A descriptive correlation study was done to provide a basic data for comprehensive nursing care by analyzing the relationship between spiritual wellbeing, hope and perceived health status of the rural elderly. 130 respondents who lived at their homes and nursing homes for elders in D county. Kyungbuk province were selected and their age was over 60 years old. Paloutzian and Ellison(1982)'s spiritual wellbeing scale. Nowotny(l989)'s hope scale and Northern Illinois University's health self rating scale was used. From September 2nd to September 30th, 2002, ready made questionnaires were handed out by researcher and two well trained nurse research assistants. to those who can fill it out and for those who cannot fill out the questionnaires alone, the researcher and assistants read it and finished by interview. This study used Pearson's correlation coefficient for the hypothetic test and the average point and standard deviation of spiritual wellbeing, hope, and perceived health status were checked. To find out the difference between spiritual wellbeing, hope, and perceived health status by general characteristics ANOVA and Tukey test were used. The results are as follows : 1. The mean score for spiritual wellbeing of the rural elders was $49.94(\pm5.62)$ in a possible range of 20-80. The mean score of religious wellbeing was $25.20(\pm3.91)$ and that of existential wellbeing was $24.74(\pm2.83)$ in a possible range of 10-40. The average point of religious wellbeing was $2.52(\pm0.39)$ points and existential wellbeing was $2.47(\pm0.28)$ points to 4 point full marks. 2. The mean score for hope was $67.68(\pm10.92)$ in a possible range of 29-116. The average point of hope was $2.33(\pm0.38)$ points to 4 point full marks. 3. The mean score for perceived health status was $9.95(\pm2.66)$ in a possible range of 4-14. The average point of perceived health status was $2.15(\pm0.72)$ point to 4 point full marks. 4. In testing the hypothesis concerning the relationship between spiritual wellbeing and hope, there was a statistically positive correlation(r=0.621. p=0.000). 5. In testing the hypothesis concerning the relationship between hope and perceived health status, there was a statistically positive correlation(r=0.305, p=0.000). 6. There were significant differences in spiritual wellbeing according to age(F=5.60, p=0.000), religion(F=11.61. p=0.000), family status(F=2.86, p=0.040) and average monthly pocket money(F=4.32, p=0.015). 7. There were significant differences in hope according to age(F=16.49, p=0.000), religion (F=3.56, p=0.009), educational level(F=8.94, p=0.000), present occupation(t=-3.13, p=0.002), family status(F=5.90, p=0.001) and average monthly pocket money(F=3.41. p=0.036). 8. There were significant differences in perceived health status according to present occupation(t=-2.16, p=0.033) average monthly pocket money(F=4.11, p=0.019). From the above results it can be concluded that: There was a positive correlation between spiritual wellbeing and hope, hope and perceived health status. There was no positive correlation between spiritual wellbeing and perceived health status. For futher study, adequate spiritual wellbeing scale and hope scale for rural elders should be developed and, age and religion factors has to be reconsidered. When the nurse implicate the nursing intervention which can be promote the spiritual wellbeing and hope, rural elder's spiritual wellbeing and hope can be improved and at the same time, their perceived health status also can be improved.

We consider a delayed predator prey model. The local stability and Hopf bifurcation results are stated taking the time delay as a control parameter. We apply multiple scale analysis to analyze the effects of additive white noises near the Hopf bifurcation point at the positive interior equilibrium state. The governing equations for the amplitude of oscillations on a slow time scale are derived. We identify the process of amplitude of oscillations and derive its transient properties. We show that oscillations, which would decay in the deterministic system whenever time delay lies below its critical value, persists for long time under the validity of multiple scale analysis.

This study aims to evaluate healthcare providers' satisfaction and demands pertaining to the collaborative first-stage pilot project between Korean medicine and Western medicine. This survey was conducted via electronic mail among 33 healthcare providers participating in the pilot project. Likert type 5-point scale or Likert type 7-point scale was used to evaluate each item. The response of '${\geq}4$' on the 5-point scale, and '${\geq}5$' on the 7-point scale were analyzed as positive answers. A total of 27 healthcare providers (81.8%) responded, of which 9 were western medical doctors (33.3%) and 18 were Korean medical doctors (66.7%). In respect to satisfaction of the pilot project, 88.9% gave positive responses on improved patients' convenience, 59.3% on treatment efficiency and 55.6% on diagnosis efficiency. In terms of self-evaluation on the pilot project, 70.4% gave positive answers on changes in quality of collaborative treatment, 74.1% on cooperation of results, 63.0% on cooperation of structure and 51.9% on cooperation of process. In terms of demand for collaborative treatment or the pilot project, 'standardized manual' and 'simplification of administrative procedures' showed highest demand, resulting up to 88.9%, followed by 85.2% demanding more public relations and 63.9% demanding enlargement of participating hospitals. This survey revealed that healthcare providers are generally satisfied with patients' convenience and treatment effects. Further studies are needed to develop a standardized manual, simplified administrative procedures, and expanded pilot project contents.

The intention of this study was to investigate relationship of PA (Physician Assistant) nurses' workplace bullying, burnout and emotional intelligence. Research respondents were 150 PA nurses who are working at 19 different hospitals from 5 cities and provinces and the collected data were analyzed with SPSS 21.0 program. This study discovered that 20.7% of PA nurses had experienced workplace bullying and 54.7% had witnessed workplace bullying. The workplace bullying scored 2.14 (on a 4-point scale), emotional intelligence scored 4.88 (on a 7-point scale), and burnout scored 3.22 (on a 7-point scale). As a result of correlation analysis, as workplace bullying was higher, the level of burnout was greater, while as the emotional intelligence was higher, the level of burnout was lower. Thus, there is a need for improvement plan for bullying in workplace to alleviate PA nurses' burnout and strategy to improve emotional intelligence and develop education and program.

Purpose: The purpose of this study was to identify level of recognition of the importance, satisfaction and contribution of APNs' role by physicians, nurses, and advanced practice nurses. Method: Perceived importance and satisfaction were measured with a 23-item questionnaire on APN role with 5 subcategories. APNs' contribution was investigated using a 13-item outcome questionnaire developed by the researchers. Between August 15 and October 31, 2009, the researchers collected data from 68 physicians, 265 nurses, and 23 APNs all working in a single tertiary hospital. Data were analyzed using descriptive statistics, Kruskal-Wallis Test with Bonferroni's Correction and scatter plot. Result: The importance (3.24~3.39, 4 point scale), satisfaction (3.02~3.13, 4 point scale), and contribution of APNs' role (3.39~4.12, 5 point scale) were well recognized by the health care professionals. All the three health care professional groups rated APNs' contribution high in medical service management, continuity of care, patient accessibility, improvement in patient satisfaction, and patient and family education. 'Importance-Satisfaction Analysis' showed that patient data management by APNs needed greater effort. Conclusions: The findings show that the importance, satisfaction, contribution of APNs' role are recognized, and indicate a need for further development of APNs' role through efforts to overcome the gaps identified through this research.

Purpose: The aim of this study was to analyze relationships between perfectionism, burnout, and emotional intelligence in APN and to identify the mediating effect of emotional intelligence on the relationship between perfectionism and burnout. Methods: A structured self-report questionnaire was used to measure perfectionism, burnout, and emotional intelligence. Data were collected from 121 APN working in five advanced general hospitals and two general hospitals. Data were analyzed using descriptive statistics, Independent t-test, One-way ANOVA, Mann-Whitney U test, Pearson correlation and Hierarchical multiple regression with the SPSS/WIN 22.0 program. Results: Mean scores for each variable were: perfectionism 3.57 (on a 5-point scale), burnout 3.32 (on a 7-point scale), and emotional intelligence 5.00 (on a 7-point scale). Self-oriented perfectionism had a positive correlation with burnout, as did socially prescribed perfectionism. Emotional intelligence was a significant variable reducing burnout, as it also had a reverse buffering effect on the relationship between self-oriented perfectionism and burnout. Explanatory power of the final model based on variables was 34%. Conclusion: The results of this study suggest a mediating direction regarding burnout by demonstrating that emotional intelligence plays a direct and reverse buffering role to self-oriented perfectionism, which can be used to reduce burnout in APN.

Before performing an experimental study on the downburst-generated wave, it is necessary to examine the scale effects and corresponding corrections or compensations. Analysis of similarity is conducted to conclude the non-dimensional force ratios that account for the dynamic similarity in the interaction of downburst with wave between the prototype and the scale model, along with the corresponding scale factors. The fractional volume of fluid (VOF) method in association with the impinging jet model is employed to explore the characteristics of the downburst-generated wave numerically, and the validity of the proposed scaling method is verified. The study shows that the location of the maximum radial wind velocity in a downburst-wave field is a little higher than that identified in a downburst over the land, which might be attributed to the presence of the wave which changes the roughness of the underlying surface of the downburst. The impinging airflow would generate a concavity in the free surface of the water around the stagnation point of the downburst, with a diameter of about two times the jet diameter (D_jet). The maximum wave height appears at the location of 1.5D_jet from the stagnation point. Reynolds number has an insignificant influence on the scale effects, in accordance with the numerical investigation of the 30 scale models with the Reynolds number varying from 3.85 × 10⁴ to 7.30 × 10⁹. The ratio of the inertial force of air to the gravitational force of water, which is denoted by G, is found to be the most significant factor that would affect the interaction of downburst with wave. For the correction or compensation of the scale effects, fitting curves for the measures of the downburst-wave field (e.g., wind profile, significant wave height), along with the corresponding equations, are presented as a function of the parameter G.

Objective: This study aimed to develop a parent play interaction observation scale (PPIOS-Toddler) and analyze it in terms of item discrimination, reliability, and validity. Methods: The subjects of the study were 97 toddlers and mothers. This scale consisted of three categories, six domains and 22 items on a 5-point scale. For the item discrimination of the observation scale, an independent standard t-test was conducted to analyze the significant difference in average between the upper and lower groups for each item. The reliability of the observation scale was calculated by Cronbach's α, the intra-item agreement, and the validity was examined through content validity, the correlation between subdomains and total scores, and official validity using PICCOLO. Results: In item discrimination analysis, all items exhibited differences between upper and lower groups. The overall internal agreement for the observation scale was 0.95, with factor-specific internal agreement ranging from 0.83 to 0.95. The observation scale demonstrated notable correlations between total scores and sub-factors (0.45 to 0.93) and significant correlations with PICCOLO total scores (0.66 to 0.86). Conclusion/Implications: The study successfully verified the item discrimination, reliability, and validity of the Parent Play Interaction Observation Scale (PPIOS-Toddler).

Purpose: This study was conducted to compare the level of health concern and the health practice of adult women depending on their experiences with cosmetic tattooing. Methods: The participants were 396 adult women in Jeonnam and Jeonbuk Provinces and G City. Their levels of health concern were measured using the 5-point-5-item scale designed by Kim. For measuring their health practice, the 5-point-12-item scale designed by Kwak was used. Results: The percentage of cosmetic tattooed women was 58.8%. The average score of their health concern was 3.12 and that of their health practice 3.54. As for their levels of health concern, no differences were observed between those with cosmetic tattoo experience and those without. However, the group with cosmetic tattoo experience exhibited a higher level of health practice. Also, most members of the cosmetic tattooed group decided to visit their tattoo shops based on the availability of tattoo shapes or prices rather than considering infection risks. Conclusion: Health education is necessary to increase people's sensitivity to infection. This study shows that urgent attention for the management and regulation of the relevant ministries is required. Also, this study provides foundational information that will serve health education.
