  • Cowpea(Vigna unguiculata L. Walp) has excellent physical properties and texture of starch, so it is mainly used in various ways for songpyeon sediment, rice-cake paste, and porridge. To utilize it as various processed products such as songpyeon sediment and cowpea milk, 'Okhyun', which has green cotyledons and black seed coats and can be harvested by combine was developed. A cowpea variety 'Okhyun' was improved from the cross between IT145379 and IT208081 at the JARES in 2022. 'Okhyun' has an erect plant with an intermediate plant habit, a light purple-colored corolla, and heart-shaped leaflets. 'Okhyun' has green cotyledons and black seed coats, and has straight black brown pods when mature. The stem length of 'Okhyun' is 47cm, and the weight of 100-seed weight was 12.9g, which was lower than the control variety 'Okdang'(16.6g). 'Okhyun' contains 25.8mg/100g of anthocyanin, 279mg/100g of total polyphenols, and 335mg/100g of total flavonoids, respectively. The average yield of 'Okhyun' was 1.97ton per hectare, 11% higher than that of the control cultivar 'Okdang'. 'Okhyun'' does not require the installation of an espalier-net net, so it is possible to harvest with a combine. In addition, 'Okhyun' variety with green cotyledons and a black seed coat is expected to contribute to developing regional specialties and various processed products.

  • Background: As the habitat changes in Korea due to climate change, the emergence of disease-mediated vectors is increasing rapidly. Thus for the surveillance of mosquito- and chigger mite-borne disease, their seasonal prevalence and species composition were investigated at seven locations in Daegu, Gunwi and Sangju. Methods: Mosquitoes were collected twice every month from five collection sites using a black light and BG sentinel traps in Daegu and Gunwi from April through November. Chigger mites were investigated twice per month from wild rodents caught with Sherman live traps in Gunwi and Sangju from April through May and September through November. Results: A total of 2,361 female mosquitoes were collected. Cowshed (626 individuals, Trap index (TI) 44.7) and Kyungpook National University campus (846 individuals, TI 60.4) in Daegu had the highest number of mosquitoes in the black light and BG sentinel trap, respectively. The mosquitoes were collected more by BG sentinel trap than the black light trap. Nine mosquito species were trapped, and the Culex pipiens complex was the most commonly mosquito (1,397 individuals, 59.2%), followed by Anopheles sinensis (554 individuals, 23.5%). Anopheles sinensis (531 individuals, 51.9%) and Culex pipiens complex (1,142 individuals, 85.4%) were the most mosquitoes from black light and BG sentinel trap, respectively. In terms of seasonal prevalence, the highest abundance was in July, with 824 individuals collected. In chigger mites, eighty-one wild rodents of five species that are hosts of chigger mites were collected; among them, 53 and 25 individuals of Apodemus agrarius and Crocidura suaveolens, respectively were trapped. Leptotrombidium pallidum was a dominant species, with 2,467 individuals collected (67.8%). Conclusions: The mosquito was the dominant species in Culex pipiens complex and the highest in July and August. Apodemus agrarius was most abundant in wild rats and Leptotrombidium pallidum was dominant in the collected chigger mites.

  • This study examined the seasonal, regional distribution of mosquito vectors related with disease vectors in the Jeju. From March to November, sample were collected from 11 points in four environmentally different sites in Jeju Island. Samples were collected twice a month using a black-light trap and a BG sentinel trap. Overall, five genera and seven species types of 6,042 female mosquitos were collected. Among the collected mosquitos, 4,159 (68.8%) and 1,348 (24.4%) were Culex pipiens and Aedes albopictus, respectively, making them the dominant species. Additionally, collection using the black light trap produced 72.8 entities per trap in Jungang-dong service center in the center of the city, which was the highest value, while the lowest amount of 1.4 per trap was recovered from the airport. When the BG sentinel trap was used, the largest recovery was observed in the port, where there were 71.7 entities per trap, while the lowest amount of 28.3 entities per trap was recovered at Gealmae Eco Park. The overall number of mosquitoes collected started to increase from May, and reached the largest value of 1,156 (19.1%) in August. Trapped mosquitoes are created 364 pools of up to 50 grains per pool, by season, by environmental, and by species. When the pools were used, no flaviviral infection was observed upon real time RT-PCR.

  • Frequently faced with dangerous situations, for evidentiary purpose in case of civil and criminal liability challenges, car drivers in Korea have been armed with so-called 'black boxes'; however, which are just video recorders in vehicles rather than real 'black boxes' that are equipped in the airplanes. In the United States, they are called EDRs(Event Data Recorders), more technically, which means that they record data of events happened while driving, such as velocity changes, airbags deployment, seatbelt wearing etc. just like in the airplanes. EDR technology is quickly becoming more advanced, more widely available, and less expensive; however, new concerns are emerging : the privacy of drivers. In U. S., vehicle manufacturers and insurance companies and the governmental agencies including the courts and legislatures are the main parties in terms of the EDR concerns. In order to determine the best way to regulate EDR, it is necessary to balance all the merits, such as safety, privacy, truth, justice and efficiency, to support a legal framework regulating the EDR concerns. This article, in light of the regulation of EDR and experience therof in the United States, examines EDR technology itself, particularly with respect to the automobile industry, describing its history, its current state, and trends that may change it in the future; and explains how the National Highway Transportation Safety Agency (NHTSA), legislatures, courts have approached EDR data. At the early stage of regulation on EDRs in Korea, examining U. S. legal framework and usages would help for successful establishment of legislation and regulation.

  • The main purpose of this essay is to suggest that Faulkner's "pro"-lynching letter published in Commercial-Appeal in 1931 does not contradict his antilynching works such as "Dry September," Light in August, Go Down, Moses, and Intruder in the Dust. In the letter, Faulkner writes, "they [lynching mobs] have a way of being right." The remark has been interpreted as the expression of Faulkner's sympathetic attitude toward lynching mobs; however, it can be also seen as Faulkner's observation and criticism of the southern white people's structures of feeling in his time that stubbornly justified lynching as a way to do justice to black people who did "not" deserve to be a legal subject. This essay argues that Faulkner understood that the legislation of anti-lynching law alone could not save black people from the violence of lynching as far as white people believed that black people were not their equals and that lynching was a right means to fulfill social justice. Faulkner's fictions such as Light in August and Go Down, Moses provide moments in which white male characters feel as if they were social others, and their experiences work as an ethical urge for them to stand up for social others. This essay illuminates how Faulkner depicts the process of white male characters' identity formation as a violent break from his strong tie with black friends, how they reverse the process to blur the border again through the experiences of becoming-other, and how the experience of becoming-other has a potentiality to play the role of an ethical agency in stopping the custom of lynching in the South.

  • Standard carnations are widely used in flower design as a mass flower, but there is a limit to the use in that it can not be used in various colors in addition to its own color. The purpose of this study was to investigate how does artificial dyes affect vase life, using standard carnations, and to improve utilization of dyeing carnations in floral design. Using standard carnation 'White Liberty', dyeing experiment was performed according to four kinds of chemicals for each of six dyes. Six different dyes from Koch(Robert Koch industries Inc., USA) as follows light blue(2386), lime green(2315), christmas red(2506), lavender(2200), orange fire(2268) and black(2012) have been used and four different chemicals as follows distilled water, 4% ethanol, 3% sucrose and 100mg·L-1 citric acid have been used with the cut Dianthus caryophyllus 'White Liberty'. As a result, six different dyes showed fast and excellent dyeing with 3% sucrose and 100mg·L-1 citric acid treatment. But vase life in other dyes except black and lavender tended to be similar to control(7 days).

  • Black has been the most important color of all since the ancient times when the recognition of black roused, as well as during most of the eras; and can especially be said as the main color which controlled the chronicles of fashion. The purpose of the study was to broaden the application of black color image make-up by inquiring into make-up design elemental characteristics of lines and textures, after classifying magazine illustrations and advertisement make-up images using black. The photos which made effective use of black among fashion illustrations, magazine advertisements after 2001 were classified in to each type, and make-up expression method and characteristics according to design element of each image type was analyzed. The conclusion of such study was the following. 'Erotic image' showed contrast effect between eye make-up and lip color by using pale tone or red color. 'Mannish image' emphasized form and texture of eyebrow by restraining the colors of eyelids with natural brown tone eye make-up; 'Modern image' expressed vague eyebrow to bring the sensation of the direction of eye shadow on eyelids and eye line as well as slant line to relief. 'Kitsch image' showed free and light imagery by creating unique hair style with various colors; expressing lips mostly with colors similar to skin tone or by restraining colors on lips. 'Decadence image' showed messy and foul sensation with unstandardized eye make-up and matt skin of shimmer, glossy and pale tone, also with black colored lips; 'Retro image' expressed reinterpretation of images from 1920${\sim}$1960 to contemporary styles.

  • The improvement of superior black soybeans could be accomplished through maintenance and use of black soybean collections. This experiment was carried out to select pure-line from the domestic black soybean genotypes, and survey some agronomic characteristics of the collections. Nine hundred and sixty five lines of black soybeans were collected in 197 locations on spring, 1991. Higher distribution was present in broad leaves, purple flower color and tawny pubescence color which were approximate to be 97, 90 and 98%, respectively. In pod color of black soybean collections, 60% was brown and 27% was light brown and 10% was dark brown. The 61 to 70 days were required for flowering in 61 % of the collections. Growing days of 51 % of black soybean collections ranged 121 to 130, and those of 37 % were over 131 days.
