여성 직장인의 개인생활 및 직장생활 만족도에 영향을 미치는 요인에 관한 탐색적 연구
No full text오늘날 저출산, 고령화 등으로 인해 생산가능인구가 점차 감소함에 따라 여성의 경제활동 참여가 증가하고 있다. 하지만 아직까지도 여성의 직장생활에 대한 부정적인 사회적 인식뿐만 아니라, 여성은 가정과 직장 사이에서 요구되는 역할 갈등 때문에 이중 부담을 겪고 있다.
이에 따라 본 연구는 여성 직장인의 개인생활 및 직장생활 만족도에 영향을 미치는 다양한 요인에 관한 탐색적 연구를 수행하였다. 분석을 위해 한국여성정책연구원의 여성관리자패널조사(Korean Women Manager Panel) 데이터를 활용하였으며, 2014년과 2016년의 1,196개 패널 데이터를 선정하여 분석하였다.
분석 결과, 목표 지위, 조직 내외 멘토 유무, 비공식적 모임 여부, 직장생활에 대한 배우자의 태도는 개인생활 및 직장생활 만족도에 모두 긍정적인 영향을 미치는 것으로 나타났다. 그리고 급여/임금에 대한 차별 경험은 개인생활 및 직장생활 만족도에 모두 부정적인 영향을 미쳤으나, 부서/업무 배치, 교육훈련, 인사고과에 대한 차별 경험은 오직 직장생활 만족도에만 부정적인 영향을 미치는 것으로 나타났다. 자녀가 있는 여성 직장인의 경우에는 오직 개인생활 만족도에만 부정적인 영향을 미쳤다.
본 연구는 여성 직장인의 개인생활 및 직장생활 만족도에 영향을 미치는 요인에 대해 개인, 직장 및 기타 등의 측면에서 분석하였다는 점에서 그 의의가 있으며, 향후 여성 직장인과 관련된 연구 수행 및 정책/전략 수립 시 활용 가능할 것이다
청소년의 창의성 향상을 위한 게이미피케이션 설계 방안: ‘아이디어 리그’ 및 ‘아이디어 컴퍼니’ 사례
No full text본 연구는 ‘아이디어마루’ 플랫폼에서 미래 창업의 주역인 청소년의 창의성을 향상하기 위해 ‘아이디어 리그’ 및 ‘아이디어 컴퍼니’를 설계한 사례를 제시하였다. ‘아이디어 리그’는 창의성이 필요한 질문에 대해 청소년들이 아이디어를 제안하는 서비스로, 아이디어의 순위를 경쟁하거나 다른 아이디어를 직접 평가하는 재미를 느낄 수 있다. 그리고 ‘아이디어 컴퍼니’는 청소년들이 가상기업을 설립하는 서비스로, 설립한 가상기업에 대해 멘토링 및 모의투자를 받을 수 있다. 본 연구 결과는 비게임 분야에도 게이미피케이션이 적용될 수 있음을 제시하였고, 게임에 대한 긍정적인 인식을 확산하는데 기여할 것이다
Government R&D Subsidy and Additionality of Biotechnology Firms: The Case of the South Korean Biotechnology Industry
No full textGovernment R&D subsidies are more important in latecomer countries of biotechnology industry, where venture capital has not been developed, and ratio of start-ups is high.
Previous studies were limited to the promotion of input and output, such as private R&D investment and performance, through government R&D subsidies.
However, these studies cannot reflect the change of a firm’s behavior (or strategy) by a government R&D subsidy.
Therefore, this study extensively investigated the effects of government R&D subsidies in multifaceted aspects of input, output, and behavioral additionality.
By adopting the propensity score matching (PSM) method, we found firms benefiting from government R&D subsidies had marked higher R&D investment
in terms of input additionality and produced more technological innovation within a short period in terms of output additionality, although financial performance was not determined.
Moreover, government R&D subsidies have accelerated strategic alliances and suppressed external financing in terms of behavioral additionality
Role of quantum confinement in 10nm-scale perovskite optoelectronics
No full textQuantum confinement-driven band structure engineering of metal halide perovskites (MHPs) is examined for realistically sized structures that consist of up to 105 atoms. The structural and compositional effects on band gap energies are simulated for crystalline CH3NH3PbX3 (X = I/Br/Cl) with a tight-binding approach that has been well-established for electronic structure calculations of multimillion atomic systems. Solid maps of band gap energies achievable with quantum dots, nanowires, and nanoplatelets concerning sizes, shapes, and halide compositions are presented, which should be informative to experimentalists for band gap designs. The pathway to suppress band gap instability that appeared in mixed halide perovskites is proposed, revealing that the red shift induced by halide phase separation can be hugely diminished by reducing sizes and adopting halides of lower electronegativity. Our modeling results on finite MHP structures of over 10 nm dimensions show a blueprint for designs of stable light-emitting sources with precisely controlled wavelengths.[FIG OMISSION
Shank3 regulates striatal synaptic abundance of Cyld, a deubiquitinase specific for Lys63-linked polyubiquitin chains
No full textAbstractThe SH3 and multiple ankyrin repeat domains 3 (Shank3) proteins are core organizers of the postsynaptic density in neuronal excitatory synapses, and their defects cause various neurodevelopmental and neuropsychiatric disorders. Mechanistically, Shank3 directly and indirectly interacts with hundreds of synaptic proteins with diverse functions and potentially exerts its regulatory roles in synaptic development and function via these interactors. However, Shank3‐dependent regulation of synaptic abundance has been validated in vivo for only a few Shank3 interactors. Here, using a quantitative proteomic analysis, we identified 136 proteins with altered synaptic abundance in the striatum of Shank3‐overexpressing transgenic (TG) mice. By comparing these proteins with those found in a previous analysis of the postsynaptic density of Shank3 knock‐out (KO) striatum, we identified and confirmed that cylindromatosis‐associated deubiquitinase (Cyld), a deubiquitinase specific for Lys63‐linked polyubiquitin chains, was up‐ and down‐regulated in Shank3 TG and KO striatal synapses, respectively. Consistently, we found that the synaptic levels of Lys63‐linked polyubiquitin chains were down‐ and up‐regulated in the Shank3 TG and KO striata, respectively. Furthermore, by isolating and analyzing the synaptic Cyld complex, we generated a Cyld interactome consisting of 103 proteins, which may include Cyld substrates. Bioinformatic analyses suggested associations of the Cyld interactome with a few brain disorders and synaptic functions. Taken together, these results suggest that Shank3 regulates the synaptic abundance of Cyld in the mouse striatum and, thereby, potentially modulates the Lys63‐linked polyubiquitination of striatal synaptic proteins
An Enzyme-Inspired Formulation of the Electrolyte for Stable and Efficient Vanadium Redox Flow Battery at High Temperatures
No full textHistidine, inspired by vanadium bromoperoxidase enzyme, has been applied as a homogeneous electrocatalyst to the positive electrolyte of vanadium redox flow battery (VRFB) to improve the performance and stability of VRFB at elevated temperatures. The histidine-containing electrolyte is found to significantly improve the performance of VRFB in terms of thermal stability estimated by the remaining amount of VO2+ in the electrolyte (61 vs 43% of a pristine one), energy efficiency at a high current density of 150 mA cm–2 (78.7 vs 71.2%), and capacity retention (73.2 vs 27.7%) at 60 °C. The mechanism of the catalytic functions of histidine with the chemical species in the electrolyte has been investigated for the first time by multinuclear NMR spectroscopy and first-principles calculations. The analyzed data reveal that histidine improves the kinetics of both charge and discharge reactions through different affinity toward the reactants and products as well as suppresses the precipitation of VO2+ by impeding the polymerization of vanadium ions. These findings are in good agreement with the improved chemical and electrochemical performance of the histidine-containing VRFB. Our results show a new type of chemical/electrochemical mechanism in the improved redox flow battery performance that may be essential in a new research arena for better performance of electrochemical system
