Purpose: In this study is necessary to find ways to prevent terrorism among the six major life-cycle safety education-oriented measures. Method: In this study the literature review method and the qualitative research method using a questionnaire were applied, focusing on previous studies related to diplomatic missions in korea. The questionnaire was conducted for about 60 days from May 11 to June 30, 2021. Targeted over 15 years of experience in drones and social safety, the total number of participants is 10. Result: The conclusion drawn mainly by experts on research on safety measures against terrorism centered on safety education of the six major life cycles is as follows. First, most of the opinions on the need for education on safety behavior in terrorist accidents across the country are that threats to safety around the world are increasing and, in particular, aspects of terrorism are diversified. Second, there were many opinions that the need for additional safety education on terrorism safety behavior to the six life-cycle safety education should be reviewed to reflect terrorism safety education in all six life-cycle safety education areas. Third, there were many opinions on the need for terrorist safety experts and professional educational institutions that required the establishment of terrorist safety education instructors and private educational institutions with civilian experience. Conclusion: Most of the research results on measures to prevent terrorism focused on safety education in the six major life cycles were that it is necessary to make it mandatory to use the six major safety education systems for systematic education on terrorism.

The existing evaluation method could not apply the effect of zero span tension generated in the waterproofing layer attached to the surface of the structure at the moment of cracking as the waterproofing layer was constructed in the state where the cracks were formed. The test apparatus developed through this study is expected to be able to conduct tests closer to the environment occurring in actual structures as it is possible to simultaneously create a pressurized (constrained) condition and an environment for zero span tension.

Expression and secretion of CXCL12 are enhanced in autosomal dominant polycystic kidney disease

( Hyunho Kim ),( Jinmo Sung ),( Hyunsuk Kim ),( Hyunjin Ryu ),( Hayne Cho Park ),( Yun Kyu Oh ),( Hyun-seob Lee ),( Kook-hwan Oh ),( Curie Ahn ) 생화학분자생물학회(구 한국생화학분자생물학회) 2019 BMB Reports Vol.52 No.7

Autosomal dominant polycystic kidney disease (ADPKD), one of the most common human monogenic diseases (frequency of 1/1000-1/400), is characterized by numerous fluid-filled renal cysts (RCs). Inactivation of the PKD1 or PKD2 gene by germline and somatic mutations is necessary for cyst formation in ADPKD. To mechanistically understand cyst formation and growth, we isolated RCs from Korean patients with ADPKD and immortalized them with human telomerase reverse transcriptase (hTERT). Three hTERT-immortalized RC cell lines were characterized as proximal epithelial cells with germline and somatic PKD1 mutations. Thus, we first established hTERT-immortalized proximal cyst cells with somatic PKD1 mutations. Through transcriptome sequencing and Gene Ontology (GO) analysis, we found that upregulated genes were related to cell division and that downregulated genes were related to cell differentiation. We wondered whether the upregulated gene for the chemokine CXCL12 is related to the mTOR signaling pathway in cyst growth in ADPKD. CXCL12 mRNA expression and secretion were increased in RC cell lines. We then examined CXCL12 levels in RC fluids from patients with ADPKD and found increased CXCL12 levels. The CXCL12 receptor CXC chemokine receptor 4 (CXCR4) was upregulated, and the mTOR signaling pathway, which is downstream of the CXCL12/CXCR4 axis, was activated in ADPKD kidney tissue. To confirm activation of the mTOR signaling pathway by CXCL12 via CXCR4, we treated the RC cell lines with recombinant CXCL12 and the CXCR4 antagonist AMD3100; CXCL12 induced the mTOR signaling pathway, but the CXCR4 antagonist AMD3100 blocked the mTOR signaling pathway. Taken together, these results suggest that enhanced CXCL12 in RC fluids activates the mTOR signaling pathway via CXCR4 in ADPKD cyst growth. [BMB Reports 2019; 52(7): 463-468]

Enhanced generalized modeling method for compliant mechanisms: Multi-Compliant-Body matrix method

Hyunho Lim,Young-Man Choi 국제구조공학회 2022 Structural Engineering and Mechanics, An Int'l Jou Vol.82 No.4

The multi-rigid-body matrix method (MRBMM) is a generalized modeling method for obtaining the displacements, forces, and dynamic characteristics of a compliant mechanism without performing inner-force analysis. The method discretizes a compliant mechanism of any type into flexure hinges and rigid bodies by implementing a multi-body mass-spring model using coordinate transformations in a matrix form. However, in this method, the deformations of bodies that are assumed to be rigid are inherently omitted. Consequently, it may yield erroneous results in certain mechanisms. In this paper, we present a multicompliant- body matrix-method (MCBMM) that considers a rigid body as a compliant element, while retaining the generalized framework of the MRBMM. In the MCBMM, a rigid body in the MRBMM is segmented into a certain number of body nodes and flexure hinges. The proposed method was verified using two examples: the first (an XY positioning stage) demonstrated that the MCBMM outperforms the MRBMM in estimating the static deformation and dynamic mode. In the second example (a bridge-type displacement amplification mechanism), the MCBMM estimated the displacement amplification ratio more accurately than several previously proposed modeling methods.

Development of Particle Flow-Based Inflatable Robot Body for Shape Rigidity Modulation

Hyunho Kim,Sangjoon Jonathan Kim,Junghoon Park,Handdeut Chang,Namkeun Kim,Yeongjin Kim 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.21 No.10

Disaster robots are needed to perform various tasks through narrow gaps between building debris to be used for rescue. A soft material-based disaster robot can have easy access to the rescue site through the narrow gaps. To ensure the robust control and better performance of the soft robot operation, a joint stiff ness modulation mechanism is required. In this paper, we have proposed a noble stiff ness modulation mechanism that includes shape change and self-assembly by using a particle flow-based inflatable robot body. We analyzed the particle filling completion time by injecting air and particles at a constant pressure into the soft chamber depending on several parameters (the size of the particle, the size of the reservoir, the volume ratio between the chamber volume and the total volume of the particle, and the injected air pressure). Of these, the most dominant factors influencing the completion time were particle size and pressure. It was observed that the smaller the size of the particle, the shorter time. The completion time tended to decrease as the air pressure increased.
