This study was conducted to find out the relationship between dental anxiety and self-efficacy, physical and psychological condition and expected self-efficacy. The objective of this study was also to provide foundation for appropriate dental hygiene intervention model for scaling. In this study, anxiety reactions were measured among 178 patients, who made appointment with dental hygienists for scaling between May and July, 2009. The analysis was done in SPSS 12.0 statistical program which confirmed Cranach's alpha value. Technical statistics, t-test and One-way ANOVA, correlation and regression were also used. The result of the study is following: While dental hygienist conducts scaling, the dental anxiety was each measured in following categories: Thus male, age between 40 and 50, single, high school graduated and unemployed were measured highest dental anxiety among various groups. Dental Fear Scale demonstrated the validity of relationship between dental anxiety and self efficacy. The correlation was equated as r=-.409(p<0.01). In the other words, the higher self efficacy, the lower dental anxiety. The relationship between dental anxiety and physical and physiological condition was relevant. Physical condition was r=-.229(p<0.01) And then, the psychological condition was r=-.299(p<0.01). Thus, better physical and physiological condition results in less dental anxiety. The relationship between expected Self-efficacy and dental anxiety is also valid. The dental anxiety after performance accomplishment is r=-.239(p<0.01), after vicarious experience is r=-.195(p<0.01), after verbal persuasion is r=-.152(p<0.05), after recognition of physiological state is r=-.410(p<0.01). In conclusion, sex, age, marital status, education level, employment, physical condition, physiological condition are all relevant to dental anxiety(F=8.834). Both independent and dependent variables p<.05 have 37.5% persuasiveness.

The purpose of the current study was comparative analysis of autonomic and electrocortical responses to passive and active touch of the tektites with different subjective emotional preference. Perspective goal of the project is development of a template for classification of tactile stimuli according to subjective comfort and associated physiological manifestations. The study was carried out on 36 female college students. Physiological signals were acquired by Grass and B10PAC 100 systems with AcqKnowledge III software. Frontal, parietal and occipital EEG (relative power spectrum /percents/ of EEG bands - delta, theta, slow and fast alpha, low and fast beta), and autonomic variables, namely heart rate (HR), respiratory sinus arrhythmia (RSA), pulse transit time (PTT), respiration rate (RSP) and skin conductance parameters (SCL, amplitude, rise time and number of SCRs) were analyzed for rest baseline and stimulation conditions. Analysis of the overall pattern of reaction indicated that autonomic response to tactile stimulation was manifested in a form of moderate HR acceleration, RSP increase, RSA decrease (lowered vagal tone), decreased n and increased electrodermal activity (increased SCL, several SCRs) that reflects general sympathetic activation. Parietal EEG effects (on contra-lateral side to stimulated hand) were featured by short-term alpha-blocking, slightly reduced theta and significantly increased delta and enhanced fast beta activity with few variations across stimuli. The main finding of the study was that most and least preferred textures exhibited significant differences in autonomic (HR, RSP, PTT, SCR, and at less extent in RSA and SCL) and electrocortical responses (delta, slow and fast alpha, fast beta relative power). These differences were recorded both in passive and active stimulation modes, thus demonstrating reproducibility of distinction between most and least emotionally preferred tactile stimuli, suggesting influence of psychological factors, such as emotional property of stimulus, on physiological outcome. Nevertheless, development of sufficiently sensitive .and reliable template for classification of emotional responses to tactile stimulation based on physiological response pattern may require more extensive empirical database.

The purpose of this study is to develop the systematic process on the discrimination of Sasang constitution with the pulse diagnosis apparatus. The pulse waves were acquired at the right and the left Guan point with 1420 people who were apparently healthy. In order to minimize the effect of aging on the shape of pulse wave, the age groups of 30s, 40s, and 50s were used. Taeum group was the best to classify, Soyang group was the worst. With the same group size, the sensitivity of Soyang group was increased. Input variables were selected with the consideration of the floating-sink ratio, tests of equality of group means, multiple comparison, multicollinearity, and structure matrix. To increase the sensitivity of Soyang, the variables which could tell the difference between Soyang and Soeum were selected.

The purpose of this study is to review in light at women's subjective. Perceptions of manifestations Premenstrual Syndrome which are known to affect their labor productivity. To this end, 364 women workers were sampled from an industrial factory located in Chonan, Chungchongnam-do and supervised by health manager, through questionnaires, and collected data were processed using SPSS package program. The result of survey can be summarized as follows: The fact that some academic circles are recently raising the issue of premenstrual syndrome. Suggests that the syndrome is being accepted in academic terms, which is contary to the position that the syndrome is just the result of women's mental imagination. However, some factors which are concived to affect woman worker' productivity and efficiency seem to be related to their subjective psychological variables involving their working environment rather than their physiological variabls. Therefore, if a health-promotion program handling their subjective psychological variables be introduced, some factors caused by the pre-menstrual syndroml may be reduced thus increasing their working productivity and. efficiency around their menstrual days.

The complex 2-dimensional movements of fish during an annual migration circuit were generated and simulated by a chaotic model of fish movement, which was expanded from a small-scale movement model. Fish migration was modeled as a neural network including stimuli, central decision-making, and output responses as variables. The input stimuli included physical stimuli (temperature, salinity, turbidity, flow), biotic factors (prey, predators, life cycle) and landmarks or navigational aids (sun, moon, weather), values of which were all normalized as ratios. By varying the amplitude and period coefficients of the klinokinesis index using chaotic equations, model results (i.e., spatial orientation patterns of migration through time) were represented as fish feeding, spawning, overwintering, and sheltering. Simulations using this model generated 2-dimesional annual movements of sea bream migration in the southern and western seas of the Korean Peninsula. This model of object-oriented and large-scale fish migration produced complicated and sensitive migratory movements by varying both the klinokinesis coefficients (e.g., the amplitude and period of the physiological month) and the angular variables within chaotic equations.

In this work, we investigate the correlation between health condition and voice to study the validity and value of voice diagnosis. For this purpose, we collected voices, Health index questionnaires (Short form 36, Psychological Well Being Index) and Sasang Constitution informations on 197 males at the age of twenties. Pitch, jitter, shimmer variables were analyzed by ANOVA and Pearson correlation coefficient. There were no significant correlations between pitch, jitter, shimmer and health questionnaire score in total group regardless of Sasang Constitution. However, We found tendency of correlation between shimmer variables and health questionnaire scores in Taeeumin and Soyangin. In Soeumin and Soyangin, zitter and pitch variables were found to be slightly correlated with health questionnaire scores. Our study suggests the possibility that voice might be related with both health condition and Sasang Constitution. Our finding may motivate research activities towards diverse clinical applications of voice diagnosis and studies of voice characteristics in the Sasang constitution.

Purpose: The purpose of this study was to explore the predictors of cardiovascular risk factors among type 2 diabetic patients. Method: Data were collected from November, 2003 to June, 2004 using a physiological index and questionnaires. Patients(N=159) aged 40 and above were conveniently recruited from health care centers in B city. Data were analyzed with descriptive statistics, Pearson correlation and stepwise multiple regression using SPSS WIN 10.0 program. Results: The cardiovascular risk factors were negatively related with female gender, household monthly income, educational experience about diabetes, physical activity, self-care, self-efficacy and problem oriented coping, while positively related with the duration of diabetes, diabetic family history and depression. Self-care, diabetic family history, female gender, monthly household income, self-efficacy, affective-oriented coping and physical activity predicted 41.5% of the variance in cardiovascular risk factors of diabetic patients. Conclusion: According to the findings of this study, we concluded that cardiovascular risk factors of type 2 diabetic patients are related to the modifiable and non-modifiable variables. Self-care, self-efficacy, affective oriented coping, and physical activity were identified as modifiable variables. Intervention programs to increase those variables are warranted to reduce cardiovascular risk factors among type 2 diabetic patients.

Cardiac surgery is generally followed by a period of routine ventilator support. When the patient seems hemodynamically stable and relatively alert following surgery, respiratory adequacy is tested by the weaning trial. In this study, physiological and clinical prediction of postoperative respiratory adequacy, including values of pulmonary function tests, were examined in an attempt to identity those few variables which predicted the outcome of the ventilator weaning trial following surgery. Our series comprised 27 patients who underwent elective open intracardiac operations at the Department of Thoracic and Cardiovascular Surgery, School of Medicine, Kyungpook National University, from October 1979 to July, 1980. The pulmonary function tests performed on all patients included the following; forced vital capacity [FVC], forced expiratory volume [FEV1.0], forced expiratory flow [FEF 25--75~], residual volume [RV], and functional residual capacity [FRC], measured with a helium dilution technique. Of our 27 patients, 8 were successfully weaned within 20 hours of operation. All patients with cyanotic heart diseases or acquired heart diseases were unsuccessfully weaned. The bypass time in the successful weaning group was shorter in the mean value [82.8 minutes]than in the unsuccessful weaning group [120.5 minutes]. There was a relatively significant difference in the mean values for the two groups in arterial pressure, bleeding amounts and FiO2 among the postoperative monitoring variables, and in forced vital capacity [FVC]. The postoperative clinical assessments appeared vague but corresponded reasonably well to appraisal of success in weaning, especially in variables of cough and self-respiration efforts.

Diabetes mellitus (DM) is considered to be a serious metabolic disease which may cause systemic complications. The present study was designed to clarify a difference on stress, physiological variables and their correlation between diabetic (DM group) and nondiabetic adults (control group). The levels of body weight, waist circumference, blood pressure, body mass index, body fat mass, total cholesterol (TcH), triglyceride (TG), aspartate aminotransferase (AST), alanine aminotransferase (ALT), gamma-glutamyltransferase (GGT), total bilirubin (TB), autonomic balance (AB), stress index (SI), fatigue index (FI), and heart rate (HR) were all significantly higher in the DM group than in the control group. However, the levels of autonomic activity (AA), stress resistance (SR), and electrocardiac stability (ES) were significantly lower in the DM group than in the control group. The percentages of persons with abnormal levels in the Tch, high density lipoprotein, low density lipoprotein, TG, AST, ALT and GGT were significantly greater in the DM group than in the control group. In the correlation of glucose and hemoglobin A1c (HBA1c) to stress indices, the DM group had a significant relationship with AB, SR, SI, FI, ES, and HR, whereas the control group had no significant relationship with these, excepting AB. These results suggest that DM was harmfully associated with body, biochemical and stress indices and that blood glucose and HBA1c levels must be exhaustively regulated.
