인공재해와 자연재해로 인해 발생하는 비정상 하중에 의해 국부손상이 발생된 철골 교량 구조물은 추가적인 2차 붕괴의 위험요소들을 내재하고 있어 신속한 전면 해체가 요구된다. 본 시공 사례는 건설실패와 태풍 및 지진으로 국부손상이 발생된 철골 트러스 구조의 교량의 긴급해체를 위해 발파해체 공법을 적용한 사례이다. 철골 부재의 절단을 위해 성형폭약이 필요하지만 현지에서 수급이 불가능한 상태이기 때문에 장약용기를 직접 제작하고 에멀젼 폭약을 충전하여 만든 성형폭약을 이용하여 발파해체에 적용하였다. 직접 제작한 성형폭약을 이용하여 발파해체한 결과 철골 부재가 정확히 절단되면서 교량의 중앙부가 수직자유낙하하고, 교량의 양 끝단은 지지부를 중심으로 회전낙하 하였다. 또한 존치 구조물 및 주변에 피해가 발생하지 않았으며, 발파 후 파쇄 상태는 매우 양호하였다. 이로 인해 직접 제작한 성형폭약의 절단 성능을 확인할 수 있었으며, 신속하고 안전하게 국부손상이 발생된 구조물을 해체하였다.

The paper proposes a hybrid fire fighting control intelligent system(H-FFIS) using rules and cases to detect fire in Integrated Platform Management System. By far most conventional systems have been based on rule-based system in which expert knowledges are expressed with production rules. It is hard to express the knowledges to detect fire with production rules only. The knowledges of fire detection are often based on previously encountered situations of fires. For improvement of system capability renewing and adding of rules is needed in an already build-up system and such adding and renewing procedures could hinder users from fluent utilization of the system. We design and implement H-FFIS. Compared with rule-based FFIS(Fire Fighting control Intelligent System), H-FFIS extended with case-based reasoning shows that the system proposed here can lead to an improvement in fire detection rate.

최근 국내 기업들의 ERP시스템 도입 사례는 대기업에서 중소기업으로, 제조업중심에서 금융, 서비스, 유통 등의 다양한 산업분야로 그 영역을 확장하고 있다. 또한 SCM(Supply Chain management), CRM(Customer Relationship Management)과 같은 확장ERP 시스템의 도입도 활발히 진행되고 있다. 여러 가지 측면의 ERP시스템의 확장 방향 중에서 산업별 특성에 따른 ERP시스템의 개발은 해당 산업분야의 규모와 중요성의 순서에 따라 그 깊이와 범위가 다르게 이루어 졌으며, 소수 특이한 산업에 대한 솔루션은 미개발 상태인 경우가 많이 있다. ERP 소프트웨어 공급업체들은 주요 산업별로 특징적인 업무 프로세스를 지원하기위해 추가적인 프로그램을 공급하거나 개발 중에 있다. 본 연구는 국내 기업 중 다소 특수한 업무 프로세스를 가지고 있는 OEM(Original Equipment Manufacturing) 형태의 생산방식을 가진 의류 제조, 판매 업체의 ERP도입 사례를 통하여 ERP시스템 유연성의 한계에 대해 검토하여 보고 OEM산업과 의류산업이라는 산업특성에서의 ERP시스템 도입이 어떠한 문제점을 지니고 있는지 조사해 보고자 한다. 본 연구는 이를 위해 OEM산업에 대한 고찰과 의류업종의 업무적 특징을 정리하여 보고 실제 ERP 도입 사례를 통해 발견된 도입 특성 또는 도입시의 문제점과 해결 방안을 제시함으로서 향후 유사 업종의 ERP 시스템 도입 시 유용한 지침(Guideline)을 제공하고자 한다. ERP 도입사례는 SAP R/3를 채택하여 약 9개월간의 도입기간에 나타난 현상들을 기반으로 한다.

Gyeonggi-Do launched the 'Achievement Royalty System(ARS)' in 2011 to promote the refund of excess profits from those firms to local system. The purpose of this study aims to analyze the effect of new royalty system in the public R&D program. From the analysis, commercially successful firms appear to have maintained the same level of innovation incentives even after introduction of ARS. It can be explained that they have given a priority in taking part in the next R&D projects as well as a benefit of systematic supports in technology commercialization and marketing. It is, therefore, fully expected that the policy makers can make ARS an additional funding source in the period of decreasing S&T budget, and have a better chance to gather evidences of successful policy practices to the firms. However, the institutional improvements are required to develop the ARS, which include the incentives of ARS payment and the lower total royalty expectation through the reduction of fix-payment ratio and the exemption of ARS.

In the rapidly changing society since the Fourth Industrial Revolution, the cultivation of convergence talents that can solve complex problems is emerging as an important issue. The purpose of this study is to propose the core competencies required to establish the program learning outcomes of the engineering and education curriculum, which is the accreditation standard of engineering education proposed by ABEEK(Accreditation Board for Engineering Education of Korea). Case study methodology was applied to achieve the purpose of the study. The case of analysis is design and software convergence majors of domestic and foreign universities. The educational objectives and course syllabi were analyzed. As a result of the research, four core competencies to be achieved in the design and software convergence majors were derived in addition to the ten program outcomes presented by ABEEK. New core competencies are convergence ability, creative thinking, entrepreneurship, and design ability. The result of this study is expected to contribute to the development of the evaluation system for the convergence engineering education field.

This study aims to explore preferred title and authorized access points for religious works with sample bibliographic data and authority data. To this end, this study (1) reviewed RDA and recently revised KCR as cataloging rules, (2) investigated the preferred titles and authorized access points of religious works in major national libraries as a case study, and finally (3) suggested a method for constructing preferred titles and authorized access points for religious works in Korean libraries using sample data. The data needed for the study were collected through literature research and case studies, and additional email inquiry with the catalog librarians was conducted. As a result of the study, preferred titles and authorized access points for religious works were proposed in the form of KORMARC bibliographic and authority data.

Riverbed Modeler, which is a commercial packet-level discrete event simulator is used to model, design, and simulate complicated communication protocols and large-scale network. Riverbed Modeler got credit for its reliability in field of network simulation. In the MANET simulation environment using Riverbed Modeler, it is very complicated to add a new routing protocol into existing architecture of routing protocols because it is required lots of modifications of protocol recognition. In this paper, we propose Routing Adding Framework which can reduce errors or mistakes during modifying the existing routing support architecture. Routing Adding Framework is provided as a adapter API for protocol recognition. and it is only minimum modifications for protocol identifiers when a new routing protocol is added to the child process of manet_mgr process which manages routing protocols for IP layer. With Routing Adding Framework, we can reduce less than half modification. Then, we shows an example of implementation of a hybrid routing protocol AntHocNet using Routing Adding Framework, and we verify its design and application of the Routing Adding Framework by obtaining simulation result with similar result given by AntHocNet.

This study aims to examine the capability of organizing local records. Based on literature reviews, this study identified that space can be a useful context of records. Accordingly, it designed a records model on additional space entity. It attempted to organize five sample records based on the space of the port of Busan (Busanhang) using CIDOC CRM (6.0). In conclusion, it presented that a space entity provides relations across other entities. As such, it is possible to propose a defining space entity when designing records model that can support the understanding of records' contexts.

본 연구에서는 국가가뭄정보통계집 내 실제 농경지 피해 사례를 바탕으로 농경지 피해영향지수라는 새로운 개념을 정의하고, 이를 산정하기 위한 방법론을 제안하였다. 먼저, 전국 15개 광역시·도를 대상으로 2018년부터 2021년까지 실제 발생한 가뭄피해 사례들을 심층 분석하고, 대상 지역 내 전체 농경지 면적 대비 농경지 피해 면적의 비율을 대표적인 농업가뭄 피해 인자로 선정하였다. 평년 대비 영농기 강수량 및 저수율을 가뭄영향인자로 고려한 후, 실제 가뭄 발생 당시 인자들 간의 직간접적인 관계를 파악하고, 그 영향 정도를 수치화하여 농경지 피해영향지수를 정의하였다. 추가로, 가뭄피해 발생시기의 농업용수 비상지원 사례에 주목하여 농업용수 비상지원 여부에 따른 가뭄인자의 조건별 농업가뭄 발생확률을 산정하고, 그 결과로부터 대상 지역별 상대위험도 및 농업가뭄 취약 정도를 비교·평가하였다. 본 연구를 통해 산정한 농경지 피해영향지수와 상대위험도는 국내 농업가뭄 취약지역을 선정하는 기준 마련에 도움을 줄 수 있고, 지역별 농업용수 지원의 효율성을 평가하는 요소로써 활용될 수 있을 것으로 기대된다.

Since the aging of coastal structures have been increased, the researches about the reinforcements of the existing aged structures are needed. Especially, the existing armor units placed on rubble mound structures should satisfy the stability against the increased design wave conditions. However the researches about these design problems have not been performed. In this study, the hydraulic model tests to investigate the stability number about the additionally placed armor unit were conducted. The main armor unit is a Tetrapod. The test results showed that the stability number (Kd) for additionally placed armor units(Tetrapod) increased up to maximum 10% comparing with that for 2 layers tetrapod (Kd = 8) within these test conditions with the pattern placing for existing armor layers and the stable armor layer slope for the non overtopping condition.
