This research is aimed at analyzing and understanding the perception and attitudes of inpatients in a general hospital in Seoul towards the activation of private health insurance. Survey was conducted against 231 inpatients, results of which were analyzed in the methods of frequency analysis, chi square test, and logistic regression. The results are summarized as follows; First, better-educated population who finished college education at least, higher-income population, and people who had more knowledge about private health insurance showed more perception about activation of private health insurance. Second, better-educated population who finished college education at least, higher-income population, those who are insured in existing private insurance, oncological patients, and people who had more knowledge about private health insurance showed more positive attitude towards private health insurance paying for actual damages, long-term care insurance, and income security insurance. Third, age and education were the factors affecting perception about activation of private health insurance. The older the age is, perception was 1.035 times positive towards activation of private health insurance, and those who finished college education or above showed 3.148 times positive perception towards the same. Forth, surgical patients showed 1.087 times more positive attitude towards private health insurance paying for actual damages than internal medicine patients, while oncological patients showed 2.314 times more positive attitude than internal medicine patients. Further, understanding on the activation of private health insurance was 6.014 times higher in the higher understanding group than in the lower understanding group. Intention to use long-term care insurance was 2.692 times stronger in the male group than in the female group, and 3.616 times stronger in the oncological patients group than in internal medicine patients group. Further, understanding on the activation of private health insurance was 3.881 times deeper in the higher understanding group than in the lower understanding group. Intention to use income security insurance was 3.185 times stronger in those who have academic background of under the high school than those over the college, and 4.175 times higher in the group those whose monthly average income is over 4 million won than those under 4 million won. Also, intention to use income security insurance was 4.323 times higher in the group those who are insured by existing private insurances than those who are not insured by those insurances and it was 5.234 times higher in the group of oncological patients than in the group of internal medicine patients. Further, intention to use income security insurance was 3.559 times higher in the group those who thought that out-of-pocket money of the National Health Insurance is too much to bear than those it is quite endurable. Understanding on the activation of private health insurance was 4.875 times deeper in the higher understanding group than in the lower understanding group. There were some suggestions could be made based on the results of this research. First, reinforced publicity and education is needed for the low-educated or low-income group, as there are gaps in the understanding on the activation of private health insurance depending on the degree of education and income. Second, government should prepare administrative complementary measures to solve the problem of adverse selection by the consumer which is foreseen when private health insurances are activated. Third, government should suggest the desirable course of development of private health insurance items to ensure efficient use of enormous fund of private insurance market for health security of the people. Further, institutional complementary measures are needed to convert existing cancer insurances or specific disease insurances to private health insurances paying for actual damages guaranteeing against every kind of disease. Forth, it judged that, not only private health insurances paying for actual damages, but also long-term care insurances and income security insurances are prospective as fields to create fresh demand for insurance industry.

The aim of the study is to implement a factor analysis of the determinants of pricing in a state-regulated competitive market using economic and mathematical modelling methods and to develop ways to improve the pricing environment of the market under study. The purpose of the work defines the main objectives: (i) to investigate the features of the competitive model of the Ukrainian flour market; (ii) to analyse the current price conjuncture of the flour market and the dynamics of the main determinants of pricing; (iii)to develop ways of improving the price situation on the flour market on the basis of the factor analysis on the results of economic and mathematical modelling. In order to ensure the reliability and validity of the research results, the following methods were applied: the logical-dialectical method of scientific knowledge in the study of the main theoretical aspects of flour market functioning, the method of logical generalisation and synthesis, comparison, factor analysis, correlation and regression analysis, the graphical method, etc. It has been shown that pricing in a state-regulated competitive market has its own characteristics. For example, in the flour market the price of goods cannot be influenced by producers (sellers) by any methods, therefore determinants of pricing by indirect influence have been taken into account. The five-factor power model of wheat flour price has been constructed. It was substantiated that the price of wheat flour in Ukraine is mostly influenced by consumer price index (0.92 %). The received complex model of wheat flour price may be used also for medium-term forecasting and working out the ways of price formation optimization in the flour market.

The security of data and information using encryption algorithms is becoming increasingly important in today's world of digital data transmission over unsecured wired and wireless communication channels. Hybrid encryption techniques combine both symmetric and asymmetric encryption methods and provide more security than public or private key encryption models. Currently, there are many techniques on the market that use a combination of cryptographic algorithms and claim to provide higher data security. Many hybrid algorithms have failed to satisfy customers in securing data and cannot prevent all types of security threats. To improve the security of digital data, it is essential to develop novel and resilient security systems as it is inevitable in the digital era. The proposed hybrid algorithm is a combination of the well-known RSA algorithm and a simple symmetric key (SSK) algorithm. The aim of this study is to develop a better encryption method using RSA and a newly proposed symmetric SSK algorithm. We believe that the proposed hybrid cryptographic algorithm provides more security and privacy.

현재 우리나라에서는 민간조사(Private Investigation)의 도입에 대한 다양한 논의들이 행해지고 있다. 그런데 이러한 논의의 핵심 중 하나가 민간조사원의 교육에 관한 것이다. 민간조사원의 교육은 국민의 생명과 재산의 보호와 관련된 것을 주요 업무로 하고 있기 때문에 일반적인 교육과는 달리 전문성과 윤리성을 강하게 요구한다. 그러므로 민간조사원의 전문성과 윤리성을 뒷받침하기위해 체계적인 교육프로그램이 마련되어져야 한다는 것은 당연하다고 할 수 있다. 그러므로 본 연구에서는 민간조사업 관련자들과의 심층면담을 통해 이들이 민간조사 교육을 대학교육에 포함시키는 방안에 대하여 어떻게 생각하는지를 탐색적으로 조사한 후 수집된 자료를 질적 자료분석 프로그램인 NVivo 2를 활용하여 분석하였다. 연구결과, 민간조사가 필요한 이유로는 국가치안인력의 부족과 경찰이 중요한 사건이 아닐 경우 민원인의 피해에 대해서 적극적으로 개입하지 않는 것, 그리고 공권력을 행사하는 경찰관의 신분으로 민사문제에 개입할 수 없는 것이 가장 큰 이유로 나타났다. 그리고 민간조사학과 개설 필요성으로는 전문교육기관의 부재와 경찰 또는 의뢰인으로부터의 민간 조사에 대한 신뢰성 증대가 가장 큰 것으로 드러났다. 민간조사학과의 전망과 진로방향에 대해 연구 참여자들은 크게 "공인민간조사업법"안의 통과 전과 통과 후로 나뉘어 졌다. 법안의 통과 전은 현재와 같이 민간조사와 유사한 보험회사 조사업무, 외국 민간조사업체, 국내 컨설팅 업체, 경호보안업체로 진출하게 될 것이라고 하였고, 법안이 통과되면 이와 더불어 현재의 경비법인과 같은 민간조사법인이 다수 등장하게 될 것으로 전망하여 법안 통과 시 민간조사학과가 활성화될 것이라 판단하였다.

This paper attempts to analyze the early retirement in the OECD countries and discuss implication of that in the old age policy in Korea. The increase of the early retirement in the almost all OECD countries is a common fact. Especially the rate of early retirement rapidly increased in the 1980s, mostly reflecting the high rate of unemployment and states' policies to reduce it. However, it varies across countries: the unemployment compensation pathway in France, the mixture of social assistance and private insurance in England, VUT in Netherland, the privatization of the early retirement in the U. S., and partial retirement and labor market policy in Sweden. The early retirement in the advanced countries contributes to de-institutionalization and de-standardization in life course model. It resulted in the erosion of the ordinary conception that the retirement was the beginning of the old age. And the last phase of life course became blurred. With respect to the problem of the early retirement, there is a big difference between Korea and the OECD countries. Above all, the retirement age is 55 years in many companies and the public pension is not universalized in Korea. Accordingly the policy for income security of the old age in Korea should be connected with social security policy such as the gradual extension of the retirement age and the expansion of the public pension and labor market policy such as job training for the old age, transformation of the seniority wage system etc.
