  • Background: Although sick leave is a complex phenomenon, it is believed that there is potential for prevention at the workplace. However, little is known about this potential and what specific measures should be implemented. The purpose of the study was to identify perceived reasons to take work-related sick leave and to suggest preventive measures. The study was completed before the COVID-19 pandemic emerged, and the risk factors identified may have been amplified during the pandemic. Methods: An in-depth cross-sectional survey was conducted across a randomly selected sample of hospital nurses in Norway. The national sample comprised 1,297 nurses who participated in a survey about their sick leave during the previous 6 months. An open-ended question about perceived reasons for work-related sick leave was included to gather qualitative information. Results: Among hospital nurses, 27% of the last occurring sick leave incidents were perceived to be work-related. The most common reasons were high physical workload, high work pace, sleep problems, catching a viral or bacterial infection from patients or colleagues, and low staffing. Conclusions: Over a quarter of the last occurring sick leave incidents among Norwegian hospital nurses are potentially preventable. To retain and optimize scarce hospital nursing resources, strategies to reduce work-related sick leave may provide human and financial benefits. Preventive measures may include careful monitoring of nurses' workload and pace, optimizing work schedules to reduce the risk of sleep problems, and increasing staffing to prevent stress and work overload.

  • A three-dimensional windshield display (3D-WSD) can present driving information at the same depth as the objects in the outside scene. Herein, a super-multiview 3D-WSD is proposed because the super-multiview display technique provides smooth motion parallax. Motion parallax is the only physiological cue for perceiving the depth of a 3D image displayed at a far distance, which cannot be perceived by vergence and binocular parallax. A prototype system with 36 views was constructed, and the discontinuity of motion parallax and accuracy of depth perception were evaluated.

  • The purpose of this research was to reveal how Korean food is currently perceived by the "foodies" of New York City and to determine what social status Korean food has in the city that is deemed the "Restaurant Capital of the World." In-depth personal interviews were performed to provide a deeper insight into the comments and subject matters. Most foodies selected kimchi and Korean barbecue as the most distinctive foods in Korean dining. Korean food's distinguishing traits were extracted in four areas: specific ingredients and tools, preparation procedures, and rules. Sensory characteristics, local adaptation, service, side dishes, and the main strengths and short-comings of Korean foods were investigated. Perception toward the taste of Korean food was generally positive, but poor quality of service and lack of organization in establishments were found to be negative factors.

  • Purpose - Salesperson perceptions of the fairness and accuracy of a performance evaluation system were examined by managerial and professional employees of large organization. The performance evaluation process is central to many personal decisions such as attitude for job and sales performance. This study investigates the relationship between perceived evaluation fairness, job satisfaction, organizational commitment, and sales performance. The main purpose of this study is to develop and empirically test a comprehensive model of salespersons' perceived evaluation fairness on sales performance. For this purpose, we identified the structural relationship between perceived evaluation fairness, job satisfaction, organizational commitment, and sales performance. Also we investigate the mediating effects on job satisfaction and organizational commitment between perceived evaluation fairness and sales performance. Research design, data, and methodology - To empirically test these relationships, data were collected by in-depth interviews from sales managers and questionnaire surveys from 300 salespersons who work for sales area (credit card company, insurance company). Demographically, the overall sample was 91.6% female, 77.9% 30s and 40s, and 34% college educated, with an average tenure with their present organizations of 4 years. The questionnaire was composed of total 20 items dealing with frequency, quality, and consequences of perceived evaluation fairness, job satisfaction, organizational commitment, and sales performance. To test the research hypotheses, collected data analyzed by confirmatory factor analysis (CFA) and structure equation model (SEM). Results - Through extensive and rigorous literature review process of related literature(Perceived evaluation fairness, Job satisfaction, Organizational commitment, Sales performance), research model and research hypothesis was set up. This study obtains the following research results. First, perceived evaluation fairness has a positive effect on job satisfaction, whereas the effects of perceived evaluation fairness on organizational commitment and sales performance did not show statistically significant result. Second, job satisfaction and organizational commitment have complete mediating roles to the relationship between perceived evaluation fairness and organizational commitment, and relationship between perceived evaluation fairness and sales performance. Conclusions - Based on the results, salespersons' perceived evaluation fairness is one of the key independent variable for making high job satisfaction, organizational commitment, and sales performance. Finally the theoretical, managerial implication and research limitations are mentioned in the discussion.

  • 입체시 계산 모형들은 국지적으로 대응 가능한 여러 대상들이 있는 경우 가설적인 부등 탐지기들간의 상호 작용을 통해 대응될 대상을 결정한다. 이 연구에서는 인간의 양안시 기제도 입체시 모형들의 가정과 유사하게 부등 탐지기들의 활성화 수준에 따라 대응될 대상을 선택하는 지를 알아보기 위해서 깊이가 다른 두 표면을 가지는 무선점 패턴을 입체 그림으로 사용하였다. 응시 표면과 같은 깊이에 놓여 있는 표면을 구성하는 점들은 무선적으로 선택되었으며(원 무선 패턴) 이 표면보다 앞에 놓여있는 표면을 구성할 점들은 원 무선 패턴의 각 점들과 다음과 같은 방식으로 짝지어졌다. 원 무선 패턴을 구성하는 점들의 위치를 발견하여 왼쪽 입체 그림에서는 무선 점들의 왼쪽 3분에 오른쪽 입체 그림에서는 무선 점들의 오른쪽 3분에 위치하도록 하여 6 분의 깊이에 해당하는 또 다른 표면을 만들었다. 원 무선점 패턴의 자기를 고정시킨 채 새로운 패턴의 밝기를 변화시키면 가설적인 탐지기들의 상대적인 활성화 수준이 서로 달라질 것을 추정할 수 있다. 상대적인 활성화 수준에 따라 대응될 대상이 변화되는 지를 알아보기 위해서 모든 점들의 위치는 고정시킨 채 두 표면을 구성하는 점들간의 상대적인 밝기를 변화시켜가면서 각 밝기 수준에서 두 표면의 깊이를 측정하였다. 쌍을 이루는 점들간의 밝기 차가 30% 이내인 조건에서는 3 분의 부등에 해당되는 하나의 표면이 지각되었지만, 두 점의 밝기가 타이가 날수록 이 표면 이외의 다른 표면과 더불어 모두 두개의 표면이 지각되었다. 특히 새로운 표면의 깊이는 무선점 패턴을 구성하는 점들과 추가된 점들의 상대적 밝기에 따라 달라겠다. 추가된 점들이 밝은 조건에서는 이 점들의 부등에 해당되는 깊이를 갖는 표면이 원 무선점 패턴이 밝은 조건에서는 무선점 패턴의 부등에 해당되는 깊이를 가진 표면이 추가적으로 지각되었다. 이러한 결과는 보다 활성화 된 탐지기들이 약한 탐지기들을 억제하여 있음을 시사한다.

  • A Typically-Perceived-Situation(TPS) is a situation which might be useful for conceptual learning of science, rising spontaneously in an individual's mind when someone is thinking about, or in relation to, any object such as physical object, concept, situation, etc. But, for a discussion about the TPS' usefulness in depth, we need to analyze the specific features of the TPS in relation to conceptual learning of science. This study investigated four elementary school students' TPSs related to the topic of the action of force, especially (a) 'the situation where force is being acted on an object', and (b) 'the situation where force is not being acted on an object', with an interview as well as with a drawing-and-explanation type questionnaire. Their TPSs were then compared with their concepts, checked by a misconception questionnaire of choice-and-explanation type. The results showed that the students' TPSs illustrated not only their conceptions about the action of force, but also gave more fruitful details of their ideas, including (a) clues of their conceptions, (b) concrete situations, and (c) their past experiences with emotional components. On the whole, the TPS's appeared to be rather stable, affected by their past experiences, and needed to be analyzed into their sub-units for more subtle details. Finally, some practical ways of how to apply the ideas of the TPS to the conceptual learning of science are suggested.

  • 3D 영화 콘텐츠처럼 고해상도로 만들어진 입체영상은 저해상도 영상에서는 동일한 3D 깊이감을 느낄 수가 없다는 단점이 있다. 본 논문에서는 공간적 복잡도을 이용하여 깊이맵을 변환하여 입체감을 개선할 수 있는 방법을 제안한다. 제안 방법에서는 깊이맵의 히스토그램을 분석한 후에, 깊이맵을 다수의 깊이평면으로 분할한 다음에 깊이 평면을 변환한다. 마지막으로 변환된 깊이평면을 통합하여 최종 깊이맵을 생성한다. 주관적 평가 실험에서는 입체감 개선 및 이에 따라 발생하는 시각적 피로도를 검증하였다. 실험에서는 입체감의 개선이 증명되었으며, 영상 해상도가 낮아져도, 입체감은 유지되는 것을 보여주었다. 또한 얻어진 입체영상의 시각적 피로도 검증을 통해서 생성된 입체영상은 피로도가 증가하지 않는 것을 보여주었다.

  • 2차원적 이미지에 생동감 있는 3-D 깊이감을 구현하기 위한 노력은 입체 지각에 대한 이론적 이해 및 그에 따른 기술적 발전과 더불어 오래 동안 지속되어 왔다. 본 논문에서는 입체경을 사용한 입체시 구현 원리에 기반을 둔 대중적인 입체경들을 간략히 개괄하고, 이들 중 액티브 셔터 방식의 입체경이 사용된 시각기억 실험 사례를 소개하였다. 실험에 참가한 피험자들은 자극들의 지각된 깊이를 기억하였으며, 이에 대한 기억 정확도가 측정되었다. 기억 및 검사를 위한 항목들의 깊이감은 1) 단안, 2) 양안 그리고 3) 단안과 양안 단서가 사용된 조건으로 각기 달리 처치되어 구분되었다. 참가자들의 기억 수행은 양안단서만이 처치된 조건에서 가장 낮았던 반면, 양안단서와 단안단서가 동시에 구현되었을 때 가장 높았다. 이러한 결과는 시각기억이 깊이 정보를 저장할 때, 양안단서를 통해 구현된 정보보다 단안 단서를 통해 구현된 정보를 더 효율적으로 저장하며, 양안단서와 단안단서가 동시에 사용되었을 때 가장 효과적인 기억 수행이 가능함을 시사한다.

  • Purpose: This study was conducted in order to explore home visiting therapists' self-perceived role, problems, and supplement points of the home-based rehabilitation (HR) program based on the community-based rehabilitation (CBR) model. Methods: Four home visiting physical therapists, who conducted the HR program, participated in this study. After completion of the HR program, in-depth interviews were conducted using a semi-structured questionnaire for participants to explore their self-perceived role, problems, and supplement points of the HR program. Results: Participants regarded the role of the HR program as for "the linkage between recipient & society", "maintenance & improvement of recipients' physical function", and "education of recipient about the way of self rehabilitation". The problems and supplement points were derived from all phases of the HR program, including "human & material resources", "training program for human resources for HR service", "selection of recipient of HR service", "contents of the intervention for HR service", and "duration of HR service". Conclusion: These findings indicate that participants well recognized the intention of the HR program based on the CBR model, and suggest that high-quality human resources with rich expertise and experiences, a training program for HR service led by experts, and selection of recipients led by experts are necessary for an effective HR program. In addition, strategies and capacities specified to HR service should be identified, and applied to the training program for human resources for HR service. The results of this study could provide useful information when the government decides on the next guideline for home visiting health service.
