PET allows non-invasive, quantitative and repetitive imaging of biological function in living animals. Small animal PET imaging with $[^{18}F]$FDG has been successfully applied to investigation of metabolism, receptor-ligand interactions, gene expression, adoptive cell therapy and somatic gene therapy. Experimental condition of animal handling impacts on the biodistribution of $[^{18}F]$FDG in small animal study. The small animal PET and CT images were registered using the hardware fiducial markers and small animal contour point. Tumor imaging in small animal with small animal $[^{18}F]$FDG PET should be considered fasting, warming, and isoflurane anesthesia level. Registered imaging with small animal PET and CT image could be useful for the detection of tumor. Small animal experimental condition of animal handling and registration method will be of most importance for small lesion detection of metastases tumor model.

Even though the number of pet animal and breeder are increasing, there is little study related to the funeral of pet animal in Korea. In this paper, the factors affecting pet animal's funeral is conducted based on the survey. The study proves that the awareness of the pet animal funeral is positive but underprepared for pet animal's funeral. Therefore, pet animal funeral businesses operated on the permit system and the current law should be legalized while clarifying the difference between wild animal and pet animal. Also the professionals related to animal funeral should be trained.

Many types of small animal imaging modalities, like micro-CT, micro-PET, and micro-SPECT, have been recently developed worldwide. Small animal imaging systems are now recognized as indispensable tools to validate efficacy and safety of new drugs or new therapeutic methods using the animal disease models. With increasing demands for small animal imaging in biomedical research, multimodal small animal imaging systems, like micro-PET/CT or micro PET/MRI, are now also being developed. Small animal imaging with spatial resolution and sensitivity comparable to human imaging is quite challenging since laboratory small animals are much smaller than human beings. Research activities in Korea on small animal imaging systems are reviewed in this paper. In the field of micro-CT and micro-PET, many world-class technologies have been developed successfully in Korea. It is expected that the developed animal imaging system technologies can be used in the development of clinical imaging systems in Korea in the near future.

Although recent studies have shown the usibility of [F-18]FDG small animal Positron Emission Tommography (PET) as a functional neuroimaging technique in behavioural small animal study, researches showing the detection power of functional changes in the brain are still limited. Thus, in the study, we performed [F-18]FDG small animal PET neuroimaging in the well-established fear behavioural experiment. Twelve rats were exposed on cat for 30 minutes after the [F-18]FDG injection. As a result, the brain activity in bilateral amygdala areas significantly increased in the fear condition. In addition, the fear condition evoked the functional activities of hypothalamus, which seemed to be related to the response to stress. These clear localization of fear related brain regions may reflect that a functional neuroimaging technique using [F-18]FDG small animal PET has functional detectibility enough to be applied in small animal behavioral research.

This paper introduces a customized pet care and training system based on information technology. A specific animal is recognized by nose-print recognition. Pet robot induces the animal to move to trainer device. Trainer device trains the animal by snack, play, and clicker, and it can be easily extended for specific training using add-on devices. Pet band performs vital sign monitoring, prevention of home escape, and measurement of exercise amount. By changing configuration, this system can perform various training programs such as mitigation of separation anxiety, induction to defecation place, and prohibition of tresspassing specific place. It also provides customized training by analyzing individual behavior of animal. It can exercise and play the animal when owner is out, and it can immediately notice to the owner when the animal has health trouble.

The aim of this study was to propose a fusion and registration method with heterogeneous small animal acquisition system in small animal in-vivo study. After an intravenous injection of $^{18}F$-FDG through tail vain and 60 min delay for uptake, mouse was placed on an acryl plate with fiducial markers that were made for fusion between small animal PET (microPET R4, Concorde Microsystems, Knoxville TN) and Discovery LS CT images. The acquired emission list-mode data was sorted to temporally framed sinograms and reconstructed using FORE rebining and 2D-OSEM algorithms without correction of attenuation and scatter. After PET imaging, CT images were acquired by mean of a clinical PET/CT with high-resolution mode. The microPET and CT images were fusion and co-registered using the fiducial markers and segmented lung region in both data sets to perform a point-based rigid co-registration. This method improves the quantitative accuracy and interpretation of the tracer.

Cryptosporidium is the most common protozoan that can infect a wide range of animals, including mammals and birds. Avian Cryptosporidium spp. can cause enteric and respiratory diseases which can be fatal in birds and some species are zoonotic. Companion birds have the potential as reservoir due to their close contact with humans. Pet shops are the major source of companion birds. However, few reports are available regarding Cryptosporidium spp. infection among companion birds kept in pet shops. The present study reports the prevalence and molecular characteristics of Cryptosporidium spp. among companion birds kept in pet shops in Japan. A total of 265 fresh fecal samples were obtained from birds kept in 4 pet shops; these birds belonged to 41 species in 3 bird orders. A nested polymerase chain reaction (PCR) assay targeting the small subunit rRNA gene was employed for the detection of Cryptosporidium spp. A total of 24 samples (9.1%) were positive, and Cryptosporidium spp. were detected from all pet shops. The prevalence of Cryptosporidium spp. in each of the bird orders was 6.5% (10/153) in Psittaciformes, 14.4% (13/90) in Passeriformes, and 4.5% (1/22) in Galliformes. Based on sequence analysis, 13 (54.2%) isolates were classified to C. galli, 8 (33.3%) were avian genotype III, and the remaining 3 (12.5%) were C. baileyi. No infection with zoonotic C. meleagridis and no coinfection with multiple Cryptosporidium spp. and/or genotypes were observed. The zoonotic potential of Cryptosporidium spp. infecting companion birds kept in pet shops in Japan is likely to be low.

In the era of Corona, companion animals provide a lot of comfort to people, and the Pet Pam group, who thinks of companion animals as family members, has appeared. There is also the Pet Pour phenomenon, in which young consumers spend less on their pets and spend on their companion animals. Despite these changes in the times, pet products, including pet food, are still highly dependent on imports. In addition, since domestic standards for cosmetics and supplies for companion animals have not been established, they rely only on cosmetic safety standards and regulations. In addition, the terminology for domestic pet cosmetics has not been established yet. Currently, only the Animal Protection Act related to companion animals has been amended in the domestic law, but in the case of Japan, the Companion Animal Feed Safety Act came into effect in June 2009. In the United States, the federal Food, Drug, and Cosmetic Control Act covers pet cosmetics and supplies. Germany, which has strong animal protection laws, has various national regulations on food and feed, and detailed national regulations are also provided on the website of the Food Safety Administration. National policies and environments should be established to manage and develop the companion animal industry in Korea as in such a country, and it is considered essential for the development of companion animal cosmetics and various companion animal industries.

As the number of companion animals reaches 15 million in 2022, the pet wear market is expected to grow at an average annual rate of about 14.5% from KRW 1.5684 trillion in 2014 to a market size of over KRW 6 trillion in 2027. However, most of the pet clothing and various supplies currently in circulation are either cheap, low-quality products imported from China or other countries, or expensive products released by overseas luxury brands. Therefore, it is urgent to develop a brand that can compete with luxury products coming from overseas by developing premium pet fashion products using high-end functional fabrics produced domestically. This study seeks to propose ways to revitalize the domestic pet fashion market by examining the current status of global pet fashion, the domestic textile industry, and the current status of the pet fashion market. The suggestions and expected effects are as follows. First, active support is needed for the development of products using domestically produced fabrics, such as raising awareness through various subsidy projects and contests. Second, it is expected that small and medium-sized businesses will be revitalized through the production of pet fashion products using high-quality functional knit fabrics produced in northern Gyeonggi Province. Third, it is necessary to produce high-quality premium products through continuous and intensive support from the government and collaboration between large corporations and small and medium-sized enterprises. Fourth, there is an urgent need to provide opportunities to train experts for the expected effects of starting businesses and creating new jobs.
