In this paper, we compared the user experience according to utilize parallax scrolling technique in web site. For this purpose, we divided subjects into two groups. The subjects of Group1 were given to use web site interface with Parallax scrolling and the Group2 were given to use web site interface with non Parallax scrolling. Then, All Subjects answered the questionnaire of user experience. User experience were evaluated by four entries as Novelty, Esthetics, Usage of Satisfaction, Cheerfulness. Consequently. As a result, the web site interface with Parallax scrolling showed significantly higher score of Novelty, Esthetics, Cheerfulness than the web site interface with non-Parallax scrolling. In this study. we proved that using the parallax scrolling technique in web site interface improves the overall user experience, and suggested to apply as a way to advance the attention and persistency on creating a web site.

This study was conducted to develop user interface design guidelines for those who design education software products (web sites or CD-ROM titles). To establish this guideline scheme, international standards, commercial design guidelines, and research papers were surveyed. Especially, ISO 9241 was referred as a basic model of a guideline scheme. First, the research group developed draft guidelines. After that, education software developers, designers, and a user group reviewed the draft and the draft was revised with their commentations. Five components were selected as a primary class of guideline scheme: general principle, dialogue design, user guidance, visual interface, and information presentation. Each component was divided several components as a secondary class. Finally, 45 items were selected as user interface design guidelines for the education software design.

This paper is proposed structure which it sees currently the problem point which it follows in the independent space for work which the members who do a same work from the environment which is to fall tile at distance, therefore the MPLS based VPN necessary to follow, it forms the small-scale group which is closed again with the CUG(Closed User Group) it will be able to own jointly information to present a structure, the individual small-scale groups are closed from outside and the group members are the CUG authentication Process for the security maintenance the model which is possible.

비대면 거래 활성화로 증권사 간 영업점포 규모나 거래 비용면의 차별성은 줄어들고 증권거래 시스템에 대한 중요성이 높아졌다. 특히 개인 투자자들이 많이 사용하는 모바일 트레이딩 시스템의 거래 비중 증가와 코로나19 이후 개인 투자자의 증가로 모바일 트레이딩 시스템은 더욱 중요해졌다. 하지만 모바일 트레이딩 시스템에 관한 사용성 연구는 문헌조사나 설문조사방법으로 진행되어 사용자 중심의 사용성 연구는 부족하다. 이에 본 연구에서는 사용자 중심의 사용성 속성을 알아보기 위해 사용자의 경험적 인식을 찾아내는 레퍼토리 그리드 기법을 사용하였다. 사용자 관점의 모바일 트레이딩 시스템 사용성 속성을 도출하고 사용자 그룹과 개발자 그룹간의 빈도와 중요도 측면에서 사용성 속성 차이를 확인하였다.

The energy of the building is influenced by the user 's activity due to the population, society, and economic characteristics of the building user. In order to obtain accurate energy information, the difference in the amount of energy consumption by the activities and characteristics of building users should be identified. The purpose of the study is to identify the difference in the amount of energy consumption by the user's activities in the same building, and to analyse the relationship between user's activities and demographic, social and economic characteristics. For research, energy simulation is performed based on actual user activity schedule. The results of the simulation were clustered by using K-Means clustering, a machine learning technique. As a result, four types of users were derived based on the amount of energy consumption. The more energy used in a cluster, the lower the user's income level and older. The longer a user's indoor activity times, the higher the energy use, and these activities relate to the user's characteristics. There is more than twice the difference between the group that uses the least energy consumption and the group that uses the most energy consumption.

Purpose The purpose of this study is to investigate the factors that affect the user satisfaction and continuous use intention of the improved ATCIS in the Korean Army. Design/methodology/approach Based on the various theories in relation to IT continuance, user satisfaction was identified as the main factor with regard to the continuous use intention of the improved ATCIS. In addition, computer self-efficacy, education-training, and system quality were hypothesized as antecedent variables to user satisfaction, and information security stress was set as a moderating variable for these relationships. Findings Survey results show that computer self-efficacy, education and training, and system quality had a positive effect on user satisfaction, and information security stress was found to moderate these relationships. The effects of computer self-efficacy and education-training on user satisfaction were higher in the group with low information security stress. However, the relationship between system quality and user satisfaction was higher in the group with high information security stress. User satisfaction is found to have a positive effect on the continuous use intention even with habit considered as a control variable.

The purpose of this paper is to identify optimal designs of server port connections between two server system for 200-300 user group. Given 3 empirical models as user and port parallel server types under some conditions of 100 Mbps and optimal CPU temperature suggested by Lee and Kim(2005), our results are shown; port parallel model was optimal when traffic processing times measured, and 250 traffics was jumping point as a critical point in our cases.

Software piracy is widespread throughout the world. It has negative effects on the software industry and the intellectual property market. Despite various deterrent policies, the phenomenon has been getting severe. The current study investigated the antecedents of software piracy attitudes and intention. In order to identify factors and their relationship, a research model for illegal piracy behavior was developed and empirically examined through a path analysis using structural equation model. Also, this study employed a multiple group structural equation model to investigate differences in structural weights across PC software user group and smartphone application user group. It was revealed that perceived benefit, habit, social factor, self-efficacy had positive effect on attitude toward software piracy, whereas perceived risk had a decreasing influence on attitude. Relationships between piracy attitudes and intentions were significant as well. Furthermore, the cross validation between two groups showed the path coefficients of habit to attitude and attitude to intention were significantly different. Implications for research and practice are discussed.
