The purpose of this study was to evaluate the financial status of single mother households by financial ratios. Data was drawn from Labor Panel Survey Data in 1999, and 198 single mother households were selected. Major findings were as follows: 1) The levels of after-tax income, income per person, expenditure, expenditure per person, asset, pure asset, and debt of single mother households were lower than their counter-parts. 2) All financial ratios showed that both financial security and financial growth of single mother households were lower than their counter-parts. Especially, 22% of single mother households had the lower level of income that the lowest cost of living.

The purpose of this study was to compare the financial status between Aged Households and Non-aged households. The sample obtained from 1993 KHPS, consisted of 3,425 Korean married couples including 2,915 of non-aged households and 510 aged households. Statistics employed for the analysis were frequencies percentile and t-test And Lorenz curve and Gini coefficient were used to compare the financial status of two groups. The results of this study were as follows. First financial status of aged households specially annual total income annual current income earned income and annual total expenditure were lower than those of non-aged households. Second Gini-coefficients of aged households' income and expenditure were greater than expenditure of them. Moreover Gini-coefficients of aged households' total asset and total debt were greater than those of non-aged households' However total asset of aged and non-aged households were smaller than total debt of two groups.

This study attempted to investigate the factors affecting financial status of the rural middle-aged and old-aged household. The results shelved that the significant variables which influenced on the probability of financial security measured by consumption to income ratio were sex and education level of the household head, family size, total income, total expenditure and total assets. The most influential variables on the probability of financial security measured by liquidity ratio was liquid assets, and total assets. Education level of the household head. liquid assets, total assets, and total debt had significant effects on the probability of financial security estimated by debt burden ratio. Among the economic variables, only liquid asset had significant negative effects on the probability of financial security assessed by the capital stock ratio.

STM-1 체계의 광통신 수신부 광모듈에 내장하기 위한 155.52 Mbps 리시버 ASIC을 0.65 ㎛ 실리콘 CMOS 기술을 이용하여 설계 제작하였다. 재작된 ASIC은 155.52 Mbps 데이터신호 재정형을 위한 제한 증폭기와 155.52 MHz 클럭을 추출하기 위한 클럭 추출 회로를 주축으로 구성되어 있다. 또한 이 리시버는 전원이 켜지는 초기 동사 상태에서나 동작 도중 데이터신호가 입력되지 않더라도 155.52 MHz 부근의 클럭주파수를 유지하여 항상 안정된 동작을 할 수 있게 하기 위한 수렴 보조 회로 및 LOS 감지 회로도 내장하고 있다. 측정 결과 설계된 리시버는 1 mV- 1 V의 넓은 입력 전압에 걸쳐 데이터 재정형이 이루어지며, 155.52 MHz의 안정된 클럭을 추출하고 있음을 알 수 있었다.

This study examines the housing-related characteristics of unmarried youth using occupational history data from the 10th-14th (2016-2020) youth panel (YP2007) of the Korea Employment Information Service, and the characteristics of housing and employment. Their effect on marriage intention was empirically analyzed. The results of the analysis show that highly educated people, high-wage workers, household heads or economically independent young people, and young people in good financial conditions have a high willingness to marry. Their economic conditions are very important factors. Among the young employed who have become economically independent from their parents, full-time permanent workers, workers at large corporations, and highly waged youth showed a strong desire to get married. On the contrary, young people who are insecure temporary/daily workers, workers at small firms, and low-wage workers show a low willingness to marry. In conclusion, the results imply that young people who are in a vulnerable state in the labor market are giving up or delaying their marriage. Therefore, it is necessary to enhance policies to provide better employment opportunities for youth and, simultaneously, revamp the policy measures to enhance housing conditions.

In this paper the normalized innovations squared of a Kalman filter is used to detect a bias level in prediction errors due to target accelerations. The probability density function of the normalized innovation squared is obtained for a steady state Kalman filter, and it is used to calculate the detection probability of the bias level. A typical example is given to compute the detection probability and to plot the maneuver detector operating characteristic curves.

The purpose of this study is to analyze 3 pilot developments, collectively known as the NYCHA Infill Development, in the Bronx, Brooklyn and NYC, as a case study focusing on the characteristics of the business structure to enhance the public good by ensuring the provision of more affordable housing within the developments. As part of the "Next Generation NYCHA" macroscopic housing policy in NYC, this case is considered to respond to the crisis of affordable housing that reflects the domestic situation. The results of this study may have implications for domestic housing problems. Moreover, it may help to provide diverse methodologies applicable to public housing development.

The paper aims to estimate the external effects of mountaineering on medical expenses within national economy. Though there is no difference in the participation ratio of mountaineering among sexes or income levels, the ratio of the elderly is higher than that of younger. The medical expenses have negative correlation with mountain climbing times and climbing frequencies, but this correlation is insignificant statistically. Without mountaineering, the medical expenses of Korea would increase by 2.8 trillion Won (4.6%). Therefore the policy to support usual mountaineering must save the medical expenses more than other policies. and the increase of public expenditure on mountaineering can decrease the deficit of government budget through the positive external effects on national medical expenses.

OSPF is the optimized routing protocol in wired network and considered as a tactical routing protocol in wireless tactical communication network. However because it is designed basically based on wired environment, it runs inadequately in wireless tactical environment: noise and jamming signal. So, we proposed new OSPF cost function to develop active routing protocol in wireless tactical communication network. In redefined cost function, there are four parameters that are relative transmission speed, link weight, router utilization, link average BER(Bit Error Rate). These parameters reflect wireless tactical characters. Also, we remodel the option field in Hello packet. It can help user to periodically check the link state. From the simulation result, it is shown that proposed OSPF is better than OSPF in jamming situation and has accumulative delay gain with dispersion of traffic load in entire network.
