Although Korea students have been showed the top academic achievement in the international evaluation test for mathematics academic achievement, they have the low confidence, low interest and unwelcome attention about mathematics. In order to change student's affective aspects about mathematics, we introduced the problem based learning(PBL) method which is based on constructivist learning theories. By applying PBL to the middle and high class students, we investigated the effect of PBL on the students' academic achievement and mathematical attitudes. The study shows that there are the statistically significant differences between a control group and a comparison group both in academic achievement and mathematical attitudes.

The Korean government strives to transform the society from one that stresses academic and qualification to one that stresses individual competencies. National Competency Standards(NCS) has been adopted to this end. However, NCS classifies cadastre into a group with survey and spatial information collection. Such classification limits cadastre to encompass cadastral administration, cadastral survey, geospatial survey, etc. This study reviews current status and implications of NCS, and proposes few solutions: improvement of classification system, introduction of cadastral industry cooperation model, curriculum development based on competency level, unification between NCS developer and learning module writing group, etc.

The purpose of this study is to explore the main characteristics regarding of implicating competence-based curriculum in Finland's home economics curriculum by analyzing curriculum documents and related literature. The research findings are categorized into four main characteristics. First, home economics in Finland belongs to the 7-9 grades. The key content areas are composed of 'food knowledge & skills and food culture', 'housing & living together' and 'consumer & financial skills' at an integrated approach. Secondly, the subject competences of home economics are not presented; however, the general objectives of transversal competences are defined in Finland's curriculum document. Transversal competences describe the aspects of the objectives that are emphasized in grades 7-9 and strengthens the connectivity with each subject. Thirdly, the objectives of home economics included in the instructions in Finland consist of a content system that links learning skills, content areas, and transversal competences. Both learning skills as a role of subject competences and content areas as objectives support teachers who restructure an curriculum. Fourth, in terms of achieving subject objectives, the assessment criteria in Finland home economics is to evaluate the achievement of good knowledge and skills through actual performance. Based on the research findings, the main features of the revised curriculum in Finland include encouragement of flexibility in education systems and learner's uniqueness in schools. If the implementation of subject competences in home economics is to be strengthened, it is necessary to intergrate the knowledge and competence, require a curriculum system for implements' subject competence, carryout assessment as learning to learn, and facilitate school community and teacher community for deeper co-operation.

The TATI model is a Traffic Accident Text to RGB Image model, which is a methodology proposed in this paper for predicting the severity of traffic accidents. Traffic fatalities are decreasing every year, but they are among the low in the OECD members. Many studies have been conducted to reduce the death rate of traffic accidents, and among them, studies have been steadily conducted to reduce the incidence and mortality rate by predicting the severity of traffic accidents. In this regard, research has recently been active to predict the severity of traffic accidents by utilizing statistical models and deep learning models. In this paper, traffic accident dataset is converted to color images to predict the severity of traffic accidents, and this is done via CNN models. For performance comparison, we experiment that train the same data and compare the prediction results with the proposed model and other models. Through 10 experiments, we compare the accuracy and error range of four deep learning models. Experimental results show that the accuracy of the proposed model was the highest at 0.85, and the second lowest error range at 0.03 was shown to confirm the superiority of the performance.

Half of the world's total population lives in cities, continuous urbanization is progressing, and the urban population is expected to exceed two-thirds of the total population by 2050. To resolve this phenomenon, the Korean government is focusing on building a new urban air mobility (UAM) industrial ecosystem. Airlines are also part of the UAM industry ecosystem and are preparing to improve efficiency in safe operations, passenger safety, aircraft operation efficiency, and punctuality. This study performs demand forecasting using time series data on the number of daily passengers on Korean Air's Gimpo to Jeju route from 2019 to 2023. For this purpose, statistical and machine learning models such as SARIMA, Prophet, CatBoost, and Random Forest are applied. Methods for effectively capturing passenger demand patterns were evaluated through various models, and the machine learning-based Random Forest model showed the best prediction results. The research results will present an optimal model for accurate demand forecasting in the aviation industry and provide basic information needed for operational planning and resource allocation.

This study analyzed a textbook published for Korean culture education in a trend of communicative teaching methods, and suggested the ways for the integrated diversity of culture education with expression activities. This study set up the final goal of strengthening 'cultural competence' which is the next stage of 'cultural awareness' and 'cultural literacy' in the goal hierarchy for culture education, and analyzed not only the theme distribution but the patterns of expression activities in the textbook. It assumed that one of the most effective ways to achieve the goal is the convergence with expression activities in order to strengthen 'cultural competence' which aims to the creative culture production as well as the simple comparison between learners' mother culture and the target culture. This textbook is characterized by abundant visual materials, focus on the behavior culture and the information culture rather than the achieved culture. and media reading materials in diverse levels for utilization possibly in any proficiency levels. Also, it found out by analyzing the patterns of expression activities that the question forms inducing learners' speech and writing are restricted to a few patterns. Lastly, this study proposed the ways to achieve the goal "cultural competence" as follows: diversity of question forms, extension of expression activities and creative application in integrating the related activities.
