An effect of reward program related to promotional activity has the limitation of being concentrated on a short-term performance or of inducing temporary re-purchase. Accordingly, this study verified the influence of reward method upon consumers' response recovery centering on interactive effects of reward timing and reward intensity, in order to expand a research of dissatisfaction situation. As for the objective of this study, first, the aim is to verify the difference in the influence of economic, non-economic, and combined rewards, which are reward methods of dissatisfaction situation, upon consumers' cognitive response recovery and emotional response recovery. Second, the aim is to confirm a moderating role of reward timing and reward intensity in the effect of consumers' response recovery according to reward methods. To design a research, the perfect factor design between subjects in 3X2X2 was used. As a result of major research, first, there was a difference in the influence upon consumers' response recovery depending on reward methods. Second, the influence of reward method upon consumers' response recovery had a difference depending on reward timing. Third, the influence of reward method upon consumers' response recovery had a difference depending on reward intensity. Consumers' response recovery level was confirmed to have the greatest influence in the combined reward. This study has a significance in newly applying the reward timing, in the dissatisfaction situation which is addressed in the general reward program. Through this study, the aim was to support the empirically analytical results of prior researches and to expand its role in several angles.

It is well known that compensation satisfaction of employees is closely related to work attitude, job commitment, and employees'intentions to stay on the job. These known facts can also be applied to the professionals engaged in science & technology as well. Many studies have concluded that the Korea's losing competitiveness in the area of science & technology was mainly attributed to the distorted compensation system. In this vein, this paper identifies the potential determinants that affect the compensation satisfaction of S&T professionals, and to empirically examines the determinants influences on job commitment and intention to stay. This was done by acquiring data from S&T professionals currently being employed in firms, universities, and institutions. Consequently, for professionals engaged in science & technology, the compensation satisfaction was demonstrated to be largely influenced by job accomplishment, monetary compensation, and social compensation in order. In conclusion, to improve compensation system for S&T professionals, firstly, it is recommended to enhance job accomplishment by endowing more discretionary authority to conduct research. Secondly, the relatively lower-valued labor forces in S&T area will necessitate more economic support and compensation. Finally, the social compensation should be strengthened by not only ameliorating social status, but also improving labor liquidity and job security.

In general, industrial production involves large amounts of harmful by-product, causing serious pollution and ecological risk. Eco-efficiency, which indicates how efficient the economic activity is by considering both the environmental risks and economic performance, is a new concept for economic sustainability analysis and quantitative ecological risk analysis. Data envelopment analysis (DEA) has been widely used to examine eco-efficiency in recent years. Whereas traditional DEA models such as CCR and BCC model neglect undesirable outputs, this paper adopts a stochastic undesirable-output DEA model to measure the eco-efficiency of each province of China and Korea. The results indicate that whereas the eco-efficiency of the eastern region was the highest, that of the western region was the lowest. The reason may come from the negative external dis-economies of environment. And thus the governmental efforts for outreach on the underdeveloped regions should be promoted.

Recently, high performance concrete developed has a good quality at fresh and hardened state, but high binder contents results in spending much money on manufacturing and many cracks by drying and autogenous shrinkage, Therefore, in this paper, not only prevention of cracks caused by drying and autogenous shrinkage, but improvement of quality and accomplishment of economy by applying F.A(fly ash), S.F(silica fume) and CSA(calcium sulfa aluminate) expansive additives as an inorganic admixtures in W/B 35% are discussed. According to the experimental results, when 5% of CSA expansive additives and 15:5(F.A:S.F)are replaced at unit cement content, high performance concrete with both good fluidity at fresh state and high compressive strength, compensation of drying and autogenous shrinkage at hardened state are accomplished.

The objective of this study was to investigate the effect of the supplementation of antibiotics on meat quality grade of broiler carcasses under the Korean meat grading system. A total of 34,000 broiler carcasses, which were randomly selected 100 broilers from each farm in 340 broiler farms (305 farms with antibiotics; 35 farms without antibiotics), were used in this study. Average daily weight gain of broilers was not significantly affected by the use of antibiotics. The ratio of quality grade A was higher in the broiler carcasses from the farms with antibiotics supplementation (78.87%) than those without antibiotics (73.46%, P<0.05). The numbers of carcass defects, which are down-grade factors of meat grading system, were much higher in the broiler carcasses produced from the farms without antibiotics supplementation when compared with those with antibiotics. In particular, the incidence of the carcass defect on conformation was approximately 1.8 times higher in the carcasses from the farms without antibiotics supplementation than those with antibiotics, which showed the highest negative correlation with quality grade A. Therefore, the improvement of farm management system, the use of antibiotics alternatives from natural products, and a proper incentive should be considered in various ways to encourage farmers to reduce antibiotics usage in their farm and earn consumers' trust for antibiotics-free products.
