During Khmer Rouge Regime, Cambodian pop music was completely forgotten since 90% of artists were killed. After recovering from war since 1979, the music started to grow again in 1990. However, Cambodian popular music dynamic and flows are observably directed by the multifaceted socioeconomic, political and creative forces. The major problems are the plagiarism and piracy which have been prevailing for years in the industry. Recently, the consciousness of the need to preserve Khmer original songs from both fans and artist have been increased and become a new trend for Cambodia young population. Still, the music quality is in the limit state. To increase the mind-set, the feedbacks and inspiration are needed. The study suggested a music ranking website using sentiment analysis which data were collected from Production Companies Facebook Pages' posts and comments. The study proposed an algorithm which translates from Khmer to English, doing sentiment analysis and generate the ranking. The result showed 80% accuracy of translation and sentiment analysis on the proposed system. The songs that rank high in the system are the songs which are original and fit the occasion in Cambodia. With the proposed ranking algorithm, it would help to increase the competitive advantage of the musical productions as well as to encourage the producers to compose the new songs which fit the particular activities and event.

Copyright infringement and data piracy are pervasive problems of digital era and Electronic Navigational Charts(ENC) are not free from these issues. Aside from the economic impact, the unofficial distribution of nautical information has sign띠cant safeη concerns. Therefore, official distributors of nautical information have sought appropriate methods to protect their data and to provide the mariner with a certificate of authenticity through the adoption of security schema. However, a plethora of different security schema provided by independent distributors markedly complicates the software development of Electronic Chart Display and Information Systems (ECDIS) manufacturers and makes it more difficult to achieve the goal of seamless world-wide electronic navigational database easily accessible to the mariner. A fundamental concern of IHO is that adoption of a single, centrally administered security scheme for all ENCs could improve the ease of use of ENCs and enhance safety of navigation. IHO have driven protection scheme as S-63, S-63x. NORI(National Oceanographic Research Institute) necessarily need protection scheme and supporting system for nautical information. This paper presents protection scheme for NORI and proposes support system for ENC protection.

Recently the government has succeeded in shutting down the Illegal Copyrighted Websites by cracking down on the operators of the websites. But this only caused 'the Balloon Effect', similar websites were created and users shifted to the new websites. 'Follow the money' is drawing attention as a way to complement the effect of policies. It tracks the commercialization scheme and fund flows of the Illegal Copyrighted Websites and blocks the supply and publication of advertisements, which are the main source of revenue. This approach aims at self-closure of Illegal websites by blocking the revenue source. In this study, we have selected and analyzed overseas cases that adopted these measures. Many countries had different policies and campaigns, but three things are common: non-punishment measures, partnership based on voluntary participation, pursuing a variety of purposes other than protecting the copyright industry. In Korea, the reason public-private Partnerships was not properly established had been caused by the difference of views between them. Advertisers and agencies need to expand their awareness that illegal advertisements can have adverse effects such as brand image damage and enormous economic losses. Also campaigns and conferences related with the policy should be held to prevent copyright infringement through mutual understanding and cooperation.

History, demonstrating convincingly that pirates have arisen continuously for a lengthy period of time throughout the world, is able to become a cooperative study of international law in terms of pirates matters ; Viking pirates. There are beneficial topics for the study of true nature of viking activities and the settlement of present pirates matters ; How were the pirates activities of Vikings, What sort of relations do they have between Vikings and other pirates which have arisen in world history, What are the differences compared to present concept of pirates. There were active pirates activities in the coast and waters of Scandinavia even before the period of the Migration Age because of geographical condition. With those experiences, Vikings began to ambush Britain Islands sailing across the North Sea since the late 8C, ages of migration in earnest. They ambushed all coasts of the European Continent expending boundary until the late of 11C. Pirate activities in a sort of guerrilla operations were operated when they encountered Islams in the Iberian Peninsula and the coast of North Africa. They showed twofold attitudes ; if the defence of the region and sea was weak, they plundered, or if strong, traded. In plundered europeans' position, Vikings were pirates with cruelty and barbarians. In vikings position, they were normal human beings who did a pirate activity to lead a better life. Viking pirates showed different characteristics in terms of three aspects ; area and aspect of action, activity after piracy. Meanwhile, Viking pirates showed several differences with pirates defined in terms of modern international law. Among the satisfying conditions of pirates, required by the international law of the sea, Vikings fulfilled animus furandi, desire for gain, activities for hatred and revenge, and private ends. Other conditions including attacking authority of the vessels, activities toward private ships, activities in the coast and the land, and illegal terroristic activities toward ships are found in viking pirates. However, Viking pirates do not show the activities in high seas and in the outside of a State's jurisdiction. In addition, it cannot be excluded that they pirated with vessels of regional leaders and the Sovereign, not private ships. Contrary to the definition of concept in terms of modern international law toward pirates, Viking invaded foreign waters, came on shore to foreign land and island, went up-stream the rivers to the back of interior, and attacked churches and abbeys. Strangely, they sometimes settled down in the places where they had pirated. Today, pirates appearing in history and defined in international law exist simultaneously and separately. It means, the historical nature and the nature under the international law are turning up differently. Historical cases of pirates should be reflected to modern international law. If so, it seems that the clue to solve pirate problems can be arranged. History is the immortal living thing, which not just existed as a past but reflects present.

They insist that there is no more new stuff in modern art to change every circumstance rapidly. According to this situation, they recreate the works which are made with the existed idea or materials, and also transform creative concept which cites the existing functions with modern meaning. Furthermore they can look into any data everywhere from their daily routine using the internet. And this must become one of the general forms which they imitate others' works which are referred or chosen in modern art. These social complextion is called a parody and pastich is technique of the Post Modernism which is the existence of past. Using the new construction, the parody and pastich which can accomplish some better value and bring other meanings makes original recreation with the concept of copying and repeating. It keeps changing and is shaping up to be different aspect so far. Every field has a little different term using its own expression but it keeps empathizing each other a same essential meaning. Although it is like universal mode of expression, It is fact that the public cannot distinguish what is creation, imitation, or piracy. This thesis shows the concept of it and files for terms which is using like that. At last it selects some artist who worked with parody and pastich analyses and compares them and their works.

As the main technology of the 4th industrial revolution, immersive 360-degree video contents are drawing attention. The market size of immersive 360-degree video contents worldwide is projected to increase from $6.7 billion in 2018 to approximately $70 billion in 2020. However, most of the immersive 360-degree video contents are distributed through illegal distribution networks such as Webhard and Torrent, and the damage caused by illegal reproduction is increasing. Existing 2D video industry uses copyright filtering technology to prevent such illegal distribution. The technical difficulties dealing with immersive 360-degree videos arise in that they require ultra-high quality pictures and have the characteristics containing images captured by two or more cameras merged in one image, which results in the creation of distortion regions. There are also technical limitations such as an increase in the amount of feature point data due to the ultra-high definition and the processing speed requirement. These consideration makes it difficult to use the same 2D filtering technology for 360-degree videos. To solve this problem, this paper suggests a feature point extraction and identification technique that select object identification areas excluding regions with severe distortion, recognize objects using deep learning technology in the identification areas, extract feature points using the identified object information. Compared with the previously proposed method of extracting feature points using stitching area for immersive contents, the proposed technique shows excellent performance gain.

This paper examines the American Civil Liberties Union(ACLU)'s recent legal challenge on patents held by Myriad Genetics on two genes (BRCA1 and BRCA2) associated with a high risk of breast and ovarian cancer. Instead of analyzing the ACLU's objections to the BRCA patents in terms of its legal technicalities and normative ethical principles, this paper seeks to situate this legal case in the broader historical context of the shifting understanding of the relationship between private ownership, economic development, and the public interest in academic sciences. This paper first briefly chronicles a series of scientific developments and key legal decisions involving patenting of life forms, including genetically engineered micro-organisms animals and biological materials of human origins like cell cultures and genes, that led to the US Patent and Trademark Office(USPTO)'s official guidelines on human gene patenting in 2001. At another level, this paper analyzes the expansion of the scope of intellectual property rights in the life sciences in terms of shifting economic and legal assumptions about public knowledge and its role for economic development in the 1970s. I then show how these economic, legal, and ethical ideas that linked private ownership and the public interest have been challenged from the 1990s, calling for revisions in intellectual property laws regarding a wide array of life forms. The tragedy of the anticommons in human gene patenting, according to ACLU, has severely undermined creative scientific activities, medical innovations, access to health care and rights to life among cancer patient groups. ACLU's objection to human gene patenting on several US-constitutional grounds in turn suggests issues regarding intellectual property are critically linked to vital issues pertinent to the creative communities in arts and sciences, such as free exchange of ideas, censorship and monopoly, and free expression and piracy etc.

When looking at the online copyright infringement, the advertisements have served as a revenue source. Recently, copyright holders and state agencies have requested to stop and withdraw posting the ad. in order to prevent copyright infringement. This way is very easy and efficient. However, the problem is that it is not clear whether the request is appropriate. For the request to be valid, posting the ad. should be a kind of indirect infringement, or if not, it must have a suitable reason. If there is no basis or reason for the two, the request should not be asked recklessly. In the US relevant cases, something more than simple relationship with direct infringers or more material contribution to the direct infringement is required to impose secondary liability for copyright infringement. However, just posting the ad. cannot be considered as the close relationship and moreover, it is not material contribution. Thus, posting the ad. is not secondarily liable for copyright infringement. In addition, the bills which was proposed in 2011, so called SOPA and PIPA, had a provision which can stop and withdraw the ads in the piracy sites. Its opponents raised the following problems: withdrawing the ad. is the censorship, gives the burdensome to the sites, and causes the imbalance due to the overload protection of copyright. Also, under the ad blocker case, to remove the ad. discretionally consists of illegal activity or copyright infringement. As a result, because the request to stop and withdraw posting the ad. is not reasonable, the request should be asked carefully.

After the Cold War, international terrorism and related issues have been the most urgent problems. However, Korea hasn't recognized this seriousness due to relatively slight damage. Yet the interest about the international maritime terrorism and related issues is increasing as the maritime terrorism issues emerged. This is because Korea is located next to three oceans and majority of international trades depend largely on international maritime transportation due to its scarce natural resources. Therefore this study has the purpose that it reviews the advanced researches and documents, analyzes the priority about response system against international maritime terrorism, suggests the practical solutions. For these purposes, it conducted Delphi technique to international maritime terrorism experts with response system factors selected among the advanced researches and documents. As the result of analysis, this study figured out that legal and institutional countermeasures are needed as international measures, strategic countermeasures are needed as domestic measures to set up the response system against international maritime terrorism. Synthetically, for the efficient and practical counteract against international maritime terrorism, the response institute against international maritime terrorism and the awareness of relevant experts are preferentially necessary.

We investigate factors affecting chatbot use intention of online shopping mall users. We identify theoretical foundations from the literature and postulate that accuracy, personalization level, intelligence, intimacy, social presence, and piracy concern should affect intention to use more or negative intention to use. Based on 300 responses from online shopping mall chatbot users in Korea, we run the statistical analysis to assure the reliability and validity of the measurements. From the multiple regression analysis, we find that personalization level, intelligence, social presence, and privacy concerns significantly affect intention to use more. In contrast, we find that accuracy and privacy concerns significantly affect negative intention to use. This work will present pragmatic implications upon the design and management of chatbot in order to not only incent customers to use more but reduce factors that may cause negative use intention. Among functional factors, personalization and intelligence increases the intention to use more while accuracy decreases negative intention to use. Among emotional factors such as intimacy and social presence, we find that only social presence significantly increases intention to use more. Privacy concerns is found to decrease intention to use and increase negative intention to use.
