저자들은 정신분열병의 일부에서는 태생기 동안 유전 외적인 환경적 요인이 크게 작용할 것이라는 가정 하에 형제 정신분열병 환자군(남 15. 여 7)과 산발성 정신분열병 환자군(남 16, 여 7) 및 정상 대조군(남 16, 여 7)을 대상으로 가족력에 따른 산과적 합병증과 신체 미세 기형을 비교하였다. 산과적 합병증은 Lewis 척도를 이용하여 연구 대상의 어머니와 면담하여 평가하였고 신체미세기형은 Waldrop 척도를 이용하여 측정하였다. 또한 산과적 합병증 및 신체 미세기형과 가족력에에 따라 발병 연령 등의 임상 양상들이 차이를 보이는지 비교함으로써 정신분열병을 좀 더 동질적인 아형으로 나눌 수 있는지를 검토하였다. 1) 형제 환자군, 산발성 환자군 및 정상 대조군의 세균에서 산과적 합병증의 개개의 항목 및 전체 점수의 유의한 차이는 없었다. 신체 미세기형의 경우 입의 미세기 형에서 유의한 차이가 있었으나 그 외에 각 부위별 점수 및 전체 점수에서는 세 군간에 유의한 차이가 없었다. 그러나 대부분의 신체 미세기형 세부 항목 및 전체점수에서 산발성 환자군이 형제 환자군에 비해 높은 신체 미세기형의 점수를 보이는 경향이 있었다. 2) 산과적 합병증의 전체 점수와 신체 미세기형의 전체 점수 사이에 상호 연관성을 찾아볼 수 없었다. 3) 발병연령·정신병리·약물에 대한 반응·병전 기능수준·지연성 운동장애 유무 등의 임상 양상들을 비교하였을때 산발성 환자군과 형제 환자군간에 유의한 차이가 없었다. 4) 산과적 합병증 및 신체 미세기형과 임상 양상들을 비교하였을 때, 형제 환자군에서 분만시간과 회복시 전반적 기능수준간에, 산발성 환자군에서 산과적 합병증의 전체 점수와 발병 연령간에 상관관계가 있었으나 전체적으로 일관된 결과가 도출되지는 못하였다. 위와 같은 결과를 종합하여 볼 때, 산과적 합병증이나 신체 미세기형이 정신분열병의 원인을 밝히는데 유익한 도구가 될 수는 있지만, 가족력 유무에 따라 정신분열병을 보다 동질적인 아형으로 구분하기 힘들다고 생각되었다. In order to test the hypothesis that familial schizophrenics have fewer chances of receiving organic insults during the fetal neural development than sporadic schizophrenics, the authors compared obstetric complications, minor physical anomalies, and other clinical features in sibling schizophrenics, sporadic schizophrenics and controls. Obstetric complications were evaluated by the scale of Lewis, and minor physical anomalies were measured by the Waldrop scale. Sporadic schizophrenics had a significantly higher Waldrop score for mouth than sibling schizophrenics. Although there was some tendency of higher total scores for minor physical anomalies in sporadic schizophrenics, there were no statistically significant differences in obstetric complications and the other minor physical anomalies among three groups. There was no significant correlation between obstetric complications and minor physical anomalies. The clinical features such as age of onset, psychopathology, response to drugs, premorbid functioning, and tardive dyskinesia were not significantly different between sibling and sporadic scizophrenics. In conclusion, while the obstetric complications and minor physical anomalies were suggested to be useful in the search for the cause of schizophrenia, it was difficult to categorize schizophrenics into more homogeneous groups according to family history of schizophrenia using the parameter of obstetric complications and/ or minor physical anomalies.

Objectives The Mental Health Act is an initiative aimed at changing and shaping mental health services and protecting human rights of persons with mental disorders. Since the Mental Health Act was legislated in 1995, four amendments have been made according to the issues that arose from public concerns. However, there are still many debates about the human rights protection of the mentally iII. This study aimed to provide information regarding major aspects of the Mental Health Act by comparing them among several developed countries. Methods Current Mental Health Acts of the state of Michigan in the United States, Scotland in England, the state of Victoria in Australia, and Japan were reviewed. Issues regarding the Korean Mental Health Act were collected from seminar materials, news media contents, and mental health professionals Results The definition of subjects in Korean Mental Health Act was more inclusive than other countries and was derived from a medical classification of mental illness. Family members or guardians were granted important responsibilities for deciding the involuntary admission of mentally ill patients in Korea and Japan. In Western countries, Mental Health Review Tribunals or courts have the primary responsibility for important decisions about mentally ill patients. The regulation of immediate dis- charge after request by voluntarily admitted patients was not enacted in all countries except Korea. The mandatory procedure for involuntary admission in Western countries includes an individual case review with personal interview by a Mental Health Review Tribunal or court. Conclusion The Korean Mental Health Act appears to meet the basic standards of Guidelines from international organizations. Our traditional culture and inherent health systems seem to influence the legal regulation of mental health service and might be related to the problems of human rights protection of mentally ill patients in Korea.

Various kinds of zeolites, such as analcime (ANA), cancrinite (CAN), Na-P1 and sodalite octahydrate (SOD) could be synthesized from Hwangto by hydrothermal reaction in a high-pressure vessel. The adsorption characteristics of Cu(Ⅱ) and Cd(Ⅱ) by Hwangto and its synthetic zeolites were investigated using the chemical and electrochemical surface parameters of these adsorbents. The heavy metal adsorptivity among the adsorbents decreased in the following sequences: Na-P1 > SOD > ANA > CAN > Hwangto. This sequence was the same with the values of surface site density (Ns) of these adsorbents and was correlated inversely with the values of pHpzc (pH of the point of zero charge) and the values of Ka2(int) (intrinsic surface deprotonation constant) of the adsorbents for synthetic zeolites, i.e., the adsorbents with higher values of Ns and with lower values of pHpzc and Ka₂(int) for synthetic zeolites showed higher heavy metal adsorptivity. With increasing pH, the heavy metal adsorptivity increased greatly between pHpzc and pH 6 or 7 because of the steep increase of negatively charged sites for synthetic zeolites, but for Hwangto, it increased broadly because of slow increase of negatively charged sites based on its lower surface sites.

대규모 간척사업이 활발하게 진행되고 있는 인천연안의 해수유동 변화 및 오염물질 운송 양상을 예측하기 위하여 조간대의 노출-침수를 고려할 수 있는 평면 2차원 수치모형을 수립 적용하였다. 해수유동 모형은 정도지점의 현장 측정자료에 대하여 검증을 수행하였으며, 그 결과 주 흐름방향의 유속 및 수위에 대한 계산치가 현장 관측치 재현에 우수함을 보여주고 있다. 그리고, 수립된 흐름모형을 이용하여 영종도 신공항 및 시화방조제 건설 전 \ulcorner후의 조석변화 양상을 모의하는 한편, 흐름모형에서 계산된 대조기 흐름조건하에서 가상의 오염부하에 따른 오염물질 확산 양상을 수치 모의하였다. 수치모의결과, 해역의 개발로 인하여 유속이 감소되고 있으며, 유입된 오염물질은 잘 발달된 협수로를 따라 주로 이동되고 있음을 알 수 있었다 따라서, 인천해역에 대하여 수립된 본 모형은 향후 인천해역의 개발계획에 대한 조석변화 및 오염물질 확산을 예측하는 모형으로 활용될 수 있다 A horizontal 2-D model which includes the wetting-drying treatment technique in the intertidal zone is established for the prediction of tidal changes and contaminant transport due to the development of Incheon coastal zone. The flow model is verified by the measurement data at Jeong-Do, and then the computed values are closely matched to the observed water elevations and velocities of main-flow direction. And then, the tidal change patterns are simulated using this model before and after the construction of the Youngjongdo New Airport and Shihwa Seadike. In the spring tide condition, pollutants transport pattern is also simulated for the arbitrary pollutants loads. By the analysis of this numerical simulation results, the velocities after development are decreased, and discharged pollutants are mainly transported by the advection along a narrow deep trough. Thus, this model can be used as the compatible prediction model for the tidal change and pollutant transport due to the development plan of Incheon coastal zone.

Twenty-four factories registered at the Ministry of Labor as factories using or producing cadmium in 1991 were investigated to know the present state of occupational exposure to cadmium in 1992. Nine factories among 24 stopped using or changed to other substances and 1 factory didn't produce any more, but delivered it to other factories through imports. Therefore, only 14 factories were producing or using cadmium. But, alloying materials were supplied to about 20 and more factories, however, they couldn't be investigated because of limited information. Three factories had less than 50 workers were 3,6 had 50-300 and 5 had more than 300. About 167 workers were exposed to cadmium. According to the classification by process, there were 4 alloy processes, 2 refinary, 2 elctroplating, 2 dry cell making, 1 industrial battery making, 1 duplicator drum making, 1 recycling of battery and 1 copper refinary. 8 factories used metal cadmium, 3 cadmium oxide, 2 cadmium sulfide, and 1 cadmium hyroxide. One factory was importing cadmium stearates only and supplying them to the PVC making factories. The amount of metal cadmium producing in 2 refinary factories was about 50-65 ton per month. The other cadmium compounds were imported. According to exposure level of cadmium air of the 10 factories examined, each factory could be divided into high, moderate and low exposure groups. 1 battery recycling factory and 3 alloy factories were in the high exposure group and their mean air concentrations were 0.06679, 0.05481, 0.02492, and 0.003㎎/㎥, respectively. Refinary and industrial battery making factories were in the middle exposure group and their mean air concentrations were 0.00773 and 0.00613 ㎎/㎥, respectively. Finally, low exposure group were copper smelting, dry cell case making, duplicator drum making and electroplating factory and their mean air concentrations were 0.00096, 0.00071, 0.00057 and 0.00054 ㎎/㎥ respectively.

여성에서 Dehydroepiandrosterone sulfate와 인슐린저항성증후군의 연관성

연구배경: DHEA는 안드로겐 전구체로서 연령 증가에 따라 감소한다. 남성에서 DHEA는 인슐린저항성 및 심혈관질환에 대한 보호 작용을 하는 것으로 알려져 있으나 여성에서는 인슐린저항성과 심혈관질환에 대한 DHEA의 역할은 정립되어 있지 않다. 본 연구는 여성에서 인슐린저항성과 심혈관질환에서 DHEA의 역할을 규명하고자 시행하였다. 방법: 지역사회에서 무작위 추출된 471명의 여성을 대상으로 DHEA보다 반감기가 길고 일중 변동이 적은 것으로 알려져 있는 DHEAS의 농도를 방사면역측정법으로 측정하였다. DHEAS 농도와 인슐린저항성증후군 및 이 증후군을 구성하는 인자들과의 연관성을 관찰하였다. 결과: 1. 인슐린저항성증후군 인자의 빈도는 비만 25.3%, 내당능장애 8.5%, 고혈압 21.9%, 이상지질혈증 6.2%이었으며 인슐린저항성증후군의 빈도는 16.5%이었다. 2. DHEAS는 연령(r=-0.47, p<0.001), 수축기혈압(r=-0.18, p<0.001), 이완기혈압(r=-0.10, p<0.05), 공복혈당(r=-0.10, p<0.05), 포도당부하 2시간 혈당(r=-0.12, p<0.01), 및 중성지방(r=-0.16, p<0.01)과 의미있는 음의 상관관계가 있었다. 3. DHEAS 농도를 사분위수로 나눈 후 연령을 보정한 후 인슐린 저항성증후군 구성요소의 빈도를 관찰하였을 때 DHEAS 농도 감소에 따라 고혈압의 빈도가 유의하게 증가하였다.(p<0.05). 4. 연령(p<0.0001) 및 체질량지수(p<0.05)가 DHEAS에 영향을 주는 인자로 작용하였다. 5. 연령을 보정한 후 낮은 DHEAS농도는 인슐린저항성증후군의 위험인자로 작용하지 않았다. 결론: 여성에서 혈청 DHEAS 농도는 혈압, 혈당 및 혈청 지질 농도와 음의 상관관계가 있었으며, 연령을 보정한 후 DHEAS 농도가 감소함에 따라 고혈압의 빈도가 증가하는 것으로 보아 최소한 DHEAS는 인슐린저항성증후군에 대해 위해 작용을 가지지는 않는 것으로 생각된다. 그러나 DHEAS의 인슐린저항성증후군 및 심혈관질환에 대한 보호 작용을 증명하기 위해서는 이들 대상자를 전향적으로 추적 관찰하여 인슐린저항성증후군 및 심혈관질환의 발생과 DHEAS의 관계를 규명해야 할 것이다. Background: Dehydroepiandosterone (DHEA) is an androgen precursor, and is known to be decreased by the aging process. DHEA has been known to have a protective effect on insulin resistance and cardiovascular disease in men, but remains controversial in women. The aim of this study was to elucidate the role of DHEA on insulin resistance, and the risk for cardiovascular disease, in women. Methods: We analyzed the relationship between DHEA sulfate (DHEAS), known to have a longer half-life and less diurnal variation than DHEA, and insulin resistance syndrome (IRS) in 471 non-diabetic women from an urban community diabetes prevalence study. Serum DHEAS concentrations were measured using a commercially available radioimmunoassay kit. Results: 1. the frequencies of obesity, impaired glucose tolerance, hypertension and dyslipidemia were 25.3, 8.5, 21.9 and 6.2%, respectively, and the frequency of IRS was 16.5%. 2. DHEAS was significantly inversely correlated with age (r=-0.47, p<0.001), systolic blood pressure (r=-0.18, p<0.001), diastolic blood pressure (r=-0.10, p<0.05), fasting serum glucose (r=-0.10, p<0.05), postchllenge 2 hour glucose (r=-0.12, p<0.01) and triglycerides (r=-0.16, p<0.01). 3. As serum DHEAS concentrations, by quartiles, were decreased, the age-adjusted frequency of hypertension was significantly increase (p<0.05). 4. A Multiple linear regression analysis revealed that DHEAS was significantly associated with age (p<0.0001) and BMI (p<0.05). 5. A Logistic regression analysis showed that DHEAS was not associated with IRS after adjustment for age. Conclusion: DHEAS is inversely associated with age. DHEAS has no harmful effect, and may even have a protective role, on insulin resistance syndrome. Prospective examinations of DHEAS and insulin resistance syndrome in women are needed to confirm the mechanism for the association between DHEAS and the development of cardiovascular disease (J Kor Soc Endocrinol 17:675∼684, 2002).
