This study aims to compare a self-reported and expert-observed method on ergonomic risk factors of Work-related Musculoskeletal Disorders (WMSDs). The checklist was developed based on the results of previous studies, and the symptoms of WMSDs were obtained using a self-reported questionnaire from 1,029 shipyard workers. The risk factors were assessed through the self-report by workers and video analysis by ergonomists. The symptom prevalence at the low back (59.2%), shoulders (50.8 %), and knees (49.7%) were relatively higher than those at other body parts. Odds ratios (ORs) by body parts were 2.48 to 2.90 for the risk job, and the ORs were significantly different from those of the low risk job. The risk factor scores by body parts between workers and ergonomist were very high correlation(r=0.82 to 0.92). The rates of self-report from risk job were 54.0% (elbow and arm) to 72.1 % (low back), but sometimes overestimated(105.7 to 122.6%) than those by ergonomists. The checklist, developed in this study, will be an efficient tool for the evaluation of risk jobs using self-report by workers.
This study is intended to improve parental capacity from the viewpoint of children's happiness. It extracts a core parental capacity for children's happiness from the international index such as OECD well-being, UNICEF Children's welfare, International survey of children's well-being, and Korean children's key index. Based on the extracted core parental capacity, this study developed a self-checklist aiming to perceive parents' capacity status and suggest a political plan in order to improve parents' capacity for children's happiness. The self-checklist has a total of 66 questions and is composed of 7 domains; Child development, Health and Safety, Family relation, Physical and material environment, Play, Guidance in life, and Community engagement. The results from the survey are as follows. The domains of Development of children as well as Health & Safety are reported as the highest value at 4.1 point; on the contrary, those of Guidance in life and Community engagement are reported as the lowest value at 3.8 point. In terms of age, it was reported that the capacity of parents under 35 years-old was better than that of parents over 35 years of age. As for family income, it was revealed that the order of parents' capacity generally depends on the family income.
Purpose: The purpose of this study was to evaluate measurement properties of self-report questionnaires for studies published in Korean nursing journals. Methods: Of 424 Korean nursing articles initially identified, 168 articles met the inclusion criteria. The methodological quality of the measurements used in the studies and interpretability were assessed using the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist. It consists of items on internal consistency, reliability, measurement error, content validity, construct validity including structural validity, hypothesis testing, cross-cultural validity, and criterion validity, and responsiveness. For each item of the COSMIN checklist, measurement properties are rated on a four-point scale: excellent, good, fair, and poor. Each measurement property is scored with worst score counts. Results: All articles used the classical test theory for measurement properties. Internal consistency (72.6%), construct validity (56.5%), and content validity (38.2%) were most frequently reported properties being rated as 'excellent' by COSMIN checklist, whereas other measurement properties were rarely reported. Conclusion: A systematic review of measurement properties including interpretability of most instruments warrants further research and nursing-focused checklists assessing measurement properties should be developed to facilitate intervention outcomes across Korean studies.
Objectives: This study was conducted to investigate the relationships among job stress, job satisfaction, and mental health in marine officers. Methods: The researchers gathered data on marine officers working at a harbor in Chungcheong Province, South Korea, using a self-reported questionnaire. Mental health was measured by the Symptom Checklist-90-Revision (SCL-90-R), and general characteristics including socioeconomic factors, job stress, and job satisfaction were measured by structured questionnaires. Multiple regression analysis was performed to investigate the relationships among job stress, job satisfaction, and mental health status according to the symptom dimensions of the SCL-90-R. Results: Among the marine officers, obsessive-compulsive behavior, depression, and somatization were the most problematic symptoms. Those who reported poor health, low job satisfaction, and high job stress had a higher prevalence of psychoticism, somatization, depression, anxiety, and phobic anxiety. Conclusions: An occupational health system should be introduced that would regularly check the mental health of marine officers in charge of ships and sailors, in order to help reduce their stress levels, enhance their job satisfaction, and thereby improve their mental health.
Purpose: Bruxism is commonly considered a major risk factor for temporomandibular disorders (TMD), and the psychosocial factors had been one of the etiologic factor of bruxism. But there are still unsolved issues on the relationship between sleep bruxism and TMD and the etiologic factors of bruxism. This study is aim to evaluate the clinical and psychosocial characteristics according to diagnostic grade of bruxism in TMD patients. Methods: Three hundred subjects were enrolled who were under the stabilization splint therapy for TMD. Recently international consensus proposed a diagnostic grading system of "possible", "probable", and "definite" sleep or awake bruxism for clinical and research purpose. According to their suggestion, we classified these subjects as self-reported bruxism (SRB) and wear facet bruxism (WFB). We investigated the clinical characteristics (sex, age, chief complaint, pain duration, visual analogue scale), sum of tenderness (temporomandibular joint, masticatory muscles, cervical muscles), diagnosis of TMD according to research diagnostic criteria (the Research Diagnostic Criteria for Temporomandibular Disorders, RDC/TMD), headache, subjective sleep quality (Pittsburgh Sleep Quality Index, PSQI), and psychosocial characteristics (Symptom Checklist-90-Revised, SCL-90-R) in enrolled subjects. We compared the clinical and psychosocial characteristics between these bruxism groups. Results: There were no significant correlation between self-reported and WFB (p=0.13). SRB subjects more reported pain as a chief complain than subject who did not report bruxism (p=0.014). The mean score of global PSQI was significantly higher in SRB than in did not report positively subjects (p=0.045). The mean score of anxiety and phobic anxiety was significantly higher in SRB than in did not reported positively subjects (p=0.045, p=0.041). Conclusions: Although bruxism is regarded as risk factor of TMD, this study showed inconsistent result between SRB and clinically detected bruxism by wear facet on slpint. We suggest that the clinician should consider with extreme caution when they assess SRB.
Purpose : The purpose of this study was to investigate the effectiveness of cardiopulmonary resuscitation (CPR) and automated external defibrillator (AED) education for school teachers by questionnaire survey including the knowledge, self-efficacy and skills of CPR and AED after basic life support (BLS) education. Methods : The subjects were school teachers who participated in BLS education from 24 Nov. to 1 Dec. 2012. They completed the self-reported questionnaire based on BLS skill checklist. Results : There was a statistically significant increase in the knowledge(p <.001), self-efficacy (p <.001) and skills(p <.001) of CPR and AED after BLS education. The correlation existed conspicuously between knowledge versus self-efficacy(r =.409, r =.387), knowledge versus skill(r =.442, r =.084), and self-efficacy versus skills (r =-.148, r =.047) of CPR and AED before and after BLS education. Conclusion : After BLS education, most of the participants found the program was easy and useful to perform. Participants had the willingness to do CPR and AED and wanted to teach BLS to others. It is necessary to provide BLS education for school teachers by systematic approach.

Purpose: This study was conducted to explore the relationship between simulation-based clinical judgment and performance ability for tracheal suction in nursing students. Methods: With a convenience sampling, 207 nursing students participated in this descriptive study. Lasater clinical judgment rubric was used for self-reported clinical judgment in addition to observe the skill of tracheal suction using a checklist. Data were analyzed by descriptive statistics, t-test and Pearson's correlation coefficients using the SPSS/WIN 22. Results: A scenario with pneumonia patient was developed to observe the skill of tracheal suction during simulation-based practices. Then self-reported clinical judgment was scored. The mean score of total sum of clinical judgment, total mean of clinical judgment, and performance skill were $36.44{\pm}4.82$, $13.44{\pm}1.71$, and $42.32{\pm}5.05$, respectively. Statistically, students having good skills in suction showed significant differences in clinical judgment of interpreting (p=.031) compared to students having fair skills. Conclusion: The results of this study show that a structured debriefing method utilizing Lasater clinical judgment rubric is helpful. Also, simulation-based practice related to adult nursing in the respiratory system was useful for increasing the core basic skills among nursing students.
Objectives: Sleep problems has been consistently reported as a suicidal risk factor in adults and, recently, also in adolescents. In this study, dividing study subjects by the previous suicidal behaviors (suicidal vs non-suicidal), we compared the group differences of suicidal risk factors, and examined the possibility of sleep as a suicidal risk factor. Methods: Study subjects were 561 (271 boys and 290 girls) from a community sample of high school students. Suicidal Risk Behavior Checklist, Center for Epidemiological Study-Depression (CES-D), Symptom Checklist-90-Revision (SCL-90-R) Anxiety and Aggression subscale, Pittsburg Sleep Quality Index (PSQI) were done. Results: Forty six students (8.1%) reported previous actual self-harm behavior as a suicidal attempt, 181 students (32.4%) reported having suicidal thought only. Three hundred thirty four students (59.5%) reported no previous suicidal behavior (thought and attempt, both). Suicidal behavior group showed higher score on risk behaviors such as school violence, substance use and internet addiction. CES-D, SCL-90-R, PSQI showed significant group difference. Logistic regression analysis showed suicidal risk were significantly associated with depression, stress in suicidal risk factors and sleep latency, daytime dysfunction in PSQI. Analysis of variance (ANOVA) shows the most prolonged sleep latency and increased index of all PSQI components except sleep efficiency in suicidal attempt group. Conclusions: Sleep Problems had a strong association with the suicidal risk behavior in adolescents. Sleep problems, especially, prolonged sleep latency, daytime dysfunction might be important markers for suicidal behavior. Screening for sleep problems in adolescents are encouraged for the parents, school teachers, and related medical physicians.
The purpose of this study is to investigate elementary school science gifted students' perceptions about Earth systems and environmental problems. A total of 28 students in the attached center for science gifted education to the university participated in this study. Through the survey, participating students were asked to respond to their self-reported knowledge level, the perceived danger levels, certainty, and tangibility of the selected 13 Earth environmental problems. The DAET (Draw-An-Earth Test)-Checklist were developed and used to analyze the images of the Earth drawn by students. Additional interviews were conducted to clarify the meanings and components of students' image. Results indicated that a total of 80 components regarding Earth systems, 11 components of Earth systems interaction, and 4 components related to Earth systems literacy were identified through the DAET-Checklist and additional interviews. Regarding the students' self-reported knowledge level, they reported that they were most knowledgeable about air pollution, global warming, and water pollution. and they also recognized global warming, air pollution, and water pollution as the most dangerous problem. Results indicated that participants were certain that acid rain, air pollution, and water pollution were problematic, and that acid rain, air pollution, and forest desertification were tangible issues. It is anticipated that this study contributes to understanding the elementary school science gifted students' perceptions toward the selected Earth systems and environmental problems.

Objectives : This study was designed to develop and standardize a checklist for ergonomic risk factors, and to provide ergonomic guidelines for managing cumulative trauma disorders (CTDs) in automobile assembly lines. Methods : The Checklist for Ergonomic Risk Factors (CERF-1) was developed based on the results of previous studies, and then modified after performing pilot study. Information on the symptoms possibly related with CTDs was obtained using a self-reported Questionnaire from 465 automobile assembly workers. Their job conditions were examined to assess risk factors through both direct observation and video analysis. Results : Rate of detecting risky job through CERF-1 was 85.6%, and was similar to that (88.8%) by Occupational Safety and Health Adminstration(OSHA) checklist but higher than that (63.7%) by American National Standards Institute(ANSI) Z-365. Relationship of the exposure scores derived from CERF-1 with levels of symptom was greater (r=0.49) than OSHA (r=0.28) and ANSI Z-365 (r=0.22). Considering the relationship, jobs scoring higher than 16 could be classified as the Risk Job. and lower than 16 as the Low Risk Job. Sensitivity and specificity of the Risk Job were 92.5 % and 31.5 %, respectively. Odds ratio (OR) after age adjustment was 5.69 (95 % confidence interval 3.15-10.29) for the Risk Job, and these ORs were significantly different from those of the Low Risk Job. The exposure scores were Quite valid, in that the scores at the main survey were significantly correlated with those at the follow-up survey, as suggested by test-retest(r=0.88) and inter-rater reliability(r=0.80). Conclusions : The CERF-1, developed in this study, will be an efficient tool for evaluation of risk jobs for CTDs in automobile assembly lines, and can be used easily by health care providers.
