Yellow-hearted pine (YHP; Pinus densiflora for. erecta Uyeki) is one of the Red pine species and has extremely narrow growth ring and high ratio of heartwood growing in Korea. It has been used for valuable wooden constructions as palace and temple for royal family since the Joseon Dynasty period. However, scientific information on the wood properties of YHP is still very lacking. This study was carried out to investigate natural durability of YHP to fungi and termites attack. Examination of anti-fungal and anti-termite properties of YHP was performed at indoor condition using brown-rot fungi (Fomitopsis palustris), white-rot fungi (Trametes versicolor), and termite (Reticulitermes speratus). The results showed that weight loss of the heartwood in YHP after fungi and termite test was much lower than those of the sapwood in YHP. Furthermore, the highest mortality of termite was obtained from the heartwood of YHP. Consequently, it is clearly revealed that the heartwood of YHP has excellent durability against brown- and white-rot fungi and termite.

'The Three Bonds And The Morals in Human Relations' was published in Joseon Dynasty period in 1434, relatively early days of comic history in the world. The gaps between comics frames have symbolic meaning as comics frames have in the area of symbols of comics. After comics frames appeared, it was likely that the advent of the gaps between frames had its own value in the aspect of comics history. Historical backgrounds of domestic comics would be built on firm base led by studying on the symbolic meaning of the gaps between comics frames. Two forms of the gaps between frames were shown in 'The Three Bonds And The Morals in Human Relations.' The first form is the gap between cloud frames. The second is the gap between cloud frame and background frame. Although a little difference is found in the shape and display, two forms of the gaps between frames in 'The Three Bonds And The Morals in Human Relations' have a similarity to modern comics. This study is to demonstrate valid background for the domestic history of comics by means of analyzing the shapes of the gap between comics frames in 'The Three Bonds And The Morals in Human Relations.' The objective of this study is to prove the meaning of the shapes of the gaps between comics frames 'The Three Bonds And The Morals in Human Relations', focusing the gaps between frames among symbols of comics.

Plato's ontology is closer to Holism, which is based on IDEA, than to Dualism, which regards the matter and soul as being independently from each other. According to his metaphysics, the sensory things are the copies of IDEA. and IDEA is the original of them. Hence human body and soul are not separate from each other, but are ontologically continuous and functionally complementary. The reason why Plato's view of education, which pursues the perfection of the soul, emphasizes the physical training and makes it the premise of study is this ontology. It seems that Park Eun-sik, an independent activist in the late period of Joseon Dynasty, has a view of education similar to Plato's. He emphasized the importance of education on martial art in order to restore the our people's inner quality, 'Mind(心)'. Both Plato and Park Eun-sik thoughts that the education of physical training and martial art was the premise of study to make the humanity they pursued. And they expected that the talented people raised through the curriculum proposed by them would lead the prosperity of the nation by fulfilling their respective roles in society. In conclusion, from the view of Plato and Park Eun-sik's thoughts, it can be said that, the education of physical training and martial art for students is the premise of the study for personal perfection of human beings, and essential curriculum for making the ideal state that they dreamed.

'Private Garden', is a legal concept that encourages the opening of private gardens to the public. Twenty-five private gardens have registered with the Forest Service since the 2015 policy was enacted. Although it is a positive system in terms of spreading and encouraging garden culture, the exact nature, role, and designation requirements have not been fully discussed. The purpose of this study is to analyze the characteristics of 25 private gardens in Korea. The results of the study noted that the southern region occupied a large part of the geographical distribution of the private gardens, which is due to the natural and climatic conditions, the policies of the local governments, and the discretion of public officials. In addition, the gardens are almost all made up of modern gardens; there was only one house garden from the Joseon Dynasty. The owners of the gardens range from their 50s to 80s in age. The gardens were started because the owner believed it was a good endeavor, but many owners felt that it was difficult to manage the enlarged garden and eventually opened it through as a Private Garden in anticipation of receiving economic support. There are also owners who are willing to revitalize the area. In addition, profits are generated from facilities other than the gardens, and some operate related programs to promote the culture of gardening. For a sustainable Private Garden system, it is necessary to check the registration criteria and establish a clear role in the region. There is also a need for further measures for management and marketing. This study is meaningful as basic research on the Private Garden system that is not yet systematic.

The Jangsan Quartzite of the Joseon Supergroup and the foliated granite (so-called granitlc gneiss of presumed Precambrian age) of the Yeongnam massif are in direct contact at Cheondong-ri area, 6 km @SE of Danyang. sllthough it has been thought traditionally that the Jangsan Quartzite overlies unconformably the f&ted granite, it is difficult to interpret the contact as an unconformity smce the basal conglomerate in- the lower part of the Jangsan Quartzite does not have any clast of the foliated granite, Rather, recent structural studies of this area indlcate that the contact is a ductile shear zone. However, the sense and age of the shear movement are still problematic. Our mesoscopic and microscopic studies of &tre Cheondong-11 semi-brittle shear zone involving foliated cataclasite and phyllonite, which is a pa& of the Ogdong fault, indlcate a top-to-the northeast shearing, i.e., dextral strike slip. We also performed Pb-Pb dating for the age-unknown foliated granite, since the age of deformed granite ccarr emtrain the maximum age of deformation. The whole rock and feldspar Pb isotape data for the foliated granite and a micaceous xenolith define an isoc chron age of $2.16{\pm}0.15$ Ga ($2{\sigma}$;MSWD=4.4) which is interpreted as the emplacement age of the granite. This early Proterozoic age agrees with those of Precambrian igneous activity In the Yeongnam massif reported previously. The obtaiPrfid gge confirms the traditional idea about the age of the foliated granite and indicates that other methd(s) should be employed to constrain the age of the shear movement.

We collected Seokganju minerals (regions in Gyeryong Mountain, Sangsin-ri, Banpo-myeon, Gongju Chungcheongnam-province), which were used as natural color pigments for grayish-blue during the 15th~16th centuries of the Joseon era, and investigated their crystallographic features to develop a black pigment having a spinel structure. By a Raman analysis, the color of Seokganju under transparent glaze as a pigment for painting was black because hematite ($Fe_2O_3$) in Seokganju was converted to magnetite ($Fe_3O_4$) However, Seokganju into the transparent glaze as a pigment was brown because of hematite ($Fe_2O_3$) and small amounts of maghemite (${\gamma}-Fe_2O_3$) in Seokganju minerals. Only Seokganju mineral is used, it is not suitable for black pigment into the transparent glaze. This study tried to develop a spinel crystal black pigment stabilized by Seokganju with CoO, $Cr_2O_3$, NiO, and $MnO_2$ at $1280^{\circ}C$. A Raman spectroscopy analysis was performed to verify the presence of Mn The results showed that it existed as spinel, and two crystal phases $CoFe_2O_4$ and $MnFe_2O_4$ were mixed. $CoFe_2O_4$ spinel has a dark grayish black color and $MnFe_2O_4$ spinel has a greenish black color, and these two appeared as black. The color of a specimen calcined by adding 6 wt% of pigment mixed with 5 wt% of $MnO_2$ added to lime glaze was analyzed with a UV spectrophotometer. When applying the color pigment, it appeared black stabilized with $L^*$24.23, $a^*$ 0.12, $b^*$ -2.29 at $1260^{\circ}C$ oxidative calcination, With $1240^{\circ}C$ reduction firing, it is appeared black stabilized with low brightness of $L^*$ 23.13, $a^*$ -1.12, $b^*$ 0.54.

This paper aim to review the extent of Park Je-Ga's geographical interest and knowledge and where he intended to make good use of them through Bukhakui(北學議). In particular, it was classified and interpreted as the contents related to agricultural, industrial and commercial geography focusing on the contents of the economic geography. As for the contents related to agricultural geography, it suggests minutely and precisely the necessity and concrete methodology for farmland, seeding, fertilization, breeding of cattle, sericulture and fruits. As for the contents related to industrial geography, it lays emphasis on the pursuit of the modernization of ours by means of accepting high-tech, industrial engineering and knowledge from Western scholars who were staying in Beijing. As for the contents related to commercial geography, it puts emphasis on the conversion of idle labor capacity of the nobility to practical production capacity, the pursuit of economic vitalization by opening land transportation through wheels and the trade by sea with neighboring countries such as Qing, Japan, Ryukyu, Vietnam and so on. It can be known through this study that Park Je-Ga was a realist who made an effort to raise the economic power of the region and the country with using his endeavor of economic geographical interest and knowledge. His economic geographical interest and knowledge were connected directly with practical use. If his economic geographical knowledge and way of thinking had been accepted successfully at that time, the economic power in the latter half of the Joseon dynasty could have leaped to a considerable degree.

Jangan-eup, located in Busan, South Korea,is a famous pottery-producing area in the Joseon Dynasty period. The aim of this paper was to determine the correlation of the pottery from each kiln site of Jangan-eup by analyzing the ingredients of clay as well as its production technique and firing condition. The materials that were used for the study were fragments of inlaid celadon, white porcelain, and white porcelain painted with underglazed iron excavated from six kiln sites of Jangan-eup:Sil-li, Daeryong-li, Hajangan-li, Sangjangan-li, Yongso-li, and Dumyeong-li. In each of the samples from the six kilns, cristobalite, mullite, and quats were found. The firing temperature distinguished from the crystal structure was higher in the following order: Dumyeongli>Sangjangan-li>Daeryong-li>Hajangan-li>Yongso-li>Sil-li. The samples were divided into four groups based on the ingredients of the clayfound therein: the Sil-li andDaeryong-li group, the Hajangan-li and Sangjangan-li group, the Yongso-li group, and the Dumyeong-li group. It was also found that the sample of Dumyeong-li was made using the most homogeneous clay compared with the other samples. The pottery of Jangan-eup had $40-400{\mu}m$ glaze, had bubbles in their bodies, and had $10-150{\mu}m$ sizes.

Korean studies are in crisis because they have fallen prey to the territorial trap associated with methodological territorialism and methodological nationalism. In order to overcome this situation, this paper suggests the studies on Korea to be more active in accepting the socio-spatial perspective that emphasize the inseparability of society and space. In particular, paying special attention to the 4 important dimensions of socio-spatial relations, such as place, territory, network and scale, it examines the ways in which these 4 dimensions are overlapped, interconnected and dynamically interacting with one another from the perspective of "multi-scalar networked territoriality". In conclusion, I argue that the Korean studies need to understand the variegated and multi-scalar nature of Korea, a place, which is constituted through complex interactions among diverse political, social, economic and cultural forces and processes that operate in various places and at diverse geographical scales.those days, such as agriculture, crops, and transportation of goods. Fifth, the bibliography and citations explaining all instances reveal that China (Qing) is a great civilization of the advanced world and that the scholarship of Joseon relied on and accepted it. Sixth, except for horse raising and management, farming implements for rice transplantation, sericulture, and natural dying of cloth, most of the topics are useful even today. In short, theres is a profound aspect to the content that makes it possible to estimate the "geographical thinking". In general, the focus of the content of this book directly linked to the practical agricultural economy of the common people.

The present study investigates the realization of tourism culture welfare by using Confucian heritage. From June 13 to November 7, 2014, site surveys and interviews were conducted for hyanggo (hyanggo: Confucian temple and school to teach students in Joseon Dynasty period), seowon (seowon: a memorial hall for Confucianist services to honor distinguished scholars and statesmen) and nujung (nujung: outdoor pavilion or gazebo) located in Youngwol -gun. Questionnaire pertaining to site survey and in-depth interviews for the building owners and managers was used to collect necessary data and scientific investigation was performed for analysis. As a result, the historical background was found to be culturally valuable asset for both region's tourism and culture welfare. Secondly, hyanggyo and seowon were found to exhibit traditional Confucius cultural form, while nujung exhibited a rare architectural trait. Hence it seems necessary to develop a different social tourism resource specialized for nujung. Thirdly, the rendering of Confucius heritages to tourism culture welfare resources thus far seems to be insufficient; hence, development and operation of marketing programs will be necessary. The implications of the present study require succession and modern reinterpretation of Confucian heritages for further development into digital tourism that will encompass Confucian culture and today's culture. Furthermore, studies of the tourism culture welfare policies that will promote the co-existence with the region will be needed.
