본 논문에서 제시한 32비트 테스트 코어는 기존의 ARM과 같은 32비트 RISC 코어를 대신하여 JTAG 및 코어브레이커의 회로 테스트를 위하여 고안되었다. 테스트 코어는 디버깅유닛을 바꾸어가며 재이식(retargetable) 가능하게 사용될 수 있다는 장점을 갖는다. 회로 합성 결과 하드웨어는 ARM과 비교하여 33% 정도의 게이트를 가진다. 테스트 코어는 보다 높은 디버깅 성능을 위해 다중로드(multiple load; LDMA)와 다중저장(multiple store; STMA)명령을 추가하였으며 단일로드(single load; LDR) 또는 단일저장(single store; STR)명령들에 비해 64% 정도의 처리시간 단축을 나타내었다. A 32bit RISC type core is designed to replace full processors for testing JTAG and core breaker modules. It is retargetable and can be utilized to test a debugging unit. The design uses about 33% of gates with respect to a fully designed ARM7. It has instructions, multiple load or store(LDMA, STMA), for debugging purposes. Simulation result shows that they reduce the execution time about 64% with respect to processors having a single load or store(LDR, STR) instruction.

It has been reported several viral diseases in soybean. The occurrence of Bean common mosaic virus and Peanut stunt virus are able to induce severe problem because the main breeding target for viral disease was focused on Soybean mosaic virus. BCMV is a spcies of the genus Potyvirus of the family Potyviridae. BCMV reduces yield by as much as 80% and also adversely affects seed quality in common bean. BCMV has a worldwide distribution because of its high rates 35% of transmission via seeds produced by plants systemically infected prior to bloom. PSV is a species of the genus Cucumovirus of the family Bromoviridae. PSV has been reported to be economically damaging on beans worldwide. Although the virus is reportedly seed transmissible at very low rates, infected plants rarely produce pods with normal viable seeds. The most satisfactory management method of viral diseases such as BCMV and PSV is the use of resistant cultivars and healthy seed. For the overcome of genetic resistance by new virus such as BCMV and PSV, virus diseases monitoring and researches need to study deeply and continually. In this study, we conducted the resistance screen on BCMV and PSV for selection of resistance cultivars. We inoculated on 128 cultivars with PSV and BCMV respectively. These cultivars were classified through pathogenic response such as resistance, necrosis and susceptibility. In addition, 99 and 66 resistant cultivars were confirmed against PSV and BCMV respectively.

This study investigates changes in cooling efficiency for heat sink plate width, perforated width, and chamfer angle as part of a parameter study to maximize cooling efficiency of heat sink by setting various variables on plates. The width of the plate is set to 16, 20, 24, 28 mm, perforated width 1.5, 2.0, 2.5 mm, chamfer angles 5, 10, 15 and 20°. By conducting a computational study with Ansys Fluent, the sink plate with plate width of 16mm, perforated width of 3mm and chamfer angle of 10° is shown to be the best cooling efficiency.

Purpose : The purpose of this study was to identify needs of health education of the students, parents, general teachers, and health teacher of the elementary, middle, and high schools. Method : 279 schools of elementary, middle, and high school were sampled nonproportionally during the period from June 28 to July 26, 2004 . The data were collected by the questionnaire from 1,888 students, 1,876 parents, 1,695 general teachers, 279 health teachers. A frequency, % and χ2-test were used to analysis by SAS program. Result : 1. It showed that 98.1% of elementary school students, 92.3% of middle school students, 89.6% of high school students answered that they need health education. The most of students, parents, and general teachers had high interests in health education. 2. In the case of students, main causes of needs of health education was 'to prevent diseases or accidents''. But parents answered that it was 'to build up a healthier behavior'. General teachers answered that it was 'more effective systematic and continuous health education'. 3. Over 80% of students, parents, and general teachers about the question of who qualified person is to teach health education as a regular class responded that health teacher is available. Especially 93% of elementary school students answered like that. 4. The most of students, parents, and general teachers answered that health education in the classroom is favorable 1 to 2 hours per week. Conclusion : As results of the study , the majority of students, parents, general teachers agreed needs of health education. Therefore, on the basis of this study, systematic and continuous health education is necessary. Additionally the establishment of independent health subject is required certainly.

While most of adults in the past thought that marriage was compulsory, now marriage is considered not as compulsory but as optional, which is being on a decreasing trend. Accordingly, their intention to marry, time and motive of marriage depend on the individual situation or preference rather than the standardized and uniform way. This study was conducted to analyze the intention of unmarried men and women to marriage more concretely and in depth. The survey of 316 students who took a course of 'Marriage and Family' in Chung-Ang University was conducted with a way of self-description as a method for a qualitative survey to analyze their consciousness to marriage more deeply, classifying into a total of four questions. The findings of the survey were as follows. First, in terms of the intention to marriage, 93.0% of the responders answered "I will marry", indicating the majority of the students were considering marriage positive. In addition to it, in terms of the connection of love and marriage, 61.0% of the responders answered love and marriage were connected with each other, compared to 34.0% who answered seperate. Second, in terms of the motive of marriage, realization of love topped, followed by a valuable thing, emotional stability, providing for their old age, economic stability, independence from their parents and happy married life of their parents. Third, in terms of the reason to choose single, freedom topped, following by concern at change of love, unnecessity of marriage, burden on a new family, negative image to marriage, description and escape from reality, economic responsibility and the cumbersome processes of marriage.

In this paper, the 3-bit phase shifter using the series-coupled PIN diode to decrease the insertion loss is designed at WLL frequency bandwidth. The 30˚ bit and the 60˚ bit phase shifter are designed by the loaded-line type which is easy to obtain a small shift angle and the 90˚ bit phase shifter is designed by the reflection type obtaining a large shift angle. The 3-bit phase shifter is combined with the series connection of each bit phase shifter by the increasing arrangement of phase shift angle. From the results, the designed 3-bit phase shifter shows that the phase difference of input signal is shifted every thirty-degree intervals at output port. The average value of phase error is 0.53˚ , maximum phase error is 1.18˚ , and the insertion loss is 0.840dB~1.335dB at center frequency (2.315GHz).

Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.
