Objects : There has been the controversy that menopause may or may not influence the psychological distresses. The purpose of this study was to investigate the correlation between the hormonal status and traits of depression & anxiety in menopausal women. Method : Among the women attending menopausal clinic. menopausal women, defined as who having a amenorrhea for more than 12 months, were selected as a study group(n=83). The control group(n=73), who visited to screen the cervix cancer with regular menstruation, hod no history of hormone replacement therapy. Individual data were collected by self-reporting questionnaires. Depression state was evaluated by Beck Depression Inventory(BDI) and anxiety state by Stale Trail Anxiety Inventory(STAI), and the female hormones such as E2, FSH, and LH were obtained by blood sampling at visting clinic. Statistically the data were processed by t-test and pearson correlation analysis(p<0.05). Results : 1) The mean age of menopausal was 45.3 years. 2) In menopausal women the scores of BDI & STAI were significantly higher than in control group(p<0.05). 3) There were significant differences between menopausal and control group by E2 & FSH. 4) There was no correlation between female hormonal status and the STAI & BDI scores in both groups. Conclusion : Although menopausal women had more traits of depression & anxiety than control group, it was difficult to insist that the lack of estrogen was the only etiological factor for the traits of depression & anxiety in menopausal period. In further studies, we must consider another factors, including biological, sociocultural, psychological factor, as the cause of psychological symptoms during menopausal period.

The clinical efficacies of Korean Red Ginseng for improving sexual function has been reported only by self-reporting questionnaires.AVS-Penogram is a method evaluating natural penile blood flow changes by Gamma-camera after intravenous injection of Techmetium 99$\^$m/-RBC and also stimulating by erotic video tape. To more objectively evaluate the efficacies of Korean Red Ginseng for erectile function, we applied AVS-Penogram as a objective diagnostic tool. AVS-Penogram studies were done in 28 patients with erectile dysfunction after administration of Red Ginseng(19) or placebo(9) group. The pattern of AVS-Penogram before medication were normal type in 4, impossible in 2, unstable in 20, delayed in 1, and mixed in 1. The unstable type were the most prevalent observed in 71.4% of all patients. The patterns of AVS-penogram were 2.2. 13.1 in Red Ginseng group, while in placebo group normal 2, unstable 7. After 4 weeks in Red Ginseng group, there were 3 cases of improved penogram findings, while only 1 in placebo group. There were no statistical significancies in the type of penogram changes on both group. But the maximum radioactivity were improved in 11 patients(57.9%) in Red Ginseng group, while 2(22.2%) in placebo group. There were statistical significancies in comparing the maximal radioactivity of penogram on both group. These AVS-Penogram findings shows, encouraging results of by increased penile blood flow Korean Red Ginseng our medication. Further study is more needed to reconfirm these results by more concentrated active formulations of sapanonin St other active ginsenosides. These promising results will lead to develop a new remedy for erectile dysfunction by Korean Red Ginseng

Purpose: The aim of this study was to compare job satisfaction, quality of life (QOL), incident report rate and overtime hours for 12-hour shifts and for 8-hour shifts in a pediatric intensive care unit (PICU). Methods: A descriptive survey was conducted with a convenience sample of 36 staff nurses from a PICU in a regional hospital in Korea. Data were collected using self-administrated questionnaires regarding job satisfaction and QOL at 6 months before and after the beginning of 12-hour shifts. Incident report rate and overtime hours for both 12-hour and 8-hour shifts were compared. Comparisons were made using $x^2$-test, paired t-test and Mann-Whitney U test. Results: After 12-hour shifts were initiated, job satisfaction significantly increased (t=3.93, p<.001) and QOL was higher for nurses on 12-hour shifts compared to 8-hour (t=7.83, p<.001). There was no statistically significant change in incident report rate ($x^2=0.15$, p=.720). The overtimes decreased from $36.3{\pm}34.7$ to $17.3{\pm}34.9$ minutes (Z=-8.91, p<.001). Conclusion: These results provide evidence that 12-hour shifts can be an effective ways of scheduling for staff nurses to increase job satisfaction and quality of life without increasing patient safety incidents or prolonged overtime work hours.

Objectives: The purpose of this study is to investigate the effects of the 37-hour sleep deprivation on visual discrimination using the Cybernetic Flicker Fusion Analyzer (FLIMK) and to see the correlation between this finding and various subjective scale scores. Methods: Twenty six subjects (20 men 6 women, $24.50{\pm}1.45$ years of age) participated in this study. Subjects remained awake for 37 hours under continuous surveillance. In the morning and evening of two study days, the FLIMK and the self-reporting scale of sleepiness, fatigue, anxiety and mood states were instituted. Results: In FLIMK, the flicker fusion threshold was significantly decreased after sleep deprivation (F=7.66, p=0.01). The number of trials (responses) before reaching fusion frequency threshold was significantly increased after sleep deprivation (F=13.16, p=0.001). The reduction of fusion frequency was correlated with the increase of sleepiness and fatigue (p<0.05), and the number of the trials was correlated with the scores of negative mood, anxiety, and fatigue (p<0.05). Conclusions: These results suggest that 37 hour total sleep deprivation cause the decrement in visual discrimination. The decrease of the fusion frequency after sleep deprivation was correlated with sleepiness and fatigue. Further study is needed to enlighten the biological mechanism of the decrement in visual function after sleep deprivation.

The purpose of this study was to evaluate the relationship among verbal violence experience, verbal violence impact and burnout of operating room nurses. The data were collected by structured self-reporting questionnaires from 202 operating room nurses and were analyzed with descriptive statistics, t-test, ANOVA, Scheffe test, Pearson's correlation coefficients and multiple regression. The level of verbal violence experience and verbal violence impact was 1.96 and 1.67. The level of burnout was 3.08. Verbal violence impact and burnout have a significant positive association with verbal violence experience(r=.39, p<.001; r=.41, p<.001). Verbal violence impact was positively associated with burnout(r=.29, p<.001). Factors influencing burnout were verbal violence experience, verbal violence impact and position(staff nurse) which explained 30% of the variance(F=9.15, p<.001). These findings indicate that verbal violence experiences of operating room nurses have influence on stability and productivity in personal, social aspect and suggest developing the verbal violence prevention program in hospital.

The purpose of the study is to develop a questionnaire that examines unskeptical attitudes in scientific inquiry context. The questionnaire items were developed through literature research, expert review, and statistical analyses for validity and the differences in scores were identified by gender and tracks. A total of 363 high school students participated in the study. To explore the validity evidence of items, the Rasch analysis and the reliability of internal consistency were performed, and the two-way ANOVA was performed to compare the scores of the unskeptical attitudes between gender and academic track. Self-reporting and Likert-scaling 23 items were developed to measure unskeptical attitudes in scientific inquiry context. The items were developed in the sub-domain of scientific inquiry: 'questioning and hypothesis generating,' 'experiment designing,' and 'explaining and interpreting.' Second, the validity and reliability of the unskeptical were identified in a rigorous method. The validity of items were identified by multi-dimensional partial score model analysis through the Rasch model, and all 23 items were found to be fit to model. Various reliability evidences were also found to be appropriate. It was found that there were no significant differences of unskeptical attitude score between the gender and academic track except one comparison. The developed questionnaire could be used to check an unskeptical attitude in the course of scientific inquiry and to compare the effects of scientific inquiry classes.

Objectives : This study aimed to assess the possible association of dental pain with suicidal ideation among adolescents by analysing data from the 2018 Korean Youth Risk Behavior Survey, a nationwide online survey. Methods : Of 62,823 adolescent middle and high school students in Korea, 60,040 participants were selected for analysis, after excluding cases with missing values. Participants were given a questionnaire about their self-evaluation of health including dental pain and suicidal ideation. Logistic regression analysis demonstrated the relationships between dental pain and suicidal ideation after controlling for potential confounding factors. Results : The proportion of Korean adolescents reporting suicidal ideation was 13.3%. The proportion of adolescents who experienced dental pain was 23.4%. Compared to adolescents who did not report dental pain, adolescents who reported experiencing dental pain were significantly more likely to experience suicidal ideation (OR=1.94, p<0.001). In two multivariate models, the relationships between dental pain and suicidal ideation (AOR=1.24, p<0.001) were statistically significant. Conclusions : Dental pain was associated with increased risk of suicidal ideation among Korean adolescents, even when controlling for sociodemographic factors and other health conditions. It is necessary to consider screening adolescent patients who present with dental pain for suicidal ideation.

The purpose of this study was to explore the latent profiles of social achievement goals and to investigate the differences in peer status (perceived popularity, social preference) and aggression (overt, relational, cyber) among those profile groups. Social achievement goals and cyber aggression data was acquired through self-reporting, and perceived popularity, social preference, and overt and relational aggression were assessed through peer nomination. Applying the latent profile analysis(LPA) to 1,239 elementary school students, three distinct groups of social achievement goals were identified: a development-oriented achievement goal group, an average social goal group, and a overall-high social achievement goal group. Using logistic regression analysis, the relationships between the latent group, peer status, and aggression were examined. The result indicated that the higher the social preference, the lower the probability of belonging to the 'overall-high social achievement goal group'. And the higher the cyber aggression, the lower the probability of belonging to the 'development-oriented achievement goal group'. In addition, the higher the relational aggression of the second time, the higher the probability of belonging to the 'overall-high social achievement goal group' as compared to the 'average social goal group'.
