The purpose of this study was to investigate heat resistance for union type SMD inductor core. The samples was produced with process 5 step. In this study, it analysis heat resistance of SMD(Surface Mounted Device) inductor core and it get electric field only exist inside of SMD core. Therefore electric fields do not affect any device and equipments. These results are very important to design data acquisition system(several test equipments such as temperature, impedance, and current test), because data acquisition system can place under the SMD Inductor core. So, it can be decrease their test error due to electric field.

Memory is a mental activity for the future rather than the past, and the responsibility for restoring the memory rests on the current intellectuals. In this context, the library must demonstrate how it contributes to local development by restoring memory and analyzing social roles and functions. Based on the contributions of local development of public libraries as background information and through literature case studies, field surveys and interviews. This study has logically demonstrated local development to the local economic development, regenerating and promoting local culture, and forming a community in the open-port cities of Busan and Incheon. Nevertheless, the contribution of local development in terms of economic, cultural and community formation cannot be perfect. Subsequent research that reflects the historical geography and architectural arts of the library itself, and the perception and value of use of local residents is necessary.

Culture is an indispensable element in modern society in improving the quality of life for city dwellers and stimulating the urbanization. The conspicuous emergence of cultural cities, which is a new paradigm, can be understood in that context. Global cities are pursuing cultural cities, and autonomous regions in Korea are also pushing ahead with the urbanization which combines cultural elements. Specifically, Nam-gu of Incheon has set an example of successful cultural city for other autonomous regions. The cultural environmental policy of Nam-gu is deemed to have retained the infrastructure, cultural urban landscape and living space, and a plenty of contents. The real significance of cultural city lies in the pursuit of sustainable urban development as a culture-friendly city. For that, the direction of cultural environmental city has to be firmly set, and related law and system should be strengthened. Above all, it is critical to pursue human-oriented cultural city by showing citizens what roles they have to play, setting the right direction, and improving the partnership.

The objective of this study is to describe the influence of railway and railway station on the change of city structure in Korea in the early 20th century. In the 1900s, railway was constructed in Japanese concessions and in new pore cities such as Incheon, Busan, and Wonsan. In the 1920s, railroad construction became related with the cities, which could produce the corps. In the 1930s, railroad also became related to the colonial industrial cities. Traditional city structure was then completely changed because new city structure was focused on not Seoul but Japan or harbors towards Japan. So Korean cities, which were netted by railway, had become the subsystem of Japan in the early 20th century. Korean cities have developed on the basis of this system until 1945. For example, the twelve main cities were chosen through the relationship with Japanese life, and the provincial office governments moved near railroad stations. However nowadays, these cities have possibilities of being international cities, such as Incheon and Busan, because of the extroversion of these cities.

The purpose of this study is to review and evaluate the proper planning for 2030 Incheon Urban Parks & Green Space Master Plan. Some of the plans are aimed at multiple small districts within the city's old town, as local governments are planned to be sub-subsidized by Incheon Metropolitan City. However, these plans have become simple plans for each district and therefore find it difficult to collect from the perspective of the using system of the residents who are directly used. First, the construction of the urban park and green space network requires the construction of a service using system that can be felt by the users. Second, the basic idea of each district planned as the detailed strategy of the master plan should be planned through consultation with nearby the district. Third, specific targets and directions for the urban park and green space plan through the urban development project are needed.

Ground subsidence in urban areas is mainly caused by anthropogenic factors such as excessive groundwater extraction and underground infrastructure development in the subsurface composed of soft materials. Global Navigation Satellite System data with high temporal resolution have been widely used to measure surface displacements accurately. However, these point-based terrestrial measurements with the low spatial resolution are somewhat limited in observing two-dimensional continuous surface displacements over large areas. The synthetic aperture radar interferometry (InSAR) technique can construct relatively high spatial resolution surface displacement information with accuracy ranging from millimeters to centimeters. Although constellation operations of SAR satellites have improved the revisit cycle, the temporal resolution of space-based observations is still low compared to in-situ observations. In this study, we evaluate the extraction of a time-series of surface displacement in Incheon Metropolitan City, South Korea, using the small baseline subset technique implemented using the commercial software, Gamma. For this purpose, 24 COSMO-SkyMed X-band SAR observations were collected from July 12, 2011, to August 27, 2012. The time-series surface displacement results were improved by reducing random phase noise, correcting residual phase due to satellite orbit errors, and mitigating nonlinear atmospheric phase artifacts. The perpendicular baseline of the collected COSMO-SkyMed SAR images was set to approximately 2-300 m. The surface displacement related to the ground subsidence was detected approximately 1 cm annually around a few Incheon Subway Line 2 route stations. The sufficient coherence indicates that the satellite orbit has been precisely managed for the interferometric processing.

Owing to global climate change, the global resurgence of vector-borne infectious diseases and their potential to inflict widespread casualties among human populations has emerged as a pivotal burden on public health systems. Tsutsugamushi disease (scrub typhus) in the Republic of Korea is steadily increasing and was designated as a legal communicable disease in 1994. The disease is a mite-borne acute febrile disease most commonly contracted from October to December. In this study, we tried to determine the prevalence of tsutsugamushi disease transmitted by chigger mites living on rodents and investigated their target vector diversity, abundance, and distribution to enable the mapping of hotspots for this disease in 2015. A total of 5 species belonging to 4 genera (109 mites): Leptotrombidium scutellare 60.6%, L. pallidum 28.4% Neotrombicula tamiyai 9.2%, Euschoengastia koreaensis/0.9%), and Neoschoengastia asakawa 0.9% were collected using chigger mite collecting traps mimicking human skin odor and sticky chigger traps from April to November 2015. Chigger mites causing tsutsugamushi disease in wild rodents were also collected in Hwaseong for the zoonotic surveillance of the vector. A total of 77 rodents belonging to 3 genera: Apodemus agrarius (93.5%), Crocidura lasiura (5.2%), and Micromys minutus (1.3%) were collected in April, October, and November 2015. The most common mite was L. pallidum (46.9%), followed by L. scutellare (18.6%), and L. orientale (18.0%). However, any of the chigger mite pools collected from rodent hosts was tested positive for Orientia tsutsugamushi, the pathogen of tsutsugamushi disease, in this survey.

Today, the paradigm of education is changing from teacher-centered, facility-centered, supplier-centered to student-centered, people-centered, and user-centered. In 2019, the Ministry of Education promoted the school space innovation project to provide a school space as a balanced life space, such as learning, play, and rest, through educational activities led by students, who are the leaders of the future society. Based on this, Incheon Metropolitan City Office of Education prepared a manual for practice while carrying out a project to build a future classroom. In those projects 'user participatory design' is applied as a new design approach and facilitators play an important role as experts in the process of user participatory design. However, it is different from the guidelines by the Ministry of Education in terms of facilitator role; facilitator in Incheon's future classroom projects can be in charge of designer part. This was possible because the design scope was limited to the classroom space and the construction permit work was not applied, and the Incheon Metropolitan City Office of Education seems to be able to successfully implement the plan derived through 'user participatory design' under the responsibility of the facilitator. However, this may be considered to be inconsistent with the basic purpose of the school space innovation project. In the case of the school unit project, it is considered that more systematic supplementation is necessary.

The purpose of this study is to establish common indicators that constitute a "low-carbon green city" and determine their priorities from the perspective of Incheon Metropolitan City with a view to help develop its climate change strategy strategic city. Several major cities, domestic and overseas, were benchmarked to come up with preliminary indicators consisting of six areas, twenty two planning factors, and 74 indicators. In order to evaluate the validity and relevance of preliminary indicators, expert FGI (Focus Group Interview) was conducted that changed the numbers of final indicators to six areas, twenty two planning factors, and 82 indicators. Finally, AHP (Analytic Hierarchy Process) was conducted to assign relative importance (i.e. weights) to each indicator. Through the layering process of AHP, the upper category of "field" and lower category of "planning factors" were set up as policy prerequisites for constructing a low-carbon green city (6 fields, 22 planning factors). The AHP results for the first level (fields), green city space was ranked first, followed by energy and resource circulation, green traffic, ecological preservation, green logistics, and governance. Among all planning factors, land use, energy efficiency, traffic system improvement, location planning, securing of ecological area, efficiency of logistics, and cooperative organization showed the highest priorities.

This study aims to analyze tourist inflow trends and consumption patterns using a geographic information system and big data analysis system. Songdo Central Park and Chinatown were selected among the major tourist destinations in Incheon, and floating population analysis and card sales analysis were conducted for one month in June 2017. The number of tourists visiting Songdo Central Park from metropolitan cities across the country was highest in the order of Incheon Metropolitan City, Gyeonggi-do, and Seoul Metropolitan City, and the proportion of foreign tourists was the highest in China. The number of card consumption used by Chinatown tourists was 12.4% higher for men than for women, and the amount of card consumption was also higher for men by 18%. This study has implications for proposing a strategic plan for tourism policy by analyzing the inflow trend and consumption pattern of tourists and deriving major issues in the establishment of tourism policy. Based on this study, it is expected that it can be helpful in improving the construction of tourism infrastructure in the future.
