Effects of physical attributes of workstation enclosures on the performance of office workers with different difficult levels of office tasks and moods are presented. Performance scores in complex tasks were expected to increase with greater workstation enclosures while those in simple tasks would be the same. Mood ratings were expected to be higher in lower workstation enclosures. Performance of 102 college students on ambient office sounds (45 dBA) with office tasks were measured for 100 minutes under three different workplace enclosures: (1) four foot partitions on two sides; (2) six foot partitions on three sides; and (3) a fully enclosed workstation with eight foot partitions. The tasks were to memorize a paragraph with 130 words (complex task) and to search phone numbers (simple task). The complex task performance in the fully enclosed workstation was increased compared to that in the workstation with four foot partitions (p < 0.001) and to that in the workstation with six foot partitions (p < 0.05). However, occupants in the fully enclosed workstation with office sounds without speech generally gave higher mood ratings. It indicates that closed individual offices may offer important contributions to collaborative work as well as individual productivity. These findings would help design community revise open plan design to increase collaboration among office workers.

The purpose of this study was to compare the anthropometry, serum lipid levels, dietary behavior and health-related behaviors of shipbuilding workers. The education level was significantly higher in office workers than laborers, while age, monthly income and working years were not significantly different between both groups. The serum triglyceride, glucose concentration and AI were significantly higher in office workers than in laborers, but the serum LDL-cholesterol and HDL-cholesterol concentrations were significantly higher in laborers than in office workers. The frequency of breakfast and coffee intake was significantly higher in office workers than in laborers. In the office workers, age was positively correlated with systolic blood pressure but was negatively correlated with hemoglobin and hematocrit concentration In the laborers, working year was negatively correlated with hemoglobin, total cholesterol and serum LDL-cholesterol concentrations. Exercise was negatively correlated with total cholesterol concentration, triglyceride and LDL-cholesterol concentration and AI in the office workers. The results of this study showed that office workers are more prone to related chronic degenerative diseases. Therefore, nutritional education for the provention of chronic degenerative diseases of shipbuilding workers needs to be more focused on improving the health status of office workers.

The purpose of this study is to assess the characteristics of self-reported symptoms of workers in office building with HVAC system, and also to provide better workplaces in terms of comfort and health. The methods employed in this study include literature review, field observations, and survey. The self-reported symptoms of workers such as headache, fatigue, itching and dryness regarded as SBS symptoms commonly occur after around 3:00 pm and are relieved after leaving their office buildings. according to results in previous studies, above are possibly related to CO2 concentrations. It is also found work environment factors and the satisfaction on indoor environment are all associated with worker's health. Hopefully, this overview of current work environments concerning the level of satisfaction and health problems of workers would help create healthier indoor environment.

The purpose of this study was to examine the current office work environment and suggest the needs for improvement the quality and efficiency of work. To fulfill this task, information describing various environmental conditions was gathered from generally large offices in Pusan and Major cities in Kyoungnam. Data were collected on questionnaire's general information, lighting, air quality, temperature, health problems, noise and equipment arrangements, and the size fo workspace. The extent to which the attitudes and behaviors of workers were related to these environmental conditions was then examined and scrutinized. According to the development of office automation, the interest in improvement of office environment become increased. Workstation size, individual environmental control, health care, adequate storage space and noise control should be recognized as critical to the worker's environmental satisfactiov. Finally, based on the results of this study, a number ofrecommendations can be made for alleviating some of the problems that have been identified. Designers should be interested in knowing if their environments actually function in the manner in which they were intended.

The stress from the office environment comes from the most psychological things. Therefore, the purpose of this study is to research the psychological effect of natural element for office worker's psychological stability. This study is focused on the light, sound, air, temperature, plant, and water. Perception of these natural elements through the senses of sight, auditory, smell, and touch is effect on human body and mind directly. The application of natural elements provide a health of office workers. The result will show that, with application of the natural element, the rest space will be more powerful for health of workers. And also combination of natural element and geometric pattern will be very useful to prepare healing environment on the rest space

Water quality sampling surveys and continuous measurement of flow were conducted to identify wastewater flow characteristics for representative catchment of O and M treatment basins in A city. For HS-1 station representing commercial area, wastewater flow rises in the beginning of office-working hours, moves up and down within narrow range, and lasts till office-leaving hour, and falls gradually reflecting worker's returning home. However, in HS-2 station representing residential area, wastewater flow has two peaks, which are before office-going hour and after office-leaving hour. In residential area, the flow rate of weekends is higher than that of weekdays because it reflects population, being not contributed to generate wastewater during the working hours of weekdays, stay home and produce wastewater for weekends period. To determine the priority for rehabilitation of sewer system, infiltration rate was computed by dividing infiltration flow by mean diameter and total length of sewer, and HS-1 station ranked the first.

Objective: In this review we discuss the health effects among office workers. Background: Even if office workers are not exposed hazardous or harmful environment frequently, some problems could be happened to the office workers. Although serious occupational diseases rarely occur to the office workers, it is important to consider occupational risk factors for the office worker because the portion of the office workers is relatively high in all industries. Method: We divided possible health effects for the office workers into three categories; musculoskeletal disorders, indoor environment, and cerebro-cardiovascular diseases. We reviewed related articles, textbooks, and statistical materials non-systematically and described risk factors, related illnesses, and prevention strategies on each category. Results: Office workers have various musculoskeletal disorders to be intervened. By medical treatment, improving working environment, and ergonomic intervention, office workers can be prevented from musculoskeletal injuries. Poor indoor environment can cause many building-related illnesses or sick building syndrome. Although the etiology of some problems by poor indoor environment is not clear, it helps to maintain adequate humidity, temperature, and clarity of indoor air. Cerebro-cardiovascular diseases are a rising issue because office workers in Korea tend to work for a lot of time. To prevent the diseases, it is needed to work for adequate time, lengthen activity level, and manage other medical risk factors for the diseases. Conclusion: There is no distinct occupational disease for office workers. However, there are some aspects to consider the health effects of office workers and it is important to prevent the possible health problems. Application: A strategy against occupational diseases among office workers can be established by reviewing this article.
