Purpose: To evaluate the clinical results of anteroinferior tibiofibular ligament avulsion fracture accompanied ankle fractures treated with anatomical reduction and internal fixation. Materials and Methods: From January 2007 to April 2010, 30 cases with anteroinferior tibiofibular ligament avulsion fracture that treated with anatomical reduction and internal fixation were analyzed. The average follow-up period was 26 months (minimum 6 months). We have reviewed the bony union, complication and subjective satisfaction according to the fracture classification and method of internal fixation. Results: Among 30 cases, 28 cases were occurred in Lauge-Hansen classification supination-external rotation type, one case was fracture-dislocation and one case was Maisonneuve fracture. We have performed internal fixation with Mini screw in 11 cases, K-wire in 10 cases, repair in six cases and Mini screw & K-wire in three cases. In all cases bony union was completed. two cases in Mini screw, one case in K-wire, two cases in repair and one case in Mini screw & K-wire revealed LOM of ankle joint. Skin irritation and superficial peroneal nerve irritation happened in one case each. Other cases show good subjective satisfaction. Conclusion: Anteroinferior tibiofibular ligament avulsion fracture accompanied with ankle fracture is a good clinical outcome with internal fixation. So we should not miss out the anteroinferior tibiofibular ligament avulsion fracture in radiologic evaluation or operation room.

Background For patients with neuropathy, vasculopathy, and impairment of wound healing, treatment of a diabetic foot ulcer poses many challenges. A large number of dermal analogues have been invented in an effort to overcome these challenges. Matriderm, a dermal analogue, is made from bovine collagen and elastin. This study was conducted in order to evaluate the effectiveness of Matriderm for treatment of diabetic foot ulcers, in comparison with skin grafting. Methods Sixty patients with diabetic foot ulcer were included in this prospective study. The average age of the patients, who had type II diabetes mellitus, was 58 years old. The patients were allocated to an experimental or control group with their consents. The patients were selected with their consent for inclusion in an experimental group and a control group. Patients in the experimental group received a Matriderm appliance and a split-thickness skin graft, while those in the control group received only a split-thickness skin graft. Results A shorter hospitalization period (7.52 weeks) was observed in the experimental group than in the control group (9.22 weeks), and a shorter period of time (8.61 weeks) was required for complete healing, compared with the control group (12.94 weeks), with statistical significance (P<0.05). A higher elasticity ratio of the affected side to the non-affected side was observed in the experimental group, compared with the control group (P<0.01). Conclusions Matriderm enables effective healing and improves elasticity in treatment of patients with diabetic foot ulcer.

Purpose: This research investigated falls due to obstacles that occur among elderly people by assessing changes in the values of plantar foot force, peak force, and plantar foot pressure in elderly subjects while they were stepping over obstacles of different heights. Methods: The subjects were 20 elderly people aged 70-80 years; Pressure was measured on flat ground(0 cm), and after installing obstacles of 8 cm and 12 cm using the F-scan system, which is a resistance-type pressure sensor. A one-way analysis of variance was performed to compare pressure on each part of the foot according to various heights after collecting data using the Tekscan program. The least significant difference test was used for the post-hoc analysis, A p-value <0.05 was considered significant. Results: The force value for the toe area (parts 1, and 2) and contact pressure increased significantly with the 12 cm obstacle (p<0.05). The peak force value and the peak contact pressure for part 1 increased significantly with the 12 cm obstacle (p<0.05). Conclusion: Larger changes appeared in the functions and structure of the foot while subjects walked over obstacles of different heights compared to flatland walking. This result suggests that people have safety strategies to prevent falls, and that there is a need for a more realistic approach through practice to overcome obstacles of various heights to prevent falls.

In this study, repression of the body is defined as a restriction on natural developments or movements and a modification either temporarily or permanently of the human body in shape, color, texture and odor. In addition, it involves physical and (or) mental pain. Chinese foot-binding and the Western corset are extreme examples of female body's being repressed in the history of fashion. The analysis of this type of repression will be based on historical research and theoretical concepts such as Darwin's (1809-1882) survival condition, Freud's (1856-1939) renunciation of desire, Weil's (1909-1943) privilege, and Foucault's (1926-1984) L'Usage des Plaisirs(the use of pleasure). Chinese foot-binding symbolically represents ideal beauty, the distinction of an ethnic group, and a desire for improved social status in the struggle for political power. It also represents psychology and a esthetics of eroticism and fetishism that originate from a man's desire and his individual taste. Symbolically, the Western corset represents abundance and fecundity, obedience and devotion to religion, the sanctity of God and ideal beauty as defined by political power. It also represents psychology and aesthetics of eroticism and fetishism as man's desire and a fashion icon. In conclusion, Chinese foot-binding was pursuit of power in male ideology but Western corset was a power struggle between God and mankind.

Factor analysis was applied as a multivariate statistical technique to official genetic evaluations of type classification traits for 1,265,785 Holstein cows and 10,321 sires computed from data collected between August 1982 and June 1994 in Canada. Type traits included eighteen linear descriptive traits and eight major score card traits. Principal components of the factor analysis showed that only five factors explain the information of the genetic value of linear descriptive traits for both cows and sires. Factor 1 included traits related to mammary system, like texture, median suspensory, fore attachment, fore teat placement and rear attachment height and width. Factor 2 described stature, size, chest width and pin width. These two factors had a similar pattern for both cows and sires. In constrast, Factor 3 for cows involved only bone-quality, while in addition for sires, Factor 3 included foot angle, rear legs desirability and legs set. Factor 4 for cows related to foot angle, set of rear leg and leg desirability, while Factor 4 related to loin strenth and pin setting for sires. Finally, Factor 5 included loin strength and pin setting for cows and described only pin setting for sires. Two factors only were required to describe score card traits of cows and sires. Factor 1 related to final score, feet and legs, udder traits, mammary system and dairy character, while frame/capacity and rump were described by Factor 2. Communality estimates which determine the proportion of variance of a type trait that is shared with other type traits via the common factor variant were high, the highest ${\geq}$ 80% for final score, stature, size and chest width. Pin width and pin desirability had the lowest communality, 56% and 37%. Results indicated shifts in emphasis over the twelve-year period away from udder traits and dairy character, and towards size, scale and width traits. A new system that computes fmal score from type components has been initiated.

Purpose: The purpose of this study fracture. Materials and Methods: The clinical and radiological analysis were performed on 19 cases of the talus neck fractures who had been treated with conservative treatment or variable methods of operative treatment. Each cases followed up more than 1 year and 6 months from May 1989 to June 2001. The clinical results were analyzed according to the age, cause of injury, fracture type of Hawkins classification, associated soft tissue injury, method of treatments, complications, and Hawkins scoring system. Results: According to Hawkins classification, type I was 6 cases(32%), type II was 5 cases(26%), typeIII was 7 cases(37%), and typeIV was 1 case(5%). In all cases, complete bony union was obtained. According to the Hawkins scoring system, 8 cases(42%) were excellent and good. Avascular necrosis was 4 cases(25%). Traumatic arthritis was 10 cases which were occurred in type II, III and IV. An ankle fusion was 1 case. Conclusion: In talar neck fractures, non-displaced fracture treated by the cast immobilization and displaced fracture treated by early open reduction and internal fixation were expected good results. The complications were 77% of traumatic arthritis and 31% of avascular necrosis in type II, III and IV. We should preoperatively explain to the patient for high complication rates of traumatic osteoarthritis and avascular necrosis in the talus neck fractures.

The purpose of this study is to evalute the efficacy af the Ilizarov external fixation for the surgical treatment. of the tibial plafond fractures. We reviewed retrospectively fourteen cases of tibial plafond fractures with moderate to severe soft. tissue damage, which were fixed with Ilizarov external fixator. Using the AO Muler classification, there were four Type C1 fractures, six Type C2 and four Type C3. In most, of the cases, the ankles were operated on with other associated fractures within a few days after injury. We reduced the fracture indirectly by soft issue taxis and fixed externally across the ankle joint. using the circular external fixator with tensioned wires and ankle hinge. In cases of inadequate closed reduction, we applied limited open reduction and internal fixation. Range of motion exercise began immediately. Postoperative follow-up averaged fourteen months (ranges, 8-30 months). Overall clinical results rated good or excellent in 7 cases, fair in 4 and poor in 3. There were three cases of pin tract infection which were resolved with short-term antibiotics and local care; one delayed wound closure in a patient. whose fracture was associated with Type III open wound; one wound slough in a patient associated with Type II open wound, which was closed later by skin graft; and one osteoarthritis. From this review, we concluded that cross-ankle circular external fixation with tensioned wires with or without. limited open reduction is a reasonable alternative for the treatment of the tibial plafond fractures with severe soft tissue damage.

Purpose: To evaluate the clinical efficacy of the limited posterior approach for the surgical treatment of intraarticular fracture of calcaneus. Materials and Methods: From March 2000 to February 2006, we studied retrospectively 186 patients, 203 cases who were treated with open reduction and internal fixation through limited posterior approach and were followed up for more than 1 year. The clinical results were evaluated with Creighton-Nebraska score and circle draw test after 1 year. We checked simple AP, lateral, axial and Broden's view preoperatively and 1 year after surgery, and compared $B{\ddot{o}}hler$ angle and Gissane angle. Results: By Creighton-Nebraska score, Sanders type 2 was 86.4, type 3 was 74.3, type 4 was 62.4. And by circle draw test, type 2 was 8.9 cm, type 3 was 7.2 cm, type 4 was 5.9 cm. $B{\ddot{o}}hler$ angle and Gissane angle were $7.6^{\circ}$, $102.4^{\circ}$, and it increased to $23.5^{\circ}$, $128.6^{\circ}$ after postoperative 1 year. Conclusion: Limited posterior approach for the surgical treatment of intraarticular fracture of calcaneus was considered to an effective treatment modality.

반도체 공정시스템의 레이아웃은 대규모 자본 투자의 필요성과 제조 공정의 복잡성의 증가와 함께 그 중요성이 점점 증가하고 있다. 오늘날 대부분의 반도체 공정시스템은 같은 유형의 장비가 동일한 bay에 배치되는 bay 타입의 레이아웃 형태를 취하고 있다. Bay 타입 레이아웃은 유연성의 장점을 가지고 있지만 물류 흐름의 제어 측면에서는 많은 단점을 가지고 있다. 본 논문에서는 이러한 bay 타입 레이아웃의 단점을 보완하고자 bay 타입의 유연성은 유지하되 conter spine이 없고 bay를 통합한 형태의 새로운 반도체 레이아웃 개념인 room 타입에 대해서 비교, 연구한다. 이를 위하여 본 논문에서는 새로운 room 타입 레이아웃의 형태를 제시하고 이를 기존의 레이아웃과 반송필요 횟수와 시간, foot-print, 경유 stocker, 그리고 물류흐름 시간 등의 성과척도를 비교하여 room 타입 레이아웃의 우수성을 보인다.

Purpose: Pilon fracture is caused by high energy and axial compression forces, and it is often associated with severe comminution and soft tissue injury. Recently, limited internal fixation of this fracture may avoid the soft tissue complications associated with formal open reduction and internal fixation and avoid incongruity of joint margin associated with conservative treatment. We have treated Ovadia and Beals type II or III pilon fracture with limited internal fixation and the results were satisfactory. Materials and Methods: We analyzed 15 cases of Ovadia and Beals type II or III fractures who were treated by limited internal fixation(K-wire or screw fixation) from January 1995 to December 2000. The average follow up period was 20 months(range, 12 to 38 months). According to the Ovadia and Beals classification, seven cases were type II, and eight cases were type III. Radiographic results were assessed by Ovadia and Beals criteria. We also assessed the functional results by Mast and Teipner criteria. Results: Radiographic results showed good in 67% and fair in 33% of cases. Clinical results showed good in 73% and fair in 27% of cases. There were no complications such as wound infection and skin necrosis, but traumatic arthritis were 2 cases. Conclusion: Pilon fractures are high energy injuries with significantly associated soft tissue damage and traumatic arthritis. Limited internal fixation offers good solution to Ovadia and Beals type II or III fracture.
