The series of forest Fires in Kangwon Province in April, 2000, were one of the mast serious ones in the Kang-won Province in recent years. The fire damaged areas are extensive and this paper investigates the utility of the satellite image data, particularly the RADARSAT SAR data. One of the main objectives of this study included evaluation of potential usefulness of the C-band RADARSAT data in the detection of forest fires in mountainous areas. Among several fire damaged sites, the area near Samchuk (city) was selected as the main study area and mufti-temporal RADARSAT(raw) data were acquired and the processed results were comparatively investigated with the IRS-1c data acquired shortly after the fire. To identify the burnt area from the undamaged background in the optical imagery, supervised classification and NDVI processing were carried out and tested with the IRS-1C data. For this experiment, several sets of raw RADARSAT standard and Fine mode (S4, F3, ascending orbit) data were processed and the final image was formed. In addition to the final image, sigma nought (σ°) was catnputed and compared for the burnt area against the undamaged areas. Because of the steep slopes in the study area and subsequent deviation from the flat surface scattering models, the fire scars in the sigma nought (σ°) image were not apparent. However, fire scars are slightly detected in the difference and ratio images obtained from the signal intensity data acquired at different dates (bath before and after fire). Texture analysis of the image data including the burnt areas were carried out using the Multiplicative Markov Random-Field (MMRF) algorithm. The detection of the fire damaged area from both standard mode and fine mode RADARSAT was not as straightforward as in optical data. However, Previous studies with ERS-1 S_AR and RADARSAT data in Indonesia and in the North American Plains indicate that C-band SAR data provide us with an effective tool for studying the forest fire damages. However, the application of C-band SAR data to the analysis of the forest fire areas requires careful processing of the data with realistic scattering models.

Kang,Minyeong(Minyeong Kang),Kim,Eun Young(Eun Young Kim),Chang,Sung Ok(Sung Ok Chang) 한국노인간호학회 2022 노인간호학회지 Vol.24 No.4

Purpose: This is an analysis of the experiences of nurses in Post Anesthesia Care Units (PACUs) in caring for older patients with emergence delirium using the Q-methodology. Methods: The Q-methodology, which is used to explore and understand human subjectivity, was applied. Thirty nurses who had experiences in providing nursing for delirium in older patients after surgery in a PACU participated in this study. Results: This study revealed three factors regarding the frame of reference of PACU nurses in detecting and managing older patients' emergence delirium: “detect the deviant changes leading to instability”, “focus on the patient’s degree of cognitive recovery within the framework of recovery time”, and “awareness of possible clues based on the patient’s underlying disease(s)”. Conclusion: These findings are expected to be utilized as a basis for more practical and accessible PACU nurse delirium education that reflects nurses’ subjective viewpoints explained by the three identified factors.

All of them were educated about Spiritual Nursing Care for 100 minutes in a week, during totally 8 weeks in one semester. The data were collected during 7days from July 11 to July 18,2004 by using structured questionnaire method. The measurement of the spiritual well-being was performed with 6 points-index which is composed of 21 items and is modified by Sang-Soon Choi(1990)from Palau tzian & Ellison(1983) s. Its high score means that the degree of spiritual well-being of the subject is high. The data were analyzed by using the SPSS WIN 10.1 program according to the purpose of this study. The general characteristics of the subjects were analyzed by calculating the real quantity and the percentage, and the spiritual well-being scores were identified through calculating the mean value of individual domain. The significant difference of the general characteristics with the spiritual well-being was analyzed by t-test and ANOVA, Scheffe s test. The results of this study were as follow; 1.The spiritual well-being of the subjects The average value for the spiritual well-being of the subjects was 97.78(SD=±10.53) among the possible ranges of 21-126. The mean value of all items was 4.66(SD=±0.502) and high relatively. 2. The spiritual well-being according to general characteristics of subjects The analysis of the spiritual well-being according to general characteristics of the subjects showed statistically significant difference on the degree of life satisfaction in faith(F=4.327, P= .004),the degree of recognition about God s initiation in their daily life(F=3.933, P= .013),the degree of satisfaction about Nursing as their major(F=6.608, P= .000), their assurance of salvation(t=4.557,P= .037). among the personal religious actions, praising(F=3.32,p= .017), The group of nursing students responded that they were satisfied in their faith life, always God has the initiative in their daily lives personally, they were satisfied about Nursing as their major very much, and they have their assurance of salvation showed the highest degree of the spiritual well-being than any other group. In conclusion, in this study we observed that the spiritual well-being of nursing students was high relatively. The general characteristics of subjects were related to the spiritual well-being of them were the degree of satisfaction in their faith lives,their recognition about God s initiation in their daily life, their satisfaction about Nursing as their major, among the personal religious actions, regular praising and their assurance of salvation. Therefore this study s results can be used for developing a spiritual nursing education and program to strengthen nursing student s spirituality to practice in spiritual nursing care.

Fracture healing is a complex physiological process that involves the coordinated participation of several cell types. Unlike other tissues that heal by the formation of poorly organized scar, in fracture healing the original tissue, bone, is regenerated and the properties of the preexisting tissue largely are restored. Fracture healing generally proceeds in an orderly fashion when appropriate biological and mechanical component are present. Many complications may occur with repair and subsequent healing of fracture, including osteomyelitis, implant loosening, and fracture instability. All of these complications may result in delayed union, nonunion or malunion of the fracture. A 1-year-old male, Collie sustained a closed, transverse femoral fracture in a mortor vehicle accident. His initial treatment with open reduction and bone plating was failed. A second surgery was done to remove the plate and perform corrective osteotomy, and bone grafting. Histopathological observation of the bone fragment from fracture end was carried.

This study investigates the effects of environmental prints on vocabulary learning of Korean Elementary School English language learners and their perspectives on vocabulary learning. The participants were 107 elementary school students in Kyunggi province, and they were divided into two groups. The students in both groups participated in vocabulary learning activities based on different materials, which were environmental prints and photos, respectively. The results of the post-test and delayed post-test showed that the students in the environmental prints group learned significantly more vocabulary items than the students in the photos group. The analyses of the students’ responses to the questionnaire revealed that the environmental print group had shown significant progress in interests and confidence in vocabulary learning. The results also showed that the students believed that they may be able to use the target words in their lives, indicating that environmental prints enhanced the situational authenticity of vocabulary instruction. These results suggest that environmental prints are useful instructional materials for vocabulary teaching in elementary school English instruction. 본 연구의 목적은 환경 인쇄물을 활용한 어휘 학습 활동이 초등학교 영어 학습자의 어휘 학습 결과와 어휘 학습에 대한 태도에 미치는 영향을 알아보는 데 있다. 환경 인쇄물은 학습자가 실생활에서 쉽게 접할 수 있고 목표 어휘에 대한 맥락을 제공하며 학습자의 학습동기를 높일 수 있어서 모국어 교육에서는 많이 활용되지만 제2 언어 어휘 교육에서는 상대적으로 많이 활용되지 않고 있는 실정이다. 본 연구는 환경 인쇄물이 영어를 외국어로 배우는 환경에서 초등학교 어휘 학습에 유용한 교수 자료인지 알아보고자 한다. 이를 위하여 본 연구에서는 초등학교 6학년 학습자를 대상으로 초등학교 어휘 교수에서 많이 사용되고 있는 사진 자료를 사용해서 어휘를 학습한 집단과 환경 인쇄물을 활용한 어휘 학습 집단으로 나누어 총 60개의 어휘를 교수한 후 학습 결과와 학습자의 정의적 태도를 비교하였다. 연구 결과 환경 인쇄물을 활용한 집단이 사진을 활용하여 어휘를 학습한 집단보다 통계적으로 유의미한 수준에서 어휘를 더 많이 학습한 것으로 나타났다. 어휘 학습에 대한 흥미와 자신감, 그리고 어휘 학습의 중요성에 대한 학습자의 반응을 비교한 결과 자신감 영역에서 환경 인쇄물 집단의 점수가 사진 집단의 점수보다 더 높았다.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.
