Conceptual Design Phase

This paper presents a life cycle assessment (LCA) method in different design process. This method can help product designers to make more environmental friendly design decisions in the design process. In this method, product’s LCA model is established in product conceptual design phase with the aid of decision matrix. Thereafter, the model is improved in the latter design phases, especially in product detail design phases. In this process, with the help of LCA software, designers can evaluate different design options and get LCA results when necessary to guide the design process. Finally, a case study of designing a coffee pot is provided in this paper to illustrate the efficiency and effectiveness of this method. The case study shows that the method performs very well in the design process. It can be used to help designers to make more environmental friendly design decisions.

The paper describes a possibility to improve project management in high-rise buildings construction through the use of various Project Management Life Cycle Models (PMLC models) based on traditional and agile project management approaches. Moreover, the paper describes, how the split the whole large-scale project to the "project chain" will create the factor for better manageability of the large-scale buildings project and increase the efficiency of the activities of all participants in such projects.

Large Scale Project

Interest in the role of large urban development (LUD) projects in regeneration efforts of cities has risen in recent years. Studies of their planning process have often focused on global cities, examining challenges associated with their joint (public–private) governance structure, as well as those emanating from the need to balance local and global needs and interests. With few exceptions, the ways in which these projects fit in with metropolitan aspirations of small and medium cities were largely overlooked. In this article, we explore how a large-scale project was used by local authorities to reposition a secondary city as a sub-metropolitan center. Using the case of the 1000-District (Mitcham HaElef) in the Israeli city of Rishon-Lezion, it argues that while the project was originally designed to resolve the city’s scarce employment problem, it was gradually used to endow it with higher-order urban qualities, re-situating it as a sub-metropolitan center in the Tel-Aviv area. To support our argument, we focus on the project’s housing and employment components, including changes they were subjected to along the planning process, as well as the marketing campaign, which sought to re-present the city as a viable sub-metropolitan alternative. Drawing on qualitative methods, including personal interviews and content analysis, the article illustrates how one city’s large project is instrumentalized to attain metro-scale objectives. In so doing, it contributes to a nuanced understanding of the complexity of LUD planning, its stated objectives at various scales, and implications for actors in and beyond metropolitan jurisdictions.

Exiting green building assessment standards sometimes cannot work well for large-scale public buildings due to insufficient attention to the operation and maintenance stage. This paper combines the theory of life cycle assessment (LCA) and building information modeling (BIM) technology, thereby proposing a green building assessment method by calculating the greenhouse gas emissions (GGE) of buildings from cradle to grave. Life cycle GGE (LCGGE) can be divided into three parts, including the materialization stage, the operation and maintenance stage, and the demolition stage. Two pieces of BIM software (Revit and Designbuilder) are applied in this study. A museum in Guangdong, China, with a hot summer and warm winter is selected for a case study. The results show that BIM can provide a rich source of needed engineering information for LCA. In addition, the operation and maintenance stage plays the most important role in the GGE reduction of a building throughout the whole life cycle. This research contributes to the knowledge body concerning green buildings and sustainable construction. It helps to achieve the reduction of GGE over the whole life cycle of a building. This is pertinent to contractors, homebuyers, and governments who are constantly seeking ways to achieve a low-carbon economy.

Technologies such as blockchain, big data, and the Internet of Things provide new opportunities for improving and scaling up the collection of life cycle inventory (LCI) data. Unfortunately, not all new technologies are adopted, which means that their potential is not fully exploited. The objective of this case study is to show how technological innovations can contribute to the collection of data and the calculation of carbon footprints at a mass scale, but also that technology alone is not sufficient. Social innovation is needed in order to seize the opportunities that these new technologies can provide. The result of the case study is real-life, large-scale data collected from the entire Dutch dairy sector and the calculation of each individual farm’s carbon footprint. To achieve this, it was important to (1) identify how members of a community can contribute, (2) link their activities to the value it brings them, and (3) consider how to balance effort and result. The case study brought forward two key success factors in order to achieve this: (1) make it easy to integrate data collection in farmers’ daily work, and (2) show the benefits so that farmers are motivated to participate. The pragmatic approach described in the case study can also be applied to other situations in order to accelerate the adoption of new technologies, with the goal to improve data collection at scale and the availability of high-quality data.

Language Pathology

The family described in this article provides an unusual opportunity to relate findings from genetic, histological, electrophysiological, psychophysical, and rehabilitative investigation. Although the total number evaluated is large (49), the known, living affected population is smaller (14), and these are spread from age 20 to age 59. As a result, the findings described above are those of a large-scale case study. Clearly, more data will be available through longitudinal study of the individuals documented in the course of this investigation but, given the slow nature of the progression in this disease, such studies will be undertaken after an interval of several years. The general picture presented to the audiologist who must rehabilitate these cases is that of a progressive cochlear degeneration that affects only thresholds at first, and then rapidly diminishes speech intelligibility. The expected result is that, after normal language development, the patient may accept hearing aids well, encouraged by the support of the family. Performance and satisfaction with the hearing aids is good, until the onset of the speech intelligibility loss, at which time the patient will encounter serious difficulties and may reject hearing aids as unhelpful. As the histological and electrophysiological results indicate, however, the eighth nerve remains viable, especially in the younger affected members, and success with cochlear implantation may be expected. Audiologic counseling efforts are aided by the presence of role models and support from the other affected members of the family. Speech-language pathology services were not considered important by the members of this family since their speech production developed normally and has remained very good. Self-correction of speech was supported by hearing aids and cochlear implants (Case 5’s speech production was documented in Perkell, Lane, Svirsky, & Webster, 1992). These patients received genetic counseling and, due to the high penetrance of the disease, exhibited serious concerns regarding future generations and the hope of a cure.
