Objectives : To investigate the effect of overtime work on fatigue symptoms among Korean female workers. Methods : A total of 1,875 subjects were analyzed using the structured questionnaire, which was composed of overtime work, fatigue symptom, and background characteristics. Data analysis included multiple regression to test for a relationship of overtime work with fatigue symptom while statistically controlling for demographic and occupational variables. Results : Overtime work was more common in those with shorter work years of 3 or less than in those with longer work years. Overtime work was more popular in day workers than in shift workers. No significant difference of smoking and drinking state was observed between two groups. Subjective fatigue symptoms were significantly higher in overtime workers than in workers without overtime work. In a multiple regression analysis with significant control variables, overtime work was associated with 0.31 more fatigue symptom(p<0.001). Conclusion : Our findings suggest that overtime work may increase risks for fatigue symptom. Therefore, preventive strategies will be needed to control the negative effect of overtime work on health status of female workers.
This study was to investigate 1) the correlation of serum Ca, with depression and anxiety ; and 2) the effect of Ca intake on those symptoms. The subjects were three females and two males who were 53-66 years old with the severe subjective symptoms of depression and anxiety. They have taken more than twice Ca of RDA(recommended dietary allowances for Koreans) daily for 6 months(dietary treatment). The prestudy Ca intake of the subjects was low: 60% of RDA for Koreans. Their serum Ca concentration was also low: 6.67 $\pm$ 0.15mg/d1 before the dietary treatment. They expressed severs depression and anxiety, with high self scores in a psychological test. Their serum Ca concentration increased to 8.32 $\pm$ 0.17mg/dl after six months of dietary treatment, while the symptoms of depression and anxiety decreased significantly after two months and nearly disappeared after six months. This result seemed to be an effect of the dietary high Ca intake. Serum Ca and the psychological states of depression and anxiety correlated negatively, and the coefficients of determination were high in the results of linear regression analysis of depression and anxiety by serum Ca. Therefore the serum Ca concentration could be a good marker to predict depression or anxiety relatively well. The continuous high Ca intake could decrease the probability of developing depression or anxiety and mitigate their symptoms because serum Ca concentration increased, while the state of depression and anxiety decreased with the increased Ca intake.
The purpose of this study is to evaluate the relationship between ocular components and refractive error for human eye. Ocular components were measured by keratometry, phakometry, and ultrasonography. Refractive error was measured by subjective refraction on 38 subjects aged from 17 to 30. The results were as follows; 1) Refractive error and axial length, vitreous chamber depth, axial length/corneal radius were highly correlated that the correlation coefficients were 0.95, 0.96, 0.95, respectively. 2) Refractive error and corneal radius, corneal power, lens thickness were correlated with the correlation coefficients for 0.60, 0.66, 0.67 respectively. 3) There were no significant correlation between refractive error and corneal thickness.

Sentiment analysis, a branch of natural language processing that classifies and identifies subjective opinions and emotions in text documents as positive or negative, can be used for various promotions and services through customer preference analysis. To this end, recent research has been conducted utilizing various techniques in machine learning and deep learning. In this study, we propose an optimal language model by comparing the accuracy of sentiment analysis for movie, product, and game reviews using existing RNN-based models and recent Transformer-based language models. In our experiments, LMKorBERT and GPT3 showed relatively good accuracy among the models pre-trained on the Korean corpus.

Background and objectives: Bacterial vaginosis (BV) is recognized as the most prevalent type of vaginal infection, impacting approximately 19-24% of women in their reproductive years. The recurrence rate of BV is significant, negatively impacting the well-being of affected women. This study aimed to compare the therapeutic effects of a polyherbal Unani formulation and metronidazole in treating bacterial vaginosis. Methodology: In this prospective patient blinded standard controlled trial, a total of 40 individuals with a clinical diagnosis of bacterial vaginosis were randomly assigned to receive either an active control treatment (n = 20) or a test drug (n = 20). In the test drug combination of Acacia catechu, Azadirachta indica and Quercus infectoria in tablet (1g) form in the dose of 2 tablets orally twice daily with water was administered for 3 weeks. In the active control standard drug, metronidazole 400 mg tablet, orally twice daily was given for one week. The primary outcome measure was clinical cure; H. negative Amsel's criteria and a reduction in subjective symptoms, while the secondary outcome measure was an improvement in SF-36 quality of life (QOL). Results and conclusion: Both the experimental treatment and the metronidazole demonstrated a significant clinical cure for bacterial vaginosis as well as an increase in health-related quality of life. Based on these findings, it appears that the test medication is a potent Unani formulation for the treatment of bacterial vaginosis. A well conducted trial with a bigger sample size is required to corroborate these findings.

Objectives: The aim of this study was to investigate the correlation between fatigue degree and Comprehensive diagnosis of Qui Xui Shui in patients with functional dyspepsia. There again, we investigated an association between scores obtained from Comprehensive diagnosis of Qui Xui Shui and state of skin sympathetic tone or cardiovascular reactivity. Methods: Subjects were 56 patients with Functional dyspepsia and 8 healthy People. Fatigue degree was assessed by questionnaires consisting of subjective complaints of fatigue. Comprehensive diagnoais of Qui Xue Shui was investigated by questionnaire and physical examination, total score and composition score were calculated from the symptom score. Skin sympathetic tone was measured by Ryodoraku Score(RS) and Cardiovascular Reactivity(CV Reactivity) was checked by Pulse diagnostic apparatus. All patients were divided into two groups by RS $40{\mu}A$(below and above) or by CV Reactivity(decreased and increased or not decreased). Results: There was highly significant correlation between Fatigue Degree and total score and each composition score of Comprehensive diagnosis of Qui Xui Shui. And total score of patients was significantly higher than that of health controls : in the patients, females than males. Significance related with the level of RS $40{\mu}Aor$ the state of CV Reactivity were not remarkable in both patients and health control group. Conclusions: Fatigue degree seems to have a special feature reflecting the state of Comprehensive Diagnosis of Qui Xui Shui in patients with functional dyspepsia.
The subject of this study was to yield data of dietetic education which could help the male teachers to live a desirable dietary life by analying the degree of balance of the diet, the interests in health and the subjective symptoms in disease, and finding the problem in the present dietary habit and the health state. Rusults were as follows: 1. The most regular meal in a day lunch and the most irregular was dinner. The sixties had meals most regularly. 2. The amount of smoking had influence on respiratory system and hepatobiliary system while daily amount of coffee intake influenced cardiobascalar system, diabetes mellitus and joint system. The amounts and the frequencies of alchol intake had no differences. 3. The factors which had meaningful relations with dietary habit were as follows; Salted food and so on had influences on cardiobascular system, spicy food on general disease, lipid intake including fried food, jun, bokchum on joint system, instant food and so forth on respiratory system. Fruit and so forth had influences on diabetes, salted food on hepatobilitary system.
The purpose of this study is to define the effects of the roles played by the Doulas : one group educated on the conventional Lamaze method known to have effects on birth pang during delivery process and the other group educated both on Lamaze and therapeutic touch. On the various factors of delivery, and thereby, provide for some basic data to develop an effective nursing intervention to relieve women of their birth pang. 136 mothers who were hospitalized in a general hospital from June 13, 1998 to May 13, 1998 to May 13, 1999 to deliver their first babies were sampled to be divided into control group, test group I and test group II and thus be subject to interviews and observations. As for the tool of study, melzack's(1975) 'pain scale', McCaffery's(1972) and Mcrachlan's(1974) 'pain expression scales' and Spielberger's (1975) 'anxiety scale' were used. The preparatory educational programs consisted of 5week Lamaze method and therapeutic touch. The research, design was quasi-experimental, non equivalent, posttest only control group design. The collected data were processed using the SPSS/PC statistics software for frequencies, means and one-way Anova as well as Tukey HSD and Scheffe test as post hoc for individual comparison. Moreover, chi-square test was used to test the differences between groups, while Pearson's correlation coefficients were analyzed to determine the correlations between anxiety and variables. The findings are as follows ; 1. The birth pain of the mothers delivering first babies scored in a subjective and objective pain scale; 1) There was a significant difference of subjective birth pain at 8~10cm opening of cervix between control group and two test groups. 2) There was no significant difference of objective birth pain as per opening of cervex among three groups in terms of sweating, facial movement, bodily posture and vocal changes. 2. There was no significant difference of trait anxiety among three groups. however, there was a significant difference of state anxiety during labor process between control group and two test groups. On the other hand, all the three groups showed a significantly lower level of anxiety during labor process than when they were carried to the hospital. 3. There was a significant difference of the time of total and first-stage labor among three groups, while there was a significant but small difference of the time elapsed from 8~10cm cervix open to the full among three groups. 4. Two test groups showed a higher frequency of natural deliveries than the control group. 5. Two test groups were subject to these drugs than the control group. In conclusion, it was found that the test group I and II showed a shorter delivery time than the control group, a higher frequency of natural delivery and a lesser use of anodyne or epidural. In particular, this study is significant to develop a nursing intervention service or a therapeutic touch which the nursing administrators can apply to their hospitals in marketing programs.

The purpose of this study was to examine the factor of the quality of elderly women's sleep. The subjects in this study were 198 elderly women who were at the age of 60 and up. One instrument used to assess their quality of sleep was Buysse, et. al.(1989)'s Pittsburgh Sleep Quality Index(PSQI), and the other used to check their urinary incontinence was Jackson, et. al.(1996)'s Urination Symptom Inventory. The collected data were analyzed by the statistical package SPSS 18.0. The elderly women got $7.09{\pm}4.29$ in the quality of sleep of the PSQI, and 67.7 percent suffered from sleep disorders. Among the subfactors of the PSQI, their subjective quality of sleep was low, and the quality of sleep during, sleep latency was low as well. And their sleep disturbance was great. In contrast, the effectiveness of their habitual sleep was relatively good, and they didn't take medicine such as a sleep pill a lot, and their functional sleep disorder in the daytime wasn't great. There were differences in the quality of sleep according to their education, financial state, self-rated health status and family relations, and whether they worked out on a regular basis or not made a difference to that as well. No differences were found according to age, religion, occupation and having a coffee or not. There was a positive correlation between their quality of sleep in the PSQI and urinary incontinence(r=.51, p=.000). Out of the subfactors of the PSQI, the sleep disturbance factor was most closely linked to urinary incontinence(r=.465, p=.001). Finally, urinary incontinence and subjective health status were identified as the variables that exerted a statistically significant influence on the quality of sleep. Those variables made a 31% prediction of it.
Purpose: This study was to test the effects of a full body massage on labor pain and delivery stress reaction for primipara during labor. Method: This study employed a quasi- experimental method(nonequivalent control group, pre-post test design). The subjects of this study were 57 primipara hospitalized at the U OB & GYN hospital in Inchon from November 1. 2001 to July 31, 2002. 28 women were assigned to the experimental group and 29 to the control group. The experimental group was given 20 minutes full body massage for each of three delivery phases. The control group was given conventional delivery care. The levels of labor pain were measured by the Visual Analogue Scale and the expression scores of the labor pain and the levels of delivery stress reaction were measured by pulse rate, respiration rate, and blood pressure, and State-Anxiety Scale. Data were analyzed using the repeated measures analysis of covariance(ANCOVA), t-test, $X^2$- test, simple ANCOVA with SPSS program. Result: There was no interaction effect between time and group(F=.370, p=.693), but significant time effects were found for subjective labor pain(F=3.840, p=.028). There was no interaction effect between time and group(F=.112, p=.894), but significant group effects were found for objective labor pain(F=12.299, p=.001). There was no interaction effect between time and group for PR(F=.172, p=.843), RR(F=.626, p=.539), SBP(F=.089, p=.915), DBP(F=.748, p=.479), but significant group effects were found for SBP(F=7.547, p=.008). The level of status anxiety of the experimental group was significantly lower than the control group(F=11.787, p=.001). Conclusion: This study showed that the full body massage has partially positive effect on labor pain and delivery stress reaction. Therefore this study suggested that the full body massage might be used clinically to help primipara during labor.
