        Swine atrophic rhinitis is a respiratory disease that causes nasal turbinate loss and septal deformation due to Bordetella bronchiseptica and Pasteurella multocida. Turbinate loss facilitates pathogens to infect lungs, which leads to various respiratory diseases and productivity reduction. In this study, descriptive analysis was implemented for atrophic rhinitis and pneumonia. From 6 pig farms shipped to slaughterhouses in Chungbuk province, 20 heads and 20 lungs were collected by each farm from March 2020 to September 2020. Their atrophic rhinitis lesions and lung lesions were scored and blood samples were also collected to test the seroprevalence of several respiratory diseases. Pasteurella multocida from nasal swab was cultured and antibiotic resistance tests were performed. Correlation between atrophic rhinitis scores and lung lesion scores was not found. Abdominal nasal lesions were more severe than dorsal lesions. Differences in lung lesion scores were relatively small between lobes. The score of pneumonia was higher in castrated pigs than in female pigs. There was no relationship between lesion score and seroprevalence of respiratory diseases. Antibiotic resistance levels for Pasteurella multocida differed by farm, and several antibiotics were not effective. The results of this study imply that antimicrobial susceptibility tests are highly recommended before administration.

        This study evaluated the sensory characteristics of sauerkraut prepared by adding 0.5, 1.0, 1.5, 2.0, and 2.5% (w/w) sea salt to cabbage. The quantitative descriptive analysis (QDA) and acceptance test of sauerkraut were determined for each salt concentration, and the principal component analysis (PCA) and partial least square regression (PLSR) analysis were performed to confirm the correlation between each factor. Results of the QDA determined 14 descriptive terms; furthermore, brightness and yellowness of appearance and the sour, salty, and bitter flavors differed significantly according to the salt concentration. Results from the PCA explained 22.56% PC1 and 65.34% PC2 of the total variation obtained. Sauerkraut prepared using 0.5, 1.0, and 1.5% sea salt had high brightness, moistness, sour odor, green odor, sour flavor, carbonation, hardness, chewiness, and crispness, whereas sauerkraut prepared with 2.0 and 2.5% sea salt had high yellowness, glossiness, salty flavor, sweet flavor, and bitter flavor. Hierarchical cluster analysis classified the products into two clusters: sauerkraut of 0.5, 1.0, and 1.5%, and sauerkraut of 2.0 and 2.5%. Results of PLSR determined that sauerkraut of 1.0 and 1.5% were the closest to texture, taste, and overall acceptance. We, therefore, conclude that sauerkrauts prepared using 1.0 and 1.5% sea salt have excellent characteristics in appearance, taste, and texture.

        The aim of this study is to investigate the relationship between the sensory characteristics and protein concentration of enzymatically hydrolyzed isolated soy protein. As a result of QDA, 34 attribute descriptors were developed. According to the results of the flavor profile, the strengths of most color and tastes except sourness were evaluated before activated carbon treatment sample. Principal component analysis (PCA) was performed to summarize the relationship between attributes and samples. The result of PCA was 56.35% (F1) and 35.05% (F2), having explained 94.13% in total variablility. In case of the untreated sample of active carbon, it was located in the first quadrant and correlated with color, flavor, a slightly salty taste, and a slightly bitter taste. It also showed high correlation with meju taste. The activated carbon treatment samples were located in the second quadrant and correlated with delicate taste, slight saltiness, sourness, and umami, having high correlation with burned rice.

        In this study, we used a choropleth map to explore the spatial variation of the risk of cattle herds being bovine tuberculosis (BTB) positive in Gangwon-do in 2015. The map shows that the risk of being BTB-positive was lower in provinces located in the middle of Gangwon-do (Wonju, Youngwol, Peongchang, and Kangneung) than in other provinces. In addition, one province located in the north (Goseong) had a low risk of BTB. The estimate for the intercept of the spatial lag model was 0.66, and the spatial autocorrelation coefficient (lambda) was 0.20 (Table 1). The Moran’s I was 0.33 with p-value of 0.02. In 2015, provinces located in the North West (Hwacheon) and East (Donghae) of Gangwon-do had a higher BTB risk. We identified some specific provinces at low BTB-positive risk, information that may prove useful for control of BTB in the study area.

        High pressure and enzymatic hydrolysis was applied to anchovy in order to produce a natural seasoning salt enhancer. The purpose of this study is to investigate the relationship between the sensory characteristics and protein concentration of enzymatic hydrolysates with anchovy. According to the results of QDA, 24 attribute descriptors were developed. Based on the flavor profile, the strengths of most tastes, except sourness, color flavor, and odor were evaluated before activated carbon treatment. Principal components analysis (PCA) was performed to summarize the relationship between attributes and samples. The result of PCA was F1 72.13% and F2 22.01%, having explained 94.13% in total variability, as F1 was shown according to the correlation about activated carbon treatment before or after samples. The characteristics of color, flavor/odor, and saltiness or bitter taste had higher correlation before activated carbon treatment samples. Also, F2 was shown to have no correlation to the samples.

        The objective of this study was to determine sensory profiles of rice confections. The samples used in this study obtained from Korea (traditional Korea rice snack and local specialty rice snack) and three countries (USA, Japan, and China) were evaluated and compared. The sensory characteristics of five kinds of rice confections were evaluated using a sensory test and were analyzed via quantitative description analysis (QDA), principal component analysis (PCA), and hierarchical cluster analysis (HCA). In the descriptive analysis, 10 trained panelists evaluated sensory characteristics consisting of 19 attributes, and there were significant differences (p<0.05) among the 16 characteristics. For the descriptive data, multivariate analysis of variance was carried out and identified differences among the samples. The PCA of rice confections for the first two principal components could explain 85.66% of the variations. The Korean, Japanese, and Chinese rice confections were savory, gritty, and particle-sized, the other Korean local specialty rice confections were fruity, sweet, honey-flavored, compact, and crispy, and those from the USA were glossy, grainy, bright, adhesive, cohesive, crispy, and sweet.

        The objective of this study was to develop a reliable and reproducible descriptive analysis procedure for Korean style sweet pumpkin gruel (Hobakjuk). The sensory attributes of the sweet pumpkin gruel were developed and defined, the sample preparation method was standardized, and the sensory evaluation procedure for a sample was established. Seven types of sweet pumpkin gruel (five ready-to-eat type vs. two ready-to-heat type) were selected to be analyzed. Panel training and descriptive analysis were carried out with these 7 samples. A total of 12 sensory attributes (2 aroma/odor, 5 taste/flavor, 4 texture/mouthfeel, and 1 aftertaste attributes) were developed to describe the sensory characteristics of the sweet pumpkin gruel. The definition and reference standards for each sensory attribute were determined to clearly understand each attribute. In the main experiment, trained panelists evaluated the sensory characteristics of the 7 gruel samples based on a fifteen-point intensity scale using the developed attributes. The results were statistically analyzed by analysis of variance, principal component analysis, and cluster analysis. The results showed that the 7 sweet pumpkin gruel samples significantly diffieredin their intensities of all attributes except for sweet pumpkin aroma and viscosity. The ready-to-eat style samples were distinctly characterized by their sweet pumpkin aroma and flavor, whereas the ready-to-heat style samples were markedly characterized by their low intensity of gelatinized starch and pumpkin flavor retention.
