| 抄録 | Permeation rate of hydrogen through a gold cell made as a reaction vessel for a Dickson-type hydrothermal apparatus was measured at 50°intervals from 300°to 450℃ under a hydrothermal condition. The gold cell chosen for the measurement had a shape and size illustrated in Fig. 1 when it was fully expanded, and was a typical one in the meaning that it had been used several times for hydrothermal experiments (its total history may be equivalent to one month at 490℃) and that it had a body enlarged by about 8% in diameter from the original size as a result of pinhole check made by applying a gas pressure to the inside. The cell was filled with an appropriate amount of pure water, placed in a pressure vessel made of Ni-base alloy, pressurized by injecting water to the outside of the cell and kept under predetermined temperatures and pressure (=1 kbar). Meanwhile, small fractions of the waters inside and outside the cell were sampled at times and analyzed for H(2) gas-chromatographically as described in ref. (5). H(2) concentrations in the samples (CH(2)) were converted to H(2) fugacity values by using the conversion factors (Y) given in ref. (6). At each temperature, the permeation rate (k) of H(2) through the cell is evaluated by correlating the measured fH(2) values with time (t) according to eq. (2), where fo is the fH(2) in the outer water and is a constant, and fi and m are the fH(2) in and the mass of the inner water, respectively. The relevant data and results are shown in Table 1. The present data for the permeation rate φ, expressed in c㎥ H(2) at STP per 1c㎡ surface area, 1 mm wall thickness, 1 (bar)(1/2) of (fH(2))(1/2) difference and 1 hour, are plotted in Fig. 2 in relation to 1/T (K) and compared with one available data, which is a combination of reported solubility and diffusion coefficient data for hydrogen into gold at higher temperatures. The present data can be fitted into eq. (3). The present result may be of importance for hydrothermal experimental studies of geochemical redox reactions and of hydrogen isotope exchange reactions, and the technique used may also be important as a new, simple method of measuring hydrogen permeability through noble metals. |

| 抄録 | Histamine release from basophils induced by anti-IgE was examined in 14 asthmatic subjects with blood eosinophilia. The subjects were divided into two groups; group I (with blood eosinophilia, positive skin test and positive RAST to house dust) and group II (with blood eosinophilia, negative skin test to various allergens and negative RAST to house dust). 1. Serum IgE levels in group I were much higher than those in group II. 2. Maximum percent histamine release induced by anti-IgE was much higher in group I than in group II. 3. Dose-response curve of anti-IgE-induced histamine release in group I showed consistent increase as anti-IgE concentrations increased. while, dose-response curve in group II was very low. These findings suggested that blood eosinophilia in group I might be elicited relating to IgE-mediated reaction. However, mechanism causing eosinophilia in group II was not clear in the present study. |

| タイトル（別表記） | An application of the artificial CO(2) bath for enuresis |
| フルテキストURL | pitsr_056_009_011.pdf |
| 著者 | 古元 順子| 古元 嘉昭| |
| 抄録 | The artificial CO(2) bath was prescribed for two enuretic boys with bladder-sensitive or parasympaticotonic type. A tablet of 50 g, made from sodium bicarbonate and succinic acid, was put in a bath-tub of 150-200 L at 40℃. Each patient was recommended to take a bath with his mother longer than ten minutes, and to mark the presence or the absence of enuresis every day. Outcome results of case 1 on CO(2) bath is shown in tabel 1 and results of case 2 on CO(2) bath is shown in table 3. Both two cases became free from enuresis 7-10 days after the initiation of the artificial CO(2) bathing. Etiological mechanisms of enuresis seem to be multi-factorious, with underlining networks of central- and autonomous nerve systems for the control of sleep and bladder. It is suspected that some improvement of peripheral circulation by CO(2)-bathing leading to keep the body warm may be one of the contributing factors which prolong the intervals of urination, resulting in autonomous normalization, at least, for the cases of bladder-sensitive enuresis, Further case studies are needed to support this assumption. |

| 抄録 | A role of the global-scale Asian Monsoon on the rainfall climatology around the Japan Islands (excluding that in Hokkaido) during warm season were discussed by reviewing the previous studies including the original results by the present author. Not only the mean monthly rainfall amount but also its year-to-year variation is large from June to September (or October) there. While the rainfall amount and its variation are especially large in the Baiu season in Kyushu, they relatively large in autumn rainfall season (so-called the "Akisame" or "Shurin" in Japan) . It is noted that the huge northward moisture transport from the moisture-rich subtropical high area to the Baiu frontal zone is largely affected by the low pressure area in the subtropical region around South Asia. On the other hand, the low pressure area associated with the stagnation of typhoons around the Southwest Islands area (to the southwest of the Japan Islands) seems to play an important role in the huge moisture transport toward the japan Islands in the autumn rainfall season. A comment on seasonal persistency of the rainfall anomaly from spring to summer and summer to autumn is also presented by examining the monthly rainfall data in Nagoya, the central part of the Japan Islands. |

| 抄録 | 本稿では、筆者の提示する「対照性と類似性を基軸とした比較による鑑賞教育方法論」の展開として、比較鑑賞教育法における美術作品の提示方法について考察した。そこではまず、鑑賞教育に関する大規模調査の結果をもとに、鑑賞教育の普及の実態について考察し、作品の提示方法という鑑賞教育における基礎的事項が、鑑賞教育普及上の実際的な問題であることを指摘した。そして、複製を主とした比較鑑賞における作品提示方法を、作品の提示媒体と提示形態に分けて、それぞれを類型的に考察しその特質を論じた。この後、これらを組み合わせて、比較鑑賞における作品の提示方法について考察した。 |

| 抄録 | We present highly accurate least-squares (LS) alternatives to the theoretically optimal maximum likelihood (ML) estimator for homographies between two images. Unlike ML, our estimators are non-iterative and yield solutions even in the presence of large noise. By rigorous error analysis, we derive a “hyperaccurate” estimator which is unbiased up to second order noise terms. Then, we introduce a computational simplification, which we call “Taubin approximation”, without incurring a loss in accuracy. We experimentally demonstrate that our estimators have accuracy surpassing the traditional LS estimator and comparable to the ML estimator. |

| 抄録 | This paper presents a new method for fitting an ellipse to a point sequence extracted from images. It is widely known that the best fit is obtained by maximum likelihood. However, it requires iterations, which may not converge in the presence of large noise. Our approach is algebraic distance minimization; no iterations are required. Exploiting the fact that the solution depends on the way the scale is normalized, we analyze the accuracy to high order error terms with the scale normalization weight unspecified and determine it so that the bias is zero up to the second order. We demonstrate by experiments that our method is superior to the Taubin method, also algebraic and known to be highly accurate. |

| 抄録 | We present an alternative approach to what we call the “standard optimization”, which minimizes a cost function by searching a parameter space. Instead, the input is “orthogonally projected” in the joint input space onto the manifold defined by the “consistency constraint”, which demands that any minimal subset of observations produce the same result. This approach avoids many difficulties encountered in the standard optimization. As typical examples, we apply it to line fitting and multiview triangulation. The latter produces a new algorithm far more efficient than existing methods. We also discuss optimality of our approach. |
