Gyeongju, the capital of Silla, is the very essence of the culture and technology of the thousand-year-reign of Silla. However, few studies have been conducted on the landscape sites of the capital of Silla other than Donggung Palace and Wolji Pond, due to the lack of related data. Therefore, this study examined the construction characteristics and nature of the garden pond in Guhwang-dong, whose complete appearance was identified through excavation following Donggung Palace and Wolji Pond. Since the excavation of the garden pond in Guhwang-dong, Gyeongju, there have been disagreements in academia as to whether it is a palace pond or a temple pond of Bunhwangsa Temple. Considering the unique characteristic of the garden pond that it is divided into two periods, it was interpreted that it would have functioned as a ritual facility related to Ryong (oriental dragon) belief in the 6th to 7th centuries, the first period, and as a garden pond with enhanced landscaping functions in the 8th to 9th centuries, the second period. In addition, it is highly probable that it was the site of Cheongyeongung Palace (青淵宮) and Jochujeong Pavilion (造秋亭) mentioned in the literature records. The "ㄹ"- shaped waterway, a characteristic facility of the first period, was found; however, considering its width and depth, it is insufficient to conclude that it was a simple drainage facility. Rather, it is more likely that it functioned as a passageway for the conceptual entry of Ryong during Ryong rituals. Furthermore, some have suggested that it may have been a ceremony-related Yusang-goksu (流觴曲水) facility. These facilities related to Ryong rituals were reorganized in the second period. Specifically, the nature of the garden pond was changed centered on the landscaping function in connection with the addition of a curved revetment, garden stone, and pavilion buildings, and the dismantlement of the "ㄹ"-shaped waterway and hexagonal building. As for nature, it can be regarded as a royal facility in terms of decorative elements including the ritual function of the first period and the gwimyeonwa (ghost face tiles) of the second period. Judging from the fact that the upper part of the embankment adjacent to the west side of the site was removed, it is very apparent that the main building was located on the upper part of the embankment. There would not have been a large-scale building site because it served the functions of ritual and recreation, rather than being the residence of the king.

The purpose of this study is to offer raw data regarding landscape plantings of traditional cultural heritages by surveying and analysing the actual flora and landscape planting species distributed in Donggung Palace and Wolji Pond in Gyeongju, Korea. The results are as follows. The flora were summarized as 149 taxa including 65 families, 117 genera, 134 species, 1 subspecies, 10 varieties and 4 forms. The naturalized plants were of 18 taxa including Rumex crispus, Trifolium repens, Ailanthus altissima, Veronica persica, Senecio vulgaris, Festuca myuros and the like. Invasive species included Rumex acetosella. As a result of the analysis of chronological changes in landscape planting species, 23 taxa were planted in 1979, whereas 48 taxa were planted in 2014. Therefore, the number of these species increased by 25 taxa. The landscape planting species were of 48 taxa including 6 taxa of evergreen trees, 2 taxa of evergreen shrubs, 27 taxa of deciduous trees, 12 taxa of deciduous shrubs and 1 taxa of other. In present conditions by sections, Section A was 25 taxa, 15 taxa of Section B, 13 taxa of Section C and 29 taxa of Section D. The species planted in common were 4 taxa including Pinus densiflora, Acer palmatum, Euonymus alatus and Rhododendron yedoense for. poukhanense. The problems in the present conditions of landscape planting were volunteer species, the occurrence of scrub and vines and the spread of invasive alien plants. To restore and improve the planting landscape and facilitate tree growth, scrub, volunteer species and invasive alien plants must be removed.

The stable isotopic composition of bone collagen plays an important role in reconstructing palaeodiet, nutrition, palaeoenvironment and their lifestyle. This is the first case in extracting palaeodietary information and breastfeeding pattern of Goryeo people using stable isotope analysis due to the lack of human remains in this period. We analyzed human bone collagen excavated from Gyeongju Donggung palace and Wolji pond No.3. The average values of δ¹³C and δ¹⁵N are as follows: (δ¹³C(‰) = -19.5 ± 0.9‰, δ¹⁵N(‰) = 11.1 ± 1.1 ‰, (n = 4). Stable carbon isotope values shows a mainly C₃ based diet such as rice and barley. Stable nitrogen isotope results implies the protein sources attributed to terrestrial animals. There are various age groups in this study, which are adult, child and infant. Two individuals within early childhood age ranges (< 3 years) shows more elevated δ¹⁵N values than that of adult and this result implies the continuation of breastfeeding in this group until the age of 3. The results provide new insight into the breastfeeding pattern of Goryeo people, where breastfeeding and weaning practices have important implication for fertility, population dynamics, migration pattern and disease.

After the great King Munmu constructed Donggung-palace and Wolji-pond in 674, original landscape could not be estimated due to lack of related materials for some 1,250 years until it was surveyed in 1922. Accordingly, the study, to estimate changes of Wolji-pond landscape more accurately, analyzed the study of Hara(1932) and pictures in the Japanese ruling period etc. - these had not been studied so far. The study results are as follows. As a result of comparing survey maps of 1922 and one of 1975, it was found that during 53 years, whole area excluding island showed eroded part by 2~4m, severely, there was mounding area which was lowered by 10m. And it was identified through survey map of 1922 and pictures of the 1950's that inside southern shore protection of the No. 1 construction site were many landscape-stones(景石) which can make imagine a hill; here was water path. Trace of such path etc. remained just before excavation. 2) The construction site No. 3 and 5 in peak shape were higher than construction site No. 1, 2, and 4. Accordingly, there is high possibility that construction stood on high stylobate. So it is wrong that construction site No. 3 and 5 are restored in same height as other construction sites. Comprehensive restoration basic plan made in 2012 was also wrong. As a result of estimating changes of landscape through pictures before excavation of Wolji-pond, the author could identify changes of landscape in mound area and pumice stones which showed much changes in drawing. The study has limit due to lack of space. But if more pictures can be analyzed, it could further help for estimating original landscape of Wolji-pond.

With regard to Gung-jung Yeon-hyang(宮中宴享; court banquet), the frequency of banquets that were held at one time beginning Mu-ja J in-jak(戊子進爵; a royal banquet held in 1828) in 1828 (the 28th year of King Sunjo (純祖)'s reign). In proportion to this frequency, there was an increase in the need and importance of Suk-seol-so(熟設所; a kitchen built in temporarily house for court banquet) and Jung-bae-seol-cheong(中排設廳; a temporary place to put offerings) as a space to assist court banquets. Although Suk-seol-so was a temporary but large-scale facility, it was frequently used for long periods. This facility was flexibly established using the variability of Dong-gung(東宮; Palace for Crown Prince) and enhanced the efficiency of censorship and security in conjunction with palace gates and Suk-wi-cheo(宿衛處; guard station, guard room). In addition, it was reused according to the period when the nation and royal family gave finances or banquets. Jung-bae-seol-cheong was established in the place connected to the central space of court banquets and worked as buffer space to resolve the tension on the day of the event. The location where Jung-bae-seol-cheong was established enabled us to confirm the applicability of Bok-do(複道; corridor) connected to Chimjeon(寢殿; royal residence) when holding court banquets. In short, Suk-seol-so and Jung-bae-seol-cheong were auxiliary spaces, but were considered importantly in the palace operation when holding court banquets.

This study suggests several concepts on the brand role, brand loyalty, and stickiness on the web, and investigates the relationship between the stickiness/loyalty of the web brands and general characteristics of the web(interactivity, contents and community). This study also examines whether the web stickiness acts as mediating variable. As the result, the interactivity, contents, and community has positive effects on the web stickiness. This results shows that these are very important factors for valuable navigation activities and continuous and more frequent visits giving closer communication and rich contents to users. And the stickiness plays a role as mediating variable between this relationship, this is that interactivity, contents and community can be shift to the loyalty of the web-brand through this stickiness. This study suggests several effects on theoretical and practical area, and offers important theoretical backgrounds for the study of web stickiness.

This study was carried out to investigate the backgrounds and spatial characteristics of the sericulture in the rear garden of the palace in Joseon Dynasty. Joseon Dynasty made the various efforts not only to enhance the promotion of agriculture but also sericulture since the main industry of Joseon Dynasty was farming. At the very beginning, Joseon Dynasty planted mulberry trees and built a silkworm-raising room(蠶室) around the Donggung(東宮). Then, King Sungjong(成宗) made Chaesangdan(採桑壇) in Changgyeong Palace and performed Chinzamryae(親蠶禮). The location of Chaesangdan varied as time goes on until the king Gwanghaegun(光海君). Lastly, King Yeongjo(英祖) made Chaesangdan and Junghaechinzambi(丁亥親蠶碑) in Gyeongbok Palace. Yeongjo(英祖) showed a strong attachment to Gyeongbok Palace and actively encouraged the sericulture. Chaesangdan was built in the east side of the palace which was appropriate for planting mulberry trees. Furthermore, a silkworm-raising room was located in this place at the era of King Sejong(世宗).

We investigated the records of astronomical phenomena in the Hyeonjong-Donggung-Ilgi written by the educational office for a crown prince, Sigang-won, during the time of a crown prince of the king Hyeonjong (i.e., from 1649 to 1659). Of the total of 3,625 days, 3,044 astronomical accounts were compiled from astronomical records of 2,003 days. We classified these astronomical accounts into 16 items, grouped into five categories, and statistically analyzed each group. In our analysis, the accounts for atmos-pheric optical phenomena equates to 57.9% of the total, and for celestial phenomena visible during the daytime the percentage is 17.3%. The records related to the approach between two objects such as planets, moon, and stars account for 3.3%, and solar or lunar eclipses take up 0.6%. The ratio of accounts regarding meteor, comet, and fire light (火光) stand at 13.8%, 0.30%, and 6.8%, respectively. Sunny days account for 71.1% of all days per year during this period. We determined that the distribution of the fire light by month is similar to that of the solar halo. We also found that the astronomical records from the Annals of the Joseon Dynasty correspond to only 30% of those of the Hyeonjong-Donggung-Ilgi for the same period. In particular, the phenomena of celestial objects occurring outside the atmosphere are transmitted to the Annals of the Joseon Dynasty in a higher proportion than the phenomena inside the air. It is therefore necessary to use a historical diary like a Donggung-Ilgi to interpret the phenomena in the air such as atmospheric optical events, meteor, and fire light.
