The general n/m job-shop problem is easy to state what is required, but it is extremely difficult to make any progress whatever toward a solution. This paper was first to examine a heuristic procedure of general n/m scheduling generation focused on the procedure of MWRK (Most Work Remaining) presented by Giffler and Thompson (1960) among others. Then modified procedure was proposed to obtain better solution in light of the key measure of performance compared with that of the literature presented by Baker (1974). The modified procedure then has been extended to other example problem to test the better results and to assure the properness of application.

Background: Painful experiences during procedures such as prolotherapy and intramuscular stimulation are stressful to patients and can affect the treatment outcome. We present a method for relieving pain and increasing the level of patient comfort during the procedure. Methods: Twenty six patients who requested sedation anesthesia during the procedure were examined. All patients were injected with 500 ml of 0.9% normal saline and were monitored by electrocardiography, blood pressure and pulse oximetry. The patients were supplied with oxygen (3 L/min) through a nasal cannula. Midazolam (0.02 mg/kg) and alfentanil ($8{\mu}g/kg$) was injected before the procedure and a bolus injection was administered during the procedure if patients felt any pain. The duration of the procedure, the total amount of drugs, the changes in the systolic blood pressure, heart rate, pulse oxygen saturation, sedation and pain level during procedure, satisfaction scale after the procedure, complications and the incidence of amnesia were evaluated. Results: Twenty one patients had a moderate level of sedation, 15 patients did not feel any pain during the procedure, 17 patients had high level of satisfaction (8-10). No patient experienced complications after the procedure, or unstable vital signs, and 6 patients could not remember the procedure. Conclusions: Sedation anesthesia is a safe method for relieving pain during the procedure, and most patients had a high level of satisfaction.

General purpose computing applications have not yet been thoroughly explored in procedure level speculation, especially in the light-weighted profiling way. This paper proposes a light-weighted profiling mechanism to analyze speculative parallelism characterization in several classic general purpose computing applications from SPEC CPU2000 benchmark. By comparing the key performance factors in loop and procedure-level speculation, it includes new findings on the behaviors of loop and procedure-level parallelism under these applications. The experimental results are as follows. The best gzip application can only achieve a 2.4X speedup in loop level speculation, while the best mcf application can achieve almost 3.5X speedup in procedure level. It proves that our light-weighted profiling method is also effective. It is found that between the loop-level and procedure-level TLS, the latter is better on several cases, which is against the conventional perception. It is especially shown in the applications where their 'hot' procedure body is concluded as 'hot' loops.

Purpose: The Inaba's procedure, the treatment of osmidrosis axillae, has the advantages of low recurrent rate and easy to learn, yet it produces early postoperative discomfort and scar formation by tie - over dressing. The authors modified the Inaba's procedure by using delayed suture of the incision wound and omitting tie - over dressing. The comparative study of Inaba's procedure and its modification was performed to confirm the advantages of modified procedure. Methods: The study contains the retrospective analysis of the medical records of 296 patients with osmidrosis who were treated using the Inaba's procedure from December, 1996 to February, 2007. The study also contains the prospective analysis of 20 patients, from March, 2007 to July, 2008, who were treated by the modified Inaba's procedure with delayed suture of the incision wound and gentle pressure dressing instead of tie - over dressing. The operative results of two groups were compared and verified by Mann - Whitney U test(SPSS 12.0). Results: The incidence of complications was 14.5% in the Inaba's procedure, whereas 6.2% in the modified Inaba's procedure. Both procedures have the same basic surgical procedure in terms of the location of incision site and subdermal shaving of the sweat glands, and therefore similar good results were obtained in the aspect of postoperative axillary odor, recurrent rate and postoperative condition of axillary hair. Certainly, the modified Inaba's procedure had better outcome in each element of PSS(Patient Scar Self-Rating Scale), compared to the Inaba's procedure. In addition, the modified Inaba's procedure showed a statistical significance in dressing - related pain reduction and overall satisfaction. Conclusion: The modified Inaba's procedure had advantages of decreased early postoperative complications such as hematoma, discomfort and pain caused by tie - over dressing, and decreased scar formation. However, the drawback was delayed suture of the incision wound after 48 hours.

We consider the question of efficiency of the Bayes sequential procedure with respect to the optimal fixed sample size Bayes procedure in a simple vs. simple testing problem for data coming from a general nonregular density b(.theta.)h(x)l(x < .theta.). Efficiency is defined in two different ways in these caiculations. Also, the minimax sequential risk (and minimax sequential stratage) is studied as a function of the cost of sampling.

Recto-vaginal fistulas are difficult to treat due to their high recurrence rate. Currently, no single surgical intervention is universally regarded as the best treatment option for recto-vaginal fistulas. We present a case of recurrent recto-vaginal fistula surgically treated with a gracilis pull-through flap. The surgical goals in this patient were complete excision of the recto-vaginal fistula and introduction of fresh, vascularized muscle to seal the fistula. A defunctioning colostomy was performed 1 month prior to the present procedure. The gracilis muscle and tendon were mobilized, pulled through the freshened recto-vaginal fistula, passed through the anus, and anchored externally. Excess muscle and tendon were trimmed 1 week after the procedure. Follow-up at 4 weeks demonstrated complete mucosal coverage over an intact gracilis muscle, and no leakage. At 8 weeks post-procedure, the patient resumed sexual intercourse with no dyspareunia. At 6 months post-procedure, her stoma was closed. The patient reported transient fecal staining of her vagina after stoma reversal, which resolved with conservative treatment. The fistula had not recurred at 20 months post-procedure. The gracilis pull-through flap is a reliable technique for a scarred vagina with an attenuated recto-vaginal septum. It can function as a well-vascularized tissue plug to promote healing.

Purpose: This study was performed to evaluate clinical and radiographical results of treatment of chronic lateral ankle instability with modified Brostrom procedure. Materials and Methods: This is a retrospective study of 22 cases in 22 patients treated with modified $Brostr{\ddot{o}}m$ procedure under the diagnosis of chronic lateral ankle instability from May 2000 to August 2004. Average age was 32.3 years. Average follow-up period was 23 months. Preoperative and postoperative radiographs of ankle anteroposterior view, lateral view and varus stress view were analyzed. The clinical evaluation was performed according to the Americal Orthopaedic Foot and Ankle Society scales. Results: After the modified $Brostr{\ddot{o}}m$ procedure, Americal Orthopaedic Foot and Ankle Society scales score was improved by average 28 points. Among the 22 cases, 13 cases were excellent, 3 cases good, 4 cases fair, and 2 cases poor with satisfaction of 73%. Five cases had intermittent ankle pain of whom 3 cases had difficulty during competitive sports activity. Lateral tilting of talus improved by average 5.4 degrees on varus stress view. Conclusions: The modified $Brostr{\ddot{o}}m$ procedure is one of the most effective methods for treating of chronic lateral ankle instability.

In this paper we develop an exponentialization procedure for the modelling of open FMS networks with general processing time at each station and limited buffer size. By imposing a reasonable assumption on the solution set, the nonlinear equation system for the exponentialization procedure is formulated as a variational inequality problem and the solution existence is examined. The efficient algorithm for the nonlinear equation system is developed using linearized Jacobi approximation method.

Percutaneous first annular pulley (A1 pulley) release, which has been increasingly used to treat trigger fingers, has been widely established as a safe and simple procedure. Multiple studies have reported positive results of percutaneous A1 pulley release. In this study, however, we report cases of patients who developed complications after undergoing percutaneous A1 pulley release at local clinics. A total of six patients visited our hospital for infectious complications after percutaneous A1 pulley release. Various sequelae such as damage to normal structures, insufficient procedure, and tissue necrosis were observed during the exploration. A retrospective study was conducted to identify the cause and trend of the observed complications by instruments (HAKI knife or needle). In the HAKI knife group, there was a tendency for damage to normal structures, while in the needle group, an insufficient release or serious soft tissue necrosis was observed. Based on these cases, our findings confirm the existence and characteristics of infectious complications following the percutaneous A1 pulley release. We further identify that the type of instrument used predicts the nature of complications. Thus, reliable and skilled performance of the procedure by experts is essential for safe treatment.
