Objectives : The purpose of this study was to improve the practice level on dental hygienists'infection prevention by examining the actual condition of dental hygienists'infection control and analyzing factors of having influence upon this. Methods : A questionnaire survey was carried out from July 18, 2011 to August 26 targeting dental hygienists who work at medical institutions where are located in Daegu, Busan and Ulsan Metropolitan Cities and Gyeongsangnam buk-do. After then, the following conclusions were obtained. Results : 1. As a result of surveying practice by item in the practice level of infection prevention, the items with high practice level in the management of infectious diseases were surveyed to be 12 months(89.6%) for health-checkup cycle and to be having experience of vaccination(78.0%) for hepatitis type B. The items with high practice level in the management and practice of washing hands were indicated to be in order of regularly paper towel(87.7%) and hands cleaning after regular medical examination(80.5%). In the item of the practice on wearing and managing individual protection equipment, regularly wearing(93.1%) rubber globes given washing implements was indicated to be high. 2. As a result of analyzing working career, working institution, working region, and practice level of infectious-disease management, the appearance of fulfilling infection control guidelines at medical institution and the experience of education for infection control were indicated to have difference depending on working institution. Regularly health checkup was indicated to have difference depending on respondents' working career and working institution. 3. The whole average in the practice level of infection prevention according to working career, working institution, and working region was indicated to be 2.55 out of 3-point perfection. 4. Wearing latex gloves was indicated to have statistically significant difference depending on working institution(p<0.001) and working region(p<0.001). The exchange of latex gloves every patient and the use of paper apron had statistically significant difference depending on working region(p<0.001). 5. As a result of comparing the frequency of using protection equipment for preventing infection according to the management of infectious diseases, the statistically significant difference was shown depending on the appearance of infection control guidelines at medical institution(p<0.001), the appearance of having experience of health checkup(p<0.01), and the appearance of having experience of vaccination for hepatitis type B(p<0.05). Conclusions : The above-mentioned findings showed that the denture satisfaction of the denture-wearing senior citizens was linked to their subjective oral health awareness. Therefore it will be possible to improve denture-wearing elderly people's quality of life when oral health plans geared toward boosting their denture satisfaction are carried out.

This study was undertaken to address the difficulties and inconveniences of an electric wheelchair. We focused on improving usability of initially completed products by augmenting the prototypes designed in the previous study. For evaluation of usability, 10 elderly women aged over 65 years, capable of movements and physical activities in daily life, were enrolled as subjects. The experimental method included a subjective satisfaction questionnaire evaluation of the elderly women using the target product, and the observation evaluation was achieved using video recording data, etc. Usability evaluation revealed that the elevating sector requires improvement of intuition through separation of the elevating control panel and the driving control panel. Improvements in the driving sector include corrections of the front wheel mechanism or driving control algorithm, UI, and sudden stop system. Transferring section assessment revealed a necessity to secure structures and add structures that support power. We believe that based on the inconveniences and improvements presented in the usability evaluation, appending the existing prototype with complementary products will improve the quality of life of elderly women with limited mobility.

Purpose: This study was to investigate visual performance and subjective satisfaction with multifocal soft contact lenses at near works in university students. Methods: In a cross-over study design, 26 students (6 male, 20 female) who did not have any ocular disorder with at least 20/20(1.0) binocular vision were fitted with singlevision lenses (SofLens$^{TM}59$, Bausch + Lomb Co. USA) or multifocal lenses (SofLens Multifocal, Bausch + Lomb Co. USA). After 2 weeks, visual performance assessments included visual acuity, stereoacuity and contrast sensitivity function at distance and near. Near point of accommodation, accommodative facility, near point of convergence, vergence facility and near range of clear vision at near were examined. Students' satisfaction and preference were measured using survey questionaries. Results: Subjects maintained at least 20/20 binocular vision with multifocal and single-vision lenses at distance and near. There was no difference between multifocal and single-vision lenses in stereoacuity, contrast sensitivity function and vergence facility at far and near. The near point of accommodation, accommodative facility, near point of convergence and the near range of clear vision with multifocal lenses were better than single-vision lenses. On the survey questionaries, subjects reported that they preferred and satisfied with multifocal lenses with near works, and single-vision lenses with distance works. Conclusions: The majority of university students preferred multifocal to single vision lenses because multifocal lenses provided better visual performance at near works. This study suggests that multifocal lens is helpful for young adult in prolonged near works.

In 2005, there was a partial revision of the Act on the Promotion of Education for the Handicapped people, so that students with health impairments would be able to receive special education support. Since the amendment of the bill, to support them classified into weak people in education, education support systems have been proposed and settled so that they may receive the support for free. According to the pre-study, after the amendment of this bill, there has been many studies on the form of educational service to support them, and recently, there have been a lot of researches to investigate their satisfaction with the current services and draw its problems. And yet these studies have been carried out by the preceeding researchers at the drawing of problems, but have a limitation to present fundamental countermeasures to the problems. Therefore, this study attempted to understand the meaning of health impairment through the pre-study and investigate the forms of the services currently supporting them and analyze the problem of each service. In addition, to solve the identified problems, a new support system was proposed. In order to confirm the performance of the system, we design the user satisfaction survey composed of a Likert 5-point scale per each question, and to make the task, comparing stories and clapping for increasing quality of their subjective evaluation about the image and voice transmission when the user uses it. As a result, in the overall evaluation of the robot system, the average score of each question was recorded to 4.31 points, and through the two tasks, it was found that there were effective data transmission of image and voice.

Purpose: We try to evaluate the functional outcomes of the ankle with isokinetic plantaflexion torque for acute achilles tendon rupture cases those treated by primary repair with the Krackow suture technique and early rehabilization. Materials and Method: The authors studied retrospectively, 15 patients of acute achilles tendon rupture treated and followed over six months, from July 1997 to May 2001. There were 12 men and 3 women, and mean age was 39.6year. The repair method of ruptured tendon was single or double Krackow suture technique. One week(5days-2weeks) after operation, early ROM with ankle-foot orthosis was started. We used Arner-Lindholm Scale for the clinical evaluation and analyzed patient's satisfaction and subjective strength deficit. We analyzed the dorsiflexion peak torque and plantarflexion peak torque of the ankle statistically with strength test with Cybex dynamometer. Result: In clinical results, we had 11 excellent cases(73%) and 3 good cases(20%). In patients satisfaction degree, 11 excellent cases(66.6%), 3 good cases(20%) and 2 fair cases(13.4%). And in strength deficit, 3 none deficit (20%), 9 minimal deficit(60%). We evaluated the isokinetic plantar flexion torque in 3months or 6months after operation. After 3 months, isokinetic test showed the mean functional deficits, 32% and 25% at $30^{\circ}$ and $120^{\circ}/sec$, in 7 cases(46.6%) of 15 cases respectively. After 6 months, the mean deficits were in 21%, 24% at 30. and $120^{\circ}/sec$, respectively. At 3 and 6 months' follow up, absolute value of isokinetic test showed increase of 25. 31bs to 421bs and 19.61bs to 271bs at $30^{\circ}$ and $120^{\circ}/sec$, respectively. Conclusion: We had good result for acute achilles tendon rupture treated by Krakow suture technique and early range of motion exercise of the ankle. After 6 months, strength deficit was 21% in all of cases but were able to return pre-injured state. This study shows Krakow suture technique was recommended method for primary repair and early rehabilization of achilles tendon ruptue.

Purpose: This study was performed retrospectively to evaluate clinical outcomes of distal metatarsal osteotomy using bio-compression screw as the joint preservation method for advanced hallux rigidus. Materials and Methods: Eleven cases were followed up for more than 1 year after distal metatarsal dorsal wedge osteotomy for advanced hallux rigidus. The clinical evaluation was performed according to the American Orthopaedic Foot and Ankle Society (AOFAS) score and patient's satisfaction score. The range of motion, and the period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were evaluated. As the radiographic evaluation, the interval of $1^{st}$ MTP (metatarsophalangeal) joint space and the period to union were measured. Results: The AOFAS hallux score had improved significantly from preoperative average 50.7 points to 87.6 points at the last follow-up (p=0.005). The subjective satisfaction score was average 90.6 points. There were no case of subsequent fusion or additional operation, and no complication associated with bio-compression screw. The period to return to running exercise, tip-toeing gait, squatting, walking down the stairs were average of 24.8 weeks, 20.4 weeks, 16.8 weeks, 18.5 weeks respectively. Dorsiflexion of $1^{st}$ MTP joint had improved significantly from preoperative average $17.5^{\circ}$ to $44^{\circ}$ (p<0.001). All cases achieved union of osteotomy site, and the period to union was average 10.4 weeks. The interval of $1^{st}$ MTP joint space had improved significantly from preoperative average 1.2 mm to 3.5 mm (p=0.014). Conclusion: Distal metatarsal osteotomy using bio-compression screw seems to be one of effective treatment methods for advanced hallux rigidus, because of restoration of the first MTP joint motion, and reliable pain relief, and needlessness of hardware removal.
