Purpose : Efforts to predict long-term outcome of focal segmental glomerulosclerosis(FSCS) have been made but have yielded conflicting results. Reports are rare especially in Pediatric patients. In this study, we reviewed the predictable prognostic factors in patients of FSGS Method : Fifty children who diagnosed as biopsy-proven FSGS at department of pediatrics at Yonsei university were studied retrospectively. Based on medical records, response to treatment and pathologic slides, we compared normal renal function group and decreased renal function group, assessed the factors affecting renal survival and progression to renal failure. Results : The mean age at onset was 8 1/12 years, sex ratio was 2.3 : 1, and the mean duration of follow-up was 7 1/12 years. The overall renal survival rate was $34\%$ at 5 years, $8\%$ at 10 years Five-year survival rate was $74\%$ in normal renal function group and $27\%$ in decreased renal function group. Between the two groups, there were no significant differences in age at onset, sex ratio, amount of proteinuria, incidence of hematuria and hypertension, mesangial hypercellularity. Decreased renal function group showed higher serum creatinine level, poor response to treatment, higher percent of glomeruli with sclerosis, moderate to severe tubulointerstitial change and vascular change(P<0.05). The prognostic factors of renal survival rate were same as above and incidence of hypertension also affected renal survival( P<0.05). The progression rate to renal failure did not show statistically significant factor. Conclusion : We reviewed the factors affecting long-term outcome of FSGS. Serum creatinine level, steroid responsiveness, and the degree of glomerulosclerosis were significant prognostic factors. (J Korean Soc Pediatr Nephrol 2001 ;5 : 125-35)

This study is a qualitative study using phenomenological methods that focus on the meaning of what individuals experience to understand the meaning of the gender role of women after childbirth. The participants of this study are 17 women who gave a birth from 8 weeks of the postpartum period to a year after the birth. Seven categories were derived from the results of analyzing the meaning of the gender roles of participants, and the seven categories are confirmed to be body changes and pain, just making me feel down, the difference between expectation and reality, isolation from husband and social network, thinking about my mother as a woman, the pain of body and mind sublimates, and convergence/dissociation between femininity and motherhood. This study is meaningful in that the results of this study provided information that would have a broader understanding of women's gender role after giving birth.

The development of social platforms and digital technology has promoted the age of the communication in our society. As online communication has become commonplace, expressing feelings, thoughts and experiences on the Internet has become an everyday routine. Among them, SNS is one of the representative platforms for expressing oneself easily and interacting with other users. The way of communicating with the SNS about what they did and what experiences they experienced from one's everyday lives became more common. As a result, the museum makes various efforts to enhance visitors' attention and interest with the use of SNS. It provides a content-based programs and museum environment that allow visitors to enjoy playing and learning at the same time. This study will explore not only a simple appreciation, but also the way of communicating to everyday life in terms of the changes for museum environment through the development, implementation and adaptations of digital technology. Through this, mobile-based communication with SNS provides various values and quality of museum visit, can be completed with meaningful museum experience, and various roles and functions of the museum are examined in terms of social platform of experience.

This study selected 3D printing that is highly likely to be adopted in schools. This research was conducted in two stages: 1) proposing the learning activity framework for utilizing 3D printing in education, and 2) exploring the potential of integrating 3D printing in the school field. The '3D printing learning activity framework' proposed in this study includes four phases that are categorized according to the complexity of problem-solving processes and collaborative interaction: Step 1 as production through replication, Phase 2 as means of imaginary expression, Phase 3 as near problem-solving, and Phase 4 as expanded problem-solving. Next, we conducted the field study with 23 students in the 6th grade math class where they learned the various solid shapes and volumes through 3D printing-integrated activities. The lesson was considered as Phase 1, which is the production through replication. Overall, the results showed that the participants had positive perceptions about the efficacy of 3D printing activities, the quality of learning experience, and satisfaction. On the other hand, it was found that the usability of 3D printers and CAD program needs further improvement The contribution of this study can be found in the learning activity framework that can guide 3D printing activity design in school, and in the exploration of enhancing the connection between 3D printing activities and curricular relevance beyond simple interest toward a novel technology.

Juvenile rheumatoid arthritis(JRA) is the most common major connective tissue disease in children. Renal involvement in JRA is rare. Among the renal lesions that have been reported in JRA, amyloidosis and drug-induced nephropathy are the most common. Crescentic glomerulonephritis in JRA has rarely been reported. We report a case of ANCA-associated pauci-immune crescentic glomerulonephritis in JRA. The patient was a 15-year old boy with a 3-year history of JRA. He presented with gross hematuria, proteinuria, positive p-ANCA and elevation of BUN and creatinine. Pathologic findings revealed focal necrotizing and crescentic glomerulonephritis. There were no significant immunoglobulin or complement deposits. His renal function recovered after intravenous methylprednisolone pulse therapy and oral steroid use. In Korea, this is the first reported case of pauci-immune crescentic glomerulonephritis in JRA. (J Korean Soc Pediatr Nephrol 2005;9:231-236)

The construction of the first nuclear power plant (Kori #1) in Korea started in 1971, Korea operates 24 nuclear power plants and is constructing 4 in 2015. During about 45 years of construction experience, insufficient studies have been investigated for the identification of critical success factors(CSFs) for nuclear power plant construction. Based on literature reviews and focus group interviews, this study presented a list of CSFs for construction of nuclear power plants. A survey for validating the results of CSFs was conducted with 164 experts. This study indicates that attentions should be placed upon the lowest price-based contract awarding policy, the need for reasonable pricing standard implementation, database development, and deployment for experienced nuclear power plant construction workers, identification and nurturing of competitive subcontractors, and minimization of lag times in construction activities.
