주 5일제 근무, 개인 여가문화 확산, 국민 소득 증대 등으로 인해 해양을 레저의 목적으로 이용하는 사람들이 증가하고 있으며, 이러한 이용객의 증가에 따라 사고 발생의 개연성도 함께 증가하고 있는 상황이다. 우리나라에서는 선박을 이용한 레저활동의 경우에는 안정장비의 착용을 의무화하고 있지만, 연안 해역에서의 해양활동에 대하여는 안전장비 착용 의무화가 시행되지 않고 있다. 따라서, 본 연구에서는 연안 이용객에 의한 사고통계 데이터 분석을 바탕으로 연안 이용객의 안전장비 착용의 필요성에 대하여 고찰하였다. 또한, 분석된 내용을 바탕으로 안정장비 착용 의무화 방안에 대하여 제안하였다.

이 연구는 인천광역시 소재 사회복지시설에 근무하는 사회복지사 274명을 대상으로 2015년 5월 및 7월에 실시한 설문조사 결과 중 사회복지사들이 겪은 인권침해와 불이익 경험 여부 및 영향요인을 분석하였다. 이를 위하여 이 연구는 인권침해는 상사나 동료 및 클라이언트의 폭언, 폭력, 성희롱의 경험으로, 불이익은 임금과 수당, 복리후생, 기관운영에서의 차별로 구분하였다. 로지스틱 회귀분석 결과, 이 연구는 사회복지사가 여성일수록, 연령이 낮을수록, 기혼자일수록, 고용형태가 비정규직일수록, 근로시간은 길수록 인권침해와 불이익을 경험하게 되는 확률이 상대적으로 높으며, 대학원 이상의 학력 소지 사회복지사의 경우 불이익 경험 보다 인권침해 경험을 받을 가능성이 높은 것으로 확인하였다. 또한, 이 연구는 사회복지사들은 인권침해 경험에도 불구하고 직장 내에서 이를 문제로 제기한 경우는 10.3%에 불과한 것도 확인하였다. 전국 및 기초지자체 차원에서 사회복지사의 근로환경과 인권침해에 관한 조사연구가 있는 상황에서, 처음으로 광역지자체차원에서 이를 분석한 이 연구는 사회복지사의 인권침해와 불이익의 예방과 피해구제를 위한 적극적 조치가 필요하다는 의견도 제시하였다.

선사 이래 인류의 대표적 고대 문화유산의 하나가 금석문이다. 이런 금석문들은 다양한 과학적 기법들로 그 원 형태를 인식하고자 하는 노력을 하고 있다. 그러나 가장 오래되고 유용한 보존과 인식 방법은 탁본에 의한 것이다. 그러나 원 자료의 심각한 훼손으로 탁본자료의 형상 인식이나 문자 인식은 일반적인 이미지 복원 방법과는 다양한 면에서 차이를 보이고 있어 이의 노이즈를 제거하고 원이미지를 복원하여 형상을 인식하는 것이 중요하다. 이러한 탁본의 판독에는 다양한 잡음들이 있어 이를 전문적인 판독가 들도 이설을 제기하는 경우들이 있다. 다양하고 심각한 훼손 상태에 있는 탁본의 이미지들은 다양한 형태의 심각한 노이즈를 가지고 있어 전통적이고 일반적인 이미지 향상이나복원 기법들을 적용하기에 적절하지가 않다. 본 연구에서는 구름이나 야간 상황 등 다양한 노이즈를 가진 SAR 이미지처리 기법과 다양한 환자들의 다양한 병적 상태의 이미지들에 효과적으로 적용되는 방법들을 살펴 탁본 문자인식에 적용하고 그 효과를 히스토그램과 이미지 엔트로피를 이용하여 측정하고자 하였다.

코로나 팬데믹 이후 원격근무와 클라우드 업무환경으로의 전환이 가속화되었다. 이러한 급격한 변화로 인해 기존 보안 모델의 문제점이 드러났고, 이를 해결하기 위해 미국을 포함한 여러 국가들이 제로트러스트(Zero-Trust) 기반 보안 모델을 제안하고 있다. 그러나 제로트러스트 기반 보안 모델은 많은 기관의 실질적인 환경으로 직접 적용하기는 매우 어려운 현실이다. 이는 많은 국가들이 제안하는 제로트러스트 기반 보안 모델은 보안 원칙과 구현에 대한 가이드만 제공할 뿐, 적용하는 기관의 상황을 고려한 보안 운영 방안을 제시하지 않고 있어 직접 적용하기에는 한계가 있다. 따라서 본 논문에서는 기관의 제로트러스트 기반 보안 체계 도입을 위한 사이버 보안 프레임워크의 설계 방안을 제안하고자 한다.

This study was conducted to evaluate the moral distress, moral sensitivity, and the factors that influence moral distress and the experience of moral distress among nurse working in a long-term care hospital. Overall, 180 nurses working in long-term care hospital in G Province were evaluated. Date were collected from March 21 to April 8, 2016 and analyzed using the SPSS/WIN 23.0 program. The mean of moral distress among nurses was 3.57 and the moral sensitivity was 4.82, and these factors was significantly and positively correlated (r=0.494, p<0.001). Regression analysis revealed that the factors that significantly influenced moral distress were moral sensitivity and ethical dilemmas when conducting nursing practices. Situations that caused nurses to experience moral distress included inappropriate care behavior was not guaranteed the quality of nursing care, conditions related to unethical the human rights, conditions related to the lack of nursing staff and conditions related to the lack of support at the organizational and national level. Therefore, to reduce moral distress, nursing intervention programs that improve the moral sensitivity and ability to solve ethical-problems are needed for nurses working in long-term care facilities.

The present study examined the causal relationships among nurses' perceived autonomy, job satisfaction, work environment (work overload, role conflict, situational support, head nurses' leadership), personal aspects(experiences, need for achievement, professional knowledge and skill) by constructing and testing a theoretical framework. Based on literature review nurses' perceived autonomy and job satisfaction were conceived of as outcomes of the interplay among work environment and personal characteristics. Work environment factors involved work overload, role conflict, situational support, and head nurses' leadership (task oriented leadership, relation oriented leadership). Personal charateristics included experiences, need for achievement, and professional knowledge and skill. Three large general hospital in Chonbuk were selected to participate. The total sample of 516 registered nurses represents a response rate of 92 percent. Data for this study was collected from July to September in 1998 by Questionnaire. Path analyses with LISREL 7.16 program were used to test the fit of the proposed conceptual model to the data and to examine the causal relationship among variables. The result showed that both the proposed model and the modified model fit the data excellently. It needs to be notified, however, that path analisis can not count measurement errors; measurement error can attenuate estimates of coefficient and explanatory power. Nevertheless the model revealed relatively high explanatory power. 42 percent of nurses' perceived autonomy was explained by predicted variables; 32 percent of nurses' job satisfaction was explained by by predicted variables. Tn predicting nurses' perceived autonomy the findings of this study clearly demonstrated the work overload might be the most important variable of all the antecedent variables. Head nurses' relation oriented leadership, situational supports, need for achievement, and role conflict were also found to be important determinants for nurses' perceived autonomy. As for the job satisfaction, role conflict, situational supports, need for the achievement, and head nurses' relation oriented leadership were in turn important predictors. Unexpectedly the result showed perceived autonomy have few influence on job satisfaction. The results were discussed, including directions for the future research and practical implication drawn from the research were suggested.

Decrease in crew performance is frequently cited as a major causal factor in maritime accidents. Although considerable researches on working hours undertaken by seafarers have been conducted through interviews and record analyses, experimental studies on the effects of factors, such as high workload, shift patterns, stress, sleep deprivation, and disturbance on the cognitive performance of mariners have been limited. Other safety-critical transport industries, such as aviation and rail, have developed fatigue management tools to help managements in the work patterns of their operators. Such tools for mariners would assist shipboard crews, marine pilots, and shore managers for planning and improving work schedules. The overall aim of this paper is to determine a fatigue factor that can be applied to human performance data as a part of a software program that calculates total cognitive performance. This program enables us to establish the levels of cognitive performance in a group of marine pilots in order to test a decision-making task based on radar information. This paper addresses one of the factors that may contribute to the determination of various fatigue factors: the effects of different work patterns on the cognitive performance of a marine pilot.

This study aims to confirm whether both the emotional labour and job stress contribute to the turnover intention of infant teacher. The correlation analysis and parametric analysis were sequentially performed for our study. Analyzed results showed that the emotional labour was related to the job stress and turnover. Also, a statistical significance between the job stress and turnover intention was observed. Besides, the job stress partially mediated the relation between the emotional labour and turnover intention. Nsidering that the emotional labor of teacher caring or lived with infants occurred inevitably, our study proposed three approaches to reduce the job stress that partially mediated relation between the emotional labour and turnover intention. Generally, the infant teacher with excellent qualification produced the good education. Therefore, we suggested that the it was necessary that a work environment had been improved and working motivation was ameliorated to employ the infant teacher with excellent qualification.
