Analysing companion species from unrelated taxa concentrated so far mainly on identifying biosurrogacy in terms of conservation biology. No study has investigated companion bird and plant species to predict breeding and migrant habitats of a bird genus. In this study we recorded and analysed companion bird and plant species of the breeding bird Cyprus Wheatear Oenanthe cypriaca and four migranting Oenanthe species on Cyprus. We found characteristic companion species in Cyprus Wheatear's, Wheatear migrant's and in control habitats where no Wheatears were present. We show that plant and bird companion species can be used as discriminating factors to predict breeding and migrant habitats of the genus Oenanthe on Cyprus. Furthermore, habitat preferences of Cyprus Wheatear's companion species indicate bushy and vegetation rich habitats avoiding woodland on the one hand and managed farmland on the other hand. In comparison, migrant Wheatear and control habitats were characterised by companion species pointing to a high openness. These results support former habitat descriptions of Cyprus Wheatear and migrant Wheatears. In more general, this study shows that companion species from unrelated taxa can be used to predict breeding and migrant habitats of a bird genus.

Currently, many households raise their companion animals for personal reasons. In this environment, the companion animal is left alone in the home, the owner of the companion animal is increasingly curious about the behavior pattern of the companion animal left alone, and there are many devices that can solve this question. In this paper, we have designed and implemented a Bluetooth-based slave device (beacon in this paper) and a router capable of connecting to a broadband network that can observe behavior patterns of companion animals by using advanced ICT technology. The Bluetooth router designed and implemented in this paper installs a beacon in the home, receives the beacon signal from the device and the beacon installed by the companion animal, and transmits the moving line of the companion animal to the owner of the companion animal through the broadband network, so that it can be confirmed in real time through the app for the provided smart phone.

Continuous cropping obstacles have become a serious factor restricting sustainable development in modern agriculture, while companion planting is one of the most common and effective methods for solving this problem. Here, we monitored the effects of companion planting on soil fertility and the microbial community distribution pattern in pepper monoculture and companion plantings. Soil microbial communities were analyzed using high-throughput sequencing technology. Companion plants included garlic (T1), oat (T2), cabbage (T3), celery (T4), and white clover (T5). The results showed that compared with the monoculture system, companion planting significantly increased the activities of soil urease (except for T5) and sucrase, but decreased catalase activity. In addition, T2 significantly improved microbial diversity (Shannon index) while T1 resulted in a decrease of bacterial OTUs and an increase of fungal OTUs. Companion planting also significantly changed soil microbial community structures and compositions. Correlation analysis showed that soil enzyme activities were closely correlated with bacterial and fungal community structures. Moreover, the companion system weakened the complexity of microbial networks. These findings indicated that companion plants can provide nutrition to microbes and weaken the competition among them, which offers a theoretical basis and data for further research into methods for reducing continuous cropping obstacles in agriculture.

The objective of this study were to assess rooftop urban agriculture and analyze the differences in soil, growth, physiology, and productivity to elucidate the effect of companion planting with various plants, including lettuce (Lactuca sativa), rosemary (Salvia rosmarinus), marigold (Tagetes patula), Korean perilla (Perilla frutescens), and garlic chives (Allium senescens). Measurements were taken every other week from May to August 2023, totaling eight measurement. Regarding the characteristics of the soil planted with lettuce and aromatic plants, the combined planting of lettuce and garlic chives created a favorable soil environment for plant growth. Consequently, the best growth was observed when lettuce and garlic chives were companion planted. Companion planting of lettuce and garlic chives appears to be the most efficient concerning growth and physiology. The productivity of companion planting lettuce and aromatic plants also showed high-quality lettuce when lettuces and garlic chives were companion planted. Therefore, companion planting of lettuces and garlic chives in rooftop urban agriculture is suitable for growth, physiology, and productivity.

The aim of this article is to argue that BanLyeo music (companion music) is much better than medicine. A companion who shares thoughts or actions, or a metaphorical description of an object that is always close or carried. Isn't the music that we share in our daily lives a BanLyeo music (companion music)? Music stays with us forever as long as we choose. Therefore, it is music that can go with us until the end, so I think we should call it BanLyeo music (companion music). Music can be with us whenever and wherever we want, soothing sadness and pain and cheering us up. Here is a person who is living a second life happily because of BanLyeo music. Beyond the passive listening to music, direct and active music performance is a great power to save one person. As a more effective healing agent than medicine, BanLyeo music is a great power to stay together for the rest of your life and cheer you up. So, I think music is much better than medicine.

Currently, various probiotics are being used to improve the nutrition of companion animals. They are widely sold as additives in companion animal foods because of the numerous gastrointestinal and immune health benefits for dogs and cats. Therefore, extensive research is being conducted to improve quality and safety during manufacturing and to extend the shelf life of companion animal foods by adding probiotics. The manufacturing process must be conducted such that the characteristics and efficacy of probiotics added to food are optimally beneficial for companion animals. Therefore, this review aims to address the overall characteristics of the probiotic strains used and to examine the various methods through which probiotics are added to companion animal foods.

Rabies virus (family Rhabdoviridae, genus Lyssavirus, RV) is the causative agent of rabies in mammals. We conducted a sero-epidemiological survey for RV using sera from South Korean stray and companion dogs in the present study. A total of 533 canine serum samples were collected between February 2006 and December 2007 and were screened for rabies immunity with a neutralizing peroxidase linked assay. Both companion (49.1%) and stray (60.1%) dogs demonstrated RV seropositivity. Regional RV antibody prevalence was measured in the Jeju (87.5%), Gyeonggi (62%), Gyeongsang (59.1%), Jeonra (42%), Chungcheong (37.9%), and Gangwon (30.4%) provinces. Prevalence increased with age but did not exceed 80% in any age group. Stray and companion dogs had RV antibody prevalence values of 26.7% and 23.7%, respectively. Seroprevalence was significantly associated with age $({\chi}2\;=\;9.46;\;p\;=\;0.024)$ for companion dogs, although this association was not evident in stray dogs. There were no significant differences in age between stray and companion dogs and no gender differences in RV seroprevalence. Our results suggested that a widespread and reinforced vaccination program must be applied to Korean dogs.

Cancer treatment has been stratified by companion biomarker tests that serve to provide information on the genetic status of cancer patients and to identify patients who can be expected to respond to a given treatment. This stratification guarantees better efficiency and safety during treatment. Cancer patients, however, marginally benefit from the current companion biomarker-aided treatment regimens, presumably because companion biomarker tests are dependent solely on the mutation status of several genes status quo. In the true sense of the term, "personalized medicine", cancer patients are deemed to be identified individually by their molecular signatures, which are not necessarily confined to genetic mutations. Glycosylation is tremendously dynamic and shows alterations in cancer. Evidence is accumulating that aberrant glycosylation contributes to the development and progression of cancer, holding the promise for use of glycosylation status as a companion biomarker in cancer treatment. There are, however, several challenges derived from the lack of a reliable detection system for aberrant glycosylation, and a limited library of aberrant glycosylation. The challenges should be addressed if glycosylation status is to be used as a companion biomarker in cancer treatment and contribute to the fulfillment of personalized medicine.
