Purpose : Ventriculoperitoneal (VP) shunt insertion is an important treatment modality in children with hydrocephalus. VP shunt infection is a major complication and an important factor that determines the surgery outcome. This 15-year study was performed to evaluate the epidemiology of VP shunt infections in pediatric patients treated at our center. Methods : A retrospective review of medical records was performed in patients 18 years old or younger who underwent VP shunt insertion surgery from April 1995 to June 2010. Results : Three hundred twenty-seven VP shunt surgeries were performed in a total of 190 pediatric patients (83 females, 107 males). The median age of the patients was 2.4 years (range, 0.02-17.9 years). Having a malignant brain tumor was the most frequent cause for VP shunt insertion. The shunt infection rate was 6.7% (22/327) per 100 operations and 9.5% (18/190) per 100 patients, and the incidence rate was 0.45 infection cases per 100 shunt operations-year. The most common pathogen was coagulase-negative staphylococcus (n=7) followed by methicillin resistant Staphylococcus aureus (n=1). Ten cases were treated with vancomycin and beta-lactam antibiotic (cephalosporin or carbapenem) combination therapy and 7 cases were treated with vancomycin monotherapy. The median duration of antibiotic treatment was 26 days (range, 7 to 58 days). Surgical intervention was performed in 18 cases (18/22, 81.8%). Conclusion : Epidemiologic information regarding VP shunt infections in pediatric patients is valuable that will help guide proper antibiotic management. Additional studies on the risk factors for developing VP shunt infections are also warranted.

Purpose: To test the effects of health education on the blood pressure, knowledge, and self-care of visiting nursing clients. Methods: The study subjects were 96 participants who had been diagnosed with hypertension or had high risk factors for hypertension among those registered at a public health center in Seoul. The education program was individualized and delivered to enhance the management of hypertension including life-style modification, medication, and complication managements. Data were collected using questionnaires from May to December 2006 and analyzed using descriptive analysis, t-test, paired t-test, and ANOVA. Results: The blood pressure of the participants after the education was significantly decreased compared to before the education. Education also significantly affected the increases of knowledge of the disease and self-care capability. However, the blood pressure and self care were not significantly improved for the age group over 85 years. Conclusions: This study proves that the individualized health education for visiting nursing clients was effective in improving blood pressure, knowledge, and self-care of hypertension. However, it is necessary to develop strategies that are specifically targeted at particular age groups in order to improve the capability of self-care of hypertension.

WSN has been utilized in various directions from basic infrastructure of environment composition to business models including corporate inventory, production and distribution management. However, as energy organizations' private information, which should be protected safely, has been integrated with ICT such as WSN to be informatization, it is placed at potential risk of leaking out with ease. Accordingly, it is time to need secure sensor node deployment strategies for stable enterprise business. Establishment of fragmentary security enhancement strategies without considering energy organizations' security status has a great effect on energy organizations' business sustainability in the event of a security accident. However, most of the existing security level evaluation models for diagnosing energy organizations' security use technology-centered measurement methods, and there are very insufficient studies on managerial and environmental factors. Therefore, this study would like to diagnose energy organizations' security and to look into how to accordingly establish strategies for planning secure sensor node deployment strategies.

Purpose: Matrix metalloproteinases (MMPs) have been implicated in atherosclerosis, and therefore, are considered risk factors for metabolic dysfunction in adults. However, there is little data on circulating levels of MMPs and tissue inhibitors of MMPs (TIMPs) with regard to obesity-related biomarkers in the general adolescent population. In the present study, we determined the associations of MMP-8, MMP-9, and TIMP-1 levels and MMP-8/TIMP-1 and MMP-9/TIMP-1 ratios with obesity-related biomarkers in apparently healthy adolescent boys. Methods: We measured MMP and TIMP concentrations in plasma samples using the enzyme-linked immunosorbent assay and analyzed their associations with obesity-related biomarkers, such as liver enzymes and lipid profiles, in a sample of 91 Korean boys aged 13-14 years who participated in a general health check-up. Results: The mean age of the boys was $13.8{\pm}0.3years$; 72 boys were normal weight and 19 were overweight/obese. The Pearson correlation coefficients revealed a significant correlation between MMP-8 and aspartate aminotransferase (r=0.217, P=0.039) and alanine aminotransferase (r=0.250, P=0.017) and between TIMP-1 and aspartate aminotransferase (r=0.267, P=0.011). In a multivariate linear regression analysis, serum alanine aminotransferase was positively associated with the MMP-8 level. There were no significant differences in the MMP-8, MMP-9, and TIMP-1 levels or MMP-8/TIMP-1 and MMP-9/TIMP-1 ratios between control and overweight/obese subjects. Conclusion: We found a significant association between the MMP-8 level and alanine aminotransferase in the apparently healthy adolescent boys. These findings indicate that there may be a pathophysiological mechanism underlying the relationship between MMP-8 and liver enzymes in young adolescents.

Objectives : Childhood depressive disorder one of the most prevalent chronic health conditions affecting school aged children. The objective of this study was to examine the prevalence and epidemiological characteristics of childhood depressive disorder in Korea. Methods : In this study, a survey was conducted of elementary school children in the Cheonan area from September 2009 to August 2010. A total of 12,084 children were included in the analyses. The primary measure of depression was the 27-item Kovacs' Children's Depression Inventory (CDI), the Korean Dupaul attention-deficit hyperactivity disorder Rating Scales (K-ARS), Autism Spectrum Screening Questionnaire (ASSQ) and Restless Legs Syndrome Questionnaire (RLSQ) were also administered. Results : The prevalence rate of childhood depressive disorder was 3.07%. The mean age was $9.21{\pm}1.81$ years for the control group (5,969 male, 6,054 female) and $9.91{\pm}1.83$ years for the depression group (CDI score${\geq}$22 ; 159 male, 210 female). Age, height, weight, and economic status were similar for the two groups. However, there were statistically significant differences in the distribution of sex. The distribution of school grade also differed between the two groups. Scores for CDI, K-ARS, and ASSQ in the depressive group were higher than those of the control group. Conclusions : This is the first large-scale population-based study to report on the prevalence of childhood depressive disorder in South Korea. Increased rates of childhood depressive disorder, as reported by primary caretakers, might reflect the increasing negative impact of environmental risk factors on neurobehavioral health. Longitudinal study of the prevalence of childhood depressive disorder should be considered for further evaluation.

The purpose of this study was to examine the association between oral health status and health related quality of life (HRQoL). The study used a nationally representative sample of Koreans (2013 Korea National Health and Nutrition Examination Survey) aged 19~64 years (n=3,252). Dependent variable was HRQoL, which was assessed with each component of EuroQol-5 dimension (EQ5D). Independent variable was oral health status (oral pain, chewing problem, speaking problem, and perceived oral health). After adjustment for confounders (socio-demographic factors, oral health behaviors, health behaviors, and physical conditions), the risk of having poor HRQoL was greater in adults with poor oral health status. The odds ratio (OR) of having pain/discomfort were 1.50 (95% confidence interval [CI], 1.22~1.86) for respondents with oral pain, 1.72 (95% CI, 1.33~ 2.22) for respondents with chewing problem, 1.79 (95% CI, 1.22~2.62) for respondents with speaking problem, and 1.36 (95% CI, 1.09~1.70) for respondents with poor perceived oral health. The OR of having anxiety/depression were 1.74 (95% CI, 1.28~2.38) when having a chewing problem, 1.72 (95% CI, 1.12~2.64) when having a speaking problem, and 1.54 (95% CI, 1.14~2.08) when rating his/her oral health poor. Among Korean adults, two of the EQ5D components were associated with oral health status. Future study is needed to examine the detailed causal relations between oral health status and HRQoL longitudinally.

Background: The aim of this study was to investigate the demographic and clinical characteristics of patients with primary frozen shoulder in a Korean population. Methods: A total of 1,373 patients whose shoulders were diagnosed with primary frozen shoulder across 11 resident-training hospitals were reviewed retrospectively. Various demographic characteristics and clinical characteristics according to gender and presence of diabetes were evaluated. Results: The average age of patients was 55.4 years. Gender proportion was 58.3% females and 41.7% males. The frozen shoulder involved the non-dominant arm in 60.7% of patients and the bilateral arms in 17.6% of patients. The average duration of symptoms was 8.9 months, and 51.3% of patients had experienced nocturnal pain. Comorbidities associated with frozen shoulder in our sample of patients included diabetes (18.7%), cardiovascular diseases (17.7%), thyroid diseases (5.4%), and cerebrovascular diseases (3.6%). The diabetic group was correlated with the following demographic and clinical characteristics: old age, involvement of the dominant arm, nocturnal pain, long duration of symptoms, and no history of trauma. Further, we found that, in males, having a frozen shoulder was significantly correlated with a history of trauma; in females, having a frozen shoulder was significantly correlated with having thyroid diseases. Conclusions: These demographic data of primary frozen shoulder in the Korean population were consistent with those of previously reported epidemiologic studies. Primary frozen shoulder with diabetes was correlated with old age, bilateral involvement, long duration of symptoms, and nocturnal pain.

Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

Colorectal cancer is one of the most common cancers. Due to demographic changes, it is predicted that the incidence of this cancer will increase. Variations of its incidence rate among geographical areas are due to various contributing factors. Since there have been a lack of studies on this topic in our country, the present assessment of spatial patterns of colorectal cancer incidence in Iran was performed. In this ecological study, the new cases of colon cancer were extracted from Cancer Registry Center report of the Health Deputy of Iran in 2009. The reported incidences of the disease were standardized on the basis of the World Health Organization population and the direct method. Then the data were inserted into the GIS software, and finally, using the analysis of hot spots (Getis-Ord Gi) high-risk areas were drawn. Provinces that are higher or lower than the national average (1.9 SD) were considered hot spots or cold spots, significant at the level of 0.05. A total of 6,210 cases of colorectal cancer were registered in Iran in 2009, of which 3,727 were in men and 2,783 in women (age-standardized rates of 11.3 and 10.9 per 100,000 population, respectively). The results showed that in central and northern Iran including Isfahan, Qom, Tehran, Qazvin and Mazandaran significant hot spots in men were present (p <0.05). In women also we have high incidence in northern and central states: Mazandaran province (p<0.01) and the province of Tehran (p<0.05) had higher incidences than the national average and were apparent as significant hot spots. Analysis of the spatial distribution of colorectal cancer showed significant differences between different areas pointing to the necessity for further epidemiological studies into the etiology and early detection.
