고객 기반의 산업에서 고객 Retention은 기업의 경쟁력이라 할 수 있으며, 고객 Retention을 높이는 것은 기업의 경쟁력을 높이는 것이라 할 수 있다. 따라서, 미래 휴면 고객을 잘 예측하여 관리하는 것은 기업의 경쟁력을 높이는데 무엇보다 중요하다. 왜냐하면, 신규 고객을 유치하는데 필요한 비용이 기존 고객을 Lock-in 시키는데 드는 비용 보다 많은 것으로 알려져 있기 때문이다. 특히, 수 많은 카드사가 존재하는 국내 카드 산업의 휴면 카드를 관리하고자 정부에서 휴면 카드 자동 해지 제도를 도입하고 있으며, 카드 산업에서 휴면 고객을 관리하는 것이 무엇보다 중요한 과제로 떠오르고 있다. 본 연구에서는 카드 산업에서 휴면 고객을 예측하기 위해 Recurrent Neural Network (RNN)방법론을 사용하였으며, RNN방법론 중에서 긴 시간을 효율적으로 학습할 수 있는 Long-Short Term Memory (LSTM)을 활용하였다. 또한, 통합기술수용이론 (UTAUT)을 입각하여 카드 산업에서 휴면 고객을 예측하는데 필요한 변수를 재정의하였다. 그 결과 안정된 모형의 정확도와 F-1 score를 얻을 수 있었으며, Hit-Ratio를 통하여 모형의 안정된 결과를 입증하였다. 기존 연구에서 지적된 통합기술수용이론 (UTAUT)에서 발생 될 수 있는 인구통계학적 정보의 조절 효과도 발생 되지 않은 것을 보였으며, 이로 인해 통합기술수용이론(UTAUT)를 이용한 변수 선정 모형에서 LSTM을 이용한 휴면 고객 예측 모형은 편향되지 않고 안정된 결과를 가져다 줄 수 있다는 것을 입증하였다.

The paper begin by examining shipbuilding in the context of competitiveness, specification and cost-effectiveness before considering the impact of safety requirements in the its operations. The basis of the safety case approach is then given, and its application to shipbuilding is illustrated by an example based on the use of staging in ship construction. The key conclusion is that the safety case approach provides the management with a technique for treating potential hazards in shipbuilding so that their risks can be kept within an acceptable level.

Green building technology has the potential a competitiveness. Reflecting this situation, the renewable energy market is growing rapidly. And, this field became value-added field in construction industry. In this study perform to prioritize the value improvements of green building technologies. To do this, first, we will extract potential development field through literature and case studies. Next, we will built a hierarchy structure based on the economic efficiency, technical skill, and policy. Third, we decide to prioritize between the items by performing AHP analysis.

The current downturn of BIPV sector has an enormous potential to rebound and expand into the PV sector for construction market in the foreseeable future. Solar technology has already gained a significant market due to lack of natural resources in the Korean domestic market. Given the technical infrastructure of state-of-the-art fusion technology, the competitiveness of software-driven BIPV market in the world can be ver attractive and have the potential to develop as a key national technology. To do this, from the viewpoint of complexity, technical R&D, national political aspect, social aspect, economic aspect and institutional support systems need to be parallelly formulated. A dedicated BIPV sector has not yet been established, especially policy and institutional framework have very crucial impact on the establishment of BIPV sector.

In this research, we have developed a model that can explain the potential customer's needs for the potable Internet service, a concept with 'QoS guaranteed lower-price high speed mobile Internet service. Based on the developed model, we have also derived some empirical implications for the business firms interest in the potable Internet market. The developed model is incorporating a survey result, answering of potential customer's attitude for the portable Internet service, from the subscribers to the Internet service, wireless LAN service, and mobile Internet service. As a result, we have found that a very innovative group, such as wireless LAN users and 20's age group using mobile Internet service, could be the most attractive market segment. Moreover, the aspects of the service coverage and the price competitiveness at the service launching stage could be the most critical success factors for the portable Internet service.

Sodium-cooled fast reactor is considered in France as a potential candidate for a prototype of 4th generation system to be built by 2020. A detailed working program has been launched recently to identify by 2012 the potential improvement tracks for later industrial development of these reactors. The goals for innovation are first identified: Progress of the safety with a special attention to severe accidents risk minimization and mitigation (defense in depth approach); Economic competitiveness of the system mainly by reducing the capital cost, the investment risks by enhancing in service inspection and repair capacities, and raising the availability; Sustainability with fissile material management while reducing the proliferation risk; capacity for long-lived waste transmutation.

One of the major current challenges to nuclear energy lies in its competitiveness. To stay competitive the industry needs to reduce maintenance and fuel cycle costs, while enhancing safety features. Extended burnup is one of the methods applied to meet these objectives However, there are a number of potential fuel failure causes related to increased burnup, as follows: l) Corrosion of zirconium alloy cladding and the water chemistry parameters that enhance corrosion; 2) Dimensional changes of zirconium alloy components, 3) Stresses that challenge zirconium alloy ductility and the effect of hydrogen (H) pickup and redistribution as it affects ductility, 4) Fuel rod internal pressure, 5) Pellet-cladding interactions (PCI) and 6) pellet-cladding mechanical interactions (PCMI). This paper discusses current and potential failure mechanisms of these failure mechanisms.

Purpose: At a time when the distribution industry is dominated by capital and technology, win-win growth among businesses groups (BGs) in wholesale market is becoming a social issue. Therefore, through analysis of market growth, market concentration (MC) and market power (MP), we want to identify the structure of the wholesale market and the competitiveness of the BGs in terms of market share (MS), sales-profit ratio (SPR), and labor productivity (LP) to explore the possibility of win-win growth. Market situation: Wholesale and Retail sales ratio (W/S) continues to increase, which also means inefficiency in distribution channels or opportunities in wholesale markets. Wholesale sales have grown 8.3 percent annually over the past 15 years, while the number of companies and workers has declined since 2017, which is why some restructuring is believed to begin in the wholesale industry. In terms of MC and MP, the growth potential of SBG can be found in FCB, ARM, FBT and CME BTs. Methodology and data: Through ANOVA and Regression Analysis, the 2015 Economic Census Data of KOSTAT was analyzed. Results: The results of ANOVA show that statistically significant SBG has a larger MS than LBG. The SPR was not different among BGs. LP is higher for LBG than for other BGs. Regression results show that the employment weight (EW) and the company size (SC) have positive effects on the MS, but the company weight (CW) and employment size (SE) have negative effects. In the case of SPR, the CW is positive and the EW is negative. In addition, LP appears to be more positive as SC in the BGs is larger. Conclusions: Although there is sufficient potential for SBG in the wholesale market, there is a problem that needs to increase LP. Therefore, the SBG needs to restructure in terms of number of companies and SC to improve the efficiency of employment. In terms of MC and MP, the SBG looks for possibilities in FCB, ARM, FBT and CME BTs. In addition, SBG that seeks higher returns with human services rather than simple sales is found to be competitive in the HHG, MES and CME BTs.
