10 years have passed since the 'Bible'of the prallel distributed processing was published (Rumelhart, McClelland & PDF Research Group, 1986). Throughout the decade, architectures and procedures of connectionist (a.k.a neural nets or parallel distributed processing) models have been growing more and more subtle and complex. The aim of this article is to review some recent connectionist models for three typical research domains of higher cognitive processes (language, analogical inference, and category learning) in detail, and to speculate on their impacts on the coming decade of cognitive psychology and connectionism.

A 5-year-old female cross-breed dog was presented with a 1-month history of progressive changes in the posture of the head and in the gait. At neurological examination the dog showed a central vestibular syndrome lateralized to the left. MRI showed a space occupying lesion within the fourth ventricle, characterized by iso- to hypointensity in T1 and hyperintensity in T2 with a heterogeneous contrast uptake. Histologically, a neoplasia composed of meningothelial cells forming compact whorls with slight atypia, and stellate cells delimitating microcysts containing eosinophilic fluid was observed. Neoplastic cells were positive for vimentin and negative for GFAP and FVIII. A diagnosis of intraventricular microcystic meningioma was achieved. Intraventricular meningiomas in dogs are rarely encountered and reports of meningiomas within the fourth ventricle have not yet been described. Although choroid plexus tumor is the most frequent neoplasia localized in the fourth ventricle, intraventricular meningioma should be included in the differential diagnoses.

The objective of this lecture is to consider the possibility of a new scientific method from the viewpoint of “reality science.” Once, Descartes who presented the method of the modern science wrote A Discourse on Method. However, at present, new reality has become an important theme which could not adequately be grasped by the method he planned. The movement heightens which intends to grasp the reality such as edge of the chaos, fluctuation, noise, complexity, and postmodernity not caught by the method of the science that aims at the recognition of the universal law. In this lecture, I will discuss such new trends from the viewpoint of the “reality science,” and raise a question on the necessity of the method which takes in both of unique factor and universal factor.

As for interpretation of Parietal Art, Magic theory has been the most prominent hypothesis since the begging of 20th Century when the academic research started. Though Magic Theory has been accepted as established motive among the amateurs of prehistoric art, almost specialists have insisted alternative thinking, that is, the interpretation by structuralism. In this paper, the author points out some problems of Magic Theory, for example, signs of arrow, shamanism, devotional image and so on. Above all, the author criticizes the method of ethnographic parallels for its racist base. In any way, the author recognizes theoretical possibilities of Magic Theory, and continues to discuss the problem of integration as basis of Magic Theory.

This paper proposes a contactless vibration testing system for rotating disks based on an impulse response excited by a laser ablation. High power YAG pulse laser is used in this system for producing an ideal impulse force on structural surface without contact. The contactless vibration testing system is composed of a YAG laser, laser Doppler vibrometer and spectrum analyzer. This system makes it possible to measure vibration characteristics of structures under operation, such as vibration measurement of a rotating disk. The effectiveness of this system is confirmed by experimental and theoretical analyses. In this paper, a platter of hard disk drive is employed as an experimental object. Vibration characteristics of a rotating and non-rotating platter are measured and compared with the results of theoretical analysis.

老人保健施設に入所する高齢障害者54名に対して,Visual analog scale(以下VAS)による主観的健康感の調査を行い,幸福感や運動機能,認知機能,意欲との関連性を検討した。結果は,VASによる主観的健康感が高い群の方が,中等度の群に比べてFIM認知機能が低い傾向が認められた。また,PGCモラールスケールとVASによる主観的健康感は弱い相関が認められた。これらの結果から,高齢障害者に対してVASによる主観的健康感を聴取する際には,認知機能の客観的評価とともに解釈する必要性はあるが,幸福感だけではなく健康感を含めることで,より具体的なリハビリテーションの目標設定が可能になるものと推測された。

・本研究は,21世紀を「生命ケア文化再構築の時代」ととらえ,個の自己決定と社会的な相互扶助の両者のバランスがとれた,わが国の文化風土にあったケア文化のあり方を探求してきた。西洋と東洋の死生観の相違がしばしば問題にされるが,それはいずれかが勝っているというのではなく,分析や合理性を重んじる西洋的思考と,総合や直観を重んじる東洋が互いに学びあう必要がある。一方で,文化の差を自覚しつつ,同時に,文化ナショナリズムに陥ることなく,いのちをめぐる諸問題の国際化にも対応していかなければならない。「アジア的」とか「日本的」といった類型化・固定化に陥ることなく,西洋のケア文化の歴史的深みと現代的展開の意味も十分に理解しなければならない。21世紀の生命ケア文化再構築は,グローバル化のなかで,比較文化論的視点に立った柔軟な発想で進めていく必要がある。以上のような研究成果を,国際シンポジウムを開催するなど,国際的に開かれた討議空間のなかで検証してきた。・臨床学的アプローチのなかでは,<施設から在宅へ>が後戻りできない流れであり,それを支えるコミュニティ・ケアとスピリチュアル・ケアが極めて重要となってきていることが明確になった。・21世紀ケア文化を担う新しい世代に対しては,「いのちの大切さ」を漠然と教えるのではなく,いのちが向かう先にある<いのちの美しさ>を芸術作品などを通して感得しこの世に在ることへの大きな信頼を取り戻し生きる力を高めるような生命ケア教育が必要である。例えば理科教育のなかでも,自然の奥深い構造を示すとともに,それらについての科学的知見と技術的応用が社会にもたらす影響についても具体例に即して考える教育プログラムと授業展開が必要であろう。以上のような成果を研究成果報告書,ホームページや著書,公開講座,授業展開などの形で発信してきた。

Large capacity tags are becoming available to meet the demands of industry, but the UHF RFID protocol is unable to reliably and efficiently read large data sets from tags. First of all, large data sets are not well protected. The tag merely relies on 16-bit CRC for ensuring the validity of up to 4,096-bit user-specific data in EPCglobal C1G2 protocol. Furthermore, the reliability will be even worse if large capacity tags are implemented using semi-active technology which is likely to prevail among sensor-integrated RFID tags. Since semi-active tags greatly alleviate the performance limitation imposed by the turn-on power of the tag chip, backscattering signal of semi-active tags could be a serious challenge for most readers because it is much weaker than signals emitted by passive tags due to longer reading distance. In this paper, Interim CRC is presented to enhance transmission reliability and efficiency when the tag is backscattering a large data set. By taking advantage of Interim CRC, the large data set can be divided into several blocks, and 16-bit checksum is calculated over each block. The tag backscatters all blocks at the first time and only retransmits certain blocks if CRC error occurs in those blocks. The result of simulation shows that the reading error rate can be confined to a preset threshold and the accumulative total of transmitted data are greatly reduced if optimal block size and transmission times are complied with. The simulation also conclusively proves that semi-active tags derive even longer reading range from Interim CRC. In addition, Interim CRC is totally compliant with the EPCglobal C1G2 protocol. It fully makes use of CRC-16 encoder and does not involve any other data encoding schematics and hardware modifications.

This paper presents a new generalized single threshold model that can be used in communications and cellular networks. In the proposed model, called Single Hysteresis Model (SHM), it is assumed that the amount of resources accessible for a new call of a given class can depend on two load areas of the system. The switching between areas is modulated by the two-state Markov chain which determines the average time the system spends in a particular load area, i.e. the area in which calls of selected classes with a reduced amount of resources (high load area) and with the initial amount of resources (low load area) are serviced. The results obtained for the discussed analytical model are compared with the results of the simulation of an exemplary WCDMA radio interface carrying a mixture of different multi-rate traffic streams. The research study confirms high accuracy of the proposed model.
