As interest in drones controlled by remote technology rapidly increases worldwide, drones are used in many fields such as military, rescue, and transportation as future innovations in many countries. In particular, as the drone has been spotlighted as a new future strategic industry, it is also used for public purposes such as disaster relief and crime investigation. However, security concerns such as the penetration of major national facilities, collisions with aircraft, and the possibility of privacy infringement due to aerial photography are also being raised. Unlike the increased interest in drones, there have been few studies on drone use, drone safety, and public attitudes toward drone use. This paper analyzed the perceptions of drone attitudes, drone stability and policy support for drones for Korean and United Kingdom.

Mobile sinks are being exploited for various purposes for solving the hotspot problem. Thus, the mobility support technique of mobile sinks is important, and it has been studied steadily. A survey was conducted of studies of mobile sinks in sensor networks having different movement patterns depending on the applications. The related techniques were divided into three main categories according to mobility pattern: predefined, random, and control. In addition, communications for mobile sinks are strongly affected by whether there is a single mobile sink or multiple ones. Based on this two-level categorization, an overview is presented of some state-of-the-art mobility support techniques researched during the past three years, and then the technique are analyzed according to various criteria. Finally, this survey concludes with a summary and a discussion of some future research challenges.

The main characteristic of technology commercialization by technology-intensive SMEs is that its success is highly uncertain due to the low maturities of their technology and market. Therefore, in order to find out more effective policy, it is essential to understand the technology commercialization in terms of the institutional support system including innovation policy, rather than an individual firm's strategy. Focusing on the Daeduk Innopolis, where many technology-intensive firms agglomerate, this paper explores SMEs' behavior for technology commercialization and the innovation system in the regional level. Then it points out the limitations and problems of the technology commercialization system in Daeduk innopolis, which might be closely related to the 'system failure' in the transition period. Based on the results of this innovation system approach, this paper also suggests some policy directions and agendas for overcoming those system failures in technology commercialization.

This paper focuses on the systematic approach to handle possible resistance by the members of an organization which adopts ERP system. We also analyze various factors that affect the members' receptivity to the new system. The analytic result from the data of 169 universities shows that emotional factors such as fear and doubt play a significant role, while other factors such as relative advantages of efficiency, relative advantages of system and technology support does not. This research demonstrates both the psychological and behavioral aspects of resistance to technology, and then provides a new perspective on the adoption and diffusion of technological innovation in an organization by systematically analyzing the possible negative consequences while the majority of existing research emphasizes on the rosy prospects of the innovation.

This study examined the success factors of six sigma innovation in small- and medium-sized venture companies. The findings are summarized as follows. The importance of 20 items in a total of 4 factors showed that corporate vision was number one in the manager's support, followed by program composition, passionate support, high performance guarantee, and quality activity continuity. This suggests that all members can operate the program by the structured system with a sense of united goal under the company-offered vision as a community when the goal, idea or vision of six sigma activities are shared to members of the entire organization. In addition, high success can be achieved when supported by company-wide enthusiasm and high compensation for sharers' innovative efforts of six sigma at the same time. Small- and medium-sized venture companies should develop brisk six sigma activities of advanced precision parts in such an environment that the technology competition is becoming increasingly fierce. The six sigma movement should be developed as a niche strategy for small organizations with united vision sharing by company-wide operational commitment and high self-esteem for the organizational characteristics of small- and medium-sized venture companies run by key minority organizations and members.

This paper empirically examines the effect of government R&D support on the performance of the firm in Korea. In particular, we examine to what extent the government R&D support affected the firm's exploratative performance. Using a novel dataset combining patent information with national government R&D funding data and firm performance indicators from 2005-2008, we construct and run an empirical model where a firm's exploratative activity, measured by a firm patenting in a different field, is a function of the government R&D support a firm receives. The empirical results show that the government R&D support has a positive effect on the firm's exploratative activity. Especially, this effect is stronger for the small and medium size firms, while large firms are relatively relying on their own R&D funding for exploration. This result indicates that the government needs to focus more on R&D funding for small and medium size firms, if it wants more exploratative outcomes to enhance potential resources for economic development.

The government has supported the innovation of private firms by intervening the market for various purposes, such as preventing market failure, alleviating information asymmetry, and allocating resources efficiently. Although the government's R&D budget increased rapidly in the 2000s, it is not clear whether the government intervention has made desirable impact on the market. To address this, the current study attempts to explore this issue by doing a systematic literature review on foreign and domestic papers in an integrated way. In total, 168 studies are analyzed using contents analysis approach and various lens, such as policy additionality, policy tools, firm size, unit of analysis, data and method, are adopted for analysis. Overlapping policy target, time lag between government intervention and policy effects, non-linearity of financial supports, interference between different polices, and out-dated R&D tax incentive system are reported as factors hampering the effect of the government intervention. Many policy prescriptions, such as program evaluation indices reflecting behavioral additionality, an introduction of policy mix and evidence-based policy using machine learning, are suggested to improve these hurdles.

The present paper describes a general procedure of the structural safety assessment for the independent type C tank of LNG bunkering ship. This strength assessment procedure consists of two main scheme, global Finite Element Analysis (FEA) model primarily for hull structure assessment and detailed LNG Tank structures FEA model including the cylindrical tank itself and saddle-support structures. Two kinds of mechanism are used, fixed and slides constraints in fore and rear of the saddle-support structures that result in a variation of the reaction forces. Finite Element (FE) analyses have been performed and verified by the strength acceptance criteria to evaluate the safety adequacy of yielding and buckling of the hull and supporting structures. The detail of FE model for an LNG type C tank and its saddle supports was made, which includes the structural members such as cylindrical tank shell, ring stiffeners, swash bulkhead, and saddle supports. Subsequently, the FE buckling analysis of the Type C tank has been performed under external pressure following International Gas Containment (IGC) code requirements. Meanwhile, the assessment is also performed for yielding and buckling strength evaluation of the cylindrical LNG tank according to the PD 5500 unfired fusion welded pressure vessels code. Finally, a complete procedure for assessing the structural strength of 500 CBM LNG cargo tank, saddle support and hull structures have been provided.
