In this paper, we propose a revised Deep Convolutional Neural Network (DCNN) model to extract Protein-Protein Interaction (PPIs) from the scientific literature. The proposed method has the merit of improving performance by applying various global features in addition to the simple lexical features used in conventional relation extraction approaches. In the experiments using AIMed, which is the most famous collection used for PPI extraction, the proposed model shows state-of-the art scores (78.0 F-score) revealing the best performance so far in this domain. Also, the paper shows that, without conducting feature engineering using complicated language processing, convolutional neural networks with embedding can achieve superior PPIE performance.

To study the lubrication performance of tilting-pad thrust bearing (TPTBs) during start-up in nuclear pump, a hydrodynamic lubrication model of TPTBs was established based on the computational fluid dynamics (CFD) method and the fluid-structure interaction (FSI) technique. Further, a mesh motion algorithm for the transient calculation of thrust bearings was developed based on the user defined function (UDF). The result demonstrated that minimum film thickness increases first and then decreases with the rotational speed under start-up condition. The influence of pad tilt on minimum film thickness is greater than that of collar movement at low speed, and the establishment of dynamic pressure mainly depends on pad tilt and minimum film thickness increases. As the increase of rotational speed, the influence of pad tilt was abated, where the influence of the moving of the collar dominated gradually, and minimum film thickness decreases. For TPTBs, the circumferential angle of the pad is always greater than the radial angle. When the rotational speed is constant, the change rate of radial angle is greater than that of circumferential angle with the increase of loading forces. This study can provide reference for improving bearing wear resistance.

The purpose of this study was to examine changes in students' awareness of online classes in university education over the three years from 2020 to 2022 during the COVID-19 pandemic. To achieve this, various aspects of online classes, including self-directed learning, interaction (between instructors and learners, and among learners), evaluation of the learning process and outcomes, and the learning environment and control of learning, were analyzed for changes from 2020 to 2022. The study included 534 university students enrolled in University A who participated in online classes in both 2020 and 2021. The results indicated that there was no significant difference in the awareness of self-directed learning, but significant differences were found in the awareness of interaction, evaluation of the learning process and outcomes, and the challenge related to learning environment and control of learning in online classes, which were higher in 2021 and 2022 than in 2020. Additionally, detailed changes in awareness of online classes showed significant differences in specific aspects of awareness in university online classes. In summary, students' awareness of online classes improved in 2021 and 2022 compared to 2020, as learners adapted to online classes due to the COVID-19 pandemic. Moreover, it was observed that difficulties in the challenge related to learning environment and control of learning were overcome in 2021. Based on these research findings, several implications for improving the design and operating strategies of effective online classes in future university education were proposed.

This study investigated the effect on children's literacy of teacher-child discussion about the contents of storybooks. The subjects were 10 experimental and 10 control 5-year-old kindergarten children in Cheongju. The experimental design was the Split Plot design. The research instruments used for pre- and post-tests were the Vocabulary Decoding Competence Test(Lee, 1998), Writing Competence Test(Lee & Lee, 1990), Story Comprehension Competence Test(Lee, 1998; Morrow, 1990), and the Emergent Reading Ability Judgements for Favorite Storybooks(Sulzby, 1985). Data were analyzed by ANOVA with repeated measures. Results showed that the teacher-child discussions about the contents of storybooks were effective for improving children's competence in decoding vocabulary, writing, and story comprehension but not for improving emergent reading ability.

In this paper, we propose a CT-SPI Model based on a physical computing for improving Computational Thinking(CT) for elementary students. This study analyzes the results obtained from applying the CT-SPI model to fourth-grade class. The model is designed to embrace the learning activities and CT elements for three different stages: System thinking, Prototyping and Interaction. For providing curriculum with CT-SPI model, physical SW educational module is developed, so that learners could focus on internalizing CT. The study results indicate that a learning satisfaction and a degree of learner interest improve significantly. Comprehensive CT capability assessment results in three levels show that the capability in lowest level (score is below 4 out of 10) has decreased by 46.6% but capability in highest level (over 7 out of 10) has increased by 20%.

The purpose of the study was to find out the level of knowledge, attitude, subjective norm, social interaction, and behavioral intention of nursing students regarding AIDS. It also identified factors that predict behavioral intentions and to provide care for patients with AIDS using Theory of Reasoned Action. The subjects consisted of 117 nursing students at three universities. Data was collected with self reporting in a questionnaire of with 67 items. Data was analyzed by an SPSS pc+ program. The results were as follows; 1. The mean age of the subjects was 20.98 years. The mean score for HIV/AIDS knowledge was 24.444 out of 32. Mostly Korean students were quite knowledgeable about the basic facts and symptoms of AIDS but confused about the made of transmission such as public toilets, prevention methods, and especially infection control. 2. This study found that social interaction, attitudes and subjective norms of Korean nursing students explained the intention to care for AIDS patients. The students who had a more positive attitude toward caring for AIDS patients and those who perceived more support from their significant others for caring the AIDS patients reported a more positive intention to care for AIDS patients. 3. In stepwise multiple regression analysis, 47.58% of the variance in AIDS patient care intention was accounted for by social interaction (33.41%), attitude (9.1%), and subjective norm (5.0 %). According to the finding of this study, and social interaction are the most significant predictors of intentions. Therefore it can be suggested that a HIV/AIDS prevention program should focus on transmission modes and prevention methods, especially in infection control. AIDS education efforts aimed at nursing students should place greater emphasis on correcting these kinds of misconceptions. Nursing intenvention for reducing fear of contagion, improving perception of social interaction, fostering positive attitudes and increasing intention to care for AIDS patients should be provided for nursing students. They also recommended that nursing students be adequately prepared to care for AIDS patients because of the increasing probability that they will encounter AIDS patients. Therefore it is important that education about HIV/AIDS should be incorporated within current undergraduate curriculum.
