The characteristics of roadbed are very important factors in the design of railways. Laboratory model tests were performed to investigate the effectiveness of geogrid placement in the subbase layers on reinforcement. Design parameters of reinforcement were determined through the laboratory model tests. The results indicated that geogrid reinforcement is increased the bearing capacity and reduced the settlement of railway foundation. The optimum length of geogrid reinforcement is about 4B. The effective depth of geogrid placement from the bottom of ballast is about 0.1B~0.2B depended on magnitude of applied load.

The construction of structures on soft ground includes many problems. Soft ground- treatment method is necessary to increase in the stability of the soil-structures. Now Geosynthetic reinforced soil method of many soft ground treatment methods is being used widely by the economical and simple method. And the usage is increasing. It has been proved reinforce effects of Geosynthetic as a result of the general study on embankment reinforced Geosynthetic. But It is necessary to study variously on each spot condition to apply for Geosynthetic at the several practical field. Also, It is noted to study of effective installation of Geosynthetic on ground condition as well as tensile strength. This study was performed to analyze the stability through Limit Equilibrium Method on embankment reinforced with Geosynthetic. The applied soil parameter described the usual field conditions by applying design parameter used usually at the field. In finally, the influence of Geosynthetic installation and slope angle appeared slightly, but the influence of the depth of soft Ground, Cohesion, and tensile strength of Geosynthetic appeared relatively highly in stability.

Background: The aim of this study was to investigate the clinical presentations, patterns of soft-tissue injuries, and outcomes of treatment of elbow dislocations in patients with preexisting cubitus varus. Methods: Four cases of elbow dislocation in patients with preexisting cubitus varus, which were treated at 3 residency training hospitals, were retrospectively reviewed. Soft-tissue injury patterns were investigated using magnetic resonance imaging (MRI). Clinical outcomes were assessed at an average of 50.8 months (range, 34–82 months) after treatment using the Mayo Elbow Performance Score (MEPS) and the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score. Results: The mean patient age was 49.5 years (range, 33–57 years). All patients had a posteromedial elbow dislocation, which was an indirect injury caused by a fall onto an outstretched hand. One patient had failed closed reduction; 3 others had redislocation or gross instability after closed reduction. Significant tears of the lateral collateral ligament complex and common extensor group were shown in MRI. All patients had surgical treatment including lateral complex repair only (n = 2), repair of both sides’ complexes (n = 1), and corrective osteotomy with lateral complex repair (n = 1). At the final follow-up, the mean MEPS was 92.5 ± 8.7 and the mean QuickDASH score was 4.5 ± 6.4. Conclusions: Elbow dislocation in patients with preexisting cubitus varus may present as posteromedial dislocation with acute instability. Surgical treatment of this injury led to acceptable clinical outcomes.

Granulomatous hypophysitis is a rare pituitary condition that commonly presents with enlargement of the pituitary gland. A 31-year-old woman was admitted to the hospital with a severe headache and bitemporal hemianopsia. Magnetic resonance imaging (MRI) showed an 18 × 10-mm sellar mass with suprasellar extension and compression of the optic chiasm. Interestingly, brain MRI had shown no abnormal finding 4 months previously. On hormonal examination, hypopituitarism with mild hyperprolactinemia was noted. The biopsy revealed granulomatous changes with multinucleated giant cells. We herein report this rare case and discuss the relevant literature.

A surface-attached silymarin-loaded solid dispersion with improved dissolution profile and enhanced oral bioavailability was formulated using silymarin, polyvinylpyrrolidone (PVP) and Tween 80 in water. In this solid dispersion, hydrophilic PVP was adhered onto the surface of crystalline drug rendering silymarin hydrophilic without changing its crystallinity. The drug solubility from the optimised solid dispersion prepared with silymarin/PVP/Tween 80 at the weight ratio of 5/2.5/2.5 increased by almost 650-fold compared to drug powder. The drug was physically and chemically stable in the solid dispersion for at least 6 months. Moreover, the solid dispersion enhanced the oral bioavailability of the drug in rats by almost 3-fold compared to the commercial product. The silymarin-loaded solid dispersion also exhibited advanced hepatoprotective bioactivity against CCl4-induced liver damage compared to silymarin or the commercial product. Thus, this silymarin-loaded solid dispersion would be useful for the enhancement of oral bioavailability and hepatoprotective activity of poorly water-soluble silymarin.

The selection of geogrid types for the use of reinforced rail roadbed is important in the design of railways. Also, the problem of the construction damage on the geogrid during construction is raised by the field engineers. Therefore, laboratory model tests were performed to investigate the efficiency of the bearing capacity and construction damage. As a result, it was found that the bearing capacity of the rigid geogrid reinforced railroad ballast shows 1.54 times higher than that of the flexible geogrid reinforced case. In addition, there were no noticeable damage during construction.

The general concept of reinforced roadbed in the high-speed railway is to cope with the soft ground for the bearing capacity and settlement of foundation soil. The cyclic plate load tests were performed to determine the behavior of reinforced ground with multiple layers of geogrid underlying by soft soil. Five series of test were conducted with varying the soil profile conditions including the ground level, type of soil, and the thickness of each soil layer. Based on these plate load tests, laboratory model tests under cyclic loading were conducted to know the effect of geogrid reinforcement in particular for the high-speed rail roadbed. The permanent settlement and the behavior of earth pressure in reinforced roadbed subjected to a combination of static and dynamic loading are presented.
