Structural deterioration arises due to aging, environmental effects, deficiencies during design and construction phase, and overloading. Experimental and numerical investigations are carried out in this study to evaluate the performance of control and flexural deficient reinforced concrete (RC) beams under monotonic loading. Three levels of flexural deficiency are considered in this study. After confirming load carrying capacities of control and flexural deficient beams, the flexural deficient RC beams are strengthened with carbon fibre reinforced polymer (CFRP) fabric. CFRP strengthened RC beams are tested under monotonic loading and compared with the performance of control specimen. Further, non-linear finite element analyses are also carried out to evaluate the flexural performance of control, deficient and CFRP strengthened flexural deficient RC beams. There is good correlation between results of experimental and numerical investigations. Numerical approach presented in this study can be adopted for assessing the adequacy of CFRP retrofit measure.

The spherical steel bearings (SSBs) has been gradually replaced traditional rubber bearings and extensively applied to high-speed railway (HSR) bridges in China, due to their durability and serviceability. Nevertheless, SSB is generally simplified to the ordinary constraints in the finite element model, which cannot reflect its detailed mechanical characteristics, especially its seismic performance. To provide a more precisely simulation, an innovative and simplified finite element simulation method is proposed and the combined element group is developed in ANSYS. The primary parameters were determined by means of the performance test of SSB. The finite element model of SSB applied to a single-span HSR simply supported girder bridge was established through the proposed method. The seismic performance of the SSB was further investigated. A shake table test was conducted to evaluate the accuracy of the proposed simulation method. It is found that the numerical results could have a good agreement with the experiment, namely, the proposed method is feasible and efficient.

Since service innovation is considered as a new way to gain an advantage in a highly competitive environment, it is imperative for companies to align their service innovation strategy with their business strategy in order to achieve better firm performance. Accordingly, a critical challenge facing firms is how to effectively organize and manage a well-planned service innovation strategy in accordance with the direction of their business strategy. Firms with a good fit between business strategy (i.e., cost leadership, innovative differentiation, and marketing differentiation strategies) and service innovation strategy (service creation-focused, service delivery-focused, and client interface-focused strategies) are expected to have better firm performance than those without such a fit. Based on empirical data from 209 service firms in South Korea, this study aims first to investigate whether a certain service innovation strategy is more effective than others within a particular business strategy. We then examine whether their effective alignment positively affects firm performance. The empirical evidence indicates that the alignment of service innovation strategy with business strategy significantly influences firm performance. The adoption of service innovation strategy was found to have positive effects on firm performance with innovative differentiation and marketing differentiation strategies and negative effects with cost leadership strategy. Lastly, we discuss our study's implications for further research and practice.

This study is to confirm the core factors of innovative capabilities and technological entrepreneurship affecting the performance of technology management and business management of small and medium-sized enterprises (SMEs). Through the consideration about the complex natures of technological innovation affecting by multidimensional factors, this study designs the research model that innovative capabilities, the performances of technology and business management are arranged in accordance with the innovation process; input-output-outcome. To meet this research purpose, the hypothesis are set up based on the previous research studies and the research samples are selected from members of the Innovative Business (INNO-BIZ) Association, located in Seoul and Geyonggi province. As a result of regression analysis to the responses gathered from 360 firms, the performance of business management is influenced positively by the technology superiority, market growth and business profitability which are the dominant factors of performance of technology management. In addition, three sub-variables of innovative capabilities such as R&D, strategic planning and learning capability, have positive effects on both the managerial performances. Innovativeness and progressiveness of technological entrepreneurship affect both the performances positively. Moreover, the co-relation between technological entrepreneurship of an innovation leader and innovative capabilities of organizational members are identified. Lastly, technological entrepreneurship has the mediating effect on the path of leading innovative capabilities to the managerial performances. In conclusion, the research results imply that technological innovation-type firms should periodically evaluate the performance of technology management which are the output of technological innovations and the reinvestment for ultimate business success. And improving and developing innovative capabilities and technological entrepreneurship is required to continuously and consistently investing and supporting resources on technological innovations at the firm-and government-level. It is considered that these are the crucial methods for securing the technologically competitive advantage of SMEs with less resources and narrow innovation range.

New and innovative technologies for utilizing daylight in buildings have been developed for saving energies and improving visual environments. This study describes the most up-to date information available about the application and evaluation of advanced daylighting systems to enhance daylighting in non-residential buildings from IEA's Task 21. IEA's Task 21 consists on 4 subtasks such as "Performance Evaluation of Daylighting Systems(subtask A)", "Daylighting Responsive Controls(subtask B)", "Daylighting Design Tools(subtask C)" and "Case Studies(subtask D)". For the study, the configurations and characteristics of IEA's advanced daylighting systems are comparatively analyzed. As results, innovative daylighting systems are designed to redirect sunlight or skylight to areas which it is required without glare. These systems use optical devices that initiate reflection or refraction of sunlight and skylight. And they can be designed to actively track the sun or passively control the direction of sunlight and skylight. The comprehensive overview of innovative daylighting systems presented in this study helps designer to understand the advantages of daylighting in building and choose a suitable system for building in the earliest stage of the design process.

The purpose of this study is to suggest directions for enhancing competitiveness of corporate management by examining how individual creativity and organizational members' value innovation culture perception affect innovation behavior and knowledge sharing, and how innovation behavior and knowledge sharing affect organizational innovation performance and management outcomes In order to achieve these research objectives, the measurement variables of each variable were extracted through previous research and 423 valid samples were analyzed using SPSS 22.0 statistical package program and LISREL 9.1 to verify a hypothesis. As a result of this study, it was found that the creative thinking skills of the individual creativity, the meaningful tasks of the value innovation culture recognition, and the risk - taking culture have a significant influence on the innovation behavior. Only the meaningful tasks of organizational members' value innovation culture perception affect knowledge sharing. Innovation behavior has a significant effect on knowledge sharing and innovation performance, but not on business outcome. In addition, knowledge sharing has no significant effect on innovation performance but has a significant effect on business performance. Finally, we confirmed that innovation performance has a significant effect on management outcome.

Despite the tremendous efforts to boost them, domestic SMEs lack competitive power and it intensifies bipolarization between the conglomerates and SMEs. Furthermore, degree of industry-academy collaboration still falls far behind of that of developed countries even with government' s various policies and continuous increase in investment to strengthen the SMEs' technology innovation capability. Although many internal factors are suggested to affect technological performance, focus of existing studies has been restricted to immediate impact of industry-academy collaboration on technology innovation and it is not known how internal factors are related. This research conducts empirical analysis on the impact of industry-academy collaborations and absorptive capacity on technological performance in Korean SMEs. Sample frame is SMEs with more than five employees located in the nation wide industrial complex and 1,077 questionnaires are collected with the help of Korea Industrial Complex Corporations. 940 sample data excluding those with insufficient response are used in analysis. Multiple regression analysis revealed that the industry-academy collaborations and innovative HRM system, on important dimension of absorptive capacity, are positively correlated to technological performance. Furthermore, there exists a positive interaction effect between industry-academy collaborations and innovative HRM system. These findings make contributions to the formation of SME innovation policy and management. When funding industry-academy collaborations, government should consider SMEs' internal effort for innovation, that is, the possession of innovative HRM system, as well as firm's technology capability. Also, as technological performance cannot be achieved simply with R&D investment, both quantitative and qualitative assessment of SMEs' technological capability should be done to evaluate the candidate SMEs. As for management, it is important for SMEs with limited internal resources and capabilities to fully employ external resources to achieve higher technological performance. The development of innovative HRM system will be particularly helpful not only for internal R&D, but also for adoption of technology and knowledge from outside.
