In the city of Dongducheon, the population is decreasing and aging and the United States Army is relocating its base and soldiers gradually. Despite that the sources of economic vitality in the city fade out, industrial bases, in particular, manufacturing industries are lacking in the region. The current industrial ecosystem has shortcomings; most of the firms are small and they are located individually. It is expected that the new Dongducheon National Industrial Park could overcome the issues, To provide a basis for Dongducheon National Industrial Park, this study analyzed the industrial ecosystem of Dongducheon and the neighboring cities and regions. An input-output analysis suggests that the following manufacturing sectors have advantages: textiles, leather, basic metals, fabricated metal products, electronic components, computers, optical instruments, and electrical equipment. Moreover, it is recommended that materials, components, and equipment manufacturing industries can be invited to Dongducheon National Industrial Park. Some current national industrial policies can be also in consideration to set the future goal of Dongducheon National Industrial Park. First, reshoring firms outside South Korea can be pursued with the convergence of manufacturing and service industries and the introduction of a smart factory. Second, Dongducheon-style smart green industrial park can be provided as an objective model in a line with the Korean New Deal (Green, digital, and Balanced Regional Development policies). Deregulation in Dongducheon and North Gyeonggi-do is also a big task for the regional development in the region. There have been many regulations for the Seoul metropolitan region, military, and the United States Army bases. To overcome the issue, diverse deregulation methods in limited geographic areas should be considered gradually. This study proposes some policy suggestions at the three different scales: Dongducheon-si, Gyeonggi-do, and the national government. First, the city should pursue the agglomeration of manufacturing industries, and a regional labor market and industrial network, then finally high-tech industries. The virtuous circle will be made not by a short-sighted policy, but by a long-term policy. The current textile industry in the region should be upgraded to the smart textile industry with the convergence of other materials. If so, it can take an important role for the medical and preventive equipment industries which prevents COVID-19 and future epidemics and pandemics. Second, Gyeonggi-do can match Dongducheon National Industrial Park with another in the south Gyeonggi and support the balanced regional development in the province. Moreover, inviting an anchor company to the region is in the province"s decision and support. The national government should support Dongducheon and the bordering region as a step for inter-Korean economic cooperation while avoiding the dichotomous view of metropolitan and non-metropolitan regions.

김영롱,오치혁,양민재 대한췌장담도학회 2023 대한췌담도학회지 Vol.28 No.1

Gallbladder cancer is the most common cause of hilar biliary obstruction; however, it rarely causes combined biliary, duodenal, and colon triple obstruction. In this case, the quality of life for a patient with recurrent gallbladder cancer with combined duodenal, colonic, and biliary obstruction was improved by endoscopic and endosonographic palliation, despite its technical difficulty and complexity. Seven metal stents were implanted one by one using only endoscopic methods. Successful stent-in-stent placement and endoscopic ultrasound-guided stenting after failed ERCP improved the patient’s quality of life to the extent that there was no need for any external drainage.

Recent evidence indicates that water is one of the most overlooked and underestimated sources of healthcare-associated infections (HAIs). Opportunistic premise plumbing pathogens (OPPPs) are a group of natural waterborne pathogens that can persist in premise plumbing for long periods because of their unique characteristics. These include disinfectant resistance, viability inside amoeba, biofilm formation, and growth in nutrient-depleted environments. The pathogens can affect patients through various mechanisms, including direct contact, ingestion, aspiration, and aerosol inhalation. Most importantly, the transfer of pathogens between human microbiota and premise plumbing can cause hospital water systems to be reservoirs of multidrug-resistant bacteria. Biofilms formed on the outlet devices, such as tap faucets, shower heads, and sink drains provides an ideal niche for transmission of antimicrobial resistance. Contaminated wastewater systems are often sources of HAIs. A combination of interventions must be employed to manage water-related HAIs, including the general reinforcement of infection control measures, thermal and chemical disinfection, and consistent water flow.

In March 2020, the World Health Organization (WHO) declared coronavirus disease 2019 (COVID-19) a pandemic. Given the urgent need for vaccines against COVID-19, huge financial investments and global scientific collaborations have been made to develop effective and safe vaccines. To date, WHO has included five COVID-19 vaccines, comprising BNT162b2 (Pfizer-BioNTech), mRNA-1273 (Moderna), AZD1222 (AstraZeneca), Ad26.COV2.S (Johnson and Johnson’s Janssen), and BBIBP-CorV (Sinopharm) under WHO Emergency Use Listing as they are considered to meet the necessary criteria for safety and efficacy. In Korea, the Pfizer-BioNTech vaccine and AstraZeneca vaccine have been administered since February 2021, and three more COVID-19 vaccines are scheduled for incorporation till the end of 2021. This article focuses on the clinical and technical considerations of COVID-19 vaccinations to provide accurate and safe guidance for healthcare practitioners. A brief review of COVID-19 vaccines to be introduced in Korea is also summarized.

전기차 및 수소차 생산을 위한 거래 협력 네트워크의 공간적 변화

김영롱,김국동 경기연구원 2019 경기개발연구원 기본연구 Vol.- No.-

국가 기간산업이자 종합산업으로 한국 경제를 견인해 온 자동차 산업은 최근 큰 기술적 변화를 거치고 있다. 내연기관차에서 전기차 및 수소차로의 기술적 이행으로 인해 그에 필요한 수많은 자동차 부품이 변화함에 따라, 그 파급효과는 자동차 산업에만 국한되지 않을 것이다. 이러한 변화를 분석하기 위해서는 자동차 한 대가 완성되기까지 필요한 수많은 부품을 공급하는 기업들로 구성되는 자동차 산업의 거래 협력 네트워크 차원의 변화에 주목할 필요가 있다. 이 연구는 내연기관차에서 전기차 및 수소차로 기술적 이행이 일어남에 따라 나타나는 거래 협력 네트워크 상의 공간적 변화를 분석하는 것을 목적으로 한다. 먼저 자동차 및 그 관련 산업에 속하는 기업들의 주소 정보를 이용하여 국내 자동차 산업의 공간적 분포를 분석하였다. 그리고 복잡한 원하청 거래 관계를 기반으로 하는 자동차 산업을 효과적으로 분석하기 위해 기업 간 거래 데이터를 바탕으로 자동차 산업의 거래 협력 네트워크를 재구성하였다. 이를 대상으로 사회연결망분석(social network analysis)을 실시하여 내연기관차 생산을 위한 거래 협력 네트워크와 전기차 및 수소차와 관련된 거래 협력 네트워크의 공간적, 네트워크 위상적 차이를 비교하였다. 자동차 및 관련 산업 기업들은 수도권과 영남권에 집중되어 있으며, 광주, 군산, 전주 등 지역 거점에는 국지적으로 집중되어 있다. 이는 다른 제조업과 크게 다르지 않은 패턴으로 산업화 과정의 지역적 편중을 드러내고 있으나, 다만 수도권의 경우에는 경기 남부-충남 북부까지 연계되는 집적지가 가장 명확하게 드러나며, 거래 관계 기업들까지 포함했을 때 서울 및 경기도의 인근 도시까지도 지역 생태계를 확장할 수 있다. 그리고 주요 완성차 업체를 중심으로 한 협력업체들의 입지를 살펴보면, 완성차 공장 인근에 상당히 집적하여 분포하는 것을 통해 자동차 산업은 여전히 지리적 제약이 큰 산업임을 확인할 수 있다. 내연기관차 관련 부품 생산에 비해 전기차 및 수소차 관련 부품 생산 기업들은 수도권, 영남권, 광주 지역에만 더욱 두드러지게 밀집해 있다. 경기도 동부, 강원도, 전라북도의 경우 내연기관차에서 전기차 및 수소차로의 기술적 이행으로 인해 지역에 산업위기가 발생할 수 있음을 의미한다. 사회연결망분석을 통해 네트워크의 위상을 비교해 보면, 전기차 및 수소차 생산을 위한 거래 협력 네트워크는 내연기관차에 비해 중심성이 낮고, 트리 구조로 비교적 분산되어 있는 형태를 띤다. 이 연구는 자동차 산업의 기술적 이행으로 인해 나타나는 공간적 변화를 기업 간 네트워크를 통해 실증적으로 분석했다는 데에 의의가 있다. 반면에 전기차 및 수소차 생산 기업을 구분하는 보다 엄밀한 방법을 적용하고, 해외기업들과의 거래 데이터를 통해 보완할 필요가 있다. In the last few years, technological transitions from internal combustion engine vehicles (ICEVs) to electric and fuel cell vehicles (EVs and FCVs) have disrupted not only the industry but also the regional economies embedding the industry. However, an empirical investigation on the recent industrial and regional change from the transitions has not been addressed. In particular, it is urgent to analyze the change in the overall network for the production of cars and the inter-firm relationship in the network. The purpose of this research is to analyze the spatial change of the inter-firm transaction network as the technological transition from ICEVs to EVs and FCVs. For an empirical analysis in this paper, a social network analysis was chosen to investigate the automotive industry, one of the most complex industries with multi-level supply and demand chains. Network indicators such as degree centrality and eigenvector centrality derived from a social network analysis can show the topological and spatial positions of subcontractors. First, we reconstructed the production network using an inter-firm transaction database which covers the most firms in the automotive industry in South Korea, one of the leading economies in the global automotive industry. Second, the change in the production network as the industry transits from ICEVs to EVs and FCVs was investigated by social network analysis. The firms in the automotive industry are geographically agglomerated in the Seoul Metropolitan Area and Yeongnam (the Southeast) Region in South Korea. This regional pattern is not much distinguished from other industries that have thrived in the regions in the last decades. Firms in the Metropolitan cluster is specially agglomerated in the Southern Gyeonggi Area and the Northern Chungnam Area. If firms in other industrial sectors which have transaction relationship with the automotive firms are included, the regional ecosystem covers Seoul and other cities in Gyeonggi. A close look at the production network based on the five major assembly plants shows that the automotive industry is subject to its geographical boundary. If the production network of ICEVs and that of EVs and FCVs are compared, the latter has a stronger pattern of agglomeration in the Metropolitan Area, Yeongnam Region, and Gwangju. This suggests that other regions may fall into industrial decline as the technological transition to EVs and FCVs. Social network analysis on the two different networks shows that the network of EVs and FCVs is more dispersed in terms of degree centrality. The contribution of the research comes from the empirical analysis of the spatial change of the production network by the technological transition in the automotive industry. For future research, it would be better to update the research with a more systematic method to identify the firms for ICEVs, EVs, and FCVs and the inter-firm transaction data on a global scale.
