The growth of the Islamic finance sector has been well-documented. One of the most booming sectors has been Sukuk. According to several past studies, non-Islamic investors' interest in Sukuk is due, at least in part, to the diversification benefits that Sukuk provides in the context of a fixed-income portfolio. This paper compares a pair between Sukuk and Bonds in the Malaysian market issued by the same issuer to have an unbiased comparison. Using unconditional correlation methodology provides an initial examination of the relationship between the matched pairs. In addition, this paper adopts the standard GARCH-DCC approach of Engle (2002). This is a generalization of the Bollserslev (1990) GARCH model, allowing for the conditional correlation matrices to be time-varying. The findings reveal that the correlation between bonds and Sukuk is similar to that of bonds, making Sukuk a less appealing type of bond from a diversification standpoint. There are no significant differences between Sukuk and bonds. These finding questions the previously considered differences among different types of Sukuk and supports the argument that some Sukuk might not be compliant with Islamic rules and their structure, as contracts have the same risks for Sukuk holders regardless of the type of Sukuk.

This study aimed to investigate the existence of the Feldstein-Horioka (1980) puzzle in international macroeconomics by applying the conditional Autoregressive Distributed Lag (ARDL) model to examine the long-run relationship between national savings and investments in Thailand and China. The input of this study relied on annual national savings and investments as a fraction of GDP during 1980-2019 which was collected from China National Bureau of Statistics (NBS) and Thailand National Economic and Social Development Council (NESDC). Hypothetically, Augmented Dickey-Fuller (ADF) and Phillips-Perron (PP) unit root tests were applied to test the stationary properties and to investigate the integration level of selected time series. The empirical results, confirmed by cumulative sum (CUSUM) and cumulative sum square (CUSUMSQ), maintained no serial correlation and structural break problems. The finding of this study suggested that the Feldstein-Horioka puzzle in Thailand did not exist significantly. Thailand's national savings and investments nexus was independent, following the classic economic idea that financial liberalization, or perfect capital mobility, allowed national savings and investments to flow freely to countries with better interest rates. Whereas, a strong significant correlation was found in the case of China during the fixed exchange rate regime switching in 1994 and post WTO participation after 2001-2019.

Background and objective: This study examined, compared, and analyzed the tree vitality of the trees growing on the artificial ground of Seoullo 7017 that transformed the overpass that was to be demolished into a "sky garden" using portable tree pots. Methods: Based on the summer season when the metabolic activity of plants is most active, this study measured the cambial electrical resistance in four directions(east, west, south and north), using the Shigometer (model OZ-93, Osmose) and compared the location and analysis of pots according to their means and standard errors. Results: Meanwhile, according to the analysis, vitality was relatively superior in pots with a big diameter, trees planted individually than in groups, trees of the ramp section rather than the bridge section, and in the southwest direction of the cambium. Conclusion: This study revealed the improper condition of the planting plan and implementation on the site, where various species of trees are displayed in a poor environment. Despite the significant assessment of the vitality of various trees introduced within Seoullo 7017 for the first time, this study is limited in that the data used were measured only once in summer. In this regard, it raised the need for continuous interest in and monitoring of a special plant environment and development of proper maintenance and management techniques, along with follow-up research on seasonal and temperature conditions, soil moisture and root development conditions to supplement this research.

Methods: Four types of classroom wall gardens were used in this program, such as the 'plaster pot wall garden', 'attachable LED wall garden'. 'coffee pack wall garden', and 'hanging wall garden' for each classroom. For this purpose, official letters were sent to relevant institutions (elementary schools) specified by the research institute, and classes were conducted on the selected elementary school students. Results: A satisfaction survey and effect analysis were conducted on the students participating in the program. The program was designed to take a total of 11 hours, comprised of teaching plans including the topics, purpose of production, subject outlines, learning goals, and elements of STEAM subjects and stages. Conclusion: According to the survey on student satisfaction and understanding, it was found that students participating in the program have a high level of understanding and participation, as well as increased interest in science. Also, the program helped the students to connect with other subject areas. The level of student satisfaction was especially high in the upper grades. It is believed that the results of this research contribute to the development of STEAM education programs in agriculture and life sciences as well as other subject areas.

In the development of automated driving, interest in the interior parts of vehicle is to become more significant in terms of the occupant safety and comfort. This study proposed an optimal design of front seat according to the design requirements for frame stiffness and seat comfort. For the seat comfort, the appropriate foam thickness was obtained using the structural analysis under reclined occupant loadings. While the strength and stiffness analyses were performed to evaluate the seat frame structure. Topology optimization was carried out based on the simulation results and the derived optimal model and baseline seat design was updated. The conceptual seat design for the autonomous vehicle in this study showed that the model development process is appropriate for the design parameters in both frame stiffness and seat comfort.

Korea's original traditional costume designs have a great potential to be re-imagined from a global perspective and developed into high-value-added fashion culture products that can enter the international market. This study applied the structural features of traditional clothing to the design of fashion cultural products. This study developed designs using Beja, Sagyusam, Aekjuem-po, Danlyeong, Cheolrik, Jang-jegori of Korea. To the best of our knowledge, this study is the first to conduct a literature survey of traditional Korean clothing. We designed shirts using Adobe Illustrator and created a pattern with the Yuka program. This design was applied to a three dimensional virtual dressing system called CLO. A survey of individual interest in developed fashion cultural products was also conducted. The shirt designs were obtained by applying the details and structural characteristics of traditional Korean clothing. Among the six shirt designs, when asked which design would be suitable for wearing, gifting, or uniform, the shirts with the design of Danlyeong, Beja, and Sagyusam were generally highly preferred. This study can be used as basic data for the global market for fashion cultural products, and can contribute to the inheritance and development of culture and tradition by maintaining Korea's uniqueness in the modern global era and increasing tourism revenue.
