Based on the challenges encountered in the urban regeneration projects (general neighborhood-type) of Anjung District and Sinjang District in Pyeongtaek City, this study aims to explore the key factors of improvement measures for urban regeneration projects. Using the first survey conducted among shopping mall owners, employees, and residents, this study finds a significant level of awareness and very strong needs for urban regeneration projects. On the other hand, the overall satisfaction levels are observed to be low across the three factors: social, economic, and cultural. The second expert survey and the subsequent Analytic Hierarchy Process (AHP) analysis conducted for improvement measures reveal notable discrepancies in the prioritization of factors between administrative experts and practical experts. For the importance of administrative experts, the establishment of network-type regional governance was ranked first for the importance, followed by hosting events related to the U.S. military and long-term pre-market operations, and expanding exchange and cooperation between the U.S. Forces Korea and the community. For the importance of working-level experts, hosting U.S. military-related events and long-term pre-market operations was ranked first, while supporting U.S. military-related festivals and developing local natural landscape resources was ranked second. Our findings suggest the need for proactive measures such as attracting commercial facilities to stimulate demand from both the U.S. military and local residents, thereby revitalizing general neighborhood-type urban regeneration projects, developing programs for local tourism, and operating pre-market operations in the long run. Therefore, this study highlights the importance of regional government cooperation for urban regeneration projects.

The guiding research question of this paper is to discover 'why the UK could not develop a general structure in which transnational corporations were born during the end of the 19th ~ beginning of the 20th century like other countries'. In response to this question, although acknowledging its imperfections, the author would like to explore the causality in the context of 'Social Construction' which is reflected in the attributes of British society. As such, researchers are strongly recommended to take into account the actors' interests and the increased value effect of events which is driven by control power. This paper concludes that: firstly, not only was contempt for industrial capitalism prevalent in British society, the British government was unable to recognize the necessity of promoting policies for the development of transnational corporation. In addition, the increase in the clout of commercial-financial capitalists in the city of London along with the expansion of gentlemanly elites interfered with the transnationality of British companies. Secondly, the foundation of the political and economic structures in the UK experienced continuity and challenge simultaneously. Since the 1850's, the British social structure has been progressively characterized by the strengthening power of the commercial-financial elites in London, which resulted not in the transnationality of manufacturing but that of financial services. Finally, the configuration of the social network driven by the British elites consists of the actors' interests and control power in association with severance and connection. Unlike the complementarity of interests, in the initial stage, intended connection based on voluntary motivation between gentries and commercial-financial elites occurred in terms of control power. However, ultimately, the holding of power was transferred to the commercial-financial elites excluding the industrial capitalists and resulted in the reconfiguration of the social network.

Korea faces a wide range of problems in areas such as safety, environment, and traffic due to the rapid economic development and urbanization process. Despite the local governments’ efforts to deal with electronic civil complaints and solve urban problems, civil complaints have been on the increase year by year. In this study, we collected civil complaint data over the last six years from a small and medium-sized city, Jinju-si. In order to conduct a spatial distribution pattern analysis, we indicated the location data on the area through Geocoding after classifying the reasons for civil complaints and then extracted the location data of the civil complaint occurrence spots in order to analyze the correlation between electronic civil complaints and land use. Results demonstrated that electronic civil complaints in Jinju-si were clustered in residential, central commercial, and residential-industrial mixed-use areas—areas where land development had been completed within the city center. After analyzing the civil complaints according to the land use, results revealed that complaints about illegal parking were the highest. Regarding the analysis results of facility distribution within a 50m radius from the civil complaint areas, civil complaints occurred a lot in detached housing areas located within the commercial and residential-industrial mixed-use areas. In the case of residential areas(old downtown), civil complaints were condensed in the areas with many ordinary restaurants. This research explored civil complaints in terms of the urban space and can be expected to be effectively utilized in finding solutions to the civil complaints

This paper analyzes herd behavior observed in the loan market from 2001 to 2014 using a panel data on commercial banks including state-owned banks, domestic private banks, foreign banks, and Islamic banks. The paper finds evidence that herd behaviors of domestic private and foreign banks have been pronounced and long-lasting around the 2008 global financial crisis when state-owned banks did not show such a behavior. This result shows that since private banks tend to be keen on maximizing profits and avoid financial risks exposed by lending during a financial crisis, their lending decisions are not independent but dependent on whether other banks increase loans or not. On the other hand, Islamic banks do not show herd behavior during the financial crisis. This finding is consistent with earlier studies that Islamic banks have different characteristics, such as profit and operation mechanisms, from other private banks. Another interesting finding is that when it comes to rural loans, all the banks' herd behavior is short-lived and the herding indexes are quite volatile. This finding is attributable to distinct features of rural loans. Usually maturities of rural loans are shorter than city loans and related to the cycle of farming. Agricultural production is heavily dependent on unpredicted factors, such as floods and droughts, not previous year's production. Lastly, the paper finds a herding across bank type that state-owned, foreign, and Islamic banks follow domestic private banks'lending decisions.

인공습지는 자연이 가진 정화기작을 인위적으로 증가시키기 위하여 조성한 자연기반해법에 해당한다. 인공습지는 습지 내 식물, 미생물, 토양 등의 상호기작에 의하여 오염물질이 제거된다. 인공습지의 오염물질저감효율은 시설의 규모와 유량, 유입물질의 부하량 수리학적 부하량, 체류시간 등의 영향을 받게 된다. 일반적으로 인공습지 적정 규모는 유역 및 기상인자의 특성과 조성목적에 고려하여 산정된다. 본 연구는 전국 35개 지역에 설치된 54개 인공습지를 선정하여 모니터링을 수행하였으며, 2011년부터 2018년에 설치된 시설이다. 54개 시설 중 도심지역에 13개, 농업지역 25개, 공업지역 3개, 상업지역 3개, 축산 10개가 설치되어있다. 습지형태는 Cell형 자유수면형 인공습지(Free Water Surface, Cell-FWS), 유로형(Flow) 자유수면형 인공습지(Cell-FWS), Cell과 Flow형이 결합된 Hybrid-FWS, 수직흐름형 인공습지(vertical flow constructed wetland)와 수평지하흐름형 인공습지(vertical flow constructed wetland)가 결합된 HYBIRD 형 습지로 구분된다. 연구결과, 일반적으로 SA/CA 비율이 클수록 오염물질의 저감효율은 증가하는 것으로 나타났다. 오염 물질별 인공습지 규모를 비교할 경우 저감효율 60%에서 인공습지의 규모는 유기물>영양염류>입자상물질 순으로 나타났다. 목표 제거효율 60%에서 SA/CA 비는 BOD에서 약 3.2%, COD에서 2.5%, SS에서 1.9%, TN 2.5%, TP 2.3%로 나타났다. 입자상물질인 SS는 유기물 및 영양염류에 비하여 유역면적 대비 시설면적이 가장 적게 나타났으며, 유기물질 제거에 큰 시설규모가 필요한 것으로 나타났다. 따라서 인공습지 설계시 유역 토지이용 및 강우특성을 고려하여 적정한 수질과 유량모니터링이 필요하며, 이를 토대로 목표 오염물질 선정이 중요한 것으로 나타났다. 또한, 농업지역의 최적화된 인공습지 위치는 임야가 20~30%, 밭이 20% 이하, 논이 10~50%를 포함하는 곳이 적정한 것으로 평가되었다. 도시지역 인공습지는 도시면적이 증가할수록 효율이 크게 변하지 않기에 가용위치가 적정한 위치로 평가된다. 인공습지의 효율은 유역의 세부 토지이용에 크게 의존하는 것으로 평가되었다. 따라서 인공습지 설계시 농업지역에서는 임야, 밭 및 논의 적정면적을 고려하여 인공습지 위치가 결정되어야 하는 것으로 나타났다.

Worldwide Electric Vehicle (EV) sales are rapidly increasing. But in many cases, charging locations can be found within or near downtown area of the city which makes EV users living outskirts of the city very difficult to establish their daily EV charging routines. In order to improve this situation, we have come up with a daily EV charge service connected with convenience stores and restaurants within reach of most EV users living in South Korea. We aim to allow users to charge their EVs while they shop and eat, just as if they charge their smartphones at cafes and restaurants. We have gone through user diary research and focus group interview research to figure out current user's concerns regarding charging and maintenance of EVs and applied the findings to our proposed service design.

The study shows solutions of long-term unexecuted urban park and activation plans to facilitate the business promotion of Private Park Developers. This study conducted a feasibility analysis to determine if the business of a special case is applicable. The result of this study is as follows about three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park. First, the three long-term unexecuted urban parks in Gwangju Metropolitan City's City Park are the forest type Neighborhood Parks. Businesses of a special case's park developing cost(average 0.4%) have a relatively low percentage. It is most affected by Land Compensation(average 33.8%) and building construction expenses(average 59.1%). Second, long-term unexecuted urban parks' Land Compensation and building construction expenses seed capital are excessive. The Bongsan Park balance floor space index is 179 percent; a reasonable profit floor space index is 220 percent. The Mareuk Park balance floor space index is 351 percent; a reasonable profit floor space index is 420 percent. The Jungoe Park balance floor space index is 327 percent; a reasonable profit floor space index is 400 percent. Third, to facilitate the business of special cases in deliberating, Bongsan Park should change its second class general residential area. Jungoe Park must change the quasi-residential area and semi-residential area. Mareuk Park must change the general commercial area. In this way, the feasibility of promoting private park projects will be improved.

We analyzed the PCDD/Fs and PCBs in human milk samples from a city and an industrial region by HRGC/HRMS. The average concentrations of PCDD/Fs and PCBs in human milk were 15.13 TEQ pg/g fat and 5.64 TEQ pg/g fat respectively. We discovered two kinds of homologue distributions. We compared congeners of each distributions with those of the commercial PCBs products. The daily intake of infant was predicted to be 60 TEQpg/kg/day according to the mean concentration of PCDD/Fs based on primipara. This value is much higher than the estimated range for background exposure to adult in the USA (1-3 TEQ pg/g fat).
