This study explores a changing social expenditure structure of welfare states on new social risks, using logistic regression analysis with Panel Corrected Standard Errors Model on panel data of 1997-2007 years from 27 OECD nations. The result of this study presents that social expenditure structures have been adjusted with new social risk structure due to trade openness, female employment rates, and child population rates. Greater trade openness, higher women's employment rates, and lower child population rates are, more social investment expenditures are than income security expenditures. Rates of employment in service industries and elderly population rates are not statistically significant on the change of social expenditure structure. This result does not imply a complete switch from demand-based to supply-based social policy, but somewhat reflects transitions of a social welfare system for changing economic and social environments in order to sustain welfare state economically.

In recent years, the knowledge service industry is getting much attention in terms of the role as new growth driver and employment creation sector whereas the overall potential growth rate in Korea has been slowed due to reduced investment and employment in manufacturing sector. This study examines how the knowledge service industry contributes to economic development and employment creation by analyzing the structure transition pattern of the knowledge service industry from 1995 to 2010 and suggests, based on these results, some policy implications for the industry's development. It turns out that the knowledge service industry greatly contributes to total production increase and employment creation during the period of 1995 to 2010. Special strategy for increase in labor productivity will be required for the knowledge service industry to contribute consistently as growth driver and employment creation sector since production increase rate and growth contribution level have been gradually decreased while employment growth rate and its contribution level have been consistently increased in the knowledge service industry.

The Correlations Between the Labour Market Structure and Poverty of the Regions The main objectives of this study are to make an investigation into the spatial characteristics of poverty and to analyze the effects of regional labour market structure. Most previous studies on poverty were more likely to examine internal factors like the characteristics of poor households or family structures than external factors in terms of the regional environments. In order to achieve these goals, this study used the Small Area Estimation designed to estimate the income of each household and then calculate the poverty rate of each local area in order to examine the spatial characteristics of poverty. The poverty distribution in Korea showed the local labour market structures effect on the region poverty rate. The Korean economy now exhibits a big gap between the haves and the have-nots and between urban areas and rural areas. The poverty rate of particular regions will increase and those in the areas will face deteriorated circumstances falling into poverty traps. This study reflects this stern reality and empirically proved the strong need for consideration of regional characteristics in conducting studies on poverty and related policy amendments.

This paper attempts to account for the recent decline in the share of 'regular employees' among total employees. It finds, among other things, that the decline which began in 1993 is not associated with the changes in the composition of the worker groups that have differing tendency to work as regular employees. Overall, the decline in the share of regular employment is mainly due to the workers' increased transition probability out of 'regular employment', with the exception of the younger workers for whom the decrease in the rate of entry into 'regular employment' has also been an important reason of such a decline.

고상반응법(solid-state reaction)으로 산화물 초전도체 Bi$_{2+x}$ Sr$_{1.8}$ $CaCu_2$$O_{8+\delta}$(-0.2$\leq$x$\leq$0.2)을 제조하여 조성변화에 따른 산소량과 Bi 이온의 하전가(valence)가 구조변조의 주기에 미치는 영향을 조사하였다. 2212상의 단일상 고용한계는 -0.1$\leq$x$\leq$0.1 영역이었다. 이 영역에서 x의 증가에 따라 격자상수 c는 감소를 보이며, 온셋 임계온도 Tc$^{on}$ 과 산소량은 증가하는 경향을 보였다. 또한, Bi 이온의 하전기와 구조변조의 주기는 단일상 고용한계 영역 내에서 x의 증가에 따라 감소하는 경향을 보이고 있다. 구조변조의 주기는 산소량이 증가함에 따라 감소하고 Bi 이온의 하전가 증가에 따라 증가함을 보였다. 즉, 산소의 절대량과 Bi 이온의 하전가에 따라 구조변조의 주기가 변화하는 것을 알 수 있었다.

고분해능 전자현미경과 컴퓨터 이미지 시뮬레이션이 La이 첨가되고 또한 첨가되지 않은 Pb(Mg/ sub 1/3/Nb$_{2}$3/)O$_{3}$고용체의 미세구조를 연구하기 위해서 사용되었다. 불규칙격자 영역의 격자 이미지는 정방정 형태와 유사 육방정 형태를 각각 보였다. 규칙격자 영역에서 Mg과 Nb의 비화학양론적인 규칙격자 구조 현상이 <111>방향에 따라 관찰되었다. 실험 격자 이미지와 컴퓨터 시뮬레이션 이미지의 비교로부터, 규칙격자 구조를 가지는 영역의 장거리 규칙도는 0.2-0.7의 값을 가지고 있었고, 또한 규칙격자는 (NH$_{4}$)$_{3}$FeF$_{6}$결정구조를 가지고 있었다. 작은 값의 장거리 규칙도를 가지는 규칙격자를 가지는 영역에서, 변형률 파형이 관찰되지 않았다. 이것은 대부분 두 양이온이 그들의 위치에 있기 때문에, 원자 변위가 없었기 때문이다.

In this research, we explore the effects of changes in industrial structure due to industrial restructuring on employment and growth in the Korean economy. To that end, we first investigate the impact of industrial restructuring on employment through Lilien's sectoral shift hypothesis, considering the dependence of industrial restructuring on business cycles. As a result of the analysis, we find that changes in the industrial structure have exerted a short-term effect of increasing unemployment, and that the effects of industrial restructuring are even greater during the economic downturn period. In light of these points, Lilien's sectoral shift hypothesis seems to be valid in Korea. Next, we examine the effect of industrial restructuring on economic growth in Korea by analyzing which one, between the Kuznetz hypothesis and the Baumol effect, is dominant. Empirical results reveal that the mid- to long-term effect of industrial restructuring on GDP growth is significant, which is in accordance with the Kuznets hypothesis, where resource allocation along with industrial restructuring to sectors with high productivity spurs economic growth.
