Cooperative coevolutionary algorithm (CCEA) has proven to be a very powerful means of solving optimization problems through problem decomposition. CCEA implies the use of several populations, each population having the aim of finding a partial solution for a component of the considered problem. Populations evolve separately and they interact only when individuals are evaluated. Interactions are made to obtain complete solutions by combining partial solutions, or collaborators, from each of the populations. In this respect, we can think of various interaction modes. The goal of this research is to develop a CCEA for a supply chain network design (SCND) problem and identify which interaction mode gives the best performance for this problem. We present general design principle of CCEA for the SCND problem, which require several co-evolving populations. We classify these populations into two groups and classify the collaborator selection scheme into two types, the random-based one and the best fitness-based one. By combining both two groups of population and two types of collaborator selection schemes, we consider four possible interaction modes. We also consider two modes of updating populations, the sequential mode and the parallel mode. Therefore, by combining both four possible interaction modes and two modes of updating populations, we investigate seven possible solution algorithms. Experiments for each of these solution algorithms are conducted on a few test problems. The results show that the mode of the best fitness-based collaborator applied to both groups of populations combined with the sequential update mode outperforms the other modes for all the test problems.

Korea has actively promoted the Comprehensive Plan for the e-Hub. The policies of Korean government could promote the e-business environment and market conditions in legal and infrastructure terms, but not much of business itself. The reason for this limited success in the e-Trade may result from the broken linkage between government policies and business strategies as well as the business and technical innovation. In this paper, we analyzes the more effective and economic solution for this recovery of broken link in terms of Metamediary. The most successful role of metamediary should compose of three functions - facilitator, collaborator and web service provider. Each of these function is clarified in more detail with the emphasis on the collaboration between the Universities and the government-supported corporations.

Following the collaborator meetings report towards practical engineering education at universities(June 2010), the Pioneering University Reform Project supported by The Ministry of Education, Culture, Sports, Science and Technology(MEXT) of Japan solicited opinions from industry, professional associations, and academia on the goals of the individual fields, as well as common goals, that could be adaptable and applicable for a broad range of universities and curricula. This paper gives an overview of two surveys that were conducted, as well as a summary of the mechanical engineering goals as an example of the individual fields.

A mechanical system controlled by human operator, such as master-slave system, includes human dynamics in the whole system and such a system is called a human-machine system. In the system, operator's skill is required considerably in order to realize a meaningful operation. In this paper, a new concept and design strategy of compensator that improves the operativity of human-machine system are proposed. The compensator is called "collaborater "that is named after "collaborator" who works together with people. We mean not to design the automatic controller but the compensator that works together with a machine so that human feels the fulfillment in the operation. Our aim is to realize cooperation of people and a machine on a higher level.

학술정보 통합관리시스템 OCEAN(Online Collaborator for society & Association Network of KISTI)은 학회정보화지원사업의 일환으로 학술정보를 통합관리하기 위해 2007년부터 사용된 통합관리 시스템이다. 구 OCEAN은 Struts2 프레임워크 기반으로 설계되어, 노후화된 프레임워크는 끊임없는 유지보수에도 급변하는 정보기술 환경에 낙후되었고, 보안적 측면 및 신규 기능 구현에 어려움이 있어 2차년도(2015~2016)에 걸친 시스템 재정비를 통해 최신 프레임워크를 적용하여 신규 시스템 설계하고 구축하였다.

Korean Government has been actively and aggressively promoted the global e-commerce (or e-trade). However, the global researches regard the Korea as the passive or retrogressive country in e-trade. The purpose of this study is to clarify the change of the policy paradigm on the e-trade of Korea and to search for new paradigm based on the total amendment (or inauguration) of the e-trade promotion law. The research concludes the current political paradigm on "the Designated total solution provider" should be separated from the e-trade infra or platform. More competitive and market-oriented paradigm of the promotion support on e-trade metamediary should be evaluated in terms of facilitator, service provider and collaborator.

The prosperity of modern society is heavily depending on communication technology. Communication is now expanding its roles from personal convenience to social/industrial functioning. Photonics was first introduced to communication in longdistance transmission area since it provided wide bandwidth cost-effectively. However, nowadays, photonics is not only a harmonious collaborator with electronics, but has its own exclusive playgrounds in various parts of communication. Limit-zero network pursues a network that can provide abundant capacity and efficiency using very limited resources. Photonics is the most promising candidate to accomplish the goal. In this article, we review the current status and predict the future contributions of photonics to limit-zero network.

The study of the modern art market and distribution differs in its research focus from that of traditional art history, which traces and analyzes the works of master artists, their schools and influence, in that it attempts to approach such issues as art and society, and distribution and consumption of works of art, based on new research methods and perspectives. This paper examines the life and art collection activities of Park Yeong-cheol, considered to be one of the earliest major modern Korean art collectors. He graduated from the Japanese military academy and served as both a solider of the Greater Korean Empire and a high level officer of the Japanese army. After being discharged, he served as Governor of Gangwon-do and then Hamgyeongbuk-do, and after his retirement from public office, he became a leading businessman. He is well-known as a Japanese sympathizer who approved of and advocated for the aggressive colonial policies of the Japanese empire. As a cultural enthusiast and art collector, however, Park Yeong-cheol published the most accurate edition of Yeonamjip, and donated his collection to Geyongseong University at the end of his life, thus providing the foundation for the Seoul National University Museum. All of these activities are highly commendable. His interest in growing his collection of paintings and calligraphies was largely motivated by his love of paintings and Chinese poems,but it also appears to have been the result of his active collaboration with the Japanese government's policy of trying to discover the distinct, non-western characteristics of traditional Eastern art.

Purpose: This study was performed to investigate the effects of a blended learning program on ethical values in undergraduate nursing students. Methods: This study was a one group pretest-posttest design. Seventy-one undergraduate nursing students who were taking a nursing ethics course at K University in S city were conveniently selected. The blended learning program was undertaken for 120 minutes one day weekly for 15 weeks. It consisted of case-based learning through an online method combined with problem-based learning offline. Scores for ethical value were measured using the ethical values scale. Results: The ethical values score increased significantly in the students after the blended learning (p=.004). Of the subgroup of ethical values human-life, relationship with collaborator, and nursing job scores increased significantly in students after the blended learning, respectively (p=.034; p<.001; p<.001), the score for area as relationship with nursing clients decreased significantly in the students after the blended learning (p<.001). Conclusion: The blended learning program was identified as an educational program which induces a positive effect on the development of ethical values in undergraduate nursing students, and in future it can be utilized in nursing ethics education.
