Though there are many crimes on and out university campus in Korea, no one knows anything about the size or the types of campus crime. But, there are many theft crimes and sex assault in the library and one-room village near the university campus. This study suggested the establish ways and means needed to improve the campus security system, with the focus on the CPTED(Crime Prevention Through Environmental Design). Various types of crime prevention methods are being considered instead of conventional crime suppression measures. Among them, CPTED is drawing global attention. Crime prevention through environmental design is a multi-disciplinary approach to deterring criminal behavior through environmental design. CPTED strategies rely upon the ability to influence offender decisions that precede criminal acts. A truly safe campus can be achieved only through the cooperation of all students, faculty, staff and visitors. The cooperation and involvement of the entire campus community in campus crime prevention is absolutely necessary. University should adopt a series of policies and procedures designed to ensure that every possible precaution is taken to protect persons and property on campus.

Location-Based Services (LBSs) provide results to queries according to the location of the client issuing the query. In LBS, techniques such as caching and prefetching are effective approaches to reducing the data transmission from a server and query response time. However, they can lead to cache inefficiency and network overload due to the client's mobility and query pattern. To solve these drawbacks, we propose a semantic prefetching (SP) scheme using prefetching segment concept and improved cache replacement policies. When a mobile client enters a new service area, called semantic prefetching area, proposed scheme fetches the necessary semantic information from the server in advance. The mobile client maintains the information in its own cache for query processing of location-dependent data (LDD) in mobile computing environment. The performance of the proposed scheme is investigated in relation to various environmental variables, such as the mobility and query pattern of user, the distributions of LDDs and applied cache replacement strategies. Simulation results show that the proposed scheme is more efficient than the well-known existing scheme for range query and nearest neighbor query. In addition, applying the two queries dynamically to query processing improves the performance of the proposed scheme.

In this study, we simulated an amine regeneration process with heat-stable salts removal unit. We derived the optimal operating conditions considering the flow rate of waste, the removal rate of heat-stable salts, and the loss rate of MDEA (methyl diethanolamine). In the amine regeneration process that absorbs and removes acid gas, heat-stable salt impairs the absorption efficiency of process equipment and amine solution. An ion exchange resin method is to remove heat-stable salts through neutralization by using a strong base solution such as NaOH. The acid gas removal process was established using the Radfrac model, and the equilibrium constant of the reaction was calculated using Gibbs free energy. The removed amine solution is separated and flows to the heat-stable salts remover which is modeled by using the Rstoic model with neutralization reaction. Actual operation data and simulation results were compared and verified, and also a case study was conducted by adjusting the inflow mass of removal unit followed by suggesting optimal conditions.

In this study, we analyzed secondary science teachers' needs for mentoring programs improving their professionalism in science-gifted education. A survey was administered to 111 teachers who had experience in teaching science-gifted secondary students in Seoul. Analyses of the results indicated that most teachers needed the mentors' support in science content knowledge, knowledge of beliefs about science-gifted education, knowledge of science-gifted students, knowledge of instructional strategies for science-gifted education, knowledge of curriculum for science-gifted education, knowledge of assessment in science-gifted education, and knowledge of external factors influencing in implementing science-gifted education. Most teachers, especially having the perceptions of lower levels of professionalism, relatively needed more mentors' support in the knowledge of the instructional strategies for science-gifted education and the knowledge of assessment in science-gifted education. Most teachers wanted the mentors' supports for all subcategories of professionalism at the planning stage of the classes, and some did the support for some subcategories at the performance stage and the reflection-evaluation stage of the classes. They also relatively wanted more mentors' support for all subcategories of professionalism through lectures and/or group discussions, some did the support through face-to-face interviews and/or real-time or non real-time online interviews. They variously responded in the suitable ratio of mentors and mentees, and perceived positively the qualities required to mentor as well as the necessary factors for the effective use of mentoring.

This study was performed in order to suggest the future model of Asian universities that could be used in the planning of the global competitive strategy. Futurologists forecasted the future of higher education using Harman Fan Scenario as like this. First, most current universities will be 'the satellite university' until 2015. Second, they also will replace 'the bookless university' until 2020. Third, they will be 'no calendar university' until 2025. And then they may be 'all have access university' until 2030. After 2030, futurologists prospected that almost universities based on off-line campus will be disappeared into the history. The analysis method of Harman fan scenario and applied scenarios were also used to "A study on the future scenario of Korean university". The predictive model and the alternative models were explored in a view point of students, enterprise, and government. Individuality with educational excellence are standardized for learner, profit and effectiveness are applied for enterpriser, and equality with welfare are adapted for national leader. Asian universities need to focus on bringing up the practical ability based on conscious and emotional education instead of knowledge based on memory. Also they need to enforce the specialized education that can create new jobs through convergence of interdisciplinary. Especially, Asian nations need to explore, to find the strengthen area of their universities compared with USA. And these area should be specialized. The convergency strategy between oriental medicine and informatics is a meaningful sample. Based on this point, a predicted with 3 alternative scenarios in a view point of equality were suggested for the future of Asian universities.

The purpose of this convergence study was to examine the effects of smart learning on learner's participation, academic self-efficacy and task value in nursing education. The study was designed using a nonequivalent control group no-synchronized design. The subjects of this study consisted of 86 experimental group and 95 control group who were nursing students. Data were collected from March 2 to June 8. 2018. The data were analyzed using the spss 18.0 program to perform independent t-test. There were not statistically significant differences in learner's participation(t=1.065, p=.288) but were statistically significant differences in academic self-efficacy(t=2.668, p=.008) and task value(t=2.070, p=.040). Therefore, the smart learning was effective in increasing academic self-efficacy and task value for nursing students. The smart learning is expected to be useful as effective teaching and learning strategies in nursing education.

The purpose of this study was to examine the effects of flipped learning and explore the learners' experiences. Data were collected from 64 students who participated in flipped learning for 7 weeks at N university. The results were as follows. First, after applying flipped learning, learners feel more comfortable learning together and prefer collaborative learning. Second, flipped learning had no significant effects on learner's overall metacognition, but it had positive effects on the awareness and cognitive strategies. Third, flipped learning had no significant effects on academic self-efficacy, but it positively affected the task difficulty preference and confidence of learners who had a lower level of collaborative tendencies. Fourth, flipped learning had no significant effects on SDL ability, but it positively affected the learning plan of learners who had a higher level of collaborative tendencies. Fifth, learners' class satisfaction of flipped learning was generally very high. We suggested a policy, instructional design and strategies for effective implementation of flipped learning.

China's 'One Belt and One Load' initiative is a mega-infrastructure project that connects China and the Eurasian Economies Area by overland and sea routes. Therefore, if it goes smoothly, It will be a new engine for economic development in China and the world, and It is expected to be a factor that will change the structure of the international economy. Especially, the Eurasian continent is likely to develop into the center of the global economy. But China's 'One Belt and One Load' initiative is not only macro and long-term, but also implies complexity, making it hard to be optimistic about development. China's 'One Belt and One Load' initiative is not only strongly promoted as a long-term national development strategy to be completed by 2049, but also strong economic complementarity between China and 'One Belt and One Load' consecutive countries. And many of the successive countries are expecting 'One Belt and One Load' construction. Therefore, there is no possibility at all. In particular, the possibility of development can not be completely ruled out, given the various policies of 'One Belt and One Load' currently being pursued by China. Even if it doesn't go smoothly, the process alone will have significant economic effects on China and neighboring countries, so it will be meaningful. With the help of information technology.

This study generated primary data for supporting the place branding as a part of the library advertising and marketing strategies to increase public library visits. The literature review enabled the use of the place branding concepts to discover the relationships among the constituent parts, factors, expected outcomes, and loyalty, then to develop the research model and the hypothesis, which were verified using the Structural Equation Model. There were 34 research hypotheses, of which 21 were adopted. The place image factors such as library reliability, library reciprocity, and library safety were found to be significant. This study derived social contribution value as new place value and place image factors as the potential brand image of public libraries. It helped select the place image factors that best fit the local library's core values (i.e., place value). This study is meaningful because it is a fundamental study to introduce place branding in public libraries as an advertising and marketing strategy. And it is expected that public libraries will grow into high-quality brands with high awareness, loyalty, and secure leadership in the local community.

Recently, the satellite industry has been paying attention to the private-led 'New Space' paradigm, which is a departure from the traditional government-led industry. The space industry, which is considered to be the next food industry, is still receiving relatively little attention in Korea compared to the global market. Therefore, the purpose of this study is to explore future signals that can help determine the market entry strategies of private companies in the domestic satellite industry. To this end, this study utilizes the theoretical background of future signal theory and the Keyword Portfolio Map method to analyze keyword potential in patent document data based on keyword growth rate and keyword occurrence frequency. In addition, news data was collected to categorize future signals into first symptom and early information, respectively. This is utilized as an interpretive indicator of how the keywords reveal their actual potential outside of patent documents. This study describes the process of data collection and analysis to explore future signals and traces the evolution of each keyword in the collected documents from a weak signal to a strong signal by specifically visualizing how it can be used through the visualization of keyword maps. The process of this research can contribute to the methodological contribution and expansion of the scope of existing research on future signals, and the results can contribute to the establishment of new industry planning and research directions in the satellite industry.
