To restore the Gold-spotted pond frog (Pelophylax chosenicus), a Korean endangered frog, 600 captive-reared individuals were reintroduced between August and September 2019 into an aquatic garden in the National Institute of Ecology where P. chosenicus had previously inhabited. After reintroduction, six post-release monitoring sessions were conducted from August 2019 to May 2020. Monitoring was performed using three methods (counting calls, observation, and capture) from sunset to midnight near release sites, eliminating potential threat factors. Snout-vent lengths and body weights of recaptured individuals were measured before they were released immediately. We noted that both snout-vent lengths and body weights of recaptured individuals were slightly higher than those before. The average recapture rate was 4.66%. Reintroduced frogs were recaptured at the last monitoring session conducted in May 2020, indicating that these reintroduced frogs hibernated during the winter successfully. We found that these reintroduced frogs successfully settled after release. This result will be useful for establishing management strategies for endangered frogs in Korea. Particularly, post-release monitoring could be an essential approach in the restoration program of a target species.

Korean fir(Abies koreana E.H.Wilson 1920), endemic tree species of Korean peninsula, is considered as vulnerable and endangered species to recent rapid environmental changes such as land use and climate change. There are limited activities and efforts to find natural habitats of Korean fir for conservation of the species and habitats. In this study, by applying SDMs (Species Distribution Models) based on climate and topographic factors of Korean fir, we developed Korean fir's predicted distribution model and explored novel natural habitats. In Mt. Shinbulsan, Youngnam region and Mt. Songnisan, we could find korean fir's two novel habitat and the former was the warmest($13^{\circ}C$ in annual mean temperature), the driest(1,200mm~1,600mm in annual rainfall) and relatively low altitude environment among Korean fir's habitats in Korea. The result of SDMs did not include mountain areas of Gangwon-do as habitats of A. nephrolepis, because there were different contributions of key habitat environment factors, summer rainfall, winter mean temperature and winter rainfall, between A. koreana and A. nephrolepis. Our results raise modification of other distribution models on Korean fir. Novel habitat of Korean fir in Mt. Shinbulsan revealed similar habitat affinity of the species, ridgy and rocky site, with other habitats in Korea. Our results also suggest potential areas for creation of Korea fir's alternative habitats through species reintroduction in landscape and ecosystem level.

The purpose of this paper is to examine willingness to pay (WTP) for endangered species, the Korean goral, of Woraksan National Park in South Korea. The median of the WTP is adopted to estimate the value because it will not be affected by the extreme values. The estimated household median WTP using a logit model for Korean goral conservation in Woraksan National Park was 15,221 won. The estimated value of the WTP in relation to the Korean goral has some policy implications. especially in terms of implementing policy to protect the Korean goral. The result shows that the public conservation program does have a positive WTP for the conservation of the Korean goral. This implies that the Korean goral is an important species that needs to be maintained, the government has been expended a large sum of money in an attempt to protect it.

Drug-induced autoimmune hepatitis (DIAIH) is an increasingly recognized form of drug-induced liver injury that leads to a condition similar to idiopathic autoimmune hepatitis. A number of drugs have been associated with DIAIH, minocycline is one of the most well characterized. Minocycline is a semisynthetic tetracycline antibiotic used in the treatment of acne vulgaris. Minocycline-induced autoimmune hepatitis presents with serologic and histologic features similar to idiopathic autoimmune hepatitis. However, the natural history and outcomes of these two conditions differ significantly. The majority of patients with minocycline-induced autoimmune hepatitis experience complete resolution of symptoms after withdrawal of the medication. Some patients may require a short course of steroids and rarely use of an immunomodulator to achieve resolution of disease. Recurrence of symptoms is rare and typically only occurs with reintroduction of minocycline. It is important for primary care providers to consider minocycline-induced autoimmune hepatitis when liver injury develops during minocycline therapy.

The mainstay in the management of mild to moderately dehydrated children is fast rehydration by using hypotonic ORS (oral rehydration solution) and complete resumption of normal diet, including lactose-containing formula after 4 hours rehydration. Since the majority of young children with uncomplicated acute diarrhea will tolerate large amounts of undiluted non-human milk, withholding food and milk from children during diarrhea is not recommended anymore, regarding time to resolution and diarrhea control. In addition, routine dilution of milk and routine use of lactose-free formula are not necessary after fast ORS therapy. Breastfed infants and children fed with solid foods may safely continue receiving their usual diets during diarrhea instead of gradual reintroduction of feeding. However, young infants or children with severe diarrhea or malnutrition should be carefully treated under supervision if fed with lactose containing, non-human milk exclusively.

Nationalism can solidify national unity and ideology but sometimes causes conflicts in human societies. Interestingly, it affects tiger conservation as well. Collaborative efforts are imperative for tiger conservation due to their vast home ranges which cross political boundaries and the limited financial resources. However, tiger states have not shown substantial commitment to collaboration. The nationalism that is entrenched in tiger conservation provides a credible explanation for this passive collaboration among nations. One type of nationalism occurs within a country by favoring one particular subspecies over another. The other type of nationalism occurs when former range countries want tigers. Instead of contributing to saving tigers in current habitats, they are eager to bring tigers back to their political boundaries regardless of the tremendous financial resources required and the lower chance of success. Considering nationalism in tiger conservation, tigers, just like humans, may need a passport for a better chance to survive.

Clozapine is the first and most effective atypical antipsychotic drug for treatment-resistant schizophrenia (TRS). After withdrawal of clozapine due to concerns of agranulocytosis, clozapine was reintroduced with a comprehensive safety monitoring system, the clozapine patient monitoring system (CPMS). The reintroduction was a response to the pressure from psychiatrists and patients with TRS and their families. Clozapine is still the best single agent for the treatment of TRS. However, approximately 30% of patients with TRS still show psychotic symptoms. In patients with clozapine-resistant schizophrenia (CRS), augmentation of other antipsychotic agents could be considered after a thorough evaluation of proper clozapine treatment. In this review, the status of clozapine in patients with TRS and CRS will be discussed.

Cancer vaccine is an active immunotherapy to stimulate the immune system to mount a response against the tumor specific antigen. Working as a stimulant to the body's own immune system, cancer vaccines help the body recognize and destroy targeted cancers and may help to shrink advanced tumors. Research is currently underway to develop therapeutic cancer vaccines. It is also possible to develop prophylactic vaccines in the future. The whole cell approach to eradicate cancer has used whole cancer cells to make vaccine. In an early stage of this approach, whole cell lysate or a mixture of immunoadjuvant and inactivated cancer cells has been used. Improved vaccines are being developed that utilize cytokines or costimulatory molecules to mount an attack against cancer cells. In case of melanoma, these vaccines are expected to have a therapeutic effect of vaccine. Furthermore, it is attempting to treat stomach cancer, colorectal cancer, pancreatic cancer, and prostate cancer. Other vaccines are being developing that are peptide vaccine, recombinant vaccine and dendritic cell vaccine. Out of them, reintroduction of antigen-specific dendritic cells into patient and DNA vaccine are mostly being conducted. Currently, research and development efforts are underway to develop therapeutic cancer vaccine such as DNA vaccine for the treatment of multiple forms of cancers.
