Telemarketing has been used in finance due to the reduction of offline channels. In order to select telemarketing target customers, various machine learning techniques have emerged to maximize the effect of minimum cost. However, there are problems that the class imbalance, which the number of marketing success customers is smaller than the number of failed customers, and the recall rate is lower than accuracy. In this paper, we propose a method that solve the imbalanced class problem and increase the recall rate to improve the efficiency. The hybrid sampling method is applied to balance the data in the class, and the stacked deep network is applied to improve the recall and precision as well as the accuracy. The proposed method is applied to actual bank telemarketing data. As a result of the comparison experiment, the accuracy, the recall, and the precision is improved higher than that of the conventional methods.

In the transaction of credits, banks must examine the presentation to determine, on the basis of the documents alone, whether or not the documents appear on their face to constitute a complying presentation. And bank shall each have a maximum of five banking days following the day of presentation to determine if a presentation is complying. This period does not depend on any upcoming expiry date or last day for presentation. Data in a document, when read in context with the credit, the document itself and international standard banking practice, need not be identical to, but must not conflict with, data in i) that document; ii) any other stipulated document; or iii) the credit. When a bank determines that a presentation is complying, it must honour or negotiate. But, when a bank determine that a presentation does not comply, it may refuse to honour or negotiate. When a bank decides to refuse to honour or negotiate, it must give a single notice to that effect to the presenter. That notice must be given by telecommunication or, if that is not possible, by other expeditious means no later than the close of the fifth banking day following the day of presentation.

Purpose - This paper aims to study the competition that occurs in the Islamic Banking industry and to analyze the variables that affect the total revenue of Islamic Banking in Indonesia. Research Design, Data and Methodology - This study observed 10Islamic banks for the period 2010-2013. The annual data are taken from Direktori Perbankan Indonesia, published by Bank Indonesia, and annual report of the observed banks. In analyzing data, Panzar Rosse Approach was applied to analyze the type of Islamic Bank Market and Panel Regression Model for the estimated co-efficients has been used in the Panzar Rosse Approach. Results - Estimation model shows that all the banking cost elements such as the price of capital, unit price of labor, and unit prices of funds have significant positive correlation to Revenue as a dependent variable. The estimated value of H-statistic for the period 2010-2013 is 0.69. It can be interpreted that Islamic banking market in Indonesia shows monopolistic competition. Price of capital and funds has statistically significant effect on Bank's Revenue. Conclusions - The study revealed that the Islamic banking market competition in Indonesia is monopolistic and the major contribution to the H-statistic comes from mainly price of funds.

The levee and bridge pier in estuary of the Hangang River are exposed in a dangerous condition due to bank erosion and local scouring occurred since the summer season in 2011. At first, it is presumed that the high sandbar formed in river channel of the study area was an important element in the occurrence of bank erosion and local scouring. It can be presumed that the record-breaking depth of freezing due to cold wave for the long term during the winter season between 2010 and 2011 as well as the heavy intensive rainfall of 2011 had a decisive effect on the first damage of A section. The second damage of B section mainly occurred around the bridge pier constructed on the high water channel before it was washed away during the winter season between 2011 and 2012. It is considered that the second damage was caused by ice formation and ice floes.

This paper presents phenomena of vibration and noise due to acoustic resonance in tube bank of a large fossil power plant. The phenomena of acoustic resonance may arise when the vortex shedding frequency coincides with the acoustic natural frequency. In this system dominant frequency of vibration and noise was 37.5Hz. The $3^{rd}$ acoustic natural frequency calculated was 37.2 Hz. When the difference of vortex shedding frequency and acoustic natural frequency is within ${\pm}20%$, acoustic resonance could occur. If system is the state of acoustic resonance, vibration and noise become large. In order to prevent acoustic resonance, anti-noise baffle should be installed in the tube bank. In the case of installing baffle, we should consider the number of baffle and the effect of acoustic mode due to baffle extension length. To do this, we did acoustic mode analysis. After installing anti-noise baffle, acoustic resonance was disappeared and vibration magnitude and noise level was reduced dramatically.

The paper examines the role of the informal sector on innovation activities of urban formal manufacturing enterprises in India. It provides empirical evidence on firm-level linkages between formal and informal sectors by using the World Bank Enterprise Survey, 2013-14 and the Innovation Follow-up survey, 2014. Primarily, the paper aims to examine the effect of informal sector competition on innovation in urban formal manufacturing enterprises in India. Secondly, the paper analyses the mediation effect of informal sector competition on innovations in the urban manufacturing enterprises. It determines the direct and indirect influence of business regulations and constraints on innovation outcomes through the mediation effect of informal sector competition by using the SEM "Structural Equation Modeling" guidelines. The econometric results show that informal sector competition has a negative effect on the introduction of product innovations while industry-level informal sector competition has a positive effect on product innovation through the local knowledge spillovers from the informal to the formal sector. However, the informal sector competition was found to have no significant effect on the probability of introducing process innovations. Further, the results show the inhibitive role of informal sector competition on innovation in urban formal manufacturing enterprises is more severe for firms with heavy regulatory burdens and is relatively weakened in firms with resource constraints. This suggests that the informal sector plays an important role in the NIS (National Innovation System) in India.

Sophorae Flos (SF), a composite of flowers and flower-buds of Sophora japonica, has long been used in traditional Korean and Chinese medicines for the treatment of hemostasis and inflammation. In this study, we investigated anti-inflammatory effect of four EtOH extracts at the difference in blooming stages of flowers on LPS-induced inflammation in RAW264.7 cells. We classified the flowers of Sophora japonica with SF-1 (length of flower is shorter than calyx), SF-2 (length of calyx is shorter than flower), SF-3 (full bloom), and SF-4 (not blooming at all). We examined HPLC analysis, whether quercetin and rutin are major component of these Sophorae Flos extracts or not. As a result, SF-1 contained quercetin, but the others did not. In addition, quercetin, SF-1, and SF-4 act on the suppression of pro-inflammatory mediators including inducible nitric oxide synthase (iNOS), cyclooxygenase (COX)-2, nitric oxide (NO), prostaglandin E2 ($PGE_2$) against lipopolysaccharide (LPS)-induced activation in RAW264.7 cells. Of these, SF-1 showed the best anti-inflammatory effect. These results suggest that Sophorae Flos with the highest content of quercetin would be used for the treatment of various inflammation diseases.

본 연구는 국제무역에 참여하고 있는 우리나라의 기업들을 대상으로 수출입이 기업의 노동수요에 미치는 영향을 살펴보았다. 통계청의 기업활동조사 데이터를 이용하여 2006년부터 2014년까지 제조업 24개 업종에 속해 있는 기업들의 수출입이 노동수요에 미치는 영향을 시스템 GMM 방법을 사용하여 분석하였다. 분석 결과, 생산성이 높은 기업에서는 수출이 늘어나면서 생산 확대를 위한 노동수요가 창출되는 효과가 나타난 반면 생산성이 낮은 기업에서는 이러한 효과가 유의하게 나타나지 않았다. 그러나 기업이 오프쇼어링을 이용하여 국내업무를 해외로 재배치한 경우, 수출이 유발하는 노동수요 증가 효과가 축소되는 것으로 분석되었다. 한편, 수입증대는 기업의 노동수요를 감소시키는 것으로 나타나는 데, 이는 수입제품이 노동을 대체하는 효과 때문인 것으로 보인다. 반면 기업이 오프쇼어링을 이용하는 경우, 생산 효율성 증대로 수입의 노동수요 감소효과가 완화되는 것으로 나타났다. 본 연구의 결과는 수출입이 기업의 고용에 미치는 영향은 기업의 생산성 및 글로벌 아웃소싱 참여 여부에 따라 달라질 수 있음을 시사한다.
