  • Fumigaclavine C (FC), an active indole alkaloid, is obtained from endophytic Aspergillus terreus (strain No. FC118) by the root of Rhizophora stylosa (Rhizophoraceae). This study is designed to evaluate whether FC has anti-adipogenic effects in 3T3-L1 adipocytes and whether it ameliorates lipid accumulation in high-fat diet (HFD)-induced obese mice. FC notably increased the levels of glycerol in the culture supernatants and markedly reduced lipid accumulation in 3T3-L1 adipocytes. FC differentially inhibited the expressions of adipogenesis-related genes, including the peroxisome proliferator-activated receptor proteins, CCAAT/enhancer-binding proteins, and sterol regulatory element-binding proteins. FC markedly reduced the expressions of lipid synthesis-related genes, such as the fatty acid binding protein, lipoprotein lipase, and fatty acid synthase. Furthermore, FC significantly increased the expressions of lipolysis-related genes, such as the hormone-sensitive lipase, Aquaporin-7, and adipose triglyceride lipase. In HFD-induced obese mice, intraperitoneal injections of FC decreased both the body weight and visceral adipose tissue weight. FC administration significantly reduced lipid accumulation. Moreover, FC could dose-dependently and differentially regulate the expressions of lipid metabolism-related transcription factors. All these data indicated that FC exhibited anti-obesity effects through modulating adipogenesis and lipolysis.

  • The purpose of this study is to estimate the rate of credit card payment for private education. The results of study can be used to improve credit card handling problems of private educational institutes, leading toward improvements in income transparency, increase in tax burden equity and long-term economic welfare improvement for individual households. 424 households out of 586 household that were surveyed in September of 2002 had 1,700 cases private extracurricular education. 67 of the 1,700 cases that did not have expenditure records were removed from the analysis. Only 3.67% out of 1,633 cases were paid by a credit cards and the amount of credit card payment were only 5.65% of the total amount spent for private education. The average fee of private educational institutes that allow credit card payment was higher than the fees of private institutes which don't allow a credit card payment or those of private institutes where consumers don't know whether a credit card payment was allowed. The average fee of private education paid by credit cards was 34,465.46 won higher than that paid by cash. Credit card payments to private educational institutions is an important social issue with respect to fair tax collection and tax burden equity since most private educational services operate in fairly small sizes and are offered by the self-employed, and the expense of private education is a fairly large proportion of the household income. It is also important for consumers if credit card acceptance expands alternatives that consumers can choose in private education. Therefore, credit card payment should be encouraged in private extracurricular education. To do this, private education providers should be forced to join a credit card payment service by the National Tax Service. A regulation that prohibits the refusal of credit card payments should be required, and credit card service charges of private education providers should be incrementally decreased. Also, consumer education and public promotions for credit card use instead of cash in paying for private education fees are recommended.

  • A one-step fabrication of a photonic crystal (PC) with functional defects is demonstrated. Using multi-beam phase-controlled holographic lithography with a diffracting optical element, large area one dimensional (1D) and two dimensional (2D) PCs with periodic defects were fabricated. The uniform area is up to $2mm^2$, and tens of defect channels have been introduced in the 1D and 2D PC structure. This technique gives rise to substantial reduction in the fabrication complexity and significant improvement in the spatial accuracy of introducing functional defects in photonic crystals. This method can also be used to design and fabricate three dimensional (3D) PCs with periodic defects.

  • Objective: This study aimed to provide policy implications by studying the class size of early childhood education institutes. Methods: By looking through researches, the educational influence of class size was examined. By using the latest statistical data, class size standard and status were compared. After class size perception in the field was considered and the main results of advanced researches were summarized and analyzed, the actual condition of class size was diagnosed. Furthermore, the national research trend was analyzed. Results: First, class size was an influencing factor on young children and teachers and its importance was reconfirmed. Second, as for standard in relation to class size in Korea, the maximum class size and teacher-child ratio were not presented together. In respect of overseas standards, infancy has similar standards, but early childhood has a little higher ratio. In the educational fields, there was growing awareness that class size should be modified. Third, there were not enough domestic researches on class size and they tended to be biased in terms of the method, targets, and contents. Conclusion/Implications: It is suggested that it is necessary to establish a class size policy for future early childhood education institutes, to implement a system, and to perform follow-up studies.

  • The present study compared the contents and methods of elementary science education in schools and education institutes for the gifted and surveyed the contents and methods of science education for the gifted desired by students in order to set the direction of elementary science education at education institutes for the gifted. For this study, we conducted interviews with a 5th-grade male student and a 6th-grade female student at the science class of the Education Institutes for the Gifted run by Iksan Education Office. Besides, printed materials were collected and used to refer to the contents of education. The results of this study are as follows. First, in school, the student learn according to the curriculum defined by the government and the contents begin with elementary and basic ones and move step by step to deeper and wider scientific principles. On the contrary, in the education institute for the gifted, the contents of teaching materials are decided at the teacher's discretion, and because they target gifted children, their level is higher than that of the science curriculum in school. Second, the most common teaching method in school is lecturing and, next, experiments, group activities, etc. On the contrary, in the education institute for the gifted, experiments are used most frequently, and various educational methods are adopted including lectures, project learning and cyber learning. Third, the contents of science education that gifted children wanted to learn are not limited to any specific area. Science education methods that gifted children wanted were various, including project learning, group activities, experiments, and report making and presentation.

  • Nowadays learning has developed to a new way of anywhere and anytime by using mobile devices called m-learning which can provide flexibility, independency and creativity in academic environment. Most studies about m-learning are for higher education and the most users of m-learning are higher education students. Although developed countries are using m-learning in educational sectors, most of the Middle East countries are far from m-learning, and facing number of challenges. In Iran m-learning is still in early stage of implementation in higher education and in terms of technical and infrastructural aspects there is a vast gap in compare with developed countries. Although technical and infrastructural difficulties are one of the significant aspects in implementation and integration of m-learning technologies in education, the technology will not be successful if could not adopt with users. Due to the importance of user adoption with m-learning, there are limited studies about m-learning adoption in higher education of Iran. This paper attempts to review on technical and infrastructural aspects that facilitate m-learning which have effect on adoption of Iran higher education system. The review of the trend in the literature provides a reference for higher education institutes for decision making in developing m-learning for their students.

  • Mobile devices have become attractive learning devices for education. The digitalization of the higher education system in Sri Lanka by 2020 is part of the government's effort to modernize and enhance the country's overall education system particularly in view of the COVID-19 pandemic. Theoretically, this study contributes to the M-Learning model in higher education institutions via the integration of literature on technology adoption (TAM and UTAUT) with the variables of Perceived Usefulness, Perceived Ease of Use, Attitude, Effort Expectancy, Social Influence, and Facilitating Condition. The attitude towards M-Learning amongst higher education students was gauged via an online questionnaire survey. The convenience sample comprised 344 students from the Advanced Technological Institutes (ATI) in Batticaloa District, Sri Lanka. Descriptive statistics, a measurement, and structural model, and hypotheses testing were used to analyze the derived data. The findings indicate that mobile learning is significantly affected by perceived ease of use, social influence, effort expectancy, and facilitating condition, but negatively affected by attitude and perceived usefulness. The exhaustive literature review revealed that there are very few M-Learning studies related to digital learning in the context of higher education in the Batticaloa district.
