Hospitals have a complex environment setting which may cause confusion amongst visitors and the tendency of them getting lost is possibly high. This article aims to highlight the wayfinding aids used by visitors in hospitals. However, there are barriers and challenges that may affect the success of wayfinding experience amongst hospital visitors. Three targeted factors, namely poor and unfriendly signage; inconsistent utilisation of the numbering system; and difficulty in navigating the hospital premise have been identified to be improved. Therefore, by incorporating these factors with a constant stimuli method with fixed images in an indoor public hospital environment, this may improve visitors’ experiences when navigating in a hospital.
Brucella melitensis is one of the major zoonotic pathogens worldwide with enormous
economic losses as well as considerable human morbidity in endemic areas. The global burden of its
incidence in both human and animal populations remains significantly at an alarming rate. The impact
of the disease is even multidimensional in nature and not always well understood and significantly
complicating effective policy response. The pathogenesis is complex and governed by several factors
working together in synergistic manner. The evolutionarily developed diverse evasion strategy to avoid
the host’s innate and adaptive immunity is further worsening the situation. Until recently,
lipopolysaccharide (LPS) remains the major virulent factor of B. melitensis and responsible for the
mechanism by which the pathogen causes its deleterious effects. Mechanisms presiding to the
colonization of the pregnant uterus in different animal species are still largely unknown. Information
related to the epidemiology and immunopathophysiology is still scarce in the database and control
programs are rarely implemented. Therapy is based on wide spectrum antibiotics with mysterious
outcome. The pre-existing vaccines appear not promising. Thus, understating the biological behaviour
of the disease becomes a fundamental issue. In this review, we highlight various key aspects of the
disease with special reference to the epidemiology and the immunopathophysiology of the disease in
sheep goat populations.
Awareness of recommendations for fruit and vegetable consumption has increased substantially over the last 20 years. In addition, fruits and vegetables such as pumpkin (Cucurbita moschata Duchesne) are good sources of many important nutrients, including potassium, vitamin C, folate, fibre, and numerous phytochemicals. Malaysia produces pumpkinits own, with considerably large areas of production comparable to its high global demand. However, in reality, there is a limitation in the commercial production as the local pumpkinis very much dependent on the market demand as the utilization has been limited to the consumption of fresh product. Thus, the objective of the study first initiative to provide the information about the pumpkinand second to investigatesthe opportunities on commercialized local pumpkinin Malaysia as by products despite various nutritious it is also listed as prophetic foods. The scientific research that covered a broad range of in vitro to in vivo studies on the by-products potentials of these fruits is also discussed in detail.The current review is an update for researchers to have a better understanding of the pumpkin, which simultaneously can provide awareness to enhance their commercial value and promote their utilization.Malaysia have potential to growth pumpkin instead of continuously importing. The daily consumption of pumpkins may provide various health benefits to human. Future investigation is needed to explore the potential of pumpkin as by products in order to increase its competitiveness and self-sufficiency.
Readymade garments (RMG) industry of Bangladesh are lesser revealed to sustainable outlines that originating avoidance related with standard health and safety provisions, labor rights, women safety, child labor, pollution, waste disposal and ground water depletion. Recently there are also several safety hazards by way of fire incidents and building collapses which caused death and injury of thousand or garment workers at Bangladesh. Actually a suitable sustainable development scheme for this industry includes the insights of proper employee involvement based upon what is known (knowledge) and done (behavior). So the study aims to investigate the relationship between knowledge and behavior which reflects the complication between what is in fact known and what is done in case of sustainable issues. The study has used both questionnaire survey and interview procedures on 10 BGMEA registered factories of Chittagong to recognize the connection between knowledge and behavior. The target populace of the study has been limited only to the white collar employees. However, the study identified that employee knowledge and behavior of sustainable development contains a moderate, positive relationship (r=.315, n=150, p
Nigella sativa (Black seeds) has been recognized as one of the most popular herbs in many
parts of the world for centuries. It was used in the world as folk medicine to cure different kinds of diseases. This plant has been considered as one of the main sources of nutrition and healthcare for humans as well as animals. It has been perceived as Kalonji; it is a southwest Asian plan t that flowers annually. The seeds and oil of this plant have been used in food; in addition, it has a long history in the making of medicines. In addition to its being a model plant for better realization of gene and chromosome relationship, the plant species is also significant cytogenetically. Plant based system has not been absorbed fully for human health care despite the remarkable advancements in the field of pharmacology. Cumin, as one of the medicinal plants gifted to humans by nature, has a number of potential uses. It has been proved to be a
useful herbal medicines that can be used for human health and therefore has been extensively studied and investigated to further discover the advantages of this plant.
Titania nanotube is gaining tremendous interest for its unique features including high
surface area, ion-exchange ability, photocatalytic potential and prominent electrical properties. Many
attempts were made to manipulate the unique properties of titania nanotubes for supercapacitor
application. In this review a comprehensive list of literatures on fabrication of titania nanotubes via
anodisation method in fluoride-based electrolytes and its application as supercapacitor are discussed.
This review shows that the nanotube morphology can be optimized by varying the anodisation
parameter such as electrolyte concentration, pH, voltage, and bath temperature. The review also
includes studies on the application of titania nanotubes as supercapacitor on improving the specific
capacitance value by doping with metal oxides and conducting polymers.
Feather waste is a potential renewable source to recover valuable products because it is being a rich source of keratin proteins and amino acids. It can be used to make feather meal, fertilizer and yarn sizing agent. Various treatments have been used to recover the protein from chicken feathers as the keratinous feathers cannot be easily degraded due to its tough structure. This paper reviews the existing treatment methods used to hydrolyze chicken feathers. The treatment methods for feather hydrolysis such as physical, chemical, biological and combined treatments as well as their advantages and challenges are highlighted. The effects of these treatments on feather hydrolysis are complex and vary in regards to the performance of feather hydrolysis and product yielded. Hence, it is important to choose an appropriate treatment method since the type of treatment applied affects the product yielded qualitatively and quantitatively. In addition, the economic assessment and environmental impact of the choice of treatment should be considered also.
The urban transit network design problem (UTNDP) involves the development of a transit route set and associated schedules for an urban public transit system. The design of efficient public transit systems is widely considered as a viable option for the economic, social, and physical structure of an urban setting. This paper reviews four well-known population-based metaheuristics that have been employed and deemed potentially viable for tackling the UTNDP. The aim is to give a thorough review of the algorithms and identify the gaps for future research directions.
Infectious bursal disease (IBD), also known as the Gumboro disease, has been a great
concern for poultry industry worldwide. The first outbreak of IBD due to very virulent (vv) IBD virus
(IBDV) infection in Malaysia was reported in 1991. The major economic impact of the disease is high
mortality and poor performance. The virus causes immunosuppression where if the infected chicken
recovered from the acute disease, they become more susceptible to infections of other pathogens and
fail to respond to vaccines. Therefore, prevention is important and vaccination has become the
principal control measure of IBDV infection in chickens. The conventional attenuated live and killed
vaccines are the most commonly used vaccines. With the advancement of knowledge and technology,
new generation of genetically-engineered vaccines like viral vector and immune complex vaccines
have been commercialised. Moreover, hatchery vaccination is becoming a common practise, in
addition to farm vaccination. Currently, the disease is considerably under controlled with the
introduction of vaccination. However, occasional field outbreaks are still commonly reported. The
demand for vaccines that could suit the field situation continues to exist. The endemicity of disease,
presence of challenge in the farm and maternally derived antibody in chicks are affecting the choice
vaccine as well as the vaccine development and vaccination strategies. In this review, advances made
in various vaccines that have been commercialised or under development, and challenges that they
face, are outlined. Furthermore, how the emergence of vvIBDV affect the progress of vaccine
development and influence its vaccination strategy are discussed.
Waterbirds serve as an important bio-indicator of ecosystem changes and have been used widely throughout the world. This is because they exhibit conspicuous and meaningful responses to the changes of the environment around them. Other qualities that make them a good bio-indicator are also highlighted. Thus, important information on their biology and ecology are essential to make informed decisions. This is crucial in order to better conserve them and their habitats. Currently they are facing new challenges that arise from continuous development throughout the world. In addition, many endangered species continue to declines and could be extinct if they are not protected and conserved. The development of artificial habitat such as wetlands to compensate natural habitat loss could be an alternative. However, detailed information on the waterbirds and their interactions with the new environment are needed in order to do so. It is further highlighted that few researches have been conducted and focused on the waterbirds particularly in Malaysia. Thus, we encourage more local young scientists to take up this challenge and equip themselves with the right knowledge and necessary skills as well as to remain relevant with the international research standards. Proper planning, funding and focus should also be considered by the government and local authorities to maximize the impact of the country’s conservation effort.
As reported by the World Health Organisation (2014), Malaysia is the fattest country among the Southeast Asia. Among others, obesity is a leading contributor of non-communicable diseases (e.g., type II diabetes, metabolic syndrome, and cancer). This article aims to review the exiting weight management programmes targeting overweight and obesity in Malaysia from 2005 to 2015. The findings from this review could be useful for future intervention efforts in an attempt to address such issues in Malaysia.
