  • We particularly emphasized how to determine the number of replications with sequential and multistage procedures. So, the t-test is used to achieve some predetermined level of accuracy efficiently with loss function in the case of normal, chi-squared, an exponential distributions. We provided that the relevance of procedures are sequential procedure, two-stage procedure, modified two-stage procedure, three-stage procedure and accelerated sequential procedure. Monte Carlo simulation is carried out to obtain the stopping sample size that minimizes the risk.

  • 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.

  • This study was aimed at analyzing the three-step seismic performance evaluation procedure of Korea Infrastructure Safety Cooperation and proposing a new procedure suitable for unreinforced masonry buildings in Korea. For the study, it was investigated the performance evaluation results of five example URM buildings. First of all, it was found that the performance evaluation procedure for the URM buildings should be different from that for the other structural systems. As a result, a simple procedure of seismic performance evaluation was proposed, which includes elimination of elastic and inelastic push-over analysis and reduction of performance levels and evaluation steps. With the simple procedure, the URM buildings could be evaluated more easily than the other structures. It would be expected that the procedure can provide structural engineers with a simple and easy way to evaluate the seismic performance of the Korean URM buildings. Nevertheless, the procedure must be revised continuously by reflecting new research products for the URM buildings in Korea.

  • 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.

  • The Computerized Procedure System (CPS) is one of the primary operating support systems in the digital Main Control Room. The CPS displays procedure on the computer screen in the form of a flow chart, and displays plant operating information along with procedure instructions. It also supports operator decision making by providing a system decision. A procedure flow should be correct and reliable, as an error would lead to operator misjudgment and inadequate control. In this paper we present a modeling for the CPS that enables formal verification based on Petri nets. The proposed State Token Petri Nets (STPN) also support modeling of a procedure flow that has various interruptions by the operator, according to the plant condition. STPN modeling is compared with Coloured Petri net when they are applied to Emergency Operating Computerized Procedure. A converting program for Computerized Procedure (CP) to STPN has been also developed. The formal verification and validation methods of CP with STPN increase the safety of a nuclear power plant and provide digital quality assurance means that are needed when the role and function of the CPS is increasing.

  • Gastrointestinal and colonic endoscopic examinations have been performed in pediatric patients in Korea for 3 decades. Endoscopic procedures are complex and may be unsafe if special concerns are not considered. Many things have to be kept in mind before, during, and after the procedure. Gastrointestinal endoscopy is one of the most frequently performed procedure in children nowadays, Since the dimension size of the endoscopy was modified for pediatric patients 15 years ago, endoscopic procedures are almost performed routinely in pediatric gastrointestinal patients. The smaller size of the scope let the physicians approach the diagnostic and therapeutic endoscopic procedures. But this is an invasive procedure, so the procedure itself may provoke an emergence state. The procedure-related complications can more easily occur in pediatric patients. Sedation-related or procedure-related respiratory, cardiovascular complications are mostly important and critical in the care. The endoscopists are required to consider diverse aspects of the procedure - patient preparation, indications and contraindications, infection controls, sedation methods, sedative medicines and the side effects of each medicine, monitoring during and after the procedure, and complications related with the procedure and medicines - to perform the procedure successfully and safely. This article presents some important guidelines and recommendations for gastrointestinal endoscopy through literature review.

  • The problem of selecting the gamma population with the largest mean out of k gamma populations, each of which has the same shape parameter is considered. An elimination type two-stage procedure is proposed which guarantees the same probability requirement using the indifference-zone approach as does the single-stage procedure of Gibbons, Olkin and Sobel (1977). The two-stage procedure has the highly desirable property that the expected total number of observations required by the procedure is always less than that of the corresponding single-stage procedure regardless of the configuration of the population parameters.

  • In this paper, a rescheduling procedure is developed for shipbuilding master production schedule. Shipyard initially develops backward production schedules for the entire shipbuilding process, and then refines the schedule by stage. The rescheduling procedure of this paper tries to resolve the schedule discrepancies between the outdoor backward schedule and the refined indoor schedule. Through the proposed rescheduling procedure, outdoor schedule can be successfully adjusted using buffer days and duration reduction. An Object-oriented program is also developed to automate the procedure. We can observe the improvement on productivity and quality of rescheduling works from the application of the developed procedure.

  • In this paper a heuristic procedure for a resource constrained project scheduling problem with multiple crashable modes is presented. A similar heuristic procedure by Ahn and Erengue was recently introduced, but the procedure assumes the resource capacities constant over the project life. The Procedure of this paper is able to deal with the resource capacities varying over the project life. The computational results with a set of 110 test problems demonstrate the efficacy of the heuristic procedure.
