Over the last 3 years, the global food 3D printing market has grown at an average annual rate of 31.5% and has shown an industry size that reached about U$ 9.46 billion. Food 3D printing technology has the advantage of being utilizable in diverse ranges because it enables free design of existing foods so that foods can be produced according to individuals' tastes and purposes. Many countries around the world are producing food 3D printers to release trial products such as foods employing the advantages of food 3D printing. They are also attempting to apply food 3D printing in various fields such as combat rations, space rations, restaurants, liquid foods, foods for the elderly, diets for patients, and baby foods. Whereas the 3D printing market, which has a high growth potential and is expected to continue to expand in size, is highly likely to become a blue ocean, not only is food 3D printing technology small in South Korea, but also the overall ratio of 3D printing utilization and the scale of the relevant industry are small. This is attributable to the fact that South Korea has problems such as insufficient institutionalization compared to developed countries and delays in the development of standardized domestic materials. Therefore, this paper is intended to inform the necessity of food 3D printing and describe food 3D printing technology and food 3D materials in order to obtain the additional effect of vitalizing the South Korean food 3D printing market.

With the development of media, modern times are actively exchanging cultures and information around the world. Therefore, product development using traditional material, which are Korean cultural heritages, can be said to be another medium that can promote our unique culture to the world. Therefore, this study attempted to develop a product suitable for the modern lifestyle that combines tradition and modernity by investigating and analyzing Korean roof tiles and applying the formative elements identified as a result of the study. Among the types of roof tiles, a Sumaksai, which is located on the front of the roof and stands out for decoration, was selected as the subject of the study, and it was developed by combining it with lighting and plates as an item for modern people seeking a life full of personality. In product development, we tried to express the traditional style as it is by making the most of the elements of the Sumaksai, and the lotus pattern, which was most commonly used in each era when roof tiles were made, was simplified and applied to the product. As the products developed in this way are used in our daily lives, we hope that users' interest in ours will increase, and that the development of various products through research on traditional material can be activated as a way to spread our culture around the world.

The hybridization of carbon nano-materials enhances the efficiency of each function of the resulting structure or composites. Also, the addition of non-carbon elements to nanomaterials modifies the electrochemical properties. Electrodes combining porous carbon nanofibers (CNFs) and metal oxides benefit from the combination of the double-layer capacitance of the CNFs and the pseudocapacitive character associated with the surface redox-type reactions. Consequently, they demonstrate superior supercapacitor performance in terms of high capacitance, high energy/power efficiency and high rate capability. This paper presents a comprehensive review of the latest advances made in the development and application of various metal oxide/CNF composites (CNFCs) to supercapacitor electrodes.

SOFC cell 하나의 전위차는 약1.1V이기 때문에 발전용으로 사용하기 위해서는 수많은 단전지를 직렬로 연결하는 구조가 필요하다. 이러한 stack의 디자인에서 발생하는 문제를 획기적으로 개선한 형태가 하나의 지지체에 셀을 직렬로 연결함으로 전극의 선폭 및 단위 셀 간의 간격이 기존 평판형, 원통형에 비해 대폭 축소되어 전극 및 연결재의 저항손실을 최소화할 수 있는 Segmented형 SOFC이다. Segmented SOFC에 적용하기 위한 세라믹 다공성 지지체는 연료와 공기에서의 화학적 안정성, 셀의 구성소재와 반응이 없으며 열팽창계수가 유사해야하는 특성을 가져야하는데 그 중에서도 지지체로써 적절한 기계적 강도와 높은 가스투과도가 요구되어진다. 본 연구에서는 고온에서 안정한 Spinel의 MgAl2O4를 주성분으로 하는 다공성 지지체를 압출 성형하여 평관형으로 제조하였으며 활성탄을 기공형성제로 사용하여 연료의 공급이 원활하도록 약 30%의 기공율을 가지는 다공성 세라믹 지지체를 제조하였다. 제조된 세라믹 지지체에 연료극(NiO/YSZ), 전해질(TZ8Y), 공기극(LSM)을 코팅하여 실제 SOFC에 적용이 가능함을 확인하였다.

As the traditional style is treated as one of the important themes in fashion recently, how to apply the formative character in Korean and Japanese traditional dress to modern fashion is searched through actual analysis of photograph material, Both design formative elements were confirmed by clothing and fashion department majors through visual data so that 20 pieces of them were selected as final analysis object. Korean traditional dress form in modern fashion emphasizes curvaceousness as plane division. On the other hand, that of Japanese shows straight line, layered, belt, big look through up & down connection style. Color in Korean traditional dress prefers white and original color and modern fashion displays the natural beauty through harmony of similar colors ; that of Japanese based on natural color such as persimmon color cherishes natural beauty and implicit moderation showing harmony of various original color with brilliance and neutral color. While texture in Korean traditional dress was fine and exquisite, that of Japanese preferred coarse and tactile ones. In motif, Korea was natural and geometric but Japanese variously used complex and geometric ones. Likewise, the result suggests that the formative character in Korean and Japanese modern fashion affects the modern dress format as new aesthetic sense and takes on more complicated and subtle aspect in basic form, not just use so far.

The attempt of the contemporary society to overcome the environmental crisis is considered what the whole world is currently interested in. Since value of resources recycling has become emphasized even more, the field of design is, now, working hard to prove how much they are passionate about this eco-friendly design. Of all those activities that the field of design is involving in, a concept called 'upcycling' is receiving the greatest spotlight as a new trend. When it comes to upcycling, you should understand it as a both functional and aesthetic upgraded idea of conventional 'recycling' which would re-use waste resources. With this upcycling, you will have a chance to re-create an object of a new value, and it is a design concept which would consider environmental aspects but also social aspects. Since the year of 2000, the field of furniture design has been pursuing a new design trend which would intensively concern this upcycling concept. In the light of the present circumstances described on the above, this study conducts a case analysis on how upcycling of different materials is applied to furniture design since the year 2000. In doing so, the study improve understanding on furniture design as proposing new ways for you to look at the concerned design. Not only that, it also comes up with ideas and directions for new upcycling furniture design which could be demanded by the environmental industry.

인터넷이 널리 보급되면서 발달한 온라인상에서 사용자들이 서로 공유된 가상공간의 다른 사용자와 상호작용할 수 있는 다사용자온라인게임은 그 시나리오나 수용방식에 대한 변화 가능성에 관한 내용을 다루고 있을 뿐, 그래픽 인터페이스에 관한 연구는 전무한 실정이다. 본 연구에서는 인터넷이라는 매체적 특징을 이용하여 다사용자온라인게임 사용자간의 상호작용에 주목하였고, 그러한 상호작용 요소를 중점적으로 한 그래픽인터페이스 요소를 추출하여 내용분석을 시행하였다. 본 내용분석을 위하여 각종 관련 게임 사이트에서 160개 게임의 905개 스크린 샷을 수집하여 빈도분석과 교차분석을 시행한 결과를 종합하여 보면 다사용자온라인게임은 3D그래픽 기술의 발전으로 캐릭터와 배경 및 시점에 있어 실재감 있는 화면과 애니메이션을 통해 사용자들의 가상현실 체험을 높이고 있다. 이를 위해 실재감을 방해할 수 있는 다른 조작요소의 색은 상대적으로 어둡고 공간을 작게 차지하도록 하는 경향을 띠고 있는 것으로 보인다. 이를 위해 기존의 게임과는 다른 인터페이스 레이아웃이 발전되어 자리잡고 있으며 또한 비교적 성공을 거둔 것으로 파악되는 인기도가 높은 게임의 경우를 미루어 보아 게임의 소재와 배경은 모호하게 설정하여 현실세계와 다르면서도 어디엔가 존재할 수 있음직한 세계를 설정하여 재미와 실재감을 동시에 높이고 있는 것으로 보인다. 또한 이러한 인터페이스의 변화를 주도하는 요인으로는 문화적, 기술적, 디자인적 요인으로 나뉠 수 있으며 각 요인들에 의한 획기적 인터페이스의 등장은 다른 게임들에도 영향을 미치게 되어 결국 인터페이스 유형 자체를 변화시키는 것으로 분석되었다.

최근 고도성장에 발맞추어 건축물의 에너지 효율등급 인증제를 실시하면서 외단열시스템(EIFS) 외장재 사용이 늘어나고 있으며, 건물의 외관상의 디자인을 중시하게 됨으로써 다양한 소재의 외장재를 적용하고 있다. 그러나 건축물의 내부 또는 외부에서 발생된 화재가 외장재를 통해 건물 전체로 확산되는 이른바 동시다발성 화재가 많이 발생하고 있다. 2010년 부산해운대의 고층건물에서 외장재를 통해 연소 확산된 화재가 발생하면서 건축물의 외장재의 관한 규제가 절실해졌다. 현재 국내 건축법과 소방법에는 내화구조 및 내장재에 관한 기준은 있지만 외장재에 관한 기준은 마련되어 있지 않다. 이에 현재 건축물 외장재의 법제화를 하기 위해서 많은 연구와 실험이 진행 중에 있다. 이런 노력에 앞서 현재 상용되는 외장재의 종류를 살펴보고 국내 건축물에 적용된 외장재에 대해서 알아보는 것이 이번 연구의 목적이다.

The purposes of this study were to analyze the formative relationship between Surrealistic clothes and hat with the focus on the period from the 1990's to 2008 and to find out the development direction of next hat design. The method to analyze the relationship between clothes and hats was the formative analysis by Marian L. Davis and Marilyn R. Delong. Hat design of surrealism was cylindrical or tear drop in a shape according to the principle of $D{\acute{e}}paysement$ and Trompe l'oeil, and was similar with the Form of a jacket, a sleeve, or a skirt. In color, accent color coordination mainly appeared and sometimes contrast color coordination induced illusion effect. In material, a variety of materials were used according to the principle of $D{\acute{e}}paysement$ and Trompe l'oeil, and contrast was widely used like color. In Decoration, the decoration or pattern of clothes was intactly applied to hats. The results suggest that clothes and hat have an organic relationship, and a hat style is changed with formative elements of clothes.
