Dermatophytosis was found on the right front leg of a 4-month-old female African lion cub (Panthera leo) kept at a zoo with locally marginal alopecia. For diagnosis, culturing on sabouraud dextrose agar was performed and skin scrapings from the lesion were analyzed. The ones from the culture and skin scrapings were identified as Trichophyton mentagrophytes. A zookeeper that had been in contacted with the lion for artificial rearing developed skin lesions with well-defined erythematous plaques on the right arm about 1 month after the lesion in the lion was observed. The ringworm was probably transmitted from the lion through continuous contact.

It is important to identify the bacteria in snakes because they can cause disease; importantly, bacteria such as Stenotrophomonas maltophilia, Escherichia coli, Proteus vulgaris etc. could be pathogens especially in hospitalized, debilitated hosts, and immunocompromised patients. To analyze the distribution of snakes' bacteria in petting zoo, samples from 20 snakes were collected from 2002 to 2008. Nine bacteria species were isolated from both oral and cloaca while four and six species were identified only from oral and cloaca, respectively. Except for Actinobacter sp., all of the identified strains are opportunistic pathogens, and most of them can cause nosocomial infections in humans. Present results indicate that prevalence of various zoonotic bacterial strains in snakes could be involved in potential transfer of these bacteria into caretakers and other animals. Therefore, it needs to examine the antibiotic resistance of these pathogens to prevent outbreaks.

A one-year-old female sika deer died suddenly with no preliminary signs during exhibition at a zoo. At necropsy, the carcass was emaciated and had dried fur. Examination of the thoracic cavity revealed a diaphragmatic rupture measuring 2 cm in diameter and a fracture in the middle of the right eighth rib. The liver and lungs had irregular circular discolorations caused by diaphragmatic rupture and subsequent herniation. Dark-brown-colored ascitic fluid, hydrothorax, and yellowish hydropericardium were also observed. The cause of death was determined to be diaphragmatic rupture caused by a rib fracture, which led to respiratory imbalance and circulatory disorders.

Jejunal volvulus was diagnosed in a captive 12-year-old male striped hyena at necropsy. The animal was presented with decreased appetite, dullness, vomiting, and mild abdominal distention intermittently for about two months. Then, the animal was found anorexia, lethargy, depression, red brown colored vomiting materials, and decreased defecation from 10 days before death. At necropsy, jejunal volvulus was found about 1 m in length, and coalescence was observed at the inner membranes of jejunum. The parenchyma of the kidney was congested, and the bladder was filled with hematuria. These conditions might cause shock by renal failure that led to death. To prevent volvulus in a captive striped hyena, it is needed to improve zoo environment and early diagnosis using ultrasonography and X-ray.

An aged (14 years old) female snow leopard exhibited renal calculi and pyelonephritis at necropsy. The animal experienced appetite loss, mild diarrhea, polydipsia, and difficulty breathing, and was curled up and staggering on its hind legs 2 days before death. Large calculi were found obstructing both sides of the renal pelvis. The left-side calculus was larger than that of the right side. These calculi had rough surfaces and were $15{\times}21mm$ and $9{\times}14mm$, respectively. The bladder was filled with dark, cloudy urine. Multiple ulcerous lesions were found in the inner layer of the bladder. Enterococcus faecalis and Proteus mirabili were identified via microbiological examination of the urine. Under microscopic examination, urine struvites were observed in the pyuria sediment in the bladder. To our knowledge, this is the first documented case of nephrolithiasis in a captive snow leopard.

2단계 잠금 규약은 데이터베이스에서 트랜잭션의 직렬성을 보장하는 방법이다. 분산 클라우드 시스템에는 분산된 노드들에 의한 합의 문제가 필연적으로 존재하여, 이는 분산 시스템에서 2단계 잠금을 비롯한 데이터베이스 이론의 적용을 어렵게 한다. 본 논문에서는 ZooKeeper를 이용하여 분산 클라우드 시스템에서 활용 가능한 2단계 잠금의 구현을 보이고, 이것이 트랜잭션의 직렬성을 보장함을 확인한다. 또한 분산시스템의 잠금 과정에서 발생할 수 있는 교착 상태 해결의 구현을 보인다.

A yellow-billed spoonbill kept at the zoo was found dead. As a result of the necropsy, the stomach (gizzard and proventriculus) and duodenum were full of undigested fish bones, and the undigested sharp fish bones were lodged in the gastric mucosa and clumped together, blocking the lumen. Thereafter, the intestinal wall was perforated and peritonitis occurred causing death. The cause of the fish spines becoming lodged in the gastrointestinal tract is unknown. It can only be assumed that there was a lack of a mechanism for the yellow-billed spoonbill in a zoo to go around and pick up grit or small stones and assist in mechanical crushing in the gizzard.

Maras (Dolichotis patagonum) are monogamous and mate for life. A pregnant mara, 6.15 kg, died after forelimb amputation surgery at Seoul Zoo on February 28, 2009. In the bicornial uteri, two fetuses were found in each uterine horn. The placenta was chorioallantoic, hemochorial, discoidal and labyrinthic. The entrance of cervix had a deep fornix and no cervical folds were observed in the cervix. This report is the first about Patagonian mara and helpful for clinicians who deal currently or in the future with exotic pet animals.

Subject headings support the effective access of children's picture books. However, it is difficult to select subject terms from titles or table of contents in children's picture books because of their relatively little textual information. Therefore, it is necessary to assign subject terms to each picture book. However, it is not adequate to use general subject headings because the types and levels of general subject headings are different from special subject headings for the children's materials. For this reason, this study aims to develop subject headings for children's picture books. The subject terms in A to Zoo were selected, and the selected terms were translated into Korean and modified for the Korean culture and language. Other reference books, such as Elementary Korean Dictionary, were also used to determine adequate terms for children. The resulting subject headings were assigned to the recommended picture books for children and used to search by subject, browse, and recommend books.
