  • The habitat characteristics and feeding ecology of the Siberian stone loach Barbatula toni were investigated in Bukcheon (Stream), Eocheonri, Ganseong-eup, Goseong-gun, and Gangwon-do, Korea from January to December 2013. B. toni lived in rapids or slow rapids from the upper stream to downstream, with the largest number of inhabitants in the middle-downstream regions. As a result of analyzing habitat preferences by age, 0+ and 1+ to ≥3+ showed differences. Ages of 0+(juveniles) lived mainly in rapidly flowing water (37.6±26.79 cm/sec) and low water depths (13.3±9.47 cm) in the pebble bottoms (substratum particle size 9.5±6.66 cm), but ages 1+ to ≥3+ lived mainly in relatively slowly flowing water (13.3±17.33 cm/sec) and relatively deep depths (25.9±10.31 cm) in stone and large stone bottoms (substratum particle size 18.0±7.63 cm). B. toni was mainly eaten from March to December when the temperature was above 5℃, and the amount of food eaten peaked in June and October. Their main food sources analyzed by the index of relative importance (IRI) included Diptera (57.0%), Ephemeroptera (29.3%), and Trichoptera (13.5%). The juveniles (age 0+) fed on small-sized prey such as Diptera and Trichoptera whales, but as they grew, they mainly ate large-sized Ephemeroptera. These feeding habits and changes in food according to the growth of B. toni were very similar to those of sibling species, B. nuda.

  • This essay examines Toni Morrison's African-American characters' struggle in The Bluest Eye (1970) and Home (2012) through the lens of heteronormativity, arguing that they suffer double victimization due to both their race and gender. The Bluest Eye portrays a family tragedy caused by an African-American husband and wife's failure to live up to images of gender as represented in white, middle-class media. Written forty-two years later, Home describes an African-American man and woman who establish their own lives away from gendered standards after striving to meet social expectations and becoming traumatized in the process. Their adversities stem not only from the deeply rooted racial discrimination in American society but also from subtle gendered norms implanted by heteronormativity. Morrison's characters in her earlier narrative face a tragic denouement, ultimately destroying their children's lives. By contrast, Morrison's later characters explore more utopian ways of life unfettered by heteronormativity, overcoming hardships imposed by white-centered heteronormal society. By portraying socially victimized characters, Toni Morrison problematizes the power behind the discriminatory nature of heteronormativity and suggests a more gender-neutral, egalitarian way of organizing society, free from the constraints of heterosexuality and from violence created by normalized gender rules.

  • Life history of the Siberian stone loach, Orthrias toni, were investigated using samples collected from Buk Stream, Goseong-gun, Gangwon-do, Korea. Growth was rapid between April and October when water temperature exceeded $10^{\circ}C$, but growth almost stopped from November-March when water temperature was below $10^{\circ}C$. Age groups for O. toni estimated by frequency distribution of total length in spawning season (May) indicated the 60~81 mm is 1-year old, the 82~99 mm group is 2-years old, the 100~119 mm is 3-years old, and the 120~140 mm is more than 4-years old. Total length range by sex was similar, and sex ratio (♂/♀) was 0.73. Spawning season according to the gonadosomatic index (GSI) was May with water temperature $14{\sim}17^{\circ}C$, and almost all fish were mature after one year old. Fecundity increased rapidly with age with an average of $4,460{\pm}3,302$ ($mean{\pm}SD$). Size of mature eggs was $0.87{\pm}0.03mm$ in diameter irrespective of age.

  • The purpose of this paper is to investigate the attitudes and practices of life demanded for authentic existence in adversity, focusing on Toni Morrison's Home which was published in 2012. Home portrays the journey of Frank Money, an African-American veteran of the Korean War who strives to extricate his sister Cee from inhumane violence. Through this work, Morrison criticizes prevalent racism in the 1950s which is regarded as a time of affluence and peace through this sibling's agony. In this paper, firstly I attempt to examine the aspects of racism which Frank and Cee face and their distorted survival strategies. Secondly I try to find the right direction of brother and sister relationship based on Frank and Cee who are compared to Hansel and Gretel. Thirdly I try to point out the importance of self-reflection required for the healing process of Frank and Cee who overcome adversity and restore their identity with the help of Samaritans. And I investigate the possibility of ethical practice going beyond my family to strangers.

  • The ultrastructure of the spermatozoa of the family Cobitidae, 6 genera and 12 species, was examinated under electron microscopes. Spermatozoa of the observed species consist of a head(nucleus), a short midpiece, and a single tai1(flagellum). It is of anacrosomal aquasperm type, lacking an acrosome. However, the spermatozoa of Nemacheilus toni has vestigal acrosome or acrosome-like vesicle in the anterior region of the nucleus during spermiogenesis, The nucleus of Cobitidae is approximately spherical except that N. toni is conic. The mid piece was under $3.0{\mu}m$ in length and contained 5-8 ring-shaped mitochodria. Genera Cobitis, Iksookimia, Niwaella, and Nemacheilus. have shorter midpiece, whereas Misgurnus and Lefua have longer midpiece. The flagellum was uniflagellate consisting of a typical 9+2 axoneme without fins.

  • Two stone loaches (Nemacheilidae, Cypriniformes), Barbatula toni (Dybowski, 1869) and B. nuda (Bleeker, 1864), have been recognized in the Korean waters to date. Recently, due to indiscriminate artificial introduction as well as the change of their habitats induced by natural disasters, it seems to be concerned about the damage of species-specific geographic boundaries. We examined the genetic difference of two Korean Barbatula species by the haplotype network based on the Cytochrome b sequences of mitochondrial DNA and the phylogenetic relationships among them including Barbatula fishes occurring around the Korean peninsula. As a result, three and 29 haplotypes were obtained from B. toni and B. nuda, respectively, and totally three clades comprising "toni group", "nuda hangang group", and "nuda donghae group" were identified. The sequence variable sites among them was 10~24%, showing a difference of interspecific level. Phylogenetic relationships of the latter group, especially, forms an independent cluster discriminating with other two groups as well as the Chinese, Japanese, Russian, and European Barbatula species, suggesting the possibility of the specific level divergence.

  • This paper tries to follow Toni Morrison's postcolonial courses in her novels. In The Bluest Eye, Morrison examines the situation in which the white's values are the standard for the whole society through two little black girls, Pecola and Claudia. In Song of Solomon she recommends emulating Pilate's love and good attitude towards tradition to shape a positive identity for Afro-Americans, which Milkman comes to accept. In Tar Baby, Morrison suggests that Son's and Jadine's ideas, traditional and modern, should be combined. In Beloved, Morrison illustrates one of the ways in which all blacks can escape from their own trauma through Sethe's process of finding her self-worth. In Paradise Morrison shows that the real de-colonial way to overcome the effects of colonization is to create a new paradigm in which everyone is respected regardless of race. In her works, Morrison insists that by remembering and regretting slavery in America, people can overcome its aftereffects and trauma. Racial oppression still exists today, so Morrison will continue her beautiful, powerful and eye-opening work.
