This study aims to suggest improved design for both non-smokers and smokers to minimize inconvenience of smoke, at the same time, allow smoking in comfortable environment. The study was researched in three categories: First, consciousness research regarding smoking booth, second, preference research regarding product design, and third, research on emotional words about smoking booth by emotion evaluation. The result of design preference research was, first of all, smoking booth for smokers should be designed in both notable and familiar shape rather than stiff and rough shape. Second, color for the booth should apply warm colors such as white, pastel, and bright tone rather than prime colors. Third, the internal circulation filter in smoking booth should be managed thoroughly. In addition, extra seats and ventilation design is necessary to prevent passive smoking. The result of emotion evaluation was that people recognized certain words in four aspects. Each image word for factor 1 was "functional emotion', factor 2 was "psychological emotion", factor 3 as "color emotion", and factor 4 as "shape emotion". User-centered service design is necessary for both smokers and non-smokers, to minimize the damage by smoke and to spend time for short break.

The relationship between chemical structures and biological activities is researched briskly in the area of 'Medicinal Chemistry' At the base of these structure-based drug design tries, medicinal chemists search the existing drugs of similar chemical structure to target drug for the development of a new drug. Therefore, it is such necessary that an automatic system selects drug files that have a set of chemical moieties matching a user-defined query moiety. Substructure searching is the process of identifying a set of chemical moieties that match a specific query moiety. Testing for substructure searching was developed in the late 1950s. In graph theoretical terms, this problem corresponds to determining which graphs in a set are subgraph isomorphic to a specified query moiety. Testing for subgraph isomorphism has been proved, in the general case, to be an NP- complete problem. For the purpose of overcoming this difficulty, there were computational approaches. On the 1990s, a US patent has been granted on an atom-centered indexing scheme, used by the RS3 system; this has the virtue that the indexes generated can be searched by direct text comparison. This system is commercially used(http://www.acelrys.com/rs3). We define the RS3 system's drawback and present a new indexing scheme. The RS3 system treats substructure searching with substring matching by means of expressing chemical structure aspredefined strings. However, it has insufficient 'rerall' and 'precision‘ because it is impossible to index structures uniquely for same atom and same bond. To resolve this problem, we make the minimum-cost- spanning tree for one centered atom and describe a structure with paths per levels. Expressing 2D chemical structure into 1D a string has limit. Therefore, we break 2D chemical structure into 1D structure fragments. We present in this paper a new index technique to improve recall and precision surprisingly.

This research examined the difference in cognitive load and the virtual presence depending on auditory feedback and task difficulty in haptic-based dental simulation. In the field of dental education, practice-centered training using handpiece has been crucial because a practitioner's psychomotor experience has a significant impact on the mastery of treatment skills. For the novice, it is necessary to reduce errors in dental treatment to enhancing skill acquisition in the haptic practice. In the training process, the force-feedback is crucial to elaborate subtle movement to guide what to do and how it should be hard or soft. However, It is not easy to add force-feedback to generate kinetic experience training. As an alternative method, we examined that auditory feedback can help learners' skill training. In this study, we analyzed how the presence/absence of auditory feedback at the different levels of task difficulty impacts learners' psychological demand and virtual presence in the virtual reality simulation. For this study, 29 dental college students participated in a dental simulation. The participants were grouped into two conditions that are with and without auditory feedback. Additionally, two consecutive tooth preparation tasks with different levels of difficulty were used in the simulation. The auditory feedback condition gives alarms to a learner when he treats a non-targeted tooth with a virtual handpiece. The user's cognitive load and virtual presence were measured to examine the effects of auditory feedback. The results revealed that the main effect was found in cognitive loads. Also, a significant interaction effect was shown in the virtual presence. We discussed the effective design methods for the virtual reality-based dental simulation through the result of this study.

In this paper, we analyzed the units related to robot education in the Practical Arts textbooks according to the 2015 revised curriculum. As a result, all textbooks had a common system of introduction, development, and organization, and all of them showed a similar flow. Learning objectives were presented in all textbooks, but no affective goals were presented except cognitive and functional goals. The contents of robot learning suggest the meaning and type of robots, the structure and sensors of robots, and the activities of making robots, but the contents of robot ethics, the production and activities of various robot works, and the use of robots in the problem solving process are not presented. The assembly robot and the infrared sensor are used in common, and it consists of presenting robot production and control training materials in experience activities and arranging units through evaluation, and the A, C, and F textbooks also provide the unit auxiliary data. In the future, it will be necessary to include the contents of robot ethics education centered on the design/manufacturer and user-oriented robot ethics such as the recognition of the limits of robots, the principles of using robots correctly, safety education, personal information and privacy protection.

The implication of space in school libraries more important than the other types of libraries because their main user is students who are affected by service environment. Let me consider the reality of our circumstance, the space is not enough in the school library, Therefore, it is essential to utilize of library space effectively. So, this study intends to suggest effective organization model of school library space, through introduced by the notion of information commons. The results show that they are integrated within school library, which, in addition to other functions, may include recreation center, and interactive community, circulation space, administrative offices and so on and suggest the library space design and management need to reflect the flexibility and inter-activeness of the space. Also, in order to acquiring human-centered aspect and openness, school library appropriate space planning for present needs and future expansion is imperative within school community.

컴퓨터 네트워크의 발달로 인터넷이 실생활이 되면서, 온라인에서 인스턴트 메신저를 이용한 커뮤니케이션 방식이 확대되고 있다. 이러한 메신저에서는 이모티콘 및 플래시콘 혹은 윙크 등 과 같은 다양한 방식을 통해 감정을 표현할 수 있도록 제안하고 있다. 하지만, 아직까지 온라인의 감정표현은 흥미위주이며, 오프라인의 다양한 감정표현에 비해서 제한적이다 따라서 오프라인에서의 다양한 사용자 감정표현을 온라인에서 표현해 줄 수 있는 새로운 형태의 감성 커뮤니케이션 방법이 필요하다. 본 연구에서는 온라인 인스턴트 메신저의 사용행태 이해를 통해서 사용자들의 요구사항을 파악하고 이를 통해 제안할 수 있는 커뮤니케이션 방법을 모색하고자 한다. 실생활에서 사용자의 감정표현 방법을 바탕으로 온라인 메신저에 적용하여 새로운 감성 커뮤니케이션 방법을 제안하는 연구로, 감정어휘와 표현방법의 사용자 조사를 통해 감정표현 방법에 대한 컨셉을 제안하였다. 우선 메신저 사용 행태와 요구사항 도출을 위한 사용자 FGI를 진행하였다. 사용자 FGI로 얻어진 사용자들의 메신저 사용행태를 통해, 텍스트와 모션을 활용하는 '텍스트콘'을 컨셉 아이디어로 도출하였다. 아이디어에 적용하기 위해 모션을 감정으로 인해 파생되는 행동과 체감각 요소로 구분하였다. 구체적인 표현방법 및 적용 요소를 추출하기 위한 방법으로 온라인 설문조사를 실시하였으며 감정어휘와 표현방법(행동, 체감각)을 추출하였다. 추출된 내용은 '사용자 참여 관찰' 기법을 활용하여, 사용어휘와 행동을 정리하고 구제화하여 그 결과를 '텍스트콘'에 적용하였다. 본 연구는 사용자들이 메신저를 이용한 감정표현에 있어 텍스트를 선호하고 텍스트에 대한 요구사형에 있음을 확인하였으며, 감정표현 컨셉 아이디어 '텍스트콘'을 도출하였다. '사용자 참여 관찰' 기법을 활용하여 기존의 이모티콘으로 대표되는 그래픽 아이콘 중심의 사용자 감정표현 방법을 보조해줄 수 있는 방법으로 실생활에서 사용자가 표현하고 받아들이는 신체언와 행동을 적용하였다는 것에 그 의의가 있다. 또한, 감정에 의한 생리적 반응 요소를 외적인 반응과 내적인 반응으로 구분하여, '체감각'이라고 하는 내적반응을 중심표현방법으로 삼아, 기존과는 다른 시각으로 접근할 수 있었다.
