본 논문에서는 딥러닝 모델 중 Keras 기반 LSTM 모델과 KoGPT-2 모델을 이용하여 학습한 결과를 바탕으로 카테고리 별 키워드 기반의 배달 음식점 리뷰를 생성하는 방법을 제안한다. 데이터는 주로 맛, 양, 배달, 가격으로 구성되어 있으며 이를 카테고리 별로 구분하였다. 또한 새롭게 생성된 텍스트는 의미와 문맥을 판단하여 기존 리뷰 데이터와 비슷하게 구현하였다. 모델마다 성능을 비교하기 위해 정량적, 정성적 평가를 진행하였다.

This article discusses the contributions of the leader Oswald Veblen, who was the president of AMS during 1923-1924. In 2006, Korea ranked 12th in SCIE publications in mathematics, more than doubling its publications in less than 10 years, a successful model for a country with relatively short history of modern mathematical research. Now there are 192 four-year universities in Korea. Some 42 of these universities have Ph.D. granting graduate programs in mathematics and/or mathematical education in Korea. Rapid growth is observed over a broad spectrum including a phenomenal performance surge in International Mathematical Olympiad. Western mathematics was first introduced in Korea in the 17th century, but real significant mathematical contributions by Korean mathematicians in modern mathematics were not much known yet to the world. Surprisingly there is no Korean mathematician who could be found in MaC Tutor History Birthplace Map. We are at the time, to have a clear vision and leadership for the 21st century. Even with the above achievement, Korean mathematical community has had obstacles in funding. Many people thinks that mathematical research can be done without funding rather unlike other science subjects, even though they agree fundamental mathematical research is very important. We found that the experience of early American mathematical community can help us to give a vision and role model for Korean mathematical community. When we read the AMS Notice article 'The Vision, Insight, and Influence of Oswald Veblen' by Steve Batterson, it answers many of our questions on the development of American mathematics in early 20th century. We would like to share the story and analyze its meaning for the development of Korean Mathematics of 21st century.

The interests of education methods using Serious games have been increasing recently. But resu,lt-oriented game design framework have not been reflected intrinsic motivation. To increase usage of educational serious game as resource, it is needed game design framework for providing the immersion and collaborative active learning that cognitive Psychologic theories recommend. By outlining the background of the serious game design framework and exemplifying its use, a constructive structure to examine purposed based games is introduced.

This review paper presents an introduction of contact mechanics and rubber friction theory for sliding friction of elastomer composites in contact with rough surfaces. Particularly, Klüppel & Heinrich theory considers the self-affine (or fractal) characteristic for rough surfaces to predict adhesion and hysteresis frictions of elastomers based on the contact mechanics of Greenwood & Williamson. Due to dynamic excitation process of elastomer composites while sliding in contact with multiscale surface roughness (or asperity), viscoelastic properties in a wide frequency range becomes major contributor to friction behaviors. A brief description and examples are provided to construct a viscoelastic master curve considering nonlinear viscoelasticity of elastomer composites. Finally, application of rubber friction theory to tire tread compounds in traction with road surfaces is discussed with several experimental and theoretical results.
