Based on Artificial Intelligence technology, AI-enabled warfare is expected to become the main issue in the future warfare. Natural language processing technology is a core technology of AI technology, and it can significantly contribute to reducing the information burden of underrstanidng reports, information objects and intelligences written in natural language by commanders and staff. In this paper, we propose a Language model-based Multi-source Information Integration (LAMII) framework to reduce the information overload of commanders and support rapid decision-making. The proposed LAMII framework consists of the key steps of representation learning based on language models in self-supervsied way and document integration using autoencoders. In the first step, representation learning that can identify the similar relationship between two heterogeneous sentences is performed using the self-supervised learning technique. In the second step, using the learned model, documents that implies similar contents or topics from multiple sources are found and integrated. At this time, the autoencoder is used to measure the information redundancy of the sentences in order to remove the duplicate sentences. In order to prove the superiority of this paper, we conducted comparison experiments using the language models and the benchmark sets used to evaluate their performance. As a result of the experiment, it was demonstrated that the proposed LAMII framework can effectively predict the similar relationship between heterogeneous sentence compared to other language models.

The objective of this study was to determine the effects of simulation education with problem-based learning (SIM-PBL) on information literacy, self-directed learning ability, and academic self-efficacy of nursing students. The subjects were 81 fourth-year nursing students attending a university in Chungcheongnam-do, Korea. SIM-PBL was provided once per week (150 minutes each) for four weeks, and a structured questionnaire was used to survey information literacy, self-directed learning ability, and academic self-efficacy before and after educational training. After completing the four-week program, abilities in the sub-items of information literacy, such as information integration (${\acute{p}}=.030$), information expression (${\acute{p}}=.003$), and information ethics (${\acute{p}}=.016$) were improved. However, no differences in self-directed learning ability and academic self-efficacy were noted. Findings confirmed that SIM-PBL is an effective teaching method for improving the information literacy of nursing students. Therefore, it is necessary to come up with an SIM-PBL education plan for utilizing reliable and useful information ethically.

This study aims to demonstrate the importance of information literacy instructions by showing effects of information literacy skills on critical thinking dispositions among high school students. We collected 761 survey responses from high school students and conducted multiple regression analysis to examine the relationships between the two variables. The findings show that (1) students' information search skills affect their pursuit of truth, openness, inquiring mind, and objectivity, (2) the information analytic skills influence the levels of pursuit of truth, openness, and objectivity, (3) the information presentation and delivery skills affect the levels of inquiring mind, organization, and self-trust, and, (4) the information evaluation skills influence the levels of pursuit of truth, openness, inquiring mind, organization, objectivity, and self-trust. However, students' synthesis and application skills of students did not affect their critical thinking dispositions. To sum up, we observed the influence of information literacy skills on critical thinking dispositions. The results of this study provide foundations for maintaining and developing information literacy instructions in school libraries.

This study identifies key determinants of participation in UCC services. Incorporating insights from the flow theory, we examine the effects of psychological factors of social presence, self expression, arousal, and challenge as well as web-site characteristics variables of media easiness, contents usability, and immediateness. We have done a sample survey of internet users and collected 260 responses. Using Windows SPSS/PC 12.0 Package, we have performed statistical analyses including a correlation analysis, a factor analysis, and a multiple regression analysis. The result of the study is as follows. Psychological variables of perceived social presence, self expression, arousal, and challenge all show positive significant effect on participation in UCC service. Among web site characteristics, media easiness, which consists of a web structure that is easy-to-use, user friendliness, and personalized service, demonstrates a positive significant effect on participation in UCC services. Immediateness also has a positive significant effect. Some of the practical implications of the result are follows. We should improve user access to platforms of UCC service by opening up platforms. This will heighten perceived challenge which has the strongest influence on participation in UCC services. We need to focus on multimedia services and adjust to the cultural code of netizen who crave for visual expressions and on the spot on-line activities. Also suggested is that contributions made by participants need to be acknowledged through such provisions as profit sharing. Needs for individualized service, which is an aspect of media easiness, should also be addressed. Participants tend to value individuality while at the same time accepting broader trends. Information services need to be customized for individuals. In UCC centered internet businesses, netizen consumers are presumer. They are consumers and producers at the same time, and consumer needs should also be explored for the success of internet businesses.

We reviewed existing studies and proposed future research on the sustainability of short-term effects, and of the Yongin Emotion Management Training program (Y-EMT). In this study, we conducted Y-EMT to verify its effectiveness in relation to affective disorders associated with chronic schizophrenia. Thirty-five patients were assigned to the experimental group, and 35 to the control group. First, results of repeated-measures analysis supported the effectiveness of Y-EMT. Comparisons of the results on the pre-test with those for the 5-month and 1-year post-training tests showed significant differences in mean scores between the experimental and control groups. Furthermore, these differences persisted at the 2-year follow-up. Second, in the experimental group, interactions between emotional behavior and expression, self-efficacy, and changes in interpersonal relationships showed significant effects at 5 months after the program ended, and these effects continued to increase up to 1 year post-training. Taken together, the findings indicate that, to maintain the effects of therapy in patients with chronic schizophrenia, patients should undergo Y-EMT along with cognitive rehabilitation training and social skills training. Human relations training such as Y-EMT is most helpful for rehabilitation when it is paired with high levels of medication.

The number of single-parent families in South Korea increased since 2000, related to a sharp rise in the divorce rate of 50s and an increase in male mortality rates among those aged 40s-50s. Middle-aged single mothers experience a critical period realizing self-actualization needs, while being in the middle adulthood from the lifespan developmental perspective. In this respect, it is significant to study self-actualization of middle-aged single mothers through guided imagery and music (GIM) in order to provide them with psychological support. This study was conducted from September 2018 to June 2020, and the GIM sessions were conducted at least 10 times. Four participants were selected among the middle-aged single mothers. The imagery experiences of participants in the GIM sessions were classified into four sub-elements: physicalness, emotion, memory, and sense. Within those sub-elements, eight semantic units were categorized into 46 elements. Finally, 152 semantic units were derived. Moreover, the self-actualization which participants experienced through GIM presented three archetypal images: shadow, persona, and the self. In the GIM sessions, experiences of putting their negative emotions associated with family into words and changing passive self-imagery into active one enabled participants to bring the shadow into their consciousness, there by recognizing their positive and bright internal self. Furthermore, participants could map that their current status as people marginalized by siblings and parents, enraged and holding double standards for others, was suppressed by their 'good daughter' and 'religious' personas. This realization lead them to realize and restore their persona. The use of GIM in the study allowed participants to elicit re-experiences of the negative events, while experiencing various imagery and music. This process helped participants achieve self-actualization.

A numerical investigation to simulate the selective growth of silicon-germanium quantum-dots via local surface diffusivity enhancement is presented. A nonlinear equation for the waviness evolution of film surface is derived to consider the effects of spatially-varying diffusivity, influenced by a surface temperature profile. Results show that the morphology of the initially planar film shapes into an undulated surface upon perturbation, and a steady-state solution describes a fully grown quantum-dot. The present study points toward a fabrication technique that can obtain selectivity for self-assembly.

With the recent trend of Web 2.0, experts argue that the UCC age has blossomed where people themselves produce their own content and share it on the Internet. However, more academic studies on video UCC production are needed to understand fully the video UCC phenomenon in Korea. This study was done as an exploratory study to investigate the motivations for video UCC production and its effects. Results reveal that the important motivations for participating in video UCC creation are fun, sharing, and self-expression. For the rewards for video UCC creation participation, feedback, sharing and self-satisfaction are considered valuable psychological rewards by the video UCC creators. Furthermore, the total amount of video UCC production is positively correlated with self-evaluation of fun, importance, and practicality of the video UCC content.

This study critically examines the social and personal meanings that luxury consumption have in contemporary Korean society through understanding the consumption experiences of men in their 30s. Interviews with nine male consumers who are committed to luxury brands, especially those that produce suits, watches, fountain pens, and shoes, were conducted to collect qualitative data. We found that participants are satisfied with the whole process of luxury brand consumption including buying, using, and managing and try to consume the products for self-expression, congruent with their lifestyle and identity. Individuals have learned how to consume the luxury brand from their role models. Their consumption follows hybrid and postmodern patterns and combines luxury brand products with non-luxury one. In contemporary Korean society, using the luxury products is considered necessary to achieve some advantages in social contexts and can be also functioned as a sort of social signifier and self-help, as well as, a tool for self satisfaction or well-being.
