Background: In modern society, the number of households raising companion animals increases, and the market for veterinary medicines is expanding even more. This study aims to investigate the perception of companion animal lovers' veterinary medicines, the necessity of specific guidance by pharmacists for veterinary medicines, the role of pharmacists at veterinary pharmacies, and ways to fulfill that role. Methods: This study evaluated veterinary medicines and medication guidance through Google online questionnaire targeting pet-lovers from December 20, 2021, until January 19, 2022. The questions consist of 1) characteristics of petlovers, 2) purchase history and drug recognition of veterinary drugs, 3) use of veterinary vaccines, 4) use of diagnostic kits, and 5) guidance of veterinary medicines by local pharmacists. Results: The respondents' experience purchasing veterinary drugs was as high as 94.4%. The most purchased drug was heartworm-preventing products, and vaccination was performed mainly at veterinary clinics (veterinarians). The respondents primarily purchased veterinary medicines for companion animals at veterinary hospitals and did not know the name of the drugs which they bought. In addition, respondents expected to receive specific information on veterinary medicines from pharmacists. Conclusion: As the number of veterinary pharmacies in the community will increase with the expansion of the companion animal market, pharmacists should play their role as experts in veterinary medicines through systematic and continuous professional education.

This paper provokes considerations on companionship. As human-robot relation becomes important, the role and communication styles of robot become crucial. In order to see how we should design communication styles of social robots, we generated scenarios based on pre-studies. Then, we conducted a $2{\times}2$ experiment to compare four different conditions by expected role and communication style. We divided expected roles into playing and serving role by dominance level. Also, we matched communication style on one condition and mismatched on the other. The results imply matching role with communication style is crucial in some role, however not in every role. As HCI expands to human-computer relation, our study would inspire future research on companionship between human and robots.

The purpose of this study is to understand the recognition of pet dogs between companion animal majors and non-majors regarding preference, knowledge, competence, role, image, use of pet dogs. A survey was conducted among 164 high school and college, university students from rural areas, medium and large cities, comprised of both companion animal majors and non-majors. The collected data was processed with $X^2$-test to see statistical significance between the two groups. The result showed a significance of (p<0.05) in competence as companion and working dogs and in Animal-Assisted Therapy for physically and psychologically challenged patients. Also, there was a great gap between two groups in recognizing pets and companion animals. Therefore, it is required to develop and implement policy programs that expand people's understanding on roles and competence of companion animals so that they can be identified as a real life companion beyond pets.

To evaluate the estrogenic activities of di-ethyl hexyl phthalate (DEHP) and di-butyl phthalate (DBP), two phthalates known as endocrine disrupters, we used MCF-7 human breast cancer cell line. As results, DBP and DEHP had estrogenic effects. In brief, the concentration of maximal MCF-7 cell proliferation was $10^{-7}M\;and\;10^{-8}M$ for DEHP and DBP, respectively. The ratio of maximal cell yield of the test compounds to that of $17{\beta}-estradiol$ was 87.5% for DEHP and 73.4% for DBP. In summary, both DEHP and DBP had cell proliferation potencies in the MCF-7 cell. Potencies ranged from approximately 10 to 100 times less than 17beta-estradiol. DBP was stronger than DEHP in the concentration of maximal efficacy. However, DEHP was stronger than DBP in the MCF-7 cell proliferation. Results from this study suggested that DEHP and DBP may play an important role in the estrogenic activity. Therefore, it is suggested that DEHP and DBP are estrogenic.

Purpose : The purpose of this study was to evaluate the factors which are related to the maternal role performance of first-time mother to improve the health of infant. Specifically a basic hypothetical model was developed based on the previous study about a model of social networks. Method : The survey was done from January to February in 2001. Total 257 mothers who have four to twelve month old first-time baby was interviewed in five community health center around country(Seoul, Choung-ju, Asan, Cheon-an, Jeju). Finally 247 data was analyzed. Data analysis was done with LISREL 8.20 program for covariance structural analysis. Results : Compared to the hypothetical model, the revised model has become parsimonious and had a better fit to the data ($X^2=167.55$ (p값=.00), $x^2/df=1.48$, GFI=0.97, AGFI=0.95, RMR=0.049, NFI=0.98, NNFI=0.99, CN=222.53). All predictive variables of the maternal role of first-time mother explained 30% of total variance in model. Social network structural characteristics and social network interactional characteristics had significant effect on the emotional support and the information support. And social network interactional characteristics had significant effect on the service support, material support and social companionship support. The service support and social companion ship support had significant effect on the maternal role strain. The emotional support and the social companion ship support had significant effect on the maternal role of first-time mother. Conclusion : As the conclusion of this study, there is in need of the developing the programmes focussed on the social network for the first-time mother.

We use N-body/hydrodynamic simulations to study the evolution of the spin of a Milky Way-like galaxy through interactions. We perform a controlled experiment of co-planar galaxy-galaxy encounters and study the evolution of disk spins of interacting galaxies. Specifically, we consider cases where the late-type target galaxy encounters an equally massive companion galaxy, which has either a late or an early-type morphology, with a closest approach distance of about 50 kpc, in prograde or retrograde sense. By examining the time change of the circular velocity of the disk material of the target galaxy from each case, we find that the target galaxy tends to lose the spin through prograde collisions but hardly through retrograde collisions, regardless of the companion galaxy type. The decrease of the spin results mainly from the deflection of the orbit of the disk material by tidal disruption. Although there is some disk material which gains the circular velocity through hydrodynamic as well as gravitational interactions or by transferring material from the companion galaxy, it turns out that the amount of the material is generally insufficient to increase the overall galactic spin under the conditions we set. We find that the spin angular momentum of the target galaxy disk decreases by 15-20% after a prograde collision. We conclude that the accumulated effects of galaxy-galaxy interactions will play an important role in determining the total angular momentum of late-type galaxies.

In this paper, we describe CAMAR Companoin, a context-aware mobile AR system that provides a user-adaptive assistance with an augmented picture according to the user's context in smart space. It recognizes physical objects and tracks the movement of those objects with a camera embodied to a mobile device. CAMAR Companion observes a mobile user's context, which is sensed by various kinds of sensors in environments, and infers user preference for the content in the situation. It recommends multimedia content relevant to the user's context. It overlays selected content over associated physical objects and enables the user to experience the content in a user-centric manner. Furthermore, we have developed the prototype to illustrate how our system could be used for a mobile user's well-being care applications in smart home environments. In this application, we found that our system could perceive a user preference even though a user's context is changed dynamically, and then adapt the multimedia content with respect to the user's context effectively. As such, the proposed user-adaptive system has the potential to play an important role in developing customized user interfaces in mobile devices.

Permanent deformation plays a key role in performance based earthquake resistant design. In order to estimate permanent deformation after earthquake, it is essential to secure reliable response history analysis(RHA) as well as earthquake scenario. This study focuses on permanent deformation of an inverted T-type wall under earthquake. The study is composed of two separate parts. The first one is on the verification of RHA and the second one is on an effect of input earthquake motion. The former is discussed in this paper and the latter in the companion paper. The verification is conducted via geotechnical dynamic centrifuge test in prototype scale. Response of wall stem, ground motions behind the wall obtained from RHA matched pretty well with physical test performed under centrifugal acceleration of 50g. The rigorously verified RHA is used for parametric study to investigate an effect of input earthquake motion selection in the companion paper.

Children team about their roles through literature, receive the information about the roles of family members and come to accept them. Especially, father's roles in biographies are so diverse, not consistent, compared to mother's roles, that it world be judged to be difficult for the children who had read to form the concept of the father's roles. As the father's roles in the fairy tales have important effect upon the formation of the children's role concept toward their fathers, the purpose of this study is to investigate the father' role appeared in Korean biographies. The method used for this study is the content analysis of the context related with fathering in Korean biographies. It is found that the most frequent father' role appeared in Korean biographies was a friend and companion such as to talk with child about the child's future. And the second frequent father's role in Korean biographies was a family ancestor, such as, to pray for a son's birth, to name the child, to arrange the child's marriage. The third role was that of a loaming helper. These results have been discussed in the light of former studies, and the limits of study method also have been discussed.

As the number of households that raise dogs and cats is increasing, there is growing interest in animal health. The gut plays an important role in animal health. In particular, the microbiome in the gut is known to affect both the absorption and metabolism of nutrients and the protective functions of the host. Using probiotics on pets has beneficial effects, such as modulating the immune system, helping to reduce stress, protecting against pathogenic bacteria and developing growth performance. The goals of this review are to summarize the relationship between probiotics/the gut microbiome and animal health, to feature technology used for identifying the diversity of microbiota composition of canine and feline microbiota, and to discuss recent reports on probiotics in canines and felines and the safety issues associated with probiotics and the gut microbiome in companion animals.
