This paper reviews the Korean government’s selection process of core wireless communications technologies, and presents technology trends, perspectives and strategies of 5 core technologies to develop in wireless communications areas based on the mid term IT technology development plan(2002∼2004). Delphi Panel Method and Analytic Hierarchy Process(AHP) Analysis were adapted to select 30 core technologies in 9 strategic areas. Especially, 5 core wireless communications technologies out of 24 required technologies are selected: 4 G Core Technology, Broadband Wireless Access Network Technology, IMT-2000 Plus STP Technology, OBP Based Multimedia Satellite Communications Technology, Stratosphere Communications System Technology. Strategic national IT R&D program has been essential to continue success story of CDMA technology, and acquiring technology independency from advanced nations. In long term perspectives, a strategy of intensive investment with prudent selection onto core technologies should be deployed in the IT R&D programs. Also, the national IT R&D programs should be limited in the high risk & high returen areas where only government can afford the failures as well as better spill over effects are expected for the technology development and national economy. Korean industry has some strength in wireless communications technology area. Therefore, more policy concerns should be given into this area not only to secure present strength but also to explore better technology competitiveness.

Bioequivalence is a term in pharmacokinetics used to access the expected in vivo biological equivalence of two proprietary preparations of a drug. Bioequivalence studies are usually performed for generic drugs. Two pharmaceutical products are bioequivalent if they are pharmaceutically equivalent and their bioavailabilioes after administration in the same molar dose are similar. Bioequivalence is usually accessed by single dose in vivo studies in healthy volunteers and the reference product is usually the innovator product that is marketed. Regulatory definition of bioequivalence is based on the statistical analysis of thebioavailability of the reference and test product. In general, two products are evaluated as bioequivalent if the 90% confidence interval of the relative mean Cmaxand AUC of the test to reference product are within 80.00% to 125.00% in the fasting state. Key process in bioequivalence study is development and validation of bioanalytical method, determination of the drug concentration in the biosamples (usually plasma or serum) obtained from volunteers, calculation of the pharmacokinetic parameters and statistical analysis of the pharmacokinetic parameters. Although current guidelines and regulations do not require the bioequivalence studies to be done under good laboratory practice (CLP), the issues to perform the bioequivalence studies under GLP environment is emerged both from the regulatory and industry side. GLP perspectives of bioequivalence studiesare needed to be discussed in respect to achieve quality assurance in bioequivalence studies.

The aims of this study was to investigate environmental views of national park rangers and their perspectives on natural environment interpretation as managers and to provide a basic resource to make programs regarding natural environment interpretation improve. The specially designed questionnaire was administered to twenty-five national park rangers who had worked at the southern office of Jiri Mountain National Park. Analysis results are as follows. They had have concerns with environmental problems and about preservation of natural environment. Most of them thought that the purpose of natural environment interpretation was to make change regarding public perceptions and attitudes toward natural environment. Over sixty percents of them recognized that publics had rarely participated in the natural environment interpretation program prepared by a national park. It was turned out that public had not concerned with the program because of the lack of their interests and recognitions regarding the natural environment interpretation program due to the lack of active advertisement for it. It is expected that national park rangers need to advertise the necessity of the program and to manage the program effective with more active mind as well as to develop and practice more appropriate programs for natural environment interpretation.

The College of engineering's capstone design is student-team-centred learning based on project-based learning and is one of the most important courses for students aiming to be competent professional engineers capable of solving real industrial problems. Therefore, in order to resolve the capstone problems, various face-to-face contacts such as frequent industrial site visits, multiple meetings with diverse people including team members, and repeated contacts with course-supervising and team-advising professors are prerequisite processes. However, according to the transition to fully online education due to the global pandemic of COVID-19, capstone design courses for 2020 and 2021 were also conducted online. Based on the modified students' evaluations of educational quality (SEEQ) with 3 perspectives such as curriculum, teaching-staff and students themselves, this study compares their evaluations of offline capstone designs from 2013 to 2019 and online capstone designs in 2020 and 2021 in the context of COVID-19. In 3 perspectives, the difference in students' evaluation of the online capstone between the beginning and the end of the course shows a positive effect, which is better than the offline capstone. Also, in various dimensions for each perspective, the online capstone shows a better evaluation than the offline capstone. These findings suggest that the online capstone design curriculum can be expected to have educational effects as well as students' satisfaction with the online curriculum in the future.

Purpose: In the era of sustainable development, the role of consumers and businesses has become increasingly important by demonstrating the importance of social and environmental issues. Accordingly, firms widely adopt cause-related marketing to fulfil corporate social responsibility. The purpose of this study is to examine factors that affect consumer attitude toward cause-related marketing with perspectives of the sustainable development goals (SDGs) and instrumental conditioning. Research design, data and methodology: Proposed research questions include effects of cognition, emotion, sustainability, and business ethics on attitude, effects of attitude on purchase intention, and effects of intention on satisfaction. This study collected the data via an online survey and applied factor and regression analysis. Results: Findings indicated that factors affect attitudes differently in cases of cause-related marketing with SDGs and instrumental conditioning. The results of this study found that business ethics affects consumer attitude and differ based on types of cause-related marketing. This study found that attitude positively affects purchase intention that also affects expected satisfaction. Conclusions: By applying perspectives of SDGs, findings of this study provide implications to producers, marketers, and policymakers to promote and achieve sustainability. In particular, the results found that business ethics should be more addressed to fulfill customer attitude.
