This study was conducted to propose a new "Statistical Indicators of Libraries for the Disabled (SILD)" to collect objective and reliable data from such libraries. The previous researches and related literature were reviewed to compare current national statistical indicators. The draft of a new SILD, which was based on the current SILD, was made by deriving from countable factors at the library. These were selected from various parts of the library sectors, such as the library-related laws, library standards, evaluation indices of library service for the disabled, and statistical indicators of libraries for the disabled from IFLA, ISO, and other major countries. The draft was compared to the current SILD. The draft was then reviewed by five librarians and on-site experts working at the library for the disabled to see if they have any comments on each item of the draft. The new SILD is composed of 26 items in seven categories, and it can be used in understanding the present situation of libraries for the disabled.

The problems associated with the synthesis, characterization and application of $SnO_2$-Au nanocomposites for the optimization of conductometric gas sensors have been discussed in this report. Nanocomposites have been synthesized on the surface of $SnO_2$ films using successive ionic layer deposition(SILD) method. It has been shown that the proposed approach to surface modification of metal oxide films is an excellent method for the optimization of the operating characteristics of $SnO_2$-based gas sensors, being developed for the detection of reducing gases as well as ozone.

study aims to derive a rational method for the analysis of the farm silo supported on an elastic foundation in which it is assumed that the reaction pressure of the soil at a point is proportional to the deflection at that point. In order to investigate the effects of an elastic foundation on the behaviour of the structures on it, the analysis of the farm silo resting on an elastic foundation was compared with the solution that the ground support may be assumed uniform (which was obtained from part I of this paper). To calculate the deformation of an elastic foundation, Boussinesq's solution which allows an interaction of the various parts of ground was adopted. In this case, the foundation was treated as a superparametric element additionally. In the evaluation of an element stiffness matrix, Gauss quadrature' was used. In above numerical integration, 3-point rule for the farm silo wall and the footing was introduced and 2-point rule for the evaluation of a reaction between the footing and the elastic foundation was adopted. The stresses of a farm silo on an elastic foundation were smaller than those which the distribution of contact pressure between the footing and the soil is assumed uniformly. Since the differences of stresses were remarkable in PS structures than RC structures, it is desirable that designers take into account the effect of an elastic foundation for the case of PS structures. It can be noted that while the effect of an elastic foundation was more conspicuously observed in near of the ground, the value of stresses at far from the soil was little affected by an supported soil.
