BACKGROUND: This study researched the relationship between shift work and one of its relevant health problems, functional gastrointestinal disorders. The study targeted nurses working at a university hospital, and compared the differences in gastrointestinal disorders of shift workers and non-shift workers and identified causes that significantly influence these symptoms. METHODS: In August 2013, a self-report survey was conducted on nurses working at a university hospital. Among those sent out, 1,201 responded and 851 were used for the final analysis. RESULTS: It was shown that the frequency of gastrointestinal disorders in shift workers was 1.881 times higher than that of non-shift workers. Factors that influenced gastrointestinal disorders included age, marital status, work duration, type of employment, job satisfaction, and perceived health status. Gastrointestinal disorders were seen more often with older age, being married, longer duration of employment, non-regular worker, low job satisfaction, bad perceived health status, and shift works. CONCLUSIONS: To prevent gastrointestinal disorders in nurses who work shifts, a health checkup system should be in place for clinical nurses who are of older age and have longer employment records. To decrease the causes of gastrointestinal disorders, campaigns suggesting regular diet and quitting alcohol use should be held consistently. Also, a category related to gastrointestinal disorders should be added to the employee health checkup for nurses with long work experience.

PURPOSE: The Purpose of this study was to identify the relationship among leadership style of nurse managers, job satisfaction, organizational commitment, and turnover intention. METHOD: The subjects were 468 nurses and 19 head nurses who were working at the 3 general hospitals in seoul. The data were collected from July 6 to September 14, 2001 by the structured questionnaires. For data analysis, descriptive statistics, ANOVA, Pearson correlation coefficient, and stepwise multiple regression with SAS package were used. RESULT: 1) The score of the nurse managers' transformational leadership perceived by surbodinates' were higher than that of the nurse managers' transactional leadership. Among 5 subdimensions of the leadership styles perceived by surbodinates', the scores of 'charisma' and 'intellectual stimulation' were highest and 'management by exception' were lowest. 2) 'Charisma', 'intellectual stimulation', 'individual consideration' and 'contingent reward' were positively related to all of variables except 'turnover intention'. 'Management by exception' was negatively related to all of variables and was positively related to 'turnover intention'. 3) 'Job satisfaction' was positively related to 'organizational commitment' and 'Job satisfaction', 'organizational commitment' were negatively related to 'turnover intention'. 4) As a result of stepwise multiple regression analysis, the key determinants of 'turnover intention' were 'organizational commitment' and this explained 44.4% of the total variance of it.

Purpose: : This study sought to explore intensive care unit (ICU) nurses’ perceptions regarding the disclosure of patient safety incidents (DPSI) and identify the relationship between the perception of DPSI and communication barriers. Methods: : This study used a descriptive research design. A total of 110 ICU nurses from a tertiary hospital were surveyed online between September 14 and October 5, 2022. The mean DPSI score ranged between 1.0 and 4.0, with a higher score indicating a higher perception of DPSI. Results: : The mean score for ICU nurses’ perceptions of DPSI was 2.92 (SD=0.37). Among the characteristics of ICU nurses, differences were observed in perceptions of DPSI according to gender, age, total work experience, and ICU work experience. Communication barriers among ICU nurses were negatively correlated with negative results as a sub-factor of perceptions of DPSI. Ambiguity in the nurse’s position, lack of confidence, differences in perspectives with patients, and inadequate nurse-patient relationships as sub-factors of communication barriers exhibited a negative correlation with negative results as a sub-factor of perceptions of DPSI. Conclusions : ICU nurses’ perceptions of DPSI and the sub-factors related to communication barriers are negatively related to DPSI. To improve ICU nurses’ perceptions, open and non-punitive circumstances, staff education, practical guidelines, and support systems are required.

STATEMENT OF PROBLEM: Recently, resin cements have become more widely used and have been accepted as prominent luting cements. Current resin cements exhibit less microleakage than conventional luting cements. However, the constant contact with water and exposure to occlusal forces increase microleakage even in resin cements inevitably. Most bonding resins have been modified to contain a hydrophilic resin such as 2-hydroxyethylmethacrylate (HEMA) to overcome some of the problems associated with the hydrophobic nature of bonding resins. By virtue of these modifications, bonding resins absorb a significant amount of water, and there may also be significant stresses at bonding interfaces, which may adversely affect the longevity of restorations. Therefore the reinforcement of water stability of resin cement is indispensable in future study. PURPOSE: This study was conducted to examine the influence of water retention on microleakage of two resin cements over the period of 6 months. MATERIALS AND METHODS: 32 ex acted human teeth were used to test the microleakage of a single full veneer crown. Two resin cements with different components and adhesive properties - Panavia F (Kuraray Co., Osaka, Japan) and Super-Bond C&B (Sun Medical Co., Kyoto, Japan)- were investigated. The storage medium was the physiological saline solution changed every week for 1 month, 3 months, and 6 months. One group was tested after storage for 1 day. At the end of the each storage period, all specimens were exposed to thermocycling from 5.C to 55.C of 500 cycles and chewing simulation of 50,000 cycles, and then stained with 50% silver nitrate solution. The linear penetration of microleakage was measured using a stereoscopic microscope at x 40 magnification and a digital traveling micrometer with an accuracy of +/-3 um. Values were analyzed using two-way ANOVA test, Duncan's multiple range tests (DMRT). RESULTS: Statistically significant difference of microleakage was shown in the 3-month group compared with the 1-day or 1-month group in bot systems (p<0.05) and there were statistically significant differences in microleakage between the 3-month group and the 6-month group in both systems (p<0.05). The two systems showed different tendency in the course of increased microleakage during 3 months. In Panavia F, microleakage increased slowly throughout the periods. In Super-Bond C&B, there was no significant increase of microleakage for 1 month, but there was statistically significant increase of microleakage for the next 2 months. For the mean microleakage for each period, in the 3-month group, microleakage of Super-Bond C&B was significantly greater than that of Panavia F. On the other hand, in the 6-month group, microleakage of Panavia F was significantly greater than that of Super-Bond C&B (p<0.05). CONCLUSION: Within the limitation of this study, water retention of two different bonding systems influence microleakage of resin cements. Further studies with the longer observation periods in viro are required in order to investigate water stabilty and the bonding durability of the resin cement.

This was designed to identify the relationship of perceived stress, ways of coping, and stress response in student nurses. The subjects of this study were 320 student nurses from two universities and three junior colleges located in Seoul. The data were collected from November 28 to December 10, 1997 by a questionnaire survey method. The instruments for this study were the perceived stress scale developed by Levenstein(1993), ways of coping scale developed by Lazarus and Folkman(1984), and the stress response scale developed by Choi(1991). The data were analyzed by SAS program, using descriptive statistics, Pearson correlation coefficient, and ANOVA. The results are summarized as follows : 1. The mean score for the level of perceived stress was 2.55. 2. The mean score for the level of problem oriented coping was 1.61 and the mean score for the level of emotional oriented coping was 1.37. 3. The mean score for the level of stress response was 3.74. Stress was classified into nine factors and the order of scoring for the most frequent was; assignments(3.98), as a nurse(3.97), interpersonal relationship(3.88). 4. The relationship between perceived stress and stress response revealed a positive significant correlation(r=0.23, p=0.0001). 5. The relationship between emotional oriented coping and stress response revealed a positive significant correlation(r=0.22, p=0.0001). 6. The relationship between perceived stress and emotional oriented coping revealed a positive significant correlations(r=0.13, p=0.020). In conclusion, this study revealed that the level of perceived stress and ways of coping were important factors influencing the stress response of student nurses. Therefore, in consideration of perceived stress, ways of coping should be included in the development of a stress management program for student nurses. Further research with an expanded area and subjects is recommended.

The study was undertaken to evaluate the effect of major blood components on the CT number. The CT numbers according to the various levels of hematocrit, total protein and cholesterol were checked and analysed by the dilution of pack cell, plasma and 184 complete blood cell count samples under same scanning conditions. In case of normal protein and cholesterol level(33 samples), the CT number was increased about 5.5 hounsfield unit according to 10% increase of hematocrit level: and In case of normal hematocrit and cholesterol level(39 samles), the CT number was increased about 3.5 hounsfield unit according to 1gm% increase of protein level. CT number changes were not predictable according to the changes of cholesterol level(34 samples). From these results, we concluded that major blood components should be considered in the CT number analysis of tissue.

Purpose: Breastfeeding is the optimal method for feeding a newborn. But insufficient breast milk is the major reason why mothers give up breastfeeding. Herbal galactagogues have been used increasingly to treat postpartum hypogalactia. This study examined the effect of an herbal tea containing Chrysanthemum indicum, as the main ingredient, on milk production in lactating rats. Methods: The herbal tea contained C. indicum (27%), Foeniculum vulgare Mill (21%), Pimpinella anisum (18.2%), Carum carvi (16.1%), Urtica dioica (14.7%), and Gardenia jasminoides (3%). Sixteen lactating Sprague-Dawley (SD) rats were divided randomly into 2 groups, the normal control group (NC; n = 8), and the galactagogue herbal tea group (GHT; n = 8) for 7 days. Lactating rats were administered the decoction of an herbal galactagogue mixture by oral gavage or the same amount of distilled water and milk production was assessed by measuring the pups' weights during the suckling period. The blood concentrations of prolactin, cortisol, oxytocin levels and mammary gland tissues were examined to assess the effects of the galactagogue. Results: Milk production was 9.2% higher in the GHT group given the herbal tea than in the NC group and the difference was statistically significant. The cortisol level in the GHT group was 17.2% higher than the NC group. The herbal tea containing C. indicum increased the size of the alveoli epithelium cells and the mammary lobe. Conclusion The present study revealed the potential of herbal tea containing C. indicum to enhance milk production in postpartum SD rats.
