Ginseng (Panax ginseng C.A. Meyer), one of the most widely used medicinal plants in traditional oriental medicine, is used for the treatment of various diseases. It has been classified according to its cultivation environment, such as field cultivated ginseng (FCG) and mountain cultivated ginseng (MCG). However, little is known about differences in gene expression in ginseng roots between field cultivated and mountain cultivated ginseng. In order to investigate the whole transcriptome landscape of ginseng, we employed High-Throughput sequencing technologies using the Illumina HiSeqTM2500 system, and generated a large amount of sequenced transcriptome from ginseng roots. Approximately 77 million and 87 million high-quality reads were produced in the FCG and MCG roots transcriptome analyses, respectively, and we obtained 256,032 assembled unigenes with an average length of 1,171 bp by de novo assembly methods. Functional annotations of the unigenes were performed using sequence similarity comparisons against the following databases: the non-redundant nucleotide database, the InterPro domains database, the Gene Ontology Consortium database, and the Kyoto Encyclopedia of Genes and Genomes pathway database. A total of 4,207 unigenes were assigned to specific metabolic pathways, and all of the known enzymes involved in starch and sucrose metabolism pathways were also identified in the KEGG library. This study indicated that alpha-glucan phosphorylase 1, putative pectinesterase/pectinesterase inhibitor 17, beta-amylase, and alpha-glucan phosphorylase isozyme H might be important factors involved in starch and sucrose metabolism between FCG and MCG in different environments.

Using the principal component analysis and clustering Forest resources are consistently necessary in the future. It takes much time to produce and breed them. However it is difficult to do due to recent social situation. Considering global environment, forest policy should be considered as a global scale rather than a regional one. At least, the policy needs a national scale concern. In order to support forestry, elementary data are needed. In this study, forest characteristics in Ishigawa-gen province have been analyzed through main component analysis and clustering. The results are shown in fig.5 and fig.6.

This study intended to analyze the spatial distribution of two types of weeding song (Short Bang-a and Sangsa ryu) and how geomorphic elements influence the propagation of the songs in Chungcheongbuk-do area. The distribution of the two types of song was mapped as point data. According to the result, both types showed similar distribution pattern. In order to figure out the reason of this similarity, the distribution pattern of songs was analyzed at various scales based on geomorphic elements including river, mountain and lineament. The result showed that most of distribution pattern of songs followed the lineament direction. Also, the spatial continuity among mountain that was formed by large and small lineament in various directions could be the path of the cultural diffusion. If the lineament with same direction does not intersect other lineament that have different direction, spatial continuity would be blocked. Consequently it was confirmed that propagation of songs has not spread smoothly.

Compressive strength is one of the most important engineering properties of concrete, and testing of the compressive strength of concrete specimens is often costly and time consuming. In order to provide the time for concrete form removal, re-shoring to slab, project scheduling and quality control, it is necessary to predict the concrete strength based upon the early strength data. However, concrete compressive strength is affected by many factors, such as quality of raw materials, water cement ratio, ratio of fine aggregate to coarse aggregate, age of concrete, compaction of concrete, temperature, relative humidity and curing of concrete. The concrete compressive strength is a quite nonlinear function that changes depend on the materials used in the concrete and the time. This paper presents an adaptive neuro-fuzzy inference system (ANFIS) for the prediction of concrete compressive strength. The training of fuzzy system was performed by a hybrid method of gradient descent method and least squares algorithm, and the subtractive clustering algorithm (SCA) was utilized for optimizing the number of fuzzy rules. Experimental data on concrete compressive strength in the literature were used to validate and evaluate the performance of the proposed ANFIS model. Further, predictions from three models (the back propagation neural network model, the statistics model, and the ANFIS model) were compared with the experimental data. The results show that the proposed ANFIS model is a feasible, efficient, and accurate tool for predicting the concrete compressive strength.

In this research, we study a modified relaxed Tseng method with a single projection approach for solving common solution to a fixed point problem involving finite family of τ-demimetric operators and a quasi-monotone variational inequalities in real Hilbert spaces with alternating inertial extrapolation steps and adaptive non-monotonic step sizes. Under some appropriate conditions that are imposed on the parameters, the weak and linear convergence results of the proposed iterative scheme are established. Furthermore, we present some numerical examples and application of our proposed methods in comparison with other existing iterative methods. In order to show the practical applicability of our method to real word problems, we show that our algorithm has better restoration efficiency than many well known methods in image restoration problem. Our proposed iterative method generalizes and extends many existing methods in the literature.

고성군에 위치한 폐구리광산의 중금속 오염범위와 정도 및 환경위해성을 평가하기 위하여 광산지역으로부터 토양과 벼를 채취하여 중금속 함량을 분석하였다. 중금속 함량은 논토양에 비해 산토양에서 훨씬 높았다. 중금속 전함량은 산토양에서 Cu>Zn>Pb>As>Cr>Cd, 논토양에서 Zn>Pb>Cu>Cr>As>Cd 순으로 감소하였으며, 0.1/1N HCl에 의한 중금속 용출량은 산토양에서 Cu>Pb>Zn>As>Cd>Cr, 논토양에서 Pb>Cu>Zn>As>Cd>Cr 순으로 나타났다. 중금속 용출비는 시료채취지점에 따라 매우 다양하였지만 평균적으로는 Cd(16%)>Pb(10%)>Cu(9%)>As(4.5%)>Zn-Cr(${\le}2.5%$)의 순이었다. 조사대상 토양들은 지각평균값에 비해 중금속이 부화되어 있으며 그 순서는 $As{\ge}Cd>Pb>Zn>Cu>Cr$이었다. 토양의 중금속 전함량 또는 용출량으로부터 계산한 오염지수는 중금속 오염이 폐구리광산 특히 삼산제일광산 주변의 산토양에 국한되어 있음을 나타내었다. 현미 중의 중금속함량은 As $nd{\sim}0.87mg/kg,\;Cd\;0.02{\sim}0.34mg/kg,\;Cu\;1.01{\sim}6.25mg/kg,\;Mn\;13.4{\sim}43.2mg/kg,\;Pb\;0.09{\sim}2.83mg/kg$ 및 $Zn\;16.5{\sim}79.1mg/kg$으로 심각하게 오염된 수준은 아니었다. 토양 pH와 함께 중금속의 용출 및 분포특성들은 이 지역 중금속 오염의 대부분이 중금속의 용해 순환보다는 폐광석과 맥석광물의 쇄설성 이동에 의해 진행되고 있음을 시사하였다.

The site for this plan is located at the foot of Mt. Unseo at Galcheon-ri, Changsu-myon, Youngdeok-gun. On the site stands Jangyutsa Temple, built by priest Naong in 1355 (in the 4th year of King Gongmin during Koryo Kingdom). The purpose of this plan is to widely publicize and commemorate priest Naong by designing a district centering around the temple. The basic directions of design can be summarized as follows 1) A special Buddhists'pilgrimage and sight-seeing district aimed at commemorating priest Naong will be developed to preserve the historic figure of priest Naong. To this end, a facility will be built to collect, preserve and exhibit materials related with the great priest in order to preserve his legacy and enhance the image of the space. 2) Special fractions which are rare in other districts will be introduced to create an image different from the conventional memorial districts or sight-seeing zones. To this end, the district will be divided into the Jangyuksa Temple area proper and a district memorial area, each of which will have its own unique characteristics with different functions. On the other hand, the two different areas will be related with each other and complemented by each other. Such planning techniques as articulation and superimposition will be used for a synergistic effect. 3) The plan will accommodate various programs centering around historical and cultural assets, and at the same time will allow tourists to have various experiences and access to the natural environment as well as to a variety of events. 4) In order to plan such landscapes as shown in the traditional mountain temples, the traditional tectonic forms will be used for the facilities. It is expected that the district surrounding Jangyuksa Temple will become a popular sight-seeing destination, and with new historical and cultural environments will become a valuable resource to widely publicize the culture of Youngdeok-gun.

The ten traditional symbols of longevity are represented as 10 which means perfection in oriental philosophy, the sun, mountain, water, cloud, rock, pine tree, elixir plant, tortoise, crane and deer. each subjects symbolizing longevity had used in isolation. unlike China and Japan, the ten symbols of longevity became a fixed form and was widely used in paintings, household effects and clothes in Korea. therefore, It will be a meaningful study how the ten symbols of longevity, as one of subjects in painting, changed into a pattern on clothes. The ten symbols of longevity was affected by various philosophies and religion. especially, it laid emphasis on order by Yin-Yang and the Five Elements theory. the order was applied to arrange each subjects and use colors carefully. the sun colored with red and was on the upper. the pine tree colored with green meaned tree and was on the left. the earth and the mountain meaned the soil and was on the center. the rock meaned the iron and was on the right. the water meaned the water and was on the bottom. The subjects of the study were embroideries like spectacle cases, spoon cases and pouches. the scope of study was the Latter Part of the Joseon Dynasty because there are more relics in the Joseon Dynasty than any other times.

백두대간이란 개념은 신라말엽-고려 초기에 잉태되어 고려시대를 거치면서 성장하였고, 조선시대에 와서 완성되었다. 이런 백두대간 개념을 오늘에 복원하기 위해서는 첫째, 백두대간은 마루금이 아니라 영역의 개념이며, 둘째, 백두대간은 산마루의 모임이 아니라 수계(水系)와 산계(山系)의 결합체라는 사실을 인식해야 한다. 백두대간 관리범위를 설정할 때에는 전통사상에 입각하여 기준을 잡고, 자연환경을 감안하여 이들을 포괄할 수 있도록 해야 할 것이다. 이렇게 설정된 관리범위는 3차 수계까지 포함하는 것으로 나타났는데 보전지역은 최소한 1차 수계는 포함해야 할 것이며, 백두대간 관리방안에서 가장 중요한 것은 지형훼손을 방지하는 것이다. 백두대간은 우리나라를 세계만방에 알리는 이름인 Korea, 즉 고려(高麗)정신을 대표하므로 이를 잘 관리하는 것은 남북통일의 초석을 놓는 일이기도 하다.
