In this paper, we introduce the performance evaluation and development of Raw VLBI Data Buffer(RVDB) system for the synchronized playback processing of observed data in Korea-Japan Joint VLBI Correlator(KJJVC). The high-speed correlation processing system is under development so that the radio data obtained with 8192 channels and 8 Gbps speed from 16 stations will be able to be processed. When the recorded data of each station are played to correlator, the time synchronization of each station is very important because the correlator should process the data obtained with same time and condition. There are many types of recorder systems in the East Asia VLBI Network (EAVN). Therefore it is required to prepare the special time synchronized playback processing system to synchronize the time tag of observed data. The developed RVDB system consists of Data Input Output(DIO), 10GbE switch, and Disk Data Buffer(DDB). It can record the data with maximum 2 Gbps speed, and can play back the data to correlator with nominal 2 Gbps speed. To enable to play back the data of different playback system to the correlator, we developed the high-speed time synchronized playback processing system. We carried out the experiments of playing back and correlation for gigabit correlator and VCS trial product so as to confirm the performance of developed time synchronized playback processing system. In case of online and offline playing back experiment for gigabit correlator, we confirmed that the online and offline correlation results were the same. In case of playing back experiment for VCS trial product, we verified that the wide band and narrow band correlation results were also the same. Through the playing back experiments of RVDB system, the effectiveness of developed RVDB system was verified. In this paper, the system design, construction and experimental results are shown briefly.

This study has examined layout of communal outdoor space and welfare facilities in the nation's very first senior apartment complex in Segok-dong, Gangnam-gu that has been developed by Seoul City. In order for this space to play a role as a center of communication: 1) A center space of community should be created at the point of intersection of main moving lines of pedestrians. 2) Hierarchical area should be set up between main moving lines of walking and communal outdoor space. 3) It should be designed in a way to reflect demands of seniors and be accommodated their activities and behaviors. 4) It should be functionally connected to local infrastructure facilities so that it can promote social exchanges among seniors. Points to be considered in welfare facilities: 1) They should be placed at the center of the complex to provide convenience to all seniors. 2) Area of senior citizen center should be subject to flexible legal regulation in light of the unique characteristics of the Complex. 3) in case that welfare facilities are installed in the same space, intermediate space is required to alleviate collision between private space and public space. 4) Senior assistance facilities should put more emphasis on running programs that make good use of the space than on securing the space itself.

This paper explores the concept of mobile gaming platforms and changes in game play through mobile parameters, focusing on the role of role-playing mobile games through mobile parameters. As a move, the Player combines the mobile media with the game platform. The daily time of the mobile mid-dividualization is reconstructed with the principle of superposition, which affects play experience on the mobile gaming platform. The character of a mobile role-playing game plays a non-integrated play where the player is staying, rather than an avatar character, and exhibits a non-dwelling character as a residential space. Automatic battle also regenerates unused combat forces in the form of explicit integration. The experience of combat in overlapping hours serves as a visual spectacle, and the player inhabits the fighter jets.

An architecture is a result from representation of design knowledge by architect's creative thinking, and operated only in his internal organization system. Design knowledge based upon the experience that they have achieved in the past as well as the informations they have accumulated over the time. In this point of view, the Schema that formed by problems settlement and process repetitions for the best conclusion, not only play an important part in the designer's thinking system about a specific problem but also appeared by distinctive features. This research looks to achieve a new design method by finding out how architects express traditionality in the contemporary house through schema. This research analyze contemporary house built in seoul of 1990's. The result are as followings. First, Schema is a 'frame' that already exist in the architect's thinking, will make a good guide about express the traditionality. Second, We found out several distinctive characters in the form and the space. The form is divided in five types. It is an condensed form of roof image, the metamorphosis of form grammar, the change of part details, the representation of design principle and the directly expression. Lastly, In the space, it is the borrow of the connection method of inside and external space, the three parts composition of the space, the adaptation of 'Madang' and the Independent composition of the space due to 'Chae'

It suggests a closet design for infants in consideration of space utilization, furniture arrangement, and goods storage by integrating a baby's closet and toy chest, which was used for storage of baby's toys and play instrument. For this, it conducted and analyzed data research on the infants' toy chests in the domestic and overseas market and based on such approach, the colors that helped development of infants' cognition and emotion were selected while suggesting familiar animal characters for infants. Without considering separate arrangement of furniture and toy chest within limited space, it allowed space utilization and provided enough storing space. Also, the attached ball casters enabled easy carry of the closet and with this function, it helps infants arrange and store goods by themselves so that making them feel a sense of accomplishment. For effective spatial utilization as well as security of its genuine storage function, the closet and toy chest were combined in this study. Thus, it is believed that development of such multifunctional furniture will suggest the direction of researches on domestic furniture development that are conducted to maximize utilization of residential space for the people living today.

A fundamental problem in space physics is to explain the origin of energetic charged particles in space close to the Earth and the significant temporal variations of their flux. The particles are primarily electrons and protons although energetic heavy ions such as O+ are sometimes non-negligible. By "energetic" we mean a rather broad energy range of particles from a few tens of keV to well above MeV. Drastic variations of the particle fluxes (by >3 orders of magnitude) occur over both a short time scale like a few minutes and a long time scale like the 11-year sunspot cycle. In this talk I will focus on relativistic energy electrons (~MeV) trapped within the Earth's magnetosphere. They are a primary element of the space weather since they can cause damage to satellites, so often called "killer electrons". Considering that the source particles in both the solar wind and the ionosphere are relatively cold (~eV), the quasi-permanent existence of these very energetic particles close to the Earth has been a surprise to space physicists for decades. Complex electromagnetic processes such as wave-particle interactions within the magnetosphere are believed to play a major role in generating these killer electrons. While detailed physics remains an active research area, for this lecture I will introduce a synthesized picture of how solar activities are related to wave-particle interaction physics inside the magnetosphere. This can be applied to other astrophysical systems.

Character and illuminance distribution of daylighting is very important for the architectural plan in museum. Those data show bases for exhibition space design with daylighting and play a decisive role in visual perception of articles and space aesthetic. The goal of this paper was therefore to analyze the illuminance distribution in fine art museum with 3 typical girdle skylight types which are devided according to the art of protection from glare. This Experiment proved that they had a striking contrast with regard to the ratio of daylight illumination and illuminance distribution in spite of the same purpose of those development. The girdle skylight with a translucent glass showed the strongest value of the ratio of daylight illumination, but inequable illuminance distribution in space, excepting the area of the wall. However, the latticed reflector of light refracted daylight in the direction of wall and made illuminance distribution very equable in whole space. The ratio of daylight illumination at the girdle skylight which was located at the verge of the ceiling, was highest at the upper part of the wall and was reduced gradually from there, by way of the middle and under part of the wall, to the center of space.

The Main-belt asteroid (298) Baptistina (hereafter 'Baptistina') is regarded as an X- (or C-) type asteroid and the largest member of the Baptistina asteroid family. Its basic physical properties play an important role in understanding the rotational evolution and orbital dynamics of the Baptistina family. In this study, we determined the physical characteristics of Baptistina from the optical observations. We conducted BVRI and R band photometric observations from 2017 to 2021 for a total of 47 nights using the 0.5 - 2.0 m-class telescopes. As a result, the color indices of Baptistina were derived as, , and ; this result is consistent with the previous classification of Baptistina as an X- (or C-) type. We also determined absolute magnitude () and slope parameter () by using a simplified version of the IAU H & G function (Bowell et al. 1989) are mag and respectively. We calculated the effective radius of Baptistina of km considering the visual geometric albedo of 0.131 from the NEOWISE data. Using the light-curve inversion method, the sidereal rotation period of 16.224235 h and the 3D shape model with a pole orientation (,) were also determined. In this presentation we will introduce our observations and results, and also discuss about the physical properties of Baptistina asteroid family members such as color indices.
