  • The texture profile of frankfurter sausages was carried out by comparing the domestic(A) and imported(B) products. Fourteen character notes were identified: elasticity, surface moisture, surface smoothness, center hardness, skin toughness, cohesiveness, denseness, chewiness, moisture release, cohesiveness of mass, lumpiness, graininess, skin separation, and oiliness. Reference scales and the $0{\sim}3$ point numerical scaling method were also established. Panelists evaluated sausage A harder than the sausage B. It had higher skin separation and elasticity scores requring more chewing. Sausage B had lower surface moisture and cohesiveness of mass, but higher moisture release and graininess. Panelists commented that the sausage B were oilier but had milder tastes.

  • The purposes of this study were to measure the solubility of the stannous fluoride experimentally, to find a method for improving the solubility of the stannous fluoride, and to observe the effect of longterm storage on the variation of the concentration of fluoride in the stannous fluoride solutions. By adding such materials as antiseptics, dye, flavor, and tastes to solution, the variation of the fluoride concentration was also observed. Ten groups of 0.4% stannous fluoride solutions to which glycerine, sodium chloride, chlorhexidine, dye, flavor, xylitol, and sorbitol were added were prepared. The measurements were carried out by direct calibration. The obtained results were as follows. 1. Effect of adding glycerine as solvent. : The solubility of stannous fluoride increased in the case of adding glycerine. By increasing the glycerine concentration, the fluoride level in stannous fluoride solution also increased. 2. Effect of adding sodium chloride and chlorhexidine. : Comparing to the case of pure water, low fluoride level was measured in case of adding sodium chloride and high fluoride level was measured in case of adding chlorhexidine. 3. Effect of adding erythrosin as dye and banna essence as flavor. : Adding erythrosin and banna essence didn't affect fluoride level. 4. Effect of adding xylitol and sorbitol. : The effects of xylitol and sorbitol were nearly the same as the effect of adding erythrosin and banna essence.

  • As the music streaming service and the Hi-Fi market grow, various audio devices are being released. As a result, consumers have a wider range of product choices, but it has become more difficult to find products that match their musical tastes. In this study, we proposed a system that extracts the vocal component from the user's preferred sound source and recommends the most suitable audio device to the user based on this information. To achieve this, first, the original sound source was separated using Python's Spleeter Library, the vocal sound source was extracted, and the result of collecting frequency band data of manufacturers' audio devices was shown in a grid graph. The Matching Gap Index (MGI) was proposed as an indicator for comparing the frequency band of the extracted vocal sound source and the measurement data of the frequency band of the audio devices. Based on the calculated MGI value, the audio device with the highest similarity with the user's preference is recommended. The recommendation results were verified using equalizer data for each genre provided by sound professional companies.

  • The quality characteristics of doenjangs added with squid internal organs were evaluated. The contents of moisture, salt and amino type nitrogen were similar among traditional doenjang and squid doenjang(I, II, III). But the color values were different. pH and peroxide value(POV) were high in squid doenjangs. Squid doenjang(I, II, III) contained much taurine($53.26{\sim}170.90\;mg%$) and ${\alpha}-aminobutyric$ acid($35.17{\sim}151.00\;mg%$) which were not detected in traditional doenjang. Also aspartic acid and glutamic acid related to palatable taste, threonine, serine and proline related to sweet tastes were much more in squid doenjangs. Contents of isoleucine and leucine related to bitter taste were similar with traditional doenjangs. Comparing with traditional doenjang, volatile flavor components in squid doenjangs had high ratio of esters such as ethylbutylether and aldehydes such as 2-propanal, 3-methylbutanal in contrast with low alcohols. Especially ethylbutylether, 2-propanol, 3-methyl-1-butanal, 2,6,10,14-tetramethyl-pentadecane, ethyllinoleate were only in squid doenjangs. From the sensory evaluation after 4 weeks, squid doenjang(II) added with 10% squid internal organs obtained the highest scores for taste as differing from traditional soybean paste and squid doenjang(I). But the total acceptability was higher in traditional doenjang because of strong fishy smell and dark color in squid doenjang. After 8 weeks squid doenjang(I, II) obtained high scores for taste and low scores for color and flavor.

  • The purpose of this study is to decide the optimum amount of ginger, which draws attention as a functional food nowadays, to make ginger muffins and to serve the basic data for functional bakery products added with ginger juice. As measurement items for quality characteristics, I tested height, weight, volume, specific volume, moisture, pH, chromaticity, texture and organic functions of muffin by adding 10%, 20% and 30% ginger juice respectively comparing with general ingredients plus water amount used to make muffins. Height decreased with the amount of the addition increased, and there was no significant difference in weight. The volume and specific volume measurements of the muffins showed a lower value with the amount of the addition increased, which showed a significant difference. The moisture contents of the muffins increased with the amount of the addition increased. In the pH measurement, 0, 10, and 20% showed no significant difference while 30% showed a significant difference. Color measurement found that lightness and yellowness decreased with the amount of the addition increased, which showed a significant difference; redness showed high values, which indicated significant differences among all the samples. Texture measurement found that hardness showed significant differences among all the samples; cohesiveness showed a significant difference between the control and the treatment group; resilience/springiness increased with the amount of the addition increased. There were no significant differences in gumminess while chewiness increased with the amount of the addition increased. The sensory evaluation showed the lowest color with the amount of the addition increased; 10% addition was most preferred in flavor and taste; there was no significant difference in texture; there was no significant difference in 0, 10, 20% additions in overall acceptability. Taking the quality assessment and the sensory evaluation together, it is considered that general tastes of ginger muffins can be improved when ginger juice addition is 10% of water amount used.

Through this study, for vitalizing traditional Korean liquor market, the researchers attempt to explain the superiority of traditional Korean liquor and the advantages of using herbs to brew alcoholic beverages. Method : We conducted a research targeting traditional Korean liquors in domestic market from July through september 2012, and finally 70 kinds of liquor were selected and analyzed. Results : Among traditional liquors, fermented liquors are most common. When comparing regions of brewery, the central region of Korea, Gyeonggi-do and Chungcheongnam-do, is major brew area. 37 liquors contain just one medicinal herb. followed 10 liquors contain two medicinal herbs. The most frequently used medicinal herb is Ginseng Radix. And Lycii Fructus, Schisandrae Fructus, Angelicae Gigantis Radix and Chrysanthemi Indici Flos are well used medicinal herbs to brew traditional liquors. In the classification of efficacy of medicinal herbs, tonifying and replenishing medicinal herbs are most popular as ingredients in the traditional alcohols, astringent medicinal herbs, exterior releasing medicinal herbs and heat clearing medicinal herbs are also frequently used. Investigation of tastes and properties of the herbs, it reached a conclusion as below: sweet taste is most common, followed by sour taste and bitter taste. Warm property is account for 50% approximately, followed by cold property. Conclusion : Medicinal herbs have been widely used in the traditional Korean liquor. It came out into the open that the liquor with medicinal herbs is very good for our body in terms of longevity and invigoration. However, liquor consumers concern about not only the efficacy but also the taste, scent and color. Therefore, further study about these things would be required to demonstrate the superiority of the traditional Korean liquor.

  • The introduction of comprehensive programming channels has led to a diversity in the viewers' tastes and excessive competition between TV channels. Demand for channels on well-being is also increasing, due to the well-being and green consumption trends. This study conducted a case study on domestic and international channel branding strategies as well as an analysis on Korean channels focusing on well-being and lifestyle and found that there are no TV channels which provides comprehensive well-being information on food, clothing and housing at the moment in Korea. This study further discovered that information on such topics are currently provided in a tidbit fashion via educational or entertainment programs. Therefore, this study presented strategies for a well-being lifestyle channel brand and designed the brand mark and a station ID for the channel. This study conducted a survey targeting 50 men and women over 20 who have participated in environment-related projects for an objective verification of the channel brand strategies and design. The survey showed that the respondents were generally positive towards the necessity of the channel and of the content presented by this researcher. Some of the respondents, however, pointed out that the readability of the brand mark needs to be improved. This was reflected in the improved design and a survey comparing the two designs showed positive results. The results of this study will contribute to the launch of a well-being lifestyle channel targeting green consumers in the future.

  • Extracted from the metropolitan area, the Paldang Lake, which supplies approximately 8 million tons of water, has achieved a BOD (Biochemical Oxygen Demand) of 1.1 mg/L as a result of water quality preservation policies. However, concerning the COD (Chemical Oxygen Demand) component that encompasses refractory organic matter, there has been an observable upward trend in concentration. The introduction of refractory organic matter into the water source of Paldang Lake brings potential increments in BOD, generates off-putting tastes and odors in tap water, increases THM (Trihalomethane) formation, and triggers algae proliferation. Moreover, if residual hazardous refractory pollutants persist in aquatic environments, they may induce endocrine disruption and phenomena such as antibiotic resistance. In this study, a monitoring campaign was executed to discern the concentration of refractory organic matter emissions from point and non-point sources within Paldang Lake and its upstream region, with the aim of managing refractory organic matter in Paldang Lake. By comparing refractory organic matter emission concentrations across monitored areas, the elimination efficiency at wastewater treatment plants was assessed. Additionally, employing the Pearson correlation correlation analysis technique, correlations among refractory organic matter indices, antecedent wet days, and antecedent dry days were explored. The concentrations of refractory organic matter in rivers and Paldang Lake exhibited a similar pattern. Wastewater treatment plant effluents exhibited higher concentrations compared to rivers and Paldang Lake. The assessment of refractory organic matter removal at wastewater treatment plants indicated a removal efficiency of 65.73%. However, no significant correlation emerged between refractory organic matter emission concentration and antecedent wet days or priory antecedent dry days. This absence of correlation is attributed to data scarcity, underscoring the need for long-term monitoring and data accumulation.
