스마트 기술의 도입은 의사와 환자 모두에게 정확성, 안전성, 효율성을 제공한다. 투명 교정장치에 대한 관심은 국내외에서 점점 높아지고 있지만, 현재 투명교정 장치로 치열교정을 할 경우, 환자는 1, 2주에 한 번씩 병원을 방문하여 교체하여야 하며, 약 40~80개 정도의 장치가 제작되고 교정장치의 착용 순서 및 기간 등을 고려해서 교정이 이루어지기 때문에 치과 의사와 환자는 매우 번거롭고 혼란스럽다. 또한 이 과정에서 치과 의사와 환자 간 정확한 의사소통이 필요하다. 따라서 본 연구는 투명 교정장치에 QR 코드를 삽입하여 환자와 의료진 간의 커뮤니케이션이 보다 원활하게 이루어질 수 있도록 투명 교정장치 관리 시스템을 설계 및 개발하였다. 개발 결과 QR 코드의 크기는 구강 내에서 사용 가능한 $6{\ast}6mm^2$ 이상이면 100% 인식하였고, 인식 거리는 12cm 이내에서 100% 인식률을 보였다. 제안한 시스템으로 치과의사는 환자를 원격으로 관리하며 교정효과를 높여 주기 때문에 국내의 환자는 물론 해외의 환자 관리가 가능하다.

A coupling system of MM5 and POM using Stampi with different kinds of parallel computer is proposed and comparative numerical simulations of mesoscale wind induced by topography around East Sea/Sea of Japan are carried out. The results are as follows： 1) Strong horizontal conversion is induced by high mountain Pekdoo at its leeside. 2) The conversion winds at lee of high mountain are not clear in monthly and yearly mean NCEP-reanalysis because of coarse resolution of 1.86 degree by 1.86 degree. But Wind conversion is well simulated at atmosphere and ocean coupling system. And the conversion area of lee side of mountain is also agreed well with observed data of NSCAT launched in satellite ADEOS. 3) The surface ocean current is well correspondent with wind direction, induced by high mountains. And small different wind field information lead the different of particle distribution in numerical experiments of particle distribution on ocean surface.

Nursing's traditional concern for human well being includes concern for health promotion. Until recently textbooks of preventive medicine, public health and community health nursing have defined health prevention- the prevention of disease and health protection or maintenace, but not health promotion. Lack of clear definitions inhibit effective communication among health related disciplines. Therefore, this studys task was the analysis and definition of the concept of health promotion using Walker & Avant's concept analysis methodology. This characteristics of the concept of health promotion are 1) orientation toward well - being, 2) empowering, 3) subjectivity, 4) change and 5) expanded connecteness. Antecedent of health promotion are 1) attaining of a healthy state, 2) having purpose and will to act, 3) persistent and realistic behaviour. The consequences of health promotion are 1) prolonged life, 2) self-actualizing potential, 3) increased well-being and a high level quality of life. The future direction of health promotion research should include that identification of the differences in the definition of between health professionals and health clients and research related to nursing theory of health promotion.

The nondestructive internal quality evaluation of agricultural products has been strongly required from the needs for individual inspection. In recent, ultrasonic wave has been considered as a solution for this problem. It transmit well through most materials and can handle safely and easily. However, specially in a watermelon, it is known that general frequency band (higher than 20kHz) ultrasonic waves do not transmitted well due to severe attenuation. The objectives of this study were to find out the proper waveform and frequency of the ultrasonic waves that transmit well inside the watermelon, and to analyze the transmitted waveform in order to make clear the structure of wave propagation in watermelon. The result of several experiments showed that 2kHz shear wave was the most suitable for the detection of internal cavity in the watermelon. Also, it was found that the surface wave did not influence the directly transmitted bulk wave. These results could be a basis of application of ultrasonic wave on the evaluation of internal quality of the watermelon.

Interdisciplinary research is one of the well-known key words represent the 21st century As in the developed countries, interdisciplinary research is a pervasive phenomenon in Korea. This paper intends to clear up the interdependent structure among disciplines of university researches. First, 39.9% of individual and 59.8% of collaborative research projects of university researches are interdisciplinary. Second, the interdependency among disciplines of collaborative research is more severe than that of individual research. Third, The interdependency among disciplines indicates tile importance of the balanced development in all science and engineering fields.

Main purpose of this paper is to describe what is radwastes and spent fuel of radioisotope and nuclear power plants. Although this term is well adapted among the people nowadays but it is necessary to know more clear definition in accordance with atomic energy promotion law. By various means of scientific knowledge and engineering techniques, we can shield harmful radiation from radwastes and spent fuel, also could know how we can take benefits from radioisotope applications for human health care and other applications. It is realized that problem of spent fuel is not easy task to solve at the moment because we have to consider many sides.

The authors tried to make experimentally clear the response of engine speed to stepwise increasing, decreasing or sinusoidally fluctuating load. Based on a simplified model devised from the standpoint of the control theory, analysis was carried out with digital computer and its results obtained coincide well with those of experiment, so that it could be confirmed that it is possible to simulate the speed response to variation of the load.

Code and object reuse is big concern for fast and efficient Virtual Reality (VR) system development. Many VR packages offer reasonably nice abstractions for various functionalities. That is, software reuse at the functional level is well practiced. Many geometry models are rarely used for main \"characters\" but mostly for incidental and decorative objects. This is because the main \"character\" objects usually exhibit certain behavior incompatible with the way the geometric model is organized. Kim has made a clear distinction between form, function and behavior[1]. This naturally lends to a reuse method at the level form, function and behavior.nction and behavior.

This paper intends to clear up the conte31t of the interdisciplinary nature of individual researches. First, the interdisciplinary character of individual research was analyzed. Approximately 40% of individual research projects supported by Korea Science and Engineering Foundation has the interdisciplinary nature. Second, there are close connections among research fields in individual research projects. Every research field needs the inflow of knowledge from other fields and supports other research fields as well. The interrelation among various research fields indicates the importance of the balanced development in all science and engineering fields.

In order to simulate a robot by using existing simulation packages, many engineers must work in one place existing simulator. It is clear that engineer can't the simulator in other place. In this paper, a simulator by using a web environment is proposed in order to support location transparency to engineer. The proposed simulator running in the web browser. This simulator can be use the engineer as well as public user through web browser.
