  • This paper investigates the effects of the tensile catenary action on dynamic increase factor (DIF) in the nonlinear static analysis for progressive collapse of steel-frame buildings. Numerical analyses were performed to verify the accuracy of the empirical and analytical expressions proposed in the literature in cases where the catenary action is activated. For this purpose, nonlinear static and dynamic analyses of a series of steel moment frame buildings with a different number of spans and stories were carried out following the alternate path method. Different column removal scenarios were considered as separate load cases. The dynamic increase factor that approximately compensates for the dynamic effects in the nonlinear static analysis was selected so to match results from the nonlinear dynamic analysis. The study results showed that the many expressions in literature may not work in cases where the catenary stage is fully developed.

  • The purpose of this study is to investigate the tendency of the research on the traditional scenery architecture based on the old literature for the last 10 years and to suggest direction of the research on the traditional scenery through utilization of the old literature. For the tendency analysis of the research on the traditional scenery, I investigated and analyzed researches published in the Journal of the Korean Institute of Traditional Landscape Architecture between 2002 and 2012, and reviewed the utilization of the old literature about research on the traditional scenery. The number of the research papers through the old literature was two or three a year by 2009, but has increased to more than eight from 2010. The utilization tendency of the old literature was mostly to use the Korean translations or to use a collection of an individual's works after partially translating. As some of the researches were carried out only through translations even when they used the original, historical evidence on the translation of the original was insufficient. I can suggest the direction of the research on the traditional scenery by the results as follows: it is necessary to present both translation and the original and to specify the source of translation, for the efficient understanding and verification of the original. Professional translation of landscape architecture and scenery also seems to be necessary for the records of the current state. For the analysis of the old literature, as the analysis of the traditional scenery both through poetry and records facilitates assumption of the location of landscape by the abundant data, it seems to be necessary to approach research, using poetry and prose complementarily, after preparing foundation of research based on the records.

  • The purpose of this study is to tell stories about the space of the Museom village as the Museom Byeolli Literature Museum, to recognize the importance of the local literature museum and strengthening the position of the Museom Village. For this, we analyzed the current status of the Museom Village and examined its value and meaning. Based on this theoretical review and the analysis of the subject of the study, we constructedthe Byeolli Literature Museum and made it possible for visitors to feel placeness with the story related to Jihun Joe. For this, the museum consists of a space for lovers, a space for thought, a space for consideration, and a space for healing. The space is telling the story about love, village, dining table, amusement and has maximized the space of the village which is literature contents and the background of literature work. The museum is going to be a complex cultural space where nature, culture, and literature are combined to enhance the image of the region and raise brand value.

  • Oxidative stress, which results in an excessive product of reactive oxygen species (ROS), is one of the fundamental mechanisms of the development of hypertension. In the vascular system, ROS have physical and pathophysiological roles in vascular remodeling and endothelial dysfunction. In this study, ROS-hypertension-related genes were collected by the biological literature-mining tools, such as SciMiner and gene2pubmed, in order to identify the genes that would cause hypertension through ROS. Further, single nucleotide polymorphisms (SNPs) located within these gene regions were examined statistically for their association with hypertension in 6,419 Korean individuals, and pathway enrichment analysis using the associated genes was performed. The 2,945 SNPs of 237 ROS-hypertension genes were analyzed, and 68 genes were significantly associated with hypertension (p < 0.05). The most significant SNP was rs2889611 within MAPK8 (p = $2.70{\times}10^{-5}$; odds ratio, 0.82; confidence interval, 0.75 to 0.90). This study demonstrates that a text mining approach combined with association analysis may be useful to identify the candidate genes that cause hypertension through ROS or oxidative stress.

  • Objectives This study was aimed to evaluate the effects of Chuna manual therapy (CMT) for the treatment of cerebral palsy. Methods The randomized controlled trials (RCTs) on the treatment of CMT for cerebral palsy in children were selected among the literature published until January 2021 in seven databases. The quality of the literature was evaluated using the Cochrane's risk of bias tool, and RevMan 5.3 was used for the synthesis of results. Results Total 801 pediatric patient with cerebral palsy incontinence were finally selected from twelve RCTs. The total effective rate of the combined treatment general rehabilitation and CMT is statistically significantly higher (P<0.0001) than that of general rehabilitation alone. Conclusions This study suggests that general rehabilitation combined with CMT for cerebral palsy in children might be more effective in improving symptoms than general rehabilitation alone. As the number and quality of the literature included in the meta-analysis was insufficient, high-quality clinical studies on CMT for cerebral palsy would be required.

  • In this paper, under some new appropriate conditions imposed on the parameter and mappings involved in the resolvent operator associated with a P-accretive mapping, its Lipschitz continuity is proved and an estimate of its Lipschitz constant is computed. This paper is also concerned with the construction of a new iterative algorithm using the resolvent operator technique and Nadler's technique for solving a new system of generalized multi-valued resolvent equations in a Banach space setting. The convergence analysis of the sequences generated by our proposed iterative algorithm under some appropriate conditions is studied. The final section deals with the investigation and analysis of the notion of H(·, ·)-co-accretive mapping which has been recently introduced and studied in the literature. We verify that under the conditions considered in the literature, every H(·, ·)-co-accretive mapping is actually P-accretive and is not a new one. In the meanwhile, some important comments on H(·, ·)-co-accretive mappings and the results related to them appeared in the literature are pointed out.

  • The 5G is the 5th generation mobile network that provides enhanced mobile broadband, ultra-reliable & low latency communications, and massive machine-type communications. New services can be provided through multi-access edge computing, network function virtualization, and network slicing, which are key technologies in 5G mobile communication. However, these new technologies provide new attack paths and threats. In this paper, we analyzed the overall threats of 5G mobile communication through a literature review. First, defines 5G mobile communication, analyzes its features and technology architecture, and summarizes possible security issues. Addition, it presents security threats from the perspective of user devices, radio access network, multi-access edge computing, and core networks that constitute 5G mobile communication. After that, security requirements for threat factors were derived through literature analysis. The purpose of this study is to conduct a fundamental analysis to examine and assess the overall threat factors associated with 5G mobile communication. Through this, it will be possible to protect the information and assets of individuals and organizations that use 5G mobile communication technology, respond to various threat situations, and increase the overall level of 5G security.
