The purpose of this study is to compar self-reported fatigue and fatigue-regulating behaviors of rheumatoid arthritic patients and normal persons. This study collected the data from 75 rheumatoid arthritic patents visited the departments of internal medicine or orthopedics of four general hospitals T-city and K-city by means of direct interview and questionnaires. in this study also collected data from 75 normal persons who had not been exposed to any other disease in T-city and K-city by means of direct interviews anti questionnaires which were conducted by two trained nurses. This experiment was conducted from August 1, 1998 to October 15, 1998. This study used both MAP(Multi-Dimentional Assessment of Fatigue) developed by Belza(1995) to measure fatigue and the measurement developed by Kwon, Young-Eun to investigate fatigue regulating behaviors. The collected materials were analyzed by means of descriptive statistics, t-test, and the ANCOVA according to the SPSS PC+ program. The findings are as follows : 1. There was the statistically significant difference(t =5.07, p=.000), between rheumatoid arthritic patients(32.76 points) and normal persons(25.81 points) in t-test comparison by group about fatigue. A fatigue degree of rheumatoid arthritic patient group was high in five kinds of lower realms such as common fatigue degree, fatigue severity to be experienced, distress due to fatigue, daily fatigue degree, and fatigue timing at the last week by dimension. 2. There was the significant difference in the number of fatigue-regulating behaviors between rheumatoid of fatigue arthritic patients(9.37 times) and normal persons (8.15 times), but there wasn't any significant difference in the efficiency between rheumatoid arthritic patients(2.85 points) and normal persons (2.78 points) This research suggests two kinds of things as follows : 1. It is necessary to develop an educational program for improving efficiency of fatigue-regulating behaviors as well as some nursing arbitration measures for reducing fatigue of rheumatoid arthritic patients. 2. It is necessary for the future studies to continuously grasp characteristics of fatigue by gender variable by selecting more rheumatoid arthritic male patients.

In this study, we propose an automated smile analysis system for self smile training. The proposed system detects the face area from the input image with the AdaBoost algorithm, followed by identifying facial features based on the face shape model generated by using an ASM(active shpae model). Once facial features are identified, the lip line and teeth area necessary for smile analysis are detected. It is necessary to judge the relationship between the lip line and teeth for smiling degree analysis, and to this end, the second differentiation of the teeth image is carried out, and then individual the teeth areas are identified by means of histogram projection on the vertical axis and horizontal axis. An analysis of the lip line and individual the teeth areas allows for an automated analysis of smiling degree of users, enabling users to check their smiling degree on a real time basis. The developed system in this study exhibited an error of 8.6% or below, compared to previous smile analysis results released by dental clinics for smile training, and it is expected to be used directly by users for smile training.

In this study, using the tasks related trigonometric functions, the degree of high school students' understanding of the function concept was examined through the level of Hitt(1998). First, the degree of the students' understanding was classified by level, then the concept understanding was reclassified by the process or the object. As a result, high school students' concept understanding showed incompleteness in three stages. It was possible to know that the process in the interpretation of the graph is the main perspective, and the operation of algebraic representation is regarded as important. Based on these results, it seems necessary to study the teaching-learning method which can understand trigonometric functions from various perspectives. It seems necessary to study a lesson model that can reach function concept's understanding level 5 that maintains consistency between problem solving and representation system.

Since most of the first witnesses of cardiac arrest in clinical settings are nurses, the ability to perform CPR is important. The purpose of this study is to provide basic data for developing education that strengthens CPR performance in the future by examining inactive nurses' CPR knowledge, attitude, performance confidence, device discomfort, continued use intention, and educational achievement. The final subjects of this study were 88 inactive nurses residing in B city. The study period was from June 23, 2020 to December 24, 2020. The collected data were analyzed by descriptive statistics and Pearson correlation using SPSS WIN 24.0 program. After obtaining the subject's consent for the study, an inactive nurse who understood the purpose of the study and voluntarily consented to the study participated. To investigate the perception of experience, the subjects watched 360-degree virtual reality contents about CPR in the hospital using HMD. The data of this study were analyzed using SPSS WIN 22.0.program. As a result of this 360-degree study on CPR in the hospital, the average score for the inactive nurses on CPR knowledge was 12.70±3.43, the average score for performance confidence was 6.04±2.45, and the average score for attitude was 4.63±0.80. As a result of experience recognition of 360-degree virtual reality contents for CPR in hospitals, the average score for device discomfort was 4.01±0.94, the average score for continued use intention was 2.07±0.85, and the average score for educational achievement was 2.11±0.79. As a result of correlation analysis, educational achievement and continued use intention were significantly positively correlated (r=.77, p<.001). Based on the results of this study, in order to strengthen the CPR performance capability of inactive nurses in emergency situations, it is necessary to increase CPR knowledge and confidence in performing CPR, and to cultivate a positive attitude toward performing CPR. In addition, it is necessary to implement CPR simulation education based on patient cases by applying content that considers educational achievement and continuous use intention.

It is positively necessary to study on the stiffness of a 13degree-type impact tester in order to improve the fracture prediction of impact testing in wheels using FE(finite-element) analysis. The 13degree-type impact tester consists of an impact striker, a wheel fixer, a steel plate, and four cylindrical rubbers. Important parts of the tester are the steel plate and four cylindrical rubbers which play a role of absorbing impact energy during impact testing. Because of these buffers, the RF(reaction force) variation of the lower part in the 13degree-type impact tester showed the tendency like a damped harmony oscillation during impact testing. In order to investigate the stiffness of a 13degree-type impact tester, this work measured each stiffness of a steel plate and cylindrical rubbers. The stiffness of a cylindrical rubber was measured using a compressive tester. On the other hand, the stiffness of a steel plate was predicted by simulating experimental method using FE analysis.

This study examined the awareness, satisfaction, and usage patterns of 257 elementary school teachers for food labeling in Busan. The survey was conducted from April 15 to June 20, 2020, by questionnaires. The perception degree of food labeling was higher in female teachers than in male teachers and did not differ significantly among age groups. The score of the understanding degree was highest in their 20s and lowest in their 30s. The degree demand in their 50s was higher than in their 30s and 40s. The reliability degree in their 20s was higher than that of those in their 40s and 50s. The verification degree and satisfaction degree did not differ significantly with age or gender. The primary reason to check food labeling was 'to confirm harmful additives (31.9%)'. Among those in their 20s and 30s, the major reason for reviewing nutrition labeling was 'nutrient', while it was 'health improvement' was most important in those in their 40s and 50s. Of the subjects, 31.1% reported that the reason for the difficulty in understanding the label was 'various forms and the small letters'. The demand for the content was highest in trans fats. Apporximately 32.3% of the teachers were educated for food labeling; 42.4% of them taught food labeling, and 62.7% of them recognized the necessity of food labeling teaching. A correlation was observed between the demand for food labeling and understanding (r=0.586). Therefore, preparing education programs for teachers according to gender and age group and developing food additives-related programs will be necessary for strengthening the teachers' ability to manage their dietary life and educate students.
