A social network is a typical social science environment with both network and iteration characteristics. This research presents a reaction analysis model of how each node responds to social networks when given input such as promotions or incentives. In addition, the setting value of a specific node is changed while examining the response of each node. And we try to understand the reactions of the nodes involved. The reaction analysis model is constructed by applying various techniques such as unidirectional, fuzzy set, weighting, and cyclic feedback, so it can accommodate the complicated environment of practice. Finally, the implementation model is implemented using Vensim rather than NetLogo because it requires repetitive input, change of setting value in real time, and analysis of association between nodes.

The aim of this study was to investigate the caries management by risk assessment (CAMBRA) development process and the latest updated caries risk assessment for the domestic settlement of the CAMBRA program and the activation of dental clinics. A system for CAMBRA was published in California Dental Association (CDA) in 2007. To investigate whether CAMBRA can be successfully implemented outside a university setting, a practice-based research network (PBRN) was created in the San Francisco Bay Area. Based on the CAMBRA-PRAN clinical studies, the caries risk assessment (CRA) tool was updated for patients aged 6 through adults in 2019. The CAMBRA system is expected to be widely and actively used in the dental field in Korea to contribute to oral health care.

Over the past three decades, services have become the largest part of most industrialized nations' economies but it is the least-studied part of the economy. One approach is to develop a general theory of service with well-defined questions, tools, methods, and practical implications of society. The purpose of this study was to propose a service systems model to systematically approach a service research. For this purpose, we conducted literature review about business model and extant service systems researches. Based on a literature review, we propose a service systems model that comprises value proposition, participants, shared information/knowledge, organizational capability, value network, and technology. Implications for practice and recommendations for additional research were discussed.

Recently, in the global financial transaction field, global transactions using computer systems and server hubs between foreign exchanges beyond the one-dimensional offline transactions and two-dimensional online transactions have been actively conducted. In the previous research by Lee Hyung-wook and Lee Min-jae (2018), as the globalization has accelerated following the development of digital technology and the expansion of ubiquitous communication network, the role of companies, the attribute of economic value creation and economic structure are being reorganized. It is said that O2O (Online to Offline) transactions are increasing due to the development. As a result, a new financial transaction paradigm is emerging that solves the inconveniences of existing financial services and enhances speed and convenience. Considering the global network trend and the rapidly developing and evolving digital bank environment, the necessity of utilizing the business platform model is emerging. However, despite this necessity, there are very limited cases in which such an attempt has been applied in practice. Accordingly, this study seeks to explore the business platform of the new financial transaction system. Specifically, the case study systematically examines the actual implementation of a unique network connection model with Koscom's global investment bank, which is currently in charge of the domestic financial transaction system, and improves ICT innovation performance and process through this. I would like to suggest a solution. In particular, this study analyzed a variety of business model construction and use cases by pursuing a platform connection with digital banks, which has recently been increasingly in demand. Therefore, this study intends to pursue the original and long-term profitability of the company by utilizing ICT innovation and platform business model, and also analyzes the convenience and excellence of trading for institutional and individual investors using the platform of digital bank. The implications of this study are significant in that it explores and explores the actual cases of ICT innovation and additional digital bank platform-connected business models based on this, and suggests a unique and preemptive business strategy of the company in the future.

Art education in design has repeatedly stressed the importance of developing creativity. In the digital period, however, which shows rapid change in both forms and contents, it needs to be equipped with more flexible and systematic ways of approaching to the creativity development, especially involved with cultural diversity of the digital world. This paper primarily proposes a maximally efficient, productive creativity learning program in which the integration of expressive media and communication generates a comprehensive network of communicative information in the development of digital technologies, which, consequently, brings forth valuable cultural contents of art. The amalgamation of Won (2006)'s Prism Effect, with distinctive three devices, and the facilitator factors, with two different facilitators such as self-controlled and controlled plays, would function as a catalyst for cultural diversity in the digital forms and contents of art. And this will, consequently, result in producing a number of practices that can be classified and assorted for a later performance. This paper thus suggests a roadmap of how to develop the creativity learning program in which two categories of facilitators based on three thinking devices function to classify four activities. In addition, selected activities are shaped as a creativity learning program by generating learning practices with the formalizing instructional strategy that fit into a specialized educational environment and learners. The samples of loaming practice design show guidelines for practice and the results of learning activity. Therefore, the eventual goal of this paper would be to establish a creativity learning program that constitutes a highly systematized and modularized database to maximize the efficiency and productivity of the creativity development.

The author recommends the creation of a nationwide career guidance program at the national level through the establishment of a long-term cohort, involving collaboration among medical schools nationwide. This cohort would be constructed for the purpose of analyzing correlations from admission to medical school to post-graduate education, facilitating the development of a career guidance program. This will aid in career development through students' self-analysis and competency building. Each medical school should operate a systematic career guidance program. Career guidance for post-graduate major selection should be included in the regular curriculum. Schools are advised to operate student counseling rooms for various career guidance services. For example, medical schools can operate 1:1 career counseling, academic counseling, career guidance surveys, psychological tests, and counseling. It is advisable to establish a mentor-professor system, connect mentor professors, and build a network of experts related to majors to provide immediate support according to students' needs. Professional mentor training should be provided to mentor professors. To provide opportunities for students to experience their career paths in advance, early clinical exposure, long-term integrated clinical practice, community-based clinical practice, participation in student research programs, career fairs, and student internship programs are recommended. In South Korea, it is necessary to systematically operate the internship system and make improvements to facilitate optical career choices. Additionally, considering the significant influence of social factors on students' career choices in South Korea, efforts should be made to identify and address the issues related to these social factors.

Quality design in practice highly depends on human designer's intuition and past experiences due to lack of formal knowledge about the relationship among 10 variables. This paper represents an data mining approach for developing quality design support system that integrates Case Based Reasoning (CBR) and Artificial Neural Networks (ANN) to effectively support all the steps in quality design process. CBR stores design cases in a systematic way and retrieve them quickly and accurately. ANN predicts the resulting quality attributes of design alternatives that are generated from CBR's adaptation process. When the predicted attributes fail to meet the target values, quality design simulation starts to further adapt the alternatives to the customer's new orders. To implement the quality design simulation, this paper suggests (1) the data screening method based on ξ-$\delta$ Ball to obtain the robust ANN models from the large production data bases, (2) the procedure of quality design simulation using ANN and (3) model management system that helps users find the appropriate one from the ANN model base. The integration of CBR and ANN provides quality design engineers the way that produces consistent and reliable design solutions in the remarkably reduced time.

Purpose: To describe technical methods for functional magnetic resonance imaging (fMRI) study with arterial spin labeling (ASL) compared to blood oxygenation level-dependent (BOLD) technique and discuss the potential of ASL for research and clinical practice. Materials and Methods: Task-based (n = 1) and resting-state fMRI (rs-fMRI) (n = 20) were performed using ASL and BOLD techniques. Results of both techniques were compared. Results: For task-based fMRI with finger-tapping, the primary motor cortex of the contralateral frontal lobe and the ipsilateral cerebellum were activated by both BOLD and ASL fMRI. For rs-fMRI of sensorimotor network, functional connectivity showed similar results between BOLD and ASL. Conclusion: ASL technique has potential application in clinical and research fields because all brain perfusion imaging, CBF measurement, and rs-fMRI study can be performed in a single acquisition.

Objectives: As collaboration for community health promotion is much emphasized, the concept and process of community collaboration for health needs to be discussed. This paper discusses varying types of collaboration and collaboration building processes and suggests directions for enhancing community collaboration research and practice. Methods: Leading literature on community partnership building and community health development and current community partnership research program information were reviewed. Results: Although the term collaboration is used interchangeably with cooperation, partnership, network, or coalition, conceptual differences need to be acknowledged in order to develop and reinforce the processes of collaboration. Collaboration building goes in hand with community-based participatory research and systems thinking, which should be supported by long-term, systematic planning and evaluation research. Conclusion: Collaboration for community health promotion needs to be defined and agreed conceptually, thus collaboration process can be developed. Effective collaboration building will be facilitated by systematic thinking and participatory research. Research support system should appreciate the time-intensive, process-oriented nature of collaboration building by providing long-term research funding and emphasizing process and long-term evaluation.
