Hydration and physical characteristics of chemically-bonded phosphate ceramic (CBPC) binder based on dead-burned Mg-O with six different blends are investigated for efficient repair construction material by retarding set phase with $H_3BO_3$. The test specimen of the blender with silica fume shows higher compressive strength after 75 days. The CBPC with silica fume results in higher modulus of rupture that others. The test specimens of CBPC eludes lower calcium ion than that of OPC (Ordinay Portland Cement). The X-ray diffraction pattern shows that hydration results in the formation of magnesium hydroxide, M-S-H gel and $MgCO_3$ for the specimen with silica fumes. Combination with calcium for MgO is not desirable due to no formation of chemical bond between two components. Based on the experimental program, the mixture of MgO and silica fume shows efficient performance in strength and durability.

Current perception of games is divided. On the one hand, they are criticized as harmful entertainment due to their violent content and addictive nature, and on the other hand, they are evaluated positively as products of a creative industry that offers alternative, interactive entertainment. Based on the latter, this paper will reevaluate the positive element of such games in relation to the museum, the canon of historical and cultural evaluation. The analysis on game culture introduction to the museums consists of three categories: the practical application that includes educational, communicational, and promotional purposes; the approval of games as industrial assets and their extensive cultural influence; and the indirect acceptance of art works using games. A panoramic view of game culture development would promote research on the link between game culture and museums; furthermore, it would establish a basis for an introduction of game culture in academia and predict the future of the industry.

This study considered the factors of city brand reinforcement and city revitalization through a case study of two cities that were successful in revitalizing using a brand strategy. World leading cities are securing city competitiveness through the culture resources, particularly traditional culture, as a key asset to highlight the cities' uniqueness in increasing their value. The Confucianism influence on Korean traditional culture has a valuable content like etiquette, ritual ceremony, food, education, etc. as well as culture heritage in historical architecture. Therefore, it can be used as the city's assets to promote it worldwide. On the other hand, there is difficulty in preserving most Confucianism culture content and the intangible cultural properties have been neglected. This needs to be applied actively to be used on a city brand strategy. This study reviewed the successful case of Andong city in Korea and Qufu city in Sandong, China and suggests ways of raising the cities' brand power.

The purpose of this study is to clarify the historical flow of baekdong alloy's usage according to the alloying materials mentioned in document records. For this purpose, we first overviewed the use of copper as a base material for white copper alloys and other types of copper alloys. Baekdong is an alloy of copper and other metals and is currently defined as an alloy of copper and nickel. However, depending on the research subjects and time of the scholars, baekdong may be defined as a metal with over a certain percentage of tin added to copper, or as an alloy of tin, zinc, and lead with copper. There is disagreement regarding the interpretation of this term. Baekdong, which started to appear in the literature of the Three Kingdoms Period, has been steadily seen through the Goryeo and Chosun Dynasties to the modern period. It has been used in various ways, according to each age and culture, from the symbol of the office to trading goods, daily life goods, and money. In the literature, baekdong's alloying material is not only copper and nickel, which are currently defined as alloys, but it is the same in that copper is used as the base metal of the alloy, although it varies slightly from generation to generation. In addition to copper, tin, zeolite, and emerald, zinc and lead also appeared. It was found that baekdong, which means alloy, and baekdong, which means white metal, were mixed. Nickel, which is the alloy material of baekdong as it is currently defined, is a metal with a relatively high discovery time and is widely used as a material for modern industrial fields. Nickel was introduced into Korea at the end of the Joseon Dynasty, but its use is not known in detail. In this study, we examined the acceptance and use of nickel-based baekdong in articles of modern newspapers and in statistical data. Based on the experience of craftsmen, we estimated the period when nickel-based alloys were used in crafts. Material is a direct factor in the development and deterioration of technology, and the development of technology is the basis for the changing of civilizations and cultures. In this context, this study was to investigate baekdong with the material of alloys as a starting point.

The Neolithic shell midden in Daejuk-ri, Seosan, is distributed on the gentle slope of a low hill close to the west coast. The bedrock of the area consists mainly of schist with various mafic minerals, but shows a partial gneiss pattern. The site consists of loamy topsoil and clay loam subsoil, and the degree of siallization is relatively low. Although the pottery excavated from the shell midden shares mostly similar features, a variety of shapes and patterns coexist. The surface colors, thickness and physical properties are slightly different. The pottery can be subdivided into three types (IA, IB and II) according to the composition of the body clay, the temper and the existence of a black core. Types IA and IB are colorless mineral pottery with a non-black or black core respectively. TypeII is colored mineral pottery with a non-black core. Type I pottery also contains non-plastic colored minerals, but type II contains a large amount of biotite, chlorite, talc, amphibole, diopside and tremolite, which include a large amount of Mg and Fe. The studied pottery contains a small amount of organic matter. Considering the grain size and relatively poor sorting and roundness of the non-plastic particles, the pottery appears to be made by adding coarse non-plastic tempers for special purposes to the untreated weathered soil around the site. The three types of pottery seem to have been incompletely fired in general. While type IB has the lowest degree of oxidation, typeII shows the highest degree of redness and oxidation. It can be interpreted that these differences depend on the firing temperature and the ratio of non-plastic particles. Through a synthesis of the minerals, geochemical data and thermal history, it can be determined that the firing temperature ranged from 600 to 700℃. The pottery types of the Daejuk-ri Shell Midden have slightly different production conditions, mineral compositions, and physical properties, but have undergone similar production processes with basically the same clay materials. The clay is almost identical to the composition of the bedrock and weathered soil distributed in the Daejuk-ri area. Currently, there is an industrial complex in the area, so it is difficult to confirm the soil and geological distribution of the site. However, it is highly probable that the area around the site was self-sufficient for the clay and tempers required for the production of the Neolithic pottery. Therefore, it can be interpreted that the group that left the shell midden in Daejuk-ri lived near the site, visited the site for the purpose of collecting and processing shellfish, and discarded the broken pottery along with shells.

This study examines the process of Korea's acceptance of the concept of Art Craft through research on ancient remains and relices (朝鮮古蹟調査) and a series of projects undertaken by the Japanese Government-General of Korea, and the traditions and canons of craft established in the process. Crafts defined in law referred to fine and exquisite techniques for creating antiques, or genres of art such as painting or sculpture. The Yi Royal Family Museum and the Museum of the Japanese Government-General of Korea spearheaded the popularization of the term "Mi-sul-gong-ye (Art Craft, 美術工藝)." The artworks displayed in these two museums visually embodied past traditions. In general, the term "craft" was frequently used to refer to ancient art, and crafts specifically became traditions to be protected and conserved by designation as legal treasures for display in museums. The establishment of traditions and canons of craft exerted a great influence on crafts produced during this era. The cultural policies and imperial tastes of Japan played a crucial role in this process. In previous research, scholars divided the concept of craft in the modern era into two categories: industrial craft and art craft. However the so-called "art craft" is not a homogeneous category. It includes both ancient art (antiques) and the pieces made in modern age. Ancient art became canonized and the basis of contemporary production. Moreover, features of contemporary craft were diverse. By subdividing concepts of art and crafts, which have hitherto been discussed collectively, this study will serve as groundwork for accurately understanding "invented traditions" and features of modern craft.

In this study observation records of the National Natural Environment Survey (2008-2012, 2014-2017) and the Korean Natural History Research Information System (KNHRIS) for the common kestrel (2013-2016) were consulted to determine the correlation of the distribution of kestrels in an area and the area's land use type. Distribution characteristics were studied based on data collected over the last 10 years (2008-2017). Findings show that the common kestrel is widely distributed between 4,407 sites registered in KNHRIS in the period of 2008-2012, 3,899 sites in 2014-2017, and 508 sites in 2013-2016. Relationship analysis was conducted for the altitude and urban planning factors of statistics based on a 2017 GIS check to determine the distribution characteristics. The birds' altitude was confirmed to range from 0 to 1,200 metersck but was most commonly observed at less than 100 meters. Above 200 meters, the rate of occurrence decreased rapidly. The rate of occurrence of the common kestrel was highest in Chungcheongnam-do province, followed by Gyeongsangbuk-do, Kyonggi-do, Jeollanam-do and Jeollabuk-do. As urban areas, green areas, commercial areas, and industrial areas the presence of swere positively correlated with the presence of kestrels, the rate of occurrence of the kestrel was higher in those regions. However, there was no significant relationship between the incidence of kestrels and housing construction or residential areas.
