R&D Strategic Planning plays a crucial role in determining success or failure of R&D. However, current automatic services for supporting the purpose merely provide fragmentary quantitative/qualitative analytics, and force domain experts to carry out further manual analysis by themselves. Thus, this study aims at automatically supporting R&D strategic planning with efficiency and effectiveness. To achieve the goal, we design major services in the viewpoint of the relationship between technology and R&D actor, which are essential elements in R&D. 'Trends and Predictions', 'Technology Levels', 'Relationship Paths', 'Roadmaps', and 'Competitors and Collaborators' services were designed and implemented on about 15 millions papers and patents. Future works will include the support of higher level in the hierarchy of strategic intelligence.

It is very important to measure the displacement of a structure to evaluate the safety of the structure. This study shows a methodology to measure the displacement to determine the stability of a structure when it is damaged by loads. The methodology used Moiré's phenomenon and was verified through experiments. The experiments utilized pipes to simulate the pipe supports in the construction site and measured the vertical displacement of the Moiré interference patterns according to the horizontal displacement of the pipes. Experiments confirmed that the linear relationship between horizontal displacement of pipes and vertical displacement of Moiré patterns and derive a relational expression. In conclusion, the methodology presented in this work allows us to simultaneously measure a number of vertical members' displacements regardless of distance and determine the safety of the structure.

다중 객체 추적이란 컴퓨터 비전의 한 분야로, 주어진 비디오 시퀀스 내에서 관심 있는 객체들을 추적하는 것을 말한다. 다중 객체 추적 시스템은 감시 시스템, 사용자 행동 인식, 스포츠 중계, 비디오 회의와 같은 다양한 응용 분야에 핵심 기반 기술로 쓰이고 있어 그 중요성이 매우 크다. 본 논문은 감시 목적의 다중 객체를 추적하는 방법에 대하여 다룬다. 감시 시스템의 특성상, 객체의 외관이나 움직임 등에 대한 가정을 하기가 어렵다. 따라서 본 논문에서는 크기, 색, 형태 같은 객체의 단순하고 직관적인 외관 특성을 이용하면서도, 객체들끼리 부분적으로 혹은 완전히 겹쳐졌을 때에도 객체들의 위치를 적절히 추적할 수 있는 방법을 제안한다. 본 논문에서 제안하는 방법은 객체들의 경로에 대한 정보를 유지하는데 그래프 구조를 이용한다. 그래프를 확장하고, 제거하여 영상에 대한 정보를 추론한다. 크게 보면 객체들을 영역 레벨, 객체 레벨 두 단계에 걸쳐 추적한다. 영역 레벨에서는 각 객체들이 있을 수 있을만한 영역에 대한 가설을 세우고, 객체 레벨에서는 각 가설에 대한 검증을 한다. 제안된 방법은 직관적인 정보만을 이용하여 서로 다른 형태의 객체를 빠르게 추적할 수 있음을 보여준다. 다만 객체의 외관 정보만을 이용하였기 추적하기 때문에, 객체가 다른 객체에 의해 완전히 가려진 채 또다시 다른 객체와 겹쳐지면, 정확한 추적이 되지 않는다. 이를 해결하기 위해서는 객체가 겹쳐졌을 때, 그 관계에 대한 정보를 모아야 하는데 이는 향후 연구를 통해 해결하고자 한다.

Transmedia storytelling is that a number of contents based on various media platform establish a world, and refereed as newly appeared mode in the age of digital convergence. Transmedia storytelling, each different media organically creates and produce various meaning to create a world, makes alteration in not just only producer's area but also consumer's area. The first property of Transmedia storytelling is joint producing in creation and intelligence collectiveness for enjoyment. The second property is the differentiation of story through crossover and combination, which offer new experience and penetration to consumers. As last property, it is the process of collecting and transpiring story by making relationship to establish that world. Such properties of Transmedia storytelling will act as an analysing base for transmedia contents establishing through various media platform.

The long lasting world-wide recession and low economic progress have made it more important to predict future economic behavior. Accordingly, it is of interest to explore useful leading indicators, correlated with policy targets, to predict future economic growth. This study attempts to develop a model to evaluate the performance of consumer survey results from Statistics Korea to predict future economic activities. A statistical model is formulated and estimated to generate predictions by utilizing consumer expectations. The prediction is found improved in the distant future and consumer expectations appear to be a useful leading indicator to provide information of future real growth.

Crowd-funding platforms, which enable to collect funds from individuals, have recently gained growing interests around the world. This study intends to provide future research directions for the crowd-funding by reviewing past research works. For this purpose, two research themes are selected - (1) motivations to participate in crowd-funding and (2) critical success factors for the project funding. The motivations are analyzed from both perspectives of fund demanders and suppliers. The critical success factors are investigated by using four dimensions: fund demanders, fund suppliers, relationships between demanders and suppliers, and project characteristics. Using the implications found from the past research, this paper offers future research issues necessary for the growth of crowd-funding platforms.

The purpose of this study was to analyze the relationship between maternal attachment and discharge against advice in high risk infants and determine the factors which affect discharge against advice. Data of this study were collected by means of reviewing the medical records of 127 in-patients who were diagnosed as high risk infants in admission and interviewing of the mothers of these patients was done by telephone. The high risk categories were neonatal hyperbilirubinemia, congenital anomaly, congenital heart disease, blood disorder, neonatal infection and birth injury. Maternal attachment was measured by deviding the subjects into 2 groups, the one the continuing treatment group and the other the discharge against advice group. Maternal attachment is determined by an interplay of maternal attitude and specific infant behaviors. Maternal attachment developes through continuous physical and psychological contact between mother and infants. Later it developes into maternal love. The results were as follows: 1. There was a significant association between maternal attachment and discharge against advice, that is, the attachment score was higher in the continuing treatment group. 2. Inspite of controlling medical insurance, severity of disease and the length of stay, it was found that there continued to be either a partially significant or fully significant relationship between maternal attachment and discharge against advice. Stepwise multiple regression revealed that maternal attachment was second in importance as a predictor of discharge against advice, which indicates that maternal attachment was a significant predictor of discharge against advice. 3. Stepwise multiple regression revealed that in 32.3％ of these cases the significant predictors of discharge against advice were length of stay, maternal attachment, delivery type, feeding type and income.

In recent days, the issues regarding the artists' status as labor and improvements of laboring circumstances, creating the well-fare system for artists are raised in our society. This paper searches for the process of various artists unions which are performing the important roles in the musical theatre industry in the U.S.A. The artists unions have developed the bargaining contracts and strengthened the protection of their original works. The discussions among many unions provide useful information to the independent artists when they make contracts in our Korean musical theatre market.

본 논문은 웹에 산재되어 있는 OWL/RDF(S) 도메인 온톨로지에 대한 검색 시스템을 설계하여, 온톨로지의 재사용성을 극대화 하는데 그 목적이 있다. 컴퓨터와 인간이 정보를 공유하고, 의미적인 상호작용을 위한 시맨틱 웹에 대한 연구가 활발이 진행되고 있다. 시맨틱 웹을 실현하기 위해 개념들의 정의와 개념들간의 관계를 형성하는 온톨로지의 구축이 필수요소가 됨에 따라 온톨로지를 구축하기 위해 OWL, RDF(S) 그리고 DAML+OIL 등의 많은 온롤로지 언어가 개발되었고, 이들 언어를 기반으로 하는 Protege, OILEd와 KAON 등의 사용자들에게 온톨로지 구축의 편리성을 제공하는 온톨로지 구축 도구들도 50여가지 이상 개발되었다. 이러한 이유로 많은 온톨로지들이 개발되고 있다. 그렇지만 온톨로지의 가장 큰 특징은 동일 도메인의 온톨로지의 재사용인데, 산재되어 있는 온톨로지들을 검색하기 어렵고, 이들을 한데 모아놓은 저장소 또한 갖추어지지 않아 동일한 도메인 온톨로지가 존재할지라도 새롭게 온톨로지를 구축해야한다. 이에 본 논문에서는 웹상에 존재하는 온톨로지들의 검색을 용이하게 하여 지식 정보의 재사용을 최대화하기 위하여 본 연구를 진행하고 시스템을 설계하였다.

Recent construction industry is going through much change as getting high-quality, high-technology and environment-friendly, and a safety countermeasure is required urgently as construction structures become larger and more complex. But, Safety management was ignored under quantity-oriented construction policy and that has led to large-scale accidents. Recently, interest for safety management and effective construction of safety management system has been enhanced. Therefore, in this study, we constructed safety management system using Mobile GIS for effective building safety management. As the result, we proposed a method which can manage buildings quickly and effectively as performing data accessibility, storage, and analysis directly in the field.
