Recently, with the diversification of media services and the development of smart devices, users have more opportunities to use digital content, such as movies, dramas, and music; consequently, the size of the copyright market expands simultaneously. However, there are piracy sites that generate revenue by illegal use of copyrighted works. This has led to losses for copyright holders, and the scale of copyrighted works infringed due to the ever-increasing number of piracy sites has increased. To prevent this, government agencies respond to copyright infringement by monitoring piracy sites using online monitoring and countermeasure strategies for infringement. However, the detection and blocking process consumes a significant amount of time when compared to the rate of generating new piracy sites. Hence, online monitoring is less effective. Additionally, given that piracy sites are sophisticated and refined in the same way as legitimate sites, it is necessary to accurately distinguish and block a site that is involved in copyright infringement. Therefore, in this study, we analyze features of piracy sites and based on this analysis, we propose an intelligent detection technique for piracy sites that automatically classifies and detects whether a site is involved in infringement.

The purpose of this research is to document and analyse spatial transformation of an unauthorized dwelling units on a peculiar site of Seoul. It's physically attached to the behind part of the west boundary wall of Chang-Duk Palace. These dwelling units took not only the site, the narrow street which had been a stream, but also the two parallel walls of others for their home. The two walls, one from the palace wall and the other from the wall of a house which distanced itself from the palace wall about 3.5 m for the reason of the Cultural Properties Protection Law, have been held as the main structural members in forming the shelter. With examining the realm of time which provide the base of the spatial realm, this research shows how the multiple linkages tangled in an illegal shack did gain and actualize an architectural language of idiosyncrasy with spontaneous order inherent in inhabitants.

The purpose of this study was to research the change of the forest in Myungseo-lee Sanchuk-myun, Chungju where most of the area managed the Swidden Agriculture(Shifting cultivation). The mountainous district should be used and developed the multi-purposing source among the agricultural field, grassland, forest, a recreational area, and an industrial site, and should be presupposed the establishment of synthetic and efficient change system. This study began to pay attention to observe the peculiarity of Swidden Agricultural area in terms of forest aspects and to broaden the outlook of Swidden Agriculture. In the status of Myungseo-lee, prior to the Project to Rehabilitate the Illegal Swidden, from 1973 to 1976, the private forest gets 110.9ha (23ha for Seodae-village, 26ha for Dooduk-village, 6ha for Myungdol-village, 41ha for Chungam-village, 14.9ha for Pangdae-village). In Myungseo-lee. millet and corn were harvested, and they performed the rotation of planting and temporary resting by changing the field. The cultivated acreage per a house of total 5 villages in Myungseo-lee was just 0.4ha in average. The 70ha of the Swidden in Dooduk-village. Myungseo-lee, was sold to the Miwon corp. and the 342ha of that in Myungseo-lee was sold to Seohae-devlp.(SK forest). Those areas afforested. As the regulation plan for the Swidden began, the people in the site got paid for 300,000won as a migration fee. The special feature of the Swidden in Myungseo-lee was that the whole migration village was already established before the regulation plan for the Swidden began, and the yield was harvested by more than other villages the use of chemical fertilizer. And, in the Swidden agriculture, it showed the well-cultivated aspect, and the major harvest was various grains. The regulation Swidden in Myungseo-lee started in 1974.

The current network environment provides a real-time interactive service from an initial one-way information prov ision service. Depending on the form of web-based information sharing, it is possible to provide various knowledge a nd services between users. However, in this web-based real-time information sharing environment, cases of damage by illegal attackers who exploit network vulnerabilities are increasing rapidly. In particular, for attackers who attempt a phishing attack, a link to the corresponding web page is induced after actively generating a forged web page to a user who needs a specific web page service. In this paper, we analyze whether users directly and actively forge a sp ecific site rather than a passive server-based detection method. For this purpose, it is possible to prevent leakage of important personal information of general users by detecting a disguised webpage of an attacker who induces illegal webpage access using traceback information

Since the government-owned land is the national property, the country is responsible for the management. Although one can see the recent activities of government to efficiently manage and maintain the government-owned land, its characteristics are not well reflected on the current managing methods. Obviously, efficient and prefer methods for the field survey is necessary for efficient management. In this study, the current management methods focused on the site srvey are analyzed and problems are deduced. Basically the current methods depending on the graphic information and cadastral survey results are compared with real illegal occupancy case. The investigation clearly shows the necessity of the cadastral survey and proved the current method is not sufficient to detect illegal occupancy on government-owned land. It is expected that this study contributes on establishing an efficient management methods for the government-owned land.

Recently, the crime that utilizes the digital platform is continuously increasing. About 140,000 cases occurred in 2015 and about 150,000 cases occurred in 2016. Therefore, it is considered that there is a limit handling those online crimes by old-fashioned investigation techniques. Investigators' manual online search and cognitive investigation methods those are broadly used today are not enough to proactively cope with rapid changing civil crimes. In addition, the characteristics of the content that is posted to unspecified users of social media makes investigations more difficult. This study suggests the site-based collection and the Open API among the content web collection methods considering the characteristics of the online media where the infringement crimes occur. Since illegal content is published and deleted quickly, and new words and alterations are generated quickly and variously, it is difficult to recognize them quickly by dictionary-based morphological analysis registered manually. In order to solve this problem, we propose a tokenizing method in the existing dictionary-based morphological analysis through WPM (Word Piece Model), which is a data preprocessing method for quick recognizing and responding to illegal contents posting online infringement crimes. In the analysis of data, the optimal precision is verified through the Vote-based ensemble method by utilizing a classification learning model based on supervised learning for the investigation of illegal contents. This study utilizes a sorting algorithm model centering on illegal multilevel business cases to proactively recognize crimes invading the public economy, and presents an empirical study to effectively deal with social data collection and content investigation.

In recent years, digital content has become easily accessible because of internet technology. Representative examples of such digital content include various types, such as music, TV, (program, sport, drama etc.) and films. However, there are cases where internet technology is used in illegal ways without the authorization of the copyright holder for digital content. Such actions have a direct impact on copyright owners' profits and further affect the development of the digital culture industry adversely. Therefore, in this study, we analyze features to detect piracy sites that cause copyright infringement. Further, we develop a piracy site detection crawler based on these features and present the analysis of its performance.

This study analyzes the physical environments of studio-housing and suggests alternative solutions for the problems of studio-housing. Based on solving the problems of it through previous research review, the research methods are decided on-site survey and the housing floor plan analysis. The results of this study are follows. First, parking lots make passengers uncomfortable. Narrow spaces between buildings cause problems in terms of light, ventilation, and privacy. Moreover, the short of green space makes living conditions less amenable. Second, the narrow corridors of studio-housing buildings bring about bad effects on walking and privacy. The living conditions becomes worse due to the illegal remodeling. Third, even though a multi-family housing provision for low or middle-income families is a good housing policy, new design policies or interventions are needed to make residents' behavior comfortable.
