The occurrence of PZ-peptidase in Streptococcus sanguis and other oral bacteria was investigated utilizing washed whole cells as the enzyme source and PZ-pentapeptide as its substrate. Under the culture conditions employed in the present study. Streptococcus sanguis strains, fresh isolates as well as laboratory strains, produced a broad range of the enzyme activity (0.5-7.9 unit/mg protein). The strains of both Streptococcus mutans and Lactobacilli showed low levels of activity (0-0.5 unit/mg protein for S. mutans). As compared with the enzyme activities of other bacteria, a moderate range of activity was produced by the strains of Strptococcus mitis nad Strptoccus salivarius. Actinomyces strains, like those of S. sanguis, produced a varying amount of activity (0-9.8 unit/ mg protein). A possible involvement of the oral bacterial PZ-peptidase in the metabolism of human saliva proteins is discussed.

This study analyzed the influence of other customers' perception (similarity, physical attraction, and suitable behavior) of the fashion retail environment on male customers' store attitude and behavioral response. In addition, comparing the effect of store type, this study comprehensively provides the effect of other customers' perception in fashion retailing. In order to investigate research questions, an online survey was conducted and 220 responses were analyzed using AMOS 18.0. The results of this research were as follow. First, the dimensions of physical attraction and suitable behavior of other customers influenced toward target customer's fashion store attitude. Second, the effect of store attitude towards the perceiver's behavioral response was proven. Third, customers established their store attitude by other customers' physical attraction in luxury stores, while others' behavior was meaningful in SPA store. Fourth, other customer's similarity dimension did not influence the male customers' store attitude. This study contributes to a comprehensive understanding of other customer's effect in fashion stores by examining different store types. In addition, managers may establish a customer portfolio strategy and training based on this research.

This essay explores how Leslie Marmon Silko's Ceremony and Storyteller encourage human's sympathetic relationship with the nonhuman animal-Other, paying attention to her posthumanist voices against anthropocentric mistreatment of animals which is inseparable from white Americans' environmental and racio-ethnic subjugation of nature and Natives in the colonialist history of the United States. As a way of dissolving the problematic anthropocentrism and embracing the animal-Other as a fellow creature, Silko employs and transforms Native American oral tradition in her own idiosyncratic posthumanist storytelling. In order to highlight the ethico-political examination of the animal issue in her storytelling, this essay refers to contemporary posthumanist thinkers such as Jacques Derrida, Giorgio Agamben, and Gilles Deleuze who are all in their own ways critically engaged with Western metaphysical anthropocentrism. Arguably, in a similar vein with the posthumanist critics, Silko disrupts the mischievous hierarchical opposition of humans/animals that have directly or obliquely warranted violence against the animal-Other. In order to demonstrate Silko's ethico-politicality concerning the animal issue, this essay inquires her critical perception of humans' misunderstanding (or misbehavior) toward animals in terms of the suffering and death of animals. Besides, Silko's posthumanist storytelling of the animal's gaze (as Derrida notes as an event of revealing human aporia and vulnerability) and "in-between" (as a reification of crossing the boundary of humans/animals) is discussed with the exemplification of Tayo's encounter with a mountain lion and a bear-man Shush. The posthumanist approach to thinking about the animal-Other in Ceremony and Storyteller would shed light on the ethico-political significances of Silko's storytelling in our time in peril of losing the tie between humans and nonhuman animals.

Solanum hougasii, one of the wild Solanum species, has been widely used in potato breeding since it exhibits excellent resistance to diverse important pathogens. S. hougasii can be directly crossed with the cultivated tetraploid potato (S. tuberosum) owing to its EBN (Endosperm Balanced Number) value of 4, which is same as that of S. tuberosum although it is an allohexaploid. In this study, the complete chloroplast genome sequence of S. hougasii was obtained by next-generation sequencing technology, and compared with that of the chloroplast genome of seven other Solanum species to identify S. hougasii-specific PCR markers. The length of the complete chloroplast genome of S. hougasii was 155,549 bp. The structural organization of the chloroplast genome in S. hougasii was found to be similar to that of seven other Solanum species studied. Phylogenetic analysis of S. hougasii with ten other Solanaceae family members revealed that S. hougasii was most closely related to S. stoloniferum, followed by S. berthaultii, and S. tuberosum. Additional comparison of the chloroplast genome sequence with that of five other Solanum species revealed five InDels and 43 SNPs specific to S. hougasii. Based on these SNPs, four PCR-based markers were developed for the differentiation of S. hougasii from other Solanum species. The results obtained in this study will aid in exploring the evolutionary and breeding aspects of Solanum species.

Solanum demissum is one of the wild Solanum species originating from Mexico. It has wildly been used for potato breeding due to its resistance to Phytophthora infestans. S. demissum has an EBN value of four, which is same as that of S. tuberosum, so that it is directly crossable for breeding purposes with the cultivated tetraploid potato (S. tuberosum). In this study, the chloroplast genome sequence of S. demissum obtained by next-generation sequencing technology was described and compared with those of seven other Solanum species to develop S. demissum-specific markers. Thetotal sequence length of the chloroplast genome is 155,558 bp, and its structural organization is similar to those of other Solanum species. Phylogenetic analysis with ten other Solanaceae species revealed that S. demissum is most closely grouped with S. hougasii and S. stoloniferum followed by S. berthaultii and S. tuberosum. Additional comparison of the chloroplast genome sequence with those of seven other Solanum species revealed two InDels specific to S. demissum. Based on these InDels, two PCR-based markers for discriminating S. demissum from other Solanum species were developed. The results obtained in this study will provide an opportunity to investigate more detailed evolutionary and breeding aspects in Solanum species.

The tetraploid Solanum hjertingii, a wild tuber-bearing species from Mexico is a relative of potato, S. tuberosum. The species has been identified as a potential source of resistance to blackening for potato breeding. It does not exhibit enzymatic browning nor blackspot which are physiological disorders. However, due to their sexual incompatibility, somatic hybridization between S. hjertingii and S. tuberosum must be used to introduce various traits from this wild species into potato. After somatic hybridization, molecular markers are essential for selecting fusion products. In this study, the chloroplast genome of S. hjertingii was sequenced by next-generation sequencing technology and compared with those of other Solanum species to develop specific markers for S. hjertingii. The chloroplast genome has a total sequence length of 155,545 bp, and its size, gene content, order and orientation are similar to those of the other Solanum species. Phylogenic analysis including 15 other Solanaceae species grouped S. hjertingii with S. demissum, S. hougasii, and S. stoloniferum. After detailed comparisons of the chloroplast genome sequence with eight other Solanum species, we identified one InDel and seven SNPs specific to S. hjertingii. Based on these, five PCR-based markers were developed for discriminating S. hjertingii from other Solanum species. The results obtained in this study will aid in exploring the evolutionary aspects of Solanum species and accelerating breeding using S. hjertingii.

Air pollution problems are serious and present significant challenges to the engineering research community. EPA's engineering research programs have shifted from a primary focus on $SO_2$ and NOx pollution control to more complex and more difficult problems such as indoor air quality, air toxics, and global climate change. EPA research engineers are working closely with other research organizations in both the private sector and other federal research organizations to identify, evaluate, and develop cost-effective engineering solutions. The APPCE works closely with the EPA regulatory and regional offices to ensure that the best engineering information is utilized to formulate and implement the Agency's environmental protection program.
