시리즈 애니메이션 IP들이 사업 다각화를 위해 웹툰으로 제작되어 서비스되는 경우들이 있는데, 영세한 애니 메이션 제작사들은 웹툰으로 제작할 때 발생하는 노동집약적인 작업 과정과 비용 때문에 접근이 어려운 실정 이다. 이를 위해 함께 협업한 연구실에서 인공지능을 활용하여 <Pitchfork Park> 애니메이션 시리즈의 웹툰 변 환 작업을 자동화하는 시스템을 개발하였다. 해당 시스템을 활용하면 단순 노동적으로 작업자가 일일이 수행 하던 1) 애니메이션 컷 선별, 2) 선별된 컷 재배치, 3) 말풍선 배치, 4) 대사 배치, 5) 효과선 추가 등 상당 부 분을 자동화할 수 있다. 시스템에서 출력된 작업물을 작업자가 확인하고, 후보정 작업을 거쳐 최종 결과물을 완성한다. 기존 작업 과정에서 필요한 노동력과 시간을 절약할 수 있고, 작품의 완성도도 향상시킬 수 있다. 본 연구는 기존 웹툰 작업 과정을 분석하여 인공지능을 활용한 작업 방식의 효율성을 검증하였으며, 결과적으 로 인공지능 기술을 활용한 애니메이션의 웹툰 변환 제작 파이프라인을 구축할 수 있는 토대를 확인하였다.

To investigate the anti-inflammatory activity of submerged culture using Cordyceps militaris mycelium, culture-including mycelia was extracted and lyophilized into postbiotics (hot-water extract; CM-HW). HW was fractionated into crude polysaccharide (CM-CP) by ethanol precipitation, and CM-CP was further dialyzed into CM-DCP by dialysis with running water using 12~14 kDa dialysis tube. When the cytotoxicity of subfractions against cells was assessed, no subfraction had a cytotoxic impact that was substantially different from the control groups. In an inflammatory model using LPS-stimulated RAW 264.7 cells, CM-DCP significantly decreased IL-6 and MCP-1 production levels compared to the LPS-control group. CM-DCP also inhibited IL-6 and IL-8 secretion in HaCaT keratinocytes stimulated with TNF-α and IFN-γ. In the meanwhile, the neutral sugar content and mannose ratio of anti-inflammatory CM-DCP were higher than the other fractions, and CM-DCP contained β-1,3/1,6-glucan of 216.1 mg/g. High pressure size exclusion chromatography revealed that CM-DCP contained molecules with a molecular weight range of 5.6 to 144.0 kDa. In conclusion, postbiotics of C. militaris mycelium significantly promoted anti-inflammatory activity, suggesting that neutral polysaccharides including Glc and Man contribute to the anti-inflammation in RAW 264.7 or HaCaT cells.

After liquid culture of Phellinus baumii (P. baumii) mycelium (LPBM) was prepared, LPBM was fractionated into A∼E fraction (A; hot-water extract of liquid culture including mycelia, B; crude polysaccharide of A, C; hot-water extract of mycelia, D; crude polysaccharide of C, and E; crude polysaccharide of culture broth) to evaluate for possibility as functional materials with immunostimulatory activity. In macrophage stimulatory activity, E fraction as postbiotics significantly increased secretion of NO and IL-12 from RAW 264.7 cells. Next, when the splenocytes of C3H/HeN mice were primary cultured, E fraction showed significantly mitogenic activity with enhancing mitogen-related cytokines (IFN-γ and TNF-α) production from splenocyte. E fraction also potently stimulated GM-CSF production from Peyer’s patch cells as well as Peyer’s patch-mediated bone marrow cell proliferation. In addition, the immunostimularoy E fraction contained neutral sugar (73.8%), uronic acid (10.6%), protein (7.8%), and polyphenol (7.5%), and mainly consisted of glucose (39.1%), galactose (21.7%), mannose (11.1%), galacturonic acid (9.9%), and arabinose (8.9%) as component sugars. In conclusion, it was demonstrated that postbiotics including exopolysaccharide fractionated from liquid culture of the P. baumii mycelium could enhanced immunostimulatory activity.

The development of ICT technology has created new channels for product sales and promotion, which not only make information accessible to customers as easy as possible, but also provide consumers with much more absolute and comparative information. Modern consumers are exposed so many shopping channels currently, especially mobile-based channels have grown significantly and have become the center of the market. It is true that mobile shopping has led the growth of overall online shopping with the recent development of mobile devices such as smartphones and related software. The importance of strengthening corporate competitiveness and mobile-based management strategies through on line channels continues to increase. At this point, this study attempted to investigate the influencing factors by focusing on the entire distribution channel and mobile shopping channels. As most of previous studies were focused on Internet shopping malls or specific channels, So the research on mobile channels can be judged to be timely and appropriate. Furthermore, it can be said that mobile shopping channels are now presenting empirical implications. In conclusion, it provides practical implications to examine the management strategy of mobile shopping channels from the perspective of consumer value.

In Korea, research on the introduction of dry storage facility is being conducted as an alternative to saturation of temporary storage facilities for spent nuclear fuel. The introduction of dry storage facilities requires a radiological impact assessment on the workers of the facility, and for this, an appropriate exposure scenario must be derived through work procedure analysis. In this study, the procedure for storing spent nuclear fuel in dry storage facilities was analyzed based on the case of evaluating the radiological impact of workers in dry storage facilities abroad. We investigated cases of radiological impact assessment on workers at on-site dry storage facilities by PNNL, Dominion, and P. F. Weck. PNNL and Dominion analyzed the storage work procedure of the VSC (Vertical Storage Cask) method using CASTOR V/21, TN-32, respectively, and conducted a radiological impact assessment. P. F. Weck analyzed the storage work procedure of various spent nuclear fuel casks for VSC and HSM (Horizontal Storage Module), conducted a radiological impact assessment. As a result of comparing the procedure for storing spent nuclear fuel by case, it was found that the storage procedure was determined by the storage method and the cask type. In the case of VSC method, canister-type casks and basket-type casks are used, and the storage procedure are partially different according to each. Canister-type cask requires repackaging from transfer overpack to storage overpack, but basket-type cask doesn’t require that procedure. In the case of the HSM method, only the canister type cask was found to be used. However, the storage procedure was different depending on the type of HSM system. Depending on the type of HSM system, the necessity of cask for on-site transport was different. In this study, we investigated and analyzed the work procedure according to the storage method of dry storage facilities abroad. It was found that the dry storage procedure of spent nuclear fuel different according to the storage method and type of cask. The results of this study can be used as basic when deriving the exposure scenario for spent nuclear fuel dry storage workers suitable for the domestic situation.

WAIS in South Korea and WEU Inc. in Philadelphia hosting the 22nd World Peace Island Forum: Remembering Jeju King Cherry Trees Bio-diplomacy (1943) in Washington D.C. and the first Korean Congress Democracy (1919) in Philadelphia which organized by the Korean Provisional Government from March 22 to 24, 2022. We want to propose cultural historic events which connect American and Korean society, such as the Trip to Faith and Liberty Hall that relate to the integration processes of Korean and American Democracy. Dean Max Friedman of American University calls the Jeju King cherry trees cultural event bio-diplomacy among world citizens. In addition, the Korean embassy evaluated the cherry tree event as a new kind of bio-diplomacy approach which paves the way for understanding different cultures in different countries. The aim of this paper is to share present contexts and meanings about both the first Korean Congress Democracy (1919) and Bio-diplomacy (1943). We had also the 2022 GAN Korea Jeju to Philadelphia Webinar Conference: Diversity as a New Diversity for Global Ageing Network in New Normal: Jeju Village Healing, PASSi Asian Culture, Japanese Indigenous Peace Culture, and Busan Smart Health Care approach.

Maca roots (Lepidium meyenii) are an important medicinal herb that have long been used by the Andes-indigenous peoples and South Americans. In Korea, recently, it has attracted attention as a health food material because of nutritional values and physiological activities. The purpose of this study was to investigate the industrial applicability of maca (red and golden varieties; R&G) as immunostimulating materials. In the macrophage stimulating assay using RAW 264.7 cells at 125~500 μg/mL of non-cytotoxicity doses, G-HW showed the most potent production of TNF-α, IL-6 and nitric oxide compared to red maca or the other extracts. The general component analysis results showed that all extracts comprised more than 90% neutral sugars with small amounts of uronic acid and protein. Meanwhile, component sugar analysis showed the difference in the content of uronic acids of cold- and hot-water extract. Additionally, the further fractionation of G-HW into crude polysaccharide (G-CP) greatly enhanced the macrophage stimulating activity, and G-CP contained macromolecules over 144 kDa, comprised mainly of glucose and galacturonic acid (51.0 and 34.9%). In conclusion, crude polysaccharide from maca showed industrial applicability as immunostimulating material, and especially golden maca showed higher macrophage stimulating activity than red maca.

Patient-controlled sedation systems, in which the patient has control of sedative administration, have been shown to be effective and safe for patients undergoing minor procedures. Safety depends on the adequacy of the step-wise increase in dose of the sedative, the lockout time and patient’s ability to adjust the effective activation of the handset. While there is no patient-controlled sedation (PCS) system available domestically, we have developed a new purpose-built PCS pump, and determined its degree of precision using a microweight measuring scale. The PCS system was designed to be applied to most intravenous sedatives and work through a newly developed operating software algorithm that titrates the doses and lockout times. Our system titrates the doses through software modification, and for experimental purposes, the number of steps for handset activation by the patient was set to four, and the lockout time was set to 30 s. The degree of precision of the PCS system was tested using an electronic weighing scale. The comparison of the amount infused via the PCS system with weight on the scale showed nearly same patterns at the four infusion stages, and the difference was minimal (3% on average at each infusion step). We designed and manufactured a pilot button-type PCS pump capable of use by the patient for optimal sedation, and confirmed the precise working mechanism of the pump, thereby reducing the margin of error for infusion accuracy to 3% or less on average

Culturally, it is wonderful that they try to integrated their ordinary life on the earth into heavenly spiritual life through their funeral rituals and song so called Yeong-Jang-Sori as same context as in the Pacific. During life, they eat traditional bread ( Bing-Teok) and drink traditional liquor (O-Me-Gi Ssol) and wear persimmon-dyeing Gal-ot healthily and they meet each other in the heaven eternally through happy dying. We are evidently sensitive to the unique cultural heritage of the island. UNESCO’s mission is the promotion of peace amongst peoples and its cultural heritage is also dedicated to working with indigenous peoples’ on their eco-friendlly knowledge of a sustainable planet. As Jeju Island is inscribed in part as both a World Heritage Site and a UNESCO Biosphere, it is important to give due consideration to the natural and cultural heritage of the island, as seen and experienced by the islanders. As such, if there is something useful we can discuss, for example the recognition of the special relationship between Jeju islanders and sacred natural sites on the island.

Maritime monitoring requirements have been beyond human operators capabilities due to the broadness of the coverage area and the variety of monitoring activities, e.g. illegal migration, or security threats by foreign warships. Abnormal vessel movement can be defined as an unreasonable movement deviation from the usual trajectory, speed, or other traffic parameters. Detection of the abnormal vessel movement requires the operators not only to pay short-term attention but also to have long-term trajectory trace ability. Recent advances in deep learning have shown the potential of deep learning techniques to discover hidden and more complex relations that often lie in low dimensional latent spaces. In this paper, we propose a deep autoencoder-based clustering model for automatic detection of vessel movement anomaly to assist monitoring operators to take actions on the vessel for more investigation. We first generate gridded trajectory images by mapping the raw vessel trajectories into two dimensional matrix. Based on the gridded image input, we test the proposed model along with the other deep autoencoder-based models for the abnormal trajectory data generated through rotation and speed variation from normal trajectories. We show that the proposed model improves detection accuracy for the generated abnormal trajectories compared to the other models.
