  • The concrete structures possessing good structural integrity can face durability problems due to deteriorations of concrete structures under various environmental conditions. The durability problems weaken the structural integrity in the long run. Especially, the excessive use of sea sand causes serious reinforcement corrosion and carbonation in concrete structures. An accelerated test is often used to predict deterioration as a qualitative measure, but without long term exposure test results or understanding of the relationship between the accelerated test and the long term exposure test, the accelerated test result alone can not be used effectively as a quantitative measure. In this paper, a methodology is proposed to predict the long term deteriorations, based on the result of the short-term accelerated test, of concrete containing different contents of chloride ions. Then, the correlation between two results on the steel corrosion ratio and the carbonation depth is analyzed for concrete with different chloride contents.

  • In recent years, a significant number of empirical studies have examined the relationship between export and economic growth in India. However, this study analyses the relationship between exports and economic growth through the time series model. The main aim of this study is to investigate the causal relationship between exports and economic growth in India. The VAR model was used for the period 1961 to 2015 after verifying the stationarity of the variables through using Augmented Dickey-Fuller and Phillip-Perron tests. The Indian export sector has been found to have a significant and positive impact on economic growth and other long-term economic activities. The study also employed the Granger causality test to check the direction of causality and found that RXGS, RGDP, RPFC, and RGFC had a unidirectional relationship and RXGS and RMGS had a bidirectional relationship in long run. Also, the findings of this study suggest that a steady-state between exports and economic growth can be achieved in India over a long period. The overall outcome of this study provides a testimony of the fact that the export sector plays a vital role in economic growth in India and also leads to the long-term growth of other economic activities.

  • Purpose - This study aims to determine the effects of marketing factors on the long-term purchasing behavior regarding industrial goods, using data from wholesalers and retailers. Research design, data, and methodology - We used multiple regression analysis and 3-step regressions to investigate causality. We used 177 questionnaires targeting wholesalers and retailers of industrial goods. Results - First, long-term purchasing behavior is positively related only with advertising and marketing factors. Second, the relationship between marketing factors and brand value show that the physical environment, word-of-mouth advertising, and publicity are positively related, except advertising and sales promotion, respectively. Third, brand value and long-term purchasing behavior are positively related. Finally, brand value is not a mediator between marketing factors and long-term purchasing behavior. Conclusion - This study suggests that industrial goods providers should use marketing strategies that are different from those used in the consumer market. Further, if they want to maintain long-term relationships, they should increase their brand value.

  • Purpose: This study was to analyze the factors that affect the service relationship of long term care workers for the elderly and to provide basic resource for the successful connection of long term care services. Methods: 259 subjects who were engaged in long term care units completed a self-administered questionnaire that measured the extent of service linkage among one another. The Cronbach's ${\alpha}$ score determined the internal consistency of the acquired data and the discriminated validity was estimated by Pearson's correlation coefficient. Multiple regression analysis was conducted to investigate the influence of the known factors on the service linkage. Results: Acceptance and participation negatively influenced on the service linkage. Reliance, comprehension, recognition on service, and frequent contact with others positively activated the service linkage of long term care workers. Conclusion: The establishments of systemic training courses providing education that emphasizes reliability and recognizes other services, including work environment to contact easily are needed to improve the service-linkage of long-term care workers for the elderly.

  • For a long cable-stayed bridge, stay cables are its most important load-carrying components. In this paper, long-term monitoring of super-long stay cables of Sutong Bridge is introduced. A comprehensive data analysis procedure is presented, in which time domain and frequency domain based analyses are carried out. In time domain, the vibration data of several long stay cables are firstly analyzed and the standard deviation of the acceleration of stay cables, and its variation with time are obtained, as well as the relationship between in-plane vibration and out-plane vibration. Meanwhile, some vibrations such as wind and rain induced vibration are detected. Through frequency domain analysis, the basic frequencies of the stay cables are identified. Furthermore, the axial forces and their statistical parameters are acquired. To investigate the vibration deflection, an FFT-based decomposition method is used to get the modal deflection. In the end, the relationship between the vibration amplitude of stay cables and the wind speed is investigated based on correlation analysis. Through the adopted procedure, some structural parameters of the stay cables have been derived, which can be used for evaluating the component performance and corresponding management of stay cables.

  • Purpose: As a major economy attracting foreign investment, China is currently facing significant international economic pressure due to the appreciation of the RMB. Additionally, China is at a critical period of socio-economic development, where foreign direct investment (FDI) plays an indispensable role in stabilizing economic growth, adjusting industrial structure, and promoting economic transformation. Research design, data and methodology: This paper focuses on the relationship between RMB exchange rate expectations and FDI. It examines the magnitude of their relationship through empirical research using cointegration tests, Granger causality tests, and BVAR (Bayesian Vector Autoregression) analysis. Results: The comprehensive study of the empirical results in this paper concludes that there is a long-term cointegrated relationship between China's RMB exchange rate expectations and foreign direct investment, indicating that their relationship is stable in the long run. It is also found that RMB exchange rate expectations have a significantly positive impact in the short term, but this impact is not significant in the long term. Conclusions: The paper also considers the possibility of establishing a China-EU Free Trade Area in the future and offers policy recommendations regarding RMB exchange rate expectations and foreign direct investment.
