A critique of Korean National Information Strategy: Case of national information infrastructures

In 2004, the Korean government launched the IT839 project with the objective of converting Korea into a ubiquitous information society. This study investigates the role of the Korean government in the development of the national information infrastructure and the realization of IT839 vision. This paper reviews the historic and individual data related to the infrastructure project, draws on the social construction of technology theory as a framework for interpreting such data, traces the transformations and translation of this data in the public, political, and social discourse, and discusses the next generation of information infrastructure. Findings imply that despite optimistic prospects and proactive drive, uncertainty still remains with respect to where IT839 will evolve and how it will impact the new information milieu.     

Attending to Diversity Representation Among Council for Accreditation of Counseling and Related Educational Programs (CACREP) Master’s Programs: A Pilot Study

Extant research has neglected to explore the diversity representation of counselor education programs. This pilot study sought to examine the extent to which CACREP-accredited master’s-level programs attend to the representation of people of color, individuals with dis/abilities, lesbian, gay, bisexual (LGB), and transgender persons within admissions, enrollment, and graduation data. The findings indicated little consistency in the maintenance of students’ demographic characteristics among participating programs. The authors contend that counseling programs need to critically analyze their policies and procedures to ensure a responsive milieu for students from diverse backgrounds. Implications for the counseling field are presented.     

A living lab as socio-technical ecosystem: Evaluating the Korean living lab of internet of things

Living Lab approaches, as one of socio-technical approaches, are effective strategy for user-driven technology development. The recent development of the Internet of Things (loT) and its various technologies appear to be promising possibilities to adopt Living Lab innovation into community domains. Using Living Lab frame, this study examines the developmental processes of the IoT from a multi-level analysis: a micro approach of user acceptance and experience of IoT services; a meso approach of socio-technical evaluation of selected site; and a macro approach of regulation and strategies on IoT. Through the multi-level approach, it conceptualizes a Living Lab process to create, test, and adept a social IoT environment. The findings should guide governments' promotion of IoT services to increase user acceptance by enhancing usability and benefits and ensuring sustainability. The findings also provide guidelines, strategies, and best practices for practitioners to integrate IoT into communities and society effectively. The insights help to conceptualize how the IoT can be situated and contextualized within human-centered contexts. The results of this study show that creating IoT innovations require prudent coordination of different stakeholders and roles across innovation cycle. Particularly user-centered approach warrants a new innovative way to structure and facilitate user involvement within the context of Living Labs for IoT.     

Cultural validation of the Maslach Burnout Inventory for Korean students

The purpose of this study was to examine the factorial validity of the MBI-SS in Korean students. Specifically, we investigated whether the original three-factor structure of the MBI-SS was appropriate for use with Korean students. In addition, by running multi-group structural equation model analyses with factorial invariance tests simultaneously for both genders (i.e., males and females) and academic settings (i.e., middle school and high school), we tested whether the factor loading and correlations between factors can be similarly interpreted across the different groups. Results indicated that the MBI-SS is a valid instrument to measure academic burnout of Korean students. Furthermore, results presented the possibility that the MBI-SS could be used regardless of cultural background. Implications for future research and practice and limitations are discussed.     

Contribution of hand and foot force to take-off velocity for the kick-start in competitive swimming

This study examines the hand and foot reaction force recorded independently while performing the kick-start technique. Eleven male competitive swimmers performed three trials for the kick-start with maximum effort. Three force platforms (main block, backplate and handgrip) were used to measure reaction forces during starting motion. Force impulses from the hands, front foot and rearfoot were calculated via time integration. During the kick-start, the vertical impulse from the front foot was significantly higher than that from the rearfoot and the horizontal impulse from the rearfoot was significantly higher than that from the front foot. The force impulse from the front foot was dominant for generating vertical take-off velocity and the force impulse from the rearfoot was dominant for horizontal take-off velocity. The kick-start’s shorter block time in comparison to prior measurements of the grab start was explained by the development of horizontal reaction force from the hands and the rearfoot at the beginning of the starting motion.     

A review on 3D printing functional brain model

Modern neuroscience increasingly relies on 3D models to study neural circuitry, nerve regeneration, and neural disease. Several different biofabrication approaches have been explored to create 3D neural tissue model structures. Among them, 3D bioprinting has shown to have great potential to emerge as a high-throughput/high precision biofabrication strategy that can address the growing need for 3D neural models. Here, we have reviewed the design principles for neural tissue engineering. The main challenge to adapt printing technologies for biofabrication of neural tissue models is the development of neural bioink, i.e., a biomaterial with printability and gelation properties and also suitable for neural tissue culture. This review shines light on a vast range of biomaterials as well as the fundamentals of 3D neural tissue printing. Also, advances in 3D bioprinting technologies are reviewed especially for bioprinted neural models. Finally, the techniques used to evaluate the fabricated 2D and 3D neural models are discussed and compared in terms of feasibility and functionality.     

Density-dependent separation of encapsulated cells in a microfluidic channel by using a standing surface acoustic wave

This study presents a method for density-based separation of monodisperse encapsulated cells using a standing surface acoustic wave (SSAW) in a microchannel. Even though monodisperse polymer beads can be generated by the state-of-the-art technology in microfluidics, the quantity of encapsulated cells cannot be controlled precisely. In the present study, mono-disperse alginate beads in a laminar flow can be separated based on their density using acoustophoresis. A mixture of beads of equal sizes but dissimilar densities was hydrodynamically focused at the entrance and then actively driven toward the sidewalls by a SSAW. The lateral displacement of a bead is proportional to the density of the bead, i.e., the number of encapsulated cells in an alginate bead. Under optimized conditions, the recovery rate of a target bead group (large-cell-quantity alginate beads) reached up to 97% at a rate of 2300 beads per minute. A cell viability test also confirmed that the encapsulated cells were hardly damaged by the acoustic force. Moreover, cell-encapsulating beads that were cultured for 1 day were separated in a similar manner. In conclusion, this study demonstrated that a SSAW can successfully separate monodisperse particles by their density. With the present technique for separating cell-encapsulating beads, the current cell engineering technology can be significantly advanced.
