The Educational Restitution Rate is an important parameter that determines the quality of university education. This paper analyzed data from 148 private universities over the 10 years from 2009 to 2018 using data mining techniques in Korea. A significant causal relationship is detected in the fixed effect model as a result of the panel estimation. And the scale of faculty expansion and fund management, which are the university evaluation indicators, and the size of basic funds, respectively, have a positive effect on the ERR, which is within the confidence interval. In the analysis, the more private universities improve the tuition dependence rate, the more decisively positive affecting ERR. As a result of nonparametric regression estimation, when the faculty expansion ratio is reinforced, the effect of economies of scale is detected in some sections, the improvement of the tuition dependence rate, and the result value is generated through the improvement that results are derived at a certain point in time. We hope that the university based on this study can be a basic Indicators for the diagnosis of basic competencies and policy of student-centered education.

This paper aims to study the seismic performance of external diaphragm connection between SST (square steel tube) column and H-shaped beam through experimental and analytical study involving finite element (FE) method and theoretical analysis. In the experimental study, three external diaphragm connection specimens with weak panel zone were tested under axial pressure on the top of the column and antisymmetric cyclic loads at the beam end to investigate the seismic performance of the panel zone. The hysteretic behavior, failure mode, stiffness and ductility of the specimens were discussed. Key point to be explored was the influence of the thickness of the steel tube flange on the shear capacity of the specimens. In the analytical study, three simplified FE models were developed to simulate the seismic behavior of the specimens for further analysis on the influence of steel tube flange. Finally, four existing calculation formulas for the shear capacity of the external diaphragm connection were evaluated through comparisons with the results of experiments and FE analysis, and application suggestions were put forward.

The study examined the effects of parenting process(supportive and involving mother-adolescent relationship, father-adolescent relationship) and school process(teachers' support, school life satisfaction) on adolescents' academic achievement and self-evaluation. Participants were 1787 middle school students (902 boys, 885 girls) in KEEP(Korean Education and Employment Panel). Structural equation modeling indicated that parenting and school process influenced adolescents' self-evaluation through adolescents' academic achievement. Also, the analysis with One Way ANOVA revealed that positive school (parenting) processes can serve a protective-stabilizing function when parenting(school) processes are negative.

An accurate and reliable performance evaluation technique is indispensable for the development of marine antifouling coatings. The existing standard practice is however, based on the visual observation of biofouling settlement area, which is prone to the subjective judgment of the inspector. In spite of the above mentioned importance, a systematic and objective fouling evaluation technique has not yet been introduced. In this study, a novel quantitative antifouling performance evaluation method for marine antifouling paints is devised based on the image analysis of panel immersion test results. The present image analysis method is to quantify settlement area for each fouling category by distinctive color. The fouling categories are set as unfouled, biofilm, green algae, brown algae, calcareous animal and spongy animal with specific HSL (Hue, Saturation, Lightness) color ranges. In order to assess the effectiveness of the proposed method, static immersion tests for three antifouling coatings were undertaken for two years.

Objective : Use of Internet for health related information is rapidly increasing. There is, however, no consensus as to which information is correct and reliable. This study was conducted to develop an evaluation standards for health related information on the Internet for the purpose of delivering correct information to internet users. Methods : A Delphi technique, which involved a panel of 65 experts, was used as the research design for this study. In the first round, the initial evaluation criteria which consisted of 12 items was developed through a literature review by the researcher and the items represented 2 categories, structure and function. In the second round, a semi-structured questionnaire was sent to the experts with the initial evaluation tool and the respondents identified 55 items. In the third round, these 55 items were analyzed for content validity by the experts and a total of 35 items were included in the model; 11 items in the structural area, 24 in the functional area. Conclusions : Development of indicators for the evaluation of internet site for health information is crucial to provide correct and reliable information. For evaluation to be effective further evaluation programs need to be developed so that users can be sure that the information they received is accurate.

With the development of information technology, more and more internet sites are available to consumers. Increasing on the interests of diet and health in modem society, there are numerous internet sites dealing with food, nutrition and health. Considering the importance and expected roles of internet sites in information dissemination in the future world, it is important to put more efforts to encourage internet sites with more accurate an useful information. Up to present, not much work has been done on quality analysis and evaluation of the internet information. This study aimed to develop a model to evaluate and rank the internet information according to its quality so that consumers can be guided toward correct information source. Three models were adapted from the literature for pilot study to develop a model suitable for evaluation of contents of sites related to food and nutrition information. From the pilot study, a evaluation model was developed with criteria more relevant to Korean internet site by expert panel. Evaluation criteria of the model is authority, accuracy, objectivity, coverage, and user-friendliness. For the objective and systematic evaluation, scores were assigned totaling maximum 100 point to each evaluation criteria factors. The model developed in this study could be used as one for other internet sites in area other than food and nutrition.

Purpose: Rapid detection of etiologic organisms is crucial for initiating appropriate therapy in patients with central nervous system (CNS) infection. This study aimed to evaluate the diagnostic value of the BioFire^® Meningitis/Encephalitis (ME) panel in detecting etiologic organisms in cerebrospinal fluid (CSF) samples from febrile infants. Methods: CSF samples from infants aged <90 days who were evaluated for fever were collected between January 2016 and July 2019 at the Seoul National University Children's Hospital. We performed BioFire^® ME panel testing of CSF samples that had been used for CSF analysis and conventional tests (bacterial culture, Xpert^® enterovirus assay, and herpes simplex virus-1 and -2 polymerase chain reaction) and stored at -70℃ until further use. Results: In total, 72 (24 pathogen-identified and 48 pathogen-unidentified) CSF samples were included. Using BioFire^® ME panel testing, 41 (85.4%) of the 48 pathogen-unidentified CSF samples yielded negative results and 22 (91.7%) of the 24 pathogen-identified CSF samples yielded the same results (enterovirus in 19, Streptococcus agalactiae in 2, and Streptococcus pneumoniae in 1) as those obtained using the conventional tests, thereby resulting in an overall agreement of 87.5% (63/72). Six of the 7 pathogen-unidentified samples were positive for human parechovirus (HPeV) via BioFire^® ME panel testing. Conclusions: Compared with the currently available etiologic tests for CNS infection, BioFire^® ME panel testing demonstrated a high agreement score for pathogen-identified samples and enabled HPeV detection in young infants. The clinical utility and cost-effectiveness of BioFire^® ME panel testing in children must be evaluated for its wider application.

This study analyzes the effects of the self-esteem on the life satisfaction of 2,040 middle school senior students using the Korean Children and Youth Panel Survey 2012 Data (KCYPS 2012) provided by the National Youth Policy Institute. In the ecological perspectives, this study considers two factors which influence the life satisfaction of the students; one factor is the environmental characteristics like parent intimacy, friend intimacy, teacher intimacy and study adaptation, and the other factor is the individual characteristics. In particular, self-esteem as one of the individual characteristics is divided into two separate categories, positive self and negative self. The two categories are found to have some interaction effects on the life satisfaction at the evaluation level. The effects of the negative self-evaluation on the life satisfaction appear to be different depending on the level of the positive self-evaluation. As the level of the positive self-evaluation becomes higher, the effects of the negative self-evaluation on the life satisfaction decreases. The life satisfaction becomes higher as the level of the negative self-evaluation is lower, and the life satisfaction is not high relatively at the low level of the positive self-evaluation. These results suggest that solving the adolescent's negative self-formation problem can not bring out the positive self-formation and there should be some plans for the positive self-formation more than simply solving the negative self- formation problem in order to improve the life satisfaction.
