The aim of this study was to evaluate the competency of the Easyperio test, a genetic test method based on real time PCR for the detection of bacteria that cause dental caries and periodontal disease. To verify the validity of this text, various dental health evaluations were administered to 33 boys between the ages of 12 to 14, as this age group commonly experiences dental caries. These evaluations included a dental caries experience survey, a first molar health evaluation, the Dentocult Streptococcus mutans (SM) strip mutans, the Dentocult Lactobacillus spp (LB) test, and the Easyperio test. The correlation coefficients between the level of the Dentocult SM strip mutans and the dental caries experience were DT (R=0.570, p=0.001), DMFT (R=0.376, p=0.031), and first molar health (R=-0.395, p=0.023). The correlation coefficients between the amount of SM in the Easyperio test and dental caries experience were DT (R=0.528, p=0.002), DMFT (R=0.369, p=0.035), and first molar health (R=-0.426, p=0.013). The correlation coefficients between the level of the dentocult SM strip mutans and the SM amounts of the Easyperio test were S.mi (R=0.564 p=0.001) and S.mu (R=0.621, p=0.002). The correlation coefficients between the level of the Dentocult LB test and the SM amount of Easyperio test was S.mi (R=0.495, p=0.003). In conclusion, Easyperio test may be an easy and effective method for the differentiation and diagnosis of dental caries through quantitative and qualitative analysis of oral bacteria.

The glomerular filtration rate (GFR) has been the subject of much research as a key indicator for diagnosing, treating, and monitoring kidney function. The gamma camera method (Gates method) is simple and allows simultaneous acquisition of GFR and renal scintigraphy for each kidney, however its accuracy is inferior. This study aimed to investigate changes in GFR depending on how region of interest (ROI) are set up, which is one of many factors influencing accuracy. GFR was calculated by setting the ROI for each phase of the image acquisition time (Gates-1: 0~1 minutes, Gates-2: 1~3 minutes, Gates-3: 3~27 minutes), and statistical significance was verified based on probability value 0.05 through ANOVA analysis. While there was no statistically significant difference among results from Gates-1, 2, 3 (p=0.481>0.05), overall results from the Gates method tended to overestimate compared to those from the multiple blood sampling-dual exponential (MBSDE) method. When comparing averages between phases, results from Gates-2 were most similar to those from the MBSDE method. Moreover, paired t-test p-values between MBSDE method and phases were as follows Gates-1: 0.021 (p<0.05), Gates-2: 0.280 (p>0.05), and Gates-3: 0.164 (p>0.05) indicating that only Gates-1 had statistically significant differences compared with MBSDE method. Thus, setting ROI around 2~3 minutes is calculated can aid in accurately determining GFR when Gates Method.

Purpose: This study was to determine the effect of Individualized education-counseling program on the performance of Health behavior and Cardiovascular risk after discharge inpatients with percutaneous coronary intervention. Methods: This study is a quasi-experimental study of the non-equivalence control group and the subjects of this study were patients who underwent percutaneous coronary intervention for coronary artery disease and had no complications due to severe arrhythmia or heart failure. The purpose of the study was explained to the subjects who met the selection conditions, and written consent was obtained, and 50 randomized experimental groups and 50 control groups were selected and assigned. Results: Compared to the control group, health behaviors were significantly higher after 1 week (F=33.63, p<.001) and 12 weeks (F=23.63, p<.001). The cardiovascular risk score based on Framingham risk score differed significantly depending on the measurement period (F=26.18, p<.001), there was no significant difference in the interaction between the two groups and the measurement period (F=0.72, p=.469). Conclusion: It was confirmed that the Individualized education counseling program provided to patients with Percutaneous coronary intervention was effective in increasing the subject's health behavior, but not in lowering the cardiovascular risk.

Purpose: We investigated the effects of a video-based education program for cerebral angiography on patients' state anxiety, uncertainty, nursing care satisfaction, and complications. Methods: The randomized experimental study included patients who underwent cerebral angiography at a university hospital in Bucheon, Gyeonggi-do between January 2023 and August 2023. Patients were assigned to the experimental group (n=50) and the control group (n=48). The program included video- and pamphlet-based education. The intervention included video-based education provided to the experimental group and conventional pamphlet-based education provided to the control group. Data were obtained pre-, post-, and 2-7 days post-intervention. Data were analyzed using the x²-test and the repeated measures analysis of variance test with the SPSS software, version 28.0. Results: The experimental group showed lower levels of state anxiety (x²=4.316, p=.038) and uncertainty (x²=3.974, p=.046) than the control group. However, we observed no significant intergroup differences in satisfaction with nursing care and complication rates. Conclusion: The results suggest that a video-based education program for cerebral angiography can effectively reduce state anxiety and uncertainty in patients undergoing cerebral angiography. Video-aided educational interventions can improve the quality of nursing care with regard to reducing state anxiety and uncertainty in patients who undergo cerebral angiography.

The resource-based relative value scale (RBRVS) compares the value of a medical practice to the consumption of resources, which consist of the work of the physician, practice expenses, and professional liability insurance. At the time of the 2nd revision of RBRVS, the fee for radiological examinations had been reduced due to the high preservation rate. In RBRVS, practice expenses account for most of the compensation of radiological examinations, and physicians' work is relatively undervalued. A new healthcare policy (Moon Jae-In care) consists of the expansion of the National Health Insurance (NHI) coverage, reduction of patient charges for the vulnerable class, and support for catastrophic medical expenses. However, Moon Jae-In care is expected to negatively affect the NHI in Korea financially. The expansion of the insurance coverage for ultrasonography and MRI examinations is a significant part of the Moon Jae-In care, and radiological societies should establish fair compensations for physicians' work within the field of radiology while implementing the Moon Jae-In care.

Purpose: This study aimed to enhance health management and prevention strategies for precocious puberty by comparing the knowledge, motivation, and behaviors related to reducing exposure to endocrine disrupting chemicals (EDCs) between mothers of children with precocious puberty and those of typically developing children. Methods: Participants were 66 mothers of children with precocious puberty from a hospital and 71 mothers of typically developing children from an elementary school. The research questionnaire assessed knowledge of EDCs, motivation, self-efficacy, and behaviors towards reduced exposure to EDCs, in addition to general characteristics of children with precocious puberty. Data analysis utilized descriptive statistics, chi-square tests, t-tests, ANOVA, and Pearson's correlation. Results: There were statistically significant differences in self-efficacy (p=.015) and behavior (p=.001) regarding reduced exposure to EDCs between the two groups. Behaviors toward reduced exposure to EDCs were positively associated with knowledge of EDCs, motivation, and self-efficacy among mothers of children with precocious puberty. Additionally, these behaviors correlated positively with knowledge of EDCs, motivation, self-efficacy, and the child's birth weight and waist circumference among mothers of typically developing children. Conclusion: The results of this study revealed that mothers of children with precocious puberty exhibited less proactive behavior in reducing exposure to EDCs compared to mothers of typical children. Therefore, it is important to foster interest in the impact of environmental factors, beyond characteristic factors, on behaviors aimed at reducing exposure to EDCs.

In this study, we compared the dose using the DAP (Dose Area Product) and Air kerma values across the five most frequently used views in percutaneous coronary intervention, We also evaluated the images based on Contrast to Noise Ratio (CNR) and Signal to Noise Ratio (SNR). Compared to the control group, which did not use magnification, reducing the Field of View (FOV) for magnification resulted in a statistically significant increase in the average DAP and average Air kerma values across all five views. However, no statistically significant difference was observed between the control group and the magnification method that used the Live zoom function. When comparing the CNR of the magnification method using the Live zoom function and the magnification method by reducing the FOV, it was confirmed that the average CNR and average SNR values were significantly improved in all but one of the 15 points. Therefore, it was confirmed that the magnification method using the Live zoom function improved the image quality without increasing the dose.

Purpose : In 1998, there was an outbreak of mumps in Taejon, Korea. We analyzed the monthly incidence, clinical manifestations, and complications during the outbreak and the annual incidence of the recent ten years. Methods : We reviewed the clinical records of 35 mumps patients who had been admitted to Taejon St. Mary's Hospital from January to December, 1998. Results : Mumps was prevalent in summer(from June to August) with 20 cases(57%). Thirthy-three patients(94.3%) received MMR at 15 months of age and no patients received a booster mumps vaccine. The mean age of the mumps patients was 10.5 years-old and the majority of mumps(71%) occurred between 5 and 12 year of age. The male female ratio was 2.2 : 1. The clinical manifestations were swelling of parotid gland(100%), fever (91%), vomiting(77%), abdominal pain(74%) and headache(66%) in order of frequency. Meningitis occurred in 20 cases(57%) and the mean WBC count of CSF was $464{\pm}263/mm^3$. In serology, the mean serum amylase level was $483{\pm}294IU/dL$ and anti-mumps IgM and IgG were positive in 11 and 15 out of 18 cases, respectively. From 1989 to 1997, the mean number of inpatients with mumps was 3.4 per year. Conclusion : We experienced an outbreak of mumps in 1998. It is suggested that there was a primary mumps vaccine failure in Korea and that further studies for vaccine faiure and method of booster mumps vaccine are necessary.
