The purpose of this study is to provide the dates for revitalization of taekwondo gym and find the way to effective management of taekwondo gym through the case study of taekwondo gym. To gather information and to achieve these objectives, there was a qualitative case study on in-depth interviews and referring documents from taekwondo master who have over the 300 student in their gym. The collected data was then analyzed by using qualitative study`s analysis in the process of transcription, encoding, categorization and subject formation. The validity and the reliability of this study were verified by triangulation, member checking and peer debriefing and a special effort was made to enhance the morality of the research. The Research results is analyzed by six core categorization: 1. cognition about reality of taekwondo gym, 2. teacher`s education purpose and objective. 3. education programs, 4. gym`s facility, 5. marketing of taekwondo gym, 6. teacher`s quality.

N/A Objectives: The 12-s maximum voluntary ventilation(MVV) provides an estimate of the ventilatory reserves available to meet the physiologic demands of exercise. Earlier studies established a correlation between MVV and forced expiratory volume in one second(FEV1). We hypothesized that the resting maximum inspiratory flow rate(MIFR) may be a determinant of MVV and evaluated MIFR as a predictor varialbe for MVV and also examined some other formulas for calculation of indirect MVV. Methods: Between December 1992 and May 1993, a total of 111 subjects, 85men and 26 women(age 53±5 yr, mean±SD), with expiratory impairment categories of severe(n=22), moderate(n=20), mild(n=17) in patients with chronic obstructive pulmonary disease(COPD) and control (n=52) based on FEV1(percentage of predicted), enrolled the study samples. We measured FEV, MIFR and MVV by body plethysmograph in all subjects and examined the relation between FEV1 and MVV, MIFR and MVV and calculated indirect MVV using the stepwise method of forward multipul linear regression. I present r2 values, coefficients of determination, as measures of linear association for regression relationships. Results: 1) The MIFR correlated with MVV in normal control(p<0.05, r2-0.681) and patients with COPD (p<0.05, r2=0.682) better than FEV. 2) MIFR joined with FEV in multiple linear regression to significantly improve the description of MVV: normal control MVV(L/min) = 20,58FEV1 (L) + 7.11MIFR(L/s) + 49.90(n=52; p<0.05, r2= 0.8735), patients with COPD MVV(L/min) = 36.64FEV1(L) + 4.64MlFR(L/s) - 7.21(n=59; p<0.05, r2=0.7173). Conclusion: MIFR is a significant determinant of MVV in normal control and patients with COPD and also contributes to improuenent in accuracy of indirect estimates of MVV.

N/A Objectives: Mediastinal tumors are not uncommon but almost half of them are asymptomatic because of the potential space of the mediastinum. Recently owing to the routine screening chest roentgenography and frequent chest CT scans the incidence have increased. Mediastinal masses are both benign or malignant. Even benign masses may continue to enlarge and compromise vital organ function or rupture, bleed, and become infected. Mediastinal tumors have their own predilection site. There are different incidences of these masses in adults and children, sexes, and there may be difference in incidence between races. There are only a few reports about these tumors in Korea, and we are interested in the clinical manifestations of mediastinal tumors in Korea, Methods: We retrospectively reviewed medical records of 286 cases of mediastinal tumors which were pathologically confirmed at Keimyung, Kyungpook, and Yeungnam University Hospital in Taegu from 1985 to 1994 but excluded metastatic lesion, tuberculosis, and tumor originated from esophagus, heart, and large vessels. Results: Mediastinal tumors were more frequent in male(60.8%) than female and age distribution was relatively even. Thymoma was most common mediastinal tumor(107 cases, 37.4%). The most common tumor in anterior mediastinum was thymoma (107/212, 50.5%). In posterior mediastinum, neurogenic tumor was the most common(52/67, 77.6%) and teratodermoid tumor was common in middle mediastinum(3/7, 42.9%). The most common symptom was chest discomfort(129 cases, 45.1%) and 67 cases were asymptomatic(23.4%). Benign tumors were more common(175 cases, 61.1%) than malignant tumors. In therapies, complete or partial resections were done in 190 cases(79.8%), chemotherapy or radiotherapy in 71 cases(29.8%), in 24 cases(10.1%) only biopsy was taken without any treatment. Neurogenic tumors have been reported as the most common tumors in western countries and neurogenic and teratodermoid tumor were found to be the most common tumors in the past Korean reports. But thymoma was the most common tumor in this study. Conclusion: Thymoma was the most common mediactinal tumor in this study. And thymoma was the most common tumor in anterior mediastinum neurogenic tumor in posterior rnediastinum and teratodermoid tumor in middle mediastinum
