Possibility of fatigue failure in punching shear of reinforced concrete decks of highway bridges is analytically investigated by applying Matsui et al.'s experimental finding to models of 2-meter span decks designed in compliance with previous and current codes. Decks made of concrete of compressive strength of 240㎏/㎠ showed longer fatigue life than decks made of 210㎏/㎠ concrete at the same Md/U rations ; higher Md/U ratio resulted in linger fatigue life but its effect is insignificant in decks having effective depths of 14 and 15cm. Decks designed to higher load factors as specified by current codes showed longer fatigue life than decks designed to lower load factors specified by previous codes ; yet fatigue failure appeared to occur in both decks within their normal life span, thus indicating need for redefining the minimum deck thickness.

RFID(Radio Frequency IDentification) is a method of remotely storing and retrieving data using devices called 'RFID tags'. An RFID tag is a small object, such as an adhesive sticker, that can be attached to or incorporated into a product. RFID tags contain antennas to enable them to receive and respond to radio-frequency queries fro an RFID transceiver. Eventually, RFID SYSTEM is very interesting to watch people live linger than they used to before. Some of reasons for that phenomenon is the improving medical studies. As we live healthier and get to know more about our body, we can extend our lives. This Platform is Physical Health Promotion Service, Home Health Monitoring Service, Mental Health Promotion Service, Home Patient Management Service, Chronic Disease Management Service, Emergency Patient Management Service, Medical Information and Consulting Service of the RFID.

Effect of hand-transmitted vibration on human discomfort and health was reviewed. Since the effect by hand tool was more serious than those by any other vibration environments, western countries have protected hand tool workers by regulations. International organization for standardization legislate standard, ISO 5349, at 1979 for the measurement and evaluation of the effect. Afterwards, more than twenty standards on hand-arm vibration were enacted to Protect any damage of hand tool users. Even though Korea Standards adopted ISO 5349 in 2001, it is required an action plan should be applied to all of work environments, especially to the workers using pneumatic tool workwers such as miners, construction workers, and etc.

Introduction : Exercise has been suggested as an important nursing strategy in which to help elderly maintain functional performance and to enhanced quality of life. Most of exercise study has been reported on fitness exercise such as walking, swimming, dance etc for health of elderly. There have been few reports about exercise on the promotion of small and fine movement of elderly. The purpose of this pilot study was to determine an effect of 6 weeks hand and finger exercise in home to improve hand muscle strength such as grip strength and finger pinch pressure. Materials and Methods Design: This pilot study was used one group pre and post-test design. Sample: Twelve elderly women above 60 years of age or older living in community were selected by convenient sampling. Procedure: Signed informed consent was obtained prior to participate in this study. The authors met elderly and taught hand and finger exercise, daily a week for 6 weeks, within 30 minutes per session. But exercise frequency and strength were not same. Instruments: Left and right grip strength were measured by Bulb Dynamometer(made in USA) and left and right pinch pressure were measured by Baseline Hydraulic Pinch Gauge(made in USA). Data analysis: Discriptive data analyses were performed on all variables. Wilcoxon matched-pairs Signed-Ranks test were used to find difference of grip strength and pinch pressure between pre and post exercise using SPSS 10.0 for Window. Results: Samples age ranged from 60 to 73, Mean age was 65.3. All were women. Ten elderly were diagnosed osteoarthritis and one had DM. After six weeks hand and finger exercise, Left and right grip strength were higher than those of before exercise(Z=-2.667, P<0.01 ; Z=-3.065, p<0.01). And left pinch pressure after hand and linger exercise were higher than that of before pinch pressure (Z=-2.315, p<0.05). But Right pinch pressure was not shown significant change(Z=-1.099, p>0.05). Conclusions: Although this study was limited by the sample size and design, the findings provide some important implications for community based exercise nursing intervention. Short term (six weeks) exercise of hand and linger is shown to be useful as nursing intervention to maintain routine daily activities such as eating, writing, grip something for elderly.

Recently, the Ministry of Employment and Labor Management is a trend to strengthen all men death rate than the accident rate. Points reduction in the accident rate change orders related to credit rating score to +2 points in his plans as part of +1 point. In addition, according to the fancy linger RISK treatment in the event of a disaster site and fiction treatment to achieve accident-free during processing the scene interspersed with equity issues have been raised. In general disaster for the problem in the first two cases occurs when abnormal process according to the disaster site manager positions dismissal policy, each division headquarters itself, interspersed disasters performance compared to processing in accordance with the refrain, processing expenses in accordance with the composition of untreated industrial accident, costs and burdens partners FTC, there is a possibility that the issues raised, such as the Ministry of Employment and Labor. In response to domestic social practices focused on the construction site practices and prevention measures should be evaluated with respect to what.

There are three things that are not known to the human being. That is when, where and how one will die. Most people live ignoring death. However, elements of death linger everywhere. The purpose of this treatise is investigates about justification Deciding for Other directions. First, I will investigate about Deciding for Other directions, when patient can not decide own, I will do investigate agent's decision's problem. Second, These four principles provide the common ground for biomedical ethics. Principlism argue that a method using four principles can resolve controversies in bioethics. The method holds that there are four principles-respect for autonomy, nonamleficence, beneficence, justice- that articulate the necessary conditions of common morality for health care and bioethics. Beauchamp and Childress respond by arguing that the two problems are nc the meaning or interpretation but the process of specification. Third, So, Supplement four principles' problem to Levinas concept of the Other theory. Levinas concept of the Other is very resemblant with 'Love your neighbour as yourself." Christians believe that Love is above all and they act accordingly. They base this faith mainly upon the motto of "love your neighbour as yourself." Fourth. difficult part of Levinas concept of the Other is that there is no human to equal infinite sense of responsibility. Can be supplemented about this through cooperation of community. Four principles can be brought to bear on moral choices. And they asserts that each principles has weigh but they do not assign a priority weighting of ranking. All the principles are equal in moral decision making.

수액은 일반적으로 환자에게 특정 주사를 일정 시간동안 주입하기위해 사용되어진다. 환자나 보호자는 수액의 투입종료 시점을 예상하여 의료진을 호출하여야 하는 경우가 많고, 취침시간 등 특정 시간에 수액투여가 종료될 경우 환자나 보호자에게 더 많은 피로를 줄 수 있다. 또한 의료진은 수액의 투입종료시점을 확인하기 위하여 몇 번이고 현장에 찾아가 수액의 양을 모니터링 해야 하는 수고로움으로 업무의 비효율성을 가져올 수 있을 것이다. 본 논문에서는 이러한 문제를 해결하기 위해서 수액의 수위를 감시하는 최소한의 장비와 능동형 RFID를 결합한 형태의 위치기반 서비스 시스템을 제안하고, 환자별 수액의 양과 환자의 위치를 실시간 파악하여 환자나 보호자 또는 의료인(간호사)에게 정확한 정보를 제공하여 수액 투여가 마무리될 시점에 의료진이 환자의 위치로 찾아가는 서비스로 의료서비스의 질을 향상시킬 수 있을 것으로 기대한다.

표면 근전도 신호를 이용하여 손가락의 굽힘 동작을 추론하는 방법을 제안한다. 표면 근전도 신호는 인체 근육의 표면에서 무해하고 손쉽게 취득되나, 전극이 근육 내부에 침투하는 침습식 근전도와는 달리 특정 근육의 활동만을 반영하지 않는다. 따라서 소수의 전극을 사용하는 표면 근전도 신호로 다양한 신체 동작을 구분하기는 쉽지 않다. 본 연구에서는 전완 둘레에 부착된 4채널 근전도 센서를 사용하여 신호를 취득하였고, 구분을 위하여 사용한 동작은 엄지, 검지, 중지, 약지, 소지의 개별 손가락의 굽힘 동작이다. 피검자 한 명은 숙련자였으며, 다른 한 명은 비숙련자였다. 근전도 신호의 특성으로 정보 엔트로피를 추출하였으며 최대우도추정법을 사용하여 실제 동작을 추정하였다. 실험 결과 평균 95% 이상의 성능을 보였으며, 제안하는 방법이 손가락 동작의 구분에 유용함을 확인하였다.
