'Reboot' and 'Homage' are using as creative techniques in traditional storytelling media fields such as movies or dramas, but the possibility of expanding the transmedia story world has not yet been presented. This study was written to present a new concept of transmedia story world expansion type using the 'Reboot' and 'Homage' methods. 'Reboot' and 'Homage' are typical storytelling methods of K-POP idol groups that need to develop content. I selected , , and , which have built their story world, and examined both the narrative creation section and the marketing application section. The result of the study is as follows. First, EXO is an example of a reboot case. They set the original set as 'past' and insert the new storylines. Second, BTS is an example of a character's reboot. They built a story world by paralleling 'Idol BTS' and 'Character BTS'. Third, Wanna One is an example of the original story world's homage. They reorganize the story world of and attracting the attention of the existing audience. Fourth, BTS is an example of other media homage which reinterprets the meaning of BTS characters and story world by using the meaning of classic works.

Pseudomonas tolaasii is a pathogen causing brown blotch disease in cultivated mushrooms. In previous study, various strains of P. tolaasii were isolated from the mushrooms with disease symptoms and they were further divided into Ptα, Ptβ, and Ptγ subtypes according to the 16S rRNA gene analysis. To investigate the secretion of peptide toxins, tolaasin and its analog peptides, culture extracts of Pt group strains were analyzed by gel permeation chromatography. Those of Ptα subtype strains contained two chromatographic peaks, band A and B. Meanwhile, those of Ptβ and Ptγ subtype strains contained mainly band A component and a little of band B. Molecular weights of toxic peptides of culture extracts were measured by MALDI-TOF mass spectrometry. In Ptα subtype strains, the peptide compositions of band A and B were same including tolaasin I (1,987 Da), tolaasin II (1,943 Da), and its two analog peptides, 1,973 Da and 2,005 Da. The strains of Ptβ and Ptγ subtype secreted many components of MW 1,100-1,200 Da, but they did not synthesize any tolaasin-like peptides. These results suggest that the only Ptα subtype strains secrete tolaasin and its analog peptide toxins and the strains of Ptβ and Ptγ subtypes have different pathogenic characters causing brown blotch disease.

Small libraries have continued to be extended since 2013 enactment of regulations requiring establishment of small libraries in multi family housing complex not less than 500 households and the 'Living SOC Project' of national government. Gwangmyeong city designated the year of 2020 as the 'year of citizen autonomy' sharing the authority with citizens and publicly announced its plan to rapidly extend the living and cultural spaces as a part of that extension. Likewise, as the social environment and the need of users are expected to change, it seems that the small libraries in Gyangmyeong City must prepare a plan for practicing a long and mid term practices in responding to that change. Thus, this Study tries to make a suggestion for a plan for the policy for revitalization of small libraries in order to handle those changing social environment and the need of users. For this, a survey and in-depth group interview were conducted for the operators of the small libraries in Gyangmyeong City. As a result of this Study, the following policies are suggested: first, improvement of support system for improving operational system, strengthening of cooperative system of public libraries, and strengthening of role of public small libraries, strengthening of public characters of private small libraties and differentiated support through evaluation based on abilities; and second, it is necessary for utilization of circulating librarians and professional volunteers, sharing of materials through mutual lending of books, associate librarians having term of office and revitalization of small library conference by regions.

The shipping industry has experienced significantly fluctuated while decline in long-term and boom in short-term period due to the continuous recession of the shipping industry since the 2010s and during the recent COVID-19 pandemic. This study aims to suggest implications for securing manpower and personnel policy by analyzing the effects of job environmental factors of a liner shipping company on job satisfaction and turnover intention and differences between land and marine workers. For the analysis, the job environmental factors of a liner shipping company were divided into work character, relational factors, personnel characters, and remuneration factors, and then structural equation model and t-test were conducted to test the relationship between job satisfaction and turnover intention. As a result of the study, it was found that job environmental factors, such as work, relationship, personnel, and remuneration, had a positive (+) effect on job satisfaction, and job satisfaction had a negative (-) effect on turnover intention. In a comparative analysis between groups such as land and sea workers, it was found that the maritime workers group had higher job satisfaction and lower turnover intention than the land workers.

The present study was conducted to investigate the variations in morphological traits, yield and yield-related components of rice cultivars exposed to different weather conditions by growing at the locations with different altitude but with equal latitude. Three Japonica varieties (Daegoldo, Jinheung, Shin #2) and three Tongil type semi-dwarf varieties(Josaengtongil, Suweon 287, wx 817-65-2-3) were seeded at Suweon on April 21 and transplanted at Suweon ($127^{\circ}$ N37 20', altitude 37m) and Jechun ($128.2^{\circ}$, N37 10', altitude 280-300m) on June 1 with the spacing of 30 $\times$ 15 em. The morphological traits, yield and yield-related components were measured. Culm length, paincle length and 1000-grain weight showed a little increase in Japonica varieties in Jechun as compared to those in Suweon and vice versa in semi-dwarf varieties, showing no significant differences. Number of panicles, per hill and number of spikelets per panicle among yield-related components showed remarkable increase in all varieties in Jechun as compared to those in 'Suweon but such inter-locational differences differed with varieties within varietal group and between varietal groups. On the contrary, grain fertility was higher in Suweon than that in Jechun and in Japonica varieties than that in semi-dwarf varieites , showing greater inter-locational difference in semi-dwarf varieties. Among Japonica varieties Jinheung and Shin #2 showed remarkable increase in yield in Jechun as compared to that in Suweon but in semidwarf varieties it was just the opposite. The importance of each of the yield-related component contributing to yield showed similar tendency 'regardless of locations in Japonica varieties. However, it was evidently different between locations in semidwarf varieties, where number of spikelets per panicle showed greatest direct effect on yield in Suweon but in Jechun so did grain fertility followed by the number of spikelets per panicle.

This study focuses on consumers' perceptions of virtual influencers, which many companies recently used for marketing. This study uses the Q methodology to derive what kind of perception consumers have about virtual influencers who work with various appearances, background stories, and worldviews as components. In addition, we want to see how the expected value of virtual influencers differs by age group. To this end, 34 statements were produced through preliminary interviews and literature reviews. This study showed that some consumers preferred appearances similar to humans, despite recognizing that virtual influencers are fictional characters. Some other consumers preferred to feel like a fictional character by maintaining virtuality, confirming that there are both opposite consumers. In addition, consumers expect virtual influencers to have consistency and expertise in the content field covered, and some consumers do not prefer to show an overly commercial appearance. This study will likely provide implications for companies that want to utilize virtual influencers in considering which ones to use for target customers in marketing activities.

Watermelon (Citrullus lanatus) is a non-seasonal, economically important, cucurbit cultivated throughout the world with Asia as a continent contributing the most. As part of the effort in diversifying watermelon genetic resources in the already cultivated group, this study was devoted to providing baseline data on morphological quality traits and health-beneficial phytonutrients of watermelon germplasm collections, thereby promoting watermelon research and cultivation programs. To this end, we reported morphological traits, citrulline, and arginine levels of watermelon genetic resources obtained from the gene bank of Agrobiodiversity Center, Republic of Korea, and discussed the relationship between each other. Diverse characteristics were observed among many of the traits. But, most of the genetic resources (>90%) were either red or pink-fleshed. Korean origin fruits contained intermediate levels of soluble solid content (SSC) while The USA, Russian, Tajikistan, Turkmenistan, Taiwan, and Uruguay originated had generally the highest levels of soluble solids. The citrulline and arginine contents using HPLC method were ranged from 6.9 to 52.1 mg/g (average, 27.3 mg/g) and 1.8 to 21.3 mg/g (average, 9.8 mg/g), respectively. The citrulline content determined using Citrulline Assay Kit was ranged from 6.5 to 42.8 mg/g (average, 27.0 mg/g). Resources with high citrulline and arginine levels contained low SSC. Whereas, red- and pink-colored flesh samples had less citrulline compared to yellow and orange. In addition to the profiling of morphological characters and phytonutrients, molecular marker characterization and identification of sources of resistance to diseases and pests are recommended for a more complete diversity analysis of watermelon genetic resources.

This study attempted to elucidate the ecological niches and influencing environmental factors of Quercus variabilis and Quercus acutissima, which are representative deciduous broad-leaved trees in Korean forests, taxonomically close and genetically similar, under climate change conditions. Under climate change conditions induced by increased CO₂ and temperature, soil moisture and nutrient environments were manipulated in four gradients. At the end of the growing, plants were harvested to measure growth responses, calculate ecological niches, and compare them with those of the control. Eperimental plants were grown for 180 days in a glass greenhouse designed with four gradients each for soil moisture and nutrient environments under climate change conditions induced by increased CO₂ and temperature. After harvesting, growth responses of leaf traits were measured, ecological niches were calculated, and these were compared with those of the control groups. Furthermore, the responses of the two species' populations were interpreted using principal component analysis(PCA) based on leaf trait measurements. As a result, under climate change conditions, the ecological niche breadth for moisture environment was broader for Quercus variabilis than Quercus acutissima, whereas for the nutrient environment, Quercus acutissima exhibited a broader niche breadth than Quercus variabilis. And the rate of change in ecological niche breadth due to climate change decreased for Quercus variabilis in both moisture and nutrient environments, while for Quercus acutissima, it increased in the moisture environment but decreased in the nutrient environment. Additionally, in terms of group responses, both Quercus variabilis and Quercus acutissima expanded their ecological niches under climate change conditions in both soil moisture and nutrient conditions, with Quercus acutissima exhibiting a broader niche than Quercus variabilis under nutrient conditions. These results indicate that the changes in leaf morphological characteristics and the responses of individuals reflecting them vary not only under climate change conditions but also depending on environmental factors.

The Middle Carboniferous Gabsan Formation is distributed in the Cheongrim area of southern Yeongwol and the Mt. Gachang area of Chungbuk Province. This study was carried out to investigate the lithological characters and geochemical composition of the limestones and to find out controlling structures of the limestones of the formation. The limestones of the Gabsan Formation are characterized by the light gray to light brown in color and fine and dense textures. The limestone grains are composed of crinoid fragments, small foraminfers, fusulinids, gastropods, ostracods, etc. Due to the recrystallization, some limestones consist of fine crystalline calcites. The chemical analysis of limestones of the formation was conducted to find out the contents of CaO, MgO, Al$_2$O$_3$, Fe$_2$O$_3$ and SiO$_2$. The content of CaO ranges from 49.78-60.63% and the content of MgO ranges from 0.74 to 4.63% The contents of Al$_2$O$_3$ and Fe$_2$O$_3$ are 0.02-0.55% and 0.02${\sim}$0.84% , respectively. The content of SiO$_2$ varies from 1.55 to 4.80%, but some samples contain more than 6.0%. The limestones of the formation can be grouped into two according to the CaO content: One is a group of which CaO content ranges from 49.78 to 56.26% and the other is a group of which CaO content varies from 59.36 to 60.38%. In the first group, the contents of Al$_2$O$_3$, Fe$_2$O$_3$ and SiO$_2$ range very irregularly according to the CaO content. In the second group, the values of MgO, Al$_2$O$_3$, Fe$_2$O$_3$ and SiO$_2$ are nearly same. Detailed structural analysis of mesoscopic structures and microstructures indicates the five phase of deformation in the study area. The first phase of deformation(D$_1$) is characterized by regional scale isoclinal folds, and bedding parallel S$_1$ axial plane foliation which is locally developed in the mudstone and sandstone. Based on the observations of microstructures, S$_1$ foliations appear to be developed by grain preferred orientation accompanying pressure-solution. During second phase of deformation, outcrop scale E-W trending folds with associated foliations and lineations are developed. Microstructural observations indicate that crenulation foliations were formed by pressure-solution, grain boundary sliding and grain rotation. NNW and SSE trending outcrop scale folds, axial plane foliations, crenulation foliations, crenulation lineations, intersection lineations are developed during the third phase of deformation. On the microscale F$_3$ fold, axial plane foliations which are formed by pressure solution are well developed. Fourth phase of deformation is characterized by map scale NNW trending folds. The pre-existing planar and linear structures are reoriented by F$_4$ folds. Fifth phase of deformation developed joints and faults. The distribution pattern of the limestones is mostly controlled by F$_1$ and F$_4$ folds.

This study has been examined characteristics of Yeoju Lee family, rich group at Miryang in the middle of the Joseon Dynasty, around Geumsidang(今是堂) Lee Gwang-jin remains as a cultural landscape appeared in pictures, poetry, and a strange story. Geumsidang Lee Gwang-jin returned to his old home abandoned the middle government post after the death of Moonjeong queen in socially confused stage and tried to manage an annex to a Geumsidang located in Baekgok of Eungchun riverside, and Geumsidang he managed was affected by his teacher and uncle Wolyoun Lee Tae of a view of nature, filial behavior, and nature management etc. Also, 'Painting of 12 landscapes to Geumsidang' is landscape painting with the actual view not like the '8 landscapes of So-Sang' or '8 landscapes of Sa-Si' which is abstract landscape and Lee Gyeong-hong drew 12 landscapes of Geumsidang that includes Angbong(鶯峰: nightingale peak), Yongdu mountain(龍頭山), Mubong Buddhist temple(舞鳳寺), Maam mountain(馬巖山), Wolyeon-dae(月淵臺), Saindang village(舍人堂村), Youngnam-ru(嶺南樓), Miryang eubseong(密陽邑城), Eyeonso(梨淵沼: pear tree deep water), Yullim(栗林: chestnut tree forest), Miryang river(密陽江), Sammundong fields(沙門野), land and government office owned by Yeoju Lee family as landscape objects. 'Poems of 12 landscapes to Geumsidang' by Lee Yong-gu 11th sons of Lee Gwang-jin was written based on 'Painting of 12 landscapes to Geumsidang', and sang for time, season, and changes of the weather. All 12 poems are all a quatrain with seven Chinese characters in each line consisted of all 28 words, but does not match completely with shown elements in pictures because it is not a simple description of pictures but it is recreated by writer's personality. Therefore these painting shows not only th meaning of filial behavior but also village owned by Yeoju Lee family rich group in Miryang, and these poem recreated the pictures by changing as certain scenic spot with the object of enforcing territory of Yeoju Lee family.
