The volume of insurance business of Korea is now ranked 6th in the world. In spite of the rapid growth of the volume of the Korean insurance market, the growth of quality and technology of Korean insurance business has not reached on the top position. And the role of actuaries in Korea does not come up to the standard of the advanced economies due to the total lack of good actuarial science programs in Korea. In this paper, we consider a few desirable actuarial science programs for both undergraduate and graduate level and show concrete examples of curriculums useful in Korean universities. The curriculums are designed to help students to pass the four exams of Society of Actuaries and Casualty Actuarial Society and to get credits for Validation by Educational Experience (VEE). At the same time our curriculums can cover the contents of Korean actuarial exams. We also consider the actuarial internship programs.

This study aims to investigate the presence/absence of subjects in the area of finance insurance sector in the past and corresponding areas of the courses in accordance with the reform of Korean school mathematics curriculum. In addition, the study had analyzed the linkage to the curriculum of the subjects for the Junior High, and High School in accordance with the school mathematics as mathematical knowledge base. As the results of this study, it was identified that the knowledge of mathematical contents addressed in the school mathematics education had a very high connectivity as basic mathematical knowledge to understand and utilize high level of the insurance mathematics required for the job performance in the finance insurance sector.

This paper evaluates the performance of various distribution assumptions in regression settings for estimating insurance loss. The gamma distribution is commonly used to handle the asymmetry property of loss distribution. However, recent studies highlight the significance of heavy-tailedness in loss distribution. Through an analysis of real home fire insurance data, we compare the effectiveness of different distribution assumptions in regression methods. Our findings show that the choice of parametric distributional assumption is crucial in determining premiums for various insurance products, including "excess of loss insurance" and "limit insurance". Additionally, we discuss practical considerations for applying our results in home fire insurance.

In 1876, America's first Jewish math professor J. J. Sylvester took a department head position at the first research university in USA at the age of 61. He launched the America's first research journal of mathematics in 1877. We study the role and meaning of J. J. Sylvester, F. Klein and E. H. Moore in late 19th century of American mathematics from Korean's perspective.

다자간 프라이버시보호 교집합 연산은 둘 이상의 참여자들이 서로 자신이 가지고 있는 데이터를 노출시키지 않으면서 교집합을 구하는 문제이다. 다자간 프라이버시보호 교집합 연산은 보험사기 방지시스템, 항공기 탑승 금지자 목록 검색, 의료 정보 검색, 전자투표 등에서 이용될 수 있다. 2009년 Hazay와 Lindell[1]은 스마트카드를 이용한 양자간 프라이버시보호 교집합 연산을 하는 프로토콜을 제안하였다. 이 프로토콜은 신뢰할 수 있는 제 3자를 설정할 수 없는 상황에서 스마트카드의 보안 요소를 사용하여 양자간 프라이버시보호 교집합 연산을 할 수 있다. 또한 이론적으로는 안전하나 실제로 구현이 어려운 일방향함수를 기반으로 한 모델의 단점을 의사난수치환을 사용하여 현실적인 모델로 보완하였다. 본 논문에서는 기존의 Hazay와 Lindell의 양자간 프로토콜에 Commodity Server를 도입하여, 다자간 프라이버시보호 교집합 연산을 할 수 있는 프로토콜을 제안한다.

In this paper, In this paper, we study the recognition of undergraduate students and professors about the relation between mathematics learning contents of high school liberal arts course and major fields of college of business administration. We chose 155 undergraduate students and 6 professors at college of business administration in M university and investigate their recognition about the relation between mathematics learning contents of high school liberal arts course and major fields of college of business administration. We found following facts. First, mathematics education in high school should be based on understanding of mathematical conceptions and principles rather than problem-solving skills to intensifying the relation between mathematics of high school liberal arts course and major fields of college of business administration. Second, we have impressed upon them, whom are going to college of business administration, the need for more mathematics to study a major field.

Objectives: People are living longer, but often with diseases or chronic conditions. As a consequence, interest in resolving insurance blind spots is growing. This study provides substandard risk-relevant statistics to help substandard risks who are likely to fall in insurance blind spots obtain insurance coverage, such as the reimbursement of medical costs, as well as to stimulate insurance product development. Methods: This study uses National Health Insurance Service (NHIS) cohort data to determine the relevant statistics. The incidence rates of severe diseases are derived and compared against standard risks to establish a set of relative risk factors. These incidence rates of standard and substandard risks are then compared. Results: Currently, an individual's cancer history is used in the underwriting process for simplified issue insurance. However, underwriting focusing on hospitalization and procedures related to serious illnesses could lower premiums for substandard risks. Moreover, the statistical results could be used to expand the coverage of health insurance products. Conclusions: This study's relative risk factors can be used to derive simplified issue premium rates for substandard risks. They can also be used to implement discount and loading schemes for medical reimbursement insurance and help insurance companies implement proactive risk management.

On roads vehicles are the bossy, while pedestrians are the frangible. The current paper has a purpose for contributing to pedestrian's safety. First, it studies the association between demographic parameters and TPB(Theory of Planned Behavior)'s variables(pedestrian's attitude toward crossing behavior in roads, personal norm, etc.) and his/her crossing intention, perceived risk while crossing, and the experience of past traffic accidents. Its sample comes from a specific population(college students). Further, the present study endeavors to explain the portion of human cognitive failure/error, impulsiveness, time perspective, and probabilistic/math-logical judgment ability in pedestrian's riky crossings on roads. Research results found that TPB variables and such a few human characteristics have some significant association with the risky crossing intention on the road. Considering the human psychological portion in pedestrian accidents would help us prevent the accidents and reduce unhappiness of the accidents and, further, economic loss and insurance expenditure related with the accidents.

In the recent years there has been an increase of service competition in the activity of product selling, especially in the extension of warranty coverage and qualify. The variables in connection with the service competition are not crisp, and required the expertise of the production line. It thus becomes all the more necessary to use subtler tools as decision supports. These problems are typical not only of product companies but also of financial organizations, credit institutions, insurance, which need predictions of credibility for firms or persons in which they have any kind of interest. A suitable approach for minimizing the risk is to use a knowledge-based system. Most often expert systems are not standalone programs, but are embedded into a larger application. The aim of this paper is to discuss an approach for developing an embedded fuzzy expert system with respect to the product selling policy, especially to present the decision system of automobile selling activity around the extension of warranty coverage and quality. We use the MATLAB tools which integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Also, we present the API functions embedding into the existing application.
