Purpose: The purpose of this study was to develop an instrument to assess nursing professional pride. Methods: Fifty-six preliminary items were identified through literature review and focus group interview of nurses working in a hospital. Of these, 45 preliminary instruments were completed over 0.80 of content validity index. To verify the reliability and validity of the preliminary instrument, data were collected from 294 nurses. The data were analyzed using factor analysis and multidimensional scaling analysis. Results: From the factor analysis, 27 significant items were divided into 5 subscales. These subscales were as follows: feeling of vocation, role satisfaction, role of problem solver, self-achievement, and willingness to stay. The nursing professional pride also established criterion-related validity, discriminant validity, and group validity. Cronbach's α of the instrument was .92, and the subscales ranged from .74 to .85. Conclusion: The developed scale for nursing professional pride shows validity and reliability. The significance of this study is the development of an instrument capable of measuring nursing professional pride. To verify the relevance of this instrument, conducting comparative studies is suggested.

In general, cancer pain is neither fully recognized nor adequately treated. The inadequate pain control is due to failure of accurate assessment of cancer pain. This study was aimed to understand various characters of cancer pain and investigate available assessment scales which have been designed for, or frequently used with people with cancer pain. A total of 23 articles were selected from two different databases. The selected articles were analyzed according to three aspects of initial assessment, patient self-report and assessment of the outcomes of pain management. The characters of cancer pain is complex and includes physical, psychosocial, and spiritual dimension. Also, subjective pain can be classified into at least four specific factors, such as pain intensity, pain affect, pain relief, and pain quality. Based on various classification, the pain assessment scales can be divided into unidimensional or multidimensional. Among the more commonly used clinical tools are numeric rating scales, verbal rating scales, visual analog scales, and picture scales. Above all, in order to assess cancer pain objectively, the clinician must select appropriate assessment instruments which reflect pain definition and clinical purpose.

With the continuous development of LBS (Location Based Service) applications, privacy protection has become an urgent problem to be solved. Differential privacy technology is based on strict mathematical theory that provides strong privacy guarantees where it supposes that the attacker has the worst-case background knowledge and that knowledge has been applied to different research directions such as data query, release, and mining. The difficulty of this research is how to ensure data availability while protecting privacy. Spatial multidimensional data are usually released by partitioning the domain into disjointed subsets, then generating a hierarchical index. The traditional data-dependent partition methods need to allocate a part of the privacy budgets for the partitioning process and split the budget among all the steps, which is inefficient. To address such issues, a novel two-step partition algorithm is proposed. First, we partition the original dataset into fixed grids, inject noise and synthesize a dataset according to the noisy count. Second, we perform IH-Tree (Improved H-Tree) partition on the synthetic dataset and use the resulting partition keys to split the original dataset. The algorithm can save the privacy budget allocated to the partitioning process and obtain a more accurate release. The algorithm has been tested on three real-world datasets and compares the accuracy with the state-of-the-art algorithms. The experimental results show that the relative errors of the range query are considerably reduced, especially on the large scale dataset.

Purpose: The purpose of this study was to examine the relationship between social support (family, healthcare provider, friends/peer), treatment belief, hope, and health status in patients on hemodialysis, and to identify direct and indirect effects of the variables on patients' health status. Methods: The self-regulation model was used to establish a path model. Data were collected from 240 patients. Multidimensional Scale of Perceived Social Support, Revised Illness Perception Questionnaire, Herth Hope Index, and Medical Outcomes Study Short Form-12 were used. Data were analyzed using the SPSS and AMOS programs. Results: The model was supported by fit statistics ($x^2=3.33$, p=.343, GFI .995, RMSEA .021, AGFI .968, NFI .986, CFI .999, TLI .993). Family and friends/peer support showed a significant direct influence on hope, while healthcare provider support directly influenced treatment belief. Social support, treatment belief, and hope directly and indirectly influenced health status, explaining 28.7% of the variance. Conclusion: These results show mechanisms underlying connections between social support and health status by demonstrating impact of social support and showing treatment belief and hope as mediators between social context and outcomes. To promote health of patients on hemodialysis, it is necessary for patient, family, healthcare professional, and friends to collaborate.

Purpose: The purpose of this study was to identify the conceptual structure of stressors experienced by nursing students during clinical practice. Methods: Ten men and 10 women nursing college students were interviewed. The results were 208 ideas. By synthesizing and editing these ideas, the final statement was trimmed down to 39 questions. The next step was to have the participants classify these 39 final questions. They were asked to rate stress scores using a five-point scale. Through multidimensional scaling analysis and hierarchical cluster analysis yielded dimensions and clusters. Results: Results of the study showed 2 dimensions which were classified as 'interpersonal relationship-practice system' and 'identity-practice environment'. It also yielded 8 clusters which were classified as 'role confusion', 'gender discrimination', 'attitudes of medical personnel and patients', 'comparison between fellow students', 'difference between theory and practice', 'disestablishing the role of practice guide', 'interference with training', and 'problems of the practice environment'. Further, stress factors and stress levels were differentiated depending on the gender of the student. Conclusion: The results of the study indicate that educators who are developing clinical practice programs and clinical practitioners should consider stressors during clinical practice and the educational implications to nursing students.

Purpose: This study was done to identify factors associated with fatigue in pediatric patients with cancer in order to develop nursing interventions for this population. Methods: The participants were 95 pediatric cancer patients admitted to a university medical center in Seoul, Korea, and 95 parents. The $PedsQL^{TM}$, Multidimensional Fatigue Scale developed by Varni (2002) was used to measure fatigue. Data were analyzed with the SAS program and t-test, analysis of variance (ANOVA), Pearson correlation coefficients, and multiple regression were used to identify the association of factors with fatigue. Results: The mean score for fatigue was 30.42 in the pediatric cancer patients and 34.77 in the parents. Fatigue was higher in patients living with a single parent, in patients whose father had a lower education and those patients with a fever. Pain, frequency and intensity of nausea and vomiting, depression, anxiety, and disruption of usual activity were positively associated with fatigue. The predictive factors for fatigue were disruption of usual activity, depression and living with or without parents. Conclusion: Pediatric patients with cancer experienced fatigue during their diagnosis and treatment. Of the multiple factors associated with fatigue, the association between disruption of usual activity and fatigue was the highest indicating a need to be concerned with this factor when providing interventions to alleviate fatigue.

Purpose: The purpose of this study was to compare health locus of control with health-promoting behaviors according to elementary school children's degree of obesity, and to analyze correlations between two variables. Methods: Three hundreds and sixty three elementary school children were participated from three elementary schools in Seoul. Multidimensional Health Locus of Control (HLOC) scale and Health Promoting Lifestyle Profile (HPLP) were used. Results: Obese children was 16.8% of all research subjects. Internal HLOC in over weight group was higher than normal weight group (F=3.611, p=.014). Chance HLOC in under weight group was higher than other groups (F=3.553, p=.015). External HLOC in over weight and obesity group was higher than normal weight group (F=3.553, p=.015). Correlations between HLOC in internal and external and health-promoting behaviors were significant (r=.347, p<001; r=.207, p<001). Also, children who did not have siblings and have obese parents showed higher rate of obesity, and lack of sleeping time tend to be related to obesity. Conclusion: External HLOC of obesity children is higher than that of normal weight children. Meanwhile, obese children with higher internal HLOC were good at doing health-promoting behaviors. Therefore, if obese children are trained for internal health control, it can lead to their health-promoting behaviors.

Objective: Objective of this study was to investigate community pharmacy-based pharmaceutical care accessibility in Korea. Survey on the current pharmaceutical care service provision was performed by PM2000 XE, a real-time pharmacy manager program, operated by Korea Pharmaceutical Information Center beginning November 4, 2013 until December 6, 2013 towards all community pharmacies throughout the nation which use the program. Method: The survey questionnaire consisted of four sections: pharmacy type, time-based accessibility, item-based accessibility, and spatial accessibility for non-prescription drugs. Results: Number of pharmacy responded to the survey was 331, and size of the responding pharmacy was mostly medium-scale (66.47%) with 30-99 prescription fillings a day. Proportion of pharmacy with opening hour of 12 hours or longer was only 53.77% and it was less than 25% during saturdays and holidays. Item-based accessibility was generally acceptable for prescription and non-prescription drugs, medical devices, and health supplements. However, spatial accessibility for non-prescription drugs was problematic because only one quarter of the drugs was displayed over the counter, and most of the drugs were behind the counter so that customers could not reach out. Conclusion: Based on the survey result, current situation for accessibility of pharmaceutical care service in Korea is concluded inadequate and therefore needs multidimensional efforts to improve accessibility of the service at national level such as Korea Pharmaceutical Association and Ministry of Health and Welfare.

Edward Hopper is one of the great American artists in the 20th Century. In the field of art, it seems that his paintings are thoroughly analyzed In terms of human alienation and emotional aspects in various ways. However, in his numerous paintings, highly interesting spatial aspects can be found. Purpose of this study is to analyze some of his painting by the spatially analytical tools to examine how his space is experienced. The tools are: relationship between each space, relationship between light and space, and geometrical composition. Among many paintings by Hopper, four of the works that depicted interior spaces are selected and further case-studied in detail: ${\ulcorner}$Rooms by the Sea${\lrcorner}$ (1951), ${\ulcorner}$Sun in an Empty Room${\lrcorner}$ (1963), ${\ulcorner}$New York Movie${\lrcorner}$ (1939) and ${\ulcorner}$Automat${\lrcorner}$ (1927). An Environmental Simulation with scale models was used to examine the relation between light and space. After the research, some unique characteristics of his space were found. Even though his paintings seem to represent the everyday spaces, there are fascinating hidden structure to make people experience in a specific way that Hopper created. Spaces In his paintings do not communicate with each other but are constantly interrupted by the element of time. The mundane everyday world is rediscovered and recreated through these multidimensional and heterogeneous space.

Conventional integral effect test facilities were constructed to enable the precise observation of thermal-hydraulic phenomena and reactor behaviors under postulated accident conditions to prove reactor safety. Although these facilities improved the understanding of thermal-hydraulic phenomena and reactor safety, applications of new technologies and their performance tests have been limited owing to the cost and large scale of the facilities. Various nuclear technologies converging 4th industrial revolution technologies such as artificial intelligence, drone, and 3D printing, are being developed to improve plant management strategies. Additionally, new conceptual passive safety systems are being developed to enhance reactor safety. A new integral effect test facility having a noticeable scaling ratio, i.e., the (UNIST reactor innovation loop (URI-LO), is designed and constructed to improve the technical quality of these technologies by performance and feasibility tests. In particular, the URI-LO, which is constructed using a transparent material, enables better visualization and provides physical insights on multidimensional phenomena inside the reactor system. The facility design based on three-level approach is qualitatively validated with preliminary analyses, and its functionality as a test facility is confirmed through a series of experiments. The design feature, design validation, functionality test, and future utilization of the URI-LO are introduced.
