As CAS, X-ATK, and INT models considered as the most typical Air-to-Ground operation models in ROKAF are mainly designed as the voice-centered system between aircraft and ground control facilities, it is critical to newly develop the Link-16 based model for the ROK-US combined operation between F-15K, AWACS, M-SAM, and KDX-III equipped with Link-16. Former studies had been limited to the CAS operation, and they had mainly focused on reducing the voice transmission time to exchange the information between each mission step with maintaining existing operation steps. Therefore, this paper makes up the weak point in former studies, thereby designing new Air-to-Ground operation model for CAS, X-ATK, INT mission using Enterprise Architecture OV6c, which enables both aircraft and ground control facilities or between aircraft to obtain the real-time information on the location, identification, armament and the real-time image data through the broadcasting function. Based on the analysis of new operation model, we come to a conclusion that by simultaneously exchanging the information on mission between nodes concerned through the broadcasting function of Link-16. It is possible to cut down superfluous steps among the mission steps, and to reduce the mission time. It is clear that it gives rise to improve the battle efficiency and the decision-making tempo as well as the battlefield situational awareness.

Personal information includes information about a living human individual. It is the information identifiable through name, resident registration number, and image, etc. Personal information which is collected by institutions can be wrongfully used, because it contains confidential information of an information object. In order to prevent this, a method is used to remove personal identification elements before distributing and sharing the data. However, even when the identifier such as the name and the resident registration number is removed or changed, personal information can be exposed in the case of a linking attack. This paper proposes a new anonymization technique to enhance data utility. To achieve this, attributes that are utilized in service tend to anonymize at a low level. In addition, the anonymization technique of the proposal can provide two or more anonymized data tables from one original data table without concern about a linking attack. We also verify our proposal by using the cooperative game theory.

In proteomics research, the identification of differentially expressed proteins observed under specific conditions is one of key issues. There are several ways to detect the change of a specific protein's expression level such as statistical analysis and graphical visualization. However, it is quiet difficult to handle the spot information of an individual protein manually by these methods, because there are a considerable number of proteins in a tissue sample. In this paper, using database and data mining techniques, the application plan of OLAP data cube and Discovery-driven exploration is proposed. By using data cubes, it is possible to analyze the relationship between proteins and relevant clinical information as well as analyzing the differentially expressed proteins by disease. We propose the measure and exception indicators which are suitable to analyzing protein expression level changes are proposed. In addition, we proposed the reducing method of calculating InExp in Discovery-driven exploration. We also evaluate the utility and effectiveness of the data cube and Discovery-driven exploration in the lung cancer 2-DE gel image.

Failure aspects of cut-slope, which induce the sequential collapses during the excavation stage, have been analyzed. Slope rock structures are investigated by examining the orientations and positions of discontinuity planes calculated based on the BIPS image inside the boreholes. Drilled core log has been also used to identify the structural defects. Clay minerals of swelling potentials are detected through XRD analysis. Numerical analysis for slope stability has been performed by utilizing the joint shear strength acquired from the direct joint shear test. Cut-slope collapse characteristics have been studied by investigating the posture of failure-prawn joint planes and the stability of tetrahedral blocks of different sizes. Cross-section analysis has been also performed to analyze the cut-slope behavior and to estimate the amount of reinforcement required to secure the stability of cut-slope. Behavior of reinforced cut-slope is also investigated by analyzing the slope monitoring data.

Adorno's most important criticism in popular movement is the identity of revolutionary leaders and followers. The identification process has three characteristics. The first characteristic is to create a sense of solidarity within the group by creating an image more real than the antagonist and ensuring the distinction between the enemy and the comrades. Individual entities that resist the mass created by the sense of solidarity disappear, and only the subject identified with the group exists. The second characteristic is to present an optimistic utopia, which makes the public believe that salvation comes from transcendent values. This mass movement also leads to criticism of other groups or people who are deemed off-limits to their own solidarity. The third characteristic is that the public, whose individual subject disappears through the narcissism-based public hypnotic state, is identified with the conductors, and forces other subjects to hypnotize themselves. The purpose of this paper is to examine how Adorno criticizes the fascist violence of mass movements and analyze what this suggests about the task of mass movements.

하천에서 신뢰성 있는 유속 및 유량의 측정 자료는 수자원의 효율적인 계획과 관리를 위한 가장 기본적인 사항이다. 유속 및 유량을 측정하기 위해 지금까지는 주로 프로펠러 유속계나 초음파유속계 또는 봉부자 등을 활용해왔으며, 홍수 시에는 봉부자에 의존하고 있다. 봉부자를 이용한 유속 측정은 측정 환경이나 측정자에 따라 정확도 차이가 난다는 한계점이 있다. 뿐만 아니라 실제로 홍수가 발생했을 때는 유량이 매우 크기 때문에 교량으로 접근이 어렵고 현장으로의 접근자체가 제한될 수 있다. 위와 같은 문제들을 해결하기 위한 대안으로 비접촉식 유속 측정방법인 표면영상유속계(LSPIV, Large Scale Particla Image Velocimetry)가 있다. 표면영상유속계는 수면을 촬영한 영상을 분석하여 표면 유속을 측정하는 기법으로, 영상 촬영 장비와 분석 소프트웨어만 있으면 유속을 측정할 수 있다. 유속 및 유량 측정 결과를 보고할 때는 그 결과를 사용하는 사람이 얼마나 믿고 사용해도 좋은가에 관한 신뢰성을 판단할 수 있도록 신뢰도를 나타내는 어떤 정량적인 값인 불확도를 유량 측정 결과와 함께 제시하여야 한다. 표면영상유속계는 매우 간편하고 신속하게 하천의 유속장을 측정하는 기법이지만 측정 불확도 산정에 대한 연구가 미흡하여 정확한 측정 불확도를 제시할 수 없는 실정이다. 표면영상유속계의 불확도 인자는 바람의 영향, 입자 밀도/크기, 촬영시간 간격, 상관영역의 크기, 전단흐름/회전흐름, 참조점 측량/식별, 이동거리 산정 등이 있다. 표면영상유속계의 측정불확도를 제시하기 위해서는 각 불확도 인자에 대한 불확도를 제시하여야 한다. 따라서 본 연구에서는 Matlab을 이용하여 표면영상유속계의 불확도 요인 중 영상에서 참조점식별 시 발생하는 불확도를 분석하고자 한다.

Seriously depressed by the failure in the first performance of his own drama ${\ll}$The Government Inspector${\gg}$, N. Gogol sought out a space, Italy, which is obviously a turning point for the writer. Here in Italy, the writer could be able to explore an essential foundation for the national identity as well as self-identification of Russian traditional culture, all of which have already been epitomized in the Renaissance period in Italy. The city Rome itself provided Gogol with its grandness and harmonious perfectness, influencing something 'spiritual being' upon the writer. The work under discussion, "Rome," is thus created through these literary circumstances. Though it is made under the different title as "Annuntiata" and it delivers a love story between lovers, the story lines gradually turned into a fiction about the city, Rome. In comparison with city Paris, Gogol himself presents a negative view of the French metropolitan, saying that it is nothing but a by-product of the 19th century civilization. Interestingly enough, Rome for Gogol is totally different; it is the place of sublimity, that is a locus of harmonious, holy, and eternal city. Likewise, this pattern can be said of another description on the two contradictory cities: Paris and Rome. Again, Gogol fully pictures the city Paris as centripetal and Rome as centrifugal, in which the main protagonist makes the reader indulge in his own world. Throughout the story the writer tells us a transformation experienced by his character, and the work ends with an open denouement. Like Jerusalem, Rome is the city of resurrection for Gogol. Yet, this kind of possibility of transformation in the story is exposed to the hero, and it arguably depends on the extent to which he explores the readiness for encountering of 'eternity' in this "eternal city."

One of the most important research topics on intelligent transportation systems in recent years is detecting and recognizing a license plate. The license plate has a unique identification data on vehicle information. The existing vehicle traffic control system is based on a stop and uses a loop coil as a method of vehicle entrance/exit recognition. The method has the disadvantage of causing traffic jams and rising maintenance costs. We propose to exploit differential image of camera background instead of loop coil as an entrance/exit recognition method of vehicles. After entrance/exit recognition, we detect the candidate images of license plate using the morphological characteristics. The license plate can finally be detected using SVM(Support Vector Machine). Letter and numbers of the detected license plate are recognized using CNN(Convolutional Neural Network). The experimental results show that the proposed algorithm has a higher recognition rate than the existing license plate recognition algorithm.

For agricultural water management, it is essential to establish the digital infrastructure data such as agricultural watershed, irrigated area and canal network in rural areas. Approximately 70,000 irrigation facilities in agricultural watershed, including reservoirs, pumping and draining stations, weirs, and tube wells have been installed in South Korea to enable the efficient management of agricultural water. The total length of irrigation and drainage canal network, important components of agricultural water supply, is 184,000 km. Major problem faced by irrigation facilities management is that these facilities are spread over an irrigated area at a low density and are difficult to access. In addition, the management of irrigation facilities suffers from missing or errors of spatial information and acquisition of limited range of data through direct survey. Therefore, it is necessary to establish and redefine accurate identification of irrigated areas and canal network using up-to-date high resolution images. In this study, previous existing data such as RIMS (Rural Infrastructure Management System), smart farm map, and land cover map were used to redefine irrigated area and canal network based on appropriate image data using satellite imagery, aerial imagery, and drone imagery. The results of the building the digital infrastructure in rural areas are expected to be utilized for efficient water allocation and planning, such as identifying areas of water shortage and monitoring spatiotemporal distribution of water supply by irrigated areas and irrigation canal network.

In this paper, we examine the reliability verification procedure of evidence analysis tools for computer forensics and test the famous tools for their functional requirements using the verification items proposed by standard document, TIAK.KO-12.0112. Also, we carry out performance evaluation based on test results and suggest the way of performance improvement for evidence analysis tools. To achieve this, we first investigate functions that test subjects can perform, and then we set up a specific test plan and create evidence image files which contain the contents of a verification items. We finally verify and analyze the test results. In this process, we can discover some weaknesses of most of analysis tools, such as the restoration for deleted & fragmented files, the identification of the file format which is widely used in the country and the processing of the strings composed of Korean alphabet.
