Chemical composition and contents of carbohydrates, lignin, and extractives in Moso(Phyllostachys pubescens Mazel), Henon(Phyllostachys nigra var. henonis Stapf ex. Rendle), and Timber bamboo(Phyllostachys bambusoides Sieb. et Zucc.) known as economically valuable bamboo species in Korea were analyzed as a function of ages. All of tested bamboo species were composed of fucose, arabinose, rhamnose, galactose, glucose, xylose, and mannose. Glucose was the sugar which showed the highest content followed by xylose. The contents of others were below 3%. Sugar contents of bamboo shoots showed the lowest among the tested bamboo samples, and the constant rates were shown after 50 days of growth. Lignin content increased by the growth of one year, and the increasing rates tended to be constant after the growth of three years. Bamboo shoots have the highest contents of acid-soluble lignin, which turned into insoluble lignin after the growth of 50 days. Bamboo shoots showed the highest content of extractives and tend to be decreased by the growth of 50 days and then the content increased slowly in proportion to the period of bamboo growth. No relationship was found between species and chemical composition of bamboo. However, there were significant difference in chemical composition between bamboo shoots and 50-day old bamboo.

Purpose: This study was conducted to optimize the conditions of manufacturing the wet noodle added with Aloe powder. Methods: The I-optimal design of response surface methodology (RSM) was used for the optimization of added amount of Aloe powder, water content, and kneading time as the independent variables. The quality characteristics (color, texture, water absorption ratio, volume, turbidity) and sensory characteristics (color, flavor, taste, mouth feel, overall acceptance) were analyzed as dependent variables. Results: The lightness, redness, and yellowness of the Aloe noodle were all lowered with the addition of Aloe powder. All texture characteristics such as hardness, elasticity and chewiness of Aloe noodle showed the tendency to increase with increasing amount of Aloe added and kneading time. The water uptake and the volume expansion tended to increase with increasing aloe addition and water addition. As the kneading time increased, the dissolution of solids decreased and the turbidity tended to decrease. Aloe powder content influenced the color, flavor and taste of the noodles most among independent variables, and the mouthfeel of the noodle influenced by the water addition and the kneading time. Conclusion: Aloe noodle showed the best desirability with 3.03% of Aloe powder, 43.56% of water content and 13.06 min of kneading time by RSM analysis. Aloe noodles prepared under these optimized conditions are expected to be able to manufacture and utilize functional Aloe noodles by meeting the content of isobarbaloin, which helps the intestinal functional activity.

Proximate and fatty acid compositions in muscle tissue were studied in 14 species of coastal and offshore fishes in Korea. Lipid content ranged from 0.57 to 10.5% and was higher in migratory and reef dwelling fishes than in demersal fishes. Protein content ranged from 14.4 to 20.3% and moisture content ranged from 72.4 to 81.8% in all fish samples. There was a negative correlation between lipid and moisture content in all fish samples (r= -0.90, P<0.001). The prominent fatty acids were 16:0, 22:6n-3 (docosahexaenoic acid, DHA), 18:1n-9, 20:5n-3 (eicosapentaenoic acid, EPA), 16:1n-7, 18:0 and 18:1n-7. Most demersal fishes contained considerably higher amounts of 20:4n-6 and/or 22:5n-3 compared with migratory and reef dwelling fishes. The proportion of total polyunsaturated fatty acid (PUFA), including DHA and EPA, was higher in demersal fishes (38.6-54.0%) than in migratory and reef dwelling fishes (23.5-35.2%).

With the emergence of digitalization and environmental changes, such as those caused by COVID-19 and high-speed networks, online video platforms have changed how people communicate and created new marketing opportunities. The unique characteristics of mobile short-form videos are causing more people to consume and produce diverse content in the digital environment. The study focuses on two story types (product essential and relative information) to examine the effectiveness of short-form videos for fashion marketing. This study verified the influence of the common traits of short-form video content (informativeness, expertise, familiarity, and playfulness) on fun, e-WOM, and purchase intention and the mediation effect of fun using video samples categorized by story type. In this study, 300 Gen Z men and women responded to a survey after watching a 30-second short-form video sample. All the traits of short-form video content were found to have a positive effect on fun. Moreover, all the traits excluding playfulness had a positive effect on e-WOM and purchase intention as well. Fun had a positive effect on both e-WOM and purchase intention as well as a partial mediating effect. These findings are expected to provide insight and reference for planning short-form video marketing from the perspective of the fashion industry.

Recently in the domestic construction industry, source depletion has resulted in instances of ready-mixed concrete companies using river sand or crushed sand with high fine particle content. But the use of such low-quality fine aggregate is known to cause concrete quality to decline and have negative effects. So this study analyzed how much of an impact changes in fine particle content have on cement mortar's engineering characteristics. As a result, the flow rate and air quantity, which are characteristics of unhardened mortar, were shown to decrease as fine particle content increased, and compression strength, a characteristic of light mortar, was shown to subtly increase as fine particle content decreased.

Enterprise Content Integration (ECI)is an IT strategy that improves enterprise' competitive advantages by integrating enterprise wide information and content into a unified view, which in turn supports efficient and effective decision making. Content Syndication Systems (CSS) is a solution that implements the ECI strategy. In semi-conductor industries, it is usual that enterprise content is scattered over tens of legacy systems. Therefore, engineers in semi-conductor companies spend a few hours to locate required engineering information on a daily basis as part of their jobs. In this paper, we develop an enterprise CSS system that integrates enterprise wide contents into a unified view that is suitable for semi-conductor industries. For this research, we first define enterprise CSS, then identify their systems requirements. Then we propose an architecture supporting the identified requirements, and present the implemented prototype. One of the most important requirements is the individualized subscription rule setting for engineering information. For this purpose, we developed methods to represent the information properties and subscription rules.

This study identifies and evaluates inter-ministerial coordination for developing digital content technology in Korea and Japan. It is conducted through a comparative analysis between Korean and Japanese governmental organizations and their decision making process. Media content had been regulated or promoted by ministries involving culture in both countries. The digitalization of traditional media, however, blurred boundaries between the cultural, technological, and industrial spheres, so ministries involving science and technology, economy and trade, or foreign affairs started to promote digital content technology in the late 1990s. This has been the cause of conflicts among ministries and sometimes led to policy duplication, which in turn weakens policy effectiveness. The competition and coordination of ministries and agencies can be seen through establishing or amending related laws, organizations, and programs. Structural holes are founded in the networks drawn among governmental agencies in charge of digital content, particularly in the field of intellectual property in Korea and online distribution technology in Japan.
