본 논문에서는 차량에 설치된 카메라를 활용하여 차선을 추출하고, 차량이탈을 검출하기 위한 방법에 대해서 논의한다. 하드웨어 기술의 발달로 지능형 자동차에 대한 연구가 활발히 진행됨에 따라서, 카메라를 활용한 차선인식 및 차량이탈검출과 관련하여 다양한 알고리즘들이 제시 되었다. 그러나 이들 연구에서는 영상에서 2개의 차선을 모두 찾아야 하기 때문에 처리속도 및 실제 운행환경에서의 다양한 여건으로 인하여 검출률이 떨어진다는 문제점이 있다. 본 논문에서는 빠른 속도와 높은 검출률을 위해 단일차선을 추출하고, 중심점 분석을 통한 차선이탈검출 알고리즘을 제안한다. 카메라의 기하학적 모델링을 통하여 차선이 존재하는 관심영역을 설정하고, 원본 이미지를 이등분한 후에 허프변환(Hough Transform)을 사용하여 한 차선의 일부를 찾아낸 후에, 일정 크기로 복원한다. 복원한 차선을 설정된 중심점과의 거리계산을 통하여 차선이탈을 판단한다. 실차실험을 통하여 제안한 알고리즘을 기존의 알고리즘과 비교 검증을 수행하였고, 이를 통하여 제안된 알고리즘이 빠르고 정확함을 보였다. Lane extraction and lane departure warning algorithms using the image sensor attached in the vehicle are addressed. With the research about intelligent automobile, there have been many algorithms about lane recognition and lane departure warning system. However, since these algorithms require to detect 2 lanes, the high time complexity and the low recognition rate under various driving circumstances are critical problems. In this paper, we present a lane departure warning algorithm using single lane extraction and center point analysis that achieves the fast processing time and high detection rate. From the geometry between camera and objects, the region of interest (ROI) is determined and splitted into two parts. Hough transform detects the part of the lane. After the detected lane is restored to have a pre-determined size, lane departure is estimated by calculating the distance from the center point. On real driving environments, the presented algorithm is compared with previous algorithms. Experiment results support that the presented algorithm is fast and accurate.

목 적: 무정자증 불임부부에서 신선 (fresh) 고환정자 (testicular spermatozoa)와 냉동보존-융해(cryopreserved-thawed) 고환정자를 사용한 난자세포질내 정자주입술 (intracytoplasmic sperm injection, ICSI)의 결과를 비교하고자 하였다. 연구방법: 신선 고환정자 및 냉동보존-융해 고환정자를 사용하여 ICSI 시술을 시행하기로 계획된 총 109주기 (66명)를 대상으로 하였고 신선 고환정자를 사용하기로 계획한 군 (신선 고환정자군, fresh group)에는 92주기 (61명)이 포함되었고 냉동보존-융해 고환정자를 사용하기로 계획한 군 (냉동보존-융해 고환정자군, cryopreserved-thawed group)에는 17주기 (13명)가 포함되었다. 양 군간에 수정률, 착상률, 임신률, 유산률 등 ICSI 시술의 결과들을 비교하였고 통계학적 분석은 Mann-Whitney U 검정 및 Fisher의 정확한 검정을 적절하게 사용하였다. 결 과: 신선 고환정자를 사용하여 ICSI 시술을 시행하기로 계획된 총 92주기 중 9주기에서 고환정자를 추출할 수 없어 시술 주기가 취소되었다. 냉동보존-융해 고환정자군과 비교하여 신선 고환정자군에서 수정률이 높은 경향을 보였고 ($58.0{\pm}27.8%$ vs. $45.9{\pm}25.0%$, p=0.076) 양질의 배아 수는 통계적으로 유의하게 높았다 ($0.9{\pm}1.2$ vs. $0.2{\pm}0.5$, p=0.002). 그러나 임상적 임신율, 착상률, 유산율은 양 군간에 통계적으로 유의한 차이가 없었다. 결 론: ICSI 시술을 위하여 냉동보존-융해 고환정자를 사용하는 경우 수정률 및 배아의 질이 감소하지만 임신율, 착상률, 유산율에는 영향을 미치지 않는 것으로 사료된다. 또한, ICSI 시술이전에 고환정자를 확보하고 냉동보존-융해 고환정자를 사용한다면 난자채취 당일 정자를 확보하지 못하여 주기를 취소하는 경우나 여성배우자의 불필요한 과배란유도를 줄일 수 있으며 반복적인 고환정자추출술로 인한 고환기능의 손상을 줄일 수 있는 유용한 방법으로 사료된다. Objective: To compare the outcomes of intracytoplasmic sperm injection (ICSI) with fresh and cryopreserved-thawed testicular spermatozoa in patients with azoospermia. Methods: One hundred and nine cycles (66 couples) where ICSI was planned with fresh or cryopreserved-thawed testicular spermatozoa were included in this study; Ninety two cycles (61 couples) with fresh testicular spermatozoa (fresh group) and seventeen cycles (13 couples) with cryopreserved-thawed testicular spermatozoa (cryopreserved-thawed group). We compared ICSI outcomes such as fertilization rate, implantation rate, pregnancy rate and miscarriage rate, which were statistically analyzed using Mann-Whitney U test or Fisher's exact test, where appropriate. Results: In 9 out of the 92 cycles where ICSI was planned with fresh testicular spermatozoa, testicular spermatozoa could not be retrieved. Fertilization rate tended to be higher in the fresh group than in the cryopreserved-thawed group ($58.0{\pm}27.8%$ vs. $45.9{\pm}25.0%$, p=0.076). The number of high quality embryos was significantly higher in the fresh group ($0.9{\pm}1.2$ vs. $0.2{\pm}0.5$, p=0.002). However, there were no significant differences in clinical pregnancy rate, implantation rate and miscarriage rate between the two groups. Conclusion: The results of this study suggest that although the use of cryopreserved-thawed testicular sperm for ICSI in patients with azoospermia may reduce fertilization capacity and embryo quality, it may not affect pregnancy rate, implantation rate and miscarriage rate. If testicular sperm can be obtained before ICSI procedure, the use of cryopreserved-thawed testicular sperm may also avoid unnecessary controlled ovarian hyperstimulation and cancellation of oocyte retrieval when spermatozoa cannot be retrieved as well as damage on testicular function by repeated TESE.

In male reproducible health, fertility and IVF (in-vitro fertilization), semen analysis has been most important. Semen analysis can be divided into concentration, motional and morphological analysis of sperm. The existing method which was developed earlier to analyze semen concentrated on the sperm motility analysis. To provide more useful and precise solutions for clinical problems such as infertility, semen analysis must include sperm morphological analysis. But the traditional tools for semen analysis are subjective, imprecise, inaccurate, difficult to standardize, and difficult to reproduce. Therefore, with the help of development of microcomputers and image processing techniques, we developed a new sperm morphology analyzer to overcome these problems. In this study the agreement on percent normal morphology was studied between different observers and a computerized sperm morphology analyzer on a slide-by-slide basis using strict criteria. Slides from 30 different patients from the SNUH andrology laboratory were selected randomly. Microscopic fields and sperm cells were chosen randomly and percent normal morphology was recorded. The ability of sperm morphology analyzer to repeat the same reading for normal and abnormal cells was studied. The results showed that there was no significant bias between two experienced observers. The limits of agreement were 4.1%${\sim}$-3.8%. The Pearson correlation coefficient between readers was 0.79. Between the manual and sperm morphology analyzer, the same findings were reported. In this experiments the slides were stained by two different methods, PAP and Diff-Quik staining methods. The limits of agreement were 7.2%${\sim}$-5.7% and 6.0%${\sim}$-6.3%, respectively. The Pearson correlation coefficients ware 0.76 and 0.91, respectively. The limits of agreement was tighter below 20% normal forms. In the experiments of repeatability, 52 cells stained by PAP and Diff-Quik staining methods were analyzed three times in succession. Estimating pairwise agreement, the kappa statistic for the pairs were 0.76, 0.81, 0.86, and 0.75, 0.88, 0.88 respectively. In this study it was shown that there was good agreement between manual and computerized assessment of normal and abnormal cells. The repeatability and agreement per slide of computerized sperm morphology analyzer was excellent. The computer's ability to classify normal morphology per slide is promising. Based on results obtained, this system can be of clinical value both in andrology laboratories and IVF units.

As research methods, this study would estimate the Net Present Value (NPV), Internal Rate of Return (IRR) and Profitability Index (PI) through an analysis of the feasibility of the case of the Seoul land-leasehold social housing, a type of the community housing and analyze changes in the business value according to the changes of the main factors through a sensitivity to propose a plan for the vitalization of the land-leasehold social housing.As a result of an analysis of the business feasibility of the land-leasehold social housing (Operation for 40 years) selected as the case, the NPV was 11,892,000 won and the IRR was 3.69% and the PI was 1.044. Thus, it turned out that all the indicators in the feasibility analysis secured a business value; however, it is judged that the level is considerably lower for the independence of the private sector. Measures for the vitalization of land-leasehold social housing so that the private sector will be able to be independent in the future can be suggested as follows:First, it is necessary to adjust the land rental rates. The land rental rates taking up the most part as fixed costs affect business feasibility closely. Thus, for the expansion of private business operators’ participation in the project, the adjustment of the land rental rates is needed.Second, institutional countermeasures are needed, so that private business operators can minimize costs and make it possible to provide quality services by realizing the economy of scale in the construction and operation and management.

The present study was conducted to investigate the general epidemiological situations with 18-pullorum infected chickens from Kyongbuk provinces during the period from June 1995 to January 1996. On the Salmonella pullorum isolation tests by rectal swab culture method from infected chickens(386-samples), any Salmonella spp was not isolated from infected live-birds. But 2-S pullorum were isolated of 2-dead chickens(33.3 %) from 6-dead chickens which were positively reacted by serological tests. On the other hand, we could not isolated any Salmonella spp. in any parts of egg-contents; egg-shell, egg-white and egg-yolks with 25-infected bird eggs. On the tests of antibiogram, 2-S pullorum strains were highly sensitive to GM, AM, SXT, CZ, K, F/M, ENR, C, AN, N, NN, LIN+SP, CF, TE and PB, respectively and intermediate sensitive to the CB, CFP, CL, S. P and XNL. But 2-strains were resistant to CC, DP, E, L, OX, TLA and TyLO. In the serological tests, pullorum antibody titers of 18-infected birds was from 2.76 to 9.18 with average by the microplate test. During the 6-months, pullorum antibody average titers were not changed generally. To validate the effects of the antimicrobial agent treatments to the serological antibody titers, infected 6-chickens was medicated with 0.5%-futazolidone. The titer of premedicated birds was average 4.26 but after medication with furazolidone, the titers of treated 6-birds was average 4.08.
