The purpose of this investigation is to enhance the survival rate of patients by transporting them to the hospital within the golden hour through the operational improvement of emergency dispatch instruction. To this end, problems and improvements of current operating system were derived by carrying out a survey against paramedics of Incheon city in 2012 and analyzing the current emergency dispatch instruction. This study analyzed the emergency activity daily reports for one year from January 1 through December 31, 2012 and researched the consciousness of 119 emergency medical technician. According to the analysis of the survey, there were no meaningful differences in the on-site arrival times per triage. Therefore, the item of 'Emergency Classification' specified in the emergency dispatch instruction needs to be integrated in the scheme of "triage". Also, the feedbacks of the emergency action log and the emergency dispatch instruction are necessary for 'duty for operation' to review the adequacy to the severity after the end of emergency operation. Finally, the improvement of the system for the continuous communication between the paramedics and the command staff is necessary. This improvements as stated above are expected to contribute to raise survival rate of patients.

Arthroscopic anterior cruciate ligament reconstructions using bone-patella tendon-bone have been considered the best method by which others are compared. The notchyplasty is one of the important steps of this procedure and it is emphasized recently to prevent retear of the reconstructed ACL caused by impingement. However, until now, there is controversy about adequate amount of notchyplasty. Also, it is hard to examine the adequacy of notchyplasty even in the arthroscopic field, The purpose of this paper is to describe the surgical technique of notchyplasty, using the flexible reamer and preliminary result of its operation. In this study the results of ACL reconstruction with notchyplasty which is made by us were analized from January. 1994 to December, 1995. The results were as follows: 1. The notchyplasty with flexible reamer is the method that can be obtained adequate amount of removal, perfectly smooth notchyplasty. 2. The range of motion of the affected knee joint was normal ROM after post operation 6 month. 3. In the last follow up, 2 cases were positive in anterior drawer test 4 cases were positive in Lachmann's test and 1 knee was positive in Pivot shift test 4. Average Lysholm knee scoring scale was 70 points at preoperative and 92 points at the last follow up.

The necessity of urban regeneration is recently increasing because of the deterioration existing urban area and the slowdown of new development operations. The urban regeneration is differentiated from other private operations by its public characters, which is the basis of public support. This character demands verification of the adequacy for public finance support by monitoring urban regeneration planning and operation. Therefore, this study aims to show the monitoring indicators and its application in legal system for urban regeneration through the examination of foreign countries cases. London, San Francisco, and France urbanism regulation and planning system show the measure for introducing urban regeneration monitoring system into korean urbanism institution. This study is significant by suggesting the circulation structure of urban regeneration by linking planning, operations and monitoring phases. The monitoring system permits improvement of urban regeneration by clarifying objects and ameliorating efficiency by continuos observation and application of its evaluation.

This study drew performance management factors analyzed a causal link between acceptance and satisfaction of performance management to present the method for promoting acceptance on the performance management system that most of the public enterprises, government-affiliated organizations are implementing. To achieve this, qualitative analysis and quantitative analysis were conducted in parallel through in-depth case studies and surveys. The results of this study are as follows. First, the analysis of the performance management factors with preceding studies shows that performance management indicators, performance management operations and performance management communications. Second, from the causal relationship of performance management factors affecting performance management acceptance reveals that performance management operation has statistical significance. Third, the analysis of the effect of performance management factors on the management satisfaction shows that operation and indicator of the performance management have statistical significance and reflecting the performance indicators to business, adequacy of target level, training, system support and CEO's Leadership have been revealed as important variables to the management satisfaction. Fourth, the result of the analysis on casual connection between acceptance and satisfaction of the performance management shows that improving management acceptance has a direct impact on satisfaction because performance management receptiveness were deemed statistically significant. Fifth, the result of the in-depth case studies on improving performance management acceptance shows that public enterprises have been putting in an effort to design indicators and try to encourage internal member's involvement during the monitoring and evaluation. The quantitative analysis based on survey has turned out that performance management operation and performance management indicators have statistical significance. The qualitative analysis by in-depth analysis shows that public enterprises put a lot of effort to performance management indicators and communication between internal members. As a result, commitment to performance management operation is required to improve the performance management acceptance. In other words, a detailed implementation plan for training, information system support, and CEO's leadership has to be established and ought to be pushed.

This study was conducted to analyze the status radiological imaging examinations assessment in Korea medical institutions conducted in the public sector and suggest a direction for improvement. Among the assessment of medical institutions, the main assessment related to radiographic imaging examinations are the certification evaluation of medical institutions and the adequacy assessment of radiographic imaging examinations. The certification evaluation of medical institutions evaluates the image inspection operation process, provision of accurate results, and compliance with safety management procedures. In the assessment of adequacy of radiographic imaging examinations, structural indicators related to manpower and equipment, patient evaluation implementation rate, and exposure reduction programs were included. However, for safer and higher-quality radiological imaging examinations, it is necessary to increase the participation rate of medical institutions in certification evaluations. In addition, it is necessary to improve the manpower indicator, and incentive payments can be considered to induce quality improvement of medical institutions in the future. Integrated management of radiation exposure at the national level should also be carried out simultaneously.

Globally, wind power development is experiencing dramatic growth and wind power penetration levels are increasing. Wind generation is highly variable in time and space and it doesn't guarantee the system reliability and secure system operation. As wind power capacity becomes a significant portion of total generation capacity, the reliability assessment for wind power are therefore needed. At present, this operational reliability assessment is focusing on a generation adequacy perspective and does not consider transmission reliability issues. In this paper, we propose the critical transmission operating constraint prediction(CTOCP) system with high wind power penetration to enhance transmission reliability.
