Elevated plasma homocysteine is an independent risk factor for the development of cardiovascular disease. Exercise is generally believed to reduce the plasma homocysteine levels and therefore, being beneficial for cardiovascular disease (CVD). However, there is a possibility that athletes undergoing strenuous training and competition which increase oxidative stress may suffer from increased plasma homocysteine levels. The purpose of this study was to investigate the influence of endurance training on the plasma concentrations of B vitamins and homocysteine in 23 male adolescent field hockey players. Data collection and blood sampling was performed during the training period and non-training period. Following the training period, significant changes in energy and vitamin B6 intakes were observed in these subjects. Plasma vitamin B2, pyridoxal phosphate (PLP) and homocysteine levels were significantly higher during the training period than non-training period, whereas no difference was observed in plasma folate and vitamin B12 levels. Positive correlation was observed between plasma folate and folic acid intakes. When energy, B vitamin intakes were adjusted there was a significant negative correlation between plasma homocysteine levels and plasma riboflavin, folate and vitamin B12 levels. In conclusion, it is suggested that athletes with oxidative stress by strenuous exercise may need B vitamins since riboflavin, folic acid and vitamin Bl2 were shown to be negatively correlated with plasma homocysteine in athletes during the training period.

Objectives: This study aimed to investigate the clinical characteristics of adolescents hospitalized through the emergency room for intentional self-harm or suicide attempts. Methods: This retrospective study used data from the Korean National Hospital Discharge In-depth Injury Survey conducted between 2006 and 2018 for individuals aged 10-24 years. The clinical characteristics of the patients were analyzed and compared across sex and age groups using the Rao-Scott chi-square tests and multiple logistic regression analysis for complex survey data. Results: The most common psychiatric diagnosis was mood disorder (22.0%), and more female patients were diagnosed with it than male patients (p=0.010). The 19-24 years age group was diagnosed with mood disorder the most compared to other younger groups (p=0.012). Male patients used lethal methods more than female patients (p=0.008), and the 19-24 years age group used more drug poisoning and cutting or piercing (p<0.001) for intentional self-harm or suicide attempts than younger groups. Conclusion: Adolescents hospitalized for intentional self-harm or suicide attempts showed significant differences in clinical characteristics across sex and age groups. These findings suggest that measures for preventing self-harm or suicide attempts need to be differentiated according to the sex and age of adolescents.

This study was carried out to evaluate nutritional quality of the dosirak severed by 3 Dosirak manufacturing establishment in Kangnung. The subjects of this study came from 3 different male high schools in Kangnung. The portion amounts of Dosirak were weighed and the food intake was measured by substracting the leftover from the averaged portion amount. The leftover was measured by a modified aggregate selection plate waste measurement technique. The nutrient intakes were analyzed by a computer aided nutritional analysis program for professionals(CAN pro). The menu of the dosirak was too simple. The total amount of Dosirak was 714g and the percent of plate waste was 714g and the percent of plate waste was 7.2%. The male high school students were taking adequate energy, but the nutrients which did not meet 75% of the 1/3RDA(Recommended Dietary Allowances) were Ca, Fe, and vitamin B$_2$.

In response to the global coronavirus disease 2019 (COVID-19) pandemic, vaccines were developed and approved quickly. However, numerous cardiovascular adverse events have been reported. We present two adolescent cases who developed a hypertensive crisis following NT162b2 mRNA COVID-19 vaccination. Patient 1 was an 18-year-old male and his systolic blood pressure was 230 mmHg one day after the second vaccine. He was obese. No secondary cause of hypertension other than the vaccine was identified. Patient 2 was an 18-year-old male who complained with palpitation after the first vaccine. His blood pressure was 178/109 mmHg. He had autosomal dominant polycystic kidney disease. Both were treated with continuous infusion of labetalol followed by losartan, and blood pressure was controlled. Patient 2 received second vaccination and his blood pressure did not rise. It is warranted to measure blood pressure in adolescents at high risk of hypertension after NT162b2 mRNA COVID-19 vaccination.

Objective: The purpose of this study was to identify the longitudinal relationship between child maltreatment and adolescent suicidal ideation. Several studies suggest that child maltreatment is associated with adolescent suicidal ideation. However, these studies have not focused on the duration of child maltreatment. Methods: Participants were 420 adolescents (52.6% male; 47.4% female) involved in the Korea Welfare Panel Study. Data were collected via youth self-report in 2006, 2009, and 2012. A self-report assessment of children and youths' experiences of physical, emotional, or neglect had been surveyed longitudinally. Questionnaires on adolescent suicidal ideation were answered in 2012. A growth mixture model and multiple regression were conducted using Mplus 5.21. Results: The study results showed that 93.5% of the children had experienced no maltreatment; 6.5% had experienced increasing maltreatment longitudinally. The trajectory of increasing maltreatment was positively associated with adolescent suicidal ideation. Conclusion: These results show that children suffering from chronic maltreatment are subject to a high risk of suicide and therefore require continuous supervision and management.

The purpose of this study is to examine adolescent future orientation in relation to education, work and career, and marriage and family. This study also explores the effects of adolescent future orientation in relation to their psychosocial characteristics: self-esteem, self-control, scholastic performance, and sexual permissiveness. Data were collected from 345 students in the second grade (male: 166, female: 179) of two middle schools in Seoul, Korea. Scale for adolescent future orientation was formulated based on literature review. The major findings of this study were as follows. Adolescents were found to be more future-oriented in the areas of work and career and in the area of marriage and family than in the area of education. Several hierarchical multiple regression analyses were also performed to examine the contribution of socio-demographic characteristics and future orientation to predictions of adolescent psychosocial characteristics. This study found that adolescent future orientation significantly predicted their self-esteem, self-control, and scholastic performance, while having no significant influence on sexual permissiveness.

본 연구의 목적은 남자 중학생과 아버지 사이의 관계에 미치는 요소들을 탐색하고자 한 것이다. 본 연구의 가설은 아버지에 대한 지각, 애착, 아버지의 나이와 음주력, 학력 등이 남자 중학생의 자기존중감, 기분, 성역할, 학업성취, 학교생활의 만족에 영향을 미친다는 것이다. 이를 위하여 우울감과 자기존중감, 아버지에 대한 태도 등에 관련된 자기보고형 설문지를 이용하였다. 수원시내 일 중학교를 통하여 대상군을 선정하였으며 196명에게 조사를 시행하였다. 남자청소년과 아버지의 관계에서 자기존중감, 성역할, 애착은 부자관계에 영향을 미치는 것으로 나타났고 아버지의 학력, 음주력, 나이는 부자관계에서 유의미한 것으로 나타나지 않았다. 또한 아버지의 과보호는 남자중학생에게 부정적인 영향을 주는 것으로 나타났다. 본 연구는 여러 가지 제한점을 갖고 있다. 첫 번째로 표본집단이 아닌 소수의 일 집단이라는 점과 둘째로 선행연구가 부재하여 충분한 문헌비교와 고찰이 되지 않았다는 점이며 셋째로 원인분석이 아니라 상관분석이라는 점이다.
