IETF's NETCONF WG has taken efforts in standardizing configuration management protocol, which allows high interoperability of configuration management. In addition to interoperability, high performance is also required in configuration management, but many researches have often discarded the performance aspect of it. In order to fill that void, this paper proposes methods to improve performance with layers of NETCONF. It demonstrates and compares the performance evaluations to verify the efficiency of the proposed methods.

Assessment can be defined as any method used to understand the current knowledge that a student possesses. Assessment may influence decisions about grades, placement, instructional needs, and curriculum. Therefore, the purpose of assessment is to identify how the students think and know, to diagnose the difficulties they face, and to reflect the result of assessment on teaching. But the traditional multiple-choice test failed to evaluate and teach higher-level thinking and problem-solving skills. In this context, performance assessment is being required as an alternative assessment to get better understanding about what the students can do as well as what they know. This article points out some weaknesses of traditional assessments, and comments on the theoretical background and necessity of performance assessment. And it presents more specific information about performance assessment and some examples. It is certain that performance assessment is student-centered and future-oriented. But performance assessment can't be the surest and best way of evaluating the students' abilities. We are just on the way of another experimental stage for improving teaching methodology. More supplementary analyses and further improvements are needed.

Purpose - This study was conducted to identify the impact of teachers' professional development on students' performance. It examines the nature of association between teachers' professional development and students' performance, and analyzes how students can be affected by different factors of teachers' professional development. Research design, data, and methodology - In order to obtain the required goals, Data were randomly collected from 100 students and 45 teachers from three different institutes that are affiliated with KPK Agriculture University, Peshawar. To test the association between teachers' professional development and students' performance, the Chi-square test was applied. Gamma measurement was computed to check the direction of association. Results - The results of the study supported the statement that there exists a positive relationship between teachers' professional development and students' performance. Conclusion - Based on the findings it is surmised that, in order to create a clear learning relationship between teachers and students, management must support the teachers through peer group discussions and training opportunities, and should choose-teachers who can make students pursue the learning of subject knowledge with practical implementation.

To achieve a sustainable competitive advantage, firm is required innovative activities and competences. However, Small and Medium sized Enterprises (SMEs) is hard to achieve a superior performance because they possess low competences. So, this paper identify determinants of innovation performance by firm size in motor and electronics industry based on a resource-based view. This paper analyzes the effects of innovation activities and competence on innovation performance by using firm-level data provided by Korea Innovation Survey (KIS). The empirical evidence presented shows that there are differences of determinants on innovation performance by industry and firm size.

As information technology becomes an increasingly intrinsic part of business operations and it's use has grown more widespread and ingrained, the demand for study on the CIO's leadership increases.. This study was accomplished to analyze the effect that CIO's transformational and transactional leadership have on leadership performance in pursuit of the ideal leadership required of CIO. The study results reveal the followings. First, CIO's transformational. transactional, and laissez faire leadership is statistically related with leadership performance. Especially, the transformational leadership was more correlated with leadership performance than transactional leadership. Second, leadership performance both of transformational leader and transactional leader was higher than than of laissez faire leader. But leadership performance between transformational leadership and transactional leadership was not statistically significant. Third, many CIOs turn out to possess both transformational and transactional leader's trait, and therefore, the subjects were categorized into the three groups such as: purely transformational leaders, purely transactional leaders, and transformational-transactional leaders. The result shows that leadership performance was high in order of transformational-transactional leader, purely transformational leader, and purely transactional leader. It reveals that leaders possessing both transformational and transactional leadership were more acceptable than the others to the subordinates.

In this research, the performance predictions of the submersible mixer were investigated. The variation of the performance characteristics by changing the impeller design parameters were discussed through the flow calculation results by using a commercial program, FLUENT. The performance of the submersible mixers is related to the velocity diffusion profiles downstream of the impeller and also the required input motor power to mix the fluid. In this study, the various design parameters such as the number of blade, the hub and tip diameters, the impeller blade profiles and revolution speed of the blades were taken for the fixed values. The blade sweep direction, the chord length distribution along with the radius of the blade and the inlet blade angle were changed to make different testing models. The flow calculation results show the effect of the changed design parameters on the performance of the submersible mixers and also give some helpful information for designing more efficient submersible mixers.

Recently, the affiliates of the Ministry of Information and Communication have been conducting a performance evaluation study on IT policy projects, based on the performance evaluation model of the U.S. Office of Management and Budgets, with regard to investment in computerization. The performance evaluation model for the policy project could provide the objective information required for the planning, development, and operation of the policy project. However, the performance of the most policy project is likely to be evaluated using the subjective evaluation criteria of evaluators. Therefore, this case study evaluates the relative efficiency using DEA (Data Envelopment Analysis) in order to improve the performance evaluation method of the digital pioneer' project implemented by the Korea IT Industry Promotion Agency. The improvement value of inefficient Decision Making Units (DMUs) was measured by a static efficiency analysis. The measured value will suggest a objective viewpoint of the performance between DMUs to evaluators. In doing so, it will show an appropriate direction for the policy project to be evaluated successfully.
