Green computing is the emerging and growing global concern in the current era. Though the information and communication technology turned the earth into paradise, it has environmental impacts through the manufacturing, operation and disposal of computing devices. In fact, computer is the basic need of every one and using it for their own purpose but no one is recognized about the harmful effect of its use on our environment. The concept of green computing emphasizes the improvement in using the computing devices efficiently and minimizing its negative impact on human beings and environment. The one of the important concerns under green computing is the e-waste management. In order to ensure green computing, there must be appropriate mapping between environmental requirements and e-waste management strategies. In this paper Quality Function Deployment (QFD) approach is presented to tackle this issue. The proposed approach serves the purpose of prioritizing e-waste management strategies in addition to the deployment of environmental needs into the measures to be taken to ensure green computing. On the basis of the priorities, the e-waste management strategies can be implemented to achieve green computing in the organization. The proposed approach is demonstrated through a case study carried in an educational institution.

UAS with inflatable wings (UASWIW) is relatively a novel and complex arena and more to that is its certification process, which is more complex as well as challenging. This paper broadly presents a three-tier architecture to identify the potential hazards associated with UASWIW and proposes the necessary certifications required according to 14CFR. For the sake of simplicity, only a few aerodynamic potential hazards are taken into account and evaluated accordingly. The proposed analytic approach completely satisfies the rules and guidelines controlled by the Federal Aviation Administration (FAA) and would prove a milestone for future researchers who wish to pursue in the same arena.

A research project was commissioned to study the influence and importance of service quality, employee loyalty, and profitability with service profit chain (SPC) model in telecom service industry in Oman. A questionnaire-based survey was conducted to investigate the consequences of a company's internal assets in terms of employees' satisfaction and loyalty, operational efficiency, and its fallout on company's turnover in terms of revenue and profitability. The telecom service chain spans three entities with service flowing from original equipment manufacturers, to telecom service providers to end users. The findings indicate that the proposed "three-tier two-stage" model holds important lessons for service industry, with service quality and human capital standing out prominently. Next, the employees' loyalty should be seen as valuable assets in an organization in order to improve company's internal performance and develop better relationships with customers and suppliers. Therefore, service quality, employee loyalty and SPC attributes should be measured periodically.

Titanium and their alloys are biocompatible, corrosion resistant, good machinability, better fatigue strength and relatively low modulus of elasticity. Due to these desirable properties, they generally have cardiac and cardiovascular applications. For modern clinical requirements a proper tailoring of these materials can be done by surface modifications. This article gives a general perspective of surface modifications of titanium and its alloys. By allowing surface modifications of titanium and its alloys, properties of these materials can be changed in order to improve their biomedical applications.

The Industrial Revolution, which started with the invention of the steam machine in 1778 by James Watt, brought along the 4th and 5th Industrial Revolutions with the development of information and communication technologies in the 21st century. With the 4th Industrial Revolution announced by Germany in 2011; The idea of integrating industrial processes with information communication technologies, IoT, sensors, artificial intelligence, and robotic solutions has changed with the Society 5.0 concept announced by Japan in 2016. The most important aspect of the Society 5.0 concept that distinguishes it from the Industry 4.0 concept is; The concept of Society 5.0 puts human and human needs at its focal point. The concept of Total Quality Management (TQM) is a management philosophy that has played an important role in the development of many countries in the world, especially Japan and America, and the industrial sector since the second half of the 20th century However, as in every approach and system, TQM has been affected by the changes in both technology and the business world over time. The developments experienced caused the restructuring of TQM. Within the scope of this study, a theoretical study was carried out on what kind of effects Society 5.0 might have on TQM strategies and the concept of Social Quality have introduced.

This study assessed the relative importance and relationships of the project management practices of construction companies in Nigeria. A total of 221 valid responses were received from the respondents from 250 questionnaire survey carried out on their professional certifications and the level of usage of fifty-three identified project management practices. The result of the data analyses in SPSS (statistical package for social sciences) and LISREL (linear structural relationship) indicates that only 22% of the respondents have at least a certification in project management which implies a poor level of skillfulness in the utilization of project management tools, methods and techniques in managing projects. Also, the respondents agreed that the utilization of project management practices enhance project management as indicated by the above average value of their relative importance. However, it was found out that there was poor utilization of the tools relating to budget management as indicated by the below average value of the relative importance index. The SEM model indicates that communication management positively influences the other project management practices with the highest level of impact on procurement management. It also indicates that cost management negatively influences quality management which implies that excessive control of project cost could result to a compromise in the quality of the output. These findings calls for project organizations to encourage and support the training of their professionals in project management practices and certifications.
