E-commerce represents the acquisition and sale, or the transmission of funds or data through an electronic platform. E-commerce is a paradigm shift that influences marketers and customers to improve current market processes. The significant challenges in e-commerce are the accuracy and performance factors during a business transaction, which has been substantially enhanced using Cloud Computing Techniques (CCT). The growth of e-commerce management has been increased due to massive internet penetration, and particularly small and emerging companies are increasingly using this alternative as a differentiated business model. E-commerce has significant environmental impacts and highly utilized in today's market scenario. Further, the replacement has not been thoroughly explored. Current research has been carried out to describe the e-commerce scenario to analyze market trends. This study further discusses the essential variables to the performance of market models for e-commerce. For example, e-procurement of products/services, electronic supply chain management, e-distribution and selling support (supplier connections, e-fulfilment) and online e-auctions (transactional) can represent important e-commerce capabilities, which can contribute to marketing strategy implementation effectiveness, resulting in higher export performance.

With the development of digital instrumentation and control (I&C) devices, cyber security at nuclear power plants (NPPs) has become a hot issue. The Stuxnet, which destroyed Iran's uranium enrichment facility in 2010, suggests that NPPs could even lead to an accident involving the release of radioactive materials cyber-attacks. However, cyber security research on industrial control systems (ICSs) and supervisory control and data acquisition (SCADA) systems is relatively inadequate compared to information technology (IT) and further it is difficult to study cyber-attack taxonomy for NPPs considering the characteristics of ICSs. The advanced research of cyber-attack taxonomy does not reflect the architectural and inherent characteristics of NPPs and lacks a systematic countermeasure strategy. Therefore, it is necessary to more systematically check the consistency of operators and regulators related to cyber security, as in regulatory guide 5.71 (RG.5.71) and regulatory standard 015 (RS.015). For this reason, this paper attempts to suggest a template for cyber-attack taxonomy based on the characteristics of NPPs and exemplifies a specific cyber-attack case in the template. In addition, this paper proposes a systematic countermeasure strategy by matching the countermeasure with critical digital assets (CDAs). The cyber-attack cases investigated using the proposed cyber-attack taxonomy can be used as data for evaluation and validation of cyber security conformance for digital devices to be applied, and as effective prevention and mitigation for cyber-attacks of NPPs.

Investors aim to maximize the return rate for their own investment, utilizing various information as possible as they can access. However those investors, especially individual investors, have limitations of interpretation of the domain-specific information or even the acquisition of the information itself. Thus, individual investors tend to make decision affectively and frequently, which may cause a loss in returns. This study aims to analyze analysts' target price and to suggest the strategy that could maximize individual's return rate. Most previous literature revealed that the optimistic bias exists in the analysts' target price and it is also confirmed in this study. In this context, this study suggests the upper limit of target rate of returns and the optimal value named 'alpha(α)' which performs the adjustment of proposed target rate to maximize excess earning returns eventually. To achieve this goal, this study developed an optimization problem using linear programming. Specifically, when the analysts' proposed target rate exceeds 30%, it could be adjusted to the extent of 59% of its own target rate. As apply this strategy, the investors could achieve 1.2% of excess earning rate on average. The result of this study has significance in that the individual investors could utilize analysts' target price practically.

만화는 대중매체이며 대중예술의 한 분야이다. 만화기록은 1차 문화인프라이기 때문에 팬시, 캐릭터, 게임, 영화, 드라마, 테마파크, 광고 사업 등으로 연결되어 고부가가치 산업을 창출해낼 수 있다. 그러나 국내에서는 능동적이고 체계적인 수집 절차의 부재로 해마다 소중한 만화 원고가 소실되고, 전자기록형태의 만화기록 등 보존이 힘든 콘텐츠가 늘어나고 있어 만화기록관리에 대한 대책이 절실히 요구된다. 본 연구에서는 이러한 인식을 바탕으로 만화기록에 대한 관리의 필요성에 대해 알아보고, 만화기록의 특징 및 구성요소를 분석하였다. 이와 함께 해외의 여러 만화아카이브 사례를 분석하여 만화기록의 특징을 반영한 기록관리 프로세스의 기능을 추출하였다. 이후 이들을 검토하여 기록관리체계의 틀에서 수집 관리 서비스 영역을 각각 나누어 만화기록을 관리하는 일반적인 만화기록 아카이빙 전략을 구성하여 제시해보았다. 수집을 한 만화기록은 다중분류와 계층적 기술요소를 반영하여 기록 사이의 연계를 보장하고 기록의 보존을 담보하며 다채로운 접근점을 제공할 수 있도록 한다. 지적 정리가 끝난 만화기록은 보존설비가 갖추어진 환경에서 보존처리를 하여 보존되기도 하고, 전자기록이나 훼손의 위험이 있는 기록의 경우 디지털 포맷을 사용하여 보존하기도 한다. 만화기록은 활용이 목적이기 때문에 전시 배포 기록정보콘텐츠개발을 통해 다양한 계층의 이용자에게 정보를 제공해 줄 수 있을 것이다. 만화기록이라는 용어 자체가 생소하고, 기록관리의 관점에서 연구된 바가 거의 없기 때문에 만화기록의 수집 전략이나 관리, 서비스 전략을 소개하고 간단한 예시를 보여주는 것에 그친 것이 한계점이라 할 수 있다. 그러나 기록학적 접근을 통한 만화 기록관리 전략을 만화 매뉴스크립트 보존소에 실용적으로 도입할 수 있다면 만화기록의 체계적 보존, 수집, 정리가 가능하여 훗날 한국의 문화 콘텐츠 관리에 큰 밑거름이 될 수 있을 것이다.

In this paper our main focus is to provide insight into the history of M&A's for this purpose we have analysed the different waves of M&A. We have analysed these waves in context of available literature and fact and figures. During the study we realised that almost all of the waves of M&A's ended because of financial crises, although impact and severity of that crises may differ. We analysed the impact of current crises on M&A in global context and in order to establish how companies have and in post crises era i.e. after crises of 2007 onwards how the companies have changed their corporate strategies to accommodate M&A's. We have also analysed which factors fuelled M&A's in past and were these factors present in post crises era M&A activities. By first quarter of 2011 the many firms saw new growth opportunities in M&A activities seemed to rebound as large companies used M&A's as part of their corporate strategy but this was cut short by events like US debt ceiling, down grade of USA's credit ratings along with fears about Eurozone's financial health and their impact on future prospects of M&A's would they continue to prosper or would they be weighed down by these events.

본 연구에서는 Porter의 다이아몬드 모형에 입각하여 관련 분야 전문가들의 의견 수렴을 통해 우리나라 인공지능 산업의 국가 경쟁력에 영향을 미치는 요인들에 대한 중요도를 분석하였다. 분석 결과 인공지능 산업의 국가 경쟁력에 가장 큰 영향을 미치는 요인은 연구개발, 자본, ICT 기술 경쟁력 순으로 나타났다. 인공지능 산업은 자본집약적 특성이 강한 하이테크놀로지 산업이므로 국가경쟁력 확보를 위해 무엇보다 인공지능 기술과 그 기반인 정보통신 기술에 대한 국가 R&D 역량의 결집과 인프라 구축을 위한 공격적인 투자가 중요할 것으로 판단된다. 인공지능 기술의 근간을 이루는 ICT 인프라 및 활용역량 등을 고려할 때 국내 소비자의 높은 요구수준은 인공지능 산업의 국가 경쟁력 확보에 긍정적 촉매요인으로 작용할 것으로 예상된다. 또한, 인공지능 기술은 빠른 확산속도와 강한 파급력을 지닐것으로 전망되므로 적시 대응을 위한 기업의 선제적 역량확보가 필수적일 것으로 사료된다.

Bridge collapses may deliver a huge impact on our society in a very negative way. Out of many reasons why bridges collapse, poor maintenance is becoming a main contributing factor to many recent collapses. Furthermore, the aging of bridges is able to make the situation much worse. In order to prevent this unwanted event, it is indispensable to conduct continuous bridge monitoring and timely maintenance. Visual inspection is the most widely used method, but it is heavily dependent on the experience of the inspectors. It is also time-consuming, labor-intensive, costly, disruptive, and even unsafe for the inspectors. In order to address its limitations, in recent years increasing interests have been paid to the use of unmanned aerial vehicles (UAVs), which is expected to make the inspection process safer, faster and more cost-effective. In addition, it can cover the area where it is too hard to reach by inspectors. However, this strategy is still in a primitive stage because there are many things to be addressed for real implementation. In this paper, a typical procedure of bridge inspection using UAVs consisting of three phases (i.e., pre-inspection, inspection, and post-inspection phases) and the detailed tasks by phase are described. Also, three major challenges, which are related to a UAV's flight, image data acquisition, and damage identification, respectively, are identified from a practical perspective (e.g., localization of a UAV under the bridge, high-quality image capture, etc.) and their possible solutions are discussed by examining recently developed or currently developing techniques such as the graph-based localization algorithm, and the image quality assessment and enhancement strategy. In particular, deep learning based algorithms such as R-CNN and Mask R-CNN for classifying, localizing and quantifying several damage types (e.g., cracks, corrosion, spalling, efflorescence, etc.) in an automatic manner are discussed. This strategy is based on a huge amount of image data obtained from unmanned inspection equipment consisting of the UAV and imaging devices (vision and IR cameras).

We are witnessing the growing maritime tension on the East Asian sea these days. Each naval powers in the region are competing each other to acquire more advanced naval capabilities. Based upon the rapid economic development, China is actively beefing up its naval capabilities and expand its boundary of naval activities all over the East Asian region. Chinese Navy already unveiled its expansive naval strategy replacing the traditional concept of 'Near-Sea Defense' with the new concept of 'Far-Sea Defense' strategy. In response to potential rival's naval build up, the U.S. is redeploying its naval forces focusing on the Asia-Pacific region. The U.S. enhances its joint naval exercises with the countries in the region, such as Japan, India, Australia and so on. In addition, Washington is devising new naval strategy under the concept of 'Air-Sea Battle' to deter Peking's so-called 'Anti-Access/ Area Denial(A2AD)' strategy. As a close ally of the U.S., Japan also disclosed its clear intention to strengthen the Maritime Self Defense Force(MSDF)'s capabilities by introducing the new concept of 'Dynamic Defense Force' in 2011. Under the new concept, JMSDF is pursuing the additional acquisition of submarines, quasi-aircraft carriers, Aegis-equipped destroyers, etc. Under the new president's strong leadership, Russia is also invigorating the naval build-up. Especially, Russia is fortifying the Pacific Fleet's naval assets by deploying new-type of naval ships such as the Mistral which was imported from France. In the midst of competitive naval build-up among the major naval powers in the region, we are observing the growing maritime conflicts on the East China Sea as well as South China Sea. Those naval conflicts can pose severe threats to our national interests. Maritime conflicts on the East or South China Sea can imperil our sea lanes which will be indispensible for national economic development. Neighboring countries' maritime conflicts also will cast an uncertainty on the path to mobilize international cooperation to resolve the North Korean issues. We should contribute to ease the maritime tension in the region by various ways. First, we should actively galvanize the bilateral maritime dialogue among the major naval powers in the region. Second, we also should take the lead to form a multilateral maritime cooperation mechanism in the region. Above all, we should set the aim to be a peaceful maritime power who can contribute to a building of stable maritime order in the region with a considerable naval power.
