Next-generation sequencing (NGS) is widely used to identify the causative mutations underlying diverse human diseases, including cancers, which can be useful for discovering the diagnostic and therapeutic targets. Currently, a number of single-nucleotide variant (SNV)-calling algorithms are available; however, there is no tool for visualizing the recurrent and phenotype-specific mutations for general researchers. In this study, in order to support defining the recurrent mutations or phenotype-specific mutations from NGS data of a group of cancers with diverse phenotypes, we aimed to develop a user-friendly tool, named mutation arranger for defining phenotype-related SNV (MAP). MAP is a user-friendly program with multiple functions that supports the determination of recurrent or phenotype-specific mutations and provides graphic illustration images to the users. Its operation environment, the Microsoft Windows environment, enables more researchers who cannot operate Linux to define clinically meaningful mutations with NGS data from cancer cohorts.

As the degree of economic development of society increases, the maintenance issues on the existing social overhead capital becomes essential. Accordingly, the adaptation of the concept of Level of service in highway maintenance is indispensable. It is also crucial to manage and perform the service level such as road assets to provide universal services to users. In this regards, the purpose of this study is to improve the maintenance service rating model and to focus on the assessment items and weights among the improvements. Particularly, in determining weights, an Analytic Hierarchy Process (AHP) is performed based on the survey response results. After then, this study conducts unsupervised neural network models such as Self-Organizing Map (SOM) and Davies-Bouldin (DB) Index to divide proper sub-groups and determine priorities. This paper identifies similar cases by grouping the results of the responses based on the similarity of the survey responses. This can effectively support decision making in general situations where many evaluation factors need to be considered at once, resulting in reasonable policy decisions. It is the process of using advanced technology to find optimized management methods for maintenance.

Dynamic route guidance (DRG) finds the fastest path from a source to a destination location considering the real-time congestion information. In Korea, the traffic state information is available by the public transportation data (PTD) which is indexed on top of the node-link map (NLM). While the NLM is the authoritative low-detailed road network for major roads only, the OpenStreetMap road network (ORN) supports not only a high-detailed road network but also a few open-source routing engines, such as OSRM and Valhalla. In this paper, we propose a DRG framework based on road network matching between the NLM and ORN. This framework regularly retrieves the NLM-indexed PTD to construct a historical speed profile which is then mapped to ORN. Next, we extend the Valhalla routing engine to support dynamic routing based on the historical speed profile. The numerical results at the Yeoui-do island with collected 11-month PTD show that our DRG framework reduces the travel time up to 15.24 % and improves the estimation accuracy of travel time more than 5 times.

본 연구는 미-중 무역분쟁을 보다 장기적인 관점에서 'G2 리스크'로 정의하고 급변하는 세계무역환경 속에서 중소기업 수출지원제도의 문제점을 진단하고 개선방안을 논의하고 있다. 중소기업 수출지원제도는 이를 총괄하는 컨트롤 타워가 부재하고, 사업별로 제도가 운용되면서 정책 간 중복으로 인해 행정적 낭비가 발생할 수 있다는 문제점이 있다. 이러한 문제를 개선하기 위해서 첫째, 중소기업 수출지원제도를 총괄하는 컨트롤 타워를 명확하게 설정해야 할 것이다. 둘째, 컨트롤 타워를 명확하게 설정한 이후 중장기 로드맵을 구축하여 중소기업 수출지원제도의 효율적인 운영방안을 마련해야 할 것이다. 셋째, 개별 수출지원조직의 역할과 책임을 명확하게 한 후 조직 간 협력을 강화할 필요가 있다. 마지막으로 중소기업 수출지원제도가 잘 수립되고 운영되고 있는지 여부를 확인하기 위해서는 올바른 성과평가기준과 환류시스템을 마련하는 것이 중요하다.

전 세계적으로 이상기후로 인한 고위도 북반부에 폭설이 빈번하게 발생하고 있으며, 폭설로 발생하는 피해액은 국내 자연재해 피해액 중 높은 실정이다. 자연재해가 다양하게 발생하고 있다. 우리나라에서는 2004년, 2005년, 2011년 강릉 및 포항 지역에서 폭설로 인한 특별재난지역으로 선포되며, 도로 제설업무 수행요령안(안)이 개정되었다. 제설방법론과 지역별 장비보유량 및 제설담당구간이 국도별로 분류가 되어있지만, 인근 시 군별 응원체계 구축은 분류가 되어있지 않은 상태이다. 다만, 자체 제설이 불가능할 경우 군부대 및 인근 사무소에 지원 및 협조 요청이라는 내용이 담겨있다. 따라서, 본 연구에서는 대설재난 발생 시 대설재난 유형 시나리오를 개발하고, 시나리오별 지역특성을 고려한 대응체계 및 응원체계 구축하는 연구를 하였다. 시나리오 도출을 위해 지역별 일 강설데이터와 재해연보 데이터를 수집하고, 유사 과거사례를 비슷한 패턴으로 분류하여 재설 GIS지도를 도출하였다. 본 연구에서는 지역별 대설재난 유형별로 분석함으로써 5단계의 시나리오를 도출하여, 지역별 제설응원체계를 구축하였다. 5단계의 시나리오는 전국(1단계), 수도권 충청권(2단계), (3단계), 영동권 호남권(4단계), (5단계)로 유형으로 도출되었으며, 그에 따른 인근 시 군 제설 응원체계 구축을 제시하였다.

WBI provides new opportunities to realize the flexible learning environment based on hypermedia and to support distance learning with a diverse interaction. The instructors or learners in WBI claim to be able to resolve reluctant fluctuations such as disorientation and cognitive overload. To overcome these phenomena, a supplementary tool able to manage learning space organized by the instructor's or learner's own way and offer effective navigation techniques is presented in this paper. A learning space management and navigation tool called HyperMap dynamically represents the learning space in the form of a two-dimensional labeled graph. This HyperMap also can be used for an instruction design tool, learner's portfolio for the exchange of learning experiences. and the assessment of WBI.

Value of rural amenity resources scattered in rural area is difficult to be assessed isolatedly. Rural Amenity Resources Map (RARM) is developed for assessing rural resources based on specific territory. In the developing process, knowledge based system is oriented because rural amenity is differed from personal feeling. Possible decision trees in RARM are developed in reviewing process of previous GIS based decision support systems, and information strategy planning is constructed for achieving goals such as rural tourism, down shifting, and rural investment.

The paper proposes a quantitative causal ordering map (QCOM) to combine qualitative and quantitative methods in a framework. The procedures for developing QCOM consist of three phases. The first phase is to collect partially known causal dependencies from experts and to convert them into relations and causal nodes of a model graph. The second phase is to find the global causal structure by tracing causality among relation and causal nodes and to represent it in causal ordering graph with signed coefficient. Causal ordering graph is converted into QCOM by assigning regression coefficient estimated from path analysis in the third phase. Experiments with the prediction model of Korea stock price show results as following; First, the QCOM can support the design of qualitative and quantitative model by finding the global causal structure from partially known causal dependencies. Second, the QCOM can be used as an integration tool of qualitative and quantitative model to offerhigher explanatory capability and quantitative measurability. The QCOM with static and dynamic analysis is applied to investigate the changes in factors involved in the model at present as well discrete times in the future.

We propose stereoscopic video coding method using the syntax of MAC(Multiple auxiliary component) that was added to the MPEC-4 visual version 2 in order to describe the transparency of the video object. We also define the novel MAC's semantics in MPEG-4 that should support the proposed coding method. The major difference between the existing coding method and the proposed coding method is the addition of the residual texture coding. The proposed coding method assigns disparity map and residual texture to 3 components of MAC: one component for disparity map and the rest 2 components fer the luminance and chrominance data of the residual texture, respectively. The performance of the proposed method is evaluated in terms of PSNR by computer simulations.
