이 연구의 목적은 서구적 시각에서 제시하는 동아시아 복지국가 담론에 대한 비판적 검토와 한국 복지국가의 구조적, 유형적 특성을 그러한 비판과 비교하여 제시하는 데 있다. 동아시아 복지모델을 대표한다고 볼 수 있는 유교주의 복지국가 개념을 가지고는 오늘날의 역동적이고 독특한 동아시아 사회의 성격과 특징을 담아내기 어렵다. 동아시아 국가로서 한국 복지국가(레짐)는 서구 와 북구 복지국가들에 비해 기원, 형성배경, 정책노선 그리고 정책행위자의 차원에서 아주 분명한 차이를 보이고 있다. 따라서 동아시아 복지모델 연구의 새로운 접근 방법이 요구된다. 한국 복지국가(레짐)의 기원과 발전은 권위주의적 발전국가개념과 이론적 준거 틀의 범위 안에서 이해와 설명이 가능하다. 역사적으로 1980년대의 한국 사회의 민주화와 1990년대 말의 금융위기는 한국의 복지정책과 제도 발전에 기여하였다. 일본, 대만, 홍콩, 싱가포르 등 동아시아 국가들의 복지정책과 제도들은 많은 유사점들을 지니고 있다. 이 국가들 간의 비교연구는 동아시아 복지국가에 대한 새로운 이론 발전에 의미 깊고 유효한 결과들을 가져다주게 될 것이다. 개별 국가들에 대한 사례연구와 복지국가 연구자들 간의 국가 간 상호교류의 활성화는 새 동아시아 복지모델 개발에 매우 중요시된다.

In this research, authors tried to measure the shape of the nozzle throat of KL-3 engines, which is the main engine of KSR-III rocket, to find the increase of nozzle area caused by the thermal ablation. For the purpose, we invented an image-based method instead of the 3D pointer, which is actually inaccessible to such large scale engines. As a result, our equipment showed satisfactory accuracy and performance. Analysing the results of experiments, we find that the pattern of ablation is determined by the spray pattern and that the process of thermal ablation phenomena can be categorized in three regimes - the first regime that the shape of nozzle throat is maintained and ablation is negligible, the second regime that saw-tooth form is developed and ablation is accelerated, and the third regime that the saw-tooth form is already established and the growth of ablation rate is reduced. Also, we find that the ratio of area increase after 60 seconds combustion is +5.82% and conclude that this figure is acceptable and satisfactory.

Salinity ecotypes in Ulva pertusa Kjellman were examined for the growth responses of the three isolates taken from different salinity regimes. All isolates showed a broad salinity tolerance, but growth patterns were correlated with the salinity regime of their original habitat. The germlings from Anin exhibited optimum growth at the native salinity of 32%. The germlings from Yongyon which had hypersaline habitats were tolerable to high salinity, i.e. growth rates peaked at 40%, whereas those from Samgando which had low salinities achieved maximum growth rate at 24\%. The germlings of inter-isolate cross demonstrated intermediate growth response between that of their respective parents. Our data also clearly indicated intraspecific differences among the three isolates, which was interpreted as development of different physiological ecotypes. We conclude that U. pertusa may consist of several ecotypes, each of which has some capacity for physiological adaptation to salinity variations.

The flow regimes for a Taylor-Couette flow with a stable, axial stratification in density are investigated using numerical simulation. The flow configuration identical to that in the experiment of Boubnov, et al. (1995) is considered in the present research. The main objectives of this investigation are to verify the experimental and numerical results carried out by Boubnov, et al. and Hua et al. (1997), respectively, and to further study the detailed flow fields and flow bifurcations. With increasing buoyancy frequency of the fluid (N), the stratification-dominated flow regime, called the S-regime, is observed. It is also confirmed that the important effect of an axial density stratification is to stabilize the flow field. The present numerical results are in good agreement with Boubnov, et al. and Hua et al.'s observations.

Our goal is to relax a sufficient condition for the exponential almost sure stability of a certain class of stochastic differential equations. Compared to the existing theory, we prove the almost sure stability, replacing Lipschitz continuity and linear growth conditions by the existence of a strong solution of the underlying stochastic differential equation. This result is extendable for the regime-switching system. An explicit example is provided for the illustration purpose.

USA has distinct differences of economic policy by a ruling party. And, USA economy has mainly influenced on it of Korea. So, we examine whether a ruling party of Korea has different regime including rate of return in stock market. The Republican Party and Democratic Party have based on Milton Friedman and Keynes economy at each other's economic policy in the USA The Republican Party and Democratic Party have different interest level and excess return on equity, GDP growth rate, unemployment rate. Also, a ruling party of Korea has different regime and economic activity in this paper.

Linear stability analysis of radiating counterflow diffusion flames is numerically conducted to examine the instability characteristics of cellular patterns. Lewis number is assumed to be 0.5 to consider diffusional-thermal instability. Near kinetic limit extinction regime, growth rates of disturbances always have real eigen-values and neutral stability condition of planar disturbances perfectly falls into quasi-steady extinction. Cellular instability of disturbance with transverse direction occurs just before steady extinction. However, near radiative limit extinction regime, the eigenvalues are complex and pulsating instability of planar disturbances appears prior to steady extinction. Cellular instability occurs before the onset of planar pulsating instability, which means the extension of flammability.

이 연구의 목적은 메타경로분석의 방법론을 적용해 최근 부모수당제도의 도입을 중심으로 독일의 일-가정 양립정책과 젠더레짐의 변화의 실제와 동학을 규명하는 것이다. 일-가정 양립정책에서 '계층화'가 이루어지고 있는데, 정치적 장벽이 해소돼 부모수당제도를 도입할 수 있었던 반면 기존 가족주의 지지세력의 제도 내부적 장벽으로 인해 아동양육수당제도를 고수하지 않을 수 없었다. 그러나 부모수당제도는 '차별적인 성장'으로 활성화돼 독일 젠더레짐의 지배적인 구조를 '순차적 양립'에서 '동시적 양립'으로 변화시키는 핵심적인 보완성의 변화를 낳고 있다. 한편 주요 정치적 행위자들은 젠더영역에 대한 '의도적 분리'를 통해 전체 독일모델의 핵심적인 제도영역 간의 조정관계의 이완 가능성을 차단하려 하고 있다.

Objective: To evaluate the use of nurse sows and post-weaning nutrition strategies for low wean weight (WW) pigs on lifetime growth and efficiency. Methods: Animals (n = 270) were assigned to one of five treatments at 28 d. Low WW pigs (<6 kg) were either weaned and offered a special dietary regime recommended for low WW pigs (WEAN) or placed on a nurse sow (NURSE) and weaned at 49 d. Normal WW pigs (9 kg) (NORM) were also weaned at 28 d. After weaning, NORM and NURSE pigs were offered either a 'high' (4 kg/pig of starter 1 diet followed by 8 kg/pig of starter 2 diet) or 'low' (8 kg/pig of starter 2 diet) starter diet allowance in a 2×2 factorial arrangement. A typical grower diet was then offered, followed by a typical finisher diet until 147 d of age. Results: NORM pigs where heavier throughout their life compared to NURSE pigs (91.4 kg vs 76.2 kg at 147 d; p<0.001). WEAN pigs were heavier at 70 d compared to NURSE pigs (23.9 kg vs 21.0 kg; p<0.001), but there was no significant difference at 147 d between NURSE and WEAN treatments. NURSE pigs had reduced feed intake throughout the finishing period (1.6 kg/d; p<0.001) compared to WEAN (2.0 kg/d) and NORM (1.9 kg/d) pigs. Feed conversion ratio (FCR) of NURSE (2.20) was lower than NORM and WEAN during the finishing period (2.40 and 2.79, respectively). Conclusion: Extended (up to 49 d) nursing for low WW pigs resulted in improved FCR during the finishing period, but no overall improvement in growth rate compared to low WW pigs weaned at 28 d and offered a specialised starter regime. Normal WW pigs where significantly heavier than low WW pigs throughout the study.

The mesh-insensitive structural stress procedure by Dong is modified to apply to the welded joints with local thickness variation and inignorable shear/normal stresses along local discontinuity surface. In order to make use of the structural stress based K solution for fatigue correlation of welded joints, a proper crack growth model needs to be developed. There exist some significant discrepancies in inferring the slope or crack growth exponent in the conventional Paris law regime. Two-stage crack growth model was not considered since its applications are focused upon the fatigue behavior in welded joints in which the load ratio effects are considered negligible. In this paper, a two-stage crack growth law considering high mean loading is proposed and proven to be effective in unifying the so-called anomalous short crack growth data.
