Purpose: The location of renal cysts is related with the symptoms and signs. Parapelvic cysts are a rare form of simple renal cysts, and they are much more commonly associated with the symptoms of obstruction, pain, infection and stone formation. We evaluated the surgical outcomes of laparoscopic renal cyst marsupialization for treating the peripheral and parapelvic types of renal cysts. Materials and Methods: Between November 1993 and April 2007, 87 patients(91 cases) who presented with symptomatic renal cysts underwent laparoscopic renal cyst marsupialization. There were 76 cases in the peripheral cyst group and 15 cases in the parapelvic cyst group. The mean age was 59.2 years(age range: 20-77) for the patients with peripheral renal cysts and 62.9 years(age range: 47-79) for the patients with parapelvic cysts. Results: The mean operative time was 108 minutes(30-280) for the patients with peripheral renal cysts and 144 minutes(80-270) for the patients with parapelvic cysts, and there was a significant difference(p=0.031). However for the other factors, including the time for the first oral intake, the time to remove the drain and the length of the hospital stay, there were no significant differences(p=0.671, 0.088, 0.268, respectively). Complications, including bleeding and leakage, were detected in 11 patients(14.4%) of the peripheral cyst group and in 4 patients(26.6%) of the parapelvic cyst group; there was a statistical difference(p=0.035). Both groups had a high success rate, 98.7% in the peripheral cyst group and 100% in the parapelvic cyst group. Conclusions: We found that laparoscopic renal cyst marsupialization was a standard treatment with a high success rate and a fast recovery time. However, performing this for parapelvic cysts showed a longer operative time and a higher complication rate as compared with peripheral cysts.

Background: Osteoporosis is defined based on T-scores (<-2.5), which are calculated from mean value and standard deviation (SD) of bone mineral density (BMD) of young adults. Therefore the diagnosis of osteoporosis is race and population specific. We investigated new reference young population and establish the prevalence of osteoporosis. Methods: 3,435 males and 10,231 females are enrolled for this study, from 2003 to 2004. There BMD were taken at health promotion center, Ajou university hospital, Suwon, Korea by Dual energy X-ray Absorptiometry. Osteoporosis is defined by T-score less than -2.5 SD of 20~29 years old young adults in men. In women, T-score less than -2.5 SD of 30~39 years old adults. Results: In men, osteoporosis prevalence is twelve percent by previous reference value, but, eight percent by new reference value. In women, osteoporosis prevalence is twelve percent by previous reference value and eleven percent by new reference value. Conclusion: This result showed that different reference values leads to different prevalence of osteoporosis. So, for the accurate diagnosis of osteoporosis, reference populations of young adults depend on each machines should be representative of the population of each country.

Recently good quality river aggregate has decreased every year because of not only increasing of construction works but also problems due to protection against resources energy and nature. It is one method for problems, mentioned above to make use of slag a by-product of iron manufacture. This paper intend to study fundamental character of concrete experimentlly and to provide data for execution of work using slag concrete when silica manganic slag(Si Mn Slag) is used by the course aggregate for concrete.

The concrete used for road slab is well influenced by weather condition, especially by temperature, for the surface section made of concrete is larger than that of any other structure. When concrete repeat freezing and thawing by temperature condition, it is gradually in inferior quality by cracking and surface scaling phenomenon. So, when the concrete used for road slab is repeatedly, influenced by freezing and thawing, this phenomenon makes serious factor for the road slab durability. This paper is experimentally studied for the appearances that road slab concrete made of blastfurnace slag and natural gravel for maximum size aggregate, have repeatedly the condition of freezing and thawing.

Crossed testicular ectopia is a rare anomaly, in which both testes migrate toward the same hemiscrotum. Fewer than 100 cases of this condition have been reported in the literature worldwide. Occasionally, conditions initially suspected to be crossed testicular ectopia have proven to be other anomalies, including hypospadias, renal agenesis, and seminal vesicle cysts. In this case, we diagnosed ganglioneuroblastoma in a patient with testicular ectopia.
