본 논문은 게임 캐릭터의 자연스러운 점프 동작을 위해 점프 동작요인들이 시각적 효과에 미치는 영향을 분석하였다. 우선, 자연스러운 점프동작을 보여주는 상용 게임 3개를 선정하고 각 게임에서 4가지 체형별 캐릭터 점프 영상을 추출하였다. 이것을 점프동작의 4가지 주요 원칙인, 도약시의 힘, 착지시의 충격, 착지시의 탄력성과 동작의 유연성으로 평가하였다. 그리고 점프 동작별로 시간, 거리, 각도 요인으로 측정하였다. 최종적으로, 게임 캐릭터의 시각적 효과와 동작 요인들과의 일관된 특징을 분석하여 제시하였다. 본 연구는 자연스러운 캐릭터 점프 동작 구현을 위한 기초 자료로 활용이 될 수 있을 것이다.

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.

캐릭터 산업은 여타의 문화콘텐츠 산업과 같이 창작된 콘텐츠와 더불어 미디어라는 기술적 환경을 토대로 한다. 즉, 창작 캐릭터가 미디어를 통해 수용2자에게 도달되고 이를 기반으로 시장에서 형성된 캐릭터의 브랜드 가치를 바탕으로 라이선싱을 통해 이루어지는 산업이라 할 수 있다. 캐릭터의 생명력을 연장시키고 브랜드로서의 가치를 높이기 위해서는 효율적인 미디어의 선택과 활용이 필요하다. 웹툰 역시 웹툰 캐릭터가 브랜드로서 발전하기 위해 인터넷 미디어를 활용한 마케팅 수단 중 하나로 볼 수 있다. 또한 타 미디어에 비해 짧은 기간에 적은 비용으로 제작하여 시간, 장소에 구애 받지 않고 콘텐츠의 전달이 가능하다. 그리고 쌍방향 소통, 미디어 확산이 용이한 디자인적 형태와 매체적 특성을 가지고 있다. 국내 웹툰 캐릭터의 사례를 분석한 결과, 인터넷 미디어를 중심으로 한 캐릭터 마케팅이 가장 효율적이었다. 또 캐릭터 브랜드화를 위해서는 전략적인 미디어믹스 전개가 필요한 것으로 나타났다. 아울러 웹툰 캐릭터의 외형적, 매체적 특성이 일관된 아이덴티티를 유지해야 효과적인 미디어믹스가 가능하다. 캐릭터가 수용자에게 도달되는 과정에서 미디어믹스가 실질적으로 어떤 작용을 하는지 알기 위해 캐릭터 '하마탱'을 개발하였다. 더불어 자체 제작한 웹툰과 기타 콘텐츠를 활용한 마케팅 과정과 캐릭터 브랜드 구축방안, 그리고 타 미디어로의 변경과 확장을 위한 미디어믹스 전략을 제시하였다.

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
