Recently there are growing needs and demand to enhance 'Unity of knowledge' as the concept of "Creating new value through integration and convergence" is developing rapidly in many different areas in the society. This also has significant implication to education. Especially, it requires paradigm shift in terms of required capabilities and qualifications for the students with science major. To accommodate this trend, Natural Sciences and Engineering's College has been increasing convergence education which focus on cultivating creative and cooperative learning capabilities as well as acquiring fundamental knowledge of individual majors. However, convergence education developed and implemented by Sciences college or liberal education so far has been mechanical combination of knowledge from different academic fields - not effectively integrated and interdisciplinary education. Given this situation, this research is to develop and propose a "convergence education program based on the development of scientific and cultural contents" as an education tool to enhance capabilities to apply and re-create integrated knowledge as well as acquire and learn existing knowledge. Education program developed in this research aims to achieve two different and sequential capabilities. First is to understand 'Science and Technology' and 'Cultural Archetype' which would be essential and useful to create cultural contents. Second is to develop capabilities to convert this understanding into cultural contents - a storytelling capability. This education program is differentiated in that it defines cultural contents as a medium to converge and integrate science and technology and humanities. By leveraging the concept of cultural content and storytelling, this education program would be able to overcome restrictions of existing interdisciplinary approach. Also, this program would encourage students to try in-depth research and new applications, and develop logical and creative thinking.

This study aims to identify and reduce the gaps of understandings and thoughts of river restoration between river engineers and ecologists by logically re-examining the definition and value of river restoration. For this purpose, function, and goods and services of river ecosystem are analyzed based on the study of those by de Groot et al. (2002). From the result of this analysis, definitions and strategies of presently-known river restoration and its similar activities are re-examined. Next, presently-known river restoration models, ERM (Ecological restoration model), ARM (Amenity restoration model) and semi-ERM (semi-Ecological restoration model), are reinforced in their frameworks. This study is expected to narrow the gap, between the professionals of different fields, of their understandings and thoughts of river restoration.

Recently, there are efforts to improve my learning ability by using various learning tools based on ICT technology. The application such as games is used in conjunction with lecture class to induce interest in the class and to enhance the learning effect by using smartphone app as learning tool. In addition, we are trying to improve creative thinking ability, problem solving ability and logical thinking ability through early coding education. In this paper, we describe the learning and quiz app using the app inventor and conducted the related questionnaire. We developed a learning philosophy for preliminary early childhood teachers using the developed apps and taught them how to utilize them in early childhood education by explaining the apps and using the app inventor. Through questionnaires, we confirmed the learning effect and the willingness to use in early childhood education. Through this study, I hope to improve the ability of early childhood teacher learning and to utilize the coding in early childhood education with the app developed as the app inventor.

Factors causing traffic accidents are various and traffic law violations can be among them. The efforts to increase traffic law obedience rates of drivers are common in many other countries to reduce traffic accidents, and one of generally applied methods is to increase the amounts of violation fines. Expensive levels of traffic law violation fines could have drivers choose "obey the law" in their decision-making stages since they are economically better-off by following the law. In this sense, this study has developed an economic model to verify whether the current levels of the traffic violation fines of Korea are effective for drivers to choose "obey-the-law" decisions. Speed violations and traffic signal violations have been selected for the case study to verify the relationships between "expected probabilities of being-caught" and "levels of violations fines".

The generation, verification and validation of Emergency Procedures for Nuclear Power Plant is a difficult and complex process. Atomic Energy Control Board(AECB) requires that emergency procedure and plan be produced before obtaining the Operating License, that is, detailed plans and procedures to handle emergency situations for both on-site actions and off-site actions be developed. In this report Emergency Operating Procedures Standard for Canadian Nuclear Utilities which makes reference to U. S. practices and the current direction of emergency procedures for CAN-DU reactors are reviewed and compared based on scope(events covered), methodology (event-oriented or symptom-oriented or hybrid) and format(method of presentation) preponderantly, and an attempt is made to integrate these procedures and as a result the recommended strategy for Wolsong unit 2, 3, & 4 is presented as event-specific procedures, generic procedures(when event is not diagnosed) and whose format is combination of logic diagram and text.

Typography is a subject of fundamental principle and considerable importance to the practice of design and visual language. In Typography education, we need to teach student with systematic, logic and holistic view prior to intuitive way. It must be emphasized as a foundation to all graphic design students who are familiar with digital media. despite the fact that high technology has invaded th design profession and the importance of learning how to deal with these new possibilities has grown, technological processes are not substituted nor are they excuses for not learning basic principles of Typography. Technology is merely and extension of these skills. The logic is objective and the intuition is subjective. Visual system exercises the student's ability to work objectively in thought and in method. Visual system presents the idea that logic and intuition can work together to give stronger results in problem solving than either can alone. I critically analyzed that what is system and how can we develop visual system which can be adapted to Typography education. I also have investigated visual system to find the possibility and flexibility in Typography education.

Programming learning tend to improve the high thinking ability by experiencing problem solving process through programming recently, There are the previous studies that small group cooperative learning has the effect of the learning that is based logical thinking and creativity, while programming learning has relied on individual learner's thinking and principles traditionally. In this paper, it was verified the effect on improving the problem solving ability to perform by the small cooperative learning group in a problem solving process of programming learning. For this, it was developed and applied a model that include small cooperative learning group based on the problem solving 5 steps. The results of this study showed that the small cooperative learning group has positive effect of the problem solving ability in programming learning and has no relationship with cognitive style.

Tangible programming tool based on a graphic interface platform is unlike programming on a computer due to the fact that young students can utilize their hands and tools without an on-line interface. This is effective in enhancing student understanding about difficult programming algorithms. B-Bricks was constructed to consolidate multiple commands onto one block, having immediate feedback about the result, and other algorithms based on assessing the problems that arose from the previous tangible block model. Upon experimenting on 29 students of grades 4th~6th, it was observed that as problems became more difficult, the accuracy of the answers derived diminished and their problem-solving time increased.

Since the introduction of smartphones, the introduction of charging cable infrastructure that can be used for public use is underway. Thanks to this, people use public cables comfortably without doubt, but most people are not aware of the dangers of public cables. These public cables can lead to infringement accidents such as personal information exposure due to the development of hacking cables, and in the worst case, hackers can take control of smartphones and laptops. This study analyzed the operating principles and attack principles of hacking cables that seem like these general charging cables, but contain malicious scripts or hardware inside. In addition, physical and logical countermeasures were considered based on the analysis.
