The purpose of this study is to grasp the present state of a outdoor space planning and to analysis plan characteristics in based on regional characteristics in Housing complex plan. The analysis result of this study is as follows : first, we know that the right of regional characteristics is appearing variously every research workers. also an analysis about regional characteristics that should be considered in housing complex plan was insufficient. Second, regional characteristics can be classified into 5 factors. These are classified as a context of location, city link, life atmosphere, needs of locals and creation of image. Third, it has originality against other housing complex to graft items connected with 'U contest' on outdoor space planning. Also, it has affirmatively effected on image of Buk-gu and recognition of Dong beyn-dong and Seo beyn-dong. It is get out of the uniform design by a planning based on land and surrounding environment in arrangement and forms. Also residents have the satisfaction and pride in arrangement considering the climate of a region and security of the green space.

The purpose of this study is to accumulate basic data to establish planning direction and planning factors for the environment-friendly apartment complex. For this purpose, the survey has been conducted to residents living in an apartment housing and graduate students, architects and research experts in the field. The major findings of this study are as follows; 1) The basic concept of planning factors for environment-friendly apartment complex are energy saving, resources saving, minimizing environment pollution, natural harmony, regional identity and pursuit of residents' health & amenity. 2) For the planning factors of environment-friendly apartment complex, the residents had a great regard for aspect of Low-Impact (energy saving, resources saving, minimizing environment pollution). The experts, on the other hand, had a great regard for aspect of High-contact (natural harmony, regional identity). 3) It was increase of prime cost that the residents and experts regarded as the most important problem of planning and purchasing of environment-friendly apartment. It thus appears that the promotion of environmental consciousness of residents taking in the portion of increased cost is crucial parts and also that the role of the connected aspects such as administration, construction companies and residents must be redefined in order to manage problems caused in process of the development of it.

The effects of $\alpha$- and $\beta$-cyclodextrins (CD) on the twisted intramolecular charge transfer (TICT) behavior of p-N,N'-dimethylaminobenzoic acid (DMABA) in buffered aqueous solution have been investigated by examining formation and decay behaviors of the TICT-typical dual fluorescence. The ratio of the TICT emission to the normal emission (I$_a$/I$_b$) increases linearly $\alpha$-CD concentration increases, while in the presence of $\beta$-CD it shows nonlinear dependences on the CD concentration. The analysis of the CD-dependent changes of the I$_a$/I$_b$ and absorption spectra demonstrates formation of 1:1 inclusion complexes between DMABA and CDs. The decay time of the normal emission (ca. 700 ps) is little affected by the formation of $\alpha$-CD inclusion complex, whereas it increases upto ca. 1.6 ns upon formation of $\beta$-CD inclusion complex. The TICT emission for the $\beta$-CD inclusion complex exhibits two decay components while it shows a single component for the $\alpha$-CD inclusion complex, indicating formation of one or two types of inclusion complex in the presence of $\alpha$-CD or $\beta$-CD, respectively. These results are attributed to the CD cavity size dependence on patterns of complexation between CDs and DMABA. The CD size dependences of the TICT fluorescence properties with the orientation of the guest molecule demonstrate that the specific hydrogen bonding between the carboxylic acid group and water plays an important role in the excited-state TICT.

After 2004, as the community mixed-support facility in Japan was admitted as a private business of public facilities based on the Special Law for Urban Regeneration, the community mixed-support facilities in Japan are developed into various types with the view of the urban regeneration and urban renewal, more different point of view, and a tendency of establishment of the community facility has been considerably changed for the past twenty years. The reasons of the change are the social demand for the reformation of facility and the modification of subsidy constitution according to the establishment of equal facility. Some examples of that are the construction of lifelong education community and the change into a equivalent society between male and female and the adjusting to the aging and the welfare society and the social situation of more consumption recently, and in order to emerge from former building system, new facilities related to the contents are being expanded. The complex of the community mixed-support facility has an advantage in that it supplies the services for the complex of the community mixed-support facility, constitutes the communal character and the sense of solidarity among residents and can lead the development of region through the exchange of regional information. Through the Japanese community mixed-support facility which has many cases of it, this study would recognize the suggestion, the feature of it and examine the complex types.

Purpose: As the connection between physical and non-physical structures in cities is expanding and becoming more complex, the risk of complex disaster which causes damage in a complex way is increasing. Preparing for these complex disasters, it is important to preemptively identify and manage disasters that can develop into complex disasters. Therefore, this study analyzes the disaster types studied as complex disasters by analyzing the trends of domestic and international studies related to complex disasters, and presents the direction of complex disaster management in the future. Method: We first established co-occurrence networks between disaster types based on 993 articles related to complex disasters published in disaster-related journals for the last 20 years (2002-2021). Then, through network analysis, domestic and international complex disaster research trends were compared and analyzed. Result: Research on complex disasters related to storm and flood damage, infrastructure failure and fire was high in domestic studies, and it was analyzed that research on complex disasters related to earthquakes and landslides has recently increased. However, in international studies, the proportion of studies on infrastructure failure along with storm and flood damage and earthquake was high, and various types of disasters such as tsunami and drought appeared. Conclusion: The results of this study are expected to increase the understanding of the trends in complex disaster research and provide suggestions of domestic complex disaster research in the future.

Characteristics of color application indicated from Kirchsteigfeld is presented the various points of view to be preserved urban housing color. It had been handled as environmental color by view point of community and connectivity rather than color scheme of single housing. First, color to be consisted of basis for urban entirely as background color in urban housing complex has been indicated the bright and cheerful feelings and expressed to be introduced mostly from the single color system. Second, characteristics to be inhibited strongly from housing complex had been indicated by restricted four types of color, formulated the overall context and change through accent and the change from disposition of principal and the accessary of color scheme. In this case, it was not regular formulation, but as a whole category view, it could be provided by orderly regularity system strictly Particularly it had been applied as a whole for lightness change by single color, introduced the different color of building to be centered or remained by a visual point. This had been formed to introduction of color by stand points of housing group not introduction to color by sole concept of building. Third, emphasizing of morphologic feeling by using of difference of lightness, it could be indicated the mild and comfortable stereo-type sensibility from the overall types of housing, we could understand for formation of color code by lightness of slightly differences. Fourth, it had been taken the convenient adaptation method for maintenance of simple graphic system as a environmental color. It has considerable advantage for sustainability of color to indicate on finishing material, form and detail in architecture, as the sole separated color not to be complicated when to be painted over and again or managed continuously.

This study examines multiple functions of the complex cultural center. Recently, the importance of the complex cultural center has been growing, as peoples desire for cultural activities diversified. In order to effectively accommodate the general publics interests in various cultural activities, the complex cultural center tended to be multi-functional. At the same time, I argue that it is necessary to reexamine its functions in terms of how the multi-complex cultural center fits into local environment. Only when both peoples demand and local environment are fully integrated into its design, can the multi-complex cultural center accomplish the goal of multiple functions in a true sense.

Let M be a real hypersurface of a complex space form with constant curvature c. In this paper, we study the hypersurface M admitting Miao-Tam critical metric, i.e., the induced metric g on M satisfies the equation: $-({\Delta}_g{\lambda})g+{\nabla}^2_g{\lambda}-{\lambda}Ric=g$, where ${\lambda}$ is a smooth function on M. At first, for the case where M is Hopf, c = 0 and $c{\neq}0$ are considered respectively. For the non-Hopf case, we prove that the ruled real hypersurfaces of non-flat complex space forms do not admit Miao-Tam critical metrics. Finally, it is proved that a compact hypersurface of a complex Euclidean space admitting Miao-Tam critical metric with ${\lambda}$ > 0 or ${\lambda}$ < 0 is a sphere and a compact hypersurface of a non-flat complex space form does not exist such a critical metric.

A fuzzy logic filter is constructed from a set of fuzzy IF-THEN rules which change adaptively to minimize some criterion function as new information becomes available. This paper generalizes the fuzzy logic filter and it's adaptive filtering algorithm to include complex parameters and complex signals. Using the complex Stone-Weierstrass theorem, we prove that linear combinations of the fuzzy basis functions are capable of uniformly approximating and complex continuous function on a compact set to arbitrary accuracy. Based on the fuzzy basis function representations, a complex orthogonal least-squares (COLS) learning algorithm is developed for designing fuzzy systems based on given input-output pairs. Also, we propose an adaptive algorithm based on LMS which adjust simultaneously filter parameters and the parameter of the membership function which characterize the fuzzy concepts in the IF-THEN rules. The modeling of a nonlinear communications channel based on a complex fuzzy is used to demonstrate the effectiveness of these algorithm.

In this paper, a complex fuzzy adaptive decision feedback equalizer(CFADFE) based on the LMS algorithm is proposed. The propoed equalizer is based on the complex fuzzy adaptive equalizer. The CFADFE isconstructed from a set of changeable complex fuzzy IF-THEN rules, where the 'IF' part of the rule is characterized by the state from a set of changealble complex fuzzy IF-THEN rules, where the 'IF' part of the rule is characterized by the state of the desision feedback. the role of decision feedback is to reduce the computational complexity. Computer simulation of the decision feedback. The role of decision feedback is to reduce the computational complexity. Computer simulation shosw that the CFADFE notonly reduces the computational complexity but also improves the performance compared with the conventional complex fuzzy adaptive equalizers. We also show that the adaptation speed is greatly improved by incorporating some linguistic information about the channel into the equalzer. It is applied to M-ary QAM digital communication system with linear and nonlinear complex channel characteristics.
