In this paper, Human-in-the-Loop (HiTL) simulations of Remotely Piloted Aircraft System (RPAS) operations in two different Air Traffic Management (ATM) concepts, conventional radar vectoring and Trajectory Based Operations (TBO), were performed to assess the impacts of RPAS integration in the future ATM environment. TBO concept maximizes the throughput by planning and sharing 4-D trajectories between pilots and controllers, and it is considered one of the key concepts to enable RPASs to operate with manned aircraft in congested airspaces. RPASs are characterized by having communication delay or temporary loss of communication. TBO capability was added to the integrated air traffic simulation system for this study, which was developed in the Inha University. HiTL simulations were performed by a trainee air traffic controller with three scenarios, and the data were analyzed using safety, efficiency, and controller workload metrics. The results suggest that TBO were effective in reducing delays and controller workload while maintaining the level of safety.

The paper deals with three main topics: a) the definition of System Thermal-Hydraulics (SYS TH), b) a historical outline for SYS TH and, c) the description of elements for reflection when planning research projects or improvement activities, this last topic being the main reason for the paper. Distinctions between basic thermal-hydraulics and computational Fluid-Dynamics (CFD) on the one side and SYS TH on the other side are considered under the first topic; stakeholders in the technology are identified. The proposal of Interim Acceptance Criteria for Emergency Core Cooling Systems in 1971 by US NRC (AEC at the time) is recognized as the starting date or the triggering event for SYS TH (second topic). The complex codes and the main experimental programs (list provided in the paper) constitute the pillars for SYS TH. Caution or warning statements are introduced in advance when discussing the third topic: a single person (or a researcher) has little to no possibility, or capability, of streamlining the forthcoming investments or to propose a roadmap for future activities. Nevertheless, the ambitious attempt to foresee developments in this area has been pursued without constraints connected with the availability of funds and with industrial benefits or interests. Demonstrating the acceptability of current SYS TH limitations and training in the application of those codes are mentioned as the main challenges for forthcoming research activities.

There may exist differences in R&D patterns between multinational enterprises and domestically owned firms located in catching-up countries. This paper examines the differences in R&D patterns between different ownership in Korea. In order to do this, the paper has conducted the in-depth interview of the major multinational and local firms. The interviewed firms has been selected mainly from the telecommunication, semiconductor and display industries. The paper reveals that multinational firms tend to focus on sales-oriented R& while domestically owned firms are likely to cover the range of development, applied and basic research. The most outstanding difference lies in the length of R&D period. The domestic firms apparently turn out to conduct longer period R&D projects than multinational firms. In addition it is revealed that local firms need to develop their own capability, whereas foreign companies in Korea can acquire advanced technology and scientific knowledge from the R&D centers in their home countries. On the basis of the research findings, this paper discusses some implications and recommendations for Korea and other catching-up countries.

This paper illustrates key features of an enterprise employment simulation which integrates a system dynamic feedback model with a cost-effectiveness optimisation capability utilising genetic algorithms. Its core is a 3-dimensional array structure tracking staff numbers by rank, by time-in-rank, by years-of-service. The resultant model, which could readily be adapted to non-Defence use, can identify, given user specification of any mix of employment rules, the likely patterns of employment behaviour including: resultant time-in-rank and years-of-service profiles; ability of a Unit to fill all positions to target strength; ability to fill promotional positions within normal rules for substantive promotion; need to fill promotional positions using rules for temporary promotion or transfer from outside; necessary recruitment pattern to sustain target strength.

The previous studies found the importance of market orientation (MO), learning orientation (LO), and marketing capabilities (MC) in driving firm performance (FP), but respectively. This research attempted to integrate the rather separate research streams of MO, LO, and MC in explaining FP. How MO and LO, as two critical constructs of organizations' cultural values, affect FP was examined with the mediating role of MC (composed of marketing planning capability (MPC) and marketing implementation capability (MIC)). Specifically, we derived specific conceptualizations on the effects of LO on FP through MO, MPC, and MIC as well as the effect of MO on FP through MPC. Accordingly, we empirically tested a process of how LO, MO, and MC translate into FP, using survey data of 146 respondents from Korean companies. The results successfully supported our model. It is worth noting not only that LO and MO are found to have synergistic effects on FP through MC but also that LO fosters MO. The relevant implications of our findings are presented with limitations and further research directions.

The purpose of this study is to demonstrate the moderating effect of technology development activities in the relationship between independent variables such as entrepreneurial orientation and technology innovation capabilities and dependent variables. As a result of analyzing the causal relationship between research variables, it was found that the higher the innovation and initiative among the sub-factors of entrepreneurial orientation, the more positive the technical commercialization performance and product completion. Among the sub-factors of entrepreneurial orientation, risk-taking was found to have a significant effect only on product completion. It was found that the higher the technology commercialization capability and technology convergence capability, the higher the technology commercialization performance, the technology commercialization performance. As a result of analyzing the moderating effect of technology development activities, it was found that technology development management ability, a sub-factor of technology development activities, controls the influence relationship between innovation and risk sensitivity and technology performance. In addition, it was found that the involvement in technology development planning controls the influence relationship between technology convergence capability and technology performance among sub-factors of technology innovation capability. Based on the above analysis results, this study made three suggestions as follows. First, the achievements of technology commercialization to achieve the superiority of corporate competition depend on progressive innovation and risk-taking based on entrepreneurial orientation. It is necessary to find a way to build entrepreneurial orientation from within the organization. Second, due to the nature of the ICT industry, which has a fast pace of technological development and changes in market acceptance, technology commercialization performance will be positive when the capabilities, technology, knowledge, and resources that can quickly lead to product production can be organically linked. Finally, corporate CEOs need to further promote innovation and risk-taking through phased and continuous research activities for technology development. In addition, it is necessary to establish a corporate culture that tolerates various strategies and failures so that understanding of technology convergence can lead to technological performance.

When asked about the success factors of successful entrepreneurs and celebrities, he says he was lucky. The remarkable fact is that the attitude about luck is different. However, despite the fact that the belief that we believe is lucky is actually a dominant concept, there has not been much scientific verification of luck. In this study, we saw good luck not being determined randomly by the external environment, but by being able to control luck through the internal attributes of individuals. This study is significant that we have empirically elucidated what kind of efforts have gained good luck, whereas previous research has largely ended in vague logic where luck ends up with an internal locus of control among internal entrepreneurial qualities and efforts can make a successful entrepreneur. We introduced the concept of good luck belief to avoid confirmation bias, which is, to interpret my experience in a direction that matches what I want to believe, and used a good luck belief questionnaire in previous studies and tried to verify that those who have a good belief can increase entrepreneurial opportunity capability through planned happenstance skills. The reason for choosing the entrepreneurial opportunity capacity as a dependent variable was based on the conventional research, that is, the process of recognizing and exploiting the entrepreneurial opportunity is an important part of the entrepreneurship research For empirical research, we conducted a questionnaire survey of a total of 332 people, and the results of the analysis turned out that the belief of good luck has all the positive impacts of planned happenstance skills' sub-factors: curiosity, patience, flexibility, optimism and risk tolerance. Second, we have shown that only the perseverance, optimism, and risk tolerance of planned happenstance skills' sub-factors have a positive impact on this opportunity capability. Thirdly, it was possible to judge that the sub-factors of planned happenstance skills, patience, optimism, and risk tolerance, had a meditating effect between belief in luck and entrepreneurial opportunity capability. This study is highly significant in logically elucidating that people in charge of business incubation and education can get the specific direction when planning a training program for successful entrepreneur to further enhance the entrepreneurial opportunity ability, which is an important ability for the entrepreneur's success.

This study investigates the effect of entrepreneurship on corporate performance highlighting the mediating role of technological innovation and the moderating role of marketing competence. By identifying the role of technological innovation and marketing competence within the relationship between the entrepreneurship and corporate's business performance, this study aims to improve SMBs' competence. Special attention was given to the fact that while there are some technology-based SMBs which have achieved positive outcomes through innovation, there are some other firms which have not been able to deliver expected outcomes despite of their technological competence. The data used in this study came from CEO or chief research executives of SMBs. Results of the data analysis show that the innovative sprit which is an important factor of entrepreneurship has an positive effect on technological performance, financial performance and non-financial performance. However, risk- taking tendency has an positive effect on technological performance but negative effects on financial and non- financial performance of the firms. This study also has examined the mediating effect of technological innovation on the relationship between entrepreneurship and corporate's performance and the result reveals that technological innovation plays a mediating role within the relationship. Specially, innovative spirit plays a full mediating role within the relationship between technological commercialization capacity and financial and non-financial performances of SMEs'. Also, risk taking tendency has a full mediating effect on the positive relationship between strategic planning capability and both financial and non-financial performance. Regarding the moderating role of marketing capability within the relationship between the entrepreneurship and the performance of the firms, results of data analysis shows as follows. Marketing professional capability plays a moderating role between risk taking tendency and performance of the firm and marketing structural capability plays a moderating role between innovative spirit and the performance of the firms. Based on these results, this study confirms that SMEs' business performance is effected by entrepreneurship. Innovative spirit plays a mediating role within the relationship entrepreneurship and business performance. However, Marketing capability has a partial moderating effect on the relationship between the entrepreneurship and the business performance.

While the amount of Official Development Assistance (ODA) in Korea has been increasing, there are some criticism about the effectiveness and management of ODA itself. The ODA in the area of Science, Technology and Innovation (STI) is also increasing but seems to have many problems. First, there is not clearly defined or agreed definition for STI ODA internationally as well as domestically. Second, the evaluation on the STI ODA performance is not enough. Third, the planning and management capability to implement ODA project is generally lacking. In this background, the issue of performance factors of STI policy consultation project was analyzed using the case studies and expert interviews. It is concluded that not only STI knowledge transferring capacity but also the absorptive capacity is important for the success of STI policy consultation project. In this sense, it is suggested to plan and manage the STI ODA project with the consideration of both transferring capacity and absorptive capacity.

This paper considers the Marine Traffic Risk Assessment for fixed and moving targets, which threaten officers during a voyage. The Collision Risk Assessment Formula was calculated based on a dynamic ship domain considering the length, speed and maneuvering capability of a vessel. In particular, the Navigation Risk Assessment Model that is used to quantitatively index the effect of a ship's size, speed, etc. has been reviewed and improved using a hybrid combination of a vessel's dynamic area and the Collision Risk Assessment Formula. Accordingly, a new type of Marine Traffic Risk Assessment Model has been suggested giving consideration to the Speed Length Ratio, which was not sufficiently reflected in the existing Risk Assessment Model. The larger the Speed Length Ratio (dimensionless speed), the higher the CJ value. That is, the CJ value is presented well by the Speed Length Ratio. When the Speed Length Ratio is large, states ranging from [Caution], [Warning], [Dangerous] or [Very Dangerous] are presented from a greater distance than when the Speed Length Ratio is small. The results of this study, can be used for route and port development, including dangerous route avoidance, optimum route planning, breakwater width, bridge span, etc. as well as the development of costal navigation safety charts. This research is also applicable for the selection of optimum ship routing and the prevention of collisions for smart ships such as autonomous vessels.
