As the theme of a theme park space with limited space emerged as a keyword, many experiments and research were conducted in the field. In the domestic market, not only the creation of new spaces, but also the need to develop marginalized spaces and seek complementary points through new interpretations of actual spaces, but they show physical limitations. This study newly redefined and analyzed the concept of space by approaching and interpreting virtual space as a new space. By exploring real-world examples and analyzing the results, we also derive the results that the possibility of realistic media in the virtual world is an exemplary alternative to complementing the expansion and limitations of the space. Realistic media has a wide range of content provision in selective development such as AR and VR, and the theme park's characteristic of providing various contents for quarterly concepts even if the development budget and time are small, which has a significant impact on the development of realistic media. Currently, theme parks are attracting countless majors and officials related to realistic media through metaverse. As it is attracting attention in such a new market, we look forward to seeing a lot of research and experiments in the project.

As a surveying standard of a nation, the Korean geodetic control points such as triangulation points and benchmarks require continuous and effective management toward a spatially enabled society. As the developments of information technologies, use of mobile devices like PDA (personal digital assistant) has been increasing and the Web 2.0 environment became an important part of GIS. In this context, the management systems for national geodetic control points should be upgraded in accordance with the current trend, particularly for more interactive user-interface on the Web 2.0. This paper describes the framework design and prototype implementation of a Web 2.0 GIS application for the management of Korean geodetic control points. Our system enables a real-time update of the control point information and provides aerial photos on vector maps using Ajax(Asynchronous JavaScript and XML) techniques.

다양한 수문학적 순환 성분들의 영향을 받는 유역의 포화과정은 토양층의 공간적 이질성과 맞물려 매우 복잡한 거동특성을 보이는 것으로 알려져 왔다. 이와 관련하여 주목해 볼 만한 지형인자 중의 하나로서 지형지수(topographic index)를 들 수 있다. 지형지수는 TOPMODEL의 주요한 입력변수 중의 하나로서 그 공간적 분포에 따라 유역의 상대적인 포화도를 용이하게 평가할 수 있는 객관적인 수단을 제공한다. 하지만 신뢰성 있는 지형지수의 산정은 상당히 까다로운 작업으로서 정확한 지형지수를 산정할 수 있는 절대적인 방법은 존재하지 않는 것으로 알려져 있다. 이는 지금까지 개발된 DEM을 기반으로 한 각종 흐름방향 모의기술의 수준이 아직 자연적인 지형형상을 완전히 반영하지 못함에 기인한다. 본 연구에서는 8-흐름방향방법의 단점을 보완하기 위하여 개발된 바 있는 $\infty$-흐름방향방법에 따라 지형지수를 산정하여 유역이 공간적으로 포화되어 가는 과정을 모의하여 보았다. $\infty$-흐름방향방법은 각도의 형태로 흐름방향을 산정하여 고정된 흐름방향의 구속에서 벗어남과 동시에 최소한의 흐름분산(flow dispersion) 모의를 허용하여 유역규모의 포화과정을 효율적으로 모의할 수 있는 수단으로 판단된다. 대상유역으로는 설마천 유역을 선택하였으며 지형분석 과정에는 Arc GIS를 기반으로 운용되는 software 중의 하나인 TauDEM을 적용하였다. 아래 그림은 각각 포화도 20%, 50%, 90%에 해당하는 포화역을 도시한 것으로 하천망으로 중심으로 유역이 공간적으로 포화되어 가는 과정을 효율적으로 나타내고 있음을 확인할 수 있다. 본 연구를 통하여 제시되는 방법론은 자연유역의 유출응답 속에 내재하는 동적특성이나 비선형특성에 대한 체계적인 접근을 가능하게 하는 효율적인 수단을 제공할 수 있을 것으로 기대된다.

In mobile environment supporting mobility technologies, user requirements have been increased with respect to utilization of location information. In particular, moving object DBMS has consistently posed in order to efficiently maintain traffic information related to location of vehicle which tents to tremendously change over time. Despite the fact that these sorts of researches must be taken into consideration, empirical studies on moving object in terms of map database for lbs service, spatial attribute of which is continuously changed over time, have rarely performed. Therefore, aim of this paper is to suggest efficient spatial index scheme, which is capable of supporting query processing algorithm and location of moving object over time, by developing new empirical model. As a result, we can come to the conclusion that moving object model based on multi-fixed grid index makes it possible to cut down on the number of entity for retrieving. What's more, this model enables hierarchical data to be accessed through efficient spatial filtering on large-scale lbs data and constraints in accordance with level in order to display map.

Runtime Intrusion Prevention Evaluator (RIPE), published in 2011, is a benchmark suite for evaluating mitigation techniques against 850 attack patterns using only buffer overflow. Since RIPE is built as a single process, defense and attack routines cannot help sharing process states and address space layouts when RIPE is tested. As a result, attack routines can access the memory space for defense routines without restriction. We separate RIPE into two independent processes of defense and attacks so that mitigations based on confidentiality such as address space layout randomization are properly evaluated. In addition, we add an execution mode to test robustness against brute force attacks. Finally, we extend RIPE by adding 38 attack forms to perform format string attacks and virtual table (vtable) hijacking attacks. The revised RIPE contributes to the diversification of attack patterns and precise evaluation of the effectiveness of mitigations.

This study attempts to analyze the spatial clustering of survived and closed coffee shops based on the land price and land use for each coffee shop location. The locational characteristics of survived and closed coffee shops for each cluster type are identified through various locational properties such as transport factors (physical accessibility), shop properties (franchise information, newly open/closed business experience), and spatial density (kernel density estimation). To this end, we categorize the clusters of survived and closed coffee shops into three types (general locational distribution type, commercialization type of residential area and location type of commercial center), and then analyze their locational characteristics. As the result, we found that the locations of newly open and closed coffee shops show different distribution characteristics, even though they are classified into the same type due to the double sidedness of new open and closed locations. The results of this study can be provided as basic data for planning the location of coffee shop as well as regional commercial district.

This study aims to analyze the spatial patterns of intellectual property across various regions through an in-depth analysis of intellectual property trends and their influential factors. While there's an overall upsurge in intellectual property applications in the Seoul metropolitan areas, a more detailed inspection reveals divergent patterns based on the type of intellectual property - with patent rights primarily increasing in certain non-Seoul areas and trademark rights seeing a rise predominantly within Seoul. Our findings also suggest that the growth in intellectual property applications correlates positively with improvements in public transportation accessibility, expansion of knowledge-based service industries, and a rise in large enterprises, although the relationships vary by intellectual property type. These results indicate the significant influence of geographical factors and industrial structures on knowledge-generation activities, thereby suggesting a need for region-specific policies to bolster these capacities.

The grid-type or room-and-pillar method is applied for the purpose of mining horizontally buried minerals. In this study, design and pilot test were performed to apply the room-and-pillar method which uses natural rock as a rock pillar to the construction of underground space. The area where the pilot test was conducted was in stone mine and had good rock conditions with an appropriate depth (about 30 m) to apply the pilot test. The pilot test site was selected by reviewing accessibility and ground conditions and then site construction was performed through detailed ground investigation and design. The pilot test was designed with a column shape of 8×8 m and a cross-section of 8×12 m. The blasting pattern was determined through test blasting at the site, and blasting of 3 m excavation with 89 holes was performed. Through field observations, the average width of 12.5 m and the average height of 8.3 m were measured. Therefore, it is possible to proceed similar to the cross-sectional shape considered in the design.
