This study conducts sentiment analysis to understand the meaning of the reviews recorded online after purchasing a product on OPTIMSM, and analyzes whether buyers feel satisfied or dissatisfied, thereby establishing a basis for product improvement and satisfaction enhancement. This was done for use as a reference material. To analyze online reviews, frequency analysis was measured through natural language processing using text mining techniques, and the most frequently mentioned words were compared using this. Next, polarity values for positive and negative reviews were obtained through sentiment analysis, and the influence relationship was identified through regression analysis of polarity values and satisfaction, which is the overall rating of Optimust given by customers who purchased Optimust. Through this analysis, it was shown how the polarity value of the review is related to the rating satisfaction of the overall optimust. As a result of the analysis, customer satisfaction with Optimust products was generally high. In particular, satisfaction with the function and effect of the product was high, and it was found that customers purchased and used the Optimust product to reduce joint pain, improve motor skills, and improve their quality of life. This allows companies to identify areas of greatest interest to their customers and focus on improving their products or services to increase customer satisfaction. In addition, companies will be able to identify customer dissatisfaction and establish strategies to address it.

The study included 120 subjects with borderline arthritis, and the dosage was 1,000 mg/day with measurements taken at 21 and 42 days

This study is to utilize consumers' 'consciousness' about products using brain reactions. In particular, the nerves of elderly consumers, which are physically functionally dull, can grasp the interests, preferences, and emotions of elderly consumers who respond to stimuli such as hearing, touch, and smell. Based on this information, the name, design, and performance of the product can be used to help provide customized products using brain response technology. Neuromarketing increases efficiency in a variety of areas. Color, image, and design ads that can awaken consciousness can help develop ads that can affect more effective message delivery and memory by analyzing consumers' brain responses and applying them to advertising strategies.

This study was conducted to examine the impact of a healing agricultural program utilizing rural resources on the tourism intention of middle-aged people. Based on previous research, a survey was conducted as a measurement tool, and each item was empirically analyzed through multiple regression analysis through reliability and validity analysis and factor analysis. As a result of analyzing the impact of the variables of the healing agricultural program on the tourism intention of middle-aged and older people, the order of animal healing, forest healing, plant healing, and food healing was found. This means that in order to increase overall tourism intention, intensive development of animal healing, forest healing, and plant healing programs is required. Additionally, in order for the healing agriculture program to increase tourism intention, it is necessary to raise the level of awareness of the healing agriculture program and promote healing agriculture. By developing and utilizing an educational program about the program, it was concluded that there was a willingness to recommend the healing agriculture program to people around them.

Since COVID-19, the number of people in need of physical and mental rest has increased, and activities that suit individuals' tastes are being conducted outdoors rather than indoors, and various studies on healing agricultural programs are being conducted. In this study, agricultural healing, animal-mediated healing, and horticultural healing programs were set as independent variables to find out the satisfaction and revisit intention of the healing agricultural program. 141 questionnaires were received from churches and office workers in Asan-si, Chungcheongnam-do, and used for empirical analysis. As a result of the analysis, first, touching animals was the best in animal healing, high, and crop processing experience was the best in agricultural healing, and gardening was the best in horticultural healing. According to the usage status, the cost was in the order of cost, program content, and value, and the cost was 30,000 won to 40,000 won (5 hours as of the 1st), which was the most preferred to participate in the agricultural healing program, and satisfaction and revisit intention were high. In the future, agricultural healing programs will be needed to further develop various and valuable programs and improve awareness levels.
