As single-person households increase, demands for self interior design has been also increasing. The furniture arrangement takes big part of interior design. But sometimes people need professional helps for the proper and effective arrangement of furniture which makes self-interior design harder. Often, people share information and advices about interior design through Social Network Service. Experts could help directly but this approach would have several issues: First, the detailed and accurate advice would be difficult because experts have to examine the space through 2D pictures or video. Second, they have to make an appointment which would cause inconvenience to both customer and expert. In this paper, the furniture arrangement application for real-time sharing of interior design based on virtual reality is proposed to make up for the weak points. People can precisely share information and advice about self-interior design through this application in realtime, reducing waste of time and energy.

The rated voltage has been rising in order to minimize the losses in power transmission. The high voltage electric machines should be minimized due to the constraints of space. Therefore, the temperature of high voltage electric apparatuses easily exceeds the temperature limits. In this paper, it is investigated that how to minimize the internal temperature rising of a high voltage switchgear by adjusting the arrangement of bus bars. High voltage switchgears consist of a circuit breaker, a CT, a PT, a earthing switches, bus bars, and so on. It is very difficult to estimate the electromagnetic properties of a high voltage switchgear due to these various environments and structures. In this paper, analyses are focused on the electromagnetic characteristics of bus bars according to the arrangement method and the enclosures to simplify the electromagnetic characteristics of a switchgear. It is found that the characteristics of electric field intensity and electromagnetic losses in bus bars are influenced by the arrangement method of bus bars. However, it is confirmed that the electromagnetic characteristics of enclosures are not affected by the arrangement of bus bars. In this paper, the arrangement methods of bus bars to minimize the electric field intensity and electromagnetic losses are suggested. It is expected that the research results are helpful to design and develop an electrically reliable high voltage switchgear.

Since the twentieth century, common exhibitions have experienced display replacements and apace alterations. As a result, not only the visual space background of the spectators but the structure systems and positions of the construction space have also been changed. With regards to common zones of the exhibition space, appropriate harmonization of spectators space, aisle space, and media space are closely related the effectiveness and propriety of display arrangement. A number of preceeding researches suggest exhibition first, construction next, regarding the order of the construction and exhibition of the museums and art galleries. However, a majority of the exhibition hall constructions in Korea have not been carried away based on these models. Thus, disharmony of constructions and exhibition space structures have caused numerous problems. The purpose of this research is to seek the countermeasures that can be used in the stage of planning for the museum constructions and exhibition space by suggesting, based on the above mentioned points, the development of the indicators and analyzing methods to understand the structural attributes of the common exhibition space through space syntax method and multivariate analysis.

This thesis sets out to study the immanent mechanism of architecture which had classified as external spaces in general. As human controls a space, it controls or manages human's behavior, too. This study is depended on the humanities to analyze a various operation of power in the architectural space. It makes a comparative study of a space-power in a dwelling space through a discourse of Michel Foucault and Jacques Lacan, in particular everyday's microscopic scope. According to analytical results, the space-power of dwelling falls under the influence of a spacial arrangement and subject's desire. It has shown a noticeable characteristics in aspects production & consumption, using behavior, and use value. As it is seen through the aspects of production & consumption, owns of the space-power in a dwelling could not be its subject. We have also understood about a physicalistic furniture at the using behavior, it has a special power unconsciously to control a human's action and lifestyle. And then in the aspects of use value, the centric theme is a television. It lies on the core of space-power in dwelling, because is profoundly related to an innate respect of a dwelling value. In conclusion, so this study has the important meaning in the side to offer some interpretative possibility about the architectural space-power through a microscopic structure.

In the spatial configuration of a unit plan, two rules exist: one that governs the arrangement of spaces, and one that controls the design process of generating a unit plan. This study defines space grammar as an integration of the two rules that give birth to a given spatial configuration and as the process of the generation of unit plans. To understand the distinctive features of Indonesian row houses, this study analyzes the unit plans of row houses in new towns of the metropolitan cities of Indonesia, derives a common space grammar from the unit plans, and interprets the sociocultural background that has produced this space grammar. This study employs Seo's (2007a; 2007b) graph-theoretic methodology to analyze the spatial configurations of unit plans along with a topographical approach to systematically illustrate the design process. The guest space was found as the most unique space of Indonesian houses, which cannot be found in other Southeast Asian houses. Kitchen was clearly seperated from the dining and living spaces, following traditional custom. Dining space was found to serve as a circulation center, connecting the entrance, the lving area and the kitchen. This study locates the basic orders of primary space and the design principles that dictate the unique spatial configurations of Indonesian row houses. This study reveals the basic space grammar that underpins the forms of Indonesian row houses, explaining the sociocultural and geo-climatic factors affecting this space grammar and proposing unique characteristics of Indonesian contemporary houses.

The presented study was designed to investigate the attribution of the visual perception of decorating techniques that have often been witnessed in the realm of modern fashion since 2006. The form is more impressive, more suitable to convey a message and, most of all, more memorable. In this study, attempts were made to categorize and create an order of prioritization among components such as surrounding, pattern (closure), space arrangement, area, overlapping, and community (proximity) surrounding that comprise the place and arrangement of decorating techniques in modern fashion. The results were as follow: First, centered decorating technique surrounded by other techniques is prioritized. Second, the more standardized the clothing with patterns, the more it was noticed. Third, the space arrangement also had an impact on prioritization in the following order: center of the sight, horizon, vertical, and diagonal in relation to the central axis. Fourth, concentrated area attracted more attention. Fifth, when overlapped, what is placed in the front became the center of recognition. Sixth, the technique that formed a community was more recognized. Therefore, the study suggests that as the decorating technique is gaining more significance, these findings would help to find the most effective method to utilize an acute visual stimulus to apply for a technique and maximize its aesthetic effects.

Ground penetrating radar (GPR) survey is a geophysical method that utilizes electromagnetic waves reflecting from a boundary where the electromagnetic property changes. As the frequency of the antenna is about 25 MHz ~ 1 GHz, it is effective to acquire high resolution images of underground pipe, artificial structure, underground cavity, and underground structure. In this study, we analyzed the change of signals reflected from the same underground objects according to the arrangement of transceiver antennas used in ground penetrating radar survey. The antenna used in the experiment was 200 MHz, and the survey was performed in the vertical direction across the sewer and the parallel direction along the sewer to the sewer buried under the road, respectively. A total of five antenna array methods were applied to the survey. The most used arrangement is when the transmitting and receiving antennas are all perpendicular to the survey line (PR-BD). The PR-BD arrangement is effective when the object underground is a horizontal reflector with an angle of less than 30°, such as the sewer under investigation. In this case study, it was confirmed that the transmitter and receiver antennas perpendicular to the survey line (PR-BD) are the most effective way to show the underground structure. In addition, in the case where the transmitting and receiving antennas are orthogonal to each other (XPOL), no specific reflected wave was observed in both experiments measured across or parallel to the sewer. Therefore, in the case of detecting undiscovered objects in the underground, the PR-BD array method in which the transmitting and receiving antennas are aligned in the direction perpendicular to the survey line taken as a reference and the XPOL method in which the transmitting and receiving antennas are orthogonal to each other are all used, it can be effective to apply both of the above arrangements after setting the direction to 45° and 135°.

In the preceding tests using the KSR-III Sub.(I) engines, it was observed that the heat resistant capability of the engines was not enough for the mission. So Sub.(I) Mod. engines were designed and tested. The Sub.(I) Mod. engines have three major design parameters - the arrangement of main injectors, the impinging angle of main injectors and thermal barrier coating. More than twenty experiments were carried on to evaluate engine performance and heat resistance capability with respect to design parameters. In this study, the test results are introduced. Analysing the result of Sub.(I) engine tests, it is found that decreasing the impinging angle, adopting the H-type arrangement(rather than radial type arrangement) and adopting the thermal barrier coating can increase heat resistance capacity substantially. Also, engine performance evaluation is conducted using specific impulse and characteristic velocity parameter. The results show that the performance variation is small(about 5%) and the performance is better in the case of radial arrangement. It is suspected that these phenomena are caused by the change of flame structure atomization mixing characteristic of sprays and the distortion of recirculation zone. Also from the low frequency instability point of view, it is observed that reducing the impinging angle and adopting the H type arrangement can increase the instability characteristics.

The 2-dimensional arrangement method of nodes has been used in most of RF (Radio Frequency) based communication network simulations. However, this method is not useful for the an none-obstacle 3-dimensional space networks in which the propagation delay speed in communication is very slow and, moreover, the values of performance factors such as the communication speed and the error rate change on the depth of node. Such a typical example is an underwater communication network. The 2-dimensional arrangement method is also not useful for the RF based network like some WSNs (Wireless Sensor Networks), IBSs (Intelligent Building Systems), or smart homes, in which the distance between nodes is short or some of nodes can be arranged overlapping with their different heights in similar planar location. In such cases, the 2-dimensional network simulation results are highly inaccurate and unbelievable so that they lead to user's erroneous predictions and judgments. For these reasons, in this paper, we propose a method to place uniformly and randomly communication nodes in 3-dimensional network space, making the wireless link with neighbor node possible. In this method, based on the communication rage of the node, blocks are generated to construct the 3-dimensional network and a node per one block is generated and placed within a block area. In this paper, we also introduce an algorithm based on this method and we show the performance results and evaluations on the average time in a node generation and arrangement, and the arrangement time and scatter-plotted visualization time of all nodes according to the number of them. In addition, comparison with previous studies is conducted. As a result of evaluating the performance of the algorithm, it was found that the processing time of the algorithm was proportional to the number of nodes to be created, and the average generation time of one node was between 0.238 and 0.28 us. ultimately, There is no problem even if a simulation network with a large number of nodes is created, so it can be sufficiently introduced at the time of simulation.
