Upregulation of the nutritional value of feed is the major target of various studies in the livestock industry, and dietary enzyme supplementation could aid in digesting the nondegrading nutrients of grains in feed ingredients. Dried distillers' grains with solubles (DDGS) is a byproduct of the fermentation process in the beverage industry and can be used as a large supply source of fiber in feed. Therefore, we conducted an experiment with male broiler chickens to investigate the effect of various types of enzymes on DDGS and compare the efficacy of single enzyme and multienzyme complexes on growth performance and gut environments in broiler chickens. We used 420 1-day-old broiler chickens (Ross 308), and they were allotted into 4 dietary treatments with seven replications (CON, corn-soybean meal [SBM] diet; NC, DDGS supplemented diet; SE, 0.05 % of mannanase supplemented DDGS-based diet; MC, 0.10% of multienzyme complex (mannanase and xylanase, glucanase) supplemented DDGS-based diet. The dietary exogenous enzyme in the DDGS-supplemented diet could improve growth performance as much as the growth of the control group, and digestibility of dry matter, crude protein, and gross energy were significantly increased by enzyme addition in groups of chicks fed DDGS-supplementation diet. Moreover, the populations of pathogenic bacteria, coliforms, and Bacteroidetes were significantly decreased by enzyme supplementation, which might lead to improved gut mucus-secreting cells and inflammatory cytokines in the jejunum. Collectively, dietary single enzyme and multienzyme complexes could improve gut environments, including intestinal immune responses and gut microbial population, and lead to improvement of growth performance in broiler chickens.

Purpose: Ketogenic diets (KDs) have anti-obesity effects that may be related to glucose control and the gut microbiota. This paper hypothesizes that KD reduces body weight and changes the insulin sensitivity and gut microbiota composition in a mouse model of diet-induced obesity. Methods: In this study, C57BL/6 male mice were assigned randomly to 3 groups. The assigned diets were provided to the control and high-fat (HF) diet groups for 14 weeks. The KD group was given a HF diet for 8 weeks to induce obesity, followed by feeding the KD for the next 6 weeks. Results: After the treatment period, the KD group exhibited a 35.82% decrease in body weight gain compared to the HF group. In addition, the KD group demonstrated enhanced glucose control, as shown by the lower levels of serum fasting glucose, serum fasting insulin, and the homeostatic model assessment of insulin resistance, compared to the HF group. An analysis of the gut microbiota using 16S ribosomal RNA sequencing revealed a significant decrease in the proportion of Firmicutes when the KD was administered. In addition, feeding the KD reduced the overall alpha-diversity measures and caused a notable separation of microbial composition compared to the HF diet group. The KD also led to a decrease in the relative abundance of specific species, such as Acetatifactor_muris, Ligilactobacillus_apodemi, and Muribaculum_intestinale, compared with the HF group. These species were positively correlated with the body weight, whereas the abundant species in the KD group (Kineothrix_alysoides and Saccharofermentans_acetigenes) showed a negative correlation with body weight. Conclusion: The current study presents supporting evidence that KD reduced the body weight and altered the insulin sensitivity and gut microbiota composition in a mouse model of diet-induced obesity.

The purpose of this study was to analyze the form and meaning of shaman's costumes worn by each gutgeori in Seoul jaesugut and to derive the characteristics of Shaman's costume at gutgeori. Observational research was conducted for three years by participating in the site of two types of gut, which are divided into local jaesugut for the well-being of the region and individual jaesugut that takes place based on personal request. Seoul jaesugut consists of 12 different gutgeori according to the deity it serves and meaning: Bujeongcheongbae, Gamangcheongbae, Bulsageori, Sangeori, Josanggeori, Sangsangeori, Byulsanggeori, Sinjanggeori, Daegamgeori, Seongjugeori, Changbugeori, and Duitjeon. The shape and colour of the shaman's costume worn in each gutgeori are related to the meaning of the gutgeori. Followings are the characteristics of the shaman's costume from gutgeori. First, shaman's costume adopted traditional costumes that symbolized the characteristics of god represented in each gutgeori. Second, gutgeori consists of multiple gods, and shaman's costumes were adopt to represent the superior god among these gods. Third, sometimes the costumes were adopted according to the characteristic of the god instead of its divinity. Fourth, even if the gods were different, if the roles of the gods were the same, the same form of shaman's costume could be taken. Fifth, the process of gut showed the harmony of yin and yang using the principle of five elements through the colour of shaman's costume.

To understand the diet of chaetognaths, the gut content and fatty acid trophic makers (FATMs) of Sagitta crassa and S. nagae, which are the most predominant species of chaetognath in the Yellow Sea, were analyzed. Gut contents of the two species examined by microscopic analysis revealed that copepods are the major components of the diet (> 70% of gut contents) and there was no significant changes in the gut contents of two species collected in spring and summer season. Although 16:0, 20:5(n-3) (Eicosapentaenoic acid) and 22:6(n-3) (Docosahexanoic acid), which are known as phytoplankton FA markers, were the most dominant among the fatty acids in both chaetognath species, the detection of copepod FA markers, 20:1(n-9) (Gadoleic acid) and 22:1(n-11) (Cetoleic acid), provided evidence that their food sources include copepods. These results suggest that S. crassa and S. nagae are carnivores and mainly feed on copepods in the Yellow Sea.

이 글은 굿의 공연화 방법을 모색하기 위하여 시작되었다. 그 방법을 찾기 위해 먼저 지금까지 이루어졌던 굿공연을 정리해야 했다. 무엇보다 공연의 미덕은 '다양성 창출'이라고 생각하기에 기존의 공연 문법을 정리하고, 이와는 다른 길을 모색하기 위함이었다. 그러나 1980년대부터 본격화된 굿공연을 정리하는 것은 생각보다 쉽지 않은 일이었다. 기존에 한 번도 정리되지 않았기 때문이다. 그러기에 본 연구자의 직 간접적인 경험에 의거하여 중요한 공연들을 시대순으로 정리해보았다. 무엇보다 공연을 가능케 하는 것은 그 공연의 기획자(때론 개인이 아닌 그룹일 수 있고, 때론 기관이다)이기에 이들을 주목하였다. 전국민속예술경연대회, 공간사랑, 굿학회, 마당세실극장, 서울놀이마당, 국립국악원이 굿공연의 중심 공간 및 기획 주체였다. 굿공연사 기술은 그 자체로 가치있는 작업이다. 그러나 이 작업은 개인의 노력으로 하기에는 방대한 작업이며, 그 가치의 확산을 위해서는 공공프로젝트로 진행해야 한다. 이에 본고는 이에 대한 필요성을 제기하고 있다. 한편 본고는 앞서 말했듯이 굿의 공연화 방법을 모색하기 위한 전제조건으로 굿공연사를 기술했다. 시론적으로나마 굿공연사를 정리하니 대부분의 공연이 굿을 하는 이들이 공연 주체가 되었고, 그로 인하여 굿공연의 방식은 원래의 굿을 그대로 시간에 맞추어 실연하는 방식을 크게 벗어나지 못함을 알게 되었다. 이에 굿을 소재로 다른 방식의 공연을 하는 마당극패 신명과 연희패 The광대의 작업을 소개하였다. 이를 통해 총체적으로 얽혀있는 굿의 공연요소들이 잘 가공된다면 굳이 '재현'의 방식이 아닌, 새로운 공연으로의 소재나 메타포가 될 수 있을 것으로 기대하였다.

The stomach has emerged as a crucial endocrine organ in the regulation of feeding since the discovery of ghrelin. Gut-derived hormones, such as ghrelin and cholecystokinin, can act through the vagus nerve. We previously reported the satiety effect of hypothalamic clusterin, but the impact of peripheral clusterin remains unknown. In this study, we administered clusterin intraperitoneally to mice and observed its ability to suppress fasting-driven food intake. Interestingly, we found its synergism with cholecystokinin and antagonism with ghrelin. These effects were accompanied by increased c-fos immunoreactivity in nucleus tractus solitarius, area postrema, and hypothalamic paraventricular nucleus. Notably, truncal vagotomy abolished this response. The stomach expressed clusterin at high levels among the organs, and gastric clusterin was detected in specific enteroendocrine cells and the submucosal plexus. Gastric clusterin expression decreased after fasting but recovered after 2 hours of refeeding. Furthermore, we confirmed that stomachspecific overexpression of clusterin reduced food intake after overnight fasting. These results suggest that gastric clusterin may function as a gut-derived peptide involved in the regulation of feeding through the gut-brain axis.

이글에서는 강신무굿인 서울굿과 황해도굿, 세습무굿인 경기도당굿과 남해안별신굿의 장단 활용 양상을 살핀 후 이를 바탕으로 무당굿 장단 활용의 보편성을 살폈다. 동해안굿이나 호남굿의 장단 활용 양상까지 살펴야 마땅하자 그렇지 못한 것은 이글의 한계이다. 다만 보편성을 살피면서 동해안굿의 사례 몇 가지를 언급은 했으나 동해안굿 장단 활용 양상도 살펴야 이 글의 논지가 더 충실해질 것으로 기대한다. 이를 통해 지역별로 연행 집단, 연행 양상 등이 달라 보이지만, 실상 보편적인 원리는 같을 수도 있다는 것을 제시하려 했다. 각 지역별 굿에 사용하는 장단은 분명한 나름의 체계를 가진다. 연행자와 연행방식에 따라 사용하는 장단이 다르다. 그런데 이렇게 사용하는 장단의 체계는, 장단의 명칭이나 구성 등에서는 독자성이 보이지만, 다른 지역의 굿과 비교하면 공통점이 많다. 여기서는 이를 일러 보편성이라고 했다. 이는 한국의 굿거리 짜임이나 연행방식, 장단의 활용 등에서는 상당한 차이가 있지만, 장단 체계만큼은 동일하다는 의미이다. 다음으로 연행자에 따라 장단의 활용양상이 다른 것도 지역적인 보편성이다. 서울굿에서는 장구재비가 앉은 굿을 하면서 직접 무가를 부르는 경우와, 무당이 선굿을 하는 경우에 따라 장단의 활용이 다르다. 연행자에 따른 장단의 활용이 뚜렷하게 구분되는 것은 경기도당굿이 대표적이다. 미지와 산이가 연행하는가에 따라 장단이 달라진다. 아울러 장단의 활용을 통해 굿거리 연행의 의미를 전달하는 것도 공통된다. 청신과 오신의 의미를 장단을 통해 나타내는 것은 모든 지역굿에서 확인된다. 그리고 이는 몇몇 장단이 신령의 위상과 긴밀한 관련을 가지고 있음을 나타내는 데 보다 분명하게 드러난다. 서울굿에서는 상산장단과 별상장단이라는 이름처럼, 신령의 이름이 곧장 장단명으로 사용되기도 하고 모든 지역의 굿에서 수비를 물리는 의미를 장단의 활용을 통해 드러낸다. 지역별로 굿의 연행 양상은 다르지만, 굿판의 주체인 신령을 인식하고 있다는 의미이다. 비록 세습무들의 굿이 강신무의 굿보다는 신령에 대한 인식이 드러나지 않고, 신력(神力)을 드러내는 다양한 연행 요소는 없지만 신령에 대한 인식이 있음이 장단 활용을 통해 나타내는 것이다.

The human-associated microbiota is diverse, varies between individuals and body sites, and is important in human health. Microbes in human body play an essential role in immunity, health, and disease. The human microbiome has been studies using the advances of next-generation sequencing and its metagenomic applications. This has allowed investigation of the microbial composition in the human body, and identification of the functional genes expressed by this microbial community. The gut microbes have been found to be the most diverse and constitute the densest cell number in the human microbiota; thus, it has been studied more than other sites. Early results have indicated that the imbalances in gut microbiota are related to numerous disorders, such as inflammatory bowel disease, colorectal cancer, diabetes, and atopy. Clinical therapy involving modulating of the microbiota, such as fecal transplantation, has been applied, and its effects investigated in some diseases. Human microbiome studies form part of human genome projects, and understanding gleaned from studies increase the possibility of various applications including personalized medicine.
