Background: Healing of the tendon itself is not always related to successful clinical outcomes after rotator cuff repair. It was hypothesized that certain radiologic factors affecting clinical outcomes could exist in case of the retear after arthroscopic rotator cuff repair (ARCR) and the radiologic factors could help predict clinical process. The purpose of this study was to identify the radiologic factors associated with clinical outcomes of the retear after ARCR. Methods: Between January 2012 and December 2019, among patients with sufficient footprint coverage for ARCR, 96 patients with Sugaya classification 4 or higher retear on follow-up magnetic resonance imaging were included. The association between clinical outcomes such as American Shoulder and Elbow Surgeons (ASES) score, Constant score and range of motion and radiologic variables such as initial tear dimension, retear dimension, variance of tear dimension, critical shoulder angle, acromial index, and acromiohumeral distance was analyzed. Results: Preoperatively, the ASES and Constant scores were 59.81±17.02 and 64.30±15.27, respectively. And at the last follow-up, they improved to 81.56±16.29 and 78.62±14.16, respectively (p<0.01 and p<0.01). In multiple linear regression analysis, the variance of the mediolateral dimension of tear had statistically significant association with the ASES and Constant scores (p<0.01 and p=0.01). Conclusions: In patients with the retear after ARCR, the variance in the mediolateral dimension of tear had significantly negative association with the clinical outcomes. This could be considered to be reference as relative criteria and needed more sample and mechanical study.

Objectives: Eight Constitution Medicine (ECM) categorizes individuals into eight constitutions based on physiological differences in organ relations and recommends different diets for different constitutions. This study presents a preliminary analysis of the effect of following constitutional food regimens on quality of life and health outcomes for different constitutions. Methods: This cross-sectional, comparative study used subjects recruited from Essen University Hospital Traditional Chinese Medicine Center in Germany. From a convenience sample of 243 Germans, those in the groups Hepatonia/Cholecystonia (n = 95) and Pulmotonia/Colonotonia (n = 26) were analyzed for health outcomes in relation to their dietary habits of either including or avoiding meat. Health outcomes were measured with SF-36, self-reported survey. Results: The two groups had no significant differences in the health outcomes of SF-36. However, subjects in Hepatonia/Cholecystonia who had followed their dietary habit for more than 20 years had significantly better scores on general health, social functioning, mental health, emotional role functioning, and mental component scores than those in Pulmotonia/Colonotonia, regardless of their meat intake. Conclusions: This study established initial groundwork for considering patients' constitutions when evaluating health outcomes and their relation to diet. Further studies are warranted on the effects of regulating food intake according to individual constitution.

The variety of learners include students with disabilities and general students, and an ongoing focus of inclusive education research is non-discrimination. As part of integrated education, UDL (Universal Design for Learning) for students with disabilities supports a practical approach, participation, and advancement to improve learning opportunities for all students. The purpose of this study was to examine the effects of using UDL in science classes. The dependent variables of this study were academic achievement in science, scientific attitude, and scientific motivation. In this study, the experimental groups were 9 people in the 5th grade and 11 people in 6th grade. The experimental groups were taught science class using UDL. In order to analyze the learning outcomes, the structure equation model was performed. The results of this study were as follows: First, the science achievement of learning outcomes of the science class applying UDL directly affected both scientific attitude and scientific motivation. Second, the scientific attitude of learning outcomes of the science class applying UDL directly did not affect scientific motivation. According to these results, learning outcomes for science achievement of the science class applying UDL showed that UDL affected both general students and students with disabilities. To summarize the analysis of learning outcomes, science achievement directly affected both scientific attitude and scientific motivation while scientific attitude did not affect scientific motivation. This study offered a specific implementation method for integrated education. Using the structure equation model for analyzing the effect has more significance.

Background: Red blood cell (RBC) transfusion improves cardiorespiratory status of preterm infants by increasing circulating hemoglobin, improving tissue oxygenation, and reducing cardiac output. However, RBC transfusion itself has also been suggested to negatively affect short-term outcomes such as intraventricular hemorrhage (IVH), bronchopulmonary dysplasia (BPD), retinopathy of prematurity (ROP), and necrotizing enterocolitis (NEC) in premature infants. Purpose: This study aimed to analyze the relationship between RBC transfusion and short-term outcomes in very low birth weight (VLBW) infants (birth weight, <1,500 g). Methods: We retrospectively reviewed the medical records of VLBW infants admitted to the Soonchunhyang University Bucheon Hospital between October 2010 and December 2017. Infants who died during hospitalization were excluded. The infants were divided into 2 groups according to RBC transfusion status. We investigated the relationship between RBC transfusion and short-term outcomes including BPD, ROP, NEC, and IVH. Results: Of the 250 enrolled VLBW infants, 109 (43.6%) underwent transfusion. Univariate analysis revealed that all short-term outcomes except early-onset sepsis and patent ductus arteriosus were associated with RBC transfusion. In multivariate analysis adjusted for gestational age, birth weight and Apgar score at 1 minute, RBC transfusion was significantly correlated with BPD (odds ratio [OR], 5.42; P<0.001) and NEC (OR, 3.40; P= 0.009). Conclusion: RBC transfusion is significantly associated with adverse clinical outcomes such as NEC and BPD in VLBW infants. Careful consideration of the patient's clinical condition and appropriate guidelines is required before administration of RBC transfusions.

This study was executed to be used as the basic data for the improvement of Korean Chinese undergraduates' English proficiency. Descriptive statistics and t-tests were used for data analysis on the differences between Korean Chinese and Han Chinese students' preparedness and learning outcomes of 203 undergraduates at a four-year college in China. Results showed that Korean Chinese students were significantly less prepared and had weaker learning outcomes than Han Chinese students. Analysis on the factors that affected learning outcomes showed significant differences in oral English skills, attitudes toward curriculum, beliefs in their own fluency, and learning strategies. On the other hand, no group difference was shown in learning interests. Based on these findings, implications for the improvement of Korean Chinese undergraduates' preparedness and learning outcomes in EFL class were described.

Background: Information asymmetry between physicians and patients is one of the most unique characteristics of health care. But as consumerism spreads in health care sector, health care consumers are searching comparative information about quality and cost of providers from many information sources. Providing comparative information to health care consumers not only makes consumers choose hospital rationally, but also invigorates the health care market by providers' competition. However there are few studies regarding information searching behavior of health care consumers, then this study is carried out. Methods: The purpose of this study is to understand the information searching behavior of health care consumers based on their characteristics and the types of medical institutions. For this purpose, 313 spinal patients' data of 11 medical institutions (university hospital, spine specialized hospital, clinic) located in Seoul were collected by self-administered surveys. Results: The results of this study are as follows: 1) t-test/analysis of variance analysis showed that according to various characteristics of health care consumers and the types of medical institutions, the level of information searching of each source and the amount of information searching and searching outcomes are statistically different. 2) Regression analysis showed that influence on searching outcomes are statistically different according to the level of information searching of each source and searching content and the amount of information searching has positive effects on searching outcomes. Conclusion: The significance of this study is to provide empirical basis for establishment of health care policy reflecting information needs and preference of health care consumers.

This paper re-examines the impacts an institutional arrangement may have on labour market outcomes such as the employment and unemployment rates. Based on the results from a generalized econometric model, the generosity of unemployment insurance benefits, organized labour and active labour market policy have effects on a labour market in line with previous findings. However, taxes on labour and the degree of employment protection are found to affect neither the employment rate nor the unemployment rate. Thus, some findings in this paper validate earlier findings, whereas others do not.

Background/Aims: Nonagenarians will purportedly account for 10% of the United States population by 2050. However, no studies have assessed the outcomes of nonvariceal upper gastrointestinal bleeding (NVUGIB) in this age group. Methods: The National Inpatient Sample database between 2016 and 2020 was used to compare the clinical outcomes of NVUGIB in nonagenarians and octogenarians and evaluate predictors of mortality and the use of esophagogastroduodenoscopy (EGD). Results: Nonagenarians had higher in-hospital mortality than that of octogenarians (4% vs. 3%, p<0.001). EGD utilization (30% vs. 48%, p<0.001) and blood transfusion (27% vs. 40%, p<0.001) was significantly lower in nonagenarians. Multivariate logistic regression analysis revealed that nonagenarians with NVUGIB had higher odds of mortality (odds ratio [OR], 1.5; 95% confidence interval [CI], 1.3-1.7) and lower odds of EGD utilization (OR, 0.86; 95% CI, 0.83-0.89) than those of octogenarians. Conclusions: Nonagenarians admitted with NVUGIB have a higher mortality risk than that of octogenarians. EGD is used significantly in managing NVUGIB among nonagenarians; however, its utilization is comparatively lower than in octogenarians. More studies are needed to assess predictors of poor outcomes and the indications of EGD in this growing population.
