The purpose of this study is to suggest fundamental data for design and planning of university dormitory through the survey of facility condition and resident's satisfaction. The scope of this research is limited to the period from late 1980's to early 2000's. The University Dormitories in Jeollanam-do and Jeollabuk-do are selected as subject. The result of this study is as follow. 1) Even though dormitory's total area is increased than the past, user's satisfaction is still in low level. It's necessary for user to fit a space to life pattern and the difference of human. 2) As a result of comparing of the sexual difference, most men are more active than women in using facility and practice 3) Not only a part of facility but also a part of operation is important element in satisfaction.

Fuzzy Neural Network (FNN) is a compulsory element in a voice-controlled machine due to its inherent capability of interpreting imprecise natural language commands. To control such a machine, user's perception of imprecise words is very important because the words' meaning is highly subjective. This paper presents a voice based controller centered on an adaptable FNN to capture the user's perception of imprecise words. Conversational interface of the machine facilitates the learning through interaction. The system consists of a dialog manager (DM), the conversational interface, a Knowledge base, which absorbs user's perception and acts as a replica of human understanding of imprecise words,...

A computer program, named NEO-PCBRG, for the analysis and design of prestressed con-crete(PSC) bridges was developed using the finite element method. NEO-PCBRG can predict the response of PSC bridges throughout the various stages of construction and service. NEO-PCBRG has both pre- and post-processing capabilities. Pre-processing refers to all the neces- sary steps required to prepare a virtual prototype, more commonly termed a varied model for analysis. Post-processing here stands for the step in which the results from the analysis are reviewed and interpreted. In order to allow for the easy and convenient execution of the entire procedure, NEO-PCBRG was developed using computer graphics in the Visual Basic pro- gramming language. In conclusion, this study presents a new software architecture for analy-sis using the user-oriented design technique.

Since 1980, rapid social and economic development due to increased plant construction has led to a plant dormitory in a short period. In recent years, by the advent of the durability of dormitory remodeling is a critical need. However, user requirements due to the lack of owner's budget do not reflected. As a result, users have complained about the scope of construction, and construction stakeholder in accordance with the budget efficiency of the complaints have decreased. In this study the remodeling requirements in the planning stages is proposed for the remodeling process. In addition work type and element can select a range of construction worksheet are proposal.

In this paper, we propose the ergonomic design method in shape design applicable for Advanced Urban Transit System. Human's sensitivity and User Interface of rolling stock investigated ergonomic studies of several type. The sensibility engineering design made approach of user center design in rolling stocks design. Therefore, we have application to properly of ergonomic design element in rolling stock design. we expert visual design and user interface help greatly in excellent rolling stock design.

With the deployment of web-based educational game over the internet, the user's registration becomes a critical element. The user is authenticated by the system using username, password, and unique code. However, it cannot be handled properly because the data is transmitted through insecure channel on the network. Hence, security requirement is needed to avoid identity leakage from malicious user. In this paper, we propose a secure communication approach using SSL protocol for an online game. We also describe the security requirements for our approach. In future work, we intend to configure and implement the SSL protocol by enabling HTTPS in web-based online game.

With the expansion of metaverse content and hardware platforms, various interactions in the virtual world have been built, raising expectations for an increase in immersion which is a major element of the metaverse. However, among hardware platforms that increase virtual immersion elements, the typical HMD platform can be a barrier to new user inflows due to its high cost. Thus, this paper focused on improving virtual-to-real interactions by extracting motion data using relatively inexpensive webcam equipment in PC environments, utilizing Unity game engines, Photon unity network, multi-platform implementations, and Barracuda neural network inference libraries.

사용자 중심의 디자인 패러다임 변화와 사용자 경험 디자인의 부상으로 특정 공간에서의 제품과 서비스에 대한 사용자 경험의 중요성도 증대되었다. 또한 IoT서비스의 등장과 함께 미래 업무환경의 새로운 변화가 예상된다. 본 연구는 미래 업무공간의 컨텍스트를 고려하여 새로운 사용자 경험 디자인을 제안하는 것을 목적으로 한다. 우선 IoT의 개념과 본질에 대한 고찰을 통해 미래 업무환경에 영향을 줄 수 있는 다양한 요소들을 정의하고 각 요소들의 관계를 파악하였다. 다음으로 현재 업무환경에서의 사용자리서치를 통해 다양한 형태의 업무환경에서 사용자의 행태에 영향을 미치는 컨텍스트를 파악하고, 이를 통해 미래 업무환경에서의 새로운 사용자 경험의 가능성을 보여줄 수 있는 인사이트(insight)를 도출하였다. 그리고 위의 분석과 인사이트를 바탕으로 새로운 미래의 업무환경에 대한 다양한 컨텍스트모델을 구성하고, 그에 따른 UX모델링을 통해 구체적인 UX시나리오와 대안을 제시하였다. 본 연구는 UX디자인의 관점을 디바이스 중심에서 공간과 컨텍스트 중심으로 확장시킴으로써, UX디자인 연구의 다양성에 기여할 것이며 공간디자인 분야와 서비스디자인 분야와의 협력적 연구 및 IoT서비스 관련분야와의 학제적 연구에 기여할 것이다.

The finite element method is one of the most widely used method of structural analysis that has wide applications in diverse fields of engineering and science. The method has been proven effective and reliable in many practical problems. One of the reasons for the methods' popularity is its ease of use, but still the user has to input the finite element mesh which affects the accuracy of the results. The knowledge required to form an effective mesh for a given problem is somewhat complex and for sometime there has been research effort to automate the generation of the mesh and this is called the adaptive mesh generation scheme. A good adaptive mesh scheme seemed to require an accurate assessment of error and generally this requires some additional computation. This paper looks into the possibility of generating adaptive meshes based on representative strain values in each finite element method. The proposed adaptive scheme does not require additional computations other that looking up the data values already computed as finite element analysis results and simple manipulations of these data. Two plane stress problems, a plate with a hole and a deep beam with a concentrated load at the end are considered to show the progress of the improved generation of adaptive meshes using the scheme.
