BACKGROUND: Statistical analysis is essential in regard to obtaining objective reliability for medical research. However, medical researchers do not have enough statistical knowledge to properly analyze their study data. To help understand and potentially alleviate this problem, we have analyzed the statistical methods and errors of articles published in the Korean Journal of Pain (KJP), with the intention to improve the statistical quality of the journal. METHODS: All the articles, except case reports and editorials, published from 2004 to 2008 in the KJP were reviewed. The types of applied statistical methods and errors in the articles were evaluated. RESULTS: One hundred and thirty-nine original articles were reviewed. Inferential statistics and descriptive statistics were used in 119 papers and 20 papers, respectively. Only 20.9% of the papers were free from statistical errors. The most commonly adopted statistical method was the t-test (21.0%) followed by the chi-square test (15.9%). Errors of omission were encountered 101 times in 70 papers. Among the errors of omission, "no statistics used even though statistical methods were required" was the most common (40.6%). The errors of commission were encountered 165 times in 86 papers, among which "parametric inference for nonparametric data" was the most common (33.9%). CONCLUSION: We found various types of statistical errors in the articles published in the KJP. This suggests that meticulous attention should be given not only in the applying statistical procedures but also in the reviewing process to improve the value of the article.
Intention

PURPOSE: The study was done to verify the effect size of the variables related to the emotional labor of nurses. METHODS: A total of 47 article on variables related to the emotional labor of nurses and published from 2006 to 2014 were used for the meta-analysis. RESULTS: Variables with the largest effect size related to emotional labor were identified as the variables of work task, organization and individual characteristics in descending order of effect size. The sub-factors with the greatest effect size in the work task variable were exhaustion and work commitment, while for organization variables, intention to change jobs had the largest effect size. For individual characteristics, physical symptoms had the largest effect size. CONCLUSION: The results of this study are meaningful as the first study to integrate research results on variables related to the emotional labor of Korean nurses, providing practical data for the management of emotional labor.
Intention

PURPOSE: This review aimed to integrate the results of studies related to job embeddedness of clinical nurses and suggest directions for future research. METHODS: A search for relevant studies was conducted using six databases according to the predetermined index terms “nurse” and “job embeddedness.” A total of 28 studies that met the inclusion criteria were selected and analyzed. RESULTS: The definition of job embeddedness was consistent in the articles, but the terms, scope, and use of tools to determine job embeddedness were not. In addition, no article suggested a theoretical framework. In all the studies except one, the tool used to measure job embeddedness was one revised from Mitchell et al. (2001). In 15 articles, a negative correlation was found between job turnover and turnover intention. Job embeddedness was also found to be associated with nurses' work environment, organizational citizenship behavior, and organizational commitment, and it had a positive impact on these variables. CONCLUSION: Job embeddedness can be used as a major variable to explain nurses's turnover intention. Job embeddedness is multidimensional, and a theoretical framework is needed to explain the job embeddedness of clinical nurses. Tools specific to Korea should be developed to measure the job embeddedness of Korean clinical nurses.

PURPOSE: The purposes of this study were to explore nurse' bullying experiences according to demographic characteristics and to identify effects of workplace bullying and job stress on turnover intention in hospital nurses. METHODS: One hundred sixty-one graduate students working as nurses were recruited. The collected data were analyzed using descriptive statistics, t-test, ANOVA, Pearson correlation coefficient, and Stepwise multiple regression with PASW 18.0. RESULTS: Results show that 23.0% of the nurses interviewed had experienced bullying in the workplace within the last six months and 19.4% had been bullied during the entire employment period. Bullying perpetrators included nurses (52.9%), physicians (23.0%), and patients (17.8%). Bully nurses consisted of senior nurses (63.0%), managers or supervisors (29.6%), colleagues (3.7%), and junior nurses (3.7%). Job turnover intention in hospital nurses was significantly correlated with workplace bullying (r=.20, p=.012) and job stress (r=.37, p<.001). The most significant predictors influencing the turnover intention of hospital nurses were job stress, age, and bullying in total career and these factors accounted for 21.0% of the variance. CONCLUSION: Job stress and bullying significantly influence turnover intention. Therefore, educational programs should be developed and implemented to prevent workplace bullying.

OBJECTIVES: The purpose of this study was to evaluate the relation between intentionally induced internal stress and cyclic fatigue failure of .06 taper ProFile. MATERIALS AND METHODS: Length 25 mm, .06 taper ProFile (Dentsply Maillefer), and size 20, 25, 30, 35 and 40 were used in this study. To give the internal stress, the rotary NiTi files were put into the .02 taper, Endo-Training-Bloc (Dentsply Maillefer) until auto-stop by torque controlled motor. Rotary NiTi files were grouped by the number of induced internal stress and randomly distributed among one control group and three experimental groups (n = 10, Stress 0 [control], Stress 1, Stress 2 and Stress 3). For cyclic fatigue measurement, time for separation of the rotary NiTi files was recorded. The fractured surfaces were observed by field emission scanning electron microscope (FE-SEM, SU-70, Hitachi). The time for separation was statistically analyzed using two-way ANOVA and post-hoc Scheffe test at 95% level. RESULTS: In .06 taper ProFile size 20, 25, 30, 35 and 40, there were statistically significant difference on time for separation between control group and the other groups (p < 0.05). CONCLUSION: In the limitation of this study, cyclic fatigue failure of .06 taper ProFile is influenced by internal stress accumulated in the files.

PURPOSE: The purpose of this study was to verify the effectiveness of the model based on the TPB, behavior-related theories, and exercise-related empirical studies in predicting exercise intention and behavior. METHODS: The subjects who participated in this study were 152 middle-aged women. The data were analyzed by use of SAS PC program and LISREL 8.12a program. RESULTS: 1) The overall fit of the hypothetical model to the data was acceptable(x2 24.01(p=0.0043), x2/df 2.67, RMSEA 0.11, standardized RMR 0.04, GFI 0.97, AGFI 0.84, NFI 0.95, NNFI 0.85). 2) Affect, subjective norm, perceived behavioral control and habit were significant determinants of the exercise intention. Attitude and facilitating conditions were not significant determinants. These six variables explained 43% of the total variance of the exercise intention. 3) Perceived behavioral control and habit were significant determinants of the exercise behavior. Intention and facilitating conditions were not significant determinants. These four variables explained 95% of the total variance of the exercise behavior. CONCLUSION: This study shows the model's applicabiltiy in explaining exercise behavior of middle-aged women, and suggests that we should focus on perceived behavioral control and habit rather than intention to improve exercise behavior of middle-aged women.

PURPOSE: The purpose of this study was to identify the process of overcoming the intention toward turnover experienced by career nurses. METHODS: Data were collected from 10 career nurses though in-depth interviews about their experiences. The main question was "How do you describe your experience of the process of overcoming intention to turnover as a career nurse?" Qualitative data from field and transcribed notes were analyzed using Strauss & Corbin's grounded theory methodology. RESULTS: From the participants' statement, 127 concepts, 34 subcategories and 13 categories were extracted through the open coding process. The core category was discovered to be 'back to the original place'. Phenomenon was identified as 'reached the threshold that cannot be withstood' and this series of process was categorized as having four stages: 'conflict', 'meditation', 'discovery' and 'conquest'. There were three types of overcoming turnover intention in career nurses, 'adjustment', 'compromise', 'self-led'. CONCLUSION: The results of this study produced useful information about the needs of career nurses during the process of overcoming turnover intention based on their stage and overcoming types of turnover intension. Ultimately this study may help decrease the turnover intention of career nurses.

PURPOSE: The purpose of this study was to examine the training effectiveness and behavior towards the elderly of 180 caregiver trainees. METHODS: Data were collected from five caregiver training institutions located in G city. All subjects were surveyed about the training effectiveness and behavior towards the elderly by using the Training Effectiveness Scale and the Behavior towards the Elderly Scale. Data were analyzed by SPSS/WIN 12.0 program. RESULTS: The study subjects gained a training effectiveness score of 3.84 out of 5 points and a behavior towards the elderly score 3.40 out of 4 points. The training effectiveness differed significantly depending on subject's characteristics, intention to work as a caregiver, and hours of training. There were significant differences in behavior towards the elderly depending on their age and hours of training. The training effectiveness was significantly correlated with the level of behavior towards the elderly. CONCLUSION: These findings demonstrated the necessity of developing a level of educational training that will help improve caregiver trainees' care by positively changing their behavior towards the elderly.

OBJECTIVES: This study was carried out to examine the factors influencing the behavioral intention and behavior of workers with non-occupational diseases when utilizing medical facilities, using the theory of planned behavior (TPB). METHODS: The first TPB questionnaire was administered to 3,116 subjects during workers'periodic health examinations at one health examination institute, between September and December in 2000. An investigation of the medical facilities utilization was also conducted by administering a second survey to the 354 subjects (11.4%) adjudged to be workers with non-occupational diseases from the results of the health examination. RESULTS: The medical utilization rate within one month was 41.5%. To investigate the overall relationship between variables, the authors conducted a linear structural equation model analysis, based on the theory of planned behavior. The attitude toward behavior and the subjective norm both positively influenced the behavioral intention (T> or = 2.0). The perceived behavioral control and behavioral intention both positively influenced the behavior (T> or = 2.0) CONCLUSIONS: To improve the medical utilization by workers found to have diseases as a result of their health examination, the implementation of an intervention program will be necessary to increase the behavioral intention and perceived behavioral control, and care givers must pay more attention to eventually converting behavioral intention into actual behaviors.
