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 surgical treatment of craniofacial disorders, using metallic internal osteofixation system has inspired an evolution with advanced operative technique and fixation devices over past two decades. As any other surgical procedures, this procedure also associates problems such as infection, palpability, loosening, and restrict craniofacial skeleton growth, which lead to undue secondary operations for removal. These problems are improved by using bioabsorbable osteofixation system. We compared the patient's subjective symptoms using bioaborbable system versus metallic osteofixation system in zygomatic bone fracture. we should take the individual steps (postoperative 2 weeks, and 1 year) in treating fractured zygoma. From August, 2001 to August, 2003, we used bioabsorbable osteofixation system in 28 patients in zygomatic fracture ($Biosorb^{TM}FX^{(R)}$) and compared 23 patients who were treated with metallic osteofixation system. There was no significant difference in the both groups in subjective symptoms and postoperative result.

This paper investigated the symptoms of taxi drivers' physical self-consciousness. As the subjects for the study, 374 taxi drivers participated in the survey for three months, and its result showed as follows:1. In the items of the physical symptoms, the eye's fatigue was indicated as a greatest complaint, and the corporate-taxi drivers showed a higher complaint rate than the owner-taxi drivers. 2. The survey also indicated that taxi drivers over 50 years old showed the highest complaining rate of eye's fatigue, shoulder pain, loins pain, and severe headache. Feelings of burning on empty stomach was the highest complaint factor in the age group between 30 and 39 years old, and pain and burning feelings in eyes in the age group between 20 and 29 years old.3.

By using Factor analysis on the variables relating to the subjective symptoms of total 56 workers, who have exposed to mixture of organic solvents at the musical instrument manufacturing plant, as experinmental group, and 70 workers, who worked in noisy working environment as control group, the study was performed. It was confirmed that the variables found in hematological figures, age specification, occupational history and physical examination have a influential factor on the subjective symptoms of both groups. It was explicated that the ratio of these to total Eigen Values showed 31.1 percent in experimental group and the control group revealed 37.7 percent.

The health symptoms assessment and urinary hippuric acid excretions of workers exposed to toluene occupationally in shoes workshops were investigated by the Questionnaire and the field monitoring. Based on the results, the acute health symptoms of workers exposed to toluene by questionnaire were fatigue(58.7%), irritation of the eyes, nose and throat(57.2%), and skin dryness(43.3%). And the complaints about workshop environment are odor, dust and noise. The mean values of urinary hippuric acid excretions in m식e and female were 1.08 $\pm$ 0.50 g/l, 1.59 $\pm$ 1.27 g/l in total workers, espectively.

Objectives : The aim of this study was to investigate the effect of musculoskeletal symptoms and job stress on the fatigability of 268 dental health care workers in Busan. Methods : A structured, self-administered questionnaire was given from Oct 1 through Oct 10, 2015. The collected data were analyzed with the SPSS 18.0 program. Results : The results were as follows. First, for musculoskeletal symptoms, job stress and fatigability, the highest scores were for low back pain (3.23), business stress (2.95) and physical fatigability (3.32), respectively. Second, physical fatigability increased with increasing myofascial pain syndrome, low back pain and business stress. Mental fatigability increased with increasing business stress, human relationships and social activities and decreasing age. Conclusions : Taking the above into consideration, this thesis suggests that there is definite influence from musculoskeletal symptoms and job stress factors on physical and mental fatigability.
