  • The residential environment is a place which reflects the gradual evolution of human consciousness because it is a cultural space the term, 'houses' is not relevant in this context as it literally means 'contains'. The long history of human living habits cannot be 'contained' within a space, but can be 'expressed' by a space and by the way the space is used. Furthermore, due to the way it is typically constructed, the basic characteristics of the house usually cannot be rapidly changed to accommodate new habits. However, recent changes that have taken place to the characteristics of the traditional master room suggest that traditional societal values associated with patriarchy have diminished. The current trend where priority is given to children's education also affects such a change. Existing researches related to the master room is confined to the behavioral use of the space and the composition of the physical space, while research on the master room its plane type has not been carried out. Therefore, in this study, apartment model houses are selected, and are classified according to the types of master room. An analysis is then carried out of the master room based on the occupants' requirements in terms of consciousness. Any planning modifications where required are then suggested. This research comprises the followings stages. First, an examination is carried out of existing research on the master room in order to understand its background and spatial components. A definitiones of related terms is also provided. Second, an analysis is carried out of the model houses exhibited at Suwan District, examining the typical standard that has been selected for the master room. Third, an analysis is conducted of the topics and questions to be selected for a questionnaire. Fourth, an analysis is carried out of the consciousness, satisfaction and requirements of the residents, as respondents in the questionnaire, related to the master room. and Research is then conducted of the architectural methods for planning the master room. Finally, future countermeasures for planning the master room are described based on the above analysis and research findings.

  • The purpose of this study is to re-interpretate the meaning of place from the perspective view of events. In the realm of events, time, process, and evolution are emerging as more important elements for better places rather than space or fixed physical elements. First, this study reviews the phenomenological contribution to the meaning of place by discussing differences between positivism and phenomenology. The phenomenological approach has strengths that can perceive individual experiences and idiosyncraises through a holistic approach and qualitative methods. However, it has weaknesses such as unpredictability, subjectivity and ambiguity. In order to overcome these weaknesses, the notion of singularities(pure events) on the metaphysical plane existing between nature and culture is explored via Deleuzean concepts(Post-structuralism); singularities become events(simulacre) through ´becoming´ and these events have meaning through this process in the particular place. By this process, the subject an feed a sense of place through this meaning. Events unexpectedly create a series of events and have impact in the future. Creating various events in the particular place requires many contextural settings where the embodied perceptions could take place. Describing the potentiality of embodied perceptions demands ´smooth space´ rather than ´striated space´. Smooth space refers to the space where orientations and linkages are in continuous variation. Recent architectural and landscape architectural design projects reveal that the emphasis is placed on the open-ended set of various events unfolding over time rather than the physical settings of the place. For better landscape design, new concepts need to be introduced and implemented. These new concepts should focus on creating a series of events and considering the evolution of the place over time through multi-contextural and rhizomatical synthesis rather than rigid and static master plan of SAD(survey-analysis-design) methodology.

  • Background: Mandibular setback surgery can change the position of the mandible which improves occlusion and facial profile. Surgical movement of the mandible affects the base of the tongue, hyoid bone, and associated tissues, resulting in changes in the pharyngeal airway space. The aim of this study was to analyze the 3-dimensional (3D) changes in the hyoid bone and tongue positions and oropharyngeal airway space after mandibular setback surgery. Methods: A total of 30 pairs of cone-beam computed tomography (CBCT) images taken before and 1 month after surgery were analyzed by measuring changes in the hyoid bone and tongue positions and oropharyngeal airway space. The CBCT images were reoriented using InVivo 5.3 software (Anatomage, San Jose, USA) and landmarks were assigned to establish coordinates in a three-dimensional plane. The mean age of the patients was 21.7 years and the mean amount of mandibular setback was 5.94 mm measured from the B-point. Results: The hyoid bone showed significant posterior and inferior displacement (P < 0.001, P < 0.001, respectively). Significant superior and posterior movements of the tongue were observed (P < 0.05, P < 0.05, respectively). Regarding the velopharyngeal and glossopharyngeal spaces, there were significant reductions in the volume and minimal cross-sectional area (P < 0.001). The anteroposterior and transverse widths of the minimal cross-sectional area were decreased (P < 0.001, P < 0.001, respectively). In addition, the amount of mandibular setback positively correlated with the amount of posterior and inferior movement of the hyoid bone (P < 0.05, P < 0.05, respectively). Conclusion: There were significant changes in the hyoid bone, tongue, and airway space after mandibular setback surgery.

  • The determination of three dimensional parameters (e.g., radial speed, angular width, source location) of Coronal Mass Ejections (CMEs) is very important for space weather forecast. To estimate these parameters, several cone models based on a flat cone or a shallow ice-cream cone with spherical front have been suggested. In this study, we investigate which cone model is proper for halo CME morphology using 33 CMEs which are identified as halo CMEs by one spacecraft (SOHO or STEREO-A or B) and as limb CMEs by the other ones. From geometrical parameters of these CMEs such as their front curvature, we find that near full ice-cream cone CMEs (28 events) are dominant over shallow ice-cream cone CMEs (5 events). So we develop a new full ice-cream cone model by assuming that a full ice-cream cone consists of many flat cones with different heights and angular widths. This model is carried out by the following steps: (1) construct a cone for given height and angular width, (2) project the cone onto the sky plane, (3) select points comprising the outer boundary, (4) minimize the difference between the estimated projection points with the observed ones. We apply this model to several halo CMEs and compare the results with those from other methods such as a Graduated Cylindrical Shell model and a geometrical triangulation method.

  • An efficient laparoscope manipulator robot was designed to automatically control the position of laparoscope via a passive joint on end-effector position. The end position of the manipulator is controlled to have corresponding velocity defined in the global coordinate space using laparoscopic visual information. Desired spatial position of laparoscope was derived from detected positions of surgical instrument tips, then the clinical viewing plane was moved by visual servoing task. The laparoscope manipulator is advantageous for automatically maintaining clinically important views in the laparoscopic image without any additional operator. A laparoscope is mounted to a holder which is linked to four degree of freedom manipulator via universal joint-type passive rings connection. No change in the design of laparoscope or manipulator is necessary for its application to surgery assistant robot system. Expanded working space and surgical efficiency were accomplished by implementing slant linking structure between laparoscope and manipulator. To ensure reliable positioning accuracy and controllability, the motion of laparoscope in an abdominal space through trocar was inspected using geometrical analysis. A designed laparoscope manipulating robot system can be easily set up and controlled in an operation room since it has a few subsidiary devices such as a laparoscope light source regulator, a control PC, and a power supply.

  • 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.

  • The paper-folding effect of origami signifies a planarization of the body which questions the three dimensional construction of the body in a more conventional clothing system. Un-structured, variable space posited between the body and clothes, and an absence of gender identification characterizes the planarization of the body. Origami inspiration in fashion stresses a will-to-form rather than mere bodily proportion and structure, which explores a trans-extensity that goes beyond the boundary of the body. This study inquires on the influence of origami as a method to create new vestmental space in contemporary fashion. The flat-plane clothes of origami-inspired design are no longer cut to the body and the clothes could be altered by the wearer. The space is introduced in between a three-dimensional dress-body and the body. Origami-inspired design in Japanese avant-garde fashion deconstructs the convention and promotes a symbiosis of body and clothing instead. The shape of the body is completely estranged by three-dimensional sculptures, alluding to the paper folds of origami and the movement of the body that are transmitted to the clothing through fine folding that transform into an unexpected event.

  • 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 stage space in theatre for the performance of a play requires two aspects of the physical space for a play and the image as the background or the theme of a play. This research focuses on the scene design that creates the background or the theme of a play and communicates it to the audience. The scene design is composed of various design elements of space and objects as the properties of a play. Design elements and the objects are the design languages in various form; plane, three-dimensional, multi-dimensional form. These design language have the significant meaning as a sign like human language. The scene design is completed with rhetorical expression for communication in theatre. This research defines the category of meaning that design elements of scene design can create and the rhetorical expression of the scene design language. King Lear directed by Robert G. Anderson was analyzed with the category of design elements as a sign and the pattern of the rhetorical expression. The scene design for a play is completed effectively by the rhetorical expression of design elements as the design language for communication with the audience in theatre.

  • Let Hg and Dg be the Siegel upper half plane and the generalized unit disk of degree g respectively. Let C(h,g) be the Euclidean space of all $h{\times}g$ complex matrices. We present a partial Cayley transform of the Siegel-Jacobi disk Dg×C(h,g) onto the Siegel-Jacobi space Hg×C(h,g) which gives a partial bounded realization of Hg×C(h,g) by Dg×C(h,g). We prove that the natural actions of the Jacobi group on Dg×C(h,g). and Hg×C(h,g). are compatible via a partial Cayley transform. A partial Cayley transform plays an important role in computing differential operators on the Siegel Jacobi disk Dg×C(h,g). invariant under the natural action of the Jacobi group Dg×C(h,g) explicitly.
