Purpose: This study aimed to identify the pathogens of bloodstream infection in children with underlying hemato-oncologic diseases, analyze susceptibility patterns, compare temporal trends with those of previous studies, and assess empirical antimicrobial therapy. Methods: Retrospective review study of children bacteremia in hemato-oncologic diseases was conducted at Seoul National University Bundang Hospital from January 2013 to July 2023. Results: Overall, 98 episodes of bacteremia were observed in 74 patients. Among pathogens isolated, 57.1% (n=56) were Gram-positive bacteria, 38.8% (n=38) were Gram-negative bacteria, and 4.1% (n=4) were Candida spp. The most common Gram-positive bacteria were coagulase-negative staphylococci (n=21, 21.4%) and Staphylococcus aureus, (n=14, 14.3%) whereas the most common Gram-negative bacteria were Klebsiella pneumoniae (n=16, 16.3%) and Escherichia coli (n=10, 10.2%). The susceptibility of Gram-positive bacteria to penicillin, oxacillin, and vancomycin was 11.5%, 32.7%, and 94.2%, respectively and the susceptibility of Gram-negative bacteria to cefotaxime, piperacillin/tazobactam, imipenem, gentamicin, and amikacin was 68.6%, 80%, 97.1%, 82.9%, and 91.4%, respectively. Methicillin-resistant S. aureus was detected in 1 strain and among Gram-negative strains, extended spectrum β-lactamase accounted for 28.9% (12/38). When analyzing the antibiotic susceptibility and empirical antibiotics, the mismatch rate was 25.5% (n=25). The mortality rate of children within 30 days of bacteremia was 7.1% (n=7). Conclusions: Empirical antibiotic therapy for bacteremia in children with hemato-oncologic diseases should be based on the local antibiogram in each institution and continuous monitoring is necessary.

Objective: The purposes of this study were to analyze the radiation doses for pediatric abdominopelvic and chest CT examinations from university hospitals in Korea and to establish the local diagnostic reference levels (DRLs) based on the body weight and size. Materials and Methods: At seven university hospitals in Korea, 2494 CT examinations of patients aged 15 years or younger (1625 abdominopelvic and 869 chest CT examinations) between January and December 2017 were analyzed in this study. CT scans were transferred to commercial automated dose management software for the analysis after being de-identified. DRLs were calculated after grouping the patients according to the body weight and effective diameter. DRLs were set at the 75th percentile of the distribution of each institution's typical values. Results: For body weights of 5, 15, 30, 50, and 80 kg, DRLs (volume CT dose index [CTDI_vol]) were 1.4, 2.2, 2.7, 4.0, and 4.7 mGy, respectively, for abdominopelvic CT and 1.2, 1.5, 2.3, 3.7, and 5.8 mGy, respectively, for chest CT. For effective diameters of < 13 cm, 14-16 cm, 17-20 cm, 21-24 cm, and > 24 cm, DRLs (size-specific dose estimates [SSDE]) were 4.1, 5.0, 5.7, 7.1, and 7.2 mGy, respectively, for abdominopelvic CT and 2.8, 4.6, 4.3, 5.3, and 7.5 mGy, respectively, for chest CT. SSDE was greater than CTDI_vol in all age groups. Overall, the local DRL was lower than DRLs in previously conducted dose surveys and other countries. Conclusion: Our study set local DRLs in pediatric abdominopelvic and chest CT examinations for the body weight and size. Further research involving more facilities and CT examinations is required to develop national DRLs and update the current DRLs.

This study is to examine current child care support policies and their limitations and to make some suggestions by means of statistics and previous literature. Major findings are as follows: First, As the women have younger children, the effect is more negative. Second, a maternity leave of Korea is 90 days, which is below ILO standard. Moreover, it is not well supported by the companies they work for. Third, the increasing number of men has spent a paternity leave since the pertinent law was enforced in 2001. The rate of spending the leave, however, is not as high as expected, because it has not yet been decided whether the leave would be paid or not. Lastly, the number of the employer-supporting child care center is rather few due to the legal standard of the facility and the expense that a company should cover. Only 46.5% of the companies that has been appointed to obligatorily establish the center now operate the facility. Therefore, child care support policies should be reformed or improved to help reduce married women's child care burden obviously hindering women from being employed, and this will consequently promote their economic activities. It is also urgently required to expand the application of the parental leave in terms of both object and scope. It is important that employers and employees get ready to compromise each other on the wage issue during the leave. In addition, the flexibility in period and form of the parental leave and the connection of working places with local community for better child care service must be taken into consideration.

The comparative study of the administration policy that the government and the local self-governing body have enforced to a handicapped child and the family, was made in South Korea and Japan. As data, I utilized brochures distributed to a handicapped child's guardian in the government publication, health center, and hospital of both countries and the homepage that each organization manages. With the investigation of (1) the handicapped child's present condition, population and entering-school situation, (2) the organization which can consult about a juvenile entering-school problem, (3) the public service with which the parents of handicapped child, or a handicapped child are provided and (4) the feedback surveys of (3)’s services, the followings were proved. In (1), the handicapped child's population and their school attendance are not be specified by the South Korea side. In (2), a private consultation organization is mainly opened and be hard to say that use is simple from the little of a kind. In (3), there is almost nothing than rehabilitation education as the administration policy, which is universally held for the handicapped child. Besides they cannot receive freely the education. In (4), it became clear not to carry out. The improvement from the direction of both hard and soft aspects - the institution of basic education for the handicapped child who lives in all areas and the equal opportunity to all children - is called for urgently.

In the present study, we examined global and local characteristics of eye movements while 17 Korean third-graders read a Korean story and an expository text. In story reading, children fixated for about 213ms at an eojeol(word cluster), made a forward saccade of about 3.6 characters to the next eojeol, and regressed backward at 30.8% on average. In expository text reading, children fixated for about 214ms at an eojeol, made a forward saccade of about 3.3 characters to the next eojeol, and regressed backward at 31% on average. In addition, the effects of eojeol length, word frequency and landing position were examined. The gaze duration in the long ejoels was longer than in the short eojeols. In a further analysis where the repeatedly used eojeols were excluded, the eojeol length effect appeared in the low-frequency words, but seemed to disappear in the high-frequency words. In terms of landing position, the eyes seemed to land near the center of an eojeol more frequently than on the boundaries. When the eyes landed at the boundary of an eojeol, the eyes tended to fixate the eojeol again.

Thus, I studied Health services supplied by local health centers and the requirements of the inhabitants visiting the health care facilities. The purpose of this study was to provide basic material for the establishment of Health care policy and the development of health care businesses. The target places for this study were 4 health centers; Chungrang-Gu, Nowon-Gu, Eunpyung-Gu, Songpa-Gu, with 509 mothers who were visiting the Centers. The question items of this study concerned a total of 124 health-related services provided by the Health Centers. The data was collected for a total of 92 days; July 1st~September 30th, 1999. 800 questionaries were distributed and 559 answered, 509 were analyzed finally. The collected data were processed using the SAS program to get mean, standard deviation, percentage. Open questions were made to reveal the opinions of mothers using the health care center. The results were as follows : 1. Among the participants of the study, 49.7% were 25~29 years of age, 84.3% were house wives by current occupation, 56.2% were from 4~6 person households. 52.1 were educated at a high school level, and 43.6% were educated at a collage level. 2. The highest percentage(53.6%) of the users were spontaneous in their utilization of health care center. The major reason for using the Health care center is that it is free to 65.8% of those covered and of low cost to 19.3% of those covered. 3. The satisfaction level of those using the health care center appeared to be generally high. The general average value showed up as $3.027{\pm}0.519$. 4. The level of recognition of the value of the heath care center services was high, particularly in the basic item of diagnoses of pregnancy, particularly in the basic item of diagnoses of pregnancy. However, the satisfaction level of health care education In pregnancy is low at 20~40%. In the meantime, the level of recognition in breast- feeding benefits is high at 76.8%. 5. The rate of realizing health care center's service campaign was generally low at 10~20%. 41.3 of the people knew the advertizing material of the health care centers. 32.4% of the people knew the advertizing material of the health care centers. 32.4% of the people knew the campaign of health care center for importance of breast-feeding benefits. 30.1% of the people knew the campaign for testing congenital mechanism disease. In the meantime about 50% was recognised the health care centers campaign for the importance and time of infants vaccination. 6. The need for enhancement of health care center services was shown to be high as $3.266{\pm}0.676$ as an average, chicken pox vaccination being the most highly requested at $3.565{\pm}0.587.$. 7. Among the open questions, the additional service to be provided were as follows ; increase of campaign of health care center services, furnishing advertizing books in public locations, providing shuttle bus service to the health care centers, extension of desire for preventative injections, rest and play areas for the children of the families serviced, consultation rooms, etc.

Pumasi and Cooperative Child Care Sharing have had positive results among participants and show possibilities of spreading out to the community in general. However, performance was not proved where it is clarified, and the experience of 23 local Healthy Family Support Centers have that ran the demonstration project were unable to be collected. It is the point of time when the initial backing up is important but the centers do not have the systematic support. Therefore, this research presents an effective management plan through qualitative research involving Pumasi participants and person in charge. The operation strategies by the stage of the project were as follows: First, in the beginning stage, the person in charge establishes the target and vision of the project. Second, when comprising the Pumasi team, it was necessary to consider their characteristics according to the team organization subjects. Third, it is necessary to extend the turn-off time and provide many programs so that the various populations can participate. Fourth, in the advertising step, word of mouth and individual contact needs to be utilized. Fifth, in a medium or small city or an urban-rural complex area, the person in charge should support the participants' Pumasi activities. Sixth, various programs such as a passive and active parent education program and Pumasi education program for the leader needs to be provided for the activation of Pumasi activities. Lastly, a cooperative child care sharing location needs to be constructed by the duality system of the base space and outer space. In this location, the inside play space for the children is essential.

Purpose: We investigated the distribution and antimicrobial resistance of pneumococcal isolates from hospitalized children at Asan Medical Center for recent 4 years, and aimed to recommend proper choice of empirical antibiotics for pneumococcal infection. Methods: From March 2014 to May 2018, children admitted to Asan Medical Center Childrens' Hospital with pneumococcal infection were subjected for evaluation of minimal inhibitory concentration (MIC) for ${\beta}-lactams$ and macrolide antibiotics. Patient's age, underlying disease, gender were retrospectively collected. Using Monte Carlo simulation model and MIC from our study, we predicted the rate of treatment success with amoxicillin treatment. Results: Sixty-three isolates were analyzed including 20.6% (n=13) of invasive isolates, and 79.4% (n=50) of non-invasive isolates; median age were 3.3 years old, and 87.3% of the pneumococcal infections occurred to children with underlying disease. Overall susceptibility rate was 49.2%, 68.2%, and 74.6% for amoxicillin, parenteral penicillin, and cefotaxime respectively. 23.8% and 9.5% of the isolates showed high resistance for amoxicillin, and cefotaxime. Only 4.8% (n=3) were susceptible to erythromycin. Monte Carlo simulation model revealed the likelihood of treatment success was 46.0% at the dosage of 90 mg/kg/day of amoxicillin. Conclusions: Recent pneumococcal isolates from pediatric patients with underlying disease revealed high resistance for amoxicillin and cefotaxime, and high resistance for erythromycin. Prudent choice of antibiotics based on the local data of resistance cannot be emphasized enough, especially in high risk patients with underlying disease, and timely vaccination should be implemented for prevention of the spread of resistant strains.
