The purpose of this study was to identify changes and differences in perceptions of disabilities, attitudes toward inclusive education, and teacher efficacy in Early childhood pre-service teachers through capstone design-based disability teaching material production classes. The study participants were 50 third-year child care majoring students (25 experimental group, 25 comparison group) who participated in capstone design class for one semester in 2020 at 3-year K university. Looking at the results of the study, the experimental group, which produced teaching materials for the disabilities, showed significant changes in disability awareness, attitude toward inclusive education, and teacher efficacy than the comparative group. there was a positive change in the perception of disability due to an increase in the overall understanding and knowledge of the disabilities. It is judged that these positive changes in the perception of people with disabilities gave positive changes to the attitude toward inclusive education and teachers' efficacy. This positive change of early childhood pre-service teachers will serve as an opportunity to improve the quality of teaching behavior and various roles of teachers when interacting with children with disabilities in the inclusive education field.

Small area variations in health care utilization have long been studied as an important issue related to boto cost containment and quality assurance. This study was conducted to investigate if variations in hospital services across small geographic areas in Korea existed. The claims data of the fiscal year 1992 obtained from the regional health insurance societies were used for the study. Main findings of the research can be summarized as follows : 1. Extremal Quotients(EQ) of hospital expenditure per capita and hospital days per capita varied among diagnosis types. The EQ ranged from 2.05(cataract) to 41.67(pneumonia) in hospital expenditure per capita and from 1.86(cataract) to 45.89(pneumonia) in hospital days per capita. The diagnosis groups which showed high variation were pneumonia, cephalo-pelvic disproportion, gastritis and duodenitis, fracture of rib, and acute bronchitis. Those which showed low variation were acute appendicitis and cataract. 2. The EQ level of admission rate was different in terms of diagnosis types, ranging from 2.57(catarct) to 44.45(pneumonia). The variations were high in medical disorders such as pneumonia, oephalo-pelvic disproportion, gastritis and duodenitis and acute bronchitis, while relatively low in surgical conditions such as acute appendicitis and cataract. 3. As an indicator of service intensity, the EQ of expenditure per admission ranged from 1.67(acute appendicitis) to 31.27(essential hypertension). The diagnoses which had high variation were essential hypertension, gastric ulcer, whereas those which had low variation were cephalopelvic disproportion and acute appendicitis. With regard to hospital days per admission, the EQ ranged from 1.55(acute appendicitis) to 28.13(gastric ulcer) by diagnosis types. The diagnosis groups with showed high variation were gastric ulcer, essential hypertension, and acute bronchitis, whereas those with low variation were cephalo-pelvic disproportion, intervertebral disc disorders, and acute appendicitis. Both the expenditure and hospital days per admission showed lewwer variations than the expenditure per capita, hospital days per capita and admission rate. 4. Comparing patterns of variation in utilization indices, diagnoses such as essential hypertension, gastric ulcer, fracture of rib showed higher variations in expenditure per admission than in admission rates, whereas diagnoses such as pneumonia, cephalo-pelvic disproportion and gastric ulcer showed higher variations in admission rate than expenditure per admission. These findings suggest that wide variations existed in several diagnoses groups across small areas in Korea. Further research should be performed to investigate factors related to small area variations including provider behavior.

Prediction of corporate failure using past financial data is a well-documented topic. Early studies of bankruptcy prediction used statistical techniques such as multiple discriminant analysis, logit and probit. Recently, however, numerous studies have demonstrated that artificial intelligence such as neural networks can be an alternative methodology for classification problems to which traditional statistical methods have long been applied. In building neural network model, the selection of independent and dependent variables should be approached with great care and should be treated as model construction process. Irrespective of the efficiency of a teaming procedure in terms of convergence, generalization and stability, the ultimate performance of the estimator will depend on the relevance of the selected input variables and the quality of the data used. Approaches developed in statistical methods such as correlation analysis and stepwise selection method are often very useful. These methods, however, may not be the optimal ones for the development of neural network model. In this paper, we propose a genetic algorithms approach to find an optimal or near optimal input variables fur neural network modeling. The proposed approach is demonstrated by applications to bankruptcy prediction modeling. Our experimental results show that this approach increases overall classification accuracy rate significantly.

This study examined the accessibility of emergency rooms according to the population density and distance in Daegu Metropolitan City to help improve the quality and emergency medical accessibility problems in Daegu Metropolitan City. To observe the geographical requirements, the number of population in eup, myeon, dong, available emergency, and available emergency compared to the population were mapped through the S-GIS of Statistics Korea to visualize the data based on the 3km radius. To determine the difference in accessibility to emergency rooms for each district in Daegu Metropolitan City, the data were analyzed by ANOVA and Scheffe. According to the average number of emergencies available in Daegu Metropolitan City within a 3-kilometer radius were 5.7 in Jung-gu, 5.0 in Nam-gu, 1.6 in Buk-gu, 0.4 in Dong-gu, 2.4 in Seo-gu, 0.9 in Suseong-gu, 3.5 in Dalseo-gu, and 0.1 in Dalseong-gun; there was a statistically significant difference (p<.001). The available emergency within a 3km radius and available emergency per 1,000 people were concentrated in the center. Therefore, it may be necessary to institute an urban emergency medical network by establishing a point that serves as an intermediate hub to provide emergency medical care to citizens far from the center.

The purpose of this study was to examine and compare the perceptions of mothers about the Nuri curriculum for 5-year olds. The subjects were 382 mothers whose 3-5-year old children went to kindergartens (192 mothers) and daycare centers (190 mothers). The findings were as follows: First, the majority of the mothers knew that the Nuri curriculum for 5-year olds started to be carried out in 2012, but many of them weren't told about the details at all. Second, the mothers considered the Nuri curriculum necessary, and were roughly satisfied with the ongoing Nuri curriculum for 5-year olds. Third, there was no difference in the mothers' perceptions of environmental factors required for the Nuri curriculum. Fourth, the mothers whose children went to kindergartens chose warm and enthusiastic character as important quality of teachers. The mothers whose children went to daycare centers chose friendly and caring character as important qualities of teachers. Fifth, the mothers perceived that the Nuri curriculum was relatively useful for the qualitative improvement of early childhood education and childcare. Sixth, the majority of the mothers didn't have their children transfer to another early childhood education institution after the Nuri curriculum for 5-year olds was carried out.

Environmental DNA (eDNA) is a genetic material derived from organisms in various environments (water, soil, and air). eDNA has many advantages, such as high sensitivity, short investigation time, investigation safety, and accurate species identification. For this reason, it is used in various fields, such as biological monitoring and searching for harmful and endangered organisms. To collect eDNA from a freshwater ecosystem, it is necessary to consider the target organism and gene and a wide variety of items, such as on-site filtration and eDNA preservation methods. In particular, the method of collecting eDNA from the environment is directly related to the eDNA concentration, and when collecting eDNA using an appropriate collection method, accurate (good quality) analysis results can be obtained. In addition, in preserving and extracting eDNA collected from the freshwater ecosystem, when an accurate method is used, the concentration of eDNA distributed in the field can be accurately analyzed. Therefore, for researchers at the initial stage of eDNA research, the eDNA technology poses a difficult barrier to overcome. Thus, basic knowledge of eDNA surveys is necessary. In this study, we introduced sampling of eDNA and transport of sampled eDNA in aquatic ecosystems and extraction methods for eDNA in the laboratory. In addition, we introduced simpler and more efficient eDNA collection tools. On this basis, we hope that the eDNA technique could be more widely used to study aquatic ecosystems and help researchers who are starting to use the eDNA technique.

The purpose of this study is to have college students who took 'University Character Education Using YouTube Videos', which was opened as a liberal arts course in college, directly produce UCC assignments with the theme of personality. Despite the recent paradigm shift in learner-centered education, teacher-centered education still hinders learners' motivation to participate in classes. To solve this problem, a learner-led UCC production process is necessary for the practice of effective learner-centered education. For this purpose, a phenomenological research method was applied. The research participants were 10 students, in-depth interview was used for data collection, and Colaizzi's research method was selected for data analysis. As a result of the analysis, 9 themes, 4 theme clusters, and 2 categories were derived. The results are as follows. First, they recognized that the UCC assignments were a field of maturity, such as practicing the right thoughts and actions, and re-establishing the concept of character. Second, they said that the UCC production process was an opportunity to increase their self-esteem. Third, they showed a more mature personality by recognizing that the UCC assignments became a chance to pay attention to others beyond themselves. Fourth, they had the greatest difficulty in selecting a topic while carrying out the UCC project, and they were experiencing the limitations of high-quality projects due to the technical immaturity of UCC production. Finally, this study was concluded by discussing the educational implications based on the results. These results provide a suggestion that more effective character education can be expected when tasks led by learners will be developed and an interactive arena where students can be shared are provided.

Current wireless sensor networks are considered to support more complex operations ranging from military to health care which require energy-efficient and timely transmission of large amounts of data. In this paper, we propose an adaptive temporal suppression algorithm which exploits a temporal correlation among sensor readings. The proposed scheme can significantly reduce the number of transmitted sensor readings by sensor node, and consequently decrease the energy consumption and delay. Instead of transmitting all sensor readings from sensor node to sink node, the proposed scheme is to selectively transmit some elements of sensor readings using the adaptive temporal suppression, and the sink node is able to reconstruct the original data without deteriorating data quality by linear interpolation. In our proposed scheme, sensing data stream at sensor node is divided into many small sensing windows and the transmission ratio in each window is decided by the window complexity. It is defined as the number of a fluctuation point which has greater absolute gradient than threshold value. We have been able to achieve up about 90% communication reduction while maintaining a minimal distortion ratio 6.5% in 3 samples among 4 ones.

Domestic casino companies strongly demand their employees to provide high quality customer services for improving customer's satisfaction and to minimize customer's complain to achieve organizational objective. This seriously influences the job stress, job satisfaction and turnover of employees. However, ongoing management is necessary for job satisfaction and turnover intention of employees because which are related to organizational effectiveness and factors able to maximize the profit. In this study, we examined the influence and causal relationship of job stress from emotional labor of employees on job satisfaction and turnover intention of employees. As a result, job stress had a full mediating effect in the relationship between emotional labor, job satisfaction and turnover intention. It was confirmed that emotional labor of casino employees could cause job stress and further influence job satisfaction and turnover intention. In order to reduce job stress and improve job satisfaction, we propose the improvement of overall human management structure and company environment of casino companies. Emotional education such as emotional regulation ability, empathy, and interpersonal skills should be strengthened to reduce job stress from emotional labor, and the self-esteem program will be helpful to casino employees to maintain the emotional positiveness and maximize their working abilities.
