With development of internet, location-based service (LBS) is getting more interest in wire and wireless network, and many studies are in progress to provide various services such as GIS and GPS technique related to this. Today positioning and information providing service is accomplished by mobile communication companies' chasing the cell or building unique GIS system, but there is a lot of building-cost that must be endured to define boundary of collecting precise location information from chasing Cell and provide unique location information service. In this paper, it desires to make the database of location information with using GPS, relatively precise satellite positioning system, to cut the cost of building location information service, and to present service models such as children's positioning service that is to reduce the cost of building GIS by using Web Open API and provide location information of discrete object in real-time.

Voiding cystourethrography (VCUG) is a commonly performed diagnostic procedure for the evaluation of vesicoureteral reflux with urinary tract infection or congenital renal diseases in children. The procedure is relatively simple and cost-effective, and complications are very rare. The iatrogenic complication of VCUG range from discomfort, urinary tract infection to bacteremia, as well as bladder rupture. Bladder rupture is a rare complication of VCUG, and only a few cases were reported. Bladder rupture among healthy children during VCUG is an especially uncommon event. Bladder rupture associated with VCUG is usually more common in chronically unused bladders like chronic renal failure. Presented is a case of bladder rupture that occurred during a VCUG in a healthy 9-month-old infant, due to instilled action of dye by high pressure. This injury completely healed after 7 days of operation, and it was confirmed with a postoperative cystography. The patient's bladder volume, underlying disease, velocity of the contrast media instilled, catheter size, and styles of instillation are important factors to prevent bladder rupture during VCUG. Management of bladder rupture should be individualized, but the majority of infants are treated with the operation. In conclusion, bladder rupture is a rare complication, however, delicate attention is needed in order to prevent more dire situations.

Objective: The purpose of this study is to examine the relationship between structural and process difficulties experienced by childcare center directors in operating childcare centers and to explore characteristics of childcare centers that affect the path. Methods: The participants were 309 childcare center directors, and data were collected through a mobile survey method. Descriptive statistics and SEM were implemented using SPSS and AMOS. Results: Unsupported childcare centers and capacity aggravated structural difficulties in operation of childcare centers, while the number of enrolled children and the enrollment rate reduced such difficulties that were reported by directors. In the case of labor cost supported centers and childcare centers with a high enrollment rate reported a high level of process difficulties. Because the effect of structural difficulties on process difficulties were significant, the indirect influences of structural difficulties that mediated the influences of general background characteristics on process difficulties were also significant. Conclusion/Implications: This study shows that difficulties in operating childcare centers could be considered in terms of structure and process aspects. This study is also meaningful in that it suggests that the characteristics of individual childcare centers should be emphasized in a customized way to alleviate such difficulties.

E-Card Service for Child Nutrition Program is one of the main public policy services nowadays. In case of inconvenience during the use of the e-cards, it is recommended to cooperate with related organizations in order to promptly handle and provide guidance, and thoroughly manage child feeding service such as hygiene, nutrition and kindness etc. To do so, it is very important to provide food service that meets local actual conditions and children's needs in a cost effective manner for the underage who are worried about the poorly-fed by understanding the pattern of child feeding e-card service. Hence. this paper aims to investigate how child feeding e-card service efficiently provides meals according to the local situation and children's needs through big data analysis and to propose a method of identifying welfare conditions according to the purpose of service with actual application examples. The results suggest that, first of all, this study is able to judge appropriateness of public institution's policy in a timely and repetitive manner through non-standard data analysis such as Naver News and transaction data. Secondly, this paper proposes a multi-layered analysis framework, which performs online open data analysis to detect policy issues, visualizes retrieval and preprocessing of real data, and performs abnormal pattern recognition. These will be worthy of reference to other similar projects.

The purpose of this study was to evaluate the childcare support demonstration services and direct policy. The participants for the study were three childcare (IDOLBOMI), three parents who were provided with IDOLBOMI, two practitioners, and three professors related to IDOLBOMI. The data was collected by interview and a phone survey and analyzed qualitatively. The results and several suggestions were follows: First, IDOLBOMI loved to take care of children, felt proud of the job, and thought the work was worthy. The result can help future IDOLBOMI when they are recruited and trained; Second, IDOLBOMI wanted income security at least, which means that the basic activity fee for the IDOLBOMI should be compensated by government; Third, most of the parents who experienced the service were generally satisfied with that, but they wanted the quality of nutrition, hygiene and the quality of play to be developed for children. Therefore, the management of the center and maintenance of education are needed constantly for the IDOLBOMI system; Fourth, the parents who needed the service thought the cost of IDOLBOMI was expensive. Expenditure support should be sought for the parents; Finally, the group of professionals had difficulty in securing the quality of childcare support services. For the future, it is necessary to increase the educational budget, manpower resources, and PR budget for IDOLBOMI.

Respiratory syncytial virus (RSV) is a major cause of respiratory infection in children. Most of the pediatric population have RSV infection before the age of 2, and recurrent infections are common even within one season. Chronic lung disease, prematurity, along with congenital heart disease (CHD) are major risk factors in severe lower respiratory infection. In hemo-dynamically significant CHD patients with RSV infection, hospitalization is usually needed and the possibility of treatment in intensive care unit and the use of mechanical ventilator support are known to increase. Therefore the prevention of RSV infection in CHD patients is mandatory. The current standard for RSV prevention is immunoprophylaxis by palivizumab. Immunoprophylaxis is recommended monthly in hemodynamically significant CHD patients, up to 5 months. Motabizumab, a second generation drug and newly developing RSV vaccines are also expected to play a key role in RSV prevention in the future. The prophylaxis of RSV infection in CHD patients is cost-effective in both the medical aspect of the patients as well as the socio-economic aspect. Therefore an effort to promote prevention should be made by not only the family of the patients but also by the government.

School facilities maintenance is concerned about providing clean and safe environments for children. It is also about creating a physical setting that is appropriate and adequate for learning. But many of the school buildings in Korea have been maintained and operated by each school manger or pubic officers in the Educational Department. This system could not extend the life of building components, keep equipment functioning as designed or sustain a sage and healthful environment because of its non-professionality and the dual fiscal system. In order to improve such problems, it is proposed to privatize the maintenance of school building. It is sure that the new way to outsource services reduce costs and provide high quality services. Competitive contracting with the private sector can provide schools with expertise, flexibility and cost efficiencies as well as help school administrators focusing on educating the children. This study explores the maintaining status of existing schools, analyses the cases about BTL schools and the foreign country's policies and surveys the outsourcing cases of Kyungki-do schools. Finally it proposes more appropriate plans for privatizing the maintenance way of school building in Korea.

We propose a multi-proportions randomized response model by stratified simple random sampling for surveys of sensitive issues of a polychotomous population composed of several stratum. We also systemize a theoretical validity to apply multi-proportions randomized response model (Abul-Ela et al.' model, Eriksson's model) to stratified simple random sampling and derive the estimate and its dispersion matrix of the proportion of sensitive characteristic of population using the suggested model. Two types of sample allocations (proportional allocation and optimum allocation) are considered under the fixed cost. In efficiency, the Eriksson's model by stratified sampling are compared to the Abul-Ela et al.' model.

This study was conducted to evaluate the dietary quality of school-aged children from low-income families in comparison with those from higher income families. The socio-demographic and anthropometric data and one day 24-hour recall dietary intake data of 1,782 school-aged children were used for analysis from the data of 2001 National Health and Nutrition Survey. The children whose family had monthly household income 120% or lower than the 2001 Minimum Cost of Living were classified into Low Income Group (LIG), and the others were classified into Higher Income Group (HIG). The consumption levels of the food groups of the Korean Food Guide as well as the general nutritional status based on their weight and height, energy and nutrient intake were compared between LIG and HIG in elementary (n = 989), middle (n = 432), and high (n = 361) school-aged children, respectively. LIG tended to have lower weight, height, and BMI than HIG, but the difference was significant only in the weight and the BMI of the middle school-aged children. The energy intake of LIG didn't differ from that of HIG, but LIG consumed a higher percentage of energy from carbohydrate and a lower percentage of energy from fat than HIG. Some micronutrient intake was lower in LIG than HIG in case of the elementary and the middle school-aged children. The average numbers of servings of milk dairy products and fruits consumed by LIG were significantly lower than those consumed by HIG in the elementary and the middle school-aged children, and they were less than the respective recommended serving. The average number of servings of meat fish egg beans consumed by LIG was lower than that consumed by HIG in the middle and the high school-aged children, and it was also less than the recommended serving. The results suggested that the diet of children from low-income families should be intervened by strategies different from the other children in order to improve the consumption level of milk dairy products, fruits, and meat fish egg beans.

Background/Aims: Polyps greater than 30 mm are classified as "giants". Their endoscopic removal represents a technical challenge. The choice of the endoscopic removal technique is important because it provides a resection sample for precise histopathological staging. This is pivotal for diagnostic, prognostic, and management purposes. Methods: From a retrospective analysis, we obtained a sample of 38 giant polyps. Eighteen polypectomies were performed using the epinephrine volume reduction (EVR) method, nine polypectomies utilized endo-looping or clipping methods, and 11 patients underwent surgery. Results: We obtained en bloc resection with the EVR method in all cases; histology confirmed the correct indication for endoscopic resection in all cases. Moreover, no early or delayed complications were observed, and no patient required hospitalization. Using endo-looping or clipping methods, we observed advanced histology in 1/9 (11.1%) cases, while another patient (1/9, 11.1%) had delayed bleeding. Among patients who underwent surgery, 5/11 (45.5%) were deemed overtreated and three had post-surgical complications. Conclusions: We propose EVR as an alternative technique for giant polyp resection due to its safety, effectiveness, cost-efficiency, and the advantage of avoiding the need to postpone polypectomy to a later time. Further prospective studies might help improve this experience and enhance the technique.
