I have been asked to remark on the instrumentation which, at least from the viewpoint of the 1980's, seems most important for early implementation on a VLT in the 1990's. To avoid simply making a long list of many possibilities, each of which has some advantage over its competitors, I will divide the discussion into three parts: a summary of the principal observational advances made possible by a VLT in the 15-20 meter class; a list of what is arguably the resulting basic set of needed instruments; and a brief consideration of the telescope design features, technology development programs, and political/financial efforts required to make those instruments a reality.

PurposeThe purpose of this paper is to analyze the determinants of the performance of regional industrial technology development programs among the regional strategic industrial development program that the central government and Daegu metropolitan city jointly promoted between 2004 and 2012. Specifically, in this research, the authors are trying to identify the effects of R&D capabilities and technical development tasks on technological and managerial performance. Design/methodology/approachThe dependent variables of this study are technical and economic performance. Technical performance, product and process innovation, economic performance, sales and export increases were measured using five-point Likert scales. The authors added the contribution of sales through technology development to economic performance. The independent variable is the company’s R&D capability, measured by the number of R&D staff compared to the average total number of employees from 2004 to 2012. The characteristics of the technology development tasks were measured by technical characteristics, market characteristics and collaborative research types. The technological characteristics were measured by seven factors, including technological change, technical difficulty, potential in commercialization, competition between domestic and foreign competitors, difficulty in introducing overseas technology and the technological gap. Market characteristics were largely divided into complexity, dynamics and competitiveness. The types of collaborative research were divided into whether or not there were collaborative research with the participation of large corporations. The control variables are firm size (number of employees) and firm age. Regression analysis was used to analyze the determinants of performance, and a difference analysis was conducted to determine the effect of collaborative research on performance. FindingsThe main determinants of the regional industrial technology development program performance are the characteristics of the technology development task rather than the internal R&D capability; moreover, the technical characteristics, complexity of the developed product market and participation of large corporations had significant effects on R&D capability. The R&D capacity of firms in internal R&D capacity had a significant effect only on the improvement of technology development ability. Therefore, R&D capacity, which is the main determinant of technology innovation, did not have a significant effect on the performance of short-term technology development tasks. Technological change, technological difficulty, competition between domestic and foreign competitors and the technological gap had positive effects on performance, excluding sales contributions. In addition, the complexity of the developed product market such as the diversification of demand, competitive product and sales distribution channels had positive influences on the performance of technology development programs, unlike dynamics and competitiveness. In this study, the authors cannot confirm the effect of collaborative research on the performance of the technology development programs, but they confirmed that collaborative research involving large corporations had a positive influence on performance. Research limitations/implicationsThe results of the analysis of the determinants of regional industrial technology development programs suggest some implications in the future evaluation of these regional industrial technology development programs. It is necessary to review the application qualification and merit, advance review of the business plans and confirmation, an examination of the research results and performance of the applicants and a review of the technology and market situation of the project. For this, the authors suggest that the written review from the relevant technical experts be submitted to the evaluation committees. Also, when establishing regional industrial development programs, they should be evaluated thoroughly, including detailed information and contents about the technical and market characteristics of the local industry. Originality/valueThis research is one of the first to investigate the achievements of R&D support programs among regional industrial development programs in Korea. The results of this study can substantially contribute to the development and implementation of the R&D support policies of the central and local governments. Furthermore, the findings suggest guidelines for improving the performance of R&D support programs in the future. A theoretical model for enhancing the efficiency of government R&D support programs may be established, and an empirical analysis may be conducted to provide practical and academic implications for further research.

The technology development process for the public sector in the transportation industry in South Africa became fragmented as a result of a short-term view with a lack of strategic focus. The subsequent perceived poor performance of the technology development program and inadequate implementation of results motivated the development of a new model for technology development—utilizing a holistic, systems approach at the strategic level with supporting techniques and basic information. The conceptual development of the new technology development model implemented in South Africa is discussed and the use of some of the concepts in the planning and execution of technology development programs for the Southern African Bitumen Association (Sabita) and the South African Department of Transport (SADoT) are illustrated. It is concluded that technology transfer and implementation would be much more effective if it were conducted as part of the technology development system.

Currently, knowledge era is not only concern on books but also technology use as the product to enhance the intellectual capability. This technology development can support the process of teaching and learning English in the classroom activities and language laboratory. Computer and audio visual is the essential media to assist a lecturer, besides books or hand out distributed to the students which also supported the method of teaching according to their needs. In this research, we have observed and analyzed 94 students from the Faculty of Animal Science in two different classes, 46 students in class A and 48 students in class B, year 2014/2015 by using Contextual Teaching and Learning (CTL) system for about one semester. Basically, collaborative materials were given on the scope of Reading, Writing, Listening and Speaking related to animals and their habits by using videos displayed that combined with ONIC DL-300 plus program provided at the English laboratory, Faculty of Animal Science, Udayana University as the supporting element in teaching and learning English. The progress of learning English can be observed and analyzed from their result of evaluation in the classroom and language laboratory. In this case, the result of achievement evaluated from their final scores of soft skill including assignments and participation, practicum, mid test and also final test. It showed that 100% students passed the final range scoring in class A and 96% students passed in class B.

For at least the next decade, as in the recent past, the materials and process area will assume a major role in the advancement of the propulsion gas turbine industry. The selection of promising material and process technologies, with highest payoff at lowest technical and financial risk, is a major challenge. Technology development programs undertaken in the laboratory are selected, based on design needs, compatibility with payoffs in specific and generic applications, and facilities requirements. Advanced materials and process technology efforts for exploitation include directional superalloys for turbine airfoils, clean superalloy blisk/disk materials, gas path seals for clearance control, thermal barrier coatings for airfoils and hybrid structures, composite materials, and rapidly solidified plasma deposited structures. These developments will contribute significantly to the major thrusts of performance improvement, weight reduction, reliability and life extension, and reduced initial ownership cost.
