본 연구는 제품과 물리적 접촉이 불가능한 온라인 환경에서 다중 감각 단서가 소비자의 촉각적 심상과 제품에 대한 태도 및 구매 의사에 미치는 영향을 알아보고자 하였다. 실험 1에서는 참가자들을 음향 없이 사진만 제시한 조건, 음향 없이 영상만 제시한 조건, 일치하는 음향과 영상을 제시한 조건, 불일치하는 음향과 영상을 제시한 조건으로 나누어 제품을 탐색하게 하였고 그 후 촉각적 심상선명도, 제품 사용의 상상용이성, 제품에 대한 태도-구매 의사를 측정하였다. 그 결과, 모든 변수에서 불일치하는 음향과 영상이 주어진 조건이 가장 낮은 평균 점수를 보였다. 실험 2는 참가자 내 디자인으로 설계되어, 참가자들에게 동일한 제품을 실험 1과 같은 네 개의 조건에서 탐색하게 하였다. 탐색 후, 촉각적 심상선명도, 제품 사용의 상상용이성, 제품에 대한 태도-구매 의사, 접촉 욕구 등을 측정하였다. 접촉 욕구를 공변인으로 하는 반복측정 공분산분석 결과, 일치하는 음향과 영상을 제시한 조건은 다른 조건과 비교했을 때 유의미하게 심상선명도, 제품에 대한 태도, 제품 구매 의사가 높았다. 이중 매개 분석 결과, 다중 감각 단서 조건은 심상선명도와 제품 사용의 상상용이성을 순차적으로 매개하여 제품에 대한 태도-구매 의사를 유의미하게 예측했다. 결론적으로, 음향 및 영상 단서로 유발된 선명한 촉각적 심상은 소비자가 제품을 사용하는 상황의 상상을 쉽게 만들어 태도-구매 의사와 같은 의사 결정에 긍정적 영향을 미칠 수 있다. The purpose of this research was to determine whether multimodal cues in an online shopping environment could enhance tactile consumer mental imagery, purchase intentions, and attitudes towards an apparel product. One limitation of online retail is that consumers are unable to physically touch the items. However, as tactile information plays an important role in consumer decisions especially for apparel products, this study investigated the effects of multimodal cues on overcoming the lack of tactile stimuli. In experiment 1, to explore the product, the participants were randomly assigned to four conditions; picture only, video without sound, video with corresponding sound, and video with discordant sound; after which tactile mental imagery vividness, ease of imagination, attitude, and purchase intentions were measured. It was found that the video with discordant sound had the lowest average scores of all dependent variables. A within-participants design was used in experiment 2, in which all participants explored the same product in the four conditions in a random order. They were told that they were visiting four different brands on a price comparison web site. After the same variables as in experiment 1, including the need for touch, were measured, the repeated measures ANCOVA results revealed that compared to the other conditions, the video with the corresponding sound significantly enhanced tactile mental imagery vividness, attitude, and purchase intentions. However, the discordant condition had significantly lower attitudes and purchase intentions. The dual mediation analysis also revealed that the multimodal cue conditions significantly predicted attitudes and purchase intentions by sequentially mediating the imagery vividness and ease of imagination. In sum, vivid tactile mental imagery triggered using audio-visual stimuli could have a positive effect on consumer decision making by making it easier to imagine a situation where consumers could touch and use the product.

Purposes: Despite the positive health effects of both smokers and non-smokers, the non-smoking area policy is being negatively evaluated because of the vague fears of declining restaurant sales. The purpose of this study is to analyze the changes in sales of general restaurants(including liquor stores) and other restaurants that are considered to have the most applications of smoking cessation policy among the smoking facilities, and to examine the economic impact of the designation and expansion policies of non-smoking areas. Methodology: This study used the wholesale and retail trade survey data of the Korea National Statistical Office from 2011 to 2014 and analyzed 31,577 restaurants excluding missing values. For statistical analysis, t-test, ANOVA and Difference-in-differences(DID) models were used and the interaction term of area and year was entered. Findings: As the non-smoking area policy had been designated and expanded from December 2012 to December 31 2013, high restaurant sales in 2012 declined sharply in 2013. However, despite the expanding of the no-smoking area from January 1 2014 through December 31 2014, restaurant sales slightly recovered in 2014. In the case of other restaurants, there is no significant change in sales since the start of the policy in 2013. Practical Implications: The decline in restaurant sales due to the designation and expansion of non-smoking areas is temporary and can not be sustained over the long term. This result can be used to positively suggest negative perceptions of the designation and expansion policy of non-smoking areas. Also, this result can contribute to health promotion and smoking cessation policies by protecting non-smokers from the risk of secondhand smoking exposure and inducing smokers to decrease smoking rate and smoking amount.

The purpose of this study is to identify the effectiveness of outdoor exercise equipment which is the social welfare equipment by analyzing the changes in health related fitness and blood variables after the exercise program was carried out for 24 weeks by using outdoor exercise equipment with targets of the elderly. In order to achieve this goal, the elderly men and women living in K Gu at the age of 57-74 were selected as subjects and they were divided into an experimental group(EX-G, n=7; age, 66.6 ± 7.3 yrs; weight, 57.4 ± 6.1 kg; height, 166.3 ± 8.3 cm) and a control group(Con-G, n=7; age, 67.5 ± 4.5 yrs; weight, 61.8 ± 9.6 kg; height, 161.4 ± 8.9 cm). Outdoor exercise equipment program was carried out for 3 days/week and 60 min/day for 24 weeks. Changes in blood variables(glucose and total cholesterol in blood), health related fitness(muscular strength, muscular endurance, flexibility and cardiovascular endurance) were compared before and after experiment. Results of study showed that total cholesterol and blood glucose levels were decreased significantly in Ex-G after outdoor exercise equipment program was carried out(p<.05). It was shown that health related fitness factors were also significantly decreased in all items Ex-G(p<.05). In conclusion, outdoor exercise equipment program for 24 weeks could have a positive impact on health and physical strength of the elderly, and improvements on blood glucose and total cholesterol.

갑작스러운 사별은 남겨진 사람들의 심리적 고통을 높인다고 알려져 있다. 복합비애란 사별 이후 지속되는 병리적 애도 증상으로 자살과 같이 갑작스러운 상실을 경험할 때 발생 위험이 높다. OECD 국가 중 자살률이 가장 높은 우리나라에서 자살 사별자가 지속적으로 발생하고 있어 복합비애와 그로 인한 잠재적 자살 위험군의 증가가 우려된다. 그러나 아직 복합비애 연구는 국내에서 충분히 이루어지지 않았으며, 영향 요인에 대한 체계적 분석도 부족하다. 이에 본 연구는 국내 최초 전국 단위의 인구통계학적 특성을 반영하여 조사한 ‘사회적 관계 내에서 자살을 경험한 자살생존자의 정신건강 추적연구’ 1차년도 데이터를 기반으로 사별자를 추출하고(N=1,068), 복합비애에 영향을 미치는 인구통계학적 요인, 사별 특성 요인, 사망 요인에 대한 탐색적 연구를 실시했다. 사별자 연령이 높을수록, 고인의 사망 시점이 짧을수록, 생전 고인과의 교류 수준이 많을수록, 고인에 대한 주관적 친밀감이 높을수록 복합비애가 높게 나타났다. 고인의 사망 원인이 자살 사망일 경우, 갑작스러운 사망과 예상한 사망일 경우보다 복합비애에 더 많은 영향을 미쳤다. 이를 근거로 다양한 사회적 관계 내에서 자살을 비롯하여 사별 후 어려움을 겪는 사람들에 대한 실천적 개입 방안을 제언하였다. Sudden bereavement is known to increase the psychological distress of those left behind. Complicated grief is a set of symptoms of pathological mourning that persists after bereavement, and the risk of occurrence is high when experiencing sudden loss, such as suicide. In Korea, whose suicide rate is the highest among OECD countries, suicide survivors continue to occur, which raises concerns about complicated grief and their potential suicide risk. However, not much study has been conducted in Korea on complicated grief, and systematic analysis of influencing factors is lacking. Therefore, this study analyzed the data (N=1,068) of the 1st Wave of the Longitudinal Study of Suicide Survivors, using a nationwide stratified sampling method. An exploratory study was conducted on the factors affecting complicated grief. Higher complicated grief was associated with higher bereaved age, shorter time after death, higher level of interaction with the deceased, and higher emotional intimacy with the deceased. When the cause of death was suicide, it had a more significant effect on the complicated grief than other sudden and expected death. Based on these findings, clinical interventions were suggested for people who experience difficulties after bereavement, including suicide in social relationships.
