A casualty-estimation framework has been proposed that incorporates building-scale, time-varying occupancy data (considering factors such as size, use, and time of day) into earthquake loss modeling. Information from Seumter building records is combined with KOSIS population data, and HAZUS modules are used to estimate both the baseline population and dynamic occupancy at the building level. Case studies have shown a close alignment with observed data, with no significant model flaws, indicating the framework’s operational readiness. This approach moves beyond broad administrative totals to provide micro-spatial resolution suitable for Korea’s rapid seismic attenuation and localized damage patterns. It enables accurate, time-sensitive casualty estimates. The framework is designed to be scalable to include additional data sources, such as mobility, transportation, and activity patterns. It supports effective evacuation and shelter planning, surge capacity management, and prioritization of retrofitting, leading to more efficient resource allocation. Furthermore, the framework provides a consistent method to integrate future data streams and quantify uncertainty without disrupting the core workflow.

2000년 유럽경관협약이 채택되면서 경관을 일상공간의 공공자산이자 인권적 사안으로 확장하였으 나 우리나라에서 ‘경관에 대한 권리’ 개념은 학계 담론으로 정립되지 못했다. 이에 본 연구는 한국 법원의 경관 관련 판례를 통해 국내에서 경관에 대한 권리가 어떻게 현실화하고 있는지와 관련 법적 기제와 한계를 분석하는 것을 목적으로 한다. 본 연구는 대한민국 헌법재판소 결정문 18건과 대법원 판례 57건을 ‘경관’을 키워드로 수집·선정하고, 경관보호·비보호 판례로 분류하였다. 권리주체·의무 주체·권리근거·권리내용·사건행위·사건대상지 등을 분석 항목으로 설정하여 사례별 쟁점 양상을 정 량·정성적으로 파악하고, 셍키 다이어그램으로 시각화하였다. 분석 결과 경관보호 판례(57건)는 주 로 토지소유자 등 개인이 산림·보전지역 등 규제구역에서 재산권·점유권 침해를 다투며, 행정청의 재량권 남용을 근거로 보호 처분 취소를 구한 사례였다. 반면 경관불보호 판례(13건)는 지역공동체 가 환경권을 사법적 권리로 청구했으나, 법원은 ‘사회통념상 수인 한도’를 이유로 사전 예방·사후 구제를 제한하였다. 이로써 한국 법원은 (1) 조닝제도에 기초한 지형적 경관권 경계를 설정하고, (2) 경관을 공익과 사익 간 대립으로 이해하며, (3) 공동체 권리주체성을 제한하고, (4) 경관침해 판단 기준으로 사회통념적 수인한도를 활용함으로써 ‘경관에 대한 권리’를 전면적으로 인정하지 않았다. 따라서 ‘경관에 대한 권리’ 개념을 실질화하기 위해서는 경관법·국토법 등 관계 법령에 권리주체·행 사방식·구제수단을 구체화하고, 법원의 경관권 인정 태도 변화를 유도할 제도적 보완이 필요하다.

The purpose of this study is to assess the current status of technology development and evaluate future potential by analyzing patent trends in Korea’s fisheries sector. To this end, we examined patent application and registration trends over a 20-year period (2002-2021) within the fisheries domain across the Intellectual Property 5 (IP5) countries (Korea, China, Japan, the United States, and Europe), using data from the Korean Multifunctional Patent Search System (KOMPASS). Based on this analysis, we discussed the strategic direction and marketability of technology development in Korea. Patent applications and registrations in Korea’s fisheries sector have steadily increased over the past 20 years, placing Korea the second among the IP5 countries. Analysis of priority examination data indicates a continuous rise in new technology development, particularly in the aquaculture and seafood. However, multiple-International Patent Classification (IPC) applications are heavily concentrated among a small number of institutions, highlighting the need to broaden the applicant base to encourage more widespread technological innovation. Korea’s fisheries technology sector is currently in the growth stage with sustained development expected in aquaculture and seafood-related technologies. Although Korea entered the IP5 landscape relatively late, it possesses strong competitiveness and considerable development potential positioning it to assume a leading role in the global technology market.

Understanding long-term changes in fisheries resources is essential for sustainable ecosystem-based management. This study assessed the quantitative and qualitative changes in Korean coastal fisheries from 1971 to 2024 using an ecological group-based approach. Catch data for approximately 130 species were grouped into 21 ecological groups, and the CMSY model was applied to estimate historical biomass and stock status. Future catch and biomass were projected to 2050 under a conservative scenario assuming reduced resilience. Biodiversity and ecosystem structure were evaluated using mean trophic level (MTL), diversity index (DI), and pelagic/demersal fish ratio (P/D) based on both catch and biomass. Historical total catch and biomass declined substantially while future projections suggest stabilization or modest recovery. The proportion of demersal fish decreased over time and is expected to remain low. MTL showed a gradual downward trend in both catch- and biomass-based indicators. DI showed similar fluctuating trends across both datasets. Although P/D values differed in magnitude, both indicators exhibited a consistent pattern of increase followed by decline, indicating ecosystem structural shifts.

This study investigated seasonal variations in phytoplankton community composition and physicochemical water quality across 90 lakes in South Korea surveyed 2022 to 2024, and examined their relationships with environmental factors. Over the course of four seasons, a total of 952 phytoplankton taxa were identified, with Bacillariophyta (diatoms) and Chlorophyta (green algae) accounting for 64.2% of the total species richness. Diatom species such as Aulacoseira granulata, Fragilaria crotonensis, and Cyclotella meneghiniana were frequently observed regardless of season. In terms of cell density, Cyanophyta were dominant, comprising 85.1% on average, with particularly high summer densities driven by blooms of Microcystis aeruginosa and Aphanizomenon sp. In contrast, diatoms accounted for the highest relative abundance in winter (54.1%). Canonical correspondence analysis (CCA) revealed that Cyanophyta and Chlorophyta were positively correlated with water temperature, TP, COD, and Chl-a, whereas Bacillariophyta and Cryptophyta showed negative correlations with these variables. These results indicate that phytoplankton communities in Korean lakes are highly responsive to variations in temperature and nutrient concentrations, and that summer rainfall-driven nutrient inflow plays a critical role in triggering cyanobacterial blooms. This study provides a scientific basis for understanding seasonal ecosystem dynamics in Korean lakes and offers foundational data for eutrophication management and the development of biological water quality assessment indices.

본 연구는 상록활엽수림이 존재하는 도서지역 중 제주도, 울릉도, 흑산도, 홍도, 완도 총 5개 도서를 대상으로 군집유 형을 분류하고 분류된 군집별 층위 구조와 환경 특성을 구명하고자 수행되었다. 야외조사는 2020년부터 2024년까지 식물사회학적 방법으로 총 143개의 조사구에서 식생조사를 진행하였으며, 조사된 자료는 클러스터 분석을 통해 군집유 형을 분류하였다. 그 결과, 후박나무군집, 종가시나무군집, 구실잣밤나무군집, 붉가시나무군집 총 4개의 군집유형으로 분류되었다. 분류된 군집의 중요치를 통한 층위 구조를 볼 때 모든 군집에서 현재의 구조가 당분간 유지될 것으로 판단되었으나, 아교목층과 관목층에서 후박나무, 까마귀쪽나무, 동백나무 등의 수종이 층위 경쟁을 하고 있어 상록활엽 수 임분의 천이과정을 이해하기 위해서는 경쟁 수종들의 장기 관찰이 필요할 것으로 판단되었다. 종다양도는 다른 군집에 비해 종가시나무군집에서 높게 나타났는데, 이는 종가시나무군집의 입지가 계곡성이기에 나타난 결과로 판단되 었다. 수관 계층에서는 종가시나무군집을 제외한 3개의 군집의 교목층 최저 수고가 낮게 나타났는데 이는 홍도, 흑산도 에 위치한 조사지의 입지가 해안가 급경사지에 위치하여 나타난 결과로 판단되었으며, 종가시나무군집은 수관 계층고 특징으로 인해 상대적으로 광 투과율이 높아 하층의 종다양도가 높게 나타난 것으로 판단되었다. 군집별로 해발고도, 방위, 위도 3가지의 환경인자가 통계적으로 유의미한 차이가 있었는데, 난온대지역의 상록활엽수림을 복원 또는 신규조 림 시에 해발고도, 방위, 위도를 고려하여 수종을 선택할 필요가 있다고 판단되었다.

Damage to masonry walls can occur for various factors. It is often believed that heavy rains and increased rainfall cause soil and sand to flow into the stone masonry walls, leading to this damage. However, no research has definitively proven or analyzed this causal relationship.This study aims to evaluate the causes of damage to masonry walls due to severe rainfall and to propose preventive strategies to mitigate future risks. The assessment found that, as a form of cultural heritage, the stone masonry walls did not exhibit any structural or material issues that could compromise their stability. However, concerns were raised about potential problems arising from hydraulic pressure due to rising groundwater levels. Calculations and computer simulations confirmed that the risk of collapse increases with higher groundwater levels. Therefore, it is essential to carry out repairs and reinforcements to prevent a recurrence of this situation.

The pioneering effort of Korea's distant water fisheries can be traced back to 1957 when Jinam-ho, affiliated with Jedong Industry Co., embarked on a tuna longline sea trial in the Indian Ocean. The success of this sea trial holds significant importance as it laid the groundwork for Korea to venture into the Pacific tuna fishing grounds, which were predominantly dominated by the United States and Japan at that time. The Korean distant water fisheries experienced remarkable growth in a short period, from the inception period in the 1950s, the pioneering period in the 1960s, the growth period in the 1970s, and the development period in the 1980s. However, a series of changes in the international situation, including the global oil crises of 1973 and 1978, the declaration of 200-nautical-mile zones by coastal states in 1977, and the adoption of the United Nations Convention on the Law of the Sea (UNCLOS) in 1982 and the United Nations Fish Stocks Agreement (UNFSA) in 1995, made a significant transformation in the Korean distant water fisheries inevitable. In particular, UNFSA grants the authority to conserve and manage fisheries resources to the Regional Fisheries Management Organizations (RFMOs), and stipulates that coastal states and fishing nations cooperate with each other through RFMOs. In order to reclaim the once vast fishing grounds and secure maritime territories, it is imperative to have both the keen attention of the fishing industries and the strategic support of the government. In addition, to secure competitiveness in the international community, we should faithfully fulfill the role as a responsible fishing nation and contribute to RFMOs by strengthening scientific activities.

Key predictors included flexible leave policies, social insurance, remote work options, and job security. The findings highlight the importance of supportive organizational policies in retaining female employees. Future research should explore longitudinal impacts and additional variables like organizational culture.

느티나무(Zelkova) 속은 전세계적으로 대부분 멸종위기종으로 발표되고 있어 그 보전가치가 높으며, 우리나라 자생 종인 느티나무(Zelkova serrata)는 준위협종(Near Threatened, NT)으로 발표되고 있다. 따라서, 본 연구는 2018년부터 2023년까지 총 125개소의 느티나무림을 대상으로 식생유형과 층위구조를 파악함으로써 느티나무 자생지 보전을 위한 생태적 천이경향을 구명하고자 수행되었다. 종조성에 따른 유형분류 결과, 총 4개의 식생단위와 7개의 종군유형으로 분류되었다. 느티나무군락군은 비목나무군락(소나무군, 개서어나무군), 참식나무군락으로 분류되었다. 각 식생단위의 층위별 중요치를 분석하여 느티나무림의 천이경향을 분석해본 결과, 느티나무림은 ◯1 느티나무 우점군락으로 당분간 유지되는 유형, ◯2 고로쇠나무 중심 군락으로의 천이가 예상되는 유형, ◯3 참식나무와 소사나무 혼합군락으로의 천이가 예상되는 유형의 총 3가지 천이유형으로 나타났다. 따라서, 느티나무의 체계적 보전을 위해서는 임분의 수직적 구조를 고려한 천이유형별 관리방안 마련이 필요할 것으로 판단된다.

This study was conducted to analyze New Zealand’s beekeeping industry and Manuka honey grading system to suggest characteristics and development plans for Korea’s honey grading system. Manuka honey in New Zealand is harvested from the Manuka tree (Leptospermum scoparium). It is known for its various bioactive properties, including antimicrobial activity and antioxidants. Since 2017, the New Zealand government has been implementing national certification and grading for all exported Manuka honey. For this purpose, compositions of Manuka honey across New Zealand have been investigated and four chemical indicators and one biological indicator have been established. Currently, Korea has been fully implementing a honey grading system since September 2023, which divides honey (acacia honey, chestnut honey, and miscellaneous honey) into 1+ grade, 1 grade, and 2 grade according to Enforcement Rules of the Livestock Act. The following seven indicators are used: carbon isotope consumption, moisture content, sugar ratio, hydroxytmethylfurfural, flavor, chromaticity, and defects, similar to Codex standards or European standards. However, details are modified to suit Korean conditions. To make the Korean honey grading system more stable, it is necessary to develop and introduce different indicators for honey functionality and honey grading system maturity. In addition, it is necessary to expand the participation of farmers in the honey grading system, secure consumer trust in the honey grading system, and continue to promote it.

The aim of this study was to evaluate the carbon storage capacity of broad-leaf forests in Republic of Korea through the analysis of studies related to carbon storage and carbon uptake, and to analyse the relationship between climatic factors affecting carbon storage capacity. We analysed the results of each previous study by summarising the research results of 55 previous studies collected through search, and organised the study area information and climate factors (elevation, average annual temperature, annual precipitation, etc.). And the carbon storage and net primary production of the above and below-ground and the whole plant were evaluated and the correlation with the climatic factors was statistically analysed. The analysis showed that the carbon storage of broad-leaved forests was positively correlated with altitude and negatively correlated with precipitation. These results mean that carbon accumulation in plants is more effective at higher altitudes with lower temperatures, and that broad-leaf forests are able to adapt and perform carbon storage functions in areas with low precipitation. Carbon uptake was negatively correlated with altitude and positively correlated with temperature. This means that the carbon absorption capacity of broad-leaved forests is greatly affected by temperature, and that the carbon absorption potential is greater in lowlands. Therefore, policies should be actively established to increase and preserve the carbon storage capacity of forests by considering the characteristics of the ecosystem functions of broadleaf forests and climate factors. The results of this study are expected to contribute to the understanding of the carbon cycle of broad-leaved forests and to the development of management measures, and to provide scientific data for carbon neutrality.

이 연구의 목적은 우리나라 자립준비청년을 대상으로 한 정책의 현황 과 문제점을 파악하고 개선 방안을 논의하는 것이다. 자립준비청년은 원 가정에서 분리되어 국가의 보호를 받다가 성인이 되어 보호가 종료된 뒤 자립을 준비하고 실행하는 청년들을 말하며, 이들은 경제적, 교육적, 심 리적, 사회적으로 다양한 문제를 겪고 있다. 이들을 지원하기 위해 보건 복지부 중심의 자립지원정책이 2019년부터 본격화되었으나, 지금까지의 연구와 논의들은 자립지원정책을 통합적으로 살펴보지 못한 한계가 있 다. 본 연구는 정책자료와 학술자료를 바탕으로 자립지원정책의 현황과 문제를 종합적으로 분석했다. 분석 결과, 자립지원정책은 부처 간 지원 내용에서 차이가 있었고, 이는 자립준비청년 간 자립역량과 자립수준의 격차로 이어질 가능성을 확인했다. 특히, 현 정책은 청년이 된 이후의 지 원에 초점이 맞추어져 있고 청소년기부터 개인별 자립역량을 체계적으로 강화할 수 있는 로드맵이 부재했다. 이에 본 연구는 자립준비청년 지원 정책의 개선 방안으로, 자립지원 전달체계의 통합과 자립지원 방식의 다 각화를 제안하였다.

This study aims to establish the concept of fish welfare and develop guidelines for its implementation in South Korean aquaculture. As global awareness of animal welfare grows, scientific evidence shows that fish are sentient beings capable of experiencing pain and that stress has led to increased demand for welfare standards in aquaculture. International organizations like WOAH and the EU have set welfare standards for farmed fish, emphasizing their importance for health, productivity, and food safety. However, in South Korea, fish welfare is still an emerging concept with limited research. This study systematically defines fish welfare, assesses its feasibility in domestic aquaculture, and proposes guidelines tailored to local conditions. The findings highlight the need for gradual implementation, considering the unique biological and environmental factors in fish farming.
