  • Objectives : This study aims to systematically examine the determinants of the intention to take herbal medicine among individuals with experience in Korean medicine. Methods : This study utilized the 3,245 respondents from the 2020 Korean Medicine Utilization and Herbal Medicine Consumption Survey who reported having used Korean medical services; the responses were selected through a complex sample analysis, and analytics techniques including frequency analysis, Rao-scott chisquare test, and logistic regression were used to analyze the responses. Results : The results of data analysis reveal that the intention to take herbal medicine in the future among these individuals was significantly influenced by factors such as enrollment in private health insurance, the facility environment of Korean medical institutions, and treatment outcomes. Conclusions : Therefore, it is imperative for Korean medical institutions to continuously try reasonable action strategies, including improving medical facilities/environments and building institutional mechanisms among medical staff and members to enhance the quality of Korean medical services. Additionally, the Ministry of Health and Welfare needs to make policy efforts to reduce patients' medical expenses, such as reducing the co-insurance rate in the pilot project of applying health insurance to herbal medicine.

  • Purpose: A positive esophageal margin is encountered in a total gastrectomy not infrequently. The aim of this retrospective review was to evaluate whether a positive esophageal margin predisposes a patient to loco-regional recurrence and whether it has an independent impact on long-term survival. Materials and Methods: A retrospective review of 224 total gastrectomies for adenocarcinomas was undertaken. The Chisquare test was used to determine the statistical significance of differences, and the Kaplan-Meier method was used to calculate survival rates. Significant differences in the survival rates were assessed using the log-rank test, and independent prognostic significance was evaluated using the Cox regression method. Results: The prevalence of esophageal margin involvement was $3.6\%$ (8/224). Univariate analysis showed that advanced stage (stage III/IV), tumor size ($\geq$5 cm), tumor site (whole or upper one-third of the stomach), macroscopic type (Borrmann type 4), esophageal invasion, esophageal margin involvement, lymphatic invasion, and venous invasion affected survival. Multivariate analysis demonstrated that TNM stage, venous invasion, and esophageal margin involvement were the only significant factors influencing the prognosis. All patients with a positive esophageal margin died with metastasis before local recurrence became a problem. A macroscopic proximal distance of more than 6 cm of esophagus was needed to be free of tumors, excluding one exceptional case which involved 15 cm of esophagus. Conclusion: All of the patients with a positive proximal resection margin after a total gastrectomy had advanced disease with a poor prognosis, but they were not predisposed to anastomotic recurrence. Early detection and extended, but reasonable, surgical resection of curable lesions are mandatory to improve the prognosis.

  • Objectives Internet gaming disorder (IGD) is known to be related to stress and the serotonin-transporter-linked polymorphic region (5-HTTLPR) that is known to be associated with stress and has been studied to affect various psychiatric illness outbreaks. We tried to examine the relationship between stress, 5-HTTLPR and IGD. Methods A total of 59 participants with IGD, diagnosed according to the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria and 67 normal controls (NC) were enrolled. The IGD group and the NC were compared using chisquare test and independent sample t-test, and logistic regression analysis was used to examine the relationship between stress, the 5-HTTLPR, and IGD. Results The mean scores for anxiety, impulsivity and stress were significantly higher in the IGD group than in the NC. In addition, there was a significant association between stress and IGD [odds ratio (OR) = 1.172, 95% confidence interval (CI) = 1.008-1.362]. Conclusions This study showed that stress would affect IGD. Therefore, the evaluation and management of stress should be included in the diagnosis and treatment of IGD.

  • Objectives : This study was conducted to investigate the systematic error, such as seasonal change or inadequate food items, in a food frequency questionnaire administered to workers in a Nuclear Power Plant, Korea. Methods : We performed three repeat-tests with 28 subjects on May 13, July 8 and Dec 16, 1992. Our food frequency questionnaire (FFQ) comprised 84 foods organized into 7 food-groups, and was composed of the items of usual intake frequency (8 categories) and the amount per intake (3 or 4 categories) over the previous year. We compared the means of intake frequency and the frequency of the portion-size according to each season using Repeated Measures ANOVA and Pearson's chisquare test with Fisher's exact test. Results : We found the significant seasonal changes of several food items in intake frequency measurement. These items were typical seasonal foods such as mandarin orange, plum and green vegetables, while the single questions consisted of inadequate food items such as thick beef or similar soup and various kimchi products. Significant seasonal changes in portion-size were found in only two items: cooked rice-brown and fresh frozen fishes. Conclusions : The systematic errors observed could caused loss of validity in the FFQ. Consideration should be given for seasonal variation in FFQ survey and methodological concerns are needed to improve the quality for measuring usual diet pattern.

  • Purpose: Dental avulsion injuries have a poor prognosis that largely depends on the immediate steps taken to manage the avulsed tooth. A lack of knowledge about the initial management can lead to tooth loss, with further adverse implications for esthetics, phonetics, and overall growth and function. Hence, the present study aimed to assess parents' knowledge regarding dental avulsion and the variables associated with their knowledge of avulsion injuries. Methods: A series of closed-ended questions on parents' knowledge regarding avulsion, such as immediate management, storage media, handling, and urgency of visiting the dentist, was asked. Univariate associations between the outcomes were assessed using the Pearson chi-square test. The chisquare goodness-of-fit test was used to check whether the sample data were representative of the population. Results: In total, 211 mothers and 149 fathers were included, of whom 46.7% had experienced dental trauma during their own childhood. Sixty-one percent of mothers believed that they knew everything necessary about tooth avulsion and its management. A significant number of participants who thought that they had a good level of knowledge about avulsion chose water, tissue, or paper wrap to transport the tooth, and preferred tap water, alcohol, or antiseptic to clean the avulsed tooth. Conclusions: Both mothers and fathers had poor knowledge about tooth avulsion, indicating that there is an immediate need for educational programs focusing on this issue. Since a substantial proportion of participants believed incorrect information, it is vital to disseminate accurate information.

  • Purpose: The aim of this study was to compare the diagnostic accuracy of previously trained endodontists in the detection of artificially created periapical lesions using cone-beam computed tomography (CBCT) and digital periapical radiography (DPR). Materials and Methods: An ex vivo model using dry skulls was used, in which simulated apical lesions were created and then progressively enlarged using #1/2, #2, #4, and #6 round burs. A total of 11 teeth were included in the study, and 110 images were obtained with CBCT and with an intraoral digital periapical radiographic sensor (Instrumentarium dental, Tuusula, Finland) initially and after each bur was used. Specificity and sensitivity were calculated. All images were evaluated by 10 previously trained, certified endodontists. Agreement was calculated using the kappa coefficient. The accuracy of each method in detecting apical lesions was calculated using the chisquare test. Results: The kappa coefficient between examiners showed low agreement (range, 0.17-0.64). No statistical difference was found between CBCT and DPR in teeth without apical lesions (P=.15). The accuracy for CBCT was significantly higher than for DPR in all corresponding simulated lesions(P<.001). The correct diagnostic rate for CBCT ranged between 56.9% and 73.6%. The greatest difference between CBCT and DPR was seen in the maxillary teeth (CBCT, 71.4%; DPR, 28.6%; P<.01) and multi-rooted teeth (CBCT, 83.3%; DPR, 33.3%; P<.01). Conclusion: CBCT allowed higher accuracy than DPR in detecting simulated lesions for all simulated lesions tested. Endodontists need to be properly trained in interpreting CBCT scans to achieve higher diagnostic accuracy.

  • The purpose of this study is to find factors associated with the preventive health behavior in the daily lives of housewives of a region in Korea, with a hope that knowledge on the health behavior obtained from this study can be of use in promoting practice of good health behavior of the people. The data this study was collected from 672 persons, randomly selected among residents in Wonseong-Dong Chu-nean City and BuanGun, Junbug. Chisquare test, Pearson's C. C., and Stepwise multiple regression are major statistical methods used in this study. Major findings are as fellows: 1) Health behavior of the respondents was found to be related to their characteistics such as residence. age, educational attainments, and standard of living. However, no statistical significant relation has been found between respondent's health behavior and their characteistics such as size of household living together with children or not, yes or no elderly living together. and yes or no Sick family menber. 2) The preventive health behavior of respondents were found to be significantly related to their interests in their own health status. But the association between the practice of certain health behavior and their recognition of their own health status was statistically insignificant. 3) Practice rates of certain preventive health behavior were found different depending their general knowledge on health(P<0.05). 4) Respondents had significantly different preventive health behavior depending on their attitude on health(P<0.001). 5) Degree of contact with mass-media had shown to be significantly associated with preventive health behavior(P<0.001). 6) In the stepwise regression analysis on preventive health behavior. independant variables representing attitude and knowledge on health and contact of mass-media all together explained 20.4 % of the variance of dependent variable.

  • Objectives: This study aimed to evaluate the diet and health status of elderly women according to the family type. Methods: A total of 307 elderly women participated in this study were divided into one of three groups according to their family type: residing with spouse (RSP; n=88), residing with son or daughter (RSD; n=119), and residing alone (RAL; n=100). Chisquare test was used to assess dietary habits and health status of the subjects by the family types. Results: Results demonstrated significant associations between eating regular meals, person preparing meals, coffee intake, and bone fracture experience and family type. Among the three groups, the RSP and RAL groups had a higher percentage for preparing meals by themselves (p<0.001) than the RSD group. The RAL group had a lower percentage for eating regular meals (p<0.01) but a higher percentage for bone fracture experience (p<0.05) than the other groups. There were no significant differences in monthly allowance, self-estimated health status, physical activity, exercise, drinking, and dietary habits such as frequency of consumption of dairy, beans, eggs, fish, meat, fruits, and vegetables among the three groups. Conclusions: The results showed that elderly women residing alone without a son, daughter, or spouse had more diet-related and health problems such as irregular meals and high bone fracture experience. These findings suggested that elderly women residing alone need more attention and support.

  • Background: Meralgia paresthetica (MP) is a mononeuropathy affecting the lateral femoral cutaneous nerve. The disease is often diagnosed clinically, but electrophysiological tests play an important role. The aim of this study is to clarify clinical characteristics of MP as well as the role of sensory nerve conduction study (NCS) in the diagnosis of MP. Methods: Sixty-five consecutive patients with clinical diagnosis of MP between March 2001 and June 2012 were retrospectively reviewed at a single tertiary center. General demographics, clinical characteristics and sensory NCS findings were investigated. Measurements of sensory NCS included the baseline-to-peak amplitude, side-to-side amplitude ratio and the conduction velocity. To compare between the normal and abnormal NCS groups, independent t-tests and chisquare test were performed. Results: Sixty-five patients had male predominance (56.9%) with mean age of $48.4{\pm}13.4$ years (range: 16-75). Seven patients (13.5%) had undergone operation or procedure before the symptom onset. The sensory nerve action potentials were obtainable in 52 (80%) of 65 clinically diagnosed MP patients. Sensory NCS revealed abnormalities in 38 patients (73.1%), and others (n=14, 26.9%) showed normal findings. Between the normal and abnormal NCS groups, there is no statistically significant difference on demographics or clinical features. Conclusions: We clarify the clinical features and sensory NCS findings of MP patients. Due to several limitations of sensory NCS, the diagnosis of MP could be accomplished both clinically and electrophysiologically.
