Human decision-making is a complex behavior. A replication of human decision making offers a potential to enhance the capacity of intelligent systems by providing additional user assistance in decision making. By reducing the effort and task complexity on behalf of the user, such replication would improve the overall user experience, and affect the degree of intelligence exhibited by the system. This paper explores individuals' decision-making processes when using recommender systems, and its related outcomes. In this study, human decision-making (HDM) refers to the selection of an item from a given set of options that are shown as recommendations to a user. The goal of our study was to identify IS constructs that contribute towards such decision-making, thereby contributing towards creating a mental model of HDM. This was achieved through recording Electroencephalographic (EEG) readings of subjects while they performed a decision-making activity. Readings from 16 righthanded healthy avid readers reflect that reward, theory of mind, risk, calculation, task intention, emotion, sense of touch, ambiguity and decision making are the primary constructs that users employ while deciding from a given set of recommendations in an online bookstore. In all 10 distinct brain areas were identified. These brain areas that lead to their respective constructs were found to be cingulate gyrus, precentral gyrus, inferior parietal lobule, posterior cingulate, medial frontal gyrus, anterior cingulate, postcentral gyrus, superior frontal gyrus, inferior frontal gyrus, and middle frontal gyrus (also referred to as dorsolateral prefrontal gyrus (DLPFC)). The identified constructs would help in developing a design theory for enhancing user assistance, especially in the context of recommender systems.

Purpose: The purpose of this study was to identify post-operative discomfort, sense of loss, family support, and resilience in breast cancer surgery patients, and to investigate factors that affect resilience. Method: The sample of this study consisted of 108 patients who underwent surgery for breast cancer in two university hospitals located in B city. The collected data was analyzed with descriptive statistics, t-test, ANOVA, and Scheffé test, Pearson's correlation coefficients, and hierarchical multiple regression. Results: The factors that significantly affected resilience were as follows: having a religion (${\beta}=-.20$, p=.006), having an occupation (${\beta}=.14$, p=.049), having a high school diploma (${\beta}=.31$ p=.001), making less than 2-3 million won (${\beta}=-.19$, p=.036) per month, experiencing a sense of loss (${\beta}=-.22$, p=.003) and family support (${\beta}=.44$, p<.001). The total explanatory power amounted to 53.8% (F=14.83, p<.001, $AdjR^2=.54$). Conclusion: Educational intervention programs for breast cancer surgery patients that improve resilience by reducing the sense of loss and increasing family support must be developed.

With the development and spread of 3D display, users can easily experience an augmented reality with 3D features. Therefore, the demand for content of an augmented reality is exponentially growing in various fields. A traditional augmented reality environment was generally created by CG(Computer Graphics) modelling production tools. However, this method takes too much time and efforts to create an augmented environment. To create an augmented environment similar to the real world, everything in the real world should be measured, gone through modeling, and located in an augmented environment. But the time and efforts spent in the creation don't produce the same environment as the real world, making it hard for users to feel the sense of reality. In this study, multi-scale 3D panorama content augmented system is suggested by using a depth-map. By finding matching features from images to add 3D features to an augmented environment, a depth-map is derived and embodied as panorama, producing high-quality augmented content system with a sense of reality. With this study, limits of 2D panorama technologies will be overcome and a sense of reality and immersion will be provided to users with a natural navigation.

Future war needs a lot of changes for military organization. Specially, concept of the "Speed" is raised importantly after Iraq war of U.S. Armed Forces. So, He is a lot of studying supply chain for logistical support speed improvement. Korea Marine Corps has made an efforts to improve supply chain. However it is real that is putting various techniques by prescription rather than fundamental change. These simplicity prescriptions are not only systematic but also insufficient for Marine Corps' survival. In addition, Korea marine corps in actuality is depending on many members in marine and navy in feed chain. Thus it is not establishing even tactical, decision-making plan of operation for support ability cultivation. Therefore, in this study, with Sense and Response concept that is United States Marine Corps' support strategy, presented theoretical background and basis frame that serve that Korea Marine Corps's supply chain changes to perception reaction formation.

In the 21th century, the age of image, people express and evaluate with images. Image is a symbol of a person or a thing. It simulates people's visual sense most quickly and precisely and is shared in the society. At the time, since it is acknowledged that there are few books available and lack of theoretical system with regard to image making, the purpose of this study was to get a theoretical access to image making by taking as an empirical case the case of Choi Byeongryeol, a candidate running for the congress in June 4, 1998 and combining it with theories of costume. Research methods employed here were to investigate the theoretical system of image making and fashion direction, and to analyze empirical cases. The boundary of the empirical case was limited to the candidate's fashion direction during the election period for 50 days from April 1998 to the election date June 4, 1998. The results of this study are as follows. First, personal image making aims at the establishment of one's own identity through building up an ideal image. Second, it is found that personal image making can make a complete image possible through fashion direction. Third, it is found that fashion direction functions as a symbol and communicative means with a result that the effect can penetrate to the society accurately and quickly. Fourth, it is found that fashion direction fit for a situation can enhance personal values and reinforce his or her competitive power to carry out the ultimate goals in the society. This study proved that fashion styling for personal image making expresses a person in a symbolic image, enhances his/her personal value in the society and, ultimately, contributes to the establishment of an individual's identity.

This paper aims to explore the analysis of the meanings and processes of reading online consumer reviews and to construct a substantive theory that explains the process involved with the phenomenon of reading consumer reviews. In order to explore the phenomenon, this study employs a qualitative methodology. Following the grounded theory perspective, the researcher conducted interviews with 17 participants, who have subsequently shopped online and utilized online consumer reviews for shopping, and decidedly employed in-depth interviews with those participants. Through coding and making constant comparison, several themes emerged: improving confidence, trusting reviews, getting a sense of who reviewers are, seeking balance, processing and handling negative reviews, experiencing vicariously, increasing searchability, getting a sense of who they are in terms of similarity, and seeking benefits and the usage situations from consumer based reviews. Among the emerging themes, improving confidence can be considered a core category, which is influenced by the analysis of trusting reviews and the consumer vicarious experiences with a product. Moreover, this study discusses the relationships among the themes. This study concludes with a discussion of the results, implications, and limitations.

The purposes of the study are to portray Korean beginning secondary science teachers' ways of arranging science content, sense-making strategy, and factors contributing to the tensions between teachers' intentions and actual practice. Six beginning secondary science teachers participated in this study. Science classes taught by the participating teachers were observed and videotaped. Semi-structured interviews were conducted for science teachers participated in this study after science classes were observed. Instructional materials were also collected for each science class. Video- and audio-taped data were transcribed and analyzed using conceptual framework developed by the Michigan State University. The findings of this study produce the following conclusions: (1) beginning teachers' science classes are arranged in ways compatible to traditional school science, (2) frequently used sense-making strategies are procedural display and narrative reasoning, (3) tensions between beginning teachers' intentions and practice arise from two factors such as assessment and differences in educational views with peer teachers, and (4) learning experiences, lack of perceptions and preparations on reform science teaching, and the absence of systematic program for professional development programs for beginning science teachers are major obstacles to reform science teaching for beginning teachers.

Universities that previously targeted in 20s have recently diversified their operation methods, founding purposes, and target. With a significant decrease in the school-age population relative to the number of universities, universities are making their best efforts to secure new students and minimize student attrition. In this study, an online survey was conducted to empirically examine the effects of motivation for major selection and sense of belonging on learning persistence intention among students in beauty-related departments at 2-year and 4-year general universities and cyber universities. The collected data from 119 students at general universities and 113 students at cyber universities were analyzed using SPSS 28. The key findings can be summarized as follows: For general universities, motivation for major selection did not have a significant effect on learning persistence intention, but sense of belonging had a significant positive effect. Additionally, an interaction effect was observed, indicating that as the sense of belonging increased, extrinsic motivation significantly increased learning persistence intention. For cyber universities, intrinsic motivation and sense of belonging among motivations for major selection had a significant positive effect on learning persistence intention, while the moderating effect of sense of belonging in the relationship between motivation for major selection and learning persistence intention was not significant. In summary, for general universities, the factor that influenced students' learning persistence intention was a sense of belonging to the university, while for cyber universities, intrinsic motivation played a significant role. These findings are expected to provide meaningful insights and data for universities to develop effective policies for preventing student attrition.
