This study examines web query types and topics submitted to Naver during one year period by analyzing query logs and click logs. Query logs capture queries users submitted to the system, and click logs consist of documents users clicked and viewed. This study presents a methodology to classify query types and topics. A method for click log analysis is also suggested. When classified by query types, there are more site search queries than content search queries. Queries about computer/internet. entertainment, shopping. game, education rank hightest. The implications for system designers and web content providers are discussed.

There is little study related to the 3D convergence contents authoring tool for teacher. In this study, we purposed the design of the interactive 3D convergence contents authoring tool for a teacher. To draw the design, firstly, we investigated the authoring environment of teachers and interviewed teachers. Based on this investigations, we proposed the functional requirement and UI/UX(User Interface/User Experience) design of it. And we investigated the level of focusing group satisfication with the UI/UX design. Based on these results, we will implement the authoring tool.

This study explores the empirical impact of parents' concerns and cultural capital on using Internet with elementary school children. Using the representative data from the 2010 korean adolescent panel data, this study found that the degree of parents' concern for their child directly affected to the Internet using behavior. This study showed the following results. The patterns of Internet use depended on their parents' attitude. The time for game decreased according to the increase of the parents' concern, while the time for searching information for learning increased. Cultural capital directly and indirectly affected to the behavior of Internet use. These results implied that children felt less need to use Internet to spend their time since they learned how to spend the time and to make relationships with other children through the cultural experiences.

With the recent development of medical technology, the diagnosis rate of type 1 diabetes is increasing and patients are increasing. However, diabetes education content is not aligned with the interest level of children. As a result of the interviews with experts, It was found that the measures of coping with the change of blood sugar and the behavior therapy require steady and repetitive learning. Therefore, this study proposes Edutainment content which can be repeatedly Learned by 10~11year old children. For effective learning, the contents of the laboratory practice were constructed and the hybrid method was used for the repetitive learning. Usability test showed that this configuration is effective. This study is expected to contribute to the study of diabetic education content that is suitable for the children's level of understanding which will be developed easily in the future.

본 연구는 가상 캐릭터인 3D Pooh 와의 감성 교감이 이루어지는 유아용 감성 교육 게임 개발이 목적이다. Web 카메라를 이용하여 사용자의 위치 정보 및 영역을 검출하고 사용자는 화면에 보이는 가상 공간에 손과 마커를 이용하여 행동을 가하게 된다. 사용자의 행동 입력 방식에 따라 Pooh 의 상태를 나타내는 게이지와 행동의 다양한 변화를 제공하며, 이로써 사용자들이 가상 캐릭터인 3D Pooh 와 인터렉션을 할 수 있도록 제공한다. 기존의 감성 교감 연구 방법 분석 결과 뇌파와 체온 등의 생리신호를 이용한 방법과 사용자의 행동패턴을 분석하는 방법 등이 있으며, 현재는 생리신호를 이용하는 방법이 더 많이 활용되고 있다. 생리신호 측정 시 사용자는 신체에 센서를 착용해야 하므로 착용 부담감과 움직임이 자유롭지 못하다는 단점이 있다. 본 프로그램은 기존 연구의 단점인 센서 착용의 부담감을 줄이고 자유롭고 편리한 인터렉션이 가능하도록 개발하였으며, 직관적인 인터페이스를 기반으로 유아들도 쉽고 편리하게 즐길 수 있도록 구현된 감성 교육 게임이 될 것으로 기대된다. 또한 카메라 이외의 다른 하드웨어 장치 사용을 최소화하여 경제성과 사용 편의성을 동시에 고려한 효율적인 유아용 감성 교육 게임으로 활용될 수 있다.

The purpose of this study is to investigate social relationship and housework implementing of the elderly households in Chungbuk and to provide suggestion s from the perspective for the well-being of the elderly. The data of this study are collected through questionaire and the data of 244 respodents are analyzed using Frequency Contingency analysis one-way ANOVA. The results are as follows: firstly most elderly tend to have a close relationship with their neighbors in their houses. The activity of social relationship is routine behavior and the satisfaction of social relationship with their neighbors is high, The older the age the lower the education level and the poorer in physical health the more frequently they meet their neighbors and friends the more frequently they go to establishments for elderly and tend to play games such as a flower cards game. Secondly the average time implementing housework by elderly women is about 3.63 hours. The attitude toward housework is a l ttle negative. The average housework eqipments owned by them are 4.8 The older the poorer in physical health the lower level of owning housework equipments the shorter is the time implementing housework and the more negative is the attitude toward housework.

Virtual world is persistent 3D(2D) space through computers which supports real-time interaction. Children's virtual worlds are for children below 15. Its educational benefits are: practical experience, cooperation possibility, experience sharing, and optimized environment. Moreover, interesting factors from games can enhance the educational efficiency of virtual worlds. In order to intensify the educational efficiency, goal, motivation, relationship and advice has to be considered as well. Based upon those factors, the result of analysis of current virtual worlds shows that they have clear goal. contextualization of task and appropriate reinforcement. However, for future prosperity, continuous effort for expansion of readiness, social persuasion, scaffolding are needed.

This study intends to analyze the projection factors' difference on each record of women's javelin throwing. For this purpose, the research analyzed the best record and the lowest one of athletes in top 1~7 ranks respectively, who participated in 2009 Daegu Pre-Championship Meeting. For analyze kinematic factors, we analyzed their game photos mainly shot by 3 cameras installed in side places. The used analysis program was Kwon3D 3.1. Analysis variables were the projection velocity, angle, height, trunk lean angle, and supporting leg's knee angle. The results concluded as follows: Different record showed statistically significant differences(p<.05) in terms of horizontal velocity and resultant velocity. There were no statistically significant differences in the variables of projection angle, its height, trunk lean angle and knee angle of support leg. But for the analyzed results to each individual characteristics, the horizontal velocity, projection height, knee angle of support leg and trunk lean angle of release event appeared to have influence on record.

With the rapid evolution of communication technology, it became possible to overcome the spatial and temporal limitations faced by humans to some extent. Furthermore, the quality of personal life was revolutionized with the emergence of the personal communication device commonly known as the smart phone. In terms of defense networks, however, due to restrictions from the military and security perspectives, the use of smart phones has been prohibited and controlled in the army; thus, they are not being used for any defense strategy purposes as yet. Despite the current consideration of smart phones for military communication, due to the difficulties of network configuration and the high cost of the necessary communication devices, the main tools of communication between soldiers are limited to the use of flag, voice or hand signals, which are all very primitive. Although these primitive tools can be very effective in certain cases, they cannot overcome temporal and spatial limitations. Likewise, depending on the level of the communication skills of each individual, communication efficiency can vary significantly. As the term of military service continues to be shortened, however, types of communication of varying efficiency depending on the levels of skills of each individual newly added to the military is not desirable at all. To address this problem, it is essential to prepare an intuitive network configuration that facilitates use by soldiers in a short period of time by easily configuring the strategy network at a low cost while maintaining its security. Therefore, in this article, the author proposes a Zigbee-based local strategic network by using Opnet and performs a simulation accordingly.
