The purpose of this paper is to estimate the external diseconomies of an unwelcomed facility on the nearby houses. The facility and the area studied are Dangin-Ri power plant in Mapo-Gu, Seoul and the residential district surrounding it respectively. The nearby housing prices have been changed according to the time and circumstances of the public announcements about the reconstruction or removal plans of the plant. These price changes are regarded as the capitalized values of the external diseconomies due to the plant. This study is based on the hedonic price theory in order to estimate the diseconomies in monetary value. The tools for the estimation are four models of multiple regression with the transaction price as the dependant variable and various housing characteristics including the external effects of the plant as the independent variables. The sample analyzed is 833 house transactions for the past 5 years in the research area. The facts found are as follows; First, the most suitable functional form for the estimation is confirmed to be the linear model. Second, there are significant differences in influence on the housing values among the independent variables, that is, locational characteristics, physical features, and environmental changes with time. Third, the external diseconomy is estimated as \80,137,807 in case that the plant would be reconstructed in the underground of the present site, whereon a substitutional public park would be constructed and as \59,142,248 in case that the plant would move away.

This study was a correlation study to analyze the effects of smartphone usage time on food choice perceptions and behavior in middle school students in Seoul areas. The subjects to be surveyed were middle school students attending junior high schools in Mapo-gu, Seoul. A total of 133, 102, and 102 students were in the first second, and third grades, respectively. The usage time of smartphones was the weekday and weekend usage time except for the call function. Food choice perception and its behavior as dietary habits were constructed referring to previous research and food balance wheels data for the correct dietary habits of the Ministry of Health & Welfare and Korean Nutrition Society. The food choice behavior was categorized into non-recommended food and recommended food. The results are summarized as follows. First, the longer the time spent on smartphones, the less favorable the perception of correct food choices. Second, the higher the dependence on smartphones, the less favorable the perception of correct food choices. Third, the correct perception of food choices has been shown to reduce food choices, known as non-recommended foods. In addition, proper perception of food choices has been shown to increase the choice of recommended foods. In conclusion, the usage time and reliance of smartphones of middle school students was found to affect the food choice behavior by lowering the perception of correct food choices. This research is expected to form the basis for the development of programs and educational materials that can be of assistance to adolescents who are experiencing difficulties.

Recently many local governments have carried out dong merger and abolition process to cope with rapidly changing administrative demand and environment. This administrative effort impacts substantially the locational characteristics of the existing dong offices which directly involve in the quality of local community life. In this paper, we attempt to analyze the location pattern of current dong community service centers (formerly, 'dong office') and suggest the optimal locations maximizing spatial accessibility. As an application, we examine the location pattern of the existing dong community service centers in Mapo-gu, Seoul. Moreover, we compare current spatial configurations with the optimally selected locations such as, a Median maximizing spatial efficiency, a Center maximizing spatial equity, and a Centdian exploring compromising solutions regarding the tradeoff between efficiency and equity. The analytical results present that each of dong community service centers was systematically evaluated in terms of spatial efficiency and equity and in general the community service center locations are not spatially optimized with respect to efficiency and equity, compared with the optimal locations.

Based on the current status of use of L-Commerce installed in the Yongsan Public Library and Mapo Lifelong Learning Center, this study suggested the direction of spatial design for the public library's makerspace with L-Commons model. To this end, we investigated the literature research on library makerspaces and the case studies of makerspaces installed in 25 public libraries in Korea and 18 public libraries in the US. And In-depth interviews and user surveys were conducted. The public library makerspace presented through this study should be an open space where everyone in the community can easily enter, break down barriers between all classes in the region, and lead to smooth communication. Second, it should be a learning, cooperation, and creative space where resources can be shared and cooperation for creative activities and projects can be carried out. Third, it should be a creative workspace where community members can turn ideas into physical things that anyone can't do elsewhere or work on something interesting.

This study examines changes in commercial space in Seoul from 1999 to 2016 by investigating operating periods of commercial businesses. This study finds that the characteristics of spatial changes in commercial districts are classified by the following two major points. First, the traditional CBD and Yeongdeung-po commercial districts show that both ages (survival duration) of operating commercial businesses and operating periods of market-exit businesses have changed to become longer than the average values of the two business types in Seoul. In contrast, the Gangnam and the Mapo commercial districts show that the operating periods of survived and closed commercial businesses have changed to become shorter over time. The difference suggests that survival-exit relations of businesses are closely related to the characteristics of each commercial district. In addition, this study shows that each commercial district has experienced dynamic changes in the intensity of commercial activities and the hierarchy of commercial space. Finally, this study indicates that public policies for commercial space should consider survival-exit dynamics of commercial activities in commercial districts.

Purpose: The study aims to demonstrate regional diagnosis methods and results combined with geographical information to expand the physical infrastructure related to community care services. To this end, the physical infrastructure for the core elements of community care was analyzed in terms of the fulfilment and access of facilities to derive the underserved elements and regions. Methods: Utilizes GIS network analysis techniques that can derive physical infrastructure service areas. Underserved elements are derived by comparing and analyzing the service area for each core element. Next, the underserved regions for each core element are derived through the overlapping of the set service area and the diagnosis population. Results: Among the physical infrastructure by core elements for community care, the housing support element was considerably weak, and the nursing care facility compared to health care was also analyzed to be weak. In addition, underserved regions by dong in Mapo-gu were deduced and presented for each diagnosed population. Implications: The discovery of underserved elements and underserved regions is meaningful as a diagnostic process that can derive the physical infrastructure that needs to be expanded urgently for the realization of community care and determine the priority projects and targets of the projects.

We found Urtica dioica L., an unrecorded alien plant, in the Han River basin of Korea. U. dioica is considered to be native to Europe, much of temperate Asia and western North Africa. This plant has been introduced to many other parts of the world. In Particularly, it reported as an invasive species from East Asia (Japan), Oceania and South America. This species is distinguished from related Korean taxa of the genus by its unisexual flower and dioecious plant species. In the Neighbor-Joining tree, U. dioica samples from the Han River Park (Sangam-dong, Mapo-gu, Seoul) and Yangjaecheon Stream (Daechi-dong, Gangnam-gu, Seoul) clustered into a clade consisting of a U. dioica s.s. Here, we provide a precise description, illustrations, a key to the related taxa, and photographs of its habitat.

Hydrogen is expected to be widely applied in most sectors within the current energy system, such as transportation and logistics, and is expected to be economically and technologically utilized as a power source to achieve vehiclebon emission reduction. In particular, the construction of hydrogen charging station infrastructure will not only support the distribution of hydrogen electric vehicles, but also play an important role in building a hydrogen logistics system. Therefore, This paper suggest additional charging infrastructure areas in Seoul with a focus on supply according to the annual average growth rate (CAGR), centering on Seoul, where hydrogen vehicles are most widely distributed. As of February 2022, hydrogen charging infrastructures were installed in Gangseo-gu, Gangdong-gu, Mapo-gu, Jung-gu, and Seocho-gu in downtown Seoul. Next, looking at the number of hydrogen vehicles by administrative dong in Seoul from 2018 to 2022, Seocho-gu has the most with 246 as of 2022, and Dongjak-gu has the highest average growth rate of 215.4% with a CAGR of 215.4%. Therefore, as a result of CAGR analysis, Dongjak-gu is expected to supply the most hydrogen vehicles in the future, and Seocho-gu currently has the most hydrogen vehicles, so it is likely that additional hydrogen charging infrastructure will be needed between Dongjak-gu and Seocho-gu.
