  • In this study, we analyzed the dietary style of Chinese singles; in addition, the effect of convenience food consumption on the quality of life of singles was evaluated through construct model development on the relationship between the frequency of consumption and satisfaction with convenience food and quality of life. A statistical analysis of 153 surveys from Tianj was conducted using SPSS 12.0 for Windows and SEM using AMOS 5.0 statistics package. The reliability of the data was confirmed by an exploratory factor analysis and Cronbach's alpha coefficient. The measurement model was confirmed as appropriate by a confirmatory factor analysis of the measurement model in conjunction with AMOS. The results of a factor analysis were as follows. Dietary style was categorized into four factors. The level of satisfaction with convenience food was categorized into seven factors and quality of life was categorized into four factors. The reliability of these findings was supported by a Cronbach's alpha coefficient of 0.6 and higher for all the factors. For the level of satisfaction with convenience food based on dietary style and the quality of life of singles, a structural equation model was constructed and analyzed. The results of all tests indicated that the model satisfied the recommended level of goodness of fit index and thus, the overall research model was appropriate. The current study highlights the increased interest in eating habits of singles and is necessary for further improvement in nutrition education.

  • The purpose of this article is to investigate ways of making the cloze test more valid as an English proficiency test so that it can provide a better format for the cloze test especially to the non-native teachers in EFL environments. This investigation identifies ways of validity in terms of materials, deletion rates, item characteristics and scoring methods used in cloze tests. An increase in test validity can be accomplished by knowing how the four factors affect the cloze test results and how to manipulate them. Practical suggestions are provided for teachers to design a cloze test. Teachers can develop the reliability and validity of cloze tests by manipulating the four factors. In seeking a more valid and reliable cloze format, this research gives some suggestions based on a literature review. We can conclude that a cloze test can be valid only when teachers are aware of the factors which affect the test result and the ways to handle the factors to make the test appropriate for their test purposes.

  • Background and objective: The boom in urban agriculture has also resulted in the creation of many school gardens. With the increase in various hands-on education programs, people are interested in assessing the value of school gardens. This study was conducted to derive indicators for service value assessement of educational farming experience using school gardens. Methods: Through literature review, we selected assessment items and sub-factors. The indicators for evaluating the effectiveness of school gardens are classified using the Delphi method that involve a focus group experts. In order to increase the reliability and validity of the selected and classified items, an exploratory factor analysis was conducted. In addition, the relative importance and priority of each factor in each field were assessed using the analytic hierarchy process (AHP). Results: We classified the indicators into 4 criteria and come up with 13 items and 33 sub-factors in educational value, health value, economic value, and ecological and environmental value. Most of the items for the 4 value criteria derived were significant for assessing the value of agricultural experience services with content validity ratio (CVR) higher than 0.59 and reliability higher than .6 . In the value criteria, the experts rated educational value as the most important, followed by health value, ecological and environmental value, and economic value. In the assessment items, the most important was improvement of social functions. In the sub-factors, the most important was strengthening of ties (friendly interactions). Conclusion: Among the derived indicators assessing the value of school gardens, 4 criteria, 12 evaluation items and 29 sub-factors showed significance. The schematic index would be useful for the assessment.

  • In this paper, we propose a classification method according to the type and characteristics of stablecoins for risk analysis, and analyze the risk factors of each stablecoin based on this classification. First, this paper explains the technologies and ecosystem of blockchain and decentralized finance(DeFi) to understand stablecoins. In addition, the operation principle of the major stablecoins currently released and used is explained for each proposed classification type. Based on this, the risk type and risk factors of each stablecoin are derived. The risk types proposed in this paper are classified as defegging, liquidation, and exploit, and the risk factors are classified as depegging due to reliability of operator, depegging due to reliability of algorithm, depegging due to failure of algorithm, liquidation due to high volatilty and oracle attack. Based on the proposed classification, we analyze the risk factors of major stablecoins currently circulating in the crypto market.

  • The purpose of this study was to investigate the influence of cooking wine's functions on food quality attributes. factor analysis, reliability analysis (Cronbach's $\alpha$), and multiple regression analysis were employed to analyze the data. The cooking wine functions were divided into 3 factors (expectation of utility, functionality, and quality enhancement). According to the multiple regression analysis of cooking wine factors to food quality, all factors had positive influences on food quality. Among the three factors, expectation of utility(=.556, p<0.001) had the most significant influence on food quality. And functionality (=.321, p<0.001) and quality enhancement(=.296, p<=0.001) also had significant effects in that order. further research should be conducted on cooking wine's utility aspects and their effects on food quality. Finally, we anticipate that the results of this study will be useful information for food-service companies.
