And Performance

Roundabouts are hastily spreading around the world, mainly because of their good safety performance, and several countries have recently updated their standards and guidelines. However, inconsistencies in design standards and practices are observed. In this paper, a critical review of the Australasian, EU, and US standards and guidelines is performed. As a result, key issues of the existing standards are identified, along with research areas to fill the knowledge gaps and recommendations for improvement in a case study, Italy. These recommendations are mainly based on the concepts of design flexibility and performance based design. Indeed, rigid standards, which do not really take into account safety and operational consequences of the design decisions and the need to balance opposing demands, might produce undesirable outcomes.

Manufacturing Readiness

This chapter aims to provide a new readiness matrix called ‘innovative manufacturing readiness levels (IMRLs)’ to evaluate and assess the areas of micro and nanotechnology maturity including their performance. The study employs a case study approach through which the practicability and applicability of the IMRLs conceptual matrix were verified and confirmed. A case study with laser-based manufacturing technologies explores the stages of micro and nano technologies (MNTs)’ maturity, including the key issues and performances that contributed to the development of a new assessment tool. Concerning intense global R&D competition in MNTs, this study exhibits a forward-looking approach in assessing MNTs maturity and performance. A generic conclusion is reached by which product designers and technology managers position themselves and take into account risk reduction exercises related to MNTs. The novelty of the research could be that organizations, which develop and use MNTs, have an opportunity in applying such a specific assessment matrix to quantify the technology readiness of unreleased MNTs.

The article presents the aplication of the biocenotic tree assessment method in the "Vila Mîndîc" park (Moldova). While conducting the inventory, preliminary design decisions were taken into account, which also influenced the determination of tree values. By extending the plant valorisation to the study of health, including safety for humans, the results were obtained to carry out the project. Particular areas were selected, which regardless of the conditions, must ensure safe stay; parts of the area where visiting the park is restricted and those where, due to high biocenotic values (including protection of animal breeding and nesting sites) communication routes and leisure areas are not planned. On the basis of the research, areas of exceptional importance for animals were identified and a conceptual land development project was carried out to accommodate human recreational needs.

Flooding Period

The recent flood event occurred in 2014 had caused disastrous effects in Peninsular Malaysia in states of Kelantan, Pahang, Terengganu, Perak, Johor and Perlis. Perak state was reported with 12,115 victims from 2,896 families registered at 77 relief shelters. There are several issues encountered by the victims and related agencies which caused inconveniences and interruptions during the flooding period. Besides, the usage of public buildings as relief shelters contributes to deterioration of the infrastructures whereby their suitability, convenient, capacity and safety might not be optimum for longer period of time. This paper focuses on the assessment of relief shelters established in Perak Tengah district, Perak. Standards and guidelines for relief shelters were reviewed according to the most relevant agreed principles for humanitarian response. Data and information in this study were obtained from survey activities, interview sessions and observations. In Perak Tengah, more than 50% of the previous relief shelters were public buildings with low capacity areas. Strategic location of shelters with proper design standards should be established to ensure safe and healthy environment for the victims. Findings from this paper provide important outcomes to serve as better preparation in handling future disaster.

Abstract Tall buildings present some specific aspects influencing the modeling and response to seismic loads. Therefore, the design rules recommended in codes, calibrated for low and medium rise buildings, are not appropriate for design of tall buildings. Other rules are needed, and performance based design represents a viable alternative for tall buildings. In this paper a methodology for the design of tall structures is proposed and it is illustrated trough a case study for a structure with perimeter tube and interior core walls, which aims to identify the particularities regarding the design, behavior and the parameters that define the post elastic behavior at the global and local level, for this structures.

Event Based

The growth of the event sector is underpinned by the demand of organizing a business event.  Thus, it leads to an increase in economic and social impact. However, the problems from the growth of this sector potentially results from the use of several event materials, transportation and infrastructure development.  Organizing a green event is seen as one of the strategies to reduce the environmental impact.  Therefore, the aim of this paper is to explore the issues involved throughout the process of greening an event by applying Mair and Jago Model.  Semi-structured interviews were conducted with event managers from six Malaysia business event companies that encourage green practices during their event.  Findings suggest that impact, initiative, support and performance motivates event organizers in organizing a green event.  It has also been found that knowledge, resources and behaviour are the barriers faced by event organizers throughout the process of organizing a green event.  Based on the findings it appears that two important factors have emerged from the data collection and analysis that showed a deviation from the Mair and Jago Model, namely “impact” for the motivation element and “support” for the barrier element.  The main limitation of this study was the scope of the study; as it only focuses on business events.  However, as the main purpose of this study is to explore the issues of organizing a green event, it has been found that there are other issues need to be explored in other contexts and geographical area.  Apart from this, as this is a case study, it can only replicate according to the circumstances of this case study. However, this study can be generalized in terms of the theory that has emerged from it.  It is suggested that further research should explore more issues in other contexts and geographical areas.

Librarian 2.0 adopts user-centered approach. This paper reports the case study of a community-based participatory approach for training librarian 2.0. The findings suggest that this approach allows the students to practice user-centered interactions, identify and integrate the user’s needs into design decisions, and develop ways of collecting the user’s feedbacks.Les bibliothécaires 2.0 adoptent une approche centrée sur l’utilisateur. Cet article présente une étude de cas sur une approche participative et communautaire visant à former les bibliothécaires 2.0. Les résultats suggèrent que cette approche permet aux étudiants d’interagir avec les usagers, d’identifier les besoins, de les intégrer dans leur processus décisionnel et de développer des moyens de recueillir les commentaires des usagers.
