Geo-Spatial Information is divided into positional information and attribute information. Up to now, positioning has been fixed by triangulation, traverse surveying and astronomy surveying. Also, satellites are used in position fixing. Road information can be obtained consecutively along the roads. Digitizing from existing maps has been used in obtaining road information. But the roads in existing maps cannot be updated rapidly. Therefore, it is difficult to get informations about new construction roads. This study concentrates on the method of how to use GPS data in the obtaining of road information. There were some errors in comparing the real roads in scale 1:5,000. The errors are caused by the narrow sight angle of satellites.

Fluoxetine is a nontricyclic antidepressant which blocks serotonin reuptake selectively. Its N-demethyl metabolite, norfluoxetine is also selective inhibitor of serotonin uptake. This study was carried out to compare the bioavailability of Myung-in fluoxetine (20 ㎎/cap with that of Prozac?. The bioavailability was conducted on 24 healthy volunteers who received a single dose (80 ㎎) of each drug in the fasting state, in a randomized balanced 2-way crossover design. After dosing, serial blood samples were collected for a period of 48 hours. plasma was analyzed for fluoxetine and norfluoxetine by a sensitive and validated HPLC assay. The major pharmacokinetic parameters (AUC_0-48hr, Cmax, Tmax. AUC_inf.. MRT. T_1/2. Vd and Cl) were clculated from the plasma fluoxetine concentration-time data of each volunteer. The microcomputer program. "WinNonlin' was used for compartmental analysis. A two-compartment model with first-order inpot, first-order output and no lag time was chosen as the most appropriate phamacokinetic model. The data were best described by using a weighting factor of 1/y^2. Though the plasma fluoxetine concentrations of Myung-in fluoxetine were higher than those of Prozac® at all observed time from 7.9% to 16.9% (P<0.05 at 6, 7 and 10 hr), the bioavailability of Myung-in fluoxetine appeared to be bioequivalent with that of Prozac®. There were no statistical significant differences between the two drugs in al pharmacokinetic parameters including AUC_0-48hr of norfluoxetine.

강인준,장용구,강성수 부산대학교 1995 生産技術硏究所論文集 Vol.48 No.-

GPS developed for the strategic equipment by U.S. Deparment of Defence is a navigation satellite system alternative of Navy Navigation Satellite System. So it is not introduced to public. Otherwise, it is used variously in many fields as well as high accuracy surveying network and acquirment of geo-spatial data. The GPS system has been used in static surveying and specialist used its equipment. It is very difficult for unspecialist to use. The GPS system is used to the Car Navigation system and being changed easy equipment for everyone. The GPS system of dynamic surveying is known about 100m accuracy. In this study, it is compared to three GPS system (Pathfinder, Garmin, Svee six) navigated along the road from Pusan Univ. to Haeundae. According to the study, expensive equipment was surveyed to DGPS principle and was very good to acquracy. But, it is able to be processed to real time DGPS. It is difficult to survey by using expensive equipment in the Car Navigation System. Thus, accuracy of the GPS equipment is not higher than it can process datum to real time, the development of software is suitable to make Car Navigation System GPS는 종래의 위성항법체계였던 NNSS와 교체된 새로운 항법시스템으로써 미국방성의 전략장비로 개발되었다. 일반인들에게는 공개되지 않았으나, 현재는 전세계적으로 고정밀 측지망 구성 및 지형정보의 취득에 필수적 장비인 동시에 다양한 분야에서 범용적으로 사용하고 있다. 또한 GPS장비는 정적의 측량에 사용되어져왔기 때문에 일반인이 이용하기에는 상당히 어려웠다. 그러나, 현재에는 GPS장비가 Car Navigation System의 소개로 일반인이 쉽게 이용할 수 있는 장비로 바뀌고 있다. 일반적으로 동적 측량에 의한 GPS장비는 약 100m의 정확도를 가지고 있는 것으로 알려져 있다. 본 연구에서는 부산대학교를 출발하여 해운대까지의 도로를 따라 주행한 세 개의 GPS장비인 pathfinder와 garmin 그리고 SVee Six의 정확도를 서로 비교 고찰하였다. 연구에 따르면, 값비싼 장비는 DGPS를 원리로 측량이 되고 그 정확도도 상당히 좋았다. 그러나, 상당히 고가의 장비는 실시간으로 DGPS가 가능하다. 차량주행을 위한 시스템은 값비싼 장비로는 불가능하다. 따라서, 정확도는 조금 떨어지지만, 값싸고 실시간으로 자료를 처리할 수 있는 GPS장비와 소프트웨어의 개발이 차량주행 시스템 구성에 적당하였다.

지하매설관 조사는 구조물을 설계하고 시공할 때 매우 중요하기 때문에 정확하게 조사하여야 한다. 지하매설관 조사는 도면획득, 현장확인 및 수정, 수치지도작성의 순으로 이루어진다. 도면획득은 지하매설관을 관리하고 있는 각각의 관공서에서 담당하고 있어 각각의 관공서를 방문하여 도면을 획득하여야 한다. 현장확인 및 수정은 현장에서 각각의 관공서에서 획득한 도면과 실제 현장에 있는 지하매설관의 위치를 비교하는 것이다. 수치지도작성은 기존도면과 현장 조사를 통해서 지하매설관들의 정확한 위치 및 선형을 수치지도상에 중첩하는 작업이다. 부산 지하철 3호선 공사는 3구간로 나누어져서 수행되고 있다. 1구간은 대저동에서 미남교차로까지의 구간이다. 2구간은 미남교차로에서 수영교차로까지의 구간이다. 3구간은 미남교차로에서 기장까지의 구간으로 되어 있다. 본 논문은 부산 지하철 3호선 공사를 위한 지하매설관조사의 작업중 생긴 여러 가지 문제점을 고찰하고, 앞으로의 대안을 제시하는데 그 목적이 있다. Underground facilities must be investigated in the importance of construction safety. The investigation of underground facilities consists of acquisitting map, convicting field and correcting map, and inputting underground facilities to digital map. Maps of underground facilities must be acquired from public offices managing maps. Convicting field and correcting map is to compare map acquired by public officials to positions of field underground facilities. Input of underground facilities to digital map is to overlay accurate position and line acquired by field work on digital map. Third Subway Construction in Pusan is divided 3 sections. First section is from DAEJEDONG to MINAM rotary, second section is from MINAM rotary to SUYOUNG rotary, and third section is from MINAM rotary to JIJANG. The purpose of this study is to investigate problems of underground facilities for Pusan third subway construction. As the results this paper propose a substitute proposal in future.

Kang,Mi-Hyung,Lee,Du-Ku,Noh,Tae-Hwan,Shim,Hyeong-Kwon,Na,Seung-Yong,Kim,Jae-Duk 한국자원식물학회 2004 Plant Resources Vol.7 No.1

We used an amplified fragment length polymorphism (AFLP) analysis, a novel PCR-based technique, to differentiate Xanthomonas oryzae pv. oryzae (Xoo) of Korean races. The 6 strains of Xoo K1, K2, K3 races were tested with 81 AFLP primer combinations to identify the best selective primers. The primer combinations were selected according to their reproducibility, number of polymorphic bands and polymorphism detected among Xoo strains. 18 strains of Xoo K1, K2 and K3 races were analyzed with the selected combinations of primer set. Some primer combinations (Eco R I +1 / Mse I+1) could differentiate Xoo of Korean races that were not distinguished by other fingerprinting analysis. Thus AFLP fingerprinting permitted very fine discrimination among different races.

김용구,허지원,김계현,오강섭,신영철 大韓神經精神醫學會 2008 신경정신의학 Vol.47 No.1

Objectives : The EPDS (Edinburgh Postnatal Depression Scale) is a lO-items self-report scale designed as a specific instmment to detect postnatal depression by Cox et al. (1987). This study was to determine the optimal cut-offpoint ofthe K-EPDS for postpartum depression in Korea. Methods : The 239 pregnant women assessed their own psychiatric features with the Korean version of the Edinburgh Postnatal Depression Scale (K.-EPDS), Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), Rosenberg Self-Esteem Scale (RSES) and Marital Satisfaction Scale (MSS) at 6 months ofpregnancy, 1 week after delivery, and 6 weeks after delivery. Subjects above 9 points of K-EPDS at 6 week after delivery were interviewed with Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-I) to confirm postpartum depression. Results : The prevalence of postpartum depression was 12.6% (30/239 pregnant women) in our study. The total scores of K-EPDS at 6 weeks after delivery were higher significantly than those of nonnal group. The score gap of K-EPDS between the depressed pregnant group and the normal pregnant group was increased after the delivery. However, there were no differences in the epidemiological characteristics and the BDI scores at 6 weeks after delivery between groups. Using the AUC (area under the curve), the optimal point to assess the postpartum depression was revealed as 6 weeks after delivery (AUC=85.8%) or 24 weeks of pregnancy (83.7%). The cut-offpoint of K-EPDS to detect postpartum depression among pregnant women was 9/10score of K-EPDS (AUC= 81.8%). Conclusion : In the K-EPDS, cut-off score of 9/10 was optimal to assess the postpartum depression, and K-EPDS at 6 weeks of delivery was more useful than any other point of time. K-EPDS administrated during pregnancy may be a useful tool to find the vulnerability on the postpartum depression.
