Background: Atrial fibrillation (AF) is the most common type of cardiac arrhythmia. Totally thoracoscopic ablation (TTA) is a surgical treatment showing a high success rate as a hybrid procedure with radiofrequency catheter ablation to control AF. This study compared the early complications of warfarin and non-vitamin K antagonist oral anticoagulants (NOACs) in patients who underwent TTA. Methods: This single-center retrospective cohort study enrolled patients who underwent planned TTA for AF from February 2012 to October 2020. All patients received postoperative anticoagulation, either with warfarin or a NOAC (apixaban, rivaroxaban, dabigatran, or edoxaban). Propensity score matching was performed for both groups. Early complications were assessed at 12 weeks after TTA and were divided into efficacy and safety outcomes. Both efficacy and safety outcomes were compared in the propensity score-matched groups. Results: Early complications involving efficacy outcomes, such as stroke and transient ischemic attack, were seen in 5 patients in the warfarin group and none in the NOAC group. Although the 2 groups differed in the incidence of efficacy outcomes, it was not statistically significant. In safety outcomes, 11 patients in the warfarin group and 24 patients in the NOAC group had complications, but likewise, the between-group difference was not statistically significant. Conclusion: Among patients who underwent TTA, those who received NOACs had a lower incidence of thromboembolic complications than those who received warfarin; however, both groups showed a similar bleeding complication rate. Using a NOAC after TTA does not reduce efficacy and safety when compared to warfarin.

Of actinomycetes isolated from volcanic compost soils, 115 representative strains which showed distinctive morphologicla features were numerically classified, compared with reference strains of Streptomyces. One hundred and twenty unit characters were tested and the average probability of error was 4.27%. The cluster analysis resulted in two groups: group A included strains of actinomycetes except streptomycetes. Group A was divided into 2 major clusters (over 5 strains), 10-diaminopimelic acid. Group B was divided into 5 clusters, of which 4 clusters contained mesodiminopimelic acid and 1 cluster LL-diaminopimelic acid. The major clusters of group A showed higher abilities of substrate utilization and degradation, and higher resistance to inhibitors, whereas the minor and single member clusters of group A showed relatively higher antimicrobial activities. On the other hand, all clusters of group B showed relatively lower abilities of substrate utilization and degradation and lower resistance to inhibitors.

Purpose: The purpose of this study was to evaluate the efficacy of applying a defecation encouragement program for patients undergoing total knee replacement arthroplasty (TKRA). Methods: This program was based on the nursing best practice guideline: prevention of constipation in the older adult population by the National Guideline Clearing House (NGC) in 2011, which included fluid intake, bowel training, and abdominal and pelvic floor exercises. A team of one orthopaedic clinical nurse specialist and six orthopaedic nurses with a 10 years of clinical experience applied and assisted patients with the program. Formal counsel was provided by one orthopaedic doctor, one gastroenterologist, and one exercise therapist. Patients who defecated one day prior to or on the day of TKRA surgery were included. Data collected from 72 subjects were analyzed using SPSS/WIN 21.0. Results: Time until first defecation after surgery was 2.4±1.1 days in experimental group, which was significantly shorter than the 3.5±0.9 days in control group (t=4.28, p<.001). Constipation assessment scale showed significantly lower points (t=2.55, p=.013) in experimental group (1.3±1.2) compared to control group (2.6±2.6). The experimental group and control group were 17.3±7.67 and 23.7±14.43, respectively, and the experimental group used less laxatives (t=2.83, p=.021). Conclusion: A defecation encouragement program was proved to be an appropriate nursing intervention for patients undergoing TKRA. This study confirmed that constipation is a nursing problem that can be sufficiently prevented if nurses are interested and encourage defecation.

This paper aims to investigate the microstructural evolution and mechanical properties of hot-deformed AlMg4 alloys with Mn, Fe, and Si as the main impurities. For this purpose, solidification behavior and microstructural evolution during hot-rolling and heat-treatment processes are investigated by using theoretical calculations and experimental characterization. The crystallization and morphological transformation of intermetallic Al₃Fe, Al₆Mn, and Mg₂Si phases are revealed and discussed in terms of the variation in chemical composition. Following a homogenization heat-treatment, the effect of heat treatment on the intermetallic compounds is also investigated after hot-rolling. It was revealed that the Mg₂Si phase can be broken into small particles and spherodized more easily than the Al₃Fe intermetallic phase during the hot-rolling process. For the Mn containing alloys, both yield and ultimate tensile strength of the hot-rolled alloys increased from 270 to 296 MPa while elongation decreased from 17 to 13%, which can be attributed to Mn-containing intermetallic as well as dispersoid.

This study was done about 371 tuberculosis(TB) patients composed 195 newly registered at Kyungju Gun Health Center from May 1989 to April 1990 (Group A) and 176 being treated at hospitals or private clinics from January 1988 to November 1989(Group B). When Group A patients visited and newly registered at Health Center, data was obtained by interviewing with a prepared questionnaire paper. And well trained inquirer visited Group B patients and obtained data by the same method from February 1990 to April 1990. The results are as follows ; Group A was generally lower than Group B in socioeconomic status and in family history of TB, the rate of Group A was 24.1% and higher than 11.9% in Group B(p<0.05). Knowledge about TB was improved more than past, but those who answered that TB is 'a communicable disease' were 59.5% in Group A and 51.7% in Group B(p<0.05). Those answered that TB is 'a inherited disease' were 9.2% and 11.4% each. And 1.7% of Group B answered that TB is 'a incurable disease'. Knowledge about TB treatment also was improved more than past, but in the rate of those who answered that TB is a curable disease provided by well treatment Group B(77.8%) was worse than Group A(91.3%). The rate of those who answered that TB were been able to cure by regularly anti-TB medication were 98.0% in Group A and 89.8% in Group B. Its difference was statistically significant. The rate that patients took the first diagnosis and wanted to receive treatments at the same organ were 34.9% of Group A at Health Center and 72.2% of Group B at hospitals or private clinics. And its difference was statistically significant. In the reasons that Group B knew Health Center treated pulmonary TB but they was treated at hospitals or private clinics, unreliability to Health Center was 48.1%. The reasons that Group A was treated at Health Center were 'because of trust' 63.1%, 'because of low cost' 50.3%, 'because of low cost except trust' 9.3%, 'no specific reasons' 27.7%. In the courses of knowing that TB was controlled at Health Center, 'by neighborhood, health worker and doctors' were 84.9% in Group A and 69.0% in Group B. But 'by TV or radio' were 8.2% in Group A and 14.7% in Group B, 'by school education' 2.5% in Group A and 6.2% in Group B. Conclusively, Group A patients were lower than Group B in socioeconomic status, but better than in knowledge about TB. Its reasons was suggested that Health Center had controlled TB patients better than hospitals and private clinics. But considering, that difference in the rate of the same organ for the first diagnosis and treatment, that the only 63.0% of Group A have treated due to 'reliability to Health Center', and that 48.1% of Group B knew that Health Center treated pulmonary TB but didn't visit it due to 'unreliability to Health Center', that public relations(PR) about use Health Center for pulmonary TB and health education for TB was thought to have to strengthened.

Purpose: The purpose of this study was to examine the effect of absolute bed rest(ABR) on occurrence of bleeding, discomfort and back pain after kidney biopsy. Method: This study was the nonequivalent control group posttest design. The experimental group was allowed to stay in beds for 18 hour-bed rest(BR) after 6 hour-ABR while the control group was allowed to stay ABR for 24 hours. Results: No bleeding sign was showed for all the patients. Discomfort of voiding, eating, ABR in the control group appeared at a higher level. Three subjects in the control group needed nelaton catheterization, whereas no catheterization was required in the experimental group. There was no significant difference in back pain. However, the control group used more pain killer with significant difference. From these results. Conclusion: There was no significant correlation between ABR time and bleeding. On the other hand, the discomfort of the experimental group appeared at a lower level by reducing ABR time. Therefore, Reduction of ABR time after kidney biopsy would be more efficient way for patients.

As this study is the descriptive research study that tries to present the basic data aiming to establish a role of nurses for the Community Welfare Center, by surveying the role expectation and the degree of role performance towards nurses for the Community Welfare Center that nurses for the Community Welfare Center and social workers recognize, it carried out the Questionnaire research targeting nurses who are working for the Community Welfare Center located in Seoul and social workers of institutions where nurses are working, and then analyzed the results, and the study results are as follows. Both the group of nurses and the group of social workers were highly recognizing the necessity and the importance of nurses for the Community Welfare Center, and expected that more effective services will be possible to be offered by means of that nurses do work for the Community Welfare Center. However, compared to the degree that social workers recognize a nurses specialty, the nurses thought that their specialty is not acknowledged in the Community Welfare Center, and even in case of duty friction between groups being felt while social workers and nurses are working together, nurses were experiencing further friction of duties. While nurses are well recognizing their roles, they are statistically and significantly recognizing the degree of role performance lower than expected, thus the difference between the role expectation and the role performance could be seen. Also, the group of nurses showed the higher role expectation towards nurses than the group of social workers, and in relation to roles of a counselor, referral resource, an advocator, an educator, a case manager, a and a coordinator, the degree of role expectation by the group of nurses is statistically and significantly higher than the group of social workers, thus it could be seen that there is difference in the expectation degree between both groups, as to a role of nurses for the Community Welfare Center. In particular, as to a role of universally medical services, the expectations between nurses and social workers showed mutual agreement, but in relation to a role of nurses for community in the more expanded sphere, social workers did not show a receptive attitude, thus it was indicating that there exists an element of role conflict. In relation to the role performance of nurses for the Community Welfare Center, nurses were feeling the disorder degree more than social workers, in all items of disorder factors, and there was difference in recognition between nurses and social workers, as to the priority of disorder factors. Because of, through this study, having been found the difference in recognition of role expectation, the degree of role performance, and a disorder factor between nurses and social workers, as to the nurses for the Community Welfare Center, it is required a study with a more diversified method on a role of nurses for the Community Welfare Center.

Purpose: The purpose of this study was to evaluate the effect of abdominal massage on alleviating pain caused by the injection of recombinant gonadotropin for In Vitro Fertilization (IVF) among infertile women. Methods: This study employed a nonequivalent control group non-synchronized design. A total sample of 149 infertile women who never experienced in vitro fertilization was recruited at C fertility center. Seventy women were assigned into experimental group and 79 into controls. The experimental group had been informed to do abdominal massage prior to the injection and to record their subjective pain using visual analogue scale. The control group had been informed to record their subjective pain in the same way just after the injection. Results: Compared to the pre-tested pain scores, the pain scores in experimental group were significantly reduced by 0.7 points, whereas the control group increased by 0.9 points (t=-4.55, p=.001). Conclusion: This study confirms that the use of abdominal massage prior to the injection is an effective way to alleviate pain on injection site. This massage may be a useful intervention for infertile women about pain alleviation.

Objective: To evaluate the ability of serum anti-M$\ddot{u}$llerian hormone (AMH), FSH, and age to clinically predict ovarian response to controlled ovarian hyperstimulation (COH) in IVF patients with endometriosis. Methods: We evaluated 91 COH cycles, including 43 cycles with endometriosis (group I) and 48 cycles with male factor infertility (group II) from January to December, 2010. Patients were classified into study groups based on their surgical history of endometriosis-group Ia (without surgical history, n=16), group Ib (with a surgical history, n=27). Results: The mean age was not significantly different between group I and group II. However, AMH and FSH were significantly different between group I and group II ($1.9{\pm}1.9$ ng/mL vs. $4.1{\pm}2.9$ ng/mL, $p$ <0.01; $13.1{\pm}7.2$ mIU/mL vs. $8.6{\pm}3.3$ mIU/mL, $p$ <0.01). Furthermore, the number of retrieved oocytes and the number of matured oocytes were significantly lower in group I than in group II. In group II, AMH and FSH as well as age were significant predictors of retrieved oocytes on univariate analysis. Only the serum AMH level was a significant predictor of poor ovarian response in women with endometriosis. Conclusion: Serum AMH may be a better predictor of the ovarian response of COH in patients with endometriosis than basal FSH or age. AMH level can be considered a useful clinical predictor of poor ovarian response in endometriosis patients.
