  • Bats are an important reservoir of several zoonotic diseases. However, the circulation of bat coronaviruses (BatCoV) in live animal markets in Indonesia has not been reported. Genetic characterization of BatCoV was performed by sequencing partial RdRp genes. Real-time polymerase chain reaction based on nucleocapsid protein (N) gene and Enzyme-linked immunosorbent assay against the N protein were conducted to detect the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) viral RNA and antibody, respectively. We identified the presence of BatCoV on Cynopterus brachyotis, Macroglossus minimus, and Rousettus amplexicaudatus. The results showed that the BatCoV included in this study are from an unclassified coronavirus group. Notably, SARS-CoV-2 viral RNA and antibodies were not detected in the sampled bats.

  • Korea has passed the Act on the Integrated Control of Pollutant-Discharging Facilities in 2015, and the integrated environmental management under the BAT standard is underway. To summarize the nature of integrated environmental management, it is the regulation by the integration of the management of the multi-pollutant source and the technical standard of BATs. In general, in environmental economics, regulation-based on technical standards are known to be inefficient. This paper attempts to evaluate the efficiency of BAT standards from an economic point of view. A simple multi-pollutant model demonstrates that the inefficiency of the environmental tax with imperfect information in a single pollutant situation is amplified under multi-pollutant conditions. The simultaneous introduction of BAT and IPPC can be partially explained by this logic. It is also highlighted by the strengthening of BAT standards by EU, as a countermeasure to the potential deterioration of air quality caused by the change of effective environmental taxes accompanying the fuel and emission price changes.

  • As the public interest in environmental issues increased, the "Act On The Integrated Control Of Pollutant-Discharging Facility" was enacted. Through the integrated environmental pollution prevention act in which 19 industries with large environmental impacts are sequentially applied, pollutants can be managed in a medium-integrated manner and integrated permission of the business unit is possible and BAT can be applied to enable a scientific and proactive environmental management system. In addition, if the facility with BAT works normally, the pollutant emission is offered with the range of lower limit to upper limit. This study analyzed the overview of Best Available Techniques-Associated Emission Levels (BAT-AEL), and its setting procedure and method, and then suggested the BAT-AEL of a waste incineration facility. In comparative analysis on Emission Limit Values (ELVs) of EU, this study tries to propose improvement matters and development directions if the relevant standard is revised.

  • BAT (Best Available Technology economically achievable) assessment is indispensible to effective management policy of industrial wastewater discharging facilities such as setting effluent limitations guidelines for individual industry based on the wastewater characteristics and treatment efficiency, making effluent limitations guidelines for new sources, and calculation of the reducible amount of emission load conforming to a total emission general plan and enforcement plan. This study reviewed foreign cases of BAT assessment and condition of domestic wastewater discharging facilities, and suggested BAT assessment guideline suitable for the domestic conditions. The major assessment factors and flow are; (1) Identification of pollution source characteristics, (2) Identification and survey on technology, (3) Selection of candidate technology, (4) Assessment of legislation adaptation, (5) Assessment of environmental factor, (6) Assessment of economical acceptability, (7) Total weighting value factor assessment on technological factor, and (8) Total assessment and final BAT selection. The result of this study can be utilized as a major policy data and a base of industrial wastewater management system.

  • Background Brown adipose tissue (BAT) is a potential target for anti-obesity treatments. Previous studies have shown that BAT activation causes an acute metabolic boost and reduces adiposity. Furthermore, BAT and BAT-derived cell transplantation reportedly help treat obesity by regulating glucose and fatty acid metabolism. However, since BAT transplantation leads to whole-body weight loss, we speculated that earlier approaches cause a generalized and unnecessary fat tissue loss, including in breast and hip tissues. Methods We transplanted white adipose tissue-derived or BAT-derived preadipocytes prepared from C57BL/6 mice into one side of the inguinal fat pads of an obese mouse model (db/db mice) to examine whether it would cause fat loss at the peri-transplant site (n=5 each). The same volume of phosphate-buffered saline was injected as a control on the other side. Six weeks after transplantation, the inguinal fat pad was excised and weighed. We also measured the concentrations of glucose, triglycerides, fatty acids, and total cholesterol in the peripheral blood. Results BAT-derived preadipocytes showed abundant mitochondria and high levels of mitochondrial membrane uncoupling protein 1 expression, both in vivo and in vitro, with a remarkable reduction in weight of the inguinal fat pad after transplantation (0.17±0.12 g, P=0.043). Only free fatty acid levels tended to decrease in the BAT-transplanted group, but the difference was not significant (P=0.11). Conclusions Our results suggest that brown adipocytes drive fat degradation around the transplantation site. Thus, local transplantation of BAT-derived preadipocytes may be useful for treating obesity, as well as in cosmetic treatments.

  • In This paper, we propose a determine the correlation between bat swing speed and balance ability in elementary school baseball players. This study subjects were 40 subjects. Bat swing speed was measured using a zepp2baseball, and balance ability was measured using a biorescue. For the measurement of balance ability, eyes open surface·eyes open length·eyes open average speed·eyes close surface·eyes close length·eyes close average speed were measured. pearson's correlation analysis was used to analyze the correlation between bat swing speed and balance ability. There was a significant negative correlation between bat swing speed and eyes close surface (r=-0.366, p<0.05). There was a significant negative correlation between bat swing speed and eyes close length(r=-0.348, p<0.05). There was a significant negative correlation between bat swing speed and eyes close average speed(r=-0.455, p<0.01). Among them, eyes close average speed showed the highest correlation (p<0.01). These findings suggest that improvement of the balance ability has a positive effect on bat swing speed.

  • The Ussurian tube-nosed bat (Murina ussuriensis) is a registered endangered species that has not been observed in South Korea since 1960. We were able to capture three individuals of M. ussuriensis between 2011 and 2013 at Sobaeksan National Park. The discovery of this species was the first time within 50 years. To collect basic data on the M. ussuriensis, we analyzed the external morphology and ultrasound characteristics of the captured bats. The results indicated that M. ussuriensis weigh approximately 5.2 g, which is less than that of a typical small bat such as Pipistrellus abramus. The bat's wing-type ratio was determined to be 1.22 and classified as a broad and short wingspan type. The bat uses FM signals for ultrasound with a peak frequency of 92 kHz. The M. ussuriensis seems to be a forest-dwelling bat that preys on insects by maneuvering expertly within the complex mazelike structure of forests. In the future, further research on the hibernation and foraging sites of the bats is necessary to protect and monitor the species.

  • This thesis is focused on the bat symbol, especially prevalent crafts’ pattern in late Joseon period on museum collections. For the use and reperception of them, I am aimed for appropriate analysis of bat symbol by co connotation which reflects the characteristics on number.plastic.color symbol. This point of view, bat idea and bat paintings in Joseon period will be the source of meanings to the denotation of bat patterns. In the museum collections, bat paintings and patterns are calculated 324 objects. By functional classification, the bat patterns on dwelling-crafts for the royal and for the people will be discussed. In result, the bat paintings were only a few, however, usually connoted Taoist hermit with super-natural powers.longevity.protector of Lightning-God.praying for long life, which were based on Taoism. Meanwhile the bat symbol of dwelling-crafts for the royal projected the longevity and prosperity of king and queen. By he Five Blessings and good auspices in Ching dynasty, number of '5.4' implied 'Five Blessings', Through the correct recognition of homo-phone, "a bat(蝠, fu)=happiness(福, fu)$\rArr$five bats(五蝠)$\rArr$Five Blessings(五福 )." In the case of bat symbol on the dwelling-crafts for the people, especially its for women, it expressed on the metal-decoration of furniture and paper-crafts. In the metal-decoration, the signified of bat symbol were expellant-evil('guard') that of characteristic signifier, white-silver color, number '1' and 'flying-type'. The bat symbol on paper-crafts for the people signified 'double happiness'.harmony.sons with number of '2', 'Five Colors' and the transformation of 'flying-type'. Accordingly, the bat symbol on the dwelling-crafts for the people marked 'happiness and guard', because the people had concrete cognition the bat symbol as a denotation of 'happiness and 'guard' by itself
