Information sharing is the main purpose of realizing interoperability between the application domains of Geographic Information System (GIS) and Building Information Modeling (BIM). This paper presents and describes the workflow of BIM-GIS interoperability for highway traffic information sharing. An innovative and automatic Dynamo process was presented to transfer the shapes and attributes of the shapefile from GIS to BIM. On the basis of the transformed BIM model, the detailed traffic data was added and expressed in the form of families and sheets to expand traffic information. Then, the shapes of the model were swept as solid geometries in the BIM environment applying Dynamo. The expanded BIM model was transferred back to the GIS system using the Industry Foundation Classes (IFC) scheme. The mutual communication between BIM and GIS was achieved based on Dynamo and IFC. This paper provides a convenient and feasible way to realize BIM-GIS interoperability for highway traffic information sharing according to the characteristics of highways in terms of graphic expression and model creation.

The findings of this study indicate that intangible cultural properties are worth preservation and transmission and should be considered as very important as tangible cultural properties. If the studies of intangible cultural properties are continued focusing on their characteristics and formational system, they can be expressed more properly by adding new interactive elements to database and expressive requisites. New techniques introduced in this study are believed to provide people with most reasonable and developmental motives for expression of the existing intangible cultural properties. Concerning Korea's cultural properties centered on intangible cultural properties, information construction should be made with a new idea of information based on database from the previous studies. The result will be able to set an important factor to give wide publicity to our cultural identity, which is currently shown in the process of background communication, and serve as a foothold to deliver exact information to our descendants. The intangible cultural properties are our people's mental cultural heritage resources. If museums or initiator groups, which are organized to spread cultural heritages, can use them as the subjects of exhibition through information construction and visualization, it will function to maximize the educational effect of transmitting our national mental world. The development of digital environment will provide the optimum conditions and tools making it possible to visualize intangible forms and ideas in a virtual cyber space. Given these viewpoints, steady studies and efforts for the improvement of Korea's cultural image should be made in the way of intangible cultural properties as well as tangible ones. They start from the country's accurate appreciation of cultural properties and are embodied in systematic adjustment and relationship between interdependent elements.

Nowadays Internet is the greatest and most participating media of prompting expression with 37 million users in Korea. Internet enables collective communications between social members and contributes to form sound public opinions and to develop democracy while it has negative aspect to distribute massively crime by illegal posting which is forbidden by the Criminal Act. Criminal actors who involve to diffuse information on Internet consist of three categories of information provider, user and internet service provider. Illegal posting generated on Internet is originated from IP and the criminal regulation on it is useless and meaningless because of its countless of users and ambiguous boundary with liberty for expression. Accordingly, the only criminal policy means to prevent danger by illegal posting on Internet is to regulate ISP which saves illegal posting and mediates contacts among users. In spite of it, legislation to regulate ISP is unprepared. The prudent legislative review should be done. And it should be accordance with the doctrines of propriety and vagueness of the principle of "nulla poena sine lege".

This study focused on shape attributes in a basic study that identified infographics expression diversification and delivery efficiency based on formative attributes. To achieve that goal, formative attributes were categorized as geometric or expressional type, and significant differences between them were found by identifying the attributes of each type. The study analyzed the correlations between each infographic type's formative attributes and content delivery. The results found that regularity, clarity, visibility, and content delivery were attributes of the geometric type, whereas expressionality, visibility, clarity, and content delivery were attributes of the expressional type. Further analysis of the attributes focusing on content delivery found that regularity and visibility significantly influenced content delivery for the geometric type, and expressionality and clarity significantly influenced content delivery for the expressional type. Thus, this study empirically confirmed that formative attributes of infographics distinguished between expression types with statistically significant differences during the visualization process. And that specific factors influencing content delivery were formative attributes.

Since the bio-information now even exceeds the capability of human brain, the techniques of data mining and artificial intelligent are needed to deal with the information in this field. There are many researches about using DNA microarray technique which can obtain information from thousands of genes at once, for developing new methods of analyzing and predicting of diseases. Discovering the mechanisms of unknown genes by using these new method is expecting to develop the new drugs and new curing methods. In this Paper, We tested accuracy on classification of microarray in Bayesian method to compare normalization method's Performance after dividing data in two class that is a feature abstraction method through a normalization process which reduce or remove noise generating in microarray experiment by various factors. And We represented that it improve classification performance in 95.89% after Lowess normalization.

The purpose of this study is to confirm the effect of digital co-teaching between teachers online on improving students' reading literacy. In order to achieve the purpose of the study, a pre-test was conducted on first-year high school students, and a post-test was conducted after conducting the co-teaching over two sessions. For statistical analysis, the data of 101 students with no missing values in pre- and post-tests were used. Through the OECD's PISA reading literacy evaluation framework and factor analysis, a reading literacy test tool consisting of expression, comprehension, and information literacy was developed and the degree of change in reading literacy was measured through a self-report with the tool. As a result of the analysis, it was confirmed that the digital co-teaching had a statistically significant positive effect on the expression, comprehension and information literacy of high school students. This study is meaningful in that it shows that digital co-teaching can be applied as a way to improve reading literacy in PISA organized by the OECD.

본 논문에서는 말스버그가 주장한 가보 웨이블릿을 기반으로 하는 얼굴 인식과 표정에 강인한 얼굴 인식에 대한 내용을 소개하였다. 표정을 분류하는 방법론에 대한 연구는 활발한 편이지만, 유사한 표정을 지니는 타인에 대한 구분이라던가, 동일인의 다양한 표정을 한 사람으로 정확히 인식하는 연구는 전무한 실정이다. 본 논문에서는 얼굴을 구성하는 특징 중에서 표정에 가장 많이 영향을 받는 특징을 분석하기 위한 실험과정과 결과, 그리고 근거를 제시하였고, 그에 따르는 방법론에 대한 연구를 제안한다.

인터넷 사용자의 증가로 인한 서버의 과부하 및 네트워크 응답시간 지연의 대안으로 캐시서버의 사용이 보편화되고 있다. 그러 나, 최근 유해사이트의 급격한 중가로 캐시 서버의 부가 기능인 ACL(Access Control List)또한 중요한 기능의 하나가 되면서 대량의 유해사이트 차단 목록이 캐시 서버의 병목현상을 가중시키고 있다 본 논문에서는 캐시 서버의 대명사격인 Squid의 ACL방식과 대량의 black list를 적용했을 때의 ACL의 regular expression방식의 문제점을 살펴보고, 대량의 black list에 적합한 hash기반 ACL 처리 방식을 제안한다. hash를 이용한 ACL방식은 빠른 검색을 제공하여 캐시 서버의 응답시간에 큰 영향을 주지않기 때문에 캐시서버가 정상적인 서비스를 할 수 있도록 해준다.
