Until now, there are no scientific studies for Dongkyung-i(DKI) dog, which is recently called as Deng-Kyun. This study is aimed to investigate the characteristics of DKI. According to visiting studies, DKI is an active, live and muscular dog. The dog is willing to announce the approach of strangers friendly. As the results of morphological studies, DKI is medium sized and the average weight is 22.6 kg. Its coat has mainly yellowish brown color and short hair. Morphologically, the dog showed vestigial tail and muscular and sturdy pelvic limbs. As the results of radiological studies, DKI is characterized as the absence of coccygeal vertebrae or the coccygeal agenesis. We concluded that DKI may be a Korean native canine breed characterized as short or non-tail dog. Also, we suggested that this characteristic dog is valuable to develop as a Korean native breed.

The purpose of this study was to investigate the contamination rates of Keratinophilic fungi in soils In Chonju. From september to November 1986, 98 soil samples were collected at the school and children's play ground, dog barn, pig barn, cow barn, horse barn and fowl barn( total 33 sites ). The samples were collected at the different depths(0～2cm, 30cm, 50cm ) in each of the sites, respectively. Each sample was cultured at 25$^{\circ}C$ according to Modified hair baiting method by using horse mane hair as a bait. The results obtained were summerized as follows ; 1. Eighty one of the 98 soil samples were found to be positive for Keratinophilic fungi. 2. In the examination of keratinophilic fungi in 98 soil samples, the organisms isolated weie as follows; Microsporum gypseum 20, Trichophyton ajelloi 15, Chrysosporium tropicum 40, C. Keratinophilum 24, C. tuberculatum 6 and Chrysosporium spp. like organism 4 strains. 3. The positive rates of keratinophilic fungi in each of the depths were 87.9%(29/33) in surface layer, 90.9%(30/33) in middle layer and 68.8％(22/32) in deep layer. 4. The positive rates of Keratinophilic fungi in each of the sites were 100%(3/3) in horse barn 91.7％ (l1/12) in dog barn, 88.9%(16/18) in pig barn, 86.7%(13/15) in cow barn, 76.2%(16/21) in fowl barn and 75.9%(22/29) in school and children's play ground. 5. The isolation rates of M. gypseum, Pathogenic fungi for human and animals, were as follows ; 58.3％ in dog barn(surface layers 100％, middle layers 50％, deep layers 25％) and 16.7％ in pig barn(surface 33.3％, middle 16.7%, deep 0％). In the cow barn, the isolation rates were 13.3%(surface 40.0％, middle 0%, deep 0％) and 10% in horse barn(surface l00％, middle 100%, depp 100%).

Canine cataract is developed with aging and can cause the blindness or surgical treatment if not treated timely. The first observation must be made by pet owners but they do not have proper equipment and knowledge to see the abnormalities. In this paper, we propose an intelligent image processing method to extract canine cataract suspicious object from non-professional equipment such as ordinary digital camera and cellular phone photographs so that even casual owners of pet dog can make a pre-diagnosis of such a surgery-needed disease as soon as possible. The experiment shows that the proposed method is successful in most cases except the dog has similar colored hair to the color of cataract.

The aim of this study is to investigate the expenditure items and expenses for companion dogs and the appropriate considerations when choosing companion dog food for consumers who purchase dog food through the internet. The survey subjects consisted of 39 males (6.8%) and 532 females (93.2%), and it was found that most women purchase dog food through the internet. According to the age of dog owner, 184 (32.2%) were in their 20s and 241 (42.2%) in their 30s and 146 (25.6%) in their 40s or older. According to the age of the dogs, 200 (35%) were under 3 years old, 202 (35.4%) over 8 years old, and 169 (29.6%) were between 4 and 7 years old. The most preferred ingredient was chicken, regardless of dogs' owner or the dogs' age. Spending less than 100,000 won was most frequency reported, regardless of dog owner and the age of the dog, and major dog food was reported to be purchased in the order of online shopping malls and animal hospitals. In order to improve health function, it was determined that improvement of skin and hair is the most important, and next, was improvement of tooth bone formation and digestibility. When choosing food for companion dogs, nutritional composition of all the products was the most important consideration, followed by brand products with recognition, color, smell, shape, functional improvement products, and price of the products. Therefore, when developing a new product for companion dog food, consideration must be given not only to the nutritional components of all products, but also the brands, color, odor, shape, nutritional balance, functional improvement and price.

A clinical case of CheMletietlo infestation on a dog born and raised in Korea is reported. A three-year old female Whippet was hospitalized due to a multiple fracture and displacement of the left scapula caused by a recent car accident The mite infestation was not noticed at the time of hospitalization. The dog underwent multiple operations involving internal fixation of the fractured scapula with wire and a plate, followed by extensive chemotherapy with antibiotics and prednisolone. After two months of hospitalization. a pruritic dermatitis near the left scapula developed. Multiple white dandruff-like ilakes were seen on the hair coat. especially over the dorsal spine and neck, and the dog expressed increased pruritus by frequently licking and scratching the affected areas. Local dense accumulations of skin debris that became crusty were also observed. Microscopic examination or a skin scraping revealed a heavy infestation of cheyletiella vnsfuri. as idrntified by the prrsrnce of holes of the palpi and the heart-shaped sensory organ on menu I. Immnosuppression elicited by the extensive administration of prednisolone was suspected for the initiation of the generalized mite infestation.

Two-month old male Shih Tzu weighing 2.1 kg was presented with alopecia in black-haired areas of the skin. The hair loss had been present since five weeks of age. There was no history of pruritus on any part of the body. No other symptoms had been recognized. Physical examination found no abnormalities other than hair loss. Skin examination showed marked alopecia of black-haired area of the body. The white areas appeared to have hair growth of normal density and texture. Affected pigmented areas showed no evidence of skin lesions. Skin scraping and fungal culture were negative. Microscopic examination of plucked black hairs showed marked pigment clumping in the remnants of the follicles and were mainly in telogen phase. But white hairs were normal in various stages of hair growth. The diagnosis of black hair follicular dysplasia was made based on the history, alopecia of the pigmented areas, the confinement of abnormalities to dark areas, and the normal unpigmented areas.

The indoor environment is an important source of exposure to various aeroallergens and pathogenic microorganism. It has been shown that exposure to aeroallergens enhances the risk of indoor inhabitants developing asthma. Since the skin prick test, a typical clinical method for identification of subjects positive to allergens, can rarely cause fatal or non-fatal reactions in susceptible persons, an in vitro assay such as ELISA using serum has been considered for testing positivity against various allergens. We evaluated the validity of a serum ELISA kit for screening positive subjects to major aeroallergens including Dermatophagoides farinae, Dermatophagoides pteronyssinus, cockroach, Alternaria, Cladosporium, Aspergillus, Penicillium, dog hair, cat fur, mugwort, and ragweed. The ELISA results were compared with the skin prick test results, and sensitivity, specificity, and overall accuracy were calculated to each allergen. Higher sensitivities were obtained from D. farinae, (77.8%) and D. pteronyssinus (69.2%), but sensitivities to Aspergillus, Penicillium, dog hair, cat fur, and ragweed were very low down to 0%. Specificity ranged from 88.7% (cat fur) to 100% (mugwort and ragweed). Overall the accuracy of the serum ELISA kit was relatively high, in that the lowest was 85.1% for cat fur and the highest was 98.6% for Alternaria, Cladosporium, and ragweed. Considering specificity and overall accuracy for the serum ELISA kit, it may be considered reliable. However, when the kit is used for screening purpose, positivity to aeroallergens should be carefully determined since sensitivity for the kit is low.

Objectives: This study attempted to investigate the allergic histories and the distribution of offending allergens in the general public and further to help their diagnosis and treatment with Oriental Medicine. Methods: Allergic skin tests (AST) were performed and allergic histories were taken of 359 members of the general public who visited the International Exhibition on Oriental Medicine from Sept. 1 to Sept. 5, 2000. The allergen reagents for AST were three (House dust, D. farinae, Dog hair) and the control reagent was histamine solution. Results: 1.50.1 % of the subjects (n=359) were positive to AST. The ratio between males' positivity and females' was 1.06：1. 2. The younger the subjects were, the higher the positivity was. 3. The positive subjects' (n=180) positivity to three allergens was as follows: D. farinae 98.9%, House dust 30.0%, Dog hair 1.7%. 4. The younger the positive subjects were, the higher the positivity to House dust was. In contrast, the positivity to D. farinae was high in all age groups. 5.71.1 % of the positive subjects reacted positively to monotype allergen and 28.9% reacted positively to multiple allergens (2.46：1). The most common monotype allergen was D. farinae (98.4%) and the most common combination of multiple allergens was House dust and D. farinae (94.2%). 6.52.8% of the positive subjects (n=180) and 51.4% of the negative subjects (n=179) represented the history of allergic diseases. There was no relationship between allergic skin test and allergic diseases. Conclusion: To help in diagnosis and treatment with oriental medicine, research to analyze the relationship between allergic skin test and allergic diseases should be continued on the basis of Oriental medical theories.
