The purpose of this study is to empirical case study for the instructional design of flipped classroom by job-capability advancement of IT business majors. A student of IT business school has learned a lot of management educations for four years. But, they don't recognize a connection between school education and business practice. A subject based on the humanities, and social sciences consisted of mostly the memorization. The undergraduate class lack a practice's curriculum by a creative-oriented lesson rather than memorization-oriented. In particular, An IT business is now recognized as a significance emerging IT investment, the Internet of Things, information security, big data and strategy's ERP. For these reasons, it is important for an instructional design for understanding business practices of the students. Accordingly, Flipped classroom with participatory class be needed increasingly for students' practical sense. We will propose a design method of flipped classroom for inspiring business education. In this, new instructional design overturned traditional teaching method. After the student conducts a prior learn at home, school will accomplish a problem solving through question and answer. This design effected a boredom suppress and creative enforcement of student and an intimacy increase of instructor. In addition, A participatory class and reciprocal peer tutoring will be possible by a spontaneous self-directed learning of student. We were designed course of project type based on big data theory and application to target the fourth-year course. In conclusion, the new instruction provided a help to learning synergy between student and lecturer. During the lessons, the student showed improvement of business sense and enhanced problem solving capability. The lecturer has the intimacy through communication interaction with students.

Currently, many universities are implementing software-oriented universities and artificial intelligence-oriented universities to foster software-oriented manpower. We are educating students to design and produce computational thinking and coding directly with their major knowledge. However, computer education is not easy for non-majors, and there are many difficulties in coding. The results of responses from 104 students from the College of Health Sciences and College of Social Management who took the liberal arts computer at University H were analyzed using SPSS 26.0 version. In the liberal arts computer class for non-majors, a PJBL-based class plan was proposed. The effectiveness of PJBL-based classes was confirmed through a questionnaire for the improvement of artificial intelligence liberal arts courses. As a result, PJBL-based education showed statistically significant results in terms of satisfaction, effectiveness, and self-efficiency of classes regardless of major.

An exploratory survey was performed to assess the present status of distribution and production of coconut palm (Cocos nucifera Linn.) in the rural landscape of Meghna floodplain of Bangladesh. A multistage simple random sampling technique was adopted to identify the study area and respondents. A total of 50 households were selected randomly for the study. Traditional knowledge on cultivation, management, and production of coconut palm was emphasized. Marketing of coconut palm products and income derived from coconut palm cultivation was taken into consideration. Perceptions of farmers, traders and professionals were described in due context of opportunities and constraints of coconut palm cultivation. Coconut palm cultivation was found to play an important role in household economy in rural Bangladesh sharing considerable contribution to the total income. About 10% of their total annual income was reported to come from coconut husbandry. Highest number of the coconut palms, 24%, was found to grow in the homestead compounds and in the pond banks. About one-third lands of the households were found to be covered by the coconut palms. Maximum, 19%, coconut palms were found in the 16-20 years age-class. Production of coconut was found highest at the age-class 11-15 years. The study found some important opportunities and constraints of coconut farming in rural Meghna floodplain area of Bangladesh.

This study aimed to develop an ontology for Thai country songs by using the seven steps of an ontology development process. Hozo-Ontology Editor software and Ontology Application Management Framework were tools used in this study. Nine classes of ontology were identified: song, singer, emotion, author, language used, language type, song style, original, and content, and it was found that the song class had a relationship with all of the other classes. The developed ontology was evaluated by seeking opinions from experts in the field of Thai country songs, who agreed that the ontology was highly effective. Additionally, the evaluation employed the knowledge retrieval concept, and the precision, recall, and overall effectiveness were measured, with a precision of 92.59%, a recall of 86.21%, and an overall effectiveness (F-measure) of 89.28%. These results indicate that the developed ontology is highly effective in describing the scope of knowledge of Thai country songs.

The diet composition of john dory Zeus faber, was investigated using 266 specimens collected in the coastal waters of the South Sea, Korea. The specimens ranged in total length (TL) from 12.5 to 43.2 cm. The Z. faber fed mainly on Pisces and less often on Macrura. We further analyzed the data by dividing the specimens into five classes (<15.0 cm, 15.0-20.0 cm, 20.0-25.0 cm, 25.0-30.0 cm, ≥30.0 cm). The Z. faber diet shifted with size class from predominantly consuming Macrura to Pisces. The proportion of Macrura consumed decreased with increasing body size, whereas the consumption of Pisces increased gradually.

In this study, preprocessings with all combinations were examined in terms of the effects on decreasing word number, shortening the duration of the process and the classification success in balanced and imbalanced datasets which were unbalanced in different ratios. The decreases in the word number and the processing time provided by preprocessings were interrelated. It was seen that more successful classifications were made with Turkish datasets and English datasets were affected more from the situation of whether the dataset is balanced or not. It was found out that the incorrect classifications, which are in the classes having few documents in highly imbalanced datasets, were made by assigning to the class close to the related class in terms of topic in Turkish datasets and to the class which have many documents in English datasets. In terms of average scores, the highest classification was obtained in Turkish datasets as follows: with not applying lowercase, applying stemming and removing stop words, and in English datasets as follows: with applying lowercase and stemming, removing stop words. Applying stemming was the most important preprocessing method which increases the success in Turkish datasets, whereas removing stop words in English datasets. The maximum scores revealed that feature selection, feature size and classifier are more effective than preprocessing in classification success. It was concluded that preprocessing is necessary for text classification because it shortens the processing time and can achieve high classification success, a preprocessing method does not have the same effect in all languages, and different preprocessing methods are more successful for different languages.
