kn-title=Automatic Mesh Generator For 3-Dimensional Finite Element Analysis
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this paper is to propose new automatic mesh
generator for the finite element analysis of threedimensional structures consisted of plates and beams.
The strategy of the proposed one is as followings; Firstly, subdivide the structure into two-dimensional and one-dimensional structural components. Secondly, generate mesh pattern for each of them, and finally combine them so that they reconstruct the original configuration. By using the proposed method the modeling of, for example, steel bridge structures for Finite Element Analysis is easily and also fastly completed. Some examples of the application of the proposed method are presented, and from the examination of the results further important informations for the design of better method are also given in this paper.

kn-title=Some Remarks on Finite Element Mesh Modeling of Crack-Tip Area
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=The aim of this paper is to present some remarks on the
arrangement of finte element mesh modeling of the area
adjacent to the crack-tip which locates in two-dimensional
area. Since the stress distribution near crack-tip is singular, the arrangement of mesh pattern and the selection of mesh type in the crack area govern the accuracy of the solution. This paper gives some informations on the arrangement of finite elements in the area which are obtained through numerous number of numerical experiments. And the effectivity of Zooming Technique for stress analysis is clarified through the
experiments.

en-abstract=
kn-abstract=Car ownership in households is analyzed by disaggregate behavioral modeling technique. Two models are built to analyze characteristic features of car ownership. The results are (1) The number of driver licenses in a household is, as a matter of course, most influencing on car ownership and multi-ownership. (2) Family size is the second most influencing. (3) Utilily obtainable by owning second or third car is higher in the household of primary industry than that of the other industry. (4) Inclination of household to be car owner is stronger in a sparsely inhabited zone than in a densely inhabited.

kn-title=Influence of Sewage Treatment System on Water Quality in Kojima Lake
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=This study dealt with the characteristics of hydrodynamics of Kojima Lake and the influence of a regional sewage treatment system in construction on the lake. Clockwise and anticlockwise circulations are caused by seasonal winds in summer and winter, respectively. The distribution of a conservative material continuously discharged off the shore of the sewage treatment plant is scarcely affected by seasonal winds and river discharges. The sewage treatment system improves the water quality of the lake except T-N.

kn-title=Depth Dependency of Hardness Change of Ti-Mo Alloys
en-subtitle=
kn-subtitle=
en-abstract=
kn-abstract=We investigated the effects of resolved interstitial oxygen or nitrogen atoms and of quenched-in strain on the hardening of the single crystals grown from molten Ti-14 and 20wt pct Mo alloys. The aging treatment at 623K in atmosphere much more increased in the hardness of specimen surface than that in argon atmosphere. The quenched-in compressive stress enhanced age hardening due to omega formation. We surveyed in detail the hardness changes toward the center of plate-shaped single crystal.
