This study aims to investigate new design method rooted in the history and culture of a region through photogrammetry and the reconstruction of shapes as an expansion of the possibilities of using photogrammetric technology, which has advanced rapidly in recent years. Specifically, as an example of something rooted in local history and culture, we focused on Maruko-bune, which were developed as the boats unique to Lake Biwa in Japan but are no longer built or used. We measured the Maruko-bune using photogrammetry and constructed its 3D model. We then attempted to design architecture by decomposing and reconstructing the shape of the 3D model. As a result, we found that the photogrammetry and 3D modeling technologies have reached the point where the shape of the Maruko-bune can be measured and reproduced by photogrammetry and 3D modeling using software and a smartphone camera that can easily be used without special calibration by architects and designers who are not experts in photogrammetry, and its curves and surfaces can be used for architectural design.

 Currently, the construction industry produces significant amount of waste which generates more than 30% of the total industrial waste in many European countries. The large proportion of material waste generated in relation to materials consumed shows how waste has been unsustainably treated today. In general, this poor performance is due to dynamic and diverse characteristics of construction processes that cause inefficiency of resource use. Improvement in this area has been sought through various ways. In this respect, the use of 4D-CAD for efficient resource management and control is an area with great potential that has not been explored extensively. Current applications have shown positive results. For instance, the optimal install timings of building elements in construction can be suggested by connecting the construction process with digital objects to automate project visualization by means of animation. Thus, the potential for identifying inefficient planning solutions increases and improvement can be suggested. In addition, project progress can be monitored and managed through the whole construction process by comparing planning with as-build,
 In this study, 4D-CAD was adopted for demolition project planning. In this respect, process simulation was used as an additional support to decision-making that is often reliant on experience. For that, the volume of generated waste and the optimal timing of resource movement were estimated quantitatively with 4D-CAD. Blender, a free 4D-CAD software, was used to develop an impact simulation tool for demolition projects. Physics and game engines were used to automatically simulate demolition in accordance with physics laws. In addition, Python programming was used in the development of a Graphical User Interphase (GUI). Simulation results for the time-lapsed impact change from two variables; i) machine use and ii) waste generation. Animation recorded in simulation is also useful for better understanding of users as a visual aid.
 The testing of the tool involved the simulated demolition of a five-story building model created through BIM. Variables assessed included machine productivity for different demolition strategies and time-lapse change of waste generated. Time-lapse results of machinery productivity reveal the (in)efficiencies of different demolition processes. Waste generation data is classified by original (material) types and location; Waste distribution and purity levels are displayed on a demolition site map that forms the basis of a multi-factor waste recovery plan (e.g. machine transportation routes, collection order and timing). This process supports the definition of waste collection methods with increase purity levels and waste recovery rates. Limitations of the research includes the use of a simplified demolition method (e.g. single demolition machine and free-fall collapse).
 In summary, the aim of this research is to enhance the recycling levels of demolition waste within construction. For that purpose, a simulation tool was developed to estimate and qualify waste from building demolition using BIM enabled 4D-CAD combined with physics and game engines. The studied variables were machinery impact and waste output within alternative demolition processes. In addition, Waste Distribution Maps (WDM) are generated to support decision-making. This research represents a significant advancement in applied computing for building demolition waste recycling and notably improves the quality of information available in the definition of building demolition strategies. Further steps of the research include to increase the level of precision of the impact analysis, waste distribution and waste purity to levels that support after demolition waste treatment decision-making.

世界各地で発生している森林や草原などでの火災、所謂バイオマス火災は、気候変動に伴い、年々大規模化する傾向にある。火災に伴い、温暖化ガスの二酸化酸素などが、放出されるため、火災と温暖化との相乗効果による急激な温暖化の進行が危惧されている。大規模なバイオマス火災は、人目に付かない辺地で発生する事が多く、リモートセンシングが有効である。飛行機観測は一部の地区に限られるため、大規模バイオマス火災が全世界的なスケールで認識され始めたのは、スペースシャトルが飛び始めた1980年代からである。宇宙飛行士により、森林や草原での火災状況が頻繁に撮影されるようになり、1985年にこれらの写真情報からの全世界火災地図が初めて作られた。その後、種々の観測衛星データを使う、バイオマス火災の検出方法が開発され、現在では、衛星データの自動解析による火災監視システムの稼動に至っている。観測衛星の赤外センサーにより、異常高温部いわゆるホットスポット (≒火災) が検出される。一般的には、衛星写真に赤い点でホットスポットを示し、煙の流れなどを見て、火災の大まかな状況を把握する程度にしか使われていないのが現状である。これは、ホットスポットデータの解析手法が確立していないためである。
そこで、本論文では、ホットスポットデータから、火災の焼損面積や火災の動向、特性の把握などを知るための―解析手法を、CADを利用して開発したので報告する。

自然界では量的な大きさに左右されない、ある図形の部分と全体が相似であるという自己相似性が多く存在している。また、造形的なリズムの中での意外性の混在はわれわれに心地よい環境をもたらし、デザインを豊かなものにする。フラクタルはこの両面の性質をもっている。われわれにとってフラクタル幾何学図形を組み込むことは、自然界に存在する形のシステムを内包する新しい建築・インテリア形体を造ろうとする試みであると考える。
フラクタル図形のもつ自己相似性のプログラムをCADに転用して空間構成を行った。大きさを持たないフラクタルに尺度を与えることで空間は幾何学図形の「美」を感じさせる、より自然形体に近いものとなった。フラクタルは居心地の良い空間を生成することのできる有効な手段であるとの確信を得た。

Recently, the invasion and establishment of naturalized plant species Buddleja davidii has verified and came to a head on the Mibu River water system in the Akaishi Mountains. The distribution and habitat conditions of B. davidii and native close-species Buddleja japonica were studied in order to grasp invasion and established factors, and to consider the influences of the former on the latter in the nine branches of the Mibu River water system. The eighty-two study plots were set up at intervals of five hundreds meters in their branches. As a result, the invasion and establishment of B. davidii were confirmed almost all branches. The appearance percentage of B. davidii was 45.1% in all study plots. The competition relationship between B. davidii and B. japonica, because of that a positive correlation of distribution was accepted in both species. The habitats of both species were established in the widely opened riverbed. The niches of the grain size and pH value of B. davidii had something in common with that of B. japonica. A positive correlation of distribution was accepted between B. davidii and the sabo dam.

Our regional cities are always scared to big fire accident or earthquake every day. But the number of capacity of shelter does not increase, because budget shortfall of local governments might not take them in action. In contrast, Wide-area evacuation simulation can easily figure out the image to antagonize the regional urban disaster. And more, it can calculate the possibility of blocking escape route when the city is broken, and make safe evacuation plans before disaster occurs.

Today, preservation of the traditional street landscape is one of the biggest concern to the urban planning and design. In this paper, the analysis of design elements is described which constitute the elevations of traditional Japanese town houses at NARA-MACHI. Then, the development of knowledge-based parametric design library is explained to assist urban design simulation for reproduction of the street landscape. The 12 components, e. g. a tiled roof and a lattice window, are prepared which can metamorphose their shapes according to the traditional architectural design rules. Using the library, the complex elevation of an existing traditional town house can consist of some objects, and also can be transformed for alternatives with the minimum change of parameters.

人が美しいと感じる図形にはある一定の法則があるとの確信から、幾何学図形を数式に基づいてコンピュータを用いて描画し、「美」の要素を分析・検討した。従来、手描きでは数学的な幾何学図形の均整美を充分に表現することはできなかった。三角関数のグラフがそうで、それが不等式となると、どのようなグラフになるのか見当もつかない。しかし、コンピュータは幾何学図形を正確に描写できるばかりではなく、思いつくままに書いた複雑な数式のグラフですら、即座に視覚化して美しい形態を提示する。グラフを回転させたり、途中まで計算させて、計算過程を残像で残してみるとまた、違った趣の形となる。2次元グラフを3次元に応用すれば、それは幾何学図形の織り成す空間となる。特に、自然の形態に見る対数螺旋に注目し、美を司るデザインの要素の考察を行った。

古い時代、人間が創造した建築物に文様を刻むとき、何らかのメッセージを込めたはずである。それは、建築物に住む側の人間にとって、子々孫々に至るまで生命が永遠に続き、さらにその繁栄を約束するような、そのような祈願を反映した呪術的なものを制作したであろうとの確信から、古建築における植物文様の意匠をCADにより対数螺旋を用いて合成し、再現した。古建築の植物文様において、対数螺旋は植物そのものを表現したり、または単純化されたパターンとなって繰り返したり、渦を巻いたり、植物文様の余白を埋めたりと、リズミカルに見え隠れし、永遠の生命を演出していた。それは見るものに華やかさを与え、植物文様を神聖視させ、永遠に見守られているという信念を抱かせるのに効果的なデザイン要素として、現代に至るまで引継がれ使用されているものであった。

Tsunami evacuation plans have been deliberately developed by local governments in coastal areas in Japan under guidance from the national government since before the Great East Japan Earthquake in March 2011. These plans, however, do not mention the time required for all local residents to evacuate to evacuation areas. This paper reports a procedure to design an effective tsunami safe town planning using multi-agent simulator (MAS) which identify a degree of evacuation risk in objective area. A case study is applied to one of the worst hit town of tsunami, in which additional facilities such as evacuation areas, safe buildings, and evacuation routes are proposed as well.
