Background & Objectives: This study aimed to examine the relationship between subjective health perception and health behaviors among adolescents, utilizing raw data from the 8th Korea National Health and Nutrition Examination Survey (2019-2021) while distinguishing between genders. Methods: The study employed data from the 8th Korea National Health and Nutrition Examination Survey (2019-2020), recruiting students from 1st to 3rd grades in middle and high schools nationwide. Through population stratification, sample distribution, and sampling stages, a final sample of 1,065 adolescents aged 12 to 18 years was selected. The collected data were analyzed using SPSS 28.0 (IBM Corp., Armonk, NY, USA) at a significance level of .05. Results: Regarding the general characteristics of the subjects, no statistically significant differences were observed among male students based on school, family structure, and income. However, among female students, a significant difference in subjective health perception was noted, with higher perception among high school students compared to middle school students (p=.001). Significant differences in health behaviors were identified based on family structure for male adolescents, where those living with both parents exhibited more health-promoting behaviors than single-parent adolescents (p=.011). However, no significant difference was observed among female adolescents. In terms of health behaviors related to gender, regular exercise was found to significantly impact subjective health perception in male adolescents (p=.013), while breakfast habits were identified as significant influencers for female adolescents (p<.001). Conclusions: This study revealed gender differences in subjective health perception and health behaviors among adolescents. Based on these findings, there is a perceived need for the development of health promotion programs tailored to the unique needs of male and female adolescents.

Purpose: This study was conducted to examine the status of dietary behavior and its association with study-related factors in middle school students. Methods: Study-related factors, dietary habit score and dietary behaviors were surveyed by questionnaire and then analyzed. A total of 580 students in some middle schools in Gyeonggi-do participated in this study. Collected data were analyzed using SPSS for windows Ver. 22.0. Results: 71.3% of the subjects slept for 6 ~ 8 hours, and the studying time outside of school was the highest (2 ~ 4 hours). The highest score for stress from studying by private lessons or academies was 'seldom stressed', with higher stress being observed in male students than female students. The average dietary habit score was 3.69 in male students and 3.62 in female students. The highest average time for meal eating was 10 ~ 20 minutes, with shorter times being observed for male students than female students. Eating meals was regular in most students and the highest number of snack eating was 1 ~ 2 times a day. For dietary behaviors by study-related factors, students with more than 2 hours of studying time outside of school showed higher dietary habit scores than those with less than 2 hours, who showed significantly higher rates of eating 2 meals a day. As the sleeping hours and daily average studying hours increased, the rate of regular meal eating increased significantly. Conclusion: The students showed good, above average dietary behaviors, but gender differences in study-related factors and dietary behaviors. Moreover, the sleeping hours and the studying time outside of school were correlated with dietary habit scores and dietary behaviors. Thus, continuous and systematic education for proper dietary behavior is needed along with greater interest in students with problems of study-related factors, particularly those due to study burden.

Objective : The purpose of this study was to examine the relationship between bone mineral density (BMD) and the metabolic syndrome. Method : We conducted a cross-sectional study of 1204 adults(males: 364 females: 840) in a general hospital health promotion center. They were grouped into the normal and lower BMD group according to bone loss(osteopenia, osteoporosis), as determined by duel energy X-ray absorptiometery(DEXA). We analyzed the association between BMD and metabolic syndrome by multiple logistic regression analysis. After adjustment for age, weight, alcohol intake, smoking, regular exercise, regular intake of meals, and menopausal status, odds ratios for the prevalence of the metabolic syndrome by gender were calculated for lower BMD. Results : After adjustment for the effect of potential covariates, the prevalence of metabolic syndrome was associated with bone loss in men(p<0.001). If the odds ratio of normal group is 1.00, then that of the lower BMD group is 3.07(95% CI=1.83-5.16). The prevalence of metabolic alterations fitting the criteria of metabolic syndrome was significantly decreased in High BMI, Low HDL in men and in High BMI in women(p<0.05). Conclusions : This study shows that BMD was associated with metabolic syndrome. Further studies needed to obtain evidence concerning the association between BMD and metabolic syndrome.

The purpose of this study was to compare dietary and lifestyle habits in middle-aged women based on their self-perceived health-related physical fitness (SPF) level as well as investigate the effects of dietary and lifestyle habits on SPF. The study subjects were divided into two groups, 'High' group (${\geq}3.2$, n=64) and 'Low' group (<3.2, n=69), based on average SPF value (3.2). Women in the 'High' group showed a greater lean mass (P<0.05), whereas women in the 'Low' group had higher triglycerides (P<0.05). In analyzing characteristics of lifestyle habits, it was found that the 'High' group showed significantly higher scores for 'vitality level (P<0.001)', 'self-rated health status (P<0.001)', 'regular medical checkups (P<0.05)', and 'regular exercise (P<0.05)'. The average score for dietary habits was significantly high in the 'High' group (P<0.05). Furthermore, ordinary dietary habits showed a significant positive correlation (P<0.001) with SPF in the regression analysis after adjusting for disturbance factors. From these results, ordinary desirable dietary habits were shown to be an important factors having positive effects SPF. Therefore, healthy dietary and lifestyle habits should be practiced to improve the SPF of middle-aged women. For this purpose, related educational programs should be developed for the middle-aged women to take interest in their dietary habits.

Purpose : This study was performed to investigate the level of obesity awareness and to help to prevent and to treat obesity by examining the relationship between knowledge of obesity and life style. Methods : Of the students who were surveyed, 1514 answered seriously and were accepted as subjects for the study. The questionaire was anonymous and was filled in by the students themselves. Body mass index was used to compare and analyze the subjects according to gender and age, with 85 percentiles or lower as group one, 86-94 percentiles as group two, and 95 percentiles or higher as group three. Results : Among the boys, level of obesity-awareness was significantly higher(P<0.01) in the obese group than in the normal-weight group. Among the girls, there was no difference in the level of obesity-awareness among the groups(P=0.332). The knowledge of obesity between the groups was not significantly different in either boys or girls. As for the relationship between healthy eating habits and knowledge of obesity, there were no significant differences in either boys or girls. There was no significant difference between the habit of regular exercise and the knowledge level of obesity in either boys or girls. Conclusion : Although this was a localized study and the students were aware of the seriousness of obesity to a certain extent, there was no difference in knowledge of obesity between normal-weight students and obese students. Also, there was no relationship between knowledge of obesity and healthy eating habits or the presence/absence of regular exercises.

Objectives: This study was carried out to evaluate the socio-demographic, style of living, and health related behaviors of community residents between urban and rural areas in Jeonbuk province. Methods: The data was obtained from 2,086 residents who lived in Jeonbuk province from July to September 2001 which included 1,238 residents in urban area and 848 residents in rural area. Results: The results were as follows; There were significant differences socio-demographic characteristics including occupation and educational level of the populations between urban and rural areas. In the urban populations, housewives, professional classes, and people who received collage graduate education were significantly higher, people who were engaged in the primary industries and lower educational classes(below middle school), in contrast, were significantly lower than in the rural populations. In the practice of health behavior, consumption of health foods and amount of exercise in urban populations were significantly higher than in the rural, whereas the state of health, prevalence of chronic disease, Body Mass Index(BMI), consumption of ethanol and cigarette, and hours of sleep were not significantly different between the urban and rural populations. In the eating habits, rate of surfeit, vaccination of hepatitis B, and screening of cancer in the urban populations were significantly higher than in the rural, rate of regular meal, taste of salted food, consumption of vegetables, in contrast. were significantly lower than in the rural. But, consumption of coffee, intake of meat, and periodic medical checkup were not significantly different between urban and rural communities. Logistic regression analysis revealed that the factors associated with subjective thought on health state were sex, age, occupation, educational level, exercise, and consumption of coffee. Logistic regression analysis to find related factor with prevalence of chronic disease was conducted. As a results, age, educational level, BMI, intake of meat, screening of cancer, and consumption of health foods were related to prevalence of chronic disease. Conclusions: The study showed that special attention to device the health plan are necessary and it suggested that consideration of regional differences are required to provide the community health projects.

Objectives : We aimed to explore the relationship among fatigue and perceived stress, depressive mood in the working population. We also examined associations with demographic and life style factors and investigated the effect of individual coping skills on these associations. Methods : Fatigue Severity Scale(FSS), Perceived Stress Scale(PSS), Brief Encounter Psychosocial Instrument - Korean version(BEPSI-K), Beck Depression Inventory(BDI), Stress Coping Skill Questionnaire were administered to 621 civil servants. All of above and other demographic factors are self-administered questionnaire survey and this study is cross sectional. Results : Mean FSS score was 3.04 which was lower than 3.22, the severity cut off score. FSS, PSS, BEPSI-K, BDI were all higher in female. Subjects with active coping skills showed relatively low fatigue, perceived stress, depressive mood than those with passive coping skills. Logistic regression analyses indicated that the PSS, BDI, BEPSI-K in working population increase the risk of fatigue and regular exercise lowers the risk. Conclusions : Adults who were afflicted by stress, experienced depressive mood or were physically inactive were at much higher risk of feeling fatigue. Since no other large data sets are available for fatigue, the results from this study could serve a very useful purpose, to furnish a basis for comparison with future research results based on more complete data.

Purpose : To evaluate the usefulness of the breathing exercise,we analyzed the change in the RPM signal and the diaphragm imagebefore 4D respiratory gated radiation therapy planning of lung cancer patients. Materials and Methods : The breathing training was enforced on 11 patients getting the 4D respiratory gated radiation therapy from April, 2016 until August. At the same time, RPM signal and diaphragm image was obtained respiration training total three steps in step 1 signal acquisition of free-breathing state, 2 steps respiratory signal acquisition through the guide of the respiratory signal, 3 steps, won the regular respiration signal to the description and repeat training. And then, acquired the minimum value, maximum value, average value, and a standard deviation of the inspiration and expiration in RPM signal and diaphragm image in each steps. Were normalized by the value of the step 1, to convert the 2,3 steps to the other distribution ratio (%), by evaluating the change in the interior of the respiratory motion of the patient, it was evaluated breathing exercise usefulness of each patient. Results : The mean value and the standard deviation of each step were obtained with the procedure 1 of the RPM signal and the diaphragm amplitude as a 100% reference. In the RPM signal, the amplitudes and standard deviations of four patients (36.4%, eleven) decreased by 18.1%, 27.6% on average in 3 steps, and 2 patients (18.2%, 11 people) had standard deviation, It decreased by an average of 36.5%. Meanwhile, the other four patients (36.4%, eleven) decreased by an average of only amplitude 13.1%. In Step 3, the amplitude of the diaphragm image decreased by 30% on average of 9 patients (81.8%, 11 people), and the average of 2 patients (18.2%, 11 people) increased by 7.3%. However, the amplitudes of RPM signals and diaphragm image in 3steps were reduced by 52.6% and 42.1% on average from all patients, respectively, compared to the 2 steps. Relationship between RPM signal and diaphragm image amplitude difference was consistent with patterns of movement 1, 2 and 3steps, respectively, except for No. 2 No. 10 patients. Conclusion : It is possible to induce an optimized respiratory cycle when respiratory training is done. By conducting respiratory training before treatment, it was possible to expect the effect of predicting the movement of the lung which could control the patient's respiration. Ultimately, it can be said that breathing exercises are useful because it is possible to minimize the systematic error of radiotherapy, expect more accurate treatment. In this study, it is limited to research analyzed based on data on respiratory training before treatment, and it will be necessary to verify with the actual CT plan and the data acquired during treatment in the future.
