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.

연골육종은 비교적 서서히 자라며 늦게 전이하는 악성 연골 종양으로 알려져 있다. 골 연골종에서 발생한 속발성 연골육종은 발생빈도는 드물며 타부위로의 전이가 적고 악성도가 낮은 경우가 많아 적합한 수술적 치료로서 좋은 예후를 보이는 것으로 보고되고 있다. 본 동국대학교 정형외과학 교실에서는 우측 대퇴골 원위부 골간단부에 생긴 고립성 골 연골종에서 이차적으로 발생한 연골육종을 치험한 바 문헌고찰과 함께 보고하는 바이다. A case of Secondary Chondrosarcoma Arising from Solitary Osteochondroma of the Distal Femur Department of Orthopaedic Surgery, College of Medicine, DongGuk University Phil Hyun Chung M.D., Jung Su Hwang M.D., Suk Kang M.D., Yang Mln Kim M.D., Hyung Ho Oh M.D., Dong Ju Chae M.D., Jong Pil Kim M.D. Chondrpsarcoma is a malignant cartilage-forming tumor that grows slowly and metastasis of this tumor occurs in late stage. Secondary chondrosarcomas arising from a solitary osteocartilaginous exostosis are rare and those have a better prognosis than other chondrosarcomas, and they rarely metastasize. We present our experience with a case of secondary chondrpsarcoma arising in solitary osteochondroma of distal metaphysis of right femur with clinical details.

Objectives : Abnormalities of cognitive responses to verbal and visual distracter in schizophrenia have been demonstrated in numerous studies but little is known about three dimensional visuospatial-motor distracter processing. The purpose of this study was to investigate the vulnerability of patients with schizophrenia to three dimensional visuospatial-motor distracter. Methods : 14 patients with schizophrenia and 14 normal volunteers were assessed on three dimensional maze tasks requiring on working memory and reasoning ability in the virtual reality environment. Performances were compared according to with- or without-distracter conditions. Results : Patients with schizophrenia showed significantly lower performances than normal control group on cognitive flexibility, simple motor function or motor control and motor coordination, working memory span and delayed performance times. The performance index tended to be more deteriorated, but not significantly, in with-distracter condition than in Without-distracter condition in schizophrenia. Conclusions : Patients with schizophrenia tend to be vulnerable to visuospatial-motor distracter which simulate the real world of three dimensional environment.

본 연구는 전보(정 등, 2002)에서 제조된 직물유리섬유 강화집성재의 박리 및 수분 흡착특성을 조사해 보기 위해서 실시되었다. 침지 박리시험에서, 3가지 형태의 소재 모두 박리를 나타내지 않았지만, control재를 제외한 모든 형태의 소재는 삵음 박리에서 박리가 발생하였다. 수분흡착시험은 40℃, 상대습도 90%조건에서 48시간동안 실시하였다. 횡단면 흡습성은 모든 소재에서 다르지 않았다. 유리섬유로 된 소재에서 방사단면과 접선단면은 control재와 비교하여 수분 흡착이 지연되었다. 수분흡착 이방성에서, 유리섬유 함입된 소재는 적은 수분흡착을 나타내었다. This study was conducted to estimate peeling and vapor adsorption properties made with fabric glass fiber reinforced laminated timber according to our earlier report(Jung et al., 2002). In adsorption peeling test, three all types solid wood were not appeared the peeling. However, solid wood appeared to the peeling in boiling peeling test except for control wood. Vapor adsorption test was performed at 40℃, 90% relative humidity for 48 hours. Cross sections were not different all solid wood. Radial section and tangential section with glass fiber were delayed vapor adsorption compared to control wood. In anisotropy of vapor adsoption, solid wood with glass fiber were small values.

Transthyretin의 Glutathione 자동산화 촉진작용

박종근,정신,김재휴,김수한,강삼석,이제혁,안봉환 대한신경외과학회 1994 Journal of Korean neurosurgical society Vol.23 No.8

When reduced glutathione(GSH) was incubated at neutral pH and at 37°, its concentration decreased slowly with formation of oxidized glutathione(GSSG). Autooxidation of GSH was accelerated by Cu^(2+) and Hg^(2+), but not by other common mono-, di-, and tri-valent cations. Transthyretin was found to stimulate autooxidation of GSH in the presence or absence of Cu^(2+) and Hg^(2+). EDTA inhibited perfectly the autooxidation of GSH regardless of the presence of transthyretin. The stimulating activity of transthyretin was maximal at pH 7.0, declining progressively with increase or decrease of pH from 7.0. Sulfhydryl-blocking agents such as p-hydroxymercuribenzoic acid and Nethylmaleimide markedly inhibited the stimulating activity of transthyretin. Transthyretin stimulated autooxidation of other sulfhydryl compounds such as clithiothreitol and cysteine. However, it did not show a significant effect on autooxidation of sulfhydryl group of egg albumin and eye lens proteins. And transthyretin did not cause any oxidative change to thyroxine(T₄), 3, 5, 3Ltri iodo thyronine(T₃) and 3, 3: 5~triiodothpnine(rT₃) bound to it in the presence of GSH and Cu^(2+). The above results suggest that transthyretin may play a role in regulation of oxidized status of sulfhydryl groups in blood plasma and cerebrospinal fluid

In recent years, shearogrpahy has significantly improved capabilities in the areas of unbond and separation detection in tires. Although shearography has many advantages for qualitative evaluation, the technique remains the problem of quantitative analysis of inside defects, because shearography needs several effective factors including the amount of shearing, shearing direction and induced load, which exist as barrier for the quantitative analysis of inside defects. In this study, the factors were optimized and the size of cracks inside of tire has been quantitatively determined. Since the factors are highly dependent on inspectors skill and also affect the in-situ workability.

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.

예종석,이은정,김균 한국방송광고공사 2005 광고연구 Vol.0 No.69

소비자 의사 결정과정에 대한 정보를 제공하는 커뮤니케이션은 마케팅이나 광고전략에 있어서 중요한 역할을 한다. 다양한 마케팅 커뮤니케이션 도구들이 개발되면서 마케터들은 과다한 정보를 제공하게 되었고 제한된 소비자들의 관심을 끌기 위해 수많은 사람들과의 경쟁에 합류하게 되었다. 이에 대한 해결책의 일환으로 불일치한 광고에 대한 연구가 진행되었다. 따라서 본 연구에서는 제품을 구매의도에 따라 쾌락적 제품과 실용적 제품으로 분류하고 광고의 불일치성이 각 제품유형에 미치는 영향을 비교 평가하였다. 연구결과 기대·관련 - 비기대·관련 광고의 광고평가에 대한 차이에서는 느낌, 공감, 신뢰, 제품 평가에 대한 도움이 제품별 차이가 유의한 것으로 나타났으며, 기대·관련 - 기대·비관련 광고의 광고평가에 대한 차이에서는 신뢰, 유익, 제품평가에 대한 도움이 제품별 차이가 있는 것으로 나타났다. 또한 기대·관련 - 비기대·비관련 광고의 광고평가에 대한 차이에서는 느낌, 공감, 설득이 제품별 차이가 있는 것으로 나타났다. 본 연구는 이와 같이 태도와 설득에 관한 연구에 기초하여 광고의 불일치성을 기대성과 관련성이라는 개념으로 구분하여 소비자들이 느끼는 광고와 제품평가, 구매의도를 실증적으로 연구하였다. 또한 태도의 다중 구성 요소 이론을 제품의 구매동기에 따른 제품형태로 확장하여 새로운 영역의 발전을 시도하였으며, 서로 다른 불일치 차원에서 소비자들의 반응의 차이를 구하여 제품별로 비교 평가하였다. The purpose of this study is to classify products into hedonic products and utilitarian products by intention to purchase, and to compare and evaluate effects of inconsistency of advertisement on product types. The results of this study shown that concerning the expectation and the relevance of advertisement, there was significant difference in the advertisement evaluation, product evaluation, and intention to purchase partially. This study can be considered to be significant academically in terms of classifying inconsistency of advertisement into “expected” and “relevant” and examining customers’ response against advertisement, product evaluation, and intention to purchase empirically on the basis of studies on attitude and persuasion. And, this study had academic significance as it was attempted to develop the new field of studies by extending multi components theory of customers’ attitude into product type by purchase motive of products, and to examine difference in consumers’ response in different level of inconsistency and to compare and evaluate by products.

Background: High risks of fire alway exist for buildings in urban areas, especially those in downtown. Crowds, as well as more complex and larger structures, may cause more victims in the event of fire; therefore, emergency medical service plans must be established for such disastrous events. Methods: On the evening of October 30,1999, a fire broke out in downtown, Dong-Incheon Live-Hof restaurant; 56 people were killed and 76 were injured. Most of them were teenagers. We retrospectively reviewed the medical records of the victims, Results: 1) Among the 56 dead, 54 died from smoke inhalation, one from extensive burns, and one from sepsis during treatment. 2) Among the 76 injured, 70 patients suffered from smoke inhalation, 53 from burns, and 9 from several types of trauma (sprains, contusions, lacerations, abrasions, fractures, etc.). 3) Later complications were laryngeal edema, pulmonary edema, scar contracture, and hypoxic brain damage, and so forth. 4) Post traumatic stress syndrome was unexpectedly more prevalent in mildly to moderately injured survivors and witnesses than in seriously injured survivors. Conclusion: Many complications exist after a fire. Some may be resolved in time, but others may result in permanent sequelae. Early rescue, early triage, and early management during transport by emergency medical service (EMS) personnel can result in fewer complications and a lower mortality rate. Therefore, we propose the establishment of plans to be followed during various major disasters.
