‘OC-Hemocatch’, an immunochromatographic test for the detection of fecal occult blood was evaluated for the forensic identification of human blood. ‘OC-Hemocatch’ showed positive results for human blood to a dilution of 1:500,000 and provides the strongest detection line for a dilution of 1:20,000. On the other hand, the human blood diluted to 1:100 was negative for ‘OC-Hemocatch’ because of the high dose hook effect. While heating at over 150°C, long term exposing to sunlight, washing and bleaching of bloodstains prevented the detecting of human hemoglobin using ‘OC-Hemocatch’, contamination of blood with various body fluids did not affect it. Furthermore, ‘OC-Hemocatch’ detected human hemoglobin from old bloodstains stored for 15 years at room temperature when 5% ammonia was used for extraction. These results demonstrate that ‘OC-Hemocatch’ can be effectively applied to forensic identification of human blood.

A recent meta-analysis of dampness in homes has shown that dampness and mold in indoor environments are factors in approximately 30-50% of all respiratory and asthma-related health ailments. Although the specific indoor dampness factors related to such issues have yet to be fully explored, there are clear and urgent needs for improved architectural techniques and optimized occupant behavior patterns that can prevent or eliminate excessive dampness inside buildings. Furthermore, if the underlying structures linking dampness to adverse health effects could be more closely estimated through epidemiological surveys, prevention methodologies for serious problems related to indoor dampness might be discovered. With these points in mind, we previously proposed a home dampness estimation method based on occupants’ self-reported answers to questions regarding indoor dampness during winter. This resulted in an indoor dampness index covering a range from 0 to 24 that classifies houses into four ranks, with those in Rank 4 presenting the most serious dampness-related problems. To clarify the relationship between home dampness levels and indoor environmental quality, another questionnaire survey was conducted and several physical environmental items such as indoor temperature, humidity, and microbial flora from floor dust were measured in 119 detached East Japan houses during the winter season. Herein, we describe the surveyed results and the distribution of the dampness index. The questionnaire also included child health-related symptoms that show onsets within 3 months, and the prevalence of each symptom is presented in relation to each dampness index rank. The characteristics of indoor temperature and humidity resulting from home dampness levels were also clarified by comparing the dampness index and measured results of these physical items. Analyzing the survey results, we found that the prevalence of nasal- and eye-related symptoms increased approximately in tandem with the dampness index ranking. In particular, more than 50% of the children residing in Rank 4 homes reported nasal problems, and there was a high prevalence of throat and skin symptoms in Rank 3 homes. However, despite these values, there are still no clear links between the dampness index and the reported health-related symptoms. Next, the statistical values of temperature, relative humidity, and the humidity ratio during evening time in living rooms and bedrooms were analyzed for each dampness index rank. To test the significance of these associations, Kruskal-Wallis testing was performed to determine whether the samples in each dampness index rank originate from the same distribution. Moreover, the significant differences among each rank’s samples were tested in multiple comparisons. As for temperature results, no significant association was found among the dampness index ranks. This presumes that living room temperatures are affected by heating behaviors at the time of occupancy. On the other hand, both the relative humidity level and the humidity ratio were found to be strongly associated with the dampness index rankings; with higher humidity levels in the living room and bedroom presaging higher dampness index ranks. In addition, the relative humidity and humidity ratios in Rank 2, 3, and 4 living rooms were significantly higher in comparison with Rank 1 living rooms, while the median relative humidity values in Rank 4 living rooms and bedrooms were around 50% and 70%, respectively. Significantly, the humidity ratios in Rank 4 homes were found to be the highest among the surveyed houses and it was expected that these houses had severe environmental problems related to indoor dampness.

本稿はプロミスキーパーズという名称のキリスト教系ホームレス支援NPOのケーススタディを通して日本のFaith-Related Organization の志向性に焦点をあてる。プロミスキーパーズは活動開始当初、教会としてホームレス支援をしていたが、活動のための資源を多元化するためにNPO となった。そうすることで、プロミスキーパーズはホームレスに対して様々な支援を提供することが可能となり、沖縄で最も信頼されるホームレス支援組織となった。プロミスキーパーズは内部の結束力の強い教会を基盤にしながら、外部に開かれたNPOとして活動している。すなわち、プロミスキーパーズは結束型ソーシャル・キャピタルと橋渡し型ソーシャル・キャピタルの双方を内在させているのである。近年、「宗教の社会貢献」が社会的に学問的に要求されているが、本稿の事例は宗教の新たな社会参加のモデルを考察する一助となるだろう。

喜界島小野津方言の呼称名詞(親族呼称や呼びかけに使われる人名)は,母音の長さの交替と音調型の点で特殊な振る舞いを示す。本稿は,呼称名詞の音韻的特徴について記述した上で,呼びかけの下降イントネーションが呼称名詞の語彙的な特徴に通時的変化を及ぼしたことを主張する。本稿において提案する仮説は,呼称名詞にアクセント型の推移と長母音化の二つの連続的な変化が起こったというものである。このうち二番目に起きた変化が,最も音韻的独立性の低い助詞によって部分的に阻止されたため,呼称名詞の特殊性が生じたと考えられる。

1. Background and objectiveThis study examines the methodology of "individual scaling method" in order to value each person's vocabulary and viewpoints. "Individual scales" refers to evaluation items made by subjects' own terms. Thus, these scales are different from person to person. In the previous report, we proposed principal component analysis (PCA) method for evaluation data measured by individual scales. In this PCA method, evaluation object is regarded as observations, and individual scales of all subjects is regarded as variables. And, individual difference in vocabulary and viewpoint is described as difference in distribution of factor loadings vectors in principal component space. Therefore, it is difficult to analyze individual difference of each object. In this paper, methodology for analyzing individual differences of each object in individual scales method was studied and proposed.2. Methodology of analysisFor the above purpose, the application method of "partial score" used in the analysis method called MFA (MultipleFactor Analysis) was discussed. And the following method was proposed.1) Exclude subjects with low correlation between partial score and global score (principal component score).2) Use "standardized partial score" to analyze individual differences for each object.3) Correcting techniques for "ipsative data" may be necessary when analyzing individual or group differences between multiple objects.In addition, using "HCA (Hierarchical Component Analysis)" as the analysis method is expected to improve the performance of partial scores.3. Case studyAs a case study, a survey on positioning analysis for dental clinic was conducted. The background, purpose and method of this survey were described.4. Analysis and discussionPCA, MFA (Block-based PCA), and HCA were applied to the case study data, and the following results were obtained.1) The output principal component scores did not differ between the methods.2) HCA was the best in the performance of statistical tests for partial scores. This shows that reliability of partial score by HCA is higher than that of other methods.3) It was found that the positioning of the dental clinic is different between those who are positive for visiting dental clinic and those who are not.5. Consideration on Methodology of AnalysisBased on the results of analysis as a case study, methodology was further considered. First, as a criterion to exclude subjects with low correlation between partial score and global score , “R-square≧0.4” was proposed. Next, how to use FA and PCA properly was considered, and necessity of correcting techniques for "ipsative data" was discussed.6. Future tasks and prospectsThe future tasks are to apply the proposed method to many cases. And, using partial scores, it seems possible to analyze individual scale method data, including different objects for each person. It is also a future task to consider this method.

Gastroscopy, acidity test of gastric juice, occult blood test, X-ray examination, and histological examination were carried out in 300 cases (213 cases of men and 87 cases of women) for two years from Sept., 1960 to Sept., 1962.<br>By gastroscopy 16 cases were diagnosed as normal, 207 cases as chronic gastritis, 66 cases as gastric ulcer, 9 cases as gastric carcinoma, and 2 cases as gastric polyp.<br>Superficial gastritis and hypertrophic gastritis were frequent in persons of younger age, and so were atrophic gastritis in forties, gastric ulcer in thirties, and gastric carcinoma in persons of advanced age.Gastric ulcer and superficial, hypertrophic gastritis were relatively frequent in men, while atrophic gastritis in women.<br>In many cases gastric carcinoma was accompanied by atrophic gastritis, gastric ulcer by superficial gastritis and atrophic gastritis, duodenal ulcer by superficial and hypertrophic<br>gastritis, and cholecystiasis by gastritis.<br>Most of patients complained of epigastric pain.<br>The rate of positive occult blood test of feces was high in cases of gastric carcinoma, but comparatively high in those of normal stomach and chronic gastritis.<br>Zero acidity was frequent in cases of gastric carcinoma and positive acidity in those of gastric ulcer. In many cases of chronic gastritis which showed atrophic degeneration, acidity tended to decrease. It was thought that in cases of gastric carcinoma and gastric ulcer the accompanying gastritis predominated their inherent degeneration and greatly affected the acidity. In many cases of gastric carcinoma the occult blood test of gastric juice was positive, and especially positive in all the cases of zero acidity. This test was positive in only a few cases of chronic gastritis and in a relatively few cases of gastric ulcer.<br>Diagnosis with X-ray examination coincided well enough with that of gastroscopy. In some of cases which were diagnosed as normal stomach and gastroptosis, chronic gastritis was found by gastroscopy. Atrophic degeneration was seen more frequent in gastroptosis than in normal stomach.<br>Diagnosis with gastroscopy was consistent with that with operation and histological examination.

We investigated the RGB and XYZ components of the natural colors (two cherry blossoms, i.e., Someiyoshino and Youkou, and the emission of Heike-firefly), and the physiological effects on Japanese and foreign people were compared. The natural colors were digitally measured as RGB colors, and then they were used as color stimuli. The psychological effects were investigated by administering a questionnaire, which was based on the Semantic differential (SD) method. From the results of the questionnaire, the degrees of expression for the natural colors were quite different between Japanese and foreigners. The kansei on the natural colors between Japanese and foreigners were also different in terms of psychophysical quantity and physical cognition. The results of factor analysis showed that the color of Youkou gave pleasantness to Japanese people, whereas the colors of Someiyoshino and firefly gave pleasantness to foreign people.

水道水中ハロ酢酸類9種(水道水質基準項目:3物質、要検討項目:6物質)について、前処理を必要としない直接注入- LC/MS/MS による一斉分析法を検討した。ハロ酢酸類2μg/L に高濃度マトリックス(塩化物イオン:177mg/L、ナトリウムイオン、カルシウムイオン、硫酸イオン、炭酸イオン:100mg/L、硝酸イオン:100mgN/L)をそれぞれ添加し回収率を求めた結果、9種すべてのハロ酢酸類で71~118%の回収率が得られた。また、標準液の溶媒としてtert -ブチルメチルエーテル、メタノール、エタノール及び精製水を用いて長期保存試験を実施した結果、メタノールはメチル化、エタノールはエチル化が進み、ハロ酢酸類原体の濃度が減少した。この濃度低下は、保存温度が高く、さらには混合標準液とすることで顕著であった。ハロ酢酸類は、メタノール溶液(-20℃)保存においてもメチル化反応が進むため、標準溶液に用いる溶媒はtert -ブチルメチルエーテルが最適であることを確認した。

This paper addresses the mechanical issue of a novel wheel design capable of step climbing toward more convenient utilization of assist vehicles such as wheelchairs and walkers. Despite the promotion of barrier-free environments, uneven floors with dips and depressions, thresholds, and steps have still been encountered in our daily routines. To overcome these difficulties, a step-climbing mechanism and its device are developed, allowing wheeled robots to ascend a step where its height is higher than the radius of the wheel. By applying the proposed step-climbing device into the robot, it enables potential users to minimize a physical burden during step climbing. This helps the users live independently and maintain their daily routines, not requiring caregivers and/or medical staff. What is the most important aspect from the practical point of view is how to realize the mechanism without additional wheels and linear guides. This paper describes the mechanical design by controlling axial translation in detail. By using a robotic wheelchair equipped with the proposed device, extensive evaluations are tested and analyzed.

金沢大学皮膚科で10年間に経験した成人発症Still病15症例(男性1例,女性14例,平均年齢35.8歳)について,臨床症状,治療,および予後に関して検討した.本症の特徴的な皮疹は発熱に伴い出没する痒みのない紅斑とされている.しかし,自験例の検討では,発熱に伴って出没する紅斑が4/15例(27%)にしかみられなかったのに対し,発熱と関連なく出没する紅斑が9/15例(60%)にみられた.また紅斑がみられた症例のうち6/15例(40%)は痒みを伴っていた.これらの検討からは,発熱との関連やそう痒の有無にはとらわれず,出没する散在性の淡紅色の小紅斑がStill病の皮疹の特徴と考えられた.経過の検討では,12カ月以上観察しえた14例中6例(43%)はステロイド剤の中止が可能であった.また14例中7例(50%)は減量時などに症状の再発があった.臨床経過が初発症状や検査値により推測できるかを予測したところ,皮疹が発熱や関節痛に先行して出現した6例は全例再発がなく,皮疹が発熱や関節痛と同時あるいは後で出現した群の再発率(8例中7例:88%)と比べて有意に低かった(P<0.05).今後多数例での解析は必要であるが,初発が皮疹のみで全身症状がすぐに出現してこない症例は軽症で,再発しにくい可能性があると考えられた.
