The ship selection by consignors has two steps to carry their cargo. The first step is to select according to time schedule of ships and amount of cargo, and the second one is re-selection by concentrating different consignors' cargo into a unit that can be carried by single ship. Up to now, these steps are usually done by hands leading to inefficiency. The purpose of our paper is to form a logistics chain to minimize the overall sum of logistics cost by selecting ships for consignors' cargo using negotiation methodology between agents. Through concentration and distribution of cargo, maximization of global profit derived from searching optimal point in trade-off between inventory cost and freight rate cost. It is settled by the negotiation between consignors. In the experiments, two methods of the first-step of ship selection: EPDS(Earliest Possible Departure-Date Scheduling) and LPDS(Latest Possible Departure-Date Scheduling) coupled with the second-step ship concentration method using the negotiation were shown. From this, we deduced inventory cost, freight rates and logistics cost according SBF(Scheduling Bundle Factor) and analyzed the result. We found it will minimize the total logistics cost if we use negotiation method with EPDS.

As Electronic Commerce(EC) has been emerged and has developed, many researchers have tried to establish EC framework for automated contract and negotiation using agent technologies. Traditional researches, however, often had limitations. They often enforced the user's participations during the automated contract process of agents. They also could only consider a few of the user's requirements for a specific goods and did not have supported the procedures and methodologies for making the best contract. In this paper, we propose business model on EC based on multiagents to overcome the defects of the previous researches. We apply CSP techniques to brokerage process to satisfy various preferential requirements from the user. We also propose efficient negotiation mechanism using negotiation model of game theory. The contract candidates automatically negotiate and mediate in terms of their benefits through the proposed negotiation mechanism. For the optimal brokerage and automated negotiation, the agents process activities for contract on three layers, which are called competition layer, constraint satisfaction layer and negotiation layer in the proposed model. We also design the message driven communication protocol to support the automated contract among the agents. Finally, we have implemented prototype systems applying the proposed model and have shown the various experimental results for efficiency of the proposed model.

The Social Conflict Index in Korea is considerably high. In the situation where both parties' interests conflict each other, Korean society has shown immature democracy, which couldn't peacefully resolve the conflict because of the lack of tolerance against the counterparty's position. In terms of upbringing educated citizens, who could democratically communicate with others and approach problems, communication skill training is very important, reducing social costs by extreme conflict. Thus, this paper studied the necessity of communication skills training and its sociopolitical implication through case studies about "Communication and Negotiation" class, which is proceeded under university liberal education. Under current university curriculums, increased liberal education programs, related with speaking, focus on cultivating logical and critical thinking in the main. Based on these thinking skills, "Communication and Negotiation" has important implication in terms of cultivating mindset which resolves conflicts and considers other's position by collaborative and emotional perspectives. In terms of cultivating practical communication skills, this "Communication and Negotiation" class requires the change of teaching skills with various training programs, under students' active participation and feedback in the class exercise for resolving problems. Ultimately, through "Communication and Negotiation" class, and as members of society, students could learn matured citizenship and sense of responsibility by respecting others' position and reasonably resolving conflicts.

Most previous research on safer sex and condom use has been mainly focused on individual's dispositional factors such as attitudes, perceived control, intention, and etc. However, a few researchers recently started to propose that condom use is not a matter of individual behavioral decision but a product of serious interactive negotiation processes and condom negotiation would be the proximal key-determinant of condom use behaviors. The present research categorized condom-negotiation strategies and preferences of Korean college students and examined relationship between the strategies and other sex-related concepts. 186 participants' strategies on a free-response questions of condom negotiation revealed 7 types of persuasion strategies for condom use; Pregnancy risk, responsibility, care for partner, withholding sex, sexual disease, direct request, and sexual satisfaction (in order of preference). 6 types of persuasion strategies for condom avoid were abstracted: Pregnancy free, Sexual satisfaction, responsibility, direct request, unfaith toward condom, and withholding sex (in order of preference). The effects of gender, sexual experience, and culture were found and discussed in their implications for sexual education,

최근에 인터넷 기반의 상거래가 활발하게 진행되면서 공급자와 구매자간의 협상을 위한 연구 개발이 활발하게 진행이 되고 있다. 이러한 협상에는 여러 가지 방법들이 있지만 대부분을 그 고려 대상이 단순하거나, 개념적인 증명에 제한되는 경우가 많다. 따라서 본 논문에서는 협상 과정중에 발생하는 심리적인 환경을 속성화시켜서 그 가중치를 부여하는 방법을 제시함으로 함으로 협상의 진행을 효율성을 제시하고자 한다.

Task allocation is a key problem in multiagent systems. The importance of automated negotiation protocols for solving the task allocation problem is increasing as a consequence of increased multi-agent applications. In this paper, we introduce the multiagent Traveling Salesman Problem(TSP) as an example of task reallocation problem, and suggest Vickery auction as an inter-agent coordination mechanism for solving this problem. In order to apply this market-based coordination mechanism into multiagent TSPs, we define the profit of each agent, the ultimate goal of negotiation, cities to be traded out through auctions, the bidding strategy, and the order of auctions. The primary advantage of such approach is that it can find an optimal task allocation ...

The electronic commerce systems has been emerge in the field of commerce by making it possible to sell goods without the restriction of time and space. As the business based on the electronic commerce is increased, many studies related to the electronic commerce have been presented. In conventional electronic commerce systems, the buyers purchase some goods by using the information such as quality and price that are offered by the seller. In this paper we propose intelligent interface model that can satisfy the both sides.

본 연구는 스마트폰을 활용한 비면대면 협상 전략을 연구한 것이다. 컴퓨터와 인터넷의 발달로 인해 비즈니스 환경은 급변하고 있다. 전통적인 면대면 협상전략이 주로 오프라인적 관점에서 연구된 것이라면, 스마트폰을 활용한 비면대면 협상전략은 미디어를 활용한 온라인적 관점에서 연구된 것이다. 논의 결과 스마트폰을 활용한 비면대면 협상 전략은 미디어를 활용한 간접적인 협상으로 면대면 협상 전략의 장점을 극대화한 것으로 볼 수 있다.

In a magnetic train set composed of more than two cars, the installation of dampers between cars is carefully considered for improving both the ride quality and the safety, particularly during curve negotiation. In this study, a dynamic simulation of the ride quality and curve negotiation of a Maglev vehicle was carried out. The dynamic model is developed based on multibody dynamics. The presented full vehicle multibody dynamic model integrates the electromagnet model and its control algorithm. By using this model, the effects of the dampers are numerically analyzed. The proposed damper is installed on the vehicle and tested to analyze its effects. In this study, the simulation and measured results of the vehicle behavior and ride quality are discussed.

The purpose of this study was to investigate the impact of negotiation in Argument-Based Inquiry on students’ claim and evidence. A total of 126 first grade middle school students participated in this study and they performed five Argument-Based Inquiry (ABI) programs for one academic a year. To investigate the process of generating claim and evidence through the ABI, we interviewed students after they completed five ABI activities. The study findings showed that students ability to make claim and evidence improved as they progressed from individual activity to group activity in ABI activity and as ABI activities. The results also showed that students generated high level of claim and evidence through internal and external negotiation in ABI programs.
