In this paper, we develop an AI-based recommendation system that matches the specifications of smartphones from company 'S'. The system aims to simplify the complex decision-making process of consumers and guide them to choose the smartphone that best suits their daily needs. The recommendation system analyzes five specifications of smartphones (price, battery capacity, weight, camera quality, capacity) to help users make informed decisions without searching for extensive information. This approach not only saves time but also improves user satisfaction by ensuring that the selected smartphone closely matches the user's lifestyle and needs. The system utilizes unsupervised learning, i.e. clustering (K-MEANS, DBSCAN, Hierarchical Clustering), and provides personalized recommendations by evaluating them with silhouette scores, ensuring accurate and reliable grouping of similar smartphone models. By leveraging advanced data analysis techniques, the system can identify subtle patterns and preferences that might not be immediately apparent to consumers, enhancing the overall user experience. The ultimate goal of this AI recommendation system is to simplify the smartphone selection process, making it more accessible and user-friendly for all consumers. This paper discusses the data collection, preprocessing, development, implementation, and potential impact of the system using Pandas, crawling, scikit-learn, etc., and highlights the benefits of helping consumers explore the various options available and confidently choose the smartphone that best suits their daily lives.

최근 사용자 중심의 스마트시티 서비스에 관한 관심이 높아지고 있다. 본 연구는 사용자 중심의 스마트시티 서비스를 계획하 기 위한 사전 연구로 사용자의 니즈를 조사하였다. 본 연구는 스마트시티 서비스에 대한 니즈를 도출하기 위해 GIS 기반 위치분석데이터와 비디오 에스노그래피 방법론을 활용하고자 한다. 본 연구는 스마트시티 테스트베드로 선정된 대전 도안지구의 현장조사를 통해 사용자의 집객도가 높은 지역을 세부조사대상지로 선정하고, 도로교통공단의 교통사고분석시스템(TAAS : Traffic Accidents Analysis System)의 위치분석데이터를 이용하여 주변 보행환경을 함께 조사하였다. 또한 비디오 에스노그래피의 고정카메라기법을 통해 사용자의 행위 유형과 변화를 관찰하였다. 추출된 영상데이터를 통해 사용자의 활동을 11개의 세분화 된 유형으로 분류하고, 관찰되는 문제점 및 특이사항을 분석하였다. 본 연구를 통해 조사된 사용자 행위특성은 향후 사용자 중심 스마트시티 서비스를 제안할 수 있는 근거를 마련한다는 점에 의의가 있다.

The purpose of this study is to provide a cultural and artistic content guide service that can provide customized guides according to the disability status of the disabled who consume cultural and artistic contents. It is designed to provide a more individualized service through user input of disability information including the type and degree of disability of the disabled, the type of cultural and artistic content desired by the disabled, and information on the cultural and artistic level of the disabled. In addition, it is not limited by time and place, and it has the distinction of providing appreciation of cultural and artistic contents and commentary information of the corresponding cultural and artistic contents in various ways on the application. In particular, to provide cultural and artistic contents differently by identifying the type or degree of disability of the user, or to provide cultural and artistic contents with different expertise in consideration of the user's cultural level and taste, and to improve the cultural level. The most special feature is that it provides recommended content in consideration of the difficulty of art content. User analysis was conducted through in-depth interviews and persona techniques. As a result of the analysis, the needs for the enjoyment of culture and arts are also increasing among the disabled, while the services that reflect those needs are very insufficient. Therefore, all interviewees stated that they are willing to actively utilize these services if they are released. In the future, it is necessary to increase the accessibility of the disabled to culture and arts by developing various services using new ICT technologies.

스마트TV는 2000년대 초 등장한 스마트폰과 더불어 새로운 산업시장을 형성하고 있다. 스마트폰의 등장과 IT기술의 발전으로 사용자들은 더욱 만족도가 높은 애플리케이션을 추구한다. 스마트폰은 다양한 애플리케이션으로 사용자들의 요구를 충족하고 있지만 스마트TV는 사용자의 요구를 반영한 애플리케이션의 부재로 발전의 저하를 초래하고 있다. 스마트TV가 대중화 되고, 사용자의 요구를 충족시키기 위해서는 고사양의 애플리케이션이 아닌 스마트TV가 스마트하다고 느낄 수 있는 접근이 필요하다. 그러므로 본 논문에서는 최신 IT기술을 이용하여 스마트TV 애플리케이션을 제안한다. 이는 스마트TV, 스마트폰, 헬스자전거를 하나의 시스템으로 연동하여 사용자에게 실제 거리를 주행하는 것과 같은 느낌을 제공한다. 이를 위하여 Web OS, HTML5 웹 소켓, 안드로이드 기술을 이용한다.

Relevance has a long history of scholarly investigation and discussion in information science. One of its notable concepts is that of 'user-based' relevance. The purpose of this study is to examine how users construct their perspective on the concept of relevance; to analyze what the constituent elements (facets) of relevance are, in terms of core-periphery status; and to compare the difference of constructions of two groups of users (information users vs. information professionals) as applied with a social representations theory perspective. Data were collected from 244 information users and 123 information professionals through use of a free word association method. Three methods were employed to analyze data: (1) content analysis was used to elicit 26 categories (facets) of the concept of relevance; (2) structural analysis of social representations was used to determine the core-periphery status of those facets in terms of coreness, sum of similarity, and weighted frequency; and, (3) maximum tree analysis was used to present and compare the differences between the two groups. Elicited categories in this study overlap with the ones from previous relevance studies, while the findings of a core-periphery analysis show that Topicality, User-needs, Reliability/Credibility, and Importance are configured as core concepts for the information user group, while Topicality, User-needs, Reliability/Credibility, and Currency are core concepts for the information professional group. Differences between the social representations of relevance revealed that Topicality was similar to User-needs and to Importance. Author is closely related to Title while Reliability/Credibility is linked with Currency. Easiness/Clarity is similar to Accuracy. Overall, information users and professionals function with a similar social collective of shared meanings for the concept of relevance. The overall findings identify the core and periphery concepts of relevance and their relationships in terms of coreness, similarity, and weighted frequency.

In this paper we will discuss a general idea about an information system which provides information a user really needs in user's authentication. We will discuss how RFID could be applied for this kind of system especially from the standpoint of using RFID as a way to collect information of personal belongings. Also we will discuss security issues of using RFID as a component of the proposed system because while RFID could provide usefulness, it could also be very dangerous for revealing private information without user's awareness.

To be a good architecture, resident' needs should be defined as possible as definitely. A Multi-family housing is not easy to define of resident' needs, because the user is ambiguous and the needs is multi aspects. Byker housing project have a good approach to define ambiguous and many aspects of residence' need. In this view points, Byker redvelopment project show the process of resident' participation as a new customers, and design process architect with people, in spite of the early 1970s' project in terms of the user participations. This approach of residence participation is a good lesson how to communicate with recidence, how to identify the need, and its design is satisfied in the residence. And its project are discussed with residence how to manage of rehabilitation.
