This study was to understand the basic principles of the East Asian wooden structure system research and analysis. The Korea and China ancient architecture internal structure research that the combination of girders and crossbeams position. The ancient wooden structures of eastern Asian countries, Korea and China are not much different from each other in the principles of the wooden architecture structure, combining pillars, purlins and crossbeams. However, it seems that age-division, local-division, national-division differs in detail techniques. China ancient wooden structures combination of purlin and crossbeam, and So-seul Timber(Chinese name: Chashou叉手, Tuojiao 托脚) seems to show differences according to the age of the fulcrum position, detailed approach is also different according to various historical dynasty. Before in the 15th century, Purlin and Crossbeam are coupled to each other, but since the 15th century, seems to have developed a technique combined with each other Girder and Crossbeam and to prevent buckling of the Crossbeam cross-sectional area increased dramatically. For Tuojiao in China Tang-Wudai dynasty(A.D. 618~979), can see that saw the top position Girder and Tuojiao no direct coupling, can be seen as maintaining the safety of the material than the material of the inner wooden structures prevent buckling of the purlin. Korea ancient wooden structures of Goryeo dynasty(A.D. 918~1391), So-seul Timber(Chinese name Tuojiao) why do not to use the fashion? To use Purlin Lower backing material techniques to prevent buckling is a popular trend to stable can be thought of as a preferred way to maintain. I think that with universality beyond the local-division, national-division and the two countries since the 15th century of Korea and China ancient wooden structures detailed mechanism for the purlin buckling. In middle-late Chosen dynasty, The effect of Deotgeolyi- techniques and fleeting beams reduce the purlin buckling that reduces the load transmitted from purlin and crossbeam of how to reduce the load on the roof portion of the architecture fleeting beams used, which of craftsmanship of the Chosen Dynasty building can be referred to as another technique for preventing buckling purlin. This Korea and China ancient architecture purlin beam structure and material So-seul Timber study. Seems to be able to provide a basic research study to restore and designed the old wooden architectures.

A new species, Asarum yeonbyeonense M. Kim & S. So, is named and described from Mt. Baekdu in Korea. This new species is distinctly different from the related species A. mandshuricum (Maxim.) M. Kim & S. So according to the purple band at the base of the calyx lobes and the thick calyx lobes. In addition, Asarum sieboldii var. viridiluteolum Y. Lee is closely related to A. yeonbyeonense M. Kim & S. So due to its reflexed calyx lobes; however, this variety has green calyx lobes and pubescent petioles. Therefore its scientific name was changed to Asarum yeonbyeonense var. viridiluteolum (Y. Lee) M. Kim & S. So, and its Korean name should be changed into Nokyeonbyeon-Jokdoripul.

In seven species of Korean Asarum, 44 qualitative and 28 quantitative characters were reviewed taxonomically. Among 44 qualitative characters observed in vegetative and reproductive organs, the states of 27 characters were common in all the seven species. Among 28 quantitative characters, five characters have the same values in all the seven species; the number of cataphyll (2-4), leaf (2), calyx lobe (5), stamen (12) and pistil (6). White spots on adaxial surface of leaf (effectively) distinguished A. maculatum and A. versicolor from the other species. Many long soft hairs on abaxial surface of leaf distinguished A. mandshuricum from other species with short hairs. The glandular hairs on inner surface of calyx tube were divided into 2 types, reflecting the taxonomic relationships between the species: Type 1 has non-stalked glandular hairs (A. maculatum, A. sieboldii and A. sp.), and Type 2 has stalked glandular hairs (A. patens, A. versicolor, A. mandshuricum and A. misandrum). The length, shape, colour of calyx lobe and the extent to which the calyx lobe recurves, as well as the diameter and colour of calyx tube throat, were confirmed to be taxonomically valuable. In the case of glandular hair density on the surface of calyx lobe, A. patens with low density and A. sp. with high density were clearly distinct from all the other species with intermediate hair density. Meanwhile, the stylar protuberance length of A. patens (2.9-3.3 mm) was strikingly different from other species (1.4-2.5 mm). Additionally, further examination of the identities of A. yeonbyeonense and A. yeonbyeonense var. viridiluteolum is required.

Taxonomic treatment and the identification key for 6 species and 4 varieties from the genus Asarum (Aristolochiaceae) in Korea were presented on the basis of the morphological analyses. Recently the taxonomy of the genus Asarum in Korea is controversial in the definition of species and the establishment of variation range. Our morphological studies supported that the species A. patens, A. misandrum and A. versicolor should be recognized as independent species by the unique morphological characters such as calyx lobes, stylar protuberance and leaf variegation. Second, A. sieboldii var. cornutum, A. koreanum, A. maculatum and A. sonunsanense, regarded as species or variety by different scholars, showed a close relationship with A. sieboldii by the similar calyx characters. Thus, new combinations, such as A. sieboldii for. cornutum, A. sieboldii for. koreanum, A. sieboldii for. maculatum and A. sieboldii for. sonunsanense, are proposed. And A. heterotropoides var. seoulense and A. heterotropoides var. mandshuricum also had a close relationship, thus, new combinations, A. mandshuricum for. seoulense, A. mandshuricum for. mandshuricum, are proposed. Furthermore, it is appropriate that A. heterotropoides var. heterotropoides, only distributed in Japan, is revised into A. heterotropoides as independent species by the unique character from the 2 varieties above. Consequently, the genus Asarum in Korea is classified into 3 species and 7 forma.

Perforated ray cells are identified for the first time in the Korean species of Deutzia glabrata, Deutzia sieboldiana, Hydrangea paniculata, and Philadelphus schrenckii that belong to Hydrangeaceae but not observed in Deutzia gracilis. These ray cells have simple to scalarifrom perforations in Deutzia glabrata which have vessel elements with scalariform perforations, and have scalariform to reticulate perforations in Deutzia sieboldiana, Hydrangea paniculata, and Philadelphus schrenckii which have vessel elements with scalariform perforations. Thus, the perforations of ray cells in Korean Hydrangeaceae appeared not to be exactly the same as the types of scalariform perforation plates in the vessel elements of same wood.

A dapo type bracket system which consists of chuganpo(柱間包) and chusangpo(柱上包) with a fake-beam adopted a nemok-dori member to cope with oemok-dori member in order to obtain balance between the outer-side and the inner-side of the bracket system. The middle part of the longest rater in the dapo system is supported by three points made by oemok-dori, jusim-dori and nemok-dori members and the area between the rafer supporting points forms a supporting area. The increase of rafter supporting points and supporting area leads to heightening the structural stability and the efficiency of load delivery. In the eave of dapo system the portion where the three supporting points formed by oemok-dori, jusim-dori and nemok-dori members shows as 33% in the early period, 71% in the middle period and 78% in the later period. On the contrary the portion where more than one of the three dori members were omitted shows as 67% in the early period, 29% in the middle period and 22% in the later period. This is the result of the increase of the number and the distance of steps in the dapo bracket system as time goes on. This is because the structural role of three supporting points becomes important as the increase of distance between the dori members leads to the increase of load which burdens on each dori member.

These days sex has become a tool of interest, a constant stream of sex crimes occurs and it brings the age of population cliffs to an age of low birth rates. As an alternative to overcome these problems, we should establish the praying for a child, which has been our ancestors' way of life, as a sacred culture that holds the mystery of life-birth with a new awareness. Therefore, the purpose of this study is not to re-enact the Zhaungam area as a fun and interesting place, but as a sacred place to pray for the nobility, longevity and wealth of life. Based on the spirit of natural love, meeting, healing, and love based on the spirit of traditional culture, Doridori was chosen as the main theme of the project based on the spirit of natural love and life-respect, and the name "Doridori Secret Garden" was given out of 10 medals in Dandong for tourism storytelling. Cultural content becomes a marketing tool for the region and acts as a force for tourists to visit the area. In this context, it was confirmed that the creation of "Doridori Secret Garden" could lead to a high value-added industry that attracts tourists by enhancing the brand value of Andong and showing sufficient significance to become a new attraction. This study is intended to re-create the Zhaungam area as a sacred place to pray for the nobility of life and longevity and wealth of life, noting that people still pray for the birth of their children in Zhaungam and Zhagungam.

Members of the genus Asarum of Korea were reviewed taxonomically, and classified into seven species. Among them, four species - A. koreanum, A. maculatum, A. patens and A. versicolor - were recorded as Korean endemics. The most valuable taxonomic characters in identifying the Asarum taxa were shape, size and color of the calyx tube and lobe. In addition, the presence of white spots on the adaxial surface, size and color of leaf, presence of trichome, shape and size of the stylar protuberance and thickness of the calyx lobe were also important characters. Keys to the species including descriptions and figures of floral structures of each taxon were provided here for the accurate identification of each species.

Deutzia paniculata is an endemic species to the Korean Peninsula. Despite of importance for conservation, the population structure and habitat characteristics of D. paniculata have not been determined yet. We analyzed the ecological characteristics of the species based on the literature review and field survey. Field survey was conducted on May to October 2014 during which 11 quadrats of size $15{\times}15m$ were studied in six regions. Each of the quadrats were further divided into $5{\times}5m$ small quadrats and population characteristics were recorded. The population and habitat characteristics were analyzed, including species abundance (density and coverage), demographic attributes (flowering rates and fruiting plants), vegetation (structure, species composition), light availability (transmitted light and canopy openness) and soil characteristics (temperature and humidity). We found that D. paniculata mainly distributed in Gyeongsangdo (including Taebaek in Gangwondo) along a broad elevational range of 290~959 m (mean: 493 m) above sea level. In preferred habitat the species grows within the slope range of $7^{\circ}$ and $35^{\circ}$ with the average of $16^{\circ}$. D. paniculata was generally distributed on talus deposits and low adjacent slopes. The average number of individual plants per small quadrat was 12.5 with the mean density $0.5stems\;m^{-2}$. The vegetative reproduction was frequent in D. paniculata and mean flowering rate was as low as 15%. Altogether 138 taxa were found in whole observation area with the dominant tree species mainly spring ephemerals, such as Cornus controversa (importance value: 25.5%) and Fraxinus rhynchophylla (importance value: 15.8%). Although, C. controversa usually grows on steep slopes and F. rhynchophylla mostly distributed at high-altitudes, however, both species distributed in disturbed environments and among talus deposits. Thus based on our results, we concluded that D. paniculata is a disturbance-prone species, primarily existing in habitats subjected to natural disturbances, such as floods. The species occurs less at anthropogenically disturbed sites, thus there is no apparent threat to the populations and habitat of D. paniculata.
