This study confirmed the prevalence of the intestinal fluke Haplorchis taichui (Trematoda: Heterophyidae) among people and fish in Luang Prabang Province, Lao PDR. Fecal specimens were collected from 559 riparian people (229 males and 330 females), residing in 4 Districts (Luang Prabang, Xieng Ngeun, Pak Ou, and Nam Bak) and were examined by the Kato-Katz fecal smear technique. The overall helminth egg positive rate was 64.9%. The positive rate for small trematode eggs (STE), which may include H. taichui and other heterophyids, Opisthorchis viverrini, and lecithodendriids, was 15.2%. For recovery of adult helminths, 10 STE-positive people were treated with 40mg/kg praziquantel and 15mg/kg pyrantel pamoate, and then purged. Mixed infections with 3 Haplorchis species (H. taichui, H. pumilio, and H. yokogawai), a species of cestode (Taenia saginata), and several species of nematodes including Enterobius vermicularis and hookworms were found. The worm load for trematodes was exclusively high for H. taichui with an average of 7691 specimens per infected person, followed by H. yokogawai (8.3 specimens) and H. pumilio (4.1 specimens). Out of 207 freshwater fish (17 species) purchased in a market in Luang Prabang District, 138 (67%) harboured H. taichui metacercariae (metacercarial burden per fish; 520). Lower prevalence of fish and lower metacercarial density were observed for H. yokogawai (52% and 50 per fish, respectively) and H. pumilio (18% and 3 per fish, respectively). STE found in the surveyed population of Luang Prabang Province were verified to be those of intestinal fukes, particularly H. taichui.

In the last ten years there has been a dramatic change in the electrical industry regarding its technology and capability. VLSI circuits technologies have brought about the develoment of computers, digital communications, digital control systems, and others. The microprocessor now is appearing in the simplest appliances as well as in complex systems, permeating all of engineering. This paper is presented as a proposal for a more improved education courses for technical high school students preparing to enter this dynamic electronic industry. The current curricula, and their syllabuses, of the electronic deparments of typical technical high schools were analyzed, and their teachers and instructors, as well as technicians in electronic companies, were consulted about the education courses. The results of this study are follow: 1. The fields of digital circuits and systems using IC and LSI should be emphasized in the current curricula and the subject of microprocessor applications should be added. 2. The current ratio of the theoretical; subject hours vs laboratory /shop practice hours should be rearranged at about same ratio through effective laboratory systems. 3. A retraining course for experimental instructors and supervisors should be provided, similar to that provided for teachers. 4. Technical high school education should avoid the erroneous philosophy of training the student only sufficiently to pass the qualification examination.

Many alloplastic materials have been used as the bony substitute in large bony defects caused by fracture, periodontitis, & cyst, etc. Nowadays Hydroxyapatite(HAP) is the most usable material as the bony substitute. The reasonable properties of HAP are nontoxic, biocompatible to host tissues & have osteoconductivity. Other bioceramic materials are recommended as the bony substitute with high success rate. We have studied the clinical use of HAP as the bony substitute in the defected area caused by cyst. The reasonalbe & successful results are obtained. The results were as followed. 1. Better prognosis was obtained in the case of HAP & bone mixed graft than HAP graft only. And the best prognosis was obtained in the case of iliac bone graft. 2. Better prognosis was obtained in Mx. than in Mn. 3. It seems that the soft tissue ingrowth into the HAP granule play an importnat role in the success of the HAP graft. 4. Though the flap covering the HAP granules was perforated, the relative good prognosis was obtained by re - suturing the perforeated site.

Odontogenic cyst has been reviewed with a report on the 193 cases clinico-statistically. We found that cysts occur frequently at third decade male as 29% and second decade female as 30%. Maxilla is prevalent site as 74.6% than mandible. Uper incisiors and lower third molars are the most prebalant teeth. Swelling is the most frequent chief complaint. After enucleating, we grafted to the cystic cavities in 10 cases.

Enhanced electrical stability of nitrate ligand-based hexaaqua complexes solution-processed ultrathin a-IGZO transistors

Choi, C,Baek, Y,Lee, B M,Kim, K H,Rim, Y S IOP 2017 Journal of Physics. D, Applied Physics Vol.50 No.48

<P>We report solution-processed, amorphous indium–gallium–zinc-oxide-based (a-IGZO-based) thin-film transistors (TFTs). Our proposed solution-processed a-IGZO films, using a simple spin-coating method, were formed through nitrate ligand-based metal complexes, and they were annealed at low temperature (250 °C) to achieve high-quality oxide films and devices. We investigated solution-processed a-IGZO TFTs with various thicknesses, ranging from 4 to 16 nm. The 4 nm-thick TFT films had smooth morphology and high-density, and they exhibited excellent performance, i.e. a high saturation mobility of 7.73  ±  0.44 cm<SUP>2</SUP> V<SUP>−1</SUP> s<SUP>−1</SUP>, a sub-threshold swing of 0.27 V dec<SUP>−1</SUP>, an on/off ratio of ~10<SUP>8</SUP>, and a low threshold voltage of 3.10  ±  0.30 V. However, the performance of the TFTs degraded as the film thickness was increased. We further performed positive and negative bias stress tests to examine their electrical stability, and it was noted that the operating behavior of the devices was highly stable. Despite a small number of free charges, the high performance of the ultrathin a-IGZO TFTs was attributed to the small effect of the thickness of the channel, low bulk resistance, the quality of the a-IGZO/SiO<SUB>2</SUB> interface, and high film density.</P>
