With the development of artificial intelligence technology, interest in data-based product preference estimation and personalized recommender systems is increasing. However, if the recommendation is not suitable, there is a risk that it may reduce the purchase intention of the customer and even extend to a huge financial loss due to the characteristics of the financial product. Therefore, developing a recommender system that comprehensively reflects customer characteristics and product preferences is very important for business performance creation and response to compliance issues. In the case of financial products, product preference is clearly divided according to individual investment propensity and risk aversion, so it is necessary to provide customized recommendation service by utilizing accumulated customer data. In addition to using these customer behavioral characteristics and transaction history data, we intend to solve the cold-start problem of the recommender system, including customer demographic information, asset information, and stock holding information. Therefore, this study found that the model proposed deep learning-based collaborative filtering by deriving customer latent preferences through characteristic information such as customer investment propensity, transaction history, and financial product information based on customer transaction log records was the best. Based on the customer's financial investment mechanism, this study is meaningful in developing a service that recommends a high-priority group by establishing a recommendation model that derives expected preferences for untraded financial products through financial product transaction data.

Attitudes about the ideal body are influenced by media, including fashion magazine advertisements. The purpose of our study was to analyze the ideal body image for males and females in contemporary society. We analyzed the contemporary ideal gender image through the examination of physical characteristics(body type, age), and fashion styles(hair, make up, supplements, clothing styles, body exposure) in fashion advertisements published in Gentlemen's Quarterly(GQ) and Vogue issued during 2002.

Based on the results above, this study proposes a few policy suggestions in the following areas: Improvement of competitiveness in trade-deficit service sector, achievement of the balance of profit and loss in goods and service sectors through the revision negotiation of the KORUS FTA, enhancement of competitiveness in competitive and comparative disadvantage items, reinforcement of ability to respond to consumption patterns in U.S. market, etc. in export-dominant items, and pursuit of horizontal-vertical division of labor in comparative advantage items and horizontal division of labor in comparative disadvantage items.

The current study aimed to explore the levels of consumers' perception for the PB apples which mainly sold in the large retailers, and then suggest the efficient marketing strategies for activating sales of the PB apples among the farm produce. The findings of the study revealed that the levels of the consumers' perception of value for the PB apples were influential on the brand credibility. In addition, the levels of the quality, perception of value, and brand credibility significantly affected the purchase intention. The image of the brand, however, did not show the effects on the brand credibility and purchase intention. Based on the study, in order to activate the brand for the local farm produce, the analysis results could suggest the four alternatives. Firstly, it is needed for the NB apples to be standardized and improved in terms of the qualities. Secondly, the more efficient ways to facilitate the purchases for the NB apples should be reconsidered in the emotional package. Thirdly, the levels of customers' perceptions for NB apples need to increase by providing them with convenient ways of purchases. Lastly, connecting consumers' groups with producers' groups could eventually enhance the brand credibility.
