This study was conducted to collect basic data for establishing a revitalization plan for agricultural machinery departments in technical high schools. A status survey on satisfaction and career plan of students majoring in agricultural machinery in technical highschool was measured. The survey results showed that the selection motivation for technical high school was mainly due to the academic score obtained during middle school, and an academic major for agricultural machinery was mainly based on personal interest and aptitude. About 90% of the students answered as "normal" or "satisfied" to the questions asking satisfaction level for agricultural machinery major and education. For career plan, 68.5% of the students answered as "entrance into academic schools for higher level education" and 31.5% answered as "employment". Most preferred higher level education area was "engineering" (30.8%) and "agricultural machinery" was only 12.6%. Expecting employment area was also automobile or other industrial machinery rather than agricultural machinery.

Inventory survey is process collecting data about cut slope. It's different from inspection. It contains not only basic information about cut slope, especially location, GPS positioning, height, length, weathering, joint direction, water conditions but also level of danger and damage. Collected data are being used get at status about cut slope along national roads. And It helps judging about priority of detailed investigation. According to results of analysis, we found better method about maintenance of cut slope. Later on, if inventory research is finished, we will understand characteristics of collapse slopes.

Technical standards is directives for managing telecommunication network and also designing objectives for telecommunication network. The scope of technical standards varies from network environment of each countries but most countries compelled to observe the specified matters in technical standards. Generally, technical standards are the items extracted from national standards that must be followed by network providers. Technical standards is so very important to consist user's right and network operation that it is usually handled by national levels. In this paper, we analyze current status of technical standards for other countries and suggest some expected directions of technical standards schemes for domestic network.

While applying the systems engineering (SE) in systems development, a series of technical reviews play a critical role and is intended to monitor the status of the progress and outcomes of the project for which appropriate technical plans prepared earlier should be executed. It is noted however that during the technical review executed as planned, a lot of problems usually come out. Included are the ambiguity in the reports of the progress status and outcomes, discrepancies among the opinions from different participants, and the delay in carrying out the tasks. To solve those problems in an early stage, informal reviews are usually adopted before the formal technical reviews are held. A type of the informal reviews is the peer review. This paper is concerned with the peer review process model to make the later technical reviews more effective. Specifically, we first review the necessity and meaning of the peer reviews. We then study a model for the peer review process. To model the process, the methods of an IDEF modeling and schema definition have been applied using a computer-aided SE tool, Cradle(R), in the environment of the national research and development project. As a result, the implemented process model can show hew the peer review process is designed and managed to be utilized in the technical review. The documents related with the peer review process can also be generated automatically from the developed model Database. Finally, a general misunderstanding about the peer review and its improvement plan have also been mentioned.

The current status of the development of pyrostarters, which play a role as a turbo pump starter in liquid propellant propulsion systems by supplying pressurized gas to power turbines for engine start, has been introduced. Firstly, the development history is briefly summarized, and secondly the current technical status in core parts for the development of pryrostarters such as solid propellants, internal ballistics, rupture discs, and igniters are presented. The current technical achievements could make it feasible to fulfill the development requirements for pyrostarters.
