In this study, the design characteristics and the cognition characteristics are investigated and conducted a survey of a bus stop, which most affects to the road scenery among the road fixture. and the result follows. The design characteristic of a bus stop is the uniform, as a box or appears urban image strongly which is not conform the Farm-village. The preference of the I image, A image and H image are high but on the other hand the preference of the E image, D image and F image are lower then average. As following conducted cognition characteristics, affirmative image is similar then the Korean traditional loop shape or using natural materials. It appears that the traditional image or the natural image is preferred then urban images by individuality of the Farm-village. Therefore, in the future, the design of the Farm-village bus stop needs to consider an area features and an environmental preservation design when design.

In this study, I investigated on the ultrastructure of scalp skin from full term baby mummy by using transmission and scanning electron microscopy. The baby mummy was found within the uterus of a 16th century (Joseon Dynasty) mummified woman aged 20${\sim}$30 years old. In scanning electron microscopic study, I found that the outer surface of scalp skin containing of sweat gland and stratum corneum are well preserved. The skin of the scalp measured about 1 mm in thickness and the epidermis was well distinguished from the dermis. In transmission electron microscopy, the shape and structure of the epithelial cells were not confirmed. I also observed well preserved collagen fibers composed of collagen fibrils with cross banding pattern ultrastructurally. But, the other connective cells were not observed due to decomposition of the dermis.

Experiments were performed to study the activity and fertility of grey mullet (Mugil cephalus) sperm after the courses of cold storage and cryopreservation. The head of spermatozoon showing spherical shape was sized $1.26{\pm}0.08 \{mu}textrm{m}$ in diameter and its nucleus contained numerous granular chromatins. Flagellum of tail showed typical 9＋2 structure. Preservation of grey mullet sperm was the most effective when it was stored with serum of the same species at $0^{\circ}C$ and sperm activity index was similar in egg-tris, 0.1 M, 0.3 M and 0.5 M glucose. When grey mullet sperm were cryopreserved in MFRS as diluent with 10% dimethyl sulfoxide was effective compared with other diluents. Some of post-thawed spermatozoa showed the enlarged head and ruptured plasma membrane compared with unfrozen spermatozoa.

So far, many researches have been done to index high-dimensional feature values for fast content-based image retrieval. Still, many existing indexing schemes are suffering from performance degradation due to the curse of dimensionality problem. As an alternative, heuristic algorithms have been proposed to calculate the result with 'high probability' at the cost of accuracy. In this paper, we propose a new extendible hash-based indexing scheme for high-dimensional feature values. Our indexing scheme provides several advantages compared to the traditional high-dimensional index structures in terms of search performance and accuracy preservation. Through extensive experiments, we show that our proposed indexing scheme achieves outstanding performance.

Raymond, who adopted Le Corbusier's Errazuris House Project, built Karuizawa Villa by incorporating Japan's aspiration for Western modern architecture and strong convictions regarding the preservation of traditional culture heritage, which were prevalent in Japan at the time. Despite the controversy over his plagiarism, Karuizawa Villa shows several unique architectural characteristics. First, in terms of the arrangement and access system, the villa has a common space that affords a view of the lake by accessing from the mountain side. Second, in terms of spatial composition, the common space is connected to the mesonnette by placing a trail to enable enjoyment of natural scenery. In particular, personal space is planned in the shape of a cross by connecting several surfaces to the outside in order to secure enjoyment of the natural environment. Lastly, in the aspect of structure and materials, both architectural buildings adopted masonry by using natural stone as well as building materials suitable for each region and climate by using logs in constructing the main columns and beams. Through Karuizawa Villa, Raymond is considered to have established his own style by combining the standard of Western modern architecture and the elements of Japanese traditional architecture while valuing local architectural technology.

A total of 64 specimens of trace fossils were collected from the Jinju Formation of the construction site of Jinju Aviation Industrial Complex, and from the Haman Formation of Namhae Gain-ri fossil site. The fossils are continuously and regularly meandering sine-curve in shape. The fossil varies in morphology: width between 0.2 and 5.6 mm, wavelength between 1.5 and 28 mm, and amplitude between 0.9 and 7.9 mm; the Jinju specimens are commonly wider than the Haman ones. The ratio of wavelength to amplitude is more or less regular regardless of width of the specimen, and the linear correlation of the ratios shows that the Jinju specimens fit better than the Haman specimens. Taking all morphometric parameters, specimens in all size ranges are temporarily identified as ichnospecies Cochlichnus anguineus. In order to obtain more distinct and clearer images of Cochlichnus, we selected two specimens and applied a new imaging technology RTI. For photography of the trace fossils, 50 to 80 images were taken per set with photometric lighting close to the surface and horizontally. RTI technology clearly showed that the images of tiny fossils were improved: the surface contrast become sharper and messy and unnecessary information disappeared. Currently, RTI technology is used in many fields including preservation of cultural properties and archaeology. As a consequence, we hope to apply this technique to the field of paleontology, especially to the study of trace fossils of very small size.

This study is meaningful in figuring out how much the Korean people's awareness of hanok has increased even though interest in hanok has also increased due to the Korean Wave craze. Therefore, with respect to the exterior of hanok, which is visually recognized first, the level of experts and ordinary people is grasped through a semantic discrimination scale, and the degree of visual recognition is to be investigated centering on the color image of hanok buildings. This is the process of thinking about how the Korean image should be reflected in the design, and we want to suggest the direction that modern hanok should go. The study compared and analyzed the difference in visual color based on the elevation of the hanok using a 7-point and 5-point scale method for the general public and experts, and utilized the IRI adjective vocabulary scale and the color matching image scale to construct new hanoks with insufficient differences in appearance and shape. It can be applied to design and image preservation and construction of existing hanok.

This study aims to document the conservation treatment of the fine-hemp official headgear housed by the National Museum of Korea, and to reconsider its existing name following the restoration of the original form of the damaged cultural heritage asset. The headgear consists of a single inner frame with a vertical line at the front, a single outer frame surrounding the inner frame, and a double-layered headband that spans the circumference of the wearer's head and joins the inner and the outer frames. This study applied a conservation treatment to the men's undyed hemp headgear of the Joseon Dynasty in order to remove contaminants and foreign substances on the surface and repair the partially deteriorated and damaged fabric, thereby restoring and stabilizing the original shape and preparing it for exhibitions. The hemp headgear was sewed both by hand and with a sewing machine. Although its overall composition and style are similar to the same type of official headgear from the Joseon Dynasty, the use of a sewing machine supports the assumption that it was produced in the early 1900s. This study identified similarities between the overall composition and shape of the fully-preserved hemp official headgear and those of the jangbogwan, a type of men's official headgear worn by Confucian scholars as part of their everyday attire, and compared it with the shape of jangbogwan seen in documentary records, illustrations, prior research, and portraits from the Joseon Dynasty, as well as with the characteristics of extant jangbowan artifacts, eventually concluding that it is appropriate to classify and name the headgear as a jangbogwan.
