The purpose of this study is to provide necessary information to understand characteristics of vocational high school students and to enhance academic engagement through social support of teachers, leading to help research of teaching and learning strategy. A survey was conducted on 990 engineering major students attending 11 vocational high schools in Seoul metropolitan, Chungcheong, Jeolla, Kyeongsang and Kangwon regions. A questionnaire consists of measurement tools for the academic engagement (21 questions) and the social support of teachers (25 questions). The findings of this study are as follows: First, it is found that the level of students' academic engagement was high. But it appears that the students showed low engagement of emotion compared with that of behavior and cognition. There was no level difference according to gender, but there was a considerable difference according to a school year. The first year students' level of engagement was higher than the second and the third year students' in terms of cognition and emotion. Second, it shows that the level of the teachers' social support was normal, which was in the order of appraisal support, instrumental support, informational support, and emotional support. Especially, the level of appraisal support and instrumental support was most. Third, there were correlation and explanation between students' academic engagement and teachers' social support. Moreover, the result that teachers' emotional support has high correlation and explanation in qualitative terms of academic engagement support the importance. Therefore, it is concluded that the social support of teachers can make an positive influence on improving the academic engagement of students and provide students with adaptability and satisfaction with their school life, which may give students a positive effect in emotional development, self-formation, and complement.

This study aimed to investigate the relation between self-esteem and satisfaction. After gathering study subjects (exercise participants) and deciding the population in 2014 in Jeonbuk city area, convenience sampling method was used to analyze the date from 278 subjects. The retrieved questionnaire in the research was analyzed in Window SPSS version 21 statistical program. Frequency analysis, exploratory factor analysis, reliability analysis, and correlation analysis were used to find correlations between test values. Multiple regression analysis was used to find the effects of the test values. The study results are as follows. First, the exercise participants' positive self-esteem exhibited a positive relationship with competence, relatedness, and autonomy, which are sub factors of basic psychological needs satisfaction. Also, negative self-esteem had a negative relationship with competence, relatedness, and autonomy. Second, exercise participants' self-esteem had a positive effect on competence and autonomy in positive self-esteem and a negative effect on negative self-esteem. Relatedness had a positive effect in positive self-esteem but not in negative self-esteem. Thus it is necessary to increase positive self-esteem and make various exercise programs about basic psychological needs satisfaction of the exercise participants and strategic activity guide for exercise participants participating in exercise consistently.
This paper is to give Korean small and medium enterprises the direction for strengthening the competitiveness through looking the problems and improvements about the government policy that domestic small and medium enterprises is essential for the growth anc development. To derive these results, the theoretical background was established through considering the existing research literature. This paper has drawn the final policy alternatives through collecting field data and analysing the practical support after meeting with executives that are operating a small business related to research purposes. In this paper in order to strengthen the competitiveness of small and medium enterprises of the government's support policy, it is critical for the financial support policy and the tax support policiest policy. The conclusions in this study are following. SMEs in Korean economic growth contribute greatly to advance industrial structure, regional balanced development, employment opportunities and to alleviate the concentration of economic power. However, there are these positive, and the negative such as the absence of entrepreneurial spirit and passive participation in society. Therefore, SMEs now should have your own a lot of effort to improve their competitiveness. In addition, government believe that SMEs directly impact on the national economy, especially the people, but they still need systematic and aggressive policy support in the future because of the lack of the result. Finally, if they try strategic approach for several issues and improvement of government's support policy that this study suggested for SMEs, the entrance toward developed countries can be through jumping of Korean economy.

Baekdu-daegan is the greatest mountain chain as well as the major ecological axis of the Korean Peninsula. In recent year, however, this area is faced with the various kinds of developmental urge. To cope adequately with these problems, this study was executed to prepare synthetic and systematic management with conservation-oriented strategy for Baekdu-daegan and to suggest spatially definite zoning for the managerial area. This study is to take into consideration the traditional concepts of stream and watershed as well as the actual disturbance on Baekdu-daegan area. The study area is selected with semi-mountainous type, from Namdeokyusan to Sosagogae. To propose the process for reasonably establishing the managerial boundary adjacent to the Ridges, the analysis was carried out that ArcGIS was mainly used for its analysis with digital maps, Landsat TM image and ArcGIS Hydro Model. Landsat TM image was classified by 5 land use types such as cultivated land, urban area, barren area, water body and forest. Based on these analyses results, the managerial boundaries as alternatives from the Ridges were produced by watershed expansion process, and used for tracing the changes of areal ratio of various land use types to the relevant watersheds to search out the adequate managerial boundary. The results show that watershed expansion process could be effective tool for establishing the managerial boundary, and eighth expanded watershed toward Muju-Gun(west) and fifth expanded watershed toward Geochang-Gun(east) might be included for the adequate managerial boundary of the case site.

While most research focuses on the k-nearest neighbors (kNN) queries in the database community, an important type of proximity queries called k-farthest neighbors (kFN) queries has not received much attention. This paper addresses the problem of finding the k-farthest neighbors in road networks. Given a positive integer k, a query object q, and a set of data points P, a kFN query returns k data objects farthest from the query object q. Little attention has been paid to processing kFN queries in road networks. The challenge of processing kFN queries in road networks is reducing the number of network distance computations, which is the most prominent difference between a road network and a Euclidean space. In this study, we propose an efficient algorithm called FANS for k-FArthest Neighbor Search in road networks. We present a shared computation strategy to avoid redundant computation of the distances between a query object and data objects. We also present effective pruning techniques based on the maximum distance from a query object to data segments. Finally, we demonstrate the efficiency and scalability of our proposed solution with extensive experiments using real-world roadmaps.

Urban sprawl has been criticized due to its negative effects, including the encroachment of farmland and open spaces, the increase in traffic congestion and air pollution, the decline of central city, the decrease in social capital, and the unfairness of tax burdens on infrastructure and public services. This study measures urban sprawl in the capital region of South Korea where the characteristics of urban sprawl have been known to be different from those identified in the U.S. metropolitan areas. In particular, the study examines whether the capital region has experienced the decline of the central city with an expansion of low density residential development in suburban areas. Three measurements, the sprawl index with population density, the ratio of changes in urbanized areas to changes in population, and the population density gradient, were employed to measure urban sprawl, and GIS mapping and descriptive analysis were used to examine the central city decline and the characteristics of development patterns in suburban areas. The results show that the capital region of South Korea is moving to the American style sprawled development with the decline of the central city and an increase of single detached homes in suburban areas, implying that policy makers need to develop growth management strategies to prevent urban sprawl and its negative effects that many U.S. metropolitan areas have suffered from.
On Kawara's works are not only artworks but are also his personal daily records. He produced many artworks whose theme centered on his everyday life, a plan that he had precisely made. He selected several specific themes from his daily life: when and where he met someone, what he read, and where he traveled. Kawara constantly recorded his daily life using various types of unconventional medium: maps, postcards, and telegrams. Although he was occupied with recording his everyday life, he was also active in forming public opinions on various issues through social media. Kawara's works, which exhibit a distinctive characteristic of himself, could be classified as individual records because it includes an individual's daily life and selected issues. His artworks express concern for or expose the irrationality of his society, which encourages ordinary people to let their voices be heard and take part in public affairs. Thus, his works function not just as art but also as precious historical records.

The purpose of this study was to evaluate nursing educational objectives achievement, critical thinking disposition, and clinical competence and their relationships in nurses within five years after graduation. Subjects were 82 nurses who graduated one nursing college within five years and 68 managers in nursing unit of hospital. Questions were given to nurses. They reported their achievement of educational objectives of the nursing college, critical thinking disposition and clinical competence. Nursing unit managers received the same questions to evaluate nurses working at their unit. Data were collected from January to march 2014 and analyzed by descriptive statistics, t-test, ANOVA, Pearson correlation and multiple regression with SPSS/WIN 23.0 program. Mean scores for achievement of educational objectives, critical thinking disposition, and clinical competence were $3.60{\pm}0.60$, $3.46{\pm}0.28$, and $4.17{\pm}0.56$, respectively. Educational objectives achievement showed significant correlations with critical thinking disposition (r = 0.52, p <. 001) and clinical competence (r = 0.52, p < .001). Regression analysis showed that critical thinking disposition (${\beta}=.30$, p = .018) and clinical competence (${\beta}=.26$, p = .029) were significant factors for predicting educational objectives achievement. Manager's evaluation score for educational objectives achievement and clinical competence was higher than graduated nurses' report (p < .001). This could be used as a feed- back to reset educational objectives and upgrade the curriculum. These study results could be used to, establish strategies to improve educational objectives achievement.

Citizen participation and Living Lab are attracting interest as one of the major strategies for the success of smart cities. In a Living Lab, citizens, who are the end-users of technology, participate in the search for alternatives to define and solve problems and repeat experiments to verify alternatives in a circular process. The purpose of this research was to present an operating model of a citizen-participating online community platform to improve urban problems, implement and test it, and show its applicability. To this end, an operation model of a citizen-participating online community platform was proposed to improve urban problems. An online platform was designed and implemented to reflect the functions pursued by the operation model. Finally, a pilot test for the function was performed using the Oma Elementary School case located in Ilsan, Goyang-si, Gyeonggi-do. The operating model was designed with the city's pedestrian environment and children. As a result, the sharing and communicating process of urban issues among community members worked appropriately according to the designed intention. The Living Lab coordinator could visualize and view urban issues posted by users on a map based on location information. Visualizing the urban problem as a heat map confirmed that urban problems were concentrated in a specific area.
This study aims to find meaningful implications for the development of Korean elementary school math education courses and textbooks by comparing and analyzing the number and arithmetic areas of Korean and Canadian math textbooks in fifth and sixth grades. To this end, the textbook composition system of Korean and Canadian elementary schools was compared and analyzed, and the number and timing of introduction of math textbooks and math textbooks by grade, and the number in fifth and sixth grade and the learning contents of math textbooks were compared and analyzed. The following conclusions were obtained from this study: First, it is necessary to organize a textbook that can solve the problem in an integrated way by introducing the learned mathematical concepts and computations naturally in the context of problems closely related to real life, regardless of the type of private calculation or mathematics area. Second, it is necessary to organize questions using materials such as real photography and mathematics, science, technology, engineering, art, etc. and to organize textbooks that make people feel the necessity and usefulness of mathematics. Third, sufficient learning of the principles of mathematics through the use of various actual teaching aids and mathematical models, and the construction of textbooks focusing on problem-solving strategies using engineering tools are needed. Fourth, in-depth discussions are needed on the timing of learning guidance for fractions and minority learning or how to organize and develop learning content.
