A pocket park is valued in securing green space in downtown and improving urban view in the aspect of natural and environmental values, and it signifies a lot as the center of local residents’ community and harmony as well. Since subway exits and surroundings that have high portions in taking up street space due to lack of green space in downtown aren't made full use of, valuable pocket park place. Dangni Pocket Park of subway exits is a park completed with cooperative works and partnership by students, specialists, administrative organizations, businesses and civilian organizations, etc. without support of special budget. The study site was finally chosen to the space between exit No.1 of Dangni subway station, after analyzing the surrounding circumstances, availability and accessibility of the space among the several subway station exits of Saha, Dangni, and Hadan Station in Busan Metropolitan city. For the designing process, The Citizens organization for Million Amenity Park performed the planning and project proceeding, and 19 design drafts were proposed during the class of landscape architecture in Dong-a University. Design review panel members discussed to select the best draft in practical and authentical, and the related experts reviewed and revised to present the final design plan. The construction was conducted was performed under the cooperation between the civil, authorities, and industrial organizations, among which Saha District office managed for the waste treatment and maintenance matters. The graduates of landscape architecture department of Dong-a University and related industrial enterprises supplied landscape materials and related labors, were supported by 20 members of GPM, one of clubs of Dong-a University volunteered durig the most of construction progress, completing the Pocket Park of subway exits through partnership.

In a previous study, hydrolysates of porcine placenta were obtained and the extraction efficiency for proteins and amino acids was compared between sub- and super-critical water extraction systems; optimum efficiency was found to be achieved using subcritical water ($170^{\circ}C$, 10 bar). In this study, the effects of adding ethanol to the subcritical water system were investigated. The lowest-molecular-weight extraction product detected weighed 434 Da, and the efficiency of extraction for low-molecular-weight products was increased when either the concentration of ethanol was decreased, or the extraction time was lengthened from 10 min to 30 min. The highest concentration of free amino acids (approximately 8 mM) was observed following 30 min extraction using pure distilled water. The concentration of free amino acids was significantly lower when ethanol was added or a shorter extraction time was used (p<0.05). Color change of the solution following extraction was measured. There were no significant differences in color between lysates produced with different extraction times when using distilled water (p>0.05); however, using different extraction times produced significant differences in color when using 20% or 50% ethanol solution for subcritical extraction (p<0.05). The range of pH for the hydrolysate solutions was 6.4-7.5. In conclusion, the investigated extraction system was successful in the extraction of $\leq$ 500 Da hydrolysates from porcine placenta, but addition of ethanol did not yield higher production of low-molecular-weight hydrolysates than that achieved by DW alone.

오이속의 조효소액에 존재하는 Superoxide dismutase(SOD)활성의 pH 안정성은 pH 8.0에서 가장 안정하였고 pH5.0~9.0 사이의 범위에서는 비교적 안정하였다. 최적 온도는 25℃였고 열 안정성은 60℃까지는 안정하였다. 100℃에서 5분간 보관하였을 경우에는 12%만이 남아있었다. 오이에 존재하는 SOD 활성이 섭취 후에도 안정한가를 확인하기 위한 실험에서는 위속의 pH와 동일하도록 오이속의 조효소액의 pH를 2.0으로 변형시킨 후 36.7℃에서 3시간 동안 보관 후에 잔존활성이 10%였고, 장내의 환경인 pH 7.0으로 바꾸어 6시간 동안 둔 후 잔존하는 SOD의 활성은 25%로 활성이 증가되었다. 다양한 열처리 후에 잔존하는 오이의 SOD활성은 오이속은 데치기에서(끓는 물에서 2분) 25%, 껍질은 찌는 동안에(3분) 53%, 그리고 속과 껍질로 분리하지 않은 오이는 데치기에서 27%의 활성잔존률을 보였다. 4℃에서는 20일간 보관한 후에 오이속의 조효소액은 81%활성이 있었고, 30℃에서는 17%의 활성이 남아 있었다. 투석한 결과 SOD의 활성은 변화가 없었으므로 오이속에 존재하는 SOD는 적어도 분자량이 12,000 이상의 물질로 추정된다. The superoxide dismutase(SOD) in peeled pericarp of cucumber was most stable at pH 8.0 and relatively stabe between pH 5.0 and 9.0. The enzyme was stable up to 60℃ and retained 12% by heat treatment at 100℃ for 5 min. At pH 2.0, the peeled pericarp enzyme activity was decreased to 10% by incubation for 3 hrs. However, the enzyme activity was increased above 25% after incubating the enzyme at pH 7.0 for 6 hrs. Retention of SOD activity in cucumber by various heating methods was also measured. The residual SOD activities of peeled pericarp and whole cucumber was estimated to be 25% and 27% after blanching (2 min), respectively. The skin enzyme retained 53% of its activity after steaming (3 min). When the peeled peri carp enzyme was incubated at 4℃ for 20 days, the enzyme activity remained about 81%. However, when the enzyme incubated at 30℃ for 20 days, the peeled pericarp enzyme activity decreased to 17% of its original activity. The enzyme activity of peeled pericarp cucumber was not changed after exhaustive dialysis for 3 days, which indicated that the SOD activity in cucumber seems to have molecular weight above 12,000.

목 적 : 정 신분열병 환자의 자기만입 정도에 영향을 미치는 인구학적 변인들 및 질병연관 변인들을 규명해 보고자 하였다. 또한. 환자들의 자기만입과 병식 사이의 연관성. 자기만입과 자존심 사이의 연관성을 알아보고자 하였다. 방 법 : 정신과 의사가 병록지와 면담을 통하여 대상 정신분열병 환자들의 인구학적 변인들 및 질병연관 변인들에 관한 자료를 얻고 환자들의 병식 정도를 평가한 후, 환자들로 하여금 자기보고형의 자기만입 척도와 자존심 척도를 시행하게 하였다. 총 111명의 환자가 연구대상으로 선택되었다. 결과: . 1) 여자가 남자보다 유의하게 높은 자기만입 척도 점수를 나타내었다 2) 질병연관 변인들 중 하위집단 사이에 자기만입 척도 점수의 유의한 차이를 보이는 변은 없었다. 3) 자기만입 척도 점수와 병식 점수 사이에 유의한 상관관계가 없었다. 4) 자기만입 척도 점수와 자존심 척도 점수 사이에 유의한 역상관 관계를 보였다. 결 론 : 본 예비 연구의 결과로 보아 정신분열 병 환자의 병식이 부족한 상태에서도 자기만입이 진행될 수 있으며. 자기만입이 심할수록 환자의 자존심이 저하되는 것으로 생각된다. 또한 여자 환자들이 남자 환자들보다 자기만입에 더 취약한 것으로 생각된다. 따라서 정신분열 병 환자의 이해와 치료를 위하여 자기만입에 관한 지속적인 연구가 필요할 것으로 생각된다. objective : This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. Methods : Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight for the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subjects was assessed from the self-engulfment scale and the self-esteem scale respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. Results 1) The females exhibited significantly higher scores than the males on the self-engulfment scale. 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment scores and the insight 4) There was a significantly inverse correlation between the self-engulfment scores and the self-esteem scores. Conclusion : The results of this preliminary study suggest that self-engulfment may develop despite lack of insight and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.

박춘식,장정욱,유기재,최성민 國立 昌原大學校 産業技術硏究所 2002 産技硏論文集 Vol.16 No.-

This Study investigated a possibility of lateral movement in the reconstruction field of Nongso bridge at Nongso-ri, Joochon-myeon, Kimhae. The methods applied in this study were the judgement formula and the Finite Element Method(FEM). The conclusions are shown in the following. 1) The application of the FEM, as well as the judgement formula resulted in the lateral movement. 2) Bridge abutment and foundation must be constructed after completing consolidation. 3) The occurrence possibility of lateral movement should be judged by the FEM that can re-present field conditions. 4) Lateral movement will take place in the case. Hence, settlement of proper countermeasure method should be followed by the construction.
