Purpose: This study aimed to identify how an education program on palliative care affects nursing home caregivers' perception of hospice care and attitude towards terminally ill patient care. Methods: This study was conducted using a nonequivalent control group with a pretest-posttest design. The participants were 101 certified care workers: 58 in the experimental group and 43 in the control. The experimental group completed the palliative care education program consisted of 20 hours of classroom training and 20 hours of clinical practicum. An ANCOVA was performed to compare the score changes to outcome variables. Results: Compared with the control group, the experimental group showed significant pretest-posttest differences in both the perception of hospice care (F=21.09, P<0.001) and attitude towards caring for terminally ill patients (F=13.28, P<0.001). Conclusion: These results indicate that the palliative care education program for caregivers is effective in preparing participants to provide hospice/palliative care service. Further study is warranted to explore the effects of this program on palliative caregivers' performance.

The purpose of this study was to investigate the effect of computer based cognitive rehabilitation program on the generative naming. Twenty - one patients were assigned to the CoTras program and eight were treated with traditional face - to - face language rehabilitation such as paper and table activities. The experimental group and the control group performed sequential language recall memory training, association memory recall training, language categorization memory training, and language integrated memory training for 12 weeks. The Welch's robust ANCOVA showed significant differences in mean fluency and MMSE-K changes (p<0.05). On the other hand, phonemic fluency increased significantly after 12 weeks of treatment compared to baseline in both experimental and control groups, but there was no statistically significant difference between treatment groups. The results of this study suggest that the computer based cognitive rehabilitation program may be more effective in improving the semantic fluency than the conventional cognitive-linguistic rehabilitation.

Effect of dietary inclusion of various sources of green tea on growth, immune system and challenging test of juvenile olive flounder Paralichthys olivaceus was investigated. Five experimental diets with triplicates were prepared: control, raw leaves, dry leaves, by-product and extract. Twenty five (an initial body weight of 52.5 g) were randomly distributed into 15 of 180 L flow-through tanks. Nutrient requirements of the experimental diets satisfied growth of juvenile olive flounder. The feeding trial lasted for 7 weeks. After 7-week feeding trial, blood were sampled from three randomly chosen fish for serum analysis of Iysozyme and bactericidal activity, and ten fish were infected with Edwardsiella tarda for challenging test from each tank. Weight gain (g/fish) of fish fed the diet containing extract and control diet was significantly higher than that of fish fed the other diets. Feed efficiency ratio for fish fed the diet containing extract and control diet was significantly higher than that for fish fed the diets containing raw leaves and by-product, but not significantly different from that for fish fed the diet containing dry leaves. Serum Iysozyme activity (units/ml) of fish fed the diets containing dry leaves and extract was significantly higher than that of fish fed the diets containing raw leaves and by-product, but not significantly different from that of fish fed the control diet. Serum bactericidal activity (${\times}10^6$ bacteria/ml) of fish fed the diet containing dry leaves and extract was significantly lower than that of fish fed the diets containing raw leaves, by-product and control diet in 3 hour. However, serum bactericidal activity of fish fed the diet containing extract was significantly lower than that of fish fed the other diets in 6 hour. And serum bacterial activity was low in fish fed the diets containing dry and raw leaves, by-product, and control in 6 hour in order. Accumulative mortality (%) of fish fed the control diet was low compared to that of fish fed the diets containing raw leaves and by-product, but high compared to that of fish fed the diets containing dry leaves and extract although no significant difference was found among treatments. In considering above results, dietary inclusion of extract and dry leaves of green tea seemed to be highly effective to improve immune system and endurance against E. tarda infection of juvenile olive flounder.

The study was conducted to find effect of irrigation treatment during growth stage on growth and yield of Paeonia lactiflora Pallas L.. In case of top ground part, growth of irrigation treatment at early growing stage(from May 1 to June 12) was larger(stem length of 79.4cm) or thicker(stem diameter of 6.5mm) than stem length of 13.6∼7.4cm and stem diameter of 0.5mm of natural plot and control. The growth of under ground part, root length(34.0cm) and number of root/plant(43.6ea/plant) in irrigation treatment at early growing stage were relatively larger or more number than that of control, and root yield was gained 2,349kg/10a and increased 13% and 8% compare with natural plot and control, respectively. Commercial ratio of root was higher for irrigation treatment at early growing stage, it was increased by 20% than 1,708kg/10a of natural plot.

This study analyzed the change of physical and chemical characteristics on the safflower seed produce coated edible film. L and a value of safflower seed product coated edible film were slowly increased during storage, while b value decreased. Moisture content were increased during storage. Acid valus welt less increased when edible film was ased. Peroxide values were also increased during storage, but peroxide value in products coated sodium caseinate or k-carraggenan was $50\%$ in the control after 30 days of storage. The value of sensual test was higher in products coated sodium caseinate or k-carraggenan than those of control. Coating with sodium caseinate or k-carraggenan was effective for acidification retardation and quality improvement of safflower seed products.

To establish the mass propagation method of Typha orientatis Presl, several factors influencing seed germination were investigated. The best seed germination of T. orientalis was achieved under the light and 25~3$0^{\circ}C$ temperature. GA$_3$ tended to enhance seed germination, and 500 mg.L$^{-1}$ GA$_3$ showed 90.7% germination, which was 1.2 times of control. Compared to control, BA treatment prohibit seed germination. Especially, seeds were not germinated under 500 mg.L$^{-1}$ BA treatment. In case of KNO$_3$ and Ca(NO$_3$)$_2$ treatment, the germination rate was decreased by all concentrations, except 100 mM Ca(NO$_3$)$_2$.

Recently, Plasma Display Panel(PDP) has been in the spotlight as one of the next generation flat-panel-display device. However, it has several drawbacks like the low contrast ratio and the low luminance. In this study, a new address waveform is suggested to improve the priming effect and contrast ratio at the address period in the Address Display period Separated(ADS) method. We modified waveform, instead of a conventional waveform, to an address period, for operating on the Plasma Display Panels, which used the conventional gas [He-Ne-Xe〕. When the ramp pulse is added to the address period at the sustain electrode, it is improved on the priming effect and contrast ratio.

1. 도체특성 대조구와 비교하여 생봉독 1처리구와 2처리구의 경우 암퇘지와 거세돼지 모두에서 도체중, 도체율이 증가하였으며, 등지방두께도 두꺼워졌다. 이러한 도체특성은 도체등급을 향상시켜 A와 B등급 출현율이 높아져 경제적으로 유리한 것으로 사료되었다. 2. 육질특성과 PSE육 발생율 대조구와 비교하여 생봉독 1처리구와 2처리구의 경우 암퇘지와 거세돼지 모두에서 등심육의 일반성분중 지방함량이 높은 수준을 나타내었고, pH와 보수력이 높고, 육즙손실과 가열감량이 낮아 우수한 육질특성을 나타냈다. 그 외 주관적 판정의 마블링 점수가 높았고, 육색측정에서도 진한 적색을 나타내어 우수한 외관을 보여주었다. PSE육 발생율에서는 암퇘지와 거세돼지 모두에서 무처리구에 비해 3개 생봉독처리구에서 발생율이 감소했는데, 특히 생봉독2처리구가 낮았다.

This paper describes the design principles and methods of electronic processor for thermal imager with 320$\times$240 staring array infrared detector. For the detector's nonuniformity correction and excellent image quality, we have designed the multi-point correction method using the defocusing technique of the optics. And to enhance the image of low contrast and improve the detection capability, the new technique of histogram processing has been designed. Through these image processing techniques, we have developed the high quality thermal imager and acquired a satisfactory thermal image. The result of MRTD(Minimum Resolvable Temperature Difference) is $0.1^{\circ}C$ at 4cycles/mard.
