This study focused on developing new diagnostic tool combining K-CESA of national level with right people of H university and validating the new diagnostic tool. For this study, K-CESA and core competencies in right people of H university are combined through the literature review, and test items are developed based on the preceding research. Our process included not only analysis of the test items that consist of 74 developed preliminary study items based on classical test theory and item response theory but also verification of construct validity and reliability. According to the above study result, final test items are made up of 48 items and the test was verified to suitability of the examination after verification of the test validity and reliability. Developed diagnostic tool based on the study can diagnose university students' core competencies as the part of the specialized university and make a connection the program after evaluating the individual level of core competencies. Ultimately, this diagnostic tool is available as a basic data for promising talent based on the University Vision

    Congenital Nephrogenic Diabetes Insipidus Presented with Bilateral Hydronephrosis: Genetic Analysis of V2R Gene Mutations

    Get PDF
    Most cases of hydronephrosis are caused by urinary tract obstruction. However, excessive polyuric syndrome rarely gives rise to non-obstructive hydronephrosis, megaureter, and a distended bladder. The authors report here on two cases of congenital nephrogenic diabetes insipidus (NDI) with severe bilateral hydronephrosis and megaureter. It is Interesting that the patients were symptomless except for their polyuria, and they both presented with bilateral hydronephrosis. Fluid deprivation testing revealed the presence of AVP resistant NDI. Gene analysis for these patients showed the AVP receptor 2 (V2R) missense mutations (Q225X and S126F), which have previously been reported on in other studies. We made the diagnosis of NDI by using a physiologic test, and we confirmed it by mutation analysis of the V2R gene.ope

[영문] Primary focal segmental glomerulosclerosis(FSGS) is common cause of nephrotic syndrome and is characterized by hematuria, hypertension, and progressive loss of renal function to renal failure. Although primary FSGS has been known to be refractory to treatment, recent studies reveal higher remission rate and better prognosis. And it has been reported that some clinical and histopathologic parameters such as heavy proteinuria and interstitial fibrosis were significant to prognosis. But, confirmative prognostic indices remain to be defined. In order to further clarify the prognostic factors to therapeutic response and risk factors for progression to CRF, we reviewed the medical records of adult patients diagnosed as FSGS by renal biopsy from 1991 to 2002 in Severance hospital. Following results were obtained. 1. The patients consisted of 24 male and 16 female, aged of 42Β±16(meanΒ±SD) years. 2. At the time of renal biopsy, 26 patients(65%) had proteinuria of the nephrotic range and 14 patients(35%) had proteinuria of the non-nephrotic range. The serum creatinine level was higher in nephrotic-ranged patients than that in non nephrotic-ranged patients(P<0.05). Age, sex, hypertension, microscopic hematuria, follow-up duration were not significantly different between two groups. 3. Twenty-seven patients were treated with immunosupressant and 15 patients(55.6%) responded to the treatment. There was no significant difference in clinical or histopathological variables between the patients with therapeutic response and the patients without response. 4. In the analysis of risk factors for progression to CRF, high serum creatinine level at diagnosis and responsiveness to treatment were identified as significant. 5. The patients treated with immunosuppressants had longer survival period compared to the patients without treatment, though the differences was not statistically significant. And, treatment responsive group had longer survival period compared to the non-responsive group significantly(P<0.05). In conclusion, the patient with initial impairment of renal function or poor response to therapy may have worse prognosis, and the intense treatment with regular follow-up of renal function should be recommended for these patients. Furthermore the prospective controlled study for the treatment of FSGS is required.ope

[영문]Background. Diabetic nephropathy is characterized by glomerular hypertrophy and ECM accumulation, and the p38 MAPK pathway is known to be activated in diabetic glomeruli, leading to an increase in fibronectin and type IV collagen expression. This study was undertaken to investigate the effect of a p38 MAPK inhibitor, FR167653, on urinary albumin excretion and on glomerular fibronectin and type IV collagen expression in diabetic rats.Methods. Thirty-two Sprague-Dawley rats were injected with diluent (C, N=16) or streptozotocin intraperitoneally (DM, N=16). Eight rats from each group were treated with 10 mg/kg/day FR167653 (C+FR, DM+FR) for 3 months. At the time of sacrifice, 24-hour urinary albumin excretion was determined by ELISA. Glomerular p38 MAPK and c-AMP-responsive element binding protein (CREB) activities were determined by Western blot with phospho-specific antibodies, and glomerular fibronectin and type IV collagen mRNA and protein expression were determined by real-time PCR and Western blot, respectively, with sieved glomeruli.Results. The ratio of kidney weight to body weight (KW/BW) in DM (1.54Β±0.13%) was significantly higher than that in C rats (0.53Β±0.04%; p<0.01), and the increase in KW/BW was ameliorated by FR167653 administration (0.84Β±0.07%; p<0.01). FR167653 also significantly inhibited the increase in albuminuria in DM rats (C, 0.40Β±0.06 mg/day; C+FR, 0.41Β±0.07; DM, 1.99Β±0.22 mg/day; DM+FR, 1.04Β±0.19 mg/day; p<0.05). Glomerular p38 MAPK and CREB activities were significantly increased in 3-month DM rats compared to C rats, and FR167653 significantly abrogated the increase in p38 MAPK and CREB activities in DM glomeruli (p<0.05). Fibronectin and type IV collagen mRNA expression were significantly increased in DM glomeruli and these increases were inhibited by 86.8% and 79.9%, respectively, with FR167653 treatment (p<0.05). FR167653 also ameliorated the increases in fibronectin and type IV collagen protein expression in DM glomeruli (p<0.05).Conclusions. These findings suggest that p38 MAPK could be a potential target for preventing nephropathy in diabetes.ope

    Background : Primary focal segmental glomerulosclerosis (FSGS) is a cause of nephrotic syndrome in adult. Although primary FSGS has been known to be refractory to treatment, recent studies reveal higher remission rate and better prognosis. And it has been reported that some clinical and histopathologic paramenters are significant to prognosis. But, confirmative prognostic indices remain to be defined. In order to further clarify the prognostic factors for therapeutic response and risk factors for progression to chronic renal failure (CRF), we reviewed the medical records of primary adult FSGS patients. Methods : Forty-adult patients diagnosed as primary FSGS between 1991 to 2002 were enrolled. We retrospectively analyzed the clinical and histopathological parameters of all patinents at the time of renal biopsy. In addition, the therapeutic responses to immunosuppressants and the renal survival were analyzed. Results : At the time of renal biopsy, 26 patients (65%) had proteinuria of the nephrotic range and 14 patients (35%) had proteinuria of the non-nephrotic range. The serum creatinine level was higher in nephrotic-ranged patients than that in non nephroticranged patients (p<0.05). The other parameters were not significantly different between two groups. Twenty-seven patients were treated with immunosuppressants and 15 patients (55.6%) responded to the treatment. There was no significant difference in clinical or histopathological variables between the responders and the non-responders. High serum creatinine level at diagnosis and responsiveness to treatment appeared to be significant as risk factors for progression to CRF (p<0.05). The paticnts treated with immunosuppressants had longer survival period, compared with those without treatment. And the responders had significantly longer survival period compared with the non-responders (p<0.05). Conclusion : The patients with initial impairment of renal function or poor response to therapy may have worse prognosis, and the intense treatment with regular follow-up of renal function should be recommended for these patients.ope
