This study was based on the data of total mineral content of about 99% at the age of 16-26 years, we aimed at female university students who are important for bone formation in their early 20s. The purpose of this study was to investigate factors of eating habits affecting their bone density and to provide data to prevent osteoporosis which might occur in the future. It was conducted on 100 female university students in their 20s, the bone mineral density according to BMI was measured by DEAX, and the analysis of 10 eating habits items and the results of BMD measurement on their own results in Excel 2010. As a result, the height was $161.08{\pm}4.70cm$, the weight was $52.43{\pm}6.43kg$, and the BMI was $20.22{\pm}2.48$, which correlated with BMD (p<0.05). According to the BMI classification, 20 had low weight and 80 had normal weight, and BMD was $0.20{\pm}0.41$ at normal weight. In the same sex, the mean T-score of the young adult group was $-0.04{\pm}0.99$ compared with the BMD of the young adult group, and the mean Z-score of the same age group was $0.02{\pm}0.93$ (p<0.001). Eating habits affecting bone mineral density were significantly affected by 3 meals per day, 1-3 cups of coffee per day and p<0.05 for Low salt formula intake. 6-9 dairy product intake was also p<0.05 but not significant. Therefore, it is considered that when 20s female students become middle-aged woman, they should have proper eating habits so that osteogenesis can be improved at young age in order to prevent bone disease.

Aiming at the total 200 pregnant women including 150 ones registered with the Health Center of Chung Ku District and 50 ones registered with the Health Center of Mapo District, we have conducted a research study of the socio-medical characteristics, maternal child health, and the status of nutritional intake which has utilized the application of convenient method for the study of nutritional status, during the period of April 20 to May 25, 1983. And we have obtained the following conclusions: 1. Regarding age distribution, the pregnant women aged from 26 to 30 were most numerous, which was 54.0%. The percentage of women who experienced the first pregnancy was 12.0% and the percentage of those who experienced the second pregnancy was 37.0%, which was the highest. Regarding the weeks of pregnancy of the pregnant women, the first trimesterr was 11.5%, the second trimester 30.0%, and the third trimester 58.6%. 2. Regarding academic achievements, the pregnant women who graduated from middle schools reached 43.5%, which was the highest percentage. Regarding economic status, the pregnant women who owned their own houses were only 21.0%. And the pregnant women whose monthly income was from 300,000 won to 400,000 won were 40%, which was the most numerous. 5. The women above 15 years old who experienced the first menstruation were 84.0%. And those who experienced abortion were totally 54.4%. and 35.5% among those women experienced artificial abortion. 4. 70.5% of the pregnant women said that their health condition was excellent, 24.5% felt subjective complaints, and 5.0% specially received medical consultation for their diseases. 5. 82.0% received prenatal care, but 60.5% regularly received prenatal care. 68.0% received the education for nutrition and only 19.5% regularly received the education for nutrition. 6. Regarding the family composition, the families consisting of two generations were 47.0%, which was the most numerous. 97.5% of the preparation for meals was conducted by housewives. They said that they did not lack time for meal preparation. 7. 94.9% of the pregnant women said that they had eaten as in ordinary times during their pregnancy. 25.5% said that there were tabooed foods. Tabooed foods are chiefly pork, chicken, milk, and eggs. 68.0% don't drink milk during pregnancy, 32.5% take the intake of vitamins, and 20.5% take iron supplement. 8. The average amounts of the intake of protein, fat, and carbohydrate of a pregnant women are 49.3gm, 29.4gm, and 205.1gm respectively, which showed the phenomenon in which the amount of the intake of nutrition increased as the weeks of pregnancy increased. The average amount of the intake of salt was 14.2gm. 9. Regarding the hemoglobin value of all pregnant women, those whose hemoglobin value was less than 11.0gm were 66.5%, those whose hemoglobin value was 11 to 12 gm were 16.5%. and those whose hemoglobin value was above 12gm were 17.0%. The pregnant women whose hemoglobin value was less than 11.0gm in the first trimester of pregnancy, in the second trimester, and in the trimester were 81.8%, 62.8%, and 64.9% respectively. This shows that the phenomenon of anemia increased as the weeks of pregnancy increased 10. Regarding physical development of a pregnant woman during prenatal period, the height and weight were $156.7cm{\pm}14.1$ and $51.1kg{\pm}58$ respectively. When the standard increase of a prenatal weigt gain is set as 100%, the women over the range of 100% were 28.0% and the women under the range of 80% were 37.0%.

This study is to look at the risk of chronic diseases in adults and oral health behaviors affecting periodontitis by gender. This study selected 3,071 males aged 35 to 65, 4,273 females, and 7,344 people as the final subjects of the study using the sixth original data from the National Health and Nutrition Survey. In this study, subjective oral health classified under 'bad' presented 1.69 times(p<0.001) the risk of Periodontitis for males and 1.50 times(p<0.001) for females. There was a 2.01 times(p<0.001) of a risk of periodontitis for male and 1.40 times(p=0.001) of a risk for females. Smokers have a 1.68 times(p<0.001) of a risk for males and 2.07 times(p<0.001) of a risk for females, thus a higher risk for periodontitis for females. The risk of periodontitis was 1.44 times(p<0.001) of a risk for males and 1.30 times(p<0.05) for females when compared in normal hypertension. Obesity was at a rate of 1.199 times(p<0.05) as much for males in the non-military group, 1.202 times(p<0.05) that of females for periodontitis and putting females slightly more at risk. For diabetes, males were at risk of 1.28(p<0.05) whereas it being 1.53 times(p<0.05) for females, compared the average health female. In total, Males were found to be at the greatest risk of periodontitis, while women were at the highest risk for smoking. All parameters except smoking and diabetes show a higher risk of periodontitis for females. As males are more likely to have a higher risk of periodontitis than females, they are considered to be more interested in oral health care and need systematic oral health education and policies to prevent oral diseases.

Objective : The purpose of this study is to analyze the charcateristics of inpatients in Ophthalmology, Otolaryngology & Dermatology Clinic by gender, age, season, and department of medical care after hospitalization from March, 2012 to February, 2018. Method : From March 1, 2012 to February 28, 2018, patients who were admitted to the Ophthalmology, Otolaryngology & Dermatology Clinic of Korean Medical Hospital were classified by gender, age, department, and season, and their relationship, hospitalization period, number of outpatient visits Differences were analyzed objectively using various statistical methods using IBM SPSS 18.0. Results : 1. The number of inpatients was 432, including duplication. Of these, 317 were female and 115 were male. The number of female patients was 2.8 times higher. 2. The average age of the inpatients was 43.9 years and the number of middle-aged 40-50 patients was 48.6%. 3. The number of inpatients in the departments was in the order of dermatology, otology, laryngology, rhinology, and ophthalmology. The most hospitalized diseases were eczema in the dermatology department, sudden hearing loss in the otology department, tonsillitis/peritonsillar abscess, rhinitis in the rhinology department, and dry eye syndrome in ophthalmology. 1) The effect of gender on the difference in the number of inpatients by subdivision was statistically significant. 2) The effect of age on the difference in the number of inpatients by subdivision was statistically significant. 3) The effect of seasons on the difference in the number of inpatients was not statistically significant. 4. The number of inpatients by season was in the order of winter, spring, summer, autumn, and the number of inpatients decreased significantly in autumn. 1) The effect of gender on the difference in the number of hospitalized patients by season was not statistically significant. 2) The effect of age on the difference in the number of hospitalized patients by season was not statistically significant. 5. The average length of hospital stay for inpatients was 10.7 days. 1) The effect of gender on length of hospital stay was not statistically significant. 2) The effect of age on hospital stay was not statistically significant. 3) The effect of the subdivision on hospital stay was statistically significant. 4) The effect of the season on hospital stay was not statistically significant. Conclusion : As a result of this study, the most distinctive feature of the present study was the high rate of inpatients with otic disease like idiopathic hearing loss and Meniere 's syndrome and the high rate of female patients. This may be related to the increased prevalence of the disease and the severity of the disease. In addition, the high rate of female patients suggests that women are more likely to be affected by illnesses, as well as to have more medical use and severe symptoms requiring hospitalization. In the future, it would be better to provide various treatment plans and policies for patients with otic diseases and female patients. Also it would be good if studies on these fields are made in the future.

This study aims to shed light on the cultural history of Hajodae(河趙臺) enjoyed by writers of the Joseon Dynasty by analyzing the origin and the contents of the landscape based on the literature materials of Hajodae in Yangyang(襄陽). The results of the study are as follows. First, Hajodae is a space that is said to have been visited by Ha Ryun(河崙) and Jo Jun(趙浚). However, since this story has not been confirmed in the literature, various opinions coexisted in history. Jo Wi-Han(趙緯韓) quoted the opinions of aged people who lived in Yangyang, saying that it could be Jo In-Byeok(趙仁壁), not Jo Jun(趙浚), and Jo Deok-Rin(趙德鄰) recorded it as "遐眺臺", which means "a stand for a distance view." There is a need to clearly present the origin of Hajodae by revealing the literary authority. Second, Hajodae was talked about as the best scenic site in Gwandong(關東) in the middle of the Joseon Dynasty. during the mid-Joseon Dynasty. The writers of the time mentioned Hajodae as one of the best scenic sites in Gwandong, which soon became a symbol of Yangyang. These records of Hajodae show a relatively decreasing trend entering the late Joseon Dynasty. It is believed to be the result of the slight degrading in the status of Hajodae as the Eight Views of Gwandong were established and Naksansa Temple(洛山寺) gained fame. Third, the writers of Joseon enjoyed the scenic sites through various landscapes of Hajodae. The open terrain on three sides allowed a sea view and provided an opportunity to develop a great spirit or to reflect on oneself. On the other hand, the strange rock formations and cliffs, which correspond to a close-up view, drew the attention of tourists, and the Rosa rugosa Thunb. blooming in the Hajodae area was enough to show a bizarre charm. This shows the various charms of Hajodae, suggesting that the management of such landscape is necessary. Fourth, a Chinese poem about Hajodae shows the spatial meaning of Hajodae. Looking into all sides of the Chinese poem about Hajodae, a case of unburdening one's mind on the landscape, and the aspect a person compared oneself to the natural landscape or projected one's consciousness onto it, and a case of recalling Ha Ryun and Jo Jun, illustrious retainers in the early Joseon Dynasty are confirmed. It can be seen that it results in the aspect of expressing one's impressions and looking back on history through the landscape.

Purpose: To investigate the effect of a mother's modeling and feeding practices on the eating behavior of the children. Methods: From April to June 2018, 1,036 young children aged 2 to 6 years and their mothers in Gyeongsan, Gyeongsangbuk-do, were examined for their eating behavior and feeding practices using a verified dietary behavior test (DBT). The children's dietary behavior was classified into four categories: "access evasiveness", "sensory acuity", "hyperactivity", and "irregularity". The mother's eating behavior was classified into three categories: "pickiness", "negligence", and "irregularity", and feeding practice types were classified into two categories: "responsibility/monitoring", and "restriction/pressure". The differences between the groups were tested using the t-test, ANOVA, and Duncan's multiple range test. The influence of feeding practices on the children's eating behavior was analyzed by hierarchical regression analysis while controlling for the mother's modeling. Results: The problem rates of irregularity, negligence and pickiness in the mother's modeling were 33.7%, 22.8%, and 20.7%, respectively. An analysis of the mother's feeding practices revealed that responsibility/monitoring had a middle, high and low significance in 74.2%, 17.3%, and 8.5% of respondents, respectively and the risk rate of restriction/pressure when guiding children to eat was 15.3%. The problem rates for sensory acuity, access evasiveness, irregularity, and hyperactivity in children were 27.9%, 26.1%, 24.8%, and 22.0%, respectively. Among the four eating behavior characteristics of children, the child's access evasiveness and sensory acuity were more affected by their pickiness rather than the mother's feeding practices, and the child's hyperactivity was more influenced by feeding practices than the mother's eating behavior. The child's irregularity was similarly affected by the mother's eating behavior and feeding practices. Conclusion: Since the mother's eating behavior and feeding practices affect the children's eating behavior, a diet improvement program for children should consider not only the nutrition education of children but also the mother's eating behavior and provide the necessary intervention for feeding practices.

Purpose: Adult Korean men belonging to the main economically active population are known to have long sedentary hours. This study was undertaken to determine the difference and relevance of sedentary hours on the nutrition, diet, and health status of adult men, and to suggest how to prevent health risk factors. Methods: Subjects (n = 1,068) were classified into 4 groups based on their sedentary hours, ranging from the first quartile (Q1) having the least hours spent sitting, to the fourth quartile (Q4) spending the longest hours. Results: Subjects belonging to Q4 had the lowest average age, the largest waist circumference, and the highest level of education. Among those engaged in economic activities, the ratio of white-collar workers was significantly higher in Q4. Accordingly, the rate of not doing high-intensity or moderate-intensity physical activity while working was also the highest in Q4. A significant difference was obtained in the drinking frequency between groups, but this was found to be associated with the average working hours rather than sedentary hours. The proportion of not doing aerobic exercise was higher with longer sitting hours. The highest diagnosis of diabetes (8.8%) was obtained in the Q4 group. Among the factors related to cardiovascular disease, only low density lipoprotein-cholesterol showed a significant difference, with Q4 being significantly higher than Q1. Considering energy and nutrient intake, vitamin B₁ and calcium intake were the lowest in the group with the longest sitting hours, as well as the least consumption of vitamin C than the recommended estimated average requirement. Conclusion: The results of this study suggest that the health and nutritional status of Korean adult men are affected by sedentary hours. This should be recognized as a health risk factor and guidelines need to be developed for sedentary lifestyle management.

Purpose: This study determined the relationships between maternal comprehensive feeding practices (CFP) and dietary practices of preschool children. Methods: Participants of the study were 227 mothers of children aged 3 to 5 years attending daycare centers and kindergartens in Seoul and Gyeonggi Province of Korea. The Comprehensive Feeding Practices Questionnaire was used to assess the maternal feeding practices. The Nutrition Quotient for Preschoolers (NQ-P) was measured to evaluate dietary practice and diet quality of children. Results: The balance of NQ-P for children was positively correlated with the modeling, restrictions for weight control, encouragement of balance and variety, pressure, and involvement among maternal CFP. Moderation of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement among maternal CFP. However, it was negatively correlated with emotion regulation, food as a reward, and child control in maternal CFP. Among maternal CFP, the environment of NQ-P was positively correlated with monitoring, modeling, teaching about nutrition, encouragement of balance and variety, environment, and involvement, and it was negatively correlated with emotion regulation. As a multiple regression analysis, maternal CFP that positively predicted balance of NQ-P indices were restricted for weight control, pressure, and involvement. Among maternal CFP, encouragement of balance and variety, and environment were positive predictors, while food as a reward, and child control were negative predictors for the moderation of NQ-P. Items of maternal CFP positively predicting environmental factors of NQ-P were monitoring and environment. Conclusion: Mothers are recommended to practice dietary guidance to their children, such as monitoring, modeling, teaching about nutritional information, recommendation of balance and diversity, healthy eating environment, and participation in meal plan and preparation, while they are advised not to conduct any adverse dietary guidance such as emotional control, compensation with food, child control, and food coercion.

Purpose: Since the coronavirus disease 2019 (COVID-19) pandemic began, new variants of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have emerged, and distinct epidemic waves of COVID-19 have occurred for an extended period. This study aimed to analyze the clinical and epidemiological characteristics of children with COVID-19 from the third wave to the middle of the fourth epidemic wave in Korea. Methods: We retrospectively reviewed the medical records of hospitalized patients aged ≤18 years with laboratory-confirmed COVID-19. The study periods were divided into the third wave (from November 13, 2020 to July 6, 2021) and the fourth wave (from July 7 to October 31, 2021). Results: Ninety-three patients were included in the analysis (33 in the third and 60 in the fourth waves). Compared with the third wave, the median age of patients was significantly older during the fourth wave (6.7 vs. 2.8 years, P=0.014). Household contacts was reported in 60.2% of total patients, similar in both periods (69.7 vs. 55.0%, P=0.190). Eighty-one (87.1%) had symptomatic SARS-CoV-2 infection. Among these, 10 (12.3%) had no respiratory symptoms. Anosmia or ageusia were more commonly observed in the fourth epidemic wave (10.7 vs. 34.0%, P=0.032). Most respiratory illness were upper respiratory tract infections (94.4%, 67/71), 4 had pneumonia. The median cycle threshold values (detection threshold, 40) for RNA-dependent RNA polymerase (RdRp) and envelope (E) genes of SARS-CoV-2 were 21.3 and 19.3, respectively. There was no significant difference in viral load during 2 epidemic waves. Conclusions: There were different characteristics during the two epidemic waves of COVID-19.
