Purpose: The purpose of this study was to investigate the stress level, coping behaviors and health problems of elementary school children and to compare the level of these three variables according to size of city of residence and to identify the relationship among the three variables. Method: Data were collected by questionnaire from 465 5th and 6th grade elementary school children living in Daegu and North Kyungsang Province. Data were collected between December 1 and 20, 2003 and analyzed using the SPSS program with means, standard deviation, t-test, and Pearson's correlation coefficients. Results: The stress level was significantly higher in children who lived in the big city. The coping behavior score was not significantly different according to size of city, nor was there a difference in the health problems according to size of city. There was a positive correlation among stress level, coping behaviors and health problems. Conclusion: In general, the stress level was significantly different but coping behavior scores and health problem scores were not significantly different according to size of city. Also the elementary school children used more passive coping behavior than active coping behavior. Therefore, strategies to develop active coping behaviors for these children are needed.

Objectives: Although Campylobacter is the main cause for bacterial acute gastroenteritis (AGE), there has been no notable clinical research into it, especially for Korean children. In this study, we share our experience of clinical, laboratory and image findings with Campylobacter AGE. Methods: Between May 2013 and June 2016, children diagnosed as having Campylobacter AGE were retrospectively enrolled in our study. Campylobacter AGE was considered diagnosed when a patient had symptoms of bacterial AGE and a positive Campylobacter result in stool using multiplex PCR. Results: Among 539 patients with suspected bacterial AGE, 31 (5.8%) patients had a positive result for Campylobacter. The average age of the 31 patients was $10.2{\pm}5.0$ years with a range between 1.1 and 16.9 years. Eighteen (58%) of the total patients were hospitalized between June and August. Diarrhea (93.5%), abdominal pain (83%) and fever (83%) were common symptoms. For 20 patients (65%), diarrhea lasted for less than three days, and fever lasted for 2.1 days on average. Among the 20 patients subjected to imaging studies, 12 patients (60%) showed bowel wall thickening on the right side of colon. In blood tests of 30 patients, 22 (73%) and 29 (97%) patients exhibited leukocytosis and elevated C-reactive protein, respectively. During treatment for Campylobacter AGE, prediagnostic empirical antibiotics were used for 6 (19%) patients. All patients recovered without complications. Conclusions: Among the children with suspected bacterial AGE, 5.8% had a positive result on Campylobacter in stool using multiplex PCR. Therefore, we observe that Campylobacter AGE should be considered in school-age children who have diarrhea, fever, and abdominal pain.

Purpose: The purpose of this study was to identify cell phone addiction in school-age children and factors influencing addiction. Methods: The participants were 163 parents of elementary school students in the 1st to 4th grades. Data were collected through self-report questionnaires completed by the parents, and analyzed using the SPSS/WIN 19.0 IBM program. Results: Of the children, 86.5% were reported as being average users, 9.2%, at risk users, and 4.3%, at high risk users. Cell phone addiction in the children was significantly different according to games played by the children and parents' monthly income. Significant factors influencing cell phone addiction in the children were children's self-control, games played by the children, parents' cell phone addiction and parental control for children's cell phone use, explaining 24% of variance in cell phone addiction. Conclusion: The findings indicate that cell phone addiction in school-age children is influenced by parent-related factors as well as personal factors. Therefore approaches to education programs on cell phone use in school-age children should include parent-related factors as well as personal factors of the children.

Temporomandibular joint disorders (TMDs) can occur at any age, including childhood and adolescence, and pain-related TMDs can affect growth and quality of life. In the present study, recent trends in the diagnosis and treatment of TMDs in children and adolescents were analyzed over a 10-year period. Using 10 years of data from the Health Insurance Review and Assessment Service (HIRA) and Jeonbuk National University (JBNU) Dental Hospital, patients between 0 and 19 years of age diagnosed with K07.6 (temporomandibular joint disorders) were analyzed by 5-year bins. Both datasets indicated a higher prevalence in females (1.2-fold in HIRA, 1.5-fold in JBNU) and in ages 15 to 19 years (72.1% in HIRA, 74.7% in JBNU). HIRA reported a 42.3% increase in prevalence per 100,000 people, from 651.4 in 2011 to 927.0 in 2020. JBNU reported K07.66 (masticatory muscle disorders) as the most common diagnosis in subjects under 10 years of age and K07.60 (internal derangement of temporomandibular joint) in those over 10 years of age. In addition, both were treated mainly by a combination of physical therapy and medication, and the treatment rate increased in accordance with age. Because TMDs can affect various structures in the orofacial region and cause pain that tends to differ with age, an early and specific diagnosis appropriate for age is important for treatment. Therefore, pediatric dentists need to promptly recognize TMDs in children and adolescents and consult with specialists as the prevalence increases.

This study aimed to explore the trajectories of computer game use of school age children and to identify the related predictors. The data for this study used Korean Children and Youth Panel data covering from the second year to the sixth year of elementary school. A total of 1,959 participants were analyzed. Latent class growth model was employed to explore the trajectories of computer game use and multinomial logistic regression was conducted to identify the significant predictors. Main results indicated that three types of trajectories were identified: low game using group, high initial using-fluctuating group, and high increasing game using group. Each group was found to be associated deferentially with sex, aggression, attention deficit, main caregiver's education, siblings, parent absence after-school, neglecting, family income, family trip, school grades, and peer relationship. Based on these findings, this study emphasized the importance of predictive intervention for the game user among early school age children and suggested useful practical strategies.

This study examined the developmental characteristics of friends and disliked peers in 169 children and adolescents, including 44 preschool children, 43 primary school, 42 middle school, and 40 university students. Their descriptions of 2 same gender friends and 2 disliked same gender peers were categorized with an 81 category coding system. Comparisons across age and sex were made by a cross-tabulation test. Results showed that the reported characteristics of friends and disliked peers varied by age, but there was no sex difference. That is, younger children liked their friends because they played together, their friends were generous and attractive, but older children liked friends because they had some similarity, were reliable allies, caring and concerned. Younger children's disliked peers were aversive, aggressive and hyperactive while older children's disliked peers were dissimilar and snobbish.

Mathematics education starts from learning the concept of number. How the children at the beginning of school age learn the concept of natural number is therefore important for their future mathematics education. Since ancient Greek period, the concept of natural number has reflected various mathematical-philosophical points of view at each period and has been discussed ceaselessly. The concept of natural number is hard to define. Since 19th century, it has also been widely discussed in psychology and education on how to teach the concept of natural number to the children at the beginning of school age. Most of the works, however, were focused on limited aspects of natural number concept. This study aims to show the best way to teach the children at the beginning of school age the various aspects of natural number concept based on activistic perspective, which played a crucial role in modern mathematics education. With this purpose, I investigated the theory of the activistic construction of knowledge and the construction of natural number concept through activity, and activistic approaches about instruction in natural number concept made by Kant, Dewey, Piaget, Davydov and Freudenthal. In addition, I also discussed various aspects of natural number concept in historical and mathematical-philosophical points of view. Based on this investigation, I tried to find out existing problems in instructing natural number to primary school children in the 7th National Curriculum and aimed to provide a new solution to improve present problems based on activistic approaches. And based on activistic perspective, I conducted an experiment using Cuisenaire colour rods and showed that even the children at the beginning of school age can acquire the various aspects of natural number concept efficiently. To sum up, in this thesis, I analyzed epistemological background on activistic construction of natural number concept and presented activistic approach method to teach various aspects of natural number concept to the children at the beginning of school age based on activism.

The purpose of this study was to analyze the effect of home related variables like socio-demographic variables, parent-child communication, and concern for children's education on children's school adjustment. The data was collected from 287 elementary school children living in Gyunggido. Measurement scales included the children's school adjustment inventory, the questionnaire of the socio-demographic variables, the parent-child communication index, and the parent's concern about children's education index. Results showed that children's school adjustment was significantly effected with regard to: father's age, father's education, mother's education, income, and mother's job. Correlation analysis indicated that parent-child open communication was positively correlated to children's school adjustment; that is the relationships with teachers and with friends, study at school, and rule of school. As well, parent-child problematic communication was negatively correlated to all of the school adjustment variables. Parent's concern about children's education indicated positive correlations with all of the school adjustment variables. It was also found that: parent's concern about children's education, parent-child open communication, parent-child problematic communication, mother's education, and income were significant predictors of the children's school adjustment.
