This study was conducted to investigate the relationships among body composition, dietary intake, and clinical blood indices in college students by body mass index (BMI). Their body compositions were determined by means of BIA (Bioelectrical Impedance Analysis) method. Their dietary intake was determined using a 3-day record method and their hematological indices were determined by semi-automated microcell counter (Sysmex F-520). Their serum lipid levels were measured using biochemical analyzer (Spotchem). Subjects were classified as underweight, normal or over-weight groups according to their BMI. The subjects were 69 healthy college students aged 20 to 26 years. The average age, height, weight, and BMI was 21.3 years, 162.6 cm, 54.4 kg, and $20.6cm/m^2$, respectively. Their average consumption of energy was 1693 kcal, 84.7% of RDA and their mean ratio of carbohydrate: protein: fat were 54.5 : 16.4 : 29.0. There was no significant difference in nutrient intake among the groups except ${\beta}$-carotene and vitamin C. The ${\beta}$-carotene intake was significantly higher in the underweight group. Vitamin C intake was significantly higher in the overweight group. The mean intakes of Ca, Fe, Zn and folate of subjects were 74.8% to 83.2% of RDA. Especially, intakes of Ca, Fe, Zn and folate were lower in the abnormal weight groups. The overall mean values of the hematological indices in female college students were within the normal range and there was no significant difference among the groups. However, anemic subjects with hemoglobin (< 12 g/dl) and hematocrit (< 36 g/dl) accounted for about 11% of the subjects. The everall mean values of the serum lipid levels were within the normal range and there was no significant difference among the groups. But serum HDL-cholesterol level of the overweight group was lower than that of the other groups. LDL-/HDL-cholesterol ratio and AI index were significantly higher in the overweight group compared to the other groups. Based upon this study, it is necessary for college women to be educated regarding consuming more Ca, Fe, Zn, folate and less fat and cholesterol in order to have better health promotion.

This study examined the relationship between the serum GGT (gamma-glutamyl transferase) and uric acid level in obese male adults. A total of 14,283 adult males aged 20 years or more, who visited the health examination center of Gyeonggi Regional General Hospital from January 2017 to August 2018 and underwent a physical examination, were enrolled in this study. The obesity criteria were defined by the Asia-Pacific regional standards. Abdominal obesity was defined as a male waist circumference of more than 90 cm. An increase in the serum uric acid and serum CGT levels of the male subjects was defined as 7.0 mg/dL or more and 56 IU/L or more, respectively. The results showed that the serum GGT and uric acid levels were higher in the overweight and obese groups than in the normal weight group. In the obese group, the serum GGT and uric acid were significantly higher in the patients with abdominal obesity. On the other hand, there was no difference compared to the low body weight group. The overweight and obesity groups showed a higher risk of elevated serum GGT and hyperuricemia than the normal weight group, but a low body weight did not affect the serum GGT elevation and hyperuricemia. Overall, the serum GGT and uric acid levels are useful for evaluating overweight and obesity in adult males.

A dietary survey of 100 children, aged 5 to 6, of Y.C. Kindergarten located in Yowido apartment compound of Seoul, was conducted July 18 to August 21, 1979. The results are summarized as follows: General family environment: Ninety four percent of the subjects were from families having two to three children, without grandparents in the home. One hundred percent of fathers were educated at or above the college level, while 83.9% of mothers had completed college. Mothers' ages ranged from 30 to 40 years, with 58% in the $31{\sim}35$ age bracket. Nearly 60% of the fathers were office and government employees, 10% were professors and teachers, 30% were engaged in businesses and other work, while 91.3% of mothers were unemployed. Anthropometric measurements: Mean values of standing height, body weight, girth of head and girth of chest, ranged from the 75th to the 90th percentile of Korean standards. None of the subjects had anthropometric indicators below the 5th percentile, representing the malnutrition borderline, of the Korean standards; while 12%, 24%, 17% and 14% of subjects supposed the 97th percentile in standing height, body weight, girth of head, and girth of chest, respectively. Furthermore, 58% of subjects exceeded Jelliffe's standard in arm circumferences; 60%, in triceps skinfold thickness; and 14.5% of subjects exceeded 120% of the latter standard. From this data, a certain number of these children were judged to he rather overweight. Dietary intake: Mean intake per day of energy and of nutrients, excluding iron, reached or exceeded Korean recommended dietary allowances. The energy input ratio of carbohydrate: protein: fat was 61.4 : 13.2 : 25.4, showing lower dependance on carbohydrates and higher dependance on fat for energy needs, compared with the average for Korean children of the same age group. Mean FAO-protein score of each subject's diet was shown to be as high as 90.6. Energy intake was divided among breakfast, lunch, and evening meal, on the average, in a ratio of 19.6 : 24.1 : 23.0. Approximately 33.3% of the daily caloric intake came from the snacks. Nutrition Knowledge of mothers: Nutrition knowledge of mothers was highly scored. Mothers' self-evaluations of their knowledge of nutrition was highly correlated with attitudes toward nutrition behavior.

Attention-deficit/Hyperactivity disorder(ADHD) is the most common psychiatric disorder of childhood and among the most prevalent chronic health conditions affecting school-aged children. Children with ADHD experience significant functional problems, such as school difficulties, academic underachievement, troublesome interpersonal relationships with family members and peers, and low self-esteem. The most widely used pharmacological treatments for ADHD are psychostimulants, such as methylphenidate and amphetamine salts. These medications provide clinical efficacy by increasing the availability of catecholamines, primarily dopamine, in the frontal lobe of the brain. immediate-release(IR) formulations of sychostimulants were among the most effective psychotrophic medications in the psychopharmacological treatment. However, there are some limitations of IR formulations：the short half-life and duration of efficacy, which result in the need for multiple daily dosing and the poor compliance. These limitations have led to the development of once-daily, extended-release(ER) formulations of methylphenidate and amphetamine salts. However, these ER formulations may not be as immediately helpful to ADHD children due to delayed onset of action and the acute tolerance which is the failure to sustain the efficacy with the same concentration of drug as the initial stage of medication. OROS-methylphenidate(Concerta$^{\circledR}$) given once a day produces an ascending-pattern plasma drug level generated by the osmotically released, timed drug-delivery system. These new formulations of the psychostimulants have been shown to be a useful alternative to old stimulant medications through the evidence by the clinical trials.

The purpose of this study was to investigate the effects of combined exercise on blood inflammatory factors, DHEA-s and arterial stiffness in elderly women. The subjects were 42 elderly females volunteers, aged 70 to 85 years, composed of the combined exercise group (n=21) and control group (n=21). The 60 minute combined exercise program(aquarobics 1 time/week, strength exercise 2 times/week) was performed 3 times per week for 12 weeks, and the intensity was progressively increased every 4 weeks(1-4 weeks: RPE 12 to 13, 5-8 weeks: RPE 13 to 14, 9-12weeks: RPE 14 to 15). The test data were analyzed by two-way repeated measures ANOVA, paired t-test, independent t-test and the alpha level of .05 was set for all tests of significance. As a result, the combined exercise for 12 weeks reduced the inflammatory response of elderly women, and DHEA-s was found to have a positive effect on aging hormone. The arterial stiffness decreased the central arterial blood pressure (systolic and diastolic), prevented the increase of the pulse pressure and the wave increase index, and decreased the pulse wave velocity. These results suggest that regular and continuous combined exercise may be recommended for the healthy aging and longevity of elderly women by inducing anti-inflammation effect and improving the aging hormonal function and the vascular health.

This is a longitudinal study of drinking older adults aged 65 and older to determine how their social activities and alcohol consumption change over time, and how social activities affect alcohol consumption among drinking older adults. The main findings are as follows First, we found a decrease in social activity and alcohol consumption among the elderly over time, but this was not statistically significant. However, individual differences in the rate of change in social activity and alcohol consumption were found, and the specific factors of these individual differences were examined in the conditional model. The results of the conditional model showed that, for social activity, the higher the initial level of social activity, the older the age, and the lower the initial amount of alcohol consumed by men than women. Next, for the amount of alcohol consumed, the better the health status, the more the amount of alcohol consumed decreased significantly for male elderly than female elderly, smokers than non-smokers, and elderly with and without disabilities. Based on the results of the above analysis, suggestions were made to promote social activities and reduce drinking among the drinking elderly in Korea.

This study examined the contribution of the risk factors that cause cardiovascular disease in Koreans. The subjects were 20,012 adults aged 30~74 years who were enrolled from the 2005~2013 Korean National Health and Nutrition Examination Survey, had filled the risk factors data, and had no cardiovascular disease history. Data analysis was conducted using SAS 9.3, and a weighted composite sample design analysis was performed. The contribution was obtained by applying a squared semi-partial correlation. As a result, they were higher in the order of age (63.9%), smoking (17.3%), systolic blood pressure (7.9%), diabetes (6.9%), antihypertensive medication use (3.0%), and BMI (0.9%) in men. In women, the contributions were in the order of age (54.1%), systolic blood pressure (23.5%), diabetes (13.6%), antihypertensive medication use (5.1%), smoking (3.1%), and BMI (0.6%%). According to age bracket analysis, smoking (51.8~33.7%) was the biggest risk factor, followed in order by age (26.6%) in their 30s and systolic blood pressure (17.3~21.0%) in those older than 40 years in men. In women, the systolic blood pressure (56.2~40.5%) was the main contributor to the risk factors, followed by age (24.0%) in their 30s and diabetes (13.6~32.6%) in those older than 40 years. The contribution of the income level was similar. Therefore, to prevent cardiovascular disease, various programs that reflect the contributions of the risk factors should be developed. Moreover, it is recommended to use the results shown in this study as basic data.

Our country is defenseless against the aging population in society that is suddenly and rapidly increasing. This is expressed as the aging shock and aged society earthquake, warning us of the crisis in the future society. Senior citizens of Korea are a group that does not receive proper education due to various social factors, and it is a group that requires lifelong education more than any other group, and therefore, senior citizens have become a priority target for lifelong education. Thus, the need for lifelong education for seniors can be said to be in establishing a new senior citizen image so that they may live a fuller retirement by improving their abilities to appropriately adapt to the rapidly changing modern society due to the digital times. Furthermore, with the enhanced cultural level and personal desire for a fuller life in the modern society, the necessity for leisure activities has been emphasized. Instead of simply relieving stress through leisure activities, it aims at being provided with educational opportunities through leisure activities. Therefore, senior leisure activity education should be an important method for establishing the senior citizen identity of a self-oriented senior, productive senior, volunteering senior, informed senior, and a well-rounded senior, which are all the image of senior citizens in the 21st century. In addition, a specialized leisure activity program that systematically provides education for leisure activities should be performed from the perspective of lifelong education. Hence, the significance of senior citizen leisure activities as lifelong education is in improving health, enhancing sociability and realizing one's self, while improving the quality of life for senior citizens. It will be greatly meaningful for establishing the new senior citizen image in which they independently live their own lives, while not being dependent on others, as required in the 21st century.

The study aimed to investigate the effects of differences between personal income and social deprivation on the association between cardio-cerebrovascular disease (hypertension, stroke) and periodontal disease. This study used 12 years of cohort data from the Korea National Health Insurance Service covering the years 2002 to 2013. Among the patients aged more than 40 years who had received treatment for periodontal disease 224,067 and 284,730 who had not received treatment for hypertension and stroke, respectively, were included in the analysis. The Kaplan-Meier analysis revealed differences in the rate of treatment for cardio-cerebrovascular disease (hypertension, stroke) according to regional differences, the rate of treatment increased as the composite deprivation index value increased. The difference in treatment rates for cardio-cerebrovascular disease (hypertension, stroke) according to income was found to be higher in the treatment group with low income. This study empirically proved that the association between systemic disease and periodontal disease varies depending on personal income and the regional socioeconomic deprivation level. This shows that the clinical influence of periodontal illness on systemic disease differs according to the personal socio-demographic characteristic and residential area and that an individual's characteristic (income and the regional) needs to be considered along with the patient's clinical intervention in the disease treatment process.
