RHS is a core organization with huge influences on the expansion of the base for the garden culture and industry. This study aimed to examine the meaning and value of the professional charity's role through the appearance background and developmental process of RHS. The passion for plant collection in the Victorian Age of the $19^{th}$ century became the background of establishing the society. Such background of the times and the root of the society are deeply related to the British civil garden culture. The consideration of the forming process of RHS and the study can be summarized as below. First, the professional introduction of exotic plants by plant hunters was developed into an organization supporting professional plant research through collection, sampling, and records, which led to the development of horticulture techniques, growth of plant nursery businesses and established the foundation of the civil garden culture in the UK. Second, after John Loudon was involved in RHS, inspired by the press editing more practical information contents, middle-class and women became new patrons to gardening. Therefore, the care of gardens became a source of agreeable domestic recreation, especially to the female sex. Third, $19^{th}$ century plant collection and exhibition was seen in the Chelsea Flower Show which a key role beyond the UK garden culture. Fourth, those acts of RHS and modernity in $19^{th}$ developed British middle-class domestic gardens which have the character of the ordinary and national garden style in the UK. Such history and activities of RHS are connected to the national status as a country of gardens, which suggests clues to practical measures and values we should aim for in order to settle citizen-centered garden culture.

Environment-friendly agriculture (EFA) are aimed to reduce use of chemical inputs as possible the recycling of resources and the environment while preserving the local resources in the long term to ensure a constant productivity and profitability for producing safe food. This study was conducted to investigate characteristics on soil environment at paddy field of environment-friendly agriculture regions (EFARs) in Honam area. Survey point of EFARs Chungnam, Jeonbuk and Jeonnam, rice bran farming method in two districts, rice bran + snail farming method in eight districts, snail farming method in five districts and ducks farming method in three districts a total of 18 districts were selected. Annual of farming method, friendly-environment certification, amount of applied fertilizer, and history of cultivation to the farm household were surveyed. The content of available phosphate and silicate among the soil chemical properties in EFA paddy field were a little lower than optimum level, and those of agricultural methods fertilized with rice bran were a little lower than those of others. Hardness among the soil physical properties in EFA paddy field were a little lower than conventional practices, and that of agricultural methods fertilized with rice bran were a little lower than those of others. We showed fertilizer recommendation dose about soil nutritional shortages according to fertilization prescriptions index by crops.

Buddhist stupas, which are a symbolic architecture of Buddhism and enshrine the Jinsinsari of Buddha, were reinvented as stone stupas appropriate for the natural soil of Korea from existing wooden stupas around the 7th century after the introduction of Buddhism. Later, the construction of a stone stupa was expanded to local areas from the central area around the 9th century; thus, stone stupas of more diverse local colors were built in a nationwide scale, and today it is called a "country of stone stupas". While focusing on the stylistic interchanges between stone stupas, which were established in each region in accordance with the localization of the establishment of stone stupas that was begun actively from the 9th century, this paper selected several cases of stone stupas among about 50 stone stupas in the Gangwondo-region. First, the study compared the stone stupas and Buddhist priest tower of Seollimwonji, Jinjeonsaji, and Geodonsaji, which are located at the same temple site as the current Buddhist priest tower, from among typical Silla style stupas that match the 9 stone stupas in the Gangwon-do region. This is because stylistic interchanges were possible while there were mutually organic relationships between Buddhist statues such as stone stupas, Buddhist priest towers, stone lanterns, and Buddhist pedestals, which used the same stone material along with the expansion of Buddhism to local areas in accordance with the spread of Zen Buddhism in the 9th century. Second, a comparison was made of the stylistic similarities between the Woljeongsa Palgakgucheong (eight sides nine-storied) stone stupa and the Sinboksaji Samcheung (three-storied) stone stupa, which are totally different in regard to the number of stories and the flat form. These two stone stupas are representative Goryeo stone stupas. The Woljeongsa stone stupa is a Goguryeo-oriented stone stupa with many sided multiple stories whereas the Sinboksaji stone stupa has been known as an early case of the insertion of the support of Tapsin in each story. Although the two stone stupas may look very different, but through close investigation it was confirmed that there were many stylistic interchanges between them and not only the seated stone Buddha statue in the cylinder jewel case in front of the stupa but also the stone stupa established by the same master. Consequently, this paper aimed not merely to mention the simple patterns of stone stupas, but, further, to trace the interchange in patterns in accordance with the construction period based on those patterns.

This research is a quest of theories of poetry of Wang Yak-heo who was a literary critic during Chin(金) dynasty in ancient China. Wang Yak-heo left a fine piece of work, dubbed ${\ll}$Honam Yuro Jib${\gg}$ and, in this paper, the author closely reviewed the theories of poetry that is appeared, especially, in the three volumes of ${\ll}$Talks on Chinese Poetry${\gg}$ among the collections of Wang's poetry criticism. In particular, the author investigated the positive and negative aspects of Honam's commentaries on the works by Chinese poets, including his principles of poetics, creative skills, and practical criticism, etc. Wang Yak-heo has not been known much in the history of Chinese literary thoughts, however, his theory of criticism, especially, among the talks on Chinese the works by Chinese poets, his literature criticisms establish unique and distinctive point of views. Wang Yak-heo's poetics, more than anything else, valued nature, meanings, truth, and contents therein. He exhibited realistic view of literature. Meanwhile, he analyzed the methods of expression by Du Bo(杜甫, pronounced, "Du Fu" in Chinese), So Sik, also known as So Dong Pa (蘇軾, Su Shi or 蘇東坡, Su Dong Po in Chinese), and Hwang Jeong-gyeon(黃庭堅, Huang T'ing-chien), and highly evaluated the realistic poems written by Du Bo, Baek Geo-I (白居易, pronounced, "Bai Juyi" in Chinese), and So Sik. Also, he opposed to formalism or externality, however, he never made light of formality of poetry. In his comments on the works by Chinese poets, he highly evaluated the poems sung by So Sik and Beek Geo-I, in the mean time, however, he criticized their works without hesitation. Having set up his own unique criteria for critique, Wang didn't accept other opinions in a seemingly illogical manner, and he presented what he thoughts and other different points of view from others. Specifically, he attached great importance to whether or not modification of words and phrases, grammar, and whole context were congruent to one another and had been well harmonized. However, in his poetics, Wang was so wrapped himself in reasonableness or rationality, he analyzed each and every word in great detailed manner, as the result, he sometimes didn't read the sentiment or mood that the writers intended to express through poems. He excessively restricted himself to the words and phrases, so that he was not able to realize natural emotions and joy of imagination that were presented in the poems, and, in the end, this brought about adverse effects to the poet's thought.

Recently, duck meat consumption has been rapidly increased because consumers recognized duck meat for healthy food. In relation to this, Korean duck industry need to develop Korean native duck (KND) breed for both conservation perspective and self-sufficient of the breeding stocks. In this study, 24 microsatellite (MS) markers were investigated for classification of KND and commercial duck (CD) breeds in the Korean market. Using these MS markers, the calculated number of alleles (K), expected heterozygosity (He) values and polymorphic information contents (PIC) were 1~16, 0~0.865 and 0~0.841, respectively. Also, the expected probability of identical values in random individuals (PI), random sib ($PI_{sib}$) and random half-sib ($PI_{half-sib}$) were estimated as $1.64{\times}10^{-16}$, $2.60{\times}10^{-7}$ and $1.30{\times}10^{-12}$, respectively. The results indicated that the expected probabilities of identity powers were enough for the individual identification. However, KND and CD breeds were not fully discriminated well using the 24 MS markers, which may CD and KND has shared same origin or crossbred. Therefore, further studies will be ultimately needed for developing a genetically pure line of KND breed even though the DNA markers used. Finally, these results will provide useful information for individual traceability system in ducks.

This study focuses on the investigation of geologic distribution and stratigraphy in the eastern part of Yeongdeok-gun, based on Lidar imaging, detailed field survey, microscopic observations, SHRIMP and LA-MC-ICPMS U-Pb age dating, and a new geological map has been created. The stratigraphy of the study area is composed of the Paleoproterozoic metamorphic rocks consisting of banded gneisses of sedimentary origin and schists ($1841.5{\pm}9.6Ma$) of volcanic origin, Triassic Yeongdeok plutonic rocks ($249.1{\pm}2.3Ma$) and Pinkish granites ($242.4{\pm}2.4Ma$), Jurassic Changpo plutonic rocks ($193.2{\pm}1.9Ma{\sim}188.8{\pm}2.0Ma$) and Fine-grained granites ($192.9{\pm}1.7Ma$), Formations [Gyeongjeongdong Fm, Ullyeonsan Fm. (~108 Ma), Donghwachi Fm.] of the Early Cretaceous Gyeongsang Supergroup and acidic volcanic rocks and dykes erupted and intruded in the Late Cretaceous, Miocene intrusive rhyolitic tuffs ($23.1{\pm}0.2Ma{\sim}22.97{\pm}0.13Ma$) and sedimentary rocks of the Yeonghae basin, and the Quaternary sediments. The Triassic Pinkish granites, Jurassic Changpo plutonic rocks and Fine-grained granites are newly defined plutonic rocks in this study. Miocene intrusive rhyolitic tuffs bounded by the Yangsan Fault, which was first discovered in the north of Pohang city, are believed to play an important role in the understanding of the Miocene volcanic activity and the crustal deformation history on the Korean Peninsula. It is confirmed that The NNE-SSW-striking Yangsan Fault penetrating the central part of the study area and branch faults are predominant in the dextral movement and cutting all strata except the Quaternary sediments.

Background : It is well known that only 10% of those infected with Mycobacterium tuberculosis actually develop clinical disease, indicating the existence of host genetic factors regulating disease expression. In this study, we investigated HLA-DRB1 and -DQB1 gene polymorphisms in Korean patients with pulmonary tuberculosis (PTB). Methods : HLA-DRB1 and -DQB1 gene polymorphisms were investigated in 67 PTB patients without previous treatment history, 38 drug-sensitive (DS) and 29 multidrug-resistant (MDR) cases, and 200 healthy controls. HLA-DRB1 typing was done using reverse SSO (sequence specific oligonucleotide) and PCR-SSCP (single strand conformational polymorphism) methods and DQB1 typing was done using PCR-RFLP (restriction fragment length polymorphism), PCR-SSCP and PCR-SSP (sequence specific primer) methods. Results : Among the PTB patients, MDR-TB cases showed frequencies of DRB1*0701 and *08032 increased by about two-fold compared to those of normal controls, and likewise for their associated DQB1 alleles, DQB1*0202 and *0601 (15.5% vs. 34.5%, p=0.01). The frequency of HLA-DQB1*0609 was significantly increased in PTB patients (4.0% vs. 14.9%, p=0.004), showing similar increases in both DS and MDR cases. There was also an association of HLA alleles with the clinical severity of the disease according to the extent of lung lesion. Significantly increased frequencies of DRB1*08032 (4.2% vs. 32.6%, p=0.007) and DQB1*0601 (12.5% vs. 34.9%, p=0.047) were observed in more advanced (moderately & far advanced/DS and far advanced/MDR), compared with less advanced (minimal/DS and moderately advanced/MDR) lung lesions. Although DRB1*0701, DQB1*0202 and DQB1*0609 showed significant increases in different subsets of the disease, these HLA alleles did not show consistent association with disease severity. Conclusion : HLA-DRB1*08032 and DQB1*0601 alleles were associated with genetic susceptibility to MDR-TB in Korean patients, and also with disease severity and progression of PTB.

In this paper, we report what we have observed with regard to user-perspective issue clustering based on multi-layered two-mode network analysis. This work is significant in the context of data collection by companies about customer needs. Most companies have failed to uncover such needs for products or services properly in terms of demographic data such as age, income levels, and purchase history. Because of excessive reliance on limited internal data, most recommendation systems do not provide decision makers with appropriate business information for current business circumstances. However, part of the problem is the increasing regulation of personal data gathering and privacy. This makes demographic or transaction data collection more difficult, and is a significant hurdle for traditional recommendation approaches because these systems demand a great deal of personal data or transaction logs. Our motivation for presenting this paper to academia is our strong belief, and evidence, that most customers' requirements for products can be effectively and efficiently analyzed from unstructured textual data such as Internet news text. In order to derive users' requirements from textual data obtained online, the proposed approach in this paper attempts to construct double two-mode networks, such as a user-news network and news-issue network, and to integrate these into one quasi-network as the input for issue clustering. One of the contributions of this research is the development of a methodology utilizing enormous amounts of unstructured textual data for user-oriented issue clustering by leveraging existing text mining and social network analysis. In order to build multi-layered two-mode networks of news logs, we need some tools such as text mining and topic analysis. We used not only SAS Enterprise Miner 12.1, which provides a text miner module and cluster module for textual data analysis, but also NetMiner 4 for network visualization and analysis. Our approach for user-perspective issue clustering is composed of six main phases: crawling, topic analysis, access pattern analysis, network merging, network conversion, and clustering. In the first phase, we collect visit logs for news sites by crawler. After gathering unstructured news article data, the topic analysis phase extracts issues from each news article in order to build an article-news network. For simplicity, 100 topics are extracted from 13,652 articles. In the third phase, a user-article network is constructed with access patterns derived from web transaction logs. The double two-mode networks are then merged into a quasi-network of user-issue. Finally, in the user-oriented issue-clustering phase, we classify issues through structural equivalence, and compare these with the clustering results from statistical tools and network analysis. An experiment with a large dataset was performed to build a multi-layer two-mode network. After that, we compared the results of issue clustering from SAS with that of network analysis. The experimental dataset was from a web site ranking site, and the biggest portal site in Korea. The sample dataset contains 150 million transaction logs and 13,652 news articles of 5,000 panels over one year. User-article and article-issue networks are constructed and merged into a user-issue quasi-network using Netminer. Our issue-clustering results applied the Partitioning Around Medoids (PAM) algorithm and Multidimensional Scaling (MDS), and are consistent with the results from SAS clustering. In spite of extensive efforts to provide user information with recommendation systems, most projects are successful only when companies have sufficient data about users and transactions. Our proposed methodology, user-perspective issue clustering, can provide practical support to decision-making in companies because it enhances user-related data from unstructured textual data. To overcome the problem of insufficient data from traditional approaches, our methodology infers customers' real interests by utilizing web transaction logs. In addition, we suggest topic analysis and issue clustering as a practical means of issue identification.

Reclamation is the act of creating new lands by constructing dikes in offshore tidal flats to utilize them for various purposes, including the establishment of farmland to secure food for an increasing population. Based on the fact that reclamation has resulted in drastic changes in the environmental, economic, social, and cultural aspects of land expansion and development, population movement, and the formation of cities since ancient times, I reviewed the value of reclamation sites and addressed the issue of how to preserve and utilize them. "Reclamation culture" refers collectively to the recognition and concept system, behavior styles, and cultural products created by changes in the environment, and the tangible, intangible, and natural heritage generated directly and indirectly by reclamation is defined as "reclamation cultural heritage". It shows that the historical background of reclamation accords with prevailing trends, and that the reclamation sites possess cultural heritage value due to their historical, academic, and scarce characteristics. Numerous reclamation cultural heritage sites at the Gwangwhal and Gyehwa dikes are on the verge of being destroyed, with their original function having ended after the construction of Saemangeum Sea Wall. I propose measures to preserve these under the principle that utilization is based on the basic premise of conservation. First of all, modern and contemporary reclamation sites must necessarily be designated and managed as registered cultural properties, local cultural heritage, future heritage, and agricultural heritage. In particular, as it has been confirmed that reclamation sites created after the Goryeo and Joseon dynasties and the 1950s have not been designated as cultural heritage sites. It is necessary to review the characteristics and values of such reclamation sites through a full survey of national reclamation data. Effective and sustainable utilization of reclamation cultural heritage, which has not been acknowledged in the past due to its close relationship with our lives, is necessary to search for hidden stories found within that heritage, to organize governance for the efficient use of reclamation resources, and to build a museum to collect and display the history and culture of the reclaimed areas. Finally, through links with countries with experience in reclamation, we will be able to cope jointly with international issues such as those pertaining to society, culture, and environment, and would be able to implement various projects to further the advancement of human beings.

This article examined that the historical changes and current significance of the Jaedam(재담) and the Xiangsheng(相聲), one of the traditional Korean and Chinese language games. Both Korean Jaedam and Chinese Xiangsheng are representative language games and traditional performing arts for laughing. The origin of the Jaedam can be traced back to Uheui(우희). Uheui has been called Changyouxi in China, Bae Woo-hee, and Jo Hee in Korea. Uheui is the most traditional language game and a variety of performances were derived from its spreading and inheriting process. Among them, Korean Jaedam and Chinese Xiangsheng can be said to be a piece of art that has successfully inherited Uheui tradition. From the late 18th century, Korean Jaedam were established as independent performance arts, and became highly active in many performance by professional joker Park Chun-jae and other performers. With the development of gramophone record in the early 20th century, the Jaedam was mainly made on the theater stage and radio. At this time, the new performance art of 'Mandam(만담)' was derived from the Jaedam, which focused more on satire current events and criticizing the social situation. Mandam has been popular for a long time and then extinct in the 21st century. The jaedam have been handed down only in the Korean traditional performance so far. Meanwhile, Chinese Xiangsheng, which was built in the mid-19th century, a bit later than Korean Jaedam, was initially considered to be a vulgar art of the lower class, but finally became popular in the early 20th century. In the mid-20th century, Xiangsheng was transformed into a new character, which mainly deals with social praise and edification of the masses. But since 'New Xiangsheng' does not focous on a satire on social conditions, the humor has been reduced. In the early 21st century, Xiangsheng was on the verge of extinction just like Mandam, but through the efforts of young actors to revive tradition, another reformation of this art was made to return to tradition and small theater. Currently, the 'traditional Xiangsheng', which has returned to tradition, is once again receiving the love and support of the Chinese audience. Korean Jaedam and Chinese Xiangsheng have many similarities in terms of history and recruitment, but they are now in different fates. There is also a great deal in common ground in terms of the content and form of the two arts. In the case of Xiangsheng, it is one of the traditional folk art forms which is still loved by the Chinese people and has become one of the most important traditional performances. On the other hand, in Korea, Jaedam as independent performance arts has disappeared and now only can be seen in traditional performances such as 'Korean mask theater'. The fact that Korean Jaedam and Chinese Xiangsheng have undergone similar changes in their spreading and inheriting process, while Korean Jaedam have disappeared and Chinese Xiangsheng is well preserved. The reason can be confirmed through the main idea of this article.
