Agricultural extension services in Korea has experienced various system changes and accomplishments. The biggest achievement of extension was rice self-suffiency in the 1970s and abundant vegetable and animal production in the 1980s. The emerging challenges of international competition and localization are contributing to significant changes such as the decentralization of activities and shared responsibilities between the central government and local governments. Change, while it threatens the status quo, is a challenge and an opportunity to review and revamp ensconced and often rigid structures. In this sense, it is time to start a new era in agricultural extension. The development of agricultural extension requires keen appraisals and cogent analysis based on the realities of each specific regional situation. In order to develop agricultural extension services, the various aspects, the synthetic identification of its environments, the clarification of the client, the program development, and the effective mechanisms between research and extension must be considered. Especially, agricultural extension systems should be flexible and adjust to changing environments and the farmers' needs.

Korea has exerted her efforts to assimilate nuclear power technology, and reportedly localized 95 percent of nuclear power technology by 1995. This paper investigates the evolution of nuclear power program in Korea to exploit the development process of the nuclear power industry and key factors for the technological localization of nuclear power plant. In developing countries, an imitative catching-up process can be shown as a course for developing the absorptive capacity of foreign technology, which depends on prior knowledge base and the intensity of effort. The process of technological learning consists of five stages including preparation, implementation of foreign technology, acquisition of peripheral technology, acquisition of core technology, and improvement f foreign technology. Moreover, this paper discusses six essential factors that have influenced the successful achievement of technological localization of nuclear power plants in Korea. They include the role and strategies of the government, the leading role of utility firm, the development and cooperation of the related organizations, the development of human resources and their efforts, market conditions and the assistance of foreign donors, and social conditions. Finally, this paper discusses about implications offered by the Korean experience for other developing countries.

Environmental conditions during early mammalian embryo development are critical and some adaptational phenomena are observed. However, the mechanisms underlying them remain largely masked. Previously, we reported that AQP5 expression is modified by the environmental condition without losing the developmental potency. In this study, AQP11 was examined instead. To compare expression pattern between in vivo and in vitro, we conducted quantitative RT-PCR and analyzed localization of the AQP11 by whole mount immunofluorescence. When the fertilized embryos were developed in the maternal tracts, the level of Aqp11 transcripts was decreased dramatically until 2-cell stage. Its level increased after 2-cell stage and peaked at 4-cell stage, but decreased again dramatically until morula stage. Its transcript level increased again at blastocyst stage. In contrast, the levels of Aqp11 transcript in embryos cultured in vitro were as follows. The patterns of expression were similar but the overall levels were low compared with those of embryos grown in the maternal tracts. AQP11 proteins were localized in submembrane cytoplasm of embryos collected from maternal reproductive tracts. The immune-reactive signals were detected in both trophectoderm and inner cell mass. However, its localization was altered in in vitro culture condition. It was localized mainly in the plasma membrane of the blastocysts contacting with external environment. The present study suggests that early stage embryo can develop successfully by themselves adapting to their environmental condition through modulation of the expression level and localization of specific genes like AQP11.

본 연구는 중국의 광고산업의 지역화와 상대적 효율성을 분석하고 있다. 중국의 광고산업은 급속하게 성장하는 산업 중의 하나이다. 특히 지역경제발전수준이 높아지고 소비행태가 고급화되고 다양화될수록 지역광고시장의 규모는 더욱 발전할 것으로 예상된다. 본 연구는 이러한 지역적인 특성을 실증분석하기 위해 입지지수를 이용하여 지역특화정도를 비교하고 있다. 그리고 DEA-Window 분석 방법을 이용하여 광고산업의 지역별 상대적 효율성을 분석 비교하고 있다. 분석결과에 의하면, 첫째 광고산업의 상대적 효율성이 높은 지역일수록 지역특화 정도도 높게 나타난다. 이는 산업의 집중과 산업의 효율성 간에 관계가 있음을 나타낸다. 둘째 중국의 광고산업이 지역별로 다극화되고 있다는 점을 들 수 있다. 북경시를 중심으로 하는 거대한 발전축이 형성되고 있으며 상해시, 강소성, 절강성을 중심으로 하는 또 하나의 발전축이 형성되고 광동성을 중심으로 하는 발전축이 형성되고 있다. 셋째 중부지역과 서부지역의 광고산업이 비록 상대적 효율성은 크게 높지는 않지만 지역특화 정도는 높게 나타나는 지역들이 있다는 점은 향후 발전 잠재력을 나타내고 있다.

Recently, with increasing the number of patients with head injury and cerebrovascular accident, there has been an increasing need for the useful assessment tools of brain dysfunction and it's localization. With the advances in the neuroscience since the mid-1970s, particularly in the areas of neuroanatomical tracing, neuroimaging, and improved behavioraltest design, it has been possible to develop a more precise understanding and localization of brain dysfunction. However, these equipments are not readily available in the private clinics and too expensive to use as a screening tool to all suspected patients with brain dysfunction. Although several screening tests such as Mini-Mental States Examination(MMSE) or Brief Cognitive Rating Scale(BCRS) are simple in use and useful for the brief assessment of brain dysfunction, these are also limited in using for localization of brain dysfunction because of their simplicity. With increasing need of the assessment tool which is able to localize the dysfunction more precisely in the clinical practice, we planned to develop the new assessment tool, the Bedside Neurocognitive Function Localization Test(BNLT) which is suitable for this purpose. The BNLT was designed to be utilized for localizing brain dysfunction effectively and readily in the clinical practice. We introduced the whole process of designing the BNLT in this manuscript.

In the 21st century modem architecture, not only environmental problems and sustainable development but also two subjects, 'Globalization' and 'Localization', have become important issues. The modern application of vernacular design which is the design model including the characteristics of region, a people and tradition can be a solution for localization and sustainable development. Vernacular design gives many ideas in respect of organic art and design, the dilemma of modern architecture, and practical solution of its problems, and is considered as an important resource of modern ecological architecture. This study aims to investigate the meaning and types of vernacular design and confirm the development possibility of this design as the important element of modem regional ecological architecture. In addition, through case studies, it will demonstrate that the regional ecological architecture based on vernacular design can solve new multidimensional architectural problems in the 21st century.

This paper introduces the development of a range sensor based integrated navigation system for a multi-functional indoor service robot, called PSR (Public Service Robot System). The proposed navigation system includes hardware integration for sensors and actuators, the development of crucial navigation algorithms like mapping, localization, and path planning, and planning scheme such as error/fault handling. Major advantages of the proposed system are as follows: 1) A range sensor based generalized navigation system. 2) No need for the modification of environments. 3) Intelligent navigation-related components. 4) Framework supporting the selection of multiple behaviors and error/fault handling schemes. Experimental results are presented in order to show the feasibility of the proposed navigation system. The result of this research has been successfully applied to our three service robots in a variety of task domains including a delivery, a patrol, a guide, and a floor cleaning task.

Nek2 is a mammalian protein kinase that is structurally homologous to NIMA, a mitotic regulator in Aspergillus nidulans. To understand cellular processes in which Nek2 participates during mammalian development, we investigated the expression and subcellular localization of Nek2 in vivo. The Nek2 protein was detected in spermatocytes and in a fraction of actively dividing ovarian follicle cells and of embryonic tissues. We also observed that Nek2 was localized in both the nucleus and centrosome in embryonic cells. Such localization pattern supports the proposal that Nek2 is a mitotic regulator that is involved in multiple cell cycle events during mammalian development.
