Various studies related to obesity have been done; however, there is still a need to predict the possibility of losing obese patient’s weight based on history of his/her diet and exercise data. Therefore, this study use an obese patient as the case study. Diet and exercise data was collected using Smartwatch. This study classifies the obese patient’s level of possibility to lose weight to high (Good health), medium (Normal) and low (Poor health) from the patient's diet and exercise data. Machine learning techniques such as k-nearest neighbour and decision tree are used in this study to classify the diet and exercise data and find out the level of possibility to reduce weight. Analysis of this study shows that the decision tree provides the best accuracy for diet and exercise data where it is recorded 71.54% and 63.63% respectively. On the other hand, k-nearest neighbour shows the accuracy of 65.85% for diet and 69.32% for exercise data. The prediction results of this study can be used by the doctors and physicians to provide better advice and prescription for the obese patients.

The industry is lucrative yet challenging. Companies in this industry need to have strong and flexible production system as well as supply chain to cater for diverse customer requirements such as high mix low volume demand. The objective of this paper is to identify the challenges in managing quality effectively and efficiently in a contract-manufacturing environment. Observation and semi-structured interviews were conducted to understand and identify the operational problems in a local EMS company. The problems are then analyzed and generalized against existing quality theories. Interestingly, the findings showed that all the problems have been addressed in the quality theories some 30 years ago.

The objective of the study is to explore the state of OSS implementation among government agencies since the launch of the Malaysian Public Sector OSS Master Plan by the Government of Malaysia on July 16, 2004. Semi-structured face-to-face interviews using open-ended questions were conducted in April 2015 with ICT managers/ICT officers among the selected six government agencies in the Northern Region of Peninsular Malaysia. This study aims at investigating the usage of OSS and proprietary software, the level of OSS utilisation, the level of OSS knowledge and training of ICT and non-ICT staff, software development and acquisition model, internal OSS manpower capabilities and skills, user's perception on the advantages of OSS, user's perception on the risks of OSS, and the problems or barriers in OSS implementation. The results of interviews show that there are many problems or barriers in OSS implementation e.g. lack of internal OSS expertise, lack of OSS policy, and lack of top management support.

Managing a supply chain across company and country boundaries requires a strategic and tactic plan in order to gain the benefits of going offshore. Nonetheless, inventory plays a key variable in supply chain management and the company must apply best practice in controlling inventory at its optimum level. The objective of this study is to identify the challenges and possible solution(s) to resolve the problems in managing inventory held at offshore site located in China where high duties, taxes and scrap costs are incurred. Semi-structured interviews and observation were conducted in a multinational electronic measurement company to explore and to identify the inventory issues in the supply chain. The findings are then analyzed and generalized against the existing literature, which delivers possible solution(s) that the company may adopt.

In order to maintain competitiveness, companies need to learn how to manage and leverage on the increase of complexity in their operations. This study seeks to understand the relationship between operational complexity and operational performance of E and E industry in Malaysia. This survey-based study registered a response rate of 17.8% with 111 usable data. Partial Least Square Structural Equation Modelling (PLS-SEM) technique was applied to analyze the data. Operational complexity consists of two dimensions, namely, complicatedness and uncertainty. Meanwhile, operational performance has four dimensions of cost, quality, delivery and flexibility. Both variables are multi-dimensional and modeled as formative second order in PLS-SEM. Results of structural model reveal that operational complexity has a positive impact on operational performance which indicate that the higher the operational complexity, the better the performance. Based on Complex Adaptive System (CAS) in complexity science literature, the relationship between performance and complexity is an inverse U shape curve. This implies that, high operational complexity needs to be managed so as not to reach the threshold of a chaotic stage, which will affect performance. The finding provides insights for managers to cope with increasing operational complexity and to improve performance in the current fast-moving business environment. It also contributes to knowledge in complexity science.

Apart from low response rate, Malaysian companies are known to 'despise' participating in surveys. This paper briefly describes the background of the research; highlights issues and lessons learned before, during and after data collection to investigate the impact of operational complexity on Quality Management (QM) practice-performance relationships in Malaysia's Electrical and Electronics (E & E) manufacturing industry. Pre-data collection issues include determining population or sampling frame, sampling design and identifying targeted respondents. Issues during data collection are strategy and selection of techniques that would increase response rate. Finally, treatment of missing data is issue highlighted in post data collection. The paper concludes with insights based on lessons learned in each stage.
