The rapid progress of IT technologies promoted the foundation to offer users 'Any Time, Any Where, Any Service', and wireless internet services made it possible to use wired internet services while traveling. The previous academic administration management system having migrated from wired to wireless was dependent on mobile equipments' platform because of not being constructed on standard surroundings. And in the aspect of faculty system, course coordinator plays an significant role in building curricula and manage them, and finally counseling students with regard to them. But the course coordinator can't afford to advise students on which fields of their faculty fit them and which courses they have to take. We propose a mobile course coordinator system to help students learn profound courses of their major fields. Also the proposed system is implemented by using JAVA and WIPI technology, so that it is platform-independent. A mobile course coordinator system has an inference engine considering not only course trees which tell informations about the courses in every fields, but also personal courses that students have taken. The inference engine calculates three weights, representing the significance of each course considering every fields, the score of prerequisite courses which a student have taken, and the suitability in which department each student fits. When students apply for taking lectures, a mobile course coordinator system recommends them the most suitable courses. A mobile course coordinator system is able to substitute for the course coordinator who is counseling students. And the students with personal cellular phone are able to keep tracking their courses, and improve their knowledge about major with taking courses which the system's inference engine will advice.

Dr. Ranganathan's "Principles for Helpful Sequence" among the set of normative principles play an exclusive role in the arrangement of subject isolates. Each subject in the universe of subjects is regulated by a guiding principle of its own which analogously determines the sequence of Arrays in ordering the subject surrogates or isolates. For example, the "Principle of Later-in-Evolution" is applied for sequencing isolates of Animal and Plant Species; this concept can be applied to one of the tools of KOS viz. Taxonomies. The application of Principles for Helpful Sequence is summarily presented and in the process the paper highlights the inherent elements of knowledge organization in each one of these principles in a manner that might map the future course of research in this area with the potentiality to bring about a relation between principles for helpful sequence and KOS.

Contemporary society demands the ability to cope with the change competitively to the designer which is being accelerated of change and various media are emerging. The web design field which is one of the core design industry field of the contemporary society is needing the conversion from manufacturing technology specialization into creative design development composition. Generally, creative design development ability can be learned by studying. So, creativity development education is needed to develop creative design. Creative thought training is perceived as the core condition for competitive design and the education method for this is being proceeded multiply. But the study for design concept is lacking concretely. By this, this paper is to study the model which helps setting the design concept deduction creatively by instigating new ways of thought. The concept development process suggested in the study procedure systemizes the course for creative web design concept deduction and expects it to be utilized in design development to reinforce competitiveness.

This study divides and traces experience courses of families' disorganization and reorganization of North Korean refugees in North Korea, China, and South Korea after settlement respectively, from the course of their escaping North Korea to entering South Korea. Through these results, the study is to propose political implications. Main data for the study were analyzed through a case study as a qualitative study method, targeting eight people from July in 2012 to March in 2013. From the study result, though North Korean refugees seemed to disorganize and leave family relations in the course of escaping North Korea, it was found out that this is not disorganization but a preparatory stage which saves families standing at the crossroads of life and death and makes a chance to live with them someday. In these courses, in order for them to overcome their situations and survive, while repeating disorganization and reorganization of families, they used them as a way of saving themselves and their families. It was discovered that these phenomena always occurred simultaneously.

This research aims to contribute to the discipline of knowledge management (KM) in Higher Education (HE), and is conducted using the case of the study programme (SP) for Integrated Academic Studies (IAS) of Technics and Informatics (TI). A deduction-induction methodology is applied, using a Plan-Do-Check-Act (PDCA) approach to design a suitable KM concept for making improvements to the SP IAS TI on the standardisation platform. Based on the application of the International Classification of Standards (ICS), the research analyses the correlations and competences acquired during the courses within the accredited TI study programme of two-course studies. On the basis of the results of a comparative analysis of the developmental learning process and educational goals, it is shown that knowledge management in correlation with standardisation leads to the improvement of study programmes in the upcoming accreditation cycle on the standardisation platform. Frequent innovations within standardised thematic fields (daily, weekly, monthly, etc.) indicate the need for appropriate changes to the SP. The contribution to KM is through an original analysis of annual samples of more than 90,000 standardised sources in correlation with the TI study programme. Expert System (ES) modelling and the original results enable an analogous contribution to the future KM of other SPs.

The purpose of this study is to suggest necessity of idea expression method suitable for people in our country and deduct Graphic Ideation method by grasping problems of existing idea expression method. The idea expression method (association stimulating method, conceptual shifting method, information combination method) used by many graphic designers is effective in suggesting initial keyword, but has difficulty in the course of deducting the concept. Though deduction of core keyword is important to develop as a concept, the course of separation, combination in keyword connection play an important role, and most of idea expression methods are unavailable for suggesting concrete method for the course. Also as most of idea expression methods were developed and delivered in English-speaking world, it is suitable in English-speaking world culture which has thinking focused on words, but people in our country, which have thinking focusing on narration, cannot consider difference in language thinking due to limitation in idea for each stage. This study deducted idea expression method suitable for emotion of people in our country by proving the value of this idea expression method with style of suggesting and demonstrating 4 hypotheses in order to make the course for easy connection, separation, combination of keyword deducted by existing idea expression method, as well as suggesting idea expression method design based on these hypotheses. This idea expression method used rhetoric so that it is suitable for people our country who are strong for narration expression.

Objective: The aim of this study was to develop the assistive device for accelerator and brake pedals using bio-signals from the prefrontal lobe in the driving simulator and evaluate its performance. Background: There is lack of assistive devices for the driving in peoples with disabilities in Korea. However, if bio-signals and/or brain waves are used at driving a car, the people with serious physical limitations can improve their community mobility. Method: 15 subjects with driver's license participated in this study for experiment of driving performance evaluation in the simulator. Each subject drove the simulator the same course 10 times in three separated groups which use different interface controllers to accelerate and brake: (1) conventional pedal group, (2) joystick group and (3) bio-signal group(horizontal quick glance of the eyes and clench teeth). All experiments were recorded and the driving performances were evaluated by three inspectors. Results: Average score of bio-signal group for the driving in the simulator was increased 3% compared with the pedal group and was increased 9% compared with the joystick group(p<0.01). The subjects using bio-signals was decreased 44% in number of deduction compared with others because the device had the built-in modified cruise control. Conclusion: The assistive device for accelerator and brake pedals using bio-signals showed significantly better performance than using general pedal and a joystick interface(p<0.01). Application: This study can be used to design adaptive vehicle for driving in people with disabilities.

This study was carried out to evaluated for dewaterability of sewage sludge using waste oystershell and loess. The Jar-Test and the Buchner funnel test were proceeded for the assessment of dewaterability of a thickened sludge and digested sludge. TTF(Time to Filter), SRF(Specific Resistance to Filtration) were adopted as the valuation indices of sludge dewaterability. Dewatering conditioner which composed of both oystershell and loess is much dewaterable than the one composed of only oystershell. In the course of combining with oystershell and loess, the following fact was found that the dewaterability of the combination which have the higher ratio of oystershell than that of loess is superior. The most suitable oystershell :loess ratio of dewatering conditioner is 9:1 in treating both thickened sludge and digested sludge.
