  • In this paper, a research model was designed to investigate the factors influencing the intention to use of mobile easy payment services in China. Our research model includes the service factors(instant connectivity, economic and security), social factors(subjective norms and image), the user's individual factors(self-efficacy personal innovativeness and suitability), perceived ease of use, perceived usefulness and intention to use. A survey was conducted to collect the data with users who have had the actual using experience about mobile easy payment services. In this research, the data were collected by online survey, and in final analysis, 439 users' questionnaires were used. The empirical paper proves research hypothesis by using SPSS 22.0 and AMOS 23.0. The results of the study are as follows: the mobile easy payment service factors, social factors and the user's individual factors partially give positive effects to perceived ease of use and perceived usefulness; perceived ease of use gives positive effects to perceived usefulness. In addition, perceived ease of use and perceived usefulness have positive effects to on intention to use.

  • The present research investigates the reciprocal effects of a previous brand extension and follower brand extension's market performance on a parent brand of a follower brand's extension product using 2(previous brand extension's market performance: success vs. failure)${\times}$2(follower brand extension's market performance: success vs. failure) between-subjects factorial design. The verification of the hypothesis is composed through 2-way ANOVA. As a result, the consumers' evaluation of the parent brand of a follower brand's extension product when the follower brand's extension succeed was more positive when the previous brand's extension has failed. However, when the follower brand's extension has failed, the consumers' evaluation of the parent brand of a follower brand's extension product was more negative when the previous brand's extension has succeeded.

  • This study was conducted to test whether the education program consisted with knowledge about professional care for elderly and content of elderly simulation experience to improve empathy had positive effects on attitude and intention to practicing nursing care toward elderly. According to the study results, It was appeared that the experimental group provided both knowledge and elderly simulation experience showed more positive attitude toward elderly(t=2.56, p=.026) and intention to practicing nursing care for elderly(t=6.73, p=.003), compared with the group provided knowledge only. However, after experiencing elderly simulation program, the attitude toward elderly(t=1.22, p=.170) and intention to practice nursing care for elderly(t=-0.08, p=.470) in experimental group improved very little or so, whereas the attitude toward elderly(t=-2.33, p=.012) and intention to practice nursing care for elderly(t=-1.08, p=.150) in comparison group became even worse.

  • This research was designed to verify the causal relationships between organization managers' unmet expectations and job burnout and the mediating effects of overcommitment based on the effort-rewards imbalance theory. It was also intended to evaluate the moderating effect of LMXSC on the relationship between overcommitment and job burnout. 172 branch managers working at commercial bank were selected as the target research group. This study was validated by The SPSS 24.0, the reliability was justified through the factor analysis, and the casual relationship was confirmed through the three-step regression. As a result, unmet expectations had a strong positive correlation with job burnout and overcommitment. Overcommitment had a strong positive correlation with the mediating effect between unmet expectations and job burnout. Moderating effects of LMXSC were not significant. This study showed the practical implication between unmet expectations, overcommitment, and job burnout. Additionally it exhibited the job design and management practice in manager groups where the importance of their role has been expanded. Lastly, we found the interdisciplinary implication from making an effort to elaborate the antecedent of variables.

  • As it recently appears that LCC (Life Cycle Cost) analysis may be considered as an essential method for economic evaluation of infrastructures. Many researches have been made to assess LCC of each facility based on reasonable methods. However, expected maintenance repair cost must be reasonably estimated to enhance the reliability of LCC analysis through systematic and rational methods. This study is intended to propose a rational approach to reliability-based LCC analysis of high-speed railway steel bridges considering lifetime corrosion and fatigue damage. However in Korea, since high speed railway steel bridges are only recently constructed, no direct statistical data are available for the account of the maintenance cost and thus their maintenance characteristics are not clear yet. In this paper, for the assessment of expected maintenance/repair cost, the fatigue system reliability analysis incorporating the corrosion effect is proposed by considering the corrosion and fatigue damage using measured data of high speed railway steel bridges. A model proposed by Rahgozar, of at for fatigue notch factor considering the corrosion effect is used in order to incorporate the corrosion effect into the fatigue strength reduction and S-N curve. Finally, the effectiveness of LCC model proposed for high-speed railway steel bridges is demonstrated by a numerical example.

  • 본 연구는 서비스 교육성과에 미치는 영향으로 성격의 요안을 살펴봄으로써 서비스 지향적인 직원들의 채용 및 서비스 교육의 방향에 대해 연구하자 하였다. 최근 기업 간의 경쟁이 치열해 지면서 고객들에게 제품이외의 것을 제공하여 고객만족을 통한 차별화에 관심을 주기 시작 하였다. 이라한 기업들은 '고객만족' 을 위해 물리적 자원과 서비스 제공자의 인적자원을 포함하여 광범위하게 노력을 기울였다. 그러나 변화무쌍한 고객의 기대에는 더 광범위한 노력이 필요하였다. 따라서 인적자원의 노력이 필요하였다. 특히 서비스를 제공하는 기업에는 고객의 접점에서 일하는 직원들의 수행능력이 고객의 기대에 만족을 줄 뿐만 아니라 기업의 이미지에도 영향을 마찰 수 있기 때문에 직원들의 고객 지향적 사고 및 행동은 고객만족에 영향을 주는 하나의 요소로 볼 수 있다. 특히 접점에서 대면하는 직원들의 지속적인 서비스 교육을 통해서 기본적인 고객응대와 고객 지향적인 사고를 전달하여 기업의 경쟁력을 향상시치고 변화하는 고객의 기대에 부응하고자 노력하고 있다. 이에 따라 본 연구에서는 이론적 근거를 토대로 연구모형을 설계하고 가설 검증을 하기 위해 유통서비스에서 1회 이상의 서비스교육을 받은 접점의 직원들을 대상으로 설문지를 배포하여 성격과 서비스 교유의 전과 후 성과 빚 서비스 교유 횟수에 대해 조사하였다. 본 연구의 실증분석 결과는 다음과 같다. 첫째, 성격과 서비스 교육성과에 미치는 영향을 볼 때 성취지향성 (ambition), 배려성(likeability), 신중성 (prudence)은 서비스교육성과에 영향을 미친다고 나타났다. 이는 직윈 채용에 있어 성격요인 분석을 할 필요성이 있을 것으로 생각된다. 서비스 지향적인 사고를 지니고 있고, 서비스 교육을 지속적으로 진행하는 기업의 특성에 맞는 직원을 채용함으로써 교육성과의 극대화와 기업의 이익창출 빚 이미지제고의 긍정적인 영향을 줄 것으로 기대된다. 둘째, 서비스 교유 횟수가 성격과 서비스 교육성과 간의 조절 작용 여부를 검증할 결과 성취지향성 (ambition), 사회성 (sociability), 지적호기심(intellectance) 이 조절 작용을 하는 것으로 나타났다. 즉 직원의 특성에 맞는 적절한 교유 횟수에 대한 방안을 모색할 수 있을 것으로 기대된다. 또는 집단 안에서 비슷한 성격의 직원들로 구성하여 그 구성원들의 서비스 교육진행에 있어 교육 횟수를 조절한다면 서비스 교육의 성과를 극대화 할 수 있을 것으로 예상할 수 있다. 마지막으로 교육생의 학력수준이 성격과 서비스 교육성과 간의 조절 작용여부를 검증한 결과 학력과는 무관한 것으로 나타났으며, 이는 교육생의 학력수준으로 서비스 교육의 성과를 결정하는 요소가 아님을 알 수 있다.

  • This paper describes a detailed assessment of the structural safety, serviceability, capacity rating and long-term performance of a glass fiber-reinforced polymer (GFRP) slab bridge superstructure. This first all-GFRP slab bridge was installed in Korea on May 2002. The GFRP slab bridge is a simply supported, its length is 10.0 m, and is designed to carry two-lane traffic and has an overall width of 8.0m. The GFRP slab bridge is a sandwich structure with a corrugated core, fabricated by hand lay-up process with E-glass fibers and vinyl ester resins. The assessment of long-term performance for the GFRP slab bridge in 2004, 2011 includes a field load testing identical to that performed in 2002. The assessment indicates that the GFRP slab bridge has no structural problems and is structurally performing well in-service as expected. The assessment may provide a baseline data for the capacity ratings assessment of the GFRP slab bridge and also serve as part of a long-term performance of all-GFRP bridge superstructure.

  • Two promoters (trc and P$\rho$) were inserted in PHA operon derived from Alcaligenes eutrophus to obtain high chain molecules of polyhydroxybutyrate (PHB) in recombinant Escherichia coli. Newly designed PHA operon was used to control the gene expressions of hydroxybutyric CoA and PHA polymerization, separately. Plasmids containing new synthetic operon was transformed into E. coli DH5$\alpha$ and analyzed for PHB production. Without induction of the PHA biosynthetic operon, PHA synthase which has low activity might supply low concentration of initiator during the polymerization reaction, resulting very high molecular weight of polymer. An increase of PHB average molecular weight was observed with decreased IPTG (isopropyl $\beta$ -Dithiogalactosidase) concentration. When no IPTG was added to the culture of E. coli DH5$\alpha$ /$\rho$ SJS1 which contained two promoters in PHA operon, high chain polymer having an average molecular weight of $2.5{\times}10^7$ was achieved. Analysis of the enzyme activities of PHA biosynthetic enzymes suggests that PHA synthase, the enzyme responsible for polymerizing 3-hydroxybutyric CoA, controls the molecular weight of PHB produced in vivo.
