In modern times, children's trauma is increasing every year because of car accidents and life environment changes. There is a limit to prevent traumatic damage for oral cavity organization. The fundamental data of trauma treatment and prevention will be presented through the survey and analysis of traumatic teeth damage. I examined 113 patients from Oct. 4th, 2000 to Feb. 27th, 2004 at Dept. of Children's Dental Clinic, Kangnung National University. The results are as follows. (1) The trauma frequency of male subjects is higher than that of female at a rate of 2.05:1. The average age is 5.27 for men and 5.27 for women. The highest percentage of trauma patients is among 2 year old children. It is 21.2%. (2) A patient survey was taken at a trauma treatment hospital. On the first day 34.4% of the patients had come to receive treatment of their first set of teeth. However, after a week, 38.8% of the patients had received treatment on their permanent teeth. (3) As a result of falling, 59% of patients needing treatment on their first set of teeth. 55.1% of patients is permanent teeth. As a result of bump against physical solid, 26.6% of patients is the first set of teeth and 26.5% of patients is permanent teeth. (4) Teeth damage happened at home. 42.1% were male. 35.1% were female. According to trauma, 59.4% of teeth damage happened at home. 28.6% of permanent teeth damage happened at school or kindergarten. (5) According to trauma, the number of teeth damaged was in the first set of teeth are as follows: 56.3%, one-31.3%, three or four-6.3% each. For permanent teeth: two-46.9%, one-28.6%, four over-16.3% and three-8.2%. Over four teeth is larger number for permanent teeth. (6) 56% of first set of teeth patients and 43.4% of permanent teeth patients were male. 56.8% of first set of teeth patients and 43.2% of permanent teeth were female. Trauma happened to both male and female frequently in the first set of teeth. (7) Most of the tooth damage which was in the first set of teeth and permanent teeth was done to the upper jaw. 75% of patients are the first set of teeth. 63.8% of patients are permanent teeth. Trauma is very high in the two mid teeth of the upper jaw. (8) According to trauma survey, 30.2% is from impulse. 28.0% is from crown fracture, 14.7% is from depression. 8.9% is from concussion. 7.1% is from full dislocation of a joint. 2.2% of patients are extrusion. 1.8% is from displacement. According to teeth damage trauma, 35.8% is pulse in the first set of teeth. The breaking of the crown of a tooth happened a lot in permanent teeth. (9) According to data, 43.2% of teeth damage in the first set of teeth goes without treatment. In permanent teeth, it is 38.9%. After treatment, 22.0% of first set of teeth treatment requires a dental pulp treatment. In permanent teeth, which is used for temporary acid etching resin restoration.

This paper describes the development of a system and algorithms for high-quality welfare services by recognizing behavior development indicators (activity, sociability, danger) in children aged 0 to 2 years old using action recognition technology. Action recognition targeted 11 behaviors from lying down in 0-year-olds to jumping in 2-year-olds, using data directly obtained from actual videos provided for research purposes by three nurseries in the Gwangju and Jeonnam regions. A dataset of 1,867 actions from 425 clip videos was built for these 11 behaviors, achieving an average recognition accuracy of 97.4%. Additionally, for real-world application, the Edge Video Analyzer (EVA), a behavior analysis device, was developed and implemented with a region-specific random frame selection-based PoseC3D algorithm, capable of recognizing actions in real-time for up to 30 people in four-channel videos. The developed system was installed in three nurseries, tested by ten childcare teachers over a month, and evaluated through surveys, resulting in a perceived accuracy of 91 points and a service satisfaction score of 94 points.

This study aims to analyze effects of mothers' socioeconomic features, and knowledge and behavior of oral health on experience and purpose of using dentistry. By survey to 103 mothers of 5-6 year old children, who use day care centers in seoul, the results are obtained as follows: 1. As for the rate of experiencing dental care classified by its purpose, 56.7% for dental treatment, 23.3% for regular check-up and 20.0% for precaution 2. There was no significant difference of correlativity between mothers' socioeconomic features and knowledge of oral health and experience of using dental care, while the lower rate of using dental floss, the higher rate of experiencing dental care(p < 0.01). 3. In respect of correlativity between mother's socioeconomic features and purpose of using dental care, the purpose of regular checkup was high in a group of mothers between 33 and 35 years old(71.4%) by ages and in a group of mothers who graduated from college(57.1%) by academic background(p < 0.05). 4. In correlativity between mothers' behavior of oral health and purpose of using dental care, the result showed that the higher the rate of using dental floss was, the higher the rate of experiencing dental care for a regular check-up was(p < 0.001) and the higher the rate of using fluoride dentifrices was, the higher the rate of using dental care for cure was(p < 0.05). 5. Multiple regression based on dependent variable of experience in using dental care showed that average monthly income(less than 2,500,000 won) was significant explanatory factor with 65% of explanatory variance. On the other hand, multiple regression based on dependent variable of purpose of using dental care showed that vocation(professional job) and age(between 33 and 35 years old) was significant explanatory factor with 70% of explanatory variance for a regular check-up, age(between 33 and 35 years old) and average monthly income (less than 2,500,000 won) was significant factor with 78% of explanatory variance for precaution and age(less than 32 years old) was significant explanatory factor with 33% of explanatory variance for treatment.

To investigate the response rate for family examination and the morbidity of family members, we reviewed the medical records of 1,525 tuberculosis patients at health center of Sunsan county in Kyungpook province from January 1981 to December 1990. The response rate for family examination in the first period(1981-1985) was 20.0%, and that in the second period(1986-1990) was 78.8%. The response rate for family examination was rapidly increased with the year. The kinship between the tuberculosis patients and examinees was very closely related with the response rate of family examination. The radiological finding was closely related with rate for family examination was 63.0% in the children of patients, 28.9% in wives or husbands of patients, 28.8% in other relatives and 19.9% the morbidity rate of family examinees. The severe the radiological finding, the higher the tuberculosis morbidity rate of family examinees. The prevalent rates of family examinees were 6.2% in parents, 4.3% in wives or husbands, 1.1% in children, and 1.5% in other relatives of parents. The results of this study suggest that the response rate for family examination should be increased especially for the old people, such as parents of tuberculosis patients.

There are orthodontic treatment which involves tooth movements and orthopedic treatment which involves skeletal movement. In childhood and adolescence, especially for the treatment of orthopedic treatment, the evaluation of bone maturity and growth potential is very important. The purpose of this study is to assess the developmental stage and to compare the amount of mandibular growth with cephalometric radiographs and hand-wrist radiograph in 6 to 13-year-old children with normal occlusion. The results are as follows : SMI and CVM showed a significant correlation (p < 0.05). Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn increased with increasing maturity of hand-wrist and Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn increased with increasing maturity of cervical vertebrae maturation. Also Ar-Go, Co-Go, N-Go, S-Gn, N-Me, Co-Gn, Go-Me, Go-Gn showed a significant correlation with each of the cervical vertebrae maturation stages and hand-wrist maturation stages (p < 0.05). These results suggested that mandibular growth had a significant correlation with cervical vertebrae maturation stages and hand-wrist maturation stages.

Hemolytic uremic syndrome (HUS) is the most common cause of acute renal failure in children younger than 4 years and is characterized by microangiopathic hemolytic anemia, acute renal failure, and thrombocytopenia. HUS associated with diarrheal prodrome is usually caused by Shiga toxin-producing Escherichia coli O157:H7 or by Shigella dysenteriae, which generally has a better outcome. However, atypical cases show a tendency to relapse with a poorer prognosis. HUS has been reported to be associated with acute lymphoblastic leukemia (ALL) in children. The characteristics and the mechanisms underlying this condition are largely unknown. In this study, we describe the case of an 11-year-old boy in whom the diagnosis of ALL was preceded by the diagnosis of atypical HUS. Thus, patients with atypical HUS should be diagnosed for the possibility of developing ALL.

Objective : The purpose of this study was to investigate the effects of sensory diet home program for children with autism spectrum disorder who have sensory defensiveness and explore how this intervention affect to sensory modulation and social interaction ability. Methods : The subject of this case study was a 12-year-old girl with autism spectrum disorder who was struggling with her sensory modulation problem. Parent interview and evaluations were conducted and subject-tailored sensory diet home program was made by the therapist. Parent education for the home program was provided to parents and everyday, 3 times, 30minutes of home program activities were conducted to the child for 23 days. Adolescent/Adult Sensory Profile and Social Maturity Scale were measured at pre and post intervention and parent wrote daily observation record about child during the intervention. Results : After the intervention, Low Registration, Sensory Sensitivity, Sensation Avoiding area of Adolescent/Adult Sensory Profile included to the normal range and the scores of the Social Maturity Scale improved. Conclusions : Child's sensory defensiveness was relieved and sensory modulation and controling emotion ability were improved. While there was significant improvement for sensory modulation and social interaction ability, this was a case study and there was only one subject. So we need to study with larger sample size to generalize this intervention's effectiveness.

The fundamental vocal frequency is produced by simple vibration of the whol length of the vocal folds and is one of the most important single parameters in determining the eventual characteristics of the voice. Authors measured the external laryngeal size, fundamental frequency in 3rd decades adults and about 10-year old children for use them as the base of diagnosis and treatment of laryngeal disease. Results were as follows: 1 In adults, mean external laryngeal size was 37.8$\pm$3.15 mm in male and 31.0$\pm$3.19 mm in female, and the mean fundamental frequency were 117.8$\pm$ 10.09 Hz in male and 220.26$\pm$13.75 Hz in female. (p <0.05) 3. In children, mean external laryngeal size was 25.67$\pm$4.53 mm in male and 27.28$\pm$2.77 mm in female, and mean fundamental frequency were 225.88$\pm$15.89 Hz in male and 239.25$\pm$15.92 Hz in female. (P <0.01) 5. In adults, the external laryngeal size was correlated with fundamental frequency and it was statistically significant.(r=0.48)

Cytomegalovirus (CMV) disease is rare in children who receive anticancer chemotherapy and have no history of stem cell transplantation (SCT). We report a case of CMV retinitis that developed during maintenance chemotherapy for acute leukemia. A 7-year-old boy developed decreased visual acuity and persistent pancytopenia during maintenance chemotherapy. Laboratory investigations initially showed significant CMV antigenemia (51 positive cells/200,000 leukocytes); however, antiviral therapy was not deemed necessary in this patient who had no history of SCT. CMV antigenemia worsened to 170 positive cells/200,000 leukocytes over 3 weeks. Ophthalmological examination revealed multiple bilateral retinal infiltrates and granular lesions. He was diagnosed with CMV retinitis and was treated with a 4-week course of intravenous ganciclovir and intravitreal injection of ganciclovir 6 times, followed by a 1-month course of orally administered valganciclovir. A CMV antigenemia assay showed negative results, and follow-up fundoscopy revealed lesser retinal infiltration after the sixth intravitreal ganciclovir injection. Future studies should focus on the development of standardized screening methods and preemptive therapeutic strategies for CMV disease in high-risk children.

Gastrointestinal involvement occurs in two thirds of children with Henoch-Sch$\"{o}$nlein purpura (HSP) and intussusception is by far the most common abdominal complication. Intussusception in HSP almost originates in the small bowel, which is in contrast with idiopathic intussusception. Earlier diagnosis and prompt treatment of intra-abdominal complications can reduce the mortality and ultrasound is the imaging modality of choice in evaluation the bowel manifestations of HSP. We report a case of jejuno-jejunal intussusception associated with HSP in a 5-year-old boy who presented with diffuse abdominal pain and vomiting after a few days of HSP onset. Abdominal ultrasound demonstrated intussusception in the jejunum with well defined target appearance because of the thickened intussusceptum, which disappeared on the computerized tomographic examination checked approximately 24 hours later. A brief review of literature was made.
