최근의 프로그램들은 크기가 커지고 기능이 복잡해짐에 따라 모듈화된 구조를 지니고 있다. 프로그램 모듈화는 프로그램의 설계, 제작, 유지보수, 코드의 재사용 부분에서 많은 장점을 가지며 라이브러리라는 개념을 통해 이루어진다. 현재 임베디드 기기를 위한 가상기계인 EVM은 라이브러리 개념의 모듈화를 지원하고 있지 않다. EVM에서 동작하는 프로그램의 모듈화를 도입하기 위해선 라이브러리를 나타내는 아카이브 파일 포맷이 요구되며, 아카이브 파일을 다루기 위한 아카이버와 링커 등의 도구가 필요하다. 본 논문에서는 EVM 프로그램의 모듈화를 위한 아카이브 파일 포맷을 설계하였다. 본 논문의 아카이브 파일 포맷은 유사한 개념의 아카이브 파일 포맷을 분석하여 기본구조를 설계하였으며, EVM 환경에 필요한 특징을 반영하였다. 아카이브 파일 포맷의 설계를 통하여 추후 EVM에서 동작하는 프로그램을 라이브러리화할 수 있는 기반을 만들었다. 이를 바탕으로 프로그램 모듈화를 완성할 것이다.

Pulse oximetry is a well established non-invasive optical technique for monitoring the SpO$_2$ during anaesthesia, recovery and intensive care. Pulse oximeters determine the oxygen saturation level of blood by measuring the light absorption of arterial blood. The sensors consists of red and infrared light sources and photodetectors. In the measurement of the hemoglobin oxygen saturation, conventional method has required the technique of filtering of remove the noise, and of complex signal processing algorithm. So much time have required to signal processing. In this research, we separate AC signal and DC signal in the stage of signal detection. We filter the noise from each signal and convert A/D. We obtain the SpO$_2$ using the DSP algorithm.

We study on the frequency-producer softwearizing method of the already existed detailed-micro-wave tool. In the results, we can attain the more and more miniaturization of the existing tool and the frequency-producer softwearization. The frequency-producer softwearization works are modulizing and each parts are not interdependence, therefore the works are achieved independently. The modulization works are subdivided the drawing up the micro frequency graph, the formation of frequency file, and the frequency productionㆍamplificationㆍtransformation. Each modul is library file, and one modul is organized for the feasibly using another application.

This paper proposes a technical requirements analysis of implementation of multi-trade prefabrication. Recently, there has been a rise in the use of prefabrication to minimize on-site work for time reduction to increase productivity. Prefabrication technique is evolved into multi-trade prefabrication combining other trades from single-trade prefabrication. For implementation of new technique, not only itself but complementary techniques have to be prepared. In this paper, MEP corridor rack, a major item of multi-trade prefabrication, was implemented in the test bed and its process was analyzed to find out technical requirements. As a result, comparatively high level of IT technique was required for efficient use of multi-trade prefabrication in design, lifting and construction phase. In design phase, component level of BIM library was needed for manufacturing; and in lifting phase, BIM-based site logistics process was required. Also in construction phase, laser scanning was implemented for gathering shape and geometry of the wall and slab that were attached to multi-trade prefabrication module.

This paper reports on the development of the analysis program of the piston skirt system, PS-LAP. It is essential to verify the stability of the design and to improve the performance of the system. In order to do that efficiently, it is required that integrated and interactive simulation analysis program. PS-LAP is developed in the base of the object-oriented, capsulation, modulization, OLE(objected linking and embedding) and variational design theory. So it contain the expandability and flexibility of the structure. In addition to that, it is programed to make the convenient user interface by using the visualization programming. It can support the modification of the piston skirt shape, lubrication condition and so on. It is expected to reduce the money and effort for design the piston skirt system.

The design of driver's cab includes the structure of cab frame, the layout of driver's cab equipment and facilities, i.e. driver's desk, seat, windows, floor, interior equipment, cab partition etc. The concept applied to the detail design has to be based on the ergonomics to guarantee the safety, comfort, and easy operation for the driver. In the aspect of manufacture, one more factor 'modulization' has to be considered into the design of sub blocks for cost-down. The design has to be implemented in the space allocated for driver's cab, which space is directly determined by the cab frame, optimized for the layout of driver's cab. The design process and results of the driver's cab for KHST will be described in this paper.

Construction that over 70% of the structure consists of concrete gets bigger and higher gradually and the demand of that is increasing as well. However, it's not easy to supply young and skilled persons on construction site because of social avoidance phenomena about 3D occupation, so it causes serious problems like aging and shortage of technicians. To solve the problems, executives related to the construction field make a management effort in various ways such as construction period shortening, labor productivity improvement and good quality but recently, they have an increasing interest in the necessity of the modularization of the high-rise building and the automation of the engineering development for the strengthening of international competitive power as more active and long-term alternatives. Therefore, this study is to propose the roadmap in order to make lots of efforts in developing construction technologies of high-rise buildings by performing a foundation study, the strategy for 4-step research development, on modularized construction system of concrete structure of high-rise buildings through domestic and foreign preceding research analyses associated with optimal design modularization technique, module factory automation and assembly automation of modularized objects.

As today's home-network market grows related researches had been increased and with different interfaces of these products of course there is lack of compatibility between these systems. So we need some extensionable managing system which integrates and manages these systems. In this paper, we designed framework that integrates and manages network system and also implemented Home Gateway using JMX on Sensor-network environment. It may manage each target with modulization and through the connection interface we make allowance compatibility and extensionability between existing systems. Through this researches, we implemented the Home-network integrated managing system which can manage and monitor with PDA or RDP(remote desktop PC).

Technologies related to sealed-type ultrasonic sensors and driving circuit modules for them are the key elements for intelligent robot industry. Those technologies are believed to yield a drastic enhancement of the performance measuring distances in the intelligent robot systems. Modulization technologies of ultrasonic sensors are expected to develop ASIC and MEMS technologies in the future. The size of domestic market for sealed-type ultrasonic sensor modules is expected to grow to 1 billion and 5.72 billion Won by 2008 and 2012, respectively. Recent interest to service robots and government-driven programs are promoting the rapid growth of the market for the service robots. Successful application of the sealed-type ultrasonic modules to the service robots is expected to replace the conventional photo-sensors in a near future.

in a software development, the design or architecture prior to implementing the software is essential for the success. This paper presents a case that we successfully designed a software architecture of radiation monitoring system (RMS) for HANARO research reactor currently operating in KAERI by applying the quality attribute-driven design method which is modified from the attribute-driven design (ADD) introduced by Bass[1]. The quality attribute-driven design method consists of following procedures: eliciting functionality and quality requirements of system as architecture drivers, selecting tactics to satisfy the drivers, determining architectures based on the tactics, and implementing and validating the architectures. The availability, maintainability, and interchangeability were elicited as duality requirements, hot-standby dual servers and weak-coupled modulization were selected as tactics, and client-server structure and object-oriented data processing structure were determined at architectures for the RMS. The architecture was implemented using Adroit which is a commercial off-the-shelf software tool and was validated based on performing the function-oriented testing. We found that the design method in this paper is an efficient method for a project which has constraints such as low budget and short period of development time. The architecture will be reused for the development of other RMS in KAERI. Further works are necessary to quantitatively evaluate the architecture.
