Responsible environmental behavior of Youths who will live in the 21C needs the ‘Personalization of Environment’, which means the process or the result of awareness to the non-personal environment as the personal environment to show the responsible environmental behaviors through the intended physical and psychological contacts to environment. This study intended to analyze various programs of national parks, zoo, children's garden and Project Learning Tree in the United States and to discuss the possibility of ‘personalization of environment’ and implication for environmental education of Korea. Literature review, field trips, personal interviews and internet searches were used to collect information and data. Programs of North Cascade National Park, Mt. Rainier National Park and 4-H Children's Garden in Michigan State University showed the cases of direct personalization of environment focusing on the direct contact with nature. The programs of Binder Park Zoo in Battle Creek and Project Learning Tree showed the possibilities of indirect personalization of environment forming meaningful relationships with nature through various indirect activities. It is suggested that various natural education programs in Unites States make nature and places meaningful for the people and it needs to be applied for the environmental education programs in Korea.

The aim of this study was to diagnose the fertility of a female western lowland gorilla kept in Seoul Zoo, in accordance with age by analyzing the fecal sex hormone metabolites. The study was conducted in two period of times, when the animal was from 35 to 37 years old and when the animal was from 40 to 42 years old. Non-invasive method by using fecal samples was used for safe and efficient fertility diagnosis. We collected the feces from the enclosure at least three times a week. Then $17{\beta}$-estradiol and progesterone, which are fecal sex hormone metabolites, were measured by time-resolved fluoro-immunoassay to compare the menstruation cycle and the annual reproductive cycle. For the duration of the primary study (when the animal was 35~37 years old), irregular menstruation and high concentrations of estradiol and progesterone were observed. However, menstruation was hardly observed and the concentrations of both hormones were statistically very low in the period of secondary study (when the animal was 40~42 years old). This observed phenomenon in our study was very comparable to menopause in adult women; therefore, it was confirmed that our female gorilla has reached menopause because of the natural aging, as they become older.

Blastocystis sp. is a kind of protozoa living in the intestinal tract of human and animals, which will cause intestinal diseases such as diarrhea, abdominal distension and vomiting. This paper was aimed to understand the infection of Blastocystis sp. In golden monkeys and the transmission path in North China. Thirty-seven feces samples from golden monkeys and 116 cockroach samples from Shijiazhuang Zoo were collected from July to October 2019 for PCR analysis of Blastocystis sp. Genetic diversity analysis was further conducted on the samples with positive PCR results. The results showed that the infection rate was 48.7% (18/37) in golden monkeys and 82.8% (96/116) in cockroaches, respectively. The genetic evolution analysis based on small subunit ribosomal RNA demonstrated that three subtypes (ST) of Blastocystis sp. including ST1, ST2, and ST3 existed in the intestinal tract of golden monkeys, while only ST2 was detected in the intestinal tract of cockroaches. This paper may provide supports for the quarantine and control of Blastocystis sp. for the zoo in Northern China.

A 3-year-old male lion at Gwangju Uchi Zoo presented for acute onset of haemorrhagic diarrhea and died. The lion showed reddening of the anus as the cause of haemorrhagic enteritis. Necropsy revealed a severe haemorrhagic colitis. Grossly, lesions included icterus, excess pericardial fluid. dark kidneys, and an enlarged, friable liver. The intestines were flaccid, thin-walled, dilated, and 9as-filled. The spleen was enlarged and pulpy because of congestion. Most of organs were rapidly postmortem autolysis. Histopathologically, the intestines were edema and transient leukocyte infiltration of the lamina propria, followed by necrosis. Especially of the intestinal submucosa was edematous, haemorrhagic, or filled with leukocytes. The crypts remained intact or dilated. C perfringens was isolated from a lion at bloody feces, and identified C perfringens type A, confirming the presence of C perfringens $\alpha-toxin$ by PCR. These results were suggested that the case were diagnosed as enterotoxicosis in the lion. More studies are needed on lion enterotoxemia. especially of its etiopathogenesis, in order to develop more efficient prevention for this disease.

The concept about zoo is changing from the animal exhibition which simply contained the animals to the ecological zoo which has the function of preserving the animal species. At the central point of maintaining such role, the basic principle called the animal welfare lies obviously. Korea has applied the animal welfare principles such as carrying out the enrichment in the zoos since 2003, but there has not been any institutional device to evaluate and examine the application of the animal welfare so far. This study aims to confirm the level of animal welfare in Korea and suggest a developmental direction. For the purpose of the study, 12 zoos in Korea were evaluated according to 68 evaluating categories. 'Five Principles of Animal Welfare' in the Secretary of State's Standards of Modern Zoo Practice were selected and carried out as the evaluation categories, and the result, from the highest to lowest score given, was 'provision of food and water', 'provision of protection from fear and distress', 'provision of health care', 'provision of an opportunity to express most normal behaviours', and 'provision of a suitable enrichment' with the overall score of the entire Korean zoos being 2.86 (${\pm}$ 0.56). It was also confirmed that in order to improve the animal welfare of the Korean zoos, the animal management system must be standardized and organized. The evaluation and feedback, the active practice of animal welfare and its legislative support should be provided to establish an effective institutional device as well.

Nucleotide sequences of mitochondrial DNA (mtDNA) of 19 leopard cats (Prionailurus bangalensis euptilura) obtained from Seoul grand park zoo in South Korea were determined for analysing genetic diversity. In the leopard cats, 3 haplotypes of the partial cytochrome b sequences (603 base-pairs, bp) were identified. Haplotypes obtained from those genes showed existences of at least 3 maternal lineages of leopard cats in Korea. Tamura-Nei nucleotide distance among 3 haplotypes were 0.00. Molecular phylogenetic tree showed the similar clustering of haplotypes for genes. Meanwhile, no individual variations within the leopard cats in S. Korea. Genetic surveillance system of leopard cats in S. Korea is warranted for maintaining biological conservation.
