식생활 라이프스타일이 편의점 도시락 구매의도에 미치는 영향: 편의점 도시락의 지각된 품질의 매개역할을 중심으로
이명철 한국외식경영학회 2024 외식경영연구 Vol.27 No.2
본 연구에서는 식생활 라이프스타일이 편의점 도시락 구매의도에 미치는 영향 관계와 지각된 품질의 매개역할을 살펴보고자 하였다. 본 연구는 2024년 2월 19일부터 2월 25일까지 서울, 경기, 대전, 광주 지역에서 편의점 도시락을 구매해 본 경험이 있는 소비자를 대상으로 편의표본추출 방법에 의해 설문조사를 실시하였다. 설문지는 251부를 최종 분석자료로 사용하였으며, SPSS 23.0 패키지프로그램을 이용하여 분석을 실시하였다. 분석을 요약하면 다음과 같다. 첫째, 식생활 라이프스타일 중 건강추구형이 편의점 도시락 구매의도에 유의한 영향을 미치는 것으로 나타났다. 반면, 편의추구형은 편의점 도시락 구매의도에 유의한 영향을 미치지 않는 것으로 나타났다. 둘째, 지각된 품질은 식생활 라이프스타일 중 건강추구형과 편의점 도시락 구매의도 간에 매개역할을 하는 것으로 나타났다. 본 연구결과는 소비자들의 식생활 라이프스타일을 파악함으로써 편의점 도시락 제품 개발 및 매출 증대에 기여할 수 있는 기초자료를 제공하고자 하였다. We examined the impact of dietary lifestyle on purchase intention of convenience store lunch boxes and the mediating role of perceived quality. This study conducted a survey using the convenience sampling method targeting consumers who had experience purchasing convenience store lunch boxes in Seoul, Gyeonggi, Daejeon, and Gwangju from February 19 to February 25, 2024. We used 251 copies of the questionnaire as final analysis data, and analysis was conducted using the SPSS 23.0 package program. The analysis is summarized as follows. First, the health-seeking type of dietary lifestyle had a significant impact on the purchase intention of convenience store lunch boxes. On the other hand, the convenience-seeking type had no significant effect on the purchase intention of convenience store lunch boxes. Second, perceived quality was found to play a mediating role between health-seeking dietary lifestyle and purchase intention of convenience store lunch boxes. The results of this study provided basic data that could contribute to the development of convenience store lunch box products and increase sales by understanding consumers' dietary lifestyles.

Purpose: We investigated whether myocardial SPECT had additional usefulness to clinical, functional or surgical indices for the preoperative evaluation of cardiac risks in noncardiac surgery. Materials and Methods: 118 patients (M: F=66:52, 62.7±10.5 years) were studied retrospectively. Eighteen underwent vascular surgeries and 100 nonvascular surgeries. Rest T1-201/stress Tc-99m-MIBI SPECT was performed before operation and cardiac events (hard event: cardiac death and myocardial infarction; soft event: ischemic ECG change, congestive heart failure and unstable angina) were surveyed through perioperative periods (14.6±5.6 days). Clinical risk indices, functional capacity, surgery procedures and SPECT findings were tested for their predictive values of perioperative cardiac events. Results: Peri-operative cardiac events occurred in 25 patients (3 hard events and 22 soft events). Clinical risk indices, surgical procedure risks and SPECT findings but functional capacity were predictive of cardiac events. Reveible perfusion decrease was a better predictor than persistent decrease. Multivariate analysis sorted` out surgical procedure risk (p=0.0018) and SPECT findings (p=0.0001) as significant risk factors. SPECT could re-stratify perioperative cardiac risks in patients ranked with surgical procedures. Conclusion: We conclude that myocardial SPECT provides additional predictive value to surgical type risks as well as clinical indexes or functional capacity for the prediction of preoperative cardiac events in noncardiac surgery.
