  • 과학교육에 있어 지금까지 개발된 수업모형은 마치 과학의 모든 목적을 달성시켜줄 것 같지만 실제 교육현장에 적용해 보면 기대하던 효과를 얻지 못하는 경우가 많다. 수업의 효과를 극대화하기 위해서는, 어느 한가지 방법만을 고수하는 것보다 개발된 수업모형을 유연성 있게 활용 할 수 있는 교사의 수업전략이 필요하다. 본 연구는 개념도와 순환학습을 통합한 수업이 개념도를 활용한 수업이나 순환학습과 비교하여 고등학생들의 학업성취도 및 과학적 탐구능력, 과학에 대한 태도에 어떠한 영향을 주는지 알아보는데 그 목적이 있다. 연구대상은 고등학교 2학년 여학생 324명으로, 개념도-순환학습 집단, 개념도 활용 집단, 순환학습 집단, 전통적 수업 집단의 4집단으로 나누어 수업하였다. 연구 단원은 고등학교 과학의 '생식과 유전' 단원으로 약 10주간 10차시에 걸쳐 수업처치 하였다. 수업처치 전, 후에 학업성취도 검사와 과학적 탐구능력, 과학에 대한 태도 검사를 실시하였고, 연구결과는 공변량 분석 (ANCOVA과)과 사후 검증(Duncan test)으로 분석하였다. 개념도-순환학습은 학생들의 과학 학업성취도를 향상시키는데 전통적인 수업보다 효과적이었고(p< .05) 그 효과면에서 개념도를 활용한 수업보다 떨어지지 않았다. 성취 수준이 상위와 중위 학생들은 수업방법에 따라 학업성취도에 차이를 보이지 않았으나, 하위학생들은 개념도를 활용한 수업이 가장 효과적이었다(p< .05). 개념도-순환학습은 학생들의 과학적 탐구능력을 신장시키는데 개념도를 활용한 수업이나 전통적 수업보다 효과적이었으며(p< .05) 그 효과 면에서 순환학에 떨어지지 않았다. 성취수준이 상위인 학생은 수업방식에 따라 과학적 탐구능력에 차이를 보이지 않았으나, 개념도-순환 학습은 중위와 하위 학생들의 과학탐구능력 향상에 순환학습 만큼 효과적이었다. 개념도-순환학습은 학생들의 과학에 대한 태도를 향상시키는데 전통적 수업보다 효과적이었으며(p< .05) 그 효과 면에서 개념도 활용 학습이나 순환학습에 뒤지지 않았다. 따라서 개념도 순환 학습은 모든 학생들의 수준을 고려 할 때 학생들의 학업성취도를 향상시키고, 과학적 탐구능력을 신장시키는데 개념도 활용학습이나 순환학습을 단독으로 적용하는 것보다 긍정적이라고 할 수 있다.

  • This study identifies the concept of a digital convergence paradigm, which deals with the relationship among convergence and consumer participation, digital contents services, and the culture of consumption (web 2.0). This research was conducted using a quantitative method involving focus group interviews (FGI) and literature reviews. This research examines the relationship between convergence and consumer participation and the adoption of a concept of "convergence culture", which is categorized as "collective intelligence" and "intellectual community participation". The role of the consumer has changed from one of a "consuming consumer" to that of a "collaborating consumer" and finally to the concept of a consumers as the originator of a new consumption culture. In the study, the consumption culture of web participants indicated the characteristics of funology, self-expression, life-catching, quick-tempered, immersion(arousal), sharing culture, multitasking, and cyber justice. The recognition level of networking on the "digital convergence" of the consumer was identified as that of the combination of IT(information technology); product and multi-services or alliance of industry groups(telecom, broadband, IPTV service); or the use of one source with multiple devices.

  • Contemporary architecture is philosophy and art, and science are different that holds the architecture of human thought and behavior based on a variety of physical space. In addition, the technology is used by the new media graphics, lasers, LED, which were possible only in imagination, using tools such as the time-space of the potential for explosion. In particular, it was found in the spacial color of atypical using the nature of light. Such these architecture is space people actively experiencing a sense towards the expansion of its place. Therefore, the study purpose is to explore the Steven Holl's spacial colors to utilize the space is important to the possibility of light. He prefers the connection to the invisible world is inferred from the visible world and other space. He thoughts an idea linked to the concept watercolors which is a tool that holds to the notion of the flexibility of light and shadow. Concept watercolor is the idea space, establish space, recombinant space, and the growthy space. These have shown the no fixed spacial color cause of the combination of the different tones according to the characteristics of the mixed-color development of a concept watercolors demonstrated the spacial color of the replacement. That is to establish a parody of the works light blending spacial color.

  • Objectives: This study is to understand and develop Acupuncture treatment in Korean Medicine(韓醫學). Methods : Firstly, the definitions of Acupuncture Prescription(鍼 處方) and Methods of Acupuncture Therapies(鍼法) were clarified. Secondly, the results from the researches of previously existing Acupuncture Prescriptions(鍼 處方) were analyzed. Results & Conclusions : Acupuncture Prescription(鍼 處方) represents the results achieved from combining Acupuncture Points(腧穴) according to the symptoms of diseases. Methods of Acupuncture Therapies(鍼法) denote methodologies for proposing Acupuncture Prescriptions(鍼 處方) which were accomplished by combining Acupuncture Points(腧穴) based on a specific theory. The existing methods of combining Acupuncture Points(腧穴) derived from the analysis of Acupuncture Prescription (鍼 處方) have a meaning in suggesting a direction for acupuncture treatments. However, deficiencies still exist to restore the absence of universality and objectivity in acupuncture treatment. Researches on Methods of Acupuncture Therapies(鍼法) based on the principle are required accordingly. The concept of hierarchy exists in Acupuncture Prescription(鍼 處方) and it ranks Acupuncture Points(腧穴) as primary and secondary according to the indications of the Acupuncture Points(腧穴). Since there is the time difference in needling process, the concept of hierarchy is fulfilled through the needling procedure.

  • Objectives The purpose of this study is to understand the influence of Daesihog-tang on Taeeum-in's patholoy and prescription in "Donguisusebowon" of Sasang Constitutional Medicine. Methods The pathologic condition in which Daesihog-tang used and the relevant herbs and prescriptions in "Sanghanron", "Donguibogam", "Dongmuyoogo haedong", "Chobongwon", and "Donguisusebowon". Results and Conclusions 1. Daesiho-tang in "Sanghanron" was used to the symptom of Yangmyung disease merging with Soyang disease. In "Donguibogam", its indications were mainly used to the severe fever-symptom of Yangmyung disease and expanded to Onbyeong and so on. 2. The concept of Daesiho-tang in "Donguibogam" was changed into Hwanggeumdaehwang-tang in "Chobongwon", which can be used to treat Onbyeong with heat-dysenteric diarrhea, and severe fever of Taeeum-in. 3. The notion of combination between Daehwang and hwanggeum used in "Dongmuyoogo haedong" and "Chobongwon" was connected to Chungmongsukgondamhwan or Jogakhwanggeumdaehwang-tang in "Chobongwon". Especially, Jogakhwanggeumdaehwang-tang for Yeokkigammo and severe constipation was formed while the concept of Onbyeong in Hwanggeumdaehwang-tang' merged with the usage of Jogak and Daehwang or Yisunggugo-hwan. 4. Jogakhwanggeumdaehwang-tang influenced on the usage of Jogakdaehwang-tang for Yangdok and Onbyeong, while the usage of Chungmongsukgondamhwan was not found in "Donguisusebowon". 5. As a result, Daesiho-tang may be presented without usages for a specific patholoy in "Donguisusebowon" because it indirectly influenced on the concept of Yangdok and Onbyeong of Taeeum-in, and the formation of Jogakdaehwang-tang in "Donguisusebowon".

  • In the present study, the fracture toughness of U-shaped notches made of aluminum alloy Al7075-T6 under combined tension/out-of-plane shear loading conditions (mixed mode I/III) is studied by theoretical and experimental methods. In the experimental part, U-notched test samples are loaded using a previously developed fixture under mixed mode I/III loading and their load-carrying capacity (LCC) is measured. Then, due to the presence of considerable plasticity in the notch vicinity at crack initiation instance, using the Equivalent Material Concept (EMC) and with the help of the point stress (PS) and mean stress (MS) brittle failure criteria, the LCC of the tested samples is predicted theoretically. The EMC equates a ductile material with a virtual brittle material in order to avoid performing elastic-plastic analysis. Because of the very good match between the EMC-PS and EMC-MS combined criteria with the experimental results, the use of the combination of the criteria with EMC is recommended for designing U-notched aluminum plates in engineering structures. Meanwhile, because of nearly the same accuracy of the two criteria and the simplicity of the PS criterion relations, the use of EMC-PS failure model in design of notched Al7075-T6 components is superior to the EMC-MS criterion.

  • Since the 20th century, there has been a growing interest in the new concept of fractals, a combination of mathematics and art, and the attempt to study the creative spatial aspects of the concept is being made. The purpose of this research is to examine artistic characteristics of fractal dimension and then analyze the types of fractal dimensions expressed in the fashion. Previous literature on fractals and dimension, and visual data on art and fashion collected over the Internet were used for analysis. Fractal dimension refers to the spatial concept of structural dimension of geometrical self-similarity. An analysis of the types of fractals seen in fashion revealed spatial expansion, the repetition in continual figures, superposition accordant to different sizes, and shades of different shapes. The aesthetic characteristics of fractal dimension appearing in fashions were examined based on analyses of fractal dimension types; the inherent characteristics of self-similarity, superimposition, and atypicality were found. Results obtained from this study are expected to be used as basic materials for the application of the design of fractal dimension into various perspectives of fashion.

  • This paper suggests a model of Living & Learning Nation as a new ploicy framework. It is a combination of Living Nation and Learning Nation. Living Nation model takes the nation as a living entity composed of spirit, resource, and communication : it grows but healthy and balanced growth is needed, its organs are closely connected, it has a circulation system, the 'spirit' factor plays the central role, etc.. Learning Nation model is a national level version of learning organization concept. The model defines new perspectives on the objectives, span of means, and the role of government in S&T policy. Therefore, the model can be used to give new insights to policymakers of developing countries facing the knowledge-based economy.
