The right and appropriate system of receiving and transferring goods is needed by the company. In the process of receiving and transferring goods from the central warehouse to the branch warehouse at PDAM Tirta Kerta Raharja, Tangerang Regency, which is currently done manually is still ineffective and inaccurate because the Head of Subdivision uses receipt documents, namely PPBP and mutation of goods, namely MPPW in the form of paper as a submission media. The Head of Subdivision enters the data of receipt and mutation of goods manually and requires a relatively long time because at the time of demand for the transfer of goods the Head of Subdivision must check the inventory of goods in the central warehouse first. Therefore, it is necessary to hold a design of information systems for the receipt and transfer of goods from the central warehouse to a web-based branch warehouse that is already database so that it is more effective, efficient and accurate. With the web-based system of receiving and transferring goods that are already datatabed, it can facilitate the Head of Subdivision in inputing data on the receipt and transfer of goods and control of stock inventory so that the Sub Head of Subdivision can do it periodically to make it more effective, efficient and accurate. The method of data collection is done by observing, interviewing and studying literature from various previous studies, while the system analysis method uses the Waterfall method which aims to solve a problem and uses design methods with visual modeling that is object oriented with UML while programming using PHP and MySQL as a database.

Customer Satisfaction And Loyalty

Transformation of the banking sector has led to today's banks providing a complete service - financial service both on the domestic and international level. The focus of their business is the client whose loyalty depends on the operations of the bank. The aim is to indicate that there is a direct link between the quality of the banking product and the service that affects the client's satisfaction and loyalty, which directly affects the bank's business and its competitive advantage in the financial market. The paper gives a theoretical and practical overview of the quality of service, satisfaction and loyalty of clients, and the performance of the bank, which depends on clients. In the theoretical part, the concept of a client, its significance and specifics related to its influence on the bank's business, through its satisfaction and loyalty to the bank, is defined. The empirical part deals with the analysis of customer satisfaction and loyalty towards banking products and services in Montenegro and how much the quality of banking services has an impact on the satisfaction and loyalty of the customer. The analysis of the factual situation will be carried out, the conclusions will be presented and recommendations made for improvement of the quality of the service, which will contribute to the greater satisfaction of the clients, and therefore the loyalty to the particular bank. All of this is directly related to the possibility of achieving the competitive advantage of banks within the banking sector where a particular bank operates.

The emergence of what we call today the World Wide Web, the WWW, or simply the Web, dates back to 1989 when Tim Berners-Lee proposed a hypertext system to manage information overload at CERN, Switzerland (Berners-Lee, 1989). This article outlines how his approaches evolved into the Web that drives today’s information society and explores its full potentials still ahead. The formerly known wide-area hypertext information retrieval initiative quickly gained momentum due to the fast adoption of graphical browser programs and standardization activities of the World Wide Web Consortium (W3C). In the beginning, based only on the standards of HTML, HTTP, and URL, the sites provided by the Web were static, meaning the information stayed unchanged until the original publisher decided for an update. For a long time, the WWW, today referred to as Web 1.0, was understood as a technical mean to publish information to a vast audience across time and space. Data was kept locally and Web sites were only occasionally updated by uploading files from the client to the Web server. Application software was limited to local desktops and operated only on local data. With the advent of dynamic concepts on server-side (script languages like hypertext preprocessor (PHP) or Perl and Web applications with JSP or ASP) and client-side (e.g., JavaScript), the WWW became more dynamic. Server-side content management systems (CMS) allowed editing Web sites via the browser during run-time. These systems interact with multiple users through PHP-interfaces that push information into server-side databases (e.g., mySQL) which again feed Web sites with content. Thus, the Web became accessible and editable not only for programmers and “techies” but also for the common user. Yet, technological limitations such as slow Internet connections, consumer-unfriendly Internet rates, and poor multimedia support still inhibited a mass-usage of the Web. It needed broad-band Internet access, flat rates, and digitalized media processing to catch on.

In the research on interdisciplinarity (RID), measures for evaluating the interdisciplinarity of scientific entities (e.g., papers, authors, journals or research areas) have been proposed for a long time. The author interdisciplinarity is very different from the other types of interdisciplinarity because of the complex interpersonal relationships between the connected authors. However, previous work has failed to uncover the distinctiveness of author interdisciplinarity and has regarded it as equivalent to other types of interdisciplinarity. In this work, an extended Rao–Stirling diversity measure is proposed, which incorporates the co-author network and a network similarity measure to specifically evaluate the author interdisciplinarity. Moreover, betweenness centrality is used for improving network similarity measure, because of its intrinsic advantage of expressing how an entity loads on different factors in a network, which is highly in line with the characteristic of interdisciplinarity. An experiment on the papers about Public Administration in the Web of Science is conducted; based on the final results, a deeper investigation is performed into by typical authors. The work proposes a novel idea for measuring author interdisciplinarity, which can promote the study of interdisicplinarity measuring in RID.

New Phase

Final repositories for spent nuclear fuel are approaching implementation. A prerequisite for these advancements is that it has been shown that the repository can be constructed and operated in practice in such a way that safety can be assured both during operation and over very long time scales. The success rests on decades of structured and objective-driven research and development. A key element of the research strategy has been to ensure adequate in-house competence and expertise. Also, openness and international cooperation are essential. Workable procedures for data qualification, version control as well as internal and external peer review have gained importance. When the programmes now enter a new phase of construction and operation new challenges will arise. Even if the implementing organisations would need to keep a core competence on post closure safety assessment international cooperation will be even more important on developing, sharing and managing the knowledge needed.

The paper deals with blended education in turbomachinery and fluid dynamics courses in Finland. The teaching methodology of these courses has been developed to comply with the new challenges of the education in technology. Presently six of the courses in the curriculum are following the schemes explained in this presentation. The courses are studied in the last year of the Bachelor level and in the Masters level quantifying from 2 to 4 ECTS credits. Students get all the material from the teaching platform in the web, which can be accessed freely anytime and practically from anywhere. Before attending the teaching events, the students go through the study material, perform several exercises and take a quiz, which can give them extra points for the exam tally. The contact teaching of the course is divided into four Learning Sessions of four hours. The first half is reserved to deepen the acquired knowledge, and performed in a way to attract a more interactive atmosphere. In the second half the students are divided to groups, where they solve more difficult study exercises compared to those they already have trained on. As the students are expected to study with the material of blended learning in advance, the percentage of the contact hours has to be lowered in comparison to the traditional teaching in order to maintain a balance with the credits in the course. However, with the acquired knowledge, the students are more interactive with the teachers and the teaching becomes more efficient. The students have given positive feedback on the courses. The instructors have found that the blended learning is not necessary an easier task, although there are less contact hours with the student. The efficiency of teaching has increased and the teaching is more rewarding. Both the students and the teachers found that blended education suited best for student groups around 10 students.
