A robot must be able to generate various skills to achieve given tasks intelligently and reasonably. The robot must first learn affordances to generate the skills. An affordance is defined as qualities of objects or environments that induce actions. Affordances can be usefully used to generate skills. Most tasks require sequential and goal-oriented behaviors. However, it is usually difficult to accomplish such tasks with affordances alone. To accomplish such tasks, a skill is constructed with an affordance and a soft behavioral motivation switch for reflecting goal-oriented elements. A skill calculates a behavioral motivation as a combination of both presently perceived information and goal-oriented elements. Here, a behavioral motivation is the internal condition that activates a goal-oriented behavior. In addition, a robot must be able to execute sequential behaviors. We construct skill networks by using generated skills that make action selection feasible to accomplish a task. A robot can select sequential and a goal-oriented behaviors using the skill network. For this, we will first propose a method for modeling and learning Bayesian networks that are used to generate affordances. To select sequential and goal-oriented behaviors, we construct skills using affordances and soft behavioral motivation switches. We also propose a method to generate the skill networks using the skills to execute given tasks. Finally, we will propose action-selection-mechanism to select sequential and goal-oriented behaviors using the skill network. To demonstrate the validity of our proposed methods, "Searching-for-a-target-object", "Approaching-a-target-object", "Sniffing-a-target-object", and "Kicking-a-target-object" affordances have been learned with GENIBO (pet robot) based on the human teaching method. Some experiments have also been performed with GENIBO using the skills and the skill networks.

Purpose: The purposes of this study were to compare the motivation for health behavior, health behaviors practices, and ADL of institutionalized elderly women with those of non-institutionalized elderly women. Methods: A cross-sectional descriptive survey was conducted in convenience samples of 144 aged women(80 institutionalized and 64 non-institutionalized) using structured questionnaires. Descriptive statistics, $x^2$-test, and ANCOVA were used for data analysis with SPSS program. Results: The institutionalized elderly reported significantly higher motivation than the non-institutionalized elderly. In subcategories of motivation, self-efficacy of the institutionalized elderly was significantly lower than that of the non-institutionalized elderly. The non-institutionalized elderly reported significantly lower perceived benefits and significantly higher perceived barriers than institutionalized elderly. The institutionalized elderly reported significantly lower health behaviors in exercise and nutrition than the non-institutionalized elderly. Among health behaviors of the non-institutionalized elderly women, stress management marked the lowest score. Conclusion: To enhance motivation of institutionalized elderly women, interventions for building self-efficacy are needed. To promote the health behavior of the non-institutionalized elderly, stress management programs are needed. All elderly women need exercise.

This study analyzes the differences in school life satisfaction according to middle school students' general characteristics, including their gender, grade, monthly household income, and parents' education level, and examines the effects of intimacy with parents, optimism, and learning motivation on school life satisfaction. Data were collected from 380 middle school students by using a socio-demographic questionnaire. A measurement tool for intimacy with parents, optimism, learning motivation, and school life satisfaction was used, and a frequency analysis, a t-test, a one-way ANOVA, a correlation analysis, and a path analysis were conducted. School life satisfaction showed differences in terms of middle school students grade and, parental education but there were no meaningful differences in terms of their gender and monthly household income. Intimacy with parents and optimism had direct effects on motivation; intimacy with the father and optimism had direct and indirect effects, respectively; and intimacy with the mother had an indirect effect. An increase in the level of intimacy between parents and students and an increase in the positive perception of oneself facilitated learning motivation as well as school life satisfaction.

It found that employee silence negatively impacts both organizations and their employees as shown in findings from many studies and recently there has been a growing interest in it. Silence is described as intentionally withholding job-related ideas, information, concerns, and opinions. Employee silence may decrease organizational change and innovation and reduce employee learning motivation and knowledge sharing engagement as well. The purpose of this study is to examine the relationships among silence motivations, perceived silence climate, and employee silence; the relationships among employee silence, learning inertia and knowledge sharing disengagement; the mediating role of employee silence between antecedents of employee silence and consequences additionally. The results that analyzed using data from 225 employees in 42 organizations are as follows. First, the impact of silence motivation and perceived silence climate on employee silence are positively significant. Second, the influence of defensive silence motivation on the acquiescent and relational silence motivation is positively significant. Third, the influence of employee silence on learning inertia and knowledge sharing disengagement is positively significant. Forth, employee silence mediates the relationship between silence motivation and perceived silence climate and learning inertia and knowledge sharing disengagement. These results suggest that employee silence is another strong expression and message for organizations to try to establish a learning organization from the perspective of knowledge management.

Purpose: The purposes of this study were to evaluate the degree of social support, self-esteem, and motivation for rehabilitation in stroke patients and examine correlations between activities of daily living and study variables. Furthermore, this study explored factors that influence on activities of daily living. Methods: The study population was 192 stroke patients admitted in two general hospitals and two rehabilitation hospitals in M city. We collected the data using the structured questionnaires from July 11 to September 30, 2013. Results: The higher degree of social support, self-esteem, motivation for rehabilitation, the higher performance level for activities of daily living. Influencing factors of activities of daily living in the participants were motivation for rehabilitation(${\beta}$=.32, p<.001) and social support(${\beta}$=.31, p<.001). The model explained 45.9% of the variance. Conclusion: This study shows that intrinsic motivation of change in stroke patients themselves, a strong will to return to society and social supports are important factors on activities of daily living. Therefore, it is needed to develop a systemic nursing intervention improving activities of daily living in stroke patients through positive social support from patients' family members and health care providers.

Purpose: This study examined whether the motivation for rehabilitation influences the functional performance of stroke patients. Methods: To elucidate the same, correlation analysis between the 'rehabilitation motivation level' and 'functional performance improvement' was performed. Thirty-three stroke patients, who were hospitalized in rehabilitation and nursing hospitals, were enrolled in this study. Functional performance was assessed using the 10MWT, FRT, and the BBS. Statistical analysis was performed to determine the correlation between the reactivation symptoms and rehabilitation therapy at four weeks, eight weeks, and 12 weeks. Results: The results showed a significant correlation between the reactivation symptoms and rehabilitation therapy, as evidenced by the 10MWT, FRT, and BBS (8-12 weeks 10M gait test, Berg balance scale for 4-8 weeks, and 8-12 weeks). The FRT did not reveal any significant correlation between the rehabilitation program and reactivation. Conclusion: The present study confirmed that a higher motivation for rehabilitation in stroke patients resulting in a higher likelihood of it acting as a factor in improving their functional ability. Based on the above-mentioned results, this study suggests that a rehabilitation program could be considered for the motivation of patients to participate in a rehabilitation program.
