  • This study was carried out to standardize the recipe of Gaeseong-Juak. The formation and quality of the Juak were investigated under different treatment conditions. 1. The high ratio of medium flour(20%) in the flour mixture resulted in poor swelling. 2. The flour mixture with 10% strong flour showed higher volume of Gaeseong-Juak compared with the 10% mixture of medium flour, but the score of sensory evaluation was low. 3. The addition of Makkoli in the dough did not give significant difference in the formation of Juak, but the sensory score was low. 4. The deep-frying temperature in the range of 150$\^{C}$ to 170$\^{C}$ allowed the greatest swelling of Gaeseong-Juak, but the highest quality score was obtained at 160$\^{C}$ treatment. Overall, the best preparation condition of Gaeseong-Juak was that the mixture of waxy rice flour with 10% medium flour was kneaded with Makkoli and fried at 160$\^{C}$.

  • A interpenetrating polymer network (IPN) hydrogel, composed of chitosan (CS) and poly(diallydimethylammonium chloride) (PDADMAC) was prepared, which exhibited electrical sensitive behavior. The swelling behavior of the CS/PDADMAC SIPN hydrogel was studied by immersion of the gel into various pH buffer solutions, and their stimuli response in electric fields also investigated. In order to clarify the relationship between the equilibrium swelling ratio and bending behavior of the SIPN hydrogels, the state of water in the SIPN hydrogel was also investigated using differential scanning calorimetry (DSC).

  • Elephantiasis, which is the final stage of lymphedema, has swelling, papillomas and discharges in the skin. Although this disease is recorded in literature since 50 AD, the treatment is not yet. After all this time, complex lymphedema therapy (CLT) involving lymphatic massaging, bandaging, exercise, and skin care is becoming recognized as the best approach to care for people who develop lymphedema. The patient was a 30-year-old male who complained of swelling, papillomas, and discharges on left leg. He was received with CLT for 2 months, and the symptoms of him were improved.

  • We employed in-situ spectroscopic ellipsometry(SE) and imaging ellipsometry(IE) to study the interaction of water and photoresist(PR) in 193 immersion lithography. Real time measurement of SE showed thickness increase when PR was immerged in water indicating swelling effect. From the temporal evolution we could observe its reaction-limited behavior. Meanwhile, IE could identify the modification of PR surface by contact of water even for a short period of a second.

  • In order to investigate the effect of riboflavin on cholesterol and MLHP (methyl linoleate hydroperoxide) -induced fatty liver electron microscopically, riboflavin was given to rate receiving high cholestero and MLHP diet for 4 weeks, 8 week old male Sprague-Dawley rats were administrated diets daily, as following group ; usual diet (control ), riboflavin 910 ug/20gm BW), cholesterol (50mg/gm BW), MLHP(0.1ml/20gm BW), cholesterol plus MLHP, cholesterol plus riboflavin, cholesterol plus MLHP plus riboflavin, by means of intubation into the stomach for 4 weeks. Each group consisted of 10 rats, The liver of the animals were examined ultrstructurally by transmission electronmicroscope. The results wee as follows ; 1) The three group including cholesterol, MLHP, cholesterol plus MLHP feeding resulted in fatty liver. 2) The main finding of the fatty liver were swelling and vacuolation of mitochondria, a lot of lipid droplets, disarrangements and loss of rough endoplamic reticulums. 3) the most striking features in the group of cholesterol plus riboflavin, cholesterol plus MLHP plus riboflavin feeding were decrease of size and number of lipid droplets, mitochondrial swelling and vesiculation, with restortion of rough endoplasmic retriculums. It is postulated with above findings that riboflavin was effective in prevention of cholesterol and MLHP -induced fatty liver.

  • PP hollow fiber membrane was hydrophilized by EVOH dip coating followed by low temperature plasma treatment and UV irradiation. EVOH coating attained high water flux without any prewetting but its stability did not guaranteed at high water permeation rate. At high water permeation rate, water flux declined gradually due to swelling and delamination of the EVOH coating layer causing pore blocking effect. However, plasma treatment reduces the swelling, which suppress delamination of the EVOH coating layer from PP support result in relieving the flux decline. Also, UV irradiation helped the crosslinking of the EVOH coating layer to enhance the performance at low water permeation rate. FT-IR and ESCA analyses reveal that EVOH dip coating performed homogeneously through not only membrane surface but also matrix. Thermogram of EVOH film modified plasma treatment and W irradiation show that crosslinking density of EVOH layer increased. Chemical modification by plasma treatment and UV irradiation stabilized the hydrophilic coating layer to increase the critical flux of the submerged membrane.

  • In hot pressed wood of Pseudotsuga menziesii compressed to 0 - 50 percent at temperature 60 - $180^{\circ}C$, relative humidity conditions affecting dynamic Young's modulus of elasticity and internal friction were investigated. The results obtained are summarized as follows: Moisture absorption of the hot pressed wood decreased with increasing press temperature, but there was no effect on the amount of compression. Thickness swelling dereased with increasing press temperature, and increased with increasing amount of compression. In general, dynamic Young's modulus of elasticity showed a straight line with increasing specific gravity of specimens. Dynamic Young's modulus of elasticity decreased with increasing moisture content, but internal friction increased with increasing amount of moisture content. Dynamic Young's modulus of R specimens pressed in the radial direction showed hight values than T specimens pressed in the tangential direction.

  • By heat treating coal tar pitch between 450∼500$^{\circ}C$, mesophase pitch could be obtained. Subsequently, this pitch was oxi-stabilized between 160∼240$^{\circ}C$ in air for the purpose of reducing swelling and distortion. The mechanism of stabilization was analysed using the thermo-gravity and FT-IR. To investigate the effect of oxi-stabilization, the shore hardness and bending stress were measured with carbonized green body which was made from oxi-stabilized coal tar pitch.

  • Adequate design of engineered barriers, including canister, buffer and backfill, is important for the safe disposal of high-level radioactive waste. Three-dimensional computer simulations were carried out under different condition to examine the thermal and mechanical behavior of engineered barriers and rock mass. The research looked at five areas of importance, the effect of the swelling pressure, water content of buffer, density of compacted bentonite, emplacement type and the selection of failure criteria. The results highlighted the need to consider tensile stress in the outer shell of a canister due to thermal expansion of the canister and the swelling pressure from the buffer for a more reliable design of an underground repository system. In addition, an adequate failure criterion should be used for the buffer and backfill.

  • The removal of trace chlorinated and aromatic hydrocarbons from water by a pervaporation technique has been carried out through poly (dimethylsiloxane) membrane which had been fabricated by the addition crosslinking reaction. This study dealt with the swelling and permeation behaviors of the PDMS membranes with dichloroethane trichloroethane and toluene aqueous solutions. The swelling ratio in the toluene aqueous solution was much higher than those in the chloroethane solutions at all of the operating temperatures and concentrations. The solubility parameter theory was introduced to interpret the affinity between permeates and a membrane material and in all cases this approach seemed to be proper. It was suggested that the existence of water clusters in the membrane due to the hydrophobic characteristics of the membrane made the size of the permeating water larger resulting in suppressing water permeation and increasing enrichment of the organic components. The permeation behaviors at different membrane thicknesses were indirectly interpreted in terms of the effect of concentration polarization.
