Databases are central to business information systems and RDBMS is most widely used for the database system. Normalization was designed to control various anomalies (insert, update, delete anomalies). However, normalized database design does not account f

Manual tracking is an experimental paradigm that can be used to study information processing in continuous movements involving accurate, ongoing control of motor performance. The purpose of this study was to identify the effects of knee tracking training, using the paretic side, on gait in stroke patients. Nine patients with hemiplegia participated in the study. The timed 10 m gait speed test and tracking test were administrated. The tracking test was composed with ranges of to and to . The tracking training consisted of five times every week for 4 weeks. The data were analyzed by non-parametric paired sign test of Wilcoxon. The flexion/extension error of the tracking test was significantly reduced on the paretic side, while the nonparetic side was not statistically significant. The transfer of the skill to the functional activity was shown in the significant improvement at timed 10 m gait speed test. This study shows that individuals with chronic who have impaired knee movement can be trained to improve their knee control through intensive practice at a knee movement tracking task and that the skill learned from such training is transfered to a more functional gait speed.

It was general that WSD, USD, LSD etc. used in old do not consider area situation of each country and environment differences. But if concept of PBD which is supplement shortcoming of old design method and optimized design is introduced construction could be designed economical and plan systematically. It is purposed that this paper informs explanation and present condition for material and construction part of Asia Concrete Model Code. Also PBD design details which is suitable in comprehensive substance will be presented later.

본 연구에서는 공주대학교 천문대 16인치 반사망원경의 원격 제어 시스템을 구축하였다. 이 시스템은 닫힌 루프 시스템이다. 전자제어부는 한국천문연구원에서 개발한 TCS-196를 활용했고, 기계부는 직접 개발하였다. 이 원격제어망원경의 마운트 모델링 후 얻은 지향정밀도는 시간각 방향에서는 ±50", 적위 방향에서 ±40"이며, 추적 정밀도도 약 1"/min정도였다. 이러한 예비관측 결과는 본 시스템이 천문학 연구 및 교육에 적당함을 의미한다.

극지 환경계에서 발견되는 수은의 농도분포는 봄철 극단적인 소멸과 여름철 고농도의 발현과 같이 특이한 분포 특성을 취하는 것으로 밝혀지고 있다. 이와 같은 극지환경의 계절적 농도분포특성은 일반적으로 알려진 수은의 대기환경학적 특성과 상치되는 현상이다. 본문에서는 북극지역에서 장기간 관측된 수은의 농도자료와 이에 대비한 비교 자료 군으로 서울지역을 중심으로 장기 관측된 자료들을 동시에 이강하여, 극지역 수은분포의 특이성과 환경학적 의미를 여러 가지 관점에서 다양하게 고찰하였다.

The purpose of this study is to examine the effects of utilizing concept maps in a rock-related unit. To do this, two groups composed of 73 sixth grade students engaged in this study. One group (experimental group) participated in utilizing concept maps in the unit, the other (control group) took part in traditional instruction in the same unit. The results of this study are as follows, after seventeen sessions: First, the achievement between the two groups showed significant difference. It indicates that utilizing concept maps as an instructional method is effective. Second, in the examination of the experimental group's attitudes toward concept maps, the students showed more affirmative responses on cognitive items than on affective items. Third, the students showed that they have difficulty in the method and the procedure of drawing up the concept maps. It indicates that the method and the procedure are sufficiently learned before instruction begins.

The purposes of this study were to investigate the customers' perception on nutrition information provided on a family restaurant menu, to examine customers' intention to use the nutrition information when eating out if nutrition information would be provided, and to identify what kinds of nutrient information the customers want. A total of 265 respondents were answered. Female was sixty-six percents, and eighty-four percent of the respondents was less than thirty-five years old. The patrons' perception about nutrition information on the menu showed the level of 2.5 points out of 5 points, which pointed out that family restaurant patrons were not satisfied with receiving nutritional information related to the menu. The customers perceived that restaurants had responsibilities for providing nutritional information about menu items. Sixty-six percent of respondents showed a positive intention to the question item about how much the customer would use nutritional information provided on the menu. The customers, who were female (p<0.05), who had a good health status, who showed higher interest on weight control (p<0.01), and who were health-oriented (p<0.01), showed the higher intention to use nutritional information. Nutrient information in which the customers were interested strongly was a fat content, followed by cholesterol content and calorie information. According to the trends of eating out, preferring family restaurants, and increasing interests in a healthful menu, nutrition information demand in restaurant operations would be increased rapidly in the near future. Providing nutrition information at the point of menu choice might result in the improvement of customers' nutritional and health status by encouraging proper dietary habits of patrons as well as providing nutritional education. Therefore, it is recommended that government and restaurant firms should recognize the importance of nutrition information and make strategic plans for the future.

Lecture Evaluation system is an only way, so far, to evaluate the quality of lectures in our university and yet has several problems. This system does not have any effects on professors; however, it is rather used to threaten assistant professors and/or part-time/full-time lecturers. As a result, students are still dissatisfied with the unchanging lectures of professors. Generally speaking, We should consider new ideas to introduce a head teacher system or improve the lecture evaluation system to open doors wider for teachers, professors do their best to expand students' understanding by practicing the Lecture Evaluation System. In fact, it is hard to keep the objectiveness that the professors estimate the quality of professors. That is why this check list should be restricted only as a guideline among the system. After all, it is expected to bring better educational circumstances when the system functions properly to provide professors to research more.

In 21st century, According to development of Information Technology, It is clear that the importance of tourism information is extended increasingly. For this reason, It should be needed to realize a general system which make it possible to enjoy cyber tourism based on knowledge information system to recover a local potential growth power, catch a jumping chance again, and hold a new competitive power. But to discuss a tourism information system, the matters of hard ware, software and information mediating system should be reviewed generally, this research is likely to provide a cyber tourism information system through internet as a way of cyber tours through multimedia technology and stereoscopic image technique using GIS (Geographic Information System) centering on the networking system of tourism information. Constructing 「cyber touristy city」 on internet, foster a new industry, to go balanced with a present tourism industry and experience a virtual reality, various theme tours create high profit to shrunken tourism industry.

샌드위치 판은 질량에 비해 높은 강성과 강도를 갖고 있으므로 매우 효율적인 구조재로서 폭넓게 쓰이고 있다. 알루미늄 압출 샌드위치 판의 적절한 설계를 위하여는 역학적 거동 해석이 선행되어야 하나, 아직 이에 대한 연구는 미비한 상태이다. 코어가 채워져 있지 않은 중공 단면(hollow section)인 샌드위치 판의 역학적 거동 해석에는 일반적으로 상세 유한 요소 해석을 하게되나, 이는 모델링과 해석에 많은 시간이 소요된다. 본 논문에서는 트러스(truss) 형상의 심재를 갖는 샌드위치 구조 압출재를 이방성의 판으로 치환하여 해석하는 방법을 제시하였다 적절한 이방성 후판으로의 치환을 위해 등가의 강성을 평가하는 방법을 제안하였으며, 이 등가의 강성을 판 이론에 적용하여 균일 분포 하중을 받는 사변 단순지지 조건의 알루미늄 압출재에 대한 처짐과 응력에 대해 간이 해석식을 개발하였다. 아울러 상용 유한 요소 프로그램을 이용하여 계산한 결과와 비교한 결과 제시한 간이식의 높은 정도와 효율성이 입증되었다.
