This paper is concerned with the statistical analysis and development of stochastic models for the demand for life insurance policy loans. For these, firstly the characteristics of the regression trend, periodicity and dependence of the monthly demand for life insurance policy loans are investigated by a statistical analysis of the monthly demand data for the years 1999 through 2008. Secondly, the causal relationships between the demand for life insurance policy loans and the economic variables including unemployment rate and inflation rate for the period are investigated. The results show that inflation rate is main factor influencing policy loan demands. The overall evidence, however, failed to establish unidirectional causality relationships between the demand series and the other variables under study. Finally, based on these, univariate time series model and transfer function model where the demand series is related to one input series are derived, respectively, for the prediction of the demand for life insurance policy loans. A statistical procedure for using the model to predict the demand for life insurance policy loans is also proposed.

Multiple life models are useful in multiple life insurance and multiple life annuities when the payment times of benets in these insurance products are contingent on the future life times of at least two people. A reverse mortgage is an annuity whose monthly payments terminate at the death time of the last survivor; however, actuaries have used female life table to calculate monthly payments of a reverse mortgage. This approach may overestimate monthly payments. This paper suggests a last-survivor life table rather than a female life table to avoid the overestimation of monthly payments. Next, this paper derives the distribution of the future life time of last survivor, and calculates the expected life times of male, female and last survivor. This paper calculates principal limits and monthly payments in cases of male life table, female life table and last-survivor life table, respectively. Some numerical examples are discussed.

Insurance accounting is the process of identifying, measuring, and communicating economic information to permit informed judgements and decisions by users of the insurance information. With the Korean-International Financial Reporting Standard(K-IFRS) on accounting for insurance contracts to be finalized by 2011 in Korea, the fair value accounting is expected to greatly affect the insurance industry in terms of insurance company' financial statements. This research analyzes the effect of financial statement as K-IFRS on the insurance accounting by comparing the financial statements of the listed company using past insurance accounting standard and the current K-IFRS standard. We analyzed the matched pair sample at loan amount, insurance contract debt, total assets amount, total debts amount, total capital amount in the financial statements of the listed 12 insurance company. We found that insurance contract debt, total assets amount, total debts amount, total capital amount are difference before and after K-IFRS applied insurance company.

정부는 건설현장에서 발생하는 다양한 형태의 불공정 관행을 개선하고 공정한 건설환경을 조성하기 위해 지난 6월 14일 '건설산업 불공정 거래관행 개선방안'을 발표했다. 개선방안은 하도급계약의 공정성을 높이기 위해 불공정 하도급계약을 무효화하고 발주자가 하도급계약을 의무적으로 점검토록 했다. 또한 건설하도급 외상매출채권 담보대출로 인한 하도급업체의 피해를 줄이기 위해 보험 보증 등을 통한 보호를 강화하는 방안도 담겼다. 이와함께 주계약자 공동도급 발주공사를 적극 발굴하여 원 하도급업체 간 수평적 협력관계 정착을 유도키로 했다. 정부의 이같은 개선방안은 그동안 대한설비건설협회가 정홍원 국무총리를 비롯하여 서승환 국토부 장관 등 관계부처와의 간담회와 관계요로에 수시로 건의한 결과 정부가 이를 적극 수용하여 마련된 것이다. 이로써 설비건설업계는 공공공사 분리발주 법제화와 함께 적극 추진하였던 주계약자 공동도급 활성화, 불공정하도급 관련 제도의 대폭적인 개선으로 경영환경이 크게 개선될 것으로 기대된다. 대한설비건설협회 김경회 총괄본부장은 "협회의 건의사항이 대폭 반영된 만큼 개선방안이 실효를 거둘 수 있도록 더욱 노력할 계획"이라고 밝혔다.

Blockchain technology began in 2008 when an unidentified person named Satoshi Nakamoto proposed a cryptocurrency called Bitcoin. Satoshi Nakamoto had distrust of the existing financial system and wanted to implement a financial system that is robust against hacking or mannipulation without a middleman such as a bank through blockchain technology. Satoshi proposed a blockchain as a technology to prevent the creation of the bitcoin and forging of transactions, and through this, the functions of issuance, transaction, and verification of currency were implemented. Since then, Ethereum, a cryptocurrency that can implement the smart contract on the blockchain, has been developed, allowing financial products that require complex contracts such as deposits, loans, insurance, and derivatives to be brought into the area of cryptocurrency. In addition, it is expanding the possibility of substituting products provided by financial institutions through combination with real assets. These applications are defined as Decentralized Finance (DeFi). This paper was prepared to understand the overall technical understanding of DeFi and to introduce the services currently in operation. First, the technologies and ecosystems that implement the overall DeFi are explained, and then the representative DeFi services are categorized by feature and described.
