The Oroqen (鄂伦春) traditional costume refers to what the nomadic Oroqen people used to wear before they settled into fixed communities. With very limited contact with the outside world and with limited resources, the clothing material was virtually entirely animal hide. With settlement, especially after 1996, animal hide clothing has declined among the Oroqen. As an important part of Oroqen tradition and culture, the Oroqen people keep endevoring to promote costume design through competition and exhibitions. Therefore, this paper seeks to present an insightful understanding of Oroqen culture and the formative features of their general clothing. We explored the formative features of Oroqen animal hide clothing based on an analysis of actual artifacts and literature. As a result, the characteristics of Oroqen hide clothing were found in five types - coats, trousers, hats, shoes, gloves. For the decoration, embroidery and applique were their way of decoration, and Mother Nature was their source of pattern design.

Ammonia and/or sulphur dioxide treated and untreated wheat leaf sheaths were compared for cell wall digestion by incubation with rumen liquor for 24 and 48 hours. Scanning electron microscope (SEM) was used to study the relative rate and extent of cell wall digestion. Treated wheat straw leaf sheaths were distorted, with more distortion observed in ammonia and sulphur dioxide combined treatment than any other treatment. Rumen liquor digestion for 24 hours of untreated leaf sheath showed disrupted phloem, partially ruptured parenchyma and vascular tissues and further partially distorted inner bundle sheaths and vascular bundle after 48 hours incubation. Sulphurated leaf sheaths showed extensive degraded parenchyma and sclerenchyma material in 24 hours incubation, however, all tissues were irregulary shaped in 48 hours incubation. In ammoniation, epidermal cell walls and small vascular bundles began to disintegrate by 24 hours incubation, extensively changed structure and degraded epidermal tissue by 48 hours incubation. Combination treatment of leaf sheaths degraded all cell walls of parenchyma, phloem and vascular bundle by 24 hours incubation, however, structures only of inner bundles sheath with extended land, sclerenchyma and cutinized epidermal cell walls remained.

An empirical review on silk fabrics of the Chosen period showed that they varied in kind and design according to their uses. Thus the purpose of this study is to classify the fabrics into temple and excavated fabrics according to their uses and collected places and then to examine characteristics of each type. Concerning fabrics collected in temples. satin was most used, followed by twill, tabby, multiply, leno and gauze and clossing fabrics in order. Tabby and silk fabrics used Ju(紬) as their main material. Cho( ) was much more used in fabrics collected in temples than in excavated ones. This indicate that Cho( ), more luxurious than Ju(紬), had divine applications such as covering Buddha s bones of temples. Brilliant, colorful multiply fabrics using goldern and color threads had high effects of ornamenting altar covers, umbrellas, surplices and palanquins. Fabrics held in temples adapted composite designs, in which more than two shapes were used, rather than single ones. Single designs employed plant shapes in most cases. followed by treasures pattern, geometrical, cloud and animal shapes in order. Most composite designs used a combination of animal and plant shapes, followed by plant and geometry, treasures pattern and plant, cloud and animal, and animal, treasures pattern and plant in order. Few excavated fabrics used animal designs while fabrics collected in temples were often designed with shapes of propitious animals such as dragon. Treasures pattern. representing a good omen of Buddhism, was often used sing1y or sometimes compositely with another design.nother design.

A rapid and simple analytical method for L-carnitine was developed for infant and toddler formulas by liquid chromatography tandem mass spectrometry (LC-MS/MS). A 0.3 g of infant formula and toddler formula sample was mixed in a 50 mL conical tube with 9 mL water and 1 mL 0.1 M hydrochloric acid (HCl) to chemical extraction. Then, chloroform was used for removing a lipid fraction. After centrifuged, L-carnitine was separated and quantified using LC-MS/MS with electrospray ionization (ESI) mode. The precursor ion for L-carnitine was m/z 162, and product ions were m/z 103 (quantitative) and m/z 85 (qualitative), respectively. The results for spiked recovery test were in the range of 93.18-95.64% and the result for certified reference material (SRM 1849a) was within the range of the certificated values. This method could be implemented in many laboratories that require time and labor saving.

Objective: In this study effects of three types of beddings on broiler leg health and bone biomechanics were evaluated. Methods: A total of 504 male chicks (Ross 308) were randomly placed on three beddings (4 replicates/group; 42 birds/pen), zeolite-added litter (ZL), plastic-grid flooring (PF), and wood shavings (WS). On day 42, chickens were weighed, slaughtered, and samples (bone, muscle, and drumstick) were collected. Bones were subjected to leg health tests, morphometric measurements, biomechanical testing, and ash analysis. Results: Broilers in PF and WS groups showed higher live weight than the ZL group (p<0.001), and the incidence of tibial dyschondroplasia (TD) and varus valgus deformity due to distal bending was significantly higher in PF (p<0.001). Multinomial logistic regression showed that bedding has a significant (p = 0.038) contribution toward the development of TD. Tibial strength (p = 0.040), drumstick width (p = 0.001), and total femur and epiphyseal ash contents (p = 0.044, 0.016) were higher in the ZL group. Chicken live weight was correlated with tibial length and weight (r = 0.762, 0.725). Conclusion: Flooring and the type of bedding material directly affect broiler bone length, strength and leg health. Plastic bedding improves the slaughter weight of chickens on the expense of leg deformities, and zeolite litter improves leg health and bone strength.

We obtained four zoeal stages of Harrovia japonica from laboratory-hatched material. They are described, illustrated in detail, and compared with those of other known species in the family Pilumnidae. The general zoeal morphology of H. japonica coincides well with those of other known species of the Eumedoninae (excluding Echinoecus pentagonus) and Pilumnus minutus of the Pilumninae. In order to facilitate the study of planktoncollected material, we provide a key for the identification of seven known zoeae of the Eumedoninae from the IndoPacific.

This study was performed to establish an effective extraction method of pig placenta extract that could be used for a putative functional food supplement with immunomodulatory effects. In the present study, we used different temperatures (4, 37, 60, 80, and $100^{\circ}C$) and different solvents (chloroform, NaOH, and phosphate buffered saline [PBS]) to extract the pig placenta. Among the different placenta extracts yielded by the different extraction methods, placenta extract (PE) in PBS at $80^{\circ}C$ for 30 min (referred to as PE-PBS80) showed a significant increase of nitric oxide production of up to 22.97 ${\mu}M/10^5$ cells at a 1 mg/mL dose (p<0.05 ) in J774A.1 cells than other extracts and control tested. Using PE-PBS80, further animal challenges were performed to identify the immune-enhanced effects. As a result, orally administered PE-PBS80 showed a significant increase in blood T and B cell activities and immunoglobulin (IgG and IgM) production. IgG and IgM levels increased to 41.53 mg/mL at a 20 mg dose on day 7 and to 27.38 mg/mL at a 10 mg dose on day 14, respectively (p<0.05). Furthermore, PE-PBS80 was also able to significantly enhance the immune modulator cytokine levels (p<0.05) compared to the control and vehicle treatments. Among the evaluated cytokines, the tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$) level increased to 28.89 pg/mL at extract doses of 20 and 50 mg, the interleukin-$1{\beta}$ (IL-$1{\beta}$) level increased to 21.52 pg/mL at extract doses of 10, 20, 50 and 75 mg and the interferon (IFN)-${\gamma}$ level increased to 18.24 pg/mL at extract doses of 10, 20, and 50 mg. Therefore, this study presents an effective method for extracting pig placenta extracts and also demonstrates that pig placenta extracts had significant immunomodulatory effects not only at the cellular level but also in a mouse model, suggesting that this material could be used as an excellent candidate functional food supplement.

Objective: This study was conducted to evaluate the physicochemical properties and changes in moisture concentrations of bedding materials under the conditions of rearing Korean Hanwoo cows. Methods: Two experiments were conducted to investigate the physicochemical characteristics (Exp. I) and usefulness as beddings for rearing cattle (Exp. II) by the type of beddings such as sawdust (SD), wood shavings (WS) and sawdust+wood shavings (S+W; 1:1 in volume), and the species of pine trees from different countries of origins (China, Pinus armandii, AR; Vietnam, Pinus kesiya, KE; USA, Pinus rigida, RI). Results: In Exp. I, SD-AR showed the largest proportion (78.3%) of fine particles (250 ㎛+below 250 ㎛) and the highest bulk density (208 kg/㎥) among treatments (p<0.05). The water absorption capacity at 24 h of both S+W-RI (713%) and -KE (701%) was the highest among treatments (p<0.05) and higher than those of SD or WS alone within each species of pine tree (p<0.05). Moisture evaporation rates (%) at 12 h were ranged from 52.3 to 60.8 for SD, 69.9 to 74.4 for WS, and 72.3 to 73.5 for S+W. Total amounts (mg/㎡) of ammonia emissions were the lowest (p<0.05) in KE species among the pine species within each type of bedding material, having higher ability of ammonia absorption. In Exp II, KE species in both side A and B had lower moisture concentrations (%) than other species. Regardless of types of beddings except SD-AR, moisture concentrations of beddings within a pen were higher (p<0.01) at side A than B. Conclusion: The KE species has better physical characteristics than other beddings and more useful for rearing Hanwoo cattle than other beddings, probably caused by the differences in the method and degree of wood processing rather than the species.
