Recently, international society strongly concerns global green house effect. As a result each nation introduces green policy for their economy and sustainable development. The emissions of carbon dioxide come from various sources, such as ports and port activities. Especially, port is a logistics hub for shipping, road and railways. Therefore, successful reduction of emissions in the port may encourage other transportations to reduce emissions. Korea as developing country is excused from Annex I countries which committed themselves to reduce four greenhouse gases. However, Korea is going to be placed in Annex I countries in 2013. Korean economy is heavily dependent on international trade and especially, 99.8% of its international trade cargoes is transported through the ports. Therefore, Eco-port plays a very important role in future Korean sustainable development. By introducing the most advanced port pollution regulations, Japan has taken a immediate step for Eco-port policy. International trade is very significant in Korea as well as in Japan, both nations have similar industrial structure. Therefore, Korea should pay attention to Japanese Eco-port policy and activities. This paper examines Japanese Eco-port policy and its' implications in order for Korea to find the most efficient way to reduce the emissions as Korea should reduce greenhouse gas emissions in post kyoto system.

The purpose of this study is to review the changes in the aviation safety management system, how that system has evolved and what forces caused these changes to take place. Also included is an examination of the development process of the aviation safety management system in view of the new institutionalism, identifying the patterns of change. Based on the results of this study, I propose policy methods to design a desirable civil aviation safety system with a view toward raising the safety standards in the Korean civil aviation community. The major analysis variables are as follows: first, aviation accidents caused by external factors and international standards as independent variables second, environmental changes and political processes affecting aviation safety management system as major mediating variables and third, the aviation safety management legal system, the aviation safety management organizations and an expert participation system as dependent variables. The institutional changes and continuance of the aviation safety management system show that when specific circumstances arise, the continuance lasts depending on the path dependency, and in a certain circumstance, when immanent changing factors reach a critical point, the system suddenly changes by a punctuated equilibrium, which are all included in this study.

Since China opened its door to the world in 1978, its economic development had been concentrated in the Eastern and Western area compared with the middle area. From 2000s, the Chinese government started to develop the middle area in terms of balanced development. With this goal, "Plan on Zhengzhou Airport Economy Zone", and "One Belt and One Road" has implemented in Zhengzhou, where is the an important traffic center in middle area. Meanwhile, the foreign trade of Zhengzhou has been increased about 10 times between 2009 and 2018. In particular, its growth is the fastest among six central cities in 2018 from the lowest in 2009. This study investigates whether the Chinese government policy has an effect on the foreign trade of Zhengzhou. We find that based on the regression analysis of the Principal Component Analysis (PCA), the government policies has a positive impact on the development of Zhengzhou's foreign trade. It is meaningful that the government policy focused on the advantage of Zhengzhou contributes its development of foreign trade.

본고는 다음과 같은 문제를 제기한다. 해외직접투자와 관련한 우려 중의 하나가 수출이 잘되고 있는 부문에서 해외투자가 증가하여 국내의 수출기반을 약화시킬 수 있다는 것인데, 이를 어떻게 해석할 수 있을 것인가? 이 문제에 대한 접근을 위해 본 논문에서는 우리나라 수출입(輸出入) 및 해외직접투자(海外直接投資)의 구조변화(構造變化)에 관한 분석을 시도하고 해외직접투자의 요인(要因)을 추론하였다. 근년에 해외직접투자가 급증하면서 해외직접투자의 경제적 효과에 대한 관심이 높아지고 산업공동화를 우려하는 견해도 대두되고 있다. 특히 우리 기업의 해외진출을 진출(進出)이 아닌 탈출(脫出)로 인식하기도 한다. 고임금, 고금리, 고지가, 고물류비 등 국내의 고비용 구조가 우리 기업을 해외로 몰아내고 있다는 것이다. 본고는 해외투자에 관한 이러한 시각이 우리 기업의 해외투자가 기업고유(企業固有)의 자산(資産) 또는 경쟁우위(競爭優位)를 활용 강화하기 위해 이루어지는 측면을 간과하고 있음을 지적한다. 본고는 다음과 같은 점을 강조한다. 우선 해외투자는 경쟁우위가 증가하는 부문(본고에서는 수출비중이 커지는 부문)에서 오히려 더 자주 이루어지는 경향이 있다는 것이다. 이는 절충적 패러다임에서의 소유권우위적 요소가 해외투자의 요인 및 양상을 설명하는 데 중요함을 의미한다. 우리나라의 최대 수출업종인 조립금속 기계장비부문에서의 해외투자 증가도 이러한 맥락에서 보면 아주 당연하다고 할 수 있다. 그리고 조립금속 기계장비부문의 해외투자 내용을 살펴보면 주로 보급률이 높은 중저급 성숙기제품 중심으로 해외투자가 이루어지고 고급제품은 주로 국내에서 생산되거나 선진기술습득을 위해 선진국에서 생산되고 있는 것으로 판단된다. 결과적으로 주요수출업종(主要輸出業種)에서의 해외투자(海外投資)는 오히려 당연하고 내용면에서도 국내경제(國內經濟)의 구조고도화(構造高度化)를 저해하지는 않는 것으로 판단된다. 본고는 향후 정책이 해외직접투자가 국내산업구조(國內産業構造)의 질적(質的) 고도화(高度化)에 효과적(效果的)으로 기여하는 방향으로 마련되어야 함을 강조하고 이를 위해 국내(國內) 기술기반(技術基盤)의 강화(强化), 고급인력(高級人力) 개발(開發) 등을 제안한다. 해외직접투자의 증가가 국내 고부가 직종의 증가로 이어지고 이것이 저부가 직종의 감소를 상회하도록 해야 하고, 이러한 정책이 실패하면 국내의 고용감소는 불가피하며 고용감소를 우려하여 해외직접투자를 인위적으로 규제하는 것은 고용사정을 더욱 악화시킬 뿐임을 강조한다.

Planning railferry system in Korea-China trade routes, the overall evaluation and customer response are coming under spotlight in a preference and feasibility perspective. Persistent Railferry issue has been an area of study for the last decade. But until now, a surveyor or the evaluation from the actual users were exceptionally rate. Consequently, there is a need for a more detailed study into the practical issues such as customer response and railferry demand etc. Using a questionnaire survey from actual users, this paper examines the underlying evaluation on the Railferry system both in terms of demand and preference. The research questions were analyzed on data collected from almost 150 users in Korea. A range of arguments and expected problems were summarized. The results in general find a negative relationship between railferry preference and respondents' work experience. Findings in the reasons respondents are objecting the new railferry system, the suitable cargo type of railferry, and the possible barriers to introduce the system are discussed. Nonetheless further researches into railferry system as a possible alternative for Korea-China-Japan corridor should be followed in the near future.

The major factors that threaten port operation are diversie. Coronavirus disease-19, (COVID-19), which has recently disrupted operations worldwide, is one of them. Port operation was completely stopped due to a confirmed coronavirus involving a Russian sailor in Gamcheon Port, Busan, Korea in 2020, resulting port closure due to the infectious disease outbreak. The port is a national infrastructure facility that controls most of Korea's import and export logistics, and it is absolutely necessary to secure resilience against threats such as infectious diseases. However, due to insufficient data, this study was undertaken to determine a cause-effect relationship of infectious diseases during the container port operation using system dynamics. In addition, the port's resilience against infectious diseases was measured in terms of productivity and cargo volume through simulation. The model built via simulation analysis can actually be used to measure the resilience of a port. In the event of an infectious disease outbreak at a port, a quarantine policy scenario can be implemented and the effect compared, thereby improving the resilience.

The purpose of this study is to analyze bibliographic information of Busan and other cities' reports for urban development initiative and identify the strategic fields for future smart city plan. Text mining method is used in this study to extract keywords and identify the characteristics and patterns of information in urban development reports. As a result, in earlier stage, Busan city focused on service creation for industrial development but there are lack of discussions on the linkage of information systems with ICT technology. However, recent urban planning in Busan contained various contents related to integrated connections of infrastructure, ICT system, and operation management of city in the specific fields of traffic, tourism, welfare, port/logistics, culture/MICE. This results of study is expected to provide policy implications for planning the future urban initiatives of smart city development.

This review article summarizes the trends and issues around the mobility business and government regulations in Korea. Key issues identified involve unclear government regulations, conflict management between key stakeholders, platform labor, and regional conflicts. The study then offers an overview of the current government regulations on the mobility business and conflict management, along with some policy recommendations in the areas of linking conflict resolution efforts with the welfare safety net, and corporates' social responsibility for the sustainable ecosystem. Ultimately, an ecosystem is required for multiple ministries and stakeholders to participate in the process of improving the regulations, as well as a control tower (government agency) who plays the pivotal role as a coordinator.

The purpose of this study is to find a reasonable solution that is compatible with the government's policy on calming the overheated housing market and the needs of prospective home buyers. For this purpose, this study analyzed the current state of the housing market and looked at the root cause of the people's desire to purchase housing. And this study suggested the need to introduce a super-long-term mortgage system that can help people choose whether to own or rent a house in accordance with individual preferences. The super-long-term mortgage system would be useful in that the majority of people who currently use mortgages prefer long-term loan products and that it could provide a chance to "get their own homes" by easing the monthly repayment burden for those who want to have homes. If the system is introduced in the future, it is necessary to make efforts for stable operation such as risk-hedge. In particular, the government should apply a limited application to end-users so that they can curb rising housing prices and contribute to stabilizing housing prices.

Despite the recent economic contraction caused by the Corona 19 incident, interest in the residential environment is growing as more people live at home due to the increase in telecommuting, thereby increasing demand for remodeling. In addition, the government's real estate policy is also expected to have a visible impact on the sales of the interior and furniture industries as it shifts from regulatory policy to the expansion of housing supply. Accurate demand forecasting is a problem directly related to inventory management, and a good demand forecast can reduce logistics and inventory costs due to overproduction by eliminating the need to have unnecessary inventory. However, it is a difficult problem to predict accurate demand because external factors such as constantly changing economic trends, market trends, and social issues must be taken into account. In this study, LSTM model and 1D-CNN model were compared and analyzed by artificial intelligence-based time series analysis method to produce reliable results for manufacturers producing furniture components.
