  • Nondestructive methods to check the vitality of trees and to find out internal decay of old-giant trees include the use of electrical resistance, ultrasound transmission time, microdrilling, and infrared thermography etc. Among these, ultrasound transmission offers some advantages compared to others such as it is an entirely nondestructive detection method and it can be applied to very big trees. However, the ultrasound equipment is comparatively expensive and not broadly spread yet. On the other hand, Shigometer is versatile to be applied to check vitality of the tree and find out internal decay. Electrical conductivity of plant tissues is a very useful characteristics to determine the vitality and internal decay of trees. Electrical resistance of cambial area tells about the vitality of a tree and electrical resistance of heartwood reveals discoloration or decay of it. For determination of the vitality of the tree, the standard equation for calibration of measured electrical resistances should be developed by measuring and analyzing electrical resistance from at least 30-40 trees of the same species with that tree. All the factors, especially tree species, diameter of the stem, and temperature, which can altered the electrical resistance of trees, should be taken into consideration in the development of the equation. If the standard equation is developed for old-giant trees that we should conserve, it will be very useful. In addition, periodical and continued measuring of a certain tree will help to determine the condition of the tree by comparing the measurement with accumulated data of the tree. Measuring electrical resistance of wood might not require the standard equation. But it also needs to check electrical resistance of sound wood of the same tree species. If the stems that should be examined is thicker than 40cm, it is better to use the ultrasound measurement combined to Shigometer.

  • This study was performed in 2010 to examine the flora and vegetation structure and chemical characteristics of soil in the growing community of Abeliophyllum distichum, located in the Byeonsanbando National Park. This Abeliophyllum distichum community has more individual numbers in Cheongrim-ni and Jungkye-ri, Byeonsan-myeon, and Buan-gun area, which is designated as a Natural Monument (No. 370), and also where the habitat conditions for Abeliophyllum distichum is more favorable. The authors recorded 100 taxa with 45 families, 82 genus, 93 species, 4 varieties, and 3 forms. Among them, species such as Abeliophyllum distichum (critically endangered), Asarum maculatum (near threatened) and Chionanthus retusa (near threatened), which are categorized as rare plants, were recorded. According to the list of Korean endemic plants, 4 taxa, particularly Philadelphus schrenckii, Abeliophyllum distichum, Weigela subsessilis, and Lonicera subsessili, were recorded. The community of Abeliophyllum distichum is located in the northwest slope of Baekcheon watershed and the community is comprised of healthy soil. The community structure was classified into three: the Castanea crenata community, Zelkova serrata community, and Quercus serrata community. The Castanea crenata community is composed of the Cornus walteri, Platycarya strobilacea, Zelkova serrata, Rhamnella frangulioides, arranged in terms of importance percentage. The Zelkova serrata community is composed of Celtis sinensis, Quercus aliena, Styrax japonica, and Acer pseudo-sieboldianum, also according to importance percentage. As for the Quercus serrata community, it is composed of Quercus variabilis, Castanea crenata, and Prunus sargentii, also arranged in terms of importance percentage. The importance percentage of Abeliophyllum distichum is 6.6% in the Castanea crenata community, 5.6% in the Zelkova serrata community and 5.1% in the Quercus serrata community. Moreover, in order of chemical characteristics of soil pH, electrical conductivity, available phosphoric, organic matter, and exchangeable cation (K, Ca, Mg) are analyzed. The No. 3 site was relatively higher than other districts of the same chemical characteristics of soil.

  • Danggol, in other words the hereditary shaman, is a person who is performing the Gut(the Korean shamanistic ritual) as the job but fortuneteller simply tells someone's fortunes. Nowadays most of fortunetellers think their works are wholly managed the Gut as the holy jobs. But Generally this kinds of jobs, we think it is lower than ordinary people's level of education in the korea. Actually we can meet eleven fortunetellers who have a college diploma out of them, so we can know that their education's level is increasing gradually. On the other hand a house of fortunetellers is the place where can lead the way of our lives in the method of seeing one's past life or making predictions of someone's coming events etc. Gradually this place seems to be separated with a private home, so the most of them is managing as the monthly rent. Consequently this houses are heavily located at the Gyerim five-way crossing, the Yang-dong Dakjeonmeory street, Jungheung-dong local culture street area. Each fortunetellers have the different ways of fortune-telling because this methods are decided by their one's characters. So their fortune-telling time and its time required for a task is far different. The methods of telling it is very much different in accordance with the learning fortuneteller or spiritualistic fortuneteller. But the process of fortune-telling is common like as a preparatory stage, carrying a Jumsa(fortune-telling) stage and acting by a Jumsa stage. These steps are sequential but linked together. There are six special features of fortune-telling culture in Gwang-Ju. 1. The role of a fortuneteller and Bosal(spirit-descended shaman) runs at the same time. 2. The house of fortune-telling is doing Gutdang(ritual house)'s works. 3. Its location are heavily collectivized at the specific districts. 4. The learning fortuneteller are increasing gradually. 5. The youth are growing use in the fortune-telling house. 6. There are many person that are visiting this house because of individual problems not their family's problems.

  • Maehwa blossom(梅花) has been favoured in literary and artistic works in the East Asia as one of representing symbols of virtuous men's character. Maehwaseookdo(梅花書屋圖) is one of major forms of painting. This paper starts from the birth of Maehwaseookdo since it aims to examine the following points: its structural origin of the Gurimaehwachonsado(九里梅花村舍圖) style; how this style was distributed in Korea; process and features of Maegamdo(梅龕圖). The current academic world admits Maehwaseookdo is originated from an ancient story of Lim Po(林逋). Even though Maehwaseookdo and Lim Po story can be linked to a meaning of schoarly hermitage, ways to structure works are hard to compare paintings based on Lim Po story. While paintings related to Limpo story such as Banghakdo(放鶴圖) and Gwanmaedo(觀梅圖) depict a scholar(s) and a few Maehwa trees with cranes, Maehwaseookdo presents scholarly hermitage with a lot of Maehwa trees which encircle a house building. As other paintings related to Maehwa blossom were widely painted since the nationwide popularity of the theme of Maehwa, Maehwaseookdo was not drown throughout the whole period of time. Since Goryeo, Maehwa paintings including Sehansamu(歲寒三友), ordinary Maehwado as one of the Four Gentlemen's plants, and Tammaedo(探梅圖) which was based on ancient anecdote of Maeng Hoyeon. Maehwaseookdo, however, was created exclusively in the 19th century. In China a similar feature took place much earlier period which was in the 17th century. Accordingly we can assume that these patterns which paintings in particular styles were generated by particular cultural phenomena. The reason why Joseon's Maehwaseookdo works were painted exclusively in the 19th century was that Kim Jeonghee's party and Sin wi had acquaintanceship with Jang Sim(張深) who got work orders for Oh Sungyang(吳嵩梁). In these corresponding activities, two types of Maehwa paintings were exchanged. In China, scholars usually drew paintings in the type of Gurimaehwachonsado(九里梅花村舍圖) depicting scenic views of Guriju(九里洲) which was riverside area under the Mt. Buchun(富春山). This place surrounded by thousands and hundreds of Maehwa trees was where Oh Sungyang(吳嵩梁) was about to retire to hermitage in. In this repect, Joseon scholars painted Maegamdo(梅龕圖) depicting a scene of a shrine with Oh Sungyang(吳嵩梁)'s poetry books surrounded by Maehwa trees for paying tribute to the wall of Maehwa trees(Maebyeok(梅癖)). This seems to adapt the format of 'Manmae(萬梅)' which appeared in the type of Gurimaehwachonsado. One of the representing works of this, is painted or supervised by Sinwi. Paintings in two types with respective meanings were combined by which was estimated to be painted by Sin Wi, then it became a structural base of by Jang Sim(張深) This type of Maegamdo brought the popularity of Maewhoseookdo which once had another name of 'Manmaeseookdo(萬梅書屋圖)' by a group of scholars such as Jo Heeyong, in the 19th century. All things considered, this paper can be a sort of precedent phrase to find out the birth of Manmaeseookdo which was very popular in the late 19th century.

  • The purpose of this study was to analyze the current status of both exotic and naturalized plants in the designated Cultural Preservation Area located in Seongju-gun, Gyeongsangbuk-do in order to identify traditional cultural places and to provide basic information to prepare a conservation strategy. The vascular plant species was identified as having 114 taxa: 50 families, 93 genera, 94 species, 16 varieties and 4 forms in King Sejong's Prince Taesil. Among them are 15 taxa of the exotic plant species and 16 taxa of naturalized plant species, which resulted in 14.04% of the Naturalization Rate and 5.90% of the Urbanization Index. The vascular plant species was identified as 68 taxa: 40 families, 64 genus, 57 species, 8 varieties and 4 forms in the Seongju Hyanggyo. Among them, the exotic plants recorded 17 taxa with 30 taxa of naturalized plants. The Naturalization Rate was 44.12% and Urbanization Index was 11.07%. The Seongbaksup, which was a grove outside of the Seongju Fortress recorded 61 taxa: 34 families, 58 genera, 55 species, 5 varieties and 1 form. Among them, the exotic plant species consisted of 10 taxa with 17 taxa of naturalized plants, with a 27.87% Naturalization Rate and a 6.27% Urbanization Index. The vascular plant species was recorded as 230 taxa: 92 families, 183 genus, 182 species, 1 subspecies, 32 varieties and 14 forms in Hangae Village. Among them, exotic plants consist of 28 taxa with 85 naturalized plant species, with a Naturalization Rate of 37.12% and Urbanization Index of 31.37%. The vascular plant species in the Seongsan Ancient Tomb is recorded as having 131 taxa: 55 families, 107 genus, 106 species 19 varieties and 6 forms. Among them, exotic plants consist of 18 classifications, and naturalized plants consist of 22 classifications with a Naturalization Rate of 16.79% and an Urbanization Index of 8.12%. The Seongju Hangyo recorded the highest Naturalization Rate among all surveyed sites in Hangae Village. All five of these surveyed sites will require a management plan to eradicate both exotic and naturalized plant species. Hangae Village especially needs to prepare a management plan. The invasion of ragweed in Seongju Hanggyo and Hangae Village, which is one of the most invasive plant species to disturb the ecosystem, is in need of management to eradicate it.

A Study of the Transmission of Community Religion in Seoul Focussing on the Shrine of the Authorities and the Change (서울지역 공동체신앙 전승과정 고찰 조선시대 각사(各司) 신당(神堂)의 존재양상과 변화를 중심으로)

  • Seoul's community beliefs originated from the ritual performed by the shrines affiliated to each government office in the Joseon Dynasty. Lower branches of government officials were assigned to perform these rituals. Generally, these shrines were called Bugundang(府君堂). Records show that Bugundang(府君堂) was generally one to three units and enshrined the portrait of Bugun(府君), the worshipped, inside. According to historical records, the worshipped were mostly General Choi Young(崔瑩將軍) or Madame Song(宋氏夫人). In fact, however, each Bugundang(府君堂) worshipped different persons. Some of the worshipped were historical characters from the Goryeo Dynasty or the founding period of Joseon Dynasty, Guan Yu(關羽) and Zhuge Liang(諸葛孔明) that became gods after the Japanese Invasion of 1952, Wanggun(王建), Dangun(檀君), General Nam Yi(南怡將軍), Kim Yoo Shin(金庾信), Lim Gyeong Up (林慶業), King Gongmin(恭愍王), King Taejo(Lee Sung Gye, 太祖 李成桂), Joban(趙?) who is one of the supporters of the foundation of Joseon Dynasty, Sir Hong(洪氏大監) and his women who appear in the legend of Nanhansanseong(南漢山城) area, and many other historical figures. It is difficult to compare the rituals of these shrines from community Gut(Shaman ritual) performances of Seoul. According to historical records, Gut and ceremony coexisted in rituals. As time passed, these rituals spread as the community Beliefs of commoners and have been transmitted in the context of Seoul's cultural change. This study examined the existence of affiliated shrines of local government offices in the Joseon Dynasty and discussed the cases of Jangchung-dong Gwanseong Shrine(將忠洞 關聖廟), Bangsan-dong Seongje Shrine(方山洞 聖帝廟), and Seobinggo Bugundang(西氷庫 府君堂) to trace the succession of rituals at these shrines as folk customs of commoners. Bangsan-dong Seongje Shrine(方山洞 聖帝廟) spread to the public as Gwanwoo(關羽), who was considered the god of soldiers, transformed into the god of merchants along with historical transition. It clearly shows the process as to how merchants from a certain region developed a community religion. Jangchung-dong Gwanseong Shrine(將忠洞 關聖廟) is Bugundang(府君堂) of the soldiers of Nampyoug(南營). As the ritual was succeeded by a ritual group called Yeoungsinsa(永信社), composed of nearby residents, it was naturally spread and succeeded by the residents in local community. Seobinggo Bugundang(西氷庫 府君堂) was related to the changes in the historical background of ice gathering in the late Joseon Dynasty.

  • This study analyzed vegetation structure of natural monuments Koelreuteria paniculata community in search of a conservation and management plan. Plant sociological analysis of Koelreuteria paniculata community indicates that it can be classified into Achyranthes japonica subcommunity and Rhodotypos scandens subcommunity and Trachelospermum asiaticum var. intermedium subcommunity. While Koelreuteria paniculata community of Ahnmyeondo is composed of sub tree layer and herb layer, those of Pohang and Wando are composed of tree layer, Sub tree layer, shrub layer, herb layer. The results of tree vitality analysis showed that those in Ahnmyeondo appeared to be relatively low when compared to those in Pohang and Wando-gun. This can be understood in two different aspects: disease and insects vulnerability due to a relatively simple structure and lack of competitive species, and decreased vitality / natural branch losses due to crown competition arising from high density. The result of soil characteristics analysis showed that soil texture, soil pH, organic matter, $p_2O_5$, exchange positive ion were sufficient for tree growth while total nitrogen was not, so that discretion would be needed for fertilizer application. As there were damages of disease and inscet, but only for 10~15% of the entire area; it still requires consistent preconsideration. The study suggests the management methods for preservation of Koelreuteria paniculata community. First, securing designated areas is necessary in order to minimize environment deterioration due to surrounding development. Especially, for sections with decreased areas, expansion of designated areas through land purchase should also be considered. Second, artificial interference may affect the livestock. Therefore, monitoring of artificial interference is necessary, based on which protection projects must be conducted. Third, from analysis of young plants which influence the maintenance mechanisms of Koelreuteria paniculata community, a decrease compared to the prior year was observed; investigation is needed. Therefore, an active management policy through status examination of livestock such as germination and young plants is necessary.

  • It can be observed that steep slopes ($65^{\circ}$ to $80^{\circ}$) consist of rock masses were kept stable for a long time. In rock-mass slopes with similar ground condition, steeper slopes than 1 : 0.5 ($63^{\circ}$) may be applied if the discontinuities of rock-mass slope are distributed in a direction favorable to the stability of the slope. In making a decision the angle of the slope, if the preliminary rock mass conditions applicable to steep slope are quantitatively setup, they may be used as guidance in design practice. In this study, the above rock mass was defined as a good continuum rock mass and the quantitative setup criterion range was proposed using RMR, SMR and GSI classifications for the purpose of providing engineering standard for good continuum rock mass conditions. The methods of study are as follows. The stable slope at steep slopes ($65^{\circ}$ to $80^{\circ}$) for each rock type was selected as the study area, and RMR, SMR and GSI were classified to reflect the face mapping results. The results were reviewed by applying the calculated shear strength to the stable analysis of the current state of rock mass slope using the Hoek-Brown failure criterion. It is intended to verify the validity of the preliminary criterion as a rock mass condition that remains stable on a steep slope. Based on the analysis and review by the above research method, it was analyzed that a good continuum rock mass slope can be set to Basic RMR ${\geq}50$ (45 in sedimentary rock), GSI and SMR ${\geq}45$. The safety factor of the LEM is between Fs = 14.08 and 67.50 (average 32.9), and the displacement of the FEM is 0.13 to 0.64 mm (average 0.27 mm). This can be seen as a result of quantitative representation and verification of the stability of a good continuum rock mass slope that has been maintained stable for a long period of time with steep slopes ($65^{\circ}$ to $80^{\circ}$). The setup guideline for a good continuum rock mass slope will be able to establish a more detailed setup standard when the data are accumulated, and it is also a further study project. If stable even on steep slopes of 1 : 0.1 to 0.3, the upper limit of steep slopes is 1 : 0.3 with reference to the overseas design standards and report, thus giving the benefit of ensuring economic and eco-friendlyness. Also, the development of excavation technology and plantation technology and various eco-friendly slope design techniques will help overcome psychological anxiety and rapid weathering and relaxation due to steep slope construction.

  • The purpose of this study is to examine the effects of the transformational leadership on helping behaviors and deviant behaviors of organizational members and to verify the control effect of value consistency and to suggest a process for effective business management and human resource management. For this purpose, questionnaires were distributed to employees working in office management, area marketing, and manufacturing industries in Seoul, Gyeonggi and Chungcheong provinces, and the final 334 copies were used for empirical analysis. Data were analyzed using SPSS 18.0, and reliability analysis, factor analysis for validity, correlation analysis, and regression analysis were conducted to verify the research hypothesis. The results of the empirical analysis based on the questionnaire based on the object are as follows. First, charisma of transformational leadership showed negative impact on helping behavior, and intellectual stimulation of transformational leadership and individual care showed positive influence on helping behavior. Second, charisma of transformational leadership showed negative influence on deviant behavior, whereas intellectual stimulation of transformational leadership and sub - constitutional factor of individual care did not show significant influence on deviant behavior. Third, as a result of confirming the moderating role of transformational leadership and helping behavior on the level of value consistency, it showed moderating effects on charisma and individual consideration of transformational leadership. Through this study, we proved the effectiveness of transformative leadership which increases the helping behaviors of the members and reduces the deviant behavior. Based on this, we proposed the necessity of developing managers' transformational leadership improvement program to enhance the sustainability of the organization. And we confirmed the partial influence relationship on the adjustment effect of value consistency. In addition, negative influence of charisma suggests a significant point in the management process design.

  • A ritual ceremony accompanied by a song and dance is called as Kagura in Japan. The word Kagura is originally derived from Kamukura, which means the place where spirits reside. However, later it came to refer to the whole process of the ritual ceremony itself. Through the field studies, this paper examines Takachiho-kagura, helded in Takachiho, known as the village of myths, located in northern Miyazaki-ken in Japan. Kagura takes place all night through in each and every village in Takachiho and it normally runs from the end of November when the harvest season ends until early February the next year. One ordinary house is especially chosen for this ceremony, in which Kagura performs 33 repertoires. Takachiho-kagura is sometimes called as Yokagura, since the performance takes place over-night. A song and dance is performed by ordinary village people called hoshyadong, who inherited Takachiho-kagura. Currently, the ceremony is held in more than 20 villages and designated by the government as "Important Intangible Folk Cultural Property" in Japan. Takachiho-kagura follows the example of rituals held in Sada shrine in Izumo, which is now eastern Hiroshima-ken. It is the dance using a bell, a sword, a fan, which signify Norimono and is usually combined with mask-play called as Shinno. From the shrine of village, itwelcomes the gods who defense their village, called Ujikami and other 8 million gods, called Yaoyorozunokami, in Kagurayado, where Kagura of 33 repertoires is played in order. Kagura starts from dances for attendance of the gods, Hikomai, Daidono, Kamioroshi, performs dances of Amanoiwato, the gate of heaven's cave in Japanese myths, Dazikara, Uzume, Dotori, and continues dances for the old ghosts Shibahiki, Yatsubachi mixed with acrobatics. Finally, this performance ends with dances to send off the gods, Hinomae, Gurioroshi, Gumooroshi, until the dawn the next morning. This paper explores Takachiho-kagura from the perspective of folk performance with ethnography. These days, ecstasy and oracle do not happen in Takachiho-kagura. However, it kept the old form of folk performance as Kagura held in ordinary house. Especially, in Takachiho, remarkable venue of the Japanese myths, Takachiho-kagura is developed artistically. The first field study was held in Gokamura, Iwato-zone and Ashakabe, Mitai-zone between December 6th and December 12th 1997. Afterwards, the second field study was conducted in the area of Shiba and Ashakabe from December 17th until December 19th 1997 and from December 1st until December 10th 2000.
