Background: This study was performed to determine the experiences of nursing students in caring for paediatric cancer patients and their families. Materials and Methods: This qualitative survey was carried out with 14 students studying in the nursing department of the Faculty of Health Sciences of a university in Edirne, Turkey. Data were obtained through focus group interviews and evaluated based on a qualitative content analysis. Results: It was determined that students, for the most part, experienced problems related to communication, sadness, helplessness, fear, anxiety, resentment and anger. In addition, the students were affected most often by effects of the disease and invasive procedures on paediatric cancer patients and their families during the process of caring for them in the oncology clinic. Conclusions: It would be useful to inform nursing students, prior to clinical practice, about the special needs of paediatric cancer patients and families who stay in oncology clinics, and to follow up with appropriate guidance during the clinical practices.

Image segmentation is widely used in the pre-processing stage of image analysis and, therefore, the accuracy of image segmentation is important for performance of an image-based analysis system. An efficient image segmentation method is proposed, including a filtering process for super-pixels, improved saliency map information, and a merge process. The proposed algorithm removes areas that are not equal or of small size based on comparison of the area of smoothed superpixels in order to maintain generation of a similar size super pixel area. In addition, application of a bilateral filter to an existing saliency map that represents human visual attention allows improvement of separation between objects and background. Finally, a segmented result is obtained based on the suggested merging process without any prior knowledge or information. Performance of the proposed algorithm is verified experimentally.

In this paper, we propose a robust method which can detect and track a high-speed small approaching target in a cluttered environment for Korean Active Protection System. The proposed method uses a temporal and spatial filter, tracking filter to detect and track a single target in consecutive order. And it is comprised of a candidate target detection step, a prior target selection step and a target tracking. Field tests on real infrared image sequences show that the proposed method could stably track a high speed and small target in complex background and target occlusion.

This paper suggests the development device of Busan-Jinhae free Economic Zone(BJFEZ) to strengthen the competitiveness of the Port of Busan and promote the regional development in Busan. It deals with the securable feasibility of necessary sites and development costs and financial resources, the foreign investments figure, and the structure of the BJFEZ Authority. In addition, to evaluate the background, process, and contents of 'Special Purpose Local Government', the paper looks into the amendment proposal of 'Act on designation and management of free economic zones' suggested by the central government from the regional view of point. As proposals to promote and activate BJFEZ, it is recommended in the paper that it is required, first, to draw the detailed political methods to guarantee sound and sustainable development project and investment environment in accordance with regional characteristics prior to marketing, second, to develop and implement differentiated policy means to facilitate foreign investment, third, to strengthen specialty of the BJFEZ authority, and finally, to set up the supporting role and cooperation of both the central and local governments.

The voltage controlled ramp(VCR) waveform has recently been introduced in the reset period prior to addressing for plasma display. However, this method results in the oscillation of the gap voltage when the ramp rate is increased so as to reduce reset period. In this paper a current controlled ramp(CCR) waveform method in the reset period is suggested. This method can suppress the oscillation of gap voltage under the condition of shorter ramp time. Moreover, the reset time can be reduced by about 30 % compared with the VCR method under the same background luminance.

This paper aims to introduce the background history and development of records management in brief prior to and after the 1990s based on the records life cycle. This paper also explains the development of electronic document imaging systems and shifts to ERM systemsin the 1990s. The paper explains functional requirements in archival management and software application standards suggested by the industry of electronic records management. The paper concludes with providing problems and issues associated with software design in electronic records management for further development.

A new roof edge detection method based on multi level scales of wavelet function is proposed in this paper roof edge and its direction are obtained in this new methods at one time. Besides. scale characteristics of detecting roof edge is analyzed. And a few new methods on fingerprint image pre-processing are described. A method segmenting foreground/background of fingerprint images is proposed, in which Prior estimation of direction field is not required any more. A segmentation method based on multi-scale roof edges is implemented. and the valid scale range of the method is defined. too. And the method is used to segment ridges and valleys in fingerprint images simultaneously The exact direction fields made up of the direction of each point in ridges can be obtained when detecting ridges exactly based on the roof edge detector, in comparison with the traditional coarse estimation of direction fields. Obviously. it will establish a solid foundation for the sequent fingerprint identification.

This study aims to analyze users' assessment of electronic libraries in the mobile app market and promote service improvement based on this. To this end, the basic background and purpose of the research, research method, and research scope were first set, and the relevant literature and empirical prior studies were analyzed. Next, users' evaluations of electronic libraries were collected and analyzed from Google Play Store. Based on the results analyzed, measures to improve the quality of electronic libraries were discussed. Based on the results of the study, the following improvement measures are proposed. Need for systemic improvement and stabilization. Provision of applications suitable for multi-device environments. Resumption of services after systematic inspection after updating. Simplification of sign up, log in, and authentication procedures. User support through real-time chat. Introduction of a detailed assessment of reviews. Provision of guidance and user manual for electronic libraries. Improvements to expand user convenience, and Securing differentiation from other similar services.

The aim in this paper is to show how to extract scalp of a series of brain MR images by using region growing segmentation algorithm. Most researches are all forces on the segmentation of skull, gray matter, white matter and CSF. Prior to the segmentation of these inner objects in brain, we segmented the scalp and the brain from the MR images. The scalp mask makes us to quickly exclude background pixels with intensities similar those of the skull, while the brain mask obtained from our brain surface. We make use of connected threshold method (CTM) and confidence connected method (CCM). Both of them are two implementations of region growing in Insight Toolkit (ITK). By using these two methods, the results are displayed contrast in the form of 2D and 3D scalp images.

Background: In Korea, few studies clarify insomnia and its association and absenteeism or presenteeism. Therefore, this study aims to examine the association between insomnia and absenteeism/presenteeism using the sixth Korean Working Conditions Survey. Methods: Insomnia was evaluated by the Minimal Insomnia Symptoms Scale (MISS). Absenteeism and presenteeism were assessed by asking if the employee had experienced absence or working despite being ill for the prior 12 months at the point of the survey. Multiple logistic analyses were conducted to explore insomnia and its association with absenteeism and presenteeism. Results: The odds ratios of insomnia for absenteeism and presenteeism were 3.48 (95% confidence interval [CI]: 2.76-4.39) and 3.68 (95% CI: 3.18-4.26) in the fully adjusted model. As the MISS scores increased, absenteeism and presenteeism showed the increasing trend that odd ratios increased accordingly from the first to the fourth quartile. Conclusions: This study observed that insomnia was related to both absenteeism and presenteeism among Korean employees.
