  • After city of Busan has been entered to the aging society in 2000, the city has the highest aging rate among 7 representative cities in 2011. Moreover, while entire population and number of average household are decreasing, over 65 years old of elderly population is rapidly increasing. So, it is possible to enter the super-aged society, where aging rate would be about 20% after 2020. The purpose of this study is that older housing-related analysis is consisted of dong-unit, and this led microscopic analysis has become necessary. Surveys from 2000 through 2010, census aggregate (output area) unit of spatial analysis was conducted. Take advantages of this, aging population and area, soaring area, high-density areas, such as the region of interest were primary extracted, and microscopic location and spatial distribution patterns were analyzed. Upon analysis, aging population is concentrated in the city and adjacent area, the highlands, and 10 years of increasing rate was more than 30 times in certain aggregate. Regarding the characteristic of these areas, the original city center, Busan, especially concentrated and intensified in aging population. Also, 2000 to 2010, the overall distribution pattern of Busan has identified aging population that is increasingly being distributed. This is the result, which is confronted with previous research result. Entering a super aged-society for the future is accordance with migration of social costs and improve the quality of life of elderly. And this could be the basic information to use the spatial dimension for the corresponding.

  • Recently, the size of currently-researched components and devices reduces nano-scale. Thus, it is important and emphasizes the analyses of physical properties in nano scale. Especially, the mechanical properties are not over micro-scale components but nano-scale components with different characteristics that has been reported. However, most analytical methods for currently studying in nano-scale are related to spectroscopy and electronics, affected the limitation of viewing size that these methods give only average information. In this research, the representative nanotribology analyses, nano-indenter study the physical and mechanical properties of W-N thin film for nano region and nano depth within nano-scale that the thickness of W-N diffusion barrier has less than tens of nanometers. The Scanning probe microscopy (SPM) study the surface image. From these results, the hardness of W-N thin film underneath the nano-surface decreased from 57.67 GPa to 9.1 GPa according to the increase of nitrogen gas flow. The elastic modulus of W-N thin film underneath the nano-surface also decreased from 575.53 GPa to 178.1 GPa.

  • The purpose of this study is to provide the baseline data for conservation and management of the ecosystem of urban forest by surveying and analysing the vascular plants distributed in Hwangseong Park, Gyeongju-si. The results of the survey of vascular plants from April 2018 to May 2020 were summarized as 338 taxa including 78 families, 222 genera, 296 species, 5 subspecies, 18 varieties, 6 forms, 4 hybrids and 9 cultivars, and 110 taxa of planted species and 235 taxa of native species were identified. The representative planting species was Liriope muscari. The 7 taxa of rare plants and 5 taxa of Korean endemic plants were investigated. The specific plants by floristic region were totally 24 taxa, which were 1 taxa of grade V, 4 taxa of grade IV, 7 taxa of grade III, 4 taxa of grade II and 8 taxa of grade I. The 57 taxa of naturalized plants and 6 taxa of invasive alien plants were showed. In particular, Chionanthus retusus represent traditional landscape trees in Korea and have high ecological value. Therefore, the old trees of Chionanthus retusus will have to be managed by assigning a number for each individual. The invasive alien plants will need periodic control and development of programs that can work in conjunction with civic groups.

  • Since the evaluation of its intellectual activities and abilities is done by curator's capabilities, planning exhibition is very important as the final result achieved by their own knowledge, information, and research. ARPA(Advanced Research Project on Arts) is suggested as the system which enables curators responding simultaneously to the society in the times, based on its special characteristics. If this system settles well, which means that the curators at NMCA(National Museum of Contemporary Art, Korea) play their roles as the professionals in each of their fields, the goal of consolidating the status of museum as the representative national museum, and building up competent department of curators, will be achieved at the same time. To clarify above, the curators set up the various assignments of research about the types of arts such as painting, Korean painting, sculpture, installation, new-media, design, craft, photogarphy, architecture, etc. And they establish the art objects classified by the regions, such as the Northern American, Southern American, European, Asian, and other Third World countries. They elaborate art objects more on the history, the work, the artist, and the issue of contemporary art. Furthermore, when the curators devote deeper study to those research subjects, they can have the opportunities to design an exhibition upon the research. Today, the museum of art is 'The Place for Communication and Encounter', it is regarded important to share the aesthetical, creative values with current artists, and to understand mutually with the spectators. It is needed to improve the curator's work, in order to meet the demands of the times and even to advance. Because the form of 'exhibition' is the tool that reveals the identity NMCA aiming at, the motivation, the development, and the realization should be leaded by the curators, who are the mainstream of the museum. ARPA is a system for identifying the exhibition like mentioned above. The main purpose of this system is to produce synergy effect, having the researching, collecting work in liaison with planning exhibition. ARPA will be able to improve the quality of exhibition through the way of developing the exhibition, passing through the stable process in the long run. So far, I have referred to a new paradigm of the exhibition design at NMCA via ARPA. Yet, there still remain missions in reality, such as analyzing the previous exhibition and reshuffling personnel and system, which should be done. When these matters settled, these plans would be suggested practically. At this point, it is the most significant that NMCA is attempting to let others aware of the importance of exhibition planning based on research. when the ARPA and exhibition planning is conjoined together successfully, the competent exhibition will be achieved, which can offer a meaningful exhibition to the art world, strengthen infra structure thru exchanging with public museum in the region, and eventually, establish a network with museum in foreign countries.

  • This research had selected current rural village development projects with the representative meaning of rural regional development projects in order to analyze results of projects and various policies of the government to enhance the quality of resident life and to develop rural regions. For the analysis, this research had selected 2 districts of the case study in Gyeongnam-province and Jeonnam-province, respectively. In the result of the satisfaction analysis on the projects, it was considerably difficult to analyze satisfaction degree by using a clear distinction of each region type when promoting overall project. However, this research confirmed that there were some differences about residents' understanding of the project and satisfaction degree in the process of projects according to the regional characteristics (rural and mountain areas). In general, two districts' residents of rural areas expressed relatively more negative feedbacks in process of the project compared to two district residents of mountain areas. This research suggested that it is needed to have residents' understanding of the project, a restoration of village community spirit to help each other and to cooperate, fostering a desirable leader, establishing effective village regulations, transition into an open and inclusive attitude, promoting rural village development project, and realization of the operating method in order to have an amicable project process in the future.

  • The Korean Mask-Dance Theatre has been developed closely related to Korean Shaman rituals. As many scholars noticed, the performers of the Mask-Dance Theatre were closely related to the Shaman family. In addition, there are mask-dance performances in actual shaman rituals. and are the representative performances among them. This essay intends to compare these two mask-dance performances in the shaman rituals to the similar performance of Old Grandpa and Grandma episode in the regional Mask-Dance Theatre. This study would bring us further in proving the close relation between the shaman ritual and the Mask-Dance Theatre. is one episode, Keori, in the shaman ritual of 'Baeyeonsin-kut' and 'Taedong-kut' in the mid-west seashore area. 'Taedong-kut' is the village shaman ritual for fertility and prosperity, while 'Baeyeonsin-kut' is a private shaman ritual for a large catch of the ship. is held in the later part of the whole shaman ritual since the later part tend to be more for entertainment than actual ritual. The story of is very similar that of in Pongsan Mask-Dance Theatre of the mid-west region. In addition, some of their dialogues are very similar. Only the later part is different. These similarities indicate that the Mask-Dance Theatre, which came into being in later period than the shaman ritual, has likely taken the story motif of the shaman ritual. is also a performance in the shaman ritual of east coasts. is more elaborate and recreational than of the west coasts. is also performed near the end of the ritual, and sometimes it is not performed at all. This indicates that has little ritual meaning left. When we compare it with the regional Mask-Dance Theatres such as Keosung Okwangdae, Tongyong Okwangdae, and Suyong Yaryu, the structure and the story lines are also very similar. It is a question why only the motif of the Grandpa and Grandma isfound both in the shaman ritual and the Mask-Dance Theatre. Many other motifs of other episodes in the Mask-Dance Theatre are not found in the shaman rituals. It seems that the Grandpa and Grandma motif is related to the ur-belief in fertility. In other words, this motif seems to be originated from the old belief in the fertility couple of Chonha Taechanggun and Jiha Yeochanggun. The shaman ritual for fertility first picked up this motif, and then the mask-dance theatre also adapted this motif for its recreational purpose. When we compare with , still has more aspects of fertility ritual, while lost its ritualistic meaning and its main purpose is to develop dramatic needs. and are invaluable existent performances to prove theatre's origin in ritual. The existence of mask-dance performances in the shaman rituals shows us the transit performance between theatre and ritual.

  • Various studies have been conducted to analyze the location appropriateness and capacity of shelters. However, research on how to select new shelters is relatively insufficient. Since the shelter is designated in case of emergency, it is also necessary to efficiently select the location of the shelter. Therefore, this study presented a method for selecting the location of the shelter using network analysis that has been used to analyze the location appropriateness of shelters and genetic algorithm which is a representative heuristic algorithm. First, the network analysis using the existing civil defense evacuation facility data was performed and the result showed that the vulnerability of evacuation has a high deviation by region in the study area. In order to minimize the evacuation vulnerable area, the genetic algorithm was designed then the location of new shelters was determined. The initial solution consisting of candidate locations of new shelters was randomly generated and the optimal solution was found through the process of selection, crossover, and mutation. As a result of the experiment, the area with a high percentage of the evacuation vulnerable areas was prioritized and the effectiveness of the proposed method could be confirmed. The results of this study is expected to contribute to the positioning of new shelters and the establishment of an efficient evacuation plan in the future.

  • Purpose: UAV-based photo measurements are being researched using UAVs in the space information field as they are not only cost-effective compared to conventional aerial imaging but also easy to obtain high-resolution data on desired time and location. In this study, the UAV-based high-resolution images were used to perform the land cover classification. Method: RGB cameras were used to obtain high-resolution images, and in addition, multi-distribution cameras were used to photograph the same regions in order to accurately classify the feeding areas. Finally, Land cover classification was carried out for a total of seven classes using created ortho image by RGB and multispectral camera, DSM(Digital Surface Model), NDVI(Normalized Difference Vegetation Index), GLCM(Gray-Level Co-occurrence Matrix) using RF (Random Forest), a representative supervisory classification system. Results: To assess the accuracy of the classification, an accuracy assessment based on the error matrix was conducted, and the accuracy assessment results were verified that the proposed method could effectively classify classes in the region by comparing with the supervisory results using RGB images only. Conclusion: In case of adding orthoimage, multispectral image, NDVI and GLCM proposed in this study, accuracy was higher than that of conventional orthoimage. Future research will attempt to improve classification accuracy through the development of additional input data.

  • This study examined the physical attributes and heat treatment characteristics of glass beads excavated from the Gimhae area, which is the location of Geumgwan Gaya. This enabled classification of surface characteristics of the beads based on the investigation of the color, size, and shape. The glass beads were classified into eight color systems, with purplish-blue beads as the representative color. Bead size was categorized into three types depending on the outer diameter and how it increased over time. Bead shapes were categorized as round, tubular, or doughnut-shaped based on the inner diameter and length, with round being the typical shape. According to the degree of heat treatment, there are three types of cross-section for glass beads that are manufactured by the drawing technique, most of which are the HT-III type. In addition, it is estimated that the heat treatment technology has more considerable effects than other methods. Through non-destructive analysis, the chemical composition was obtained and categorized as flux, stabilizer, and colorant. Analysis confirmed the presence of 63 and 9 pieces in the potash and soda glass groups, respectively. Overall findings from the study highlighted a correlation between the chemical composition and the external factors such as color, size, shape, and manufacturing technology of glass beads recovered from Geumgwan Gaya, revealing characteristics related to that time and region.

  • This study evaluated the economic feasibility of facility farms according to the introduction of the ultra-high density pot cultivation (UHDPC) for mango. The basic model was selected as a representative farmhouse case in the Jeonnam region, and seven scenarios for conventional crops were tested. The economic feasibility of crop switching was analyzed through partial budget analysis (PBA). The PBA analysis results were supplemented by adding a sensitivity analysis and a break-even point (BEP) analysis. As a result of the analyses, it was found that crop conversion was economical because the increase in the profit coefficient was greater than the increase in the loss coefficient due to the introduction of mango for all conventional crops. The economics of introducing mango was more sensitive to changes in gross income than to changes in cost items. The results show the detailed conditions of crop selection according to the conditions and preferences of individual farms by presenting the direction of increase and decrease by budget item and information on the amount of increase or decrease. In particular, the BEP analysis result, which is about half of the farms case, is significant in that it presents the minimum target value according to production and market risks.
