We prove non-existence of real hypersurfaces with Killing structure Jacobi operator in complex projective spaces. We also classify real hypersurfaces in complex projective spaces whose structure Jacobi operator is Killing with respect to the k-th generalized Tanaka-Webster connection.

The research was investigated and analysed to get basic data which was made outside environment at apartment house complex. The subject of research is housing complex in Japan. Result of research is as following. 1) The house environment is amenity, because they developed the space as green area and open space without developing outside space as a parking lot. 2) They have developed an apartment design variously. it has variety that the design of facets colors, roof forms, attached facilities etc. 3) Housing complex's center axis is needed to make a plan, that a pedestrian passage which is rich in green area is better than a road.

Let M be 3 Semi-invariant submanifold of codimension 3 with lift-flat normal connection in a complex projective space. Further, if the mean curvature of M is constant, then we prove that M is a real hypersurface of a complex projective space of codimension 2 in the ambient space.

This study focused on the analysis of residential satisfaction depending on the extent of the application of environmental-friendly elements on the outdoor space of the apartment complexes. The purpose of this study is to present the basic materials of the environmental-friendly outdoor space planning of residential complexes. The major findings of the study are as follows. First, the results of the comparative analysis of the satisfaction of the outdoor space of apartment complexes show that the complexes with the most application of environmental-friendly elements had higher residential satisfaction. But, there was no meaningful statistical difference between the complexes with the highest level of application of the environmental-friendly elements and the complexes with medium level of application. Secondly, according to a comparative analysis, the overall residential satisfaction of the apartment complex was the same as the residential satisfaction of the outdoor space. Therefore, the overall satisfaction of the apartment complex seems to be influenced by the satisfaction of the outdoor space. Thirdly, the results of the correlative analysis of the satisfaction of the apartment complex showed that the satisfaction of the apartment complex increases as the satisfaction of the outdoor space of the apartment complex increases. The results of this study can be used as the basic materials for environmental-friendly outdoor space planning of apartment complexes.

According to "The regulations regarding the residential construction standards", residents' common spaces are restricted by the standards on building facilities. In a typical apartment complex, residents' communal facilities are represented by a children's playground, a elderly social station, and a management office. However, these residents' communal facilities do not reflect residents' composition characteristics. Multidisciplinary research and experimentation to enable the community of housing complex are being actively conducted. In these situation, we observed institutional improvement about installing standard of community space, and analysed the tendency. The purpose of this study is to propose practical institutions to review the institutional improvement. We conducted a case study where was renovated the community space according to the new standard. As a results, the installing standard of the community space has changed in the direction to increase the autonomy of resident. These results raise the practical performance of the community space, and it has the effect of increasing the satisfaction of the residential environment. The results of this study suggest an alternative to the institutional aspects and planning aspects for community activation in housing complex.

With the rate of spread of motors rapidly increased, but parking difficulties in an apartment complex was aggravated due to an insufficient parking lot. Visual interference on residential environment, various kinds of pollution and noise, decrease of open space in an apartment complex are also causes of parking difficulties. Therefore, this study is to suggest a theory of desirable direction for planning of the parking space by studying psychological characteristics of users' behaviors by the type of the circulation of motors and pedestrians. Consideration on the present situation, real conditions of underground parking space and the consciousness and parking habit of residents, the most important problem is required in this study.

We study totally real and complex subsets of a right quarternionic vector space of dimension n + 1 with a Hermitian form of signature (n, 1) and extend these notions to right quaternionic projective space. Then we give a necessary and sufficient condition for a subset of a right quaternionic projective space to be totally real or complex in terms of the quaternionic Hermitian triple product. As an application, we show that the limit set of a non-elementary quaternionic Kleinian group 𝚪 is totally real (resp. commutative) with respect to the quaternionic Hermitian triple product if and only if 𝚪 leaves a real (resp. complex) hyperbolic subspace invariant.

Outdoor space used for leisure life as inhabitantses' recreation and rest area, and night activity is very important space to many apartment complex. Lately, outdoor space is recognized as a very important space in apartment complex. Especially, that outdoor space is frequently used at night despite planning of lighting of current outdoor space is unprepared for the selection of suitable luminaires, arrangement of luminaire and lighting plan. From this point of view, this paper investigated the essence of light in outdoor space and analyzed different outdoor luminous environment. This paper finally suggested recommended level of illuminance and planning of lighting.

다변화된 사회 구조와 취향을 가진 20대라는 새로운 소비계층의 라이프 스타일이 사회 전반적으로 영향을 미치고 있다. 본 논문은 독특한 감성과 개성을 가진 복합문화공간이 곳곳에 생겨나는 현재, 이들의 라이프스타일을 분석하여 복합문화공간 브랜딩을 제안하는 논문이다. 복합문화공간으로는 사운즈 한남을 선정하여 방문자들을 대상으로 한 브랜드 경험 심층 인터뷰와 참여 관찰을 진행하였다. 연구 결과, 사운즈 한남의 감각적인 요인이 시각에 집중되어 있어 청각, 후각적인 요인이 필요하며, SNS를 통한 알맞은 소통 창구를 만들 필요성이 있다고 밝혀졌다. 사운즈 한남은 기존의 복합문화공간과는 다른 다양함을 바탕으로 한 감수성과 휴식, 그리고 콘텐츠라는 특징적 요인을 가지고 있었다. 위와 같은 연구를 통하여 행동과 창의적 사고를 유발하는 공간구성을 통해 영감을 주는 장소로써 기획하는 것이 복합문화공간의 지향점이며 동시에 20대의 라이프스타일을 반영한 효과적인 방법임을 도출하였다.

Purpose: The purpose of this study was to analyze the space planning of the Senior Center which was supplied recently in apartment complex, to activate the spaces suitable for the changes and needs of the elderly and to explore the complex functions as a community space where intergenerational exchanges are possible. In other words, we sought implications for the physical plan of the district as a community base space and searched for improvement plan. Methods: The survey was conducted by five large private sectors of construction, and 10 of them were built after 2010 in an urban area(Seoul). Literature review, data analysis, field survey and interview were used for the research method. Results: As a result, it was difficult to meet the demands of various elderly people in the space planning, program and operation mode at the current level. In particular, the Baby Boomer generation as an active silver generation will not use the Senior Center. Therefore, based on the results of the survey, we propose some of the following about the Senior Center in apartment complex. First, it is necessary to change the term "the Senior Center" as defined in Article 55-2 of the "Regulations on Housing Construction Standards, etc.". Second, the criteria for setting up the elderly complex space should be presented specifically. Third, it is necessary to secure financial resources in operation and management. Finally, it is necessary to support the residents' organization for community revitalization. Implication: Through the amendment of the laws, it will be possible for various generations to have opportunities to interact by activating the existing community spaces for seniors. It will also contribute to improving the community of apartment complexes.
