| Summary: | 碩士 === 朝陽科技大學 === 營建工程系碩士班 === 98 === Modern people are usually obliged to face great pressure at work while construction workers not only have to face such pressure but also have to consume extensive physical strength. As a result, energy drinks (e.g. Paolyta B, Whisbih, etc.) have been favored by almost everyone in the construction industry. It can be seen both at construction sites and from TV commercials that construction workers are enthusiastic over such drinks. Nevertheless, it is an issue worth being explored to find out if having such energy drinks could substantially produce certain changes and bring some impacts to construction workers in order to enhance their productivity and boost their efficiency at work.
Based on the above issue, this study attempts to discuss physical changes after construction workers drink energy drinks and find out the psychological reasons why they particularly prefer such energy drinks. The most direct measuring method was adopted in the study. The productivity of construction workers before and after having energy drinks was measured so as to compare the recorded results and observe related differences. By doing so, we could confirm if such energy drinks could substantially improve construction workers’ productivity during operations. Painters and cement workers were the major objects being studied. The productivity of the objects before and after drinking was measured by hour. Meanwhile, the alcohol breath tester was used to observe the variations of alcohol concentration inside the objects’ bodies after drinking. Finally, surveys and interviews were carried out to find out what construction workers know about energy drinks. This was to examine if construction workers realized that energy drinks were actually medicine, not a drink. It involved a moderate way of drinking instead of overdrinking. At the same time, it was to find out if having energy drinks was caused by addiction and other psychological factors or by the fact that work efficiency and productivity were practically enhanced. According to the results on productivity obtained in this study, only 2 out of 12 objects showed improved productivity after having energy drinks. The results from the surveys suggested that most workers knew energy drinks came with the problem of addiction and there was no impact on work efficiency without drinking them. In addition, they were aware that energy drinks were indeed medicine rather than a drink.
