최근 생체인식 산업은 금융, 컴퓨터 보안, 통신 부분, 출입국 관리, 의료, 사회복지, 경찰법조, 군사보안 등의 여러 분야에 활용되어 실제 적용되고 있다. 생체인식 분야는 사용되는 생체인식 특징들과 실제 운용되는 환경이 매우 다양하기 때문에 생체인식 소프트웨어의 시험과 평가에 대한 객관적 평가가 매우 중요하다 이를 위해서 생체인식 소프트웨어의 특성을 고려한 평가모듈(Evaluation Module)이 필요하고, 이를 토대로 시험규격서, 품질 검사표, 테스트케이스, 시험결과서가 도출되어야 한다. 또한, XML(extensible Markup Language)은 네트워크와 어플리케이션간 교환되어지는 정보를 명세하기 위한 언어로 데이터 교환과 공유에 대한 표준으로 그 응용 영역이 확장되어 적용되고 있다. 본 논문에서는 ISO/IEC 9126과 ISO/IEC 12119를 도입하여 생체인식 소프트웨어의 품질특성을 분석하였으며, 시험과 평가를 위해 선정된 평가모듈의 XML 스키마에 사용자 요구를 따른 여러 문서 스타일을 적용함으로써 작업효율의 진행성을 보장할 수 있었다.

It is possible to implement high quality system which coincided with embedded system purchaser's requirements by quality test. The concrete quality test system applicable within our country for embedded software was not constructed yet. Recently, various embedded systems are developed, but they have many problems such as recall by defect. In this paper, we developed evaluation modules and quality test fables which can implement duality test based on ISO/IEC 12119 for embedded software evaluation.

IT 조직의 활동에 대한 성과 평가는 과거 재무적인 평가방법이 주를 이루었으나 최근에는 정보시스템 기능과 활동 주체가 다양해짐에 따라 재무적인 접근방법과 함께 새로운 평가 방법 및 기준에 대한 연구가 진행되고 있다. 특히 균형 성과표 (Balanced Scorecard: BSC) 개념을 IT 활동 평가에 적용한 IT-BSC에 대한 연구도 이루어지고 있다. 그러나 정보시스템과 기업전략과의 관계에 대한 규명이나, 다양한 IT 성과측정지표들간의 연계성을 측정하는 연구는 이루어지고 있지 않은 실정이다. 이에 본 본 연구에서는 IT 조직의 성과평가를 위한 핵심성공요인(CSF)과 핵심성과지표(KPI)를 도출하고, 도출된 지표간의 인과관계를 검증하고자 한다. 본 연구의 결과로 도출된 영역과 지표들은 각 산업영역에서 IT 조직의 성과를 측정할 때 참고하고 적용할 수 있는 효과적인 지침으로 활용될 수 있다는 데에 연구의 의미를 둘 수 있다.

The purpose of this study has been carried to develop a criterion for the selection of evaluation factors on Forest Carbon Cycle Community(F.C.C.C) based on the result of survey of 96 participants who were operation managers on mountain eco village(31), relevant experts(33), and officers of local government(32). For analysis of the results of survey, DHP(Delphi Hierarchy Process) method was used which is a combination of Delphi method and AHP(Analytic Hierarchy Process) method. The key factors on selection of a suitable area to launch F.C.C.C. project of Korea Forest Service was selected under three hierarchical classes. Class 1 comprises 3 indices(Physical resource index, Human resource index, Vision index), and Class 2 which contains 10 indices (Existing resource, Surroundings resource, Forest biomass resource, Humanities Social quality, Local resident participation, Leader's ability, External support, Planning of operation, Capability of operation, and Effect of operation). Class 3 is sub-level class of class which possess 38 indices. From the results of analysis, Consistency Index(C.I) of each index in the 3 classes was used as evaluation factor. In Class 1, index 'human resources' showed highest Consistency Index(0.454). In Class 2, index 'forest biomass resources' was the highest Consistency Index(0.376) in 'physical resources' of Class 1, index 'leader's ability' was the highest Consistency Index(0.326) in 'human resources' of Class 1, and index 'planning of operation' was the highest Consistency Index(0.346) in 'vision' of Class 1. In Class 3, relative importance of 38 index including 'Joint ownership land security(C.I.-0.266)' was evaluated. Based on the result of this study, a criterion for the selection of evaluation factors for F.C.C.C was developed and the evaluation criterion is expected to be use to select of a suitable area to launch F.C.C.C. project since 2011.

The agricultural area was classified into dry and paddy fields in this study using the near-infrared band of Landsat TM to extract land cover classes that need to the application of Expected Mean Concentration (EMC) in nonpoint source works. The accuracy of image classification of the land cover map from Landsat TM image showed 83.61% and 78.41% respectively by comparing with the large and middle scale land cover map of Ministry of Environment. As the result of Soil Conservation Service (SCS) Curve Number (CN) using the land cover map from image classification, Dongbok dam and Dongbok stream basin were analyzed high. Also Geymbaek water-gage and Bosunggang upstream basin showed high in the analysis of EMC of BOD, TN, TP by basin. And also Geymbaek water-gage and Bosunggang upstream basin showed high in the analysis of non-point source through coupling with direct runoff. Therefore these basins were selected with the main area for the management of nonpoint source.

Several emergy researches have been carried out to estimate the value of marine ecosystem services in Korea over the last decade. Their results cannot be compared mainly due to inconsistency in emergy-money ratios used to convert emergy unit into monetary unit. This study aimed at providing a standardized format for the emergy evaluation of the Korean economy and environment for different emergy evaluations to be compatible. Even though the area of the continental shelf increased in this study compared to those of previous studies, areaweighted average tidal range for the entire continental shelf of Korea resulted in smaller tidal range, decreasing the final emergy input from tide. However, emergy inputs from nonrenewable resources and purchased goods and services increased with new categorization and use of more detailed data, combined with updated unit emergy values. This led to higher emergy-money ratio for the Korean economy, indicating that previous emergy valuations might have overestimated the contributions of marine ecosystem to the real wealth of the Korean society. The base year for gross domestic product used in the emergy evaluation needs to be clearly indicated due to its impact on the calculation of the emergy-money ratio. A standardized emergy table for the Korean economy will contribute to ensuring consistency among future emergy researches on the valuation of marine ecosystem services.

Numerical values of thermodynamic properties such as temperature, pressure, dryness, volume, enthalpy and entropy are required in numerical analysis on evaluating the thermal performance. But the steam table itself cannot be used without modelling. From this point of view the neural network with function approximation characteristics can be an alternative. the multi-layer neural networks were made for saturated vapor region and superheated vapor region separately. For saturated vapor region the neural network consists of one input layer with 1 node, two hidden layers with 10 and 20 nodes each and one output layer with 7 nodes. For superheated vapor region it consists of one input layer with 2 nodes, two hidden layers with 15 and 25 nodes each and one output layer with 3 nodes. The proposed model gives very successful results with ${\pm}0.005%$ of percentage error for temperature, enthalpy and entropy and ${\pm}0.025%$ for pressure and specific volume. From these successful results, it is confirmed that the neural networks could be powerful method in function approximation of the steam table.
