PURPOSE: The purpose of this study was to examine the adherence to physical activity (PA) among older adults in Korea using data from the Fourth Korean National Health and Nutrition Examination Survey (KNHANES IV), and to illustrate geographic variations in PA using Geographic Information Systems (GIS). METHODS: A secondary analysis of the KNHANES IV data from 2007 to 2008 was used for this study. Participants of the study included 2,241 older adults over the age of 65. Estimates on adherence to PA were obtained for vigorous, moderate, walking, strengthening, and stretching activities. All estimates were weighted to represent Korean population. The association between participants' characteristics and PA was analyzed using Wald chi-square test. Maps depicting regional variations in PA were created using GIS software. RESULTS: Adherence to PA among Korean older adults who met national recommendations during the period of year 2007-2008 was about 9% in vigorous activity, 10% in moderate activity, and 48% in walking. The most common type of PA was walking. A higher level of PA was associated with male gender, younger age, high level of income and education, and living with family. CONCLUSION: The majority of older adults did not meet the national PA recommendations, suggesting that consistent surveillance and intervention for PA in the geriatric population are needed in the future. Maps generated using GIS visually showed regional differences in PA among the study participants.

2.Hospice-Palliative Care Nurses' Knowledge of Delirium, Self-Efficacy and Nursing Performance on Delirium.
Korean Journal of Hospice and Palliative Care 2018;21(2):65-74
PURPOSE: The aim of this study is to examine the relationships among hospice-palliative care (HPC) nurses' knowledge of delirium, self-efficacy and nursing performance. METHODS: This study was participated by 174 nurses working in the HPC unit. The nurses were asked to fill out a questionnaire that was structured to measure their knowledge of delirium, a self-efficacy in clinical performance scale (SECPS) and nursing performance. RESULTS: The mean score for knowledge was 32.83 out of 45, with correction rate of 73%. The mean score for self-efficacy was 7.08 out of 10. The mean score of nursing performance was 2.95 out of 4. Significant correlation was observed among the variables of knowledge (r=0.28, P < 0.001), self-efficacy (r=0.51, P < 0.001) and nursing performance. CONCLUSION: Nurses with high level of knowledge of delirium showed high level of self-efficacy, and consequently better HPC nursing performance. It is necessary to develop a training program on delirium considering nurses' needs of knowledge of the condition. The effectiveness of the training program should be also examined in future.

To define the basic sequential events of the healing process in normal fracture and evaluate the role of growth regulatory molecules and extracellular matrix components, the expression of transforming growth factor β(TGF-β), platelet-derived growth factor(PDGF), type I and II collagen, and chemistry during the healing process of an experimental fracture of tibia in 41 adult rats for 7 weeks using ABC methods. The phases of inflammation, reparation, and remodeling followed each other in sequence. The inflammatory phase was characterized by hemorrhage, edema, and infiltration of inflammatory cells on the first day. During the reparative phase, the undifferentiated mesenchyme undergoes rapid chondrogenesis, followed by endochondral ossification and supplemented by appositional bone formation. At day 3, the expression of TGF-β and PDGF was noted in the undifferentiated mesenchymal cells and from day 5, these two growth factors were detected in the osteoblasts and extracellular matrix in areas of endochondral ossification and newly formed periosteal bone. From day 3, the expression of type I collagen and osteonectin was noted in the osteoblasts and extracellular matrix in both endochondral ossification and appositional bone growth as a marker of ossification. From day 3, type III collagen was mainly expressed in the plump mesenchymal cells showing chondroid differentiation and chondroid matrix as a marker of cartilaginous reparative phase. From day 14, these growth factors and extracellular matrix components were decreased in staining intensity and at the 5th week, the histology and immunostaining pattern were similar to the mature bone.

Macrophage accumulation has been recognized as a feature of allograft rejection, however, the role of macrophages in rejection remains underappreciated. Macrophages are present within graft tissues throughout the lifespan of the graft, including acute rejection episodes. Recent advances in macrophage biology have demonstrated that different types of macrophages in grafts serve a range of functions, including promotion or attenuation of inflammation, participation in innate and adaptive immune responses, and mediation of tissue injury, fibrosis, and tissue repair. Macrophages contribute to both the innate and acquired arms of the alloimmune response, and, thus, may be involved in all aspects of acute and chronic allograft rejection. Macrophages are also involved in hyperacute and acute vascular rejection of xenografts. A deeper understanding of how macrophages accumulate within grafts and of the factors that control differentiation and function of these cells could lead to identification of novel therapeutic targets in transplantation.

5.Do lifestyle factors influence risk of breast cancer recurrence in Korean women?: a cross-sectional survey
Korean Journal of Women Health Nursing 2022;28(2):145-153
Purpose:
This study aimed to investigate the influencing factors of breast cancer recurrence by comparing the risk factors and lifestyle patterns related to breast cancer in Korean women with and without recurrence.
Methods:
This cross-sectional survey comprised 241 Korean women diagnosed with breast cancer who had received follow-up treatment. Participants were recruited from a university hospital in Seoul and an online social media platform for breast cancer patients. Data were collected either via online or a paper survey, using a structured questionnaire that included general and disease-related characteristics and lifestyle behaviors. Data were analyzed using descriptive statistics, univariate analysis, and logistic regression.
Results:
Recurrence of breast cancer was influenced by four factors; childbirth experience, consumption of green/yellow vegetables, drinking behavior, and recovery from fatigue after sleep. Prevalence of recurrent breast cancer was associated with no childbirth experience (OR=2.29, p=.010), fewer green/yellow vegetables (OR=0.71, p=.008), drinking behavior (OR=0.24, p=.001), and a lower level of recovery from fatigue after sleep (OR=0.51, p<.001).
Conclusion
Aside from having experienced childbirth, this study identified several modifiable factors that influence breast cancer recurrence. Increasing green/ yellow vegetable intake, alleviating fatigue, and reducing alcohol intake are important. Intervention strategies in clinical research and practice can be applied to address risk factors and reduce the prevalence of recurrent breast cancer.

Organ transplantation is limited by the shortage of human organs. Many studies have sought to overcome this hurdle by using animal organs. Porcine organs, especially from miniature pigs, have been used for organ xenotransplantation rather than nonhuman primates. While the molecular profiling for transplantation is well known in humans and rodents, the situation for pigs is almost completely unknown. The present study examined protein regulation of the developing stages of the pancreatic proteome (4 day-old miniature neonate, 19 day-old miniature piglet, and 14 month-old miniature adult pigs) using two-dimensional gel electrophoresis and matrix assisted laser desorption/ionization-time of flight mass spectrometry. Thirteen different expressed spots were observed and nine were identified. The data presented within this study provides critical direction relating to the development of pancreas of miniature pigs, which will assist future proteome analysis of the pancreas, and advance our understanding of the hurdles facing xenotransplantation.

Due to the shortage of human organ donors for transplant, various studies of xenotransplantation, or the use of animal organs instead of human organs, have been carried out. The organs of porcine are thought to be safer and of a more suitable size for xenotransplantationthan those of nonhuman primates. Understanding the levels of expression of proteins, and their post-translational regulation, would be very practical between different species and among developing stages, though the molecular profiling for xenotransplantation has been rarely studied for porcine, while that of human and rodent is well known. Here, in this present study, we report protein regulation of the developing stages of liver (4-day old neonate, 19-day old piglet and 14-month old adult miniature pigs) using 2-DE and MALDI-TOF. From images of the three different stages, a total of 8 spotswhich were differently regulated were identified, and 5 spots were identified with MALDI-TOF MS. The data presented within this study provides critical direction relating to the development of livers of miniature pigs, which will assist future proteome analysis of the liver, and advance our understanding of the hurdles facing xenotransplantaion.

Metastatic tumors to the heart are far more frequent than primary tumors of the heart. Cardiac metastasis may be detected up to 30 percent of patients with fatal lung cancers. Metastatic cancer to the heart is difficult to suspect. Where cardiac metastasis is diagnosed ante-mortem, signs and symptoms of the primary cancer are usually the presenting features and the presence of cardiac involvement is often incidentally detected. We experienced a case of 35-year-old woman with metastatic lung cancer invading the left atrium via pulmonary vein, which was not proved pathologically. She presented with hemoptysis and chest pain. Transthoracic echocardiography demonstrated massive cardiac infiltration with tumor and decreased cardiac wall motion, correlating with the chest CT findings, which were also remarkable for the presence of intracardiac mass and direct invasion to adherent pericardium, pulmonary vein and left atrium. We suggest that careful examination of 2D echocardiography can be noninvasive and valuable tool for diagnosis of metastatic cancer to the heart.

PURPOSE: The purpose of this study was to evaluate the effects of a newly developed Introduction to Clinical Nursing (ICN) program on critical thinking skills, communication competence, self-efficacy, and clinical performance self-confidence in nursing students in their third year. METHODS: One group pre-test and post-test design was used with three data collection time points (pre-test, post-test1 and post-test2). Participants were 74 third year nursing students approaching their first clinical practicum. The new program included (a) simulated clinical encounters regarding situations of assessing hospitalized patents and caring for patients with oxygenation needs, (b) objective structured clinical examination of skills, (c) lectures, and (e) field trips. Data were analyzed using paired t-tests. RESULTS: After the ICN course, critical thinking skills(significant only between pretest and post-test2), communication competence, and clinical performance self-confidence improved significantly (p<.05). There was no improvement in the self-efficacy total score but there was significant improvement in the subscale, self-regulatory efficacy. CONCLUSIONS: The study results indicate that the ICN course may be effective in increasing critical thinking skills, communication competence, and clinical performance self-confidence in nursing students. However, the effect size was very small and modifications of this program should be considered to develop more cost-effective educational programs.

Crohn's disease is a condition of chronic inflammation involving potentially any location in alimentary tract, but it is worldwide the rare when primary lesion with its extent is confined to the appendix alone. Because clinical manifestations of the Crohn's disease of the appendix dose not differ from those of acute appendicitis, it is difficult to diagnose preoperatively or intraoperatively, so it is usually diagnosed by postoperative pathologic examination. Because Crohn's disease confined to the appendix has favorable prognosis than typical Crohn's disease, it is considered a separate disease entity from Crohn's disease, and a new diagnostic term-"idiopathic granulomatous appendicitis"-has gained wide acceptance in recent years. We experienced a case of Crohn's disease confined to the appendix or idiopathic granulomatous appendicitis and review, we reported the care with review of the literatures.
