The relationship between market structure and social welfare outcomes has received considerable critical attention in the field of competition policy research. In particular, it is necessary to study in greater depth the impact of market power on social welfare in the telecommunications industry, which is highly likely to form a monopolistic market structure. This is because, when market powers are concentrated on few upper carriers, there are negative effects on social welfare due to an excess of profits. Against this background, the present study investigates the relationship between the market structure of the mobile communications industry (the level of market power) and social welfare outcomes (the retail rate cut) through an international comparison. The results demonstrate that both the market structure and competition status of the Korean market have had significant gaps in global trends. It also points out that the monopolistic market structure (when the leading provider has more than 50% of the market share) has significantly negative effects on consumer welfare (the retail price cut). In addition, the findings of this study suggest that the direction of competition policy should focus on not only improving market concentration(HHI), but also on mitigating the monopoly of power of a dominant operator.

In recent years, consumers emphasize the various sensory experiences in the process of shopping rather than the practical value of shopping results. In order to satisfy consumers' diverse needs, retailers transform their offline stores into experiential spaces to encourage consumers to experience diverse and enjoyable experiences. This study divided the sub-factors of customer experience into hedonic experiences, functional experiences, and social interaction experiences, and investigated the effect of sub - factors of customer experience on consumers' enjoyment and intention to stay in off-line store. In addition, it is assumed that there will be a difference in the influence of three levels of customer experience on enjoyment according to the consumer's self-construal levels. As a result of this study, all of the hypotheses were supported except hypothesis 1 that the customer's hedonic experience has a positive effect on pleasure. In addition, as a result of verifying the moderating effect of self-construal levels, the self-construal level of consumers has no significant effect on the path of hedonic experiences on pleasure, but significant moderating effects of self-construal levels were identified in the pathways of functional and social interactive experiences on pleasure. The results of this study will be helpful in identifying and utilizing differentiated experience marketing strategies in the off-line stores that only offline channels can have in the fierce competition due to the diversification of distribution channels.

This study aims to examine eligibilities, services and delivery of services for the current end-of-life care and analyze the quality control of services for end-of-life care. We analyzed the literature and laws on end-of-life systems in Korean and the United States. Current end-of-life care, hospice and palliative care in Korea is being provided mainly in hospital setting. Quality control for the services focuses on setting the criteria for structures in hospitals (i.e. staffing, facilities and equipment). Whereas American end-of-life care system has much broader eligibility for service beneficiaries and provides care mostly at home. Also quality control for services includes process (delivering service) and outcomes, such as monitoring performance indicators and consumer's satisfaction. This is linked to annual payment. The comparative analysis findings contributed to give the next direction of current Korean end-of-life care system. It is nessary to establish the better and extensive end-of-life care system in Korea in considering other countries' end-of-life care systems based on more future research.

O2O services, a form of mobile commerce, are increasing due to the widespread use of smartphones and the rational consumption trend of young consumers. In addition, the introduction of Social Commerce's O2O service has transformed customer experience into innovation. Therefore, the purpose of this study is to investigate the effect of O2O service characteristics and social commerce provider characteristics on the social commerce 's O2O service as a social psychological image that consumers have at the point of purchase and use time, as a smart shopper feeling and a cheapness shopper feeling. And the relationship between consumer satisfaction and intention to use through Structure Equation Modeling, and to suggest the implications for O2O service management that can provide greater satisfaction to consumers by identifying the process of creating satisfaction of O2O service. The results of the study show that price discounts and scarcity of social commerce's O2O service characteristics have shown that it increases smart shopper feeling. Also, it was confirmed that brand awareness and ease of purchase, which are characteristics of social commerce, confirms the increase of cheapness shopper feeling. We also confirmed the effect of smart shopper feeling and cheapness shopper feeling on satisfaction. This satisfaction has a positive effect on the intention to use. The result of this study is that it is necessary to reduce the cheapness shopper feeling of consumers and to emphasize the price discount and scarcity so that the smart shopper feeling occurs in order to satisfy the consumers who purchase O2O service products.

This study investigated the consumer acceptance process of the fourth industrial revolution new product to be introduced into the market in the future. The 4th Industrial Revolution new products are technological advances compared to the existing ones. The technology acceptance model that was used in the past has been modified to reflect variables like the social effects of the 4th Industrial Revolution, expected experience, and perceived risk. Modified models were proposed and verified. Six representative new products of the 4th Industrial Revolution were selected and examined by 40 respondents, and the hypotheses were verified using programs such as SPSS and AMOS. And conclusions and implications are as follows. First, the innovativeness of the fourth industrial revolution new products influences positive evaluation factors such as expected experience and perceived usefulness and it also affect positively to the perceived risk. In addition, the expected experience of the fourth industrial revolution new products has a great effect on the perceived usefulness and social influence, but it didn't affect to the perceived risk. Like the results of the TAM model, purchase intention of the fourth industrial revolution new products are strongly influenced by perceived usefulness. Finally, the perceived risk of the new product of the 4th Industrial Revolution had no statistically significant effect on the purchase intention, and the social influence of the 4th Industrial Revolution had a significant effect on the purchase intention. In general, respondents are highly aware of the social impact of the Fourth Industrial Revolution and seem to be very positive in this respect.

The results of the present study on corporate social responsibility activities have different results for each researcher. This is considered to be the influence of the moderated variables depending on the relations among the variables. The purpose of this study is to propose anti-corporate emotion as a variable to moderate the relationship between social responsibility activities and outcome variables and to investigate its influence. The results and implications are as follows. Ethical responsibility activities and discretionary responsibility activities had effects on corporate attitude and corporate attitude affects consumers' purchase intention. This is consistent with many previous studies, which means that it is necessary to create a positive psychology for a firm or product in order to induce consumer behavior. In addition, in the group with high anti-corporate emotions, the effect is not significant even if the company has a lot of discretionary activities, but if the ethical responsibility is done, the negative attitude toward the company can be alleviated even if the anti- corporate emotion is high. This explains why many companies now have social contribution activities as an alternative to reduce the corporate crisis, but the effect is insufficient. Therefore, companies that want to carry out social responsibility activities should be interested first in the ethical management or ethical responsibility activities of companies.

The objective of the study was to find out whether the Super Bowl adverts with high Ad Meter scores had more advertising appeals related to U.S. culture in Hofstede's dimensions. The significance of the study lies in the analysis on U.S. consumer preferences on adverts in terms of culture under one of the most representative American sport event: Super Bowl. The study was based on a content analysis of top and bottom 10 Super Bowl adverts during a period of consecutive seven years 2005 through 2011. The top and bottom ten were grouped based on the Ad Meter scores by the USA Today. The number of adverts interpreted by two coders along with the author was 139. The coding results implies that adverts in the top 10 group carried more appeals connected to US culture in Hofstede dimensions, such as youth, untamed, and magic in uncertainty avoidance dimension. Meanwhile, such appeals as ornamental, vain, and status in high power distance dimension were mainly found in the bottom 10 adverts group. Grounded on the findings from the content analysis, links between the score levels and the presence of certain appeals may offer marketers a hint on what appeals they emphasize when producing adverts in a certain cultural bound, let alone Super Bowl adverts targeting TV viewers in the U. S. A.

The government promotes the 2050 carbon-neutral policy. Therefore, the concern to convert livestock manure into energy is increasing for the reduction of greenhouse gases generated in the livestock industry sector. In this study, the economic feasibility of the livestock manure solid fuel power generation facility, which is a major consumer of livestock manure solid fuel, was assessed to expand the demand for livestock manure solid fuel. The production cost of livestock manure solid fuel showed the lowest production cost of 97.4 thousand won/ton when dried using solid fuel at a 200 ton/day scale bio-drying facility. The livestock manure solid fuel power generation facility showed economic feasibility at a REC weight of 1.5 in the case of the bio-drying facility, so it was necessary to set a REC weight of 1.5 or more to expand the demand for livestock manure solid fuel. The conversion of livestock manure into solid fuel has various environmental benefits, such as the reduction of greenhouse gases and the effect of reducing non-point pollutants in the water system. Therefore, in order to expand livestock manure solid fuel production facility, it was required to review the feasibility including various environmental benefits.
