The purpose of this examination was to find out the relationship among secondary school learners' academic/nonacademic self-concept, school-related attitudes and school-related coping. And in order to achieve the purpose of this examination sampled middle/high school learners in Seoul and other areas. The instruments used for the data collection were 「Self-Concept Scale」 (Kim, Yong-Rae, 1995), 「School-Related Attitudes Scale」 (Kim, Yong-Rea, Lee, Hye-Won, 1996) and 「School-Related Coping Scale」 (Kim, Yong-Rae, 2000). The collected data analyses were performed using SPSS Win (10 V) program, and analysed Mean score (M), Standard Deviation (SD), Zero-Order Correlation (γ) and Multi-Regression Analysis. All statistic values were tested by t-test and F-test in the significant level of p< .05. And as for the major findings of this examination, only three variables - 'school general self-concept', 'teacher-related attitudes' and 'instruction related attitudes' among all research variables for this examination were significantly positive influences on Korea secondary school learners' "school-related coping" respectively.

엄태현,조종래 인제대학교 백병원 2002 仁濟醫學 Vol.23 No.3

Objectives: There have been debates on the relationship between ABO blood groups and infectious diseases. It is known that blood type A has the tendency to have staphylococcus aureus bacteremia. We investigated this relationship in Koreans. Methods and Materials: We analysed the ABO blood groups in the bacteremia patients in Ilsan Paik hospital, from January 2000 to March 2001. The number of patients with S. aureus bacteremia is 30, coagulase negative Staphylococcus(CNS) 40, Escherichia coli 21, and blood culture negatives(BN) 104. We used the distribution of ABO blood groups of 1,018 patients as the control, for whom ABO blood typings were done in blood bank during December 2000. Results: The frequencies of blood group A, B, O and AB in blood bank controls were 32%, 28%, 28%, and 13%, respectively. For S. aureus bacteremia, they were 20%, 43%, 20%, and 17%; for CNS, 45%, 35%, 15%, and 5%; for E. coli, 24%, 24%, 43%, and 10%, respectively. For BN, they were 35%, 27%, 23%, and 15%, respectively. There were no statistically significant differences in ABO blood groups between control and each bacteremia including BN. But there was the tendency that CNS group had higher frequency of blood type A and lower frequency of blood type O. Conclusions: We concluded that there is no significant relationship between ABO blood groups and bacteremia, but can not deny its presence because of the room for further studios.

This experiment was conducted to observe the effect of subatmospheric pressure storage on the coloration of tomato fruits. Tomato fruits(Lycopersicon esculentum Kang Lyuk Misu), which were cultured on field, were havested at the mature green stage on June 16, 1976 and stored 10℃ under normal atmospheric pressure (NAP) and sub-atmospheric pressure (SAP). Furthermore, the treatment at SAP was subdivided into CO_(2) 0%(SAP-O), CO_(2) 5% (SAP-5) and CO_(2) 10%(SAP-10) concentration, respectively. The results obtained were as follows : The chlorophyll content was rapidly decreased for 10 days, whereas the content of chlorophyll in SAP treatment was retained 2㎎% after 40 days. The lycopene content in NAP-5 was 5㎎% after 20 days. On the other hand, that in SAP-10 was 3㎎% art after 40 days. The red color development was retarded for 30 days in SAP-10. Comparing with the formation of lycopene, that of carotene was less inhibited by storage conditions (carbon dioxide, temperature, pressure) and increased more slightly in SAP than in NAP. The ripening of tomato fruits in NAP was retarded for about 30 days as compared that in SAP. The intensity of respiration in SAP was weaker than that in NAP. Also the peak of respiration in SAP was delayed compared to that of NAP. The content of reducing sugar and titratable acidity in SAP were retained more than in NAP up to 30 days tested.

최근 분류학은 형태형질 분석을 중시하는 전통분류기법과 함께 염기서열의 유전적 변이를 분석하는 분자분류학이 발달하고 있다. 최근에는 유전적 변이를 측정하기 위해 주로 종과 속의 분화에 따른 다양성을 나타내는 미토콘드리아 16S rDNA 서열을 이용한다. 이 실험은 부산에서 채집된 애반딧불이와 파파리반딧불이의 미토콘드리아 16S rDNA의 서열을 중합효소연쇄반응(PCR)으로 증폭한 후에 클로닝하고 서열을 분석하여 GeneBank에 보고된 유사종의 서열들과 비교하여 계통도를 도출하는 기준방법을 개발한 결과를 정리하였다. Contemporary taxonomy has been led to molecular taxonomy anyzing genetic variation of gene sequences with traditional taxonomy emphasizing morphological characters. Recently to measure genetic variation, it has been investigated the mitochondrial 16S rDNA sequences implying divergence of species and genera. This is the result obtained by comparing mt 16S rDNA of Lucidia lateralis Motschulsky and Hotaria papariensis Doi sampled in Busan Metropolitan City with the other firefly species registered in GeneBank.

Background: The purpose of this study was to determine the effectiveness of percutaneously place self-expanding metallic stent for the relief of biliary obstruction in patients with hilar cholangiocarcinoma. Materials and Methods: From November 2001 to December 2004, 48 patients with hilar cholangiocarcinoma were prospectively studied. After percutaneous placement of bilateral self-expanding, uncovered metallic stents, follow-up evaluation was carried out until July 2005. Results: There were 4 cased of Bismuth type Ⅱ,21 cases of Bismuth typeⅢa 8 cases of Bismuth type Ⅲb and 15 cases of Bismuth type Ⅳ. Stent placement was technically successful in all patients All patients had satisfactory biliary drainage, resulting in one week drainage rate of 72.8% and final drainage of 91.9% There were 12 cases (21.3%) of abdominal pain requiring analgesics and 1 case (7.1%) of cholangitis; both were successfully managed with conservative treatments. Late complications occurred in four patient (8.3%), including two patients with cholangitis, one patient with liver abscess, and one patient with biloma; all were appropriately managed by percutaneous drainage. The average length and median durations of stent patency and median survival time were 303 days (range, 60~815) and 338 days (range, 60 ~1175), respectively. Conclusion: Placement of a percutaneous metallic stent is an effective and safe method of palliation of patients with hilar cholangiocarcinoma.

This study was to determine the fiber-type populations and calculate the cross-sectional areas in each fiber-type in the muscle of the brachium of the rat. For 20 rats, the flexors (brachialis and biceps brachii) and extensors (triceps brachii) of the elbow taken from dissection. The fibers were classfied histochemically as fast-twitch oxidative glycolytic fiber(FOG), fast-twitch glycolytic fiber (FG), or slow-twitch oxidative fiber(SO), and their populations were determined. The cross-sectional areas of each type muscle fibers were calculated with microcomputer image analyzer. The results were as follows ; I. The variations in fiber-type population of various muscles with which their positions were observed as well as those reported in ot4er studies. 2. In both extensor and flexor groups, the deep region of the muscles was consisted of higher populaions of SO fibers, while more superficial regions of the same muscles were more FG fibers. 3. The percentage of SO fibers were larger in the extensors than that of flexors. 4. Except the SO fibers, the cross-sectional areas of FOG and FG fibers in the extensors were larger than that of flexors.

In this paper, the pole placement design theory is applied to position control system of DC servo motor. The DC servo motor is modelled by second order linear time invariant system. We assume that All state variables are measurable and are available for feedback. If the system considered is completely state controllable, then poles of the close-loop system may be placed at any desired locations by means of state feedback through an appropriate state feedback gain matrix K. This design method called the pole placement. Proposed pole placement design has superior performance in unit step response. The pole placement design theory is very useful to drive the position control system of DC servo motor.
