In this modern world of drastic change, folding architecture was an alternative that offered a novel architectural insight. Today, the folding technique is being used above and beyond architecture, spreading to fashion, lighting, medicine, etc. Especially in the interior space design field, the folding technique is in the limelight as an alternative to create an original space for modern society. However, research and experiments into folding mainly remains at philosophical interpretation or architectural examples, and even these were mostly before the 2000s. Therefore, the present study determined it necessary to look deeply into the post-2000s folding technique focusing on interior space. In this paper, 33 cases of indoor space where folding technique appears are derived, and classified them again by use. The folding technique which was the first step of Sophia Vyzoviti's experiment on her book, "Folding Architecture" was extracted and used as the framework. We summarizes the range of application of folding techniques (interior space in general, floor, wall, ceiling, etc.) and major folding techniques by combining photographs, drawings, and descriptions of the works of the architects. This paper summarizes the characteristics of the space described comprehensively, and draws out the spatial characteristics of the modern interior space where the folding technique appears.

이 논문은 오늘날과 같은 다매체시대에서 중요한 화두가 되고 있는 생태학을 바탕으로 한국문학, 특히 시조와 현대소설에서의 자연친화적이고 자연동화적이 상징물이 어떠한 의미로 나타나고 있으며, 어떻게 생태학적 상상력으로 형상화되고 있는가를 고찰하면서 시대와 장르간의 통시적 통합적 사고를 도출하려는 데 그 목적이 있다. 한국문학, 특히 우리의 시조에서는 자연을 주거공간으로 생각하고, 인간과 자연의 불가분리의 관계에서 자연친화적이며 자연동화적인 삶을 노래하고 있다. 그리고 현대소설에서도 시조에서 나타난 것과 마찬가지로 은유나 상징의 자연공간이 생태적 상상력으로 형상화되어진다. 따라서 이 두 장르는 통시적 통합적 관계에서 소통이 가능하다고 본다. 문학생태학과 장르 간 소통을 위한 올바른 방향 몇 가지를 요약하면 다음과 같다. 먼저 문학이 현실에 바탕을 두고 있다는 생각에서 과감히 벗어나 문학생태학적 상상력을 탐색해야 할 것이다. 오늘날 인류가 겪고 있는 환경 위기나 생태계위기도 따지고 보면 진보와 발전이라는 목표를 세워놓고 거기에만 매달려 초래된 결과라고 할 수 있다. 따라서 앞으로의 문학은 녹색의 문학생태학에도 많은 관심을 갖고서 문학생태학적 상상력을 찾아 부단히 움직이는 모습을 보여야 할 것이다. 그리고 우리 문학작품에 두루 나타나고 있는 공통의 자연관과 문학생태학적 상상력을 이제 수용과 창작의 통합의 원리에서 접근해야 할 것이다. 교사와 학생에게 자연과 환경. 생태계의 문제는 현실적이고도 공동적인 주제가 될 수 있다 따라서 자연친화적이고 생태학적 문학작품의 수용과 창작 활동이 문학적 감수성과 상상력을 함양하는 실천적 교육모형이 될 수 있도록 해야 한다. 또한 통시적이며 통합적인 맥락에서 한국문학의 각 장르에 대한 활발한 연구와 모색이 전제되어야 할 것이다 특히 한국문학의 전통적 자연의식을 전승하고 있는 시조의 활성화가 필요하다고 본다 열린 사고를 갖고 시조가 지니고 있는 고유한 특성을 고수하면서 새로운 시대에 적응하는 방법 모색은 더욱 치열하게 전개되어야 할 것이다. 따라서 소설의 장르가 디지털시대의 새로운 문학 환경에서 새로운 정체성을 확보하기 위하여 나름대로의 대응방법을 모색하는 데서 그 하나의 단초를 마련할 수 있을 것이다.

With the advent of the telecommunication era, a mobile phone becomes a necessary communication device in modern society. For silent tactile signal, vibration motors have become one of the generic components in most mobile phones. Conventional vibration motors employ three-phase windings with mechanical brushes for commutation. However, mechanical commutation in these prior arts greatly deteriorates its life span, reliability, and productivity due to structural intricacy. This paper introduces a novel design of solenoid-type vibrators using electromagnetic and mechanical analysis. The proposed vibrators have a simpler structure and longer life span by eliminating wear-prone commutation parts in vibration motors.

Dimethomorph is a novel fungicide with a high level of activity against diseases induced by certain Oomycetes, including fungal populations that are resistant to other products. In several ways, this fungicide illustrates the opportunities and challenges presented by many modern pesticides. The specific mode of action, which affects cell wall formation, is associated with a very high level of performance and low dose rates under field conditions. These low dose rates, combined with a low level of toxicity to non-target organisms present an outstanding safety profile. This same highly-specific mode of action, however, limits the spectrum of activity and suggests the need for a resistance management plan, both of which must be addressed in new product development. In addition, the biological and physiochemical properties of this, and other new products are not adequately described by the traditional classification of fungicides into“protectant”and“systemic”types. These unique profiles provide novel and useful products for disease control.

This paper examines 'an active nihilism' in Suk-je Sung's novels in detail. The focus of this study is formed from the critical mind in a critical perspective that in Korean novels before and after 2000s, characters who embody 'problematic individuals' of $Luk{\acute{a}}cs$ have disappeared and those close to 'active nihilists' has become the mainstream. The most representative example of this phenomenon is Suk-je Sung's novels. 'Active nihilists' in his novels are described as 'ascetics' who mastered various spheres such as 'billiard', 'baduk gambling', 'alcohol', 'dance', and 'book collecting', and so on. In the sense that they reject the transcendental conditions of the modern world and live in the space and time of play in which they can display their passion and potentiality to the maximum, they beings jumping over the 'reality principle'. Also, what they want to repeat is not the endless exchange of labor and capital according to the capitalist system of exchange but rather the repeated existence of their power and passion. This 'anthropology of power and passion' is 'active nihilism' which could be expressed as the 'subject of creating new value' and 'Dionysian affirmation' by Nietzsche. Suk-je Sung's novels sharply prove the stylistic essence of 'a novel' which has to create its own form every time, constantly renewing the narrative style of the past ideal model. In this respect, they are very problematic and his innovation of a form draws the attention. Further, this will certainly be the important object of research in the diachronic dimension of contemporary Korean novel.

The purpose of this study was to examine the uniform image of Korean herbal cosmetic brands amongst Korean and Chinese consumers. This study would enable us to explore a BI strategy to enhance international competitiveness of Korean herbal cosmetics brands. The results were as follows. The key words of BI pursued by Sulwhasoo were dignified, novel, graceful, soft, gaily, natural, Korean, modern, and international. Korean people felt that the uniform was graceful and soft, which accorded with Sulwhasoo BI, but also it was trite and dingy, indicating a negative and opposing image. On the other hand, Chinese people felt that the uniform was dignified, novel, graceful, natural, modern, and international, indicating that it matched with Sulwhasoo BI. In The History of Whoo, the key words of BI pursued by the brand were precious, soft, gorgeous, gaily, and natural. The Koreans felt that the uniform was intelligent, and decent, but conversely, it was also austere and dingy, indicating a negative image. The Chinese felt that the uniform was common, hard, austere, dingy, and unnatural, indicating an opposing image to BI. Finally, a uniform design was developed to improve on its problems, establish The History of Whoo's brand identity, and its brand image. First of all, 'The Quintessence : noble passion' was set up as a developmental concept. The textiles, clothing, and accessories were designed using the symbolic elements from The History of Whoo as a motif. Uniforms were developed for spring, fall, and summer.

Though anatomical and histological investigations on the novel threadlike and corpuscular structures, Bonghan duct(BHD) and Bonghan corpuscles(BHC) of internal organs of rats and rabbits were extensively studied. In this article we introduce the refined method to observe the BHD and BHC on the internal organs of mice. This development is needed because immunohistochemical analysis and other modern biological techniques were mostly applicable only to mice but not to rats and rabbits. We made uses of grazing effect of light as well as discriminating technique of BHD/C from fibrin and take the novel structures, BHD/C on mouse internal organ. The specimens taken were examined by hematoxyline and eosin(H & E) and revealed as novel structures. Our method described herein to take BHD/C characterization of mouse, especially for stem cell related researches.

With the increasing interest in the expression of individuality and appearance of modern people, it is time to conduct research and development of novel hair coloring from various angles. Therefore, taking into account the order of discoloration of hair pigments, we selected a creative and novel emulsion as a novel material for hair coloring, rather than a cosmetic material such as hot water extract using natural products dealt with in previous studies, commercially available hair manicure, and oxidation hair dye for hair. Thus, the change in tensile strength and elongation of hair samples by color was studied. As a result of the study, hair with green emulsion paint had a significantly higher maximum load, maximum stress, maximum elongation and breaking load, breaking stress, breaking elongation values are shown. Maximum in terms of modulus, green emulsion applied hair and the control group were higher in the 0-15s strain and 15-145s sections, respectively, and the tangential modulus value was much higher in the control group than the experimental group hairs in all the 0-145s sections. This study, which analyzes the dynamic changes of hair samples that extend the daily color gamut, will greatly contribute to the development of innovative hair coloring materials in the research and production of hair beauty works, and it is judged that it will also contribute to the development of the beauty industry.

A novel energetic material, 1-amino-1-(2,4-dinitrophenylhydrazinyl)-2,2-dinitroethylene (APHDNE), was synthesized by the reaction of 1,1-diamino-2,2-dinitroethylene (FOX-7) and 2,4-dinitrophenylhydrazine in N-methyl pyrrolidone (NMP) at 110 $^{\circ}C$. The theoretical investigation on APHDNE was curried out by B3LYP/6-311+$G^*$ method. The IR frequencies analysis and NMR chemical shifts were performed and compared with the experimental results. The thermal behavior of APHDNE was studied by DSC and TG/DTG methods, and can be divided into two crystal phase transition processes and three exothermic decomposition processes. The enthalpy, apparent activation energy and pre-exponential factor of the first exothermic decomposition reaction were obtained as -525.3 kJ $mol^{-1}$, 276.85 kJ $mol^{-1}$ and $10^{26.22}s^{-1}$, respectively. The critical temperature of thermal explosion of APHDNE is 237.7 $^{\circ}C$. The specific heat capacity of APHDNE was determined with micro-DSC method and theoretical calculation method, and the molar heat capacity is 363.67 J $mol^{-1}K^{-1}$ at 298.15 K. The adiabatic time-to-explosion of APHDNE was also calculated to be a certain value between 253.2-309.4 s. APHDNE has higher thermal stability than FOX-7.
