Purpose: This study was on the structural analysis of the covariant amount in order to evaluate the suitability of the structural models which can explain and predict the mental health of children on the basis of Bronfenbrenner's ecological theory. Methods: A questionnaire was used to survey 269 children from dysfunctional families out of 5th and 6th grade students from 30 elementary schools in one city and 6 counties, which was analyzed by using PASW Statistics 18.0 and LISREL 8.7 programs. Results: The variable which had influence on the self-esteem was the social support. The variable which had influence on the positive reaction under stress was the stress. The variables which had influence on the negative reaction under stress were stress, and self esteem. The variables which had influence on the mental health were the self-esteem and the negative reaction under stress. The main variables to influence the mental health of children from dysfunctional families turned out to be the self-esteem and the negative reaction under stress to the mental health. Conclusion: Evaluating the suitability of the models, I presented the bases on the practical nursing business. They showed the right directions to the mental health care of children from dysfunctional families.

Objectives: Rwanda reported a stunting rate of 33% in 2020, decreasing from 38% in 2015; however, stunting remains an issue. Globally, child deaths from malnutrition stand at 45%. The best options for the early detection and treatment of stunting should be made a community policy priority, and health services remain an issue. Hence, this research aimed to develop a model for predicting stunting in Rwandan children. Methods: The Rwanda Demographic and Health Survey 2019-2020 was used as secondary data. Stratified 10-fold cross-validation was used, and different machine learning classifiers were trained to predict stunting status. The prediction models were compared using different metrics, and the best model was chosen. Results: The best model was developed with the gradient boosting classifier algorithm, with a training accuracy of 80.49% based on the performance indicators of several models. Based on a confusion matrix, the test accuracy, sensitivity, specificity, and F1 were calculated, yielding the model's ability to classify stunting cases correctly at 79.33%, identify stunted children accurately at 72.51%, and categorize non-stunted children correctly at 94.49%, with an area under the curve of 0.89. The model found that the mother's height, television, the child's age, province, mother's education, birth weight, and childbirth size were the most important predictors of stunting status. Conclusions: Therefore, machine-learning techniques may be used in Rwanda to construct an accurate model that can detect the early stages of stunting and offer the best predictive attributes to help prevent and control stunting in under five Rwandan children.

Purpose: Few studies have been conducted on the recent status of infectious mononucleosis (IM) in Korean children. The aim of this study was to evaluate the recent trend in the clinical manifestations of Epstein-Barr virus (EBV)-associated IM as well as the clinical differences according to age. Methods: A retrospective study was performed on 81 children hospitalized with EBV-associated IM who fulfilled the serological criteria for the diagnosis of EBV infection (viral capsid antigen immunoglobulin M positive). The patients were divided into 3 age groups: <5 years, 5 to 9 years, and ${\geq}10$ years. We evaluated the recent trend in clinical manifestations and the differences in clinical and laboratory findings among the 3 age groups. Results: Thirty (37%) children were under 5 years of age, 38 (46.9%) were 5 to 9 years of age, and 13 (16%) were 10 years of age or older. The differences in the symptoms and signs among the 3 age groups were not statistically significant, except for headache. The mean duration of fever was 7.7 days (range, 0 to 18 days). A comparison of liver enzyme elevation among the age groups showed an association with advancing age (26.6%, 63.1%, and 76.9%, respectively, P=0.04) Conclusion: This study showed that EBV-associated IM in Korean children continues to occur mostly in children under 10 years of age. In children with EBV-associated IM, the incidence of headache and liver enzyme elevation, the duration of fever, and the proportion of females to males were all positively associated with advancing age.

Under the paradigm of 'Eco', the core of sustainability management, this study aims to establish both domestic and international markets and secure competitiveness in the global markets through the development of children's furniture composed of recycled and unharmful materials. Currently, in Europe and in the Western regions, the concepts of 'eco-friendly', 'children', and 'DIY' are well-placed in the daily lives of the people. On the other hand, compared to the domestic demand for eco-friendly children's furniture, the essential approach and the qualitative improvements about the subject are being slowly progressed. Particularly, the process of applying eco-friendly materials and finishing materials to the children's furnitures are mostly in a non-existent state. Thus, in this study, simple application of basic eco-friendly materials such as natural woods or imitation of overseas furniture designs were avoided to create transformable eco-friendly one-touch DIY children's furniture for children's growth and development through the application of eco-friendly processes of technology, design, and other stages of the development process. In other words, under the big category of eco-friendly children's furniture, the furniture was developed through an environmentally-friendly process of universal design that is suitable for children of all ages, and thus, ultimately maximizing the economical effective value and reducing consumption of resources and environmental pollutions.

Measurement of lung function is an integral component of respiratory physiology and of clinical assessment of lung diseases in school age children and adults. Pulmonary function test of infants and children under the age of 2 years have now been standardised and are being used both in research and as an adjunct to clinical management. By contrast, until recegntly, children of preschool age, i.e. between 2-6 years represented a major challenge for pulmonary function test assessment, this particular period commonly being referred to as the 'dark ages' of Pediatric Pulmonology. Measurement of lung function in preschool-aged children is now feasible. However, much work remains to be done in standardizing how these tests are performed, and in understanding the most appropriate role for the various tests in the study of growth and development of the respiratory system and in the clinical management of children in this age group. As the field develops and the knowledge of respiratory physiology in this age group expands, investigation of different and more appropriate algorithm use in preschool children, together with development of more appropriate reference data, may result in improved disease discrimination.

Poor children are a field of causing of various Issues and become a subject of sympathy, concern and anger, against adult's poor such as sleeper outdoors and unemployed to be made a subject of discussion. This study has theoretically investigated the poverty concept, family trait around poor children. And also for understanding the above status, poverty circumstances have been focused children family and shelter-care children. The conclusions are as follows. First, the family of children head was formed with children under fifteen years of age. It was reported that solo families were 26.4% and living together families with relatives were 64.7%. As status of producing causes, parents death was shown the most rate as 49% and abscondence or missing was 31.9%. Second, In the shelter-care aspect, the highest case is a parents-divorce with 42.5%, while children-head case is just shown 0.5%. Therefore, in a child right viewpoint, it needs more systematical/long-range study on children poverty, and some policies for protecting the poverty-children must be established in social policy.

Purpose: This study examined the awareness and attitudes of parents of 5th and 6th graders toward own children smoking. Method: The participants were 766 parents of 5th and 6th graders in 11 elementary schools located in J city. Data were collected through questionnaires, which were constructed to include parents' recognition of harms to their own children cause by smoking, factors which influence their children to smoke, and parental supportive strategies to prevent smoking. Result: The percentage of parents who answered that they did not know if their children were smoking was 94.8%, while the percentage of parents who answered that they knew that their children were smoking was 3.5%. Only 30% of parents had actually spoken with their children about the dangers of smoking. The mean parental recognition of the dangers of smoking was 3.16 points. Parental strategy for preventing and prohibiting smoking with the higher mean scores included forbidding children from entering bars and nightclubs which had the highest scores at 3.55 points; forbidding the sale of cigarettes to children was next at 3.54 points. Conclusion: To prevent children from smoking, the role and attitude of parents is crucial. But the study results show that the role of parental guidance in preventing underage smoking was insufficient and under appreciated. Therefore, more systematic educational programs on preventing underage smoking are essential for parents.

Reduction of the under-5 mortality rate is a target of the Sustainable Development Goals. Therefore, this study aimed to estimate under-5 child mortality rates in 52 low-migration countries using population data. The study utilized population data from the US Census Bureau from 1990 to 2015. The method involved first estimating mortality rates for countries with negligible net migration and then applying these rates to countries with matching mortality profiles, where it is reasonable to assume that migration is negligible for children under the age of 5 years. The highest child mortality was concentrated in the African region, followed by Asia and the Western region. However, steady progress in child mortality trends was concentrated in low-income countries. This simple method demonstrated that child mortality has significantly improved in high-income countries, followed by middle- and low-income countries. To reduce the under-5 mortality rates even further in these 52 countries, there is a need to accelerate equitable plans and policies related to child health to promote children's longevity and survival.

This study was carried out with 343(161 male, 182 female) elementary school children to investigate the relationship between 5th and 6th grade males and females of living in Chuncheon city. The degrees of going without a meal and overeating showed high in breakfast and dinner respectively. Also most children responded that they eat more than usual when they are under stress. After having dinner, 52.8$\%$ of the children ate snacks. 64.7$\%$ of the children have unbalanced diets with the main reason being they don't like the peculiar smell that some foods have. Most children sleep 8 hours and go to school on foot, and 74.3$\%$ of the children enjoy indoor activities in their spare time. The regularity of exercise shows a low level of 39.1$\%$. In weight control, 51.0$\%$ of the children take no interest in it. Thirty percent of the children get their nutrition knowledge from school and the order of average mark of their nutrition knowledge is poor(40.5$\%$), fair(36.4$\%$), and excellent(23.0$\%$). Most children like sweet taste. It is prevalent that the children think instant food is not good for their health, and their preference for instant food is on a fair level. The most popular instant food is in the order of ddogbbokki, ice-cream, kimbap, fried chicken and pork cutlet.
