As the size of container ships continues to increase, not many existing harbors can host the super-container ship due to its increased draft and the corresponding dredging requires huge budget. In addition, the minimization of waiting and loading/offloading time is the most important factor in harbor competitiveness. In this regard, mobile-harbor concept has been developed in Korea to achieve much improved harbor capacity and efficiency. In developing the concept, one of the most important elements is the operability of crane between two or more floating bodies in side-by-side arrangement. The container ship is to be stationed through a hawser connection to an outside-harbor fixed-pile station with the depth allowing its large draft. The mobile harbors with smart cranes are berthed to the sides of its hull for loading/offloading containers and transportation. For successful operation, the relative motions between the two or more floating bodies with hawser/fender connections have to be within allowable range. Therefore, the reliable prediction of the relative motions of the multiple floating bodies with realistic mooring system is essential to find the best hull particulars, hawser/mooring/fender arrangement, and crane/docking-station design. Time-domain multi-hull-mooring coupled dynamic analysis program is used to assess the hydrodynamic interactions among the multiple floating bodies and the global performance of the system. Both collinear and non-collinear wind-wave-current environments are applied to the system. It is found that the non-collinear case can equally be functional in dynamics view compared to the collinear case but undesirable phenomena associated with vessel responses and hawser tensions can also happen at certain conditions, so more care needs to be taken.
The aim of this project is to develop an adaptive and collective National Marine Biotechnology Plan for the next decade(2014~2023) which is able to reflect current and future changing environment. This effective strategy targets to foster marine-derived active bio-materials, marine bioenergy production technology and many promising technologies in order to promote marine biotechnology industry as a next-generation growth engine. Marine biotechnology industry based on R&D activities since 1980 has been growing as an emerging industry. This new field enables to secure exclusive patent rights and to find new potential bio-active materials from the ocean that requires long-term aggressive R&D investments. The current policy direction is to raise appropriate level of R&D investment because the current Korea's national marine biotechnology R&D fund ratio is less than 2% of the total national biotechnology R&D budget. The result shows three major strategies. First, it recommended a research implementation system and supporting policy that includes establishment of open innovation framework for the 'Industry-Academia-Research Institute Collaborations', strategic research planning and enhanced policy making process. Second, it derived state-of-the-art or new technology in many areas. Third, it formulated more detailed execution plans for successful R&D support and set up performance indicator system in related R&D program.
Purpose: Previous studies have highlighted that the nutritional behaviors among South Korean workers are far from ideal. This study examined the organizational influences affecting the eating practices of office workers in South Korea. Methods: We conducted in-depth interviews with 22 office workers at 12 companies in South Korea. The interviewer inquired about the employees' daily routines on food and beverage intake. The various factors that influence their food choices in their work environments were also explored. The interviews were transcribed and then analyzed using a content analysis. Results: A framework analysis revealed 7 key recurring themes, and these were grouped under three levels: team-, company-, and corporate group-levels. First, team dinners are core social events for all the workers and they tend to include high-caloric food and alcoholic beverages. The frequency of team meals and the food associated with them depend on various team characteristics such as gender composition, the nature of a team's work and the team leaders' emphasis on group meals. Second, the company's policies and practices regarding budget allocation for team meals and subsidies for cafeteria meals affect the workers' food intake practices. In addition, the physical environment of the worksite cafeterias can influence the choices of foods. Third, various corporate group policies that were not designed to target food intake had additional positive effects on the workers' eating behaviors. Conclusion: This study provides important insights into the broader organizational influences on the food consumption of employees in their workplace. These insights can be used to design and implement more effective intervention strategies for improving the nutritional behaviors of office workers.

Recently, companies and organizations are becoming increasingly dependent on external resources to keep their competitive advantages under the turbulence of global business environmental changes. Therefore, they focus on the paradigm 'Open Innovation (OI)' which is reported as a convincing strategy to improve competitive advantage in terms of budget and time-to-market. The management of Incheon International Airport Corporation (IIAC) also considers the introduction of Open Innovation not only to adapt the business environmental changes but also to be devoted its social role as a public corporation. In this paper, we describe how we derived the promotion tasks for the introduction of OI and prioritized the tasks, performing our research on the IIAC Open Innovation. For these purposes, this research conducted the following three steps; the first stage for the analysis of current situation on the IIAC Open Innovation, the second stage for the elicitation of promotion tasks, and the last stage for the prioritization of the promotion tasks. In the first stage, critical success factors (CSFs) for open innovation introduction were derived from different research papers and case studies. In the following stage, promotion tasks were elicited from the IIAC based on the CSFs. In the last stage, the promotion tasks were evaluated on the base of criteria by using Analytic Hierarchy Process (AHP). And then the promotion tasks were grouped by the result of the evaluation. In this case, thirteen promotion tasks were derived for open innovation, ten promotion tasks except three inevitable promotion tasks were evaluated, and then they were grouped into four categories based on the importance-possibility analysis.
This study aimed to examine how the horticultural therapy that was originated in the US has influenced South Korea and Japan and developed in the two countries as an interim check to promote qualitative growth of horticultural therapy with the growing social attention. It also aimed to look into the background of how horticultural therapy was introduced in Japan (which introduced horticultural therapy around the same time as Korea), and the process of the introduction, and compare them with those of Korea in order to set the direction for horticultural therapy. Data was collected to prepare the chronological table of horticultural therapy in Korea and Japan and investigate the flow. Interviews were conducted with the professors who first opened a horticultural therapy course in university so as to determine the introduction background. The analysis results are summarized as follows: Horticultural therapy was created to give mental comfort and emotional purification to those concerned with horticulture that had concerns over social phenomena. In Korea, there had been a process of finding a way of getting mental comfort and emotional purification in the economic slowdown in the late 1990s. Since 2001, there have been more attention and demand for horticultural therapy. As a result, there has been a tendency of studying general horticultural welfare activities and professional horticultural therapy separately. In Japan, the environmental pollution that has arisen since 1970s led to a concern over social orientation in the relation between plants and humans. The academic conference of global researchers to establish the horticultural therapy studies influenced the introduction of horticultural therapy in Korea and Japan. Both countries had no operations and system, and developed them independently. They had similar directions to seek, such as the department of horticultural therapy, need for professional education, active introduction of hospital practice (internship), and security of operating budget. Horticultural therapy has many competencies and thus requires constant research and expansion.

Today, in the information society, since the government administration of all countries places importance on clarity and efficiency, the authority concentration of the administration is inevitable. Therefore, the Parliament, which is a legislative body, is at a time when the policy control function to check and monitor it is becoming more important. In particular, due to the emergence of parliamentary democracy, in the reality that the people must elect representatives and represent their own opinions, the parliamentary inspection system is very valuable in that it satisfies the right of the people to know and ultimately enables the people to democratically control the administration. The role of the Parliament moves from the inherent legislative function to the information collection and disclosure of government administration, discussion and resolution of political issues, and observation and supervision of the administration. And it can be seen as the global trend. As a result of this trend, status and role of the National Assembly is being strengthened from the legislative body to the control agency of government administration. Thus, the most substantive authority of Article 61 of the Constitution can be deemed the parliamentary inspection system. The parliamentary inspection system is a system that let exercise the legislation, budget, and authority to control of state administration by identify the challenges and policy implementation of each country's institutions through the audit of the executive administration's overall government administration performance outside the National Assembly. However, due to the amendment of Constitution in 1988, the parliamentary inspection right and investigation of state administration right had reinstated and the parliamentary inspection system, which is being implemented annually, is the 31st year of the year in 2019. However, the general evaluation of the public is negative and insufficient time for inspections, lack of sanctions on nonattendance witnesses, excessive data submission, and refusal to submit materials by the administration were pointed out as the problem. Therefore, in this paper, the researcher tries to point out the overall problems of the parliamentary inspection system and to summarize the effective improvement plans.

In government procurement programs, cost estimation and analysis support funding decisions and are the basis for other major decisions, too. Such estimating and analyzing the cost of the weapon systems are crucial in execution of the defense budget. However, existing cost estimations and analyses have focused on domestic R&D projects, thus those are not valid in application to foreign weapon acquisitions. This study aims at foreign weapon systems that are acquired from Direct Commercial Sales. Because the data for price estimation of a foreign weapon is usually not available, we suggest a price estimation model based on performance factors of the weapon. In this study, the proper price of the weapon system is estimated using the parametric cost estimating model. Using the data of helicopter-launched anti-tank guided missiles worldwide, we analyze the effect of each performance factor on the weapon system price by regression analysis, and use step-wise and ridge regression analysis to remove multi-collinearity. This study hopefully contributes to more reasonable decision making on proper price of weapons.

PURPOSE: Focusing on the factors that influence the infectious disease emergency response policy (approached by dividing the factors into health policy management and economic policies), both SARS and MERS cases were based on the legal system, manpower, and budget, but there has not been enough learning from the epidemic. This study focused on infectious disease emergency governance, which various studies have neglected despite its social and academic importance. METHODS: The research is based on an analysis of SARS, MERS, and COVID-19 and compares global policies. In this study, infectious disease emergency governance was divided into health policy management and economic factors. This study focused on planning and leadership before and after the outbreak of infectious diseases and how cooperation was achieved to monitor and respond to infectious diseases successfully. RESULTS and CONCLUSION: The limit of this study was that COVID-19 is a currently ongoing infectious disease with high uncertainty. Because it is an ongoing problem, only some data and statistics are reflected, and many limitations prevent a proper comparison under the same criteria as other infectious diseases. In addition, because continuous changes are expected, there is also room for infectious diseases to develop in a completely different pattern from the current situation, and continuous research must be accompanied in the future.

Establishing an investment evaluation system for public ICT projects is ultimately to increase the success rate of public ICT projects in which government finances are invested and to revitalize the projects, thereby establishing a foundation for national economic growth and enhancing the competitiveness of the global ICT industry. This study tried to empirically verify the effect of public ICT project investment evaluation factors established according to the existing evaluation system on actual project success, and to suggest directions for future investment evaluation factors. Five evaluation factors such as public interest, economic feasibility, technology, policy and budget efficiency were derived through prior research, and the effect of these evaluation criteria on actual project success was verified through questionnaires from experts who directly participated in the actual project. In addition, it was confirmed whether the government's support system had a moderating effect between the investment evaluation factors and the project success of the ICT project. The reliability and validity of measurement tools, structural model analysis, and path analysis were empirically analyzed, and the significance of existing ICT investment evaluation factors was verified.
In order to confirm the effects of economic growth and environmental improvement, this study analyzed the existence of environmental Kuznets curve (EKC) for SO2 emission, greenhouse gas emission, and waste generation in OECD countries. As a result of panel analysis, the shape of the EKC were different depending on environmental pollutants. SO2 generated peaks relatively early in economic growth, and the peak of greenhouse gas emissions was showed in higher income level. But both emissions showed the a complete inverted U-shaped curve decreasing after the peak. On the other hand, for waste, there was no environmental Kuznets curve that could confirm the peak. Therefore, this study confirmed that it is difficult to expect a voluntary reduction in all environmental pollutants, and additional global joint efforts are needed to pass the peak. In particular, since waste has a greater impact on population density and industrial structure than income level, additional policy efforts are needed to reduce generation and create a resource circulation system.
