In this study, I explored the causal relationship between acceptance attitudes and the expected effects of smart work. With the rapid development of smart technologies, lots of organizations try to innovate in the conventional working styles for maximizing organizational effectiveness and efficiency. Although many organizations wish to foster smart working environment, they don't have confidence in detailed action plans and effects from it. Therefore, this study that explores the causal relationship between acceptance attitudes and effects may have crucial meaning to organizations pursuing smart work. In this research empirically conducted by questionnaire survey, the acceptance attitudes as predictors and the expected effects of smart work as influenced variables were used. This research analyzed 118 collected data and multiple regression analysis. As a result of analysis, teleworking shows the positive relations to all of dependent variables. And others have a positive or negative influence on cognitive effects of smart work. Results of this study may give implications to organizations that want to implement smart work environment.

In this study event-related optical signals were extracted from the prefrontal cortexes using functional near infrared spectroscopy while subjects were carrying out 2-back working memory tasks. Four events such as start, yes, no, and error were considered based on the onsets of the stimulus, positive true responses, positive false responses, and negative responses in the 2-back working memory task, respectively. The optical signals recorded were analyzed by peri-event histograms and power spectrum distributions. The results showed specific characteristics of the event-related optical neuronal signals and an opened possibility of an application to control a non-invasive brain-computer interface system or an object of a virtual reality.

To prevent safety hazards in dangerous working area, we have proposed an intelligent image analysis system. Six common patterns of safety violations of workers' are defined and its motion detection algorithms are developed for alarm to CCTV monitoring system. Developed algorithms are implemented at 195 dangerous areas such as chemical and gas treated room. The results of violated motion detection ratio by developed system shows 94.95% of true positive cases, and 0.21% of false positive cases from all 587,645 event cases in one month implementation period. In the period, it is observed that the number of safety rule violations and the following accidents are decreased.

Classroom teachers measured children's social competence(SC). Thirty-two children were observed while they participated in cooperative art activities in homogeneous(high SC with high SC, or low SC with low SC) and heterogeneous(mixed SC) groups. Results showed that positive peer interaction was the most frequent type of interaction. Children with lower levels of social competence worked alone rather than in peer interaction. Children with higher levels of social competence showed more positive peer interaction. 'Imitating', a sub-item of dependent peer interaction, was most frequent in children with lower levels of social competence. Higher SC children maintained high SC regardless of grouping, but lower SC children showed significant differences in peer interaction between homogeneous and heterogeneous groups.

The purposes of this study were to Investigate the relationships between knitwear purchase motive and female consumer satisfaction, and to reveal how knitwear purchase motives and demographic variables influence the consumer satisfaction. The subjects were 263 female college students and working women residing in metropolitan area of Seoul. The data were analyzed by using descriptive analysis, factor analysis, Cronbach's ${\alpha}$-reliability coefficient, t-test, Pearson's correlation coefficient, and multiple regression analysis. Five dimensions of knitwear purchase motive were derived by factor analysis; expressive, others' influence/deficiency, quality/social, situation, and utility motive. Consumer satisfactions were classified into 3 dimensions; appearance, practicality, and quality satisfaction. The expressive motive had significant positive relationships with the satisfaction of appearance and quality satisfaction. The quality/social motive had positive relationships with the satisfaction of appearance, practicality, and quality. Utility motive had positive relationships with the satisfaction of appearance and practicality. Working women had higher situation motive and quality/social motive than the female college students had. The higher the age was, the higher the score on situation motive and quality/social motive were. The higher the social class was, the higher the score on expressive motive was. The higher the income was, the higher the score on appearance, practicality, and quality satisfaction were. The consumer satisfaction of knitwear was influenced most by the quality/social motive and next by the expressive motive, the income, and the utility motive in order.
