The purpose of this paper is to develop a space program of the new community center in multi-family housing. The community center defined in this study is a communal facility which integrate cultural and welfare facilities and activity programs into a complex. Through the analysis of the community programs and spaces for multi-family housing community, a new community center program is proposed. And basic area guidelines are proposed through the making of the space modelling of the important area of the center. According to the guidelines, more spaces compared to the present standards and conditions are needed for a new community center. However, the adjustment of area regulation is essential, considering the fast changing trend of resident's social needs. A new regulation system that controls the total area of function spaces of a community center, rather than controlling each function and area, is required. This kind of system makes it possible to decide programs freely within the limit of total floor area regulation by neighborhood's characteristics and residents'preference.

The study is about developing of armor design for the children's experience with Gaya armor in museums. The aim of this paper is to combine the culture of Korean traditional armor with the development of cultural products through the research about the relic of Gaya and the analysis of the problem about the status of the operation for children's experience. The current problems of Gaya armor for the children's experience are discrepancies in the material, structure and configuration of the traditional Gaya armor in regards to the aspects of the education and; unsuitability for safety and operation of the outfit in regards to the aspects of the function. Therefore, this paper presents 10 different styles of armor design in consideration of the educational aspects and functional aspects, and this paper confirms the value of the traditional Korean armor by reaffirmation to artistic possibilities and merchantability of Gaya armor.

Synonym means that the conceptual meaning of the word is the same or similar while other meanings or function of language difference may exist. That is two or more identified names correspond with one sense and have the words with minor difference. Words with synonym relation are a set of same meaning but conceptual area or emotional color, language function can be identified. Therefore, the core research of synonym is the difference analysis and in general difference analysis is progress in the three aspects of Meaning, Pragmatic, and Semantic. However, the difference analysis is the most important. In this paper, the set of meaning item of synonym word 'Attack' is 'zheng', 'fa', 'tao', 'qin', 'xi'. We compare the meaning of five verbs and analyze the difference and characteristics.

In this paper, we maintain that case makers '에e' and '에게ege', and '에서eseo' and '에게서egeseo' are not two separate morphemes but are simply allomorphs of the same morphemes respectively. When '에e' and '에게ege' are used as a dative marker, they show exactly the same semantic function and are in complementary distribution in relation to the semantic features of their preceding noun; that is, if the preceding noun is an animate noun, '에게ege' is used and '에e' is used if not. Also, '에게서egeseo' and '에서eseo' as ablative and locative case makers show exactly the same semantic function and show complementary distribution depending on whether the preceding noun is animate or non-animate. Therefore, we assume that these markers are semantically conditioned allomorphs.

This study examined whether popular music lyrics, the new research topic, reflect changes in Koreans' cultural orientation and whether individuals' cultural orientation is related to the genre of popular music that they prefer. In Study 1, we content analyzed popular music lyrics from 1980 to 2018 to see if Koreans' cultural orientations changed over time. The analysis showed that as the release dates approached the 2010s, the lyrics expressed the ideal attitudes of individualist cultures more frequently than those of collectivist cultures; this suggests that Koreans have gradually become more individualistic over time. In Study 2, we examined the relationships between individuals' cultural orientations, preferences for various genres of popular music, and functions of music. The analysis showed that people with more collectivistic attitudes tended to prefer mid- and low-arousal music, such as Ballads and Rap/Hiphop, while those with less collectivistic attitudes preferred high-arousal music, such as Rock/Metal. This result is partly consistent with the hypothesis that collectivistic people would prefer lower to higher arousal music. In addition, our analysis showed the strongest positive relationship between collectivism and the social function of music; this result can be interpreted as indicating that collectivistic people use music to maintain good interpersonal relationships. This paper concludes by discussing the implications of these findings, the limitations of this study, and directions for further research.

This study focuses on the emergence of "hobby-preneurs" and the ways in which they are transforming the virtuous cycle of arts and cultural ecology. The hobby-preneur pursues and expands his or her favorite hobby into a professional job and/or arts business. Hobby-preneurs are the new driving force in the arts and cultural industry. Their activities enhance the arts as a public good even as they build valuable social capital for arts organizations and have a profound impact on supply and demand in the arts and cultural marketplace. Thus we found that by injecting and potentiating certain values that professional artists cannot directly deliver to arts consumers, hobby-preneurs function as major intermediaries in the virtuous cycle of arts and cultural ecology. To understand more about these emergent actors we examine their personal, social, and economic values and how these values guide their arts-related activities and thereby impact the ecology of the arts and cultural sector. In this study we use a phenomenological approach to investigate five hobby-preneurs and the particular ways their acquisition of professionalism is transforming the arts education node of the virtuous cycle in the creative sector.

The warming of the climate is increasing the damage caused by termites to wooden buildings, cultural properties and houses. A group removal system can be installed around the building to detect and remove termite damage; however, if the site is not visited regularly, every one to two months, you cannot observe whether termites have spread within, and it is difficult to take prompt effective action. In addition, since the system is installed and operated in an exposed state for a long period of time, it may be ineffective or damaged, resulting in a loss of function. Furthermore if the system is installed near a cultural site, it may affect the aesthetic environment of the site. In this study, we created a detection system that uses wood, cellulose, magnets, and magnetic sensors to determine whether termites have entered the area. The data was then transferred to a low power LoRa Network which displayed the results without the necessity of visiting the site. The wood was made in the shape of a pile, and holes were made from the top to the bottom to make it easier for termites to enter and produce a cellulose sample. The cellulose sample was made in a cylindrical shape with a magnet wrapped in cellulose and inserted into the top of a hole in the wood. Then, the upper part of the wood pile was covered with a stopper to prevent foreign matter from entering. It also served to block external factors such as light and rainfall, and to create an environment where termites could add cellulose samples. When the cellulose was added by the termites, a space was created around the magnet, causing the magnet to either fall or tilt. The magnetic sensor inside the stopper was fixed on the top of the cellulose sample and measured the change in the distance between the magnet and the sensor according to the movement of the magnet. In outdoor experiments, 11 cellulose samples were inserted into the wood detection system and the termite inflow was confirmed through the movement of the magnet without visiting the site within 5 to 17 days. When making further improvements to the function and operation of the system it in the future, it is possible to confirm that termites have invaded without visiting the site. Then it is also possible to reduce damage and fruiting due to product exposure, and which would improve the condition and appearance of cultural properties.
