This study was to find out calorie intake and body composition changes in accordance with weight loss of wrestlers. The wrestlers were divided three groups : no weight loss groups, 5∼7% weight loss group and over 7% weight loss group. And they were observed three : before weight loss, at measuring weight and before games. The following are the conclusion of this study: 1.The changes of calorie intake 1) Before weight loss, the percentage of the daily intake to the daily energy expenditure was 57.7% for the no weight loss group, 47.2% for the 5%∼7% weight loss group and 53.7% for the over 7% weight loss group. 2) The calorie intake of each group per meal: the no weight loss group intake 1,118kcal before weight loss, 760.9kcal before weight measurement and 1026.8kcal from after weight measurement to before games, and the 5∼7% weight loss group intake 955.4kcal before weight loss, 483.1kcal before weigh measurement and 880.4kcal from after weight measurement to before games, and the over 7% weight intake 959.3kcal before weight loss, 339.4kcal before weight measurement and 872.7kcal from after weight measurement to before games. 3) The ratios of calorie intake(protein : fat : glucose) : the no weight loss group showed 16.7∼35.1% : 20.8∼23.8% : 44.1∼60%, the 5∼7% weight loss group showed 15.5∼26.6% : 22.2∼23.7% : 50.6∼62.3% and the over 7% weight loss group showed 15.0∼30.2% : 19.6∼27,6% : 50.7∼59 4%. 2.The changes in body composition 1) After weight loss, weight and BMI changes in accordance with weight loss among groups showed meaningful differences in all circumstances : weight, before games versus at measuring weight and before weight loss versus before games.(p≤.001) 2) In the changes of total body water, protein, mineral, fat mass and %fat in accordance with weight loss among groups, when we compared those of before games with those of at measuring weight, we found that the over 7% weight loss group showed a meaningful increase over the no weight loss group.(p≤0.5) 3) In the changes within groups, though we found no meaningful difference, total body water, protein and mineral of before games were less than those of before weight loss, and fat mass and %fat of before games were higher than those of before weight loss. According to the results of this study, the wrestlers lost their weights intensively in three days before games by eating less and when lean body mass was restored, the level was lower than before weight loss. Therefore, these results intake the weakness of exercise capacity, long-term weight loss plan is more helpful than short-term weight loss, and for the enhancement of exercise capacity systematic plan and training of the weigh loss should be done.

[논문]지반앵커의 인발저항 특성에 따른 인장 · 압축 복합 시스템 개발

임종철,염호형,권정근 釜山大學校生産技術硏究所 2008 生産技術硏究所論文集 Vol.67 No.-

앵커는 그라우트(grout)의 지지방식에 따라 인장형,압축형, 복합형으로 나누어지며,현재 인장형 앵커의 단점을 보완한 압축형 앵커가 주로 적용되고 있다. 그러나 압축형 앵커는 구속압이 적은 토사지반에 긴장 정착시 그라우트(grout)체가 인발되거나 파괴되는 약점을 가지고 있어 이런 약점을 개선시켜 토사 지반에도 사용 가능한 앵커개발이 필요하다. 본 연구에서는 인장형 및 압축형 앵커의 장점을 동시에 가지며, 특히 토사 및 풍화토에서도 앵커의 소요 인발력을 발휘할 수 있는 복합형 앵커를 개발하였다. 풍화토지반에서의 인발실험 결과 앵커체가 압축변형률과 인장변형률이 발생하는 복합적인 인발저항기구를 보였으며,압축형 앵커에 비해 소성변형이 적게 발생되어 탄성거동에 있어 복합형 앵커가 유리하게 나타났다.

치아 우식증의 발생과 관련된 분야에 대한 연구는 지난 20년간 활발히 진행되어 괄목할만한 발전을 이루었다. 그러나 치아 우식증의 원천적인 예방을 이루기 위해서는 보다 새로운 실험 장비와 기구를 이용한 다각적인 연구가 요구되며, 이러한 흐름에 부응하여 미국의 인디아나 치과대학을 중심으로 초기 법랑질 우식증에 관한 재조명이 집중적으로 이루어지고 있다. 또한 세계적으로 치과계의 지속적인 대민 교육과 홍보 및 불소화 사업 등의 우식 예방에 대한 노력과 구강 보건에 대한 대중의 인식 향상을 통해 치아 우식증이 감소하는 추세에 있으며, 이로 인해 치아 우식증이 기존의 교합면보다 인접면에서 더 많이 발견되는 추세로 변화되고 있다. 치아 우식증의 조기 진단을 목적으로 새로운 진단 장비들이 속속 개발되고 있으며 이미 성능의 우수성이 실험실 연구를 통해 입증된 바 있다. 본 연구의 목적은 초기 인접면 우식증의 진단에 있어 새로 개발된 DIFOTI^(TM) 시스템의 효능을 기존의 방법인 사진 및 교익방사선사진과 비교 평가하고, 임상 적용시의 문제점을 파악하여 차후 DIFOTI^(TM) 시스템 개발에 필요한 개선안을 제시함과 아울러 치아 우식증의 예방 및 불소를 이용한 초기 우식증 재광화 방법에 대한 기초 연구 자료를 마련하고자 하였다. 학동기 연령에 있는 유치 탈락 시기에 근접한 것으로 기대되는 23명의 아동을 대상으로 구강 검진 2회, 구치부 교익 방사선 필름 판독 2회 그리고 전치부 및 구치부 DIFOTI^(TM) 이미지 판독 2회를 실시하고 각 방법에 대한 신뢰도 평가를 시행한 결과 다음과 같은 결론을 얻었다. 1. 구강 검진시 검사자간 신뢰도는 교합면에서 평균 0.8470으로 가장 높았으며, 근심면 평균 0.6430 원심면 평균 0.5727, 설면 평균 0.2807 그리고 협면 평균 0.2339 순으로 나타났다. 구치부에 국한시킨 경우 교합면에서는 평균 0.8577이었으며, 원심면 평균 0.8211, 설면 평균 0.7728, 협면 평균 0.7152, 근심면 평균 0.6782 순으로 나타났다. 2. 구치부 교익 방사선 사진 판독 결과에 대한 검사자간 신뢰도는 교합면 평균 0.8346, 근심면 평균 0.8675, 원심면 평균 0.8482 순으로 나타났다. 3. DIFOTI^(TM) 이미지 판독 결과에 대한 검사자간 신뢰도는 교합면 평균 0.8437, 협면 평균 8379, 근심면 평균 0.8223, 설면 평균 0.7766, 원심면 평균 0.6781 순으로 나타났다. 4. 치아 우식증 진단율을 비교한 결과 교합면, 협면, 설면에서는 DIFOTI^(TM) 이미지 판독이 가장 우수한 것으로 나타났으며(p<0.05), 근심면과 원심면에서는 방사선 판독이 가장 우수한 것으로 나타났다(p<0.05). Over the past 20 years, great strides have been made in research regarding the mechanisms involved in the progression of carious lesions, but new equipment and research tools need to be developed to continue these advancements in caries research. Various methods have been applied to reduce the incidence of carious lesions, which have led to a significant decrease in the number of occlusal caries, but a concurrent increase in the proportion of proximal carious lesions. New diagnostic equipment has been developed to detect early stage carious lesions, and these have demonstrated excellent laboratory results and show promise in clinical applications. The research presented here examines the efficacy of the newly developed DIFOTI^(TM) system in detecting proximal carious lesions compared to traditional intraoral exam and bitewing radiography, possible problems or deficiencies of using the system in clinic, possible improvements that can be made to the system, and the efficacy of detecting early, reversible carious lesions that can be remineralized by preventative fluoride applications. The subject pool consisted of 23 grammer school age patients just prior to entering the mixed dentition phase. Each patient was given a thorough oral examination, radiographic examination consisting of bitewing radiographs of the posterior teeth, and DIFOTIR examination of the anterior and posterior teeth. Each examination was carried out two times by two examiners, and the data were statistically analyzed. The results are as follows: 1. The mean alpha value of reliability test of the visual oral examination was as follows: occlusal surface was 0.8470, mesial surface was 0.6430, distal surface was 0.5727, lingual surface was 0.2807 and distal surface was 0.2339. When the examination was limited to posterior teeth, the mean alpha value was as follows: occlusal surface was 0.8577, distal surface was 0.8211, lingual surface was 0.7728, buccal surface was 0.7152 and mesial surface was 0.6782. 2. The alpha value of reliability test of the radiographic analysis of carious lesions of the occlusal, mesial, and distal surfaces was 0.8500. 3. The alpha value of reliability test of the DIFOTI^(TM) diagnostic analysis of carious lesions of the occlusal, buccal, lingual, mesial, and distal surfaces was determined to be 0.7917. 4. The DIFOTI^(TM) diagnostic system was found to be the most accurate means of detecting occlusal, buccal, and lingual surface carious lesions (p<0.05), while mesial and distal proximal carious lesions were most accurately assessed using bitewing radiography (p<0.05).

Subcutaneous emphysema, pneumomediastinum and pneumothorax are used to mean air that appears where it is not normally seen and they also are life-threatening pathologic condition which has to be treaed immediately. Such complications are rare during the operation especially arthroscopic surgery. Recently, we experienced such complications during arthroscopic shoulder surgery in patients without any pulmonary lesions in both preoperative chest X-ray and CT scan taken postoperatively. Such extra-alveolar air can be arised from both chest and extra-alveolar tissue which spread secondarily to the chest, producing mediastinal emphysema. Although the precise mechanism of the subcutaneous emphysema, pneumomediastinum and bilateral penumothorax is not known in this case, transient change of pressure in the joint space relative to atmospheric pressure under the arthroscopy rather than sudden increase in the airway pressure which leads to alveolar rupture during the mechanical ventilation is the suspected one.

Pulmonary arterial sling, a rare developmental vascular anomaly forms a sling around the distal trachea and the proximal right main bronchus, where it sometimes makes tracheo-bronchial stenosis. Tracheo-bronchial stenosis from pulmonary arterial sling may produce non-specific symptoms of stridor, noisy breathing, dyspnea, recurrent upper respiratory tract infection, chronic cough, and dysphagia. The diagnosis of this anomaly begins with a high index of suspicion because of the lack of pathognomonic finding on usual evaluation. In this case, initial difficult intubation makes us evaluate further. Other cases reported the diagnosis is established by imaging studies, usually MRI and angiography. But, when our case was evaluated, we used cervico-thoracic enhanced computered tomography and tracheal fluoroscopy. Up to now, tracheobronchial stenosis from vascular anomaly is a rare and challenging disorder with a poor prognosis. However, early exact diagnosis would make us perform the accurate surgical treatment and reduce the mortality and morbidity.

These experiments were performed to investigate the effects of the KAGAM-DANGKWI-BOHYUL TANG(KDBT) extract, clinically used in gynecology, on the hemostatis and on the contractile force of the isolated uterine muscle. The bleeding time and the plasma prothrombin time test were employed as the means to estimate the hemostatic effect of KDBT extract, and the contractile effect of the extract was measured. The experimental results were summarized as followings; 1. In mice treated with KDBT extract the plasm prothrombin time and the bleeding time were remarkably shortened compared with the control group. 2. The contractile effect of KDBT extract on the isolated uterine muscle was not blocked by atropine and cyproheptadine. 3. The contractile effect of KDBT extract on the isolated uterine muscle was inhibited by the pretreatment with verapamil. From these experimental results, it is concluded that the hemostatic effect of KDBT extract might be attributed to the stimulation of prothrombin formation and the direct contraction of the uterine muscle through the increasing uptake of calcium ions into the muscle.
