Effectiveness analysis of weapon system has been accomplished using engagement-level model alone. However, most previous works are prone to errors due to lack of behavioral information about the weapon systems. In order to overcome these limitations, this paper proposes an interoperation approach between the engagement- and engineering-level models. The proposed approach enables the engagement-level model to be supported by the engineering-level model representing the detailed behavior of weapon systems. Our methodology consider a limited combat situation including operational environments, dynamics and operational errors of weapons, and engagement orders. The paper describes a formalization of the system effectiveness analysis and defines an interface for interoperation between engagement- and engineering-level models. Then, we perform an anti-torpedo combat simulation as a case study.

Modeling and Simulation techniques are useful to construct executable battlefields and forces on computers, and have been utilized to analyze effectiveness of weapon systems in the computerized war environment. However, most weapon simulations so far have exhibited low reusability and extensibility, since they have been developed for specific simulation objectives with different structures and simulation engines. In this paper, we identify requirements for defense modeling and simulation activities and propose a simulation engine to support the identified requirements. We define the software architecture of the proposed engine, in a way to efficiently provide usability, component-based reusability, interoperability, and reuse-based development.

An integrated simulation engine provides tools, services, and standards to support various activities in the entire M&S from modeling and simulation to analysis of the simulation results. Many countries have developed integrated simulation engines to efficiently assist complex M&S activities. However, we do not have domestic simulation engines especially designed for defense M&S, therefore, developing M&S softwares still remains as a hard task with high cost and tine. OpenSIM(Open Simulation engine for Interoperable Models) is an integrated simulation engine and provides tools, services and standard interfaces for weapons analysis. OpenSIM's services are comprised of classes, member functions and data attributes which are commonly used in modeling, simulating and analyzing weapons systems. In this paper, we introduce OpenSIM's services in C++ APIs and illustrate them through an ASM example(Air to Surface Missile).

지금까지의 한국어 자연언어 처리에 기반이 되는 사전 품사 체계에 대한 연구는 형태소 분석, 구문 구조 분석, 그리고 의미 분석 등의 다양한 분야에서 이루어져 왔다. 한국어 자연언어 처리 각 분야는 자체의 고유한 독립성을 가지는데, 이러한 특성은 사전 품사 체계의 다양화를 초래하였으며, 연계성있는 자연언어 처리를 위한 통합 환경 조성을 저해시켜 왔다. 본 논문에서는 한국어 자연언어 처리 전반에 걸친 통합 환경 조성을 위한 범용적인 사전 품사체계의 필요성에 따라 한국어 자연언어 분석의 각 분야에 적합한 사전 품사체계에 대하여 살펴 본 후, 한국어 자연 언어 처리 전반에 사용될 범용적이고 통합적인 기본 사전 품사체계 구축을 위한 방안을 제시한다.

본 연구에서는 인간언어공학에서의 활용을 위해 세종전자사전의 의미부류와 KorLexNoun 1.5의 상위노드 간의 사상을 목표로 전문가의 수작업에 의한 세밀한 사상 방법론(fine-grained mapping method)을 제안한다. 또한 이질적인 두 이종 자원 간의 사상에 있어 각 의미체계의 이질성으로 인해 발생하는 여러 가지 문제점을 살펴보고, 그 해결방안을 제안한다. 본 연구는 세종의미부류체계가 밝히고자 했던 한국어의 의미구조와, Prinston WordNet을 참조로 하여 KorLexNoun에 여전히 영향을 미치고 있는 영어 의미구조를 비교함으로써 공통점과 차이점을 파악할 수 있고, 이를 바탕으로 언어 독립적인 개념체계를 구축하는 데 기여할 수 있다. 또한 향후 KorLex의 용언에 기술되어 있는 문형정보와 세종 전자사전의 용언의 격틀 정보를 통합 구축하여 구문분석에서 이용할 때, 세종 의미부류와 KorLexNoun의 상위노드를 통합 구축함으로써 논항의 일반화된 선택제약규칙의 기술에서 이용될 수 있다. 본 연구에서 제안된 사상방법론은 향후 이종 자원의 자동 사상 연구에서도 크게 기여할 것이다. 아울러 두 이종 자원의 사상을 통해 두 의미체계가 지닌 장점을 극대화하고, 동시에 단점을 상호 보완하여 보다 완전한 언어자원으로써 구문분석이나 의미분석에서 이용될 수 있다.

This study is intended to present methods improving the classification system of KDC architecture engineering fields after comparing and analyzing the academic system of architecture engineering, classification system of KDC, DDC, and LCC, and that of the research field classification system of National Research Foundation of Korea. The results of the analysis have revealed that it is required to improve and correct the KDC 5th edition of architectural engineering including the addition of classification items that reflect the trend of academic development, proper development in the rank classification terms of architectural structure engineering, addition of detailed subjects, selection of proper classification terms, errors of classification symbols and English expression, and omission of correlative indexes in the classification items. This study has proposed improved methods to solve those problems.

A library for the civil engineering field goes on increasing in quantity because of the growth in construction technology and the enlargement in applicable fields of civil engineering. Most of libraries and information centers in construction companies are using Dewey Decimal Classification (DDC) or Korean Decimal Classification (KDC) to classify a library in civil engineering field. It is necessary for the library classification system to be equipped with a more standardized code system, which corresponds to the academical and technical classification for the civil engineering works. This study analyzes the defects of existing classification systems, and then suggests a new classes and divisions classification system, which facilitates to link academic information with technical data, for the civil engineering field. The proposed system is expected to make practical application of information classification system in the construc ion industry and to be applied for the revised edition of KDC.

This study aimed to seek the ways of improving program outcomes assessment systems for engineering education accreditation of South Korea through performing comparative analysis on those of the United States. Case-study research method was implemented to achieve the research goal. Five university programs, which have been well recognized as good practices in engineering education accreditation in the United States, were selected and analyzed. In addition, those of three universities in South Korea were chosen for comparative analysis, which were reformed by university affiliated Engineering Education Innovative Centers. The analysis results indicated that there were differences in each program's program outcomes, assessment level of program outcomes, evaluation methods on program outcomes achievement, and analysis and improvement records. It was drawn up that the evaluation methods on program outcomes achievement should be paid full attention. For better program outcomes assessment system, however, the followings are in more attention. Firstly, to establish program outcomes reflecting program goal. Secondly, to set up the detailed plans for analysis and quality improvement on program outcomes. Thirdly, to keep continuing efforts on curriculum update.
