The purpose of this research is to find out the role of shaman's costume in Yakut Yukachir Goldi. The results are as follows: 1. Yakut shaman's costumes are decorated by their worship symbols made from metals-wild ducks crucian carps diving beetles and fishes. They believe that these costumes help shamans to travel the heaven underwater or underground systems to collect wanted infor-mation transforming them into the shape of decorated animals. 2. Yukachir shaman's costumes are decorated by symbolized cross medals in the shape of birds and human designed backbone which give shamans much power and many different kinds of medals and tassels representing all sorts and conditions of shaman's power. They consider their cstumes as feather and believe they give them new power and make them to fly anywhere they want. 3. Goldi shaman's costumes have paintings of animal guradians-leopards tigers bears birds snakes lizards and so on. Birds represents freedom of the spirit and eternity. snakes represents rebirth and immorality and lizards represents the trees of underground the earth and the lifetrees of the heaven. Shamans ascend through th holy tree to th heaven and to the world of underground in a comatose condition. Shaman costume itself plays the role of the spiritual safeguard. Wearing their costume shaman get all animal's supernatural authority and power. This makes the shaman to contact with the spirit and to travel the heaven and the under-ground world.

We investigated changes of immunoglobulin G (IgG) concentrations by heating and drying condition. Also it is performed to group for commercial product by promoting of IgG preservation and reducing of protein denaturation. The result was that content of IgG in colostrum was higher than normal milk. Especially, IgG content of colostrum within 12 hrs after parturition was over 44.67mg/ml and it is 60 times of normal milk. IgG contents was reduced rapidly according as passage of the time. IgG content of the sample heating at 30min at 65$^{\circ}C$ was still a little higher that heating for 10sec at 72$^{\circ}C$. IgG denaturation of heat treatment at 100$^{\circ}C$ for 10sec was lower than at 85$^{\circ}C$ for 30min. We investigated the changes of IgG concentrations of kinds of market milk different with heating processing. This result showed that IgG denaturation ratio by ultra high temperature pasteurization (UHT) was higher than long time low temperature pasteurization (LTLT). On the other hands, IgG content by spray drying was 14.5mg/g and freezing drying was 10.8mg/g. It showed that denaturation of protein content by freezing drying was more than spray drying.

Recently, clinical efficacies of the intraoral balancing appliance therapy have been reported by several researchers, and it has been found that there are various kinds of diseases that can be effectively applied. However, studies on cerebrovascular disease, one of the main diseases with a high mortality rate, are still poorly reported, and studies of temporomandibular joint disorder (TMD)-induced changes in brain function suggest that cerebrovascular disease is more appropriate as an adaptive disorder of the temporomandibular joint (TMJ) balancing device. In the developed countries, the importance of research on the structure and function of the brain has been recognized and spurred on the related research. In Korea, the research on brain function and cognitive disorders should have promoted more massively. In order to regain its former reputation in the Korean medicine in the field of cerebrovascular disease, it should be spurred on basic research and clinical case studies. In addition, extensive and in-depth studies including animal studies are needed to establish the basis of underlying mechanisms of the TMJ balancing therapies.

Upon gene inactivation in animal models, the zebrafish (Danio rerio) has become a useful model organism for many reasons, including the fact that it is amenable to various forms of genetic manipulation. Genome editing is a type of genetic engineering in which DNA is inserted, deleted, modified, or replaced in the genome of a living organism. Mainly, CRISPR (clustered regularly interspaced short palindromic repeats) Cas9 (CRISPR-associated protein 9) is a technology that enables geneticists to edit parts of the genome. In this study, we utilized this technology to generate an mmp15b mutant by using zebrafish as an animal model. MMP15 is the membrane-type MMP (MT-MMP) which is a recently identified matrix metalloproteinase (MMP) capable of degrading all kinds of extracellular matrix proteins as well as numerous bioactive molecules. Although the newly-established mmp15b zebrafish mutant didn't exhibit morphological phenotypes in the developing embryos, it might be further utilized to understand the role of MMP15 in liver-related diseases, such as liver fibrosis, and associated pathogeneses in humans.

Effective Microorganisms (EM), a fermented medium developed by Professor Higa at the University of the Ryukyus, is a mixed culture containing dozens of microorganisms which are beneficial to nature including people, animals, plants and many microbial species in environment. EM is known to contain more than 80 kinds of anaerobic or aerobic microbes including photosynthetic bacteria, lactic acid bacteria, yeast, actinomycetes, fungi and so on, with yeast, lactic acid bacteria and photosynthetic bacteria as the main species of EM. Antioxidant effect generated by the concert of complex coexistence and coprosperity among these microbes is considered to be the main source of EM benefits. Currently, EM is earning an increasing attention with applications in agriculture, forestry, animal husbandry, fisheries, environment and medicine among others. At the same time, however, a quantitative interpretation of EM system based on a mixed culture model needs efforts from biochemical engineers for efficient production and further promotion of EM. In this paper, we describe the functions of major microbes in EM and current researches and applications of EM in agriculture, forestry, animal husbandry, fisheries, environment and medicine.

The ultrastrucures of Xenopus otic vesicle from normal embryo (st. 43) and induced otic vesicle from animal cap assay with Activin A were compared. Activin A was applied to the presumptive ectoderm at various concentrations for three days at $20^{\circ}C$. The results were almost identical to the reference studies, but it was found that the otic vesicle was induced at the concentration of 10 ng/ml in to)v rate. This otic vesicle may be secondarily induced by the neural tissue showed commonly at the concentration of 10 ng/ml. Otoliths were observed as three or four-axis crystaline bodies in the lumen of otic vesicle. In electron micrograph of the normal embryo, two kinds of microvilli were observed on the apical position of hair cells. One was small and common, the other was large-sized and sparsely distributed. In both cell of otic vesicle, mitochondria, golgi apparatus and multivesicular body were rich, so, they showed a lot of similarities in ultrastructure. However, the otolith was not found and microvilli were overexpressed in the otic vesicle induced by Activin A.

This study was conducted to determine the effects of microperforated film on the quality and shelf-life improvements of pork bellies during cold storage. Samples were stored for 14 days at 0$\pm$1$^{\circ}C$ and 55$\pm$10% r.h.. The packaging treatments were the unpackaged sample as control, the wrapped sampled with microperforated polypropylene film(MPF) and unperforated PP film(PPF), respectively. After 10 days, the counts of all kinds of microorganisms investigated tended to be the lowest in the control samples, and followed by MPF and PPF. The 'a' value for PPF was significantly lower than the values for control and MPF at 14 day. The 'L' values for MPF measured after 10 days were significantly lower than those of PPF and higher than those for control. After 4 days of storage, the 'b' values for PPF showed significantly lower than those of MPF. As storage time elapsed, percent weight loss was the highest in the control samples followed by those from MPF and PPF. Sensory analyses showed that MPF samples tended to be evaluated higher in all parameters than the control and PPF samples after 7 days. It is concluded that microperforated film wrapping can be used efficiently for maintaining the quality of fresh pork bellies during cold storage and retail display.

This study aimed to develop an experimental animal model of duodenal ulcer for application to nutrition, and to verify the nutritional characteristics. The 7 different doses and 8 different injections of cysteamine and 2 kinds of diets with different casein levels(10%, 20%) were tested to examine the incidence and the process of duodenal ulcer in female Sprague-Dawley rats. The result showed that the duodenal ulcer was induced when rats fed 10% casein diet(for 9 days) were injected 6 times with 13mg/100g BW cysteamine. The first injection was conducted after 24 hours of fasting, followed by the 2nd shot after 3 hours. The following shots were repeated every 3 day(4th and 7th days). Duodenal ulcer was observed 3 days after the last injection by optical microscope and the naked eye. The characteristics of nitrogen bioavailability of duodenal ulcer model were as followings : 1) gastric emptying rate was faster, 2) trypsin activity at duodenum was higher, 3) total protein concentration at serum and nitrogen retention rate were lower than the control.

This study was carried out to find deodorization management method of the efflux from swine slurry treated by thermophilic aerobic oxidation reactor. Three kinds of deodorization methods in Lab-scale reactors, were used in this experiment; No treatment, air injection treatment(50$m\ell$ air/min. $\ell$) and inoculumn of photrophic bacteria treatement(108 cell(Most probable number, MPN)/$m\ell$). The concentration of volatile fatty acids(VFAs), hydrogen sulfide(H2S), and ammonia(NH3) were analyzed during the treatment period(50 days). The major results obtained as follows. 1. Air injection method to efflux showed very high removal effect on malodorants such as VFAs, hydrogen sulfide(H2B). But ammonia(NH3) was emitted to much. 2. PTB inoculum method was also effective in removal of malodorants, VFAs, Hydrogen sulfide(H2S), when it was applied to the efflux. 3. We found that the concentrations of malodorants, VFAs, H2S, NH3 had some relatinships with the pH, ORP, BOD in the efflux.

Two cats were obtained from a cat kennel. Over the previous 7 days, the cats had shown cough, anorexia, depression and nasal discharge. In this study, the consensus PCR was able to detect successfully Mycoplasma species in nasal swab samples of the cats. To identify feline mycoplasma species from the lung tissue of the cats with pneumonia, Mycoplasma species-specific PCR reactions were conducted. As the results, we could identify M. felis by the positive amplified DNAs. On the other hand, we could not detect any positive reactions with the PCR reaction for M. arginini, M. canis, M. edwardii, M. cynos, M. gateae, M. maculosum, M. molared, M. opalescens, M. spumans and Mycoplasma HRC-689. In conclusion, we detected M. felis from the kenneled cats with pneumonia. We suggested that this consensus PCR would be useful and effective for monitoring Mycoplasma species in various kinds of animals including cats. The application of preceding consensus PCR before the species-specific PCRs may be the most recommended strategy for the identification of Mycoplasma spp.
