Purpose: Smartphones, which are widely used worldwide to detect acceleration and position, have been used in the area of rehabilitation medicine in recent clinical research studies and tests. The aim of the present study was to determine the feasibility of using a smartphone application based on center of movement (COM) displacement to measure gait parameters in stroke patients in the clinical field of rehabilitation medicine. Methods: The study consisted of 30 stroke patients. The COM was measured using a smartphone application, Gait Analysis Pro, during a 6-m walk. Each patient performed three 6-m walking trials, and the smartphone application measured gait duration, gait speed, step length, cadence, and vertical and lateral displacement of the COM. The Kolmogorov-Smirnov test was conducted to determine the normality in gait parameters, and a repeated one-way analysis of variance (ANOVA) was performed to determine the consistency among the three trials. A p value of 0.05 was considered statistically significant in all the tests. Results: In all the measured parameters, the smartphone application showed a normal distribution, as shown by the results of the Kolmogorov-Smirnov test. There were no significant differences among the three repetitive walking trials. Conclusion: These results suggest that the smartphone application can be used for evaluating gait in stroke patients, as well as in healthy adults. However, prior to using the smartphone application in the clinical field, further research involving three-dimensional gait analysis is needed to enhance the confidence level of the findings.

Purpose: This study was done to examine changes towards positive ethics in registered nurses working in hospitals who took part in performing 'theatre of situations' in terms of issues of nursing ethics. Methods: This research was conducted with one-group pretest-posttest design. The sample, 232 registered nurses, voluntarily participated in a contest of 'Theatre of Situations' with themes of nursing ethics hosted by Hospital Nurses Association of Korea on September 8, 2011. For this contest, eight nursing situational scenario regarding ethical issues or dilemma were created. The theatre of situation was performed by volunteer nurses over a period of 160 minutes. Data were collected before and after the performance using 10 items to measure Positive Ethics. Item internal consistency had a Cronbach's alpha in this study of .716. Results: Before the theatre of situations was performed, the mean (${\pm}$standard deviation) level of positive ethics was 2.34 (${\pm}.37$). For the nurses who participated, there was a significant increase in the degree of positive ethics after the theatre of situations ($2.62{\pm}.36$, p<.001). Conclusion: This result implies that indirect experiences such as 'theatre of situations' in terms of ethical issues, created as well as performed, is effective for registered nurses in changing their ethical perspective positively and in realizing ethical ideals.

Objective : Cognitive fusion, or believability, in acceptance and commitment therapy (ACT), refers to the tendency to become entangled in one's thoughts or feelings. It is an important factor in the development and maintenance of anxiety disorders. However, there is a lack of validated self-report measures for cognitive fusion and defusion, particularly for individuals with anxiety. To address this gap, this study aimed to evaluate the Korean Version of Believability of Anxious Feelings and Thoughts Questionnaire (K-BAFT). Methods : A total of 608 university students and 85 patients with obsessive-compulsive disorder (OCD) took part in this study. They were asked to complete various psychological measures, including the K-BAFT, other measures of ACT processes, and symptom scales. The researchers then analyzed the psychometric characteristics of the K-BAFT. Results : The results of the exploratory and confirmatory factor analyses indicated that the three-factor structure of the K-BAFT, which was reported in the original study, was also found in the university sample. Additionally, both the student and the OCD group demonstrated strong internal consistency (α=0.86 and 0.91, respectively). In the university sample, the K-BAFT showed a strong correlation with the Cognitive Fusion Questionnaire (r_s=0.53, p<0.001). However, it had a weak correlation with symptoms scales for depression, anxiety, and stress (all r_s<0.32). Furthermore, the OCD group had higher scores on the K-BAFT compared to the university sample. Conclusion : K-BAFT is considered to be a reliable and valid self-report tool for measuring cognitive fusion with anxious thoughts and feelings.

The purpose of the study was to test the reliability and validity of the Korean version of Children's Health Locus of Control Scale (CHLC), an instrument designed to measure health locus of control in children aged 7 to 12. The scale was administered to 467 children in grades 4 to 6, enrolled in 2 elementary schools located in city. The mean age of the subject was 10.03 (SD=1.33). The findings were as follows: 1. Cronbach alpha coefficient for internal consistency was .69 for the total, and .67, .65, and .56 on the respective subscales. 2. Construct validity was supported through factorial isolation of three theory consistent subscales : internal, chance, and powerful others. Two items did not fit well with the originally developed subscale. The total percent of varience explained by 3 factors was 34.5%. The result of the factor analysis according to Kaiser's criterion revealed that the scale was consisted of 5 factors. But, The items of the subscales were rather inconsistent with the dimensions of the locus of control concept. 3. There were significant differences according to parent's educational level and occupation, and birth order on the scores of the CHLC. There were no significant differences according to grade level and sex. 4. The score of the CHLC was significantly correlated with the self concept of the children(r=.14, p<.001). The result indicated that the Korean version of Children's Health Locus of Control Scale was valid and reliable in measuring health locus of control concept in children, even though luther research is required to reconfirm and increase the reliability of the instrument. CHLC could be used for study explaining the health related behavior of the children and research project related to health education program.

The purpose of this research was to identify the effect of human potential seminars on the perceived stigma of adults with epilepsy. The research employed a quasi experimental design and unequivalent control group pre-post design. The test was conducted on 15 adults with epilepsy attending one psychiartric out-patient clinic in Masan City, Korea. The stigma questionnaire was used as a pre-test to these patients. HPS was done ten times for five weeks from May 6, to July 26, 1996. The stigma questionnaire was again given, but this time as a post test. The control group of 14 adults with epilepsy were receiving medication at the same clinic. The human potential seminars were structured by McHolland(1972) and translated by Lee, Hae Seung(1990). The stigma research tool was modified and revised to be appropriate to Korean culture. It consisted of 15 sentences. The internal consistency was 0.92 with Cronbach's α. Research results are as follows. 1) To determine the homogenity of the experimental and control groups, the pre-stigma results were used and democratic-sociologic characteristics, job characteristics and disease related variables were compared. There was no significant difference between the two groups. 2) To identify the relationship between stigma and patient characteristics a pre-test was done. The study used both Mann-Whitney U-test and ANOVA test for statistical analysis. The variables related to stigma were the reason of unemployment and age at onset of epilepsy. 3) The test results of the effect of the human potential seminars on stigma in the patients with epilepsy, showed that stigma in the experimental group was lower than in the control group. The statistical method used to determine the difference between pre and post stigma results was the Wilcoxon signed rank test. The test results were statistically significant at the one percent level. 4) As a follow-up evaluation ten more patients(66.7% of the total) were additionally tested. In order to investigate if the stigmas were different between the pre, post and follow-up, Repeated measure ANOVA was used. The test results showed that the stigma scores were statistically different between the three groups at the one percent level(F=10.06, d.f.=2, p=0.00).

The purpose of this study was to develop a tool to assess the powerlessness and to measure the powerlessness of elderly. From the result of pre-test, twenty seven items were finally selected to survey the elderly's powerlessness. The questionnaires on the elderly's powerlessness were drafted so that such tool may be evaluated in accordance with the four point Likert Scale. The number of subjects is 1,150 with ages of 60 years or more and who live in a large city, a small and middle-sized city and a rural area. The subjects of the test and retest were 85 elderlies. Collected data were analyzed by utilizing SAS program with Cronbach's $\alpha$ and Pearson's correlation, factor analysis method and known group techniques, descriptive statics, t-test and ANOVA. The results from this study were summarized below:1. When the factor analysis method was applied for validity, the tool for powerlessness of elderly was separated into 5 factors: loss of self-confidence to deal with physical, emotional, social aspects of life; expulsion by others from meaningful human relate; perception that life is meaningless and time passes quickly; falling behind young people; being rejected by other people, having no influence on others. An application of the known group technique showed a significant difference with the result of the degree of elderly's powerlessness tools developed by the two groups, with illness and without. 2. In testing reliability, it was found that coefficient of test-retest was .9435(P<.0001) when the test-retest method was used as a test of stability, and that the alpha coefficient of internal consistency was .9141 over all items within the tool of elderly's powerlessness 3. In powerlessness of elderly, total mean is 2.8493. And in factor of powerlessness, the highest factor is falling behind young people (M=3.1713), the lowest factor is loss of self- confidence to deal with physical, emotional, social aspects of life(M=2.6080). 4. The results from the test for the degree of powerlessness, according to the subject's demographic variables, showed that there were significant differences between age, sex, marital status, educational level, religion, possession of house, job, monthly pocket money, health status, illness and a place of residence.

Purpose: This study aimed to evaluate the validity and reliability of the Korean version of Menopause-Specific Quality of Life (MENQOL). Methods: The MENQOL was translated into Korean according to algorithm of linguistic validation process. A total of 308 menopausal women were recruited and assessed using the Korean version of MENQOL (MENQOL-K), the World Health Organization Quality of Life Brief Version (WHOQOL-BREF), and Center for Epidemiological Studies Depression Scale (CES-D-K). In estimating reliability, internal consistency reliability coefficients were calculated. Validity was evaluated through criterion validity and construct validity with confirmatory factor analyses using SPSS 23.0 and AMOS 25.0 software. Results: In item analyses, the "increased facial hair" symptom was excluded because of the low contribution of MENQOL-K. The confirmatory factor analysis supported good fit and reliable scores for MENQOL-K model, and the four-factor structure was validated (χ²=553.28, p<.001, NC=1.84, RMSEA=.05, AGIF=.85, AIC=765.28). The MENQOL-K consists of 28 items in 4 domains, including vasomotor (3 items), psychosocial (7 items), physical (15 items), and sexual subscales (3 items). There was an acceptable criterion validity with moderately significant correlation between MENQOL-K and WHOQOL-BREF. The Cronbach's α for the 4 subsacles ranged from .80 to .93. Conclusion: The MENQOL-K is a valid and reliable scale to measure condition-specific quality of life for perimenopausal and postmenopausal women. It can be used to assess the impact of menopausal symptoms on the quality of life of Korean women in clinical trials.

Objective : Existing depression rating scales do not fully reflect depressed patients' perspective of remission, which goes beyond symptom resolution. The Remission from Depression Questionnaire (RDQ) captures a broader array of domains, and the present study examines the reliability and validity of the Korean Version of the RDQ (K-RDQ). Methods : The test-retest reliability of the K-RDQ was studied in 60 depressed patients and 30 normal subjects working at a university hospital. Subjects were evaluated at baseline and again 1-2 weeks later. The validity of the K-RDQ was studied in 200 depressed patients who were rated on the 17-item HDRS and the CGI-S ; each patient also completed the QIDS-SR, STAI-S, GHQ/QL-12, and SDS. Results : The K-RDQ demonstrated excellent internal consistency, with a Cronbach's ${\alpha}$ of 0.965 for the total scale and above 0.80 for each of the 7 subscales. The test-retest reliability of the total scale was 0.951. Mean K-RDQ scores ($45.79{\pm}18.65$) of the depressed patients were significantly higher than those ($15.87{\pm}10.60$) of the mentally healthy subjects (t=12.8, p<0.001). Five factors from the K-RDQ were extracted by principal axis factoring with equimax rotation. Conclusion : These results indicate that the K-RDQ is a reliable and valid measure that evaluates multiple domains that depressed patients consider important in determining remission. Thus, the K-RDQ maybe considered an appropriate tool for use in the clinical setting.

Purpose: The purpose of this study was to develop a scale to measure person-centered critical care nursing and verify its reliability and validity. Methods: A total of 38 preliminary items on person-centered critical care nursing were selected using content validity analysis of and expert opinion on 72 candidate items derived through literature review and qualitative interviews. We conducted a questionnaire survey with 477 nurses who worked in intensive care units. The collected data were analyzed using exploratory factor analysis (EFA) and confirmative factor analysis (CFA) with SPSS and AMOS 24.0 program. Results: EFA was performed with principal axis factor analysis and Varimax rotation. The 15 items in 4 factors that accounted for 50.8% of the total variance were identified by deleting the items that were not meet the condition that the commonality should be .30 or more and the factor loading over .40. We named the factors as compassion, individuality, respect, and comfort, respectively. The correlation coefficient between this scale and the Caring Perception Scale was r=.57 (p<.001), which determined concurrent validity. The item-total correlation values ranged from .39 to .63, and the internal consistency for the scale was Cronbach's ${\alpha}=.84$. Conclusion: The reliability and validity of the 15 item person-centered critical care nursing scale were verified. It is expected that the use of this scale would expand person-centered care in critical care nursing.
