The DMSA scan is a useful radiologic study in diagnosis of morphologic and functional diseases of kidney. We evaluated the distribution of sex and age, clinical manifestations, diagnosis, combined diseases, treatment and prognosis of the 61 patients with non-functioning kidney(no isotope uptake or uptake below 5% in DMSA scan) who admitted in our hospital from 1980 to 1995. The proportion of patients under 1 year old age was 46%. Sex ratio was 1.4:1 with male predominance. Most diagnosis of non-functioning kidneys were congenital such as multicystic dysplastic kidney, hydronephrosis due to ureteropelvic junction obstruction, renal agenesis and renal hypoplasia. In order of frequency thirty one percent of them were previously detected on antenatal ultrasonogram. Treatment consisted of operation in 47.5%, mostly nephrectomy and 32.8% of patients were followed up at OPD base without definite treatment. The most common combined diseases was hydronephrosis, in 4patients who had both kidneys inveloved progressed to chronic renal failure, but the prognosis in most cases were good. It is important to evaluate renal diseases in perinatal periods, and we believe that highly sensitive diagnostic study contribute to early treatment plan and thus to good prognosis.

Purpose: We previously reported that concurrent reactivation of latent Epstein-Barr virus (EBV) in children with hepatitis A virus (HAV) infection is common and EBV reactivation with HAV infection adversely affects the clinical features of hepatitis. However, the incidence of concurrent reactivation was not accurate because the detection of EBV reactivation was based on serologic methods. Therefore, we studied the effects of polymerase chain reaction (PCR)-proven EBV reactivation, thus a more precise concurrence, on acute HAV infection in children. Methods: PCR were conducted in 34 patients, who had enrolled previous study and diagnosed with acute HAV infection between January 2008 and June 2010. Their medical records were reviewed. Results: Among 34 patients with acute HAV infection, 12 patients (35.3%) had EBV reactivation which was proven using serologic and molecular biologic techniques. There were significant differences in the peak levels of AST and ALT between the reactivated and non-reactivated groups (p=0.001 and p<0.001, respectively). The duration of full recovery from hepatitis was more prolonged in the reactivated group (p<0.001). Clinical parameters, such as serum protein (p<0.001) and albumin concentrations (p<0.001), atypical lymphocyte count (p=0.001), prothrombin time-international normalized ratio (PT-INR, p<0.001), and splenomegaly (p<0.001), showed significant differences. The clinical features in the reactivated sub-group >10 years of age revealed more liver dysfunction compared to the non-reactivated sub-group. A comparison with a previous study was performed. Conclusion: PCR-proven reactivation of latent EBV in children with HAV infection is common and EBV reactivation with HAV infection adversely affects the clinical features of hepatitis, especially in older children.

The purpose of this study is to examine the importance of family environment for middle school student's health behavior. In order to do this we collected data through the questioning of 543 male students and 512 female students in 4 Pusan middle schools. The results of this study are summarized as follows. The score on their family cohesion and adaptability was 57.8, 43.5 on the average for male students and 59.8, 44.8 in female students. The score on their family adaptability and cohesion was higher in fema1e students than male students. The score of their Breslow health behavior was 4.20 from a total of 7.00, the total score of health behavior was 131.4 from a total of 176.0 scores. The students had a 43.9 out of 60.0 in personal hygiene and daily habits, 32.8 out of 40.0 for infectious disease preventive behavior, 30.2 out of 40.0 in accident prevention, 24.5 out of 36.0 in mental health. In the cases of males, the score for Breslow health behavior was higher the lower the school grade, the younger the parents, the higher the educational level of parents, the more comfortable the family, and the higher the economic state. There was a statistically significant difference with regard to family cohesion and adaptability. In the cases of females, The total score for health behavior was higher. However, the difference was not significant in other fields. With the multiple regression analysis, the health behavior of middle school student was associated significantly with sex (female students), grade, family cohesion, and adaptability. In Breslow health behavior, scale sex (male students), father's age, family cohesion and the harmony of parents were significant variables. From the results of this study, a good family environment fur middle school students is very important.

Purpose: The purpose of this study was to assess the hard and soft tissue changes associated with mandibular bilateral sagittal split osteotomy and genioplasty. Methods: This is a retrospective study of 40 patients who underwent either bilateral sagittal split osteotomy for mandibular setback (BSSO group, n = 20) or in combination with advancement genioplasty (Genio group, n = 20). Lateral radiographs, were taken before and immediately after surgery, and at least 6 months after surgery. Results: Comparing hard and soft tissue changes between the BSSO group and Genio group, there were significant differences in the lower incisor, soft tissue B point (B'), and soft tissue Pogonion (Pg') (p < 0.5). The mean ratio of hard and soft tissue changes for B/B', Pg/Pg', and Menton/soft tissue Menton after surgery in the BSSO group was 0.997, 0.965, and 1.022 respectively, and 0.824, 0.602, and 0.887 respectively in the genio group. Significant differences were found between the two groups. There were significant differences in lip thickness (B-B', Pg-Pg') in the Genioplasty group between pre and postsurgery, but not in the BSSO group. Pogonion to Labrale inferior and B' had a correlation coefficient of 0.833, 0.922, respectively for the BSSO group, and 0.775, 0.799 for the Genio group. Conclusions: The results indicate that there is a significant difference between bilateral sagittal split osteotomy with or without genioplasty in the lower facial esthetics values. The combination of mandibular setback and genioplasty had a smaller change in soft tissue thickness of the symphysis area after surgery than that of mandibular setback only.

Purpose: The purpose of this study was to examine the prevalence of food insecurity in Korean elderly and to analyze the health status as well as food and nutrient intakes according to food insecurity status. Methods: A total of 939 elderly subjects (over 65 years old) were used in our analysis from the fifth 2010 Korean National Health and Nutrition Examination Survey (KNHANES V-1). The variables consisted of general characteristics, physical and mental health, nutrient intake, rate of deficient intake of energy and nutrients compared with Dietary Reference Intakes for Koreans (KDRIs) and food quality and diversity according to the status of food insecurity. Food insecurity status was measured using a self-reported food security questionnaire on the dietary situation in the previous year, and participants were classified according to three groups: food secure group, mildly food insecure group, and moderately/severely food insecure group. Results: The proportion of the food insecure group was approximately 67% and the food insecure group had lower income and educational status than the food secure group. Food insecurity was associated with worse physical and mental health status after adjusting potentially confounding variables. The results showed that food insecurity in Korean elderly significantly affected mental health (including stress cognition, depression experience, and suicide thoughts) which exceeded stages of physical health. In addition, food insecurity showed significant association with low nutrient intake and high rate of deficient intakes of energy and nutrients compared with KDRIs, and a reduction of dietary quality and diversity was indicated in the food insecure group. Conclusion: This study concludes that the prevalence of food insecurity may affect the physical and mental health as well as dietary intake of the elderly Korean population. Therefore, food insecurity should be considered as an important public health issue in Korea.

This study was conducted to investigate optimum planting density for apartment complex. The validity of Landscape Architecture Criteria of Korea was checked for it. We compared our field data with Landscape Architecture Criteria. In this step, the tree density of urban forest was regarded as standard. Field study was examined in 3 apartment complexes located in capital area, especially completed during these 10 years. 10 sites in each complex were selected and tree density per unit area were calculated. This field study data was divided standard size and large size which received weight. And, it was compared and analyzed. And crown projected area(CPA) was calculated considering proper growth of low vegetation and sufficient shade. The outcome shows that minimum size of Landscape Architecture Criteria is rational. But, in the case of planting large size tree received weight, tree density was short comparing with the tree density of urban forest and CPA was less than 50%. By the result of field study in 3 apartment complex, the tree density of apartment complex satisfied or exceeded Landscape Architecture Criteria. But, in the case of planting large size tree, tree density and CPA show high density due to addition planting for deficient landscape. Therefore, the revision of the Landscape Architecture Criteria was required such as deletion or minimization of the weighted clause about the large size tree and regulate the limit CPA not less than 50% and not more than 100%.

This study attempted to develop a model for selecting sites for ecologically effective, multi-functional wetlands during the environmental and ecological planning stage, prior to land use Planning. This model was developed with an emphasis upon the creation of a water circulation system for a newly-created city, dispersing and retaining the run-off that is increased due to urbanization and securing spaces to create wetlands that can promote urban biodiversity. A series of Precesses for selecting sites for wetland restoration and creation - watershed analysis, selection of evaluation items, calculation of weights, reparation of thematic maps and synthesis - were incorporated into the model. Its potentials and limitations were examined by applying it to the recently-planned WiRae New Community Development Area, which is located in the Seoul metropolitan region. At the watershed analysis stage, the site was divided into 13 sub-catchment areas. Inflow to watersheds including the area was $3,020,765m^3$ Run-off before and after development is estimated as $1,901,969m^3$ and $1,970,735{\sim}2,039,502m^3$, respectively. The total storage capacity required in the development area amounts to $68,766{\sim}137,533m^3$. When thematic maps were overlapped during the selection stage for wetland sites, 13 sub-catchment areas were prioritized for wetland restoration and creation. The locations and areas for retaining run-off showed that various types of wetlands, including retaining wetlands (area wetlands), riverine wetlands (linear wetlands) and pond wetlands (point wetlands), can be created and that they can be systematically connected. By providing a basic framework for the water circulation system plan of an entire city, it may be used effectively in the space planning stage, such as planning an urban eco-network through integration with greet areas. In order to estimate reasonable run-off and create an adequate water circulation system however, a feedback process following land use planning is required. This study strived to promote urban changes in a positive direction while minimizing urban changes in negative forms.
