Artificial intelligent (AI) smart speaker sales have increased rapidly, and AI technology has become more pervasive in our daily lives. This study explored motivations for smart speaker use and examined how motivation and relationship type with AI speakers affect enjoyment. Smart speaker use is primarily motivated by conversational, trend-leading, efficient, and entertaining factors. Among these four, trend-leading, efficient, and entertaining factors positively influenced users' enjoyment. However, among the three types of relationship with AI speakers, only the assistant/helper type affected enjoyment. The results of the current study provide practical implications for future directions in AI speaker interaction design.

The purpose of this study is to analyze the status of various government support policy for IoT sector and survey the level of satisfaction and relative importance among policies. In order to achieve the goal, this study surveyed experts in the field of IoT, utilizing Hierarchy Process Analysis methods. Major findings are as follows; first, despite of wide range of IoT-related policies, experts in the industry and academy are very limited, ; second, the order of policy satisfaction is primarily on Oversea Marketing, followed by R&D support, Venture support, Human resource education.; third, the order of importance is primarily Venture support, followed by R&D support, Human resource education. Also, it has been given the higher importance to the role of leader as R&D support, Oversea market pioneering, and industry university network, rather than the role of coordinator and supporter. However, expert group does not recognize the importance of policies related to the role of coordinator because these policies always have been conducted in major government projects.

In recent times, there has been considerable interest in HIPS (High Impact Polystyrene) materials for their use in construction of office equipments, home electronics, housing for electronics appliances, packing containers, etc. However, these materials suffer from problems caused by fatigue fracture. Further, their strength is substantially affected by environmental conditions. Therefore, in this study, the effect of temperature was analyzed by performing a tensile test and a fatigue test. It was observed that the yield strength, the ultimate strength, and the fatigue life decreased relatively with an increase in temperature. Further, an S-N curve can be predicted by using the results of the tensile test and a micro-Vickers hardness test.

This paper examines the development of smelting reduction process in POSCO from 1990 to 2007 with the perspective of post catch-up technological innovation. POSCO paid attention to smelting reduction process as a sort of next-generation iron and steel technology, and implemented COREX (coal ore reduction) by the cooperation with V$\"{o}$oest. In addition to this, POSCO started to develop FINEX (fine iron ore reduction) which can use abundant powder ore, and FINEX was developed through model plant, pilot plant, demo plant, and commercial facility. POSCO came up to innovation leader beyond fast follower by securing almost technologies concerning FINEX. The case of smelting reduction process shows various characteristics including appropriate technological choice, successive scale-up, spiral development system, complementary technological cooperation, long-tenn investment, the existence of top management's leadership, and Korean government's support in early stage. This case can be interpreted as a path-revealing innovation in the middle of technological paradigm change.

The Korean innovation ecosystem has evolved from a catch up stage to a creative leader stage where government's role in creating a private sector driven, healthy and dynamic ecosystem is important. Korea's innovation ecosystem shows a stagnation of innovation performance and a lack of linkage activities within the national innovation ecosystem and in global cooperation, despite the dramatic advancement and expansion of the ecosystem. A next-generation innovation ecosystem model is required to create a future-oriented innovation ecosystem. The next generation innovation ecosystem was prepared on the basis of the framework, which has 6 elements among which inter-firm network is the the micro-foundation of the ecosystem. On the basis of the framework, assuming that the next generation innovation ecosystem is the evolved existing ecosystem, responsive the discontinuous change in market and technology, which is private sector driven healthy and dynamic ecosystem, the next generation innovation ecosystem model was created. The concrete details on the direction of the policy entities responsible for building the ecosystem was presented, and the contribution of this study was discussed.

Along with technological innovation, successful market entry of a new product is important for sustainable innovation of a firm. In this paper, we examined factors that affect successful introduction of new branded drugs in pharmaceutical industry. Under competing theories of the first mover's advantage and the late mover's advantage, this research focuses on how latecomers can overcome the disadvantages of late entry and catch up to the market leader. First, late movers can absorb the knowledge leaked from pioneering product during the time lag between early entrants and late entrants. Therefore, the time lag provides late entrants an opportunity to catch-up to market leader by differentiating and improving the quality of new product. Second, superior marketing capability of late entrants can enhance the possibility of catching-up, by overcoming the consumer base of early entrants.

Characterisation of the stress-strain relationship as well as crashworthiness of cellular polymer was investigated under constant impact energy with different velocities, considering inertia and strain rate effects simultaneously during the impact testing. Quasi-static and impact tests were carried out for two different density (64 $kg/m^3$, 89 $kg/m^3$) cellular polymer specimens. Also, the equations, coupled with the Sherwood-Frost model and the Impulse-Momentum theory, were employed to build the constitutive relation of the cellular polymer. The nominal stress-strain curves obtained from the constitutive relation were compared with results from impact tests and showed to be in good agreement.

대부분의 사람들은 한국마사회를 '경마시행기관' 정도로 알고 있다. 하지만 이는 사실 매우 그릇된 인식이다. 60년 역사를 자랑하는 마사회는 공공기관으로서 마필개량 및 증식, 생활승마 보급 등 공익적 측면에서 많은 일을 하고 있다. 또한 승마사업, 장구제조, 식육가공, 향장품 생산 등 말 산업의 육성에도 적극 나섬으로써 국가 경제 발전과 고용 창출에도 기여하고 있다. 즉 경마는 마사회가 운영하고 있는 큰 들의 말 산업에서 하나의 사업분야에 불과한 셈이다. 이처럼 여러 선도적인 공익사업으로 빛나는 마사회지만 실은 마사회를 더욱 값지게 하는 것이 하나 더 있다. 그것은 바로 안전이다. 이곳은 그간 '건강하고 행복한 근로자, 안전한 일터 KRA'라는 슬로건 아래 적극적인 안전보건활동을 펼쳐 세간의 많은 주목을 받아왔다. 공공기관답게 깨끗하고 청렴한 안전관리관리를 선보이겠다는 마사회를 찾아가 봤다.
