This study analyzed the contents of Goodreads review data, which is a social cataloging service with the participation of book users around the world, to identify the preference factors that affect book users' book recommendations in the library information service environment. To understand user preferences from a more detailed point of view, sub-datasets for each rating group, each book, and each user were constructed in the sample selection process. Stratified sampling was also performed based on the result of topic modeling of review text data to include various topics. As a result, a total of 90 preference factors belonging to 7 categories('Content', 'Character', 'Writing', 'Reading', 'Author', 'Story', 'Form') were identified. Also, the general preference factors revealed according to the ratings, as well as the patterns of preference factors revealed in books and users with clear likes and dislikes were identified. The results of this study are expected to contribute to more sophisticated recommendations in future recommendation systems by identifying specific aspects of user preference factors.

The open inquiry is one of the representative learning approaches for gifted students. However, a gifted student should develop various complicated competencies to succeed in the open inquiry because of its complexity. This study develops a question list in accordance with each stage of inquiry so that the list could provide scaffolding in the process of open inquiry and students develop near-professional competencies and produce distinguished outcomes. For the purpose, we have reviewed various literatures related to research methodologies, academic writings, and learning of inquiry. Based on the review, we identified the open inquiry as cognitive, metacognitive, and sociocultural processes and set up the direction of the development of the question list. We also have elaborated the goals of the open inquiry, provided a model of the stage of inquiry, and developed the guiding question list belonging to each stage. As a discussion, we provided several noteworthy issues in the situation of when the list is used in the teaching of the open inquiry for the gifted.

In physics education, language is an fundamental learning tool as in other subjects. In writing activity, students can get fair opportunities to express their own ideas during the class. Even though there are various styles of writing, students are usually supposed to make a report in their science classes. But there have been few studies in science education on the tasks and features of student's science writing. In this research, different styles of writing tasks were designed for science classes, and students' writing was analysed in terms of conceptual and emotional aspects. Also the usefulness of each task type was discussed relating to school physics education. Four types of writing, i.e. , , , and writing were developed, and 'The reflection of light' was selected as the theme and given to students. Four types of writing were analysed in this paper. In each type of writing, students showed different features in their conception. They also showed emotional expressions in imaginative writing types, that is, and types. Based on these results, it is recommended that in physics teaching various types of writing need to be designed, developed and applied according to the aim of a particular lesson.

Objective : The purpose of this study was to identify the effect of crafts and handwriting on bilateral coordination during task performance. Methods : Randomly selected 30 college students without hand disability were invited for the study, and grouped 3(test group 1 for crafts, test group 2 for handwriting, and control group) with 10 students per group respectively. Then Jebsen-taylor hand function test, Purdue pegboard test, and Minnesota manual dexterity test were employed for evaluating changes before and after the intervention. Results : After training intervention of crafts and handwriting for two test groups, test groups showed better bilateral coordination significantly than the control group. Especially test group 1(crafts) showed a bigger difference at Jebsen-taylor hand function test, and likely test group 2(handwriting) did at Purdue pegboard test. Conclusion : It was found that crafts increase bilateral coordination, while handwriting increase hand dexterity during task performance. That is, crafts and handwriting affect tasks differently. Further studies applying various crafts and handwriting for many age groups will be helpful for identifying the better way of occupational intervention for individuals in lack of bilateral coordination.

The study investigated undergraduates' citation use and plagiarism awareness. A questionnaire method was used and was given to undergraduates in a university located in Seoul. Upon investigation, undergraduates recognized the importance and the need of citation and were partly applying citations. However, upon further investigation of undergraduates' citation learning with citation questions, very few of respondents had knowledge of correct citation usage. Undergraduates mostly cited print materials and information from the internet. They used books in case of print materials and web materials provided by academic institutions. They suggested that the university should teach citation usage through a citation and plagiarism awareness program. It is necessary for library use education (information literacy education) as well as university to teach citation education including citation type and how to write it.

This study examined the relationships and characteristics between generic skills and individual variables. The data from 187 students at a Korean university that participated in the Assessment of Higher Education Learning Outcomes (AHELO) feasibility study were utilized. The results indicated that there were no differences in generic skills according to gender, age, and grade point average (GPA). The field of study was the only variable showing a statistically significant difference in generic skills among the three groups. As a result of cluster analysis, four groups were formed based on the characteristics of generic skills. No differences in generic skills were observed among the four groups according to gender, age, and field of study. On the other hand, there was a statistically significant difference in generic skills among the four groups according to the GPA.

Recently, various AI chatbots based on large language models have been released. Chatbots have the advantage of providing users with quick and easy information through interactive prompts, making them useful in various fields such as question answering, writing, and programming. However, a vulnerability in chatbots called "prompt injection attacks" has been proposed. This attack involves injecting instructions into the chatbot to violate predefined guidelines. Such attacks can be critical as they may lead to the leakage of confidential information within large language models or trigger other malicious activities. However, the vulnerability of Korean prompts has not been adequately validated. Therefore, in this paper, we aim to generate malicious Korean prompts and perform attacks on the popular chatbot to analyze their feasibility. To achieve this, we propose a system that automatically generates malicious Korean prompts by analyzing existing prompt injection attacks. Specifically, we focus on generating malicious prompts that induce harmful expressions from large language models and validate their effectiveness in practice.

Psychological research on the relationships between creativity and knowledge can be divided into two main streams, called tension view and foundation view. However most of the studies in this area have been too much focused on creative products which had a limit in investigating creative processes. In this study, to identify the relationships, we employed neuro-scientific approaches to investigating EEG (electroencephalogram) activity from professional computer programmers(n=10). Also the EEG alpha TRP (task related power) was compared with each other. The procedures including resting conditions with eye closed were followed by ordinary thinking process, creative thinking processes in a professional domain and a nonprofessional domain. As a result of EEG activity analysis, alpha deactivation was observed mainly in temporal lobe, especially in left-temporal lobe during creative thinking process of professional domain. The findings suggest that neuro-scientific approach supports the tension view, suggesting that the knowledge could hinder creativity.

In this study, we focused on the socio-structural factors that cause ageism, investigating whether the influence of the resource scarcity on ageism in the younger generation depends on socioeconomic status. To test this hypothesis, we conducted an online study of 219 adults in their 20s and 30s. Specifically, participants were randomly assigned to either the resource scarcity priming condition or the control condition, and completed a writing task. After this, participants responded to ageism and socioeconomic status items. As a result, the effect of resource scarcity on ageism was not significant. However, we found that socioeconomic status moderated the impact of resource scarcity on ageism. In other words, resource scarcity priming has been shown to significantly reduce ageism for individuals who have relatively lower socioeconomic status. This finding is in line with previous studies in which people of low socioeconomic status were found to be more sympathetic to socially disadvantaged individuals suffering deleterious situations such as resource scarcity. This work is significant in that we have looked at both the situational and personal factors influencing ageism, and in that we have attempted to examine the causal influence of resource scarcity on ageism through an experimental approach. However, since the alternative explanation of the findings has not been completely excluded, replication through further studies will be necessary.
