  • The graph-based tag recommendation algorithm FolkRank can effectively utilize the relationships between three entities, namely users, items and tags, and achieve better tag recommendation performance. However, FolkRank does not consider the internal relationships of user-user, item-item and tag-tag. This leads to the failure of FolkRank to effectively map the tagging behavior which contains user neighbors and item neighbors to a tripartite graph. For item-item relationships, we can dig out items that are very similar to the target item, even though the target item may not have a strong connection to these similar items in the user-item-tag graph of FolkRank. Hence this paper proposes an improved FolkRank algorithm named FolkRank++, which fully considers the user-user and item-item internal relationships in tag recommendation by adding the correlation information between users or items. Based on the traditional FolkRank algorithm, an initial weight is also given to target user and target item's neighbors to supply the user-user and item-item relationships. The above work is mainly completed from two aspects: (1) Finding items similar to target item according to the attribute information, and obtaining similar users of the target user according to the history behavior of the user tagging items. (2) Calculating the weighted degree of items and users to evaluate their importance, then assigning initial weights to similar items and users. Experimental results show that this method has better recommendation performance.

  • This study divided employee performance factors into individual, organizational, and institutional factors, and empirically analyzed their relationship with performance evaluation results. Based on the final 417 samples, the results using the SPSS and AMOS are summarized as follows. Among the performance factors, job satisfaction and a fair performance system showed a significant positive (+) relationship with the individual performance evaluation results, and it was difficult to find a clear correlation with stable interpersonal relationships. Job satisfaction (β= 0.432, t= 7.375***) had the greatest impact, followed by a fair performance system (β= 0.127, t= 2.406*). This can be said to be the case where the cause of performance is satisfaction with the job and the recognition that the organization's performance system is fair. However, it was found that stable interpersonal relationships, that is, interpersonal relationships that have smooth relationships with other people and are accompanied by psychological stability, are not a performance factor. Based on the empirical analysis results, a discussion on performance factors, implications of this study, and future research directions are presented.

  • This study was to investigate the effects of interpersonal relationships on job satisfaction of home-visiting care helpers and the category of interpersonal relationships was subdivided into elderly clients, guardians, colleagues and directors considering the person-to-person nature of home-visiting care helper's job characteristics. A group of 336 care helpers who engaged in home-visiting care service providing facilities in Daejeon City was selected as a research subject, and the data were analyzed with SPSS 22.0 program using reliability, frequency, correlation and hierarchical multiple regression. The results for the final analysis revealed that the effect of socio-demographic features was not significant while, among characteristics of job performances, work priority, turnover experience, and career choice reasons turned out to have significant impacts on job satisfaction. In particular, interpersonal relationships except the one with guardians were found to be the most influential variables and the effects of those relationships on job satisfaction were significant. The influencing power was stronger in relationships with director, elderly clients, and colleagues in order, and the job satisfaction level was higher as they were in better relationships with director, elderly clients, and colleagues. The results of this research shows that it is necessary to set an atmosphere where harmonious interpersonal relationships can be formed inside and outside of facilities in order to improve job satisfaction of home-visiting care helpers.

  • This study examined the relationship between spirituality, social support, and interpersonal relationships in the workplace of art psychotherapists.The subjects were 114 art psychotherapists in the city of U. Frequency analysis, reliability analysis, correlation analysis, and multiple regression analysis were performed using the SPSS 22.0 program. First, regarding the effects of work spirituality of art psychotherapists on interpersonal relationships, the sub-factors of workplace spirituality (vocational consciousness, inner consciousness, and empathy consciousness) had a positive effect on interpersonal relationships. On the other hand, community consciousness and transcendence consciousness, which are sub-factors of workplace spirituality, do not appear to have a significant effect on interpersonal relationships. Second, regarding the effects of social support of art psychotherapists on interpersonal relations, the sub-factors of social support, such as evaluative support and material support, had a positive effect on interpersonal relationships. On the other hand, emotional support and informational support did not significantly affect interpersonal relationships. This means that higher vocational consciousness, inner consciousness, empathy consciousness, evaluative support, and material support factors of an artistic psychotherapist are conducive to better interpersonal relationships. This study provides basic data for preparing a plan to promote positive interpersonal relations among art psychotherapists.

Nurse's ethical value questionnaire was developed from review of literature and interview of nurses in the clinical settings. Content validity was tested from three nursing faculties and staffs. Ethical problems are categorized into four areas : 1) human life area 2) nurse-patient relationship area 3) nurse - nursing task relationship area 4) nurse-collegue relationship area The data were obtained from the 404 nurses in the clinical settings from Feb. to Mar. in 1990 by ethical value questionnaire. The analysis of data was done by Pearson's correlation coefficient, t-test, anova. The results of this study were as follows : 1. The ethical values of human life slightly took up the position of utilitarian. 2. The ethical values of nurse - patient relationships slightly took up deontological position. 3. The ethical values of nurse - nursing task relationships slightly took up deontological position. 4. The ethical values of nurse - colleague relationships greatly took up deontological position. 5. The ethics of nurses related to demographic characteristics of religion, attitude of nursing, ethical standards, education level and post. Those who have religion took up more deontological position than those who have not. Those who have positive attitude of nursing and firm ethical standards took up more deontological position than those who have not. Those who have higher education level and post took up more deontological position than those who have not.

  • This research aims to explore the relationships between 'teamwork skills' (often called team activity competence) and 'thinking styles' of engineering students in Korea, and to provide an explanation for the application of team-based environment as well as for the increase of teamwork skills. Teams and team activity are pervasive in today's organization and there has been relatively much research on teamwork skills and its related factors. However, to date, little attention has been paid to the teamwork skills, essential factor in team-based environment and its relationships with thinking styles. This study was conducted with 383 engineering students at P University, and students' teamwork skills as well as thinking styles have been measured before and after team-based learning class (hereafter TBL). Our findings show that firstly, there was a significant increase of teamwork skills between before and after TBL class. Second, team activity competence was found to have a higher correlation with most of creativity generating styles (i.e. legislative, judicial, hierarchical and global styles). Third, hierarchical style was found to influence team activity more than other components, and also legislative, external, global and judicial styles contributed to team-based activity. These findings are expected to provide an explanation for the application of thinking styles in team-based environment and will be useful for the improvement of related courses in engineering school.

  • The objective of this paper is the investigation of the relationships between the surface roughness and film evaporative characteristics of the surface. For example, when the droplet of liquid is in contact with the solid surface, its behavior strongly depends on the surface characteristics. The material properties and geometry - profile shape, waviness, roughness - of the surfaces have strongly influenced on the wettability of the droplet. To investigate the effect of the surface roughness on the film evaporation, firstly, the characteristics of wettabilities were studied according to contact angle and surface tree energy of specimens with various roughness heights. Secondly, the experimental test were carried out on capacities of the tubes diversly roughened by using different kinds of emery papers. Finally, the relationships between the film evaporation characteristics and surface roughness were explained by means of the correlation of contact angle and surface free energy with surface roughness and the influences of surface tree energy on the heat transfer performance.

  • The purpose of this study was to examine the relationships between child's self-regulation and stress according to child's sex. The subjects for this study were 380 children of 5-6th grade selected from elementary schools in Busan. Lee, Soon-Kyu's questionnaires(1994) on child's self-regulation and Han, Mi-Hyun's questionnaires(1996) on child's stress were used. Statistical techniques such as Manova, Pearson's correlation, multiple regression, canonical were used. The resets were as follows : (1) According to sex, there were significant differences in child's self-regulation and stress. The girls showed more self-regulation and higher friend-related stress than the boys. The boys showed higher parent-related stress than the girls. (2) Relationships between child's self-regulation and stress showed as follows : The boys who used more impulsive-control perceived lower friend-related stress, lower school-related stress, lower teacher-related stress, and lower surroundings-related stress. And the boys who used more behavioral-control perceived lower school-related stress, lower teacher-related stress, and lower surroundings-related stress. (3) The predicted variable for boy's friend-related stress was impulsive-control. The predicted variables for boy's school-related stress, teacher-related stress and surroundings-related stress were impulsive-control and behavioral-control. (4) Among three dimensions of self-regulation for boy, the effective variables were impulsive-control and behavioral-control. And among six dimensions of stress were surroundings-related stress, school-related stress and friend-related stress. Implications of this study were discussed in terms of child's self-regulation and stress.
