  • The main purpose of this study is to understand how cognitive factors influence the way people interact with information/information systems, by conducting comprehensive and in-depth literature reviews and a theoretical synthesis of related research. Adaptive systems have been built around an individual user's characteristics, such as interests, preferences, knowledge and goals. Individual differences in the ability to use new information and communication technology have been an important issue in all fields. Performance differences in utilizing new information and communication technology are sufficiently predictable that we can begin to coordinate them. Therefore, it is necessary to understand cognitive mechanisms to explain differences between individuals as well as the levels of performance. The theoretical synthesis from this study can be applied to design intelligent (i.e., human friendly) systems in our everyday lives. Further research should explore optimization design for user, by integrating user's individual traits (such as emotion and intent) and system modules to improve the interactions of human-system in data-driven environments.

  • The purpose of this study is to compare and analyze each government's ICT SME support policies to cope with changes in the ICT ecosystem paradigm. In particular, the core policies and policy trends of the Moon's government are presented through keyword network analysis and cognitive map analysis. As a result, core technologies such as ICT(Information Communication Technology), AI(Artificial Intelligence), Big Data, and 5G, which have high values of betweenness centrality and closeness centrality, are major keywords with high propagation power. The cognitive map analysis shows that the opportunity factors for the 4th industrial revolution are being activated through the ICT infrastructure circulation process, the domestic market circulation process, and the global market circulation process. This study is meaningful in terms of cognitive map analysis and utilization based on scientific analysis.

  • This paper explores the language acquisition mechanism within a recent theoretical nativist framework that assumes some computational principles. We will review previous accounts of the logical problem of language acquisition, arguing that language acquisition is part of general cognitive mechanism or at least associated with maturation of cognitive skills. For a theoretical framework, we will adopt the minimalist program and its principles. To support our theoretical argument, we will introduce empirical evidence from ESL (English as a Second Language) and SLI (Specific Language Impairment) data. The two types of data will illustrate that there might be some relationship between the development of language skills and that of the cognitive skills.

  • Objective : The purpose of this study was to examine the level of the cognitive function, and to identify the influencing factors on cognitive function in women cancer patients receiving chemotherapy. This study attempted to provide basic data useful to development of nursing intervention and improve the quality of life in women cancer patients. Methods : As a cross-sectional descriptive study, women with receiving chemotherapy above one cycle were recruited. One hundred and twenty-five women cancer patients who met the study criteria agreed to participate in the study. The questionnaire set consisted of cognitive function, quality of life, depression, anxiety and information on demographic and clinical characteristics. Results : There was no statistically significant difference in clinical characteristics according to the cognitive function. The cognitive function was higher the more low age (F=9.937, p<.001), and the more high education level (F=12.332, p<.001). Multiple regression analysis showed the predictors were significantly related to cognitive function. age, education, and the number of chemotherapy explained 31.8% of the cognitive function. Conclusions : This result of this study provides basic information about factors influencing cognitive function, although study findings are insufficient in explaining related variables among women cancer patients. Even though women cancer patients were receiving chemotherapy, this study showed that the level of cognitive function was high. In order to receive better results and findings the period decreasing cognitive function, further studies are need to measure cognitive function according to the passage of time during or after chemotherapy.

  • The influences of the characteristics of anomalous data on cognitive conflict and conceptual change in learning density were investigated. The subjects were 416 seventh graders. First, the Group Assessment of Logical Thinking and a preconception test were administered. A questionnaire on the responses to anomalous data was then administered. In the questionnaire, four types of anomalous data varying presentation type (movie/text) and authority level (high/low) were randomly presented. After a computer-assisted instruction on density, a conception test was administered. The results indicated that anomalous data presented in movie type significantly induced more cognitive conflict than that in text type. Students presented with anomalous data of high authority scored higher in the conception test than those of low authority. There were no significant interactions between the characteristics of anomalous data and students' logical thinking ability in the scores of both the cognitive conflict and the conception test.

  • The purpose of this study was to examine the types of explanation about different experimental data on students' preconceptions on physical experiment. 45 students were selected from P University by examining their pre-test. The subjects had a scientific conception about a simple pendulum's period of movement, and expected that there was no change in the movement even when the mass of water increased in the can. The students were presented data about pendulum movement inside a can. They recorded this in a blank table and drew a graph about the movement of the pendulum. The responses of students were tested by presenting written anomalous experimental data. Students' recognition, trust about the anomalous data, cognitive conflict, belief change about their preconceptions were examined with written tests also. To measure students' cognitive conflict levels, CCLT (Cognitive Conflict Levels Test) developed in a previous study was used. Some students responded based on preconceptions and regarded the data as manufactured data or experimental error. The students who recognized the anomaly in the situation showed higher cognitive conflict levels than those who didn't recognize the anomaly in the situation. The students who changed their beliefs about preconceptions recognized the data as anomalous situations and showed high cognitive conflict levels than those who didn't abandon their preconceptions. The students who have unchanged beliefs about their preconceptions regarded the data as experimental error.

  • Purpose: The purpose of this study was to identify the effects of the cognitive training program on cognitive function, stress and depression in geriatric hospitals. Methods: The subjects of the experimental group were 17 elderly patients who attended the cognitive training program in Geriatric Hospitals and the subjects of the control group were 15 elderly patients who attended in geriatric hospitals. The persons in training group must take cognitive training program for 4 weeks by 3 times a week. The Mini-mental State Examination Korea version (MMSE-K), Geriatric depression Scaleshort form-Korea version (GDS-K) and Korean Computerized Neurobehavioral Test (KCNT) were utilized to determine cognitive function, stress and depression. The collected data were analyzed by descriptive statistics, t-test and ANOVA using SPSS/PC 12.0 program. Results: Cognitive function (t=-7.625, p=.000) in the elderly after receiving the cognitive training program was significantly more improved than before intervention. Also, Stress and depression (t=2.73, p=.004) was significantly more reduced than before the intervention. Conclusion: This cognitive training program was partially effective in improving cognitive function, neurobehavioral performance and reduce stress and depression. Therefore, it is recommended that this program be used in clinical practice as an effective nursing intervention in geriatric hospitals.

  • Purpose: The purpose of this study is to develop and evaluate the effects of a multifaceted cognitive training program on cognitive function, depression, and instrumental activities of daily living (IADL) in community dwelling elders with mild cognitive impairment. Methods: A non-equivalent control group pretest-posttest design was used. The subjects were recruited from a community health center in D metropolitan city and were assigned to the experimental or control group. Weekly 50-minute session intervention was delivered to the experimental group over 12 weeks. 8 weeks and 12weeks after intervention, the changes in cognitive function, depression, and IADL in the groups were measured and compared. Data were analyzed with Mann-Whitney U test, Wilcoxon Signed Rank test, and post-hoc test with Bonferroni correction using SPSS/WIN 23.0. Results: When compared with their counterparts (n=15), the elders in the experimental group (n=12) showed significant improvement in cognitive function and depression at week 12. The mean scores of IADL at week 12 were not significantly different between the groups. Conclusion: The results indicate that this multifaceted cognitive training program is effective in improving cognitive function, depression, and avoiding deterioration of IADL among elders with mild cognitive impairment.

  • In this study the author examines the health information seeking behavior of older adults from the perspective of cognitive load. Using a qualitative method, based on ground theory, data were collected using in-depth interviews. Twenty-eight participants were participating older adults living in G community city, South Korea who experienced seeking health information. Interview transcripts were analyzed using a qualitative thematic coding framework. Three themes describing older adults' health information seeking behaviors were focused: intrinsic, extraneous, and germane cognitive load. The findings are geared towards the context of older adults' information seeking to support an understanding of successful information seeking behaviors in this population and to contribute to their health and well-being. The intent is to present information on current research in the field of Library and Information Science and to demonstrate how a cognitive load approach can be used to address the problems of older adults' health information seeking behaviors.
