  • Objective: Recently, there has been an increasing interest in conservation of native genetic resources of chicken on a worldwide basis. Most of the native chicken breeds are threatened by extinction or crossing with ecotypes. Methods: Six Saudi native chicken breeds including black naked neck, brown frizzled, black, black barred, brown and gray were used in the current study. The aim of the current study was to evaluate genetic diversity, relationship and population structure of Saudi native chicken breeds based on 20 microsatellite markers. Results: A total of 172 alleles were detected in Saudi native chicken breeds across all 20 microsatellite loci. The mean number of alleles per breed ranged from 4.35 in gray breed to 5.45 in normally feathered black with an average of 8.6 alleles. All breeds were characterized by a high degree of genetic diversity, with the lowest heterozygosity found in the brown breed (72%) and the greatest in the frizzled and black barred populations (78%). Higher estimate of expected heterozygosity (0.68) was found in both black breeds (normal and naked neck) compared to the other chicken populations. All studied breeds showed no inbreeding within breed (negative inbreeding coefficient [$F_{IS}$]). The phylogenetic relationships of chickens were examined using neighbor-joining trees constructed at the level of breeds and individual samples. The neighbor-joining tree constructed at breed level revealed three main clusters, with naked neck and gray breeds in one cluster, and brown and frizzled in the second cluster leaving black barred in a separate one. Conclusion: It could be concluded that the genetic information derived from the current study can be used as a guide for genetic improvement and conservation in further breeding programs. Our findings indicate that the Saudi native chicken populations have a rich genetic diversity and show a high polymorphism.

Between Man and Animal: Figuration of Animals in Children's Literature Focused on The Wind in the Willows (인간과 동물 사이 -아동문학의 동물 형상화 『버드나무 사이로 부는 바람』을 중심으로)

  • In "The Animal That Therefore I Am (More to Follow)," Derrida notices that he is being watched by his cat. He becomes ashamed of being naked in front of his cat. The sense of shame is a response to being reduced to the level of an animal. He is ashamed of being as naked as an animal. His next move is, therefore, to cover his nakedness from the gaze of his cat. By contrast, he realizes, the animal is not self-conscious of being naked and so does not shield its nudity. In a truer sense, then, the cat is not naked. Humans do not see animals for what they really are but what they project on them. Whereas the gap between man and animal is clearly identified by Derrida's philosophical discourse, the possibility of going beyond the gap can be suggested by fantasy stories in children's literature. Children's literature in Britain arose in the eighteenth century with the revival of traditional fairy tales and growth of literary fairy tales. Romanticism in the early nineteenth century contributed to opening up a new horizon for the concept of the child, in which the child is no longer defined as the object to be tamed and childhood imagination is glorified as a powerful means to reach the higher state, the spiritual origin prior to separation of Man from the 'thing-in-itself.' In The Wind in the Willows, animals talk and behave like humans. The anthropomorphic figuration of animals can be understood as a result of the one-sided projection of anthropocentric perspectives on animals rather than an interaction between humans and animals. Significant contradictions also emerge in this story, however, as traits particular to animals are vividly delineated even as the main didactic theme of good triumphing over evil reflects an anthropocentric projection on animals. An attempt to capture the true characteristics of animals and locate them in the text constitutes a remarkable achievement in The Wind in the Willows. This can be evaluated as an important step toward a more ecopocentric perspective on animals which appears in later children's fantasies like Charlotte's Web.

  • In an attempt to develop composite flours based on raw materials available in Korea, six domestic resources were investigated with respect to their physical and chemical properties, nutritive value and economy. The results are summarized as follows: 1) Flours from naked barley, sweet potato, potato, corn, defatted rice bran and defatted soybean were compared in respect of their proximate composition, thiamine content and protein score. 2) In color comparison, naked barley and defatted soy flours were comparable to wheat flour whereas corn and sweet potato flours were a little inferior. In raising power, naked barley and defatted soy flours were similar to wheat flour and others were inferior. 3) In maximum viscosity of flours by amylograph, naked barley, corn and potato flours were higher than wheat flour and others were lower. In viscosity in cooling, corn flour was similar to wheat flour and naked barley and potato flours were lower. Addition of $10{\sim}20%$ defatted soy flour into other flours generally caused the lowering of viscosity. Addition of emulsifiers such as glyceryl monostearate, calcium stearyl lactylate, Methocel and Emulthin into the flours manifested different effects on the amylogram. 4) In nutritional test by rat, diets consisting of naked barley, sweet potato, potato or corn flours, each containing defatted soy flour (at 10% level with exception of 20% for sweet potato flour) and naked barley flour fortified with lysine were similar to wheat flour in digestibility, but were superior in NPU and biological value. 5) In price estimation, sweet potato and corn flours were competitive with wheat flour, but naked barley flour was a little expensive. On the other hand, barley and sweet potato are promising in terms of domestic production.

  • In order to investigate the heading responses of naked barleys and their grain yields under the different sowing times in spring sowing at 9 levels and to select the promising variety, present work was carried out with 11 recommended naked barley varieties and 2 newly developed lines for the period of 3 years from 1971 to 1973 at Iri, these results being summarized as follows: 1. Under spring sowing cultures, 'Wanju naked barley' being spring habit showed the highest yields among them. However, Sedohadaka and Bangju being winter habit were also considered as the promising varieties. 2. In the case of sowing the spring type naked barleys in spring the optimum sowing time of barleys at Iri was estimated in the late of February or the early of March. 3. The number of main culm leaves and tillering per hill of 'Wanju naked barley' were not influenced at sowing times. But winter type barleys being sown in spring, they were outstandingly increased in accordance with the sowing time being late, especially after the critical sowing time. 4. In comparison with average days from germinating to heading date under different seasonal sowing at the same variety, 'Wanju naked barley' took 64.4 days to get heading and Kikaihadaka and Hyangchoen gwa, the low spring growing habit varieties, 72-73 days. 5. Young spikelet differentiation stage (length of young spikelet: 0.3-0.5mm) arrived at about 30 days before heading date in comfortable sowing time without regarding spring or winter type. But number of main culms disclosed great differences among them; barleys being high spring type were 4 leaves and low about 6. 6. In the view of morphology, culm length under the different seasonal sowing could not be found out differences in the high spring type barleys, but in the low, it was grately shortened by postponing the sowing time. The barley height of rosette form had no difference at any sowing time.difference at any sowing time.

  • The major kernels$(7{\sim}10\;mesh)$ of naked barley were pearled to give an average yield for each pearling of about 5% flour, with 70% of the naked barley left as residual kernel. The contents of protein, fat and ash were in the highest in the fraction of 1,2 and 3, respectively. These fractions contained 1, 4 times of protein, 3.16 times of fat and 3.08 times of ash more than those values of original kernel. Residual kernels contained 62% of protein, 38% of fat and 35% of ash in the original kernel. Among minerals, the content of Ca, Na, Fe and Mn were in the highest in fraction 1 ; P, Mg and Zn in fraction 2 ; and K and Cu in fraction 3. Concentrations of these minerals were the lowest in the residual kernel. Magnesium showed the deepest concentration gradient, while iron was evenly distributed within the kernel.

  • The objective of the study was to investigate skin temperature responses of Hanbok when it was worn. Two healthy females(average 21 years, 155cm and 60kg were exposed to a climatic chamber(Room Temp. $21{\pm}1^{\circ}C,\;52{\pm}2%R.H.$, 0.15m/s). During the experiment, rectal temperature, skin temperature of 9 areas, clothing microclimate, subjective sensation were measured. Chima and Jogory to be made of silk nobang(SN) or Ramie were worn for summer. Polyester(P) Chima and Jogori(R) could be wort for spring and autumn. For winter, silk Chima, Jogori(S) and Durumagi(D) were commonly worn. Rectal temperature was high in order of naked(N), R, SN, P, S, D. However Mean skin temperature was reversely high in order of D, S, SN, R, P, naked. In naked, skin temperature was high in order of head, trunk upper extremity and lower extremity. But on wearing of Hanbok, it was the highest at the chest except head regardless of kinds of clothing ensembles. Skin temperature of upper arm was secondly highest on wearing the silk ensemble and the Durumagi ensemble, but skin temperature of buttock was secondly highest on wearing the silk nobang ensemble and the ramie ensemble. Skin temperature on wearing the silk ensemble was generally higher than those on other clothing ensembles. Local and mean skin temperatures on wearing the silk ensemble and the Durumagj ensemble were generally higher than on other clothing ensembles. Heat resistance of the fabric might have affected on the local skin temperature.

  • This paper is to provide an analysis of the aspectual nature of naked infinitives(NIs) of English perceptual reports. Higginbotham(1983) proposes that only ‘active’ or ‘transient’ verbs can be used as NIs of English perceptual reports, but ‘state’ verbs cannot. This is called “confinement to the active or transient”. But there will be one problem when NIs of English perceptual reports are negatives. This is why the meaning of negative NIs of English perceptual reports may be static, which isn't in line with “confinement to the active or transient”. There are similar problems with ‘state’ NIs of English perceptual reports. In this paper some of these problems can be solved with the “Event Structure” of Pustejovsky(1991). According to Pustejovsky(1991), ‘process’ and ‘transition’ verbs have sub-eventual individuation units, but state verbs have no such units. It is the units that make it possible for ‘process’ and ‘transition’ to be perceived. As a result ‘process’ and ‘transition’ verbs are suitable for NIs of English perceptual reports. Nevertheless, there are still some problems unsolved. Moreover some state verbs are grammatically used as NIs of English perceptual reports. This paper proposes that these state verbs have “potentiality of transition”, and the potentiality comes from only the combination of the two parts of the complement - the subject and the naked infinitive. And the potentiality causes the “Event Structure” of Pustejovsky(1991) to be modified. And this modification makes it possible for us to explain aspect of NIs of English Perceptual Reports. It is concluded with some implication for Korean learners of English as a Foreign Language.

  • To understand the effects of adding different gums (guar, xanthan, and locust bean gums) on naked barley flour (NBF), the rheological and pasting properties of NBF-gum mixtures were measured at different gum concentrations (0, 0.3, and 0.6% w/w). Steady shear rheological properties were determined by rheological parameters for power law and Casson models. All samples showed a clear trend of shear-thinning behavior (n=0.16~0.48) and had a non-Newtonian nature with yield stress. Consistency index, apparent viscosity, and yield stress values increased with an increase in gum concentration. Storage modulus values were more predominant than loss modulus values with all concentrations of gums. There is a more pronounced synergistic effect of elastic properties of NBF in the presence of xanthan gum. Rapid visco analyser pasting properties showed that the addition of gums resulted in a significant increase in the peak, breakdown, setback, and final viscosities, whereas the pasting temperature decreased.
