The ISP 98 is developed by the American Institute of International Banking Law & Practice in 1998. The ISP98 are also published as ICC Publication No. 590. A detailed commentary on the rules("The Official Commentary on the International Standby Practice") has been written by Professor James E. Byrnes. Presently there is no compelling reason to revise the rules themselves even if ten years is passed since the issuance of ISP98. Insteadthe American Institute of International Banking Law & Practice will provide Model Forms in the early 2009. Special features of the ISP 98 are as the following. Firstly, the ISP 98 is copyrighted by the Institute of International Banking Law and Practice, Inc., and published by the International Chamber of Commerce. Secondly, the ISP 98 differs from UCP in style and approach because it must receive acceptance not only from bankers and merchants, but also from a broader range of those actively involved in standby law and practice corporate treasurees and credit manager, rating agencies, government agencies and regulators, and indenture trustees as well as their counsel. Because standbys are often intended to be available in the event of disputes or applicant insovency, their texts are subject to a degree of scrutiny not encountered in the commercial letter of credit context. Thirdly, the ISP 98 supplement the UCP if the UCP dose not have the relative rule. Lastly, the ISP 98 has the official commentary. In addition, several provision of the ISP 98 would surprise the commercial parties and/or are rather peculiar, while some of them display a certain bias in favor of the banks.

온라인 뱅킹 서비스는 금전과 관련된 업무를 처리함으로 정보교환에 있어서 안전한 보안이 제공되어야 한다. 현재 안전한 전자 금융 거래 서비스를 위해 공인인증서와 비밀번호, 보안카드, 일회용 비밀번호생성기(OTP) 와 같이 여러 가지 사용자 인증 방법이 존재한다. 특히 보안카드는 금융거래를 진행함에 있어서 모든 비밀정보를 포함하는 가장 중요한 비밀 매체이고 한 번 노출이 되고 나면 보안카드로써의 기능을 상실할 뿐 아니라 공격자는 획득하기 가장 어려운 비밀정보를 가지게 되므로 보다 높은 확률로 공격을 성공할 수 있다. 본 논문에서는 물리적인 보안카드가 가지는 비밀정보를 다른 채널에 분할하여 저장하는 기법을 통해 정보 유출의 위험성을 줄이는 방안을 제시한다. 제안하는 멀티채널 보안카드는 표시되는 비밀 정보의 양을 줄이고, 동적으로 생성하는 방법을 이용하여 비밀 정보 노출의 취약성을 줄이고 피싱 공격을 예방하는 기능을 가진다.

The study aims to explore key dimensions of service quality of E-Retailing of Islamic banks in the Kingdom of Saudi Arabia. The convenience sample size consists of 373 respondents who regularly use online Islamic banking facilities in Saudi Arabia was used. For measuring the consumers' perspective, a four-factor E-SERVQUAL scale; namely efficiency, system availability, fulfillment, and privacy was used. Exploratory Factor Analysis and Confirmatory Factor Analysis are used to test the model fitness. Structural equation modelling is utilized to determine the impact of E-service quality dimensions on customers' satisfaction. The results of the study reveal that 1) reliability as a dimension of E-retailing of Islamic banks made a significant impact on customers' overall satisfaction; 2) there is a positive significant relationship between responsiveness and customers' overall satisfaction. One unit increased in responsive leads to 0.763 unit increases in the overall satisfaction of the customer; and 3) ease of use is the most important dimensions of service quality of E-retailing of Islamic banks. One unit increases in Security/ Privacy leads to 0.473 unit increases in overall satisfaction. There is a positive impact of good E-service on customers' satisfaction, but it does not override unsatisfactory performance in other areas.

This paper presents a strong designated verifiable signcryption scheme, in which a message is signcrypted by a signcryptor and only a specific receiver, who called a "designated verifier", verifies it using his own secret key. The scheme is secure, as an adversary can not verify the signature even if the secret key of the signer is compromised or leaked. The security of the proposed scheme lies in the complexity of solving two computationally hard problems, namely, the Discrete Logarithm Problem (DLP) and the Integer Factorization Problem (IFP). The security analysis of the scheme has been done and it is proved that, the proposed scheme can withstand an adaptive chosen ciphertext attack. This scheme can be very useful in organizations where there is a need to send confidential documents to a specific recipient. This scheme can also be applicable to real life scenarios, such as, e-commerce applications, e-banking and e-voting.

Studies related to Electronic Word-of-Mouth (eWOM) show that the acceptance of eWOM information is an important factor in customer purchase decisions. When consumers accept eWOM information, they tend to use that information in considering before making purchase decisions. In Viet Nam, there are few studies about eWOM information, especially on the acceptance of eWOM information. Research is conducted to test the influence of consumers on the perception of the senders' identity to the acceptance of online reviews (a kind of eWOM) in Viet Nam - a case study in Ho Chi Minh City. Using adjustment techniques, inspecting the scales and a theoretical model represent the relationship among the influential factors. The research is based on a sample of 522 consumers who use the Internet to search for product reviews before buying and used Structural Equation Modeling (SEM) to test the relationships among the variables. The research results show that the scales of the variables: Message Quality, Source Credibility, Perceived Message Usefulness, Perceived Senders' Identity, Perceived Message Credibility, Message Acceptance attain the validity and reliability in the research. The research contributes to the understanding of the determinants that influence the acceptance of eWOM information, which are informational factors, and factors related to consumer skepticism.

The ability of smartphones to facilitate various services like mobile banking, e-commerce and mobile payments has made them part of consumers' lives. Conjoint analysis (CA) is a marketing research approach used to assess how consumers' preferences for products or services develop. The potential applications of CA are numerous in consumer electronics, banking and insurance services, job selection and workplace loyalty, consumer packaged goods, and travel and tourism. Choice-Based Conjoint (CBC) analysis is the most commonly used CA approach in marketing research. The purpose of this study is to utilise CBC analysis to investigate the relative importance of smartphone attributes that influence consumer smartphone preference. An experiment was designed using Sawtooth CBC Software. 326 students attempted the online survey. Utility values were derived by Hierarchical Bayes (HB) estimation and used to explain consumers' smartphone preferences. All the six attributes used for the study were found to significantly influence smartphone preference. Smartphone brand was the most important, followed by the price, camera, RAM, battery life, and storage. This study is one of the first to use Sawtooth CBC analysis to assess consumer smartphone preference based on the six attributes. We provide implications for the development of new smartphones based on attributes.

The aim of the present study is to analyze the financial performance of converted commercial bank from non-banking financial institution through a case study of Bangladesh Commerce Bank Limited as sample organization. It is observed that the bank is able to achieve a stable growth rate in total deposits, total loans and advances, and net income after tax during the period of 2015-2019. Researchers also calculated some ratio analysis and noticed that the financial position of Bangladesh Commerce Bank Limited was not so strong because bank's ROA, ROE, NIM and other ratios were below standard. Researchers used secondary data that were examined by using descriptive statistical tools and panel data regression model. Result shows that Bangladesh Commerce Bank has satisfactory operating efficiency, assets management efficiency, and gives loans to customers. In addition, the present study has tested some hypotheses regarding net income after tax, ROA and ROE with total assets, total loans, total deposits and interest income. These hypotheses have been accepted, which means there is no significant influence of the independent variable on the dependent variable. The study suggests that Bangladesh Commerce Bank Limited had the opportunities to make their financial position stronger by utilizing their good financial position and management efficiencies.

최근의 세계금융산업(世界金融産業)은 이종금융업무간(異種金融業務間)의 통합(統合)(겸업(兼業))과 동시에 이와는 반대로 개별업무(個別業務)의 분할현상(分割現象)을 동시에 같이 경험하고 있는데, 본고(本稿)는 이러한 금융산업조직(金融産業組織)의 내생적(內生的) 재편현상(再編現象)을 체계적으로 설명할 수 있는 금융산업조직이론(金融産業組織理論)을 모색하는 데 그 목적이 있다. 기존의 전문화(專門化)와 겸업화이론(兼業化理論)을 통합한 잠정적 분석체계는 대체로 다음과 같은 시사점을 주고 있다. 첫째로, 독자적으로는 규모(規模)의 경제(經濟)가 강하고 여타 업무와는 범위(範圍)의 비경제하(非經濟下)에 있거나 범위(範圍)의 경제(經濟)가 약한 업무는 기존 업무세트에서 분할(分割) 전문화(專門化)될 것이다. 둘째로, 여타업무와는 범위(範圍)의 경제(經濟)가 강하면서, 독자적으로는 규모(規模)의 비경제하(非經濟下)에 있거나 혹은 규모(規模)의 경제(經濟)가 약한 업무는 겸업(兼業)될 것이다. 셋째로, 자유금융하(自由金融下)의 경쟁금융산업균형(競爭金融産業均衡)은 겸업기업(兼業企業)과 전업기업(專業企業)이 공존하는 혼합균형(混合均衡)이 될 것이다. 넷째로, 금융산업조직(金融産業組織)의 국가별 차이는 금융시장(金融市場) 및 수요규모(需要規模)의 차이에 의해 결정되며, 최근 진행되고 있는 금융(金融)의 세계화(世界化) 국제화(國際化)는 각국이 직면하게 될 금융시장(金融市場)의 규모를 균등화시킴으로써 장기적으로 각국 금융산업조직(金融産業組織)의 동질화(同質化)를 촉진시킬 것이다. 다섯째로, 금융제도(金融制度)에 대한 인위적 규제가 없다면 겸업주의(兼業主義) 은행제도(銀行制度)는 금융시장(金融市場)의 규모(規模)가 상대적으로 작은 경제에서, 전업주의(專業主義) 은행제도(銀行制度)는 금융시장의 규모가 상대적으로 큰 경제에서 주로 관찰되게 될 것이다. 본고(本稿)는 이러한 시사점들을 응용하여 주요국에 있어서의 전업주의(專業主義)와 겸업주의(兼業主義) 은행제도(銀行制度)의 역사적 변천과정을 각국 금융시장규모(金融市場規模)의 변천과정에 의해 설명하고, 현재 구조변화(構造變化)를 경험하고 있는 세계각국(世界各國) 금융산업조직(金融産業組織)은 장기적으로 구조가 동질화(同質化)되면서 혼합균형상태(混合均衡狀態)로 이행해 나갈 것으로 전망하고 있다.
