Recently, there is an increasing need to produce more precise products with small deviations from defined target values. Machine capability is the ability of a machine tool to produce parts within a tolerance interval. Capability indices are a statistical way of describing how well a product is machined compared to defined target values and tolerances. Today, there is no standardized way to acquire a machine capability value. This paper describes a method for evaluating machine capability indices in machining centers. After the machining of specimens, the straightness, roundness, and positioning accuracy were measured by using CMM (coordinate measuring machine). These measured values and defined tolerances were used to evaluate the machine capability indices. It will be useful for the industry to have standardized ways to choose and calculate machine capability indices.

In the knowledge-based economy, technological capability is critical for the survival and growth of firms. Technological capability differs across firms depending on the structural and environmental conditions. In nature, the evaluation of technological capability is an intractable task and thus previous studies often employ such proxy measures as patent, productivity, or profitability. In this research, we define technological capability as a combination of the above three measures and investigate, by using the multi-variate statistical analysis, the characteristics of technological capability of electronics/IT firms of Korea. We first propose a taxonomy in which firms are classified into four clusters based on the differences in the nature of technological capability. Then, across clusters, we comparatively analyze the relationship between technological capability and structural/environmental factors of firms. Finally, the implications of empirical findings will be discussed. This study is a small-scale, descriptive one but will be extended and elaborated by augmenting the database and/or incorporating more variables.

데이터베이스 시스템은 웹의 발달과 함께 웹 데이터베이스라는 새로운 단계로 진화하고 있다. 웹 데이터베이스에서는 다양한 데이터 소스의 통합이 가장 큰 이슈로 미디에이터에서 각 래퍼가 가져온 스키마를 통합하는 작업을 수행한다. 미디에이터에서는 이와 같이 데이터 소수의 통합 외에 사용자에게 질의를 각 데이터 소스에 대하여 재작성 하는 기능이 중요하고 이에 대한 다양한 연구가 진행 중이다. 이때 질의를 각 소스가 처리할 수 있는 부질의로 재작성 할 때 필요한 개념이 capability이다. 본 논문에서는 capability를 기반으로 한 질의 시스템에서 사용자에게 제공되는 뷰와 질의에 대해서도 capability를 적용한 사용자 기반 capability 기법을 제안한다. 지금까지 타 연구에서는 소스에 대한 capability만을 고려하여 질의를 재작성 하였지만 본 논문에서는 사용자 기반의 capability를 함께 고려함으로써 사용자 요구사항을 충족시키면서도 비교적 간단한 분석과 매칭 과정에 의해 컴파일 시간 내에 계산이 가능하도록 하는 알고리즘을 제시한다. 또한 네트워크의 문제 등으로 인해 소스 중 일부분이 사용할 수 없는 상황인 경우 소스에 대해 active selection이 가능하도록 하여 대체 질의를 생성할 수 있게 하였다. 간단한 구현과 제시한 기법이 비용을 절감하는 실제적인 방법이며 타 연구와의 비교를 통해 좋은 성능을 가짐을 보인다.

The Available Transfer Capability (ATC) is defined as the measure of the transfer capability remaining in the physical transmission network for further commercial activity above already committed uses. Available Transfer Capability (ATC) calculation is a complicated task, which involves the determination I of total transfer capability (TTC), transmission reliability margin (TRM) and capability benefit margin (CBM). As the electrical power industry is restructured and the electrical power exchange is updated per hour, it is important to accurately and rapidly quantify the available transfer capability (ATC) of the transmission system. In ATC calculation,. the existing CPF method is accurate but it has long calculation time. On the contrary, the method using PTDF is fast but it has relatively a considerable error. This paper proposed QFA method, which can reduce calculation time comparing with CPF method and has few errors in ATC calculation. It proved that the method can calculate ATC more fast and accurately in case study using IEEE 24 bus RTS.

This research proposed the necessary capability of cyber security professional personnel for cyber security education and training. Cyber security professional personnel were required specialized capability because the curriculum of cyber security education and training is structured around practice and training. Based on the knowledge, skills, and attitudes of professors, we derive candidate capabilities and index through the results of precedent research. As a result, we derived capability such the candidate capability group as teaching qualification, expert knowledge, practical ability, lecture ability, and research ability, and detailed capability index was derived accordingly. Finally, based on the questionnaire results of the professors related to the information security, it was determined that the capability required for the cyber security education and training professional personnel were expert knowledge, practical ability, and lecture ability. Among the capabilities, executive ability means that they have to fulfil abundant executive experience due to the high proportion of practical training due to the characteristics of cyber security education and training.

This study has attempted to empirically analyze the mediating effects of small and medium venture firms' manufacturing capability and testing and inspection capability on the relation between their external information network heterogeneity and technology commercialization capability with a view to diversifying the research stream on the influential factors to small and medium firms' technology commercialization capability. By performing the ordinary least squares regression analysis, the Sobel test, and the Baron and Kenny test based on the 683 data of South Korean small and medium venture firms with the IBM SPSS version 23, this study provides the three empirical findings to be useful for future studies on the roles of small and medium venture firms' the manufacturing capability and testing and inspection capability. First, small and medium venture firms' manufacturing capability partially mediates the positive effect of their external information network heterogeneity on their technology commercialization capability. Second, their testing and inspection capability partially mediates this positive effect. Third, their manufacturing capability and testing and inspection capability jointly and partially mediates this positive effect.

As job market squeezes and more institutions have been requiring NCS(National Competency Standards) based recruitment, the importance of NCS has been growing. Among the 10 domains of NCS, the most relevant one with task processing and organizational performance filed is 'task processing capability group', which is becoming more important with the advent of the fourth industrial revolution era. The purpose of this study is to investigate the effect of college students' task processing capability group on their career outcome expectation and career preparation behavior. In this study, we set up a process model to comprehend the effect of college students' task processing capability group on career outcome expectation and career preparation behavior based on social cognitive career theory. Empirical analysis showed that task processing capability group(problem-solving capability, information capability, resource management capability, organizational capability) positively influenced college students' career outcome expectation and career preparation behavior for employment. However, the impact of technical capability on career outcome expectation and career preparation behavior was not explained. In order to strengthen the task processing capability group of college students, not only university-level efforts, but also college and faculty's efforts should be accompanied. Other academic and practical implications are discussed.

Previous researches have been conducted on the drivers of alliance performance up to date. Unlike existing literatures, we examine the influence of alliance management capability as direct drivers on venture's alliance performance. Based upon organizational capability theory, we proposed that coordination capability, relationship capability, learning capability are main components of alliance management capabilities. In addition, we proposed capability of CEO as forth alliance management capability in global ventures. Using 78 global ventures as research sample, this study shows that these four alliance capabilities have considerable influence on financial performance of ventures with global alliances.
