Corrosion of steel structures is unavoidable and the structural performance decreases dramatically due to the corrosion. As a repairing method for corroded steel members, bonding carbon fiber sheets with resin had been developed. The purpose of this study is to propose the flexural strengthening method for steel members by using CFRP （carbon fiber reinforced polymer） strand sheets. In order to clarify the stiffening effect and the debonding characteristics of CFRP strand sheets, and to optimize the strengthening design specifications, the flexural tests using high tension steel beams strengthened with CFRP strand sheets are performed. Two cases of experiments are carried out. In Experiment 1, the result from previous research is reflected in the strengthening design. Moreover in Experiment 2, the debonding characteristics obtained from Experiment 1 are reflected. As a result, it was clarified that CFRP strand sheets have stiffening effect equivalent to the theoretical value and its debonding property is practically high enough when FRP （fiber reinforcement polymer） sheets have an appropriate bonding length.

Objective: The present study compared results on the Wechsler Adult Intelligence Scale-Revised (WAIS-R) among adult patients with attention-deficit/hyperactivity disorder (AD/HD) and those with Asperger’s disorder (AD). Method: WAIS-R results were compared between 16 adults with AD/HD (8 men and 8 women;mean age, 33.81 years;mean full-scale IQ, 101.5) and 15 adults with AD (12 men and 3 women;mean age, 30.93 years;mean full-scale IQ, 104.6). Results: Verbal IQ was significantly higher than performance IQ in the AD group. Among various subtests, scores were the highest for similarities in the AD/HD group and for block design in the AD group. Picture completion test scores were the lowest scores obtained in both groups. A comparison of subtest scores between the AD/HD and AD groups showed scores for information to be significantly higher in the AD group than in the AD/HD group. Conclusions: Our results suggest that there are no differences in verbal IQ, performance IQ, and full-scale IQ scores (except for scores on the information subtest) among adult patients with AD/HD compared with adult patients with AD.

Adequate vegetable intake is important in reducing the risk of lifestyle-related diseases;however, intake amongst young Japanese adults is poor. This study aimed to assess the effect of daily intake of a commercially available vegetable juice on nutritional status and metabolic syndrome-related markers in healthy young adults. Fifty-one healthy adults (14 men, 37 women), age 20 - 22 years were recruited, and their food and nutritional intake was surveyed using an FFQ based on Food Groups. Subjects were divided into either a control group, who were not administered vegetable juice, or an intervention group, who consumed 200 mL vegetable juice daily for 2 months. Anthropometric data, serum carotenoid concentrations, blood and urinary parameters were measured at baseline and at 2 months. The average intake of vegetables in all subjects at baseline was approximately 140 g/day, less than half the dose recommended by the Japanese government. Total serum carotenoid concentration in the intervention group doubled from baseline after 2 months. In particular, serum concentrations of α-carotene, β-carotene, and lycopene were increased. In the intervention group, 24-hour urinary potassium excretion increased significantly, and 24-hour urinary sodium to potassium ratio decreased significantly. Waist circumference and systolic blood pressure also decreased significantly. Daily intake of a commercial vegetable juice for 2 months improved nutritional status in young adults with inadequate vegetable intake, shown by improved serum carotenoid and urine potassium levels. In addition, intake of vegetable juice may be beneficial in reducing the risk of metabolic syndrome.

＜正＞Introduction Cyanobacteria are the most primordial oxygenic photosynthetic organisms and have a peripheral antenna, phycobilisome （PBS）. The most primordial cyanobacterium, Gloeobacter violaceus PCC 7421, has a bundle-like PBS, which is different from other cyanobacteria that have hemi-discoidal PBSs. We examined energy transfer dynamics in the bundle-like PBS by means of picosecond time-resolved fluorescence spectroscopy.

The efficacy of milnacipran for the treatment of ADHD symptoms in adult Asperger’s disorder patients was examined. Fifteen consecutive adult Asperger’s disorder patients with ADHD symptoms were treated with milnacipran for 8 weeks. Global Assessment of Functioning (GAF) and Conners’ Adult ADHD Rating Scales Objective Screening Version (CAARS-O-SV) were used for the assessment. The mean GAF scores in the 15 patients improved significantly. Inattention, inattention + hyperactivity/impulsivity and ADHD index in CAARS-O-SV were also significantly improved. Milnacipran might be useful for ADHD symptoms, exerting its effects by increasing serotonin and noradrenaline activities in Asperger’s disorder.

Regional cerebral blood flow (rCBF) studies of major depression have yielded variable results. The present study employed a longitudinal observation method to measure rCBF every 3 months during treatment. Thirteen patients with major depressive disorder underwent single-photon emission computed tomography (SPECT) with 99mTc-HMPAO three times over a 6-month period. rCBF was analyzed with the Statistical Parametric Mapping. The findings were compared to scans from 14 normal control subjects. Depression symptoms were rated using the Hamilton Rating Scale for Depression. At baseline, the main regions with lower rCBF compared to controls were the middle and inferior frontal gyri, superior temporal gyrus, and cingulate cortex. Three months later, despite significant improvement of depressive symptoms, decreased rCBF was observed in the same regions, but to lesser extent. At 6 months, depressive symptoms showed continued improvement, and rCBF in the superior temporal gyrus increased up to control levels, but rCBF in the temporal pole, cingulate, and inferior frontal gyrus remained low. The results of the present study suggest that there might be time- and state-dependent differences in rCBF recovery in patients with major depression.

Objective: To identify the patterns of tuberculosis (TB) notification rates in Phnom Penh and examine their relationships with the population density, socioeconomic, residential and occupational characteristics. Methods: The numbers of total TB and smear-positive pulmonary TB cases reported between January 1, 2010 and December 31, 2012 in Phnom Penh were counted for 76 communes in Cambodia according to TB registration records filed under the national TB programme. Population, socioeconomic, residential and occupational characteristics for the communes were obtained from the 2008 General Population Census of Cambodia. The following indicators were developed for individual communes: smear-positive pulmonary TB notification rate (SPTB-NR) (per 100,000 population, in 36 months), population density (per km2), socioeconomic indicators, residential characteristics and occupational characteristics. Geographic patterns of these indicators and characteristics were analysed using ArcGIS. Associations between SPTB-NR and characteristics were analysed. Results: A total of 4102 TB cases were reported in 36 months, including 2046 SPTB cases. SPTB-NR for Phnom Penh was 135 cases per 100,000;median SPTB-NR by commune was 100. SPTB-NR was higher in outlying areas than in city centre communes;population density was high in the centre and low in the outlying areas. SPTB-NR was associated with larger percentage of household members per room (PR: 2.81, 95%CI: 2.68 - 2.93), percentage of population resident in the same commune Conclusions: The SPTB-NR in Phnom Penh did not follow the pattern of population density. Socioeconomic, residential and occupational characteristics by commune were associated with SPTB-NR. Development of prevention and control programmes by considering commune level characteristics is encouraged.
