We analyze and study competition in differentiated product market using public data source. Understanding competitive market structure is critical for firms to assess how their products compete against other firms in a given market. In this paper, we estimate consumer demand, extend clout and vulnerability framework, and study competition among multi-product manufacturers in differentiated product market. For our empirical analysis, we adopt choice-based aggregate demand model and estimate consumer demand while accounting for unobserved product characteristics. Once we estimate consumer demand, we compute full price elasticity matrix and investigate intra- and inter- manufacturer substitutions among consumers. This research offers a framework for marketers to analyze and understand market structures, leading them to informed decisions.

The capabilities of the metaverse have been demonstrated by representative examples such as Roblox, Fortnite, and Zepeto, and it can enable gaming, social networking services, and other applications. Nevertheless, research on the metaverse has been fragmented owing to conflicting definitions, core values, and characteristics. This ambiguity in metaverse conventions has hindered related research, analysis, and policy establishment. As the confusion seems to aggravate, consistent concepts should be established. Although the coronavirus disease pandemic led to a collapse in metaverse usage, it is regaining public interest since 2022. To promote the metaverse development, we structure core values based on existing research and surveys of consumer expectations. We found that consumers perceive the metaverse as a realistic virtual space and a potential economic opportunity. Hence, it seems necessary to track the extent to which the metaverse core values satisfy consumer demands. Such core values should be consistently reflected in policies and technology development.

Increasing Public Concern : Pesticide residue is probably one of the fastest growing problems in regard to environmental contamination. Pesticide use in agriculture in this century has produced certain benefits, including a decrease in crop waste and an increase in crop yields and food quality. However, pesticide use also creates problems of having effects on the environment and remaining in food chain. The presence of pesticide residue in food, water, and soil has aroused public concern over potential health hazards. Despite information provided by national and private level agencies suggesting that food is safe, consumer groups worldwide are demanding assurance as to the safely of agricultural products.

These results of surveying public librarians can contribute to clearly identifying the status of CHI(consumer health information) services in Korea and to exploring future developments in CHI services. In this study, we investigated whether or not currently Korean public libraries are offering CHI services, whether or not they provide CHI reference services and the frequency of their use, and analyzed librarians' recognition of the need for Korean public libraries to provide the CHI services. The findings are as follows: 1) 70% of Korean public libraries are equipped with health-related books and medical journals, but the rate of libraries that are building CHI-related websites was very low at 5%. 2) The rate of providing the CHI reference services was only 30% of the surveyed public libraries. 3) 82.1% of public libraries did not provide educational programs related to CHI. 4) 82.1% of public libraries did not provide CHI-related services for vulnerable groups. 5) The rate of providing the CHI-related outreach programs and collaborating with CHI-related institutions was no more than about 20% each. These research findings can induce public librarians to provide CHI services in public libraries, and will contribute to activate the CHI-related research in Korea.

We can divide brand experience in the brand community of online blog into the following five types: sensuous experience, emotional experience, cognitive experience, behavioral experience, and relational experience. And this study is aimed at looking into what differences are among the effects those five have on the consumer-brand relationship. Also we wanted to analyse empirically what structural relations this consumer-brand relationship through the whole experience has with brand attachment and brand commitment. The outcome shows that emotional experience, cognitive experience and relational experience affect the consumer-brand relationship but sensuous experience and behavioral experience. And our analysis of what structural relations the consumer-brand relationship through brand experience has with brand attachment and brand commitment revealed that the consumer-brand relationship through brand experience has a direct effect on brand attachment but it doesn't have on brand commitment. Brand commitment was confirmed to be affected only through brand attachment. Finally, this is in agreement with the result of the precedent study that brand commitment is an effect variable of brand attachment.

The United States of America is one of the most favoring countries in which mandatory pre-arbitration clauses in the form of adhesion contract have been widely recognized and supported by courts and the Federal Arbitration Act. However, after the financial crisis in 2008 and the National Arbitration Forum scandal in 2009, in enacting the Dodd-Frank Wall Street Reform and Consumer Protection Act ('Dodd-Frank Act'), Section 1028(a) of the Act requires the newly created Consumer Financial Protection Bureau (CFPB) to provide Congress with a report on "the use of agreements providing for arbitration of any future dispute between covered persons and consumers". Section 1028(b) also grants the CFPB the authority to "prohibit or impose conditions or limitations on the use of an agreement between a covered person and a consumer for a consumer financial product or service providing for arbitration of any future dispute between the parties, if the Bureau finds that such a prohibition or imposition of conditions or limitations is in the public interest and for the protection of consumers." Pursuant to the Dodd-Frank Act, the CFPB issued a report entitled "2015 Arbitration Study: Report to Congress 2015 (Report)" in March 2015. This paper examines some major legal issues of the Report and makes a few recommendations for Korean financial institutions which entered into the U.S. financial market or has a plan to do so in the near future.

Purpose: Social Network Sites(SNS) have been grown up as a public communication channel consumer frequently participate in. Most of food service brands are utilizing social media for advertising recently. As a result of SNS marketing, food service brands anticipate positive outputs from SNS engagement and consumer brand engagement so that we need to verify structural relationship among SNS characteristics, SNS engagement and consumer brand engagement. Research design, data, and methodology: This study identifies that SNS characteristics have effects on SNS engagement and examines relationship between SNS engagement and behavioral engagement. We conceptualize SNS characteristics as information quality, hedonic level and interaction. Furthermore, SNS engagement is composed of SNS participation, positive word of mouth(WOM). In order to verify the purposes of this research, research model and hypotheses were developed. All constructs were measured with multiple items developed and tested in the previous studies. Sample data were collected from 433 online survey panels and analyzed by using SmartPLS 3.2.9. Result: The findings of this research are as follows. First, information quality is positively related with SNS participation. Hedonic level and interaction have impacts on SNS participation and positive WOM respectively. Second, SNS participation has positive effects on positive WOM. Third, both SNS participation and WOM influence behavioral engagement respectively. Conclusions: The implications demonstrate that SNS characteristics such as information quality and hedonic level and interaction exert effects for consumer to participate in SNS brand page. Meanwhile, hedonic level and interaction influence on positive WOM but information quality doesn't. SNS participation and positive WOM affect consumer to engage in specific brand behaviorally as well. Therefore, food service brand marketer is required to manage SNS information quality and hedonic level and interaction among members to encourage SNS participation and positive WOM. As SNS participation and positive WOM increases behavioral engagement of consumer, marketer needs to incentivize SNS participation and look after situation of positive WOM and respond swiftly.

As a result of climate change, mountain sediment disasters due to localized heavy rain and mountain development are occuring more frequently, thus, increasing social attention to and demand for soil erosion control projects. However, since 2011 Seoul Wumyeon Mountain landslide, the public is expressing increasing anxiety as well as negative perception regarding defective project results. Therefore, this study investigated promotional terms and information media related to soil erosion control projects according to the consumer in order to increase awareness of soil erosion control projects. In this study, the information consumers were divided into experts and the general public and conducted a survey related to promotional terms and media for communicating relevant information. In the result, the experts chose landslide prevention and recovery projects (41.8%) as an appropriate promotional term for soil erosion control projects. The general public, however, chose mountain sediment disaster prevention projects (32.5%) as the appropriate promotional term. However, the analysis showed that it would be necessary to develop an promotional term that can encompass the concept of 'disaster prevention' including forest and soil disaster as the word 'landslide' can suggest soil erosion control is limited to landslides only. In the survey regarding the media for communicating information related to soil erosion control projects according to the consumer type, the experts preferred radio and TV as media to communicate the relevant information, while, among the general public, the youths preferred social media such as Facebook and Twitter (22.22%) and adults radio and TV (34.07%), As for the most effective way to promote soil erosion control projects, the experts chose traditional promotinal media such as newspaper, radio, and TV (0.172) whereas the adults and youths preferred the internet and Facebook (0.089). It appears that using the preferred media for communicating information related to soil erosion control projects according to the consumer type will be effective way to promote soil erosion control projects.

Background: The National Institute of Environmental Research (NIER)'s classification of and airborne fraction ratio for consumer chemical products (CCP) does not reflect the characteristics of various product classifications. Objectives: The purpose of this study was to reclassify the types of spray products according to the diverse spray characteristics of CCPs to evaluate the airborne fraction ratio of representative spray types and to compare them with previous CCPs types and airborne fraction ratios. Methods: One thousand seven hundred two products were selected through market research, and 932 newly reported products were selected. After that, 200 were selected to evaluate products with potential inhalation exposure. After classifying six product types that are expected to show differences in the airborne fraction ratio according to the type of product, a final 38 products were selected for use in the airborne fraction ratio through random sampling. Results: CCP has been reclassified from two to six types so that the characteristics of all products are well-reflected. The NIER simply had two airborne fraction ratios, but the results of experiments with six types of products showed a significant difference in values (p<0.01). Airborne fraction ratios of propellant general foam, pump general aerosol, and pump trigger foam in spray type, which were not previously present in NIER, were 7.1%, 24.4%, and 3.5%, respectively. Conclusions: For the diversified types of CCPs, the newly proposed classification was more appropriate than the existing NIER classification. The airborne fraction ratio was also different for each type, so a new value was suggested.

Public acceptance of nuclear power is important for the government, the major stakeholder of the industry, because consensus is required to drive actions. It is therefore no coincidence that the governments of nations operating nuclear reactors are endeavoring to enhance public acceptance of nuclear power, as better acceptance allows stable power generation and peaceful processing of nuclear wastes produced from nuclear reactors. Past research, however, has been limited to epistemological measurements using methods such as the Likert scale. In this research, we propose big data analysis as an attractive alternative and attempt to identify the attitudes of the public on nuclear power. Specifically, we used common big data analyses to analyze consumer opinions via SNS (Social Networking Services), using keyword analysis and opinion analysis. The keyword analysis identified the attitudes of the public toward nuclear power. The public felt positive toward nuclear power when Korea successfully exported nuclear reactors to the United Arab Emirates. With the Fukushima accident in 2011 and certain supplier scandals in 2012, however, the image of nuclear power was degraded and the negative image continues. It is recommended that the government focus on developing useful businesses and use cases of nuclear power in order to improve public acceptance.
