The purpose of this study is to critically review the global intellectual property regime, which has been in full swing since the mid-1990s, from the perspective of postcolonialism. More specifically, by looking at issues which were raised by the Postcolonial Piracy Studies, it attempted to relativize the global IP system. This paper confirmed the postcolonialist view that universal concepts could never be completely universal or pure, and confirmed the non-state legalities view of media piracy as a conduit for participation in the global network through 'porous legalities' concept of Lawrence Liang. Finally, this paper raised the need to understand various relationships between the informal media economy and the formal media economy in a balanced perspective, rather than relying only on the neat dichotomy logic of illegality/legal.

최근 인구 증가, 도시화 및 산업의 발달로 인해 생활·공업용수의 수요가 증가하면서, 상대적으로 농업용수의 비율은 감소하고 있는 추세이다. 하지만 수자원이용 현황 중 농업용수는 전체 물 사용량의 48%로 여전히 가장 큰 비중을 차지하고 있다. 환경부 중심의 물관리 일원화 관련법 시행으로 국가 통합물관리 정책이 본격 추진됨에 따라 농업용수 가치의 재평가가 요구되고 있으며, 현재 수원공 확대의 경우 환경보호와 같은 이유로 농업용수 확보에 대한 많은 제약이 발생하고 있다. 공급된 농업용수 중 작물에 의해 소비되지 않고 하천으로 회귀되는 회귀수량은 하천 건천화 방지, 용수공급계획, 하천 유황예측 등 기여하는 바가 크다. 하지만 관개량과 회귀수량의 비로 나타내는 회귀율의 경우 지역에 따라 38.1%에서 70.5%로 큰 차이를 보이고 있으며, 지역별 회귀율 정량화에도 한계가 있다. 본 연구에서는 경기도 안성에 위치한 관개면적 429ha인 마둔 저수지를 대상으로 회귀율을 산정하고 농촌용수종합정보시스템 (Rural Agricultural Water Resource Information System, RAWRIS)에서 제공하는 저수지 수위 자료를 활용하여 마둔 저수지의 4월부터 9월 관개기 강수량, 저수율, 증발산량을 구축하였다. 물수지 분석 기반 회귀수량 산정모형으로부터 회귀율을 추정하였으며, 수로 네트워크 기반의 SWMM (Storm Water Management Model)과 비교를 통해 정량적인 회귀수량 및 회귀율을 산정하고자 한다. 본 연구의 결과를 통해 정량적인 회귀수량 및 회귀율 자료가 구축된다면, 농업용수의 재이용, 환경용수 및 하천유지용수, 용수공급계획 등 효율적인 농업 수자원관리에 기초자로로써 활용 가능할 것이라 판단된다.

In this study, a configuration method for a cloud technology based VoD system through two different scenarios is proposed. The first scenario virtualizes DMC, content storages for each SO, and stream servers in the conventional VoD system in order to efficiently use the additionally required storage capacity and stream server. In the second scenario, it is proposed that cable broadcasting systems including VoD systems are to be changed as cloud in which the subscriber STB should have minimum programs and storage regions to connect networks, and the operating system and middle ware presented in the existing subscriber STB is moved to the cloud data center. In addition, the comparison of the application of the cloud technology for the cost of changing the existing system to STB and the cost of establishing a cloud VoD system is performed in order to analyze the cost reduction in broadcasting businesses based on the establishment of VoD systems.

This study aims to emphasize the importance and activation of citizen oral history. As is well known, research on oral history gradually began in earnest in Korea from the 1980s. Until now, citizen interviews by researchers and elite interviews by researchers have steadily increased in quantity. However, citizen interviews by citizens are insignificant. The "Digital Life-history Archiving" project, which has been under the supervision of the Ministry of Culture, Sports and Tourism since 2021, is a new and meaningful attempt. Citizens are educated on archiving and oral history to conduct interviews and produce archives. It is producing high-quality oral archives, securing citizens' archiving capabilities, and building local cultural resources. Based on the experience of participating in this project in 2021, I evaluated the performance and limitations and looked at the implications. I expect it to help reduce trial and error in the future. I also proposed a plan to actively produce and utilize citizen oral archives. To this end, specific cooperation between oral-history institutions and oral archives platforms were also proposed.

In the MQTT protocol, if the retained flag of a message published by a publisher is set, the message is stored in the broker as a retained message. When a new subscriber performs a subscribe, the broker immediately sends the retained message. This allows the new subscriber to perform updates on the current state via the retained message without waiting for new messages from the publisher. However, sending retained messages can become a traffic overhead if new messages are frequently published by the publisher. This situation could be considered an overhead when new subscribers frequently subscribe. Therefore, in this paper, we propose a retained message delivery scheme by considering the characteristics of the published messages. We model the delivery and waiting actions to new subscribers from the perspective of the broker using reinforcement learning, and determine the optimal policy through Q learning algorithm. Through performance analysis, we confirm that the proposed method shows improved performance compared to existing methods.

As the interest in the business-to-business(B2B) electronic commerce is increasing, many companies are participating in the B2B e-Marketplaces. The e-Marketplace is defined as the virtual market that many players take part in to transact. The e-Marketplace has an influenced on the manner in which organizational buyers and sellers interact. As a result, it is important to develop an understanding of the behaviors of firms that use these electronic marketplaces. The purpose of this study is to develop a comprehensive model for trust and commitment of B2B e-Marketplace and empirically to examine their structural relationships. Drawing from trust and commitment theory in the interorganizational relationship and B2B electronic commerce context, this study identifies network externality, interactivity, justice, quality of information sharing, institutional assurance as the determinants of trust and commitment of e-Marketplace. The proposed model hypothesized that (1) trust is a function of network externality, interactivity, justice, quality of information sharing, institutional assurance, (2) attitudinal and behavioral commitment is a function of trust, (3) behavioral commitment is a function of attitudinal commitment. The proposed model is tested using organizational-level survey data from 187 buying organizations that conduct business in MRO e-Marketplaces. The data were tested by reliability test, correlation analysis, exploratory factor analysis, confirmatory factor analysis and covariance structure analysis. The results indicate that (1) trust is influenced by network externality, interactivity, justice, institutional assurance, (2) attitudinal commitment and behavioral commitment is influenced by trust (3) behavioral commitment is influenced by attitudinal commitment. Also, the empirical results confirmed that trust play a strong, central role in determinging e-Marketplace commitment. The key theoretical contribution of this research is that it begins to extend interorganizational information system literature in areas such as B2B Internet e-Marketplace. Managerially, this study contributes tn the understanding of the role of B2B e-Markeplace providers in Internet situation. And Limitations of this study and guidelines for future researches are also discussed.

This study was conducted to establish ecotourism as an introduction to sustainability and international cooperation. As a plan to retain the original meaning of ecotourism, the introduction of a program to certify/designateecotourism is being vitalized in many countries around the world. In Korea as well, an agenda to the introduction of an "Ecotourism Designation System,"which aims to ensure the quality of ecotourism at a certain level, was submitted by the Ministry of Environment to the National Assembly in June 2011, and the promotion for a demonstration program is planned this year to introduce the system. Japan has been carrying out the certification systems Good Eco-tour, which certifies the sustainability of ecotourism providers and accommodations since 2006, respectively, and has been securing the sustainability of ecotourism by enactment in 2008, as the world's first law to promote ecotourism. And the second general conference of the first Global Partnership for Sustainable Tourism(GPST) was held in Korea in March 2012, particularly, there was an agreement that the promotion of Asia and the Pacific Area Network for sustainable tourism would center around Korea, and accordingly, it is expected that Korea's status as a core country for ecotourism in the Asia-Pacific Area will increase. While the demand for an approach to natural resources is rapidly increasing, we should be active in providing an institutional strategy such as a designation system to secure the sustainability of ecotourism and seeking a plan for cooperation and network vitalization in the Asia-Pacific Area where similar natural resources and cultures are shared.
