This paper aims at clarifying the general properties of ultraviolet (UV) ray reflection of building materials. Firstly, we analyze UV ray reflection photo of building and landscapes in an university campus. It is observed that the intensity of UV ray reflection varies among materials. Secondly, we measured reflection intensity and ratio of UV ray for 42 specimens of building materials, and then classified those materials into 6 groups using multidimensional scaling method. The findings show that the UV ray reflection properties depend largely on the absorption ratio of U V ray and on the shape and roughness of material surfaces.

 The capital Kabul is growing at a fast pace than any other city in Afghanistan, it experienced a dramatic expansion over the past decade. The population has increased by almost 10% per year which caused a significant increase in the number of slums, as an unwanted consequence today informal settlements have covered about more than 69% of the city. This paper explains an afghan model of Land Readjustment which applied on an informal settlement area of Kabul with a very minimum compensation and contribution ratio. It appeared more applicable due to the preservation of historical buildings and low destruction cost.

&nbsp;This study aims to consider the value and possibility of a design method that integrates regional design and environmental design, through the five proposals in the competition for the new House of Parliament.<br>&nbsp;The major argument was how to integrate the modernism style and Thai regional design and, at the same time, the architectural ideology for responding to environmental and economic issues pervaded in Thailand.<br>&nbsp;The 5 proposals that made the final judgment stage of the design competition for the new House of Parliament suggest an aspect of a Thai architectural image that responds to demands from a society and an age. All 5 of the final proposals decide their form originating from regional design, but the judgment uses a system that also evaluates their environmental efficiencies. Thus, ways of suggesting national identity as well as improving environmental performance were expected, namely the way of integrating regional design and environmental design.<br>&nbsp;The environmental designs affecting the forms of the 5 proposals respond to the rating credits of LEED2009, which are related to heat island effects and energy efficiency. Especially, reducing heat load is an essential factor among the 5 proposals, not only to be recognized by LEED but also to clear the OTTV&middot;RTTV rating system that has operated in Thailand for many years.<br>&nbsp;And it is clarified that integrating methods are classified into two types according with types of environmental design, the &ldquo;Supplemental environmental design: incorporate supplementary environmental design into form based on regional design,&rdquo; and the &ldquo;Interactive environmental design: both regional design and environmental design affect deeply for the process of deciding the form.&rdquo; Furthermore, these integrating methods are classified into two types of expression, the &ldquo;Similized regional design&rdquo; and the &ldquo;Metaphorical regional design&rdquo;.<br>&nbsp;Through this design competition, it is suggested that architectural compositions that integrate regional design and environmental design are formulated in this age, in which both factors are demanded. These methods are also adaptable for other building types as possibilities for contemporary architecture observing through the tendency of architects in the age placing a high priority on environmental performance considering the effects of the environmental rating system on architectural compositions.

This paper analyzed how Jizo-Bon, small-scale religious festivals held widely in Kyoto, contributes for improving resilience of “cho”, the basic communities in the central urban area of Kyoto. We clarified that inhabitants who has no involvement or quite limited involvement to “cho-nai-kai”, community management associations are joining management of Jizo-Bon. The result means Jizo-Bon is an opportunity for inhabitants to be involved in “cho” except for “cho-nai-kai”. In addition, it means Jizo-Bon provide “cho” with “redundancy”, another key factor of resilient communities in addition to “diversity”. We also clarified that it is caused with characteristics of Jizo-Bon described as follows. 1. Distribution of management loads to various inhabitants Loads for management of Jizo-Bon are distributed to the extent that each inhabitant can bear them. For example, people can join in the management only with "arranging place", "supporting events on the day" which is easier to bear than other roles as "manager of Jizoubon", "preparing for events" etc. It is also clarified that inhabitants who are usually difficult to be involved in communities as those who are not belong to "cho-nai-kai", those who moved in "cho" recently, single old inhabitants and apartment inhabitants participate in Jizo-Bon. It means Jizo-Bon contribute to "Diversity" of "cho". It is expected that the people involved in Jizo-Bon management to make roles also in "cho-nai-kai" in the future. However, the people differentiate the former involvement from the later as far as we analyzed in this paper. That make it possible the people who cannot bear much loads of "cho-nai-kai" management to be involved in "cho". 2. Flexible meaning corresponded with community situation Meaning of Jizo-Bon is flexible corresponding with situation of communities and people can join in it with their own purpose or motivation. The recognition about Jizo-Bon is different in the two "cho" communities selected as survey area in this paper. Inhabitants in "A cho", a community managed mainly by people who are living there for long term, recognize Jizo-Bon as "religious events" and "traditional events". On the other hand, inhabitants in "B cho", a community including people who moved in "cho" recently, don't recognize as "A cho" and accept it as rather for "communication among inhabitants" and "fan of inhabitants". It means that Jizo-Bon is sustaining by adding or changing meaning of itself corresponding with characters of community as its population structure. In addition, we also clarified that Jizo-Bon is an opportunity for people who moved inside the city to become familiar with their new community because Jizo-Bon is held widely in the urban area of Kyoto. The image of Jizo-Bon shared among citizens seems to be a key factor making it possible for various inhabitant to join and collaboratory manage it. Jizo-Bon is a resource which provide various inhabitants with opportunity to involve in communities depending on their situation and interest. It is precious especially in the context in which decrease of interest and lack of manpower for community management is serious problem. On the other hand, once Jizo-Bon is lost, it is difficult to restore because the characteristics of Jizo-Bon we clarified in this paper is acquired through long-term experience. It is necessary to advocate and measure for conserving Jizo-Bon for the future.

The interior of the dome on the original form of Tokyo Station, which was finished with various decorations, was one of the most distinctive features in its design. Despite the fact, there exist a number of unknown facts on the dome design. For example, it has not been clarified yet how the relation between the design, technique, architect, or Kingo Tatsuno, craftsmen, and so on, worked together on the formation of the dome. This paper is to clarify the design of original Tokyo Station and the position of the building among the works by Tatsuno and other architects in those days.

The present paper aims to clarify the characteristics of Chengilli Kilisesi, through comparative analysis on internal frame composition among its adjacent architectural culture in the same period. As a result, it is recognized that the unique composition of its drum with eight exedrae is similar to centralized domed Armenian churches, especially to the main body of the octafoil church at Varzahan, while conspicuous similarity is found between Chengilli Kilisesi and the churches in Tao-Klarjeti, in regard to usage of squinch-installed pendentives. This phenomenon implies that the characteristics of the plural architectural culture might be involved in this monument.

Two experiments were conducted to determine whether color, lighting and material interact among each other in affecting the evaluation of an interior's ambience. Experiment 1, in which interior models with varying wall color and lighting were evaluated by subjects, showed that the effects on ambience evaluation of wall color and lighting are essentially independent of each other. Experiment 2, in which wall color, lighting and wall material were changed, demonstrated that wall color and material interact with respect to the parameters "beautiful" and "serene." The parameter "warm," however, showed no interaction among the three factors, and its evaluation was explainable as the linear sum of the effects of wall color, lighting and wall material.

The system which uses the natural energy, are deeply related with the weather factor. Because the atmospheric radiation quantity and the nocturnal radiation quantity influence mainly, the Sol-Air Heat Pump System which radiates in to the sky with the radiation cooling in night must examine these values sufficiently. Then, it did long-range observation with the observation receptacles such as the wet and dry-bulb thermometer, the pyrheliometer, the infrared radiometer and the SAT meter. It made an atmospheric radiation quantity estimated formula from those observation results and the practicality of the formula was shown.

This paper presents results of measurements and analysis on grid-connected PV generation systems installed on 132 residential houses in Tokyo and Kanagawa area. The annual PV efficiency along with its parameters as well as the effect on CO2 emission reduction and on power demand peak cut are shown based on the data obtained from October 1998 to September 1999. Result, of the analysis is that configuration of installed panel, module temperature and inverter efficiency have dominant effect on PV system efficiency. Single-panel configuration has higher efficiency than double panel configuration where two panels are installed on each inclined plane of the roof. The latter configuration suffers from decrease in efficiency by 20% in the winter season. The efficiency of single panel configuration decreases by 0.28% as the backside temperature elevates one degree. It was observed that the smaller the DC input under a certain threshold, the lower the efficiency was. The PV system installed demonstrates the contribution to 250kg-C/year of CO2 emission reduction and 1.15kWh/h of power load peak cut per house on average.

The objective of this paper is to get clues to improve the environmental conditions of Yamanobe area in Kyoto based on the consideration of their spatial quality. Yamanobe area in Kyoto means the mountainside area of three mountains (Higashiyama, Kitayama, and Nishiyama) which surround Kyoto City. Yamanobe area is historically characterized from the facts that it was funeral area from the ancient times, a lot of discriminated people dwelled there until the recent times from the Middle Ages, there were many shrines and temples, a lot of places to enjoy nature was located there in the Edo era, and so on. Although Yamanobe area was very different from the inner urban area in terms of spatial, social and cultural quality, those two areas have long interrelated each other. However, Yamanobe area is much changed especially in high economic growth period after the second world war. The authors make the changing process clearly based on field studies and analysis of historical maps. Also, we want to extract the spatial quality of Yamanobe area through the analysis. In this paper, we take up Toribeno area (mountainside of the Mt. Amidagamine in Higashiyama area) in Kyoto, that is one of the most typical Yamanobe area in Kyoto.

The 1995 Hyogo-ken Nanbu earthquake struck Kobe and adjacent cities, one of the most densely populated area in western Japan, and killed more than 6,400 people and destroyed more than 150,000 buildings and houses and tens of highway and railroad bridges. It is very important to examine the ground motion characteristics in the severely damaged area during the mainshock for understanding how buildings and bridges performed and why they reached collapse. Unfortunately very few strong ground motions were recorded in the severely damaged areas during the mainshock. In this study, we attempt to estimate ground motion at severely damaged sites by using the empirical Green's function method (EGF method). We derive a best source model with three asperities after several try and error with forward modeling by the EGF method. We estimate strong ground motions at sites, where the mainshock was not recorded, using aftershock records. The synthesized motions in the near-fault region in Kobe were characterized by two large long-period (1 to 3 seconds) pulses due to the forward rupture directivity. Peak horizontal acceleration and velocity of the synthesized motions at the heavily damaged sites are about 1,000 cm/sec^2 and 130 cm/sec, respectively, while those at a rock site in near-fault region show about 300 cm/sec^2 and 60 cm/sec. The reason why so strong motions hit the heavily damaged sites is that the large long-period pulses which come from two asperities in the Kobe-side segment of the fault were further amplified by the basin edge effects.

&nbsp;The aim of this paper is to verify the effectiveness of people walking with their dogs to keep an eye on their neighborhood, or &ldquo;the eyes in the community&rdquo;.<br>&nbsp;It is considered that demonstrating the characteristics of the spatial cognition of walkers with dogs is a useful way to support such an effect. Therefore, in this study, we compare sketch maps drawn by two groups of residents, first dog-owners who are used to walk dogs in their neighborhood, and second non-owners who do not own dogs, and analyze how dog-walkers perceive their local area in order to clarify the roles they play in the community.<br>&nbsp;The survey area is Gokanme-cho, Seya-ku, Yokohama-shi and its surrounding area. We have distributed survey forms to 40 people living in the area, and obtained 25 effective answers. In the survey, we asked each subject to draw a free drawing map of his/her neighborhood and mark an area where he/she greet daily to neighbors. In addition, we asked dog-owners to mark his/her daily walking courses with dog and also places where he/she have make contact with others on the sketch map.<br>&nbsp;Although there is no significant difference between total lengths of paths drawn by the two groups, an range of paths drawn by dog-owners extends beyond major roads recognized as edges of the area. This result may be explained by the fact that dog-owners seek suitable courses for walking-dogs widely and they often have several walking courses.<br>&nbsp;Dog-owners are potentially &ldquo;the eyes in the community&rdquo; to watch children in the park, because they walk with dogs more widely than non-owners and visit such places with few passers-by, for example, small parks locate by an expressway side-roads and places out of reach of people's eyes. On the other hand, they may choose such places for avoiding people's eyes because they let their dogs to shit. Therefore, there can be a duality with the dog-walkers' &ldquo;the eyes in the community&rdquo;.<br>&nbsp;In parks where access with dogs are restricted, recognition rate by the dog-owners is low, and in contrast, parks open to dog-walkers show high recognition rate. The perception rate by dog-walkers seems to be linked to the experience while walking their dogs.<br>&nbsp;Characteristic places where dog-walkers often interact with others are spaces where they can stay safely with dogs, and spaces open to dog-walkers stay. It can be said that even small spaces will attract human interactions while walking dogs.<br>&nbsp;Thus, this paper has shown that the walking with dogs can be "the eyes in the community" and effective for causing new interaction. It occurs beyond the range of daily greetings.

Since 2005, advances in next-generation sequencing (NGS) technologies have revolutionized biological science. One particular application of NGS technologies is to elucidate microbiomes in built environments. We are currently conducting a series of studies on the elucidation and control of mass infection mechanisms based on dynamic measurement of environment microbiomes. The objective of this study is to clarify the dispersion characteristics of oral bacteria in built environment. Bacterial communities from occupants’ hands and oral cavities, doorknobs, desk and keyboard surfaces, and air in a university laboratory were investigated. For each sample, the variable region 4 (V4) of the bacterial 16S ribosomal RNA (rRNA) gene was amplified by polymerase chain reaction (PCR) using the primer set 5’-acactctttccctacacgacgctcttccgatct-GTGCCAGCMGCCGCGGTAA-3’ (1st_515F) and 5’-gtgactggagttcagacgtgtgctcttccgatct-GGACTACHVGGGTWTCTAAT-3’ (1st_806R). The 16S rRNA amplification protocol version 4_13 was used as a pretreatment with the Next-Generation Sequencer (NGS, Illumina MiSeq system v2). DNA quality was checked using the Agilent 2200 TapeStation. All samples that contained the necessary quality and quantity of nucleic acid concentration for analysis were then analyzed. The produced sequence library was mixed. To improve the quality of the mixed sequence library, a refining processing using the AMPureXP PCR purification system (Beckman Coulter, Inc.) was carried out. About data analysis, the leads for all samples obtained in the sequence analysis (lead 1 and lead 2) were unified, and then assemblies of lead 1 and lead 2 were extracted, followed by clustering and representation arrangement. CD-HIT-OTU was used for alignment extraction and representation arrangement. Basic Local Alignment Search Tool (BLAST) search was performed using the DDBJ 16S rRNA database (version 2016 01 12) by querying representation arrangements. For sequencing, alignment (PyNAST) and genealogical tree creation (FastTree) were performed using a phylogenetic system (RDP classifier), and template alignment was accomplished using the QIIME pipeline. Rarefaction analysis and comparison with a bacillus solution were performed using the QIIME pipeline. The main results obtained by this study are shown as follows. 1) Higher rank 6 phyla of 98% of rates of all 18 phyla being detected and occupying to the whole on a bacterial phyla level more than at composition ratio 1% were Firmicutes (44.9%), Proteobacteria (30.2%), Actinobacteria (9.5%), Bacteroidetes (8.4%), Fusobacteria (3.3%) and Cyanobacteria (1.7%). 2) Higher rank 15 genera of 70% of rates of all 149 genera were Streptococcus (28.4%), Haemophilus (9.0%). Prevotella (5.0%), Staphylococcus (4.5%), Neisseria (4.2%), Corynebacterium (3.8%), Pseudomonas (2.8%), Rothia (2.8%), Fusobacterium (2.1%), Enhydrobacter (1.6%), Veillonella (1.4%), Leptotrichia (1.2%), Granulicatella (1.2%), Acinetobacte (1.1%), Porphyromonas (1.0%). 3) On the species level, reads of one or more larger than 3 orders had 33 species from each sampling point, and about 30% of bacteria were pathogenic bacterium or opportunistic infection bacterium. In particular, P. melaninogenica which is a disease germ in a mouth, and R. dentocariosa and R. mucilaginosa which is an opportunistic infection bacillus in a mouth were detected from all parts. 4) By the analysis of species intersection of each group of bacteria, reads larger than 3 orders from all samples were P. melaninogenica and R. aeria and both bacteria are causative organism of respiratory tract infection. That is, the fact that oral cavity bacteria of this human associated were detected from all surfaces and indoor air showed clearly that oral cavity bacteria had dispersed in all parts among indoor environment.

The purpose of this study is to consider the characteristics of urban space in Kyoto based on the analysis of the distributions of Cemetery. From the ancient times, there was funeral area in the hillsides of three mountains (Higashiyama, Kitayama and Nishiyama), which surround Kyoto City. The urban periphery was very different from the inner urban area in the term of spatial and cultural quality and those two areas have long been interrelated each other. Cemeteries located in the urban periphery had been greatly changed on the process of so called modernization from Meiji Restoration. This paper clarifies the changing of distribution of cemeteries based on the analysis of historical maps. Major point of consideration is the transformation of urban space in Kyoto through the analysis. This paper concludes that the environmental change cemeteries and around cemeteries brought the fall of the relative relation between a life space and urban periphery.

&nbsp;Traditional houses in Western Afghanistan have domical vault roofs. Such houses are not limited to the Old City but are instead distributed throughout the municipal area of Herat. For this study, we used satellite images from 2017 to locate 11,754 houses with domical vault roofs within the municipal area of Herat and then calculated their density. Field surveys were conducted to investigate the sites with a higher density of such houses. The study identified seven high-density sites and classified them into three groups; 1) monumental, 2) pre-1960s old residential villages along canals and 3) post-1960s residential settlements at the urban fringe.

In this study, I reserch Otai which is a post town of old Nakasendou in the Edo era. I analize the regional characteristics of the house plan and the townscape in the "Shukuezu"; old maps in the middle of the Edo era. As a result, the following things can be said ; relatively small houses were intensively seen both in Kamimachi and Shimomachi while rather big houses were seen in Nakamachi, each town had its own streets view, those small houses had many similarities with neighbor farmhouses in terms of the size and the house plan.

This paper reveals the reason and the meaning of change in design for Tokyo City Research Hall, Tokyo Public Hall. Four main changes were made at the time of construction of the building : 1) change in location of the building site ; 2) change in the shape of the hall ; 3) change of structure and 4) modification of the overall design of the building. The most important factor influencing the modification of the overall design was Satoh's desire for the new building to provide a visual contrast to the Japan Kangyo Bank. He often discussed the need for "urban beauty." Satoh seized the opportunity in the aftermath of the Great Kanto Earthquake disaster to achieve "urban beauty" with the construction of this building.
