Framework of Six Sigma implementation analysis on SMEs in Malaysia for information technology services, products and processes

For the past two decades, the majority of Malaysia’s IT companies have been widely adopting a Quality Assurance (QA) approach as a basis for self-improvement and internal-assessment in IT project management. Quality Control (QC) is a comprehensive top-down observation approach used to fulfill requirements for quality outputs which focuses on the aspect of process outputs evaluation. However in the Malaysian context, QC and combination of QA and QC as a means of quality improvement approaches have not received significant attention. This research study aims to explore the possibility of integrating QC and QA+QC approaches through Six Sigma quality management standard to provide tangible and measureable business results by continuous process improvement to boost customer satisfactions. The research project adopted an exploratory case study approach on three Malaysian IT companies in the business area of IT Process, IT Service and IT Product. Semi-structured interviews, online surveys, self-administered questionnaires, job observations, document analysis and on-the-job-training are amongst the methodologies employed in these case studies. These collected data and viewpoints along with findings from an extensive literature review were used to benchmark quality improvement initiatives, best practices and to develop a Six Sigma framework for the context of the SMEs in the Malaysian IT industry. This research project contributed to both the theory and practice of implementing and integrating Six Sigma in IT products, services and processes. The newly developed framework has been proven capable of providing a general and fundamental start-up decision by demonstrating how a company with and without formal QIM can be integrated and implemented with Six Sigma practices to close the variation gap between QA and QC. This framework also takes into consideration those companies with an existing QIM for a new face-lift migration without having to drop their existing QIM. This can be achieved by integrating a new QIM which addresses most weaknesses of the current QIM while retaining most of the current business routine strengths. This framework explored how Six Sigma can be expanded and extended to include secondary external factors that are critical to successful QIM implementation. A vital segment emphasizes Six Sigma as a QA+QC approach in IT processes; and the ability to properly manage IT processes will result in overall performance improvement to IT Products and IT Services. The developed Six Sigma implementation framework can serve as a baseline for SMEs to better manage, control and track business performance and product quality; and at the same time creates clearer insights and un-biased views of Six Sigma implementation onto the IT industries to drive towards operational excellence

Using Fine-Grained Sediment and Wave Attenuation as a New Measure for Evaluating the Efficacy of Offshore Breakwaters in Stabilizing an Eroded Muddy Coast: Insights from Ca Mau, the Mekong Delta of Vietnam

Offshore breakwaters can be effective in reducing the energy of incident waves through dissipation, refraction or reflection. Breakwaters are increasingly constructed to stabilize eroded muddy coasts, particularly in developing countries. Accumulation of fine-grained sediment and wave attenuation are two attributes of a stable muddy coast. Effective interventions in stabilizing eroded muddy coasts include two important elements: accumulation of fine-grained sediment and wave reduction. The efficacy of offshore breakwaters in stabilizing eroded muddy coasts is, however, not yet adequately understood. A crucial question needing attention is whether accumulation of fine-grained sediment and wave attenuation should be used in evaluating the efficacy of these offshore breakwaters in stabilizing eroded muddy coasts. To address this issue, a pile-rock offshore breakwater in Huong Mai, Tieu Dua of Ca Mau, Vietnam was selected as an appropriate example in this regard. Accumulation of fine-grained sediment and wave attenuation were tested as means to investigate the efficacy of the Huong Mai structure in stabilizing the eroded muddy coast. The study was undertaken using field-based measurements and semi-structured interviews in three stages between October 2016 and December 2020. We found that this structure has had limited efficacy in stabilizing the eroded muddy coast. The structure was effective in dissipating the energy of incident waves, but we found no evidence of fine-grained sediment accumulation due to an inappropriate structural design. There was also no monitoring system in place, leading to difficulties in evaluating its efficacy in terms of wave attenuation and accumulation of fine-grained sediment. The gaps between the shoreline and the structure have not been adequately explained, resulting in substantial challenges in replicating the structure elsewhere. The Huong Mai structure should be strengthened using supplementary measures and granulometric tests in order to improve the efficacy in stabilizing eroded muddy coasts. The methods in this study provide new insights in this regard

FPGA based remote code integrity verification of programs in distributed embedded systems

The explosive growth of networked embedded systems has made ubiquitous and pervasive computing a reality. However, there are still a number of new challenges to its widespread adoption that include scalability, availability, and, especially, security of software. Among the different challenges in software security, the problem of remote-code integrity verification is still waiting for efficient solutions. This paper proposes the use of reconfigurable computing to build a consistent architecture for generation of attestations (proofs) of code integrity for an executing program as well as to deliver them to the designated verification entity. Remote dynamic update of reconfigurable devices is also exploited to increase the complexity of mounting attacks in a real-word environment. The proposed solution perfectly fits embedded devices that are nowadays commonly equipped with reconfigurable hardware components that are exploited to solve different computational problems

INTEGRATED HOME SURVEILLANCE SYSTEM (IHSS) via SMS TECHNOLOGY

There has been a rise in the home breaks in Malaysia. Recent statistics shows 27000 cases of home break in have been reported in the year 2006. Most of the victims reported were from the middle class residents. Although people are starting to realize the importance of home security systems yet many are reluctant to equip their home with one. On the other hand, the high class residents are always finding ways to better secure their homes due to their social background as well as their financial background. Threats have been always significant in their daily life, which leads them to secure their homes. Threats are also there to the middle class residents where a survey conducted on 50 Universiti Teknologi PETRONAS undergraduates from middle class family with their parents' combined salary between RM 3500 to RM 4000, proves this point. The survey was conducted to understand the factors that prevent the middle class residents in equipping their home with security system. The survey results show that there are three factors that contribute to the hesitation of middle class residents to secure their home with any form of security system; the implementation costs, post implementation costs and complexity of the security system which needs the home owner to have some level of technical knowledge. The objective of this project is to create home security system that is affordable, efficient, technologically sophisticated yet requires minimal technical knowledge in implementing the system. The proposed solution, the Integrated Home Surveillance System (IHSS) is designed to provide a security system that suits the middle class home owners

Management of an Urban Stormwater System Using Projected Future Scenarios of Climate Models: A Watershed-Based Modeling Approach

Anticipating a proper management needs for urban stormwater due to climate change is becoming a critical concern to water resources managers. In an effort to identify best management practices and understand the probable future climate scenarios, this study used high-resolution climate model data in conjunction with advanced statistical methods and computer simulation. Climate model data from the North American Regional Climate Change Assessment Program (NARCCAP) were used to calculate the design storm depths for the Gowan Watershed of Las Vegas Valley, Nevada. The Storm Water Management Model (SWMM), developed by the Environmental Protection Agency (EPA), was used for hydrological modeling. Two low-impact development techniques – Permeable Pavement and Green Roof – were implemented in the EPA SWMM hydrological modeling to attenuate excess surface runoff that was induced by climate change. The method adopted in this study was effective in mitigating the challenges in managing changes in urban stormwater amounts due to climate change

Study of Alternative Methods of Managing Dental Contract Health Services

There are differences in the scope of dental fudiciary services provided by Blue Cross/Blue Shield (BC/BS) carriers, the for-profit dental insurance companies, and Delta Dental Plans. The objectives of this study are: 1) to evaluate a sample of dental third party administrators (TPAs) capable of managing a national contract for management of Indian Health Service (IHS) dental Contract Health Services (CHS); 2) to evaluate options for IHS Areas and service facilities to manage the dental CHS program; 3) to document requirements of P.L. 93-638 tribes and tribal organizations with regard to management of dental CHS programs; 4) to develop a scope of work (SOW) for a national TPA contract to manage reimbursement for IHS dental CHS resources; 5) to develop a model SOW for FI contracts to manage reimbursement for tribally-managed Dental CHS services; and 6) to develop a model Provider Agreement to facilitate contracting for dental services and assure the delivery of quality services and standards. This project was a case study with interviews of key informants in a variety of organizations including: 1) TPAs; 2) IHS Area Offices and Service Units; and 3) tribes operating dental programs under P.L. 93-638 contracts with IHS. Site visits were made to BC/BS organizations in New Mexico and Michigan; Delta Dental Plans in California, Michigan, and Oklahoma; IHS Area offices and IHS and tribally-managed facilities in Albuquerque, Bemidji, California, Navajo, Oklahoma, and Portland Areas.The results indicated that the TPAs are generally strong in the areas studied: 1) administration and management; 2) claims processing; and 3) quality assurance. The TPAs often provide services that cannot be duplicated by IHS. It seems likely many TPAs would respond to an RFP to provide management and FI services for the IHS dental program. Quality assurance and data systems supporting dental CHR are uneven across IHS Areas. The study revealed four major problem area with Tribal Dental CHS: 1) inadequate information and reporting systems; 2) inadequate documentation of program procedures and associated dependence on individual program managers; 3) inadequate support for contracting and negotiating costs with local providers; and 4) a potential for fraud and abuse.Recommendations are provided in the areas of: 1) national fiscal intermediary contract; 2) valid uses of dental CHS resources; 3) dental CHS budget; 4) provider agreements; 5) quality assurance and appropriateness of care; and 6) tribal participation in fiscal intermediary contract

Alternative sweetener from curculigo fruits

This study gives an overview on the advantages of Curculigo Latifolia as an alternative sweetener and a health product. The purpose of this research is to provide another option to the people who suffer from diabetes. In this research, Curculigo Latifolia was chosen, due to its unique properties and widely known species in Malaysia. In order to obtain the sweet protein from the fruit, it must go through a couple of procedures. First we harvested the fruits from the Curculigo trees that grow wildly in the garden. Next, the Curculigo fruits were dried in the oven at 50 0C for 3 days. Finally, the dried fruits were blended in order to get a fine powder. Curculin is a sweet protein with a taste-modifying activity of converting sourness to sweetness. The curculin content from the sample shown are directly proportional to the mass of the Curculigo fine powder. While the FTIR result shows that the sample spectrum at peak 1634 cm–1 contains secondary amines. At peak 3307 cm–1 contains alkynes

Port Sustainability Management System for Smaller Ports in Cornwall and Devon

Many smaller ports in Cornwall and Devon (CAD) are situated in environmentally sensitive habitats and generate benefits for stakeholders and local communities. Such ports are often embedded in tourist based economies. Increasing environmental legislation is placing a strain on the resources of smaller ports making compliance a threat to profitability and thus the future of some ports and local economies. Over-reliance on environmental management systems (EMS) across the ports industry has predominated over the importance of holistic sustainability. This project develops and disseminates a port sustainability management system (PSMS) in CAD, assisting ports to plan marine and maritime operations more sustainably, to facilitate mitigation of potential risks, to increase knowledge and awareness of port sustainability, and to promote the adoption of a proactive stance towards sustainable port management. A constructivist philosophy suited a multiple methods research design which included ethnographic content analysis (ECA), statistical verification of qualitative coding, nine scoping interviews, and eight semi-structured interviews during the main phase of data collection. The seven Harbour Masters (HMs) in this phase represented all port governance types found in the UK. Charmaz’s grounded theory (GT) methodology guided the collection and analysis of primary data between August 2012 and February 2013 to create new theory using an inductive constructivist approach. Validation by fifteen of the thirty local HMs during industry testing revealed numerous advantages and benefits of deploying PSMS which is estimated to generate £50,000 worth of benefits per port annually, and £3,865,005 for the 15 participating ports over 5 years. A new model of smaller port sustainability has emerged. PSMS has eleven pillars of sustainability which underpin the spectrum of port operations. Within this model, each pillar is equally important in contributing to the overall sustainability of a port, and neglect of one could jeopardise sustainability overall and potentially cause a chain reaction with other pillars.European Social Fund Combined Universities of Cornwall (ESF-CUC
