The old sources of competitive edge and value added were land, labor, and capital. In today's knowledge-based economy in the 21st century, technology is attracting attention as a new engine of growth. That paradigm shift of world economy has resulted in the global spread of technology transfer and the gradual increase of trade of intangible goods including patents and know-how as well as tangible goods in international trade. An international license agreement is a representative form of technology transfer. In license agreements, the providers of technology keep their ownership of technology, allow the implementation of technology to the users of technology only for a certain period of time, and receive loyalty as a reward. Economic profit through such technology trade can be realized with the smooth implementation and termination of agreement. International license agreements are different from sales contracts, which represent international business transaction based on mutual obligation, in many aspects in that they target intangible goods of technology and aim for rent for a certain period of time. This study thus set out to examine issues that could be controversial in the main and individual obligation of the parties in international license agreements and provide implications helpful for the prevention of disputes in advance.

As the need for more variety of interactive media grows, alternative interaction methods beyond conventional ones such as mice and keyboards are vigorously explored recently. In particular, these new approaches are getting attentions because they can enhance the user experiences in the interaction. Howerver, since they are case-dependent and specific, it still becomes crucial to consider and evaluate the effects and possibilities of interactions. The study aims to explore the ways to design the interactions by applying Behavioral Prototyping Methods in the initial stage of design development, which it calls 'Interactive Prototyping Method'. With the case project, 'Shadow Theater', which is an interactive installation for children, children can play and participate in interactive story-making by wearing hand puppets, casting shadows of hand puppets, and interacting with virtual objects on screen. To explore and design the interactions of Shadow Theater at the initial design process, the study builds an interactive prototype which borrows puppet theater settings and lets children play with hand puppets and other objects. The session of user try-outs with the prototype help to understand what and how they interact with virtual objects, and to improve the interactions.

The most popular protein structure prediction method is comparative modeling. To guarantee accurate comparative modeling, the sequence alignment between a query protein and a template should be accurate. Although choosing the best template based on the protein sequence alignments is most critical to perform more accurate fold-recognition in comparative modeling, even more critical is the sequence alignment quality. Contrast to a lot of attention to developing a method for choosing the best template, prediction of alignment accuracy has not gained much interest. Here, we develop a method for prediction of the shift score, a recently proposed measure for alignment quality. We apply support vector regression (SVR) to predict shift score. The alignment between a query protein and a template protein of length n in our own library is transformed into an input vector of length n +2. Structural alignments are assumed to be the best alignment, and SVR is trained to predict the shift score between structural alignment and profile-profile alignment of a query protein to a template protein. The performance is assessed by Pearson correlation coefficient. The trained SVR predicts shift score with the correlation between observed and predicted shift score of 0.80.

The digital contents industry already heads toward the OSMU(One Source Multi Use) method of media. In case the success of the original novel recreates to a movie, the success of a movie is again noticed with the original novel. For this reason, a novel and movie are open at the same time, In this paper, we analyze through the case study of three fantasy films having the narrative structure of the germane myth : The Lord of The Rings, Harry Potter, The Chronicles Of Narnia based on the analysis basis : Hero's Journey 12 steps by J. Campbell, The analysis of scenes of each film visualizing the narrative structure of a novel can be used as the basic materials in the process of visualizing the scale of the original and message of a writer, we consequently believe that these analysis will be able to be applied the appropriate visual techniques (the special effect, the scene tractions, and etc.)in visualization of films.

In this study the pilot test of CGS as injection method by low slump mortar was performed and the results were analyzed in order to find out the application of this method and effect of settlement restraint. The site far pilot test is adjacent to apartments supported by pile foundations. Sand drain method was performed previously as countermeasures against settlement, but settlement occur continuously because this ground is very soft. Site investigations such as SPT, DCPT and vane shear test were performed to determine the characteristics of ground improvement. Field measurements and FDM analysis were performed on purpose to find out the displacement of ground during injection works. From the results of this study, CGS method can be optimized by the control of diagram, space, depth, injection material, and injection pressure. CGS improved soft ground compositely by the bearing effect of CGS columns and reinforcement of adjacent ground. Considering that increase of N value is about 2.1, CGS can be considered as an effective method to increase the bearing capacity as well as to stop the settlement of soft ground. It is also expected to be economic and effective in improvement of ground when it is used in applicable sites.

본 논문은 고기능 자폐 아동들이 담화 주제어 연속성(topic continuity)을 어떻게 습득하는지에 대해 검토하였다. 연구의 목적을 위하여 세 고기능 자폐 아동(9;11-12:2)의 자연 발화를 관찰 분석하였다. 사전 연구에 의하면, 자폐아동들은 의사소통의 기본적인 규칙을 잘 이해하지 못할 뿐만 아니라 타인의 사고와 기대 등에 민감하지 못하여 담화 주제를 적절히 유지하거나 전환하는(topic shift) 일에 많은 어려움을 겪는다. 본 연구는 한국 자폐아동들이 주제어의 유지와 전환 등, 담화 화용적(discourse-pragmatic) 기능의 발달 양상을 규명하는 것을 주요 목표로 한다. 본 연구의 자료는 세 자폐 아동의 자연 발화 내용으로서 1주-2주에 한번씩 매번 방문 시 120분 동안 녹음하였다. 분석 결과 다음의 몇 가지 습득 양상을 발견하였다. 첫째, 세 자폐 아동들에게서 발견된 주제 유지 빈도는 정상 아동들에 비해 낮았다. 한편. 이 아이들은 가끔 화제를 자신의 담화 주제로 돌려 자신의 주제 중심으로 대화를 지속했다. 이 아동들은 대화 상대자의 주제에 대해서는 민감하지 않지만 자신의 주제를 유지하려는 경향을 보이기도 한다. 둘째, 개별 아동을 검토한 결과, 담화 주제의 지속성이 높은 발화를 하는 아동은 현재 담화 주제에 더 민감하고 반향어를 산출할 때에도 자기 자신의 말 반복과 담화 상대자의 말을 반복하는 빈도가 별로 차이가 나지 않았다. 반면, 담화 주제의 지속성이 낮은 발화를 하는 아동은 이전 담화 주제에 더 민감하고, 반향어는 담화 상대자의 말 보다는 자기 자신의 말을 반복하는 비율이 더 높았다. 본 연구의 결과는 자폐 아동들이 담화 주제를 지속하는 능력이 많이 부족하지만, 담화 주제의 연속성은 다른 발화 유형과 상호 작용을 하면서 발달될 수 있다는 가능성을 보여 주었다. 따라서 본 연구 결과는 앞으로 자폐 아동의 연구가 집단 간의 연구뿐만 아니라 개별 아동의 발화에 쓰인 유형 간의 상호 관계를 주목함으로써 자폐 아동의 개별적 언어 치료에 새로운 시각을 심어 줄 가능성을 시사한다.

It is very important to research drivers' visual behavior. Angle of vision is very important and accounts for more than 90% as the source of driving information. In curve sections, drivers can know the front circumstances and drive more safely and comfortably through facilities guiding their eye movements. Therefore, the standards of installation and effectiveness of these facilities to guide drivers' gaze need to be reconsidered considering characteristics of drivers' eyes The national road no. 34 (Jincheon IC, Buckamri-Yiriangmun section), which is a high-accident-frequency location, is chosen for experimental place. The aim of this study is to understand the process of drivers' visual movement which is drivers' visual behavior and to check the facilities to guide their eyes. Another goal of this study is to improve facilities to guide drivers' eyes on a result basis of considering drivers' visual behavior especially for traffic safety in a high-accident-frequency curve sections.

The new Korean government sets its main policy direction as Creative Economy. The Creative Economy can be defined as a growth strategy that establishes new companies, enhances the competitiveness of established companies and creates new markets, industries and jobs in consequence of combining of creative imagination, science and technology and ICT. In this context, the concept of innovation cluster, which aims to foster technological innovations from an organic ecosystem perspective, can be a valid policy instrument for attaining Creative Economy. Innovation cluster can and must make a contribution to achieving the Creative Economy of Korea. In particular, the ICT Convergence Innovation Cluster will be a good strategy for this purpose. Based on this conceptual background, this paper analyzes a recently notable case of an ICT Convergence Cluster in Korea, Pangyo Technovalley (PTV). We argue that the Pangyo Technovalley is a representative cluster of converging ICT and science and technology. We identify the major factors for successful development of ICT cluster: regional government's flexible response to environmental change, careful pre-planning and balance between private and public involvement. In addition, we also found that additional factors, settlement condition for securing good workforce, agglomeration of various innovation actors for promoting convergence, and cluster network revitalization are also important for implementing the creative ICT convergence cluster.
