Quality and distribution of the TEA(Total Enclosed Area), TSA(Twine Surface Area), solidity ratio and resistance according to the partial nets of the midwater trawl net were examined through experiment at the sea to standardize a design of the midwater trawl net.The results can be summarized as follows;1. The TEA, TSA and resistance of the trawl net were increased definitely according to increasing the scale of the trawl net, and this is the most important factor to design the trawl net.2. As the result of analysis of the distributions of the bag net was smaller than the others. Because TEA for rear end of the wing net is decreased suddenly, we can judge that the trawl net was towed irregularly. 3. The resistance distribution of the partial net was increased suddenly from central part of the bag net and was showed large value in the codend.4. The resistance of the net from the position one of three to gab net and codened charged 75% at all resistance of net.

Calculations for the dissolution behavior of liquid $CO_2$ droplets released in the East Sea and the Clipperton Clarion from a moving ship and a fixed pipeline have been carried out in order to estimate the $CO_2$ dissolution characteristics in the ocean. The results show that the injection of liquid $CO_2$ from a moving ship in a high temperature point is an effective method for dissolution. Also, it is noted that the ultimate plume generated from $CO_2$ bubbles repeatsand shrinking due to the peeling from a fixed pipeline, and the presence of hydrate layer on a liquid $CO_2$ droplet acts as a resistant layer in dissolving liquid $CO_2$.

본 연구에서는 여러 기판에 대한 Cu의 확산정도를 알기 위하여 Ta, Nb, Co/Ta이중층 및 Co/Nb 이중층 위에 기화법으로 증착하고 열처리를 실시하였다. 열처리한 Ta막은 열처리하지 않은 Ta막보다 Cu 확산방지막으로서의 성능이 더 떨어지는데, 이것은 열처리에 의하여 Ta막이 결정화되기 때문이다. Cu/Co/Ta/(001)Si 구조에서의 구리 실리사이드 생성온도는 Cu/Co/Ta(001)Si 구조에서의 그것보다 더 높다. 한편, nb의 Cu에 대한 barrier 특성은 Ta와 비슷한 수준이다. 또한 Cu막 도포 이전에 Pd+HF활성화 전처리나 N2플라즈마 전처리를 실시하면, Cu의 핵생성뿐만 아니라 기판에 대한 Cu막의 접착성도 향상된다.

Stomatal frequency and size of rice plant grown in the different silicon levels of the culture solution in phytotron were observed on both side of the 7th leaf blade. By the application of silicate, stomatal frequency and rates of stoma cell area to the leaf area were remarkably reduced in Milyang 23. It could be considered as favorable characteristics which might be reduced the transpira-tion rate from leaf surface of rice plant besides presence of cuticle-silica double layer in leaf surface.

A scale model net test of the operation of a small two-boat midwater trawl net was performed in the circulating water tank at Pusan Fisheries College. The 1/32 scale model net was constructed after the modelling law of M. Tauti. This type of net is used in Europe for catching sprat like Hering. The net used was 1/32 the actual size. This scale was chosen with consideration for the water tank size. In this experiment, the transfomation of the net shape was observed especially inregard to variations in the height and breadth of the net mouth. These dimensions were varied by changing the breadth of the towing line and the connenting spread.

The basic concept and preliminary performance results of a miniaturized electroosmotic (EO) pump with diaphragms were included in the present study. The separation of an electroosmotic pumping liquid from a drug using diaphragms is mainly to have a freedom in choosing an electroosmotic pumping liquid and to achieve the optimal drug delivery, and, preferably its precise control. We performed maximum flow rate, maximum pressure, and maximum current measurements with and without diaphragm designs. As a result, the effect of diaphragms on pump performance at the maximum condition is small. However, the presence of diaphragms does not allow indefinite continuous pumping.

1. 아한대수의 전형적 지표종인 Sagitta elegans는 동해에서 대마난류축을 제외 하고는 전역에 균등히 분포하고 있으며, 표층 및 수직채집상으로 보아 감포동남방 57리 지점의 다수출현은 잠류남하하는 한류 및 저층냉수의 용승에 기인함을 실증하고 있으며, 한류의 이동은 외양에서는 축산원해에서 표면 이하로 잠류남하하는 것으로 본다. 2. Sagitta bedoti는 전역에 걸쳐, 난류 및 중간수역에서 광범하게 분포되어 있으며 남해측에는 난류역을 피하고 제주서남방 및 서측에 풍부함으로서 냉수역 및 중간수대의 지표종이 되고 있다. 한편 난류성인 Sagitta enflata, Sagitta minima 와 Sagitta serratodentataa, Pterosagitta drace 등은 서해를 제외하고는 광범한 분포상을 시현하고 있으나 특히 남해에서는 난류주류역에 우세하였다. 생태상으로 보아 Sagatta enflata는 순표층성인데 반하여 Sagatta minima는 중층성으로서 난류의 강약 및 유동을 지표하는 종류로서 가치가 크다고 본다. 3. Sagitta crassa는 서해수의 지표종이며 동해 및 제주서남방에 대량출현하여 저철연안수의 특유한 지표역으 맡고 있다.

The coner high column method that is used in the multi-roof building Sungryemoon seems to have been used for the first time during the Choseon Dynasty, and it's characteristics and trend of usage are studied in this paper. In the results, it was confirmed that the coner high column method is economic and structurally safe, and selectively combines the structural factors used in the Chinese seats. It was found that this method was a newly adopted construction method to effectively express the authority of the country with the establishment of a new dynasty. Also the meaning of the method could be guessed since it was continuously used in important structures from the Choseon Dynasty to the Daehan Empire, in spite of the new multi-roof building technologies.

A 23-year-old male patient complained dyspnea on exertion and orthopnea since December 1977. On examination, he was tall and slender. There was grade IV/VI to-and-fro murmur on the left sternal border especially on Erb`s point. The liver was descended 2 fingers breadth below right costal margin. There were no signs of Marfan`s syndrome. Echocardiography demonstrated partial closure of aortic valve and dilated aortic root with enlargement of ascending aorta. Left heart cardiac catheterization revealed moderately elevated pulmonary wedge pressure and right ventricular pressure. The left ventricular end diastolic pressure was markedly elevated to 26 mmHg. On aortography, the aortic regurgitation was severe and it was belonged to angiographically Grade IV. The aortic valve was replaced with Carpentier-Edwards valve without excision and replacement of ascending aorta, under the impression of rheumatic valvular heart disease. After closure of aortotomy, blood pressure was transiently elevated and bleeding from the site of inserting air vent needle of ascending aorta was developed. The bleeding was not controlled by any means. On postmortem microscopic study, the histologic changes were strikingly limited to the ascending aorta from the region of the aortic valve ring.

외이도의 종양은 드물며, 귀지샘에서 기원한 종양은 더욱 흔하지 않다. 저자들은 이루를 동반한 2예의 귀지샘종을 보고하고자 한다. 현미경적으로, 2예 모두 중층 혹은 단층으로 둘러싸인 세관 혹은 샘으로 이루어진 경계가 좋은 종양이었다. 종양세포는 과립성의 풍부한 호산성 세포질을 가졌고, 세포질의 관내 돌출이 관찰되어 아포크린화생을 보였다. 완전 절제후 재발은 관찰되지 않았다. 귀지샘종은 경계가 좋은 양성종양이며, 광범위 절제 치료하지만, 높은 재발율을 보인다. 여기에서 외이도에서 발생한 귀지샘종의 임상적 소견과 함께 병리 소견에 대해 기술하였다.
