  • For successful implementation of robotic painting system, a structured design and analysis procedure is necessary. In designing robotic system, both functional and economical feasibility should be investigated. As the robotization is complicated task involving implemen- tation details (such as robot selection, accessory design, and spatial layout) together with operation details, the computer aided design and analysis method should be sought. However, conventional robotic design systems and off-line programming systems cannot accommodate these inquiries in a unified fashion. In this research, we develop an interactive design support system for robotization of a cycle painting line. With the developed system called SPRPL (Simulation Package for Robotic Painting Line) users can design the painting objects (via FRAME module), select robot model (ROBOT), design the part hanger (FEEDER), and arrange the workcell. After motion programming (MOTION), the design is evaluated in terms of: a) workpace analysis, b) coating thickness analysis, and c) cycle time (ANALYSIS).

  • This study was planned to investigate the relationship between development levels of learning organization and organization effectiveness in Hospital. Data were collected from 285 respondents who have participated in 'Learning Organization Project'(response rate =$50.5\%$). Structured questionnaire were applied by self administrated survey for two weeks since 2003 May. Main results were as follows; In the result of factor analysis, four factor were created and almost questionnaire items were classified into as same categories as theoretical concepts. Cronbach's a coefficient also showed over 0.7 in all categories. This result means that measurement tool to evaluate the development level of learning organization is valid and reliable. In the comparison of the development level of learning organization by participants' specialties, managerial workers perceived the lowest construction level, while medical technicians evaluated it as the highest level. In regression analysis, the perception levels of work environment, task and human aspect showed positive relationship with job competency significantly. For job satisfaction, levels of task and human aspects had positive relationship significantly. In addition, for organizational commitement, levels of organization and human aspect were positive predictors. Finally, for the satisfaction about experience of learning organization project, levels of environment, task and hmm aspects were related positively. We concluded from these result that the positive relationship between construction levels of learning organization and organization effectiveness was extended to hospital, besides industrial fields. We recommend the introduction and facilitation of learning organization project in various settings to improve the competency of knowledge management in individual and organizational levels.

  • Natural language processing (NLP) is utilized to understand a natural text. Text analysis systems use natural language algorithms to find the meaning of large amounts of text. Text classification represents a basic task of NLP with a wide range of applications such as topic labeling, sentiment analysis, spam detection, and intent detection. The algorithm can transform user's unstructured thoughts into more structured data. In this work, a text classifier has been developed that uses academic admission and registration texts as input, analyzes its content, and then automatically assigns relevant tags such as admission, graduate school, and registration. In this work, the well-known algorithms support vector machine SVM and K-nearest neighbor (kNN) algorithms are used to develop the above-mentioned classifier. The obtained results showed that the SVM classifier outperformed the kNN classifier with an overall accuracy of 98.9%. in addition, the mean absolute error of SVM was 0.0064 while it was 0.0098 for kNN classifier. Based on the obtained results, the SVM is used to implement the academic text classification in this work.

  • Students with learning disability have difficulty with attention and academic achievement Music can be an effective tool to enhance level of participation. The purpose of this study is to examine how much can be structured to enhance the attention span and related academic skills needed to achieve educational goals. The study has implemented structured music therapy sessions for three middle school students with learning disability. They participated in 20 sessions which were 30 minutes in length for ten weeks. The implemented music therapy sessions were designed using songs, playing, and listening to music. In order to test their level of attention, Frankfurter Aufmerksamkeits-Inventar(FAIR) Attention Test is implemented and Conners' Comprehensive Teacher's Rating Scale(CTRS-10) are used on the week before and after music activities. Also videotaping is used so as to analyze how correctly they do their task and how the correctness is changed period by period and to evaluate how often for ten minutes they make an eye contact with their teacher. The conclusions of this study are as follows: Firstly, the organized music activities have a positive affection on improving the attention of three middle school students who have learning disabilities. Fair Attention Test shows that they can do their task with more accuracy than in the previous period. Secondly, three students of this study improved their attention and made an eye contact more often than before this study, which is revealed through the analysis of the pre and post test results evaluated by CTRS-10. The results of the study indicate that structured use of music in various level of activities can help students to enhance attention span and the related academic skills.

  • The purpose of the present classroom research is to investigate teacher talk in the primary English classroom with special reference to teacher questions. The analysis of the recorded teacher questions reveals that the teacher asks a carefully structured sequence of questions leading to the clear pedagogical goals she has set: to encourage students to correct themselves; to find out what students know; to personalize the task; and to elicit culture talk. It is also shown that her use of display questions is supportive of learning; the teacher provides feedback in a way which is as communicative as possible in the context of the classroom and which facilitates the attainment of the pedagogical purposes. All these findings suggest that we consider how teacher talk may perform communicative functions in the classroom context rather terms defining communicative teacher talk purely in terms of the norms of communication outside the classroom.

  • The purpose of the study was to test the reliability and validity of the Korean version of Task Self-Efficacy Scale for activities of dally living (ADL). The Task Self-Efficacy Scale was developed by Roberts(1996) for low-intensity exercise study with older people to predict their performance of ADL. The scale was translated and back translated by bilingual persons, and then was modified to resolve variations in the translations. The Korean version of Self-Efficacy Scale for ADL was then administered to 193 elderly people including 95 hospitalized patients and 98 outpatients or healthy people. Face to face interview was used to fill out the structured questionnaire, and each interview took approximately 30 minutes. The subjects for the study were 80 women and 112 men with an age range of 65 to 95 years(M=71 years) of whom 82.6% classified themselves as moderate or quite active Most subjects(80.2%) had an education level of elementary school or less. The Self-Efficacy Scale for ADL is measured on a 0 to 10 VAS, assessing three areas of ADL : self care activities, household tasks, and motor tasks. The higher the score is, the higher person's confidence in performing ADL. Psychometric testing revealed that the scale was found to be internally consistent, showing a Cronbach's alpha of .97 The scale was significantly correlated with subjects' level of activity and subjective assessment of their health status. Moderate correlation with health-related hardiness scale also supported the validity. Factor analysis was performed to confirm whether the scale represents the three sub-areas as suggested in the literature. The results of the factor analysis led to a three factor solution according to Kaiser's criterion, but the items were not strongly and cleanly loaded for the third factor. This can be explained in that, among the three sub-ADL areas of the self-efficacy scale, the areas of self care activities and household tasks seem to have similar levels of difficulty in performance with not enough differences for the self-efficacy scale to distinguish between the two areas. Therefore, one factor solution was suggested since ADL can be seen as a unit of activities at similar level of difficulty in performance. One factor solution explained 68.1% of variance of the 19-item scale and all items were correlated over .6 with the factor, showing that the selected factor solution fits the model. The results indicated that the Korean version of Task Self-Efficacy Scale for ADL was reliable and valid in producing useful information to evaluate the effects of various interventions toward promoting health and quality of life for elderly people.

  • Purpose: This study was designed to measure the level of professional autonomy regarding physical therapists and to determine the association of organizational and occupational characteristics of the profession with its professional autonomy. Methods: We utilized a structured questionnaire survey of physical therapists (280 persons) in Jeju province. Data were collected from June 25 to July 14 in 2012. An additional 173 (63%) of them were used in the final analysis. Using PASW 18.0, descriptive and Hierarchical Linear Model were performed. Results: Regression analysis Result of Factors influencing Physiotherapist Professionalism, refresher training course (t=4.27), formalization (t=3.13), task significance (t=3.39), and autonomy (t=4.17) had a positive effect. Autonomy (${\beta}$=0.33) and formalization (${\beta}$=0.33) exerted the greatest influence. Conclusion: The survey regarding organizational and job characteristics showeds that occupational reeducation, formalization, and self- regulation constitute a positive part of what the professional autonomy is to be upheld. Results of the survey imply that in order to establish professional autonomy for the profession of physical therapist, the organization must make various efforts to beef up the exclusive knowledge and technology, and professional norms of the occupation that are considered essential for specific problem solving.
