This study attempts to examine the economic impacts of electricity industry in Korea and Japan using an inter-industry analysis. Specifically, the study analyzes and compares electricity industry between Japan and Korea through production-inducing effect and value added inducing effect of electricity industry based on demand-driven model. Moreover, this study deals with supply shortage effect and sectoral price effect by using supply-driven model and Leontief price model, respectively. This study analyses the electricity industry through exogenous approach. The results show that electricity industry induces prodution-inducing effect of 0.5946 won in other industries in Korea and 0.5446 yen in other industries in Japan. Value-added-inducing effects are 0.1716 won in other in other industries in Korea and 0.2929 yen in other industries in Japan. Supply shortage effects of electricity industry are 1.5932 won in other industries in Korea and 1.2801 yen in other industries in Japan. And sectoral price effects are 0.2113% in Korea and 0.2196% in Japan due to the price increase of 10% of electricity industry.

The government is planning to expand the bio-gas supply as a method for mitigating greenhouse gas emissions to deal with climate change. By means of a policy instrument, the government is considering an introduction of the Renewable Fuel Standard (RFS) whose targets include bio-gas. This paper attempts to look into the economic effects of expanding the bio-gas supply by applying an input-output (I-O) analysis using a 2011 I-O table. The bio-gas supply sector consists of liquefied petroleum gas supply sector and city gas supply sector, based on the tenets of introducing the RFS. The production-inducing effect, value-added creation effect, and employment-inducing effect of the bio-gas sector are analyzed. The supply shortage effect and the price pervasive effect are also investigated. The results show that the production or investment of 1.0 won in the bio-gas supply sector induces the production of 1.0539 won and the value-added of 0.1998 won in the national economy. Moreover, the production or investment of 1.0 billion won, supply shortage of 1.0 won, and a price increase of 10.0% in the bio-gas supply sector touch off the employment of 0.5279 person, 1.6229 won, and an increase in overall price level by 0.0183%, respectively.

As open skies polices have permeated all over the world, Korea's basic direction of aviation policy is promoting the benefit of the public and the national carriers' competitive power by establishing open skies agreements between the countries. The open skies' directions should be promoted by considering the relationships of various attributes such as governments, airlines, and passengers. To decide the right directions of open skies, we should investigate the economic effects of open skies policies. This research develops a simulation model to analyze the dynamic characteristics of open skies. By using the developed model, this research analyzes the economic effects of open skies. The results showed that open skies have direct impacts on not only frequencies, airfare, consumer welfare but also air transport industry and regional economy. Therefore, it is necessary to take suitable aviation policy that can increase the effects of open skies.

There is a need to have a dredging index for decision of contaminated sediments dredging. Some differences from nation to nation were found in sediment quality guideline being applied by several nations because of economic level, environmental nature, and multiple uses. Therefore, it is not reasonable to adapt one guideline to be applied to sediments dredging. In this study, we developed dredging index by combining four numerical sets of sediment quality judgement into a quadrodiagram for prudential decisions. This newly developed dredging index was applied to the data obtained from Masan Bay before and after the dredging process. The quadrodiagrams of DI give us a nice graphical comparison and numerical values to explain the relative dredging effect under the circumstances of continuous input loadings. When the guideline value of DI is determined for the judgement of dredging considering social and economic impacts on local community, the DI value will be a scientific and reasonable tool in deciding dredging area and dredging depth.

This study analyzes the impact on continuous use of railroad logistics by mediating the logistics performance of recognition on the logistics service quality. According to the results, economic quality, information quality and relationship quality have impacts on the intent of continuous use by fully mediating logistics performance. Based on these results, a model for intent of continuous use of railroad logistics was proposed. As for the results of this study, it can be seen that the continuous use of railroad logistics is formed by the logistics performance due to the use of railroad logistics and, for this, a practical direction is suggested: the improvement of service is required, by which the recognition can be enhanced for the economic quality, information quality and relationship quality of the customers.

Korea and China should come up with a mutually beneficial FTA proposal at an early date and thus lead the way towards the FTA. An FTA with China is a key issue of economic cooperation in order to confront soaring Chinese competitiveness in international markets. The purpose of this research paper is to analyze the overall Busan regional economy impacts of the Korea-China FTA. We analyzed the quantitative effects of an FTA by using microeconomic concept. The Korea-China FTA will have positive effects on the overall industry in Busan. Therefore, Busan regional industries exports and imports are expected to grow. Busan is worried the deal would pave the way for imports of cheap Chinese agricultural products, hurting the nation's already fragile agricultural sector. In contrast, Busan's manufacturing sector is expected to see its surplus rise. In sum, we think the FTA will bring benefit to the whole industry in Busan Regional economy because it accelerates development of the industries by trade and investment along with comparative advantage.

Rural tourism has been identified as providing opportunities to revitalize the rural economies since early 2000s. During last decade in South Korea, government has enacted many policies aiming to establish tourism support programs as well as instigating activities between rural and nearby urban districts. In particular, the promotion of the rural tourism has been actively sought in various forms of products and services, such as green tourism village, village festival, one-company one-village campaign and etc. However, in order to prepare effective policies, it is very crucial to identify measureable evaluation criteria that can be used to assess socio-economic situations of the rural districts. Such criteria should be objective, timely and provide insights about living conditions of local residents and relevant properties. They can also be used to evaluate if progress is being made after the policies are implemented. While considerable efforts and resources have been invested to aid the tourism programs in South Korea, we still lack such systematic means to quantify and evaluate its impact on rural districts. In this work, we have applied regional deprivation analysis on well-established community experiential and recreational business in rural villages throughout the country based on three criteria (i.e., population, local commerce, and buildings). Surprisingly, the result shows that the implementation of the community experiential and recreational businesses did not bring any noticeable changes to at least one of the evaluation criteria. We concluded that the current government policies on revitalization of rural tourism at the village scale is insufficient for bringing meaningful socio-economic impacts to rural districts, with rare exceptions.

A growing number of fashion brands and retailers are actively adopting live streaming as a new marketing channel. In spite of the increasing use of live commerce, the effects of live streaming commerce on customer purchasing behavior for fashion products are not fully understood. The purpose of this study is to examine factors affecting consumers' attitudes toward a purchase via fashion live streaming commerce (FLSC) and intention to use FLSC. The study also investigated whether consumers' expenditure on fashion and time spent on mobile shopping moderate the relationships among research variables. A total of 230 questionnaires were analyzed through descriptive statistics, confirmatory factor analysis, and multiple-group comparison tests using SPSS and AMOS. A summary of the main results of this study is as follows. First, the perception of the attributes of FLSC (ease of use, economic efficiency, interactivity, and enjoyment) has a positive effect on attitude toward a purchase via FLSC. The ease of use and economic efficiency of FLSC, in particular, have greater impacts on attitudes than other factors. Secondly, attitudes toward FLSC positively impact the intention to use FLSC. Lastly, the results of group comparisons, by fashion expenditure and time spent on mobile shopping respectively, hold no significant moderation effects among the variables. These findings demonstrate that consumers are more likely to use FLSC as they form a positive attitude by the attributes of FLSC mentioned earlier. The study provides some insights on an exploration of live streaming commerce for fashion product sales.

The purpose of this study is to examine the impact of callous-unemotional traits(CU) on juvenile crime and explore additional effects of parenting and socioeconomic status on juvenile crime. A total of 103 juvenile probationers completed self-report questionnaires at 3 probation offices in Seoul, and a total of 123 high school students completed self-report questionnaires in Seoul and Gyeonggi. The results of this study were as follows. First, juvenile crime group showed higher score in uncaring subscale of CU, lower parent's education and lower economic level than normal group. Second, in both groups, uncaring subscale of CU showed negative correlations with parent's acceptance and daily monitoring. Third, in logistic regression, uncaring subscale of CU and low economic level significantly predicted juvenile crime group. This study suggests that uncaring characteristic of CU and socioeconomic status are potential factors contributing to juvenile crime.

This study is to investigate the effect of environmental mitigation in relation to the construction of quay structures for containers and to estimate economic values of environment-friendly structures using CVM. The result shows that the B/C ratio of environment-friendly quay structures designed to mitigate environmental impact is 4. That is, environmental improvement work proves to generate environmental benefit over 4 times as much as the construction cost. Considering the results of the study, environmental improvement work is of great benefit to citizens, and CVM is expected to become an efficient method to measure a proper size for a large construction project as well as to forge public consensus.
