Metal ion-induced and it’s regulatory genes were screened in virulent salmonella typhimurium UK1 and tested cross-regulation with various stresses. Using the techniqud of P22-MudJ(Km, lacZ)-directed lacZ operon fusion, LF40 cuiA::MudJ and Lf153 cuiD::MudJ which were induced by copper were selected. cuia and cuiD were determined anaerobic coper inducible and copper tolerance response gene, respectively. Also cuiA and cuiD locus were determined at 81 and 8min, respectively, on salmonella Genetic Map. The two regulators were identified as cuaR, and cudR, which controls cuiA and cuiD, respectively. cuaR, and cudR appeared as negative regulators because the expression of cuiA-lac-Z and cuiD-lacZ were increased. Copper adapted UK1 showed high resistance to H$_{2}$O$_{2}$, but cuiD did not. The product of the cudR locus was responsible for decreasing the tolerance to copper and H$_{2}$O$_{2}$. Furthemore cuiA and cuiD locus were found to be part of a regulon under the control of a trans-acting regulators, rpoS, oxyR and relA. Therefore, the results suggest CTR participate with oxidative stress on Salmonella.

This study examines the impact of perceived risks for smart shoes based on purchase intention by type of smart shoes as well as how they are mediated by fashion innovativeness and technology innovativeness. It also compares the differences between awareness, interest and perceived risk of smart shoes by gender and age. This study was conducted based on men and women in their 20s to 50s who provided 246 samples for data analysis using SPSS 25.0. The results show significant differences in the awareness, interests and perceived economic risk of smart shoes by gender and age. The perceived performance risk had a positive effect on the purchase intention of smart shoes for GPS. Perceived aesthetic-psychological risk had a negative effect on all types of smart shoes. Perceived economic risk had a negative effect on the purchase intention of smart shoes for entertainment; in comparison, perceived social risk had a positive effect on the purchase intention of smart shoes for GPS and entertainment. Fashion innovativeness and technology innovativeness also mediated the relationship between perceived economic risk as well as the purchase intention of smart shoes for healthcare, GPS and entertainment.

강원도 남북교류협력현황 분석 및 발전방안 모색

정주리(Ju-ri Jung),조은설(Eun-seol Cho) 강원행정학회 2011 한국행정과 정책연구 Vol.9 No.1

지방자치단체의 남북교류는 중앙정부와는 달리 비정치적인 분야에서의 교류와 협력이 가능하다는 점에서 큰 의미를 가지고 있다. 하지만 북핵문제, 천안함 피격사건 이후 남북교류협력를 바라보는 국내외의 시각에 많은 변화가 일어나고 있다. 즉, 최근의 국내외 정세에 영향을 받아 남북 교류협력 추진이 다소 경직되어 있는 상황이다. 본 연구에서는 지방자치단체의 남북교류협력 사업의 개념과 의의 및 강원도의 남북교류협력사업의 현황을 분석하고, 이를 바탕으로 향후 지방 자치단체 교류협력을 발전시키기 위한 방안을 탐색하였다. 남북 교류협력 활성화를 위해서는 적합한 사업의 선정, 공동협력 및 개방화, 지방정부의 전문성 제고, 공동발전계획의 수립 등에 대한 고려가 필요하다. 남북교류협력 활성화를 위해서는 지자체간 공동협력사업의 추진이 필요하므로 효율적이고 남북한 모두에게 이득이 되는 사업추진을 위해 경제협력, 환경분야 협력, 인적문화적 교류 분야차원에서 방안을 모색해 보았다. Mutual exchange between local governments in South and North Korea has very important implications because, unlike the case of the respective central governments, there is greater scope for cooperation in nonpolitical areas. But there have been many changes in the exchange and cooperation project between South Korea and North Korea, since the North Korean nuclear issue and North Korea’s provocations. Influenced by recent foreign and domestic affairs inter-Korea exchange and cooperation project was somewhat inflexible. This study explored concept of North-South exchanges and cooperation in local governments, and analysis of Gangwon Province’s Inter-Korea Exchange Cooperation Project, and seeks to methods for developing exchanges and cooperation in the Korean Peninsula. In order to activate exchanges and cooperation between South and North, there are in need of selection of a suitable project, collaboration and openness, enhancing the expertise of local government, the establishment of a joint development plan. Inter local governments need to cooperation in order to enable cooperation in South and North Korea. The study has been seeking an alternative dimension in economic cooperation, environmental cooperation, human and cultural exchanges for beneficial to both North and South Korea.

패션산업의 환경은 인간 고관여의 생산 프로세스에서 벗어나 IT 및 인공지능 기반의 자동화된 생산 프로세스로 급속히 변화하고 있다. 이에 본 연구에서는 4차 산업혁명에 따른 패션디자인 환경의 변화를 인공지능 기반의 혁신 사례를 중심으로 고찰하고, 그 특성을 도출하는데 목적이 있다. 사례 고찰 결과 현재 글로벌 IT 기업을 중심으로 인공지능 디자이너 개발이 활발히 이루어지고 있으며, 인공지능 기반의 패션 디자인 프로세스는 기술 혁신, 디자인 혁신, 프로세스 혁신의 특성을 내포한다. 인공지능 디자이너 작업의 수준은 아직 단독으로 디자인 개발을 진행하는 것에는 부족함이 있는 것으로 나타나지만, 현재 진행 중인 기술 개발 수준으로 보아 인공지능의 완성도 있는 디자인 제작이 신속히 이루어질 것으로 전망된다. 이로써 기존의 패션 디자인 프로세스에 도출되는 변화로는 올 인원 디자인 기획, 개인 맞춤 디자인, 저관여도 의류자동 제작으로 나타나며, 패션 기업 및 브랜드는 이에 주목하여 향후 기업 전략을 세워야 할 필요가 있다. The environment of fashion industry is rapidly changed from the human-involved production process to IT and AI-based automatic production process. The present study thus aims to examine the change in the environment of fashion design resulting from the fourth industrial revolution among AI-based innovative cases, and further draw its characteristics. After examining cases, it was found that AI designer development is currently performed among global IT firms. AI-based fashion design process involves characteristics such as technological innovation, design innovation, and process innovation. Although the level of AI designer work is shown to be inadequate yet for the exclusive implementation of developing design, complete AI design production is expected to be done swiftly considering the level of ongoing technological development. In this way, changes drawn to the previous fashion design process include all-in-one design planning, customized design, and automatic low involvement clothing process. Fashion companies and brands need to focus on it and set up further corporate strategies.

각 돈피추출물의 수율과 단백질함량은 고분자 PS 처리구에서 높은 함량을 나타내었으며, 특히 단백질 함량은 저분자 LPS 처리구에 비해 유의적으로 높았고, 약 10배 정도의 높은 단백질 함량을 나타내었다(p<0.05). 항산화활성 측정결과 처리 농도가 증가할수록 높은 항산화 활성을 나타내었으며(p<0.05), 특히 고분자 PS 처리구에 비해 저분자 LPS 처리구에서 유의적으로 높은 효과를 나타내었다. ORAC 활성은 LPS 농도 1 mg/mL일 때, $141.39{\mu}M$ TE/g의 높은 활성을 나타내었다. 각 돈피추출물을 신경모세포종 SH-SY5Y 세포에 고농도로 처리한 결과 세포에 독성을 나타내지 않았다. 신경세포에 과산화수소를 처리하여 유발시킨 산화적 스트레스에 대한 PS와 LPS의 신경세포 보호효과를 확인한 결과, 모든 처리구에서 농도 의존적으로 세포 보호효과를 나타내었다. 특히 저분자인 LPS 처리구 농도 $100{\mu}g/mL$일 때, 86.45%의 세포생존율을 보였으며 $H_2O_2$ 대비 29.98%의 신경세포보호효과를 나타내었다. 독성 단백질인 $A{\beta}_{1-42}$를 처리하여 신경세포 보호효과를 확인한 결과, 고분자 PS 처리구보다는 저분자인 LPS 처리구 농도 $100{\mu}g/mL$일 때, 82.01%의 생존율을 보였으며 $A{\beta}_{1-42}$ 대비 14.38%의 신경세포보호효과를 나타내었다(p<0.05). AChE 저해효과를 확인해 본 결과, 고분자 PS 처리구에서는 거의 효과가 나타나지 않았으나, 저분자인 LPS 처리구에서는 농도 의존적으로 증가하는 경향을 나타내었으며, 농도 100 mg/mL일 때 33.62%의 높은 저해 효과를 나타내었다. 따라서 본 연구결과 돈피에서 분리한 3 kDa 이하의 저분자 효소분해물인 LPS는 높은 항산화 활성을 나타내었고, $H_2O_2$와 $A{\beta}_{1-42}$로 유발시킨 산화스트레스에 대한 신경세포 보호효과 및 AChE 저해 효과를 나타내어 향후 항산화 활성 및 신경세포보호를 위한 축산식품 소재로 이용 가능성이 있을 것으로 판단된다. This study was conducted to determine the antioxidative and neuroprotective effect of pig skin extracts (PS) and pig skin gelatin hydrolysates (LPS) using a human neuroblastoma cell line (SH-SY5Y). The extraction yield of PS was 3 fold higher than that of LPS. The protein content of PS was about 10 fold higher than that of LPS (p<0.05). Also LPS increased antioxidative activity dose dependently, and the activity was significantly higher than PS at all concentration (p<0.05). DPPH radical scavenging activity of LPS at 50 mg/mL was 92.97%, which was similar to $1{\mu}M$ vitamin C as a positive control. ABTS radical scavenging activity of LPS (20 mg/mL) was 89.83% and oxygen radical absorbance capacity of LPS at 1 mg/mL was $141.39{\mu}M$ Trolox Equvalent/g. No significant change of human neuroblastoma cells was determined by MTT test. Cell death by oxidative stress induced by $H_2O_2$ and amyloid beta 1-42 ($A{\beta}_{1-42}$) was protected by LPS rather than PS. Acetylcholine esterase was significantly inhibited, by up to 33.62% by LPS at 10 mg/mL. Therefore, these results suggest that pig skin gelatin hydrolysates below 3 kDa have potential to be used as anti-oxidative and neuroprotective functional additives in the food industry, while further animal test should be determined in the future.
