In this study, we take into account in improving traffic flow in real-time problem. In order to solve the problem, we propose a new approach to manage traffic flow at the intersection in real-time via controlling by traffic light scheduling. In particular, the proposed method is based on process synchronization theory and connected vehicle technology where each vehicle is able to communicate with others. The traffic deadlock is also taken into consideration in case of high traffic volume. The simulation shows the potential results comparing with the existing traffic management system.

This study examined the role of contextual knowledge in cross-cultural communication between non-native speakers on an interactive web with a bulletin board system through which college students of English at Japanese and Korean universities interacted with each other discussing the topics of local and global issues. The study investigated the influence of students' relative contextual knowledge on active participation in interactions and discussed the results focusing on the use of discourse strategies for meaning negotiation. The study argues that in interactions even between non-native speakers with limited proficiency, contextual knowledge in the topic under discussion affects the degree to which they accommodate to each other during communication and suggests that the focus of teaching English as a foreign language also should be given to what kind of contextual knowledge students need to obtain and how to express it rather than what level of proficiency in English they need to acquire.

본 논문은 시간 기반의 약속 방법을 강조하는 시간제한적 협상구조를 소개한다. 에이전트들이 보내는 메세지에 약속기간을 첨부함으로써, 기존의 contact wet protocol(on)을 시간이 제약되어 있는 환경에서 효과적으로 사용될 수 있도록 확장할 수 있으며, 그로부터 시간제한적 협상 구조(TBNF: Time-Bounded Negotiation Framework)를 만들 수 있다. 이 논문에서는 약속기간을 가진 메시지를 의미론적으로 해석하고, 세가지 프로토콜 - 무보장 프로토콜, 승인보장 프로토콜, 그리고 유한시간 보장 프로토콜을 비교하는데, 이것들은 시간제한적 협상구조에 모두 포함될 수 있다. 제안된 협상 구조는 약속 기간 연장 요청이라는 새로운 메시지 유형과 부정적 약속(Negative Commitment)이라는 새로운 약속 개념을 가지고 있다. 시간제한적 협상 구조(TBNF)는 각 에이전트의 적응적 협상 전략을 수용하면서 효율적이며 효과적인 전자상거래 협상에 대한 구조를 제공할 것으로 예상되며, 이의 유용성을 평가하기 위해 실험결과를 비교 분석하였다.

The objective of this paper is to propose a Web-based Negotiation Support System(NSS) to facilitate conflict resolution between departments in a firm. As the management environment is recently becoming more complex and competitive, the need for harmonizing department functions in a firm is increasing much more than ever. In literature, most of conflict resolution approaches have been based on a sort of behavioral concepts including regular meeting or conference. However, as the department functions are wired through the Internet, a new approach to conflict resolution using the web-based technique is deemed necessary. For this purpose, we developed a Web NSS and illustrated a typical case in which conflicts between production and marketing functions are resolved using the Web NSS.

Since people have come to access more and more information about products with the proliferation of the Internet, more and more customer-to-customer e-marketplaces are being introduced with rapidly increasing transaction volumes. As the role of customer-to-customer electronic commerce has become increasingly regarded as vital to the economy, much research has delved into developing intelligent agent systems to efficiently support customer-to-customer electronic commerce. Most of this research, however, has focused only on supporting simple negotiation for the price of common goods along the time span. To expand the negotiation object to the differentiated goods, the customer must be allowed to negotiate over multi-at-tributes of the product besides the price, including the attributes related to the transaction activity itself, such as delivery time and payment method. To satisfy this requirement, we propose an agent marketplace for differentiated goods where the agent of a customer can negotiate not only the price but also the various attributes of the product and the transaction in order to achieve a better utility level for both buyer and seller. The formal protocol and the architecture issues to support the proposed e-marketplace and agents are also addressed.

As the terrorist act inflicted on the American Ambassador to Korea, Mark Lippert on March 5, 2015, the hunting rifle case in Sejong-si in which 3 persons were killed on February 25, and the hunting rifle murder case in Hwaseong-si Namyang-dong on February 27 occurred in succession, there is growing concern that our country is no long safe from firearm violence. Internationally, there is growing concern that our country is no longer safe from international terrorist organizations such as Islamic State (IS), the Sunni Muslims fundamentalists' Islamic militia group, which an 18-year old Korean boy Kim voluntarily joined in January 2015. The police crisis negotiation of our country was established and operated to prepare for the 1988 Olympic Games mainly for counter-terrorism purposes, and due to the characteristics of the prohibition of the use of guns, not a counter-terrorism incident has occurred, so the skepticism about its existence and the development directions are actively being discussed. Our country still prefers the traditional use of force such as SWAT team to resolve crisis case, such as such as murder, terrorism, robbery, and is reinforcing tactical capabilities. However, to perform the primary mission of the police to protect the people's lives and properties, it is necessary to establish the system in which crisis negotiations are possible in the initial stages no matter what incidents may occur by expanding the education for crisis negotiations techniques which are emphasized in the advanced countries such as the United States. In this research, the police department's internal education materials and media are analyzed so that the new police officers who work hardest on the forefront can carry out the roles as basic negotiators of crisis negotiations, and the measures for the development directions of the police crisis negotiations are presented.

본 논문에서는 협상에이전트를 기반으로 모바일 환경에서 개인 디지털 라이브러리 시스템을 구축하는 것에 관한 것을 연구하였다. 시스템 구축 실험결과 단일 에이전트를 사용한 것보다 멀티에이전트에서 협상에이전트를 사용한 것이 보다 높은 효율성을 보여주었음을 알 수 있었다.

In this study, the structure and role of governance system, which can be adapted as a effective way to negotiate the water resources related conflicts, was presented and the features and a characteristics of the various types of citizen participation model was analyzed. Also, the scientific approach based on Shared vision model, Game theory and Institutional design theory was introduced and applied to current conflict issues in Korea. The governance system with engineering negotiation model, which is presented in this study, can be used effectively in the field of water resources related conflicts to provide the scientific alternatives by participation of water related stakeholders.

Every medical school aims to provide better education, and it sometimes requires changing the current education system. However, an attempt for a change may not always be successful. In many cases, it is so not because an intended change was not properly directed but because conflicts in the process of adopting the change were not properly handled. This paper suggests seven points for how to successfully bring a change in medical education. First, the medical education should not simply focus on the pass rate of the national medical examination but also on the cultivation of creative leaders. Second, the faculty of medical school should be creative, self-motivated, and passionate. Third, people in charge of an intended change should have a good understanding of complicated dynamics between the dean's office, medical education experts, professors, and students. Fourth, people who are leading the change should also grasp the possibility that a well-intended change might not be well-received by professors, students, and dean due to their tendency to be complacent with the current system. Fifth, a successful introduction of a change requires good teamwork of a thinker, an actor, and a coordinator. Sixth, a change takes time as it takes place through a step-by-step process. Seventh, an attempt for a change accompanies a negotiation with professors with different thoughts and views regarding education, and people who want a change need to be flexible in that negotiation. In addition to these seven points, people who are responsible for a change should be consistent and consider the renown of the school.
