최근에 일반적인 고분자 재료의 특성을 보유하며 본질적으로 전기전도성을 띠는 고분자 재료들이 발견되어 이러한 고분자 재료의 응용에 대한 연구가 광범위하게 수행되어 왔으며, 특히 전기전자 산업의 급속한 발전으로 그 중요성이 더욱 커지고 있다. 그 중에서도 본질적 전기전도성 고분자인 폴리피롤 (PPy)은 합성이 쉽고 전기전도도와 안정성이 우수하며, 좋은 기계적 특성과 전기적 안정성 그리고 광학특성을 가지고 있어서 여러 응용분야에서 연구가 진행되어 왔다[1,2]. (중략)

As the results of studies based on the Russian Activities-Oriented Theory, the gifted students in many fields have common insights for the true nature of the problem, or the actual state. From Russian Activities-Oriented Theory of view, gifted students have the ability to discern the essential elements involved in each actual state and change of state of things, and to solve the problem, based on these elements. Enhancing these abilities of the students, the educator can develop the average student into a gifted one. This study result of the Russian specialist suggests the possibility of a stream of education that can develop gifted students. Hence, this paper discussed the points and processes of formation of the Russian Activities-Oriented Theory, and inquired on what is the true nature of the problem or the meaning of actual state and how it affects the studies of the student. The paper also investigated the actual conditions of wrong learning about some mathematical concepts and discussed the role of insights to the true nature of the problem in the learning process of the student.

This study is an empirical study to examine the effect of the characteristics of service nature of Korean small and medium manufacturing firms on organizational innovation. It is essential to know service in order for Korea, which has a strong image as a fast follower, to enhance the competitiveness of Small and Medium size Manufacturing firms. By analyzing the service characteristics phenomenon, it is possible to understand the service nature characteristics and to strengthen the capacity to meet them. In order to gain a new resource while achieving organizational innovation, the manufacturing industry can produce new demand for the main products with competitive advantage. The characteristics of service nature are derived from relationship, equality, interactivity, and experiential value. In order to enhance the competitiveness of small and medium size manufacturing firms, core competencies required for organizational innovation are set as dynamic competencies, and to prove it. The dynamic capacity was found to affect the relationship, interactivity, and experience value. It is proved that it is an important factor to promote organizational innovation as a capability to identify and actively utilize organizational innovation opportunities ahead of competitors in a rapidly changing environment. It is needed to confirm that large corporations, midsize companies, and overseas companies can achieve the same results.

This thesis, centered on J. Locke and W. v. Humboldt's concept of language, is written for the purpose of illuminating their view of language and investigating the relationship between a matter of language and that of thought. First, Locke considers language was to be the great instrument and common tie of society. And language consists of words, and words are signs of ideas. Locke's discussion in language is shaped by his belief that these conditions of the transference of knowledge were in his time commonly unsatisfied, especially in two domains. First, there was no agreed classification of 'substance' based on careful observation and experiment. Second, the ideas associated with the names of mixed modes often varied both in the usage of different people and in that of the same person at different times. But Humboldt deals with 'the diversity of the structure of human language' and deals with it in respect of 'its influence on the spiritual development of mankind.' According to his theory, a language is not work(ergon) but an activity(energeia). Its true definition may therefore only be genetic. It is after all the continual intellectual effort to make the articulated sound capable of expressing thought. In short, he conceives of language as a particular 'intellectual effort'.

The intrinsic flame retardant and heat resistant polymers such as PQXS [poly( quinoxaline )sulfide], PIQS [poly(isoquinoline)sulfide] and PQS [poly(quinoline)sulfide] were synthesized from 2, 3-dichloroquinoxaline, 1, 3-dichloroisoquinoline and 4, 7-dichloroquinoline. They were characterized by FT-IR, UV/Vis spectroscopy, DTA and elemental analysis. The melting point above $350^{\circ}C$ of the polymers show higher than that of the heat resistant PPS polymer(mp. $295^{\circ}C$), In the LOI test, the polymers exhibit an intrinsically high flame retardant property having the LOI values in the range of 41~42. The vertical burning test for the polymers also show an UL 94 V-0 performance.

The current research investigates the strategies for fostering service industries from the service's nature perspectives. Because the service industry is broad and heterogeneous in nature, if service's nature is not considered in building strategies for developing service industries, it would have a limited perspective, and thus, it would be difficult to foster large growth in service industries. In addition, not considering service's nature would not encourage synergy among service sectors nor encourage innovative development among individual sectors. Therefore, we need to understand that different service sectors are all under the umbrella for service industries, and consider the service's nature. The current research considers the service's relational, bidirectional, horizontality, and harmonization nature of services, and also, intangibility, inseparability, heterogeneity, perishability were considered in suggesting strategies for fostering service industries. These results can be used to developing governmental policies for developing service industries.

지하공간에서의 화재는 반밀폐 공간이라는 특수성으로 일단 화재가 발생할 경우 대구지하철화재 참사와 유사한 대형참사로 발전된 가능성은 상존한다 지금까지의 방재계획은 화재발생 가능 범위 내를 기준으로 실시되어 왔으나, 테러와 같은 비정상적 화재발생에도 대처가능한 선까지 그 범위를 넓히고 있는 세계적 추세이다. 또한, 지하철은 다른 구조물과 비교하여 화재발생시 화재진압 및 인명구조에 본질적으로 취약한 구조적 특성을 내포하고 있다.(중략)

본 연구는 지리교육에서 이루어지는 지역에 대한 학습 내용을 구성하기 위한 연구이다. 본 연구의 출발점은 우리나라 교육과정에 따라 진행되는, 지역에 대한 학습이 가지는 문제점과 지역에 대한 개념 형성과정에 작용하는 학생들의 지역 인식 특징에 대한 관심이었다. 학생들의 지역에 대해 인식 조사 과정에서 중간적 수준의 지역을 설정할 필요성을 발견하였다. 따라서 본 연구에서 제안하는 지역에 대한 학습의 틀은 지역의 본질적 특성을 바탕으로 교육의 주체인 학생과 교사의 인식이 반영된 내용으로 구성되었다. (중략)
