A case of rapid cycling mania secondary to gamma-knife radiosurgery for the treatment of refractory epilepsy was reported. A 21-year old woman who had a gamma-knife radiosurgical operation for the treatment of refractory seizure two years ago was admitted because of manic episodes. Although seizure was relieved, manic symptoms like decreased need for sleep, elated mood, unprovoked laughing, grandiose delusion and bizarre behaviors were developed 11 months after the operation. These symptoms recurred lour rimes for eight months. There were no past personal and family history of mood disorders. Laboratory examinations including electroencephalogram ana endocrinological study did not show any abnormal findings. The rapid cycling secondary manic was relieved by lithium. She was then discharged after 5 months. Mood change was not significant during follow-up while hypomania emerged by dose reduction. The secondary mania seemed to be caused or triggered by the right temporal lobe damage induced by gamma-knife radiosurgery.

The water-rock interaction and anthropogenic contamination affecting to geochemical composition of shallow and deep groundwaters were investigated in the agricultural area of Myunggok-ri, Kongju. The shallow groundwater is classified into the chemical types of $Ca-HCO_3$ and $Ca-Cl(SO_4)$ and shows weak acid having an average pH 6.2. Deep groundwater shows the uncontaminated composition of the chemical types of $Na-HCO_3$ and Na $(Ca)-HCO_3$ with pH of 8.4~8.8. The grouping approach of chemical data of waters shows the distinguished trend between water composition influenced anthrophogenic input and water composition mainly determined by natural process such as water-rock interaction. The main anthropogenic inputs affecting chemical composition of shallow groundwater are the contaminants such as $K^+$, $NO_3{^-}$, $Cl^-$ having average values of 4.4 mg/l, 22 mg/l, 13.7 mg/l, respectively. The contaminants were probably derived from fertilizer, sweage, septic tank, and stable, etc. The hydrogen and oxygen isotopic compositions indicate that five deep groundwaters were recharged from different altitudes, and that shallow and deep groundwaters were originated from meteoric water. Tritium contents of waters suggest that deep groundwater was recharged before or just after 1950s, and that shallow groundwater is much younger than deep groundwater. The results of this study may serve as a basic data for the future study of shallow groundwater as a drinking water in agricultural area, in Korea.

이 연구는 한반도 동해안 일대에 분포하고 있는 주요 온천에 대하여 화학성분, 안정동위원소, 삼중수소 그리고 헬륨과 아르곤 같은 영족기체의 동위원소 특성을 분석하여 온천유형별 온천수의 지화학적 특성을 밝히고, 영족기체의 기원을 규명하고자 하였다. 이를 위하여 동해안 일대의 6개 온천지에서 11개의 온천수 시료와 14개의 가스시료를 채취하여 분석하였다. 온천수의 수리화학적 특성을 보면 오색탄산온천수를 제외한 모든 온천수의 pH는 $7.0{\sim}9.1$ 범위의 약알카리성 내지 알카리성을 보이며 오색탄산온천의 pH는 5.7의 약산성의 특성을 보였다. 온천수의 토출온도는 $25.7{\sim}68.3^{\circ}C$ 범위를 보였으며 전기전도도는 $202{\sim}7,130{\mu}S/cm$의 넓은 범위로 해운대와 동래온천은 평균 $3,890{\mu}S/cm$으로 높은 값을 보인다. 온천을 용존성분에 따른 분류하면 오색, 척산, 백암, 덕구온천은 소량의 유황가스 함유한 알카리성의 Na-$HCO_3$형으로 분류되고, 해운대와 동래온천은 높은 TDS(총용존고형물질)의 해수형 Na-Cl형을 보인다. 그리고 오색탄산온천은 약산성으로 탄산을 함유한 Na-$HCO_3$형으로 분류된다. 연구지역 온천수의 ${\delta}^{18}O$와 ${\delta}D$값은 각각 $-7.8{\sim}-11.7%o$과 $-57.3{\sim}86.4%o$의 범위를 보여 온천수가 순환수 기원임을 지시한다. 위도가 높아질수록 낮은 동위원소 조성 값을 보이는 위도효과가 잘 나타난다. 일부 해수형온천수의 삼중수소 함량은 거의 0 TU에 가까운 값을 보여 최소 약 50년 이상 체류한 물임을 알 수 있다. 오색탄산온천수를 제외한 온천수의 $^3He/^4He$ 동위원소비는 $0.1{\times}10^{-6}{\sim}1.1{\times}10^{-6}$ 범위를 보여, 대기-지각 혼합선보다 상위에 분포한다. 이는 온천수내 He 가스가 대부분 대기와 지각기원이며, 일부는 맨틀기원의 He 가스가 부분적으로 존재한다는 것을 의미한다. 판 경계부에 위치한 일본의 온천수내 He가스는 대부분이 맨틀기원으로 알려져 있어 판 경계부에서 떨어진 우리나라의 경우와 뚜렷한 차이를 보인다. 그러나, 오색탄산온천에서는 대기기원 He 동위원소비보다 2.4배 높은 값인 $3.3{\times}10^{-6}$을 보여주어 지하 심부의 맨틀기원의 가스가 지각상부 대수층까지 공급된 것으로 해석된다. 온천수의 $^{40}Ar/^{36}Ar$ 비는 대기기원의 값과 유사한 범위를 보인다. The purpose of this study is to characterize the hydrogeochemical characteristics of hot spring waters and to interpret the source of noble gases and the geochemical environment of the hot spring waters distributed along the eastern area of the Korean peninsula. For this purpose, We carried out the chemical, stable isotopic and noble gas isotopic analyses for eleven hot spring water and fourteen hot spring gas samples collected from six hot spring sites. The hot spring waters except the Osaek hot spring water show the pH range of 7.0 to 9.1. However, the Osaek $CO_2$-rich hot spring water shows a weak acid of pH 5.7. The temperature of hot spring waters in the study area ranges from $25.7^{\circ}C$ to $68.3^{\circ}C$. Electrical conductivity of hot spring waters varies widely from 202 to $7,130{\mu}S/cm$. High electrical conductivity (av., $3,890{\mu}S/sm$) by high Na and Cl contents of the Haeundae and the Dongrae hot spring waters indicates that the hot spring waters were mixed with seawater in the subsurface thermal system. The type of hot springs in the viewpoint of dissolved components can be grouped into three types: (1) alkaline Na-$HCO_3$ type including sulfur gas of the Osaek, Baekam, Dukgu and Chuksan hot springs, and (2) saline Na-Cl type of the Haeundae and Dongrae hot springs, and (3) weak acid $CO_2$-rich Na-$HCO_3$ type of Osaek hot spring. Tritium ratios of the Haeundae and the Dongrae hot springs indicate different residence time in their aquifers of older water of $0.0{\sim}0.3$ TU and younger water of $5.9{\sim}8.8$ TU. The ${\delta}^{18}O$ and ${\delta}D$ values of hot spring waters indicate that they originate from the meteoric water, and that the values also reflect a latitude effect according to their locations. $^3He/^4He$ ratios of the hot spring waters except Osaek $CO_2$-rich hot spring water range from $0.1{\times}10^{-6}$ to $1.1{\times}10^{-6}$ which are plotted above the mixing line between air and crustal components. It means that the He gas in hot spring waters was originated mainly from atmosphere and crust sources, and partly from mantle sources. The Osaek $CO_2$-rich hot spring water shows $3.3{\times}10^{-6}$ in $^3He/^4He$ ratio that is 2.4 times higher than those of atmosphere. It provides clearly a helium source from the deep mantle. $^{40}Ar/^{36}Ar$ ratios of hot spring water are in the range of an atmosphere source.

정신분열증에서의 연성 신경학적 증상과 항정신병 약물 치료의 관련성

채정호,정찬호,함웅,이규항,이정균,Chae, Jeong-Ho,Chung, Chan-Ho,Hahm, Woong,Lee, Kyu-Hang,Lee, Chung-Kyoon 대한생물정신의학회 1994 생물정신의학 Vol.1 No.1

정신분열증 환자에서 연성 신경학적 증상이 많이 나타나는 것은 많은 연구에서 확인된 바 있으나 이것이 항정신병 약물 복용 등에 의하여 발생하는 부수적인 현상일 가능성이 배제되지 않고 있다. 본 연구는 항정신병 약물 복용군과 비복용군간의 연성 신경학적 증상 발현의 차이를 알아보고자 시도되었다. 항정신병 약물을 전혀 복용하지 않은 28명과 현재 항정신병 약물로 치료 중에 있는 31명의 정신분열증 환자에서 연성 신경학적 증상을 구조화된 평가척도인 한국어판 신경학적 평가척도로 조사하였고 약물용량과 투여기간 및 부작용과의 관계도 알아보았다. 항정신병 약물 비복용군의 신경학적 평가척도의 총점은 $27.14{\pm}5.66$점으로 복용군의 $19.58{\pm}6.55$점보다 유의하게 높았다 (t=-4.76, P<0.001). 하위 기능영역 중에서도 운동조정(t=-5.52, P<0.001), 복합운동활동 순서화(t=-2.20, P<0.05), 기타 항목(t=-5.14, P<0.001)등의 점수는 비복용군에서 높았다. 감각통합 영역은 약물 복용군과 비복용군 사이에 유의한 차이가 없었다. 약물 용량, 연령, 성별 등을 통제한 후의 조사에서는 총점(F=11.13, P=0.00), 운동조정(F=28.46, P=0.00), 기타 항목(F=10.79, P=0.00)등은 약물 비복용군에서 높았으나 복합운동활동 순서화는 이들 공변량의 영향을 받아 약물 복용군과 비복용군사이에 유의한 차이가 없었다. 약물 복용군에서 현재의 항정신병 약물 복용량은 신경학적 평가척도 점수 중 운동 조정 영역과만 유의한 상관성을 보였으며 약물 복용기간, 부작용 등은 연성 신경학적 증상과 상관성이 없었다. 위와 같은 결과로 항정신병 약물은 정신분열증의 신경학적 증상 발현에 상대적인 영향만을 준다고 할 수 있었으며 연성 신경학적 증상이 정신분열증의 주요한 형질 표지자의 하나가 될 가능성이 있다고 하겠다. 또한 향후 보다 통제된 집단에서의 추적연구가 필요할 것으로 생각되었다. This study was performed to examine the role of neuroleptics may in the development of neurologic soft signs in patients with schizophrenia. Neurologic soft signs were evaluated in 28 neuroleptic naive patients with schizophrenia or schizophreniform disorder and 31 neuroleptic non-naive patients with schizophrenia using a structured tool for measuring neurologic abnormalities, Neurological Evaluation Scale-Korean version(NES-K). Relationship to dose, duration and neurological side effects of neuroleptic treatment were also evaluated. Total scores of NES-K in neuroleptic naive group were significantly higher than those of non-naive group. Scores of motor coordination, sequencing of complex motor acts and others items in functional subcategories were also significantly higher in drug-naive patients. The sensory integration item was not different between two groups. After controlling covariates such ac dose of neuroleptics, age and sex, total scores, motor coordination and others items of NES-K were significantly higher in neuroleptic naive group. However there was no difference between drug naive and non-naive group in the sequencing of complex motor acts item due to effects of these covariates. In neuroleptic non-naive group the dosage of neuroleptics correlated with the motor coordination item, nor were there relationships between duration and side effects of neuroleptic treatment and neurologic soft signs. These findings suggest that neuroleptic treatment may play a only relative role in the development of neurologic soft signs in patients with schizophrenia and these abnormalities may be one of possible trait markers of schizophrenia. To elucidate this opinion, well-controlled, prospective study in same subjects will be helpful.

On the Interaction of QPs and Wh-Adjuncts

정찬호 慶北專門大學(영주경상전문대학) 2000 慶北專門大學 論文集 Vol.18 No.-

The interaction of QPs and wh-adjuncts has been discussed in this paper. It is argued that a proper explanation for the well-formedness of the LF representations of sentences containing traces left by Quantifier Raising (QR) and wh-movements needs to incorporate both an antecedent condition (the Adjunction Condition) and modification typology of adjuncts. The former, stated in (41), defines the domain where an empty category must be bound. The latter classifies behaviors of wh-adjuncts and defines the restriction of their scope to the elements immediately dorninated by the phrase it modifies. Variables bound by nonreferential adjuncts such as manner adjunct how and reason adjunct why cannot play a role in determining scope interaction with QPs, while variables bound by referential adjuncts such as locative adjunct where and time adjunct when can play a role in determining scope interaction. We come to the conclusion that the ambiguity in Qp/nonreferential adjuncts interaction does not involve any trace bound by nonreferential adjuncts, whereas the ambiguity QP/referential adjuncts does involve traces bound referential adjuncts, and that the Adjunction Condition established in this paper yields well-formed LF representations and the Scope Principle successfully accounts for ambiguity and nonambiguity in the interaction of both QPs/wh-arguements and QPs and nonreferential adjuncts.
