Burning acupuncture is one of the methods of curing and preventing many kinds of diseases by inserting and taking out of the needle into particular points of the body so called acupuncture points, using a heated Dae-Chim which is one of the nine kinds of needles used in ancient times or by inserting a thick needle after its been heated to certain temperature. Nowadays in China, Burning Acupuncture is used thoroughly from musculoskeletal diseases to, internal medicine, gynecology and many other clinical departments. But in Korea, this method of cure is practiced by only a few clinicians, therefore by studying historical documents, our object is to recognize the importance of the Burning acupuncture and to offer the basis for the scientific researches and clinical application.

실내,외 통합 모델링 및 인체 위해성 평가를 통한 실내 유해화학물질의 관리 전략

신용승 ( Yong Seung Shin ),임혜숙 ( Hye Sook Lim ) 한국환경정책평가연구원 2008 환경정책연구 Vol.7 No.2

본 연구의 목적은 실내 공기내의 유해화학물질의 농도 수준에 영향을 줄 수 있는 요소들을 통합적으로 고려하여 실내 공기질의 관리 전략을 수립하는 것이다. 이러한 목적으로 서울대에서는 실내 공기내의 유해화학물질의 농도 예측을 위한 ‘통합적 실내 공기질 모델(IIAQ)’을 개발한 바 있다. 본 연구에서는 IIAQ모델을 사용하여 실내 공기내 유해화학물질의 농도를 도출하고 이 결과를 바탕으로 연구에서 제시된 시나리오에 따른 인체 위해성 평가를 수행하였다. IIAQ 모델을 통해 예측된 톨루엔과 포름알데히드의 10년 평균 농도는 실내에서 207.3 ug/m3, 36.4ug/m3, 실외에서의 측정값은 55.9 ug/m3, 8.62 ug/m3 으로 현재 실내 공기질 기준에 이하인 것으로 나타났다. 그러나 위해성 평가 결과, 포름알데히드의 노출로 인해서 예상 가능한 발암 위해도가 성인 남성 그룹에서 최대 1.05E-03인 것으로 나타났으며, 모든 수용체 그룹에서 자연적인 암 발생률인 1E-06을 초과하는 것으로 나타났다. 반면, 톨루엔에 대한 비발암 위해도는 모든 수용체 그룹에 대해서 1보다 작은 것으로 나타나, 심각하게 우려할 만한 비 발암 위해성이 나타날 가능성은 낮은 것으로 생각된다. 한편 본 연구에서 수행된 신축 공동주택에서 신축 후 10년간의 관심 화학물질인 톨루엔 및 포름알데히드에 농도 변화에 대한 모델링 결과 실내 오염원이 실외 오염원에 비해 실내 공기 오염에 더 큰 비중을 차지하는 것으로 나타나, 유해물질 위해도를 저감하기 위해서는 우선적으로 주요 실내 공기 오염원을 감소시킬 수 있는 전략이 수립되어야 할 필요가 있는 것으로 생각된다. 그리고 위해성 평가 결과는 현재의 실내 공기오염 기준치에 준하게 노출되었을 경우에 발암 위해성이 있을 수 있으므로, 현재의 실내 공기오염 기준치는 실내·외 오염원으로부터의 모든 노출 경로에 대한 총 노출량을 감안하여 총 노출 및 위해성을 감소시킬 수 있는 적절한 기준치로 재정립 되어야 할 필요가 있는 것으로 생각된다. The purpose of this study is to develop indoor air quality management strategies regarding indoor air pollutants while considering various factors affecting indoor pollutants concentration. The Integrated Indoor Air Quality model (IIAQ) developed by Seoul National University is used for this study. The IIAQ model is a tool that can provide an integrated view to indoor environmental pollution by simulating suggested scenarios. The results of the modeling are used to assess health risk. The concentrations that are used for the risk characterization are weighted concentrations based on the period of time in each place and existing Indoor Air Quality (IAQ) standards. The estimated concentration of toluene and formaldehyde for 10 years through the IIAQ model was 207.3 ug/m3 and 36.4 ug/m3 in indoors, and 55.9 ug/m3 and 8.62 ug/m3 in outdoors. These concentrations are lower than the existing IAQ standards. The estimated carcinogenic risk of formaldehyde is up to 1.05E-03 for the adult male group and exceeds 1E-06 for all receptor groups. This value means that cancer could affect one person out of 1000. The estimated non-carcinogenic risk of toluene was lower than 1, which means that there was no serious non- carcinogenic risk. The result of modeling shows that using low emitting indoor sources is the most effective strategy for both formaldehyde and toluene. This risk assessment suggests that the total exposure levels of existing IAQ standards may cause serious carcinogenic risk. In order to avoid uncontrolled risk, it is suggested that the current IAQ standards should be adjusted by taking into account the total amount of exposure from all exposure pathways from indoor and outdoor sources.

통합환경관리를 위한 매체 통합적 위해성 평가의 필요성 및 현황

신용승(Shin yong-seung) 강원대학교 비교법학연구소 2009 환경법과 정책 Vol.2 No.-

The environment is comprised of various multi-media including air, water, soil and so on. Numerous kinds of hazardous chemicals are increasingly emitted into the environment from various emission sources, which makes it more complexand difficult to resolve the environmental problems. Since hazardous chemicals behave interactively in the multi-media environment by being transferred and/or partitioned from one medium to another, it requires so-called 'multi-media approach' to assess their fate in the environment and to develop appropriate policy measures. Medium-specific environmental management of hazardous substances may result in the failure of environmental policies. Currently, 'integrated environmental management' has become a new paradigm for the management of hazardous chemicals in many countries. Furthermore, receptor-oriented risk assesment and management is currently pursued as one of tools for the integrated environmental management. In receptor-oriented approaches, decision is made based on the total risk arising from multi-exposure pathways, which may be called 'Integrated Multimedia Risk Assessment' and compared to aggregated and/or cumulative risk assessment as carried out in the united states or EU countries. In this paper, basic concepts and policy needs for integrated multimedia risk assessment are introduced and current status in Korea and other countries including united states and EU is reviewed. Ministry of Environment Korea emphasizes the importance of integrated risk assessment and management of hazardous substances and gives efforts to construct technical and instrumental infra-structures for implementing such policy initiatives. In Korea, it is expected that the integrated environmental management will come true in near future as being supported by integrated multimedia risk assessment.

Background: With volatile organic compounds (VOCs) containing aromatic and halogenated hydrocarbons such as benzene, toluene, and xylene that can adversely affect the respiratory and cardiovascular systems when a certain concentration is reached, it is important to accurately evaluate the source and the corresponding health risk effects. Objectives: The purpose of this study is to provide scientific evidence for the city of Seoul’s VOC reduction measures by confirming the risk of each VOC emission source. Methods: In 2020, 56 VOCs were measured and analyzed at one-hour intervals using an online flame ionization detector system (GC-FID) at two measuring stations in Seoul (Gangseo: GS, Bukhansan: BHS). The dominant emission source was identified using the Positive Matrix Factorization (PMF) model, and health risk assessment was performed on the main components of VOCs related to the emission source. Results: Gasoline vapor and vehicle combustion gas are the main sources of emissions in GS, a residential area in the city center, and the main sources are solvent usage and aged VOCs in BHS, a greenbelt area. The risk index ranged from 0.01 to 0.02, which is lower than the standard of 1 for both GS and BHS, and was an acceptable level of 5.71×10-7 to 2.58×10-6 for carcinogenic risk. Conclusions: In order to reduce the level of carcinogenic risk to an acceptable safe level, it is necessary to improve and reduce the emission sources of vehicle combustion and solvent usage, and eco-car policies are judged to contribute to the reduction of combustion gas as well as providing a response to climate change.

충청,전라지역 산업단지 주변지역에서의 벤젠 인체 위해성 평가

장용철 ( Yong Chul Jang ),이성우 ( Sung Woo Lee ),신용승 ( Yong Seung Shin ),김희갑 ( Hee Kap Kim ),이종현 ( Jong Hyun Lee ) 한국환경영향평가학회 2011 환경영향평가 Vol.20 No.4

This research studied human health risk assessment of benzene from industrial complexes of Chungcheong Province (Seosan industrial complex) and Jeonla Province (Iksan industrial complex and Yeosoo industrial complex). The residents near the industrial complexes areas can be often exposed to volatile organic compounds (e.g., benzene, toluene, xylenes) through a number of exposure pathways, including inhalation of the organic pollutant via various environmental matrices (air, water and soil), contaminated water, and soil intake. Benzene is well known to be a common carcinogenic and toxic compound that is produced from industrial and oil refinery complexes. In this study, a number of samples from water, air, and soil were taken from the residential settings and public school zones located near the industrial complex sites. Based on the carcinogenic risk assessment, the risk estimates were slightly above 1.0×10(-6) at all three industrial sites. According to deterministic risk assessment, inhalation was the most important route. The distribution of benzene in the environment would be dependent on vapor pressure, and the physical property influencing the extent of the potential risks. Noncarcinogenic risk assessment of benzene shows that the values of Hazard Index(HI) were much lower than 1.0 at all industrial complexes. Therefore, benzene was not a cause of concern in terms of non-carcinogenic risk posed to the residents near the sites. When compared to probabilistic risk assessment, the CTE(central tendency exposure) cancer risk values of deterministic risk assessment were close to the mean values predicted by the probabilistic risk assessment. The RME(reasonable maximum exposure) values fell within the range of 95% to 99.9% estimated by the probabilistic risk assessment. Since the values of carcinogenic risk assessment were higher than 1.0×10(-6), further detailed monitoring and refined risk assessment for benzene may be warranted to estimate more reliable and potential inhalation risks to receptors near the industrial complexes.

Olive flounder (Paralichthys olivaceus) is the major mariculture fish in Korea. The annual aquaculture production of olive flounder in Korea during the period of 2003 was 300,000 ton (2002 Statistics, Ministry of Maritime Affairs & Fisheries, Korea Government). Anesthetics is very necessary in aquaculture to minimize stress and damage during harvesting, grading, transportation, spawning induction and handling to fish. In the present study, isoeugenol as new anesthetic in marine fish, especially olive flounder, was examined to know the efficacy and proper concentration. As a result, olive flounder adult was exhibited sedation at 5 ppm at 10 and $15^{\circ}C$, and 7.5 ppm at $20^{\circ}C$, respectively. Anesthesia was required at least 10, 7.5 and 10 ppm at $10^{\circ}C$, $15^{\circ}C$ and at $20^{\circ}C$, respectively. In case of fry, the effect of sedation was observed from 2.5 ppm at $10^{\circ}C$ and 5 ppm at 15 and $20^{\circ}C$, respectively. Anesthesia was observed from 2.5 ppm at $10^{\circ}C$, 5 ppm at 15 and $20^{\circ}C$, respectively. In acute toxicity test, it was impossible to explore $LD_{50}$ with the concentration of isoeugenol adult at $15^{\circ}C$ used, but over immersion volume of 15 ppm at $15^{\circ}C$ was observed mortality in fry. Based on the present study, isoeugenol was identified as a safe and active anesthetic to olive flounder.
