OBJECTIVE: To evaluate the relative benefits and the costs associated with the introduction of the new pharmaceutical provision called 'Mandatory Prescription Syste m' which separates the role of physicians from that of pharmacists with respect to the prescription and dispensation of from the perspective of consumers (i.e., patients). METHODS: The costs of the system were measured by considering both direct and indirect costs. Direct costs included additional payments for ambulatory care and dispensing fees that occurred under the new system. Indirect costs consisted of transportation expenses and costs related to time spent for physician consultation, waiting for the prescriptions to be filled, and extra traveling. Benefits identified in this study were the reduction of drug misuse and overuse, and the overall decrease in drug consumption among the Korean population. Sensitivity analysis was performed for the inclusion of benefits for outpatients of hospitals, price elasticity, and increased fees for established patients. RESULTS: The net benefit was estimated to be about minus 1,862 billion won and the benefit-cost ratio was 0.478. This indicates that the costs of 'Mandatory Prescription' outweigh its benefits, relative to the previous system. The sensitivity analysis results for all the variables considered in this study consistently showed the benefit-cost ratio to be less than 1. CONCLUSION: The results of this study suggest that implementing Mandatory Prescription System in Korea might be inefficient from the consumer's perspective. The results of this study do not coincide with the results of previous studies, presumably because of the differences in study design and in which items of costs and benefits were considered.

Sex cord stromal tumors (GCT) of the ovary compose just 5% of ovarian tumors. Most of them are granulosa cell tumors (GCT). There are two types of tumors, juvenile (JGCT) and adult type (AGCT), which have different clinical and histopathological features. JGCT represents only 5% of GCT. GCT is characterized by secretion of estrogen. Patients may present with vaginal bleeding in adult type, and sexual pseudoprecocity in juvenile type, as results of prolonged exposure to tumor-derived estrogen. Surgery is a principle of treatment and required for definite tissue diagnosis, staging, and tumor debulking. Survival of patients with GCT is generally excellent because most patients present with early stage disease. Because of the propensity of GCT to recur years after initial diagnosis, prolonged surveillance such as physical examination and serum tumor markers such as estradiol and inhibin is reasonable. We present 5 cases GCT, 4 AGCT and 1 JGCT, with brief review of literature.

OBJECTIVE: The change of claudin expressions, integral transmembrane proteins for tight junction, might be related to progression of cervical premalignancy or malignancy. The aim of this study was to verify the tendency of expressions of claudin-1 and -7 according to the progression of cervical pathology of uterus. METHODS: There were 162 tissues obtained at AA institute. 25 tissues were normal, 26 were cervical intraepithelial neoplasia (CIN) 1, 30 were CIN2, 44 were CIN3, 25 were microinvasive cervical carcinomas, and 12 were invasive squamous cervical carcinomas (ISCC). H and E and immunohistochemical staining were done. RESULTS: Among normal tissues, 52% showed no expression, 48% weak expressions at claudin-1, and 28% no expression, 56% weak expressions at claudin-7. Among CIN3, 20% showed weak expressions, 41% showed moderate expressions at claudin-1, and 14% weak expressions, 52% moderate expressions at claudin-7. Among ISCC, 42% showed moderate expressions, 50% strong expressions at claudin-1, and 33% moderate expressions, and 33% strong expressions at claudin-7. These data shows the increasing tendency of claudin-1 and claudin-7 expressions according to the severity of lesions (p<0.01). CONCLUSION: The expressions of claudin-1 and claudin-7 were increased more according to the progression of cervical lesions.

OBJECTIVES: Understanding the predictor of immunization status in childhood is critical issue to improve National Immunization Program (NIP). The aims of this study were to verify the status of up-to-date or complete immunization coverage and to investigate its related factors. METHODS: As of 2005, according to local residence registry data, there were 2,188 children who aged 12 to 35 months in Nonsan city, Korea. We conducted household survey for aged 12 to 35 months children, using questionnaires to obtain data on the status of immunization such as BCG, DTaP (diphtheria, tetanus, and pertussis), Polio, and MMR (mump, measles, rubella). Finally 1,472 participated in the survey. The operating definitions used in this study were following; "Complete immunization rate" refers to the rate of children who received all immunization within recommended age intervals fully "on-time"; "The 4:3:1 series" means status of receiving the fourth diphtheria-tetanus-pertussis (4 DTP), the third Polio (3 Polio), and the first measles-mumps-rubella (1 MMR) doses. Multivariate logistic regression analyses were used to determine factors affecting complete vaccination coverage of children. RESULTS: Immunization rates of vaccine based on the vaccination card were from 92.7% to 96.4% except 4th DTaP (79.3%). Complete immunization rate of Korea NIP was 74.0% and that of the 4:3:1 series was 77.1%. A parent as primary caregiver (OR 0.59, 95% CI 0.39-0.87 at 19-35 months of children's age) and first-born children (OR 1.79, 95% CI 1.05-3.03 at 24-35 months of children's age) were significantly related to complete immunization coverage of Korea NIP. And a parent as primary care giver (OR 0.58, 95% CI 0.38-0.88 at 19-35 months of children's age) and first-born children (OR 1.94, 95% CI 1.21-3.14 at 19-35 months, OR 2.23, 95% CI 1.27-3.91 at 24-35 months of children's age) were significantly related to complete immunization rate of 4:3:1 series. CONCLUSIONS: Government should take actions to increase complete immunization rate. In particular, intervention on the secondary caregiver and non-first-born children should be needed.

OBJECTIVES: To evaluate the degree of adolescent internet addiction, and investigate its relationship to the general characteristics, internet environments, and contents, especially the stress measured by the psychosocial wellbeing index-short form (PWI-SF). METHODS: The data was obtained from self-administered questionnaires from 886 11th grade urban area students. The questionnaires consisted of general characteristics, internet user's environments, frequencies by internet contents, internet addiction test and PWI-SF. RESULTS: The possible rate of internet use at home was 95.1%, and the area of most internet use was the home. The frequencies of internet game and porno site use were higher in males, with web searching and community uses higher in females. The total mean of internet addiction score was 56.8, and was higher for male than for female students. From multiple regression, as analyzed by the internet addiction score as a dependent variable, on-line friends, internet use times, years of internet use, frequencies of internet game & porno site use, and PWI-SF scores were significant in male. Internet use times, the frequencies of internet game, chatting, community use, and PWI-SF score were significant in female. Four PWI-SF subscales (social role & self reliability, depression, general health & vitality, and sleep disturbance & anxiety) and internet addiction were significantly correlated in both male and female students, with depression having the most correlation. CONCLUSION: The results of this study suggest that intervention should be provided to prevent internet addiction, especially for coping with stress in Korean teenage students.

BACKGROUNDS: To investigate the physical functioning state of the rural aged people and its related factors. METHODS: 458 older people aged 65 years or older living in a rural area were interviewed fromAug. 6 to Aug. 9, 2003. Socioeconomic characteristics, structural and functional social supports, chronic disease, stress, and obesity(using body mass index) were included to explore their influencing physical functioning. Physical functioning was measured by Physical Functioning(PF) scale constructed by 2-factor(mobility and self-care). Cronbach's alpha of social support and PF scales were 0.91, 0.89 respectively. After univariate analysis, multiple regression analysis was conducted to identify major contributing factors to physical functioning. RESULTS: 1) Person of younger age, higher education level, having job, higher economic status were more likely to show a higher degree of physical functioning in both male and female. 2) In those who having spouse, the physical functioning scores were significantly higher. And the aged people with high social support got higher physical functioning score. 3) In male with diabetes, physical functioning score were significantly lower. In female with arthritis, physical functioning score were significantly lower. 4) For the aged people which having higher stress, the physical function wasn't good. 5) In multiple regression analysis, for both male and female, physical functioning of those who have no job, lower social support, higher stress was bad. In male with chronic disease and female with arthritis, the physical functional score was lower. CONCLUSION: The physical functioning of some rural aged people were affected by various factors such as social, psychological, economic and physical factors. So diverse policy and programwill be necessary for improve physical functioning of rural older people.
