The background of this study was the fact that the religious spaces require sacred space devices in addition to aesthetic aspects. This study began with the definition that 'philosophical phenomenology provides one of the theoretical frameworks for religious phenomenology'. Seeing that 'philosophical phenomenology has limitations in drawing out the characteristics, this study attempted to study religious spaces through the method of specialized and refined religious phenomenology for the religious spaces alone. The purpose of this study was to understand the characteristics of religious spaces and the fact that the religious spaces are divided into 'profane' domains and 'sacred' ones and to analyze the characteristics of space and light in terms of religious phenomenology through Dutch religious architect Dom Hans van der Laan's architectural projects of monasteries. The study method was to present the relationship between space and light in terms of religious phenomenology and to summarize Van der Laan's interpretational method of the religious spaces through the architect's life and architectural philosophy.The conclusion of this study was that Dom Hans van der Laan's entire works were judged to have sufficient research value in studying the religious spaces as they were all created in the special category of 'religion'. With his project, it is possible for us to study 'hierophany' as experience of space and light through the methodology of religious phenomenology. This study has significant meaning in that it introduced an architect of religious spaces and a related new view on architecture.

The purpose of this study was to develop an educational program designed to allow students to experience 'up-cycling' first-hand during class and understand its significance by helping them improving their practical problem-solving abilities. Teachers of home economics, Korean, and social studies to third grade middle schooler were asked to analyze the curriculums of their subjects. The analysis results were then used to identify common elements among the units, reconstruct the curriculums, and develop an integrated lesson program to offer integrated activities. Based on these, a lesson program was developed to make an eco-bag and running shoes under the theme of 'up-cycling' in the unit of 'environmentally-friendly clothing and mending of clothes' in the home economics subject. The results were as follows: First, a topical fusion lesson program was developed to integrate three subjects together. The development process involved the integration of the topic of up-cycling, a program model for integrated lessons, and a teaching and learning process plan for topical integrated education. Secondly, a lesson program for home economics was developed that was applicable to actual home economics lessons based on the topical integrated lesson program. The lesson domains were divided into large, medium, and small to create a ten-lesson teaching and learning process plan needed for the lessons, teaching materials that could be put to actual uses in lessons, and activity and evaluation logs for learners.

Purpose - The current distribution enterprises have realized the necessity for integrated and specialized images in their stores. From those reasons, visual merchandising has been considered as a powerful means towards brand value judgement as well as maximizing both brand and corporate identity. This research intends to study and discuss the current situations in Korean visual merchandising and its future concept setting. Based on the research findings, this paper tries to propose the basic concept for development strategies of visual merchandising in Korean distribution market. Although the studies on visual merchandising in Korean traditional markets have been continued, visual merchandisers have been distorted by display control centers in real situations. Therefore, this study tries to set both current and future concepts in visual merchandising for further discussions and a new complement formulation. Research design, data, and methodology - This study has investigated previous studies with the way of normative study by comparing, organizing concepts and relating terms on visual merchandising. In order to be an exact research, it seems to be more appropriate to analyze this study with a deductive analysis way rather than inductive as for getting the core of visual merchandising. Besides, this study changed the term 'visual merchandising' into 'VMD', and used it as an unified one. Results - Visual merchandising has an important key in retail planning. With focusing on organizing visual merchandising concepts, it should be adequate for domestic circumstances because there are various visual merchandising concepts with different perspectives. Thus, it is necessary to establish a concept including modern and Korean features through previous studies and data. Visual merchandising can be defined as followings. It enhances the value of shop images from visual aspects and conveys brand concepts effectively. Its task is to plan and manage products sales by combining three merchandising domains such as interior, display, and merchandising. Conclusions - There are some limitations on setting academic concepts in visual merchandising due to its features as to be taken in the field focused studies. More meaningful case studies should be performed as an area of future studies. Therefore, it is necessary to perform an effectiveness analysis on empirical visual merchandising state and present the course of development.

Purpose: The present study aimed to review the characteristics of cognitive behavioral therapy (CBT) programs for alcohol use disorders and to examine the outcomes of such programs. Methods: We searched for domestic and foreign studies that implemented a CBT program for alcohol use disorders, published from 2006 to 2017. Studies that met inclusion/exclusion criteria were selected and a quality assessment was performed using the Risk of Bias (RoB) and Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS) instruments. We utilized a five-stage analysis process, through which nine experimental studies were selected. Results: Of these nine studies, four were randomized controlled trials, four used a quasi-experimental design, and one used a qualitative design. The CBT involved the three domains of cognitive reconstruction, problem solving, and coping. Coping with drinking situations and communication constituted most of the sessions. The outcomes of such interventions showed that CBT had a positive effect on alcohol use and self-evaluation. Conclusion: CBT is an effective way to change alcohol use behaviors, motivation, interpersonal relationships, emotional control, and self-efficacy among patients with alcohol use disorders. This study provides evidence for the effectiveness of CBT-based programs for the treatment of alcohol use disorders.

Permanent magnet sodium flowmeter (PMSF) have been used to measure the sodium flow in fast breeder reactors. Due to the effects of irradiation, thermal cycling, time lapse, etc., the magnetic flux density of the PMSF will decrease after being used in the reactor for a period of time. Therefore, it must be calibrated regularly. But some flowmeters that immersed in sodium cannot be removed for an off-line calibration, so the on-line calibration is required. However, the best online calibration accuracy of PMSF using cross-correlation analysis method was 2.0-level without considering the repeatability. In order to further improve this work, the operational principle of the transducer in PMSF is analyzed and the design principle of the transducer is proposed. The transducers were tested on the sodium flow loop to collect the experimental data. The signal characteristics are analyzed from the time and frequency domains, respectively. The cross-correlation analysis method based on biased estimation is adopted to obtain the flow rate. The verification experimental results showed that the measurement accuracy is 1.0-level when the flow velocity is above 0.5 m/s, and the measurement accuracy is 3.0-level when the flow velocity is in the range of 0.2 m/s to 0.5 m/s.

An overall responding security-centered framework is necessary required for infringement accidents, failures, and cyber threats. On the other hand, the correspondence structures of existing administrative, technical, physical security have weakness in a system responding to complex attacks because each step is performed independently. This study will recognize all internal and external users as a potentially threatening element. To perform connectivity analysis regarding an action, an intelligent convergence security framework and road map is suggested. A suggested convergence security framework was constructed to be independent of an automatic framework, such as the conventional single solution for the priority defense system of APT of the latest attack type, which makes continuous reputational attacks to achieve its goals. This study suggested the next generation convergence security framework to have preemptive responses, possibly against an APT attack, consisting of the following five hierarchical layers: domain security, domain connection, action visibility, action control, and convergence correspondence. In the domain, the connection layer suggests a security instruction and direction in the domains of administrative, physical and technical security. The domain security layer has consistency of status information among the security domain. A visibility layer of an intelligent attack action consists of data gathering, comparison and decision cycle. The action control layer is a layer that controls the visibility action. Finally, the convergence corresponding layer suggests a corresponding system of before and after an APT attack. The administrative security domain had a security design based on organization, rule, process, and paper information. The physical security domain is designed to separate into a control layer and facility according to the threats of the control impossible and control possible. Each domain action executes visible and control steps, and is designed to have flexibility regarding security environmental changes. In this study, the framework to address an APT attack and load map will be used as an infrastructure corresponding to the next generation security.

Purpose: The purpose of this study was to design a mobile-application of a cognitive training program for people who have chemo-related cognitive complaints. Methods: The program was developed based on the network-based instructional system design proposed by Jung. The program consisted of several tasks centered on four cognitive domains: learning, memory, working memory, and attention. For memory learning, a target-image and all its elements (color, position, and number) were presented on the screen that had to be recognized among a number of distractor-figures. In working memory training, the previous learned target-figure according to the level of difficulty had to be remembered among many different figures. In attention training named "Find the same figure," two identical symbols in a grid-pattern filled with different images were presented on the screen, and these had to be simultaneously touched. In attention training named "Find the different figure," a different symbol in a grid pattern filled with same figures had to be selected. This program was developed to train for a minimum of 20 min/day, four days/week for six weeks. Results: This cognitive training revealed statistically significant improvement in subjective cognitive impairments (t=3.88, p=.006) at six weeks in eight cancer survivors. Conclusion: This cognitive training program is expected to offer individualized training opportunities for improving cognitive function and further research is needed to test the effect in various settings.
