The purpose of this study was to investigate changes of plasma epinephrine and norepinephrine during maximal exercise in various glycogen conditions. The subjects were composed of 7 male college students. They performed graded exercise test by way of bicycle ergometer in normal glycogen condition, glycogen-depleted condition and glycogen-loaded condition. Glycogen depletion and loading condition were formed as a results of exercise and dietary. plasma epinephrine and norepinephrine were analyzed of blood samples extracted every 3 minutes until exhaution. On the basis of the results analyzed in this study, conclusions were drawn as follow. 1. Plasma norepinephrine in this study, conclusions were drawn as follows. condition with work loads, and difference between glycogen-loaded condition and glycogen depleted condition was significant (p<0.05) from the work load of 120W. 2. Change of norepinephrine/epinephrine was increased in both normal glycogen condition and glycogen-loaded condition with work loads, and differences among three conditions were not significant on the whole.

본 논문은 지능 기법과 영상처리기법을 이용하여 특정 대상물의 절단위치를 검색하는 방법을 제시한 것으로서, 최근에는 기존의 아날로그 센서를 대신한 CCD(Charge-Couple Decive)카메라로 얻어진 화상 데이타(data)를 이용하여 물체의 정보를 추출하는 방법이 많이 응용되고 있다. 최근에 영상의 형태학, 신경망, 지식기반의 영상 해석 시스템에 대한 관심이 높아지면서, 거의 모든 분야에 화상처리기법들이 사용되어지고 있다. 따라서 본 논문에서는 실시간 그레이 레벨의 입력 화상에 대하여 영상처리기법을 이용하여 특정 물체의 특정위치검출 방법을 제안하고, 실제의 시스템에 적용한 예를 제시하려고 한다. In this paper proposed detecting specific position of the object using intelligent method and image processing. Recently instead of classifying the object by shade using existing analog sensor, app.y a theory to detect of the object information by using image data from CCD camera. It takes interest in the morphology of image, neural networks and image analysis system on knowledge base. and now days, image processing method was used in the most part of field. So, In this paper proposed detecting method on specific position of specific object about real time gray level input image using image processing method and application case in real system.

본 연구는 대학생의 학업성취 수준을 사전에 선정된 사회 문화적 배경요인에 따라 실증적으로 분석하여 그 실태를 알아보는데 목적이 있다. 본 연구는 연구주제와 관련된 선행 문헌고찰을 바탕으로 대학생의 학업성취를 인지적 측면에서 ① 실제 학점 평균과 ② 지각된 성취수준(전공지식 습득, 교양지식 습득, 논리·분석적 사고력, 창의력) 등 두 가지로 개념화하였다. 그리고 학업성취와 관련된 사회 문화적 배경요인은 크게 대학생의 ① 개인적 배경요인, ② 가정배경요인, ③ 대학배경요인 등 세 가지로 구별하였다. 본 연구의 대상은 전국에서 표집된 6개 종합대학 1,781명의 대학생들이다. 이들을 대상으로 학업성취요인과 사회 문화적 배경요인들을 설문화하여 수집된 자료를 분석한 결과, 개인적 배경변인에서는 계열별, 거주형태, 일일 평균 공부시간 등의 변인은 학업성취에 차이를 가져오는 것으로 나타났다. 가정 배경변인에서는 출신지역과 부모의 학력 정도에 따라 학업성취 수준이 다르게 나타났다. 한편, 대학 배경변인 별로는 대학설립 유형, 학교 소재지, 입학전형 방식 등의 변인들이 학업성취 수준의 차이를 가져오는 것으로 밝혀졌다.

The purpose of this study is to analyze 'how swimming' for twelve weeks affects the body development of middle-aged women. An investigation into the body development of thirteen women in a two-month period and a one-year period was performed. Each woman that participated in the swimming trials was asked to continually practice one hour in the morning three times a week before and after the investigation. The study arrived at the following conclusion. 1) The weight after swimming was found to have decreased significantly by 0.7kg in the case of the unskilled group and 0.6kg in the case of the expert group. 2) FAT(%) before and after investigation had similarly decreased by 2% in the case of the unskilled group and by 1.7% in the case of the expert group. FAT percentages(%) of the unskilled group were reduced by more than 0.3% when compared to the expert group. 3) FAT mass(kg) before and after the investigation had similarly decreased by 1.3kg in the case of the unskilled group and by 1.1kg in the case of the expert group. FAT mass(kg) of the unskilled group was reduced by more reduced by more than 0.2kg in comparison with the expert group. 4) The variation of lean body mass(kg) before and after the investigation had increased by 0.8kg in the case of the unskilled group and by 0.5kg in the case of the expert group. Lean body mass(kg) of the unskilled group increased by more than 0.3kg in comparison with the expert group. 5) Total body water before and after the unskilled group and expert group didn't change. In summation, swimming for one hour three times a week was found to reduce the FAT(%) and FAT mass(kg) of middle-aged women.

AA-NAT cDNA was obtained by RT-PCR technique from total RNA of rat sacrified at night(02:00am). pCRNAT was cloned using the pCRII vector with insertion of AA-NAT cDNA(about 1.4 kb) at EcoRI site. For the expression of the gene, pQECNAT was subcloned, in which the coding region of AA-NAT was inserted into expression vector pQE30 at BamHI and HindIII sites. According to the experimental results, Escherichia coli strain M15, transformed by the expession vector pQECNAT, was selected as a host to express AA-NAT gene with the induction of isopropyl β-D-thiogalactoside(IPTG). Optimal condition for the expression of AA-NAT gene was achieve from the experimental results, showing that the expression of the protein was inducible much 19.800 ± 2,200 dpm per ml of culture volume in 4 hours at the concentration of 2 mM IPTG. Partial purification through the affinity column(Ni-NTA agarose) binding to the continuous 6 histidine residues of protein resulted in 5 times more increase in the specific activity of AA-NAT than that of the homogenate of bacterial pellet. These experimental results will provide basic data in further study for the enzymatic kinetics and antibody production of AA-NAT.

It is considered a general experience that migration from rural to urban areas will go on in any developing countries pursuing economic development through industralization. In Korea, migration is considered one of the serious socio- economic problems because it has been made excessively fast than any other countries' experiences. The socio- economic problems originates in migration can be classified in two ways ; the one is the overpopulated problems of urban areas and emptied villages problems of rural areas, and the other is the shartage agricultural labor farce problems symbolized by the increasing idle cultivated land. To relieve migration effectively, the developing policies should be converted from pursuing fast industralization and urbanization to balance growth between areas and industries. Moreover problem solving political measure should be converted from partial and corresponding approaches to total approaches containing economic, social and institutional side-view.

서울 대기 에어로솔의 물리적 특성 : 0.01~1.0㎛범위 에어로솔의 표면적 및 체적분포의 월변화

김형관,김필수 漢陽大學校 環境科學硏究所 1988 環境科學論文集 Vol.9 No.-

입자 크기 0.01~1.0 ㎛범위 서울 대기 aerosol의 표면적 및 체적의 월변화를 1984년 5월부터 10월에 걸쳐 전기적 aerosol분석기로 결정하였다. 그 결과 표면적 분포는 0.13 ㎛ 근처에서 극대를 가지는 一山型 곡선을 보였다. 체적분포는 0.2 ㎛ 근처에서 극대를 나타내며 직경 1.0 ㎛ 이상에서 제2의 극대가 있을 가능성을 보였다. 이러한 분포는 직경이 커질수록 입자의 개수가 점점 줄어드는 입자수 분포와는 판이하게 다른 것이었다. 표면적 및 체적분포의 월변화는 춘계에 최고의 농도분포를 보이고 하계에 최저를, 그리고 추계에 점점 증가하는 양상을 나타냈다. 이러한 계절변화는 자연환경과 기상요인의 변화와 밀접히 연관된 것이었다. Monthly variation of surface and volume distributions of Atmospheric aerosols over the size range 0.01~1.0 ㎛ has been determined using an electrical aerosol analyzer in Seoul from May through to October 1984. The results indicate that the surface distribution reveals a monomodal curve with its maximum in the vicinity of 0.13 ㎛ for each month, while the maximum of the volume distribution appears at about 0.2 ㎛ suggesting a possible existence of second maximum somewhere D>1.0 ㎛. These distributions are quite different from the aerosol number distribution which is characterized by a continous decrease of number concentration as increasing particle size. The monthly variation of the surface and volume distributions shows their highest values in spring and lowest in summer. followed by a gradual increase in autumn. The seasonal variation is closely related with change of natural environment and meteorological factors.
