As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

이 연구는 트레드밀 운동과 키네시오 테이핑의 효과에 따른 폐활량의 변화를 알아보기 위해 26명의 비흡연자가 참가하였으며 키네시오 테이핑을 적용하지 않은 그룹과 키네시오 테이핑을 적용한 두 그룹으로 무작위로 배정하고 각 군들을 주 3회 6주간의 트레드밀 훈련을 실시하였다. 실험 전과 후, 스파이로미터를 사용하여 키네시오 테이핑의 적용 따른 폐활량 변화 효과를 측정하였다. 이 연구의 결과를 종합해보면 키네시오 테이핑을 적용 그룹에서 적용하지 않은 그룹에 비해 FVC, FEV1에서 유의한 증가를 보였다. 이러한 결과는 건강한 성인에서 키네시오 테이핑을 적용한 경우 키네시오 테이핑을 적용하지 않고 트레드밀 운동을 한 경우보다 폐활량의 향상에 효과적이라고 생각되어진다. The purpose of this study was to investigate the variation of vital capacity(VC) according to the effects of kinesio taping with treadmill exercise. Twenty-six non-smokers were participated in this research and these subjects were randomly assigned into two groups. To measure the VC variation effects of kinesio taping, spirometer was used. The collected data were analyzed statistically by using a paired Mauchly test and repeated measure ANOVA. The results of this study were as follows; A group: treadmill with kinesio taping B group: treadmill without kinesio taping. Between A and B, there were significant differences. In the case of A group, there was 11.66% increase of VC, during 3 weeks experiment(p<.01). In the case of B group, there were significant differences, 3.35% increase of VC, during 3 weeks taping intervention(p<.01). After 6 weeks experiment, the improvement of VC shown a significant difference with intergroup (p<.05). From this result, it was revealed that treadmill exercise with kinesio taping was effective to improve VC to healthy adult than treadmill exercise without kinesio taping.

Background : Studies on cytomegalovirus (CMV) diseases in Korean hematopoietic stem cell transplant (HSCT) recipients are lacking and do not reflect the recent trends of advances and changes. Therefore, we tried to analyze the clinical features of CMV diseases in HSCT recipients over the past 10 years at a tertiary university hospital in Korea. Methods : Retrospective review of medical records was done for all adult HSCT patients who received transplant at the Catholic HSCT Center from January 1998 to January 2008. Results : Forty-four cases (2.2%) of CMV diseases were identified. CMV pneumonia was diagnosed in 17 patients, retinitis in 16 patients, enterocolitis in 7 patients, esophagitis 1 patient, gastritis in 1 patient, duodenitis in 1 patient, and hepatitis in 1 patient. The median onset of symptom was 90 days after transplantation. Late CMV diseases accounted for 47.7%. CMV related death varied from 0 to 58.8% according to the involved organ. CMV retinitis was diagnosed relatively later in the course of transplantation mostly in patients who had chronic graft versus host disease (GVHD). On the contrary, CMV enterocolitis mainly occurred in patients who suffered from acute GVHD. The overall concurrent CMV reactivation was documented to be 63.6%: the concurrent CMV reactivation was observed only in 37.5% of patients with retinitis. Conclusions : We observed some differences in the pattern of CMV disease manifestation according to the involved organ and reconfirmed the fact that CMV pneumonia is the most common and fatal disease in HSCT recipients. Additionally, CMV retinitis was not uncommon in HSCT recipients. Since specific marker does not exist in predicting retinitis, regular ocular examination should be done thoroughly, especially in patients with chronic GVHD.

The Internet of Things, the core of the Fourth Industrial Revolution, is growing by applying various technologies to various fields. Among them, smart home systems that apply IoT technology to home environments are actively being researched, and the home hub market, which is a communication medium for smart homes, is also developing at the same time. However, the security damage from cyber attacks, which are vulnerabilities in IoT technology, is also increasing in proportion to these developments. In this paper, mirror is implemented as an IoT service hub. It can be used in any space where a mirror is installed, and gesture recognition allows control of existing infrared-based devices as well as certain compatible devices. In addition, the system to solve security problems was implemented by applying AES algorithms between all data communications.

Unlike conventional wearable healthcare systems, the proposed system provides real-time telemedicine and diagnosis and the direct connection with doctors is possible through it. And almost all functions of the application in it are operated with voice commands to lower user access barriers. Because it deals with personal information including medical information, encryption algorithms have been applied between all data movements. Finally, the healthcare system proposed in this paper is expected to increase convenience in health care and reduce the medical gap.

높은 받음각에서 양항 특성의 향상을 위한 공력 보조 PANEL에 관한 연구

신동진,이봉준 한국항공운항학회 1994 한국항공운항학회지 Vol.2 No.-

항공기에 사용되는 2차 조종면은 플랩, 탭, 스포일러 등 여러 종류가 있으며 이중 spoiler는 공력제어 기능을 가지고 항공기의 조정성에 영향을 미치는 조종면으로 속도 감속이나 옆놀이 조종용으로 사용된다. 본 연구에서는 비행제어용 spoiler 기능과 고양항력을 얻을 수 있는 새로운 장치인 고양항력 panel에 대한 공력특성 및 비행제어 특성에 대하여 연구하였다. 이러한 고양항력 panel은 재래식인 spoiler가 양력을 감소시키고 항력만 증가시키는 장치인데 반하여 양력과 항력을 동시에 증가 시킬 수 있는 새로운 장치로서 날개의 앞전 뒷면에 스팬방향으로 설치하여 슬롯효과를 발생시킴으로써 최대 양력 받음각에서 앞전에서의 박리를 막아 비행기의 착륙시 양력의 급작스러운 감소로 인한 불안정성을 감소시키게 된다. 본 논문에서는 직사각형 날개 및 FA-200모형의 날개위에 고양항력 panel을 설치하여 풍동실험 및 수치계산을 한 결과를 기술하였다. 실험결과 직사각형 날개의 경우 고양항력 panel의 위치는 날개의 앞전에 설치할 경우 고받음각에서 실속지연의 효과와 함께 후방실속의 특성을 향상 시킬 수 있으며, 항력의 증가로 인한 스포일러 효과를 얻을 수 있다. 양항비특성은 고양항력 panel을 날개의 앞전에 설치하고, 그 폭이 시위의 1/5이고, 붙임각 θ가 10°, 높이가 시위의 3/20일 때 받음각 18° 이후에서 우수한 특성을 나타내었다. FA-200 모형의 경우 옆놀이 모멘트계수는 받음각이 작을 때 고양항력 panel의 슬롯간격과 붙임각이 작을수록 커지나 받음각이 커지면 붙임각이 커짐에 따라 증가함을 알 수 있다. 또한 키놀이 모멘트계수는 크게 변화하지 않으나 항력 특성은 고양항력 panel의 붙임각이 증가함에 따라 증가하였다. 고양항력 panel의 붙임각이 큰 범위에서(θ=10°) 공기력의 증가는 고양항력 panel의 시위가 날개시위의 30%이고 슬롯의 폭이 날개시위의 10%일 때 증가하는 결과를 얻을 수 있다.

C/C복합체와 Graphite의 기계적 물성및 내산화성 증진

신동우,김법진 국립경상대학교 공과대학부설 첨단소재연구소 1995 尖端素材 Vol.5 No.-

본 연구에서는 탄소/탄소 복합체의 내산화성을 증진시키기 위하여 CVD법에 의한 SiC코팅과 PCS함침법을 응용하여 실험을 행하였다. 전자현미경으로 시편의 미세구조를 관찰한 결과 CVD법에 의해서는 표면에 SiC가 고르게 증착되었으며, 함침법에 의해서는 각 탄소 섬유의 표면에 PCS가 wetting된 후, SiC로의 전이가 잘 일어났음을 확인할 수 있었고, 이로 인하여 각 섬유들의 결합력을 증대시키고 기계적물성에 증진을 가져왔음을 확인하였다. PCS 함침된 탄소/ 탄소 복합체 시편은 함침되지 않은 시편에 비해 밀도는 25%, 곡강도 값은 3.5배, 내산화성은 2.8배가 증가하는 현격한 기계적 물성이 증가함을 보였다. 이러한 증가는 CVD법에 의해 코팅된 탄소/탄소 복합체 시편 보다도 우수한 기계적 성질을 보여주었다. Applicability of SiC coating through CVD process and PCS.(polycarbosilane) impregnation for the oxidation resistance and mechanical properties of C/C composite and graphite was studied. The SiC layer coated by CVD was deposited uniformly on the C/C composite, whereas the SiC converted from PCS impregnation wetted around individual carbon fiber. The PCS-impregnated C/C composite exhibited a significant increase of bending strength in comparison with as-received C/C composite. This increase in the mechanical property could be attributed to the high bonding strength between fibers due to an impregnated SiC phase. The PCS-impregnated C/C showed 25% improvement in density, 3.5 times higher MOR and 2.8 times higher oxidation resistance compared to the as-received C/C. The increments due to PCS impregantion were more effective than CVD process.
