목적: 본 연구는 감각통합 평가 도구인 Sensory Profile 2 (SP-2)의 해석 복잡성, 주관성, 시각화 한계를 개선하기 위해 인공지능(artificial intelligence) 기반 챗봇(ChatBot) 시스템인 Sensory Profile 2 Summary and Interpretation (SPSI)를 개발하고 그 활용 가능성을 탐색하였다. 방법: SP-2의 평가 항목과 점수 산출 방식을 기반으로 자동화된 ChatBot 인터페이스를 구현하였으며, 자연어 기반의 문답 시스템을 통해 사용자가 직관적으로 평가에 참여할 수 있도록 설계하였다. ChatBot은 자동 점수 산출, quadrant grid/score별 해석, 중재 전략 제시, 시각적 요약 등의 기능을 포함하고 있으며, OpenAPI 연동을 통해 다양한 출력 형태를 지원한다. 결과: SPSI는 평가자의 주관 개입을 최소화하면서도 일관된 해석과 전략 제시가 가능하며, 시각화 자료(파이차트, 행동 예시 등)를 통해 보호자 및 비전공자에게도 직관적인 결과 전달이 가능하였다. 특히 설문 입력에서 결과 도출까지의 전 과정을 자동화함으로써 평가 소요 시간과 해석 부담을 줄이는 데 기여할 수 있다. 결론: SPSI는 작업치료 분야에서 기존 감각통합 평가 도구의 한계를 보완할 수 있는 사용자 중심의 디지털 평가 도구로서의 가능성을 보여주었다. 향후에는 임상적 유용성을 확보하기 위해 신뢰도 검증, 설명 가능한 인공지능(explainable artificial intelligence) 도입, 보안 체계 강화 등의 보완이 필요하다.

This study aims to reinterpret the concept of mimesis within a digital context and propose a prototype design for a web-based performance simulation platform. The proposed platform is designed to enable stage directors to pre-visualize elements such as stage setup, actor movements, sound, and lighting within a virtual environment, thereby enhancing the efficiency and creativity of performance planning. The prototype was designed to enable interaction among performance elements by incorporating 3D modeling of a proscenium stage, integrating motion-capture-based FBX data, and utilizing timeline-based control. Furthermore, it features a real-time 3D rendering architecture leveraging Three.js and WebGL, allowing it to run seamlessly in a web browser without additional plugins. This research is significant as it establishes a conceptual foundation demonstrating the potential for integrating performing arts with digital technology. Future research should involve practical implementation and field validation to confirm its real-world utility.

Since the small screen must be watched at the production and manufacturing site, when using the monitor without a separate paper for work and production instructions, it is necessary to look at the work instruction screen installed in a separate space to prevent work efficiency from deteriorating. It plays a role through a monitoring system using DPS or Barcode and RF-ID recognition as a safety device for installing heterogeneous parts in manufacturing and missing parts, but due to the high cost of introducing the system and difficulty in maintaining management, Visual POP is put into the production line. This study was produced by paying attention to the following five points in order to reduce the weight of these industrial Visual POPs and have global specifications and uses. These include instrument design and design, processing production, UI and control, application, thermal stress analysis and thermal analysis. In this study, it is considered to thermal stress analysis and thermal analysis of Visual POP for Models 1 and 2.

The AlSi10Mg alloy has garnered significant attention for its application in laser powder bed fusion (L-PBF), due to its lightweight properties and good printability using L-PBF. However, the low production speed of the L-PBF process is the main bottleneck in the industrial commercialization of L-PBF AlSi10Mg alloy parts. Furthermore, while L-PBF AlSi10Mg alloy exhibits excellent mechanical properties, the properties are often over-specified compared to the target properties of parts traditionally fabricated by casting. To accelerate production speed in L-PBF, this study investigated the effects of process parameters on the build rate and mechanical properties of the AlSi10Mg alloy. Guidelines are proposed for high-speed additive manufacturing of the AlSi10Mg alloy for use in automotive parts. The results show a significant increase in the build rate, exceeding the conventional build rate by a factor of 3.6 times or more, while the L-PBF AlSi10Mg alloy met the specifications for automotive prototype parts. This strategy can be expected to offer significant cost advantages while maintaining acceptable mechanical properties of topology-optimized parts used in the automobile industry.

To produce an intestinal immunomodulatory beverage containing Centella asiatica extract (CAE), three types of CAE-added beverage prototypes were prepared, and their immunomodulatory activities and marker compounds were analyzed. As a result of the cytotoxicity assessment, all the beverages did not show significant toxicity compared to the control group. Next, the immunomodulatory activities of the beverage prototype were evaluated using the inflammatory model of IL-1β-induced intestinal epithelial cell line. All the samples significantly reduced the production of IL-6, IL-8, and MCP-1 in a CAE concentration-dependent manner. In addition, CAE-added beverages inhibited NO, IL-6, and IL-12 production in LPS-induced RAW 264.7 cells. When the major triterpenoids, as marker compounds for the production of CAE-added beverages, were analyzed by HPLC-DAD, only asiaticoside was detected beyond the limit of quantification, while madecassoside, madecassic acid, and asiatic acid were not detected. The amounts of asiaticoside in CAE-added beverage prototypes were confirmed in No. 1 (19.39 μg/mL), 2 (19.25 μg/mL), and 3 (19.98 μg/mL). In conclusion, the results of this study suggested that CAE-added beverage prototypes induced immunomodulatory effects in the intestinal inflammatory cell line models and asiaticoside could be used as a marker compound for CAE-added beverage production.

Streaming media is an emerging mode of video playback. It compress a series of multimedia data and transmit the data in real time through the Internet. And It has become an important part of people's daily entertainment and leisure. These streaming media platforms(Including OTT platforms) are full of enormous Intellectual Property(IP). Although there are some original IP, most of them are derived from Chinese classical culture and refreshed vigorously. Owing to digitalization, paper publications gradually broken the restrictions of physical forms and evolved to multiple digital forms in the world. In the thriving contemporary cultural industry, the needs for traditional classics are gradually surpassing that for the pure humanistic value, and thus the culture industry value of them are focused on. Xiyouji is the crystallization of the collective wisdom and imagination of the ancient folk, which has been active in people's daily life with various forms of popular cultural products, such as speech and opera, since the ancient time. Therefore, Xixingji is selected in to this paper as the study object, so as to discuss how the original work is effectively untilized in Xixingji to create the magnificent script and storylines and how Christopher Vogler's narratological theory is adopted to analyze the storytelling and character in animation Xixingji, and also to investigate the market reaction of Xixingji in China and South Korea.

본 연구에서는 비닐멀칭된 외두둑에서의 배추 수확을 위한 시작기(A, B-1, B-2)를 설계 및 제작하였고, 시험을 통해 배추 수확을 위한 인발 장치부, 절단 장치부, 이송 장치부 등의 작업공정별 성능과 전체 작업성능을 분석하였다. 이론 분석을 통해 작업속도 0.2 m/s, 이송 벨트 각도 20∼35°, 이론적 이송 벨트의 적정 이송 속도를 작업속도보다 1.5배 빠르게 설정하여 청풍 및 춘광 품종을 대상으로 현장시험을 실시하였다. A형 시험 결과, 인발⋅이송성능은 성공률이 50% 수준으로 낮았으며, 절단성능의 경우 배추의 상품성이 양호한 경우가 35%, 과절단된 경우가 10% 및 미절단된 경우가 55%로 전반적으로 배추의 절단상태가 불량하였다. B형 시험 결과, 스핀들 인발장치는 비닐멀칭된 두둑에서는 감김현상으로 작업이 불가하였으며, 비닐멀칭없는 두둑에서의 인발⋅이송성능은 성공률이 78% 수준으로 A형보다 높아졌으나, 절단성능의 경우 배추의 상품성이 양호한 경우가 7.7%, 과절단된 경우가 15.4% 및 미절단된 경우가 76.9% 로 오히려 배추 절단상태는 더욱 불량해진 것으로 나타났다. 본 시작기의 비닐멀칭된 두둑에서의 현장시험 결과, 배추 인발, 절단 및 이송성능이 불량하게 나타나 인발, 절단, 이송작업에서의 전반적인 구조개선이 필요한 것으로 판단되었다.
