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.

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.

Background: Xenotransplantation is thought to be one of the alternative methods to overcome the shortage of human organs for transplantation. Recipients should be immunosuppressed for graft survival, and thus, there is a need for developing diagnostic modality that can detect diverse infections originating from animals and recipients rapidly, in the early stage, and with high sensitivity using small volume of samples. This study was carried out to develop a fast, simple, and robust technique for the preparation of HCMV DNA and PERV RNA using small volume of samples. Materials and Methods: Nucleic acids were extracted from serially diluted samples with one step extraction method as well as with Qiagen kit. The presence of genomic DNA of human cytomegalovirus (HCMV) and porcine endogenous retrovirus (PERV) was detected by PCR and specific primer set, respectively. RNA of HCMV and PERV was extracted and then detected by RT-PCR and specific primer set, respectively. For absolute quantification of HCMV, standard curve was established by real time PCR. Results: HCMV DNA and PERV RNA were prepared from culture supernatant and cells for PCR or RT-PCR with one step extraction method. It was possible to extract both the DNA and RNA from the samples in about 20 minutes with one step extraction method in a single tube. HCMV and PERV could also be detected by PCR and one step extraction method, respectively. It was also good with small quantity samples. Conclusions: One step extraction method is simpler and faster method than other extraction methods when there are two types of DNA and RNA viruses in one sample. From these results, we could see that the one step extraction method could be very useful in detecting HCMV and PERV rapidly from the pig cells or organ transplanted recipients with a small amount of sample.

Recently, lip-reading has become a hot topic in the field of multi-modal interface technology. Previous lip-reading systems work on some specific conditions. Especially, they can extract face region and lip region on some predefined conditions. Also, they support only off-line running environment. To overcome such problems, this paper proposes a technique which extracts face and lip region in real-time from the input video. Also, it proposes a method which extracts visual speech features from the lip region which can be used as input parameters to the HMM based recognition system. With the extracted visual speech features, our lip-reading system can execute training and recognition in real-time. Modified mean shift algorithm is then applied to detect and track the facial region from the facial region probability distribution. After finding face region, lip region is detected by finding the region which has minimum hue value distribution. Next, PCA(Princip1e Component Analysis) is applied to extract features data, and HMM (Hidden Markov Model) based pattern recognition is used to realize real-time training and recognition.

본 연구에서는 소비자-브랜드 관계(BRQ)가 확장된 브랜드 평가에 미치는 영향력을 알아보고, 또한 소비자-브랜드 관계의 강도에 따라 확장된 브랜드에 대한 평가시에 적정한 불일치성 효과(MIE)가 나타나는지 검증하고자 하였다. 연구 결과 소비자-브랜드 관계 강도에 따라 확장된 브랜드에 대한 태도와 구매의도는 다른 것으로 나타났으며, BRQ의 여섯 개 하위차원 중에서 확장된 브랜드 평가에 직접 영향을 미치는 것은 관계의 질 차원과 사랑과 열정 차원인 것으로 분석되었다. 한편, BRQ가 높은 집단에서 확장된 브랜드에 대한 적정한 불일치성 효과는 나타나지 않았으며 속성 유사성 효과도 나타나지 않았다. 반면 BRQ가 낮은 집단에서는 기존의 연구들과 마찬가지로 속성 유사성에 따라 확장된 브랜드에 대한 평가가 다른 것으로 분석되었다. 본 연구의 결과는 확장된 브랜드에 대한 평가에는 기존 브랜드와의 BRQ가 중요하며, 관계가 강할 때에는 속성 유사성 정도에 관계없이 확장 브랜드에 대해 호의적인 평가가 일어날 수 있음을 시사하고 있다. We examined how consumer-brand relationship affects the evaluation of extended brands. Specifically, we investigated the effect of the sub-dimensions of consumer- brand relationship quality (BRQ) on the evaluation of extended brands and the existence of moderate incongruity effect (MIE) in high BRQ consumers. The results shows that the BRQ sub-dimensions have different effects to the attitude toward the extended brand and purchase intention to the extended brands. We tested MIE in high BRQ consumers, the result did not support of moderate incongruity effect in brand extension. It means that strong BRQ consumers evaluate positive to the extended brands regardless of the degrees of the product attribute similarities. For the weak BRQ consumers, the product attribute similarities with parent brands affect their attitudes and purchase intentions of extended brands in the same result of the previous study. These results showed that the strong consumer-brand relationship is key important factor to the favorable evaluations to the brand extensions. Finally, theoretical and practical implications and limitations of this study were discussed.

ABSTRACT - This study was performed to evaluate hepatoprotective effect of daewhang-whangryunhaedok-Tang(DWT) on liver injured rats induced by CCI_4 and the acute oral toxicity of it in mice. The activities of serum transaminase(ALT/AST), alkaline phosphatase(ALP) and lactic dehydrogenase(LDH), the levels of serum total cholesterol(TC) and triglyceride(TG), change of liver enlargement, and inhibitory activities of lipid perotidation, catalase and glutathione-S-transfrease(GST) in liver microsome were determined in hepatotoxic rats induced by CCI_4. DWT was significantly reduced the serum ALT, AST, ALP, LDH. TC and TG lecels. And, the increase of lipid peroxidation, decrease of catalase and GST activities in the liver microsome of CCI_4-intoxicated rat were significantly improved by the treatment of DWT. Male and female mice were administered maximum dosages of 5.000 mg/kg b.w. of DWT. After single oral administration of DWT to mice, we observed them daily for 2 weeks.DWT did not induce any toxic signs in the mortalitie, clinical signs, body weight changes, and gross necropsy finfings of mice. Based in these results. It is concluded that DWT may have the hepatoprotective effect on CCI_4 induced hepatotoxicity in rats. Also. DWT may have no side effect and its LD_50 value may be over 5.000mg/kg b.w. in mice.
