This paper is a study on the prospects and challenges of Korean language education in the untact(non-face-to-face) era. The COVID-19 pandemic has boosted untact(non-face-to-face) online education. In the future, various types of combined curriculums will be developed and attempted in the field of Korean language education, taking advantage of offline and online education. In addition, along with the development of the edu-tech industry, Korean language education will also achieve great qualitative growth. In particular, the global spread of Korean language and Korean culture (Korean Wave) should be used as an opportunity for Korean language education to be revitalized. In order to achieve this, it is important to clearly recognize the ‘King Sejong Institute’ brand as a starting point for Korean education. Therefore, the establishment of King Sejong Institute and the dispatch of professional teachers should be continued, and a bold investment in the online King Sejong Institute should be made to overcome the limitations of the establishment of King Sejong Institute. It is necessary to strengthen the quality of Korean teachers and revitalize online platforms. By these means it is possible to secure the qualitative growth of Online and Offline Korean language education. (Kyung Hee Cyber University)
1987년 헌법 개정과 이후 개헌 논의의 정치적 상관성
김지형 ( Kim Jihyung ) 아시아문화학술원 2017 인문사회 21 Vol.8 No.5
본 논문은 1987년 제9차 헌법 개정 이후 단속적으로 이어져 온 개헌 논의 현상을 배경으로 하여, 제9차 헌법 개정의 역사적 맥락과 성격 및 특징을 분석하였으며, 이후 형성된 개헌 논의와의 정치적 상관성을 파악하기 위해 작성되었다. 역사적 연구방법론에 따라 1987년 개헌의 원인과 성격을 파악한 결과, 1987년 이후 형성된 제6공화국의 권력 구조는 6월 민주항쟁의 성과에 기인한 체제였음에도 불구하고 신군부의 정권재창출 시나리오가 반영되었을 뿐만 아니라 ‘3김’에게 정치적으로 최적화된 한계가 있음을 확인하였다. 따라서 제6공화국의 권력 구조는 신군부 정권의 연장과 야당 지도자들의 정치권력을 담보하려는 특성에 따라 이어져온 것으로 볼 수 있다. 이 같은 측면에서 향후 개헌 논의는 제6공화국 헌정 구조의 성격과 한계를 이해하고 해소하기 위한 방향에서 전개될 필요가 있다. 또한 시민사회의 적극적인 참여와 국민적 소통뿐만 아니라 미래지향적 민족 생존 및 국가 번영 전략이 새로운 개정 헌법에 반영되어야 할 것이다. This paper were analyzed historical context, characteristics of the ninth amendment of the Constitution In 1987 were analyzed. Also analyzed the content of the constitutional discussion and the discourse about future - oriented values. According to the historical research methodology, it attempted to identify the character according to the cause and background of formation of the constitutional amendment in 1987. As a result, the power structure of the 6th republic under the revised Constitution was attributed to the democratic uprising in June but it reflected scenario to regenerate the regime of the new military authorities and the limitations of the three Kims. Therefore, it can be seen that the 6th republic were fundamentally implied a temporary character created on the constitutional structure to internally accept the extension of the new military regime and the combined oligarchy of opposition leaders. In the future, the revised constitutional debate needs to be developed in order to understand and resolve the character and limitations of this period.

This study presents the estimation of crack depth by analyzing temperatures extracted from thermal images and environmental parameters such as air temperature, air humidity, illumination. The statistics of all acquired features and the correlation coefficient among thermal images and environmental parameters are presented. The concrete crack depths were predicted by four different machine learning models: Multi-Layer Perceptron (MLP), Random Forest (RF), Gradient Boosting (GB), and AdaBoost (AB). The machine learning algorithms are validated by the coefficient of determination, accuracy, and Mean Absolute Percentage Error (MAPE). The AB model had a great performance among the four models due to the non-linearity of features and weak learner aggregation with weights on misclassified data. The maximum depth 11 of the base estimator in the AB model is efficient with high performance with 97.6% of accuracy and 0.07% of MAPE. Feature importances, permutation importance, and partial dependence are analyzed in the AB model. The results show that the marginal effect of air humidity, crack depth, and crack temperature in order is higher than that of the others.

In 2017, since Michelin Guide gave the initial stars to Seoul's 24 fine-dining restaurants, public interest regarding fine-dining restaurant was immediately increased. Among these 24 fine-dining restaurants, majority restaurants are characterized by either Korean, Innovative, Korean contemporary, or French Contemporary restaurants. This initial categorization is too subjective, and the criteria was difficult to understand unless customers had visited the starred restaurants. Therefore, the main purpose this study was to simplify these vague categories and to verify the moderating effect between French and Korean fine-dining restaurants by respondents' choice. The test of two different food types validated that there were 4 significantly different paths between two groups. This multi group analysis provided different strategies for each two different type of fine-dining restaurants. The result indicates crucial variables needed to be carefully focused to attract more customers and make them to revisit.

After the COVID-19 pandemic, Korea’s imported wine market has been rocketing up. At the beginning of the pandemic, Korea‘s wine market had shrunk as well as other counties. However, because of consumer behavior changes such as seeking high quality drinks, home drinking and revenge spending trends, the imported wine market has been writing a new history that this market has never experienced. In fact, Korea wine market was known for the one of matured markets in Asia; therefore no one was expecting such high growth. The purpose of this study is to forecast the size of imported wine market by 2030. And to provide useful information to all related business entities. KITA (Korea International Trade Association)’s 87 time-series data per quarter from Q1 of 2001 to Q3 of 2021 was utilized in this research. The accuracy of model was tested based on value of MAPE. The result of Winters Additive Seasonality Model for the value (MAPE=10.135%) shows that the value size of imported wine market in 2030 will be increased up to USD $1,165,728,000, CAGR=14.38% which is 117% bigger than its size of 2020. On the other hand, the volume of imported wine market (MAPE=9.988%) will be increased up to 92,151,662 tons, CAGR=5.85% which is only 26% bigger than its size of 2020. The result implies that changes of consumer behaviors after the pandemic will dramatically affect entire alcohol market within 10 years. The imported wine consumption is going to occupy over one fifth of total of alcohol market in Korea. And the fine wine market will be increased dominantly as the increase of value is 4.46 times faster than the volume.
