송연경 한국지리정보학회 2005 한국지리정보학회지 Vol.8 No.1

다중센서 결합에 의한 외부표정요소 결정기법은 항공기에 탑재한 GPS 와 INS로 센서의 위치와 회전각을 정확히 결정함으로써 외부표정요소 결정을 위한 지상기준점 측량을 생략하거나 또는 최소한의 기준점만을 사용하여 외부표정요소를 결정할 수 있으며, 이에 따라 지형도 제작에 대만시간과 경비를 크게 절감할 수 있다. 따라서 본 연구에서는 다중센서 탑과 동시에 CCD 카메라를 탑재하여 동시에 측량을 하고, 외부표정요소 직접결정 기법에 의한 CCD 영상으로 수치정사영상을 제작하였다. 본 연구에서 제작된 결과물에 대한 정확도 검증을 위하여 GPS로 측량한 지상 검사점을 기본으로 하여 외표정요소 직접결정 기법에 의하여 제작된 수지정사영상의 위지 정확도를 평가하였다. 수치정사영상은 소수의 기준점을 사용한 경우와 기준점을 사용하지 않은 경우의 두 가지로 세자하였다. 다중센서에 의한 제작된 수지정사영상의 정확도는 소수의 기준점을 사용한 경우, 축적 1:1,000 지도의 정확도 기준을 만족시켰으며, 기준점이 없이 제작된 정사영상의 정확도는 축적 1:5,000 지도의 정확도 기준을 만족함을 알 수 있었다. Direct Georeferencing by combined multi-sensor based on the direct measurement of the projection centers and rotation angle of sensor through loading the GPS and INS in aircraft. The method of combined multi-sensor can offer us to acquire the exterior orientation parameters with only minimum GCPs, even the ground control process could be completely skipped. Consequently, It is possible extreme to reduce the time and expense for the mapping process. In this study, a CCD camera is simultaneously used in combined multi-sensor surveying, and acquired CCD image through Direct Georeferencing produce digital orthoimage. In this process, methods of combining sensor and digital orthoimage are examined and estimated. For the comparison of the positioning accuracy digitalorthoimage through Direct Georeferencing, GCPs determined by GPS surveying are used. Two digital orthoimage are produced; one with a few GCP and the other without them. The accuracy of orthoimages produced through combined multi-sensor with GCPs meets that of 1:1,000 maps. Without GCPs, it meets that of 1:5, 000 maps.

Clinical observation was made on 52 cases of Stroke that were confined through brain CT, MRI scan. The Stroke cases wee classified into the following kinds cerebral infarction, cerebral hemorrhage, cerebellar or brain stem infarction, cerebellar or brain stem hemorrhage. and among the 52 cases of Stroke cerbral infarction was noticed in 75.00%, cerebral hemorrhage in 11.54%, cerebellar or brain stem infarction in 9.52%, cerebeller or brain stem hemorrhage in 3.85%. The ratio between males and females was 1.74:1 in the whole groups of Stroke and most cases were over 60 of age. As the time of hospitalization, most patients hospitalized from 1 day after stroke to 7 days after stroke. And as the course of hospitalization, most patients hospitalized first. Among the preceding disease at the onset of Stroke hypertention was noted in 32.69%, and deabetes mellitus or heart problem was noted frequently(15.39%). Electrocardiography findings were as follows: The normal was noted in 53.85%, the abnormal in 46.15%. And as the abnormal, left ventricular hypertrophy was noted in 17.54%. The predisposing factors or conditions at the onset of brain infarction were usually initiated during the time of sleeping and those of brain hemorrhage chiefly during the time of execising like overwork or walking etc. It was noted that smoking a pack of cigarette showed highest disease rate(33.33%) among the average of smoking amount of one day in case of man. Prior to attack, the most chiefly complain was dyspnea or discomfort on chest region. And 30.70% of patients had no previous sign. There were a large number of recurrent cases. The first attack was noted in 71.15%, the 2nd attack in 23.08%, the 3rd attack in 5.77%.

저자들은 특별한 위험 인자 없이 심한 허리 및 왼쪽 둔부 통증으로 내원하여 황색포도알균에 의한 균혈증이 진단된 젊은 여성에서 드문 감염질환인 화농성 천골장골관절염과 엉덩근 및 엉덩허리근 농양이 발생된 예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Pyogenic sacroiliits is a rare disease and the diagnosis is difficult because of unawareness of the disease and nonspecific symptoms and signs mimicking septic hip, iliopsoas muscle abscess and herniation of intervertebral disk. There are some predisposing factors related to the disease like trauma, pregnancy, intravenous drug abuse and infection of other systems such as skin, genitourinary system and heart. Staphylococcus aureus is the most common causative bacteria. Here we describe a case of 27-year-old woman presented with acute onset of back and left buttock pain. Bone scintigraphy revealed increased uptake at left sacroiliac joint and computed tomography of the pelvis showed left sacroiliitis with left iliacus and iliopsoas abscess. There was no history of usual predisposing conditions. S. aureus was grown from blood cultures and the patient improved with 2 weeks of intravenous cefazolin followed by 4 weeks of oral clindamycin treatment.

몬트리올 의정서에 의해서 규제받는 Halon-1301과 대체 물질중의 하나인 CO_2의 물성(밀도, 점도, 엔탈피)의 실험식을 구하였다. 문헌에서 얻은 실험값을 이용하여 온도에 대한 회귀분석에 의해서 실험식을 얻었다. 압축인자를 이용하여 온도에 대한 2차 함수로서 밀도에 관한 실험식을 제안하였다. 점도는 온도에 대한 지수함수로 표시되며, 보정인자를 사용하여 사용 온도범위를 확장하였다. 엔탈피는 열용량과 마찬가지로 온도에 대한 2차 함수로 정의하여 나타내었다. 본 연구에서 제안된 위의 실험식의 상관계수는 0.99이상이었다. For Halon-1301 regulated by Montreal Protocol and CO_2 as its alternatives, the empirical equations of density, viscosity, and enthalpy were correlated in terms of temperature. They were obtained by regression analysis from the experimental data in the literature. The empirical equation of density was expressed as compressibility factor by the second- order function of temperature. The empirical equation of viscosity was formulated as a power function, and a correction factor was considered to cover the wider range of temperature. Finally, heat capacity as well as enthalpy were well fitted by empirical form of the second-order temperature. The correlation coefficients of the equations in this work were more than 0.99.

To evaluate the specificity of restriction fragment length polymorphism (RFLP) of Newcastle disease virus (NDV) fusion (F) protein gene for various NDV strains. F protein genes of NDV CBP-1 isolate, LaSota, B1 and Kyojungwon (KJW) were amplified by reverse transcriptase-polymerase chain reaction (RT-PCR) and RFLP were examined. In RT-PCR using F primer sets for 1.7 kb F gene, the amplified products were observed in CBP-1, LaSota and B1 except KJW. However, F2 primer set for 521 bp yielded the amplified bands with all strains. The amplified F genes (1.7 kbp) were treatd with 15 different restriction enzymes to analyze RFLP and the cleavage patterns. CBP-1 showed various cleavage patterns with 8 enzymes, LaSota, with 11 enzymes and B1, with 11 enzymes. According to the cleavage patterns, the physical maps were constructed, and it was found that CBP-1, LaSota and B1 strains had specific cleavage sites with HinfI, XbaI and XhoI. These findings suggest that RFLP are worth applying in the diagnosis and molecular epidemiological studies of Newcastle disease.

This study was conducted to evaluate the effect of hydraulic retention time, volatile solid loading and COD loading in waste activated sludge treatement by single and two stages anaerobic digestion on volatile solid removal efficiency and gas production. As the result, with increasing volatile solid and COD loading, or decreasing hydraulic retention time, volatile solid and COD removal efficiency were decreased. Hydraulic retention time, volatile solid loading and COD loading for effective operation were each 13 days, 1.5kg VS/㎥ ·day and 1.5kg COD/㎥ ·day. Two stage digestion was superior to single stage digestion in terms of volatile solid and COD removal efficiency, but this difference was quite small. With decreasing hydraulic retention time, organic acid concentration was increased but bicarbonate alkalinity was decreased.

Nowadays it is necessary to manage the road system effectively because of the explosive increment of vehicle and goods. To resolve this problems through the fast upgrade of information about position and time of moving vehicle, the combined navigation system using GPS and complementary navigation system, i.e. INS, DR, etc. has been used. Although GPS is popular for the vehicle navigation system, this is not useful for the kinematic positioning of the vehicles in the urban canyon because of its few satellites. Therefore, this study deals with the kinematic positioning of the vehicles with GPS CORS to GPS navigation. For this, first the static single point positioning of GPS and GPS for reference station was performed to evaluate the accuracy of GPS positioning. Next, in the post-processed, the DGPS(Differential GPS) was performed for the kinematic positioning of the vehicles. So, it is expected that GPS CORS can be applicable to the control of traffic flow, the effective management of road system, and the development of ITS and it is regarded that the combined navigation system of vehicles with GPS, INS, and DR, etc. should be studied constantly.

The purpose of this study was to investigate how preceptor experience has an effect upon preceptor nurses. This study was so designed that it could compare the difference between clinical performance and Job satisfaction of preceptor nurses and those of nonpreceptor nurses. Study subjects were sampled out from those nurses who worked with two university hospitals where preceptor programs were implemented. The number of subjects totaled to 134, including 69 preceptor nurses and 70 nonpreceptor nurses. The score of preceptor nurses' clinical performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. Among all of the preceptor nurses, the highest number of preceptor experience was just one time. Except for five times in preceptor experience, the more the number of times of preceptor experience, the higher score in clinical performance. It was manifested that the number of preceptor experience was not related to job satisfaction. The score of preceptor nurses' clinica1 performance and job satisfaction revealed a higher value than that of nonpreceptor nurses. A similar result was also shown in the subdomains. However these difference were not statistically significant. The reward that preceptor nurses wished most was a reduction of the work load assigned to them. Currently preceptor nurses are only receiving a small quantity of financial reward related with their preceptor role. Most of preceptor nurses (96.8%) were not satisfied with their existing reward. Almost half of the preceptor nurses(43.5%) did not want to play a role as preceptor again. The reason why the scores of clinical performance and job satisfaction were low might be attributed to the inadequate preceptor training program and reward system. Appropriate knowledge and clinical skill are expected to enhance the level of preceptor nurses' clinical performance and appropriate internal and external reward to elevate the level of preceptor nurses' Job satisfaction. Therefore, it is needed for us to develop more effective preceptor education program, financial reward, support of colleague nurses and nursing managers, and adjust workload for the purpose of more effective preceptor programs.
