Objective: The purpose of this study was to understand the injury mechanism and to provide quantitative data to use in prevention or posture correction training by conducting kinematic and kinetic analyses of risk factors of lower extremity joint injury depending on the change of direction at different angles after a landing motion. Method: This study included 11 men in their twenties (age: $24.6{\pm}1.7years$, height: $176.6{\pm}4.4cm$, weight: $71.3{\pm}8.0kg$) who were right-leg dominant. By using seven infrared cameras (Oqus 300, Qualisys, Sweden), one force platform (AMTI, USA), and an accelerometer (Noraxon, USA), single-leg drop landing was performed at a height of 30 cm. The joint range of motion (ROM) of the lower extremity, peak joint moment, peak joint power, peak vertical ground reaction force (GRF), and peak vertical acceleration were measured. For statistical analysis, one-way repeated-measures analysis of variance was conducted at a significance level of ${\alpha}$ <.05. Results: Ankle and knee joint ROM in the sagittal plane significantly differed, respectively (F = 3.145, p = .024; F = 14.183, p = .000), depending on the change of direction. However, no significant differences were observed in the ROM of ankle and knee joint in the transverse plane. Significant differences in peak joint moment were also observed but no statistically significant differences were found in negative joint power between the conditions. Peak vertical GRF was high in landing (LAD) and after landing, left $45^{\circ}$ cutting (LLC), with a significant difference (F = 9.363, p = .000). The peak vertical acceleration was relatively high in LAD and LLC compared with other conditions, but the difference was not significant. Conclusion: We conclude that moving in the left direction may expose athletes to greater injury risk in terms of joint kinetics than moving in the right direction. However, further investigation of joint injury mechanisms in sports would be required to confirm these findings.

In order to provide a desirable direction for the health education on preventing drinking of elementary school students. by understanding the views held by elementary school teachers on drinking prevention education. 529 teachers at elementary schools located in Seoul were responded by constructed questionnaires during the period of Nov. 15 to Dec. 18 1999. The results of the survey analysis were as follows: 1. $84.6\%$ of the respondents said that schools should offer education programs on preventing drinking, and this view was more strongly shared by teachers with religions than non-religious ones. 2. $35.0\%$ of teachers responded that the education should start with 6th graders, while $28.3\%$ opted for 4th to 5th grades. With regard to the appropriate class in providing such education, $41.0\%$ selected physical education (PE), followed by extracurricular activity class with $35.4\%.\; 45.6\%$ of the respondents said discussion would be the most effective education method. while $35.4\%$ recommended using experiments. Growth and developmental defect and fall in diseases were pointed out as the most interesting topic for students by $39.4%$ and $31.2\%$ of the surveyed, respectively. As for the most effective media for education, $56.0\%$ recommended video, followed by cartoons $(21.5\%)$ and computer games $(19.5\%),\;63.7\%$ of the teachers picked school nurses as the most appropriate person in carrying out the education. The results of the finding show that it would be most desirable to provide health education on preventing drinking to senior elementary schoolers during the PE or extracurricular activity class by school nurses. The program would be structured to first show video clips on growth and developmental defect or fall in diseases resulting from drinking and to have discussions or experiments on related matters.

Today, it is a fact that interior design plays a very important role as much as architecture on contributing to our society as a rising new professional field. On the other hand, our interior design education is still in immagture stage unlike the graudal development of the mood of interior design line , If the interior design field has any educational value to invest to be noticed as an environmental design that creates the human environment. There are great deal of meanings to indicate the direction for better education after recognizing the manu different problems on presently offering interior design education. Therefore, the objectives of this study is , after establishing the innovative methods of education and course contents of the four year interior design program, to produce the interior designers of manifold abilities, who is able to fit well in the professional practice, in order to materialize the settlement of interior design education which will be the key point in our circumstances, which has ow social recognition toward interior design. There were four phases in this study. First was to gather and to analyze information from printed materials, such as curriculum and catalog from each institution. Secondly, we had collected existing previous studies in all interior design area in order to sude as references. Thirdly, we have managed to suggest ideal improvement for better basic design program in the area of interior design education after the arranging and analyzing . Finally, we were able to persuade the importance of improved basic design program to the interior design education parties and to suggest the direction for the future. Because interior design as a scholastic pursuit is combined practical application study by the art and technology, it emphasizes specialty . From that reason interior design education must be performed as professional specialist education instead of vocational education. In another words, the ultimate goal of the interior design objectives must be in producing professional specialist.

A two-direction multiscaling function ${\phi}$ satisfies a recursion relation that uses scaled and translated versions of both itself and its reverse. This offers a more general and flexible setting than standard one-direction wavelet theory. In this paper, we investigate how to find and normalize point values and derivative values of two-direction multiscaling and multiwavelet functions. Determination of point values is based on the eigenvalue approach. Normalization is based on normalizing conditions for the continuous moments of ${\phi}$. Examples for illustrating the general theory are given.

This study conducted a survey and investigated students' opinions and design preferences to physical education (PE) uniforms for elementary, middle and high school students using PE uniforms for the following purposes: to increase satisfaction with PE uniforms; present basic data for the development of PE uniforms helping to improve the quality of school life; and propose the development direction of PE uniforms. PE uniforms shall be developed with the components of uniforms, symbolism, functionality and aesthetics. The symbolism of PE uniforms expresses the affiliations of people wearing them and makes them have a sense of affiliation. The functionality presents convenience in students' physical activities and intramural/extracurricular activities. The aesthetics reflects the aesthetically sophisticated sport wear trend in PE uniforms. The development direction of PE uniforms was organized based on the result of analyzing and investigating students' opinions and design preferences to PE uniforms. There were differences in students' opinions and preferences to PE uniforms according to the type of student groups (elementary, middle and high school). In addition, there were clear gender-differences in the same student group. An effort might be required to reflect students' preferences because PE uniforms which students had currently worn at school had been manufactured without the reflection of students' opinions.

CW 레이더 센서는 IF 출력 방식에 따라 단일 IF 방식과 이중 IF 방식이 있다. 움직이는 물체의 방향을 검출하기 위해서는 이중 IF 방식을 사용한다. 하지만 이중 IF 방식은 단일 IF 방식에 비해 회로가 복잡하며 부품 추가로 인해 가격이 높아진다. 본 논문에서는 단일 IF 방식 CW 레이더 센서에서 움직이는 물체의 방향을 검출할 수 있는 알고리즘을 제안한다. 물체가 움직일 때 발생하는 IF 출력단의 신호를 FFT를 수행하고 진폭의 변화에 따라 접근/정지/이탈을 판단한다. 알고리즘의 검증을 위해 함수발생기를 사용하여 가상의 신호를 발생시키고 신호의 진폭 변화에 따라서 방향을 정확하게 판단하는 것을 확인하였다.
