본 논문에서는 지구표면의 99% 지역의 3차원 DEM 정보를 제공하고 있는 ASTER DEM 과 SRTM DEM의 실용가능성과 정확도를 분석하기 위해 1:5000 수치지형도에서 추출한 등고선을 통해 DEM을 생성하여 ASTER DEM과 SRTM DEM의 정확도를 평가하고자 한다. 먼저 이를 위하여 한반도 지형특성을 고려하여 명지(안양), 산악지역과 평지가 적절하게 분포하고 있는 지역(진안), 산악지역(속초)을 연구대상지역으로 선정하였다. 또한 대상지역의 1:5000 수치지형도를 통해 DEM을 생성하고 통일한 지역의 ASTER DEM과 SRTM DEM을 취득하여 상호 중첩비교가 용이하도록 수치지형도 DEM과 동일한 15m의 해상도로 변환하였다. DEM의 정확도툴 평가하기 위해 수치지형도의 등고선을 기반으로 구축된 DEM을 기준으로 ASTER DEM과 SRTM DEM의 RMSE, 상관계수, scatter plot을 이용하였다. 분석결과 수치지형도 DEM과 ASTER DEM, SRTM DEM 모두 높은 정확도를 나타내었으나, 상대적으로 SRTM DEM보다 더 넓은 범위의 자료를 제공하는 ASTER DEM이 높은 정확도를 보여 향후 다양한 분야에서의 활용이 기대된다.

The conventional urodynamic monitoring is fulfilled by artificially filling a bladder with saline. Generally. it is difficult to evaluate the physiological functions of the storage and voiding of a bladder. With this aim, we constructed an ambulatory urodynamic monitoring (AUM) system and proposed a novel method estimating abdominal pressure by measuring bio-impedance variations. Our system was clinically evaluated for 10 patients. It turned out to be that as the intensity of the abdomen contraction increased, the amplitude of bio-impedance signal and the RMS value of EMG increased more as compared to those who observed during the rest mode. Also, we determined the optimum electrode pair for estimating the abdominal pressure using bio-impedance method and consequently compared with the conventional methods. Because impedance changes differ from a weight, a height, contractile force, volume of muscle and blood other or whatever of individuals, it was quantified in terms of impedance change, correlation coefficient and SNR Our results showed the optimum electrode pair (1,9) which could detect impedance changes due to the increase of the intensity in the abdominal pressure. The correlation coefficient and quadratic function between the RMS values of EMG and the impedance changes were 0.87 and $y=0.0014x^2+0.0620x+0.6958$, respectively. Thus, our system demonstrated that the abdominal pressure could be measured noninvasively and conveniently by simply estimating bio-impedance values. We propose that this optimum electrode configuration would be useful for the future studies involving the handy measurements of abdominal pressure with our suggested ambulatory urodynamics monitoring system.

This study was designed to analyze the research methodology and the key concepts used in articles published in each nursing journal of seven branches of the Korean Academy of Nursing. The purpose of this study was for reflecting the trends of nursing research and suggesting the direction of future nursing research in Korea. One thousand three hundred seventy two articles published in seven nursing journals from the beginning year of 2000 were analyzed. The prevailing research designs for these journals were the non- experimental design ranging from 54.3% to 75.7%, the experimental design ranging from 6.2% to 30.4%, and qualitative research design ranging from 3.7% to 10.6%. Research subjects were 10.0% to 46.0% for clients with health problems, 2.1% to 42.4% for generally healthy persons, 1.4% to 43.9% for primary care- givers, 7.0% to 53.5% for nurses or nursing students, and 3.1% to 7.3% for health organizations or nursing organizations. The data collection method used most often self-report questionnaires using psychosocial measures. Interviewing methods and physiologic measures were used relatively few times. The domains of the key concepts that prevailed was personal domain and health domain. This study has the limitation of focusing on only the superficial structural analysis rather than in-depth content analysis of each article. However, this study is the first study for reflecting the trends of nursing research based on each journal of seven branches of the Korean Academy of Nursing.

Purpose: The purpose of this study was to investigate impact of sexual knowledge and sexual self-efficacy on sexual autonomy in middle school students in a rural area. Methods: With a cross-sectional descriptive design, 236 second-grade students were recruited from 4 middle schools using convenience sampling. The instrument was a self-administered questionnaire on sexual knowledge, sexual self-efficacy, and sexual autonomy. Data were analyzed using 2-sample t-test, one-way ANOVA, Scheffe, Pearson correlation coefficient, and stepwise regression. Results: Results showed significant positive correlations among sexual knowledge, sexual self-efficacy, and sexual autonomy. Sexual self-efficacy and sexual knowledge explained 37% of the variance in sexual autonomy. Conclusion: Findings of this study suggest that it is relevant to address sexual self-efficacy as well as sexual knowledge in order to increase sexual autonomy in middle school students. Further studies are warranted to investigate these variables with a larger sample and for development and validation of interventions to enhance sexual self-efficacy and sexual autonomy in middle school students.

Purpose: The purpose of this study was to compare stress levels of elementary students according to three regional levels: a large city, a medium-sized city, and a rural area. Methods: This was a descriptive comparative survey using a convenience sample of 1,161 5th-and 6th-grade students. The stress level was measured by a stress scale that consisted of 65 items regarding personal characteristics, family, school, and peer factors. The data were analyzed by ${\chi}^2-test$, t-test, ANOVA and multiple regression using the SPSS 10.0 statistical program. Results: Overall, the mean stress scores reported by the participants were near the middle of a 5-point scale and the level of family-related stress was highest, followed by peer, school, and individual-related stress. Sixth-graders and female students showed higher stress levels than 5th-graders and male students, respectively. The participants reporting unsatisfaction with their lives and those living in large cities tended to have significantly higher stress levels. Conclusion: Grade, gender, life satisfaction, and regional levels were all significant factors associated with high stress levels among elementary students. Development of stress management programs for this specific population, especially targeting students who are female and living in large cities, is needed.
