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.

User review sites are spaces where users can freely post and share their opinions, which are trusted by many people and directly influence sales. In addition, they overcome the limitations arising from existing requirements collection and are able to gather the needs of large numbers of different people at a low cost. Therefore, such sites are attracting attention as new spaces for understanding user needs. In a previous study, a user review analysis was attempted using 5W and 1H, and we inferred that a sentence containing "when" has special information based on the user experience. In addition, the requirements of the derivative activities in a user review can identify more user needs than the general requirements of derivative activities. In this paper, we propose a systematic method of deriving "when" sentences contain meaningful information from user reviews and converting them into use cases, which is one of the requirements of a specification method. This method converts unstructured data into structured data such that it can be included as the user requirements during software development from user comments expressed in natural language. This method will reduce project failures and increase the likelihood of success by enabling an efficient collection and analysis of user needs from valuable user reviews.

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.

주거환경에서의 사용자 요구사항은 매우 다양하고 복잡한 연계관계를 갖고 있다. 근 미래의 u-Home시스템은 기존 사용자들의 요구 수용뿐만 아니라 U-home관련 신기술의 요구사항도 접목해야 한다. 본 연구에서는 이러한 사용자의 요구사항을 보다 효율적으로 시스템에 반영하기위해 사용자의 행위 데이터를 기반으로 요구유형을 분류하고 시스템 개발에 활용할 수 있도록 사용자 행위분석모형UBAF(User Behavior Analysis Framework)을 제안 하고자한다. UBAF는 SE에서의 시스템 모델링 방법과 HCI 관점의 사용자 모델링 방법을 접목한 개발 프레임워크이다. 이를 통해 u-Home에서 정형화된 방법으로 사용자들의 핵심행위를 시스템 개발에 적용할 수 있었다. 적용사례로 u-Home의 실내 온도 조절 시나리오를 분석하여 시스템 모델링과 사용자 행위를 지식화 하였다.

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.

Purpose: This study aimed to design user interfaces of a mobile application for managing pressure injury patients in a long-term care hospital based on the user's needs. Methods: To reflect users' needs in the mobile application, the user interfaces in this study were designed in five steps: brainstorming and mind mapping, persona and scenario, needs list and priority, a draft version of flow chart and user interfaces and expert review. These steps were conducted with a step nurse at a long-term care hospital, a professor who majored in nursing informatics, a professor who had lots of research experiences about pressure injury and a wound ostomy continence nurse. Results: Two personas, scenarios and needs' lists were derived. Listed Needs included the followings; Accurate staging of pressure injury; Appropriate management by staging; Acquisition of professional knowledge about pressure injury; Acquisition of easy pressure injury information through text, picture and video; and Sharing pressure injury information in unit. The structure, menus and features of the pressure injury mobile application were visualized with user flow based on two personas' scenarios and needs' lists. Conclusion: Our study suggests and visualizes the key features of the 'Pressure Injury Guide', a pressure injury management mobile application for nurses in a long-term care hospital, which can be utilized by nurses, application developers, and related researchers.

There are two broad classes of user studies, in terms of their purposes or a n.0, pplications. One class might be termed basic studies, in which the purpose is to create or obtain knowledge regarding information needs and uses with no particular a n.0, pplication. The second type of study might be termed a n.0, pplied. The aim of second type is preparing standards to evaluate and improve existing information systems or to design new systems. The trends of user study tend toward basic research from a n.0, pplied ones. Furthermore, not only the broad-based studies change with special setting up and subdivided studies, but also the scopes of user study vary social scientist, human scientist, and even common users from limited natural scientists and technologists earlier. The aims of this paper is to summarize continuously pointed problems of user studies and to survey the state of the arts by reviewing the trends of user studies. The major problems of user studies are terminology, conceptualization, and methodology. These terms are essential to this study, and very important to decide the research fields and to select a method of survey, respectively. And in order to predict the user needs, studies of 'information needs' are inevitable instead those of 'information demands' which principally studied till nowadays. On the other hand, to reduce the problems of user studies, it is needed more qualitative studies ever than before and cooperation with other areas, for example, behavioral 'science, psychology, communication science and so forth.

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.
