3.Ecological Correlates of Cardiovascular Disease Risk in Korean Blue-collar Workers: A Multi-level Study.
Journal of Korean Academy of Nursing 2015;45(6):857-867
PURPOSE: The purpose of this study was to investigate individual and organizational level of cardiovascular disease (CVD) risk factors associated with CVD risk in Korean blue-collar workers working in small sized companies. METHODS: Self-report questionnaires and blood sampling for lipid and glucose were collected from 492 workers in 31 small sized companies in Korea. Multilevel modeling was conducted to estimate effects of related factors at the individual and organizational level. RESULTS: Multilevel regression analysis showed that workers in the workplace having a cafeteria had 1.81 times higher CVD risk after adjusting for factors at the individual level (p =.022). The explanatory power of variables related to organizational level variances in CVD risk was 17.1%. CONCLUSION: The results of this study indicate that differences in the CVD risk were related to organizational factors. It is necessary to consider not only individual factors but also organizational factors when planning a CVD risk reduction program. The factors caused by having cafeteria in the workplace can be reduced by improvement in the CVD-related risk environment, therefore an organizational-level intervention approach should be available to reduce CVD risk of workers in small sized companies in Korea.

Journal of the Korean Surgical Society 2000;58(5):656-660
PURPOSE: The purpose of this study was to analyze the clinical features and to assess the risk factors in the treatment of small-bowel obstructions. METHODS: This retrospective clinical report was based on the medical records of 67 patients who were treated between Jan. 1992 and Dec. 1999 and who had had a history of abdominal surgery due to cancer. RESULTS: The distribution of primary cancer was as follows: stomach cancer 36 (53.7%), colorectal cancer 25 (37.3%), uterine and ovarian cancer 4 (6.0%), and other cancers 2 (3.0%). The mean interval from the primary operation to the development of a small- bowel obstruction was 27 months. Conservative treatment produced a successful outcome in 36 patients (59.0%), but recurrences of obstruction were noted in 18 of those patients. There were 34 operations in 30 patients. The initial success rate of operative treatment was 80% (24/30), obstructions recurred in 6 patients. The causes of obstructions in the surgically treated patients were adhesion (53.3%) and recurrence of cancer (46.7%). The postoperative complication rate was 44.1%, and the mortality rate was 20.0%. The mean survival time of the patients with benign causes of obstruction was significantly longer than that of the patients with malignant causes of obstruction (46 months vs 11 months). CONCLUSION: In the treatment of such patients, conservative treatment should be considered first. However if conservative treatment fails, surgery should be done without hesitation, especially in patients with no definite evidence of recurrence.

5.Factors Affecting Health-related Quality of Life on Korean Blue-collar Workers.
Korean Journal of Occupational Health Nursing 2015;24(2):94-102
PURPOSE: The purpose of this study was to investigate Korean blue-collar workers' Health-related Quality of Life (HRQoL) and influencing factors in Korean blue-collar workers. METHODS: Participants in this study were 109 Korean blue-collar workers. The survey included health-related, work-related, and psycho-social factors. SF-36 was used to measure HRQoL. The data were analyzed using Pearson's correlation, and hierarchical multiple regression analysis. RESULTS: In the hierarchical linear regression model, when subjects' psycho-social variables were included in the regression model, R2 change was statistically significant. The significant predictors for HRQoL were education level (beta=.26, p=.023), depression (beta=-.38, p<.001), and self-efficacy (beta=.23, p<.001). CONCLUSION: The results of this study indicate that health care providers must have priority to consider psycho-social variables, especially depression and self-efficacy to improve HRQoL in Korean blue-collar workers.

For the purpose of morphologic analysis of human cytomegalovirus (HCMV) antigens reacting with specific monoclonal antibodies, we observed HCMV particles after immunogold staining. HCMV was cultured in human fetal lung fibroblasts to be concentrated by polyethylene glycol 6,000. The HCMV stock was dropped onto Formva-coated grids and was fixed by 2% glutaraldehyde. The grids were reacted with MCMVA57, 93, 135 or with SCMVM1, 6, 14, 49 monoclonal antibodies (MoAbs) follwed by gold (10 nm)-conjugated goat anti-mouse IgG. Then the grids were stained with 2.5% uranyl acetate to be observed under Hitachi 500 or Jeol 1,200 electron microscope. When HCMV was reacted with SCMVM14 and SCMVM49 MoAbs, gold particles were adsorbed to virion envelopes, suggesting that the reactive antigens were envelope proteins. In cases of MCMVA135 and SCMVM6 MoAbs, gold particles were adsorbed to dense bodies as well as to virion envelope. These results, together with the previous results of immunologic and genetic characterization, suggested that the reactive antigens of MCMVA135 and SCMVM6 MoAbs were gB homologue and structural protein, respectively. In case of SCMVM1 MoAb, gold particles were adsorbed to capsids, envelopes, and dense bodies, suggesting that the reactive antigen was structural protein. In case of SCMVM8 MoAb, gold particles were observed between the envelopes and capsids, which space was supposed to be the tegument, suggesting that the reactive antigen was carbohydrate moiety of glycoprotein or its polymer. In cases of MCMVA57 and MCMVA93 MoAbs, gold particles were adsorbed to only dense bodies, suggesting that the reactive antigens were precursors of structural proteins.

7.End-of-Life Care for End-stage Heart Failure Patients
Korean Circulation Journal 2022;52(9):659-679
Efforts to improve end-of-life (EOL) care have generally been focused on cancer patients, but high-quality EOL care is also important for patients with other serious medical illnesses including heart failure (HF). Recent HF guidelines offer more clinical considerations for palliative care including EOL care than ever before. Because HF patients can experience rapid, unexpected clinical deterioration or sudden death throughout the disease trajectory, choosing an appropriate time to discuss issues such as advance directives or hospice can be challenging in real clinical situations. Therefore, EOL issues should be discussed early. Conversations are important for understanding patient and family expectations and developing mutually agreed goals of care. In particular, high-quality communication with patient and family through a multidisciplinary team is necessary to define patient-centered goals of care and establish treatment based on goals. Control of symptoms such as dyspnea, pain, anxiety/ depression, fatigue, nausea, anorexia, and altered mental status throughout the dying process is an important issue that is often overlooked. When quality-of-life outweighs expanding quantity-of-life, the transition to EOL care should be considered. Advanced care planning including resuscitation (i.e., do-not resuscitate order), device deactivation, site for last days and bereavement support for the family should focus on ensuring a good death and be reviewed regularly. It is essential to ensure that treatment for all HF patients incorporates discussions about the overall goals of care and individual patient preferences at both the EOL and sudden changes in health status. In this review, we focus on EOL care for end-stage HF patients.
8.Effectiveness of the Infectious Disease (COVID-19) Simulation Module Program on Nursing Students: Disaster Nursing Scenarios
Journal of Korean Academy of Nursing 2021;51(6):648-660
Purpose:
This study aimed to develop an emerging infectious disease (COVID-19) simulation module for nursing students and verify its effectiveness.
Methods:
A one-group pretest–posttest quasi-experimental study was conducted with 78 under-graduate nursing students. A simulation module was developed based on the Jeffries simulation model. It consisted of pre-simulation lectures on disaster nursing including infectious disease pandemics, practice, and debriefings with serial tests. The scenarios contained pre-hospital settings, home visits, arrival to the emergency department, and follow-up home visits for rehabilitation.
Results:
Disaster preparedness showed a statistically significant improvement, as did competencies in disaster nursing. Confidence in disaster nursing increased, as did willingness to participate in disaster response. However, critical thinking did not show significant differences between time points, and neither did triage scores.
Conclusion
The developed simulation program targeting an infectious disease disaster positively impacts disaster preparedness, disaster nursing competency, and confidence in disaster nursing, among nursing students. Further studies are required to develop a high-fidelity module for nursing students and medical personnel. Based on the current pandemic, we suggest developing more scenarios with virtual reality simulations, as disaster simulation nursing education is required now more than ever.

PURPOSE: This study was conducted to identify subjective attitudes towards terminal patients in nursing students who had clinical practice. The types of subjective attitude were classified by applying Q methodology. According to those types, basic reference data for the development of educational programs were provided.METHODS: Thirty-four final Q samples were selected, and Q classification with a nine-point scale was performed with P samples of 43 nursing students. A key factor analysis was conducted with the collected data using the PC QUANAL program.RESULTS: Nursing students' attitudes towards terminal patients were grouped into three types. The total variable was 49.96%. Students with Type 1 (“wish for life-sustaining medical treatment”) thought that terminal patients accurately understood their medical condition and wanted to prolong their lives. Others with Type 2 (“need for service and support”) believed that a multidisciplinary nursing system needs to be established to help terminal patients prepare for death. Students with Type 3 (‘awareness and acceptance of death’) thought that terminal patients wanted to die with dignity at a hospice unit.CONCLUSION: This study analyzed various types of attitude towards terminal patients, as perceived by nursing students with clinical training experience. Development of educational programs for each attitude type analyzed in this study could contribute to systematic training programs for nursing students caring for terminal patients.

The purpose of this study was to evaluate the effectiveness of gargling solution with 0.05% NaF and 10% Xylitol in orthodontic patients with fixed appliance. The sample consisted of 30 adolescent patients who were classified into an experimental group and a control group, 15 patients each. Experimental group was used experimental gargling solution and the control group was used with placebo solution. The change of S. mutans in saliva was observed by Cariescreen(R) SM kit at pre and post 2, 4, 6, 8 weeks. The results were as follows. 1. There were significant reduction in the number of S. mutans in saliva between pre and post 2 weeks(p<0.01), 4 weeks(p<0.05), 6 weeks(p<0001), and 8 weeks(p<0001) in experimental group. And significant reduction also were observed in the number of Ss mutans in saliva between post 2 weeks, 6 weeks(p<0.05), and 8 weeks(p<0.05), but no significant reduction were showed in control group. 2. There were significant correlation in the number of S. mutans between each measurement time(pre and post 2, 4, 6, 8 weeks) in control group. 3. There weee no correlation between pre and post 2 weeks, but significant correlation were observed between 2, 4, 6, 8 weeks in experimental group.
