In addition, the expression level of p53 was decreased by E. Sinica. Conclusion : It is suggest that E. Sinica stimulates the thermogenesis of brown adipocytes via p53 inhibition.

본 연구는 지방산 함량 및 배합사료와 조사료 비율을 기초로 한 유기농 사료 급여가 홀 스타인 착유우에서 생산된 원유의 CLA 및 지방산 함량에 미치는 연구를 조사하기 위한 목 적으로 실시하였다. 총 290두의 홀스타인 착유우를 산차 및 유량에 따라 3개 group으로 나 누었다. 대조구는 C16:00, C18:2 그리고 SFA를 높게 설계하였고, 처리구 1은 C18:1, C18:2 그리고 UFA 함량을 높게 설계하였으며 처리구 2는 MUFA, C18:3 그리고 PUFA 함량을 높 게 설계하였다. 결과를 요약하면 다음과 같다. 유기농 원유 내 C16:0 함량은 처리구 2에서 가장 높은 것으로 나타났다(p<0.05). 그 이유는 반추위 내 미생물의 de novo 생합성 때문인 것으로 판단된다. 처리구 2의 C18:0 함량은 7.92%로 대조구(11.39%)와 처리구 1(10.88%)보 다 높았다(p<0.05). CLA 함량도 처리구 2가 처리구 1이나 대조구에 비하여 높은 것으로 나 타났다(p<0.05). 원유 내에서 검출된 대부분의 CLA는 착유우 유선조직내의 △9-desaturase에 의하여 합성된 것으로 판단된다. n-3/n-6 비율도 처리구 2에서 가장 높은 것으로 나타났다 (p<0.05). 본 연구 결과를 종합해 보면, 착유우에게 혼합 목건초 등을 급여하면 CLA, n-3 농 도는 증가하며 C18:0 농도는 낮아지는 것으로 조사되었다. 본 연구는 유기농 인증된 조사 료 및 농후사료를 이용하여 결과를 도출하였다. 그러나 유기농 사료를 사용할 경우에만 원 유 내 CLA 및 n-3 농도는 증가한다고 볼 수 없다. 원유 내 고농도의 CLA 및 n-3 지방산 생 산을 위해서는 반추위 미생물 및 유선세포의 지방 대사를 통한 CLA 생산 메커니즘에 대한 충분한 이해와 급여 사료 내 지방산 구성 등이 중요한 것으로 판단된다.

This study was investigated to develop mass evaluation system for the contents of crude protein, oil and fatty acid in soybean germplasm using NIRS. NIRS equations were created with 345 soybeans, multiple correlation coefficients of crude protein, oil, palmitic, stearic, oleic, linoleic and linolenic acid between data obtained from NIRS and quantitative analysis were 0.983, 0.969, 0.592, 0.514, 0.978, 0.961 and 0.957, respectively. Equation statistics indicated that contents of crude protein, oil and unsaturated fatty acid except palmitic and stearic acid in soybean seed were suitable for determination by NIRS. Those NIRS equations were applied to examine crude protein, oil and unsaturated fatty acid of 854 soybean landraces from Korea. The average contents and ranges of crude protein and oil were 39.2% with a range of 33.7-47.0% and 15.0% with a range of 9.8-20.3%, individually. In addition, those of oleic, linoleic and linolenic acid were 21.4% with a range of 12.1-30.2%, 55.6% with a 47.8-62.3% and 8.1% with a range of 5.9-10.7% respectively. We conducted quantitative analysis to reconfirm with IT154552 (45.1%) and IT023955(46.9%) above 45% of crude protein, the results were similar from NIRS (45.2%, 47.0%). NIRS data for protein from this study made no difference with lab data, which would be useful for mass evaluation. There was negative correlation (-0.203) between crude protein and oil, positive correlation (0.379) between crude oil and oleic acid, and significantly negative correlation (-0.879) between oleic and linoleic acid.

This study is to make a comparison between the one liquid emulsion with and without fish oil containing higher omega-3 fatty acid in parenteral nutrition (PN) of newborns. Serum chemistry and clinical complications from Medical Records of 76 newborns who had received PN with either SMOFlipidⓇ or ClinOleicⓇ for at least 7 days in NICU at Chosun Univeristy Hospital from January 2011 to December 2014 were reviewed retrospectively. Serum chemistry revealed no significant difference between the two groups except for total bilirubin (TB), glucose, blood urea nitrate (BUN), creatine (Cr), and cholesterol, but they even were not clinically significant as their values were within almost normal range. In terms of the difference in clinical complications, the incidence of cholestasis was higher in newborns given ClinOleicⓇ. However, there was no statistically significance. In this study, no significant difference between ClinOleicⓇ and SMOFlipidⓇ in their clinical efficacy was proven. But, considering the advantage of omega-3 fatty acid in reduction of cholestasis and infection risk, more studies may be needed using lipid emulsions containing higher content of fish oil with high omega-3 fatty acid, and they may be better if done with larger groups.

Biochemical methane potential (BMP) of residual wastes from transesterification was tested to safely recycle carcass via rendering process. The carcass was obtained from a buried site for avian influenza (AI) infected poultry. Rendered lipid generated by a pilot-scale high-pressure rendering process was the main source of transesterification for biodiesel recovery. To test the feasibility of waste-to-energy approach for AI infected carcass, we compared the BMPs of various fractions of rendered materials from the carcass. BMP and specific methanogenic activity results indicate that transesterification waste shows better digestibility than that of rendered lipid, and the digestion performance was comparable to that of liquid residue. Biogas yields of glycerol, rendered lipids, and liquid residue were estimated as 0.11 L/g chemical oxygen demand (COD), 0.06 L/g COD, and 0.17 L/g COD, respectively. Regression analysis support that biogas production rate of glycerol (21 mL/g COD/d) was much faster than that of lipid (7 mL/g COD/d) while that of liquid residue was similar (24 mL/g COD/d). In summary using transesterification waste as a bioresource for bioenergy conversion can be a viable and sustainable option for the complete termination of burial site.

This research was intended to provide a method to improve competitiveness, based on the integration of basic municipalities by assessing changes in their population and local industry Municipalities were integrated based on the addressing system 市(Shi), 町(Chome), 村(Village) of Japan. As a result, an actual increase of the population could not be seen in the new municipalities formed by the integration of the basic municipalities. It is also found that the shipping volumes, number of companies, and the number of people employed by local industry, attracted by such municipalities, has steadily decreased. However, even though the proportion of industrysharing in the local municipalities is not significant, it was found that the number of tourists has increased. Therefore, it is concluded that the strengthening of the connectivity between local industry and the tourism industry can be one of the principal methods to strengthen the competitiveness of these municipalities. In addition, it has been found that scientific research from a variety of perspectives and verification of data related to the effectiveness of integration of local municipalities is necessary.

좌심실 이완기능 장애는 심근허혈이나 좌심실비대 등과 같은 심근질환이 잇는 환자에서 대부분 관찰되지만 심장질환이 없는 건강한 사람에서도 흔하게 관찰된다. 정상 심박출(수축기능)상태에서 좌심실의 이완기 장애 평가는 심부전의 진행과 예후에 영향을 줄 수 있다. 심장외막지방조직은 생리활성분자를 생성하는 대사활동기관으로 심혈관질환에 직접적으로 연관성이 있으며 이는 심근에 직접적으로 영향을 미쳐 이후 심장의 기능장애를 초래한다. 본 연구목적은 심장외막지방의 두께를 측정하여 정상의 수축기 기능인 상태에서 확장기(이완기) 기능장애의 평가와의 연관성을 연구하고자하였다. 연구결과 심장외막지방두께와 이완기 장애 유무가 통계적으로 유의한 수준에서 높은 연관성이 있는 것으로 분석되었다. 특히 심장외막지방두께 측정단면 EAT2에서 측정된 값과 이완기 장애평가방법 E'는 높은 상관관계가 있는 것으로 나타났다. 따라서 심장외막지방두께변화는 좌심실의 이완기능장애를 평가할 수 있는 예측인자로 사용될 수 있을 것으로 사료된다.

육류소비는 가축사육의 비약적인 증가를 초래함과 동시에 조류독감과 구제역 등의 전염병 발병으로 인해 오염된 닭, 오리, 소, 돼지 등이 대량 폐사되는 사례가 늘어나고 있다. 이로 인해 폐사축을 처리 및 처분하여 매몰지를 소멸화 하는 방법들이 강구되고 있다. 그 중 렌더링공정을 이용하여 고온 고압 하에서 폐사축을 전처리하여 발생된 지방을 전이에스테르화하여 바이오디젤을 생산하는 방법이 주목 받고 있는데, 이 역시 바이오디젤을 생산할 수 있는 반면 글리세롤이 폐기물로 발생된다는 단점이 있다. 본 연구는 이 글리세롤을 혐기성 소화의 탄소원과 에너지원으로 사용하여 바이오가스로 전환하는 가능성을 평가하기위해 생화학적 메탄 포텐셜(biochemical methane potential, BMP)테스트를 시행하였다. 반응조 COD농도를 1g으로 설정하고 섭씨 37도 배양기에서 혐기성 입상슬러지를 식종균으로 14일 동안 바이오가스 발생을 모니터링한 결과, 글리세롤로 부터 약 50~58 mL/g COD의 메탄수율 획득이 가능함을 밝혔다. 또한 글리세롤의 바이오가스 전환이 7일 이내에 종료되는 것으로 나타났으며, AI 폐사축으로부터 바이오디젤을 생산 후 나온 부산물인 글리세롤을 자원화하는 혐기성소화 시 메탄생성속도는 7.0~8.3 mL/gCOD･d로 나타났다.

Other phytochemical such as non-saponins of fatty acid has been revealed its bioactive activity including anti-oxidation, whitening, anti-cancer. Supercritical extraction (SE) process mainly refer to the extraction with CO2, is usually from a solid matrix, is a sample preparation step for analytical purposes. SE produce no residual solvent and possess high stability of the extract component, which is advantageous for fatty acid analysis. Methods and Results : Fermented ginseng cultured roots used in the experiment were used for fermentation using Pediococcus pentosaceus. SE performed at different temperature, pressure and extraction time using non-fermented and fermented ginseng roots. Further we fractionated from fermented ginseng using Methanol, Hexane, Ethanol, Ethyl acetate and Butanol. We compared fatty acids contents ginseng extractions by GC analysis. Methyl linoleate contents was 44% of fatty acids supercritical extraction contained. The contents of Methyl linoleate was the most dominant component among 37 types of fatty acids by SE and other extractions solvent. Total fatty acids contents obtained by SE process from fermented ginseng (1325.61ppm) was twice than from non-fermented ginseng (618.47ppm). Conclusion : Fatty acids contents by SE was increased at high pressure. The best condition for fatty acids contents extraction was 60℃, 350bar and 3h.

Background : Despite the presence of various bioactive compounds in ginseng, there is lack of study on the variations of bioactive compounds in ginseng according to the cultivation of soil and the applied fertilizer types (or amount). Therefore, this study aims to examine the variations of 37 fatty acids (FA) and 8 vitamin E (Vit-E) vitamers in 6-year-old ginseng root cultivated in different soil types with different fertilizers regimes. Methods and Results : The profiling of 37 FAs and 8 Vit-E vitamers in 6-year-old ginseng roots was measured by gas chromatography coupled with a flame ionization detector, and then these results were statistically analyzed with chemometrics. The FA and Vit-E content in ginseng roots varied significantly with respect to soil cultivation conditions due to organic fertilizer types and amounts used. Unsaturated FA in ginseng is approximately 2.7 fold higher than the saturated FA. Linoleic, palmitic, and oleic acids were the most abundant FAs found in the ginseng roots. Also, the major Vit-E vitamer found in ginseng root is α -tocopherol. In particular, the application of rice straw compost or food waste fertilizer was increased to create nutritionally-desirable FAs and bioactive Vit-E in ginseng root. In addition, phytonutrient profiling coupled with chemometrics can be used to discriminate the cultivation conditions of ginseng. Conclusion : This preliminary study extends our understanding about the variations of FA and Vit-E in ginseng root depending on cultivation conditions. Hence, these results can be useful as basic information for reliable ginseng production containing high amounts of phytonutrients in a paddy-converted field.

In order to vitalize the local area of Tendou City in Japan, this study chose a local indigenous industry and sought ways to connect the tourism industry with it. An inventory of local indigenous industry was assembled using relevant literature, field surveys, and interviews with local people. The Japanese chess industry was selected for a case study in connecting tourism with industry. Local indigenous industry was defined as an industry related to the local culture that uses local resources (and thus introduces possible industrialization). This industry can be easily marketed is to the rest of Japan or abroad. People in charge of local indigenous industry should understand the meaning and effects of connecting to the tourism industry, while people in tourism should acknowledge that local industry is good marketing material. Three steps are suggested: 1) to display the industrialy process of Japanese chess production: to tourism in safe and comfortable surroundings; 2) to offer amenities and producetion facility tuors; and 3) to offer tourists an opportunity to experience Japanese chess productions first hands.

The objectives of this study were to evaluate the effect of replacing 40% corn meal with three different types of barley (Youngyang, Wooho, and Yuyeon) on the chemical compositions, microbial indices, gas emission, and volatile fatty acid (VFA) content in feces of growing pigs. Sixteen pigs (Landrace × Yorkshire × Duroc) with an initial average body weight of 71 ± 2 kg were maintained in metabolic cages and randomly allotted to four treatments containing different sources of barley, for 23 days. The treatment with three different barley types replacing 40% ground corn showed no effect (P>0.05) on fecal chemical compositions, microbial indices, gas emission, and VFA. However, some differences (P<0.05) were noted in the chemical compositions of crude fiber and ash, and in the levels of Lactobacillus and Salmonella in the feces of the growing pigs. In conclusion, methane and hydrogen sulfide decreased by replacing 40% corn meal with Youngyang and Wooho barley, respectively.
