In cloud environment, enterprises use a number of systems which are not interconnected and save master information in a distributed way in each of them. Master information which is not managed is incorrect and discord each other so that lowers efficiency of business process and disables optimum decision making. It is necessary to do high-qualified management of master information to operate efficient and errorless business process. This paper suggests TMDM as a solution to solve heterogeneous problems occurred between interconnected master information in cloud environment and to manage business process in an efficient method. TMDM is an information storage that is suggested to solve mutual discord problems between master information using Topic Maps that considers correlation between data. Topic Maps can be connected by association between topics in order to access through a topic to all related knowledge information which is described by the topic. This also can be applied to master information between legacy systems within cloud.

In this paper, we implemented a high-performence memory controller which can accommodate processing blocks(multiple masters) in SoC for video signal processing. The memory controller is arbitrated by the internal arbiter which receives request signals from masters and sends grant and data signals to masters. The designed memory controller consists of Master Selector, Mster Arbiter, Memory Signal Generator, Command Decoder, and memory Signal Generator. It was designed using VHDL, and verified using the memory model of SAMSING Inc. For FPGA synthesis and verification, Quartus II of ATERA Inc. was used. The target device is Cyclone II. For simulation, ModelSim of Cadence Inc was used. Since the designed H/W can be stably operated in 174.28MHz, it satisfies the specification of SDRAM technology.

The dynamic modulus of hot mix asphalt is one of the important indicators to evaluate the durability and performance of asphalt pavement. In resent, the dynamic modulus is suggested by a key property of asphalt pavement design and analysis in AASHTO 2002 Design Guide and Korean Pavement Research Project(KPRP). Master curve from laboratory test results should be needed for pavement design and analysis. The process to get the master curve is standardized. But, there are some setup and testing error at low temperature(-$10^{\circ}C$) and high temperature ($55^{\circ}C$). In this paper, a simplified process which is used 3 testing temperatures (5, 21, 40) is adopted to get the master curve. Comparison was carried out for standard process and simplified process. The suggested process can be used to get the master curve of asphalt pavement, even though some difference was shown at high temperature.

With the spread of technology in the 4th Industrial Revolution, the defense industry in South Korea is getting developed into an industrial structure in which high-tech technologies are concentrated. As the importance of defense technology has gradually increased, the government has enacted the Defense Technology Security Act and required to build a protection system for institutions that possess or manage defense technology. In order for the target institution to introduce a protection system, it is necessary to identify the defense technologies that are protected and to ensure systematic data management. In order to cope with this, we derived master data items for data management and analyzed the implementation types of defense technology master data system suitable for the defense industry environments. The derived method identified the defense technology master data, such as primary and secondary master data, and through AHP analysis, Co-existence type was suitable as the target model for the master data management system. We expect that stronger defense technology security policy will be implemented through the defense technology MDM system.

전기공사협회가 추진하는 전기설비시공의 '마스터 스펙 프로젝트'는 민간에 의한 '표준 제정'의 사례에 해당한다. 이 글에서는 표준 제정의 환경 및 요소에 따라 마스터 스펙의 특성을 분석한다. 분석 결과, 마스터 스펙의 제정과정은 산업협회(association) 중심의 거버넌스 형태를 띠는 것으로 나타났으며, 이 경우는 특정 산업 부문 내에서 이루어지는 합의 방식이 표준 제정의 특징으로 보인다. 한편, 우리나라에서 산업에 대한 규제나 지원이 정부 주도로 이루어진다는 점, 산업분류에서 전기공사업의 위치가 이중적이라는 점, 또 전기공사 산업 부문이 분산적 산업구조를 띠고 있다는 점 등이 마스터 스펙의 제정에 영향을 미치는 것으로 분석되었다. 그러므로 전기공사협회는 마스터 스펙을 제정하면서 수직적 수평적 전기공사업 관련 조직들을 관리하면서 합의형성을 추진하고 제정 과정을 관리해야 할 것이다.

서울대학병원의 마스터플랜 재구성에 대한 프로젝트로서 기존의 환경에 대한 조사와 분석 그리고 외국사례와의 비교를 통해 앞으로 서울대학병원이 나아가야 할 목표 및 방향을 단기(1-2년), 중기(2-5년), 장기(10년 이상)계획으로 나누어 각 단계별 항목들을 분석, 구체화하였다. 단계계획에서는 응급실의 확장과 어린이 병원증축에 대한 내용을 제시하였고, 중기계획에서는 외래진료센타(ambulatory care center)에 대한 공간구성을 통하여 기존 마스터플랜이 나아가야 할 방향을 제시하였다. 장기계획에서는 어린이 병원의 이전, 캠퍼스 기능구획을 연구, 교육, 병원으로의 분류, 공급시설의 개선과정을 제시하였다. 이 연구를 통하여, 한국의 병원시장에 대한 경향을 다음과 같이 분석할 수 있었다. 1) 증축공간이 부족한 도심에 밀집한 한국병원의 경우, 리노베이션을 통한 마스터플랜은 다양한 시설물을 개선, 관리, 통합할 수 있는 방법이다. 2) 편리성, 환자의 프라이버시, 전문성, 방문자 오락시설, 통합적인 치료환경의 구축이다. 3) 예방 의약품의 증가, 건강센타, 건강중심의 프로그램, 확장된 진료시설 등 건강유지분야의 개발이다. 마스터 플랜은 계속 진행되는 과정의 일부분이며, 변화하는 조건 속에서 적용되어, 수정되어져야 할 것이다.

The authors investigated demographic characteristics, role, job satisfaction, and necessity of education of the shop masters and sale persons who worked at clothing shops in department stores. Shop masters were older, had worked longer, and received more salary than sales persons. Role difference was not clear, but shop masters worked more in display, suggestion of merchandise change and order, and management of shop. Shop masters had more pride in job than sales persons, and both of them wanted more education about job.

H-Bridge Multi-Level (HBML) 고압인버터는 저압의 반도체 소자를 사용하는 단상 H-Bridge 인버터로 구성 된 셀을 직렬로 연결함으로써 정현파에 가까운 고전압을 얻을 수 있고, 입 출력 고조파가 낮아서 필터가 필요 없는 토폴로지로 산업분야에서 사용이 확대되고 있다. 본 논문은 HBML 고압인버터의 마스터 제어기와 셀 제어기의 통신 하드웨어를 병렬로 구성하여서 하나의 전압지령 값과 Angle 값으로 셀에서 PWM을 구현 할 수 있는 분산제어 방식을 제안한다. 이 방식에서 셀 제어기가 전압, 전류, 주파수, 보호기능, 통신감시 정보 등 셀 제어의 대부분을 담당함으로써 마스터 제어기의 부담을 줄이고, 따라서 신호선의 개수를 줄일 수 있다. 또 통신하드웨어의 종단에 마스터 제어기를 연결만 하면 마스터제어기의 2중화가 가능하므로 사용하고 있던 마스터 제어기의 고장 발생 시에 대체하여 사용할 수 있으므로 시스템의 안정성 향상에 도움을 준다. 선간전압 33레벨로 구성된 HBML 고압인버터 시험을 통해 제안된 방식의 타당성과 신뢰성을 검증한다.
