| Abstract | A parallel tight-binding molecular dynamics with an order-N [O(N))] algorithm is implemented to perform large-scale simulation of nanostructured materials. The algorithm is based on the Fermi-operator expansion of an electronic energy and force, and we present its basic formalisms. Accuracy necessary for molecular-dynamics simulations can be obtained by a proper truncation in the expansion. Parallel efficiency on a parallel PC cluster shows nearly ideal scaling behavior with respect to the number of processors. Applicability of the method to a silicon-carbide system is examined. |

| Abstract | The behavior of multicomponent plasmas in the Penning-Malmberg traps is discussed with the parameters corresponding to experiments with antiprotons and cryogenic electrons. The relaxation times for the energy transfer antiprotons to electrons and between parallel and perpendicular components of electrons are estimated. It is shown that, depending on the values of parameters, both the former and the latter can be the bottleneck in the cooling process. |

| Abstract | Density functional molecular dynamics method is applied to hydrogen plasma in the domain of liquid metallic hydrogen. Tentative results for the proton-proton pair distribution function and the electron-proton pair distribution function are obtained. It is shown that with the increase of the parameter γ(s), we have increasingly strong screening of proton charge by electrons and the decrease of electron density in the domain between protons. |

| Abstract | 近年，各種膵疾患に対する検査法の発達には目を見張るものがあるが，実際の運用にあたっては各検査法の適応，限界，組合わせおよび実施する順序等に迷うことが少なくない。本研究では，最近我々が経験した慢性膵炎Ⅰ群116例の診断過程を振り返ることにより，慢性膵炎の診断における理想的な検査法の組合わせとそれぞれの役割を検討し，同時に診断名のみならず病態と病期が容易に理解できる表現方法を提案した。画像診断法，膵外分泌機能検査法（EX），膵内分泌機能検査法（EN）を比較検討し，以下の結果を得た。①画像診断法は必須である。②内視鏡的逆行性膵胆管造影（ERCP）を軸とした腹部超音波検査（US）あるいは腹部CTスキャン（CT）の組合わせは欠くことができない。③EXもまた必須の検査法である。④ENは慢性膵炎の診断に必要不可欠ではないが，治療方針を決めるうえで重要である。⑤純粋膵液（PPJ）の生化学的検査と組織化学的検査は膵炎の診断と病態生理の解明に重要である。⑥PPJ中の細胞診は慢性膵炎に合併した膵癌の検索に有用である。⑦以下に示すような診断の記載方法を提案した。"Calcified chronic pancreatitis, alcoholic, diffuse, ERCP-3, US-2, CT-3, EX-2, EN-1, Lf(＋)"。 |

| Abstract | It is difficult to evaluate a biomechanical properties quantitatively. The authors developed the measurement system of biomechanical properties formerly but it is on a large scale because of the use of personal computer. In this study, the portable measurement system of biomechanical impedance/mobility is developed. To establish a rapid measurement, a random vibration is adopted in input signal. The system consists of the measuring probe, amplifier, and a note-typed personal computer. The measurement probe is developed newly, and has an overall length of 9 ㎝ (without a handle) and a total weight of about 500 g. The measurement program is also developed and is available to any computer which is worked under MS DOS compatible in Windows 95/98 operating system. The biomechanical spectra of thigh, temple and forehead are obtained and they show three typical spectrum patterns. |

| Abstract | The acousicmyogram (AMG) is a mechanical phenomenon recorded at the surface of an active muscle. It is used to monitor force production, fatigue, and contractile properties of muscle. In this study, the new electrode with accelerometer for electrostimulation and acoustic detection. It consists of Ag-AgCl active electrode and solid-gel annular groud, and a very light piezoresistive accelerometer. The recorded AMG waveform depends on the pulse amplitude and duration of stimulation current and its lag from the electroatimulation is about 7 ms. The strengh-duration (S-D) curve (the threshold current for stimulation vs. pulse duration) describes the excitability of muscle. The left forearm is electrostimulated by using the same electrode and the muscle vibration (AMG) is recorded with accelerometer. During the muscle fatigue, the S-D curve changes and the current threshold increases under the same pulse duration. The rheobase of S-D curve increases gradually but the chronaxie hardly changes during muscle fatigue. |

| Abstract | 膵外分泌機能に及ぼす加齢の影響を検討する目的で，健常人43名，非膵疾患患者41名，老人ホーム入居者39名を対象として比色法により糞便中キモトリプシン活性（FCA）を測定し，以下の結論を得た。1）FCAは逐齢的に低下し，60歳以上は60歳未満より有意の低値を示した。しかし，分布図のretrospectiveな検討からは，膵外分泌機能の低下は，実際には65～70歳あたりから明らかになることが示唆された。2）FCAの正常下限値を14.5U/gに定めたが，高齢者の診療にあたってはこの正常値のみを根拠にして疾病の有無を判定すべきではない。3）老人ホーム入居者のFCAは特に低値を取ったがその主要因は高齢者が多いためと考えられた。 |

| Abstract | A set mathematical models was developed for predicting the performance of an open-type flat-plate solar collector, and solved numerically through an implicit difference method. The effects of various parameters on the absorption of solar energy for the collector were investigated. The results showed that the solar energy absorptance of the open-type flat-plate collector was relatively high especially for the region where the weather was humid and hot, and there were an optimum length and an optimum tilt angle for the absorbing plate on which the collector could obtain the highest solar energy absorptance. It was found that the latent heat flux of water evaporation could be 5 to 15 times larger than the sensible heat flux. The effects of the magnitude of the solar incident flux, the atmospheric humidity, the atmospheric temperature, the absorbing plate tilt angle, and water film thickness on the temperature rising of the water film were clarified in numerical quantities. The increase of the solar incident flux, the atmospheric humidity or the atmospheric temperature also resulted in a rise in the energy absorptance of the collector. |

| Abstract | A new type of hydrocyclone with a perforated inner cylinder is tested experimentally to study its performance for liquid-solid separation. The size of the cyclone is small so that it may be effective for small particle separation. Two types of the inner cylinder were made : the one has 39.5% void fraction of the perforated surface and the other has 73.5% . The mean particle diameter is 4.5 μ m. It is found that the pressure loss of the cyclone with the inner cylinder is reduced by about 25% compared with that of the ordinary type. The new type cyclone has better separation efficiency. |

| Title Alternative | An application of artificial CO(2)-bathing for psychosomatic disorders in childhood |
| Author | Komoto, Junko| |
| Abstract | 人工炭酸浴剤浴（パブ浴）は，末梢循環改善作用を有して組織に賦活力を与え，皮膚創傷治癒を促進させる。全身に引き掻き傷を有する心身症の少女2症例に対して，母親とともにパブ浴を常用させた。何れの症例においても，皮膚創傷治癒をみて，患児，および母親に治療者を頼ってみようという，いわば治療への動機づけが促がされ，入浴という手段で児童の最大のストレスである母子関係の阻害に対し脱ストレス的に働き患児とのラポールがえられるようになった。パブ浴には副作用は全くなく，児童期の様々な心身症に応用されてよいであろう。 |
