The artificial captions appearing in videos include information that relates to the videos. In order to obtain the information carried by captions, many methods for caption extraction from videos have been studied. Most traditional methods of detecting caption region have used one frame. However video include not only spatial information but also temporal information. So we propose a method of detection caption region using temporal and spatial information. First, we make improved Text-Appearance-Map and detect continuous candidate regions through matching between candidate-regions. Second, we detect disappearing captions using disappearance test in candidate regions. In case of captions disappear, the caption regions are decided by a merging process which use temporal and spatial information. Final, we decide final caption regions through ANNs using edge direction histograms for verification. Our proposed method was experienced on many kinds of captions with a variety of sizes, shapes, positions and the experiment result was evaluated through Recall and Precision.

Purpose: This study was undertaken in order to examine relations of eating disorders, health locus of control of college women, and to determine factors affecting eating disorders of college women. Method: The subjects were 282 students at a university in Busan. The instrument used for this study was a questionnaire on general characteristics, eating disorders (24 items), health locus of control (11 items) and self-esteem (10 items). Data were analyzed using means, percentages, t-test, ANOVA, Pearson correlation coefficients and stepwise multiple regression with a SPSS WIN 11.0 program. Result: Depending on BMI, there was no obese subject, 62.0% of the subjects were underweight, and 37.9% were normal. Over 40% of the subjects perceived them to be overweight while 62.1% of the women were underweight as defined by BMI. The total mean score of anorexia was higher than bulimia nervosa. There were significant differences in eating disorders according to BMI, perceived view of appearance, body satisfaction, experienced weight-control, and predictors of weight control method. Eating disorders showed a significant negative correlation with health locus of control and self-esteem. Stepwise multiple regression analysis revealed that the most powerful predictor of eating disorders was BMI. Experienced weight control, health locus of control and self-esteem and body appearance had significant effects on eating disorders. These predictive variables of eating disorders explained 27% of variance. Conclusion: The result of this study showed that eating behaviors among college women developed into eating disorders or were seriously disturbed. Therefore, to prevent eating disorders, health education should be provided to college women in relation to eating behaviors for health management.

The elderly population is rapidly increasing in South Korea, and interest in food development considering the Sasang constitution theory from oriental medicine and balanced nutrition is increasing. We developed the oriental medicinal porridges based on the Sasang constitution for the elderly. By Sasang constitutional medicine, Taeyangin has a large lung and small liver, and Soyangin has a large stomach and small kidney. Taeeumin has a small lung and large liver, and Soeumin has a small stomach and a large kidney. In this study, proper oriental medicine and food ingredients were identified, and a total of 12 oriental medicinal porridges were developed for 3 items by 4 Sasang constitution types. A single portion was developed based on about 600±66kcal, and the food ingredients were chopped. After cooking the menu developed based on the Sasang constitution, a sensory test was conducted. Five items, such as taste, appearance, aroma, texture, and overall preference, were evaluated on a 7-point scale. Sewage omegaenggul porridge among porridges for Taeyangin had the highest overall acceptance (6.17±0.7 points). Sukjihwang abalone black sesame porridge for Soyangin had the highest score(5.83±0.9 points). Sanyakyulmu hwangtae porridge for Taeeumin had the highest score(5.90±0.6 points). Ginseng chicken curry porridge among porridges for Soeumin had the highest overall preference in taste, appearance, aroma, texture, and overall acceptability (6.53±0.7 points). A limitation of this study was that the clinical trial could not be conducted on the elderly classified as Sasang constitution. In the future, the elderly will be able to have oriental medicinal foods according to the classification of Sasang constitution.

This study is based on the utilization of pine mushroom for processing products by development of pine mushroom Jung-Gwa. The results were summarized as follows: Pine mushroom Jung-Gwa were prepared with four different amounts (20, 30, 40, 50%) of honey. Pine mushroom Jung-Gwa color value was the highest by 20% soaking honey-water product and 40% soaking honey-water product was the lowest. Strength and hardness of 20% soaking honey-water product was the highest. Appearance to product of 50% soaking honey-water was the highest preference by all age of except 20's. The honey content of more and more external appearance preference was became higher. Product of 40% soaking honey-water was best by flavor of pine mushroom Jung-Gwa. A sugary tastes comparison 50% soaking honey water to 40% soaking honey water was not distinction. The texture was appeared a statistically significant difference by products of 20%, 30% soaking honey-water. Product of 20% soaking honey-water was favorite in 20's and product of 30% soaking honey-water was favorite in 30's. In overall preference test for pine mushroom Jung-Gwa of 40% soaking honey water was preferred by all age. Oligosaccharide helped geriatric diseases and cheaper. Thus this study used oligosaccharide but the result was not a statistically significant difference of pine mushroom Jung-Gwa products quality by comparison honey-water to oligosaccharide. Therefore oligosaccharide utilization products was thought worth a lot more by processing price and functional.

Since ISO 20471 regulations(2013) were enacted, high-visibility clothing made of fluorescent fabric and retroreflective materials has been standardized to distinguish the wearers from the surrounding background in a dark place and to protect them. Accordingly, we made high-visibility safety clothing based on the international standards, and examined the positions of the retro-reflective materials on the attached sites to evaluate the suitability of the positions, by 3 types of safety clothing and the body regions when the wearers work or move. Two retro-reflective films of 5cm-horizontal lines were attached to the front/back of the upper-wear, and the lower-wear. Vertical lines were attached from the shoulder to the horizontal waistline. To analyze the motion in 3-dimension, we took pictured infrared-reflective markers on the retro-reflective film covered with yellow-tape on the front-side when 6 subjects wearing experimental garments performed 6 types of motions. According to the metronome tempo, the motions were performed for 30 seconds and repeated 6 motions ①~⑥ by 3 experimental clothing. Among the 6 motions, significant differences in the appearance rate of the markers by body region during the motions were found in 5 types except for motion ③. Significant differences by the post-hoc test were shown in motions ④ and ⑥ as well. Therefore, for high-visibility safety clothing, it is necessary to anticipate the worker's motion and consider the attaching position of the retro-reflective material. It is considered desirable to attach the retro-reflective materials to several places where the clothing is hard to wrinkle.

Purpose: The purpose of this study was to clarify the panoramic image differences of cleft alveolus patients with or without a cleft palate, with emphases on the visibility of the line formed by the junction between the nasal septum and nasal floor(the upper line) and the appearances of the maxillary lateral incisor. Materials and Methods: Panoramic radiographs of 238 patients with cleft alveolus were analyzed for the visibility of the upper line, including clear, obscure or invisible, and the appearances of the maxillary lateral incisor, regarding congenital absence, incomplete growth, delayed eruption and medial inclination. Differences in the distribution ratio of these visibility and appearances were verified between the patients with and without a cleft palate using the chi-square test. Results: There was a significant difference in the visibility distribution of the upper line between the patients with and without a cleft palate (p<0.05). In most of the patients with a cleft palate, the upper line was not observed. In the unilateral cleft alveolus patients, the medial inclination of the maxillary lateral incisor was more frequently observed in patients with a cleft palate than in patients without a cleft palate. Conclusion: Two differences were identified in panoramic appearances. The first was the disappearance (invisible appearance) of the upper line in patients with a cleft palate, and the second was a change in the medial inclination on the affected side maxillary lateral incisor in unilateral cleft alveolus patients with a cleft palate.

This study examines options to revitalize a B2B textile trading platform, exploring user satisfaction and perceptions of the importance of several website features. Between June 8 and June 21, 2023, fashion studies majors and domestic fashion brand product planners were asked to use the website of an open B2B textile platform for 30 minutes and then evaluate its features by responding to a survey. The final sample for analysis wad comprised of 150 questionnaires. To analyze the key textile website features, a paired t-test, Importance-Performance Analysis (IPA), and multiple regression analysis were utilized. The analysis classified the key textile website features related to user importance and satisfaction into the following categories: convenience, appearance, product information, and uniqueness. An analysis investigation of the differences in importance and satisfaction for each website evaluation attribute found significant differences in 12 attributes. The IPA analysis revealed that attributes such as product reliability, quality, a convenient search function, and convenient page movement are highly important to users and garner high user satisfaction; these findings demonstrate the importance of maintaining these elements. Images on the main screen, the latest trend information, and product prominence attributes also garner high importance ratings, but result in low user satisfaction, which signifies extensive revision is required. Finally, user evaluation of the convenience, appearance, and product information of the website was found to affect user recommendation intention.

This study suggests ways to improve the standard test method and judgment criterion for the "Eco-toxicity Test" based on the rules and regulations provided in 'performance and qualifying test standards for marine pollution prevention materials and chemicals' in the Republic of Korea. Compared with the relevant references of other countries, this study attempted to find the limitations in the existing standards. As for the growth inhibition test of algae using Skeletonema costatum as an indicator, applying comparative analysis to measure specific growth rates, together with statistical analysis, instead of applying current methods, judged by the appearance of colors from the culture medium was suggested. Considering the exponential growth phase of the test species, the test duration was suggested to be reduced to less than four days. For the test with fish as an indicator, resetting the appropriate body size was suggested to, show consistent sensitivity against chenicals applied during testing. Furthermore, it is necessary to consider the criteria needs, which should be established in reasonable and objective ways. For the testing species, marine rotifer, Brachionus plicatilis could be a replacement for Artemia sp., and a bivalve for fish in the test. To improve the performance effectiveness of the "Eco-toxicity test", it is worth considering the designation of accredited testing institutes, by placing it in the same loop. Thus it is also expected to have a reliable management system in place, having the capacity of cost calculation properly and adjusting testing items if required.

Background The umbilicus makes an important contribution to the natural appearance of the abdomen. To date, studies on its position in Korean women are lacking, and no standards have been established. The purpose of this study was to investigate the position of umbilicus in Korean women and to review changes in its position after ipsilateral pedicled rectus abdominis musculocutaneous (IP-RAM) flap. Methods This research consisted of two studies. In first study, 100 females who visited the emergency department with gastroenteritis between 2007 and 2011 were included. In second study, 40 women who underwent IP-RAM flap in the same period were included. Using abdominal computed tomography, we measured the distance between xiphoid process and umbilicus, represented by value a, and the distance between umbilicus and symphysis pubis, represented by value b. Thus, the location of the umbilicus was represented by the ratio a/b. The data were analyzed using Pearson correlation test and paired t-test. Results In study 1, the mean value of a/b was 1.07. Pearson correlation test revealed a significant correlation between age and a/b. In study 2, the mean value of a/b was 1.16 in preoperative measurements and 1.01 in postoperative measurements. The paired t-test showed a significant difference between preoperative and postoperative measurements, indicating cephalic migration of the umbilicus after surgery. Conclusions The natural position of the umbilicus showed caudal migration with aging. Additionally, in a comparison of preoperative and postoperative measurements in patients who underwent IP-RAM flap, cephalic migration of the umbilicus was observed after surgery.

The purpose of this study was to promote consumption of rice through production of jeungpyun added with blueberry attracting attention as a functional food material and to develop a functional blueberry supplement suited to the preference of Westernized consumers. For that pupose, we performed physicochemical quality test and sensory test after preparing the jeungpyun added with blueberry powder based on a ratio of 1%, 2%, 3%, and 4% of rice flour. The results of this experiment can be summarized as follows. When the addition of blueberry powder increased, the moisture content in jeungpyun decreased, but there was no significant difference between the samples. The lightness and the yellowness related to chromaticity decreased and redness increased when the addition of blueberry powder increased. The pH of the dough in jeungpyun increased significantly (p<0.001) when addition of blueberry powder increased. As the fermentation progressed, the pH tended to decline. The volume of dough decreased when addition of blueberry powder increased. The volume was the highest after the first fermentation, and decreased after the second fermentation. Viscosity decreased significantly as the addition of blueberry powder increased, and increased as fermentation time increased, and decreased after the third fermentation. A test was conducted to determine difference in characteristics, and the results showed that the color intensity, cell uniformity, blueberry flavor and sweetness were strong when the addition of blueberry powder increased. The results of preference test showed that JB3 containing 3% blueberry powder had the best appearance, flavor and overall acceptance.
