As men's interest in grooming increases, YouTube videos teaching men about natural makeup that could help them look more presentable are becoming popular. An increasing amount of beauty content on YouTube now targets men. Therefore, this study aimed to identify the features of male-targeted beauty videos with the highest number of views and likes in order to help beauty influencers understand what subscribers want and apply effective marketing strategies. The research method set criteria for YouTuber characteristics, editing elements, and content through prior research, and analyzed through the YouTube website. The video upload date range was set from January 1, 2022 to January 1, 2024. The search keywords "male beauty YouTuber" and "male makeup" were used to find the 10 most viewed videos. The results showed that technical terms, standard words, and loanwords were generally used, and the age group was in their 30s, and the proportion of famous experts was high. The video duration of 10-15 minutes was most common, and the ratio of sound effects, background music, and subtitles was high. Makeup tips and product reviews or recommendations was the most common type of content. Especially, demonstrations of make-up application and product reviews had higher number of views. The findings of this study could provide new ideas and references to YouTubers who aspire to specialize in male beauty content, and help them produce videos that sufficiently satisfy the needs and desires of subscribers.

To screen antagonistic fungi against plant pathogens, dual culture assay (DCA) and culture filtrate assay (CFA) were performed with unknown soil-born fungi. Among the different fungi isolated and screened from the soil, fungal isolate ANU-301 successfully inhibited growth of different plant pathogenic fungi, Colletotrichum acutatum, Alternaria alternata, and Fusarium oxysporum, in DCA and CFA. Morphological characteristics and rDNA internal transcribed spacer sequence analysis identified ANU-301 as Aspergillus terreus. Inoculation of tomato plants with Fusarium oxysporum f. sp. lycopersici (FOL) induced severe wilting symptom; however, co-inoculation with ANU-301 significantly enhanced resistance of tomato plants against FOL. In addition, culture filtrate (CF) of ANU-301 not only showed bacterial growth inhibition activity against Dickeya chrysanthemi (Dc), but also demonstrated protective effect in potato tuber against soft rot disease. Gas chromatography-tandem mass spectrometry analysis of CF of ANU-301 identified 2,4-bis(1-methyl-1-phenylethyl)-phenol (MPP) as the most abundant compound. MPP inhibited growth of Dc, but not of FOL, in a dose-dependent manner, and protected potato tuber from the soft rot disease induced by Dc. In conclusion, Aspergillus terreus ANU-301 could be used and further tested as a potential biological control agent.

Tuber yield and content of general component and diosgenin which is a main bioactive property were investigated in order to determine the growth characteristics of round typed yam(Dioscorea opposita L.) and the potential of artificial culture at Suwon, Korea. Tubers of round yam were initiated to form at 60 days after planting and then enlargement of tubers lasted by 160 days after planting. Compared to short typed yam(108g), tuber weight of round yam was higher(127g) on the basis of dry weight at 200 days after planting. In comparison of general component between round yam and short yam, protein of round yam$(3.62\%)$ was higher than short yam$(2.10\%)$. Water content in round yam$(64.5\%)$ was lower in short yam$(79.4\%)$, indicating a higher dry weight ratio of round yam. Hardness of round yam was 2787.6 while short yam showed about two times higher hardness(4946.9). Lightness was higher in round yam(77.4). In tuber extracts analysis, diosgenin content was respectively $3.32\%$ in round yam and $2.61\%$ in short yam.

Difference in sensitivity of Eleocharis kuroguwai tubers to bensulfuron- methyl{methyl 2-[[[[[(4, 6-dimethoxy-2-pyrimidinyl) amino] carbonyl] amino] sulfonyl] methyl] benzoate} at different burial depths were determined with respect to tuber emergence, sprouting of lateral buds, carbohydrate consumption of the tuber, and growth and new tuber production of the regrown plants. Days required to regrowth from the growth cessation due to bensulfuron-methyl were shorter in shallow-buried tubers than in deep-buried tubers. With application of bensulfuron-methyl shallow-buried tubers consumed less carbohydrate in the tuber than deep-buried tubers as compared with in deep-buried tubers during the period of growth cessation and greater regrowth also occurred in the former. Fast and great regrowth in shallow-buried tubers resulted in great production of dry matter and new tubers. However, the differences obtained were not due to bensulfuron-methyl, but due mainly to ecological emergence and growth characteristics of tubers buried at different depths.

Potate tubers with slver scurf lesions were collected from the cold storage at Pyungchang, Kangwon province in Korea. The causal agent of the silver scurf was identified as Helminthosporium solani by mycological characteristics of conidia and conidiophores. Pathogenicity of the fungus was confirmed by artificial inoculation on the potato tuber. This is the first report of potato silver scarf by Helminthosporium solani in Korea.

This study was carried out to determine distribution and tuberization characteristics of tubers of water chestnut(Eleocharis Kuroguwai Ohwi) which is a dominant weed species and diffult to control during 1993 to 1994. By early planting of E. kuroguwai tubers, more and heavier tubers were developed, but the tubers were tended to distribute at the upper soils. Large proportion of tubers was remained at the upper 0 to 10cm soil layer and a few tubers were formed below 20cm. Tubers developed earlier tended to be at deeper layer, while later developed tubers were at upper layers. Tuber weight was increased from the surface to 20cm soil depths, but that formed below 20cm was almost same. No tillage resulted in more tuber formation which were distributed at upper soil layers when compared to conventional tillage. Cool water irrigation pumped from ground water resulted in less tuberization but smaller tubers when compared to control. Shading with color cellophan films resulted in smaller tuber formation with lower in sprouting percentage. Among the films tested, the most significant effect was obtained with green color.

This study was conducted to evaluate agronomic characteristics such as growth, quality, and yields of StMyb1R-1 transgenic potato and also to obtain the basic data for establishing assessment guidelines of transgenic potato. Three transgenic lines (Myb 1, Myb 2, and Myb 8) were cultivated under conventional irrigation, drought condition, and severe drought condition and were analyzed by comparing with wild type, non-transgenic cv. Superior. Myb 2 showed a different flower color from wild type and Myb 1 had much bigger secondary leaflets than wild type. Myb 1 and Myb 2 showed higher $P_2O_5$ content in both top and root zone and longer shaped tubers than wild type. In yield factors, transgenic lines had more tubers than wild type, however their yield decreases were severe because of the poor enlargement of tuber under water deficit condition. This tendency was noticeable in Myb 1 and Myb 2. In TR ratio, chlorophyll content, dry matter rate, and relative water content, there were no big differences between transgenic lines and wild type. Meanwhile, in phenotype, growth, quality, and yield factors, substantial equivalent was confirmed between Myb 8 and wild type. Then, Myb 8 showed the highest marketable tuber yield under conventional irrigation, while showed lower level than wild type under water deficit. Judged by this result, the enhancing droughttolerance by StMyb1R-1 gene might actually not mean the enhancement of photosynthesis or starch accumulation in tuber and, furthermore, not the yield improvement. More detailed research will be required to accurately understand the relationship between StMyb1R-1 and yield factors.
