Bitcoin (BTC) is a type of cryptocurrency that supports transaction/payment of virtual money between BTC users without the presence of a central authority or any third party like bank. It uses some cryptographic techniques namely public- and private-keys, digital signature and cryptographic-hash functions, and they are used for making secure transactions and maintaining distributed public ledger called blockchain. In BTC system, each transaction signed by sender is broadcasted over the P2P (Peer-to-Peer) Bitcoin network and a set of such transactions collected over a period is hashed together with the previous block/other values to form a block known as candidate block, where the first block known as genesis-block was created independently. Before a candidate block to be the part of existing blockchain (chaining of blocks), a computation-intensive hard problem needs to be solved. A number of miners try to solve it and a winner earns some BTCs as inspiration. The miners have high computing and hardware resources, and they play key roles in BTC for blockchain formation. This paper mainly analyses the underlying cryptographic techniques, identifies some weaknesses and proposes their enhancements. For these, two modifications of BTC are suggested ― (i) All BTC users must use digital certificates for their authentication and (ii) Winning miner must give signature on the compressed data of a block for authentication of public blocks/blockchain.

본 논문은 최근 아카데미 단편 애니메이션 상을 수상하며 국제무대에서 객관적인 작품성을 인정받은 숀 탠의 애니메이션 에 나타난 은유적 표현을 분석하였다. 단편 애니메이션 은 내용적 시각적인 면에서 많은 부분이 은유적인 방식으로 표현되어 있다. 분석의 방법은 언어체계를 기반으로 하는 '개념적 은유 분석틀'을 이용하여 스토리와 시퀀스를 분석하고, 개념들이 구조화될 때 파생되는 시각적 차원을 분석하기 위하여 '시각적 은유 분석틀'을 이용하여 캐릭터를 분석하였다. 본 논문에서는 애니메이션이 관객과 소통하는 방식을 기존의 다양한 관점 중에서 은유라는 광범위한 의미에서의 언어적 대상을 통해 애니메이션이 자신을 실현하는 방식, 애니메이션이 자기 조직화하는 양상을 고찰함으로써 밝히고자 하였다. 애니메이션에서 은유는 파편과도 같은 이미지들 간의 연계와 총체성을 생산하고 관객에게 창조적 소통을 유도하는 본질적인 수단으로 기능한다. 애니메이션 에서 다양한 방식으로 실현되는 은유들의 시동 동기로서 작용하는 본질적 의미는 현대인이 느끼는 상실과 그리움의 정서이며, 열차, 병뚜껑, 음식, 물품 처리소, 좁은 틈새 공간, 소속을 알 수 없는 분실물을 통해 작품 전체를 관통하는 의미로 작용하고 있다. 이와 같이 작품 분석을 통하여 알아본 은유의 기능은 우선 미적 기능으로서 간결미와 신선미를 준다. 또한 경제적 기능으로서 장황한 내용을 함축적으로 표현하며, 여러 가지 의미를 한꺼번에 내포한다. 그리고 창조적 기능으로서 은유가 새로운 의미생산의 도구로서 사용되었다. 즉 애니메이션은 단지 어린 연령층을 대상으로 한 오락적인 장르만이 아닌 사유와 소통의 도구로서 보다 폭넓은 대중들에게 감동을 전달할 수 있는 매체이며, 이러한 다양하고 깊이 있는 의미전달을 위한 장치로서 은유적인 표현이 사용되었음을 알 수 있다.

UCC(User Created Contents) 동영상은 온라인상에서 사용자가 상업적인 의도없이 제작한 '감성 전달' 매체로서 최근 인터넷 대중문화의 핵심 콘텐츠로 급부상하였다. '감성 전달'은 UCC 동영상의 궁극적인 목적으로 '기 승 전 결'의 스토리텔링(Storytelling)이 뒷받침되어야 가능하다. 그러나 비상업적인 UCC 동영상은 불안정한 제작 환경, 다양한 변수들로 인하여 완성도 높은 작품을 기대하기 어렵다. 따라서 본 논문에서는 불안정한 UCC 동영상의 문제점을 최소화하기 위해 편집 단계에서 '세부적인 스토리텔링 편집' 과정을 제안하였다. 연구자의 실무 결과물과 UCC 동영상 공모전 수상작품을 토대로 연구한 이 제안은 공감대를 키우고, 창의적인 변화를 유도하며, 통일성있는 마무리 편집으로 작품의 완성도를 높임으로서 '감성 전달'의 기능을 확대할 수 있다.

Although information communication technology (ICT) is long regard as very useful tool in today's construction engineering and project management environment, organizations must not only operate based upon its original setting, but also requires on-going observation, additional features and fine-tuning actions before the desirable outcome can be achieved. However, it is a very common phenomenon that organizations purchase the licensed "off-the-shelf-software" package and customize it to suit their own business need. Due to the incapability of such software and inefficient customization, the possible result is making that ICT tool not user-friendly and sometimes the whole system becomes obsolete. The purpose of this paper is to review and report those actions taken (between February 2006 and December 2010) by a construction organization to enhance the performance of its Enterprise Resource Planning (ERP) system launched in December 2002. Such actions include: improving data inputting method; removing the transition bottleneck; introducing crystallization function; revising the organization's "Delegation and Limits of Authority"; publishing the "League Table" amongst users; integrating the 3D Mode into the system and upgrading hardware. Whilst the ultimate goals of such system are well beyond the time limit of this research study, an obvious interim result, achieved by this case studied organization, was winning a landmark project worth US$500 million after the ERP system was functioned properly and effectively. Their experience and success becomes an exemplar which can be borrowed by those companies, from managerial perspectives and as a roadmap, planning to adopt information technology (IT) strategy and use ICT tool in the construction engineering and project management framework. Singapore, where public housing provisions have been a major concern of their citizens as the building stock gets older.
