This study was to find out whether the rendering screen difference affect to measuring distance in a CAD program according to three types of CAD programs. Materials and methods: The model presented in ISO 12836 for dental scanner evaluation was reduced by 70%. This model was repeatedly scanned 15times using Trios II (3Shape, Denmark). Using the output STL file, 3Shape CAD, inLab 15, and ExoCAD programs were used to measure the horizontal distance (H) and vertical distance (V) between adjacent point angle, and for each experiment, three groups were set according to the CAD program type. Statistical analysis was performed using One-way ANOVA test and post hoc was performed using Dunnett T3 test. Results: In the horizontal and vertical distance measurement, there was no difference in the average of the measured values between the three groups according to the CAD program (P>.05). Conclusion: There were no effect of the difference in the rendering screen in the horizontal and vertical linear distance measurements of the inlay model on the dental CAD program.

BACKGROUND: The author surveyed and analyzed the changes of perception and satisfaction about family medicine. So that the outcome may bring us a reference to advance family medicine more. METHODS: 247 in and out patients in one general hospital in Seoul were surveyed by the questionnaire from July 26, 2000 to June 20. The date was analyzed statistically by SAS program. RESULTS: As for the knowledge of family medicine, 61.5% of the patients answered that they knew what it is, and the most of them, 54%, via medical institution. The office workers, married , and highly educated people tend to know more about family medicine (P<0.05). As for attitude, 68% of the group answered that family medicine is necessary, because "family medicine doctors give proper advice and consult through out all fields of medicine"(58.8%). As for the preference so prirate doctor, 56.7% of the group answered that they would register for family medicine clinic, and students and office workers are fond of family medicine(P<0.05). As for the satisfaction, 34.4% were ever been to family medicine clinic, and 35.5% out of them were dissatisfied, mainly due to the lack of knowledge of physicians about their diseases(70.1%). CONCLUSION: The perception of family medicine are still scanty compared to the old studies.

Objective:
Mental health problems such as anxiety, panic, and depression have been exacerbated by the coronavirus disease-2019 (COVID-19). This study aimed to compare the symptom severities and overall function before and during the COVID-19 pandemic among patients with panic disorder (PD) seeking treatment compared to healthy controls (HCs).
Methods:
Baseline data were collected from the two groups (patients with PD and HCs) in two separate periods: before COVID-19 (Jan 2016–Dec 2019) and during COVID-19 (Mar 2020–Jul 2022). A total 453 participants (before COVID-19: 246 [139 patients with PD and 107 HCs], during COVID-19: 207 [86 patients with PD and 121 HCs]) was included. Scales for panic and depressive symptoms and overall function were administered. Additionally, network analyses were performed to compare the two groups within the patients with PD.
Results:
The results of two-way analysis of variance analyses showed that patients with PD enrolled during COVID-19 showed higher levels of interoceptive fear and lower overall functioning. In addition, a network comparison test revealed that a significantly high strength and expected influence for agoraphobia and avoidance in patients with PD during COVID-19.
Conclusion
This study suggested that the overall function could have worsened, and the importance of agoraphobia and avoidance as a central symptom may have increased in patients with PD seeking treatment during COVID-19.

BACKGROUND:
Superficial fungal infections, including dermatophyte infection and cutaneous candidiasis, are common and affect more than 25% of the population worldwide.
OBJECTIVE:
The aim of this study was to investigate the recent clinical and mycological characteristics of dermatophytosis and cutaneous candidiasis in southeastern Korea.
METHODS:
Of 20,413 patients with dermatophyte infection, cutaneous candidiasis, or suspected fungal infection, 8,106 who were culture positive for infection were retrospectively evaluated using their medical records.
RESULTS:
The annual incidence rate of fungal infection tended to be constant. Such infections were more common in men than in women. Fungal infections most commonly occurred in patients in their 50s and in August. The most common clinical type of superficial fungal infections was tinea pedis. The most common causative fungus of superficial fungal infections was Trichophyton rubrum.
CONCLUSION
This study provides useful information on the clinical and mycological characteristics of fungal infections in southeastern Korea in recent years.

BACKGROUND/AIMS: Protein induced by vitamin K absence or antagonist-II (PIVKA-II), also known as des-carboxyprothrombin (DCP), can be used as an alternative tool to alpha-fetoprotein (AFP) for surveillance of hepatocellular carcinoma (HCC). The aims of the present study were to compare PIVKA-II levels between the patients with HCC and patients with non-HCC chronic liver disease, to evaluate the correlation of PIVKA-II and AFP in HCC patients, and finally to estimate the optimal cut-off value for PIVKA-II for the diagnosis of HCC with using the receiver operating characteristic (ROC) curve. METHODS: A total of 227 consecutive patients with HCC (n=42) or chronic liver disease (n=185) were enrolled in this study. HCC was diagnosed histologically or by imaging such as computed tomography, magnetic resonance imaging or angiography. The serum PIVKA-II and AFP levels were measured by electrochemiluminoimmunoassay with using the Haicatch PIVKA-II kit and by immunoradiometric assay, respectively. RESULTS: The PIVKA-II level in the HCC patients was significantly higher than the non-HCC chronic liver disease patients (903.0+/-1156.7 vs. 111.7+/-211.0 mAU/ mL, respectively, P<0.01). PIVKA-II and AFP showed a statistical correlation in HCC patients (r=0.46, P<0.01). The sensitivity and specificity of PIVKA-II for the diagnosis of HCC were 66.7% and 74.1%, respectively, and when tasted together with AFP, the sensitivity was increased by 85.7%. For the ROC curve of PIVKA-II in HCC patients, the specificity of a 250 mAU/mL level of PIVKA-II was 95%. CONCLUSIONS: PIVKA-II was as useful surveillance tool for differentiating HCC from chronic liver disease, and a PIVKA-II value of 250 mAU/ mL was proposed as a significant cut-off value for diagnosis of hepatocellular carcinoma.

Psychiatry Investigation 2020;17(10):967-975
Objective:
The brain-derived neurotrophic factor (BDNF) Val66Met (rs6265) polymorphism is suggested to be associated with the pathophysiology of anxiety disorders, including panic disorder (PD). Although the fronto-limbic white matter (WM) microstructures have been investigated, the corpus callosum (CC) has not yet been studied regarding its relationship with BDNF Val66Met polymorphism in PD.
Methods:
Ninety-five PD patients were enrolled. The Neuroticism, the Anxiety Sensitivity Inventory-Revised, Panic Disorder Severity Scale, and Beck Depression Inventory-II (BDI-II) were administered. Voxel-wise statistical analysis of diffusion tensor imaging data was performed within the CC regions using Tract-Based Spatial Statistics.
Results:
The GG genotype in BDNF Val66Met polymorphism has significantly higher fractional anisotropy (FA) values of the body and splenium of the CC, neuroticism and depressive symptom scale scores than the non-GG genotype in PD. The FA values of the body of the CC in the two groups were significantly different independent of age, sex, neuroticism, and BDI-II.
Conclusion
Our findings demonstrate that the BDNF Val66Met polymorphism is associated with WM connectivity of the body and splenium of the CC, and may be related to neuroticism and depressive symptoms in PD. Additionally, the CC connectivity according to BDNF polymorphism may play a role in the pathophysiology of PD.
