-yang(公羊) Learning was the only conception that predominates the view of nature in Late Han dynasty. They also suppose that Zuo-zhuan(左傳) School would share the mysticism since it was under the influences of Gong-yang School until Later Han period. Unlike Gong-yang School, however, rationalism has been found in Zuo-zhuan School. To prove the rationalistic view of nature in Zuo-zhuan School, this article analyzed Chun-qiu Zuo-shi Zhuan Jie-yi written by Fu-qian. Fu-qian proposed a new interpretation of Zai-yi and tried to establish the theory of mutual influence between Tian(天) and human beings. Fu-qian’s view of nature did not rely on the existence of Tian or Shen(神) as a personified supervisor, nor espouse arbitrary prophecies. The focus was on a moral nature. Fu-qian attempted to clarify the cosmic order using the theory of Xiangshu Xue(象數學). With these achievements, Fu-qian’s Annotation on Zuo-zhuan began to spread in Wei-Chin-Nan-Pei-Chao(魏晋南北朝) period. The trigger was the learning of the classics in ancient form of the Chinese character(Gu-wen Xue, 古文學). This tendency had changed the study style from Jin-wen Xue(今文學) to Gu-wen Xue. In these process, Fu-qian’s view might be enabled to widespread.

We report a case with squamous cell lung cancer with concomitant Guillain-Barre syndrome (GBS) as a paraneoplastic syndrome. A 67-year-old patient who was previously diagnosed as metastatic squamous cell lung cancer developed mild symmetrical weakness, paresthesia and sensory ataxia. Nerve conduction study showed sensorimotor polyneuropathy. Analysis of cerebrospinal fluid showed high tilter for monospecific anti-GD1b IgG antibody without onconeuronal antibodies. After treatment with intravenous immunoglobulin, the patient’s symptoms improved. (Korean J Clin Neurophysiol 2015;17:31-34)

[논문]서울 지역에서 인체 위해도에 입각한 대기오염물질의 관리 우선 순위 선정에 관한 연구

김예신,박화성,이용진,임영욱,신동천 한국대기환경학회 2003 한국대기환경학회지 Vol.19 No.2

We have gathered exposure data on ambient air quality level and investigated dose-response slope factors of air pollutants such as fine particle, HAPs(metals. VOCs, PAHs) and dioxims in Seoul. Theoretical mortality incidences were estimated from exposure to these pollutants. From the results, priorities were ranked in the order fine particle. metals, VOCs, dioxins and PAHs by ordinal scale, and the uncertainties relative to those risk estimates were described.

서울 대기 중 미세 먼지 노출로 인한 위해도에 근거한 우선 관리 지역 선정 : 이론적 사망 위해도 및 손실비용을 근거로

김예신,이용진,신동천 한국환경독성학회 2004 환경독성보건학회지 Vol.19 No.1

It is important to select a risk based priority area for environmental policy formation and decision-making. We estimated the health risks and associated damage costs from exposure to fine particles and assigned priority areas for twenty-five districts in Seoul. In order to estimate the theoretical mortality incidence of the health risk, baseline risks were estimated from mortality rates in two low level areas of fine particles, Seocho Gu and Cheju city. To estimate the damage cost from the risk estimates, we investigated and estimated the willingness to pay(WTP) for specific risk reduction. We assumed two different locations as the reference area, Cheju city as Scenario I and Seocho gu as Scenariao Ⅱ. From the results, the five districts, Kwangjin, Chungnang, Kangbuk, Nowon, and Kangnam, ranked high in the categories of both health risk and economic risk. Damage costs were over twenty billion won in each of these districts. As there are uncertainties in these results, the parameter values such as PM_(2.5) level, dose-response slope factor, baseline risk, exposure population and WTP should be continuously validated and refined.

환경 오염으로 인한 인체 위해도에 입각한 사망 손실 비용 추정에 관한 연구

Objectives : To estimate the value of statistical life (VSL) and health damage cost on theoretical mortality estimates due to environmental pollution. Methods : We assessed the health risk on three environmental problems and eight sub-problems. Willingness to pay (WTP) was elucidated from a questionnaire survey with dichotomous contingent valuation method and VSL (which is the division of WTP by the change of risk reduction) calculated from WTP. Damage costs were estimated by multiplying VSL by the theoretical mortality estimates. Results : VSLs from death caused by air pollution, indoor air pollution and drinking water contamination were about 0.3, 0.5 and 0.3 billion won, respectively. Damage costs of particulate matters ($PM_{10}$) and radon were higher in the sub-problems and were above 100 billion won. Because damage cost depends on theoretical mortality estimate and WTP, its uncertainty is reduced in the estimating process. Conclusion : Health damage cost or risk benefit should be considered as one scientific criterion for decision making in environmental policy.

Research on the effect of sports activities for adolescents

김예신,이근춘 충북대학교 국가미래기술경영연구소 2019 기술경영 Vol.4 No.3

The purpose of this study is to examine whether extracurricular sports activities are associated with children’s behavioral problems. This study utilized data from Panel Study of Income Dynamics (PSID) and the 2014-Child Development Supplement (CDS) on children in the U.S. who were 6-16 years old. This study found that given a significant difference in parental and familial socioeconomic status between parents in single-parent families and parents in two-parent families, children of single-parent families spent less time in structured activities compared to those of two-parent families. Children in two-parent families spent a weekly average of 3.03 hours on sports activities, while children in single-parent families spent a weekly average of 2.01 hours on sports activities. In addition, an increase in time spent on sports activities decreased children’s internalizing behavioral problems in single-parent families. This study indicates that the availability and affordability of parents are important factors for children in participating in structured extracurricular activities. Extracurricular sports activities play a protective role for children of single-parent families through supervision from adults. Furthermore, not participating in sports activities may lead children to participate in unstructured activities, which could increase both internalizing and externalizing behavioral problems. This study implicates that a more affordable and available policy on sports activities for children in single-parent families could further decrease their behavioral problems.

To estimate the annual WTP for risk reduction of environmental problems such as outdoor and indoor air pollution, and drinking water contamination, a questionnaire survey was conducted by dichotomous contingent valuation method in Seoul. Several covariate models based on Turnbull, Weibull and Spike models were developed and applied to WTP estimation with uncertainty analysis. WTP estimates for risk reduction of air pollution were 13,000 won, 12,000 won, and 10,000 won per month in low-bounded Turnbull, Weibull and Spike models, respectively. The estimates for indoor air pollution were 17,000 won, 20,000 won and 21,000 won and these for drinking water contamination were 10,000 won, 13,000 won and 14,000 won in each model, respectively. Goodness of fit for Weibull model was better than those for other models. WTP estimates for indoor air pollution were higher than those for other pollution problems.
