OBJECTIVE To establish the prevalence of menstrual-related problems among university students. MATERIALS AND METHODS A questionnaire regarding gynecological, bleeding and family history was sent by electronic mail (e-mail) to all female students attending University College London (UCL). RESULTS A total of 767 students aged 18-39 years replied; 71% had a regular menstrual cycle. One in thre...

Public-Key Infrastructures are considered the basis of the protocols and tools needed to guarantee the security demanded for new Internet applications like electronic commerce, government-citizen relationships and digital distribution. This paper introduces a new infrastructure design, Cert’eM, a key management and certification system that is based on the structure of the electronic mail servi...

ATENA (A Telephone and Electronic-mail NAme guide system) is a distributed name guide system designed for developing a prototype of new E-mail system. The prototype system is based on CCITT X.500 standard. The goal of ATENA is to provide users with efficient name guide services and to experimentally find ways for constructing integrated network database system. We have provided a model of devel...

Most organizations have formal and informal elements. Formal structures are usually documented in organizational charts showing chain of command, levels of authority, and personnel resources. The actual effectiveness of the organization or specific individuals may actually depend on informal structures and internal communication networks. These are by definition personality-dependent and may pr...

Email overload is a growing problem for many users in the workplace [1]. Users often have trouble retrieving messages for use later or in remembering to reply or to act on a particular message. There are two causes. The first is due to the problems associated with maintenance and retrieval in a semantic hierarchical structure. The second is due to current email systems are designed around the a...

Telepathology is based on the sharing of medical images coming from the microscope, and comprises different applications: intra-operative telediagnosis, second opinion teleconsultation, reference case archives, remote data and image processing, quality assessment. Since the Internet is available worldwide, it can be of interest to define which of these tasks can be performed by means of some te...

This paper reports and analyses the views of long-standing active members of standards setting working groups in the field of electronic communications. We focus in particular on their experiences of, and attitudes towards, user participation in standardisation.

The goal of the analysis was to identify the distinct patterns of communication behavior...

The success of an organization depends on rapid, reliable, and direct communications within the organization and with the outside world. To determine if electronic mail (e-mail) provides a competitive benefit, a sample of 99 management-level participants in 41 companies responded to a survey that assessed their intraorganizational (internal) and interorganizational (external) uses of e-mail. Th...

In the framework of the Stochastic Formulation of Quantum Mechanics we derive non-stationary states for a class of time-dependent potentials. The wave-packets follow a classical motion with constant dispersion. The new states de ne a possible extension of the harmonic-oscillator coherent states. As an explicit application we study a sestic oscillator potential. Electronic Mail: demartino@vaxsa....
