Purpose - The digital service trade has become an important driver of the global service trade. The main purpose of this study is to explore the influencing factors of digital service exports from China and Korea to RCEP sample countries respectively, and to comprehensively study the export potential of China and Korea to RCEP countries, so as to provide theoretical guidance and a decision-making reference to promote digital service trade exports and digital economy development in China and Korea. Design/methodology - First, the stochastic frontier gravity model was improved by introducing nonefficiency factors affecting digital services trade, extending the gravity model of traditional services trade exports to digital services trade exports. Secondly, the panel data of China and Korea for the eight sample countries of RCEP from 2011 to 2021 were adopted for the empirical analysis of digital service export potential by a stochastic frontier model. Findings - China's economic growth plays a role in increasing China's digital service trade exports, while Korea's economic growth does not play a significant role in increasing Korea's digital service trade exports. However, the economic growth of trading partner countries can play a significant role in boosting the digital service trade in both China and Korea, and comparison shows that Korea has higher resilience in the digital services trade than China. In addition, the market size of target countries plays a positive role in promoting the digital service trade exports of both China and Korea, and the increase in the value-added share of services in target countries will lead to a decrease in the digital service trade exports of both China and Korea. Originality/value - This study is innovative in terms of research perspective and method. Academic research on the export potential of international trade has been extensive, but most studies are based on the perspective of the goods trade, fewer studies are based on the perspective of the service trade, and there are almost no studies based on the perspective of digital service trade. There is a gap based on the comparative analysis of the export potential of the digital service trade between China and Korea. This study extends the gravitational model of traditional service trade exports to digital service trade exports to comparatively analyze the export potential of China and Korea to RCEP countries. This study addresses this limitation by analyzing a comparative analysis of the digital service trade export potential of China and Korea.

The Korean textile industry the driving force of Korea's economic development, is faced with difficulties due to domestic and foreign influences. The purpose of this paper is to examine what measures are necessary for overcoming such difficulties. As the first step, We conducted a month-long survey, in August 2003, of 157 small-medium firms operating in the Korean textile industry to collect information about difficulties that they face in carrying out their business. According to the result, small firms performed badly in sales and facility investment efforts for 2003 due to worldwide economic depression. They, however, actively pursued new technology development in order to improve their competitiveness. Profits and productivity decreased with reduced sales, and their view on the next year’s perspective is also very unfavorable. Especially many firms intend to maintain or even lower the level of sales goal for 2004, reflecting the sluggish market environment. According to the survey, under such circumstances, as many as 74% of firms wanted to turn the tables through the development of highly sensuous material and improved marketing efforts. One of potential answers to this problem, which is suggested by the survey, is to establish a consulting service institution to provide promptly marketing data and information on textile and fashion market and trend in Italy. Especially, firms surveyed have shown a great deal of interest in Italian consulting service for new textile material developments. While they want the service for high value-added product development, they are reluctant to do so because of the uncertainty of its future effects and high consulting fees.

In recent years, building commissioning has often been part of a standard delivery practice in construction, particularly in the high-performance green building market, to ensure the building is designed and constructed per owner's requirements. Commissioning, therefore, intends to provide quality assurance that buildings perform as intended by the design and often helps achieve energy savings. Commissioning, however, is not as widely adopted as its potential benefits are perceived. Owners are still skeptical of the cost-effectiveness claims by energy management and commissioning professionals. One of the issues in the current commissioning practice is that not every project is guaranteed to benefit from the commissioning services. This, coupled with its added cost, the commissioning service is not acquired with great acceptance and confidence by building owners. To overcome this issue, this paper presents a unique methodology to enhance owner's predicting capability of the degree of success of commissioning service using the Bayesian theorem. The paper analyzes a situation where a future building owner wants to use a pre-commissioning in an attempt to refine the success rate of the future commissioned building performance. The author proposes the Bayesian theorem based framework to improve the current commissioning practice where building owners are not given accurate information how much successful their projects are going to be in terms of energy savings from the commissioning service. What should be provided to the building owners who consider their buildings to be commissioned is that they need some indicators how likely their projects benefit from the commissioning process. Based on this, the owners can make better informed decisions whether or not they acquire a commissioning service.

This study investigated the quality characteristics of muffins containing Actinidia polygama powder, which is well known for its various functions and biological activity. With increasing Actinidia polygama powder, the volume, height and specific volume increased significantly. The height of the muffins prepared with Actinidia polygama powder was higher than that of the control group. The pH of the muffin decreased significantly with increased levels of Actinidia polygama powder. The moisture of samples raged from 26.83% to 30.86%. The L- and b-value decreased, while a-value increased, with increasing amounts of added Actinidia polygama powder. Textural profile analysis showed that the hardness, springiness and chewiness were decreased with increasing Actinidia polygama powder contents. As the Actinidia polygama powder content increased, 1,1-diphenyl-2picriylhydrazyl(DPPH) radical scavenging also significantly increased. The sensory evaluation results indicated that the group of 3% Actinidia polygama powder recorded the highest overall preference score at 6.20. The quality characteristics of the 3% added samples exhibited significantly similar or higher values as compared to those of the conrols, raising the possibility of development in health-functional muffins.

This study was to investigate the effect of the addition of red ginseng powder in Dasik. The addition of red ginseng powder in Dasik that we used with was in the ratio of 0%, 2%, 4%, 6% and 8% of red ginseng powder to Dasik in weight. Also, we used two different kinds of Dasik. One was made of starch and the other was made of flour. The physic-chemical analysis and sensory test were performed on the Dasik. The red ginseng powder added flour and starch Dasik showed lower moisture content and higher ash content compared with the non-added control group. In color analysis, whereas L value lowed at the addition of red ginseng powder, a and b value increased at the addition of red ginseng powder. In mechanical texture test, addition of red ginseng powder starch Dasik showed high hardness, cohesiveness and brittleness. Addition of red ginseng powder flour Dasik showed high springiness and gumminess. In the sensory test, the addition of the red ginseng powder reduced the sweetness and increased the surface color and the flavor. There was no difference in preference between the Dasik with up to 4% of red ginseng powder added and the control group, but the Dasik with 6% or more red ginseng was found undesirable (p<0.05). In conclusion, the Dasik with up to 4% addition of red ginseng powder would be the useful method to fulfill the traditional quality of Dasik. It was also found that the flour Dasik was to be more preferable than the starch Dasik.

This study was conducted to examine the physicochemical and sensory characteristics of Bulgogi seasoning sauce added with Angelica gigas Nakai extract and salted liquid of Prunus mume. Increasing the amount of salted liquid of Prunus mume in the Bulgogi sauce added with Angelica gigas Nakai extract made its pH and brix decreased. And the lightness(L) value of the samples ranged from 22.50 to 23.43, and the redness(a) and yellowness(b) increased. For the textural characteristics of Bulgogi meat, the addition of salted liquid of Prunus mume decreased its hardness. In the sensory evaluation, Bulgogi added with 10% of salted liquid of Prunus mume made excellent scores in texture, taste and overall preference. Therefore, this results suggest that 10% of salted liquid of Prunus mume and Angelica gigas Nakai extract should be applied to Bulgogi sauce in order to satisfy its preference and functionality. For the changes of total viable cells of Bulgogi seasoning sauce by the storage period, increased amount of salted liquid of Prunus mume showed their number lower than that of the control.

Countries around the world are preparing policies to promote service economy. Recently, as the fourth industrial revolution is accelerating, interest in the service industry is increasing. Korea's service industry is among the lowest among OECD countries in terms of employment, value-added and productivity, and it is time to explore new development strategies. The Korean government is establishing a service economic development strategy to promote employment and economic vitality. However, in the era of the 4th industrial revolution, the service industry is very important in that it has to be fused with the manufacturing industry. This study examines the service industry policy related to the 4th industrial revolution which the central government, local governments, and countries around the world are pursuing through literature review. The Big data analysis is used to determine the interest rate of the seven major service industries and core technologies for the fourth generation industrial revolution.
