Purpose: The purpose of this study was retrospectively to evaluate the results of the modified Kidner procedure for symptomatic accessory navicular in athletes. Materials and Methods: Between July 1999 and December 2004, 26 feet in 22 patients with symptomatic accessory navicular who had underwent modified Kidner procedure were available for clinical follow-up, and 12 cases in 9 patients were available for clinical and radiological follow-up with a minimum follow-up of 5 years were included in this study. All those patients had symptomatic accessory navicular bone who underwent modified Kidner procedure. American Orthopaedic Foot and Ankle Society (AOFAS) midfoot score, Visual Analogue Scale (VAS), and satisfaction rate were investigated. Talo-first metatarsal (T-MT1) angle, talo-calcaneal (TC) angle, and calcaneal pitch (CP) angle were measured in standing lateral radiograms. Results: AOFAS score was improved from $40.8{\pm}7.5$ (32~57) preoperatively to $88.7{\pm}8.0$ (72~100) postoperatively, and the difference was significant (p<0.01). VAS was improved from $7.0{\pm}0.9$ (5~9) preoperatively to $1.8{\pm}0.8$ (1~4) postoperatively, and the difference was significant (p<0.01). At the lastest follow up, 11 feet were very satisfied, 11 feet satisfied, and 4 feet unsatisfied (a satisfaction rate 85.0%). No significant difference was observed for T-MT1 angle (p=0.67), TC angle (p=0.93), and CP angle (p=0.49). Conclusion: Modified Kidner procedure for the symptomatic accessory navicular showed satisfactory results and is appeared to be one of the useful treatments.

Samples were obtained from broodstok in May, 2010, while naturally fertilized embryos were maintained, and the process of skeletal development was observed from larvae and juvenile. Prelarvae immediately after hatching showed an average total length of $6.85{\pm}0.63mm$ (n =5), Premaxillary and dentary were ossified, parasphenoid was ossified in the cranium, and centrum and caudal bone did not ossify. Prelarvae showed ossification with maxillary, articular, and epihyal, and branchiostegal rays of hyoid arch were ossified at 2 to 3 days after hatching with an average total length of $7.25{\pm}0.28mm$ (n=5). The vertebrae began to ossify in the direction of the tail, and neural spine began to ossify above the ossified vertebra. Postlarvae showed ossification of lateral ethmoid, alisphenoid, parietal, and caudal skeleton in the cranium when the average total length was $9.00{\pm}1.53mm$ (n=5) in 6 days after hatching. At 40 days after hatching, postlarvae ossified maxillary in the cranium, and ossified endopterygoid and ectopterygoid, etc. in the palate, when the average length of $23.3{\pm}0.28mm$ (n=5). At 120 days after hatching, with the average length was $37.5{\pm}2.83mm$ (n=5), caudal skeleton had one additional epural bone ossification, resulting in ossification of a total of 3 epural bone to complete ossification of all spicules.

편평족은 내측 세로궁이 소실되어 족저부가 편평하게 되는 변형의 총칭으로, 소아에서 흔하 고 보호자들의 관심이 많은 질환이다. 이학적 검사상 후족부의 외반과 전족부의 외전소견을 보이며, 감별질환을 위해 정확한 이학적 검사와 방사선학적 검사를 필요로 한다. 원인으로는 유연성 편평족, 종골 외반, 선천성 수직 거골, 부주상골, 족근골 결합등이 있으며 정상적 유 아의 경우 시간경과에 따라 저절로 호전되는 유연성 편평족이 대부분이다. 따라서 병적 편평족이 아닌 경우 편평족의 원인과 양호한 자연경과를 보호자에게 설명하는 것이 중요하다. 본 논문에서는 소아 편평족의 감별질환을 위한 각 질환에 있어서의 이학적 소견과 검사소견 그리고 이들의 치료에 대해 살펴 보고자 한다.

The whitespotted puffer, Arothron hispidus (Linnaeus, 1785), of the family Tetraodontidae were collected by an Koheung Peninsula in July 2003. This species is color of the body; covered with black and the spots on the body is white color. white. Dorsal fin rays 11~12; pectoral fin rays 17; anal fin rays 10~11; caudal fin rays 5+6=11; vertebrae 8+10=18. Measurement for five specimen (195.0~265.3 mm SL) in hundredths of standard length; head length 36.8%; pectoral fin length 13.4%; dorsal fin length 11.6%; caudal peduncle length 15.0%; caudal peduncle depth 13.7%. This is ventral postclavicle, exposed in hundredths of length 6.14~6.75; verterbrae 18; dorsal pterygiophores formula $7{\ast}1231$; number of dorsal pterygiophores 7.

Cause of flexible flat foot is predominantly idiopathic but pediatric flexible flatfoot is typically congenital. Neuromuscular disorders, tarsal coalition and prehallux are possible causes and there has been a controversy for diagnosis and surgical treatment guideline. Therefore we present 11-year old male with prehallux and flexible flat foot who was treated with Kidner procedure and subtalar arthroereisis using Kalix endoprothesis and reported good clinical outcome at 2-years follow up postoperatively.

Fertilized eggs of Takifugu pardalis (Temminck et Schlegel) were collected on the coast of Jook-do in Tongyong, Korea, from March 1997 to June 1999, and hatched and reared in the laboratory to investigate osteological development of the larve and juveniles. The newly hatched larvae attained a mean of $3.13{\pm}0.05mm$ in total length (TL). Ossification first began in the parasphenoid, premaxillary and dentary. At 5 days after hatching, the postlarvae attained a mean of $3.82{\pm}0.03mm$ in TL, and their sphenotic, prefrontal, preopercle, opercle, maxillary, and articular were ossified. At 15 days, the postlarvae attained a mean of $7.84{\pm}0.06mm$ in TL, their nasal and posttemporal bones were ossified and the hyoid arch completed ossification. Ossification of all bones was completed in the juveniles (mean = $10.21{\pm}0.06mm$ in TL) at 21 days.

Accessory navicular is a congenital anomaly of the tuberosity of the navicular from a secondary ossification center. The accessory navicular is occasionally the source of pain and local tenderness over the medial side of midfoot. If conservative treatment fails for the painful accessory navicular, surgical treatment is required. There are several surgical option for accessory navicular, which vary from simple excision, percutaneous drilling, modified Kidner procedure and osteosynthesis of the accessory ossicle to the navicular body. In addition, symptomatic flatfoot deformity should be addressed concomitantly.

The skeletal development of the larvae and juvenile of red marbled rockfish, Sebasticus tertius (Barsukov et Chen) was studied based on individuals that were discharged and reared in the laboratory from April to May 1997. In 8 days after bearing, the postlarvae attained 4.42 mm in total length (TL), and its parasphenoid, premaxillary, maxillary, and clavicle were ossified for the first time at this stage. In 15 days after bearing, the postlarvae attained 5.23 mm in TL, and its pterotic, basioccipital, exoccipital, opercle, and preopercle were ossified, with one spine on the each cranium and preopercle. In 27 days after bearing, the postlarvae attained 8.81 mm in TL, its vertebra were posteriorly ossified to the 15th centrum, and five spines were formed on the preopercle. In 39 days after bearing, the juveniles attained 14.21 mm in TL, and the all bones were almost completed at this stage.

The Hongseong area of the southwestern Gyeonggi massif is considered to be part of suture zone that is tectonically correlated with the Qinling-Dabie-Sulu belt of China in terms of the preservation of collisional evidences during Triassic in age. The Wolhyeonri complex, preserved at the center of the Hongseong area, consists mainly of Neoproterozoic orthogneisses and Middle Paleozoic intermediate- to high-grade metamorphic schists, orthogneisses and mafic metavolcanics. The area includes various Middle to Late Triassic intrusives (e.g. dyke or stock). They are mainly monzonite and aplite with small intrusions of monzodiorit, syenite and diorite in composition. The SHRIMP U-Pb zircon ages yield 237 Ma to 222 Ma. The geochemistry of the studied Triassic intrusives show similar subuction- or arc-type signatures having Ta-Nb troughs, depletion of P and Ti, and enrichment of LILEs (large ion lithophile elements). In addition, the Triassic plutons in the Hongseong area, including those from this study, mostly possess high-K calc-alkaline to shoshonitic tectonic affinity. These results could be tectonically correlated to the post-collisional magmatic event following the Triassic collision between the North and South China blocks in China. Therefore, the Triassic plutons in the Hongseong area offer an important insight into the Triassic geodynamic history of the NE Asian region.
