The challenge to be faced in public transportation today is to satisfy human needs with the least delay, with the smallest number of accidents, and with the most economic use of energy, space, materials, man-power and money. One possible solution may lie in city train system, including AGT system. Specially, Passenger space in AGT is important to balance the budget of layout with passenger's satisfaction. This study focuses on lay-out and space, comfort which should be considered from the conceptual design stage of the interior layout work. Traditionally, the interior layout of the passenger room has emphasized ridequality and style. However, as the train becomes more prevalent and versatile, the focus also tends to shift toward layout and space to have comfortable circumstances. After all, the purpose of this research focused on arrangement a rational interior layout of the train through ergonomics research. Finally, the key was ensuring the comfortable environment based on cultural background of the passenger.

In this work the kinetics of volume changes of fluid spaces associated with infusion of Ringer's solution are analyzed using the body fluid space model. During infusion of Ringer's solution, the human body is assumed to be characterized by the fluid space model into which fluid is fed and from which fluid is left. Various infusion types were tested to accommodate different medical situations. Volunteers were given Ringer's solution and the changes in blood hemoglobin were detected. From the comparison with experimental data, the single- and two-fluid space models were found to represent adequately the kinetics of human volume expansion during infusion of Ringer's solution.

We use three-dimensional magnetohydrodynamic (MHD) simulations of flux emergence from solar subsurface to corona. In our previous work, we reported the relation between magnetic-field configuration and the flux expansion factor. Following these results, we investigate where an upflow is generated in an active region and how its location is related to the flux expansion factor. We also derive physical quantities of a real active region from observation data provided by Nobeyama Radioheliograph (NoRH), X-Ray Telescope (XRT), and Extreme Ultraviolet Imaging Spectrometer (EIS) onboard Hinode. These physical quantities are plasma density, temperature and flow. By comparing the simulation result and observational one, we will discuss the properties of the location producing a solar wind.

In recent decades, underground usage in urban areas has expanded from subways and utilities to include virtually every non-residential building function. Greater usage of underground space is envisioned in the more congested urban areas in the world such as Asia and Europe. This increasing interest in underground development is raising basic questions about whether people can work and live underground, and if so, what design techniques can sucessfully be employed. The actual experience of people in underground space, as well as general associations and image of the underground reveal predominantly negative attitudes. A number of design techniques have been suggested by researchers, or actually utilized by designers, to alleviate these potential problems for people in underground space. This paper identifies these psychological and physiological problems. In addition, design objective and possible solutions are briefly summarized. This is followed by a summary of special design problems and objectives related to road tunnels.

A curve is rectifying if it lies on a moving hyperplane orthogonal to its curvature vector. In this work, we extend the main result of [Chen 2017, Tamkang J. Math. 48, 209] to any space dimension: we prove that rectifying curves are geodesics on hypercones. We later use this association to characterize rectifying curves that are also slant helices in three-dimensional space as geodesics of circular cones. In addition, we consider curves that lie on a moving hyperplane normal to (i) one of the normal vector fields of the Frenet frame and to (ii) a rotation minimizing vector field along the curve. The former class is characterized in terms of the constancy of a certain vector field normal to the curve, while the latter contains spherical and plane curves. Finally, we establish a formal mapping between rectifying curves in an (m + 2)-dimensional space and spherical curves in an (m + 1)-dimensional space.

Ron Arad, the master of contemporary design in the U.K., is one of representative leaders of this age who has left distinguished achievements in the history of contemporary design through innovative design. Analyzing and understanding the Deconstructive design concept and the deconstructive characteristics of interior space of Ron Arad will contribute to finding directions for today's design and laying the ground for explaining the development pattern of design in the 21st century. After analyzing the deconstructive characteristics of each selected space, One Off and Ron Arad Associates have shown a deconstructive design trend of a creative formula by using methods that shed conventional processes and material while a space composition and form of new concept was attempted in the resting space of the New Tel Aviv Opera House, offering not only the establishment of a new circulation system, but also diverse experiences of space to visitors. Likewise, a temporal experience and communication between the user and the space was attempted in Belgo Noord and Belgo Central by partially applying a narrative space composition that sheds existing design concepts. At the Millennium House, they have produced an interior space for future house developed by breaking off from existing typical design development work and material through computer operation, and made various forms of space and atmosphere possible by attempting variable elements and the use of ultramodern material. Y's fashion shop has granted variability to the form and volume of space according to time by presenting display elements that have shed existing form and function. Hotel Puerta America as well, with a curved structure that has broken off with existing forms and maximized space variability through structures that have utilized ultramodern materials and instruments. Through this study, it has been verified that Ron Arad has been unraveling connections between interior space and its user, its requirements, and the original unique principles of space by applying deconstructive design concepts, and that through the mediation of these spaces, he is attempting indirect communication with the user. Eventually, he is taking part in the harmony and development of all elements of space connected with human beings by applying deconstructive design concepts.

This work is a part of our project to establish a Website which provides a list of magnetic clouds (MCs) identified by WIND and ACE spacecraft. MCs are characterized by their magnetic fields that are well described by magnetic flux rope structures, whereas interplanetary coronal mass ejections (ICMEs) are interplanetary manifestations of coronal mass ejections (CMEs), usually identified by differences of plasma and magnetic field characteristics from those in the background solar wind. It is widely accepted that, while MCs are generally identified within ICMEs, the number of MCs are significantly lower than the number of ICMEs. In our effort to identify MCs, however, we have found that there was a big problem in identification method of MCs in previous works. Generally speaking, most of the previous surveys failed in identifying MCs which encounter the spacecraft at large distances from the MC axis, or near the surface of MC structures. In our survey, MCs are identified as the region of which magnetic fields are well described by appropriate flux rope models. Thus, we could selected over 45 MCs, in 1999 solar wind data for instance, while 33 ICMEs are listed in the Website of the ACE Science Center reported by Richardson and Cane.

본 논문은 동양회화(東洋繪畵)에 있어서 경영위치(經營位置)에 의한 여백(餘白)의 미(美)를 두 가지 관점(觀點)에서 고찰하였다. 첫째, 화면구성(畵面構成)의 일환인 경영위치(經營位置)로 드러나는 여백(餘白)의 처리 방법에 대한 기존의 방법론을 사료(史料)를 통하여 분석(分析)하여 체계적으로 정리하였으며, 둘째, 여백(餘白)의 미(美)에 대한 전통적(傳統的) 관점과 본인의 관점을 비교하여 그 차이점을 파악(把握)하였다. 대부분의 선행연구(先行硏究)와 자료(資料)는 여백(餘白)의 운영(運營)과 표현방법이 거의 수묵(水墨), 산수화(山水畵)에 집중되어 있었기 때문에 본인은 채색(彩色)위주의 작업을 하면서 여러 조형요소 가운데 사물간의 구성 및 색채(色彩)간의 조화(調和)를 통한 화면공간의 운용문제에 대해 연구하였으며, 동양회화의 회면구성을 담당하는 경영위치(經營位置) 요소 가운데 여백(餘白)의 미(美)를 새롭게 평가하고 인식(認識)하는 계기를 마련하고자 하였다. 수묵화(水墨畵)와 달리 채색화(彩色畵) 분야에서 제대로 인식(認識)되지 못했던 여백(餘白)의 운용에 대한 표현성의 확대와 그 의미를 살펴보았으며 이를 통해 표현기법이나 표현 언어 측면에서 공통점을 갖는 다른 예술분야(藝術分野)와 연계(連繫)하여 연구 분석함으로써 여백(餘白)의 표현과 그 감상의 경계가 결코 회화(繪畵) 한 분야에만 국한되지 않음을 연구하였다. 여백(餘白)의 개념(槪念) 및 표현방법에서는 여백(餘白)과 공간(空間)의 기본개념을 탐구하고 분석하면서 동양사상(東洋思想) 속에 나타나는 여백개념(餘白槪念)을 정리하였고 경영위치(京營位置)의 형성과 변천을 정리하고 원개념(遠槪念)을 정리하였다. 본인은 작품창작에 있어서 사물의 본질(本質)을 파악하여 표현하기 위한 방법으로 형사적인 측면과 신사적(神似的)인 측면을 함께 고려하였다. 형사적(形似的)인 측면에 해당하는 드러난 형상의 표현은 대체로 격물치지적(格物致知的) 측면을 고려하였으며, 사의적(寫意的) 측면에 해당하는 무형(無形)의 형(形)은 창작 주체의 정신과 합일되는 '물화(物化)'의 경지에 이르고자 노력하였다. 그 안에 내재된 정신성을 표출하기 위하여 장자(莊子)가 제시한 '심제(心齊)'와 '좌망(坐忘)'의 경계를 추구하면서 정신적 수양의 경지에 이르고자 하였다. 정신적 수양이 작품 속에 투영될 때 화면에 외형적인 형태와 더불어 내재된 본질도 함께 전달될 수 있으며 화면 속에 표현된 형상(形象)의 이미지는 현실에서 체득(體得)한 심미적 경험(經驗)을 바탕으로 하는 것이라 보았다. 본 논문은 역대(歷代) 화가(畵家)들과 이론가들이 남긴 역사적(歷史的) 유산(遺産)들을 근거(根據)로 전통(傳統)을 계승(繼承)하고 변호시켜 재창조(再創造)함으로써 본인 작품의 정체성(整體性)을 확립해야 한다는 사실을 알게 되었다. 본인이 추구하고 지향(指向)하는 작품세계의 정체성(整體性)을 확립하기 위해서 전통(傳統)과 현대(現代)를 창조적(創造的)인 방법으로 융화(融和)시켜 향후 작품의 방향성(方向成)을 찾고자 하였다.
