Survey Responses

Recently, demand for high-rise residential has increased every year and shifted residential development patterns from vertical to horizontal development. Living in high-rise residential will require residents to share common facilities and resources. For that, a management body is known as Management Corporation (MC) or Joint Management Body (JMB) is established. This management body is responsible to collect the service charge from residents, as well as managing and maintaining the buildings and common property. However, a review of the literature has found out gaps between the MC responsibility and residents’ satisfaction. Driven by study objectives, this study focuses on exploring issues faced by the tenants living in the selected high-rise strata housing. Through a questionnaire survey, responses are randomly collected and analysed. A descriptive table, Relative Importance Index (RII) and correlation test are used in the analysis to provide findings for the study.

The construction industry is recognized as one of the most hazardous industries globally. Moreover, the rising trend of urbanization in many developing countries has ushered in a new era of high-rise construction, thus increasing the frequency of hazards related to working at height. Accident records in Saudi Arabia reveal that the construction industry accounted for 46.4% of industrial accidents, while fall-related injury accounted for 27% of the recorded injuries. Scaffolding is the most common access equipment used to work at height. Thus, the first stage in controlling the risks of falls from a height may be to identify the causes of scaffold accidents. This study presents 36 causes of scaffold accidents classified into five relevant groups, which have been identified through a thorough review of the extant literature. Additionally, the causes have been arranged in a survey designed based on a Likert scale of importance. Subsequently, 120 copies were administered to construction professionals in the Eastern Province of Saudi Arabia, with a 75% response rate. The Relative Importance Index (RII) was adopted to analyze the feedback. The results revealed that the top three causes of scaffold accidents include: “insufficient bracing/anchorage” (RII of 0.927), “scaffolding erected by incompetent professionals” (RII of 0.926), and “missing/faulty guardrails” (RII of 0.919). This study is of potential benefit to concerned stakeholders in the construction industry.

Aktiviti-aktiviti yang dianjurkan di universiti tidak kira akademik atau bukan akademik haruslah boleh membentuk pelajar yang seimbang bukan sahaja dari aspek jasmani dan emosi, malah dari aspek rohani dan intelek juga. Walau bagaimanapun, trend terkini pelajar adalah kurang melibatkan diri dalam aktiviti-aktiviti anjuran universiti Oleh itu kajian ini bertujuan untuk mengenal pasti faktor penglibatan pelajar dalam aktiviti bukan akademik anjuran universiti dan mengenal pasti langkah-langkah yang boleh diambil supaya lebih ramai pelajar melibatkan diri dalam aktiviti bukan akademik anjuran universiti. Ia dijalankan terhadap 888 orang responden daripada 5,534 pelajar diploma di Universiti Teknologi Malaysia Kuala Lumpur (UTMKL). Berdasarkan kepada keputusan analisa menggunakan kaedah Relative Importance Index (RII), faktor pengaruh rakan telah dikenal pasti sebagai faktor yang paling mempengaruhi penglibatan pelajar terhadap aktiviti bukan akademik anjuran universiti iaitu dengan nilai RII sebanyak 0.79. Manakala faktor yang paling kurang mempengaruhi pelajar menyertai aktiviti bukan akademik anjuran universiti ialah faktor personaliti pelajar dengan nilai RII sebanyak 0.59. Maklum balas daripada pelajar berkenaan dengan langkah-langkah yang boleh diambil supaya lebih ramai pelajar melibatkan diri dalam aktiviti bukan akademik anjuran universiti dianalisis menggunakan kaedah Analisa Bertema. Maklum balas pelajar telah dikelaskan kepada 6 tema iaitu penambahan aktiviti yang aktif dan menarik, penambahan infrastruktur oleh universiti, menambah baik saluran komunikasi pelaksanaan aktiviti, merancang pelaksanaan aktiviti, sokongan universiti dalam bentuk kewangan dan memberikan galakan dan motivasi. Hasil daripada kajian ini boleh diguna pakai dalam membuat perancangan aktiviti akademik di universiti bagi menarik lebih ramai pelajar melibatkan diri. Kajian seperti ini harus dijalankan pada masa akan datang. Perincian mengikut jenis aktiviti bukan akademik dan perbandingan mengikut jantina terhadap faktor-faktor yang mempengaruhi penglibatan pelajar terhadap aktiviti bukan akademik dapat membantu dalam menjelaskan dan memperincikan lagi penglibatan para pelajar dengan lebih menyeluruh.

Abstract: Aim Identify seasonal variations in the diet of juvenile living in the estuary of the Parnaíba River Delta. Methods Food items were identified through analysis of stomach contents, and later submitted to analysis by regular methods for Frequency of Occurrence (FO), Frequency Numerical (FN), Gravimetric Frequency (FW) and Relative Importance Index (IRI). Results Juvenile diet of Elops saurus that inhabit the lagoons in the Parnaíba delta was composed in order decreasing of importance by Osteichthyes (Teleostei), Insecta and Crustacea in addition to Polychaeta and Nematoda. It was also observed a high frequency of occurrence of fragments of plastics in the diet. In the rainy season, 17 items were recorded in the diet, whereas in the dry season only 7 items were present. Relative Importance Index showed high presence of the Teleostei fish (69.93%) on diet of E. saurus during the rainy season, whereas during the dry period the insects of the families Corixidae (43.25%) and Dysticidae (39.16%). Conclusions With the study it was possible to identify that juvenile are piscivorous in the rainy season when there is a higher availability of prey in the environment and insectivores in the dry season when it reduces the supply of food, indicating feeding flexibility to environmental alterations.
