The new movement in science education in America and Europe has been heavilly oriented into technological and soceital aspect of science since 1970. However, this spirit has not been well informed in Korea and not adapted in science education. This paper aimed to arouse Korean science educators attention to everyday situation as a science education context. In this paper, the discipline centered science education was briefly reviewed and problems related to the philosophy was pointed out. At the same time the researcher introduced STS context as a science education objective, and elaborated the three elements(physical situation, technological situation. and societal situation) of the context. In the paper, the advantages of the use of everyday context in science education were examined. THe advantages were analysed in terms of the nature of science, learning psychology, integrated science, and societal aspect of science education. The paper also suggested the criteria to select teaching materials from STS context. The suggested criteria were the degree of science concepts involvement, frequency of experience, strength of experience, and possibility of direct experience.

본 연구는 창의적이고 통합적인 사고의 활성화를 위하여 과학 문항에 예술적 요소와 기술적 요소를 도입함에 따른 효과를 알아보기 위한 것이다. 평가 문항은 수능에 예술적 요소와 기술적 요소를 도입한 4개의 문항(STA)과 기술적 상황에 예술적 요소를 도입한 문항(TA)으로 이루어져 있다. 특히, TA는 3개의 문항(과학 및 일상생활과 관련된 문항, 창의적 설계)으로 이루어져 있다. 대구시 소재 고등학교 3학년 학생 60명(남:39명, 여:21명)을 대상으로 STA에 대한 문제해결 과정을 살펴보았으며 상세한 분석을 위해 이 학생들 중 4명을 추출하여 회상면접법을 이용하여 면담도 실시하였다. 또한, STA에 대한 분석 결과를 기반으로 TA를 제작하여 위의 학생 4명을 대상으로 문제해결 과정을 살펴보았으며 위와 마찬가지로 면담도 실시하였다. 연구 결과는 다음과 같다. 첫째, 학생들은 과학적 상황을 예술적 상황과 기술적 상황보다 많이 선택하였으며 그 이유는 빠른 시간 내에 문제를 해결하기 위해 문제의 길이가 짧은 상황을 선호하기 때문인 것으로 나타났다. 둘째, STA의 예술적 상황과 기술적 상황을 과학적 상황보다 흥미롭지만 어렵게 느끼는 것으로 나타났으며 TA의 예술적 요소를 도입한 기술적 상황도 과학적 상황보다 흥미롭게 느끼는 것으로 나타났다. 셋째, 학생들은 STA에서 주어진 상황에 관계없이 문제해결에 필요한 핵심적 과학지식을 사용하여 비교적 간략하게 문제를 해결하는 경향이 있는 것으로 나타났다. 이는 학생들의 문제해결 과정이 반복학습에 의해 정형화되었을 가능성이 있음을 의미한다고 볼 수 있다. STA의 모든 상황에서 논리적 사고와 정교성은 나타났으나 독창성은 두드러지지 않았고 통합적 사고는 나타나지 않았다. 넷째, TA의 과학과 관련된 문항에서는 위와 유사한 결과가 나타났으나 일상생활과 관련된 문항의 경우 학생들은 일상생활을 기반으로 서술하였으며 독창성이 나타났으며 특히, 창의적 설계에서는 학생들의 독창적인 아이디어와 통합적 사고가 나타났다.

Environmental differences across countries such as socio-cultural, political, economic, and technological differences require business strategies of multinational corporations to vary business practices across regions. Despite the keen awareness of the necessity for strategic adaptation to local context, IS management and strategy tend to remain similar across countries. One of the reasons is to maintain the stability and compatibility of information technology infrastructure. After a careful observation of retail business practice, this study finds IS strategy should also be highly responsive to the local context. This study shows how information resources including systems architecture, processes, human resources, and national context are interlinked together. Despite global excellence in general systems management, failure in such alignment can be a serious problem in extending competitive advantages across regions. This study aims to reveal issues to be taken care of in order to accomplish global technological alignment. Results of this study provide senior management with guidelines and a framework for aligning IT with regional strategic thrust that can improve local responsiveness of multinational companies.

The study is based on the technology-organization-environment (TOE) model which, attempted to determine the factors that are going to influence ICT adoption. The proposed research model evaluates the interplay among technological context (IT infrastructure, system security, and user capacity), organizational context (top management commitment, and innovations strategies), environmental context (quick response to the external agencies, interactive network infrastructure, and competitive pressure) and ICT adoption (productivity growth, organizational change, and competitiveness). Data were collected from 243 senior executives of full member firms of the Bangladesh Garments and Manufacturers Association (BGMEA) of examining the relationships among the constructs in the proposed framework utilizing structural equation modeling (SEM). The analysis of TOE factors revealed that environmental, organizational, and technological factors have a significant impact on the successful implementation of ICT tools. The study also discusses implications for management practitioners.

It was already realized at a current technological level of home network systems that the systems recognizes a user's simple order and carry out the order in the ubiquitous computing environment. However home is not a simple environment consisting into a large number of family members, so various order and situation would be needed accordingly. From now on we need to reach the technological level to infer that how is the user's behavior patterns and what kinds of service is the fittest to user who belong to the ubiquitous computing environment by using the result of the context interpreter. In this regards, active inferred-model needs to be suggested upgrading user's command into one step more higher level than the simple one adapting diversified feature. This study would like to suggest this active model recognizing context, which is user's environmental information applying basic network and inferring Context-based Service that user wants through the recognized result This study proposes a new method that can infer the user's desire in ubiquitous computing environment. First of all, we define a context as user's information of ubiquitous computing environment situation that user belongs to and we classify the context into 4W1H(Where, Who, When, What) formats. We construct Bayesian network and put the factor of context use as Bayesian network nodes. As a result, we can infer the user's behavior pattern and most proper service for user in the intelligent space from the probabilistic result of Bayesian network.

Present computing power and enhanced technology is progressing at a dramatic rate. These systems can unravel complex issues, assess and control processes, learn, and-in many cases-fully automate production. There is no doubt that technological advancement is improving many aspects of life, changing the landscape of virtually all industries and enhancing production beyond what was thought possible. However, the human is still a part of these systems. Consequently, as the advancement of systems transpires, the role of humans within those systems will unavoidably continue to adapt as well. Due to the human tendency for error, this technological advancement should compel a persistent emphasis on human error reduction as part of maximizing system efficiency and safety-especially in the context of the nuclear industry. Within this context, as new systems are designed and the role of the human is transformed, human error should be targeted for a significant decrease relative to predecessor systems and an equivalent increase in system stability and safety. This article contends that optimizing the roles of humans and machines in the design and implementation of new types of automation in nuclear facility systems should involve human error reduction without ignoring the essential importance of human interaction within those systems.

The transformation of sector system in Information and Communications Technology (ICT), a prominent character in sector system, has been paid much attention in innovation theory with rapid change in information technologies and technological environment. In this context, we explore how Sectoral Innovation System (SIS) in ICT has been transformed since 1970 by employing US patent data and Proxy variables which measures the basic elements for SIS and its technological characteristics. By utilizing patent data, it is demonstrated that technological regimes, key links and Schumpeterian patterns of innovation in overall ICT sector have drastically transformed over the last three decades. We also reviewed how changes of knowledge bases and technological characteristics driving forces of dynamics in ICT help heterogeneous agents interact with environmental factors (Industrial structure and institutions), leading to industrial or economic growth and its dynamics in the historical perspective over ICT sector (Telecommunication, Computer and Semiconductor). Consequently, our research shows clearly that Schumpeterian patterns of innovation have shifted from Mark I to Mark II in ICT. Our study also provides a glimpse picture of dynamics patent data.

기술혁신은 대기업뿐만 아니라 중소기업에게도 매우 중요한 도전과제 중 하나이다. 본 연구는 중소기업 상황에서 기술협력과 기술혁신 성과 간의 관계에 흡수역량이 어떤 역할을 하는 지를 실증하는데 초점을 둔다. 이 목적을 달성하기 위해 한국의 제조업 중 종업원 수 300명 미만의 중소기업을 대상으로 266개 표본을 통해 계층적 회귀분석을 수행한 결과, 기술협력 방식을 다양하게 활용할수록 기술혁신 성과가 통계적으로 의미 있게 높아지는 것으로 나타났다. 또한 흡수역량의 구성개념 중 지식실현역량에 기초한 역량이 중소기업 상황에서 기술협력 원천과 기술협력 방식이 기술혁신 성과에 미치는 영향을 더 강화시키는 것으로 검증되었다. 이러한 분석결과를 토대로 중소기업이 과도한 기술협력 원천을 활용하는 것은 기술혁신 성과를 향상시키는데 오히려 도움을 주지 못하기 때문에, 기존 지식과 결합시켜 새로운 지식을 창출할 수 있는 역량을 구축하는데 집중적인 관리 노력이 필요하다는 시사점을 도출하였다.
