  • This study was conducted to develop the evaluation model which can analyse local agenda 21 comprehensively and systematically from the making process to the designed contents. The evaluation model was devised through the theoretical review of local agenda 21 and designing the evaluation system composed of evaluation domains, related indicators and scales. The evaluation system was carefully constructed based on planning theories and the discussion and agreement of specialists regarding local agenda 21. This model has three evaluation domains of process, content, and evaluation of implementation with different weighting values. Each domain contains large indicators, medium indicators and small indicators. Each indicator has different weighting value according to its importance. Basically, each small indicator was scored by 3 or 5 point scale. This evaluation system can not only analyse local agenda 21 quantitatively, but also find out good points, problems, and limits of various phases of planning and implementing local agenda 21.

  • This paper presents a new framework for integrating untranscribed spoken content into the acoustic training of an automatic speech recognition system. Untranscribed spoken content plays a very important role for under-resourced languages because the production of manually transcribed speech databases still represents a very expensive and time-consuming task. We proposed two new methods as part of the training framework. The first method focuses on combining initial acoustic models using a data-driven metric. The second method proposes an improved acoustic training procedure based on unsupervised transcriptions, in which word endings were modified by broad phonetic classes. The training framework was applied to baseline acoustic models using untranscribed spoken content from parliamentary debates. We include three types of acoustic models in the evaluation: baseline, reference content, and framework content models. The best overall result of 18.02% word error rate was achieved with the third type. This result demonstrates statistically significant improvement over the baseline and reference acoustic models.

  • To determine the sodium content of meals provided by foodservice institution, 540 different menus were collected by their serving portion and categorized into nine food groups and three different foodservice types (office, industry, school). Each were evaluated by each sodium evaluation method. All nine categories of food type showed higher content of sodium than listed in the 'nutrition assessment program (Can-Pro 4.0)', when assessed with a salimeter. From the 9 food types, 6 types, excluding 'Korean pancakes', 'Kimchi/pickled food' and 'a la carte', showed significantly higher sodium content on the salimeter than shown in the 'nutrition assessment program (Can-Pro 4.0)' (p<0.001). Also in assessing sodium content per serving, 'soup and stews' and 'a la carte' menus had significantly higher sodium content than other food types (p<0.001). The results compared by foodservice types showed dishes served in 'Industries' had significantly higher daily sodium content than those served in 'offices' and 'schools'.

  • This study involved the production of specialty lager beers supplemented with Korean red ginseng extracts or Bokbunja (Korean black raspberry, Rubus coreanus Miquel) juice. The effects of the Korean red ginseng extracts or Bokbunja juice on the specific gravity, pH, yeast viability, free amino nitrogen content, reducing sugar content, color, alcohol content, turbidity, and sensory evaluation were evaluated. The alcohol content of the beers containing the extracts or juice were within the standard alcohol amounts (3.63-4.0%, v/v). The pH values of the three samples containing Bokbunja juice were lower than that of the control values. The sensory evaluation showed that the addition of Bokbunja juice was superior to the ginseng extracts, and the optimal addition time was before or after the secondary fermentation. These data indicate that the flavor and odor of the Bokbunja juice are more persistent than that of the ginseng extracts.

  • The aims of this study were to develop $macaron{\grave{e}}$ with Korean red pepper (Capsicum annuum L.) and GABA (${\gamma}$-aminobutyric acid) rice powder and analyze their physico-chemical and physiological characteristics. Korean red pepper (Capsicum annuum L.) was added to $macaron{\grave{e}}$ at a weight percentage of 0, 2.5 and 4.5%. Color values (L-value, redness, and yellowness), total sugar content, total phenolics, total carotenoids, ABTS radical scavenging activity, textures, and sensory characteristics with varying various Korean red pepper were measured. As the ratio of the powders in the $macaron{\grave{e}}s$ increased, total phenolic content, total carotenoid content, and radical scavenging activity increased. There were significant differences in total phenolic and total carotenoid content of $macaron{\grave{e}}s$ (p<0.05). Sensory evaluation indicated significant differences (p<0.05) in color, sweetness, texture, and overall acceptability depending on the addition of Korean red pepper. KR30 $macaron{\grave{e}}$, showed higher overall acceptability, as compared to other $macaron{\grave{e}}$.

  • The quality characteristics of Omija (Schizandra chinesis Baillon) extracts under various extraction temperatures and times were examined. The pH level of the extracts ranged from 3.35-3.47. The sugar and solid content of the samples significantly increased with increasing extraction temperatures and times (p<0.01). In contrast, the lightness of the extracts decreased with increasing extraction temperatures and times (p<0.001). In a palatability test, extracts boiled at $80^{\circ}C$ for 30 minutes scored high in terms of color, flavor, turbidity, sourness, and overall acceptability. Hydroxy radical scavenging activity and polyphenol content of the extracts significantly increased with increasing extraction temperatures and times (p<0.01). Furthermore, direct correlations between hydroxy radical scavenging activity and polyphenol content (or flavonoid content) were established through simple regression (r>0.9) for different extraction temperatures and times. From these results, extracts boiled at $80^{\circ}C$ for 120 minutes is the best to product omija beverage considering functionality and sensory evaluation as well.

  • The purpose of this study was to investigate the quality characteristics of fish paste added with different amounts (0%, 0.5%, 1%, 1.5%, and 2%) of spirulina powder. Specifically, moisture content, pH value, color value, texture value, total polyphenol content, DPPH radical scavenging activity, and sensory evaluation were measured in the samples. The moisture content of the fish paste added (0.5%, 1%, 1.5%, and 2%) ranged from 68.60% to 69.03%, and the increased amounts of spirulina powder in the fish paste tended to decrease the pH value. For the Hunter color values, the L, a values of surface and inside of the fish paste decreased with increased amounts of spirulina powder. The b values of the fish paste increased with increased amounts of spirulina powder. In the texture meter test, the hardness, gumminess, and adhesiveness decreased with the increased amounts of spirulina powder, and chewiness of group adding spirulina powder was measured lower than control. Springiness of the fish paste did not appear statistically significantly different among the samples according to the increased amounts of spirulina powder. Total polyphenol content of fish paste added with spirulina powder increased with increased amounts of spirulina powder, and DPPH radical scavenging was heightened according to increased amounts of spirulina powder. In sensory evaluation, the addition of 1% spirulina powder had the best score in odor, texture, taste, and overall preference. These results suggest that spirulina powder can be applied to fish paste to increase quality, preference, and functionality.
