Purpose: This study investigates the level of nursing professionalism and factors that affect nurse perceptions. Method: This study is a descriptive study involving 443 nursing students from two universities. Data were collected in September 2012 via a structured self-report questionnaire and subsequently analyzed using descriptive statistics, t-tests, one-way ANOVA, Pearson correlation coefficients, and multiple regression. Results: The mean scores for nurse image, core elements of nursing professionalism and nursing professionalism were $3.65{\pm}.46$, $4.17{\pm}.39$ and $3.59{\pm}.45$, respectively. Nursing Professionalism had a significant positive correlation with nurse image (r=.749, p<.001) and core elements of nursing professionalism (r=.365, p<.001). In multiple linear regression, factors that influenced nursing professionalism were: temperament as nurses, professionalism, vision of career, role performance of nurses' image, and fundamental nursing practical experience. These variables explained about 58.8% of the total variance in nursing professionalism. Conclusion: For more positive nursing professionalism among students, more attention should be paid to enhancing the positive image of nurses. Doing so can serve as a fundamental resource for the development of appropriate strategies for nursing professionalism.

Corrosion of embedded reinforcing bars is recognized as being the major cause of deterioration of reinforced concrete structures. With regard to maintenance strategies of concrete nuclear structures, the monitoring of cracking remains of primary importance. Recently, authors have developed a post-treatment technique to extract crack features from continuous computations. In this paper, such technique is applied to carry out a numerical analysis of an accelerated corrosion test. Obtained results allow highlighting specific propagation and failure mechanisms that characterize corrosion-induced cracking.

This work presents an assessment of the computational performance of a vector-parallel implementation of probabilistic model for concrete cracking in 3D. This paper shows the continuing efforts towards code optimization as reported in earlier works Paz, et al. (2002a,b and 2003). The probabilistic crack approach is based on the direct Monte Carlo method. Cracking is accounted by means of 3D interface elements. This approach considers that all nonlinearities are restricted to interface elements modeling cracks. The heterogeneity governs the overall cracking behavior and related size effects on concrete fracture. Computational kernels in the implementation are the inexact Newton iterative driver to solve the non-linear problem and a preconditioned conjugate gradient (PCG) driver to solve linearized equations, using an element by element (EBE) strategy to compute matrix-vector products. In particular the paper analyzes code behavior using OpenMP directives in parallel vector processors (PVP), such as the CRAY SV1 and CRAY T94. The impact of the memory architecture on code performance, and also some strategies devised to circumvent this issue are addressed by numerical experiment.

Theoretical foundations of the knowledge management(KM) have been perceived still developing in the field. And, the literature shows many key success factors for KM, but, in more conceptual and abstract term. Companies interested in knowlege management demand for practical guidelines. Based on the constituent elements of KM, this study classifies key success factors identified from thirty three success cases, domestic and in other countries. Further, fifteen propositions are suggested and discussed for future research and project management in KM.

Patient education is one of the most important roles of a physical therapist. Physical therapists have to teach and provide information about illness, instruct for home exercise, and give advice relating to correct posture and daily activities et al. For an efficient education some strategies are required. The purpose of this article is to review general learning methods, to introduce elements that influence the procedure of patient education and learning, and to plan an education strategy.

Satellite formation flying is the placing micro-satellites with the same mission into nearby orbits to form a cluster. Clohessy-Wiltshire equations are used to describe the relative motion and control strategies between satellites within a cluster, which are known as Hill's equations. Even though Hill's equations are powerful in determining initial conditions for the satellite formation flying, they can not accurately express the relative motion under J2 perturbation. Some methods have been developed for the determination of initial conditions to avoid limits of Hill's equation. This paper gives a new method of determining initial conditions using mean elements. For this research mean elements were transformed to osculating elements using Brouwer's theory and the orbit was propaeated with the consideration of J2-J8 to get a relative position. The results show that satellites within a cluster are maintained in the desired boundary for long period and the method is effective on a fuel saving for satellite formation flying.

The objectives of this study are, first to define the concept of restaurant total coordination and establish its components as a design strategy for planning and managing all elements comprising a restaurant, and second, to survey the total coordination of Japanese restaurants in foreign countries and examine how traditionality, which is an element for globalizing Japanese restaurants, is expressed. This study was conducted through literature review for defining the concept of restaurant total coordination and extracting its components and a field survey for analyzing the current state of restaurant total coordination and traditionality expression methods. The results of this study are as follows. First, Japanese restaurants categorized into Type A with relatively high traditionality expression(3.3 or higher) were 25% of the surveyed restaurants. These restaurants showed the traditional characteristics of Japanese style as they are without contemporary adaptation for all components of restaurant. Second, 41.7% of the restaurants were categorized into Type B with traditionality expression between 1.7 and 3.3. They were mostly popular casual restaurants at which people can enjoy Japanese food comfortably. In visual and spatial design elements, traditional and contemporary styles appeared in the equal percentage, and decoration, table setting and food design were styled according to Japanese traditions. Third, 4 cases(33.3%) were categorized into Type C with traditionality expression below 1.7. Because they were fine dining restaurants that sold high priced dishes, formality and consistency were also high. Through all design elements including visual, spatial, table setting and food design elements, elegant and simple contemporary images were dominant. The results of this study will be used as basic materials to establish the concept of total coordination that views the visual, spatial, table setting and food design elements comprising a restaurant, which were approached separately in previous studies on restaurants, together from the viewpoint of integrative deigns, and to make design strategies for globalizing Korean restaurants based on Japanese restaurant cases.

본 연구의 목적은 '탄소저감형 도시재생' 개념의 정립과 계획 요소 도출, 계획 체계의 구축에 있다. 탄소저감형 도시 재생 계획요소 도출을 위해 '도시재생' 계획요소와 '저탄소도시' 계획요소 간의 상호연관성 분석(Matrix Analysis)과 전문가 집단면접(FGI)을 실시했고, 이를 통해 도출된 요소들을 재구조화시켜 계획 체계를 구축했다. 또한, 도출된 탄소저감형 도시재생 계획 요소 및 체계의 적절성 및 그 효과를 검증하기 위해 심층사례분석을 실시했다. 분석 결과, 탄소저감형 도시재생 계획요소는 총 5개 분야 37개의 요소로 설정되었고 검증단계를 통해 분석해 본 결과, 계획 체계 및 요소들은 선진 사례에서도 매우 핵심적으로 적용되어 있었으며 도시재생 및 탄소저감에 기여하는 효과도 매우 적극적인 것으로 나타났다. 또한 이들은 탄소저감 뿐만 아니라 기후변화의 적응과 완화(억제)의 측면에서도 매우 긍정적으로 작용했다. 재생 측면에 적극적 효과를 보이는 요소들은 주로 공간구조 및 교통, 제도 및 프로그램에 관한 것들이었고 탄소저감 효과가 큰 요소들은 교통, 녹지 및 수자원, 에너지 및 자원 분야에 속해있었다. 또한, 현재와 같은 추세의 기후변화 및 화석에너지 고갈이 계속될수록 도시재생사업에서의 탄소감축은 지속가능한 개발의 '환경적'측면 뿐만 아니라 '경제적'측면에도 매우 중요한 역할을 감당하게 된다는 것을 분석할 수 있었다.
