In this paper, a Efficient method for the mixed image separation is presented using independent component analysis and the new fast expectation-maximization(EM) algorithm. In general, the independent component analysis (ICA) is one of the widely used statistical signal processing scheme in various applications. However, it has been known that ICA does not establish good performance in source separation by itself. So, Innovation process which is one of the methods that were employed in image separation using ICA, which produces improved the mixed image separation. Unfortunately, the innovation process needs long processing time compared with ICA or EM. Thus, in order to overcome this limitation, we proposed new method which combined ICA with the New fast EM algorithm instead of using the innovation process. Proposed method improves the performance and reduces the total processing time for the Image separation. We compared our proposed method with ICA combined with innovation process. The experimental results show the effectiveness of the proposed method by applying it to image separation problems.

Innovation, especially business process innovation, has evolved into a core focus area for all successful organizations. To ensure long-tenn survival, an enterprise must place innovation at the top of daily business operations to drive desired revenue stability and growth. Business Process Innovation is a key success factor for the next generation enterprise. Companies need to nurture an environment that encourages and enables process innovation. Business Process Management (BPM) must become the focal point of innovation initiatives. But the most BPM solutions are for large company. The cost is too high to build for small and medium sized company. We need the light and easy BPM solution for small and medium sized company. In this paper, we introduce the SESS which is BPM solution for small and medium sized company.

This paper examines the effect of innovation strategy and R&D organization on the innovation performances in the Korean small and medium sized enterprises(SMEs). For the SMEs with limited resources and capabilities, the one of key strategic issues is to allocate innovation resources to the exploitation of existing technological capabilities and/or the exploration of new technological capabilities. Based upon survey data from 769 SMEs, this study investigated relationships among exploitation and exploration strategies, the existence of R&D organization, and innovation performance. Exploration is positively related to product and process innovation performances across the industrial sectors. However, exploitation is positively related only to the process innovation performance in the traditional manufacturing sectors. The existence of R&D organizations has positive effects on the product innovation performance and not on the process innovation performance. Finally, it discusses the managerial implications, the limitations of this study and the future research directions.

This paper investigates how small-medium firms deploy organizational culture, job stability and environmental uncertainty for technological innovation(product and process innovation). This paper suggests that organizational culture has significant effects on technological innovation, that job stability and environmental uncertainty moderate relationship between organizational culture and technological innovation. To test the hypotheses, data were collected from small-medium firms. The survey data of 258 firms were collected and integrated as the empirical base for testing the hypotheses. Major results are as follows: Firstly, when organizational culture as well as control variables are considered, organizational culture had significant and positive effects on product innovation. This result implies that organizational culture is an important means by which small-medium firms can promote innovation. Secondly, the interaction between organizational culture and job stability had a positive and significant effects on product innovation. Thirdly, the interaction between organizational culture and environmental uncertainty had a positive and significant effects on product innovation and process innovation.

This study empirically analyzed the impact of technological innovation on corporate performance and the moderating effect of technology commercialization capability in this relationship. The purpose was to identify the impact of technological innovation activities, divided into process innovation and product innovation, on financial and non-financial performance, and to clarify the role of technology commercialization capability. An online survey was conducted with 300 companies from April to May 2024, and the results were analyzed using SPSS 29.0 and Process macro. The results showed that technological innovation had a positive effect on both non-financial and financial performance of the company. In addition, it was confirmed that the higher the technology commercialization capability, the stronger the impact of technological innovation on non-financial performance. However, technology commercialization capability did not significantly moderate the relationship between technological innovation and financial performance. This study empirically demonstrated the importance of technology commercialization capability in the relationship between technological innovation and corporate performance, and is expected to provide useful implications for establishing corporate technology innovation strategies and developing policies in the future.

Crosslinked agar-g-poly(acrylic acid) (x-agar-g-PAA) super absorbent with a water absorbency ($Q_{H2O}$) of approximately 660 g/g was synthesized by the copolymerization of agar with an acrylic acid monomer. KPS and MBA were used as the initiator and crosslinker, respectively. Grafting was performed in air. Infrared spectroscopy was used to identify the product of copolymerization. The optimum conditions to synthesize the x-agar-g-PAA superabsorbent were 0.1 g of agar, 0.1 g of the KPS initiator, for 15 min; 50% AA monomer, 0.005 g of the MBA crosslinker, for a propagation time of 5 min; and 1 M NaOH for 15 min to allow for saponification. The reaction temperature was $80{^\circ}C$.

This paper articulates the STI strategy development principles and methodologies that have been elaborated through iterative processes of STI strategy development cases for the past ten years. The consultation cases include poverty traps in Nepal and Laos, African health challenges in Nigeria and Tanzania, and ASEAN global challenges in Indonesian Water, Vietnamese Green Energy, and Filipino Food, in partnership with some multilateral agencies.The iterative elaboration process has continued with consultation activities on Thailand and on Cambodia, Laos and Myanmar in planning partnership with Thailand. The principles were originally conceptualized from the benchmarking process of the Korean STI development experience. They were further incorporated as methodologies with which relevant planning bodies are guided to address individual and regional challenges through science, technology and innovation strategies. The methodologies are strong in providing plausible holistic perspective scenarios by which various stakeholders can be engaged in the planning and implementation process. But it is heuristic in nature and can be learned only through on-the-job training process. This is the structural limitation for scaling up.

This study investigates consumers' perceptions when customers participate in the process of innovating new products or new services essential to companies in the era of the 4th industrial revolution. Specifically, this study investigates how consumers' product evaluation varies depending on two types of innovation for a company's new product development (technology-based innovation and market-based innovation) and two customer roles (as information providers and as co-developers) participated in the development process. The research questions are as follows: As technology-based innovation and market-based innovation are different types of innovations, will consumers' product evaluation vary depending on these different types of innovation? If customers participate in the development process of a new product reflecting each innovation, how will the information that the customer participated be perceived by other consumers? In addition, this customer participation method can serve as an information provider and a co-developer, and will consumers' evaluation of new products vary depending on this role? As a result of verifying the hypothesis using an experimental method, it shows that consumers' product evaluation differs significantly depending on the role of customers who participated in the process of developing new product development process. In other words, the results indicate that the case where customers participated as market information providers in the process of developing new products is more favorable to the new product evaluation than the case where they participated as co-developers of the new products. In addition, there is an interaction effect between the type of product innovation and the role of customer participation. To be specific, when a product reflecting technological innovation is released, there is no difference in consumers' product evaluation according to the roles of two different customer participations. However, when a market-based innovation product is released, product evaluation is more favorably perceived when customers participated as information providers than they were involved in the new product development process as co-developers. This study is of theoretical significance in that it distinguishes each type of innovation and verified how other consumers' perceptions vary depending on their role when customers participate in the innovation process. Finally, limitations and future study directions are suggested along with practical implications.
