Ethnography, a major research method in Anthropology, has been recently applied in human-centered design research. Since ethnography has empirical, naturalistic, holistic and eclectic characteristics, it is needed a guideline to apply ethnography into design research in accordance with a characteristic of project. Design project in which ethnography is applied can be categorized by two criteria; degree of newness of project goal(existing user-potential user) and limitedness of worksite(site-oriented-work-oriented). Among work-site activities, technology in use, and user group culture, it should be decided which content to content to focus more than others and thus what kinds of research techniques to apply in the ethnographic research.Case study was to design an interior of a Korean express train. This project is site-oriented and has an existing-potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity potential users. Therefore, video ethnography was effectively applied to obtain chronological data of activity flow, and participant observation was applied to obtain statistical data of synchronous activities. Case study shows a concrete process example of how to apply ethnography into design research.

Engineering design involves the specification of many variables that define a product, how it is made, and how it behaves applied to computer, communication and control fields. Before some variables can be determined, other variables must first be known or assumed. This fact implies a precedence order of the variables, and of the tasks of determining these variables consequently. Moreover, design of complex systems may involve a large number of design activities. In this paper, the activity-activity incidence matrix is considered as a representation of design activity analysis which mainly focuses on the precedence constraint with an object of doing IDEF3 in process-centered view. In order to analyze the activity-activity incidence matrix, a heuristic algorithm is proposed, which transforms an activity-activity, parameter-formula, and parameter-parameter incidence matrix into a lower triangular form. The analysis of the structured matrices can not only significantly reduce the overall project complexity by reorganizing few critical tasks in practice, but also aims at obtaining shorter times considering the solution structure by exploring concurrency.

People with visual impairments are difficult to go to education facility by themselves, because of their limited visual ability, orientation, and usability field, so they prefer dormitories. Those dormitories playa role in living space, education, communication and culture function. Therefore those facilities planned more user centered design, since they are influenced by user actability and their values. User centered designs that match between the user and space are understood as well as their characteristics and behavior. Especially for understanding their activity, observation is conducted about their behavior in dormitories. Thus the purpose of this study is suggested to be a basic source that planning about residential facility for people with visual impairments through interview and observation investigation by analysis that they resident in space motion and performance.

사용자 중심 디자인(User-Centered Design)은 주어진 환경(Context)에서의 사용자 행동(Activity)을 모델링 하여 사용자가 기능적, 논리적으로 주어진 작업(Task)을 수행해 낼 수 있는 상품의 디자인을 가능케 하는데 크게 기여한 바 있다. 그러나 사용자 중심 디자인은 사용하기 편하고 유용한 측면을 디자인하는 데는 큰 기여를 했지만, 소비자의 감성 및 문화를 고려한 상품 디자인을 개발하는 측면에서는 아직 성공적인 사례를 제시하지 못했다는 비난을 받고 있는 것도 사실이다. 이는 사용자 중심 디자인이 사용자의 요구사항 (기능적인 요구 사항)에만 치중하는 접근법이기 때문으로, 사용 상황이 중요한 공공 시설물이나 기업 소프트웨어의 개발에는 적합하지만 소비자를 직접 대상으로 하는 디지털 컨텐트 및 디지털 가전의 디자인을 위해서는 부족한 면이 없지 않아 있는 것으로 발표되고 있다. Jordan은 이러한 문제법의 해결안을 제시하면서, 사용자 요구사항의 다차원적(개인적, 사회적, 인지적, 물리적) 접근법을 제안하였고, 그것을 Pleasure-based Approach라고 명명하였다. Jordan도 사용자 조사의 중요성은 부각하였지만, 사용자 조사의 결과를 상품 개발에 접목시키기 위한 방안은 제시하고 있지 못했다. 본 논문에서는 Kano의 상품 속성 모형을 도입하여 사용자 조사 방법과 상품 요소 도출과의 연결고리를 발견하고자 하였다. Kano 모델에서는 상품 요소를 크게 기본요소, 퍼포먼스요소, 엑셀런트 요소로 나누어 설명하고 있다. 퍼포먼스 요소는 설문조사와 같이 직접적으로 고객으로부터 얻을 수 있는 요소로 설명하고 있다. 그러나 기본요소 및 엑셀런트 요소는 직접적인 사용자 조사를 통해서 얻을 수 있는 요소가 아니라 고 주장하고 있고, 이런 요소들을 도출하기 위하여 경쟁상품분석, 참여적 소비자 조사 등과 같은 방법이 도입되어야 한다. 고 말하고 있다. 이에 본 연구에서는 '13-18 청소년용 온라인 커뮤니티 컨텐트 개발 프로젝트' 를 중심으로 엑셀런트 요소 및 퍼포먼스 요소를 도출하기 위한 참석 관찰의 프레임 워크를 제시하고, 그 결과를 기능적 요소, 감성적 요소로 정리하여 상품개발에 활용하도록 하였다. 본 연구의 의의는 상품개발에 사용자 조사의 필요성 및 활용도를 실질적인 프로젝트를 통하여 시도해 보았다는 데 있다고 할 수 있겠다.

Conventional vector quantization (VQ) codebook design methods have several drawbacks such as edge degradation and high computational complexity. In this paper, we first made activity coordinates from the horizonatal and the vertical activity of the input block. Then it is mapped on the 2-dimensional interconnected codebook, and the codebook is designed using kohonen self-organizing map (KSFM) learning algorithm after the search of a codevector that has the minumum distance from the input vector in a small window, centered by the mapped point. As the serch area is restricted within the window, the computational amount is reduced compared with usual VQ. From the resutls of computer simulation, proposed method shows a better perfomance, in the view point of edge reconstruction and PSNR, than previous codebook training methods. And we also obtained a higher PSNR than that of classified vector quantization (CVQ).

Purpose - The purpose of this study is to conduct a monitoring study on the learning process of e-learning contents. This study has two research objectives. First, by conducting monitoring research on the learning process, we aim to explore the implications for content development that reflects future student needs. Second, we want to collect empirical basic data on the estimation of appropriate amount of learning. Research design, data, and methodology - This study is a case study of learner's learning process in e-learning. After completion of the study, an in-depth interview was made after conducting a test to measure the total amount of cognitive load and the level of engagement that occurred during the learning process. The tool used to measure cognitive load is NASA-TLX, a subjective cognitive load measurement method. In the monitoring process, we observe external phenomena such as page movement and mouse movement path, and identify cognitive activities such as Think-Aloud technique. Results - In the total of three research subjects, the two courses showed excess learning time compared to the learning time, and one course showed less learning time than the learning time. This gives the following implications for content development. First, it is necessary to consider the importance of selecting the target and contents level according to the level of the subject. Second, it is necessary to design the learner participation activity that meets the learning goal level and to calculate the appropriate time accordingly. Third, it is necessary to design appropriate learning support strategy according to the learning task. This should be considered in designing lessons. Fourth, it is necessary to revitalize contents design centered on learning activities such as simulation. Conclusions - The implications of the examination system are as follows. First, it can be confirmed that there is difficulty in calculating the amount of learning centered on learning time and securing objective objectivity. Second, it can be seen that there are various variables affecting the actual learning time in addition to the content amount. Third, there is a need for reviewing the system of examination of learning amount centered on 'learning time'.

As the design of the day focuses more on human-centered design, this shift creates value for society and also fulfills on a sense of social responsibility. In the area of fashion, the design activity is used as a type of fashion design to realize the social value of design in a changed society; this concept was defined as Fashion Design Activism. The objective of this study is to empirically research design activity as a practical value of the day when the social contributions of fashion design are rising in the overall society through the research on the practice of Fashion Design Activity which is adapting to changes in the fashion design paradigm. Regarding the study method, the literature research and case study were combined. We examined the meaning of social design by reviewing the literature related to this social paradigm, and we analyzed cases in which the effects of fashion design on society were realized through practical activities. Also, we defined the role of fashion design based on an analysis of design types based on previous research. This study divided the roles of fashion design in a pattern based on the social roles that design inhabited, in terms of how 'fashion design fulfilled on social responsibility', 'anthropocentric fashion design putting emphasis on users', and 'fashion design aiming for eco-efficient changes'. This study aimed to seek measures to develop fashion design that could promote changes focusing on society, humans, and the environment.
