국내산 카올린으로부터 알루미늄황산염수화물을 합성하고, 이의 특성 및 열분해에 따른 알루미나의 γ→α변태에 미치는 Fe₂O₃의 첨가효과가 X-선회절분석, 시차열중량분석, 주사전자현미경, 플라즈마분광분석, BET법을 이용하여 검토하였다. 합성된 2 ㎛정도 크기의 판상입자형태로 구성된 고순도 알루미늄황산염은 Al₂(SO₄)₃·18H₂O로 동정되었으며, 이는 150℃ 부근에서의 탈수반응과 750℃부근에서의 탈황산반응을 경유하여 1000℃에서 결정성이 낮은 γ-Al₂O₃로 변화하였고, γ→α변태는 1200℃정도에서 일어났다. 0.1 wt% Fe₂O₃를 첨가한 경우의 1200℃하소물에서 생성된 FeAl₂O₄스피넬은 알루니마의 γ→α변태를 억제시켰으며, 그 이상의 양을 첨가한 경우와 1300℃로의 하소온도를 증가시킨 경우는 FeAl₂O₄의 α-Al₂O₃와 Fe₂O₃로의 분해 및 이온확산속도의 증가로 인하여 α-Al₂O₃생성이 촉진되었다. Aluminum sulfate hydrate has been prepared from the domestic kaolin, and its characteristics and the effect of Fe₂O₃addition on the γ→αtransformation of the resulting alumina have been investigated by means of the XRD, TG/DTA, SEM, plasma spectrometer, and BET methods. The aluminum sulfate having high purity and 2 ㎛-sized plate-like structure particles was identified as a crystalline Al₂(SO₄)₃·18H₂O, and decomposed to γ-Al₂O₃at 1000℃ via dehydration at ∼150℃ and desulfurization at ∼750℃. γ-Al₂O₃transformed to α-Al₂O₃at 1200℃. After calcination of the aluminum sulfate with addition of 0.1 wt% Fe₂O₃at 1200℃, the formation of FeAl₂O₄spinel prohibited the γ→αtransformation of the alumina. However, the addition of > 0.1 wt% Fe₂O₃and the increase in calcination temperature to 1300℃ accelerated the γ→αtransformation, due to the decomposition of FeAl₂O₄to α-Al₂O₃and Fe₂O₃and the velocity of ion diffusion, respectively.

The major cause of the industrial accidents is often induced by the human error. It brings about all kind of accidents. Moreover, the more the information and system complicates, the more the human error brings about. So the active accident prevention policy by human behavior, life style, culture, and psychology should develop at this time. Especially, the behavior models have provided the accident proneness concept through the life change unit factors. According to the existing studies on the life change unit models, the oriental behavior models differs from the western model in the life style and ideas. Therefore, the purpose of this paper is to develop the proposed life change unit model by the improved life change unit factors, and to evaluate its application in real fields. The proposed model can be simply applied in real fields in order to minimize the industrial accidents

姜琳雅,李孝眞 服飾文化學會 1999 服飾文化硏究 Vol.7 No.6

As sports infiltrates each field of modern society and becomes familiar, sports wear was changed functionally and was introduced and enveloped into everyday dress. Modern sports wear has been the settled in everyday life deeply and become the clothes of life which are worn regardless of place, time and age. The aim of this paper was to clarify what kind of fashion of sports style would be given to the modern people. In this study, sports wear which has become everyday dress was classified from a gender point of view. It was divided into masculine image, feminine image, and neutral image. Sports wear of masculine image generated a silhouette which emphasized the shoulder with the aspiration for youth and health. Wide shoulder was considered as the symbol of masculine beauty and the expression of healthy beauty. It was reflected well in body conscious look. And owing to the development of up-to-date materials, innovation of design, and the study of human body technology, the functional character was settled in the sports wear which showed masculine image. Sports wear of feminine image was represented fashion of body exposure, body feet with body conscious look, and romantic mode. This image was expressed fashion as comforts, pleasant, active design, materials, color, and romantic feminine beauty. Sports wear of neutral image was expressed into unisex clothes. This cloths have no difference in gender, age, and class. It was used as casual sports wear. In the 1960s, young generation participated in such street sports as street basketball and skate. They usually wore the sports wears of neutral image such as cycling, skating, and ski. In the materials of sports, the development of up-to-date material like lycra made the sayings lifelike, "up-to-date material is the second skin" It show that glamorous feminine image and strong masculine image coexisted. The contemporary concept of sportswear is no longer limited to those clothes for sports found in such places like tennis court or swimming pool. Now, the sports wear become more like casual activity wear all classes of people can enjoy in their life regardless of where they are, when they wear, and even how old they are.

강효진,정순호 釜慶大學校 1999 釜慶大學校 論文集 Vol.4 No.1

The learning performance of Second-Order Recurrent Neural Network(SRNN) has been improved for inferring regular language. But it has not tried to imporve it from the aspect of the number of states. This paper shows there is trade-off relationship between the computation time and the number of epochs. For the fixed number of states, the smaller the number of the states is, the shorter the computation time will be and the more the number of the epoch will be increased. We define cost function of the number of epochs and the computation time and find experimentally the optimal number of states using it.

강효정,강지윤,곽병주,정영기,노재성 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.5

연구목적: 본 연구는 생쥐 태자의 대뇌피질 세포 일차 배양을 이용하여 할로페리돌로 유도한 신경세포의 사멸에 대해 신경 성장인자인 brain-dervied neurtrophic factor(BDNF), Neurotrophin 4/5(NT 4/5)와 인슐린 유사 성장인자인 insulin-like growth factor Ⅰ(IGF-Ⅰ)및 IGF-Ⅱ의 조절효과를 실험한 것이다. 방법: 생쥐 태자의 신경세포를 배양한 후 할로페리돌을 처리하여 신경세포의 사멸을 유도하고 이에 대한 성장인자의 효과를 정량적으로 분석하였다. 결과: 30M의 할로페리돌을 배양한 일차 대뇌 신경세포에 24시간 처리하면 광범위한 신경세포의 사멸이 유도된다. 이때 신경세포는 세포의 응축, DNA의 단편화와 응집, 세포막보다 핵막의 이른 붕괴 등 고사 형태의 신경세포 사멸 특성을 보인다. 할로페리돌과 더불어 신경성장인자인 BDNF, NT 4/5 및 인슐린 유사 성장 인자인 IGF-Ⅰ 혹은 IGF-Ⅱ를 동시에 처리할 경우 용량 의존적으로 신경세포의 사멸을 억제한다. 결론: 본 연구의 결과는 할로페리돌에 의한 신경독성이 성장인다들에 의해 억제될 수 있음을 보여주는 것이며, 장기적인 항정신병약물의 사용 후에 발생하는 부작용인 지발성 운동장애의 한가지 원인 가설로 대두되고 있는 항정신병 약물에 의한 신경독성을 신경성장인자에 의해 억제할 수 있을 가능성을 제시하는 것이다. 중심단어:할로페리돌·고사·세포사멸·고사·BDNF·NT-4/5·IGF-Ⅰ·IGF-Ⅱ. Objectives: We examined the effects of neurotrophins and insulin-like growth factors on cell death induced by haloperidol, a typical anti-psychotic agent. Method: Neocortices from 14- or 5-daysold fetal mice for neuron-glia co-cultures were used for this experiment. Result: Twenty-four hours treatment of mouse cortical cell cultures with 30 M haloperidol-induced wide spread neuronal apoptosis characterized by cell body shrinkage, DNA frag-mentation and condensation. Concurrent treatment with growth factors, BDNF, NT4/5, IGF-Ⅰand IGF-Ⅱ, protect the neurons from the haloperidol-induced neuronal apoptosis(HINA) in a dose dependent manner(10-100ng/ml). Conclusion: The present study suggests the possibility that haloperidol toxicity can be hampered with growth factors. Further study about the mechanism underlying the protective capacity of the growth factors on HINA may lead to the development of the new protective strategy for tardive dyskinesia. KEY WORDS:Haloperidol·Apoptosis·Neuronal death·BDNF·NT4/5·IGF-Ⅰ·IGF-Ⅱ.
