Purpose: This study explores how supplier and customer integration impact a firm's disruption absorption capability, with a focus on IT alignment moderation. Methods: We conducted surveys with 296 Chinese manufacturers and utilized hierarchical regression for analysis. Results: : Our results reveal a positive correlation between supplier/customer integration and disruption absorption capability. Additionally, positive IT alignment bolsters the relationship between supplier integration and disruption absorption capability, while it doesn't affect the link between customer integration and disruption absorption capability. Conclusion: These findings underscore the significance of integration and IT alignment for enhancing a firm's disruption absorption capability, providing crucial insights for supply chain management practitioners.

The nonuniformity of energy absorption capability of ZnO varistor is systematically discussed in this paper. The nonuniformity of electrical characteristics and microstructure leads to decrease the energy absorption capability of ZnO varistor. The energy absorption capabilities were measured under different current waves, the experimental results stated that they have highly scattered phenomena. The influences of varistor surface area and nonuniformity of electrical characteristics to the energy absorption capability and the nonuniformity of commercial ZnO varistors were analyzed. There is a high nonuniformity existing in the energy absorption capability of commercial ZnO varistors.

The purpose of this research was to test the effects of entrepreneurship and technological innovation capability on new product performance in SMEs and the moderating role of absorption capability. For this study, Research data were collected through questionnaire instruments from the sample of 374 employees in 18 SMEs of metropolitan area. The 336 sample was selected and analyzed by hierarchical regression technique. The results showed that entrepreneurship and technological innovation capability had a positive effect on new product performance. And also found out absorption capability had the moderate roles between all the three factors of technological innovation capability factors and new product performance, but not between all the three factors of entrepreneurship and new product performance. With the research results, the implications for technical management of SMEs were discussed, and the directions for future research were suggested.

This study was carried out to investigate the relation between surface roughness and heat absorption capability of materials for solar collector. For this purpose, 3 kinds of materials (copper, aluminum, iron), 5 kinds of surface roughness (scrubber, alumina sand #80, #200, #400, glass bead) and 2 kinds of surface treatment (black chrome plating, copper black coating) were used for finding optimal conditions to apply solar collector. As the results, it was confirmed that the optimal relations between surface roughness and surface treatment as well as optimal materials were necessary. Further, heat absorption capability was showed good results in cases of copper materials, glass bead and black chrome plating.

This study aims at examining the relationship among entrepreneurial orientation, absorption capability, alliance capability and cooperation performance in technological cooperation between SMEs and government-funded R&D Institutes. For empirical analysis, the study conducted a survey on total 2,895 SMEs participating in the technological cooperation programs operated by government-funded R&D Institutes, and collected 332 survey responses. Data were analysed using a structural equation model. Empirical results show that entrepreneurial orientation, absorption capability, and alliance capability influenced the performance of technological cooperation. In addition, alliance capability has a significant effect on absorptive capacity. In order for the technology cooperation between SMEs and government-funded research institutes being successful, efforts are needed to secure companies' entrepreneurial orientation, absorption capability and alliance capability that has the capabilities that SMEs needs for technological cooperation.

The sound absorption materials With polyester (PET) were prepared for automobile. They consist of 3 layers with different size of PET fiber (3 and 15 deniers) in order to optimize the characteristic of sound absorption, and with various densities (895~1790 g/$cm^2$) by controlling the weight of PET of each layer. They were also compared with the commercial sound absorption materials made of glass wool. It was shown that the new PET had better absorption capability in both high and low frequency regions than that of the commercial material. It was revealed also that the density and the thickness of PET played an important role to determine the capability of sound absorption. The NRC (noise reduction coefficient) was increased by 22-39% with optimized PET sound absorption material. It should be noted that the PET can substitute the glass wool, a commercial sound absorption material, in view of environment and as well as recycle capability of sound absorption.

ZnO varistors have been widely used to protect power system and electronic system against overvoltages based on their excellent nonlinearity. In order to increase their protection capability, ZnO varistors are chosen by several electrical parameters according to their applications, namely 1mA DC voltage, 1eakage currents, impulse residual voltages, withstanding capability to impulse surge, and energy absorption capability. But these Parameters have scattering properties due to the nonuniformity of electrical characteristics. In this study, the effect of the microstructrual nonuniformity on the surge absorption capability of ZnO varistors.

Elastostatic compression tests were carried out on amorphous alloys to evaluate their energy absorption capability during homogeneous deformation at room temperature. Experiments demonstrated that a compressive stress below the global yield imposed on amorphous alloys for extended periods causes homogeneous plastic strain associated with the irreversible structural disordering. During the disordering process, free volume was created, dissipating the externally applied strain energy and the rate of creation was found to converge to a saturated value. We evaluated the capability of energy absorption of amorphous alloys during homogeneous deformation using recent theories on the evolution of the structural state.

In this paper, a distributed amplifier is designed using distributed network synthesis that provides the optimum absorption capability of a capacitance. Transfer functions of filters, which consist of the amplifier, are synthesized by a low-pass Chebyshev approximation. Capacitances that a filter network can absorb are calculated as a function of its minimum insertion loss(MIL) and ripple. Active devices in a distributed amplifier are modeled as equivalent circuits by using their S-parameters, and their equivalent capacitances are absorbed into filter structures by properly adjusting the MIL and ripple of a transfer function. As an application example, a distributed amplifier with the gain of about 12.5dB is designed that operates over the frequency range between 0.1 and 7.5GHz. Experimental results prove that distributed network synthesis, which considers capacitance absorption capability, is useful to the design of distributed amplifiers.

The changes in sound absorption capability and air permeability of Malas wood after high temperature heat treatment were investigated. The average air permeability of Malas in longitudinal direction after heated under the temperature of $190^{\circ}C$ during 3 hours was about 23.48 darcys and that of control was about 3.11 darcys. The noise reduction coefficients of Malas specimens were 17% for treatment and 10% for control. The means of sound absorption coefficient of specimens in the frequency range of 50~6,400 Hz were 42% for treatment and 17% for control, respectively.
