Necessity of life insurance is stronger for people who feel some anxiety of their health. However, in fact, it is not permitted for them to get a contract, because life insurance stands on the mutual benefit system. Life insurance must be impartial to all applicants. However, it is very reasonable that an applicant, who has high medical impairment like heart infarction or cancer, is rejected, to have a contract by underwriting decision. On the other hand, if his medical impairment is not so severe, we might accept his application by giving some restriction. Numericalratingsystem by hunter-rogers gave us one of solutions to this problem. We can keep impartiality by using more restrictive decision, in order that we demand additional payment to the impairment applicant according to his mortality. We call this system as substandard life insurance. In this system we need detail information about impairments of applicants in order to decide the condition of substandard risks. Therefore, medical examiners are required to have high diagnostic technique.

Research on corporate bankruptcy prediction has been focused on financial information. Since the company's financial information is updated quarterly, there is a problem that timeliness is insufficient in predicting the possibility of a company's business closure in real time. Evaluated companies that want to improve this need a method of judging the soundness of a company that uses information other than financial information to judge the soundness of a target company. To this end, as information technology has made it easier to collect non-financial information about companies, research has been conducted to apply additional variables and various methodologies other than financial information to predict corporate bankruptcy. It has become an important research task to determine whether it has an effect. In this study, we examined the impact of electronic payment-related information, which constitutes non-financial information, when predicting the closure of business operators using electronic payment service and examined the difference in closure prediction accuracy according to the combination of financial and non-financial information. Specifically, three research models consisting of a financial information model, a non-financial information model, and a combined model were designed, and the closure prediction accuracy was confirmed with six algorithms including the Multi Layer Perceptron (MLP) algorithm. The model combining financial and non-financial information showed the highest prediction accuracy, followed by the non-financial information model and the financial information model in order. As for the prediction accuracy of business closure by algorithm, XGBoost showed the highest prediction accuracy among the six algorithms. As a result of examining the relative importance of a total of 87 variables used to predict business closure, it was confirmed that more than 70% of the top 20 variables that had a significant impact on the prediction of business closure were non-financial information. Through this, it was confirmed that electronic payment-related information of non-financial information is an important variable in predicting business closure, and the possibility of using non-financial information as an alternative to financial information was also examined. Based on this study, the importance of collecting and utilizing non-financial information as information that can predict business closure is recognized, and a plan to utilize it for corporate decision-making is also proposed.

As the conventional farming emphasizes the productivity and the quantity produced, large amount of agricultural chemicals have been used. As a result, natural environment and human health are critical issues in recent years in Korea. Reflecting these problems, many farmers have begun to practice the LISA(low input sustainable agriculture) voluntarily across the country. In this study, a survey was made to 13 apple producers who have been producing the fruits by practicing the LISA, and wanted to analyze the production and marketing information in order to suggest the improvement strategies for the sustainable agriculture. Some of the improvement strategies were suggested as follows ; First, advance payment to the LISA apple growers should be supplied in order to make it easier for the financially burdened producers. Also, some kind of means should be developed to prepare the equipments/machineries to make the organic fertilizers. Price differentiation should be utilized in marketing the products, and mass marketing channels for the LISA products should be provided for them. Public quality guaranty is badly needed in order to accelerate the marketing. Finally, stronger producer organizations should be organized and subsidized by the government because those organizations are playing an important role in developing the LISA.

Recently, we have been able to quickly order and pay with kiosks even at fast food restaurants, small private restaurants and cafes. However, people with disabilities who are uncomfortable with their arms and who are sitting in wheelchairs are difficult to use by pressing graphical buttons to use kiosks. Older people also feel uncomfortable to use kiosks because of their cognitive abilities to accept new information as they get older. In this paper, to solve this problem, we design and implement a order-payment system to add the voice command element of the AI speaker to the visual command element when the user interacts with the kiosk.

Agricultural environmental policies to reduce negative externalities and expand positive externalities became common around the world. However, literature regarding the efficient and effective implementation of agricultural environmental policies, such as optional direct payment, is limited. This study, thus, analyzes the relative importance for target selecting-criteria in order to enhance the cost-effectiveness of the Agricultural Environment Conservation Program in Korea. In this context, we conducted survey to 15 experts who are related in agricultural environment policies and analyzed survey results based on ANP method which can consider correlation between selecting criteria. The results show that, in the case field, "soil", "water", and "ecology" field have relative high importance than the other fields. Also, the relative importance for 'improving rural landscape', 'giving nutrient input moderately', and 'conserving agricultural heritage' activities is higher than the other activities. Furthermore, the relative importance among fields and activities of ANP is different from those of AHP. This result implies that it is necessary to consider the correlation between selecting criteria in order to design effectively. Finally, we suggest that in order to enhance the effectiveness of the program, it would be appropriate to assign differential points according to the importance of each activity when identifying appropriate farms.

This paper sees some legal phases of the forfaiting transactions performed by using bills of exchange (drafts) or promissory notes. It focuses on the issues of the endorsement without recourse and the aval under the Korean statute for such negotiable instruments which is enacted by succeeding to the Convention Providing a Uniform Law For Bills of Exchange and Promissory Notes (Geneva, 1930) of the League of Nations. This paper purposes to give basic legal guides for forfaiting participants in order for them to be able to prevent and solve some problems caused by lack of understanding for relevant rules of law. Forfaiting is a useful technic as it provides financing for international export businesses by enabling forfaiters to discount future payment obligations on non-recourse basis. It gives benefits to exporters by removing political, transfer and commercial risks of importers or their country. Also it protects exporters from the risks of the increase of interest rates and the fluctuation of exchange rate as well. In traditionally normal forfaiting transactions, exporter of goods generally takes promissory notes or accepted drafts from importers in payment for the price of goods. Further, when the exporter is not comfortable with the importer's credit or is not confident whether the importer will pay the accepted drafts or the promissory notes as they come due, the exporter nomally requires the importer to make the importer's bank (avalizer or guarantor) add an aval, which is made by the written expression of intention, the words of "per aval", and the guarantor's signature on the drafts or promissory notes. The exporter endorses without recourse to transfer the drafts or the promissory notes to the forfaiter, typically a bank, who purchases the drafts or the promissory notes without recourse.
