Of all the 55 security departments in colleges, the information security departments occupies the majority of 45. Though existing security focused too much on information security, a new research stream on industrial security from a perspective of convergence has emerged. Since the first department of industrial security was established in a college in 2014, the total of four departments have been established until 2018. A new discipline to solve the existing problems and an opportunity to cultivate industrial security professionals have been greatly appreciated; however, the definition of industrial security is not yet specific, and more discussions on education categories and subjects with a focus on the characteristics of convergence are needed. The demand for industrial security professionals has gradually increasing and the departments of industrial security have been established to meet the demand. It is necessary, in this circumstance, to find out how the industrial security departments are teaching students. To this end, the purpose of this article is to deliver an overview of the educational curriculums of the four industrial security departments. This study analyzed 127 subjects in the curriculums, categorized educational areas, and employed Social Network Analysis to understand the relationships between subjects of each departments.

This study, as an attempt to integrate mathematics and information for convergence education, was conducted to develop teaching-learning materials on mathematics education combined with coding education, which has recently been emphasized. We chose the subject of digital signature for coding education, and used SageMath as a coding program. In this study, we overview mathematics used in the elliptic curve digital signature algorithm, one of the many methods for digital signature, and developed the teaching-learning materials on the algorithm for mathematics education integrated with information education based on coding. The elliptic curve digital signature algorithm utilized in transactions of Bitcoin, which many people recently are interested in, is a good example, showing students that mathematics is applied to problem-solving in the real world and provides an optimal environment for implementation by coding. Accordingly, we expect that a class on algorithm will provide a specific teaching-learning program to achieve the goal of integrated mathematics education. By comprehensively considering the opinions of mathematicians, mathematics teachers and mathematics education experts, we expect that the teaching-learning program will be realized as a meaningful class in science high schools, high school's math clubs, and 'number theory' class in colleges.

The discovery of nitric oxide (NO) as a major signaling molecule in a number of pathophysiological processes - vasodilation, immune response, platelet aggregation, wound repair, and cancer biology - has led to the development of various exogeneous NO delivery systems. However, the development of ideal delivery system for human body application is still left as a challenge due to its high reactivity and short half-life in physiological condition. In this article, an overview of several nano-structures as potential NO delivery system will be presented, along with their recent research results and biomedical applications. Nano-size delivery system has immense advantages compared to others due to its high surface-to-volume ratio and capability for surface modification; thus, it has been proven to be effective in delivering nitric oxide with enhanced performance. Through this novel nano-structure delivery system, we are expecting to achieve sustained release of nitric oxide within adequate range of concentration, which ensures desired drug effects at the target site. Among different nano-structures, in particular, nanoparticle, microemulsion and nanofilm will be reviewed and compared to each other in respect of nitric oxide release profile. The proposed nano-structures for exogeneous NO delivery have a biological significance in that it can be further utilized in diverse biomedical fields as a highly promising therapeutic method.

A microscope is the fundamental research and diagnostic apparatus for clinical investigation of signaling transduction, morphological changes and physiological tracking of cells and intact tissues from patients in the biomedical laboratory science. Proper use, care and maintenance of microscope with comprehensive understanding in mechanism are fully requested for reliable image data and accurate interpretation for diagnosis in the clinical laboratory. The standard operating procedure (SOP) for light microscopes includes performance procedure, brief information of all mechanical parts of microscopes with systematic troubleshooting mechanism depending on the laboratory capacity. Maintenance program encompasses cleaning objective, ocular lenses and inner optics; replacement and calibration of light source; XY sample stage management; point spread function (PSF) measurement for confocal laser scanning microscope (CLSM); quality control (QC) program in fluorescent microscopy; and systematic troubleshooting. Laser safety is one of the concern for medical technologists engaged in CLSM laboratory. Laser safety guideline based on the laser classification and risk level, and advisory lab wear for CLSM users are also expatiated in this overview. Since acquired image data presents a wide range of information at the moment of acquisition, well-maintained microscopes with proper microscopic maintenance program are impulsive for its interpretation and diagnosis in the clinical laboratory.

In Korean society, universities represent institutions of higher education. Industrialization and economic development led to a small number of elite groups at the helm of these institutions. However, our society has encouraged a lifelong system of learning, and apparently, the present university system does not represent an ideal scenario. The Korean government recognized the need for appropriate changes. The events associated with the implementation of related policies occurred at the Ewha Womans University (Seoul) last year. This article is based on the notion of lifelong education to further our understanding of the role of university in the absence of a consensus among university and college members regarding lifelong learning in our society. As an alternative, we looked at the case of France, which is adopting a lifelong education system and implementing related policies ahead of us. Despite regulatory challenges and adaptation of the role of public education in lifelong learning, France has laid a solid foundation. In our case, we are recognizing the need to prepare for lifelong learning. In particular, it is necessary to increase public awareness of education by clearly recognizing our national responsibility and increasing the financial support to universities, accordingly. Above all, the role and attitude of universities must change, along with the perception of its members.

Atopic dermatitis is a chronic, recurrent, inflammatory skin disease that is a well-known allergic disease with severe itching, making daily life difficult. Since the immunomodulatory action of vitamin D has been reported, several researchers have attempted to determine the correlation between vitamin D and atopic dermatitis. In this review, 41 articles meeting the inclusion criteria were selected and reviewed from the articles published to date. Several studies have reported that low vitamin D levels are associated with the onset of atopic dermatitis and severe atopic dermatitis, but the opinions remain conflicting. Similarly, there are conflicting opinions on the improvement effect of oral vitamin D supplementation on atopic dermatitis, but some possibilities have been suggested. To apply vitamin D as a therapeutic agent for atopic dermatitis, a more systematically designed experiment should be conducted, and an appropriate intake dose for an immunomodulatory function should be obtained.

In the remodeling projects, clients without architectural expertise have limitations in presenting requirements accurately. In some cases, designers and contractors may not recognize their demands exactly, and deliver final products that are different from the clients' intentions. 3D modeling visualizing final products in previous has been regarded as a solution to enhance understanding and communication. However, this approach has the limitation that the final results are presented as a virtual outputs. In the remodeling project, an alternative, mixed-reality, is likely to reinforce the reality as it enables to present remain structure and the parts to be built together. This paper examines the mixed reality as a solution to support decision making of clients and practitioners in remodeling projects. The examinations is conducted in high-rise office remodeling projects by means of action-research. Clients and practitioners, overview product models presented in the format of 2D drawings, BIM and mixed reality asked to evaluate the effectiveness of each methods in 12 standards. The results have shown that mixed reality has improved the sense of reality, making it easier to predict results, but recognizing patterns is difficult in some areas such as the floor, and it caused dizziness.

Even in an era where 8-meter class telescopes are common, small telescopes are considered very valuable research facilities since they are available for rapid follow-up or long term monitoring observations. To maximize the usefulness of small telescopes in Korea, we established the SomangNet, a network of 0.4-1.0 m class optical telescopes operated by Korean institutions, in 2020. Here, we give an overview of the project, describing the current participating telescopes, its scientific scope and operation mode, and the prospects for future activities. SomangNet currently includes 10 telescopes that are located in Australia, USA, and Chile as well as in Korea. The operation of many of these telescopes currently relies on operators, and we plan to upgrade them for remote or robotic operation. The latest SomangNet science projects include monitoring and follow-up observational studies of galaxies, supernovae, active galactic nuclei, symbiotic stars, solar system objects, neutrino/gravitational-wave sources, and exoplanets.

The present study explored how ADHD assessment, identification, and diagnosis were conducted in research through an overview of research papers on ADHD in the last 10 years. The collected studies were categorized and analyzed by topics including data collection settings, assessment and identification, coexistence with other disabilities, considerable variables throughout evaluation, and biological basis. They were categorized and analyzed according to the identification methods, the number of assessment(s) and the number of informant(s). The results were as follows: First, the assessment and identifying studies on children with ADHD were excessively biased toward clinical settings. Second, the majority of the previous studies explored more the development or validation of tools for the assessment and identifying of ADHD than the other topics. Finally, a high preference for the use of a multiple assessment method in identifying ADHD was found. However, considering methodological aspects, there was a lack of practical application of multi-step process such as including a personal interview, reviewing school records or direct observing rating criteria. Considering these results, we discussed an urgent need for the diagnosis and identification guidelines of ADHD for teachers to effectively identifying ADHD children at schools. The implications of school-based ADHD assessment and diagnosis research were suggested.
