This study was investigated the necessity and possibility of using block-chain technology in online used-goods trading platform. Current online used-goods trading platforms operate a safety trading system, but it is difficult to utilize due to relatively high commission rate. As a result, people mainly use the method of meeting and purchasing in person, which is a relatively costly method. This study discusses how to build a platform to solve or mitigate problems such as privacy, information distortion and omission, fraud, etc. In the platform proposed in this study, it is possible to solve the major fraud and personal information protection problems that may occur in the transaction proceeding by appropriately reflecting the types and characteristics of the block-chain technology. In future work, we will discuss legal framework and technology development plan to apply the proposed platform in this study.

Recently, the size of the mobile game market and the number of mobile game users are growing. Also, as the mobile game's life cycle is increasing at the same time, auto program issue reappears which has been appeared in PC online games. Gamers usually tend to ignore warning messages from antivirus programs and even worse they delete antivirus program to execute auto programs. Therefore, mobile game users are easily compromised if the auto program performs malicious behaviors not only for the original features. In this paper, we analyze whether seven auto programs of "clash of clans" which has a lot more users for a long time perform malicious behaviors or not. We forecast the possible security threats in near future and proposed countermeasures based on this analysis. By analyzing auto programs of highly popular mobile game of today, we can acquire the knowledge on auto program's recent trend such as their development platform, operating mode, etc. This analysis will help security analysts predict auto program's evolving trends and block potential threats in advance.

Since the last decades, livestock ranching has been fast industrialized and the global trade of meat products is sheer increasing. And the Korean government opened its domestic beef market to meet increasing domestic demand for beef. In this context, domestic beef production took its way to specialization and scale economies, and subsequently the commodity chain of beef became different from the conventional one. Such institutions as beef quality grade, HACCP, and brand marketing have strong influence on current beef production systems. Furthermore, along with the macro-scale change, regional and local systems and actors also transform the beef commodity chain. Hampyong-gun, which had once been a declining rural and under-served region in the past, is now actively reviving its economy by producing industrialized, specialized, and localized beef. Such native beef production is both impacted by and associated with multi-scaled actors, their institutions and supporting discourses. These heterogeneous actors and institutions form a newer form of native beef system in the region.

In this paper, the plans for improvement of real-time security monitoring accuracy and expansion of control region were investigated through comprehensive and systematic collection and analysis of the anomalous activities that inflow and outflow in the network on a large scale in order to overcome the existing security monitoring system based on stylized detection patterns which could correspond to only very limited cyber attacks. This study established an anomaly observation system to collect, store and analyze a diverse infringement threat information flowing into the darknet network, and presented the information classification system of cyber threats, unknown anomalies and high-risk anomalous activities through the statistics based trend analysis of hacking. If this security monitoring system utilizing darknet traffic as presented in the study is applied, it was indicated that detection of all infringement threats was increased by 12.6 percent compared with conventional case and 120 kinds of new type and varietal attacks that could not be detected in the past were detected.

인간의 주요한 경제행위로서의 어업은 현재 전세계에 걸쳐 여러 가지 문제들로 많은 어려움을 겪고 있는데, 그 가운데서 주된 내용이 자원유지와 어업행위와의 조절이다. 이에 따라 어업문제에 대한 해결과 지속적인 어업 발전의 실현에 대한 열망으로 세계 각지에서는 각기 다른 학문영역, 예를 들면 생물학, 경제학, 사회학 등 각 분야의 전문가들이 모여 생태보호 주의적 접근법(Conservation-minded techniques)이나 시장 기구에 의한 방법(Market-based instruments), 그리고 공동체에 기초한 관리(Community-centered approaches) 등과 같은 여러 가지 어업관리정책을 제시하고 있다. 이러한 여러 접근 방법 중에서 현재 세계적으로 폭넓은 지지를 받고 있는 것이 재산권에 기초한 ITQs과 협동어업관리제도(Co-management)이다. ITQ제도는 어업행위에 대한 사적 재산권의 설정을 근간으로 한다. 그러나 어업자원은 회유성이라는 자원의 본질적 성질에 의해 진정한 의미의 사유화는 어렵다. 따라서 어업자원은 완벽한 사유화가 이루어진다 하더라도 특히 어업 인구가 거대한 지역 또는 자원이 한정된 국가에 있어서는 충허용어획량의 개별 할당량이 어업에 있어서 규모의 경제와 같은 경제적 운영을 도모해 나가기에는 너무 적을 수도 있다. 그렇다면 여기에서 어떻게 어업관리를 합리적으로 운영하면 ITQ의 제도적인 이점을 이용하고, 동시에 ITQ제도의 경제적 제약을 극복할 수 있는지에 대해서 묻게 된다. 본 연구의 주목적은 이러한 의문으로부터 출발한 것으로, 협동어업관리제도에 의한 어업 할당량의 공동소유는 ITQ제도의 경제적 약점을 제거하는 동시에 그 이점을 누리는 최고의 해결책이 될 수 있다고 보고, 다음과 같은 내용에 대해 고찰하였다. 어업 문제의 본질은 어떻게 인식되는가, 어업문제 해결의 전통적 방식과 새로운 패러다임은 무엇인가, 그리하여 본 논문에서는 결론적으로 어업문제 해결의 새로운 패러다임으로서 협동어업관리 제도의 본질을 이해함과 아울러 재산권에 기반을 둔 협동업관리 제도의 통합모형을 제시하였다.

The Government R&D budget for 2019 exceeded 20 trillion won in order to develop future growth market such as basic research investment and creation of growth engine. As such, the importance of R&D investment is increasing, and various schemes for enforcing efficient and transparent business expenses are being expanded. However, research expenses (Charge ratio) such as fraudulent execution of funds are continuously being generated, and a system of imposition of sanctions is being introduced. In this paper, the legal grounds of sanctions, comparative review of laws and regulations between the ministries, and the criteria of imposition (imputation) were analyzed. In addition, since the amendment of the standard for imposing the intergovernmental surcharges, a single standard has been applied, and the transition process of the surcharging system has been reviewed. As a result of the data analysis, it was found that they focused on micro - utility activities and suggested new policy measures corresponding to them.

This essay provides a legislative perspective on conflict-of-laws issues in the area of antitrust law. A consistent focus on the affected market question of applicable law is possible and yields content and acceptable results. The law applicable to damages claims should follow the law applicable to the antitrust relation itself. It is problematic, however, where more than one market is affected. In my view, the European perspective provides one general lesson for us. We are not yet prepared to accept american-style of class action in the field of antitrust law, at least until the european have made their legislative decision. Nevertheless we should make our antitrust system more effective, so that it would have strong deterrence to anti-competitive conducts. In this paper I present a proposal for adoption of a international conflict of law instrument, possibly a regulation, on damages actions for breach of art. 32 Korean Anti-trust Law.

As the online game market grows, the use of game bots is causing the most serious problem for game services. We propose a harvest coordinate analysis model to detect harvesting bots among game bots of the Massively Multiplayer Online Role-Playing Games(MMORPGs) genre. The proposed model analyzes the player's harvesting behavior using the coordinate data. Game bots can obtain in-game goods and items more easily than normal players and are not affected by realistic restrictions such as sleep time and character manipulation fatigue. As a result, there is a difference in harvesting coordinates between normal players and game bots. We divided the coordinate zones and used these coordinate zone differences to distinguish between game bot players and normal players. We created a dataset with NCSoft's AION log and applied it to a random forest model to detect game bots, and as a result, we derived performance with a recall of 0.72 and a precision of 0.92.

The concern of Software Product Line(SPL) engineering is spreading widely because the program or product developers are able to satisfy the customer's demands quickly and give a way to handle maintenance efficiently. SPL is a reuse paradigm that reuse common parts and adopts variable parts optionally to form a differentiated product by analyzing domains. Purposes of this paper are to design an architecture which has a dynamic reconfiguration function and to develop basic components which are the basic unit of reconfiguration to raise the reuse level of the guided weapon system using the SPL. Initially we design an architecture and define basic components for developing a dynamic reconfigurable components based on SPL. Then we develop the composer for physical components and behavior components referenced by behavior models of OneSAF.
