High amounts of lemon seeds are discarded as by-products of processing industries. It is important to find some measures, whereby they could be used in value-added ways. Although few studies have been conducted on lemon seed oils, no study has been conducted on the nutrient content of lemon seed sprouts. The objective of this study was to investigate the nutritional value and antioxidant potential of lemon seeds and sprouts. The 1,1-diphenly-2-picrylhydrazyl radical-scavenging potential, total polyphenol, and total free amino acid content were higher in the sprouts than in the seeds. Similarly, the content of such mineral elements as Fe, Na, and Zn, increased with germination. However, salicylic acid and total mineral content were lower in the sprouts than in the seeds. The results indicate that lemon seeds and sprouts could be regarded as high-value materials in food and cosmetic industries.

The current definition of Arismatis Rhizoma is the tuberous root of Alisma orientale Juzepzuk in the Korean Pharmacopoeia, but there is still no marker compound. So it has difficulties in quality control. Therefore, in this study, we have established a method to analyze alisol B and alisol B acetate using HPLC as a marker compounds of Arismatis Rhizoma. As the result of the analysis, alisol B content was ranged from 0.02% to 0.50% and alisol B acetate content was ranged from 0.12% to 0.25% in 40 samples. The stability of alisol B and alisol B acetate was investigated during 24 months. As a result, alisol B acetate was significantly decreased. The marker compound of Arismatis Rhizoma is alisol B acetate and the content of 0.05% or more is suitable by applying the stability results.

Due to the development of science and technology in the 4th Industrial Revolution, a variety of content is being developed and utilized through educational courses linked to digital textbooks. Students use smart devices to engage in realistic virtual learning experiences, interacting with the content in digital textbooks. However, while many realistic contents offer visual and auditory effects like 3D VR, AR, and holograms, olfactory content that evokes actual sensations has not yet been introduced. Therefore, in this paper, we designed and implemented 4D educational content by adding the sense of smell to existing content. This implemented content was tested in classrooms through a curriculum-based evaluation. Classes taught with olfactory-enhanced content showed a higher percentage of correct answers compared to those using traditional audio-visual materials, indicating improved understanding.

BACKGROUND: Kiwifruit is a fruit tree with relatively small cultivation area in Korea and researches on its soil and physiology are very limited compared to those on cultivar development. Therefore, there are limited information for farmers to cope with the reduction in productivity due to various physiological disorders and premature aging. This study was conducted to investigate the soil and leaf chemical properties, and fruit characteristics, which will be used as basic data for stable kiwifruit orchard soil management. METHODS AND RESULTS: The soil and leaf chemical properties, and fruit characteristics were investigated for two years in 16 kiwifruit orchards growing 'Hayward' (Actinidia deliciosa) in Jeollanam-do and Gyeongsangnam-do. Soil and leaf samples were collected in July and fruit quality was investigated by harvesting fruits about 170 days after full bloom. The average soil chemical properties of kiwi orchards were generally higher than the recommended level, except for pH, and especially, the exchangeable potassium reached about 300% of the recommended level. The proportions of orchards that exceeded the recommended level of soil chemical properties were 63, 31, 100, 69, 94, 88 and 69% for pH, EC, organic content, available phosphate, and exchangeable potassium, calcium and magnesium, respectively. Thirty-three percent of orchards had more than 100 mg/kg of nitrate nitrogen in soil. Available phosphate in soil showed a significantly positive correlation with leaf nitrogen, phosphoric acid and calcium content, but showed a significantly negative correlation with leaf potassium content. The magnesium content in the leaves was significantly correlated with soil pH. The highest fruit weight was observed in about 25 g/kg of leaf nitrogen content which could be attained when plants were grown on the soil containing about 100 mg/kg of nitrate nitrogen content. The average soluble solids content among 16 orchards was 9.58 °Brix at harvest and 13.9 °Brix after ripening, which increased about 45%, and the average fruit weight was about 110 g. CONCLUSION(S): For fruit quality, fruit soluble solids (sugar compounds) content was significantly correlated with leaf potassium content, fruit hardiness with leaf total nitrate, calcium and magnesium, and fruit titratable acidity with leaf magnesium; however, leaf calcium and magnesium negatively affect the soluble solids contents in fruits.
