No full textUbiquitous healthcare: Technology and service
No full textUbiquitous healthcare is introduced in terms of technology and service, considering the current technology as well as the future technology and services. In the first section, we introduce the key techniques of ubiquitous healthcare for next-generation medical treatment services. In the second section, we introduce the wireless sensor network (WSN) and ANTS (an Evolvable Network of Tiny Sensors). In the last section, we discuss real-time health-monitoring network for the disabled and elderly people using an inexpensive and effective Web server and health-monitoring sensors in a wrist phone. © Springer-Verlag Berlin/Heidelberg 2006

Mesopleuron, mesoscutum, scutellum, metanotum and propodeal lateral face with dense medium-sized punctures regularly set. Propodeal impression almost an isosceles triangle in shape, and ca. 2.0 × as long as broad. Propodeal dorsum weakly reticulate. Metasoma. Lateral parts of terga II–III, lateral parts and dorsum of terga IV–V, apical parts of sterna II–V and lateral parts of sternum VI with long sparse brownish bristles. Terga I–V and sterna II–III with small punctures moderately (separating one another by puncture diameter or a little more) and regularly set; sterna IV–V with small to medium-sized punctures moderately and irregularly set; sternum VI with both sparse medium-sized and large punctures irregularly set. Pygidial plate almost an equilateral triangle in shape with apical margin shortly truncate (Fig. 3 C). Coloration. Ground color black, following parts brown to reddish brown: basal half of mandible, palpi, tegula, apical half or slightly less of all femur, all tibiae, all trochanters and spurs and spines of all legs. Male. As in female, but different in following details. Body smaller, 12.3–14.3 mm long. MID ca. 2.9 × as long as LID (Fig. 2 J). Bristles on pygidial plate pale golden. Genitalia. As in Fig. 4 H (dorsal view) and Fig. 4 I (lateral view): gonocoxite broad and tapering, without distinct tubercle in its proximal part; middle constriction of aedeagus inconspicuous. Type-specimens.

Etymology. Specific name is given in memory of the late Dr. C.W. Kim who was a founder entomologist of Hymenoptera taxonomy in Korea. GYUSAN is his added name. Distribution. South Korea. Remarks. This new species superficially resembles Tachytes modestus in setal condition and coloration (Fig. 1 D and E). However, in addition to several distinctive characteristics given in the key, male genital structure is critically different: in the new species, the distal triangular part of the aedeagus is longer in dorsal view, and the gonocoxite is broad and evenly tapering, without proximal tubercle; the corresponding part of the aedeagus is shorter and the gonocoxite is narrower and rod-shaped, with a triangular proximal tubercle in T. modestus. Setal condition of the propodeal dorsum is unique in the new species. The median longitudinal part of the propodeal dorsum is covered with dense appressed setae in the new species (Fig. 3 B), whereas the narrow median longitudinal linear area (i.e., shallow longitudinal furrow) is almost bare in the other Korean species (Fig. 3 E). This new species was very often observed on flowers of Zanthoxylum schinifolium S. et Z. (Rutaceae) during late June to early September.Published as part of Back, Yeong-Bin & Kim, Jeong-Kyu, 2014, Review of the genus Tachytes Panzer (Hymenoptera: Crabronidae: Crabroninae) of South Korea, with description of one new species, pp. 301-310 in Zootaxa 3795 (3) on pages 304-307, DOI: 10.11646/zootaxa.3795.3.5, http://zenodo.org/record/23030
A novel bioreactor for the biodegradation of inhibitory aromatic solvents: Experimental results and mathematical analysis
No full textA novel bioreactor for the biodegradation of toxic aromatic solvents, such as benzene, toluene, and xylenes in liquid effluent stream, was developed. Silicon tubing was immersed in the completely mixed and aerated bioreactor, and liquid toluene as a model solvent was circulated within the tubing. Toluene diffused out of the tube wall and was transferred at high rate into the culture broth, where biodegradation occurred. The effect of operating parameters on the toluene transfer rate was investigated. During continuous operation, the biodegradation rate was considerably higher than those obtained using conventional methods. A mathematical model was established for continuous biodegradation, and simulation results coincided with the experimental results. The performance and operational criteria of the bioreactor were analyzed on the basis of both the experimental and simulation results
