Purpose: This study was aimed to construct an algorithm of dyspnea emergency care and develop a simulation scenario for emergency care of dyspnea based on the algorithm. Methods: The first stage of this methodological study was to construct a preliminary algorithm based on a literature review, and content and clinical validity were established. Reflecting the result of content and clinical validity for this preliminary algorithm, simulation scenario was developed based on the modified Bay Area Simulation Collaborative scenario template. The content validity of this scenario was established, and clinical applicability was tested by applying this scenario to nurses. Results: The final simulation scenario of emergency care of dyspnea consisted of scenario overview, curricular integrity, and scenario script. The scenario was proceeded on 7 phases of the algorithm as follows; initial assessment, immediate emergency care, reassessment of dyspnea, monitoring respiratory failure, checking pulse if respiratory failure occurs, decision making on cardiopulmonary resuscitation or intubation, determining a differential diagnosis according to origin of dyspnea. Conclusion: The simulation scenario of emergency care of dyspnea developed in this study may provide a strategy of simulation education for emergency care of dyspnea for nurses.

Purpose: To develop Pregnancy Risk symptom Perception Scale (PRPS) and evaluate its validity and reliability. Methods: A preliminary 30-item version of PRPS was developed through literature review, in-depth interview, and Content Validity. Each item was scored on a four-point Likert scale. The preliminary scale was developed based on 301 pregnant women who visited a hospital. Date were analyzed using item analysis, factor analysis, confirmatory factor analysis, Pearson's correlation coefficients, and Cronbach's ${\alpha}$ (0.90 for total item, 0.80 to 0.88 for factors). Results: The PRPS consisted of 27 items. Three factors (physical, environmental, and emotional factors) explained 55% of the total variance. Cronbach's Criterion validity was supported by comparison with the Perception of Pregnancy Risk Questionnaire (r=0.34). In reliability test, the reliability coefficient of pregnancy risk symptom perception was high at 0.90. Conclusion: These results suggest that the pregnancy risk symptom perception scale developed in this study comprises items that can assess the level of pregnant women's pregnancy risk symptom perception in Korea. Its validity and reliability were proven. PRPS can be utilized to measure pregnant women's risk symptom perception during pregnancy. PRPS will contribute to the development of systematic prenatal care and effective risk management.

End-of-life care competencies have been perceived as important and essential, so it has been suggested that end-of-life care be studied in undergraduate medical education. However, end-of-life care curriculum has mostly focused on acquisition of knowledge and skills rather than attitudes. Therefore, we aimed to explore whether education about death affects medical students' attitudes towards care for dying patients and perception of death anxiety, meaning in life, and self-esteem. A total of 15 first- or second-year medical students were surveyed with questionnaires before and after completing a 6-week death education course. Paired data analysis showed that participants' attitudes towards caring for terminally ill patients and their caregivers improved significantly (t=-2.84, p=0.013) with an effect size of 0.73. In contrast, no significant changes were found in death anxiety, meaning in life, or self-esteem. All participants agreed that formal teaching about death and dying must be encouraged in medical schools. Our results suggest that death education may positively influence attitudes towards end-of-life care. Although replication with larger samples is necessary, this preliminary finding may support the importance of developmentally appropriate end-of-life care education in medical schools.

Purpose: This study was designed to develop and test the Hope Scale for Korean cancer patients. Methods: The process for the development of the Hope Test was a selection of initial items drawn from a literature review and in-depth interviews. The selected items were assessed for content validity by experts. The Hope Scale was comprised of five factors and 30 preliminary items. The preliminary Hope Scale for Korean Cancer Patients (HS_KCP) was administered to 259 cancer patients from one university hospital and one cancer hospital in Busan. Data were analyzed using item analysis, factor analysis, Pearson correlation coefficients, and Cronbach's ${\alpha}$. Results: Eighteen items were selected for the final scale. Five factors (inner sense of control, trust and expectation for recovery of disease, interconnection, spirituality, emotional despair) evolved from the factor analysis, which explained 63.3% of the total variance. The convergent & discriminent validity was r=.83 (p<.001), r=-73 (p<.001). The internal consistency, Cronbach's ${\alpha}$ was .88 and reliability of the subscales ranged from .54 to .85. Conclusion: The Hope Scale for Korean cancer patients demonstrated acceptable validity and reliability. It can be used to assess the hope of cancer patients and is feasible within a clinical setting.

Objective: The objective was to extract a preliminary performance measurement indicators of nursing organizations in hospitals using the BSC(Balanced Score Card) developed by Kaplan and Norton, and to analyze the content validity and evaluation methods of the performance measurement indicators with actual nurses in the nursing organization as participants in the study. Methods: The preliminary performance measurement indicators was created through a literature review and had the content validity by a professional. This survey was sent via post to 316 nurse managers and nurses with more than 5 years of experience in seven secondary and tertiary hospitals in the Seoul Gyonggi district. The completed questionnaires were returned by mail. Results: Fourteen indicators for finances, 16 for customer services, 27 for internal business processes, and 13 for learning and growth were selected. Conclusion: Amidst a rapidly changing medical environment, a first step was taken towards developing a performance measurement from various perspectives for nursing organizations in hospitals from various perspectives, rather than just one or a past-oriented perspective. However, as the most important thing is to actually use these indicators, continuous interest in publicity and education must be developed.

Purpose: The purpose of this study was to develop a measurement tool of nurse's turnover intention. Methods: Data were collected from questionnaires completed by 678 nurses who worked in 3 university hospitals in South Korea and analyzed using the SPSS 18.0 and AMOS 18 programs. Thirty-seven preliminary items were selected from 161 basic items extracted via a literature review and in depth interviews with 6 hospital nurses. Three steps with factor analysis were undertaken to verify the reliability and validity of the preliminary instruments. Finally, confirmative factor analysis was carried out. Results: As a result of the analysis, 3 factors including 10 items were selected. Cronbach's Alpha for the 10 items was .83, for job satisfaction (4 items), .78, for interpersonal relationships (3 items), .80, and for work performance (3 items), .74, which was stable. Conclusion: This study is meaningful because through it a scale reflecting Korean culture was developed to measure turnover intention in nurses. Further studies that test the psychometrics of this scale in more diverse samples are warranted.

As online shopping is expanding rapidly, the damages undergone by consumers are also dramatically increasing. This research mainly focused on the damages experienced through Internet shopping. The purpose of this study was to develop a standardized scale to measure damages sustained through an Internet shopping mall. A preliminary 35-item scale was developed through a literature review, and 1,230 consumers responded to an online survey using the preliminary scale. This research was supported by the surveys conducted on consumers who had previously shopped at an Internet fashion mall. This research was conducted with the intention of not only supplying academic data on the damage sustained by consumers, but also understanding the consumers' basic behavior patterns. Then a series of tests, such as test-retest, item-to-total correlation, Cron bach's reliability coefficient and factor analysis, were conducted using the survey data and a final scale with 26-items was constructed in the end. The damage sustained in Internet shopping malls scale for consumers consisted of three factors: 1. Trouble with safety 2. Trouble with payment and delivery; and 3. Trouble with after-sales services.

Purpose: The purpose of this study was to develop and validate a Nurse's Character Scale for Care in Clinical settings (NCS_C). Methods: The NCS_C was developed and validated as follows: Item generation, preliminary test of questionnaire, and tests of validity and reliability. One hundred and thirty six preliminary items were developed through a literature review and in-depth interviews by 10 nurse-experts and five patients. The content validity of the items was verified through an evaluation by five nurses and seven professors in the fields of Korean literature, pedagogy and nursing. Finally, 53 items were confirmed through item analysis, factor analysis and validity tests including convergent, discriminant and concurrent validities. Data were analyzed using factor analysis, Pearson correlation coefficients, and Cronbach's alpha. Results: Thirteen factors evolved from the factor analysis, which explained 63.1% of the total variance. The factors referred to the union of two dimensions: the professional dimension and the interpersonal dimension. The internal consistency, Cronbach's alpha, was .95, and reliability of the subscales ranged from .58 to .87. Conclusion: The results of this study suggest that the NCS_C is a reliable and valid primary scale to measure nurses' or students' character level for better care in clinical settings.

Purpose: The purpose of this study was to develop a scale to evaluate posttraumatic growth in patients with cancer and to examine the validity and reliability of the scale. Methods: A literature review, semi-structured patient interviews and an expert panel consultation produced a 27 preliminary item questionnaire. Participants were 150 cancer patients recruited to test the reliability and validity of the preliminary scale. Data were analyzed using item analysis, exploratory factor analysis, convergent validity and internal consistency. Results: Item reduction and exploratory factor analysis led to 23 items, grouped into five subscales which were labelled new possibilities (6 items), coping skills (5 items), preciousness of life (5 items), relating to others (4 items), and personal strength (3 items). Convergent validity was evaluated by total correlation with the Functional Assessment of Cancer Therapy-General (r=.45, p<.001). The final scale demonstrated satisfactory internal consistency (Cronbach's ${\alpha}$ =.94). Conclusion: Findings from this study indicate that the Cancer-Specific Posttraumatic Growth Inventory has validity and reliability and is considered to be appropriate for assessing posttraumatic growth in patients with cancer.
