The utilization of coatings composed of bio-based materials in the processing and preservation of meat presents an environmentally conscious, secure, cost-effective, and superior method for prolonging the storage life of meat while also preserving its nutritional value. In this study, changes in physical, chemical, and microbiological characteristics of freshly cut beef coated with distilled water (control) and keratin-starch composites (K-S) functionalized with 0.0-, 0.2-, 0.6-, and 1.0-mL avocado peel polyphenolic-rich extract (APPPE) kept at 4℃ for 12 days were evaluated periodically at 3-day interval using standard techniques. Keratin was extracted from waste feathers, while starch was obtained from ginger rhizomes. Following a 12-day storage period, beef coated with APPPE-enriched K-S composites exhibited a significant (p<0.05) improvement in shelf life by minimizing deteriorative changes in pH and color (as determined by metmyoglobin level) in addition to inhibiting oxidative changes in lipids (as determined by TBARS level) and proteins (protein carbonyl level) in comparison to control and K-S composite without APPPE. Furthermore, microbial growth was significantly (p<0.05) suppressed in meat coated with K-S composite functionalized with APE at 0.6 and 1.0 mL compared to the control. The study suggested that APPPE-enriched K-S composite could offer an eco-friendly and safe food preservation technique for fresh meat.

Background: The recent outbreak of the novel strain of influenza A (H1N1) virus has raised a global concern of the future risk of pandemic. Traditional Korean Medicine(TKM) has been combatting against contagious diseases and developed its own particular and efficient way in treating those diseases. Objectives: Provide a distinctive and effective TKM method in understanding the principles of treatment, prevention, and contraindications against influenza A through case histories. Method: We revised case histories of eminent doctors of Ming and Qing dynasties according to their clinical manifestations similar to those of influenza A. We also verified prescriptions of the "Dong-uibogam(東醫寶鑑)" through examining clinical practices of China today. Results: 1. The subtypes of Warm disease; Wind Warmth and Pestilence has the most similar clinical manifestation in comparison to Influenza A. Specifying these terms is important in recognizing and classifying various diseases under the name of Warm disease. 2. TKM considered not only external factors but also individual factors like general condition, diet, emotion, constitutional types, etc in the treatment of febrile diseases. 3. TKM developed a new way in the treatment of contagious diseases. considering the characteristics of each pathogen. TKM described the Warm pathogen being light as a feather, which enters through the nose, principally affecting the Lung. Therefore, they emphasized treatment with Pungent Sweet Cooling Moistening[辛甘凉潤] method. 4. As the conservation of fluid and humor is the primordial concern in the treatment of Warm disease, they restricted release of the exterior with pungent-warm and purgation method. The purgation methods was used exclusively to decrease fever and preserve fluid and humor. 5. The only differentiating characteristics of Influenza A with seasonal influenza are vomiting and diarrhea. Case research revealed the possibility of these manifestations to be a mechanism of restoration. 6. TKM provides alimento prevention method like Mint Pear Porridge, mung bean, and etc also combination of herbal medicine. Also emphasized in the conservation of essence for the prevention of contagious diseases. Conclusions: TKM developed its unique way in understanding the pathogenesis, diagnosis, treatment, and prevention of contagious diseases and formed its independent scheme of Warm Disease. This knowledge in febrile contagious disease is relevant today in providing diverse treatment and prevention for influenza A.

This study was conducted to classify Korean native chicken(KNC) and imported chicken by phenotypic performances and DNA fingerprinting. Two lines, KNC and White Leghorn(WL) , of chicken were maintained in the laboratory of Yeungnam University. Economic traits (body weight, sexual maturity, hen-day egg production, egg weight) and phenotypic characteristics (body-type, head, feather, shank) were checked. The DNA fingerprinting was analyzed for both breeds. The growth rate of the KNC was similar to WLS and sexual maturity of the KNC came later than WL. Hen-day egg production of the KNC was also slightly lower than the WL. The egg weight was about 10g lighter than WL. There was no difference in body weight of female KNC compared to the WL after 28 weeks. The study confirms difference between KNC and WL in DNA fingerprinting as well as its outlook. Thus, we suggest that these should be tested in nationwide districts about chickens known as the KNC using DNA fingerprinting. Then, the confirmed KNC populations should be maintained and used for the genetic improvement. Finally, only confirmed KNC should be in market which induce consumer to seek the KNC by its favorite.

This study was conducted to investigate the effect of dietary bee venom on serum characteristics, antioxidant activity, and hepatic fatty acid composition in broiler chickens. A group of 875 one-day-old feather-sexed male broiler chicks were randomly allocated to five treatments with seven replicates (25 birds/replicate) for three weeks. A corn-soybean meal-based diet was used as the basal diet. Five dietary treatments were compared: 1) basal diet, 2) basal diet containing $10{\mu}g/kg$ of bee venom powder, 3) basal diet containing $50{\mu}g/kg$ of bee venom powder, 4) basal diet containing $100{\mu}g/kg$ of bee venom powder, and 5) basal diet containing $500{\mu}g/kg$ of bee venom powder. At 21 days, one bird per pen was slaughtered by asphyxiation in $CO_2$ gas, and blood was collected to measure serum characteristics and antioxidant activity. In addition, the liver was excised to measure the concentration of malondialdehyde and determine fatty acid composition. Increasing dietary bee venom in the diet failed to affect most serum parameters except for triglyceride and non-esterified fatty acids. Dietary bee venom inclusion quadratically increased the concentration of stearic acid (P<0.05), but decreased palmitoleic acid, oleic acid, linoleic acid, mono-unsaturated fatty acids, and poly-unsaturated fatty acids. Finally, dietary bee venom tended to lower hepatic malondialdehyde contents quadratically (P=0.054). In conclusion, our study revealed that dietary bee venom improved antioxidant capacity and affected fatty acid metabolism in broiler chickens.

In this study, the anatomic characteristics and the contents of nutritional ingredients and minerals of silky fowl and yeonsan ogolgye was investigated. Silky fowl is covered with white silky feather. There is a pinch of vertical white tassel on peak of the head, especially a silky fowl cock. The crown of a silky fowl has a nickname of phoenix crown, the crown of a cock is mostly like a rose, while that of a hen like strawberry or mulberry. The ear of silky fowl is mostly peacock green(Light blue turquoise), bronze for a small part. Peacock green is most common for Silky Fowl with a age of $60{\sim}150$ days, over the age of 150 days, the peacock green will be gradually replaced by purplish red. Beaks are leaden blue, short and stout while the face is smooth and fine. The lower jaw of silky fowl has comparatively long tiny hair, similar to beard. The two legs of silky fowl are covered with a handful of feather, or known as 'Putting on trousers'. Each leg of silky fowl has five talons. The whole skin, eyes, mouth, talons of silky fowl are grey black The bone and marrow of silky fowl are light black the periosteum is black. The whole meat, internal organs and abdominal fat of sillry fowl aye black the heart and leg meat are light black. Silky fowl meat had lower moisture and lipids content, but higher Ash and protein content than meats of yeosan ogolgye and general chickens. For mineral contents of leg muscle and breast muscle, silky fowl had higher contents of phosphorus (P), iron (Fe), potassium (K), zinc (Zn) than those of yeonsan ogolgye, while yeonsan ogolgye had higher contents of calcium (Ca) than that of silky fowl. The contents of iron (Fe) and zinc (Zn) is higher in leg muscle than in breast muscle for the silky fowl and yeonsan ogolgye. Leg muscle of silky fowl contains a lot of iron (Fe), about 4 times as much as that of leg muscle of yeonsan ogolgye. For the silky fowl and the yeonsan ogolgye, leg muscles contains a lot of zinc (Zn), about 5 times, 4 times respectively as much as that of breast muscle.

This study aims to extract manufacturing techniques by analysing metallurgical characteristics of the cast-iron pot from Bubjusa, examining corrosion status and microstructure with a optical microscope, SEM-EDS, micro vickers hardness tester and XRD. The microstructure analysis has presented that ferrite and partial portion of pearlite exist within the corroded outer layer. The analysis of the inner layer revealed that there is pearlite and graphite of feather shape. The one of the middle layer, which is placed between outer and inner layer, showed that corrosion has been heavily developed. Micro vickers hardness values range from 217Hv to 698Hv in constituent layers and such values lie within the ranges of the ancient iron relics. The result of EDS analysis for each microstructure presented that the outer layer has been more decarbonized than the inner layer. XRD analysis of iron corrosion compound revealed that Goethite and Hematite had been produced from the corrosive process of iron. The study concludes that the large iron pot was made by casting technique, and microstructure of inner layer had a gray cast iron. Outer layer has been decarbonized through repetitive process of heating and cooling. This results can be used as fundamental data for comparative study to reveal manufacturing techniques of large cast-iron pot.

These days, the products like Walkman, mobile phone, notebook PC, PDA are moving together with our body, and in the imaginary world like internet, our other self, Avatar is moving in place of our body on the cyber world. These products are related with our human body, and when considering the ones, attached to the human body, and having the meaning of mental combination like these, as the combination of the human and the products, it is necessary to examine these products in approaching them with respect to the combination relation between the human and the products. As a result of examining we can understand that the products, said to combine with the human body, are coming oui steadily. and recently, the inclination on the combination and the movement appears strongly. As this background, there are a breakdown of dichotomy thought, mixed sexual imitation, cyber culture, techno culture. concept of informative nomands, phenomenon which the division of human and machine becomes vague. and the miniaturization of products. imitation of human, phenomenon that the Inclination on the combination with human is more accelerated by networking. These products combine with human body at each wearing type in the various forms. Its functions become multi-layered, and closer to the human body physically. or its communication becomes high·graded and, they have the recombined form through the existing products which the human has And, they communicate each other. have the strong fashionable property, and the characteristics like the imaginary product to imitate the human body and substitute for the human behave.

This thesis looks into the characteristics and compares the clothing styles between the Three Kingdom to the Unified Shilla era. The purpose of this study is to see what common themes exists between the foundation of Korean clothing and how it has evolved and through see to what extent the Chinese influence has been to Korean clothing culture. Also by explaining the originality and creativity of Korean clothing, we will be able to make clear the status of Korean culture. These findings include the following; 1. The Korean strait line Gik-ryong Kyo-im can also be found at the Gochang region in the west. 2. The Ban-ryong-ui, worn by the aristocrats of the Three kingdom and Unified Shilla era, began to appear from the nobles from the Nam-Buk cho(South-north era). This combined with a Bokdu(headwear) became a part of casual dress wear. 3. Go(pants) became a traditional part of clothing for Unified Shilla and the west. 4. Ban-bi and Bae-dang, all forms of Bansu-ui ( short sleeve), came from Chinas Kucha and Hotan and came to Korea. 5. Chinas Pae-baek and Pae-za (Shawl) which is the same as Unified Shillas Peo was also to be found to have come from the west. 6. The way a different color line was added to clothing both can be found in Korean and western clothing. Similarities to material used are; First, expensive wool was used and mostly originated from the west. From far away Rome came the O-saek-gae (Five-color wool). Secondly, Kong-gak me (peacock feather) and Bi-chi mo were all originated from the west. Third, Sil-sil is stated in the Sam-kuk Sa-ki (Three Kingdom records) as being prohibited to be worn by Jin-gol women (Highest nobility during Shilla era) as headwear or comb (pin) or as a comb(pin) for yuk-doo poom ( 6th class nobility) women. Suggesting that it existed and other sources tell us that it came from Tashkent region of Russia and was a jewelry of some sort. From what we have seen above, we can see the similarities between Korean and western clothing cultures and that these interactions not only occurred with China but with many other nations. We can see that our ancestors were creative and original that when importing foreign cultures that they transformed them into a Korean style. That these foreign cultures were transformed into our own style is good evidence to these facts.

Ancient documents, characters, and relics are the utmost important materials when it comes to researching ancient clothing. Of these, the ancient characters explain the contents of the time, which makes it an objective historical record. China has hieroglyphics, such as oracle bone inscription and bronzeware script, which existed in Sang[Eun] Ju era. This character is formed by a simple line and detailed drawing, showing the object or the concrete form and characteristics, so the reader can understand the meaning. Oracle bone inscription and bronzeware script, which are written in pictograph, include contents that help to grasp the original shape and form of ancient official hats. Chinese characters Geon(巾, 건) Byun(㝸, 변) Myun(免, 면) Mo(冒, 모) Ju(冑, 주) and Kwan(冠, 관), which are the names of the official hats, have been researched, and Mi(美, 미) Ryung(令, 령) Wang(王, 왕) and Hwang(皇, 황), which are the characters related to the official hats, have been studied. Geon(巾, 건) switched its form from shape of material around waist to wraping wearer's head. Byun(㝸, 변) is a hat with decoration, and Myun(免, 면) is in form of a helmet with ornaments. Mo(冒, 모) in bone script looks like a hat with decorations on each sides, but in bronzeware script, it is more like a simple round hat Ju(冑, 주) covers one's head and has decorated ornaments, and The Kwan(冠, 관), which is now a common name of official hats, is not shown in oracle bone inscription or bronzeware script, It might have been used later than the other two types of hats. As for the related Chinese characters, Mi(美, 미) is in the shape of a feather decoration, Ryung(令, 령) is similar in shape to the letter 'A', and Wang(王, 왕) is in shape of simple hat from 령 with decorations. Hwang(皇, 황) is like a Wang(王, 왕) hat, but with fancier decorations. Oracle bone inscription and bronzeware script show the original form and shape of ancient hats.

Feral pigeon (Columba livia) has been known as a good indicator for accumulations of chemical pollutants in urban areas. However, it is against the animal rights to kill the indicator species in order to monitor pollutants accumulations in wild birds. Eggs and feathers of birds, therefore, have been used as non-invasive monitoring materials. Even though eggs are a good indicator for accumulations of lipophilic pollutants, but unsuitable for some heavy metals such as lead and cadmium because bird's ovary builds a sort of barrier to inhibit higher accumulations of some heavy metals in the eggs. Therefore, feathers instead of eggs have been used as a non-invasive indicator for accumulations of heavy metals. However, there are few studies of heavy metal accumulations of feral pigeon in Korea. In this study, we characterized the characteristics of heavy metal accumulations of feathers in relation to internal organs (bloods, viscera and bones) in feral pigeons between two sites (Hangang Park representing urban area and Hampyeong Park for rural area). The samples from the Hangang Park showed significantly higher lead (Pb) concentrations in the blood, liver and bone than those from Hampyeong Park. The Pb concentration in the feathers was also significantly higher at Hangang Park than at Hampyeong Park. The analytical result for the breast, wing and tail feathers, and the internal organs (blood, lung, liver, kidney and bone) indicated that the Pb concentrations in the feathers were significantly positively correlated with the levels in the kidney and bone. Overall, feathers of feral pigeon may be candidate for bioindicator to monitor for Pb accumulations in urban areas.
