Purpose – The paper aims to develop the theory of TAM and perceived risk through a more comprehensive and rigorous understanding of the influencing factors of the consumer’s adoption of LG HomNet smart home from the perspective of trade-offs. Design/methodology – Based on the TAM and perceived risk theory, combined with the individual characteristics of consumers in the context of information technology as the external factors of the technology acceptance model, this paper constructs a theoretical model of the factors affecting the use intention of the consumer. It was empirically tested by using SEM, and survey data was collected from 458 respondents. Findings – The research results show that 9 hypotheses of the research model are supported and have reliable prediction accuracy. Consumers’ perceived interest, perceived connectivity and perceived controllability have a significant positive impact on their intention to use. In addition, this paper also confirmed the mediating effect of perceived usefulness and perceived ease of use. Originality/value – Consumers are very concerned about gains and losses. Low-level performance risks, security risks, and financial risks will drive the consumer to have a stronger intention to use, and financial risks have the strongest impact. This research provides a useful implication and guidance for smart home equipment manufacturers and service providers in product and service innovation and marketing and promotion strategies.

‘반(半)도시화’ 중국농민공들의 난제 및 시민화에 필요한 입법

황해흠 ( Huang Haixin ),조동제 ( Cho Dong-je ) 경상대학교 법학연구소 2021 法學硏究 Vol.29 No.1

중국에서 개혁개방 정책을 실시한 이후, 많은 수의 농민공은 도시에 진출하게 되었고, 그들은 중국사회의 도시화 및 공업화 발전 그리고 현대화 건설을 위해 크나큰 공헌을 하였다. 하지만 현재 농민공은 도시의 시민도 아니고 진정한 농민도 아닌 ‘반(半)도시화’라는 난감한 처지에 처해져 있다. 이들은 지역과 직업의 변화만 있을 뿐, 사회적 신분은 여전히 농민으로 되어 있으며, 국민으로서의 마땅한 대우를 누리지 못하고 있다. 또한 이들은 현대도시의 행동양식과 가치적 이념이 제대로 형성되지 않은 채 시종일관으로 도시로 부터 방치되어 있다. 중국 농민공 문제는 수억 명의 농민공 및 가족들의 권익과 밀접하게 관계되는 문제이면서 경제이익, 사회권익, 정치권력 및 문화융합 등 종합적인 문제도 내포하고 있다. 본 논문은 중국의 현실에 근거하여, 중국 특유의 농촌인구 유동 과정과 중국 농민공의 실생활 현황에 대한 고찰을 통해 제도적 원인, 농민공의 자체적 원인과 사회적 원인 등 3가지를 분석 및 고찰하여 ‘반(半)도시화’가 형성된 원인에 대하여 설명하는데 있다. 또한 농민공의 취업, 사회적 보장과 공공서비스, 문화와 정치생활 등에 있어서의 현재 ‘반(半)도시화’로 직면하고 있는 난제에 대해서도 분석하고 있다. 기존의 연구 결과에 의하면 농민공이 시민화하는 과정에서 가장 큰 영향을 미치는 요인은 도시와 농촌의 이원적 체제이다. 이러한 이원적 체제가 초래한 결과인 이원적 토지, 호적, 취업, 사회보장 등에 있어서의 제도적 미비와 불공정함이 농민공의 시민화 과정에서 주요한 장애로 여겨지고 있다. 그러므로 이에 관련된 연구를 통하여 농민공의 ‘반(半)도시화’에 놓인 어려움을 해결하는데 있으며, 동시에 농민공의 시민화를 실현하는데 그 취지를 두고 있다. Since China implemented reform and opening-up policy, large quantities of migrant workers have entered into the cities, and they have made great contribution to China’s urbanization, industrialization and modernization. But they are in the embarrassed condition of half-urbanization between city and countryside. They only changed the region and occupation, social identity is still the farmers. They can’t enjoy the national treatment, also did not form the behavior and value concept of modern city, always on the edge of the city. The problem of Chinese migrant workers is closely related to the rights and interests of hundreds of millions migrant workers and their families, and also includes comprehensive problems such as economic benefits, social rights, political power and cultural convergence. This article from the reality of China, through the investigation on the rural population flow and living situation of migrant workers in China, from the three aspects of employment, social security and public services, cultural and political life, analyzes the predicament of semi urbanization, and then from the three aspects of the institutional factors, migrant workers’ own factors and social factors, analyzes the reasons for the formation of semi urbanization. The urban-rural dual system is the biggest influencing factor in the citizenization process of migrant workers. Due to the urban-rural dual system, dual land, household registration, employment, social security and other systems are the major obstacle to the citizenization of migrant workers. On the basis of research and analysis, this dissertation gives aspects of suggestions on the legal construction, to provide theoretical reference for the citizenization process of migrant workers and realize the real citizenization of migrant workers.

Mitochondrial-Targeted Polyethylenimine Functionalized Graphene Oxide Nanocarrier and Its Anti-Tumor Effect on Human Lung Carcinoma Cells

Mei Jin,Zhiming Liu,Wen Zhang,Haixin Dong,Fang Zhou,Jianfeng Yu,Xinpeng Wang,Zhouyi Guo 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.8

Graphene oxide nanosheet (NGO) was covalently functionalized with positively charged, branched polyethylenimine (bPEI) via an amide bond, coated with serum proteins by electrostatic interaction. Operating as a newly fashioned, multifunctional nanocarrier, the processed NGO showed promise for use in combined gene therapy, chemotherapy, photothermal therapy, bioimaging and as a biosensor of cancer cells. Our current research is focused on the systematic studies of mechanisms of cancer cellular uptake, subcellular location, cytotoxicity and the cellular exclusion of the NGO–bPEI nanocarriers. It was observed that NGO–bPEI accumulated in the mitochondria and that long-term retention of NGO–bPEI led to a decrease in mitochondrial membrane potential while levels of reactive oxygen species increased. The mitochondrial effects associated with long-term retention of NGO–bPEI have potential as a synergistic enhancer of the cytotoxic effects of anti-cancer drugs or genes in human lung carcinoma (A549) cells. This work demonstrated the utility of NGO–bPEI-based multifunctional nanocarriers while detailing the mechanism at the cellular level and providing guidance for further research in cancer therapy.

Background: Hepatic lipid disorder impaired mitochondrial homeostasis and intracellular redox balance, triggering development of non-alcohol fatty liver disease (NAFLD), while effective therapeutic approach remains inadequate. Ginsenosides Rc has been reported to maintain glucose balance in adipose tissue, while its role in regulating lipid metabolism remain vacant. Thus, we investigated the function and mechanism of ginsenosides Rc in defending high fat diet (HFD)-induced NAFLD. Methods: Mice primary hepatocytes (MPHs) challenged with oleic acid & palmitic acid were used to test the effects of ginsenosides Rc on intracellular lipid metabolism. RNAseq and molecular docking study were performed to explore potential targets of ginsenosides Rc in defending lipid deposition. Wild type and liver specific sirtuin 6 (SIRT6, 50721) deficient mice on HFD for 12 weeks were subjected to different dose of ginsenosides Rc to determine the function and detailed mechanism in vivo. Results: We identified ginsenosides Rc as a novel SIRT6 activator via increasing its expression and deacetylase activity. Ginsenosides Rc defends OA&PA-induced lipid deposition in MPHs and protects mice against HFD-induced metabolic disorder in dosage dependent manner. Ginsenosides Rc (20mg/kg) injection improved glucose intolerance, insulin resistance, oxidative stress and inflammation response in HFD mice. Ginsenosides Rc treatment accelerates peroxisome proliferator activated receptor alpha (PPAR-α, 19013)-mediated fatty acid oxidation in vivo and in vitro. Hepatic specific SIRT6 deletion abolished ginsenoside Rc-derived protective effects against HFD-induced NAFLD. Conclusion: Ginsenosides Rc protects mice against HFD-induced hepatosteatosis by improving PPAR-α-mediated fatty acid oxidation and antioxidant capacity in a SIRT6 dependent manner, and providing a promising strategy for NAFLD.
