특허권보호 강화가 기술혁신, FDI 및 경제성장에 미치는 영향
이성수 한국경영교육학회 2008 경영교육연구 Vol.49 No.-
This study investigates the impact of stronger patent rights protection on innovation, foreign direct investment and economic growth using the simultaneous equation model. The empirical study was conducted using a cross-country data set of 63 countries, of which 23 were developed countries and 40 were developing countries from 1970 to 1999. The estimation result shows that physical capital, R&D and FDI contribute to the economic growth, but stronger patent rights protection does not have a direct impact on economic growth. On the other hand, the system of patent rights protection plays a significant role for promoting innovation and the inflows of FDI, which indirectly affects the economic growth. The split sample of developed and developing countries indicates that innovation inducing role of patent rights protection is valid only for the developed countries and FDI inducing role is valid only for the developing countries. 본 논문은 특허권보호 강화가 기술혁신, FDI 및 경제성장에 미치는 영향을 연립방정식 모형을 이용하여 분석하였다. 1970-1999년 사이에 선진국 23개국과 개도국 40개국 등 총 63개국을 대상으로 실증분석 한 결과 실물자본, R&D, FDI 등이 경제성장에 긍정적인 영향을 미친 반면 특허권보호 강화는 경제성장에 직접적인 영향을 미치지 않는 것으로 나타났다. 그러나 특허권보호 강화는 기술혁신을 촉진시키고 FDI유입에 기여함으로서 간접적으로 경제성장에 기여한 것으로 나타났다. 소득수준별 회귀분석 결과 특허권보호 강화로 인한 기술혁신 유발효과는 선진국의 경우에만 유효한 것으로 나타났으며 FDI 유입효과는 개도국의 경우에만 유효한 것으로 나타났다.

In the field where factory automation facilities are employed, many facilities are organically built through automated control. To operate an automated facility, the factory staff should be trained regarding basic work and advanced technology. Accordingly, educational institutions have been including various technologies in their curricula, such as program design and communication, which are highly advanced technologies required for automation facilities. However, in the industrial field, work related to panel processing and wiring, which are categorized as basic skills necessary for beginner technicians, are required more commonly. In this study, the working conditions of the automation equipment operated in the industrial field and method of corresponding training activities were presented, and industrial field specific training activities were determined. As a result, it is expected that it will be possible to nurture the manpower necessary for the industrial field.

Influences of Time Perspective on Impulsive Purchase Tendency
이성수,Eugene Song 한국마케팅과학회 2011 마케팅과학연구 Vol.21 No.4
What make consumers act on impulse? Impulsive buying is a topic of interest not only to academic researchers but also to the people in the industry who can gain from bigger sales volume and to the consumer advocacy groups who regard impulse buying as an undesirable outcome from the excessive consumerism. While there are discrepancies in the definition of concept, generally speaking, impulsive buying is an unplanned and sudden purchase involving some urges, pleasures, and excitements (Rook, 1987). Previous research on this topic investigated consumers’ internal and external factors influencing the cognitive and emotional aspects of impulse buying. One stream of research focused on the cognitive aspects of impulse buying and emphasized the lack of planning and consideration before the purchase. Another aspect of impulse buying is that emotional factors are involved in the process (e.g., Beatty & Ferrell, 1998; Rook, 1987; Rook & Gardner, 1993; Wood, 1998) and it has been claimed that the internal stimuli such as urge, pleasure, and excitement, happening at the time of purchase bring impulse buying. In sum, it seems logical to consider both cognitive and emotional aspects as underlying factors influencing impulse buying tendency, but most research limitedly measured the cognitive aspect of unplanning (Cobb & Hoyer, 1986) or the emotional impulses (Rook, 1987), measured the impulse buying as a whole without distinguishing both (Beatty & Ferrell, 1998), or measured both external and internal aspects mixed together (Yeom & Kim, 2002). Thus, in the current study, cognitive and emotional aspects of the impulse buying are treated separately to determine each factor’s influences, respectively. Another less investigated area in impulse buying literature is the relationship between consumers’ time orientation and their tendency for impulse buying. Time plays a central role in human life and the concept of how people perceive time, time perspective or time orientation, has been thought to be crucial in their cognition, emotion, and behaviors. In particular, Zimbardo and his colleagues (e.g., Keough, Zimbardo & Boyd, 1999; Zimbardo, Keough, & Boyd, 1997) conceptualized time perspective as “the often nonconcious process whereby the continual flows of personal and social experiences are assigned in temporal categories that help to give order, coherence, and meaning to those events” (p. 1271). People use past, present, and future as time frames to form expectations and goals. Thus, time perspective affects a person’s attention, cognition, decision, and behaviors in a subtle, but crucial way (Zimbardo, 1988). Mischel (1974)’s Delay-of-gratification paradigm provides insightful explanations for the relationship between the time perspective and impulsive behaviors. Mischel and his colleagues (1974; 1989) compared the outcomes between affect-based and cognitive-based values in choice situations and found that the affect-based values were discounted much more sharply over time than the cognitive-based values. This finding implies that, for example, to decide whether or not to have a chocolate for dessert, satisfaction from eating a chocolate (emotional value) is usually more important than the possibility of gaining weight (cognitive value) in this decision making. However, if the decision is whether to have it or not one month later, (decision delayed for one month), concerns for possible weight gain count much more importantly than satisfaction. Decision making based on cognition compared to emotion tends to be more myopic and make people focus more on the present than the future. Previous studies support the argument that consumers’ time perspective affects their tendency for impulsive buying and planning and preparation are two crucial factors determining the occurrence of impulse buying. Based on these logics, two hypotheses are proposed. H1: Present time perspective would be positively related with both (a) cognitive a...

이성수 한국전자통신연구원 2003 ETRI Journal Vol.25 No.5
A multimedia SoC often requires a large internal buffer, because it must store the whole search window to reduce the huge I/O bandwidth of motion estimation. However, the silicon area of the internal buffer increases tremendously as the search range becomes larger. This paper proposes a new method that greatly reduces the internal buffer size of a multimedia SoC while the computational cost, I/O bandwidth, and image quality do not change. In the proposed method, only the overlapped parts of search windows for consecutive macroblocks are stored in the internal buffer. The proposed method reduces the internal buffer size to 1/5.0 and 1/8.8 when the search range is ±64×±64 and ±128×±128, respectively.
