상완골 원위부 과간 골절은 소아에서는 매우 드물게 발생되는 골절로 대부분 주관절의 굴곡상태로 주관절 후방부에 직접적인 충격에 의해 발생하는 것으로 보고되고 있다. 전위가 없거나 경미한 경우 도수적 정복술 혹은 도수적 정복술 후 경피적 핀고정술을 시행하며, 전위가 심한 골절이거나 도수적 정복술이 불가능한 경우 관혈적 정복술 후 핀고정술을 시행하는 것으로 알려져 있다. 저자들은 전위된 상완골 원위부 과간 골절 환아 2예에서 각각 도수적 정복술과 관혈적 정복술 후 K 강선 고정술을 시행하여 만족한 결과를 얻었기에 보고하는 바이다. Intercondylar fractures of the distal humerus are very rare in children. The pattern of the fracture would suggest that the mechanism of injury involves a fall directly on the flexed elbow. Most agree that the undisplaced fracture can be managed conservatively. With increasing displacement and comminution, the opinions tend to differ. We suggest that closed reduction with percutaneous K wire pinning and open reduction with percutaneous K wire pinning offer a satisfactory methods by which to treat displaced intercondylar fracture in children.

가족중심의 사회사업실천연구(1) : Make a Restart from Mary Richmond in Korea Mary Richmond에서 부터 다시 시작하라

김수환 慶星大學校 1994 論文集 Vol.15 No.3

Family centered social work practice is a model of social work practice wihich the family is located in the center of the unit of attention or the field of social work activities in America. The relationship between social work and family stems from early social work practice. The first professional practice journal was called <The Family>, and now it is called <The Families in Society>. Social casework, as a method of social work practice, was born in a nationwide network of agencies called "family service"agencies. Mary Richmond was in the center of development of early social work. She developed a professional model of casework and devised the now familiar practice steps of study, diagnosis, treatment. The unit of steps was the family, Richmond translated her conviction about the importance of the family into her conception of social work practice. But, in 1920-1950, emphasizing a psychological/individualistic view, a lot of practitioner believed that the adaptation of an individual to the environment depends upon his mental makeup. The Family agencies which had originally defined the family as the case shifted to an individual focus in social work practice. The fifties saw a return to the family as the unit of attention. Social workers emphasize the importance of understanding family interaction in case situations. They define family centered social work as practice which is based on an understanding of the social and emotional needs of the family, and believed that the improvement of the social functioning of the family unit is achieved by direct or indirect treatment of the individual family member. In reviewing the relationship between social work and family, the family has sometimes been in the spotlight and at other times in the shadows. Today, family centerd social work is different from family therapy which is very popular in America. It is a theory and practical model on social work, not a theory on family therapy. Social worker co-work with other professionals in family therapy settings. We don't have any native practice model or theory about family social work practice in Korea. We need Mary Richmond.

We analysed 404 patients with primary lung carcinoma who were treated at Soonchunhyang University Hospital from July, 1985 to september, 1993 in order to investigate the survival rate and epidemiolgical properties of primary lung cancer. They were 330 males and 74 females. The most prevalent decade was seventh. In terms of cell type, the squamous cell was 225 patients (55%), and adenocarcinoma, small cell, mixed type was 21%, 19%, 4%, respectively. Among non-small cell lung carcinoma, stage Ⅲa was the most prevalent one(92%). In case of small cell carcinoma, the limited stage was 64%. The 12-, 24-, 36- month survival rate of total patients was 57%, 31%, 22%, respectivley and median sruvival time was 15 months. The 36-month survival rate tended to be longer in non-small cell lung carcinoma than that of small cell lung cancer, but there was no difference between two groups, statistically. In non-small cell carcinoma, The 36-month survival rate and meidan survival time were longer in the stage Ⅰ and Ⅱ than those of Ⅲa, Ⅲb, Ⅳ (80% versus 38%, 22%, 0%, p<0.05). According to involvement of lymph node, the 36-month survival rate was longer in NO and N1 than those of N2, N3 (61.9%, 48.7% versus 17.7%, 17.3%, p<0.05). In small cell carcinoma, The 36-month survival rate and median survival rate were higher and longer in limited stage than those of extensive stage(16.1% and 13 month vs 10% and 8 month, p<0.05). In conclusion, we report here the incidence of primary lung carcinoma and the survival rate of paients with primary lung carcinoma who were treated in Soonchunhyang University Hospital.

구동환,하상우,조수현,박기문,김동운,강국희 성균관대학교 생명과학자원연구소 1997 生命資源科學硏究 Vol.4 No.1

The objectives of this study were to investigate the optimal condition for growth and highly concenterated culture of Bifidobacterium longum (Bif longum). The effects of additives were compared with titratable acidity and viable cell counts, and 10% reconstituted skim milk (no additive) was used as a control. Correlation coefficient for the growth of Bif. longun between CO_2 anaerobic jar method and overalaid medium method was R=0.99. When 1% Bif. longurn was inoculated on 12%, 14%, and 16% reconstituted skim-milk, viable cell counts were 8.60, 8.89, and 8.93 Log CFU/ml, respectively. When Lactose, Glucose, Glucosamine, Fructose, Peptone, N-acethyl-D-glucosamine, D-galactose, and liver extract were added to 16% reconstituted skim-milk, the viable cell counts were 8.61, 9.05, 9.15, 9.24, 8.82, 9.75, 9.17, and 9.64 Log CFU/ml, respectively. Therefore, D-galactose, liver extract, and N-acethyl-D-glucosamine were selected as final additives. When Bif longum was inoculated on Fermentor-I (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% D-galactose and 0.5% liver extract), Fermentor-II (16% reconstituted skim milk containing 0.190% yeast extract, 0.590% N-acethyl-D-glucosamine and 0.5% liver extract), Batch culture-I (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% D-galactose and 0.5% liver extract), and Batch culture-II (16% reconstituted skim milk containing 0.1% yeast extract, 0.5% N-acethyl-D-glucosamine and 0.5% liver extract), viable cell counts were 10.46, 9.37, 9.03, and 8.83 Log CFU/ml, respectively. Although liver extract was the important additive for the highly concentrated culture of Bif. longum in this study, it caused serious off-flavor when liver extract-1 (contained cell mass) was added to Fermentor culture. However, flavor was improved when liver extract-2 which was removed cell mass, was used instead of liver extract-1. Addition of 2% liver extract-II and 1% D-galactose had the similar effect with addition of 0.5% Liver extract-I and 0.5% D-galactose on the growth of Bif. longum.

A partitioned signature file is an enhancement of the signature file that divides all the signatures into blocks in such a way that each block contains the signatures with the same key. Its directory stores all the keys as meta information for avoiding unnecessary block accesses by examining them first before the actual searching of the blocks. Efficient directory management is very important in large database environments since its size gets larger proportionally to that of the database. In this paper, we first point out the problems in the directory management methods of the previous partitioned signature files, and then pressent a new one solving them. Our method offers good features in the following three aspects: (1) suitability for large database environments, (2)adaptability to dynamic situations, and (3) storage overhead for the directory.

PTMG-PU와 PEAG-PU의 중합에 미치는 합성온도 영향

류주환,김수동 忠南大學校 産業技術硏究所 1998 산업기술연구논문집 Vol.13 No.2

예비고분자 방법을 이용하여 PTMG-PU와 PEAG-PU를 합성하였다. PTMG-PU와 PEAG-PU에서 합성온도를 올림에 따라 가교결합 증가와 상분리 감소를 적외선 분광기를 이용하여 확인하였다. 또한 합성온도 상승의 영향은 DSC에 의해 확인되었다. 가교결합의 증가와 상분리의 감소는 PTMG-PU와 PEAG-PU의 유리전이 상승을 초래하였다. 적외선 분광기와 DSC로 확인한 중합온도 영향이 분자 구조적인 면에서 같다 할지라도 PTMG-PU와 PEAG-PU의 인장강도와 연신율은 반대로 나타났다. 이것은 가교밀도의 변화에 의한 것으로 고찰되었다. We synthesized PTMG-PU and PEAG-PU through prepolymer method. According to IR, we observed that as the reaction temperature increases, crosslinking density was increased and phase seperation was decreased in both cases of PTMG-PU and PEAG-PU. Also the synthesis temperature increasing effect was confirmed by DSC. Increase in crosslinking density and decrease in phase seperation resulted in the increase of glass transition temperature in both PTMG-PU and PEAG-PU. Althouth the synthesis temperature effect was the same in molecular structure variation, tensile and elongation properties of PTMG-PU and PEAG-PU were reverse. This was discussed in terms of the crosslinking density.
