Objectives: The aim of this study was to examine the association between current suicidal or violent behavior and deficits of specific neurocognitive variables in child and adolescent inpatient samples diagnosed with mood disorder. Methods: A retrospective review of the charts of mood disorder patients hospitalized at Samsung Medical Center between April 2004 and April 2015 was conducted. Child and adolescent patients aged between 10 and 18 years old and those who finished neurocognitive function testing during their hospitalization were included. Among them patients whose full scale IQ was between 85 and 115 were selected (N=111). Participants were first divided into two age-groups-group Y ($10{\leq}age{\leq}15$, N=54) and group O ($16{\leq}age{\leq}18$, N=57)-because neurocognitive function test tools were different according to age [Wechsler Intelligence Scale for Children (WISC) for 10 to 15-year-old patients, Wechsler Adult Intelligence Scale (WAIS) for 16 to 18-year-old patients]. They were then divided according to their suicidal or violent behavior-non suicidal/violent group (NG), suicidal group (SG), violent group (VG), and both suicidal/violent group (BG). The Child Behavior Checklist (CBCL) was checked for measurement of participants' behavior and the Gordon Diagnostic System was checked for measurement of their attention efficiency. Kruskal-Wallis Test and Tukey test was used to determine the differences in neurocognitive function between groups. Results: O-SG patients showed lower scores on the comprehension subscale of WAIS-III than O-NG patients (${\chi}^2=8.454$, p=.015). O-VG patients showed lower scores on the block design subscales of WAIS than O-SG patients (${\chi}^2=7.496$, p=.024). Y-VG patients showed higher scores in aggressive behavior, externalizing problems, and total problems scores of CBCL. Conclusion: This study showed relationship between specific neurocognitive deficits and suicidal or violent behavior. These relationships were significant in relatively older adolescents.

Purpose: The purpose of this study was to investigate the epidemiologic characteristics of patients who visited emergency departments (EDs) after intentional poisoning in Korea. Methods: This study retrospectively analyzed the data of of 23 hospitals during a five-year period, between 2011 and 2015. We included patients who inflicted injury to themselves - attempt of suicide - by means of poisoning. Results: A total of 18,121 patients visited an ED after intentional poisoning. Among them, 58.3% were females; however, there were more males among those aged 60 years or older. The mortality rate for males was 8.6%, which was 3.1 times higher than that for females with 2.8%. The most common poison was pesticides (35.4%) in males and sedative-hypnotics (44.0%) in females. The most common causative agent of death was pesticide in both sexes (75.2% and 65.3%, respectively). Since the production of paraquat was discontinued in 2011, the number of deaths from pesticide poisoning has decreased. The mortality rate declined in both males and females, from 12.6% and 4.5% in 2011 to 7.1% and 2.1% in 2015, respectively. Conclusion: In this study, we analyzed the epidemiologic characteristics of intentional poisoning, especially the frequency of suicide attempts by gender and age group, the cause of suicide, and the causative agent. This can be used as basic data for establishing policies to reduce and prevent suicide attempts by poisoning.

Purpose: This study reports the clinical features of infant, child, school aged and adolescent patients treated for acute poisoning in nationwide emergency departments (EDs). Methods: We retrospectively analyzed clinical data pertaining to patients under 19 years of age who were treated for acute poisoning in nationwide EDs from 2013 to 2015. The data were collected by the National Emergency Department Information System (NEDIS). All patients were divided into three groups: 'Infant and child group' (0 to 5 years), 'school age group' (6 to 12 years) and 'adolescent group' (13 to 18 years). General characteristics, Korea Standard Classification of Disease $7^{th}$ (KCD-7) codes and results of care were collected. Results: There were 14,500 pediatric poisoning cases during the study period. The distribution of patient age was bimodal with two peaks among infant, child and adolescent group. The proportion of alert mentality at the ED visit of the infant and child group was 99.3%, while that of the adolescent group was 86.4%. The proportion of intentional intoxication was higher in the adolescent group (40.7%) than other age groups. Among children less than 13 years of age, various poisonous substances and therapeutic drugs were common. Conclusion: There were some clinical differences in acute poisoning patients between age groups. It is necessary to establish a preventive plan considering characteristics by age. Since the KCD-7 code has limitations in analyzing the characteristics of poisoning patients, it is necessary to consider the registration system of poisoning patients.

Menarche is a main indicator of sexual maturity which relates to a reproductive function. The onset of the menstrual cycle differs individually and is influenced by many variables such as socio-economic situation, race, genetics, climate, altitude, nutritional status, and physical growth. Among them physical growth has been known to be the most influencing factor, particularly when expressed as body fat designated by weight. This study intended to investigate the body composition of girls around the menarche period and to evaluate the minimal levels of weight and fat percentage needed for the onset of menarche. A total of 101 female subjects, aged 11 to 13 years, were recruited from the 5th and 6th grades of an elementary school, in Mokpo, Korea. The subjects were placed into one of two groups Pre-menarche and Post-menarche groups according to their experience with menarche. Thereafter, the subjects in the Post-group were placed into 4 subgroups based on the number of menstruations they experienced: Post-I (1-3 times), Post-II (4-6 times), Post-III (7-9 times), and Post-IV (> 10 times). The average age at the onset of menarche of the subjects in Post groups was $11.2 \pm 0.6$ years. There were significant differences in the data of anthropometry and body composition between the Pre and Post groups, although the mean ages of both Pre and Post groups were the same. Weight, waist, hip and thigh girths, fat percentage, and lean body mass of the Post groups were significantly higher than those of the Pre group. Height was not significantly different between the groups. Weight was highly correlated with body fat mass (r = 0.92. p < 0.001), fat percentage (r = 0.85, p < 0.001), and body mass index (r = 0.91, p < 0.001) These results indicate that weight, compared with height, reflects body composition well and influences the onset of the menstrual cycle. It could also be suggested that the minimal weight and fat percentage needed for the onset of menarche in Korean females are 41 kg and $17\%\;to\;19\%$, respectively.

Objectives: Korean elderly people are known to consume diets high in carbohydrates low in vegetables compared to other age groups. This study evaluated the chronic disease risks and nutritional status in this group based on the percentage of energy from carbohydrates and the frequency of vegetable intake. Methods: Using the 2007~2009 Korean National Health Nutrition Examination Survey data, except those who were undergoing treatment for chronic disease, final 1,487 subjects aged 65 and older were divided into 4 groups: moderate carbohydrate energy ratio of 55~70% and low frequency of vegetable intake defined as less than 5 times per day (MCLV), moderate carbohydrate ratio and high frequency of vegetable intake more than 5 times (MCHV), high carbohydrate energy ratio above 70% and low frequency of vegetable intake less than 5 times (HCLV), and high carbohydrate ratio and high frequency of vegetable intake more than 5 times (HCHV). All data were analyzed after the application of weighted value, using a general linear model or logistic regression. Results: More than half of Korean elderly consumed diets with HCLV, and this group showed poor nutritional status and lower frequency of intake of most food items, but with no risk of chronic disease such as diabetes, obesity, hypertension, cardiovascular disease or anemia probably due to low intake of energy. On the contrary, MCHV group with a high percentage of energy from fat and protein showed the highest intake of energy and most nutrients, the highest frequency of intake of most of food items and a tendency of high risk of abdominal obesity, being followed by the MCLV group. Meanwhile, HCHV group showed a tendency of high risk of hypertension, followed by HCLV group with low frequency of intake of vegetables compared with the two moderate carbohydrate groups. Conclusions: The results suggested that the percentage of energy from carbohydrate and the frequency of vegetable intake affected the nutritional status, but not significantly affected the risk of chronic disease in Korean elderly. Further studies using more detailed category of % energy from carbohydrates and of type and amount of vegetables with consideration of individual energy intake level, excessive or deficient, are needed to confirm the results.

This study was aimed to examine nutrition knowledge, dietary attitudes, and eating habits of elementary school students and to examine if their characteristics differ by gender. Subjects were 5th and 6th graders of an elementary school (n = 317) in Seoul, and the survey was done during July 2007. Mean height, weight, BMI of subjects was 148.1 cm. 41.7 kg, 19.0, and 14.3% of subjects were categorized as the overweight/obese group. Anthropometric data were not significantly different by gender. Mean score of nutrition knowledge was 14.9 out of 20 showing moderate knowledge levels, and girls scored higher on nutrition knowledge than boys (p < 0.05). Subjects showed knowledge deficit in areas such as nutrients, food groups and specific weight control information. The percentages of correct answers regarding meals for brain function were significantly higher in girls than in boys (p < 0.05). They got nutrition information mainly from mass media and family/relatives. The mean score of dietary attitudes was 41.2 (possible score: 10-50) indicating somewhat positive attitudes, and the score of eating behaviors was 34.8 (possible score: 15-45). Subjects showed problems in eating habits such as having unbalanced diets and snack foods. 82.6% of subjects had unbalanced meals, and these percentages were higher in girls (87.2%) than in boys (78.1%, p < 0.05). Vegetables and fish/shellfish were the most disliked foods. Specific eating behaviors, such as eating slowly, eating grains and having processed foods less frequently, were better in girls than in boys (p < 0.05). Results also showed that majority of subjects need to improve specific behaviors including having diverse foods, eating meals slowly, having meals at regular times, having adequate foods in each food groups, and eating sweets or salty foods less frequently. Only 52.7% of subjects perceived their body images as normal, and 56.4% had experience of weight control. Reasons for weight control were different by gender (p < 0.05). Based on these findings, nutrition education for school children should focus on modifying eating habits or eating behaviors, by suggesting practically applicable methods and providing nutrition information that is interesting and suitable to school-aged children.

Objectives: This study was performed to set easily applicable portion sizes by sex and age for children at the Community Child Centers (CCC) in Korea. Methods: Considering the age and gender specific energy level at Target Patterns for children aged 6-18 years, which were suggested as a part of the 2010 Korean Food Guidance System (KFGS), we set three meal sizes. We reclassified the recommended daily servings of Grains, Meat fish eggs beans and Vegetables group at Target Patterns into three meal sizes, and then calculated the recommended serving per meal. Each proposed amount of food per meal was calculated based on serving size of foods commonly eaten at KFGS, which was then allocated to five meal components; rice, soup stew, protein and vegetable side-dishes and Kimchi. Each proposed amount of food per meal was applied to 173 menus' recipes from CANpro 3.0 as main ingredient's amounts. We cooked the 173 menus at the medium size and measured their weights after cooking. Results: Each recommended serving per meal was 0.75, 0.9 and 1.2 for Grains; 1.2, 1.6 and 2.4 for Meat fish eggs beans; 2, 2.4 and 2.8 for Vegetables by meal sizes. Among five meal components, the ratio of small and large to medium size was 1/5 less and 1/3 more for rice and 1/3 less and 1/3 more for soup stew, protein side-dish and Kimchi, respectively. We suggested the same amount for a vegetable side-dish to encourage vegetable intake. Proper portion sizes per meal of medium were rice 190 g, soup stew 210 g (solid ingredients 60 g), protein side-dish 100 g (meat eggs beans) and 70 g (fish), vegetable side-dish 80g and Kimchi 30 g. Conclusions: Proper portion size per meal suggested in this study may be useful at the CCC where dietitians are not available and the approach could be applicable to the other types of meal services.
