This paper reviews the global effect of the coronavirus disease 2019 (COVID-19) pandemic on the mental health of children and adolescents in South Korea, the U.S., Japan, and China. We reviewed research on deteriorated mental health, including increased suicide, suicidal thoughts, and self-harm. Various studies have shown that students' mental health issues, such as depression and anxiety, have worsened during the COVID-19 pandemic. Furthermore, the number of students who committed suicide has significantly increased in the U.S. and Japan. Factors such as prior mental health status, change in daily routine, reduced physical activity, excessive screen time, overuse of electronic devices, and reduced social support have been reported to have a significant effect. The chain of deteriorating mental health among the youth began at the onset of COVID-19, social distancing, and school closure. As youths began to stay at home instead of going to school, they lost opportunities to connect with their friends or teachers, who could provide support outside of their homes. Young people spent less time on physical activity and more time online, which damaged their sleeping schedule and daily routine. In preparing for the post-pandemic phase, we should thoroughly analyze the long-term effects of the pandemic on youth mental health, while simultaneously tackling current imminent issues.

A 14-year-old girl was admitted to the emergency department for excessive bile-containing vomiting and severe abdominal pain. She had been healthy until she intentionally lost 25 kg over a 6-month period. Thick, bloody bile-mixed food particles were drained from the stomach through a nasogastric tube. Abdominal computed tomography revealed huge stomach dilatation with extensive gastric pneumatosis, possible near rupture, acute pancreatitis, and a very narrow third of the duodenum, indicating superior mesenteric syndrome. Gastrofibroscopy revealed multiple hemorrhagic ulcers and numerous beadlike cystic lesions in the stomach. Laboratory examination results were notable for severe deficiencies in critical nutrients, including iron, zinc, proteins, and prealbumin, as well as undernutrition-associated endocrine complications such as hypothyroidism and hypogonadotropic hypogonadism. Excessive vomiting ceased after the endoscopic removal of stagnant gastric contents. Gastric pneumatosis improved after 3 days of supportive care.

Early childhood caries is a global healthcare concern in developing and industrialized countries. If left untreated, it leads to immediate and long-term complications that affect the well-being and quality of life of concerned families. Therefore, many preventive and treatment approaches are available to the healthcare provider to curb this virulent form of caries. After behavioral interventions, general anesthesia is used in specific settings when a young patient presents with extensive teeth damage and exhibits a lack of cooperation that is incompatible with conventional dental office care. However, without proper follow-up, any positive results might be lost over time.

아동에 대한 관심이 높아지면서 미아방지를 위한 다양한 제도와 제품들이 개발되고 있다. 하지만 여전히 미아 발생률은 줄어들지 않고 있다. 선행 연구의 리서치 결과 국내 유원지에서 미아 발생 시 미아를 찾는데 너무 많은 시간이 소요 되고, 마땅한 미아 방지 프로그램이 없어 방송이나 미아 보호센터에만 의존하는 등 비효율적인 시스템의 정황을 파악할 수 있었다. 본 연구에서는 이러한 현 실태를 개선하고 미아 사건의 빠른 해결을 위해 대전 동물원을 대상으로 미아방지에 효과적인 방재디자인 기반의 웹서비스를 연구하고자 한다.

The paper holds its purpose to analyze the descriptive function and meaning of first person animation which the focalizer, character, and all narrators are indicated as 'I', For the purpose, the following was reviewed; the relation between 'I' as child memorizing the days of childhood as adult and the current 'I' as adult, and the aesthetic effect of experience and sense of the child on the audience reading the narration. The retrospective narrating situation of the adult narrator brings descriptive effect which comes from 'the tension between the experiencing self (self as child) and the narrative self (self as adult). The works focus on the content of child experience through the confession of the adult narrator, but the view of the adult always heading towards 'the present'. That is, the aesthetics contained by the first person narrator is related to endless arousal of the values of hidden and forgotten things. In addition, the descriptive method of child focalizer as 'the subject of experience' brings qualitative change which enables reasoning of the subject as itself, which is free from the view tamed by rational system. Becoming an adult, the lost ability of mimesis brings qualitative change by meeting with the generality of childhood sense. Therefore, it can be known that the meaning the narrator contains in the first person narrator condition of animation links with the degree of aesthetic completion of the work, but also, it is a highly strategic descriptive device which determinately affects even the acceptance of audiences regarding the work.

Purpose: Undernutrition during hospitalization increases the risk of nosocomial infection and lengthens the disease courses. The aim of this study was to evaluate the risk factors of weight loss during hospitalization in children. Methods: All the patients who were admitted in general wards between April and May 2014 were enrolled. Patients aged >18 years and discharged within 2 days were excluded. Weight loss during hospitalization was defined as a decrease in body weight of >2% in 8 hospital days or on the day of discharge. Patients who lost body weight during hospitalization were compared with patients who maintained their body weights. Significant parameters were evaluated by using the multivariate logistic regression analysis. Results: We enrolled 602 patients, of whom 149 (24.8%) lost >2% of their body weight. Complaint of pain (p=0.004), admission to the surgical department (p=0.001), undergoing surgery (p=0.044), undergoing abdominal surgery (p=0.034), and nil per os (NPO) durations (p=0.003) were related to weight loss during hospitalization. The patients who had high weight-for-age tended to lose more body weight (p=0.001). Admission to the surgical department (odds ratio [OR], 1.668; 95% confidence interval [CI], 1.054-2.637; p=0.029) and long NPO durations (OR, 1.496; 95% CI, 1.102-2.031; p=0.010) were independent risk factors of weight loss during hospitalization. The patients with high weight-for-age tended to lose more weight during hospitalization (OR, 1.188; 95% CI, 1.029-1.371; p=0.019). Conclusion: Greater care in terms of nutrition should be taken for patients who are admitted in the surgical department and have prolonged duration of nothing by mouth.

The education of children is one of the most important parts in children's literature. Children's literature, whose implied readers are both children and parents, is a good means to teach how they should behave and interact. Therefore, literary conventions of children's literature tend to be conservative with happy endings or fairy tale elements. Most of the children's literature of the 18th century were read as a conduct book which teaches children good manners and proper behavior, and at the same time served as a guidebook which tells parents how to discipline children. It emphasized the need of discipline to ascertain the hierarchy and order of the family, and cherished the close relationship between parents and children. In the 19th century, the ideal of family becomes more internalized. In the early 20th century, the ideology of family still remained, even though the world wars and economic depressions caused the cracks and collapses of the family. In the later 20th century, the disintegration of the traditional family was accelerated. The ideal of family based on the close relationship between parents and children, has had problems from the start. The attachment and over-closeness became stressful and sometimes could be poisonous. Recent children's literature shows the process of disintegration of the traditional nuclear family, children suffering in the fractured family, children's mental trauma, and nostalgia for the lost family. However, modern children's literature manages to find the lost or ideal surrogate family, and often shows fairy-tale elements such as mystical and heroic child protagonists or helpers who might solve all the difficult problems at once, despite the collapse of the family in reality.

This study aimed to express the experiences of the parents who lost their children by suicides in their own words from their own perspectives by van Manen(2000)'s hermeneutic phenomenological approach. The analysis of the words expressed by the research participants led to the following five fundamental themes. These are 'broken heart, sinner's grief, land of exile and time stood still, pains to be comforted, and days ahead with half-stitched wounds'. Several distinctions are found due to cultural differences from Korean parents. First, whereas the Western parents see the cause of their child's suicide as his/her independent issue, the Korean parents blame themselves entirely. This may have stemmed from the overly inter-dependency between the parents and the child. Second, whereas the Western perspective views the suicide as a type of illness from the individual's depression. The Korean perspective views the suicide as a shame that disgraces the parents or the family. This negative social perspective intensifies the self-blame and social isolation. Third, the Westerners recognize the prevention and responsibility of suicide resting with the society and government, but the Korean society recognize suicide as personal or family matter. Based on the finding above, I proposed a number of practical measures to aid the surviving parents who belong to a group with extremely high suicidal rates.
