디스크에서는 데이터가 변경되면 해당 영역에 겹쳐 쓰기를 수행하나 플래시 메모리에서는 겹쳐 쓰기가 수행되지 않아 데이터가 변경될 때 새로운 영역에 데이터를 갱신한다. 따라서 이전의 데이터는 쓸모없는 데이터가 되기 때문에 가비지 컬렉션을 통해 지움 연산을 수행하여 새로운 영역을 확보하게 된다. 지움(erase) 연산을 수행할 수 있는 회수가 플래시 메모리의 특성에 의해 일정 회수로 제한을 받게 되므로 플래시 메모리의 모든 블록은 고르게 쓰여 지고 지워져야 한다. 본 논문은 지역성을 가지는 접근에서 wear-leveling을 개선하기 위한 방법으로 hot 데이터와 cold 데이터를 서로 다른 뱅크에 저장하고 시간이 흐름에 따라 일정주기로 cold 뱅크와 hot 뱅크를 교환하는 CB-MB(Cost Benefit between Multi Bank) 방법을 제안하고 성능을 평가하였다. CB-MB는 uniform한 작업부하에 대해서는 다른 방법들과 유사한 성능을 보이는 반면 접근 지역성을 가지는 작업부하에 대해서는 상대적으로 월등한 성능을 제공하는 것으로 분석되었다.

NPF Islamic banking needs to be resolved because it affects banking performance in terms of income and the quality of its productive assets. This study aims to solve problems of non-performing financing and assess and analyze whether the implementation of the Islamic Humanity model can reduce the problem of financing at Bank Syariah Mandiri Indonesia. The study uses qualitative method with Miles and Huberman approach for analizing data through four steps which are; (a) data collection (b) data reduction (c) data display, and (d) conclusion drawing/verification. The results of the study found non performing financing can be reduced with using a new approach namely the Islamic Humanity Approach, which is an interaction between several aspects, namely (a) spiritual aspects, (b) economic aspects, (c) social aspects, and (d) justice aspects. The Islamic humanity model carried out in problem-solving activities at Bank Syariah Mandiri Indonesia includes a friendly approach, communication and deliberation in a family, respect for people, empathy, the concept of justice, and the concept of prayer. Islamic humanity approach shows success in reducing non-performing financing. The research concluded Islamic humanity as a new approach to reduce non-performing financing at Bank Syariah Mandiri Indonesia and it can be implemented to all Islamic banking in Indonesia.

Biobank Impact Factor (BIF), which is a very effective criterion to evaluate the activity of biobanks, can be estimated by the citation information of biobanks from scientific papers. We have developed a program, ManBIF, to investigate the citation information from PDF files in the literature. The program manages a dictionary for expressions to represent biobanks and their resources, mines the citation information by converting PDF files to text files and searching with a dictionary, and produces a statistical report file. It can be used as an important tool by biobanks.

The reviews of the balance sheet of commercial banks showed that loan item constitutes the largest portion of bank's assets. Although the sector has highest rate of profit, it possesses the greatest risk. Identifying factors that can contribute in lifting-up the loan repayment rate of customers of Hawassa district commercial bank is the major goal of this study. A sample of 183 customers who took loan from October, 2005 to April, 2012 was taken from the bank record. Kaplan-Meier estimation method and univariate Cox proportional hazard model were applied to identify factors affecting bank loan repayment rate. The result from Kaplan-Meier survival estimation revealed that the loan repayment rate is significantly related with loan type, and previous loan experience, educational level and mode of repayment. The log-rank test indicates that the survival probability of loan customers is not statistically different in repaying the loan among groups classified by sex. Moreover, the univariate Cox proportional hazard model result portrayed that educational level, having previous loan experience, mode of repayment, collateral type and purpose of loan are significantly related with loan repayment rate of customers commercial bank. Hence, banks should design loan strategies giving special emphasis on the significant factors while they are giving loans to their customers.

This research aims to analyze transglobal leadership which has an impact on bank sustainability with militancy and organizational culture variables as mediating variables. In addition, to evaluate militancy, cultural organizations exist to encourage bank sustainability. This is an explanatory research conducted using a quantitative approach in the form of a survey. The population of this study includes all Heads of Regional Offices and Head of Branch Offices of PT. Bank Rakyat Indonesia is spread across Sumatra, Java, Kalimantan, Sulawesi, Bali and Jayapura. This study uses a research instrument in the form of a questionnaire that has been tested for validity and reliability and secondary data. Quantitative data analysis was performed in the form of Structural Equation Modeling (SEM) analysis based on Partial Least Square (PLS) to answer the research hypothesis. The results show a significant and positive relationship between transglobal and militancy leadership, transglobal leadership with innovation culture, militancy with innovation culture, militancy with bank sustainability and innovation culture with bank sustainability. The novelty of this research lies in the use of militancy and innovation culture as intervening variables in the correlation between transglobal leadership and bank sustainability. The militancy variable is the new variable to be checked.

The implications of bank-specific risks and macroeconomic risks on the growth, profitability, and stability of Islamic and conventional banks are examined and compared in this article. The study also investigates whether corporate governance mitigates the effects of both bank-specific and macroeconomic risks on Islamic and conventional banks' development, profitability, and stability. For the period 2007-2019, we examined a panel data set of 22 banks in Pakistan, including both Islamic and conventional banks. We discovered considerable evidence that both bank-specific risks and macroeconomic risks have negative effects on the growth, profitability, and stability of Pakistani banks using a dynamic panel data estimator, the two-step Generalized Method of Moments (GMM) approach. Furthermore, the findings show that bank-specific and macroeconomic risks have different consequences in both types of banking. The impacts of liquidity risk, operational risk, capital risk, inflation risk, and exchange rate risk are higher for Islamic banks than for conventional banks. Conventional banks, on the other hand, are more vulnerable to credit risk and interest rate risk. Finally, the findings show that good corporate governance reduces the negative consequences of both categories of risks on bank development, profitability, and stability. This is true for Islamic and conventional banks alike.

A fixed rate speech coder based on the filter bank and the non-uniform sampling technique is proposed. The non-uniform sampling is achieved by the detection of inflection points (IPs). A speech block is band passed by the filter bank, and the subband signals are processed by the IP detector, and the detected IP patterns are compared with entries of the IP database. For each subband signal, the address of the closest member of the database and the energy of the IP pattern are transmitted through channel. In the receiver, the decoder recovers the subband signals using the received addresses and the energy information, and reconstructs the speech via the filter bank summation. As results, the coder shows fixed data rate contrary to the existing speech coders based on the non-uniform sampling. Through computer simulation, the usefulness of the proposed technique is confirmed. The signal-to-noise ratio (SNR) performance of the proposed method is comparable to that of the uniform sampled pulse code modulation (PCM) below 20 kbps data rate.

본 연구는 국내 모바일 뱅킹 애플리케이션에 대한 이용자 리뷰 데이터에 텍스트 마이닝 기법을 적용하여 중요도-만족도 분석을 시도하고, 개선의 우선순위를 도출하는 것을 목적으로 한다. 분석에는 구글 플레이스토어에서 국내 시중은행(국민은행, 신한은행, 우리은행, 하나은행), 지역은행(경남은행, 부산은행), 인터넷 은행(카카오뱅크, 케이뱅크, 토스)의 모바일 뱅킹 애플리케이션에 대한 이용자 리뷰 데이터를 활용하였으며, 주요 속성 도출 및 각 속성에 대한 중요도와 만족도 측정을 위해 토픽 모델링, 빈도분석 및 감성분석을 진행하였다. 분석 결과 '인증서비스', '기능 개선', '로그인', '속도/연결성', '시스템/업데이트' 그리고 '뱅킹서비스'가 이용자들이 모바일 뱅킹 애플리케이션을 사용할 때 느끼는 중요도가 상대적으로 높은 속성임에도 불구하고 그 만족도가 평균 수준에 미치지 못해 개선이 시급한 속성으로 나타났다.
