Purpose: Professional quality of life is the quality one feels in relation to their work as a helper. The purpose of this study was to describe professional quality of life among emergency nurses. Methods: A total of 15 emergency rooms were selected in three cities. Among 263 nurses working at these emergency rooms, 178 nurses consented to participate in this cross-sectional survey. Professional Quality of Life (ProQOL) Scale version 5 was used to measure compassion satisfaction, burnout and secondary traumatic stress. Cluster analysis was used to classify nurses according to professional quality of life. Results: The mean scores (SD) for compassion satisfaction, burnout, and secondary traumatic stress were 32.12 (5.45), 28.27 (4.28), and 28.20 (5.07), respectively. The result of cluster analysis according to standardized score of compassion satisfaction, burnout, and secondary traumatic stress yielded three clusters. Over 50% of participants showed low professional quality of life. Nurses who were included in a cluster representing low professional quality of life were younger, had shorter periods of nursing experience, and perceivedlower social support than other cluster. Conclusion: Education or support programs for emergency nurses are needed to enhance their professional quality of life.

Currently, the development of multimedia communication has progressed so rapidly that the video program service has become a requirement for ordinary customers. The quality of experience (QoE) for the visual signal is of the fundamental importance for numerous image and video processing applications, where the goal of video quality assessment (VQA) is to automatically measure the quality of the visual signal in agreement with the human judgment of the video quality. Considering the codec effect to the video quality, in this paper an efficient non-reference (NR) VQA algorithm is proposed which estimates the video quality (VQ) only by utilizing the distorted video signal at the destination. The VQA feature vectors (FVs) which have high relationships with the subjective quality of the distorted video are investigated, and a hybrid NR VQA (HNRVQA) function is established by considering the multiple FVs. The simulation results, testing on the SDTV programming provided by VCEG Phase I, show that the proposed algorithm can represent the VQ accurately, and it can be used to replace the subjective VQA to measure the quality of the video signal automatically at the destinations.

The complexity arises in defining the construction quality due to its perception, based on inherent market conditions and their requirements, the diversified stakeholders itself and their desired output. A quantitative survey based approach was adopted in this constructive study. A questionnaire based survey was conducted, for the assessment of construction quality perception and expectations in the context of quality improvement technique. The survey feedback of professionals, from the leading construction organizations/companies of Pakistan were analyzed. The financial capacity, organizational structure, and construction experience of the construction firms formed basis for their selection. After statistical analysis of survey feedback it was found reliable and valid for the inferential purpose to the target population of construction professionals. The quality perception was found to be project scope oriented, considered as an excess cost for a construction project and keeping the rework minimum by qualifying the required quality tests, keeping the defects minimum by ensuring the specifications of supplied material. Any quality improvement technique was expected to address the financial aspects of the construction project for the employer and contractor, by increasing the profitability through reduction in overall cost, reduction in time, reduction in defects and improving the productivity in a construction project. The study is beneficial for the construction professionals to assess the prevailing construction quality perception and the expectations from implementation of any quality improvement technique in construction projects.

Objectives : In studying East Asia's medical classics, what must first be done before evaluating the validities of clinical grounds is the discernment of the techniques that are based on universal principles from the statements that arise from individual experience. The purpose of this paper is to discover a method of discerning the statements of individual experiences and the descriptions of universal principles. Ingredients and Methods : The paper investigates how each individual clinical experience was introduced in ancient medical classics such as Huangdineijing, Nanjing, Shanghanlun, Jinkuiyaolue, and Maijing, in the books that belong to Yian such as Canggongliechuan, Linzhengzhinanyian, Gujinyianan, and Xumingyileian, and in Korean ancient medical texts such as Eonhae-gugeubbang and Gugeubganibang-eonhae. Results : Books of precriptions and scriptures of medicine were found to include individual experiences. Furthermore, this paper's effort has revealed that the evaluation of the quality of a testimony in an ancient book must be preceded by discerning whether the said testimony is a mere personal testimony or a testimony based on the universal law of causality. Conclusions : Before conducting a clinical research of a precription contained in an East Asian medical classic, the text should first be evaluated to determine whether the prescription in question derives from clinical tests or not.

In order to realize the virtual prototyping (VP) of digital products, it is important to provide the people involved in product development with the appropriate visualization and interaction of the products, and the vivid simulation of user interface (UI) behaviors in an interactive 3D virtual environment. In this paper, we propose an approach to web-based 3D virtual experience using Unity and Leap Motion. We adopt Unity as an implementation platform which easily and rapidly implements the visualization of the products and the design and simulation of their UI behaviors, and allows remote users to get an easy access to the virtual environment. Additionally, we combine Leap Motion with Unity to embody natural and immersive interaction using the user's hand gesture. Based on the proposed approach, we have developed a testbed system for web-based 3D virtual experience and applied it for the design evaluation of various digital products. Button selection test was done to investigate the quality of the interaction using Leap Motion, and a preliminary user study was also performed to show the usefulness of the proposed approach.

Purpose: The purpose of this study was to identify and describe nurses' experience of a career ladder program (CLP) in a general hospital in Korea. Methods: The data were collected from 15 nurses who participated in the CLP. Each nurse completed individual in-depth interviews, for which the main interview question was "How do you describe your experience of CLP?" All interview data were transcribed and were analyzed using the grounded theory method. Results: The core category of the experience of CLP was identified as "challenging to rebirth as an expert". The participants used five action/interaction strategies such as "taking some time for introspection", "appreciating the essence of nursing", "making use of feedback positively", "throwing away doubts about their own capabilities", "exerting themselves with confidence". The consequence of the process of adjusting to CLP was "positioning a differentiated expert". Conclusion: The results of this study show that participants recognized CLP as a powerful resource which leads them to professional growth and development. Thus, CLP could be utilized as a clinical career-promoting program and ultimately as a program for providing high-quality nursing services.
