  • For this study, 18 kinds of cut and sew or seamless knitted test garment were made. Samples differed from each other by skirt angles($90^{\circ}$, $180^{\circ}$), gauges(7G, 12G, 15G), and grain directions(bias direction, wale direction, and radial direction). After measuring the mechanical properties of various gauges on the seamless knitting machine, I compared shape of the knitted flare skirt through subjective evaluation on appearances. The data analysis methods used in this study were descriptive statistics, one-way ANOVA, Duncan-test, correlation analysis, and regression analysis. The subjective evaluation on appearances of knitted flare skirts showed the following: In case of $90^{\circ}$ skirt, the seamless skirt showed a much higher score in every gauge expect that of the cut and sew 12G, and silhouette of 15G wale direction. In case of the $180^{\circ}$ skirt, the seamless type showed a much higher score in every item over the cut and sew expect the silhouette part of 7G wale direction.

  • This study identifies consumer needs and a pattern sensory evaluation of jacquard fabrics for raincoats using quick-drying-absorbing polyester. We investigate the consumer's consciousness and raincoat improvements. Twelve kinds of jacquard fabrics were developed for use in this study. Developed jacquard fabrics were assessed subjectively by 152 university students using a 7-point scale of 26 consumer needs and 31 pattern image sensory descriptors. Data were analyzed by SPSS. The major results were: There was a need for consumers to improve the front fastener type, cuff fastener, mesh patch position, and raincoat pocket position. The most important parameter to choose raincoat fabric was waterproof and the other parameters were vapor-porous/water repellent, design, color, fashionability, air-permeability and easy-put on/off. The pattern image sensibility of jacquard fabrics was explained by seven factors: gorgeous, simple, cute, futuristic, ethnic, feminine, and cool. A higher pattern preference was found in the jacquard fabrics of unique, sporty, natural, luxurious, and trendy images. The pattern preference was predicted at 45.3% with gorgeous, simple, pure, cute, futuristic factors. The correlation coefficient between the pattern image sensibility factor 1 (gorgeous) and pattern preference was 0.674 and with factor 3 (cute) was 0.416, and with factor 6 (cool) was 0.209. The 4 factors (gorgeous, simple, cute, futuristic) were selected as a significant pattern image sensibility that influenced preference.

  • The quality characteristics of dough and French breads containing dietary fibers, which were resistant starches (RS3 and RS4 types) and commercial non-starch polysaccharides (cellulose, pectin and chitosan), were investigated. The pH of the dough containing all dietary fiber except pectin was greater than that of control and was increased with increasing addition level. There was no correlation between pH and the expansion ratio of dough. As the level of added dietary fibers became high, the bread baking loss decreased, and the order of specific bread volume was 5% cellulose < 5% pectin < control bread, with no significant difference in specific volume. When a high level of dietary fibers was added to wheat flour, a complex phase appeared due to the formation between the network structure of additives and wheat gluten, and starch granules were heavily masted by the increased development of gluten-network matrix after the first fermentation like a wide spread net. Comparing the colorimetric changes of breads with the same added ratio (10%) of dietary fibers, the cellulose and RS4 addition breads had lower levels and the pectin-added bread had the highest value in the redness, while the chitosan-added bread had the highest value in the yellowness. Breads with a high level of dietary fibers showed increased hardness, gumminess, and brittleness and decreased springiness and cohesiveness. By sensory data, breads with 5% NSP and 10% RS addition showed high overall acceptability, with higher sensory RS score, compared to NSP addition. In conclusion, it was suggested that bread with lower than 10% RS or 5% NSP addition based on the amount of wheat flour, was acceptable with no considerable change in preference/overall quality and processing in bread-making.

  • The changes of the contents of chemical components and sensory evaluation of kimchi which were prepared by addition of different amount of ginseng were investigated during fermentation 50 days at $4^{\circ}C$. The data analysis revealed followings; 1. While saltiness was maintained at around 2.3% level during the entire fermentation periods. Kimchi containing 2% and 4% ginseng showed higher pH, reducing sugar, hardness by Instron and lower acidity than kimchi without ginseng. 2. Results from analysis of organic acids contains by HPLC revealed that all three groups contained relatively high concentration of oxalic acid, lactic acid and malic acid. 3. A result of sensory evaluation revealed that kimchi containing 2% and 4% ginseng was higher in hardness, savory taste and carbonated taste, and lower in sour taste, moldy off flavor than kimchi without ginseng, thus scoring high in overall eating quality. Considering all results obtained throughout this experiments, it can be concluded that the addition of small amount of ginseng to kimchi improve overall acceptability and retard rancidity thus increasing the period during which kimchi is eatable.

  • The study investigated the effect of prefermentation of Bifidobacteria longum and Lactobacillus plantarum on baking quality. Firstly, two kinds of prefermentation were cultured using two lactic acid bacteria, Bifidobacteria longum and Lactobacillus plantarum. White pan bread baked with dough that had undergone these two prefermentation methods was compared with that baked with a non-prefermented control. The physicochemical properties of the three breads were analyzed, and then the physicochemical and sensory properties of the dough and baked bread were cross-analyzed. The pH prefermentation of Bifidobacteria longum was lower than that of Lactobacillus plantarum, whereas the titratable acidity was higher. Compared to the results from analyzing the prefermentation of Lactobacillus plantarum, the prefermentation of Bifidobacteria longum was expected to give positive effects on enriching the bread flavor by creating acetic acid at a level three- to eight-fold higher than that of Lactobacillus plantarum. According to the mixogram data, the optimum ending time for both Bifidobacteria longum prefermentation and Lactobacillus plantarum was around 4.5 to 5 minutes. The speed of dough materialization decreased with increasing prefermentation culture time. The baked bread with added Bifidobacteria longum had a higher water content. However, the other contents were not influenced by prefermentation, but were by culture time. The specific loaf volume, oven spring and baking lass rate all peaked at 20 hours after culture for both prefermentation cultures. The sensory test results indicated the highest prefermentation for the bread baked with prefermented Bifidobacteria longum doughwith a culture time ranging from 20 to 26 hours. In addition, the bread baked with prefermented Lactobacillus plantarum dough gave the highest preference when cultured for 20 hours.

  • This study was conducted to develop methods of promoting traditional Korean Kimchi globally. To accomplish this, 99 Spanish natives were surveyed for their sensory evaluation and awareness of Kimchi. The results revealed that a relatively high number (46.9%) of the respondents had eaten Korean Kimchi. After eating the Kimchi, women tended to provide a slightly higher overall acceptability than men. Furthermore, when the overall sensory evaluation was conducted, the characteristics of Kimchi that were most recognized were its red color, spicy smell and hot taste. In addition, 93.9% of the respondents said that Korean Kimchi was a suitable food based on its spicy flavor>chewing force>appearance>red color>fermented smell. However, 6.1 percent of the subjects responded that they did not find Kimchi appetizing due to its hot taste>fermented smell>chewing force. Interestingly, the hot taste was a common selection for the reason that individuals liked or disliked Kimchi. When ranked among traditional Spanish foods, Kimchi was reportedly similar to cooked cabbage, cooked bell peppers, cooked red peppers and Moheu ppikan, pickles, Spanish lettuce, chiseutora and oil pickled cheese, or to various vegetables pickled in vinegar. Taken together, the results of this study should facilitate the globalization of Kimchi. In addition, the findings of this study provide fundamental data that should assist in the development of a local style of Kimchi for Spain.

  • This study was conducted to identify the sensory characteristics of four kinds of wild vegetables (samnamul, miyeokchwi, daraesoon and bangpung namul), which were prepared through three different soaking methods: SBS (soaking both before and after boiling), BS (soaking only after boiling) and B (never soaking). Moreover, it also compared the consumer acceptance of these samples in Korea. A descriptive analysis was performed on 12 samples (Sam_SBS, Sam_BS, Sam_B, Miyeokchwi_SBS, Miyeokchwi_BS, Miyeokchwi_B, Daraesoon_SBS, Daraesoon_BS, Daraesoon_B, Bangpung_SBS, Bangpung_BS and Bangpung_B) by 10 trained panelists. Furthermore, 115 consumers evaluated the overall acceptance (OL), acceptance of appearance (APPL), odor (ODL), flavor (FLL), and texture (TXTL) of the samples using a 9-point hedonic scale; they also rated the perceived intensities of toughness, roughness and moistness using a 9-point just-about-right (JAR) scale. According to the results of the PLSR data, the Sam_SBS sample, which had significantly (p<0.05) high muddiness, moistness, brightness, redness, oily appearance, sesame oil flavor, softness and greasy attribute scores, presented the highest acceptability and consumer desire scores for consumers. On the other hand, the Miyeokchwi_B and Bangpung_B samples, which had relatively high toughness, crispiness, roughness, bitterness and, astringent attributes scores, were the least preferred samples. Therefore, the muddiness, moistness, brightness, oily appearance, sesame oil flavor, softness and greasy attributes were drivers of "liking," whereas toughness, crispiness, roughness, bitterness, astringent attributes acted as drivers of "disliking" for consumers.

  • An autonomous car(driverless car, self-driving car, robotic car) is a vehicle that is capable of sensing its environment and navigating without human input. Autonomous cars can detect surroundings using a variety of techniques such as radar, lidar, GPS, odometry, and computer vision. Advanced control systems interpret sensory information to identify appropriate navigation paths, as well as obstacles and relevant signage. Autonomous cars have control systems that are capable of analyzing sensory data to distinguish between different cars on the road, which is very useful in planning a path to the desired destination. An issue tree, also called a logic tree, is a graphical breakdown of a question that dissects it into its different components vertically and that progresses into details as it reads to the right.Issue trees are useful in problem solving to identify the root causes of a problem as well as to identify its potential solutions. They also provide a reference point to see how each piece fits into the whole picture of a problem. Using Issue-Tree menthods, transportation safety policies were developed with autonompus vehicle in mind.
