This study determined the reality of how middle school students are doing with their free learning semester and what they think about it. Also, the study looked at how many parts of Home Economics and the area of clothing curriculum are being taken and, especially, how many parts of this curriculum content are being required as free learning semester activities. This study aims to not only develop free learning semester activities according to student demand but also at providing a basic resource that can help activate the area of clothing curriculum in subject of Home Economics. In short: 1) Middle school students are attending activities such as career exploration activities, student selection activities, club activities, arts activities and physical education activities thoroughly through the free learning semester. These mostly take place in school and most of the students were taught by teachers from their own school. 2) The students are aware that the free learning semester's activities are helpful for them. The most helpful part was that it reduces the load they get from the school's exam and also the fact that they can investigate areas in which they are interested. 3) The number of students who have already taken or are taking activities related to Home Economics were 145, which is about 1/3 of the 451 students overall. The area where the most of the activities were held out of those activities related to Home Economics was the domain of food while the clothing curriculum accounted for a very small part compared to it. 4) The study found that need for a clothing curriculum for middle school student free learning semesters was about 2.79 on a scale from 1 to 5. The areas of most interest in this topic were highly related to 'making and mending clothes'.

Purpose: This study examined the influence of the consumption values on the attitudes and purchase intentions of consumers towards gluten-free products and compared consumption values, attitudes and purchase intentions according to the degree of health consciousness of the consumer. Methods: The data was collected from July 20, 2016 to August 2, 2016 through a questionnaire survey from three hundred and six consumers who had knowledge of gluten-free products. The data was analyzed by factor analysis, reliability analysis, multiple regression analysis, and an independent sample t-test using the SPSS program. Results: The regression results showed that the exploratory value (p<0.01) had a negative influence on the attitudes, and the functional value (p<0.001) and emotional value (p<0.001) had a positive influence on the consumers' attitudes. In addition, the attitudes (p<0.001) toward gluten-free products had a positive influence on the purchase intentions. Finally, the high health consciousness group answered with a significantly higher score on the consumption values, attitudes and purchase intentions than the lower group. Conclusion: These results highlight the causal relationship among consumption values, attitudes, and purchase intentions of consumers towards gluten-free products, and can provide a basic understanding of gluten free products regarding both marketing strategy and consumers' needs. The potential implications for gluten-free products manufacturers, limitations and future research directions are also discussed.

Fresh mushrooms are vulnerable to browning and tissue changes after harvest. This study monitored the external appearance, physicochemical quality indicators, and nutritional and functional components of a white beech mushroom (Hypsizygus marmoreus) variety (EG2020) newly developed in Korea during cold storage for up to 42 days. Two existing varieties of white H. marmoreus, namely H6 from Korea and HKT from Japan, were used for comparison. The mechanical texture of EG2020 was superior to H6 and HKT due to the increasing hardness of the pileus with time. Browning, in terms of the total color difference during storage, was found to be the most severe in HKT. In terms of composition, EG2020 had the highest total free sugar content, a large amount of organic acids, and higher sugar content than H6 and HKT. EG2020 also contained the largest amount of 𝛽-glucan, and its amount increased during storage. In sensory evaluation, EG2020 received higher scores than HKT in flavor, taste, appearance, and texture. Therefore, the EG2020 variety is more stable than HKT during storage and distribution.

The ${\alpha}-glucosidase$ inhibitory and antioxidant effects of water chestnut (Trapa japonica Flerov.) were assessed to explore its possible use as an anti-diabetic agent. Methanol extracts of the fruit shell and meat of water chestnut were assayed for inhibitory activity against yeast ${\alpha}-glucosidase$ and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Effect of fruit shell extract on postprandial glucose response was assessed. Compared with fruit meat, shell extract showed stronger inhibition against ${\alpha}-glucosidase$ with an $IC_{50}$ of 273 ${\mu}g/mL$. Oral administration of fruit shell extract (500 mg/kg) significantly lowered the postprandial area under the glucose response curve to starch (1 g/kg) in streptozotocin (STZ)-induced diabetic rats (p<0.01). Compared with fruit meat, shell extract showed stronger scavenging activity against DPPH, with an $IC_{50}$ of 27.1 ${\mu}g/mL$. The results indicate that the fruit shell of water chestnut was effective in controlling postprandial hyperglycemia and exerted an antioxidant effect. Therefore, water chestnut may be useful in treating diabetes.

Hawthorn fruit is a conventional medicine used in treating cardiovascular diseases. Its therapeutic effects may relate to its antioxidant compounds. In this study, we evaluated the antioxidant activity of $CH_2Cl_2$, EtOAc, n-butanol and water fractions from 70% methanolic hawthorn fruit extract by total phenolic and flavonoid contents, total antioxidant activity, DPPH free radical scavenging activity, superoxide radical scavenging activity, reducing power assay, lipid peroxidation inhibitory activity and protective effect against hydroxyl-radical-induced DNA damage. Results showed that the EtOAc fraction contained significantly greater antioxidant activities than other fractions, which suggests that the potent EtOAc fraction should be used for further studies to identify the antioxidant compounds.
