Acute torsion of the ovary and ovarian mass is a recognized surgical emergency, but rarely has the diagnosis been made preoperatively on the basis of imaging studies. The sonographic findings in 14 cases of surgically proven torsion of the ovary and ovarian mass are described. Mostly cystic ovarian mass, engorged vessel, dilated uterine tube, beak-like echo(torsion site), smooth mass wall thickening an free-fluid collection in cul-de-sac are described. More significant in terms of specificity were the demonstration in 6 cases(42.9%) of the smooth mass wall thickening and in 8 cases(57.1%) of a free fluid in the cul-de-sac. We report the sonographic findings of ovary and ovarian mass torsion that may suggest the preoperative diagnosis of this condition.

Friction welding has many merits such as energy efficiency, simple processing, etc. but it is difficult to obtain good welding at the welded interfaces and heat affected zone. It is discovered that stress singularity exists at the interfaces and heat affected zone. The computer program based on boundary element method is utilized in this study. A mathematical model is implemented based on results from several experiments performed at and around the welded interfaces and heat affected zone of disimilar metal under static and dynamic loadings. This study is to investigate the characteristics of the deformation and fracture behavior around interfaces for friction welded materials under static tensile load. Also, the stress distribution at the tip of crack is analyzed by using BEM based on Kelvin's solution of 2-dimensional binding zone. The results of BEM are identical with those in case of considering interfaces of both heat affected zone. Also, stress singularity at the tip of interfaces appears when the elastic modulus ration is 1.07.

Mediastinum is the space located between the right and left lung in the center of the thorax, and contains many vital organs such as heart, aorta, esophagus, vagus nerve, lymphatics. So the infection of mediastinal space cause a serious and potentially fatal process. Like other infections, surgical drainage, aggressive antibiotic therpy and supporative care are recommended for optimal outcome. Airway management in the presence of the neck, glottic edema, elevation of the tongue is a formidible problem especially in the case from odontogenic origin. We have rcently experienced such a case resulting in a number of local and systemic complications.

To use the earth heat, an underground heat exchanger is developed and pipes are layed in the depth of 2.5m under the ground. The pipes have two different kinds of diameter (200mm,100mm) and materials(PE, PVC). The results of cooling effect in summer and in fall are following. The temperature in different soil depth varies from 22.7℃ by 1.5m depth, 20℃ by 2.5m to 15℃ by 3.5m. So it should be better to have the depth greater than 2.5m. The difference of air temperature between the inside and outside pipe was 7Kelvin(K) with 200mm diameter and 17K with the 100mm diameter with the same material in summer. By the higher outside temperature from 36℃, it could keep the air temperature below 20℃ inside the pipe. The cooling performance was 1,992W with 200mm diameter (PE), 1,375W with 100mm diameter (PE), and 1,196W with 100mm diameter(PVC), respectively. As the outside temperature varies from 28℃to 5℃ in autumn, the temperature under the ground shows 17.5~15℃. The difference between maximum and minimum temperature are 12K with 200mm diameter (PE), 8K with the 100mm diameter(PVC) and 7K pipe with 100mm diameter(PE). Pipes with small diameter can more reduce the difference than the pipe with larger diameter.

Comparison of four species (Prunus yedoensis, P. sargentii, P. pendula for. ascendens, P. serrulata var. quelpaertensis) and one cultivar of P. yedoensis were carried out by comparing their nucleotide sequences from the internal transcribed spacers (ITS) I of nuclear ribosomal DNA (rDNA). The length of the ITS I region was ranged from 229 to 236 base pairs (bp). The G+C contents of ITS I ranged from 58.5 to 60.2%. The value of nucleotide divergence across for four Prunus species and one cultivar ranged from 0.4 to 6%. The pairwise distance between P. pendula for. ascendens and P. yedoensis was 0.004 showing the lowest value among any other pairs. On the other hand, the pairwise distance betwen P. yedoensis and cultivated P. yedoensis was 0.026. The nucleotide analysis based on ITS I sequence was considerably similar to previous studies on the basis of random amplified polymorphic DNA (RAPD).

Frog atrial muscle preparations were used to investigate effects of acid-base disturbances on the resting membrane potential and action potential on a cellular basis. To record the action potential of atrial muscle cells, 3M KCL-filled glass microelectrodes were directly introduced into the muscle cells in acidic(pH 6.0) and alkali(pH 8.0) conditions which were induced by addition of HCl and NaOH respectively into media. The following results were obtained : 1. In acidic condition, the resting membrane potential hyperpolarized from -(80±4.1)mV(P<0.05) and the overshoot potential was decreased significantly from 26±2.4mV of the control to 18±1.7mV(p<0.001). The time needed to repolarize 90% of the action potential duration, (repol 90%) shortened from 460~560 msec of the control to 400~520 msec in acidic intervention. 2. Little effect on resting membrane potential and action potential amplitude was observed in the alkali condition but Repol 90% shortened from 420~520 msec of the control 380~460 msec. (p<0.001) above results may be interpreted as that hydrogen ion affects the surface charge density at atrial muscle cells in such a way to inhibit ionic currents, especially slow inward and delayed outward currents.
