This study is to discover the diverse issues related to Self-Directed Learning Screening (SDLS) and draw implications by analyzing its critical points. Using content analysis and interviews with admission officers, tentative issues were finalized and reviewed by researchers and educators. A Survey was developed based on the 96 issues after having evidence of content validity using the Delphi method. To conduct survey, e-mails were sent to admissions officers in twenty science specialized high schools. They were asked to response to questions about perceptions of critical issues and if there are any issues in their schools. Using mean scores of two factors based on its critical issues and frequencies, a two-dimensional classification table for each type was presented. Four critical issues for each type were discovered. The first type indicates minor issues that include 28 items that were less than the overall mean scores in terms of critical issues and its frequencies. The second type indicates tentative issues that include 29 items that were greater than the mean score in critical issues but less in its frequencies. The third type indicates general issues that include 17 items that were less than the mean score in critical issues but greater in its frequencies. The last type indicates critical issues that include 22 items that were greater than the mean scores in two factors. The discovered results of critical issues and its types in this study can be considered a core part of the screening process in schools, especially, critical issues should play an important role in the process of admission screening planning.

The purpose of the present study is to compare paper and pencil test utilized to identify gifted students so far to the recently introduced teacher observation-recommendation system. More specifically, this study compared intelligence, career patterns, and self- regulated learning abilities of gifted students who were identified through those two different identification system to explore the possibility of the newly introduced teacher observation-recommendation system. The results show that there was no significant difference in the aspect of overall IQ score. However, students who were identified through the observation-recommendation system showed significantly higher scores at some subscores of intelligence test, such as vocabulary application, comprehension, and schematization. In the aspects of career patterns, about 72% of gifted students who were identified through the previous paper and pencil test belonged to the 'investigative' category of Holland. But more diverse career patterns such as enterprising, social, realistic, conventional including investigative categories were found in those students who were identified by the observation-recommendation system. There were also significant differences in the self-regulated learning abilities between two groups of students. Practical implications of the study were discussed in depth.

The purpose of this study was to identify the effect of Career Education Program(CEP) on freshmen of nursing department. A non-equivalent pre-post test of quasi-experimental design was used. 44 freshmen were assigned to an intervention group and 36 freshmen to a control group. The intervention program was composed of introduction, self-navigation, explore the world of work, career design and termination during 12 weeks from March to June, 2014. Data were collected before-and after program, and analyzed using the SPSS 22.0 program. There were significant increases in learning motivation (t=8.92, p<.001) and college life adaptation (t=3.51, p<.001) in the experimental group compared to the control group. This study suggests that CEP would be an efficient way to adapt to school and take learning motivation for nursing students. It is necessary to develop a systematic and tailored career education program for nursing students from a freshmen to a senior.

This study investigates convergent influence on Self Factors(SF), Stress Factors(STF), Resilience & Control Factors(RCF), Test Anxiety(TA), Learning Flow(LF) and academic burnout among Health College Students in TOEIC class(HCST). The survey was administered to 291 HCST from 1 college located in J area during the period from April 3, 2017 to April 14, 2017. The structured self-administered questionaries were used. With the analysis of covariance structure, we could confirm relationship among the six factors such as SF, STF, RCF, TA, LF and academic burnout. The results of the study indicate that the efforts, to manage these factors, are required to decrease the academic burnout of HCST. Squared multiple correlations, which explain the academic burnout related with the stress from economic pressure and job seeking, test anxiety, learning flow and self factors, were 98.8%. The results are expected to be useful for the development of TOEIC learning curriculum and course to decrease the academic burnout of HCST. In the following study, the analysis about additional factors of influence on academic burnout will be needed.

In this study, the relationships among students' cognitive/affective variables, cognitive conflict induced by anomalous data, and conceptual change were investigated. Tests regarding background knowledge, field dependence-independence, learning strategy, logical thinking ability, goal orientation, self-efficacy on prior concept and ability, and control belief were administered. Tests of prior conceptions, responses to anomalous data, conception, and retention of conception were also administered. There were no significant correlations of cognitive conflict induced by anomalous data with students' cognitive and affective variables. However, prior knowledge on molecular motion, field dependence-independence, and learning strategy were significantly correlated with students' conception and retention of conception. Logical thinking ability was also correlated with their conception. Multiple regression analysis indicated that learning strategy significantly predicted students' conception and retention of conception. For the affective variables, self-efficacy on ability was significantly correlated with students' conception and retention of conception, and goal orientation was correlated with their conception. Self-efficacy on ability was a significant predictor on students' conception and retention of conception, and goal orientation on their conception.

Lee Ik(李瀷) had put emphasis on the achievements by self-regulated academic learning through doubts, and at the same time that it was all-embracing. His academic attitude had set an example among the members of Seongho school(星湖學派), and his disciples had strived to emulate his style. The greatness of Seongho(星湖)'s study had been revealed by development of Seongho school(星湖學派) right after his death. He had argued that the six strokes of I-Ching should be read having it divided into inward and outward divine signs. He had stated his view clearly that the divine signs ranging from one stroke to six strokes were not connected, same as Shao yong(邵雍)'s method, but, the three strokes of inward divine sign as well as the three strokes of outward divine signs were independent from each other. Seongho(星湖) also had raised many questions about Shifa(筮法), and Bianyao(變爻) and Zhuzi(朱子)'s Shifa(筮法), or Yixueqimeng("易學啓蒙") "Kaobianzhan("考變占")". In view of the Shifa(筮法), Seongho(星湖) had helped Dasan(茶山) to present 'Shiguafa(蓍卦法)' by proposing different divination rule from Zhuzi(朱子)'s Method of Divination by Shiyi("筮儀"). Seongho(星湖) had not professed something significantly different from Zhuzi(朱子) in his I-xue. His study on I-xue had been accomplished under his goal of achievements by self-regulated academic learning through doubts. "Shiguakao("蓍卦攷")" is also same. I-xue of Seongho(星湖) had made a great contribution to form Dasan(茶山)'s I-xue in the later years.

In hashing-based image retrieval, the hash code of a manipulated image is different from the original image, making it difficult to search for the same image. This paper proposes and evaluates a self-supervised deephashing model that generates perceptual hash codes from feature information such as texture, shape, and color of images. The comparison models are autoencoder-based variational inference models, but the encoder is designed with a fully connected layer, convolutional neural network, and transformer modules. The proposed model is a variational inference model that includes a SimAM module of extracting geometric patterns and positional relationships within images. The SimAM module can learn latent vectors highlighting objects or local regions through an energy function using the activation values of neurons and surrounding neurons. The proposed method is a representation learning model that can generate low-dimensional latent vectors from high-dimensional input images, and the latent vectors are binarized into distinguishable hash code. From the experimental results on public datasets such as CIFAR-10, ImageNet, and NUS-WIDE, the proposed model is superior to the comparative model and analyzed to have equivalent performance to the supervised learning-based deephashing model. The proposed model can be used in application systems that require low-dimensional representation of images, such as image search or copyright image determination.

As competition in the airline industry intensifies, effective airline service quality evaluation has become one of the main challenges. In particular, as big data analytics has been touted as a new research paradigm, new research on service quality measurement using online review analysis has been attempted. However, these studies do not use review titles for analysis, relyon supervised learning that requires a lot of human intervention in learning, and do not consider airline characteristics in classifying service quality dimensions.To overcome the limitations of existing studies, this study attempts to measure airlines service quality and to classify it into the AIRQUAL service quality dimension using online review text as well as title based on self-trainingand sentiment analysis. The results show the way of effective extracting service quality dimensions of AIRQUAL from online reviews, and find that each service quality dimension have a significant effect on service satisfaction. Furthermore, the effect of review title on service satisfaction is also found to be significant. This study sheds new light on service quality measurement in airline industry by using an advanced analytical approach to analyze effects of service quality on customer satisfaction. This study also helps managers who want to improve customer satisfaction by providing high quality service in airline industry.

This study has been conducted with $1^{st}$ grade elementary students where the purpose was to develop students' interest in themselves and to cultivate their self-awareness as the first step toward establishing a suitable course and career for their start-up features. Students have conducted the cyber study through "Incheon e-School" and cyber reading "Booktoby" and recorded three types of outcomes - affective self-awareness, social self-awareness and intelligence self-awareness - on each side of the Pyramid, thus constructing their own self-awareness pyramids of the system. According to the results, after such activities were undertaken during the $1^{st}$ semester, their opinion toward their self-control and study ability has improved as much as about 67% compared to that of the beginning of the last semester. Regarding the effects of cyber reading, their interest, spontaneity and understanding toward reading books have also improved as much as 54% and 50%, 33% respectively along with positive answers of as much as 75% with regard to self-awareness. When it comes to the results of the SCI-II test (used to evaluate self-awareness), the total average has improved by as much as 3 points and the three components of self-awareness - affective, social, and intelligence - have improved by as much as 4points, 1point, and 5points, respectively.
