H5N1鳥インフルエンザウイルスがアジア,ヨーロッパ,そしてアフリカで猛威を振るっている.すでに,100人を越える人が本ウイルスに感染し死亡したが,ヒト‐ヒト間の伝播はまれである.私たちは,人の呼吸細気管支,肺胞細胞の多くが鳥由来インフルエンザウイルスによって認識されるシアリルオリゴ糖(SAα2,3Gal)を発現していることを見出した.しかし,人の上部気道の上皮細胞では,鼻粘膜の一部の細胞をのぞいて,人由来ウイルスによって認識されるSAα2,6Galしか発現していないことがわかった.これらの事実は,なぜ鳥インフルエンザウイルスが鳥類からヒトに直接感染し,感染患者において重篤な下部呼吸器障害を引き起こすことができるかを説明している.また,ヒトの上部気道には,人のウイルスのレセプター(SAα2,6Gal)はたくさん存在するが,トリウイルスのレセプター(SAα2,3Gal)はほとんど存在しないことは,H5N1ウイルスが,めったにヒト‐ヒト間伝播を引き起こさない事実と一致している.しかしながら,H5N1ウイルスの中には人ウイルスのレセプターを認識するものも存在する.したがって,H5N1インフルエンザウイルスが効率よくヒト‐ヒト間で伝播する能力を獲得するためには,レセプター特異性の変化のみならず,それ以外の変異が生じる必要があるのであろう.

The structure of the female local labor market has been studied from the viewpoint of firms or plants as employers, but housewives' role inside their household has not been analyzed. Housewives' working status has not been discussed in detail, on the other hand, at the level of the content of their working activities, using a time-geog-raphical approach. The purpose of this paper is to establish a system composed both of a plant as an employer and of a housewives as employees, and then to understand the female local labor market by coupling dialectically the plant's working and housewives' activities within a time-geographical perspective. The study area-Aonohara district, Tsukui-machi, Kanagawa Prefecture-is situated in the Greater Tokyo fringe area, where a plastic manufacturing plant was newly located and employed female parttimers.It turns out that the plant's action on the inside- and outside-crisis which occured in the above-mentioned system is grouped into two categories: (1) emergency action and (2) radical reform. As a factor of reduction of product efficiency, immediately, the plant and the housewives cope with that crisis through a daily-rhythm. A crisis which cannot be solved through daily-rhythm, in turn, is solved by the monthly-rhythm schedule adjustment. In the case of a crisis which was not solved even by that adjustment, a radical reform has been required through yearly-rhythm. Further a relocation of the plant might be sometimes needed through life-rhythm.

In Europe the study of the history of cartography has a long tradition that dates back to the Renaissance, but its establishment as an independent science had to await the works of L. Bagrow and others since the 1930s. During the ensuing fifty years, a great effort has been devoted to organizing an academic and social framework, including publishing general histories of cartography and facsimiles, and founding the academic society Imago Mundi. During the 1980s, paradigmatic changes occurred in the view and methodology of study in this field. These changes were initiated by P. D. A. Harvey's The History of Topographical Maps and particularly by Concepts in the History of Cartography by M. J. Blakemore and J. B. Harley, both works published in 1980.In this paper the contemporary Anglo-American trends in the study of the history of cartography after 1980 are summarized according to the categories of iconology, context, and social history.1. History of Cartography as IconologyVarious methods of interpreting messages conveyed by means of icons and pictures embedded in maps have been employed in the study of the history of cartography and historical geography. In recent studies of the history of cartography, the analysis of animals (W. George 1978), heraldry (R. V. Tooley 1983), portraits (G. Schilder 1985, P. Barber 1990) and other icons found in maps, as well as of the typology of cartographic symbols and legends (C. Delano Smith 1988), has continued.A synthetic method to consider the map as a whole, not to analyze each element on the map or its border separately, was proposed by Harley (1980 & 1983). He used E. Panofsky's iconology as a framework and suggested that a cartographic parallel existed.Attempts to interpret the whole work as a single icon, semantically or symbolically, have often been limited to the title-page of an atlas, rather than considering the maps themselves. Although Tooley (1975) had published a collection of title-pages of atlases, it was R. W. Shirley (1987 & 1988) who systematically organized all of them. Nevertheless these title-pages are categorized only by their format and content, and there is no in-depth interpretation of any individual map. For instance, the title-page of the Theatrum Orbis Terrarum by A. Ortelius, the first modern atlas, should be seen as a stronger spatial expression of the Darwinian paradigm than of the relation between those dominating and dominated.2. History of Cartography as ContextBeyond the iconographic interpretation, a contextual approach to consider the individual map in the context of the historical circumstances in which it was produced has been developed. The cultural context, or the relationship between the invention of maps in early modern Europe and the corresponding historical and cultural circumstances, especially those of art, has been discussed by R. Rees (1980), S. Y. Egerton (1987) and S. Alpers (1987). All of these credit the impact of the revival of the Ptolemaic grid system to art.In the political and social context, Harley (1983) applied his method to the meaning and function of the various scale maps under the Tudors and developed cartographic semantics. The county maps of Saxton, for example, were prepared with such things in mind as the bureaucracy, defence, local administration and decoration, and they have been interpreted as symbolizing the county community and serving a social function as the identity of the county and as an intellectual discovery of England. Harley (1988) later employed M. Foucault's concept of power-knowledge and episteme to interpret the relationship between the maps and the ideology in them. This work attempted to divide the empty space in maps, interpreted as silence, into intentional and unintentional silence, and to investigate in particular the role of political, religious and social ideology in the unintentional silence.

Ph. F. von Siebold came to Japan to serve as physician at the Dutch Trading Post on Deshima in Nagasaki and, upon his return to Europe in 1828, he attempted to take with him a map of Japan, a prohibited item, that he had received from Kageyasu Takahashi, who was in government service as Tenmonkata. When the map was discovered by the government, the persons involved were apprehended and the map was confiscated. This was the so-called “Siebold Incident.” Siebold, however, had covertly made a copy of the map, which he took with him out of the country. Siebold produced a map based on the map he had brought back and published the map, which depicted the shape of the Japanese archipelago more accurately than those existing in Europe at the time, in Leiden, Holland in 1840.The paper identified this map of Japan which Siebold obtained from Kageyasu Takahashi and used as the original source of the Siebold’s map of Japan. In research to date, the map has been conjectured to be the Kana-gaki Inō Tokubetsu Shōzu( Special Small Inō Map with Kana Notations), which is in the collection of the National Diet Library, though there has been no direct evidence that would actually prove this. For verification, a survey was conducted of map materials in the possession of the von Brandenstein-Zeppelin family, descendants of Siebold who currently reside in Germany.This group of map materials has not been well known in map research thus far. After first providing an introduction, it is pointed out that, as a characteristic, it is comprised primarily of handtraced maps, drafts and such. Due to this characteristic, it was possible to determine from this group of map materials the manner in which Siebold actually carried out tasks involving maps. As a result of the survey, five maps of Japan were found that would appear to have a relationship to the Kanagaki Inō Tokubetsu Shōzu. In particular, through a detailed examination of scale and notation content on two of the maps, items 22 and 26, unique characteristics were identified that are apparent in the Kana-gaki Inō Tokubetsu Shōzu, providing definite proof that they were copied. At the same time, by clarifying, based on new materials relating to the Siebold Incident, the content of testimony given by Kageyasu Takahashi, who was subjected to interrogation for the crime of providing Siebold with the map of Japan, a prohibition item, it was confirmed that the map of Japan at issue is indeed the Kana-gaki Inō Tokubetsu Shōzu.Furthermore, examining the place names and longitude/latitude notations on map item 22, it was verified that the major source is Shoshū Keii (Siebold-collection of Leiden University Library), which is an abridged version of Chisei Teiyō(Outline of the Geography of Japan) edited by Kageyasu Takahashi, in addition to the source provided by A. J. von Krusenstern. Based on the facts mentioned above that the Kana-gaki Inō Tokubetsu Shōzu is a map edited by Kageyasu Takahashi and that the major source of information concerning the place names and longitude/latitude notations is Kageyasu Takahashi, it was clarified that he was not merely a provider of a map of Japan but contributed considerably to Siebold’s map of Japan as the provider of his own unique geographical product.

The purposes of this study were to elicit experiential knowledge from expert baseball pitchers and baseball coaches, to elucidate key coaching points related to movement in baseball pitching, to classify them into categories, and to investigate any commonality among them. Semi-structured interviews were conducted with four former Japanese professional baseball pitchers and seven expert high-performance (national level) Japanese baseball coaches. Each interviewee was requested to comment on the pitching of 25 amateur baseball pitchers (11 junior high school, 8 high school, and 6 collegiate baseball pitchers), which had been videotaped beforehand. The comments were recorded, dictated literally, and divided into segments on the basis of meaning unit. Based on the properties of the various meaning units, some were gathered and classified into categories. For this process, we conducted a member check and triangulation to improve reliability and validity. We extracted 3283 units and classified them into 14 general categories and 71 specific categories. The most frequent category was “trunk open and quick turn during the stride and arm cocking phases”. However, this accounted for only 5.5% of the total meaning units. The next most frequent categories were “weighting on the pivot foot in the balanced position and during the stride phase” (4.7%) and “the throwing arm movement during the stride phase” (4.6%). The contents of all categories covered various aspects of movement. Among the relatively frequent categories, a few elicited the same opinion among the interviewees, but some had different opinions even about the same pitcher. These results suggest that there is a diversity of coaching points among coaches, and that it is important to know the categories that are determinative and those that should be chosen selectively.

The objective of this study is to evaluate an agrivoltaic system by reflecting the deterioration of rice yield and quality. The agrivoltaic system means introducing photovoltaic power to agricultural fields. By the notification from Ministry of Agriculture, introducing renewable energy to agricultural fields became limitedly possible. However, current agrivoltaic pioneers do not always consider crop quality deterioration brought from a total life cycle shading. We evaluate a deterioration of growing in a paddy field in Chiba prefecture in Japan. Heading time delayed significantly under the shading condition. Number of ears and weight per an ear were also significantly less under PV panels. Utilizing measured data, we modified the conventional crop model, which simulates rice yield, quality and economic efficiency under the shading weather condition. A 20 percent shading reduces the yield by approximately 20 percent. Number of ears per root accounts for 84 percent of the yield, which indicates early period of the growth needs enough amount of solar radiation for improving the rice growth.

土木の社会的な印象の悪化に対し,土木業界では「土木」という言葉そのものを避ける事例も見られる.特にそれが顕著なものとして,多くの大学において学科名称から「土木」という言葉がなくなりつつある.しかし,現状では名称の変更が,学科の人気や所属する学生の意識に対してどのような影響を及ぼすのか,実証的な分析は行われておらず,名称変更の是非について建設的な議論ができない状況となっている.そこで本研究では,その影響を明らかにするために,複数の大学の土木系の学科に属する学生に対するアンケート調査,入試データや在学生属性のデータに基づき,学科名称が及ぼす影響を実証的に分析する.分析の結果,土木改名によって,女性比率の向上,建築学科との混同,土木志望度の低下などが生じうることが明らかとなった.

In this letter, we propose and evaluate a new area-based primary protection method for dynamic spectrum access, in which a secondary system uses a frequency band assigned to a primary system while it keeps an aggregate interference below an acceptable level of the primary system. We consider that a location information of a primary system’s reception station (PRS) whose antenna boresight faces towards a moving primary transmission station is ambiguous. To accurately calculate the aggregate interferences from the secondary system to the PRS in such a situation, the proposed method predicts a range of the PRS’s antenna rotation. Our simulation results show that the proposed method can increase availability of the secondary system significantly in a practical urban scenario.

In this letter, we propose a new incumbent protection method that considers three-dimensional (3D) aspects of 5G beamforming characteristics in dynamic spectrum access (DSA). We show some computer simulation results in which fixed wireless access (FWA)-based primary system (PS) and 5G-based secondary system (SS) were assumed to be deployed in a 26 GHz band. The results show that the proposed method can increase allowable transmission power of the SS by considering the 3D beamforming aspects, and that PS and SS height deployment information can additionally bring benefits to the proposed method in terms of the allowable transmission power in DSA.

When solving a mathematical problem, in spite of mastering knowledge and formula necessary for the solution, we sometimes encounter a situation where we cannot reach the correct answer. The reason can be contributed to the lack in metacognitive abilities. Metacognitive abilities consist of comparing the difficulty of problem with own ability, proper plan of solution process, and conscious monitoring and control of solution process. The role and importance of metacognitive ability in mathematical problem solving of permutations and combinations was explored. Participants were required to solve five problems related to permutations and combinations. For each problem, the solution process was divided into (1) recognition of mathematical problem, (2) plan of solution, and (3) execution of solution. Participants were required to rate the anticipation whether they can solve it or not, and to rate the confidence of their own answer. According to the total score of five problems, the participants were categorized into the group of the higher test score and the group of the lower test score. As a result, at the plan and the execution processes, statistically significant differences were detected between the high and low score groups. As for the rating on the anticipation of result and the confidence of own answer, no significant differences were found between both group. Moreover, the relationship between the score of plan process and the score of execution process was statistically correlated. In other words, the more proper the plan process was conducted, the more proper solution the participants reached. In such a way, the importance of metacognitive ability in the solving process, especially the plan ability was suggested.
