We describe the life-work of Father of Japanese Chemistry “Udagawa Yoan”. Udagawa Yoan was influenced by his adoptive father Genshin’s philosophy and by doctor and botanist Ito Keisuke’s publication Nijyushi Kokai (Explanation of Twenty-four classes). In 1834, he published three volumes of “Shokugaku Keigen (Principles of Botany)”. They show history of the translation of basic botanical terminology and for natural philosophy and experimental plant physiology. His “Shokubutsu Shasei Zufu” demonstrates a talent as botanical artist. Moreover, on his interest in pharmacy and botany, he found some relations to chemistry. Continuously, he published his first chemistry textbook “Seimi Kaiso” based on a Dutch translation of William Henry’s chemical book. “Seimi” comes from pronunciation of “Chemie” in Dutch and “Kaiso” means “Opening of Chemistry”. He had to develop new terminology to describe chemical substances and processes, expanding the Japanese vocabulary of chemistry. His first interest in chemistry was its application to the practical arts with glassmaking. “Seimi Kaiso” for volume 3 describes the beginner’s manual on the chemistry of “biidoro”.

Since the tourism is one of the main industry in the Southern Hokkaido area, the decrease of the number of tourists is the problem that needs to be solved. Since there are many attractive leisure activities in the Southern Hokkaido area, we propose the novel advertising method of the leisure activities of the Southern Hokkaido area. The purpose of this study is to develop a system which provides the simulated leisure activities to future tourists. In this paper, a remote fishing machine to provide a fishing simulation on ice is proposed as one of the winter leisure activity. The remote fishing machine consists of a controller rod and a fishing rod. In this system, a user operates the controller rod. And, then, the fishing rod is moved to follow the behavior of the controller rod. All behaviors of the developed system were desirable and the system makes it possible to catch fishes by user. Experimental results show that this system can let user experience pleasure of the fishing.

Glass beads, possibly belonging to Ainu Culture, were analyzed by XRF technique to understand the origin of these glass. The samples were excavated from Hokkaido belonging to the periods from the mid 14th to the 19th century AD. The analytical results showed that the beads can be classified into two types, lead-potash silicate glass and potash lime silica glass, based on the major components. The proportion of the potash lime silica glass in total glass analyzed is significantly higher than that usually found in beads excavated in Honshu area indicating an apparent difference in the source of the glass. A compositional similarity was observed in green potash lead silica glass between present samples and Ichijyodani Asakura Clan Ruins(15,16th century AD). Potash lime silica glass beads were classified into two groups based on trace heavy elements compositions, indicating the presence of two origins.

This paper reports the result of the chemical analysis of the Chinese coin Yongle Tongbao owned by Khabarovsk Regional Museum named after N.I. Grodekov. It was found that this Yongle Tongbao is the officially minted coin. This coin was excavated in Krasnokurovka burial ground in the Khabarovsk Territory. The burial ground was made under the Pokrovka culture (from the 9 th to the 13 th centuries). However the Yongle Tongbao, which was first minted in 1408, was discovered in the mound No. 30 of Krasnokurovka burial ground. So, it is necessary to reconsider the end period of the Pokrovka culture.

Several types of systems for disaster communications and networks have been studied to comprehend damage situations immediately in a heavy disaster. We have, however, been confronted with difficult issues to deploy the system actually in society, and it has not been raveled yet. To promote deployment of such a disaster resilience system, we have carried out an experimental study in the project-based learning program (PBL) of National Institute of Technology, Hakodate College (HNCT). Examining wireless mesh-networks called NerveNet, which was developed by the National Institute of Information and Communications Technology (NICT), we set up the wireless networks experimentally in HNCT. Reviewing the requirements of local governments on disaster damage assessment, we propose an impetus model to deploy the disaster system in society by exploiting a regular educational program, PBL. This paper shows a testbed of wireless mesh-networks, which is configured with NerveNet and implementing required functions in web application forms.

We conducted ground penetrating radar survey on the Chashi Sites of Shibecharigawa basin of Shinhidaka in Hokkaido, with the purpose of investigating the internal structure of the Chashi. The surveyed sites were Shibechari-Chashi and Hoinashiri-Chashi. Shibechari-Chashi was thought to be the fort of Shakushain, leader of Hidaka Ainu. There was the anomaly likely to be a ditch around Chashi. In the case that it was a buried ditch, Shibechari-Chashi would come to have the largest area in Hokkaido. In Hoinashiri-Chashi, the reflection related to the chashi was gained at the main/center part of the site. Also, the anomaly detected on the west side was thought to be the reaction of the buried ditch. These results showed the Chashi was surrounded with the ditch and strengthened its protection.

In the analysis, to study a function, we often representing the function as a series like a Taylor series and Fourier series. Fourier series can be regarded as a representation by components on some sort of orthonormal system in function space. In this paper, we introduce the function space with the metric that is suitable for the Taylor series.

Natsume Soseki wrote "Travel Notes of Manchuria and Korea" in 1910. In this work has several phrases which are considered by some to be discriminatory examples being; such as "There are a lot of Chinese Coolies here. Looking at one Coolie makes me feel dirty, and looking at two Coolies makes me feel repulsed." With regard to such expressions, some Japanese researchers defend Soseki, but other researchers from former colonies have a critical attitude toward them. For example, one Japanese researcher, Tatsuo Aoyagi has said that we should not apply our present sense of human rights to Soseki's expressions in that work. He does not think that such phrases indicate that Soseki has a sense of discrimination. On the other hand, a Korean researcher Pak Yunhe and a Chinese researcher Wang Cheng insist that Soseki is discriminatory. However, an American researcher Joshua A.Fogel who has no direct relation with the colonial situation thinks that it is meaningless to consider whether Soseki had a good feeling or antipathy towards China. While taking their arguments into account, in this paper, the author discusses Soseki's so-called discriminatory expressions in his "Travel Notes of Manchuria and Korea", and presents the idea that the writing style, that is the Shaseibun-style may be cause of this discriminatory impression.

A lot of structures, such as a bridge, a tunnel, an expressway and a steel tower, which give the damage to the society by the destruction exist in this country. The safety inspection of the bolt used for those joining part is the work on which a lot of time is spent and is high-cost. The sensor which could easily visualize a destruction risk was developed by this study. The sensor consists of the first material, the second material and spring. The second material is installed for the first material in parallel, and one end is fixed. The second material has a fragile characteristic than the first material, under the elastic deformation or plastic deformation. When a joining part is deformed by external force, the first material also is deformed. Then, the second material breaks and jumps out by the spring force to outside. Therefore the destruction risk of the junction can be visualized. The destruction detection system was developed by converting an electrical signal by a switch with the signal that the second material protruded. The break of the second materials was able to be confirmed as electrical signal by a simple experiment.

Production of lead silicate glass declined by 9th AD in Japan. Instead lead potash silicate glass (K2O-PbO-SiO2), a new compositional type of glass, flowed into Japan from China. Then lead potash silicate glass become a major glass type in the medieval period of Japan. Especially in Hokkaido, glass beads were favored by Ainu culture. So we focus on the circulation of glass in Hokkaido at the Ainu cultural period to understand the glass trade in relation with glass in Honshu. In this study, we analyzed glass beads excavated from sites in southern Hokkaido, which were important bases located between Honshu and central Hokkaido. The samples are excavated from archaeological sites at the periods from the 15th~19th century AD. The analytical results showed that these glass beads can be classified into two types – lead potash silicate glass (K2O-PbO-SiO2) and potash lime silicate glass (K2O-CaO-SiO2). These types of glass are also major types distributed in Hokkaido at the period of Ainu culture. In addition, we have found the presence of a large number of purple glass beads made of lead potash silicate glass utilizing antimony oxide as emulsifier. Interestingly, they are only characteristic to southern part of Hokkaido.

The potteries were produced in various sites of southern Sakhalin region and the northern and eastern Hokkaido. These sites belonged to the Jomon culture, the Epi-jomon culture and the Susuya period of Okhotsk colture. The potteries were made by mixing sands in clay and the chemical composition of mixed sands contain geological information of the region where potteries were made. The chemical analysis of soil of potteries can estimate the product sites location. This technique can help clarify the product sites of each potteries and the route of delivery of the potteries.

In this study, chemical compositions were reexamined on the glass beads excavated from the Usu-Oyakotsu site in Date City, Hokkaido. As a result, it was possible to clarify that these glass beads are composed of potash lime glass and potash lead glass. In particular, it is noteworthy that the majority was potash lime glass. In addition, it became clear that the potash lime glass is divided into two compositional types, lead - containing type and lead - free type. Especially for lead - containing type, it might be one of the features of potash lime glass distributed in the early Ainu culture period.

As the world becomes increasingly globalized, the situations in which people need to use English in communication will increase. Thus, concerns over TOEIC scores have risen. Therefore, TOEIC special lectures for voluntary participants of all grades have been conducted at National Institute of Technology, Hakodate College for two years. This paper reports on the effects of the lectures based on the scores and the number of examinees in TOEIC IP. As a result, the score of the participants in these lectures were increased significantly. In addition, the number of examinees were increased more than three times. Therefore, conducting these lectures has resulted in a good effect on the score of participants and the number of examinees. However, the average score of the TOEIC IP was decreased. Considering these results, it can be presumed that these lectures had an effect on the limited students. Moreover, these results suggest that increasing average score as a school is needed.

This study was to propose a replaceable event at night with low visibility on the observation deck of Mt. Hakodate. Two possibilities were studied. The first was to project a picture of night view on cloud. To check this possibility, flow distribution around Mt. Hakodate was studied by numerical simulation and water tunnel experiment. The result showed a very low possibility. The other was to project a picture such as night view on a water-sprayed screen. This experiment indicated that the screen has another utility besides as a part of fire prevention system.

Recently, to reduce the inconvenience caused by authentication operations in portable terminals such as smartphones, various authentication methods based on behavior characteristics have been studied. We proposed authentication method which identified individuals based on walking motions measured by wearable sensors such as acceleration sensors, and can be implemented on a smartphone (as smartphones are equipped with sensors). In the many case of multimodal biometrics authentication with machine learning, the common classifier for all users is generated. One of the reasons for this is that these authentication systems are installed into the equipment shared by users, such as the server computer. This server computer identifies the all authorized persons and the non-authorized persons. However, each smartphone is occupied by each user and is not shared by the multiple users. Therefore, the classifier to each user for fusing the features can be generated for each user in their smartphones. The purpose of this paper is to reveal the influence by generating the individual classifier for each user and a common classifier for all users. We evaluated the authentication accuracy by employing both the classifiers generation methods.

Since 2000, we have attempted to improve a method of leading and experimental theme in the fundamentals of electrical and electronic engineering laboratory I accompanying with a reorganization from dept. of electrical eng. to dept. of electrical and electronic Eng.. In the second-year class, instructions of how to write a technical report were also included into contents of the electrical and electronic experiment. In the present report, we investigated such a method of leading, the experimental system and other problems based on previous enquetes. As a result, it was judging that current experimental system: members of groups, volume of contents, were adequate for students. Additionally, the instruction of technical report was meaningful for the students and we could confirm the necessity of continuing the efforts. On the other hand, some problems: 1) student's preparations to experiments are not sufficient 2) students frequently depend on teacher's advices 3) teachers are not enough to explain evaluation system to students 4) whether experimental themes are really proper or not, were revealed. These examinations and improvements should be needed continuously in the future.
