일본의 상하수도 사업은 국토교통성(하수도)과 후생노동성(상수도)으로 크게 양분되어 있으며, 환경성이 수질을 담당하는 체제로 이루어져 있다. 이는 수량과 수질을 분리하고 있는 우리나라와도 크게 다를 바가 없다. 그러나 중앙에서의 다원적인 분리와는 또 다른 차원으로 지방자치단체에서는 상하수도 통합이 급속도로 진행되고 있다. 이는 기후변화라는 지구적 환경의 변화와 더불어 해외 물산업에 대한 경쟁력이 밑바탕이 되면서 가속화되고 있다. 즉, 아시아의 신흥국을 중심으로 급격한 경제발전에 따른 인구가 증가하면서 정수장 및 하수처리장의 건설과 더불어 누수 및 도수(盜水) 문제가 현재화하면서 이에 대한 운영관리기술의 도입이 시급해졌기 때문이다. 이러한 과제를 해결할 수 있는 충분한 기술과 경험을 보유하고 있는 일본의 지방자치단체가 해외 물산업을 전제로 지자체 내의 상하수도 통합을 추진하고 있다. 본 연구는 이처럼 이원적으로 이루어지고 있는 일본 상하수도 업무의 법제도적 차이를 살펴보고, 특히 지자체를 중심으로 전개되고 있는 상하수도 통합과정의 동향과 의의를 풍중시((豊中市)토요나까시)의 사례를 중심으로 살펴보았다. 풍중시(豊中市)는 2008년 상하수도 통합을 천명하면서 기존의 운영방침에서 크게 탈각하는 정책을 취하게 되었고, 이 정책을 통하여 시의 지속가능한 발전 및 위기관리체제를 일신하고, 나아가 기후변화에의 대응력 강화에까지 그 범위를 확장하고 있다. 지자체의 상하수도 통합논의가 가속화되는 반면, 일본 중앙 정부에서는 아직 이렇다 할 움직임을 보이지는 않고 있다. 이는 부처간의 이견차이가 큰 부분인 만큼 쉽사리 제도적인 변경으로 움직이기는 어려울 것이다. 그러나 밑으로부터의 이러한 거대한 개혁움직임과 그 동인의 정당성을 확보해가고 있는 과정을 감안한다면 정부차원의 상하수도 통합이 완전히 부정되기도 어렵다. 상하수도 통합논의와 관련한 일본의 사례는 향후 우리나라 상하수도 정책을 재검토할 수 있는 계기가 될 것이다.

Recently, the domestic department store industry is growing into a complex shopping cultural space, which is advanced and differentiated by changes in consumption patterns. In addition, competition is intensifying across 70 places operated by five large companies. This study investigates the determinants of the visits to department stores using the big data concept's automatic vehicle access system (pos) and proposes how to strengthen the competitiveness of the department store industry. We use a negative binomial regression test to predict the frequency of visits to 67 branches, except for three branches whose annual sales were incomplete due to the new opening in 2021. The results show that the demand for visiting department stores is positively associated with airport, terminal, and train stations, land areas, parking lots, VIP lounge numbers, luxury store ratio, F&B store numbers, non-commercial areas, and hotels. We suggest four strategies to enhance the competitiveness of domestic department stores. First, department store consumers have a high preference for luxury brands. Therefore, department stores need to form their own overseas buyer teams to discover and attract new luxury brands and attract customers who have a high demand for luxury brands. In addition, to attract consumers with high purchasing power and loyalty, it is necessary to provide more differentiated products and services for VIP customers than before. Second, it is desirable to focus on transportation hub areas such as train stations, airports, and terminals in Gyeonggi and Incheon. Third, department stores should attract tenants who can satisfy customers, given that key tenants are an important component of advanced shopping centers for department stores. Finally, the department store, a top-end shopping center, should be developed as a space with differentiated shopping, culture, dining out, and leisure services, such as "The Hyundai", which opened in 2021, to ensure future growth potential.

This paper is to provide information for quantitative evaluation of suspension bridge engineering and construction technology, technology development, and long-span bridge R&D agenda. Technology classification structure and key words are established and survey to identify technology level is performed. Then, competitiveness of patents and journal articles is evaluated for Korea, USA, Japan, Germany, France, and England. As a result, USA and Japan are generally competitive countries for all technology categories based on patents and journal articles. Korea is grouped in upper-middle class for overall technology level of suspension bridge. However, there are some variances among the level of technologies. This research results could be utilized as reference to establish future long-span bridge R&D. Also, it can be a standardized methodology to compare technology levels among countries.

R&D businesses lead by a government of each countries are recognized as important businesses that may affect the destinies of the nation. However, the process of developing a new business has not been so favorable as the process was primarily managed by engineers who concentrate on research development. The problem was solved by applying a business model regarding outcomes of a developed research. Yet it is difficult to apply the business model methods that are commonly used for enterprises to government's research businesses due to their unique research development characteristics. Therefore, it is developed a business model methodology for national R&D project in this study. In addition, the methodology applies to a sub-project of Korean Land Spatialization Program(KLSP) organized by Ministry of Land, Transport and Maritime Affairs to verify the possibility of practical application.

As the excessive competition between container terminals has been deepening, not only productivity, but also cost economic of the terminals has been raised. With regard to this, the competitiveness of the terminals is limited because of inefficiency operation of transfer crane(T/C) which needs large amount of energy consumption. Therefore, it is possible that the improvement in the T/C operation leads to saving cost for resources and energy as well as increasing the productivity of the terminals. This study provides 'the K-Means Clustering based Optimized Decision Model for Transfer Crane Operation', referring to 'RFID & RTLS based Port Logistics Initiative' of Ministry of Land, Transportation and Maritime Affairs and estimates the efficiency through simulating.

This urban centralization is expected to develop rapidly, with 75% of the population living in the city by 2035. Large cities are becoming unsustainable due to side effects such as environmental pollution, severe traffic jams, excessive energy depletion, and destruction of the natural ecosystem. In addition, the happiness index of citizens of large cities is also falling because of high crime rates and safety accidents, the work-life imbalance caused by inequality and polarization, and overly competitive education. To solve this problem, Smart City, an IT-based future city model, was born. The Korean government is also actively attempting to improve urban competitiveness and promote sustainable development through efficient construction and operation of smart cities as a national focus project. To support the effort, we review the basic directions and strategies of Sejong City's Smart City service infrastructure based on the comprehensive national land plan, Smart City plan, and Smart City strategy plan.

R&D projects for land, infrastructure, and transportation is to identify challenges through academic-industrial demand survey, and to promote R&D projects through detailed planning projects. These R&D projects have been promoted to be applied to most domestic project-oriented. Despite continuous R&D investment, the investment has been promoted to the world top technology rather than to international construction projects. This study analyzed the international construction market trends and international construction contracts in order to promote technology development for enhancing international construction competitiveness. This study suggests three R&D technology development directions and ten research projects for expanding international construction projects.

Since 2008 the administration of the President Lee Myung-bak is pursuing a new regional policy which differentiates from that of the last administration. It focuses on the maximizing the growth potential of the national territory and suggests the three-tiered regional development system. The paper aims to review the main contents and characteristics of the macro-economic region policy as a representative strategy in a new regional development policy and examine its achievements and the future tasks. Although it is limited to evaluate the accomplishments of the macro-economic region policy due to the short period of time (3 years), it has been successfully recognized that it would be more competitive if regional governments are supporting and connecting each other with neighboring regional governments. In addition, investments to each macro-economic region continue vigorously as planned. In order for the policy to be more successful in the future, however, it is necessary to substantially expand the development project, to systematically construct the governance structure, and to effectively process the industrial plans.
