This study, To find practical problems with the imaging of webtoons, propose their alternatives, and secure the professionalism of research along with 22 field experts including writers, directors, producers, investors and importance survey was carried out with 30 practical experts. There were four major interview areas including the stages of imaging production, investment and support for imaging, difficulties with imaging, and improvement of production methods and systems. Responses were collected from a total of 13 questions. All agreed that the biggest difficulty with imaging was a low level of collaboration, but they had different ideas about an ideal collaboration system. A low level of collaboration was mainly attributed to a shortage of professionals and lack of communication. There should be an effort to bring up such experts in three major areas including professional adaptation writers, professional IP producers, and investment agencies specialized in content.

Polyploidization plays an important role in generating the current high diversity of plants. Studies of the distributional patterns of diploid and derivative polyploid races have provided important insights into the evolutionary process and cryptic speciation by polyploidization within and between closely related taxa defined on the basis of their morphology. Allium thunbergii and A. sacculiferum, occurring throughout eastern Russia, eastern China, Korea, and Japan, are examples of closely related species with unsolved taxonomic relationships. A total of 97 and 65 individuals from 26 and 13 populations of A. thunbergii (including var. thunbergii, var. deltoids, and var. teretifolium) and A. sacculiferum, respectively, were studied to determine their ploidy. The geographic structure and habitat differentiation of the cytotypes were also analyzed. The main cytotype of A. thunbergii was diploid (92.3% in total; the rest were tetraploids). In contrast, the majority of A. sacculiferum plants were tetraploids (69.2% of the total; the rest were diploids). No populations of the studied taxa harbored both cytotypes. Allium thunbergii was more often found at higher elevations than A. sacculiferum, and it tended to occur more frequently on rocky slopes and below forests in mountainous areas. On the other hand, A. sacculiferum occurred at forest margins and in lowland pastures. The cytotypes differed with respect to the elevation; diploids were found more frequently at higher elevations than tetraploids. The results of this study and additional biosystematics data indicate that the morphological characteristics of A. thunbergii and A. sacculiferum may be influenced by polyploidization and by their adaptation to various habitat conditions and that A. thunbergii and A. sacculiferum do not clearly fulfill the requirements of any species concept. Consequently, we propose that A. sacculiferum be considered as an additional synonym of A. thunbergii. Additionally, Allium thunbergii var. deltoides is unified into A. thunbergii var. thunbergii.

This paper evaluates the performance of CCA (Compact Constellation Algorithm) adaptive equalization algorithm by varying the step size for minimization of the distortion effect in the communication channel. The CCA combines the conventional DDA and RCA algorithm, it uses the constant modulus of the transmission signal and the considering the output of decision device by the power of compact slice weighting value in order to improving the initial convergence characteristics and the equalization noise by misadjustment in the steady state. In this process, the compact slice weight values were fixed, and the performance of CCA adaptive equalization algorithm was evaluated by the varing the three values of step size for adaptation. As a result of computer simulation, it shows that the smaller step size gives slow convergence speed, but gives excellent performance after at steady state. Especially in SER performance, the small step size gives more robustness that large values.

The purpose of this case study was to examine how a supportive songwriting program could facilitate resilience for adolescents with school maladjustment. Participants included four middle school students with adaptive difficulties. The participants received eight 50-minute sessions of a supportive songwriting program. The program consisted of singing and discussing selected songs, followed by the participants creating their own lyrics about their current adaptation issues. The Resilience Scale for Adolescents was completed by each participant before and after the intervention, and the participants' lyrics were analyzed for how the factors of resilience were reflected in their lyrics. The results showed that all participants' scores on the resilience scale increased. It was also found that the factor on the resilience scale that increased the most for each participant was related to the issues expressed in their lyrics. The results suggest that the process of writing songs can be effective in eliciting adolescents' school related issues and accessing their positive resources, which can lead to behavioral and psychological improvements.

Compound disaster is the type that increases the impact affected by two or more hazard events, and attention to compound disaster and multi-hazards risk is growing due to potential damages which are difficult to predict. The objective of this study is to analyze the possible impacts of post-fire landslide scenario quantitatively by using TRIGRS (Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability Analysis), a physics-based landslide model. In the case of wildfire, soil organic material and density are altered, and saturated hydraulic conductivity decrease because of soil exposed to high temperature. We have included the change of soil saturated hydraulic conductivity into the TRIGRS model through literature review. For a case study, we selected the area of $8km^2$ in Pyeongchang County. The landslide modeling process was calibrated before simulate the post-wildfire impact based on landslide inventory data to reduce uncertainty. As a result, the mean of the total factor of safety values in the case of landslide was 2.641 when rainfall duration is 1 hour with rainfall intensity of 100mm per day, while the mean value for the case of post-wildfire landslide was lower to 2.579, showing potential landslide occurrence areas appear more quickly in the compound disaster scenario. This study can be used to prevent potential losses caused by the compound disaster such as post-wildfire debris flow or landslides.

Environment, food, and disease have a selective force on the present and future as well as our genome. Adaptation of livestock and the environmental nexus, including forest encroachment for anthropological needs, has been proven to cause emerging infectious diseases. Further, these demand changes in meat production and market systems. Meat is a reliable source of protein, with a majority of the world population consumes meat. To meet the increasing demands of meat production as well as address issues, such as current environmental pollution, animal welfare, and outbreaks, cellular agriculture has emerged as one of the next industrial revolutions. Lab grown meat or cell cultured meat is a promising way to pursue this; however, it still needs to resemble traditional meat and be assured safety for human consumption. Further, to mimic the palatability of traditional meat, the process of cultured meat production starts from skeletal muscle progenitor cells isolated from animals that proliferate and differentiate into skeletal muscle using cell culture techniques. Due to several lacunae in the current approaches, production of muscle replicas is not possible yet. Our review shows that constant research in this field will resolve the existing constraints and enable successful cultured meat production in the near future. Therefore, production of cultured meat is a better solution that looks after environmental issues, spread of outbreaks, antibiotic resistance through the zoonotic spread, food and economic crises.

This study is to investigate the mediating effects of social support on the relationship between acculturative stress and mental health of multicultural youth. The results of the study were as follows: 1.573 of the 4th(middle 1) to 6th(middle 3) of the multicultural youth panel were analyzed by AMOS 22.0. First, the acculturation stress of multicultural youths had a positive effect on mental health. Second, acculturation stress of multicultural youths had a negative effect on social support. Third, social support of multicultural youths had a negative effect on mental health. Fourth, social support of multicultural youths had a mediating effect on the effect of acculturation stress on mental health. This result shows that the stress of multicultural youths in the process of adapting to the dual culture negatively affects social support, and this social support has a positive effect on the mental health of multicultural youths.

The concern on the greenhouse gas emission is strongly increasing globally. In fishery industry section, the greenhouse gas emissions are an important issue according to The Paris Climate Change Accord in 2015. The Korean government has a plan to reduce the GHG emissions as 4.8% compared to the BAU in fisheries until 2020. Furthermore, the Korean government has also declared to achieve the carbon neutrality in 2050 at the Climate Adaptation Summit 2021. However, the investigation on the GHG emissions from Korean fisheries did not carry out extensively. Most studies on GHG emissions from Korean fishery have dealt with the GHG emissions by fishery classification so far. However, follow-up studies related to GHG emissions from fisheries need to evaluate the GHG emission level by species to prepare the adoption of environmental labels and declarations (ISO 14020). The purpose of this research is to investigate which degree of GHG emitted to produce the species (hairtail and small yellow croaker) from various fisheries. Here, we calculated the GHG emission to produce the species from the fisheries using the Life Cycle Assessment method. The system boundary and input parameters for each process level are defined for the LCA analysis. The fuel use coefficients of the fisheries for the species are also calculated according to the fuel type. The GHG emissions from sea activities by the fisheries will be dealt with. Furthermore, the GHG emissions for producing the unit weight species and annual production are calculated by fishery classification. The results will be helpful to understand the circumstances of GHG emissions from Korean fisheries.

Objectives: This study was carried out in order to evaluate the overall process that the caregiving stress of parents of adult children with developmental disabilities affected their life satisfaction through the levels of family resilience, and coping styles on the basis of stress-coping-adaptation model of Lazarus and Folkman(1984). Method: For this purpose, the structured survey was conducted by 394 parents of adult children with developmental disabilities. The data was analysed by AMOS 20.0 version. Results: The findings can be summarized as follows: First, the structural equation model(SEM) analysis was conducted in order to examine the various paths that parents' caregiving stress affected their life satisfaction. The model's goodness-of-fit was fine($x^2=225.20$, df=95, p=000. RMSEA=.06, TLI=.95). There were significant relationships between caregiving stress and family resilience(${\beta}=-.36$, p<.001), emotion-focused coping style(${\beta}=.47$, p<.001), life satisfaction(${\beta}=-.53$, p<.001). Second, family resilience and emotion-focused coping showed mediating effects on the relationship between caregiving stress and life satisfaction. Conclusions: The strategies for enhancing family resilience and social services for applying effective coping methods should be expanded in order to diminish the caregiving stress of parents of adult children with developmental disabilities.

Our investigation of the intricate relationship among nationalism, humanism, and imperialism begins from reading Song of Ariran, the auto/biography of Kim San recorded by Nym Wales, together with Margaret Drabble's fictional adaptation of Lady Hong's autobiography, The Memoirs of Lady $Hyegy{\breve{o}}ng$, in her novel The Red Queen, in which the story of Barbara Halliwell, a modern female envoy of Lady Hong, is interweaved with Lady Hong's narrative. In spite of their being seemingly disparate texts, Song of Ariran and The Red Queen are comparable: they are written by Western female writers who deal with Koreans, along with the Korean history and culture. Accordingly, both works cut across the boundary of fiction and fact, imagination and history, and the East and the West. In the age of globalization, Western women writing (about) Korea and Koreans traversing the historical and cultural limits inevitably engage us in post-colonial discussions. Despite the temporal differences--If Song of Ariran handles with the historical turmoils of the 1930s Asia, mostly surrounding Kim San's activities as a nationalist, The Red Queen is written by a twenty-first century British woman writer whose international interest grapples with the eighteenth-century Korean Crown Princess' spirit in order to reinscribe a story of Korean woman's within the contemporary culture--, both works appeal to the humanistic perspective, advocating the universal human beings' values transcending the historical and national limitations. While this sort of humanistic approach can provide sympathy transcending time and space, this 'idealistic' process can be problematic because the Western writers's appropriation of Korean culture and its history can easily reduce its particularities to comprehensive generalization, without giving proper names to the Korean history and culture. Nonetheless, the Western female writers' attempt to find a place of 'contact' is valuable since it opens a possibility of having meaningful communications between minor culture and dominating culture. Yet, these female writers do not seem to absolutely cross the border of race, gender, and culture, which leaves us to realize how difficult it is to reach a genuine understanding with what is different from mine even in these 'universal' narratives.
