To investigate the flora of wetland at Mt. II-Kwang, the helophyte of the mountain was examined. The flora observed was classified into 2 phyla, 15 families, 27 genera, and 34 species. Representative species at the wetland were Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, Eriocaulon miquelianum, and Eleocharis attenuata var. laeviseta. In the lower part of the wetland, water was abundant and soil surface layer was thin, and Eriocaulon miquelianum-Carex canescens-Drosera rotundifolia, community were developed. On the other hand, in the upper part of the wetland, water was not abundant and soil surface layer was thick, and Agrostis clavata-Phragmiles japonica community were community were developed. Utricularia bifida and Utricularia yakusimensis were growing abundantly at this wetland, but Utricularia racemasa was few in number and narrow in the distribution area. Eriocaulon miquelianum, a Korean endemic plant, was observed, and Habenaria linearifolia, Spiranthes amoena, and Epipactis thunbergii, the CITES plant, were observed at this wetland. Insectivorous plant such as Drosera rotundifolia, Utricularia racemosa, Utricularia bifida, and Utricularia yakusimensis were also observed.

A weed population has been mainly analyzed through vegetative analysis method in ecology. However, this method is difficult to understand a detailed feature of weed dominance in terms of region and a particular weed species. Since GIS(Geographic Information System) tool has been introduced, this constraint was able to be solved. GIS analysis for the nationwide weed survey data in 1981 revealed that most predominant weed was Monochoria vaginalis and this species predominated mostly in a western part of Chungnam, a part of Kyunggi, a northern and southern part of Kyungbuk province of Korea. Eleocharis kuroguwai which was the most predominant weed species in 1992 was occurred at southern part of Kyunggi, central and western parts of Chungnam, and southern western part of Chumnam at the GIS analysis. GIS analysis was proven to give much more detailed information than vegetative analysis of weed population and this means that a data analysis by GIS would be used for operating a high effective control strategy against target weed species and site.

Cognitive-pragmatic language ability decreases during the normal aging process. Evaluating the ability might be useful in testing predicting cognitive level and diseases such as dementia. The aim of this study is to analyze various assessment protocols for normal aging, and evaluate the content validity of the currently developing cognitive-pragmatic language test domains and items. Content Validity Index(CVI) was calculated based on ratings judged by 17 experts including speech-language pathologists and clinical psychologists. As a result, it was found that CVIs of all 7 domains including attention, memory, organization, reasoning, problem solving, executive function, pragmatic language were above .75. It was concluded that the test items contained the appropriate content validity to assess cognitive-pragmatic language for normal aging.

The survey of weed occurrence was conducted to identify problem weed species in the paddy field. The 320 sites of the 13 regions in Gyeongbuk Province were investigated from June to July, 2013. In the whole region, 51 weed species were identified including 34 annuals and 17 perennials. The highest importance value of annual weed and perennial was dominant 88.4 and 48.7%, in Gumi region, respectively. The most dominant weed species in paddy fields of Gyeongbuk Province were Monochoria vaginalis var. plantaginea (10.80%), followed by Lemna paucicostata (10.74%), Bidens tripartite (8.77%), Echinochloa oryzoides (7.17%), and Scirpus juncoides (6.20%). The similarity of paddy weeds in 13 regions observed through TWINSPAN analysis was distinguished by Ludwigia prostrata, Scirpus juncoides, Lindernia dubia, Polygonum aviculare, and Alopecurus aequalis var. amurensis. The weed species, Ludwigia prostrata, was divided into the four regions, Gyeongju, Gumi(direct seeding cultivation), Youngcheon and Euiseong and ten regions, Gumi, Bonghwa, Sanju, Goryung, Youngdeog, Pohang, Sanju, Andong, Yecheon, and Cheongdo.

The allelopathic effects of rice and barley straws on lettuce germination and weed growth were investigated. The grinded straw of rice significantly inhibited lettuce germination. Both rice and barley straws decreased weed growth when they were used as a mulch in the field. Rice straw mulch applied with 500g/$m^2$ and 700g/$m^2$ decreased dry weight of Alopecurus aequalis more than 35%. Barley straw mulch applied with 200 g/$m^2$ inhibited dry weight of Echinochloa curs-galli and Digitaris sanguinalis, while the straw applied with 300 g/$m^2$ decreased those by 97%.

The spatial distribution of geographical distances at five natural populations of Camellia japonica in Busan, Korea was studied. The four plots (Mollundae, Gadeok-do, Du-do, and Jwiseum) of C. japonica were uniformly distributed in the forest community and only one plot (Amnam-dong) was aggregately distributed in the forest community. Morisita index is related to the patchiness index showed that the plot $20m{\times}50m$ had an overly steep slope when the area was larger than $20m{\times}20m$, which indicated that the degree of aggregation increased significantly with increasing quadrat sizes, while the patchiness indices did not change from the plot $5m{\times}10m$ to $10m{\times}10m$. The spatial structure was quantified by Moran's I, a coefficient of spatial autocorrelation. Ten of the significant values (76.9%) were positive, indicating similarity among individuals in the first 4 distance classes (80 m), i.e., pairs of individuals with dissimilarity characteristics can separate by more than 100 m.

The normal tissue in radiation therapy, to minimize radiation, it is most important to maximize local tumor control rates in intensive research the exact dose to the tumor sites. Therefore, the initial, therapist accuracy of detecting movement of the patient fatigue therapist has been a problem that is weighted down directly. Also, by using a web camera, a difference value between the image to be updated to the reference image is calculated, if the result exceeds the reference value, using the system for determining the motion has occurred. However, this system, it is not possible to quantitatively analyze the movement of the patient, the background is changed when moving the treatment bed in the co-therapeutic device was not able to sift the patient. In this paper, using a alpah(${\alpha}$) filter index is an attempt to solve these limitations points, quantifies the movement of the patient, by separating a background image of the patient and treatment environment, and movement of the patient during treatment It senses only, it was possible to reduce the problems due to patient movement.
