Abstract

Studies on the driver's fatigue, must focus on at least two things: the time-of-day that affect by circadian factors, and time-on-task. This paper discusses the risk level of driver fatigue, which generally have to drive in a long duration or more than 4 hours. The risk of fatigue was assessed using Fatigue Likelihood Scoring (FLS) by Transport Canada. Based on interviews with 24 inter-city bus drivers, 18 of the 24 drivers have a very high risk of fatigue that characterized by FLS scores greater than 20, while the rest have a high risk driver that characterized by FLS value greater than 10. A high risk of chronic fatigue that experienced by most of drivers caused by working hours which is more than 36 hours in a week, the duration of the shift of greater than 8 hours a day, lack of time off, the amount hours of driving at night, and the amount of time off.

From the findings then performed the identification and benchmarking study, mapping towards the successful practice at the companies. Eventually it is concluded that there is no best standard for e-procurement as the factors most affecting successful implementation are non-technical, of which this understanding will be the first step to systematically analyze the supporting factors in implementing e-procurement successfully. Therefore, e-procurement does not only improve the operational performance of the company in efficiency improvement of enterprise's supply chain management process but also provide added value for the company.

That’s why a regular project progress update has become a very important factor because it can be used by management to control the project, as well as an alert mechanism or early warning sign whether or not the project is on track or off track. This paper adopts the earned value analysis (EVA) that is used to monitor IT project progress, because EVA is a simple formula whilst able to provide a comprehensive information to support decision making.

Abstract

The city that grows unplanned usually arises because of the conurbations of a culture, such as Agora in Greek and Forum in Roman. The “unplanned” city grows in strategic places, such as around the harbor, business places, worship places, or other activity centers. The city growth due to cultural centers is usually characterized by the growth of services as the economic support of the city activities. The service center develops a community center in the form of public facilities, such as public spaces and public buildings. Western understanding about this kind of design is oriented to functional vision illustrated from several illustrations of history that developed in the world of architecture. Understanding of cosmology in typology and morphology that affect the built environment, especially the face of a city, can be described by reviewing some of the phenomena that have been developed in connection with cosmological concept that affects the embryo of market formation, ie public open spaces which became the center of city residents to the commercial, political, recreational activities, and others resulting from the interaction of community activities.
