Generally, regime shift occurs less frequently than policy change and/or government change. Regime shift needs alterations and changes along the three critical components which constitute a domestic regime: (1) the character of the socioeconomic coalition that rules the country; (2) the political and economic institutions through which power is acquired and exercised; and (3) the public policy profile that give political direction to the nation. This paper tries to examine characteristics of the welfare regime of Korea, and explore policy reform options for the welfare regime shift in Korea. From the viewpoint of livelihood security perspective, I firstly tries to examine development process of Korean welfare regime and specify the main characteristics of that regime. Secondly, I present three policy reform options: (1) reform of the formal political institutions such as electoral system and government type; (2) restructuring of the composition of government expenditure structure; and (3) reduction of the informal employment. These three policy reform options are related to the alteration of socioeconomic coalitions and the changes of the political and economic institutions. Instead of concluding remarks, I finally suggest two debate topics to the round table discussion.

BIDANI is the action-research program. BIDANI aims to be truly a people's program embodying their own activities and aspiration. BIDANI sees an integrated development approach at the community level with participatory services embodied in a Barangay Integrated Development Plan(BIDP) designed by the people themselves. Community situational analysis is conducted by the people to identify the priority problems and potential resources in the barangay. Participatory planning, using the “bottom up” apporach, is exercised to formulate a BIDP. Proper motivation and advocacy encourage barangay people's participation. Accessibility and efficiency in the use of various services and resources of government and private agencies increase. Family groups who are at high-risk to malnutrition become aware of the importance of nutrition through their participation in development program activities. Integration of political and socio-economic concerns at the lowest level is operationalized. Implementation and sustainability of the program on a wider scale from a model project to a model program is facilitated through institutionalization at the municipal/city level with the mayor as the project director. “Top to bottom” planning through a City/Municipal Integrated Development Program(C/MIDP) interacts with “bottom up” planning at the barangay level. The establishment of a local Training School for Barangay Development(TSBD) in each municipality and city for continuing education of indigenous village workers and barangay people is a vital component for success and viability. The role of non-political entities such as academic institutions and non-government organizations, as catalytic agents of development, is stressed.

Nutritional assessment of transgenic crops to improve safety evaluations is important for food production. An oxidative stress-tolerant rice was generated by stable insertion of the TC gene-a tocopherol cyclase isolated from tobacco-into the genome of a common variety of japonica colored rice. The nutritional composition of the brown rice grains from the transgenic TC line was compared with that of the parental rice cultivar Heugnambyeo and two different varieties of non-transgenic rice. The results indicate that the analyzed nutritional compositions of the brown grains from the transgenic TC line were within the range of values reported for other commercial lines, and measurements of nutritional compositions were equivalent to those of the non-transgenic rice.

The rates of infiltration contributed to the flow fo water in an unconfined aquifer under the partially penetrated stream at an ungaged station and the corresponding base flow in channel are coupled by using the hydraulic and/or hydrologic characteristics obtained from the geomorphologic and soil maps. For the determination of groundwater flow, the linearized model which is originally Boussinesq's nonlinear equation is applied in this study. Also, a stream flow routing model for base flow in channel is based on a simplification of the Saint-venant. The distributed runoff model with piecewise spatial uniformity is presented for obtaining its solution based on a finite difference technique of the kinematic wave equations. The method developed in this study was tested to the Bocheong watershed(area : $475.5km^2$) of the natural stream basin which is one of tributaries in Geum River basin in Korea. As a result, it is suggested that the rationality of hydro-graph separation according to a wide variability in hydrogeologic properties be worked out as developing the physically based subsurface model. The results of the present model are shown to be possible to simulate a base flow due to an arbitrary rate of infiltration for ungaged basins.

마찰교반접합(Friction Stir Welding)은 1991년 영국 TWI에서 개발된 접합 법으로서 일정한 속도로 회전하는 툴이 재료내부에 삽입 되면서 툴과 재료사이에서 마찰열이 발생하여 연화된 재료와 접합 툴 사이에서의 기계적 교반에 의해 소성변형이 일어남과 동시에 접합이 이루어진다. 마찰교반접합은 동적 재결정에 의한 접합부의 미세한 결정립 형성으로 인하여 기계적 특성이 향상되며 보호 가스가 필요 없어 친환경적임과 동시에 용융 용접 법에 비해 접합 시 에너지 소모가 적다는 장점이 있다. 마찰교반접합은 기존의 저융점 재료에 관한 접합을 넘어서 최근에는 철계 합금, 타이타늄 합금, 니켈계 합금 등 고융점 재료에서의 적용에 관한 연구가 이루어지고 있다. 하지만 마찰교반접합을 이용하여 위와 같은 강한 재료를 접합하기 위해서는 내구성이 갖추어진 툴이 반드시 수반된다. 슈퍼 오스테나이트계 스테인리스강은 염화물의 농도가 높은 부식 환경에 적용되는 소재로서, 공식(pitting corrosion) 및 틈부식 (crevice corrosion)에 대한 내식성을 높이기 위하여 Mo의 함량을 6%로 낮추고 20~25% Cr과 Ni을 첨가하여 사용된다. 이러한 고합금의 슈퍼 오스테나이트계 스테인리스강은 여타 내식성 합금에 비하여 내식성이 매우 우수한 것으로 알려져 있다. 최근 SO2 배출에 대하여 규제가 강화되면서 화력 발전소용 탈황 설비 중 일부 장비에서 6% Mo가 첨가된 슈퍼 오스테나이트계 스테인리스강의 사용이 늘어나고 있다. 본 연구에서는 $Si_3N_4$ 툴을 사용하여 Mo이 6% 첨가된 슈퍼 오스테나이트계 스테인리스강인 1925hMo강을 마찰교반접합하였다. 툴 회전속도 (200rpm, 300rpm, 460rpm, 700rpm)를 변수로 하여 접합을 실시하였다. 접합 후 외관상태를 점검하였으며 광학현미경 (optical microscope)과 주사전자현미경 (scanning electron microscope)을 사용하여 미세조직 관찰을 하였으며 경도 및 인장강도 측정 등의 실험을 통하여 접합부의 기계적 특성을 평가하였다. 그 후 이러한 결과를 통하여 미세조직과 기계적 특성과의 관련성을 조사하였다.

The purpose of this study is to provide base line data to the educational settings so that more improved occupational core competencies could be taught under the formal curriculum of the technical highschool than before through the inquiry into 'the need for the consolidation of education that principals of technical highschool perceive'. Initial occupational key competencies had been prepared through the literature review on the occupational core competencies and the review on the key competencies by the experts in the field of technical industry had been performed to achieve the purpose of this study. The survey instrument consisting of final 9 occupational key competencies had been developed with the careful consideration for the calculation of the need for the consolidation of education using the Borich's model. The results show that principals for the technical highschool perceive the strong need for the educational consolidation regarding the all 9 occupational core competencies in the whole. However, for the specific key competency of understanding the organization and the mathematical competency, the principals of the technical meister highschool perceive somewhat differently from the principals of the specialized technical highschool. The principals in the meister highschool perceive not much need for the consolidation of education regarding the competency of understanding the organization and the mathematical competency.

This article focused on the meaning of the 1979 Moon Treaty and its future. Although the Moon Treaty is one of the major 5 space related treaties, it was accepted by only 11 member states which are non-space powers, thus having the least enfluences on the field of space law. And this article analysed the relationship between the 1979 Moon Treay and 1967 Space Treaty which was the first principle treaty, and searched the meaning of the "Common Heritage of Mankind(hereinafter CHM)" stipulated in the Moon treaty in terms of international law. This article also dealt with the present and future problems arising from the Moon Treaty. As far as the 1967 Space Treaty is concerned the main standpoint is that outer space including the moon and the other celestial bodies is res extra commercium, areas not subject to national appropriation like high seas. It proclaims the principle non-appropriation concerning the celestial bodies in outer space. But the concept of CHM stipulated in the Moon Treaty created an entirely new category of territory in international law. This concept basically conveys the idea that the management, exploitation and distribution of natural resources of the area in question are matters to be decided by the international community and are not to be left to the initiative and discretion of individual states or their nationals. Similar provision is found in the 1982 Law of the Sea Convention that operates the International Sea-bed Authority created by the concept of CHM. According to the Moon Treaty international regime will be established as the exploitation of the natural resources of the celestial bodies other than the Earth is about to become feasible. Before the establishment of an international regime we could imagine moratorium upon the expoitation of the natural resources on the celestial bodies. But the drafting history of the Moon Treaty indicates that no moratorium on the exploitation of natural resources was intended prior to the setting up of the international regime. So each State Party could exploit the natural resources bearing in mind that those resouces are CHM. In this respect it would be better for Korea, now not a party to the Moon Treaty, to be a member state in the near future. According to the Moon Treaty the efforts of those countries which have contributed either directly or indirectly the exploitation of the moon shall be given special consideration. The Moon Treaty, which although is criticised by some space law experts represents a solid basis upon which further space exploration can continue, shows the expression of the common collective wisdom of all member States of the United Nations and responds the needs and possibilities of those that have already their technologies into outer space.

The discovery of the mirror neuron system (MNS) is one of the most important neuroscientific achievements in the 20th century. Some researchers had reported that MNS dysfunction was discovered in autism spectrum disorders (ASD). Finally, the 'broken mirror' theory of ASD was announced in the mid 2000's. According to this theory, ASD cannot simulate the mind and behavior of others due to MNS dysfunction; therefore, they cannot imitate the behaviors and empathized with the mind of others. However, ASD does not always show imitation problems. The researchers who have criticized the 'broken mirror' theory proposed the 'social top-down response modulation (STORM)' theory. On STORM theory, the medial prefrontal cortex or temporo-parietal junction, brain areas related with mentalising, might modulate MNS according to social context. We compared the strengths and weaknesses of each theory.

The purpose of this study is to investigate mathematics content knowledge(MCK) of pre-service teachers about the area of a circle. 53 pre-service teachers were asked to perform four tasks based on the central ideas of measurement for the area of a circle. The results of this study are as follows. First, pre-service teachers had some difficulty in describing the meaning of the area of a circle. Quite a few of them didn't recognize the necessity of counting the number of area units. Secondly, pre-service teachers had insufficient content knowledge about the central ideas of measurement for the area of a circle such as partitioning, unit iteration, rearranging, structuring an array and approximation. Lastly, few pre-service teachers understood the concept of actual infinity. Most students regarded the rectangle as the figure having the approximation error instead of the limitation from rearranging the parts of a circle.
