  • 본 연구에서는 두 가지 투여그룹을 비교하여 ergogenic aid로서 D-ribose의 효과를 운동영양학적으로 규명하는데 그 목적이 있었고, 이를 위하여 2,000 m 조정운동 전, 운동종료 직후, 그리고 운동 종료 후 회복기 30분의 변화를 연구하였으며, 다음과 같은 결론을 얻었다. 첫째, 투여그룹에 따른 2,000 m 조정운동 수행력의 차이는 없었으며 둘째, 투여그룹에 따른 젖산과 암모니아 수치의 차이도 나타나지 않았다. 셋째, 회복 30분에서 무기인산은 PS에 비해서 RS투여그룹의 수치가 더 낮게 나타났으며, 마지막으로 회복 30분에서 hypoxanthine의 축적은 PS투여그룹에 비해 RS투여그룹의 수치가 더 낮게 나타났다. 따라서, 7-8분 정도의 고강도 운동 시 운동기록의 단축에 D-ribose 구강투여의 효과는 없었지만, 휴식 기 피로회복에 긍정적인 효과를 줄 수 있을 것이라 사료된다.

  • The purpose of this study was to describe the effects of caffeine ingestion on the metabolic responses during submaximal exercise. Ten male of rowing player aged 18-22yrs. participated in the study. No subjects had any remarkable medical history and none were taking medications. According to the administration of dehydrated caffeine(CA) (6mg/kg) or placebo(PA), they were classified into two groups such as caffeine group and placebo group. A randomized, double-blind, crossover protocol was employed using either CA or PA. Subjects underwent a submaximal bicycle ergometer. Blood was drawn intravenously prior to 60 min., at rest, at 30, and 45 min. of exercise, and recovery period. Plasma concentrations of glucose, free fatty acid and lactate were obtained using enzymatic method. Followings were obtained by the tests and analyses; 1) Blood glucose(BG) of 45 minute of exercise was significantly decreased in CA group of 76.3$\pm$14.8 mg/100ml compared with PA group of 94.9$\pm$11.2 mg/100mg(p<0.5). 2) Free fatty acid(FFA) of 30minute of exercise was significantly increased in CA group of 720$\pm$80 $\mu$Eq/1 compared with PA group of 360$\pm$120 $\mu$Eq/1(p<0.5). After exercise, FFA was significantly higher in CA group than those in PA group(p<0.1). 3) Blood lactate(BL) was not significantly different between the two. After exercise, BL was significantly different in 30 minute(p<05).

  • Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowg-rowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom. We excised a schwannoma on the nasal dorsum through direct incision and a schwannoma on the nasal tip through open rhinoplasty. No postoperative complications involving recurrence, hematoma, or infection occurred. The possibility of neurological changes should be considered in cases of an abnormality in the peripheral nervous system. Schwannoma must be kept in mind as a possible cause of neurological changes localized to a specific dermatome, and should always be considered in the differential diagnosis of a mass on the nose.

  • Objectives: It is hard to accumulate research data on adolescents' suicide, because friends and family of the suicide completers might be reluctant to share the experience. To overcome the lack of information on adolescent suicide victims, the authors examined the risk and protective factors for adolescents' suicide from a character in a novel. Methods: Krystal, an adolescent female in the novel The Casual Vacancy by Joanne Rowling, failed to overcome her unfortunate circumstances and committed suicide. The authors analysed Krystal's case based on the guideline for patients with suicidal behaviours to address the complicated situation of her death. Results: Krystal grew up in a poor and dangerous environment. Despite the environmental hardships, she developed ego maturation with affectionate help from Mr Fairbrother, an assistant coach of the Girls' Rowing Team and a parish councillor. The sudden passing away of Mr Fairbrother brought on a crisis of identity for Krystal. In addition, a villainous character raped her and her brother drowned to death, which brought her great sorrow. She felt helpless and committed suicide. Conclusion: In spite of many risk factors for suicide, Krystal was able to keep her life with a few protective factors, a younger brother in the home, and a sense of responsibility for the family. After the loss of her brother, however, she collapsed in a moment. Krystal's suicide might not only be a personal choice but a breakdown of the social protection system for the youth.

  • The purpose of this study was to analyze and determine the relationship between physiological responses including blood flow rate and garment pressure, and the feeling of restrictive tightness associated with the wearing skinny pants as a popular clothing style. Evaluation was based on material type, posture and activity type, and body part location. Five female college students took part in this research. Five kinds of experimental clothes with waist measurements of 66cm were chosen. An analysis of the selected skinny pants demonstrated the degree of the whole looseness was higher in this order: clothing type A>B>D>C, and E with E being knitted cloth. Garment pressure was the highest in the front knee portions and was lowest in the outside thigh region. Garment pressure was highest in this sequence : clothing type C>=D>A>=B>E. In terms of posture and activity types, garment pressure was the highest when research participants were crouching, and was the lowest when standing. The blood flow rate was highest in this order: clothing type E>D>B>A>C. Type C skinny pants impeded blood flow and demonstrated the tightest and most restrictive relationship. Blood flow rate varied depending on the type of movement and was highest in this order: getting up, rowing, kicking, jumping and O-shaped leg posture. The results of subjective pressure evaluation demonstrated that pressure was highest in this order: E>=C>B>A>D. These results suggests the need to improve on the patterns and the material design in the area of the front knees. The degree of the looseness when wearing skinny pants did not always correspond to garment pressure or subjective sensation.

  • The present study was performed to evaluate hemodynamic effects on the pericardial patch graft for stenosis of right ventricle outflow tract in 19 patients of tetralogy of Fallot. The stenosis of right ventricle outflow tract was associated with or without pulmonary annular nar-rowing, pulmonary valvular stenosis, and hypoplastic narrowing of pulmonary artery. Total correction of tetralogy of Fallot was performed under cardiopulmonary bypass with moderate hypothermia and cardioplegic cardiac arrest. Ventricular septal defects were closed with Teflon patch graft. The chamber pressures in the heart were measured before and after a total correction of tetralogy of Fallot. The data of pressure measurement and the results of postoperative observation of pericardial patch were as followings: 1. Systolic and diastolic pressure of right ventricle was decreased after operation from $96.0{\pm}14.7/10.0{\pm}14.4mmHg$ to $61.0{\pm}13.1/8.0{\pm}9.3mmHg$. 2. Systolic and diastolic pressure of pulmonary artery was increased after operation from $18.0{\pm}5.6/10.0{\pm}5.5mmHg$ to $31.0{\pm}10.7/14.0{\pm}4.9mmHg$. 3. Preoperative pressure gradient between right ventricle and pulmonary artery was decreased immediately after operation from 78.0mmHg to 30.0mmHg. 4. It was observed that excellent widening effects of right ventricle outflow tract was resulted from pericardial patch graft. 5. No postoperative bleeding from pericardial patch graft was observed. 6. Aneurysm formation of pericardial patch was not be observed during 1 to 6 years postoperative periods.

  • [Purpose] The composition of protein supplements, the consumption timing immediately before and after resistance exercise training (RET), and the quantity of protein supplementation may be important factors for the im-provement of muscle mass and function. Although these factors should be considered comprehensively for effective improvement of muscular function in protein supplementation, relatively few studies have focused on this area. Therefore, this study was designed to investigate whether a protein blend supplement before and after resistance exercise for 12 weeks would be effective in increasing muscular function. [Methods] In total, 18 participants were randomly assigned to a placebo (PLA) or protein blend supplement (PRO) group. All subjects followed the same training routine 3 times per week for 12 weeks, taking placebo or protein supplements immediately before and after each exercise session. The protein supplement consisted of 40 g of blend protein, including hydrolyzed whey protein. The RET consisted of lower body (barbell squat, dead lift, seated leg extension, and lying leg curl) and upper body (bench press, barbell rowing, preacher bench biceps curl, and dumbbell shoulder press) exercises. A repetition was defined as three sets of 10-12 times with 80% of one repetition maximum (1RM). [Results] Although the PRO group had a lower protein intake in terms of total food intake than the PLA group, the mean changes in muscle circumference, strength, and exercise volume increased, especially at week 12, compared to the PLA group. [Conclusion] These results suggest that the composition and timing of protein intake are more important than the total amount.
