Where no records are available at a site, a preliminary estimate may be made from relations between floods and catchment characteristics. Anumber of these characteristics were chosen for testing and were measured for those catchments where mean annual flood estimates were available. Although the improvement using extended data in regression of flood estimates on catchment characteristics was small, this may be due to the limitations of the regression model. When an individual short term record is to be extended, more detailed attention can be given; an example is presented of the technique which should be adopted in practice, particularly when a short term record covers a period which is known to be biassed. A method of extending the peaks over a threshold series is presented with a numerical example. The extension of records directly from rainfall by means of a conceptual model is discussed, although the application of such methods is likely to be limited by lack of recording raingauge information. Methods of combining information from various sources are discussed in terms of information from catchment characteristics supplemented by records, but are generally applicable to different sources of information. The application of this technique to estimating the probable maximum flood requires more conservative assumptions about the antecedent condition, storm profile and unit hydrograph. It is suggested that the profile and catchment wetness index at the start of the design duration should be based on the assumption that the estimated maximum rainfall occurs in all durations centered on the storm peak.

김대현,최승권,김운기 용인대학교 2009 특수체육연구 Vol.6 No.-

본 연구는 휠체어농구선수와 장애가 없이 휠체어농구를 하는 선수 간 심리기술 및 자기관리의 수준과 심리기술이 자기관리에 미치는 영향력을 알아보고자 하는데 목적이 있다. 본 연구는 2008년 현재 대한장애인농구협회에 등록된 모든 선수를 대상으로 실시하였으며, 응답이 부실한 설문지를 제외한 총 106명의 설문지를 대상으로 자료를 분석하였다. 설문에 응답한 106명 중 휠체어농구선수 집단은 59명, 장애가 없는 휠체어농구선수 집단은 47명이었다. 본 연구의 조사도구는 유진(1996)의 운동선수 심리기술 검사지와 허정훈(2003)의 운동선수 자기관리 검사지를 사용하였다. 조사도구에 대한 타당성 검증은 탐색적 요인분석을 실시하였고 신뢰도 검증은 Cronbach's α를 실시하였다. 조사한 자료의 분석은 two-way ANOVA, Multiple Regression analysis를 실시하였으며, 유의수준은 α<.05로 설정하였다. 자료 분석 결과, 첫째, 장애유무와 포지션에 따른 심리기술에서는, 휠체어농구선수집단이 집중력과 불안조절에서 장애가 없는 휠체어농구선수 집단보다 높은 수준을 나타냈다. 둘째, 장애유무와 경력에 따른 심리기술 중 목표설정과 심상에서 경력이 짧은 집단은 장애가 없는 휠체어농구선수집단이 높은 수준을 나타냈고, 그와 반대로 경력이 오래된 집단에서는 휠체어농구선수집단이 높은 수준을 나타냈다. 또한, 경력 4-6년 집단이 목표설정과 심상에서 제일 높은 수준을 나타냈다. 셋째, 선수들의 심리기술이 자기관리에 미치는 영향에서는 몸관리에서 목표설정과 팀조화가 영향을 미쳤고, 대인관리에서는 팀조화, 심상, 의지력이 영향을 미쳤으며, 훈련관리에서는 의지력, 심상, 목표설정, 팀조화가 영향을 미치는 것으로 나타났다. 이에 따라, 경기력 향상을 위해서는 휠체어농구 선수들에게 체력훈련과 기술훈련 외에 심리훈련을 병행 실시해야 할 것이다. The purpose of this study was to examine the level and relative influence of the psychological skills and self-management of wheelchair basketball athletes and able-bodied wheelchair basketball athletes. The subjects in this study were carried with every athlete who registered with the Korea Wheelchair Basketball Federation. After a survey was conducted, the answer sheets from 106 participants were analyzed except for incomplete ones. Out of the 106 respondents, 59 persons were WA group, and 47 persons were AWA group. The instruments used in this study were Yu Jin's Athlete Psychological Skills Inventory and Heo Jeong-hun (2002)'s Athlete Self-Management Inventory. To verify the validity of the instruments, an exploratory factor analysis was carried out, and Cronbach alpha coefficient was utilized to test their reliability. For data analysis, two-way ANOVA, one-way ANOVA and multiple regression analysis were employed, and the level of significance was set at α<.05. As a result of data analysis, First, as for the relationship of the presence or absence of disabilities and position to psychological skills, the WA group was ahead of the AWA group in concentration and anxiety-control. Second, concerning the relationship of disabilities and career to psychological skills, the less-experienced athletes of the AWA group excelled their counterparts of the WA group at goal-setting and imagery, which were two of psychological skills. In the event of the experienced athletes, however, the WA group surpassed the AWA group in those regards. The athletes who had served as athletes for four to six years were most excellent in goal-setting and imagery. Third, the grade of skills made no difference to their level of psychological skills and self-management. Fourth, as to the impact of psychological skills on self-management, their healthcare was under the influence of goal-setting and teamwork; and teamwork, imagery and will-power had an impact on interpersonal skills. Training-management was affected by will-power, imagery, goal-setting and teamwork. Consequently, in aim to advance the athletic performance, it should co-apply psychological practice for the wheelchair basketball players in accordance with physical training and technical skill.

Background: The aim of this study was to determine whether the conventional subcostal approach is suitable for emergency pericardiocentesis in patients with cardiac tamponade or impending cardiac tamponade. Methods: This study was a prospective, observational study conducted at the emergency department of a tertiary hospital, Patients who had symptomatic pericardial effusion and who needed emergency pericardiocentesis in the emergency department were included in this study. We measured the epicardium-to-pericardium distance at the subcostal, parasternal, and apical area with two-dimensional echocardiography to determine the appropriate puncture site for pericardiocentesis. An epicardium-to-pericardium distance of more than 1.0 cm was considered as the primary safety factor in determining the Puncture site for pericardiocentesis. The skin-to-pericardium distance was considered as secondary safety factor. Results: Ninety-five consecutive patients(55 males and 40 females; total mean age: 53 year old) with cardiac tamponade or impending cardiac tamponade were enrolled in this study. The puncture site for pericardiocentesis, as determined by echocardiography, was the subcostal area in 43 patients(45%), the apical area in 40 patients(42%), the left parasternal area In 11 patients(12%), and the right parastemal area in one patient(1%). Pericardiocentesis failed in 2 patients(2%) with the subcostal approach and in one patient(1%) with the apical approach. The average epicardium-to-pericardium distance was 31 ±21 mm in patients with the subcostal approach and 21±8 mm in patients with other approaches. There were no differences in the amount of pericardial fluid and in the intraperical pressure among patient groups according to puncture site. There were two procedure related complications: a puncture of the right ventricle with the subcostal approach and a ventricular tachycardia with the apical approach.

Graves 병과 혈청 면역글로불린-E의 연관성

김현영,박기룡,김성훈,김지연,송수근,최영식,박요한 대한내분비학회 2002 Endocrinology and metabolism Vol.17 No.5

연구배경: Graves 병은 미만성 갑상선종, 갑상선기능한진, 안구침법 등을 특징으로 하는 자가면역성 질환으로, 갑상선자극호르몬 수용체에 대한 자가항체(TRAb)가 갑상선을 자극하여 발생된다. TRAb는 Graves병 환자의 약 85%이상에서 검출되며 활성화된 TRAb는 대부분 IgE로 알려져 있다. 그러나 최근 Graves병 환자의 갑상선조직과 안구조직에 IgE의 침착과 꽃가루 등에 의한 알레르기성 비염으로 인해 Graves병이 발생하거나 재발된 견우가 보고되어 Graves병의 병인에 IgE의 연관성이 제기 되고 있으나, 국내에서는 이에 대한 연구가 드물다. 본 연구에서는 Graves병에서의 혈청 IgE농도와 Graves병의 병기와의 관계 및 TRAb와 IgE 농도와의 연관성을 살펴보고자 하였다. 대상 및 방법 : 2000년 4월 1일부터 7월 1일까지 고신의료원 내분비내과를 방문한 환자 중 Graves병 46예, 만성갑상선염 6예 및 고신의료원 건강증진센터를 방문한 환자 중 갑상선질환의 병력이나 가족력 및 알레르기성 비염의 병력이 없는 35예의 정상대조군을 대상으로 연구를 시행하였다. TRAb는 갑상선자극호르몬 결합 억제 면역글로불린(TBII)으로 측정하였으며, IgE는 효소면역분석법으로 측정하였다. 결과: IgG인 TBII는 Graves병에서 만성갑상선염과 대조군에 비해 높았으며, IgE 평균농도는 Graves병에서 598.1±1112.9U/mL로 만성갑상선염 환자의 98350±79.7U/mL, 대조군 161.72±194.4U/mL에 비해 높았다(p<0.05). Graves병에서 알레르기성 비염의 발병율은 10.9%(5/46)였으며, Graves 병에서의 혈청 IgE 농도는 알레르기성 비염의 병력이 있는 경우 903.1±1152.2U/mL로 없는 경우 560.8±1117.0U/mL보다 높은 경향을 보였다. Graves병의 병기에 따른 TBII와 IgE 농도의 변화를 항갑상선제로 치료하지 않은 군(비치료군)과 치료한 군(치료군) 및 재발군으로 나누어 비교하였을 때, TBII는 치료군(7.4±18.6%)에 비해 비치료군(49.9±23.9%)과 재발군(21.1±3.1%)에서 높았으며(p<0.05), 혈청 IgE치도 치료군(233.8±432.7U/mL)에 비해 비치료군(758.6±1250.0U/mL)과 재발군(1198.5±1952.1U/mL)에서 높은 경향을 보였다. 항갑상선제로 치료한 치료기간에 따른 TBII와 IgE 농도 변화에서, TBII는 비치료군(49.9±23.9%)과 1년 미만 치료군(24.8±3.8%)에서 1년 이상 치료군(2.22±1.97%)에 비해 높았으며(p<0.05), 혈청 IgE 농도는 비치료군(758.6±1250.2U/mL)에서 1년 미만 치료한 군(158.3±91.5U/mL)과 1년 이상 치료군(252.7±483.4U/mL)에 비해 높았으나 유의하지는 않았다. 결론: Graves 병에서 IgE 농도는 증가되어 있었으며, Graves 병의 각각 다른 병기에서의 혈청 IgE 농도의 변화는 Graves qudd의 경과에 영향을 미치는 IgG인 TBII치의 변화와 유사한 경향을 보였다. 그러나 혈청 IgE와 Graves 병과의 연관성을 알아보기 위해서 IgE와 더불어 CD23항원 등의 다른 검사도 병행하는 전향적 연구가 필요할 것으로 생각된다. Background: It is widely believed that Graves' disease is and autoimmune disorder characterized by the presence of the circulation TSH receptor antibody (TRAb). The majority of the activity of TRAb is of the immunoglobulin G(IgG) class. However, other immunoglobulin such as immunoglobulin E(IgE), may play a rloe in the activity. IgE accumulation has been reported to occur in the thyroid gland and ocular muscles of subjects with Graves' disease. Furthermore, it has been noted that recurrence of Graves' disease can be induced by and allergy to pollen. Because an allergy to pollen is commonly associated with IgE, IgE might play a role in the induction of Graves' disease. Therefore, investigated whether IgE was elevated in Graves' disease, and evaluated the potential relationship between the levels of TRAb and IgE Graves' disease. Methods: Forty-six patients with Graves' disease, and 6 with chronic thyroiditis, diagnosed at the Kosin Medical Center between April, 2000 and July, 2000 were included in this study. Thirty-five persons without thyroid disease or a history of allergic rhinitis were used as normal controls. The level or TRAb was measured using thyrotropin binding inhibitory immunoglobulin (TBII). Serum total IgE was measured using as enzymeimmunoassay method. Test for thyroid function, TBII and total IgE were performed in all cases, and the results statistically analyzed. Results: TBII, as IgG, and the serum IgE level were higher in the patients with Graves' disease, and the levels of the latter were 598.1±1112.9U/mL, 98.5±79.7U/mL and controls 161.7±194.4U/mL in the Graves' patients, those with thyroiditis and the controls, respectively (p<0.05). The prevalence of allergic rhinitis in Graves' disease was 10.9%. The serum IgE level in Graves' disease with, and without, allergic rhinitis were 903.1±1152.2U/mL and 560.8±1117.0U/mL, respectively, although there was no significancant difference between the two groups. According to the clinical stage, the serum TBII level was higher in the untreated Graves', and relapsed patients 49.9±23.9% and 21.1±3.1%, respectively, than in the treated group, 7.4±18.6% (p<0.05). The serum IgE level was higher in the untreated Graves' and relapsed patients 758.6±1250.2U/mL and 1198.5±1952.1U/mL, respectively, than in the treated group 233.8±432.7U/mL, although this was not significant. According to the duration of treatment, the serum TBII levels were higher in the untreated Graves' patients, and those treated for less than 1 year, than in those treated for more than 1 year, with values of 49.9±23.9, 24.8±3.8 and 2.22±1.97%, respectively (p<.05). The serum IgE level was higher in the untreated Graves' disease (758.6±1250.2U/mL) than in the groups treated for less than 12 months (158.3±91.5U/mL) and more than 12 months (252.7±483.4U/mL), but the differences were not significant. Conclusions: The concentration of IgE was high in Graves' patients, and although not statistically significant, the serum igE level in Graves' patients with allergic rhinitis was higher than those without. With regard to the clinical stage of Grave's disease, the change in the IgE level tended to follow that of the TBII. Further study will be required to define the possible role of IgE in the pathogenesis in Graves' disease (J Kor Soc Endocrinol 17:640∼648, 2002).
