This paper examines the trends of recently developed human-care robots and social interaction technologies. As one of the solutions to the problems of an aging society, human-care robots have gained considerable attention from the public and the market. However, commercialized human-care robots do not meet user expectations for the role as companions. Current robot services based on short-term interaction and fragmentary pieces of intelligence have encountered difficulty in eliciting natural communication with humans. This results in the failure of human-robot social bonding. Social interaction is being actively investigated as a technique for improving robots' natural communication skills. Robots can form a natural bond with humans through social interaction, which consequently increases their effectiveness. In this paper, we introduce recent human-care robot-related issues and subsequently describe technical challenges and implications for the success of human-care robots. In addition, we review recent trends on social interaction technologies and the datasets required.

The order of Rhododendro-Quercetalia mongolicae representing temperate oak forests in Korea was characterized in terms of presence of taxa of different rank. 140 releves were analysed for percentage contribution of each species, genera and families in syntaxa under consideration as well as extracton of diagnostic genera and families for syntaxa by an ordination technique. The Rhododendro-Quercetalia is characterized by high diversity of tree and shrub species contributing 40% of the total floristic composition as well as by a high contribution of the genus Rhododendron and the absence of the genus Fagus, characteristic of the QuercoFagetea sensu lato. The character families for the Rhododendron and Quercus include Liliaceae and Compositae, whereas Acer, Carex, Viola, Rhododendron and Quercus are the most common among genera. Rhododendron and Quercus are regarded as the transgressive cheractergenera, whereas the families of Pinaceae and Ericaceae are considered companions (in sense of the terminology of the Braun-Blanquet syntaxonomy) for the order. Family appeared to be an inadequate rank for diagnoses of alliances and suballiances. On the other hand, genus was found to be the most effective rank in differentiating the alliances and suballiances. The Lindero-Quercenion shares the same character-genera with the order Rhododendro-Quercetalia. Character genera of the suballiances Callicarpo-quercenion are Carpinus, Styrax, Smilax and Callicarpa, and those of the Pino-Quercion list Euonymus, Saussurea and Tilia.

The purpose of this study Is to identify factors for library space programs through user needs assessments in order to apply a library construction. Research method used was a questionnaire and subjects were residents and library users lived in Yongin where a new library was constructing. The results show that library use behavior, age, and user companions are identified as factors to influence to both functional space ratio and functional space arrangement. Heading in libraries is major activity and many subjects went to library with family so that family space is needed. Space for variable ages, also, is needed because of different needs based upon ages.

The aim of this study is to analyze the factors affecting rural tourists' expenditure. This study used the data from the fact-finding survey on rural tourism, and analyzed 4,223 cases who had experienced rural tourism for one year in 2018. The linear multiple regression analysis were used to identify factors affecting rural tourists' expenditure. The result indicate that the factors influencing the rural tourists' total expenditure were age, monthly income, number of accompany, length of stay, accommodation type(pension), accommodation type(friend's house/relatives'house), accommodation type(camping), distance to the destination, accompany(family/relatives), accompany(solo traveler), occupation(white color), motivation(daily escape and rest), motivation(new experience). The result indicate that the higher the age, the higher the average monthly income of the household, the fewer companions, the longer the length of stay higher the expenditure. As for the accommodation, the pension, motel/inn, hotel/condominium, and recreational forest higher probability of expenditure, while, friend/relative's house or camping higher the probability of less expenditure. The longer the distance to the destination, the solo traveler higher the probability of expenditure in rural tourism.

Restaurants have two strategic levers for revenue management: duration control and demand-based pricing. Reducing dining times, especially during peak periods, can add considerable revenue for restaurants. Managing meal duration, however, can be far more complex than manipulating the price. This paper examines dining duration expectations for restaurants types(Family, Korean, Quick service restaurant), customers characteristics(gender, age, occupation, meal period, visiting frequency, dining occasion, dining companions) using an a adaptation of a price sensitivity measurement tool, naming it 'Time Sensitivity measurement tool' or TSM. The TSM is then used to derive the optimal time points, and the range of acceptable times. The results demonstrate that there is a relatively wide spread of acceptable dining duration times in family restaurant. Furthermore, the optimal time points was shorter than the mean expected dining times, which suggests that many restaurants may be able to shorten dining duration without compromising customer satisfaction. The paper explores whether demographic and dining variables have an impact on time preferences, and finds whether gender, age, meal periods, visiting frequency, and dining companion effects are significant. Specifically, women in their thirties tended to prefer a significantly longer dining times for dinner.

Purpose: The purpose of this study was to identify the experiences of Team-Spirit training in new nurses. Method: Data was collected through open-ended and self-reported questionnaires which were received from 47 new nurses who had finished team-spirit training for 2 days. The content analysis method was used to derive the core-category, categories and concepts of Team-Spirit training for new nurses. Result: The care category identified in new nurses trained in Team-Spirit was upgrade myself and our team. The following 4 categories also emerged; companion, interdependency, importance of community, and future growth of myself and our community. The derived 12 subcategories were intimacy, importance of companions, binding, partaking in difficulties, empowerment, observing rules, cooperation, consensus, self-pledge as a subordinator, motivating vision formation, developing professionalism, contribution and devotion. The 34 concepts were derived from the new nurses' statements. Conclusion: These results imply that Team-Spirit Training for nurses could contribute to companionship, interdependency, importance of community, and future growth of oneself and the hospital team.

We present the results of simultaneous observations of SiO v=1, 2, J=1-0, $^{29}SiO$ v=0, J=1-0, and $H_2O$ $6_{16}-5_{23}$ maser lines performed with the KVN Yonsei 21 m radio telescope from 2009 Nov. to 2010 Jan (ApJ, 719, 126, 2010). We searched for these masers in 47 symbiotic stars and detected maser emission from 21 stars, giving the first time detection from 19 stars. Both SiO and $H_2O$ masers were detected from seven stars of which six stars are D-type symbiotic and one is an S-type star, WRAY 15-1470. In the SiO maser emission, the $^{28}SiO$ v=1 maser was detected from 10 stars, while the v=2 maser detected from 15 stars. In particular, the $^{28}SiO$ v=2 maser emission without the v=1 maser detection was detected from nine stars with its detection rate of 60 %, which is much higher than that of isolated Miras/red giants. The $^{29}SiO$ v=0 maser emission was also detected from two stars, H 2-38 and BF Cyg, together with the $^{28}SiO$ v=2 maser. We conclude that these different observational results between isolated Miras/red giants and symbiotic stars may be related with the presence of hot companions in a symbiotic binary system.

With the development of information technologies and the wide spread of smart devices, the number of users of social network services has increased exponentially. Studies that identify user preferences and recommend similar users in these social network services have been actively done. In this paper, we propose a new scheme to recommend social network friends with similar preferences through the moving pattern analysis of mobile users. The proposed scheme removes the meaningless trajectories via companions, short time trajectories, and repeated trajectories to determine the correct user preference. The proposed scheme calculates user similarity using the meaningful trajectories and recommends users with similar preferences as friends. It is shown through performance evaluation that the proposed scheme outperforms the existing schemes.

The purpose of this study was to investigate the differences in adolescents' conspicuous consumption, and their attitude toward and purchasing behaviors for the imported luxuries and the famous brand clothing. A questionnaire survey was conducted to 570 high school students in Seoul; 538 were used for final data analysis. Factor analysis, cluster analysis, $\chi$$^2$-analysis, one-way ANOVA, Duncan's Multiple Range test were used for the statistical analyses. In terms of conspicuous consumption, three factors were formulated: brand and fashion orientation, others orientations, and prize and import orientation. Based on the factor scores, three clusters were identified: the inconspicuous, the others-oriented conspicuous, and the brand-oriented conspicuous. Regarding attitudes toward the products, significant differences were found in all attitudes. The brand-oriented conspicuous showed more favorable attitude toward the products than the other groups. Significant differences were also found in purchasing behaviors except the companions for shopping and purchase time. The brand-oriented conspicuous tended to purchase more, spend more money, prefer department stores, consider brand name and customer service as the most important criteria, and use impersonal informations sources when shopping the products. The other-oriented conspicuous tended to buy bogus products the most, use personal information and consider price and others' perception as important criteria. The inconspicuous were less likely to buy and spend money for the products.

This qualitative study delves into consumers' meanings, perceptions, and behaviors toward the anthropomorphism of fashion goods based on personal experiences. Previous studies focused on consumer responses to the marketer-driven anthropomorphism of products, messages, and brands; however, the present study examines consumers' spontaneous anthropomorphism focusing on personal meanings as a possessor and meanings in their social relationships. A qualitative methodology is adopted that involves in-depth interviews with eleven males and females in their 20s and 30s. Participants stated that were engaged in the anthropomorphic practice of fashion goods on a daily basis. Data analysis was based on grounded theory. Findings on consumer-driven anthropomorphism are discussed at personal and interpersonal levels. At the personal level, anthropomorphic objects are their companions that are often called "baby." Interestingly, anthropomorphism reduces the stigmas of materialism from the participants' side. At the interpersonal level, anthropomorphic practice is a ritual of sharing a common interest and assuring intimacy. Implications and suggestions for future research are also discussed.
