This research aimed to understand the current status of early childhood education and to develop a future direction of early childhood English education. One group interview and three private interviews were conducted with 10 early education teachers to obtain in-depth understanding of the problems inherent in English education. The findings show that there is an internal conflict in the teachers regarding the value of English education in early childhood. In addition, there are external conflicts with the children the parents, the English teacher, the program director, and the government in English education. It is concluded that the early childhood educators felt an internal conflict regarding the current, inappropriate execution of early English education which is lacking a suitable educational plan including goals and practices. Furthermore, the teacher's preference for English also contributed to the internal conflict regarding the belief in early childhood English education. Secondly, the external conflicts included: English teachers with inadequate understanding of comprehensive early childhood development, parents who show excessive interest in early childhood English education without regard to childhood development, the reality that early childhood English education is mostly influenced by the attitudes of the program director without regard for the conflicts experienced by the early childhood teacher, and the politics of the government continuing to ignore the reality that early childhood English education ontinues in practice without being included in the national curriculum.

The year 2010 is the 60th anniversary commemorating the Korean War. China intervened in the Korean War with the logics such as "To Resist the U.S.'s Aggression and Aid North Korea," "Save Endangered Home & defend Nation," and "If the Lips Are Gone, the Teeth Will Be Exposed to the Cold or If One of Them Falls, the Other is in Danger." However, China had a deep and long connection with North Korea through 1st Chinese Civil War, war against Japan imperialism, and 2nd Chinese Civil War. China has consulted with Kim Il-sung on his invasion of South Korea at the initial stage of development and played a casting vote role in the execution of the invasion plan. During the Korean War, the PLA supported the North Korea's regime by its action, and made the Korea Peninsula divide into two semi-permanently. Even after the war, China continues to maintain relations with North Korea by helping North Korea build the Kim Il-sung's Kingdom. Currently, whenever any issue related to North Korea rises in the international society, China definitely gets involved in those issues and exercises its power. Conditionally 'either armed aggression or, and wartime' in North Korea, China would follow the "Clause of Military Auto Intervention." In addition, China is very likely to establish refugee camps for North Koreans in the Northeastern-Three-Province and to provide rear bases or guerrilla camps for pro-Chinese sects. Furthermore, voluntarily playing a role as spokesman of North Korean Regime in the international society, China will exercise enormous influence on the reunification of the Korean Peninsula.

Nowadays, the most of commercial buildings are build-out with complex architecture and decorated with more complicated interiors of buildings so establishing intelligible escape routes becomes an important case of fire or other emergency in a limited time. The commercial buildings are already equipped with multiple exit signs and these exit signs may create confusion and leads the people into different directions under emergency. This can jeopardize the emergency situation into a chaotic state, especially in a complex layout buildings. There are many research focused on implementing different approached to improve the exit sign system with better visual navigating effects, such as the use of laser beams, the combination of audio and video cues, etc. However the digital signage system based emergency exit sign management is one of the best solution to guide people under emergency situations to escape. This research paper, propose an intelligent evacuation route GUIDE that uses the combination centralized Wireless Sensor Networks (WSN) and digital signage for people safety and avoids dangers from emergency conditions. This proposed system applies WSN to detect the environment condition in the building and uses an evacuation algorithm to estimate the safe route to escape using the sensor information and then activates the signage system to display the safe evacuation route instruction GUIDE according to the location the signage system is installed. This paper presented the prototype of the proposed signage system and execution time to find the route with future research directions. The proposed system provides a natural intelligent evacuation route interface for self or remote operation in facility management to efficiently GUIDE people to the safe exit under emergency conditions.

The aim of this project is to develop an adaptive and collective National Marine Biotechnology Plan for the next decade(2014~2023) which is able to reflect current and future changing environment. This effective strategy targets to foster marine-derived active bio-materials, marine bioenergy production technology and many promising technologies in order to promote marine biotechnology industry as a next-generation growth engine. Marine biotechnology industry based on R&D activities since 1980 has been growing as an emerging industry. This new field enables to secure exclusive patent rights and to find new potential bio-active materials from the ocean that requires long-term aggressive R&D investments. The current policy direction is to raise appropriate level of R&D investment because the current Korea's national marine biotechnology R&D fund ratio is less than 2% of the total national biotechnology R&D budget. The result shows three major strategies. First, it recommended a research implementation system and supporting policy that includes establishment of open innovation framework for the 'Industry-Academia-Research Institute Collaborations', strategic research planning and enhanced policy making process. Second, it derived state-of-the-art or new technology in many areas. Third, it formulated more detailed execution plans for successful R&D support and set up performance indicator system in related R&D program.

센서 네트워크에 이용되는 데이타 스트림 관리 시스템에서는 한정적 정보들이 개별적으로 입력되기 때문에 종합적인 결과를 얻기 위해서는 상대적인 계산 비용이 높은 조인 연산자는 필연적으로 요구된다. 데이타 스트림은 잠재적으로 무한한 크기를 가지므로 조인 연산자는 슬라이딩 윈도우 제약사항을 가져야 함은 당연하다. 또한, 종합적인 결과를 얻기 위해 조인 연산자는 여러 입력을 취할 수 있어야 한다. 이를 가능하게 하는 것이 바로 슬라이딩 윈도우를 가지는 MJoin 연산자이다. 본 논문에서는 이러한 여러 MJoin 연산자가 시스템에 등록되어 있는 환경을 가정하고, 슬라이딩 윈도우를 가지는 MJoin의 특성을 반영하여 전역적으로 공유된 질의 처리 기법인 MMJoin 기법을 제안한다. MMJoin 기법은 첫째, 전역적으로 공유된 질의 실행 계획 수릴 문제, 조인 연산 결과에 대한 윈도우 갱신 문제 및 라우팅 문제로 나누어 다룬다. 이러한 연구의 노력은 데이타 스트림 환경에서 효율적인 다중 질의 최적화 및 처리 기법의 기초연구로 활용될 수 있다.

공간 질의에 대한 선택율 추정은 가장 효율적인 실행 계획을 찾는데 이용되는 매우 중요한 과정이다. 공간 도메인이 큰 경우, 기존 연구의 요약정보는 상대적으로 적은 정보로 선택율을 추정하기 때문에 좋은 선택율을 유지하기 어렵다. 따라서, 이 논문에서는 작은 저장공간에 공간요약정보를 압축하는 새로운 기법인 MW 히스토그램을 제안한다. 이 히스토그램은 MinSkew 분할 알고리즘과 웨이블릿 변환이 결합되어 적은 저장공간에서도 타당한 선택율과 압축효과를 얻을 수 있고, 동적 갱신에 대해 효율적으로 대처할 수 있는 구조를 가진다. 실험 결과를 통하여, 버켓 수가 0.3M/6인 MW 히스토그램이 5%-20% 질의에서 평균적으로 좋은 성능을 보이고 있어, MW 히스토그램이 적은 저장공간에서 더 좋은 선택율을 얻을 수 있음을 확인시켜주었다.

행동 또는 계획이 인식적으로 실행 가능한지에 대한 지식 전제조건 문제는 그 동안 여러 연구들을 통해 정형화되어 왔다. 하지만 지금까지의 연구에서는 이러한 행동 및 계획이 실행 가능한지를 만드는 시점에서만 검사하며, 실제 수행될 때도 실행 가능할 것이라는 것을 가정하기 때문에, 시맨틱 웹에서 여러 에이전트들이 웹서비스 조합을 실행하기 위해 제한된 자원들을 공유해야 하는 분산 환경에서는 제대로 동작하지 않게 된다. 따라서 본 연구에서는 웹서비스 조합의 원자성을 보장할 수 있도록 트랜잭션적으로 수행 가능한 웹서비스 조합을 정의하고 이를 정형화한다. 이를 위해서 TL-ALCF에서 K와 A 모달 연산자를 추가하여 확장한 $TL-ALCFK_{NF}$를 제안함으로써 웹서비스 조합을 표현할 수 있는 언어인 TL-ALCF에서 인식 추론이 어떻게 수행될 수 있는지를 보인다.

As a central part in smart construction, BIM has been rapidly spread in construction industry at large. However, the level of applying BIM in construction stage is still relatively lower than that in design stage due to unclear application method, inadequate design BIM model, technical faults of BIM itself, etc. Under these circumstances, public owners inevitably need to adjust the scope and pace in BIM application considering their internal support and capabilities of contractors. This study aims to suggest major BIM-applicable tasks during construction stage in the process of establishing gradual long-term and short-term introduction strategy for public apartment housing projects. Those major tasks were identified with the combination of the importance of tasks and the future benefits of BIM using IPA method. To do so, the degrees of contribution to achieving objectives in construction, current task execution, and communication requirement were investigated by internal site managers. On the other hand, the expected benefits and current level of using BIM were assessed by BIM experts. Among operational tasks by phases, design review, construction plan review, making as-built drawing, etc. were categorized as major tasks. In addition, progress control, regular meeting, master schedule development, work inspection, on-site quality check, etc. were also drawn as major tasks by management areas. The results of this study will provide the useful reference for owners concerned about the introduction of new technologies.
