The purpose of this study was to investigate the role of the Nypa fruticans extracts as a cosmetic additive. The tyrosinase inhibitory effects showed 52.0% at 1,000 ㎍/mL concentration. A cell viability test, measured on melanoma cell (B16F10) hot water extract of nypa fruticans showed 84.8% at 100 ㎍/mL concentration. The protein expression inhibitory effects of nypa fruticans extracts were measured by western blot at 25, 50, 100 ㎍/mL concentration and the β-actin. Results showed that the expression inhibition rates of the MITF, TRP-1, TRP-2, tyrosinase protein were decreased by 70.7%, 83.3%, 45.7%, 45.9% at 100 ㎍/mL concentration, respectively. It was concluded that nypa fruticans extracts had the whitening effects and thus could be applied for cosmetics as a natural ingredient.

고속도로 및 편의시설 건설로 불투수층의 면적이 증가하여 강우 시 고속도로 및 편의시설에서 발생하는 오염원에 의한 하천의 수질 영향도 커지고 있다. 특히 휴게소에서는 자동차의 급가속, 급감속으로 더욱 많은 분진과 오염물질이 발생할 수 있으며 타이어 마모 입자, 자동차 배기가스, 중금속 및 오일류 등이 휴게소나 도로 지표에 집적되어 있다. 이렇게 발생한 오염물질은 우기에 강우와 함께 불투수면을 침투하지 못하고 배수로를 통해 유출되어 인근 하천의 수생태 및 토양의 주요 오염원으로 작용하고 있다. 이에 따라 고속도로 및 인근 휴게소의 비점오염 저감대책이 필요하며 효율적인 비점오염원 저감을 위해 장기적인 모니터링, 지속적인 자료 수집 및 분석이 필요하다. 본 연구에서는 강원지역 고속도로 및 인근 휴게소에서 강우 시 강우유출수 모니터링을 통해 강우유출수 유량가중평균농도 (Event Mean Concentration) 산정하고 강우유출수 수문곡선 (hydrograph)을 작성하였다. 또한 강우사상에 따른 분석항목별 초기세척효과(First Flush Effects)와 오염부하량을 산정하였다. 추가적으로 차량 기인 입자를 확인하기 위해 μ-FT-IR 현미경 분석 실험을 하였다. 모니터링 장소는 휴게소 및 고속도로 일원이며, 모니터링은 선행무강우일수 2일 이상, 강우량 10mm 이상일 때 실시하였으며 2022년 6월부터 10월까지 총 4회 실시하였다. 모니터링 결과 타이어 및 브레이크 패드 마모와 관련된 중금속인 Zn, Cu, Pb 등의 중금속이 높게 분석되었으며 이러한 중금속의 오염부하량 역시 높게 산정되었다. 강우유출수 수문곡선에서 강우 초기 오염물질의 세척효과가 나타났다. MFFn 산정 결과 강우 30% 구간에서 초기세척효과를 보였다. μ-FT-IR 현미경 분석 결과 PE (Polyethylene)가 가장 많이 검출되었고 PP (Polypropylene), PS (Polystyrene) 순으로 검출되었다. 이러한 강우유출수 모니터링 데이터는 향후 고속도로 휴게소 및 고속도로 주변 오염저감 시설 설치 및 사회적 동참을 위한 타당한 근거 확보를 위한 기초자료로서 제공될 수 있을 것이다.

Purpose : This study aims to investigate the status of delirium intervention in adult intensive care unit (ICU) patients and the perception of this delirium by medical staff. Methods : This retrospective study involves 185 patients, whereas, a descriptive survey is conducted with 197 medical staff members. Results : The delirium group includes 100 patients (54.1%). The incidence of delirium is 64.9% in the medical ICU, 65.9% in the surgical ICU, 42.4% in the neuro ICU, and 46.5% in the cardiac ICU. The percentages of delirium prevention intervention differs between the two groups: 65.0% in the delirium group and 95.3% in the non-delirium group. The medical staff recognize that delirium is a common problem in the ICU (100.0%) and requires active medical intervention (98.5%). Conclusion : The length of stay at the ICU is longer in the delirium group than in the non-delirium group. It is necessary to standardize delirium prevention and treatment protocols to be equally applicable to all ICU patients.

Expressways play pivotal roles in cargo transportation because of their superior accessibility and mobility compared to rail and air. On the other hand, there is a limit to the accurate calculation of cargo transportation performance using existing highways owing to the mixture of vehicle types and difficulty in identifying cargo loads of individual cargo vehicles. This paper presents an algorithm for calculating more reliable cargo transportation performance using big data. The traffic performance (veh·km/day) was derived using the data collected from Toll Collecting System. The average tolerance weight for each vehicle type and the cargo load unit (ton/unit) considering it was calculated using vehicle specification information data and high-speed and low-speed axis data. This study calculated the cargo transportation performance by section and type using various online integrated highway data and presented a method for calculating the transportation performance by linking open business offices and private highways.

The aim of this study was to identify the influencing factors of nursing student' communication competence and practice stress on practice satisfaction in psychiatric nursing practice. The subjects of the study were 237 fourth-year nursing students. For data analysis, descriptive statistics, t-test, ANOVA, Pearson correlation coefficients, and multiple regression were performed using the SPSS/WIN 24.0 program. As a result of the study, communication competence was positively related with practice satisfaction, and practice stress were negatively related with practice satisfaction. In regression analysis, Role model, communication competence, major satisfaction, and associated education were confirmed as the predictive factors of psychiatric nursing practice satisfaction. It is required to develop teaching and learning methods to increase student satisfaction in psychiatric nursing practice.

White leg shrimps which were cultured in a private aquaculture farm showed abnormal swimming behavior and appetite reduction in July 2023. Then, gradual mortality was observed in the aquaculture farm. During the diagnosis, bacterial strain KNUAFVaSHP08147 was isolated from the hepatopancreas of the dead shrimps. Based on the sequence of 16S rRNA gene, KNUAFVa-SHP08147 was proved to be Vibrio alginolyticus, showing 99.71 % nucleotide identity with that of V. alginolyticus MG54 and GS MYPK1. According to the result of the growth of KNUAFVa-SHP08147, the treatment a commercial disinfectant, Virkon^TMS was not proved to be effective to prohibit the growth of Vibrio.

본 논문에서는 한국사회 내 2014년 이후 2022년 현재까지 진행되고 있는 다양한 생애주기별 재난안전교육 체계를 분석하여 재난 발생 시 자신의 생명과 재산을 보호할 수 있는 재난안전교육 인프라 구축을 위한 제언을 통해 시민 대상별 최적화된 재난안전교육 체계화를 모색하고자한다. 2014년 4월16일에 발생한 세월호 침몰 사고는 2015년 '재난 및 안전관리 기본법' 시행규칙의 일부 개정 및 이에 근거한 '국민안전의 날'이 국민안전의 중요성을 되새기자는 의미로 제정된 계기가 되었을 뿐만 아니라, 재난안전교육에 관한 전반적인 변화의 필요성을 깨닫게 해준 가슴 아픈 사건이었다. 이에 서울시 소방재난본부 현장대응단에서 2014년 말부터 시민대상 초기대응을 위한 재난안전 교육체계를 기획하고 10만의 안전리더 양성을 추진했다. 동시에 다양한 형태의 시민대상의 재난안전교육이 시, 도별로 진행되었다. 특히 서울 시민의 1%인 10만 시민안전파수꾼 양성을 위해 진행되었던 시민안전파수꾼 정책 사업을 위한 재난안전 교육체계는 시민을 대상으로 황금시간 목표달성을 통한 초기대응으로 재난규모를 최소화 할 수 있도록 안전에 관한 소양교육의 기본을 구성해 교육했고, 이는 시민 대상 재난안전교육의 방향에 대해 시사하는 바가 크다. 정책사업 초기 대학생 이상의 성인을 교육 대상으로 선정하여 교육이 진행되었고, 그 후 2018년 이후 고등학교 이상으로 교육의 대상범위를 확대하여 진행했지만 안전리더로서 역할은 한국사회 전체 구성원들의 인식이 필요한 부분으로 어린 시절부터의 반복 교육을 통한 안전문화가 시스템으로 구축되어 자연스럽게 습득되어 질 수 있도록 해야 한다는 필요성을 절감하게 되었다. 이에 다양한 생애주기별 재난안전교육 체계를 분석하여 국민스스로 재난 발생 시 자신의 생명과 재산을 보호할 수 있는 재난안전교육 인프라 구축을 위해 시민대상 재난 안전교육을 '황금시간 목표달성'을 준거틀로 기존의 중앙, 서울시, 부산시, 경기도 및 산하 교육청에서 실시해온 재난안전교육 체계 관련 문헌의 비교분석을 통해 시민 대상별 생애주기별 최적화된 초기대응을 위한 재난안전교육 체계를 모색하여 재난안전교육의 방향을 제시해 보고자 한다.

In this paper, the purpose of this paper is to predict and prevent the risk of crowd concentration in advance for possible future crowd accidents based on the Itaewon crush accident in Korea on October 29, 2022. In the case of a single CCTV, the administrator can determine the current situation in real time, but since the screen cannot be seen throughout the day, objects are detected using YOLOv4, which learns images taken with CCTV angle, and safety accidents due to crowd concentration are prevented by notification when the number of clusters exceeds. The reason for using the YOLO v4 model is that it improves with higher accuracy and faster speed than the previous YOLO model, making object detection techniques easier. This service will go through the process of testing with CCTV image data registered on the AI-Hub site. Currently, CCTVs have increased exponentially in Korea, and if they are applied to actual CCTVs, it is expected that various accidents, including accidents caused by crowd concentration in the future, can be prevented.
