Abundance and diversity of arthropods were projected according to climate warming in South Korea. The taxa highly linked with temperature were selected for the projection. The values of abundance and richness were estimated using the mean values of abundance and richness in each temperature range. Temperature changes were based on the RCP (Representative Concentration Pathway) 4.5 and RCP 8.5, and the abundance and richness during two periods (2011 -2015, 2056 -2065) were projected. From these projected results, change of other common taxa (> 1% occurrence) were qualitatively predicted (i.e., decrease or increase). The projections showed that 45 of a total of 73 taxa will increase, 6 will change a little and 24 will decrease: the number of taxa that were expected to increase was two times more than the number of taxa that were expected to decrease. However, the overall abundance and diversity of arthropods were expected to decline as the temperature rises.

전자담배와 가열담배의 국제적 규제정책 비교

이철민 대한의사협회 2020 대한의사협회지 Vol.63 No.2

This document provides a description of country-level laws that regulate electronic cigarettes and heated tobacco products. The mechanisms used to regulate e-cigarettes were classified as either new/amended laws or existing laws. The policy domains identified include restrictions or prohibitions related to the product (sale, manufacturing, importation, distribution, use, product design including e-liquid ingredients, advertising/ promotion/ sponsorship, and trademarks) and regulatory requirements (taxation, health warning labels, and child-safety standards). A range of regulatory approaches are currently being applied to e-cigarettes globally; however, many countries still regulate e-cigarettes using legislation not tailored specifically for e-cigarettes. Only a handful of countries levy a tax on e-cigarettes. Evidence on the harmful effects and benefits of e-cigarettes usage has not been clearly established yet. The regulatory treatment of heated tobacco products varies from country to country, with some classifying e-cigarettes and cigarettes under the same legislation, other countries treating e-cigarettes more favorably, and some jurisdictions banning them altogether. As the evidence base grows, we expect additional activity in the regulatory arena.

이철민,김윤신,이태형,김종철,김중호,Lee , Cheol-MIn,Kim , Yoon-Shin,Lee , Tae-Hyung,Kim , Jong-Cheol,Kim , Jung-Ho 한국환경보건학회 2004 한국환경보건학회지 Vol.30 No.3

We estimated decreasing rate of indoor air pollutants which are PM10 and $NO_2$ by the air cleaner in indoor environment. This study respectively examined concentration of PM10 and $NO_2$ two times in 34 sites located in Seoul and Kyung-gi Do from April to September in 2003. Sectional period was respectively divided for operating the air cleaner and non-operating the air cleaner. Moreover, questionnaire was executed to grasp physical characteristic of objective building and residential characteristic of residents by using method of self-entry. There was a trend that concentration of PM10 and $NO_2$ separated number of residents during operating period respectively decreased among indoor air. According to the existence of smoker in indoor, both concentration of PM10 and $NO_2$ during operating period decreased in each case, and according to existence of pets, both cases decreased concentration of pollutants by operating the air cleaner. We used Monte-Calro simulation to remove uncertainty and identify efficiency of eliminated pollutants such as PM10 and $NO_2$ by the air cleaner. Average efficiency of removal for PM10 and $NO_2$ were 61.84${\pm}$23.04% and 48.67${\pm}$18.03% respectively.

이철민,박화미,노영만,김윤신,박동선,Lee, Choel-Min,Park, Wha-Me,Roh, Young-Man,Kim, Yoon-Shin,Park, Dong-Sun 한국환경보건학회 2008 한국환경보건학회지 Vol.34 No.1

The objective of this study is to provide the research data on the actual concentrations of $PM_{10},\;PM_{2.5},\;PM_1\;and\;CO_2$ in Seoul subway carriages. Mean concentrations of $PM_{10},\;PM_{2.5}\;and\;PM_1,\;and\;CO_2$ in subway carriages were investigated at levels of $215.1{\pm}101.4{\mu}g/m^3,\;86.9{\pm}38.6{\mu}g/m^3,\;27.0{\pm}11.4{\mu}g/m^3,\;and\;1,588{\pm}714ppm$, respectively. The mean concentrations in subway carriages were higher when the train ran on an underground track rather than on an above ground track. The measured concentration of particulate matter varied with the time of day and was highest in the morning, followed by noon and evening while the $CO_2$ concentration was highest in the morning, followed by evening and noon. In relation to correlation among the pollutants: the correlation between $PM_{10}\;and\;PM_{2.5}$ was 0.92, and that between $PM_{2.5}\;and\;PM_1$ was 0.94. The inclusion rate of $PM_{2.5}\;to\;PM_{10}$ was $41{\pm}7%$ and that of $PM_1\;to\;PM_{2.5}\;was\;32{\pm}4%$. In addition, the $CO_2$ concentration had a positive relation with the number of people in a carriage, whereas the concentration of $PM_{10}$ had negative correlation to the number of people. In relation to these two pollutants we calculated using a regression equation (34.06+0.04$CO_2$(ppm)-0.09 PM10$({\mu}g/m^3)$($R^2$=0.30, p<0.01, n=707), that a maximum number of 61 persons would ensure that each pollutant is maintained below the criteria level, applicable to subway stations.

본 연구는 개벌 후 나비군집의 변화를 파악하기 위해서 실시하였다. 조사는 2011년 개벌지, 임도, 산림에서 5월부터 11월까지 선조사법을 실시했다. 조사결과, 총 32종 398개체의 나비가 관찰되었다. 먹이생태지위 범위와 서식처 유형에서의 나비 개체수는 개벌지가 산림보다 유의하게 높았다. 나비의 종수와 종다양도는 개벌지가 산림에 비하여 유의하게 높았다. 개벌지에서 환경부 취약종 기생나비와 은점표범나비의 많은 개체가 확인되었다. 본 연구결과, 개벌로 인하여 형성된 초지는 산림생태계에서 나비의 다양성을 높이는 중요한 역할을 한다. This study was carried out to clarify the change of butterfly community after clear cutting. Butterfly survey was conducted in clear cutting area, forest road, and forest using line transect method from May to November in 2011. A total of 32 species and 398 individuals of butterflies were observed. Abundance of food niche breadth and habitat type was significantly higher in clear cutting area than in forest. Estimated species richness and species diversity were significantly higher in clear cutting area than in forest. In clear cutting area, Leptidea amurensis and Argynnis niobe, vulnerable species, were abundant. This result suggests that grasslands formed by clear cutting play an important role to increase butterfly diversity in forest ecosystem.

이철민,신연명,Lee, Chul-Min,Shin, Yeon-Myung 대한위암학회 2008 대한위암학회지 Vol.8 No.4

목적: 위에 발생하는 신경내분비 종양은 국내에서도 그 보고가 드문 매우 독특한 조직형인데, 이 종양의 임상병리학적 특징들에 대해 알아보고자 하였다. 대상 및 방법: 1999년 1월부터 2007년 8월까지 고신대학교 의과대학 외과학교실에서 위암으로 수술받은 4,159예 중 신경내분비 종양으로 진단받은 13예를 대상으로 의무기록 및 조직 표본을 후향적으로 분석하였다. 결과: 위 신경내분비 종양은 남자 11예, 여자 2예였고, 평균나이는 54.9세(42~72)였으며, 주증상은 상복부 통증과 속쓰림이 많았다. 점막 또는 점막하 종양 2예를 제외하고 나머지 9예는 모두 근육층 이상을 침범한 진행성이었고, 종양의 평균 크기는 7.0 cm (0.7~15)였다. WHO 분류법에 의한 내분비 종양의 유형은 제 3형이 8예, 제 4형이 4예, 제 1형이 1예였다. 림프절 전이는 11예에서 있었고, 추적 기간내 재발한 4명의 환자 모두 제 3형과 제 4형이었고, 재발한 장기는 간이 2예, 다장기(복막, 폐) 1예, 다장기(간, 췌장, 십이지장) 1예였고, 생존 기간은 평균 12.8개월이었다. 결론: 위에 발생하는 신경내분비 종양은 진단 당시 진행된 경우가 많았고 간 전이를 잘 하였으며 예후가 나쁜 독특한 조직형이다. Purpose: The goal of this study was to review the clinicopathologic characteristics of neuroendocrine tumor (NET) of the stomach. Materials and Methods: We retrospectively reviewed the medical records of 13 patients who were diagnosed with neuroendocrine tumor from January 1999 to August 2007 at Kosin Medical Center; 4,159 gastric cancer patients were treated surgically during the same time. The average follow up period was 14.3 months. Results: The majority of 13 patients were men (male-female ratio: 11:2) and the average age of patients with NET was 59.4 years (range: 42~72 years). The presenting symptoms were mostly epigastric pain and soreness. The tumor was limited to the mucosa or submucosa in two cases, and the tumor extended beyond the muscle layer in 11 cases. The mean size of the tumor was 7.0 cm, ranging from 0.7 cm to 15 cm. The type of the NEC (according to the WHO classification) was type 3 for eight patients, type 4 for four patients and type 1 for one patient. Regional lymph node metastasis was noted in 11 patients. Four cases showed recurrence of disease and the site of recurrence included liver in two patients, multiple organs (including the peritoneum and lung) in one patient and multiple organs (including liver, pancreas and duodenum) in one patient. The recurrent cases were type 3 and type 4 and the average survival period of the recurrent patients was 12.8 months. Conclusion: The majority of neuroendocrine tumors of the stomach were at an advanced stage at the time of diagnosis. These tumors frequently recurred in the liver and they have a poor prognosis.
