In this study, an accelerated aging experiment for fabric and paper was conducted using two light emitting diode(LED) sources with different wavelength characteristics, and the discoloration under each lighting type was examined. Hanji(Korean traditional paper) and related textiles showed more discoloration under blue LEDs, while the blue wool standard showed more discoloration under white LEDs. This, indicated that the deterioration varied depending on the sample color. The the effect of the light source on artifact deterioration was primarily related to the total radiation flux(expressed in mill watts), rather than the total luminous flux(expressed in lumens). In addition, the discoloration of the investigated artifacts was dependent on the color rendering of the lighting.

Six entomopathogenic fungus isolates, Beauveria bassiana J57A, Nomuraea rileyi J125A, Paecilomyces farinosus J3A, Paecilomyces fumosoroseus J50A, Metarhizium anisopliae J88, Aspergilius sp. J64A, causing muscardine disease and aspergillosis in the silkworm, Bombyx mori were investigated for their cultural and morphological characteristics (on PDA culture media within 14 days at $24^{\circ}C$). The results showed that they differ each other from the features of cultural characteristics (colony elevation, colony color, colony growth rate) or morphological characteristics (conidiogenous cell structure, phialides, conidia size and shape). Among cultural characteristics, colony color is the easiest recognizable character between isolates. The morphological characteristics of each fungal isolate correspond to the descriptions of current system of classification.

To investigate the deterioration of textiles with metal thread, I surveyed 40 textile objects, dating from the 11th to the 19th century from Korea, China, Japan, and Central Asia at the Metropolitan Museum of Art, New York. This survey included various types, widths, and thicknesses of metal thread. In addition, deterioration was examined under the microscope and color information was collected using the spectrophotometer. While investigating metal thread in the collections, I fabricated 12 different types of metal samples with metal leaf(24K gold, silver, and copper leaf), adhesive (hide animal glue and a mixture of hide animal glue and iron oxide red), and paper substrate(Korean mulberry and Taiwanese kozo paper). The accelerated deterioration process of those fabricated samples was carried out using a light box(UV and daylight), and a humidity cabinet. In the light experiment with blue scales textile fading card(aka, blue wool standard), the metal leaf began to peel off during the deterioration process with 756,000 lux-hours UV and daylight. In the temperature and humidity experiment, I could observe the reddish tarnish on copper, and some part of it began to peel off. Color reading on the light exposed samples showed that the degree of color change on the surface follows the amount of exposure as it increased over time. On the other hand, color change on the samples after artificial deterioration using temperature and humidity factors showed random change of color with occasional spikes. Distortion of original shape worsened in the samples exposed to temperature and humidity.

The color gray in the cinema expresses the private or public memory and oblivion in the reminiscence scenes. The aesthetic function and meaning of gray that interacts with other elements in cinematic time and space are expanded in various ways. This study was analyzed the cases in which gray was used as the main visual style by limiting the scope to Korean films. Based on the traditional cultural symbolic meaning of gray, I analyzed how it was applied and transformed in films, and interpreted the cultural-social meaning by the interaction between gray and other elements. In film history starting from monochrome, gray has been used as a visual device suitable for realizing cinematic or imaginary reality. Gray is adopted when dreams or recollections are visualized as imaginary reality, and it is used when dreamy imaginations of daydreaming are demonstrated. Gray, which reproduces the dreamlike reality of imagination, is the concrete and realistic way of expression. First, in Korean films, gray is a flashback visual device that recalls the past, and is an intermediary visual form that materializes the imaginary. In films such as Ode to My Father (2014), DongJu (2015), A Resistance(2019) and The Battle : Roar to Victory (2019), the gray of the past is a visual device for cultural memory that builds the homogeneity and identity of the group. In the era of hyper-visibility, gray in black and white images is intended to be clearly remembered by unfamiliarity rather than blurry oblivion by familiarity. Second, in genre films with disaster materials such as Train To Busan (2016) and Ashfall (2019), the grays of rain, fog, clouds, shadows and smoke highlight other elements, and the gray color causes anxiety and fear. In war films such as TaeGukGi: Brotherhood Of War (2003) and The Front Line (2011), gray shows a more intense brutality than the primary color. In sports films such as 4th Place (2015), Take Off (2009) and Forever The Moment (2007), gray expresses uncertainty and immaturity. Third, gray visualizes the historical memory of A Petal (1996), the oblivion in Oh! My Gran (2020) and Poetry (2010), and the reality of daydreaming Gagman (1988) and Dream (1990). At the boundary between imagination and reality, gray is a visual form of dreams, memories and forgetfulness.

Living in the present, specially in this multi-cultural society, we have to look back our tradition in many aspects. And we try to find out our own identity. Color is very important element to decide what is traditional or not. And it‘s a prominent factor for design subject visually. With the color from traditional residence, we will figure out traditional color and it‘s combination which the people prefer today, so we can applicate and develop it in the present design. Using color palette which has extracted from traditional building and space, a survey has done of university students for finding out which they think of traditional color. The result showed that Y-R type and Y-R type in color palette was the most traditional things by the students. This study is meaningful in the way of clarifying that university students think what is the traditional color and color palette.

Felt, is one of the Korean traditional woolen fabrics, that is thermally excellent and durable, so it has been widely used for various living goods from the ancient time to the modern society. Felt makes various changes in colors and shapes, does not change easily even after a long-term use, and is easy to clean. In this study, the origin and history of felt were researched. Also, different kinds and shapes of felt and the currently used manufacturing technique, and how the Korean traditional pattern-applied cultural products were developed using felt were examined as well. The method of this study were as follows. First, felt manufacturing techniques used after investigating the precedent studies, books, records and literatures of museums, the existing relics of felt were examined. Second, the conditions of the traditional pattern-applied cultural products were found out through the precedent studies after examination of kinds and symbols of the Korean traditional patterns. Third, patterns that were applied to cultural products were selected and designed with new patterns. Fourth, the past techniques were conducted with the following three methods by referring to the range of cultural products manufacturing; )color felt made with one color, pattern felt, and pattern-embroidered felt. Fifth, the following products combined with decoration and practical application by applying felt techniques were used. This study was aiming at the development of practical cultural products made with the traditional wool, felt, which can receive a good response from all age groups. It is allegedly required to develop various cultural products through studies and the rediscovery of the national traditional materials. In the future, it is necessary to study in such a way that diversification and differentiation are made through approaches and attempts with various techniques.

War films are a general term for films that have battlefields as their main background. Although war films as a genre directly deal with combat situations, they also deal with characters or subjects related to war. War films promote patriotism and nationalism, but they also argue against war by highlighting the disastrous war. This study is based on the color theory that the meaning of film color is temporarily and infinitely generated according to the cultural differences, with Eisenstein's creative theory on film color and pathos. I wanted to clarify the pathos effect and the meaning of color green expressed in the Korean war films. In war films, colors are visualized in art forms such as symbols, similes and metaphors. In war films, color green symbolizes life. On the battlefield, the green of nature stands against the catastrophic situation. The green of ecology, which insists on the flow of life, evokes fear in ecological crises such as war, disaster and climate change. The dark green caused by a catastrophe like war warns of the destruction of life. The connotation of color is temporarily and infinitely expands according to the cultural differences. The dark green, which visualizes the battlefield of destruction, is a form and element of pathos that indicates changes in emotions such as sadness, pity, grief and despair. Pathos as an emotional appeal is a leap from the quality to the quality of the means of expression and refers to the departure from Dasein. The green color that dominates the visuals of war films is a symbol of life and functions as a pathos that makes emotional changes take a new leap. A qualitative leap through pathos means all changes that become new.
