The Context of the Development of Peer Programs and Student Learning Assessment in Higher Education in the United States

This study explores of the development process of peer programs and student learning assessment higher education student affairs in the United States. Peer programs are gaining popularity on college campuses. Peer activities began in a resident halls in colonial universities, and organized as resident assistants (RAs) in the 1900’s. And after the 1970s it grew to variety areas in student affairs such as student mentors, student tutors, orientation assistants and peer educators. The student learning and learning outcomes assessment are new challenge for peer programs in the spread of an assessment culture in student affairs. Learning outcomes have become an indispensable element for student assessment cycles. Development learning outcomes on peer programs are achieved through the leadership of professional standards by professional associations. And learning outcomes are characterized by consisting of not only competency as a peer leader like a leadership, community development, communication, but also program management skills. The next tasks of this research are further case studies of peer programs assessment with learning outcomes, for understanding the whole process of a student affairs assessment cycle and holistic student learning outcomes in peer programs. It will be contributory to explore how the shift to a learner-centered higher education through the growing of an assessment culture of student affairs.本研究はJSPS科研費: 30553416 の助成を受けたものである

Research and Design of a Routing Protocol in Large-Scale Wireless Sensor Networks

无线传感器网络，作为全球未来十大技术之一，集成了传感器技术、嵌入式计算技术、分布式信息处理和自组织网技术，可实时感知、采集、处理、传输网络分布区域内的各种信息数据，在军事国防、生物医疗、环境监测、抢险救灾、防恐反恐、危险区域远程控制等领域具有十分广阔的应用前景。 本文研究分析了无线传感器网络的已有路由协议，并针对大规模的无线传感器网络设计了一种树状路由协议，它根据节点地址信息来形成路由，从而简化了复杂繁冗的路由表查找和维护，节省了不必要的开销，提高了路由效率，实现了快速有效的数据传输。 为支持此路由协议本文提出了一种自适应动态地址分配算——ADAR（AdaptiveDynamicAddre...As one of the ten high technologies in the future, wireless sensor network, which is the integration of micro-sensors, embedded computing, modern network and Ad Hoc technologies, can apperceive, collect, process and transmit various information data within the region.
