After sources of risks are identical and measured, a decision can be made as to how the risk should be handled. A pure risk that is not identical does not disappear ; the business merely loses the opportunity to consciously decide on the best technique for dealing with that risk. The process used to systematically manage risk exposures is known as risk management. Risk management is the logical process used by business firms and individuals to deal with their exposures to loss. It is a strategy of preloss planning for postloss resources. Besides, in the enterprise judiciary researches the textbook and the instance which relate risks, and reflects it to the written contract provision and various every manuel or holds seminar. It is a risk management which this talks generally. Here it stands but it becomes a problem the quality of type and countermeasure of risks. The purpose of this paper aims to explain adequate preventions to positively predict the risk this before being materialized, in practical section which is directly exposed to these risks in introducing international sale contracts(for example, the FOB and CIF contract) and the active management method of the risk which accompanys to the execution. And also analyzes the Lite-On case which relates with an international sale contracts.

As the supply method of products has become diverse and complex, problems such as manipulation of origin and product trace have occurred in the existing supply chain system. In order to deal with these issues, various Blockchain based studies have been actively carried in the SW industry and academy. However, there is a lack of comprehensive survey research on the applied Blockchain techniques, so that it hardly understand the pros and cons of the technologies. In this study, we intensively investigated the diverse studies from the Industrial and academic area based on the several criteria such as the goals, use of key Blockchain technologies, and IoT technologies.

This study was carried out to analyze terms in primary science textbooks. The results of the research are as follows. 1. The higher-grade science textbooks use more types of categories and less definitions for terms. Only 14% of definitions for terms are showed in textbooks, and no more than 0.4~0.6 definitions shows the shortage of definitions for terms in one class content. 2. The definitions by contract, which forms 68%, was the highest in elementary science textbooks. And the dictionary definitions, which are 62%, was the highest in experiment-observation textbooks. 3. The most used type of definitions is the way which is used for a case or a indicating methods, and its rate is increasing steadily. And its rate was 76% of the whole of terms. 4. Terms used in energy field are few as compared with terms of other fields. Each field has completely different ways of defining terms and presenting content in textbooks to other fields.

The advancement of ICT is changing every field of life. It becomes possible with the penetration of personalized devices, that is, smartphone. The boom of IoT will come when there exist diversified and personalized services. In general, we might admit that it is needed that the more privatized services than the overall serviced. Jeju Island is the only one special self-governing province in Republic of Korea and deserves to be proud of the unique culture from its long historical background. One of the very regional culture which performs by women divers, Haenyeo activity or culture, was registered as Intangible Cultural Heritage. When authors were researched Jeju Haenyeo as a worthy reserving service, we recognized that it has never considered to use any point of ICT/IoT yet. Because IoT holds the high potentiality to create any service scenario between interesting groups. We will design a few services for Haenyeo which covers their job territory or daily life, adopts up-to-date technology or method such as sensored network, smart contract and App/Web. In this paper, we intent to show the simplicity and easiness of the application of IoT not to much inconspicuous target. So, we suggest a specialized IoT service for the reservation and promotion of Haenyeo Culture. This service would be composed of sensors, IoT network and App/Web at home and office. This service can be used among interesting groups : Haenyeo, policy maker, manufacturer, service provider and culture consumer.

In insurance, the surrender rate is an important variable that threatens the sustainability of insurers and determines the profitability of the contract. Unlike other actuarial assumptions that determine the cash flow of an insurance contract, however, it is characterized by endogenous variables such as people's economic, social, and subjective decisions. Therefore, a microscopic approach is required to identify and analyze the factors that determine the lapse rate. Specifically, micro-level characteristics including the individual, demographic, microeconomic, and household characteristics of policyholders are necessary for the analysis. In this study, we select panel survey data of Korean Retirement Income Study (KReIS) with many diverse dimensions to determine which variables have a decisive effect on the lapse and apply the lasso regularized regression model to analyze it empirically. As the data contain many missing values, they are imputed using the random forest method. Among the household variables, we find that the non-existence of old dependents, the existence of young dependents, and employed family members increase the surrender rate. Among the individual variables, divorce, non-urban residential areas, apartment type of housing, non-ownership of homes, and bad relationship with siblings increase the lapse rate. Finally, among the financial variables, low income, low expenditure, the existence of children that incur child care expenditure, not expecting to bequest from spouse, not holding public health insurance, and expecting to benefit from a retirement pension increase the lapse rate. Some of these findings are consistent with those in the literature.
