| 抄録 | A square root (SQRT) algorithm in extension field F(p(m))(m = r(0)r(1)･･･r(n−1)･2(d), r(i) : odd prime, d : positive integer) is proposed in this paper. First, a conventional SQRT algorithm, the Tonelli-Shanks algorithm, is modified to compute the inverse SQRT in F(p(2d)), where most of the computations are performed in the corresponding subfields F(p(2i)) for 0 ≤ i ≤ d-1. Then the Frobenius mappings with addition chain are adopted for the proposed SQRT algorithm, in which a lot of computations in a given extension field F(p(m)) are also reduced to those in a proper subfield by the norm computations. Those reductions of the field degree increase efficiency in the SQRT implementation. The Tonelli-Shanks algorithm and the proposed algorithm in F(p(6)) and F(p(10)) were implemented on a Core2 (2.66 GHz) using the C++ programming language. The computer simulations showed that, on average, the proposed algorithm accelerated the SQRT computation by 6 times in F(p(6)), and by 10 times in F(p(10)), compared to the Tonelli-Shanks algorithm. |

| 抄録 | A series of ferroelectric glass-ceramics was elaborated by the controlled growth of Ba(1-x)Sr(x)TiO(3) crystal particles in the glass system 60[Ba(1-y)Sr(y)]TiO(3)-10Al(2)O(3)-30SiO(2)(0≦y≦0.2) in molar basis. Analysis of crystal phases by X-ray diffraction revealed that Sr content in Ba(1-x)Sr(x)TiO(3) increased with increasing content of SrO in glasses by its preferential transfer into the crystal phase, and the appropriate temperature for the crystal growth was 1100°C. Curie temperatures of glass -ceramics shifted to lower temperature with increasing SrO content in the crystal and comparatively high dielectric constant was obtained at room temperature for a glass-ceramics with y=0.2. Frequency dependences of dielectric constant and loss tangent were examined in the frequency range from 1 K to 1 M Hz. |

| 抄録 | On the flow injection analysis (FIA) of chemical oxygen demand (COD), silver salt was added as an oxidation catalyst for COD substances and a masking agent for halide to improve operating conditions of the FIA apparatus. Both of a proper concentration of potassium permanganate solution and 6.0 % sulfuric acid solution containing 0.1 % silver nitrate are individually pumped up with respective flow rates of 0.51 ml min(-l) and merged into a carrier stream. A 20 μ1 of sample solution is injected into the flow of sulfuric acid solution at just before the merging place. The sample mixed with the carrier solutions in a reaction manifol(polytetrafluoroethylene tubing: 0.5 mm i.d. x 30 m), is passed through a thermostated bath at 100 °c and led to a flow cell for the absorbance measurements at 525 nm. The absorbances are continuously recorded with time. The peaks in the recordings showed good reproducibility and the calibration obtained at a linear concentration range of 0 - 170 mg 1(-1) COD with glucose as standard. The detection limit and precision confirmed with this method were 5 mg 1(-1) and 0.8 %, respectively. Chloride ion up to 200 mg 1(-1) did not interfere without elimination of a silver chloride precipitate. By the present FIA method, several industrial waste water samples were analyzed at a sampling rate of about 40 samples per hour, and their apparent COD values were compared with those found by the manual JIS method. Both of the methods gave the similar results within an error range from -35 to +5 %. |

| 抄録 | The glass forming limit by substitution of CdS for CdO in a CdO-B(2)0(3) glass was determined by chemical analysis. When x CdS-(60-x)CdO-40B(2)0(3) nominal mixtures in weight ratio were heated at 1100°C in flowing nitrogen gas for 1/2 hour, about 40~50% of mixed CdS and 10-15% of the mixed CdS were evaporated. The limit of nominal composition for glass forming was 10CdS-50CdO-40B(2)0(3) and the corresponding virtual composition after the above heat treatment was found to be 4.9CdS-46.4CdO-48.7B(2)O(3). Further addition of CdS made the melt devitrefied with CdS precipitation. D.C. conductivity measurements revealed that the current density was not linear with respect to the applied voltage, but the resistivity ranged around 10(12)Ω･cm for 4.1CdS-48.8CdO-47.1B(2)O(3) (virtual composition) glass and around 10(11.5)Ω·cm for 4.9CdS-46.4CdO-48.7B(2)O(3) glass. These sulphur containing glasses did not show photoconduction, although CdS-precipitated materials showed slight photoconductivity when disposed in ultra violet radiation. Apparent dielectric constant and tan 8 were also measured as a function of frequency, revealing a moderate dispersion in the CdS-precipitated glasses. |

| 抄録 | Skin tests, serum total IgE levels, specific IgE antibodies against each allergen, bronchial reactions provoked by allergens and histamine release from basophils are well known as prameters of immediate allergic reactions. The incidence of positive immediate skin reaction to allergens such as house dust, ragweed, Aspergillus Alternaria, Cladosporium and Broncasma decreased with aging. On the other hand, the incidence of positive skin reaction to Candida albicans was higher in cases between the age of 41 and 50 and cases over the age of 61 compared to that in the other groups classified by age. Serum IgE levels was highest in cases aged between 0 and 30. The levels of serum IgE decreased with aging. The incidence of positive RAST scores (more than 2+) and positive bronchial reaction to house dust were highest in cases between 0 and 30, and decreased with aging. However, the positive ratio of these tests against C. albicans were highest in cases between 41 and 50. The degree of histamine release from basophils of asthmatics induced by anti-IgE was consistently high without any correlation to aging when their serum IgE levels were more than 501 IU/ml. In the cases with serum IgE levels of less than 300 IU/ml, basophil reactivity to anti-IgE decreasd with aging. Basophil reactivity to house dust was generally dependent on the levels of specific IgE antibodies against the allergen. Although basophil reactivity to C. albicans was also high in cases with positive RAST scores, some cases with a RAST score of 0+ or 1+ showed high or moderate basophil reactivity. Moderate or high reactivity of basophils was frequently observed in cases between 41 and 50 and cases over age 61. |

| 抄録 | カレジダ特異的IgG及びIgG(4)抗体が,気管支喘息の発症病態に関与しているかどうかについて検討を加えた。カンジダ特異的IgGおよびIgG(4)抗体は, 0-30才の年齢層の症例ではアトピー性素因の強い症例で,また,31-60才の年齢層の症例ではストロイド依存性重症難治性喘息症例で,さらに61才以上の高年令の症例で,その産生亢進が観察される｡これらの症例におけるIgG及びIgG(4)抗体産生は,0-30才の年齢ではアトピーとの関連で,また31-60才の年齢では副腎皮質ホルモンの長期投与と関連して,さらに61才以上の症例では加齢と関連して,細胞性免疫能が低下し,そのためカンジダの発育が促進され,その結果として,IgG及びIgG(4)抗体の産生亢進が見られることが明らかにされている｡すなわち,気管支喘息におけるカンジダに対するIgG系抗体の産生亢進は,cell-mediated immunityの低下と言う共通の基盤を有しており,病因的意義とは必ずしも関連していないことを述べた。 |

| 抄録 | Serum cortisol levels were examined in 94 patients with bronchial asthma in relation to dose of glucocorticoids and age. 1. The level of serum cortisol was significantly lower in group A patients, treated with glucocorticoids (prednisolone of 5mg/day or more) for more than 2 years, (2.4±1.2mcg/㎗) than in group B, treated with glucocorticoids (prednisolone of 5mg or less) for less than 2 years, (6.8±3.7mcg/㎗) (p<0.001) and in group C, treated without glucocorticoids, (12.6±3.9mcg/㎗) (p<0.001). The serum cortisol level was also significantly lower in group B than in group C (p<0.001). 2. The level of serum cortisol was significantly lower in patients over the age of 70 compared to that in those aged between 0 and 39 years (p<0.01) and those between 40 and 49 (p<0.05), and those between 50 and 59 (p<0.02). The level was also lower in patients between 60 and 69 compared to that in those between 0 and 39, however, this was not significant. These results demonstrate that the level of serum cortisol decreases by long-term glucocorticoid regimen and with aging. |

| 抄録 | The purpose of this study is to establish a new, non - invasive diagnostic technique for peripheral circulation in patients with diabetes mellitus in the early stage of arteriosclerosis obliterans (ASO) as one of the complications of diabetes mellitus. We observed peripheral circulation quantitatively by thermography and Laser- Doppler blood flowmetry. The body surface peripheral circulation in 27 patients with diabetes mellitus, including 14 males and 13 females with a mean age of 67.4 years (range from 51-82 years), and with a mean hemoglobin A1C (HbA1C) 019.5% (range from 6.8%-13.0%), and who were suffering coldness, numbness or pain in their feet, was examined using thermography and Laser- Doppler blood flowmetry. Thermographic results
were analyzed quantitatively by calculating a recovery ratio as : Recovery ratio= [Total counts of thermography (Pixels) over temperature (T) after cold -loading] + [Initial counts over T after hot-loading] Xl00 (%). Results of recovery ratios for 27 cases were 0% - 93.5%, and the average was 34.0%. At the same time, the blood flow after cold -loading was 0.91 - 5. 36ml/min/lOOg tissue and the average was 2.04ml/min/l00g tissue. We found that the recovery ratio
and the blood flow were correlated (r=O. 634, p |
