This article attempts to trace and critically review the development of immigration policies in Korea since the early 1990s. International migration as a global and universal phenomenon has challenged nation states, and theories of immigration policy seek to identify and explain factors affecting the choices made by states in this regard. However, two dominant theories, the political-economy and neo-institutionalist approaches, both of which emphasize economic interests and liberal principles, respectively, fail to provide a satisfactory explanation of the complex process of immigration policymaking when it comes to other factors including security and ethno-cultural diversity. Therefore, this article adopts the theory of the functional imperatives of the state, as suggested by Christina Boswell, focusing on security, accumulation, fairness, and institutional legitimacy in order to examine the complexity of immigration policymaking. Adopting Boswell’s theoretical framework, this article explores what functions of the state-embedded immigration policies have been emphasized by each administration since the early 1990s. This article also seeks to examine whether there have been changes in the immigration policy under the current Lee Myung-bak administration and, if so, in what areas the current government’s policy is distinguished from the policies of the two previous administrations.
특집논문 : 한국 이민관련 정책의 입법과정에 관한 연구
이병하 한국의회발전연구회 2011 의정연구 Vol.17 No.1
본 연구의 목적은 한국 이민관련 정책들을 윌슨의 정책유형에 따라 분류하고 정책유형에 따라 다른 입법과정을 거치는지를 분석하는데 있다. 본 연구는 기존 이민정책 연구에 있어서 간과되었던 국회 입법과정에 초점을 맞춤으로써 그간의 연구들이 주목하였던 시민사회단체의 영향력, 행정부처 간 관계, 사법부의 역할 등을 보완할 수 있다는 점에서 연구 의의를 찾을 수 있겠다. 이민정책이 크게 이민통제와 이민자 통합이라는 두 축으로 나뉜다고 할 때 이민통제 부분에서 ``외국인근로자의 고용 등에 관한 법률,`` 이민자 통합 부분에서 ``재한외국인처우기본법,`` 그리고 ``다문화가족지원법``을 연구대상으로 하여 입법과정을 분석하였다. 연구결과, 이민관련 정책이라고 하더라도 정책유형 상 다른 유형으로 분류된다면 서로 다른 입법과정을 거치게 된다는 것을 확인하였다. 이민통제 부분에서는 윌슨의 정책분류 상 이익집단정치의 특징을 나타내 특정 집단 간에 첨예한 대립양상이 있었던 반면, 이민자 통합 부분에서는 고객정치의 특징을 보이며 특별한 반대 없이 신속한 입법과정을 거쳤음을 알 수 있었다.

The outcome of primary surgery for cleft lip is judged by its effects on the quality of oro-facial function and development. Many surgical techniques have been tried to obtain better results, however, Delaire introduced a technique of functional closure of the lip and nose, based on the findings of no true hypoplasia in the tissues either side of the cleft. In a seven-month-old Asian male patient with unilateral incomplete cleft lip, we carried out the primary closure by modified Delaire's technique. With no alveolar bone graft, the vertical incision on the nasal base was omitted in this patient because of his acceptable symmetry of nose. Also, a small Z plasty was added on the non-cleft side. The V-shaped incisions, whose notch was located on each side of the red vermilion, were designed and beveled incisions were performed for the rehabilitation of lip length and thickness, considering the postoperative wound contracture. We assured that this modification of Delaire's technique could be applied for various cases of primary closure of incomplete cleft lip.
$\alpha$-Sialon/SiC Whisker 복합재료의 기계적 물성 및 마모 특성 연구
이병하,김인섭,이경희 한국세라믹학회 1993 한국세라믹학회지 Vol.30 No.10
Sialon ceramics are presently seen as promising materials with high hardness, strength, fracture toughness and corrosion resistance for friction and wear applications. The objective of present work is to improve of mechanical properties and wear resistance of $\alpha$-Sialon(x=0.4) by addition of SiC whisker. $\alpha$-sialon(x=0.4)/SiC whisker composites were obtained by hot-isostatic pressing at 173$0^{\circ}C$ for 1 hour under 1757Kg/$\textrm{cm}^2$ N2 pressure after pressureless sintering the mixture of Si3N4, Y2O3, AlN at 1780~180$0^{\circ}C$ for 3~5 hours in N2 atmosphere. As the amount of SiC whisker content increased, relative density and hardness were decreased, however fracture toughness, bending strength and tribological properties were improved. Tribological properties of $\alpha$-Sialon/15 vol% SiC whisker composite were improved in spite of its low mechanical properties.

In this paper, the charging characteristics of series resonant type high voltage capacitor chargers considering the transformer stray capacitance have been studied. The principles of operation for the four operational modes and the mode changes for the four different switching frequency sections are explained and analyzed in the range of switching frequency below the resonant frequency. It is confirmed that the average charging currents derived from the above analysis results have non-linear characteristics in each of the four modes. The resonant current, resonant voltage, charging current, and charging time of this capacitor charger as variations of the switching frequency, series parallel capacitance ratio (k=Cp/Cs), and output voltage are calculated. From the calculation results, the advantages and disadvantages arising from the parallel connection of this stray capacitance are described. Some methods to minimize charging time of this capacitor charger are suggested. In addition, the results of a comparative test using two transformers whose stray capacitances are different are described. A 1.8 kJ/s prototype capacitor charger is assembled with a TI28335 DSP controller and a 40 kJ, 7 kV capacitor. The analysis results are verified by the experiment.
