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.

This paper analyzes the structural planning concepts reflected in the roof trusses of Kazuo Shinohara’s First Style wooden houses, focusing on four houses (House in Komae, Umbrella House, House in White, and House of Earth) examined during recent restoration projects. In each house, the roof load was intended to be converted into axial forces and transmitted to the supporting structures. The roof truss members were intentionally composed of slender timber, with forces being transferred via metal joint fittings. Shinohara’s structural planning concepts were realized with the support of the structural engineer Ichiei Tsuge.

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。

The purpose of this paper is to quantitatively analyze and evaluate the pond’s water storage capacity, quantity of stormwater runoff, rainwater stock, and infiltration capacity. This will help to clarify the function of green infrastructure in Japanese gardens. We selected Sankeien garden in Yokohama as the study site for this research. Sankeien is divided into seven areas: 1. Woodland, 2. Grassland/shrubland (including lawn), 3. Bare ground, 4. Pond, 5. Gravel ground, 6. Paved area, 7. Building ground. The total water volume of the five ponds in the garden is 11,389 (m3). This value corresponds to a rainfall of approximately 60 (mm) per hour. This paper clarified the basic area of Sankeien. The current rainfall-runoff volume is 32,540 (m3/sec). Assuming that the entire Sankeien is paved, the stormwater runoff is 64,680 (m3/sec). The rainwater stock capacity was analyzed by horizontal projected area and surface area. The rain stock capacity by horizontal projected area and surface area were 73.28 (mm) and 74.02 (mm), respectively, which are almost the same value. The present Sankeien can withstand a torrential rainfall of approximately 74 (mm). The infliltration amount exhibits a difference of 171.97 (m3/hr) between the measured value and the theritical value.

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.

This study investigates the geometric operations of “axis lines” and “Tsuzumi-shaped” compositions in Kenzo Tange’s Memorial Hall for Students Who Perished in the War, clarifying their design logic and role in generating monumentality. Although the work remained obscure due to the lack of publication at completion, the plan contains axis-like lines and successive trapezoids that suggest continuity with Tange’s early morphological strategies. Existing studies focus on landscape aspects—topography, views, and the symbolic tower—while disregarding the architectural significance of axes or Tsuzumi-shaped forms. This study therefore analyzes eleven pre–Expo ’70 works referencing axes and seven works employing trapezoids or Tsuzumi forms, extracting their characteristics and applying them to the memorial. The analysis shows that Tange’s axial principles, derived from Le Corbusier’s Palace of the Soviets, emphasize axes toward symbolic voids, orthogonal intersections forming plazas, and spatial structures guiding movement. The trapezoid and Tsuzumi analysis reveal that pairing trapezoids along their short edges was a recurring technique for reinforcing monumentality and spatial direction. Applying these criteria to the memorial identifies eight trapezoids of varying geometries and six Tsuzumi-shaped pairs, one of which closely parallels four key works—CHAHTEAU D’ART, the Greater East Asia Construction Memorial Plan, the Peace Cathedral Proposal, and the Hiroshima Peace Memorial Park Competition. The overlap between a drawn plan line and an analytically derived axis further suggests intentional axial design. In conclusion, the memorial embodies Tange’s concept of monumentality through the integrated use of axis lines and Tsuzumi-shaped forms. His technique of creating spatial tension by juxtaposing identical geometries is evident here, contributing to the solemnity appropriate for a commemorative environment.

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.
