Satellite optical communication has gained significant attention owing to its many quality features (e.g., a larger bandwidth, license free spectrum, higher data rate, and better security) compared to satellite microwave communication. Various experiments have been performed during many space missions to demonstrate and characterize inter-satellite links, downlinks, and uplinks. Korea has also planned to establish an experimental communication system using a geostationary earth orbit (GEO) satellite and the Geochang station as an optical ground station for low Earth orbit (LEO)-to-ground optical relay links. In this study, the performance of inter-satellite communication links and downlinks was investigated for the new Korean experimental communication system in terms of link margin, bit error rate (BER), and channel capacity. In particular, the performance of the inter-satellite links was analyzed based on the receiving apertures and the transmitting power, while that of the downlink was analyzed in terms of atmospheric turbulence conditions and transmitting power. Finally, we discussed two system parameters of receiving aperture and transmitting power to meet the three criteria of link margin, BER, and channel capacity.

Laser communication has been considered as a novel method for earth observation satellites with generation of high data volume. It offers faster data transmission speeds compared to conventional radio frequency (RF) communication due to the short wavelength and narrow beam divergence. However, laser beams are refracted due to atmospheric turbulence between the ground and the satellite. Refracted laser beams, upon reaching the receiver, result in angle-of-arrival (AoA) fluctuation, inducing image dancing and wavefront distortion. These phenomena hinder signal acquisition and lead to signal loss in the course of laser communication. So, precise alignment between the transmitter and receiver is essential to guarantee effective and reliable laser communication, which is achieved by pointing, acquisition, and tracking (PAT) system. In this study, we simulate the effectiveness of tip/tilt compensation for more efficient laser communication in the satellite-ground downlink. By compensating for low-order terms using tip/tilt mirror, we verify the alleviation of AoA fluctuations under both weak and strong atmospheric turbulence conditions. And the performance of tip/tilt correction is analyzed in terms of the AoA fluctuation and collected power on the detector.

Exhibit space is result that various kinds works of architecture design, interior design, plan and control of exhibit program, embodiment to display space, operation and administration etc. are formed accomplishing creation. Because exhibit space must consider interaction of value that is in dwelled along with the external form about human and exhibits. Therefore, display space of exhibition must achieve functional role that can accomplish communication with spectator as well as function as place that possess products of accumulative value. Therefore, we must establish effective communication plan by position and form of display space as well as properly of exhibits, display contents, exhibit program to achieve purpose of trade fair display. Display space of trade fair can be classed by wall style, corner style, head style, island style, two entrance style 5 according to the position. And we must plan communication plan by these position dividing the function to passive communication area, active communication area, intensive communication area, function achievement area. We will can grope contents and method for successful exhibit through communication plan that is connected form and position of exhibit between exhibit space of such trade fair and we may achieve purpose of trade fair display.

Language is the method for communication. Semantician, G. Leech categorized the function of language as informational, expressive, directive, aesthetic and phatic one. Therefore, language can be defined as the social symbol system and the media for communication. Space, also, performs the role of symbol, information and communication. Space can be the media for the communication and the design can be logical construction process by it's arbitrary interpretation. The researcher considered the common points between verbal language and visual language as the tools for the mutual communication, tried to transit them into the 'space' as object language after analyzing 'image of poetry' as meta language, so that the old perspective of space design as function can be renewed as information system of the significant meaning delivery in the context of language's multiplicity, expandibility and changeability.

The small-scale magnetospheric and ionospheric plasma experiment (SNIPE) is a mission initiated by the Korea Astronomy and Space Science Institute (KASI) in 2017 and comprises four 6U-sized nano-satellites (Korea Astronomy and Space Science Institute Satellite-1, KASISat-1) flying in formations. The main goal of the SNIPE mission is to investigate the space environment in low Earth orbit at 500-km. Because Iridium & GPS Board (IGB) is installed on the KASISat-1, a communication simulation is required to analyze the contact number and the duration. In this study, communication simulations between the Iridium satellite network and KASISat-1 are performed using STK Pro (System Tool Kit Pro Ver 11.2) from the AGI (Analytical Graphics, Inc.). The contact number and durations were analyzed by each orbit and date. The analysis shows that the average access number per day is 38.714 times, with an average of 2.533 times per orbit for a week. Furthermore, on average, the Iridium satellite communication is linked for 70.597 min daily. Moreover, 4.625 min is the average duration of an individual orbit.

This study, as primary research that examines the communication characteristics of the library and the perception of librarians in order to make public libraries a communication space, surveyed the perception of librarians in public libraries and made an attempt to devise activation measures for the communication spaces of the library. As a result, the communication characteristics of the library were derived to be locality, community spirit, and interactivity. In addition, the perception survey found that librarians have positive remarks about the communication spaces of the library. As it shows a high degree of awareness, the library should focus on ways to revitalize communication. First, the direction of communication must be set in order to fulfill library's new role in communication and exchange. Second, it is desirable for the library to free itself from being a quiet space and recreate it as a space for communication. Third, the library needs to exchange and connect with organizations, groups, and gatherings of the community. Fourth, it seems necessary for the library to provide support for the users' independent and voluntary communication and operation of the community.

Scientific CubeSat with Instruments for Global Magnetic Fields and Radiations (SIGMA) is a 3-U size CubeSat that will be operated in low earth orbit (LEO). The SIGMA communication system uses a very high frequency (VHF) band for uplink and an ultra high frequency (UHF) band for downlink. Both frequencies belong to an amateur band. The ground station that communicates with SIGMA is located at Kyung Hee Astronomical Observatory (KHAO). For reliable communication, we carried out a laboratory (LAB) test and far-field tests between the CubeSat and a ground station. In the field test, we considered test parameters such as attenuation, antenna deployment, CubeSat body attitude, and Doppler frequency shift in transmitting commands and receiving data. In this paper, we present a communication performance test of SIGMA, a link budget analysis, and a field test process. We also compare the link budget with the field test results of transmitting commands and receiving data.

Space is a phenomenon which is formed in the connection between environment and human beings and public space is built by a complex phenomenon of space. Each and every individual is connected to an environment and these individuals are connected to one another. A public commemorative space means souvenir and memorial which is designed for special purpose of remembrance of a specific area. One of the purposes of public commemorative space is memorial and that is the reason of doing public relation and educating citizens over the transom. However, the meaning and value of commemorative subject cannot be delivered or stuffed one-sidely. The target who receives messages from public commemorative space has reinterpreted the messages of his own with his personal experience, knowledge and sensitivity. It results in an unexpected phenomenon of public commemorative space. Therefore, public commemorative space should be considered in a mutual communication structure rather than a purpose of memorial itself. Korean public commemorative space is focused on public relation and education for memorial. In other words, Korean public commemorative space is neglected its important possibility of the productive chapter of mutual communication. The mutual communication structure of public commemorative space which is based on variety and haecceity is ripped up by the message over the transom. It destroys the self-control and creativity of public commemorative space, and derives a negative result. By studying the function and meaning of public commemorative space, we should make the best use of it.
