In this article, we will present the rich linguistic heritage of the Croatian language and our attempts to ensure its preservation and presentation to the general public by means of the "Retro-digitization and Interpretation of Croatian Grammar Books before Illyrism ‒ RETROGRAM" project. There is a long tradition of grammatical description in the history of the Croatian language. The first grammar book of the Croatian language was written at the beginning of the 17th century and the first grammar book written in Croatian was compiled in the middle of the 17th century. In later years, when literary and linguistic activity were transferred from the Dalmatian area to the northern and eastern part of Croatia, the Latin model for the description of the Croatian language was still present, even though German was also used. There were a large number of grammars written up to the second half of the 19th century, which are considered pre-standard Croatian grammars. They are the subject of research within the project "Pre-standard Croatian Grammars" at the Institute of Croatian Language and Linguistics. This research proposal "Retro-digitization and Interpretation of Croatian Grammar Books before Illyrism" aims to create a model for the retro-digitization of the chosen eight Pre-standard Croatian Grammars (written from the 17th until the 19th century). The retro-digitization of Croatian grammar books implies the transfer of printed media to computer-readable and searchable text. It also includes a multilevel mark-up of transcribed or translated grammar text. The next step of the project is the creation of a Web Portal of Pre-standard Croatian Grammars, on which both the facsimiles and the digitized text of the grammars will be presented. Our aim is to present to the wider and international public the attainments of the Croatian language and linguistics as an important part of Croatian culture in general.

In existing literature, Semantic Web portals (SWPs) are sometimes known as semantic portals or semantically enhanced portals. It is the next generation Web portal which publishes contents and information readable both by machines and humans. A SWP has all the generic functionalities of a Web portal but is developed using semantic Web technologies. However, it has several enhanced capabilities such as semantics- based search, browse, navigation, automation processes, extraction, and integration of information (Lausen, Stollberg, Hernandez, Ding, Han & Fensel, 2004; Perry & Stiles, 2004). To date the only available resources on SWPs are isolated published Web resources and research or working papers. There is a need to pool these resources together in a coherent way so as to provide the readers a comprehensive idea of what SWPs are, and how they could be built, and these will be supported by some appropriate examples. Additionally, this article will provide useful Web links for more extensive as well as intensive reading on the subject.

Elementary students use the Web to find information, but can encounter problems with keyword searching. An alternative is to choose terms from a taxonomy (subject directory), but students may then encounter problems in locating a term within the taxonomy. This paper reports on a comparative analysis of a conventional, hierarchically displayed taxonomy with a display of the same taxonomy using information visualization techniques. The evaluations were undertaken by students from grade-six (11 to 12 years’ old) and are part of a larger study on the application of information visualization techniques to interfaces targeted at children.Les élèves du primaire utilisent le Web pour trouver de l'information, mais peuvent avoir des difficultés avec la recherche par mots-clés. Une possibilité serait de choisir des termes à partir d'une taxonomie (liste de sujets), mais dans ces circonstances, ils pourraient avoir de la difficulté à localiser le terme voulu. Cet article présente l'analyse comparative d'une taxonomie hiérarchique conventionnelle et de la même taxonomie présentée en utilisant des techniques de visualisation de l'information. Les évaluations ont été effectuées par des élèves de 6e année (11 et 12 ans) et font partie intégrante d'une étude plus vaste sur l'application de techniques de visualisation de l'information dans la conception d'interfaces ciblant les enfants.

Introduction. A subject directory plays an important role in a Web portal and it helps users effectively navigate the portal. This study examines a subject directory system related to Mental Health in the MedlinePlus portal and provides suggestions of optimisation to enhance the subject directory system. Method. A mixed research method combining social network analysis and inferential statistics was applied. Analysis. A structural and a semantic social network were built regarding the selected health topics related to mental health in the MedlinePlus portal. The two networks were compared and the outcomes were evaluated by domain experts. Results. Among the ninety-nine collected health topics related to mental health, three themes were identified through the visualisation analysis regarding grouped health topics. Patterns and characteristics of each theme group were discussed. As a result, fifty-five bidirectional and twenty-three unidirectional edges were identified and recommended to be added to the corresponding health topic pages. The recommended results indicate that the subject directory of specific mental health related topics is well constructed, while health consumer groups related topics might need more improvements. The optimised subject directory has significantly stronger semantic connection, and the results of the recommendations are consistent with the evaluation outcome of two domain experts. Conclusions. The findings of this study can provide ideas of optimising and enhancing the subject directory system to the public health portal creators and health professionals, and benefit health consumers for seeking health information online. The methodologies applied in this study may provide a novel way to investigate and enhance subject directories in general.

The Subject

THE germ of that which follows came into being many years ago in the days of my youth as a university instructor and assistant professor. It was generated by the then quite outspoken attitude of colleagues in the “exact sciences”; the sciences of which the subject-matter can be exactly weighed and measured and the force of its movements mathematically demonstrated. They assured us that the study of languages and literature had little or nothing scientific about it because: “It had no domain of concrete fact in which to work.” Ergo, the scientific spirit was theirs by a stroke of “efficacious grace” as it were. Ours was at best only a kind of “sufficient grace,” pleasant and even necessary to have, but which could, by no means ensure a reception among the elected.

Orbit Computation

In this paper an orbit computation program for artificial satellites is presented. This program is operational and it has already been used to compute the orbits of several satellites.After an introductory discussion on the subject of artificial satellite orbit computations, the features of this program are thoroughly explained. In order to achieve the representation of the orbital elements over short intervals of time a drag-free perturbation theory coupled with a differential correction procedure is used, while the long range behavior is obtained empirically. The empirical treatment of the non-gravitational effects upon the satellite motion seems to be very satisfactory. Numerical analysis procedures supporting this treatment and experience gained in using our program are also objects of discussion.

Rule: I'd like at this point to bring up the subject of cables and wireways around the telescope. We've touched upon this twice during previous sessions: the cable wrap up problem, the communications problem, and data multiplexing problem. I think we'll ask Bill Baustian if he will give us a brief run down on what the electrical run problems are, besides doubling the system every year.

Biologic Factors

The Mesozoic-Cenozoic coral Order Scleractinia has been suggested to have originated or evolved (1) by direct descent from the Paleozoic Order Rugosa or (2) by the development of a skeleton in members of one of the anemone groups that probably have existed throughout Phanerozoic time. In spite of much work on the subject, advocates of the direct descent hypothesis have failed to find convincing evidence of this relationship. Critical points are:(1) Rugosan septal insertion is serial; Scleractinian insertion is cyclic; no intermediate stages have been demonstrated. Apparent intermediates are Scleractinia having bilateral cyclic insertion or teratological Rugosa.(2) There is convincing evidence that the skeletons of many Rugosa were calcitic and none are known to be or to have been aragonitic. In contrast, the skeletons of all living Scleractinia are aragonitic and there is evidence that fossil Scleractinia were aragonitic also. The mineralogic difference is almost certainly due to intrinsic biologic factors.(3) No early Triassic corals of either group are known. This fact is not compelling (by itself) but is important in connection with points 1 and 2, because, given direct descent, both changes took place during this only stage in the history of the two groups in which there are no known corals.

The growth of Ag films deposited on various substrate materials such as MoS2, mica, graphite, and MgO has been investigated extensively using the in situ electron microscopy technique. The three stages of film growth, namely, the nucleation, growth of islands followed by liquid-like coalescence have been observed in both the vacuum vapor deposited and ion beam sputtered thin films. The mechanisms of nucleation and growth of silver films formed by ion beam sputtering on the (111) plane of silicon comprise the subject of this paper. A novel mode of epitaxial growth is observed to that seen previously.The experimental arrangement for the present study is the same as previous experiments, and the preparation procedure for obtaining thin silicon substrate is presented in a separate paper.

Extensive Damage

With the advent of the space age and the need to determine the requirements for a space cabin atmosphere, oxygen effects came into increased importance, even though these effects have been the subject of continuous research for many years. In fact, Priestly initiated oxygen research when in 1775 he published his results of isolating oxygen and described the effects of breathing it on himself and two mice, the only creatures to have had the “privilege” of breathing this “pure air”.Early studies had demonstrated the central nervous system effects at pressures above one atmosphere. Light microscopy revealed extensive damage to the lungs at one atmosphere. These changes which included perivascular and peribronchial edema, focal hemorrhage, rupture of the alveolar septa, and widespread edema, resulted in death of the animal in less than one week. The severity of the symptoms differed between species and was age dependent, with young animals being more resistant.
