This paper presents the technique on structuring information of the diagram repository for UML diagrams. Because object interactions are the body of object-oriented programming, this paper handles especially the sequence diagrams and class diagrams among UML diagrams. Based on class diagrams, sequence diagrams represent the procedure of object interactions in run-time and then the corresponding codes are generated from the contents of those sequence diagrams. To do this work, this paper presents a method to construct the information repository for generating code from the contents of sequence diagrams. This paper classifies the five message types of sequence diagrams and then extracts the needed information including items and values on the corresponding message types for constructing message repositories. Because sequence diagram is composed of messages included, the final repository is constructed by collecting each of structured repositories on messages sequentially.

This paper aims to show the development pattern of the impact of artificial intelligence on the arts and culture according to the scenario analysis, and suggests the direction of the arts and culture content industry in the future. We assume four scenarios based on creativity of artificial intelligence beyond humans and controllability for them, then explore the path leading to each scenario. In addition, for the most ideal route to coexist with artificial intelligence, we propose the provision of safety system for human and artificial intelligence, innovation of the education system, and preemptive investment from now on.

The air-dried bark of Salix rorida was extracted with acetone-water(7:3, v/v) and its extractives were concentrated with a vacuum evaporator. The extractives were fractionated with a series of n-hexane, chloroform, ethylacetate(EtOAc) and water on a separatory funnel. Each fraction was freeze-dried to give some dark brown powder. The EtOAc and water soluble fractions were chromatographed on a Sephadex LH-20 column using a series of aqueous methanol and ethanol-hexane mixture as eluents. The isolated compounds were tested with a cellulose TLC developed with TBA and 6% acetic acid and then visualized on UV lamp or sprayed with vanillin-HCl-EtOH. The purified compounds were flavonoids and their glycosides as follows:(+)-catechin, naringenin, salipurposide, aromadendrin, isosalipurposide, aromadendrin-7-O-𝛽-D-glucopy- ranoside and taxifolin-7-O-𝛽-D-glucopyranoside. The structures of each compounds were confirmed by ¹H-NMR, ¹³C-NMR and mass spectra.

Data required in a wireless sensor network environment requires more accurate figures as technology advances and its complexity increases. However, in the case of operating a large number of sensor nodes in a large area, the balance between the power consumed and the data quality that can be acquired accordingly should be considered for that purpose. In particular, in complex, densely populated urban areas or military operations with specific goals, location data requires increasingly detailed and high accuracy over a wide range. In this paper, we propose a method of mounting a Global Positioning System(: GPS) only on some of the sensor nodes deployed in the wireless sensor network and improving the error of GPS location data measured on that sensor node through Angle of Arrival(: AoA) and Received Signal Strength Indicator(: RSSI).

The 2020 Gwangju Media Art Festival (2020 GMAF) was held in the area of the National Asian Cultural Center. Under the slogan "The entire Gwangju shines under the theme of "Aesthetics of Light and Coexistence," the media festival demonstrated projection mapping to Jeonnam (former) Provincial Office at the DATA+ Research Institute of Chung-Ang University's Graduate School of Advanced Video. This paper focuses on explaining the overall production process and content development of projection mapping demonstrated in the Jeollanam-do Provincial Government, which is a symbol of Korean democratization and is located in the center of Gwangju, Jeolla-do. It was intended to faithfully express the history of the 2020 GMAF and Jeonnam (former) provincial government, Gwangju's history, and democratization records. It was intended to show images, background sounds, sound effects, and visual effects using various special effects and high-power laser devices using unique characteristics of projection mapping. To this end, about 5 minutes and 30 seconds of content were planned, and it was divided into parts and topics, and one individual story was developed for each chapter.

This research is to make the identity of the two models clear by reviewing the similarities and differences between Social Model of Disability from U.K. and Independent Living Model from United States. Research results are as follows. As for differences, Social Model of disability intended to change disability paradigm by focusing society itself as the cause of disability rather than individuals, however Independent Living Model stressed on the freedom and control through disabled people's life with self-advocacy group and personal assistants. As for similarities, there are self-representatives, social responsibility for disability, alienation of people with intellectual disabilities at the initial stage, background in legislating Disability Discrimination Acts in both countries. This result has its significances because it shows theoretical framework which make it possible to review further how disability practice and movements understand the two models regardless of their real contents and how the two affected the induction and proceeding of Korean Discrimination Act and Independent Living Paradigm in the Disability Welfare Act.

This is a comparative and analytical study which comprises of the analysis of the rules of the seller's liability for non-conforming goods of four legal systems under the CISG and the CESL. A purpose of this study is to examine all the rules as to, first, the concept and the nature of the seller's duty to deliver the goods in conformity with the contract, second, the contents of the seller's duty to deliver the goods in conformity with the contract, third, the time when the goods must be in conformity with the contract and the cases where the seller is exempted from his liability for non-conforming goods. Another purpose is to compare the rules of the CISG with those of the CESL, and to evaluate them in light of the discipline of comparative law. This is for the purpose of facilitating the systematic development and reform of one jurisdiction by any solution from the other jurisdiction found by the comparative study. In addition, this study provides legal and practical advice to the contracting parties when they intend to use one of those regimes in their contract as a governing law.

In line with the modern society where artificial intelligence has spread throughout society, the Ministry of Education decided to provide AI education in kindergartens, elementary, middle and high school classes in 2025, and develop related learning materials and textbooks from 2021. Korea currently does not have state-led AI education for kindergarten and elementary school, so there is no systematic teaching material. Therefore, this study designed and presented textbooks for pattern analysis-based computational thinking development based on the GPS curriculum, a kindergarten SW curriculum studied by Y. S. Jeong and S. E. Lim (2020). Class procedures for using the textbooks were classified as introduction activities, development activities, and organization activities. Supplementary explanations were presented by presenting textbooks and teaching aids along with explanations of each activity. In order for this study to help AI education conducted in 2025, research must be conducted to demonstrate its effectiveness through actual application in the future.
