Objectives: The purpose of this study was to evaluate the perception of dental hygienists and look for ways to inform the dental hygienist correctly by investigating factors influencing the perception of dentalhygienists. Methods: The final analysis population for this study was composed of 302 adults aged 20 years or older who were living in Seoul or Gyeonggi-do. Statistical analysis of the collected data was conducted using the SPSS WIN 22.0 statistical program. Results: When factors influencing perceptions of dental hygienists were investigated, educational background beyond high school (p<0.05), educational background beyond college (p<0.001), occupation (student, p<0.05), title (dental hygienist, p<0.01), and whether dental hygienists offered comfort during treatment (yes, p<0.001) were found to exert statistically significant influence. In other words, participants with educational background beyond high school and college, student, participants who call the title dental hygienists, and participants who felt comforted by dental hygienists during treatment had better perceptions of dental hygienists. Conclusions: Based upon the results as mentioned above, It will be needed more training to enhance the skills of a dental hygienist patient response. Also participants who felt comforted by dental hygienists during treatment had better perceptions of dental hygienists. This indicates a need to devise ways to better foster the ability of dental hygienists.

This survey is made to offer the fundamental data for the establishment of practical environmental education plan based on understanding of the change of the environmental awareness of elementary school students under the longitudinal-sectional research design. In this research, the questionnaire made by Kim Jong-ki in 1988 and by Kim Hak-Bong in 1993, is amended and filled up, which is used to the 624 numbers of fifth and sixth grade students lived in Seoul, Pyungtaek and Yangjugu. This research ares are devided into 5 ares which are the environmental general, environmental pollution, living environment, environmental education and consciouness of environmental crisis to humen beings. First, it is grasped general tendency and then is compared and analyzed the level of awareness by residence, sex, grade. stsdard of living parental academic, the background variation of parental job with the status in 1988 and 1933. The results are as follows: 1) The rate of interest for environmental pollution and population is reduced but the rate of interest for animal protection is increased. 2) In spite of reinforcement of environmental education In school, the numbers of the students who became to know some information about that from the class are diminished. 3) Even if the children are aware of sewage seriousely, the numbers of the students who answer it is caused by domestic sewage are a few. 4) On the environmental education area, the various materials of the are not utilized well in a class. 5) On the environmental crisis to the human beings the rate is much increased in 1993 ttan that of 1988 environmental contamination is the important cause of the human beings' crises but now the rate is reduced again. In other variables except the environmental contamination, it is increased the that of 1993 on the war, on population it is showed a tendency of reduction. The results of this study are as follows : 1) It is supposed that the education should be done only not for the knowledge of environmental education but for the practice of that - animal breeding, field experience of the ecological destruction places. 2) The various environmental education materials such as TV, VTR are demanded to give the students proper information about that and to educate sufficently. 3) The course of fields exploration for environmental education should be prepared under cooperation of the authorities concerned. 4) It has to be groped for an epoch-making teaching method and the training and the practice of teachers in order to reform environmental pollution.

Rapid economic development and industrialization has been accompanied by an increase of energy demand and environmental pollution. The consumption of gasoline has increased totally, but decreased in use of leaded gasoline after 1988 in Korea. On the other hand, risk assessment of environmental pollutants requires reliable dose estimates. Source oriented monitoring is not providing adequate information to estimate human exposure. The Health Surveillance Project has been launched in Korea from 1980, which questioned their symptoms based on questionnaires and medical examinations for inhabitants in the vicinity of 13 industrial areas and 2 non-industrial areas. 10, 598 inhabitants living in these 15 areas had medical checkups and donated their blood f3r heavy metal analysis from 1980 to 2000 through this project. Especially lead levels in inhabitants' blood of these areas were determined and monitored. Totally 4, 967 samples in target areas were used to review the trend of blood lead level in this paper. Average lead concentrations by areas were from 15.2 to 21.0 ug/dl in 1981 and 22.3 to 34.3 ug/dl in 1988, but were 8.8 to 11.1 ug/dl in 1992 and 4.4 to 4.8 ug/dl in 1995. On the other hand, the consumption of leaded gasoline was at a peak in 1958. Blood lead level showed a very close relationship with the consumption of leaded gasoline in the change pattern(p<0.01) and showed a rapid declining trend since the use of unleaded gasoline, especially from 1988 when Seoul held the olympic games. For example, the blood lead levels were 15.2 ug/dl in 1981, 20.2 ug/dl in 1955. 24.3 ug/dl in 1988 and 3.9 ug/dl in 1993 in Yochon area. China also had monitored blood lead levels of general population. 7, 015 inhabitants living in 28 areas donated their blood far heavy metal analysis from 1981 to 1988. Average lead concentrations by areas were from 5.1 to 5.6 ug/dl before. 1984 but were form 2.8 to 11.2 ug/dl after 1984. Average lead concentration in blood showed increasing trends clearly in most of the areas. The recent policy of unleaded gasoline use for automobile will be a very beneficial policy for the management of atmospheric lead pollution & health risk assessment for the general population in China. It is recommended that it should be propelled more widely and rapidly to the entire country.

The role of free radicals in the progression of many diseases and aging has been given a great attention and total antioxidant status (TAS) has shown to be reduced with aging. The incidence of hypertension has shown to be relatively high in the aged population, and it is known to be associated with increased obesity and oxidative stress. The aim of this study was to examine the obesity indices and the total antioxidant status in hypertensive elderly (64y$\alpha$-tocopherol, $\beta$-carotene and ascorbic acid did not show their significant correlations with TAS. These results showed that the hypertensive elderly are prone to be obese and to have increased TAS. Due to unknown factors affecting TAS values, measurement of plasma TAS as a sole indicator of total antioxidant capacity is limited to fully understanding changes in the body's free radical trapping power. However, the results from the current study may suggest that hypertension and/or obesity might increase oxidative stress, followed by increased the body's total antioxidant defense system.

Objective: Because of communication difficulties, the hearing-impaired face many disadvantages throughout their lives. One of those is limited access to health care services, particularly medication service. Though they suffer from problems related to taking medication properly, there have been few studies on their actual condition of medication use in Korea. This study is to investigate any obstacles to properly taking medications and, therefore, to suggest preliminary evidence for policy measures to improve safe medication use among the hearing-impaired. Methods: Study participants consisted of hearing-impaired individuals living in Seoul. We also interviewed two sign language interpreters in order to illuminate health care state of the hearing-impaired. In-depth interview for each study participant was recorded and was translated into a written script for analysis. Results: Study participants were comprised of four women (66.6%) and two men (33.3%). There were one participants in 20's, two participants in 30's, one 40's, and two 50's. Sign language interpreters were all women. One was in her 30's and the other was in her 40's. Communication difficulties have been found to be key barrier to use medication safely. A negative image of pharmacists also hinders safe medication usage, lowering access to local pharmacy and leading discretional self-medication. This article provides pharmacists with solutions to promote adherence in this population. Conclusion: The hearing-impaired had limited access to medication-related information as well as using services in a hospital and local pharmacy due to their disability. Institutional improvement for safe medication usage among the hearing-impaired is necessary.

Electrical stimulation among several factors that influence bone remodeling has been studied by many investigators with great enthusiasm in orthodontic field. The action mechanisms of Pulsed Electromagnetic Field (PEMF) are different from those of the conventional electrode application method in that PEMF induces endogenous current in the living tissues. PEMF is known to have the healing effect in nonunion of bone and osteoporosis. It is widely used in orthopaedic scopes and the possibility of using the method in clinical orthodontics Is also conceivable. But the exact mechanisms by which the PEMF exerts its effects are not clearly understood. Therefore, the author wanted to see the effect of PEMF on five groups of rat calvarial cells obtained by sequential enzyme digestion method, and observed the changes in enzyme activation, collagen synthesis and $^3H-thymidine$ incorporation. The results were as follows: 1. Under the effect of PEMF, there were no changes in the alkaline phosphatase activity in five groups of cell populations. 2. Both the PEMF group and the PTH with PEMF group shelved no changes in acid phosphatase activities and there were no differences between two experimental groups. 3. Under the effect of PEMF, there was significant increase of collagen synthesis in the group V cell population. 4. Under the effect of PEMF, there were significant increases of $^3H-thymidine$ incorporation in the group IV and V cell populations.
