  • We investigated the emergence patterns of Chilo suppressalis (Lepidoptera: Crambidae) adults using sex pheromone traps in the three northeastern areas, Dandong (40°07'N 124°23'E) (Liaoning province), and Gongzhuling (43°30'N 124°49') and Longjing (42°46'N 129°26'E) (Jilin province), China, in 2020 and 2021. Two times of adult flight seasons were isolated clearly during the rice growing periods in the all areas, in which the first season from mid May to late July, and the second season from mid July to mid September were observed. The adult emergence seasons in the areas at higher latitude were later than that at lower latitude. Using the adult emergence data during the first flight seasons, the second flight seasons were estimated through insect phenology modelling, and compared with the observed data. Temperature-dependent life history models (developmental rate, development completion, survival rate, adult aging rate, total fecundity, oviposition completion, and adult survival completion) were collected or constructed for each life stage of C. suppressalis, in which the data from the four previous studies were used. Those models were combined in an insect phenology estimation software, PopModel, and operated for the observed areas. In the results, the phenology modelling operated with the models based on the data of shorter larval periods in the previous studies estimated more accurately the second flight seasons. In 2021, we investigated the change of damaged hill ratios of rice with observing the adult emergence at Dandong and Longjing, 2021. The increase periods of damaged hill ratios of rice were observed two times during the total rice cultivation season, which may be caused by different generations of C. suppressalis larvae.

  • Chrysanthemum plants are one of the most economically important plants in South Korea. Both virus and viroid can cause diseases and economic damage to the plants. In this study, we investigated the detection of seven viruses and two viroids in 350 chrysanthemum plants cultivated in Yesan-gun, Chungcheongnam-do. Two viruses, chrysanthemum virus B (CVB) and tomato aspermy virus (TAV), and two viroids, chrysanthemum chlorotic mottle viroid (CChMVd) and chrysanthemum stunt viroid (CSVd), were detected in this study. The two viruses were detected in six samples and one sample, respectively. The two viroids were detected in 97 samples and 21 samples, respectively. The nucleotide sequences of the CVB-CN-Y, TAV-CN-Y, CChMVd-CN-Y, and CSVd-CN-Y obtained in this study showed 83.7-86.9%, 99.2-100.0%, 94.4-99.5%, and 95.7-99.7% identity, respectively, compared to their other strains/isolates. The CVB-CN-Y and TAV-CN-Y showed the greatest nucleotide sequence homology to CVB-GS1 and three TAV isolates (TAV-V, TAV-P, and TAV-ChJ), respectively. The CChMVd-CN-Y and CSVd-CN-Y showed the greatest nucleotide sequence homology to CChMVd-Horst and four CSVd isolates (Au1.1, K4pop, Sagae, and Tochigi), respectively. This study is the report on the infection rate of viruses and viroids in chrysanthemum plants cultivated in Yesan-gun in 2021.

  • "Jungmo2510", a rye cultivar, Secale cereal L., was developed by National Institute of Crop Science, RDA in 2015. It was developed from open pollination from within 10 rye cultivars or lines including "Chochun" in 1995. The line "SR95POP-S1-523-1-5-5-4-7-3-B-16-3-19" was selected for its excellent agronomic appearance and was placed in yield trials for two years from 2011 to 2012. The line was designated "Homil55" and was placed in regional yield trials at the four locations around Korea from 2013 to 2015, during which time the name "Jungmo2510" was given. This cultivar is an erect plant type and leaves of short and broad size with a green color, a yellow colored, medium-diameter culm, and a yellowish brown-colored, medium-size grain. The heading date of "Jungmo2510" was April 16, which were 2 days earlier than that of "Gogu". "Jungmo2510" also showed similar to winter hardiness and greater resistance to lodging compared to those of the check cultivar. Over three years, the average dry matter yield of "Jungmo2510" was 802 kg 10a-1 , which was harvested in late April and was lower than that of the check cultivar "Gogu" (825 kg). The seed productivity of "Jungmo2510" was approximately 481 kg 10a-1 , which was 2.4% less than that of the check. "Jungmo2510" was higher to than "Gogu" in term of protein content (9.1% and 8.0%, respectively), total digestible nutrients(TDN)(57.5% and 55.5%, respectively), and TDN yield 10a-1(419 kg and 392 kg, respectively). This cultivar is recommended as a fall sowing crop in areas where the average daily minimum-mean temperatures are higher than -12 ℃ in January, and as a winter crop for whole-crop forage before the planting of rice or green manure around Korea.

  • The purpose of this study is to examine the effect of Korean dramas selection factors for Chinese audiences on the national image of South Korea. The results of this study were as follows: First, selection factors of Korean dramas for Chinese audiences were categorized 'subject and content', 'direction and background music', and 'style of actor or actress'. Among these factors, this study was found that a factor of drama's 'subject and content' had an effect on the selection of Korean dramas for Chinese audiences. Second, 'touristic factor', 'cultural factor', and 'stylistic factor' were examined as a national image factor of South Korea for Chinese audiences. The Chinese audiences surveyed responded positively on 'cultural factor'. The images delivered through the Korean TV dramas have very much influenced the Chinese audiences to view contemporary Korean society as a country of modern and urban elegance. Furthermore, the audiences cognized South Korea is a friendly nation as South Korea and China has a similar cultural background like the Confucian culture. Third, the study found selection factors of Korean dramas for Chinese audiences had positive effects on the national image of South Korean. These positive influences were found on 'touristic factor', 'cultural factor', and 'stylistic factor' From these results, Chinese audiences watch Korean dramas focused on 'subject and content', 'direction and background music', and 'style of actor or actress'. Watching Korean dramas help to create the friendly national image of South Korea. The study shows a possibility to increase an interest and preference on the Korean pop culture.

  • The purpose of this study is to evaluate the imbalance of green space using various spatial analysis methods and to establish the management zone for green space with service supply in the aspect of its use in Daegu. The total green space of Daegu is 48,936.1ha which is the second among 7 metropolitan cities of Korea. According to the imbalance analysis of green space, the Gini's coefficient based on the area was not high, on the other hand, the Gini's coefficient based on the population was high by above 0.6. According to an evaluation of service supply of green space in Dalseo-gu, the area within about 100m around large green space was supplied with green spaces of above $25m^2$/pop. On the other hand, the area such as Sangin, Jukjeon, and Yongsan was not almost supplied with green space. Finally, 'Rich zone', 'Fair zone', 'Poor zone', and Broken zone' could be established based on the service supply for the management direction of green space. The findings from this study can be used as the basic data for selecting the construction priority of new green spaces.

  • Our Korean cuisine, due to growing interests in Korean culture along with outstanding performance of K-pop stars, is attracting worldly attention. As the worldly food pursuit tendency is changing from"fast food" to "slow food", preference for our Korean cuisine, which is well-known for its healthiness, is growing. However, our Korean cuisine, in terms of the world citizen's preference, as receiving evaluation for being lacking behind of Sushi of Japan, Dimsum of China, pizza and pasta of Italy, rice noodle of Vietnam, even to Indonesian and Middle-East foods, has not been achieving drastic advancements despite the cosmopolitan's attention. The previous studies were suggesting that, failure of a localization strategy that changes our traditional taste and aroma adaptive to foreigners' preference, is a cause for this. This study, through case studies of Korean food businesses in the US which have achieved a success through localization strategy, attempts to propose the following global entrepreneurial strategy of Koran food at the US dining out market. As a global entrepreneurial strategy for success, we propose, first a sales strategy not for Koreans but for local people as main customers, second a customization strategy which is not our traditional way but that meets local standard, and finally a committed entrepreneurship.

  • The purpose of this study was to approach to the internal meanings included in the Happening and the culture of hippies, by analysing the basic mental conditions in the process of the Happening. And this study was composed of the concept and the development of Happening, the characteristics of the hippies that related in the midst of the happening's background, and the formativeness between these factors and hippies'fashion. Since the happening a genre of fine arts expression attended the New School for social research in New York in 1954, Allan Kaprow direct-influenced by John Cage used the word 'Hapening'first, practicing '18 Happenings in 6 parts'at the Rueben gallery in 1959. Kaprow's 18 Happenings was one of the earliest opportunities for a wider public to attend the live events that several artists had performed more privately for various friends. Despite the very different sensibilities and structures of artist's works, artists were all thrown together by the press under the general heading of 'Happening', following Kaprow's 18 Happenings. Being considered as the root of the Happening 'Expression of Sound'of John Cage was the discovery of the exisiting thing- the Happening. Most artists were to be deeply influenced by Cage's theories and attitudes-that is, his sympathy for Zen Buddihism and oriental philosophy-and by reports of the Black Mountain events. These events would directly reflect contemporary painting and stemmed from the Futurists, Dadaists and Surrealists. And Happening's development background was based on the culture of hippies. Swinging London had been under the sway of psychedelic drugs and utopian visions of 'hippie'wave sweeping in from Califonia. This wave, which affected solid middle-class youth first and formost, began in Haight Ashbury in San Francisco. Without dwelling on the hippie movement here, it is worth nothing that it resulted from the convergence of several undercurrents : consciousness-expending drugs, the anti-Vietnam war developments, the impact of English pop groups on American music and the rise of protest songs, and finally the beatnik tradition of non-conformism. Hippie culture and its pursuit of love, peace and psychedelia was the antitheses of 1960s main street fashion. The media gave everyone with long hair the label of 'hippie', but it was always a very loose collage of attitudes and styles. The rejection of sexual taboos was conveyed by the hippie's refusal to wear. Although the bold exposure of body raised controversies because it went against the existing moral values, it has a significant implications. Psychedelics brought mind-expansion and the possibillity that modern technology (light show, synthesized electronic sounds), new fabrics or colors, and LSD could be utilized to provide an escape route from the dreariness of modern life. During the 1960s, traditional costumes, many of which had never been seen outside their native regions, became sought after and adopted in the West, initially by the young, who wanted to demonstrate their solidarity with cultures uncontaminated by mass industry. The most ardent proponents of such folk costumes were the hippies. Hippies dress was sometimes decribed as 'anti-fashion', produced by a patchwork of ragged cast-offs and flamboyant accessories, of outmoded Western dress and time-honored ethnic garments all combined, modified and permutated into variety of personal statements. 'Flower Power'became a reality. From the results of this study, we can see the expanding trend of the influence and the concept of the sew art genre 'Happening'in the formativeness as well as the fine arts field.

  • In order to analyze environmental impact of livestock manure and organic fertilizers, this study investigated livestock-breeding and pollution loads, the status of individual and public livestock manure treatment facilities, and the status of production, supply and components of compost and liquid fertilizers in the Nonsan area. Also, on a trial basis, this study investigated the life cycle of the environmental impact of livestock manure and its organic fertilizers on stream, groundwater, and agricultural soil. The results are as follows. Firstly, were detected the range of $0.13{\sim}1.32{\mu}g/L$ of As, $0.004{\sim}0.467{\mu}g/L$ of Cd and $0.5{\sim}9.2{\mu}g/L$ of Pb as a harmful substances which show lower concentrations than person preservation criteria of water qualities and aquatic ecosystem. However, it is not clear that heavy metals affect environment such as stream, groundwater and agricultural soil. Secondly, this influence could change according to investigation time and treatment efficiency. As were detected large amounts of persistent organic pollutants(e.g. $14.24{\sim}38.47{\mu}g/L$ of acetylsalicylic acid, $1.17{\sim}2.96{\mu}g/L$ of sulfamethazine, and $2.25{\sim}174.09{\mu}g/L$ of sulfathiazole) in effluent from livestock farms and small amounts of sulfathiazole($ND{\sim}1.63{\mu}g/L$) in the stream, it is necessary to monitor POPs at individual and public livestock manure treatment facilities. However, significant environmental impact did not appear at groundwater and agricultural soil in the test area supplied with liquid fertilizers. These results could be applied to investigate the environmental impact of livestock manure through a comprehensive livestock manure management information system.

  • This study examines the meaning of retro phenomenon and its background of establishment that showed in the pop culture. And it finds out the retro phenomena in the domestic fashion trends. And it defines the characteristics of dress and its ornament in the retro phenomena that have shown in the Korean movies since 1998. By doing this, it examines the relationship between movie dress and street fashion while it compares the styles in the 50s 70s with the retro fashion that is currently emerging. The results of the study are as follows. First, the hippie look in the 60s represented a distinctive characteristic of how they rejected traditional lifestyles. Hippie's romantic femininity that showed in the movie of 'Oollala Sisters' received a spotlight as a necessary style in the modern fashion trend. Second, while the funk look in the 70s was a style of disorder and disgust, the movie gives it a possibility of fashion with a converted sense as a vanguard fashion while embracing the funk look. Third, the layered look in the 70s was expressed with layered items, while the current layered look emphasizes layered textiles as shown in the movie of 'Hae-Jeok Became The Disco King'. Fourth, the feminine look which was a symbol of restraint shows a mixed style with delicate feminine items as shown in the movies, 'The Harmonium In My Memory' and 'Ditto'. Fifth, the training look that has two stripes as shown in the movie 'the Friends' is considered as casual wear, which is functional and easy to move at the end of the 20th century. Finally, the romantic images of school look, as shown in the movies 'the Friends' and 'Hae-Jeok Became The Disco King', show a renewed mixed & unique style. This study has its significance in the sense that it verifies the fact that the movie dress does not show the characteristics of the works that momentarily passes the screen, but it becomes a foundation of the future fashion design. At this time that Korean movies are highly developing, a through study on the movie fashion will not only give a direction of future in the modern fashion, but it will also give a developing momentum in the Korean movie dress.

  • Palmitoyl-oleoyl-oleoyl (POO) and palmitoyl-oleoyl-palmitoyl triacylglycerol rich fraction (PSL) was obtained from the acetone fractionation of palm stearin. The fatty acid composition (total and positional), tri-acylglycerol species, and solid fat index (SFI) were compared among the blends of natural vegetable fats (sal fat, illipe fat, kokum fat, shea stearin fat, and shea butter) and PSL with different ratios (50:50, 60:40, 65:35, 70:30). In total fatty acid composition of PSL, palmitic, oleic, and linoleic acids were the major fatty acids, whereas in natural vegetable fats stearic and palmitic acids were the major fatty acids. Moreover, oleic acid was a major fatty acid at sn-2 position in sal fat, illipe fat, and kokum fat. The TAG species was analyzed by reversed-phase HPLC, from which the PN value ranged from 46 to 54. When natural vegetable fats and PSL were blended with different ratios, decreasing the amount of PSL resulted in increasing SFI in most cases. Among blends, the SFI of sal fat and PSL were most similar to commercial cocoa butter equivalent (CBE).
