  • The bone formation accompanied with other diseases in brain has been rarely reported. Furthermore, it has not been reported without any specific disease. We report a case of a 27 year old female who was referred to our hospital because of the incidentally found calcified lesion in plain X-ray of the skull. The CT and MRI of the brain showed a calcification with minimal enhancement at left parietal area. The calcified lesion was removed and biopsy was performed with stereotactic guided craniotomy. Pathologically, the lesion was confirmed as the membranous bone which was composed of bony trabeculations with osteocytes and the biopsy from adjacent area to the bone revealed a gliosis without any other disease.

  • MOVC is an uncommon disease which can be corrected by surgical method if early detected. A case of a 34-year-old male with MOVC is reported. Operation was done on cardiopulmonary bypass with circulatory arrest under moderate hypothermia. The incision was done both on the RA extending to level of suprahepatic IVC and on the IVC just proximal to the right renal vein. And then, thrombectomy and membranectomy under the direct visualization was done. Total circulatory arrest was used intermittently in order to get good visual field and for preventing blood loss. The Postop. course was good except one episode of hepatic encephalopathy which was persisted for 12 hours and then controlled by conservative measures.

  • Congenital diaphragmatic eventration is a rare disease and generally accepted as an abnormally high position of part or all of the diaphragm, usually associated with a marked decrease in muscle fibers and a membranous appearance of the abnormal area. There were 4 cases of the congenital diaphragmatic eventration at the Dept. of Thoracic Surgery, Seoul National University Hospital, from 1957 to 1977. They were two boys and two girls and ranging from 1 day to 3 years of age. They were all repaired by surgical operation and one was expired postoperatively, another one was dead one year later due to complication. The ratio between right and left was 1:3 and their symptoms were cyanosis, dyspnea and frequent respiratory disease. In physical examination there was noted decreased breathing sound on the affected lung field and bowel sound was audible in some cases. Diagnosis was done by Chest X-ray and plication of the affected diaphragm was usually done in operation. There were noted atelectasis and cystic change of the affected side lung. And the liver, colon, spleen and small intestine were found in the dome of the eventrated diaphragm.

  • Three new species of Hemicyclops, H. parilis, H. nasutus and H. membranatus are described from Korean coasts. Hemicyclops parilis n. sp. is closely similar to H. gomsoensis Ho and Kim, but distinguishable from the latter species by having the different shape of genital double somite and spermatophore. Hemicyclops nasutus n. sp. is distinguishable from congeners by having five setae on the first segment of antennule and the ratio 4.26 : 1 of the length to width of caudal ramus. Hemicyclops membranatus n. sp. is characterized by the possession of the membranous fringe along margins of cephalothorax and a claw on the third antennal segment.

  • A halacarid species of Scaptognathus teuriensis $Ab{\acute{e}}$ is recorded from Korea on the basis of the specimens collected from littoral sandy sediments at Dokdo Island, the easternmost island off Uleung Island of South Korea. Korean specimens coincide well with the key characters in the original description for types from Hokkaido, Japan, such as male genitoanal plate comprising only pars sclerosum, bipartite female genitoanal plate with six perigenital setae, rounded posterior margin of anterior dorsal plate, second and fifth dorsal setae both positioned at membranous cuticle, leg chaetotaxy of bipectinate setae on tibiae I-IV of 4-2-2-2, and tarsi of all legs armed with paired large lateral claws with accessary teeth and small median claw. Redescription based on Korean specimens and scanning electron microscope photomicrographs are provided herein. This is the first record of the genus from Korea.

  • Three specimens of Moolgarda seheli were collected for the first time from the southern coastal waters of Jeju Island in October 2010. This species is characterized by scales with a flexible membranous edge, a distinctive dark dot on the upper axis of the pectoral fin base, 39 lateral line scales, and 24~25 vertebrae. The newly proposed Korean name of the genus Moolgarda is "Cho-seung-kkori-sung-eo-sok" and that of M. seheli is "Cho-seung-kko-ri-sung-eo".

  • The red algal genus Amalthea was first described from New Zealand with one species, A. freemaniae. We discovered a new species of Amalthea from Korea, Amalthea rubida sp. nov., and described it based on morphology and rbcL sequences. A. rubida is characterized by a foliose, membranous and soft thallus having loosely arranged anticlinal medullary filaments, much like A. freemaniae, except for a difference of the cortex thickness in the basal part of vegetative structure. In the rbcL phylogenetic analyses, A. rubida formed a clade with A. freemaniae from New Zealand and Halymenia abyssicola from Mexico. A. rubida showed 5.7% interspecific divergence to A. freemaniae and 4.7% to H. abyssicola. Our discovery of A. rubida expands the distribution of Amalthea from the oceanic southwestern Pacific into the continental northwestern. A targeted global study is needed to fully reveal the species diversity and phylogenetic relationships of the genus Amalthea and members of the order Halymeniales.

  • Absorbers such as porous materials and panels have limited absorption characteristics to some frequency bands. There is a need for absorbers with high absorption coefficients in a wide frequency ranges to make good response of room acoustics. This is almost impossible for a single absorption material. Composite absorption structure with cover, porous material. and air gap is known to have those wide frequency characteristics. In this basis. various composite absorption structures are measured and investigated as wide range absorption structures. Measurements are performed according to an international standard, ISO 354. Various surface types such as wooden slits, wood/steel perforated panels are selected as surface covers, and also various porous materials such as polyurethanes, polyesters, and glasswools are used inside the covers. Result shows that the area of void parts of surface materials is critical to high frequency absorptions, and thickness of air gaps are critical factor of the peak absorptions of low frequency bands.

  • Three novel species, Philodromus daoxianen n. sp., P. ganxiensis n. sp., and P. longitibiacus n. sp., are described based on the specimens collected from Hunan Province, China. P. daoxianen is similar to P. rufus, but its spermathecae is calabash-shaped, that of the latter spherical. It is also similar to P. kendrabatai, but differs in the form of atrium, distance between two spermathecae and dorsal markings of the abdomen. P. ganxiensis differs from other species of the genus Philodromus in eplgynum by a pair of sword-shaped apophyses, palpal organ with slightly wider distal end of a tibial apophysis, and knife-shaped membranous median apophysis. P. longitibiacus differs from other related species in long and thin palps and legs especially tibia of palps, which is about 4.5 times as long as the cybium and basal portion of embolus strongly sclerotized.

  • Congenital esophageal stenosis (CES) can be classified into three types based on the etiology of stenosis: tracheobronchial remnants (TBRs), fibromuscular hypertrophy (FMH), and membranous diaphragm (MD). It is important to make a differential diagnosis because the therapeutic plan for CES is determined by its etiology. Most cases of FMH and MD can be managed with balloon dilatation, whereas cases of TBRs require resection and anastomosis. Thus, the preoperative distinction of TBRs is critical. Recently miniprobe endoscopic ultrasonography (EUS) with a maximum diameter of 2.5 mm has been useful for distinguishing TBRs from FMH in pediatric patients with CES. EUS shows hyperechoic lesions indicating TBR cartilage. Miniprobe EUS is recommended for choosing the correct therapeutic method for CES. We report a case of CES due to TBRs in which a preoperative diagnosis was made in a child using miniprobe EUS without any difficulties.
