Advanced process and integration for future semiconductor devices is approaching the physical limit. The new materials with low dimensional structure have recently attracted great attention due to its expandability for the future electronic devices. In order to apply the materials to future semiconductor devices, the control of carrier scattering is critical issue. That is, the carrier scattering with physical quantity in low dimensional structure significantly modulates the device characteristics. We introduce the role of defect in several future semiconductor materials and devices. The analysis of defect in the structure becomes the most important techniques. In particular, surface defect in nano structures totally controls the device characteristics. The changes imply that the metrology field is leading the future industry for semiconductor.

The purpose of this study is to provide basic data for developing future ethics education programs by surveying healthcare providers working at institutions of various sizes, using Ethical Issues in Clinical Practice tool. Data were collected from 149 healthcare providers working at medical institutions in G-do. Analysis was done using t-test, ANOVA, Pearson correlation coefficient, and Multiple regression with IBM SPSS WIN/21.0. Needs for ethics education was inversely correlated to end-of-life treatment issues (r=-.22, p=.007) and patient care issues (r=-.28, p<.001). The most influential factor on the subjects' needs for ethics education was patient care issues (β=-.246, p=.035), followed by Buddhism (β=.208, p=.010). The explanatory power was 13.4% (F=5.596, p<.001). Therefore, when organizing the contents of ethics education program, patient care issues should be included to meet the needs of the subjects. Also, a customized program regarding the subjects' religion is necessary.

Aspects of the current trend in lubricants and future challenges are discussed. The discussion highlights key enviromnental issues regarding to resource conservation, toxicological consideration and environmental acceptability. Also highlighted are base stocks trends relative to hydroprocessed stocks (HVI, VHQ and XHQ), synthetic base stocks (PAO and organic esters) and biodegradable fluids (vegetable oils and special esters). Equipment severity and lubricant performance quality are briefly described.

This paper will review the state of the latest development of AMLCD manufacturing facilities for large Substrate and discuss the future technologies. The trend of the display size enlargement of Note book PC has hauled the enlargement of the mother glass substrate in past 10 years. The enlargement of a substrate size has brought about the productivity improvement of the TFT panel with process innovation as yet. Will this trend be continuing hereafter too? The issues of the processing and facilities related with the large square substrate and mask step reduction will be overviewed and the future processing and facilities will be discussed.

Technological, policy and economic factors are both important variables in maximizing the results of a national R&D program and key indicators in evaluating an R&D program's eligibility for financial support. Economic analysis, in particular, is used when selecting R&D programs, setting priorities, and estimating economic effects. This paper examines a series of methodological issues related to the economic analysis of national R&D programs within the framework of the current preliminary feasibility evaluation system, and proposes alternative approaches to each of the issues discussed. The issues include the definition of R&D valuation and establishment of valuation factors; estimation of sales attributable to R&D investment; assessment of the total economic value of R&D as intellectual assets; estimation of R&D benefits and assumption of related to sales; and the application of discount rates based on the weighted average cost of capital. Finally, this study presents directions for future research on analytical procedures and methods of improving the reliability of the results of economic analysis within the national technology planning system.

This paper reviews and identifies issues in the application of virtual commissioning technology for automated manufacturing systems. While the real commissioning of a manufacturing system involves a real plant system and a real controller, the virtual commissioning deals with a virtual plant model and a real controller. The expected benefits of virtual commissioning are the reduction of debugging and correction efforts during the subsequent real commissioning stage. However, it requires a virtual plant model and hence still requires significant amount time and efforts. Two main issues are identified, the physical model construction of a virtual device, and the logical model construction of a virtual device. This paper reviews the current literature related to the two issues and proposes future research directions to achieve the full utilization of virtual commissioning technology.

We introduce an introductory engineering education course for engineering majors and non-engineering majors. This course does not require any previous knowledge and experience on engineering. It requires strong curiosities and imaginations on current and future society we live in, where technology is inseparable ingredient. Course encourages attendees to explore fundamental issues of engineering: what is proper technology and what are proper ways of exercising engineering, issues dealt in soft engineering. Since course topics cover many aspects of technology, traditional learning methods fail to be successful and efficient. Various efficient learning methods have been proposed and implemented. We utilize various interactive tangible media, which include simulated thought experiments and physical media experiences. About 20 episodes in short film format are produced based on scenario written according to related issues selected. Physical media like interactive robots are introduced for attendees' stimulated experiences. We summarize our exciting experiments on interactive teaching experiences at Pusan National University which include on/off-line interactions, assignments, projects, and evaluations.

In a rapidly changing and increasingly technological society. the use of technology should not be disregarded in issues of learning algebra. The use of technology in learning algebra raises many learning and pedagogical issues. In this article, previous research on the use of technology in learning algebra is synthesized on the basis of the four issues: conceptual understanding, skills, instrumental genesis, and transparency. Finally, suggestions for future research into technological pedagogical content knowledge (TPCK) are made.
