WAP(Wireless Application Protocol)을 기반으로 한 무선 인터넷 분야의 발전과 더불어 엄청나게 늘어난 무선 인터넷 이용자들의 컨텐츠에 대한 요구가 다양해지고 있다. 따라서 CP(Content Provider)들은 무선 장비에 맞게 설계된 WML(Wireless Markup Language)과 WMLScipt를 무선 장비를 사용하지 않고, 실제와 비슷한 상황에서 컨텐츠(Content)를 개발할 수 있는 환경이 필요하게 되었다. 본 논문에서는 무선 웹 컨텐츠를 좀 더 쉽게 개발할 수 있도록 도와주는 WML 마이크로 브라우저의 구현에 대해 기술한다. WML 마이크로 브라우저는 WML 파싱(parsing) 모듈과 브라우징(Browsing)모들로 구성되고. 클라이언트 측 WAP 스택으로 요청한 결과로 얻은 컨텐츠를 화면에 출력한다.

많은 웹 브라우저들이 사용되고 있고 또 개발 중에 있다. W3C등의 인터넷 사이트에서는 Libwww를 비롯한 각종 패키지들의 소스를 공개하고 있어서 웹 브라우저를 포함한 인터넷 어플리케이션의 개발에 많은 도움이 되고 있다. 본 논문의 목적은 내장형(Embedded) 실시간 운영체제에서도 동작할 수 있는 단순화되고 가벼운 형태의 웹 브라우저를 설계하고 구현하는 것이다. 브라우저의 단순화를 위해 일단 웹 페이지의 텍스트만을 처리하는 브라우저를 설계하고 구현하였다. 브라우저 개발도구로서 Libwww를 사용하였다.

The purpose of this research was to find out the effects of the person and costume on the formation of first impression. 4 Models were choosen who had sporty, intellectual, social and cute impression. Tried on them sporty, intellectual, social and cute costumes, 16 pictures of them were taken four ty four method, and those were shown to 640 college girl students in Seoul to check the change of impression. The results are as follows : 1) The sporty costume to he perceived as sporty than either the social or intellectual and cute costume. 2) The social person to he perceived as social than either the sporty on intellectual and cute person. 3) The intellectual costume to be perceived as intellectual than either the sporty or social & cute costume. 4) The cute costume to be perceived as cute than either the sporty or social and intellectual costume.

In the present study, warpage characteristics of mobile phone cover through injection molding process were investigated by using design of experiments. Warpage in plastic injection molding process has a significant effect on quality of product. Effects of injection time, packing pressure, packing time, mold temperature ana melt temperature on warpage of mobile phone cover were considered by CAE analysis and experiment with Taguchi method. The degree of warpage for the injection molded product was measured by using three dimensional CMM. It was shown that temperature parameter has more significant effect on the warpage of mobile phone cover than pressure parameter.

This research is about SDM (Structural Dynamics Modification) technique using embosses. SDM using embosses do not need to add additional mass element ana model of embosses and resulting huge calculation for getting analytical solution of an embossed structure. The object of this research is to suggest a method to guide placing embossment in a structure to raise its natural frequencies. Two methods to optimize model with embossing are suggested, indepuldently. The former is response surface analysis by neural network. And the latter is an indirect method using modal dynamic strain energy.

The effect of topical application 100,300 and 500 $\mu$g/ ml with Mineral Salts of magnesium sulphate and potassium nitrate on economic parameters was ana- lyzed following treatment of last larval stadium. The treated larvae showed significantly decreased larval weight and silk gland weight in all the treated groups along with other decreased Iarval, cocoon and adult parameters. The female cocoon weight was significantly decreased in all the treated groups with decreased female cocoon shell weight and male cocoon weight at 300 and 500$\mu$g/ml respectively. The length and weight of filament was significantly decreased at 300 and 500 $\mu$g/ml respectively and denier at 500 $\mu$g/ ml. The fecundity decreased significantly in 300 and 500 $\mu$g/ml treated groups when compared with the corresponding parameters of the carrier control.

A Styrene-derived polymer having pendent phenoxyanthraquinones for photochromism was prepared by AIBN-initiated radical polymerization. Syntgesus of the monomers was straightforward and the polymer was obtained in 65% yield. Photoinduced rearrangement from the “trans” quinone forms to the “ana” quinone forms readily occurred both in solution and in film when the polymer was irradiated with UV light.

To investigate the effect of Mo and Cu contents on tensile strength of cold drawn stainless steel 304H wires, metallographical and mechanical tests were performed for the wire specimens drawn to different drawing strains at room temperature. It was confirmed that the contents of Mo ana Cu have little influence on the tensile strength of drawn specimens, even though the strain induced martensite transformation decreased with increasing the contents of Mo and Cu. These results were explained by the strengthening of the formed martensite itself due to the solid solution effect of interstitial solutes, carbon and nitrogen. The contents of these elements were slightly higher in the specimens containing additionally added Mo and Cu.

The samples were prepared with hydroxyapatite(HAp) powder and Polycaboxylate (P.C/HAp=10, 15, 20, 25, 30, 35 $wt\%$). The hydroxyapatite green body with Polycaboxylate were obtained by compaction and drying at room temperature for 3hrs. The higher mechanical properties were observed in HAp sample with $35 wt\%$ Polycaboxylate. The average compressive ana bending strength in HAp with $35 wt\%$ Polycaboxylate are $302 kgf/cm^2$ and $213 kgf/cm^2$ respectively. This strength is higher compare to that of the cortical bone.

The changes of chlorophylls and pH of cooked water were investigated in blanched and fermented cabbage. In blanched cabbage, pheophytins were increased markedly with heating time. This was related to the changes of pH and the effects of heat. One minute blanching accelerated the formation of chlorophyllides by the activation of chlorophyllase. In fermented cabbage, pH and chlorophylls were decreased rapidly at the beginning of fermentation. At the final of fermentation, all chlorophylls and chlorophyllides were converted to pheophytins ana pheophorbides, and the content of pheophytins was higher than the content of pheophorbides. The content of pheophorbides in fermented cabbage was higher than that in blanched cabbage.
