According to a survey by the Ministry of Health, Labor and Welfare, the number of mood disorders tends to increase year by year in Japan. Under such a background, from December 2015, it is obliged for employers to perform stress checks of workers once a year. In such a stress society, improvement of office environment is an urgent issue. As is well known, some foliage plants have effects of humidity control and VOC removal from indoor air, improvement of productivity and reducing workers' mental stress as well. In the past, a number of previous studies on indoor plants focusing on these effects have been seen, and most of them were implemented in simulated office spaces in the past. However, recently Iwasaki et al. and Matsumoto et al. have installed some plants in actual office spaces and the psychological effects of plants on office workers are beginning to be considered. The objective of this study is to examine the effect of indoor plants on physiological/psychological responses and productivity, and to demonstrate the mental healthcare for office workers. In order to clarify the effect of indoor plants, we conducted a demonstration experiment in an office. This experiment aims to clarify the effects of indoor plants arranged in workplaces on workers' mental health, such as physiological responses, psychological responses and productivity. The experiment was performed in two rooms (Office A, Office B) in an office on the eighth floor of a building located in Kyoto, Japan. Office A was a call center and Office B was a general office. Subjects were office workers working in one of the above two rooms. Twenty-two healthy people in Office A and 19 healthy people in Office B participated in the experiment. Participants were required to measure physiological responses and answer a Web questionnaire after work once or twice a week. Each office worker worked as usual during the experiment period. The experiment was performed from the end of March 2016 to the beginning of September 2016. In the experiment, nine cycles (one cycle is two weeks) were conducted while changing the type of plants. Plants were arranged in the same amount as possible with a green cover ratio of 10 %. A preliminary experiment without plants was conducted as a reference case. Survey items are divided into four items: indoor environment (temperature, humidity, CO2 concentration, illuminance, sound level), physiological responses (salivary amylase activity, critical flicker fusion frequency (CFF)), psychological responses (a questionnaire survey through the Web based on SAP and a questionnaire survey “Jikaku-sho shirabe” by which evaluated work-related fatigue feelings and fatigue symptom intensity), and productivity (simple task, calls per hour (CPH)). Indoor environment indices of this study ranged wider than those of the laboratory experiment. The result of evaluating the thermal comfort of each office using PMV showed that Office A was slightly warm, while Office B was neutral. The relaxation effects of plants on visual fatigue were found to be significant in CFF for female when arranging the plants with some petals. Mean score of fatigue symptom intensity showed that foliage plants have a significant effect to reduce the feelings of drowsiness. Effect of the improvement of the productivity using plants installation could not be confirmed in terms of simple task and CPH. Our results suggested that plants installation in office space has some mental healthcare effects, although this study had some limitations because of the demonstration experiment. Some experimental problems related with plants preparation restriction, plants order, a variation of some indoor environment indices, LED lamp lightings are to be solved in the future.

This study aims at accounting for validity of the theory of space by O.F.Bollnow for dwelling environmental education, and trial study on making clear of the characteristic of "Raum, den man hat" Bollnow said by considerations about the representation of Primary Scenes. According to the theory of space by Bollnow, it is principal understanding of space on the true meaning to dwell that man get "Geborgenheit" in "Raum, den man hat". As a result, Primary Scenes are valid for realizing "Raum, den man hat" through having unity with man, and "Geborgenheit".

The city is so complicated that we can hardly describe its totality. The purpose of this study is to clarify how we perceive cities, and what we recognize there. We introduce the concept of modality in order to grasp the total phenomena between human and environment as the global meaning of cities. We conduct walkthrough experiments in Kyoto City, and ask subjects of those experiments to write down what they feel as it is. The results are as follows.1) A theoretical model of urban modalities is constructed based on possible world semantics.2) Urban modalities can be described and visualized based on the data of walkthrough experiments.

Edward Relph, a Canadian geographer said that there are psychological connections named “sense of place” between people and place, and they are important in terms of making good places. In Japan, It is said that the urban developments without consideration of psychological connections have destroyed places and their social memory. The purpose of this research is to analyze the character and inheritance of “sense of place”, by observing habitual use of places inherited in university students in Takadanobaba. There were three investigations and followings were obtained: 1) The whole picture of places where university students usually use It became clear that the places where university students usually use can be divided into fifty four groups based on the industry classification. University facilities, Izakaya, Ramen shop etc. were the most popular places. And it became clear that the places where university students usually use can be roughly divided into nine groups through analysis of purpose for using place. There are the places for intellectual activities, cultural activities, sports, shopping, drinking parties, eating, gathering, killing time and rest. Moreover, it became clear that university students were relating nine places with each other to be network. 2) The target youth’s formation process of Local-oriented mind 162 habitual uses of places are gained through the survey. They can be roughly classified into two actions. One is action done by using necessary items already prepared in the places, and the other is actions done by bringing necessary items from other places by themselves. The latter is done in the outdoor space, and it became clear that it is done outside of university more than inside of university. It is confirmed that most places where habitual use of places are done were located around each campus and Takadanobaba Station. And it became clear that many habitual uses of places are done in three types of places; places for leisure activity, places as node, and places for moving. 3) Actors for inheritance of “sense of place” 134 habitual uses of places are inherited beyond school grade. Groups or people keeping on planning events and the groups with multi-generation members are main actors for inheritance of the habitual use of places, thus they are considered to be one of the actors for inheritance of “sense of place”. And it became clear that two environments were important for the inheritance of “sense of place”; appropriate urban space for purpose and the experience of seeing behavior of others.

This paper focuses on how to reduce CO2 emissions regarding construction materials. We compared section by section the amount of CO2 emissions from the four different houses. Next, we made an improved plan that took away the first floor that was constructed with reinforced concrete, as well as the interior decorations which emitted less CO2 during their factory production. The following results were obtained.1) We determined which sections of the four houses had less construction waste. We determined which sections of the four houses emitted less CO2 during their production.2) The total amount of CO2 emissions per floor from construction materials is 318.8kg-CO2/m2~498.1kg-CO2/m2.3) The proposed countermeasure that took away the first floor reduced CO2 emissions by 15.7×103kg-CO2, a decrease of 30.4%.The proposed countermeasure that used the interior decorations, which emitted less CO2 during their factory production, reduced CO2 emissions by 5.1×103kg-CO2, a decrease of 9.9%.The countermeasure that the authors described in their improved plan reduced CO2 emissions by 20.8×103kg-CO2, a decrease of 40.3%.

The objective of this paper is to understand the interrelationship between the location of convenience stores and socioeconomic data in the vicinity, using the geographical information system(GIS). The discriminant analysis is applied to actual data collected in the City of Tsukuba to explain the existence of convenience stores in each of its 185 districts. We found that the number of households, the volume of traffic, and the number of large scale shopping facilities (such as supermarket or department store) in the district are positively related to the existence of convenience stores, while the number of persons per household is negatively related. This last variable is believed to show a rural characteristic of the neighborhood. The overall ratio of correct prediction by the model is 78 percent. The use of the GIS is effective in graphically displaying the result of analysis as well as in manipulating socioeconomic data as inputs into analysis.

1. This thesis mentions about 142 stained glass works which are thought to be made by Shintaro Kiuchi, based on files and data which the Kiuchi family has kept.2. The designs of those works are classified into two --- abstract and concrete. Then they are categorized more into details.3. While the design of stained glasses in Japan didn't change much from the Meiji era to the end of Taisho era, ship designs were comparatively found a lot. This is because of the prosperity of shipping business, which reflected the new era's arrival. Also, it was because Shintaro Kiuchi was fond of ships.

Authors have been conducting the field research under the title ‘Origin, Transformation, Alteration and Conservation of Urban Space of Colonial cities’ since 1999. This paper discusses the characteristics of the Spanish Colonial cities created in the Cuba Island. In the period of the Spanish urbanism in America, approximately a sixty of colonial cities were established in Cuba. As cartographic database, 916 images and maps from AGI (The Archive of the Indies in Seville-Archivo de Indias de Sevilla), are used for analysis.This paper deals with hatos and corrals system, which is very unique land distribution system in Cuba. In the analysis of maps of hatos and corrals, we classify them into several types and analyze the case of La Habana.

The philosopher Ludwig Wittgenstein designed Stonborough Villa with the collaboration of Paul Engelmann. Stonborough Villa is a “Mathematically configured” building very rare in modern architecture. The aspects that distinguish the Villa can be observed in many calculated details such as the boundaries of the walls, which vary in thickness from room to room creating a wall projection, the height of the ceiling and the Double Doors. This research is focused on the doors on the main floor. The placement and the role the doors play in connecting the rooms is an important factor in this particular architecture. The dimensions and positions of the doors are determined by the internal logic of the Hall with strict precision. The main floor is centered around the Hall where the doors connect to every room in the house in a counterclockwise arrangement: The Breakfast room (Frühstückszimmer), Living room (Wohnzimmer), Salon (Saal) and Dining room (Speisezimmer), each having a maximum amount of openings with a respective sequence of 1-2-3-4. The spacing and symmetry when viewed from the room as a whole or as the wall surface the location of the doors in each room and the arrangement, they have their own independent logic. The doors on all five rooms, including the Hall, are Double Doors; some consist of Single Double Doors and Pairs of Double Doors. This paper looks to classify the types of door arrangements in the five rooms of the Stonborough Villa's main floor. Based on the patterns that emerged a Door Schedule was produced. In order to produce the Door Schedule for this research it was necessary to make a comparative study because of the lack of information regarding the subject. This also included and on-field investigation in October of 2013 using a laser distance measuring instrument with which new data was compilated. Through the comparison of the doors that at first sight look as if they had the same shape and dimensions, it was found that there are minute differences in the dimensions. This is most notable in the room connections where there are Pairs of Double Doors, in which, the front door and rear door have different sizes. The arrangement and logical systems mentioned previously can be applied in the Dining room as follows: The four doors are arranged symmetrically while at the same time consist of two types of opening and closing mechanisms. From the Dining room on the far left the Pair of Double Doors lead to the Hall, one opening into the Dining room while the other into the Hall. The remaining three doors open into the Dining room. After surveying the current dimensions of the doors, the Pair of Double Doors which lies between the Hall and the Dining room we can establish that the Double Door which opens into the Hall and the Double Door opening into the Dining room in spite of having the same shape the size is in fact different. These differences also exist in the Pair of Double Doors connecting the Living room and the Salon. For these reasons, we can say that in Stonborough Villa the proportions of the Pairs of Double Doors are adjusted to suit the internal dimensions of the rooms into which they open. The Pairs of Double Doors in Stonborough Villa have a relatively wide spacing in between, this generates a different dynamic whether the doors are opened or closed. With the completed analysis of Stonborough Villa's doors it is clear to see the crucial purpose they possess in the spatial configuration of the House.

In this paper, we aim to make a reference for planning of the lobby and foyer in multi-purpose hall, theatre and concert hall. To study our theme, we investigate the use of the lobby and foyer during not running time. We send questionnaires to house keepers in 477 halls. In this questionnaire, we ask them how to use their lobby and foyer during not running time. In the result, the lobby and foyer is used for programs which are planned by their own, and rented for various purpose. They answered various problems on such a use and the idea in the future.

The purpose of this paper is to quantitatively determine the removal performance on cedar pollen of domestic air cleaners which have widely been utilized in ordinary houses. Five domestic air cleaners were tested in an experimental chamber, using cedar pollen and the JIS Test Powder. The evaluation were made with an index of equivalent clean air rates (ECAR). The results showed that the removal rates of cedar pollen were 19.12〜180.2(m^3/h) for 0.3μm particles, and 18.7〜213.0 (m^3/h) for 0.5μm particles except for one type and with JIS Test Powder 20〜50(m^3/h) for all type of domestic air cleaners. The pollen has smaller particle portion than the JIS Test Powder No.11 and the performance of cleaners cannot be estimated simply from the morphological size distribution of the test aerosols. The analytical prediction of pollen concentration were made and compared with the results of experiment to show a fairly good fit for particles smaller than 1μm.

The aim of this study is to propose pollen prevention measures in buildings by examining the mechanisms of indoor concentration decay theoretically with pollen grains as the main target, and estimate indoor concentration using theoretical formulas. We first analyzed the mechanism of the indoor pollen concentration, and verified predictive formulas based on actual measured values. Next, assuming the outdoor pollen concentration, the indoor concentration was estimated. It was shown that by making assumptions for the outdoor concentration and conditions, the indoor concentration could be estimated using a theoretical formula.

Homeless people have built shacks and settled down in Shibuya-ku / Miyashita Park. In this paper I tried to investigate the need for community, especially through the participatory research by the homeless people themselves in this park. It shows that the homeless people living in the park have formed neighborhood relation and this relation contributes to sufficiency of their basic human needs, house construction through mutual support, cooperative approach for the life rebuilding. Further, it shows that they have practiced many kinds of housing activities through the homeless peoples' autonomous council, which they established, and that they also express much interest in joint resettlement. Important needs for the homeless are not only shelters, but also improvement in their living environment based on autonomous community while living together. Therefore, as a policy, preparation of systems for enabling them to practice such kind of their autonomous activities is more necessary than institutionalization.

The following discoveries were made about the factors affecting the usage period of main halls. 1. The factors contributed to the previous main hall being used for a short period were natural disaster at Edo Period. 2. Priests wish to continue using current main halls for the period of similar tendency as the ideal period of use. 3. The future planned periods of use of main halls seem to be affected by structural issues such as aging of materials. 4. There is a trend of the future estimated period of use being longer when previous main halls were used long. 5. Newly established temples with main halls of non-wooden construction are used for a short period.

From the study of the Japanese buildings and the exhibits at the Louisiana Purchase Exposition in 1904, St. Louis, it came to clear that Japanese buildings were built in the three areas, Japanese government place, each Japanese section of the exhibition buildings by the U.S.A., and in the 'PIKE' that was an entertainment place. All Japanese buildings were traditional Japanese style, and made by Japanese carpenters like the exhibition at Philadelphia 28 years ago. But we can recognize some element of transformation in the technique and the materials in that buildings. It is one of the transitional time at the fair of St. Louis through the international exhibitions in 19-20th century.

We estimated the fault of the 1924 Tanzawa earthquake (Mj7.3), which was the largest aftershock of the 1923 Kanto earthquake (Ms8.2). We could successfully reproduce the observed waveforms in central of Tokyo based on the estimated fault model. This is very important to investigate the characteristics of ground motions by M7 events occurring in the Tokyo Metropolitan area because we only have a few observed waveforms of such events in central Tokyo. Finally, we calculated ground motions around Tokyo metropolitan area by the estimated fault model. The simulated ground motions do not exceed the design spectra around the area but in west of Kanagawa Pref.
