The growth performance in the first year of life of 892 Black Bengal kids was studied in four different locations in Bangladesh, e. g. (1) Bhabakhali, (2) Trisal, (3) Aishara and (4) Akhrail. Birth weight of kids of region 1, 2 and 3 were almost similar (1.01 kg) with significantly lower birth weight in region 4 (0.88 kg). Effect of birth type and sex were significant with higher weights for single (1.03 kg) v. twin (0.98 kg) v. triplet (0.92 kg) and male kids (1.03 kg) v. female (0.93 kg). Monthly weights of kids followed the same pattern as birth weight. Monthly weights of kids in region 1, 2 and 3 were similar with significantly lower weight for region. 4 Birth type and sex affected monthly weights in different regions where single and male kids had significantly higher weights for all the regions. The analysis of variance reveals that regional significant differences for average daily gains were noticed for the periods from birth to 3 and 9 to 12 months of age. The highest gains were noticed for region 2 ($51.9{\pm}2.4kg$) and the lowest for region 1 ($38.2{\pm}2.3kg$) with similar values for region 4. From the results it is revealed that growth performance of Black Bengal kids varied in different regions, which might be caused by inappropriate management and inadequate feed availability around the year and stressful environmental conditions.

Background: In the absence of clear guidelines for facial aesthetic surgery, most surgeons rely on expert intuitive judgement when planning aesthetic and reconstructive surgery. One of the most famous theories regarding "ideal" facial proportions is that of the golden proportion. However, there are conflicting opinions as to whether it can be used to assess facial attractiveness. The aim of this investigation was to assess facial ratios of professional black models and to compare the ratios with the golden proportion. Methods: Forty photographs of male and female professional black models were collected. Observers were asked to assign a score from 1 to 10 (1 = not very attractive, 10 = very attractive). A total of 287 responses were analysed for grading behaviour according to various demographic factors by two groups of observers. The best graded photographs were compared with the least well-graded photographs to identify any differences in their facial ratios. The models' facial ratios were calculated and compared with the golden proportion. Results: Differences in grading behaviour were observed amongst the two assessment groups. Only one out of the 12 facial ratios was not significantly different from the golden proportion. Conclusions: Only one facial ratio was observed to be similar to the golden proportion in professional model facial photographs. No correlation was found between facial ratios in professional black models with the golden proportion. It is proposed that an individualistic treatment for each ratio is a rather better method to guide future practice.

Background: The leaf temperature ($T_{LEAF}$) is one of the most important physical parameters governing water and carbon flux, including evapotranspiration, photosynthesis and respiration. Cnidium officinale is one of the important folk medicines for counteracting a variety of diseases, and is particularly used as a traditional medicinal crop in the treatment of female genital inflammatory diseases. In this study, we developed a model to estimate $T_{Leaf}$ of Cnidium officinale Makino based on black globe temperature ($T_{BGT}$). Methods and Results: This study was performed from April to July 2018 in field characterized by a valley and alluvial fan topography. Databases of $T_{LEAF}$ were curated by infrared thermometry, along with meteorological instruments, including a thermometer, a pyranometer, and an anemometer. Linear regression analysis and Student's t-test were performed to evaluate the performance of the model and significance of the parameters. The correlation coefficient between observed $T_{LEAF}$ and calculated $T_{BGT}$ obtained using an equation, developed to predict $T_{LEAF}$ based on $T_{BGT}$ was very high ($r^2=0.9500$, p < 0.0001). There was a positive relationship between $T_{BGT}$ and solar radiation ($r^2=0.8556$, p < 0.0001), but a negative relationship between $T_{BGT}$ and wind speed ($r^2=0.9707$, p < 0.0001). These results imply that heat exchange in leaves seems to be mainly controlled by solar radiation and wind speed. The correlation coefficient between actual and estimated $T_{BGT}$ was 0.9710 (p < 0.0001). Conclusions: The developed model can be used to accurately estimate the $T_{Leaf}$ of Cnidium officinale Makino and has the potential to become a practical alternative to assessing cold and heat stress.

Even though Paule Marshall and Ishmael Reed have differences of gender, generation, and literary techniques, they share common points in dealing with cultural conflicts and racial discrimination in the United States as Afro-American Writers. As black minority writers, Marshall and Reed write out of a perspective of forced immigrant/fragmentary native consciousness. The purpose of this paper is to investigate the protagonist's reaction to racial prejudice, different cultures and their attempts to reconcile and to coexist with other races and their culture in these writers' representative works. Marshall's uniqueness as a contemporary black female artist stems from her ability to write from the three levels, that is, African American and Caribbean black. So, Marshall's Brown Girl, Brownstones represents an attempt to identify, analyze, and resolve the conflict between cultural loss/displacement and cultural domination/hegemony. Reed's Japanes by Spring offers a blistering attack upon the various cultural and racial factions of the academy and the bankrupt value systems in America. Reed's depiction of Jack London College's existing racial problems-later compounded by the cultural dilemmas that accompany the Japanese occupation of the institution-reveals his interest in highlighting the ways in which any monoculturalist ideology ultimately results in racist and culturally exclusive policies. Marshall's and Reed's novels provide opportunities for reader to explore various manifestations of intercultual and interethnic dynamics. They present the possibility of reconciliation and coexistence between different race and ethnic cultures through asserting a cultural hybridity and multiculturalism.

This article briefly researched the Picture of Welcoming the Governor of Pyongan Province painted by Kim Hong-do, penname Danwon(1745-1818?). The Picture was composed of three parts and its historical and pictorial back-ground were reviewed firstly. And later the dress and its ornament appearing on the Picture were studied. In the historical viewpoint of dress and its ornament, the Picture shown all sorts of dress from lower class maids and servants to higher officials-dignatories and governor, and dealt with nearly all dresses. In order to support and to make better understand the dresses of that age, some Korean literary works of the same period depicting the dress and its ornament were also selected. This article dealt with the dress and its ornament. especially that of 18th century of the Yi Dynasty, and comparatively studied for our folk painting with literary works. Also the picture enabled to make this study was an important data of our old dress and its ornament. This painting was considered as one of our cultural treasures. Several conclusions drawn out from this study as followings: 1) In male and female dress of lower class people; male dress was consist of trouser and coat, and coat, and over the coat SOCHANGYI were used. Female dress was basically consist of skirt and these were white color of their favourite. Mainly simple color was used for clothing and its dress style were CHAKSOO-HYONG (narrow sleeve style) which convenient for a work. 2) Yangban's dress was consist of trouser, coat and over the coat, usually DOPO(over-coat) were used and some case JICKRYONGPO (a sort of over-coat) or CHANGYI were also used. These were GWANGSOO-HYONG (wide sleeve style) of inconvenient for a work. 3) In head-gear, there was no difference of the higher and the lower. They usually used HEUC-KRIP (black Korean hat). The OCKJUNGJA, GONJAKMI (peacock tail), HOSOO (tiger beard), and YOUNGJA (chin strip) were used according to officials ranks as head-gear's oraments. 4) Local petty officials used ordinary dress and CHUPRI (warn-dress) were also used by them, and military officials used war-dress of tight sleeve. 5) The belting of over-coat are different in color according to official grade. The higher grade wore red-wide belt, but generally black narrow belt for ordinary officials. 6) All KISAING girl wore SAMHYEOIJANG upper coat. And their head ornament were black KARIMA for grown KISAING. SAYANG hair for DONGKI or maiden KISAING and BINYEO (an ornamental rod of women's hair) were inserted into the hair of rear down part of head. The water carring maid wore BANHYEOIJANG upper coat and no KARIMA were on head and their coat were gloomy color. Above mentioned are several conclusions, and there migh be a false or erroneous explanations of 18th century dress and its ornament, however I considered they were data for blank period of quite unknown.

In a majority of mammals, male infants have heavier body mass and grow faster than female infants. Accordingly, male offspring nursing requires a much greater maternal energy contribution to lactation. It is possible that the maternal-fetal immunoendocrine dialog plays an important role in female preparation for lactation during pregnancy. Immune system genes are an integral part of gene regulatory networks in lactation and tumor necrosis factor alpha ($TNF{\alpha}$) is a proinflammatory cytokine that also plays an important role in normal mammary gland development. The aim of this study was to evaluate the influence of the sex of calf and/or the -824A/G polymorphism in the promoter region of $TNF{\alpha}$ gene on milk performance traits in Black Pied cattle over the course of lactation. We also studied the allele frequency differences of -824A/G variants across several cattle breeds, which were bred in different climatic conditions. The G allele frequency decreased gradually over the course of lactation events in the Black Pied dairy cattle because of a higher culling rate of cows with the G/G genotype (p<0.001). In contrast to the genotypes A/A and A/G, cows with G/G genotype showed significant variability of milk and milk fat yield subject to sex of delivered calf. Milk yield and milk fat yield were significantly higher in the case of birth of a bull calf than with a heifer calf (p<0.03). The G allele frequency varies from 48% to 58% in Grey Ukrainian and Black Pied cattle to 77% in aboriginal Yakut cattle. Our results suggest that the $TNF{\alpha}$-824A/G gene polymorphism may have an influence on the reproductive efforts of cows over the course of lactation events depending on the sex of progeny. Allocation of resources according to sex of the calf allows optimizing the energy cost of lactation. This may be a probable reason for high G allele frequency in Yakut cattle breeding in extreme environmental conditions. Similarly, the dramatic fall in milk production after birth of a heifer calf increases the probability of culling for the cows with the G/G genotype in animal husbandry.

The purpose of the present study were 1) to identify the dimensional structure of impression formed of a female figure, 2) to analyze effects of several elements of apparel design on impression formation of the figure in suit. The experimental materials developed for this study were a set of stimuli and a response scale. The stimuli consisted of 60 drawings made by identical manipulations of 3 indepndent variables in 3 clothing styles(suit, dress and pants with blouse). The independent variables were (1) five clothing colors (red, blue, yellow, white and black), (2) two lengths(short/long) of suit skirt, dress, and pants (3) two types of blouse and dress collars (shirt collar/ribbon collar). The 7-point semantic differential response scale to measure the dependent variables (formed impressions of the female figure) was composed of 37 bipolar adjectives. Further- more, two open-ended questions were used for interpretation of the reponses. The study proceeded in three independent experimental part was based on the 3 clothing styles using a 5(color)$\times$2(length)$\times$2(collar) factorial design. Subject were 200 female undergraduate students reandomly assigned to one of 20 combinations in each part of the experiment. The data were analyzed by factor analysis, 3-way ANOVA and Multiple Classification Analysis. Five factors emerged to account for the dimensional structure of impression of the female figure in specific attire. These factors included three basic dimensions of impression identified as potency, activity and evaluation, confirming the results of previous studies. Result from open-ended questionaire supported the theoretical perspective of Schneider, Hastorf and Ellsworth on the procedure of impression formation.
