Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

자연환경방사선의 세 가지 주요 요소인 지각방사선, 우주선 전리성분 및 라돈과 그 자핵종이 주는 선량을 측정, 해석하였는 바 18개월간에 걸쳐 대전, 수원, 경산 지역에 대하여 수행하고 이를 종합하여 유효선량당량으로 평가하였다. 지각방사선과 우주선 전리성분 측정을 위하여 3"∮×3" Nal(Tl) 섬광검출기와 휴대형 다중파고분석기를 이용한 감마선 분광분석 및 ^7LiF PTEE disk TLD에 의한 적산선량측정을 병행하였고, 공기중 라돈농도의 측정은 CR-39 고체비적검출기를 내장한 라돈컵을 설계제작하여 사용하였으며 비적수 라돈농도 교정인자는 스웨덴 국립방사선 방호연구소의 표준 라돈 챔버내에서 조사하여 결정하였다. 세 지역의 가연방사선에 의한 유효선량당량에는 약간의 수치적 차이는 있었으나 본질적 차이는 찾아볼 수 없었으며 지역 측정치의 분산가중 평균치는 지각방사선 (463±3)uSvㆍy^-1[(52.9±0.3)nSvㆍh^-1], 우주선 전리성분 (287±15)uSvㆍy^-1[(32.8±1.7)nSvㆍy^-1]로 외부 피폭이 (775±9)uSvㆍy^-1[(88.5±1.0)nSvㆍy^-1]였으며 라돈과 그 자핵종에 의한 내부피폭은 (1973±298)uSvㆍy^-1[(225.2±34.0)nSvㆍy^-1]였다. 따라서 자연황경방사선에 의한 여간 총 선량당량은 (2762±296)uSvㆍy^-1[(315.3±34.0)nSvㆍh^-1]로 평가되었는데 이 값들은 UN보고서^(11)에 나온 “정상적 자연방사선 지역”의 값과 비교할 만한 타당한 값으로 나타났다. Assessment of effective dose equivalent from natural environmental radiation that consists of terrestrial gamma­ray, ionizing component of cosmic­ray and alpha­rays of atmospheric radon and its decay products has been carried out for 18 months in Daejeon, Suwon and Kyungsan areas. A 3"∮×3"cylindrical Nal(Ti) scintillation detector in association with portable multichannel analyser and ^7LiF PTFE disk TLDs were used for the measurement of terrestrial gamma­ray and cosmic­ray ionizing component, while self­designed radon­cups with CR-39 SSNTD attached to the inside bottom were used for the integral measurement of at­mospheric radon concentration. Determination of calibration factor for converting track density of CR-39 detector to radon concentration was made by irradiation of radon­cups in the standard radon chamber of Swedish National Institute of Radiation Protection. Although resultant effective dose equivalents of three different measurment points show minor numerical differences, no essential discripancy between the places was found. The variance weighted means of the annual effective dose equivalents of each component of radiation from the tree places came out to be: (463±3)uSvㆍy^-1[(52.9±0.3)nSvㆍy^-1] for terrestrial gamma­ray, (287±15)uSvㆍy^-1[(32.8±1.7)nSvㆍy^-1] for ionizing component of cosmic­ray and (1973±298)uSvㆍy^-1[(225.2±34.0)nSvㆍy^-1] for internal exposure of radon and its decay products. Consequent total effective dose equivalent turned out to be (2762±298)uSvㆍy^-1[(315.3±34.0)nSvㆍy^-1], which if reasonably comparable with that appeared in UNSCEAR Report^[11]as per caput annual effective dose equivalent in “areas of normal back ground radiation.”

Multifunctional Amine-Containing PVA-<i>g</i>-POEM Graft Copolymer Membranes for CO₂ Capture

Kim, Do Hyun,Park, Min Su,Kim, Na Un,Ryu, Du Yeol,Kim, Jong Hak American Chemical Society 2018 Macromolecules Vol.51 No.15

<P>CO<SUB>2</SUB> separation technology using polymeric membranes has emerged as a viable solution to mitigate the rapidly increasing anthropogenic CO<SUB>2</SUB> emissions, which are directly linked to global warming and climate anomalies. However, in order to improve the gas separation performance, an intrinsic problem of polymeric membranes, i.e., a trade-off relationship between permeability and selectivity, needs to be addressed. In this study, a solid-state facilitated transport membrane is prepared by blending CO<SUB>2</SUB>-philic, amine-compatible poly(vinyl alcohol)-<I>g</I>-poly(oxyethylene methacrylate) (PVA-<I>g</I>-POEM) graft copolymer and diethylenetriamine (DETA) carriers. The graft copolymer consisting of PVA main chains and POEM side chains is synthesized via one-pot free radical polymerization and used as a polymer matrix. With the incorporation of 10 wt % of DETA into the polymer, the membrane exhibits a high CO<SUB>2</SUB> permeance of 402.5 GPU (1 GPU = 10<SUP>-6</SUP> cm<SUP>3</SUP>(STP)/(s·cm<SUP>2</SUP>·cmHg)) and CO<SUB>2</SUB>/N<SUB>2</SUB> selectivity of 52.1. The enhanced performance of the membrane results from multifunctional amine carriers in the graft copolymer owing to facilitated transport of CO<SUB>2</SUB> and an increase in the crystallinity of the polymer. DETA acts as a seed for crystallization of PVA chains at a low loading, which leads to a reduced N<SUB>2</SUB> permeance. The membrane exhibits good stability without any performance degradation over 2 weeks in the solid state. The superior separation property of the PVA-<I>g</I>-POEM membrane containing DETA distinguishes this facilitated transport membrane from other similar membranes and commercial membranes.</P> [FIG OMISSION]</BR>

Non-Hodgkin's lymphoma (NHL) is the secondary most common tumor in HIV-infected individuals. The AIDS-related lymphomas are a late manifestation of HIV infection and may increase in frequency as patients live longer with highly active antiretroviral therapy and effective prophylaxis of opportunistic infections. Histologically AIDS-related NHL are either high (2/3) or intermediate (1/3) grade lymphoma. We report a case of gastric Non-Hodgkin's lymphoma in AIDS patient. Two years ago, she was diagnosed as HIV-infected individual in public hospital. She presented with epigastric pain and mass-like sensation. Under the impression of gastric cancer, subtotal gastrectomy was done. But, she diagnosed as diffuse large B cell lymphoma by histologic finding, immunohistochemical study. This is the first report of gastric Non-Hodgkin's lymphoma from AIDS patients in Korea(Korean J Med 62:223-229, 2002)

폐광지역의 침하발생 메커니즘 및 영향범위는 현장의 지반조건, 지압분포, 채굴적의 기하학적인 조건, 상부 구조물의 하중 조건 등에 따라 달라지므로 이를 예측하기는 매우 어렵다. 또한 지질 및 지반 상태, 탄층의 발달 상태, 채굴방법 등이 채굴현장마다 다르므로 기존의 보강대책을 그대로 적용하는 데에는 한계가 있다. 본 연구에서는 국내 폐광지역에 대한 합리적인 보강대책 수립을 위해 광역 채굴현황조사를 바탕으로 채굴적의 분포를 파악하고, 대심도 시추조사, 탄성파 토모그래피, 시추공 영상촬영 등의 상세 지반조사를 수행하여 석탄층의 분포현황과 암반이완상태를 파악하였다. 이를 토대로 지반침하이론에 의해 침하발생 유형을 예측하고 지반침하량을 산정하였다. 또한, 연구대상 지역의 침하발생 메커니즘을 분석하였으며, 기존 폐광지역 보강사례를 분석하여 각 침하원인별로 대상지역의 지반특성에 부합되는 지반 및 구조물기초에 대한 보강대책을 수립하였다. As the mechanism and effect range of subsidence are altered according to the various conditions (the ground condition, the earth pressure, the geometric condition of underground cavity and the structure load), the analysis and prediction of subsidence in abandoned mining area are very difficult. Also, as the geological characteristics and the mining methods are differed in each mines, the application of the pre-existing reinforcements without improvement has a lot of difficulties and limits. In this study, the various underground investigation such as longdepth core drilling, seismic tomography and BIPS (borehole image processing system) were performed, the distribution of underground cavity and coal seam and rock relaxation condition were analyzed. And we predicted the type of subsidence and estimated the subsidence by theories of mining subsidence. With these results, we analyzed the mechanism of subsidence occurrence in the research object area. Finally, we improved existing methods which were applied to the abandoned mining area and also we established the rational reinforcement for the ground and structure foundation against each subsidence cause.
