온실가루이의 외부형태적 특징을 주사전자현미경 사진을 통해 관찰하였다. 우선 이들은 포탄모양의 알을 산란하는데 짧은 갈고리모양의 구조에 의해 잎 뒷면에 붙어있는 것이 확인되었다. 촉각의 길이는 0.3㎜로 전체가 6마디로 구성되어 있고, 첫마디는 굵고 짧으며 둘째 마디부터 가늘고 긴 채찍모양을 하고 있다. 끝마디인 6번째 마디의 끝에는 길이가 10㎛정도의 가늘고 비교적 긴 감각기를 가지고 있어 기주를 탐색하는 과정에서 식물체의 표면을 탐지하는데 사용하는 것으로 사료되며, 바로 밑부분에는 길이가 7-8㎛정도의 비교적 굵은 감각기 2개가 존재하고 있는 것으로 확인되었다. 이 감각기는 반대편에는 존재하고 있지 않은 비대칭 분포를 보이고 있으며, 또한 두개의 모양이 서로 상이함으로 볼 수 있다. 이들의 기능은 주로 기주식물을 탐색하거나 후각기능의 화학적 감각기의 역할을 하는 것으로 추정할 수 있다. 섭식행동이 이루어지는 온실가루이 구기는 전형적인 piercing-sucking type으로, 구침이 길게 잘 발달되어 있다. 구기의 끝부분은 10여개의 미세감각기가 분포고 있어 식물체 표면을 탐색하고 맛을 보는 미각기능을 하고 있으리라 추측할수 있다. 구침은 종종 구기에서 분리되기도 하지만, 구침을 잡아주는 지지대가 기부쪽에 자리하고 있음을 알 수 있다. 구침은 두 개의 반원형이 붙어 있는 형상을 하고 있으며, 다른 흡즙형 구침과는 달리 톱날모양의 구조를 볼 수 없었다. 한편 온실가루이의 다리 끝에 붙어 있는 발톱은 식물체에 고정시키기 위한 구조로 보이는 두 개의 갈고리 형태의 발톱과 그 사이에 중앙지지대 형태의 구조인 paranychium을 포함하여 3갈래의 구조를 하고 있다. External morphology characteristics of the greenhouse whitefly, Trialeurodes vaporarium were investigated by scanning electron microscopy. The antennae of the greenhouse whitefly was 6 segments, rod-shape, and 0.3mm length. On the 6th segment, there were many sensilla for searching host-plant as olfactory receptor. The mouthpart of the greenhouse whitefly was a piercing-sucing type, then its stylet was well developed for piercing plant leaf tissue. Claw of the foreleg was a 3-war hook shape including paranychium for attaching plant surface to pierce and lay egg.

The external morphology of Frankliniella occidentalis was studied by using the scanning electron microscopy (SEM). The antenna was consisted of 8 segments and the length of antenna was 0.25mm. The 3rd segment and 4th segment were bent. The 5th segment and 6th segment had sensilla with 7㎛ long. The 8th segment had 8 sensilla. The mouthpart was protruded and distributed many sensilla on there. The leg had no claw.

융비술시 실리콘 고무는 다루기 쉽고 조직 반응이 적어 현대 많이 돌출의 합병증이 생길 수 있다. 저자등은 이러한 실리콘의 단점을 보완할 수 있는 goretex를 사용하여 융비술을 시행하고 비첨에 대해서 자가연골을 이식하여 만족할 만한 결과를 얻었기에 goretex가 안면부 연조직의 증강을 위한 이식재료로 적합하다고 생각되어 문헌고찰과 함께 보고하는 바이다. Many different materials have been used to provide augmentation of the nasal dorsum. this include both autogenous and homogenous materials,as well as allografts. Silicone among the artificial materials has been most widely used. The silicone has some advantages and disadvantages. Goretex(expanded polytetra-fluoroethylene) which has widely used in vascular surgery and abdominal surgery can be used for facial soft tissue augmentation. The author presemts 2 cases of nasal augmentaion using goretex with literature review.

朴東源,徐珍棋 동아대학교 공과대학 부설 한국자원개발연구소 1988 硏究報告 Vol.12 No.2

Binodal curves for solvent(1)-NaCl salt solution(2)-n-propyl alcohol(3) were measured to predict salts effect on ternary solvent(1)-water(2)-n-propyl alcohol(3) without NaCl salt at 25℃, Tie lines were determined from these bimodal curves, and consistency for these data was tested by correlating with Eisen-Joffe equation. NaCl salt solutions were prepared for 5%, 15%, weight percent respectively. It was assumed that quaternany liquid-liquid equilibria with salt were converted to ternary liquid-liquid equilibria without salt if salt were excluded. The bimodal curves with NaCl salt were compared to bimodal curve without NaCl salt. The parameters in the NRTL model and the calculated values of tie line were predicted. Quaternary distribution curves were determined for each salt concentration and salts effect on ternary system were examined.

In this paper, we implemented the hangeul tactile recognition system for the Blind. The system is consist of hardware part and software part.The hardware part is consist of a scanner interface image processing system, a electro tactile output device inter and auser interface. The software system consist of pattern learning routine,image processing and character pattern output routine, file management and operation window routine. The 16 by 16 of return electrode is driven by a electro-tacttile device. The recognition experimention distinguished learning beforefrom learning after,after learning the recognition rate is higher than learning before. As a results of experimentation before and after learning,the later is superior to the former. Therefore,if learning is increased, we can take higher recognition rate.
