A Survey on Building Safety after Completing the Construction Process in Malaysia Using Statistical Approach

Building condition is an important issue in all over the world to enhance safety, health and sustainability of built environment. The objective of this study is to determine the most frequent causes of building failures in order to avoid the building from collapses, cracks and so on. The collection of data has been done among the engineers, workers and public. The questionnaire was distributed among engineers, contractors and public with 100 respondents. This survey focuses on two main parts of the safety which are building design and building management. The building designs are divided into four main criteria which are building structure, service design, building fitting and hazard environment. Meanwhile, the item of building management is focused on the management criteria. Results are analysed using statistical approach. Structural equation modeling (SEM) is used to evaluate the efficiency of the models’ fitness and goodness. The survey shows that all criteria are importantly needed in maintaining the safety of building after completing the contraction process

Sample size calculations made easy using G*Power

G*power is a free software that helps researchers to calculate the sample size needed when conducting a research. The importance of sample size calculation is imperative for the knowledge of researchers. Sample size is very important in designing and planning a successful research as it involves time and financial planning. What is best about the G*power is that researchers can plan the real sample size according to their study design, such as minimum sample size for regression analysis with three predictor variables. This technique is commonly used when researchers need a quick decision on: “What is the sample size needed for an analysis?” This brief book illustrates how sample size is calculated based on specific statistical test. The step-by-step and simple discussions through simple presentation and easy-to-understand language used in this book help researchers to understand better about the sample size calculations. http://www.penerbit.usm.my/index.php/buku/261-sample-size-calculations-made-easy-using-g-powe

Mesin pembungkus nasi lemak

Pada era globalisasi ini, makanan tradisi melayu semakin berkembang dengan permintaan yang sentiasa meningkat saban tahun. Promosi hebat dan kesan media sosial telah menyebabkan tarikan yang kuat terhadap makanan tradisional Malaysia ditambah pula dengan kaedah hiasan yang kreatif dan menarik. Antara makanan tradisi melayu yang mendapat permintaan tinggi adalah Nasi Lemak. Nasi Lemak sangat sinonim dengan negara Malaysia sehinggakan ianya menjadi menu tetap sarapan pagi bagi setiap gerai mahupun hotel di negara kita. Penjualan nasi lemak sangat popular dan meluas. Permintaannya meningkat bukan sahaja di dalam negara, bahkan di peringkat antarabangsa juga nasi lemak mempunyai peminatnya yang tersendiri. Bagi syarikat penerbangan milik Malaysia seperti Airsia dan MAS, Nasi Lemak menjadi pilihan hidangan untuk penumpangnya yang terdiri daripada pelbagai warganegara serata dunia. Selain itu, faktor berlakunya peningkatan permintaan terhadap nasi lemak adalah kerana ianya tidak lagi hanya menjadi menu sarapan pagi semata-mata, malah ia juga menjadi menu makanan sepanjang masa sehingga ke lewat malam

Proving the efficiency of alternative linear regression model based on mean square error (MSE) and average width using aquaculture data

Multiple linear regressions (MLR) model is an important tool for investigating relationships between several response variables and some predictor variables. This method is very powerful and commonly used in finance, economic, medical, agriculture and many more. The main objective of this paper is to compare mean square error (MSE) and the average width between alternative linear regression models and linear regression model. The alternative method in this study is a combination of four methods, namely multiple linear regression method, the bootstrap method, a robust regression method and fuzzy regression through the construction of algorithms by using SAS software. Typically, the alternative method optimized by minimizing the mean square error (MSE) and average width. The results of the study showed a positive improvement for the estimation of parameters generated through these alternative methods. © BEIESP

Categorical data analysis using SPSS for periodontology

Statistics is a very powerful tool for data measurement. It can give meaning to meaningless numbers. On the basis, data can be classified as categorical or continuous. This book focuses on categorical data analysis. Categorical data classifies an observation to one or more categories. To get a clear understanding on how to analyze categorical data, this book emphasizes on categorical data analysis, especially for all beginners among dental students, dental researchers and dental lecturers. It is a compulsory method of analysis that researchers should learn, as it provides core skills that will be very useful for conducting categorical data analysis. Besides that, this book gives the researchers an idea on how to design a study that will optimize the output of the research study

Guttaflow bioseal as monocone obturation technique in curved root canals. A scanning electron microscopy study.

The obturation with GuttaFlow Bioseal (GFB) in curved root canals is not clearly investigated due to the new generation of root filling material. This study compared the obturated surface area, extrusion of root filling material beyond the apical foramen and duration of obturation procedure in curved root canals using monocone obturation technique. Access cavity was prepared on twenty human mandibular molars. The root canal curvature of more than 10 determined according to Schneider’s method was included. Samples were prepared using Hyflex CM rotary files and divided into two groups (n=10). Group 1 [gutta-percha (GP) cone and GFB] and Group 2 [GP cone and RoekoSeal Automix root canal sealer]. The duration of obturation procedure was recorded and the obturation radiograph was taken. Samples were bisected and the mesial roots were sectioned horizontally to obtain 3 root segments; apical, middle and coronal. All resected roots were mounted on brass stubs, sputter-coated with thin platinum coating and observed under scanning electron microscope (SEM) at 70x magnification. The SEM images were transferred to the SketchAndCalc Area Calculator software. There were no statistically significant differences on the obturated surface area and extrusion of root filling material between Group 1 and 2 irrespective of the status of root canal curvature. The duration of obturation procedure in severe root canal curvature between Group 1 and 2 exhibited statistically significant difference. The obturated surface area and extrusion of root filling material were not affected by the status of root canal curvature. The duration of obturation procedure with GFB in severe root canal curvature was slightly longer. Neither root filling material was able to seal the curved root canal of mandibular molars completely. Both root filing materials in the present study can be opted depending on the clinical cases, material availability and clinician preference
