Objectives: This study aimed to investigate the perception of dental infection-control coordinator (DICC) among dental hygienist and determine whether there is a difference in perception depending on the type of work. Methods: Dental hygienists working at the dentistry were conveniently extracted and distributed to 351 patients, and the data of 320 patients were finally analyzed. The chi-square test was conducted to determine the difference in perception of the DICC according to the type of work, and the one-way ANOVA was performed to determine the difference in the perception of DICC tasks. A p-value of <0.05 was statistically significant. Results: General hospitals and university hospitals (100%), dental hospitals (95.8%), and dental clinics (86.6%) showed the highest awareness of the need for DICC. The dental clinics had the lowest level of awareness regarding the duties of the DICC, and dental hospitals and clinics were in different areas with different levels of awareness regarding infection control-related administrative support areas (3.98-4.21 and 3.79-4.12 of 5). Conclusions: Because of a difference in perception regarding the work of DICC according to the type of work, dental organizations should establish the tasks of DICC and develop an education program for a person in charge based on this.

It is important to understand that patients with hemiplegia are under stress during the rehabilitation process. This study was designed to determine what changes occur in the stress perceived by these patients during the rehabilitation process. and what changes occur in the ways they coped with stress. A decriptive study with a longitudinal design was conducted. A total of 57 patients with hemiplegia who were admitted to one general hospital made up the sample for this study. A questionnaire, observations and interviews were used for the data collection which was done in three phases(within one week after admission : within one week before discharge ; within one month after discharge ). Data were analyzed using t-test, ANOVA repeated measures of ANOVA, and post hoc paired t -test, Bonferroni correction. The results of this study are : 1. Changes in the perception of stress during the rehabilitation process : There was a statistically significant differencs in the perception of stress among these patients during the rehabilitation process. On the post-hoc test. the perception of stress showed a statistically significant decrease from admission to discharge. The perception of psychological stress was high during the rehabilitation process as compared with the perception of physical and social stress. 2. Changes in the way the patients coped during the rehabilitation process : On admission passive coping was used by most of the subjects(91.2％). Passive coping showed an decrease from admission to discharge, but an increase from discharge to follow-up at one month post discharge. There was, however, no statistically significant changes in the way the patients coped during the rehabilitation process. 3. Changes in perception of stress during the rehabilitation process according to variables. Perception of stress among patients classified as So-Um was higher during the rehabilitation process, when compared with patients classified as So- Yang and Tae-Um. There was, however, no statistically significant difference in perception of stress over time. The patients with right sided paralysis perceived higher stress than those with left sided paralysis. There was, however, no statistically significant difference in perception of stress over time. Hence, stress was not influenced by which side was paralyzed th frequency of the relapse of the disease, or the time in the rehabilitation process. 4. Changes in coping during the rehabilitation process according to variables. There was a statistically significant difference in the way the patients coped at follow- up according to the three different kinds of the constitution groups. In other words, coping was not used by patients classified as Tae-Um but was used by those classified as So-Um. On the repeated measures of ANOVA, there was a statstically significant difference in stress over time, and an interaction between constitution and time. But the way of coping during the rehabilitation process was not influenced by which side was paralyzed nor by the frequency of the relapse of the disease. In conclusion, perception of psychological stress was high during the rehabilitation process, as compared to perception of physical and social stress. There was a statistcally significant difference in the perception of stress over time, Perception of stress showed a gradual decrease from over admission to follow-up period. There was. however, no statistically significant difference in the way of coping over time. Passive coping was used by most of patients. In the study, these findings suggest a need for nursing care related to the psychological support for patients with hemiplegia both in the hospital as well as at home, and the need for education and counseling on independent self-care to help the hemiplegic patients adapt to stress using active coping.

Purpose - The purpose of this study is to elucidate the perception differences between CEOs and employees, and to derive a plan for improving performance by using theory of planned behavior (TPB) to enhance the competitiveness of SMEs exposed to various difficulties until recently. Research design, data and methodology - A total of 238 valid questionnaires were collected for CEOs and members of SMEs. In order to clarify the difference of perception, independent sample t-test and multi-group analysis using AMOS were conducted. Simple regression analysis and structural equation were used to confirm whether the theory of planned behavior was applied at the level of SME. Results - The CEO group is more aware of company's ethical responsibility activities and organizational support than the group of employees, and collectivism contributes more to organizational development than individualism tendency. Also, the theory of planned behavior is applied to the SME level as well. Conclusion - This study suggest that CEOs need to accept the pluralism of their members for the development of SMEs. In addition, it is necessary to form a consensus on ethical responsibility activities that corporations are performing by supporting diverse strategies and members' participation in management decision-making.

This study purposed to analyze difference in the perception of service quality between physical therapy patients and physical therapists and to provide basic materials for maintaining high service quality that meets patients' expectation in each service area. For this study, we conducted a questionnaire survey with physical therapy patients and physical therapists in Jeju from the 6 to 30 of January, 2010. In the survey, we received 133 questionnaires from patients and 125 from physical therapists, and used them in analysis. The instrument used in this study to measure service quality was prepared by the researcher through adapting and supplementing the SERVQUAL model developed by Parasuraman et al (1991). For our physical therapy environment, and it consisted of a total of 23 questions in five areas, namely, tangibility, reliability, responsiveness, assurance, and empathy. Patients' perception of service quality was high in order of reliability, assurance, empathy, responsiveness, and tangibility. In four areas with exception of reliability, quality perceived by patients was lower than that perceived by physical therapists, and particularly in responsiveness(t=2.82, p=.00) and empathy(t=2.02, p=.04), the difference between patients and physical therapists was statistically significant. In order to reduce the difference in the perception of service quality between patients and physical therapists, it is considered necessary to enhance physical therapists' perception of service quality and to prepare measures for improving service equality so that services would be provided through respectful communication with maintaining the dignity of patients, rather than focusing on disease.

Background and Objectives: Non-linear frequency compression (NLFC) technology compresses and shifts higher frequencies into a lower frequency area that has better residual hearing. Because consonants are uttered in the high-frequency area, NLFC could provide better speech understanding. The aim of this study was to investigate the clinical effectiveness of NLFC technology on the perception of speech and music in patients with high-frequency hearing loss. Subjects and Methods: Twelve participants with high-frequency hearing loss were tested in a counter-balanced order, and had two weeks of daily experience with NLFC set on/off prior to testing. Performance was repeatedly evaluated with consonant tests in quiet and noise environments, speech perception in noise, music perception and acceptableness of sound quality rating tasks. Additionally, two questionnaires (the Abbreviated Profile of Hearing Aid Benefit and the Korean version of the International Outcome Inventory-Hearing Aids) were administered. Results: Consonant and speech perception improved with hearing aids (NLFC on/off conditions), but there was no significant difference between NLFC on and off states. Music perception performances revealed no notable difference among unaided and NLFC on and off states. The benefits and satisfaction ratings between NLFC on and off conditions were also not significantly different, based on questionnaires, however great individual variability preferences were noted. Conclusions: Speech perception as well as music perception both in quiet and noise environments was similar between NLFC on and off states, indicating that real world benefits from NLFC technology may be limited in Korean adult hearing aid users.
