In particular, for a practical mobile robot team to perform such a task as that of carrying out a search and rescue mission in a disaster area, the network connectivity and localization have to be guaranteed even in an environment where the network infrastructure is destroyed or a Global Positioning System is unavailable. This paper proposes the new collective intelligence network management architecture of multiple mobile robots supporting seamless network connectivity and cooperative localization. The proposed architecture includes a resource manager that makes the robots move around and not disconnect from the network link by considering the strength of the network signal and link quality. The location manager in the architecture supports localizing robots seamlessly by finding the relative locations of the robots as they move from a global outdoor environment to a local indoor position. The proposed schemes assuring network connectivity and localization were validated through numerical simulations and applied to a search and rescue robot team.

Contingency response in a FMS system requires that the system be able to identify and evaluate a number of alternatives. This paper is outlined that DSS completes with a problem processor in corporating Timed Petri Nets model, and a data base system. DSS enables the FMS user to get the maximum benefit from a FMS. The structure of this DSS parallels the organizational activities involved in running the FMS. In designing a shop floor controller for FMS, interactions between the different real time, discrete event functions must be established. The specification of the machine tool and material handling system functions working as a concurrent and cooperative system is given in terms of Timed Petri Nets. In addition, the basic concepts and uses of Petri Nets are surveyed. The system to be studied is first modelled by a Timed Petri Nets and then procedure for evaluating the FMS system performance are presented. Numerical examples are studied to illustrate a session of the FMS used-DSS interaction.

For the activation of the Sanhakyeon Consortium, the role of local universities is critical. It is necessary for the university professionals to bring forth detailed alternative plans to upgrade the technological power of the inferior local small & medium enterprises. This means that the local self-governing bodies must database local universities and professional personnel. As a result, the professionals that are needed by enterprises must be designated to those businesses. Also, the regional small and medium enterprises must develop research personnel to enhance their power of technology. To make this possible, the participating companies of Sanhakyeon Consortium should support the students who are participating in the Consortium with research funds, and also should consider how these students can work for those companies after graduation. Finally, the local self-governing bodies must support Sanhak's cooperative research on locally specialized Industries, by forming a technology-human power network between local universities and small Sl medium enterprises.

An emphasized analysis and reviews on the progress of pesticide managements for the past 10 years through the statistics in Korea are summarized in this continued studies in connection with the fundmental aspects and direction of advanced pesticide industry and improved plantprotection policies for 1980's. Remarkable development and changes are observed in the plant species and varieties, plantation practices and production techniques as well as pest infestations and controls in the last decade, but no normal achievement and operations are recognised on the pesticide management and marketing system especially. Realistic plant protection adminstration and pesticide regulations in accordance to the industrial modernization and pest management advancement must be adjusted in accordance with national economic progress and desirable agricultural structure for 1980's. Special considerations are stated on the strengthening of research and inspection program for the quality products and control with the efficacy and safety use of pesticides. More serious attentions are noted on the over production and flooded stocks under struggled market demands and sales competitions with lethal financial difficulties by producers. Through the status analyzed for the last decade, the integrated past management and cooperative basic control pattern under positive self-forecasting system by farmers are also urged for the effective and economic pest control measures. The problems and solutions discussed here ell the advanced pesticide management as well as the cooperation on the self-ordered quality control and market managing systems in 1980's as it is a desired projection for the further improvement. Most of outstanding and necessary statistics and data in the past decade are also summarized here for references in connection with the previous report.

Leaving the legacies of the Cold War and other difficulties behind them, South Korea and China are building up their successful strategic cooperative partnership, moving forward toward through the development of new economic exchanges and diplomatic cooperation between the two countries, and this process is expected to gain momentum during 2015. 2015 is the third year since President Park of South Korea and President Xi of China came into office, and also the first year they have begun to implement the many declarations and promises which they have made within the context of the strategic cooperative partnership. The two nations share a common cultural heritage, and their governments should take this opportunity to leverage their partnership to enhance their economies and to improve their people's quality of life, especially for the younger generation. At a summit held in July 2014, the two leaders agreed to launch a working-level group on maritime boundary delimitation. The first meeting took place on January 29, 2015, and addressed issues of Exclusive Economic Zones (EEZs) and continental shelves in the Yellow Sea, which has an area of about 380,000 ㎢. It is greatly to be hoped that the 2015 maritime boundary delimitation meeting between South Korea and China will not impair the future of bilateral relations, but rather will improve their prospects. South Korea and China must take the opportunity to secure a definitive delimitation of their maritime boundary; their strategic cooperative partnership is in good order and China is currently taking a somewhat more flexible stance on the ECS and the SCS, so an agreement on boundaries will serve as a useful model for regional maritime cooperation.

This study was conducted to investigate the effect of learning style and lecture attitude on academic achievement in non-face-to-face lectures. Among students attending H University in the first semester of 2020. 1,880 students voluntarily participated in the survey. The questionnaire consists of 33 questions, and actual GPA was used to determine academic achievement. In this study, ANOVA and regression were utilized to find out the factors affecting academic achievement. The results are as follows. First, in the correlation between learning style types, the higher the avoidant learning style, the lower the independent, cooperative, and competitive types. Second, the higher the independent learning type, the higher the positive lecture attitude and GPA, and the higher the type of cooperative learning, the higher the negative lecture attitude. Third, the positive attitudes of 4th graders were higher than that of 1st graders. Fourth, there was no difference in learning style between colleges. Fifth, independent/competitive learning styles and non-face-to-face lecture attitudes had a significant effect on academic achievement in non-face-to-face lectures. In conclusion, in order to narrow the academic gap, instructors must identify the type of learning style. And it is necessary to consider students' preferences for non-face-to-face lectures.

In many industries, competitive advantage is rapidly shifting to the management of suppliers. Especially, in the automotive industry, suppliers' manufacturing performance influences the quality of automobiles which are assembled by motor companies. This study seeks to identify dominant types of buyer-supplier relationships and to examine suppliers' performance difference according to types of buyer-supplier relationships. The findings indicate that the supplier's production performance in the cooperative relationship is higher than that of the suppliers in the other relationships. And then this study examines the relationships between interfirm asset specificity and suppliers' performance. The findings indicate that the greater the interfirm human asset cospecialization and physical asset specialization, the higher the supplier's market and production performance.
