  • Deer can be one of the susceptible animals to bovine infectious diseases, and thus, may play a role either as a reservoir or amplifier host for spreading the diseases to other species such as cattle and goat. This study was conducted to determine the serum antibodies to bacterial infectious diseases for brucellosis, tuberculosis (TB), paratuberculosis (Johne's disease) in deer. Serum samples were randomly collected from 78 deer from 31 farms at Jeonbuk province, and 7 wild water deer from Jeonbuk wild animal treatment center during 2005 to 2007, respectively. Four farm deer (5.1%) showed antibodies to tuberculosis using Antigen Rapid Bovine TB Ab Test Kit. One elk (1.3%) and one wild water deer had antibodies for paratuberculosis. Antibody against Brucellosis was not detected in tube agglutination test (TAT) and enzyme-linked immunosorbent assay (ELISA). These data suggest that caution should be applied to inspection of velvet, deer blood and meat for human consumption from deer because of zoonotic bacterial diseases in deer. In addition, farmed deer can be a transmissible host for zoonotic disease to diary or raising farm.

  • This paper contains the implementation and performance evaluation results of a system that collects environmental data at the time when the wild animal intrusion occurred at farms and then predicts future wild animal intrusions through a machine learning-based Vector Autoregression(VAR) model. To collect the data for intrusion prediction, an IoT-based hardware prototype was developed, which was installed on a small farm located near the school and simulated over a long period to generate intrusion events. The intrusion prediction service based on the implemented VAR model provides the date and time when intrusion is likely to occur over the next 30 days. In addition, the proposed system includes the function of providing real-time notifications to the farmers mobile device when wild animals intrusion occurs in the farm, and performance evaluation was conducted to confirm that the average response time was 7.89 seconds.

  • The purpose of this study is to propose the angle-limit of the escape ramp by analyzing the frog behavior characteristics according to the inclination angle of the waterway escape ramp installed in the concrete U-bench plume pipe channel. Forthe experiment, an escape test device was manufactured with the same shape and number of materials applied in the field. And Rana coreana living in paddy wetlands were sel selected. The main behaviors of frogs on the slope were 'jumping', 'crawling' and 'slipping', and afterrecording the behavioralresults according to the inclination angle, statistical analysis was conducted using the chi-square test method. As a result of the analysis, there was no statistically significant difference between 30° and 40°. This result is an evidence for expanding the standard of inclination angle 30° suggested in the 'Guidelines for Installation and Management of Ecological Pathways' to a maximum of 40°. However, further research is required in that the escape ramp targets not only Korean frogs but also various small wild animals. However, considering that various wild animals are affected by artificial canals, additional studies using various target wild animals are needed.

  • Constructing a long, linear structure such as a high-way may cause the break-up of the natural ecology by cutting off the trails of animals. We could observe 12 kinds of mammals, 49 kinds of birds and 10 kinds of amphibia and reptilia at the research area. With this research, we were so sure of the necessity of building ecological corridors to prevent the ecological break-up of wild animals that we studied the building and maintaining of 3 types of ecological corridors; tunnel types, over-bridge type and line type.

  • This paper deals with the isolation of citrate-utilizing variants of Escherichia coli ($Cit^+$ E. coli) from the animals, their biochemical reactivity and antibiotic susceptibility, and whether the citrate utilizing ability is transmissible. One hundred arid twenty-three isolates of $Cit^+$ E. coli were obtained from cattle and pigs. but from other animals, no isolates were obtaied. Antibiotic susceptibility testing of $Cit^+$ E. coli was performed by the agar dilution method, using the following 9 antibiotics, chloramphenicol(CP), tetracycline(TC), streptomycine(SM), kanamycin(KM), colistin(CL), gentamicin(GM), cephaloridine(CR), aminobenzycillin and nalidixic acid(NA). All the variants tested were susceptible to KM, CL, GM, CR and NA. Of all the variants, 80(65%) were resistant to the drugs tested and resistance to TC and SM was most frequent. The transmission of the ability to utilize citrate on Simmons citrate agar at $37^{\circ}C$ was demonstrated in 78(67.8%) out of the 115 $Cit^+$ E. coli. There were no significant difference in the transfer rates of citrate utilizing ability between resistant and susceptible variants to above 9 drugs. Of 123 isolates, 8 were lost their citrate utilizing ability, spontaneously.

  • Asia hosts more than half of the world's 1 billion goats and is also where domestication of wild goats began. Goats, including dairy goats, are adapted to a wide variety of harsh environments and thus play key roles as providers of nutrition, food security and socio-economic status to their human owners in many low-income Asian countries. In many countries in Southeast and East Asia, medium and large scale commercial dairy goat farming can be profitable enterprises because of the high price of goat milk, and good demand due to its health and medicinal properties. In some Asian countries, dairy goats play important roles in non-commercial activities, including use as educational animals in elementary schools in Japan and show animals in Indonesia. Dairy goat farmers in Asia are faced with numerous challenges, such as a shortage of high producing animals adapted to the local environment, lack of quality feeds during a prolonged dry season, many diseases and difficulty getting their product to market, however, the increasing demand for goat milk in the newly developed and developed economies in Asia provides an optimistic future for dairy goat production in this region.

  • Salmonella I 4,[5],12:i:- was a monophasic variant of Salmonella (S.) Typhimurium and notorious for re-emerging candidate which would replace S. Typhimurium DT104 for antibiotic resistance. Recently, isolation rate was increased on human and industrial animals but there was no case in domestic animals but human in Korea. This was first isolation case from domestic animals in Korea. The five isolates from feces of duck (n = 3), chicken (n = 1), and wild bird (n = 1) showed antibiotic resistance against cephems and aminoglycosides. These means that the spread of emerging bacterial pathogens to domestic animals and the need of systemic management for Salmonella I 4,[5],12:i:-.

  • Animals, as a part of nature, have much influence on children's emotional development and are one of children's favorite subjects of design. This study analyzes the differences in animal expression methods and types of animals, in relation to gender and item based on a collection of children's clothing and accessories that use animal as their theme. The collection consists of 148 clothing and 75 accessories (total of 223 items), which were collected from on-line shopping sites for children's clothes. Analysis results showed the following observations. Animal expression was categorized into four methods: emblem, illustration, character, and pattern.(The most common method was character, followed by pattern, illustration, and emblem. In relation to gender and clothing item, animal expression methods varied widely:(character was the most popular for) boys' t-shirts and accessories, while girls' bottoms and dresses. As for (animal) types, Mammalia was the most common, followed by birds and insects. Dogs and puppies were popular both genders.(However, differences in preferences existed as) boys liked big and wild animals such as bears, tigers, and foxes, while girls liked small and cute animals such as rabbits, cats, owls, and butterflies. Based on these results, six types of animals (rabbits, elephants, large-beaked bird Toco Toucans, fish, penguins, and bees) were selected as themes for kids' vest designs and, among them, three designs were made.

Food Culture of Korean Peninsula in the Neolithic Period Described in Daegok-ri Petroglyph (대곡리 암각화(大谷里 岩刻畵)에 나타난 신석기시대 한우도(新石器時代 韓牛島)의 식생활문화(食生活文化))

  • The present study examined the characteristic of regional food culture observed in prehistoric Daegok-ri petroglyph based on the history of art, archeological materials and existing whale eating customs. Daegok-가 petroglyph expressed animals in the sky, on the land and in the sea. According to the relic, the most preferred land and marin animals were deer and whale, respectively. In terms of petroglyphic techniques. earlier patch engraving was used mainly to express marin animal whale, and later line engraving to express land animal deer. This implies the possibility that as whale hunting declined due to regional environmental change the source of protein was switched to land animals. Among relics found in Dongsam-dong shell mound, which is a remain from the Neolithic Period, whale bones appear only in shell mounds of the Neolithic Period in coastal areas, and shell mounds until the Ironze Age, which were the agricultural Age, were found the bones of land animals such as deer and wild boar. This shows that in the petroglyph thematic land animals expressed in line engraving, which is a technique later than patch engraving, were major food resources for the supply of protein. Moreover, in terms of art, Daegok-ri petroglyph describes 'advanced hunters', suggesting that it was the Neolithic Period and showing 문 aspect of regional food culture based on hunting and fishing. The credibility, which prehistoric men expressed in Daegok-ri petroglyph before the invention of letters, was also proved by archeological articles.
