공동작업 환경의 일관성 제어를 위한 즉시 변경 통보 방법
오암석 울산과학대학 1996 연구논문집 Vol.22 No.-
소프트웨어 시스템은 여러 작업 공간으로 부터 공동 작업에 의해 개발된다. 이 때 서로 다른 작업 공간의 모듈간에는 다양한 종속적 관련성이 존재하며 각 작업 공간에서 이러한 종속적 관련성이 있는 모듈을 각각 독립적으로 변경할 때 이에 따른 일관성 제어 문제가 해결되어야 한다. 아울러 여러 작업공간간 동일 모듈을 동시에 변경할 때 발생하는 conflict문제도 고려되어야 한다. 이 논문은 클라이언트-서버 환경에서 다양한 관련성을 가지는 여러 모듈들로 구성된 소프트웨어 시스템 개발 환경에서 공동 작업시 작업 공간간의 관련 모듈 변경에 관한 일관성 제어 방법을 제시한다. 이를 위해 다운로드시 발생되는 다양한 동적 관련성을 자동 유도 생성하고 이를 기반으로하여 작업 공간으로 부터 변경이 발생할 때 변경 내용과 동적 관련성에 따라 해당 규칙을 호출,실행하므로서 관련된 작업 공간으로 변경 내용을 즉시 통보하는 방법으로 일관성을 제어한다. The software system is developed by a cooperative work in the several workspaces. At this time, there exist various dependent relationships among modules of the several workspaces. The problem of consistency control should be resolved, when these dependent modules are independently updated from each workspace. The problem of a conflict by multiple updates should be also resolved clearly, if a module is simultaneously updated from several workspaces. This paper presents a method for consistency control on updates of related modules among workspaces, when the software system is cooperatively developed. The development environment of the software system is the client-server environments composed of many modules with various relationships. Thus, in this paper, various dynamic dependencies automatically are derived and generated by the system called the Consistency Manager, when a module is downloaded into a workspace. Accordingly, if an update is occurred from a workspace, the update can be immediately notified to related workspaces through the execution of a rule based on an updated content and the dynamic dependencies.

A study on the natural convection inside an L-shaped enclosure of which left wall is maintained at T_C and right wall and part of the bottom are T-H has been performed numeriacally for aspect ratio A=1, geometrically different five cases and for Ra=1×10³∼1×10^5. As the L-shape of the enclosure goes thinner vertically and horizontally like case 5, the mean Nusselt number at the left cold wall becomes smaller for same Ra, and there is little influence of the increase of Ra on mean Nusselt number.

Nowadays, the broadening of users of Internet to general public and the generalization of information sharing through the Web, more importance is given to Internet which may increase the official efficiency in the enterprise and provides the instant service of necessary information through the Web. However, though some cases of Intranet construction in some companies have proven the efficiency of Intranet, most companies are still reluctant to introduction of Intranet because of the cost and security problem. Therefore, when more systematic security system is designed, the data and users of Internet are managed in real time, and the differentiating service for the users is developed easily on the Web, it will be in short time to establish the network of Intranet among enterprise. In this paper, we propose an intranet solution for the small-to-middle sized companies, SIGMA, in which every management process is possible on the Web and the separate information service for each group, and for each person is provided. And, to differentiate our solution from existing ones, we provides the manager interface by which the management on the Web is possible and the constructional plan of Intranet solution for the enterprise in low price.

In this paper, we present the method that improve alarm security system using the electronic circuits added the emergency lamp by our proposed Algorithms. In conventional method the emergency lamp of warning & alarm system didn't work perfectly its performance because of battery with short life. For improving this problem we, using Periphera1 Interface Controller IC, designed the circuit added the emergency Samp for an warning & alarm system and for prevention against stopping the electric current, and compared our proposed method with conventional method.<br/> By designing the circuit to stop up over charge we can extend life of battery, use for a stoppage of electric current in emergency and according to the lightness around. Therefore we are very convenient and profitable in our life.<br/> In the future we will study the method to lower the cost of architecture for practical utilization.
Research on Efficient Through Convergence of IoT Interaction Device and Opened Platform
Am-Suk Oh 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.5
In this paper, we propose a design configuration of a unified remote controller under IoT environment using IFTTT services. This unified controller approach is necessary to avoid the limited functionalities of smart phone App approaches without unified control. The proposed system design can be implemented with one-chip IoT interaction module that can be used in wearable devices.
A Study on HL7 Standard Message for Healthcare System Based on ISO/IEEE 11073
Am-Suk Oh 보안공학연구지원센터 2015 International Journal of Smart Home Vol.9 No.6
We studied the standard of HL7 message for healthcare system which can support diagnosis for healthcare provider and user. We studied the connection of standard medical devices, i.e., continua health alliance under the Android 4.x Bluetooth HDP (Health Device Profile) environments based on ISO/IEEE 11073 which is standard of information exchange among health device agent and service. And also we studied smart healthcare system using smart phone depending upon current trend. This system was studied on the environment of ISO/IEEE 11073 and HL7 standard.
A Study on Design of Health Device for U-Health System
Am-Suk Oh 보안공학연구지원센터 2015 International Journal of Bio-Science and Bio-Techn Vol.7 No.2
U-health system supports health care services of prevention, diagnosis, medical treatment, post health management and currently various medical service systems such as remote diagnosis, emergency medical treatment, private living body monitoring are developed and serviced. There are network compatibility problems among the u-Health devices as their different protocols and software, which are manufactured depending on the characteristics of companies. The utilization of medical information thru hospitals and medical agencies is needed in this society. Thus, in this thesis, we study the design of health devices to analyze and adjust the U-health system.
