Objectives: In spite of the importance of green space for reducing obesity-related problems, there has been little exploration of whether access to green space (e.g., parks and recreational facilities) influences the obesity rate of adults in the United States. The purpose of the study was to investigate the relationships among accessibility of green space, obesity rates, and socioeconomic and demographic variables among adults living in the State of Indiana, United States. Methods: We conducted a secondary data analysis to investigate the relationships among accessibility to green space, obesity rates, and socio-demographic variables with employing Geographic Information System in order to measure the accessibility of green space. Results: This study found that accessibility of green space served as a strong predictor of reduced obesity rates among adults (β=-2.478; p<0.10). In addition, adults with higher education levels, as well as better access to green space, were found to have even lower obesity rates (β=-0.188; p<0.05). Other control variables such as unemployment rates, food security, and physical inactivity are additional factors that influence obesity rates among adults. Conclusions: Accessibility of green space may play an important role in facilitating physical activity participation and reducing obesity rates.

The purpose of this study is to gain an in-depth understand of the dwelling needs of residents who are interested in Cohousing. To do this, we interviewed 18 urban residents who wanted a community life; investigated consciousness of neighbor relationships; and analyzed their consciousness of Cohousing residences, preference types, and spatial needs. At first the research has revealed that the neighbor relationships of the participants were not very close and that there was a difference in awareness levels between a 'good neighbor' and 'strange neighbor' with regard to neighbors, though all of the participants required a vitalization of these relationships. Second, Cohousing residence types could be divided into the 'life preferred type' and 'space preferred type', depending on the differences of pursued dwelling interests. These could be further segmented into the 'leisure life preferred type' and 'daily life preferred type', 'public space preferred type' and 'individual space preferred type'. Thirdly, preferences for Cohousing types varied depending on differences in priority with regard to important concepts of the social-physical environment (e.g., community property, effectiveness, naturalness, economic feasibility, and individuality). Finally, we found that the greatest needs were for public gardens and exercise space as aspects of the common spaces. Agreements pertaining to special use were considered as most important during the design process of the common spaces.

We will define a smooth fuzzy closure space and a subspace of it. We will investigate relationships between smooth fuzzy closure spaces and smooth fuzzy topological spaces. In particular, we will show that a subspace of a smooth fuzzy topological space can be obtained by the subspace of the smooth fuzzy closure space induced by it.

We develop forecast models of daily probabilities of major flares (M- and X-class) based on empirical relationships between photospheric magnetic parameters and daily flaring rates from May 2010 to April 2018. In this study, we consider ten magnetic parameters characterizing size, distribution, and non-potentiality of vector magnetic fields from Solar Dynamics Observatory (SDO)/Helioseismic and Magnetic Imager (HMI) and Geostationary Operational Environmental Satellites (GOES) X-ray flare data. The magnetic parameters are classified into three types: the total unsigned parameters, the total signed parameters, and the mean parameters. We divide the data into two sets chronologically: 70% for training and 30% for testing. The empirical relationships between the parameters and flaring rates are used to predict flare occurrence probabilities for a given magnetic parameter value. Major results of this study are as follows. First, major flare occurrence rates are well correlated with ten parameters having correlation coefficients above 0.85. Second, logarithmic values of flaring rates are well approximated by linear equations. Third, using total unsigned and signed parameters achieved better performance for predicting flares than the mean parameters in terms of verification measures of probabilistic and converted binary forecasts. We conclude that the total quantity of non-potentiality of magnetic fields is crucial for flare forecasting among the magnetic parameters considered in this study. When this model is applied for operational use, it can be used using the data of 21:00 TAI with a slight underestimation of 2-6.3%.

This comparative study between Korean and German housings aims at understanding different structural systems in the indoor and outdoor spaces, depending upon the user′s perception of the socio-cultural attributes. The analysis starts with four alternative contrary assumptions, that appear in morphological forms of dwelling; 1) linear distribution vs. areal distribution of residential districts, 2) mirror system vs. comb system in the layout of plot plans 3) organization of front vs. back outdoor spaces and 4) opening vs. closing in the indoor spaces. A clear difference is found between Korean and German samples in view of public and private relationships between indoor and outdoor spaces as well as the intermediate space. In the korean housing there always exists a symbolic and psychological territory of a certain sphere. On the other hand, outdoor space passes through various phases only to form a certain hierarchy even in a private space and, thereby, sets a boundary between private and public areas. In the case of Germany, the building itself draws a clear line between private and public outdoor spaces, and therefore the outdoor space has a "front" and "back". Thus, Germany′s private space may face a genuine public space and street, which is rare in the Korean housing. Although the layout of indoor space in the korean housing tends to be open, such an openness may be outstanding in living and dining spaces, kitchen and various accesses to rooms. In the case of Germany, such indoor spaces are usually closed to each other. Thus corridors act to separate these spaces. Such differences are analysed to be due to the different perceptions of interpersonal and socio-cultural attributes as intra-family and inter-neighbor relationships or communications.

This study explored the sandplay therapy case of a middle-aged woman having difficulty with interpersonal relationships and wanting to increase her self-identity. The goal of the therapy was to change her relationships with others by self-examination and becoming conscious of her negative animus and femininity in a free and protected space provided by sandplay therapy. Forty-five therapy sessions were held. The client exhibited her lonesomeness and fantasies by making sandtrays of a house she would like to live in, a park she would like to relax at and dreams she would like to fulfill in the initial phase of therapy (1~8, Who am I?). In the intermediate phase of therapy (9~33, Meeting myself), she displayed scenes of her negative self and breaking away from her negative self by making sandtrays of shadows, deaths, creations, a soaring scene and a disappearing alligator. In the final phase of therapy (34~45, Discovery of the real Self), she showed scenes of her meeting a positive self by making sandtrays of hope, coexistence, start, harmony and community. This study showed the effectiveness of sandplay therapy since the client' relationships with others were improved through her self-awareness by sandplay therapy in the free and protected space.

In the present paper, we evaluate the analytic conditional Fourier-Feynman transforms and convolution products of unbounded function which is the product of the cylinder function and the function in a Banach algebra which is defined on an analogue o Wiener space and useful in the Feynman integration theories and quantum mechanics. We then investigate the inverse transforms of the function with their relationships and finally prove that th analytic conditional Fourier-Feynman transforms of the conditional convolution products for the functions, can be expressed in terms of the product of the conditional Fourier-Feynman transforms of each function.

Let C[0, T] denote an analogue of Weiner space, the space of real-valued continuous on [0, T]. In this paper, we investigate the translation of time interval [0, T] defining the analogue of Winer space C[0, T]. As applications of the result, we derive various relationships between the analogue of Wiener space and its product spaces. Finally, we express the analogue of Wiener measures on C[0, T] as the analogue of Wiener measures on C[0, s] and C[s, T] with 0 < s < T.

This study aims to view the architectural space of the postmodern era as a concept of continuous change without being fixed, and to understand the spatial elements in architecture with a changing network of relationships. The purpose of the study is to analyze the spatial composition strategies of the two architects while revealing the spatial characteristics shown in Rem Kolhaas and SANAA's works in terms of relativity. The method of the study defines the meaning of non-fixed relationships through theoretical considerations of relativity and then looks at the architectural approaches of Rem Kollhaas and SANAA. The relationship was divided into programs, environments, users, and furniture and furniture in the space and analyzed the works of the two architects. As a result, both architects are similar in that they reject rigid programs by organization and use potentially inherent relationships for building space activation purposes, while Rem Koolhaas uses the user's behavior-inducing strategy, while SANAA uses the user's relaxation strategy.

In this paper, we establish several basic formulas among the double-integral transforms, the double-convolution products, and the inverse double-integral transforms of cylinder functionals on abstract Wiener space. We then discuss possible relationships involving the double-integral transform.
