Purpose: Urinary tract infection (UTI) caused by gram-positive uropathogens is usually hospital-acquired and associated with predisposing conditions. However, the incidence of gram-positive bacteria in community-acquired UTIs has recently increased worldwide. We aimed to investigate the clinical significance of UTI and associated genitourinary malformations in young children with febrile UTIs caused by gram-positive bacteria. Methods: We retrospectively reviewed the medical records of 566 patients (age, <1 year) who visited the Korea University Medical Center for febrile UTIs between January 2008 and May 2013. We classified the patients into the following two groups: gram-positive (P group) and gram-negative (N group), according to the results of urine culture. The fever duration; white blood cell (WBC) counts and C-reactive protein (CRP) levels in peripheral blood; and the presence of hydronephrosis, cortical defects, vesicoureteral reflux (VUR), and renal scarring were compared between the two groups. Results: The number of patients with gram-positive bacteria was 23 (4.1%) and with gram-negative bacteria was 543 (95.9%). The most common pathogen was Escherichia coli, and Enterococcus faecalis showed the highest incidence among gram-positive uropathogens. Patients with gram-positive bacteria showed longer fever duration compared to that in patients with gram-negative bacteria (P vs. N, $3.4{\pm}1.2$ vs. $2.9{\pm}1.6$ days, P <0.05). The incidence of VUR was increased in the gram-positive group compared to that in the gram-negative group (P vs. N, 55.6 vs. 17.8%, P<0.05). However, there were no significant differences in other laboratory and radiologic findings. Conclusion: The findings of our study show that community-acquired UTIs in patients younger than 1 year of age, caused by gram-positive uropathogens, can be associated with prolonged fever duration and the presence of VUR.

Purpose: Intussusception is the most common cause of intestinal obstruction in young children. Although intussusceptions are easily treated, some intussusceptions with or without a pathologic lead point (PLP) often recur. In this study, we analyzed the clinical characteristics and prognosis of recurrent intussusceptions (RI), the frequency of the PLP, and correlation between RI with PLP. Methods: The medical records of 144 patients, among 590 patients with intussusceptions who had been admitted to the Department of Pediatrics and Pediatric Surgery of Dankook University Hospital between May 1994 and June 2009 were reviewed retrospectively. Results: The overall recurrence rate of intussusceptions in this study was 9.2%. The mean interval between the initial occurrence and the first recurrent attack was 130${\pm}$175 days (range, 12 hours to 3 years). There was no statistically significant difference in the recurrence rate among patients who underwent air, barium, and manual reduction (p=0.131). Eighty-seven cases (92.6%) of RI had a successful reduction by the use of non-operative techniques. A PLP was present in 18 patients (3.0%). The most common PLP was intestinal lymphoid hyperplasia, followed by Meckel's diverticulum, duplication cyst, intestinal polyp, and adenomyoma. The mean number of intussusceptions was 4.7${\pm}$1.9 in 7 patients with PLP, which was significantly higher than (2.4${\pm}$0.9) patients without a PLP (p=0.023). The mean duration of recurrences was 17.4${\pm}$19.8 months (range, 2 days to 72 months). Conclusion: A careful search for a PLP should be performed to prevent recurrence of intussusception, especially when intussusception has recurred more than three times.

An evaluation of the influence of nutritional health camp for in obese elementary students was assessed. Anthropometric measurement, 24-hour recall of dietary intake, MMTIC(Murphy-Meisgeier Type Indicator for Children) and questionnaire response(nutritional knowledge, nutritional attitude, and self-satisfaction) was documented in 43 obese elementary students(29 boys and 14 girls). The mean age of the elementary students was 11.2 years. The mean height, body weight and obesity index was 144.7 cm, 55.4 kg and 41.0% in boys, and 136.1 cm, 45.2 kg, 40.0% in girls. The mean energy intake was 1,522.4 kcal in boys and 1,494.9 kcal in girls. The subjects taking less than estimated average requirement(EAR) for vitamin ${B_2}$, folate, vitamin C and calcium was over 70%. A considerable number of students(65.1%) showed U band(undetermined character). The students demonstrated a propensity towards increased average nutritional knowledge and self-satisfaction after attending the nutritional health camp. In addition, a significant increase in average nutritional attitude was observed(p<0.001). The results of this study suggest that nutritional health camp positively influenced the nutritional attitude of elementary students.

Purpose: As the coronavirus disease 2019 (COVID-19) pandemic ended, the number of patients with respiratory syncytial virus (RSV) pneumonia increased during the spring/summer of 2022. This study aimed to analyze the clinical features and antibiotic usage of children hospitalized for RSV pneumonia in a recently established general hospital in Sejong city. Methods: In this retrospective review, we included inpatients of the Pediatric Department of Chungnam National University Sejong Hospital diagnosed with RSV pneumonia between March 2022 and April 2023. Patients were divided into 2 groups: with and without antibiotic treatment. Demographic data, initial presentations, and clinical courses were reviewed. Results: A total of 116 patients with RSV pneumonia were hospitalized during this period, of which 102 were analyzed, excluding 14 with underlying diseases or who did not fall within the definition of pneumonia. The median age was 17 months. Diagnoses of bacterial infections (acute otitis media and sinusitis) were documented in 9.8% of cases. Intravenous (IV) antibiotics were administered in 46% of cases. The group receiving IV antibiotics showed higher inflammatory levels (C-reactive protein; CRP), more infiltration on initial chest X-rays, and longer fever duration. There was no difference in the length of hospitalization between the groups with and without IV antibiotics. Conclusions: This study showed a tendency for the attending physician to prescribe IV antibiotics to patients with longer fever duration, pulmonary infiltrations on the initial chest X-ray, and higher CRP levels. However, given the high rate of IV antibiotic usage compared to previous studies, care should be taken in antibiotic use.

Kim, Yong-Hwan is a one of the South Korean major cartoonists between 1940s and 1960s. Kim, Yong-Hwan drew a variety of genres from children's cartoon to current-affair cartoon. Furthermore, Kim, Yong-Hwan took the lead in publishing cartoon magazine and newspaper after the Independence, and has been highly appreciated as a pioneer of Korean cartoon. Kim, Yong-Hwan created many works in the fields of illustrations, Oriental painting, history painting, caricature, etc. After going study for painting to Japan, Kim, Yong-Hwan made his debut as an illustrator called Kita Koji in Japan. However, not much is known about his works in Japan, only there is a simple data about his Japan period and some pieces of illustration during Japan years. In this paper, I examined in detail about Kim, Yong-Hwan's work activity in Japan which has been little known in Korea for a long time. I studied on illustrations in magazines and books which he drew in the name of Kita Koji, on the basis of the data of the National Diet Library of Japan. I could know that Kim, Yong-Hwan worked actively in a diversity of publishers and magazines. In addition, I could realize that many magazines in which Kim, Yong-Hwan drew illustrations were very popular ones. This demonstrates that Kim, Yong-Hwan was much recognized in Japan for his talent. However, a large number of Kim, Yong-Hwan's illustrations were published from late 1930s to mid-1940s. This period was the years that Japan concentrated all her energy for World War II. All the publishing were severely censored during this period. A majority of publishing in this period supported Japanese militarism, and glorified Japan's war policy. Kim, Yong-Hwan's illustrations were no exception, too. It was really sorry about his activity during his Japan period. This essay means a lot to a field of cartoon studies in terms of a collection of materials during Kim, Yong-Hwan's Japan period. Besides, I think that henceforth, this paper can contribute to a follow-up study on Kim, Yong-Hwan' work and his broad background.

Purpose : Baby-walkers are used by many parents because of the convenience they provide in keeping children occupied, quiet, happy, and in stimulating ambulation. But, these devices have more risks than benefits. Therefore, we performed a study to evaluate the effects of baby-walkers on motor development of human infants according to the hours used in a day, total duration(months), and types of injuries associated with the walkers, and to establish effective methods. Methods : 1,045 questionnaires were filled out by parents who had a baby whose aged between 8 months and 15 months that visited local pediatric clinics and medical centers in Chonju and Iksan from May 1, 2002 to July 31, 2002. They were analyzed in a control group that didn't use babywalkers, a low-user group that used baby-walkers less than 2 hours a day and a high-user group that used them more than 2 hours a day. Results : The mean age of the 1,045 babies whose parents responded to the question investigation was $12.6{\pm}2.4$ months. The number of babies who used the baby-walkers were 811(77.6%). Crawling and walking alone were delayed in the high-user group. The parents who knew the side effects of the baby-walkers totalled 392(48.3%). Conclusion : The findings of this study revealed that many parents didn't know the effects of baby-walkers on motor development in their infants and the risks associated with baby-walkers. Therefore, we should educate parents on the risks of baby-walkers and recommend reducing the use of baby-walkers.

This study was carried out to investigate food service management practices in various operation types of child care center in Gyeonggi area of Korea, and to provide basic information for improving food service management policies at child care centers. Self-administrated questionnaires were collected from 102 child care center directors. The statistical analysis was completed using SPSS ver. 18.0 program. Approximately 97.1% of the directors were women. The number of total children were difference in public, private and home care centers respectively (p<0.001), and time of operation was significantly (p<0.01). Only 8.9% of the centers employed a dietitian, whereas 92.5% of the centers employed cook or assistant cook, thus food service was not managed by professionals in most centers. All of the centers had been self-operated and meals were prepared in a conventional manner. In approximately 89.2% of the centers servings snacks twice a day. Menu planner of the centers which have no dietitian was the child care information center (47.5%) or the director (34.7%). In most centers, the directors was also purchasing manager and 36.0% of the center purchased food every day. These results indicated that food service management guidelines need to be established by the child care center type with the government control and financial support. We recommended that they furnish the efficient food service program for food service management.

Due to the relatively high number of members and low income in each family, Wido inhabitants take very low nutrition. The result indicates that nutrition at the present time is generally lower than that of 1973 with the exception of fat. Consequently, the degree of body development of primary and junior high school students has not generally reached the standard in Korea, that was collected from Gyeongido, Korea and from Japan, of the corresponding grade students as well as the Hb content is significantly insufficient. As the body development of 12-year-old children grown at home and nursery, and attending the sports school are compared with that of the Korean standard and Wido students, the body development of Wido students is similar to the Korean standard, and slighly better than that of the sports school students by three years. Health is important as said that health power is nation's power. In order to maintain good health, the normal level of body development and Hb content is necessary for which the recommended daily nutrition for each person should be taken. In addition, the present status and importance of body development and nutrition should be fully educated the primary and junior high school students as well as directly to the inhabitants.

The purpose of this study was to analyze the importance and performance of sanitation management within childcare center foodservice facilities in Gyeongbuk province. The survey involved 248 people who participated in the food hygiene and safety education for childcare center managers in Gyeongbuk province from June to July 2010. A total of 236 survey papers were analyzed statistically by SPSS program. By the method, t-test and importance-performance analysis (IPA) was performed. Among the respondents, facility managers are 40s (41.9%) which accounted the most percentage, and for the type of facility, the largest amount was home (39.9%). The number of preschool children who are under 20 people accounted for 45.3% and food service staffs were accounted for 36.7%. No significant differences were observed for the four items on the IPA, except for the topics "the immediate deal with trash and leftover food" and "minimizing time (within 2 hours) for distribution after cooking" (p<0.001). The average score on the IPA was 4.14 points, and the average score for the importance of the evaluation was 4.49 points out of 5. Finally, childcare facility managers are aware of the importance that is lower than can be done. The results suggest that continuing education is necessary to administrators to manage the health care facility effectively.

Currently, 'National program of dental sealant' has begun in Korea, but various isolation techniques and preparation is performing. The aim of the present study was to compare pit and fissure sealant retention rates between different operators using two different isolation techniques. Additionally, the failed surface was examined. One examiner performed the examination after one year of the initial operation. The population consisted of 119 children(mean age $8.59{\pm}0.772$) of which the total sealed number was 279 permanent first molars. Pediatric dentists sealed 131 molars using the rubber dam isolation technique (Group 1), general practitioners sealed 80 molars using the rubber dam isolation technique (Group 2), and dental hygienists sealed 69 molars using the cotton roll isolation (Group 3). The results were as follows ; 1. The complete retention rate between Group 1 (90.8%) and 2 (85.0%) showed no significant statistical difference (P>0.05). However, there were significant statistical different retention rates between Group 1 and Group 3(64.7%) and between Group 2 and Group 3 (p<0.05). 2. In comparing retention rates between maxilla and mandible, Only Group 3 showed a significantly lower complete retention rate in mandible than maxilla (p<0.05). 3. In failed surface analysis, occlusal failed surface was 58.3%, buccal/palatal failed surface was 41.7%.
