Apparent digestibility coefficients (ADCs) of dry matter, crude protein, crude lipid, nitrogen-free extract, energy and essential amino acids in animal-based feed ingredients were determined for olive flounder (Paralichthys olivaceus). A reference diet (RF) was formulated to contain 1.0% chromic oxide (Cr₂O₃) as an inert indicator. Nine test diets were formulated to contain RF and one of the feed ingredients (pollock meal [PM], jack mackerel meal [JMM], anchovy meal [AM], cod meal [CM], sardine meal [SM], sand eel meal [SEM], tuna meal [TM], meat meal [MM] and squid liver meal [SLM]) at a 7:3 ratio in each diet designated as PM, JMM, AM, CM, SM, SEM, TM, MM and SLM, respectively. Olive flounder, averaging 150 ± 8.0 g, were stocked at a density of 25 fish per tank in 400-L fiberglass tanks attached with fecal collection columns. Feces were collected from triplicate groups of fish one time a day for four weeks. Dry matter and crude protein ADCs of CM and SEM were significantly higher than the other tested ingredients. Lipid ADCs of JMM, CM and SEM were significantly higher than the other test ingredients. Energy ADCs of CM and SEM were significantly higher than that of the other tested ingredients. The availability of amino acids in CM was generally higher than the other animal protein sources. PM exhibited the lowest amino acid availability among the treatments. Interestingly, MM exhibited significantly higher nutrient digestibility than several marine-based ingredients. However, CM and SEM are seeming to be highly digestible and effective to use in olive flounder diet compared to the other tested ingredients. Overall, the results of this study provide information about the bioavailability of nutrients and energy in animal feedstuffs to apply when formulating cost-effective practical feeds for olive flounder.

Kimchi showed protective effect from oxidative damage generated by hydrogen peroxide and paraquat. To investigate the major components of kimchi which reduce the cytotoxicity against reactive oxygen species, keratinocyte(A431, epidermoid carcinoma, human) and fibroblast(CCD-986SK, normal control, human) were cultured under oxidative stress condition provoked by paraquat, a superoxide anion generator, and hydrogen peroxide in the absence or presence of kimchi ingredients. Most keratinocyte and fibroblast cells were killed by hydrogen peroxide and paraquat over 1mM concentration, but kimchi ingredients showed protective effects from oxidative damage generated by hydrogen peroxide and onion, among those, garlic showed the most remarkable preventive effect. Most of kimchi ingredients showed protective effect against paraquat, especially leek notably increased cell survival. For fibroblast cells, ginger had the preventive effect against paraquat, especially leek notably increased cell survival. For fibroblast cells, ginger had the preventive effect from cell killing by high dose of hydrogen peroxide, but most ingredients were not effective against paraquat.

There are people who are sensitive to cosmetic ingredients, such as pregnant women and skin disease patients. There are also people who experience side effects from cosmetics. To avoid this, it is cumbersome to search for harmful ingredients in cosmetics one by one when shopping. In addition, knowing and remembering functional ingredients that suit you is helpful when purchasing new cosmetics. There is a need for a system that allows you to immediately know the cosmetics ingredients in the field through photography. In this paper, we introduce an application for smartphones, <Hwa Ahn>, which allows you to immediately know the cosmetics ingredients by photographing the ingredients displayed in the cosmetics. This system is more effective and convenient than the existing system in that it automatically recognizes and automatically classifies the ingredients of the cosmetic when the camera is illuminated on the cosmetic ingredients or retrieves the photos of the cosmetic ingredients from the album. If the system is widely used, it is expected that it will prevent skin diseases caused by cosmetics in daily life and reduce purchases of cosmetics that are not suitable for you.

BACKGROUND/OBJECTIVES: We investigated total 26 ingredients of Saengshik which will be commercially produced as an anti-diabetic dietary supplement. SUBJECTS/METHODS: Thirteen vegetables, nine cereals, three legumes and one seed were extracted with aqueous ethanol for 2 h at $60^{\circ}C$, and evaluated for their inhibitory effects against ${\alpha}$-amylase and ${\alpha}$-glucosidase and for total phenolic and flavonoid contents. RESULTS: All ingredients inhibited ${\alpha}$-amylase activity except cabbage. Strong inhibitory activity of ${\alpha}$-amylase was observed in leek, black rice, angelica and barley compared with acarbose as a positive control. Stronger inhibition of ${\alpha}$-glucosidase activity was found in small water dropwort, radish leaves, sorghum and cabbage than acarbose. All Saengshik ingredients suppressed ${\alpha}$-glucosidase activity in the range of 0.3-60.5%. Most ingredients contained total phenols which were in the range of 1.2-229.4 mg gallic acid equivalent/g dried extract. But, total phenolic contents were not observed in carrot, pumpkin and radish. All ingredients contained flavonoid in the range of 11.6-380.7 mg catechin equivalent/g dried extract. CONCLUSIONS: Our results demonstrate that Saengshik containing these ingredients would be an effective dietary supplement for diabetes.

As there is a growing interest in natural ingredients, they are actively being studied to improve damaged skin However, the lip cosmetics are still being inadequately studied on the exposure of lips to several stimuli and easy flow of chemical on the lips into the body. This study was conducted to make a clinical evaluation on the real effect of lip balm on lips, by extracting oil from Chamaecyparis obtusa and Lithospermum erythrorhizon that are known to play a positive role on skin. The following three natural lip balms were produced: lip balm made with Chamaecyparis obtusa(LBWCO), lip balm made with both Chamaecyparis obtusa and Lithospermum erythrorhizon(LBWCOLE), lip balm made without Chamaecyparis obtusa or Lithospermum erythrorhizon(LBWICOLE). The quality of LBWCO or LBWCOLE was evaluated to be higher than that of LBWICOLE. LBWCO and LBWCOLE had the highest satisfaction and purchase intention, respectively. As stated above, Chamaecyparis obtusa and Lithospermum erythrorhizon could be the ingredients of lip balm, and they were effective in improving damaged lips. Consequently, this study will provide opportunities to explore excellent ingredients to be used in natural lip balm. Also, studying lip cosmetics using only the natural ingredients will provide opportunities to expand positive images of ingredients for producing lip cosmetics.

The purpose of this study is, as a prior stage to produce manufactured medical goods, to examine literature on the medicinal efficacy of natural dyes that can be used to produce medical goods, and to experiment the possibility of dyeing of some medicinal ingredients that have not been used as natural dyes until now. For this study, 44 types of medicinal ingredients such as Gyomaekchil(buckwheat), Nohoiyeob(aloe), Pogongyounng(dandelion), and Jibooja(broom cypress) were used. First, they were classified by a thermal sensation such as hot, warm, neutral, cool, and cold feeling, and by their characteristics of complex tastes such as sweet, sour, bitter, salty, pungent, astringent, and flat tastes. And then they were dyed with two types of mordant, resulting to a total of 132 types of dyed cloths. The 132 dyed cloths could be classified as five types of colors: 89 types(67.42%) of yellow series, 25 types(18.94%) of yellow-red series, 6 types(4.55%) of green-yellow series, 6 types(4.55%) of purple series, and 6 types(4.55%) of purple-blue series. The results of this study found that there were various medicinal ingredients that had efficacy to cure skin disorders and also could be used as natural dyes.

In 2022, the domestic production performance of functional cosmetics in South Korea reached 4.6 trillion won, accounting for 33.85% of the total cosmetics production. The number of functional cosmetics reviewed increased by about 7.5% from the previous year, totaling 974 items. Especially with the increasing importance of the skin barrier function due to skin sensitivity caused by various environmental pollutants, domestic cosmetic companies are showing interest in the development of new ingredients and products related to this area. This study aims to analyze academic research trends related to in vitro experiments for the development of cosmetics improving the skin barrier, to provide practical information for the cosmetic industry. The findings are as follows: Academic research mainly focused on the efficacy of natural ingredients in improving the skin barrier, but there is a significant lack of quantitative accumulation of research. For the development of skin barrier-improving cosmetic ingredients, efficacy evaluation indicators were set, including hyaluronic acid production, expression of filaggrin gene, loricrin, formation of cornified envelope (CE), and expression of ceramide synthesis enzyme genes. Moreover, effective cosmetic ingredients for improving the skin barrier included lemongrass and perilla leaf extracts, flavonoids, Lactococcus lactis subsp. lactis, Exosomelike Nanovesicles derived from apple callus, Eleutherococcus sessiliflorus, Acanthopanax sessiliflorus, Eleutherococcus gracilistylus, Acer okamotoanum extracts, Aloe vera adventitious root extract, ethanol extract of Aruncus dioicus, and organic solvent fraction of Dracocephalum argunense.

The heat-mediated reflux apparatus extraction of Paeonia lactiflora Pall. has been widely used as a traditional extraction method. In this paper, the microwave apparatus extraction method of Paeonia Radix was performed and the active ingredients and functional constituents were compared with the reference extraction method. The most effective extraction condition of albiflorin using the microwave was 120℃ in 50% methanol, and paeoniflorin was maximally extracted at 60℃. The reduced level of paeoniflorin molecule at high-pressure and high-temperature extraction condition was caused by the molecular instability. Additionally, the microwave extraction of 50% methanol extracts at 150℃ showed the highest functional constituents determined by in vitro DPPH radical scavenging activity, polyphenol concentration, and tyrosinase inhibition assay. The microwave apparatus was adapted as a rapid, low-cost, and environmentally friendly method to extract active ingredients and the practical extraction conditions of Paeonia Radix can be used in industrial applications.
