In mold structure machining, tool interference is a phenomenon which results from a collision between a blade of tool and a workpiece. Also tool collision is a phenomenon which results from a collision of holder with the object to be machined. These phenomena not only cause damages to mold and tool but also increase machining time and cost. To detect a collision of a tool to mold structure, first of all, the mold structure and a tool must be defined with famous geometric models such CSG, B-rep, and Voxel. A tool is defined as a combination of the blade, the shank, and the holder. This thesis reviews various collision detection algorithms using z-map and computer 3D graphic collision detection algorithms for the tool in machining a mold structure.

Consumers keep demanding for diversified high quality products, valuable services and safety. With this in mind, Distribution Industry is being updated rapidly to accomodate this demand. Meanwhile, Distribution Information Technology of agricultural products has been in slow progress with little in-depth studies. In this study, it has been analyzed the usage of Bar code which is the key element for agricultural Distribution Information Technology. The analysis was conducted through a survey utilizing questionnaire covering 5 Hypermarkets(Super-centers) including big 3 companies. Also, Japanese market trends have been studied to visit a Japan Government Organization concerned, GS1 Japan, an Agricultural Cooperative, an Agricultural Wholesale Market, and a Retail Company. If we could use KAN code for all agricultural products, we could collect and analyze the information of price and trade quantity of them. It opens a new era to understand the agricultural products supply and demand easily. This will certainly make a great contribution to the evolution of agricultural products distribution. From this research, it is suggested that collective efforts by suppliers, wholesalers, retailers and Government Officers are needed to make large scale mutual marketing Organizations, which specialize in sending out agricultural products. The Organization is recommended to standardize and pack every final agricultural products, to promote the use of KAN code.

트리구조로 명명되는 '위계'는 정보의 구조를 드러내 보이고 복잡성을 감소시킬 수 있기 때문에 시각화하는데 매우 유용한 자원이다. 본 연구는 멀티미디어 환경에서 위계의 개념을 적용한 정보 시각화 방식에 대해 고찰하였고 나아가 그것이 정보 찾기 활동에서 사용자태스크 유형과 어떻게 연계되는지를 파악하고 그 활용 가능성을 탐색하였다. 본 연구에서는 트리맵(Treemap), 하이퍼볼릭(Hyperbolic), 콘트리(Cone Tree), 관심도트리(Degree-Of-Interest Tree)의 4가지 정보위계 표출방식을 적용 사례별로 고찰하고 그 활용상의 장단점을 '시각적 재현 측면'과 '사용자 조작 측면'으로 나누어 제안하였다. 또한 각각의 정보위계 표출방식에서 사용자 정보 찾기 활동과 결부된 '핵심 지원 태스크'와 '주요 관련 지원 태스크'가 무엇인지를 구체적으로 제안하였다. 본 연구를 통한 주요 발견 점은 첫째, 사용자의 정보 찾기 활동과 결부된 주요 지원 태스크는 전체를 총괄적으로 조망하기, 관심 있는 대상을 확대해서 보기, 관심 없는 대상을 걸러내기, 특정 대상에 대한 세부적인 디테일 정보 얻기, 정보 객체 사이의 관계 파악하기, 발생한 이벤트의 히스토리를 유지하기, 수집된 정보를 추출하고 발췌하기 등이다. 둘째, '트리맵'은 사용자에게 전체 정보 그룹에 대한 총체적 의미 파악이 용이하도록 만들기 위해서 각각의 정보 노드의 색상과 크기를 다르게 적용시키는 방식을 핵심지원 태스크로 적용하고 있다. '하이퍼볼릭'과 '관심도트리'는 사용자가 선택한 특정 정보 노드를 중심으로 전체 정보 그룹을 재편성시키거나 의미의 중요도에 따라 각각의 노드 크기에 비례 개념을 적용시키는 기능을 핵심적으로 지원하고 있다. '콘트리'는 정보에 접근한 사용자 로그파일을 발췌하고 분석하여 정보 관리자가 전체 정보 패턴을 분류하고 조직화시킬 수 있도록 하고 있다. 결론적으로 멀티미디어디자인 환경에서 정보위계 표출방식은 정보의 시각적 재현이라는 차원을 넘어 사용자의 정보 찾기 행위와 관련하여 사용자 조작의 다양한 기능적 욕구를 반영하고 있음을 본 연구를 통해 파악할 수 있었다.

Theoretical framework of motor learning is used to enhance perceptual motor skill in physical therapy intervention, which can be subdivided into two main types-explicit and implicit. The purpose of this study was to examine whether stroke patients with unilateral brain damage learn implicitly a motor skill using the arm ipsilateral to the damaged hemisphere. Speculation then followed as to the formation of therapeutic plans and instructions provided to patients with stroke. 20 patients with stroke and 20 normal participants were recruited. All the subjects practiced serial reaction time tasks for 30 minutes a day and retention tests on the following day. The tasks and tests involved pressing the corresponding buttons to 4 colored circles presented on a computer screen as quickly and accurately as possible. Patients with stroke responded more slowly than controls. However, both groups showed decreased reaction time in the experimental and retention periods. Also, there was no significant difference between both groups regarding explicit knowledge of consecutive order. Therefore, patients with stoke had the ability to learn implicitly a perceptual motor skill. Prescriptive instruction using implicit and explicit feedback may be beneficial for motor skill learning in physical therapy intervention for patients with brain damage.

The purpose of this study was to research eating-out information search methods according to college student's lifestyle and their influences on overall satisfaction at fast-food restaurants in eastern province of Kangwondo. Lifestyle was divided into 7 factors and 6 clusters. According to the results, information search methods through Newspaper, magazine and word of mouth were used the most preferably by Cluster 3, 'Brand preference intention'. And TV advertising was used the most preferably by Cluster 4, 'Convenience intention', and the advertisement through internet was used the most preferably by Cluster 5, 'Health · effort intention'. However, Information searches through TV advertising and word of mouth had negative influence on the overall satisfaction. But method through internet had positive influences on the overall satisfaction. Eventually, it's proved that information search methods had significant differences according to student's lifestyle. And some information search methods influenced their overall satisfaction. Therefore, food-sonics corporations need to try reducing negative images of various advertisements and activating positive aspects of specialized promotion instruments.

One of The standard issue in riding on the wave of the information system(IS) is records of performance, grow unprecedently fast, and has highly uncertain future. Within the framework of IS Evaluation, The main purpose of this study is to suggest performance quality evaluation system as follows, The Integrated Quality Evaluation Model Design(IQEMD) of Information System helps corporations to improve productivity, customer service and corporate competitive power. To respond flexibly this trend, we have to realize that the information system has to keep the most effective optimal information network at the proper time. The existing evaluation method has been concentrated on the evaluation of a degree of the information system maturity focused on static viewpoints. The evaluation of potential factors to affect the future-oriented performance, that can analyze both unit business being able to apply an information system base was used efficiently well and what performance evaluation item was obtained actually, was insufficient relatively. In this paper, An integrated quality evaluation method will analyze a degree of information system maturity in dynamic evaluation viewpoints rather than in static evaluation viewpoints. finally we estimated the relative degree of importance of each determinant using the AHP methodology The validity of the proposed model was also partially proved using two different methods, holistic and historical approach.

정보 통신 산업이 비약적으로 발달하고, 디지털컨버전스(Digital Convergence) 시대가 도래함에 따라, 각 정보주체들의 정보를 자신들의 의도에 따라 유지 관리하고, 보호하는 것은 시대적 요청으로 급부상하였다. 그에 따른 각 분야별 정보보호 산업이 비약적으로 발전하게 되었음은 물론이다. 정보보호 산업 전체의 경쟁력을 제고 하고, 기술발전과 국제경쟁력을 키우기 위해서는 여러 정보보호 기업들을 조직적으로 관리하고, 각 분야별 전문 업체를 유기적으로 결합시키도록 하는 것이 요청되며, 정보보호 지주회사의 설립은 이러한 요구에 부응하는 하나의 제도적 방안이 될 수 있다. 정보보호 지주회사의 설립으로 소기의 목적을 달성하기 위해서는, 정보보호 지주회사에 대한 법적 성격 구명 등 기본 연구가 필요하다. 현재 주도적 정보보호 기업을 대상으로 그 지배구조와 사업범위, 조직 형태를 법적 관점에서 분석하고, 이를 바탕으로 우리 법제도 하에서 정보보호 지주회사의 활용 가능성을 타진해 본다.

This study was intended to help children to cultivate and develop a sound attitude toward food consumption and eating habits through the analysis of food and nutritional information in news articles and advertisements in three major daily children's newspapers in Korea: The Chosen Children's Daily Newspaper, The Hankook Children's Daily Newspaper, and The Donga Children's Daily Newspaper. The monitoring period was for twelve months, January to December 2003. Two hundred seventy-nine articles and three hundred thirty-five advertisements were analyzed. The results were as follows. 'Cooking and health' were the most frequent subject in food and nutrition articles. The articles' contents are evaluated positively in morality and explanation; but negatively in fairness, specialization, and objectiveness. The articles were insufficient in the explanation of professional terms, scientific bases, and practical measures for real life. It therefore seems that they were difficult for children to understand well. The most frequent themes in the advertisements were 'processed fats and sugars' such as chocolate, candies, and cookies. Frequently, they were exaggerated and accompanied by phrases promoting consumption. They did not provide sufficient well-grounded information, and focused too much on events or gifts to instigate consumer sentiment. In conclusion, the most serious problem was that most food and nutrition information in these children's newspapers was lacking in specialization. More specialized and objective information should be provided in order to enhance the educational value of children's newspapers and their utilization in school education programs. Continuous monitoring should be carried out to discover those news articles and advertisements that contain correct food and nutrition information.
