The fishing industry is globally recognized as a high-risk sector with substantial safety challenges. This study analyzes Norway's fishing vessel safety management legislation and risk management practices. The goal is to derive insights that can enhance South Korea's safety management for fishing vessels. Norway has established a culture of safety through regular inspections, mandatory safety training, the implementation of safety management systems, and active involvement of fishermen in risk assessments. These measures have significantly reduced maritime accidents. This study suggests incorporating effective elements of Norway’s safety management into the South Korean context, emphasizing a participatory approach that actively involves fishers.

양식장 환경관리를 위하여 여러 나라에서 양식장 환경관리시스템을 구축하고 있으며, 어장환경평가가 그중 하나이다. 2013년에 개정된 국내 어장관리법에는 어류가두리양식장 면허를 연장할 때 어장환경평가를 받도록 명시되어 있다. 어장환경평가는 과학적 분석을 통한 평가를 바탕으로 양식장 환경 개선 조치를 실행하여, 지속 가능한 어업생산 조성, 어장 생산력 증가, 어업인의 소득 증가를 목적으로 한다. 어장환경평가의 평가지표는 저서다모류 군집을 기초로 한 생물지수인 저서동물지수(BHI)와 총유기탄소량(TOC)이며, 두 항목을 점 수화하여 단일등급으로 산출하여 평가에 사용한다. 본 연구는 어장환경평가지표인 BHI와 TOC의 선정 과정과 산출된 평가 등급의 생태학 적 의미를 설명한다.

본 논문은 2020년 2학기, 각 대학에서 시도하였던 “실시간 온라인 수업” 경험에 대한 설문을 진행한 결과를 토대로 작성되었다. 이는 추후 온라인 기반 수업이 어떠한 방향으로 나아가야 하는가를 진단하고, 한문 교육은 어떠한 점을 염두에 두는 것이 바람직한가를 살피기 위함이었다. 이를 위해 실시간 온라인 수업이 차지한 비중과 사용한 플랫폼을 파악하고, 그 개선점에 대해 설문 내용을 중심으로 분석을 시도하였다. 우선, “비중”에 있어서는 100% 비대면 수업 중 과반수 이상의 과목에서 실시간 온라인 수업을 진행하였음을 알 수 있었다. “플랫폼”의 경우, 인문계열에서는 “줌(ZOOM)” 플랫폼에 대한 사용이 압도적으로 높았으며, “1대 1 채팅” 및 “소회의실” 기능이 긍정적인 평가를 받고 있음을 확인하였다. 마지막으로 “개선점”으로 지적된 소통의 부재와 집중도 하락 문제를 보완할 수 있는 방안으로 구체적 한문과 수업 방안을 소개하였다. 제한된 인원으로부터의 설문 조사 내용에 기반하고 있는 본 연구 내용을 일반론으로 단정하기에는 한계가 있다. 그럼에도 불구하고 중복적으로 제기되고 있는 문제에 대해서는 대안을 고민해야 한다고 생각하여 본 연구를 진행하였다. 또한 한문수업에 특화된 구체적이고 다양한 모델에 대해서 간략하게 소개하였는데, 이에 대한 보다 구체적인 연구는 후고를 기약한다.

Spermatozoa viability can be assessed by microscopy, flow cytometry, and other methods using fluorescent stain. Flow cytometry can be used to examine the morphological and functional characteristics of spermatozoa in a short time. The purpose of this study was to compare the viability of cryopreserved spermatozoa in Jeju black cattle by two dual fluorescent stain methods. Semen of Jeju black cattle raised in Subtropical Livestock Research Institute, National Institute of Animal Science, RDA were collected with artificial vaginal technique. Sperm was diluted with Triladyl®-egg yolk diluent and then was performed cryopreservation.There was no significant difference in viability of spermatozoa according to the two dual fluorescent stain methods. However, when the distribution of spermatozoa according to the staining method was compared, the spermatozoa group stained with 6-CFDA/PI was more clearly distinguished than the spermatozoa group stained with calcein AM/PI.

Current seismic design provisions such as ASCE 7-10 provide criteria for selecting ground motions for conducting response history analysis. This study is the sequel of a companion paper (I – Ground Motion Selection) for assessment of the ASCE 7-10 criteria. To assess of the ASCE 7-10 criteria, nonlinear response history analyses of twelve single degree of freedom (SDF) systems and one multi-degree of freedom (MDF) system are conducted in this study. The results show that the target seismic demands for SDF can be predicted using the mean seismic demands over seven and ten ground motions selected according to the proposed method within an error of 30% and 20%, respectively

For estimating the seismic demand of buildings, most seismic design provisions permit conducting linear and nonlinear response history analysis. In order to obtain reliable results from response history analyses, a proper selection of input ground motions is required. In this study, an accurate algorithm for selecting and scaling ground motions is proposed, which satisfies the ASCE 7-10 criteria. In the proposed algorithm, a desired number of ground motions are sequentially scaled and selected from a ground motion library without iterations.

We investigated the distribution of asbestos in Seoul for 16 school buildings built before and after 1990, includingkindergartens, elementary schools, middle schools and high schools. The risk assessment standards of AHERA,HSE and ASTM were reviewed and a comparative analysis of assessment standards was conducted in schoolbuildings. For the risk assessment of 16 schools, 170 samples were selected, each of which was assessed usingstandards of AHERA, HSE and ASTM. The school buildings included the ACM (asbestos containing materials)ranged 3-4% of chrysotile and 1-3% of amosite in classroom ceilings and has 7-8% chrysotile in partitions of studenttoilets. The airborne concentrations of fiber materials were ranged with 0.002-0.022 fiber/cc in school buildingsby PCM. In this study, a simplified rating scale was used three categories of Good, Damaged and SignificantlyDamaged. In the result of comparative analysis for the risk assessment criteria, it was found that 113 samples, 132samples and 82 samples were classified as Good when assessed by AHERA, HSE and ASTM, respectively; and46 samples, 29 samples and 53 samples as Damaged, respectively; and 12 samples, 8 samples and 34 samples asSignificantly Damaged, respectively. From the distribution of asbestos and the comparative analysis for the riskassessment criteria, the management plan and new risk assessment were made based on the Korea backgroundshould be established to control asbestos exposure to students from damaged ACM and will be revealed that theassessment for the current condition and potential for disturbance on asbestos in school buildings.

Bacterial soft rot is one of the major disease of Zantedeschia species (Calla lily) caused by Erwinia carotovora. The objectives of this study were i) to screen the most efficient method to determine resistance level against E. carotovora and ii) to evaluate the genetic variability in Zantedeschia genotypes by inoculation of Ecc NHRI-3 and PD 1784 isolates. Four screening tests i.e. leaf disk, petiole, tuber and tuber slice tests were used to determine the resistance level in calla lily. Eleven genotypes from section Zantedeschia were used for variation studies against E. carotovora by using the leaf disk test. It was observed that all genotypes showed variation in resistance level and could be categorized in 3 groups on the basis of their resistance level. Four of the genotypes were resistant against this pathogen whereas, 6 genotypes were moderately resistant and only one genotype was found susceptible. Within section Aestivae, ‘Galaxy’, ‘Florex Gold’, ‘Treasure’ and ‘Mango’ were found very susceptible cultivars, whereas ‘Coral Sunset’, ‘Hazel Marie’ and ‘Neroli’ were less susceptible genotypes. Most of the cultivars from section Aestivae were susceptible to bacterial soft rot and the cultivar ‘Florex Gold’ was identified as susceptible control. It is suggested to perform pre-screening through leaf disk method which proved to a non-destructive test. The pre-screening evaluation can discriminate susceptible cultivar and resistant cultivar. Tuber slice test is more useful in screening subsequent genotypes at a later growth stage in any breeding program.

물관리 정책이 수질평가 중심에서 수생태계 건강성 평 가로 전환되고 있는 것은 세계적인 추세이다. 현재까지 수계의 평가기법은 수질이나 하상구조와 같은 물리화학적 요소 및 플랑크톤, 저서동물과 같은 일부 생물의 평가 에 국한되어 개발되어 왔다. 식물은 호수의 물리, 화학 및 생물 변화를 민감하게 반영하는 지표인데 개발이 늦었 다. 환경부에서는 전국의 호수와 저수지를 생태계로써 평 가하고 관리할 목적으로 생태계의 평가 기법을 마련 중 에 있다. 이 연구사업의 일환으로 식물을 이용하여 우리 나라 호수생태계에 적합한 건강성 평가기법을 개발하기 위해서 기개발된 국외의 평가기법 중 주로 다변수법을 주로 고찰하였다. 다변수법의 적용은 시간과 비용이 많이 소요되고 변수 간의 상관성 등의 한계점이 있다. 그러나 현재 단일 변수로 쓸 만한 지표가 개발되어 있지 않으며 다변수법은 다면평가와 데이터 축적의 장점이 크다. 다변 수법을 세 단계, 즉 평가지표의 선정, 점수화, 평가지수의 결정과 검증단계로 나누어 검토하였다. 평가지표 선정단 계에서 가장 적용가능한 지표는 종조성과 수도 및 종 풍 부도와 다양성 관련 지표들이다. 국외에서 대부분 포함하 는 지표종은 아직 개발이 불완전해서 우리나라에서 적용 하기에 한계가 있다. 다수 조사자가 참여할 경우 식물상 에 대한 오동정이 결과에 영향을 미칠 수 있으므로 이 점의 사전 고려가 필요하다. 지표의 점수화 단계도 한계 가 있다. 우리나라에 인위적 교란이 거의 없는 기준 호수 가 없기 때문에 대안으로 다수의 호수를 조사하고, 조사 된 호수의 지표값을 상대화하여 적용해야 한다. 같은 이 유로 지수에 대한 검증과정도 어렵다. 종합할 때, 여러 가 지 한계가 있지만 현장에서 조사 가능한 지표를 이용하 여 식물을 이용한 호수 건강성의 다변수평가체계를 구축 하는 것은 가능하다. 추후, 식물종의 질적 가치에 대한 지 표를 추가하고 보다 많은 호수 조사의 결과가 누적되면 수준 높은 평가체계로 발전시킬 수 있을 것이다.
