In order to reduce the cost of software maintenance including software modification, we suggest the object oriented program with checking the version of application program using the Java language and the technique of executing the downloaded application program via network using the application manager. In order to change the traditional scheduler to the application manager we have adopted the Xlet concept in the nuclear fields using the network. In usual Xlet means a Java application that runs on the digital television receiver. The Java TV Application Program Interface(API) defines an application model called the Xlet application lifecycle. Java applications that use this lifecycle model are called Xlets. The Xlet application lifecycle is compatible with the existing application environment and virtual machine technology. The Xlet application lifecycle model defines the dialog(protocol) between an Xlet and its environment

Objective: The aim of this paper is to introduces Hyundai Heavy Industry's ergonomic risk assessment tool, H-OWAS, which is considering work load and frequency compared to the OWAS. Background: As prevalence of work-related musculoskeletal disorders(WMSDs) in ship building industries has been much higher than that in other industries, most of the large scaled corporations have implemented their own prevention program since legislation on the prevention of WMSDs had introduced in 2003. Method: This paper introduces WMSDs prevention program, HEMP(HHI Ergonomics Management Program) which consists of risk assessment, improvement efforts of working environments, medical treatment and training/evaluation and describes how to operate the program. We also describe application of OWAS method considering work load and frequency for risk factor analysis(H-OWAS) and shows methodology for assessing the ergonomic risk factor. And comparison of the assessment results between OWAS and H-OWAS is carried out by statistical analysis. Result: There was statistically significant difference in the assessment results between OWAS and H-OWAS, and regression shows H-OWAS explains the borg's scale of perceived exertion more clearly than OWAS. Conclusion: H-OWAS has been proved more effective tool than OWAS to evaluate ergonomic risk factor under real working condition. Application: H-OWAS can be widely applied to the many other companies when implementing the ergonomics risk assessment.

Application of system engineering should be realized on necessary condition being to propel National Defense R&D Program. But, these necessity is yet not realized easily to many project managers of Defense Acquisition Program Administration(DAPA). As one person of DAPA project manager, system engineering hard to approaches easily by the word itself. There are a lot of difficult sections where should apply how. This paper established DAPA Project Manager and Acquisition Point of Contact of demand Military by main customer (reader), and wished to make understood more easily and approach system engineering application to these. Also, this paper studied project management example that scientific project management techniques of Earned Value Management(EVM) and Cost As an Independent Variable(CAIV) etc. is taken abuzz in DAPA inside by Project management technique that become reform, arc Integrated in system engineering.

Recently as the user request on NoD (News-on-Demand) is largely increasing, there are a lot of researches to fulfill it. However, because of short life-cycle of new video data and periodical change of video data depending on anchor, it is difficult to apply the conventional video storage techniques to NOD applications directly. For this, we design and implement low-level storage manager for efficient storage and retrieval of multimedia data in NOD Services. Our low-level storage manager not only efficiently sotres video stream dat of new video itself, but also handles its index information. It provides an inverted file method for efficient text-based retrieval and an X-tree index structure for high-dimensional feature vectors. In addition, our low-level storage manager provides some application program interfaces (APIs) for storing video objects itself and index information extracted from hierarchial new video and some APIs for retrieving video objects easily by using cursors. Finally, we implement our low-level storage manager based on SHORE (Scalable Heterogeneous Object REpository) storage system by sunig a standard C++ language under UNIX operating system.

복잡한 무결성 제약 조건을 효율적으로 확인하기 위해 제약 조건들을 룰 베이스(rule base)에 저장하고 별도의 룰 관리 시스템과 제약 조건 관리 시스템을 통해 제약 조건을 확인하는 기법이 많은 연구자들에 의해 연구되고 발표되었다. 그러나 제약 조건 관리 시스템이 실행시간에 응용 프로그램을 항상 모니터링하고 있다가 데이타의 수정이 요청될 때마다 개입하여 프로세스를 중단시키고 관련 제약 조건을 확인하는 기존의 방법들은 처리 시간의 지연을 피할 수 없다. 본 논문은 컴파일 시간에 제약 조건 확인 코드를 응용 프로그램에 미리 삽입할 것을 제안한다. 응용 프로그램 자체 내에 제약 조건 확인 코드가 삽입되기 때문에 실행 시간에 다른 시스템의 제어를 받지 않고 직접 제약 조건의 확인 및 데이타베이스의 접근이 가능해져서 처리 시간의 지연을 피할 수 있을 것이다. 이를 위해 어떤 구문이 제약 조건의 확인을 유발하는 지를 추적하였고, 컴파일러가 그러한 구문을 어떻게 전처리 과정에서 검색하는지 그리고 그러한 구문마다 어떻게 해당 제약 조건 확인 코드를 삽입할 수 있는 지를 객체지향1) 데이타베이스 언어인 Objectivity/C++에 대해 gcc의 YACC 코드를 변경함으로써 보여 주었다.Abstract To cope with the complexity of handling integrity constraints, numerous researchers have suggested to use a rule-based system, where integrity constraints are expressed as rules and stored in a rule base. A rule manager and an integrity constraint manager cooperate to check the integrity constraints efficiently. In this approach, however, the integrity constraint manager has to monitor the activity of an application program constantly to catch any database operation. For each database operation, it has to check relevant rules with the help of the rule manager, resulting in considerable delays in database access. We propose to insert the constraints checking code in the application program directly at compile time. With constraints checking code inserted, the application program can check integrity constraints by itself without the intervention of the integrity constraint manager. We investigate what kind of statements require the checking of constraints, show how the compiler can detect those statements, and show how constraints checking code can be inserted into the program, by modifying the GCC YACC file for Objectivity/C++, an object-oriented database programming language.

This study was conducted to evaluate the recognition of HACCP(Hazard Analysis Critical Control Point) concept by the industry foodservice managers in Pusan and the Kyung Nam areas and to suggest a guideline for an effective HACCP education program. A survey was conducted from 133 foodservice managers by using a questionnaire. The results were as follows; 68.0% industry foodservice managers were educated about HACCP concept, 33.8% didn't understand the concept, and only 13.4% understood the concept fully. On the application of HACCP program to the foodservice operation, 15.0% of managers always applied HACCP program, 35.4% often, and 49.6% did not. The reasons for not applying HACCP were the ignorance HACCP implementation method(36.7%), poor facilities of foodservice operations(34.7%), shortage of time(l4.3%), and difficult of HACCP principles(6.1%). The mean score of HACCP knowledge for all manager was 64.1, in which the educated manager showed significantly higher score than noneducated CP(0.01). The ratio of correct answers concerning HACCP was 80.5% for the pre-preparation stage, 60.3% for the receiving and storage stage, 57.0% for the hot and cold holding stage, 54.5% for the facilities sanitation stage, and 46.0% for the preparation stage. The mean score of HACCP knowledge was positively correlated with understanding of HACCP program as well as the application. Also, the implementation of HACCP program was positively correlated with the understanding of HACCP.

The Message-Passing Interface(MPI) is a standard interface for parallel programming environment, based on that application programs run on the processors of a parallel computer. Processor nodes execute processes consisting the program by passing messages to one another. During executing, however, if a fault occurs on a processor node or a process, this will result an inconsistent state, and consequently, the whole program will have to be stopped. To solve this problem, in this paper, we propose a fault-tolerant message passing interface(FT-MPI) by adding a fault manager module to MPI. The proposed FT-MPI does not need any hardware support, and each application program based on MPI can run on the FT-MPI without any modification. The proposed fault tolerance scheme uses the so-called hot-spare process duplication method, and verified by simulations that application programs run despite of any fault with less than 5% overhead on execution time.

In 1977, the Main Street Program(MSP) of the United States was founded by the National Trust for Historic Preservation to revitalize downtowns which suffered major declines in their economy and population. This study analyzed the methodology of MSP such as the Four-Point Approach and the Eight Principles, history of MSP, local program organizational structure, local program budgets and funding, official designation and so on. Three successful cases were discussed the background of an introduction to MSP, implementations, results and revitalization statistics. To be able to apply rural development projects in Korea, this study showed the implications such as the need for a program's ethic and methodology, a strong public-private partnership, a dedicated organization, a full-time professional program manager, a commitment to good design and comprehensive work plan, and an educational program of ongoing training for staff, volunteers and other residents.

We all human beings, should be reached the terminal of life in the world. There is the only difference between that comes suddenly or slowly. Persons who should be come the terminal stage suddenly due to disease, especially, malignancy, are Hospice patients. Hospice work is the work of all of us because anyone, anywhere, whenever can be suffered in terminal stage. The characters of Hospice-care are total care of wholistic human beings, comprehensive total assessment of the life and the team work composed of diverse team-members, for example, doctors, nurses, social workers, physical therapists, psychologists, ministers & volunteers. The care manager of the total care(the coordinator of Hospice care), should be worked systemically and, rationally. The comprehensive assessment concept should be entered to the infra-consultant of terminal care-program. The care manager should be have the ability of comprehensive assessment for terminal patients. It will also help standardization of Hospice, and application of medical insurance and social security.
