  • The purpose of this study was to review the studies related to concept learning forcusing on the meanings, kinds, and characteristics of concepts. Then the characteristics of the concepts were analyzed in the three positions: metaphysics, epistemology, and psychology. It was identified that the word 'concept' were confused with the other words such as conception, construct, idea, notion, identity. It was also found that researchers defined the concepts by the use of various meanings. The instructional strategies for scientific concepts were also analyzed in this study. The study found that the instructional strategies for concept learning were developed according to the views about the nature of concepts. Described on the paper are three types of instructional models for science concepts suggested by constructivists as follows: concept formation, concept differentiation, and exchange. They developed the models based on the current research on the misconceptions of major scientific concepts.

  • Students' concepts of scientific phenomena have become a point of focus in science education research. This study investigated into developmental process and mechanism of the students' respiration concept through a cross-age study. This study utilized the 1st, 3rd, 6th grade elementary students to find out changes in student's understanding of the concept of respiration. The 1st and 3rd grade level students were interviewed what the respiration mean and whether each of living things respires, etc. The 6th grade students were interviewed and tested. Respiration is a word that students come across often in everyday life. It was found that they were more likely to associate respiration with its more common concept of breathing or gas exchange as opposed to its more scientific definition as the process in which nutrients are oxidized to provide energy. This trend didn't improve as they advanced grade. This is an indication that the knowledge system of student is split into a generic knowledge system and scientific knowledge system. Understanding of concept increased and differentiated across grade levels but that understanding was limited. They overcome their tendency to base their understanding of respiration on their understanding of human phenomena and learn to integrate their understanding of biological phenomena through a one organ - one role type of logic. They also intuitively explain everything based on their own experience.

  • This study explored different concepts by handing out the questionnaires asking the 6 students of the second year of junior high school who had no lesson on cycle "which words related to cycle are suggested?" In regard to the stimulation of the word 'cycle', students relate it to different fields that they learn at school such as biology, environmentology, and earth science. The analyzed results from the answers by students are as follows. First, it resulted in from analysis on the questionnaire and the half-structured interviews that students were unable to expand the concept of cycle to the scientific concept, and perceived it fragmentarily. Secondly, their understanding on the system of the earth was low and they understood the concept of cycle with a unilinear thought rather than a systematic thought. Therefore, we need to synthesize the students' unilinear thoughts on cycle shown through this study and an effective educational strategy for their continuous, systematic thoughts, is essential.

  • The frequency analysis of scientific terms using bibliographic information is a simple concept, but as relevant data become more widespread, manual analysis of all data is practically impossible or only possible to a very limited extent. In addition, as the scale of oceanographic research has expanded to become much more comprehensive and widespread, the allocation of research resources on various topics has become an important issue. In this study, the frequency analysis of scientific terms was performed using text mining. The data used in the analysis is a general-purpose scholarship database, totaling 2,878 articles. Hypoxia, which is an important issue in the marine environment, was selected as a research field and the frequencies of related words were analyzed. The most frequently used words were 'Organic matter', 'Bottom water', and 'Dead zone' and specific areas showed high frequency. The results of this research can be used as a basis for the allocation of research resources to the frequency of use of related terms in specific fields when planning a large research project represented by single word.

  • Today, our indoor space requires a user-centered considering design that satisfies even human sensitivity. The word 'sensitivity' is being frequently used in the design market recently and this means that consumers are becoming more sensitive. For this reason, the characteristics of Toyo Ito's architecture, which are innocent due to its natural structure and materials, are suggested as a sensitive lighting stand design which can relieve users' stress from daily life and bring a psychological stability. As such, sensitivity lighting can create a lighting environment that considers consumers in various spaces along with the development of new scientific technologies and develop in a new direction of aesthetical beauty and eco-friendly area. In this study, a natural and sensitive lighting stand is suggested where a variety of digital art techniques of LED are applied based on formative characteristics of relationship, one of Toyo Ito's architectural concept factors. Such sensitivity lighting designs can not only realize a type-free design but also suggest a creation of the atmosphere which is close to nature.

  • 흔히 조셉 슈왑은 20세기 과학교육의 가장 중요한 키워드라 할 수 있는 과학탐구론의 주창자로 여겨진다. 본 연구는, 문헌조사의 방법에 기초하여, 슈왑의 과학교육자 및 교육학자로서의 그의 생애를 간략히 요약하고 또 주요 쟁점들을 중심으로 그의 과학 및 과학교육에 대한 사상들을 되돌아 보았다. 뛰어난 과학자로 출발하였다가 나중에 교육의 활동에 참여하였던 1950년까지의 다른 유명한 과학교육자들과 같이, 슈왑은 본래 유전학 전공의 과학자였으나 이후 교육개혁, 교육과정 연구, 과학교육에 집중하였다. 그의 학문적 관심은 다양한 분야에 걸쳐 폭넓은 것으로서, 생물학과 과학으로부터 역사, 철학, 교육에 걸치는 것이었다. 그의 과학탐구 이론의 핵심은 '과학을 과학답게 가르치는' 것이며 이를 이루는 가장 좋은 방법은 '과학을 탐구로 가르치는' 것이다. 하지만 그는 '과학을 탐구로 가르치기' 위해서는 '탐구로서의 과학'과 '탐구로서의 교수' 그리고 '안정적 탐구'와 '유동적 탐구'에 대한 섬세한 개념적 구분이 필요하다고 주장한다. 과학교육과 교육학 일반에 걸친 그의 많은 아이디어들은 자신의 과학탐구의 개념에 기초하고 있으며, 이는 과학의 다양성, 교과서, 교육과정, 교사의 역할 등 다른 그의 주요 개념들의 기초가 된다. 요약하자면, 슈왑은 과학교육의 합리적 개혁을 이끌었던 학자로 특징지어질 수 있으며, 여기서 합리적 개혁이란 과학교육의 본성과 그 지향점을 파악하고 이를 위하여 해당 학문 영역에 대한 구체적이고 실제적인 안내를 통해 실질적인 변화를 이끌고자 하였다는 의미이다. 그럼에도 불구하고, 일부 그의 주요 아이디어는 그 추종자들에 의한 상당한 왜곡을 지닌 채 후대에 전해지고 있다.

  • Today, SPA fills many of the same needs as they did thousands of years ago, including relaxation, wellness and stress relief by incorporating many of the same methods embraced by the ancients such as a multitude of hydrotherapy treatments, thalassotherapy and massage therapy, one of the most widely used SPA treatments. The definition is as follows: SPA is entities devoted to enhancing overall well-being through a variety of professional services that encourage the renewal of mind, body and spirit. It was from here that the concept of modernday SPA evolved, incorporating full health and beauty services along with sport, aquatic and rest facilities. Todays SPA, a absolute concept, is being specialized and spread as fast as undefinable just in a word. Thalassotherapy, a kind of SPA therapy, contains minerals and trace elements. Born more than 4,000 years ago in ancient Egypt, thalassotherapy comes from the Greek words for thalasso(sea water) and therapeia(to heal). Thalassa was the Greek personification of the Mediterranean Sea that surrounded them and gave them so much of their sustenance. It helps to nourish, hydrate and refine skin texture and also eliminate metabolic waste and toxins in the body. Thalassotherapy is recommended for post-natal and postsurgery recovery period, chronic fatigue, circulatory problems, cellulite control and dermatological problems. It's also possible to enjoy the thalassotherapy SPA as a day guest. Be sure to try the jansu massage, given in the heated sea water pool. As a trained therapist gently whisks clients through the womb-warm water, clients can practically feel the toxins leave their body. Many women from all over the world have been kept up beautiful skin with applying thalassotherapy to their faces and bodies since long times and these days in France, they are getting great curative clinical effects from renovative and scientific technological combination. Thus thalassotherapy will be absolutely ultimate form of natural healing which can keep and recover human's health and beauty.

  • The words which appeared in my theoretical study and work are image transformation to digital painting, simulation, heterologie and transfiguration, etc. Firstly, let's look into 'digital era' or 'new media era'. Nowadays, the image world including painting within the rapid social and cultural change, which is called as digital era, is having the dramatic change. Together with the development of scientific technology, large number of events which was deemed to be impossible is happening as real in image world Moreover, these changes in image world is greatly influencing to our life. The word which compresses this change of image world and shows is 'digital'. Digit, which means fingers in Latin, indicates separately changing signal, and to be more narrow, it indicates the continual signal of '0' and ' 1' in computer. The opposite word is 'analogue'. As analogue is the word meaning 'infer' or 'similarity', it indicates the signal or form which continuously changes along the series of time when it is compared to digital. Instead of analogue, digital is embossed as a major ruler along the whole area of our current culture. In whole culture and art area, and in whole generalscience, digital is appearing as it has the modernism and importance. The prefix, 'digital', e.g. digital media, digital culture, digital design, digital philosophy, etc, is treated as the synonym of modernism and something new. This advent of digital results the innovative change to the image world, creates the new beauty experience which we could not experience before, and forecasts the formation of advanced art and expansion of creative area. Various intellectual activities using computer is developing the whole world with making the infrastructure. Computer in painting work immediately accomplishes the idea of painters, takes part in simulation work, contingency such as abrupt reversal, extraction, twisting, shaking, obscureness, overlapping, etc, and timing to stimulate the creativity of painters, and provides digital formative language which enables new visual experience to the audience. When the change of digital era, the image appeared in my work is shown in 'transfiguration' like drawing. The word, 'transfiguration' does not indicate the completed and fixed real substance but indicate endlessly moving and floating shape. Thus, this concept is opposite to the substantial consideration, so that various concepts which is able to replace this in accordance with the similar cases are also exist such as change, deterioration, mutation, deformity of appearance and morphing which is frequently used in computer as a technical word. These concepts are not clearly classified, and variably and complicatedly related. Transfiguration basically means the denial of "objectivity' and '(continual) stagnation' or deviation from those. This phenomenon is appeared through the all art schools of art ever since the realism is denied in the 19th century. It is called as 'deformation' in case of expressionism, futurism, cubism, etc, in the beginning of the century, which its former indication is mostly preserved within the process of structural deviation and which has the realistic limit which should be preserved. On the contrary, dramatic transfiguration which has been showing in the modern era through surrealism is different in the point that dramatic transfiguration tends to show the deterioration and deviation rather than the preservation of indicated object. From this point, transfiguration coming out from morphing using computer deteriorates and hides the reality and furthermore, it replaces the 'reality'. Moreover, transfiguration is closely approached to the world of fake or 'imaginary' simulation world of Baudrillard. According to Baudrillard, the image hides and deteriorates the reality, and furthermore, expresses 'not existing' to 'imaginary' under the name of transfiguration. Certain reality, that is, image which is absent from the reality is created and overflowed, so that it finally replaces the reality. This is simulation as it is said by Baudrillard. In turn, Georges Bataille discusses about the image which is produced by digital technology in terms of heterologie. Image of heterologie is the visual signal which is established with the media. Image of media is to have the continuous characteristics of produce, extinction, and transformation, and its clear boundary between images becomes meaningless. The meaning of composition, excess, violation, etc of digital image is explained to heterological study or heteologie suggested as important meaning of Georges Bataille who is a heretic philosopher. As the form and image of mutation shows the shape in accordance with mechanical production, heterologie is introduced as very low materialism (or bas materialisme), in this theory. Heterologie as low materialism which is gradually changing is developing as a different concept and analysis because of the change of time in the late 20s century beside high or low meaning. Including my image, all images non-standardizes and transforms the code. However, reappearance and non-standardization of this code does not seem to be simple. The problem of transformation caused by transfiguration which appears in my digital drawing painting, simulation, heterologie, etc, are the continual problems. Moreover, the subject such as existence of human being, distance from the real life, politics and social problems are being extended to actual research and various expressing work. Especially, individual image world is established by digital painting transfiguration technique, and its change and review start to have the durability. The consciousness of observers who look at the image is changing the subject. Together with theoretical research, researchers are to establish the first step to approach to various image change of digital era painting through transfiguration technique using our realistic and historical image.
