The purpose of this study is to suggest the modeling of ubiquitous environments according to the analysis of user's behaviors focused on the living area within the house. Recently, with appearing 'Ubiquitous environments', the applications of ubiquitous technologies on the our environment adopt a new paradigm. This new paradigm leads to the possibility of creating more intellectual dwelling environment according to user's behaviors. This paper suggests to change our dwelling by considering both engineering technology and the character of dwelling, because the house should provide causes humans with comfortability. Therefore, we need to understand user's behaviors in the dwelling, towards user friendly environment. Also, it very important for us to configure proper sensors and technologies by the priority based on user's behaviors. To sum up, this study is aimed to analyze user's behaviors and then, to suggest the guideline for users offering optimal ubiquitous environments.

Traditionally, the emphasis of the information services had been placed on the information provider's knowledge of information sources or information systems. However, in view of the increasing complexity of the information environment. and changes taking place in information professions the evaluation of the information services has callded for further research in interpersonal communication aspects of the librarian user interface especially that which links to user satisfaction. This experimental study was carried out for the purpose of exploring the implications of nonverbal behaviors in measuring user satisfaction in the light of the fact that the meaning of nonverbal clues includes more than verbal communication especially in dealing with variable barriers even though they operate at low levels of awareness. In this sense, among the wide range of nonverbal communication areas in particular kinesics, artifacts and the proximics were examined to suggest alternative model which can be applied effectively in our specific set of information work environment. Two major university libraries and two research libraries in Korea were chosen and visited for the anlysis and per each refernce/information interview the librarian's nonverbal behaviors were checked on the observer's checklist and the qustionnaires completed by the user at a time. On the basis of these data firstly, the relation of user satisfaction concerned with the librarian's nonverbal communication to user satisfaction with information services was analyzed and the possible communication barriers were investigated. In addition, the effect of training the information librarian with positive nonverbal communication skills on the user's satisfaction was analyzed in a SAS computer program in the area of kinesics. On the other hand, the effect of other nonverbal behaviors such as proximics and artifacts known very important clues to improving a complex human interaction was discussed along with their experimental results. In conclusion, it was found that most of users were not sensitive to the importance of nonverbal behaviors exposed by the information librarian, but it was proved that the ultimate user satisfaction and the satisfaction of the librarian's nonverbal behaviors are correlated positively, Moreover, nonverbal behaviors displayed by the trained librarian toward the user had a considerable effect on the user's evalution of information services compared with those by the untrained. These findings imply that in order to control the librarian's nonverbal behaviors and to help the user overcome his barriers the information librarian as a specialist needs to assure and modify willilingly his communication behavior. Without making effective use of such nonverbal communication, information librarian could not expect to meet the user's information needs either. However, when these positive nonverbal behaviors are applied it would be highly desirable to be aware of cultural and contextual differences. With regard to increasing information services success the applicable nonverbal communication model for library management and education can be suggested as below.

The thermomechanical behaviors of the shape memory alloy were conducted through the finite element analysis of ABAQUS with UMAT user subroutine. The unified thermomechanical constitutive equation suggested by Lagoudas was adapted into the UMAT user subroutine to investigate the characteristics of the shape memory alloy. The three cases were solved to investigate the thermomechanical characteristics of the shape memory alloy. The material properties for the analysis were obtained by DSC and DMA techniques. According to the results, the thermomechanical characteristics, such as a shape memory effect and a pseudoelastic effect, could be obtained through the finite element analysis and the analysis results were revealed to agree well with the experimental results. Therefore, the finite element analysis using UMAT user subroutine is one of prominent analysis techniques to investigate the thermomechnical behaviors of the shape memory alloy quantitatively.

Microblog services are such new communication channels with some considerable potential to improve information sharing. The idea of sharing short messages using multiple access points seems to be appealing to people worldwide. Through the lens of flow and social identity, we explored factors that influence information sharing behaviors in microblog services. With an empirical study, we examined enjoyment and concentration(flow) and self-presentation(social identity) in microblog services like twitter can contribute to the user behaviors. Our aim was to gain insight into ways of creating an environment that facilitating voluntary sharing of information. Our findings suggested that enjoyment, concentration, and selfpresentation were crucial determinants of information sharing behaviors in microblog services. This study has important implications for academic researchers and practitioners who seek to understand why microblog service users share their information with other members in microblog services.

So far, the behaviors of Web users have been predicted or analyzed mostly by their demographic characteristics or by considering in which context they gain access to that. But now there is a question about whether those characteristics are the only factors to trigger their use of Web. If the answer is not affirmative, what types of additional factors could cause such an action and how they characterize it should be discussed. User profile information has been considered one of the crucial elements to define user characteristics in user-centered UI design sector, and in order to apply it to UI design, it's needed to meditate on the above-mentioned questions. In this study, it's first attempted to have a good understanding of the users of different media and to review existing user classification methods. Next, user classification variables and relevant scales were prepared to sort out users according to their type of using Web, and case study was conducted to identify the behavioral characteristics of users and classify them according to their behavioral features. Finally, the user profile features of individual user groups were figured out based on data that were gathered by making an experiment, and data mapping was fulfilled between the behavioral characteristics and user profile characteristics to find out what types of behaviors were caused by the characteristics of user profile. As a result, it's found that user characteristics could have an impact on not only their general information and relevant contexts but their attitude of using different media and personality type. There were some problems with the experimental design, but more accurate information on the relationship of user behaviors to user profile characteristics will be obtained if those problems are eliminated. As user behaviors could be predicted only by user profile characteristics, user classification is expected to make a contribution to enhancing the efficiency of UI design.

According to the Statistics Korea in 2017, the 10 leading causes of death contain a cardiac disorder disease, self-injury. In terms of these diseases, urgent assistance is highly required when people do not move for certain period of time. We propose an unusual event detection algorithm to identify abnormal user behaviors using dust, vision and activity sensors in their houses. Vision sensors can detect personalized activity behaviors within the CCTV range in the house in their lives. The pattern algorithm using the dust sensors classifies user movements or dust-generated daily behaviors in indoor areas. The accelerometer sensor in the smartphone is suitable to identify activity behaviors of the mobile users. We evaluated the proposed pattern algorithms and the fusion method in the scenarios.

The purpose of this study was to determine the differences in internet use motivations and problem behaviors among vocational high school students according to internet addiction and family system type. Five hundred vocational high school students from Daegu took part in the survey. The questionnaire survey consisted of an internet addiction self-assessment scale, a family system type scale, an internet use motivation scale, and a problem behavior scale. The data was analysed using MANOVA and Cronbach a, and the $Scheff\acute{e}$ test was used for post-hoc analysis. The major findings of this study were as follows: First, the study found significant differences in adolescent internet use motivation according to internet addiction. Adolescents in the high dangerous user group showed higher communicative, experiential, and addictive motivations than adolescents in potentially dangerous and normal user groups. Also, there were no significant differences in informative motivation according to internet addiction. Regardless of internet addiction, adolescents tend to use the internet to search for information and to solve problems. Second, there were significant differences in adolescents' problem behaviors according to internet addiction. More specifically, adolescents who were in the high dangerous user group displayed more problem behaviors toward their body, family, school, and society than adolescents in the potentially dangerous and the normal user groups. Third, an adolescent's family system type significantly influenced his/her internet use motivation. Adolescents from an extreme family showed higher communicative and addictive motivations than adolescents from middle and balanced families. Fourth, there were significant differences in the problem behaviors of adolescents according to family system types. Adolescents from an extreme family showed more problem behaviors toward their body, family, school, and society than adolescents from middle and balanced families.

As a neighboring country belonged to the same cultural sphere with the Northeast Asia, China is recently emerging as a center of the world's economy. The social transformations caused by the rapid economic growth are bringing changes in the Chinese housing culture and thus, it is considered that the identification of a user's need concerning a new housing space and social and cultural understanding on China are necessary. Accordingly, this research intended to conduct the basic research on the Chinese housing space design by observing the small apartment users in Shanghai area in terms of not only the tangible element of the residential space type but also the intangible elements such as lifestyle, values, behaviors, etc. The research range was limited to the kitchen area at the center of a house as a place where the exchanges among the family members are most frequently occur, and the research was carried out in the following methods. First, the effective user research method for the analysis of the Chinese small apartment kitchen users was studied through the literature investigation. Second, the 6 families of a research target were selected focused on the small apartments in Shanghai, China and the user research was performed using three methods of User observation, Video ethnography, and Contextual inquiry. Third, the research results were analyzed focused on the flow of human traffic in the kitchen area and user's behaviors. What were identified as a result take account of the human traffic movements in the kitchen areas around the sink-counter-cook top, cooking behaviors and meal areas outside of the kitchen. Through this, the need for the effective organization of the sink-counter-cook top, arrangement of meal area, and placement of storage by section for the kitchen space of China were drawn based on the understanding of the cooking process, and it was identified that such results require comprehensive understanding of Chinese housing culture.
