Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

The conventional PI controller has been widely used in industrial applications. If it is selected suitable a PI control gain, the PI controller shows very good control performance. But it is very difficult to find the optimal PI control gain. This thesis deals with the speed control of switched reluctance motor using the PI controller with 4-rule based fuzzy logic modifier. Simulation and experimental results show that the fuzzy logic modifier which exhibits a stabilizing effects on the closed-loop system, has good robustness regarding the improperly tuned PI controller. The performance of the PI controller with fuzzy logic modifier is superior to that of the conventional PI controller.

'不可能性 定理'의 經濟學的 再考

金俊輔 서울大學校經濟硏究所 1999 經濟論集 Vol.38 No.2

厚生(welfare)이란 본래 인간의 價値 판단을 목적으로 하는 실천적 規範의 범주이므로 엄격히 따져보면 科學의 대상이 될 수 없다. 따라서 신고전파의 이른바 社會的 厚生函數論과 같은 것은 이중으로 論爭的이다. 첫째로 거기에는 가치 판단 그것이 마치 과학과 같이 다루어져 있으며, 더구나 그가 다루는 厚生이란 목표대상 자체 個人的 功利와 社會的 福祉를 시종 同質의 것으로서 다루는 점 역시 문제의 조건이 아닐 수 없다. 그 가운데 근자의 中心的 厚生理論으로 알려진 '애로우'의 '不可能性 定理'라는 것이 어떠한 구실을 맡아 하는 것인가, 이 또한 틀림없이 個人的 選好의 順位를 토대로 한 전통적 후생함수론에 관한 數理 분석이고 보면 물론 따져 보아야 할 테마이다. 사실 '애로우'의 위의 '定理'는 1951년 스스로 개인주의의 集團化란 표방하에 『社會的 選擇과 個人的 價値』(social choice and indivisual value)란 저작으로써 엄밀한 公理的 厚生論을 설정했다고 알려져 있다. 그리고 그것이 사회적 후생함수의 성립가능성뿐 아니라 政治的 投票決定論, 즉 民主的 多數決原理의 응용론이 되기도 한다는 사실은 유명하다. 이후 學界의 충격적 반응과 더불어 비판론도 적지 않았고, 同書의 개정판(1963년)도 일찍이 나왔으나 오늘날 의연 '애로우'의 個人的 選好의 順位的 集團化를 모형으로 삼은 社會的 價値 판단의 厚生理論이 세계적 主流를 이루고 있음에는 틀림이 없다. 따라서 이 방면의 理論的 혼란이 가중되어 있다는 점, 최근에(1999년) 발표된 '센(A.Sen)'의 "綜合的 厚生論"에 비추어 보아서도 시사되는 내용이다. 여기에 본고는 당면한 '定理'의 본성을 특히 그것의 제약점과 더불어 일단 나름대로 구체화하는 동시에 기대되는 앞으로의 厚生理論을 좀더 巨視的으로 모색하는 입장에 있다. 이에 반하여 논의의 대상은 적어도 時代的 환경을 떠나 개인의 效率的 成長모형론에 그쳐 있다.

經濟的 自然法則의 再認識

金俊輔 서울大學校經濟硏究所 1997 經濟論集 Vol.36 No.2

本稿는 경제적 自然法則의 특징을 주로 價値法則으로서 재인식하되 그것이 바로 近代的 産物로서 資本制 生産기구의 市場경제에서 주어진 필연적 존재란 것, 그에 의한 轉化의 대상인 生産價格 역시 현실적 市場에서 自生이 기대되는 自然價格으로서 市場價値를 반영하는 母價値임을 확인한 바 있다. 그럼으로써 그것은 市場價格에 先行한 不可測的 요인인 동시에 市場價格을 지배하는 기준적 價格=價値라는 점을 檢證한 셈이다. 그럼에도 흔히 이른바 經濟分析이란 것이 경제적 自然運動을 오인한 나머지 法則成立의 과정을 밝혀본다 하되 실은 그것의 특성을 檢證하는 작업에 급급하다는 점을 알게 되었다. 따라서 法則의 存立자체는 분석에 있어서 일단 전제된 조건이라는 것, 더욱 그 存立의 檢證方式에는 自然法則에 대응하는 合理性이 주어져야 마땅하다는 점이 여기에서 강조된 결론이다. 이 점은 다만 경제적 自然法則에 限定되지 않는 經驗科學 일반에 걸친 方法論의 요구이기도 하나 이른바 價値의 無用論이나 價格 '轉化問題'를 논의함에 있어서 각별한 인식의 기점이 되어 있다. 價値 그것은 정작 人間 사회와 物質的 세계를 연결시키는 自然的, 그리고 物神的 요인임에 틀림이 없으며, 본래 人爲的 소산이 아닌 까닭이다.

This experiment was conducted at the Seoul National University Arboretum at Seodun-dong, Suweon, Kyeonggi-do, Korea (1) to find out methods killing Robinia pseudoacacia L. effectively and (2) to minimize ecological and aesthetic problems. Glycine and 2, 4-D were treated in several concentration following the saw-scratching and cutting of stems on July 22 and 29, 1985. The results were measured on October 17, 1885. The results obtained were as follows: 1. Ecological problems were decreased by these methods. 2. In case of herbicides treatment on section area, aesthetic problems were minimized, and amounts of herbicide consumption were five times as little as in case of spraying plants with herbicides. 3. The death rate amounted to 100% when the ratio of Glycine solution to water was 1:3, so that the concentration, 1:3 was most economical to kill the tree throughly. 4. The death rate amounted to 100% when the ratio of Glycine solution mixed with 2, 4-D to water was 1:4, therefore Glycine solution mixed with 2, 4-D was more effective than pure Glycine solution. Since 2, 4-D solution was less expensive than Glycine solution and only small amounts of 2, 4-D solution was added, it was most economical and effective method that Glycine solution mixed with 2, 4-D was diluted to the concentration, 1:4 and treated on the stem.

The third year's results on effects of surface fire on frest vegetations and soil properties were investigated in Mt.Gwanak, Kyunggi-do successively after the study of the first year's effects in the same place. Organic matters in soil had increased just after fire and whatsome decreased during 1 year after fire, and resulted in percentage that was less than unfired area in the third year after fire. The pH of subsoil was continuously increasing from just after fire till after 1 year, but decreased somewhat in the third year after fire. More exact classification into Increasers, Decreasers, Invaders and Neutral species was possible in the third year's study. According to comparison of similarities, the vegetational structure of the species at fired area has been gradually restoring to original state as time goes by.

The shallow soil depth and severe rock exposures on the hillslopes in the Kwanak aboretum area which resulted from the heavy soil erosion have made very poor growth of forest vegetation. In order to establish the forest vegetation in this area, it is urgent to recover the fertility of soil and the productivity of existing trees. For this reason, fertilization experiment (using the briquet compound fertilizer) was conducted on summer and autumn season in 1983 with the 4 main native species (Pinus densiflora, Pinus rigida, Juniperus rigida, Rhododendron schlippenbachii) growing on these eroded hillslopes. Result in 1985 and 1986 of this experiment represented that the fertilization was effective toward both height and root-collar diameter growth of trees and spring fertilization was, relatively, more effective than autumn fertilization. It also represented that effects of fertilization to P. rigida were more than those to other species. Therefore, besides the engineering methods and afforestation measures for soil erosion control, rapid establishment of vegetation through conservation and recovery of existing trees by fertilization is available measures for the rehabilitation of rockily eroded hillslopes like Mt. Kwanak area.

辛俊煥,李峻雨,兪鐘德,禹保命,金景河 서울大學校農業生命科學大學附屬樹木園 1985 서울大學校 樹木園 硏究報告 Vol.- No.6

樹木園 造成豫定地를 對象으로 土壤 水分含量과 植生을 調査하여 앞으로의 樹木園 造成에 必要한 情報를 얻음과 동시에 樹木園 造成에 따른 植生破壤後 原來植生에 關한 情報가 必要할 때 參考하기 爲하여 1985年 6月 12日에 本 調査를 實施하였는데 그 結果는 다음과 같다. 1. 全體的으로 겨이삭(Agrostis clavata var. nukabo)의 優占度가 매우 높았으며 씀바귀(Ixeris dentata)와 흰씀바귀(Ixeris dentata var. albiflora)는 극히 乾燥한 곳을 제외하고는 대부분 優占度가 높았다. 濕한 곳에는 왕비늘사초(Carex maximowiczii), 기장대풀(Isachne globosa) 等이, 극히 乾燥한 곳에서는 잔디(Zoysia japonica)가, 보통 乾燥한 곳에서는 그늘사초(Carex lanceolata), 김의털(Festuca ovina) 등이 優占度가 높았다. 2. 특히 稀貴植物인 선제비꽃(Viola raddeana)群落과 진퍼리용담(Gentiana scabra var. buergeri for stenophylla)이 Block 3(습지)에 있으므로 앞으로 이 區域은 注意깊게 保存되어야 할 것이다. 3. 土壤 水分含量이 最低 14.7%에서 最高 88.9%까지 分布하여 乾濕의 差異가 심하게 나타났다. 특히 調査 時期가 乾燥期인데도 土壤 水分含量이 70%가 넘는 곳이 3개소나 된다. 이 곳은 地下水位가 높아서 濕地이므로 濕地植物園을 造成해야 될 것이다. 植生의 造成狀態도 區域에 따라 變異가 심하게 나타났기 때문에 이 林地가 매우 不安定한 狀態에 있다고 볼 수 있을 것이다. Soil moisture contents and vegetation of the forest land planed to establish the Suweon Arboretum had been investigated to obtain some informations for establishing arboretum, and also for keeping the original vegetation composition data after the arboretum was established. The results obtained in this investigation could be summarized as follows: 1. In general, the coverage of Agrostis clavata var. nukabo was very high. The coverage of Ixeris dentata and Ixeris dentata var. albiflora were high except for very arid blocks. Coverages of Carex maximowiczii and Isachne globosa were high in wet blocks. The coverage of Zoysia japonica was high in very arid blocks and that of Carex lanceolata and Festuca ovina in arid blocks were high. 2. Soil moisture content was distributed from 14.7% to 88.9%. Especially the fact of the high moisture content (74.7, 77.5, 88.9%) in dry season implied that the ground water level of this area was high. The vegetation composition of this forest was varied, too. Therefore, it is considered that the stability of this forest was fragile.
