Purpose: We investigated correlations between the findings of oral examinations and panoramic radiography in order to determine the efficacy of using panoramic radiographs in screening examinations. Methods: This study included patients who visited dental clinics at National Health Insurance Service (NHIS) Ilsan Hospital for checkups during 2009-2015 and underwent panoramic radiographic examinations within 1 year prior to the oral examinations. Among the 48,006 patients who received checkups, 1,091 were included in this study. The data were evaluated using the Cohen kappa and interrater agreement coefficients. Accuracy, sensitivity, and specificity were calculated using data from the panoramic radiographs as true positive diagnoses. Results: The interrater agreement coefficient for occlusal caries was 28.8%, and the Cohen kappa coefficient was 0.043 between the oral and panoramic radiographic examinations. Root caries and subgingival calculus were only found on the radiographs, while gingival inflammation was found only by the oral examinations. The oral examinations had a specificity for detecting occlusal dental caries of 100%, while their sensitivity for proximal dental caries and supragingival calculus was extremely low (14.0% and 18.3%, respectively) compared to the panoramic radiographic examinations. The oral examinations showed a relatively low sensitivity of 66.2% and a specificity of 43.7% in detecting tooth loss compared with panoramic radiography. Conclusions: Panoramic radiography can provide information that is difficult to obtain in oral examinations, such as root caries, furcation involvement, and subgingival calculus, which are factors that can directly affect the survival rate of teeth. It therefore seems reasonable and necessary to add panoramic radiography to large-scale health checkup programs such as that provided by the NHIS.

Sitting position upper extremity X-ray examinations (SUEX) is the most widely used patient positioning method for upper extremity X-ray examinations. For this method, the radiation dose is considerable for relatively less interesting organs. We investigated whether patients need to wear the apron during the examination or not. We also studied the examination methods which can reduce the radiation dose. The results showed that radiation dose was reduced as the distance of source to patient becomes longer and the thickness of object grows higher.

The use of CT examinations is increasing rapidly and radiation dose from CT examinations is much higher than other diagnostic radiography examinations including general radiography and mammography. DRLs used to optimize the radiation dose of patients by diagnostic radiology in each country. The objective of this study was to investigate and to analyze the status of DRLs from CT examinations in domestic and other countries. In other countries, DRLs were set for each age group and each examination considering the medical situation of each country. In Korea, DRLs were set for adults and children in 2017. For adults, DRLs were set for 13 examinations. Reported DLP values were 1119, 297, $472mGy{\cdot}cm$ for head, chest and abdomen pelvis examination, respectively. For children, DRLs were set for head examinations. Reported DLP values were 298 (0~1 years), 404 (2~5 years), 494 (6~10 years), 1,088 (11~15 years) $mGy{\cdot}cm$. DRLs of Korea were similar to other countries for head examinations. For chest examinations and abdomen pelvis examinations were relatively lower than other countries. As a major reason for relatively low radiation dose, it is considered to contribute the activity and management of medical radiation safety at national level.

The purpose of this study was to evaluate the degree of heterophoria variations according to visual fatigue induced by increasing number of examinations while repeating binocular vision examinations. Twenty - one adults in their twenties who had no heterotropia other eye disease or systemic disease underwent binocular vision examinations. As the examinations progressed, the degree of heterophoria increased in both orthophoria and heterophoria. When the distance examinations was repeated 5 times, orthophoria increased degree of $1.56{\Delta}$ heterophoria. and heterophoria increased degree of $1.63{\Delta}$ heterophoria. When the near examinations was repeated 5 times, orthophoria increased degree of $1.78{\Delta}$ heterophoria. and heterophoria increased degree of $2{\Delta}$ heterophoria.. As the number of examinations increased, the result gradually deviated from the normal range as visual fatigue increased. The degree of the variation is judged to be enough to make the wrong prescription in the clinic. In conclusion, it was found that the binocular vision examinations should be conducted more accurately and promptly.

This study analyzed the current status of MRI (frequency, amount of treatment) based on the history of application of the MRI health insurance benefit standard and health insurance claim data. MRI examinations began as a health insurance benefit in 2005. In 2005, the indications were restricted for some diseases, but coverage for benefits in 2010, 2013, 2016, and 2018 was expanded. In 2021, the Ministry of Health and Welfare decided to apply health insurance for all MRI examinations. From 2010 to 2017, the number of MRI examinations increased by 86.7% in 2017 compared to 2010, and the amount of treatment increased by 53.5%. According to general characteristics, the number of MRI examinations was higher in women than in men. By age, the number of examinations was the highest among ages 70-79. Outpatient examinations were more frequent than inpatient examinations, and the number of examinations in the tertiary hospitals was the highest among the types of hospitals. The number of brain MRI examinations was the highest in each exam site. In December 2013, the standard of MRI was expanded for heart disease and Crohn's disease, the number of cardiac MRI and abdominal MRI examinations increased in 2014 compared to 2013. However, the number of examinations is small and not associate with the disease, it would be difficult to say that it affected the increase in the total number of MRI examinations. To assess health insurance sustainability and policy effectiveness, monitoring will be necessary.

Objectives: The purpose of this study was to investigate the opinions of experts on abdominal examinations in Korean Medicine included in the curriculum of the College of Korean Medicine. Methods: Among Korean doctors, 14 experts on abdominal examinations were interviewed; the experts included 9 professors of Korean internal medicine, 1 expert in diagnostics of Korean Medicine, 1 primary care Korean medicine doctor, and 3 executives of a (former) Korean association of the abdomen. The interview consisted of questions regarding recognition of the clinical importance of abdominal examinations, how to perform abdominal examinations, the most frequent abdominal examination findings encountered in clinical practice, and the definition of some of the abdominal examination findings. Results: Most interviewees recognized abdominal examinations as important and used them in clinical practice. Opinions on additions and corrections were collected regarding observation items, posture, method, and order during abdominal examinations. Abdominal examination findings that were common clinically were abdominal fullness (腹滿), epigastric stuffness (心下痞鞕), abdominal tenderness, epigastric fullness (心下滿), and rib distention (胸脇苦滿). The answers to the question related to the definitions of abdominal examination findings included consent and supplementary opinions regarding definitions of deficiency-excess, cold-heat, abdominal tenderness, tension of abdominal muscles, succession sounds, and borborygmus; these were mainly selected based on abdominal symptoms that are highly quantifiable. Conclusions: In the future, based on the results of this study, additional research related to the drafting of a standard abdominal examination in Korean medicine should be conducted to provide an opportunity to increase the reliability of Korean medicine diagnosis.

This study has been conducted, on the reservation of specific examinations during seven months starting from June 1999 and ending December as the Group I for these of one stop service and as the Group II for those of existing direct reservation made by patients or patrons, to understand the differences between the two groups. The survey was extended to the patients visiting specific departments of K hospital with sample sizes of 154 for the Group I and 155 for the Group II. The findings of the survey are as follows: First, as the general characteristics of the sample, male patients account for 67% of the total and female patients 33%, with the former twice as large as the latter. The average age of the patients is 51, indicating relatively high level. By the geographical area of residence, metropolitan area is 80.7% and the other area 19.3%, showing most of the patients are from metropolitan area. The general characteristics do not have statistical significance between the Group I and the Group II(p>0.05). Second, regarding the ratio by the number of examinations, the Group I shows 37.0% for one examination and 63.0% for two examinations, while the Group IT indicates 30.3% for one examination and 69.7% for two examinations. The populations by the number of examinations do not have statistical difference between the two Groups(p>0.05). Third, regarding the time required for the reservation of examinations by the number of examinations, the Group I shows 9.8 minutes for one examination and 19.8 minutes for two examinations, with the average of 16.1 minutes. The Group IT indicates 19 minutes for one examinations and 25.7 minutes for two examinations, with the average of 23.7 minutes. Though the time required for the reservation by the number of examinations do not have statistical significance, the time required for the Group I was shortened. Fourth, regarding the time required for the reservation of examinations by the age range of patients, the Group I shows 21.7 minutes for 70-79 years of age, 17.5 minutes for 60-00 years of age, and 15.2 minutes for 30-39 years of age. The Group II indicates 27.2 minutes for 70-79 years of age, 26.3 minutes for 60-69 years of age, 24.4 minutes for 50-59 years of age, and 22.4 minutes for 30-39 years of age. The time required for the reservation gets longer as the age range moves up, and has statistical significance (p<0.05). Fifth, regarding the ratio by the range of time of required for reservation, the Group I shows 41.6% for 11-20 minutes, and 38.3% for 1-10 minutes, while the Group II indicates 43.9% for 11-20 minutes, 29% for 21-30 minutes, and 14.2% for 31-40 minutes. Statistical significance is revealed (p=0.001). Sixth, concerning the length of movement course by the number of examinations, the Group I shows 37 meters regardless of the number of examinations. The Group II indicates an average of 188 meters for one examination and 189 meters for two examinations, with the difference 151 meters between the Groups, and representing statistical significance (p=0.001). Based on the above findings. one-stop service contributes to the reduction of both the time and the movement course and therefore is considered to be beneficial to the patients, and the improve the efficiency of the hospitals in terms of the space and the time.

Purpose: The aim of this study was to investigate the use and acceptance of digital radiographic examinations by Brazilian dental practitioners in daily practice and to evaluate the advances that have occurred over the past 5 years. Materials and Methods: Dental practitioners enrolled in extension courses at the Piracicaba Dental School, University of Campinas, Brazil, responded to a self­administered questionnaire in the years 2011 and 2015. They were asked about sociodemographic factors and their knowledge and use of digital radiographic examinations. Descriptive analysis was performed, as well as the chi-square and Fisher exact tests, with a significance level of 5% (${\alpha}=0.05$). results: A total of 181 participants responded to the questionnaire in the years 2011 and 2015. Most of the respondents worked in private practice, had graduated within the last 5 years, and were between 20 and 30 years old. In 2011, 55.6% of respondents reported having ever used digital radiographic examinations, while in 2015 this number increased significantly to 85.4% (p<.0001), out of which 71.4% preferred it to conventional images. Moreover, 21.4% of respondents reported having used digital radiographic examinations for more than 3 years. A significant increase in use of intraoral digital radiography (p = 0.0316) was observed in 2015. In both years, image quality and high cost were indicated, respectively, as the main advantage and disadvantage of digital radiographic examinations. conclusion: This study showed that digital radiology has become more common in Brazil over the past 5 years. Most of the Brazilian dental practitioners evaluated in 2015 used digital radiographic examinations.

Purpose: This study compared the pain-relieving effects of human milk, sucrose, and distilled water during examinations for retinopathy of prematurity. Methods: Forty-five preterm infants were randomly assigned to receive a pacifier dipped in one of three solutions: human milk (n=14), 24% sucrose (n=15), or distilled water (n=16), 2 minutes before an eye examination. Their pain score, pulse rate, and oxygen saturation were measured at three time points: 5 minutes before the examination, 30 seconds after speculum introduction, and 2 minutes after the examination. Results: The infants' mean gestational age and weight at birth were $33.1{\pm}2.1$ weeks and $1,842{\pm}470g$, respectively. There were no between-group differences in pain relief during the eye examination. The pain score significantly increased both during (p<.001) and after the examinations (p=.003). Oxygen saturation decreased during the examinations (p<.001); however, the infants in the 24% sucrose group showed higher oxygen saturation (p=.047) during the examinations than the infants in the other groups. Conclusion: Sucking on a pacifier dipped in human milk or 24% sucrose did not reduce the pain associated with eye examinations in preterm infants. Pacifiers dipped in sucrose can be used to maintain better oxygen saturation during these examinations.

From March 1986 to June 1990, the percutaneous Fine Needle Aspiration Biopsy[FNAB] of 102 thoracic lesions were performed with Westcott needle [slotted 20G or 22G thin needle], for the purpose of identifying and diagnosing thoracic lesions. There were 94 lung lesions [67 malignant tumors, 27 benign lesions] and 8 mediastinal and chest wall lesions. The results of FNAB were compared with sputum cytology and bronchoscopic examinations. The sputum cytologic examinations were performed in 54 cases of malignant lung tumor and the malignant cell was found at the 18 cases [33%]. We bronchoscopic examinations were performed in 24 cases and the malignant cell was found at the 12 cases [55%]. The positive diagnostic rate of malignancy was 100% by FNAB. Among them, 55 cases [82%] were diagnosed by cytologic examinations and 43 cases[64%] by both. The specific diagnoses for benign lung lesions in 15 cases[55%] and for mediastinal and chest well lesions in 5 cases[62%]. The 7 patients[6.9%] developed the pneumothorax and 5 of them required the treatment. Therefore, the FNAB of thoracic lesions may be a preferred diagnostic method because of its safety, simplicity and accuracy.
