In this paper, affection of jumping motion factors on visual effects are studied for game character's natural motion realization. First, 3 kinds of games that realize natural motions are selected and 4-types of characters jumping motions are captured from it. Then, the motions are measured using four fundamental principles of jumping as takeoff strength, landing impact, landing elasticity and flexibility, and measured in motion factors as time, distance, angle either. Finally, consistent characteristics of visual effects and motion factors on jumping motion are suggested. The study could be used to basic information for realization of character's natural jumping motion.

The objective of this study is to investigate material properties and quality control of cast-in-place high strength concrete. High strength concrete with a design strength of 420 kgf/$\textrm{cm}^2$ is successfully produced at a ready-mixed concrete plant, and placed at a tall building. Many laboratory and field tests are carried out for the successful construction of the reinforced high strength concrete building. As the results of this study, the average actual 28-day compressive strength is 513 kgf/$\textrm{cm}^2$ and the coefficient of variation is 6.8%. The placing speed is comparable to normal strength concrete, however, the pump pressure is higher than that of normal strength concrete. To prevent cracks of massive and long concrete members, the control of hydration heat and shrinkage is very important.

The purpose of this study is to analyze the expressive effects of Queen Elizabeth I's robes in cinema and also to present two examples of Queen Elizabeth I's robes designed and made based on these expressive effects. To this end, this study wilt first examine Queen Elizabeth I's robes in her portraits according to the visual definers and emblematic meanings. Then on the basis of these knowledges, analyze visual definers and viewing priorities of Queen Elizabeth I's robes in five movies. Thereinafter, these robes will be classified based upon Belong(1998)'s four expressive effects. excitement. calmness, strength and delicacy. Finally, this study will demonstrate calmness and delicacy among four expressive effects through two robes made for the purpose. After analyzing the expressive effects of robes in five Queen Elizabeth I's movies, one can conclude excitement. calmness, strength, and delicacy can be found according to the flow of the story. Since this analysis focuses mainly on one particular person during one Particular period of time, there was a fundamental silhouette prevalent among the Queen's robes which then can be classified into different forms. Moreover, Queen's character in itself embodies authority and grace which. in turn, facilitates the presentation of the four expressive effects along the story line. In conclusion, thorough historical research on the character and the period. in addition to analysis of the visual definer and viewing priorities, is imperative when designing a historical costume.

The purpose of this study was to increase uv-cut ability of cotton, ramie, and rayon fabrics dyed with safflower red colorants. For this purpose, samples treated with uv-cut agent and tannic acid were compared with the untreated samples after ultraviolet(uv)-light exposure in terms of K/S value, color changes(${\Delta}E$), SEM, and tensile strength retention. K/S value rapidly decreased with increasing exposure time, but K/S value of the samples treated with both uv-cut agent and tannic acid decreased less than that of untreated samples. As increasing exposure time, $L^*$ and $b^*$ increased, $a^*$ decreased, and so ${\Delta}E$ increased, indicating less red character and more yellow character in color. This leads to change hue, value and chroma value. But color change of samples treated with both uv-cut agent and tannic acid was less than that of untreated samples. SEM pictures showed a severe degradation by uv exposure in all samples. Tensile strength slowly decreased for 21 days. And after this point, the decreased proceeded more rapidly. Tensile strength retention of the samples treated with uv-cut agent and tannic acid was higher than that of untreated samples.

Similar to the other cultural contents, the character industry is based on the media which acts as the technological background. In fact, the character industry is the process of that a created character accesses to the consumers via media, builds its value and becomes licensed as a brand in the market. Therefore, it is crucial to select the most effective media for the consistence of a character in the market, as well as for construction of a higher brand quality of the character. Today, "Webtoon" might be considered as one of the marketing means which utilizes the Internet media for raising the character as a brand. Webtoon has apparent strength because it can be produced in shorter period and with less expense than through other media. Furthermore, Webtoon can be simply featured by the easiness of two-way communication and transference to another media through it. For these reasons, and according to the result of analyzing some Korean Webtoons, it seems obvious that the most effective media in character marketing is the Internet. In addition to the Internet, the strategic development in the media-mix is also important for establishing a brand of a character. However, the effective media-mix is available only when the character's external identity meets with the trait of its media. For the purpose of learning how the media-mix works when a character reaches for the consumers, a character "Hamataeng" was born and used in the experiment. This study will explain the marketing process through the use of own-created Webtoon and other contents, and suggest the ways to build a brand of a character. In addition, it is also indicated that a media-mixing strategy for transformation and expansion of the character to other media.

The objective of this study is to investigate the characteristics of natural indigo dyeing of cotton fabric. Reduction and dyeing were carried out by one-step process using an infrared dyeing machine at the liquor ratio of 1:100, and subsequently oxidation and washing in water were followed. Dye uptake was increased with the increase of indigo concentration. Over the full range of dyeing tests, the dyeing condition was optimized to $40^{\circ}C$ for 40min. For most of dye concentrations, the cotton fabrics showed mainly PB color. Maximum K/S value was shown at 4g/L of sodium hydrosulfite concentration and the color strength increased with the increase of dye concentration. Value(lightness) decreased with the increase of dye uptake irrespective of mercerization or reduction method, while the mercerized cotton showed two times higher dye uptake than the untreated cotton. Whereas hue of the untreated cotton showed large decrease of P character(5.6~3.5 PB) with the increase of dye uptake, that of the mercerized cotton increased P character(4.7~5.5 PB). Irrespective of mercerization, value and chroma decreased with the increased of dye uptake. In addition, the untreated showed lower chroma than the mercerized cotton. In the case of traditional reduction, hue of the untreated cotton was changed very little with the increase of dye uptake. For hydrosulfite reduction, P character decreased with the increase of dye uptake. The difference of hue value was small with the change of reduction method(hydrosulfite reduction or traditional fermentation). Color character was not influenced by the changed maximum absorption wavelength. Washing fastness showed 4~4/5 shade change rating without any staining. And dry rubbing fastness was good at low color strength. The bacterial reduction ratios of dyed cotton fabric were also increased.

Cold weather concrete presents the many characteristic variation of quality, according to the mixing and cooling point, the cooling time and the quantity of air besides the compressive strength of concrete. Thus, in this study to verify the character of cold-weather concrete we make the concrete specimens at laboratory and cool them at cooling-melting machine and then test the 7days compressive strength of them, with the variation of compressive strength of concrete, cooling point, cooling time, cooling weather and air quantity. At the results, the compressive strength of concrete decrease in the case of early cooling point, long cooling time, low cooling temperature and the low design compressive strength
