이 연구는 한국과 호주 간 양자 협력 의제 중 자원 안보와 밀접한 관 련이 있는 탄소중립 기술 개발, 핵심 광물 공급망 그리고 농업 협력을 중심으로 살펴본다. 탄소중립 기술과 핵심 광물 공급망 같은 경우 2021 년 양국의 포괄적 동반자 관계 수립 이후 급격하게 협력이 시작되었고 정부와 주요 기업들이 적극적으로 참여하였다. 이에 반해 농업 협력은 2014년 양국의 자유 무역 협정 이후 협력위원회가 단 한 차례밖에 열리 지 않았다. 농업 협력은 향후 식량안보와 밀접한 관련이 있기에 협력이 순조롭게 진행될 수 있도록 노력을 기울일 필요가 있다. 향후 자원확보 와 공급망 구축이 그 무엇보다 중요한 시기에 양국의 상황을 면밀하게 관찰하고 부족한 부분의 협력을 적극적으로 모색하는 노력이 매우 중요 하다.

The World Vegetable Center (WorldVeg) maintains the world’s largest public vegetable germplasm collection. The Genebank contains over 65,000 accessions and consists of more than 130 genera and 330 species. It includes around 12,000 accessions of indigenous vegetables. The WorldVeg Korea Office (WKO) has been conducting regional adaptability evaluations in the fields of the National Institute of Horticultural and Herbal Science (NIHHS), with a focus on major solanaceous vegetable crops such as tomato, chili, and bell pepper. As climate change significantly affects vegetable crop productivity, the development of high-performing cultivars, tolerant to various abiotic and biotic stresses with enriched nutrients inside, is essential to enhance agricultural sustainability and human health. In this regard, the evaluation of growth and horticultural characteristics of pepper and tomato accessions from the WorldVeg will help contribute to the generation of new and improved cultivars, to address global challenges that affect food security, sustainability, and adaptation to climate change. Here, we summarize our activities and the results of the regional adaptability evaluation using the WorldVeg accessions of pepper and tomato germplasms.

This study aims to establish a development strategy for higher education in Indonesia’s marine and fisheries sector and to present a direction for international development cooperation through evaluating policies and current problems related to higher education in marine and fisheries sector. To achieve the goals of human resources development in marine and fisheries sector, Indonesian government needs to secure non-salary expenditures to strengthen support for areas directly related to the effects of education, such as improving educational facilities, expanding scholarships, and so on. Education institution needs to develop effective teaching methods and systematic practice-based curriculum that reflects the needs of the local fishermen community and fisheries industry. In addition, it is necessary to support the supply of manpower throughout the fisheries industry. Fisheries industry needs to stop relying on the government or education institutions to secure excellent human resources and actively participate and cooperate in the education field so that excellent human resources can flow into the industry. Based on this strategy, international development cooperation for human resources development in Indonesia’s marine and fisheries sector should focus on qualitative rather than quantitative expansion of higher education institutions.

With a rapid expansion in electric vehicles, a huge amount of the spent Li-ion batteries (LIBs) could be discharged in near future. And thus, the proper handling of the spent LIBs is essential to sustainable development in the industry of electrical vehicles. Among various approaches such as pyrometallurgy, hydrometallurgy, and direct recycling, the hydrometallurgical manner has gained interest in recycling the spent LIBs due to its high effectiveness in recycling raw materials (e.g., lithium, nickel, cobalt, and manganese). However, the hydrometallurgical process not only requires the use of large amounts of acids and water resources but also produces toxic gases and wastewater leading to environmental and economic problems, considering potential economic and environmental problems. Thus, this review aims to provide an overview of conventional and state-of-the-art hydrometallurgical processes to recover valuable metals from spent LIBs. First, we briefly introduce the basic principle and materials of LIBs. Then, we briefly introduce the operations and pros-and cons- of hydrometallurgical processes. Finally, this review proposes future research directions in hydrometallurgy, and its potential opportunities in the fundamental and practical challenges regarding its deployment going forward.

The objectives of this study were to analyze the fish community structures and distribution characteristics of fisheries resources in the Osip Stream and Wangpi Stream, fishery resources protection areas. For the study, we conducted fish samplings four times in the two streams from April to October 2019. In Osip Stream and Wangpi Stream, we sampled 31 species and 29 species and the dominant species were Zacco platypus (28.6%) and Squalidus multimaculatus (41.7%), respectively. According to the life type of fish species, primary freshwater species were collected 18 species (58.1%) and 21 species (72.4%), and migration fishes were sampled 4 species (12.9%) and 6 species (20.7%) in Osip Stream and Wangpi Stream, respectively. Fisheries resources species showed high relative abundance in June, and the fish biomass was highest in October. As a results of comparing the previous studies with this study, both rivers showed high biodiversity and were found to maintain stable populations of fishes. According to analysis of tolerance guilds, the proportion of tolerant species, based on the number of individuals, was composed of 14.4% and 1.1% in Osip Stream and Wangpi Stream, respectively. This very low ratio of tolerant species confirmed that both streams have very good physiochemical environment conditions. From the above results, it was judged that the fishery resource protection areas of Osip Stream and Wangpi Stream have high ecological function and preservation value. For sustainable use and management of fishery resource protection areas of Osip Stream and Wangpi Stream, it is suggested that biological disturbance management, fish discharge projects considering environmental capacity, efforts to improve the habitat environment, and establishing a fishery resource protection areas management system were necessary as considerations.

Recently, local studies looking at the 'local(region) as a whole' are gradually increasing. The study of local architectural history is important in that it provides specific information that encompasses the local and the entire and clues to three-dimensionalize the time and space in the local. To infer the 'presentness' of each era, reliable data in various fields are needed. Recently, as many databases (DB) and archives, from the 'National Archives of Korea' to other local archives, have been established and publicized, research resources in the local are growing rapidly in quantity and quality. Nevertheless, it is difficult to comprehensively check the data necessary to study the local architectural history(local architectural history research resources). Against this background, this study confirmed the trend of changes in the archive construction environment and the status and problems of local architectural history research resources in places that currently disclose local history research resources among generalized web-archives. Next, the relationship between the actual research on local architectural history was confirmed through the analysis of existing studies and the data used for Jeju. As a result, local studies, local archives, and local architectural history research agree with recent changes in local research trends, and the degree of archival construction has reached the same level as the available research resources except core data in local architectural history research. However, there is a problem that the density of information that can be used is low because the local architectural history research resources that can be obtained are fragmented because there are no archives and construction entities specialized in local architecture. As each archive has entered the stabilization and upgrading stage, the construction of new archives needs to be reconsidered, but it is time to find a detailed way to link related information quickly and accurately, such as private records, to reduce the gap in information needed in terms of research on local architecture and architecture history.

Due to the rapid growth of electrical vehicle and portable electronics markets, huge amount of the rare earth elements (REEs) and lithium have been required for the manufacturers globally. Moreover, after life time of the battery pass, the waste batteries containing valuable metal resources should be recycled due to competitions between the countries who manufacturing the batteries. Therefore, the REEs and lithium recoveries from the e-waste and wastewaters become issue recently. However, the commercialized technology for the valuable metal recovery is limited. In this study, the uses of the REEs and other valuable metal resources such as lithium, uranium, and gold and there recoverying methods according to the different water conditions were investigated and summarized. Moreover, the possible expectations and suggestions for the future application of the valuable resource recovery were conducted as a review.

Public complaints arising from centralized animal manure treatment plants are increasing due to the odors produced during animal manure treatment. Various physico chemical and biological methods are used to mitigate such odors. Still, many problems exist, such as a lack of fundamental data on odor generation characteristics and design standards for odor mitigation facilities. Therefore, this study evaluated the characteristics of NH3 and H2S gas produced from a centralized animal manure treatment plant. The centralized animal manure treatment plant selected in this study has a treatment capacity of 150 tons (animal manure and food waste) per day. The composting matrix was mechanically turned from 9:00 am to 6:00 pm on weekdays and not turned all day on weekends. The NH3 concentrations measured during the day on weekdays (96.4 ± 7.8 ppmv) were about 14% higher than on weekends (84.9 ± 15.9 ppmv). During the week, the ammonia concentration during the day was about 15% higher than at night, but there was no difference between day and night on weekends. The hydrogen sulfide concentration during the day (4,729 ± 3,687 ppbv) on a weekday was about 4.7 times higher than at night (1,007 ± 466 ppbv). The results of this study provide valuable information that is necessary for the operation of odor mitigation facilities. It is expected that the results will contribute to establishing an operational strategy that can reduce the energy required to collect exhaust gas.

1990년대 이후 한국경제에서 경제 서비스화와 학력별 임금격차 확대 현상이 나타났다. 이런 상황에 서 학력별 노동수요의 결정요인분석을 위해 먼저 인적자본론을 바탕으로 노동을 고학력노동과 저학력노 동으로 분리하였다. 생산함수는 콥-다글라스 함수로 가정하고 생산요소는 물적자본(K), 저학력노동( ) 과 고학력노동( )으로 하였다. 이것을 바탕으로 외생변수로 기술진보(t), 산출량(Q)과 세계화()를 상 정한 학력별 노동수요함수를 도출하였다. 이것을 바탕으로 로그선형회귀모형을 설정하고 한국의 주요 3 개 산업(제조업, 건설업, 금융업)의 학력별 노동수요에 영향을 미치는 요인을 비교분석하였다. 주요 3개 산업의 학력별 노동수요 결정요인을 비교분석한 결과 다음과 같은 공통점과 차이점을 발견하였다. 첫째, 학력별 노동수요는 생산요소 상대가격보다는 생산량, 기술변화와 세계화 등 외생적 요인의 영향을 받아 고학력노동수요 중심의 노동시장구조로 변화하고 있다. 특히 학력별 노동의 상대임금이 학 력별 노동수요에 유의미한 영향이 없을 정도로 학력별 노동시장은 분절되어 있다. 둘째, 생산량 증가(감 소)는 건설업의 고학력노동과 저학력노동수요에 가장 큰 고용증가(구축)효과를 가져왔다. 따라서 건설업 이 경기변동에 가장 민감한 산업임을 알 수 있다. 기술진보는 제조업의 저학력노동에 가장 큰 고용구축효 과를, 금융업의 고학력노동에 고용증가효과를 가져왔다. 셋째, 세계화는 제조업에서 저학력노동과 고학력 노동의 고용증가효과를, 금융업에서는 고학력노동의 고용증가효과를 가져왔지만 건설업에서는 학력별 노동수요에 유의미한 영향을 미치지 못했다. 이런 연구 결과를 바탕으로 한국 주요 산업의 고용에 대해 다음과 같은 시사점을 제공한다. 첫째, 요소 상대가격 변화를 통한 정부정책이나 기업전략은 학력별 노동수요에 대한 영향이 미미하여 제한적일 수밖 에 없다. 둘째, 기술진보로 인해 제조업에서는 저학력노동의 고용구축효과에 따른 기업의 노무관리가 필 요하다. 반면 금융업에서는 기술진보와 세계화로 인한 고학력노동의 고용증가효과에 대비하기 위해 기업 차원에서는 기존노동의 교육과 훈련 프로그램이, 정부차원에서는 인재양성정책이 필요하다. 셋째, 건설업 은 경기에 민감하기 때문에 경기호불황에 대비하기 위한 기업의 고용안정전략이 필요하다.
