This study was designed to measure the degree of work stress perceived by clinical nurses working in psyciatric ward, and to identify the factors influencing the difference of work stress. The survey method was used and the subjects of this study consisted of 135 psyciatric nurses from 7 university hospitals and 4 provincial general hospitals. The data were collected from August 1 to 20, 1988. The instrument used for this study was PNOSS(Psychiatric Nurse Occupational Stress Scale) which was developed by Bai(1989). The confidence verification of this instrument was computed and the Cronbach $\alpha$ was 0.94050. Data were analysed by t-test and ANOVA on 5% significant level with SPSS program. The results of study were summerized as follow : 1) The degree of perceived stress among psychiatric nurses was considerably high(4.32 out of 6.00). 2) Among the stressors, inadequate staffing(5.04), hospital administrational problems (4.7) and the conflict of nurse-patient relationship were identified as the stress factors with high rank of degree of stress. 3) There was significant relationship between the degree of stress and the demographic variables of nurses such as the marital status, educational level, and the motivation of working in psychiatric ward. 4) There was significant relationship between the job-related variables such as the working duration, the motivation of working and nurse's attitude toward the psychiatric patients. 5) The relationship between several stress factors and some of the demographic and the job-related variables were significantly identified.

Shaped Sound Focusing is defined as the generation of acoustically bright shape in space using multiple sources. The acoustically bright shape is a spatially focused region with relatively high acoustic potential energy level. In view of the energy transfer, acoustical focusing is essential because acoustic energy is very small to use other type of energy. Practically, focused sound shape control not a point is meaningful because there are so many needs to enlarge the focal region especially in clinical uses and others. If focused sound shape can be controlled, it offers various kinds of solutions for clinical uses and others because a regional focusing is essentially needed to reduce a treatment time and enhance the performance of transducers. For making the shaped-sound field, control variables, such as a number of sources, excitation frequency, source positioning, etc., should be taken according to geometrical sound shape. To verify these relations between them, wavenumber domain matching method is suggested because wavenumber spectrum can provide the information of control variables of sources. In this paper, the procedures of shaped sound focusing using wavenumber domain matching and relations between control variables and geometrical sound shape are covered in case of an acoustical ring.

Pulse is one of the basic diagnostic information of TKM(Traditional Korean Medicine). To quantify and standardize pulse diagnosis, we had collected an amount of clinical data from May 2005 by using newly developed pulse analyzer. But there were many noises in pulse wave according to measuring method, environment, operator and condition of patient. So some data can’t be included for analyzing diagnosis. To reduce noises from measuring pulse and to collect reliable pulse wave data, we made the process map of measuring method and applied six sigma project. With this we can improved the method of measuring pulse wave in collecting clinical data. The project follows a disciplined process of five macro phases: define, measure, analyze, improve and control (DMAIC). A process map and C-E diagram are used to identify process input and output variables. The major input variables are selected by using C&E matrix, and process map is developed by analyzing input variables. And the optimum process conditions are going to be controled to avoid in increasing loss of collecting pulse wave data.

Purpose: This study is a research study to investigate the effects of multicultural experience, perception, and multicultural efficacy on nursing students' multicultural acceptance. Method: The relationship between variables was analyzed using SPSS/WIN 25 program by Pearson's correlation coefficient, and the effect of multicultural experience and perception and multicultural efficacy on multicultural acceptance was analyzed by multiple regression analysis. Results: TVariables affecting multicultural acceptance were multicultural awareness (β=0.30, p<001) and multicultural efficacy (β=0.49, p<.001), and multicultural efficacy had a significant effect on multicultural acceptance. In the results of the regression model, among the variables of multicultural awareness and multicultural efficacy, the multicultural efficacy variable had a greater effect on multicultural acceptance, and both variables had a positive effect on multicultural acceptance. The explanatory power of the regression model for multicultural acceptance was 57.5% (F=59.33, p<.001). Conclusion: Factors affecting multicultural acceptance of nursing students are multicultural awareness and efficacy. Support should be provided to provide opportunities to broaden acceptance.

Objectives: This study investigates lay beliefs about the etiology and treatments of tic disorder and Tourette's syndrome, as well as identifying sociodemographic and personality variables affecting these beliefs among South Koreans. Methods: In total, 673 participants (mean age $41.77{\pm}12.03$ years) completed an online survey regarding their beliefs about tic disorder and Tourette's syndrome. The factors related to their lay beliefs about the disorders were analyzed, and the correlates were investigated. Results: Results indicated that lay people in South Korea held strong beliefs that the causes of tic disorder and Tourette's syndrome lie within the parenting/psychological and neurological/biological categories, compared to the dietary/environmental one. Among the sociodemographic variables, sex, age, and levels of subjective mental health knowledge were primarily associated with the aforementioned beliefs. Familiarity with tic disorder and Tourette's syndrome was also associated with these beliefs. Among the personality traits investigated, extraversion and conscientiousness had significant influences on the beliefs people had about tic disorder and Tourette's syndrome. Conclusion: The results suggest that both policy makers and mental health service providers should adopt a strategic approach for developing and implementing health education interventions about tic disorder and Tourette's syndrome because individual sociodemographic variables, familiarity with the disorders, and personality traits are all associated with the beliefs about these disorders.

Purpose: Clinical observation and research findings show that acute traumatic coagulopathy (ATC) is a major factor that must be addressed in the early care of severe trauma patients. ATC is associated with increased transfusion requirements and poor clinical outcomes. This study aimed to correlate the early predictable factors of ATC with the outcomes in severe trauma patients. Methods: Retrospective data from the trauma registry on severe trauma patients (Injury Severity Score (ISS) ${\geq}16$) were used to identify variables independently associated with coagulopathy. Univariate associations were calculated, and a multivariable logistic regression analysis was used to determine variables independently associated with ATC. Results: Patients were mostly male, aged $51.9{\pm}17.8$ years, with an injury severity score of $24.1{\pm}12.4$. ATC, as diagnosed in the emergency department (ED), occurred in 17% of the severe trauma patients. Using a multivariable logistic regression analysis, early predictable variables independently associated with ATC were base deficit (odds ratio (OR): 13.03; 95% confidence interval (CI): 3.47-48.93), acute liver injury (OR: 4.24; 95% CI: 1.06-17.00), and transfer from another hospital (OR: 21.00; 95% CI: 3.23-136.60). Conclusion: ATC is associated with mortality in severe trauma patients, and some variables associated with trauma and shock are an independent predictors of ATC. These variables contribute to the early recognition and management of coagulopathy, which may improve the outcome from trauma resuscitation.

Objective : This study was conducted to assess the clinical significance of traumatic brain stem injury (TBSI) reflected on Glasgow Coma Score (GCS) and Glasgow Outcome Score (GOS) by various clinical variables. Methods : A total of 136 TBSI patients were selected out of 2695 head-injured patients. All initial computerized tomography and/or magnetic resonance imaging studies were retrospectively analyzed according to demographic- and injury variables which result in GCS and GOS. Results : In univariate analysis, mode of injury showed a significant effect on combined injury (p<0.001), as were the cases with skull fracture on radiologic finding (p<0.000). The GCS showed a various correlation with radiologic finding (p<0.000), mode of injury (p<0.002), but less favorably with impact site (p<0.052), age (p<0.054) and skull fracture (p<0.057), in order of statistical significances. However, only GOS showed a definite correlation to radiologic finding (p<0.000). In multivariate analysis, the individual variables to enhance an unfavorable effect on GCS were radiologic finding [odds ratio (OR) 7.327, 95% confidence interval (CI)], mode of injury (OR; 4.499, 95% CI) and age (OR; 3.141, 95% CI). Those which influence an unfavorable effect on GOS were radiologic finding (OR; 25.420, 95% CI) and age (OR; 2.674, 95% CI). Conclusion : In evaluation of TBSI on outcome, the variables such as radiological finding, mode of injury, and age were revealed as three important ones to have an unfavorable effect on early stage outcome expressed as GCS. However, mode of injury was shown not to have an unfavorable effect on late stage outcome as GOS. Among all unfavorable variables, radiological finding was confirmed as the only powerful prognostic variable both on GCS and GOS.
