Through the rapid developments in machine learning, there have been diverse utilization approaches not only in industrial fields but also in daily life. Implementations of machine learning on financial data, also have been of interest. Herein, we employ machine learning algorithms to store sales data and present future applications for fintech enterprises. We utilize diverse missing data processing methods to handle missing data and apply gradient boosting machine learning algorithms; XGBoost, LightGBM, CatBoost to predict the future revenue of individual stores. As a result, we found that using median imputation onto missing data with the appliance of the xgboost algorithm has the best accuracy. By employing the proposed method, fintech enterprises and customers can attain benefits. Stores can benefit by receiving financial assistance beforehand from fintech companies, while these corporations can benefit by offering financial support to these stores with low risk.

The Internet has been used as the academic researching purposes. Nowadays accordance with improving and being familiar with the World-Wide Web Many people are giving it a try to use the Internet as commerce markets. The noticeable example of internet-based use of the commerce is the Internet shopping mall. Using the WWW companies exhibit their products and users select the ones and take the payment for ones in the on-line Increasing the the Internet shopping mall there needs to be the countermeasure that companies and clients must verify each other. In this paper there are explained the development credit authentication system of the Internet shopping mall and the construction of the trusted environment clients can use Internet shopping mall. That is to develop the credit authentication system the credit-rating of Internet shopping mall can be sent securely and easily to clients and the information of credit-ranting cannot be eavesdropped.

중심시가지의 노후와와 교외개발의 메카니즘 속에서 일본의 중심시가지는 침체와 쇠퇴를 거듭하고 있으며, 이를 극복하기 위해 1998년부터 "중심 시가지에 대한 시가지 정비 개선 및 상업 등의 활성화의 일체적 주진에 관한 법률"에 근거하여 연간 1조엔의 예산을 편성하고 경제산업성등 관련 부처들과 TMO(Town Management Organization) 차원에서 총체적인 접근을 하고 있다. 이러한 중심상점가의 쇠퇴는 우리나라에서도 정도의 차이는 있지만 유사한 형태로 나타나고 있다. 이에 일본의 중심상점가를 살펴봄으로써 우리나라 주심상점가의 활성화 방향을 모색하는데 도움을 주고자 한다.

This research aims to design and analyze a ubiquitous customer relationship management system based on near field communication which can be applied to stores in off-line environment. The existing customer relationship management system has been used mainly for stores in off-line environment to issue a royalty card, to stamp a seal on the purchase goods, and to manage the history of customers' visits and purchases. But, the existing system has two weaknesses; it makes difficult for a store manger not only to acquire a wealth of customer data but also to systematically manage the acquired data. In particular, the effectiveness and efficiency of the royalty card are questioned when a customer makes purchases in the store in that the customer frequently does not carry it or loses it. So, this research suggests a ubiquitous customer relationship management system where a tag for near field communications is attached to a store in off-line environment; a store manager can collect and manage easily customer's dada and customers can seamlessly acquire store's information. To do this, this research conducts the followings. First, we review the previous researches of customer relationship management to examine the concept of ubiquitous customer relationship management. Second, from the examination, we draw the factors to be considered in ubiquitous customer relationship management system based on near field communication. Third, we propose a scenario where the suggested system is used. Fourth, we analyze the participants' values and the process that will be used for the suggested system. Finally, we discuss the possibility of the application of this system to real business environment from various viewpoints.

We have developed an algorithm to determine the position from the image points in a lensmeter with 6-sided prism lens. The positions of the image points which are formed by six prisms depends on the decenter position of a test lens and can be calculated by skew ray tracing. The optical characteristics of the lens meter was analyzed using the Code V program and the positions of the image points was expressed as a function of the decenter position of the test lens. By minimizing the expectation error, we can determine the decenter position position of a test lens from the image positions.

인터넷 쇼핑이 점차 대중화되어가면서 다양한 형태의 인터넷 쇼핑몰이 등장하고 있다. 현재 인터넷 쇼핑몰에 사용되는 상품이미지는 움직임이 없는 정적인 JPEG 이미지부터 빠르게 움직이는 동적인 GIF 이미지까지 다양한 형태를 이루고 있다. 이러한 상품이미지의 움직임 속도에 따라 사용자가 인지하는 쇼핑몰 사이트의 가격대와 상품의 가격대가 다를 것으로 예상했으며 사이트의 상품이미지의 지배적인 움직임 속도가 오프라인 상점을 연상하는데 영향을 미칠 것으로 추측하였다. 실험은 같은 상품 이미지를 동적인 움직임 정도에 따라 세 가지로 분류하여 사용자로 하여금 예상되는 쇼핑몰의 가격대를 매기도록 하였고, 어떤 오프라인 상점을 연상하는지 조사한 결과 사용자들은 정적인 상품 이미지를 사용하는 쇼핑몰 페이지를 고가의 인터넷 쇼핑몰로, 동적인 상품이미지를 사용하는 쇼핑몰 페이지를 저가의 인터넷 쇼핑몰로 인식하였다. 또한 상품 이미지의 움직임과 오프라인 상점의 가격대별 연상이 어느 정도 상관관계가 있는 것으로 밝혀졌다. 이 연구를 통해 동적인 상품이미지와 정적인 상품이미지가 쇼핑몰의 가격대인지 형성에 미치는 역할을 알아보고 가격 관련 사용자 경험에 시사하는 바를 살펴보았다.

It's a shame one of the famous places of Busan is the underground shopping area on the decline gradually. The reason why we developed this application is to provide information of the desired product and store for other residents as well as Busan residents. As a result, we expect a revival of underground shopping area. The main features of the application are to provide the location of shops and the information of products. In addition, it provides information of shops around me to utilize of location-based-service. We studied the possibility of win-win situation between offline stores and online through this application.
