During the last 10 years 8 months, clinical observation has been done on 43 cases of cryptorchisms. 1. The cryptorchism has relatively high incidence rate among the anomalies of genitourinary tract(27.2%). 2. The age group, most frequently seen, was between 6 to 10 and the average age visited the hospital at the first time is 11.4 years. It means 4 to 6 years later than age for the adequate treatment required. 3. Atrophy of the seminiferous tubules, interstitial fibrosis and poor or absent spermatogenesis were noted on the 8 cases of cryptorchid biopsies. 4. Hormonal therapy(Puberogen) was done on 16 cases and 8 cases were responded. But there was no complete descent of testis through this hormonal therapy.

Geotextile tubes are water-permeable tubular structures made of woven polymeric polyester (PET) or polypropylene (PP) synthetic fibers hydraulically filled with dredged sand currently used as alternatives for embankment construction. In this paper, a large direct-shear test was performed on a soil sample with wooden block wrapped by geotextile to figure out shear property of soil-geotextile tube interface.

Fillers are very important resources for the production of paper products; this is because they improve the properties of paper and reduce production cost. However, the natural inorganic resources for the manufacture of fillers are limited, so a new resource should be developed for the stable use of fillers in paper mills. In this study, the possibility of using sepiolite in the paper industry was investigated. Sepiolite is a complex magnesium silicate that is present in fibrous, fine particulate, and solid forms. This material is widely used in many industries, but it has not been used in the paper industry. We obtained sepiolite powder and investigated its particle shape, particle size, and size distribution. The handsheets made of SwBKP and HwBKP were manufactured by adding sepiolite. The physical properties, including the bulk, tensile strength, stiffness, ISO brightness, and opacity of the handsheets, were measured to analyze the effect of sepiolite on paper quality compared to GCC and PCC.

Purpose: There is an increasing amount of evidence that S100B could function as a marker of brain damage. However, the cerebral specificity of S100B has been questioned, so the extracerebral sources of S100B have been paid attention. We performed this investigation to show serum S100B levels after extracranial fracture in patients without current head injury and without prior neurological disease. Methods: At the emergency department, we obtained the blood samples within 6 hours from trauma patients hospitalized with extracranial fractures. S100B levels were compared between one fracture and more than two fractures, and analyzed according to the presence of soft tissue damage. Results: Patients with one fracture and those with more than two fractures did not differ by age (mean, 54.70 vs. 47.03, p=0.130), and there was no significant difference in the male-to-female ratio(33:32 vs. 21:12, p=0.226). In patients with one fracture, the mean value of S-100B was 0.56 μg/L (95% CI: 0.35-0.77) whereas in those with more than two fractures, the corresponding value was 1.09 μg/L (95% CI: 0.46-1.7, p=0.048). The S100B level of patients with soft tissue damage(1.32±0.38) was higher than that of patients without soft tissue damage(0.81±0.21), whether one fracture or more than two fractures(p=0.049). Conclusion: We present here that S100B levels were raised in 77% of patients with extracranial fractures without cerebral injury who were hospitalized from the emergency room and that the presence of soft tissue damage contributed to the increased S100B rather than the size of the fractured bone size or the number of fracturest. Thus, this study suggests that soft tissue injury may be considered as an important extracerebral source of S100B. (J Korean Soc Traumatol 2009;22:123-7)
