Amid the Covid pandemic surge last year, customers and businesses started embracing digital transactions. Digital banking, as an answer to the cash-less-contact-less way of doing financial transactions, was highly convenient during the pandemic, especially in the Philippines. This position examines the Gen Y and Gen Z in the Philippine case and its willingness to encourage digitalization of the financial sector. This study aimed at evaluating the intention to use digital banking services using the factors (1) ease of use; (2) perceived usefulness; (3) perceived risk; (4) trust; (5) convenience. A total of 226 respondents were selected by random sampling method and linear regression was used to analyse the collected data. Analysis of the results show that the components (1) perceived ease of use; (2) perceived usefulness; (3) perceived risk; (4) trust; (5) convenience had a significant effect on intention to use digital banking while the demographics - gender, age, monthly income, and educational attainment do not have any significance on the intention to use digital banking. The relevance of the study can be used for marketing and financial strategies to increase the intention to use digital banking and to contribute to the enhancement of technology acceptance concerning digital banking.

In these days, oil cost is about 70 US dollars, but, on the day of July. 2008, it was over 140 US dollars. This coast led fisheries industry to increasement of operating coast and made public problems such as non-operation of fishing boats and lockout of the related factories. Thus this paper studies the way to use cheap fuel in order to reduce the fuel cost. Normally fishing boat use Marine Gas Oil. this study explains to use blended oil such as MF 60, 100, 180 instead of MGO.

The current study investigates major factors which influence the acceptance of mobile internet services based on the theoretical backgrounds of the technology acceptance model(TAM) and the flow theory. This research extended the Davis' TAM model(1989) by including the flow concept as another major factor towards the intention to use the mobile device in order to explain the acceptance of divers mobile services. According to the marketing studies(Ghani & Desphande, 1994; Novak, Hoffman & Yung, 2000), flow is regarded a psychological state in which one is absorbed in something he or she is doing, and is known to be widely adopted in explaining one's acceptance in the area of game, sports, and even hobby. This study developed a research model to explain the use of mobile services employing usefulness, ease of use and flow as major research variables, and collected 221 survey responses from the high school students who had experiences with such mobile services as game and audio file download. The results of the current research indicates that usefulness and flow influence the intension to use mobile services, but the effect of ease of use did not appear significant to the intention to use. It was also found that flow affects both usefulness and ease of use, and then ease of use next influences usefulness.

본 연구는 최근 들어 사용이 꾸준히 증가하고 있는 스마트폰 다이어트/운동 앱에 주목하면서, 채널확장이론 (channel expansion theory)과 기술수용모델 (technology acceptance model)에 기반하여, 세 가지 선행요인-인터넷 정보이용 효능감, 스마트폰 이용 효능감, 그리고 인터넷 정보에 대한 신뢰도 -이 다이어트/운동 앱에 대한 태도 및 수용의도에 미치는 영향에 대해 분석했다. 경로분석 결과에 따르면, 인터넷 정보이용 효능감과 스마트폰 이용 효능감은 다이어트/운동 앱에 대한 인지된 사용 용이성 (PEOU)에 정적인 영향을 미치고, 인터넷 정보에 대한 신뢰도는 해당 앱에 대한 인지된 유용성 (PU)에 정적인 영향을 미치는 것으로 나타났다. 이에 더해, 인터넷 정보이용 효능감과 인터넷 정보에 대한 신뢰도가 다이어트/운동 앱에 대한 인지된 유용성에 미치는 영향은 성별에 따라 유의미한 차이를 보였다.

Several companies have migrated their existing monolithic web applications to microservice architectures. Consequently, research on the identification of microservices from monolithic web applications has been conducted. Meanwhile, the use-case model plays a crucial role in outlining the system's functionalities at a high level of abstraction, and studies have been conducted to identify microservices by utilizing this model. However, previous studies on microservice identification utilizing use-cases did not consider the components executed in the presentation layer. Unlike existing approaches, this paper proposes a technique that considers all three layers of web applications (presentation, business logic, and data access layers). Initially, the components used in the three layers of a web application are extracted by executing all the scenarios that constitute its use-cases. Thereafter, the usage rate of each component is determined for each use-case and the component is allocated to the use-case with the highest rate. Then, each use-case is realized as a microservice. To verify the proposed approach, microservice identification is performed using open-source web applications.

This paper examines user's loyalty to social network sites (SNS) from switching costs (SC) incurred by both technology and social factors. We propose a research model specifying that the perceived values of resources of the factors affect the SC and the SC determine user's loyalty. Empirical results show that technology variables of ease of use and privacy controllability, and social variables such as network size, usefulness of SNS activities, and awareness of network status have significant effect on SC. In particular, ease of use is negatively associated with SC. Since it is shown that in overall the impact of social factors is stronger than that of technology factors, we can interpret that technological superiority itself does not lead to the success of SNS. Contributions of this paper are: 1) application of SC in SNS research from the resource based perspective, which can be used for developing strategies of sustainable SNS, and 2) provision of different perspective toward the variable of ease of use, which has been considered an important factor of technology acceptance.
