  • Today, as individuals show their social identities and reflect their being as the members of society with a culture, an art style and communication function are stood out in fashion photographs. Accordingly, the meanings of images into text are expanded in its interpretative width through the acceptor's various terms. This researcher looked into four theories of both positions on the textuality of language and image, and considered the point of discussion on image of each theory through modern fashion photographs. First, the theory which divides language and image as auditory and visual recognitions in the textuality of language and image is limited from the view it focuses on only one side without considering the ambivalent elements of each field. For the textuality in modern fashion photographs, the observer attempts to turn it into text to give meaning to it as the recognition through five senses conforming to the acceptor's condition. Second, the theory dividing language and image into the text of time properties and spacial properties has limitation in the text, for acceptor's experience of the object appears as the structured form in time and space rather than being defined as two things like time and space. Third, the theory classifying the language and image text into conventional taste and natural taste has limitation from the view that image text is hardly an object of consistent classification in ease of recognition by the code accepted in society. Thus, this can't be fundamental approach for the understanding of the text of decoding trend represented in modern fashion photographs. Fourth, accordingly, this researcher focussed on contextual and arbitrary text of fashion photographs through the theory of Nelson Goodman which discusses image text through the differences in textuality. Basic mechanism of perceiving and recognizing and distinguish image is closely related to habit and custom like language. So, each acceptor perceives the image as a text through arbitrary interpretation obtained by individual, empirical, historical, and educational viewpoints. The textuality of modern fashion photographs aims to widen the range of diverse knowledge and understanding, transcending the regulations of simple function of existing fashion photographs. Consequently, this researcher puts forward the opinion of consistent and diverse follow-up studies on instilling meaning into fashion photographs for the understanding de-regulatory and de-constructive through various senses by avoiding only one sense-dependent fixed and regulatory properties of it.

  • Shewanella putrefaciens DK-1은 그람음성, 통성 혐기성 세균으로 $NO_{3}$, Fe(III), Mn(IV), humic acid와 같은 다양한 전자수용체를 이용한다. S. putrefaciens DK-1의 전자공여체의 이용능력은 제한적이며, lactate나 formate는 좋은 전자공여체로 이용되지만 acetate나 toluene은 이용하지 못하였다. 다양한 전자수용체간의 경쟁을 살펴보기 위해 전자수용체로 Fe(III)와 같이 $NO_{3}^{-}$, $NO_{2}^{-}$를 넣어 주었을 매 Fe(III)의 환원은 저해되었다. 또한 5. putrefaciens DK-1은 전자수용체로 토양에 광범위하게 존재하는 humic acid를 이용하였으며, 환원된 humic acid는 질산염에 의해서 다시 산화되었다. Fe(III) 환원능이 있는 환경 시료를 이용하여 탄소, 질소, 인과 같은 제한 요인이 Fe(III) 환원세균의 활성에 미치는 효과를 조사하였다. 천호지의 저질토와 대호의 농토에 각각 탄소원, 질소원, 인을 첨가해 주었을 경우 S. putrefaciens DK-1과 탄소원을 동시에 첨가해 주었을 때 가장 높은 철 환원능을 보여주었다.
