하천 내에서 하상변동은 치수나 생태계에 직간접적인 영향을 끼치는 것으로 알려져 있다. 하상변동의 예측을 위한 여러 가지 모델들이 존재하지만 하상변동의 양상을 직관적으로 파악하기에는 어려움이 있다. 최근 수행된 연구결과에 따르면 하천의 수리 기하학적 형상이 부유사 농도와 유량과의 관계와 관련이 있는 것으로 밝혀졌다(Kim et al., 2018). 본 연구에서는 하상변동과 부유사의 농도를 밀접한 관련이 있다고 가정하여 수리기하(Hydraulic Geometry) 이론을 이용하여 하상변동의 경향성을 표현하여 하상변동의 경향성을 직관적으로 유추할 수 있는 기법을 제시하고자 한다. 이를 위해 본 연구에서는 하상변동을 수리기하적표현을 이용하여 해석적으로 제시하였고 수치모의를 실시하였으며 실제 자연하천에 대해 검증을 수행하였다. 수치모의는 자연에 존재할 수 있는 다양한 하천형상을 표현하기 위해 수리기하 이론에서의 수심과 폭을 나타내는 인자들을 이용하여 하천의 형상을 넓고 얕은 하천, 좁고 깊은 하천, 중간 정도의 하천으로 분류하였으며 흐름조건을 정상류와 부정류조건으로 분류하였다. 또한 하상경사와 하상재료의 입경분포를 고려하였다. 그리고 실제 하천에 대한 검증은 대한민국에 존재하는 갑천, 미호천, 남강, 임진강, 원주천, 금호강의 하상변동 자료를 이용하여 실시하였다. 하상변동의 경향성을 직관적으로 표현하기 위해 Manning 공식을 이용하여 하상전단력의 수리기하 지수를 수심, 유속, 조도계수의 수리기하지수들로 표현하였다.

Gist-based message design is essential in the Internet in which a lot of health messages are created and shared constantly. This study intended to identify the characteristics of health messages in a webzine and explore a way to design gist-based health messages. A total of 72 webzine articles published in Korean Ministry of Food and Drug Safety were selected, and text and visual messages of the articles were analyzed in terms of content types, the frequency and position of gists, and intuitive expression. The articles were also categorized regarding the characteristics of health messages through cluster analyses. This study found that most texts of the health articles consisted of facts and methods, while most visual messages represented concepts. In addition, both text and visual messages had limitations in presenting a gist effectively. It was also necessary to explore an effective way to improve an intuitive understanding of jargon and quantitative information in health messages. Based on these findings, this study provided suggestions for the design of gist-based health messages in the Internet.

The purpose of this study was to investigate the factors affecting job satisfaction of nurses in nursing care service ward. The subjects were 127 nurses, nursing job satisfaction, nursing intuition, and nursing work environment using the 5 - point Likert scale. Data were analyzed by t-test, ANOVA, correlation and regression analysis using SPSS WIN 23.0 program. The results showed that the correlation between job satisfaction and independent variables in nursing and nursing care service ward was significant in nursing professionalism (r = .90, p <.001) and nursing work environment (r = .75, p <.001). In addition, factors affecting job satisfaction were in the order of nursing professionalism and nursing work environment (F = 31.516, p <.001), and explanatory power was 84.1%. Therefore, Therefore, the necessity of nursing convergency strategy for improvement of these is suggested.

This study is a descriptive research study to confirm the relationship between nurse image, major satisfaction, nursing professionalism, and anxiety of nursing students who experienced COVID-19. Data was collected from May to July 2022. The participants were 230 nursing students in S-city, Gyeonggi-do. As a result of the study, the participantt's nurse image showed a positive correlation with nursing professionalism (r=.635, p<.001) and major satisfaction (r=.581 p<.001), and nursing professionalism and major satisfaction (r=.504, p<.001) was found to be positively correlated. There was a negative correlation between nursing professionalism and anxiety (r=-.143, p=.030). As a result of this study, nursing students who experienced COVID-19 should seek various intervention programs to increase nurse image, major satisfaction, and nursing professionalism and lower anxiety.

컴퓨터 시뮬레이션을 통한 자연스러운 가상 성형은 컴퓨터 그래픽스와 애니메이션 분야의 오래된 연구 주제이다. 본 논문은 2D 가상 성형 시스템 용도의 가변 워핑 마스크를 이용한 시그모이드 블렌딩 방법을 제안함으로써 가상 성형의 품질 만족도와 편의성 및 실용성을 제고함에 그 목적이 있다. 제안된 2D 가상 성형 시스템은 마우스로 스머지 필터를 조작하여 얼굴 구성 요소의 윤곽 형상을 원하는 형태로 변형할 수 있는 직관적인 사용자 인터페이스를 제공한다. 얼굴 구성 요소의 스머징 전후의 윤곽선을 대상으로 다각형 근사화에 기반한 계층적 제어선 매핑을 통해 획득한 제어선 쌍들을 이용하여 반자동 필드 워핑을 수행함으로써 소스 제어선으로부터 목표 제어선까지 점진적으로 변해가는 다수의 중간 프레임들을 생성한다. 또한 이 반자동 필드 워핑을 수행할 시, 성형 부위의 변형을 따라 단계적으로 모양이 변하는 가변 워핑 마스크를 사용함으로써 변형 부위 이외의 얼굴 구성 요소들에 대해서는 왜곡을 최소화하는 지역적 변형 특성을 제고하고, 이렇게 생성된 성형 부위를 가변 모핑 마스크의 경계 영역에서 시그모이드 함수에 기반한 블렌딩을 수행하는 것이 특징이다. 제안된 2D 가상 성형 시스템은 직관적이고 편리한 사용자 인터페이스를 제공할 수 있기 때문에 시간이 적게 소요되고 작업 피로도가 낮아 실용성이 높다. 특히 짧은 시간 내에 성형의와 고객이 만족하는 직관적인 상담을 가능케 하는 것이 장점이다.

This study was undertaken to identify nursing professionalism perceptions among nursing students who had completed a semester of simulation-based education, and to provide the basis for presenting direction of the simulation curriculum that helps in the emergence of a positive nursing professional in future. Data obtained from focus group interviews of study participants determined 17 semantic categories and 6 themes through the process of identifying, comparing, and categorizing meaningful concepts. The perception of nursing students regarding the profession after simulation-based education include 'realization of professionalism', 'ethics and emotions as professional human subjects', 'cultivation of communication skills', 'integrative thinking for problem solving', and 'foundation', and also the importance of a 'foundational knowledge body' and 'reflection of self-capacity'. The results of this study reflect on 5 intuitional areas of a nursing professional: professional self-concept, social awareness, nursing expertise, nursing room role, and independence of nursing. The results of this study indicate that in order to enable nursing students to experience nursing professional intuition through simulation-based hands-on training, it is necessary to actively revise and apply courses for the development of a positive nursing professional intuition through simulation education.

In this paper we propose a new method of security visualization, VisFlow, using traffic flows to solve the problems of existing traffic flows based visualization techniques that were a loss of end-to-end semantics of communication, reflection problem by symmetrical address coordinates space, and intuitive loss problem in mass of traffic. VisFlow, a simple and effective security visualization interface, can do a real-time analysis and monitoring the situation in the managed network with visualizing a variety of network behavior not seen in the individual traffic data that can be shaped into patterns. This is a way to increase the intuitiveness and usability by identifying the role of nodes and by visualizing the highlighted or simplified information based on their importance in 2D/3D space. In addition, it monitor the network security situation as a way to increase the informational effectively using the asymmetrical connecting line based on IP addresses between pairs of nodes. Administrator can do a real-time analysis and monitoring the situation in the managed network using VisFlow, it makes to effectively investigate the massive traffic data and is easy to intuitively understand the entire network situation.

This paper presents a semi-autonomous authoring method which can intuitively create 3D game/ animation contents for unexperienced users. In particular, this method considers their convenience to provide them with easier authoring environments. The 3D game/animation contents created by this method consist of several scene components connected to each other in a logical flow structure. Thus, it is possible to easily understand the overview of 3D content description for its production and manipulate these scene components for efficient management. Four different genres of game/animation contents have been developed by using an authoring tool based on this method. According to results of a survey intended for game developers who created game contents with the authoring tool, this method is shown to save contents development cost/time as well as raise the efficiency and convenience of whole process of contents creation to the expected level.

본 연구의 목적은 간호대학생의 진로준비행동에 미치는 영향요인을 규명하기 위함이다. 일 지역 159명의 간호대학생을 대상으로 자료수집은 2014년 9월 25일부터 10월 4일까지 진행되었으며 자료는 SPSS/WIN 21에 의해 분석되었다. 연구결과로는 간호전문직관, 전공만족도 및 긍정심리자본이 대상자의 진로준비행동에 양의 상관관계를 보였다. 진로준비행동에 영향을 미치는 요인으로는 전공만족도의 교과만족과 간호전문직관의 사회적 인식인 것으로 나타났다. 결론적으로 긍정심리자본은 비록 통계적으로 유의하지는 않았지만 앞으로도 대학생의 진로관련 변인과의 관련성을 규명하는 반복연구가 요구된다.
