An efficient molecular breeding technique for coffee plants was developed. In order to produce transgenic coffee plants, we established a model transformation procedure via Agrobacterium method. We isolated a gene encoding a protein possessing 7-methylxanthine methyltransferase (theobromine synthase) activity, and it was designated as Coffea arabica 7-methylxanthine methyl transferase; CaMXMT. Using this clone, we produced transgenic coffee plants, in which the expression of CaMXMT is suppressed by double-stranded RNA interference (RNAi) andlor anti-sense methods. The expression pattern of CaMXMT was analyzed by reverse transcription-PCR method and we found that, in the transformed cell lines, the level of transcripts were obviously suppressed by RNAi. The endogenous level of caffeine in the transformed cells was dramatically reduced in comparison with non-transformed cells.

Students' questions are essential and important for learning, but previous research and experience of instructors shows that there is a lack of interaction between instructors and students in online classes. This research studies how learners can effectively ask questions in online classes at engineering colleges. Based on two axes of anonymity and openness, the four different types of questioning methods were suggested as 'onymous/public', 'onymous/private', 'anonymous/public' and 'anonymous/private.' In this study, seven communication channels were applied to check their effectiveness in an online class. The results showed that learners' satisfaction with learning outcomes increased compared to previous offline classes, while satisfaction with teaching methods was similar. Additionally, among the four types of questioning methods, the preference and effectiveness of 'anonymous/public' was highest, followed by 'onymous/private'. This study suggests several implications of educational approaches to online education in engineering colleges.

Purpose: This study aims to examine the implications of aviation tourism by considering practical and ethical issues in order to achieve academic goals for research ethics. Through this, we intend to derive the direction of research ethics in aviation tourism in the future. Research Design, data and methodology: This study examined ethical issues to examine the current status of research ethics in consideration of the goals of aviation tourism and to analyze and explore the status of research ethics, including various research results and researchers. Results: Aviation tourism is focused on the autonomy of research without strict sanctions. There was a perception that there was no monitoring or control of research ethics, and related scholars did not need to discuss research ethics because the establishment of an academic system was a priority. However, it is now responsible for complying with research ethics limited to integrity and leading research ethics education in domestic aviation tourism. Conclusions: Research ethics problems that may arise in aviation tourism research were explored and issues and tasks were derived. Aviation tourism needs to develop into a more responsible research culture, such as redefining research ethics regulations, changing research culture, and raising researchers' ethical awareness

Background: Malignant melanoma is a cancer that demonstrates rapid progression and atypical clinically features with a poor prognosis. Aim: This study was performed to determine the clinical characteristics and treatment outcomes of patients with malignant melanoma in Turkey. Methods: The medical records of 98 patients between 2007-2012 at our centers were retrieved from the patient registry. Overall survival (OS) was calculated using the Kaplan-Meier method. Results: In our study, with the median follow-up of all patients with cutaneous MM of 46.3 months, the median OS rate of all cases was 43.6 months and 5-year OS was 48.6%. However, five-year OS rates of patients with localized disease (stage I-II) and node involvement (stage III) were 60.3% and 39.6%, respectively. The median OS of stage IV patients was 8.7 months and 1-year OS rate was 26.2%. We showed that advanced stage, male gender, and advanced age in all patients with MM were significant prognostic factors of OS. Conclusions: Compared with the results of current studies from Western countries, we found similar findings concerning demographical features, histological variables and survival analyses for our patients with cutaneous MM in Turkey.

In recent years, coding education has been globally emphasized and the Free Semester System will be executed to the public schools in Korea from 2016. With the introduction of the Free Semester System and the rising demand of Computational Thinking (CT) capacity, this research aims to design 'learning environment' in which learners can design and construct mathematical objects through computers and print them out through 3D printers. Furthermore, it will design learning mathematics by constructing the figurate number patterns from 'soma cubes' in the playing context and connecting those to algebraic and combinatorial patterns, which will allow students to experience mathematical connectivity. It is expected that the activities of designing figurate number patterns suggested in this research will not only strengthen CT capacity in relation to mathematical thinking but also serve as a meaningful program for the Free Semester System in terms of career experience as 3D printers can be widely used.
