This study reviewed the influence of consumer innovativeness and consumer knowledge on external information search behavior for the purchase of high-tech products. The strategies for offering information effectively for high-tech products may be proposed as follows based on the results of this study. First, the advertisements of high-tech products which are generally encountered need to offer sufficient information about the products in addition to fulfilling the function of persuading consumers. Second, it is necessary to implement an information network so that neutral offerings of information about high-tech products may be made promptly by reliable institutions. Third, information about high-tech products should be offered with easier explanations so that there should be no information-underprivileged class in utilizing the function of high-tech products.

이동로봇에 통신 기술을 결합하여 응용하려는 시도는 Tele-Robotics라는 학문의 한 분야로 이미 국내외적으로 정착되고 있다. 초기에 Tele-Robotics.Tele-Operation 기술은 극한작업을 위해서만 사용되었으나, 최근에는 일상생활과 밀접한 다양한 분야로 그 응용분야를 넓혀가고 있다. 본 논문에서는 대화식 무선통신 기능을 가진 이동로봇을 제작하고 그와 통신할 수 있는 호스트 시스템을 구성하여 이동 로봇의 원격 제어, 원거리에서의 지형 탐색, 데이터 수집 기능 등을 구현함으로써 본격적인 원격 탐색 시스템 구축을 위한 기초 연구를 수행하였다.

This study aimed to measure consumer information competency, which indicates consumers' general ability to search and utilize information. The model of this study was constructed in order to identify how consumer information competency influences the efficiency and the effectiveness of external information search. The model was verified with related prior knowledge as a moderator variable in order to understand holistic consumer information search activity. The result of the study is as follows. First, the concept of consumer information competency was constructed with four sub-abilities: define, search, extract, and synthesis & use. The ability of define was the highest, as opposed to the ability of extract, which was the lowest. Second, consumer information competency was lower for women as well as for low family income. The sub-abilities of search and synthesis & use were lower for aging consumers. Third, consumer information competency has positive effects on information search efficiency and effectiveness. Moreover, the efficiency influences the effectiveness positively. Fourth, prior knowledge moderates the effect of consumer information competency to the efficiency. Only for consumers with high knowledge the efficiency has the effect of mediating between consumer information competency and the effectiveness.

For the development of unmanned autonomous vehicle, it is essential to detect obstacles, especially vehicles, in the forward direction of navigation. In order to reliably exclude regions that do not contain obstacles and save a considerable amount of computational effort, it is often necessary to confine computation only to ROI(region of interest)s. A ROI is usually chosen as the interior region of the lane. We propose a computationally simple and efficient method for the detection of lanes based on Hough transform and quadratic curve fitting. The proposed method first employs Hough transform to get approximate locations of lanes, and then applies quadratic curve fitting to the locations computed by Hough transform. We have experimented the proposed method on real outdoor road scene. Experimental results show that our method gives accurate detection of straight and curve lanes, and is computationally very efficient.

Through a story, the audience moves between fiction and reality. A story is an emotional experience that appeals to human feeling. The rational function of a story is to convey knowledge and information, and its emotional function is to touch the audience. Moreover, these aspects of a story are linked to its language, text, and imagery. This paper focuses on the emotional function of a story. In a experiential story, the audience's emotional response is a result of maximum dramatic communication between them and the characters. Through psychological and mental communion with the characters, the audience becomes immersed in the story when they emotionally identify with the characters, and dramatic communication is achieved. However, dramatic communication is mostly achieved instantaneously. The elements of a film need to be realized to sustain dramatic communication such that the audience continues to be immersed in the story. The audience can identify with the characters who are placed in real-life situations by considering the characters' external and internal aspects. External search pertains to the tangible aspects of the character such as its background, life, and conversation. Through the audience's external search, the characters communicate with the audience. Internal search deals with aspects of the characters' personality such as their self-concept, desires, and internal conflicts. Through internal search, the audience understands the inner side of the characters. In this process, a film director should ensure that the acting depicts the inner side of the characters. In other words, the director should perfectly depict the internal and external elements of a human on screen. Appropriate visualization can lead to dramatic communication with the characters and thereby create the audience's emotional response. Considering these techniques, this paper focuses on the scenes of the film "Poetry" in which dramatic communication with the characters creates the audience's emotional response. Accordingly, the audience plays a role in sustaining dramatic communication for the physical screen time of a film.

본 논문에서는 메쉬 구조의 다중처리시스템을 위한 새로운 할당방법을 제안한다. 이 할당방법은 다른 가용 서브메쉬와 중첩되지 않는 독립 가용 서브메쉬를 유형에 따라 분류하여 유형별 가용 서브메쉬 리스트를 생성한다. 그리고 태스크의 유형에 따라 해당 유형별 가용 서브메쉬 리스트에서 최적할당이 가능한 서브메쉬를 찾음으로써 서브메쉬를 탐색하는데 소요되는 시간을 줄인다. 이 때 서브메쉬를 찾지 못하면 확장지수를 이용하여 더 큰 가용 서브메쉬를 형성한 후 할당함으로써 태스크의 대기 시간을 줄이고, 이 결과로 외적단편화를 줄이는 효과도 얻는다. 또한 할당 해제시 독립 가용 서브메쉬는 다른 가용 서브메쉬의 크기 에 변화를 주지 않기 때문에 그 유형에 따라 유형별 가용 서브메쉬 리스트에 삽입한다. 그럼으로써 할당 해제 후 유형별 가용 서브메쉬 리스트를 재생성하기 위해 전체 메쉬 구조를 탐색 할 필요가 없어진다.

This paper is a qualitative single case study and it was conducted for the purpose to explore change in interactive bibliotherapy experience with a middle-aged widowed spouse. A Middle-aged Widowed Spouse was taken as a research partaker. Through this research, we explored partitively the partaker's experience changes by each session during the commencing of interactive bibliotherapy and the partaker's inner/external experience change after the end of session. The result, interactive bibliotherapy facilitated and expressed the reaction of a partaker by its writing skills and reading materials including partaker's own poems. Furthermore, facilitated emotion from material and self-awareness made a partaker understand and accept itself through therapeutical interaction. In addition, those kind of changes appeared inner/external experience in life, and lasted after the end of the session. In this regard, the inner/external change appeared from a partaker means the effect of bibliotherapy, and we can notice that it is a result that facilitated through truthful reaction of counselor and texts.

The decision tree is a representative algorithm of data mining and used in many domains such as retail target marketing, fraud detection, data reduction, variable screening, category merging, etc. This method is most useful in classification problems, and to make predictions for a target group after dividing it into several small groups. When we create a model of decision tree with a large number of input variables, we suffer difficulties in exploration and analysis of the model because of complex trees. And we can often find some association exist between input variables by external variables despite of no intrinsic association. In this paper, we study on the removal method of unnecessary input variables using multiple external association rules. And then we apply the removal method to actual data for its efficiencies.
