The purpose of this qualitative study was to describe the experience of mothers who have had children with cancer. Participants were seven mothers who had children diagnosed with cancer between 3 to 36 months. Data were gathered through in-depth interviews and analyzed by Colaizzi's phenomenological methodology. Overall, 216 significant statements, 62 formulated statements, 16 themes and five theme clusters were identified. The five theme clusters were 'heartbreaking sadness', 'arduous journey of battling', 'protect my child', 'feeling varying between gratitude and disappointment', and 'suffering and wishing to be with family'. Mothers who have had children with pediatric cancer receiving chemotherapy have experienced strong emotional fluctuations as well as hope as they cope with their ill child. However, they try to become strong women and embrace their family to cope with their situation. The results of this study will support for health professionals to understand mothers who have had children with cancer and to consider the supportive nursing care in considering mothers' emotional fluctuation.

The standard volume ray-tracing, optimized with octree, needs to repeatedly traverse hierarchical structures for each ray that often leads to redundant computations. It also employs the expensive 3D interpolation for producing high quality images. In this paper, we present a new ray-casting method that efficiently computes shaded colors and opacities at resampling points by traversing octree only once. This method traverses volume data in object-order, finds resampling points on slices incrementally, and performs resampling based on 2D interpolation. While the early ray-termination, which is one of the most effective optimization techniques, is not easily combined with object-order methods, we solved this problem using a dynamic data structure in image space. Considering that our new method is easy to implement, and need little additional memory, it will be used as very effective volume method that fills the performance gap between ray-casting and shear-warping.

Staphylococcus aureus is found on the skin of $78{\sim}100%$ of children and adults with atopic dermatitis (AD) but only on the skin of $2{\sim}25%$ of healthy subjects. It is known that S. aureus and their endotoxins as superantigen have important roles in the exacerbation and prolongation of AD. This study was carried out for the detection of S. aureus in the skin of AD, age, sex, outbreak age of AD, treatment duration, aggravation season, and the relation of ooze and S. aureus. Most patients (84%) with AD show colonization of the skin with S. aureus and there is a correlation between the degree of colonization and the serous exudate. It seems likely that the inhibition of S. aureus is associated with improvement in the skin of AD patients.

Purpose: The purpose of this study was to examine posttraumatic growth (PTG) in family caregivers of patients with cancer. Methods: Participants included 201 family caregivers of cancer patients who are treated at outpatient clinics and oncology wards of a university hospital and two general hospitals in Busan, Korea. The study instrument was the Korean version of the posttraumatic growth inventory (K-PTGI). Data were analyzed with descriptive statistics, t test, one-way ANOVA and Scheffe's test using the SPSS 21 for Windows. Results: The mean score of PTG was 3.10. The factor with the highest score was "Changes to self-perception" (3.15), while the one with the lowest was "Increase in spiritual interest" (2.88). There were significant differences in PTG, depending on age, religion, importance of religious life and perceived level of daily difficulties. Conclusion: Family caregivers also experience PTG when their loved ones are diagnosed with cancer. According to these findings, it is necessary to develop a spiritual nursing program to help family caregivers growth from the experience of attending patients with cancer.

In order to establish effective fishing ground environment equipment and artificial reef in coastal area, the methodology to select the most suitable area for artificial reef should be applied after analyzing the correlation between fishing ground environment and ocean environment. In this paper, thematic maps were prepared by using satellite remote sensing and GIS for the sea surface temperature, chlorophyll, transparency, the depth of sea water and the condition of submarine geologic which are considered as the most elements when selecting suitable area for artificial reef in Tong-Yong bay. Then, the most suitable area for artificial reef was selected by giving weight score depending on the suitable condition of this area and analyzing spatial data. The results showed it makes possible for this methodology, which selects the suitable area for artificial reef using satellite remote sensing and GIS, to manage the institution of artificial reef more entirely and efficiently through analyzing and visualizing.

Recently, the number of elderly people residing in nursing homes has increased rapidly due to the increase in the elderly population and the introduction of long-term care insurance. These long-term care patients suffer from chronic illnesses and dementia, and thus suffer from inconveniences or lack of cognitive ability. Thus, psychological and emotional support is urgent because they are depressed away from their families. Therefore, in this paper, we aim to provide a virtual experience of overseas trips by using VR and Photon networks for elderly patients with mobility difficulties. Existing VR-based travel experience service is doing alone, but the proposed contents can enjoy the scenery together with the view of the family member as well as the conversation during the travel experience. It is expected that the elderly patients with long - term care will be able to restore their psychological stability and improve their willingness to heal and improve their quality of life from the proposed application.

This study was attempted to identify the media preferences and the reasons of cancer patients. The data collection was conducted on 76 people. and they are 6 men, 70 women with 38 breast cancer patients, and 38 patients with other cancers. For measuring tools, self-written questionnaires and Mandala paintings were used for single-time art therapy. The data analysis compared the results of technical statistics, independence verification and chi verification using the SPSS WIN ver.25.0 with the Mandala painting. There were no significant differences in media preference by age and duration of the disease, and there were significant differences in media preference by disease. In the Mandala painting, the characteristics of the medium and the factors of specific disease showed that there were reasons and effects of preference media choice. This study is meaningful in that it concentrated on the art therapy access and support in terms of the cancer outpatients, which have been concentrated on inpatients so that they shed light to the support and intervention needed by the outpatients, and can be used as basic data for the development of art therapy programs to help stabilize the mind of cancer patients in the future.

Mode choice Analysis is essential analysis stage in transportation demand forecasting process. Therefore, methods for calibration and forecasting of mode choice model in aspect of practical view need to be discussed in depth. Since 1980s, choice models, especially Logit model, are spread widely and rapidly over academic area, research institutes and consulting firms in Korea like other developed countries in the world. However, the process of calibration and parameter estimation for practical application was not clearly explained in previous papers and reports. This study tried to explain clearly the calibration process of mode choice step by step and suggested a forecasting mode choice model that can be applicable in real policy analysis by using household survey data of Pusan metropolitan are. The study also suggested a way of estimating attributes which was not observed during the household survey commonly such as travel time and cost of unchosen alternative modes. The study summarized the statistical results of model specification for four different Logit models as a process to upgrade model capability of explanation for real traveler's choice behaviors. By using the analysis results, it also calculated the value of travel time and compared them with the values of other previous studies to test reliability of the estimated model.
