  • Study Design: Retrospective review. Purpose: To detect the effect of cannulated (poly-axial head) and solid (mono-axial head) screws on the local kyphotic angle, vertebral body height, and superior and inferior angles between the screw and the rod in the surgical management of thoracolumbar fractures. Overview of Literature: Biomechanics studies showed that the ultimate load, yield strength, and cycles to failure were significantly lower with cannulated (poly-axial head) pedicle comparing to solid core (mono-axial head). Methods: The medical charts of patients with thoracolumbar fractures who underwent pedicle screw fixation with cannulated or solid pedicle screws were retrospectively reviewed; the subjects were followed up from January 2011 to December 2015. Results: Total 178 patients (average age, $36.1{\pm}12.4years$; men, 142 [84.3%]; women, 28 [15.7%]) with thoracolumbar fractures who underwent surgery and were followed up at Hamad Medical Corporation were classified, based on the screw type as those with cannulated screws and those with solid screws. The most commonly affected level was L1, followed by L2 and D12. Surgical correction of the local kyphotic angle was significantly different in the groups; however, there was no significant difference in the loss of correction of the local kyphotic angle of the groups. Surgical correction of the reduction in the vertebral body height showed statistical significance, while the average loss of correction in the reduction of the vertebral body height was not significantly different. The measurement of the angles made by the screws on the rods was not significantly different between the cannulated (poly-axial head) and solid (mono-axial head) screw groups. Conclusions: Solid screws were superior in terms of providing increased correction of the kyphotic angle and height of the fractured vertebra than the cannulated screws; however, no difference was noted between the screws in the maintenance of the superior and inferior angles of the screw with the rod.

  • The research analyzs characteristics of body types for the Chineses women based on the different life style and to compare the differences of body type with Korean women. The measurement had took in Beijing and Seoul in 1999. As a result of comparing Chinese and Korean women'body measurements, it was found that Chinese women are shorter and obser than Korean women. Besides, chinese arms and upper body are shorter, and their body is thicker compared with their relatively flat chest. After all, Cheinese women'chests are more voluminous, while their shoulders are drooped more, although their shoulder size is almost as same as Korean women'. By used factor analysis, 8 factors were extracted from body measurements : body obesity, vertical body size, ankle and knee sizes, head size, front upper body length, shoulder size, form and size of neck and upper chest, drooping of shoulders, and size of hip. It was found that Chinese college women are obser with larger vertical body length and front upper body length. And their shoulders are more drooped with larger hip. But two nations'female students did not show any differences in the sizes of ankles, knees, head and shoulders.

  • Paraganglioma is a relatively rare, generally benign and slow growing tumor arising from widely distributed paraganglionic tissue thought to originate from the neural crest. In the head and neck region, paraganglionic tissue is distributed in the superior and inferior paraganglia such as the carotid body, the vagal body, and the jugulotympanic region. Approximately 10% of patients with paraganglioma have a family history of such tumors. Multiple lesions can be found in 26% of patients with family history. It is important to distinguish between paraganglioma and atypical carcinoid tumor and medullary thyroid cancer. This can be done with histopathologic evaluation and immunohistochemical markers. Complete excision is recommended for the treatment of this tumor. Paraganglioma is particularly aggressive and rapid recurrence of paraganglioma is common after local resection. We present a case of malignant paraganglioma in the neck which recurred 2 months after local resection. We suppose that radiation therpay could be the last option for the treatment in this clinical setting.

  • The head and face are the most complicated structures of the human body. However, unlike apparel products, many of the head and face related products are produced in unisex or one-size-fits-all. Therefore, it is necessary to provide a practical analysis that reflects these size structures. This study analyzed head and face measurements of men, women, and both men and women; its purpose lying in clarifying the differences and commonalities between the measurements of men and women and discovering the possibility of integrating analysis on measurements of men and women. 3D face and head measurement data of men and women from 20 to 29 years-old from Size Korea's 6th human body size data were analyzed for this study. The mutual 9 factors were extracted as the results of the three factor analyses (both men and women) separately and men and women integrated. However in the cluster analysis based on the 9 factors, men and women showed mutual characteristics and different landscape in group types and distribution. The commonalities and differences between men and women observed in this study should be applied to the sizes of head and face products.

  • This study examined the Yemou(a hat for a dead woman) from the ladies' clothes excavated from the Lady Lee's tomb in order to trace the significance of the clothing composition and its social origin in the Chosun dynasty. The compositional characteristic of Yemou covers the body of the hat which is not connected with the cover, Wonsal which has a round shape that covers the face of the dead body, and two Gae(a ribbon on the backside of a hat). Seongho Lee-ik(one of representative Confucian scholars in the Chosun dynasty) stated in his book entitled "Seongho Notes", that the structural elements of Yemou originated in Yum(wrapping cloth for the head of a dead body). According to Seongho, Yemou's body part came from the scarf used to cover the head. Wonsal(the cloth of round shape for covering the face) and Gae were derived from Yum made of two ends of long cloth for covering and binding the head of a dead body. Yongjae Kim-kunhang(one of Confucian scholars in the late-Chosun dynasty) demonstrated in his "Yongjae Collection" the social background of the emergence of Yemou. Yemou was the hat produced from the process of nationalizing the Chinese courtesy of clothing. In other words, Bokgun(a man's hat) in the Chosun dynasty replaced the Chinese Yum. Unlike the Chinese custom, man and woman in the Chosun dynasty wore different clothes respectively. According to the clothing custom of the Chosun dynasty a woman wore a female hat, Yemou instead of men's Bokgun.

  • Purpose : The purpose of the research was to analyze foot pressure, foot temperature, and correlation between foot pressure and foot temperature to grasp impact on foot pressure and body temperature distribution chart depending on functional difference of leg length. Method : After measuring leg length, put 15 students whose functional difference of leg length was over 10mm to difference group and 15 students whose functional difference of leg length was under 5mm to normal group and categorize soles of foot into 6 sections of hallux head, 1st metatarsal head, 2-4 metatarsal head, 5 metatarsal head, lateral heel, and then measure by foot pressure analyzer to analyze characteristic of pressure distribution and classify into front of the lower leg, back of the lower leg, soles of foot and measure by body temperature analyzer to analyze by checking body temperature. Result : Weight difference depending on foot pressure and body temperature was bigger when functional difference of leg length was bigger, and it could be confirmed that foot pressure and body temperature of short leg side were higher than those of short leg side. Thus, if difference exists in leg length, weight load on short leg side increases which results in higher foot pressure and body temperature, therefore enabling an assumption that mechanical problem will occur in short leg. Conclusion : When functional leg length inequality, weight bearing and pressure was getting high as a result, temperature was getting high in short leg.

  • The larvae and juveniles of Porocottus leptosomus belonging to the family Cottidae were collected (n = 95, 3.9-16.5 mm in body length, BL) from Busan, Korea, in March 2015. The larvae and juvenile were identified using DNA barcoding as P. leptosomus, and their morphological description was presented in detail. The yolk-sac larvae (3.9-5.6 mm BL) body was slightly compressed, the head was large, the eye was round and large, and the anus was before the middle of the body. The preflexion larvae (5.2-10.0 mm BL) body length drastically increased; caudal fin rays began to occur. The flexion larvae (9.4-11.8 mm BL) notochord flexion started; dorsal, pectoral, and anal fin rays began to occur; pelvic fin buds are seen; they possessed a pair of parietal spine; and a pair of supraocular cirri was first to develop. At 12 mm BL, the notochord was completely flexed. The larva stage (3.9-12.6 mm SL) had the stellate melanophores in the head, isthmus, gut, and tail (along to the ventral midline). During the juvenile stage (11.4-16.5 mm BL), melanophores covered the head and began to form five black bands on the side of the body. The larvae of P. leptosomus spent pelagic life, but moved to the bottom during the juvenile stage. The larvae and juveniles of P. leptosomus differ from other cottid larval fishes by body shape, melanophore head pattern, and spine development. P. leptosomus can be distinguished from Porocottus allisi by morphological development and the occurrence of larval fish: preopercular spine development, melanophore pattern, and caudal fin development.

  • Purpose: This study investigated the coordination and contribution of body segments during functioning. Methods: The relevant literature related to body segments and function were reviewed. Results: Efficient control of function is considered with regard to a participant's ability to perform a sequence of movements in body segments, which progresses from the head to the arm, trunk, pelvis, and leg segments. Each segment performs a specific role, which environment explorer using visual information for the head, reaching and grasping for the arms, a stabilizer for the trunk, and the distribution of COM in the pelvis and leg. Conclusion: During any of the movements, the momentum generated by the proximal segments is transferred to the adjacent distal segments in an appropriate sequence. In assessing function for clinical intervention strategies, the segment coordination, segment sequence, transfer of the center of body mass, asymmetrical ratio, muscle activity, and compensatory strategies should be considered.
