Mental health is always affect the performance of an individual but has never aroused general concern among educator. Therefore, the main objective of this study was to identify the level of mental health between the engineering and non-engineering students, as well as the dominant methods being applied by the students in dealing with mental health problem. A survey has been used as the research design...
Most of entrepreneurs in software industries in Indonesia have sufficient capabilities for developing their products, but lack of managerial skills in managing business. To achieve business success, the entrepreneurs need not only technical knowledge gathered from their technical education, but also need managerial business knowledge. This paper aims at presenting an integrated competency model for...
Problem-based learning has proven to develop teamwork, problem solving skills, communication and critical thinking skills amongst learners. Due to these advantages, secondary schools in South Africa engage with problem-based events to promote the participation of learners in Science, Technology, Engineering and Mathematics (STEM). However, many schools face lack of time, lack of available funds and...
Obviously, one of the objectives in governmental organizations is increasing the productivity to an acceptable level in a dynamic environment; based on this as per upstream strategy of Iranian vision in 2020; the total productivity share in GDP in Iran must be reached to 31.3% (at least). So the first step is measuring the current situation of our organization and defining the attributes and the KPIs...
Excellence of operations can support all selected strategies. Process excellence is fundamental for companies to be able to implement a chosen strategy. Small and medium size enterprises (SMEs) in the manufacturing industry are no exception to this rule, but the framework to review their processes' maturity has not been widely examined. This study presents a maturity model developed especially for...
This study illustrates an estimation tool for software test that provides the estimated time and the cost of any sort of software test project. There are different well-recognized estimation tools for software development process [9], however, there remains a lack of standard tools for estimation of Software Test phase. Therefore, the authors developed a web base tool (www.4beats.net/tpet/) in order...
Sometimes, quality of a process can be described by a functional relationship between response variables and explanatory variables which called profile. In some situations, there is an autocorrelation structure within a profile. Most of the times in real practice there is no enough data to estimate the process parameters. In this case, we can use a self-starting control chart which does not need preliminary...
In manufacturing processes, a vector of multiple responses is often monitored to assess if the process is in-control. A multivariate Shewhart control chart is one method of monitoring the mean vector. If the chi-square statistic exceeds an upper control limit (UCL), then an out-of-control signal occurs. The average run length (ARL) is used to determine the UCL value. ARLs have been estimated under...
In statistical process control, Gamma control charts are often designed for time-between-events (TBEs) monitoring. For Gamma distribution, the traditional equal-tail probability limits lead to the problem that some out-of-control events may occur in higher probability than in-control events. To overcome this problem, Gamma control limits with known parameters are proposed based on the narrowest confidence...
It is quite common that the quality is measured by a categorical factor, which is classified into several ordinal levels. Usually, a specific multinomial distribution is utilized to characterize the counts corresponding to each level. However, it neglects the order among the factor levels and a control chart based on it may fail to achieve ideal performance. In this work, the ordinal information is...
The aim of the paper is to present the authors' novel approach to methodology for assessing the level of raters agreement (process operators, quality controllers and/or experts) and its interpretation, that is the methodology for study of reliability for qualitative characteristics. Both mathematical tools and study organizational guidelines are discussed. The method is based on the novel fuzzy similarity...
With the population ageing, it is a critical factor in the public transportation to erect a physical setting that fosters independent living. However, none of research studies designed a barrier free car seat device for supporting elderly and disabilities ingress or egress the vehicle, as well as sit to stand movement. In this present work, it applied ergonomics concept to design intelligent barrier...
The purpose of this paper is to design a tool for quantifying ergonomic level in organization and test its practical compatibility. The study has been undertaken to fill the research gap that no research has been attempted to develop an index for the evaluation of workspace in an ergonomic perspective of a manufacturing firm. An ergonomic quantification tool was designed by referring to a 15 criteria...
A reduction in the in-service life spans of Gauteng roadways, have been seen due to increases in the formation and recurrence of potholes and patch repair failures. With much attention being focused on the technical causes, human factors adding to this problem have not received the attention it requires resulting in increased cost and risk to road users and asset owners. With roadway maintenance and...
The musculoskeletal disorder is still one of the significant concerns among all work-related injuries. A great deal of research efforts had been made in developing tools that can be used in practical working environments for real time assessment of manual workloads. To perform those evaluations, the working posture analysis is required. Recently, the RGB-D camera has been considered by researchers...
The application of lean manufacturing that is so standardized gives negative aspects for a company, such as the possibility of increased mental workload of employees. The purpose of this study is to observe the relation between lean manufacturing performance and employee' mental workload. This research is conducted at an Indonesian aircraft company in division Manufacturing (DPM), Component Assembly...
The emergence of the mobile phone has created great opportunities for businesses, especially those providing services to customers. Hotels are very important to a country as they provide accommodation to travelers. Better services attract more hotel customers. With the advent of NFC, a wireless mobile technology, hotel customers can use NFC to get hotel services efficiently. Previous studies found...
Research on anthropometry deals with human physical measurement, capability and limitation. Due to various body measures of user of different cultures, gender, and geographical factors, then an understanding of anthropometry characteristics is a must. This study adopts Drillis and Contini ratio scaling method and complements the previous research by incorporating Indonesian adults [150 subjects],...
The purpose of this study was to investigate the effect of morning-night differences and sleep deprivation on situation awareness and driving performance. Twelve male students (mean of age 21.0±0.7 years old) participated in this study. They drove in following driving scenarios under three conditions: night condition, morning condition with and without sleep deprivation, on a driving simulator. Statistical...
This study investigates the difference in tactile sensory response when touching leathers under tactile-only and visuo-tactile environment. Total of 7 tactile variables for leathers were selected and utilized to investigate whether they derive significantly different tactile response by existence of visual interaction. As a result, affective variables of ‘rugged’, ‘elastic’, and ‘thick’ showed significant...
