This study aims to investigate the determinants that can influence customer satisfaction and loyalty. Compared to some of the determinants that have been investigated by other scholars before, this study also includes a new approach to mobile food-ordering that has only appeared within the Chinese fast-food industry in recent years. It is very important to test if the convenience of mobile ordering services can influence customer satisfaction, as more and more customers are using mobile apps to order food, especially in the 4th Industrial Revolution Era. Research data mostly was collected from customers who visited one of five famous Western fast-food restaurants (KFC, McDonald's, Pizza Hut, Subway, and Burger King) in China. The results show that not only price, service quality, food quality, and the physical environment can significantly affect customer satisfaction but also the convenience of mobile ordering services, a new determinant accompanied by the fast development of IoT technology.

China adopts the "Outline of the 14th Five-Year Plan for National Economic and Social Development of the People's Republic of China and the Long-Range Objectives Through the Year 2035" in the context of tremendous changes in the international environment. A new development paradigm is proposed to prioritize domestic circulation, reinforcing both domestic and international circulations. The industrial policies of China's "14th Five-Year Plan" will have an impact on Korea. Thus it is necessary for Korea to cooperate with China to actively respond to changes in the industrial chains and value chains in Asia and the world. Over the past 29 years since the establishment of diplomatic relation between China and South Korea, the two countries have enjoyed close economic and trade relations. China-ROK cooperation is critical to regional economic development in the Fourth Industrial Revolution and the era of remarkable changes in the world's political and economic structure. China is a robust developing country, while Korea is a developed one in with steady foothold in the world economy. China and South Korea should work together to contribute to the rapid recovery and development of the world economy instead of becoming competitors.

In the midst of the progress of the 4th industrial revolution, the Corona19 Pandemic was forming giant double wave. Companies riding this wave can win, but companies that do not will fall into the wave and struggle. In connection with the 4th industrial revolution, various technologies are emerging and commercialized. At this point, consumers, especially digital natives, who have been with digital since birth, tried to find out what factors affect the intention to use these technologies and which factors have the most important influence. For this purpose, data were collected through a survey on factors affecting the intention to use FinTech technology and AR technology for 150 digital natives in their 20s. Based on this, statistical analysis was conducted and the following results were obtained. As a result of the overall analysis regardless of the type of technology, it was found that performance expectancy, effort expectancy, social influence, and habits have a positive (+) effect on digital natives' intention to use the 4th industrial technology. On the other hand, a significant influence relationship between the facilitating conditions, hedonic motivation and intention to use the 4th industrial technology was not tested. It was found that the influence was greatly influenced by social influence and habits. In the case of FinTech and AR, which were further subdivided into this study, different aspects were revealed as a result of separate analysis. In the case of FinTech technology that emphasizes utilitarian value, performance expectancy, effort expectancy, social influence, and habits had a positive (+) effect on intention to use. It was found that the influence was greatly influenced by habits and social influence. In the case of AR, which emphasizes the hedonic value, all the variables adopted in this study had a positive (+) effect on the intention to use the technology. It was found that hedonic motivation and social influence had a great influence. Combining the results of the analysis, social influence was found to be an important influence variable regardless of the type of 4th industrial technology. FinTech technologies such as mobile banking, where services are becoming more common, are habits, and in the case of AR, which has not yet been universalized and is provided mainly for entertainment, hedonic motivation was found to be an important factor. This study was able to present academic and practical implications based on the above confirmation of factors affecting digital natives' acceptance and use of the 4th industry technology.

Dietary powder from Plantaginis ovatae testa was prepared by mechnical milling/grinding of the outer layer of the seed. The crystalline/surface structures of its powder (100 mesh) were examined, and several physical functionalities including, water capacity, oil holding capacity, emulsion/foam properties and physiological functionality such as in-vitro glucose and bile acid retarding effects were also investigated. Water holding capacity(WHC) of psyllium powder was $33.71{\pm}0.10g$ water retained/g solid at room temperature, whileas oil holding capacity(OHC) for soybean or rice bran oil were about 1.80g oil retained/g solid. These values of WHC and OHC were about 5.6 times higher and 2.8 times lower than those of commercial ${\alpha}$-cellulose, respectively. Changes of pH showed a small effect on WHC, but WHC increased with temperature. Emulsion capacity of 2%(w/v) psyllium was about 60% level of 0.5%(w/v) xanthan gum but emulsion stability after incubation of 24 hours showed about 1.4 times improvement of xanthan gum(0.5%,w/v). Also, psylliume(above 2%, w/v) alone had higher foam capacity than that of xanthan(1.1 times) and especially, 1 or 2% addition of psyllium improved the foam stability of protein solution(1% albumin+0.5% $CaCl_2$) by factor of 3.3 and 6.0 times, respectively. The glucose and bile acid retarding effects of psyllium powder were relatively very excellent suggesting the prevention from diabetes and arteriosclerosis. Especially, psyllium showed the 3.7 and 3.3 times higher effect on in-vitro glucose and bile acid retardation than those of commercial ${\alpha}$-cellulose, respectively.

Opening of a new economic paradigm in the transition to the Fourth Industrial Revolution, the human capital engaged in industry or occupation based on individual creativity is called creative workers. The workers of this kind regards 'quality of place', known as amenity, as an important factor in choosing a residential area. This paper analyzes how the effect of city amenity influences on residential preference of creative workers in comparison with production workers. First, as of 2014, the total number of creative workers are 5.73 million (23.2% of the total workforce), and more than half (58.6%) are concentrated in Seoul and Gyeonggi area. Second, the excess residence rate of the creative workers (number of residents/number of jobs) is high in metropolitan areas. Third, when comparing with workers in productions sector, the selection of residence location for creative workers are significantly influenced by certain city amenities such as education. The outcome of analysis is expect to be utilized as a preliminary work for making policies which promotes number of creative workers at the regional level.
