PURPOSE: This study was to ascertain whether there are differences in health care utilization and expenditure for Type I Medical Aid Beneficiaries before and after applying Copayment. METHODS: This study was one-group pretest posttest design study using secondary data analysis. Data for pretest group were collected from claims data of the Korea National Health Insurance Corporation and data for posttest group were collected through door to-door interviews using a structured questionnaire. A total of 1,364 subjects were sampled systematically from medical aid beneficiaries who had applied for copayment during the period from December 12, 2007 to September 25, 2008. RESULTS: There was no negative effect of copayment on accessibility to medical services, medication adherence (p=.94), and quality of life (p=.25). Some of the subjects' health behaviors even increased preferably after applying for copayment including flu prevention (p<.001), health care examination (p=.035), and cancer screening (p=.002). However, significant suppressive effects of copayment were found on outpatient hospital visiting days (p<.001) and outpatient medical expenditure (p<.001). CONCLUSION: Copayment does not seem to be a great influencing factor on beneficiaries'accessibility to medical services and their health behavior even though it has suppressive effects on outpatients' use of health care.

PURPOSE: The purpose of the study was to compare recipients' health behavior, attitude to using medicaid, medication compliance, and the changes in hospital cost and visit-day of in-patient and out-patient care between tele-care regions (TCR) and general care regions (GCR) in Korean medicaid. METHOD: The design of the study was ex-post facto comparing recipients in TCR and GCR. The sample included 625 persons in TCR and 410 persons in GCR. To collect materials, the case manager interviewed recipients of medicaid and filled out questionnaires which were analyzed through SAS/PC 9.1. RESULTS: In studying health behavior and medication, compliance was not significant. However, the attitude to using medicaid was significantly more positive in TCR than in GCR. In out-patients, the change of hospital visit-day was not significant between TCR and GCR, but TCR showed a reduction in hospital cost compared to GCR. For in-patient recipients, GCR showed a greater reduction in changes in hospital cost and visit-day compared to TCR. CONCLUSIONS: The results of the study show that attitudes to using medicaid via telephone are positive and results are more effective than hospital visit consultation, and the cost of out-patient care could be reduced.

PURPOSE: This study aims to develop a tool to predict occupational health patients' nursing needs or nursing time. METHOD: A tool was composed based on the materials and opinion of experts, and to verify the reliability and validity of the tool, nursing time of total 311 inpatients in 2 occupational health hospitals were surveyed. RESULTS: The developed tool was total 151 items and composed of physical function, cognitive function, communication, emotional and disturbance behavior, nursing skill, and rehabilitation need. The reliability of the tool was high, showing Cronbach's alpha coefficient of 0.95. But several items should be deleted for low corrected item-total correlation. According to the multiple regression analysis, physical function and rehabilitation need were shown to be the most powerful predictive variables for nursing time. CONCLUSION: The developed tool was appeared to have high reliability and validity. But further refinement of the tool is needed.

PURPOSE: The purpose of this study was to investigate the actual condition of the disabled due to Occupational accidents based on the functional evaluation tool. METHOD: The data were collected from 2 Workers Accident Medical Corporation, 311 subjects between February and August, 2007. The tool comprised of six components including physical function, cognitive function, communication, emotional and disturbing behavior, nursing skills and rehabilitation needs. RESULTS: Among the disabled, the average point of physical function of 5 was found in 61.92% and to express and understand were evaluated as normal in 36.69% and 33.44%, respectively. Also, hearing and vision were evaluated as normal in 53.50% and 37.98%, respectively. 19.01% of the disabled had emotional problems and 13.78% had disturbing behavior. Most disabled were in need of nursing skills with 97.73% ROM and activities. The 78.18% and 76.90% of disabled were in need of rehabilitation because of right and left leg in full movement disorders, respectively. CONCLUSION: The evaluation score for the disabled caused by Occupational accidents was diverse showing 10 to 19 points and 140 to 150 points. The result means the care cost should be determined depending on the care needs of the disabled because there is such a diverse range of care needs for them.

Sarcoidosis is a rare but potentially fatal multisystem granulomatous disease of unknown etiology. While a number of clinical manifestations may develop, cardiac involvement (prior to or coincident with sarcoidosis of other organs) is an important prognostic factor. Recently, we encountered a patient with cardiac sarcoidosis who presented with complete atrioventricular (AV) block and sustained ventricular tachycardia. An implantable cardioverter-defibrillator was inserted as a precautionary measure for ventricular tachycardia and symptomatic complete AV block. 18F-fluoro-2-deoxyglucose positron emission tomography confirmed a dramatic response to high-dose steroid at four weeks, as demonstrated by a marked decrease in cardiac sarcoid activity from baseline status.

The kidney size is of special interest during the diagnostic work up of acute lymphocytic leukemia. But is still uncertain whether a finding of kidney enlargement at presentation has long-term prognostic value. We therefore reviewed the kidney size in children with acute lymphocytic leukemia by abdominal ultrasonograms at the time of diagnosis (n=54) and exmined if there was any statistical significance between the kidney size and prognostic parameters and later outcome. The following results were obtained 1) Among the patients whose kidney size was enlarged over 4SD from the normal, hepatomegaly in 3 cases (20%), splenomegaly in 3 cases (20%), mediastinal widening in 2 cases (13%) were noted. The interrelation between kidney size and infiltration of extramedullary system had no statistical significance. 2) Among the patients whose kidney size was enlarged over 4SD from the normal, patients under age 2 and over age 10 in 5 cases (33%), male in 8 cases (53%), involvement of central nervous system in 1 cases (7%), WBC count over 100x10E9/L in 3 cases (20%), Hb over 10 g/dl in 3 cases (20%) and platelet count below 100x10E9/L in 3 cases (20%) were noted. There was no statistical significance between kidney size and infiltration of extramedullary system. 3) Two Year survival rate based upon kidney size was; 95% in the group below 2SD, 79% between 2SD and 4SD, 59% over 4SD. And 2 Year event free survival rate was 71%, 56% and 58 respectively. In conclusion, the kidney size in childhood acute lymphocytic leukemia at the time of diagnosis influences the late outcome, but it is not a meaningful prognostic parameters.

The present study was performed to trace the decisive evidence for mixed infection of 2 Myxobolus species, M. episquamalis and Myxobolus sp., in the gray mullet, Mugil cephalus, from Korean waters. Mullets with whitish cyst-like plasmodia on their scales were collected near a sewage plant in Yeosu, southern part of Korea, in 2009. The cysts were mainly located on scales and also found in the intestine. The spores from scales were oval in a frontal view, tapering anteriorly to a blunt apex, and measured 7.2 microm (5.8-8.0) in length and 5.3 microm (4.7-6.1) in width. Two polar capsules were pyriform and extended over the anterior half of the spore, measuring 3.5 microm (2.3-4.8) in length and 2.0 microm (1.5-2.2) in width. In contrast, the spores from the intestine were ellipsoidal, 10.4 microm (9.0-11.9) in length and 8.4 microm (7.3-10.1) in width. The polar capsules were pyriform but did not extend over the anterior half of the spore, 3.7 microm (2.5-4.5) in length and 2.2 microm (1.8-2.9) in width. The nucleotide sequences of the 18S rDNA gene of the 2 myxosporean spores from scales and intestine showed 88.1% identity to each other and 100% identity with M. episquamalis and 94.5% identity with M. spinacurvatura from mullet, respectively. By the above findings, it is first confirmed that mullets from the Korean water are infected with 2 myxosporean species, M. episquamalis and Myxobolus sp.

OBJECTIVE: The purpose of this study was to determine whether cyclooxygenase [COX]-1 and COX-2 are expressed in the pregnant human uterine cervix and if they are expressed differentially between preterm and term pregnancies. METHODS: Fourteen patients delivered between 29 and 41 weeks of gestation were matched for obstetrical history and maternal age were divided into a preterm group who delivered between 29 and 36 weeks [n=7], and a term group who delivered between 37 and 41 weeks of gestation [n=7]. Immediately after vaginal delivery cervical biopsy samples were obtained and immunohistochemicaly stained for COX-1 and COX-2 and the degree of staining was evaluated by H-scoring system. RESULTS: Expression of COX-1 and COX-2 was found in all epithelial and stromal cells of uterine cervical tissues of pregnancy. The expression of COX-1 and COX-2 was significantly stronger in the term group compared to the preterm group in epithelial cells [HSCORE : 2.14+/-0.69 vs. 1.14+/-0.38 ; 3.71+/-0.76 vs. 1.86+/-0.90, p<0.05], but there was no significant differences in stromal cells [HSCORE : 3.43+/-0.53 vs. 2.86+/-0.38 ; 2.43+/-0.53 vs. 2.57+/-0.98, p>0.05]. CONCLUSION: In the pregnant human uterine cervix, COX-1 and COX-2 are found to be expressed, and both are strongly expressed in the cervical epithelial cells of term pregnancies compared to preterm pregnancies. It is suggested that the uterine cervix, under the control of prostaglandins, is actively involved in the process of labor, and that the role of COX-2 in epithelium is particularly significant in term pregnancies compared to preterm pregnancies.
