Tight control of blood glucose is the most important strategy for the treatment of diabetes mellitus. Here, we investigated the beneficial effects of Welsh onion on fasting and postprandial hyperglycemia. Inhibitory activities of hot water extracts from the green stalk and white bulb, which are the edible portions of the Welsh onion, and the fibrous root extract against yeast ${\alpha}$-glucosidase were measured in vitro. To study the effects of Welsh onion on postprandial hyperglycemia, a starch solution (1 g/kg) with and without Welsh onion fibrous root extract (500 mg/kg) or acarbose (50 mg/kg) was administered to streptozotocin-induced diabetic rats after an overnight fast. Postprandial plasma glucose levels were measured and incremental areas under the response curve were calculated. To study the hypoglycemic effects of chronic feeding of Welsh onion, five-week-old db/db mice were fed an AIN-93G diet or a diet containing either Welsh onion fibrous root extract at 0.5% or acarbose at 0.05% for 7 weeks after 1 week of adaptation. Fasting plasma glucose and blood glycated hemoglobin were measured. Compared to the extract from the edible portions of Welsh onion, the fibrous root extract showed stronger inhibition against yeast ${\alpha}$-glucosidase, with an $IC_{50}$ of 239 ${\mu}g/mL$. Oral administration of Welsh onion fibrous root extract (500 mg/kg) and acarbose (50 mg/kg) significantly decreased incremental plasma glucose levels 30-120 min after oral ingestion of starch as well as the area under the postprandial glucose response curve, compared to the control group (P < 0.01). The plasma glucose and blood glycated hemoglobin levels of the Welsh onion group were significantly lower than those of the control group (P < 0.01), and were not significantly different from those fed acarbose. Thus, we conclude that the fibrous root of Welsh onion is effective in controlling hyperglycemia in animal models of diabetes mellitus.

The purpose of this study is to develop learning materials for functional concept on variable and to verify the effect of how well students could learn functional concept after they studied with those materials. To accomplish the purpose of this study, I developed learning materials and after teaching students with them. I have concluded the followings : First, there was little effect in teaching functional concept on variable between two experimental groups, whereas teaching functional concept had greater effect on forming functional concept in high level groups in those two experimental groups. Second, teaching functional concept on variable had little effect on students' understanding of functional concept and perfecting tables in Black box, graph, and mathematical problems, whereas there was much effect in students' understanding functional concept and solving relation formula, image, and range problems related to everyday life or general things. On the basis of the problems which appeared in the process of this study, the following can be suggested : First, we should develop learning materials fit for low level students so that they could understand functional concept. Second, we should continue to teach the basic problems like solving relation formula, image, and range, and understanding functional concept in graph until students are able to understand them exactly. Third, since the goals of Unit Function in a middle school textbook is to solve problems related to everyday life through functional thinking, there should be change in constructing systematic contents of Unit Function in a middle school textbook.

This study examined the background of the dietary life of North Korean defector adolescents born and raised in North Korea and their new South Korean dietary experiences after being settled in South Korea. The study included six North Korean defector adolescents enrolled in an alternative school located in Gyeonggi-do, South Korea. This study's qualitative research methodology included two-by-two group interviews, followed by individual interviews and field observation. The study period was from September 14 to October 26, 2019. Before entering South Korea, they primarily ate food pickled with soybean and salt, a cooking method by which foods are preserved because refrigerators were unavailable. After settling in South Korea, they had difficulty adapting to South Korean foods because of the unfamiliar ingredients and recipes. On the other hand, they quickly adapted to some foods, such as chicken. The participants reported that North Korean foods are generally light, whereas South Korean foods are sweet, salty, and spicy; hence, they do not taste delicious. The results suggest that attention be paid to menu improvement and the provision of nutritional education by schools and the government to prevent undernourishment or malnourishment because of unfamiliar ingredients and recipes.

To determine the effects of short-term dietary supplementation of branched-chain amino acids (BCAAs) during nursing (from 3 to 28 days of age) on plasma BCAA levels and subsequent growths in cattle, 12 nursing male Holstein calves, randomly assigned to control and treatment groups (n = 6 in each group), orally received a daily supplement of essential BCAAs (2 g/kg body weight/day; 1:1:1 of valine, leucine and isoleucine) or not. The plasma BCAA levels increased linearly after the administration. During the treatment period, average daily gain (ADG) was lower in the treatment group (0.43${\pm}$0.07 kg/day) than the controls (0.71${\pm}$0.07 kg/day, p<0.05). However, at 2 months of age, ADG was significantly higher in the BCAA-treated group (1.16${\pm}$0.26 kg/day vs. 0.51${\pm}$0.06 kg/day, p<0.05). Furthermore, at age 8, 9 and 10 month, ADG in the treated group (1.35${\pm}$0.23, 1.46${\pm}$0.07 and 1.60${\pm}$0.16 kg/day, respectively) showed a linear increase and was significantly higher than that in the control group (0.88${\pm}$0.14, 0.70${\pm}$0.21 and 1.11${\pm}$0.11 kg/kg, respectively, p<0.05). Overall, ADG was 15.6% higher in the treatment group (1.26${\pm}$0.05 kg vs. 1.09${\pm}$0.04 kg; p<0.05). The final body weight at slaughter was 14.8% higher in the treatment group (759.5${\pm}$17.7 kg vs. 661.7${\pm}$21.2 kg, p<0.01). Thus, the supplementation of BCAAs during nursing improves ADG and carcass weight in cattle and is a useful husbandry technique for beef cattle.

This is a quasi-experimental study with one-group pretest-posttest design to investigate the effect of dementia club activities on college life satisfaction, dementia knowledge, and dementia attitude in nursing students. The subjects were 26 nursing students who participated in club activities for more than three hours per a week. The college life satisfaction was measured using School Life Satisfaction Scale and dementia knowledge was measuring using Questionnaire for Awareness of Dementia used in dementia prevalence survey. Dementia Attitude Scale (DAS) was used to measure dementia attitude. The tests were performed before and after club activity, and collected data were analyzed using descriptive statistics and paired sample t-test. The results showed that the scores of college life satisfaction (t=-2.38, p= .025), dementia knowledge (t=-5.56, p< .001), dementia attitude social comfort that evaluate emotion, behavior, and awareness about dementia (t=-4.50, p< .001), dementia attitude dementia knowledge (t=-2.59, p= .016), and dementia attitude total score (t=-4.20, p< .001) increased statistically significantly after club activity. It is concluded, based on the results, that the club activities in college improve college life satisfaction, dementia knowledge, and dementia attitude thus provide contribute to caring for patients with dementia. The replication studies with larger random samples, however, are necessary to confirm the findings obtained from this study.

Purpose: This study was performed to identify the prevalence and type of urinary incontinence (UI) after a stroke, to find the differences in urinary symptoms according to continence or incontinence, and to find the degree of impact of UI on daily life. Method: For data collection, we had a structured interview with a questionnaire. The subjects were 239 post stroke patients. Results: Among the subjects(mean age: $65{\pm}10$), 66.1 percent had an infarction, and 25.5 percent had a hemorrhage. And 26.4 percent of subjects were within 2 weeks and 28.9 percent from 1 year to 5 years since their episodes of a stroke. Forty five point six percent of subjects had various types of UI: urge 25.7 percent, stress 14.7 percent, functional 20.2 percent, and mixed 39.4 percent. There were significant differences in frequency, nocturia, decreased stream, and incomplete emptying between the incontinent and continent groups. Subjects reported UI influenced various aspect of daily life, 54.1 percent as cause of distress, 53.2 percent on overall quality of life, and 40.4 percent on sleep. The Mixed UI, including urge UI, had higher impact on daily life than others. Conclusion: There was a high prevalence of UI, mixed, urge, and functional type as most prevalent, and it had a strong impact on daily life of post stroke patients.

In this study, keywords from representative online portal sites such as Naver, Google, and Youtube were collected based on text mining analysis technique using Textom to check the changes in metqaverse after COVID-19. before Corona, it was confirmed that social media platforms such as Kakao Talk, Facebook, and Twitter were mentioned, and among the four metaverse, consumer awareness was still concentrated in the field of life logging. However, after Corona, keywords from Roblox, Fortnite, and Geppetto appeared, and keywords such as Universe, Space, Meta, and the world appeared, so Metaverse was recognized as a virtual world. As a result, it was confirmed that consumer perception changed from the life logging of Metaverse to the mirror world. Third, keywords such as cryptocurrency, cryptocurrency, coin, and exchange appeared before Corona, and the word frequency ranking for blockchain, which is an underlying technology, was high, but after Corona, the word frequency ranking fell significantly as mentioned above.

Objective: Yunnan is not only a frontier zone that connects China with South and Southeast Asia, but also represents an admixture zone between taurine (Bos taurus) and zebu (Bos indicus) cattle. The purpose of this study is to understand the level of genomic diversity and the extent of admixture in each Yunnan native cattle breed. Methods: All 120 individuals were genotyped using Illumina BovineHD BeadChip (777,962 single nucleotide polymorphisms [SNPs]). Quality control and genomic diversity indexes were calculated using PLINK software. The principal component analysis (PCA) was assessed using SMARTPCA program implemented in EIGENSOFT software. The ADMIXTURE software was used to reveal admixture patterns among breeds. Results: A total of 604,630 SNPs was obtained after quality control procedures. Among six breeds, the highest level of mean heterozygosity was found in Zhaotong cattle from Northeastern Yunnan, whereas the lowest level of heterozygosity was detected in Dehong humped cattle from Western Yunnan. The PCA based on a pruned dataset of 233,788 SNPs clearly separated Dehong humped cattle (supposed to be a pure zebu breed) from other five breeds. The admixture analysis further revealed two clusters (K = 2 with the lowest cross validation error), corresponding to taurine and zebu cattle lineages. All six breeds except for Dehong humped cattle showed different degrees of admixture between taurine and zebu cattle. As expected, Dehong humped cattle showed no signature of taurine cattle influence. Conclusion: Overall, considerable genomic diversity was found in six Yunnan native cattle breeds except for Dehong humped cattle from Western Yunnan. Dehong humped cattle is a pure zebu breed, while other five breeds had admixed origins with different extents of admixture between taurine and zebu cattle. Such admixture by crossbreeding between zebu and taurine cattle facilitated the spread of zebu cattle from tropical and subtropical regions to other highland regions in Yunnan.
