Obesity has increased dramatically increased in recent days. It has resulted in obesity-associated diseases and metabolic syndromes including hyperlipidemia, diabetes and cardiovascular diseases. Our study was investigated to determine the antiobese effects of mixed 2 medicinal herbs (AR+AC) in rats fed high-fat diet with an abundance of carbohydrates. Two groups of male Sprague-Dawley rats were fed different diets during 8 weeks: normal diet containing 5% corn oil (w/w), high-fat diet containing 10% (w/w) lard plus 5% (w/w) corn oil (HF). And High-fat diet group was treated with saline or 100 mg/kg ARAC or 300 mg/kg ARAC (PO). Antiobese effect was evaluated by measuring the changes of body weight, adipose tissues weight. Also we examined levels of leptin, adiponectin and lipid profiles in serum. Finally we compared morphological change in adipocytes and hepatocytes between HF and ARAC group. Mixed combination of 2 medicinal herbs, but not alone, caused significant decrease in body weight, organ weight (liver, epididymal fat, and BAT) compared with control HF group. The ARAC group had markedly lower serum levels of adiponectin when compared with HF group. Also the epididymal white adipocyte size of ARAC group were diminished comparing to the HF group. These results suggest that the possibility of ARAC combination, as an antiobese formula, by suppression of body weight gain and increased lipid profiles.

Pumped storage power plant is a system of generating electricity with hydroelectric power, in which at times of low electrical demand such as during nights, excess generation capacity of many power plants is used to pump water into the higher reservoir, and when there is higher demand, water is released back into the lower reservoir through a turbine, generating electricity. As pumped storage power plants across the nation are not on building registry under "the Article 6 of the Special Act by the Development of Power Resources", they are classified as a structure, not as a building. As a result, permit of fire protection facility is unnecessary, and fire protection administration is excluded from approval to completion of construction. Therefore, this study is to improve problems in accordance with the application of "he Article 6 of the Special Act by the Development of Power Resources", repair of facilities and problems with safety control to effectively prevent similar damages from repeatedly happening to pumped storage power plants in operation or under construction nationwide during a fire.

Childhood obesity has more than doubled in children and adolescents in the last decade. Obese youth are more likely to have risk factors for cardiovascular disease and type 2 diabetes such as high cholesterol, high blood pressure, insulin resistance, and metabolic syndrome. There is no single or simple solution to the childhood obesity epidemic, but to learn that obesity is closely related to lifestyle factors including poor fitness and physical inactivity as well as prolonged sitting time in conjunction with westernized dietary habits. In addition to a healthy and balanced diet, promotion of physical activity combined with carefully supervised resistance exercise training, and reduced screen time is a primary recommendation for the prevention and treatment of obesity in children and adolescents. This review provides evidence based data to support this multiple-step physical activity strategy as the most effective and preventive means against childhood obesity.

This study aimed to check habitat distribution and analyze influencing factors by analyzing the mating calls of Auritibicen intermedius inhabiting limited locations in South Korea by applying bioacoustic detection techniques. The study sites were 20 protection areas nationwide. The mating call analysis period was 4 years from 2017 to 2021, excluding 2020. The bioacoustic recording system installed at each study site collected recordings of mating calls every day for 1 minute per hour. Climate data received from the Meteorological Agency, such as temperature, humidity, rainfall, cloudiness, and sunshine, were analyzed. The results of this study identified A. intermedius habitat only in four national parks in the highlands of Gangwon Province (Mt. Seorak, Mt. Odae, Mt. Chiak, and Mt. Taebak) out of 20 study sites. During the four years of study, the mating call period of A. intermedius was between August 5 and September 28, and the duration of the mating call was 31 to 52 days. The temperature analysis during the appearance period of A. intermedius showed that A. intermedius mainly produced mating calls at temperatures between 13.1℃ and 35.3℃, and the average temperature during the circadian cycle of mating calls (09:00 to 16:00) was 24.4 to 24.9℃. The analysis of the circadian cycle of mating calls at four study sites where A. intermedius appeared in 2019 showed that A. intermedius produced mating calls from 06:00 to 16:00 and that they peaked around 11:00 to 12:00. During the appearance period of A. intermedius, four species appeared in common: Hyalessa maculaticollis, Meimuna opalifera, Graptopsaltria nigrofuscata, and Suisha coreana. A logistic regression analysis confirmed that sunlight was the environmental factor affecting the mating call of A. intermedius. Regarding interspecific influence, it was confirmed that A. intermedius exchanged interspecific influence with 4 other common species (H. maculaticollis, M. opalifera, G. nigrofuscata, and S. coreana). The above results confirmed that A. intermedius habitats were limited in the highlands of Gangwon Province highlands in Korea and produced mating calls at a lower temperature compared to other species. These results can be used as basic data for future research on A. intermedius in Korea.

현재 제지용 펄프 및 펼프 원료의 국내 자급상태는 매우 낮은 수준이다. 따라서 원료 가격변동과 환율에 따라 수익성은 물론, 원료 수급에도 큰 영향을 받게 된다. 최근 버 진펄프의 가격상승은 재생펄프 사용량과 고지수입량을 더욱 늘리고 있으며, 이들의 사 용에 따른 품질저하 개선노력도 꾸준히 행해지고 있다. 그러나 원가절감과 품질유지라 는 두 마리 토끼를 한꺼번에 잡는 것은 그리 쉬운 일이 아니며 그 효과 또한 점점 미 미해 지고 있는 실정이다. 외국의 경우 이러한 문제점들을 펄프소재면에서 접근하여 해 결하고자 하는 시도가 있었다. 중국은 벗짚펄프를 제지용으로 적용하여 오랜 시행착오 끝에 성공을 거두고 있으며, 남미에서도 수수 등을 이용한 제지용 펼프 개발에 노력과 투자를 아끼지 않고 있다. 이는 제한된 원료의 사용만으로 직면하고 있는 여러 문제점 들을 해결하기가 힘들다는 언식에서 출발한 것이며, 새로운 원료개발 자체가 그 해결방 안으로서 충분한 가치가 있음을 보여준다고 하겠다. 이와 같은 맥락에 따라 국내에서 적용이 가능한 소재를 조사하였으며 우선적으로 신서란을 선택하게 되었다. 신서란은 뉴질랜드가 원산지로 알려져 있으며 오래전부터 제주도에 자생하고 있는 다년생 초본류이다. 수많은 경질섬유(hard fiber)중에서도 경제적으로 재배되는 유일한 작물로 선박용 로프, 그물, 범포 등의 원료로 사용되었으나 현재는 화학섬유로 대체되 어 그 사용이 전무한 실정이다. 선서란은 고강도와 우수한 유연성, 탄력성 및 양호한 광학적 성질을 가지고 있으며 무엇보다 척박한 땅에서도 생장이 왕성하여 재배가 쉽다 는 것이 가장 큰 장점이다. 본 연구는 펄프용 섬유로서 양호한 기본특성을 가진 신서란 을 이용한 펄프를 기존 제지공정에 일정량 투입함으로써 얻고자 하는 종이의 일반물성 개선 및 특수기능 향상에 도움이 되는 제지용 펄프로서의 가능성을 알아보고자 하였다.이어서 몇십%의 현을 억제하지는 못한다는 결론을 도출할 수 있었다. 연구의 결과를 요약하면 다음과 같다. 첫째, 한국과 미국 패션제품의 지난 십년간의 가격 과 품질의 상관관계는 매우 약한 정(+)의 상관을 가지고 있었다. 한국패션제품의 전체 서열상관계수의 평균은 0.091이었고, 미국의 상관계수 평균은 0.192였 다. 상관계수의 수치만으로 볼 때 한국보다는 미국 패션제품의 가격과 품질간의 상관관계가 조금 높게 나타났으나, 양국간 통계적인 차이는 없었다. 또한, 한국 패션제품의 경우에는 제품군의 가격대별 상관관계를 살펴보았는데, 그 결과 1만원 미만의 저가 제품군과 330만원이상의 고가의 제품군의 경우 부(-)의 상관계수를 나타냈다. 둘째. 1990년대 한국과 미국 패션시장의 가격과 품질간의 상관계수의 범위는 제품군별. 산업범주별 로 상이한 분포를 보이고 있었다. 패션제품군별로 보 면, 한국의 경우는 가장 높은 '여행용가방(r = 0.707)' 에서 가장 낮은 '자외선 차단화장품(r = -0.58)'까지, 그리고 미국 패션제품군의 상관계수의 범위는 '팬티 스타킹'의 0.820에서 '남성용 런닝슈즈'의 -0.472까지의 분포를 나타냈다. 마지막으로, 제품의 가격과 품질에 대한 정보를 소비자가 알 경우 얻을 수 있는 소비자의 구매이득 을 추산한 결과 패션제품시장에서 완전한 품질정보를 가지고 있다고 가정한 '현명한 사람'은, 최고가격의 제품만을 구입한다고 가정한 '부유한 사람들'의 구입방식에 비해 최고 좋은 품질의 상품을 총 지불액의 비율로 보아, 한국의 소비자는 약 50% 정도를, 미국의 소비자는 약 91%나 되는 액수를 절약하여 구매할 수 있는 것으로 나타났다. 이상의 본 연구의 결과를 종합하여 볼 때 한국과 미국 모두 제품군별, 그리고 산업범주별로 상관관계가 차이를 보이고 있어, 양국의 소비자들이 패션제품 의 품질을 평가함에 있어 오로지 가격에 대한

Purpose: This study examined the effects of duck meats with turmeric powder on blood lipids in 10 female university students. Methods: The subjects received duck meat with 0%, 0.1%, 0.2%, and 0.4% turmeric powder and glucose, total cholesterol, triglyceride (TG), high-density lipoprotein (HDL)-cholesterol, and low-density lipoprotein (LDL)-cholesterol in their serums after 30, 60, 90, 120, and 180 min were measured. Results: The average height, weight, and body mass index of subjects were $159.6{\pm}2.6cm$, $51.3{\pm}3.5kg$, and $20.1{\pm}1.0$, respectively. The fasting glucose, ${\gamma}-glutamyl$ transferase (GGT), glutamic pyruvic transferase (GPT), glutamic oxaloacetic transferase (GOT), c-reactive protein (CRP), and hemoglobin were within the normal range. The ${\Delta}-AUC$ (area under the curve) of postprandial glucose, TG did not change, but ${\Delta}-AUC$ of postprandial total cholesterol and LDL were significantly decreased, and HDL was increased by intake of the duck meat with turmeric powder. Conclusion: This study shows that duck meats with turmeric powder affected the postprandial blood lipid levels.

In this study, sorghum teas were prepared from Sorghum bicolor L. Moench subjected to different types of milling (no milling (0%), minimum milling (5%), and milling (20%)) and pan-firing times (1 to 10 minutes), and its quality characteristics were investigated. With regards to milling type, total polyphenolic, flavonoid, tannin contents, and antioxidant activities of ethanol extracts from both no milling sorghum and its tea were highest, followed by minimum milling and milling in decreasing order. Crude nitrogen content was highest in milling sorghum and its tea regardless of pan-firing time. With regards to pan-firing time, total polyphenolic, flavonoid, tannin contents, and antioxidant activities of sorghum teas increased with increasing pan-firing time regardless of milling type. The highest DPPH and ABTS radical scavenging activities were observed at a pan-firing time between 7 to 9 minutes. In contrast to ethanol extracts of pan-fried sorghum tea, antioxidant activities, chromaticity, and turbidity of hot water leaching liqueur of sorghum tea were highest in milling sorghum tea, followed by minimum milling and no milling sorghum tea.

To identify nutritional and therapeutic properties of the new Korean red waxy sorghum cultivar ‘Hwanggeumchalsusu (HGC)’, we assayed the antioxidative effects and neuraminidase inhibitory activity. A methanol and 70% ethanol extract of HGC exhibited strong antioxidative effects (IC₅₀ values of 83.2±2.7 for DPPH) and 85.6±2.4 μg/ml for ABTS) and neuraminidase (ND) inhibitory activity (IC₅₀ values of 1.8±0.1 from extracted with methanol and 3.4±0.1 μg/ml from extracted with 70% ethanol) compared with that of the control, noncolored sorghum cultivar ‘Huinchalsusu (HC)’ (IC₅₀> 200 μg/ml). We isolated nine polyphenols, Gallic acid (1), Protocatecuic acid (2), p-Hydroxy benzoic acid (3), Vanillic acid (4), Caffeic acid (5), Ferulic acid (6), Luteolinidin (7), Apigeninidin (8), Luteolin (9), from the HGC - methanol extract, to determine whether they were the active components Luteolinidin of one kind of polyphenols from the HGC, exhibited significant antioxidative effects (IC₅₀ values of 10.9±0.5 μM for DPPH and 8.6 0.6 μM for ABTS) and neuraminidase (ND) inhibitory activity (IC₅₀ values of 26.3±0.6) showed noncompetitive inhibition model. The binding affinity of the ND inhibitors in molecular docking experiments correlated with their ND inhibitory activities. These results suggest that HGC may be utilized to serve as a potential effective antioxidant and inhibitor of ND.
