분류학적으로 둥글넙치과(Bothidae)에 속하는 표본율 1996년 3월과 1998년 6월에 남해의 광양만과 가덕도 주변 해역에서 채집하였다. 조사 결과, 흰비늘가자미 Laeops kitaharae(Smith and Pope)의 후기 자어와 치어로 확인되었다. Amaoka(1972)의 기준에 의하면, 채집된 4개체는 중-후기 자어(middle metamorphic post-larval stage), 1개체는 후-후기 자어(late metamorphic Post-larval stage)에 해당되었다. 그리고 나머지 2개체는 흰비늘가자미의 치어에 해당되었다. 중-후기 자어는 등지느러미 기조부와 우측 눈부위 사이에 결각이 있는 특징과 등지느러미의 2번째 극조가 긴 사상인 특징에 의하여 후-후기 자어와 구분되었다. 치어의 경우는 소화관이 외부로 노출되어 있지 않은 특징을 보였다. 전-후기 자어(early metamorphic post-larval stage)는 이번 연구에서 채집되지 않았다. Several specimens belonging to the family Bothidae were collected by trawls in Kwangyang Bay and off Kadeok Island in March 1996 and June 1998. These specimens were confirmed to be the post-larvae and juveniles of Laeops kitaharae (Smith and Pope, 1906) that have not been reported in Korea. According to the Amaoka's criterion (1972), four specimens belong to the middle metamorphic post-larval stage, one specimen to the late metamorphic post-larval stage, and two specimens to the juvenile stage. The middle metamorphic post-larval stage can be distinguished from the late metamorphic post-larval stage by the characters such as a notch between foreside of the dorsal fin and dorsal region of the right eye, and greatly elongated second spine of the dorsal fin. In the juvenile stage, the intestine was not externally exposed. However, the early metamorphic post-larval stage was not occurred in this study.

As medical technology progresses rapidly, there is a rise in the average age along with the Korean dietary lifestyle becoming more westernized, which leads to an increase in the number of vascular disease patients in Korea. Thus, we need to manage the medical information of a disease systematically in order to diagnose and treat constructively. However, since there has been no standardized method of man agement to date, a great deal of information could not be properly utilized nor studied. Therefore, the departments of Cardiology, Radiology and Neurology of Samsung Seoul Hospital recently got together to develop an information management system called the Vascular Data System. This program was developed to be run on win98 O/S, upper Pentium Ⅲ, and upper 128 MB Memory, and its source code is Dephi 4.0. It was configured for the user to set the configurations as well as do a variety of search and analysis. If this program were to be updated continuously, it may be used extensively as well as in various parts of clinical research activities.

高珪素-A1 合金의 熱處理效果에 對한 組織을 金屬顯微鏡으로 調査하였으며, 이 合金의 熱處理가 切削速度 및 切削깊이를 變化시키면서 切削加工하였을 때에 素面거칠기, chip 形態, 工具刀面凝着量에 미치는 影響에 對하여 調査檢討하였다. 本硏究를 通하여 얻은 重要한 結論은 다음과 같다. 1) 高硅素-A1 合金의 溶體化 및 時效熱處理는 共晶珪素를 球狀形態로 變化시키며, 材質을 强化시켜 切削性을 현저히 向上시킨다. 2) 移送速度가 一定할때 表面거칠기는 切削速度의 自乘에 反比例하며 熱處理에 의해 그 比例값은 더욱 감소한다. 3) 移送速度가 一定할때 表面거칠기는 切削깊이에 比例하며 熟處理에 의해 그 比例값은 더욱 감소한다. 4) 微細化處理는 工具面凝着量을 감소시키며 熱處理에 의해서 그 量은 더욱 감소한다. 5) 熱處理에 의해 加工面照度는 향상하며, 특히 Mg로 微細化處理한 後 熱處理한 것은 현저히 향상한다. The effects of heat treatment on the structure of high Silicon-Al alloys were examined by metallography. The effects of heat treatment on the surface roughness, the chip formation and the amount of build up edge, after cutting at various cutting speeds and cutting depths were studied. The results obtained are as follows; 1. The heat treatment of the high silicon-aluminum alloy changed eutectic silicon crystal into spheroidal form, the quality of material was intensified and the mechanical properties were improved conspicuously. 2. When feeding speed was constant, the surface roughness was inversely proportional to the square of cutting speed, and heat treatment decreased its ratio greatly. 3. The refining treatment diminished the amount of adhesion to tool surface, and the heat treatment deminished its amount more. 4. When feeding speed was constant, the surface roughness was proportional to cutting depth, and its ratio was much decreased by heat treatment. 5. The illumination of machined surface was improved by heat treatment, especially by heat treatment followed by refining-treatment with Mg. Spheroidizer.
