Background: During and after the Fukushima nuclear disaster (FND), many parents were concerned about the effects of radiation on the health of their children. Purpose: To clarify the factors that influenced general workers living with children and the effect of child age groups in implementing preventive behaviorsagainst radiation following the FND. Materials and Methods: A descriptive study of preventive behaviors among general workers was carried out 3-5 months after the nuclear disaster. The subjects were 1,394 regular workers, who took part in radiation seminars run by the Fukushima Occupational Health Promotion Center between July and September, 2011. In total, 1,217 responses were submitted, of which 1,110 were eligible for the present study. This anonymous questionnaire survey inquired about the presence and age of children in the household and about radiation preventive behavior implemented after the FND. The contribution of each variable was assessed by logistic regression analysis. Results: General workers in Fukushima who lived with younger children performed more preventive behavior against radiation during and after the FND. In particular, both location-related and daily routines were practiced significantly more frequently (p<0.01) by workers living with a child in the age ranges of 0-6 (8 of 10 items) and 7-12 (5 of 10 items). Conclusions: This is the first study to assess the positive association between living with children by age group and increased preventive behavior against radiation implemented by general workers after the FND.

Healthcare is increasingly becoming a distributed service involving stakeholders and resources who may be physically far from each other. But privacy and security are potential problems. Patient’s data should be available irrespective of their location, but only to authorized person. Not only that, the relationship between the person under observation and other related people, are different and the security and other characteristics concerning the data may also differ accordingly. In this paper we propose a system where an overlay network can be built in an ad hoc basis and links between different entities will be established according to the social relationship between the object person and the person at the other end and the situation of the observed person. Unlike traditional 24-hrs monitoring system, we argued that an ondemand, requirement oriented system will be beneficial for efficient resource utilization, specially in wireless communication.
Outdoor performance evaluation of photovoltaic modules using contour plots
Takashi Minemoto,Hiroaki Takahashi,Yasuhito Nakada,Hideyuki Takakura 한국물리학회 2010 Current Applied Physics Vol.10 No.2
The impact of environmental parameters on different types of Si-based photovoltaic (PV) modules (single crystalline Si (sc-Si), amorphous Si (a-Si) and a-Si/ microcrystalline Si (μc-Si)) which have different spectral responses were characterized using contour plots. The contour plots of PV performance as a function of module temperature and spectral irradiance distribution were created to separate the impact of the two environmental parameters. The performance of the sc-Si PV module was dominated by the module temperature while those of a-Si and a-Si/lc-Si ones were mainly influenced by the spectral irradiance distribution. Furthermore, the frequency of outdoor conditions and the reliability of the contour plots of the PV performance were discussed for the evaluation of PV modules by means of energy production.

An expert network administrator is not always stationed as disasters happen. In that case, it is desirable that a novice administrator is capable of taking part in network recovery operations as well. In this paper, aknowledge-based network management system in emergency situations is presented. We use the Active Information Resource based Network Management System (AIR-NMS) to relieve the human administrator from parts of her management tasks and present an interface that remotely can control this management system. The effectiveness of the system is demonstrated by experiments using a prototype system.
Interaction between ultrafine ceria particles and glycine

An ultrafine ceria powder of 15 nm equivalent spherical particle diameter was dispersed at 2 vol% solid in aqueous solutions with and without glycine (H2NCH2COOH) of 0.05-5.0 mass% against ceria. The addition of glycine increased the zeta potential of the ceria toward positive values in acidic suspensions. The phase separation of ceria suspensions due to the decreased repulsive energy with decreasing particle size, was suppressed by the steric stabilization effect of the adsorbed glycine. No significant influence of the glycine addition on the zeta potential and phase separation of the basic suspension was measured.

Influences of clearness index (Kt) and air mass (AM) on both the sunlight and the outdoor performance of photovoltaic (PV) modules were analyzed. The Kt and AM strongly affect the intensity of solar irradiation and spectral irradiance distribution. In this study, the impacts of Kt and AM on an index for spectral irradiance distribution of average photon energy (APE) are analyzed using a contour maps and then the impacts of the environmental factors on the outdoor performance of single crystalline Si (sc-Si) and amorphous Si (a-Si) PV modules is discussed. As the result, it was found that APE increases with decreasing the Kt and AM. Furthermore, it was found that the outdoor performance of a-Si PV modules strongly depended on APE compared to sc-Si PV modules. Thus, APE can be estimated from the contour map with the Kt and AM.

We report the results of Sb nuclear quadrupole resonance (NQR) measurements on the filledskutterudite CeFe4Sb12 synthesized under high pressure (HP) and compare them with those forthe sample synthesized under ambient pressure (AP) to understand the influence of the Ce-sitefilling fraction. The NQR spectra for the HP sample are much sharper than those for the APsample, suggesting that the Ce filling fraction is higher. Also, the nuclear spin-lattice relaxationrate 1/T1 follows an exponential decrease 1/T1 ∝ exp(−Δ/kBT), with the gap being Δ/kB = 270K at temperatures above 100 K, which is larger than that for the AP sample. This result suggeststhat the c-f hybridization is enhanced by increasing the Ce-site filling fraction.
