Purpose: This study presents the results of the analysis on space utilization of kidney dialysis units in regional public hospitals, which plays a key role in local public medical services. The result aims to achieve safety from infection, allow comfort for the dialysis environment, and stability for medical support. The purpose of this study is to present fundamental data for architectural plans for the kidney dialysis unit, as well as to alleviate potential infectious diseases such as COVID-19. Methods: For research purposes, the investigation and analysis of space utilization were based on architectural floor plans, research papers and literature, related legal systems, and public statistics. Of the main 35 regional public hospitals, in regards to data accessibility, 15 facilities were selected to conduct the survey and analysis for the objective. Results: The space composition by area research results of kidney dialysis units in public hospitals are as follows: Firstly, most targets do not have required rooms in the access and support area, except for the hemodialysis beds in the treatment section. Secondly, the access area requires necessary room and space design that took into consideration of convenience and accessibility for patients. Thirdly, in regards to infection prevention and control, proper circulation and room plan is essential for storage and disposal of contaminated products and linen after use. For the treatment area, the arrangement plan needs to establish a visual connection between the isolation room, the nursing station, and the bed area. Additionally, consideration of circulation in the preparation, treatment, observation, examination, and all other rooms in the facility is required. Lastly, for the support area, the room is designed to consider adequate working and meeting spaces for the medical staff, consultation space for patients or guardians, separate storage and disposal of clean and contaminated items, and the storage of various equipment for dialysis. Implications: In preparation for the increase in chronic kidney failure patients and the spread of infectious diseases, such as COVID-19, the researched data demonstrates the basic guidelines for space composition of kidney dialysis units and the significant role of regional public hospitals.

In this paper, we intend to demonstrate a new intuitive force-feedback device for advanced VR applications. Force feed-back for the device is tension based and is characterized by 7 degrees of freedom (DOF); 3 DOF for translation, 3 DOF for rotation, and 1 DOF for grasp). The SPIDAR-G (Space Interface Device for Artificial Reality with Grip) will allow users to interact with virtual objects naturally by manipulating two hemispherical grips located in the center of the device frame. We will show how to connect the strings between each vertex of grip and each extremity of the frame in order to achieve force feedback. In addition, methodologies will be discussed for calculating translation, orientation and grasp using the length of 8 strings connected to the motors and encoders on the frame. The SPIDAR-G exhibits smooth force feedback, minimized inertia, no backlash, scalability and safety. Such features are attributed to strategic string arrangement and control that results in stable haptic rendering. The design and control of the SPIDAR-G will be described in detail and the Space Graphic User Interface system based on the proposed SPIDAR-G system will be demonstrated. Experimental results validate the feasibility of the proposed device and reveal its application to virtual reality.

This paper suggests a relative orbit control strategy for the CubeSat Astronomy by NASA and Yonsei using Virtual Telescope Alignment eXperiment (CANYVAL-X) mission whose main goal is to demonstrate an essential technique, which is an arrangement among two satellites and a specific celestial object, referred to as inertial alignment, for a next-generation virtual space telescope. The inertial alignment system is a relative orbit control system and has requirements for the relative state. Through the proposed orbit control strategy, consisting of separation, proximity keeping, and reconfiguration, the requirements will be satisfied. The separation direction of the two CubeSats with respect to the orbital plane is decided to provide advantageous initial condition to the orbit controller. Proximity keeping is accomplished by differential atmospheric drag control (DADC), which generates acceleration by changing the spacecraft's effective cross section via attitude control rather than consuming propellant. Reconfiguration is performed to meet the requirements after proximity keeping. Numerical simulations show that the requirements can be satisfied by the relative orbit control strategy. Furthermore, through numerical simulations, it is demonstrated that the inertial alignment can be achieved. A beacon signal had been received for several months after the launch; however, we have lost the signal at present.

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.

The purpose of this study is to examine residents' perception and needs for storage according to the family life cycle. In order to achieve our goal, the questionnaire survey is used. We sample the questionnaire surveys of 250 apartment households in Seoul. The data collect by the questionnaire survey was analyzed by examining the frequency, percentage on the SPSS/PC+ Statistics package. The results of the study are obtained as follows: 1) In research on the actual storage condition, residents tend to feel constraint on storage of the season goods and the storage satisfaction on the service area is founded lowest. Therefore, it is needed more efficient space plan on the balcony storage and the interior storage for the season goods. 2) In research on the storage consciousness and attitude, residents tend to keep the goods of no use and prefer to arrange neatly rather than use conveniently. Therefore, it is needed more efficient space in the balcony for the storage of the goods of no use and the colsed furniture rather than the open furniture is suited for arrangement. 3) In research on the storage needs, needs for the built-in furniture in all family life cycle show highly and residents want to a space for the exclusive use of the storage. In a solution, we propose to equip with the interior storage and the exterior cooperative storage

어둡고 한정된 지하공간의 이미지의 개선은 지하개발 성공여부에 중요한 결정요소가 되고 있다. 주거단지 지하주차장의 조명환경은 지금까지 양적 위주의 설계와 운영이 이루어졌으나 이제는 지하주차장 공간의 질적 향상이 필요한 때이다. 이를 위해서 우선 고려해야 할 두 가지는, 첫째로 주차장에서 주로 사용되는 광원에 대한 이해이며, 둘째는 균제도의 향상이다. 특히 겨울철 외기의 영향에 의한 주차장 실내의 심각한 조도저하와 균제도의 유지를 위한 방안이 마련되어야 한다. 따라서 조명기구의 간격, 배열에 대한 변화가 필요하며, 운용에 있어서는 시간에 따른 일률적인 기존의 제어방법에서 벗어나 이용패턴을 고려한 방식으로의 전환이 요구된다.

The Program from modern architecture is an indispensable condition which must put in all buildings today and it is a relationship setting of a various functions. According to changing society consequently, a complicated form and program in modem appear again. Through this background from, we intend to observe the meaning which the program is having in the construction in this manuscript. Sejima is the architecture who try to use variously special formation of the program. Specially, we are planning to research the quality which his program is haying form Sejima's architecture and how it is reflected ill this construction. Resultantly, each program which appears from Sejima's architecture makes a gap space and irregular arrangement. The characters of the space which is put each through the gap don't have a deceptive plan each other and they are compounded. Also, each character to have their territories is intersected and putting out of the various features in the program coat. First, form of the maze plane, Intersecting each territory. Second, forming the territory as fitting their act oneself in the space where can be existing. Third, having more interest in the event that happens inside than existence problem of thing.

The origin of the Roman public basilica is Rome's indigenous style morphologically but actually it seems that developed the Greek semi-open style stoa into the Roman practical interior space. In the early ages, the arrangement of Roman forum had been planned high symbolical temple as the center but gradually changed into the basilica centered which were used often by citizen. Through the Roman period, the important types of early Roman basilica have Fano basilica in the first century BC, Pompei basilica of mid period in the first century AD, Doclear basilica with apse as late type in the second century AD. Pompei type well characterized the feature of Roman public basilica among them. The result of the floor plan analysis shows that the long side access to the interior space is over 76 percent of examples and nearly 70 percent have no apse and the average of vertical horizontal length ratio presents as 1:2.3. The typical plan of Roman public basilica can be defined that most of access are being entered from one of the long side, and most of basilica have no apse, and normally having inner columns arranged in one or more concentric rectangles around nave as a center.

A baffle system for an airglow photometer, which will be on board the Korea Sounding Rocket-III(KSR-III), has been designed to suppress strong solar scattered lights from the atmosphere below the earth limb. Basic principles for designing a baffle system, such as determination of baffle dimensions, arrangement of vanes inside a baffle tube, and coating of surfaces, have been reviewed from the literature. By considering the constraints of the payload size of the KSR-III and the incident angle of solar light scattered from the earth limb, we first determined dimensions of a two-stage baffle tube for the airglow photometer. We then calculated positions and heights of vanes to prohibit diffusely reflected lights inside the baffle tube from entering into the photometer. In order to evaluate performance of the designed baffle system, we have developed a ray tracing program using a Monte Carlo method. The program computed attenuation factors of the baffle system on the order of $10^{-6}$ for angles larger than $10^{\circ}$, which satisfies the requirements of the KSR-III airglow experiment. We have also measured the attenuation factors for an engineering model of the baffle system with a simple collimating beam apparatus, and confirmed the attenuation factors up to about $10^{-4}$. Limitation of the apparatus does not allow to make more accurate measurements of the attenuation factors.
