Group features such as group cohesion and consistency on appropriation(COA), which have been constructed through social interactions, should be noted for characterizing online game, especially, clan based massively multi-players online game (MMOG). This study attempted to identify the relationship between group characteristics and users' effectiveness of MMOG considering group experience. For this purpose, a research model was suggested: group cohesion and COA are variables for explaining group features, perceived use control is a variable for individual competency of playing MMOG, and perceived winning and perceived enjoyment are dependent variables. Moreover, group experience was included as a moderating variables for two relationships, group cohesion-preceived winning and COA-perceived winning. For the validation of this research model, 100 users for Sudden Attack which is one of very well known MMOG games were surveyed by questionnaires. Before survey, they were grouped into 10 teams and were played over ten times by team for perceiving group consciousness. In result, most hypotheses were statistically supported except the relationship between group cohesion and perceived winning.

The purpose of this study is to estimate the location and space configuration of Sauidang(四宜堂), which is a house in the late Joseon period. Sauidang was built by Hong Man-hoe(洪萬恢), the last son of Princess Jeongmyeong(貞明公主), was used as a house for Pungsan Hong clan(豊山 洪氏) for approximately 150 years, and is now defunct. However, the existence was estimated through Sauidang-ji("四宜堂志") compiled by Gwan-am Hong Gyeong-mo(冠巖 洪敬謨) in 1824. Based on the mention that "Sauidang was located in Hundo-bang(薰陶坊) of Ihyeon-dong(梨峴洞)" and the literature referring to "the site of Myeongryegung Palace(明禮宮)", this study estimated the location of Sauidang. Maps and photographic data in the modern age enabled us to examine the utilization cases of medium- and large-sized lots by examining the correlation with the current Embassy of the People's Republic of China in the Republic of Korea. In addition, it was possible to estimate the spatial configuration of Sauidang with a focus on words to clarify the detailed explanation of Sauidang mentioned in the literature and spatial relationship.

This paper is a study on the Bisotun relief of the Achaemenid Dynasty in ancient Persia. The Bisotun relief consists of the relief and the inscriptions which was completed through 7 phases. The inscriptions describe how King Darius suppressed the rebels in Elamite, Babili and ancient Persian languages. This relief is a work during the early Darius period and it describes using the traditions of Mesopotamia in terms of the theme and structure. In terms of structural features, it follows the typical features of the Assyrian arts, the beard and the shape of hair style. On the other hand, the smooth curves used to describe the creases of the clothes and the supple body was not a typical oriental feature. It was known to be because of Greek influence from their communications. It also showed the dressings of the clans that made up the Achaemenid Dynasty through the 9 rebellions wearing clothes unique to their clan and the inscription that was inscribed with the name of the clans. The clothing and ornaments they were wearing can be divided into two groups, the clans that wore one-piece style Persian dress and clans that wore tunic jackets and trousers which is a typical dressing style of the nomads.

Astronomical data making such as forming a calendar, period of day, determining the time of rising/setting of the sun and the onset of twilight are essential in our daily lives. Knowing the calendar day of the past is particularly crucial for studying the history of a clan or a nation. To verify previous studies in the calendar day of the Joseon dynasty (1392 - 1910), we investigate the sexagenary cycle of the new moon day (i.e., the first day in a lunar month) by using sources such as results of the calculations using the Datong calendar (a Chinese Calendar of the Ming Dynasty) and the data of Baekjungryeok (a Perpetual Calendar; literally, a one hundred-year almanac). Compared with the study of Ahn et al., we find that as many as 17 sexagenary cycles show discrepancies. In the cases of nine discrepancies, we find that the sexagenary cycles of this study are identical to those of the almanacs at that time. In addition, we study five sexagenary cycles by using the historical accounts of Joseon Wangjo Sillok (Annals of the Joseon Dynasty), Seungjeongwon Ilgi (Daily Reports of Royal Secretariat), Chungung Ilgi (Logs of Crown Prince), and so forth. For the remaining discrepancies, we present historical literature supporting the results of this study. This study will greatly contribute to the identification of the lunisolar calendar days during the Joseon dynasty as the dates of the modern (i.e., Gregorian) calendar.

The purpose of this study is to analyze the evolutionary process of Ddeulzip. The subject of this study is a clan family of Andong Kwon in Andong Area. Ddeulzip's evolutionary process of the construction and management is divided into largely three periods in Josun Dynasty. The establishment and changing process of Ddeulzip for Andong Kwon's family are analyzed according to three periods called the early(15~16C), mid(17~18C) and late(19~20C). The characteristics of the early and mid period are that they created their own ancestral building form of Ddeulzip. Those of the late period are in their strong will to make similar scale of Ddeulzip. And during the late period, although the construction of new Ddeulzip was started in the early stage, no more formation of Ddeulzip was made as it approached toward the late stage. And most important point is similar constructional space(gan) of first time. The residential Ddeulzip of Andong Kwon's family created at the 19C can be regarded as an representative example of large space that shows a typical form of housing by noble residents at the time.

Three wood coffins of Chosun Dynasty period buried about 450 years ago were excavated in the sound condition in Andong area in the early 1998. The proprietors of wood coffins were grandparents, Mr. Myoung Jong Lee and Mrs. Mun, and their grandson, Mr. Eung Tae Lee, and the social standing of their family was known to belong to the nobility in those days by the clan genealogy. All the wood coffins investigated through light microscopy had same anatomical characteristics as follows: abrupt to somewhat abrupt tracheid transition from earlywood to latewood; normal longitudinal and horizontal resin canals with thin-walled epithelium; tylosoids in resin canals; bordered pits frequently in 1 row on radial walls of tracheids; 1 or 2 window-like pits per cross-field; uniseriate and fusiform rays; heterogeneous rays composed of body ray parenchyma cells and marginal ray tracheids or homgeneous rays composed of only ray tracheids; dentate ray tracheids; occasional trabeculae traversing tracheids in radial direction. Based on theses microscopic characteristics, all the wood coffins were identified to be Korean red pine (Pinus densiflora) or Korean black pine (Pinus thunbergii). Korean black pine growing naturally in coastal area might not be probable because the site of excavation, Andong area, was mountainous and inland area of Korea Thus, Korean red pine was thought to be the possible species for the wood coffins because of its natural distribution through the Korean Peninsula and the easy availability.

Geum'yeok-dang house in Andong was originally constructed in 1558. The original floor plan of the upper base featured a 90-degree tilted '日' shape, and had inner court(內庭) on each side of 'Jungdang(中堂, center hall)' building that was placed on the south-north axis. When designing the building, the Neo-Confucian client of Geum'yeok-dang applied his understanding of how Ga'rye("家禮") defined the structure of ritual space. Consequently, 'Daecheong(大廳)', the place where guests were greeted and ancestral rites and coming of age ceremonies for male were held, was built in a protruding fashion. 'Jungdang'[otherwise known as 'Jeongchim(正寢)'], where coming of age ceremonies for females were held, the master of the house faced death, and memorials for close ancestors were held, was placed at the center of the residence on the south-north axis. The Geum'yeok-dang today was greatly renovated in the early and mid 18th century, due to the spread of 'Ondol' heating system. As the Ondol heating system became popular, the pre-existing drawbacks and the inconvenience of the house stood out clearly. As a result, the house was renovated into today's structure consisting of '口' shape 'Anchae' and 'Daecheongchae' in separate building.

This study is about the three pieces of jackets with a symmetric collar that was used to fill in the empty spaces in coffin excavated in 2004, from Seok-nam-dong, Nam-gu, Incheon. The similarities of these three jackets are that the collars are symmetric, there are seops(the outer bodies to overlap the front sides of a jacket) with pleats, and openings on the side seam. The No.2, and No.6 seem to be jegori to wear over others, and the fabrics used for No.2 is damask with cloud pattern, and damask with lotus flower pattern. For the No.4, satin was used and there is peacock pattern weaved on satin using golden thread. No.41 is unlined clothes made with Suk-cho, and the distinctive feature about this clothes is that the collar, and the neckline are very narrow. The three jackets are similar with the recently reported clothes of Kim clan of Gang-leung (deducted to be buried in 1520), the collection of Seok Joo-sun Memorial Museum. Through this report, it provides information about some aspects of upper class women's clothes.

We present historical materials supporting the results of this study for the remainder. In conclusion, we think that this study will greatly contribute to the comparison between luni-solar calendar days during the Joseon dynasty and those in the modern (i.e., Gregorian) calendar.

This study investigates spalling properties of high performance concrete, 60MPa clan, made with the various types of coarse aggregate and adding ratio of polypropylene(PP) fiber. As experimental parameters, totally sixteen specimens of ${\phi}100{\times}200mm$ in size are prepared: one specimen for control without fiber, ten specimens with different coarse aggregate types, along with 0.05, 0.1, 0.15 percent of PP fiber in each. 1 hour fire test is conducted and then spalling appearance, spalling degree and residual compressive strength are examined. In addition, sit specimens made with two types of coarse aggregate site, along with same adding ratio of fiber are supplementally done, and only spalling properties is examined. Test results showed that control concrete and most specimens containing 0.05% of PP fiber exhibited 4 to 3 level of spalling degree, resulting severe explosive spalling, except for the specimen using basalt aggregate(Bc) showing 2 to 3 level of that. Especially, the Bc specimen containing 0.1% of the fiber exhibited that residual compressive strength value was 32%, which is 10% higher than other specimens using limestone or granite. Spalling resistance performance was also effective as aggregate size increase.
