Plural governance system in which firms use vertical integration and market governance simultaneously are widely used across various marketing context. Typical examples of plural governance include franchise systems, in which firms own and operate some unit themselves while licensing the operation of some of their units to franchisees. Despite many scholars have attempted to explore the structure of plural governance over decades, there are few insights into its determinants. In this study, we examine the relationship between the proportion of outlets franchised and several franchisor's characteristics based on the perspectives of transaction cost analysis, resource scarcy theory and agency theory. Using franchisor data in Korean Franchise Disclosure Document over the 2006-2009 period, we test the effect of franchisor size, system growth rate, franchise fee, initial investment, and risk sharing on the proportion of outlets franchised. Except for the effect of system growth rate, the results of a series of multiple regression analysis supported the negative effects of franchisor size, franchise fee, initial investment and risk sharing on the proportion of outlets franchised.

The purpose of this study is to screen for the effects of climate change and climate change adaptation in the insurance industry. There is now a consensus that the climate is changing, with potential risk to the global economy and human health and so on. On the other hand, unknown is the extent to which insurance business pattern have already been affected. But the increase in damage due to climate change is likely to raise insurance company losses. In this regard, I conduct especially an effects of the insurance industry on climate change. And than, I analyzed what insurance companies would do to lessen the impact of climate change. As a result, the impact of climate change on the insurance industry is a huge increases in claims due to disasters and diseases arising from climate change. And another thing is growth in climate change-related legislation, regulations and reporting requirements such as financial soundness regulation and climate change risk disclosure. Therefore, the insurance industry needs to build a climate change adaptation strategies include capital raising, liquidity of assets, faithful debt management and so forth.

Technology transfer from a multinational company to a local subsidiary is essential for successful local market operations. This study aims to analyze the impact of market, cultural and institutional environmental factors on international technology transfer and innovation performance based on the S-C-P paradigm. We collected data from one hundred ninety-five subsidiaries of Korean parent firms located in seventeen countries and used structural equation modeling to test hypotheses. The analysis findings are as follow; First, both market and cultural environment directly affect international technology transfer. However, institutional environment such as protection of intellectual property does not affect international technology transfer. Due to the less risk of technology disclosure involved in technology transfer within the MNE organization can be not relationship between protection of intellectual property in the host country and the foreign subsidiary's transfer of technology. The risk of infringement of intellectual property is relatively low in intra-firm transfer of technology. Second, the technology introduced from the parent company has a positive effect on the innovation performance of local subsidiaries. This implies that multinational companies that have entered unfamiliar overseas markets should be able to effectively transfer the inherent advantages of the parent company to their overseas subsidiaries, and that their ability to adapt to the local environment is important.

본 연구의 목적은 한국거래소에 상장되어 있는 KOSPI기업과 KOSDAQ기업을 대상으로 최대주주의 변경과 관련된 정보가 적자보고에 미치는 영향을 실증분석하는 것이다. 구체적으로, 최대주주 변경 유형 중에서 최대주주의 잦은 변경이 나타난 기업의 적자보고를 살펴보기 위하여 기업의 적자보고에 미치는 영향을 통제하고 로짓 회귀분석의 방법을 적용하여 실증분석한다. 분석결과, 회계기간 내 2회 이상 최대주주가 변경된 기업은 적자보고의 기업위험이 다른 기업 보다 더 높은 것으로 나타났다. 이는 한국거래소의 투자위험 공시사항인 최대주주의 잦은 변동이 적자보고와 같은 투자위험 상황으로 나타날 수 있음을 나타낸다. 본 연구는 상장기업을 대상으로 최대주주 변경과 관련한 변동이 시장위험에 영향을 미친다는 증거를 제시하여 한국거래소 전자공시(KIND) 투자유의사항의 정보적 역할을 확인하였다는 점에서 선행연구에 추가적인 공헌점을 가진다.

Purpose - Using unexpected changes in geopolitical tensions on the Korean peninsula as a quasi-natural experimental setting, we examine whether and how geopolitical risks travel across borders through firm-level imports and exports linkages. We also test whether the effects are driven by either imports or exports and assess whether firms can effectively hedge themselves against geopolitical risks. Design/methodology - We focus on a series of unanticipated geopolitical events taken place in Korea in 2018. Making use of the shocks to geopolitical climate, we identify five milestone events toward peace talks. We employ the event studies methodology. We examine heterogenous firm-level stock price reactions around key event dates depending on firms' exposure to geopolitical risks. As a measure of firms' exposure to geopolitical risks in Korea, we utilize a text-based measure of firm-level trade links. When a firm announces and discusses its purchase of inputs from Korea or sales of outputs to Korea in their annual disclosure filings, we define a firm to have a trade relationship with Korea and have exposure to Korean geopolitical risks. Similarly, we use a measure of a firm's hedging policies based on a firm's textual mention of the use of foreign exchange derivatives in their annual disclosure. Findings - We find that U.S. firms that have direct trade links to Korea gained significantly more value when the intensity of geopolitical risks drops compared to firms without such trade links to Korea. The effects are pronounced for firms purchasing inputs from or selling outputs to Korea. We find that the effectiveness of foreign exchange hedging against geopolitical risks is limited. Originality/value - We document the international transmission of geopolitical uncertainty through trade linkages. Export links as well as import links serve as important nexus of transmission of geopolitical risks across borders. Hedging strategies involving foreign-exchanges derivatives do not seem to insulate firms again geopolitical risks. With the recent movements of localization and reshuffling of the global value chain, our results suggest a significant impact of geopolitical risks in Korea on the construction of the global value chain.

Objectives: This study investigated the impact of socioeconomic factors and sexual orientation-related attributes on the rates of coronavirus disease 2019 (COVID-19) vaccination and infection among men who have sex with men (MSM). Methods: A web-based survey, supported by the National Research Foundation of Korea, was conducted among paying members of the leading online portal for the lesbian, gay, bisexual, transgender, or queer and questioning (LGBTQ+) community in Korea. The study participants were MSM living in Korea (n=942). COVID-19 vaccination and infection were considered dependent variables, while sexual orientation-related characteristics and adherence to non-pharmacological intervention (NPI) practices served as primary independent variables. To ensure analytical precision, nested logistic regression analyses were employed. These were further refined by dividing respondents into 4 categories based on sexual orientation and disclosure (or "coming-out") status. Results: Among MSM, no definitive association was found between COVID-19 vaccination status and factors such as socioeconomic or sexual orientation-related attributes (with the latter including human immunodeficiency virus [HIV] status, sexual orientation, and disclosure experience). However, key determinants influencing COVID-19 infection were identified. Notably, people living with HIV (PLWH) exhibited a statistically significant predisposition towards COVID-19 infection. Furthermore, greater adherence to NPI practices among MSM corresponded to a lower likelihood of COVID-19 infection. Conclusions: This study underscores the high susceptibility to COVID-19 among PLWH within the LGBTQ+ community relative to their healthy MSM counterparts. Consequently, it is crucial to advocate for tailored preventive strategies, including robust NPIs, to protect these at-risk groups. Such measures are essential in reducing the disparities that may emerge in a post-COVID-19 environment.

Previous research assessed media reporting on nuclear accidents and risks, whilst studies about the Fukushima accident focused on the impact of the Internet on coverage of the incident. However, little research has addressed news framing or comparisons of the perceptions of journalists in relation to reporting nuclear accidents. The aim of this study is to apply framing analysis to news content in The New York Times, the Los Angeles Times, and USA Today about the Fukushima accident. It explores the question of how journalists view reporting on complex events. Content analysis of these three newspapers shows that conflict, responsibility, and economic consequences were the most frequently used frames. According to the journalists interviewed, the biggest problem was the inability to assess information due to contrary positions held by experts. It is argued that the Fukushima accident was framed as a conflict of experts and officials' opinions, utility and government officials' responsibility, and economic consequences for the United States. Adherence to professional norms of objectivity and impartiality was signified as the best approaches to risk reporting.

A novel key sharing fuzzy vault scheme is proposed based on the classic fuzzy vault and the Diffie-Hellman key exchange protocol. In this proposed scheme, two users cooperatively build their fuzzy vault for their shared key using their own biometrics. Either of the users can use their own biometrics to unlock the fuzzy vault with the help of the other to get their shared key without risk of disclosure of their biometrics. Thus, they can unlock the fuzzy vault cooperatively. The security of our scheme is based on the security of the classic fuzzy vault scheme, one-way hash function and the discrete logarithm problem in a given finite group.

We briefly review the problem of statistical disclosure control under differential privacy model, which entails a formal and ad omnia privacy guarantee separating the utility of the database and the risk due to individual participation. It has born fruitful results over the past ten years, both in theoretical connections to other fields and in practical applications to real-life datasets. Promises of differential privacy help to relieve concerns of privacy loss, which hinder the release of community-valuable data. This paper covers main ideas behind differential privacy, its interactive versus non-interactive settings, perturbation mechanisms, and typical applications found in recent research.

When producing a business card, there is always a risk for exposing personal information as the information from the business card application is saved in the computer of the printing agency. The information that goes into the business card application file, such as name, mobile phone number, and e-mail address is not encrypted, which makes it easy to access. This study was conducted in order to find a way to automatize the business card application process by encrypting the information entered into the business card application file, simplifying the business card application process, minimizing the workload and by directly linking to the print shop to remove the print file after completing the printing of the business card.
