이승찬,김도익,김상수 한국응용곤충학회 1995 한국응용곤충학회지 Vol.34 No.3

차나무의 주요해중인 간자와응애에 대한 생활사, 발생소장 및 천적종류에 대해 조사한 결과는 다음과 같다. 간자와응애는 야외 사육장 조건에서 11~12세대를 경과하였으며, 난에서 우화까지의 기간은 여름에는 평균 8.7~13.1일, 봄.가을에는 12.6~24.9일 이었고, 평균 성충수명은 여름에 15.5~21.9일, 봄.가을에 25.1~31.6일, 평균산란수는 여름에 45.1개, 봄.가을에 526.개로 봄.가을에 성충수명이 길고, 산란수도 약간 많았다. 간자와응애의 연중 발생밀도 변동은 4~6월에 가장 높은 발생빈도를 보였으며, 7~8월에 밀도가 급격히 감소하다 10월에 다시 높아졌다. 간자와응애는 3월에 하위엽, 4~6월에는 상위엽, 월동기에는 하위엽을 가해하였다. 간자와응애의 월동은 성충 비율이 높았으며, 각 태가 혼재하여 월동하였다. 간자와응애의 포식성응애로 긴털이리응애(Amblyseius longisplnosus (Evans)), 긴꼬리이리응애(Amblyseius eharai Amitei et Swirski), 왕게응애(Anystis baccarun (L)) 및 Agistemus fleschnen Summers 등 4종중 A. longispinosus (Evans)가 우점종이었다. 그 외에 Scolothrips sp., 애꽃노린재(Orius sauteri Poppius), 께알반날개(Oligota yasumatsui Kistner)등 3종이 분류 동정되어 총 7종의 천적이 조사되었다. These experiments were conducted to investigate the life history and the seasonal fluctuation of population density of tea red spider mite, Tetranychus kanzawai Kishida and to observe its natural enemies in the southern area. Under field-cage conditions, tea red spider mite occurred 11~12 generations. The average periods from egg to adult emergence were 8.7~13.1 days in summer and 12.6~24.9 days in spring and autumn. The average longevities of adults were 15.5~21.9 days in summer and 25.1~31.6 days in spring and autumn. The average number of eggs laid per female were 45.1 in summer and 52.6 in spring and autumn. Tea red spider mite population showed two peaks during April-June, and appeared third or forth peak during October-November. The density of all the stages was the lowest in July through August. Tea red spider mites stayed at lower parts of tea plants in March but they moved to upper parts in April though June, and they again moved to lower parts after autumn. Tea red spider mite overwintered as all stages. Adults were the dominant overwintering stage during this stage. The surveyed natural enemies of the tea red spider mite were 7 species including Amblyseius longispinosus (Evans), A. eharai Amitei et Swirski, Anystis baccarun (L), Agistemus fleschneri Summers, Orius sauteri Poppius, Oligota yasumatsui Kistner and Scolothrips sp.

Comparisons of the resistant strains and susceptible strain based on values were summarized. Using the slide dip and leaf dip techniques with benzomate acaricide, the Keumchun strain of T. urticae showed 75-and 69-fold resistant levels, respectively, as compared with the Kwangju susceptible strain, but the Hackyo strain was 38-and 35-fold resistant levels, respectively. There was no significant difference (P>0.05) between the slide dip and leaf dip methods. With dicofol acaricide, resistant levels of the Keumchun strain of T. urticae were 71 times by using the slide dip and 74 times by using the leaf dip as resistant as the Kwangju susceptible strain while the Hackyo strain was 24 times by the former method and 23 times by the later method. There was also no significant difference (P>0.05) between both the methods. The slide dip technique is more recommendable than the leaf dip technique for determination of degree of chemical resistance to the spider mites with accuracy and less variation of the results. Using the slide dip method with cyhexatin, the Bia, Keumchun and Hackyo strains of T. urticae were 19-, 18- and 9-fold resistant levels, respectively, over the Kwangju susceptible strain.

이승찬,박승하,한승규,윤을식,동은상,정성호,유희진,김덕우 대한성형외과학회 2017 Archives of Plastic Surgery Vol.44 No.5

Background Among the various signs and symptoms of orbital fractures, certain clinical findings warrant immediate surgical exploration, including gaze restriction, computed tomographic (CT) evidence of entrapment, and prolonged oculocardiac reflex. Despite proper surgical reconstruction, prolonged complications such as diplopia and gaze restriction can occur. This article evaluated the prognostic factors associated with prolonged complications of orbital fractures with muscle incarceration. Methods The medical records of 37 patients (37 orbits) with an orbital fracture with muscle incarceration from January 2001 to January 2015 were reviewed. The presence of Incarcerated muscle was confirmed via CT, as well as by intraoperative findings. Various factors potentially contributing to complications lasting for over 1 year after the injury were categorized and analyzed, including age, cause of injury, injury-to-operation time, operative time, fracture type, nausea, vomiting and other concomitant symptoms and injuries. Results All patients who presented with extraocular muscle limitations, positive CT findings, and/or a positive forced duction test underwent surgery. Of the 37 patients, 9 (24%) exhibited lasting complications, such as diplopia and gaze restriction. The mean follow-up period was 18.4 months (range, 1–108 months), while that of patients who experienced prolonged complications was 30.1 months (range, 13–36 months). Two factors were significantly associated with prolonged complications: injury-to-operation time and nausea/ vomiting. Loss of vision, worsening of motility, and implant complication did not occur. Conclusions Patients who present with gaze limitations, with or without other signs of a blow-out fracture, require a thorough evaluation and emergent surgery. A better prognosis is expected with a shorter injury-to-operation time and lack of nausea and vomiting at the initial presentation.

다양한 기저유출 분리 방법을 이용한 4대강 수계의 시간대별 (연·계절·월) 기저유출 기여도 분석

이승찬,김희연,김효정,한정호,김성준,김종건,임경재,Lee, Seung Chan,Kim, Hui Yeon,Kim, Hyo Jeong,Han, Jeong Ho,Kim, Seong Joon,Kim, Jonggun,Lim, Kyoung Jae 한국농공학회 2017 한국농공학회논문집 Vol.59 No.2

The analysis of baseflow contribution is very significant in Korea because most rivers have high variability of streamflow due to the monsoon climate. Recently, the importance of such analysis is being more evident especially in terms of river management because of the changing pattern of rainfall and runoff resulted from climate change. Various baseflow separation methods have been developed to separate baseflow from streamflow. However, it is very difficult to identify which method is the most accurate way due to the lack of measured baseflow data. Moreover, it is inappropriate to analyze the annual baseflow contribution for Korean rivers because rainfall patterns varies significantly with the seasons. Thus, this study compared the baseflow contributions at various time-scales (annual, seasonal and monthly) for the 4 major river basins through BFI (baseflow index) and suggested baseflow contribution of each basin by the BFI ranges searched from different baseflow separation methods (e.g., BFLOW, HYSEP, PART, WHAT). Based on the comparison of baseflow contributions at the three time scales, this study showed that the baseflow contributions from the monthly and seasonal analysis are more reasonable than that from the annual analysis. Furthermore, this study proposes that defining BFI with its range is more proper than a specific value for a watershed, considering the difference of BFIs between various baseflow separation methods.

벼 기계이앙 및 직파재배에 따른 수도 주요해충의 발생.피해

이승찬,마경철 한국응용곤충학회 1997 한국응용곤충학회지 Vol.36 No.2

우리나라 남부지방에서 벼 기계이앙 및 직파재배에 따른 수도 주요해충의 발생피해를 조사한 결과, 끝동매미충, 혹명나방은 기계이앙답에서 다소 많은 발생을 보였으나 벼멸구, 애멸구는 직파재배답에서 더 많은 밸생을 보였다. 그리고 이화명나방, 흰등멸구, 벼줄기굴파리는 그 차이를 인정하기 어려웠다. 조사 해충 모두 기계이앙이나 직파재배보다는 재배시기가 발생 피해에 더 큰 영향을 주었다. 벼멸구, 흰등멸구, 애멸구, 끝동매미충은 재배시기가 늦을수록 발생량이 많았으나, 이화명나방과 혹명나방은 그 시기가 빠를수록 발생피해가 컸다. Studies were conducted to investigate the incidense of insect pests in transplanted and direct seeded paddy fields in southern region of Korea. Population dencities of the rice green leafhopper (RGLH: Nephotettix cincticeps Uhler) and rice leaffolder (RLF: Cnaphalocroch medinalh Guenee) were higher in machine transplanted than in direct seeded, but the brown planthopper (BPH: Nilaparvata lugens Stal) and smaller brown planthopper (SBPH: Laodelphax striatellus Fallen) were abundant in direct seeded. However, no significant difference was found between machine transplanted and direct seeded fields in the incidense of rice stem borer (RSB: Chilo suppressalis Walker), whiteback planthopper (WBPH: Sogatella furcifera Horvath), and rice stem magot (RSM: C'hlorops oryzae Matsumura). Occurrence of rice key pests were affected more by transplanting time than other cultural practices. Later transplanting induced higher populations of BPH, WBPH, SBPH, RGLH. However, RSB and RLF caused higher damage in earlier transplanted paddy field.

갑상선 유두상 암종의 미만성 경화형 변종: 증례 보고

이승찬,김동욱 대한영상의학회 2006 대한영상의학회지 Vol.55 No.1

Diffuse sclerosing papillary carcinoma (DSPC) is a variant of papillary thyroid carcinoma (PTC), but it shows more aggressive clinical course and a poorer prognosis than the other types of PTC. Most PTCs show a focal nodular pattern in the thyroid on the imaging modalities, but DSPC reveals a diffuse infiltrating configuration in the thyroid without any focal nodular lesion. To our knowledge, there are scant radiological reports of diffuse sclerosing variant of papillary thyroid carcinoma. In this report, we present the case of a patient with DSPC who showed the characteristic findings on sonography and computed tomography. 미만성 경화형 갑상선 유두상 암종(DSPC)은 갑상선 유두상 암종의 변종이다. 그러나 갑상선 유두상 암종에 비해 임상경과가 빠르고 나쁜 예후를 보인다. 대부분의 갑상선 유두상 암종은 결절성 병변으로 보이나 DSPC 는 미만성으로 침습적인 형태를 보이며 결절성 병변은 보이지 않는다. 저자들은 저자들이 관찰한 1예의 DSPC에서 관찰된 초음파 소견과 컴퓨터 단층 촬영소견을 보고하고자 한다.

늑막의 원발성 지방육종: 증례 보고

이승찬,성영순,박성근 대한영상의학회 2004 대한영상의학회지 Vol.51 No.1

Primary liposarcomas of the pleura are extremely rare soft tissue sarcomas, for which radiographic findings have been reported in only a few cases. Although liposarcomas occur most commonly in the lower extremities and retroperitoneum, we encountered a case of pleural liposarcoma arising in the right hemithorax, invading the medial basal segment of the right lower lobe. Thus, herein we report a case of primary pleural liposarcoma, along with a review of the literature. 늑막의 원발성 지방육종은 매우 드문 연조직육종으로 이 종양에 대한 방사선학적 소견은 드물게 보고되었다. 지방육 종은 주로 하지와 후복막에 잘 생기는 것으로 알려져 있지만 최근 저자들은 우측 늑막에서 발생한 지방육종이 우하엽 의 내측폐를 침입한 경우를 경험하였다. 이에 저자들은 문헌고찰과 함께 극히 드물게 발생되는 늑막의 원발성 지방육 종을 보고하고자 한다.

동백가는나방(Caloptilia theivora)의 생활사, 발생소장 및 천적의 종류

이승찬,김상수,김도익 한국응용곤충학회 1995 한국응용곤충학회지 Vol.34 No.3

우리나라 주요 녹차재배지에 발생하는 동백가는나방(차굴나방 전가칭. Caloptilia theivora (Walshingham))의 생활사와 발생소장을 조사한 결과는 다음과 같다. 동백가는나방은 야외 사육상 조건에서 년 6세대 경과하였는데, 난에서 우화까지의 평균기간은 봄.가을에는 32.1~38.6일, 여름에는 24.8~32.7일이었으며, 성충수명은 봄.가을에 8.4~14.5일, 여름에는 6.3~8.6일이었고 산란수는 55~71개였다. 유충의 연중 발생소장을 보면, 1992~1993년에는 5월 중순에 발생 peak를 보이기 시작하여 3~4회의 peak가 나타났으나 1994년에는 발생량이 감소하여 초기에는 뚜렷한 발생 peak가 나타나지 않다가 9월 하순~10월 초순에 발생량이 가장 많았으며, 잎에서 용태로 월동하였다. 동백가는나방의 유증기생봉으로는 Stenomesius japonicus (Ashmead). Sympiesis ringoniellae Kamijo, S. dolichogaster Ashmead와 Elasmus sp.등 4종이 채집 동정되었으며, S. dolichogaster가 우점종이다. The life history, seasonal occurrence of larval population and natural enemies of Tea leaf roller (Caloptilia theivora (Walshingham) were investigated in field-age. C. theivora had 6 generations a year. The developmental periods from egg to adult emergence were 32.1~38.6 days in spring and fall, and 24.8~32.7 days in summer. The average longevities of adults were 8.4~14.5 days in spring and fall, and 6.3~8.6 days in summer. The average number of eggs laid by a female were 55~71 throughout the season. Larval population density of C. theivora showed 3~4 peaks from middle may in 1992 and 1993. However, population density of 194 was pretty low in early season and exhibited a peak in late September-early October. C. theivora overwintered in pupal stage on the leaves. Four hymenopterous parasitoids of C. theivora larvae were identified ; they are Stenomesius japonicus (Ashmead), Sympiesis ringoniellae Kamijo, Elasmus sp., and S. dolichogaster Ashmead which is dominant.
