This study examined the effects of the abdominal drawing-in (ADI) maneuver using a pressure biofeedback on muscle recruitment pattern of erector spinae and hip extensors and anterior pelvic tilt during hip extension in the prone position. Fourteen able-bodied volunteers, who had no medical history of lower extremity or lumbar spine disease, were recruited for this study. The muscle onset time of erector spinae, gluteus maximus, and medial hamstring and angle of anterior pelvic tilt during hip extension in prone position were measured in two conditions: ADI maneuver condition and non-ADI maneuver condition. Muscle onset time was measured using a surface electromyography (EMG). Kinematic data for angle of anterior pelvic tilt were measured using a motion analysis system. The muscle onset time and angle of anterior pelvic tilt were compared using a paired t-test. The study showed that in ADI maneuver during hip extension in prone position, the muscle onset time for the erector spinae was delayed significantly by a mean of 43.20 ms (SD 43.12), and the onset time for the gluteus maximus preceded significantly by a mean of -4.83 ms (SD 14.10) compared to non-ADI maneuver condition (p<.05). The angle of anterior pelvic tilt was significantly lower in the ADI maneuver condition by a mean of 7.03 degrees (SD 2.59) compared to non-ADI maneuver condition (15.01 degrees) (p<.05). The findings of this study indicated that prone hip extension with the ADI maneuver was an effective method to recruit the gluteus maximus earlier than erector spinae and to decrease anterior pelvic tilting.

Purpose: This study aimed to identify the relationships among physical symptoms, activities of daily living, and health-related quality of life (HRQoL) in community-dwelling older adults. Methods: A stratified random sampling method was conducted to recruit participants from May 10 to August 17, 2007. Physical symptoms were measured using the Physical Health Questionnaire (PHQ), activities of daily living using the Late-Life Functional and Disability Instrument (LLFDI), and HRQoL using the Medical Outcomes Short-Form Health Survey (SF-36) in 242 community-dwelling elderly Korean people. Results: The HRQoL correlates with the physical symptoms (r=-.31) and the function component (r=.59). Of the two disability parts of the LLFDI, the limitation dimension correlates higher (r=.57) with HRQoL than the frequency dimension (r=.42). The HRQoL is significantly associated with the function component, and disability limitation in capability which explained 44.4% of variance in physical health. Conclusion: These results may contribute to a better understanding of physical symptoms, activities of daily living, and HRQoL in community-dwelling older adults. Therefore, health programs for prompting older adult's health should be planned based on results of the study.

Purpose: The purpose of this study is to analyze how the experiences of nurses influence their role model function when they are mothers of children who in turn have become nurses or nursing students. Method: The subjects of this study were 12 nurses, 8 of their children who became nurses and another 4 children then in training to become one. Data were collected through in-depth personal interviews and subsequently analyzed through a phenomenological approach. Results: Four main themes were identified as follows; 'Persuasion and dissuasion,' 'Proud but still pathetic,' 'As mom and senior nurse' and 'Great to pass it down.' Conclusion: The results of this study show that the nurse as mother could be a positive professional role model for her children. However, they tended to stress the arduous clinical routines and poor work conditions nurses currently experience. Should such routines and conditions improve, mothers who are nurses would be more willing to recommend the nursing profession to their children. Improving the professional environment is thus important because intergeneration nursing mobility provides a reliable resource to recruit qualified and dedicated nursing personnel.

Purpose : Nurses' knowledge regarding advance directives may affect their administration of and confidence towards end of life care. This study aimed to describe the relationships of knowledge, confidence, and learning needs with advance directives among hospital nurses. Method : This cross-sectional study was performed at a tertiary university hospital in Seoul between September 25 and October 14, 2017. Convenience sampling was used to recruit nurses who provided bedside care and had at least 1 year of clinical experience. We used a validated self-report questionnaire. Results : The mean score of knowledge, confidence and learning needs were $5.00{\pm}1.73$, $29.81{\pm}7.52$, and $64.54{\pm}8.48$ respectively. Hospital nurses' knowledge, confidence and learning needs were significantly different according to age, job position, educational level and perceived advance directives. Knowledge regarding advance directives was significantly associated with confidence (r = .27, p < .001) and learning needs (r = .16, p = .005). Conclusion : Knowledge regarding advance directives was relatively low compared to the findings of previous studies. Therefore, nurses should be knowledgeable and encouraged to initiate advance directives. It is necessary to develop a standardized educational program regarding advance directives based on Korean cultures.

Background: Radiation-induced pneumonitis and pulmonary fibrosis are common dose-limiting complications in patients receiving radiotherapy for lung, breast, and lymphoid cancers. In this study, we investigated the characteristics of effective immune cells related to pneumonitis and fibrosis after irradiation. Materials and Methods: After anesthesia, the whole thorax of C57BL/6 mice was irradiated at 14 Gy. The lung tissue and bronchoalveolar lavage fluid were collected at defined time points post-irradiation for the determination of histological and immunohistochemical analysis and inflammatory cell population infiltrated into the lung. Results and Discussion: Whole thoracic irradiation increased the deposition of extracellular matrix (ECM), lung weight, and pleural effusions, which started to die from 4 months later. At 4 months after irradiation, the numbers of macrophages and lymphocytes as well as neutrophils were increased dramatically in the lung. Interestingly, the macrophages that were recruited into the lung after irradiation had an enlarged foamy morphology. In addition, the expressions of chemokines (CCL-2, CCL-3, CXCL-10) for the attraction of macrophages and T cells were higher in the lung of irradiated mice. The high expressions of these chemokines were sustained up to 6 months following irradiation. In thoracic irradiated mice, infiltrated macrophages into the lung had the high levels of Mac-3 antigens on their surface and upregulated the hallmarks of alternatively activated macrophages such as arginase-1 and CD206. Furthermore, the levels of IL-4 and IL-13 were higher in a BAL fluid of irradiated mice. Conclusion: All results show that thoracic irradiation induces to infiltrate various inflammation-related immune cells, especially alternatively activated macrophages, through enhancing the expression of chemokines, suggesting that alternatively activated macrophages are most likely important for leading to pulmonary fibrosis.

Escherichia coli, which harbored the ars operon from a plasmid pMH12 of Klebsiella oxytoca D12, showed filamentation due to the expression of ars genes in the presence of arsenite. The continued DNA replication in the absence of cell division was revealed, since nucleoids abound with DAPI appeared to be arranged in chains. In contrast to overexpression of arsA, its frame-shift mutant and knock-out mutant lost filamentation in the presence of arsenite, which suggested that ars-induced division block was dependent on expression of arsA. ArsA-induced division inhibition was not a consequence of an inhibition of DNA replication, and the inability of arsenite to induce an SOS response indicated that arsA-mediated division inhibition was dependent on the expression of the gene product encoded by the minB operon. ArsA is a peripheral membrane protein with an ATP-binding domain, which is homologous to MinD that requires ATP-dependent efflux. These results suggested that ArsA could possibly recruit MinC to the membrane and modulate cytoplasmic FtsZ to block assembly at the middle of the cell.
