  • This study was examined the optimization of processing conditions for taste-assurance factors of boiled Korean native chicken (KNC) through response surface methodology. The effects of two independent variables, including heating time ($X_1$) and water volume ($X_2$), were investigated using central composite design. Hypoxanthine content, lipid oxidation, texture, and sensory results were chosen as dependent variable. Results showed high reliability on hypoxanthine and texture property in leg meat (not breast meat) of boiled KNC. Statistical modeling revealed that 3.5 folds of added water (v/w) based on chicken weight and 73.5 min of cooking time was the optimum for producing characteristic taste and textural properties from the leg meat of KNC.

  • To make rice cake with squid ink, the squid ink dilulted in fifteen times was added to rice flour in the ratio of 0%, 2%. 4%, 6% and 8% respectively. Then, the squid inky rice cake was tested in physical function and chromaticity. Rheometer test was also included in this experiment. In physical function test, it showed that the inky rice cake with 6% and 8% ratio was the best in preference. In the chromaticity test, as the adding ratio of squid ink increases, the brightness decreased. The red and yellow brightness of 8% inky rice cake showed high. The results of rheometer test are as follows. In hardness, the inky rice cake with 2% adding ratio was high and the 6% inky rice cake was low. In cohesiveness, the 0% inky rice cake was high and the 8% inky rice cake was low. In gumminess, the 2% inky rice cake was high and the 6% inky rice cake was low. In brittleness, the 2% inky rice cake was high and the 6% inky rice cake was low. With correlation analysis, 1 could reach the following. The overall quality of inky rice cake was correlated with all test items except chewiness. The moistness was correlated with flavor, grain and chewiness. Also, the 8% inky rice cake was correlated with the inky rice cakes with the other adding ratios in all aspects of test. Futhermore, in the results of rheometer test. the hardness was correlated with the other three kinds of characteristics.

  • Codonopsis lanceolata serves as, an appetizing health food for its, characteristic flavor, taste, and texture:however, it requires a long and complicated cooking process. Therefore, this study conducted pre-processing procedures to improve the cooking process and Codonopsis lanceolata more easily. For processing efficiency, freezing and blanching were efficient for peeling and the rate of peel disuse. In addition the freezing process, effectively reduced the time spent in beating raw material. In the salinity test, freezing and blanching quickly increased salinity over 28 days. As the result of SEM cross-section tests showed that frozen Codonopsis lanceolata become porous, it's assumed that seasoning permeates into this cross-section efficiently. As the appearance of Deodeok-gui as significant differences according to the pre-processing methods, this study examined pre-processing methods(time spent in peeling, rate of peel disuse, time spent in beating out material, salinity, moisture content, texture, and the color) of Codonopsis lanceolata. After testing Deodeok-gui, it was found that freezing is effective, not only for process efficiency and cooking time reduction, but also for improving its qualities.

  • In this study we propose a new texture feature extraction method based on an estimation of the brightness and structural uniformity of CT images representing the important characteristics for emphysema recognition. The Center-Symmetric Local Binary Pattern (CS-LBP) is first used to combine gray level in order to describe the brightness uniformity characteristics of the CT image. Then the gradient orientation difference is proposed to generate another CS-LBP code combining with gray level to represent the structural uniformity characteristics of the CT image. The usage of the gray level, CS-LBP and gradient orientation differences enables the proposed method to extract rich and distinctive information from the CT images in multiple directions. Experimental results showed that the performance of the proposed method is more stable with respect to sensitivity and specificity when compared with the SGLDM, GLRLM and GLDM. The proposed method outperformed these three conventional methods (SGLDM, GLRLM, and GLDM) 7.85[%], 22.87[%], and 16.67[%] respectively, according to the diagnosis of average accuracy, demonstrated by the Receiver Operating Characteristic (ROC) curves.

  • In literature it is not only the meaning of words which matters, but also their texture matters i.e. their rhythm, colour and style are relevant and none of these natures can be reduced to an item of information. The texture is also important in film languages, especially the rhythm. In order to make the storytelling rhythm visible, a new concept of 'the Rhythm Chart Analysis Method (RCAM)' has been devised in this research and used for analysis. By analyzing original films and remakes in Korean and Chinese, one can find out that different countries have different storytelling rhythms i.e. the same story can be told in different rhythms. The central idea in Korean films is portrayed at the end, which is a typical characteristic of Korean films. And as the defining moment does not occur suddenly the audience can naturally get immersed into the story. But Chinese films communicate with the audience in a more direct way. It directly mentions characteristics of each actor in such a way that it is telling rather than showing. The information of the movie is given to the audience in the initial stages of the movie. Rhythm is as important as story and information. And through this we can find out the cultural differences from the different storytelling rhythms.

  • LBP 알고리즘은 지역적 질감표현이라는 특성을 가지고 있기 때문에 기준영상과 샘플 영상의 추출 위치와 크기에 따라 전혀 다른 결과를 얻을 수 있다. 이러한 단점을 해결하기 위하여 본 논문에서는 먼저 LBP 기본특성을 조사하고, 기준영상(100×100)의 크기를 영상내의 대부분의 특성을 포함할 수 있도록 하고, 임의의 지점에서 추출된 샘플영상(40×40)을 선택한다. 기준영상의 LBP와 샘플영상의 LBP 간의 상관관계를 이용하여 기준영상의 LBP에서의 매칭위치를 찾은 후, 카이분석 방법을 사용하여 샘플영상과 가장 일치하는 기준영상을 찾는 방법을 제시한다.

  • The changes of the color, texture and volatile flavor compounds of Yu-gwa were investigated that affected by the oxidation during storage to characteristic Yu-gwa quality. Among the proximate compositions, carbohydrate was the most abundant component, and followed by lipid and moisture. Although the change of the color showed different pattern by the packaging materials during the storage period, the value of yellowness(b) increased but that of lightness(L) decreased dramatically after 3 month storage. In the textural properties reported closely related with the moisture content, hardness was fairly affected on the period of the storage rather than the type of packaging materials. The flavor compounds of Yu-gwa were analyzed to evaluate the change of distinct volatile compounds during storage. Of the twenty one separated volatile compounds, major volatiles were aldehydes, alcohols and alkenes. The results also showed that polyethylene(PE) contained less volatiles than polypropylene(PP) by the oxidation process during storage.2,4-Decadienal was gradually increased with the period of the storage, whereas octane and furan were decreased. The results provided that the change of the flavor distribution during the storage, and also the possibility of the volatiles such as hexanal, nonanal and 2,4-decadienal as the indicator for the oxidation process.

  • 조기 유방암을 진단하기 위해서는 유방초음파 판독이 매우 중요하다. 초음파 검사는 초음파장비에 따라 화질의 차이가 심하게 나타날 뿐만 아니라 검사자의 경험과 숙련 정도에 따라 진단의 차이가 크게 나타난다. 따라서 정확한 진단과 치료를 위하여 객관적인 판단기준이 필요하다. 이에 본 연구에서는 GLCM(Gray Level Co-occurrence Matrix) 알고리듬을 적용하여 질감 특성을 분석하고 특징파라미터들을 추출하여 신경망분류기를 이용하여 유방암을 진단하였다. 유방초음파 영상은 정상 조직과 양성, 악성 종양으로 분류하여 질감 특성 파라미터 6가지를 추출하였다. 유방초음파검사로 진단된 정상 영상, 악성 및 양성종양 영상 각각 14증례를 대상으로 추출된 6개의 파라미터들을 적용하여 다층 퍼셉트론 신경망구조 역전파 학습방법으로 학습을 시켰다. 학습된 모델에 정상 유방 영상 51증례, 양성종양 영상 62증례, 악성종양 영상 74증례의 영상을 사용하여 분류한 결과 95.2%의 분류율을 나타내었다.

  • 김치제조에 사용되는 결구포합형 배추의 구조와 그 조직감 특성을 조사하는 방법을 연구하였으며 소금절임, 가열데침 공정등에 의한 배추임의 구조적 변화와 조직감 변화를 조사하였다. 배추잎의 형성순서에 따라 잎의 길이와 두께는 비례적으로 증가하였으며 두께는 최외엽에서 다소 감소하는 현상을 나타내었다. 배추잎의 미세구조는 밀집된 유관속조직 주위에 유조직 세포가 쌓여있는 형태로서 절단시험에서 외피와 유관속조직의 특징적인 절단력 곡선들을 나타내었다. 절임과 데침처리에 의하여 배추잎의 절단력은 증가하였으며 이것은 주로 세포벽의 구조적 변형에 따라 포개짐에 의한 절단면의 수적 증가에 의한 것이었다.

  • 쌀의 수침시간과 증자시간이 가래떡의 품질에 미치는 영향을 살펴보았다. 쌀의 수침시간이 증가할수록 수분흡수율과 고형분 함량이 증가하였고, 입자크기는 8시간과 10시간 수침한 쌀가루의 입자가 $<40\;{\mu}m$ 크기에서 $75.2\~76.8\%,\;40\~100\;{\mu}m$ 크기에서 $23.2\~24.8\%$로 나타나 수침시간이 길어질수록 제분시 입자크기가 작아졌다. 가래떡을 제조하는데 있어 최적의 수침시간과 증자시간을 알아보고자 살펴본 가래떡의 조직감, 색도, 관능검사에서는 증자시간에 길수록 조직의 경도와 응집성, 검성, 씰힘성 등이 감소하였고, 탄성의 경우 40분 증자하였을 때 가장 높게 나타났다. 색도에서는 증자시간이 길수록 L값을 감소시키고, b값을 증가시켜, 8시간 이상의 수침시간과 40분의 증자시간이 적당한 것으로 나타났다. 또한 관능검사를 통하여 흰색의 강도(whiteness), 경도(hardness), 탄성(spinginess), 씸힘성(chewiness) 및 전반적인 기호도(overall acceptability)를 측정한 결과 8시간의 수침시간과 40분의 증자시간이 최적인 것으로 판단되었다.
