The study was conducted to analyze the impacts of COVID-19 on the number of dental trauma patients. Based on the data provided by the Health Insurance Review and Assessment Service's Healthcare Bigdata Hub, dental trauma which occurred from 2010 to 2020 was analyzed. Since the outbreak of COVID-19, the incidence of dental trauma per 100,000 decreased compared to the average Incidence between 2017 to 2019. By age, it decreased by 5.4% (p = 0.017) for 0 - 4 years old, 30.3% (p < 0.001) for 5 - 9 years old, 39.5% (p < 0.001) for 10 - 14 years old, 14.5% (p = 0.002) for 15 - 19 years old, 1.3% for 20 - 29 years old, 0.2% for 40 - 49 years old, 2.7% for 50 - 59 years old, 1.2% for 60 years old or older, but it increased by 2.5% for 30 - 39 years old. Compared monthly, before and after the outbreak of COVID-19 confirmed patients, the number of dental trauma patients dropped sharply. After the outbreak of COVID-19, the incidence of dental trauma decreased significantly for under 20 years old, but the decrease was not significant for 20 years old or older.

This study was performed to assess diet qualities by sexes and ages of adults over thirty years old in Jeon-ju area. Diet survey with one day 24-recall method was used done for 382 subjects(129 males & 253 females). Survey sample was divided into six groups by sex and age groups: male 30-49, male 50-64, male 50-64, male 65-79, female 30-49, female 50-64 and female 65-79 years. Diet quality was assessed by NAR(Nutrient Adequacy Ratio), MAR(Mean Adequacy Ratio), INQ(Index of nutrition quality), KDDS(Koreans Dietary Diversity Score), Meal Balance, DVS(Dietary Variety Score), DQI(Diet Quality Index). The 5-point DQI assessed the important dietary guidelines for Koreans. The averages of energy, protein, P, vitamin B$_1$, vitamin B$_2$, niacin and vitamin C intakes were higher than 70% of RDA. The averages intakes of Ca and vitamin A were very lower than RDA all groups. The averages of MAR were 0.78, 0.81, 0.83 in male 30-49, 50-64, 64-79 years, 0.73, 0.77, 0.71 and in female 30-49, 50-64, 65-79 years, respectively. The averages of MAR in female 30-49 years and female 65-79 years were significantly lower than the averages MAR of male 65-79 years. The averages of Sugars and Beverages intakes were significantly higher in male 30-49 years than others. Animal food intake ratio(% total food intake) in the male 65-79 years(16%) was significantly higher than male 30-49 years(11%). The averages of Nutrition intakes were higher in male compared to female. The subjects who consumed all of the major five food groups were 5% in male 30-49, 17.8% in male 50-64, 25.0% in male 65-79 years, 18.9% in female 30-49, 23.7% in female 50-64, 11.5% in female 65-79 years. The averages of KDDS were 3.5, 3.9, 3.9, 3.8, 3.8, 3.5, respectively. The averages of Meal Balance were 8.6, 9.1, 9.1, 8.3, 8.4, 7.8, respectively. The averages of DVS 20.1, 19.9, 19.9, 20.5, 19.0, 17.2, respectively. The averages of DQI were 1.7, 2.2, 2.1, 2.0, 2.1, 1.7, respectively. 81.8% of the subjects had KDDS scores of 2 to 4 and 87.3% of the subjects has Meal Balance scores 4 to 10. In contrast, 89.8% of the subjects had DQI scores of 0 to 3. In view of these facts there are few who observed the five dietary guidelines for Koreans. There findings suggest that dietary qualities were associated with nutrient intake the relation factors may vary by sex and age of adults over thirty years old in Jeon-ju area. Common problems were lack of Ca, vitamin A and dairy products intakes. Therefore adults over thirty years old in Jeon-ju area need the important nutrient management such as Ca, vitamin A.

Age specific characteristics in Korean diet and their changes were analyzed with the demand model including the number of family members by age group as independent vasiables Urban household budget data, 773 household data in 1977 and 947 household data in 1983, was applied to the demand model. A series of F-test was carried out to set up the age groups by food item. The main results can be summarized as follows; 1. Food consumption patterns are remarkably different between 0-13 years old age generation and over 40 years old generation. The 0-13 years old generation reveals higher preference for milk, wheat product, fruit and milk and lower preference for rice and vegetable than any other age generation. This characteristics of the childhood diet has been formed In the generation born after 1970's and thus will be reserved as their generational characteristics. On the other hand, over 40 years old age group prefers rice and fish to fruit, milk and wheat product. Therefore we can conclude that over 40 years old age group maintains the traditional Korean diet pattern. 2. The preference for fish is low. in 20-30 years old age group than in any other age group and wheat product is Preferred highest in 6-13 years old age group of all age groups. Meanwhile the most remarkable change In food consumption pattern is shown in meats and vegetables. Namely in 30 40 years old age group the preference for meat has increased substantially and that vegetable has decreased to a great extent. 3. The declining per capita consumption of rice spreads like a wave to higher age. groups, but over 40 years old age group bas played an important role in reducing the decreasing rate of rice consumption. In order to restrain the declining rice consumption a special integrated food policy is required to induce rice consumption in less 30 years old generation.

The prevalence of hepatitis A virus (HAV) in a certain community reflects that community's living standard and hygienic condition. The seroprevalence rate of IgG anti-HAV has been changing with regions and times. In this study, we aimed to study the difference of seroprevalence of IgG anti-HAV according to sex, age and type of drinking water, and to know the vaccination rate and seroconversion rate for vaccinated subjects in Busan. A total of 644 samples were analyzed. The overall seroprevalence rate of IgG anti-HAV was 35.4% (228/644). There was no significant difference in sex (male 39.8%, female 32.7) (p>0.05). According to age, seroprevalence rate of anti-HAV were 55.0% in subjects aged 5~9 years old, 47.8% in 10~14 years old, decreced to 10.6% in 15~19 years old, 1.0% in 20~24 years old, 0.0% in 25~29 years old and increced with advacing ages ; 14.7% in 30~34 years old, 39.4% in 35~39 years old, 67.3% in 40~44 years old, 94.1% in 45~49 years old, 100.0% over 50 years (p<0.001). The seroprevalence of IgG anti-HAV was no statistical difference according to the types of drinking water (p>0.05). The vaccinated subject was 42 case only in below 25 years old. The seroconversion rate after vaccination was 88.1%.

For the purpose of estimating the status of physical growth of primary school students in Busan area, the author had performed an investigation and analysis on the physical integrated value for past 6 years of random sampled 656 students (male 374, female 282). The summarized results were as follows : 1. The most rapid growth age of body-height was 7-8 years old as 5.9 cm in male and 10-11 years old in female as 6.5 cm, and the growth curve of body-height was crossed at 10-11 years old. 2. The most rapid growth age of body-weight was 9-10 years old as 3.1 kg in male and 10-11 years old in female as 3.9 kg, and the growth curve of body-weight was crossed at 10-11 years old. 3. The most rapid growth age of chest-girth was 8-9 years old as 3.1 cm in male and 9-10 years old in female as 2.9 cm, and the growth curve of chest-girth was not corssed. 4. The most rapid growth age of sitting-height was 6-7 years old in both sex as 3.3 cm and 3.4 cm, and the growth curve of sitting-height was crossed at 8-9 years old. 5. Using the physical integrated value was much simple and desirable at comparing with the areas. And the physical integrated value of primary school students on Busan area compared to Korean standard physical status was relatively good as body-height +0.33, +0.30, body-weight +0.33,+0.35, chest-girth +0.65, +0.57 and sitting-height +0.10, +0.20 with each sex.
