High Efficiency of Dye-Sensitized Solar Cells

复旦学报（自然科学版） 2005年第5期44卷 715-716页

Much attention has been paid to the development of dye-sensitized solar cells (DSCs) during the past decade. In general, a DSC comprises a nanocrystalline titanium dioxide (TiO2) electrode modified with a dye fabricated on a transparent conducting oxide (TCO), a platinum (Pt) counter electrode, and an electrolyte solution with a dissolved iodide ion/tri-iodide ion redox couple between the electrodes. Although a DSC using black dye with high efficiency of 10.4%, which was measured by NREL(U. S. A. ), was reported by Graetzel et al. [1], the efficiency of DSCs should be further improved for practical use in comparison with silicon solar cells.

Relationship between Self-Perceived Age and Social Activity in Older Japanese Adults: The KAGUYA Study

Health 2018年第11期10卷 1459-1473页

Youthful feelings were shown to have a positive effect on the mental and physical conditions of the elderly. On the contrary, elderly people whose self-perceived age is older than their chronological age were shown to experience negative health outcomes. This study investigated whether the self-perceived age (younger or older) relative to chronological age promotes social activity. The baseline data acquired from 3094 older adults as part of the Keeping Active across Generations Uniting the Youth and the Aged study was used in the current study. The participants completed a questionnaire that solicits information pertaining to sociodemographic factors, felt age, self-rated health, physical activity, depression, disease burden, fall history, fear of falling, level of instrumental activities of daily living (IADLs) and social activity. The discrepancy between felt age and chronological age was defined as the self-perceived age. Self-perceived age was calculated by subtracting the participant’s chronological age from the felt age, and the score for the difference was divided by the chronological age. The Japan Science and Technology Agency Index of Competence was used to evaluate social activity. Regression analysis results revealed that a younger self-perceived age was associated with higher social activity after controlling for sociodemographic factors, self-rated health, depression, physical activity, disease burden, level of IADL, fall history and fear of falling. Fall history was significantly associated with higher social activity in young-old participants (65 - 74 years) (p = 0.014) but not in old-old participants (>75 years). This study suggests that a younger self-perceived age in older adults would lead to a high-level living function. This finding may provide useful information for interventions aimed at the promotion of health and/or the prevention of frailty.

第十五届国际光伏科学与工程大会

The improvement of cell performance of dye-sensitized solar cells (DSCs) was investigated by means of haze factor of TiO electrodes. It was found that the incident photon to current conversion efficiency is effectively improved by the increase of the haze factor of TiO without loss of open circuit voltage. The highest efficiency of 10.4% (aperture area: 1.004 cm) and 10.8% (aperture area: 0.2227cm) confirmed by the public test center (AIST) was achieved.

Association of Adolescent Smoking with Maternal Smoking

引用

Open Journal of Preventive Medicine 2014年第5期4卷 347-353页

作者： Hideko Morikawa Manabu Akahane Masahiro Yamada Tomoaki Imamura Department of Public Health Health Management and Policy Nara Medical University School of Medicine Nara Japan katsuragi Public Health Office and Healthcare Center Nara Prefectural Government

Objective: To determine the effect of family smoking habits on adolescent smoking experience for information for anti-smoking strategies. Subjects and Methods: We analyzed data from 4776 junior high school students and 5047 high school students responding to the “Survey on Prevention of Life-Style Related Diseases of Children” conducted in Nara Prefecture of Japan in 2004. The chi-square test determined the odds ratios (ORs) for smoking experience rates of the two groups of students according to the smoking habits of their fathers, mothers, older brothers, and older sisters. Logistic regression analysis was also performed for smoking experience according to school year, sex, and family smoking habit. Results: The OR for smoking in junior high school students with a father as the only smoking family member against all other cases was 0.60, and the OR with a mother as the only smoking family member was 2.50. The OR with a smoking father against cases with no smoking family members was 1.23, and the OR with a smoking mother against cases with no smoking family members was 3.50. The OR for smoking in high school students with a father as the only smoking family member against all other cases was 0.76, and the OR with a mother as the only smoking family member was 2.66. The OR with a smoking father against cases with no smoking family members was 1.59, and the OR with a smoking mother against cases with no smoking family member was 3.26. All these ORs showed significance. Conclusion: Maternal smoking was associated with a particularly high risk of smoking experience in junior high and high school students. Prevention of maternal smoking should be given high priority to reduce smoking rates in adolescents.
