  • Online marketplace represents the triad relationship among the consumer, the intermediary, and the seller community. However there have been a limited number of studies conducted with the view of the triad relationship, which have produced contradictory and mixed results. The purpose of this study is (1) to find trust factors affecting consumers' transaction intention-trust in intermediary and trust in community of sellers, and (2) to investigate the directionality of trust transfer between those factors. To do this, the study sets and tests a bidirectional model. Based on the study results, the study discusses that both trust in intermediary and trust in community of sellers are important to consumers' transaction decision in online marketplace, and trust transfer in online marketplace flows from intermediary to community of sellers.

  • In this paper we: (1) analyze the relationship among public R&D investment, private R&D investment, and GDP by employing the Clangor causality test; (2) examine if there is any country-specific pattern in the relationship by testing the cases of Korea, the U.S. and Japan. We found some common results for the above countries as follows: (i) GDP causes Public R&D, not vice versa; (ii) Private R&D causes GDP; and (iii) Public R&D does not cause Private R&D. For the bivariate model of GDP and total R&D, the results show the existence of one-way causality running from total R&D to GDP f3r both U.S. and Japan. We also found bidirectional causal relationship between GDP and total R&D for Korea, which could be interpreted as a typical pattern for newly industrialized countries.

  • Primary cilia and autophagy are two distinct nutrient-sensing machineries required for maintaining intracellular energy homeostasis, either via signal transduction or recycling of macromolecules from cargo breakdown, respectively. Potential correlations between primary cilia and autophagy have been recently suggested and their relationship may increase our understanding of the pathogenesis of human diseases, including ciliopathies and cancer. In this review, we cover the current issues concerning the bidirectional interaction between primary cilia and autophagy and discuss its role in cancer with cilia defect.

  • Recently, in the research on online environment such as e-commerce, and internet banking, the conceptual discussion about trust and risk in an effort to explain a user's behavior is briskly underway. Most of the research on trust and risk are setting up causal relationship without clearly establishing the relationship between trust and risk. Accordingly this study conducted a meta-analysis in order to consider the relationship between trust and risk and to take a look at the difference in causal relationship. This study includes a total of 18 research papers which are setting up the causal relationship between trust and risk in online environment among the research papers published in domestic academic journals since 2000. Result of the meta-analysis, showed that the effect size was -0.367 in the path from trust to risk; -0.131 in the path from risk to trust; -0.276 in the bidirectional path between trust and risk. In addition, this study was able to confirm through literature review that there appeared a high effect of path in case where trust and risk were measured by an uni-dimensional concept than by a multi-dimensional concept.

  • 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.

  • We have proposed and experimentally demonstrated a novel fiber Bragg grating (FBG) sensing interrogation method using bidirectional modulation of a Mach-Zehnder electro-optical modulator (MZ-EOM). The proposed structure consists mainly of a broadband light source (BBS), FBG, MZ-EOM, chirped fiber Bragg grating (CFBG), and photodetector (PD). We have obtained the transfer functions of the proposed structure and calculated the time delay from the change in the free spectral range (FSR) for ten wavelengths over the frequency range of 505 MHz to 525 MHz. The results show that the time delay and the wavelength variation have a good linear relationship with a gradient of 12.9 ps/0.2 nm, which can be usefully applied to FBG strain or temperature sensors and other multiplexed sensor applications.

  • This study investigates the contribution of customer knowledge to customer intention to adopt mobile banking by evaluating the interaction among knowledge, perceived risk and trust, and behavioral intentions. Analysis is conducted through structural equation modelling using SPSS and AMOS and data from 783 customers representing the seven largest banks in Vietnam. Our study is the first one to find the existence of the bidirectional perspective between objective and subjective knowledge. The study further shows that the attenuation effect in the heuristic-systematic model could be used to explain the stronger influence of objective knowledge on intention compered to subjective knowledge. Our findings suggest that customer knowledge, perceived risk and trust impact the intention of mobile banking users in different manners and to different degrees. Particularly, objective customer knowledge is the most influential predictor of mobile banking adoption. Having a greater understanding of these relationships can help firms in deciding the kind of intervention that is most likely to convince customers to adopt a service.

  • Isozyme was used to characterize general protein patterns of genetic relationships among 303 silkworm stocks preserved in National Sericultural and Entomology Research Institute, RDA. Six isozymes (esterase, acid phosphatase, alkaline phosphatase, amylase, glucose-6-phosphate dehydrogenase and sucrase) from hemolymph, midgut, and digestive juice were employed to construct dendograms(UPGMA method) using a polycrylamide gel electrophoresis. A cluster analysis revealed four major group, which were divided into several subgroups within each group, contained assemglages of Japanese and Chinese races. Especially, genetic differentiation in the first and second group was greatest rather than within Japanese and Chinese races repectively and was concordant with the hypothesis of phyletic sorting of initial variability in China many years ago. Hypothesized recent introgression between groups was also plausible, but the eviednce suggested bidirectional gene flow between the Chinese and the Japnaese lineages. Interpreting the results in light of evidence from the current study, the genetic diversity and relationship showed in Korean silkworm race, Hansammyun reflected early and independent evolution from the Chinese ancestor, limited addition of new variability and phyletic sorting within Korean peninsula more than 4,000 years.

  • This study attempts to investigate the effects of different types of debts on economic growth in Bangladesh using time series data spanning from 2000 to 2015. In this study, the RDL model has been applied to determine the long run relationship among the selected variables. The result of the ARDL model shows that there exists a long term relationship between economic growth and the debt variables. It was evident from the findings that there exists bidirectional causality between public sector external debt and economic growth. Causality between private external debt and economic growth has been found to be insignificant. However, causality between domestic debt and economic growth showed a unidirectional causality from domestic debt to economic growth and not vice versa. Causality tests suggest that impact of domestic debt on economic growth is more effective compared to external debts.

  • Studies on the development of various energy management programs and real-time bidirectional information infrastructures have been actively conducted to promote the reduction of power demands and CO2 emissions effectively. In the conventional energy management programs, the demand response program that can transition or transfer the power use spontaneously for power prices and other signals has been largely used throughout the inside and outside of the country. For measuring the effect of such demand response program, it is necessary to exactly estimate short-term loads. In this study, the power consumption patterns in both individual and group consumers were analyzed to estimate the exact short-term loads, and the relationship between the actual power consumption and seasonal factors was also analyzed.
