Objective: In 1960`s Bonghan Kim`s team found BongHan(BH) ducts which were presumed as acupuncture meridians and BH corpuscles. They asserted Bonghan theory and SanAl theory which was involved in cell division and cell restoration. However, many other experiments which had been operated to demonstrate and find the existence of BH ducts had failed because of the secret of blue stain drugs. During the last several years, BongHan theory has been revived through experimental researches to find the anatomical structures of BH ducts and corpuscles by Soh`s Biomedical Physics Lab. Soh`s research team used the staining with Janus Green B, Alcian blue, nanoparticles and Acridine Orange. We used DAPI staining to find the existence of BH ducts and the corpuscles and to observe nuclear arrangement. Methods: We used japan white rabbits as experimental animals. BH ducts and corpuscles were stained with DAPI. The nucleus configuration in BH ducts stained with DAPI were observed with microscope. Results: In this study, we found thread like structures in silver white color distinguished from the blood vessels, nerves and lymph vessels. These thread like vessels in the linear duct shape were connected to same colored mass in the ball shape. Thread like structures we found could be separated easily from the surrounding other organ mass. The nuclei of the thread like structure in DAPI staining, are about 10~20㎛ length, in rod shape and linear arrangement. Conclusion: We concluded that the thread like structure we found was same vessel reported by Soh`s research team, BongHan ducts and corpuscle.

New approaches for micro-controlling of oxygen dopant contents in silicon-based thin films with application to multi-band gap solar cells

So, H.,Jang, J.,Lee, D.,Hong, M. Elsevier 2012 Current Applied Physics Vol.12 No.suppl4

Using the neutral-beam-assisted chemical vapor deposition (NBaCVD) system [5-12], an alternative technique that can control the oxygen doping in a silicon-based thin film has been developed. This brand-new technique has the ability to controlling of optical band gaps by micro-control the oxygen dopant concentrates in the nc-Si thin films. This control of the oxygen doping results in self-biasing on the internal antenna of an inductively coupled plasma (ICP) source; it also results in the hydrogen neutral beam (NB) energy being adjusted by the reflector bias. The oxygen atoms are supplied from the sputtering of an internal ICP antenna covered by a quartz tube and are eliminated by the energetic hydrogen NB in the NBaCVD system, rather than by a mass-flow-controller (MFC) used in conventional CVD. These results are observed via Fourier Transform Infrared Spectroscopy, X-ray Photoelectron Spectroscopy, Secondary Ion Mass Spectroscopy and UV-visible data. The result of this experiment allows the fabrication of multi-junction solar cells with gradually varying optical band gaps.

SIZE OPTIMIATION OF AN ENGINE ROOM MEMBER FOR CRASHWORTHINESS USING RESPONSE SURFACE METHOD

S. OH,B.-W. YE,H.-C. SIN 한국자동차공학회 2007 International journal of automotive technology Vol.8 No.1

The frontal crash optimization of an engine room member using the response surface method was studied. The engine room member is composed of the front side member and the sub-frame. The thicknesses of the panels on the front side member and the sub-frame were selected as the design variables. The purpose of the optimization was to reduce the weight of the structure, under the constraint that the objective quantity of crash energy is absorbed. The response surface method was used to approximate the crash behavior in mathematical form for optimization procedure. To research the effect of the regression method, two different methodologies were used in constructing the response surface model, the least square method and the moving least square method. The optimum with the two methods was verified by the simulation result. The precision of the surrogate model affected the optimal design. The moving least square method showed better approximation than the least square method. In addition to the deterministic optimization, the reliabilitybased design optimization using the response surface method was executed to examine the effect of uncertainties in design variables. The requirement for reliability made the optimal structure be heavier than the result of the deterministic optimization. Compared with the deterministic optimum, the optimal design using the reliability-based design optimization showed higher crash energy absorption and little probability of failure in achieving the objective.

Fast motion estimation using modified diamond search patterns

So, H.,Kim, J.,Cho, W.-K.,Kim, Y.-S. IEE 2005 Electronics letters Vol.41 No.2

A fast block motion estimation algorithm is proposed using modified diamond search patterns. This algorithm utilises the directions and magnitudes of motion vectors between interblocks and uses a smaller number of search points than conventional diamond search patterns. Simulation results show that the proposed method significantly improves computational speed over other fast motion estimation algorithms without degradation of distortion.

For trying to frontal attack of new solution by fusion of technical tasks and conditions with it's solving methods of the essential tasks of marine resource development and environmental conservation in addition with elements of electronic high-technologies, the magnetic oil spill adsorbent of Mag-Sorbent* has been prepared and proposed to dispose oil spill from the marine disaster for preventing oil pollution by using them and their system with sequentially circular collection of oil spill mag-sorbent powder and fabrics on the electronic equipment like as barge robot for the scheme of sustainable development of environment-friendly technology. Because of recent marine accident occurred at Tae-An cost and earthquake in Sichuan province were very large scale accident of disaster to prevent and manage of them. So, it was verified from the experiment of electronic demonstrator that the skimmer system of oil spill mag-sorbent powder and fabrics prepared was very effective and useful technique to collect oil spill samples on the water surface specially at the closed space of underground cave. At this point, the barge-based electronic remote control was very useful system operating easily on the marine fields but also water level at the small pool to skim it with the environment-friendly system of the disposing marine disaster and preventing oil pollution using magnetic adsorbents of Mag-Sorbent*.
