This study is to analyze the differences of consumer preferences between the terrestrial DMB and satellite DMB in various segment groups by using survey data. We categorized the consumers by the DMB preference patterns into four groups, i.e., non users group, terrestrial only users group, satellite only users group, dual users group. And then we analyzed the differences among these four segment groups in demographic characteristics, behavior patterns on telecommunication and broadcasting services, life-style, attitudes to DMB services.

We conducted a user-centered usability testing on the Android-based Mobile Augmentative Alternative Communication(AAC) Software. In this paper, we examined functionality, satisfaction, and ease of information searching for a specific function using a task scenario, and we investigated appropriateness of development purposes, contents, instructional strategies, usability, functions of management mode, and user interface of the mobile AAC to the communication needs of children who are nonverbal. We also examined user requirements, preference, satisfaction, and other personal opinions for the mobile AAC using an open feedback. In addition, we investigated users' preference for the size of mobile devices using 4.3", 5.0", and 7.0" mobile devices.

전자상거래에서 사용되고 있는 추천시스템은 사용자들의 프로파일과 이들의 정보를 바탕으로 사용자가 선호할 만한 아이템을 추천한다. 추천시스템에서 널리 사용되고 있는 협력적 필터링 방식은 사용자들 사이의 선호도 평가치를 비교하여 유사 사용자를 선택하고, 아이템에 대한 유사 사용자의 선호도 평가치를 기반으로 하여 추천하고자 하는 아이템에 대한 사용자의 선호도를 예측하는 것이다. 하지만 사용자의 선호도가 적은 데이터로 인한 희소성 문제는 추천시스템의 성능을 저해하는 요인으로 작용하고 있다. 이러한 희소성의 문제는 선호도 평가 자료에 나타난 아이템들의 총수에 비하여 사용자가 선호한 아이템의 수가 아주 적기 때문에 발생하며, 새로운 사용자의 경우에는 아이템에 대한 선호도 평가치가 없어 유사 사용자를 선택할 수가 없어 나타나며 심한 경우에는 아이템을 전혀 추천할 수 없게 된다. 이리할 추천 시스템의 희소성문제를 해결차기 위한 방법은 희소성이 높은 데이터들에 대한 희소성을 감소시키는 것이다. 따라서 본 논문에서는 아이템에 대한 희소성을 조사하여 협력적 필터링에서 희소성 아이템이 MAE에 미치는 영향을 분석하였다. 그리고 희소성 문제를 완화하여 예측 정확도를 높이기 위한 방법으로 선호도가 적은 아이템에 대해 희소성을 최소화하는 연구와 이에 따라 희소성과 MAE의 값을 개선하는 방법을 제안한다.

본 연구는 한국인들이 선호하는 열차용 시트 디자인에 대한 감성특성을 파악하고 이를 실제 디자인으로 구체화하고자 실시되었다. 시트 디자인의 감성평가를 위해 형용사들을 추출하였고, 이를 이용하여 한국인들이 기대하는 열차용 시트 디자인의 감성특성을 조사하였다. 여기서 추출된 감성특성을 실제 디자인으로 보다 쉽고 구체화시키기 위하여, 특징적인 시트 디자인들을 시각적인 그림으로 제시하고, 각각에 대한 감성특성 및 선호도 평가를 실시하였다. 이러한 결과들을 종합하여 선호되는 시트 디자인의 감성특성과 이러한 감성특성과 관련을 가지는 실제 디자인 특징에 대하여 분석하였다. 이를 토대로 새로운 시트들을 디자인하여 2차 디자인 평가를 실시하였고, 가장 선호되었던 디자인을 최종 디자인 대안으로 결정하였다.

This study analyzes the key factors of 3D spatial information in accordance with the establishment of aerial and ground equipment fusion, and the quality improvement solutions are delivered from the preference survey. Furthermore, it investigates the factors affecting the quality of the individual technical elements through the establishment of three-dimensional spatial information. It is for identifying the priority which needs to be improved, and this data will be used to identify the evaluation for factors, the technology development and its application. For this purpose, the presence or absence of equality is judged by the quantitative techniques through the preference survey of the gap between the experts of spatial information and survey and the general users who have experiences on 3D spatial information.

While there is no apparent gender difference on the number of game players and playing time in market survey especially if the age group is under 30, there still exists a strong gender stereotype on female characters with sexual objectification especially in team based battle games. Furthermore, there seldom exists any research on female gamers in this genre. In this paper, we investigate the preference of female characters and reasons of their choice among female gamers with Overwatch and Cypers which are recognized as having enough female players. In Overwatch with 231 responses, subjects prefer 'girl-crush' characters such as non-sexual Ana who age is in 60s. However, in Cypers that does not have female warrior character, subjects' preference is more affected by appearance but those characters with less functional ability are not frequently used in playing. Such practical avatar choice is often discovered among male players thus there is no gender difference in this case.
