Purpose: During and after Covid-19 pandemic, technology has emerged as a key factor in supporting the recovery of the economy and the rise of living standards. This study examines seven factors affecting the intention of food delivery apps usage, which include Performance Expectancy, Effort Expectancy, Social Influence, Hedonic Motivation, Price Value, and Habit, and how much influence they have on the customers' behavioral continuance of food delivery apps after Covid-19 Pandemic. Research methodology: This research is a quantitative descriptive research with 473 qualified respondents from 550 respondents collected. Besides using the UTAUT2 model (Venkatesh et al., 2012), Information Quality was added to give a better explanation for the consumers' intention towards continuance behavior using food delivery apps. The collected data is then processed using SPSS 22.0. Results: Habit factors and Information Quality factors have significant positive effects on promoting food delivery apps usage intention, which in turn influences continuance behavior. In addition, Habit factors and Information Quality factors together have an effect of 48.57% on Behavioral Intention. Conclusion: The result proves that positive habits and food information quality can increase the usage intention towards the behavioral continuance of consumers. Higher usage frequency can be improved by increasing these two factors.

As the easy payment service is popularized and the competition in the service market is fierce, research on factors affecting users' continuous use of the easy payment service is becoming increasingly important. However, in the existing studies, the discussion of the continuous intention to use the consumer's simple payment service has not been sufficiently conducted. Existing research remains on the way of listing technology and consumer characteristics. To bridge this research gap, this study aims to integrate and modify ECM and UTAUT to consider factors influencing the continuous use of easy payment services. The user's expectations and the confirmation were considered as important factors to decide. For empirical analysis, a survey was conducted for 236 users who had experience with domestic easy payment service. As a result, it was verified that confirmation, performance expectancy, effort expectancy, social influence, and habit in regard to easy payment services are important for continuous use intention. Through this study, it is expected that the consumer's technology acceptance mechanism on the continuous use of simple payment will be grasped in more detail to develop academic discussions in the field. Implications from the results as well as limitations of the study are presented.

In the previous studies, some genetic polymorphisms in the human mitochondrial DNA have been associated with athletic performance in several populations. To investigate the relationship between mitochondrial DNA 5178A/C polymorphism and athletic performance in Korean population, blood samples were collected from 100 male Korean elite athletes and 64 sedentary controls. There was no significant difference in allele frequency of mitochondrial DNA 5178A/C polymorphism between two groups (P > 0.05). However, 5178A allele frequency in Korean population was very higher than those in other populations studied. Because it has been reported that this genetic polymorphisms is associated with longevity, further study will be needed to clarify the relationship between this genetic polymorphism and life expectancy of Korean population.

Rail car axles are very important parts for safety of passengers and structural integrity of vehicles. The axles are supported by bearings. To seal grease lubricating the bearings of freight cars, an oil seal has been developed. The developed oil seal is composed of an inner plate, an outer plate and a seal rubber. The friction between axle and housing with the developed oil seal is very low. The seals are designed for a minimum life expectancy of 800,000 kilometers service. In this study, an accelerated durability tests according to AAR Specification M-934-82 were carried out. In addition, various performance tests according to KS B 2804 were conducted.

To endorse the reliability and durability of the solar photovoltaic (PV) device several tests were conducted before exposing to the outdoor field in a non-ideal condition. The PV module has high probability that intend to perform adequately for 30 years under operating conditions. To evaluate the long term performance of the PV module in diversified terrestrial conditions, one should use the outdoor performance data. However, no one wants to wait for 25 years to determine the module reliability. The accelerating stress tests performing in the laboratory by mimicking different field conditions are thus important to understand the performance of a PV module. In this review, we will discuss briefly about different accelerating stress types, levels and prioritization that are used to evaluate the PV module reliability and durability before using them in real field.

Purpose - This paper attempts to derive effective performance-reward strategies for SMEs to raise the valence for their employees while using their relatively limited resources, which is one of the primary concerns raised by SME CEOs. Research design, data, and methodology - This paper draws on the four question items such as the financial/direct factors, the financial/indirect factors, the non-financial/direct factors and the non-financial/indirect performance-reward factors to shed light on the most important factors and aspects that need improving, using the AHP and IPA. Results - The overall findings on the SMEs' performance-reward factors of interest here are indicative of the need for rectifying their performance-reward systems. Conclusions - SMEs' performance-reward factors of interest here are indicative of the need for rectifying their performance-reward systems. In particular, despite the fact that SMEs can hardly offer high wages or bonuses as large enterprises do, the expectancy theory suggests it is better to reward employees as per a valid common system, while the equity theory underscores the need to maintain and reinforce the fairness in distribution, procedures and interactions.

본 연구는 쇼핑몰과 쇼핑몰에 입점한 테넌트를 연구의 대상으로 하고 있다. 쇼핑몰의 발전과 성장에 비해서 지금까지의 학문적 관심은 매우 제한적이었다. 본 연구에서는 기대-불일치 패러다임의 주요 변수인 기대, 성과, 불일치, 만족 및 재방문 의도를 쇼핑몰과 테넌트의 맥락에서 점검하고 있다. 특히 쇼핑몰과 테넌트간의 기대, 성과, 불일치, 만족 및 재방문 의도의 상호 영향을 중심으로 연구모형을 제시하였다. 가설은 기대불일치 관련변인을 쇼핑몰과 테넌트에 각각 적용하는 것에서 시작하여 쇼핑몰의 변수가 테넌트의 변수에 영향을 미치는 경우와 테넌트의 변수가 쇼핑몰의 변수에 영향을 미치는 경우로 확장하였다. 영향관계의 방향을 명확히 알 수 있는 경우와 이를 탐색해야 하는 부분으로 구분하여 고객의 쇼핑몰과 테넌트에 대한 상호 영향을 확인하였다. 461명의 몰인터셉트 서베이 결과 연구모형은 대체로 기대한 가설을 지지하는 것으로 나타났다. 방향성을 확인하는 가설에서는 테넌트에 대한 불일치와 만족이 쇼핑몰에 대한 불일치와 만족에 미치는 영향이 반대의 방향보다 유의적인 것으로 나타났으며 쇼핑몰에 대한 만족은 테넌트에 대한 재방문 의도에 미치는 유의적인 영향을 미치는 것으로 확인되있다.

Electronic Records Management System (ERMS) is a computer program or set of applications that is utilized for keeping up to date records along with their storage. ERMS has been extensively utilized for enhancing the performance of academic institutions. The system assists in the planning and decision-making processes, which in turn enhances the competencies. However, although ERMS is significant in supporting the process of decision-making, the majority of organizations have failed to take an initiative to implement it, taking into account that are some implementing it without an appropriate framework, and thus resulted in the practice which does not meet the accepted standard. Therefore, this study identifies the factors influencing the adoption of ERMS among employees of HLI in Yemen and the role of such adoption in the decision-making process, using the Unified Theory of Acceptance and Use of Technology (UTAUT) along with Technology, Organization and Environment (TOE) as the underpinning theories. The study conducts a cross-sectional survey with a questionnaire as the technique for data collection, distributed to 364 participants in various Yemeni public Higher Learning Institutions (HLI). Using AMOS as a statistical method, the findings revealed there are significant and positive relationships between technology factors (effort expectancy, performance expectancy, IT infrastructure and security), organizational factors (top management support, financial support, training, and policy),environmental factors (competitiveness pressure, facilitating conditions and trust) and behavioral intention to adopt ERMS, which in return has a significant relationship with the process of decision-making in HLI. The study also presents a variety of theoretical and empirical contributions that enrich the body of knowledge in the field of technology adoption and the electronic record's domain.
