In the paper [12] we have introduced the new kind of pseudo-einstein ruled real hypersurfaces in complex space forms $M_n(c), c\neq0$, which are foliated by pseudo-Einstein leaves. The purpose of this paper is to give a geometric condition for non-proper pseudo-Einstein ruled real hypersurfaces to be totally geodesic in the sense of Kimura [8] for c> and Ahn, Lee and the present author [1] for c<0.

Recent advancement in information technology requires new interpretations for the space among human, machines and environment. Investigation of space between information and human could lead to the proper ways, in which human and machines meet. Various concepts regarding space have been explored in terms of “virtual reality in cyberspace” and “embodiment in tangible space.” “Mom (embodiment),” space, virtuality, sensation/perception, and interactive technology are some of the key ideas to be explored. Human “Mom” is such a fundamental membrane through which human can interact with the environment physically and mentally. An embodied interaction paradigm, based on “Mom,” is investigated. This leads to interactive technology paradigm. Sound space is an invisible but a tangible space in a sense that it travels in emotional tremors and stimulates new sensations and perceptions. Three cases are introduced to experiment such tangible space as a new and proper interactive paradigm. Also, a historical model of interaction is reviewed, which includes electrical, symbolic, textual, graphical, tangible, and social interaction.

We give general fixed point theorems for compact multimaps in the "better" admissible class $B^{K}$ defined on admissible convex subsets (in the sense of Klee) of a topological vector space not necessarily locally convex. Those theorems are used to obtain results for $\Phi$-condensing maps. Our new theorems subsume more than seventy known or possible particular forms, and generalize them in terms of the involving spaces and the multimaps as well. Further topics closely related to our new theorems are discussed and some related problems are given in the last section.n.

From being understood as a dwelling, the concept of home is extended to denote belongingness and a sense of attachment in which spiritual, ethnic, religious and historical identities shape a sense of self. Hence, home with its expanded definitions is considered as a cross-cutting and fundamental theme in works by Võ Phiến, one of the diaspora's towering minds who devoted his life to capturing the rich details of Vietnamese culture, its villages and locals. This article pays attention to the cultural space created through Võ Phiến's tuỳ bút written when he lived in Saigon and California. Many representations of home were argued as evidence of subtle influences of the historical and social context on the way Võ Phiến perceived and built his own homeland. By observing disruption and continuity through the expressions of the home in Võ Phiến's writing, we shed light on how Võ Phiến managed to create an indigenous cultural space towards social interactions of Western ideology in South Vietnam from 1964 to 1975.

Bad weather conditions such as haze lead to a significant lack of visibility in images, which can affect the functioning and reliability of image processing systems. Accordingly, various single-image dehazing (SID) methods have recently been proposed. Existing SID methods have introduced effective visibility improvement algorithms, but they do not reflect the image's perspective, and thus have limitations that distort the sky area and nearby objects. This study proposes a new SID method that reflects the sense of space by defining the correlation between image brightness and haze. The proposed method defines the haze intensity by calculating the airlight brightness deviation and sets the weight factor of the depth map by classifying images based on the defined haze intensity into images with a large sense of space, images with high intensity, and general images. Consequently, it emphasizes the contrast of nearby images where haze is present and naturally smooths the sky region to preserve the image's perspective.

본 노문에서는 말뭉치와 개념정보에 기반한 명사 중의성 해소 방법을 제안하다. 지곤의 연구에서는 대부분 어휘의 공기 정보을 이용하고있으나, 이러한 방법은 많은 저장공간이 필요하고, 적용률이 크지 않다는 단점이 있다. 본 논무에서는 자동으로 의미 태깅된 한국어 말뭉치에서 추출된 공기 개념정보를 이용하여 명사 중의성을 해소하는 방법을 제안한다. 제안한 방법의 평가 실험에서 기본의미를 정하는 것보다 1.6% 높은 평균 82.4%의 정확률을 보였다. 실험 문장들이 학습문장과 다른 것을 고려하면, 제안된 방법이 어휘 중의성 해소에 유용함을 보여주는 결과라고 할 수 있다.

In 1994, Songbuk-gu Office of Seoul held a design competition for Miarigogae-Park, Miarigogae has a special sense of place. It was a place where bararians had crossed the boundary to this country during the Manchu war of 1636. It was a public cemetery where only Koreans had been buried under the rule of Japanese imperialism. It was a place where national patriots had been kidnapped to the North during the Korean War. It's sorrows have been sung in the name of song-'Danjangeui-Miarigogae'(one of the most popular song in Korea). It's sense of place has been kept in every Korean people's mind in the form on 'non-physical image'. Even though, the site itself was a small space - only 1000㎡, the meaning of park-making was very significant. It meant that it would create a physical 'setting' to express the sense of place which has been existed only in our mind as a form of 'non-physical image'. In the winning scheme proposed by the author, the sense of place of Miarigogae was expressed in the form of 'castle walls' which could be easily come into everyone's mind as an image of war. The scope of work also included a crossing bridge and symbolic features. It was meaningful that a landscape architect won the competition including on those items which were not usually handled in pure landscape architectural offices. The purpose of this paper was to articulate the concept of the winning entry in detail and to describe how the concept actualized in reality.

최근 자연어 처리 문제에서의 단어 임베딩은 아주 큰 주목을 받고 있는 연구 주제이며 스킵그램은 성공적인 단어 임베딩 기법 중 하나이다. 주변단어들 정보를 이용해서 단어들의 의미를 학습하여 단어 임베딩 벡터를 할당하며 텍스트 자료를 효과적으로 분석할 수 있게 한다. 그러나 벡터 공간 모델의 한계로 인해 기본적인 단어 임베딩 방법들은 모든 단어가 하나의 의미를 가지고 있다는 것을 가정한다. 다의어, 즉 하나 이상의 의미를 가진 단어가 실생활에서 존재 하기 때문에 Neelakantan 등 (2014)은 군집분석 기법을 이용하여 다의어의 여러 의미들에 해당하는 의미 임베딩 벡터를 찾기 위해 MSSG (multi-sense skip-gram)를 제안했다. 본 논문에서는 MSSG의 통계적 성능을 개선시킬 수 있는 변형된 MSSG 방법을 제안한다. 먼저, 가중치를 활용한 가중문맥 벡터를 제안한다. 나아가, 군집의 수, 즉 다의어의 의미 수를 자료에서 자동적으로 추정해주는 x-means 방법을 활용한 알고리즘을 제안한다. 본 논문에서 수행한 실증자료를 기반한 모의실험에서 제안한 방법은 기존 방법에 비해 우수한 성능을 보여주었다.

This study is to analyze a case of US Bravo TV program, Interior therapy with Jeff Lewies, based on analytical psychology by Carl Jung, to understand characteristics of interior therapy in psycho-therapeutic viewpoint. Case study among descriptive observation approaches was chosen as a study method while the study range was set as 8 episodes in 2012 and 8 episodes in 2013. As a result of study, future application of therapy to domestic interior design was suggested as 3 types the following; a) Paranoid and storage disorder type that pursues space design by horizontal elements with a sense of comfortable, starting from throwing things away, and suggests whiteness based on desire to be cleaned; b) Individual taste type starting from give and take between members and recognizing one another. e.g., aligning the U-shaped sofa and giving a sense of comfort by using the achromatic colors; and c) Workroom type involved with the face-to-face type of space design and arrangement of mild grey and brown colors. Finally, this study has its significance in suggesting the direction for new occupational clusters in the field of domestic space design (interior, architecture, environment design, etc.), which could be utilized as a basic data for training program development to foster interior therapy professionals.
