Objective : To investigate the anti-metastasis and preventing relapses of HangAm-Plus (HAP) on pancreatic cancer patient. Methods : A 49 year old male patient diagnosed with pancreatic cancer (T3N0M0) was admitted to EWCC (East-West Cancer Center) on Jul. 21st 2008. He had operated pylorus preserving pancreatoduodenectomy (PPPD) and came to the anti-metastasis and preventing relapses on pancreatic cancer patient. The patient was treated with HangAm-Plus (HAP) (3,000 mg/day) for the period of 33 months from Jul. 21st, 2008 to Apr. 7th, 2011. Tumor markers (CEA and CA19-9) were used to evaluate the disease progression of the patient. Positron Emission Tomography (PET) and Computed Tomography (CT) were also followed up. Results : HAP treatment was well tolerated by the patient. Patient has shown 33 months of disease free survival until now. Conclusion : This case study supports HAP's potential efficacy in the anti-metastasis and preventing relapses of pancreatic cancer patient.

Herein the flow past a submerged circular cylinder with a free surface is mapped onto a reference plane, in which the free surface is transformed to a straight line and the cylinder to a certain shape. A global mapping function between two planes is sought in a manner that linear free-surface elevation is generated in the physical plane. Hereby the Froude mumber $F_h$, based on the submergence depth h', is assumed to be of order 0(1) and the ratio a'/h'(a'=cylinder radius) of order o(1). Wave thus obtained are slightly different in magnitude and phase from usual linear solution. The resulting free wave starts advanced ahead compared to the classical result and its amount depends on Froude number. Based on the present concept wave forces are calculated. In this type of approach the body boundary condition gives more influence on wave resistance than that by the free surface in the speed range $F_h>1$.

General components, free sugars, and free amino acids about Zostera marina which is much distributing and producing along the coastlines of Korea have been separated and identified through Ion exchange resin and Paper chromatography method. So distrigushed are sugars contained that this was quantitated by Bertrand method. 1) The result of the general component analysis of Zostera marina shows that there are much free sugars. 2) According to Bertrand method sugar containment quantitated from terrestrial stem and subterranean stem on Po-hang and Ko-hung areas is much more in terrestrial stem than subterranean stem. 3) Seven kinds of sugars are used in experiments(Table 2) among there glucose, fructose and sucrose which keep the sweetness are very much contained. 4) Shown in Fig. 3 ten kinds of free amino acids inspected from experimental liquid by Paper chromatography are separated, which are known, and one spot which in unknown is additionally separated, and in which four kinds of essential amino acid to nutrient are contained.

The free vibration of rotating Euler-Bernoulli beams with the thickness and/or width of the cross-section vary linearly along the length is investigated by using the Adomian modified decomposition method (AMDM). Based on the AMDM, the governing differential equation for the rotating tapered beam becomes a recursive algebraic equation. By using the boundary condition equations, the dimensionless natural frequencies and the closed form series solution of the corresponding mode shapes can be easily obtained simultaneously. The computed results for different taper ratios as well as different offset length and rotational speeds are presented in several tables and figures. The accuracy is assured from the convergence and comparison with the previous published results. It is shown that the AMDM provides an accurate and straightforward method of free vibration analysis of rotating tapered beams.

It is well known that Raman spectroscopy is powerful tool in analysis of sp3/sp3 bonding fraction in diamond-like carbon(DLC) films. Raman spectra of DLC film is composed of D-peak centered at 1350cm-1 and G-peak centered at 1530cm-1. The sp3/sp3 fraction is qualitatively acquired by deconvolution method. However, in case of DLC film, it is generally observed that G-peak position shifts toward low wavenumber as th sp3 fraction increases. However, opposite results were frequently observed in ta-C films. ta-C film has much higher residual compressive stress due to its high sp3 fraction compared to the DLC films deposited by CVD method. Effect of residual stress on G-peak position is most recommendable parameter in Raman analysis of ta-C, due to its smallest fitting error among many parameters acquired by peak deconvolution of symmetric spectra. In current study, the effect of residual stress on Raman spectra was quantitatively evaluated by free-hang method. ta-C films of different residual stress were deposited on Si-wafer by modifying DC-bias voltage during deposition. The variation of the G-peak position along the etching depth were observed in the free-hangs of 20~30${\mu}{\textrm}{m}$ etching depth. Mathematical result based on Airy stress function, was compared with experimental results. The more reliable analysis excluding stress-induced shift was possible by elimination of the Raman shift due to residual compressiove stress.

The repetitive vibrating action of an aerodynamic load causes an external fuel tank's horizontal fin to experience a shorter life cycle than its originally predicted one. Store separation analysis is needed to redesign the fin of an external fuel tank. In this research, free-drop tests were conducted using 15% scaled models in a subsonic wind tunnel in order to analyze the store separation characteristics of an external fuel tank. The store separation trajectory based on grid tests was also obtained to verify the results of the free-drop tests. The results acquired from the free-drop tests correlated well with the grid tests in regards to the trajectories and behavior of the stores separated from the aircraft. This agreement was especially noted in the early stages of the store separation.
