Korea’s fisheries industry has long played a crucial role in national food security and economic development. However, fisheries resource depletion, marine environmental degradation, and climate change have heightened the need for effective fisheries resource management. This study examines overlapping and conflicting regulations within Korea’s fisheries resource management system and proposes science-based solutions to improve regulatory effectiveness. Through a comprehensive review of fisheries-related laws and policies, combined with case studies on minimum catch sizes, closed seasons, and total allowable catch (TAC), this study identifies multiple instances of regulatory overlap. These include inconsistencies in minimum catch size regulations across different laws and conflicts between TAC and other regulatory measures. Such overlaps reduce administrative efficiency, increase compliance costs for fishers, and weaken the effectiveness of fisheries resource management. To address these challenges, this study aims to analyze the current status of overlapping regulations in Korea’s fisheries resource management system and present scientific and rational solutions. Ultimately, the research seeks to enhance administrative efficiency, alleviate burdens on fishers and contribute to the establishment of a sustainable fisheries resource management framework.

This study quantitatively evaluated the real-world performance of an IoTbased, context-aware mobile air purification system. Additionally, this system is proposed as a practical alternative to conventional stationary purifiers, overcoming their spatial limitations. To analyze concentration variations, removal efficiency, and air cleaning ratio (ACR) for PM2.5, PM10, and HCHO, three scenarios were tested: S1 (natural ventilation), S2 (stationary purifier), and S3 (IoT-based mobile air purification system). The mobile system (S3) achieved a 1.6-fold higher removal efficiency for PM2.5 compared with the stationary purifier (S2) and reduced the ACR to below 0.4 within 30 minutes after high-concentration events. In contrast, stationary purifiers required approximately 333 minutes to reach background levels (17.11 μg/m3), revealing about a 10-fold difference in cleaning speed. Monte Carlo simulations confirmed the consistent superiority of S3 for both particulate and gaseous pollutants, with HCHO concentrations 36.7% lower (90th percentile) than under S2. According to the health risk assessment, the asthma hospitalization rate decreased by over 40%, the HQ for PM2.5 decreased from 1.1 (S1) to 0.64 (S3), and the ECR for HCHO was 0.62 times that of S2. These findings highlight that spatial responsiveness and mobility, along with filter capacity, are key determinants of air purification performance. In conclusion, the mobile air purifier effectively overcomes the structural constraints of stationary devices and establishes a new paradigm for realtime, adaptive indoor air quality management that helps safeguard occupant health.

This study aims to quantitatively and qualitatively evaluate the operational effects of an emergency-vehicle preemption (EVP) system implemented in Anyang City and to derive improvement directions based on both empirical performance outcomes and user-experienced insights. Specifically, this study integrates three complementary methodologies: (1) controlled field tests comparing pre- and post-EVP travel performance under consistent traffic and signal conditions, (2) a one-year operational evaluation using 204 actual dispatch cases collected from six 119 Safety Centers, and (3) a structured survey of frontline firefighters who directly utilized the EVP system during actual emergency responses. The field test results indicated that the average travel time reduced by approximately 44% while the average travel speed increased by approximately 79%, with paired t-test verification confirming that the observed improvements were statistically significant and attributable to the EVP system instead of to random variations. Similarly, the operational evaluation indicated that the actual travel time reduced by an average of 49% compared with navigation-estimated values, whereas the golden-time (5 min) arrival rates for both fire/rescue and medical dispatches exceeded the regional average, with consistent performance demonstrated even under varying travel distances and road complexities. The firefighter survey further reinforced these findings, with respondents reporting clear improvements in golden-time achievement, reduced anxiety toward potential safety risks, and enhanced perceived safety during emergency trials, as well as identified several practical limitations such as route mismatches, occasional system malfunctions, and difficulty in perceiving preemption activation—factors that suggest necessary technical and operational refinements. In general, the EVP system was evaluated as an effective and highly practical tool that improves emergency-vehicle mobility, arrival-time stability, and operational reliability across diverse dispatch conditions. The combined quantitative and qualitative verification in this study underscores its value as a field-proven technology. Future studies should expand to multiregional longitudinal datasets, controlled analyses considering external variables such as traffic volume and weather, and quantitative evaluation of safety-related impacts such as reductions in intersection collisions or on-route risk exposure to assess the system’s broader policy and operational benefits more comprehensively.

As renewable energy penetration continues to increase, the output variability and forecasting uncertainty of photovoltaic generation have emerged as major operational risks in power systems. This study establishes a sensor-based data quality control procedure to ensure the reliability of meteorological data collected at a PV plant. For temperature, humidity, and wind speed, a four stage QC process physical range check, persistence check, step change check, and median filtering was applied. Solar radiation, which exhibits strong temporal and distributional characteristics, was processed using a three-stage QC procedure consisting of physical range, step change, and frequency distribution checks. Using the quality-controlled meteorological data, PV generation forecasting was performed with SVM and XGBoost models. As a result, the MAPE values improved to 6.32% for SVM and 6.08% for XGBoost after QC application. The findings confirm that meteorological data quality control significantly enhances PV forecasting accuracy and can support future strategies for distributed energy resource management, curtailment mitigation, and power system risk reduction.

In 2015, the safety refresher training system for seafarers was reformed with the aim of strengthening practical skills. However, a failure to forecast demand led to a chronic backlog of trainees. Furthermore, the uniform application of merchant vessel standards (STCW) to fishing vessels (STCW-F) created a qualitative problem, undermining the effectiveness of the education. This study aims to diagnose these issues and propose effective improvement measures. This research employed a mixed-methods approach. First, a comparative analysis was conducted between international conventions (STCW and STCW-F) and domestic regulations, institutional standards, and curricula. Second, an empirical analysis was performed through a survey of 220 merchant and fishing vessel seafarers, which was supplemented by in-depth interviews. The analysis revealed several critical gaps. The domestic legal framework does not distinguish between STCW and STCW-F and the curriculum is heavily biased toward theory, failing to meet international practice-oriented competency standards. The survey and interview results confirmed that the current fits all training is severely misaligned with the operational realities of fishing vessels, which have different equipment and environments. Based on these findings, this study proposes three prolonged improvement plans. First, the curriculum should be dualized to reflect the distinct characteristics of merchant and fishing vessels. Second, a hybrid training model that combines mandatory shore-based training for high-risk drills with flexible onboard training for basic skills should be introduced. Third, facility standards for training institutions should be converted from rigid mandates to flexible guidelines. These measures are expected to resolve the chronic training backlog and enhance the practical emergency response capabilities of all seafarers.

The 30mm wheel type anti-aircraft gun replaces the aging anti-aircraft gun in the front and is a weapon system for local anti-aircraft defense against enemy aircraft and small unmanned vehicles. In the field, damage to the turret hatch/closed hatch pin occurred between the operation of the wheel type anti-aircraft gun. As a result of the sem analysis of the hatch pin fracture surface, it appears that brittleness fracture occurred and fatigue fracture occurred at the final fracture surface while reaching the fatigue strength by repetitive loads. The hatch angle fixing pin and bracket shapes were changed to disperse the stress concentration. As a result of checking the location of the vulnerable area of the hatch pin and the shear stress value through structural analysis, the safety factor improved from 1.46 to 2.95 after improvement. Through this study, it is expected to be used as a reference material for failure analysis and design plan for the existing system in the future.

항공기와 여객선과 같은 대형 여객 운송의 핵심 가치는 안전이며, 안전관리를 위해 국제조약을 기반으로 제정된 규칙에 따라 명시된 인원 이상의 훈련받은 승무원이 탑승해야 하는 공통점을 가지고 있다. 참사로 이어졌던 항공기와 크루즈 여객선 사고사례 분석을 통해 승무원의 역량과 교육 및 매뉴얼 관리가 안전에 지대한 영향을 미치고 있음을 확인하였으며, 사고 이후 관리부서를 일원화하고, 법 조항의 신설 및 강화와 함께 승무원 안전교육의 중요성이 대두되었다. 그러나 사고를 예방하고 비상 상황에 즉각 대응하기 위해서는 안 전교육 과정과 방식의 변화가 필요하며 이를 통해 교육 효과를 높여 승무원이 정확히 대응할 수 있도록 해야 한다. 첫째, 수직 형태의 구 조와 비슷한 공간의 반복, 화재 방지를 위해 닫힌 구조인 여객선의 공간적 특성은 여행객들이 쉽게 탈출하기 어려운 구조다. 따라서 이는 승무원의 공간적 이해의 중요성을 시사하며 탈출 교육에 확대 반영될 필요가 있다. 둘째, 항공기에 비해 승객의 이동 공간이 큰 여객선의 여객선 승무원의 비율을 높여, 안전관리 수행이 가능한 환경을 조성해야 하며 법률로 규제할 필요가 있다. 셋째, VR, 사이버, 메타버스 등 을 활용한 교육방식의 변화를 통해 승무원의 교육 효과를 높이고 실습 중심의 교육이 되어야 한다. 사고 사례분석을 통해 여객선 승무원 교육방식 및 방향 개선에 시사점을 제시했다. 이를 통해 대부분의 안전사고에 원인으로 지목된 인적요인 즉, 승무원의 안전관리 역량의 향상과 함께 대한민국 크루즈사업의 안전성 확보 및 완전한 성장에 기여하려 한다.

본 연구는 해양오염의 주요 원인이면서도 관리의 사각지대에 놓여있는 어선 폐유 문제에 주목하였다. 어선 발생 해양오염 사 고는 전체의 43%를 차지하고 있으나, 해양환경관리법에 따른 오염방지설비 설치 등의 의무가 면제되고, 사후 단속 위주의 단편적 관리만 이루어지는 한계가 있다. 이에 우리나라의 어선 폐유 관리 실태를 분석하고, 미국, 일본, 유럽연합(EU)의 관리체계를 ‘불법배출 상시 감 시’, ‘기관간 협업’ 및 ‘인센티브 관점’에서 비교하여, 국내 실정에 맞는 소형어선의 효율적인 관리 방안을 검토한다. 이것을 통해 해양환 경 범죄로서 불법배출 예방에 관한 형사정책적 관점에서 ‘첨단 기술 기반의 과학적 단속’, ‘경제적 인센티브 중심의 제도 지원’, ‘협업을 통한 DB 공유’을 검토하여 불법배출의 상시 감시와 적법처리의 인센티브 방안을 도출한다. 그리고 이러한 방안을 국내 실정에 적합한 구 체적 이행방안으로 ▲인공위성 및 AI 기반의 첨단 감시 시스템 구축, ▲해양오염물질 보증금 제도 및 수거ㆍ처리 인프라 스마트화, ▲현 장접점에 있는 수협과 해양경찰 간 폐유관리 DB 공유 등 협업체계 마련을 제언한다. 이러한 정책들이 실효성을 가지기 위해서는 첨단 기 술 기반 증거의 법적 실효성이 중요하며, 이를 위한 형사법적 정당성에 관한 연구가 필요하다. 또한, 제안된 제도의 수용성을 높이기 위해 서 어민들의 현실적 어려움을 반영한 지속 가능하고 현장에서 작동가능한 정책연구가 병행되어야 한다.

본 연구는 MTS가 피부개선에 미친 영향에 관한 기존 연구들을 분석하여, 근거 체계를 구축하고, 주요 키워드 간 관계와 역할 및 패턴 등을 구조적으로 분석하고자 텍스트마이닝과 토픽모델링 및 단어네트워크 분석을 실시하였다. 관련 선행연구들은 MTS와 관련된 핵심 키워드와 연관 키워드를 혼합하여 전자도서관에서 검색하였으 며, 결론 부분의 Text를 수집하여 분석에 사용하였다. 분석결과는 다음과 같다. 첫 째, '피부', '효과', '실험', '관리', '개선' 등의 어휘가 주요 개념으로 확인되었다. 둘째, TF-IDF 분석에서 높은 가중치의 키워드들은 MTS의 피부 개선 효과에 관한 과학적 실험 기반 논의를 시사했다. 셋째, LDA 분석 결과, ‘과학적 검증 중심’과 ‘피부 개선 효과 중심’의 토픽2개로 나뉘었다. 넷째, 단어 네트워크에서 '피부'를 중심으로 '주름', '효과', '실험' 등이 강하게 연결되었고, '여성'과 '모공' 노드는 MTS가 여성 안면 부위 에 주로 적용됨을 나타냈다. 본 텍스트마이닝 기법은 유사 의료 미용 시술 분석에도 적용 가능하며, 향후 시계열 분석과 감성 분석을 통해 MTS 효과의 변화와 대상자 반응을 심층 탐색할 필요가 있다.

Priority should be considered to encourage businesses to participate by activating the low-noise machine certification system. However, the domestic low-noise machine certification system has not yet been significantly activated. There is a need for a system that only products that meet the environmental sign certification standards for low-noise construction machinery are recognized as "low-noise machines". A compliance evaluation agency (CAB) in the field of low-noise equipment should be introduced in Korea to help facilitate international certification of domestic company products. Therefore, it is believed that it will help expand the supply of low-noise machines through technology development and export improvement.

2008년부터 해양환경관리법에 의해 시행되어 온 해역이용협의 및 해역이용영향평가제도가 분법되어 2025년 해양이용영향평 가법으로 시행되었다. 해양이용협의와 해양이용영향평가의 일부 대상사업에 대하여 변경되었으며, 그 중에서 일반해양이용협의 대상사 업인 해수 인·배수 사업의 특정 규모(관 지름 400 mm 이상이고, 관 길이가 150 m 이상이고, 관의 점용면적이 3,000 m2 이상)와 공유수면 을 점·사용하는 부선 설치 사업(무동력장치, 60일 이내)을 간이해양이용협의 대상으로 지정하여 기존 적용 범위를 완화하였다. 그럼에도 불구하고, 간이해양이용협의서의 작성방식, 작성자의 전문성 결여, 현황파악을 위한 해양환경자료의 부실 등과 같은 문제점이 여전히 남 아있다. 따라서, 본 논문에서는 해양이용영향평가법의 적용을 받는 과거 간이해역이용협의 대상사업의 유형을 파악하고, 간이해양이용 협의서 작성 시 문제점 분석과 함께, 개선방안을 제시하고자 하였다.

기후위기 대응과 탄소중립 실현을 위한 전략으로 해상풍력발전이 주목받고 있 으며, 한국 정부도 이를 국가 에너지 정책의 핵심 축으로 삼아 대규모 확대를 추진 중이다. 그러나 해상풍력은 어업, 환경, 지역사회 등 다양한 해양 이용 주 체들과의 이해 충돌 속에서 추진되고 있으며 이로 인한 갈등은 사업 지연 또는 무산으로 이어지는 사례가 늘고 있다. 본 연구는 해상풍력 발전과 관련된 법 적·사회적 갈등 중에서도 어업손실 보상제도에 초점을 맞추어 현행 제도의 문제점을 분석하고 제도 개선 방향을 제시하였다. 연구 결과 현재의 어업손실 보상제도는 법적 근거가 미흡하고 보상 대상 범위 가 제한적이며, 손실 산정 기준 역시 현실과 괴리가 크다는 문제가 확인되었다. 특히 민간사업자의 경우 법적 보상 협의 의무가 명확하지 않아 사업자와 어민 간 갈등이 장기화되고 있다. 해외 주요국 사례(영국, 대만, 덴마크)를 분석한 결 과 이들 국가는 제도화된 협의 절차, 어민 참여형 평가 시스템, 정교한 피해 산정 기준을 통해 갈등을 최소화하고 있었다. 이에 본 논문은 해상풍력 어업손실 보상제도의 법제화, 현실적 산정 기준 마련, 어업 증빙을 위한 정보화 기반 구축을 핵심 과제로 제안한다. 이는 단순한 보 상을 넘어 지역사회와의 상생과 지속가능한 해상풍력 확산을 위한 제도적 기 반이 될 수 있다.

This study was attempted to solve the problem that the current training is not consistent with the actual working environment of the fishing vessel, even though the advanced fire extinguishing training for international fishing vessels is mandatory. As a result of the survey, the lack of timely use of fire extinguishing equipment and the difficulty of organizing the fire extinguishing organization were found, and the main problems were analyzed as low understanding of fixed fire extinguishing facilities, low awareness of fire-related laws and regulations, and inefficiency of fire extinguishing training. It was found that the current Seafarers Act does not clearly define the roles and responsibilities of advanced fire extinguishers, and lacks specific standards for designated educational institutions, so there is a problem that the accuracy and reliability of the training contents with the STCW-F Convention and STCW Convention are inconsistent. In addition, it has been confirmed that the fire extinguishing organization, internal communication, and fire extinguishing training in ships, as stipulated in international agreements, are not properly reflected in the domestic curriculum. In particular, the current training consists of general contents that do not take into account the characteristics of fishing vessels, so there is a lack of practical emergency response fire extinguishing training manuals. Therefore, this study proposes the development of customized training content for fishing vessels considering the special working environment and risk factors of fishing vessels based on international agreements, and emphasizes the need for policy support, such as strengthening participation of fishing vessels in education and training, and establishing a legal basis for the operation of emergency fire extinguishing organizations.

This study aims to enhance the efficiency of the after-sales service (A/S) process for commercial trucks by implementing a data-driven approach. Traditional A/S methods result in long repair wait times, especially for intermittent faults requiring symptom reproduction. To address this, a system that records Diagnostic Trouble Code (DTC) and Vehicle Running Mode (VRM) data at failure moments is proposed. By storing data from 10 seconds before and after an event, fault diagnosis can be performed without symptom reproduction. Additionally, for exported vehicles, stored data enables remote analysis, overcoming real-time data limitations due to varying environmental factors. This approach improves maintenance reliability, optimizes repair accuracy, and supports proactive quality improvements for newly developed vehicles.

This study attempted to solve the problem that the current education does not match the actual working environment of the fishing vessel despite the mandatory lifeboat training of international fishing vessel. The survey analyzed the difficulties of using life rafts and communication facilities and found that the main problems were the launch of life rafts, lack of communication equipment proficiency, and absence of emergency training scenarios. Due to the lack of standards for designated educational institutions, the current Seafarers Act has been discovered to be a problem that the accuracy and reliability of education are not consistent with the international fishing vessel agreement and the merchant vessel agreement. Additionally, the training for retreat and emergency response as stipulated by international agreements were not properly reflected in the domestic curriculum. In particular, the current training consists of general contents without considering the characteristics of the fishing crew, and there was a lack of practical emergency response training manuals. Therefore, based on international agreements, this study proposes the development of customized training contents for fishing vessel that takes into account the special working environment and risk factors of them. In addition, it emphasizes the need for policy support, such as strengthening participation of fishing boats in education and training and establishing a legal basis for the operation of emergency life raft organizations.
