스트레칭(stretching)은 최근 신체 각 부위를 적절하게 움직이게 하여 긴장과 피로를 풀어주어 신체 발달을 꾀하고 유연성을 향상시키는데 좋은 운동방법으로 평가되고 있다. 온열요법(heating therapy)은 신체부분에 국소적으로 열을 가하여 혈액의 순환을 증가시켜서 손상의 빠른 회복을 기대하여 물리치료학에서 현재 많이 이용되는 방법으로 관절 경직의 완화, 동통 완화, 그리고 근 경련의 감소에 효과적이다. 본 연구에서는 20대에서 40대 사이의 신경학적 제한이 없는 정상인을 대상으로, 스트레칭 운동을 시행할 때 혼합되는 온열요법이 요부의 유연성 개선에 미치는 효과를 알아보고자 하였다. 20대에서 40대 20명(남10, 여10명)을 10명씩 두 집단으로 나누어 한 집단은 8 동작의 스트레칭 시행하는 스트레칭 집단으로 하고, 다른 한 집단은 온습포(hot pack)와 8 동작의 스트레칭을 혼합하는 열-스트레칭 혼합 집단으로 하였다. 각 집단은 주 4회 6주간 실시되었으며, 유연성 검사를 위해 체간 굴곡(trunk flexion), 체간 신전(trunk extension), 그리고 요부의 유연성을 나타내는 Schober-test를 측정하였다. 두 그룹간의 차이를 연구하여 요부의 유연성 개선에 미치는 효과를 검증하였으며, 나아가 본 연구는 요부 안정화 프로그램의 중요성과 산업체 근로자와 장시간 같은 자세로 작업을 하는 장애자들에게서 흔히 발생하는 요부의 통증에 접근하기 위해 고안되었다. The purpose of this study is to verify the difference of effect between group and period in order to find out effect on lumbar flexibility of treatment modality(stretching, heat - stretching) and period. The subject was chosen from the mild physically normal person who range from 20 to 40 years old without any neurological problem. Among these subjects, 20 persons(10 male, 10 female) were selected to two different groups. These were classified as stretching and heat- stretching groups. In stretching group, 8 different kind of stretching exercises were performed. In heat-stretching group, hot pack and stretching were performed together with 8 different stretching exercises. For the measurement of flexibility, trunk flexion test, trunk extension test and Schober-test were used. Pre-test was performed before treatment test, post-test was performed after 6 week of treatment test. As a result of this test, the following fact was shown 1) In trunk flexion and trunk extension test, effect between groups did not occur but effect of treatment period showed significance statistically. In addition, interactive effect between treatment period and each group showed the biggest difference in heat and stretching group. 2) In Schober-test, effect of treatment period showed significance statistically, effect between group and interactive effect did not occur.

It is well known that α- and β-antigens are major protein products of Mycobacterium tuberculosis. Alpha and beta antigens from the cell extract of Mycobacterium tuberculosis were purified by 80% ammonium sulfate precipitation, gel filtration of Sephacryl S-300, DEAE-Sephacel ion exchange chromatography and hydroxylapatite chromatography. Beta antigen was purified further by column preparative polyacrylamide gel electrophoresis. The purified alpha and beta antigens were checked degree of purified by SDS-polyacrylamide gel electrophoresis. The results were summarized as follows: 1. Alpha antigen was purified by ammonium sulfate precipitation, gel filtration, ion exchange chromatography and hydroxylapatite chromatography. The purified alpha antigen showed a distinct band of 30 KDa molecule on SDS-polyacrylamide gel electrophresis. 2. Beta antigen was purified by ammonium sulfate precipitation, gel filtration, ion-exchange chromatography, hydroxylapatite chromatography and column preparative polyacrylamide gel electophoresis. The purified beta antigen showed two distinct bands of 83 KDa and 52 KDa molecules on SDS-PAGE. 3. Especially, Beta antigen was absorbed well to hydroxylapatite column but alpha antigen was passed completely without absorption.

방사성폐기물 처리, 처분의 안정성 평가를 위하여 방사성 고화체에서 용출되는 137Cs과 90Sr의 방사능 용출율과 누적용출분율을 계측·분석하여 시멘트를 사용한 방사성 고화체에서 Cs+과 Sr++의 용출특성을 조사하였다. 모의방사성 폐액의 몰농도, 시멘트의 종류, 첨가물질 및 붕산농도 등을 변화시키면서 sodium silicate법과 중화법으로 원주형 시멘트 고화제를 제작하였다. 여기에서 가압경수로형 원자력 발전소의 모의 농축폐액의 시멘트 고화체로부터 용출연구는 IAEA의 추천방법에 따라서 수행되었다. 실험결과는 대부분 이미 보고된 연구자료들과 잘 일치하고 있으나 수밀성 시멘트 고화체에서는 상당히 높은 방사능 용출율을 보여주고 있음으로써 방사성 폐기를 고화체에 그 사용이 적합하지 않음을 알게 된다. For the safety assessment of radwaste treatment and disposal, the leaching characteristics of Cs++ and Sr++ from the cement-solidified radwastes was investigated by means of the survey and analysis of the activity leach rate and cumulative leach fraction of 137Cs and 90Sr leaching from solidified radwastes. The cylindrical cement-solidified samples were made by the sodium silicate method and neutralization method changing the mole density of simulated liquid radwaste, type of cement, adding material and concentration of boric acid. The leaching study was carried out by the method using simulated PWR concentrated liquid radwaste solidified in cement that had been processed following the recommendations of IAEA. All the experimental results are in well accordance with the research data reported previously, but the watertight cement-solidified radwastes show rather high leach rate of radioactivity. It is learned, therefore, that the watertight cement is not adequate as the material for the solidified radwastes.

Objectives : The Internalized Stigma of Mental Illness (ISMI) scale designed to measure the subjective experience of stigma with sub-scales measuring Alienation, Stereotype Endorsement. Perceived Discrimination, Stigma Resistance, and Social Withdrawal. The purpose of this study was to examine the reliability and validity of the Korean version of ISMI. Methods : The subjects were 194 schizophrenic patients and 205 peoples with depressive disorder. K-ISMI, CES-D (The Center for Epidemiologic Studies Depression Scale) and Self Esteem scale were performed. Results : Results showed that the ISMI had high internal consistence and split-half reliabilities. The internal consistency coefficients (Cronbach alpha) of each subscale ranged from .83 to .93. The validity of the ISMI was investigated by principal axis factoring analysis, yielding 5 factors of alienation, Perceived discrimination, negative stereotype, stigma resistance, devaluation and social withdrawal. 5 subscales explained 60.67% of total variance. Concurrent validity was supported by comparisons against scales measuring related constructs. As expected, the ISMI had positive correlations with CES-D, and it had negative correlation with self-esteem scale. Subsidiary analysis showed that schizophrenic patients showed higher internalized stigma than depressed patients. Conclusion : Overall, the findings support the utility of ISMl as a tool to evaluate internalized stigma of persons with mental illness. Interventions that can lessen internalized stigma may well hasten the recovery process in individuals with mental illness.

황지숙,송경식,김양섭,석순자,이태호,유익동 한국미생물생명공학회 ( 구 한국산업미생물학회 ) 1996 한국미생물·생명공학회지 Vol.24 No.5

담자균류로부터 지질과산화 저해물질을 탐색하던 중 강원도 오대산 지역에 자생하는 버섯의 한 종류로 부터, Sparague-Dawley계 rat의 간 mirosome 분획의 지질과산화를 강하게 억제하는 물질이 있음을 발견하였다. 이 버섯의 미생물학적 특성을 관찰한 결과 민주름버섯목, 굴뚝버섯과에 속하는 까치버섯(Polyzellus multiplex)으로 동정하였으며 본 버섯의 자실체 methanol 추출물을 benzene, ethylacetate로 순차적으로 추출하고 각종 chromatography를 이용하여 활성물질을 정제한 결과, ethylacetate층으로 부터 황산화활성을 나타내는 PM1을 benzene층으로 부터 지방산 계열의 PM2와 PM3 화합물을 순수하게 분리 정제하였다. PM1은 정색반응 및 각종 기기분석 결과 thelephoric acid계의 화합물로 동정되었으며 PM2 및 PM3는 각각 linoleic acid와 oleic acid로 동정되었다. 지질과산화 활성물질로 분리정제한 PM1 화합물의 IC_50 값은 1.96 ppm이었으며 LD_50 값은 500 mg/Kg 이상이었다. In the course of screening lipid peroxidation inhibitor from basidiomycetes, a mushroom, which was collected at O-Dae mountain in Kangweon-Do, was found to have active compound. The mushroom was identified as Polyzellus multiplex, which belongs to Aphylloporalles Thelephoraceae, on the basis of macroscopic and microscopic characteristics of the fruiting body. The methanol extract of fruiting body was extracted with benzene and ethylacetate, sequentially. By using various kinds of chromatographies, PM1, and PM2 and PM3, were purified from the ethylacetate extract and the benzene extract, respectively. Color reaction and analyses of IR, UV, and NMR spectra indicated that PM1 was a derivative of thelephoric acid, and PM2 and PM3 were linoleic acid and oleic acid, respectively. IC_50 of PM1 for inhibition of lipid peroxidation was 1.96 ppm and LD_50 was 500 mg/kg.

황원태,김은한,김병우,서경석,한문희 대한방사선 방어학회 1994 방사선방어학회지 Vol.19 No.3

원자력발전소의 중대 사고시 대기로 방출된 방사성물질에 의해 피폭자가 사고후 일생동안 받게 될 전신 피폭선량의 핵종의 상대적 중요도를 방출점으로부터 거리에 따라 각 피폭결로에 대해 평가하였다. 방사능운과 지표에 침적된 방사성물지에 의한 외부피폭,호흡과 오염된 음식물섭취에 의한 내부피폭이 피폭경로로 고려되었다. 오염된 음식물섭취에 의한 영향은 우리나라 환경을 고려하여 개발된 동적 섭식경로모델 KORFOOD를 사용하여 침적시점과 침점후 시간에 따른 음식물내 방사성물질의 농도 변화를 고려하였다. 방출점으로부터 80 km까지 피폭선량을 평가한 결과, 오염된 음식물섭취에 의한 영향이 가장 놓았다. 핵종별 기여도는 방사능운에 의한 외부피폭과 호흡에 의한 내부피폭의 경우 I, 침적된 방사성물질에 의한 외부피폭의 경우 Cs에 의한 영향이 가장 높았다. 오염된 음식물섭취에 의한 내부피폭의 경우 Cs은 여름철 침적, Sr은 겨울철 침적에 보다 중요한 영향을 미쳤다. In the case of a severe accident of a nuclear power plant, the whole body does and the relative importance of the radionuclides during the lifetime of an exposed person were estimated for each exposure pathway with distances from the release point. The external exposure pathways due to immersion of radioactive could and deposition of radioactive materials on the ground, and the internal exposure pathways due to inhalation and ingestion of contaminated foodstuffs were estimated considering the variation of radioactive concentration in the foodstuffs according to deposition time and elapsed time after deposition using a dynamic ingestion pathway model applicable to Korean environment, named "KORFOOD". As the results up to 80 km from the release point, the effects due to ingestion of contaminated foodstuffs showed the highest contribution to total exposure does. The contribution of I isotopes was the highest in the case of the external does due to immersion of radioactive cloud and internal does due to inhalation. The contribution of Cs isotopes was highest in the case of the external does due to deposition of radioactive materials on the ground. In the case of the internal does due to ingestion of contaminated foodstuffs, Cs deposition in summer and Sr deposition in winter, respectively, were the most dominant radionuclide to whole body.

원자력 사고 중 핵종의 건·습침적에 따른 농작물 오염 영향

황원태,김은한,서경석,한문희,최용호,이창우 대한방사선 방어학회 2002 방사선방어학회지 Vol.27 No.3

핵종의 지표 침적 모델의 고찰과 함께 방사성물질의 공기중 농도로부터 건침적 뿐 아니라 습침적에 따른 농작물 오염 영향을 분석, 고찰하였다. 이를 위해 방사성물질의 지표 침적량으로부터 농작물의 오염을 평가하는 기존 동적 섭식경로모델을 공기중 농도 또는 지표 침적량으로부터 평가할 수 있도록 개선하였다. 평가결과, 방사성물질의 지표 침적량은 습침적에 의한 영향이 건침적에 의한 영향보다 뚜렷이 높으나, 농작물의 오염정도는 핵종, 강우율 등에 따라 다르게 나타났다. 이러한 현상은 방사성물질의 지표 침적과 농작물에로의 차단중 어느 과정이 농작물 오염에 보다 지배적으로 작용하는가에 기인한다. Combined with deposition model onto the ground of radionuclides, the influence of radioactive contamination to agricultural products was analyzed due to wet deposition as well as dry deposition from radioactive air concentration during a nuclear emergency. The previous dynamic food chain model, in which initial input parameter is only radionuclide concentrations on the ground, was improved for the evaluating of radioactive contamination to agricultural products from either radionuclide concentrations in air or radionuclide concentrations on the ground. As the results, in case of deposition onto the ground, wet deposition was more dominant process than dry deposition. While the contamination levels of agricultural products were dependent on the a variety of factors such as radionuclides and rainfall rate. It means that the contamination levels of agricultural products are determined from which is more dominant process between deposition on the ground and interception onto agricultural plants.

구성태,조명수,황재호,변기원,김경식,손인철 한국전통의학연구소 2002 한국전통의학지 Vol.12 No.1

In the present study, we aimed. to consider the name of twelve main Meridian in order to understand the concept of the Meridian system and to applicate acupuncture theory in the clinical field properly and fundamentally. We referred to several literatures on the matter and we found out that the name of present twelve Meridian was not settled until the period of Yellow Emperor's Classic. In the time of Yellow Emperor's Classic, the two theory of Internal Organ and Meridian system were combined and added new theory of 'WoonGi'. The general rule of combination is that the component of name of Meridian consist of 'Hand' or 'Foot', 'three Eum and Yang' and internal organ. The internal organ coupled with the root ki or middle ki of 'three Eum and Yang' and the 'Hand' or 'Foot' depend on the location of internal organ that belongs to meridian. The name of Twelve Meridian is a kind of system formed to analyze the two concepts organically and dynamically. One is material internal organ and the other is immaterial meridian system.
