본 연구의 목적은 대학생의 생명의료윤리 특성과 자존감과의 상관관계를 알아보고, 보건계열과 비보건계열 대학생의 생명윤리의식 간에 차이를 비교하는 것이다. 연구대상자는 일개 대학의 보건계열과 비보건계열을 포함한 대학생 651명으로 생명윤리의식과 자존감에 대해 2015년 5월 2주간 조사하였다. 그 결과 자존감은 생명의료윤리인식과 유의한 상관관계가 있는 것으로 나타났으며, 자존감이 높은 대학생이 생명의료윤리를 중요하게 생각하는 것으로 나타났다. 그러나 보건계열과 비보건계열의 생명의료윤리 인식을 비교한 결과 생명공학을 제외한 안락사, 뇌사 등에는 유의한 차이를 보이지 않았다.

This paper introduces an automated method for building height recovery through the integration of high-resolution satellite images and digital vector maps. A cross-correlation matching method along the vertical line locus on the Ikonos images was deployed to recover building heights. The rational function models composed of rational polynomial coefficients were utilized to create a stereopair of the epipolar resampled Ikonos images. Building footprints from the digital maps were used for locating the vertical guideline along the building edges. The digital terrain model (DTM) was generated from the contour layer in the digital maps. The terrain height derived from the DTM at each foot of the buildings was used as the starting location for image matching. At a preset incremental value of height along the vertical guidelines derived from vertical line loci, an evaluation process that is based on the cross-correlation matching of the images was carried out to test if the top of the building has reached where maximum correlation occurs. The accuracy of the reconstructed buildings was evaluated by the comparison with manually digitized 3D building data derived from aerial photographs.

질의 키워드의 출현 빈도수가 높은 문서를 검색하면 키워드의 의미가 다양하여 정확한 정보를 인지하지 못하며, 기존 검색 시스템의 온톨로지 구성만으로는 검색된 문서들이 사용자의 요구에 부합되지 않는 문제점을 가진다. 본 연구에서는 시맨틱 웹 기술을 기반으로 인사관리에서 인선에 필요한 다양한 개념들과 지식으로 구성된 인선 온톨로지와 인선 규칙들을 구축하고 이들을 지원하는 인선 절차와 인선 결과의 적합성을 확인할 수 있는 시스템을 제안한다. 또한, 이를 기반으로 비모수적 상관 계수를 이용하여 음성 정보를 추출하는 방법을 사용하여 평균 SNR이 0.752dB 감소됨을 보임으로써 제안한 방법의 우수성을 확인하였다.

본 연구는 24시간 환자와 함께 하며 감염병 유행시 가장 많은 부담을 느끼는 병원 간호사를 대상으로 병원 간호사의 COVID-19에 대한 불안과 우울 정도를 알아보기 위해 시행되었다. 연구대상은 수도권 소재 300병상 이상의 종합병원 5곳에 근무하는 간호사 232명이었고 자료수집은 2020년 8월부터 2020년 9월까지 진행되었다. 수집된 자료는 기술통계, t-test, ANOVA, Pearson's correlation coefficient로 분석하였다. 연구결과 질병 이환에 대한 불안은 8.03점, 우울은 14.45점으로 나타났다. 질병 이환에 대한 불안과 우울은 양의 상관관계(r=26, p<.001)가 있었다. COVID-19가 장기화되고 있는 현 상황에서 간호사의 코로나 바이러스 감염증(COVID-19)에 대한 질병 관련 불안과 우울을 탐색하고 이들의 불안과 우울을 완화하기 위한 관리가 필요하다.

본 연구의 목적은 복막투석환자의 우울, 자기효능감, 치료순응도 정도를 파악하고 이들 변수간의 관계를 파악하기 위함이다. 본 연구는 B광역시의 대학병원을 내원하는 복막투석환자 139명을 대상으로 설문조사한 자료를 SPSS 25.0 프로그램을 이용하여 분석하였다. 본 연구에서 자기효능감은 약물복용, 수분제한, 치료식이의 치료순응도와 정적 상관관계가 있으며 우울은 약물복용, 치료식이의 치료순응도와 부적 상관관계가 있었다. 따라서 복막투석환자의 치료 순응도를 강화시키기 위한 간호전략은 자기효능감의 증진과 우울의 완화에 중점을 두어야 할 필요가 있다.

The purpose of this study was to investigate the relationship between personality, positive psychological capital, and academic resilience of nursing students and to identify the factors affecting academic resilience of nursing students. Data were collected from 199 nursing students in their first and second year at C nursing college in M-gun, J-do, and a survey was conducted from July 10 to July 28, 2023. The collected data were analyzed using descriptive statistics, t-test, one-way ANOVA, Scheffe test, Pearsons correlation coefficient, Stepwise multiple regression analysis was conducted. Personality had a significant positive correlation with positive psychological capital(r=.62, p<.001) and academic resilience(r=.68, p<.001), and positive psychological capital had a significant positive correlation with academic resilience(r=.79, p<.001). The major factor influencing the academic resilience of nursing students was positive psychological capital, followed by personality, interpersonal relationship, and college life satisfaction, and their total explanatory power was 72% (F=102.85, p<.001). Based on the results of this study, it is necessary to develop an educational program that can increase positive psychological capital in order to strengthen the academic resilience of nursing students, and efforts should be made to introduce and manage it in the nursing curriculum.

Biomass and community composition of microphytobentos in tidal flats were studied by HPLC analysis and also investigated to examine the relationship between microphytobenthic pigments and Adenosine-5' triphosphate (ATP) as an index of total microbial biomass in intertidal environments (muddy and sandy sediment) of Gyeonggi Bay, west coast of Korea. Microphytobenthic pigments and ATP concentration in muddy sediment were the highest at the surface while the biomass of microphytobenthos in sandy sediment was the highest at the sub-surface (0.75 cm sediment depth). The detected pigments of microphytobenthos were chlorophyll a, b (euglenophytes), $c_3$, peridinin (dinoflagellates), fucoxanthin (diatom or chrysophytes), diadinoxanthin, alloxanthin (cryptophytes), diatoxanthin, zeaxanthin (cyanobacteria), ${\beta}$-carotein, and pheophytin a (the degraded product of chlorophyll a). Among the pigments which were detected, the concentration of fucoxanthin was the highest, indicating that diatoms dominated in the microphytobenthic community of the tidal flats. There was little significant correlation between OC (Organic Carbon) and ATP in both sediments. However, a positive correlation between chlorophyll a concentration and ATP concentration was found in sandy sediment, suggesting that microbial biomass could be affected by labile OC derived from microphytobenthos. These results provide information that may help us understand the relationship between microphytobenthos and microbial biomass in different intertidal sediment environments.
