Open education has been established for 10 years in Korea. In spite of relatively long history of open education, there are only two schools which have well structured open space to support open education. Development of open curriculm and open space is a vital elements for the success of open education. This study aims at introducing the concept and development of open space and analyze the role of media center to improve open education. Especially emphasis is placed on how the open space should be organized for the effective open education. The open space should include 4 areas such as instructional area, production area, storage area and teachers' area. There are, however, no standardized format for the open space and education. Open space should be flexibly restructured to adapt to rapidly changing educational environment.

Based upon the previous heritage in the complete development of the infrared imaging spectrometer, NISS (Near-infrared Imaging Spectrometer for Star formation history) onboard NEXTSat-1, we are participating in the NASA MIDEX mission (PI Institute: Caltech), the all-sky infrared spectro-photometric surveyor SPHEREx (Spectro-Photometer for the History of the Universe, Epoch of Reionization, and Ices Explorer). The SPHEREx will provide us the first all-sky infrared spectro-photometric data set to probe the origin of our Universe, to explore the origin and evolution of galaxies, and to explore whether planets around other stars could harbor life. After the SPEHREx have passed the PDR (Preliminary Design Review) on this September, the fabrication of flight hardware will be started soon. As an international partner, KASI takes part in the hardware development, the operation and the science for the SPHEREx. Here, we report the status of the SPHEREx project and the progress in the Korean participation.

Technological development of information and communication have brought sharp changes to every sector such as society, culture, economy and education because of knowledge and information-oriented society. The number of classes has decreased, and some schools are closed or incorporated due to decrease of the population. Such phenomenon has brought changes to learning using digital technology and space. A change called digital innovation is characterized by interactive communication centering on the internet network. Therefore, it is very important to predict educational environment to be changed according to digital environment and to note how real learning space is changed. The development of digital technology in society in general presents two concepts of digital and contents, digitalized information. Such technology is recognized as a new paradigm in education sector and a new space is created through participation of instructors and learners in learning space. This study analysed cases of learning space of elementary schools based on bibliographical examination and related bibliography including data from academic presentations and news release to present developed leaning space. To present healthy and creative learning environment which can lead knowledge and information-based society in the future, the preface described the background, purpose, methods and range of the study, and analysed transitional processes of society and culture, digital learning contents, and learning space in education of elementary schools. Finally the study identified trends and cases of research on learning space and suggested digital learning contents space.

Purpose - The purpose of this study was to analyze the impact of the National Space Policy on Korean space-related companies. Design/methodology/approach - This study utilized space sector firm-level data based on the list of the Space Industry Survey (MSIT, 2023). The multiple regression analysis was used to estimate the model. Findings - First, the lagged policy variable of the Master Plan for Promotion of Space Development positively influences the company's sales. However, the establishment of an Action Plan for Utilization of Satellite Information had no significant result. Second, small-sized enterprises were more sensitive to government policy than medium- and large-sized enterprises. Third, lagged policy variables positively impact firms' sales revenue, especially in the satellite manufacturing and the satellite utilization services and equipment sector. Research implications or Originality - First, support for companies with policy effects should be further expanded. Second, a long-term and stable budget procurement plan should be established to secure a firm's sustainable competitiveness. Lastly, given the characteristics of the space industry, which involves long-term development periods and large investments, government investment should continue. Simultaneously, institutional improvement needs to emerge new services in the space sector.

Mobile communications is argued to reshape and activate the existing space by increasing 'mobile communicability en route' and 'real time interaction.' This study is designed to make an empirical analysis on how different the use of a cellular phone is in each different space. In this study, the space is divided into three distinct parts including the private, social and public space. First, spatial micro-coordination and experience of polysemy of place are widely observed in the use of a mobile phone in the private space. Secondly, it is found that a mobile phone contributes to extending the scope of social contacts which in turn compliments the existing social relationship. Moreover, a full-time intimate community that is connected via a mobile phone results in reshaping the social space. Lastly, the study shows that the usage pattern of a mobile phone varies depending on the type of public space. The technological development is envisaged to lead to more demand for the public space while facilitating the use of the public space.

There would be a long-waited launch of a Korean space launch vehicle(KSLV-I) in NARO Space Center which is located in Goheung, Jeol La Nam Do in Korea. Korea would be the nineth country in the world which could launch space launch vehicle itself. The launch of the 2nd technology satellite of 100kg with KSLV-I would give Korean hope and dream. In addition to the traditional space activities of U.S.A. and Russia, Japan launched the lunar satellite, Kaguya in 2007, China launched the lunar satellite, Change and succeeded in space walk and India launched the lunar satellite Chandrayaan in October, 2008. In this paper we study on the trend of domestic and international development of space launch vehicle considering all these space development activities.

This paper discusses recent development trends of fiber optic gyroscope (FOG) in space application. Fiber optic gyroscope utilizes Sagnac effect to measure the angular rate of a rotating object in space. Having a rather short development history compared to ring laser gyroscope (RLG), the fiber optic gyroscope, owing to the emerging technologies in fiber optic society and the digital signal processing technique, reveals itself as a noteworthy replacement of the ring laser gyroscope in the space mission. This paper summarizes the current trends of fiber optic gyroscope based on the actual products commercialized in the market over the last decades, while presenting the future development trends of the fiber optic gyroscope in the space exploration.

This research intends to make a model of space development in Korea as a sectoral innovation system. The main contents include a character analysis of the elements of three low levels of the space development innovation system, including governance (the main agent and cooperation relationship of which the center is a research institute supported by government), resources (financial resources and human resources), and the diffusion of research results. It is important to grasp the factors that bring about technological innovation of industrial sectors to produce technological innovation policy. Technology innovation policy should thus be formulated for specific, individual sectors, and not all sectors.

This paper introduces the upper stage attitude control system of KSLV-I, which is the first space launch vehicle in Korea. The KSLV-I upper stage attitude control system consists of two electro-hydraulic actuators and a reaction control system using cold nitrogen gas. A proportional, derivative, and integral controller is designed for the electro-hydraulic thrust vectoring system, and Schmidt trigger ON/OFF controllers are designed for the reaction control system. Each attitude controller is designed to have enough stability margins. The stability and performance of KSLV-I upper stage attitude control system is verified via hardware in the loop tests. Hardware in the loop tests are accomplished for perturbed flight conditions as well as nominal flight condition. The test results show that the attitude control loop of KSLV-I upper stage is very stable and the attitude controllers perform well for all flight conditions. Attitude controllers designed in this paper have been successfully applied to the first flight of KSLV-I on August 25, 2009. The flight test results show that all attitude controllers of the KSLV-I upper stage performed well and satisfied the accuracy specifications even during abnormal flight conditions.
