The purpose of this study was to examine the views of dental hygiene students about the possible countermeasure of domestic hospitals for the opening of the medical market. The subjects in this study were 269 dental hygiene sophomores, juniors and seniors at two different colleges in the region of Busan. The findings of the study were as follows: The opening of the medical market and views of possible countermove, whether they agreed to that or not made a statistically significant difference to their opinions on the necessity of customer-oriented marketing strategy(p=0.023), analysis of foreign medical markets/attempt to make inroads into the markets(p<0.000) and the improvement of the quality of medical services/the diversification of the services(p=0.025). As to an intention of going to a foreign hospital, they had a statistically significantly different intention about whether to go to a foreign hospital regardless of medical bills(p<0.000), whether to consult a doctor in a foreign hospital after going to a domestic hospital first (p<0.000), whether to consider the distance between their houses and a foreign hospital(p=0.05) and whether to take considerations on the assistance of an interpreter(p=0.023). In regard to preference for foreign hospitals, American hospitals ranked first(41.9), followed by Australian hospitals(19.9) and Canadian ones(14.2).

Objectives : The authors evaluated the effects on renal function of workers chronically exposed to low-level organic solvent mixtures. Methods : The authors measured the level of urine ${\beta}2$-microglobulin(${\beta}2$-MG) and microalbumin as biochemical markers of renal function and damage in 29 male workers exposed to organic solvents for more than five years and compared their results with those of 30 male office clerks as a reference group. Results : 1. The mean values of hemoglobin, hematocrit, SGOT, SGPT, ${\gamma}$-GTP were all within normal limits and there was no significant difference, except for hemoglobin(p<0.01), between exposed and reference group. 2. The values of BUN and serum creatinine were within reference limits and there was no significant difference between exposed and reference group. 3. The difference of mean values of urine microalbumin corrected by urine creatinine were statistically significant (p<0.01), but those of urine ${\beta}2$-MG was not. 4. There were no correlation of urine hippuric acids with BUN, serum creatinine, urine microalbumin and ${\beta}2$-MG. 5. There were no significant difference of BUN, serum creatinine, urine microalbumin and ${\beta}2$-MG upon work duration. Conclusions: It is assumed that chronic low-level organic solvent exposure in these workers shows early renal dysfunction, glomerular changes. The result corresponds to previous studies showing the relationship between hydrocarbon exposure and glomerulonephritis. For evaluation of impairment on kidney tubules, we need further study using more precise markers and long-term follow-up.

To assess biological air quality, concentrations of viable airborne microbes were determined in hospital home and outdoor air from August 25 to October 18, 1990. Bacteria, fungi and thermophilic bacteria were sampled using gravitational and suctional sampling method. In bacteria groups, the Staphylococcus spp. was identified by microscopic examination and biochemical tests. Results of the study are as follows. 1. Results using the gravitational sampling method indicated that average numbers of airborne microbes in hospital home and outdoor air were 21.5, 12.2 and 17.6 CFU/plate, respectively. These levels are well within an appropriate standard of 50 CFU/plate suggested by Endo. 2. Results using the suctional sampling method indicated that total airborne microbe concentrations in hospital, home and outdoor air were 1,998, 1,363 and $1,880CFU/m^3$, respectively. All of the results were within the recommended remedial action level, $10,000CFU/m^3$ of the American Conference of Governmental Industrial Hygienists(ACGIH). 3. Concentration of thermophilic bacteria in hospital and outdoor air were 79 and $111CFU/m^3$, respectively. Thermophilic bacteria were not detected in the home air. These results were within the remedial action level, $500CFU/m^3$. 4. Concentrations of Gram negative bacilli in holpital home and outdoor air were 20.3, 23.6 and $16.8CFU/m^3$, respectively. all were within the remedial action level, $500CFU/m^3$, recommended by ACGIH. 5. Concentrations of Staphylococcus spp. in hospital, home and outdoor air were 34.8, 14.7, and $22.4CFU/m^3$. respectively. all were within the remedial action level, $75CFU/m^3$, recommended by ACGIH. The percentages of Staphylococcus spp. in total bacteria in hospital, home and outdoor air were 19.0, 10.2 and 14.5%, respectively.

This study was conducted to assess exposure to musculoskeletal disorder(MSD) risk factors in hospital personnel who performed non-routinized work tasks. A tool ("PATH-KOSHA" version) was newly revised from PATH(Posture, Activity, Tools and Handling) method and uploaded into a personal digital assistant(PDA). The version was used, on a basis of direct-observation, to collect PATH data at the 2 hospital settings in different regions. Job analysis was performed to get various information (e.g., work and rest time, task type) as well. The data collected were visually checked for data cleaning and stored for future data analysis. A total of 1,992 PATH observations were made for 37 hospital workers. Exposure levels varied across 18 items of the MSD risk factors. The highest percent time spent on non-neutral postures was 53% for wrist deviation, followed by 47%(pinch grip), 35%(trunk posture), 23%(neck posture), and 20%(shoulder/arm posture). The highest percent time spent among hand activity level(HAL) variables was 55% for HAL-cat2 (HAL: 3.3 - <6.7). The percent time of items with respect to both loads with more than 5kg and contact stress was less than 4%. Vibration was not exposed in the study workers. Different aspects were discussed for findings. The study results showed that wrist deviation was highest in percent time spent on awkward posture while HAL-cat2 was highest in hand repetition. The study suggests that distal upper extremity posture and HAL should be primarily addressed and controlled in non-routinized work including the hospital settings.

This study researched into literature materials in order to utilize basic data on job importance in dental coordinator, and analyzed questionnaire on job importance in dental coordinator for about 2 months from August and September in 2008 targeting dental hygienists and other manpower for dental hospitals & clinics where are located in D region and neighboring region. The following are the results: 1. Dental hospital & clinics where dental coordinators work were surveyed to be totally 66.9%. Dental coordinators were indicated to be 71.1% as for dental hospital$^{\circ}{\S}$clinic(women), and to be 28.4% as for a case with none. There was significant difference according to final academic degree and working place(P<.001). 2. License holders(women) for dental hygienist as dental coordinator accounted for 39.8%. The opposite case accounted for 60.2%. A case of doing duty of dental coordinator given not dental hygienist was indicated to be high. There was significant difference according to working place(p<.01). 3. The task importance on job that a dental coordinator directly performs was indicated to be averagely 3.24, thereby having been recognized to be important. 4. As for the recognition on job importance according to working-year number, it was indicated to have higher recognition on task importance in the more working-year number regarding customer management(p<.01), organization management(p<.05), and self-management(p<.01). 5. Given seeing difference in recognition on task importance according to medical institution, it was indicated to be 3.34 for dental clinic and 3.25 for dental hospital. Thus, the task importance was indicated to be slightly high in a person who works for dental clinic. There was no significant difference. In light of the above results, in order to educate dental coordinator who can successfully perform a role at dental hospital & clinic, a dental hygienist is required who is equipped with dental-clinic career rather than a person without a major. A professionally educational program for dental coordinator needs to be developed. Even in a dental coordinator's task, there is necessity for the curricular development and the specialized education.

The purpose of this study was to examine and analyze motivation of entrance into the college, knowledge prior to the entrance, satisfaction with their major, and a sense of employment after graduation among students majoring in dental hygiene at some colleges and subdivide them by grades for comparative analysis to determine the progress of changes in general characteristics, department satisfaction, and a sense of employment among students majoring in dental hygiene for the recent three years and provide basic data for improving dental hygienic education. Questionnaires were distributed to 520 students majoring in dental hygiene at some college in South Chungcheong, South Jeolla, and North Jeolla Provinces, followed by explanation of the purport of the research and the content of the questionnaire; after completion, 513 copies were used for analysis with exception of 7 copies with insincere responses. The analysis of the data examined resulted in the following conclusions: First, Changes in Department Satisfaction among Students Majoring in Dental Hygiene As for motivation of entrance into a college, less and less students chose the department of dental hygiene through recommendation by parents or seniors while more and more students chose their major due to easy employment. Less and less students obtained information on the department from a college application guidebook while more and more students obtained it through Internet. There was also a gradual increase in prior knowledge about the department and in satisfaction with their major. More and more students had no will to change their course. Second, Changes in a Sense of Employment among Students Majoring in Dental Hygiene There was a gradual decrease in the number of students who would follow friends' or their own decision in selecting workplace but an increase in the number of those who would follow their professors' opinion. There was a gradual increase in the number of students who wanted to be employed in workplace with good social perception; many students wanted to be employed in a personal dental clinic, a general hospital, or a public health center; and more and more students also wanted to be employed in a school dental health center or to become a government official or an educator.

Objectives : This research was conducted to investigate geriatric care workers' oral care, and the oral care conditions of residents of elder care facilities in relation to workers' knowledge of oral care. Methods : A survey was conducted from November 2011 to February 2012 with geriatric-care workers in elder care facilities located in Busan and other areas of Gyeongsangnam-do. Results : With regard to their oral self-care practices, 52.5% of the geriatric workers "brushed their teeth from top to bottom" and 58.1% brushed their teeth 3 times a day. Further, 52.0% did not use any oral care products, while 36.5% used Mouthrinese. The workers who brushed their teeth in their own ways or from top to bottom had significantly higher oral care knowledge scores than those who brushed from left to right (p<.05). Concerning oral hygiene care for residents, 72.6% of the geriatric workers recommended that elders visit dentists for oral care, 96.6% helped elders oral wash their teeth every day, and 54.7% used oral care products for the elders. The workers who did not recommend visits to dental clinics scored slightly higher than those who did (p<.05). Additionally, those who did not help elders oral wash their teeth scored significantly higher than those who did (p<.05). Except for oral wash to recuperated old man and recommendation of visiting the dentist, relation between oral care and knowledge about oral health and oral hygiene care is plus mutual relation. Conclusions : To manage the accuracy and quality of oral care work performed by geriatric care workers in elder care facilities, enhancing standard training and education on oral care is necessary. Providing systematic, regular education on such knowledge and practices would also be essential.
