  • The previous vitamin assays in soft capsules have been performed only with capsule contents. Since some vitamins, however, could migrate into gelatin layer of the soft capsules, each vitamin of multivitamin soft capsules in the market was analyzed simultaneously in both capsule content and gelatin layer. The results showed that migrations of nicotinamide and pyridoxine hydrochloride into gelatin layer were pronounced, while those of other vitamins were negligible.

  • As the multidirection and posterior instabilities of the shoulder are not only uncommon but responds well to conservative treatment, the shoulder instabilities which requires surgical treatment are traumatic anterior type in most cases, Although various surgical procedures had been used in the past, Bankart procedure is the standard surgical method as a primary procedure in traumatic anterior instability, Nevertheless there has been changes in the techniques of Bankart procedure in order to minimize decrease of external rotation and effectively address capsular laxilty, Capsular shift might be needed if there remains excessive capsular laxity of the inferior capsule after repair of the Bankart lesion, Large bony Bankart lesion should be fixed if possible and severe glenoid rim erosion requires extracapsular bone block after repair of the capsule. Although a few surgical procedures are described for the management of Hill-Sachs lesion in special circumstances, Hill-Sachs lesion does not usually need to be addressed.

  • For the accurate calibrations of thermometers at low temperatures, triple points of oxygen and argon have been realized using sealed-type triple point cells. The triple points were realized with both adiabatic and continuous heating methods. The resistance of three capsule-type standard platinum resistance thermometers were measured at the triple points of oxygen, argon, mercury and water for the calibrations of these thermometers in the range from $-220^{\circ}C$ to $0.01^{\circ}C$. The extended uncertainty, with the coverage factor of 2, of the calibration in this range is smaller than 1 mK.

  • The biopolymer membrane could be formed using marine polysaccharides. Chiotsan and alginate were used for the formation of capsule membrane to mimic the fish eggs such as flying fish eggs and salmon eggs. The size of capsules ranging 1 to 5mm was prepared and the mechanical tests were performed to determine the mechanical similarities to natural fish eggs. The similar mechanical pattern between the synthetic capsules and natural eggs could be found. The controlling parameters for the strength of capsules were pH of the chitosan solution. This encapsulation technique can be broadly applied to medical, engineering as well as food areas.

  • This study was designed to seek information on the heat charging and discharging characteristics of a multi-capsule type LTES(Latent Heat of Fusion Thermal Energy Storage) system, and especially prediction equation of outlet water temperature from the system. During heat charging process, the water temperature in the LTES tank increased very slowly in comparison with a predicted one and was kept near the melting point of the PCM for about 25 minutes. During heat discharging process, the latent heat discharging period of the outlet water temperature became longer as the inlet water temperature became higher and/or mass flow rate became lower. The dimensionless temperature of the outlet water was predicted by linking three equations of ${\theta}=1.1Exp(-{\tau}/0.82)$, ${\theta}=-0.06{\tau}+0.3$, ${\theta}=0.8Exp(-{\tau}/1.4)$ ($r^2{\leq}0.88$) depending on discharging period regardless of mass flow rates on the case of the inlet water temperature at $21.5^{\circ}C$.

  • The freezing characteristics of two kinds of phase change materials (PCM) encapsulated in a spherical container were investigated with various cooling air temperatures and velocities. The super cooling and solidification time of PCM were highly affected by cooling air temperature and velocity. The experimental equations are derived to express total solidification time of the PCM in terms of Nusselt number and dimensionless temperature.

  • This study was performed to investigate the usefulness of the radiopaque material as a disintegration test of enteric coated capsules radiologically. The results obtained were as follows; 1. The times that the enteric coated capsules passed the pylorus(GI transition times) were the first 150 minute and the last 390 minutes. Therefore, the GI transition times largely differ from each animal and each enteric coated capsule. 2. The disintegration times of enteric coated capsules were similar in vitro test and in vitro test. 3. The disintegration test of enteric coated capsules using Barium sulfate, radiopaque material for the gastrointestinal track, was useful to check the time pass through the pylorus and the time enteric coated capsules were disintegration.

  • Deer hemal nodes were studied by gross anatomy and light microscopy. Hemal nodes were scattered in the periphery of thoracic and abdominal aortae, and spherical or avoid in shape. A hemal node consisted of a thin capsule and a hilum, and had numerous small subcapsular and deep sinuses distended by a great number of erythrocytes. Although a few lymphatic nodules and tissues were seen in the parenchyma, no typical cortex and medulla was defined. Blood vessels occurred, but lymph vessel was not observed in nodes. The parenchyma of the hemal node consisted of many erythrocytes and lymphocytes, and a few granulocytes, plasma cells megakaryocytes and macrophages. The stroma was composed of reticular cells and fibers. The capsule and trabecula was a collagenous connective tissue with smooth myofibers. The above findings suggest that the hemal nodes are involved in blood storage, blood filtration and immune reaction.

  • Red scabream, Pagrus major , is a valuable aquaculture species in Korea , but spontaneous eye abnormality occurred in cultured individuals . The incidence of eye abnormality was 4% in the group of cultured red scebream. The abnormality was characterized by unilateral and bilateral exophthalmos, opacity and lens pathology. Lense prolapse was found in two cases. Lenses in diseased fishes was considerably small in diameter and eyes were deformed as a whole. In the group of induced hybrid red scabream Pagrus major (♀) x black seabrearn Acanthopagrus schlegeli (♂), the incidence of eye abnormality wa~ the same 4%, but only opacity was registered. Opacity was also found in two of sixteen examined Wild-caught red seabrcam. Histopathological changes of lenses in cultured red seabreem included vecuolated cytoplasm of lens fibers, necrosis of fibers in central part of lens, folding and increase in thickness of lens capsule, and epithelial proliferation beneath the anterior lens capsule. In affected eyes no parasites or gas bubbles were found.
