군 내 복무 부적응 병사들로 인한 병영사고는 비전투력 손실에 따른 전투력 약화, 대군 신뢰도 저하 등 많은 문제를 유발한다. 군은 복무 부적응 병사들을 사전에 식별하고 사고를 예방하기 위한 심리검사체계로 신인성검사를 개발, 적용하고 있다. 본 논문에서는 사고 우려자를 식별하기 위해 부적응 병사의 행동 패턴과 증상을 온톨로지로 구현하기 위한 온톨로지 설계 프로세스를 제안한다. 온톨로지 설계 프로세스에 따라 설계한 온톨로지의 성능 평가 결과, 적합성 및 효과성이 검증되었다. 온톨로지 설계를 통해 부적응 병사를 식별하기 위한 군 내 객관적인 기준을 제시하고 사고 우려자에 관한 정보를 공유함으로써 사고 예방에 효과적인 역할을 할 것으로 기대된다.

The Ministry of Construction and Transportation (MOCT) has been constructing a nationwide soil information DB since 2000, as basic data for the construction of 'underground geographical information,' a project under the 2nd National Geo-spatial Information System (NGIS) master plan. The inputted soil information includes not only underground conditions such as the layer depth, type, color, and groundwater level, but also engineering information that can be applied to construction work design, such as on the standard penetration test and the compression test. It is difficult to use this information in soil analysis and design, however, because only the test results are currently available. A web-based geo-spatial information system was developed in this study to facilitate the effective application of the soil information database (DB). First, the space information, layer information, and engineering test information were loaded from the soil information DB in real time, and the earth volume, bearing capacity, and settlement were calculated to develop a web client that will evaluate the ground softness and liquefaction. It seems that the soil information DB can be actively applied to the planning and design of construction works using this system.

Purpose: The purpose of this study was to develop a scenario and evaluate the performance of paramedic students in head trauma simulation education. Method: This study selected a refined head trauma scenario that was developed by graduate students during class from september to November, 2010. Evaluation on implementation of head trauma simulation was conducted on seventeen paramedic students divided into four groups during November, 2010. Results: 1. The head trauma scenario was developed according to the patient assessment for approximately 10 minutes. It contained scene size-up, initial assessment and intervention, rapid trauma assessment and intervention, and decision of transfer. 2. The average time turned out to be 9 min and 36 sec after simulation learning. Total mean score in simulation performance was 2.20, the highest score was 2.44 in initial assessment and intervention, and the lowest score was 1.5 in decision of transfer. 3. Confidence mean was high with the score of 1.0. Conclusion: The finding of this study demonstrate that the simulation education can improve problem-solving ability and critical thinking, and increase the confidence in prehospital emergency care; therefore, simulation may be the new effective paramedic education strategy and simulation learning is needed for further development of various scenarios.

The purpose of this research is to apply and evaluate the Water Environmental Education Program Using Streams(WEES) to pre-service teachers. WEES is developed to help the teachers increase their professionalism of incorporating a local environment into their inquiry teaching. The subjects of the study include the juniors of the Environmental Education Major at the Korea National University of Education. For the purpose this study, educational criticism about WEES was performed. The subject students were observed throughout the program application, after which a survey and in-depth interviews were carried out. As a result, the implementation elements and content organization of the WEES were found to be implemented in the application process in a satisfying level. In the content organization of the program, the preliminary preparation, visual assessment, and inquiry planning were organically connected with each other for inquiry purposes. The Intrinsic value of environmental education was also demonstrated in the implementation elements and content organization. Overall, the stream turned out to have a great value of environmental education and a potential as a place and material for environmental education. The great significance of the study can be found in that WEES took into account not only the characteristics of the ENVISION based on the watershed concept, but also the situations of Korea's environmental education and exploration from the perspective of environmental studies.

Manufacturing enterprises have been doing their best endeavors to obtain competitiveness using various methodologies, such as information technology. In order to achieve competitiveness, they are adopting manufacturing execution system (MES). MES is a total management system that manages from the beginning of the production by product order until the quality inspection of the finished product. And MES is an inter-mediator for supplementation of information gap between ERP and inspection machine and equipment. This paper describes on establishment of effective strategy based on BPR methodology and implementation of MES small and medium PCB manufacturing company with multiple-types of products and mixed process flows. And then we proposed evaluation model based on balanced score card (BSC) for considering non-finance elements as well as finance elements. With evaluation model, we analyzed benefits and effects of MES.

As the existing FTAs' implementations are being accelerated, ex-post assessments, such as tariff schedules and agricultural trade analyses results, have been emerging as important national issues for the agricultural sector. Korea-Chile FTA is the first FTA in Korea, and more than ten years have passed since April 2004. It will be necessary to measure the impacts of the agreement on the domestic agricultural industry by analyzing concessions made on traded items of farm products on prices, agricultural trade, and so on. The purpose of this study is to prepare for the request for ex-post assessments on the agricultural sector by trade negotiation procedural law. Additionally, by providing policy direction for agricultural policy segments requiring amendments and supplements through an ex-post assessment, we can more objectively evaluate the conflicting arguments between the agricultural and non-agricultural sectors. Current evaluation methods about ex-post impact assessment of FTA are generally comparison analysis on the change of trade balance before and after FTA implementation. However, this simple comparison analysis cannot be said to pure FTA effects and objective, tightening economic impact assessment of the FTA because of all combined situations such as effects of exchange rates, international macroeconomic changes, climate change, and the occurrence of pests. This research attempts to use dynamic analysis as its ex-post assessment methodology and is expected to contribute to future policy evaluation.

수많은 IoT기기들이 시공간의 제약이 없는 유무선 네트워크 환경으로 연결되어 데이터를 수집 및 전송하는데, 그로 인해 많은 보안상의 취약점이 노출되고 있다, 그러나 IoT 보안은 디바이스와 네트워크의 접근방식이나 구현방식의 차이로 인해 실현가능한 보안표준과 장치인증을 생성하는 것이 쉽지 않다. 디바이스의 보안레벨 강화를 위한 표준 프레임워크의 개선과 적용이 가장 성공적인 보안효과를 거들 수 있는 출발점이라는 것은 분명한 사실이다. 이 연구에서는, IoT 디바이스에 대해 정보보안의 기본 목표인 기밀성, 무결성, 가용성 그리고 접근통제를 확보할 수 있도록 하는 IoT디바이스에 대한 표준화된 보안성 평가기준을 조사하고, 그 개선방안을 연구하고자 한다.

Purpose: This methodological study was done to develop a computerized telephone triage and consultation system for patients discharged with ophthalmic disease in order to provide more efficient practice guidelines for nurses, and evaluate the usability of the system. Methods: Development of the system consisted of six phases: strategic planning, analysis, design, implementation, evaluation, modification, and maintenance. Results: In the strategic planning phase, ophthalmic problems and nursing interventions of triage algorithms and practice guidelines were cross-mapped with the Omaha system. In the analysis phase, users requirements were identified. Then infrastructure including database, nursing knowledge base, and user interface were designed in the implementation phase. Usability and satisfaction of the system presented as very positive. Telephone consultation took about 2 minutes less than time in the previous system. The system was modified based on users' comments during the evaluation phase. Conclusion: This study was the first attempt in Korea to develop computerized triage system to prompt the quality of telephone consultation. It is suggestive that the computerized triage system may improve the quality of nursing.

통신기술이 발전함에 따라 통신망이 아날로그 전송 형태로부터 디지털 전송 형태로 바뀌고 있으며, 궁극적으로는 end-to-end 디지털 통신을 실현하는 종합정보통신망(ISDN)으로 변천하고 있다. 이러한 통신망의 변천에 따라 새로운 망의 설치 및 운용과 더불어 통신의 효율화와 선진화를 달성하기 위한 통화품질의 향상도 중요한 과제로 부각되고 있다. 또한, 새로운 디지털 음성 통신계에서는 통화품질에 영향을 주는 요인들이 기존 아날로그 형태의 음성 통신계와는 다르게 나타나기 때문에 새로운 통화품질의 조건 및 기준을 확립할 필요가 있다. 본 논문에서는 음성통신과 통화품질과의 관계를 설명하고, 디지틀 음성통신계의 통화품질을 설계하기 위한 평가 실험용 디지틀 통화모델 시스템의 설계 및 개발에 대하여 기술한다. 또한, 구현한 모델 시스템의 몇가지 활용을 제안한다.
