스마트폰의 일상화로 모바일 중심의 라이프 스타일이 확산되면서, 모바일을 기반으로 하는 모바일 뱅킹, 쇼핑 등의 이용이 증가하고 있다. 또한 최근 금융과 IT기술이 결합된 신조어인 Fintech(Financial + Technology)의 등장과 함께, IT기반의 금융시장은 더 확대될 것으로 보인다. 이러한 추세에 따라서, 지급결제 수단으로서의 모바일 신용카드에 대한 기업 및 국가적 차원의 관심 및 투자가 증가하고 있으나, 소비자의 실제적인 확산 및 이용은 낮은 수준에 있다. 이러한 점을 고려하여 본 연구에서는 모바일 신용카드 이용 및 확산을 위한 요인이 무엇인지를 파악하기 위하여 확산이론(Innovation Diffusion Theory)과 후기수용모형(Post Acceptance Model)을 바탕으로 연구모형을 구성하였다. 설문조사를 통해 분석 자료를 수집하고, 연구모형을 분석한 결과, 인지된 용이성, 이미지, 적합성, 촉진의 4가지 요인이 사용자 만족에 유의한 영향을 미치는 것이 확인되었다. 또한, 모바일 신용카드에 대한 사용자 만족은 모바일 신용카드 지속사용의도에 유의한 영향을 미치는 것으로 나타났다. 또한 집단 간 비교연구에서는 플라스틱 신용카드보다 모바일 신용카드 이용금액이 많은 집단에서 촉진이 사용자 만족에 더 큰 영향을 미치는 것으로 나타났으며, 상대적으로 모바일카드 이용금액이 적은 집단에서는 인지된 용이성과 이미지가 사용자 만족에 더 큰 영향을 미치는 것으로 나타났다. 본 연구결과는 모바일 신용카드 활성화를 위한 정부 및 기업의 마케팅에 있어서의 전략적 가이드라인을 제공할 것으로 기대하며, 또한 상대적으로 부족한 모바일 신용카드 연구에 초기 단계 연구로서의 가치를 지닐 것으로 기대한다.

The purpose of this study is to figure out the impacts of technological innovation and cost management on productivity in small shipping industries to come up with developmental implications. To achieve this, a survey was carried out to 150 workers in small shipbuilding industries through April 2 to April 20, 2012. As for findings stated above, technological innovation and cost management in the Korean small shipbuilding industries were key factors that elevate financial and non-financial productivity. In the light of low technological prowess and cost structure of small shipbuilding industries, their productivity can be improved when intensive cost management with production factor technology as know-how is realized through quality management, which product development technology is the top priority as an independent niche strategy. Consequently, the combination of infrastructures in small shipbuilding industries with continuous efforts for cost reduction by the link to the systematized structure can't only secure their independent competitiveness, but raise their productivity.

This paper has investigated the effects of employees' organizational cynicism on their organizational commitment and pro-union behavioral intentions in the context of repetitively implementing business innovation program. The cynical responses about the business innovation program & projects have been classified into four categories; Exit, Voice, Loyalty and Neglect. The research samples have been drawn from managers and office employees at four business sites of conglomerates in Korea. According to the analysis, business innovation program which is continuous and repetitive has made managers and office employees have highly cynical attitudes. In turn, the organizational cynicism has accelerated their Exit and Neglect responses, but shrunk Voice and Loyalty responses. As a result, it has been confirmed that the organizational cynicism has a direct effect on organizational commitment and pro-union behavioral intentions. In addition, it has been concluded that Exit and Neglect had a negative effect on organizational commitment but a positive effect on pro-union behavioral intentions. Even though Voice and Loyalty had a positive effect on organizational commitment, they had no significant effect on pro-union behavioral intentions. Furthermore, no mediating effect has been detected. Implications and suggestions for future research were then discussed.

To investigate the seismic pounding response of long-span bridges with high-piers under strong ground motions, shaking table tests were performed on a 1/10-scaled bridge model consisting of three continuous spans with rigid frames and one simply-supported span. The seismic pounding responses of this bridge model under different earthquake excitations including the uniform excitation and the traveling wave excitations were experimentally studied. The influence of dampers to the seismic pounding effects at the expansion joints was analyzed through nonlinear dynamic analyses in this research. The seismic pounding effects obtained from numerical analyses of the bridge model are in favorable agreement with the experimental results. Seismic pounding effect of bridge superstructures is dependent on the structural dynamic properties of the adjacent spans and characteristics of ground motions. Moreover, supplemental damping can effectively mitigate pounding effects of the bridge superstructures, and reduce the base shear forces of the bridge piers.

This study began the study by instructing enterprises to change Batch Production into U-Line. This study suggested TPS U-Line building model process and applied it to some of their product line. By connecting concerned process elements into continuous operations. Outside orders were also switched to inside operations and executed in continuous operations, thereby about 100Km of transit distance became zero Km, Production lead Time was incredibly reduced. After all, 90% of Production Lead Time, 50% of handling fault, 3/4 of workers decreased and Productivity per Person enhanced which involves improving Batch Production into Continuous Production and applies it to the real world, so that small and medium enterprises can consult this study if the company is willing to make an improvement to their product line.

Continuous usages of Internet Protocol Television(IPTV) is regarded as one of key factors for IPTV success. Quality improvement and increasing user satisfaction are generally contributed to intention to continue using of innovation technology. We classify the quality constructs into information quality, service quality, system quality, and experience quality and find how these constructs affect on user satisfaction and intention to continue using of IPTV. We perform factor analysis to IPTV users by developing a causal relationship model and defining measurement variables for the constructs. Through regression analysis, we found information quality and experience quality are significant to affect on intention to continue using of IPTV.

A hybrid bridge deck is proposed, which includes steel bars, concrete and glass-fiber-reinforced-polymer (GFRP) plates with channel sections. The steel bar in the negative moment region can increase the flexural stiffness, improve the ductility, and reduce the GFRP ratio. Three continuous decks with different steel bar ratios and a simply supported deck were fabricated and tested to study the mechanical performance. The failure mode, deflection, strain distribution, cracks and support reaction were tested and discussed. The steel bar improves the mechanical performance of continuous decks, and a theoretical method is proposed to predict the deformation and the shear capacity. The experimental results show that all specimens failed with shear failure in the positive moment region. The increase of steel bar ratio in the negative moment region can achieve an enhancement in the flexural stiffness and reduce the deflection without increasing GFRP. Moreover, the continuous deck can achieve a yield load, and the negative moment can be carried by GFRP plates after the steel bar yields. Finally, a nonlinear analytical method for the deflection calculation was proposed and verified, with considering the moment redistribution, non-cracked sections and nonlinearity of material. In addition, a simplified calculation method was proposed to predict the shear capacity of GFRP-concrete decks.
