정난희,박효은,조항 한국상담학회 2021 Journal of Asia Pacific counseling Vol.11 No.2

This study investigated college students’ psychological distress within the context of the novel coronavirus disease 2019’s (COVID-19). A questionnaire was administered to 209 college students in South Korea. Frequency analysis, one-way analysis of variance, and t-test were conducted to analyze the collected data using the JAMOVI program. The results revealed that nearly 20% participants reported experiencing severe stress, anxiety, and depression due to COVID-19. Further, female students scored higher at all levels. The level of psychological distress of the students who get support for their living expenses was significantly higher than that of students making money through part-time jobs. The depression level of students attending face-to-face classes was significantly higher than those who did not. The grade and housing type were not significant aspects. Based on these results, a discussion was then presented. This study thereby provided foundational data for identifying the psychological impacts of COVID-19 on South Korean college students.

Purpose: This study was carried out to optimize the level of sugar addition during the preparation of mushroom (Pleurotus eryngii) pickles without influencing degree of preference. Methods: The salinity, sugar contents, moisture contents, pH, hardness, antioxidant activity and sensory evaluation of mushroom pickles were measured. Results: The salinity and sugar content during storage of mushroom pickles decreased significantly as the level of sugar added decreased. The moisture content increased in the case of mushroom pickles added with 10% sugar. As the level of sugar decreased, the pH and hardness decreased during the three week storage period. L (lightness) value was not different from that of the control group (20%) until the level of added sugar was 10%, whereas a (redness) and b (yellowness) values increased. Antioxidant activity increased with decreasing sugar content. According to sensory evaluation, mushroom pickles containing 15% and 10% added sugar, 15% added sugar, 15% and 10% added sugar, 10% added sugar and the control, 10% and 15% added sugar, and 15% and 10% added sugar showed higher values for appearance, flavor, taste, texture, clarification degree and overall acceptance in order. Conclusion: The results of this study suggest that the sugar contents are reduced to 10%, which is an optimal level that does not significantly influence overall acceptance.

The Smaller, The Better: How Size Perception Influences Anticipated Guilt in Hedonic Consumption

정난희,김영희 한국전략마케팅학회 2025 마케팅논집 Vol.33 No.1

Previous research on food marketing has primarily focused on the trade-off between pleasant but unhealthy and healthy but less pleasant options. While consumers are aware that healthy choices are rational, they often succumb to temptations, which often result in feelings of regret and guilt. Based on the theory of bounded rationality, the current research examines how consumers justify their irrational choices to reduce their anticipated guilt. Specifically, we suggest that perceived portion size influences consumers’ anticipated guilt, which in turn affects their food choices. We propose that for pleasant but unhealthy foods(i.e. hedonic foods), perceiving the food portion smaller reduce a consumer’s anticipated guilt, which leads to higher purchase intention. The results of two experiments show that smaller perceived size leads to decreased anticipated guilt for consuming hedonic foods. Our findings show that, in the context of hedonic foods, a smaller perceived portion size may bring more positive feelings to consumers by mitigating anticipated guilt for consuming unhealthy foods. The findings offer important implications for marketing strategies, suggesting that altering size perception may help consumers justify their irrational decisions, especially for pleasant but unhealthy food consumption(e.g. dessert).

The Effect of Unfamiliarity on Perceived Control and Time Perception

정난희,박세범 한국전략마케팅학회 2024 마케팅논집 Vol.32 No.1

While there has been extensive research on how familiarity affects time perception, there remains a significant gap in studies examining the impact of unfamiliarity on time perception. Therefore, we aim to identify the opposite mechanism and explore the impact of unfamiliarity on time perception. When navigating unfamiliar paths, efforts are made to quickly avoid or escape from unfamiliar situations. This process involves significant cognitive effort, giving rise to various emotions such as anxiety, restlessness, and tension. Individuals facing unfamiliar situations may also have a low perceived sense of control over the situation or task. Therefore, the current research aims to examine the influence of unfamiliarity on perceived control and time perception. Specifically, we seek to clarify the impact of presenting unfamiliar tasks through experiments on perceived control and time perception. The experimental results align with our expectations, indicating that in the case of unfamiliar tasks (vs. familiar tasks), perceived control was lower, leading to a longer perceived time than the actual time taken to perform the task. Based on these discussions, we present academic and practical insights.

정난희,이종민,이선경 대한부인종양학회 2010 Journal of Gynecologic Oncology Vol.21 No.3

Uterine corpus cancer has increased in prevalence in Korean women over the last decade. Recently, elegant studies have been reported from many institutes. To improve treatment strategies, a review of our own data is warranted. This work will discuss the risks and prognostic factors for uterine corpus cancer, and the radiologic evaluation,prediction of lymph node metastasis, systematic lymphadenectomy, minimally invasive surgery, ovarian-saving surgery, fertility-sparing treatment, and adjuvant treatment in women with uterine cancer.

Consumers’ Online Social Exclusion Experience on Conformity Consumption

정난희,박세범 서비스마케팅학회 2023 서비스마케팅저널 Vol.16 No.2

As social beings, humans have been forming various relationships, ranging from face-to-face interactions in the past to recent online interactions. Throughout these processes, consumers often encounter forms of social exclusion, such as rejection or exclusion from others. Especially with the recent prevalence of online interactions, social exclusion occurring on SNS, like making friends or commenting, is perceived as a factor threatening the fundamental human need for belongingness. In this context, we focus on the effects of social exclusion on consumption, particularly conformity consumption. Specifically, this research investigated the mediating role of perceived emptiness and the moderating role of social distance in the relationship between consumers’ online social exclusion experience and conformity consumption. We employed a 2 (social exclusion: exclusion vs. inclusion) × 2 (social distance: close vs. distant) between-subjects design. Results from a survey of 235 respondents showed that individuals who experienced social exclusion on Facebook were more likely to evaluate the possibility of engaging in conformity consumption higher than those who experienced social inclusion. Furthermore, individuals who experienced social exclusion online (vs. inclusion) rated their perceived emptiness higher and exhibited more conformity consumption. Lastly, individuals who experienced social exclusion on Facebook showed a higher intention to purchase products that their close friends (vs. distant friends) bought. This current research provides marketers with insights by maximizing the potential for conformity consumption among consumers who experience social exclusion in online advertising situations.
