Published: November 2019

Road traffic accidents represented as the third cause of “death and disease” also the major cause of death among young people aged 15-29 years. In recent decade consequential investigation has been conducted on road crash contributing factors. All these researches showed that the recurrence and severity of accidents depend on many causes, such as vehicle performance, roadway environment, and characteristics of road users. Despite many studies in this field, the function of human factors on road accidents, is still unclear, due to the complex human characteristics. The lack of comprehensive model or procedure for scrutiny and evaluating the human characteristics which contributed to road incidents, motivate us to review on previous studies in order to indicate the relationships between human factors and road safety. This paper focus on the natural driving behavior of drivers including hazard perception and risk-taking of drivers which is affected by age, perceptual/cognitive abilities and driving experience. The study clearly shows that the mentioned factors have a huge impact on road incidents. Therefore, this paper indicate and recommend a number of solutions in order to mitigate the severity and frequency of accidents caused by human errors. Also previous road safety studies will provide series of crucial information for improvement of driver licensing and their training procedure.

Published: November 2019

Due to the great importance of natural daylight in interior spaces, architects keep experimenting different techniques to achieve a good luminous environment. One of the techniques used in building design is the skylight. This study focuses on the impact of the skylight on internal spaces in schools with regards to daylight factor, glare, and cooling loads. Thirteen simulation cases, including the existing case, were simulated and analyzed using several software packages such as Revit, Ecotect and Radiance. The thirteen cases are categorized into three main groups: A, B, and C. Each category has set some fixed parameters in order to reach an optimum design compared with the existing case. After conducting the simulation and analysis, the sub-cases of Group-A failed to achieve a good luminous environment and therefore the results were rejected due to the large increment in cooling load. On the other hand, the sub-cases of Group-B showed considerable improvement in the cooling loads, but some of these cases had caused glare in the space. The sub-cases of Group-C were better than of those in Group-B. Herein, some of the results of this study were satisfactory compared with the existing case study. However, one of the cases in Group-B had the optimum case among the examined cases where all the results are within the accepted range.

Published: November 2019

Energy and cost savings from a PV installation in a dwelling is influenced by a number of variables including occupant behaviour and the feedback mechanism accompanying the PV system. This monitoring device can reveal the energy efficiency opportunities present in real-time. The same way an in-home smart metre shows how much energy is being consumed by a household, a PV metre highlights both the generated power and the amount being used at any point in time. Results from a field survey revealed that post-PV installation, there was increased electricity awareness and energy conservation amongst the households. It was further found that in addition to the presence of a feedback metre, conscious energy management efforts arising from the part of the PV adopters and users led to the energy and cost savings. Most importantly, it was revealed that the energy savings were primarily driven by PV efficiency limits. These findings were used to develop a PV efficiency cycle demonstrating how the energy conservation and use efficiency occurred. The study showed the implications and proposed ways by which PV can be promoted in emerging economies.

Published: November 2019

In traditional Malay architecture, decorative elements are defined as non-structural elements and as “additional member” of the building that contributes to aesthetic and functional aspects of the architecture. Its ornamentation, form and pattern particularly in woodcarving and bamboo weaving reflect the uniqueness of local craftsmanship and the master carvers. There are at least 16 (sixteen) decorative elements of the traditional Malay house that have been identified by previous researcher. Architecturally in Malaysia traditional houses were categorised based on roof design, spatial organization and geographical setting which finally this categorization was named after the states. Each traditional house is in the state of Malaysia signifying particular style and architectural characteristics of that particular state. This article discusses the study of those decorative elements on the traditional Malay houses in the state of Perak known as Rumah Limas Bumbung Perak (RLBP) and traditional house from the state of Johor known as Rumah Limas Johor (RLJ). With the objective is to investigate the type, terms and characteristics of decorative elements site observations were done on selected twenty-five (25) of RLBP houses and another twenty-five (25) of RLJ houses. The analysis on visual data and verbal data were carried out to established architectural terminology and typology based on form and style of every decorative element. The study found that nine (9) decorative elements come to be the major characteristics of RLBP whilst seven (7) for RLJ; some with different name, form and style from other states. These similarity and dissimilarity contribute to the extension of the aesthetical theory and philosophy of the Malay traditional house in Malaysia.

Published: November 2019

Adjudication is currently in its green age, where many lessons and experience are yet to be learnt. The implementation since its first introduction in 2012 has shown a progressive dynamic as it is widely applied, with many claims resolved, despite numerous being referred to arbitration and litigation. Challenges made against the adjudication decision under various bases and the court only allows for limited grounds for challenges. The paper aims to establish the valid approaches to challenge adjudication decision within the Construction Industry Payment and Adjudication (CIPA) Act 2012 implementation. The objectives include underlining the common problems occurring within the implementation through the behaviour of adjudication practice and studying the basis for challenges in adjudication decision. Law case analysis was carried out using thematic analysis by extracting court judgements from several law cases and categorizing them within a particular theme. Once the data with similar theme was filtered, deductive reasoning was used to extract the conclusion. Limited grounds for admissibility of challenges included a claim against adjudicator acting in excess of his given jurisdiction and/or adjudicator who is in breach of natural justice. Limited ground for challenges are important to ensure the relevance of the adjudication institution while maintaining the role of the judiciary in conserving the fairness and justice within its implementation.

Published: November 2019

Today, many recreational waterfront developments are only superficially pleasant as they lack significant design qualities needed by users. Notions on waterfront qualities create communication gaps between a designer vision and end-user perception. Designers might formulate objectives and ideas on waterfront qualities without adequately understanding the true needs and preferences of users, which encompass aspects deeper than merely visual features. This study evaluated the design quality of the recent development of Jeddah north Corniche. It aimed to analyse the relationship between physical patterns and users activity patterns, which will assert in understanding how seafronts physical pattern produces different social interactions; and how these activity–physical pattern relationships make this public realm work or not. This research employs questionnaires data collection method to interpret the activity patterns that appear to relate with particular use of design features. Analysing this relationship will conclude seafront socio-physical design principles, which take into account users preferences and the unique characteristics of Jeddah location and its Islamic culture, and encourage excellence in the design quality of urban waterfronts; focusing on creating prosperous, sustainable and liveable social environments. In addition, it will add insights and complement the application of urban design theories and practices, which could lead to further studies aiming to improve recreational seafronts design quality.

Published: November 2019

The need of clean water will continue to increase along with the increase of population. However, not all regions in Indonesia have a potential for raw water sources that meet standards to be treated into clean/drinking water, so an alternative water treatment needs to be developed. Peat water is one of water sources that is often found in lowland swamps or in tidal conditions which is much located in Sumatera and Kalimantan. Peat water requires an appropriate technology to be able to treat water into clean water. Peat water treatment using ozone plasma technology is one of technological breakthroughs that can treat peat water into clean water effectively and economically. Peat water used for this study is taken from Sintang, West Kalimantan. Tested Parameters of water quality will be compared with the Regulation of Minister of Health No. 416 Year of 1990. In this study, four parameters in raw water are carried out to be tested after treating with variations in length of contact time of 10, 12, and 15 minutes. Water quality parameters to be tested are turbidity, color, coliform, and permanganate with final quality of treating for each parameter are 5.8 NTU, 1.1 Pt-Co, below 2 MPN/100 mL, and 11.8 mg/L. There is significant decrease in a value of four parameters, which three parameters meeting the maximum limit. Permanganate as parameter that exceed the maximum limit, have high probability of meeting this limit if contact time of treating peat water with ozone plasma is extended.

More recently, concern on children’s well-being, health, mobility and upbringing has been increasingly being discussed. The child of today is the city-maker of tomorrow. Rapid urbanization impacts children the most as they have less access to the natural environment in the city. Moreover, in most developing nations including Malaysia, children opinions are not taken into consideration in the development of urban public spaces such as parks, playfields, streets and plazas. Living in an urban environment is not primarily about people relationship but rather the relationship between people, places and spaces. Realizing this, as the Malaysian urban population rapidly increases, the government and local councils have started to rethink and redesign urban spaces to sustain the basic needs and welfare of its citizen. Since neighborhood streets, public spaces, alleys and loose-fit spaces are essential spaces for children’s exploration and play, place-making is one of the favorite projects that many have chosen to use to create an urban environment that is child-friendly. According to Project for Public Spaces (2011), place-making is an integrative approach to better plan, design and manage the urban environment. It focuses on the cooperation and contribution of local communities to promote their safety and well-being. This paper attends towards children’s artworks impact to create a child-friendly environment in an urban environment. From a review of 50 articles in journals of various discipline which includes Environmental Psychology, Art Education, Urban Sociology, Children Cognitive Functioning and Children Geographies, it is understood that children’s participation in place-making an urban environment are influenced to three attributes: (1)artworks as a mode of place-making for a positive emotional sense-of belonging, (2) active participatory of children in creating artworks could cultivate community bond and social skills, and (3) public sphere are spaces for children to exhibit their sense-of-attachment. The review construes that place-making through art can contribute to create a child-friendly environment that is inclusive, healthy, nurturing and sustainable.

Productivity is regarded as one of critical importance aspects of construction projects success and persistently deliberated in research topics in the construction industry. Previous researchers have determined different factors that influence construction productivity in conventional construction project, but there is limited research on productivity particularly in green construction projects. To response to the issue, this paper aims to explore a comprehensive literature review to examine the existing knowledge of construction productivity, particularly in green construction projects. Content analysis is used to identify related matters concerning issues and key factors affecting construction productivity, henceforth, a dynamic strategies of productivity improvement are established. Findings from literature are summarized and a theoretical framework of construction productivity improvement strategies is constructed and proposed. The framework highlights the identified factors affecting productivity in green construction projects, as well as determines the improvement strategies to enhance the construction productivity. The framework will be the instrument for the future development and will assist the construction practitioners to plan efficient approaches for achieving productivity growth in green construction projects. An improved understanding on the key factors of the productivity performance would help policy makers and industry to prioritize their policies and actions, whilst keeping of the eminence in Malaysian construction productivity
