CHILL96 is recommended as development language for telecommunication systems by ITU-T. In this paper, we describe the design and implementation of CHILL96 compiler using C++ intermediate code. Translation rules from CHILL96 to C++ are designed for code generation. The CHILL96 compiler is composed of four parts such s syntax analyzer, visibility checker, semantic analyzer and code generator, and each part has very close relationship with symbol table and abstract syntax tree. Performance evaluation has been performed for feasibility study. After performance evaluation, we conclude the CHILL96 compiler using C++ intermediate sho good performance compared with other CHILL compilers. In addition to high performance and portability, the CHILL96 compiler using C++ intermediate code helps application developers to maintain and enhance telecommunications software by translating CHILL96 program to C++ program.

The academic information analysis service is including automatic recommendation of reviewers and analysis of researchers' accomplishments. The service of recommendation of reviewers should be processed in a transparent, fair and accountable way. When selecting reviewers, the following information must be considered: subject of project, reviewer's maj or, expertness of reviewer, relationship between applicant and reviewer. The analysis service of researchers' accomplishments is providing statistic information of researcher, institution and location based on accomplishments including book, article, patent, report and work of art. In order to support these services, we designed ontology for academic information, converted legacy data to RDF triples, expanded knowledge appropriate to services using OntoFrame. OntoFrame is service framework which includes ontology, reasoning engine, triple store. In our study, we propose the design methodology of ontology and service system for academic information based on OntoFrame. And then we explain the components of service system, processing steps of automatic recommendation of reviewers and analysis of researchers' accomplishments.

Scene boundary detection is important in the understanding of semantic structure from video data. However, it is more difficult than shot change detection because scene boundary detection needs to understand semantics in video data well. In this paper, we propose a new approach to scene segmentation using contextual information in video data. The contextual information is divided into two categories: local and global contextual information. The local contextual information refers to the foreground regions' information, background and shot activity. The global contextual information refers to the video shot's environment or its relationship with other video shots. Coherence, interaction and the tempo of video shots are computed as global contextual information. Using the proposed contextual information, we detect scene boundaries. Our proposed approach consists of three consecutive steps: linking, verification, and adjusting. We experimented the proposed approach using TV dramas and movies. The detection accuracy of correct scene boundaries is over than 80%.

본 연구에서는 시각적으로 제시되는 단어 자극의 의미 관련성의 차이에 따라 좌우반구의 처리가 어떻게 이루어지는지 알아보고자 하였다. 이를 위해서 명칭성 실어증 환자와 정상인 대학생 피험자를 대상으로 점화 어휘판단 과제를 수행하였다. 이 연구의 기본 논리는 명칭성 실어증 환자의 왼쪽 뇌가 손상되어 있기 때문에 어떤 정보처리가 왼쪽 뇌에서 일어나는 것이라면 정상인과 명칭성 실어증환자간의 수행에서 어떤 차이가 나타날 것을 기대되는 반면, 만일에 우뇌에서 처리되는 것이라면 정상인의 과제 수행 형태와 명칭성 실어증 환자의 것이 일치하는 형태를 보일 것이라는 것이다. 실험 1에서는 수직적 범주관련성이 어느 반구에서 정보처리 되는지를 조사하였다. 그 결과 정상인은 좌반구에서 유의미한 점화효과가 있고 우반구에서는 점화효과가 없었던 반면에, 명칭성 실어증 환자는 정상인과 정반대의 점화 효과를 보이고 있다. 이러한 결과는 좌반구가 일차적으로 수직적 범주 관련성 정보처리와 관련이 있음을 시사해 준다. 또한 수평적 범주 관련성에 따른 실험 은 정상인과 환자 두 집단 모두 수평적 범주관련성이 우반구에서 처리되는 유사한 패턴을 보여주었다. 실험2에서는 연합적 범주관련성에 따른 두 집단간의 점화 효과를 비교하였다. 정상인 집단과 환자 모두 좌우반구에 점화효과를 보여주고 있지만, 정상인 집단의 경우에는 우반구에서, 환자는 좌반구에서 점화량이 더 컸다. 연합관련 정보처리는 좌우반구 모두에서 일어난다고 하는 기존의 견해와 관련하여 볼 때 연합관련 정보처리는 좌우반구에서 일어난다고 해석할 수 있을 것이다. 명칭 실어증 환자의 정보처리는 정상인과 다르게 이루어지므로 이러한 좌우반구에서의 차이가 난 것으로 볼 수 있다. 이상의 실험1과 2의 결과를 종합해 보면, 시각적으로 제시되는 단어의 범주적 관련성이 주는 어휘정보 처리는 반구에 따라 처리하는 기능이 다르다고 결론 내릴 수 있다. 즉, 좌반구는 수직적 범주 관련성을 담당하고 우반구는 수평적 관련성을 담당하며, 연합적 관련성은 좌우반구 모두에서 정보처리 된다는 것이다.

Public open data is a database or electronic file produced by a public agency or government. The government is opening public data through the open data portals and individual agency websites. However, it is a reality that there is a limit to search and utilize desired public data from the perspective of data users. In particular, it takes a great deal of effort and time to understand the characteristics of data sets and to combine different data sets. This study suggests the possibility of interlinking between data sets by analyzing the common relationship of item names held by public data. The data sets are collected from the open data portal, and item names included in the data sets are extracted. The extracted item names consist of formal context and formal concept through formal concept analysis. The format concept has a list of data sets and a set of item name as extent and intent, respectively, and analyzes the common items of intent end to determine the possibility of data connection. The results derived from the formal concept analysis can be effectively applied to the semantic connection of the public data, and can be applied to data standard and quality improvement for public data release.

This study was conducted to get forest scenic beauty management information toward forest working systems; characteristics in Larix forest stands. 35 different alternatives were simulated to visualize on basis of actual forest working methods. The options were illustrated as photos produced by computer software. Each alternatives were evaluated by 3 groups with total 593 respondents after reliability test. Visual preference evaluation was used 1 - 10 point rating scale. The ratings were scaled using SBE analysis program of RMRATE. To compare the relationship of visual preference and image scale, Spatial images of 13 thinning alternatives were measured by Semantic differential scale. In general, the respondents preferred refreshing and ordering forest stand after forest working to natural forest stand before forest working. Visual preference decreased with the increasing intensity of bare ground area and slash area in forest stand. And also, visual preference was high related to tree density, clear length of stem, and ground vegetation. Farm line of small clear cutting area was preferred straight line to curve line. Visual preferences were significant differences in certain socioeconomic variables of the respondents. Results indicate how to conduct forest working system for forest scenic beauty management.

The purpose of this study is to develop data base and interface for sofa consumers and sofa designers. The human sensibility ergonomics method was used to find the consumer needs and Quality Function Deployment (QFD) method was used to extract the designing characteristics required for sofa production. About 200 words and 100 images were gathered from sofa and furniture related catalogs and internet sites to find the best emotional words and images that can express the various sofa aspect. Among the collected words and images, 34 emotional words were selected for sensibility experiment according to the opinions of experts, relations of closeness and frequency of use, and 50 images were selected for the experiment by the diversity. Selected words and images were used for the semantic differential method with 94 subjects, and sensibility characteristics of sofas were defined through various statistical analysis methods including basic statistical analysis, factor analysis and multi-dimensional scale. In reflecting design characteristics of sofas, design factors of sofas were divided into backrest, seat, armrest, neck support and leg, and relative importance of each factor for design was determined with analytic hierarchy process (AHP) by utilizing the experts' opinions. Based on the results above, relationship analysis between emotional evaluation results and design factors was performed. Also, as various sofa images are presented diagrammatically through multidimensional scaling method, it can be used as an important tool for the development of sofa design. This study will contribute improving the product quality of sofas as it enables applying consumer needs into the sofa design.

Recently, A computing environment are provided that can easily be used for services based on the cloud environment. Among them, SaaS(SoftWare as a Service) is that it provides cloud users to be available by placing the cloud systems on the Internet software. But, the problem with this, problems is that user can not be utilized to not find a service registered in the cloud system. The thing to make clear the meaning and relationship between services using the ontology to solve these problems, It must be supported to be used to find the exact service the user wants. Ontology for service discovery can be used to help to find services by guessing relevance by using the function or service names entered by the user. We provide how to configure the service ontology and the search system of services using ontology.
