Due to the division of China's departmental laws, the disconnect between theory and practice, and the influence of traditional academic thinking on the understanding of the knowledge structure of arbitration legal talents in practice, the construction of law school colleges, teaching teams, and research centers mostly revolves around departmental laws, tearing the connection of the arbitration legal system. The student-centered, process-guaranteed, and result-oriented arbitration master of law training model is "virtualized," the shaping of arbitration professionalism is ignored, the coverage of practical teaching is narrowed, and the arbitration legal profession is mostly formalized. The prevalence of specialized curriculum systems shortage, single faculty, formalized practical teaching, outdated curriculum settings, unsuitable curriculum system design for development, and inaccurate professional curriculum standards and positioning renders it difficult to integrate the "Belt and Road." The cutting-edge, the latest research results, and practical experience cannot reflect the connotation, goals, and requirements of "Entrepreneurship" education, as well as arbitral issues such as the ineffective monitoring of practical education and the inconsistent evaluation of standards and scales. Under the background of the "Belt and Road," based on system theory and practice and through training goals that innovate and initiate organizational form, activity content, management characteristics, assessment and support conditions, etc., the arbitration law teaching curriculum system is gradually improved and integrated. Through the establishment of a "Belt and Road" arbitration case file database and other measures, a complete arbitration law theory and practice teaching guarantee system has been established. Third parties are introduced, arbitration law experimental modules are developed, students are guided how to discover new knowledge, new contents are mastered, solidarity, cooperation, and problem-solving capabilities are cultivated in the practice of the "Belt and Road," and quality education, vocational education, and innovation education are organically integrated. In order to implement the requirements of arbitration law education, innovation development and collaborative management of arbitration law teaching practice base should be cultivated, thus giving full play to the effect of collaborative education between universities and arbitration institutions.

Cognitive radio (CR) technology is an effective solution to the spectrum scarcity issue. Collaborative spectrum sensing is known as a promising technique to improve the performance of spectrum sensing in cognitive radio networks (CRNs). However, collaborative spectrum sensing is vulnerable to spectrum data falsification (SSDF) attack, where malicious users (MUs) may send false sensing data to mislead other secondary users (SUs) to make an incorrect decision about primary user (PUs) activity, which is one of the key adversaries to the performance of CRNs. In this paper, we propose a coalition based malicious users detection (CMD) algorithm to detect the malicious user in CRNs. The proposed CMD algorithm can efficiently detect MUs base on the Geary'C theory and be modeled as a coalition formation game. Specifically, SSDF attack is one of the key issues to affect the resource allocation process. Focusing on the security issues, in this paper, we analyze the power allocation problem with MUs, and propose MUs detection based power allocation (MPA) algorithm. The MPA algorithm is divided into two steps: the MUs detection step and the optimal power allocation step. Firstly, in the MUs detection step, by the CMD algorithm we can obtain the MUs detection probability and the energy consumption of MUs detection. Secondly, in the optimal power allocation step, we use the Lagrange dual decomposition method to obtain the optimal transmission power of each SU and achieve the maximum utility of the whole CRN. Numerical simulation results show that the proposed CMD and MPA scheme can achieve a considerable performance improvement in MUs detection and power allocation.

본 논문에서는 무선센서네트워크에서 이루어지는 협동적 센서융합을 이용한 화자성별분류를 제안하였다. 센서노드들은 BER(Band Energy Ratio) 기반 음성활동검출을 수행함으로써 불필요한 입력 데이터는 제거하고 관련성이 높은 데이터만을 처리 및 경판정한다. 개별적 센서노드에서 생성된 경판정 값들은 융합센터로 송신되고 전역적 결정 융합을 구축하기 때문에 전력 소모를 줄이고 네크워크 자원을 절약한다. 화자성별분류를 위한 센서융합기법으로써 베이시안(Bayesian) 센서융합 및 전역적 가중결정융합가법들이 제안되었다. 베이시안 센서융합의 경우, 배치되는 센서노드 수 변화에 따른 ROC(Receiver Operating Characteristic) 커브의 동작점을 통해 개별 센서노드 레벨에서 얻어진 경판정 값들을 처리하고 최적의 분류 융합을 결정한다. 전역적 결정을 위한 가중치로써 BER 및 MCL(Mutual Confidence Level)을 채택하여 개별적 지역 경판정 값들을 효율적으로 결합 및 융합시킨다. 센서 노드의 수가 증가함에 따라 분류화 성능이 개선되어졌으며 특히 낮은 SNH(Signal to Noise Ratio) 환경에서 성능 개선폭이 더 높게 나타남을 실험적으로 확인하였다.

In automobile company it is needed to establish the collaborative relationship between the assembly company and the part manufacturing company. In this paper we established the improvement for the procurement logistics and logistics in assembly company and thus we derived the near optimal procurement cycle through the simple EXCEL simulation and the improved inventory management method for H automobile company in CHINA. At this time we adopted the pull manufacturing process instead of push manufacturing process. We resulted that the manufacturing activity of both companies was stabilized and the usage of storage area in assembly company was reduced by 50%, especially it was reduced by 100% in the case of directly delivering the parts to assembly line through the third party logistics company.

This paper is to make strides toward an enriched understanding of the difficulties and issues raised by applying the 7th mathematics curriculum to elementary school classrooms. A general overview of the curriculum is presented in line with teaching and learning methods emphasized in the curriculum. Four classroom episodes are presented in brief in order to diagnose the problems in situating the curriculum in elementary mathematics classrooms. These episodes deal with lessons emphasizing activity rather than its associated concepts or principles, overusing multimedia data, pursuing play rather than its associated thinking, and distributing various individual worksheets in the name of differentiated instructional methods. In addition to the episodes, interview data with elementary school teachers also are presented as needed. This paper discusses two aspects of activating the curriculum into elementary mathematics classrooms. One deals with the issues of the curriculum and textbooks themselves, and the other covers those of research trends on mathematics education and teaching practices. This paper finally emphasizes a collaborative working relation among classroom teachers, mathematics educators, and policy makers with their own places and roles.

Impact of business process re-engineering requires the fundamental rethinking of how information systems are analyzed and designed. It is no longer sufficient to establish a monolithic system for fixed business environments. Information systems must be adaptive in nature. This demand is also applied in production domain. Enabling concept for the adaptive information system is reusability. This paper presents a new object-oriented analysis process for creating such reusable software components in production domain, especially for production planning and scheduling. Our process called MeCOMA is based on three meta-models: physical object meta-model, data object meta-model, and activity object meta-model. After the three meta-models are extended independently for a given production system, they are collaboratively integrated on the basis of integration pattern. The main advantages of MeCOMA are (1) to reduce software development time and (2) to consistently build reusable production software components.
