The Virtual Assembly Technology Consortium is a university/government/industry consortium that seeks to investigate the application of virtual assembly methods in mechanical system assembly processes. In this paper we report three categories of engineering case studies that have been developed by the consortium members over the past two years, describe the overall methodology, and then proceed to feature specific details of two key case studies. An engineering case study has been defined as an account of an engineering activity, event or problem containing some of the background and complexities actually encountered by an engineer, with the objective of providing a medium for learning. The objective of the case studies was to assist consortium members in demonstrating and validating the use of immersive virtual assembly technologies and tools in the simulation of factory floor manufacturing processes. What is of special significance is that instead of modeling simplified problems or perceived representative situations, the case studies were constructed from actual assembly floor projects and situations encountered at industry member sites and with considerable participation from industry engineers and manufacturing shop floor personnel. Based on the success of the case studies, the consortium members inferred that virtual assembly methods are poised to move out of the realm of special projects and test scenarios to deployment in the actual design and manufacturing cycle. However, in order to be truly accepted in industry, there are still issues to be addressed in terms of ease of use, portability of the applications, and preparation of the models for the evaluations. Thus, the case studies added a new dimension to the exploration and understanding of how this new technology could be of practical value in industry.

Pedagogical Approaches

This case study analyzes the availability and uses of teaching techniques and computing technologies in Grades 10, 11, and 12 Computer Applications Technology classes in a remote town in South Africa. The technologies and techniques trialed show promise of usefulness in being more engaging to student interest than the prior method. Human factors issues focus on ease of use and intuitiveness of technologies for both teachers and students. With 50-minute classes, if the technology becomes a hurdle rather than a vehicle for teaching a class concept, it defeats its own purpose. Thus, to be successful, technologies need to be selected carefully, matched to pedagogical goals, calibrated for student skills, installed, tested, and ready for use. Students need support, encouragement, and, occasionally, prodding to use new technology. Thus, ICTs in the classroom require a technologically and pedagogically knowledgeable teacher.

This paper presents a case study that addresses factors that influence unlearning at the individual level. These factors were studied in a public sector organization located in a country characterized by high power distance. The case organization went through a change process of a daily routine caused by the introduction of a new technology. Data were collected through semi structured face-to-face interviews with shop floor agents in the state of Santa Catarina/Brazil. The results highlight the strong influence of the support of formal leaders on the unlearning process of individuals, suggesting that managers operating in a high power distance environment have to make bigger efforts compared to their counterparts in small power distance settings to promote unlearning processes of employees. The study advances the limited body of knowledge regarding unlearning in general and unlearning at the individual level in particular. It also stresses the influence of the national cultural dimension on the unlearning process of individuals.

This case study details the process and lessons learnt from converting a compulsory comprehensive organisational survey from email to online format. The conversion was undertaken to improve data quality and reduce respondent burden. Key considerations in developing the online survey were ease of use, security and access. The new intuitive system allowed simultaneous access for multiple users, and incorporated dynamic indicators of progress and validation of numeric data. Reactions to the survey were mainly positive ? about 75% of user feedback was positive or neutral, they reported the survey was ?user friendly? and preferred the online format. Negative comments focused predominantly on the feature of expanding and collapsing questions which these respondents found difficult to manage. Administration of the survey was streamlined, with considerable reduction in time spent in checking and correcting responses for both respondents and data collectors. Although substantial improvements were recognised and appreciated by many users, it is important to acknowledge that users adapt to new technology at different speeds, and adequate support needs to be implemented for all users.

Zusammenfassung. Hintergrund: Die patientenbezogene Komplexität der Pflege ist durch die Merkmale „Instabilität“, „Unsicherheit“ und „Variabilität“ definiert. Aufgrund der reduzierten Aufenthaltsdauer und der steigenden Zahl chronisch und mehrfach erkrankter Personen erhöht sich die Komplexität der Pflege. Ziel: In dieser Studie untersuchten wir das Phänomen patientenbezogener Komplexität aus Sicht von Pflegefachpersonen und Pflegeexpertinnen im Akutspital. Methode: Im Rahmen eines kollektiven Case-Study-Designs schätzten Pflegefachpersonen und Pflegeexpertinnen die Komplexität von Pflegesituationen mit einem Fragebogen ein. Danach befragten wir sie in Einzelinterviews zu ihrer Einschätzung. Mittels Within-Case-Analyse verdichteten wir die Daten induktiv zu Fallgeschichten. In der Cross-Case-Analyse verglichen wir die Fallgeschichten hinsichtlich deduktiv abgeleiteter Merkmale. Ergebnisse: Die Ausprägung der Komplexität hing in den vier Cases im Wesentlichen davon ab, ob klinische Probleme kontrollierbar und prognostizierbar waren. Je nach individuellen Ressourcen der Patientinnen und Patienten stieg bzw. sank die Komplexität. Schlussfolgerungen: Komplexe Patientensituationen fordern von Pflegefachpersonen Fachwissen, Erfahrung, kommunikative Kompetenzen sowie die Fähigkeit zur Reflexion. Berufsanfänger und Berufsanfängerinnen werden zur Entwicklung dieser Fähigkeiten idealerweise durch erfahrene Berufskolleginnen oder -kollegen unterstützt und beraten.

This paper presents the evaluation of usersХ experiences in three intelligent lighting pilots in Finland. Two of the case studies are related to the use of intelligent lighting in different kinds of traffic areas, having emphasis on aspects of visibility, traffic and movement safety, and sense of security. The last case study presents a more complex view to the experience of intelligent lighting in smart city contexts. The evaluation methods, tailored to each pilot context, include questionnaires, an urban dashboard, in-situ interviews and observations, evaluation probes, and system data analyses. The applicability of the selected and tested methods is discussed reflecting the process and achieved results.

Current supply chain methods are having difficulties in resolving problems arising from the lack of trust in supply chains. The root reason lies in two challenges brought to the traditional mechanism: self-interests of supply chain members and information asymmetry in production processes. Blockchain is a promising technology to address these problems. The key objective of this paper is to present qualitative analysis for blockchain in supply chain as the decision-making framework to implement this new technology. The analysis method used Val IT business case framework, validated by the expert judgements. The further study needs to be elaborated by either the existing organization that use blockchain or assessment by the organization that will use blockchain to improve their supply chain management.

AbstractNonwovens are one of the most versatile textile materials and have become increasingly popular in almost all sectors of the economy due to their low manufacturing costs and unique properties. In the next few years, the world market of nonwovens is predicted to grow by 7%–8% annually (International Nonwovens & Disposables Association [INDA], European Disposables and Nonwovens Association [EDANA], and Markets and Markets). This article aims to analyze the most recent trends in the global export and import of nonwovens, to present two case studies of Polish companies that produce them, and to present one special case study of the market of nonwoven geotextiles in China and India, which are the Asian transition economies among the BRICS countries (Brazil, Russia, India, China, and South Africa).
