The purpose of this paper is to show that in a time of dramatic social change and progress in information communications technology, surveys and analysis were used to identify residents' lifestyles and their views and attitudes toward public libraries.
Two series of surveys were conducted in suburban/rural cities of Japan in 2004 and 2006. The first survey was across all local residents, and the second among library users. The results of these surveys were analyzed in depth, and different lifestyle groups were identified. Library use by each of these groups was investigated in detail.
The findings demonstrate that those who positively appreciated the various benefits of the public library tended to be frequent/regular visitors and to belong to the “Group of ‘actively striving’” and the “Group of ‘respecting others’” in the 2004 survey, and similar types of group in the 2006 survey. In addition, the 2006 survey also showed that the visitors include those who were not necessarily conscious about library services, and 10 per cent of the respondents were not much interested in them at all.
The results demonstrate that the libraries acquire new user groups according to their service innovations. However, it was found that people have already started to utilize search engines on the internet, regardless of the presence/absence of the corresponding service in the library to acquire various types of information.
This paper re‐examines the traditional understanding of the user profile of public libraries, and demonstrates a tool to help identify changes in use and users.

The purpose of this paper is to present a comprehensive review on development and future trends in zinc oxide thin film transistors (ZnO TFTs). This paper presents the development of TFT technology starting from amorphous silicon, poly-Si to ZnO TFTs. This paper also discusses about transport and device modeling of ZnO TFT and provides a comparative analysis with other TFTs on the basis of performance parameters.
It highlights the need of high–k dielectrics for low leakage and low threshold voltage in ZnO TFTs. This paper also explains the effect of grain boundaries, trap densities and threshold voltage shift on the performance of ZnO TFT. Moreover, it also addresses the challenges like requirement of stable p-type ZnO semiconductor for various electronic applications and high value of ZnO mobility to meet growing demand of high-definition light emitting diode TV (HD-LED TV).
This review will motivate the readers to further investigate the conduction mechanism, best alternate for gate-dielectric and the deposition technique optimization for the enhancement of the performance of ZnO TFTs.
This is a literature review. The technological evolution of TFT in general and ZnO TFT in particular is presented in this paper.
