By the development of the computer in recent years, calculating a complex advanced processing at high speed has become possible. Moreover, a lot of linguistic knowledge is used in the natural language processing (NLP) system for improving the system. Therefore, the necessity of co-occurrence word information in the natural language processing system increases further and various researches using co-occurrence word information are done. Moreover, in the natural language processing, dictionary is necessary and indispensable because the ability of the entire system is controlled by the amount and the quality of the dictionary. In this paper, the importance of co-occurrence word information in the natural language processing system was described. The classification technique of the co-occurrence word (receiving word) and the co-occurrence frequency was described and the classified group was expressed hierarchically. Moreover, this paper proposes a technique for an automatic construction system and a complete thesaurus. Experimental test operation of this system and effectiveness of the proposal technique is verified.  相似文献

A comparative study on the photosynthetic parameters among intergeneric progenies derived fromOryza sativa L.×Sorghum vulgare L., its maternal parent Gui 630 and commercial 3-line hybrid rice Shanyou 63 in pot experiment in greenhouse was conducted. The morphological and photosynthetic characters of canopy leaves and chlorophyll fluorescence kinetic parameters includingF v/F m,F v/F 0, photochemical quenching coefficient and non-photochemical coefficient of canopy leaves of 3 varieties were measured. The results showed the progeny, Yanyou 1, derived from an intergeneric cross of rice and sorghum possesses better canopy spatial architecture with thicker, heavier and bigger canopy leaf than its maternal parent Gui 630. Higher photosynthetic rate due to higher chlorophyll content, higher primary energy transformation efficiency, potential of PSII and non-photochemical quenching coefficient (q E) were also measured in Yuanyou 1. These explain partly why the intergeneric progeny has higher biomass production, and better tolerance to adverse conditions and higher field yields even under stress conditions.  相似文献

In this article, we address the choice of suitable instructional units that might serve as the basis for cross-cultural analyses of classroom practice. Our argument draws on analyses undertaken as part of the Learner's Perspective Study (LPS). The database comprised a three-camera video record of sequences of 10 consecutive lessons in each classroom, supplemented by post-lesson video-stimulated interviews with teachers and students: a total of over 180 videotaped lessons, over 50 teacher interviews and almost 400 student interviews. The results of these analyses challenge the suitability of the lesson as the unit of comparative analysis. In particular, the location of the lesson in the topic sequence is seen to be a key influence on the lesson's structure, critically affecting the teacher's deployment of the constituent activities that we have called ‘lesson events.’ The lesson event is proposed as an alternative unit of international comparative analysis of classroom practice.  相似文献

The recent restructuring of higher education in Japan has been carried out in the context of neo‐liberalism with an emphasis on the unbridled workings of market forces. However, civic discourse on issues such as active citizenship and social inclusion/exclusion, which is significant to higher education as a democratic public sphere, has been left behind. Focusing on this omission, this article aims at a critical analysis of the government expansion policy initiative in Japan. It includes discussion of a wide‐ranging group of participants, in particular adults who are disadvantaged with regard to access to higher education in a knowledge‐based society, from the point of view of lifelong learning. It is a very important subject in Japan to encourage the active participation of adults in higher education. Regarding this aspect, the article discusses significant points for building new concepts and systems in higher education, instead of the established traditional concepts and systems, which have contributed to the exclusion of adults from higher education.  相似文献

The morphological and photosynthetic characters of canopy leaves and chlorophyll fluorescence kinetic parameters including Fv/Fm, Fv/F0, photochemical quenching coefficient and non-photochemical coefficient of canopy leaves of 3 varieties were measured. The results showed the progeny, Yuanyou 1, derived from an intergeneric cross of rice and sorghum possesses better canopy spatial architecture with thicker, heavier and bigger canopy leaf than its maternal parent Gui 630.

Since the first Modern Olympics in 1896 only a few cities have hosted or will host the Summer Olympic and Paralympic Games more than once: London, Paris, Los Angeles, Athens and Tokyo. There is no doubt that the improvements in infrastructures and structural changes that were carried out for Tokyo in preparation for the 1964 Tokyo Olympics demonstrated that ‘Japan was experiencing remarkable economic growth’. The ‘development’ of Tokyo, 97% of the Olympic budget being earmarked for improvements to infrastructures, resulted in excessively centralised politics and economics. Looking at the bidding process to host the 2016 and 2020 Olympics, it can be seen that various expectations of sports are political in nature: from the political problem of remembering legacies as mere representations to the current situation of a nation basing its presence on involvement in the Olympics. The Sports Promotion Act enacted in 1961 was revised 50 years later, and policies on sport came to be regarded as national strategies. The new act became the basis for establishing the Sports Agency and specified governmental support for hosting the international sporting events it promotes. The time has come to seriously consider the necessity of critically arguing about nationalism, as well as how to determine the relationship between a nation and sport in terms of sport governance.  相似文献

The B-matrix method, which systematically analyses the dynamic response of non-symmetric rigid bodies, such as golf putters, is described. The three-dimensional translational and rotational accelerations of the putter face are represented by linear equations of input forces and moments represented in matrix form. The elements of the 6 × 6 B-matrix physically represent the acceleration intensity factors. This method is applied to the analysis of the putter face control mechanism. The input forces and moments are obtained by the inverse dynamics method, whilst special attention is paid to the putter face rotation, i.e. the angular acceleration around the axis of the shaft, $ \dot{w}_{ox} . $ The contribution of input forces and moments on $ \dot{w}_{ox} $ is discussed quantitatively. The results demonstrate that $ \dot{w}_{ox} $ is present even if the input force and moment are applied perpendicularly to the shaft. A cancelling mechanism to correct this motion is discussed based on the B-matrix method.  相似文献

In Japan the use of the term lifelong education has become widespread throughout the 1990s and is central to educational policies, which actively tackle crucial subjects that take place in a wide area of education in a drastically changing contemporary society. This paper examines in detail the present situation of the development of lifelong education, in particular concerning adults, relating to the traditional ideas and systems on education called a highly school-centred society. These traditional ideas and systems, even today in Japan, have still functioned to greatly value school credentials and disturb the widening of the participation of adults in lifelong education, nevertheless adults have stood in need of continuously studying up-to-date knowledge and skills in a wide range of areas and at a different level throughout their working lives.  相似文献
