  • Due to the complex environment in the ground, most of excavated costumes undergo deterioration and color change. To reduce the extent and intensity of the staining and to recover the original color or gray fabrics of excavated costumes, bleaching would be required. Excavated historical costumes are very delicate in nature, therefore, special care is needed in bleaching process. Several bleaching agents were selected and applied to the control cotton fabric and pre-deteriorated cotton fabrics to examine the change of color and physical properties after bleaching. A dual bleaching using hydrogen peroxide and sodiumborohydride showed the superior bleaching effect to the other bleaching agents. The strength of pre-deteriorated fabrics slightly increased after dual bleaching. The six historical costumes which belonged to General Duk-Ryung Kim's nephew's wife were dual bleached. They became remarkably cleaned and brightened. The treatments improved the appearance of costumes. By microscopic investigation, it is found that costumes did not show the damage after treatment. In conclusion, it is possible to bleach historical textiles without damage using appropriate bleaching agents like hydrogen peroxide and sodiumborohydride.

  • This study was performed to determine the quality characteristics of Jeungpyun with the addition of soy yogurt (0%,3%, 6%, 9%, 12%). The proximate composition analysis showed that moisture contents of Jeungpyun were 49.87${\sim}$51.60%, and crush protein, lipid and ash contents were 2.58%, 0.21${\sim}$0.33% and 0.58${\sim}$1.05%, respectively. The pH ofJeungpyun was higher as the additive increased. Volume and symmetry index were higher as the additive increased, but uniformity index was no significant difference. L value and a value were the lowest in control group and increased with soy yogurt addition, while b value was decreased as amount of soy yogurt. Hardness, cohesiveness, gumminess were the highest in 9% group, springiness was the lowest in 9% group. In surface structure of Jeungpyun observed by SEM, cell size was the smallest and the cell uniformity was most regular in 12% group. According to sensory evaluation, appearance, taste and overall acceptance were highest in Jeungpyun with 9% soy yogurt. Therefore, Jeungpyun containing 9% soy yogurt was most preferable.

  • The quality properties of Gouda cheese supplemented with Korean traditional Yakju (Acanthopanax senticosus or Pueraria thunbergiana wines) were investigated. Yakju was added in the process of Gouda cheese preparation, and proximate composition, lactic acid bacterial population, pH, water-soluble nitrogen, sensory characteristics and proteolysis were determined. The electrophoretic patterns of cheese proteins, the target functional components and thiobarbituric acid values of the cheeses also were analyzed. The sensory characteristics including appearance of the cheeses were not affected by supplementing Yakju. Significantly higher amounts of crude ash, minerals and polyphenols were observed in the cheese supplemented with Yakju compared to the control cheese. The results suggest that the Gouda cheese prepared with Yankju has functional and additional nutrient values without changing cheese characteristics.

  • Among the food constituents, proteins differ in coagulation properties as compared to other constituents in food system. Especially milk protein coagulate through different pathways thus this coagulability can be used for manufacture of various dairy products or as a determinant of dairy product analysis. These milk coagulation methods include organic solvent, isoelectric point, trichloroacetic acid, Ca-sensitive casein, heavy metal ion and rennet coagulation. The coagulation experiment was performed using above parameters at $0^{\circ}C$ and $25^{\circ}C$ to find the dehydration conditions before coagulating for precheese powder making. After different chemical treatments, there was no coagulation at $0^{\circ}C$ rather at $25^{\circ}C$ whatever the mode of coagulation methods was. The appearance of precipitate with coagulation methods was quite different from above mentioned methods of coagulation illustrated by scanning electron microscope. These powders were used for fabrication of camembert cheese by renneting coagulation at $0^{\circ}C$, showing the possibility of cheese materials and of food additives for fabrication of products.

  • Variations in the definition of poultry meat quality exist because the quality traits are not solely based on intrinsic and extrinsic factors but also consumers' preference. Appearance quality traits (AQT), eating quality traits (EQT), and reliance quality traits (RQT) are the major factors focused by the consumer before buying good quality of poultry meat. AQT and EQT of poultry meat are controlled by physical and biochemical characteristics of muscle fibers which can be categorized into a total number of fibers (TNF), cross-sectional area of fibers (CSAF), and fiber type composition (FTC). In poultry meat, it has been shown that muscle fiber properties play a key role in meat quality because numerous studies have reported the relationships between quality traits and fiber characteristics. Despite intensive research has been carried out to manipulate the muscle fiber to improve poultry meat quality, demand in a rapid growth of poultry muscle has correlated to the deterioration in the meat quality. The present paper reviews the definition of poultry meat quality, meat quality traits, and variations of meat quality. Also, this review presents recent knowledge underlying the relationship between poultry meat quality traits and muscle fiber characteristics.

  • Mies van der Rohe is still known as the architect whose influence is the largest among modem architects. As his work is typical of modern architecture, the architecture of Mies shows an interest in materials and techniques, even though It established the new architectural world by glass and iron, and only transparency is emphasized with glass. So it is blame for the loss of peculiarity a result of thinking In the way of sachlich with expression and structure of material and hierarchical relation. Vincent Scully has insist on that an appearance of modem architecture be occur not by simply a technical request of a technician but by reflection of the times and times' spirit. In this means, the works of Mies is the trial to express the new times' spirit that the new times order and an understanding of material properties about glass with new material of modern. For that, this study tries to consider that Mies'work is the new trial through reflection of material to express about the bstraction beyond the limit of sachlich expression, on the point of expresslonal characteristics of material shown in plan of the Barcelona Pavilion and skyscraper and on the basis of the theory of Gottfried Semper and Karl Boetticher that architectural surface Is a medium which can define space and also express mass.

  • This study was carried out to examine the actual using condition of Yogawear and consumer's preference of Yogawear with traditional pattern. Yogawear can be developed as a cultural fashion item, because Yoga is getting universal interest with "Wellbeing Trend". A survey with 34 questionnaires was made by 305 consumers who had ever experienced Yoga from July to August, 2006. The results are as follows: 1. Most of objects were female(94%). Those who are in their twenties accounted for 50%, and those who take Yoga practice time less than 1 year accounted 63%, and those who take Yoga practice time less than 1 hour in a week accounted 46%. 2. Respondents who have Yogawear accounted 32% and they bought it in a online-shopping mall(48%), department store(16%) and discount store(11%). 3. Only 31% of respondents were satisfied of their Yogawear but they weren't satisfied about Yogawear Design, fabric and color. 4. Most preferred Yogawear style was pastel colored 'shirt & Pants' style with long sleeve using cotton fabric. 5. They liked much more modern Yogawear having korean image than completely korean style Yogawear or modern style Yogawear. 6.The benefits of Yogawear were 3 dimension: appearance, easy management, physical properties.

  • As the demand for petroleum resources increases, and oilfields on lands and in shallow-sea become exhausted, the areas for oil production are expanding to the deep sea and therefore technologies for flow assurance are coming into the highlight. In low temperature environment such as the deep sea, wax is accumulated and prevents stable oil production. Therefore, the development of flow assurance technologies is required. Wax is precipitated in crystalline form when the oil temperature decreases below the wax appearance temperature; it then accumulates on the inner walls of pipelines causing blockages. In particular, in subsea pipelines, which have a large surface contact area with the surrounding seawater, wax deposition problems are frequent. The internal tubular coating can effectively reduce wax deposition without pausing oil production when the coating is appropriately designed. This study carried out wax deposition tests on a number of internal tubular coatings under single flow conditions. The results were analyzed for the effects that the physical properties of the coatings had on wax deposition.

  • Wolfiporia cocos is a well-known traditional medicine in China, Japan, Korea, and other Asian countries owing to its numerous therapeutic properties. With the aim to determine the morphology and genetic characteristics of W. cocosten strains of W. cocos were cultivated in vitro, and subsequently, rapid amplification of polymorphic DNA was performed. To the best of our knowledge, this is the first study to examine the morphology of fruit bodies of W. cocos in Korea. W. cocos were cultured on PDA agar at different temperatures (12, 16, 20, 24, and $28^{\circ}C$) under 12-hour light (600 Lux) / 12-hour dark photoperiod condition for 1 month. Appearance of fruit body was the highest at $28^{\circ}C$ condition in all the strains investigated. Honeycomb-like structure on sclerotia was observed in Andong 01, Andong 02, Andong 03, KFRI 1104, KFRI 1105, KFRI 1106, KFRI 1107, KFRI 1108, and ASI 13007 strains of. The KFRI 1103 strain formed cosmos petal-like structure on sclerotia. The average size of basidiospores was recorded as $7.55{\mu}m$ in height and $3.35{\mu}$ in width.
