쌀을 실온에서 30분간 침지하고 가수량을 달리하여 취반하고 쌀밥의 관능적성질을 맛, 냄새, 겉모양 및 택스쳐로 나누어 각각 성질 묘사를 3가지씩 하였을 때, 찹쌀밥이 전반적인 관능적 성질에서 가장 높은 강도를 보였다. 멥쌀밥에서는 일반계 품종인 아끼바레쌀밥이 택스쳐 및 외관에서 다수계 품종(밀양23호 및 밀양30호)의 쌀밥보다 높은 강도를 보였다. 취반시 물의 첨가비욜의 증가는 전반적인 관능적 성질에 현저한 영향을 주었으며, 밀양30호 쌀밥의 경우가 가수량에 따라 관능적 성질의 변화가 가장 심하였다.

In this paper, forced vibration was used to regulate the droplet migration, fully recording the transient migration of droplets on a micro-textured substrate under the resonance frequency by a high-speed camera. The influence of resonance frequency and dynamic migration characteristics of droplets on the solid micro-texture surface under lateral vibration were researched. The experiment demonstrates that the driving force is caused by the difference between the left and right contact angles made the droplet oscillate and migrate, and as time t increases, the left and right contact points are periodically shifted and the amplitude of migration increases. Therefore, based on the droplet migration behavior and its force balance mechanism, a spring vibration model of migration behavior of the vibrating droplet micro unit was set up to predict the complete trajectory of its migration on a solid surface. The calculation results show that the theoretical displacement is less than the experimental displacement, and the longer the time, the larger the difference. Affected by the vibration, part of the droplet permeates through the micro-texture, resulting in the droplet losing height and the contact angle becoming smaller as well. While the other part of droplet overcomes the internal surface tension to migrate.

In this paper, we present a new texture image retrieval method which combines color and texture features extracted from images by a set of multi-resolution multi-direction (MRMD) filters. The MRMD filter set chosen is simple and can be separable to low and high frequency information, and provides efficient multi-resolution and multi-direction analysis. The color space used is HSV color space separable to hue, saturation, and value components, which are easily analyzed as showing characteristics similar to the human visual system. This experiment is conducted by comparing precision vs. recall of retrieval and feature vector dimensions. Images for experiments include Corel DB and VisTex DB; Corel_MR DB and VisTex_MR DB, which are transformed from the aforementioned two DBs to have multi-resolution images; and Corel_MD DB and VisTex_MD DB, transformed from the two DBs to have multi-direction images. According to the experimental results, the proposed method improves upon the existing methods in aspects of precision and recall of retrieval, and also reduces feature vector dimensions.

The bread added Lycii Fructus concentrate(10%) had a lightly dark surface with regard to the lightness of bread, especially Lycii Fructus experiment group was inclined to show low level in yellow chromaticity. The bread texture added Lycii Fructus concentrate was 163.3(g/㎠) in control group. The bread texture added Lycii Fructus concentrate(5%), Lycii Fructus concentrate(10%) was 152.9(g/㎠), 152.6(g/㎠) respectively in control group. In other words, from the result of its hardness, The bread texture added Lycii Fructus concentrate was more soften. The Sensual characteristic of bread added Lycii Fructus concentrate had significant differences in the items concerning the chromaticity, the swelled extent, the uniformity of air space, the flavorless, the softness, the sweetness, the bitter, the preference of bread. In the other hands, this researcher observed its added bread to the naked eye at room temperature(20$\^{C}$). Therefore, there observed with or without yeast in characteristics of stored bread, No yeast had ever been found over whole group for 6 days from the manufactured data. In the 8th days from the stored date, yeast began to be found in the whole group. Into the bargain, this researcher knew that the bread texture added Lycii Fructus concentrate(10%) generated yeast considering it added Lycii Fructus concentrate(10%).

Colour and texture are the most difficult quality aspects of Kimchi to maintain during storage. Therefore, this study investigated how to maintain superior quality Kimchi during fermentation without changes in color and texture. By examining differences between samples covered with vinyl(A group) and not covered with vinyl(B group) and assessing pH, total acidity, total viable cell count, total lactic acid bacteria cell count and sensory characteristics. The results are indicated that pH, total acidity, total viable cell and total lactic acid bacteria were similar between group A and B. Group A showed higher sensory score for colour, taste, texture and acceptability than group B(p<0.001). Covering the Kimchi with vinyl appeared to have a similar effect as when Kimchi is kept in a Kimchi-pot under stones or the outer leaves of vegetables making it possible to maintain good color and texture during storage. In conclusion, even though, it is not practical to use Kimchi-pots within urban settings today, vinyl coverings may offer the same effects.

전란(全卵)의 첨가수준을 달리하여 제조한 약과의 저장기간에 따른 기계적, 관능적 품질특성을 평가하였다. Texture profile analysis에 의한 물성특성의 경우 전란첨가량 및 저장기간에 따라 시료간에 유의적인 차이를 보였는데, 전란 첨가량 및 저장기간이 증가함에 따라 그 값이 증가하여 약과가 단단하게 경화되는 것으로 나타났다. 기계적 색도의 경우 전란첨가량에 따른 유의적인 차이를 보이지 않았으며, 저장기간이 경과함에 따라 약과의 명도 및 적색도는 증가하였고, 황색도는 감소하는 것으로 나타났다. 관능적 품질의 경우 관능검사 결과 약과의 종합적인 기호도는 10g의 전란 첨가시가 가장 선호되는 것으로 나타났으며, 30g 이상의 전란첨가는 관능적 품질을 저하시킬 수 있는 것으로 나타났다. 또한 약과에 전란첨가시 색, 외관, 맛, 풍미 등에는 큰 영향을 미치지 않는 것으로 나타났다.

The aim of this research was to develop a practical use of the citron (Citrus junos Sieb.) leaf, which is a by-product of the citron cultivation, by introducing it into the Jeolpyun, one of the most popular rice cakes in Korea. To achieve the goals of this research, the citron leaf Jeolpyun (CLJ) was first precipitated. The sensory properties and physical examination of products containing 0 (control), 1.0, 1.5, 2.0, and 2.5% of the dried citron leaf powders were then assessed by employing sensory evaluations and instrumental measurements for texture and color. A total of one-hundred and fifty women panelists in age categories of 20s, 30s, 40s, and over 50 were randomly selected from residents in the Seoul area. In general, the highest sensory evaluation scores were obtained for CJLs containing 2% of the citron leaf powders by all panel groups although there was some variation. As levels of the citron leaf powder in the CLJ increased, the texture parameters such as hardness, cohesiveness, and gumminess of the CLJ as measured by the Texture Analyzer significantly increased while adhesiveness decreased and springiness remained constant. Accordingly, the optimal amount of citron leaf powder was determined to be 2% or less for CLJ in order to maintain the original texture of the Jeolpyun. As the levels of the citron leaf powder increased in the CLJ, the Hunter colorimetric L-and a-value significantly decreased while the b-value significantly increased. In other words, the CLJs became darker, as well as deeper in green and yellow tones as the levels of the citron leaf powder increased. The above results indicate that the citron leaf could be successfully used for preparation of Jeolpyun at a concentration around 2%(w/w) based on the consumer preference test and instrument analysis of the products. This research is expected to contribute to the industrial use of citron leaf powder in Jeolpyun and other food products.

본 논문에서는 경계 중요도 맵과 영역 병합에 의한 영상 분할 방법을 제안한다. 경계 중요도 맵은 텍스쳐 경계 강도와 칼라 경계 강도의 조합에 의해 생성한다. 텍스쳐 경계 강도는 가버 필터 뱅크를 사용하여 다중 스케일과 방향에 따른 필터링 결과를 병합하여 생성하며 칼라 경계 강도는 HSI 칼라 모델의 H 성분에 대해 계산한다. 경계 중요 맵 영상에 대해서는 Watershed 변환을 통해 사전 영상 분할을 수행한다. Watershed 변환에 의한 영상 분할은 영역들이 과잉 분할되는 현상이 나타나므로 이를 개선하여 최종 영상 분할 결과를 생성한다. 이를 위해 우선 모폴로지 연산을 사용하여 경계 중요도 맵 영상에 대한 컨트라스트 향상과 마커 영역을 생성한다. 모폴로지 연산으로 과잉 분할 영역은 줄어들지만 여전히 상당수 존재하게 되므로 이를 극복하기 위해 영역 병합 과정을 수행한다. 영역 병합 단계에서는 영역 내부의 평균 칼라 및 가버 텍스쳐 벡터를 함께 사용함으로써 효과적으로 과잉 분할된 영역을 병합할 수 있도록 하였다. 제안한 방법은 다양한 자연 영상에 대해 실험하였으며 기존 방법과 결과를 비교하여 성능의 우수성을 확인하였다.
