In ubiquitous computing, shared environments are required to adapt to people intelligently. Based on information about user preferences, the shared environments should be adjusted so that all users in a group are satisfied as possible. Although many group recommender systems have been proposed to obtain this purpose, they only consider average and misery. However, a broad range of philosophical approaches suggest that high inequality reduces social agreeability, and consequently causes users' dissatisfactions. In this paper, we propose social welfare functions, which consider inequalities in users' preferences, as alternative aggregation functions to achieve a social agreeability. Using an example in a previous work[7], we demonstrate the effectiveness of proposed welfare functions as socially agreeable aggregate functions in group recommender systems.

The purpose of this study was to present a developmental direction of the early childhood social education in kindergarten by investigating the mother's perceptions using the focus group interview. Mothers who have 4~5 year old children were selected for 3 focus group interviews. The following results were obtained: 1) The mothers recognized early childhood social education as an essential step before entering elementary school. 2) The mothers were found to have recognized that the cultivation of the various social situations of the children in kindergarten would be a very important task of the kindergarten, because kindergarten is a place for children to be introduced to social experiences for the first time in their lives. 3) Most of the mothers have the perception that early childhood social education showed positive effects on the development of their children. This perception was based on the evaluation of the social educational effect of kindergarten compared to that of elementary school.

This study examines the roles of user resistance and social influences on the acceptance and continuous usage of smartphones at different stages of adoption. The respondents were classified into three groups according to their innovation adoption stage : non-user group, the potential user group and the trial user group. Theories relevant to user resistance, social influences including normative social influences and informational social influences, as well as user adoption and continuance behavior were reviewed and integrated into our research model. In order to verify the proposed structured equation model, we conducted an online survey by targeting mobile phone users and collected data to be analyzed through a partial least squares (PLS) test. This study tested whether there exists differences in the effects of user resistance and different types of social influence on user's adoption or continuance intetion among these three groups. The results showed that user resistance exists in all adopter groups and that it has significant negative influences on intention to use a smartphone. The findings also revealed that user resistance can be enhanced or resolved by two types of social influence; informational social influence resolves user resistance regardless of the adopter category, while normative social influence enhances the user resistance of potential users. Furthermore, the findings show that social influence regardless of the type positively affects user intention. Several theoretic and practical implications pertaining to the results are discussed.

This study aims to analyze differences in the social presence of instructor by instructor's social intervention, the effects of the social presence of instructor on learning satisfaction, and learner characteristics related to the social presence of instructor. Data including subjects' demographic information, interactions, social presence of instructor, social presence of the course, and learning satisfaction were collected from 119 adult learners in an online university in Korea. The main findings of this study are as follows. First, the social presence of instructor was higher in the higher-aged group or active group on intranet message board than the lower-aged group or inactive group on the board. Second, instructor's social intervention increased the level of perceived social presence of instructor. However, the active group on the board has shown the highest level of perceived social presence of instructor, without instructor's social intervention. Third, there was a high correlation between instructor's social intervention and the social presence of instructor, while the variables affecting learning satisfaction were the social presence of instructor and social presence of the course. From the results of this study, it is suggested that instructors' social interventions be provided systematically for those who are not active in social interaction to enhance their learning satisfaction.

Methods: This study was designed using the nonequivalent control group pre-posttest design. Sixty students were assigned either to the experimental group (30 students) or control group (30 students). Data were analyzed with $x^2-test$ and t-test using SPSS/WIN 20.0 program. Results: The experimental group showed significant higher scores for social problem-solving ability (t=2.12, p=.038) and self-leadership (t=2.91, p=.007) compared to the control group 5 weeks after the program finished was supported by significant differences in the scores between the two groups. Conclusion: These findings showed that the Health Education program has a significant effect on improving social problem-solving ability and self-leadership in nursing college students and the program can be used as a tool to promote the social problem-solving ability and self-leadership of Health college students.

The purpose of this study was to investigate the effect of social interaction on metacognition, learning motive and academic achievement in elementary science learning. The science lessons emphasizing social interactions that is applied to this study was comprised of 5 stages, 'introduction', 'inquiry activity', 'small group emergent activity', 'large group emergent activity', 'conclusion and assessment'. The results of this study were as follows: First, applying the learning model emphasizing social interaction to the experimental group led to a significant difference between the result of the pre- and post-test, regarding metacognition, especifically those of declarative knowledge. And meaningful difference was drawn from the results of all elements in the lower category of regulation of cognition between the experimental and comparison group. Second, a significant difference was found between the pre- and post-test regarding learning motive, especially those of attention, relation, and self-confidence. Third, after applying the learning model emphasizing social interaction to the science classes of the experimental group, students' academic achievement improved significantly in the post-test, compared to the results of pre-test.

Responsiveness and initiative between infant and mother from toy centered play situation at 6, 7 months of age and infant's social communication skills at 12 months were studied in a sample of 62 infant-mother pairs. Through the video analysis, infants were grouped into simple react group, cooperated group, and active initiative group. In the between groups, we analyzed whether mother's initiative act styles and response styles were different, and whether their social communication skills were different when they tested at 12 months. The results showed that mother's initiative styles were not different but mother's response styles were significantly different with infant groups. Further result showed that cooperated group gained higher score than active initiative group in the total score of Eary Social Communication Skills scales at 12 months of age. The results suggested that mother's responsive behaviors were more important than initiative behaviors for the infant's positive interaction, and the difference of these behaviors would lead to a gap of early social communication abilities.
