This study reviewed the current status of low-experienced teacher librarians with less than 5 years and attempted to identify their educational needs through IPA analysis, Borich Priority Formula, and The Locus for Focus Model. A survey was conducted on low-experienced teacher librarians with less than 5 years of experience to analyze their process in the pre-service teacher training and experiences before an appointment and to identify teacher librarians instructional expertise. The results of the analysis of the study are as follows. First, there was a statistically significant difference between the importance and performance in all areas of instructional expertise of low-experienced teacher librarians. Second, 'reading education-practice progress' was recognized as a 'Keep up good work' with high importance and satisfaction, and 'library-based instruction planning, progress evaluation', 'information literacy-curriculum design', and 'digital and media literacy education-progress and evaluation' were recognized as areas of 'Concentrate here' through IPA analysis. Third, In the Borich Priority Formula, 'teaching-learning evaluation', 'teaching-learning progress', and 'teaching-learning plan' in the Library based instruction area showed the highest educational needs. Fourth, the library-based instruction was shown to the high discrepancy/high importancy area as same as the Borich Proity Formula. The results of this study can provide implications for improving the instructional expertise of teacher librarians.

In Machine learning, we usually divide the entire data into training data and test data, train the model using training data, and use test data to determine the accuracy and generalization performance of the model. In the case of models with low generalization performance, the prediction accuracy of newly data is significantly reduced, and the model is said to be overfit. This study is about a method of generating training data based on central limit theorem and combining it with existed training data to increase normality and using this data to train models and increase generalization performance. To this, data were generated using sample mean and standard deviation for each feature of the data by utilizing the characteristic of central limit theorem, and new training data was constructed by combining them with existed training data. To determine the degree of increase in normality, the Kolmogorov-Smirnov normality test was conducted, and it was confirmed that the new training data showed increased normality compared to the existed data. Generalization performance was measured through differences in prediction accuracy for training data and test data. As a result of measuring the degree of increase in generalization performance by applying this to K-Nearest Neighbors (KNN), Logistic Regression, and Linear Discriminant Analysis (LDA), it was confirmed that generalization performance was improved for KNN, a non-parametric technique, and LDA, which assumes normality between model building.

Child sexual abuse (CSA), under the age of 13, has increased over the past ten years, but research on the perceptions of perpetrators and victims have mainly focused on sexual violence against adults. Differentiating the age of the perpetrator into child, adolescent, and adult, the present study examined differences in perceptions of perpetrators and victims of child sexual abuse. The study also investigated differences by the gender of respondents, and examined the effects of Sexual Violence Myths (SVM) and Authoritarian Personality on perceptions of child sexual abuse. A total of 210 people in their 20s to 60s evaluated the degree to perpetrator blaming, perpetrator punishment, victim responsibility, and pain of the victim, and responded to the SVM scale and Authoritarian Personality scale. The correlation analysis, one-way ANOVA, independent samples t-test, and mediation analysis were conducted. The difference in the perception of perpetrator punishment by the age of the perpetrator was significant, indicating that respondents thought that adolescent perpetrators should be more severely punished than child perpetrators. Male respondents compared to female respondents were more likely to attribute the responsibility of sexual assault to the victim, to accept sexual violence myths and to be authoritarian. Sexual Violence Myths mediated the effects of the gender of respondents on the perception of victim responsibility, and Authoritarian Personality moderated these mediation effects. Finally, the limitations and implications of the study were discussed.

Disabled elderly faced with disability and the aged problems at the same time. So, this research creates two research questions and examines. First research question is how nine dimensions of daily life satisfaction according to gender difference. Second research question is how the factor of daily life satisfaction by gender difference. The data is sixty-five disabled elderly, 386 among Panel Survey of Employment for the Disabled(PSED, 2008). The methods of analysis for identifying research questions is t-test and multiple linear regression. The result of analysis on first research question, the gender difference six dimensions among nine dimensions of daily life satisfaction come out statistically significant. And The result of analysis on second research question, come out statistically significant, too. Socioeconomic status: the lower class, physical condition: bad health, chronic disease is or not, family and other people's social supports, disability: serious turn out to be factors in common. It has been suggested social policies from the results of studies that the provision of health support policy and program, enlarge assistance on daily life, support system on serious disabled elderly. On the other hand, analysis showed that distinctive factors between disabled elderly man and woman was age and education level. In other words, disabled elderly woman come out into the open that the more grow old, the less daily life satisfaction low, while disabled elderly man appeared higher daily life satisfaction in case of junior and senior high school graduate than uneducated.

Objective : This study was conducted to confirm the effect of the oral motor facilitation technique (OMFT) on oral motor function in stroke patients. Methods : This study was conducted on 72 stroke patients with dysphagia were included. Thirty-six patients were randomly assigned to the experimental and control groups were randomly classified into 36 patients each using a random table, and a two-group pre-post test was designed. The experimental group underwent OMFT, and the control group underwent traditional dysphagia therapy for 30 min, once a day, 5 times a week for 4 weeks, for a total of 20 sessions. The Comprehensive Orofacial Function Scale (COFFS) was used to evaluate oral motor function. Repeated-measures analysis of variance (ANOVA) was performed to confirm the effect of the period, and an independent t-test was performed to analyze the difference in change between the two groups. Results : Total COFFS scores improved in both groups. The experimental group showed significant changes in mandibular and lip movements, cheek blows, and tongue movements. In addition, there were significant differences depending on the intervention period in terms of masticatory distribution, food spillage, swallowing of solid and liquid foods, and voice changes. There were significant differences in the mandibular opening and closing categories between the two groups. Conclusion : OMFT is effective in improving oral motor function in stroke patients with dysphagia and can be used as basic evidence in clinical practice.

The purpose of this study was to analyze radiological technologists' (RT) task perceptions of intravenous injection behavior of contrast medium and use it as basic data for future workforce response plans. We surveyed a total of 172 RT using questionnaire terms consisting of demographic characteristics, job priorities, and RT' task perceptions of intravenous injection behavior. Statistical analysis was performed using descriptive statistics, frequency analysis, independent samples T-test, and ANOVA analysis. As a result, first, current clinical RT were highly aware of the need for intravenous injection behavior as a response to the future workforce of them, and the workload burden resulting from this was evaluated as low. Second, the fear of intravenous injection behavior was found to be significant, so it is judged to be useful to perform them as selective job actions rather than all RT' task. Third, the need for training courses and certification for RT' intravenous injection behavior is being raised, and additional specific research on this is required. Last, RT' positive perception of intravenous injection behavior could be expected as a foundation for improving national medical services, strengthening RT expertise, and expanding tasks.

The purpose of this study was to estimate the optimal stand density criteria for each growth stage of Chamaecyparis obtusa (Siebold & Zucc.) Endl. to achieve the timber production goal for cypress forests and develop an optimal silvicultural system for forest thinning. A relative yield index (Ry) value of 0.75, presented as a stand density management criterion index, was estimated by analyzing the relationship characteristics between the composition ratio and stand density of slender trees from 216 sample plots of the recruited cypress forests. The analysis of the feasibility of achieving each production target in the existing silvicultural system for C. obtusa revealed that the growth rate according to the parameters of forest land productivity, such as site index and thinning intensity according to the increase in age, was not properly reflected. In the thinning system for each timber production target analyzed in this study, 353 high-quality large hardwoods from 498.1 m³/ha, 703 high-quality medium hardwoods from 376.2 m³/ha, and 1,758 small-diameter hardwoods from 249.5 m³/ha could be harvested. Although the silvicultural system prepared on the basis of the results of this study cannot be uniformly applied according to various management goals, this study is meaningful in that it presents empirical reference standards based on the stand density management diagram that reflects the growth characteristics of cypress forests in South Korea.
