携帯電話通信時の位置情報履歴は,全国を網羅的に人々の移動が把握可能であるため,都市交通施策などへの応用が期待されている.都市交通施策のあり方を検討するために国士交通省を始め各自治体で実施されているパーソントリップ調査では,人々の滞在地,滞在時間だけでなく滞在目的も重要な調査項目となるが,滞在目的推定の研究はいまだ不十分である.そこで本稿では,携帯電話通信時の位置情報履歴から,個人の滞在地及び滞在時間を検出し,自宅,職場,お出かけ先などの各滞在地に対する滞在目的を推定する手法を評価する.評価では,利用同意を得た 1250 名の 4 週間の位置情報履歴と行動に関する Web アンケート結果を用いた.Location information associated with communication records of mobile phones has paid attention as a probe for person trips. In this paper, we evaluate a methodology to estimate semantics of significant places extracted from locations associated with communication records. The accuracy of the methodology is demonstrated by experiments using actual communication records of 1250 subjects.

The authors have proposed Vapor Pressure Deficit (VPD) control methods for a solar-light-type plant factory (greenhouse) with a fog-cooling system. In particular, a proportional feedback controller with a variable gain is adopted in an actual system. In the system, however, there is some dead time—was experimentally confirmed by vision-based observation—which brings vibration to the value of VPD. This paper proposes a VPD control considering the dead time of the fog generation by using a communication disturbance observer with a high pass filter (HPF-CDOB). The stability of the whole control system is verified by the small gain theorem. The effectiveness of the proposed control method was demonstrated via experiments. In the experimental result during the high-temperature phase, the proposed method achieves a 81% reduction of the average error and a 20% reduction of the standard deviation in comparison with the conventional method.

This paper is an intermediate report of the clinical observations and various investigations made upon the 16 patients of the radiation sickness caused by BIKINI ashes on. 1st March 1934. The patients were admitted to the First Tokyo National Hospital on March 28th, and this report shall be for the period of the 5 months from March 28th to the end of August, 1964. Later, a thorough and complete report will be given, in which some amendments may be added to the present paper.<br>INTRODUCTION: At 3.50 a. m. on 1st March 1954, the 5th Lucky Dragon, a fishing boat, with a crew of twenty three on board, was located at about 100 miles east of BIKINI. The boat was under grey-white ash-fall for more than 5 hours. The crew was exposed to the ash-fall for 1.5 to 5 hours. The evening of that day they suffered from headache, anorexia, conjunctivitis and later nausea, vomiting, exhaustion and diarrehea, Several days later they suffered from itching, pain, rash, and erosion on the exposed skin areas. One week later two of the crew had hemorrhage of gingiva and some of the crew suffered from depilation. On March 19th, the boat returned to its base at Yaizu. On March 16th, the crew was admitted to the Kyoritsu Yaizu Hospital and on March 28th, 16 patients out of 23 were transfered to our hospital (the First Tokyo National Hospital).<br>On March 26th, Prof. Kimura's laboratory of Tokyo University made the analysis of the ashes taken from the 5th Lucky Dragon and found the following radioactive substances: Sr-89, Sr-90, Y-90, Y-91, Zr-96, Nb-95m, Nb-95, Ru-103, Ru-106, Te-129m, Te-129, Te-132, I-131, I-132, Ba-140, La-140, Ce-141, Ce-144, Pr-143, Pr-194, Nd-147, Pm-147, S-35, Ca-45, U-237, and Pu-239. The remaining radiation of the boat was investigated by Dr. Kakei et al. of March 17th and found it to be around 100mr/hr. Upon this data the total radiation was estimated at a count of 270 to 440γ. on the crew. In addition to the external exposure of such radiation, internal exposure, such as respiration of contaminated air, drinking of contaminated water and taking of contaminated food, shall be taken into consideration in the present cases. Radioactivity was found in the bile and urine taken from the patients.<br>GENERAL REMARKS: The 16 cases were strong young men but their body weight began to decrease from the middle of May and high or slight fever, anorexia, feeling of exhaustion, diarrhea and headache continued.<br>Skin and Hair: Irregular depilation, depigmentation, pigmentation with rain and itching, and erosion was observed. Some cases had folliculitis with pustules in April, while others recovered from erosions and at the end of May, regeneration of hair began. In July, hair condition was almost normal.<br>Blood and Bone-marrow: At the middle of April, the lowest peripheral leucocyte count was less than 2, 000. Two cases who had lower leucocyte count recovered earlier, i. e., their leucocytes increased to around 5, 000 at the middle of May. Meanu hile, the other cases had from 3, 033 to 4.000 count during the entire period. The former cases had also moderate anemia while the latter had only slight anemia. Blood platelet count of the former cases was less than 20, 000 and the recovery was slower than that of the leucocyte count. Reticulocyte count kept pace with that of leucocyte. In the former cases, myelocyte and other immature blood cells appeared temporarily in the circulated blood and eosinophile cells increased. The count of bone-marrow cells decreased remarkably (8, 000), i. e. panmyelophthisis, which later recovered slowly. In the latter cases, peripheral leucocyte findings and myelogram had almost no changes from the beginning of our observation and count of bone marrow cells was remarkably different by the sites of bone-marrow puncture. Vacuole and toxic granula appeared in the neutrophile cells in the circulated blood and vacuoles also appeared in lymphocyte and monocyte.

補助循環中の症例から、連続する2週間に尿中に排泄された必須アミノ酸のトリプトファンの代謝産物のうち、キヌレニン経路からの代謝産物を測定した。比較対照として肝機能指標である総アルブミン、AST、肝臓で産生される腎機能指標BUNおよび炎症性ストレス反応物質であるCRP、プロカルシトニン、尿中コルチゾールを測定した。トリプトファン代謝は肝臓で行われるため、肝機能指標との関係が示された。また、トリプトファン代謝産物の経日的な動態から補助循環回路などに使われる可塑剤の影響が示唆された。更に、肝臓の重要な機能である栄養代謝のうち、エネルギー賦活源であるNADや解糖系への代謝障害が示唆され、栄養学的な観点からも重要な課題と考えられる。また、トリプトファン代謝産物と炎症性ストレス反応物質との間に高い相関係数が得られ、抗ストレス性、炎症反応との関連なども示された。

In this paper, we propose a concept of agile system development which was adapted for the direction of technology evolution. We show the practical use example of a 3D printer and an open source open hardware microcomputer in research education, a class, and an open lecture in National College of Technology, and report on the present situation about education of making things. As a result, it shows that the effect of this concept is high for education at research of the brain functional analysis, research of the environment control and measurement of a plant factory, a class and an open lecture for junior high school students.

1. Research in educational laws and disputation on 'The course of study' After World War II in Japan, a new educational system was founded based on laws focused on the principle of educational freedom. Research in educational laws was undertaken about the new educational system's laws. At that time the Ministry of Education declared that 'the course of study' is a reference book for curriculum organization because of the principle of educational freedom. In 1955, the Ministry of Education disputed that the course of study are legal standards for curriculum organization. But I wrote that the course of study is only a private document by copyright law, and I continued to note that the course of study should be a public announcement by the Government, if the course of study was to have legality for a curriculum organizational standard in my paper of May 1956. The Ministry of Education then legislated the course of study by ministerial order in 1958. 2. Educational war and development of research in educational laws Opposition in the right wing to the left wing in the world, extended to political and educational ideals being in opposition in Japan. The Japan Teachers Union (JTU) as a labor union became left. The late Prof. Seiya Munakata instructors of JTU, his schools and Prof. Masashi Kaneko supplied leftist educational administrational theory to JTU. Kaneko especially contributed to the establishment of jurisprudence. His theory contributed to JTU's educational, labor and political movement, by his theory as 'the order of nature (Natur der Sache) theory' in some of his books. The JTU disputed the administrative actions of the Educational Ministry. These opposing situations have been generally called the 'educational war'. Research in educational laws developed in this educational war takes the position of a theory as legal positivism in my research. Moreover, Munakata and his schools obstructed entablishment of the JEAS for many eyars, but the JEAS was established at last in 1966. 3. Research in lawful educational principles Therefore, is opposition in the order of nature part of theory, especially legal positivism. Why are these two theories the opposite of each other ? These are the basic subjects for research in educational laws. The first subject is the general principle of educational laws. The second subject is the relation of human nature to educational laws. I wrote some books about these subjects. 4. Invitation to research in the principles of educational laws Up to this time, we had research in educational laws by some methods of jurisprudence. Now we should do research in the principles of the educational laws. Then, as a research method should also be a philosophical method and the research is done so that we can get to the fundamentals of educational laws.

We propose a method for vehicle path control that considers sideslip through the combination of a time-state control form and a path control method with nearest point search and we demonstrate the method's effectiveness through experiments with an experimental small four-wheeled vehicle. In the proposed method, combining the time-state control form and path control method with nearest point search for a geometric model that constrains the position of the vehicle in consideration of sideslip allows arbitrary path following through the translational velocity and yaw rate determined from input. The method gives steering angle as input to the yaw rate control system with derived yaw rate taken as a desire value for an equivalent two-wheeled model that considers sideslip. Because cornering power and sideslip angle are difficult to determine in a yaw rate control system, these are estimated using adaptive identification and a state observer, and an adaptive control system is formed. The small four-wheeled vehicle performs path control by use a laser scanner to estimate its position and attitude. The effectiveness of a sideslip angle estimation method that uses motion capture is also demonstrated. We verify that estimates of sideslip angle are nearly identical to measured values, and experiments using a variety of path desired values demonstrate the effectiveness of the proposed path control method.
