Penetration of a fragment-like projectile into Fiber Reinforced Concrete (FRC) was simulated using finite element (FE) and particle formulations. Extreme deformations and failure of the material during the penetration event were modeled with multiple approaches to evaluate how well each represented the actual physics of the penetration process and compared to experimental data. A Fragment Simulating Projectile(FSP) normally impacting a flat, square plate of FRC was modeled using two target thicknesses to examine the different levels of damage. The thinner plate was perforated by the FSP, while the thicker plate captured the FSP and only allowed penetration part way through the thickness. Full three dimensional simulations were performed, so the capability was present for non-symmetric FRC behavior and possible projectile rotation in all directions. These calculations assessed the ability of the finite element and particle formulations to calculate penetration response while assessing criteria necessary to perform the computations. The numerical code EPIC contains the element and particle formulations, as well as the explicit methodology and constitutive models, needed to perform these simulations.

This study investigated the anthropometric characteristics of US women 26 to 45 years of age to classify their body shapes into different categories. Research data was obtained from 2950 women 26 to 45 years of age who participated in the SizeUSA study. A 26 to 35 years of age group and a 36 to 45 years of age group were selected from the data pool. A total of 26 measurements important for body shape classification and for apparel product development was used for the data analysis. Five factors accounted for the US women's body measurements. The body shapes of women were categorized into 4 types: Obese A-Shape, Overweight Y-Shape, Obese H-Shape, and Normal S-Shape. Normal S-Shape was the most common body shape type. More women in the 26 to 35 years of age group had Normal S-Shape type than women in the 36 to 45 years of age group. More women in the 36 to 45 years of age group had Obese A-Shape, Overweight Y-Shape, and Obese H-Shape than women in the 26 to 35 years of age group. Younger US women, 26 to 35 years of age had slimmer body sizes with more balanced body shapes; however, older US women, 36 to 45 years of age had larger body sizes with more various body shapes.

Internet apparel businesses are required to provide various kinds of consumer information which includes both product information and customer service information. "New Age Elderly" who become an aged man in 21th century are familiar with internet and other high technological tools from their life time experience with technological development and ready to enjoy the convenience the technology offers. As a preliminary step to develop internet consumer information model for elderly consumers, this study examines the US and Korea apparel e-tailing sites targeting elderly consumers. Ten Korean sites and nine US sites were selected and compared for their provision of consumer information in terms of contents, ease to access, and the completeness of the information. Results of data analysis indicate that elderly market in Korea is not yet clearly defined compared to the US. In Korea, elderly consumer market is considered as a part of middle-aged market, and there was no unique target marketing efforts observed. Korean sites are better than the US's sites in terms of shopping information, while the US sites offer detailed information about the company, and customer service information. In both countries, fashion related information is lacking and failing to satisfy fashion conscious elderly consumers. Managerial implications were discussed.

The arena of strategic competition between the US and China is expandable from international politics, trade and commerce to finance. What would happen if financial sanctions against China are imposed by the US? Would US financial sanctions lead to a sudden outflow of foreign capital and a liquidity crisis in China? We try to address these questions by estimating China's capital flows-at-risk with the CDS premium on Chinese sovereign funds. We follow Gelos et al. (2019) in setting up a quantile regression model from which China's foreign capital flow-at-risks are estimated. Based on our analysis of China's monthly capital flow data, we find that a rise in the CDS premium has statistically significant negative impacts on China's foreign capital flows-at-risk, mainly in banking flows. However, the analysis also found that due to favorable global conditions, an increase in the CDS premium is unlikely to trigger a shift to a sudden outflow of foreign capital at the moment. Meanwhile, this study found no statistically significant correlation between Korea's capital flows-at-risk and the CDS premium, suggesting that the negative impact of US financial sanctions on China would not increase the probability of capital flight from Korea in a significant manner.

Forty cross bred ($168\;{\pm}\;28\;kg$) bull calves were offered either untreated (US) or urea ammonia treated (TS) rice straw at five levels of feeding, namely; 60, 80, 100, 120 140% of ad libitum. Ad libitum level for each animal was estimated over a period of one month, which was followed by a preliminary period of 21 days and a collection period of 15 days. The maximum organic matter intake (OMI-kg/100 kg BW) were 2.08 and 3.35 for US and TS, respectively and urea treatment increased the maximum OMI by 61% than for US. In order to reach maximum intake the amount feed refusal should be 25% for US, but with TS maximum intake was not reached even when the amount of feed refused was 39% of that consumed. The OMD of US significantly decreased with increase in OMI, whereas with TS the decrease was not significant. The inability of animals to select between stems and leaves particularly in TS might be one of the reasons for its constant digestibility. Considering the substantial increases in intake and the negative effect on digestibility of US, further trials are warranted, as well as studies to determine the practical implications.

Healthcare is a research field suitable for applying the recent ubiquitous techniques. As a test system, we developed a kind of CDSS (Clinical Decision Support System) running in ubiquitous environment. called as 'uCDSS'. The uCDSS is a core system of the ubiquitous healthcare and is composed of some 'uMLMs(Ubiquitous Medical Logic Modules)'. The uMLMs based on the class in C# programming language could be reused in development of CDSS, or another EHR system running in .NET environment. As a test system, we developed the DM(Diabetes Mellitus knowledge system using ASP.NET. This system shows the potential of C# class-based uMLMs and the extensibility to any .NET development project.

The objective of this study was to explore the role of familiarity in cross-cultural product perception and perception changes according to food systems (hot sauce and spicy-chicken) in Korean and US consumers. Free choice profiling was conducted by Korean and US consumers on four spicy-chicken samples made using four hot sauce samples. Half of the hot sauce samples were selected to be more familiar to US consumers and vice versa to Korean consumers. A previous study that investigated cross-cultural perceptions of the same four hot sauce samples in US and Korean consumers was incorporated in this study. For distinct sample differences, US and Korean consumers perceived products similarly. However, for less obvious differences, flavor familiarity seemed to affect consumers' product perceptions. In addition, product perceptions changed more dramatically according to food systems for familiar samples in each country. The findings of this study show that consumers' product perception can be affected by flavor familiarities.
