A spirit tablet of king Guan Yu is enshrined in Donggwanwangmyo shrine[East Shrine of King Guan Yu], which houses 51 hanging boards. The hanging boards were written by the kings of Joseon Dynasty and envoys and generals of the Ming and Qing Dynasties. Most studies on hanging boards have been focused on the collections of the palaces but not on those in Donggwanwangmyo shrine. In this regard, this study researches the hanging boards of the kings' writings in the late Joseon period and analyzes their forms and contents. In terms of contents, it examines who made the boards, when they made them, and what brought them to make them, etc. This study analyzes the forms of hanging boards by types, used materials, and periodic transition of forms. The findings are as follows. First, Donggwanwangmyo shrine houses 7 pieces of hanging boards inscribed with kings' handwriting: one piece of King Sukjong, 4 pieces of King Yeongjo, and 2 pieces of Emperor Gojong. They are divided into two types: one is the name of the buildings and the other is the poems that the kings wrote regarding what they felt when they visited the shrine. Especially, the latter were written by the kings who visited the shrine in spring and autumn. The kings intended to promote peace of royal family through a sense of royalty and fidelity of King Guan Yu. Second, the hanging boards of the kings are differentiated from those of the envoys and generals of the Ming and Qing Dynasties in materials and forms. The background of the board is colored by blue, deep red lacquer color, and black lacquer color, which are more expensive than black color or white color. The hanging boards are embossed with the kings' handwritings and then colored with gold. The frame-style four-side hanging board is held at a 45-degree angle and painted with floral patterns and seven-treasure patterns in Dancheong technique. The left and right sides and the top and bottom sides of the board are decorated with Dang-cho pattern(Korean arabesque pattern). This style is called "quadrilateral"and considered the most classy and top-class among the other three ones. In conclusion, this study confirms the status of Donggwanwangmyo shrine with hanging boards inscribed with kings' handwritings as a political space where kings had interest and demanded their soldiers' royalty and fidelity. Research into the boards inscribed with the handwritings of envoys of the Ming Dynasty and generals of the Qing Dynasty, and the comparison of the styles and periodic transition of forms will be reserved for another study.

Sam-Tai-Ji has been used as one of the korean traditional symbol patterns including the emblem of the Seoul olympic. Despite Sam-Tai-Ji included in 태극(Tai-Ji:太極), it has been interpreted widely as Sam-jae(三才)theory called Tian(天), Di(地) and Ren(人), or Tian, Di and Ren harmony thought(天地人 調和思想) by some religion groups and some intelligent people without exact philosophical poofs. For this reason, this research on Tai-Ji(太極) pattern follows. Although Joseon dynasty selecting Confucianism as a ruling principle, it accepted Buddhism, Taoism and Shamanism by applying them to royal tombs not officially but privately. For example, If Confucianism has to be expressed in the public places, Er-Tai-Ji(二太極) pattern having an expressing type of Li-Ben-Lun(理本論) was employed, in the private places like royal tomb construction, Er-Tai-Ji(二太極) pattern having an expressing type of Qi-Ben-Lun(氣本論) was employed. To figure out clear identification of Sam-Tai-Ji(三太極) and Er-Tai-Ji(二太極), this research was conducted to study on the change process of Tai-Ji(太極). It has been considered that Tai-Ji(太極) pattern has something to do with universe in these countries such as Korea, China and Japan. In Tai-Ji(太極) pattern, Sam-Tai-Ji had been used more widely than Er-Tai-Ji(二太極) untill the Han Dang dynasty. The meaning is also indicated as Yin-Yang-Te(陰陽德) in the books like "Hanseo(漢書)" "Yulryeokji(律曆志)". But, in the chinese history, there was a change of the pattern into white spot Er-Tai-Ji(二太極) in "KoTaiJiDo(古太極圖)". It had been interpreted as "Yin-Yang and vitality(陰陽生氣)." since Song Dynasty when Confucianism settled down. In this process, unlike Wu-Ji(無極), Li(理) means immateriality. So Yin-Yang(陰陽) and Li(理) were expressed with the form of Er-Tai-Ji(二太極). Therefore, Sam-Tai-Ji(三太極) is the pattern that stands for Yin-Yang-Te(陰陽德). It means that Yin-Yang(陰陽) gives a life to all the living things, grows them along with Te(德). It developed and flourished in Taoism and Buddhism accepting spirit existence. It is the universe view that Qi(氣) is an entity.

King Jeongjo had lost his father, Sado-Seja(Prince Sado) by Noron(Older Faction). Especially those who tried to kill Sado-Seja and king Jeongjo consisted of king's family-in-law of king Youngjo and Sado-Seja. Therefore king Jeongjo's first goal was to strengthen his kingship than other things because he could gain the throne overcoming the strong hinderance of Noron and king's family-in-law. King Jeongjo requested his subjects to be "Kukbyon-In"(國邊人: a person for king) pointing out the harm of the king's family-in-law and "Tangpyong-Dang"(蕩平黨: the strongest faction consisted under the rule of king Youngjo). For the purpose, king Jeongjo built up "Gyujang-Gak". Gyujang-Gak was spoken to contain and protect the writings of earlier kings superficially, but in reality, it was an apparatus to gain and train the friendly subjects for king Jeongjo. Like that, it was the most important for king Jeongjo to suppress the king's family-in-low and to win Neo-Confucian lterati over to himself's side. Until now, the politics of Joseon Dynasty had been mainly explained on the point of view of "Seonghak-Non"(聖學論). "Seonghak-Non" means that Neo-Confucian lterati were treated as real hero, not kings in the political space of Joseon Dynasty and the role of factions were recognized important. But king Jeongjo denied these ideological stream and tried to change that political system. King Jeongjo wanted to strengthen the throne through the method which insisted the king as a hero in politics. For the purpose, king Jeongjo criticized the Neo-Confucian literati's viewpoint about politics and learning at that time and anticipated to be sole leader of politics and learning on that critique. King Jeongjo aimed to destroy the dignity of "Salim"(山林: Neo-Confucian Sages) with attacking their wrong behaviors. King Jeongjo also criticized the period of king Injo when the regime of "Sarim"(士林: pure Neo-Confucian lterati) faction fully appeared as the starting period when the factional harms were getting worse. King Jeongjo wanted to previously block the oppositions to win subjects over to himself's side with criticizing the period of king Injo and to take away the initiative from his opponents with insisting "Salim-Muyongnon"(山林無用論: a theory ignoring Neo-Confucian Sages). King Jeongjo's critique was not limited just on the system of factional politics. "Seonghak-Non" eventually took root in Neo-Confucianism. Therefore king Jeongjo criticized Neo-Confucianism. He insisted that the essence of Chinese Classics was pragmatical learning, not Neo-Confucianism. Through that critique, king Jeongjo aimed to destroy the ideological base of his opponents. However, king Jeongjo failed to be a sole leader of his subjects in the both boundaries of politics and learning even though he criticized the Neo-Confucian lterati's viewpoint about politics and learning. Because he abruptly died leaving his reformational scheme behind as well as his loyal subjects guarding himself against Noron Byeok-Pa(老論 ?派: the opposing party in Older Faction) were gone behind himself. The politics of Joseon Dynasty returned to more powerful politics for king's family-in-law after king Jeongjo's death.

Bronze mirrors found in pagodas were regarded as simple offerings and thus have received little attention in studies. Furthermore, the few studies on bronze mirrors enshrined in pagodas have focused on the line-engraved mirrors found in the pagodas of the Kingdom of Wuyue; therefore, it is difficult to understand the general characteristics of the bronze mirrors enshrined in the pagodas. This study assumes that the bronze mirrors found in many pagodas in the Kingdom of Wuyue and the Song dynasty were enshrined for a specific purpose. To explore this assumption and accurately understand the artifacts, this study focuses on the location and method of enshrinement. The number of bronze mirrors enshrined in pagodas increased during the Kingdom of Wuyue, with the mirrors expressing statues and inscriptions related to Buddhism rather than being simple offerings. This shows that the purpose of the bronze mirror changed. The influence of the Kingdom of Wuyue continued during the Song dynasty; however, the pattern of bronze mirror enshrinement changed due to the culture and social atmosphere of the time. The most common types of enshrined bronze mirrors were plain, and bronze mirrors from the Dang dynasty were also used consistently. Plain bronze mirrors were used more frequently in this period despite the lingering influence of the Kingdom of Wuyue because it was less laborious to engrave images and inscriptions such as the inscription of Buddha. Additionally, bronze mirrors were valued during this period because of the attention toward the imitation of the archaic bronze(仿古銅器) of the Song dynasty and the influence of the emperor. Moreover, it is believed that bronze mirrors were enshrined in pagodas as offerings as they were deemed valuable at the time. There was a change in the method of enshrining bronze mirrors in pagodas during the Kingdom of Wuyue and the Song dynasty. During this time, bronze mirrors that were positioned on the floor or in iron boxes were intentionally attached to walls or hung from the ceiling. This method was largely divided into two types: attaching to walls or the ceiling(嵌入鏡) and hanging from the ceiling(懸鏡). A typical example of hanging a bronze mirror from the ceiling can be seen in the Jingzhisa Temple Pagoda, and Teng County's Fushengsa Temple Pagoda contains an example of attaching a bronze mirror to the ceiling. The methods of hanging or attaching bronze mirrors to the ceiling were closely related to the methods employed in Chinese tombs. Song dynasty burial chambers had a high and wide structure, so to defend against evil spirits(辟邪用), bronze mirrors were used to protect the burial rooms. Bronze mirrors were, therefore, placed high to illuminate the burial room. This was achieved in the ways mentioned above. As underground chambers became wider and higher, mirrors also protected the important areas of the chambers and illuminated the interiors. Thus, it is believed that the methods of enshrining bronze mirrors in the pagodas during the Kingdom of Wuyue and the Song dynasty arose from the method of enshrining bronze mirrors in tombs at the time. Thereafter, pagodas, such as the Miaojuesa Temple Pagoda, in which the placement of a bronze mirror was actively considered from the design stage were constructed.

This study was aimed to identify the phenotypic relationships between calving interval and lactation curve parameters in Korean Holstein cow. The data of 36,505 lactation records was obtained from the Dairy Herd Improvement program run by Dairy Cattle Improvemnet Center of National Agricultural Federation of Korea. All lactation records were collectied from the multiparous cows calving between 2011 to 2013. The estimated lactation curves were drawn using Wood model based on actual milk yield records, and NLIN Procedure of SAS program (ver. 9.2). General linear multivariate models for calving interval, 305-d milk yield, lactation parameters(A, b, c), persistency, peak day, and peak yield included fixed effects of calving year-season (spring, summer, fall and winter) and parity(2, 3 and 4). For calving interval, 305-d milk yield, lactation parameters(A, b, c), persistency, peak day and peak yield, all two fixed effect(calving year-season, parity) were significant(p<0.05). The estimated lactation functions using Wood model for 2, 3, and 4 parity were yt=24.66t0.175e-0.00302t, yt=24.69t0.192e-0.00334t, and yt=24.22t0.200e-0.00341t, respectively. Phenotypic correlation (partial residual correlation) between calving interval and 305-d milk yield, A, b, c, persistency, peak day, and peak yield were 0.093, -0.014, 0.028, -0.046, 0.099, 0.085, and 0.052, respectively. To conclude, if calving interval increase then ascent to peak, persistency, peak day and peak yield are increase, and descent after peak is decrease. So, total 305-d milk yield is increase.

The study was aimed to analyze pedigree structure and inbreeding coefficients for performance tested Holstein cows in Korea. A total of 400,029 Holstein cows data which born between 2002 and 2012 were obtained from Dairy Cattle Improvement Center of National Agricultural Cooperative Federation(NACF). Their related pedigrees, as obtained from Korean Animal Improvement Association(KAIA), consisted of 509,740 animals. Pedigree depth of the cows were traced back to 3 generations earlier. The percentage of cows with fully identified ancestors in various provinces of Korea were 55.18%(Gyeonggi-do), 23.49%(Gangwon-do), 47.83%(Chungcheongnam-do), 53.62%(Chungcheongbuk-do), 56.38%(Gyeongsangbuk-do), 51.35% (Gyeongsangnam-do), 26.58%(Jeollanam-do), 49.41%(Jeollabuk-do), and 56.90%(Jeju-do), whereas, it was about 63.20% as a whole in Korea. The average inbreeding coefficients showed increment across the consecutive years of birth such as, 0.43(2002), 0.44(2003), 0.58(2004), 0.64(2005), 0.78(2006), 0.93(2007), 1.08(2008), 1.23(2009), 1.46(2010), 1.77(2011), and 2.03 (2012). However, this coefficient was 0.93 in overall Korean population. An average generation interval for sire to daughter genetic path was 8.15 years; which was about 4.20 years considering dam to daughter genetic path. The estimated effective population sizes (Ne) were 56.5, 51.3, and 32.2 animals born in 2004, 2009, and 2012, respectively. These results indicated that an increased rate of inbreeding has led to a significant reduction in the Ne over the decade.

This study was conducted to estimate genetic parameters for milk production and linear type traits in Holstein dairy cattle in Korea. The data including milk yields, fat yields, protein yields, fat percent, protein percent, somatic score and 15 linear type traits for 10,218 first parity cows collected by Dairy Cattle Improvement Center, National Agricultural Cooperative, Korea, which were calving from January 2009 to April 2013. Genetic and error (co)variances between two traits selected form 19 traits were estimated using bi-trait pairwise analyses with WOMBAT package. The estimated heritabilities for milk yield(MY), fat yield(FY), protein yield(PY), fat percent(FP), protein percent(PP), somatic cell score(SCS), udder depth(UD), udder texture(UT), median suspensory(MS), fore udder attachment(FUA), front teat placement (FTP), rear attachment height(RAH), rear attachment width(RAW), rear teat placement(RTP), front teat length(FTL), foot angle(FA), heel depth(HD), bone quality(BQ), rear legs side view(RLSV), rear legs rear view(RLRV) and locomotion(LC) were 0.128, 0.144, 0.100, 0.273, 0.333, 0.090, 0.179, 0.066, 0.104, 0.109, 0.127, 0.099, 0.059, 0.069, 0.154, 0.014, 0.010, 0.052, 0.065, 0.175 and 0.031, respectively. Among the genetic correlations, UD, UT, FTP, RAW, FTL, FA and RLSV with MY were -0.334, 0.271, 0.445, 0.544, 0.076, -0.281 and -0.228, respectively, and MS, FTP, RTP, FTL, FA, BQ, RLSV, RLRV and LC with PP were -0.147, -0.182, -0.262, -0.136, 0.355, 0.311, 0.135, 0.233 and 0.143, respectively. Especially, MY had the highest positive genetic correlation with RAW (0.544), while SCS had the highest negative genetic correlation with LC (-0.603). FP had negative genetic correlation with most udder traits, whereas, FP had positive genetic correlation with leg and hoof traits (0.056 - 0.355).

Pungsu is an ancient logic that systemizes geography based on the Yin-Yang and The Five Elements Principle. It is defined as the unique and highly systemized ancient Eastern art of selecting auspicious sites and arranging harmonious structures such as graves, houses, and cities on them by evaluating the surrounding landscape and cosmological directions. Pungsu helps allegedly one improve life by receiving vital energy(Shengqi, 生氣)-energy flow that flows under the ground. It is traditional belief that the living lead their lives on the ground, indirectly receiving the energy coming out of the ground, whereas the dead are buried under the ground, allowing them to directly absorb energy from the ground, which makes Shengqi the dead receive bigger and more obvious than that the living receive. This energy absorbed by the dead from the ground was believed to be passed on to their descendants. This phenomenon is called "Induction of vital energy between Ancestors and Descendants". People searched for the sites which were believed to contain rich and positive vital energy flow. They also tried to bury their ancestors under such sites hoping to receive the Shengqi coming from underground which they believed would help them thrive and prosper. The efforts to locate the sites which have the most vital energy, auspicious sites or "Bright Yard(明堂)", are easily observed in Asia including China and Korea. The ultimate goal of searching for auspicious sites lies in human(whether alive or dead) receiving vital energy from the nature to enjoy happy lives. In choosing a place to live or to bury their dead ancestors, people tried to understand the energy flow of the site considering the factors related with mountain, water, and direction. If we take a closer look into the methods of finding auspicious sites, we can see that people have tried to see the outer conditions of lands, mountains and waters within the perfect harmony if possible. Auspicious site or Bright Yard is the site with those elements in perfect order and harmony, that is, it is the place which derives the most vital energy from the best order and harmony of nature. As this shows, an auspicious site symbolizes totality-the Self, and it seems to be projected to the land. It is believed to be an attempt that the reason why we try to find auspicious sites to internalize the totality that we projected to the outer world. Therefore, this auspicious site is what our foremost values, symbol of the Self, such as harmony, equilibrium, perfection, and uniqueness are reflected to the land. Through the process of finding such a site, we try to gain totality of psyche.

This study analyses the difference of contents and tones of arguments among three Korean major newspapers, the Kyunghyang Shinmoon, the HanKyoreh, and the Dong-A Ilbo. It is commonly accepted that newspapers in Korea explicitly deliver their own tone of arguments when they talk about some sensitive issues and topics. It could be controversial if readers of newspapers read the news without being aware of the type of tones of arguments because the contents and the tones of arguments can affect readers easily. Thus it is very desirable to have a new tool that can inform the readers of what tone of argument a newspaper has. This study presents the results of clustering and classification techniques as part of text mining analysis. We focus on six main subjects such as Culture, Politics, International, Editorial-opinion, Eco-business and National issues in newspapers, and attempt to identify differences and similarities among the newspapers. The basic unit of text mining analysis is a paragraph of news articles. This study uses a keyword-network analysis tool and visualizes relationships among keywords to make it easier to see the differences. Newspaper articles were gathered from KINDS, the Korean integrated news database system. KINDS preserves news articles of the Kyunghyang Shinmun, the HanKyoreh and the Dong-A Ilbo and these are open to the public. This study used these three Korean major newspapers from KINDS. About 3,030 articles from 2008 to 2012 were used. International, national issues and politics sections were gathered with some specific issues. The International section was collected with the keyword of 'Nuclear weapon of North Korea.' The National issues section was collected with the keyword of '4-major-river.' The Politics section was collected with the keyword of 'Tonghap-Jinbo Dang.' All of the articles from April 2012 to May 2012 of Eco-business, Culture and Editorial-opinion sections were also collected. All of the collected data were handled and edited into paragraphs. We got rid of stop-words using the Lucene Korean Module. We calculated keyword co-occurrence counts from the paired co-occurrence list of keywords in a paragraph. We made a co-occurrence matrix from the list. Once the co-occurrence matrix was built, we used the Cosine coefficient matrix as input for PFNet(Pathfinder Network). In order to analyze these three newspapers and find out the significant keywords in each paper, we analyzed the list of 10 highest frequency keywords and keyword-networks of 20 highest ranking frequency keywords to closely examine the relationships and show the detailed network map among keywords. We used NodeXL software to visualize the PFNet. After drawing all the networks, we compared the results with the classification results. Classification was firstly handled to identify how the tone of argument of a newspaper is different from others. Then, to analyze tones of arguments, all the paragraphs were divided into two types of tones, Positive tone and Negative tone. To identify and classify all of the tones of paragraphs and articles we had collected, supervised learning technique was used. The Na$\ddot{i}$ve Bayesian classifier algorithm provided in the MALLET package was used to classify all the paragraphs in articles. After classification, Precision, Recall and F-value were used to evaluate the results of classification. Based on the results of this study, three subjects such as Culture, Eco-business and Politics showed some differences in contents and tones of arguments among these three newspapers. In addition, for the National issues, tones of arguments on 4-major-rivers project were different from each other. It seems three newspapers have their own specific tone of argument in those sections. And keyword-networks showed different shapes with each other in the same period in the same section. It means that frequently appeared keywords in articles are different and their contents are comprised with different keywords. And the Positive-Negative classification showed the possibility of classifying newspapers' tones of arguments compared to others. These results indicate that the approach in this study is promising to be extended as a new tool to identify the different tones of arguments of newspapers.

This study was conducted to formulate management guidelines for Natural monumental old trees in Korea through survey of tree vigor and analysis of growing environments. A total of 20 old trees designated as natural monuments in Seoul, Incheon, and Gyeonggi Province were surveyed. The biological characteristics were surveyed with 4 items of species, ages and height of trees. The surrounding environments were surveyed with 2 items of location types and surroundings. The root conditions were surveyed with 2 items of denudation and molding depth. The health conditions were surveyed with 5 items of withering rate, cavity size, bark breakaway rate, damages by blight and insects, and growing tips. The soil conditions were surveyed with 6 items of PH, organic contents, valid phosphoric acid, transposal cations(K, Ca) and soil compaction. On the basis of outcomes of these research items, mutual relations among locations, growings and soil conditions of old trees were analyzed by carring out cross tabulation, correlation, and simple and multiple regression. Management guidelines were presented searching the factors effecting on the health of the monumental old trees. On the biological characteristics, the old trees designated as natural monuments were Pinus bungeana(4 trees), Juniperus chinensis(3 trees), Ginkgo biloba(3 trees), Poncirus trifoliata(2 trees). Actinidia arguta, Wisteria floribunda, Thuja orientalis, Quercus mongolica, Sophora japonica, Fraxinus rhynchophylla, Zelkova serrata, and Pinus densiflora. The tree height ranged from 4.2 to 39.2m, and root collar rounds ranged from 1.01 to 15.2m. On the surrounding environments, The location types ; Gardens(4), historical sites(5), residental sections(3) open agricultural fields(3), mountain hills(3), and near ocean beaches(1) and stream site(1). The surroundings ; 75% denudation of roots, molded more than 10cm except 4 trees(25%). On the health conditions, 1)Withering rate ; Ginkgo biloba(20%) in Yongmoon temple, (5%) in Saki-ri, kanwha-gun, and others had no withering rate. 2) Cavity size ; all subject had $5{\sim}100cm^3$ of cavity. 3) Bark breakaway rate ; Pinus bungeana in Soosong-dong, in the shrine of Confucius, in Samchung-dong, especially high rate of cavity(5~50%) in Seoul area and in Saki-ri, Kangwha-gun were high 45% brakeaway rate. 4) Damages by blight and insects was slight due to managements. 5Growing tips ; In cases of Juniperus chinensis in Changdeok palace and SunnogDang, seoul, growing tips were 1/2, presumably cause by air pollution, and in cases of Fraxinus rhynchophylla in Paju city and Pinus densiflora in BacksaDorip-ri, Icheon city, growing tips were fine, presumably because there were no moldings. On the Soil conditions, Soil pH ranged from 5.2 to 8.3, organic matter contents from 12% to 56%, phosphorus contents from 104 to 618ppm, soil compaction ranged from 7 to 28mm( among them, Denudation was severe with 21~28mm soil compactions in cases of Pinus bungeana in Soosong -dong, Thuja orientalis in Samchung -dong, Ginkgo biloba in the shrine of Confucius and in Yongmoon temple.) Results of cross tabulation, correlation, and regression analysis showed that molding depth was the most serious factor to deteriorate the tree vigor and cambium conductivity. In addition, soil acidity, organic matter contents, disease and insect damages and cambial detachment were also related to the tree vigor. Additional research of these relationships will be needed to conduct more detailed studies. Based on the relationships between the tree vigor and growing environments, it is considered that old trees should be managed to give them more growing spaces and less abuses. Also, molded soils should be removed and further soil-molding around the tree collar should be prohibited. For the construction of systematic management and removal of harmful factors, appropriative management according to spices, persistent monitering of damaged cases and construction of management system through the accumulation of data on the relationships of soil conditions are required.
