  • Lithium gel electrolytes based on a mixed polymer matrix consisting of poly(vinylidenefluoride-hexafluoropropylene) (PVDF-HFP) and cyanoresin type M (CRM) were prepared using an in situ blending process. The CRM used in this study was a copolymer of cyanoethyl pullulan and cyanoethyl poly(vinyl alcohol) (PVA) with a mole ratio of 1:1. The mixed plasticizer was ethylene carbonate (EC) and propylene carbonate (PC) with a volume ratio of 1:1. In this study, the presence of PVDF in the electrolytes helps to form a dimensionally stable film over a broad composition range, and decreases the viscosity. In addition, it provides better rheological properties that are suitable for the extrusion of thin films. However, the presence of HFP has a positive effect on generating an amorphous domain in a crystalline PVDF structure. The ionic conductivity of the polymer electrolytes was investigated in the range 298-333 K. The introduction of CRM into the PVDF-HFP/$LiPF_6$, complex produced a PVDF-HFP/CRM/$LiPF_6$ complex with a higher ionic conductivity and improved thermal stability and dynamic mechanical properties than a simple PVDF-HFP/$LiPF_6$, complex.

  • As the numbers of Internet users have grown dramatically in recent years due to increased use of mobile devices, businesses using internet are also expanding rapidly. Internet marketing has the advantage of expanding business without any constraint of time and space using the global network which connects tens of thousands of world's computers and mobile devices. In a way of utilizing internet marketing, the present study examines the applicability of Customer Relationship Management (CRM) to the domestic professional baseball industry in Korea. The study focuses on the issue of whether the intangible value of customer satisfaction can create higher profits. We combine both inductive and conductive methods for this study. First, we carry out a random survey of baseball spectators and find that customers are willing to pay more when their satisfaction level is improved. Next, we recognize satisfaction factors that are considered as important by customers through literature survey. Then we use Decision Tree to find which satisfaction factors are most important to each clustered customer group. Finally we estimate how much they would pay more when the most important satisfaction factor improves by each customer group. Therefore, this study demonstrates that CRM implementation to one-to-one internet marketing can improve the profitability of baseball industry. The major contribution of the present study is to show that the introduction of CRM can be used as a profit-generating strategy in various industries for future internet marketing.

  • 고객관계관리(customer relationship management: 이하 CRM)는 고객에 대한 정보를 수집하고 수집된 정보를 효과적으로 활용하여 신규고객획득, 우수고객 유지, 고객가치 증진, 잠재고객 활성화, 평생 고객화의 순환을 통하여 고객을 적극적으로 관리하고 유지하며 고객의 가치를 극대화시키기 위한 기업 마케팅 전략의 일환이다. 특히 경쟁 환경이 급변하고 치열해 짐에 따라 기업의 수익 극대화를 위한 고객가치 증대 및 고객과의 관계 형성을 위한 CRM활동 중 고객의 이탈방지를 통한 유지관리의 중요성이 점차 커지고 있으며, 이러한 움직임은 고객 세분화를 통한 이탈고객 관리분석으로 주로 금융시장에서 다루어져왔다. 한편, 금융시장뿐만 아니라 모든 사업 분야에서 고객 유지 및 이탈방지를 위한 분석의 필요성은 높아지고 있다. 그 이유는 자사가 보유하고 있는 고객의 특성을 파악함으로써 기존의 고객을 효과적으로 유지·관리하여 고객이탈을 막는 것이 고객관리에서 점차 그 중요성을 더하기 때문이다. 그러나 아직까지 필요성만 대두될 뿐 어떠한 속성을 보유하고 있는 고객이 쉽게 이탈하는지를 판별할 수 있는 이탈고객에 대한 체계적인 연구가 진행되지 않았다는데 한계점이 있다. 이에 본 연구에서는 TV 홈쇼핑사의 실제 고객자료를 통하여 고객의 유지 및 이탈방지를 위한 CRM전개방안, 이탈고객과 유지고객간의 인구통계적 속성 및 거래 행동의 특성 차이를 분석, 이탈에 미치는 영향력이 높은 변수를 밝혀내고 이탈고객예측 모형을 통하여 개별고객의 이탈확률을 예측하고자 했다. 더 나아가 실증 분석 결과를 바탕으로 이탈예측고객을 대상으로 고객 이탈을 방지하고 거래유지 및 활성화를 위한 CRM전개 방안을 도출, 이를 바탕으로 TV 홈쇼핑사가 수립해야할 마케팅 전략을 제시한다.

  • $TiO_2$-Ni inverse catalysts were prepared using atomic layer deposition (ALD) process and catalytic $CO_2$ reforming of methane (CRM) reaction over catalysts (either bare Ni or $TiO_2$ coated-Ni particles) were performed using a continuous flow reactor at $800^{\circ}C$. $TiO_2$-Ni inverse catalyst showed higher catalytic reactivity at initial stage of CRM reactions at $800^{\circ}C$ comparing to bare Ni catalysts. Moreover, catalytic activity of $TiO_2$/Ni catalyst was kept high during 13 hrs of the CRM reactions at $800^{\circ}C$, whereas deactivation of bare Ni surface was started within 1hr under same conditions. The results of surface analysis using SEM, XPS, and Raman showed that deposition of graphitic carbon was effectively suppressed in a presence of $TiO_2$ nanoparticles on Ni surface, thereby improving catalytic reactivity and stability of $TiO_2$/Ni catalytic systems. We suggest that utilizing decoration effect of metal catalyst with oxide nanoaprticles is of great potential to develop metal-based catalysts with high stability and reactivity.

  • Background: We aimed to establish robust histoprognostic predictors on residual rectal cancer after preoperative chemoradiotherapy (CRT). Methods: Analyzing known histoprognostic factors in 146 patients with residual disease allows associations with patient outcome to be evaluated. Results: The median follow-up time was 77.8 months, during which 59 patients (40.4%) experienced recurrence and 41 (28.1%) died of rectal cancer. On univariate analysis, residual tumor size, ypT category, ypN category, ypTNM stage, downstage, tumor regression grade, lymphatic invasion, perineural invasion, venous invasion, and circumferential resection margin (CRM) were significantly associated with recurrence free survival (RFS) or/and cancer-specific survival (CSS) (all p<0.005). On multivariate analysis, higher ypTNM stage and CRM positivity were identified as independent prognostic factors for RFS (ypTNM stage, p=0.024; CRM positivity, p<0.001) and CSS (p=0.022, p=0.017, respectively). Furthermore, CRM positivity was an independent predictor of reduced RFS and CSS, irrespective of subgrouping according to downstage (non-downstage, p<0.001 and p<0.001; downstage, p=0.002 and p=0.002) or lymph node metastasis (non-metastasis, p<0.001 and p=0.001; metastasis, p<0.001 and p<0.001). Conclusion: CRM status may be as powerful as ypTNM stage as a prognostic indicator for patient outcome in patients with residual rectal cancer after preoperative CRT.

  • Environment-friendly agriculture has not only the simple purpose producing foods but also the key roles of conserving rural environments, landscapes and sustainable land uses. In addition, environment-friendly agricultural areas and their landscapes are important factors representing uniqueness of rural areas. For these reasons, this study investigates the landscapes formed through environment-friendly agriculture and evaluates the economic values of the landscapes using CRM(contingent ranking method) which has been known as one of the practical methods in the field of environmental economics. Based upon a scenario that government introduces the ratio of environment-friendly agriculture to evaluate economic values, a survey was performed with 1,088 of rural residents throughout the country. The results of this study indicate that the economic value for conservation and maintenance of environment-friendly agriculture landscapes is 480 won per household/month/1% environment-friendly agriculture, and this can be converted into 829 hundred million won per 1% environment-friendly agriculture nationally.

  • 실세계의 많은 시스템들은 동적이며 복잡한 현상으로 이뤄져 있다. 이러한 특징의 시스템을 이해하는 방법의 하나로 시스템에 대한 모델을 세우고 분석하는 방법이 있다. 본 연구에서는 동적시스템에서 발생되는 시계열데이터들의 분석을 위한 방법론을 제시한다. 시스템 모델링을 통해 사용자들에게 1:1의 맞춤정보를 제공하기 위한 CRM(고객관계관리) 인터페이스를 제안한다. 실험에서 실제의 시계열데이터를 통하여 군집화 하는 과정에서는 유사기반의 방식보다 모델기반 방식이 더 나은 군집화 결과를 산출하였고 각 군집의 모델을 생성한 후 모델을 통하여 일정기간 시계열 데이터를 생산하여 이를 실제 곡선의 운동양태와 비교 분석하였다. 주가와 같은 실제 시계열데이터에 제안된 방법을 적용하여 모델로 생산된 데이터가 실제의 데이터와 비교하여 얼마나 근사한지를 확인하여 제안된 방법의 유효성을 검증하였다.
