An air pollutant emission inventory system for the input preparations of photochemical dispersion model was developed. Using the system, anthropogenic emissions as well as biogenic emissions in the Seoul metropolitan area were calculated. Anthropogenic emission by fuel combustion using regional cosumption data, and the laundries and so forth was estimated. The biogenic emission was estimated based upon meteorological data and the distribution of land use type in the study area. The anthropogenic emission of pollutants was highest in Seoul, and the second highest in Inchon. TSP and $SO_2$ were found large quantities during the winter due to increased consumption of heating oil. NOx and THC were emitted without seasonal variation. Among biogenic emissions, PAR was very common while NO was the least common. PAR, OLE, and ALD2 were emitted in large volumes in coniferous forest areas, while ISOP was emitted in deciduous forest areas. Generally, most biogenic emissions increased during daytime, and peaked between oen and two o'clock. Because of strong solar radiation, emission during the summer was high. Biogenic NO emissions were found to be lower compared to anthropogenic emissons, and other VOC was indicated relatively high. In the study area, among biogenic emissions PAR was found to be 3 times, OLE 8 times,and ALD2 12 times more common than among anthropogenic emissions.

GPS/GIS Related Information Technology evolves drastically and a great quantity of spatial information is available to users who require highly qualitative spatial information services. Hence the development of GIS tools that can improve position accuracy and maintenance efficiency is required. To meet various requirements from users. we developed a GPS data processing component based on OLE/COM by utilizing GDK which is a unique domestic GIS product. Also we developed an application package that includes the GPS data processing component to implement GPS into GIS. The development of GPS data processing component will contribute toward the expansion of component-wise GIS softwares.

누구나 한번쯤은 CORBA, OLE, COM/DCOM, SOM, DCE와 같은 분산 객체 기술의 핵심이 되는 용어들을 들어 봤을 것이다. 이러한 분산 객체 기술은 현재 우리가 접하고 있는 컴퓨팅 세계에서 가장 중요한 핵심 기술이라 해도 과언이 아니다. 본 고에서는 이들 중에 가장 대중의 관심과 지지를 받고 있는 CORBA의 객체 지향 기술을 살펴보고, 그를 구현한 상용 제품들의 기능을 비교해 봄으로써, 향후 분산 개발 환경을 이용한 시스템 개발에 필요한 사항을 알아보고자 한다.

Based on two real and invertible $d{\times}d$ matrices Band C such that the norm $||C^T\;B||$ is sufficiently small, we provide a construction of tight Gabor frames $\{E_{Bm}T_{Cn}g\}_{m,n{\in}{\mathbb{Z}^d}$ with explicitly given and compactly supported generators. The generators can be chosen with arbitrary polynomial decay in the frequency domain.

This paper presents a method for automatic generating of check sheet to measure deep-drawn sheet metal. By using polyhedral model of CAD, the proposed procedure calculates measuring points automatically. The results of measure are exported to MS-Excel. The proposed method is implemented by API functions and C language using SPEED plus CAD/CAM system and MS-Window OLE.

산업생산 공정의 많은 과정이 종래에는 주로 기술자와 운전자와 조업지식과 경험에 의존하고 있다. 그러나 전산화를 통해서 이러한 기술을 체계적으로 축적할 수 있게 되었지만, 공정상의 모니터링 시스템은 잦은 공정의 변경으로 재구성에는 상당한 노력이 들어간다.물론, 객체 지향언어를 이용하면 좀더 노력을 줄이고 용이하게 할 수는 있다. 그러나, 재 컴파일과 재구성에 시간이 필요이상으로 들어간다. 본 논문은 객체지향기술의 한 형태인 OLE 활용기술 중 OCX를 이용하여 구성요소의 변경측면의 유지 보수에서 상당한 효과서을 확보하였다. 이로 인한 생산 산업에 경쟁력을 확보하도록 산업생산공정의 모니터링 시스템 개발과 구축을 목표로 한다.

사회 경제적으로 지리 정보에 대한 관심이 커지고 있으며 인터넷 기술의 보급으로 일반인들도 지리 정보를 쉽게 접근할 수 있게 되었다. OpenGIS는 지리 정보를 표현하고 공유하는데 필요한 데이터 모델 및 상호 연동을 위한 표준이며 CORBA, OLE/COM, SQL 세가지 환경에 대해 구현 명세가 있다. 본 논문은 ODBMS를 저장 시스템으로써 사용하고 CORBA를 분산객체기술로 활용하여 OpenGIS SFCORBA(Simple Features Specification for CORBA) 인터페이스를 구현하는 방법을 설명한다. 특히 ODBMS와 SFCORBA 사이의 인터페이스를 변환하는 Wrapper의 역할, 자동 생성 방법, 구현 등을 중심으로 기술한다.

This paper proposes a strategic model of linkage between productivity metrics and financial accounting metrics to properly evaluate the financial effect of TPM activities and the business performance. This linkage strategy provides a connection tool for clear communication between factory-level and headquarters that the metrics proposed by this paper ultimately improves a quality of support from the management by receiving the factors required for productivity activities in the practical field. This factor includes such as equipment, raw materials and labors. Here, we propose that chain reaction models using break down structure of productivity metrics and financial metrics enhance the knowledge sharing of KPI (Key Performance Indicator) which generally tend to create oversimplified communication between management in headquarters and employees in the practical fields. The productivity metrics include OEE(Overall Equipment Effectiveness) of TPM (Total Productive Maintenance), OLE (Overall Labor Effectiveness) of PAC(Performance and Analysis and Control) activities, and OYE (Overall Yield Effectiveness) of TMM(Total Material Management) activities. The financial accounting metrics include ROE(Return on Equity), ROA(Return on Asset), and AVR(Added-Value Rate). The suggested chain reaction model selects the financial metrics as initial stage and branch down until final stage of productivity metrics. When demand exceeds supply, an ideal speed rate, the lean OEE strategy can be initially applied to reduce the gap between the demand and supply, then apply variable costing to estimate correct amount of operating profit. In addition, the paper presents a new type of model for linkage between financial accounting metrics including CAPEX(Capital Expenditure), OPEX(Operating Expenditure), EVA(Economic Added Value), DCL(Degree of Combined Leverage), and TPM productivity activities including AM(Autonomous Maintenance), PM(Preventive Maintenance), MP(Maintenance Prevention) and QM(Quality Maintenance). In order to support the evidence of proposed linkage strategy, a case analysis on 52 projects from national TPM contest from 2011 to 2012 is analyzed. The case presents the classification of CAPEX and OPEX activities from TPM, and proposes the correct implementation of financial effect for TPM projects.
