Today, many people stay lot of time sitting on chair in their life. If a sitting posture is not correct, there is some trouble with the waist. And if it goes on long time, sometimes it cause the hurts of waist or the deformded spinal column. A crouched posture is an obstacle to breath and it give rise to drowsiness because the lack of oxygen. Sitting posture is a habit so people can't feel it oneself and look over some kind of risks. It analyzes a condition of muscles by measuring EMG of spinal both side of spinal-bones. It can have a right sitting posture by the analyzing that increasing of muscles tention in one or the other side of muscles when the posture inclines on one side or ahead.

고체상 추출법을 이용한 Phthalate Esters의 분석방법 연구

The study was carried out to evaluate the new analytical method of phthalate esters(diethyphthalate, di-n-butylphthalate, butylbenzylphthalate, bis(2-ethylhexyl)phthalate), one of the endocrine disruptors, which were performed by GC/MS-SIM(seleted ion monitoring). The phthalate esters were extracted from water samples using solid-phase extraction on C_18 columns. It investigated that the extraction recovert rate of phthalate esters with different solvents and solvent volume. The optimal solvent was dichloromethane and proper volume of dichloromethane for recovert of phthalate esters was 4 mL. There were good linearities(above R^2=0.9975) in the range 0.01∼0.50㎎/L,and the detection limits were below 0.01∼0.03㎍/L.The recovert rates,RSD and MDLs for phthalate esters were 80∼114%,5.0∼8.1% and 0.03∼0.11㎍/L,respectively. This method shows a good precision of phthalate esters.

This study was conducted to analyse the correlation between the ADL dependency and life satisfaction. Data were collected from the 102 home resident eldery who have no dementia by cognition test. The age distribution f subjects were 65 years and over The data were collected from January 16th to February 15th, 1997. The instruments used for this study were a survey of general characteristics(10 items), physical function(15 items), life satisfaction(20 items). The data were analysed by using an SPSS program and included percentage, t-test, ANOVA & Pearson correlation coefficient. The result of the study are summarized as follows: 1. The mean of ADL dependency score was 5..912 in a possible range of 15 to 60 when 15 indicates high dependency and 60 incicates low dependency. 2. The mean of life satisfaction score was 20.363 in a possible range of 0 to 40 when 0 indicates low life satisfaction and 50 indicates high life satisfaction. 3. The relationship between ADL dependency and life satisfaction for old people in home proved to be of statistically highly negative correlation(r=-.2553 P=.01). 5. General characteristics related to life satisfaction was educational status, household status, economic status, personality, perception of health(P<0.05). In conclusion, it was identified that ADL dependency is the important variable influencing the life satisfaction of the elderly. Therefore, more efforts are needed to decreased the ADL dependency of the elderly to enhance life satisfaction of the elderly.

經濟水域에 관한 硏究 : 그 槪念의 史的發達을 中心으로 with special reference to the development of it's concept

The 21st Certury will be an age of Sea. Not only we will obtain our necessary energy in the sea but also we will reside there. In this respect, it is proper to say that sea is a lifeline for the mankind. Therefore we can say that it is our fundamental duty to regulate the marine order and to formulate marine conditions for natural preservation. For such purposes the U N has last its 3rd Conference on the Law of the Sea to promulgate the marine orders from 1973 up to now. The basic problems which haul been suspended on the desk of the 3rd Conference on the Law of the Sea were the limit of territorial sea, the passage of international straight, the exploitation of deep sea-bed, the sea pollution by ship, scientific research of marine materials, and the problems of exclusive economic zone. Especially among them, we are interested in the proposals of 12 miles of territorial sea and of 200 miles of exclusive econonic zone. In this article, the writer attempted to bring light on the problem of exclusive economic zone, historical evolution of the concept of economic zone and relative proposals presented at the regional or international conferences. This article contains following contents : 1.Introductory Notes 2.Historical Background of Economic Zone 3.Decisions and Decralations of the Regional Commumities 4.The 3rd Conference on the Law of the Sea and Economic Zone 5.Conclusion.

결핵군 55 kDa 항원의 면역학적 분석

Identification and characterization of mycobacterial antigens are critical for evaluation of their role in diagnosis, vaccination, and pathogenesis of mycobacterial diseases. An attempt has been made to immunologic characterize the 55 kDa protein antigen of Mycobacterium tuberculosis H37Rv which attracted our interest because it is present in high concentration in 50-80% ammonium sulfate fraction of the culture filtrate. Two monoclonal antibodies (MAbs) directed to 55 kDa antigen were produced. MAbs MT55-1 and MT55-2 reacted with a single 55 kDa protein band. On examination of degree for cross-reactivity with other mycobacterial species by enzymelinked immunosorbent assay (ELISA) and immunoblotting, these antibodies reacted strongly with M. tuberculosis and M. bovis BCG, and reacted weakly with M. marinum and M. smegmatis. To investigated the subcellular distribution of MAbs defined epitopes in the 55 kDa antigen within the mycobacterium, we isolated three major subcellular factions of M. tuberculosis, namely, cell wall, cytoplasmic membrane, and cytosol, by a simple fractionation procedure. MAb MT55-1 reactive cpitope was found in the cytosol when tested by immunoblotting. A sandwich ELISA was initially developed for detecting 55 kDa antigen using MT55-1 MAb in mycobacterial culture filtrate before detecting it in clincal specimens. The minimal detectable concentration was 1.0 ㎍/m1 for M. tuberculosis culture filtrate and 100 ㎍/ml for sonic extracts of M. bovis BCG and M. marinum, respectively. But the 55 kDa antigen was not detected in sonic extracts of other mycobacterial species examined. Although further evaluations are required, this study suggests that the 55 kDa antigen may be of interest as potential diagnostic reagent.

The purpose of this stud,' was to examine structural problem which occur in case of enlarging inner space and to show the solution. Shear experiment was performed to insure unification of the existing structure and steel frame in case of acting lateral force like seismic effect and wind effect. Also, bending experiment was performed to consider deformation of vertical direction due to subsidence of extension frame. Design range of connection was proposed by various test.

This study was carry out to examine the treatment methods of waste water contaminated with mercury by mercury resistant bacteria Pseudomonas spp Isolated from the soils. The results obtained from this study were as follows 1. The mercury contents was respectivelly 2.4ppm, 0.8ppm and 0.3ppm at A, B, and C site from the soils polluted with mercury. 2. 12 strains of bacteria which showed a remarkable tolerance against Thimerosal was isolated from soils contaminted with Mercury. 3. Isolated bacteria from 40ppm of Thimerosal concentration was identified as Pseudomonas spp. by morphological and biochemical test.
