This study aims to analyze the effect of absorptive capacity on technology collaboration performance and the moderating effect of innovation intermediaries. We set absorptive capacity (potential, realized) as independent variables and technology collaboration performance (relative technology level, development period, cost savings, new product development, collaboration satisfaction) as dependent variables, with innovation intermediaries as a moderating variable. We conducted a survey of 145 ICT companies that experienced technology collaboration and analyzed the data using 101 valid responses. The results show that potential absorptive capacity has a significant effect on new product development and collaboration satisfaction, while realized absorptive capacity has a significant effect on relative technology level, cost savings, and new product development. Furthermore, innovation intermediaries have a moderating effect between realized absorptive capacity and new product development. The contribution of this study to academia and industry is that it highlights absorptive capacity as a key factor influencing technology collaboration performance. The limitations of this study include the lack of accurate measurement of absorptive capacity and innovation intermediaries, as well as a lack of control over external factors. These limitations should be addressed through more in-depth research by systematically defining and measuring them in future follow-up studies.

New aminothiazolyl cephalosporins with alkoxyiminomethyl(2-aminothiazol-4-yl)acetyl substituents at 7-position of cephems were synthesized starting from (2-aminothiazol-4-yl)acetate via one carbon homologation followed by acylation with 7-aminoceph-3-em-4-carboxylic acid derivatives. These new aminothiazolyl cephalosporins exhibit promising in vitro activities against various strains including Gram positive bacteria.

The 1,3-bis(4-aminoaryl)squaraines showed color, change behavior, they were found to undergo reduction with sodium borohydride in solution to give colorless leuco compounds, which oxidized readily in air back to the colored squaraine dye. We have shown that initial observations indicated that the derivatives synthesized gave new donor-acceptor chromophores. It is also interesting to note than the oxidation of the leuco squaraines did initially produce a species absorbing about 630-680 wavelengths. The 1,3-squaraines have found many uses as near-infrared absorbers, laser dyes and photoconductive materials. Furthermore their color-change redox behavior has potential in the area of peroxidase-based bioassaysas oxidation sensitive indicator systems were investigated.

In most resource reservation strategies, which give higher priorities to handoff calls over new calls, new calls are often blocked even though there is plenty of available reserved resource. This causes inefficient resource utilization, especially when there are not so many handoff attempts. In this paper, we propose a new reservationstrategy called soft reservation in which new calls can be allocated to the reserved resource while maintaining the QoS of handoff acceptable. Using an M/M/c/c queuing model, we can see that the proposed strategy provides better performance than the conventional reservation strategy in terms of blocking probability of new call and dropping probability of handoff calls.

In this study, a new type of Aliquat 336/PVC membrane has been made for extraction experiments. This new membrane is capable of holding more Aliquat 336 than previously developed extraction membranes, hence overcoming a major problem that has confronted many researchers for a long time. The new membrane has been used try investigate the rate of extraction fur the Cd(II) ion in 2.0 M HCI solution and the effect of membrane thickness on the rate of extraction. The experimental results have shown this new membrane has a promising future in relevant industrial applications. A new method is also used in this study to qualitatively identify the oily substance on the surface of membrane after the extraction experiment was completed. This oily substance has been found to be Aliquat 336.

A new computationally efficient algorithm-based propagator method for two-dimensional (2-D) direction-of-arrival (DOA) estimation is proposed, which uses two parallel uniform linear arrays. The algorithm takes advantage of the special structure of the array which enables 2-D DOA estimation without pair matching. Simulation results show that the proposed algorithm achieves very accurate estimation at a computational cost 4 dB lower than that of standard methods.

According to the empirical study, the research model has been verified about the introduction of new ubiquitous technology into the Customs Information System. The research model is meaningful in deducing policy for accepting the new ubiquitous technology into the Customs Information System. The organization style is not yet positively accomplished, because of insufficient recognition about the new ubiquitous instrument. The other side the individual style, environmental style and working characteristics are contribute to accept the new ubiquitous environment, because of sufficient of education, usage and recognizing the usefulness of the portal information. It is established the Customs Information System with new ubiquitous technology such as RFID, DM, UCR etc.. for the usefulness and convenience.

This study analyzed the performance of new construction technology in construction site. The main results are as follows. First, 83.6% of the new technologies developed by SMEs(joint development by large enterprises) account for the majority. Second, new construction technology is mainly applied to construction and civil engineering, but it is mainly applied to four major types of work(waterproofing, soil and foundation, reinforced concrete, bridge). Third, the number of on-site applications with a construction value of less than 500 million accounted for 89.5% of the total, which indicates that new construction techniques are mainly applied to small-scale construction.

This study proposes a framework for an evaluation and selection of a venture firm with promising new technology in optical electronics industry to nurture that firm. The framework is intended to help practitioners to evaluate accurately and objectively new technologies. In addition, this study tests the usability and effectiveness of this framework with an actual certain case. More specifically, this study, first proposes that the framework for new technology evaluation is composed of financial perspective, market perspective, internal business perspective, and R&D and growing perspective. They are on the four perspectives of BSC(Balanced Score Card). Each perspective contains specific items. In addition, this study uses AHP(Analytic Hierarchy Process) to assess the comparative importance among the four perspectives and their specific items. Secondly, based on the results of AHP, the usability and effectiveness of the framework suggested in this study have been tested with a real case evaluating and selecting a promising venture firm. The results of the study have the following implications: this study has developed the framework for new technology evaluation which assists practitioners. Our framework offers the four perspectives and their specific items with their respective comparative importance. Furthermore, this study has verified that the proposed framework can be applicable in real situation with more accurate results.
