Korea has been designated as a National Intangible Cultural Heritage with outstanding value among intangible cultural heritage. We have supported various exhibitions and performance activities, and the Intangible Cultural Heritage Public Events. However, in recent years, more diverse policies have been pursued in order to revitalize transmission activities and the State is leading the Completion examination system. In order to improve the utilization of crafts, we introduced a Craft Bank System. In addition, to increase the marketability of crafts, we have implemented the certification system for crafts. For the diversity of transmission activities, we are promoting the Transmission Education School System. In order to fuse traditional activities, the Intangible Cultural Heritage Exhibition is being held and the World Heritage Forum is being pursued. In this study, we analyze various policies of the new intangible cultural heritage and investigate the problems and seek ways to improve them.

Stone in the Cho Sun Dynasty has been used as the material of industry arts, widely building materials and an important material for the artistic design. But it has been generally used as an use of practical living Product like, suban, a metal printing type, a fire place, a pillowcase, a pencil case, etc, and ornament with the quality of stone material and the aesthetic view. There are several problems as like size, quantity, delivery and processing method with the stne material according to its variety and selection. Accordingly it has been studied through the whole process of shape, a material selection of design and processing method as well as studying about small stone crafts which were manufactured in the Cho Sun Dynasty, considering these problems. Stone crafts in Cho Sun Dynasty has been widely used as a living tool. There was some what difference on manufacturing purpose on its technique of folk crafts of stone crafts, but, through the research of collected crafts, they were almost the same that social need, user's taste and hobby in those days were reflected in. In the result of analysis as dividing the stone crafts into daily living product, stationery and tool, the major of daily products have been manufactured with emphasis of practicability. And they have been manufactured from agalmatolite for the propose of use. further, kitchen product had no design due to the function and living products which has been used in the main living room has been carved with the decorative expression of the various form by using intaglic, relieve, inlaid technique, etc. For the stationery, it has been characterized with aesthetic point considering the decorative effects & selection of material in accordance with use. A material for manufacturing has been used in the range of agalmtolite, atopaz, a sapphire, white stone etc. As the result of this research, It was noticeable that there was the spleudidness on the expression of design and carving. It was also noticeable that black stone and guanite have been widely esed because it didn't need the delicacy as a tool.

The Korea navy has a vital national interest in maritime security. The national strategy for maritime security focuses on preventing terrorism, crime, and hostile acts in the maritime domain. This requires the development of high speed crafts for maritime security in the South Korea domain. This paper reviews the state of the art on the development of high speed craft internationally, including efforts by the U.S. navy, and analyses the riverine environment to operate high speed crafts in South Korea. This paper makes specific proposals for high speed craft such as their main dimensions, speed, endurance, hull structure material, propulsion system, and general arrangement and 3D shape. This paper was used in the generation of basic resources for future ROC (requirement of capability) of high speed crafts using an engineering methodology.

Between 1890-1914, the fundamental changes of the housing in United Sates of America were provoked to attempt the housing developments to adapt modern social system. The worthy of notice is that F L. Wright's Prairie House had been tested and built during the period as 'the first and second era' Despite the transition period in America, this represents that Wright's Prairie House series were developed. There are possibilities that some of the reformers assertion for Housing Development, on behalf of Arts & Crafts Movement, led to Wright's early house inner space design. For this reason, this study is to examine Ideologies that Wright has been accepted between the turning point of America's Arts & Crafts Movement and Hull House Circle. In terms of the ideologies acceptance, the study is also to examine how to be represented his inner space design characteristics. As the result, between'Simplification'housing development and the traditional housing In America, F L. Wright sublimated his own architectural aesthetic as accepting all functional elements to consider inevitability in this period, such as the association between economical and rational space, the plan to led on free plane, the spatial side and the stability of family life and the community, through the unification space having the consecutiveness.

High-speed crafts suffer from losing a huge amount of their machinery energy in the form of heat loss with the exhaust gases. This will surely increase the annual operating cost of this type of ships and an adverse effect on the environment. This paper introduces a suggestion that may contribute to overcoming such problems. It presents the possibility of reusing the energy lost by the ships' exhaust gases as heating source for an absorption air condition unit onboard high-speed crafts. As a numerical example; the proposed method was investigated at a high-speed craft operating in Red Sea between Egypt and the Kingdom of Saudi Arabia. The results obtained are very satisfactory. It showed the possibility of providing the required ship's air condition cooling load during sailing and in port. Economically, this will reduce the annual ship's operating cost. Moreover, it will achieve a valuable reduction of ship's emissions.

The planing craft is designed specifically to achieve comparatively high speed on the surface of the water. Most of planing crafts have installed the spray strip in decreasing of wave impaction and improving motion performance of rolling and pitching et al. It is known to reduce the spray and frictional resistance by the effect of lift and improvement of wave profile in high speed. In this paper, the high speed planing crafts with & without spray strip in bottom were performed to compare the resistance performance by model-test. In conclusion, the high speed planing crafts with spray strip in bottom was proved to effect of the resistance decrement of $3.0{\sim}5.0%$.

This paper examines William and Ellen Craft's Running a Thousand Miles for Freedom (1860)-a narrative of the enslaved couple's escape from Macon to Philadelphia in the guise of a white male master and a colored slave. Expanding Judith Adler's notion of "travel as performed art," my reading of Running focuses on the Crafts' stratagems of transvestism-crossing boundaries not only of gender, but also of race, class, and disability. If travel can be understood as a form of performed art, then why not address a traveler as a performance artist? I present William and Ellen's role-playing in Running as performers of crossing borders and categories, or, as "fugitive performers," since the couple's story never reaches its final arrival but narrates an eternal run-away, far more than "a thousand miles to freedom." Using social stereotypes of race and gender to disguise, William and Ellen plot, write, choreograph, play, and recite on the moving stages and manipulate the others-especially white American audiences-who accompany the couple's run-away and those who were responsible for the cultural drama-a tragedy of American slavery. Becoming "fugitive performers," William and Ellen de-essentialize and debunk the nineteenth-century America's firm belief in distinct color line between black and white, and in the high yet unstable bars between male / female, abled / disabled, master / slave, and freedom / slavery. The Crafts alert their contemporaries and readers by presenting the complex and permeable boundaries of race, gender, class, social and cultural ability.

The free and forced nonlinear dynamic behaviors of Porous Functionally Graded Material (PFGM) plates are examined by means of a High-Order Implicit Algorithm (HOIA). The formulation is developed using the Third-order Shear Deformation Theory (TSDT). Unlike previous works, the formulation is written without resorting to any homogenization technique neither rule of mixture nor considering FGM as a laminated composite, and the distribution of the porosity is assumed to be gradually variable through the thickness of the PFGM plates. Using the Hamilton principle, we establish the governing equations of motion. The Finite Element Method (FEM) is used to compute approximations of the resulting equations; FEM is adopted using a four-node quadrilateral finite element with seven Degrees Of Freedom (DOF) per node. Nonlinear equations are solved by a HOIA. The accuracy and the performance of the proposed approach are verified by presenting comparisons with literature results for vibration natural frequencies and dynamic response of PFGM plates under external loading. The influences of porosity volume fraction, porosity distribution, slenderness ratio and other parameters on the vibrations of PFGM plate are explored. The results demonstrate the significant impact of different physical and geometrical parameters on the vibration behavior of the PFGM plate.

In this study, the natural frequencies of Functional Graded Materials (FGM) plates are predicted using Artificial Neural Network (ANN). A model based on Third-order Shear Deformation Theory (TSDT) and FEM is used to train the ANN model. Different training methods are tested to simulate input and output dependency. As this is a parametric model, several architectures and optimization algorithms were tested. The proposed model allows us to minimize the CPU time to evaluate candidate material properties for FGM plate material selection and demonstrate their influence on dynamic behavior. Consequently, the time required for the FGM design process (candidate materials for material selection) and the geometric optimization of the FGM structure would remain reasonable. The ANN model can help industries to produce FGM plates with good mechanical properties of the selected materials. I addition, this model can be used to directly predict vibration behavior by testing a large number of FGM plates, representing all possible combinations of metals and ceramics in today's industry, without having to solve any eigenvalue problems.

This study examines the process of Korea's acceptance of the concept of Art Craft through research on ancient remains and relices (朝鮮古蹟調査) and a series of projects undertaken by the Japanese Government-General of Korea, and the traditions and canons of craft established in the process. Crafts defined in law referred to fine and exquisite techniques for creating antiques, or genres of art such as painting or sculpture. The Yi Royal Family Museum and the Museum of the Japanese Government-General of Korea spearheaded the popularization of the term "Mi-sul-gong-ye (Art Craft, 美術工藝)." The artworks displayed in these two museums visually embodied past traditions. In general, the term "craft" was frequently used to refer to ancient art, and crafts specifically became traditions to be protected and conserved by designation as legal treasures for display in museums. The establishment of traditions and canons of craft exerted a great influence on crafts produced during this era. The cultural policies and imperial tastes of Japan played a crucial role in this process. In previous research, scholars divided the concept of craft in the modern era into two categories: industrial craft and art craft. However the so-called "art craft" is not a homogeneous category. It includes both ancient art (antiques) and the pieces made in modern age. Ancient art became canonized and the basis of contemporary production. Moreover, features of contemporary craft were diverse. By subdividing concepts of art and crafts, which have hitherto been discussed collectively, this study will serve as groundwork for accurately understanding "invented traditions" and features of modern craft.
