정미정,박영립,김영근 순천향대학교 1994 논문집 Vol.17 No.2

멜라닌 극세포종은 각질형성세포와 멜라닌 세포의 중식으로 이루어진 양성종양으로 호발부위는 두부, 경부, 안면, 체간 및 하지 등이며 비호발부위인 둔부에 발생한 경우도 있다. 환자는 44세 남자로 비호발부위인 외이개부(right auricle)에 1년전 부터 발생한 2×1㎝ 크기의 자각증상이 없는 검은 판을 주소로 내원했다. 과거력 및 가족력상 특기소견 없었으며 내원당시 시행한 검사소견상 일반혈액검사, 소변검사, 전해질검사, 매독혈청반응, 흉부 X-선검사, 심전도 검사 등에서 모두 정상 또는 음성반응을 보였다. 피부병변 부위에서 시행한 조직검사상 표피에는 중등도의 과각화증, 국소적인 이상각화증, 멜라닌 세포 및 각질형성세포의 증식으로 이루어진 극세포종, 가성각질낭종(pseudo-horn cyst) 을 보이고 있으며 멜라닌 색소 및 멜라닌 색소를 함유하는 세포집단이 표피층에서 다수 발견되고 유두진피에는 경한 림프구 침윤과 멜라닌 식세포가 발견되었다. 강확대소견상 종양은 기저세포와 유사한 호염기성 세포, 편평상피세포 및 멜라닌 세포로 이루어져 있었고 멜라닌 세포는 표피 전층에서 관찰되었다. Fontana-Masson 염색에서는 검게 염색된 멜라닌 함유 세포들이 표피전층에서 발견되었다. 병변의 전기소작술 시행후 3개월간의 추적관찰에서 재발의 징후는 보이지 않았다. 이상의 특징적인 임상양상과 병리조직학적 소견상멜라닌 극세포종으로 진단하였으며 병변 발생부위가 희유한 1예를 경험하였기에 보고한다.

뇌 수막종의 Volume Rendering 영상과 고식적 혈관 조영술의 영상 비교

This study showed following results. The time interval for maximal enhancement of meningioma was 120∼180 sec after injection of contrast material. All 12 cases showed good relationship between the tumor and surrounding vessels. A case of aneurysm associated with tumor was also well visualized. Three-dimensional volume rendering imaging of meningiomas obtained by using double contrast-enhancement technique was effective in the evaluation of relationship between the tumor and adjacent vascular structure. This technique was considered to be useful in making the preoperative plan.

다중로봇 협업 기반의 양팔로봇을 위한 시스템 UI 기술 설계 및 구현

김영근,정준영,구교민 제어로봇시스템학회 2014 제어로봇시스템학회 국내학술대회 논문집 Vol.2014 No.5

In computer programming, an application framework consists of a software framework used by software developers to implement the standard structure of an application. This paper introduces System UI for Dual-arm robot system based on multi-robot cooperation. System UI have WYSIWYG script editor that named Job planner for making Job script files. This editor can create by Icon based diagram type GUI that runs for a robot used for manufacturing process system.

The common strategy of speed control of single-phase induction motors depends mainly upon controlling the applied voltage on the motor. Changing the applied voltage on the motor can be effected by several techniques. Some on these techniques auto-transformers or adding extra winding, as required, to either the main or auxiliary winding. The other approaches use power electronic devise such as TRIAC. Each one of these schemes has and demerits. Single-phase induction motors are always small and are seldom built in sizes over fractional horsepower ratings, In view of this, they are deprived from controlling their speed by expensive drives which employ frequency control; a matter which offers a wide range of speed control. However, if the input supply frequency to a single-phase induction motor is controlled by a single controlled forced commutated device. Certainly, the event will be a remarkable achievement. This approach is the essence of the present paper. The paper presents a new drive for single-phase induction motor. This drive bridge rectifier connected with the stator in a non-conventional fashion. The speed of the single-phase induction motor is controlled by controlling the chopping frequency of the chopper switch. The attractive feature of the drive is that it effects doth frequency and do chopping simultaneously. The drive performance has received both theoretical and experimental investigation.

Red sorrel, as one of exotic weeds in Korea, was introduced along with imported cereals for concentrate feed or within the seed for forage production. The plant was dominated in grassland and reduced the quality of forage. In particular, this weed cause severe problem in alpine grassland. This study was carried out to investigate the effect and response of red sorrel and forage crops by foliar and soil applied herbicide application. Mecoprop(MCPP) and pendimethaline were selected by pre-field experiment trials and applied to control the red sorrel in grassland. herbicidal activity of MCPP was 77.2% at 500㎖/10a level and 82.8% at 750㎖/10a level. However, seedling growth of germinated red sorrel. The herbicidal activity of pendimethalin to the red sorrel seedling was 83.0% 2 times application of MCPP at the rate of 750㎖/10a was effective to control of red sorrel regrown from root and herbicidal activity was 93.2% MCPP and pendimethaline treatment was not reduced growth of grass and have no herbicidal injury to forage crop seedling. Amount of MCPP and pendimethalin remained in grass plant was decreased from 20 days after after herbicide treatment and could not be problem in livestock feeding.

¹³³Xenon을 利用한 皮膚瓣의 血流量測定에 關한 實驗的 硏究

Various tests to measure the circulation in skin flap have been proposed such as the histamine wheal test, the atropine test, the nicotinic acid test, plethysmography, thernography, and the fluorescein dye test. If a simple and accurate method could be developed to quantitatively determine the regional blood flow in the skin flap, such a method would have a great significance in plastic and reconstructive surgery. Measurment of blood flow in a tissue on the basis of the observation of the clearance rate of a radioactive isotope injected directly into that tissue has been developed since Kety's report. By contrast with other radioactive isotopes, ¹³³Xe diffuses freely across cell membranes, and therefore local blood flow can readily and accurately be calculated. A study was made to determine the local blood clearance rate of experimental flap of rabbits using local clearance method of ¹³³Xenon (¹³³Xe). A total of 40 rabbits, 3.0-4.0kgm were dividid into control, 1:4 and 1:6 skin flap groups. ¹³³Xenon disolved in sterile saline was injected intracutaneously in a concentration of about 100μCi/㎖, amuont 0.1㎖. The detector(gamma counter) was placed at a distance of 10cm from the skin surface. At various intervals, the clearance rate of ¹³³Xenon was checked by detector and blood sampling from femoral puncture. The following results were obtained, 1) ¹³³Xe clearance rates were the greatest in the control group, the next in the group of 1:4 skin flap and the lowest in the group of 1:6 skin flap. 1:4 skin flap and the lowest in the group of 1:6 skin flap. 2) The changes of radioactivity of ¹³³Xe in the control group were more rapidly decreased during 60minutes after injection of ¹³³Xe, thereafter slowly decreased. The changes of radioactivity of ¹³³Xe in the group of 1:4 skin flap were slowly decreased during 2 hours after injection of ¹³³Xe, thereafter revealed plateau in nature. The changes of radioactivity of ¹³³Xe in the group of 1:6 skin flap were slowly decreaseed during 60 minutes after injection of ¹³³Xe, rapidly decreasd between 60 minutes and 120 minutes, thereafter showed plateau in changes. 3) The degree of flap necrosis in the experimental groups of the skin flap was larger in the group of 1:6 skin flap than in the group of 1:4 skin flap.
