국가 백년지계를 좌우하는 교육 분야 중에서도 특히 입시관련 분야는 우리나라의 독특한 풍토와 교육적 환경에 의하여 세계의 어느 지역보다도 국민적 관심은 지대하다. 그러나 제도교육권의 열악한 환경은 이러한 점을 뒷받침하지 못하고 있기에 점차 비생산적이고 비능률적인 교육 산업구조를 고착화하는 수준에까지 이를 것으로 판단된다. 또한 해마다 70만명 가량의 수험생들이 자신들의 성적 관리를 위하여 연간 4-5회 가량의 모의고사를 보고 있으며, 기존의 OMR 처리 과정을 통해 각각의 성적 분석 결과를 확인하는데 까지 적지 않은 시간을 보내야만 하는 불편함을 가지고 있다. 본 연구에서는 이러한 문제점을 해결하기 위하여 Off-Line을 통해 실시되는 모의고사를 인터넷이라는 가상공간에서도 병행하여 보다 빠르게 개인들의 성적 분석 결과를 제공하고 효과적인 성적 관리가 가능한 시스템 모델을 제안한다 제안된 시스템 모델은 시험보기 부분과 결과 확인 및 분석 부분을 둔다. 시험보기 부분에서는 출제된 시험 문제의 정답을 확인하고 결과 확인 부분에서는 처리된 정답 결과를 토대로 성적 관리를 할 수 있도록 다양한 형태의 데이터 포맷으로 분석 표현 할 수 있는 방법을 기술하였다.

Land Remote Sensing' is defined as the science (and to some extent, art) of acquiring information about the Earth's surface without actually being in contact with it. Narrowly speaking, this is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information. Remote sensing technology was initially developed with certain purposes in mind ie. military and environmental observation. However, after 1970s, as these high-technologies were taught to private industries, remote sensing began to be more commercialized. Recently, we are witnessing a 0.61-meter high-resolution satellite image on a free market. While privatization of land remote sensing has enabled one to use this information for disaster prevention, map creation, resource exploration and more, it can also create serious threat to a sensed nation's national security, if such high resolution images fall into a hostile group ie. terrorists. The United States, a leading nation for land remote sensing technology, has been preparing and developing legislative control measures against the remote sensing industry, and has successfully created various policies to do so. Through the National Oceanic and Atmospheric Administration's authority under the Land Remote Sensing Policy Act, the US can restrict sensing and recording of resolution of 0.5 meter or better, and prohibit distributing/circulating any images for the first 24 hours. In 1994, Presidential Decision Directive 23 ordered a 'Shutter Control' policy that details heightened level of restriction from sensing to commercializing such sensitive data. The Directive 23 was even more strengthened in 2003 when the Congress passed US Commercial Remote Sensing Policy. These policies allow Secretary of Defense and Secretary of State to set up guidelines in authorizing land remote sensing, and to limit sensing and distributing satellite images in the name of the national security - US government can use the civilian remote sensing systems when needed for the national security purpose. The fact that the world's leading aerospace technology country acknowledged the magnitude of land remote sensing in the context of national security, and it has made and is making much effort to create necessary legislative measures to control the powerful technology gives much suggestions to our divided Korean peninsula. We, too, must continue working on the Korea National Space Development Act and laws to develop the necessary policies to ensure not only the development of space industry, but also to ensure the national security.

is a contemporary experimental film that forms ambiguity in the narrative and the psychological motivation of the characters, destroys linear temporality, and reminds of manipulation possibilities in digital images through varied techniques, and it carries implication by the fact that the transformation process of human subjects and self-awareness are connected to social trauma and makes way to infer by comparing it to the historical contexts of other nations or societies. centers on the space outside the screen, absent space, and the intrinsic meaning within the space and the frame and shares the information in the visible space and the space outside the screen and arouses an active perceptual process so that the audience can deduce the information that is not presented. The film visualized the historical meaning without describing the background of the times in detail and aimed to express the conflicts and worries between the god, a transcendental existence, with humans, which are marginal beings, within the conflicting structure among humans. Moreover, attempted to resolve the sadness of loss and absence through the spatial aesthetics and the film presented the progression of the situation through the contrast of the characters and also the comparison between light and darkness. This study intends to make an attempt of interpreting the realm involving personal (characters) stories and the social and historical backgrounds together with the religious sphere and discuss the visualization of the semantic context. In addition, this study analyzed the sequence of the scenes in , which reconstructs identity and historical cases and religious values to observe the meaning and characteristics and closely analyze the general meaning pursued by the film. discussed the issues of trauma that individuals, regions, and nations confront as a representation and interpretation of the trauma connoted in the film, and consideration can be provided about the implication concerning the situation and context in South Korea. Furthermore, the film placidly discusses the growth and agony in humans and the society without expressing it excessively, so it will be a valuable research result to inspire the trend of creating films that incorporate new imaging technology and original visualization techniques.

21세기는 과학적 물질문명의 발달로 인하여, 과거에는 느껴보지 못했던 물질문명의 풍요를 이끌어 냈으며, 컴퓨터, 메스미디어의 발달로 인하여, 인간 문명의 관심은 지구계를 벗어나 우주론적으로 확장되어 마침내 우주시대를 열었다. 하지만 인간의 이성과 함께 영원하리라 믿었던 과학적 합리성은 20세기 초두에 제국주의적 전쟁을 일으키게 되었으며, 그로 말미암아 이성 파괴 현상이 드러나게 되었다. 급기야 20세기말에 이르러 다원주의라 칭하기도 하는 후기산업사회의 병적 증후군들, 국가간의 경제전쟁, 컴퓨터 및 각종 정보매체를 통한 신속한 정보교환의 이면에는 인간의 자기정체성의 혼돈을 아울러 초래하게 되었다. 과학기술의 발달로 생태계 및 환경은 오염되고 파괴되었다. 20세기말에는 산성비, 엘니뇨, 라니냐 현상으로 인하며, 환경의 재앙을 초래하면서 이제 인간은 문명에 대하여 여태껏 가져왔던 확고한 믿음에 회의를 갖게 된 것이다. 이와 같은 현상은 인간의 주체적 인식과 과학적 믿음의 지나친 숭배로 인하며 자연도 인간에 의하여 지배되고 인간을 위해서만 존재하는, 인간과 자연의 이원론적인 생각 즉, 인간의 이성에 의해서만 가능하다고 생각한 "근대적 주체"에 대한 맹신의 결과인 것이다. 이렇듯 20세기의 문제점은 21세기로 전가되어 여전히 계속되고 있으며, 세계내의 가장 큰 문제점은 전쟁, 기아 등 보다 이제는 오히려 환경. 생태문제로 귀결되어 지구의 생존권 자체가 위협을 받게 되었다. 미술도 서구문명의 근대주의적 영향에 의해서 모더니즘 등 이성위주의 미술인 "근대 주체적 미술"로 발전하였지만 포스터모더니즘에서 보여 지듯 이미 인간의 순수한 이성을 근간으로 한 미술에 있어서의 주체성 주장은 상당부분 무너졌으며, 이제는 장르의 해체와 다원화 현상으로 나아가게 되었다. 환경파괴에 직면하여 이제 주체는 자연이라는 타자를 새롭게 등장시킨다. 그리하여 생명중심주의, 전체론, 감각 중심주의 등 인간과 자연이 함께 공생하는 자연을 향한 생태적인 미술이 절실히 요구되는 것이다. 이에 본 연구논문은 무비판적 서구미술에 동요되지 않고, 지극히 자연적이고 동양적이기도 한 끊임없이 생명력을 창출해 내는 자연에 관심을 같게 되었으며, 환경의 중요성과 함께 생태학적 미술, 즉 생태미술에 본인의 작업을 관계시키고자 한다. 근대적 문명사에 의해 매장된 생태적 유기성의 흔적을 고고학적 탐사방법을 통하며 발굴해 내며, 환경윤리와 생태학, 심층 생태학, 북친의 '사회 생태학'을 수용하여 물질성의 생태적 복원과 함께 조형공간의 다원성에 대한 생태 미술의 일단을 규명코자 하였다.

As the 'hyper-connected society' has emerged through the 'Fourth Industrial Revolution, public interests as well as social dangers have increased. Above all, the risk of infringement of information, including confidential personal information, is dramatically increasing. As the hyper-connected society has been realized, even if only one of the internet devices is hacked, there would be a danger that the ripple effect of such a hacking spreads to the whole network. Therefore, the necessity and importance of information security, including cybersecurity, has been increasing. In other words, the stability of cyberspace and internet space is becoming more important. As a result, the Korean government is seeking to build a legal system related to information security, which would be able to cope with the information infringement problem in the hyper-connected society. However, it seems that the government is still struggling with the direction of building such a legal system. In this context, a comparative review examining the legal systems of advanced foreign countries will provide meaningful implications as to what kinds of legal policies we should devise and implement for information security. In particular, the U.S. legislative act that actively responds to the cybersecurity violations is worthy of reference. For this reason, this article systematically analyzes the current status of the U.S. cybersecurity laws. Especially, this article focuses on the "Cybersecurity Information Sharing Act of 2015"(hereinafter "CISA"), that was recently enacted by the U.S. congress. The CISA prescribes the systemic and detailed information-sharing between national and private entities. The CISA, that actively promotes information-sharing, is full of suggestions for us, in that information-sharing is an effective way to properly realize information security in today's hyper-connected society.

South Korea entered an aged society phase in 2017 with the elderly accounting for 14% or higher of the entire population. It is expected to enter a super-aged society phase in 2026. The mobility handicapped, including the disabled and the elderly, are expected to grow continuously, and the demand for transport service for the mobility handicapped will definitely increase further. Thus, there is thus a need for various research to increase the utilization rate of low-floor buses among the mobility handicapped. This study analyzed the locations of getting on and off transportation means, time of departure and arrival, purpose of use, and frequency of use by the day among the mobility handicapped by making use of the information about their use of special transport service run by the mobility support center for the mobility handicapped. The study then proposed a method of selecting locations for low-floor bus stops to reflect the distribution and need of getting on and off transportation means among the mobility handicapped with such spatial analysis techniques as geocoding, overlapping analysis, buffer analysis, and generate tessellations. Finally, the study selected 228 locations for low-floor bus stops in Cheonan and reported a need to add 35 low-floor bus stops after eliminating the ones where the locations overlapped the old ones.

Many agricultural reservoirs in South Korea, constructed before 1970, have become aging facilities. The majority of small-scale reservoirs lack measurement systems to ascertain basic specifications and water levels, classifying them as unmeasured reservoirs. Furthermore, continuous sedimentation within the reservoirs and industrial development-induced water quality deterioration lead to reduced water supply capacity and changes in reservoir morphology. This study utilized Light Detection And Ranging (LiDAR) sensors, which provide elevation information and allow for the characterization of surface features, to construct high-resolution Digital Surface Model (DSM) and Digital Elevation Model (DEM) data of reservoir facilities. Additionally, bathymetric measurements based on multibeam echosounders were conducted to propose an updated approach for determining reservoir capacity. Drone-based LiDAR was employed to generate DSM and DEM data with a spatial resolution of 50 cm, enabling the display of elevations of hydraulic structures, such as embankments, spillways, and intake channels. Furthermore, using drone-based hyperspectral imagery, Normalized Difference Vegetation Index (NDVI) and Normalized Difference Water Index (NDWI) were calculated to detect water bodies and verify differences from existing reservoir boundaries. The constructed high-resolution DEM data were integrated with bathymetric measurements to create underwater contour maps, which were used to generate a Triangulated Irregular Network (TIN). The TIN was utilized to calculate the inundation area and volume of the reservoir, yielding results highly consistent with basic specifications. Considering areas that were not surveyed due to underwater vegetation, it is anticipated that this data will be valuable for future updates of reservoir capacity information.

Recently, thank to the popularization of light-weight drone through the significant developments in computer technologies as well as the advanced automated procedures in photogrammetry, Unmanned Aircraft Systems have led to a growing interest in industry as a whole. Documentation, maintenance, and restoration projects of large scaled cultural property would required accurate 3D phenomenon modeling and efficient visual inspection methods. The object of this study verify on the accuracies achieved of 3D phenomenon reconstruction as well as on the validity of the preservation, maintenance and restoration of large scaled cultural property by UAS photogrammetry. The test object is cltural heritage(treasure 1324) that is the rock-carved standing Bodhisattva in Soraesan Mountain, Siheung, documented in Goryeo Period(918-1392). This standing Bodhisattva has of particular interests since it's size is largest stone Buddha carved in a rock wall and is wearing a lotus shaped crown that is decorated with arabesque patterns. The positioning accuracy of UAS photogrammetry were compared with non-target total station survey results on the check points after creating 3D phenomenal models in real world coordinates system from photos, and also the quantified informations documented by Culture Heritage Administration were compared with UAS on the bodhisattva image of thin lines. Especially, tests the validity of UAS photogrammetry as a alternative method of visual inspection methods. In particular, we examined the effectiveness of the two techniques as well as the relative fluctuation of rock surface for about 2 years through superposition analysis of 3D points cloud models produced by both UAS image analysis and ground laser scanning techniques. Comparison studies and experimental results prove the accuracy and efficient of UAS photogrammetry in 3D phenomenon modeling, maintenance and restoration for various large-sized Cultural Heritage.
