  • A girl aged 18 years and 1 month, had a Angle's Class III malocclusion, characterized by .anterior crossbite, anterior crowding, and constriction from right lower 2nd premolar to right lower 2nd molar. This patient underwent sealing and (equation omitted) extraction, and multibanded system was placed. After 14 months, anterior crossbite and crowding was corrected, an bothdental arches were improved. After 6 months from debanding, band space disappeared and any relapse was not detected.

  • Environments of electric power industries are fastly changing due to the WTO, opening of the capital market and free trade. Accordingly, it is very important to invest in technical developments for securing international competitive power. But our construction techniques in T/L are insufficient in comparing with the advanced countries. This paper suggests the status and prospect of construction techniques of domestic and foreign countries in T/L, including developing prospects of T/L constriction.

  • For Percutaneous control of the degree of constriction after pulmonary artery banding, we developed an adjustable banding device that was operated by oil pressure. This consists of a stainless steel snare, a polyethylene tube with silicone oil, and a screw adjuster. Five dogs underwent banding of the pulmonary artery or the descending aorta with this device. This band could be effectively and finely adjusted. Although these studies are preliminary, they suggest that a reversible pulmonary artery band can be performed.

  • This paper attempts to qualitatively characterize scour erosion processes near USGS constriction type-I structures with vertical embankments and abutments. The scour dimensions and rates of sand beds around the structure models were measured in a rectangular flume. The test results showed that scour took place at a rapid rate at initial stages, which were followed by a stage of slow and general scour with greater extends. The maximum scour depth was observed near upstream corner of embankments. Empirical relationships for scour dimensions were derived, that were based on the results from a dimensional analysis of scour processes.

  • Effusive-constrictive pericarditis is a very rare disease in infants but has high motality rates when not treated. There were some reports of pericardial constriction associated with intrapericardial abscess that led to pericardiectomy. The patient was admitted due to fever, cyanosis, and abdominal distension. We treated the patient with antibiotics and pericardiostomy but the symtoms did not improved, therefore, pericardiectomy was perfomed immediately. The patient with effusive-constrictive pericarditis was immediately relief on the symptoms and the treatment was successful.

  • The speech of Sino-Korean has been evolved from geopolitical cause since 1945. The aim of this study is to collect Yanji dialectal speech and to compare with South Korean dialectal speech. Twenty Yanbian university students participated as informants. Acoustic speech informations are analyzed using the Multi-Speech Windows Vista version. Dialectal speech characteristics of Yanji sino-Korean showed posterior vowel /${\alpha}$/, neutralization of mid-vowel /o/ between /o/ and /Ɔ/. Lenis stop sound showed the tendency of glottalization based on VOT value. Sibilant sound contains aspiration following constriction and lateral /l/ realized the approximant /r/.

  • Lumbar foraminal pathology causing entrapment of neurovascular contents and radicular symptoms are commonly associated with foraminal stenosis. Foraminal neuropathy can also be derived from inflammation of the neighboring lateral recess or extraforaminal spaces. Conservative and interventional therapies have been used for the treatment of foraminal inflammation, fibrotic adhesion, and pain. This update reviews the anatomy, pathophysiology, clinical presentation, diagnosis, and current treatment options of foraminal neuropathy.
