At a time when it is urgent to establish a management system for landscape quality assessment of offshore wind farms in Korea, we analyzed foreign cases to draw implications for improving the landscape quality assessment of offshore wind farms in Korea and to explore the direction of efficient landscape assessment. The main contents derived from the analysis of overseas cases and systems are as follows. First, offshore wind farms are large-scale projects, and it is necessary to consider the landscape from the pre-planning stage, as in overseas cases. Second, the evaluation items for marine landscape quality should be expanded and systematized. Third, a flexible evaluation system that can consider new landscape impacts is required. In order to identify the landscape impacts of offshore wind farm projects, we refer to the landscape assessment items and procedures derived from overseas cases, but reflect them appropriately to the domestic maritime conditions, and specifically introduce a plan to minimize the landscape impacts that may occur during offshore wind farm projects to contribute to the sustainable use of offshore wind power.

Indigenous fermented foods have played a vital role in human history, and continue to offer a multitude of diverse sensory characteristics. According to earthenware relic, the fermented fisheries products might be consumed in Korean peninsula from Paleolithic period. The traditional Korean fermented fish products are classified into four groups; Jeot-gal (sik-hae), Aek-jeot, Seasoned Jeot-gal, and Seasoned Aek-jeot. Jeot-gal is a fermented fishery with salt. Aek-jeot is a liquid part of Jeot-gal. Sik-hae is manufactured by fementing fishery with salt, cereal, malt powder, etc. Seasoned Jeot-gal is a salt-seasoned fish with red pepper powder, garlic, onion, etc. Seasoned Aek-jeot is a seasoned product by adding "salt-water" or "condiment" to Aek-jeot. The fermented fisheries industry has traditionally been succeeded mainly in a cottage scale to the middle of 20th century. Thereafter, together with the development of pelagic fishery, the fermented fisheries industry also developed constantly to an enterprise size.

This study evaluated the antioxidizing and antiproliferative effects of Angelica japonica extract and its solvent-partitioned fractions. A dried sample of the halophyte A. japonica was extracted twice using methylene chloride (CH₂Cl₂) and extracted twice again using methanol (MeOH). The combined crude extracts were then fractionated by solvent polarity into distilled water (water), n-butanol (n-BuOH), 85% aqueous methanol (85% aq.MeOH), and n-hexane fractions. The antioxidant activities of the crude extracts and their solvent-partitioned fractions were assessed according to their DPPH radical and peroxynitrite scavenging abilities, formation of intracellular reactive oxygen species (ROS), DNA oxidation, NO production, and ferric reducing antioxidant power (FRAP). The crude extract showed significant antioxidant activity in the overall antioxidizing bioassay systems. Among solvent-partitioned fractions, good antioxidant activities were observed in n-BuOH and 85% aq.MeOH fractions and significantly correlated with the polyphenol and flavonoid contents of the samples. Furthermore, all samples tested, including the crude extract, not only showed cytotoxic effects against human cancer cells (AGS, HT-29, MCF-7, and HT-1080) but also prevented cell migration in a dose-dependent manner in the wound healing assay using HT 1080. Among the solvent-partitioned fractions, the 85% aq.MeOH fraction most effectively inhibited the invasion of HT-1080 cells. Therefore, these results suggest that A. japonica may be a potential antioxidizing and antiproliferative agent.

The purpose of this study is to examine the perception of early childhood teachers on ecological art activities oriented to education for sustainable development. The research results are as follows. First, Early childhood teachers recognized the visual art of natural media, the pursuit of community values, and the participation and communication of social members as educational significance of ecological art activities. And difficulties in practicing ecological art were recognized as lack of educational environment, lack of ecological art teaching materials and specific examples, and teachers' lack of understanding of ecological art. Also, they recognized that ecological art activities foster core competencies in art experience area, such as nature-friendly communication skills, eco-friendly sensibility, and creative convergence skills. Second, regarding ecological art activities and sustainable development education, early childhood teachers considered the difficulties in practice as lack of awareness about sustainable development, lack of play meia and materials, lack of educational policies and support, and insufficient teacher training programs. Also, regarding the SDGs that can be practiced in ecological art activities, teachers were found to be highly aware of 'grow affordable and clean energy', 'improve clean water and sanitation', 'provide quality education' in the order. In the contents of education for sustainable development that can be practiced in ecological art activities, teachers are given the order of 'climate change response', 'clean energy', 'water and sanitation', 'quality education', 'health and well-being' and 'marine ecosystem'. was highly recognized. If an ecological art activity program is developed, the rate of responding that it will be used is high, so it is considered that the development of an ESD-oriented ecological art activity program is urgent.

The halophyte Artemisia scoparia is an edible medicinal plant, with insecticidal, anti-inflammatory, anticholesterol, antipyretic, and antibacterial effects. The aim of this study was to assess the inhibitory effect of crude extract and solvent-partitioned fractions obtained from A. scoparia on MMP-2 and MMP-9 activity in phorbol-12-myristate-13-acetate (PMA)-stimulated human fibrosarcoma HT-1080 cells using four different activity tests: gelatin zymography, MMP enzyme-linked immunosorbent assay (ELISA), wound healing assay, reverse transcription-polymerase chain reaction (RT-PCR), and Western blot assay. A. scoparia samples were extracted twice with methylene chloride (MC) and twice with methanol (MeOH). After the MC and MeOH crude extracts were combined, the combined crude extracts showed a significant inhibitory effect against MMP-2 and MMP-9 enzymes. They were then fractionated into n-hexane, 85% (v/v) aqueous methanol (85% (v/v) aq.MeOH), n-butanol, and water according to solvent polarity. Among the four solvent-partitioned fractions, n-hexane and 85% (v/v) aq. MeOH fractions significantly inhibited MMP-2 and MMP-9 activity and cell mobility. In addition, the n-hexane and 85% (v/v) aq.MeOH fractions effectively inhibited MMP-2 and -9 activity in the gelatin zymography and MMP ELISA assay. In the wound healing assay, RT-PCR, and Western blot assay, all solvent-partitioned fractions, except the H₂O fraction, significantly suppressed cell migration, as well as the expression levels of MMP-2 and -9 mRNA and proteins.

This paper proposes a safety management method that extracts ETA (event tree analysis) based scenario and combines ICT technology to reduce serious disasters occurring workplace for shipbuilding and offshore plant. The statistics of Safety and Health Agency and (previous)Ministry of Public Safety and Security show that the most frequent accident among the serious disasters related to shipbuilding and offshore plant is falling. The main cause of accidents is absence of a safety belt and safety belt ring. To solve these problems, we create ETA based scenarios to derive results based on safety considerations. Based on these results, we propose a solution by applying ICT technology for accident prevention. Deriving ETA based scenarios and ICT technology, the proposed solutions include a system for detecting the wearing of safety belts and safety helmets, a system for detecting whether or not the safety belts are connected, and a hook system for measuring safety distances. These safety related systems can reduce the probability of death of workers. By preventing accidents using the proposed method, we can reduce serious disasters in shipbuilding and offshore plant and establish systematic safety management.

Suction buckets are feasible options for offshore foundations to support subsea structures in deep water, enabling suction-induced installation by pumps. Recently, hybrid suction bucket foundations that combine single or multiple suction buckets with a mat foundation have been considered. The foundations effectively increase the load capacity while reducing construction costs. However, there is still insufficient experimental validation of hybrid suction bucket foundations regarding their bearing capacity. Furthermore, research on the horizontal load capacity under low vertical and moment loads is inadequate. In this study, we investigate the feasibility of using a hybrid suction bucket foundation for subsea installations in clay. We considered two types of hybrid suction bucket foundations: a circular mat with a single suction bucket and a square mat with multiple buckets. Centrifuge tests were performed to understand the hybrid suction bucket foundation characteristics under horizontal loads and their corresponding bearing capacity. Particularly, we verified the effect of the mat foundation and bucket embedment depth on the horizontal bearing mechanism and capacities. Results confirmed that the hybrid suction bucket foundation outperforms the single suction bucket.
