Purpose: The purpose of this study was to develop a standardized education protocol for peritoneal dialysis patients. Methods: First, the demand for education was investigated from the 27 patients on peritoneal dialysis and 16 guardians, and later, the standardized nursing education protocol has been developed through the comprehensive literature review and the critical analysis of the related studies. Contents validity and applicability have been tested through the expert group survey. Results: The standardized peritoneal dialysis nursing education protocol with 9 areas and 20 items has been developed. The content validity for timing and duration, contents, method, and place of education proposed by the protocol were all above than 0.8. In terms of the applicability of the protocol, the experts scored between 4.20 to 4.93 for all items except one. The item on home visit education acquired the lowest applicability score, because there might exist potential restrictions in visiting patient's home. Conclusion: The standardized education protocol developed in this study turned out to be adequate by representing high content validity for all items and the applicability also was high except the item on home visit education. Further researches to test the effects of this education protocol should be done.

The rapid diffusion of information and telecommunication (IT) technologies during the recent decennia produced fundamental changes in the economic activity at a global level, resulting in what became coined as the "new economy". However, empirical evidence on the contribution of IT equipment to growth and productivity is at best mixed, with the more or less consistent results on the positive link between the two relating to the United States in the 1990-s. Although the empirical literature on the link between IT investment and economic performance employs a wide variety of methodologies, the overwhelming majority of the studies appears to be employing the assumption of linearity of the IT-performance relationship and predominantly explores the direct nature thereof. In this study we relax both these assumptions and find that the indirect, or aggregate productive efficiency, effects of IT investment are as important as are the direct ones The estimated non-linear nature of the indirect relationship between IT investment intensity and productive efficiency accommodates the concepts of critical mass and complementary (infrastructure) capital offered in the literature. Our key finding is that the world economy′s average level of IT investment intensity remained below the estimated critical mass. Since in this study we developed a methodology that allows one to explicitly measure the critical mass of IT investment intensity, its individual estimation at a country or industrialsector level may help evaluate the extent to which IT investment activity has to be encouraged or discouraged.

Purpose : This study aimed to understand and describe the nurses' experiences caring for severe COVID-19 patients at isolation room with negative pressure in South Korea. Methods : Data were collected through individual in-depth interviews from February 16 to March 31, 2021 with 11 nurses who had been caring for severe COVID-19 patients at isolation room. Verbatim transcripts were analyzed according to Colaizzi's phenomenological analysis. Results : As a result, 5 theme clusters were extracted about nurses' experiences. The 5 theme clusters, "Adapting to unexpected adversity", "Accepting unresonable and heavy work", "Dulness and disconnection from the outside world", "Changing in perception of new infectious diseases", and "Pathetic isolated patients" emerged. Conclusion : The results of this study provided a deeper understanding of nurses struggling to care for COVID-19 severe patients. This study is expected to be useful in providing basic evidence for improving intensive care practices and for preparing policies in other infection disease situations.

The effect of $BaCeO_3$ doping on the critical current density of YBCO film by TFA-MOD method was studied. $BaCeO_3$ doping was made by two method; one is direct addition of $BaCeO_3$ nano-sized powder prepared by citrate process followed by grinding with planetary ball mill for 10 hours. Another is addition of Ba-Ce precursor solution prepared with Ba-acetate and Ce acetate dissolved in TFA to the YBCO-TFA precursor solution. The film was made by standard dip coating and heat treatment process with conversion temperature of $790^{\circ}C$ in 1000 ppm oxygen containing moisturized Ar gas atmosphere. The direct addition of $BaCeO_3$ powder resulted in YBCO film with good epitaxial growth and no evidence of second phase formation. The addition through precursor solution resulted in the increase of critical current density upto 30 at% doping and uniform dispersion of $BaCeO_3$ fine inclusion was confirmed by SEM-EDX.

Purpose : Developing infection control capabilities during the COVID-19 pandemic was critical. This study aimed to develop a simulation program to control patients with COVID-19 in nursing students and examine the effects on COVID-19 knowledge, COVID-19 nursing intention, self-efficacy learning, and clinical performance. Methods : The study used nonequivalent control group pretest-posttest design. Sixty nursing students were recruited from two different colleges using purposive sampling. For the intervention group(n=30), the pretest was administered before the simulation program, involving six sessions of online lectures and simulation practices. Immediately, the posttest was conducted following the program. Results : COVID-19 knowledge (t=9.87, p <.001), COVID-19 nursing intention (t=4.45, p <.001), learning self-efficacy (t=6.49, p <.001), and clinical performance (t=6.77, p <.001) increased significantly after the program, revealing the positive effect of the COVID-19 infection control simulation program in nursing students. Conclusion : The results of the study and the curriculum may be used as practical evidence for COVID-19 infection control in nursing schools and medical institutions.

A 55-year-old woman was admitted for an elevated serum carbohydrate antigen-125 (CA-125) level, and a left pleural effusion, which were detected at a routine health examination. Computed tomography of the chest was performed upon admission, revealing extensive bilateral paratracheal and mediastinal lymph node enlargement with a massive left-sided pleural effusion. Subsequent analysis of the pleural fluid demonstrated consistency with an exudate, no evidence of malignant cells, and a normal adenosine deaminase. However, the pleural fluid and serum CA-125 levels were 2,846.8 U/mL and 229.5 U/mL, respectively. A positron emission tomography did not reveal any primary focus of malignancy. Finally, a surgical mediastinoscopic biopsy of several mediastinal lymph nodes was performed, revealing non-necrotizing granulomas, consistent with sarcoidosis. After a month of treatment of prednisolone, the left pleural effusion had resolved, and after 2 months the serum CA-125 level was normalized.

Purpose: This study aimed to develop an evidence-based extracorporeal membrane oxygenation (ECMO) nursing protocol for critically ill patients receiving ECMO treatment by using an adaptation process, and to verify the effects of the protocol. Methods: The protocol was developed according to the adaptation guidelines. A non-randomized controlled trial was conducted to test the protocol's effects. Data were collected between April 2019 and March 2021. The differences in physiological indicators and complication rates between the two groups were investigated using a chart review to evaluate patient outcomes. The nurses' outcome variables were evaluated using a questionnaire. Results: First, after reviewing 11 guidelines by appraisal of the guidelines for research and evaluation collaboration II, 5 guidelines with a standardization grade of over 50 points were selected. An ECMO nursing protocol was developed based on these guidelines. Second, there were no statistically significant differences in physiological indicators between the two groups of patients. However, the experimental group showed a statistically significant decrease in the infection rate (p = .026) and pressure injury rates (p = .041). The levels of satisfaction with ECMO nursing care, and empowerment and performance of the nurses who used the ECMO nursing protocol were higher than those of nurses who did not (p < .001). Conclusion: This protocol may help prevent infections and pressure injuries in patients, and improve nurses' satisfaction and empowerment. The nursing protocol developed for critically ill patients receiving ECMO treatment can be utilized in evidence-based nursing practice.

Bilateral interstitial infiltration in chest radiography, which may be fine granular, reticular or of ground glass opacity, is the typical radiographic findings of Pneumocystis jiroveci pneumonia. Recently, atypical radiographic features, including cystic lung disease, spontaneous pneumothorax or nodular opacity, have been reported intermittently in patients with P. jiroveci pneumonia. We report the case of a 29-year-old woman with a transplanted kidney whose simple chest radiography and HRCT scan showed numerous miliary nodules in both lungs, mimicking miliary tuberculosis (TB). Under the presumptive diagnosis of miliary TB, empirical anti-TB medication was started. However, Grocott methenamine silver nitrate staining of a transbronchial lung biopsy tissue revealed P. jiroveci infection without evidence of TB. These findings suggest that even in TB-endemic area other etiology such as P. jiroveci as well as M. tuberculosis should be considered as an etiology of miliary lung nodules in mmunocompromised patients.
