The purpose of this study was to investigate the effects of detraining and retraining on serum lipid and hormones in soccer players. Subjects were seven male high-school soccer players. V˙O_2max was determined for each subjects by administering a treadmill test(initial speed: 90m/min, grade: 5%, increasing speed per 3 min: 30m/min). Serum lipid(T-C, TG, HDL-C LDL-C) and hormones(epinephrine, norepinephrine, growth hormones, cortisol) were assayed pre and post detraining in 10, 20, 30 days after retraining. The repeated ANOVA was used to determine significant differences. The 0.05 level of significance was as critical level for the study. The results of the study were as follows: 1. V˙O_2max(ml/min) were 3576.3±204.2ml/min pre detraining, 3234.1±198.9 ml/min post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/min) were 3601.4±170.9 ml/min. There were significantly(p<.05) increased in retraining periods. 2. V˙O_2max(ml/kg/min) were significantly(p<.05) decreased from 62.3±2.9 ml/kg/min to 55.9±4.7 ml/kg/min in detraining. In 10, 20, 30 days after retraining, V˙O_2max(ml/kg/min) were 62.4±3.4ml/kg/min, 62.7±2.3ml.kg/min, 67.3±7.2ml/kg/min respectively. There were significantly(p<.05) increased in retraining periods. 3. T-C were significantly (p<.05) increased from 166.6±8.5mg/dl to 175.3±10.3 mg/dl in detraining. In 10, 20, 30 days after retraining, T-C were 160.1± 3.2mg/dl, 156.7±3.7mg/dl, 140.3±9.0mg/dl. There were significantly(p<.05) decreased in retraining periods. 4. HDL-C were 61.4±6.6mg/di pre detraining, 5.3±6.6mg/dl post detraining. There are significant(p<.05) difference between pre and post detraining. In 10, 20, 30 days after retraining, HDL-C were 56.9±7.1mg/dl, 56.4±9.2mg/dl, 57.7±9.1mg/dl respectively. There were no significant difference in retraining periods. 5. The hormones(epinephrine. norepinephrine, growth hormone, cortisol) were changed as same patterns. Epinephrine were 26.0±7.0[g/ml pre detraining, 24.6±3.2pg/ml post detraining. In 10, 20, 30 days after retraining, epinephrine were 26.9±5.6pg/ml, 30.6±6.2pg/ml, 29.4±5.6pg/ml respectively. There were no significant difference in retraining periods. In conclusion, HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were decreased, T-C, LDL-C and TG were increased in detraining. But HDL-C, epinephrine, norepinephrine, growth hormone and cortisol were increased, T-C, LDL-C and TG were decreased in retraining.

Purposes of this study were 1) to identify the level of role expectation and role performance for school health educators as elementary school students recognize and to compare them, and 2) to examine differences in the role expectation and performance by characteristics of students and educators. Subjects of the study were 1,428 6th grade students at 37 elementary schools in Busan. The data were collected by a structured self-administered questionnaire, measuring role expectation and performance that students recognize. The data were analyzed with descriptive statistics, t-test, and ANOVA by SPSS program. The results were summarized a s follows. 1. Students' level of recognizing the role expectation was high(M=4.08) and level of the role performance was moderate to high(M=3.50) within rang of 1 to 5. The students recognized role expectation greater than role performance. 2. The students' point of view for role expectation and performance for school health educators were related to several characteristics of students and school health educators. Students' levels of recognizing the role expectation and performance were higher when students were male, healthy, their academic performance was high, their level of satisfaction with their school life was high, and their level of satisfaction with using school health office was high. With characteristics of school health educators, students' level of appreciating the role expectation was higher when educators were of an older age and had a long career, and when they were fairly satisfied with their job as an educator. Students' level of recognizing the role performance was higher when educators were of a younger age, and had a small number of students at school. This indicates that there exists role conflict on students and implies that the conflict need to be mediated, and desirable solutions to address the conflict need to be developed by school health educators.

DIS80의 遺傳子型 決定을 위한 PCR法의 條件에 관한 硏究
鄭宰安,黃迪駿,李羲碩,宋垠燮 大韓法醫學會 1994 대한법의학회지 Vol.18 No.1
The polymerase chain reaction(PCR) is known to be a very sensitive method of nucleic acid synthesis by which a particular segment of deoxyribonucleic acid(DNA) can be specifically amplified. However, as no single protocol will be appropriate to all situations, it requires to optimize the PCR conditions for a given application, especially analytical procedure to amplified fragment length polymorphism of VNTR region. Recently, typing of VNTR regions in the field of forensic science is almost done by PCR, but this reaction ofter results in a number of potential problems including generation of recombinant alleles during the extension phase. The objective of this paper is to evaluate the cause of PCR products of a abnormal length, and to set up the guideline for the reliable production of D1S80VNTR region in the human genome by studying several parameters that influence polymerase chain reaction. In the study of D1S80 VNTR region to be amplified, the following PCR conditions are optimal in the 50㎕ of reaction volume and under the temperature conditions of 95℃ for 1 minute, 65℃ for 2 minutes and 72℃ for 2 minutes. 1. The adequate concentration of MgCl₂ is within the range of 1.0 to 2.0 mM. 2. The high activities of Taq polymerase show about 0.5 to 1.5 units without generation of the undesired products. 3. The adequate amount of template DNA is about 30 to 50ng, although the template DNA can be amplified with the minimum of 40pg. 4. With the 50ng of template DNA, the adequate numbers of PCR cycle range 25 to 27 cycles. 5. Artifact production by PCR is minimal within the range of 0.2 to 0.3μM of each primer concentration. With the above conditions, amplified fragment length polymorphism (AMP FLP) obtained by polymerase chain reaction from the genomic DNAs of 4 Korean families (one family with 8 offsprings and both parents, 3 families composed of each one child and both parents) were analyzed to test the applicability of this technique to paternity testing. The results obtained present reliable parent child relationships based on the correct genotypes of D1S80, without any undesired PCR products of abnormal length that are postulated as heteroduplex resulting from cross annealing or hybridization between the amplified target DNA.

A 63 year-old woman who had diagnosis of multiple sclerosis complaining left hemiparesis and fluctuating decreased visual acuity in her right eye and abnormal findings in pattern shift visual evoked potentials(PSVEPs) and on T2 weighted MR scanning. We treated her subcutaneously with 250μg interferon (3-lb(ITFß -lb) every other day. There were detected pancytopenia, skin rash, and abnormal liver function test seven days after the therapy. In spite of reducing the dose of interferon injection, abnormal laboratory findings were not returned to normal. Dose adjustment of interferon-I3 for body weight or race, may be helpful to reduce the side effects.

남태석,정연국,최정은 한국관광정책학회 2000 觀光政策學硏究 Vol.6 No.3
Conventions have become extremely important in today's business world. Every fields has its conventions : Professions, trade unionism, education, arts, commerce, politics, and fraternalism all rely on conventions to bring together the membership's cross section of ideas. At past sutudies, there were few detailed studied for the PCO services in Korea even though they have taken several accesses to the international convention in the hardware aspect like facilities as well as in the software aspect. Whereas, for the activation of the international convention industry, this study shows how much the participant are satisfied with the service of the PCO, and then presents the way out of tough conditions of Korean tourism as holding more international convention, which invites quality foreign tourists in large number. Therefore the object of this study shall be of help to the desirable development of international convention industry through the survey of the satisfaction with the PCO service based on the positive investigation and the view of attendant. In a common view of domestic and foreign people, while Korean PCO comes up to the standard in the planning and working out the international convention, it cannot meet the various requirements of attendants in the specialized knowledge interpretation and relationship. Therefore it needs the new establishment of the developend and systmatic departure to bring up the specialized PCO.
