This paper is aimed to explore the co-movement capital market in Southeast Asia and analysis the correlation of conventional and Islamic Index in the regional and global equity. This research become necessary to represent the risk on the capital market and measure market performance, as investor considers the volatility before investing. The time series daily data use from April 2012 to April 2020 both conventional and Islamic stock index in Malaysia and Indonesia. This paper examines the dynamics of conditional volatilities and correlations between those markets by using Multivariate Generalized Autoregressive Conditional Heteroscedasticity (MGARCH). Our result shows that conventional or composite index in Malaysia less volatile than Islamic, but on the other hand, both drive correlation movement. The other output captures that Islamic Index in Indonesian capital market more gradual volatilities than the Composite Index that tends to be low in risk so that investors intend to keep the shares. Generally, the result shows a correlation in each country for conventional and the Islamic index. However, Internationally Indonesia and Malaysia composite and Islamic is low correlated. Regionally Indonesia's indices movement looks to be more correlated and it's similar to Malaysian Capital Market counterparts. In the global market distress condition, the diversification portfolio between Indonesia and Malaysia does not give many benefits.

The purpose of this study was to investigate consumers' buying intention toward fashion goods through global internet shopping malls. This research employed Technology Acceptance Model (TAM) as a theoretical framework and was extended to introduce fashion innovativeness, clothing involvement, consumers' needs for uniqueness, computer self-efficacy as external factors. A total of 381 copies of questionnaires were collected online. The subjects of this study were women. The collected date were analysed by factor analysis, Cronbach's alpha, correlation and path analysis. The results indicated that fashion innovativeness, clothing involvement and consumers' needs for uniqueness had a significant positive affect on perceived usefulness. Consumers' needs for uniqueness and computer self-efficacy had a significant positive affect on perceived ease of use. Perceived usefulness and perceived ease of use were found to influence buying intention toward fashion goods through global internet shopping malls. The results of this study also suggested that perceived ease of use was actually a causal antecedent to perceived usefulness. This study reveled that employing TAM to investigate the buying intention toward fashion goods through global internet shopping malls was appropriate. This study also provides empirical analysis that can serve as a guide for marketers of the fashion industry in activating global internet shopping malls.

This study investigated the semantic network based on the focus of the fashion image and SNS text utilized by global SPA brands on the last seven years in terms of the quantity and quality of data generated by the fast-changing fashion trends and fashion content-based media environment. The research method relocated frequency, density and repetitive key words as well as visualized algorithms using the UCINET 6.347 program and the overall classification of the text related to fashion images on social networks used by global SPA brands. The conclusions of the study are as follows. A common aspect of global SPA brands is that by looking at the basis of text extraction on SNS, exposure through image of products is considered important for sales. The following is a discriminatory aspect of global SPA brands. First, ZARA consistently exposes marketing using a variety of professions and nationalities to SNS. Second, UNIQLO's correlation exposes its collaboration promotion to SNS while steadily exposing basic items. Third, in the case of H&M, some discriminatory results were found with other brands in connectivity with each cluster category that showed remarkably independent results.

Purpose - This study verified the mediating effect of volunteer activities in the influence of global citizenship consciousness on human rights sensitivity of university students majoring in business administration. Research design, data, and methodology - The survey was conducted on 172 4-year college students in G City, Korea. SPSS 23.0 program was used to perform frequency analysis, descriptive statistics analysis, correlation analysis, reliability analysis, and multiple regression analysis. In addition, path analysis was conducted to confirm the mediating effect of volunteer activities. Result - First, the "justice domain" had a statistically significant effect on human rights sensitivity. Second, the "cognitive domain" had a positive and significant effect on volunteer participation. Third, the volunteer participation of university students majoring in business administration had a positive and significant effect on human rights sensitivity. Fourth, in the relationship between global citizenship consciousness and human rights sensibility of university students, volunteer participation had a partial mediating effect. Conclusion - The period of college enrollment is an important time to establish life goals and strategies as adults. Therefore, if the university environment is built to grow into a healthy global citizen, it will help to cultivate global competence and the "sensitivity to human rights" that is more emphasized in the era of the 4th industrial revolution.

In this study, the rock mass classification results from the face mapping and the resistivity inversion data are compared and analyzed for the reliability investigation of the determination of the rock support type based on the surface electrical survey. To get the quantitative correlation, rock engineering indices such as RCR(rock condition rating), N(Rock mass number), Q-system based on RMR(rock mass rating) are calculated. Kriging method as a post processing technique for global optimization is used to improve its resolution. The result of correlation analysis shows that the geological condition estimated from 2D electrical resistivity survey is coincident globally with the trend of rock type except for a few local areas. The correlation between the results of 3D electrical resistivity survey and the rock mass classification turns out to be very high. It can be concluded that 3D electrical resistivity survey is powerful to set up the reliable rock support type.
