It is well known that a long-term exposure to a loud noise environment affects performance, since it distracts attention, and also is able to evoke stress accompanied by negative emotional states. The purpose of this study was to analyze dynamics of subjective and physiological variables during long-lasting (30 min) exposure to intensive white noise (85 dB[A]). Physiological signals on 23 college students were recorded by BIOPAC, Grass Neurodata systems and AcqKnowledge 3.5 software. Autonomic variables, namely skin conductance level (SCL), non-specific SCR number (N-SCR), inter-beat intervals in ECG (RR intervals), heart rate variability index (HF/LF ratio of HRV), respiration rate (RESP), and skin temperature (SKT) were analyzed on 5 min epoch basis. Psychological assessment (subjective rating of stress level) was also repeated on every 5 min basis. Regression and correlation analyses were employed to trace the time course of the dynamics of the subjective and autonomic physiological variables and their relationship. Results showed that intense noise evokes subjective stress with associated autonomic nervous system responses. However, it was shown that physiological variables endure specific changes in the process of exposure to loud white noise. Discussed are probable psychophysiological mechanisms mediating reactivity to long-term auditory stimulation of high intensity.

In this study, psychophysiological stress was quantitatively evaluated at various car interior noise levels by using Electroencephalogram(EEG). An experiment was performed to investigate the most comfortable range of noise level during simulated driving condition. Twelve healthy volunteers participated in the experiment. They were asked to operate the driving simulator while six levels of interior noise were given, such as 45dB(A), 50dB(A), 55dB(A), 60dB(A), 70dB(A), 80dB(A), and maximal subjective noise level. EEG signals were recorded for 60 seconds in each noise level. The power spectral analysis was performed to analyze EEG signal. At the same time, psychological stress was also measured subjectively by using a magnitude estimation method. The results showed that subjective stress and EEG spectrum indicated a statistically significant difference between noise levels. In particular, high level noise produced an increase in beta power at temporal(T3, T4) areas. It was also found that beta activity was highly correlated with subjective perception of discomfort, and subjects responded to car interior noise as arousing or negative stimuli. Moreover, beta power remained stable above 70dB(A), whereas subjective discomfort continued to increase even above 70dB(A) We concluded that brain waves could provide psychophysiological information of drivers emotional reaction to car interior noise. Thus, EEG parameters could be a new measure to determine optimal noise level in ergonomic workplace design after further verification in various experimental conditions.

Purpose: This study investigated general, psychological, and health-related factors related to subjective health status reported from adolescents in multicultural families. Methods: Data from the seventh Korean Youth Risk Behavior Web-based Survey (2001), collected by the Korean Center for Disease Control, was statistically analyzed using the t-test, analysis of variance (ANOVA), and multiple regression analysis. Results: The average points reported for subjective health status was 3.73(SD=0.87)out of 5 points. A major factor accounting for differences in the subjective health status reported was gender. In addition key differences related to psychological and health-related factors were cognition of stress, satisfaction with sleep amount, and moderate physical exercise. Conclusion: The findings suggest that tailored intervention programs should be provided to prevent adolescent problems in multicultural families. We also recommend the development of a program that can help control the variables identified in this study.

Purpose: This study aimed to present and test a structural model for describing and predicting the factors affecting subjective career satisfaction of nurses experiencing rotation and to develop human resources management strategies for promoting their career satisfaction related to rotation. Methods: In this cross-sectional study, we recruited 233 nurses by convenience sampling who had over 1 year of career experience and who had experienced rotation at least once at G university hospital. Data were collected from August to September in 2016 using self-reported questionnaires. The exogenous variables consisted of rotation perception and rotation stress. Endogenous variables consisted of career growth opportunity, work engagement, and subjective career satisfaction. A hypothetical model was tested by asymptotically distribution-free estimates, and model goodness of fit was examined using absolute fit, incremental fit measures. Results: The final model was approved and had suitable fit. We found that subjective career satisfaction was directly affected by rotation stress (${\beta}=.20$, p=.019) and work engagement (${\beta}=.58$, p<.001), indirectly affected by rotation perception (${\beta}=.43$, p<.001) through career growth opportunity and work engagement. However, there was no total effect of rotation stress on subjective career satisfaction (${\beta}=-.09$, p=.270). Career growth opportunity directly and indirectly affected subjective career satisfaction (${\beta}=.29$, p<.001; ${\beta}=.28$, p<.001). These variables accounted for 65% of subjective career satisfaction. Conclusion: The results of this study suggest that it is necessary to establish systematic and planned criteria for rotation so that nurses can grow and develop through sustained work and become satisfied with their career.

스트레스에 대한 대처방식의 차이는 개인의 심리적 안정에 영향을 미친다. 또한 개인의 특성에 따라 대처방식이 심리적 안정에 미치는 영향력은 달라질 수 있다. 그러나 개인이 가지는 특성 중 문화적 자기에 따라 스트레스 대처방식과 행복의 관계가 달라지는 지에 대하여는 확인된 바 없다. 기존의 문화적 자기관으로 대표되는 개인주의-집단주의 또는 상호독립적-상호협조적 자기는 한국인의 특성을 설명하는 데 한계를 보여왔다. 따라서, 본 연구는 한국문화를 설명할 수 있는 새로운 문화적 자기관인 주체성-대상성 자기를 기준으로 그 관계를 알아보고자 하였다. 분석에 사용된 설문은 총 283부이며, 참여자의 평균 나이는 21.66세(SD = 1.46)이며, 남자는 125명(44%), 여자는 158명(55.8%)이었다. 설문은 행복, 대인관계 만족도, 주체성-대상성 자기, 그리고 스트레스 대처방식(문제해결, 조력추구, 소망적사고, 부인) 등으로 구성되었다. 분석 결과, 주체성 자기가 대상성 자기보다 우세한 집단이 문제해결, 조력추구를 많이 사용하였고, 부인은 적게 사용하였다. 다음으로, 주체성 자기가 대상성 자기보다 강할수록 행복과 대인관계 만족도는 높았다. 마지막으로, 대상성 자기 우세 집단이 주체성 자기 우세 집단보다 문제해결과 조력추구의 대처방식에 있어서 행복과 대인관계 만족도에 미치는 영향력이 유의미하게 높았다. 이러한 연구 결과를 바탕으로 새로운 문화적 자기관의 한국 문화의 이론적 적용과 실제적 활용을 논의하였다.

Purpose: The purpose of this study was to identify the effects of aromatherapy on blood pressure and stress responses of clients with essential hypertension. Method: There were fifty-two subjects divided into an essential oil group, placebo group, and control group by random assignment. The application of aromatherapy was the inhalation method of blending oils with lavender, ylangylang, and bergamot once daily for 4 weeks. To evaluate the effects of aromatherapy, blood pressure and pulse were measured two times a week and serum cortisol levels, catecholamine levels, subjective stress, and state anxiety were measured before and after treatment in the three groups. Data was analyzed by repeated measures of ANOVA, one-way ANOVA, and $X^2-test$ using the SPSS 10.0 program. Results: The blood pressure, pulse, subjective stress, state anxiety, and serum cortisol levels among the three groups were significantly statistically different. The differences of catecholamine among the three groups were not significant statistically Conclusion: The results suggest that the inhalation method using essential oils can be considered an effective nursing intervention that reduces psychological stress responses and serum cortisol levels, as well as the blood pressure of clients with essential hypertension.

In order to investigate and compare the health risk factors of nurses in the operating room(OR nurse) and ward (WARD nurse), the questionnaire survey for subjective symptoms was carried out on 553 nurses(132 OR nurses and 421 WARD nurses) who were employed at seven hospital. The self-administered questionnaries were composed of low back pain, subjective fatigue symptoms, musculo-skeletal symptoms, psychological stress and reproductive function. The results were as follows : 1. In the type of working posture and working environment, there were significant difference between two groups for working posture, waist form, height of working table, satisfaction of chair, lifting & carring. 2. Job satisfaction, duration of work, height of working table, satisfaction of chair, lifting & carring were significantly associated the low back pain. 3. In the complaints of subjective fatigue symptoms, the total mean score was higher in OR nurse than WARD nurse, but there was not significant. The items that the mean score of OR nurse was significantly higher than WARD nurse were 'head feels muddled', 'apt to forget', 'feel choky'. 4. In the complaints of musculo-skeletal syrrptoms, the total mean score was higher in OR nurse than WARD nurse, but there was not significant. The item that the mean score of OR nurse was significantly higher WARD nurse was 'wrist discomfort or pain'. 5. The comparison of spontatenous abortion in married nurses who had the experience of pregnancy were significantly associated the stress risk group. 6. In all of OR and Ward nurses, the job satisfaction is associated with subjective fatigue symptoms, musculo-skeletal symptoms, and stress. In conclusion, it suggested that working posture, working environment, stress, and job satisfaction were health risk factors of nurses working in the operating room. Further prospective intervention studies should be conducted to educate right working posture, improve of working environment, decrease of stress, and increase of job satisfaction.

Purpose: The purpose of this study was to examine the relationship among subjective symptoms, depression, and stress coping behavior of university students. Method: The survey was carried out on a convenience sample of 298 university students. The questionnaire consisted of each scale for symptoms, depression, and stress coping behaviors. Data analysis procedure included the factor analysis for stress coping behaviors, and the correlation analysis describing a relationship among symptoms, depression, and stress coping behaviors. Result: There were significant correlations between depression and the three types of symptoms: general, psychological, and somatic symptom. Subjects using the negative-emotional-response coping and the self-control coping showed a more severe depression, and those using the problem-solvingㆍreappraisal coping and the positive-emotional-response coping showed a milder depression. Subjects using the negative-emotional-response coping complained of all 3 types of symptoms severely, and those using the positive-emotional-response coping complained of general symptoms mildly. Of five stress coping methods, the negative-emotional-response and the positive-emotional-response coping methods were related to both symptoms and depression significantly. Conclusion: This study suggests that the emotional-oriented coping method has more important role for university student’s depression and their subjective symptoms than the problem-oriented coping or social supports seeking coping. Further study needs to be conducted to help students effective coping mechanism for good mental health. Also it is necessary for university students to recognize that their symptoms are associated with depression.

Objectives: Stress is a psychological reaction to stimuli such as anxiety or threat felt by a person either physically or mentally when placed in a difficult situation. Although a relationship between stress and dry mouth has been reported, it remains understudied. The purpose of this study was to investigate the association between stress and subjective dry mouth among the elderly living in a rural region. Methods: A total of 214 people aged ${\geq}60years$ living in a rural area were recruited with an informed consent for a cross-sectional analysis. Information about stress and subjective dry mouth was obtained by an interview survey with a constructed questionnaire. Data on other potential confounding factors (including oral factors) such as socio-demographic data, health-related behaviors, the number of remaining teeth, and subjective chewing ability were also gathered at the same time. Logistic regression models were used to analyze the relationship of stress and dry mouth using SPSS. Results: The Crude odds ratio (OR) of stress awareness affecting subjective dry mouth was 2.59 (95% confidence interval: 1.43-4.68). After adjusting for sex, education, income, smoking, and alcohol intake, the adjusted OR was 2.52 (95% confidence interval: 1.30-4.87) which was statistically significant. Conclusions: Elderly people who were stressed had an approximately 2-fold increase in experiencing subjective dry mouth when compared to their stress-free counterparts.
