A study on the personality traits of the contacting and non-contacting game players has been made by administering a test of standardization on the players of judo, rugby, soccerball, gymnastics, volley ball, athletics and shooting. The result of the test turned out as follows: 1. On the general point of view, the players of soccer-ball (contacting sports) and those of athletics(non-contacting sports)have the meaningfully high points on all the aspects of the personality traits except on the aspect of impulse. 2. The players of gymnastics and shooting have higher points of stability campared with the players of the other sports owing to the optimistic personality traits of their general lives. 3. While the players of rugby (contacting sports) have the low points on the aspects of impulse and sociality unlike the original expectation, the players of athletics(contacting sports) have much higher points than those of players of soccer-ball, rugby, and judo (non-contacting sports) on the aspect of consideration. 4. On the aspect of sociality, the players of soccer-ball (contacting sports) have very high points compared with those of the other sports owing to the cooperation of their life in a group.

For more effective intraperitoneal chemotherapy, the authers made 5-fluorouracil-polyglycolic acid composite disks(FU-PGA disks) with 5-fluorouracil and polyglycolic acid, a biodegradable polymer. We inserted the FU-PGA disk into the peritoneal cavites of Sprague-Dawley male rats, the control and three experimental groups; one FU-PGA disk insert group(300mg/kg), two FU-PGA disk insert group(600mg/kg), and three FU-PGA disk insert group(900mg/kg). The control group received a similar number of PGA disk inserts. A pharmacokinetic study was performed to measure the 5-fluorouracil concentration in the peritoneal fluid, blood, and tissues(liver, kidney and heart) at 24 hours, 72hours and 168 hours after insertion of the FU-PGA disk. Light and electron microscopic studies were done. The results were as follows: 1) The number of white blood cells and platelets decreased after FU-PGA insertion. The degree was proportional to the duration and amounts inserted. The change in the number of red blood cells varied slightly. 2) Light microscopically, slight changes were noted at 168 hours in the 3 disk insert group (900mg/kg). Mild fatty change and hepatocyte degeneration around the central veins of the liver were noted, with vacuolar degeneration in the proximal convoluted tubules of the kidney. 3) Electron microscopically,the liver showed focal increases of lipid droplets in the hepatocytes, and irregular nuclear membrane with focal nucleolar segregation of the fibrillar and granular elements. Also the double membranous structure of the hepatocytes and Kupffer cells was widened with bleb formation. The kidney showed wide separation of the nuclear double membrane in the proximal convoluted tubular cells and mesangial cells, with vacuolation and myelin figure formation in the mitochondria of the proximal convoluted tubular cells, at 72 hours and 168 hours in the 2 to 3 FU-PGA insert groups. The heart showed focal loss of cristae,vacuolation and myelin figure formation in the mitochondria of the 2 to 3 FU-PGA insert groups. In conclusion, despite the large amont of FU-PGA inserted, the histopathological changes in the liver, kidney and heart were slight, and consonant with the very low amount of 5-fluorouracil concentrations detected in the liver, kidney and heart. The above results suggest that the FU-PGA composite can serve as a new device for releasing drugs in a controlled manner and easily targeted to intraperitoneal organs. This device can improve the efficacy of intraperitoneal chemotherapy for gastric cancer.

To decrease the acid quantity of the plum wine, we have treated the plum wine aged 3 months with calcium carbonate and potassium bicarbonat as antacids. Total acid contents of plum wine was drastically reduced and the pH was increased, rel-atively to concentrations, in the calcium carbonate treated group. But there was not consistent with results in the potassium bicarbonate treated group. However, Both of antacids did not affect the contents of total phenolics. Color changes were mon-itored by the CIELAB space, using the D65 illuminent and 10° observer. Redness (a) was significantly decreased in the plum wine treated with antacids. The chroma(C) and hue (H) parameters was also changed as a result of the dis-coloring process since they are combinations of the a and b parameters.

Vibration analysis of through-the-width-split beams for predicting buckling load is investigated based on Euler-Bernoulli beam theory. In split region, each segment is considered as a solid beam. In this region, recurrence equations relating integration constants for adjacent interior regions are established by satisfying continuity conditions at junctions of interior regions. The results of present study are compared with those of experiment and their results give good agreement with each other. From the result, it was shown that local buckling phenomena could appear in fundamental mode, however, there exists load carrying capacity after this phenomena.

강지현,유병연 대한비만학회 2003 The Korean journal of obesity Vol.12 No.2

연구배경: 최근 단순 비만 지표로서의 목둘레의 유용성에 대한 연구들이 발표되고 있으나 국내에서는 아직 목둘레와 심혈관계 위험인자와의 관련성에 대한 연구가 없었다. 이에 한국 성인 남녀에서 목둘레와 심혈관계 위험인자들과의 연관성을 알아보고 체질량 지수. 허리둘레, 체지방률 등과 비만 지표로서의 목둘레의 유용성을 비교해보기 위하여 본 연구를 시행하였다. 방법: 일개 대학 병원 종합 검진 센터에 내원한 남녀 292명을 대상으로 목둘fp와 심혈관계 위험인자와의 상관관차를 알아보고 목둘fp를 4분위 (quartiles)로 나누어 가장 낮은 목둘레 4분위군과 가장 높은 목둘레 4분위군 간 심혈관계 질환들의 교차비 (odds ratio)를 로지스틱 회귀분석을 통하여 구해 보았다. 체질량 지수. 허리둘레, 체지방률 등과 비교하여 목둘레가 독립적으로 심혈관계 위험인자들을 설명할 수 있는 변수인지를 단계별 다중 회기 분석 (stepwise multiple regression analysis)을 통하여 비교하였다. 결과: 목둘레는 남자에서 수축기 혈압 및 요산, 여자에서 이완기 혈압. 총콜레스데롤 및 저밀도 콜레스테롤을 제외한 심혈관계 위험인자들과 유의한 상관관차를 보였으며, 가장 높은 목둘레 사분위군에서 가장 낮은 목둘레 사분위군에 비해 HOMA score는 남자 29.2배, 여자 5.1배 증가하였곤, hsCRP는 남자2.0배, 여자 6.6배 증가하는 것으로 나타났다 단계별 다중 회기 분석에서 목둘레는 다른 비만 지표들에 독립적으로 남자에서는 이완기 혈압. 혈당, 총 콜레스테롤, 저밀도 콜레스테롤, 중성지방, 공복시 인슐린, HOMA score, 여자에서는 공복시 혈당, 고밀도 콜레스테롤, 공복시 인슐린 HOMA score의 변화에 기여하는 것으로 나타났다. 결론: 목둘레는 인슐린 저항성 및 hsCRP의 상승과 관련된 심혈관계 위험인자들과 연관되어 있으며 심혈관계 질환의 위험이 증가되어 있는 비만 환자의 선별 검사로 유용하게 쓰일 수 있을 것으로 생각된다. Backgrounds: The aim of the present study was to test the association of neck circumfernce with the cardiovascular risk factors. Methods: We examined 292 persons, who visited a health examination center. The correlation between neck circumference and other cardiovascular risk factors was tested, and the odds ratio was calculated for various cardiovascular risk factors in the highest quartile of neck circumference compared to lowest. We used stepwise multiple regression to find out whether the neck circumference could be the independent variable to other obesity indices for cardiovascular risk factors. Results: Neck circumference was significantly correlated with the cardiovascular risk factors except diastolic blood pressure, uric acid in men and systolic blood pressure, total and LDL cholesterol in women. This odds ratio for HOMA score in the highest quartile of neck circumference compared to lowest was 29.2 in men, 5.1 in women, and for hsCRP the odds ratios was 2.0 in men, 6.6 in women. In stepwise multiple regression, neck circumference accounted for diastolic blood pressure, total and LDL cholesterol, triglyceride, insulin, HOMA score in men, glucose, HDL cholesterol insulin, HOMA score in women independently to other obesity indices. Conclusion: Neck circumference is associated with the cardiovascular risk factors related to insulin resistance and hsCRP. The measurement of neck circumference could be useful in clinical screening for obese person at an enhanced risk for cardiovascular diseases.

말기신부전 환자에서 혈액투석 전후의 QT간격분산 비교

Background: Some cases of QT interval, corrected QT interval (QTc), QT dispersion (QTd) and corrected QT dispersion (QTcd) have been reported in ESRD, but these results are variable and the influence of a hemodialysis is still controversial, In this study, we investigated the effect of hemodialysis on QT and QTc interval and QT and QTc dispersion in patients with ESRD 15 min before and 15 minute after each hemodialysis. Methods: Sixty-seven patients with ESRD (men 33 & women 34) on three-times stable hemodialysis (>3 months) were randomly enrolled. Fifty control subjects with a similar age and normal renal function were enrolled from this hospital. Routine biochemical studies were measured pre- and post dialysis, at the time of the ECG. Plasma Na+, K+, BUN, creatinine, ionized calcium and phosphate were checked. Twelve-lead electrocardiographs were performed at 10㎜/mv and 50㎜/s using a HewIett-Packard Pagewriter 100, before and after a single hemodialysis session.The QT interval was measured from the onset of the QRS complex to the end of the T wave. If the end of the T wave was not clear in a particular lead then it was excluded from analysis. When U waves were present, the end of the T wave was taken as the nadir between the T and U waves. Each QT interval was corrected for heart rate using Bazett's formula (QTc==QT/√(RR)) (ms). The difference between maximal and minimal QT interval duration was defined as QT dispersion (QTd) in each of the 12 leads. Result: This study demonstrates that QT, QTd, QTcd is higher in hemodialysis patients compared with control subjects, and QT and QTd rise postdialysis to levels comparable to those seen acutely following myocardial infarction, when patients are at greatly increased risk of potentially fatal ventricular arrhythmias, Conclusions: QT interval and QT dispersion, markers of risk for arrhythmias and sudden death, are elevated in hemodialysis patients, and rise postdialysis. QT interval and QT dispersion is an easily obtainable, noninvasive, simple, inexpensive, and widely available method of risk stratification in uremic patients receiving chronic dialysis. Additional studies are needed to clarity whether increased postdialysis QT dispersion results in an increased occurrence of arrhythmias.

Composite resin repair requires strong bond strength between the new and old materials. The objective of the current study was to identify the optimal treatments for sufficient bond strengths. Bondings between same kinds of materials and cross bondings using chemical curing composites and light curing composites were tested. Surface treatments included the methods of sand-blasting, acid etching and coating of bonding agent. Seven kinds cases of combinations from three kinds of methods were experimented and compared with a control group of which surfaces were highly polished. Measurements of shear bond strength and observations of surface morphologic changes using a scanning electron microscope were done. Following conclusions were drawn 1. The highest bond strength among composite resins were exhibited by the treatment of the sand-blasting and the coating of bonding agent. 2. Acid etched surfaces showed the lowest bond strength. Bond strengths obtained from experimental groups including acid etching were lower than those obtained from same kinds of experimental groups without acid etching. 3. Simple method of the coating of bonding agent produced the slightly increased bond strength on chemical curing composite and reduced bond strength on light curing composite. 4. Bonding surfaces of chemical curing composite resin showed slightly higher bond strengths than light curing composite resin, however significant differences were not confirmed statistically. 5. More significant irregular surfaces were created by sand-blasting method than acid etching method. 6. A principal component of fillers of both resins was silicon. Acid etching method produced the seperations and degradations of fillers, these were significant on light curing composite resins which containing barium fillers.

강지현,유병연,서희선,심경원 대한비만학회 2002 The Korean journal of obesity Vol.11 No.2

연구배경 : 목둘레는 인슐린저항성과 관련된 여러 질환과 연관되어 있으며 인슐린저항성의 위험이 증가되어 있는 환자들에서 목둘레가 임상적인 선별검사로 유용하게 쓰일 수 있으리라고 제시되어진 바 있다. 따라서 본 연구에서는 목둘레와 비만 관련 지표 및 인슐린저항성의 지표로서의 HOMA score 와의 상관관계를 알아보고, 비만 환자를 예측할 수 있는 최적의 목둘레 분별점을 알아보고자 하였다. 대상 및 방법 : 건양대학병원 종합검진센터에 내원하여 건강검진을 받은 성인 남녀 대상자 364명 (남자 199명, 여자 165명) 중 249명 (남자 136명, 여자 113명) 실험군(test group)로 하여 receiver output curve (ROC) 분석을 통해 체질량지수 25 kg/㎡에 대한 최적의 (optimal) 민감도와 특이도를 가지는 목둘레 분별점을 구하였으며, 나머지 115명 (남자 63명, 여자 52명)을 유효군 (validation group)으로 하여 실험군에서 얻어진 목둘레 분별점을 적용하여 그 유효성을 알아보았다. 또한 묵둘레와 비만 관련 지표 및 인슐린저항성의 지표로서의 HOMA score와의 상관관계를 알아보았다. 결과 : 목둘레는 남녀 대상군 모두에서 허리둘레, 엉덩이 둘레, 엉덩이허리둘레비, 체질량지수, 체지방률, 공복시 혈중 인슐린, HOMA score와 강한 양의 상관관계를 보였으며 실험군에서 비만 환자를 예측할 수 있는 최적의 목둘레의 분별점은 남자에서는 36.6 cm 여자에서는 32.3 cm 였다. 이때의 민감도는 남자 81.92%, 여자 91.5%, 특이도는 남자 77.4%, 여자 69.7%, 정확도는 남자 80.2%, 여자 85%였다. 또한 실험군에서 얻어진 목둘레의 분별점을 유효군에 적용한 결과 남자에서는 민감도 91.9%, 특이도 53.9%, 정확도 76.1%로 나타났으며 여자에서는 민감도 81.25%, 특이도 85%, 정확도 82.69%로 나타났다. 결론 : 본 연구는 측정이 간편한 단순 비만 지표로서의 목둘레와 흔히 사용되는 비만 관련 지표 및 인슐린저항성과의 관련성을 밝혔으며 비만환자를 예측하기 위한 방법으로서 남자 36.6 cm, 여자 32.3 cm라는 목둘레의 분별점을 제시하였다. 향후 보다 일반화할 수 있는 보완 연구가 이루어져야 할 것으로 생각된다. Background : Neck circumference has been reported to be related to the other anthropometric measures of obesity and also associated with the metabolic disorders related to insulin resistance. The measurement of neck circumference could be useful in clinical screening for persons at an enhanced risk for insulin resistance. The aim of this study was to determine whether a single measure of neck circumference might be correlated with other obesity indices and HOMA score and to define neck circumference cutoff levels for obesity. Methods : We examined 364 consecutive persons (199 men and 165 women), who visited konyang university hospital health examination center during August, 2002. To find the optimal, maximal sensitivity and specificity for neck circumference, the receiver output curve (ROC) analysis of cutoff points against BMI (25 kg/㎡) was performed using the test group (136 men and 113 women). We validated the cutoff level using validation group (63 men and 52 women). Other obesity indices and fasting glucose and insulin were measured to find the correlation between neck circumference. Results : Neck circumference was significantly correlated with waist circumference, hip circumference, waist hip ratio, BMI, total body fat percent, fasting insulin and HOMA score. Neck circumference 36.6 cm for men and 32.3 cm for women was the best cutoff levels for determining the subjects with BMI over 25 kg/㎡. In the validation unrelated group, the test characteristics were acceptable with 91.9% sensitivity, 53.9% specificity, and 76.1% accuracy for men, and 81.25% sensitivity, 85% specificity, and 82.69% accuracy for women. Conclusion : Neck circumference as a simple and easy screening method for obesity was strongly correlated with the other conventional obesity indices and HOMA score as a index of insulin resistance and we defined neck circumference cutoff level for obesity according existing BMI cutoff levels.
