Abstract: A cross-sectional study among 15,639 Malaysian adult males aged 18 years and above was conducted using proportional to size stratified sampling method. The socio-demographic variables examined were level of education, occupation, marital status, residential area, age group and monthly household income.The prevalence of smoking among adult males in Malaysia was 46.5% (95% CI: 45.5–47.4%), which was 3% lower than a decade ago. Mean age of smoking initiation was 18.3 years, and mean number of cigarettes smoked daily was 11.3. Prevalence of smoking was highest among the Malays (55.9%) and those aged 21–30 years (59.3%). Smoking was significantly associated with level of education (no education OR 2.09 95% CI (1.67–2.60), primary school OR 1.95, 95% CI (1.65–2.30), secondary school OR 1.88, 95% CI (1.63–2.11), with tertiary education as the reference group). Marital status (divorce OR 1.67, 95% CI (1.22–2.28), with married as the reference group), ethnicity (Malay, OR 2.29, 95% CI ( 1.98–2.66; Chinese OR 1.23 95% CI (1.05–1.91), Other Bumis OR 1.75, 95% CI (1.46–2.10, others OR 1.48 95% CI (1.15–1.91), with Indian as the reference group), age group (18–20 years OR 2.36, 95% CI (1.90–2.94); 20–29 years OR 3.31 , 95% CI 2.82–3.89; 31–40 years OR 2.85 , 95% CI ( 2.47–3.28); 41–50 years OR 1.93, 95% CI (1.69–2.20) ; 51–60 years OR 1.32, 95% CI (1.15–1.51), with 60 year-old and above as the reference group) and residential area (rural OR 1.12 , 95% CI ( 1.03–1.22)) urban as reference.The prevalence of smoking among Malaysian males remained high in spite of several population interventions over the past decade. Tobacco will likely remain a primary cause of premature mortality and morbidity in Malaysia. Continuous and more comprehensive anti-smoking policy measures are needed in order to further prevent the increasing prevalence of smoking among Malaysian men, particularly those who are younger, of Malay ethnicity, less educated, reside in rural residential area and with lower
Teachers’ Creativity in Posing Statistical Problems from Discrete Data  [PDF]
Effandi Zakaria, Faridah Salleh
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.38201
Abstract: Choosing a quality problem in mathematics is a challenge for many teachers. Teachers cannot rely on textbooks for good problems. They have to be able to pose their own problems in order to promote mathematical thinking among students. This study was conducted to explore the creativity of 175 teachers in terms of fluency, flexibility, and originality in posing statistical problems. Participants consisted of secondary school teachers from twenty schools in Peninsular Malaysia. Teaching experience was ranged from 1 to 33 years. The features of the problems posed by these teachers were also studied. The participants were provided a stimulus, which was a set of ungrouped discrete data, and they were asked to pose as many problems as they could. The posed statistical problems were supposed to promote mathematical thinking and to increase students’ understanding. Findings showed that participants were able to pose a total of 270 (74%) statistical problems within the time given. The mean of the creativity score was 11.08 (s.d. = 6.76). Analysis showed no significant difference in creativity between gender and the value of t = –.346, p = .73, where p > .05. Analysis showed significant differences in the teachers’ creativity scores for three groups of teachers: F (2172) = 6.83, p = .001, p < .05.The results also showed that 115 (31.5%) posed problems focuses on the statistical content measure of central tendency. The study provided expo- sure to the teachers to pose problems that can trigger students’ thinking in solving statistical problems.
Makespan Algorithms and Heuristic for Internet-Based Collaborative Manufacturing Process Using Bottleneck Approach  [PDF]
Salleh Ahmad BAREDUAN, Sulaiman HASAN
Journal of Software Engineering and Applications (JSEA) , 2010, DOI: 10.4236/jsea.2010.31011
Abstract: This paper presents makespan algorithms and scheduling heuristic for an Internet-based collaborative design and manufacturing process using bottleneck approach. The collaborative manufacturing process resembles a permutation re-entrant flow shop environment with four machines executing the process routing of M1,M2,M3,M4,M3,M4 in which the combination of the last three processes of M4,M3,M4 has high tendency of exhibiting dominant machine character-istic. It was shown that using bottleneck-based analysis, effective makespan algorithms and constructive heuristic can be developed to solve for near-optimal scheduling sequence. At strong machine dominance level and medium to large job numbers, this heuristic shows better makespan performance compared to the NEH.
Fuzzy Soft Expert Set and Its Application  [PDF]
Shawkat Alkhazaleh, Abdul Razak Salleh
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.59127

In 1999, Molodtsov introduced the concept of soft set theory as a general mathematical tool for dealing with uncertainty. Alkhazaleh and Salleh (2011) define the concept of soft expert sets where the user can know the opinion of all experts in one model and give an application of this concept in decision making problem. So in this paper, we generalize the concept of a soft expert set to fuzzy soft expert set, which will be more effective and useful. We also define its basic operations, namely complement, union, intersection, AND and OR. We give an application of this concept in decision making problem. Finally, we study a mapping on fuzzy soft expert classes and its properties.

Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.914172
Abstract: This paper discusses a proposed instruction model for intervention of social skills children with visual impairment. Intervention model based on Badura’s Social Cognitive Learning Theory were?proposed to help students with visual impairment in the development of their social skills. The emphasis of the theory was based on imitation, environment and cognition. The three elements are interrelated in the development of social skills and individual behavior. The theory stressed the process of learning behavior through imitation. Without visual information, the imitation was learnt from the information through hearing and touch as well as physical model. The process of imitation was received with reward, reinforcement and motivation will strengthen the social skills learned and the target behavior. In addition, teachers, parents and the communities have an important role in helping and training the visually impaired children to improve their social skills. The impact of the proposed intervention model, the social skill of visual impairment children?will be improved so that they can?be?socialized effectively with typical children.

Further insights into the syndrome of prolapsing non-coronary aortic cusp and ventricular septal defect
Akhlaque N Bhat,Ahmad Sallehuddin,Mohammad Riyas,Reyaz Ahmad Lone
Global Cardiology Science & Practice , 2012, DOI: 10.5339/gcsp.2013.11
Abstract: Ventricular septal defect ( VSD ) with prolapse of the right coronary cusp and aortic regurgitation can be managed surgically with the anatomical correction technique . However when the VSD is located underneath the non coronary cusp surgical management differs due to anatomical constraints and secondary pathological changes seen in the non coronary cusp. It is therefore important that the location of the VSD and the morphology of prolapsing cusp be characterised preoperatively in order to plan appropriate surgical repair. We present a case study in which we discuss the salient differences in the surgical management of the prolapsing right and the prolapsing non coronary cusps.

Journal of Water Resource and Protection (JWARP) , 2010, DOI: 10.4236/jwarp.2010.23030
Abstract: This study focused on developing an efficient and cost effective processing technique for Moringa oleifera seeds to produce natural coagulant for use in drinking water treatment. The produced natural coagulant can be used as an alternative to aluminum sulphate and other coagulants and used worldwide for water treatment. This study investigates processing Moringa oleifera seeds to concentrate the bio-active constituents which have coagulation activity. Moringa oleifera seeds were processed for oil extraction using electro thermal soxhlet. Isolation and purification of bio-active constituents using chromatography technique were used to determine the molecular weight of the bio-active constituents. The molecular weight of bio-active constitu-ents found to be in a low molecular weight range of between 1000 – 6500 Dalton. The proposed method to isolate and purify the bio-active constituents was the cross flow filtration method, which produced the natu-ral coagulant with very simple technique (oil extraction; salt extraction; and microfiltration through 0.45 µm). The turbidity removal was up to 96.23 % using 0.4 mg/L of processed Moringa oleifera seeds to treat low initial turbidity river water between 34-36 Nephelometric Turbidity Units (NTU) without any additives. The microfiltration method is considered to be a practical method which needs no chemicals to be added com-pared to other researchers proposed methods. The natural coagulant produced was used with low dosages to get high turbidity removal which considered to be a breakthrough in this study and recommended to be scaled up for industry level. The product is commercially valuable at the same time it is minimizing the cost of water treatment.
