Rapid Prototyping(RP) techniques have unique characteristics according to their working principle: the stair-stepped surface of a part due to layer-by-layer stacking, low building speed, and additional post-processing to improve surface roughness. A new RP process, Variable Lamination Manufacturing by using expandable polystyrene foam(VLM-S), has been developed to overcome the unfavorable characteristics. The objective of this study is to investigate the thermal characteristics and skeleton size effects as the hotwire cuts EPS foam sheet in order to improve dimensional accuracy of the parts, which is produced by VLM-S. Empirical and analytical approaches are performed to find the relationship between cutting speed and heat input, and the relationship between maximum available cutting speed and heat input. In addition, empirical approaches are carried out to find the relationship between cutting error and skeleton size, and cutting deviation and skeleton size. Based on these results, the optimal hotwire cutting condition and available minimum skeleton size are derived. The outcomes of this study are reflecting in the enhancement of VLM-S input data generation S/W.

Purpose - The purpose of this study is to examine the impact of leader-member exchange (LMX) on employees' behaviors as well as to test the mediating roles of feeling trusted in the relationships. Research design, data, and methodology - Survey data were collected and analyzed from 285 sales people who work for various organizations in eastern China. The corresponding research models were verified using SPSS 22 and Amos 22. Results - The empirical results show that LMX plays a positive role in job performance and is positively related with subordinate's feelings of trust. However, the study was shown to have negative correlations between LMX and workplace ostracism. Feeling trusted by superiors mediated the relationship between LMX and job performance, resulting in employees being more motivated to do better, creating a positive synergetic effect. However, this relationship did not show to have significant mediating effects on the relationship between LMX and workplace ostracism. Conclusions - This study further enriches the relevant theory of LMX and has significance for management practices such as distribution sectors, guiding leaders to create a suitable team atmosphere. Leaders need to pay attention to build a high quality LMX with employees based on the empirical results of this study.

The objective of this research is to validate the BRQ(Brand Relationship Quality) Construct perceived by fashion product consumers. In order to establish and verify the BRQ scale, qualitative survey and quantitative survey were conducted together. 1592 copies of questionnaire were distributed to women in their 20s to 40s living in Seoul and other metropolitan areas from Dec. 26, 2005 to Jan. 8, 2006, and 723 copies of them were used for statistical data. Samplel(n=482)was used for empirical analysis, and sample2(n=241) was used for cross validity test. The data was analyzed using Exploratory Factor Analysis, Confirmatory Factor Analysis, and Pearson's Correlation Analysis. BRQ emerged from exploratory factor analysis as the hierarchical construct composed of six facets including 'self-connective attachment', 'symbol/mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge'. As the fit of this structural model was not good as a result of Confirmatory Factor Analysis, it was revised to have better fitting. Finally, empirical survey results indicate the hierarchical construct consisting of eight distinct BRQ facets including 'love/commitment', 'self-connection', 'symbol', 'mystery', 'trust', 'nostalgia', 'intimacy', and 'knowledge' as best representing the final 39item BRQ Scale. Reliability, construct validity, and cross validity of the construct were verified.

We examine whether the observational stand-off distance ratios of CMEs and their associated ICMEs could be explained by theoretical model or not. For this, we select 16 CME-ICME pairs from September 2009 to October 2012 with the following conditions: (1) limb CMEs by SOHO and their associated ICMEs by twin STEREO spacecraft and vice versa when both spacecraft were roughly in quadrature; (2) the faint structure ahead of a limb CME is well identified; and (3) its associated ICME clearly has a sheath structure. We determine the observational stand-off distance ratios of the CMEs by using brightness profiles from LASCO-C2 (or SECCHI-COR2) observations and those of the ICMEs by solar wind data from STEREO-IMPACT/PLASTIC (or OMNI database) observations. We also determine the theoretical stand-off distance ratios of the CME-ICME pairs using semi-empirical relationship based on the bow shock theory. We find the following results. (1) Observational CME stand-off distance ratio decreases with increasing Mach number at the Mach numbers between 2 and 6. This tendency is consistent with the results from the semi-empirical relationship. (2) The observational stand-off distance ratios of several ICMEs can be explained by the relationship.

It is the recent trend that the valuation criteria on product quality depends on the customer satisfaction instead of conformance to specifications. It also applies to the service quality. This study deals with an empirical study on the relationship between service quality and value and customer behaviour in the medical service industry. This study also investigates the effect of service-related quality on the service quality/value and customer behaviour. A statistical research reveals that 1)the service quality and value each has a positive relationship with customer behaviour, 2)the service-related quality strongly influence the service quality/value and customer behaviour.

This article aims to examine the one-way relationship between corporate social responsibility (CSR) and the financial performance of Vietnamese commercial banks, mainly focusing on the moderating role of ownership structure. Net interest margin (NIM), return on assets (ROA), and return on equity (ROE) are selected to represent the financial performance of the bank. CSR was measured using a multi-method approach that included both quantitative and qualitative methods. Corporate Social Responsibility Expenditure (CSRE) was estimated using financial data. The Corporate Social Responsibility Disclosure (CSRD) index was created using the content analysis method. Using a sample of Vietnamese commercial banks from 2012 to 2019 to perform regressions in the dynamic panel models with the two-step system generalized method of moments (GMM) estimator, the results show a positive effect of both CSRE and CSRD on the financial performance of the bank. Empirical evidence shows that the positive relationship between CSRE and financial performance is more robust in statecontrolled banks than non-state-controlled banks. In contrast, the positive impact of CSRD on the financial performance of state-owned commercial banks is weaker than that of private banks. Finally, the paper points out the limitations and proposes future research directions.

The current research aims to examine how workplace ostracism influences employee turnover-oriented intention and investigates the mediating role of job burnout in the workplace ostracism - turnover relationship. Drawing on conservation of resource theory, we hypothesize that higher levels of workplace ostracism develop employee turnover through job burnout. Precisely, we predict that workplace ostracism is positively associated with turnover intention, both directly and indirectly via job burnout. To test our theoretical model, we collected field data from 311 banking employees in Pakistan. Structural equation modeling is used to test the relationship between workplace ostracism and employee turnover intention. The empirical findings reveal that workplace ostracism is positively associated with turnover intention. Furthermore, the relationship between workplace ostracism and turnover intention is mediated by job burnout. By using job burnout as a mediator, the present study sheds light on "why" workplace ostracism is related to employee turnover intention. In doing so, the present research provides a comprehensive understanding of the negative effects of ostracism on the workplace. This has subsequently provided practitioners with new insight into how to reduce employee turnover in organizations. We conclude by discussing the future directions and practical implications of our study.

This study aims to investigate the relationship between urbanization, economic growth, energy consumption, and CO2 emissions in Indonesia. The data used in the study are time-series data for the period 1985-2017; the data utilized are sourced from World Development Indicators obtained on the World Bank database. The method uses a quantitative approach that applies the vector error correction model based on the Granger causality test. The empirical results reveal that, in the short run, there is evidence that urbanization and energy consumption can causes CO2 emissions, and they also prove that urbanization can cause energy consumption. Also, other findings prove the existence of long-run relationships flowing from energy consumption, economic growth, and CO2 emissions toward urbanization, as well as the existence of the relationship flowing from urbanization, economic growth, and CO2 emissions towards energy consumption. The results of testing the relationship between economic growth and CO2 emissions reveal that the environmental Kuznets curve hypothesis is proven in Indonesia. Thus, policies are needed to limit the impact of urbanization through high awareness-raising to maintain environmental quality and greater use of energy. Also, energy conservation policies are needed in all sectors, especially the electricity, industry, and transportation sectors.

For many years, many academics and practitioners have paid attention to the increasing popularity of corporate social responsibility (CSR) and its relationship with financial performance. They have shown that creating social and sustainable responsibility can strengthen the organization's financial performance as the organization can achieve its current needs without compromising the ability to meet future needs. While much theoretical and empirical evidence has been provided to support this argument in developed countries, this topic is under-researched, and the outcomes are controversial in developing countries. Therefore, this paper aims to examine and investigate the relationship between corporate social responsibility and financial performance in Vietnamese organizations. The dataset includes 27 firms listed on the stock market exchanges in Ho Chi Minh city (HOSE) and Hanoi (HNX) from 2015 to 2019. The disclosure approach is adopted to measure corporate social activities; four areas were developed: environment, community, employee and product, customer, and supplier practices. Return on average equity (ROE) and return on average assets (ROA) are two proxies for measuring financial performance. The research results confirm the existing literature with a strong correlation between employees and returns on average assets.
