Purpose: This study was done to identify the effectiveness of the 'intervention - mother's recorded song' on low-birth weight infants in an neonatal intensive care unit (NICU). Methods: This study was conducted with a nonequivalent control group pre-posttest quasi-experimental design and the participant group was low-birth weight infants who were admitted to the NICU. Forty-eight infants, 24 in each from two groups, the experimental and control group, participated in the study. Results: For physical response according to vital signs, there were no significant statistical differences in heart rate, respiration rate and pulse oximetry saturation between the experimental group and the control group. For behavioral state, there was a significant statistical difference between the experimental and control group. Conclusion: The study results indicate that the intervention using mother's song had some significance as a nursing intervention with positive impacts. Such an intervention can help pediatric nurses improve infants' stabilization of their vital signs and behavioral states. By showing the effectiveness of such an intervention, the results of this study provide further evidence-based information in developing the practice of pediatric nursing.

Objectives The purpose of this study was to investigate the effectiveness of the Gongjin-dan (Gongchen-dan, here in after GJD) in order to obtain the evidence for clinical application. Methods The GJD-related articles published from 1990 to 2013 were searched using "Korean Traditional Knowledge Portal", "Oriental Medicine Advanced Searching Integrated System (OASIS)", "Korean Association of Medical Journal Edition (Koreamed)", "Research Information Services (RISS4U)", "Korean Medicine Database (KMbase)", "National Discovery for Science Leader (NDSL)", "PubMed", "China National Knowledge Infrastructure (CNKI)". The search keywords were "Gongjin-dan", "Gongchen-dan". Thirty-nine articles were obtained. After excluding the eighteen article which did not meet inclusion criteria, finally twenty-one articles were included; five clinical articles and sixteen experimental articles. Results In clinical studies, GJD has the various effectiveness in cardiovascular diseases, alcoholic hepatitis, mild dementia, anemia. Also experimental studies related to the GJD show a variety of effects, such as anti-oxidative activity, neuroprotective activity, hepatoprotective activity, anti-inflammatory activity, immunological activity, reproductive recovery activity with fewer side-effects. Conclusions It has been suggested that there are various effects of GJD in treating a wide-range disease. However, in order to put GJD to use for many kinds of diseases in more reasonable ways, it is needed to publish well-design clinical trial based on the variety of results of experimental studies.

The primary goal of this study was to compute sample sizes required to achieve the each aim of a variety of foot-and-mouth disease (FMD) surveillance programs, using a statistically valid technique that takes the following factors into account: sensitivity (Se) and specificity (Sp) of diagnostic test system, desired minimum detectable prevalence, precision, population size, and desired power of the survey. In addition, sample sizes to detect FMD if the disease is present and also as proof of freedom were computed. The current FMD active surveillance programs consist of clinical, virological, and serological surveillance. For the 2012 serological surveillance, annual sample sizes (n = 265,065) are planned at four separate levels: statistical (n = 60,884) and targeted (n = 115,232) at breeding pig farms and slaughter house, in together with the detection of structural proteins (SP) antibodies against FMD (n = 88,949). Overall, the sample size was not designed taking the specific aims of each surveillance stream into account. The sample sizes for statistical surveillance, assuming stratified two-stage sampling technique, was based to detect at least one FMD-infected case in the general population. The resulting sample size can be used to obtain evidence of freedom from FMD infection, not for detecting animals that have antibodies against FMD virus non-structural proteins (NSP). Additionally, sample sizes for targeted surveillance were not aimed for the population at risk, and also without consideration of statistical point of view. To at least the author's knowledge, sampling plan for targeted, breeding pig farms and slaughter house is not necessary and need to be included in the part of statistical surveillance. Assuming design prevalence of 10% in an infinite population, a total of 29 animals are required to detect at least one positive with probability of 95%, using perfect diagnostic test system (Se = Sp = 100%). A total of 57,211 animals needed to be sampled to give 95% confidence of estimating SP prevalence of 80% at the individual animal-level with a precision of ${\pm}5%$, assuming 800 herds with an average 200 heads per farm, within-farm variance of 0.2, between-farm variance of 0.05, cost ratio of 100:1 of farm against animals. Furthermore, 779,736 animals were required to demonstrate FMD freedom, and the sample size can further be reduced depending on the parameters assumed.

The purpose of this study is to study the service physical environment, customer satisfaction and returning intention of beauty shop. Structured questionnaires and interviews were conducted to investigate these correlations and analyzed by IPA method. The physical environment in the beauty shop was analyzed as an important factor in creating an environment that can stimulate the emotional part of the customers. It is found that the atmosphere, the emotional atmosphere and the installation of the auxiliary facilities are important factors in the physical environment. Customer satisfaction was found to increase satisfaction with employees' intention, such as satisfaction with employees. The customer 's revisit intention shows that they are trying to communicate and share their experiences through customer satisfaction. It was found that it is important to meet customers' emotional needs through improving the physical environment of the stores and to improve the emotional satisfaction of customers based on this. Strategic implications for attracting customers in the beauty shop suggest that increasing satisfaction with existing customers is an important strategy in securing not only existing customers but also prospective customers.

The purpose of this study was to examine the characteristics of domestic research into breast-feeding intervention education geared toward mothers and the content of the intervention based on the existing literature in an effort to provide information on how to offer the best intervention. Domestic studies reported between January 1993 and December 2014 were analyzed using four different databases. Fifteen studies were selected from 76 studies included in the databases after performing the searches. How long breast-feeding intervention remains effective should be studied to secure scientific rationales, which is one of the proper nursing interventions to boost breast feeding. As a result of analyzing the papers according to Whittmore and Knaf's integrative review method, the individual educational intervention was offered in two papers, and the individual education and group education were both provided in four. In nine papers, individual education, group education, phone counseling and education by home visits were all offered. Follow-up studies should be conducted by adopting a systematic research design to find more scientific evidence for appropriate nursing interventions to boost breast-feeding. These results will be useful for the development of educational programs for breast-feeding if more accurate information on breast-feeding education for mothers can be obtained.

This study was conducted to review and analyze the academic-related satisfaction intervention programs for Korean nursing students and to provide evidence-based data. The data included in the meta-analysis were 25 studies published from 2001 to July 2018, and the design of the study consisted of 1 randomized controlled trial and 24 non-randomized controlled trials. The study subjects were nursing students from 1st to 4th grade, and the intervention program was conducted in theoretical and practical classes. The sample size was 1182 (mean: 47.3) in the experimental group and 1137 in the control group (mean: 45.5). The intervention program consisted of 1~16 weeks/1~16 sessions/7~240 minutes per session. Dependent variables were as follows: major satisfaction, learning satisfaction, satisfaction with the classroom practice, and satisfaction with the clinical practice. Satisfaction with the classroom practice (Hedges' g=0.876[95% CI: 0.405, 1.346]), satisfaction with the clinical practice (Hedges' g=0.515[95% CI: 0.312, 0.718]), and overall academic-related satisfaction (Hedges' g=0.630[95% CI: 0.371, 0.889]) were statistically significant and above intermediate levels in the meta-analysis. The study results are significant in that the objective results were confirmed by integrating the previous studies dealing with the academic-related satisfaction intervention program of nursing students.

Objective: The aim of present study was to evaluate the effectiveness of low-dose intravenous immunoglobulin (IVIg) therapy in women with recurrent spontaneous abortions (RSA) and elevated pre-conceptional peripheral blood CD56+Natural Killer (NK) cell percentage. Study Design: Retrospective case control study. Materials and Methods: Thirty three women with RSA and elevated pre-conceptional peripheral blood CD56+NK cell percentage who had received low-dose IVIg therapy (400 mg/kg per day, every 4 week, until 20 gestational weeks) were included in this study. Controls were nine women with RSA and elevated pre-conceptional peripheral blood CD56+ Natural Killer (NK) cell percentage who had not received IVIg therapy were included in this study. Medical records of study and control groups were retrospectively analyzed and we compared the successful pregnancy outcomes between two groups. Successful pregnancy outcome was defined as pregnancy ongoing beyond 25 gestational weeks. Results: Age, number of previous abortions, pre-conceptional CD56+NK cell percentage and type of RSA were not statistically different between two groups. Otherwise, twenty-five women who received IVIg therapy (25/33, 75.8%) but, only three women who had not received (3/9, 33.3%) had a successful pregnancy outcome and the rate difference between two groups was statistically significant. Conclusion: Based on our study, low-dose IVIg therapy have a effective role in treatment of RSA patients with elevated pre-conceptional peripheral blood CD56+ Natural Killer (NK) cell percentage, but more larger scaled prospective study is needed for available of conclusive evidence.

Health care workers (HCWs) are more than ten times more likely to be infected with coronavirus infectious disease 2019 (COVID-19) than the general population, thus demonstrating the burden of COVID-19 among HCWs. Factors that expose HCWs to a differentially high-risk of COVID-19 acquisition are important to elucidate, enable appropriate public health interventions to mitigate against high risk and reduce adverse outcomes from the infection. We conducted a systematic review and meta-analysis to summarize and critically analyze the existing evidence on SARS-CoV-2 risk factors among HCWs. With no geographical limitation, we included studies, in any country, that reported (i) the PCR laboratory diagnosis of COVID-19 as an independent variable (ii) one or more COVID-19 risk factors among HCWs with risk estimates (relative risk, odds ratio, or hazard ratio) (iii) original, quantitative study design, and published in English or Mandarian. Our initial search resulted in 470 articles overall, however, only 10 studies met the inclusion criteria for this review. Out of the 10 studies included in the review, inadequate/lack of protective personal equipment, performing tracheal intubation, and gender were the most common risk factors of COVID-19. Based on the random effects adjusted pooled relative risk, HCWs who reported the use of protective personal equipment were 29% (95% CI: 16% to 41%) less likely to test positive for COVID-19. The study also revealed that HCWs who performed tracheal intubations were 34% (95% CI: 14% to 57%) more likely to test positive for COVID-19. Interestingly, this study showed that female HCWs are at 11% higher risk (RR 1.11 95% CI 1.01-1.21) of COVID-19 than their male counterparts. This article presents initial findings from a living systematic review and meta-analysis, therefore, did not yield many studies; however, it revealed a significant insight into better understanding COVID-19 risk factors among HCWs; insights important for devising preventive strategies that protect them from this infection.

Due to the popularization of smartphones, most of the recorded speech files submitted as evidence of recent crimes are produced by smartphones, and the integrity (forgery) of the submitted speech files based on smartphones is emerging as a major issue in the investigation and trial process. Samsung smartphones with the highest domestic market share are distributed with built-in speech recording applications that can record calls and voice, and can edit recorded speech. Unlike editing through third-party speech (audio) applications, editing by their own builtin speech applications has a high similarity to the original file in metadata structures and attributes, so more precise analysis techniques need to prove integrity. In this study, we constructed a speech file metadata database for speech files (original files) recorded by 34 Samsung smartphones and edited speech files edited by their built-in speech recording applications. We analyzed by comparing the metadata structures and attributes of the original files to their edited ones. As a result, we found significant metadata differences between the original speech files and the edited ones.

Gwanghwadang-Wonsam was designated as National Folklore Cultural Heritage No. 52 in 1979, it is in good condition. However, a problem is the attached a phoenix insignia badge that did not exist when it was designated recently. As it became known as the only purple Wonsam artifact with "phoenix insignia", raising the need for its conservation. In this regard, scientific analysis was required to correct misinformation about designated cultural assets and restore the original designated state by analyzing the history of the Gwanghwadang-Wonsam, other relics of the phoenix insignia and its making design patterns. An X-ray fluorescence analysis was used to confirm that the Phoenix insignia's metal threads were titanium-plated silver. Phoenix insignia using titanium-plated gold thread was not identified in Gwanghwadang-Wonsam photographs in 1986, and the TiN-type membrane plating method was used in various industries in the 1990s, which can be estimated to be attached in the early and mid-1990s. Especially, the scientific analysis results from the X-ray fluorescence analysis in this study provide key evidence for conservation processing. This study demonstrates the importance of investigating relics and similar artifacts in the conservation process of inherited relics and as a precedent for restoration that corrects misinformation about designated cultural properties.
