As the number of Coronavirus Disease-19 (COVID-19) patients increases in a global pandemic situation, the usefulness of mobile computed tomography (CT) is gaining attention. Currently, mobile CT follows the basic safety and essential performance evaluation criteria of whole-body or limited-view X-ray CT in order to obtain device approval and evaluation in the Republic of Korea. Unlike stationary CT, mobile CT is not operated in shielded areas but rather areas such as intensive care units, operating rooms, or isolation rooms. Therefore, it requires a different basic safety and essential performance evaluation standard than stationary CT. In this study, four derived basic safety evaluation criteria related to electrical, mechanical, and radiation safety were included (dose indication test, protection against stray radiation, safety measures against excessive X-rays, half-value layer measurement); and seven essential performance evaluation criteria were included (tube voltage accuracy, mAs accuracy, radiation dose reproducibility, CT number of water, noise, uniformity, and spatial resolution); total eleven basic safety and essential performance evaluation criteria were selected. This study aims to establish appropriate basic safety and essential performance evaluation criteria for simultaneously obtaining images with diagnostic value and reducing the exposure of nearby patients, medical staff, and radiologic technologists during the use of mobile CT.

Human papillomavirus (HPV) is a causative agent for a subset of oropharyngeal cancer (OPC). The current standard of care (SOC) for locally advanced OPC is 70 Gy definitive radiotherapy (RT) concurrent with cisplatin, which entails significant proportions of acute and late grade 3 or higher toxicities. Accordingly, discovery of favorable prognosis of HPV-related OPC has led to enthusiasm to attenuate subspecialties therapy in multidisciplinary treatment. Diverse deintensification strategies were investigated in multiple phase 2 trials with an assumption that attenuated treatments result in comparable oncologic outcome and less toxicities compared with SOC. Several trials on chemotherapy deintensification revealed that concomitant administration of cisplatin is not to be omitted or substituted for cetuximab without compromising progression-free survival or local control. A transoral robotic surgery (TORS) is investigated as alternative local treatment, but TORS plus SOC or mild deintensified adjuvant RT showed similar toxicities and inferior oncologic outcomes compared with SOC definitive RT or moderately deintensified RT. However, it has been reported that TORS plus deintensified 30-36 Gy adjuvant RT results in excellent outcome and less late toxicity compared with SOC adjuvant RT. Several phase 2 trials reported apparently equivalent progression-free survival and local control and similar adverse effects with moderately deintensified 60 Gy RT compared with SOC 70 Gy RT. Further dose reduction below 60 Gy has been investigated using biology-directed approaches, which use response to induction chemotherapy or metabolic images to triage HPV-positive OPC for deintensified RT. In summary, these trials provide valuable insights for future directions. Available evidence consistently showed that moderately deintensified RT is effective and safe for HPV-positive OPC in both definitive and adjuvant settings. Concurrent cisplatin remains an essential component without which progression-free survival is significantly compromised for advanced HPV-positive OPC. A simple incorporation of TORS to SOC may be detrimental for oncologic outcome without anticipated toxicity reduction. Given the lack of level 1 evidence, it is prudent to curb an unjustified deviation from the current SOC and limit any deintensified strategies to clinical trials and adhere to the current SOC.

Breast cancer is the most dangerous and deadly form of cancer. Initial detection of breast cancer can significantly improve treatment effectiveness. The second most common cancer among Indian women in rural areas. Early detection of symptoms and signs is the most important technique to effectively treat breast cancer, as it enhances the odds of receiving an earlier, more specialist care. As a result, it has the possible to significantly improve survival odds by delaying or entirely eliminating cancer. Mammography is a high-resolution radiography technique that is an important factor in avoiding and diagnosing cancer at an early stage. Automatic segmentation of the breast part using Mammography pictures can help reduce the area available for cancer search while also saving time and effort compared to manual segmentation. Autoencoder-like convolutional and deconvolutional neural networks (CN-DCNN) were utilised in previous studies to automatically segment the breast area in Mammography pictures. We present Automatic SegmenAN, a unique end-to-end adversarial neural network for the job of medical image segmentation, in this paper. Because image segmentation necessitates extensive, pixel-level labelling, a standard GAN's discriminator's single scalar real/fake output may be inefficient in providing steady and appropriate gradient feedback to the networks. Instead of utilising a fully convolutional neural network as the segmentor, we suggested a new adversarial critic network with a multi-scale L1 loss function to force the critic and segmentor to learn both global and local attributes that collect long- and short-range spatial relations among pixels. We demonstrate that an Automatic SegmenAN perspective is more up to date and reliable for segmentation tasks than the state-of-the-art U-net segmentation technique.

This study aims to analyze the recognition and demands of church school kindergarten teachers enrolled in a kindergarten teacher training program. 278 kindergarten teachers in the Seoul and Gyeonggido area were chosen as the research objects and questionnaires were distributed to and recollected from them. The questions cover 3 areas: the recognition, necessity and contents of the training program for kindergarten teachers. The data from the collected questioners were processed to bring in frequency and percentage by question and an X2 test was employed to see whether there was a difference among background variables. In addition, mean and standard deviation were used for the questions regarding the program contents. The results showed that the teachers had a deep interest in and awareness of the necessity of the program. Among the demographic variables, they turned out statistically different by academic career, education-related career and major. Second, the list of the demands they made for the training contents for kindergarten teachers showed that they wanted, in the order of importance; educating parents, understanding young children, handling techniques of troubled children, effective communication skills with young children, and understanding their traits and teaching methods by trait and spiritual training of teachers.

In many countries the demographics clearly informs us that an aging population represent a serious problem. To this extent senior citizens welfare does matter it has developed into a public debate and genuine concern. it seems that the social issues are focused on how the socity views the social welfare policies. In a modern welfare state where the emphasis lies in pursing a high standard of living and thereby high quality of life. This does not cover the very well the old people in society, but the government clearly carries an obligation to look after and care for the retired & old people in the society. This obligation the social and economic impact that an old person faces as he/she grows old. it is important ensure that their lives carries a meaning and that they as a group will not be estranged from the mainstream of society just because they are considered to be part of the aging population. The key issues that must be addressed are 1) The impact of reduced spending power from less income. a lower income stream; 2) increasing health problems and costs; 3) the natural degradation of ones physical & mental powers; 4) and thereby an isolation from the public in general. So clearly the social policy related to the old people in society should be developed with the consent of what they believe is important to them. To ensure their minimum income level that a beneficiary of an old person's pension will receive, the monthly pension should be reflected by the official price index and be adjusted accordingly. by making the job market open for the senior citizens, expending the mandatory retirement age, give companiesincentives to hire senior citizens, there maybe an opportunity to extend to the aging population the possibility to continue to participate in the society at large.

Background: Epithelial ovarian cancer (EOC) is the commonest malignancy involving the ovaries. Maximum surgical cytoreduction (MCR) followed by adjuvant taxane-platinum chemotherapy are the standard of care treatments. Aims: To study treatment outcomes of EOC patients that were maximally cyto-reduced and received adjuvant paclitaxel-carboplatin (PC) chemotherapy. Materials and Methods: This retrospective cohort study included 174 patients with EOC treated at the Egyptian National Cancer Institute between 2006 and 2010. For inclusion, they should have had undergone MCR with no-gross residual followed by adjuvant PC chemotherapy. MCR was total abdominal hysterectomy/bilateral salpingo-oophorectomy [TAH/BSO] or unilateral salpingo-oophorectomy [USO] plus comprehensive staging. Results: The median age was 50 years. Most patients were married (97.1%), had offspring (92.5%), were postmenopausal (53.4%), presented with abdominal/pelvic pain and swelling (93.7%), had tumors involving both ovaries (45.4%) without extra-ovarian extension i.e. stage I (55.2%) of serous histology (79.9%) and grade II (87.4%). TAH/BSO was performed in 97.7% of cases. A total of 1,014 PC chemotherapy cycles were administered and were generally tolerable with 93.7% completing 6 cycles. Alopecia and numbness were the commonest adverse events. The median follow up period was 42 months. The 2-year rates for disease free survival (DFS) and overall survival (OS) were 70.7% and 94.8%, respectively. The respective 5-year rates were 52.6% and 81.3%. Advanced stage and high-grade were significantly associated with poor DFS and OS (p<0.001). Age >65 years was associated with poor OS (p =0.008). Using Cox-regression, stage was independent predictor of poor DFS and OS. Age was an independent predictor of poor OS.

Objective: To report a fatal case of Multidrug-resistant Acinetobacter baumannii (MDR-AB) in a patient with interstitial lung disease (ILD) on high-dose glucocorticoids. Case Summary: A 66-year-old man with a history of coniosis was transferred to the hospital with progressive cough and sputum production. This patient has been diagnosed with pneumonia and ILD on admission, requires antimicrobial therapy and systemic immunosuppressants. He received high dose of methylprednisolone and cyclophosphamide for ILD as well as ceftriaxone and azithromycin for pneumonia. On day 7 in the intensive care units (ICUs), patient had fever and leukocytosis, thus antimicrobials were switched to piperacillin. After 13 days in the ICU, Acinetobacter baumannii and methicillin-resistant Staphylococcus aureus (MRSA) were isolated on transtracheal aspirate (TTA) and meropenem was initiated. However, it was revealed a multidrug-resistant Acinetobacter baumannii (MDR-AB) species, resistant to carbapenem. Patient was administered colistin but expired due to septic shock on day 84. Discussion: Systemic immunosuppressive therapy can result in infections that may compromise patient's survival. MDR-AB has emerged as a serious cause of nosocomial infections in immunocompromised patients. MDR-AB is resistant to most standard antimicrobials and therapeutic options are limited. Conclusion: We report our recent experience with a fatal MDR-AB pneumonia in a patient with ILD, who had to be treated with high dose glucocorticoids and immunosuppressnts.

Purpose: The purpose of this study was to identify the relationship between fatigue, and self-efficacy in patients with lung cancer. Method: The data was collected from January 21th to April 8th 2001. The study subjects were recruited from K hospital in Pusan, Korea. Their fatigue was measured using the 22-item Revised Piper Fatigue Scale developed by Piper et al. (1998) and translated by the investigators, and self-efficacy was measured using the 10-item General Self-efficacy Questionnaire developed by Lee, Schwarzer & Jerusalem. The data were analyzed by SPSS 10.0 program using frequency, percentage, mean and standard deviation, t-test, ANOVA, Post-hoc test (Scheffe's test), and Pearson Correlation Coefficients. Result: 1) The mean fatigue score was $118.48{\pm}33.02$ (range: 22-220). The scores for sub-dimension were $35.40{\pm}10.06$ in behavior/severity, $25.98{\pm}9.06$ in affective score, $27.88{\pm}10.06$ in sensory score, and $29.22{\pm}8.27$ in cognitive/mood. The mean self-efficacy score was $28.80{\pm}5.85$. 2). There were significant differences in the fatigue of patients with lung cancer on income per month (F=4.651, p= .014), 'present pain' (F=2.601, p= .012), 'change of weight' (F=5.911, p= .005), by general characteristics. 3) There were significant differences in the self-efficacy of patients with lung cancer on 'religion' (F=3.732, p= .031), 'employment status' (F=5.525, p= .003), 'past therapy' (F=2.869, p= .034), by general characteristics 4) There was a significant negative correlation between fatigue and self-efficacy (r=- .528, p= .000). Conclusion: Patients with lung cancer experience fatigue. Increased fatigue is associated with decreased self-efficacy. Nurses must provide patients with nursing care for the less occurrence of fatigue and interventions to manage self-efficacy for them.

This study aimed at figuring out the current state of 26 family-health support centers in Gyeonggi-do, in order to prepare an activation plan for the centers. These centers are the main mediators of the family health operation. This study also aimed to understand the center users' satisfaction and demands. The results were as follows. First, a total of 65,794 participants from 9,960 businesses were processed. The majority had attended various integrated family services, followed by family counseling and/or family-friendly culture-establishing businesses. Second, the main users' profiles were as follows: average age, 41; average number of persons in the family, 3.78; education above foundation-level degree; diverse jobs that included special occupations; average monthly incomes of 3,390,000 won; and a middle-class living standard (as self-described by participants). Third, the users' main concern for their families was "financial difficulties," and they had an interest in education and counseling. Although they thought education and counseling were suitable solutions, they hesitated because they did not think their problems were serious enough to merit them. Fourth, the satisfaction level of their participation in their center's program was generally high, at 3.9-4.2 points. The majority of them said they would attend again in the future.
