Predictive maintenance (PdM) is a key application of data analytics in semiconductor manufacturing. The optimization of equipment performance has been found to deliver significant revenue benefits, especially in the wafer fabrication process. This chapter addresses two main research objectives: first, to investigate the particular challenges and opportunities of implementing PdM for wafer fabrication equipment and, second, to identify the implications of PdM on key performance indicators in the wafer fabrication process. The research methodology is based on a detailed case study of a wafer fabrication facility and expert interviews. The findings indicate the potential benefits of PdM beyond improving equipment maintenance operations, and the chapter concludes that the quality of analytics models for PdM in wafer fabrication is critical, but this depends on challenging data preparation processes, per machine type. Without valid predictions, decision-making ability and benefits delivery will be limited.

Smoke taint has become a prominent issue for the global wine industry as climate change continues to impact the length and extremity of fire seasons around the world. Although the issue has prompted a surge in research on the subject in recent years, no singular solution has yet been identified that is capable of maintaining the quality of wine made from smoke-affected grapes. In this review, we summarize the main research on smoke taint, the key discoveries, as well as the prevailing uncertainties. We also examine methods for mitigating smoke taint in the vineyard, in the winery, and post production. We assess the effectiveness of remediation methods (proposed and actual) based on available research. Our findings are in agreement with previous studies, suggesting that the most viable remedies for smoke taint are still the commercially available activated carbon fining and reverse osmosis treatments, but that the quality of the final treated wines is fundamentally dependent on the initial severity of the taint. In this review, suggestions for future studies are introduced for improving our understanding of methods that have thus far only been preliminarily investigated. We select regions that have already been subjected to severe wildfires, and therefore subjected to smoke taint (particularly Australia and California) as a case study to inform other wine-producing countries that will likely be impacted in the future and suggest specific data collection and policy implementation actions that should be taken, even in countries that have not yet been impacted by smoke taint. Ultimately, we streamline the available information on the topic of smoke taint, apply it to a global perspective that considers the various stakeholders involved, and provide a launching point for further research on the topic.

Shared services have been widely used in many organizations as an alternative to outsourcing. For shared services, common services are standardized and consolidated across multiple organizations to reduce the operational cost and to increase information and knowledge sharing. Two major advantages of shared services over outsourcing are long-term stable cost-saving and knowledge sharing. One important aspect of successful operations management of shared services is to ensure the quality of services delivered by a shared service provider to each individual partner organization. This paper proposes a performance predictive analytics framework for operations management of shared services. The paper presents a case study to demonstrate the usefulness and effectiveness of this framework.

Abstract We develop a method to estimate the quality of processing routes in a wafer fabrication process. Ranking such routes can be useful for identifying the “best” and “worst” routes when making adjustments to recipes. Route categorization is also useful in developing efficient scheduling algorithms. In particular, we propose a method for ranking routes based on count-based metrics such as the number of defects on a wafer. We start with a statistical model to produce a “local” ranking of a tool and then build a “global” ranking via a heuristic procedure. Creating a fully statistical procedure for ranking routes in semiconductor fabrication plants is virtually impossible, given the number of possible routes and the limited data available. Nonetheless, our discussions with working engineers indicate that even approximate rankings are useful for making better operational decisions.

Abstract This paper examines the urban challenges, urban policies, sustainable urbanism, and opportunities of sustainable urbanism. Sustainable urbanism is a new term that prevails in urban planning and planning. This paper tries to put forth the need for sustainable urban development in Indian cities such as Delhi and Rajkot. Urbanization in India has led to an unsustainable situation. It offers the proven benefits of economic growth and development, but it also offers brings with it social and ecological challenges. Various challenges related to sustainability, spatial planning, Governance, shortcomings, and execution were discussed in this paper. Specific research questions are: what is sustainable urbanism, what are the challenges to cities such as Delhi and Rajkot, and what are the opportunities of sustainable urbanism in Delhi and Rajkot? People face many challenges that threaten the well-being of the environment, society, and quality of life. All of these challenges are complex and closely related, so one approach can have positive consequences for others. In the case of Delhi, the population growth is an extremely sensitive issue from a social and ethical point of view, has generally become a threat to the entire planet and especially to the metropolitan area, while in the case of Rajkot, increasing industrial, commercial and commercial activities has become threatening to the environment. In this study, I have also explored solutions and other issues that are important elements to discuss.

ABSTRACT This study addresses the effects of the art of clowning on the quality of life and wellbeing of a woman presented with aphasia and depression. She was discharged from individual Speech-Language Therapy due to improved language skills, but she continued expressing emotional complaints associated with communicative situations. The participant joined Palhafasia, a community project that welcomes aphasics for group clowning sessions. She participated for six months in once-a-week meetings that lasted three hours each. The comparison of pre- and post-intervention measures detected improvements in her quality of life, including communication and subjective well-being of the participant. This innovative case study provides a preliminary contribution that must be further investigated. The study points to the potential benefits of the practice of clowning to promote quality of life and well-being of people with aphasia who suffer from depression.

Study Aims. Evaluate the quality and effectiveness of the medication-assisted therapy (MAT) pilot in Kazakhstan and review implementation context and related challenges.Methods. We performed a desk review of MAT policy and program documents and reviewed medical records at three MAT sites in Kazakhstan. MAT patients(n=93)were interviewed to assess their perceptions of the program and its impact on their health, criminal, drug use, and HIV risk related behaviors as well as expenditures on nonprescribed psychoactive drugs. Persons injecting drugs who are not in treatment, MAT program staff, and other stakeholders were interviewed to obtain their perspectives on MAT.Results. Legislation supports introducing MAT as a standard of care for treatment of opioid dependence; however, its progress has been hampered by active opposition. Inadequate access and coverage, insufficient supply management, scarce infrastructure of narcological facilities, limited opportunities for staff development, and restrictive methadone dispensing policies compromise the quality of the intervention and limit its potential benefits. There were significant reductions in criminal, drug use, and HIV risk related behaviors in patients receiving MAT.Conclusions. The MAT pilot in Kazakhstan demonstrated its feasibility and effectiveness in the local context and is recommended for scaleup throughout the country.

Abstract The article presents the use of historical Polish post-war topographic maps and their usefulness in the detection and assessment of environmental changes caused by 20th century urbanisation. The case study area is the Polish city of Lublin. Two main research questions are defined and answered. The first is what kinds of maps can be used to trace environmental changes as well as to find the present-day remains of past environments and what is the reliability of these maps? Several series of topographic maps are used here together with aerial photography. The second research question is what changes can be found by comparing spatial sources and what features can be found today with the help of early maps. The main features investigated in this section are linear (road networks) and areal (orchards) supplemented with point features of various kinds (trees, wells, shrines). The quality of cartographic information is assessed and remnants of the past environment are discovered.

AbstractThis chapter focuses on the issue of shared physical custody (SPC) in the broader context of coparenting interventions. To identify if and how these interventions address the issue of SPC, we provide a systematic overview of the currently available types of coparenting interventions after marital dissolution. To be selected, the interventions had to be published in peer-reviewed journals, target separated or divorced parents, integrate work on coparenting, and include a custody focus within the intervention curriculum or as a targeted outcome. Finally, they had to be subject to empirical evaluation.As a second step, using a case study, we investigate how the issue of SPC may be addressed before divorce, during couple therapy. We describe the therapy sessions to highlight the factors that may protect or undermine the development of a cooperative coparenting relationship while separating, and eventually create a positive shared-custody scenario after divorce. We also analyse the couple’s progress regarding individual symptomatology and coparenting satisfaction based on self-reported questionnaires and on the quality of their observed coparenting interactions.From a therapeutic perspective, this chapter aims to deepen our understanding of the challenges and opportunities of coparenting during and after separation and its intertwinement with the issue of SPC.
