  • This study examines regression modeling method using zero-inflated distribution in relation to estimation of exposure distribution required in advertisement media planning. Exposure distribution is the percentage of audiences that are exposed each time the ad is repeated. Such an exposure distribution plays a very important role in providing basic information necessary for calculating various indicators for quantitatively measuring the advertising effect. Especially, due to the decrease of advertising price and the spread of various media, the frequency of the advertisement or the broadcasting of specific advertisements has been greatly increased compared to the past. As a result, the frequency of exposure is relatively decreasing. In this situation, the number of individuals who are not exposed to the media, that is, are not exposed to advertising structurally is increasing. This research proposes advertising exposure distribution models using a zero-inflated regression model, and conducts a comparative study using actual cases.

Methods : Evaluated the result of Cathami Flos herbal acupuncture treatment twice in a week for patients who have cervical headache with cervical MRI abnormality at Gun-Po Oriental medical hospital in affiliation with wonkwang university. Results : 1. In the distribution of sex; Female rate was 45.9% and male rate was 54.1%., In the distribution of age, Thirties and forties group was the largest group by each 32.8%. 2. In the distribution of Cervical MRI abnormality; Abnormality of C2/3, C3/4, C4/5 was 94.6%, disk bulging and disk protrusion was 94.5%. 3. The effect of treatment by age was as follows; Thirties and forties group were each 31.1%, total 62.2%. 4. In the distribution of treatment period and curative value; 'Two weeks to four week' was 63.9%. Conclusion : These results shows that it is possible for headache to be occurred by cervical abnormality and that the effect of treatment by Cathami Flos herbal acupuncture is exellent by relaxing contracted muscles, strengthening weakened' ligaments and improving inflammatory parts.

  • Purpose: As one of the continuous studies on the offline distribution industry, the purpose of this study is to find ways for offline stores to respond to the growth of online shopping by identifying research trends on department stores. Research design, data and methodology: To this end, this study conducted word frequency analysis, word co-occurrence frequency analysis, BERTopic, LDA, and dynamic topic modeling using Python 3.7 on a total of 551 English abstracts searched with the keyword 'department store' in scienceON as of October 10, 2022. Results: The results of word frequency analysis and co-occurrence frequency analysis revealed that research related to department stores frequently focuses on factors such as customers, consumers, products, satisfaction, services, and quality. BERTopic and LDA analyses identified five topics, including 'store image,' with 'shopping information' showing relatively high interest, while 'sales systems' were observed to have relatively lower interest. Conclusions: Based on the results of this study, it was concluded that research related to department stores has so far been conducted in a limited scope, and it is insufficient to provide clues for department stores to secure competitiveness against online platforms. Therefore, it is suggested that additional research be conducted on topics such as the true role of department stores in the retail industry, consumer reinterpretation, customer value and lifetime value, department stores as future retail spaces, ethical management, and transparent ESG management.
