This study designs and conducts Introduction to Japanese classes for novice learners in Japanese based on the Task-based Language Teaching method, a communication-centered teaching method, and Focus on Form Theory. In the existing lecture type classes, the students did not have the opportunity to use Japanese and eventually stopped learning Japanese. In Japanese classes that has implemented the Task-based Language Teaching method and the Focus on Form, the goal is to properly use the Japanese that has been learned. The first step of the study organizes the meaningful parts in the Communication Centered Teaching Method and FonF study for novice Japanese learners. Next, by using FonF and TBLT, classes are conducted in order to develop communicative competence for novice learners. The results of the study examines the class satisfaction survey completed by the learners. In the psychological section of the learners, there was a positive effect in the Task activities classes, and this has also positively affected the learning experience for the target language. Classes that utilized tasks provided more opportunities to use Japanese, and also successful experiences in learning Japanese had increased which led to high motivations in learning Japanese. Furthermore, tasks that were highly applicable to daily life allowed students to learn more meaningful and practical Japanese.

The purpose of this study is to measure and demonstrate the orality score for expression items in Korean grammar education. Accordingly, a total of 176 expression items were extracted from two copies of a Korean grammar dictionary, and the frequencies in the written and oral corpus were analyzed. Based on this, the orality score (G²) was calculated. As a result of evaluating the orality score, a total of 36 expression items were found to have colloquialism. A standard for grading orality scores was arranged, and the spoken expression items were graded accordingly. Furthermore, a method for visualizing these results was presented. The results of this study are significant in that they can be used as materials for teaching and learning Korean grammar, explaining grammar, and discriminating between spoken and written errors.

The prevalence of metabolic syndrome (MetS) and its cost are increasing due to lifestyle changes and aging. This study aimed to develop a deep neural network model for prediction and classification of MetS according to nutrient intake and other MetS-related factors. This study included 17,848 individuals aged 40–69 years from the Korea National Health and Nutrition Examination Survey (2013–2018). We set MetS (3–5 risk factors present) as the dependent variable and 52 MetS-related factors and nutrient intake variables as independent variables in a regression analysis. The analysis compared and analyzed model accuracy, precision and recall by conventional logistic regression, machine learning-based logistic regression and deep learning. The accuracy of train data was 81.2089, and the accuracy of test data was 81.1485 in a MetS classification and prediction model developed in this study. These accuracies were higher than those obtained by conventional logistic regression or machine learning-based logistic regression. Precision, recall, and F1-score also showed the high accuracy in the deep learning model. Blood alanine aminotransferase (β = 12.2035) level showed the highest regression coefficient followed by blood aspartate aminotransferase (β = 11.771) level, waist circumference (β = 10.8555), body mass index (β = 10.3842), and blood glycated hemoglobin (β = 10.1802) level. Fats (cholesterol [β = −2.0545] and saturated fatty acid [β = −2.0483]) showed high regression coefficients among nutrient intakes. The deep learning model for classification and prediction on MetS showed a higher accuracy than conventional logistic regression or machine learning-based logistic regression.

Hyerim Han,Bo Young Han,Yeong Jin Chung,Sang Chul Shin 한국식물병리학회 2008 Plant Pathology Journal Vol.24 No.2

Accurate identification of pine wood nematode, Bursaphelenchus xylophilus is a prerequisite to diagnose the pine wilt disease. However, a fungivorous nematode, B. mucronatus is highly similar to B. xylophilus and it is difficult to differentiate these two species by morphological features. A molecular diagnosis method, ITSRFLP was applied for the identification of B. xylophilus and B. mucronatus from Korea. Genomic DNA was extracted from a single individual nematode and ITS DNA was amplified by PCR. The size of PCR product was approximately 900 bp and the sequence data were obtained after cloning. Amplified ITS was digested by 5 different restriction enzymes (Rsa I, Hae III, Msp I, Hinf I, and Alu I) and provided a discriminatory profile for B. xylophilus and B. mucronatus. Besides, B. mucro- natus was determined to have 2 different genotypes, East Asian type and European type also clearly separated by Rsa I and Hae III digestion. European type of B. mucronatus is recently collected from Pinus koraiensis and has not been reported before. ITS sequnce data were analyzed by Restriction Mapper program and the result supported ITS-RFLP pattern. These data indicated that PCRRFLP method is an accurate and simple way for identification of Bursaphelenchus species.

Hyerim Lee,Yoye Yu,Hee-Jong Koh 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07

Leaves are the organ for photosynthesis, respiration and transpiration, and have a major effect on crop yield. Therefore, leaf shape and structure are important agronomic traits in breeding for ideal type plant. We obtained a new abaxially rolled leaf mutant from Ilpum(Oryza sativa ssp. japonica) by the treatment of ethyl methane sulfonate(EMS). The abaxially rolled leaf mutant showed reduced plant height and panicle length, increased tiller number and panicle number than Ilpum. LRI(Leaf rolling index) analysis showed that the mutant have high value compared to the wild-type. In cross section analysis, the mutant was observed to have increased of bulliform cell number and size, and led to the outcurved leaf rolling. The phenotypes of the F1 plants derived from the cross between the mutant and Ilpum were normal. In F2 population, segregation ratio between the wild type and the mutant was 3:1. This genetic analysis indicated that leaf rolling is controlled by single recessive gene. Bulked segregant analysis(BSA) and genetic mapping were conducted using F2 population derived from the cross between mutant and Milyang23(Oryza sativa ssp. indica). According to the results, the gene was located on the long arm of chromosome2. Fine mapping is in progress.
