BIM Enabled Sustainable Facility Management

The scope of facility management spans from traditional activities like repair & maintenance, health & safety, through to real estate management, financial management, change management, and even contract management, tender and procurement, construction, and demolition and disposal of the constructed facility. It therefore requires considering sustainability aspects of construction, which are better addressed through sustainable design strategies. A consolidated but holistic framework has been conceptualized to ensure sustainability in facility management, especially to practice in building and AEC (architecture, engineering and construction) sectors. Although testing and validation is needed, the conceptualized framework is expected to achieve sustainability in the relevant sectors

Human Resource is being Trafficked by Luring in the World instead of Using as a Resource: An Empirical Study of Human Trafficking in Bangladesh

At present human resource is being trafficked by luring in the world instead of using as a resource. This heinous crime and social scar have become a global concern recently. The uneducated and innocent feeble people are illegally immigrated seeking a better future abroad but they are abused. Data have been collected from primary and secondary sources by questionnaire and interview method. The development of any country depends on the development of human resource. But today the traffickers consider human trafficking as a profitable industry. They target some illiterate workers and take them abroad by promising lucrative job as well as an attractive salary that dreams the workers standard life leading opportunity. But the workers are not given the promised job abroad. They are used as a slave, forced or bonded labor or commercial sexual exploitation. Even the workers often face isolation, sexual abuse, fear, rape that can be caused by death. But if this human resource is used properly instead of abuse, they will be a great resource for any country

Greening Existing Buildings in Brunei Darussalam

Building is the largest consumer of resources and the biggest polluter of the environment, including energy consumption and greenhouse gas emission. Greening existing buildings, an extension of green building concept to existing buildings, can potentially help to improve such issues. Greening process can considerably reduce energy consumption in buildings and thereby reduce the carbon dioxide emission. On the basis of a recent study on energy consumption in residential buildings in Brunei Darussalam, this paper demonstrates the potential savings in energy consumption and reduction of energy cost, if modern and energy-efficient electrical appliances are used in place of the existing conventional features/appliances. The results show that an average household can potentially reduce its yearly energy consumption by 32.74% and they can save annual energy cost of up to 52.20%. It is also seen that the appliances with higher energy consumption, like air conditioners and refrigerators, can offer higher savings of both energy consumption and energy cost, with relatively smaller extra initial replacement costs. A favourable awareness programme by appropriate authority is likely to motivate people to use such practices and help to reduce energy consumption and emission of greenhouse gases

Adopting Industry 4.0 in Construction Industry

Industries are often restrained to meet their aim in relation to productivity. This is due to the complexities and capabilities such as to cope with changing environment, for example technological developments and digitisation. Low productivity and ability for innovation are argued to be caused by the traditional nature of some industries. Hence, modern technology and/or concept like Industry 4.0 were developed for such industries to succeed in the modern world. This includes construction industry that demands for improvements to meet the clients’ needs such as faster production, increased quality and budget control. Thus, construction industry may benefit greatly by adapting to Industry 4.0 environment. This paper aims to address how construction industry and Industry 4.0 converge together, by focusing on the managerial efforts in construction industry: project management and strategic management. This paper is based on review of literature to examine the managerial efforts and relevant sets of critical success factors that have greater influence on construction industry, and establishing the importance of Industry 4.0 to construction industry. A framework has been conceptualised to show how construction industry links to Industry 4.0 by focusing on the managerial efforts. Future study in real life environment is required to support the components of the proposed framework, as well as to test and validate its application amongst practitioners

Green Roof Retrofit: A Case Study

Retrofitting green roofs on existing buildings efficiently reduces building energy consumption, and variation of indoor temperature. Despite such clear benefits, green roof is not widely practiced, probably due to a number of reasons. Different types of green roofs vary from as simple and thin as 5-cm thick grass covering to as complex as a fully designed park with trees, with weight varying from 15 kg/m2 to over 350 kg/m2, and significantly different installation cost. Moreover, the load capacity may be the predominant constraint, and a structural survey may be required to allow the retrofit. In other words, a thorough investigation is needed to examine roof load capacity, identify green roof type, and determine the cost involvement. Therefore, this paper demonstrates a step-wise decision-making process for a green roof retrofit/construction project, through a case study, in terms of accessibility to roof, structural capacity, type of green roof, ease of construction and maintenance and cost involvement, to suit the prevailing conditions of existing building. Within the allowable load capacity and availability in the local market, the study revealed that semi-intensive type of green roof is the cheapest, with installation cost of Brunei $208/m2 and monthly maintenance cost of Brunei$1/m2, compared to ‘modular extensive’ and ‘intensive’ types. The outcomes ae expected to allow policy makers to devise suitable program in Brunei for undertaking green roof retrofit projects to improve energy performances of existing buildings. Although the outcomes cannot be generalized elsewhere, the methodology developed can be applied for investigating specific cases under certain condition and targeting suitable solutions

An Overview on the Development of mRNA-Based Vaccines and Their Formulation Strategies for Improved Antigen Expression In Vivo

The mRNA-based vaccine approach is a promising alternative to traditional vaccines due to its ability for prompt development, high potency, and potential for secure administration and low-cost production. Nonetheless, the application has still been limited by the instability as well as the ineffective delivery of mRNA in vivo. Current technological improvements have now mostly overcome these concerns, and manifold mRNA vaccine plans against various forms of malignancies and infectious ailments have reported inspiring outcomes in both humans and animal models. This article summarizes recent mRNA-based vaccine developments, advances of in vivo mRNA deliveries, reflects challenges and safety concerns, and future perspectives, in developing the mRNA vaccine platform for extensive therapeutic use

Artificial RNA Motifs Expand the Programmable Assembly between RNA Modules of a Bimolecular Ribozyme Leading to Application to RNA Nanostructure Design

A bimolecular ribozyme consisting of a core ribozyme (ΔP5 RNA) and an activator module (P5abc RNA) has been used as a platform to design assembled RNA nanostructures. The tight and specific assembly between the P5abc and ΔP5 modules depends on two sets of intermodule interactions. The interface between P5abc and ΔP5 must be controlled when designing RNA nanostructures. To expand the repertoire of molecular recognition in the P5abc/ΔP5 interface, we modified the interface by replacing the parent tertiary interactions in the interface with artificial interactions. The engineered P5abc/ΔP5 interfaces were characterized biochemically to identify those suitable for nanostructure design. The new interfaces were used to construct 2D-square and 1D-array RNA nanostructures
