In the present study, we investigated ability of recognition of auditory perception with regards to the quality of voice in postlingual CI adults and proposed a training program to improve within subject reliability. A prospective case-control study was conducted in adults with 7 postlingual deaf who received a CI surgery and 10 normal hearing controls. The pre and post test and training program included parameters of consensus auditory-perceptual evaluation of voice(CAPE-V) with pathological voice sample by using Alvin. In results of pre-post test for monitoring improvements of internal reliability for listeners via the training program, there was statistically significant difference in both test and group. There was statistically significant difference in internal reliability between pre-post test in the normal hearing group, the result was no significant in the CI group. The present study found that CI adults showed less ability in awareness of voice quality compared to normal hearing group. Also the training program improved pitch and loudness in CI adults.

Purpose: The purpose of this study was to test the effects of the Tai Chi exercise on metabolic syndrome and health-related quality of life in middle-aged women. Methods: A quasi-experimental design was used. Subjects were sixty middle-aged women with metabolic syndrome. All of the subjects were met the criteria of the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III). The subjects were divided into the experiment group (n=33) trained the Tai Chi for 12 weeks and the control group (n=27). Metabolic syndrome risk factors including blood pressure, waist circumference, glucose, triglyceride (TG), and high density lipoprotein cholesterol (HDL-C) were measured before and after the 12-week period. Euro Quality of Life Questionnaire 5-Dimensional Classification (EQ-5D) was used to evaluate the health-related quality of life. Results: The experiment group showed significant decreases in diastolic blood pressure, waist circumference, glucose, and TG; and increase in HDL-C compared to the control group. For the health-related quality of life evaluation, the experiment group showed significant improvement more than the control group. Conclusion: The Tai Chi exercise may be effective intervention in preventing cardiovascular disease caused by metabolic syndrome in middle-aged women.

Purpose: The purpose of this study was to examine the effects of integrated psychoeducational program for distress management of newly diagnosed patients with breast cancer. Methods: A quasi-experimental trial was conducted. The participants consisted of 47 female patients with breast cancer assigned to an intervention group (n=25) and control group (n=22). The intervention group participated in integrated psychoeducational program, consisting of individual face-to-face education and telephone-delivered health-coaching sessions. Data were collected at three time points: pre-intervention (T1), post-intervention (T2), and 6-month follow-up (T3). Study instruments were Distress thermometer, Supportive Care Needs Survey Short Form 34 and Functional Assessment of Cancer Therapy-Breast. Results: Compared with the control group, breast cancer patients in the intervention group reported lower distress and supportive care needs than the control group. The intervention group reported higher quality of life (QOL) overall and higher emotional well-being than the control group. Conclusion: These findings indicate that the integrated psychoeducational program is an effective intervention for reducing distress and supportive care needs and increasing QOL of newly diagnosed patients with breast cancer. Oncology nurses need to provide psychoeducational intervention to support patients with breast cancer in managing their distress and helping them adjust to their life.

Quality Control programs for industrial hygiene laboratory have successfully been operated since the 1st round was initiated in April 1992. Three rounds have been completed. Overall analytical performance of participants was improved through a subsquent round. The first round had a large variation among analytical results of all participants, 26.34%~504.22% of coefficient of variation. But the variation of analytical performance in the 2nd and 3rd rounds decreased to 40.42%~52.55% and 10.74%~20.98%, respectively. The difference of analytical performance among participants was decreased by operation of subsquent round. By distribution of Running Performance Index (RPI), over 50% of participants belongs to Category 3 in the first round. The average percentage of participants assigned to Category 3 in the 2nd and 3rd round was decreased to 37.2%. A definite analytical performance improvement of participants seems to be obtained. "A" and "B" group have more participants assigned to Category 3 than those of "C" group through the distribution of RPI by group divided to similar participant. By the distribution of RPI all participants, the percent of participant being over 200 RPI in the 1st round was 43%~52%, but decreased to 9%~29% and 9%~27%, in the 2nd and 3rd round, respectively. These results mentioned above indicate that the analytical performance of all participants have been improved by subsquent Quality Control Program although newcomers joined and a few participants droped out. But, there are some participants with poor analytical performance. Industrial Health Research Institute (IHRI) will offer service such as education, communication and visitation to them, and improve quality of their analytical performance in the future.

Short runs where it is neither possible nor practical to obtain sufficient subgroups to estimate accurately the control limit are common in modem business environments. In this study, the standardized control chart, Hillier's exact method, Q chart, EWMA(Exponentially Weighted Moving Average) chart for Q statistics and EWMA chart for mean and absolute deviation among many SPC(Statistical Process Control) techniques for short runs have been reviewed and advantages and disadvantages of these techniques are discussed. The simulation experiments to compare performances of these variable charts for process mean and variations are conducted for combination of subgroup size, scale and timing of shifts of process mean an/or standard deviation. Based upon simulation results, some guidelines for practitioners to choose short run SPC techniques are recommended.

The quality control is needed to ensure the accuracy of medical information and achieved by evaluating the performance of and maintaining the system and practicing various measurements and evaluations. The Korean Institute for Accreditation of Medical Image, therefore, have held educational program for quality control of special medical equipments. The major of programs participants, however, are radiology specialists with only small number of radiological technologists from some hospitals, furthermore, the follow-up education and the share of information between participants and non-participants are insufficient in general, thus, the knowledge level of radiological technologists, regardless of their participation, is relatively low. This study carried out the questionnaire research for the 500 radiological technologists registered in Korean Society of MRI Technology, on the basis of 2008, and performed analysis for five months from May to Oct., 2008. The questionnaires were delivered by post to each radiological technologists and the response rate was 36%(n=180). The results of this revealed that the 86.7% of respondents felt the necessity of inspection on quality management, while only the 27.8% completed the educational program for manager of special medical equipment. and only the half(53.9%) had the knowledge about inspection on quality management. The completion of educational program had no correlations with sex, age, size of occupying hospital, the number of radiological technologists in occupying site and MRI laboratory, career year of general radiologist and in MRI laboratory, and the presence of biomedical engineering department in occupying hospital. The 78.0% of participants at the educational program for quality management held by the Korean Institute for Accreditation of Medical Image had the knowledge about inspection on quality management(p<.05) whereas the 43.9% of the hospitals held such program and the 54.4% of radiological technologists from those hospitals had related knowledge, which indicated that such programs held by hospitals had not effects on the knowledge level of radiological technologists. This indicates also that the contents, methods, and other conditional factors of educational programs are important for the outcome of them.
