In the present study, a new Real Time Subjective Evaluation (RTSSE) system was developed. The system is composed of two parts: a sensibility input part and sensibility evaluation part. The sensibility input part receives values, which are recorded on an input board using a stylus and digital tablet, from each subject's evaluation of his/her own subjective sensibility towards a particular stimulus. The sensibility evaluation part displays the level of pleasantness and arousal on one or two dimensions in real time. An experiment was conducted in order to investigate the feasibility and effectiveness of the RTSSE system. The present study compared Galvanic Skin Response (GSR) with the RTSSE by presenting 28 subjects in their 20s with pictures arousing either positive or negative sensibility. Following the experiment, an off-line subjective assessment using a questionnaire was given to the same subjects. According to the correlation coefficients, changes in subjective sensibility caused by the positive visual stimulus were related more closely to GSR, from the positive visual stimulus, and changes in subjective sensibility caused by the negative visual stimulus were related more closely to GSR from the negative visual stimulus. The questionnaire results showed marked similarity to the average responses of the RTSSE. In conclusion, the most remarkable characteristic of the present system is that it not only assesses the average sensibility when stimuli are presented, but also shows the changing strength of sensibility over time.

This paper aimed to show the whole conservation process of the human shaped terra cotta mask that was excavated from one of construction sites at Jungcheon-ri, Geumsan-myeon, Jinju. This mask was X-rayed to get the correct making techniques and there are 4 holes on the top of the head and each diameter of the 3 holes is exact and the other hole is different from the three. The long and sharp shape of the nose is in trapezoid which was separately made with clay and put on (the face). It's found that there are round grooves each around upper and down lips. (upper in length: 10mm, down in length: 6 mm). All restoring materials and adhesives used for restoration to associate each piece are reversibility materials. According to a few points on buried bones of animals distributed around the sites, holes and grooves on the top of the head, ears and teeth to wear something, it academically presumes that this mask could be possibly used for the group ritual. Especially, the whole procedure from excavation to scientific conservation process resulted to have a special exhibition to give the public new eyes how the exhibition realizes to the public.

The Back garden in Wanggung-ri Site, Iksan clearly presents an aspect of the landscape gardening techniques of the Baekje, which are significantly unique in the landscape gardening history of East Asia as the structure connected to the main garden through a complex waterway system on a hill. The rear garden has a complex waterway system comprising a large inverted U-shape waterway and its branch waterways, sinuous waterway and water catchment system to enhance the landscape effect with a minimum amount of water on a hill, reducing damage by floods in the case of heavy rain and securing the amount of water required by the main space in the palace. A landscape element using various kinds and sizes of oddly shaped rocks decorated the water catchment area inside or around the large inverted U-shape waterway. On the top of the hill, the center in the Back garden, a building site in the size of 4 Kans each on the front and side was made on a square base surrounded by a round base stone. The building was identified on a space partially surrounded by the rectangular stonework on the left and right slope of the hill. While the functions and roles of the rectangular stonework are not accurately identified due to the poor conditions of the present site, the stonework may be related to the building inside it. The back garden in Wanggung-ri Site, Iksan has a winding pond-shaped waterway to pull or push water into or out of the garden in a rectangular pond shape, which was a conventional landscape gardening technique during the Baekje period. Since the main garden and the back garden in Wanggung-ri Site, Iksan form a systematic connection system, this paper tried to newly establish the main garden inside Iksan Wanggungseong as the 'royal garden'.

Three bronze bells excavated from the Hoeamsa temple site were investigated for their microstructures and chemical compositions in an effort to understand the technology applied in fabrication, which may represent the related industry established in the early Joseon period. The result shows that the bells were cast from alloys of approximately 85% copper-8% tin-7% lead. The chemical analysis for ten trace elements shows that they were all kept below 0.3 weight %, suggesting that the alloys were made of relatively well-refined copper, tin and lead. The presence of sulfur and iron indicates that chalcopyrite or chalcocite may have been used in the smelting of copper. Evidence has been found that the bells were cast by pouring the liquid metal from the top of the sand molds that were set up in an upright position. No additional treatments, thermal or mechanical, other than a little grinding were applied upon the completion of casting. After the shaping process, a balancing plate was attached to the top of the bell using a steel connection ring. The connection assembly was then fixed to the main body by using molten bronze as a solder. The surface inscription was found carved using different techniques. The differences in the order of strokes and the calligraphic style indicate that the carving was carried out by more than one master. In the absence of documentary evidence on past bronze technology, the present bronze bells with known chronology, provenance and the main agent of production, prove to be a rare and valuable archaeological material for the understanding of the related technology in use in the early Joseon period.

It is called the "Painted lead glaze pottery" that is painted green, brown, yellow over white or light yellow glazed base among glazed pottery in the Northern Qi Dynasty. Even though the white glazed pot painted green with three ears and the yellow glazed jar painted green with long neck is found in the Fan-cui Tomb in Honghetun Village, Anyang City, Henan Province in 1971, these potteries were not focused in academic circles. While the white glazed pottery found with them was thought as the earliest evidence of the white porcelain that the date is clear, it has constantly been discussed so far. In this paper, focused on the painted lead glaze pottery, the materials from tombs and kiln sites are organized, and based on them, the decoration feature and production technique is analyzed. The emergence time of this pottery is checked by the date of tombs and the social value of this pottery is considered by the position of the buried person. The painted lead glaze pottery of the Northern Qi Dynasty has independent character such as porcelain clay, twice firing burning and painting technique over glazed base. This character emerged from several glazed potteries in the Northern Wei Dynasty and it continued to the Northern Qi Dynasty. At last, the white painted lead glazed pottery appeared. The painted lead glaze pottery was formed by the combination of a shape of the ceramic in Southern China and painting technique after the Northern Wei Dynasty in Northern China.

Linoleum is a resilient, hygienic, and eco-friendly floor covering. It was developed in England by Frederick Walton in 1863. Made of cork flour, linseed oil, and burlap as its main materials, the flexible and waterproof linoleum became globally popular in the early 20th century. Unlike the vinyl coverings, the burlap-backed linoleum was used not only in commercial spaces but also in household areas like kitchens, bathrooms, and even living rooms. As a global product, linoleum was imported and used in Korean palaces like Deoksugung and Changdeokgung in the early modern period. According to the record Deoksugung Won-Ahn, linoleum was applied to the major buildings, including Hamnyeongjeon, Deokhongjeon, and Jeonggwanheon, and various other venues. The linoleum used in these places are mainly monochrome blue and brown color, which probably means that they are from England. The trade records in the early 20th century show that linoleum was imported mainly from England and America. The Ewangjik building floor plan in the Changdeokgung Palace shows that linoleum was used extensively. There are even some originals, which were laid in 1920 and left in the Changdeokgung Palace. When Daejojeon and Huijeongdang were rebuilt in 1920, the interior was outfitted with western features and linoleum was used in areas such as bathrooms, the tonsorial parlor, and one of the rooms on the west side of Huijeongdang. In situ in the Daejojeon and Huijeongdang areas in the Changdeokgung Palace are monochrome, patterned black, and stylized floral tile patterned, which are closely similar to American products made by ALC and Armstrong company. This study will help us better understand linoleum's characteristics, its uses and the material itself. It will also form the basis for the restoration of Changdeokgung Palace as well as other modern interiors with linoleum flooring in the future.

Tattoo, which has been 5000 years' history is the symbol of the collective society. It was used as one of the methods not only to defense and camouflage but also to decorate themselves. In modern society, tattoo culture is either limited to ethnic minorities or be used as a decorative element of personal preference. Among them, the Chinese ethnic minority, the Dai, is still maintaining its tattoo culture, but gradually faded. Hence, the necessity of protecting the tattoo culture of the Dai is essential. The procedures and methods of this study were conducted by analyzing an antique book, explore residential areas, data research, and data collection through interviews. According to research, the tattoo culture of the Dai has been consistently passed down through traditional tattoo pictorial books, the memories of tattooists, and the stories of people who got tattoos. However, the Dai's traditional culture and customs are influenced by the China political reform between 1952 and 1956, confirming that the size of tattoo culture was reduced than before and evanesces. As a result, in order to inherit the ethnic minorities Dai's tattoo heritage, records of tattoo culture are required. Besides, it is considered that the records of tattoo culture and interpretations of tattoo culture by tattooists and the people who got a tattoo due to aging in the future should be studied.

The gilt-bronze-and-silver shoes, excavated from the Tomb of King Muryeong, revealed many defective parts, which constantly raised in-depth re-investigation and reporting. In that point, scientific treatment and analysis were conducted to investigate the manufacturing techniques applied. The conservation treatment was carried out with an emphasis on the restoration of the original form and joining parts. As a result, the upper part of the right shoe and some part of the back heel were joined, confirming the joining method and the number of rivet used for instep bonding. From the component analysis, it is presumed that the outer plate was gilded with mercury amalgam on pure copper, and pure silver was used for the inner plate. The main pattern of the gilt-bronze-and-silver shoes includes designs of phoenix, lotus, and six-petal flower, while the lotus pattern is high in terms of ratio. Thus, youngnaksa(twisted gilt-bronze thread), geumdongsa(gilt-bronze thread), wondujeong (rivet), and samyeonjeong(quadrangular cleats) were used for bonding each plate. Twisted gilt-bronze thread was used to join the inner and outer plates, while the center and rear of the inner plate were combined with only gilt-bronze threads. From the fact, it is presumed that the joining method was different whether the function was decoration or just bonding. Regarding the manufacturing process, traces of burnishing were confirmed on the outer surface of the gilt-bronze and silver shoes, but no burnishing traces were identified on the inner surface of the silver plate, which is likely to prove more importance put on the finishing of the outer plates rather than that of the inner.

We deduced the proper estimation methodology for the amount of carbon sequestration by damaged trees for Environmental Impact Assessment (EIA). The nine development projects related to renewable energy, damaged trees occur, assessment status and used method of evaluating the carbon storage of damaged trees were summarized. And after re-calculating the carbon storage of damaged trees through allometric equations, the difference between the two groups, re-calculated the damaged trees carbon storage and the damaged trees carbon storage in the report, was validated. As a result, damaged trees carbon storage in words was more than the re-calculated damaged trees carbon storage, and it was statistically significant (p<0.005). This result means that the existing method for calculating damaged tree carbon storage is overcalculated. It was judged that it was necessary to improve the calculation method. Therefore, allometric equations suitable for each dominated-tree species should be used when calculating the damaged tree carbon storage. Furthermore, we propose to establish a carbon storage calculation system based on actual data from the ecosystem so that researchers can efficiently and accurately the damaged trees carbon storage.
