Adopting sustainable and innovative building materials is becoming an ever-increasing necessity to reduce the impact of construction development on material resources consumption and climate change. Prefabricated construction has received an immense research attention recently, with precast concrete as the main prefabricated technique explored. However, there is a limited attention for innovative and composite materials and systems. Therefore, this research aims to investigate the recent development of innovative Industrialized Building Systems (IBS) in Malaysia. Literature review based on recent journal articles, government technical reports, companies' reports, and news articles were used in this study. The result of this investigation revealed that there has been a sharp increase in innovative system manufacturers from around 10 companies in 2010 up to 70 companies in 2020. This is primarily due to the advantages reported on innovative systems compared to bulky precast systems including design flexibility, efficient thermal performance, and green materials. This study provides better guidance for practitioners to better understand the innovative systems potential, leading to higher acceptance and greater use of the systems.

Optimization of energy supply net (ESN) can significantly increase their efficiency. A general approach to the thermoeconomic optimization of power supply networks with a single energy source is proposed. Typical examples of such networks are heat, water and gas supply systems. The developed method of ESN thermoeconomic optimizing on graphs and implemented algorithm are illustrated on a numerical example with arbitrary location of the energy source. The transition from existing power supply networks to optimized ones can significantly reduce the costs of their operation. Compared to the direct enumeration method, the search time for the optimum with this approach is reduced by more than 100 times. Bibl. 10, fig. 5.

Over time, a variety of composites are formed at the research and industrial level where not all the time the results are in favour. Various reasons exist in the formation of a composite in which the role of revolutions per minute (RPM) is one of them. Therefore, the aim of this research is to explore the impact of RPM in making the composite. For this purpose, multi-layer graphene (MLG) and polydimethylsiloxane (PDMS) was taken to formed two composites, in which one was prepared by adding the ethanol in MLG and later mixed with PDMS, and the other was prepared by direct mixing of MLG with PDMS. The physical and experimental inspection was made where the results reveal that a unique dispersion was achieved at low RPM in the first sample. However, the FTIR analysis revealed a less existence of MLG in both the formed composites. Although the low RPM speed was kept at 100, still less MLG sign was visible in the sample. Therefore, a further investigation is required to observe the loss phenomena of MLG within the composites due to the RPM speed.

Pavement degradation results due to both ecological and structural reasons. It is never easy to sustain the road to the exact specifications that were kept at the time of opening. With the passage of time, the pavement structure deteriorates. Hence, pavement distresses like different kinds of cracks, holes, and undulations start appearing. Maintenance is an essential practice in providing for the prolonged performance and the aesthetic manifestation of an asphalt pavement. Pavement maintenance aims to rectify deficiencies triggered by distresses and protect the pavement from further damage. The present research seeks to evaluate the distresses produced in flexible pavement. The northern bypass road located in Peshawar, Pakistan, was under consideration as a case study. A methodology was proposed to investigate the pavement condition, consisting of a manual survey performed as per the ASTM D 6433 standard. The pavement was split into different sections. Each section was further divided into sample groups. The kind and severeness of sample distresses were evaluated by visual scrutiny of the pavement sample groups, and the amount of each distress was quantified. This process required a crew of two engineers. It was inferred that identifying defects and knowing their roots could help improve rating pavement conditions and select cost-effective repairing methods. The periodic inspection was found to be necessary for providing current and valuable evaluation data. It was recommended that ratings should be updated every year.
路面退化既有生态原因，也有结构原因。要把这条路维持到开放时的精确规格，从来都不是一件容易的事。随着时间的推移，路面结构逐渐老化。因此，路面出现了各种裂缝、洞和起伏。维护保养是保证沥青路面长期使用和美观的必要措施。路面维修的目的是纠正因事故引起的缺陷，并保护路面免受进一步的损坏。本研究旨在评估柔性路面产生的痛苦。位于巴基斯坦白沙瓦的北部绕行公路正在考虑作为一个案例研究。提出了一种调查路面状况的方法，包括按照ASTM D 6433标准进行的人工调查。人行道被分成了不同的部分。每个部分进一步分为样本组。通过对路面样本组的视觉审查来评估样本窘迫的种类和严重程度，并对每种窘迫的数量进行量化。这个过程需要两名工程师。由此推断，识别缺陷并了解其根源可以帮助改善等级路面状况并选择具有成本效益的修复方法。认为定期检查对于提供最新和有价值的评价数据是必要的。建议每年更新评级。

Corporate sustainability concept emerged globally over the last two decades with the increased awareness of sustainable development by organizations. Following that, many empirical studies have tackled the industrial sector, which constitutes a vital part of the economy in most countries, and is one of the leading sectors in adopting the three dimensions of corporate sustainability (social, environmental, and economic). This quantitative study aims at developing and testing a conceptual model for assessing the impact of corporate sustainability adoption on organizational performance of this vital sector. The proposed model was empirically tested through a sample of 140 senior employees of eight industrial companies in three MENA countries (Bahrain, Saudi Arabia and Egypt). Non-parametric tests were employed to test research hypotheses. Results revealed a positive relationship between organizational performance, and the adoption of corporate sustainability measures for both environmental and social dimensions.

The aim of this study is to examine the association between the firm's ownership structure characteristics and the dividend payouts of the publicly listed non-financial companies in Gulf Cooperation Council (GCC) countries. The study applied a multivariate regression model and found a significant positive association between institutional ownership and the firm's dividend payouts. However, the study found no significant relationship between affiliate ownership and block ownership with the firm's dividend payout. The study findings can provide a valuable insight to the shareholders in GCC countries and aid in understating the impact of different ownership structures on the firm's dividend payout policies through the prospective of the agency theory. Also, the study can support the shareholders in reducing the agency problem by establishing a more effective ownership structure.

Pumice stone, known as the lightweight aggregate, is a mixture of lava and water used to replace coarse aggregate in construction. Nowadays, lightweight concrete has many applications in the concrete and construction industry. This study aims to overcome the project's cost and re-use the waste material dumped by the textile industry known as a pumice stone. Besides, an attempt has been made to compare the conventional concrete and lightweight aggregate concrete (LWAC) using a mix ratio of 1:1.5:3 and determine the strength parameters of LWAC. Lightweight concrete is made by partial replacement of coarse aggregate with different proportions of pumice stone ranging from 10%, 20%, 30%, 50%, 75% and 100%. Furthermore, several tests have been conducted to investigate mechanical properties such as compressive strength and tensile strength of lightweight concrete and compare them with conventional concrete. A total of 42 cylinders were cast and prepared, in which 21 cylinders were for compressive strength and 21 for tensile strength. Each set of 3 cylinders was cast for 10%, 20%, 30%, 50%, 75%, and 100%, making 21 cylinders for compressive strength and separate 21 cylinders for tensile strength with the same proportions. The experimental results show that the strength gradually decreases as the percentage of pumice stone increases. Therefore, up to 30% of lightweight aggregate as a partial replacement gives the desired compressive strength. Besides, the split tensile strength decrease when the percentage of pumice stone increases and gives the desired strength up to 30% replacement. Therefore, it is concluded that 30% replaced concrete can be effectively used for structural purposes, whereas 50%, 75%, and 100% can only be suitable for the non-structural members.

The private sector in Bahrain is booming and playing a vital role in executing women empowerment in all aspects. Therefore, this study has been conducted to measure the women empowerment practices in Bahrain's private sector, which is rapidly growing and developing. Furthermore, the authors have tackled this topic by designing a model consisted of six variables: company clear vision, administrative practices, Human resources strategies, career development programs, performance appraisal practices, and government regulations. Therefore, the authors selected four industries in the private sector (Education, Health, Financial and Telecommunication), which were surveyed using a quantitative research approach to indicate and assure the variability of participants. An online self-administrated survey reached a sample size of 301 Bahraini female staff identified by four industries in the private sector in Bahrain. The results of the study indicated that the model has a relationship with empowerment practices. Based on simple regression analysis, the highest positive impact on women empowerment was found from administrative practices/laws, followed by human resources strategies, career and development, performance appraisal practices, clear vision and mission about women, and finally, government encouraging practices. However, multiple regression analysis showed that administrative practices/laws, followed by career and development, and finally, human resources strategies, only have a statistically significant effect on women empowerment.

Therefore, this study has been conducted to measure the women empowerment practices in Bahrain's private sector, which is rapidly growing and developing. Furthermore, the authors have tackled this topic by designing a model consisted of six variables: company clear vision, administrative practices, Human resources strategies, career development programs, performance appraisal practices, and government regulations. Therefore, the authors selected four industries in the private sector (Education, Health, Financial and Telecommunication), which were surveyed using a quantitative research approach to indicate and assure the variability of participants. An online self-administrated survey reached a sample size of 301 Bahraini female staff identified by four industries in the private sector in Bahrain. The results of the study indicated that the model has a relationship with empowerment practices. Based on simple regression analysis, the highest positive impact on women empowerment was found from administrative practices/laws, followed by human resources strategies, career and development, performance appraisal practices, clear vision and mission about women, and finally, government encouraging practices. However, multiple regression analysis showed that administrative practices/laws, followed by career and development, and finally, human resources strategies, only have a statistically significant effect on women empowerment.","PeriodicalId":389608,"journal":{"name":"2021 Third International Sustainability and Resilience Conference: Climate Change","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-11-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127400183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
