본 논문은 인간의 다양한 활동이 펼쳐지고 있는 공간과 장소의 특징에 따른 유기적 관계의 현상을 살펴보는데 목적을 갖고 있다. 그에 따른 인간의 다양한 경험의 확산과 상호구축망을 형성하는 공간과 장소의 상호작용은 개인 또는 집단적 경험의 확장성을 마련하는 계기를 조성한다. 인간 활동의 상호작용을 이끌어내는 공간과 장소는 다양하게 표출되고 있다. 특히, 국내 여행프로그램을 통해서 공간과 장소의 표현방식은 다양한 '경험의 장'으로 확산되고 있는 추세이다. 그에 따른 여행프로그램의 구성과 표현방식은 기존의 기행적 스타일을 벗어나 생각하고, 사고할 수 있는 '체험의 장' 문화의 형성을 통해 공간과 장소가 단순한 경험이 아닌 사유의 대상으로 변모되고 있다. 그러므로 본 연구에서는 MBC 플러스 채널의 <어서와 한국은 처음이지?> 여행 프로그램을 통해서 표출되고 있는 공간과 장소성이 갖고 있는 체험을 통해서 표출되는 사회문화적 관점에서의 특징을 살펴보았다. 본 연구의 스토리 전개구성 분석결과는 공간과 장소의 체험은 음식과 커뮤니케이션의 삼중적 관계에 따른 다양한 문화적 할인의 경계가 최소화되는 것으로 나타났다. 또한 미이어 소통 구조의 분석결과는 주체와 대상간의 공감상황, 공감주체, 공감도구, 공감내용을 통해서 리얼리티의 효과를 극대화하고, 문화적 차이와 경계의 간극을 최소화하는 과정을 통해서 수용자의 감성코드를 전달하는 것으로 분석된다.

Sudden enhancements of daytime NmF2 appeared in Anyang ionosonde data during summer seasons in 2006-2007. In order to investigate the causes of this unusual enhancement, we compared Anyang NmF2's with the total electron contents (GPS TECs) observed at Daejeon, and also with ionosonde data at at mid-latitude stations. First, we found no similar increase in Daejeon GPS TEC when the sudden enhancements of Anyang NmF2 occurred. Second, we investigated NmF2's observed at other ionosonde stations that use the same ionosonde model and auto-scaling program as the Anyang ionosonde. We found similar enhancements of NmF2 at these ionosonde stations. Moreover, the analysis of ionograms from Athens and Rome showed that there were sporadic-E layers with high electron density during the enhancements in NmF2. The auto-scaling program (ARTIST 4.5) used seems to recognize sporadic-E layer echoes as a F2 layer trace, resulting in the erroneous critical frequency of F2 layer (foF2). Other versions of the ARTIST scaling program also seem to produce similar erroneous results. Therefore we conclude that the sudden enhancements of NmF2 in Anyang data were due to the misrecognition of sporadic-E echoes as a F-layer by the auto-scaling program. We also noticed that although the scaling program flagged confidence level (C-level) of an ionogram as uncertain when a sporadic-E layer occurs, it still automatically computed erroneous foF2's. Therefore one should check the confidence level before using long term ionosonde data that were produced by an auto-scaling program.

On August 17th 2017, for the first time in the history, the gravitational wave (GW) detectors recorded signals coming from the merger of two neutron stars. This event was named as GW170817, and more interestingly, gamma-ray emission was detected 2 seconds after the gravitational wave signal, and 11 hours later, telescopes in Chile identified that the GW signal came from the NGC 4993 galaxy at the distance of about 40 Mpc. This is again the first time that electromagnetic (EM) signals are detected for a GW source. The follow-up observations by astronomers all around the world, including our group in Korea, successfully identified the optical emission as the kilonova, the elusive optical/NIR counterpart that has been proposed to originate from a neutron star merger. This whole event started the new era of astronomy, so-called the "multi-messenger astronomy", where the combined information from GW and EM radiation reveals an unprecedented view of the universe. In this talk, I summarize this exciting event, and describe the efforts by Korean astronomers that have led to important discoveries about the kilonova and the host galaxy properties, and finally provide the future prospects.

Recently, the public offices are going to be an important role of CIP(City Identity Program) and be a center of citizen's community activities. So, the aspect of the universal design (UD), the space performance assessment for a disable user is invaluable to designing the public office spaces. Purpose of this paper is to provide basic data for better design of public office space based on UD(universal design) principle. Conclusion based on the finding are as follows; First, checklist of environmental assessment for public space was composed of 7 basic principles of UD and 3 additional principles(aesthetic appreciation, maintenance and eco-design). Second, as the result of assessment, accessible and inclusive design is more necessary. Third, local characteristics should be developed and managed deliberately as to public space design. As the result of that, public office space design should an important part of reducing the isolation that was caused by physical and social disability. From now on, in public office space design, the integrated and continuous design program that is based on UD principle and eco-design will be necessary.

Aalto designed his own modern architecture in comparison with other modern architects of his days. It is because Aalto went beyond the principle of dogmatic functionalism based on his attitude not to copy images of functionalism but to fulfill function of the building. He decided architectural form and space according to logical basis including the effective use of light and sound. Vuoksenniska church, as is called the most exceptional and notable church in his works, was designed based on the fulfillment of program. As he knew that the program needed the extension of the main church space into social areas, he put emphasis on individuality of space rather than the wholeness of space. Sound and light analysis of Vuoksenniska church shows that Aalto tried to have adequate environment of each space at the start and Integrate them later. The spatial configuration of Vuoksenniska church shows that the individuality of space has priority over the wholeness of spaces. Discordance between roof form and ceiling is the best example for this matter. Aalto designed various windows that have different sizes, figure and location to induce desirable light for each space of the church. He also adjusted the shape of the ceiling and the angle of wall for a effective sound transmission. This result indicates that he knew the activity of the church is normally confined to one weekly morning and the whole space Is hardly used as a religious purpose.

2010년에 발사될 예정인 아리랑위성 5호의 부 탑재체인 AOPOD(Atmosphere Occultation and Precision Orbit Determination) 시스템은 GPS(Global Positioning System) 전파 엄폐(radio occultation) 자료를 제공한다. 이 논문에서는 아리랑위성 5호 궤도에서 발생하는 GPS 전파 엄폐의 발생 빈도 및 분포를 시뮬레이션하고, 현재 천문연구원에서 개발 중인 GPS 전파 엄폐 자료처리시스템인 KROPS(KASI Radio Occultation Processing System)를 사용한 전리층 전자밀도 산출결과를 제시하였다. 전자밀도를 산출하기 위해 2004년 6월 20일에 발생한 CHAMP(CHAllenging Minisatellite Payload) 위성의 GPS 전파 엄폐 관측값을 사용하였고 산출된 결과는 IRI(International Reference Ionosphere) - 2001 모델과 CHAMP 위성의 랑뮈어 탐침기(Planar Langmuir Probe) 및 이온존데 간과 비교하였다. 산출된 전자밀도를 이온존데 값과 비교했을 때, $F_2$층 최대전자밀도 고도인 $hmF_2$에서 약 5km, $F_2$층 최대전자밀도인 $NmF_2$에서 약 $3{\times}10^{10}el/m^3$의 차이를 보였으며, 랑뮈어 탐침기 값과 비교하여 고도 365.6km에서 두 값 모두 $1.6{\times}10^{11}el/m^3$로 일치하였다.

This study focuses on the proposal of the basic data for the design guideline on the coming design, through the comparison analysis of the community facility's layout type inside housing complex, the space configuration and the characteristic of space program for the achievement and improvement of the physical space to cultivate the sense of community. This study investigate interviews with designers, administrators, residents, and site survey. The result of study shows that the community facilities in the public rental apartments have changed to include various programs and to increase the area like the public sales apartments, but there are spacial transformation if the community facilities do not apply the residents characteristic.

The utilization of underground space has recently increased with the complication of road, the rise of the land price, and the development of green technology. Underground space ranges from classical excavations to subway, underground cities, and shopping malls where there are crowds of people. At this time, government has spent a lot of money in installing various types of safety facilities for preparations of increasing potential disasters. Therefore, an effective facility management system is required. In this paper, we propose an information retrieval process to effectively extract the facilities' information based on the ontology and spatial analysis in underground space. The ontology-based searching supports hierarchical and associated results as well as knowledge sharing with hierarchy concepts. The spatial analysis based searching has "Buffer" and "Near" functions to operate on a map without understanding any property of the facility information.
