  • 상지대학교 #낙석 및 산사태 방재연구단#에서는 #건설교통부 지역기술혁신사업#의 일환으로 사계절 낙석과 산사태 위험에 노출되어 있는 강원지역의 주요 도로 사면에 대한 재해를 저감하기 위하여 통합 사면관리기술, 광역산사태 저감기술 및 사면 안정성중대기술을 개발하고 있다. 본 논문은 강원지역의 최근 5년간 시공된 주요 사면별 178종의 애트리뷰트들의 정보를 Database화하고 이를 활용하여 시공 예정인 특정 사면과 환경조건이 유사한 사면에 적용하였던 공법들과 이에 따른 유지보수 내역과 안정성 등의 정보를 제공하는 사면정보 검색시스템의 설계와 구현에 관한 것이다. 검색의 효율성을 위해 18종의 중요 애트리뷰트들을 선정하고, 이들을 선택형과 기재형으로 분류한 후, 공법들간의 유사도(일치도)를 측정하는 방안을 도입하였다.

  • This study was aimed at the detection of 40 semi-volatile organic base/neutral compounds from soil among 129 priority pollutants listed by EPA. Two extraction procedures, sonication extraction and Soxhlet extraction, were studied as a extraction and concentration method for priority pollutants in soil. Extracts were analyted by GC/MS-SIM(selected ion monitoring). The analytical methods were tested by standard compounds spiked into blank soil. Accuracy and precision of the methods were measured by calculation of mean recovery and mean relative standard deviation. And the method detection limits were estimated.

  • The simultaneous analysis of 11 semi-volatile organic acid compound which are listed as priority pollutants by EPA, were performed by GC/MS-SIM(selected ion monitoring). Two extraction procedures, sonication extraction and Soxhlet extraction, were studied as an extraction and concentration method for priority pollutants in soil. Accurecy and precision of the methods were measured by the calculation of mean recovery, mean relative standard deviation, and method detection limit. Finally, limitations and prospects were discussed.

  • The purpose of this study was to investigate the nutritional composition of native and hybrid pork in Korea. Three different parts (ham, loin and belly) of both native and hybrid pork were used. The results were as follows The moisture content from Korean native pork was about 60.28%, while that from the loin of hybrid one was 69% and decreased in the order of him, loin, and belly The highest protein content of 19.71% was found in Korean native pork loin, and Korean native pork ham had a significant amount of protein of 17.80% and hybrid one had 13.14% (p< .05). The highest crude lipid, 34.44%, was found in hybrid pork belly, Korean native pork ham had a significant amount of 5.43% and hybrid pork had 2.33% (p< .05). The highest carbohydrate content of 13.28% was found in the Korean native pork belly. The amount of ash was in the order of loin, ham and belly in Korean native pork. Among the minerals, K was found the most in Korean native pork ham (654.82mg) and hybrid one (747. 35mg) (p< .05). Fe was higher in the Korean native pork ham (23.03mg), loin (15.86mg) and belly (10.80mg) compared to the hybrid pork ham (19.04mg), loin (11.63mg) and belly (7.61mg). That was significant ham, loin(p< .01) and belly(p< .05). The main free amino acids of the native and the hybrid pork in Korea were alanine, aspartic acid and lysine. While the cholesterol content was found to be high in the order of ham, belly, and loin in the Korean native pork, in the order of belly, fresh ham and loin in the hybrid pork. The cholesterol contents in ham were significantly different between the Korean native pork(789.32$\mu\textrm{g}$) and the hybrid pork (538.84$\mu\textrm{g}$) (p< .01).

  • 최근들어 이기종의 컴퓨터들이 네트웍으로 연결되고, 분산처리화 되면서 다양한 분산기술들이 연구되고 있다. 이런 기술들의 일종으로 이동에이전트 시스템에 대한 개념이 만들어졌으며, 최근에는 이동에이전트 시스템에 대한 연구와 개발이 증가하고 있다. 하지만 에이전트에게 많은 기능을 부여할 경우 에이전트 모듈자체가 커져서 네트웍 트래픽을 증가시키는 단점이 있다. 본 논문에서는 CORBA 객체와 에이전트간의 통신을 가능하게 하여 에이전트 기능의 일부를 CORBA 객체로 구현하므로써 에이전트 모듈 크기의 문제점을 해결하였다. 또한 호스트에서 서비스객체가 없는 경우 에이전트의 이동경로를 토대로 서비스 객체의 위치를 확인하여 이동시키는 것을 제안한다.

  • Tooling is now considered as a major limiting resource for highly automated manufacturing systems to be operated unattendedly. In this paper, various issues in tooling are introduced and discussed. The importance of appropriate selection of tooling strategies is discussed and simulation experiments are performed to see how the tooling strategies affect the system performance in automated manufacturing systems. This paper also presents a tool management system developed in Korea Institute of Machinery and Materials.
