  • Purpose: This study aims to verify sellers' economic incentives for voluntarily disclosing negative information in online markets and provide practical guidelines to online sellers in terms of whether, when, and how sharing low quality to buyers increase sales. Research design, data and methodology: Our model examines the number of bidders in Internet auctions to measure potential demand and uses count data analysis following previous studies that have also analyzed the number of bidders in auctions. After checking over-dispersion and zero-inflation in our data, we have run a Poisson regression to analyze the effect of sharing negative information on sales. Results: This study presents a counterintuitive result that low-quality sellers can increase their demand by fully disclosing negative information in an online market, if appropriate risk-reducing methods are employed. Our finding thus shows that there exists economic incentive for online sellers to voluntarily disclose negative information about their products, and that the context of transactions may affect this incentive structure as the incentive varies across product categories. Conclusions: As the positive impact of disclosing negative information has rarely been studied so far, this paper contributes to the literature by providing a unique empirical analysis on the impact of sellers' honesty on sales. By verifying economic incentives of disclosing low quality with actual online sales data, this study suggests practical implications on information disclosure strategy to many online sellers dealing with negative information.

  • Purpose This research aims to study the changes in recruitment needed for the growth and survival of companies in the rapidly changing industry. In particular, we built a real company's worklist accounting for the rapidly advancing data-driven digital transformation, and presented the capabilities and conditions required for work. Design/methodology/approach we selected 37 jobs based on NCS to develop the employment search requirements by analyzing the business characteristics and work capabilities of the industry and company. The business specification indicators were converted into a matrix through the TF-IDF process, and the NMF algorithm is used to extract the features of each document. Also, the cosine distance measurement method is utilized to determine the similarity of the job specification conditions. Findings Companies tended to prefer "IT competency," which is a specification related to computer use and certification, and "experience competency," which is a specification for experience and internship. In addition, 'foreign language competency' was additionally preferred depending on the job. This analysis and development of job requirements would not only help companies to find the talents but also be useful for the jobseekers to easily decide the priority of their specification activities.

  • Purpose: The purpose of this study is to analyze the measurement results of the financial comprehension test conducted ten times in order to study the financial comprehension. Research design, data, and methodology: In this study, correct answer rates in the Economics and Finance Literacy Certification Test were analyzed across ten rounds of tests taken by 6,662 high school students in Korea. Result: The analysis revealed that Korean high school students' level of financial literacy generally increased as the grade level increased, and the correct answer rates of students at autonomous high schools and special-purpose high schools were statistically different from those of students at general academic high schools and specialized high schools. Conclusion: We can therefore infer that students at specialized high schools face limitations in tackling financial problems due to their lack of proficiency in interpretation and calculation of data necessary for real life financial decision-making. In contrast, students at general academic high schools, special-purpose high schools, and autonomous high schools who do not learn finance as a part of their official curriculum at school were lacking in basic financial knowledge as well as knowledge about the financial system compared to students at specialized high schools, highlighting the need for a measure to address the deficiency.

  • Purpose - The purpose of this paper is to suggest countermeasures to reduce the damage of manufacturers in halal industries and to increase the transparency of the halal market along with raising some problems of halal supply chain management (HSCM). Design/methodology/approach - To achieve to the aim of this research, halal supply chain is categorized as a green zone or a red zone according to the possibility of cross-contamination, and the study introduces 2 examples in Malaysia and Indonesia regarding cross-contamination. Findings - More than 70% of the companies producing halal-certified products are, ironically, non-Muslim suppliers under the halal certificate system and by using halal supply chain. Most Muslim countries do not exercise control over the completed halal supply chain. In most Muslim countries which do not exercise control over halal supply chain properly, there is always a possibility of cross-contamination of products during the processes of distribution. Research limitations/implications - This research has been conducted by accessing cases in halal supply chain. These cases are found in some Muslim countries, not all Muslim countries. Nevertheless, the authors found the possibility of these cross-contaminations in all Muslim countries, and it will damage the halal market. Originality/value - While existing studies have focused on protecting Muslim consumers by ensuring the integrity of halal products in halal supply chain, there is no research on how to protect halal product manufacturers as another important axis of halal SCM.

  • Purpose-Meat plays an important role in the Chinese daily diet, however, due to the spread of COVID-19, food supply and safety have become a major concern. The safety and health features of chilled fresh meat have attracted the attention of consumers. To study consumers' purchasing behavior and willingness to pay for chilled meat under the influence of the epidemic. Research methodology- The data were obtained by questionnaire survey, major issues include consumers' meat consumption habits in the wake of the COVID-19 and their awareness of meat product quality labels. In addition, the gender, age, family income, and other basic personal information of the interviewees were also counted. Based on the binary Logit regression method, we study consumers' purchasing behavior and willingness to pay for chilled meat under different demographic characteristics. Results-The results showed that brand and quality certification are important factors influencing purchases. In addition, the presence of children under the age of 12 in the household and the level of income and education also influence consumers' purchase intention of the chilled fresh meat. However, mart promotions and city ratings can significantly lower consumers' propensity to buy the chilled fresh meat. Apart from this, such factors as gender, age, and living conditions have no significant influence on consumers' purchase of chilled fresh meat.

  • 보이스피싱은 가짜 금융기관, 검찰청, 경찰청 등을 사칭하여 개인의 인증번호와 신용카드 정보를 알아내거나 예금을 인출하게 하여 탈취하는 사이버 범죄이다. 최근에는 교묘하고도 은밀한 방법으로 보이스피싱이 이루어지고 있다. '18~'21년 발생한 보이스피싱의 추세를 분석하면, 보이스피싱이 발생되는 시기에 예금 인출이 급격하게 증가하여 시계열 분석에 모호함을 주는 계절성이 존재함을 발견하였다. 이에 본 연구에서는 보이스피싱 발생 추이의 정확한 예측을 위해서 계절성을 X-12 계절성 조정 방법론으로 조정하고, ARIMA 모형을 이용하여 2022년 보이스피싱 발생을 예측하였다.

  • Purpose: This study is to analyze the purchasing process and distribution management requirements for teaching materials that have important meaning in the practical field of preschool education. Research design, data and methodology: A structured questionnaire was used to survey 103 childcare staffs regarding the purchasing process and distribution managements. The collected data underwent Likert's 5-point scale analysis and keyword grouping. Additionally, ANOVA was conducted to examine the distribution management demands based on demographic characteristics. Results: The purchasing of teaching materials involved more offline channels than online, and the purchase decisions were predominantly made by principals rather than teachers. Although the purchasing process is similar to that of general businesses, there are difficulties in purchasing due to the disorganized distribution channels and limited accessibility to product information. Additionally, the management of inventory for teaching materials is challenging due to limited personnel and storage. Childcare staffs have requirements for classification systems, evaluation criteria, environments and policies related to teaching materials distribution. The need to introduce a teaching material evaluation and certification system to ensure quality was not high. Conclusions: Most of the respondents recognized that strict management and measures should be taken for the distribution of teaching materials. There were differences in the demand of teaching material distribution depending on the respondents' status, age, education, and experience.

  • Purpose: South Korea is one of the markets where diverse and innovative cuisines are being tried. Therefore, the expectations for Michelin star restaurants in South Korea are high. The expected value of a Michelin star restaurant consists of both hedonic and utilitarian aspects of the dining experience. These consumer expectations affect visit intention. Research design, data, and methodology: The survey period was from October 10, 2023 to October 18, 2023, and 302 copies were used for hypothesis verification. Result: Hedonic expected value was found to have a significant positive influence on short-term and long-term visit intention, but had no significant effect on mid-term visit intention. Utilitarian expected value was found to have a significant positive influence on short-term and mid-term visit intention, but did not appear to have a significant effect on long-term visit intentions. Short-term visit intention was found to have a significant positive influence on mid-term visit intention, and mid-term visit intention was found to have a significant positive influence on long-term visit intention. Conclusions: The theoretical implications are restaurants need to utilize third-party certification, such as the Michelin Guide. The practical implication is that Michelin star restaurants should provide expected value to increase short-term visit intention.

  • 물발자국은 EU가 추진하고 있는 자원효율적인 유럽을 위한 로드맵(Roadmap to a Resource Efficient Europe)을 바탕으로 제시된 친환경제품 시장통합정책(Single Market for Green Product initiative)의 중요한 구성요소이다. 2014년 7월 EU 회원국의 주도로 물발자국 산정 국제표준(ISO 14046)이 제정되었으며 우리나라도 한국산업표준(KS I ISO 14046)으로 2015년 4월 부합화를 완료하였다. 국제표준(ISO 14046)에 기반을 둔 인증제도가 도입되는 경우, 기반을 갖추지 못한 인도, 베트남 등의 개도국에게는 수출시 무역장벽이 될 수 있으므로 우리나라는 이를 역이용하기 위한 전략을 수립해야 한다. 한편, 물발자국은 전과정평가(LCA)를 적용한 유사 발자국(예, 탄소발자국)인증과 비교할 때 국지적(Local) 환경영향을 고려하도록 되어 있어, 우리나라에서 생산 및 제조되는 제품들은 우리나라 수역에 미치는 영향을 고려해야 한다. 따라서 물발자국 산정방법은 국내외 호환을 위해 표준에 적합해야 하며, 우리나라의 물 환경을 고려하기 위해서 우리나라 적합한 물발자국 산정계수들의 도출이 필요하다. 이를 위해 이 연구에서는 국제표준을 바탕으로, 현재 국내 외에서 진행된 물발자국 산정연구를 검토하고 국내 기존 물 자원 관련 통계자료 분석을 통해 물발자국 방법론의 국내 적용 가능성을 확인하였다.
