年,Webでは集合知と呼ばれる多くの人々を活用した知性が注目されている.集合知を実現するための条件をSurowieckiは多様性,独立性,分散性,集約性の4つにまとめている.今回,複数グループによる分散協調型KJ法で出された意見を用いることによって,集合知を指向した会議を検討した.第1段階目は,十数人の人々が独立したグループに分かれて分散協調型KJ法を行う.第2段階目は,それら結果を集約または集合させて分散協調型KJ法を行う.実験結果より,(1)集約性の高い会議技法においてまとめ文章の結果が良いこと,(2)その会議技法の参加者は第1段階目と関係ない参加者でも良い結果を導き出せる可能性が分かった. : A collective intelligence with groupware technology has been expected to produce good results. J. Surowiecki proposed success of the intelligence to be endowed with the four conditions: diversity, independence, decentralization and aggregation. A conference technique is considered to support the four conditions. In this consideration, the cooperative KJ method is carried out with more ideas obtained from some ten conferences by some groups in the first step. The technique utilizes all ideas or good ideas selected from previous ordinary conference in the second step. The experimental results showed that (1) the conference with good ideas had good aggregation and produced good results, and (2) the meeting had good performance by another group, not participated in the previous conferences, too.

65歳女.肉眼的血尿で膀胱内腫瘍を指摘された.膀胱はコアグラタンポナーデの状態で,膀胱洗浄により血塊と共に悪臭の強い多量の壊死組織が排出された.膀胱鏡では左側壁から後壁を中心とする非乳頭状広基性腫瘍を認め,膀胱粘膜全体が表面不整であった.骨盤部造影CTで膀胱左側壁を中心とする8×6cmの腫瘍を認め,膀胱壁は全体に肥厚していた.1週間後の膀胱造影では左側壁からの造影剤漏出を認めた.膀胱癌T4N2M1と診断し,発熱が増悪するため膀胱全摘術及び両側尿管皮膚瘻造設術を施行した.摘出組織で表面を壊死組織で覆われた灰白色の腫瘍を認め,膀胱壁外に到達した部分に瘻孔が形成されていた.組織学的には表在性に位置する癌腫の部分と,優勢な肉腫様部分で構成され,両者の境界は明瞭であった.癌腫は扁平上皮に分化している細胞,肉腫様部分は未分化な紡錘形細胞で構成されていた.術後一時的に改善したが発熱が再燃し,2週後に敗血症で死亡したA 65-year-old woman was referred to our clinic with gross hematuria. Cystoscopy revealed a non-papillary and non-pedunculated tumor on the left lateral wall of the bladder. A piece of necrotic tissue obtained from the bladder irrigation was histologically squamous cell carcinoma. A perforation at the left lateral wall of the bladder was found on the cystogram. Bone scintigraphy showed multiple metastases and computed tomography scans showed multiple lymph node metastases in the pelvic cavity. The clinical diagnosis was bladder carcinoma of T4N2M1 stage with an abscess due to a spontaneous perforation. Total cystectomy with bilateral ureterocutaneostomy was performed. She died due to sepsis 13 days after the operation. Histologically, the tumor was composed of carcinomatous and sarcomatous elements. The carcinomatous element was compatible with squamous cell carcinoma and the sarcomatous element was composed of undifferentiated malignant spindle cells. Immunohistochemical examination showed that the carcinomatous component was positive for keratin and human chorionic gonadotropin (HCG) and the spindle cell component positive for vimentin, desmin and HCG. Therefore, we diagnosed the tumor as sarcomatoid carcinoma. We reviewed 56 cases of carcinosarcoma of the bladder in Japan and discussed the clinicopathology of the disease.

Among the most important daimyo of early modern Japan to embrace and promulgate Confucianism were Tokugawa Mitsukuni of Mito and Ikeda Mitsumasa of Okayama, and both were naturally keenly interested in Confucian ritual practices. Confucianism particularly flourished in Mito during Mitsukuni's era and later, at the end of the Tokugawa period, when Tokugawa Nariaki was daimyo of the domain. But throughout this period, Mito Confucianists conducted an earnest inquiry into the proper procedure for the conduct of funeral and ancestral rites, in which Zhu Xi's Jiali (Family Rituals) functioned as a key text. This paper will trace the development of Confucian ritual practice in Mito, accompanied by a broad examination of the textual sources related to funeral and ancestral rituals. In addition, although some scholars have argued that funeral rites in Mito were conducted in a Shinto style, this paper provides evidence that this is a misinterpretation and that Mito funerary rites were fundamentally Confucian in nature.
