The purpose of this study was to identify the current status of ethics education in science and technology for pre-service science teachers and find out their recognition on the needs for ethics education at school. A survey was administered for this study and a total of 594 pre-service science teachers studying in college/university of education participated. The survey was organized to examine participants' 1) experience in ethics education in science and technology, 2) recognition on the needs of ethics education in science and technology, and 3) the need for it in elementary and secondary school. Each item was responded using either 1 to 5 Likert type scale, multiple choices, or open questionnaires. The results showed that 37.4% of participants obtain science technology information from the mass media, and 23.5% from the school education. Only 8.4% of the participants had the experience of taking class on ethics in science and technology. In terms of level of confidence in understanding the ethical issues in science and technology, the average response was 2.73. However, their perception on the needs of the ethics education ranges from 3.34 to 4.58, which is much stronger than other responses on average. This strong perception on the needs was much higher for pre-service science teachers for elementary school, than those of the secondary school(p<.05). All participants recognized the need for ethics education in science and technology at both elementary and secondary school. In responses for which subject should provide ethical issues on science and technology, science class was most frequently suggested (62.4%), followed by ethics class (29.1%). In responses for the most efficient form of learning, they suggested that case studies (43.5%), followed by discussions (41.4%) would be an efficient way to learn. Even in the responses of open questionnaires asking for efficient ways of learning ethical issues, participants suggested that discussions on various ethical issues on the cases in the science and technology would provide practical and substantial learning.

Science-Technology-Society curricula have been developed in several countries for the last 20 years. Those curricula were focused on social aspects of science, i.e., value-laden knowledge and scientific enterprise, and society-related scientific and technological issues, i.e., energy, pollution, natural resources. The major teaching models employed in those curricula were problem solving and decision making, which required the following teaching techniques: teacher as a manager, small group discussion, controversy as a motivational force for substantive learning, and sufficient factual information into the discussion. Further researches are to be made to ascertain whether or not the expectations of the curricula might be realized in practice. It was shown that most Korean biology teachers considered the STS-related goal of science education as more important than the other goals. Based upon the findings, some recommendations for development of Korean STS curriculum were made as follows: 1. The contents of the STS curricula are to be organized with the integrated mode; 2. The major teaching models throughout the contents are to be problem solving and decision making. These are considered to provide students with the opportunities to involve in debates on practical issues and to draw consensus from them; 3. Some degree of flexibility should be provided on teachers' implementation of the curriculum in terms of contents, teaching techniques etc.; 4. To increase the practicality of the curriculum, teachers should be involved in the development of the curriculum and the relevant research; and 5. Contents to be included in STS curriculum were suggested by some science educators, but the more systematic study is required in this respect.

With the exponentially increasing Internet traffic and emergence of more versatile and heterogeneous applications, the design of datacenter networks (DCNs) is subject to unprecedented requirements for larger capacity and more flexible switching granularities. Envisioning Optical-Orthogonal Frequency Division Multiplexing (O-OFDM) as a promising candidate for such a scenario, we motivate the use of O-OFDM as the underlying switching technology in order to provide sufficient switching capacity and elastic bandwidth allocation. For this purpose, this article reviews the recent progresses of DCN deployment and assesses the scenario where the O-OFDM transmission and switching technology is employed in the underlying transport plane. We discuss the key issues of the datacenter-oriented O-OFDM optical networks, and in particular, elaborate on a number of open issues and solutions including system interconnection architecture, routing and resource assignment, survivability, and energy-efficiency.

The ubiquitous technology, leading the stream of change in telecommunication market, makes VoIP a foundation technology to enter NGN era. With this trend in mind, VoIP providers try to satisfy customer needs and invest on R&D in order to survive in this emerging market. The critical issues to VoIP providers are two fold the first one is to find out the quality attributes of Internet telephony service; and the second one is to assess the impact they have on customer satisfaction, customer loyalty and customer performance. In this study, we attempt to empirically answer the above two issues employing SEM (structural equation modeling) and AHP (analytic hierarchy process), and suggest strategic guidelines for successful deployment of Internet telephony service.

Pharmaceuticals require more detailed packaging than do other sensitive products, such as foods, although there are several similarities in their requirements. Because the required action of a medication can be nullified by any deterioration in its active principles the protection required from its packaging is at least an order of magnitude greater than that needed by foods. Therefore, security and integrity of the package are more important and are controlled by licensing arrangements. To achieve levels of safety, reliability, and quality, pharmaceutical firms must identify and correct potential problems with packaging functions. Purpose of this study is to identify the present issues pharmaceutical packaging and to forecast their future for the development of pharmaceutical packaging.

Recently many companies began to realize their visions for the sustainable growth with the advent of CSV(Creating Shared Values). Michael E. Porter, a Harvard Professor, claims that placing social value creation at the core of business strategy has the potential to uncover big opportunities for individual companies and that shared value can play a significant role in increasing competitive advantages while fostering social prosperity. In consequence, the various researches have illustrated how to get the opportunity for competitive advantages from building a social value proposition into corporate strategy, and considerable studies have been promoted heavily from the managerial perspective. However, due to the lack of capability converging information technology with business strategy, any research effort to identify technological or Internet-related issues and to link the issues to CSV does not exist. With Korean being a Internet leading country, the demands of researches analyzing core technology, information, and service utilizing Internet are rapidly growing. The study aims to find out Internet-related enablers for CSV. This paper describes the concepts and features of CSV, identifies emerging Internet-related issues toward the opportunity for competitive advantage, and then depicts the rigorous research endeavors in the areas of Internet information, technology, and services. As a result, 11 papers presented and selected as the outstanding papers at APIC-IST 2014 handle the issues to be brought together, which include: Wireless and Sensor Network, Image Processing and HCI, Big Data and Business Intelligence, Security & Privacy in Internet, SNS & Communication, Smart-Learning and e-Learning, and Internet Business Strategy. The study finally recommends indispensible terms for substantially vitalizing CSV.

In this paper, we motivate the post-mask performance enhancement technique combined with the Multi-Threshold Voltage CMOS (MTCMOS) leakage current suppression technology, and integrate the new design issues related to the MTCMOS technology into the ASIC design methodology. The issues include short-circuit current and sneak leakage current prevention. Towards validating the proposed techniques, a Personal Digital Assistant (PDA) processor has been implemented using the methodology, and a 0.18um process. The fabricated PDA processor operates at 333MHz which has been improved about 23% at no additional cost of redesign and masks, and consumes about 2uW of standby mode leakage power which could have been three orders of magnitude larger if the MTCMOS technology was not applied.
