Model performance of a regional-scale meteorology – chemistry model (NHM-Chem) has been evaluated for the consistent predictions of the chemical, physical, and optical properties of aerosols. These properties are essentially important for the accurate assessment of air quality and health hazards, contamination of land and ocean ecosystems, and regional climate changes due to aerosol-cloud-radiation interaction processes. Currently, three optional methods are available: the 5-category non-equilibrium, 3-category non-equilibrium, and bulk equilibrium methods. These three methods are suitable for the predictions of regional climate, air quality, and operational forecasts, respectively. In this paper, the simulated aerosol chemical, physical, and optical properties and their consistency were evaluated by using various observation data in East Asia. The simulated mass, size, and deposition of SO42- and NH4+ agreed well with the observations, whereas those of NO3-, sea-salt, and dust needed improvement. The simulated surface mass concentration (PM10 and PM2.5) and spherical extinction coefficient agreed well with the observations. The simulated aerosol optical thickness and dust extinction coefficient were significantly underestimated.

Many parts of work in libraries depend on a wide range of IT knowledge. Appropriate planning of IT training programs is necessary to improve information security, efficiency, and quality of daily work. This article lists possible kind of IT knowledge and describe how they can be applied to working areas.

We have investigated the electronic structures of n- or p-type doped ZnO based on ab initio electronic band structure calculations. We find unipolarity in ZnO; n-type doping using Al, Ga or In species decreases the Madelung energy while p-type doping using N species increases the Madelung energy, in addition to causing substantial localization of the N states. Codoping using reactive codopants, Al, Ga or In, enhances the incorporation of N acceptors in p-type codoped ZnO. We find the delocalized states of N for p-type ZnO codoped with N and Al (Ga).

This paper describes the development of a data convertion tool. It aims to simplify data converting processes, which consist of reading data, converting data, filtering data, and outputting the resulting data. Every phase of converting data can be easily customized by writing plug-in modules with simple rules.

Author name is an important access point for academic information. But academic information systems do not always control the author name. Above all, the format of author names varies from system to system. We must resolve this problem to develop an institutional repository (NAGOYA Repository). Our plan is to develop a system of resolving author name in order to connect systems with one another. This resolution system links existing systems via author name with minimum customization. This paper describes our approach, outline of the system and the remaining issues.
