급성전골수구성백혈병에서 arsenic trioxide를 중심으로 한 관해유도

민창기 ( Chang Ki Min ) 대한내과학회 2008 대한내과학회지 Vol.74 No.6

In acute promyelocytic leukemia (APL), all-trans retinoic acid (ATRA) triggers cell differentiation, while arsenic trioxide (ATO) generates partial differentiation and apoptosis. Standard initial treatment for patients with APL consists of chemotherapy, usually an anthracycline, and ATRA. It now appears that it is important to administer consolidation chemotherapy and to include ATRA in both the induction and maintenance phases of treatment. ATO, which is rarely associated with cardiac toxicity, has been shown to be the best reported salvage therapy for patients with APL who relapse following an initial remission. Moreover, ATO treatment can yield a high quality clinical/molecular remission and disease-free survival in relapsed as well as newly diagnosed APL patients. ATO may be effective as first-line treatment for APL, even though the results of ATO combination therapy with chemotherapy/ATRA requires further study.(Korean J Med 74:593-595, 2008)

태권도 선수의 단기간 체중감량이 스트레스호르몬과 피로물질에 미치는 영향

민창기 ( Chang Ki Min ),김동균 ( Dong Kyun Kim ) 대한무도학회 2010 대한무도학회지 Vol.12 No.1

본 연구의 목적은 태권도 선수의 서로 다른 체중감량방법을 비교·분석하여 계체 후 스트레스와 피로물질에 어떤 영향을 미치는지 규명하는데 있으며, 효과적인 체중감량방법을 도출하여 경기력 향상에 도움을 주는데 있다. 고등학교 태권도 선수를 21명 대상으로 정기적인 운동 후 30분 동안 A Group(Running), B Group(Running+Sauna), C Group(Sauna)으로 3일간 자기체중의 6%를 체중감량을 하였다. 채혈은 계체 전 과 계체 후 30분이 지난 시점에서 전완주정맥에서 채혈하였으며 카테콜라민의 경우 HPLC 방법, 젖산의 경우 비색법 방법을 실시하였으며 체중감량방법간의 스트레스 호르몬과 젖산의 변화량을 측정한 결과 다음과 같은 결론을 얻을 수 있었다. 런닝과 사우나를 병행한 그룹에서 런닝과 사우나만 실시한 그룹보다 카테콜라민에 긍정적인 영향을 미친 것을 알 수 있었다. 하지만 피로물질인 젖산은 복합처치가 신체의 대사기능이 떨어짐으로써 심폐기능이 저하로 인한 피로도와 경기력의 저하를 가져올 가능성이 있다고 사료된다. 그러므로 단기간 체중감량 보다는 장기간 체중감량을 체계적으로 실시한다면 경기력 향상에 도움을 줄 것으로 사료된다. For the purpose of this study, an experiment was conducted with 21 high school Taekwondo athletes. They were put to a weight-loss training program after their routines separated in three different groups, namely Group A (Running), Group B (Running + Sauna), and Group C (Sauna), for 30 minutes to reduce 6% of their body weight. The blood samples will be taken 30 minutes before and after the body weight measurements from the vein at the fore arms. And HPLC method was applied for Catecholamine and colorimetry was applied for lactic acid. After measuring the amount differences between the weight-loss methods in terms of stress hormones and lactic acids, the following discoveries have been made. In the end, the group which was engaged in both the running and sauna treatment showed a positive effect on Catecholamine compared to the groups engaged in running and sauna only, respectively. However, as for the lactic acid, which is a fatigue substance, it may leave a negative impact on the athletes` performance as the metabolic function gets hindered due to the combined treatment, causing fatigue and impediment in cardio-function. Therefore, it is recommended to avoid losing weight in a short-term period. A systematic weight loss program over a long term will positively enhance the performance of the athlete, instead.

Mainly to analyse the biomechanical variables for the successful attack factors in Kumdo bouts. In this context, 34 games with 36 players, that were filmed by S-VHS video camera. The bouts included 34 games of 27 preliminary matches for National Kumdo Championship Tournament of President Cup held in November 2009 and final 7 games of the round of 8 groups. For game content analysis, attack frequency, success rate, failure rate, gain, and gain time by section were considered. Based on this condition, I analyzed the pace, speed, angle between bamboo sword and ground, angle speed of bamboo sword"s first part, and its movement, attack distance and stroke time that give impact on the outcome of the match when attacking head and wrist were analyzed. And for the evaluation of related factors in attacking movement, the regression analysis of logistics about the biomechanical variables were employed. Through this analysis of biomechanical variables and game contents, the following outcomes were drawn. Among the biomechanical variables that showed the significance in statistics were the pace, angle speed of bamboo sword, and the attack range. The pace for correct posture and movement was 48.7±25.6cm in successful attack of head and 65.2±23.3cm in failure. Among the biomechanical variables that had an effect on attacking movement, the pace and attacking distance were related in attacking head. The ratio of the pace compared to the height was 26.4±14.1% in that of wrist. In aspects of biomechanical factors, pace and attack distance showed the relations with the outcome of performances in attacking head. For effective strikes in biomechanic process, even no significant variables in statistics are to be considered for efficient technique combined with physical and co-responsiveness. Therefore it is recommended that strikes, maintaining the spiritual and physical drive in successful performances will be integrated ineffective drills.

The purpose of this study is to form a night-view at a university to satisfy users through case studies of four representative university campuses with analyzing the lighting conditions and facility satisfaction. The result of this study is following. From the present lighting status, there are 664(l9types) lightings at Kyunghee University, 350(17types) at Sungkyunkwan University and 437(l9types) at Ajou University. Main materials of the lightings are metal, iron and stainless. Moreover, most illuminants are white-colored metal-halide lamp. There is no specially designed lighting facility because ready-made goods were used. Furthermore, the locations of lightings are not suitable so some are useless. Most main spatial illuminations are not satisfying outdoor standard, so it can be concluded that the designs of present campuses are not carrying on with-out plans. From the result, present campus lighting does not satisfy the desire of users in aesthetic and functional point of view but consider the luminosity. However, even though the luminosity does not standardize the law. It is because the design does not reflect a suitable standard with desire of users and it does not have a long term plan. Moreover, the campus design has no study about development plan even though it has enough green area which has a potential possibility to overcome the lack of green areas in a city. Therefore, it is needed to design a comprehensive campus plan which satisfies the desire of students and residents with considering promotion of excitement and harmony through adjusting luminosity of the lighting facilities and supplying various lighting resources.
