The purpose of this study was to develop the Japanese Defensive Pessimism Inventory (JDPI), which measures defensive pessimism in an academic achievement situation for Japanese undergraduate students and differentiates between those who are realistically pessimistic and those who are defensively pessimistic. In Study 1, 695 undergraduates completed the JDPI. A factor analysis revealed that the 24 items of the JDPI comprised four factors: Pessimism, Past experience, Positive reflectivity, and Effort. In Study 2, 618 undergraduates completed the JDPI, the Test Coping Strategy Scale, and the State-Trait Anxiety Inventory. The JDPI had high internal consistency and test-retest reliability. Defensive pessimists and strategic optimists had higher scores on the active coping strategy and lower scores on the avoidant-thinking coping strategy than did realistic pessimists. Furthermore, defensive pessimists and realistic pessimists had higher scores on the state anxiety and lower scores on the optimistic-thinking coping strategy than did strategic optimists. The results indicate that the JDPI had high concurrent validity.

放射線不透過マーカーを用いて大腸通過時間を測定し,便秘の質的診断を試みた.健常成人ボランティア43名を対象とし,1,2,3日目に放射線不透過マーカー(Sitzmarks)を服用,4,7日目に腹部単純写真を撮影,Metcalfらの方法で全大腸通過時間,大腸各区域(右側,左側,S状結腸直腸)通過時間を測定した.質問アンケートと排便状況(回数,ブリストルスケール)について自記させた.通過時間は中央値で示した.男性(n=13)はすべて便秘(-)で,全大腸通過時間は7.2h,右側2.4h,左側3.6h,S状結腸直腸2.4h.女性で便秘(-)(n=24)は全大腸31.8h,右側4.2h,左側9.0h,S状結腸直腸11.4h.女性で便秘(+)(n=6)は全大腸110.4h,右側30.6h,左側36.6h,S状結腸直腸30.0hであった.大腸通過時間が40h超の延長例を類型化すると,左側通過時間を最長とするcolonic inertia型とS状結腸直腸通過時間を最長とするoutlet obstruction型に分類できた.この分類は排便回数やブリストルスケールでは判別できず,放射線不透過マーカーによる質的診断の有効性が示唆された.

Pemphigus foliaceus (PF) is an autoimmune blistering skin disease that affects certain mammals including dogs. In canine PF, neutrophils are infiltrated intensely into pustular lesions including acantholytic cells, although neutrophilic infiltration is not characterized in human PF. The roles of the neutrophils in the cutaneous lesions of canine PF have not yet been understood. The purpose of this study was to characterize the ultrastructural features underlying the acantholysis with pustule formation in canine PF. Four dogs diagnosed as PF on the basis of clinical signs, histopathological findings, and direct and indirect immunofluorescence examinations were performed. Electron microscopy revealed that the acantholytic cells were adjacent to multiple neutrophils in the pustules. At the contact points between neutrophils and acantholytic keratinocytes, half-desmosomes of acantholytic keratinocytes with intact attachment plaques were observed within invaginations of neutrophils. Furthermore, on the surface of acantholytic cells in the pustules, neutrophil granules seemed to be secreted to the surface of acantholytic cells and to degenerate the half-desmosome structures. Neutrophils were also observed within the epidermis adjacent to the pustule. At the intercellular gap between two dissociated keratinocytes, neutrophils inserted its pseudopodia into the gap between the two half-desmosomes of keratinocytes. These findings taken together suggested that, at least in the areas where we analyzed ultrastructurally, neutrophils contact desmosomal structures and seem to play some parts in separation of keratinocytes and degeneration of split-desmosomes in pustules of dogs with PF.

There remain many challenges in using historical documents to reconstruct a reliable history of earthquakes in Japan. Previous catalogs of historical earthquakes in Japan are not conclusive and contain uncertainties about date, hypocenter, magnitude, and tectonic interpretation of each earthquake. There is no database of digital texts of historical documents, which describe each earthquake. Since the density of historical records in Japan is temporally and spatially heterogeneous, seismologists should carefully remove apparent changes of earthquake frequency, which are caused by the heterogeneity of record density. There is, however, no detailed database of the density variation of historical records. The number of researchers, who are interested in historical earthquakes, is small.<BR>The situation stated above is caused mainly by the multi-disciplinary character of historical seismology. Japanese seismologists, who usually have little knowledge of history and classical literature, are not qualified to read a historical document and evaluate its reliability.<BR>The environment for research on historical seismology is, however, getting better. Japanese historians have published and are still publishing many historical documents, sometimes with translations into modern language. Evaluations of the reliability of each document can easily be done by referring to historical dictionaries or other databases. All these publications and information are available in many libraries. It is now easy and stimulating for many seismologists to read, evaluate, and interpret historical documents.

我々は、60GHz帯を用いた無線通信方式として、高速化に伴うサンプリング速度・PAPR(Peak to Average Power Ratio)・信号帯域等の増加によるアナログ回路への負担を軽減すべく、マルチキャリアMSK(Minimum Shift Keying)変調方式の提案を行っている。本発表では、提案方式をFPGA(Field Programmable Gate Array)へ実装し、ベースバンド信号の変復調を行った結果、500Mbpsの速度での通信を実現したことを報告する。

Various digital media have intimate relationship with every field of communication that produces certain message while accepting information and make conversation. Also, technical characteristics of new media change the individual way of communication. In this research, we believe that we can make communication affluent by introducing classified items like movement of icon representing emotion, gesture, situation, and so on. This can be done by comparative analysis between context and visual stimulation of icon. In other words, it becomes possible to find out the way to be a integrated communication tool that can deal with emotional change among people.

症例は58歳男性. 右下腹部痛と下痢を訴え受診. 7年前胃癌にて胃全摘術施行. 注腸で横行, 下行, S状結腸と直腸に壁の辺縁硬化や鋸歯状不整を伴う全周性狭窄と粘膜の顆粒状小隆起を認めた. 内視鏡で同部の粘膜が浮腫状に肥厚し, 浅い潰瘍や半球状の顆粒集族も認めた. 生検上低分化腺癌・印鑑細胞癌を認め原発性びまん浸潤型大腸癌または胃癌による転移性びまん浸潤型大腸癌を疑い手術施行. 腹膜播種なく左半結腸切除および直腸切断術を施行. 病理組織で初回手術の胃癌同様, 粘膜下層中心に漿膜下までの癌浸潤と間質結合組織増生を認め, 胃癌による4領域を越える転移性大腸癌と診断した. 転移性大腸癌は原発巣術後5年以上でも発症し, 臨床的所見に乏しいことがあるため注腸等による定期的な画像診断が有用だが原発性びまん浸潤型大腸癌との鑑別が必要である. 転移巣切除後の予後は良好でないが, 治癒切除可能ならば原発性大腸癌に準じた手術を行うべきである.

ウイルス進化論を模した遺伝的アルゴリズムが開発され、組み合わせ問題に適用された。この研究におけるアルゴリズムはひとつの個体とたくさんのウイルスを用いる。個体はウイルスにより攻撃され、感染され、改良される。ウイルスは二つの遺伝子(トップ遺伝子とテイル遺伝子)からなる。もし個体が攻撃によって改善されれば、感染が起こる。局所解を抜け出すために、感染に余裕率を設けている。感染後、ウイルスのテイル遺伝子は突然変異される。もし同じウイルスが数回攻撃し、感染しなかったならば、トップ遺伝子が突然変異される。個体はこの突然変異により、効率的に改善される。最適解を得るために、部分攻撃がまた有効である。A genetic algorithm that simulates the virus evolutionary theory has been developed and applied to combinatorial optimization problems. The algorithm in this study uses only one individual and a population of viruses. The individual is attacked, infected and improved by the viruses. The viruses are composed of two genes (a top gene and a tail gene). If the individual is improved by the attack, infection occurs. To escape from local minima, an infection allowance is set. After the infection, the tail genes are mutated. If the same virus attacks several times and fails to infect, the top genes of the virus are mutated. The individual can be improved effectively using this mutation. To obtain the optimal solution, "sub-attack" is also useful.
