정성민,김경은 국제e-비즈니스학회 2022 e-비즈니스 연구 Vol.23 No.5

As the use of mobile shopping increases due to the expansion of the O2O market, the need for theoretical research on the behavior and psychological factors of mobile coupon users is emerging. The purpose of this study was to examine the behavioral and psychological process of coupon use, the effects of practical benefits and hedonistic benefits on the feeling of smart consumers and those of cheaper consumers were investigated. Investigation of statistics for O2O services coupon, feelings of smart shopper, feelings of cheaper shopper, purchase review reward. In addition, we would like to examine the consumer's reaction when a coupon is used as a reward for reviews. The specific objectives of this study are as follows. First, we will examine the value of O2O service coupons by discussing the existing coupon values. Second, it is suggested that the coupon obtained as a reward for product reviews requested by service providers in O2O service can perceive social benefits as well as psychological benefits, and discusses it through empirical verification. Third, compared to offline coupons, we would like to suggest that the value of O2O coupons can have a greater effect on psychological benefits. The results of study, the coupon obtained as a reward for a purchase review showed a high feeling of a smart consumer. And for each coupons there was no difference in the feeling of smart consumers depending on the discount rate. It can be seen that the effort to acquire the coupon is independent of the discount rate as a cost. Therefore, if coupons are provided to lower the cost of acquiring coupons when inducing purchase reviews, it will increase the feeling of smart consumers and ultimately increase the redemption rate of mobile coupons. For this, it is necessary to control and manage the behavioral characteristics of coupon use, O2O시장의 확대로 모바일 쇼핑 사용이 증가하면서 모바일쿠폰 사용자의 행동 및 심리적 요인에 대한이론적 연구의 필요성이 대두되고 있다. 이에 본 연구는 쿠폰 사용의 행동 및 심리적 과정에 초점을 두어실용적 혜택과 쾌락적 혜택이 현명한 소비자의 느낌과 인색한 소비자의 느낌에 미치는 영향을 살펴보았다. 또한 긍정적 구전효과를 의도적으로 발생시키기 위한 노력으로 사용후기에 대한 보상으로 쿠폰이 사용될때 소비자의 반응을 살펴보고자 한다. 본 연구의 구체적인 목적은 다음과 같다. 첫째, 기존 쿠폰가치에 대한논의를 통해 O2O서비스 쿠폰가치에 대해 살펴보고자 한다. O2O서비스의 쿠폰가치인 경제적, 심리적 혜택및 사회적 비용은 기존 오프라인에서만 방문하는 것과는 상이할 것으로 예상된다. 둘째, O2O서비스에서서비스 제공자가 요구하는 제품사용후기에 대한 보상으로서 얻게 되는 쿠폰은 심리적 혜택과 더불어 사회적혜택을 지각할 수 있음을 제시하고 실증적 검증을 통해 논의하고자 한다. 셋째, 오프라인 쿠폰과 비교하여O2O쿠폰의 가치가 심리적 혜택에 보다 큰 영향을 줄 수 있음을 제시하고자 한다. 분석 결과에 따르면 구매후기에 대한 보상으로 얻은 쿠폰은 현명한 소비자의 느낌이 높게 나타났다. 그리고 각 쿠폰은 할인율에 따라서는현명한 소비자의 느낌에 대한 차이가 나타나지 않았다. 이는 쿠폰을 획득하기 위한 노력이 비용으로서 할인율과는 무관함을 알 수 있다. 따라서 구매후기를 유도할 때 쿠폰획득비용을 낮출 수 있게 쿠폰을 제공한다면현명한 소비자의 느낌을 높여주고, 결국 모바일 쿠폰 상환율을 높일 수 있을 것이다. 이를 위해서는 쿠폰사용의 행동적 특성을 통제하고 관리하는 것이 필요하다.

정성민,김경은 국제e-비즈니스학회 2023 e-비즈니스 연구 Vol.24 No.4

Research Purpose: This study aims to examine anticipated regret within the context of Online-to-Offline (O2O) services in more detail. Firstly, we aim to investigate anticipated regret within the O2O service context, which has not been extensively discussed in previous research. We anticipate differences in results due to the unique characteristics of O2O services compared to conventional contexts. Secondly, we intend to present the perception of psychological benefits in resolving anticipated regret based on product types within the O2O service environment. We plan to empirically validate this concept and engage in a comprehensive discussion. Lastly, we seek to examine how the psychological benefits of resolving anticipated regret differ in situations of collective decision-making within the O2O service context. This examination will help shed light on variations in the perception of psychological benefits in different decision-making scenarios. Research Methods: To achieve this goal, we divide the service types into O2O delivery services and offline visit services, and explore the influence of product types (virtuous products vs. vice products) and social consumption situations (with companions vs. alone) on anticipated regret. Results in Research: Firstly, it was observed that O2O service purchases yield a higher level of psychological benefits compared to offline purchases. Secondly, the level of anticipated regret experienced during offline purchases is higher for vice products. Thirdly, psychological benefits obtained from O2O service purchases are greater for virtuous products. Lastly, when comparing the level of psychological benefits obtained with the presence of companions, it was found that the utilization of O2O services with companions results in higher psychological benefits than offline purchases, regardless of the product type. Research Conclusion: The findings of this study confirm that the characteristics of O2O services can emphasize such psychological rewards and enhance consumers' experience of psychological benefits. Anticipated regret experienced during offline usage was higher for vice products. These research outcomes suggest that consumers emphasize psychological aspects when making product choices, as evidenced by these results. Suggestions in Research: Overall, this study's results contribute to understanding the intricate relationship between anticipated regret, O2O services, and consumer decision-making, while also suggesting directions for future research to explore more nuances in this area. 본 연구는 O2O 서비스에서의 선택 동기와 예상된 후회에 관한 연구를 통해 선한 제품과 악한 제품의선택에 대한 영향을 탐구하고자 하였다. 또한 단독 소비와 공동 소비의 차이를 고려하여 선택 동기와 예상된후회에 미치는 영향을 분석하였고, 이를 통해 O2O 서비스 환경에서 소비자들의 선택과 소비 행동에 대한이해를 높이고자 하였다. 분석 결과에 따르면, 첫째, O2O 서비스 구매 시 오프라인 구매 상황보다 더 높은수준의 심리적 혜택을 얻는 것으로 나타났다. 둘째, 오프라인 구매 시 발생하는 예상된 후회 수준은 악한제품에서 더 높은 예상된 후회를 느끼는 것으로 나타났다. 셋째, O2O 서비스 구매 시 얻는 심리적 혜택은선한 제품에서 더 높은 심리적 혜택을 느끼는 것으로 나타났다. 마지막으로 동반자가 존재할 때 얻는 심리적혜택 수준을 제품 유형에 따라 변화하는지 비교해본 결과, 동반자가 존재할 때 O2O 서비스 이용이 오프라인이용보다 더 높은 심리적 혜택을 느낀 것으로 나타났다. 이러한 연구 결과는 소비자들이 제품 선택 시 심리적측면을 강조하여 제품 유형을 선택한다는 사실을 시사한다. 향후 연구에서는 예상된 후회에 영향을 미치는추가적인 서비스 상황 요인들을 확인하고, 이와 더불어 예상된 후회에 미치는 다양한 요인들을 조사하고분석함으로써 더욱 포괄적인 결과를 도출할 필요가 있다.

Background and Objectives : Aerodynamic investigation is valuable information about the efficiency of the larynx in translating air pressure to acoustic signal. The normal data of the Korean has been reported, but there is no basic data of professional western classical singers who have learned how to control the flow of expiratory air for singing. The purpose of this study was to investigate the normal aerodynamic data of korean professional western classical singers and compare this with that of the Korean Materials and Methods : 50 Korean western classical singers were studied. Expiratory lung pressure combined with measurements of the mean air flow rate, voice frequency and intensity were measured with the aerodynamic test using airway interruption method. These data were compared with normal data of untrained normal adults. Results and Conclusions : The voice frequency and the voice intensity were increased in the western classic singers, but the mean air flow rate and the expiratory air pressure of the classical singers were within the same range of the untrained normal adults. This result means that western classical singers can change the loudness and pitch with a little increased or decreasing the mean air flow and the expiratory air pressure.

Pseudocercospora leaf spot was major disease of grape cultivar ‘Campbell Early’ in Korea. Leaf spot first appeared in early June and rapidly dispersed to other leaves through rainy season. Disease progress of leaf spot by Pseudocercospora vitis in plastic green house, in the two provinces (Gimje and Gimcheon), were investigated in 2007. Differences of Infected leaves (%) between cultivation systems were observed in field and plastic green house, but there was no difference between provinces. Micro environmental factors, such as temperature and relative humidity, were correlated with infected leaves by PROC REG procedure of SAS (Statistical Analysis System). As a result, regression model best described (R2=0.95**) the infected leaves as a function of the interaction of cumulated temperatures; Y (Infected leaves)=−7.0101+0.0496×20Hcum (Cumulated hour above 20 degree)+0.0208×20cum (Cumulated temperature above 20 degree)−0.2781× 25Hcum (Cumulated hour above 25 degree). A statistics model was shown that cumulated hour and temperature above specific degree were critical factor for Pseudocercospora leaf spot on the grapevine leaves in plastic green house.
