This study examines the effect of social capital formed on B to B inter - firm transactions on firm's performance through a research model developed around the mediating effect of knowledge absorption capacity. In other words, we examined how each level of social capital affects firm performance. by examining the dimensions of social capital that are not presented in previous studies, we have identified how each element of social capital affects corporate performance. in addition, the effects of knowledge absorption on firm performance are analyzed and presented in various ways. The results of the study are summarized as follows. First, social capital is divided into three dimensions. In other words, the relationship between structural elements, relational dimensions, and cognitive dimensions was verified. First, the structural dimension influenced the relational dimension, and the relational dimension had a positive effect on the cognitive dimension. this is meaningful in that it solved what is pointed out as a limit in previous studies. this is meaningful in that it verified what was pointed out as a limit in previous studies. secondly, the structural dimension influenced the cognitive dimension. Second, each component of social capital has a positive impact on knowledge absorption capacity. Finally, it was found that knowledge absorption capacity had a positive effect on the corporate culture, and it was confirmed that knowledge absorption capacity was important. the extent to which social capital is absorbed in BtoB transactions means that the performance of the two companies can be quite different.

We compared electromagnetic(EM) wave absorption properties between Alnico magnet (A) and (B) with different magnetic properties. Also, we investigated the effect of carbon, thickness of absorbers, and Alnico contents on EM wave absorption, and clarified the relation between Alnico content and central frequency.

In this paper a new theory is presented to treat the problem of stimulated absorption and emission of photons between energy levels from the standpoint of discrete quantum jumps. In order to implement the theory a scheme to avoid the quantum Zeno effect is proposed. Numerical simulations are performed to demonstrate that this approach does not contradict the principles of the standard wave mechanics. It is shown that with this approach one can obtain photon observation statistics as well.

In this study, As a previous stage to manufacture disposable tent for military camouflage, we examine possibility of inorganic material absorption on PET surface. In order to, we created unevenness by sputtering process on PET surface and made absorption with Zirconium (ZIA) that has nano particles. and we went on study to its effect.

The effects of total saponin, triol and diol saponin, and prosapogenin of ginseng on the absorption of cholesterol and the component of serum lipids was observed as a function of time using isotopic method. The following results were obtained. 1) Labelled cholesterol absorption was observed to be enhanced after adminstrations of total saponin, triol saponin, and. prosapogenin of ginseng to rat (Sprague Dawley). 2) Decreases in the amount of serum lipid were observed after administration of total saponin and prosapogenin of ginseng.

The purpose of this paper was to study the effect of surfactants on the absorption and the bioavailability of ascorbic acid in the small intestine of rats and rabbits absorption of ascorbic acid in small intestine of rats was increased with tween 80 and span 80.The blood level of ascorbic acid in rabbits was elevated by combined with low concentration of surfactants but high concentration of surfactants. The bioavailability of ascorbic acid was increased by simultaneous administration of surfactants.

Comparison for various empirical models of normal incident absorption was made, along with experiments. Comparative result indicates that Voronina model which is function of fiber diameter and porosity is more suitable than the other models. An investigation for correlation between normal and random incident absorption was carried out by experiment and analysis. It appears that at the low frequencies, the random incident absorption is higher than the normal one, whileas at the high frequencies, the random incident absorption is decreased due to the effect of grazing incident components.

An oil layer fuel absorption /desorption modeling was developed. Multi-component fuel model has showed more reasonable condition than single component model. Henry's constant which is related to solubility is the most important variable in the oil layer absorption/desorption mechanism. The oil segments close to the top of the cylinder liner have more significant contribution to the fuel absorption and desorption process than other oil segments. At the warmed-up condition, the effect of the engine speed on the precent fuel absorbed/desorbed is minimal. But at low il film temperature, percent of fuel abosrbed/desorbed is decreased with increasing the engine speed because of low value of molecular diffusion coefficient of fuel. The amount of fuel trapped in the piston crevice is from 2 to 2.3 times larger than that of fuel in the oil fim. However, fuel form oil film slowly desorbs into the combustion chamber compared with fuel from the piston crevices when the engines is cold.

It was grown ZrO2:10 mol% Y2O3 single crystals doped with 1 wt% of rare earth metal ion (Ce, Pr, Nd, Er, Eu) by Skull Method. Grown crystals showed Ce:orange-red, Pr:golden-yellow, Nd:lilac, Er:pink, Eu:light pink due to dopant effect. It was examined color centers in light absorption pattern of visible region (λ= 300~700 nm); in as grown samples, absorption by Ce4+, (Pr4+, Pr3+), Nd3+, Er3+, Eu3+ ions were important, and in samples after vacuum annealing, decrease of absorption by Pr4+ ion and increase of absorption by Pr3+ ion was important, and absorption by Ce3+, Eu2+ was important due to reduction of activator.

This study describes the results of Coefficient Of Performance(COP) analysis by cycle simulation for two types of absorption-compression hybride cycle using the water/Lithium Bromide solution pair, These types are basic hybride systems introducing a mechanical compression process into the refrigerant vapor phase of the single effect absorption cycle. In absorption-compression hybrid cycles, coefficient of performance is improved compared with absorption cycle. Hybride cycle Type ll is considered as a key technology to support energy utilization system, given its capability of utilizing waste heat to drive system with a high level of efficiency.
