For a complex scheduling system like time table construction, its optimal solution, if exists, is hard to obtain. In this paper, the scheduling environment is reasonably confined as where objects have their own events competing for better slots on boards, and objects have their own board slot preferences and belong to one or more classes of the society which globally constrains them. Here, two phase method is suggested, where the first phase is human-like preference driven and the second phase is for fine tuning by considering all the factors given. Designed and implemented in our system HI-SCHED are dynamic object switching, temporal-constraint-driven intelligent backtracking, case-based revisions, object-based approach, and so on. Some satisfaction degrees are also defined to measure the usefulness of our method. In addition, look-ahead dynamic object switching is considered, and additional global constraints are introduced and processed. A simple scheme is also used to verify the usefulness of the post processing scheme.

Purpose: We try to evaluate the clinical results of the acute Achilles tendon rupture treated with Krackow suture technique. Materials and Methods: We reviewed 27 patients with acute Achilles tendon rupture treated between October 2005 and September 2007. There were 26 complete ruptures and 1 incomplete rupture. All were ruptured at tendinous area. There were 21 men and 6 women, and mean age was 38 years. We repaired ruptured Achilles tendon with Krackow suture technique. The results were evaluated with Arner-Lindholm scale for patients' satisfaction, strength of calf muscle power, calf circumference, and ankle motion. The average follow-up was 29 months. Results: The patients' subjective clinical results was excellent in 25 cases and good in 2 cases. There were 15 cases of less than 1 cm, 6 cases of 1${\sim}$3 cm, and 1 case of more than 3 cm in the calf circumference difference between the normal and affected leg. There were 20 cases of less than 5 degrees, and 2 cases of more 5 degrees in the difference of range of motion between the normal and affected ankle. We had an experience of postoperative deep infection in one diabetic patient. Conclusion: We had a good clinical result for acute Achilles tendon rupture treated with Krackow suture method. So we recommand Krackow suture technique for acute Achilles tendon rupture.

Purpose: The purpose of this study was to evaluate the clinical results of the old Achilles tendon rupture treated with modified flexor hallucis longus (FHL) tendon transfer. Materials and Methods: Seventeen patients with old Achilles tendon rupture treated with modified FHL tendon transfer between March 2004 and February 2008 were enrolled in this study. Technically FHL was pass through the distal portion of the ruptured tendon instead of the drilled hole made on the calcaneus. The mean age of the patients was 37 years (range, 22~67 years), mean follow-up period was 28 months (range, 12~30 months). Patients' subjective satisfaction, calf circumferential diameter, range of motion of ankle and AOFAS ankle-hind foot score and Arner-Lidholm score was evaluated. Results: The average gap between the ruptured tendon was 52 mm (range, 47~56 mm). The AOFAS score improved from 47 pre-operatively to 91 points at the last follow-up. Sixteen patients were satisfied with the result free from discomfort, a patient had mild discomfort who had DM. fourteen patients had decreased range of motion less than 5 degrees while 2 patients had more than 7 degrees decrease compared to the intact side but had no discomfort in daily activities. Nine patients had less than 1 cm calf circumferential diameter difference and 7 patients had 1 to 3 cm diameter difference compared to the intact side. One who had more than 3 cm diameter difference had deteriorated muscle strength. Conclusion: Modified FHL tendon transfer can be a useful technique for the treatment of old Achilles tendon rupture when the gap is with large gap placed too proximal.

Purpose: To evaluate the short-term clinical outcomes of total ankle arthroplasty for the post-traumatic osteoarthritis. Materials and Methods: Fourteen patients who had undergone total ankle arthroplasty from February 2005 to June 2006 were reviewed. Eleven patients were male and three patients were female. The mean age was 52.8 years (range, 33 to 69 years). The mean follow-up duration was 15.9 months (range, 12 to 24 months). Primary injuries were pilon fractures in eight cases, malleolar fractures in three, ankle syndesmotic injury in one, talus fracture and dislocation in one, and distal tibial physeal injury in one. Visual analogue scale (VAS), Range of motion (ROM), American Orthopaedic Foot and Ankle Society (AOFAS) score and complications were evaluated. Results: The mean VAS improved from 8.6 preoperatively to 2.6 at last follow-up. The mean ROM improved from 24.6 degrees preoperatively to 33.1 degrees postoperatively. The mean AOFAS score improved from 44.5 points preoperatively to 75.1 points postoperatively. Radiographically, all components were stable, but there were component malpositions in two cases, including one varus malposition of tibial component and one increased anterior translation of talar component. Complications were deep infection in one case, intraoperative malleolar fracture in three, marginal wound necrosis in two, and heterotopic ossification in one. One prosthesis was revised because of deep infection. Conclusion: Total ankle arthroplasty for the post-traumatic osteoarthritis is believed to be an useful method for preservation of the motion, relief of the pain and high satisfaction of patients in short-term results.

This study was conducted to use the feedback of health personnel to improve the Visiting Health Service. The data was collected from 471 Home Health Workers serving 24 local health organizations in the Kyung-Pook province. 62.5% of the respondents were men under thirty-nine years of age. 92.8% of the respondents are married. 47.1% had degrees from junior colleges. It was ascertained 52.7% of the workers visited their patients six to twelve times within a six month period. And one to three patients were visited per day by one worker. Workers of older age, higher job position, and more experience were more positive in their feedback about the program. In addition, local health center employees, including nurses, were more positive about the program. Younger workers with a higher level of education, less experience, and lower job position had more insight into the problems of the program. Deeper insight into these problems led to a more negative conception of the program. Older workers with higher ranking jobs were found to be most competent. in their jobs. Workers at the main health center were assessed higher than the workers at the health sub-center or the primary health post. In addison nurses at all centers were found to be slightly more competent than the nurses' aide. The primary health post established the highest degree of patient satisfaction. It was discovered that the more positive the workers felt about the program, the higher their patient satisfaction feedback. There was a positive correlation between management assessment and patient satisfaction. This means that better program management was found to produce higher patient satisfaction. Workers feel being more educated about patient management would lead to better service. However, they take no action to produce these results. Where the problems of the system are most commented upon, the need for further education is greatest. Through multiple regression analyses it is apparent that the assessment of patient management is the greatest variable affecting patient satisfaction of patients is dependent on the management by the visiting health worker. Therefore, the development of the visiting health program is highly dependant on the feedback of those workers with a negative conception of the program. So the development of programs, motivation, education and training must be established. These works would lead to active participation by visiting health workers in the improvement of the Visiting health program.

Purpose: Pilon fracture has several serious complications such as joint stiffness, arthrosis and delayed angular deformity. We report short-term results of new treatment modality using distracted dynamic external fixators and early controlled ankle motion. Materials and Methods: Eight cases of severe pilon fractures for which we tried small plate fixation and additional distracted dynamic external fixators from July 2007 to June 2009 were included. Half passive continuous ankle joint motion was allowed under free hinged ring fixators after the operation. The external fixators were removed after two or three months from the surgery. We investigated joint space by radiograph, joint pain, range of motion, patient's satisfaction of treatment protocol. Results: Joints were distracted when external fixators were applied and mean 28% of space loss developed after removal of external fixators. In most of cases, satisfactory alignments were maintained. Regarding range of joint motion, mean dorsiflexion angle was 15 degrees and mean plantarflexion angle was 32 degree in the condition of wearing external fixators. There was mean 8% reduction of range of motion but no further progression of ankle stiffness after removal of external fixators. Dorsiflexion was not improved after that, but plantarflexion angle was improved 10% even after removal of external fixators. Patients were generally in compliance with the treatment protocols with high level of satisfaction. Conclusion: We got good results with distracted dynamic external fixators and early continuous half-passive joint motion for pilon fractures in terms of joint pain and range of motion. Therefore we suggest this new protocol as an alternative modality for severe pilon fractures.
