The purpose of this study was to investigate the applicability of the polymer blends obtained from the commingled waste plastics and waste paper. To enhance the mechanical properties of the blends compatibilizers were employed. Compatibilizers were composed of rosin and silicon. Tests revealed that the compatibilizers effectively and synergistically works on the mechanical properties, especially enhance the tensile strength and impact strength simultaneously. Fracture behavior which was attributed to the strength enhancement was one of the fragile fracture rather than the brittle fracture.

In this study for enhancing the durability of permeable pavement material polyurethane(PU) adhesives were developed, and the physical properties upon polymerization and water were studied. PU were polymerized into two types; an air-crosslinking type and a chemically crosslinking type. The property changes upon different adhesives and water were evaluated with the compressive strength which is the principal measurement of the property of pavement materials. Results tells that as the 1st adhesive epoxy was appropriate, and as the 2nd adhesive the chemically crosslinking PU is recommended.

This paper describes the polymer concrete recently propagating in the field of civil and architecture. Generally, polymer concrete has advantages of better mechanical properties such as high compressive strength and high tenacity, and of better durability against moisture and chemicals over existing cement concrete. This paper, also, manifests, "E'Concrete", a newly invented polymer concrete. This rubber made from waste-tires showed excellent compressive strength. Preparation of the rubber concrete had a desirable side effect that through the production of this article environmental pollution problem of waste-tires should be diminished away.

Consideration of clean environment and lucrative new article bestowed a recycling process of waste plastic and waste concrete together into the plastic concrete. Comparing compressive strength of each composition of plastic concrete information about compatability of plastics and reenforcement of peroxide and aggregate could be gained. Results revealed that compatability between or among PE , PP, PS, PVC and ABS was not seen, but peroxide and aggregate together had synergistic effect on the strength of plastic concrete.

Cellulose acetate dissolved in a combination of trifluoroacetic acid and methylene chloride solution is liquid crystalline above a certain concentration. The main objectives of the work reported here were; 1) to show the mesophase formation of CDA that occurs in solution state. 40% CDA solutions in TFA/CH2C12(6/4,v/v) were liquid crystalline and showed low enough viscosity for spinning. 2) to develop regenerated cellulosic fibers from the mesomorphic state. Solutions which were mesomorphic were spun into a methanol bath and relatively strong cellulosic filaments were successfully produced using air-gap spinning equipment. Analysis showed that the semirigid CDA polymer chains in liquid crystalline solution straighten away from the others and this high orientation renders relatively high strength to CDA fibers.

The purpose of this study was to see whether the waste plastics would be a substitute for wood. Commingled waste plastics(PVC and PET excluded) were mixed with waste cellulose(waste cotton), then these mixtures, without any compatibilizer, were transformed to twin-screw extruder, and plate-like extrudates were obtained. The extrudates showed tensile strength of 31.27MPa, tensile strain 11.30%, modulus 1691MPa, toughness 585N-mm, density 0.84g/㎤, and compressive strength 15.98MPa at the mixture of 90/10(plastic/cotton). These value are very comparable to those of wood.

사회공포의 구조모형 분석 : 행동억제, 신체상, 자기효능감을 중심으로
홍영근 대구대학교 특수교육재활과학연구소 2011 특수교육재활과학연구 Vol.50 No.3
본 연구의 목적은 사회공포를 발생 및 유지시키는 변수인 행동억제, 신체상, 자기효능감과 사회공포와의 관계를 알아보기 위한 것이다. 이 관계를 알아보기 위하여 176명의 대학생들을 대상으로 질문지 검사를 실시하여 사회공포, 행동억제, 신체상, 자기효능감 간의 관계구조 모형을 검증하였다. 그 결과 행동억제와 신체상이 자기효능감을 매개로 사회공포를 일으키는 모형이 값, TLI, SRMR, CFI, RMSEA에서 적합한 것으로 나타났다. 본 연구를 통해 행동억제와 자신의 신체상에 대한 평가가 사회공포에 직접적 영향을 미친다기 보다는 자기효능감을 매개하여 사회공포에 영향을 미친다는 것을 알 수 있었고, 연구 결과를 통해 기존의 사회공포의 인지모형인 Rapee와 Heimberg의 사회공포의 인지모형과 Clark과 Wells의 사회공포의 인지모형 등에 대한 개선점을 제안하였고, 치료 장면에서의 시사점을 제시하였 다. The purpose of this study was to investigate a structural relationship among the relate variables of social phobia. 176participants completed questionnaires assessing behavioral inhibition, body image, self-efficacy, social phobia The sample variance-covariance matrix was analysed using Amos 18.0 and a maximum likelibood mimimizatin function. Goodness of fit was evaluated using the TLI, SRMR, RMSEA and its 90% confidence interval. The results was as follows: First the direct effect of behavioral inhibition and body image on self-efficacy was significant. Second, the direct effect of self-efficacy on social phobia was significant. Finally, the significant indirect effect of behavioral inhibition and body image was mediated by self-efficacy.
