This study suggests a Causal Loop Diagram(CLD) of causality mechanism which are integrating matters of localization, networking, embeddedness & institutional thickness and collective learning. These five factors(localization, networking, embeddedness & institutional thickness, collective learning, innovative synergy) have been studied and proofed Also this study suggest a model of industry cluster based on holistic and global system thinking rather than local and linear thinking.

Cellulosomes in Clostridium cellulovorans are assembled by the interaction between the repeated cohesin domains of a scaffolding protein (CbpA) and the dockerin domain of enzyme components. In this study, we determined the synergistic effects on cellulosic and hemicellulosic substrates by three different recombinant mini-cellulosomes containing either endoglucanase EngB or endoxylanase XynA bound to mini-CbpA with one cohesin domain (mini-CbpAl), two cohesins (mini-CbpA12), or four cohesins (mini-CbpAl234). The assembly of EngB or XynA with mini-CbpA increased the activity against carboxymethyl cellulose, acid-swollen cellulose, Avicel, xylan, and com fiber 1.1-1.8-fold compared with that for the corresponding enzyme alone. A most distinct improvement was shown with com fiber, a natural substrate containing xylan, arabinan, and cellulose. However, there was little difference in activity between the three different mini-cellulosomes when the cellulosomal enzyme concentration was held constant regardless of the copy number of cohesins in the cellulosome. A synergistic effect was observed when the enzyme concentration was increased to be proportional to the number of cohesins in the mini-cellulosome. The highest degree of synergy was observed with mini-CbpAl234 (1.8-fold) and then mini-CbpAl2 (1.3-fold), and the lowest synergy was observed with mini-CbpAl (1.2-fold) when Avicel was used as the substrate. As the copy number of cohesin was increased, there was more synergy. These results indicate that the clustering effect (physical enzyme proximity) of the enzyme within the mini-cellulosome is one of the important factors for efficient degradation of plant cell walls.

Long Short-Term Memory (LSTM) combined with attention mechanism is extensively used to generate semantic sentences of images in image captioning models. However, features of salient regions and spatial information are not utilized sufficiently in most related works. Meanwhile, the LSTM also suffers from the problem of underutilized information in a single time step. In the paper, two innovative approaches are proposed to solve these problems. First, the Synergy-Gated Attention (SGA) method is proposed, which can process the spatial features and the salient region features of given images simultaneously. SGA establishes a gated mechanism through the global features to guide the interaction of information between these two features. Then, the Recurrent Fusion LSTM (RF-LSTM) mechanism is proposed, which can predict the next hidden vectors in one time step and improve linguistic coherence by fusing future information. Experimental results on the benchmark dataset of MSCOCO show that compared with the state-of-the-art methods, the proposed method can improve the performance of image captioning model, and achieve competitive performance on multiple evaluation indicators.

The article reflects short-term perspectives on the use of information and communication technologies in the training of teachers for higher education. Education is characterized by conservatism, so aspects of systematic development of the industry are relevant to this cluster of social activity. Therefore, forecasting the introduction of innovative elements of ICT training is in demand for the educational environment. Forecasting educational trends are most relevant exactly in the issues of training future teachers of higher education because these specialists are actually the first to implement the acquired professional skills in pedagogical activities. The article aims to consider the existing potential of ICT-based learning, its implementation in the coming years, and promising innovative educational elements that may become relevant for the educational space in the future. The tasks of scientific exploration are to show the optimal formats of synergy between traditional and innovative models of learning. Based on already existing experience, extrapolation of conditions of educational process organization with modeling realities of using information and communication technologies in various learning dimensions should be carried out. Educational trends for the next 3 years are a rather tentative forecast because, as demonstrated by the events associated with the COVID-19 pandemic, the socio-cultural space is very changeable. Consequently, the dynamism of the educational environment dictates the need for a value-based awareness of the information society and the practical use of technological advances. Thus, information and communication technologies are a manifestation of innovative educational strategies of today and become an important component along with traditional aspects of educational process organization. Future higher education teachers should develop a training strategy taking into account the expediency of the ICT component.

소공인클러스터의 지원정책은 소공인클러스터의 지역적 특성을 반영해야 하지만, 유관기업의 통상적인 정보 수집을 기반으로 비슷한 정책만 내놓고 있다. 소공인클러스터의 지역적 특성이 파악이 안 되므로 지원정책에 반영이 되지 않고 있는 실정이다. 이에 본 연구는 소공인클러스터의 특성을 클러스터의 특징인 국지화, 네트워킹/착근성, 혁신시너지/집단학습의 형성요소로 분석하였으며, 분석된 형성요소를 기반으로 발달단계를 적용해 보았다. 같은 업종이어도 지역적 특성이 다를 수 있으므로, 서울시 의류봉제업의 대표적인 클러스터인 창신지역과 장위지역의 소공인클러스터를 지역적 특성과 발달단계로 비교 연구하였다. 의류봉제 소공인클러스터의 특성 분석 결과, 국지화에서 동종업체 집적은 창신지역이 장위지역보다 높게 나타났으며, 네트워킹/착근성에서 두 지역 모두 잘 형성되어 있었다. 하지만 혁신시너지/집단학습의 협업에서 창신지역은 디자이너 중심으로 장위지역은 소공인 중심으로 이루어져 있고, 박람회 및 세미나 참여와 샘플 및 제작에 있어 창신지역은 적극적인 반면 장위지역은 소극적으로 나타났다. 두 형성요소로 살펴본 결과, 두 지역의 소공인클러스터의 발달단계는 창신 의류봉제 소공인클러스터의 경우 산업지구를 넘어 혁신지구로 진행되고 있고, 장위 의류봉제 소공인클러스터는 산업지구에 머물러 있는 것으로 분석된다. 창신과 장위 의류봉제 소공인클러스터는 지속적인 성장을 위해서는 두 지역의 특성과 발달단계를 반영한 정부의 지원정책이 필요하다고 제언한다.

In this paper, we examined the difference of the effects of buying factors in two consumer segments divided by the innovative behavior for digital convergence products, and developed relevant managerial implications. As the digital convergence product could be understood as a innovative bundling product, the buying factors of the digital convergence products were clustered in 3 groups : common innovation-bundling factors, innovation factors and bundling factors. Tests for the difference of regression coefficients of the purchasing factors in the two markets show that (1) the early market is affected by both of the common innovation-bundling factors and the innovation factors, while the mainstream market is affected by all of the common innovation-bundling factors. the innovation factors and the bundling factors, (2) the early market is more affected by the technical benefit, while the mainstream market is more affected by the pragmatic benefit, and (3) both of the two markets are affected by the compatibility and the message communicability. The relevant managerial implications for the successive diffusion of the digital convergence products can include (1) in the entire period of the diffusion. enhancing the compatibility between consumer and product concept, performing constant and differentiated marketing communication activities, (2) in the early market of the diffusion, introducing unique innovative product which provides obvious and differential synergy through the convergence, appealing to the technical benefit, and (3) in the mainstream market of the diffusion, improving the qualities and features of individual products for the digital convergence product, appealing to the pragmatic benefit, reducing the complexity of product.

본 연구는 일과 삶의 균형(WLB:Work-Life Balance)의 한 영역인 일 성장 균형(WGB: Work-Growth Balance)이 대인 조화와 창의적 노력 및 조직 내 혁신 행동을 향상시키는지 여부, 그리고 대인 조화와 창의적 노력이 일 성장 균형(WGB)과 혁신 행동 간의 관계에 간접 효과가 있는지 여부를 알아보기 위해 수행되었다. 본 연구의 가설 검증을 위해서는 Hayes(2013)의 PROCESS Macro를 활용하였다. 분석결과 혁신행동에 영향을 주는 것은 일 성장 균형(WGB)과 대인조화 그리고 창의적 노력으로 나타났고 대인조화에 영향을 주는 변수 역시 일 성장 균형(WGB)으로 나타났다. 또한 창의적 노력에 영향을 미치는 변수는 일 성장 균형(WGB)과 대인조화였다. WGB와 혁신행동 사이의 관계에서 대인조화와 창의적 노력의 간접 효과 역시 확인되었다. 더불어 PROCESS Macro 분석을 통하여 매개변수 간의 효과의 크기를 알아보았다. 이를 통해 일 성장 균형(WGB)이 대인조화, 창의적 행동 및 혁신행동 간에는 시너지 관계가 존재함을 알 수 있었다. 향후 다양한 다른 산업 간의 일 성장 균형(WGB)에 대한 연구와 일 성장 균형(WGB)과 혁신행동에 이르는 좀 더 다양한 매개변수에 대한 연구 그리고 일 가정 균형, 일 여가 균형에 대한 추가 연구도 기대된다.
