The object of this study is to provide base data of more effective utilization of traditional play songs through analyzing the effect of group activities using traditional play songs on young children's interpersonal problem thinking. For this purpose, we selected two kindergartens in Daejeon and prepared control and experimental groups with 31 of 4-5 year-olds in each group. For the experimental group, we had conducted group activities using traditional play song for 12 weeks. As a result, the experimental group's score of interpersonal problem thinking area was higher than that of control group. Therefore it is obvious that group activities using traditional play songs give positive effect to the thinking of alternative problem solving and prediction of consequence which are sub-capabilities of interpersonal problem thinking. In this study, we set problems and hypothesis as followings to investigate the effect of the group activities using traditional play songs on young child's thinking of alternative problem solving: 1. Do the activities using traditional play songs give effect to the capability of interpersonal problem solving of young child? 2. Do the activities using traditional play songs give effect to the thinking of alternative problem solving of young child? 2-1 There would be meaningful difference between two groups in thinking of alternative problem solving. 2-2 There would be meaningful difference between two groups in positive alternative solution of the problem. 3. Do the activities using traditional play songs give effect to the thinking of consequence prediction of young child? 3-1 There would be meaningful difference between two groups in the thinking of consequence prediction. 3-2 There would be meaningful difference between two groups in the method of consequence prediction.

Background and Objectives : Brain death may lead to hormonal depletion, metabolic derangement and multiple organ dysfunction. We have carried out present study to examine the effects of brain death on the thyroid function, metabolic indices, and the severity scoring systems. Methods : 13 adults patients admitted for organ donation or brain death evaluation were examined after brain death was confirmed. Thyroid hormones measured were .thyroid stimulating hormone (TSH), triiodothyronine (T3), thyroxine (T4), and free thyroxine (FT4). The metabolic indices measured were arterial ketone body ratio (AKBR), lactic acid (LA), and base defiat (BD). as for reference to the severity scoring systems, APACHE Ⅲ and multiple organ failure score (MOFS) were assessed on the day of brain death confirmation. Arterial blood was drawn for all measurements. Results : As for the thyroid function, there were significant decreases in T3 (40.48±20.96 ng/dL) and T4 (3.47±2.15 ㎍/dL), but no significant change in FT4 (0.75±0.31 ng/dL) and TSH (1.12±1.37 uIU/mL) compared to the normal range. Significant decreases in AKBR (0.39±0.31) and BD (-9.46±5.83 m㏖/L), and significant increase in LA (2.57±2.46 m㏖/L) In metabolic indices, were shown, as for severity scoring systems, APACHE Ⅲ score (101.54±19.41) and MOF score (9.11±2.57) indicated a high mortality. There were significant correlation between thyroid hormones (r=0.565 -0.781) but no correlation among other indices. Also, significant inverse correlations were shown between base deficit and lactic acid (r=-0.660), APACHE Ⅲ score (r=-0.726) and MOF score (r=-0.604). The highest correlation was observed between APACHE Ⅲ score and MOF score (r=0.851). Conclusions : As for the thyroid function, significant decrease in T3 and T4, and almost normal range of FT4 and TSH imply the euthyroid sick syndrome. Abnormal finding of the metabolic parameters indicates an inhibition of the aerobic metabolic rate of the body as a whole. And the severity scoring parameters are compatible with high mortality.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

Agrobacterium tumefaciens의 Ti plasmid 재조합에 관한 연구

주충노,이희봉,김영명 연세대학교 자연과학연구소 1987 學術論文集 Vol.19 No.-

Crown gall의 병원체로 알려진 Agrobacterium tumefaciens가 함유하고 있는 Tumor inducing(Ti) plasmid가 식물 hormone과 opine의 합성원인이라는 것이 밝혀지고 식물 세포의 crown gall에는 Ti plasmid가 존재하며 Ti plasmid의 일부가 식물세포의 핵 genome에 삽입되어 형질 변화가 일어남이 보고 되었고 Ti plasmid의 식물체로의 gene도입 vector로서의 연구가 최근 활발히 진행되고 있으며 현재 PLGV vector와 PMON vector 등이 개발되고 있으나 조작이 복잡하고 아직은 초보적 단계인 것으로 알려져 있다. 본 연구에서는 원하는 식물 gene을 식물체에 도입하는 유용한 vector개발의 초보단계로서 Ti plasmid의 T-DNA의 일부인 nos gene을 분리하여 pBR322와의 재조합을 기도한 것이다. pBR 322를 포함하는 E. coli로 부터 Horwitz(1979)의 방법으로 pBR 322를 분리하였고 A. tumefaciens C58에서 Kado(1979)의 방법으로 Ti plasmid를 분리한 후 Ti plasmid 내의 nos gene을 분리하였다. 분리된 pBR 322를 Hind Ⅲ로 절단한 후 CIP로 처리하고 T_4 DNA ligase를 이용하여 Hind Ⅲ로 처리한 nos gene fragment와 재조합하였다. 이와같이 하여 얻은 recombinant DNA로 인한 E. coli HB101의 형질 변화를 Mandel과 Higa의 방법에 따라 조사한 결과 pBR 322의 tetracyclin gene 사이에 nos gene이 삽입된 것으로 확인되었다. 즉 ampicillin 배지에서는 92개의 colony가 형성되었는데 그중 59개는 tetracyclin 배지에서 colony를 형성하지 못하였다. 이러한 tetracyclin 감수성이면서 ampicillin 저항성인 colony를 배양하여 얻은 recombinant plasmid를 전기이동법으로 분리한 결과 예상대로 크기가 7.5kb 정도였고 Hind Ⅲ로 절단하였을 때 2개의 band가 확인되었다. 본 연구에서 얻은 nos gene-pBR 322 hybrid plasmid는 원하는 식물 gene을 이것에 삽입하여 A. tumefaciens 내에서 homologous recombination을 행한 후 식물체에 감염시켜 원하는 gene의 발현여부를 검출하는데 이용될 것으로 기대된다. It is mow realized that the tumor-inducing(Ti) plasmid in Agrobacterium tumefaciens is responsible for the induction of crown gall tumors in dicotyledonous plants and it has been demonstrated that a segment of the Ti plasmid, so called T-DNA, is stably integrated into and expressed in the genome of transformed plant cells. Recently, the use of A. tumefaciens Ti plasmid as a vector to introduce a foreign gene has been intensively studied and several vectors such as PLGV vector and PMON vector has been reported. However, their practical use is still at a primitive stage. It was attempted in the present study, therefore, to conduct the recombination of nos gene of T-DNA from A. tumefaciens Ti plasmid and E. coli pBR 322 as a vector it introduce foreign plant gene into dicotyledon plant cells. pBR 322 was isolated from E. coli containing pBR 322 accdrding to Horowitz(1979) and nos gene of T-DNA in Ti plasmid from A. tumefaciens C58 was obtained according to Kado(1979). The isolated pBR 322 was cut using Hind Ⅲ followed by the addition of CIP·pBR 322 fragments and Hind Ⅲ treated nos gene fragments were than recombined using T_4 DNA ligase and the E. coli cells were then transformed by recombinant DNA according to Mandel and Higa(1970). It was confirmed that nos gene was inserted into tetracyclin gene of pBR 322 by the finding that when the transformed cells were incubated in the ampicillin medium, 92 colonies were formed, in which 59 were tetracyclin sensitive. The above tetracyclin sensitive but ampicillin resistant cells were then cultured and the recombinant pBR-nos gene was isolated and subjected to electrophoresis. It was found that size of the recombinant DNA was approximately 7.5 Kb as expected and two bands were appeared on electrophoretogram when the recombinant DNA was treated with Hind Ⅲ. It might be possible to insert the foreign plant genes to the pBR-nos gene hybrid plasmid obtained in the present study and the resultant DNA could be then homolgously recombined with Ti plasmid of A. tumefaciens and the final recombined Ti plasmid could be used for the introduction of the foreign plant genes into dicotyledon plant cells.
