The advanced technologies of the 4th industry are demanding a lot of changes in the manufacturing process and facility maintenance work site very quickly in various industrial sites in Korea. This study introduces the current status analysis and technology derivation research process for big data extraction, which is essential to apply the important smart factory technology of the 4th industry to the production manufacturing process and facilities in Korea. In particular, if facility automation for a smart factory has to be done in an extreme work environment where there are two or more different types of work or production equipment, very difficult elements exist. In this study, big data necessary to prevent failure of the current collector in charge of supplying large-capacity electricity in large crane facilities in the steel production and steelmaking process with a lot of dust and high heat sources and apply the technology to automatically maintain and manage problems The purpose of this study is to implement the extraction method and research contents together with pictures to enable field application.

The experimental study from the beam-column subassemblies is presented. Test parameters are flexual strength ratio, joint shear stress factor and transverse steel reinforcement ratio. The results from cyclic loading tests show very ductile characteristics. In the designing of ductile moment resisting frame, therefore, transverse reinforcing effect of column and joint should be included.

To investigate the pharmacokinetic difference between the two amoxicillin (AMX) particles in rabbits after intramuscular injection (i.m.), both of AMX-S (particle size: 10 ㎍) and AMX-L (particle size: 100 ㎍) were injected into New Zealand White rabbits (1.2±0.3 ㎏) at a dose rate of 10 ㎎/㎏ of body weight. In this study, serum AMX concentrations were detected by microbiological assay with E. coli BE 1186 which shows high antibiotic sensitivity. After i.m. administration, AMX-S and AMX-L were best fitted as 1-compartment model with the absorption and elimination phase. The biological half-life (T_1/2, _k10) of AMX-S is 4.06±1.09 h and that of AMX-L 4.76±0.69 h. The serum maximal concentration time (T_max) of AMX-S and AMX-L were 0.88±0.17 h and 0.77±0.11 h, respectively. Maximal AMX concentration (C_max) (AMX-S: 5.71±0.62 ㎍/㎖, AMX-L: 5.04±0.25 ㎍/㎖) in serum showed a significant difference (p<0.05). In terms of bioequivalance, however, there was no difference between the two AMX's after i.m. injection in the basis of C_max and AUC.

반유통형의 초임계유체 염색장치를 사용하여 333.2K, 373.2K, 413.2K의 일정온도와 150bar-300bar의 압력에서 이산화탄소에 분산염료를 용해하여 폴리에스터 직물을 염색하고 염색시간에 따른 염착량을 측정하였다. 같은 방법으로 HFC-134a를 사용하여 383.2K와 413.2K의 일정온도와 50bar-160bar의 압력에서 염료를 용해하여 염색을 실시하고 염색시간에 대한 염착량을 측정하였다. 염착랑에 대한 초임계유체의 온도와 압력의 영향이 검토되었다. 이산화탄소와 HFC-134a의 초임계 용매를 비교하기 위하여 두 용매에 대한 염료의 용해도와 평형염착량의 관계를 검토하였다. 동일한 온도에서 HFC-134a를 초임계유체로 사용할 때보다 이산화탄소를 사용하는 것이 큰 평형염착량을 나타내었다. HFC-134a에 대한 염료의 용해도는 이산화탄소보다 훨씬 크지만 직물을 염색하는 초임계용매는 이산화탄소가 더 유리하였다. The uptake of disperse dye into polyester fiber in supercritical carbon dioxide was measured in the pressure range between 150 bar and 300 bar at each temperature of 333.3K, 373.2K and 413.2K, and the uptake in supercritical HFC-134a was measured in the pressure range between 50 bar and 160 bar at each temperature of 383.2K, 413.2K, using a flow-type apparatus with a cylindrical dyeing vessel. The effect of dye uptake in supercritical fluids on temperature and pressure was investigated. The dye uptake at constant pressure was much increased with temperature than it did with the pressure at constant temperature. The equilibrium uptakes of disperse dye in supercritical carbon dioxide were compared with those in the supercritical HFC-134a. The equilibrium uptakes in the supercritical carbon dioxide were much great than those in the HFC-134a at the same temperature. The supercritical carbon dioxide is better supercritical media than the HFC-134a, even though dye in the supercritical HFC-134a is much solved than in the supercritical carbon dioxide.
Control of Robot Manipulators Using Time-Delay Estimation and Fuzzy Logic Systems
Bae, Hyo-Jeong,Jin, Maolin,Suh, Jinho,Lee, Jun Young,Chang, Pyung-Hun,Ahn, Doo-sung The Korean Institute of Electrical Engineers 2017 Journal of Electrical Engineering & Technology Vol.12 No.3
A highly accurate model-free controller is proposed for trajectory tracking control of robot manipulators. The proposed controller incorporates time-delay estimation (TDE) to estimate and cancel continuous nonlinearities of robot dynamics, and exploits fuzzy logic systems to suppress the effect of the TDE error, which is due to discontinuous nonlinearities such as friction. To this end, integral sliding mode is defined using desired error dynamics, and a Mamdani-type fuzzy inference system is constructed. As a result, the proposed controller achieves the desired error dynamics well. Implementation of the proposed controller is easy because the design of the controller is intuitive and straightforward, and calculations of the complex robot dynamics are not required. The tracking performance of the proposed controller is verified experimentally using a 3-degree of freedom PUMA-type robot manipulator.
Polymorphisms in Apoptosis-Related Genes and <i>TP53</i> Mutations in Non-Small Cell Lung Cancer
Bae, Eun Young,Lee, Eun Jin,Kang, Hyo-Gyoung,Lee, Shin Yup,Jin, Gwang,Lee, Won Kee,Choi, Jin Eun,Jeon, Hyo-Sung,Lim, Jeong Ok,Lee, Eung Bae,Park, Jae Yong The Korean Academy of Medical Sciences 2011 JOURNAL OF KOREAN MEDICAL SCIENCE Vol.26 No.11
<P>Apoptosis plays an essential role in the elimination of mutated or transformed cells from the body. Therefore, polymorphisms of apoptosis-related genes may lead to an alteration in apoptotic capacity, thereby affecting the occurrence of <I>TP53</I> mutations in lung cancer. We investigated the relationship between potentially functional polymorphisms of apoptosis-related genes and <I>TP53</I> mutations in non-small cell lung cancer (NSCLC). Twenty-seven single nucleotide polymorphisms in 20 apoptosis-related genes were genotyped by a sequenome mass spectrometry-based genotyping assay in 173 NSCLCs and the associations with <I>TP53</I> mutations in the entire coding exons (exons 2-11), including splicing sites of the gene, were analyzed. None of the 27 polymorphisms was significantly associated with the occurrence of <I>TP53</I> mutations. This suggests that apoptosis-related genes may not play an important role in the occurrence of <I>TP53</I> mutations in lung cancer.</P>
