Author carried out this study for clarifying topographical characteristics and verifying scale of natural phenomenon in the places indicated by the “Shizensaigaidenshohi” (monument of natural ...disaster). The followings are the major results.1) Clarification of topographic characteristics where a “Shizensaigaidenshouhi” stands or indicates.Most of the place where “Shizensaigaidenshouhi” (monument of natural disaster, simply referred to as “the monument” in this article) stands or indicates, locates not only in very low areas (e.g. flood plain), but also in a little bit higher areas (e.g. natural levee). This is because the monument building was not reasoned by heavy rainfall or flood itself, but by the damage of lives or properties which exist in higher areas.2) Verification of scale of natural phenomenon which brought disaster where a “Shizensaigaidenshouhi” stands or indicates.Past flood depth inferred by the description of the subject monuments was slightly low or equal to that estimated by modern hazard map. In early and middle of the 20th century, many flood disaster happened and the relevant monuments were built thereafter, but in the late 20th century, the number of severe floods which recorded in the monuments decreased. However, frequency of heavy rainfall is increasing recently. This suggests flood disasters likely to be recorded in the monuments would occur again in the near future.These results show that location of a “Shizensaigaidenshouhi” stands or indicates prefers a little bit higher areas as people lives more in such areas compered to lower land and also show that past flood depth inferred by the description of the subject monuments was compatible with that estimated by modern hazard map.Map symbol “Shizensaigaidenshohi” is recently introduced to the basic topographic maps, and the new topographic maps therefore provide people with new map reading experience, which might raise people's awareness of disaster prevention as existence of “Shizensaigaidenshohi” is deeply relating to topography.
新たに発生する崩壊や地すべりの地形的特徴を抽出するためには，崩壊や地すべり発生前の地形データを用いて地形解析を実施する必要があるが，崩壊や地すべりが発生する前の地形データは取得されていないことが多い．一方，衛星画像は定期的に撮影されているため，衛星画像から作成された地形データなどを崩壊前の地形データとして活用できる可能性がある．本研究では，衛星画像から作成された地形データとオルソ画像を地形解析などに活用できるか判断するために，航空レーザ計測結果と比較した．その結果，平野部は地形データおよびオルソ画像ともに2 m 程度の残差になることが分かった．一方，山間部は2 m程度の残差になる箇所，9 m程度の残差になる箇所が存在することが分かった．
This study aims to clarify the spatial composition and elements of traditional Korean Byeol-Seo Gardens through the field survey and the GIS analysis of topographical characteristics. The field ...research and survey were carried out on August and November in 2014 and November in 2015 at 9 gardens in Gwangju, Damyang region：MyunAngJeong, SongGangJeong, YeongGyeJeong, MoonIlJeong, KwanSooJeong, SikYoungJeong, HwanBuckDang, ChiGaJeong and MyuongOkHeon. Through creating the original contour maps by combining the field survey results with GIS data，the following aspects are consequently observed on the 9 gardens. (1) Byeol-Seo is considered to have spatial composition to be aware of the view from the Pavilion. (2) Topographical characteristics make spatial composition in Byeol-Seo and fall into two major categories. While prior researches focused on the meaning and philosophy of the gardens, this study, involving the quantitative analysis, elucidates the style of the spatial composition. This kind of analysis could be the basis of recognizing the morphological characteristics and the meaning of the spatial design of the traditional garden.
Titanium carbide (TiC) coatings have been deposited on steel using the pulsed electrode deposition (PES) technique. Different experimental parametric conditions were used in the deposition process. ...Microstructural and chemical characterisations of the coatings were performed using electron microscopy and X-ray diffraction techniques. Pulsed electrode technique produced hard coatings, which are commonly defect and crack free. Small TiC and Fe

C particles were randomly distributed in a Fe matrix without any preferred crystallographic orientation. The relationships between the microstructural properties and the deposition processing conditions were also explored.

In order to extract high-quality topographic characteristic lines,based on contour lines constrained Delaunay TIN,two employed methods of extracting the topographic characteristic lines are proposed ...in this paper.The first method is calculating the value of the turn angle, curvature and the shape index of contour vertex firstly,and then is to determine the threshold value according to the corresponding characteristic points set,with the rules the selected characteristic points will be connected to topographical lines .the second method is to take into account that Delaunay triangle is a triangle in 3-D space and calculate the flow direction of each small triangle at first,and then combination relations of the flow direction according to each two adjacent triangles of the public side is classified,the topographic characteristic lines are extracted according to the different edge types finally.The similarities and differences are compared through the experimental results,the existing differences is addressed in detail at last.
This study aims to clarify the topographical characteristics of the Castle-mountains which are placed in the territory of Japanese Castle-Towns. From the analysis of scale of the Castle-mountains, we ...obtained the following conclusions;(a)The Castle-mountains can be devided into the two types. One of them is the solitary mountain type, the other is the part of wide hill type. The former type can be devided into the two more types, the natural topographical type and the artificial topographical type. On the other hand, the latter type belongs to the natural topographical type. (b)We obtained the suitable scale such as hight and width of The Castle-mountains, which are belong to the natural topographical type. (c)The lower Castle-mountains placed near the coasts, lakes, wide rivers, and so on. (d)Many of the higher Castle-mountains were not used for the housing place.
