The steamed and freeze-dried mature silkworm powder (SMSP) is developed by the Rural Development Administration (RDA) in 2012. In here, the nutritional components of SMSP produced by rearing white-silk cocoon silkworm, Baekokjam, at high temperatures were compared and analyzed with those produced under optimal temperature conditions of 25°C. The weight of silkworms reared in a high-temperature environment increased compared to that under an optimal condition. However, when the silkworms matured, the difference in weight according to temperature conditions narrowed. As for the growth rate, the 5th instar silkworms grew a day earlier in a high-temperature environment than in an optimal. SMSPs produced in a high-temperature environment showed a difference when comparing the nutritional components with the SMSPs in an optimal condition. Overall, high-temperature-reared SMSPs contained about twice as high carbohydrates and slightly lower protein and fat than the optimal-reared SMSPs. These results show that SMSPs produced in a high-temperature environment have a difference in growth rate and nutritional composition from those produced under an optimal condition.

연구에서는 '누리금잠'이라 명명된 새로운 누에 신품종을 개발하였으며, 이는 황색 고치와 세리신 고치를 생산 하는 두 개의 기존 계통, 잠311과 D751의 교배를 통해 육성되었습니다. 이 신품종은 첫 교배 실험을 거친 2019년 봄부터 2021년 봄까지 총 4차례의 생산력 평가를 진행했으며, 이어진 2022년 봄부터 2023년 가을까지 4차례에 걸친 지역 적응성 평가를 통해 2023년 가을에 새로운 품종으로 공식 인정받았습니다. '누리금잠'은 봄과 가을 시즌에 각각 평균 부화율 86.9%, 89.6%를 기록하였고, 유충의 평균 성장 기간은 봄에는 21일과 12시간, 가을에는 19일과 22시간으로 나타났습니다. 세리신 고치의 평균 생산성은 봄에 79.17%, 가을에 74.9%였으며, 수확된 세리 신의 평균 중량은 누에고치 250개를 기준으로 봄에 6g, 가을에는 7.7g으로 측정되었습니다. 이와 같은 결과는 '누리금잠'이 높은 부화율과 우수한 세리신 생산성을 갖추고 있음을 시사합니다. 이는 세리 신 기반 제품의 생산 효율성을 증가시킬 뿐만 아니라, 양잠산업의 경제적 가치를 상승시키는 데 기여할 수 있을 것으로 생각됩니다.

코로나바이러스감영증-19 사태가 전세계를 강타하면서, 우리는 기존과 다르게 변해가는 일상 에 적응하는 뉴노멀 시대를 맞이 하였다. 코로나19 이후, 방송, 강의분야 등 문화예술계에도 비대면 문화가 급속도로 확산되고, 방송업계는 랜선방청제도를 도입하여 화상시스템을 통한 온 라인 실시간 방청을 제공하여 관객의 참여를 유도하고 있으며, 강의행사 분야도 화상회의 시 스템을 활용한 진행과 유튜브 플랫폼을 활용한 실시간 송출의 비대면 형태로 진행되고 있다. 이러한 비대면 참여환경은 물리적 스테이지의 한계, 음향 촬영 구도의 아쉬움, 현장감, 생동감 등 몰입적 측면에서의 한계가 존재하고, 언택트 방송 및 공연의 경우 음향과 촬영구도가 아쉬 운 부분으로 꼽히며 현장과의 괴리감, 집중하고 싶은 장면을 선택하여 볼수 없다는 한계도 지 닌다. 비대면 강의 경우에도 일상에서 쉼 없이 이어지는 비대면 참여 환경에 ZOOM Fatigue 라는 신조어가 등장할 만큼 비대면 환경에서의 집중력과 흥미를 잃어가는 현상이 나타나고 있 다. 이처럼 코로나19로 인한 변화가 일상화되면서 인류의 역사는 코로나19 (BC, Before Corona), (AC, After Corona) 나뉠 것이라는 예측이 일기도 한다. 무엇보다 코로나19로 인 해 인류의 정치, 경제, 사회, 문화, 교육등 모든 영역이 대변화를 맞은 가운데 가장 큰 변화는 물리적 접촉이 최소화되면서 Untact문화가 확산됐다는 점이다.

문화유산은 조상들의 문화중에서 후손들에게 물려줄 만한 가치가 있는 것을 말한다.[1] 우리의 문화유산을 우리의 역사, 정체성, 그리고 자부심을 담고 있으며, 이를 통해 우리는 과거의 삶 과 지식, 그리고 경험을 재조명하고 이해할 수 있다. 우리의 문화유산을 보전하고 전파하는 것 은 매우 중요하다. 이를 위해 우리는 문화콘텐츠와 IT기술의 융합적인 미디어아트를 활용하여 이를 알리고자 한다. 이러한 미디어 아트는 국내외 관광객들에게 우리의 문화유산을 소개하는 데 더욱 효과적이다. 전남의 3대 별서정원은 이러한 문화유산 전파의 중요한 장소로서, 다양한 콘텐츠를 통해 우리의 문화유산을 소개하고 있다. 이를 다중디스플레이를 활용한 문화관광 콘 텐츠로 더욱 널리 알리고 우리문화의 보존과 계승에 크게 기여한다.

연중생산이 가능하고 특히, 저온에서 화색발현이 우수하며 볼륨감 있는 스프레이국화 신품종을 개발하기 위하여 충청남 도농업기술원 화훼연구소에서 2010년에 모본으로 황색의 홑꽃 ‘SP09-251-01’를 부본으로 ‘SP08-010-16’계통을 인공수분 하였다. 종자 파종은 2011년에 실시하였고, 실생개체 중 화색과 화형이 우수한 281번째 개체를 선발하여 ‘SP11-103-05’로 계통명을 부여하였다. 주년생산성 검정을 위하여 2011년부터 2013년까지 자연일장, 전조재배, 차광재배를 각각 실시하였고, ‘Yes Holic’과 화형, 화색, 초형이 비슷한 ‘Jazz’ 품종을 대조품 종으로 사용하였다. ‘Yes Holic’ 품종은 2013년에 국립종자원에 품종보호 출원을 하였다. ‘Yes Holic’은 황색(Yellow 7A)의 꽃잎과 녹색(Green 1B)의 화심색으로 조사되었고 자연일장 작형의 개화기는 10월 25일로 ‘Jazz’의 10월 26일에 비해 빨랐다. ‘Yes Holic’의 초장과 줄기굵기는 각각 80.2cm와 6.1mm 로 ‘Jazz’의 78.6cm와 5.3mm보다 컸다. ‘Yes Holic’의 꽃 직경은 4.4cm로 ‘Jazz’의 4.1cm보다 컸으며, 착화수도 ‘Yes Holic’ 가 29.4개로 ‘Jazz’의 22.1개보다 많았다. 흰녹병저항성은 ‘Yes Holic’이 10%이하의 발병율인 3단계로 흰녹병이 저항성이 높은 것으로 확인되었다. 재배상 유의사항은 ‘Yes Holic’은 소등 후 야간온도를 18℃로 가온하면 고유화색 발현과 적당한 착화수 확보 및 균일한 개화가 가능하다. 그리고 여름철 고온기에는 ‘Yea Holic’의 총포에 잿빛곰팡이병이 주로 발생되므로 스크린과 포그를 활용하여 주간온도를 낮추고 봉오리 착색기에 전용 농약을 살포해 주어야 한다.

Recent incidents of state terrorism, including the assassination of Kim Jong-Nam, the murder (and attempted murder) of persons with strong ties to Russia, and the Jamal Khashoggi assassination, demonstrate cruelty while implying the involvement of the state, unlike other acts of terrorism since the Second World War. This trend denies the efforts of the international community, which has suppressed physical punishment including the death penalty in modern times and has achieved advances in human rights and humanitarianism under contemporary international law. Accordingly, this paper utilizes Michel Foucault’s indications regarding prison to reconsider recent cases of state terrorism from a broader perspective while taking into consideration the historical background of conventional terrorism and the development of international terrorism-related treaties.

This study was conducted to examine the effects of the application of familycentered training over the 12-week period by the pediatric physiotherapist on functional balance and activities of daily living in children with cerebral palsy. Among the 26 children with cerebral palsy as the subjects were allocated to the experimental and control group. Both groups were subjected to neurodevelopmental treatment by the pediatric physiotherapist. The experimental group, participated in family-centered training program 3 times a week over a period of 12 weeks for the total of 36 sessions, functional balance and activities of daily living were verified through intergroup comparison. There was no significant difference between the outcomes prior to training and after 6 weeks of training, (p>.05) Pediatric Berg's Balance Scale(PBS) and Functional Independence Measure for children(Wee-FIM) increased significantly from those measures after 6 weeks to those after 12 weeks of training (p<.05). Therefore, these results suggest that on family-centered training on children with cerebral palsy has beneficial effects on functional movements and physical activities.

Protein and polysaccharide are used as many food function including emulsifying and stabilizing agent. Some food emulsions are in low pH such as sorbet ice cream, soft drink, salad dressing etc. According to our previous study was found that fish gelatin (FG) and sodium alginate (AL) mixture provide the information to be a new food emulsifier including at low pH condition (pH 3.5). In addition the study of interfacial rheology has been interested to interpret the formation and stabilization of food emulsion. Then the objective of this study was to investigate the relationship between emulsifying characteristics and interfacial shear rheology of acidified emulsion which was stabilized by FG and AL mixture, compared with a commercial gum arabic (GA). The mixtures of FG and AL were separately prepared with phosphate-citrate buffer at pH 3.5 and 1 %w/v of total concentration. The ratio of FG:AL was 100:0, 80:20, 50:50, 80:20, and 0:100 by weight. They were mixed at 24±2 oC for 90 minutes and kept at the same temperature for 24 hours to reach equilibrium. The emulsion was prepared by adding 1.5 g of olive oil in 100 ml of mixture and homogenized by high speed homogenizer at 10,000 rpm for 10 min at 24±2 oC. The emulsion stabilized with 20:80 showed the best stability after 14 days. The result could be supported by low interfacial tension, high bulk viscosity, and electrostatic repulsion (minus value of electrophoretic mobility). For interfacial shear rheology (storage modulus, G' and loss modulus, G''), G' of 20:80 seem wider liner viscoelastic region which mean more resistance to fracture at interface. While the magnitude of G' and different value of G' and G'' were not difference. In addition, the interfacial shear viscosity of 20:80 also showed high resistance to flow at low shear rate (0.001 - 0.1 s-1). Keywords: Fish gelatin, Sodium alginate, Emulsion, Interfacial shear rheology

Recently, climate change has been increasingly reported to be associated with vector-borne diseases including West Nile Virus, avian poxvirus, bluetongue virus. These diseases, which are of medical and veterinary importance, are known to affect the health status of wildlife. In this sense, it is vital to understand the distribution of mosquitoes and biting midges as the disease-vectors in the habitat of wildlife. In order to do this, nocturnal insects were collected using CDC Mini Night Traps (cat. no. 2836BXQ, BioQuip, CA, USA) in the coniferous and deciduous forest near the ponds in National Institute of Ecology (NIE) on the weekdays from June to September. As a result, 920 mosquitoes belonging to 13 species of 7 genus and 5,129 biting midges belonging to 8 species of Culicoides were collected in total. For mosquitoes, Aedes vexans nipponii and Culex orientalis were the predominant species consisting about two thirds of all the mosquitoes. For biting midges, Culicoides arakawae was the prevalent species present and 97.3% of this kind appeared to have preference to feed on birds. The number of mosquitoes collected remained relatively constant as opposed to the number of biting midges which showed the tendency to fluctuate - the second or third week of each month had the highest number of Culicoides spp. Forest ecology had more diverse distribution of species than livestock farms and reflected the abundance of birds in NIE. In addition, further evaluation of the effect of environment, such as climatic factors, on the ecology of these disease vectors would be required.

In this study, consumer acceptance and sensory intensity evaluations were performed on sponge cakes prepared with domestic and imported cake flours. Specific volume data as well as cross-sectional photograph observations confirmed that the imported flour sample group had greater volume than the domestic flour groups. The imported flour sample group also had a significantly (p<0.05) higher mean overall acceptability score at 5.82; however, it was not significantly different from the domestic white flour sample group (5.40). There was no significant difference in overall texture acceptance between samples prepared with imported and domestic white flours; however, their scores were significantly higher than that of the domestic whole flour group (p<0.05). Consumer acceptances of color significantly decreased as the orders of cake group prepared using the imported, domestic white, and domestic whole flours with the values of 6.48, 5.72 and 4.61, respectively (p<0.05). Acceptance of the air cell and the acceptance and intensity of sweetness did not show significant differences between the imported and domestic white flour group.

Tooth loss in elderly is mainly caused by alveolar bone loss via severe periodontitis. Although the severity of periodontitis is known to be affected by age, the aging process or the genetic changes during the aging of periodontal tissue cells are not well characterized. In this study, we investigated the effect of in vitro aging on the change of gene expression pattern in periodontal fibroblasts. Gingival fibroblasts (GF) and periodontal ligament fibroblasts (PDL) were obtained from two young patients and replicative senescence was induced by sequential subcultivation. When more than 90% cells were positively stained with senescence-associated β-galactosidase, those cells were regarded as aged cells. In aged GF and PDL, the level of phosphorylated retinoblastoma (RB) and p16INK4A protein was significantly decreased and increased, respectively. However, the protein level of p53 and p21, well known senescence-inducing genes, did not increase in aged GF and PDL. Although P27Kip1 and p15INK4B, another cyclin-dependent kinase inhibitors, were reported to be involved in replicative senescence of human cells, they were decreased in aged GF and PDL. Because senescent cells showed flattened and enlarged cell shape and are known to have increased focal adhesion, we examined the protein level of several integrins. Aged GF and PDL showed increased protein level of integrin α2, αu, and β1. When the gene expression profiles of actively proliferating young cells and aged cells were compared by cDNA microarray of 3,063 genes and were confirmed by reverse transcription-polymerase chain reaction, 7 genes and 15 genes were significantly and commonly increased and decreased, respectively, in aged GF and PDL. Among them, included are the genes that were known to be involved in the regulation of cell cycle, gene transcription, or integrin signaling. The change of gene expression pattern in GF and PDL was minimally similar to that of oral keratinocyte. These results suggest that p16INK4A/RB might be involved in replicative senescence of periodontal fibroblasts and the change of gene expression profile during aging process is cell type specific.
