  • The purpose of this study was to provide the basic information of making Skate pipyun made of skate skin. Test for quality characteristics of skate pipyuns seasoned with garlic, ginger, rosemary and basil were carried out. Hardness of GAR(4% of garlic and rosemary) was the highest, while that of GIB(4% of ginger and basil) was the lowest. As for the adhesiveness, springiness and cohesiveness, each specimen did not manifest significant difference. Water contents (82.43~85.56%) were no significant differences. The pipyuns added with spices and herbs were appeared weakly alkali with a range of pH 8.46~8.58. In the sensory evaluation, GIB was the most preferred in overall preference with significantly higher evaluation of flavor, savory taste, and lower fishy odor. The stability of gels decreased during storage at $10^{\circ}C$ for 8 hours, and at $20^{\circ}C$ for 60 min, and the greater was in GIB. Therefore, heating a mixture of 40% skate skin with 60% water for 10 min is recommended as optimum conditions for producing Skate pipyun.

  • Objective: In this study, we tried to investigate the antimicrobial activity of natural herbaceous plant-derived essential oils against oral disease-causing bacterial strains and establish the scientific evidences to apply them to the dentifrice, mouthwash, and other uses. Methods: We used the disk diffusion method with 23 types of 100% natural essential oils to verify the antimicrobial effect against Streptococcus mutans, Porphyromonas gingivalis, and Lactobacillus rhamnosus. After adhering to the surface of the plate culture medium, $20{\mu}l$ of the essential oil was prepared, and the diameter of the transparent ring was measured after incubation for 24 hours. All the experiments were repeated three times. Results: Among 23 types of oils, 13 were effective against all three strains: myrrh, ginger, basil, carrot seed, tea tree, patchouli, ylang ylang, cypress, lemongrass, cinnamon, peppermint, lavender, and eucalryptus. Seventeen oils were effective against S. mutans, and myrrh, basil, and carrot seed showed high antimicrobial activity. Eighteen oils were effective against P. gingivalis, and tea tree, carrot seed, and cinnamons showed high antimicrobial activity. Sixteen oils were effective against L. rhamnosus, and carrot seed and peppermint cinnamon showed high antimicrobial activity. Conclusion: Consequently, 13 essential oils showed the antimicrobial activity against three bacterial strains, which indicates these essential oils might be used as the effective materials to suppress the growth of oral-disease inducing microorganisms. Moreover, essential oils that have been analyzed activities in this study will be mixed up within the constant range and analyzed their antimicrobial effects to examine the synergistic activity among them.

  • The purpose of this study was to analyze the flavors of four fresh herbs(rosemary, basil, applemint, and majoram) and when they are fried, boiled, baked, and microwaved. Among the 18 flavors in rosemary, 37.40% was composed of ${\alpha}$-pinene(flavor of refreshing pine). The next highest composition of rosemary was 1,8-ci-neole(fresh, cool, sweet flavor) with 23.34%. In basil, 1,8-cineol had the most composition with 32.9%, and next was 3-hexen-1-ol(delicate floral fragrance) with 20.6%. When it was boiled, it barely had loss and when it was fired, only 10% of its flavor was left. Trans-${\beta}$-ocimene(camphoraceous and pine-like flavor) composed applemint with 16.66% and ${\beta}$-pinene(dry-woody and resinous-piney flavor) with 12.99%. Majoram was composed with 21 differrent flavors, 18.80% was composed of sabinene(spicy, woody-herbaceous flavor) and ${\gamma}$-terpine(citrusy flavor) composed 15.61% of majoram. Majoram had more flavor left when cooked compared to other herbs. In conclusion, rosemary and majoram had the most stability than other herbs, and boiling and baking left more flavor than frying them.

  • The selenium (Se) contents of 20 herbs, harvested in three areas in Korea, were analyzed. Many herbs had no Se. Angelica ($138.4{\mu}g \;Se{\cdot}kg^{-1}$ FW), caraway ($167.8{\mu}g \;Se{\cdot}kg^{-1}$ FW), chamomile ($116.6{\mu}g \;Se{\cdot}kg^{-1}$ FW), marjoram (158.7 and $132.6{\mu}g\;Se{\cdot}kg^{-1}$ FW), and oregano ($62.5{\mu}g\;Se{\cdot}kg^{-1}$ FW) accumulated Se as higher concentration compared with other plants. The Se content of herbs was dependent on the species, cultivars and areas. The status of Se uptake by herbs was investigated according to Se concentrations in hydroponics. During four weeks, before harvest of several herbs in greenhouse, sodium selenate ($Na_2SeO_4$) was added to the nutrient solution at concentrations of 2, 4, 6, and $8mg{\cdot}L^{-1}$. Field-mint accumulated Se too high, but external symptom of Se toxicity was not found. Essential oil content was generally proportionated to treated-Se concentration. The essential oil contents in basil and balm increased two to three times higher by sodium selenate treatment compared to non-treatment, but they did not show any linear relationship between essential oil contents and treated-Se concentration.

  • Objectives: Literature has shown that micro-organisms contaminate gutta percha (GP) during storage and manipulation. Till date herbal extracts are not explored as an alternative medicament for pre-operative chairside disinfection of GP cones. The purpose of our study was to evaluate the antimicrobial activity and efficacy of lemon grass oil (LG), basil oil (BO), and obicure tea extract (OT) in disinfecting GP cones before obturation. Materials and Methods: Agar diffusion method was used to evaluate the antimicrobial efficacy of LG, BO, OT, and sodium hypochlorite (control) against common contaminants, namely, Enterococcus faecalis, Staphylococcus aureus, and Candida albicans. One hundred and twenty GP cones were contaminated and cut into 2. First half was placed in the broth and incubated; whereas the second was treated with herbal extracts for 1 minute and then incubated for 24 hours in the broth. Any inhibition in bacterial growth was noted with presence/absence of turbidity. Two-way analysis of variance and ${\chi}^2$ test were used to assess the effectiveness of herbal extracts to decontaminate GP. Results: LG showed the highest inhibition zones ($29.9{\pm}6.9mm$) for all tested organisms, followed by OT extract ($16.3{\pm}1.8mm$), sodium hypochlorite ($16.0{\pm}1.6mm$), and BO ($14.5{\pm}5.3mm$). Statistically significant difference was observed between LG and other herbal extracts (p < 0.05). Conclusions: All extracts proved to be potential rapid chairside disinfectants of GP cones with LG showing the highest antimicrobial activity.

  • This study aims to increase the flavor of a lamb filet dish. The method used was as follows. Four kinds of crusts(mustard, herb & garlic, nuts, mushrooms) were made, and they were topped over lamb filet steaks. After cooking them, the good samples (mustard(MU3), herb & garlic(HG2), nuts(NC2), mushrooms(MC3)) by different materials through a sensory test were classified The selected samples were named as 1. Blank, 2. ECl(MU3), 3. EC2(HG2), 4. EC3(NC2), and 5. EC4(MC3). And then another sensory test was conducted targeting the samples to find out which crust had the best preference value. The results of the sensory test were statistically calculated Summarizing the results, all 4 kinds of samples topped with 4 different crusts showed much higher values than Blank, the control group. That indicates that the cooking method topping a crust on a lamb filet steak dish is very effective. Among them, the HG2 sample produced by mixing 70% of bread crumbs(115.5g) and 30% of garlic chop(49.5) with the base spice consisting of parsley 8g, rosemary 3g, basil 4g and olive oil 50g was evaluated as the best crust.

  • This article intends to shed a light on the British architect Arthur S. Dixon (1856-1929). He is largely regarded as a pioneer of the English Art and Craft Movement, yet his works are not widely known nor carefully studied. In search of Dixon's architectural characteristics, this paper examined three notable buildings that he designed at the turn of the nineteenth century; Birmingham Guildhall, St. Andrews church and St. Basil's Church. These buildings were erected relatively early in his career as an architect, although he never fully immersed into the profession due to his commitment in family business management. His architectural design shows unique qualities of Art and Craft movement in terms of use of material, spatial arrangement, techniques, and craftsmanship while employing Romanesque as most relevant historic style for ecclesiastical purposes.
