The purpose of this study was to develop prediction models of sarcopenia in 1,894 Japanese men and women aged 18-85 years. Reference values for sarcopenia (skeletal muscle index, SMI; appendicular muscle mass/height2, kg/m2) in each sex were defined as values two standard deviations (2SD) below the gender-specific means of this study reference data for young adults aged 18-40 years. Reference values for predisposition to sarcopenia (PSa) in each gender were also defined as values one standard deviations (1SD) below. The subjects aged 41 years or older were randomly separated into 2 groups, a model development group and a validation group. Appendicular muscle mass was measured by DXA. The reference values of sarcopenia were 6.87 kg/m2 and 5.46 kg/m2, and those of PSa were 7.77 kg/m2 and 6.12 kg/m2. The subjects with sarcopenia and PSa aged 41 years or older were 1.7% and 28.8% in men and 2.7% and 20.7% in women. The whole body bone mineral density of PSa was significantly lower than in normal subjects. The handgrip strength of PSa was significantly lower than in normal subjects. Stepwise regression analysis indicated that the body mass index (BMI), waist circumference and age were independently associated with SMI in men; and BMI, handgrip strength and waist circumference were independently associated with SMI in women. The SMI prediction equations were applied to the validation group, and strong correlations were also observed between the DXA-measured and predicted SMI in men and women. This study proposed the reference values of sarcopenia in Japanese men and women. The prediction models of SMI using anthropometric measurement are valid for alternative DXA-measured SMI in Japanese adults.

Japan has more in-patient days than any other country, as well as the highest number of beds in mental hospitals as a ratio of the total population. People with mental disorders used to be hidden away under the law, either in the medical or welfare system, and suffered from a social stigma. In recent years, however, mental patients have left such isolated medical institutions and started to live among the general community, not as psychiatric patients but as persons whose will is respected and who can get social-welfare support. As that drastic paradigm shift happened rapidly, Japanese institutions for persons with mental illness have come to design various support systems in response. This paper describes the experiences of several schizophrenic persons who utilize a social welfare facility in Hokkaido: Bethel's House in Urakawa, which has developed unique ideas about dealing with schizophrenic symptoms. The members of Bethel's House diagnose their own symptoms on their own terms, and are able to study their physical conditions, sensuous feelings, and mental worlds through their own experiences of living in the community. They carry out that work studies with friends - the other members of Bethel's House - and develop and train skills for communication with their friends and the rest of the real world. The paper looks at the case of a woman at Bethel's House who had difficulty holding down a job because of voices she heard and hallucinatory delusions she saw. She only realized that the voices and hallucinations might be coming from her own mind after talking with the other members of the house. Although she suffered from the voices, she gradually gained skills to communicate with her "friends." The staff members of Bethel's House did not try to ignore the voices, but instead were told to greet them (the "friends" were just the voices that she had heard). The staff members also urged her to try to experiencing talking with her friends using those greetings. Through such daily communications, schizophrenic persons at Bethel's House, such as this woman, learn to have specific physical experiences using their own words, thereby constructing practical communities. We also found that medical institutions and welfare facilities in Japan have kept away schizophrenic experiences, having removed patients from the community in the context of psychiatric treatment, responsible individuals, and human rights. In contrast, Bethel's House lets schizophrenic persons live with their voices and hallucinations, meaning that they live in a continuous world that includes both the hospital and the outside world. On the other hand, some residents in Urakawa Town wanted to exclude Bethel's House from the community because they felt it was accommodating "irresponsible" or "suspicious" persons, or subsidizing non-working people with public monies from the town budget. Although individual daily contact was maintained between Urakawa residents and the members of Bethel's House, those exclusionary attitudes against social institutions meant that Bethel's House has come to function as an asylum for schizophrenic people in such situations, increasing the feeling of isolation in schizophrenic persons' lives, both internally and externally.

Recently, we can find many studies which insist on appreciating the concept of place in a contextual way not only in the English speaking world but also in Japan. In this renewed concept, place is contended to be humanly (socially) constructed with spatial practices, We (the user) make sense of place by the spatial practices, through which the user creates his own behavior and acts place-ballet. In the socio-spatial studies, Sack (1988) and Shields (1991), for example, advocate this point of view and contend that understanding of many factors operating in the place-making, the invention of place, and the construct of place, should be a primary theme in this discipline. Drawing attention to the conceptual framework of 'genealogy of place', this paper aims at describing the historical transition of amusement quarters (Sakari-ba) of Osaka Sennichimae. Osaka Sennichimae is one of Sakari-ba, where marginality and 'carnivalesque' dominated and both ephemeral and temporal logic was considered as those alternative to everyday rife working. Originally, Sennichimae was a grave yard on the margin of built-up areas of Osaka city in Edo era. After Meiji Restoration, this grave yard changed to an amusement site at first, and then, this site gradually transferred to Sakari-ba. Therefore, the name of this place, Sennichimae, had evoked people with both horror and pre-modern 'Edo' nostalgia after redeveloping from the grave yard into Sakari-ba. In the case of Sakari-ba Sennichimae, this paper examine the very constructed place as a genealogy interwovened with the historical place-images, the interventions of political powers, the act of show-planners (Yashi), and the spatial practices of the walkers. The development of Sennichimae as Sakari-ba is outlined as follow. In the early Meiji period, Sennichimae changed its landuse from grave yard to amusement site. This change might suggest two aspects. Firstly, the place as grave yard was cleared out for the sanitary reason. Secondly, at the same fane, the government of Osaka prefecture carried out the project of improvement in the old section of the city. Neverthless, the former image of grave yard influenced contingently the proceeding devlopment of amusement quarter of Sennichimae. Introducing many of new leisure attractions, especially cinema, this place was gradually characterized as Sakari-ba, and created the typical landscape of amusement site, and, in the 1920's, Sennichimae attracted people who loved to walk around as flaneur, and enjoyed their practice of walking, seeing, and being in the space of Sakari-ba with the mass.

観測データからシステムの内部状態を求める逆問題は第一種Fredholm積分方程式を解くことに帰着することが多い。しかし、第一種Fredholm積分方程式には解析解がないので、数値解法として差分近似の連立方程式を解くことで対処するかが普通である。1960年代に入り、Tikhonov、Phillips、Twomeyらによって、一種の近似解の解法が確立された。これらの解法では通常測定データに誤差が入ると解が振動するため、これを滑らかにすることを目的として、Lagrange未定常数を導入している。この常数の選び方あるいは最適値については、多くの研究がされているが、最もよい方法がないのが現状である。本研究ではニューラルネットワークを用いて第一種Fredholm積分方程式の新しい近似解法を提案する。本手法は積分方程式の性質を、実例を用いてニューラルネットワークに学習させ、ネットワークのニューロン間の結合係数に覚えさせ、そして、誤差を含んだ未学習の測定データ(ネットワークの入力)に対しても、安定な解(出力)を得るものである。

Though many different pathologies cause vomiting, they can be divided into three categories. The first is vestibular vomiting such as that caused by motion sickness. The second is vomiting mediated by chemoreceptor trigger zone (CTZ) in the area postrema, such as that seen in poison-induced vomiting. The third is vomiting from the gastro-intestinal tract. Vestibular stimuli, signals from the CTZ, and afferent signals from the gastro-intestinal tract stimulate the vomiting center in the medulla to cause vomiting independently.Histamine H1-blockers (diphenhydramine, promethazine) prevent vestibular vomiting selectively. Dopamine D2-blockers (metoclopramide, domperidone) act on the CTZ to inhibit CTZ-mediated vomiting. Serotonin 5-HT3-blockers block afferent signals from the stomach induced by cisplatin. Diphenidol may inhibit the vomiting center because diphenidol prevents both motion and cisplatin-induced vomiting.
