        단일 밴드 중적외선 영상으로부터 표면온도 추정을 위한 기초연구

        박욱 ( Wook Park ),이윤경 ( Yoon Kyung Lee ),원중선 ( Joong Sun Won ),이승근 ( Seung Geun Lee ),김종민 ( Jong Min Kim ) 大韓遠隔探査學會 2008 大韓遠隔探査學會誌 Vol.24 No.2

        3~5μm 파장대의 중적외선 영상은 화산 활동이나 산불과 같이 고온 현상을 관측하는데 효과적이다. 그러나 중적외선 영역은 지표의 복사율과 대기의 영향으로 인한 변화가 매우 심하고, 특히 낮 영상의 경우 태양 복사량에 의한 영향도 고려해야 하는 어려움이 있다. 따라서 단일밴드인 중적외선 영상을 이용하여 표면온도를 얻기 위해서는 영상이 취득된 시간과 장소에서 관측된 태양 복사량 및 여러 가지 대기 변수가 필요하다. 이 연구는 기존의 다중밴드 기반의 중적외선 영상 활용방법과 달리 단일 밴드 중적외선 영상을 이용하여 표면온도 측정을 위한 기초연구에 그 목적이 있다. 이를 위하여 MODIS 영상을 대상으로 MODTRAN을 사용하여 중적외선 영역의 대기보정 기법을 적용 한 뒤 복사전달 모델을 이용하여 지표의 온도를 측정하였다. 획득된 온도 영상의 정밀도를 측정하기 위해 기존의 온도 알고리즘인 MODIS Sea Surface Temperature 알고리즘에 의해 얻어진 해수온도와 비교를 통하여 오차 원인에 대해 분석을 실시하였다. 두 결과의 온도 차는 낮 영상의 경우 0.89±0.54℃ 밤 영상의 경우 1.25±0.41℃로 비교적 긍정적인 결과를 보였다. 그러나 낮 영상의 육지의 경우 대기에 의한 영향보다 태양빛의 반사가 주된 오차의 원인이 되며 이는 지표 복사율에 의한 영향이 매우 크게 작용하고 있음을 추정할 수 있다. 이 연구는 현재까지 해수에 대한 적용에 국한된 것으로 육상의 경우 복사율 변화가 매우 크기 때문에 중적외선 단일밴드에 의한 온도추정이 매우 어려울 것으로 예상된다. Middle-infrared (MIR) spectral region between 3.0 and 5.0 μm in wavelength is useful for observing high temperature events such as volcanic activities and forest fire. However, atmospheric effects and sun irradiance in day time has not been well studied for this MIR spectral band. The objectives of this basic study is to evaluate atmospheric effects and eventually to estimate surface temperature from a single channel MIR image, although a typical approach utilize split-window method using more than two channels. Several parameters are involved for the correction including various atmospheric data and sun-irradiance at the area of interest. To evaluate the effect of sun irradiance, MODIS MIR images acquired in day and night times were used for comparison. Atmospheric parameters were modeled by MODTRAN, and applied to a radiative transfer model for estimating the sea surface temperature. MODIS Sea Surface Temperature algorithm based upon multi-channel observation was performed in comparison with results from the radiative transfer model from a single channel. Temperature difference of the two methods was 0.89±0.54℃ and 1.25±0.41℃ from the day-time and night-time images, respectively. It is also shown that the emissivity effect has by more largely influenced on the estimated temperature than atmospheric effects. Although the test results encourage using a single channel MIR observation, it must be noted that the results were obtained from water body not from land surface. Because emissivity greatly varies on land, it is very difficult to retrieval land surface temperature from a single channel MIR data.

        외음부의 기저세포암

        김보영 ( Bo Young Kim ),황선정 ( Sun Jung Hwang ),박병준 ( Byung Joon Park ),이은실 ( Eun Sil Lee ),한호섭 ( Ho Suap Han ),김용욱 ( Yong Wook Kim ),김태응 ( Tae Eung Kim ),노덕영 ( Duck Yeong Ro ),이안희 ( An Hi Lee ) 대한산부인과학회 2010 Obstetrics & Gynecology Science Vol.53 No.9

        Basal cell carcinoma (BCC) is the most common human malignant neoplasm, accounting for 75% of all non-melanoma skin cancer. The incidence of BCC is strongly correlated with sun exposure as well as older age. Therefore, the vast majority of BCCs is observed in elderly patients on the sun-exposed skin of the head and neck with a frequency of more than 80%. BCC is very rare on sun-protected skin such as the perianal and genital regions and other etiologic factors must be considered in these cases. Although the pathogenesis of vulvar BCC is unclear, early diagnosis is very important. Because BCC in these areas sometimes seems innocuous, it is recommended that a biopsy of all suspect lesions be performed. We report a woman with BCC of the vulva treated with wide local resection and reviews the literatures on this subject.

        The purpose of this study is to investigate the implications of self-regulated learning. This study investigated metacognitive, motivational, and behavioral factors of self-regulated learning through current research. In general, students can be described as self-regulated to the degree that they are meta-cognitively, motivationally, and behaviorally active participants in their own learning process. Such students personally initiate and direct their own efforts to acquire knowledge and skill rather than relying on teachers, parents, or other agents of instruction. In terms of metacognitive factors, we reviewed the importance of cognitive and metacognitive learning strategies of adolescents for better self-regulated learning. For motivational factors, recent research of self-regulated learning has tended to focus on self-efficacy and goal orientation. The current research examining behavioral factors of self-regulated learning has tended to focus on time management and academic procrastination. Research findings in the motivational aspect suggest that we need to develop the program to improve learners’ self-efficacy and recognize new re-conceptualization of the goal theory. Research findings in the behavioral aspect recommend practical tips and strategies to improve time management skills and to overcome academic procrastination. Finally, future directions for research are discussed.

      • 학교폭력의 이론적 관점에 관한 연구

        방선욱 청주대학교 학술연구소 2016 淸大學術論集 Vol.26 No.-

        School violence has been receiving nationwide attention. In recent years research on school violence including bullying is rapidly increasing. Despite the various efforts of government, high numbers of school violence still continue to occur. I’m convinced school violence must be studied in various perspectives and then alternatives for it have to be carefully prepared. The purpose of this study is to propose an alternative conceptual framework in responding to school violence. Traditionally, the study on school violence has been carried out based on neuro-physiological(frontal lobe cognitive dysfunction, gender differences, neurotransmitter etc.), psychological(aggression-frustration hypothesis, drive reduction theory, self control theory etc.), and sociological(social learning theory, differential association theory, social control theory, social band theory etc.) perspective. To suggest an alternative framework, the following approaches were proposed: One is ecological developmental theory to deal with piecemeal interventions. The other is strength oriented approaches to cope with problem focused measures and to change the school climate. Due to the limitations as an exploratory study, various empirical researches should be followed to test the proposed framework.

        방선욱 청주대학교 학술연구소 2021 淸大學術論集 Vol.36 No.-

        The purpose of this study was to explore the implications for students and teachers of self-regulated learning. This study provided a comprehensive overview of self-regulated learning in relation to metacognition, motivation, and behavior. In terms of metacognitive factors, I reviewed the importance of metacognitive learning strategies of learners for better self-regulated learning. For motivational factors, recent research of self-regulated learning has tended to focus on self-efficacy and goal orientation. The current research examining behavioral factors of self-regulated learning has tended to focus on time management and academic procrastination. Research findings in the metacognitive aspect suggest that we need activities to clarify the concept of metacognition and generalize it to those involved in education. Research findings in the motivational aspect suggest that we need to develop the program to improve learners' self-efficacy and recognize new re-conceptualization of the goal theory. Research findings in the behavioral aspect recommend practical tips and strategies to improve time management skills and to overcome academic procrastination.
