C-terminus specific immobilization often results in a increased structural stability resistant to various denaturation factors. In order to elucidate the immobilization effect on the c-terminus in molecular level, we made over 200 protein data set from Protein Data Bank(PDB), analyzed c-terminus structure of each protein, and investigated the structural relationship with the stabilizing factors such as hydrogen bond, ion pairs, cation pi, disulfide bond, solvation free energy, surface area, flexibility and so on.

This paper addresses modeling of the gyro drift by using the structure function approach which has been originally developed for characterization of the oscillator phase noise. It is shown that by using this approach, an arbitrary order of random and deterministic gyro drift processes can be characterized and easily measured. The relationship between the drift power spectral density and structure function is clarified. It is also shown that this approach simplifies analysis of the effect of drift on the control system performance.

The Internet can provide benefits obtained from changing the structure of a business, such as emphasizing the importance of different types of personnel. In addition, the Internet alters the process for business activity, both within and outside the organization. Using structural equation modeling, I empirically test a number of hypothesized relationship based on a sample of 126 Internet Community users. The results are as follows: loyalty is significantly influenced by trust and relationship, repeat purchase is significantly influenced bye-loyalty. In addition, word of mouth is significantly influenced by e-loyalty.

This article addresses how an organization's customer relationship management (CRM) process affects customer equity drivers and, in turn, organizational performance. By raising a three-staged model including the CRM processes, customer equity drivers, and organizational performance, the authors assert that the customer equity drivers mediate between the CRM processes and organizational performance. The empirical analysis is based on a composite survey structure that gathers data from different types of informants according to the variables. Findings indicate that the expansion process has positive relationship with all the customer equity drivers. However, the acquisition process significantly influences both perceived value equity and brand equity, and the retention process significantly influences relationship equity only. In addition, the study shows that all the customer equity drivers influence the organizational performance given the existing customers. The relationship equity among the customer equity drivers has the strongest effect on the performance.

The purpose of this study was to examine the role of profitability as a mediating variable in influencing firm value. This study uses a sample of manufacturing companies listed on the Indonesia Stock Exchange from 2016 to 2018. The data used is panel data, with data analysis using multiple regression. Based on the Sobel test, profitability plays a role in mediating the effect of firm size on firm value. The effect of firm size on firm value is indirect, however, through profitability. Therefore, the market price of the shares of large-scale companies will increase if the resulting profitability is high. The capital structure and managerial ownership directly influence firm value. The results showed that managerial ownership and firm size had a positive effect on profitability, while capital structure had no effect on profitability. Capital structure and managerial ownership have a negative effect on firm value, while firm size and profitability have a positive effect on firm value. The main finding of this study is that profitability acts as an intervening variable in mediating the relationship between firm size and firm value.

Purpose - This study's objective is to confirm the effects of the perceived relationship value, alternative attractiveness, and investment size on Korean food service franchisees' commitment, using an investment model. Among the three factors, the study examines which factors enhance or weaken the commitment in the franchising investment model. Research design, data, methodology - The data were collected from 495 franchisees and analyzed by a SEM (Structure Equation Model) using path analysis by SPSS 18.0 and AMOS 18.0. Results - 1) The perceived relationship value has a positive effect on franchisee commitment. 2) The alternative attractiveness has a negative effect on franchisee commitment. 3) The investment size has a positive effect on franchisee commitment. Conclusions - The findings show that the investment model can be adapted to franchising and confirms previous investment model study results. We can assume that the higher the perceived relationship value and the bigger the investment, the stronger the commitment, and the greater the alternative attractiveness, the weaker the commitment. These results offer managerial implications for a franchisor wanting to strengthen franchisee commitment.

The purpose of this study was to identify dynamic relationship structure in fashion Internet shopping mall and to present marketers to perform marketing strategy in e-CRM, focusing on trust and commitment. 473 customers who had purchased fashion products in fashion internet shopping mall had participated in the survey. Finally, 470 were used into data analysis. The data was analyzed by factor analysis, t-test, ANOVA, correlation analysis and Structural Equation Model(SEM) using AMOS program. As the results, 'economic benefits' and 'service' variables had the positive effects on 'trust'. Especially, 'service' had the major effect on 'trust'. 'Trust' and 'product information quality' had the positive effects on 'emotional commitment'. 'Trust', 'economic benefits' and 'reputation' had the positive effects on calculus commitment, while contents had the negative effect. Also, 'emotional' and 'calculus' commitment had positive effects on 'relationship maintenance intention'. 'Emotional commitment' had higher effect on 'relationship maintenance intention' than 'calculus commitment'. 'Calculus commitment' had the positive effect on discontinue relationship intention when shopping mall made mistakes. The results of this study provide e-CRM marketing strategy for marketers of fashion internet shopping mall.

In this study, the applicability of PVDF films for measurements of dynamic strain in a structure was investigated. A relationship between the strain and the voltage response of a PVDF film was analytically derived. Free vibration test on a steel cantilever beam was performed and vibration response of the beam was measured both by a convential foil strain gauge and a PVDF film. Strain-voltage relationship obtained from the experiment was compared with the analytic relationship. Good agreement between the analytic and experimental relationships was observed. It was found that a tailored PVDF film can measure the dynamic strain of a structure as accurate as a conventional foil strain gauge.

This paper was performed to investigate the effect of pore structure on ink residual behavior. To prepare different coating structures as substrates against inks, fine, medium and coarse calcium carbonate were used in the coating color. It is well known ink properties can affect to print qualities. After printing on the coated paper, ink layer can consider as third structure addition to paper and coating layer. To compare effect of ink properties on the surface structure and print qualities, several properties of ink were also adopted as raw material. Particle size of pigment effect on gloss evaluation of coated paper increased with calendering. It was shown that ink transfer rate increased as surface of the sample was smooth. The ink contained low viscosity resin evaluated more print gloss. Finer pigment particle size, smaller pore size and higher porosity. Pore volume of coated paper was slightly decreased with printing as the coating was prepared with the finest particle size. However, it founded that ink resin could not affect on pore volume and distribution of printed paper

Experimental wind tunnel tests have been attempted to investigate the aerodynamic characteristics of floating offshore structure using some types of scaled mldels. The static behaviors of lift, drag forces and pitching moment of its models are measured to exammine the relationship between wind loads and incidence angle, wind velocity, shape of models. The effect of solid ground has been obtained also.
