The purposes of this study are to derive supportive measures for the effective operation of vocational education and training high schools participating in the apprenticeship system (apprenticeship schools) and make policy suggestions by analyzing the need analysis and investigating the importance and the difficulty of teachers regarding the operation of those schools. To achieve these purposes, the study developed a questionnaire by deriving the areas and items for the operation of apprenticeship schools, and analyzed 121 completed questionnaires of head and senior teachers who manage the apprenticeship programs across the nation after conducting a survey. The findings of this study can be summarized as follows: First, the teachers of apprenticeship schools found all the operation areas of the schools are important but difficult. Out of the operation areas, teachers had relatively high needs for 'promotion, selection and management of enterprises', 'student management', 'development of apprenticeship programs, formation of the curriculum, and establishment of operation plans of the curriculum'. Second, the teachers found all the detailed items of the operation areas of apprenticeship schools are important but difficult generally. According to the results, it is required to relax the criteria for forming apprenticeship organizations; operate the local government-oriented apprenticeship system; establish information systems between schools and enterprises; improve the support methods of relevant agencies; and increase incentives of teachers who are in charge of apprenticeship programs. It is also necessary to operate exclusive agencies supporting for OJT; operate apprenticeship education centers of local small and medium-sized business associations; provide exclusive supervision of students; cultivate teachers who support industry-academia cooperation; and legislate on the NCS-based qualifications.

Multi-dimensional verbal short-term memory mechanisms are largely divided into the phonological channel and the lexical-semantic channel. The former is called phonological short-term memory and the latter is called semantic short-term memory. Phonological short-term memory is further segmented into the phonological input buffer and the phonological output buffer. In this study, the language performance of each of three patients with similar levels of conduction aphasia was analyzed in terms of multi-dimensional verbal short-term memory. To this end, three patients with conduction aphasia were instructed to perform four different aspects of language tasks that are spontaneous speaking, repetition, spontaneous writing, and dictation in both word and sentence level. Moreover, the patients' phonological memories and semantic short-term memories were evaluated using digit span tests and verbal learning tests. As a result, the three subjects exhibited various types of performances and error responses in the four aspects of language tests, and the short-term memory tests also did not produce identical results. The language performance of three patients with conduction aphasia can be explained according to whether the defects occurred in the semantic short-term memory, phonological input buffer and/or phonological output buffer. In this study, the relations between language and multi-dimensional verbal short-term memory were discussed based on the results of language tests and short-term memory tests in patients with conduction aphasia.

The purpose of this paper is to identify woodblocks which were engraved in the providences in the mid Chosun dynasty, especially ones engraved under the auspices of Yu Heui-chun(柳希春), but not listed in $\boxDr$Kosachwalyo 攷事撮要$\boxUl$. This could be done by the analyzing $\boxDr$The Diary of Miam 眉巖日記$\boxUl$ written by Yu Heui-chun. It is a book which recorded daily life of eminent scholar and official covering political, social and cultural aspects, books and family matters. There were two categories of books published under the auspices of Yu Heui-chun. One is the books written by his grandfather in law, Choi Bu(崔溥), which were $\boxDr$Keumnamjip 錦南集$\boxUl$ collective works of Choi Bu, and $\boxDr$Pyohaerog 漂海錄$\boxUl$, essays on travelling across China. The other is the books for children, $\boxDr$Sinjeung Yuhap 新增類合$\boxUl$ for teaching characters and $\boxDr$Sog Mong-gu 續蒙求$\boxUl$ for moral education. These woodblocks have to enlisted in the woodblock catalogs. The analysis shows that most of these woodblocks by Yu Heui-chun were not recorded in either of two $\boxDr$Kosachwalyo 攷事撮要$\boxUl$ editions published in 1575 and 1585. In this respect, $\boxDr$The Diary of Miam$\boxUl$ proved itself to be of great significance in terms of bibliography studies.

Even though software (SW) education has not been considered part of the current national kindergarten curriculum, in practice there is growing interest in adopting it. Teachers would be expected to play a key role in the successful introduction and implementation of new educational changes, such as SW education. In preparation for its adoption in ECE, it would be useful to determine ECE teachers' perception and attitudes toward early childhood software education. For this study, 219 ECE teachers' level of concern toward SW education was surveyed using the Stages of Concern Questionnaire. It was found that the teachers' level of concern was the highest at stage 0-Unconcerned and that they had high levels of stage management, personal and informational concern. Thus, a non-user pattern was mostly indicated. However, compared to the typical non-user pattern, the pattern aspect close to critical non-user ever appeared to some extent. In addition, a significant difference in the level of concern was shown at all stages depending on the awareness of the necessity for SW education. The teachers with SW training experience showed a higher intensity only at stage 0. There was a statistically significant difference in stages 0 and 6 depending on the future implementation decision. These results will be utilized as a resource in building an ECE teachers' support system according to their level of concern about SW education.

Six preservice teachers who participated in the "2016 service of summer vacation daycare programs by university and college students" focused on the programs for the formation of art, music and physical education and recreation culture were selected as research participants. The meaning of the experience they had through the service process was qualitatively analyzed. The subjects accepted the purpose of the self-directed service in which they should themselves solve a series of the entire process, from planning a volunteer program through drawing up the budget and purchasing materials to practice, evaluation and expressed the intention of participation. A volunteer program was conducted including visiting a daycare program for lower graders of elementary school (1st and 2nd grades) with more than 40 class hours during vacation. As research materials, research participants' journals, transcripts of individual interviews and group interviews, transcripts of phone calls, e-mail messages, and self-evaluation records of each class hour were collected. To increase the reliability and validity of the study, triangulation, member check, advice and review of the experts were conducted. In the study results, the volunteering experience-related significance for the preservice teachers who participated in the self-directed service were broadly categorized into 'Becoming a capable professional teacher', that consists of 'Increasing the power of thinking', 'Realizing the importance of communication', 'Doing together itself is important' and 'Ability to apply information and resources is needed'. 'Increase the continuity between preschool and elementary education' was subdivided into 'Get to know the necessity of the continuity between preschool and elementary education' and 'Want to learn the continuity between preschool and elementary education.'

Recent international environmental regulations are focused on reducing pre-contamination and on sustainable development prior to the usage stage of a product. The Environmental Performance Declaration is being used as a tool for quantifying the environmental performance of products, to reduce contamination in advance, and for advertising the results of railway vehicles in Europe. In this study, a life cycle assessment of the tilting train was conducted, the first such case study in Korea, according to the ISO 14025 standard and Korea EDP (Environmental Declaration of the Product) rule. As a result of the LCA, the life cycle carbon emission of the tilting train was determined to be $3.54{\times}10^7kgCO_2eq.$ which is higher than that of a European train. Also, the amount of $CO_2$ emission of the Mcp and car body is higher than that of the other car and bogie.

In this paper, we propose a hand tracking and gesture recognition system. Our system employs a depth capture device to obtain 3D geometric information of user's bare hand. In particular, we build a flexible tracking volume and restrict the hand tracking area, so that we can avoid diverse problems caused by conventional object detection/tracking systems. The proposed system computes running average of the hand position, and tracking volume is actively adjusted according to the statistical information that is computed on the basis of uncertainty of the user's hand motion in the 3D space. Once the position of user's hand is obtained, then the system attempts to detect stretched fingers to recognize finger gesture of the user's hand. In order to test the proposed framework, we built a NUI system using the proposed technique, and verified that our system presents very stable performance even in the case that multiple objects exist simultaneously in the crowded environment, as well as in the situation that the scene is occluded temporarily. We also verified that our system ensures running speed of 24-30 frames per second throughout the experiments.

The purpose of this study was to investigate the effects of educational training and psychosocial characteristics such as self-efficacy and social support on job involvement in dental hygienists. A total of 418 dental hygienists who were working in S, I and G area were recruited in this study. A self-administered questionnaire was used to evaluate individual and job characteristics, educational training, self-efficacy and social support of the study subjects. Hierarchical regression analysis was performed to examine the relationship of individual and job characteristics, educational training, self-efficacy and social support to job involvement. All statistical analyses were performed using the IBM SPSS Statistics ver. 20.0 for Windows, and p<0.05 was considered significant. The results show that learning experiences of liberal arts or social sciences as a part of college curriculum (t=-2.406), self-efficacy (t=3.728) and social support at work (t=4.391) were significantly associated with job involvement in dental hygienists. Dental hygienists who were having experiences of liberal arts or social sciences as a part of college curriculum, showing higher levels of self-efficacy, and receiving adequate social support from supervisors or coworkers at work were more likely to feel job involvement. They explained 17.4% of total variance of job involvement. This result suggests that experiences of liberal arts or social sciences as a part of college curriculum, higher levels of self-efficacy, and adequate social support from supervisors or coworkers at work might play an important role in increasing job involvement of dental hygienists. It is strongly required to develop individual and organizational program or training to promote a positive attitude to their job as a key professionals in the field of dental health, and to increase job involvement of dental hygienists.

The study aims to assess needs of administrative and financial support for effective performance of teacher professionalism of gifted. For this end, practicing teachers of gifted education were nationwide selected for survey questionnaires. The first survey of five-scale Likert item was conducted in July 2005 with 236 teachers and the second survey of open-ended item was done in November 2005 with 123 teachers. All the respondents provided their perceptions to current status of administrative and financial support for gifted education and needs for their effective performance of professionalism. Suggestions for improving conditions of administration and finance in terms of effective performance of teacher professionalism in gifted education were as follows: First, teachers should be assigned as full-time for gifted education. Otherwise, their teaching hours and other related jobs should be, reduced Second, the financial support for gifted education should be increased, in particular, more in provincial areas than metropolitan cities. Third, appropriate grouping and counseling according to diverse differences of students should be done. Fourth, understanding of principals and teachers in general education as well as parents and general public toward gifted education should be improved through inservice education program and other education programs. Further, teachers of gifted education should be provided with more frequent opportunities for participating inservice programs in quality, share knowledge and experiences among teachers through network systems, and be given appropriate incentives for better performance of professionalism.

This study examined the braking characteristics of a heavy haul freight train with P4a distribution valves applied to domestic high-speed freight trains. A freight train was composed of 50 cars, which is twice the normal operation. A braking test was performed to confirm the characteristics of the braking of a heavy haul. The brake cylinder pressures were measured for emergency and service braking on the 1st, 10th, 20th, 30th, and 50th cars. Because the brake signal is transmitted to the pressure through the braking tube connected to the end of the train, the rear vehicle is braking later than the vehicle ahead. Therefore, it is necessary to predict the brake pressures in all cars in a train to supplement the results of the limited tests and calculate the braking distance. The pressure in each car was determined using empirical models of linear interpolation, stepwise, and exponential models, which provided reliable information. The predictive results of the empirical models were compared with the measured results, and the exponential model was predicted relatively accurately. These results are expected to contribute to the safe operation of heavy haul freight trains and can be used to predict the braking distance and calculate the level of impact between vehicles during braking.
