Purpose : To implement the database system of oral and maxillofacial radiological images using a commercial medical image management software with personally developed classification code. Materials and methods : The image database was built using a slightly modified commercial medical image management software, Dr. Image v.2.1 (Bit Computer Co., Korea). The function of wild card '*' was added to the search function of this program. Diagnosis classification codes were written as the number at the first three digits, and radiographic technique classification codes as the alphabet right after the diagnosis code. 449 radiological films of 218 cases from January, 2000 to December, 2000, which had been specially stored for the demonstration and education at Dept. of OMF Radiology of Dankook University Dental Hospital, were scanned with each patient information. Results: Cases could be efficiently accessed and analyzed by using the classification code. Search and statistics results were easily obtained according to sex, age, disease diagnosis and radiographic technique. Conclusion : Efficient image management was possible with this image database system. Application of this system to other departments or personal image management can be made possible by utilizing the appropriate classification code system.

Vickers hardness is an important material in the design and reliability is required. Therefore, these values are very important as the basic data for design, manufacture and development, and the identification of quantitative probability distribution characteristics such as mean and dispersion is a very important parameter in design. In this study, Vickers hardness was measured after artificially heat-treated in the temperature range 753K, where chrome depletion near the grain boundary occurred for three kinds of stainless steels, and the Vickers hardness were evaluated. From the results, Vickers hardness increased with increasing heat treatment temperature. In Weibull distribution for Vickers hardness, the dispersion of STS310S at 813K and 873K was small, and the dispersion of STS316L at 753K, 933K and 993K was small. Also, STS347H exhibited the lowest dispersion at 753K in three kinds of stainless steels. The scale parameter increased with increasing heat treatment temperature in three kinds of stainless steels.

Objectives: This study investigated the effect of physical activity of adult Korean males on the prevalence of diabetes mellitus. Methods: This cross-sectional study used the raw data from the 2017 Community Health Survey. The subjects of this study were 74,494 men aged 19-64 years old. The data was analyzed applying the complex sampling design and using SPSS 23.0 Program. Descriptive statistics, Rao-Scott Chi-square tests and multiple logistic regression analysis were all performed. Results: The prevalence of diabetes mellitus was 6.4%. The walking activity was 58.5% and the over moderate intensity physical activity was 27.5%. After adjusting for age, marital status, educational level, household monthly income, drinking and smoking status, and BMI, those subjects without moderate intensity physical activity had a 1.14 times higher prevalence of diabetes mellitus (95% CI = 1.05-1.24) than those men with moderate intensity physical activity. Conclusion: In order to decrease the prevalence of diabetes mellitus among adult men, regular physical activities over a moderate intensity level should be emphasized and encouraged in daily life.

Purpose: The purpose of this study was to investigate the effects of constraint-induced (CI) movement using self-efficacy on U/E function of chronic hemiplegic patients. CI movement discourages the use of the unaffected U/E, combined with intensive training of the affected U/E. Method: A non-equivalent pretest-posttest design was used. Study subjects were 40 hemiplegic patients conveniently selected from 2 different community health centers. The experimental subjects participated in the CI movement program for 6 hours daily over a period of two weeks. The exercises for affected U/E consisted of warming up, main exercise and ADL practice. To encourage the participants' behaviors self-efficacy enhancing strategies were used, which included performance accomplishment, vicarious experience, verbal persuasion and emotional arousal. Result: After 2 weeks of treatment, the grip power, pinch power, wrist flexion/extension, elbow flexion, and shoulder flexion/extension were significantly higher in the experimental subjects than in the control subjects. However, there was no significant difference in hand functions of the two groups. Conclusion: The above results show that the constraint-induced movement using self-efficacy could be an effective nursing intervention for improving U/E function of chronic hemiplegic patients. Long term studies are needed to determine the lasting effects of constraint-induced movement.

Purpose: This study was performed to verify the effect of Tai Chi exercise on patients with rheumatoid arthritis particularly their level of pain, fatigue, sense of balance and daily lift performance(ADL). Method: It employed a non-equivalent control group pre- and post-test design. The research instruments used in this study were pain, fatigue, sense of balance and ADL. Thirty-two patients in the experimental group carried out 50 minutes of Tai Chi exercise for 12 weeks, and 29 patients in the control group did not. Before and after the experiment, both groups were tested for pain, fatigue, sense of balance and ADL. Collected data were processed using the SPSS/WIN 10.0 program analyzed by the frequency, percentage, $x^2-test$, and t-test. Results: Pain and fatigue significantly decreased in the experimental group. However the improvement in ADL of the rheumatoid arthritis patients was not statistically significant but their sense of balance was enhanced significantly. Conclusion: Tai Chi exercise is an effective nursing intervention that can be used for rheumatoid arthritis patients.

This study aims to measure the emotional effects of pet plants, which have become popular in recent years. A questionnaire regarding perceptions of these indoor plants was administered to 78 university students. Thirty of these students took care of two species of pet plants for 90 days, and the emotional effects of this exercise were determined based on the type of words used in their daily records. The questionnaire results showed that the general recognition of emotional effects was low, though awareness of the term "pet plants" was high. However, after gardening for 90 days, participants began to consider their pet plants friends or family members, noting feelings of affection and sympathy in their daily writeups. These participants also experienced positive changes in their emotional well-being, including feelings of joy, hope, relaxation, confidence, and accomplishment. This study argues that pet plants can have positive effects on emotional stability and suggests that their adoption would be beneficial to humanity at large.

This Study attempted to comprehend difference between hiker and non-hiker's sense of place value at Namhansanseong Provincial Park. Especially, it was analyzed after visitors, who were divided into local residents & tourists and first time visitors & repeat visitors. Out of 600 visitors, who were over 19 years old, participated in the survey, 587 responses were used for data analysis. Consequently, Sense of place value at Namhansanseong Provincial Park were classified into three factors: Health Culture, Ecology Environment, and Connectedness. Hikers feel higher value on promotion of health, relaxation, environment than non-hikers. Among hikers, local residents feel higher value on ecology environment and connectedness than tourists. Among non-hikers, however, they have no difference between local residents and tourists, only repeat visitors and first time visitors. On this result, possibility of resident participation management on natural environment and trail was considered, and when the program, which is for raising cultural and traditional value, would develop, increasing number of repeat visitor should be considered as a high priority.

The present study intends to find a proper solution for the estimation of the physical behaviors of enlarged piles through a combination of small-scale laboratory tests and a hybrid computational predictive intelligence process. In the first step, experimental program is completed considering various critical influential factors. The results of the best multilayer perceptron (MLP)-based predictive network was implemented through three mathematical-based solutions of dragonfly algorithm (DA), whale optimization algorithm (WOA), and ant lion optimization (ALO). Three proposed models, after convergence analysis, suggested excellent performance. These analyses varied based on neurons number (e.g., in the basis MLP hidden layer) and of course, the level of its complexity. The training R² results of the best hybrid structure of DA-MLP, WOA-MLP, and ALO-MLP were 0.996, 0.996, and 0.998 where the testing R² was 0.995, 0.985, and 0.998, respectively. Similarly, the training RMSE of 0.046, 0.051, and 0.034 were obtained for the training and testing datasets of DA-MLP, WOA-MLP, and ALO-MLP techniques, while the testing RMSE of 0.088, 0.053, and 0.053, respectively. This obtained result demonstrates the excellent prediction from the optimized structure of the proposed models if only population sensitivity analysis performs. Indeed, the ALO-MLP was slightly better than WOA-MLP and DA-MLP methods.
