Sustaining cost performance through TPM approach: A study of manufacturing organizations in Malaysia

Manufacturing companies need to respond quickly to ensure smooth daily operations and manage adjustments to uncertainties in the market place. In manufacturing companies the pressure to ensure equipment operates without breakdowns, stoppages, failures and so forth has become a major concern for maintenance staff (Carannante, Haigh & Morris,1996). The failure of equipments or machines to produce products on time as required can reflect the inefficiency in operations thus, failure to deliver quality products to the customers on time. Total productive maintenance (TPM) put more importance on total employee involvement in the maintenance activities. This paper discusses the findings of a study on TPM practices among Malaysian manufacturing companies. More than 1000 questionnaires were sent out to investigate the extent of TPM practices in Malaysian manufacturing companies and to study the relationship of TPM practices and performance. An analysis was carried out and the results show there are no differences between the TPM practices and size of companies. No differences also found in the TPM practices and certified quality management system companies. There were significant relationships between TPM practices and cost performance

Total productive maintenance and performance: A Malaysian SME experience

The importance of maintenance has been emphasized especially in the manufacturing environment. The failure of equipments or machines to produce products on time as required can reflect the inefficiency in operations thus, failure to deliver the products to the customers. The objective of TPM is to create an active participation of all employees in maintenance and production functions, including the operators who operate the machines and equipments. This paper discusses part of a preliminary study finding focusing on two main TPM practices namely autonomous maintenance and planned maintenance in a Malaysian SME. The results suggest important aspects of autonomous maintenance and planned maintenance activities that contributed to the improvement in quality and cost

Sustaining landscape condition through planned maintenance: Findings from a survey in a Malaysian local authority

Malaysia is seriously embarking on its beautification programme.Landscaping condition are being emphasized especially in the Local Authorities areas.The rapid growth of a town depends on the urban landscape that could contribute to the urbanization balance development. As more new towns and urban areas are developed and more money is spent on landscapes, the need to find a mechanism that responds to these issues is becoming urgent.Landscape in urban area refers to garden, green corridor, clearing space, plain, field in urban that used by township to exercise or walk This paper highlights the perceived satisfaction on landscape condition in a local government agency in Peninsular Malaysia.The aim of this study is as a reference for local authotities to manage their landscape condition base on public response towards their satisfaction.There were 169 involved in the survey. The data was analyze using Statistical Package for Social Science (SPSS) Ver 17.0. The findings of the research confirm that landscape maintenance success drivers have a significant relationship with perceived satisfaction on maintenance of landscape condition

Neuroma of a double gallbladder: a case report

We report a case of 55 year old male patient who presented with recurrent upper abdominal pain following a laparoscopic cholecystectomy. A subsequent diagnostic laparoscopy revealed the presence of a second gallbladder which was initially missed. The peculiarity of his symptoms can in part be explained by the presence of a traumatic neuroma in his second gallbladder. A subsequent cholecystectomy led to a complete resolution of this patient's signs and symptoms. As far as we know this is the first report in the literature of a traumatic neuroma in a second gallbladder

Aerodynamics of harmonically oscillating aerofoil at low Reynolds number

Two-dimensional flows over harmonically oscillating symmetrical aerofoil at reduced frequency of 0.1 were investigated for a Reynolds number of 135,000, with focus on the unsteady aerodynamic forces, pressure and vortex dynamics at post-stall angles of attack. Numerical simulations using ANSYS® FLUENT CFD solver, validated by wind tunnel experiment, were performed to study the method of sliding mesh employed to control the wing oscillation. The transport of flow was solved using incompressible, unsteady Reynolds-Averaged Navier-Stokes equations. The 2-equation k-ε realizable turbulence model was used as turbulence closure. At large angle of attack, complex flows structure developed on the upper surface of the aerofoil induced vortex shedding from the activity of separated flows and interaction of the leading edge vortex with the trailing edge one. This interaction at some stage promotes the generation of lift force and delays the static stall. In this investigation, it was found that the sliding mesh method combined with the k-ε realizable turbulence model provides better aerodynamic loads predictions compared to the methods reported in literature

Bisphenol a removal by adsorption using waste biomass: isotherm and kinetic studies

BPA is categorized as a new emerging pollutant that mimics the structure and function of hormone estrogen for humans and animals. The removal of BPA had been concerned because human exposure toward BPA is widespread, and it is harmful to humans and the ecosystem. The aim of the study was to remove BPA by adsorption technique and understand the application of agricultural waste material as potential adsorbent. The increasing of the surface area of post-adsorption from 4.80 m2/g to 5.83 m2/g indicated that the sulphuric acid treatment responsible for the growth in the porosity of the banana bunches, increase the number of available binding sites and its ion-adsorption capacity. The highest removal of BPA by the banana bunch and coconut bunch was obtained in the following condition: the temperature at 25°, pH 3, dosage at 100 mg, and agitation at 150rpm. The adsorption process was well described with the Langmuir isotherm, while the best correlation with the kinetic study of BPA adsorption was the pseudo-second-order model. The negative values of ΔH° suggested that the adsorption of BPA onto banana bunch (-13.748 J mol−1) and coconut bunch (-5693.67 J mol−1) is exothermic in nature

Utilisation of an operative difficulty grading scale for laparoscopic cholecystectomy

Background A reliable system for grading operative difficulty of laparoscopic cholecystectomy would standardise description of findings and reporting of outcomes. The aim of this study was to validate a difficulty grading system (Nassar scale), testing its applicability and consistency in two large prospective datasets. Methods Patient and disease-related variables and 30-day outcomes were identified in two prospective cholecystectomy databases: the multi-centre prospective cohort of 8820 patients from the recent CholeS Study and the single-surgeon series containing 4089 patients. Operative data and patient outcomes were correlated with Nassar operative difficultly scale, using Kendall’s tau for dichotomous variables, or Jonckheere–Terpstra tests for continuous variables. A ROC curve analysis was performed, to quantify the predictive accuracy of the scale for each outcome, with continuous outcomes dichotomised, prior to analysis. Results A higher operative difficulty grade was consistently associated with worse outcomes for the patients in both the reference and CholeS cohorts. The median length of stay increased from 0 to 4 days, and the 30-day complication rate from 7.6 to 24.4% as the difficulty grade increased from 1 to 4/5 (both p < 0.001). In the CholeS cohort, a higher difficulty grade was found to be most strongly associated with conversion to open and 30-day mortality (AUROC = 0.903, 0.822, respectively). On multivariable analysis, the Nassar operative difficultly scale was found to be a significant independent predictor of operative duration, conversion to open surgery, 30-day complications and 30-day reintervention (all p < 0.001). Conclusion We have shown that an operative difficulty scale can standardise the description of operative findings by multiple grades of surgeons to facilitate audit, training assessment and research. It provides a tool for reporting operative findings, disease severity and technical difficulty and can be utilised in future research to reliably compare outcomes according to case mix and intra-operative difficulty

Outcomes of obstructed abdominal wall hernia: results from the UK national small bowel obstruction audit

Background: Abdominal wall hernia is a common surgical condition. Patients may present in an emergency with bowel obstruction, incarceration or strangulation. Small bowel obstruction (SBO) is a serious surgical condition associated with significant morbidity. The aim of this study was to describe current management and outcomes of patients with obstructed hernia in the UK as identified in the National Audit of Small Bowel Obstruction (NASBO). Methods: NASBO collated data on adults treated for SBO at 131 UK hospitals between January and March 2017. Those with obstruction due to abdominal wall hernia were included in this study. Demographics, co-morbidity, imaging, operative treatment, and in-hospital outcomes were recorded. Modelling for factors associated with mortality and complications was undertaken using Cox proportional hazards and multivariable regression modelling. Results: NASBO included 2341 patients, of whom 415 (17·7 per cent) had SBO due to hernia. Surgery was performed in 312 (75·2 per cent) of the 415 patients; small bowel resection was required in 198 (63·5 per cent) of these operations. Non-operative management was reported in 35 (54 per cent) of 65 patients with a parastomal hernia and in 34 (32·1 per cent) of 106 patients with an incisional hernia. The in-hospital mortality rate was 9·4 per cent (39 of 415), and was highest in patients with a groin hernia (11·1 per cent, 17 of 153). Complications were common, including lower respiratory tract infection in 16·3 per cent of patients with a groin hernia. Increased age was associated with an increased risk of death (hazard ratio 1·05, 95 per cent c.i. 1·01 to 1·10; P = 0·009) and complications (odds ratio 1·05, 95 per cent c.i. 1·02 to 1·09; P = 0·001). Conclusion: NASBO has highlighted poor outcomes for patients with SBO due to hernia, highlighting the need for quality improvement initiatives in this group
