In this paper, we propose a novel method for authenticating a user's personal-usage using a secure portable storage, so that the user carrying the secure portable storage is able to consume his/her own broadcast programs freely, regardless of the location of the devices. The proposed authentication process is performed by a portable personal-usage authentication device, an access-control module for the portable personal-usage authentication device, and a player integrating the access control module. The portable personal-usage authentication device plays a role of secure storage in which domain authentication information is securely stored, while the access-control module is in charge of accessing the authentication information and, consequently, acquiring a decryption key. The player decrypts the broadcast programs in real time and processes the decrypted media streams. In this Paper, we describe the structure and procedure of the proposed model, and verify its feasibility by implementation.

This study is an empirical research to analyze how many private income transfers in Korea decrease poverty rate, to compare the effects of private income transfers' decreasing poverty rate with income classes. This study has utilised the Family Income and Expenditure Survey to estimate the poverty ratio in urban areas and Unemployment Household Survey which Korea Institute for Health and Social Affairs has investigated at 1998. Majour findins are these. First, Sizes of private transfers incomes are much than that of public transfers incomes. The rates in receiving private transfers income are ten times higher than that in receiving public transfers income among urban worker's household. The mean of private transfer income are about six times larger than that of public transfer income among urban worker's household. Second, the effects of private income transfers' reducing poverty rates are not large. After private transfers, urbarn workers' households are about 10 per cent away from its poverty line, and unemploy households are only 3 per cent away from its poverty line. Third, especially, private income transfers are hardly reducing poverty rates among extreme poverty class. After private transfers, urban workers' households which their incomes are within low 5%, are not away from its poverty line at all.

Using data from Korea Welfare Panal Study(KWPS), this study examines the relationship between public income transfers and private income transfers in Korea. This research is analyzed by the procedure of OLS regression analysis. The results are as follows. First, the paper shows that public income transfers crowded out the private income transfers. Specially public assistance crowed out the private income transfers. The amount of public income transfers has negative correlation with the amount of private income transfers. The amount of public assistance income has negative correlation with the amount of private income transfers. But social insurance transfers do not have influence on the private income transfer. Second, the private income transfers in Korea are altruistically motivated.

The purpose of this article is to review the status of designation and preservation, management of national prehistoric sites and to suggest future applications. Prior to the discussion, the overall status of national prehistoric sites was reviewed. Specifically, the current status of designation, designated area, and distribution by region of national prehistoric sites according to the period and nature of the sites were examined in detail. Next, in order to understand the preservation and management of national prehistoric sites, I report the results of field trips to several sites, such as Geomdan-ri in Ulju, Songguk-ri in Buyeo, and Seoktaek-ri in Hongseong, and propose some measures for preservation, maintenance, and management of the remains. Finally, by referring to cases of US national historic sites such as protection, conservation, operation and management system and academic research project of cultural heritage, it is necessary to consider the need for a direction of the utilization that considers both socio-economic aspects as well as education and research on cultural heritage. The active use of cultural heritage can be a measure that leads to the continuous preservation and management of the sites, and ultimately will be a shortcut to increasing the value of national prehistoric sites.

대체로 만해연구는 그 연구방향에 따라 불교사적 연구, 민족운동사적 연구, 문학사적 연구의 세갈래로 나눠볼 수 있는데, 그 분포상 문학연구가 가장 대종을 이루는 반면 불교학적 연구는 아직까지 제일 미흡한 편이다.

This study analyzed private pension dependency of Korea and U.S. households using the most recent dataset of two countries. For this purpose, 2013 Korean Retirement and Income Study(KReIS) of national pension research institute in Korea and 2013 SCF(Survey of Consumer Finances) of FRB in U.S. were used. The private pension dependency was defined as the proportion of private pension wealth among total financial wealth in each household and tobit model was used to investigate determinants of private pension dependency of the two countries. After controlling for other factors, household income and net worth, age, educational attainment, and health status of householder were crucial determinants of private pension dependency for both countries. Householder's age, educational attainment, and health tend to increase the private pension dependency in Korea and U.S. However, household income and net worth affected the private pension dependency opposite direction. The private pension dependency increased with high level of income and net worth in Korea, while it decreased with high level of income and net worth in U.S. Results of this study provide useful implications for future pension system and policy in Korea.

This study was conducted to verify the mediation model of private self-consciousness on game addiction and aggression. Data from 439 boys were included in the analysis. The results are as follows. First, correlation analyses revealed that game addiction was positively correlated with aggression and private self-consciousness. Private self-consciousness was also positively correlated with aggression. Considering two factors of private self-consciousness, game addiction showed a significant positive correlation only with self-reflectiveness factor. Although two factors of private self-consciousness showed positive correlations with game addiction, regression analyses revealed that self-reflectiveness was the significant predictor of aggression. Second, the structural equation analyses showed that private self-consciousness, especially self-reflectiveness was found to partially mediate the influence of game addiction on aggression. Finally, limitations of this study and suggestions for further study were discussed.

유아론에 대한 비트겐슈타인의 철학적 투쟁을 조명하는 것은 그의 전체 철학의 핵심을 조명하는 것에 상당한다. 요컨대 유아론의 문제는 언어놀이, 놀이와 언어의 유사성, 가족 유사성, 규칙 따르기, 규칙 따르기의 역설, 사적 언어 논변, 뜻함, 봄과 -로서 봄, 모순, 논리적 필연성, 함 또는 실천과 같은 후기 비트겐슈타인의 핵심 개념이나 주제와 얽혀 있다. 이를 보이기 위해서 이 글에서는 유아론의 개념, 유아론에 대한 청년 비트겐슈타인의 생각, 후기 비트겐슈타인의 진단을 논의하게 될 것이다. 이러한 과정에서 우리는 비트겐슈타인이 유아론(넓게는 데카르트주의, 영국경험론, 현상학)에서 실천으로 나아가는 패러다임의 전환을 수행하고 있다는 것을 확인하게 될 것이다. 이러한 논의가 진행되면 우리는 유아론에 대한 후기 비트겐슈타인의 비판과 '사적 언어'가 어떻게 연결되는지 자연스럽게 문제 삼게 된다. 많은 학자들이 주장하는 바에 따르면, 비트겐슈타인은 사적 언어가 불가능하다고 간주했다. 그러나 나는 이러한 주장은 비트겐슈타인이 처한 패러다임의 전환 상황을 간과하는 처사로서 설득력 없는 것임을 보이고자 한다.

Using the 2001 Family Income and Expenditure Survey micro-data, this study analyses the anti-poverty effectiveness of public and private income transfers. In this study, the anti-poverty effectiveness of income transfers is summarized in two ways; 1) the poverty reduction effect of the income transfers, and 2) the poverty reduction efficiency of the income transfers. The poverty reduction effects are measured with several poverty indices including the head-count ratio, poverty gap, and Sen index. Using Beckerman's model, this study also analyses the poverty reduction efficiency of income transfers. This analysis documents substantial differences in the anti-poverty effectiveness of public and private income transfers. Although the private income transfers contribute more to reduce the head-count poverty ratio and Sen index than public income transfers, their differences are significantly reduced after the enactment of National Basic Livelihood Security Act. The results also reveal that the anti-poverty effectiveness of public and private income transfers vary by the types of families. In families headed by elderly and working aged, private income transfers have more anti-poverty effectiveness. But, public income transfers contribute more to reduce poverty than private income transfers among families headed by single adults with children. The results of this study suggest that recent changes in anti-poverty policies in Korea have been strengthened the Government's responsibility. And more importantly, to effectively reduce poverty among the poor families, anti-poverty polices must be designed to consider different family types.
