The status and issues of the Institutional Animal Care and Use Committee of Seoul National University: from its establishment to the present day

The Institutional Animal Care and Use Committee (IACUC) of Seoul National University (SNU) plays a key role in monitoring and managing the humane use of animals in scientific research. Here, as one of the pioneers of the IACUC in Korea, we reported SNU-IACUC operations and activities including committee establishment and legal formulation, protocol review, and post-approval monitoring of protocols, which the IACUC has undertaken in the last decade. In addition, legal regulations and improvements were also discussed, and encompassed the limited number of committee members and the single IACUC policy in Korea. As of December, 2020, amendments are on the table at the National Assembly. We also emphasized the independent nature of the IACUC in protecting activities, including approval and monitoring animal experiments, and its public role in narrowing the knowledge gap between society and scientists. Thus, the aim of this report is to help society and scientists understand the operations of the SNU-IACUC and its role in animal welfare.

Assessing Effectiveness of a Nonhuman Animal Welfare Education Program for Primary School Children

Nonhuman animal welfare education aims to promote positive relationships between children and animals and thus improve animal welfare, yet few scientific evaluations of these programs exist. This study aimed to evaluate the effectiveness of an education program developed by the Scottish Society for the Prevention of Cruelty to Animals (SPCA) that included 4 interventions focusing on pets (companion animals), wild animals, farm animals, and general animal rescues. Knowledge, attachment to pets, and attitudes and beliefs about animal minds were assessed at pretest, posttest, and delayed posttest using a questionnaire administered to 1,217 Scottish children aged 7 to 13 years old. Results showed a significant positive impact of the program on knowledge about animals and the Scottish SPCA for all interventions. The pet and farming interventions significantly impacted children’s beliefs about animal minds. There were trends toward improvements in a range of other measures. This study highlights the importance of teaching animal welfare education to children for early prevention of animal cruelty, discusses the need to base this education on theory and research to find effective change, and demonstrates how evidence-based practice can inform future education programs.     

Cross-Sectional Study of Characteristics of Owners and Nonowners Surrendering Cats to Four Australian Animal Shelters

Unwanted cats surrendered to nonhuman animal shelters are generally categorized as either “owned” or “stray.” This classification is misleading because “stray” cats may include many “semiowned” cats, for which people provide care but who are not perceived as being owned. This differentiation is important because effective strategies designed to reduce cat admissions to, and euthanasia rates in, shelters rely on accurate information about cat populations contributing to shelter intake; cat semiowners will likely respond to different strategies than people with no relationship with the cats they surrender. People surrendering cats to four Australian animal shelters were surveyed to identify factors associated with perception of ownership. Many self-classified nonowners had fed the cats they surrendered, often for a considerable period of time. The factor most strongly associated with ownership perception was an increasing association time with the cat. These findings confirm that enduring relationships between surrenderers and cats, consistent with cat semiownership, are common for cats surrendered to Australian animal shelters. This finding should be taken into account when planning education messages and cat population management strategies aimed at reducing cat admissions.

The Indignity of Relative Concepts of Animal Dignity: A Qualitative Study of People Working with Nonhuman Animals

The Swiss animal welfare legislation is considered to be one of the strictest such laws worldwide. One unique feature is the inclusion of the concept of “dignity of the creature” and, more precisely, animal dignity. We interviewed 19 people from Switzerland and Germany about their concepts of animal dignity. Thereby, we investigated whether the very specific concept of the Swiss law is reflected in the minds of those who work with nonhuman animals on a daily basis. The results of our qualitative interviews revealed an awareness of the legal term among Swiss interviewees, but their personal concepts of animal dignity were not based on or similar to the legal definitions. The interviewed participants presented a broad range of concepts, including: similarities to human dignity, replacing concepts such as respect or integrity, and context-dependent, contingent forms of dignity. The applicability or usefulness of animal dignity was questioned by several participants; many judged it to be confusing or difficult. Therefore, we conclude by discussing animal integrity as an alternative concept that reflects the interviewees’ ideas of treating nonhuman animals in a respectful and appropriate way, and at the same time does not have the strongly metaphysical connotations of a concept such as human dignity.     

Animal Suffering: Representations and the Act of Looking

Animal advocacy uses images of nonhuman suffering as a form of normative rhetoric and a method of persuasion. Although much attention has been given to various facets of the depiction of human suffering, images of animal suffering have, to a large extent, escaped closer scrutiny. This paper seeks to remedy the situation by investigating four issues—the risk of aesthetics, the risk of perpetuating moral wrongs, the problem of privacy, and compassion fatigue—as they relate to images of farmed animal suffering. The paper will argue that images of nonhuman suffering are in danger of being interpreted as a form of visual intrigue, and that they invite seldom-asked questions concerning the justification of the act of looking, together with the privacy of nonhuman animals. Moreover, it will be maintained that compassion fatigue commonly affects how these images are perceived. Making use of the views of Susan Sontag, J. M. Coetzee, and Stanley Cohen (among others), it will be argued that, in order to escape the problematic connotations and consequences of the aforementioned issues, a normative dimension pointing toward action must be explicated.

Concentration and Composition of Serum and Plasma Glycosaminoglycans in Domestic Animal Species

Acid glycosaminoglycans (GAGs) were isolated from serum and/or plasma of some domestic animals and the composition of the isolated GAG mixtures were studied. Mean values of total GAG concentration, in terms of hexuronic acid, ranged from a maximum of about 12 mg/l in serum of calves, trained horses and sheep to about 9 mg/l in serum of cows and donkeys and in plasma of trained horses to about 6.5 mg/l in sedentary horse serum and rabbit plasma to a minimum of 4 mg/l in dog serum and sedentary horse plasma. Statistically significant differences in total GAG concentrations (P < 0.0005) were found in horses between plasma and serum and also between sedentary and trained subjects. Chondroitin sulphate was the main component in serum and plasma GAG mixtures, accounting for 81–84% of total GAGs in the examined animals, except in cow serum (72%), trained horse plasma (75.5%) and sheep serum (87%). Keratan sulphate-like structures, measured as galactose, ranged from 12% in sheep serum to 17% in cattle serum. Fucose was associated with galactose in GAG fractions, which supports the hypothesis that articular cartilage is among the sites of origin of circulating GAGs.     

Local advisers for the teaching of microbiology in schools

The purpose of this study was to examine the effect of formal teaching of ethical issues related to science on middle school students' attitudes towards science and science achievement. A total of 132 Grade 8 (age 13 – 14years) students in Seoul participated, who were divided into the control and the experimental group. Student attitude toward science was assessed using a questionnaire before and after the intervention which composed of five sub-categories: students' interest level in science, students' perception of the practicality of science knowledge, student's opinion on how science is defined, students' perception of the relationships within science, scientists and society, and students' perception of the value of science. The study further examined whether teaching ethical issues in science had any effect on students' achievement level by means of a pre- and post-test evaluation.

The results of this study showed that teaching ethical issues in science had a positive influence on the students' attitudes toward science, specifically, the interest level in science (p = 0.028) and perception of practicality of science knowledge (p = 0.044). However, there was no statistically significant difference in science achievement level between the control and experimental groups. The results imply that there is a need to explore ethical issues in science education, and that incorporating various materials on the ethical perspectives of science and technology in educational material will promote students' positive attitude towards science.     

动物存活率与平均寿命的数学关系

根据动物存活率与平均寿命的定义,推导出存活率与平均寿命的数学关系,即：E=-1lnr,其中E表示动物的平均寿命或期望寿命(可以用日、周、月、年等表示),r表示特定时段内(可以用日、周、月、年等表示)动物的平均存活率,其时间单位与E相对应．根据这种关系,可以利用动物的平均存活率估计其平均寿命(或期望寿命),反之,如果已知动物的平均寿命,也可以用来推算动物的平均存活率．
