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.

As a nursing practice involves nurses' actions in a specific context of health care, this study has focused on exploring the espoused theories in nursing practice within the action science perspectives, Espoused theories are the belief, principles, and rationale expressed by the practitioner as guiding her/his actions in a situation of practice. The data were analysed qualitatively and 25 elements of espoused theories of nursing action were identified and clustered into 6 categories. The 25 elements of espoused theories are as follows: The clinical nurse worked in wholistic and individual nursing, focussed on the patient's needed, comfort and supportive nursing (5 theories of nursing goal) ; excellent skills, knowledge based, assessment and data collection, explaining, educating or a scientific basis(6 theories of nursing intervention): advocacy, value oriented, treatment, account- ability and commitment(4 theories of nursing ethics) ; human respect. partnership, trust(3 theories of patient-nurse relationship) : knowledgable, accumulated clinical experiences and personally lived experiences. positive perspectives(4 theories of nurse), role of intervention. rewarding peer relationship(3 theories of situations) The above mentioned espoused theories are similar to that of nursing textbooks which students learned through basic nursing education and almost the same as the Acts ofa Nurse in Korean. However, we are doubtful whether nurses actually do as they think. Therefore. it is recommended to review the theories-in-use in order to and any discrepancies between the espoused theories and the reality of nursing actions

Objectives : We aimed to evaluate the efficacy of biofeedback-assisted autogenic training for chronic tension-type headache, and to determine the relationship among the changes in electromyography (EMG) activity, headache activity, and mood states according to the psychophysiological treatment. Methods : Chronic tension-type headache patients aged from 20 to 40 years (n=35) were randomized to the treatment group receiving biofeedback-assisted autogenic training (8 sessions) or the monitoring-only control group. EMG activities, headache index, and various psychological variables were examined. Results : We found greater treatment response rate (≥50% reduction in headache index) in patients with biofeedback-assisted autogenic training than in the monitoring group (61% vs. 18% ; χ²=6.882, df=1, p=0.01). There were no significant changes in the mean values of the pretreatment EMG activities across the sessions m either group (all p’s>0.1). Mood states including anxiety and depression improved over time in the both groups, with the improvements being more prominent in the treatment group. Moreover, the reduction in depression level predicted treatment outcome in terms of headache index (95% confidence interval : 0.272-0.966, p=0.039). Conclusion : These results show that biofeedback-assisted autogenic training is effective for the treatment of chronic tension-type headache in a Korean population. Changes in mood states may be closely associated with the clinical outcome in the treatment of chronic tension-type headache using biofeedback-assisted autogenic training.

This study is aimed at offering basic data about prevention of Hepatitis B virus and infection control to dental hygiene students who will work mostly at dental offices which are characteristically exposed to a high risk of HBV infection. For this study, surveyed were 188 sophomores and juniors of the dental hygiene department who volunteered to undergo the tests of HBsAg and HBsAb. The examination of the blood collected from the samples and analysis of their perception about hygiene resulted in following conclusion: Positive HBsAg Four was found in 4 testees(2.1%) while 118(62.8%) revealed positive. HBsAb. Juniors showed higher positive rate in HBsAb whereas sophomores had higher positive rate in HBsAb. But such difference has statistically no significance. Generally, students seemed to pay little attention to HBV, judging from the survey of their perception about the present state of HBsAb and HBsAb(p>0.05), conduct of infection(p<0.05), completion of 3 requested vaccination(p>0.05), and formation of antibody(p>0.05). With regard to the infection routes of HBV, most students(92.4%) replied "through blood", which is statistically insignificant, though. Next ratio goes to the reply "through contaminated injectors". This reply came more from sophomores than from juniors, a difference which is statistically significant(p<0.05). The lowest rate of possible infection(29.2%) was thought to be "through breast-feeding of a positive mother"(p<0.05). In general, it turned out that sophomores had more knowledge about the infection routes of HBV than juniors. In terms of clinical history among family members, 6(3.1%) reported that some of their family members are currently suffering from a liver complaint, 3(1.6%) replied their family members were once afflicted, and 4(2.1%) said their members died of hepatitis. Except 10(4.7%), all the surveyees replied that their states of health are better than normal. Generally, sophomores are healthier than juniors except for very health case, a difference which is statistically of no value.

Recently the quality of life has enhanced and the personal originality revelation has been diversified. Accordingly the concern of beauty art has been increased. As a part of total fashion the make-up became more important because women who follow occupation have increased. In this thesis I analysed the modem pattern of make-up by the association rules technique using data mining, studying about the preference of color, darkness of skin color, Kohonen network grouping, the preference of color based on the color darkness. The preferred darkness of color of red, blue, pink, basic brown, others is classified by five level; very dark(o.91%, 2persons), a little dark(6.36%, 14persons), normal(33.91%, 64persons), a little mild(47.27%,104persons), very mild(11.62%, 26persons). The result of this study showed that university girls in Busan area prefer to make up with light tone and the preference order of make-up skin color was basic brown, blue, others, pink, red. In the major level of a little mild level the make-up color preference order was basic brown, blue, red, pink, others. For the cheek make-up, the color preference order was very mild(38.18%, 84persons), a little mild(29.09%, 64persons), normal(21.82%, 48persons), a little dark(3.64%, 8persons). University girls who prefer to make up a little mild preferred basic brown color and those who make up a little dark preferred blue. For the nail make-up, the color preference order was very mild(33.64%, 74persons), normal(25.24%, 56persons), a little mild( 19.09%.42persons), a little dark(9.09%, 20persons), very dark(2.73%, 6persons). University girls preferred to make up nails with very mild tone. According to the Kohonen network five preference group have been made and generally the girls changed their hair color. Specially group 2 and group 5 were the main groups. Recently the make-up pattern changed and the trend of make-up became deluxe. Therefore the necessity of make-up marketing database increased so much and using this pattern analysis, we can build a customer differentiation strategy and have a priority over the competitors.

We determined for IgE in serum based on the enzyme-linked immunosorbent assay(ELISA) in vivo after intraperitoneal injection of Solanum lyratum extract for 14 days. The experiment showed as well whole spleen cells that Solanum lyratum extract enhanced IgE production in vivo. Solanum lyratum extract significantly facilitated the production of IgE by LPS-stimulated murine spleen cells. Solanum lyratum THUNB. also enhanced IgE production from mouse whole spleen cells. Lypopolysaccharide(LPS) stimulated IgE production was enhanced 1.4-fold to 2.7-fold by the addition of Solanum lyratum extract over a period of 7 days.

The strength of concrete for design or core concrete for destructive test depends on several parameters including the size and type of specimen. The Korean and European Standard take 415x30 cylindrical and 15 an cubic specimens for measuring the concrete strength, respectively. There have been rare attempts to decide the relationships according to the shape and size of squared specimens. Especially. it is incorrect to use the existing data due to the different material properties in Cheju from the others. Therefore. in this experimental study, we investigate the relationships and compare with the existing results. The experimental results will be utilized to grasp the material and mechanical characteristics of concrete in Cheju.
