Animal glue is a traditional material that was used widely as an adhesive in cultural artifacts, such as Buddhist paintings, dancheong (traditional multicolored paintwork on wooden buildings), mother-of-pearl inlay, and so on. Spectroscopic methods, such as infrared spectroscopy, have been used for the analysis of animal glue. However, such methods do not yield sufficient information about the constituents of the glue. Because pyrolysis/GC/MS analysis is able to estimate the components of a material through the examination of its pyrolyzed products, it is useful for the analysis of polymeric material. In this study, pyrolysis/GC/MS analysis was used to determine the chemical composition of animal glue. The appropriate conditions for analyzing animal glue were established by examining pyrolysis temperature, quantity of the sample, and the repeatability of the method. Some products of pyrolysis were identified. We also analyzed commercial gelatin and animal glue using the established method and found almost no differences in chromatograms among the samples. The results will be used as supporting data to confirm the use of animal glue in cultural artifacts and to replace traditional animal glue by commercial gelatin.

This study examines functions in traditional Korean special costumes in accordance with the climatic factors of the Korean peninsula. The study focused on clothes worn by commoners during the Joseon dynasty. Climate change has been a major global issue in recent times, and it has been a hot topic in social, cultural, scientific, economic, and industrial communities. Studies have been conducted regarding the rapidly changing climate, and finding ways to cope with unusual temperatures. This thesis studies the development of special costumes in preparation for unusual climates, and requirements of the costume in accordance with the climatic factors, as well as the direction of its development. Its biggest significance lies in collecting and organizing the research data on special costume studies, and on costumes of the commoners, which have been fairly insufficient up to this point. After the Little Ice Age, the Joseon Dynasty period faced poor external environment due to unusual temperatures. The results of studying the costumes of the commoners are as follows: The climate of the Korean peninsula displayed different characteristics depending on the season, so the form, material, and appearance of the seasonal clothing items showed clear differences, and the difference in the crops cultivated according to the climate led to difference in material and material preference shown in the costumes. This meant that costumes differed based on region. In addition, difference in social hierarchy, regulations on costume according to class, and farming oriented social background during the period of Joseon dynasty slowed the development of costumes of commoners, but appears to have had a positive effect on the development of special costumes. We anticipate more succeeding studies on costumes of the commoners and special costumes in the future. We hope more costumes that can wisely respond to the approaching changes in temperature in the Korean peninsula can be designed via modernization of traditional Korean special costumes.

The purpose of this study was to closely examine the history of glasses and their cases used in the middle and late of Joseon Dynasty and identify inherent quality of our traditional glasses cases through color analyses of glasses cases' material and shape. While theoretical examination was conducted based on the literatures of glasses and their cases that firstly appeared in around Japanese Invasion (Imjin war) of Korea in 1592, practical analyses were demonstrated on photos of glasses cases used in the middle and late of Joseon Dynasty collected from both museum pieces and the internet which were grouped into wood, fabric, paper, sharkskin, hawksbill and cow's horn in accordance with their materials. 623 color samples were abstracted from collected 159 glasses cases and quantity analyses on each material were performed respectively. Abstracted representative colors based on the result of color analyses were classified into the main materials and accessories' color scheme. The result of this study are as follow: firstly, both Yellow and Yellow Red were mostly used in main materials. In Fabric case's colors were widely used in embroidery and in animal matter material cases such as sharkskin, hawksbill and cow's horn, which can be used as itself or dyed, Green Yellow shown in high frequency. Secondly, accessories were analyzed into similarity coloration with main materials. From this finding, it turns out that our traditional cases have characteristic of similarity coloration between main materials and accessories. Red Purple and Purple Blue in high frequency in accessories used as an accent color. Finally, based on the analysis of hue and tone, while the middle and low value colors shown in very high frequency, the high-chroma colors hardly shown.

The objective of this study is to find out the recent trends of hanok design based on 58 hanoks appeared in architecture magazines in the last 10 years. The cases are analyzed in terms of location, size, building form, spatial organization, material, roof form, and the ceiling form of living room. The consequences of this study is as follows; Most of the recent hanoks are built in rural area (91.4%), which shows the hanok is not accepted as an urban house type. Hanoks tend to be built in 2 stories whose 2nd floor is smaller than the 1st floor. (34.5%) The preferred size is total floor area of $99.2{\sim}165.2m^2$ (62.0%), 3 rooms (46.6%) with a traditional ondol room (60.3%). The buildings with ㄱ-shape (43.1%) and linear-shape (27.6%) are preferred, and the compact plan type similar with apartment house appears (13.8%). In the roof design that greatly influences the appearance of building, the traditional design factors such as half-hipped roof (55.2%), double eaves (27.6%), and eaves curve tend to be sustained. In terms of spatial organization, most of recent hanoks have double-layed plan (74.2%). The living room mostly has separately defined space. (82.8%) The indoor and outdoor tend to be connected by a narrow wooden veranda (39.7%), while some cases don't have any wooden floor space (48.3%). The entrance is adopted as an important spatial element in front part of building (75.9%), and it influences the appearance of building. The living room, the counterpart of the wooden floor hall in traditional hanok, and kitchen tend to be interiorized. In terms of material, the cement roof tile and red clay brick are preferred. Consequently, the walls of recent hanoks have the image of brick structure rather than the wooden frame structure of traditonal hanok.

This study examines the types and forms of underwear worn during the Joseon Dynasty period, and the purpose of this study is to apply the Joseon underwear design elements into designs of modern clothes, and make clothes that have practical use. In addition, it examines natural dyeing in the production of works, using a dye that contains tannin to increase color fastness. This study, first, looked into the types of female underwear during the late-Joseon Dynasty period through literature research and literature study. Second, the study chose artificial silk material (rayon), which was applied with dye containing tannin, and then with indigo (Jjok) and a different dye. Also, the study tested color fastness by washing the material, and rubbing fastness was tested if the material was either dyed with indigo. if it was dyed first with dye stuff containing tannin, and then with indigo dyeing color. Third, using the underwear types in the Joseon Dynasty period, the study developed and produced a dress, a skirt and pants that could be worn in modern life on a daily basis by applying Mujigi-chima (underwearskirt), Dan-sokgot (slip), Salchang-gojaengi (loosedrawers) and Sok-baji (bloomers) forms. Dresses applying underwear skirt using naturally-dyed artificial silk, dresses applying Salchang-gojaengi, dresses applying Dan-sokgot, skirt without a crotch designed in the form of pant swith an open crotch, and pant skirt with a crotch-applying pants with an open crotch were produced. In the future, hopefully, various studies of collaborations of Korean traditional clothing, and natural dyeing will continue to kee) the tradition alive.

This study was investigated the effect of the morphology change of copper (Cu) powders under the different rotational speed and milling time by using three kinds of grinding media with different size and materials, and performed DEM simulations of ball behavior. In order to clarify the mechanism of grinding by three - dimensional simulations of the ball behavior in a traditional ball mill, the force, kinetic energy, and medium velocity of the grinding media were calculated. In the simulation, the amount of change of the input energy was also calculated by adjusting the rotational speed, ball material, kinetic velocity, and friction coefficient in the same as the actual experimental conditions. The scanning electron microscope results show that the particle morphology changes from irregular to spherical when the ball size is small.

The background of historical Jing-Ju is a history, but the history Chinese wants to watch on the stage is the history dramatized by talented actors/actresses, not the history they want to learn. This thesis intends to examine traditional repertories whose background is historical people or accidents, among the lots of Jing-Ju repertories by each period, grasp periods, accidents, people, etc. preferred by Chinese and examine how they were dramatized. The general characteristics of historical Jing-Ju, grasped by each period, are as follows. The first, for the reason that there are lots of historical Jing-Ju in opera repertories, it can be mentioned by Chinese descriptive tradition and historical tradition. As lots of Chinese novels and drama works were written by history, basic models are suggested and clear development is shown, so there is an aspect which is advantageous for dramatization. Also, there are lots of works whose material is history for not only opera but also drama, TV drama because of the characteristics of China where historical books such as "史記", "戰國策", etc. The second, the period which is the background of historical Jing-Ju focuses on 漢 period, 三國 period, 隋唐 period, 宋 period and 明 period. It seems to be reflected by Chinese superiority to some degree if considering Jing-Ju was extremely popular during the 民國 period. The third, there are many characters who have patriotism loyalty among the historical Jing-Ju. It seems to be the result of discovering lots of materials for appealing patriotism in the situation they were dominated by Japan and the West during the 民國 period. The forth, the most single material is "三國志" among the historical Jing-Ju. This material has the factors of traditional idea, loyalty, fidelity, etc, but there are the most interesting characters and they were popularized by novels, etc. The fifth, in the historical Jing-Ju, the contents and character forms can be sometimes changed by character's skill because character's artistic achievement can play a great role for the completion of Jing-Ju.
