For implementing this study, three agri-proccesing industries and other three counterpart industries which are located in Chungnam and Chungbuk provinces were selected based on the sizes such as large, medium and small scales. And then analyzing the direct income like wage incomes, indirect incomes derived from sales of the raw materials concerned and the derived incomes from consumer's expenditures were carried out by applying the income multiplier model based on the 6 industries sampled. According to the positive evaluation results on the agri-proccesing industries, it was verified that agri-proccesing industries have more influences on rural economy than other industries. Therefore the agri-proccesing industries have so greatly contributed to improving rural economy. On account of the above facts, the agri-proccesing industries have to be promoted and grown even though the management difficulties of the industries.

Since the designation of the South Korean Construction industry as an open market industry by the World Trade Organization (WTO) in 1994, South Korea's construction firms were exposed to competition from firms of other advanced countries. Increased competition in the industry raised quality of production and lowered the cost of construction projects. Therefore, many big construction projects were planned and constructed with foreign construction partners during the last decade. Also, from those projects the South Korea Construction industry accumulated experience in and knowledge of both project management and construction management perspectives. However, in the process of conducting those big projects, many problems - specifically responsibility and the limit of competence - occurred between foreign construction partners. Hence, this study attempts to improve its role model that is for local and foreign companies to enter into Joint Ventures in the South Korea construction industry.

Korea is showing its appearance as a leading country in the hydrogen economy by establishing policies for revitalizing the hydrogen economy and enacting the 「Hydrogen Economy Promotion and Hydrogen Safety Management Act」 for the first time in the world. In addition, domestic hydrogen facilities are using hydrogen energy safely through world-class safety management compared to overseas advanced countries. However, in order to enhance the safety of the rapidly diversifying hydrogen industry and rapid technology development, such as the introduction of liquefied hydrogen, some institutional improvements are needed. In this regard, this paper intends to analyze the results of safety inspections on 13 representative facilities and prepare safety improvement plans to establish preemptive safety measures.

This paper deals with studying strategy about impact of deep learning (DL) on the factor of Korean economic growth. To study classification of impact factors of Korean economic growth, we suggest dynamic equation of microeconomy and study methods on economic growth impact of deep learning. Next step is to suggest DL model to dynamic equation with Korean economy data with growth related factors to classify what factor is import and dominant factors to build policy and education. DL gives an influence in many areas because it can be implemented with ease as just normal editing works and speak including code development by using huge data. Currently, young generations will take a big impact on their job selection because generative AI can do well as much as humans can do it everywhere. Therefore, policy and education methods should be rearranged as new paradigm. However, government and officers do not understand well how it is serious in policy and education. This paper provides method of policy and education for AI education including generative AI through analysing many papers and reports, and experience.

Currently, there is a drain of natural resources, environmental contamination, generation of waste, and problems of the earth's climate by CO₂ emissions according to mass production and overconsumption of mankind. It is effectuated by a linear economy that involves manufacturing products, use, and waste repeatedly; there is no guarantee in the lives of humans and the future of the globe if we do not find alternative proposals. For a sustainable developing society and to overcome the present global problems, we must successively change to a circular economy from a linear economy. The circular economy has the concept of an extended value chain in recovery, reuse, remanufacturing, and recycling, instead of discarding after the use of manufactured goods. New business models of circular economy have been realized to save the earth ecology and sustainable developing society in serious recognition of the linear economy system. New business models are established by creating a vision and developing a program, and by renovating technology, law, and financial support through a worldwide government policy.

Recently, not only common types of hybrid electric vehicle (HEV) such as series or parallel but many other types of HEVs including 4WD hybrid electric vehicle have been developed and released. In this study, analysis of fuel economy and driving performance for 2WD and 4WD HEV are conducted using backward simulation based on dynamic programming. To analyze the characteristics of 4WD HEV, tire slip model based on vehicle dynamics was applied to the backward simulation program. As a result, 2WD HEV shows better fuel economy than 4WD HEV because of relatively simple configuration. However, in a severe road condition, 4WD HEV shows better driving performance that 2WD HEV had about 6% of impossible time to follow the driving cycle though the 4WD HEV had no impossible time.

Population growth and increasing consumption of resources in the process of the industrial development has caused environmental pollution, climate change, and resource exhaustion. Therefore 'sustainable development' has become the important issue for the future. The sustainable development aims at effective resource use, less environmental impacts, and higher social security. Generally the rural area including agricultural fields and forest has various and plentiful natural resources which could make future development sustainable. To develop potential rural resources, the values for energy, environment and economy should be assessed considering the life-cycle of resources. The purposes of this study are to suggest the E3 (Energy, Environment, and Economy) assessment model for rural biomass considering life-cycle of resource and to apply the model to rice, the major agricultural product. As the results of this study, it turned out through E3 assessment that economic gain of rice cultivation is 578,374 won/10a, carbon absorption is $1,530kgCO_2/10a$, carbon emission is $926.65kgCO_2/10a$, and bio-energy potential of by-product is 394,028 kcal/10a. When E3 assessment was applied to by province, the results varied by regions because of the amount of input during cultivation. These results would be useful to realize the rural biomass and design regional resources plan in integrated E3 perspective.

This study analyzes the effect of fiscal decentralization on economic growth by using each province city's panel data of China from 1985 to 2008. By using Recently developed fiscal decentralization index and autonomy of local government quantified this study finds the following conclusions. The increase of inflation rate affects positive effect on Chinese economy. This is the trade-off relationship with the growth of Chinese economy by the Phillips Curve theory. So this suggests the instability of Chinese economy. The affiliation of WTO of China shows positive effect on Chinese economy. This can be translated as the real evidence about free trade theory of Classical School. Expenditure decentralization in China led to economic growth and revenue decentralization also affected positively although it was not as much as expenditure decentralization's effect. Central tax and local tax negatively influenced economic growth; and differently from our expectation, local government autonomy quantified was not relevant to economic growth.

Purpose Recently, the tours and activities (TAA) market provided by online travel agencies (OTA) has grown rapidly and has become the third-largest in the travel industry. However, compared to its practical proliferation, TAA has not yet received much academic attention. This study aims to discuss the effect of the four domains (e.g., educational, entertainment, escapist, and esthetic experiences) of the experience economy on users' memorable tourism experiences (MTE), satisfaction, and loyalty in the context of TAA. Moreover, the study investigates how this mechanism varies depending on the tour guides' professional competency. Design/methodology/approach This study developed a research model based on the S-O-R framework. Using the survey method, data were collected from consumers who had experienced TAA offered by OTA more than once within one year. A total of 307 respondents (consumers) were used for the final analysis, and developed hypotheses were tested using a structural equation model technique. Findings The results of this study are as follows. First, educational, entertainment, and escapism experiences in the experience economy positively affect MTE. Second, within the experience economy, entertainment and esthetic experiences have a positive effect on satisfaction. Third, MTE positively influences satisfaction, repurchase intention, and recommendation intention. Fourth, satisfaction has a positive impact on repurchase and recommendation intentions. Finally, according to the level of tour guides' professional competency, there is a significant difference in the effect of escapism experience on MTE/satisfaction.
