In the post-Cold War era, acquisition technique of high-resolution satellite imagery (HRSI) has begun to commercialize. IKONOS-2 satellite imaging data is supplied for the first time in the 21st century. Many researchers testified mapping possibility of the HRSI data instead of aerial photography. It is easy to renew and automate a topographical map because HRSI not only can be more taken widely and periodically than aerial photography, but also can be directly supplied as digital image. In this study matching size of IKONOS Geo-level stereo image is presented lot production of digital elevation model (DEM). We applied area based matching method using correlation coefficient of pixel brightness value between the two images. After matching line (where "matching line" implies straight line that is approximated to complex non-linear epipolar geometry) is established by exterior orientation parameters (EOPs) to minimize search area, the matching is tarried out based on this line. The experiment on matching size is performed according to land cover property, which is divided off into four areas (water, urban land, forest land and agricultural land). In each of the test areas, window size for the highest correlation coefficient is selected as propel size for matching. As the results of experiment, the proper size was selected as $123{\times}123$ pixels window, $13{\times}13$ pixels window, $129{\times}129$ pixels window and $81{\times}81$ pixels window in the water area, urban land, forest land and agricultural land, respectively. Of course, determination of the matching size by the correlation coefficient may be not absolute appraisal method. Optimum matching size using the geometric accuracy therefore, will be presented by the further work.

The introduction of strategic environmental assessment (SEA) has strengthened and extended the value of environmental impact assessment (EIA) as a foundational tool for sustainable development. In particular, SEA helps to overcome the limitation of project EIA as a 'stand alone' approach, applied relatively late in the decision making cycle. SEA is applied to policy, plan and programme (3P) proposals, when major alternatives are open and systematic consideration can be given to their environmental effects. This process also corresponds to options appraisal of development proposal to find the best practical outcome having regard to all potential impacts. There are imperatives for sustainable development (SD) that are shaping future directions for EIA and SEA internationally, regionally and locally. There is a shift toward more integrative approaches of using EIA and SEA as sustainability tools in cooperated environmental management system (EMS). Korea has established and applied EIA for over twenty years for various projects. Given its coverage, the current EIA system is SEA exclusive. The Prior Environmental Review System (PERS), which is a SEA-type of system, was applied in the late 1990s, mainly for various developing planning programs. The current PERS has been modified as a SEA type system, but in general, policy is not going to be covered.

Soil and Water Assessment Tool (SWAT) model has been widely used in estimation of flow and water quality at various watersheds worldwide, and it has an auto-calibration tool that could calibrate the flow and water quality data automatically from thousands of simulations. However, only continuous measured day flow/water quality data could be used in the current SWAT auto-calibration tool. Therefore, 8-day interval flow and water quality data measured nationwide by Korean Ministry of Environment (MOE) could not be used in SWAT auto-calibration even though long-term flow and water quality data in the Korean Total Maximum Daily Load (TMDL) watersheds available. In this study, current SWAT auto-calibration was modified to calibrate flow and water quality using 8-day interval flow and water quality data. As a result of this study, the Nash and Sutcliffe Efficiency (NSE) values for flow estimation using auto-calibration are 0.77 (calibration period) and 0.68 (validation period), and NSE value for water quality (T-P load) estimation (using the 8-day interval water quality data) is 0.80. The enhanced SWAT auto-calibration could be used in the estimation of continuous flow and water quality data at the outlet of TMDL watersheds and ungaged point of watersheds. In the next study, the enhanced SWAT auto-calibration will be integrated with Web based Load Duration Curve (LDC) system, and it could be suggested as methods of appraisal of TMDL in South Korea.

현재 의료체계의 주된 변화로 근거중심의학(Evidence-based Medicine: EBM)의 전지구적확산을 꼽을 수 있다. 최근 STS 연구들은 EBM이 실제 의학 실행 속에서 어떻게 사용되고 작동하는지에 대한 검토를 수행했는데, 이 글은 이러한 맥락 속에서 전립선암 특이항원(Prostate-specific Antigen: PSA) 의 조기진단 검사 도구 사용 여부를 둘러싸고 미국에서 벌어진 논쟁을 추적한다. 본 연구는 EBM이 PSA 검사 조기진단의 지지자와 반대자 양측에서 논쟁의 자원으로 이용되었으며, 그 과정에서 '확고한 과학적 기준'을 제시할 것으로 기대되던 EBM의 과학적 증거 위계가 행위자들의 의도에 따라 사실상'유연하게' 해석되고 동원되었음을 보일 것이다. 나아가, 이 글은 현재 EBM이 PSA 검사 반대자를 지지하는 것처럼 보이는 일은 삶의 질이라는 가치가 EBM의 체계 내에 주요한 변수로 부상하는 역사적 맥락에 의해 만들어진 결과임을 드러낼 것이다. 본 사례 연구는 EBM 시대에 의료기술에 관한 논쟁을 검토하는 연구자들이 EBM이라는 대상을 주어진 것으로 간주하기 보다는 논쟁 속에서 맥락화하여 논쟁과 함께 분석해야 함을 시사한다.

In spite of variation in coat color, size, and production traits among indigenous Bangladeshi cattle populations, genetic differences among most of the populations have not been investigated or exploited. In this study, we used a high-density bovine single nucleotide polymorphism (SNP) 80K Bead Chip derived from Bos indicus breeds to assess genetic diversity and population structure of 2 Bangladeshi zebu cattle populations (red Chittagong, n = 28 and non-descript deshi, n = 28) and a semi-domesticated population (gayal, n = 17). Overall, 95% and 58% of the total SNPs (69,804) showed polymorphisms in the zebu and gayal populations, respectively. Similarly, the average minor allele frequency value was as high 0.29 in zebu and as low as 0.09 in gayal. The mean expected heterozygosity varied from $0.42{\pm}0.14$ in zebu to $0.148{\pm}0.14$ in gayal with significant heterozygosity deficiency of 0.06 ($F_{IS}$) in the latter. Coancestry estimations revealed that the two zebu populations are weakly differentiated, with over 99% of the total genetic variation retained within populations and less than 1% accounted for between populations. Conversely, strong genetic differentiation ($F_{ST}=0.33$) was observed between zebu and gayal populations. Results of population structure and principal component analyses suggest that gayal is distinct from Bos indicus and that the two zebu populations were weakly structured. This study provides basic information about the genetic diversity and structure of Bangladeshi cattle and the semi-domesticated gayal population that can be used for future appraisal of breed utilization and management strategies.

Background: Despite the existence of established guidelines advocating the use and value of chemotherapy order templates, chemotherapy orders are still handwritten in many hospitals in Lebanon. This manuscript describes the implementation of standardized chemotherapy order templates (COT) in a Lebanese tertiary teaching hospital through multiple steps. Initial Assessment: An initial assessment was conducted through a retrospective appraisal of completeness of handwritten chemotherapy orders for 100 adult patients to serve as a baseline for the project and identify parameters that might afford improvement. Choice of solution: Development of over 300 standardized pre-printed COTs based on the National Comprehensive Cancer Network templates and adapted to the practice culture and patient population. Implementation: The COTs were implemented, using Kotter's 8-step model for leading change, by engaging health care providers, and identifying and removing barriers. Evaluation: Assessment of physicians' compliance with the new practice (122 orders assessed) was completed through two phases and allowed for the identification of areas of improvement. Lessons Learned: Overall, COT implementation showed an average improvement in order completion from 49.5% (handwritten orders) to 77.6% (phase 1-COT) to 87.6% (phase 2-COT) reflecting an increase of 38.1% between baseline and phase 2 and demonstrating that chemotherapy orders completeness was improved by pre-printed COT. As many of the hospitals in Lebanon are moving towards standardized COTs and computerized physician order entry (CPOE) in the next few years, this study provides a prototype for the successful implementation of COT and demonstrates their role in promoting quality improvement of cancer care.

The purpose of this study is to construct an evaluation criteria based on the relative importance and various combinations of each evaluation index and then to appraise urban biotope in terms of nature experience and recreation. After the standard of evaluation had been developed through the review of existing literature, the relative importance of the evaluation index through expert survey was determined, and the evaluation model to assess biotope value was established. The results of this study are as follows; 1) We have constructed the seventeen evaluation criteria through literature reviews, and have provided relative importance to each evaluation index of the natural in biotope, the diversity of landscape patterns, the appearance-existence of water space, the special landscape elements, and the access based on the results of expert survey. and then we have constructed an evaluation system using the relative importance criteria. 2) To evaluate urban biotope using the evaluation system constructed, we selected 14 sites. The final evaluation results of each site is as follows; The first grade areas are the water space with semi-natural style in front of Gangchon Woobang apartments, the forest zone near Page Temple at Mt. Palgong, the edge area of Jisan and Gosan and the tendril yard against Anshim middle school. The second grade areas are Hyomyung elementary school, the farm land behind the third Anshim Jugong apartment, Ehyun put and the swampy land in front of the Kangchon and Anshim construction site. The third grade areas are Seohan and Hwasung high-rise apartments at Beummul-Dong, the Korea Manpower Agency in the Sungseo industrial zone, and the adjacent area of St. Tongil. The only fourth grade area is the commercial zone near Taegu Department Store. 3) It is highly useful to evaluate urban biotope using the evaluation criteria constructed for this research, the evaluation criteria we developed may be difficult to encompass all expert opinion and the period of space-formation is difficult to estimate urban biotopes. In the future, it is necessary to gather the basic data suitable to estimate biotope and it is necessary to develop detailed evaluation criteria applicable to estimate every biotope that has specific property.

교육인적자원부는 ICT 활용 교육을 주도해 나가는데 가장 중심이 되는 교사의 ICT 활용 능력을 신장시키기 위해 다양한 방안들을 수립하여 추진하고 있다. 그러나 현재 시행되고 있는 교사의 ICT 활용능력 신장에 관한 대부분의 노력들은 ICT를 직무활동에 효과적으로 활용할 수 있는 능력보다는 기술소양 능력에 중점을 두고 있다. 그러므로 본 논문에서는 교사의 직무활동을 분석하고, 국내외 교사 ICT 활용능력 평가도구를 비교 분석하여 교사의 ICT활용능력 자기평가 도구를 개발하였다. 또한, 개발된 웹 기반 교사의 ICT 활용능력 자기평가도구를 광주와 전남 지역의 교사를 대상으로 적용하여 성별, 직위별, 지역별, 교육경력별 ICT 활용능력 수준 등을 조사분석하였다.
