Since the designation of the South Korean Construction industry as an open market industry by the World Trade Organization (WTO) in 1994, South Korea's construction firms were exposed to competition from firms of other advanced countries. Increased competition in the industry raised quality of production and lowered the cost of construction projects. Therefore, many big construction projects were planned and constructed with foreign construction partners during the last decade. Also, from those projects the South Korea Construction industry accumulated experience in and knowledge of both project management and construction management perspectives. However, in the process of conducting those big projects, many problems - specifically responsibility and the limit of competence - occurred between foreign construction partners. Hence, this study attempts to improve its role model that is for local and foreign companies to enter into Joint Ventures in the South Korea construction industry.

Purpose - The purpose of this study is to examine how a broad palette of government support measures and firms' membership in government-developed clusters are related to firms' openness in innovation processes. Design/methodology/approach - Empirically, this study analyzes the Korea Innovation Survey 2018 data on the innovation activities of 1,450 Korean R&D-active manufacturing firms in a three-year period from 2015 through 2017. Findings - The results suggest that firms engage in open innovation to a greater extent--as measured by the breadth of external collaborating partners and of the utilized external sources of knowledge--when they are provided with a broader palette of government support measures and are located in government-developed clusters. However, the effect of diverse government support measures is attenuated for firms located in these clusters. Research implications or Originality - This study contributes to the innovation literature by illuminating how firms' open innovation can be understood in a national innovation system. Moreover, it provides valuable implications for firms seeking to obtain government support and collaborate with others.

China has emerged as the world's factory since the economic reform in 1987, and the Chinese economy has been growing at a rapid pace. Now, China is considered as one of the biggest markets in the world. Thus, many Korean IT service companies including open market operators have interests in expanding their business into China. However, to be successful in Chinese online shopping market, Korean open market operators should check the cultural differences between the online shoppers in Korea and China at first, Under this background, this study proposes the factors affecting user satisfaction in open market services based on the revised Delone and McLean model. Then, it investigates the differences in the effects of these factors across Korea and China. For empirical analysis, we collected the survey data from open market users in both countries, and applied multiple regression analysis to the data. As a result, we found significant differences between Korean and Chinese open market users. Also, we found that most of these differences could be explained using Hofstede's Cultural Dimensions theory. The findings of this paper imply that Korean and Chinese users may respond differently to IT services, though Korea and China are geographically close and share a similar cultural background.

The foreign concession of Yokohama was the first downtown formed through the open port of Yokohama. It became a stepping stone to the center of the market economy. Yokohama was regarded as the turning point of modernization in Japanese history and it reached the high light of modern city in Japan. In the nineteenth century the term "open port" which occurred in East Asia was directly connected with modernization. Nevertheless, there is not many researches on architectural history about the central space of the open port city. As the method of research, we examine the parcels and spatial changes that are based on the contents of maps and pictures in terms of architectural history. For the foreign concession that was set up in Yokohama and the first open port in Japan, the spatial scope was set for certain and the temporal range was also set from the setting of the concession in 1859 to the abolition in 1899. The purpose of this study is to consider the future research related to the study of the open port city from the perspective of comparative historical research.

This study examined the impact of changes in agricultural production methods on society, the economy, and the environment. While traditional open-field farming relied heavily on natural conditions, modern approaches, including greenhouse and smart farming, have emerged to mitigate the effects of climate and seasonal variations. Facility horticulture has been on the rise since the 1990s, and recently, there has been a growing interest in smart farms due to reasons such as climate change adaptation and food security. We compared open-field spinach and greenhouse spinach using agricultural income survey data, and we also compared greenhouse tomato cultivation with smart farming tomato cultivation, utilizing data from the smart farm survey reports. The economic results showed that greenhouse spinach increased yield by 25.8% but experienced a 29% decrease in income due to equipment depreciation. In the case of tomato production in smart farms, both yield and income increased by 36-39% and 34-46%, respectively. In terms of environmental impact, we also compared fertilizer and energy usage. It was found that greenhouse spinach used 29% less fertilizer but 14% more energy compared to open-field spinach. Smart farming for tomatoes saw a negligible decrease in electricity and fuel costs. Regarding the social impact, greenhouse spinach reduced labor hours by 31%, and the introduction of smart farming for tomatoes led to an average 11% reduction in labor hours. This reduction is expected to have a positive effect on sustainable farming. In conclusion, the transition from open-field to greenhouse cultivation and from greenhouse cultivation to smart farming appears to yield positive effects on the economy, environment, and society. Particularly, the reduction in labor hours is beneficial and could potentially contribute to an increase in rural populations.

The works of the special economic zone for regional development(SEZone) have been promoted for developing the regional economy corresponding with its own peculiarities by not national, but local level of government. Namely, those set the goal at specialized development of regions through an appeasement policy against regulations. So local governments. must originate the local works, get financial sources by itself, and then revitalize the regional economy. The policies of many local governments aim at increasing farmers' income by developing rural society to cope with open economy system. By the way they have tried to revitalize agriculture and rural society by promoting actively the works of SEZone through an appeasement policy against regulations. And it is important to search for specialized factors based on regional resources, and to make connected with them together so as to obtain good results in the works of SEZone. This study examined regulations related to environmentally friendly agriculture and green tourism. And it researched about the effect of SEZone works on regional economy and develops indices of result estimation. So schemes for strategies for increasing demand and development issues were presented.

This study analyzes the historical events that shaped South Korean Foreign Direct Investment (FDI) and its value to businesspeople. Chapter 2 reviews South Korean FDI literature, highlighting critical studies and a research gap. Chapter 3 strategically separates findings into four major historical events. Every event-from economic liberalization to technical advances-is studied. Chapter 5 offers valuable insights and guidance on how these events affect practitioners. The following chapters aim to promote FDI dynamics understanding and enable businesses and governments to make strategic decisions in South Korea's dynamic economy. Foreign Direct Investment (FDI) history in Korea is significant for practitioners. These events have impacted the nation's economy from the 1960s economic liberalization to modern technology advances. Practitioners must understand these events' far-reaching implications to make informed decisions. The opening up of the economy, chaebols' involvement, financial crises, and high-tech industry emphasis provide excellent lessons. This understanding helps practitioners navigate the global economy, adapt, and be resilient for sustainable economic growth in the Republic of Korea. Thus, practitioners should actively advocate for FDI and economic growth policies with government agencies. Collaboration ensures that the government's strategic vision matches industry practitioners' requirements and goals. By working together, practitioners help create policies that make Korea more appealing to international investors.

Existing grade crossings between railway and roadway area gradually changed to grade separation systems by the law. In the case of new roadway construction which crosses railways, it shall be grade separation system in principle. With the railway underground crossing method, many practices have been developed which can minimize rail displacements and avoid rail release. With these methods, the effects to the train can be reduced. The underground crossing methods can be identified as open-cut methods and non open-cut methods. The open-cut methods include temporary support methods and special rail construction methods. Also the non open-cut methods includes pipe roof methods, front jacking methods, messer shield methods, NTR methods and JES methods. Among these, the most suitable method is applied considering safety, economy, class of each rail system (train passing frequency and velocity), etc. In the non open-cut methods, the cost and duration shall be increased to keep existing rail system during construction. In the open-cut methods which use plate girders, the rail speed shall be restricted due to the displacement and vibration of the girder. In this study new grade separation methods were developed. With this method, the safety during construction can be increased. This method refines temporary support methods, but pc slab girder with huge stiffness is applied instead of plate girders. With this method, the rail displacement can be reduced and higher safety can be obtained during construction. Also construction cost and duration can be minimized because the temporary work and the overburden soil depth can be reduced.
