소비자 지각된 위험 인식과 자기조절동기가 위험감소행동에 미치는 영향
양윤철(Yoon Chul Yang),황용철(Yong Cheol Hwang) 제주대학교 관광과경영경제연구소 2018 産經論集 Vol.38 No.1
Purpose - This study aimed to figure out consumer perceived risks related to the purchase of OTC drugs, we will study whether there is a motivation motive through self-regulation focus to suggest implications for consumer OTC drug purchasing behavior. We also want to verify the impact of risk reduction behavior. Research design, data, and methodology - The present study’s research is performed on OTC drugs except ethical drug. Determinants for perceived risk, self-regulation focus and risk reduction behavior were selected from the determinants which were used in previous study; perceived risk is financial risk, time risk, psychological risk, and self-regulation focus is promotion focus, prevention focus, OTCs consumer’ risk reduction behavior is information search, brand loyalty, store loyalty. To verify the present research problem, survey was performed to consumers who the purchased OTC drugs in Jeju, Seoul, Gyeonggi-do and data were collected from total 300 subjects. SPSS 18.0, AMOS 18.0 program was used for data analysis based on the collected. Results - Based on these results, following principal can be established. First, when OTC drug buyers felt perceived risks, performance and time risk perceptions had a significant impact on the promotion focus motivation. Second, buyers with prevention focus motivation were highly perceived when monetary, performance, and psychological risks were highlighted. Third, buyers with promotion focus motivations were acting to achieve their desired results through more active information exploration, brand loyalty, and store loyalty in order to avoid perceived risks, while buyers with preventive focus motivation had no significant impact. Conclusions - It is necessary to convey a message that matches the marketing motivation of the pharmacy or pharmaceutical company with the buyer’s self-regulation focus motivation for the risk felt by consumers purchasing OTC drugs.

인지욕구와 중간 불일치 효과를 이용한 노스탤지어 마케팅의 전략적 활용에 관한 연구: 트로트 음악을 대상으로

Purpose: It's the heyday of trot. TV Chosun's trot program has changed the trend of the Korea music scene. The trot genre was the periphery of the Korea music scene. However, the trend in the Korea music scene has been replaced with the highest ratings of 35.71% for the "Tomorrow is Mr.Trot" program. The ratings on the general programming channel were phenomenal. This study extends the findings that recent trot success factors are due to the moderate incongruity effect. It is a study that confirms who the success of trot using the moderate incongruity effect was appealed to. Research design, data, and methodology: This study was conducted using experiments. 2 (need for cognition: low vs. high)×3 (nostalgia type: congruity vs. moderate incongruity vs. incongruity). The experimental design is a mixed experimental design. In the experiment, the manipulated variable is the nostalgia type. The stimulant used in the experiment is the trot song. The subjects are in their 40s or older. Results: This study suggested that the moderate incongruity effect of nostalgia is suitable for people with high need for cognition for those with high need for cognition, it was effective to approach nostalgia, which was consistent with expectations. Apart from the statistical significance, the difference of the evaluation was evident in congruity, moderate incongruity, incongruity. For those with low need for cognition, nostalgia who approached expectations as a moderate incongruity was the most effective. There was no difference between congruity and incongruity. Conclusions: Nostalgia is an area of emotion. The moderate incongruity effect is a rational area associated with the pursuit of novelty. The mechanism of moderate incongruity effect is to reject cliche and seek novelty. It showed the possibility of rational access to the nostalgia. The rational use of emotional nostalgia is the implication of this study.

고정층 반응기를 사용하여 상압에서 에탄올로부터 방향족화합물 제조에 관한 ZSM-5 제올라이트의 금속성분 및 실리카/알루미나 비의 영향을 고찰하였으며, 반응온도, 중량공간속도(WHSV), 반응물인 에탄올에 물 및 메탄올 첨가 영향도 검토하였다. 촉매로는 Si/Al2 비율이 23∼280 범위의 상용 ZSM-5에 Zn, La, Cu, Ga 성분을 함침시켜 촉매 활성 및 안전성 테스트에 사용하였다. 촉매의 특성분석을 위해 암모니아 승온탈착 실험(NH3-TPD)과 질소 흡-탈착실험을 수행하였다. 실험결과, 방향족화합물의 선택도에 관한 ZSM-5에 함침한 금속성분과 ZSM-5의 Si/Al2비에 크게 영향을 받았는데, 함침금속은 Zn-La > Zn > La > Cu > Ga 순으로 감소하였으며, ZSM-5의 적절한 산점을 가진 Si/Al2=50, 80에서 가장 우수하였다. 최적 반응온도(437℃)와 공간속도(0.8 h-1)에서 방향족화합물의 선택도는 초기 72%에서 30시간 이후 56%로 서서히 감소하는 경향을 나타내었다. The catalytic conversion of ethanol to aromatic compounds ETA was studied over ZSM-5 heterogeneous catalysts. The effect of reaction temperature, weight hourly space velocity (WHSV), and addition of water and methanol, which are the potential impurities of bio-ethanol, on the catalytic performance was investigated in a fixed bed reactor. Commercial ZSM-5 catalysts having different Si/Al2 ratios of 23 to 280 and modified ZSM-5 catalysts by addition of metal (Zn, La, Cu, and Ga) were used for the activity and stability tests in ETA reaction. The catalysts were characterized with ammonia temperature programmed desorption (NH3-TPD) and nitrogen adsorption-desorption techniques. The results of catalytic performance revealed that the optimal Si/Al2 ratio of ZSM-5 is about 50∼80 and the selectivity to aromatic compounds decreases in the order of Zn/La > Zn > La > Cu > Ga for the modified ZSM-5 catalysts. Among these catalysts from the ETA reaction, Zn-La/ZSM-5 showed the best catalytic performance for the ETA reaction. The selectivity to aromatic compounds was 72% initially and 56% after 30 h over the catalysts at reaction temperature of 437℃ and WHSV of 0.8 h-1.
