In order to investigate the contents of total mercury in zoo animal located near in Seoul, we measured the contents of total mercury in fur and feather collected in zoo animal by the Mercury Analyzer. The contents of total mercury in mammals was $61.56\pm 20.32 \mu g/kg$, but in birds $659.49\pm 162.73 \mu g/kg$. Compared with feeding pattern, the contents of total mercury of omniverous and carniverous were detected higher than those of herbiverous in mammals, and also same as in birds. The contents of total mercury of Cuculidae and Ciconidae were detected highestly among classification of family in zoo animal, but those of Camelidae and Cervidae were detected lowestly. Of carniverous, 30.5% was higher than $1000 \mu g/kg$, but the ratio of omniverous detected less than $100 \mu g/kg$ was 45.5%, and in herbiverous 95.4%.

In order to elucidate the human impact on the distribution of cellular slime molds, samples were collected from 3 types of forest ; natural forests(Mt. Deogyu and Mt. Tsukuba), semi-natural forests(Seoul Great Zoo and Tama Zoo), artificial forests(Seoul National University and Tokyo Gakugei University) .The distribution of cellular slime molds in mountains was different from that of zoo and universities. In mountains, endemic species was occurred and species diversity was higher than in zoo and universities. In zoo and universities disturbed by human, Dictyostelium sphaerocephalum was occurred with higher importance value than in mountains. 6 species were selected to investigate the effect of temperature on froctification; Polysphondylium canlidum, D. delicatum. D. firmibasis, D. sphaerocephalum P. violaceum, D. purpureum. P. violaceum and D. purpureum had an optimum temperature for fructification around 25~3O˚C but the others around 22~23˚C. The degree of sensitivity to temperature was as follows; P. candidum >D. lelicatum > D. firmibasis > D. sphaerocephalum > P. violaceum > D. purpureum. Key words: Human impact, Cellular slime molds, Occurrence and distribution, fructification, Dictylostelium delicatum. Dictyostelium sphaerocephalum.

Hepatitis E virus (HEV) can infect not only human but also several animals. This study has been conducted to evaluate the comprehensive anti-HEV seroprevalence in zoo animals in Korea. Anti-HEV antibodies were identified in 14 of 64 zoo animal species. HEV antibodies were detected for the first time in Eurasian Lynx, Setland Pony, Fallow Deer, Ezo Sika, Formosa Deer, East Wapitis, Barasingha, Corriedale, American Bison, Guanacos, Reticulated Giraffe, and Saanen. These results indicate that the several zoo animal species were exposed to HEV.

The purpose of this study was to examine antibody titers to structural protein (SP) of the foot-and-mouth disease (FMD) virus after vaccination in animals of the Seoul zoo. After the initial inoculation of FMD vaccine to the susceptible animals of the zoo, a total of 235 blood samples were collected from 42 species of zoo animals during treatment or necropsy. All samples were tested by using enzyme-linked immunosorbent assay (ELISA). The overall positive rate of SP antibodies against FMD virus was 94.0% (221/235). However, the positive rates varied according to animal species. The results of positive rates in 30 species were 100% but in 12 species were 50-94.7%. We showed that most animals that have received FMD vaccine in Seoul zoo have been reached to the level of herd immunity against FMD virus after the vaccination. To the best of our knowledge, this study would be the first report for monitoring the vaccine-induced SP antibody titers against FMD virus after vaccination in various zoo animal species in Korea.

This study aims to analyze the change process in order to set the improvement strategies for the zoo in the Seoul Children's Grand Park. The zoo can be reviewed through three significant time periods with noticeable changes. As a framework to analyze the major changes that happened in the zoo, this study looks at the changes in terms of the planning aspect as well as the animal welfare and program operation aspect. The findings are as follows: first, the era of general theme park turned out to have focused on exhibiting animals to meet visitor demands by expanding the zoo area of the zoo without enlarging stockyards for the animals. Second, the environmental park era created a zoo having entertaining and educational functions by arranging animal houses with the concept of zoological taxonomy and introducing animal behavioral enrichment, animal welfare programs and visitor participatory programs. The era of the zoo as an Urban Cultural Park improved old animal houses and facilities for the welfare of the animals and increased educational programs to preserve species and provide environmental education. The current status of the zoo turns out not to meet the conditions for creating an ecological zoo, which is the overall goal for contemporary zoos. The improvement strategies based on the analysis through three different eras are three-fold. First, the zoo needs to improve the boundary conditions of the animals to showcase animal wildness through landscape immersion. Second, the zoo should provide a shared environment for animals from the same habitats by changing the classification methods from the existing polyphyletic taxon to a classification that considers ecological habitat. Third, the zoo needs to develop various ecological education programs by supplementing specialists in professional education.

Well designed idealistic zoo requires basically a condition that the zoo is much ecologically considered for the exhibited animals, and secondly where they offer leisure for the visitors' convenience and pleasure. But it is not easy to find a zoo where they have actualized these both-sided purposes. We cannot but discuss the problem of design caused by a lack of plan-ability that is necessary when the zoo is designed. It is because every elements are not wholly unified and those diversified contents aren't mutually harmonized. Therefore, a zoo has to meet the requirement of the pleasure, study, inspection and leisure deserves a special emphasis. The zoo requires a synthesized speculation of design which the elements-Identity Program, Furniture System, animal's ecological environment, animal's showroom, cage and facilities etc., - are mutually harmonized. This study is a combined-design research on the Daegu Dal-sung Park in this concept. 1 have newly analyzed the Dal-sung Park's utilizing form in order to harmonize both visual and ecological environments.

The Formosan sika deer (Cervus nippon taiouanus) is an endemic subspecies in Taiwan. The original wild deer has been extinct since the late 1960s. The largest captive population is located at the Taipei Zoo. Except for infectious disease outbreaks, no systemic medical research has been reported for this subspecies. This study was conducted to analyze the medical status of the captive Formosan sika deer population, including the hematological and serum chemistry characteristics. To accomplish this, medical records for 34 Formosan sika deer from January 2003 to January 2014 were acquired and analyzed. The most common illness and cause of death was trauma, followed by gastrointestinal and respiratory disease, respectively. The hematologic and serum chemical values of healthy adults were quite different from those of sika deer (Cervus nippon yesoensis). This study provides a closer medical understanding of this subspecies and the results will facilitate its management.

A three-month-old female African buffalo born at Seoul Zoo showed signs of abdominal distension, bulging of the perineal skin, and small stool volume compared to feed intake. Upon physical examination, atresia ani with rectovaginal fistula was diagnosed. This case was subjected to surgery under inhalation anesthesia after injecting a sedative. Surgery was performed in two steps: anal reconstruction and closing the rectovaginal fistula. First, a circular skin incision was made at the end of the rectal pouch to create an anus, and then the skin of the anus and the mucous membrane of the rectum were brought into apposition by simple interrupted sutures. Second, the rectovaginal fistula was ligated on both vulval and anal side. Antibiotics were administered on every alternate day and the sutures were removed at ten days surgery under sedation. The rectovaginal communication was closed and the calf was able to urinate and defecate normally. The animal grew to become a normal adult without any complications. This is the first case report of atresia ani with rectovaginal fistula in an African buffalo, that was successfully treated by surgical intervention.

Most captive canids and felids at Zoos in advanced countries have been examined enough to apply artificial reproductive techniques to them. We investigated reproductive hormones and vaginal epithelial cells of a 6-year-old, female coyote, hoping these data could eventually be extended to artificial insemination with frozen-thawed conspecific semen at Seoul Zoo. As a relative of pet dogs, coyote exhibited a similar appearance with only minor differences. In vaginal smear, an increase in the number of superficial cells suggests that the bitch has reached a state close to estrus. A sudden decrease of estradiol and increase of progesterone is considered as a preovulatory event. Vaginal epithelial cells and hormones might be useful for determining the optimal time of artificial insemination in coyotes' breeding.
