The purpose of this study is to identify the relations between the ability and the level to perceive leisure in Golf Interest Group Members for Golf Practice Range. Objects for this study were adults who live in young-dong area as of 2008 and participate in Golf Interest Group Members for Golf Practice Range. 236 people were sampled through stratified cluster random sampling after sampling framework was set up. With regard to the survey tool, LDB(Leisure Diagnostic Battery), which was originally produced by Witt and Ellis(1990) and used by Noh Su-yeon (2002), was modified and supplemented to use for this study. The following is the result. The ability and the level to perceive leisure are related.

Recently, the importance of GDI and diesel engine noise reduction is required, so newly designed components very close to noise sources are added in order to maximize the sound absorbing performances. In this study, the high temperature resistant part made with meta-Aramid nonwoven, which was applicable for high temperature applications of about 200 ℃ or more, such as engines and exhaust systems, was developed. And three-dimensional shaped component was successfully fabricated, and it was observed high temperature resistance of 260 ℃, lightweight properties and the noise was decreased by 1.0 dB with 70 g of product.

The recent dormitory construction has been carried out in a build-transfer-release (BTL) method in which a special purpose company (SPC) builds dormitories and rents them for a certain period for financial reasons of universities. J University has several dormitories managed and operated by itself and entrusted to the SPC. This study aims to provide basic data that can be used for future dormitory remodeling or new building plans through the comparative analysis results of two types of facility satisfaction surveys with different dormitory management subjects. As a result of the satisfaction survey on dormitory students, despite the difference in the construction time of the dormitories, the survey confirmed that the evaluation of the dormitory was generally satisfactory and there was no significant difference.

충격파 터널은 다른 지상시험장비에 비해 적은 경비로 쉽게 고엔탈피 환경을 모의할 수 있다는 장점을 가지지만 정상 유동 유지 시간이 수 ms로 짧다는 단점을 가지고 있다. 이에 본 연구진은 정상 유동 유지 시간을 늘리는 방안을 모색하였고 충격파관의 고압관과 저압관 길이 대비에 따른 정상 유동 유지 시간의 변화를 확인하고자 본 연구를 수행하였다. 실험에 앞서 1차원 해석 프로그램으로 충격파관 내의 유동 압력을 계산하여 충격파관 길이 대비에 따른 정상 유동 유지 시간 변화 양상을 확인하였다. 그리고 이를 바탕으로 충격파관 내의 실제 압력 측정 실험을 수행하였다. 본 논문에서는 충격파 터널의 정상 유동 시간 연장에 관한 결과를 비교 및 정리하여 수록하였다. Shock tunnels have the advantage that they can easily simulate high enthalpy condition with less cost compared to other ground test equipment, but they have a disadvantage that the steady flow holding time is short as several milliseconds. In this study, we tried to increase the steady flow holding time and investigated the variation of the steady flow holding time according to the contrast of the driver tube and the driven pipe of the shock tube. Before the experiment, the flow pressure in the shock tube was calculated by the one - dimensional analysis program, and the variation of the steady flow holding time according to the length of the shock tube was confirmed. Based on this, the actual pressure measurement experiment in the shock tube was performed. In this paper, we compare and summarize the results of the extension of the steady flow time of the shock tunnel.

캡차는 사람은 쉽게 판단할 수 있으나 기계는 판단할 수 없는 문제를 이용하여 사람과 기계를 구별하는 기술이다. 널리 사용되고 있는 문자열 기반 캡차는 구현이 간단하나 이미지 기반이나 소리 기반 캡차에 비해 상대적으로 보안성이 약하다. 텍스트 기반 캡차의 보안성을 높이기 위해 다양한 기법이 개발되었으며, 그 중 하나는 복잡한 배경이나 노이즈를 사용하여 기계가 문자를 인식하기 어렵게 만드는 것이다. 이 논문에서는 이미지 프로세싱 기법 중 하나인 콘볼루션 필터링(Convolution Filter)을 이용하여 효과적으로 캡차를 공격하는 방법을 제시하고, 이를 네이버 카페의 캡차에 적용하여 분석해보았다. CAPTCHA is a technique which distinguishes human and machine using what human can judge easily but machine can’t. Though Text-based-CAPTCHA has been widely used and can be implemented easily, it is less security than other CAPTCHAs such as image-based, or audio-based CAPTCHAs. To enhance the security of text-based CAPTCHA, many techniques have been developed. One of them is making CAPTCHA recognized hard using complex background or noise. In this paper, we introduce how to apply convolution filtering effectively to attack CAPTCHA and actually analyze Naver’s CAPTCHA which has been used for joining a cafe with this method.

고혈압의 치료목적은 강압, 합병증의 예방, QoL의 개선이다. 이를 위해 지금까지 약물요법은 물론 운동요법에 관해 많은 연구가 보고되었다. 특히 고혈압은 운동방법, 지도 처방을 각 환자개인의 운동생리학적 특성에 맞추는 것이 필요하다고 사료된다. The intended physical activity, trouble, suppression effect, and mechanism have been fully described with regard to hypertension and exercise therapy. Objects of hypertensive therapy are suppression, prevention against complications, improvement in quality of life. A wide range of researches on excercise therapy including pharmaceutical therapy have been reported to the betterment of hypertension. Above all, compliance is very important to exercise therapy due to the fact that hypertension could be remedied by long-term therapy. It is necessary for each individuals to be adjusted by the ways to exercise, instruction, and prescription for their physiological traits. It is required for the prevention of hypertension that individuals should measure their blood pressure and know their physical fitness on a regular basis.

Purpose: Prompt operative management of patients with peripheral artery embolism remains the treatment of choice for this malady. The clinical status of the limb, rather than the elapsed time from the onset of occlusion, was recently determined to be the best predictor of limb salvage. We investigated the clinical features, therapeutic modalities and treatment results of popliteal artery embolism compared with that of ilio-femoral artery embolism. Methods: A retrospective review was carried out for 21 cases that were treated for lower extremity arterial embolism, from March 2000 to June 2006. The patients were classified into two groups; Group A (ilio-femoral artery embolism, n=11) and Group B (popliteal artery embolism, n=10). We analyzed the interval time from the onset of symptoms to starting treatment (the interval time), the degree of limb ischemia, the therapeutic modalities and the treatment results. Results: The average interval time was 16.2±16.9 hours in the total 21 cases; the average interval time for Group A was 7.7±2.9 hours and that for Group B was 25.5±20.9 hours (P<0.05), and the incidence of severe limb ischemia (class IIb according to the SVS/ISCVS reporting standard) was 72.7% vs 20.0%, respectively (P<0.05). For the therapeutic modalities, surgical thromboembolectomy was performed in all cases of Group A and for 3 cases of Group B. Seven cases of Group B received radiologic intervention (3 cases percutaneous aspiration embolectomy only, and 4 cases of additional thrombolytic therapy). Conclusion: This study shows that the interval time for popliteal artery embolism is longer than that for ilio-femoral artery embolism. In other words, it is suggested that the symptomatic progression of popliteal artery embolism is slower than that of ilio-femoral artery embolism. Therefore, we can have more chances for variable therapeutic options such as surgical thromboembolectomy, percutaneous aspiration embolectomy and/or thrombolytic therapy in patients suffering with popliteal artery embolism.
