Sochi Heo Ryeon (1808 ~ 1893), who was born in Jindo in the late Joseon Dynasty, is a master of three classes, caligography, painting.It is a representative painter who is called the founder of the Honam Paintings. He learned Confucianism, Buddhism, Taoism from choui and learned the basics of painting.He became a student of Kim Chung Hee as an introduction of choui. Since then, I have correctly understood the painting aesthetic that realizes the painting by the paintings and paintings of chusa. And he succeeded it in the art world of Honam. His life and artistic features are the wandering that lasted over 70, many work activities, and details the records habit of details of "Sochisillok". Sochi's paintings aimed at Namjong painting, expressing the simple and clear beauty of the free brush and the landscape painting of ye-hwang style. In addition, the peony was painted with bizarre rocks, expressing the lively beauty by changing the brush to be called 'Heo-peony'. And it fulfilled the desire for riches and honors and the taste of Sunbee at the same time, and it became a representative material of 'Unlimsanbang' after being passed on to the house. His naturalized style of painting and painting aesthetic have been influential to the art world in modern Korea until now, forming a painter 's vein for 200 years over 5 generations.

Sochi Heo Ryun (小癡 許鍊, 1808-1893) was a literary artist of Chinese paintings of the Southern School during the late Joseon dynasty and the founder of paintings in the literary artist's style of Jindo County in South Jeolla Province. He was also a professional literary artist who acquired both learning and painting techniques under Choui (a Zen priest) and Kim Jeong-hee's teachings. Heo Ryun's landscape paintings were influenced by Kim Jung -hee. However, his ink orchid paintings, which he began producing in his later years, were not related to the 'Ink Orchid Paintings of Chusa (秋史蘭)'. His ink orchid paintings as a whole drew attention as he followed the old methods but still used rough brush strokes . Ordinary orchids were drawn based on Confucian content. However, his Jebal (題跋) and seal (印章) contain not only Confucian characters but also Taoist and Buddhist meanings. Therefore, it is possible to guess his direction of life and his private world of suffering. Ryun's ink orchid paintings reflected a variety of philosophies and aesthetic sensibilities. He went through a process of stylistic change over time and formed an 'Ink Orchid Painted Thought' in later life. The main characteristic of Sochi's ink orchid paintings is that he formed his own special methods for orchid paintings by mimicking the Manuals of Paintings. He drew orchids with his fingers in the beginning. Then, Jeongseop, Lee Ha-eung, Cho Hee-ryong, and others developed an organic relationship with the painting style of ink orchid paintings. Then in later years, orchid paintings reached the point of 'Picture Painted Thought (寫意畵)'. The above consideration shows that ink orchid paintings, which he produced until the end of his life, were the beginning of his mental vision and will to realize the image of a literal artist.

Present paper deals with the cost effective design of reinforced concrete building frame employing unified particle swarm optimization (UPSO). A building frame with G+8 stories have been adopted to demonstrate the effectiveness of the present algorithm. Effect of seismic loads and wind load have been considered as per Indian Standard (IS) 1893 (Part-I) and IS 875 (Part-III) respectively. Analysis of the frame has been carried out in STAAD Pro software.The design loads for all the beams and columns obtained from STAAD Pro have been given as input of the optimization algorithm. Next, cost optimization of all beams and columns have been carried out in MATLAB environment using UPSO, considering the safety and serviceability criteria mentioned in IS 456. Cost of formwork, concrete and reinforcement have been considered to calculate the total cost. Reinforcement of beams and columns has been calculated with consideration for curtailment and feasibility of laying the reinforcement bars during actual construction. The numerical analysis ensures the accuracy of the developed algorithm in providing the cost optimized design of RC building frame considering safety, serviceability and constructional feasibilities. Further, Monte Carlo simulations performed on the numerical results, proved the consistency and robustness of the developed algorithm. Thus, the present algorithm is capable of giving a cost effective design of RC building frame, which can be adopted directly in construction site without making any changes.

The VSA(Video Signal Analysis) method is the time-domain approach for estimating ultrasonic attenuation which utilizes the envelop signals from backscattered rf signals. The echogenicity of backscattered ultrasonic signals, however, from deeper depths are distorted when the broadband transmit pulse is used and it degrades the estimation accuracy of attenuation coefficients. We propose the modified VSA method using adaptive bandpass filters according to the centroid shift of echo signals as a pulse propagates. The technique of dual-reference diffraction compensation is also proposed to minimize the estimation errors because the difference of attenuation properties between the reference and sample aggravates the estimation accuracy when the differences are accumulated in deeper depth. The proposed techniques minimize the distortion of relative echogenicity and maximize the signal-to-noise ratio at the given depth. Simulation results for numerical tissue-mimicking phantoms show that the Rectangular-shaped filter with the appropriate center frequency exhibits the best estimation performance and the technique of the dual-reference diffraction compensation dramatically improves accuracy for the region after the beam focus.

The purpose of this study is to survey of Korean costume cultural assets in overseas museum collections. Cultural Assets represent the cultural heritage. Also costume is one of cultural assets. In 1980's the Korean government and scholars surveyed Korean cultural assets. One of their finding was that Korean objects exists some countries. Unesco delared that cultural assets illegally taken a way to foreign countries should be returned to their nations. However, few objects had been returned to korea. Today museum professional designing their exhibited and collections try to both enlighten experts and instruct and please amateur enthusiasts. Exhibitions are one of the most effective means of stimulating interest in cultural objects and ideas : they reflect prevailing cultural , intellectural and political trends. The 1893 Chicageo Exposition was the first international exhibition in which Korea has ever taken part. Overseas museum held many Asian exhibitions however Korean exhibitions have been held much less frequently than those of most other Asian countries. (China, and Japan). Some of Korean art Collection have historical and artistic valuable , most overseas museum' collection are of low value and non-informative . Several museums in United States that have Korean costume : some of these museums have highly valuable historical and contextural objects. It is my hope that the information in this paper will be of use for those interested in learning more about Korean culture.

We have redefined the $\alpha$ -parameter of the extended transmitters in the presence of self-phase modulation (SPM) induced chirp. The $\alpha$ -parameter is effectively lowered to about 1, when the SPM effect with the launching power of 12.5dBm (maximum launching power to avoid stimulated Brillouin scattering(SBS)) is included, compared to the $\alpha$ -parameter of the transmitter algone. The lowered $\alpha$ -parameter has improved the transmission performance significantly regardless the transmitter is operated with positive or negative chirp. The SPM-induced effective $\alpha$ -parameter can be used as a design parameter for the high speed (10 Gbps) transmission systems.

Laterite blocks are used for construction of masonry walls since ages in the South-western coastal areas of India. The south-west coastal areas of India lie in zone III of seismic zonation map of Indian code IS 1893-2002. In spite of the fact that laterite is the most favored masonry material in these regions of India, the structural performance of laterite masonry has not been systematically investigated. Again there are no previous studies addressing, in detail, the seismic performance of laterite masonry buildings. Now that these areas are becoming more and more important from point of view of trade and commerce, there is a need for a detailed research on the seismic response of laterite masonry structures located in these areas. The present paper reports the results of such a study of the seismic response of box-type laterite masonry structures. Time history analysis of these structures under El-Centro acceleration has been performed using commercial finite element software ANSYS. Effect of 'containment reinforcement' on the seismic response of box type laterite masonry structures has been evaluated.

The total polyphenol contents and antioxidative activities of water and ethanol extracts from Synurus excelsus and Synurus palmatopinnatifidus var. palmatopinnatifidus were determined. Total polyphenol contents of ESE and ESP were 195.7 and 216.2 mg/g, and were higher than WSE (74.7 mg/g) and WSP (77.4 mg/g). The total flavonoid contents were also higher in ESE (176.6 mg/g) and ESP (148.8 mg/g) than WSE and WSP. DPPH radical scavenging activities of ESE and ESP (73.1 and 73.4%) were higher than WSE and WSP as like total polyphenol and flavonoid contents. Although the DPPH radical scavenging activities of the extracts were proportional to total polyphenol contents, there are no differences between water extracts and ethanol extracts of Synurus excelsus and Synurus palmatopinnatifidus on ABTS radical scavenging activities. Moreover, all the solvent extracts (ESE, ESP, WSE and WSP) had no SOD-like activity. These results suggest that consideration for adoption of method is necessary to evaluate antioxidative activity of extracts from plants including vegetables.

According to the cognitive science research, the interaction intent of humans can be estimated through an analysis of the representing behaviors. This paper proposes a novel methodology for reliable intention analysis of humans by applying this approach. To identify the intention, 8 behavioral features are extracted from the 4 characteristics in human-human interaction and we outline a set of core components for nonverbal behavior of humans. These nonverbal behaviors are associated with various recognition modules including multimodal sensors which have each modality with localizing sound source of the speaker in the audition part, recognizing frontal face and facial expression in the vision part, and estimating human trajectories, body pose and leaning, and hand gesture in the spatial part. As a post-processing step, temporal confidential reasoning is utilized to improve the recognition performance and integrated human model is utilized to quantitatively classify the intention from multi-dimensional cues by applying the weight factor. Thus, interactive robots can make informed engagement decision to effectively interact with multiple persons. Experimental results show that the proposed scheme works successfully between human users and a robot in human-robot interaction.
