We investigated multi-layer perceptrons and supervised learning algorithms, and also examined how to model functional relationships between covariates and response variables using a package called neuralnet. The algorithm applied in this paper is characterized by continuous adjustment of the weights, which are parameters to minimize the error function based on the comparison between the actual and predicted values of the response variable. In the neuralnet package, the activation and error functions can be appropriately selected according to the given situation, and the remaining parameters can be set as default values. As a result of using the neuralnet package for the infertility data, we found that age has little influence on infertility among the four independent variables. In addition, the weight of the neural network takes various values from -751.6 to 7.25, and the intercepts of the first hidden layer are -92.6 and 7.25, and the weights for the covariates age, parity, induced, and spontaneous to the first hidden neuron are identified as 3.17, -5.20, -36.82, and –751.6.

In order to suggest the factors to be managed for customer satisfaction management in the franchise hair salon industry, a survey was conducted on the customers' experiences toward consumers who have experience using domestic franchise hair shop service in Korea. An online survey was conducted for 1,000 consumers who had used the top five franchise hair salon services within 6 months of the survey. According to the result of research on service quality(SERVQUAL)’s 5 factors- tangibleness, responsiveness, assurance, reliability, and empathy, assurance has the greatest impact on satisfaction, followed by responsiveness, empathy, reliability, and tangibleness. The service quality satisfaction of the five companies surveyed was 3.77 out of 5, indicating that there is much room for future satisfaction. This study aims to provide information on which factors should be invested more with limited resources to improve customer satisfaction.

The study aims to examine the connection between psychology in human unconsciousness and color, after looking at the meaning and symbolism of the characteristics and colors in Klimt’s paintings from an analytical psychological point of view, Gustaf Jung’s archetype theory. After analyzing Jung’s archetype theory, First, in Klimt's paintings, the gold and yellow colorful decorations and patterns expressed desire with unconsciousness, sex, and especially a woman’s desire for sex. The physical relationship between men and women is described as eros, life, and death. Second, the main colors in the paintings were blue, black green, gold, yellow, and orange, indicating anger and oppression, passion, desire, hope, and eroticism, and orange and yellow colors represented the inner healing colors of hope. Third, the artist's inner healing process contains color for himself and incorporates the inner unconsciousness and consciousness. The colors expressed in paintings are not only therapeutic meaning but also being conscious of inner unconsciousness, which is valuable as healing. Therefore, the color will be useful as a means of conveying psychological expression in the psychological counseling sessions.
