Purpose: Nursing puts much weight en the organization of hospital. Therefore it is necessity to improve nursing care. One of the most important things is to secure confident nurses and to develop nurse' potentiality. It directs nurse evaluation system. The concept of "performance appraisal tools" is extremely important in evaluation system. Therefore, the purpose of this study aims to define performance appraisal process. Method: In order to do this, two main study has been observed interviewing appraisers and employees in-depth and analyzing performance appraisal tools of seven hospitals and analysed validity, reliability, acceptability and practicability. Result: The result of this study can be summarized as follows; Firstly, the result of analysis of performance appraisal tools. Regard to validity, Hospitals had a typical goal, but had not put to practice use. Regard to reliability, 1) Appraisal rule had been focused on appraiser's error, how to avoid. 2) 5 hospitals accessed nurses with relative rating and 2 hospitals with absolute rating both in practice. 3) 3 hospitals informed nurses the result of performance appraisal but 4 hospitals did not. 4) All hospitals in this study had conducted superiors rating. Regard to acceptability, 1)Rating scale method had been implemented by 6 hospitals and among those conducted beth ranking method and descriptive method. 2) Most hospitals had focused on personal traits in performance appraisal factors. Regard to practicality, The term of appraisal took $10{\sim}14$ days; performance appraisal happened 1 or 2 times per year; appraisal factors were based on 10 different items. Secondly, the result of in-depth interview with head nurses and staff nurses Regard to validity, head nurses and nurses wared that the goal of performance appraisal is to develop nurse's ability. Regard to reliability, head nurses pointed out that they were doubt of the justice of performance appraisal and they should have got training. Nurses insisted that raters should have been trained due to lack of qualification of appraiser; Head nurses and nurse proposed to convert form relative rating to absolute rating; to inform the result of appraisal; to implement peers rating. Regard to acceptability, One of the critical problems of performance appraisal tools was abstract of appraisal factors ; Lack of job analysis. Regard to practicality, Head nurses used to take overtime for appraisal. There was only a little respond despite of their efforts. Nurses questioned that appraisal tools exist for only appraisal; there was less cost-effectiveness. Conclusion: Based en these findings, it could be suggested to improve the performance appraisal tools for nurses evaluation. Firstly, it is necessary to describe goal of performance appraisal clearly set up, so that nurses could improve their positive word performance and develop their potentiality. Secondly, it is necessary to obtain various training on raters, implement absolute rating and inform the result of appraisal to nurses and use peers rating. Thirdly, it is necessary to convert from rating scale method to management by objectives or behaviorally anchored rating scale and take measurable appraisal factors based en job analysis. Finally, it is necessary to reduce the appraisal cost but increase effectiveness of performance appraisal.

The recent "Log4j Security Vulnerability Incident" has occurred, and the information system that uses the open source "Log4J" has been exposed to vulnerabilities. The incident brought great vulnerabilities in the information systems of South Korea's major government agencies or companies and global information systems, causing problems with open source vulnerabilities. Despite the advantages of many advantages, the current development paradigm, which is developed using open source, can easily spread software security vulnerabilities, ensuring open source safety and reliability. You need to check the open source. However, open source vulnerability scan tools have various languages and functions. Therefore, the existing software evaluation criteria are ambiguous and it is difficult to evaluate advantages and weaknesses, so this paper has developed a new evaluation criteria for the vulnerability analysis tools of open source

Purpose - Recently, the importance of rapid change in business models is more and more increasing as the change of information technology environment. Therefore, a variety of business models have emerged. On the other hand, there is no company that can generate revenue. Many enterprises are still maintained while they are changing only their appearance of the business model. Business model is important in e-commerce. However, a lot of researches are targeted only in Web sites. Thus, e-commerce companies do not have the infrastructure for measuring and business models. The purpose of paper is to evaluate factors which are related with the structuring of the e-commerce success. And it proposed a financial items and non-financial items. From the perspectives of administrators and managers, the paper researches the possibility for E-Commerce Evaluation Model as a valuable criteria in measuring business model. Research design, data and methodology - The methods are taken by the classification for the type of business-to-business transactions, transactions subject, and the degree of integration and innovation capabilities. Financial and Non-financial value is used to build E-Commerce Evaluation Model. Evaluation items in Administration's perspective are composed with enhance the effectiveness of the mission, improving efficiency of the administration, and control of costs. Evaluation items in the customer's perspective were measured by customer participation and cooperation with customer Satisfaction. In the case of researching the information system's perspective, three criteria are used such as adequacy of the development process, improvement of the quality of service, and maintenance of standardized information technology. In researching for the ICT competence's perspective, evaluation items were composed of enhanced user capabilities, utilizing new technologies, and empowerment of information workers. Results - In this paper, E-Commerce Evaluation Model with financial and non-financial perspectives shows the possibility to be criteria in the case of measuring business model. Moreover, it gives the positive expectation to be successful criteria. But the research may have ambiguity in its essential concept because it cannot avoid the limitation in selecting evaluation tools from merely the model. It is impossible to exclude the possibility in omitting specific properties which may take place in actual case study. Therefore, In hereafter research, it is necessary to include actual case study research in selecting evaluation tools in order to improve the limit point. Actual measurement items which are derived from actual case study should be subdivided, and it would be more effective to complete the research. Conclusions - In rapid change in business models, there are various kinds of business models. But it is general situation that companies which adopted business models have not brought in revenue. For this reason, E-Commerce Evaluation Model is needed as an important factor for the structuring of the e-commerce success. Although it has the limitation in selecting evaluation tools from model, E-Commerce Evaluation Model proposes the implication for measuring business models as a valuable criteria.

We propose software algorithms which provide the characteristics of acceleration/deceleration essential to high dynamic performance at the transient state where industrial robots or CNC machine tools start and stop. The path error, which is one of the most significant factors in performance evaluation of industrial robots and CNC machine tools, is analyzed for linear, exponential, and parabolic acceleration/deceleration algorithms in case of circular interpolation. The analysis shows that the path error depends on the acceleration/deceleration routine and the servo control system. In experiments, the entire control algorithm including the proposed acceleration/deceleration algorithms is executed on the motion control system with a floating point digital signal processor(DSP) TMS320C30 as a CPU. The experimental results demonstrate that the proposed algorithms are very effective in controlling axes of motion of industrial robots or CNC machine tools with the desired characteristics.
