This paper deals with an economical sampling plan, recently being concentrated on and, namely, investigates how to determine the basic concepts to settle the sampling plan of a minimum cost. On an inspection of sampling, a Linear Cost Model of a cost function which is concerned with the representative cost dements, is established and by the investigation of its possible solution economical single sampling plan for recitying inspection by attribute is suggested.

Ecological Engineering (EE) refers to all sustainable engineering that can reduce damage to ecosystems and that adopts ecology as a base and safety as an orientation in order to implement conservation of biodiversity and sustainable development. In short, EE attempts to safeguard the ecological environment while any essential construction projects proceed. EE encompasses many fields, including construction skills, ecosystem preservation, landscape, and even related cultures and so on. Such variety results in greater complexity of construction, and, consequently, indirectly increases the difficulty of construction quality control. The objective of our research is to explore a promising model for EE via an extensive literature survey. This model includes three principal stages: plan-design, construction, and maintenance, along with individual accompanying phases concerned with quality control and vital management. In this article, a river restoration example is adopted to describe in detail the critical points of quality control in the three stages (plan-design, construction, and maintenance) of the construction life cycle. This study proposes an integrated structure for quality management of EE to guarantee its quality and to enhance its core applications in order to achieve long-lasting preservation of the environment.

Health benefits from implementing air quality control measures were assessed using the Environmental Benefits Mapping and Analysis Program (BenMAP). BenMAP developed by US EPA is a GIS-based software tool that estimates the health impacts and associated economic values connected with changes in ambient air pollution. Once a set of BenMAP-required data was collected, the health benefits from implementing Seoul Air Quality Management Plan (SAQMP), an official AQ improvement plan for Seoul Metropolitan Area, was assessed using BenMAP. The PM10 concentrations assuming the SAQMP implemented successfully were predicted with the MM5 (Mesoscale Meteorological model version 5)/CMAQ (Community Multiscale Air Quality) model. A PM 10 exposure related premature mortality function was adopted trom a well-known epidemiology study. Economic valuation functions driven from benefit transfer methods were utilized. Through the SAQMP, PM10 concentrations were estimated to be lowered by $15{\mu}g/m^3\;to\;75{\mu}g/m^3$ depending on air quality modeling grids. 5,569 premature deaths (95% CI $3,264{\sim}7,809$ deaths) could be avoided in the Seoul Metropolitan Area. The economic value of the deaths avoided was estimated to $13.2 billion $(95%\;CI\;$890\;million{\sim}$28.2\;billion)$ using the benefit transfer value. BenMAP could be a useful tool for developing effective air quality improvement policy, enabling the policy makers to anticipate the effects of regulatory changes on people's health and the economy.

An integrated water environment management system is necessary in improving water quality, properly allocating water resources, and supporting socio-economic development. Specifically, water quality management system using web map can be an efficient approach to accomplish this system. This paper aims to construct a dynamic water quality management system to reflect a water environment management system which includes three sub-models with consideration of their interrelationships (a socio-economic model based on dynamic Input-Output model, a water resources cycle model, and a water pollutants flow model). Based on simulation, the model can precisely estimate trends of water utilization, water quality, and economic development under certain management targets, and propose an optimal plan. This study utilized the model to analyze the potential of using reclaimed water to accomplish local water environment management and sustainable development plan while exploring the applicable approaches. This study indicates that the constructed water environment management system can be effective and easily adopted to assess water resources and environment while improving the trade-off between economic and environment development, as well as formulate regional development plan.

Currently the problem of air pollution caused by the motor vehicle emission is one of the most serious problems to be solved. Thus we needed the vehicle emissions audit procedure and technical innovation constraining the motor vehicle emission. The Korean Environmental Protection Agency currently audits automobiles for emissions compliance at assembly plants with multiple attribute multiple staged sampling plans. In order to establish the more reasonable audit procedure, the multiple staged sampling plan designed in this paper has been applied to the domestic vehicles by analyzing the statistic characteristics of the emission distribution. This paper summarizes the auditing procedure and develops methods for determining its statistical characteristics. Specifically, we consider how to evaluate a multiple staged sampling plan, give a procedure that efficiently estimates attribute-type probabilities from multivariate variables-type data, and quantify the effect of tightening the acceptable quality level of the sampling plan. As a result it can be proved that this audit procedure is the reasonable plan minimizing the AQL (Acceptable Quality Level) and is to be used effectively for the auditing procedure constraining the injurious gasses of the motor vehicles.

Purpose: For effective quality assurance activities, BOM-based quality assurance method is presented. This study introduces various BOM conversions such as Q-BOM, T-BOM, and S-BOM based on M-BOM structure. Methods: Product quality control via Q-BOM manages inspection/audit information, overall supply-chain of product, part requirements, and inventory status. T-BOM manages part traceability, and S-BOM enables statistical control over key process and parts at various hierarchy levels. Results: Quality plan template was developed based on the study results of BOM system including Q-BOM, T-BOM, and S-BOM. Conclusion: Through BOM(Q-BOM, T-BOM, and S-BOM) study and development of quality plan template, more systematic and comprehensive quality management plan is achieved.

본 연구에서는 현행 지적정보의 생성 및 품질 관리 방법의 검토를 통해 지적정보의 품질이 어떻게, 어느 정도의 수준으로 관리되고 있는지를 분석하였다. 그리고 이에 대한 문제점을 도출하고 이를 기초로 지적정보의 품질 수준 향상 방안을 제시하고자 하였다. 연구성과는 다음과 같다. 지적정보의 품질 관리의 방법과 수준을 검토하고 이에 대한 문제점을 도출한 결과, 현행 지적정보의 품질 관리는 도형과 속성정보를 포괄하는 품질 관리가 아닌 주로 위치정확도 부분에 국한되어 품질이 관리되고 있는 것으로 나타났다. 또한 공간정보 분야 품질 관리에 관한 국제표준(ISO 19113)기구에서 권고하고 있는 품질 측정 요소의 반영이 미흡한 것으로 나타났다. 이에 대한 개선방안으로 연구에서는 국제수준의 품질관리 방안, 품질 검사 공정의 도입 방안, 독립된 품질 검사 조직의 창설 방안 등을 제시하였다.

본 연구는 전형적인 도심소재 중 소하천인 오산천 상류를 중심으로 수질변화 현상을 정확히 파악하기 위하여 24시간에 걸친 연속측정을 통해 수질의 변화를 조사하였고, 이러한 결과를 통하여 효율적인 하천관리 방향을 제시하였다. 오산천 수질의 연속조사의 결과로부터, 본류의 수질개선을 위해서는 다음과 같은 일들이 선행되어야 할 것으로 판단된다. 첫째, 본류 수질개선을 위해서는 유입지류의 효율적인 관리방안이 필요하다. 둘째, 하천 본류의 저질로부터 재용출 되는 오염을 방지하기 위한 대처방안이 필요하다. 본 연구에서는 수질저하를 방지하기 위해 단순한 조사만으로도 중 소하천의 효과적인 관리 방안을 제시했다. 따라서 하천에서의 연속적인 수질 모니터링은 하천수질 개선을 위해 중요하며, 나아가 하천환경에서 일어나는 물질순환 및 물질수지는 건전한 하천조성을 위하여 정확히 평가되어야 한다.
