Students obtain most concepts through textbooks, and teaching-learning activities between teachers and students. Accordingly, if science teachers already have misconceptions they will inevitably affect students' scientific concept. This study found many problems in teachers' cognition on the concepts of nuclear radiation. Because 12th grade physics II is classified as an optional subject in the 7th curriculum, teachers have few chances to teach it and, more importantly, have difficulty in teaching it because of the need to prepare students for the university entrance examination. The concept of radiation must be taught correctly because of its emergence in the 'environment' unit of 10th grade Science. Finally, results from this study can help science teachers teach these difficult concepts more correctly. In addition, results can also be useful in in-service retraining programs.

In this paper, we introduce a hierarchical internet application traffic classification system based on SVM as an alternative overcoming the uppermost limit of the conventional methodology which is using the port number or payload information. After selecting an optimal attribute subset of the bidirectional traffic flow data collected from the campus, the proposed system classifies the internet application traffic hierarchically. The system is composed of three layers: the first layer quickly determines P2P traffic and non-P2P traffic using a SVM, the second layer classifies P2P traffics into file-sharing, messenger, and TV, based on three SVDDs. The third layer makes specific classification of the entire 16 application traffics. By classifying the internet application traffic finely or coarsely, the proposed system can guarantee an efficient system resource management, a stable network environment, a seamless bandwidth, and an appropriate QoS. Also, even a new application traffic is added, it is possible to have a system incremental updating and scalability by training only a new SVDD without retraining the whole system. We validate the performance of our approach with computer experiments.

The purpose of the study was to investigate the perceptions of Elementary school teachers on mathematics instruction. To do this, 7 test items were developed to obtain data on teacher's perception of mathematics instruction and 73 teachers who take mathematical lesson analysis lectures were selected and conducted a survey. Since the data obtained are all qualitative data, they were analyzed through coding and similar responses were grouped into the same category. As a result of the survey, several facts were found as follow; First, When teachers thought about 'mathematics', the first words that come to mind were 'calculation', 'difficult', and 'logic'. It is necessary for the teacher to have positive thoughts on mathematics and mathematics learning, and this needs to be stressed enough in teacher education and teacher retraining. Second, the reason why mathematics is an important subject is 'because it is related to the real life', followed by 'because it gives rise to logical thinking ability' and 'because it gives rise to mathematical thinking ability'. These ideas are related to the cultivating mind value and the practical value of mathematics. In order for students to understand the various values of mathematics, teachers must understand the various values of mathematics. Third, the responses for reasons why elementary school students hate mathematics and are hard are because teachers demand 'thinking', 'because they repeat simple calculations', 'children hate complicated things', 'bother', 'Because mathematics itself is difficult', 'the level of curriculum and textbooks is high', and 'the amount of time and activity is too much'. These problems are likely to be improved by the implementation of revised 2015 national curriculum that emphasize core competence and process-based evaluation including mathematical processes. Fourth, the most common reason for failing elementary school mathematics instruction was 'because the process was difficult' and 'because of the results-based evaluation'. In addition, 'Results-oriented evaluation,' 'iterative calculation,' 'infused education,' 'failure to consider the level difference,' 'lack of conceptual and principle-centered education' were mentioned as a failure factor. Most of these factors can be changed by improving and changing teachers' teaching practice. Fifth, the responses for what does a desirable mathematics instruction look like are 'classroom related to real life', 'easy and fun mathematics lessons', 'class emphasizing understanding of principle', etc. Therefore, it is necessary to deeply deal with the related contents in the training courses for the improvement of the teachers' teaching practice, and it is necessary to support not only the one-time training but also the continuous professional development of teachers.

This study derived the policy implications and market strategies by analysis the e-book companies requirements & the CPND value chain structure, in order to revitalize the e-book market in Korea. Specifically, we examined the prospect of e-book market in Korea, current situations of production and distribution, awareness of service utilization and requirements for support policy with targets of 30 companies. As a research, the most needed item for e-book companies is 'PR and marketing support to enter and open the markets'(27%), which is the highest. 'Financial support such as labor costs and business expenses', 'support for retraining personnel to develop the expertise in respective fields' are followed and they account for 22%. Currently, the most effective support item is the external support program(35%) and funding power(30%) is followed. Unlike a paper book market, e-book is turned into a platform business in terms of the value chain. Based on these research content, e-book market activation and corporate competitive strategy was derived as follows : 1)literacy reinforcement about SNS marketing and e-pub3 authoring tool. 2)statistical DB construction of retail sales channels. 3)diversification of the billing system. 4)The quality of the e-book content certification.

Family companies are the unique industry-academic cooperation-related systems of Korean universities created by universities to promote various forms of industry-academic cooperation with companies. It is important to figure out the current status of family companies in order to understand the achievements of industrial-academic cooperation projects that have been actively pursued since the early 2000s. A lot of studies on industry-academic cooperation have focused mainly on the university's position. On the contrary, this study focuses on understanding the current status of the family company system and the status of industry-academic cooperation. Introduced in 2004, the Family Company System expanded rapidly as it was used as a performance indicator for college financial support projects related to industry-academic cooperation, with 174,425 companies registered as family companies as of 2017. A survey of family companies registered in universities carrying out the LINC+ project shows that companies registered in multiple universities are increasing, with relatively high demand and satisfaction for industry-academic cooperation among companies. Family companies were found to be relatively satisfied in terms of the use of R&D equipment or joint research, while they were relatively less satisfied in terms of workforce training and retraining. While companies have assessed product quality improvements through industry-academic cooperation, they have underestimated the effect of increasing sales and reducing production costs. Further, it was found that it was urgent to expand incentive systems and improve online information services to boost corporate participation in order to enhance the effectiveness of industry-academic cooperation.

This study has been carried out in an effort to bring light on the job scope which is required among the fashion models in Korea, then to sort out the concrete items of job pursuant to the job scope for the systemization of them. For this study, ten models who majored a fields of industry and the college in Korea, have gathered to analyze the job of the fashion models using the DACUM. As a result of it, the jobs of the fashion models have been classified into 7 duties and subsequent 86 tasks, while the fashion models entry jobs have been divided into 32 tasks(37.21%) that are necessary in the college before appointment. The result of analysis which investigates the relation between the significancy, the degree of difficulty and the frequency of the business, has it that the number of high-significancy business rises to 46 tasks(53.49%), high degree of difficulty business reaches to 21 tasks(24.41%), high frequency business is 18 tasks(20.93%), high degree of significancy and difficulty business stands at 13(15.12%), high significancy and frequency business amounts to 16 tasks(18.60%), and high degree of significancy, difficulty and frequency business reaches to 7 tasks(8.14%) respectively. These results should be actively reflected on the college curriculum before appointment, and on the job retraining courses for the incumbent fashion models, so as to enhance their job competency.

In this study, an investigation has been made on the status of the issuance of librarian qualification, the status of operating Subject specialized librarians at home and abroad, the status of professional manpower of the similar cultural facilities, and their recruitment method, based on which an attempt has been made to propose a way to nurture the Subject specialized librarians. First, I propose a method for training Subject specialized librarians through a regular curriculum and a retraining process, while suggest the ways to nurture the Subject specialized librarians from undergraduate and also nurture the existing librarians to become the Subject specialized librarians. Second, the basic qualification of the Subject specialized librarians must have a career of more than 3 years in a specific subject area with a master's degree or higher, and in order to have a subject area background, it is proposed that a bachelor's degree or a master's degree must absolutely be acquired in the corresponding subject area. Third, in order to improve the treatment of such Subject specialized librarians, the Subject specialized librarians in the administrative service group could be organized into a research librarian (or library and information science) series and types as a subordinate literary series under the researcher position. That is, it is proposed to differentiate the librarians and the Subject specialized librarians by reorganizing series and types of the Subject specialized librarians while maintaining the current librarian series.

The purpose of this study is to analyze current status and teacher librarians' perceptions of school library space composition and indoor environment, and propose some methods for the school library to be a basic educational facility. The space most secured by the 126 teacher librarians who participated in the survey was the free reading area, and the space with the lowest level was the media production and group project area. The most important types of spaces for teacher librarians are the teaching area and the free reading area, while the recognition of the importance of media production and group project areas is relatively low. Among the elements of indoor environmental assessment, they showed that safety and comfort were the most important but diversity and flexibility were relatively less important. The result of this analysis is different from the school and library policy direction that emphasizes the learning commons and maker spaces. Teacher librarians still seem to appreciate the importance of traditional library space. Therefore, it is necessary to include the establishment and operation of maker spaces and learning commons in the teacher librarians training and retraining process. In addition, it is necessary to increase the participation of users such as teachers, students, and parents in space composition and interior design initiatives to increase the user's interior environment satisfaction.

Background: The aim of this study was to determine the effectiveness of self-efficacy promoting pulmonary rehabilitation in patients with chronic obstructive pulmonary disease (COPD). Methods: thirty six patients, with clinically stable COPD were randomly assigned: 18 to a rehabilitation group and another 18 as a control group, The subjects participated in a the self-efficacy promoting pulmonary rehabilitation program for 8 weeks. This program consisted of education, breathing retraining, exercise training, relaxation and counseling. The control group received education only. The outcome variables were self-efficacy, dyspnea, exercise endurance, pulmonary function, and quality of life. Dyspnea was measured using the modified Borg scale. Exercise endurance was measured by the six minute walking distance. The quality of life was measured by the quality of life index for pulmonary disease patients. Results: In the rehabilitation group after performing the self-efficacy promoting pulmonary rehabilitation program, the self-efficacy score, exercise endurance, and quality of life score were higher than the control group (p=0.007, p=0.038, and p=0.039, respectively). and the exertional dyspnea score was significantly lower than controls(p=0.045). However, the dyspnea score and FEV1 were similar after performing the self-efficacy promoting pulmonary rehabilitation program. Conclusion: The self-efficacy promoting pulmonary rehabilitation program is effective to in improve self-efficacy, exertional dyspnea, exercise endurance and quality of life in patients with COPD.
