CanSat is a fake artificial satellite to learn a coordinated operation with various subsystems which makes up an integrated satellite system. In order to apply the CanSat to an actual curriculum to be invoked at Tokuyama College in 2017, a prototype CanSat is developed in 2016. The CanSat has basic bus systems including, power, structure, communication, thermal control, attitude control and data handling systems. In this paper, we introduce the basic function of this CanSat and discuss the prospective application to the actual engineering design education.

It has been said that the Roh-Haiden in the Yamaguchi Prefecture is rare across Japan. There are 11 Roh-Haidens in Shunan City, according to Yamaguchiken-Jinja-Shi, but about half have not been studied. Therefore, this study aimed to clarify the characteristics of all Roh-Haidens in Shunan City. At first, we measured these Roh-Haidens and made their plans; at the same time, we took their photos. We investigated their characteristics using their plans, photos, and old books. The results of this study are the following: most are located in Mae-Yamashiro-Saiban, and it is estimated that this style was established in the latter half of the 19th century in this region. The size and the structure types of the Roh-Haidens are related.

In this paper we describe how we enabled the standard C language functions in the educational system description language C--. Because of the flexible description ability, the C language is popular in the embedded system developers. But, it is difficult for students to master C language in a short time. So, we defined C-- language for the student. It is easy to master the C-- language that has no difficult C language syntax. And we developed the translator to use C-- with many computer systems. However, it was difficult to use the standard C functions in C-- because they used the types that depended on them. Therefore we introduced new syntax to define a type easily.

A growth monitoring in horticulture has become an important technology for an efficiency of agricultural work, a quality improvement and a safety of an agricultural products. Recently, in order to achieve environmental monitoring efficiently corresponding to a scale of a greenhouse, sensor network technology using a network communication has become a major technique. In this study, we propose a sensor network system which is suitable for the management and operation of a local heating stainless steel foil tape heater in the efficient growing of the strawberries. The system is constructed by a gateway used the Linux-OS based Raspberry Pi computer, and small sized sensor modules which include a ZigBee wireless device.

It is important for students of computer science cource at the universities to understand the operation principle of the computer systems. In order to understand them, it is preferable to perform practical learning with the system that actually works. So we developed an educational computer of simple hardware configuration called TaC. In this paper, we describe a method for operating the language processor on the small main memory of TaC. We divided the compiler into six modules. Thereby, we describe a reduction method for main memory size consuming at a compile module-divided. Object size of each module is expected to be within 15 kiB.

The layer structured vanadate of Rb_3V_5O_<14> has been prepared using Rb_2CO_3 and V_2O_5 at 500℃. The ion exchange reactions of rubidium ion (Rb^+) in the interlayer space with sodium ion (Na^+), hydrogen ion (H^+) or lithium ion (Li^+) were studied in aqueous solutions. The sodium ion (Na^+) exchange product of Na_<2.00>H_<0.92>Rb_<0.08>V_5O_<14>・3.5H_2O was obtained. The host layers were retained on this ion exchange reaction. In contrast, any of ion exchange product of H^+ or Li^+ was not obtained. The reaction products were characterized by atomic absorption or flame analysis, TG-DTA and XRD.

In this paper, I propose a learning-support system for Java programming language. In order to develop the learning-support system, I carried out a questionnaire survey to students. Based on the result of survey, it became clear that it was difficult for students to install software and set environment variable. To avoid these difficulties, a learning-support system is required for programming education.
