In this studying we could look that the rites for fortress under the rule of Silla's national rites was the one background which made Seonghwang religion in China was accepted in our nation. In Silla's national rites, fortress was the objects for rites and they were such as Bukhyeong fortress, Galim fortress, and Toseo fortress. These were belonged under Silla's national rites together with rites for famous mountains and big streams but differed from rites for mountains and streams. The fortresses which were belonged under Silla's national rites played a role as governing place during three nations era, but their prestigious position grew lower after provincial systems were consolidated. Fortress was the protectional building to protect the territory from the enemies. Silla's experiencing the war of three nations made them consider much the role of fortress as the important military location. And Silla included the rites for fortress into their national rites and governed the territory. The Galim fortress among them was got rid of Silla's national rites, and the rite seemed to be succeeded by provincial influentials. And this seemed to be the foundation for the provincial influentials in lateral Silla period to accept Seonghwang religion of China. And the fortress belonged to Silla's national rites was Kunhyeon fortress. Seonghwang-sa in Gorye was located in the fortress had governing place. Galim-fortress, Bukhyeong fortress, and Toseo fortress were also the important military locations. Seonghwang-sa in Gorye was the military strategic position, too and the deity for Seonghwang had the power to deal with the victory and defeat. From this, the background that the rite for Seonghwang in Gorye could be belonged to national rites comparatively early differed from China's was searched in the rites for fortress belonged to Silla's national rites.

The purpose of this study was to determine the effects of mother's education about amblyopia occlusion therapy on parenting stress and efficacy and the visual acuity improvement of the amblyopia child. The study was designed as a nonequivalent control group pretest posttest quasi-experimental study. The mothers with amblyopia children who signed the consent form were assigned to one of two groups, the experimental group (29) and control group (31). The data were collected from March 5 to October 5, 2010, at G university hospital outpatient department located in G city. The subjects in the experimental group participated in the Mothers Education about Amblyopia Occlusion Therapy for 24 weeks, which included face to face consultations, telephone counseling, etc.. The degree of parenting stress and efficacy were measured by using questionnaires and the visual acuity was measured by visual examination. The data were analyzed using the ${\chi}^2-test$, Fisher's exact probability test, t-test and Repeated Measure ANOVA using SPSS PC+20.0 for Windows. The following results were found after the therapy. The experimental group had statistically significantly higher visual acuity (Rt, F=40.64, p<.001, Lt, F=10.28, p<.001), lower parenting stress scores (F=9.85, p=.003) and higher parenting efficacy scores (F=22.19, p<.001) than the control group. In conclusion, the Mothers about Amblyopia. Occlusion Therapy Education Program was effective in improving the visual acuity of the amblyopia children, and decreasing the parenting stress and enhancing the parenting efficacy of their parents.

This study was carried out to improve cultivation techniques by low cost and labour saving in ginseng (Panax ginseng C. A. Meyer) seedling production, by elucidating proper ratio virgin soil and organic fertilizer, suitable height of front piller. The obtained results are as follows ; The optimal ratio of white decomposition of virgin soil and organic fertilizer was 10:1 for good yield of standard seedling, The fittest height of front piller was 150 cm because of both good seedling growth and yield. The cost for production of seedling of ginseng could be reduced by both optimal ratio of virgin soil, organic fertilizer and selection of front piller height.

As the needs of real-time visual object tracking are increasing in various kinds of application fields such as surveillance, entertainment, etc., kernel-based mean-shift tracking has received more interests. One of major issues in kernel-based mean-shift tracking is to be robust under partial or full occlusion status. This paper presents a real-time mean-shift tracking which is robust in partial occlusion by applying multi-mode local kernel weight. In the proposed method, a kernel is divided into multiple sub-kernels and each sub-kernel has a kernel weight to be determined according to the location of the sub-kernel. The experimental results show that the proposed method is more stable than the previous methods with multi-mode kernels in partial occlusion circumstance.

The purpose of this study was to investigate sole effect of therapy of spectacles correction on the refractive amblyopia. Spectacles were prescribed to give the same effect as the occlusion therapy undercorrecting in the case of hyperopia, and effectiveness of the therapy was compared with occlusion therapy without additional prescription. The results can be summarized as follows: 1. The higher anisometropic power was the lower initial visual acuity was. 2. Anisometropic power did not influence final visual acuity. 3. The latter beginning time of therapy was the higher astigmatism was. 4. Therapy of spectacles correction on the hyperopic amblyopia was quite effective.

This paper presents a marker image evaluation method based on analysis of object distribution in images and classification of images with repetitive patterns for effective marker-based augmented reality (AR) system development. We measure the variance of feature point coordinates to distinguish marker images that are vulnerable to occlusion, since object distribution affects object tracking performance according to partial occlusion in the images. Moreover, we propose a method to classify images suitable for object recognition and tracking based on the fact that the distributions of descriptor vectors among general images and repetitive-pattern images are significantly different. Comprehensive experiments for marker images confirm that the proposed marker image evaluation method distinguishes images vulnerable to occlusion and repetitive-pattern images very well. Furthermore, we suggest that scale-invariant feature transform (SIFT) is superior to speeded up robust features (SURF) in terms of object tracking in marker images. The proposed method provides users with suitability information for various images, and it helps AR systems to be realized more effectively.

To select optimal shade material in paddy soil, growth characteristics and ginsenoside contents were investigated in new cultivar, 'Cheonpoong' of three-year-old ginseng cultured under three kinds of shade materials such as three-layered blue and one-layered black PE (polyethylene) net (TBPN), blue PE sheet (BPSS), and aluminium-coated PE sheet (APSS). The order of light transmission ratio and air temperature by shade materials were BPSS > APSS > TBSB among three shade materials. Average soil water tension in PDC and IDC was 64 mbar (absolute soil moisture, 25%) and 123 mbar (absolute soil moisture, 17%), respectively, and soil water tension in IDC was changed more distinctly than that of PDC by season and shade materials. Yield in PDC was distinctly decreased more than that in IDC because of the increase of discolored-leaf and rusted-root ratio. BPSS and TBPN among three shade materials were the most effective on the increase of yield in PDC and IDC, respectively. Ratio of rusty-colored root showed not significant difference by drainage class and shade materials. Contents of panaxatriol ginsenoside (Rg1, Re and Rf) were decreased in PDC, while it of panaxadiol ginsenoside (Rb1, Rc and Rd) were increased in IDC. Total ginsenoside contents of IDC was distinctly higher than that of PDC, and BPSS showed the highest contents among three shade materials regardless of poorly and imperfectly drainage class.
