동적 물체에 대한 로봇 매니퓰레터의 Visual Servoing

오승욱,양원영,심귀보 중앙대학교 생산공학연구소 1995 생산공학연구소 논문집 Vol.4 No.1

This paper presents a new method for visual servoing to control the pose(position and orientation) of the robotic manipulators for grasping the 3-D moving object whose initial pose and motion parameter are unknown by using the stereo camera. The stereo camera is mounted on the end-effector of robotic manipulator. In order to track the current pose of robotic manipulator to the desired pose, we use the Jacobian relating the change in image feature point to the change in the object's pose with respect to the camera. In this paper the simple PD controller is adopted for tracking the desired pose. The effectiveness of the proposed method is confirmed by some computer simulations.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

The rain water samples were collected at Chunchon and Seoul by using wet only automatic sampler from January 1996 through December 1997. The daily base rain water samples collected over than 95% rainy events during the whole period. The samples were measured both pH and conductivity, and were analysed major ionic components, SO₄^(2-), NO₃^(-), Cl^(-), NH₄^(+), Ca^(2+), Na^(+) and K ^(+), by ion chromatography. In 1996, about 77% sampled rain water showed below pH 5.6 and the 60% of rain water was lower than pH 5.0. The volume weighted average pH was 4.7 at all sites. In 1997, the volume weighted average pH was 4.6 and 4.9 at Seoul and Chunchon, respectively. Among the rain water samples, 87% and 55% of samples showed below than pH 5.6 and 5.0, respectively. The pH value of Chunchon was significantly (p<0.05) lower than Seoul at the rain samples for less than 20 ㎜ rainfall. However conductivity of the rain samples were 20.9 μS/㎝ for 1996 and 27.7 μS/㎝ for 1997 at Seoul, and 19.1 μS/㎝ for 1996 and 14.1 μS/㎝ for 1997 at Chunchon. H₂SO₄AND HNO₃CONTRIBUTED 65.9% and 29.6% of free acidity at Seoul, respectively. The ratio of [NO₃^(-)]/[nss-SO₄^(2-)] were 0.43 at Seoul and 0.51 at Chunchon for rain samples for less than 20 ㎜ rainfall.

The Effect of Adding Kami-guibi-tang to Acetylcholinesterase Inhibitor Treatment on the Cognitive Function of Mild Alzheimer's Disease Patients: Study Protocol of a Randomized, Placebo-Controlled, Double-Blind Pilot Trial

Yang, Seung-bo,Kim, Ha-ri,Shin, Hee-yeon,Kim, Jeong-hwa,Lee, Chang-woo,Jahng, Geon-ho,Park, Seong-uk,Ko, Chang-nam,Park, Jung-mi The Society of Internal Korean Medicine 2020 大韓韓方內科學會誌 Vol.41 No.3

Background: Alzheimer's disease (AD) is a chronic neurodegenerative disease that causes disorientation, mood swings, problems with language, and difficulty remembering recent events. Acetylcholinesterase inhibitors (AchEIs) and memantine have been used to slow the course of the disease, but they can neither modify its progression nor prevent disease onset. Previous studies have suggested that Kami-guibi-tang (KGT) could be beneficial for supporting cognitive function in AD patients, but few clinical trials have been published. This pilot study aimed to evaluate the effect of KGT in improving cognitive function in AD patients. Methods: The study will be a randomized, placebo-controlled, double-blind, single-center trial conducted using subjects diagnosed with mild AD by neurologists. Study subjects will be randomly assigned to either a treatment or control group. The treatment group will receive KGT granules for 24 weeks, while the control group will receive placebo granules. AchEI administration will be maintained in both groups during the entirety of the study. Subjects will be assessed using the following exams: the Seoul Neuropsychologic Screening Battery (SNSB) for cognitive function; brain magnetic resonance imaging (MRI) for brain metabolite, neurotransmitter, and cerebral blood flow (CBF) measurements; the Korean version of Quality of Life-Alzheimer's Disease (KQol-AD) for quality of life; the Caregiver-Administered Neuropsychiatric Inventory (CGA-NPI) for neurobehavioral symptoms; blood tests for amyloid and tau proteins and general blood parameters; and electrocardiography (ECG) before and after taking the medication. Discussion: Our findings will provide insight into the feasibility of large-scale trials to consolidate evidence for the efficacy of KGT for dementia treatment.

Cynandione A from Cynanchum wilfordii attenuates the production of inflammatory mediators in LPS-induced BV-2 microglial cells via NF-κB inactivation.

Yang, Seung Bo,Lee, Sang Min,Park, Ji-Hae,Lee, Tae Hoon,Baek, Nam-In,Park, Hi-Joon,Lee, Hyejung,Kim, Jiyoung Pharmaceutical Society of Japan 2014 BIOLOGICAL & PHARMACEUTICAL BULLETIN Vol.37 No.8

<P>Cynanchum wilfordii is one of most widely used medicinal plants in Oriental medicine for the treatment of various conditions. In the present study, we isolated cynandione A (CA) from an extract of Cynanchum wilfordii roots (CWE) and investigated the effects of CA on the expression of inducible nitric oxide synthase (iNOS) and pro-inflammatory cytokines in lipopolysaccharide (LPS)-induced BV-2 microglial cells. CWE and CA significantly decreased LPS-induced nitric oxide production and the expression of iNOS in a concentration-dependent manner, while they (CWE up to 500 ?g/mL and CA up to 80 ?M) did not exhibit cytotoxic activity. Results from reverse transcription-polymerase chain reaction (RT-PCR) analysis and enzyme-linked immunosorbent assay (ELISA) showed that CA significantly attenuated the expression of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and IL-1β in LPS-stimulated BV-2 cells. Furthermore, CA inhibited the phosphorylation of inhibitor kappa B-alpha (IκB-α) and translocation of nuclear factor-kappa B (NF-κB) to the BV-2 cell nucleus, indicating that CWE and CA may have effective anti-inflammatory activities via NF-κB inactivation in stimulated microglial cells.</P>

Recent advances in hybrids of carbon nanotube network films and nanomaterials for their potential applications as transparent conducting films

Yang, Seung Bo,Kong, Byung-Seon,Jung, Dae-Hwan,Baek, Youn-Kyoung,Han, Chang-Soo,Oh, Sang-Keun,Jung, Hee-Tae Royal Society of Chemistry 2011 Nanoscale Vol.3 No.4

<P>The use of carbon nanotubes (CNTs) as transparent conducting films is one of the most promising aspects of CNT-based applications due to their high electrical conductivity, transparency, and flexibility. However, despite many efforts in this field, the conductivity of carbon nanotube network films at high transmittance is still not sufficient to replace the present electrodes, indium tin oxide (ITO), due to the contact resistances and semi-conducting nanotubes of the nanotube network films. Many studies have attempted to overcome such problems by the chemical doping and hybridization of conducting guest components by various methods, including acid treatment, deposition of metal nanoparticles, and the creation of a composite of conducting polymers. This review focuses on recent advances in surface-modified carbon nanotube networks for transparent conducting film applications. Fabrication methods will be described, and the stability of carbon nanotube network films prepared by various methods will be demonstrated.</P> <P>Graphic Abstract</P><P>This review focuses on recent advances in surface-modified carbon nanotube networks for transparent conducting film applications. <IMG SRC='http://pubs.rsc.org/services/images/RSCpubs.ePlatform.Service.FreeContent.ImageService.svc/ImageService/image/GA?id=c0nr00855a'> </P>
