This paper dealt with the synthesis and characterization of the polymeric product by the reaction of the water-soluble poly(vinyl alcohol)[PVA] nonwoven fabrics and the phosphoryl chloride ($POCl_3$), which has been applied to prepare water-proofing materials or intermediates for increasing water-proofing or fire-proofing ability of commercially available water-soluble PVA support layer. $POCl_3$ was reacted with PVA nonwoven fabrics under non-aqueous condition, and their reactivity, and chemical structure were checked and discussed. PVA was reacted with $POCl_3$ under the reaction condition of 1:1, or 1:2 mole ratios at 70, 80 and $90^{\circ}C$, and the reaction products were further hydrolyzed. The structure of the resulting products from water soluble PVA nonwoven fabrics reacted with $POCl_3$ were identified by FT-IR or X-ray fluorescence spectrophotometer, and they indicated the PVA polymer chains to have phosphorous and chlorine moieties.

Chitosan is an environment-friendly and natural cationic polymer that can be used as a hair cosmetic additive. Healthy hair and damaged hair samples were experimented on according to treatment conditions using a water-soluble chitosan. Chitosan treated hair samples were studied on the physical and mechanical property changes. It is most effective when the water-soluble chitosan treatment was adjusted to the Neutral (pH6.8) or Acid (pH4.5). When the water soluble chitosan was treated at pH4.5, the tensile strength, tensile elongation, and elasticity of decolorized hair all increased. The virgin and damaged hair both changed into elastic and soft hair. The effect of chitosan treatment is more noticeable in the healthy hair than in the damaged hair.

The influences of sodium chloride, polyethylene glycol 4000 and 20000 on 5-fluorouracil release from disk type silicone polymer devices were examined in isotonic phosphate buffer. These water soluble cosolvent and sodium chloride caused devices to swell in aqueous media. Sodium chloride exerted the greatest influence on drug release. The addition of water soluble cosolvent or sodium chloride to silicone polymeric devices permitted controlled release of 5-fluorouracil, presumably due to the change of the physical microstructure of silicone network, and the solubility and diffusivity of 5-fluorouracil. It seemed that the water soluble drug was released through the hydrophilic pores or pathways formed in the device by the incorporation of a water soluble cosolvent or sodium chloride.

Since a lot of fugitive dust is generated at construction and civil engineering construction sites in Korea, the fine dust regulation at construction sites has been strengthened in accordance with the implementation of the Special Act on Fine Dust Reduction. In a construction site, water is generally sprayed to temporarily reduce the generation rate of scattered dust, but there is a problem that when water evaporates, it scatters again. In this study, the performance of a scattering dust inhibitor incorporating a polymer that stabilizes the ground and reduces the rate of scattering dust by forming a polymer film even when water evaporates using a polymer and a surfactant was evaluated.

Purpose. To prepare polymer based physical mixtures or solid dispersions containing solubilizing compositions using a spray-dryer. Methods. Lovastatin.simvastatin.aceclofenac and cisapride were selected as poorly water-soluble drugs. Dextrin. poly(vinylalcohol). poly(vinylpyrrolidone)and polyethylene glycol were chosen as solubilizing carriers for solid dispersions. The solid dispersions containing solubilizing compositions without drug were prepared without using organic solvents or tedious changes of formulation compositions. (omitted)

The influence of polyethylene glycol derivatives on heparin release from cylindrical monolithic type silicone segment devices was examined in physical saline solution. This water-soluble carrier caused the devices to absorb the water in aqueous media. The release rate of heparin from the devices was increased as molecular weight of polyethylene glycol was increased. Water soluble carrier incorporated into silitone segment devices permits controlled release of heparin that otherwise would be released extremly slowly from the polymer. Heparin released from the silicone segment containing polyethylene glycol showed the first-order kinetics. Without changing the release-pattern, the release rate of heparin could be controlled by varing molecular weight of polyethylene glycol, the water-soluble carrier and depleting polyethylene glycol on the outlayer of devices. The mechanism of release probably showed the creation of pore or microdomine through the devices secondary to the swelling.

유전자 치료에 있어서 안전성의 장점을 지니고 있는 비바이러스성 전달체에 대한 관심도가 높아져가고 있다. 비바이러스성 전달체 중, 양이온성 리포좀이나 합성 유전자 전달체는 in vitro계에서 효율적인 DNA 전달체이지만, 낮은 생체적합성으로 인하여 in vivo 계에서의 응용성은 크게 뒤떨어지고 있다. 한편, 천연 양이온성 다당류인 키토산은 낮은 독성과 강한 양전하를 띠고 있어 유전자 전달 시스템 (gene delivery system)에 있어 아주 기대되는 전달체이다. 본 연구에서는 저분자량 수용성 키토산 (low molecular water-soluble chitosan ; LMWSC)을 이용하여 동맥 벽 세포를 표적할 수 있는 표적성 유전자 전달체를 합성하였다. 상대 점도와 Kina 적정법을 이용하여 LMWSC의 점도 평균 분자량 $(M_W)$과 탈아세틸화도 (degree of de acetylation ; DDA)를 측정하였고 구조는 FTIR, $^1H-NMR$, 그리고 $^{13}C-NMR$을 통하여 분석하였다. 동맥 벽을 표적하기 위한 유전자 전달체로서 pegylated LMWSC 의 말단에 특이성 세포 표적 펩타이드인 artery wall binding peptide (AWBP)를 결합시킴으로써 AWBP-PEG-g-LMWSC을 합성하였고 FTIR, $^1H-NMR$. zeta potentiometer. 그리고 atomic force microscopy (AFM)을 이용하여 분석하였다.
