Palaces of a country can be representative aggregate of the culture and arts of the country. Palaces were used not only as a living place to protect kings and royal families and to live cultural lives, but also a political place to govern the country. Kings in Choseon founded the country on the Sung Confucianism, their philosophical background. They built Bangji and Wondo as constant reminders of their philosophy. Bangji is the most apparent characteristic in the palace gardens of the Choseon Dynasty. Finding out the original form of Jidang, restoring the original and passing it on to future generations can be passing on the spiritual culture of our ancestors. This study is done to find out or locate well preserved Jidang, transformed Jidang and lost Jidang in Changdeokgung, which is the best conserved palace of Choseon. This study is composed of Jidang which has been kept in its original state, transformed Jidang, locating lost Jidang and Jidnang which has been unearthed. The total number of Donggwoldo's Jidangs is 17; those that are kept in their original state, 4; transformed Jidangs, 5; Jidangs that were lost and have been located, 8; and newly appeared Jidangs, 2. From the results, opinions on restoration are presented. This study can be a small drop in the thin stream of tradition passing onto future generations in this world where knowledge and information are transported momentarily and the classification of culture and border is mixed, yielding vagueness.

The purpose of the present study is to clarify the process of change to the pond at the Jongmyo Shrine(宗廟), from the Joseon Dynasty period to the modern and contemporary era. The consequent research results can be summarized as follows. The first record of the Jongmyo pond is confirmed in the "Annals of King Sejong(世宗實錄)". The pond, which was being constructed at the time, refers to the current upper pond(上池). A pair of islets(雙島) were constructed during the Sukjong(肅宗) period, with several trees planted on the middle islet(中池). The middle pond is thick with lotuses. In particular, the middle island on the middle pond subsequently changed into a single island(單島), which is likely to be related to the pond expansion during the reign of Youngjo(英祖). When the lower pond(下池), involving dualistic arrangement, was constructed in the modern and contemporary era, the pond of the Jongmyo Shrine underwent a drastic transformation phase. The lower pond was constructed before 1947 at the latest, and when the right side of the lower pond was filled in the mid 1980s, the dualistically arranged lower pond became a unified type of lower pond. On the other hand, the bank protections of the upper and middle ponds were constructed with earth, but was subsequently modified into its current form using stone.

This study was carried out to find the changed contents and details of the ponds at Jondeokjeong area in the Changdeok Palace, where was modified during the reign of King Gojong(高宗, 1863~1907), and considered the internal context through the diachronic views about royal garden building in the Joseon Dynasty. The results were as belows. First, this study found that the transformed time of the ponds at Jondeokjeong area was the 21th year of King Gojong(1884) based on the pictures taken in the last half of the 19th century and the records of "Gojongsilrok(高宗實錄: Annals of the King Gojong)". Second, this study also found that the remodeled ponds at Jondeokjeong area by King Gojong were followed the landscape of Geoncheong Palace(乾淸宮) and Hiangwon-pond(香遠池) in Gyeongbok Palace because the remodeled ponds of Jondeokjeong area had the spatial organization similar to Hiangwon-pond. Third, the bridge of remodeled ponds at Jondeokjeong area was utilized as the expedient to expand the function of rear garden, which combines the areas of Yungyungdang(演慶堂) and Jondeokjeong. This was the same method that Konchunggung(乾淸宮) in Gyeongbok Palace had occupied the whole area through the Chui-hiang bridge(醉香橋) which connects to the Hiangwonjeong(香遠亭). Fourth, ponds at Jondeokjeong area and Hiangwonjeong that were created during the year of King Gojong promised the use of Yungyungdang and Konchung Palace, and reflected the statuses of the two building-blocks. Lastly, this study concluded the remodeled Jondeokjeong ponds were not only to create the necessary spaces of the landscape for King Gojong, but also to build the space on the context of Huwonjeongdang(後苑政堂: political structure in rear garden), which has been passed down from their ancestors.

This study sheds light on a pond design process which is a core facility of Hwaseol-dang in Muan, the Jeonnam. The plasticity of the pond was analyzed and interpreted for the design process using methods such as "literature search, interview, site visits, aerial pictures, aerial photographing, drawing figures of configuration plane via measurements, internet search, etc.", to trace the developing process of the design and the implications therein. The study results being centered on the developing process of the pond design are summarized herein below. The position of the Hwaseol-dang, being formed on a low hill having low competence as a place for a pavilion, draws more attention regarding its implications from the aspect of inner design. The pond Hwaseol-dang is in a rectangular shape of 1 : 1.2 ratio, in which the depth is a bit higher on the pond edge of the Hwaseol-dang thus being slanted, and Crape Myrtle, which is not known whether introduced during the formation of the pond, is cultivated on the island in the center widespread toward the southeast region. The planar design of the pond is interpreted as "rectangular pond" but it has a smooth half-moon shape where a part is excluded to remove edge. In particular, the three islands in rectangular pond, due to the narrow area, put one island and two half-moon-shaped islands in juxtaposition, and thus, although only being one island, resultantly exhibits the existence effect of proliferated three islands. This is allegedly due to the intentional formation aiming at the effect of hybrid while minimizing the overlap due to merging and adding from the aspect of constituting a design. Furthermore, the pond Hwaseol-dang is extended northwest along with Hwaseol-dang, and also the island in the center is thought to additionally have one or two, but the widespread phenomenon of the island in the center appears to consider the effect of "sit view on the floor of the pavilion of Hwaseol-dang". Considering that even a few examples of ponds having the three islands among the private house gardens in the nation are all curved ponds, the characteristics of the rectangular Hwaseol-dang pond establishing the garden effect of the three islands by modifying the one island in rectangular pond is highly notable. Considering that the three islands of "Yeongju, Bangjang, and Bongrae" is the original shape of the pond garden gestating Taoist ideology, as a symbolic design of a pond, it is regarded as the characteristics of the pond shape in Jeonnam area, and the so-called three treasures "Hwaseol-dang, Camellia, and oddly shaped stones, etc." are concentrated as the symbolism of Hwaseol-dang pond.

This study was conducted to investigate the variation of fruit and seed morphology among populations and among individuals within population of Sorbus commixta Hedl. distributed in Korea. Fruits collected from 42 trees in six natural populations and their six fruit and four seed characteristics were analyzed. In all characteristics, there were significant differences among populations and among individuals within populations. Especially, number of fruits per fruit-bearing branch and number of seeds per fruit showed higher values among populations in total variance component. Coefficients of variation in the number of fruits per fruit-bearing branch and seed weight are relatively high (42.0~75.3%) compared to other traits (11.9~32.1%). As a result of simple correlation analysis, the number of fruits per fruit-bearing branch showed a significant positive correlation with latitude but showed a negative correlation with longitude. According to cluster analysis, geographically close populations showed the tendency of clustering into the same group. Three principal components (PC) were deduced from principal component analysis, which explain the 87% of total variance of fruit and seed characteristics. The highest contribution was seed length and seed weight in PC1, fruit width and seed index in PC2 and fruit length and number of fruits per fruit-bearing branch in PC3.

This study explores mime elements of court Hagmu(鶴舞) in literature and what is expressed in the practice of current Hagmu and examines what has been changed while others are kept intact. The content of Hagmu is that "attracted by lotus flowers in a pond, cranes dance around and peck at them, when the blossoms open wide with a girl [dancer] inside, upon which the surprised cranes fly away." The dance consists of 4 steps: the first step is for the entrance of cranes; in the second step the cranes dance moving across jidang(池塘) and the north; in the third step the cranes are curious about the lotus calyces, yeontong(蓮筒); and the cranes withdraw in the fourth step. The literature suggests that the dancing courses on the stage are limited to the east, the west, the south, and the north. The movement is limited to naeson (內旋) only in mujin(舞進) and mutoe(舞退). Furthermore, the gaze is only allowed toward the north and jidang. Motions are limited to naejog(內足), oego (外顧), and naego(內顧). However, the mime elements of current Hagmu are attributed to the effort of translating crane's life into a realistic story. It relates the life of cranes to that of human beings and implies love in it. Finally, the court Hagmu has entered the real world out of the literature, enriched with new elements. Under the transition from literature to practice the diversity of expression is added while the elements related with court codes such as courses, movements, directions, and motions are kept intact. These limitations, however, are coupled with the sensitive 'love' and the exposure of dancing instruments intrigues audience and creates dramatic effect. In conclusion the significance of mime elements in court Hagmu is in enhancing communication with audience.

Ijidang(二止堂) is a private village school (seodang, 書堂) established in Okcheon, north Chungcheong province where Jungbong Jo, Heon(重峯 趙憲, 1544-1592 AD) had trained for his sound mind and body(yusangcheo, 遊賞處). Jo, Heon was a notable Neo-Confucian scholar of the Kiho School and also a righteous general leading soldiers in Joseon Dynasty. According to Ijidanggi(二止堂記), Ijidang was constructed to honor Jo, Heon and to train local talents in 1647 with the support of Song, Si-yeol(宋時烈, 1607-1689 AD),a representative scholar belong to Kiho School and other local Confucian scholars. Ijidang currently consists of Main Body(本體) in the middle along with the East(Dong-lu 東樓) and the West Pavilions(Seo-lu 西樓) attached to each side. The Main Body and the Dong-lu firstly constructed were to give lectures and to rest within. Ijidang has undergone several changes in its form so far. The surrounding nearby Ijidang shows characteristics of the Confucian architecture for training(J eong-sa, 精舍) and the building itself was to be built in a scenic place apart from the secular world in which scholars stayed, cultivated their body and mind or taught disciples within. The lecture space of Ijidang is positioned next to the main hall(Dae-cheong 大廳) unlike other typical forms of a three-bay building(samganjije 三間之制) at that period. West lu, a two-story building added afterwards in the early 18th century representing characteristics of the Gate Pavilion(Mullu, 門樓) of Neo-Confucian Academies(Seo-won, 書院) in Joseon Dynasty was typically located where the entrance and the ground floor of the main building are visible simultaneously.

Strobilus initiation in grafted, 18-year-old slash pine (Pinus elliottii var. elliottii) in a seed orchard was examined in relation to morphological and anatomical characteristics of shoots. Needle weight (total fresh weight of needles per shoot produced during the current growing season) was the most closely related single variable to the number of female flowers produced the following year ($R^2=0.41$). The number of female and male strobili (per shoot) produced the following year was positively and negatively correlated, respectively, with the total weight of current-year needles per shoot. A transition from male to female flowering was associated with increasing vigor (number of needles) of the shoot. Vegetative buds in the upper parts of the crown of poor-flowering trees showed more advanced growth of vascular tissues compared with female-or male-producing buds, indicating a strong favor for vegetative growth.

In this paper, we propose an efficient multicasting algorithm in multistage interconnection networks (MIN's) employing the region encoding scheme. The proposed algorithm uses the recursive scheme to recycle a multicast message at most two times through MIN, in order to send it to its desired destinations. It is composed of two recycling phases which are the copying phase and the routing phase of the multicast message. In the first phase, a source sends the message to a region that contains the largest number of destination regions, and destinations in these regions receive and store the message in this phase. The remaining destinations can finally receive the message in the second phase. This method of the algorithm can improve its performance by reducing the delay of message and the volume of traffic. Moreover, we evaluate the performance of our algorithm in terms of the average number of recycling and the number of internal links used per destination, comparing with the previously proposed algorithm.

Through literature review and on-site survey of Gimcheon Bangcho pavilion(芳草亭), the features of garden design(庭園意匠) including geographic conditions, landscape modeling of Nujeong(樓亭) and Jidang(池塘, Pond), and scenic interpretations in Nujeong Jeiyoung poetry(樓亭題詠詩) have been carefully researched and the findings are presented below. Bangcho pavilion is located in a village called Wonteomaeul, which belongs to the feng shui state of golden hairpin and floating lotus. It has long been the cultural hub of communication and social interactions among the villagers. The Head House of Jeongyanggong(靖襄公宗宅), the main house(本第) of the Yeonan Yi Clan(延安李氏), is about 150m away from Bangcho pavilion, an artistic space whose landscape modeling is of the form called Nujeong. The name 'Bangcho' reflects the noble man(君子)'s determination: "I yearn for the place where honey parrots fly and the fragrant grass grow." From the two story structure of the pavilion where there is an additional floor installed to the central ondol room by a four-sided subdivision door, one can detect the aspiration of the men for pursuing an open view. One can also observe the efforts in designing the room to be used for multiple purposes from a private place to an office for periodic publication of a family lineage document called "Garyejunghae(家禮增解)". Bangcho pavilion's main sight of interest is Mrs Choi's Pond(崔氏潭), the one and only garden structure that comprises the twin round island of square pond(方池雙圓島) among the existing Jidangs in Korea. In this special Jidang, there are two coexisting islands that represent a well thought out garden facility for symbolizing conjugal affection and unyielding fidelity between master and servent(主從). In addition, the three inflows and one outflow facing the Ramcheon valley is regarded as an ideal garden design optimized for performing the function of a village bangjuk which is the site for undercurrent creation and ecological reprocessing. At present, Giant pussy willow is the only circular vegetation identified in the area of Bangcho pavilion, although this plant species is about to wither away judging from the signs of decrepitude that seems to persist for two out of three weeks. The old pine tree that appears in the 1872 Jeiyoung poetry of Byeongseon Song(宋秉璿) no longer exists. Anjae(安齋) Jang Yoo(張瑠)'s "Eight Scenary on Bangcho pavilion(芳草亭八詠)" and its expansive reproduction "Ten Scenary on Bangcho pavilion(芳草亭十景)" from Gwagang(守岡) Lee Manyoung(李晩永) depict vividly the pastoric scenery of an idyll(田園景) that stretches throughout the natural and cultural landscape of the province of Gimcheon and Guseong surrounding the Bangcho pavilion. The Bangcho pavilion sutra aims to establish Bangcho pavilion and the village of Wonteomaeul as the centre of microcosmos by dividing and allocating its scenic features according to the four seasons and times(四季四時), the eight courses(八方) and the meteorological phenomena, and it is the incarnation(顯現) of landscape perception upon the Byeol-seo Scenic site of Bangcho pavilion, the cultural hub of the region.
