Environmental factors and phragmites growth properties at various habitats in Eulsukdo ecological park were investigated to understand major factors affecting phragmites distribution in constructed wetlands. Although phragmites is very important species in wetland ecosystem, it should be controlled to prevent excessive expansion within the restricted park area. The results showed that phragmites dominant sites have the highest LAI among other emerged plants habitats and could adversely affect for waders habitats. Phragmites were also found at the areas with wide ranges of water-depth than other plants, and showed phragmites could be favored for occupying the newly constructed wetlands like Eulsukdo ecological park. The results showed difference in soil redox potential between phragmites dominant and non-dominant sites. Because soil redox potential is affected by wetland hydrology like flooding duration, control of wetland hydrology should be considered for creation and management of constructed wetlands. The results also showed that differences in soil cation exchange capacity, soil salinity, soil organic matter content and site inclination between phragmites dominant and non-dominant sites as well as brackish and freshwater areas. Those abiotic factors can be important considerations for the sustainable wetland management especially for the phragmitest managements in the ecological park.

The various promotion countermeasures such as solidification, carbonization, and the creation of cement materials have been considered to existing treatment methods such as incineration and the creation of composts, since direct landfill was prohibited for encouraging the recycling based on the sludge treatment on land. The Main objective of this study is to investigate the feasibility of co-incineration for MSW (Municipal Solid Waste) and SS (Sewage Sludge) through the change of heat and atmospheric pollutants. In this study, LHV (Low Heating Value) is 100~300 kcal/kg because the MC (Moisture Content) of de-hydrated sewage sludge is approximately 80%. From the results, we knew the feasibility of co-incineration for MSW (80%) and SS (20%). As the co-incineration rate of SS up to 20% became higher, the loading of heat and atmospheric pollutants was not influenced.

In this paper, the design and implementation of an automatic reference-citation-mark attachment system are introduced. The system automatically attaches a citation mark to the end of a sentence in a technical document if the corresponding statement has a high similarity to another statement in the same document; simultaneously, the corresponding bibliographic data is automatically created from the cited-document information. In accordance with functional specifications, a Web-based, online service model and the development of its prototype system are proposed. The developed system can help in the elimination of unexpected plagiarism issues, and will alleviate the burdens of reference citation and reference-list creation for technical writers.

In this paper, I examined specific characteristics of the Tables of Transactions for Records Scheduling(TRS) (記錄物分類基準表 ; Kirokmul-Bulyukijun - Pyo) system by Public Records and Archives Act(PRA Act, No. 5709, 1999). All staffs and employees in governmental agencies of Korea must register, classify and dispose of their official records according to TRS by the Presidential Regulation for the application of PRA Act(No. 17050, 2000). Namely, the criteria of TRS is applicable to all stages of records lifecycle from creation to disposition(transfer to Archives or legal destruction). In the theoretical and methodological area, therefore, it is absolutely important that records managers and archival professionals in Korea make analysis on functions and characteristics of TRS by PRA Act. In the first, my examination take notice of possibility of 'adequate and proper documentation' about activity of the executive organization in TRS system. Other attention is that records management according to TRS means managing of records not only as physical entities but as logical entities which imply content and context of creation and use. In other hand, I wish to account for reasonable separation consideration for continuing utility of archives from current use of records throughout agencies duration Another theme of discussion in this paper is the theoretical framework which give account of TRS's characters. In conclusion, accountability for characteristics of TRS system could have been found in counterproposal view including the concept of Records continuum and the notion of Recordkeeping regime in Australia based on rethinking about Records lifecycle model. In the extent of practical area, more or less, it is imbalanced method that compare TRS by PRA Act to Recordkeeping regime based on Records continuum. Nevertheless, the concept and notion is suitable framework that give account of the prospect of recordkeeping system under PRA Act.as well as the meaningful characteristic of TRS.

In this study, activity of anti-oxidation of Cinnamomum loureiroi extract (CLE). In order to measure anti-oxidation effect of CLE, phenol content of CLE, radical scavenging activity of ABTS and DPPH, and decrease of ROS production. Before the experiment, against Raw 264.7 cell, a cytotoxicity was measured and the result showed no toxicity. CLE's total polyphenol amount was 397.7±8.3 mg/g and the total flavonoid amount was 101.899±0.885 mg/g. As a measurement result of ABTS radical scavenging ability and DPPH radical scavenging ability, radical scavenging ability increased depends on the concentration. CLE's effect on the ROS creation was checked and the result showed that CLE suppressed ROS creation by showing a meaningful decrease of ROS generation. From all of the results, CLE is know to have an antioxidant effect. These results will be provided as fundamental data for further development of the new material of functional cosmetics to the results above.

Despite the growing educational demand for the extended reality (XR) convergence content creation for non-IT students, fewer studies have attempted to education material development. In this paper, non-IT students' requirement to create XR convergence contents was analyzed and designed framework system specification. The object-oriented application framework (OOAF) was developed for non-IT students to create XR convergence contents through simple interaction methods such as drag and drop in-game engines. To evaluate the developed framework XR contents development course was operated with 26 industrial design majors sophomore in university. More than 90% of students succeeded in working on prototype XR contents in Oculus Rift. This result will be expected to improve the quality of XR contents creation education for non-IT students and contribute to the growth of the future convergence contents industry.

One More Pumpkin won the grand prize at the 2023 Dubai International AI Film Festival, and new possibilities were also opened through the International AI and Metaverse Film Festival (GAMFF), which was held for the first time in Korea. Generative works began to stand out in earnest, with 527 diverse works from 42 countries at home and abroad using AI and metaverse technology submitted to this contest. AI is being used in a variety of fields, including the creation and implementation of digital characters through combination with VFX, improving the efficiency of video production, and managing the overall video production process. This contributes to saving human and material resources required for production and significantly improving the quality of produced videos. However, generative AI also has ambiguity in copyright attribution, ethical issues inherent in the learned dataset, and technical limitations that fall short of the level of human emotion and creativity. Accordingly, this study suggests implications at the level of production, screening, and use, as generative AI may have an impact in more areas in the future.

Chinese cartoon industry lately was able to see a rapid development which changed cartoon creative personnel associated with increased production technology development, new technologies, government support policy and a variety of environments. It was likely to have high expectations for changes in the policy environment of the country supported the comic creators and authors to develop its own comic industry. The State Administration of Press, Publication, Radio, Film and Television of China promoted the production for the development of Chinese animation with "domestic little video about the development of the animation industry's opinion", and "documents Documents". Animation industrial base and animation education was established in institutions such as the organization one after another. In the meantime, the spread of Japanese comics picture on the creative activation admitted but their comic creation and activation was slump. It would produce that the creation of its traditional culture based activation strategy to built comics. Since 2004, It was well represented for the creators of the cartoon creation of the tradition and uniqueness of Chinese history. In the prior to 2004, comics and strategies was to be differentiated. Today, China is an important source of comic marked the fact that the tradition was recognized and it was further developed with combining creativity of the past and the present production system. Comic creators comic story of traditional culture were excavated in order to have a sense of awareness and modern. The difference between China Cartoon and comics in other Asian countries is true that cartoon story came out naturally in a traditional culture. In this study, It would lead in the future to allow directional presented for the digital cartoon making development policy awareness through the comic creation and production of new media content industry enabled to China. Now, in the new media industry for the development of China's neighboring countries coped with climate change for the active exchange of information. It poured out ceaseless technical development and a range of policies to support business expansion. New China Cartoon was leaped to re-fit the industry.
