For the study of the temporomandibular joint in rheumatoid arthritis 30 patients were selected who were diagnosed as rheumatoid arthritis through the clinical, radiographic examination and laboratory findings. Temporomandibular joint involvement was evaluated through the clinical, radiographic examination. The results were as follows; 1. TMJ was involved in 15 patients of 30 patients with rheumatoid arthritis. (50% involvement). 2. Duration of rheumatoid arthritis was more longer in patients with TMJ involvement than in patients without TMJ involvement. 3. Osseous changes in TMJ were in order of frequency erosion, flattening, osteophyte, sclerosis, deformity, and most common involved site was mandibular condyle. 4. Most common positional change of condyle was forward position in centric occlusion, and restricted movement of condyle in 1inch mouth opening. 5. TMJ involvement of rheumatoid arthritis was almost bilateral. 6. Main symptoms of TMJ were pain, stiffness, tenderness, limitation of mouth opening, crepitation 7. There was not the case of ankylosis. 8. There was statistically insignificant correlation between mandibular deviation and TMJ involvement, but some cases showed severe deviation on mouth opening.

Purpose: The purpose of this study was to examine the effect of patient perception of the switching cost and negative word of mouth on revisit intention of patients in out-patient departments (OPDs) of general hospitals. Method: The participants were 306 patients in general hospital, selected through convenience sampling. Data were collected using a structured questionnaire and analyzed using descriptive statistics, Spearman correlation coefficient, and logistic regression with SPSS Win. Results: Relational switching cost was positively correlated with revisit intention (r=.58, p=<.001), but not financial switching cost or procedural switching cost. Negative word of mouth was negatively correlated with revisit intention (r=-.22, p=<.001). The significant predictors influencing revisit intention in patients was relational switching cost. Conclusion: The findings of this study suggest that hospital and nursing managers should seek to bolster perceptions of switching costs and negative word of mouth, which subsequently increases revisit intentions in small hospitals located in the country as well as urban large hospitals.

Purpose: The purpose of this study was to describe the health care experiences among patients with Parkinson's disease. Methods: Of the qualitative research methods, Colaizzi's phenomenological method was used in this study. A total of nine patients, who were diagnosed with Parkinson's disease and receiving outpatient treatment, were selected as the subjects of this study. Subsequently, data were collected through individual in-depth interview. Results: The four categories obtained as a result were 'strenuous efforts to control my own body,' 'subject of health that no one can replace,' 'focus on the current while expecting a breakthrough in health management,' and 'human dignity that cannot be lost to the end.' Conclusion: The study results are expected to help health care providers deeply understand the experiences in health care among patients with Parkinson's disease and to provide source data for nursing intervention development that can be helpful in managing the health status of patients with Parkinson's disease.

In view of the hypothesis that the effects of Parkinson disease on voice production can be detected before pharmacological intervention, the voice differences of patients with Idiopathic Parkinson's disease and a healthy aging group were diagnostically analyzed with the long term object of establishing, for clinical purposes, early disease-progression biomarkers. Fifteen patients with Idopathic Parkinson's disease (prior to pharmacological intervention) and a healthy control group of 15 were selected and every voice was recorded three times using praat (ver. 5022) with a headset mic. Relevant parameters - acoustic measure of /a/ phonation, F0 related parameters, MPT related parameters, articulatory ratio, VOT - were then analyzed by MANOVA. Significant differences were found in the F0 related (low F0, high F0, F0 range) and MPT related parameters. There were also significant differences in acoustic measurements (intensity, shimmer, HNR, jitter), AMR (/$t{\Lambda}$/,/$k{\Lambda}$/) and VOT (/ta/), The findings indicated that the voice production of patients with Idiopathic Parkinson's disease have normal pitch but bad quality. In particular, with slow articulatory ratios and VOT values, the tongue tip functioning of patients was lower than for the healthy group.

Objectives: The objective of this study is to report the effectiveness of Chuna treatment and burning acupuncture therapy on shoulder impingement syndrome. Methods: Among the patients with shoulder pain, We selected 3 patients diagnosed as shoulder impingement syndrome by physical examination and magnetic resonance imaging(MRI). After Chuna treatment and burning acupuncture therapy, we evaluated the effectiveness by measuring range of movement(ROM) and checking The Shoulder Pain And Disability Index(SPADI) every three times the patients called at the clinic for three weeks. Results: The symptoms of the patients got improved relatively in short period considering shoulder impingement syndrome belongs to chronic diseases and steps chronical procedure in recovering. Conclusions: These cases showed Chuna treatment and burning acupuncture therapy could be applied on shoulder impingement syndrome and were effective for improving the symptoms. We suggest that further studies and clinical trials will be needed afterwards.

The purpose of this study is to investigate the cytogenetic characteristics of Down's syndrome in Korea. For this study, selected were 92 patients who were diagnosed as Down's syndrome by the chromosomal analyses, among 115 patients who were supected of Down's syndrome and referred to the Cytogenetic Laboratory, Institute of Reproductive Medicine and Population, Seoul National University, for 2 years from January 1984 to December 1985. Among 92 patients with Down's syndrome 83 (90.2%) had G-trisomy, 4 (4.3%) had translocation, and 2 (2.2%) had mosaicism of normal and G-trisomic cell lines. Two patients of the remaining 3 had both G-trisomic and translocation, 47, XX, t (1:21) (p32:q22), +21, 47, XX, t (9:11) (q34:q14), +21. The remaining 1 patient had 47, XY, +mar.

Purpose: This study was done to provide fundamental data for developing a depression prediction model by discovering main factors that affect depression in patients who do maintenance hemodialysis. Method: The subjects were 191 patients doing maintenance hemodialysis selected from outpatient dialysis clinics at 9 major general hospitals, The Instrument tools utilized in this study were adapted from depression, fatigue, sleep disturbance, stress, adaptation, symptoms, daily activities, and role limitation and thoroughly modified to verify reliability and validity. The collected data was analyzed with a SPSS-PC 11.0 Window Statistics Program for real numbers, percentage, average, standard deviation, and multiple regression. Results: The correlation factor for depression was (M=2.54) fatigue(M=3.12), sleep disturbance (M=2.82), stress(M=3.04), adaptation(M=2.53), daily activities(M=2.24), symptoms(M=2.37), and role limitation(M=2.24). The strongest factor that affected depression was explained by symptoms of the patients who performed hemodialysis. The analysis of the factors that affected depression revealed a $58.4\%$ prediction in symptoms, stress, role limitation, and adaptation. Conclusion: It has been confirmed that the regression equation model(Depression=7.351 + .266$^{\ast}$symptoms + .260$^{\ast}$stress -.l89$^{\ast}$adaptation + .057$^{\ast}$fatigue) of this research may serve as a prediction factor for depression in Hemodialysis Patients.

Objective : To evaluate autonomic nerve balance and sympathetic nerve activity in patients with inner ear dysfunction as examined by heart rate variability(HRV) Research Methods and Procedures : One hundred and twenty three patients(between 15 to 59 years old) who visited Dept. of Oriental medical Opthalmology & Otolaryngology, Kyunghee university and had an examination of HRV test, were selected as subjects of our study. We checked items of HRV test(such as SDNN, RMSSD, LF, HF, TP, norm-LF, norm-HF, LF/HF ratio), and analyzed time and frequency domain differences between three groups classified as tinnitus, hearing loss and vertigo. And we compared HRV items(such as SDNN,RMSSD, TP and LF/HF ratio) with standard levels. Results and Conclusion : Our results showed no significant differences between three groups in HRV items except for mean heart rate. Patients with inner ear dysfunction showed significant lower TP than 2000$(ms^{2})$(p <0.001) and significant higher LF/HF ratio than 1.5(p=0.003). So we suggest that patients with inner ear dysfunctions such as tinnitus, vertigo and hearing loss, have sympathetic hypertonus and inactivity of autonomic nerve regulation.

The purpose of this study is to investigate the determinants of caregiver's conflict experience in elderly care institutions. This study focused on the three key independent variable groups(e.g., socio-demographic, job-related, and individual personality). The sample used in this study are 311 caregivers who are randomly selected from 21 elderly care institutions in Korea. Data were collected with a structured questionnaire by mail from Oct. 15 to Nov. 30 in 2007. The collected data were analyzed using logistic regression. The major findings of the study are as follows: 1) Nearly 40% percent of the respondents reported that they had experienced conflicts with elderly patients. The conflict with other caregivers ranked as second(20.6%), followed by patients' families(18.6%) and hospital employees(15.1%). 2) The personality, especially uniqueness caused conflict with patients or other caregivers. The professional identity reduced conflict with patients. The negative work experiences caused conflict with patients or family. The service attitude reduced conflict with family. The service-centered culture reduced conflict with hospital employees. Those who lived with the elderly showed lower level of conflict with family or hospital employees.

Background: Over the years, disc surgery has progressively evolved in the direction of decreasing trauma and its invasiveness. Conventional open surgery has many complications, such as scarring, instability, bleeding and a relative high mortality rate. Minimally invasive spinal surgery is now an alternative to a traditional discectomy. Herein, we present an operative technique, and the early results, for a percutaneous endoscopic lumbar discectomy in herniated lumbar disc disease. Methods: 43 patients, including 27 men and 16 women, with ages ranging from 18 to 66 years, were enrolled in this study. All the patients showed a protruded or extruded soft disc herniation at the lumbar level on magnetic resonance imaging and computed tomography. A percutaneous endoscopic lumbar discectomy was applied to the patients, and clinical responses evaluated using MacNab's criteria. Results: 40 patients were regarded as showing successful responses (93.1%), and there were no severe complications, such as a hematoma, nerve injury, postoperative dysesthesia or death. One patient underwent fusion surgery for remnant back pain six month later. Conclusions: We conclude that, in properly selected patients, a percutaneous endoscopic lumbar discectomy is a safe, noninvasive and effective treatment modality for herniated lumbar intervertebral disc disease.
