Compared to other countries, cloud computing in Korea is not popular especially in the government sector. One of the reasons for the current not-fully-blossomed situation is partly by early investment in huge government datacenters under Korea's e-government initiative; let alone, there was no strong control tower as well as no enforcing law and ordinances for driving such cloud computing initiative. However, in 2015 March 'Cloud Computing and Privacy Security Act' (hereinafter, Cloud Act) had been passed in the Parliament and from September 2015 Cloud Act was deployed in Korea. In U.S., FedRAMP (Federal Risk Assessment and Management Program) along with Obama Adminstration's 'Cloud First' strategy for U.S. federal institutions is the key momentum for federal cloud computing adoption. In 2015 January, U.S. Congressional Research Service (CRS) has published an extensive monitoring report for cloud computing in U.S. federal institutions. The CRS report which monitored U.S. government cloud computing implementation is indeed a good guideline for Korean government cloud computing services. For this reason, the purpose of the study is to (1) identify important aspects of the enacted Korean Cloud Act, (2) describe recent U.S. federal government cloud computing status, (3) suggest strategy and key strategy factors for facilitating cloud adoption in public organizations reflecting SDLC strategy, wherein.

전략정보시스템의 성공사례로서 항상 제시하고 있는 것이 항공사의 CRS이다. 처음 CRS가 출현했을 때 항공사들은 CRS를 통해서 그렇지 않은 항공사에 비해 상당한 전략적 우위를 지킬 수 있었다. 그러나 현재의 경우 이러한 CRS의 전략적 활용의 예는 그다지 중 요한 의미를 갖지 못할 수 도 있다. 왜냐하면 이제 어느 항공사(서비스제공자)나 어느 여행 사(사용자)의 경우도 이러한 CRS를 활용하지 않는 경우는 없기 때문이다. 그렇다고 해서 CRS가 전략적 가치가 전혀 없다고 단정 지울 수 없다. 만일 특정의 CRS가 다른 CRS와의 차별화 된 기능을 갖고 있다면 그것은 충분한 전략적 가치가 있다고 볼 수 있다. 즉, 보다 다양한 기능, 광범위한 데이터 량, 풍부하게 제공되는 정보 그리고 사용상 편리성 등의 특 성을 가진 CRS는 전략적 의미가 있는 것이다. 본 연구는 이러한 입장에서 CRS의 차별화 된 전략적 특성을 파악하기 위하여 AMADEUS에 대한 사례연구를 수행하였다. 사례를 분석 한 결과 일부 차별적인 기능에 대해서는 전략적 특성을 갖고 있다고 볼 수 있었다.

There had been substantial demand for record management system with which to efficiently control the information circulation processes, involving accumulation of recorded materials, classification of information resources, and users access to them. It converged to a collaboration of Australian federation, and Sydney Records Centre and finally induced Australian Standard Records Management, commonly known as AS 4390. AS 4390 served later as a model for International Standard of Record Management. This paper introduces the current undertaking of Recordkeeping system development in Australia, which stems from the line of AS 4390 by analysing exhibited research approaches. The analysis includes the definition, regime of Recordkeeping system, design and implementing of guidelines of Recordkeeping System and information on metadata projects. It also highlights the necessity for standardization, as is the prime factor in promoting inter-linking of Tabularium on New Southwales State, CRS(Commonwealth Record Series), database system of Canberra National Archives and Australian Government Locator Service. From year 2005, as dictates, any record management system, serving public agency will be required to adapt Professional Archives Management System, which, by far, will enhance the inter-compatibility. In its application, the government need Thesaurus to eliminate possible redundancy in use of terminology and to promote correct usage of words.

This paper proposes a new framework of an autonomous and distributed flexible manufacturing system - Multi Client Robot Groups(MCR) - and describes a stochastic learning scheme applied to managerial problems of the system. The MCR is composed of groups of manufacturing robots, named Client Robots (CRs), which are capable of both versatility and independence in their performances. The MCR is expected to have high performance because the MCR can perform concurrent and corporative processing. However, the system performance is determined by the organizations of the CR groups. Therefore the treatment of the managerial problems and organizations of the system are important problems. In this paper, it is assumed that CR groups being able to processing tasks are selected stochastically based on the strengths of the robot groups. The learning scheme adjusting the strength is introduced to organize the groups in the system and control the each performance of the groups according to the total system performance. Finally, some experimental results of the learning scheme are shown.

Ubiquitous Computing System란, 언제 어디서나 통신 및 컴퓨팅이 가능하고 컴퓨팅 시스템이 상호간에 정보를 공유하고 협력하는 컴퓨팅 시스템이다. 이로써 기존의 컴퓨팅 환경과 같이 사용자와 컴퓨터간의 대화형 상호작용이 아닌 물리적인 환경 상황(Context)등을 시스템이 스스로 인식하고 이를 기반으로 사용자와의 상호 작용을 지원하는 상황인식 기술이 필수적인 요소로 부각되고 있다. Ubiquitous Computing System을 위해 사용자 및 주변 환경의 정보를 감지하는 센서(Sensor) 기술이 필요하다. 하지만 사용자 및 주변 환경으로부터 입력되는 불확실하거나 모호한 상황정보에 대한 표현과 추론에 대한 연구는 부족한 실정이다. 본 논문은 Rule based System을 활용하여 CRS(Context Recognition Switch)라는 새로운 개념을 도입한 Context Aware Architecture를 제시한다. CRS는 유비쿼터스 컴퓨팅 시스템을 위해서는 센서로부터 복합적으로 인지된 사용자 정보 및 주변환경의 정보를 사용자로부터 수동적으로 설정되거나 System의 지속적으로 수집된 정보의 통계 값인 Reference Value와 비교하여, 각 상황에 따른 개별적이고 특화된 서비스를 실행을 하도록 제공한다. 이로써 같은 정보의 입력이 들어와도 그 주변 환경의 상황에 따라 사용자의 필요에 최적화된 실행을 할 수 있다. 마지막으로, Ubiquitous Computing System의 향후 발전 가능성을 예상해고, 본 논문에서 제시한 Context Aware Architecture의 유용성을 짐작해 본다.

In this study we investigate the problem of reducing color change cost at painting operations in an automobile assembly plant. Changing control logic at conveyor junction points prior to the top coat line has been proposed and analyzed using the discrete event simulation model we developed using AutoMod. We also discussed the project which initiated this research as well as the details of painting operations. Simulation analysis showed that the grouping ratio increases from 1.8 to 2.5 if the proposed control logic change is applied to the plant. Contrary to other approaches such as using dedicated equipment for resequencing, our approach has the merit of less investment cost, no need for additional space consumption. We finally note that the grouping ratio can be further increased if our algorithms is implemented as well as CRS (Color Rescheduling Storage) is installed.

Archival description in archives has an important role in document control and reference service. Archives has made an effort to do archival description. But we have some differences and problems about a theory and practical processes comparing with advanced countries. The serious difference in a theory is that a function classification, maintenance of an original order, arrangement of multi-level description are not reflected in practical process. they are arranged in shelves after they are arranged by registration order in a unit of a volume like an arrangement of book. In addition, there are problems in history of agency change or control of index. So these can cause inconvenience for users. For improving, in this study we introduced the meaning and importance of arrangement of description, the situation and problem of arrangement of description in The National Archives, and a description guideline in other foreign countries. The next is an example for ISAD(G). This paper has chapter 8, the chapter 1 is introduction, the chapter 2 is the meaning and importance of arrangement of description, excluding the chapter 8 is conclusion we can say like this from the chapter 3 to the chapter 7. In the chapter 3, we explain GOVT we are using now and description element category in situation and problem of arrangement of description in Archives. In the chapter 4, this is about guideline from Archives in U.S.A, England and Australia. 1. Lifecycle Date Requirement Guide from NARA is introduced and of the description field, the way of the description about just one title element is introduced. 2. This is about the guideline of the description from Public Record Office. That name is National Archives Cataloguing Guidelines Introduction. We are saying "PROCAT" from this guideline and the seven procedure of description. 3. This is about Commomon Record Series from National Archives of Australia. we studied Registration & description procedures for CRS system. In the chapter 5, This is about the example which applied ISAD to. Archives introduce description of documents produced from Appeals Commission in the Ministry of Government Administration. In the chapter 6, 7. These are about the problems we pointed after using ISAD, naming for the document at procedure section in every institution, the lack of description fields category, the sort or classification of the kind or form, the reference or identified number, the absence description rule about the details, function classification, multi-level description, input format, arrangement of book shelf, authority control. The plan for improving are that problems. The best way for arrangement and description in Archives is to examine the standard, guideline, manual from archives in the advanced countries. So we suggested we need many research and study about this in the academic field.
