This paper deals with the present scenario of hazardous waste management practices in Thailand, and gives some insights into future prospects. Industrialization in Thailand has systematically increased the generation of hazardous waste. The total hazardous waste generated in 2001 was 1.65 million tons. It is estimated that over 300 million kg/year of hazardous waste is generated from nonindustrial, community sources (e.g., batteries, fluorescent lamps, cleansing chemicals, pesticides). No special facilities are available for handling these wastes. There are neither well-established systems for separation, storage, collection, and transportation, nor the effective enforcement of regulations related to hazardous wastes management generated from industrial or nonindustrial sectors. Therefore, because of a lack of treatment and disposal facilities, these wastes find their way into municipal wastewaters, public landfills, nearby dump sites, or waterways, raising serious environmental concern. Furthermore, Thailand does not have an integrated regulatory framework regarding the monitoring and management of hazardous materials and wastes. In addition to the absence of a national definition of hazardous wastes, limited funding has caused significant impediments to the effective management of hazardous waste. Thus, current waste management practices in Thailand present significant potential hazards to humans and the environment. The challenging issues of hazardous waste management in Thailand are not only related to a scarcity of financial resources (required for treatment and disposal facilities), but also to the fact that there has been no development of appropriate technology following the principles of waste minimization and sustainable development. A holistic approach to achieving effective hazardous waste management that integrates the efforts of all sectors, government, private, and community, is needed for the betterment of human health and the environment.

As the current review of Department of Defense (DOD) structures, capabilities, and plaits are coming to completion and moving into implementation phases, a focus to maintain is the delivery of mission capabilities for the front line warfighters. The mission capabilities packages are supported by the material, and also by the materiel support process, which includes not only the hardware, but more importantly the people, training, maintenance and support, and the doctrine, concepts of operations, tactics, techniques, and procedures for the material. Following an updated discussion on operational engineering, this paper expands the authors' concept of operational engineering, to several applied logistics options and discussions in support of rapid decisive operations. It finishes with an introductory discussion of a logistics commander operational planning tool, which potentially can support and enable generation of rapid decisive operations. This tool could assist combatant commanders and their warfighters to operate inside the decision cycle of opponents on the front lines. Further, the concepts addressed align with the Quadrennial Defense Review 2001 task: to "Provide sufficient mobility, including airlift, sealift, prepositioning, basing infrastructure, alternative points of debarkation, and new logistical concepts of operations, to conduct expeditionary operations in distant theaters against adversaries armed with weapons of mass destruction and other means to deny access to U.S. forces" [emphasis added](QDR 2001).

2002 IEEE International engineering management Conference

作者： Shaw, Wade H. Engineering Management Program College of Engineering Florida Institute of Technology Melbourne FL 32901 United States

The theory and practice of engineering management has developed rapidly in the last forty years to yield a discipline with considerable scope and focus. Educational institutions around the world report significant student interest in this field of study and enrollments are steadily growing as engineers and scientists focus their efforts on developing products and services that produce a business result. The concept of managing engineering and technology has emerged as an area of professional practice that is clearly a career path for many engineers. Yet, even with this growing awareness of the need to manage the innovation process, it is still common to hear discussions of "What is engineering management?" Some engineers feel that this discipline is simply an extension of their existing specialty with management training added on. Others view the field as a variation of basic management with adjustments for managing technical people. Some debate how engineering management is related to other disciplines such as industrial engineering or technology management. There is a need to clarify the definition of the discipline in order to establish a succinct and useful understanding of the role of engineering management in our society. In this paper a definition of engineering management is presented that links what engineering managers do, how they do it, and for what purpose. Fundamentally, engineering management is the process of envisioning, designing, developing, and supporting new products and services to a set of requirements, within budget, and to a schedule with acceptable levels of risk. The concepts of product and process complexity, systems analysis, risk management, and requirements engineering are used to distinguish the unique features of engineering management that make it a very real discipline of research, study, and practice.

Conventional and geo-spatial Environmental Impact Assessment (EIA) techniques are compared using pollution from shrimp farming as a case study. Conventional EIA procedures involved sampling and analysis through site visits. Results are presented as cause-effect-impact matrices. The geo-spatial EIA procedure involved sampling and analysis and fitting mathematical models for the spectral reflectance data obtained from satellite imagery. The mathematical models generated were then used to assess the spread of pollution over large areas, at different time intervals. This analysis showed that the geo-spatial EIA procedure offers advantages such as spatial and temporal variability as compared to conventional EIA procedures. © 2002 Elsevier Science Inc.

Farmers are using skimming wells to supplement their canal deliveries. To ensure sustainable groundwater extraction, proper design and operational guidelines for these skimming wells are required. The starting point of such guidelines is to look at farmers' existing groundwater extraction practices, their extent and associated problems. For this purpose, a field survey was conducted in the Indus Basin of Pakistan. Participatory rural appraisal identified several design and operational problems with farmers' skimming wells. These include: depth of well, number of strainers, horizontal distance of strainers, priming, water quality, sand in pumped water, and reduction in well discharge with time. To investigate these problems, diagnostic analysis was carried out. A test borehole was drilled to obtain water samples along the aquifer depth during drilling. The depth of well was then decided on the basis of these water quality analyses. To decide the number of strainers, a pumping test was conducted at the test borehole to estimate the contribution of individual strainers and the numbers were then increased according to the desired discharge. Similarly, placing a non-return valve between blind pipe and strainer solved the priming problem. Operating wells intermittently rather than continuously solved the problems of water quality and reduction in well discharge. The systematic approach adopted in this study helped the farmers to rectify the problems.

The design of wholesale electricity markets through deregulation has focused almost exclusively on the development of competitive supply (generation). The demand side of the market has been virtually ignored. Mostly, this is due to the assumption that electricity demand is almost completely inelastic. As a result, deregulated wholesale markets universally fail to pass price signals down to the end-users. This paper challenges the assumption of inelastic demand by exploring the potential benefits of implementing a simple load control scheme. This load control scheme allows consumers to shift demand from high priced hours to low priced hours during the day. The benefits to the individual consumer are explored through an example applied to residential air conditioning using price and demand data from California. This example shows that "smart" use of air conditioning can lead to great savings for residential consumers, without sacrificing comfort. The potential for multiple consumers implementing load control to reduce wholesale prices is also examined.

A parametric review of the built environment sustainability literature

引用

International Journal of Environmental technology and management 2002年第1-3期2卷 54-93页

作者： Pearce, Annie R. Vanegas, Jorge A. Sustainable Facilities and Infrastructure Program Georgia Tech. Research Institute Atlanta GA 30332-0837 United States Construction Engineering and Management Program School of Civil and Environmental Engineering Georgia Institute of Technology Atlanta GA 30332-0355 United States

The literature on built environment sustainability has grown dramatically in the past 10 years. Despite the proliferation of literature, there is still no consensus on how comprehensively and uniformly to define the concept of sustainability as it pertains to the built environment, nor is there consensus on what aspects of the built environment should be considered in evaluating the sustainability of a built facility. This paper, through an evaluation of selected sources from the sustainability literature, takes a first step in systematically identifying what parameters of both the built environment and the concept of sustainability are emphasised in the existing literature on the topic. The outcome is a set of parameters that can be used in future research to begin uniformly and comprehensively to define sustainability as it applies to built facilities, using techniques such as concept mapping, content analysis, dendograms, and other established research methods.

Defining sustainability for built environment systems: An operational framework

引用

International Journal of Environmental technology and management 2002年第1-3期2卷 94-113页

One of the ongoing challenges in the quest to make our built environment more sustainable is defining what sustainability means in terms understandable to and measurable by built environment decision makers. This paper illustrates one approach to developing a comprehensive and exhaustive definition of sustainability for the built environment: deriving domain-specific variables from fundamental principles and constraints that govern how earth systems work. The paper uses the concept of systems to define characteristics and critical constraints of both the earth as a whole and built facilities in particular. These constraints provide a basis for identifying conditions which must be met in order for a built facility system to be sustainable. The contribution of the paper is a decision space based on required sustainability conditions that can be used to evaluate facility alternatives in terms of their relative sustainability.

The process of new product development or new product introduction has been changed due to the concept of concurrent engineering and globalization. It requires frequent interactions among various design teams and customers. Therefore a collaborative environment has to be established to handle all the interactions and communications in production design. In this paper a low cost collaborative environment is used for product design. This primitive but innovative collaborative environment can be applied in the teaching of product design. The instructor, student team members, and even industrial partner can participate in the product design together. Team members at different locations and times can collaborate through the web-based environment and provide feedback to each other. This approach can provide students with better inputs to their design, better use of information technology, and better interaction with potential industrial collaborators.
