현재 학생 수 감소로 인해 대학별로 경쟁력을 높이기 위한 다양한 노력들을 기울이고 있는데, 특히 대학의 핵심서비스인 수업만족도 향상은 경쟁력에서 중요한 부분이다. 이런 중요성으로 인해 수업만족도에 대한 연구가 진행되고 있으나, 수업의 감정적 부분에 관한 연구는 거의 없다. 만족도의 중요한 요인이 감정임을 볼 때, 수업도 마찬가지로 이러한 감정의 영향을 살펴볼 필요가 있을 것이다. 따라서 본 연구에서는 많은 연구에서 만족의 선행요인으로 확인된 PAD(Pleasure, arousal, dominance)를 대학수업에 적용하여 대학 수업의 감정적 측면을 부각시키고자 한다. 또한 이러한 감정을 자극하는 변수로서 교수실재감과 교수-학습자 상호작용, 학습자간 상호작용을 제시하고 PAD와 수업만족도와의 관계를 설정하고 검증하였다. 219명의 대학생 표본을 구조방정식 모형을 이용해 분석한 결과, 교수실재감은 교수-학습자 상호작용에 영향을 주고, 즐거움, 각성, 지배감과 같은 감정에 긍정적 영향을 주는 것으로 나타났다. 그리고 교수-학습자 상호작용은 즐거움과 각성에 영향을 주고, 학습자간 상호작용은 즐거움, 각성, 지배감에 긍정적 영향을 주는 것으로 나타났다. 마지막으로 즐거움, 각성, 지배감은 모두 수업만족도를 유의하게 증가시키는 것으로 나타났다. 이러한 연구결과는 주로 수업의 인지적 부분에 집중하던 기존 연구에 다른 시각을 제공해주며, 수업만족도를 높이기 위한 방법에 있어 감정을 자극하는 다양한 프로그램이나 수업방식을 개발해야 한다는 시사점을 제공한다.

Purpose - This study investigates whether the effectiveness of self trait-advertisement versus communion-focused advertisement on product evaluations depends on a type of pride felt as ambient emotion. It also explores whether the mediating roles of cognitive and affective response to the effect of the advertisement type on product evaluation are moderated by types of pride such as hubristic pride or authentic pride. Research Design, Data, and Methodology - This research uses a restaurant service as the experimental object and employs a 2 (pride type: hubristic pride vs. authentic pride) × 2 (advertisement type: self trait-focused advertisement versus communion-focused advertisement) between-subjects design, with cognitive response and affective response as within-subject. Each experimental group consisted of 40 undergraduate students assigned to participate in the experiment. One questionnaire from the authentic pride and self-trait focused advertisement group and two questionnaires from the hubristic pride and communion-focused advertisement group were removed due to answer errors, resulting in a participant number of 157. The author conducts a 2 (pride type: hubristic pride vs. authentic pride) × 2 (advertisement type: self trait-focused advertisement versus communion-focused advertisement) ANOVA on advertised product evaluations, and to better understand the interaction effects, also conducts separate analysis of the hubristic and the authentic pride groups. Additionally, the study conducts mediated moderation analysis to check the mediation role difference of the cognitive response and the affective response to each advertisement on the interaction effects on product evaluations between the hubristic and the authentic pride groups. Results - The findings indicate that participants in the hubristic pride group more positively evaluate the product in self-trait focused advertisement, whereas participants in the authentic pride group more positively evaluate the product in communion-focused advertisements. In addition, the mediating role of cognitive response on the positive interaction effect of advertisement type and pride type on product evaluation is partially moderated by the pride type. However, the mediating role of affective response on the positive interaction effect of advertisement type and pride type on the product evaluation is not moderated by the pride type. Conclusions - The results of this study contribute to advertisement theory development by exploring interaction effects of ambient pride type and advertisement type on product evaluation, as well as to the theory of consumer behavior by exploring how pride type moderates the mediating roles of cognitive response on the positive interaction effect of advertisement type and pride type on product evaluation. From the perspective of the current research, advertisers should research what kinds of events consumers have experienced to increase the effectiveness of their advertisements, and use self-trait advertisements when consumers are grouped under ambient hubristic pride, and use communion-focused advertisements when consumers are grouped under ambient authentic pride. However, future research is necessary to discover the reasons why the mediating role of affective response to advertisements in the interaction effects of pride type and advertisement type on product evaluation is not moderated by pride type.

Although the interaction effects of knowledge sourcing strategies vary depending on environmental conditions such as knowledge intensity, most prior empirical research have failed to prove the effects of environmental conditions on the relationship between knowledge sourcing strategies and firm performance. In order to fill this gap, this study examines how knowledge intensity affects the relationship between knowledge sourcing strategies and firm performance. The results of this study indicate the interaction effects of knowledge sourcing strategies in high knowledge intensity environment are different from the effects in low knowledge intensity environment. This study expands knowledge management research by identifying the effects of knowledge intensity on the relationship between knowledge sourcing strategies and firm performance. Furthermore, it offers valuable practical guidelines for managers in selecting successful combinations of knowledge sourcing strategies with the consideration of knowledge intensity.

Purpose: This study was conducted to investigate the effects of multimodal sensory stimulation on growth and mother-infant interaction in infants with low birth weight (LBW). Method: A non-equivalent control group time-series study design was used. The participants were 38 LBW infants and their mothers (19 in the intervention group and 19 in the control group). The data were collected from September 1, 2003 to March 31, 2004. For the mothers in the intervention group, this researcher instructed mothers in the multimodal sensory stimulation therapy, in turn the mothers used these techniques on their infants once a day during the 4-week research period. The researcher measured weight, length, and head circumference of the LBW infants once a week for 4 weeks and made a film of the mother playing with the infant for 5 minutes in the last week of the research period. Results: Compared to the control group, LBW infants in the intervention group showed significant increases in weekly weight gain (F=3.82, p=.012) and had significantly higher scores for mother-infant interaction (t=3.93, p>.000). Conclusion: The results suggest that multimodal sensory stimulation therapy can be used to increase the growth of LBW infants and improve mother-infant interaction.

The attitude aerodynamic control is an important subject in the design of an aerospace plane. Usually, at high altitudes, this control is fulfilled by thrusters so that the implementation of an aerodynamic control of the vehicle has the advantage of reducing the amount of thrusters fuel to be loaded on board. In the present paper, the efficiency of a wing-flap has been evaluated considering a NACA 0010 airfoil with a trailing edge flap of length equal to 35% of the chord. Computational tests have been carried out in hypersonic, rarefied flow by a direct simulation Monte Carlo code at the altitudes of 65 and 85 km, in the range of angle of attack 0-40 deg. and with flap deflection equal to 0, 15 and 30 deg.. Effects of the flap deflection have been quantified by the variations of the aerodynamic force and of the longitudinal moment. The shock wave-boundary layer interaction and the shock wave-shock wave interaction have been also considered. A possible interaction of the leading edge shock wave and of the shock wave arising from the vertex of the convex corner, produced on the lower surface of the airfoil when the flap is deflected, generates a shock wave whose intensity is stronger than those of the two interacting shock waves. This produces a consistent increment of pressure and heat flux on the lower surface of the flap, where a thermal protection system is required.

This study is to analyze the impact of the absorptive capacity and information technology (IT) on firms' innovation. The absorptive capacity is measured by R&D investment intensity, R&D manpower concentration, and the firm's size. We try to see the interaction effects between the absorptive capacity and IT usage on firms' innovation. We also look into the differences of the impacts between manufacturing industry and service industry as well as IT industry and service industry. We found that IT and R&D intensity have stronger interaction effect on innovation in manufacturing industry than in service industry, which shows that IT plays a more important role in the accumulation of knowledge in R&D activity in manufacturing industry. Contrarily, in service industry, IT and R&D manpower concentration has significant interaction effects on innovation. This means that the role of IT in service industry is sharing knowledge and experiences among employees in service industry. The interaction effect between firm's size and IT has positive impact on innovation in manufacturing industry, while it has negative impact on innovation in service industry. Finally, we found that the interaction effect is statistically significant in non-IT industry, while it is not statistically significant in IT industry.

Purpose: The purpose of this study was to investigate the effects of sensory stimulation conducted by primiparas on mother-infant interaction, maternal self-esteem and infant temperament. Method: A non-equivalent control group post-test study design was used. The data were collected from December 1, 2001 to March 30, 2003. The participants were 39 primiparas with normal birth weight infants. They were divided into two groups, 20 mothers in the intervention group and 19 in the control group. The mothers in the intervention group were given instruction on sensory stimulation by the researcher, and the mothers, in turn, used this technique on their infants twice a day during the first 2 months of life. Both groups were measured for maternal self-esteem and infant temperament using the maternal self-report inventory (MSRI) and What My Baby Is Like (WBL) and a film was made of the feeding situation when each infant was between 8 and 10 weeks of age. Results: Compared to the control group, the experimental group had significantly higher scores in mother-infant interaction, maternal self-concept and infant temperament. Conclusion: This suggests that sensory stimulation conducted by primiparas may improve the mother-infant interaction, maternal self-esteem and infant temperament.

Contrast to the conventional jointed bridge design, integral abutment bridges (IABs) offer some marked advantages like reduced maintenance and enhanced service life of the structure due to elimination of joints in the deck and monolithic construction practices. However, the force transfer mechanism during seismic and thermal movements is a topic of interest owing to rigid connection between superstructure and substructure (piers and abutments). This study attempts to model an existing IAB by including the abutment backfill interaction and soil-foundation interaction effects using Winkler foundation assumption to determine its seismic response. Keeping in view the significance of abutment behavior in an IAB, the probability of damage to the abutment is evaluated using fragility function. Incremental Dynamic Analysis (IDA) approach is used in this regard, wherein, nonlinear time history analyses are conducted on the numerical model using a selected suite of ground motions with increasing intensities until damage to abutment. It is concluded from the fragility analysis results that for a MCE level earthquake in the location of integral bridge, the probability of complete damage to the abutment is minimal.
