As the quality of life has improved today, there is a growing desire among consumers for new space and interest in spending their valuable time in 'the third space' has tended to increase. Cafes have been integrated with sales and exhibition space as the representative third space. For example, it's cafe type automobile exhibition centers. The purpose of this study is to examine the characteristics of 'the third space' in cafe type automobile exhibition centers and suggest a plan for effective spatial characteristics. It checked the necessity of the third space' in automobile exhibition centers by analyzing automobile consumption trends of the 21st century according to industry change and restructures a checklist by grasping cafe type automobile exhibition centers and the concept and characteristics of 'the third space' based on the precedent studies. A questionnaire is made through the checklist drawn and a survey is conducted targeting users of the target areas of cases. The target areas of cases are 4 cafe type automobile exhibition centers opened in Korea since 2014. The analytical results of the target areas of cases that reflected the characteristics of 'the third space' are as follow: First, cafe type automobile exhibition centers must be built to make customers enter the space and at the same time, receive information on automobiles and space naturally. Second, in order to increase satisfaction with the space and brands, there is the necessity to arouse their interest through various experiences including test driving cars directly. Third, revisit intention can be found to be more influenced by spatial design than brand satisfaction. Fourth, partitions or interior for dividing the space need to be improved. In the next studies, specific research on plans about creating design to improve corporate image and brands and induce customers to revisit cafe type automobile exhibition centers by applying the characteristics of 'the third place' to them is required.

In this paper, we describe the first multi-frequency synthesis observations of blazar 0059+581 made with the Radioastron space-ground interferometer in conjunction with the Korean VLBI Network (KVN), Medicina and Torun ground telescopes. We conducted these observations to assess the spaceground interferometer multi-frequency mode capability for the first time.

We developed a computer program to predict solar interference period. To calculate Sun's position, we used DE406 ephemerides and Earth ellipsoid model. The Sun's position error is smaller than 10arcsec. For the verification of the calculation, we used TU media ground station on Seongsu-dong, and MBSAT geostationary communication satellite. We analysis errors, due to satellite perturbation and antenna align. The time error due to antenna align has -35 to +16 seconds at $0.1^{\circ}$, and -27 to +41 seconds at $0.25^{\circ}$. The time errors derived by satellite perturbation has 30 to 60 seconds.

The Total Electron Content (TEC) measured from Global Positioning System (GPS) can be continuously or peculiarly increased (positive ionospheric storm) or decreased (negative ionospheric storm) with solar and geomagnetic activities as well as the chemical and dynamic processes with thermosphere in the mid-latitudes. The ionospheric storm is not easy to predict owing to its difficult mechanism, and the real-time GPS TEC monitoring may be useful to follow ionospheric response to solar and geomagnetic storms. Korea Astronomy & Space Science Institute has continuously monitor GPS TEC over Korea Peninsula in near real-time of 10 minutes to watch activities. In this presentation, we will report the variation of GPS TEC over Daejeon and JeJu in Korea during the period of solar flare eruption and geomagnetic storm events in 2011. These events in 2011 will be compared with the event in October 2003 and November 2004.

The hydraulic acoustic attenuator fur an automotive active suspension system is so highly nonlinear and of high order that the analysis in time-domain has been performed quite little. In this paper, a state-space representation of the dynamics for a hydraulic attenuator was presented utilizing the electrical analogy. And the results of experiment were compared with those of simulation to validate the state-space model proposed. The comparison revealed that the state-space model proposed is practically applicable to estimate the dynamic responses of the hydraulic attenuator in time-domain.

The most work-space invest much time and labor for optimal arrangement. The work-plates of the work-space should be arranged, processed and assembled under the restricted work space. The optimal arrangement under the terms of a restriction arrange the maximum work-plates in appointed work-space. It's the central aim. The work-plates arrangement scheduling of the most work-space are achieved through the experience of the planner. Like this, if the work-plates arrangement is worked by hand, there spend much time for the training planner. And the burden of the personnel expenses occur for using the master worker, also there are dangerous factors to be able to bring the bottleneck circumstance for the process planning, because the quick work planning does not accomplish. With such problems, the biggest problem is inferior the value of the plan. For solved the such problem of hand-operating, some work-spaces developed and used the work-plate arrangement scheduling system for the special quality of themselves. This paper make research into a plan to develop the work-plate arrangement scheduling system efficiently.

Media company is not a business which sells news and information but a company sells audience's attention. Advertisers estimate audience's quantity and quality which pay attention to media and pay the cost. Thus drawing audience's attention is a natural and instinctive behavior for survival of media company. News doesn't deliver the fact just as it. That's impossible. News is a commodity made by processing and selection of the media company and journalist. On the process, judge of values is involved and limitation of time and place of media is considered. If scientists understand media's character truly, their misunderstanding about media company and journalist may be cleared up. In this society, media is not a being to ignore, particularly for big science like space science which spends huge public capital. Nowadays, space science meets the time to take the leap in Korea. However that can be crisis cause of uncertainty of science activity. When the crisis which no one desires happens, preparation needs for new opportunity. We can take the crisis as a chance. Understanding about media and public will be the first step for this preparation.

This paper proposes a new method of reducing the processing time and the size of consummimg memories in Hough transform. In this method, only the functional patterns are considered. The candidate points which are accumulated into the parameter space are computed in a many-to-one fashion and the parameter space is quantized dynamically to maintain a fine precision where it is needed. And a coarse-to-fine extraction method is used to reduce the processing time. The many-to-one fashional computation results in a relatively high-densed accumulation of candidate points around the parameter points corresponding to the image patterns in the image space. So, the dynamic quantization procedure can be simplified and the local maxima can be determined easily. And more effective reduction can be obtained as the dimension of parameter space is increased.

Adjunctive orthodontic therapy may be required to create appropriate space, to address misalignment and tooth size discrepancy for better function and esthetics. The desired interproximal alveolar contour and gingival embrasure form can be developed during treatment. Various applications of temporary anchorage devices for pre-prosthetic tooth movement allowed clinicians to achieve high efficiency, shorter treatment time, and less discomfort of patient. Biomechanical considerations for the periodontal status of the affected teeth are required to successfully control the vertical and horizontal space. Hence, the interdisciplinary approaches have an essential role in maximizing the favorable treatment outcome. In particular, pivotal Clinical decisions such as whether to open or close the space should be made by consensus of the involved dentists. This article presents the orthodontic treatment approaches for prosthodontic works including mesiodistal and vertical space regaining specially for cases of unrestored teeth over an extended period of time.
