Opis:
A distance education system is designed based on fuzzy inference, where visualized atmosphere information is shared by all learners in a virtual classroom. It provides high aspirations, low isolated feeling, low stress, and high affinity to learners, and offers learner’s psychological information, individual difference information, and hints of system improvement to the system manager. The effect of visualized atmosphere information in the learner’s psychological states is confirmed by T score of POMS test for 15 graduate students using CAI contents, and comparison experiment with traditional distance education. The proposal of atmosphere information presentation of virtual classroom provides a first step in establishing Education Academy beyond Space Time (EAST).

Opis:
The Mediterranean Sea has seen an increase of ports hosting cruise ships during the first fifteen years of the 21st century. The increase in cruise ship presence in Mediterranean ports is associated with the dynamism of cruise traffic in recent years, with an average annual growth of 7.45% for cruise passengers worldwide during the period of 1990-2015. Cruise traffic is a maritime business that is primarily composed of two elements, maritime affairs and tourism. This article focuses on the maritime component. With the growth of the cruise industry, cruise lines have been forced to seek new ports to meet demand in an attempt to create differentiated products based on the ports that compose the itinerary. The itinerary system of cruise traffic makes the cruise ports depend on one another to design an itinerary. This feature results in both complex geographic relationships in the design of a cruise itinerary and complex competitive/cooperative relationships between ports. The aim of this article is to present the hierarchic picture of a sample of 29 cruise ports in the Western Mediterranean region during the period of 2000-2015. To achieve this goal, a port size classification is proposed and a shift-share analysis at the inter- and intra-group size level is applied. Moreover, concentration measures are used to determine the changes in the levels of market concentration. Furthermore, a dynamic model is proposed to determine the competitive or cooperative relationships between cruise ports. The proposed model is applied to the largest ports with data from the 2001-2015 period.

Opis:
The first part of this article presents the modeling of the long-channel bulk MOSFET as a particular case of the SOI MOSFET. The second part reviews compares and scrutinizes various methods to extract the threshold voltage, the effective channel and the individual values of drain and source resistances. These are important device parameters for modeling and circuit simulation.

Opis:
In this paper, we describe a previously unknown species of the glirid Eliomys from the Late Miocene and Early Pliocene Cabriel, Alcoy and Granada basins of southeastern Spain. Eliomys yevesi sp. nov. is characterized by its relative small size, narrow lingual wall and common presence of two centrolophs in the upper molars, and well-developed centrol-ophids in the lower molars. The new species is the probable ancestor of E. intermedius, which in turn represents the ancestor of the extant E. quercinus. According to its morphologic and biometric features, the origin of E. yevesi sp. nov. is likely to be found in some population of E. truci from the Late Miocene. Based on these affinities, we propose the lineage E. truci-E. yevesi sp. nov.-E. intermedius-E. quercinus, in which there is a trend towards the development of centrolophs, as well as the reduction of accessory crests.

Opis:
We investigated the short-term effects of spent coffee grounds on the physical properties of two Mediterranean agricultural soils (Calcisol and Luvisol). The in vitro assay was performed with two spent coffee grounds doses (60 and 240 Mg ha-1), two incubation times (30 and 60 days) and two modalities: with and without lettuce seedlings (Lactuca sativa var. longifolia). Spent coffee grounds addition increased water retention at -33 and -1500 kPa, and decreased bulk density and plant-available water content. With spent coffee grounds, the percentage of macroaggregates increased, the percentage of meso- and microaggregates decreased and the structural stability of all types of aggregates increased. The stereomicroscopy images showed that: the structural aggregates were rounded, the porosity increased by 316%, the structure was ordered into smaller aggregates, the incorporation of spent coffee grounds particles could occur in intraped cracks and spent coffee grounds particles could act as a binding agent. Scanning electron microscopy also showed that spent coffee grounds particles interacted with mineral particles and integrated into soil structure; moreover, fungal hyphae also developed on many spent coffee grounds particles. If spent coffee grounds effects are compared with those described in the literature for other organic amendments, the same trend was observed in most of the soil physical properties although with a different intensity, principally with regard to structural stability.

Opis:
Here we report a new Early Pleistocene record of agamid lizards (Agamidae indet.) from the Spanish locality of Quibas (ca. 1.3–1.0 Ma), which represents the latest evidence of the family in Western Europe. Up to now, the family Agamidae was considered to have disappeared in this region at 1.8 Ma. This new record implies the survival of agamid lizards for a large part of the Early Pleistocene in the southernmost Iberian Peninsula, probably because of favourable climatic and environmental conditions. Consequently, the formerly detected Pliocene / Pleistocene boundary is no longer recognisable in the evolution of the herpetological assemblages in Western Europe.
