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.

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.

Peptic disorders are among the most common maladies in korea as the world. In most cases their etiologies not be established and their pathophysioolgy remain obscure. Although the persence of fastric bacteria has been logn established, recently campylobacter pylori seems to be etiologic agent of peptic disorders. Campylobacter pylori is visualized in most cases of peptic disorders and not visualized after treatment of bctericidal agents, bismuth compound or metronidazole. We had a following results for identification of campylocacter pylori in stomach and duodenal mcuosa via endoscipc biopsy. 1. We studied 54 patients who had dyspeptic symptoms, 29 males. 2. Most patients are in 5th decades, next in 3rd and 6th in order. 3. Ptients were composed of 27 peptic ulcer, 22 gastitis and 5 gastric carcinoma. 4. Campylobacter pylori was identified in 69% of total patients, peptic ulcer 63%, gastritis 77%, stomach carcinoma leastly.

The structures of catholic churches have multipurpose functions in a single one ; not alone for ritual but for congregations, educations and habitations. As a result rationally interdependent arrangement will be the keystone of styles of architecture and forms for church buildings under the control. Especially the entrance of modern catholic church buildings are for the alpha and omega of various events, -religious ceremonies, educational works, congregations and habitations, and fill the role of rooms for intermediate- space. These entrance of catholic churches reflect the architectural design of building engineers. This study in on the various purposes of the entrance in modern architecture of catholic churches, and this also shows the relation between the entrance and the rooms for special activities of each part. The derived for this study are as follows. 1. Catholic church edifices have fast increased in number since the 1980's in accordance with the expansion of religious influence, but the rate of increase has started slowing down from 1990. 2. Catholic church edifices have tendency to be constructed in a multi purpose singular structure-more than 3000㎡ high-storied massive building in a limited space thanks to having difficulty securing the sites for churches. 3. The way of using the space for religious ceremonies as the inside and outside stairway has increased since 1980. 4. The means of access to the inside by using the outside stairway show overwhelming preponderance among separate church buildings. 5. Partly-interlinking structures of churches adopt the proper methods of admission passage in conformity to their terrain and the conditions of location. Hence forward such styles of church structures can be presupposed to be the main stream in building construction.

The use of critical pathways for a variety of clinical conditions has grown rapidly in recent years, particularly pathways for patients with acute myocardial infarction. We intend to determine the impact of a clinical pathway on ST-elevation myocardial infarction (STEMI) and to evaluate the efficacy and safety of facilitated percutaneous coronary intervention (PCI) compared with primary PCI. Low risk STEMI patients (ST elevation >0.1mV in more than 2 limb leads or ST elevation >0.2mV in contiguous precordial lead, chest pain lasting more than 30 min without response to nitroglycerin) will be included. All patients will be also treated medically according to critical pathway. STEMI is one of the common diseases in emergency medicine and so it is necessary to establish realistic treatment guidelines. The use of critical pathways will improve the quality of care.
