The acceptance of electronic laboratory information system (LIS) is gradually increasing in developing countries. However, the issue of time effectiveness due to computerization is less clear as there is fewer accessible information. One of the key issues for laboratorians is their indecision with LISs’ would-be effect of time on their work. A polyclinic in Ghana was in the process of implementing electronic LIS. Several of the laboratorians did not have knowledge and skill in computing and there were disagreeing views on the time effectiveness of the LIS after implementation. The management of the polyclinic laboratory was concerned to assess time advantageousness of recording data when using the electronic LIS compared with paper-based LIS. <div><br></div><div>Five randomly selected laboratorians were provided two sheets of paper with tables to document the time they spent for both paper-based and electronic LIS. Data were collected for a total of 230 records,115 electronic LIS and 115 paper-based LIS. The t-test (mean-comparison test) was computed to compare the means of both electronic and paperbased LIS times. </div><div><br></div><div>There was a statistical significant difference in the time spent between electronic and paper-based LIS. The time spent between paper-based and electronic LIS was 0.41 minutes (95% CI 0.15 to 0.66) longer than in electronic LIS. </div><div><br></div><div>LIS can be adopted in polyclinics without having significant negative impact on time spent between electronic and paper-based LIS. More time–motion studies that include laboratorians are however necessary in order to get a more complete picture of time spent between electronic and paper-based LIS. </div>

Heavy Construction

Equipment-related occupational accidents are very higher when compared to all other type occupational accidents in the worldwide. Various types and styles of many equipment are used in construction industries (construction and mining). This equipment are usually huge and heavy, so the consequences of accidents are severe. Occupational accidents related this equipment might occur due to operating faulty, carelessly and unserviceably. In this study, the causes of occupational accidents related with heavy equipment in construction workplaces are presented and cause-and-effect relationships of occupational accidents are investigated based on the statistics. Heavy equipment safety types are analysed for incident prevention by statistics. In addition, the detailed information are presented about the precautions to prevent such accidents. As a result, all stakeholders should pay attention to the use of new security technologies and to reduce human default to prevent workplace injuries depending on the equipment.

The Relationship

Herbaceous biomass will contribute significantly to meeting renewable energy goals. Harvesting equipment for hay is generally suitable for mowing, raking, and baling grasses such as switchgrass; however, there is a need for field data to better understand machine performance in energy crops. The purpose of this study was to collect field data to estimate baler field capacity, throughput, and speed. Data gathered with a Differential Global Positioning System (DGPS) unit during baling provided time-motion studies of baler productivity. Six fields were used to compare field capacity, speed, and throughput results from four round balers and one large-square baler. The results show that in-field performance of round balers is significantly affected by yield, but that the relationship can be represented with machinery management concepts, knowledge of maximum throughput, and wrap-eject time. Baler performance will be overestimated if the yield, maximum throughput, and wrap-eject time are not correctly accounted for.

Activity Areas

This ethnoarchaeological study of an Inupiat Eskimo fish camp examines the formation of activity areas through time-motion studies and the analyses of activity episodes. These observations on two adults using the site during the summer of 1982 are used as examples of how spatially discrete activity areas are shaped by behavioral processes. In this case, activity-area formation is tied to the adaptive strategies of the Inupiat Eskimo cultural system. Specific subsistence-related activities such as food processing, animal butchering, and equipment maintenance leave material residues after tasks are completed. Cognitive and adaptive aspects of the Inupiat cultural system contribute to the spatial organization of this fish camp.
