The rate constants for the reactions of p-nitrophenyl acetate with 6 different aryloxides and 2 benzohydroxamates have been measured spectrophotometrically in water containing various concentrations of cetyltrimethylammonium bromide (CTAB). The reactivity of the nucleophiles has been demonstrated to be significantly enhanced as the concentration of the surfactant increases up to a certain point. When the basicities of the aryloxides are comparable, the rate enhancement is more prominent for the aryloxide having larger binding constant to the micellar aggregate. Benzohydroxamates exhibitis significantly large ${\alpha}$-effect in the absence of the surfactant, although, the ${\alpha}$-effect nucleophiles are considered to be more solvated in water than the corresponding normal nucleophile. Thus, the solvation effect does not appear to be solely responsible for the ${\alpha}$-effect. Interestingly, the large ${\alpha}$-effect disappears in the presence of the surfactant. Therefore, one might attribute the disappearance of the ${\alpha}$-effect to solvent effect. However, a structural change of the reactive ${\alpha}$ -effect nucleophile into unreactive ones would also be considered to be responsible for the absence of the ${\alpha}$-effect in the present system.

PURPOSE: This study examined the effects of ankle kinesio taping on the balanced control capabilities of normal adults, stroke patients, and musculoskeletal patients. METHODS: One thousand articles were searched, and 100 of them were selected as taping papers. Subsequently, 33 papers classified according to balance, muscle strength and pain were analyzed according to the effect size and age group. RESULTS: The effect of ankle kinesio taping on balance control was examined by dividing the effect size into three groups according to the type of disease. Studies with normal adults had a large effect size of 1.213, whereas the effect size of stroke studies was .377, which was small. Studies on musculoskeletal disorders had a large effect size of 1.429. All three groups did not include 0 in the 95% confidence interval, indicating a significant effect. CONCLUSION: The effect of kinesio taping on balance control was positive in all subjects, including normal adults, stroke patients, and musculoskeletal patients. On the other hand, in terms of the effect size of kinesio taping on balance control, musculoskeletal patients and normal adults had larger effect sizes than stroke patients.

In this study, a cavity shape measurement experiment was conducted by changing the diameter and the angle of attack of a disk cavitator. Since the gravity effect is proportional to the cavity volume, the larger the cavity, the greater the effect. It is concluded that the gravity effect becomes smaller as the cavitation number decreases because of a short cavity maintaining time. The cavity centerline rises in case of the positive angle of attack and descends in case of the negative angle of attack. Since the effect of the angle of attack is inversely proportional to the square of the cavity radius, the effect of the angle of attack becomes dominant in the vicinity of the cavitator. It is judged that the horizontal section of the cavity centerline cannot be extended because the factors affecting the gravity effect and the angle of attack effect are different.

This study attempted to examine the structural relationship between the main factors that determine the intention to continue participation in yacht activities. Specifically, motivation for yacht activities was divided into achievement motivation, social motivation, escapist motivation, conspicuous motivation, and hedonic motivation, and the effect of each motivation on the satisfaction and continuous intention of yacht activities was examined. This study surveyed 338 ordinary people who were interested in yacht activities or had experience in yacht activities, and verified the main hypothesis through regression analysis. The main analysis results of this study are as follows. First, it was found that achievement motivation did not affect satisfaction. Second, it was found that social motivation had a positive (+) effect on satisfaction. Third, it was found that escapist motivation had a positive (+) effect on satisfaction. Fourth, it was found that the conspicuous motivation had a positive (+) effect on satisfaction. Fifth, it was found that hedonic motivation had a positive (+) effect on satisfaction. Sixth, it was found that the achievement motivation had a positive (+) effect on continuous intention. Seventh, it was found that social motivation did not affect continuous intention. Eighth, it was found that escapist motivation had a positive (+) effect on continuous intention. Ninth, it was found that the conspicuous motivation did not affect continuous intention. Tenth, it was found that the hedonic motivation had a positive (+) effect on continuous intention. Eleven, satisfaction was found to have a positive (+) effect on continuous intention. This study derived academic and practical implications based on the analysis results and proposed future research directions.

This study was conducted to provide basic data and insight into behaviors that result in increased continuous sales and competitiveness. This was done by examining the effect of personal involvement on customer satisfaction and trust, the effect of customer satisfaction on switching cost and loyalty, the effect of trust on switching cost and loyalty and by analyzing the indirect effect of trust and loyalty to personal involvement on switching cost and loyalty of the patrons of casual dining restaurants. In order to achieve the goals of the study, a hypothesis and structural equation were proposed based on preceding research and the proposed model was analyzed using LISREL 8.30 to prove the hypothesis and better understand the interactions between the cause and effect. The results were as follows: Six proposed hypothesis were chosen and the indirect effect was verified. In other words, customers' personal involvement was shown to have an effect on trust and devotion and satisfaction influenced switching cost and loyalty. Trust had an effect on switching cost and loyalty and by analyzing the indirect effect the customers' personal involvement was shown to affect the switching cost and loyalty through satisfaction and trust. The result of this analysis provides clues to better understand the eating-out behavior of customers and proves that personal involvement, satisfaction, trust, switching cost and loyalty are directly and indirectly related.

Purpose - The purpose of this study is to reveal the effect of a High Performance Work System(HWPS) on research performance. In addition, this study examines the mediation effect of Innovation Commitment(IC) and the moderated mediation effect of Perceived Organizational Support(POS), and seeks to reveal the antecedents and boundary variables that affect research performance. Design/methodology/approach - The level of analysis is at the individual level. A survey was collected from researchers at government-funded research institutes in the Daejeon and Sejong areas. 265 questionnaires were used in the final statistical analysis. Confirmatory factor analysis was performed using the AMOS 21. Correlation analysis, regression analysis, and bootstrapping by Process Macro were performed using the SPSS 19. Findings - As a result of the study, HWPS has a positive effect on IC, and IC has a positive effect on research performance. Through this results, it was found that IC mediates the relationship between the HPWS and research performance. In addition, POS positively moderated the mediating effect of HPWS on research performance through IC. Research implications or Originality - First, IC can be increased through a HPWS. Second, the effect of the HWPS on individual research performance through IC provides implications that the HWPS can be effectively applied not only to general companies but also to research organizations. Third, the boundary effect of POS was revealed. Fourth, research performance was measured through objective quantitative indicators rather than subjective.
