This paper tries to analyze technologies of search engine generally, and reveal the additional modes of Korean search engine at the same time. Recently it said that search engine becomes a self-moving and is getting more strong power than the former one existed. There are many difference interpretative views from technological determination to instrumentalism surrounding this system. Search engine invents the technological mode that draws user's attention to make its own expertise reinforce. It is stemmed from the rationality of its own. Especially Korean search engine exposed unique mutation as self-proliferation of it during past a decade, as for example "related keyword" or "real-time popular keyword" service. Its automatic decision aroused democracy matter, now it is not only web guide. How we do make it to serve in democracy, accepting the independent expertise of it simultaneously? We might find new prospect when focusing on interactional modality between engine and human actor, instead counting both as a separate one.

Nuclear power has been an attractive energy efficient and to the pressure with the climate change despite of its risks. There are safety, security, and environmental concerns with the nuclear radiation, but the techno-optimism forms the mainstream by experts and the state to be able to control and manage the risks yet occurred. The disastrous Chernobyl and Fukushima nuclear accidents brought about alternative action and thought including renewable energy expansion, efficient energy delivery and use, and enhancing stewardship to environmental carrying capacity. More significant alternative movement is sought by victims of nuclear radiation, technicians, and the general public who realized the pitfalls of expert and state centered policy formation. These laypersons become counter-expertise competent in recognizing local contamination and considering the risks and emotions seriously affecting peoples' everyday lives. They play important roles in the construction and legitimation of alternative knowledge about nuclear power widely realized across regions.

자기 주도적 문제해결 학습모형은 구성 주의적 학습원칙에 의거한 교수-학습모형으로서 학습자의 학습과정에 대한 적극적 참여(구체적 학습목표 설정, 학습내용과 방향 결정 및 평가에 참여)를 강조한다. 또한 자기 주도적 문제해결이라는 용어에서 알 수 있듯이, 기존의 교과서 중심의 강의전달식과 달리, 학습자의 실제 생활과 밀접하게 관련된 복잡하고 비구조적 '문제'와 PBL에서 제시하는 '문제해결도구'를 사용하여 학습을 진행한다. 결과적으로 본 PBL수업사례는 위의 질문에 대한 매우 긍정적인 결과를 제시함으로서, 요즘 학습자 주도적 학습모형으로 제기되는 여러 모형들과 더불어 기존 학습에 대한 하나의 대안적 접근으로서의 가능성을 보여주고 있다.

자본주의의 태동 이후 산업혁명과 정보혁명 등 기업은 끊임없이 새로운 혁명적 환경에 노출되고 있으며 이에 따라 기업가 정신 또한 시대에 따라 재정의 되어 왔다. 기업가 정신은 창업 기업 뿐 아니라 기존 기업에 있어서도 기업 경영의 커다란 원동력으로 자리 잡고 있다. 씨써클은 문화의 새로운 명칭으로, 구성요소에는 오픈 마인드와 스피릿이 있으며 창의성과 포용성, 영성을 내포하고 있다. 본 논문에서는 기업가 정신을 씨써클 관점에서 파악하여 이를 기업에 적용할 수 있는 틀을 제시하고자 한다.

This paper focuses on recontextualizing geography curriculum, i.e. examining recent changing aspects in three geography curriculum locators-society, student and discipline of geography-and searching future directions of geography curriculum in light of such changes. For conciliation and reflection of changing aspects of each locators, this paper dealt with social issues and societal changes in terms of locator of society, increased concern to student and development of cognitive science in terms of students, and challenging views on science and the meaning of epistemological changes in geography in terms of discipline. As a result, three future directions in geography curriculum are searched : issue-based geography curriculum, thinking geography curriculum, geography curriculum toward equity and accessbility.

Recently it is supposed to be a shift to regional geography. To understand the emergence of the new regional geography, It must be remarked that the progress of capitalist production and consumption change our conceptional apparatus such as representation of space. Region is one of the important mode of representations of space and time. In the Fordist capitalism of 20th century, development is regarded as diffusion of capitalist expansion of western worlds. State must support capitalist growth through regional policies which include constructing of infrastructure and regionalization of spatial division of labour. The regional development theories contributed as ideology and policy tools for state intervention. The region was simply one of the most logical classification tools of organizing geographical informations. In the theories of regional development, the concept of region was reduced to the formal unit of classification. As the transition from Fordism to flexible accumulation, the region is again acquiring its 'identity' and 'authenticity'. In this tendency of the revival of region, it is expected that good achievement could be made in the field of regional geography through relevant research methods. It is also believed one of the available means are historical approaches to the cultural and ecological regions. The historical approaches to cultural and ecological regions are not only correspondent with cultural development strategies of local governments, but also could convey regional identities through both narrativization of place and aestheticization of landscape.

Mid of 1980s witnessed the beginning of a new trend regarding the elderly as the Third Age Group, which is capable of positive selection for their later life. These changes are caused not only by the rising cost of caring them as the dependent to the society, but also by paradigm shift from the clinical and biomedical model to political economy and critical gerontology. The paradigm shift is based on the social constructionism as a perspective on the later life. In this communication the development of social constructionism is reviewed as an approach on the living environment for later life through literature survey. Emphases were made on the anti-ageism instead of ageism in the analysis of the social constructionism perspective for living environment in later life. Individual practice, influencing the practice of others, influencing agency policy, and developing theory were addressed and emphasized for the practice of anti-ageism. This study found the importance of the development of the social constructionism perspective on the study and practice regarding living environment for ‘the Third Age’ in Korean situation.

대형 상용차용 내연기관에서 방출되는 소음의 음압 레벨은 경우에 따라 140dBA 이상으로 환경소음 배출규제에 부합되는 배출 소음을 위하여는 소음기의 적절한 설계가 필요하다 하겠다. 소음기는 방출 소음을 저감시키는 기본적인 작용 이외에 엔진의 효율을 저하시키는 배압(back-pressure) 상승의 효과를 동반할 뿐만 아니라 차체에의 장착을 위하여 크기와 무게의 제약을 받는다. 따라서 소음기는 설계자의 경험과 과거에 사용되어 온 소음기에 대한 이해, 소음기를 구성하는 단위 요소에 대한 음향학적 해석이론, 제작 과정에서의 경험과 튜닝 등에 바탕을 두고 설계되어져 왔다. 본 연구에서는 대형 상용차에 장착되는 기존 소음기 구성요소의 투과 손실(Transmission Loss: TL)을 전달 행렬법으로 해석하여 음향학적 특성을 규명하고 개별 소음기 요소에 대한 기존의 연구 결과를 바탕으로 공명기와 다공 요소를 이용하여 기존 소음기를 재설계함으로써 배출 소음의 저감을 이루어 나간 과정을 소개하고 이를 적용 사례를 중심으로 살펴보고 있다. 소음기의 설계를 위하여 고려할 수 있는 음향학적 요소는 그 기능과 형태면에서 다양하나 본 연구에서는 대형 상용차용 소음기에 주로 사용 가능한 공명기와 다공관을 주된 설계요소로 생각하였다. 공명기는 공명 주파수 대역의 소음을 저감하는 역할을 하므로 일정한 엔진 회전수 하에서 엔진의 방출 소음중 폭발 성분에 의한 소음을 줄이는데 효과적으로 사용될 수 있지만 가속 주행시에는 회전수(rpm)의 변화에 따라 폭발 주기가 변화하게 되므로 공명기의 설계에 주의를 기울여야 한다. 내연 기관용 소음기에 빈번하게 쓰이는 다공 요소의 해석 방법으로는 Sullivan[1], Kim and Yoon[2] 등의 분할 접근 방법(Segmentation approach)과 Jayaraman and Yam[3], Munjal[4], Peat[5] 등의 연성 제거 방법(Decoupling Approach)등이 제시되었고 평면파 영역에 한하여 해서되어져 왔다. 본 논문에서는 분할 접근 방법(Segmentation Approach)을 이용하여 다공 요소로 이루어진 소음기를 해석하는데 적용하였다.

Constructivism gave many implications to science education but at the same time it has brought confusion about its implication to the field of science education. Hermeneutics has possibilities of being able to reduce confusion as well as opening a new horizon. Hermeneutics seeks the meaning of 'real understanding' through the concepts of horizon, hermeneutical circle, and fusion of horizons. Both hermeneutics and constructivism have positive attitude to students' pre-understanding and accept contextualization of knowledge. Thus, they both can criticize traditional teaching method and propose an alternative. Moreover, hermeneutics approaches human understanding holistically with the concept of horizon, and pays attention to the circularity of the process of human understanding. As a result, hermeneutics can open a new horizon and give new discourse to science education and contribute to the development of research and practice of science education.
