  • This paper describes the construction of knowledge data retrieval management system based on medical image CT. The developed system is aimed to improve the efficiency of the hospital by reading the medical images using the intelligent retrieval technology and diagnosing the patient 's disease name. In this study, the medical image DICOM file of PACS is read, the image is processed, and feature values are extracted and stored in the database. We have implemented a system that retrieves similarity by comparing new CT images required for medical treatment with the feature values of other CTs stored in the database. After converting 100 CT dicom provided for academic research into JPEG files, Code Book Library was constructed using SIFT, CS-LBP and K-Mean Clustering algorithms. Through the database optimization, the similarity of the new CT image to the existing data is searched and the result is confirmed, so that it can be utilized for the diagnosis and diagnosis of the patient.

  • Background: Research in the field of informational needs of breast cancer patients is scarce. In the few published articles, these needs were usually not satisfied. The main objective of this study was to evaluate satisfaction regarding informational needs in women with breast cancer. The long-term goal was to guide physician-patient communication to meet these needs. Materials and Methods: A survey with 21 questions was completed by 84 female patients receiving chemotherapy in a one-day hospital in Beirut, Lebanon. All patients were aware of their disease and agreed to participate in the survey. Results: The doctor was the major source of information for patients followed by media (radio and television). The level of knowledge of patients concerning their disease was proportional to the number of information sources. Women aged younger than 45 years, diagnosed during the last three months before the survey and certified from high school were less satisfied with information given by the oncologist. The missing information was in relation with the steps of the treatment after the chemotherapy regimen, the risk of a family member (sisters and daughters) of developing the disease and management of lymphedema. Conclusions: This study generated a scale for the degree of satisfaction of information received by women with breast cancer from their oncologist. The physician can use this scale to improve his or her skills of communication to patients and diminish their level of fear and anxiety.

  • Purpose: Postoperative nausea and vomiting (PONV) is very common among postoperative orthopedic surgical patients with patient-controlled analgesia (PCA), especially for narcotics. Therefore, the purpose of this study was to investigate the effects of an evidence-based PONV management protocol on nursing and patient outcomes. Methods: A methodological study was conducted to develop PONV protocol and a quasi-experimental study to evaluate the effectiveness of protocol. The preliminary PONV protocol was drawn by conducting a systematic review and by reviewing clinical guidelines and best practice recommendations. Validation of the content was done by expert clinicians, and the clinical applicability was evaluated by staff nurses and patients. The effect was evaluated in clinical outcomes associated with PONV and nursing outcomes. Results: In the experimental group, the occurrence of vomiting (z= 2.147) was significantly decreased, the maintenance PCA (${\chi}^2=4.212$) and the satisfaction of patients (z= 5.007) were significantly higher. In the outcomes of nurses, the PONV knowledge of nursing care (z = 3.791), awareness (z = 2.982) and self-efficacy (z= 2.745) were higher in the experimental group. The attitude towards evidence-based nursing practice (z= 2.446) was significantly positive. Conclusion: The results show that an evidence-based approach to the implementation of PONV care is effective in improving patient clinical outcomes and quality of care.

  • The cyclic alternating pattern (CAP) is a periodic EEG activity in NREM sleep, characterized by sequences of transient electrocortical events that are distinct from background EEG activities. A CAP cycle consists of two periodic EEG features, phase A and subsequent phase B whose durations are 2-60 s. At least two consecutive CAP cycles are required to define a CAP sequence. The CAP phase A is a phasic EEG event, such as delta bursts, vertex sharp transients, K-complex sequences, polyphasic bursts, K-alpha, intermittent alpha, and arousals. Phase B is repetitive periods of background EEG activity. The absence of CAP more than 60 seconds or an isolated phase A is classified as non-CAP. Phase A activities can be classified into three subtypes (A1, A2, and A3), based on the amounts of high-voltage slow waves (EEG synchrony) and low-amplitude fast rhythms (EEG desynchrony). CAP rate, the percentage of CAP durations in NREM sleep is considered to be a physiologic marker of the NREM sleep instability. In insomnia, the frequent discrepancy between self-reports and polysomnographic findings could be attributed to subtle abnormalities in the sleep tracing, which are overlooked by the conventional scoring methods. The conventional scoring scheme has superiority in analysis of macrostructure of sleep but shows limited power in finding arousals and transient EEG events that are major component of microstructure of sleep. But, it has recently been found that a significant correlation exists between CAP rate and the subjective estimates of the sleep quality in insomniacs and sleep-improving treatments often reduce the amount of CAP. Thus, the extension of conventional sleep measures with the new CAP variables, which appear to be the more sensitive to sleep disturbance, may improve our knowledge on the diagnosis and management of insomnia.

  • Background: Hypertension is a major cause of cardiovascular disease and associated mortality, and postmenopausal women are at a high risk of hypertension. We aim to investigate the hypotensive effect and safety of acupuncture, focusing on postmenopausal women with prehypertension and stage 1 hypertension. In addition, we aim to investigate whether the effect of acupuncture treatment differed, depending on Sasang Constitution and cold-heat pattern. Methods: This study is designed as an intervention cohort study. Two hundred postmenopausal women aged <65 years with prehypertension or stage 1 hypertension living in Daejeon city in Korea will be recruited, and randomly assigned to either an acupuncture or no-treatment control group. The intervention will consist of four sessions; one session will include acupuncture performed 10 times for 4 weeks. There will be a 20-week observation period after each session, and the total study duration will be 96 weeks. Acupuncture will be applied at the bilateral Fengchi (GB20), Quchi (LI11), Zusanli (ST36), and Sameumgyo (SP6) acupoints. The effect of acupuncture will be evaluated by comparing the change in systolic and diastolic blood pressure between the acupuncture and control groups every 4 weeks until the end of the study. Discussion: To evaluate the success of blood pressure management, long-term observation is required, but no long-term studies have been conducted to evaluate the effect of acupuncture on blood pressure in postmenopausal women. To our knowledge, this study will be the first long-term study to investigate this issue for more than 6-8 weeks.

  • Purpose: The purpose of this study was to develop nurses' core competencies and sub-competencies and to verify the validity and importance-performance of core competencies. Methods: The core competencies of nurses were derived through an analysis of strengths, weaknesses, opportunities, and threats, as well as a literature analysis of domestic and foreign accreditation institutions. Validity and importance-performance analyses were conducted on the core competencies derived from nursing colleges nationwide. Results: Six core competencies of nurses were revealed: integration of knowledge and nursing skills, critical thinking, communication, leadership, safety management, and global competency. Further, eighteen sub-competencies were derived. The content validity ratio values for the core competencies were higher than 0.74. Communication skills among multidisciplinary teams and communication skills among nursing teams were shown to be the most important competencies to be improved. Conclusion: The results of this study are meaningful in terms of how the core competencies of nurses were derived and evaluated for the fourth cycle of nursing education accreditation according to the changes of time and culture.

  • Objectives: To compare the effectiveness and safety of East Asian traditional medicine treatments (EATMT) versus conventional management in patients following heart valve replacement surgery. Methods: We searched several databases, including the Korean Studies Information Service System, PubMed, China National Knowledge Infrastructure, and Citation Information by NII. The search range included randomized controlled trials from each first issue until June 27, 2021. Two review authors independently extracted the data. We assessed the risk of systematic errors by evaluating risk domains using the "Risk of bias" tool. Results: We included 5 trials in the review. In the EATMT, the investigators reported significant improvements in reshaping of the heart structure: left ventricular end diastolic diameter (MD -4.43, 95% CI -6.06 to -2.79; 130 participants; 2 studies; high evidence). Comparisons with usual care revealed a significant decrease in gastrointestinal complications rate (OR 0.30, 95% CI 0.20 to 0.47; 503 participants; 2 studies; high evidence). We assessed 4 studies as having a low risk of bias and 1 study as having a high risk of bias. Conclusion: This systematic review suggests that East Asian traditional medicine interventions may be effective in preventing and alleviating complications, but we found evidence of important trade-offs between known benefits and known adverse effects in cardiac dysfunction and inflammation following heart valve replacement. Consequently, additional high-quality studies should be conducted.

  • Background & objectives: Understanding the awareness of policy targets and implementers about safety in the local community is the crucial to establish a systematic community safety policy. The purpose of this study was to identify the perception of local citizens and civil servants regarding community safety and its related factors. Methods: For achieving this research goal, this study conducted survey targeting 538 citizens and 404 civil servants in S-si, Kyunggi-do. Self-administred and web-based survey were used to collect data from April 1st to 16th 2021. Results: Civil servants scored higher in community safety perception than citizens, and S city's safety interest, information, and participation scores were also higher than those of citizens. Based on the results of multiple regression, thought about in interest of safety in S-si, providing and sharing about safety information to citizens, and participation of community safety policy were significantly associated with perception of community safety. Conclusions: Setting safety as the top priority in S city policy and paying attention to safety by the mayor, public officials, and city council members is an important way to raise citizens' awareness of local safety. Also, efforts at the city level are needed to foster safety knowledge through systematic education on safety.

  • Purpose : Lymphedema is a common complication in mastectomy patients and is usually characterized by pain, swelling, and limited range of motion (ROM) in the arm. Electromyostimulation (EMS) is widely used for the rehabilitation and recovery of subjects with various neuromusculoskeletal disorders after breast cancer. However, EMS has not yet been used in many Pilates exercises. This study was aimed at comparing the effects of instrument Pilates integrated with EMS on pain, lymphedema, and ROM of the upper extremity (UE) in breast cancer subjects after mastectomy. Methods : Nine female breast cancer subjects who had undergone mastectomy participated in the study. The subjects underwent instrument Pilates with EMS (experimental group) or instrument Pilates only (control group). Pain, lymphedema, and ROM of the UE were measured using the visual analog scale (VAS), the circumference length of the UE, and the ROM of the UE. The Wilcoxon signed-rank test was used to compare the pain, lymphedema, and ROM of the arm before and after the intervention, and the Mann-Whitney U test was used to compare the two groups. The statistical significance level was set to p < .05. Results : In the experimental group, there were significant differences in pain (p<.05) and UE circumference (p<.05) before and after intervention. However, there was no significant difference between the two groups in VAS (p>.05) or circumference length of the UE (p>.05). There was one significant difference between the groups in terms of internal rotation of the ROM of the UE (p<.05). Conclusion : These results show that instrument Pilates exercises combined with EMS may positively affect the internal rotation of the ROM of the UE in breast cancer patients after mastectomy, thus contributing to existing knowledge about instrument Pilates using EMS for the effective management of in breast cancer subjects after mastectomy.
