Recently Renku (Haikai no Renga) is getting popular as well as Haiku in Japan. It was built up by Basho Matsuo, who was the most famous Haiku poet. It is said that Kyoshi Takahama proposed the name of "Renku" to distinguish it from "Renga" and "Haiku" in 1904. Renku meetings are held like Haiku ones regularly now in each place, and in several universities, they conduct a class exercise of Renku continuously. It is very important for plural persons to work together cooperatively. Poetry, Tanka, Haiku and Renku are usually composed of only letters. It sometimes happens that we add pictures to make them more attractive and to aim at synergy by collaboration (letters and pictures). However, the study to produce 3DCG animations of Renku has not been reported very much. Sowe studied to produce 3DCG animations work based on the rule of Renku and its evaluation.

Agfa 8E75HD 사진건판에서 얻은 dichromated gelatin(DCG) 박막에 구면파와 평면파를 간섭시켜 holographic zone plate(HZP)를 만들었다. DCG박막의 비서형적인 광학특성들을 고려하여 HZP의 이론식을 유도하였다. 이 이론식에 의한 HZP의 초점거리를 거리는 f. f/2, f/3, f/4, ... 였으며, 실험적으로도 평면파를 입사하여 6개까지의 해당 초점들을 관측하였다. 칼날 주사 방법으로 측정한 첫 번째 재생 초점 근처에서의 빔의 모양은 Gaussian 분포를 가짐을 확인하였다.

This paper concerns the design and implementation of a Bandwidth Variable Digital Chirp Generator (DCG) for the radar altimeter. A double SRAM parallel structure is used to breakthrough the upper DCG bandwidth limited by the highest clock frequency of the digital chips. An experimental system working in the waveform storage method has been implemented. We show that the bandwidth changed according to the radar altimeter's requirement and the design released the stringent speed requirement of the chips fur making a variable wide bandwidth DCG.

The purpose of study is to investigate the correlation between the Lyapunov exponent (LE) and the displacement of the center of gravity (DCG) for clarifying walking stability on the treadmill. From fifteen young healthy subjects volunteered, lower extremity joint angles were recorded using a three-dimensional motion capture system with reflective markers. The anteroposterior DCG and the LE were calculated by a commercial software. A linear correlation between LE and DCG (p<0.05) showed that LEs compensated for walking distance on the treadmill walking. However, LEs were found to be independent of self-selected walking speeds by a negligible correlation between LE and the Froude number (p>0.05).

반사형 홀로그래픽 광학소자인 간섭필터를 제작하였다. 감광재료는 dichromated gelatin (DCG) 필름을 사용하였으며, 고성능의 간섭필터를 얻기 위하여 기존의 DCG 처리 방법을 수정하여 소개하였다. 제작된 간섭필터의 중심 파장에서의 최대 회절효율은 93%, 이때 대역폭은 17 nm 였다. 노출량에 따라 간섭필터의 중심파장과 대역폭의 변화를 측정하였으며, 이에 따른 DCG 필름의 특성을 분석하였다.

버즈풋 트레포일의 줄기에서 뿌리를 유도함에 있어, 최적의 유도조건을 확립하고자 배양토 종류별, 복합희토 처리 농도별, IBA 처리 농도별로 뿌리 유도율을 조사하였다. 원예농상토, 마사토, 강모래 등 3종류의 배양토에서 뿌리 유도율을 조사한 결과, 마사토(77.8%), 강모래(70.0%), 원예용 상토(41.1%) 순으로 높게 나타났다. 마사토와 강모래에서 복합희토 용액을 농도별로 처리하여 뿌리 유도율을 조사한 결과, 마사토에서는 복합희토 용액 60 ppm 처리에서 90.0%로 높게 나타났고, 강모래에서는 복합희토 용액 20 ppm 처리에서 80.0%로 높게 나타났다. 마사토와 강모래에서 IBA 용액을 농도별로 처리하여 뿌리 유도율을 조사한 결과, 마사토와 강모래를 사용한 두 처리 모두 40 ppm에서 뿌리 유도율이 96.7%로 동일하게 최고로 높게 나타났다. 이상의 결과로부터 포장에서 재배하고 있는 버즈풋 트레포일의 영양체증식을 하기 위해서는 버즈풋 트레포일 줄기를 절단하여 강모래나 마사토에 삽지 후 IBA 용액을 40 ppm 농도로 처리하여 30일 이상 배양하는 방법이 가장 효율적인 것으로 밝혀졌다.

홀로그래피 HUD의 제작에 필요한 주요 파라미터를 살펴보고 이들 값을 결정하기 위한 관계식을 유도하여 설계 값을 설정하였다. 기록 방법으로는 간섭무늬에 의한 잡음을 최소화할 수 있는 공기층 반사 기록방법을 제시하였다. 특히, DCG필름을 처리한 후에 생기는 중심파장의 이동을 보정하기 위한 새로운 방법을 소개하였다.

In this study, a novel education system for inspection of concrete bridges is presented. The new education approach uses virtual reality (VR) and three-dimensional computer graphics (3DCG) in training engineers to become bridge inspection specialists. The slow time-dependent deterioration of concrete bridges can be reproduced on the computer screen in any chosen time frame, thus providing the trainees with illustrative and educative insight into the deterioration problem. In the proposed VR/3DCG approach a three-dimensional model of concrete bridge, including surfaces, viewpoints and walkthrough paths is created. With the help of this virtual bridge model, an experienced bridge inspection specialist teaches the different deterioration phenomena of concrete bridges to the trainees. The new system was tested, and the inspection results from the case bridge showed that in comparison with the traditional Japanese bridge inspection education system, the new system gives better results. In addition to the improvement of quality of bridge inspections, the new VR/3DCG system-based education brings along some other, more intangible benefits.

Purpose - This study's purpose is to examine the effects of the country-of-origin antecedents on overall attitudes and the impact of overall attitudes on satisfaction and loyalty. Research design, data, and methodology - This study provides useful insights into international female purchasing behavior in the cosmetic industry in South Korea. This study explores the elements of country-of-origin antecedents, (cultural interest, perception of brand image, perception of fashion, perception of product quality, perception of price, and perception of advertising), on overall attitudes as well as the effect of overall attitudes on satisfaction and loyalty. Results - The results show that the effects of such antecedents are significant. Additionally, the effect of overall attitudes on satisfaction and of satisfaction on loyalty were significant. Conclusions - The findings of this study provide some important practical implications. First, with customer brand awareness growing along with products standards, considering the concepts points of parities and points of differences, the Korean cosmetic industry should try to establish brand associations with natural organic ingredients in its cosmetic items, distinguishing them from the majority of non-Korean brands.
