The paper introduces a processing of the images of the baceball scoer book. Rules of the baseball look simple; pitching, catching, hitting, running, etc. However it is very complicated game in fact. Recording a game is done by writting a score book. It needs high skills for accurate records. Therefore undestanding the game from the written score book is also difficult. We started the analysis of the score book to get the average of each batter.

There are two characteristic areas in the coastal waters of Osaki-Kamijima where marine plants and algae grow. One is the area where they grow naturally such as around Ikuno-shima Island and the other is brackish area such as around the drain outlets of a thermal power plant, which are widely known among local fi shermen. The growing area is diff erent by species, and it is easily supposed that there is best suited environment for each species.
In this study, the authors collected data regarding growing factor of Eelgrass around Osaki-Kamijima, extracted infl uential factors, and report some fi ndings obtained.

The authors developes an experience learning program on marine issues for the primary and junior high school students who only have limited opportunity to take marine-related lessons. In this paper, how to program worked and the qestionnaire result after the lesson are reported.
The program consists for a marine-related experience learning to observe Eelgrass that improves the marine enviroment. it was found that the students who joined the lesson showed increasing interest in marine isuues through the observation of local sea.

In the coastal sea area in Japan, red tide generated in every summer is one of the causes of fishery serious damage.This is important society and economic progblem. The authors have have studied studying about the red tide observation system to prevent damage suffered from red tide. The authors have developed the system using observation buoys and wireless communications for monitoring system. This system can observe the position and seawater temperation in real-time when red tide occurs. In this paper, we describe tha basic constitution of the developed observation system, and expriment results.

In this paper, we describe a novel energy monitoring system with wireless sensor modules.The objective of our research was to calculate the power consumption in a number of rooms to store and display the measured date on personal computers. For measuring the data, we used wireless sensor modules each consisting of Arduino with XBee. This monitoring system can monitor the swiching of ceiling lights and calculate the power consumpition in each room.

This paper reports the problem of avoidance of science and technology leaning is one of the big issues for education in Japan. Part of the problem might arise from the lack of so called "monozukuri " or engineering design activities at elememtary svhool levels. hands on class room activities for elementry schools are developed including the followings. The educational results of this approach are discussed in the context of student questionnaires.

This report shows how we have carried out the programs to promote the Japanese studentsʼ crosscultural
understanding, which includes two sides: i) realizing another way of thinking when the students come to our college from the Philippines, and ii) explaining their own culture when the Japanese students try to talk about it in Manila. The procedures in the lessons are introduced and examined, while leaving fundamental issues.

Our school has tried in many ways to rebuild a new style of dormitory management and prevention of
irregular behaviors in residents for many years. Such irregularities as smoking, garbage-throwing away, stealing, late-night hovering, or breaking facilities, are too persistent to get rid of easily. In addition, recently the number of residents has been on the sudden increase and very close to the capacity, which leads us to face the need to refit the existing building and build a new one. As their number and residential space are becoming much larger, our turns to stay at night in dormitory are augmenting to the extent that the teachers come to fi nd the task at dormitory so heavy. This paper is to tell what our school has done for these four years to improve such a
situation as mentioned below. As a result, the construction of some systems to prevent irregular behaviors and the new framework of night watch, the cooperative work with Parents Association are presented here as a new basement of our school dormitory management.

With the introduction of Class B AIS, the circumstance is being ready to install AISs on board of small boats under 500 tons. However in reality, these Class B AISs are not installed aboard small FRP boats under 5 tons. In these circumstances, radar plays an important part to keep track of these boats, other than visual identifi cation. Although the axial and lateral resolution of the radar aboard the own ship is one of the indicators for the separate display in general, the range in which the echoes of small FRP boats would be distributed on the PPI display is not always clear in relation to the radar receiving sensitivity. Accordingly, the authors developed a system for sampling the radar echo signals in high frequencies by A/D conversion of the receiving signals. Using this system, we analyzed the two-dimensional distribution of radar echoes and report the result.

The toxic eff ects of lead are well known thus reducing lead in solders is important for the environment
and the human health. Using the lead-free solders are being required to electronic devices on ships.
NISHISHIBA ELECTRIC CO., LTD. and the members of Hiroshima-maru examined the Auto Voltage
Regulator (AVR) with lead-free solder on Hiroshima-maru. The defects on the AVR caused from the shipʼs vibration and temperature were not found out in these examinations.
