In this study, recognized building-related health symptoms of various workers in dental college hospitals are surveyed and analyzed in order to improve indoor environment at dental college hospitals. We conducted a questionnaire survey for 682 workers in three dental college hospitals located in Seoul from Sep. 20 to Oct. 8, 2004. Most workers at dental hospitals complained about noise, poor ventilation, dusty environment, and air dryness. SBS symptoms score for subjects was 1.43${\pm}$0.74 (often feel) and major symptoms was throat, CNS, eye, and nose symptoms. Recognized Building-related health symptoms are significantly related to tasks, working experience, job-satisfaction, indoor environment recognition index, medical history, used to special material, and number of dental unit chair. Also working places and ventilation are significantly related to the symptom. Based on the results, it can be said that special dental treatment causes undesirable environment such as noise, dust, and bad odor. It is also related to recognized building related health symptoms reported by workers at dental hospitals. So managemental efforts are needed to improve indoor environment which is related by dental treatment.

The Government is going to enforce assessment of dental institutions in addition to assessment of medical institutions so that it can provide good-quality medical service to people having much interest in quality of medical service. But the empirical research on the assessment of dental institutions which is still in a model assessment stage, is insufficient. Accordingly, the present research aims to help dental institutions preparing the main assessment by researching an acceptance level of workers of dental institutions in a process performing assessment of dental institutions, based on the preceding researches that the perceived utility has influence on implementation intention. The present research proved the influence that job relevance, result demonstration, usability and education & training of workers and manager's leadership of an infection management part affects perceived utility and implementation intention. As a research result, all the job relevance, result demonstration, usability have a positive(+) influence on perceived utility and implementation intention, and the influence of job relevance most affects especially. The leadership and education & training have influence on what workers get to have implementation intention after perception of utility of infection management according to the order. According to the above results, it can be understood that medical institutions preparing for assessment of dental institutions take charge of the assessment part having high relevance with work of workers and need to make a manager ordering performance of its assessment be able to foster a leadership for improving effectiveness of assessment performance.

Generally, X-ray examinations for dentistry use low energy radiation. It explains that the radiations are mainly absorbed to a human body because of the weak permeability. We made up some counterplans for decrease in radiation exposure, when guardians and radiologists are overexposed owing to unavoidable circumstances. The equipments for the test are GX-770 and CRANEX TOME CEPH which are used for various exams. Besides we measured the radiations in the projection room and in the control room using model 2026c and 20X6-1800. According to the test, the measurement value in the control room was low dose below $20{\mu}R$, the maximum dose in the projection room was $702.8{\mu}R$ and the measurement value of back dose was higher than lateral one. As the result, if we use a shielding door, it's effective for radioprotection and when we didn't prepare protectors, we should secure appropriate distance and be situated at the side area($90{\sim}135^{\circ}$) on the basis of centeral radiation. That way will provide valuable aid for radioprotection.

Objectives: This study was conducted to identify the correlation between belief in hand hygiene, activities and related hand hygiene performance rates among dental staff. Methods: This study was based on the evaluation of 329 dental practitioners, including dental hygienists who work at dental clinics, dental hospitals, general and university dental hospitals in Seoul, Gyeonggi-do Province, and Incheon. The questionnaire consisted of a total of 46 questions, including 7 questions on general characteristics, and 25 questions on hand hygiene beliefs, and 5 questions on hand hygiene activities, and 9 questions on hand hygiene practices. This study used 291 subjects for the final analysis, excluding subjects who had provided incomplete or inappropriate responses to the questionnaire. The collected data were analyzed using an independent t-test, ANOVA, $x^2$ test, correlation analysis, and multiple linear regression analysis, where p-values of <0.05 were considered statistically significant. Results: Longer clinical career was associated with a significant increase in behavior and norm beliefs, but no sequential difference in control beliefs. The hand hygiene performance was higher in staff at larger hospitals after contact with pollutants and contaminated environments. Higher age was associated with a significant increase in hand hygiene performance rates, but profession was not statistically significant in the performance rate of hand hygiene. The hand hygiene performance rate was ranked higher among those with average work hours per week of greater than 8 hours followed by those who worked fewer than 8 hours. Fewer work hours per week, a stronger belief in hand hygiene, less frequent exposure to contaminated environments, and a greater number of hand hygiene performance had a positive effect on higher hand hygiene performance rates. Conclusions: In order to increase the hand hygiene performance rate of dental practitioners, it is considered that required time for hand washing should be ensured sufficiently. Proper usage of hand sanitizers should also be promoted efficiently.
