The objectives of this study are to identify significant antecedents of trust and satisfaction and to examine the relationship between trust and satisfaction and interrelationship between trust, satisfaction, loyalty, relationship retention and intention of words of mouth based on buyers of Chinese internet shopping mall. The questionnaire was collected by personal interview. A total of 448 completed questionnaires were collected. Confirmatory factor analysis was conducted to test the validity of the measurement model, and the structural model also was analyzed to examine the associations hypothesized in the research model. This study uses AMOS program to investigate the research model. Results in this paper indicate that the antecedents of trust and satisfaction have three dimensions, namely communicational, traditional and relational factors. All these three functions are positively related to trust and satisfaction. Also the results show that trust and satisfaction are positively related to loyalty, relationship retention and intention of words of mouth. Finally, this study suggests the implications of these findings and offers directions for future research.

Retention behaviors of aliphatic and aromatic compounds were investigated with Van der Waals volume which represented the molecular size. The organic solvents, methanol, acetonitrile and tetrahydrofuran, were mixed with water at various ratio, respectively. The selectivity of organic solvents were tested by change of column temperature. The capacity factor was increased linearly according to the enlargement of molecular size. Therefore, Van der Waals volume was useful to predict the elution of organic molecules in reversed-phase column. The order of elution capacity of solvents was methanol

In the current competitive marketplace of real estate business, tenant satisfaction measurement is one of the important indicators to monitor competitiveness in industrial property development. It has become an industry standard to measure tenant satisfaction, commonly called customer satisfaction. Customer satisfaction has become the widely used metric to manage customer loyalty (Keiningham, Gupta, Aksoy, & Buoye, 2014). The aim of this research is to determine the impact of property management services on tenants' satisfaction with the three identified variables i.e. facility management, perceived quality and lease management. Structural equation modeling (SEM) is applied to build constructs and test the hypotheses with the collected survey samples. Of the three variables, facility management is the most influential factor that leads to tenant satisfaction with industrial buildings. Next, perceived quality is another important factor that contributes to tenants' pleasure. Compared with these two, lease management fares worse, having the least extensive effect on tenant satisfaction, and could be disregarded. The ultimate impact of tenant satisfaction is about tenant retention and recommendation. The overall findings of this research will potentially help real estate developers to develop a better property management system, leasing program and tenant retention strategy.

Aviation industry, which is highly dependent on human resources, emphasizes airline's human resources management and performance check because quality of services provided to customers is closely related to airline's employees. Because roles of cabin crews take a significant portion of services provided to customers, airlines and cabin crews represent an inseparable relationship. Attitudes of cabin crews who plays the role of facing and dealing with customers directly in the process of providing flight related services are an essential factor that determines an image of an airline and actually have significant impact on the performance as well. By increasing performance satisfaction of cabin crews, organizational loyalty can be strengthened and such successful human resources management could have a positive effect on increasing customer satisfaction as well as revenues. From corporate's perspective, performance satisfaction of an employee is a crucial factor that decides the quality of service provided to customers that supports employee retention as well as client retention. This can eventually lead to organization loyalty that can positively affect overall work performance. Thus if corporates put efforts in and invests to improve and develop favorable attitudes and service quality within employees, performance satisfaction and organizational goals will be more effectively achieved.

Recently, liquid chromatography (LC) has been used more frequently to separate drugs and natural substances. Especially, to selection of the solutes from the products, the operation condition of analytical chromatography should be necessarily determined. So accurate computer modeling and simulation of chromatographic performances has become a necessary part of the development and design of processes. High-Purity Separation Lab. Inha University developed the resulting HCI software for the purpose of the optimization of chromatographic performances. The HCI program was utilized to find the optimum operating condition more accurately and rapidly, reducing the number of many possible experiments. The elution profiles were calculated by the plate theory based on the three retention mechanism of capacity factor.

Accurate measurements of ozone precursors are required to understand the process and extent of ozone formation in rural and urban areas. Nonmethane hydrocarbons (NMHCs) have been identified as important ozone precursors. Identification and quantification of NMHCs are difficult because of the large number present and the wide molecular weight range encountered in typical air samples. A major plan of the research team of the Climate and Air Quality Taiwan Station (CATs) was the measurement of atmospheric nonmethane hydrocarbons. An analytical method has been development for the analysis of the individual nonmethane hydrocarbons in ambient air at ppb (v) and subppb(v) levels. The whole ambient air samples were collected in canisters and analyzed by GC-FID with $Al_2O_3$/KCl PLOT column. Our targeted for quantitative analysis 43 compounds that may be substantial contributors to ozone formation. The retention indices and molar response factors of some commercially available $C_2{\sim}C_{10}$ hydrocarbons were determined and used to identify and quantify air samples. A quality assurance program was instituted to ensure that good measurements were made by participating in the International Nonmethane Hydrocarbon Intercomparison Experiments (NOMHICE).

The objectives of this research are to examine the factors influencing the employees' satisfaction and to investigate that the employees' satisfaction effects the organizational commitment on seven National University's hospitals. The data for this analysis were collected by questionnaire survey. 657 usable questionnaires were returned, a 78.2%, response rate. The major statistical methods used for the analysis are factor analysis, t-test and hierarchical multiple regression. The findings suggest that four components of job satisfaction are selected: these are "task", "organizational operation system", "opportunity of development", "interpersonnel". Highly satisfied employees turn to organizational commitment such as responsibility of organization and retention. Futhermore the findings suggest that responsibility is affected by work period, task satisfaction, opportunity of development. And retention is affected by work period, role as teaching hospital, and task satisfation. This study concludes with a discussion of the managerial relevance of the findings and future research directions.

Ionic liquids in the form of organic salts are being widely used as new solvent media. In this paper three positional isomers, o-amino benzoic acid, m-amino benzoic acid, and p-amino benzoic acids were separated with four different ionic liquids as mobile phase additives using high performance liquid chromatography (HPLC). The following ionic liquids were used: 1-butyl-3-methylimidazolium tetrafluoroborate ([BMIm][$BF_{4}$]), 1-ethyl-3-methylimidazolium tetrafluoroborate ([EMIm][$BF_{4}$]), 1-ethyl-3-methylimidazolium methylsulfate ([EMIm][MS]), and 1-octyl-3-methylimidazolium methylsulfate ([OMIm][MS]). The effects of the alkyl group length on the imidazolium ring and its counterion, and the concentrations of the ionic liquids on the retention factors and resolutions of amino benzoic acid isomers were tested. The results of the separations with ionic liquids as the eluents were better than those without ionic liquids. Excellent separations of the three isomers were achieved using 2.0-8.0 mM/L [OMIm][MS] and 1.0-8.0 mM/L [EMIm][MS] as the eluent modifiers.

BACKGROUND: The personal protective equipments (PPEs) is the most important factor for reducing the pesticide exposure during the preparation and spraying of pesticides. This study was to investigate the retention, repellence and penetration of protective clothing of PPEs according to the ISO 22608 'Liquid penetration resistance-pipette test. Protective clothing for agriculture worker is very important for their health. However, test method for measurement of protective clothing is not presented in Korea. METHODS AND RESULTS: In order to measure the retention, repellence and penetration of protective clothing, a apparatus for pipette method in accordance with the ISO Guideline was prepared. The test was conducted at $25{\pm}5^{\circ}C$, $60{\pm}10%$ of relative humidity and pipette applied to a apparatus was validated to take exact amount(0.2 mL). The retention, repellence and penetration of five types of protective clothing and one type of shirt were analyzed by GC/MS. Pendimethalin(5% a.i, emulsion) was used as a test pesticide to measure above factors. The retention were less than 11.0% with the exclusion of two types(F4 and shirt) and the repellency was more than 67.0% with the exclusion of shirt material. The penetration was less than 5.4%, however, that of shirt was 66.7%. CONCLUSION: This results indicated that all protective clothing were suitable to use as PPEs according to the criteria specified by ISO Guide 22608. However, shirt was not suitable due to high penetration. This test method established for measurement the retention, repellence and penetration of protective clothing will help to establish the test notice of pipette method.
