  • There have been researches on game continuance intention based on consumer behaviour theory of management science. Such macro access of computer game analysis might be insufficient to draw valuable results due to complex subsystem structure of recent computer games. In this paper, we choose 'Blade and Soul' game that was first published in 2012 and has been within top 20 MMORPG in Korea but known as a 'long time users' only game'among game players recently. Three user groups - long loyalty, concentrated, casual - are classified based on their play history and play time per day of Blade and Soul. The first survey with 222 subjects revealed that the real strength of the game was not the combat - Dungeon, Arena, Battleground competition - but very cohesive game community Blade and Soul has. Thus, we conduct another survey on the game community issues among 148 long time users (over 3 years playing history) and analyze their traits and behaviour patterns.

  • As the interest and use of computer have been increased among elderly users according to the entry to the aging society, the issue of universal design for computer usability was brought forward. Especially, it is widely recognized that universal UI(User Interlace) design on MS windows is important. The objective of this study is to conceptualize Universal GUI design on MS windows which can be used more easily and intuitively by novice users such as elderly and housewives. Especially, the solution for Universal GUI design on MS windows was developed by reflecting elderly users' needs because elderly users is the group with more difficulties than other user groups in learning and using MS windows. First, elderly user's needs was collected by participant observation as a teaching assistant in computer dass for elderly people for 4 weeks. Secondly, the experimental test and in-depth interview was implemented to find difficulties factors and needs in addition to participant observation. Based on the findings, the new GUI design solution was suggested. The design solution consists of ideas in several categories such as setting default, simplification of function for easy conceptual model making, customization of function and working environment, and intuitive GUI in interaction process. The new MS windows GUI design can be accessed by novice mode when user login in window XP. This study has the significance in finding elderly users detailed needs through in-depth and long term participant observation. However, the usability of the suggested prototype needs to be verified to various user groups besides elderly users in the future.

  • An expert system is developed which can design the power transmission involute cylindrical gears on the basis of strength and durability. Bending strength, surface durability, scoring, and wear probability are considered as the basis. The basic components of the expert system are knowledge base, inference engine, and working memory. The knowledges in knowledge base are classified hierarchically into the knowledges used in selection of gear type, selection of materials, and determination of K factor and are represented by rules. In the inference engine two inference methods are implemented with the depth first search method. For-ward chaining method is introduced in the selection of gear type and materials and in the determination of K factor. Backward chaining method is introduced in the detailed design of module and face width in accordance with the validation of strength. And inference efficiency is achieved by constructing the part needing a lot of numerical calculations in strength estimation separately from inference mechanism. The working memory is established to save the results during inference temporarily. In addition, design database of past design results is built for consultation during design and knowledge acquisition facility, explanation facility, and user interface are included for the usefulness of user. This expert system is written with the PROLOG programming language and the FORTRAN language in numerical calculation part which interfaced with PROLOG and can also be executed on IBM-PC compatible computer operated by MS-DOS alone.

  • This study is designed to expand 'Q-Methodology' into the global marketing realm in attempt to find out how Canadian consumers will perceive Korean food. The ultimate aim of this thesis is to lay a basic foundation to globalize Korean food and heighten the potential and quality of Korean food. Korean food, well-known as slow diet, jumps on the bandwagon of the Korean Wave and spreads at a rapid pace. At this point, most Korean food becomes widespread under the influence of the boom of not just the Korean Wave but also the growing desire for health food. Hence, it is the most important to analyze consumers' types in order to learn how each individual nation perceives Korean Food. This can be used as the basic research and study to enhance the national competitiveness of Korean food. Q-methodology is adopted in this study to reveal the critical dimensions and characteristics of the target market and/or consumers for Korean Food using the Canadian respondents' subjective attributes. Three categories (pragmatic trend type, traditional culture seeking type, a beginner type) of Canadian consumer behavior regarding Korean Food are found and suggested in this study. The objective attributes of Korean food are not considered here, but the Canadian consumers' subjective behavioral attributes are.

  • The eyes, the saying goes, are the windows of the soul. It's the first thing you notice about a person. Therefore, many people want to possess beautiful eyelids. Surgical formation of a palpebral fold and sulcus divides the lid into two well-defined segments (palpebral and pretarsal), producing the double eyelid desired by many Oriental women as well as an increasing number of man recently. Upper lid blepharoplasty is the Oriental eye is one of the variations of standard upper lid blepharoplasty. In Oriental double eyelid surgery, there have been two approaches to form a superior palpebral fold: the buried suture(nonincision) method and the full external incision method. Conventionally, the nonincision technique has been shown to produce little postoperative edema. However, the probability of the fold disappearing is high, and this technique cannot be performed in patients with fatty eyelids. Conversely, the incision technique has contrary characteristics. Recently, partial incision(or semi-open) technique which is combination of mentioned methods is used, this technique is removal of pretarsal tissue, muscle, and/or orbital fat around 2 or 3 incision site to facilitate tarsus-dermal adhesion. Our method is on the basis of this technique, furthermore, compared with conventional semi-open method, Y(Yang's) needle assisted double eyelid operation is more easy, convenient, saving-time method and provide satisfactory results.

  • Learning at the elbow of scientist is a well-known educational approach to improve students' understanding of science and scientific practice. This study, in the perspective of legitimate peripheral participation in a community of practice, explores how students' scientific practice and perception could be shifted through R&E program with the development of participation. Data from participant observation for 18 months and in-depth interviews were analyzed based on constant comparative method to extract common characteristics of students' participation and major shifts in their scientific practices and perceptions. Students' development of participation was categorized into three stages: legitimate, peripheral, and full participation. In the stage of peripheral participation, students perceived themselves as mere students and showed passive engagement. They just followed the directions of researchers and didn't know what they should be doing. But through continuous participation, students showed enhanced engagement like voluntary article reading, role assignments, and establishing norms in a community of practice with the reference of scientists'. In this stage of transitional participation, students also showed a deepened perception on everyday life of scientist and the community of scientist. And finally in the stage of full participation, students showed responsibility and ownership on research and continuous efforts to refine their research. They recognized themselves as beginning scientists. With these findings, this paper highlighted the dynamic processes of students' development of scientific practices and identity through R&E participation. It also suggests implications for research programs for education, especially for students who have already articulated a science-related career but still have only foggy notions about science.

  • 실내의 조명은 자연채광방식과 인공조명으로 나누어지는데 자연형 채광방식에서도 측창채광과 천창채광, 정 측창채광 그리고 반사 채광방식이 있다. 측창채광은 벽면에 대하여 일반적으로 연직인 창에 의한 채광을 말한다. 측창채광의 방향에 따라 실내조도는 영향을 많이 받는다. 따라서 본 연구는 측창채광의 동서남북의 방향에 따라 봄, 여름, 가을, 겨울의 계절에 따라 아침, 점심, 저녁시간대에 따라 변화되는 실내조도를 알아보았다. 실험방법은, 조명시뮬레이션 프로그램인 Lightscape V3.2를 사용하여 교실공간의 치수와 작업면의 높이를 가로 5.8[m], 세로 10.8[m], 높이 3[m], 작업면의 높이 0.75[m]로 정하였고, 각 시설물의 반사율[p]은 벽 80%, 창문 12%, 출입문 13%, 바닥 20%, 천장 85%로 지정하였으며 창문의 투과율은 88%로 설정하였다. 본 연구에서 측정하고자 하는 변수 값은 계절은 여름을 6월20일, 겨울은 1월20일 기준으로 하고 시간대는 09시, 13시, 18시로 하였으며 창측방위는 동, 서, 남, 북으로 정하였으며 계절과 시간은 가장 차이가 많이 나는 값을 선택하였다. 결론으로 창이 남쪽일 때 평균조도가 9,100[lx]로 가장 높았고, 시간별로는 점심에 19,590[lx]로 조도가 가장 높은 것을 알 수 있었고 조도 균제도는 창이 동쪽일 때 겨울에 가장 높았다. 창이 북쪽일 때는 여름이 겨울보다 평균조도가 약간 높았고, 시간별로는 아침에 조도가 약간 높은 것을 알 수 있었고 전체적으로 북쪽 창에서 실내조도가 현저하게 떨어지는 것을 알 수 있었다. 이와 같은 결과로 측창의 브라인드를 현재 사용하고 있는 수직 브라인드 대신에 수평 브라인드를 사용하여 주광의 범위를 넓게 조절하여 사용하게 하고, 점등제어를 현재 측창면과 수직으로 되어있는 배열을 수평으로 한다면 자연채광의 효과를 배가 할 수 있으리라고 사료된다. 미백 전, 미백후, 재광화 후 미세경도 변화 양상이 미백을 하지 않은 대조군과 차이를 보이지 않았으며 (p > 0.05) 미백 전과 미백 후의 미세경도의 차이 미백후와 재광화 후의 미세경도의 차이도 유의할 만한 차이가 없었다 (p > 0.05). 따라서 시중에 판매되고 있는 whitening strip과 미백 젤은 14일 동안의 통상적인 미백과정 동안 법랑질의 미세경도에 영향을 미치지 않는 것으로 사료된다.able pitch와 helical angle보다는 근본적으로 radial land가 screw-in effect의 예방에 더 큰 역할을 하는 것으로 추정될 수 있다 따라서 NiTi file의 사용 경험이 없는 초심자의 경우 근단부 폭경의 유지능력이 좋은 ProFile$^{(R)}$의 사용이 추천된다.)되었다.였으나 강남콩군 외에는 단백질의 소화 흡수율 및 효율은 크게 향상되지 않아 단백질의 소화 흡수율을 떨어뜨리는 요인에 관한 연구가 집중적 으로 이루어져야 하리라고 생각된다.면 바로 위 지점의 풍속을 측정하였다. 각 Seeding 물질에 대해 팬을 켜지 않았을 때, 즉 바람의 영향이 없을 때 측정한 표면유속을 바람의 세기가 변한 경우의 기준 표면유속으로 이용하였다. 본 연구의 결과 비중이 0.01 내외인 Ecofoam과 white polystyrene에 비해 비중이 0.92인 black polypropylene은 대부분이 물속에 잠겨 있어 흐름과 거의 일치하여 움직임을 알 수 있었다. 또한 흐름의 평균유속이 0.165 m/s의 저유속에서 바람이 tracers에 미치는 영향이 평균유속 0.558m/s인 경우보다 커서, 바람의 세기의 증가에 따라 표면유속 측정값이 급속히 감소되었다. 흐름의 평균유속이 큰 경우에는 바람이 tracer에 마치는 영향이 현격히 줄어듬을 보이고 있다. 결론적으로 유속이 증가함에 따라 바람의 영향은 감소하나, 바

  • In this paper, we propose a design and implementation method of speed quiz content that can be driven by a social robot capable of interacting with humans, and a method of developing an intelligent module necessary for implementation. In addition, we propose a method of implementing speed quiz content through the process of constructing a map by arranging and connecting intelligent module blocks. Recently, software education has become mandatory and interest in programming is increasing. However, programming is difficult for students without basic knowledge of programming languages to directly access, and interest in block-type programming platforms suitable for beginners is growing. The block-type programming platform used in this paper is a platform that supports immediate and intuitive programming by supporting interactions between humans and robots. In this paper, the intelligent module implemented for the speed quiz content was used by blocking it within a block-type programming platform. In order to implement the scenario of the speed quiz content proposed in this paper, we implement a total of three image-based artificial intelligence modules. In addition to the intelligent module, various functional blocks were placed to implement the speed quiz content. In this paper, we propose a method of designing a speed quiz content scenario and a method of implementing an intelligent module for speed quiz content.
