This study uncovered ambiguity and inconsistency of the semantic relationships of the existing thesaurus by analyzing the concept relationships of AGROVOC and proposed the concept relationships of ontology in partially overcoming these limitations. By the results of analyzing the concept relationships, the study proposed conceptual model as most important part of conecept relationships of ontology and semantically developed concept relationship types. These relationships partially can perform inferences and must be useful for information knowledge system based on more exact semantic relationships. Also the study found out new relationship types and they will be useful for extension of the concept relationships of existing thesaurus. And these relationship types showed that they were useful for the existing thesaurus as Legal Thesaurus.

It is necessary to manage, forecast and prepare agricultural production based on accurate and up-to-date information in order to cope with the climate change and its impacts such as global warming, floods and droughts. This study examined the applicability as well as challenges of the object-based image analysis method for developing a land cover image classification algorithm, which can support the fast thematic mapping of wide agricultural areas on a regional scale. In order to test the applicability of RapidEye's multi-temporal spectral information for differentiating agricultural land cover types, the integration of other GIS data was minimized. Under this circumstance, the land cover classification accuracy at the study area of Kimje ($1300km^2$) was 80.3%. The geometric resolution of RapidEye, 6.5m showed the possibility to derive the spatial features of agricultural land use generally cultivated on a small scale in Korea. The object-based image analysis method can realize the expert knowledge in various ways during the classification process, so that the application of spectral image information can be optimized. An additional advantage is that the already developed classification algorithm can be stored, edited with variables in detail with regard to analytical purpose, and may be applied to other images as well as other regions. However, the segmentation process, which is fundamental for the object-based image classification, often cannot be explained quantitatively. Therefore, it is necessary to draw the best results based on expert's empirical and scientific knowledge.

Objective: This study was to evaluate the effectiveness of an individually tailored program based on self-measurement of blood glucose on health behavior and HbA1c in diabetes and pre-diabetes patients. Methods: The program consisted of seven sessions for 12 weeks which were carried out every two weeks. Almost all sessions were progressed on untact method except for the first and last session. The 71 subjects were assessed for their knowledge of diabetes, health behavior, the experience of self-measurement of blood glucose, body mass Index (BMI) and hemoglobin A1c (HbA1c) at before and after the program. They were also evaluated on their degree of utilization of blood glucose measurements after the program. Results: Each mean score on their knowledge of diabetes, health behavior and the experience of self-measurement of blood glucose was significantly increased from 14.77, 25.50, and 2.70 to 15.41, 28.40, and 4.81, respectively. Each mean score on both BMI and HbA1c (n=53) was significantly decreased from 24.47kg/m² and 7.27% to 24.01kg/m² and 6.67%, respectively. The post-HbA1c had a significant negative correlation(r=-0.415) with the degree of utilization of blood glucose measurements. The degree of utilization of blood glucose measurements had a significant positive correlation(r=0.581) with post-health behavior. Conclusions: The program shows effectiveness in improving HbA1c in Type 2 diabetes and pre-diabetes patients. The post-HbA1c might be related to the degree of utilization of blood glucose measurements which might be related to the health behavior.

RDF is widely used as the ontology language for representing metadata on the semantic web. Since ontology models the real-world, ontology changes overtime. Thus, it is very important to detect and analyze changes in knowledge base system. Earlier studies on detecting changes between RDF models focused on the structural differences. Some techniques which reduce the size of the delta by considering the RDFS entailment rules have been introduced. However, inferencing with RDF models increases data size and upload time. In this paper, we propose a new change detection using RDF reasoning that only computes a small part of the implied triples using backward chaining strategy. We show that our approach efficiently detects changes through experiments with real-life RDF datasets.

In this paper a web-based real-time education system, which is able to support education through multimedia, is suggested for the expansion of learner's creative ability in the school. This system is designed so that it can support three things: 1) a real time interaction between interaction between instructors and learners, 2) individual learning through such an interaction, and 3) a coercive distribution of display by instructions for preventing the deviation of learners from learning. Also, the system, which UML is applied to, makers efficient interaction possible through the module for the real-time exchange and management of messages even in the multi-user environment. Through this system, not only the simulation by learners can be made for experiments and practices, but also questions and respondence can be supported on the procedure of experiments and the analysis of their results. This system is bulit on constructivism, and aimed at helping the learning progress and knowledge formation of learners.

Purpose. The purpose of this study was to investigate the evidence-based pain management knowledge, performance and Evidence-Based Practice(EBP) attitude of nurses at small-medium sized hospitals. Methods. The sample of this study were 214 nurses. Data were analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation and stepwise multiple regression using SPSS/Win 21.0 Results. Evidence-based pain management knowledge score averaged $3.95{\pm}0.43$, with significant differences depending on clinical experiences. Performance score averaged $3.77{\pm}0.51$. EBP attitude score averaged $3.21{\pm}0.57$, and significant differences were evident depending on hospital division and clinical setting. Evidence-based pain management knowledge and EBP attitude were significant predictors of evidence-based pain management performance. Conclusions. This result indicates that education and training programs to facilitate evidence-based pain management knowledge, performance, and EBP attitude are needed among nurses.

미래 지식정보사회는 컴퓨터, 통신, 방송 등 모든 정보통신 기기가 하나의 네트워크에 연결되는 BcN 기반의 네트워크사회(Broadband Network Society)로 빠르게 진화할 전망이다. BeN은 엑세스망, IP전달망, 제어/서비스망(교환망 IP전환)의 3개 계층을 모두 포함하는 개념이나 엑세스망, IP전달망은 기존과 통일한 IP방식으로 추진 중이어서 IP기반의 제어/서비스망 신규 구축 및 교환망의 IP로의 전환을 협의의 BcN이라 정의 한다. PSTN에서 BcN망으로 전환 시 BeN망의 구성 요소는 소프트스위치, TGW, AGW, SGW, 응용서버, 미디어서버 등이 있다. PSTN망이 BcN망으로 전환시 크게 3단계의 과정을 거친다. 1단계로 2007년 상반기에 전남 목포지역의 지능망 서비스가 불가한 시외교환기가 BcN으로 전환되었다. 전환 후의 IP망을 경유하는 음성호의 트래픽을 측정한 결과는 발생호는 증가하였으며 완료율은0.06% 감소하였지만 관리 기준내의 양호한 수준이었다. 향후 음성호의 통화 품질을 높이기 위해서 품질 측정을 통한 기준 미달 항목을 조치하고 트래픽 측정을 통한 소통율, 완료율 불량 구간에 대한 지속적인 개선 활동을 해야 한다.
