Analysis of variance has been applied as a new tool for precise substantiation of tabometric differences between Eustrongylides spinispiculum n. sp. and close species, as indicated by the polythetic divisive classificatory system. A revised key to the species of genus Eustrongylides Jagerski61d (1909) has been Presented.

The purpose of this study is to provide an opportunity for better understanding and application of 2009 revised elementary school mathematics textbooks through focus group's investigations on the elementary mathematics teacher's guide books. First, We survey previous studies on the teacher's guide books to make the frame of investigation. Next, We compose focus group(8 teachers) for 3~4th grades, and analyze the teacher's guide books according to ready-made frame: compliance of curriculum, accuracy and fairness of contents, selection and organization of contents. As results of investigation, system of organization of the teacher's guide books is needed. Goal, contents, teaching methods, and evaluations have to be consistent in describing mathematical terms. And errors in mathematics and mathematics education are examined more carefully. The teacher's guide books afford teachers many materials and informations to teach mathematics through classroom lessons. So more study on the teacher's guide books and developmental study for the model guidebooks is needed along with the revised curriculum and new textbooks.

China had revised Foreign Trade Law in order to fulfill its WTO commitments and duties, and fully exercise its rights and benefits as a WTO member. The main contents of the revised Foreign Trade Law as followed. For the first time, individuals are allowed to conduct foreign trade. Intellectual property is an important component of foreign trade, and protecting intellectual property rights is a key issue. A chapter on Intellectual property protection is one of the major additions to the Foreign Trade Law. New sections have also been added to allow and provide guidance for conducting investigations and seeking relief. Finally, the new law beefs up and clarifies enforcement procedures. It regulates the setting up of early warning and emergency systems and a foreign trade statistics system.

The Korean mathematical curriculum has been changed three times during the resent five years. It led to changes in textbook system. In the 2007 revised mathematics curriculum, workbook was developed focusing on student's self-oriented learning, effective practice in differentiated classroom, and mathematics problem solving considering individual difference. This paper examines the characteristics of the tasks and the way the tasks are organized in the textbooks and the workbook in accordance with the 2007 revised mathematics curriculum; comparing with the function section before and after the amendment. Researchers examine whether the textbook and workbook were accomplished the purpose with "cognitive expectation", "level of cognitive demand", "and "response types". Researchers revised framework of [Son, J. W. & Senk, S. (2010). How reform curricula in the USA and Korea present multiplication and division of fraction. Educ. Stud. Math 74(2), 117-142] to make them suitable for the function section at the seventh grade.

기록을 둘러싼 업무환경의 변화, 조직의 변화, 시스템의 변화 등은 기록에 대한 개념을 변화시켰다. 2001년도에 제정된 기록관리 국제표준인 ISO 15489 역시 이에 조응하기 위해 15년 만에 개정을 이루었다. 본 연구는 2016년에 개정된 기록관리 국제표준인 ISO 15489를 통해 급변하는 디지털 혁명 속에서 기록을 바라보는 개념의 변화를 살펴보고자 하였다. ISO 15489의 개정 배경 및 개정 전 후의 조항을 검토하고, 확장된 기록의 개념을 살펴봄으로써 구체적으로 개정판이 추구하는 바를 알아보고자 한다.

This study suggests a revised TAM (Technology Acceptance Model)-based performance evaluation model in MS (management science) education. Recently, many MS education programs are developed on the basis of computer and Internet communication technology. Previous researchers used TAM as an individual performance evaluation model, and proved that perceived usefulness and perceived ease of use are the substantive successful factors. This study provides a revised TAM-based conceptual framework for understanding what is involved in improving university MS education and what might be implied by conducting research on its improvement. It is argued in this research that three sets of forces and conditions have a direct and indirect impact on MS education ; first, each student has self efficacy and it is a critical determinant of behavior next, the use of Internet-based information system at MS education affects on the renewal of MS education : and finally, perceived usefulness and perceived ease of use have impacts on behavioral intention and actual system usage. This research concludes with suggestions for which direction this framework provides for future research on the premise and limits of efforts to renew MS education in university.

This study presents wrong hand calculations for fault analysis at field on the real AC railway system. Hence, we correctly revised the hand calculations. We propose AC railway system model by using EMTDC. Fault studies are performed. We also compare revised hand calculations with EMTDC simulation to verify the proposed model made by EMTDC. So, we can confirm that the model made by using EMTDC is correctly designed.

In this paper, we propose a new architecture of the Banyan switch for a high speed networking and the high speed parallel computer. The proposed switching network with a remodeled architecture is a newly modified Banyan network with eight input and output pots, respectively. We have analysed the maximum throughput of the revised switch. Our analyses has shown that under the uniform random traffic load, the FIFO discipline is limited to 70％. Therefore the result of the analyses shows that the results of the networking simulation with the new switch are feasible and if we adopt such as new architecture of the revised model of the Banyan switch, the hardware complexity can be reduced. The FIFO discipline has increased about 11% when we compare the switching system with the input buffer system. We have designed and verified the new switching system in VHDL.

In this paper, we propose and design new architecture of the modified Banyan switch for a high speed networking and the high speed parallel computer. The proposed switching network with a remodeled architecture is a newly modified Banyan network with eight input and output ports. The switch scheme is that two packets may arrive on different inputs destined for the same output. We have analyzed the maximum throughput of the revised switch. The result of the analyses shows good agreement simulation and if we adopt such architecture of the revised model of the Banyan switch, the hardware complexity can be reduced. The FIFO discipline has increased about lloio when we compare the switching system with the input buffer system. We have designed and verified the switching system in VHDL.
