This study aims to help utilize the dental treatment institutions for the disabled and provide high quality of medical services in the future by identifying the satisfaction factors for the patients of the dental clinics for the disabled. As a study method, surveys were completed 200 patients who visited the dental hospital for the disabled. Among these, the surveys from 187 patients were statistically analyzed. The main findings of this study are as follow. Since the study showed that there were differences in the satisfaction factors between the disabled and non-disabled people, subsequent studies needs to be done to develop measuring tools to accurately accommodate the satisfaction factors of the disabled. In addition, as the low spatial accessibility in terms of distance and location was found in this study, more dental treatment institutions for the disabled are required. In the meantime, the survey results found that the most satisfactory aspect was the lower treatment cost compared to other clinics, and that the most important factor when choosing a clinic was also treatment. In addition, given the fact that the group that took a prosthetic treatment, which was non-insured treatment, showed higher satisfaction compared to the group that did not, it suggests that the economic burden plays an important role for the dental treatment of the disabled.

PURPOSE. The purpose of this study was to compare the coronal bone level and patient satisfaction in 1-implant and 2-implant assisted mandibular overdentures. MATERIALS AND METHODS. Twenty patients who had maladaptive mandibular dentures were treated in this study. Patients were randomly divided into two groups. The first group received 1 implant (Simple line II, Implantium, South Korea) in their mandibular midline and the second group received 2 implants in their B and D regions (according to Misch's category). If the primary stability of each implant was at least 60 ISQ, ball attachment was placed and denture relined with soft liner. After 6 weeks, retentive cap incorporated with hard acrylic resin. In the 6 and 12 months recalls, periapical digital radiograph were made and visual analogue scale questionnaires were used to record patient satisfaction. The Friedman test was done for comparing the presurgical and postsurgical parameters in each group and the U-Mann Whitney test (P<.05) was done for comparison of post-treatment results between the two groups. RESULTS. All implants achieved sufficient primary stability to be immediately loaded. Patient satisfaction was high, and there were no significant differences between two groups (P>.05). In addition, mean marginal bone loss was $0.6{\pm}0.67$ mm in the first group and $0.6{\pm}0.51$ mm in the second group, after 12 month. Mean marginal bone loss showed no significant differences between two groups. CONCLUSION. This preliminary one-year result indicated that mandibular overdentures anchored to a single implant can be a safe and cost-effective method as a starting step for implant-overdenture treatment.

Magnetic Resonance Imaging(MRI) is one of the most expensive and sophisticated diagnostic tool and has been hailed as the most exciting event in medical imaging "since the introduction of X-rays", but a major disadvantage, high cost, is coming into focus especially in our country. To determine the status of distribution of MR imagers in Korea and to serve as a basic material for an efficient utilization of this Imaging machine, a retrospective survey of nationwide and regional(3 hospitals in Pusan) installations was performed. The results were as follows : 1. As of April 30, 1991, a total of 33 MRI units(24 for superconducting, 6 for permanent and 3 for resistive units) were set up and operated. 91% of the units were distributed in big cities with no one installation in 7 provinces among 12 provinces in our country. 85% of the units were imported. 2. Although 42.4% of the units were operated in Seoul, Taejeon had the best condition for the distribution of this imaging machine per population, hospital, and bed in Korea. 3. In Pusan : a) 5 units were operated with all superconducting magnet and medium magnetic field in type of machine. b) 80.1 % of the examinations were central nervous system(CNS). c) MRI examination occupied 1.4% of all radiographic examinations and the patients referred from other hospitals were composed of 23.4%% of all patients. 4. The average days under operating of MRI unit a week in Puasn were higher(5.5) than that of Seoul(4.5), but the average number of examinations and hours a week and a day, respectively(33, 8.4), was less than that of Seoul(57, 12.9). 5. The patients with positive MRI findings in a hospital(B) in Pusan was 74.5% on an average.

Hospitals in Korea are having trouble with economic matters because of the low cost of medical insurance and the consumer's demand for high-quality care. The management of patient clothing is very difficult Especially for the management of size is very difficult because the mix of patients in the wards is very different from the stocked clothing sizes. Because of economic matters the ward dose not prepare enough clothing for every size. The nurses in the wards have trouble managing the clothing. Therefore the nurses want free-size patient clothing for all patients. The problem of managing the patient's clothing were surveyed by nureses in the wards. It was known that the free-size patient clothing was needed. The clothing designed from 150cm, to 180cm by 5cm were made. The different sizes of clothing were pretested. The experimental clothing were selected. The experimental patient clothing are designed for between from 165cm and 170cm in height which refers to Korean average. The fitness and sensory test were made by medical personnel outpatient who will be future client for hospital and by specialist in clothing. Finally The free-size patient clothing was made. It was said that there is no difference between the C-type (170cm) and the D-typer(165cm) clothing by specialists in clothing. The outpatient future client for hospital liked the C-type was selected. The questionnaires of the C-type patient clothing was tested by outpatient patients and by medical personnel. Eighty-four point-eightprecent(84.8%) of evaluators liked free-size clothing 75.8% liked unisex use.

The incidence and mortality of cervical cancer remains high in India even after sixty years of introduction of the Pap smear (cervical cytology) which is an effective means of identifying preinvasive lesions of carcinoma cervix. The morbidity and mortality due to cervical cancer has come down drastically in countries with well established screening programmes at national level. This study aims at screening women for cervical cancer opportunistically during their visit to hospital and to study various types of neoplastic and non-neoplastic lesions of the cervix by cervical smear study (Pap smear study). In the present study, a total of 350 cervical smears were studied. The age of patients ranged from 19 years to 80 years with mean age being 37.5 years. Out of 350 cases, the diagnosis of neoplasia was given in 43 cases and 258 cases were diagnosed as inflammatory smears. Forty-cases were normal and 9 cases were inadequate to evaluate. Forty-three patients who were found to have neoplastic lesions on cytology were referred for further investigations like colposcopy and biopsy to confirm the diagnosis and avail proper treatment. Limitation of the present study was small sample size as all female patients aged between 20 and 60 years visiting hospital were not included in the screening, other screening tests like VIA (visual inspection with acetic acid test) and HPV DNA (human papilloma virus) tests were not done. Until the time centrally organised screening programmes for cervical cancer are established in India, arrangements should be made for hospital based opportunistic screening for all women attending hospital. The cost effectiveness of different screening tests for cervical cancer should be evaluated.

Adverse drug events (ADEs) are the most common type of adverse events in medical practice. Hospital admissions related to ADEs cost high and should be monitored to prevent them. While concerns about the ADEs are increasing, the frequency and characteristics of admissions related to ADEs have not been reported in Korea. The objective of the study was to assess the rate of hospital admission related to ADEs and their characteristics through ADE signal-based retrospective reviews of medical records. As results, a total of 1,420 patients had ADE signals suggesting potential ADEs from 3,494 patients who discharged from an academic medical center over one month period. Six pharmacists independently assessed the presence of ADEs after the review of patients' medical records. Among the 3,494 discharges, 62 admissions (1.8%) were found to be realted to ADEs. Of admissions with ADEs, 83.9% were moderate (category F by the NCC MERP classification), 37.2% were preventable, and 85.5% were type A reaction. The most frequent suspected drugs causing ADEs were antineoplastics (48.9%), and the most frequent ADE signal detecting hospital admissions related to ADEs was white blood cell count (24.2%). Hospital admissions related to ADEs were found through screening the ADE signals. The ADE signal-based retrospective review could be a practical approach for identifying hospital admissions related to ADEs.

Computed tomography(CT) has become more widely available in recent years and is recognized as an important diagnostic tool for complex disease and condition of the orofacial structure in adults. In pediatric patients, especially in the mixed dentition period, the number of superimposing dental structures in the jaw bone is much greater than in the permanant dentition period. Therefore, in spite of radiation risk, computed tomography should sometimes be used in pediatric patients in order to obtain a precise and valid diagnosis. This case study presents clinical application of computed tomography on patients visiting department of pediatric dentistry in Seoul National University Dental Hospital. The results obtained through these cases were summarized as follow : 1. Localization of impacted teeth using CT allows for efficient treatment planning leading to reduced postoperative complications. 2. In orthodontic traction of impacted permanent teeth, utilization of CT made exact localization of window site and determination of prognosis possible. 3. Use of CT made possible definite diagnosis of lesions in the jaw that were only suspected on plain film radiographs. 4. Careful selection is necessary when applying CT on children due to increased radiation dose and high cost.

Purpose: Statistical analysis of facial bone fractures has been performed in various papers. However, reports on risk factors for facial bone fractures are rare. In order to prevent facial bone fractures, it is important to determine the risk factors for their occurrence. This study seeks to perform a statistical analysis on and identify the risk factors associated with facial bone fractures. Methods: A retrospective study was performed to assess facial bone fractures in patients presenting from October 2009 to January 2011 through a chart review. The data collected included age, gender, etiology, and alcohol consumption. Data was analyzed using multinomial logistic regression analysis. The significance level was set at p<0.05 and SAS ver. 9.2 was used. Results: A total of 489 patients were analyzed. The patients' age ranged from 2 to 85 years (mean age, $31.8{\pm}15.4$ years). The ratio of men to women was 5.0:1. The predominant group was age below 19 years old (30.9%). The main causes of facial bone fractures were assaults (37.8%), falls (27.2%), and sport accidents (19.5%). On multinomial logistic regression analysis, age, especially in the teen group was associated with assaults (p<0.05) resulting in facial bone fractures. Alcohol consumption was significantly associated with assaults and falls (p<0.05) leading to facial bone fractures. Conclusion: Facial bone fracture is a challenging problem, because of its high incidence and financial cost. The findings of this study indicate that more effective policies aimed at reducing alcohol intake and teenage violence are needed.

Objective : This study was intended to provide information pertaining to reasonable consumption of medical services based on comparative analysis of the characteristics of musculoskeletal diseases(MSDs) among outpatients of Korean medical institutes, and furthermore help lay groundwork for mapping out effective Korean medical policies. Method : Based on the data of 3,889 outpatients of Korean medical institutions which were obtained from the Ministry of Health and Welfare's 2011 Report on usage of Korean medicine, the analysis was carried out by using the SAS 9.2. Results : 68.2% of subjects were found to use Korean medicine(KM) for the treatment of MSDs. Patients with MSDs were older than those with nonmusculoskeletal diseases(NMSDs). And married state, education, employed state and incomes are effected on MSDs and NMSDs. Subjective health status, number of outpatient treatments, medical cost, medical treatment satisfaction, and habitue status are depend on MSDs or NMSDs. Acupuncture and physical therapy is Major treatments of subjects investigated to have the highest treatment effect. It was found that they had high degree of satisfaction with Korean medicinal outpatient treatments, and those with MSDs were found to have significantly greater satisfaction than those with NMSDs. Conclusion : Although aforesaid results suggest significant satisfaction with KM and high treatment effects for MSDs. Accordingly it is considered necessary to develop various services related to KM for treatment of MSDs and to plan for cost down of KM. Moreover, in-depth research into NMSDs is required for utilization growth of KM.

Although early diagnosis of urinary tract infection is important, the radiologic evaluation is still controversial because of the low sensitivity and the lack of cost-effectiveness. This study was carried out to evaluate the clinical utility of high resolution triple head $^{99m}Tc-DMSA$ SPECT imaging in urinary tract infection. We prospectively performed $^{99m}Tc-DMSA$ planar and SPECT imaging, ultrasound of kidney (US), intravenous pyelography (IVP) and voiding cystourethrography (VCU) in all 60 adult patients with UTI [26 with first episode of acute pyelonephritis (APN), 22 with recurrent APN, and 12 persistent asymptomatic pyuria] and 25 normal persons. To assess reversibility of the renal cortical defect (RCD), $^{99m}Tc-DMSA$ SPECT was repeated 1 to 8 months later in those patients with abnormal initial findings. Overall detection rate of $^{99m}Tc-DMSA$ SPECT imaging was 83% (50/60), but planar, US, IVP and VCU showed abnormal findings in 68%, 28%, 32% and 13%, respectively. 25 out of 27 patients with normal or single RCD were all normal in other radioligic studies. Only two patients showed vesicoureteral reflux (VUR) on VCU (grade I) and mild hydronephrosis on IVP. But, high proportion of those with multiple RCD showed abnormal findings on US (17/33), IVP (18/33), and VCU (7/33): 67% in any of these 3 studies. Especially, 3 out 7 patients with VUR showed multiple RCD on $^{99m}Tc-DMSA$ SPECT without any abnormality on IVP or US. 25 normal persons showed normal findings in all studies except one false positive finding on $^{99m}Tc-DMSA$ SPECT imaging. Follow-up $^{99m}Tc-DMSA$ SPECT was done in 28 patients (13 with single RCD, 15 with multiple RCD). All 13 patients with single RCD showed improvement. Those with multiple RCD presented improvement in 4, no change in 10, and aggravation in 1 on follow-up studies. With these results, we conclude: 1) $^{99m}Tc-DMSA$ SPECT imaging is superior to planar imaging, US, IVP or VCU in detection of renal lesion in urinary tract infection. $^{99m}Tc-DMSA$ SPECT is useful as a initial diagnostic tool in adult patients with urinary tract infection. 2) The multiple RCD on $^{99m}Tc-DMSA$ SPECT represent the high probability of irreversible tissue change and need of extensive urological work-up.
