미래의 스마트 유비쿼터스 컴퓨팅 기반 시스템은 사용자들과 상호작용을 통해 적절한 서비스를 제공할 것 이다. 사용자 요구(Needs)에 맞는 서비스를 제공하기 위해서는 기존의 개발자 중심의 개발보다 사용자의 요구를 반영하는 사용자 중심의 시스템 개발이 필요하다. 이를 위해 이전 논문에서는 사용자 행위 분석 기반 요구 추출방법(User Behavior Analysis Based Needs Extraction Method)을 제안하였다[1]. 본 논문에서는 추출된 사용자의 요구사항을 Fillmore의 Case Grammar을 이용하여 객체 추출 및 모델링 방법을 제안한다.

In this study, we propose a virtual community recommendation model based on user behavioral models. It is designed to recommend optimal virtual communities for an active user by applying case-based reasoning (CBR) using behavioral factors suggested in the technology acceptance model (TAM) and its extensions. Also, it is designed to filter its case-base by considering the user's needs type before applying CBR. To test the usefulness of our model, we conduct two-step validation - experimental validation for the collected data, and survey validation for investigating the actual satisfaction level. Experimental results show that our model presents effective recommendation results in an efficient way. In addition, they also show that the information on the user's needs type may generate opportunities for cross-selling other commercial items.

공공도서관 이용자들의 정보요구를 파악하기 위하여 웹사이트에 제시된 요구 내용을 분석하였다. 이용자마당이라고 표시한 메뉴에서 이용자들의 정보요구를 나타내는 사항은 모두 조사하였다. 이 정보요구에는 개별도서관에서 제공하는 정보서비스에 대한 불만사항이나 건의사항으로만 제한되고 있는 약점이 있다. 데이터의 분석은 자료수집, 정보서비스, 대출, 디지털자료실, 열람실, 참고질의, 기타 등으로 구분하여 실행되었다. 이 연구결과는 개별 공공도서관의 정보서비스 개선에 도움이 될 것이며, 새로운 정보서비스를 개설할 때에도 참고가 될 것이다.

대학도서관 이용자의 정보요구를 파악하기 위하여 15개 대학도서관의 웹사이트 게시판에 올라온 이용자의 불만사항, 건의사항, 요구사항을 분석하였다. 정보요구를 희망도서, 대출 및 반납, 정리과정 오류, 디지털자료, 전산시스템, 기타사항 등으로 구분하여 분석하였다. 이 분석결과는 디지털환경에서의 대학도서관 서비스개선에 필요한 기초 자료로 이용할 수 있을 것이다.

Rapid changes to the paradigm of smart media have created a communication environment through merging with various media such as IoT technology, which is internet of things. Among them, user' need for a start home, which is one of people living conditions, has been growing and values of the communication environment in a living space using a smart mirror have been growing. However, studies on figuring out behavior and analyzing needs of family members who actually use the living space are insufficient. This study is to draw the service system of the home smart mirror by analysis of behavior and needs of users of the living space. For a research method for analysis of behavior of family members, I wrote two kinds of user's experience maps, which are frequency of use of a quantitative space of a living space and space's important value scales by persona study and depth interview. Through this, applied spaces of the home smart mirror (living room, bathroom, powder room, dress room, porch, kitchen, room) and the types of user needs (type of providing information, entertainment type, control type, service type) have been drawn and statistical analysis methodology has been utilized for a research of user preferences in regard to correlation between living spaces and types of user needs based on a survey. As a result of analysis of ages and gender, types of user needs by space have been drawn and the service system of the home smart mirror has been drawn. It would be utilized as a basic material for various contents development and design using the smart mirror in the future.

A great deal needs to be learned about why and how users participate and consume information on various online sites. The design of socio-technical systems especially for promoting engagement in terms of maximum user participation is both a theoretical and real-world challenge that researchers strive to understand. At present, most of the research on the motives of Internet video users' behavior focuses on the user's "viewing motivation" and "sharing motivation", and lacks the analysis of the factors affecting users' "subscription motivation". This study will attempt to compensate for this gap. Based on the YouTube platform, we take Chinese video users as the research object and uses the "Censydiam user motivation analysis model" to make assumptions about user subscription motivation from the two levels of social needs and personal needs, using regression analysis. Validate the hypothesis and get the influencing factors that may be available in the user's subscription motivation based on the assumptions. Built on survey data from 215 respondents, the study found that Enjoyment, Vitality, Power, and Conviviality are four factors that influence user motivation.

대학도서관 이용자들은 도서관 홈페이지 게시판을 통하여 도서관에 대한 그들의 요구나 불만사항을 전달하는 것이 일반화 되어있다. 본 연구는 게시판에 나타난 이용자 요구 및 불만사항을 조사, 분석하였다. 조사대상으로는 12개의 국내 대학도서관과 3개의 외국 대학도서관을 선정하였으며 연구의 결과는 이용자 요구사항을 제도적으로 반영할 수 있는 개선책 마련에 도움이 될 것이다.

Recently, Internet is used widely. Many Web sites, however, are not designed based on user's view. So, this research aimed at grasping the user needs and structure of Web site which user used easily. First, to grasp user needs, questionnaires about the motivation, the purpose and the evaluation items of Web page were done. As a result, we found the easiness for the user. Next, we made subjects operated test pages in which the number of classes and the amount of information were changed. We collected the quantitative data of the optimum number of classes, amount of information and retrieval time. As a result, there was a significant difference in each numerical value. The results of this research are available when constructing a web site. so, usability of Web site can be improved by them.

The purpose of information retrieval is to help users solve their problems. To fulfill the purpose the user's problem needs to be focused on. The purpose of this study is to identify components and the structure of the user's problem in an academic research environment. From this study it was found that the scientific problem dealt within an academic environment is complicate and the problem is composed of 8 topical and 4 non-topical components. And they could be organized into a stucture. This study has three implications for user-oriented information retrieval. (1) The components and the structure of the problem need to be the framework for the effective information retrieval process and for the evaluation of information retrieval. (2) The research methodology used in this study can be applied to other information service situations and this will result in greater practical implication of a study for more effective information retrieval. And (3) for more effective user-oriented information retrieval, the user needs to be observed and studied in the actual' situation. This study showed that the complicate problem of the actual user can be studied in a systematic way and this resulted in important implications for information retrieval.

Personalized reminder systems have to identify the user's current needs dynamically and proactively based on the user's current context. However, need identification methodologies and their feasible architectures for personalized reminder systems have so far been rare. Hence, this paper aims to propose a proactive need identification mechanism by applying agent and semantic web technologies and RFID-based context subsystem for a personalized reminder system, which is one of the supporting systems for a robust ubiquitous service support environment. We have created a prototype system, RFID-based NAMA (Need Aware Multi-Agent), to demonstrate the feasibility of the methodology and of the mobile settings framework that we propose in this paper. NAMA considers the context, user profile with preferences, and information about currently available services, to discover the user's current needs and then link the user to a set of services, which are implemented as web services.
