This study was attempted to analyze the current status of curriculums programs in the pet-related departments in the fifteen colleges in Korea which have operated the relevant courses of major practice since they were newly established in 2003 or later. Thus, this study aimed to suggest how to develop the curriculums for pet-related departments so that the study had the goal of creating the common gold standards between the Korean cultural industry of companion animal and the relevant curriculums. Based upon the results listed above, it is considered that pet-related curriculums should be developed and operated as follows: First, the curriculums preferred highly by both undergraduates and employees should be selected and operated. Second, liberal arts courses concerning companion animal culture required to cultivate cultural comprehension for basic abilities should be opened. Third, major courses concerning animal-assisted therapy (AAT) together with the existing major practice courses should be established so that undergraduates can grow into professionals. Fourth, to do so, appropriate machines and instruments for major practice laboratories should be introduced and maintained. fifth, some pet-related departments substituting major theory courses for major practice courses should improve their organizations. Sixth, standardized curriculums fur pet-related departments and an evaluating institute fur them should be arranged and founded. Finally, the college management should invest constantly in the suitable major practice laboratories and their facilities for companion animal industry as well as curriculum operations.

In South Korea, the number of households that rear companion animal has been gradually increasing. With the rise of household dogs, the frequency of humans that are being bitten by another's dog has also increased. This type of accident, which is known as a dog bite accident throughout the United States. It can cause significant physical and emotional damage to the victims and may result in grave injuries or death. Dog bite accidents are serious public health problems and can cause immeasurable hidden costs to the community. South Korea has enacted several laws to address dog bite accidents, which include the Animal Protection Act, the Civil Act, and the Criminal Act. On March 20, 2018, the Animal Protection Act was amended to reinforce the current legislation. These amendments addressed the duty of care owed by a companion dog owner to society members and the punishment that an owner of a fierce dog would face in the event of a dog bite accident. Conversely, several states in the United States have enacted a single law that regulates the details regarding dog bite accidents, such as the type of dog or animal, the type of damage, the scope of compensation for damages, and the scope of recognition of liabilities. This paper is intended to review the present situation of dog bite legislation in several states in the United States, which have a variety of laws that address dog bite accidents, and compare them with current South Korean dog bite legislation. Through this research, this paper will discuss what issues may exist in South Korean's current dog bite laws, analyze the responsibility of companion dog owners, and provide solutions to any issues that are discovered.

A rumen simulated continuous culture (RSCC) system was used to study the influence of supplementation of the three different types of protein sources such as urea, casein and soy protein on rumen microbial synthesis in terms of rumen microbial synchronization. The urea treatment showed the highest pH value. Ammonia nitrogen concentration was rapidly increased after feeding and not significantly different in the urea treatment (13.53 mg/100 ml). Protozoa numbers were not significantly different for soy protein and casein treatment compared to urea treatments during incubation. The average concentration of total VFA (mMol) was not detected with significant difference among treatments, but iso-butyrate production showed the highest for soy protein treatment among treatments (p<0.001). The lowest concentration in total iso-acids (iso-butyrate and iso-valerate) production was observed in urea treatment. The soy protein treatment showed no significantly change in acetate/propionate. The amounts of dry matter (DM) out flow showed no significant difference among treatments. Organic matter (OM) flow was the highest for urea treatments and the lowest for casein treatment (p<0.03). The nitrogen flow for casein treatment was not significantly different from other treatments. The efficiency of microbial protein synthesis in terms of microbial nitrogen (MN) synthesis (g MN/kg ADOM) digested in the rumen was highest for casein treatment (58.53 g MN/kg ADOM) compared to soy protein and urea (p<0.05). This result suggests that rumen ammonia releasing rate may influence on microbial protein synthesis in the rumen.

None of the numerous published canis idiogram and karyotypes has yet been generally accepted as a standard one because the dog has 76 acrocentric autosomes of similar size and shape. The karyotypes of DongGyeongi dog were analysed by conventional trypsin/Giemsa staining (GTG-banding techniques), and were compared with one another. There were no variations in karyotypes which were analysed by conventional GTG-banding techniques, but differences were observed in G-banding patterns with sapsaree (or canis familiaris strains). It is not clear that these disagreements in G-banding patterns between strains of dog were caused by chromosome polymorphism or a difference in interpretation.

The effect of insect feed powder on the growth performance and economic evaluation of ducks was investigated. One hundred and twenty-old Pekin ducks were randomly assigned to two dietary treatments (0% and 1% Hermetia illucens powder) with three replicates of 20 birds each for 14-42 d. No significant (p>0.05) difference in growth performance between the control and 1% H. illucens powder was observed, except the feed conversion ratio (p<0.05), for the experimental period. The treatments with 1% H. illucens powder improved the economic indicators in comparison with the controls. Therefore, a diet supplemented with 1% H. illucens powder could significantly improve the feed conversion ratios and increase the economic indicators.

The history of animals raised by humans began in prehistoric times, and in modern times they were classified as livestock and pets. As social awareness changes, the term 'companion animal' is used instead of 'pet', and related content has also become more diverse. Recently, digital contents such as virtual pet training, memorial space, and AI health diagnosis using metaverse and AI technology are developing. Developed digital content makes pet care convenient and provide emotional support and economic benefits to users. As technology develops and content becomes more diverse, the relationship between pets and humans will become closer in the future, and related laws and ethical guidelines will need to be established.

The purpose of this study was to investigate the effect of breeding experiences of companion animals on elementary school students' interest in science, science curiosity, and science self-concept in relation to companion animals that are rapidly increasing in modern society. To achieve the purpose of this study, level of four hundred and seventy-four 6th grade at elementary school students' interest in science, science curiosity, and science self-concept according to breeding experiences of companion animals were compared and analyzed through ANOVA and independent sample t-test. As a result of the analysis, students who have experience in raising companion animals have higher interest in science, science curiosity, and science self-concept than students who have no experience in raising companion animals. It is believed that students participate in breeding activities of companion animals with interest and curiosity, and that self-concept has increased due to the process of acquiring knowledge necessary to raise companion animals and successful breeding experiences. The results of this study are meaningful in that they discussed the implications of breeding experiences of companion animals for science education, using companion animals that have not been studied much in the field of science education so far.

Red ginseng marc is a by-product of Korean red ginseng (panax ginseng CA Meyer) and contains ginsenoside which has pharmacological effects. The Korean red ginseng marc was fermented with Bacillus subtilis (RGMB). This study was carried out to investigate the RGMB effect on swine immunity. The variation of ginsenoside depending on the RGMB fermentation time was analyzed. Swine (Landrace${\times}$Yorkshire) were divided into control group (basic diet) and RGMB group (RGMB 1% diet). One percent RGMB was fed to the RGMB group for 28 days. The biochemical parameters, cytokine and immunoglobulin were analyzed. For 48 hours of fermentation on RGMB, ginsenoside Rb1 had increased 180.94%, Rg3 235.85%. Rg1 wasn't detected before fermentation, but was detected after 48 hours of fermentation. The RGMB had effect of deceasing initial AST concentration $79.33{\pm}12.85U/L$ to $54.00{\pm}14.46U/L$ in final and was significantly lower (P<0.05) than control in final. In final RGMB had significantly lower (P<0.05) ALT concentration of $48.57{\pm}8.26U/L$ comparing with control group of $65.43{\pm}10.31U/L$. RGMB had the effect of significantly decreasing (P<0.05) $IL-1{\beta}$, IL-6 and $TNF-{\alpha}$ concentration of $2.44{\pm}1.31ng/mL$, $0.71{\pm}0.36ng/mL$ and $0.51{\pm}0.21ng/mL$. The IgA concentration had significantly increased (P<0.05) in RGMB group of $0.56{\pm}0.06mg/mL$ in final. These results demonstrate that RGMB has effect of increasing immunity and practicable to use as feed additives on swine.
