It is a trend to pursue the reinforcement of child-centered, play-oriented ecological education programs that support children's development. Most of these nature friendly and eco education is done in the outdoor space. So outdoor activities in child care facilities are essential. The purpose of this study was to analyze the actual condition of the outdoor space for ecological child education in the child care center. Therefore, in order to provide the basic data for the direction of the improvement and to grasp the current situation and problems, the survey and analysis of the external space composition and utilization status in the child care facilities for nature-friendly ecological child care education has been done. As a result, the half of the cases did not reserve even the minimum size of outdoor space and fall short of the standards of outdoor space quality as accessibility, complexity, articulation and nature friendliness for ecological education. Therefore, in order to establish an ecological education environment, it is necessary to build facilities in natural green or suburban areas. In addition, they need to use the natural environment such as parks, open spaces, and forests.

This paper presents an analysis of the trans-lunar trajectory insertion performance of the Korea Pathfinder Lunar Orbiter (KPLO), the first lunar exploration spacecraft of the Republic of Korea. The successful launch conducted on August 4, 2022 (UTC), utilized the SpaceX Falcon 9 rocket from Cape Canaveral Space Force Station. The trans-lunar trajectory insertion performance plays a crucial role in ensuring the overall mission success by directly influencing the spacecraft's onboard fuel consumption. Following separation from the launch vehicle (LV), a comprehensive analysis of the trajectory insertion performance was performed by the KPLO flight dynamics (FD) team. Both orbit parameter message (OPM) and orbit determination (OD) solutions were employed using deep space network (DSN) tracking measurements. As a result, the KPLO was accurately inserted into the ballistic lunar transfer (BLT) trajectory, satisfying all separation requirements at the target interface point (TIP), including launch injection energy per unit mass (C3), right ascension of the injection orbit apoapsis vector (RAV), and declination of the injection orbit apoapsis vector (DAV). The precise BLT trajectory insertion facilitated the smoother operation of the KPLO's remainder mission phase and enabled the utilization of reserved fuel, consequently significantly enhancing the possibilities of an extended mission.

This study examined the integration value of a low level pilotis space, a component that has been often selected as an essential planning element of the recent high-rise apartment complex, and compared the main outdoor unit spaces with that of an average integration value of the individual complexes. Furthermore, this study provided the preliminary data for the next level of research, which is the observation of the pilotis space usage behaviors and the frequency of utilization. The results of this present research are as follows. First, from the main outdoor unit spaces of the high-rise apartment complexes including the pilotis space, a 'complex entrance' or a 'plaza' space showed the highest integration value. Second, the spatial integration value of a pilotis space in a high-rise apartment complex was generally lower that of the integration value of other main outdoor units. Third, from the pilotis spaces of the high-rise apartment complex, those with a 'projecting entry access + pilotis addition type' that did not provide an access to the individual units, had the lowest space utilization rate by the inhabitants; thus, had a high likelihood of the spaces becoming used for illegitimate activities or becoming vacant.

Purpose: The purpose of this study is to examine academic stress, social support and learning management system(LMS) utilization satisfaction of learners attending online graduate schools and understand the factors influencing their academic persistence. Methods: The participants were students of K online graduate school and the data of 143 students, in total, were collected from April to May in 2019. For data analysis, frequency analysis, x² test, t-test, F-test, Pearson's correlation and multiple regression analysis were conducted using SPSS ver. 23. Results: Academic stress, social support, and LMS utilization satisfaction were associated with academic persistence of online graduate students. The multiple regression analysis of the factors influencing academic persistence showed that the model was significant (p<.001) with an explanatory power of 23% and that significant factors influencing it were academic stress (β=-.23, p=.002), LMS utilization satisfaction (β=.31, p<.001) and jobs (β=.23, p=.002). Conclusion: Although the online graduate students' level of academic persistence was high, it is required to develop strategies to alleviate their academic stress and increase LMS utilization rate in order to increase their persistence to academic success. In addition, it is necessary to provide the foundation on which the utilization of major knowledge regarding jobs can be enhanced, reflecting the characteristics of online graduate students. Furthermore, this study is expected to contribute to the extension of professional and advanced education in response to social needs by developing a variety of online high education learning systems beyond time and space.

This paper examines current developing status of space law as defined in terms of its unique principle that "the utilization of outer space for all mankind's interest". As commercialization of space activities has brought about heated debate on its legitimacy with respect to that principle, space law has come to witness a dual situation. One is the realization of that principle in establishing commercial space activities system where all mankind's interest is respected through the non-discriminatory distribution mode of space benefit. In satellite telecommunication system, the INTELSAT Organization assures its public service policy while protecting itself against a competition from separate systems. For remote sensing, commercialization of LANDSAT Systems promoted since 1984 seems not to affect present non-discriminatory distribution of data and information obtained. On the other hand, active participation of private entity aiming at commercial profit enables national government to manage more effective control and supervision of those activities with a view to promoting national interests. Also, newly developed private rules and regulations are emerging in business relations about commercial space activities. Extended capacity of national government assuring its national interest in production and distribution of international resources that is outer space, and regulation of space activities by newly developed rules and customs provoke a concern about a identity problem of space law. The best way to summarize this perspective might consist in saying that non space law regulations, which are not assumed as aiming at the promotion of all mankind's interest, are confirming their role about space related activities. For those reasous, we are now facing a developing status of space law as developments of commercial space activities continues.

It is necessary to arrange and analyze the collected research date to get regularity such as characteristics, merits and demerits, and possibility in city when constructing land information by analyzing linkage and utilization of cadastral information as the fundamental data for land information around the acreage of a lot and by expressing the purpose of each digital data construction with map. In short, that is the work to classify data, to make chart or map, or to analyze using statistical technique. Some information in land utilization had been used by computerization, but several problems were found in common use of total divisions. The most important problem is, in the case of drawing information, that topographical map with building boundary and land registration map with acreage boundary cannot be used together. In the case of property information, common utilization of property information that is basically needed and standard measurement of usage classification are necessary. The characteristics of the land usage data by the rearrangement of the cadastral information. etc. is presented as the basic data for the land information orientation, and the analyzing result of the data should be expressed and controlled on the map as the fundamental survey for the establishment of the land information oriented planning supports the physical space planning of the land cadaster finally. In this research, the problem in establishing current land information around acreage of a lot was found to research data to be needed in land information for utilizationof space based digital information, and was studied the method in relation to GIS.

The major object of the Space Exploitation Act lies in defining and governing the object and definition which is distinct from the ones regulated by the Aerospace Industry Act. The concept of "space exploitation" defined in the Act is defined for that purpose. The space exploitation is defined as a comprehensive concept including the research and development of the space technology which is only enabled through the actual utilization and space exploration activities. Based upon such conceptualization, any problem related to the present legal system might be put up with, especially space exploitation being differentiated from the space industry. On the other hand, the Act is to make the international obligations derived from the international treaties be fulfilled through the minimal regulation with respect to the space activities such as space object registration procedure, the licensing regime of launching activities from the korean territory, etc.
