강정호,안기흥,이경로 한국곤충학회 1998 Entomological Research Vol.28 No.1

매미나방(Lymantria dispar)의 발생단계에 따라 JH유사물인 methoprene(isopropyl (2E, 4E)-11-methoxy-3, 7, 11-trimethyl-2, 4-dodeca-dienoate)을 경구처리와 도포처리하여 난소의 미세구조에 미치는 영향을 광학현미경과 투과전자현미경으로 관찰하였다. 다자양형 난소소관으로 이루어진 난소는 복부배면에 1쌍 존재하고 각각 4개의 난소소관으로 구성되었으며, 대조군에서는 전형적인 난세포의 분화가 일어났다. 난황축적이 진행되면서 난모세포 내에는 단백질성 난황, 지질성 난황과 글리코겐 입자들이 다량 함유되어 있었다. 난황축적이 끝난 후에는 난황막과 난각이 형성되어 정상적인 난 성숙을 하였다. 반면 methoprene 처리군은 발육이 억제되어 외형상 난소의 크기와 성숙도가 낮아져 대조군에 비하여 난소소관의 길이와 난세포의 수에서 차이를 보였으며, 난황 축적 등이 제대로 형성되지 않아 정상 성숙과 분화 과정에 연속성을 나타내지 않았다. The cellular effects, especially morphological changes of methoprene (isopropyl (2E, 4E) methoxy-3, 7, 11- trimethyl-2, 4-dodeca-dienoate), the juvenile hormone analogue, in the ovary of gypsy moth, Lymantria dispar were studied with light and transmission electron microscopes. The ovary of Lymantria dispar was composed of 4 polytropic ovariole. In control groups, normal oocytes were fully matured, and then protein yolk, lipid yolk and glycogen particles were formed in cytoplasm. In methoprene treated gypsy moth, egg maturation were not completely controlled. There existed differences in growth of ovarioles between control and methoprene treatment groups. A lot of lipid vesicles and abnormal oocytes were observed in methoprene treatment groups. There were processing of yolk formation, numerous glycogen particle and the shape of protein droplets were changed in methoprene treatment groups.

Methoprene이 매미나방 6령유충의 유리 아미노산 조성에 미치는 영향

강정호,오세원,이경로 한국곤충학회 1993 Entomological Research Vol.23 No.3

유충호르몬(juvenile hormone : JH)이 혈림프의 유리 아미노산에 미치는 영향을 조사하기 위하여 JH 유사물인 mtethoprene (isopropyl (2E, 4E)-11-methoxy-3, 7, 11-trimethyl-2, 4-dodecadienoate)을 매미나방(Lymantria dispar)의 6령유충에 도포처리(topical treatment)와 경구처리(ingestion treatment)를 하여 HPLC로 유리 아미노산 조성을 조사하였다. 혈림프 내의 유리 아미노산은 암, 수에서 모두 14종을 동정하였으며 일부 미지물도 확인되었다. 아미노산의 함량 변화는 glutamine이 가장 높게 나타났으며, lysine, serine, valine 등이 비교적 많은 함량을 보인 반면, glutamic acid, isoleucine, leucine, phenylalanine 등은 낮은 함량을 나타냈다. 총함량은 전체적으로 처리군이 대조군보다 감소하였으며, 수컷이 암컷보다 대조군과 처리군간에 뚜렷한 차이를 나타내 (P<0.1), 수컷이 methoprene의 영향을 더 받는 것으로 확인되었다. The effect of methoprene, a juvenile hormone analogue, on amino acid composition in the hemolymph from 6th instar larvae of the gypsy moth, Lymantria dispar were studied with HPLC. A total of 14 free amino acids were found. Glutamine was the predominent, and lysine, serine and valine were also relatively abundant. Glutamic acid was the least in quantity. Except for ingestion group, the total content of free amino acids in female were high. Amino acid contents of the methoprene treatment group were lower than those of the control group. For significance level 10% (p<0.1), there exist difference between control and methoprement treatment group in male.

강정호,박경혜,김우정,강영준,박주옥,차원철,김권,최태민,강진아,문이상,홍민기 대한응급의학회 2011 大韓應急醫學會誌 Vol.22 No.5

Purpose: This study was undertaken to investigate preventable trauma death and trauma care errors contributing to death on Jeju Island. Methods: A retrospective study was conducted on all trauma deaths between January 2008 and May 2010 at five emergency departments (ED) in Jeju. Of the 165 deaths,101 patients included for study after excluding death within one hour or after one week. Injury severity was scored according to the Injury Severity Score (ISS) and survival probability (Ps) was calculated. Trauma care errors were coded to six categories: pre-hospital, ED, operating room,intensive care unit, general ward, and inter-hospital transfer. In addition, system inadequacy, problems in treatment,diagnosis, and procedures were analyzed. Patient records were reviewed independently and preventability was determined by agreement. Results: The preventable death rate was 35.6%, and the mean ISS was 25.25±10.78. Of all 149 inappropriate cares,66.4% contributed to death. Of the 121 treatment-related problems, 88 problems occurred in the ED. Of the 18 system-related problems, 12 were in the pre-hospital phase. Seventy of the 96 problems associated with deaths occurred in the ED, and 12 of 29 problems in the pre-hospital phase. Conclusion: The preventable death rate was high. Inappropriate care rendered in the treatment process in the ED and system-related errors in the pre-hospital phase were major contributors to preventable trauma deaths. To reduce preventable deaths, more efforts are required on organizing trauma team management and improving care errors during the pre-hospital and inter-hospital transfer.

강정호,오세원,이경로 한국응용곤충학회 1993 한국응용곤충학회지 Vol.32 No.4

짚시나방(Lymantria dispar)의 배자 발생에 미치는 유약호르몬의 영향을 조사하기 위하여 유약호르몬 유사체인 methoprene을 알에 도포처리(topical treatments)하여 부화율, 부화 유충의 생체량 및 알의 단백질과 탄수화물 함량 변화를 조사하였다. Methoprene 농도별 처리는 부화율에 영향을 미쳐 methoprene 처리군이 대조군(78.5%)에 비해 낮은 부화율을 나타 냈으며 5.0$\mul$ 처리군에서 가장 낮은율(42.5%)을 보여 주었다. 부화 직후 1령 유충의 생체량은 대조군이 0.7525mg으로 가장 높았으며 methoprene 농도 처리 순으로 감소하다가 5.0${\mu}\ell$ 처리군에서 0.6487mg으로 최하치를 나타냈다. 처리군별로는 대조군과 0.5$\mul$ 처리군이, 1.0$\mul$와 2.0$\mul$ 처리군의 생체량이 유사하였다. 배자 발생중 알의 단백질 함량 변화에서 0.5$\mul$ 처리군은 2, 4일째 대조군과 뚜렷한 차이를 나타냈으며, 탄수화물도 대조군에 비해 처리군이 낮은 함량을 유지하였다. We investigated effects of a topical treatment of methoprene(0.5-5.0$\mul$/egg), a juvenLle horm mane analogue, on embryo development in the gypsy moth, Lymantri$\alpha$ dispar. Methoprene lowered egg hatching rate, and also reduced the mean wet weights of hatched 1st instar larvae w with the most effect shown at the highest concentration. The differences in protein(p < 0.01) and carbohydrate(p < 0.05) contents between control and methoprene(5$\mul$/ egg) treatment g groups were observed during embryo development.

클라우드 기반의 안전한 국방통합데이터센터 구축방안

강정호,김경민,신규용 보안공학연구지원센터 2017 보안공학연구논문지 Vol.14 No.6

Currently, the Ministry of National Defense of Korea has established and is operating a Defense Integrated Data Center(DIDC) in order to provide a stable defense information service with low-cost and high efficiency. In fact, however, current version of DIDC is a physical aggregation of servers and database systems operated widely in different places without core data center technologies such as integrated security solutions or cloud computing technologies. In this paper, we propose a cloud computing based secure DIDC, called CS-DIDC, which is based on cloud computing, secret sharing, and erasure coding. Under CS-DIDC, individual user can protect his/her own sensitive data regardless of the data protection service provided by cloud service provider(CSP). 현재 국방부는 정보화 예산을 절약하면서도 보다 향상된 수준의 정보기술(IT) 서비스를 제공하기 위해 국방통합데이터센터(DIDC)를 구축해 운용하고 있다. 하지만 현재의 국방통합데이터센터(DIDC)는 기존에 여러 곳에 분산되어 관리되던 서버 및 데이터베이스를 한 곳에 모아 놓은 형태의 물리적인 통합일 뿐 통합 보안기술이나 클라우드(cloud) 기술을 접목한 효율적인 데이터센터와는 거리가 멀다. 이에 본 연구에서는 기존 국방통합데이터센터(DIDC)에 클라우드 컴퓨팅 기술과 비밀공유(secret sharing) 기법, 그리고 삭제코딩(erasure coding) 기법을 접목해 데이터 유출에 대한 안정성을 제공할 수 있는 『클라우드 컴퓨팅 기반의 안전한 국방통합데이터센터 모델』을 제시하고자 한다. 제안하는 안전한 국방통합데이터센터 모델 하에서는 각 사용자가 클라우드 서비스 제공자(CSP)의 역할과 상관없이 자신의 데이터를 안전하게 관리할 수 있다는 장점이 있다.

강정호,부지환,김우정 사단법인 인문사회과학기술융합학회 2015 예술인문사회융합멀티미디어논문지 Vol.5 No.5

Farmers' injuries are more frequent and severe than those in the other job groups. To identify the characteristics of agricultural injuries in Jeju, 119 first aid records and emergency department based injury surveillance system data for four years were analyzed retrospectively. Farmers' injuries in 119 first aid records were 1,947 cases, and mean age of injured patients was 63.9±11.8 years. The proportion of major trauma was 27.4%. The more frequent months of farmers' injuries were from August to October. In comparison between farmers' and non-farmers' injuries, farmers' injuries showed more male proportion (70%), mean age (54.0±17.0 years), and old age proportion (29%) than non-farmers' injuries did, with significance(p<0.001). However, farmers' injuries revealed less usage of 119 rescue transportation (26%) and self-injury proportion (2%) significantly (P<0.001). Further studies including expansion of injury surveillance for agricultural injuries would be needed for in-depth investigation. 농업인 손상은 다른 직업군 손상에 비해 발생 빈도나 중증도가 높다. 제주 지역 농업인 손상의 특성을 파악하기 위해 4개년 동안의 119 구급일지와 응급실 기반 손상감시체계의 손상 자료를 후향적으로 조사하였다. 조사 기간 동안의 119 구급일지 자료 중 농업인 손상은 1,947건이었고, 손상 환자의 평균 나이는 63.9±11.8세였다. 중증외상의 비율은 27.4%였고, 연중으로는 8~10월 농번기에, 일중으로는 일몰 시간에 손상이 많았다. 응급실 손상감시체계 자료에서 농업인 손상은 1,193건이었다. 농업인 손상과 비농업인 손상으로 나누어 비교한 결과, 농업인 손상에서 남자의 비율이 70%, 평군 연령은 54.0±17.0세, 65세 이상 노인 비율이 29%로 유의하게 높았고(p<0.001), 119 구급대 이용율은 26%, 자해 비율은 2%로 유의하게 낮았다(p<0.001). 농업인 손상의 심층 조사를 위해 관련 조사 항목을 확대한 연구가 필요하다.

Cancer of the esophagus and cardia has usually been reported as having poor prog noses. In the Majority of cases reported the main etiologic factors of cancer of the esophagus and cardia remain unknown. In this paper, a clinical review of 130 patients were analysed with particular attension on the some etiologic aspect, age and sex, site of tumor, histological type, esophagographic findings and the thera-rapeutic measures for patients with cancer of the esophagus and cardia. One hundred-thirty cases of the esophageal and cardiac cancer were reviewed with clinical observation and surgical treatment. Esophageal carcinoma was more frequent in men than in women by the ratio of four to one, and the peak incidence occured in the fifth decade. Dysphagia was the most common symptome in 97 percent of our cases. The tumor was located mostly in the middle(46%) and the lower on third(41%). The histological diagnosis was made in 130 cases. Squamous cell-carcinoma was the commonest (75.9%) and the rest was adenocarcinoma in the lower one third (40%). Fifty-five cases were operated on and resection was feasible in fourty-seven patients with 9% (5 cases) of hospital mortality.
