Published: September 2016

ObjectivesThis study aimed to develop the Career Anchors Scale among Occupational Health Nurses (CASOHN) and evaluate its reliability and validity.MethodsScale items were developed through a qualitative inductive analysis of interview data, and items were revised following an examination of content validity by experts and occupational health nurses (OHNs), resulting in a provisional scale of 41 items. A total of 745 OHNs (response rate 45.2%) affiliated with the Japan Society for Occupational Health participated in the self‐administered questionnaire survey.ResultsTwo items were deleted based on item‐total correlations. Factor analysis was then conducted on the remaining 39 items to examine construct validity. An exploratory factor analysis with a main factor method and promax rotation resulted in the extraction of six factors. The variance contribution ratios of the six factors were 37.45, 7.01, 5.86, 4.95, 4.16, and 3.19%. The cumulative contribution ratio was 62.62%. The factors were named as follows: Demonstrating expertise and considering position in work (Factor 1); Management skills for effective work (Factor 2); Supporting health improvement in groups and organizations (Factor 3); Providing employee‐focused support (Factor 4); Collaborating with occupational health team members and personnel (Factor 5); and Compatibility of work and private life (Factor 6). The confidence coefficient determined by the split‐half method was 0.85. Cronbach's alpha coefficient for the overall scale was 0.95, whereas those of the six subscales were 0.88, 0.90, 0.91, 0.80, 0.85, and 0.79, respectively.ConclusionsCASOHN was found to be valid and reliable for measuring career anchors among OHNs in Japan.

Published: September 2016

ObjectivesThis study investigated the actual situation of noise and low‐frequency sounds in firework events and their impact on pyrotechnicians.MethodsData on firework noise and low‐frequency sounds were obtained at a point located approximately 100 m away from the launch site of a firework display held in “A” City in 2013. We obtained the data by continuously measuring and analyzing the equivalent continuous sound level (Leq) and the one‐third octave band of the noise and low‐frequency sounds emanating from the major firework detonations, and predicted sound levels at the original launch site.ResultsSound levels of 100‐115 dB and low‐frequency sounds of 100‐125 dB were observed at night. The maximum and mean Leq values were 97 and 95 dB, respectively. The launching noise level predicted from the sounds (85 dB) at the noise measurement point was 133 dB. Occupational exposure to noise for pyrotechnicians at the remote operation point (located 20‐30 m away from the launch site) was estimated to be below 100 dB.ConclusionsPyrotechnicians are exposed to very loud noise (>100 dB) at the launch point. We believe that it is necessary to implement measures such as fixing earplugs or earmuffs, posting a warning at the workplace, and executing a remote launching operation to prevent hearing loss caused by occupational exposure of pyrotechnicians to noise. It is predicted that both sound levels and low‐frequency sounds would be reduced by approximately 35 dB at the remote operation site.

Published: September 2016

Acinetobacter baumannii is a ubiquitous pathogen that has emerged as a major cause of healthcare-associated infections at Ladoke Akintola University Teaching Hospital. Isolates were assayed according to standard protocol. The isolates were subjected to molecular techniques to detect blaOXA, blaTEM, blaCTX-M, and blaSHV genes in strains of the A. baumannii isolates.
The prevalence of A. baumannii was 8.5% and was most prevalent among patients in the age group 51–60 (36%); the male patients (63.6%) were more infected than their female counterparts. Patients (72.7%) in the intensive care unit (ICU) were most infected with this organism. The isolates showed 100% resistance to both amikacin and ciprofloxacin and 90.9% to both ceftriaxone and ceftazidime, while resistance to the other antibiotics used in this study were: piperacillin (81.8%), imipenem (72.7%), gentamycin (72.2%), and meropenem (63.6%). None of the isolates was, however, resistant to colistin. PCR results showed that blaOXA, blaTEM, and blaCTX-M genes were positive in some isolates, while blaSHV was not detected in any of the isolates.
This study has revealed that the strains of A. baumannii isolated are multiple drug resistant. Regular monitoring, judicious prescription, and early detection of resistance to these antibiotics are, therefore, necessary to check further dissemination of the organism.

Published: September 2016

Infection of Megalocytivirus cause serious mass mortality in marine fish in South East Asian countries. The aim of this study was to produce recombinant of GSDIV capsid protein and its protection to humpback grouper Cromileptes altivelis against grouper sleepy disease iridovirus (GSDIV). A major capsid protein (MCP) was selected for use as a crude subunit vaccines. This gene target (MCP) was inserted to the protein expression system vector of pET SUMO and cloned in cells bacteria Escherichia coli strain BL-21. The MCP was succeded to be induced using 1 mM of IPTG. Results of protein analysis using MALDI TOF-TOF indicated that the MCP has measurement of 49.566 kDa with PI index of 6.00, and contained 453 amino acids. BLAST homology analysis exhibited that the amino acid sequence of the MCP showed high similarity with MCP of Red Sea Bream Iridovirus (RSIV). E. coli expressing MCP protein was inactivated using 0.03% formalin overnight and washed using PBS. The inactivated E. coli as a crude subunit vaccine was then injected intramuscularly to humpback grouper juveniles. Subsequently, the juveniles were challenged tested with GSDIV. The juveniles vaccinated with the MCP recombinant bacteria showed significantly higher survival rates than control those vaccinated with PBS. Thus, the MCP fusion protein is considered as a potential vaccine against GSDIV infections in grouper.

Published: September 2016

<p>Ikan Malalugis adalah ikan pelagis kecil yang merupakan hasil tangkapan utama nelayan di perairan Laut Sulawesi. Pada tahun 2012 dilaporkan bahwa perikanan pelagis kecil menjadi salah satu hasil perikanan yang penting, dan hasil tangkapan yang dominan dari perikanan pelagis kecil tersebut adalah ikan malalugis biru (Decapterus macarellus). Jenis ikan malalugis memiliki sifat bermigrasi dan membentuk gerombolan kecil yang mana sangat dipengaruhi oleh kondisi lingkungannya. Tipe arus pasut di Teluk Manado (Laut Sulawesi) merupakan arus pasut bolak balik (reversing current). Banyaknya arus yang begitu aktif merupakan salah satu faktor yang mendukung habitat ikan malalugis. Diduga kekhasan sifat distribusi arus di daerah laut Sulawesi ini yang membuat kelimpahan ikan malalugis relatif tinggi di perairan Sulawesi Utara dibandingkan dengan daerah perairan lainnya di Indonesia. Kelimpahan ikan malalugis yang tinggi mendorong ikan ini menjadi komoditas penting dalam sektor perikanan di Laut Sulawesi. Meski demikian pada tahun 2012 dilaporkan bahwa tingkat produksi ikan malalugis mengalami penurunan. Hal ini diduga karena terlalu tingginya tingkat eksploitasi atau diakibatkan oleh adanya perubahan dalam kondisi ekosistem ikan tersebut di Laut Sulawesi. Oleh karena itu studi ini dilakukan untuk mengkaji tingkat daya dukung lingkungan terhadap keberlangsungan sumberdaya perikanan malalugis di wilayah perairan Laut Sulawesi.</p><p><br /><em>Malalugis fish is a small pelagic fish that constitute the main catch of fishermen in the waters of North Celebes Sea. In 2012 it was reported that small pelagic fishery became one of the important fishery products and it was dominated by the species of Malalugis (Decapterus macarellus). This species has a typical behavior which was highly mobility and forming fish schooling and strongly influenced by environmental conditions. The type of tidal current in North Sulawesi coast is reversing current. This kind of current could make a very active current in the water which is suitable for the habitat of Malalugis. This distinctiveness of current was considered as a trigger for relatively high abundance of Malalugis in this area compared to its </em><em>abundance in other water body of Indonesian territory. In 2012, total catch of this species has been reported to be decreased; thismay caused by either high level of exploitation nor changing on its habitat or even both. This study was conducted to investigate the capability of ecosystem and habitat of Malalugis to support its sustainability.</em></p>

<em>Essa revisão de literatura objetiva identificar os efeitos da aplicação de cinza de biomassa vegetal sobre atributos do solo e sobre o crescimento e produção de espécies vegetais. A cinza de biomassa tem sido gerada por diversas atividades industriais e agroindustriais, sendo produzidas grandes quantidades de resíduo. A utilização agrícola desse material é uma alternativa ecologicamente correta e economicamente viável. A composição das cinzas é variável, sendo assim as modificações causadas no solo e resposta das culturas também variável. As principais alterações químicas resultantes da aplicação de cinza de biomassa, são elevação no pH e nos teores de Ca, Mg, K e P, além da redução dos teores de Al<sup>3+</sup>. A elevação do pH causado pela cinza estimula a atividade biológica favorecendo a decomposição de matéria orgânica e a atividade de algumas enzimas. A cinza pode elevar a retenção de água. A aplicação de cinza de biomassa tem elevado a altura das plantas, o seu diâmetro, número de folhas, massa seca da parte aérea e raízes, bem como o teor foliar de clorofila e nutrientes em diversas espécies, tanto olerícolas, como anuais e perenes, a exemplo da alface, azevém, aveia, milho, sorgo, algodão, girassol, mamona, café, bananeira, campins, pinus e eucalipto.</em>

Published: September 2016

<p>A inovação e a sustentabilidade caracterizam os principais critérios a serem considerados na gestão dos Resíduos de Equipamentos Eletroeletrônicos (REEE). O descarte inadequado dos REEE tem fomentado discussões no âmbito político e técnico por duas razões principais: o impacto negativo da contaminação ambiental por metais e o consumo energético ao longo de sua vida útil, que demandam uma busca pelo desenvolvimento de soluções otimizadas e de baixo custo. A Política Nacional de Resíduos Sólidos – Lei 12.305 –, em agosto de 2010, estabelece uma responsabilidade compartilhada pelo ciclo de vida dos produtos, abrangendo desde os fabricantes, consumidores e responsáveis pelos serviços públicos de limpeza urbana e manejo de resíduos sólidos. Entre esses resíduos, os plásticos de comodittes têm despertado grande interesse da população, sendo o polietileno de alta densidade (PEAD) um dos materiais que se encontra em maior proporção volumétrica nos resíduos sólidos urbanos. Foram preparados compósitos poliméricos à base de PEAD reciclado e virgem,<br />reforçados com resíduo de toner e negro de fumo. Os materiais foram caracterizados através do DRX, TGA e DSC. Observou-se que os reforços poderão conferir diferentes características – tais como a possível elevação<br />da estabilidade térmica com o negro de fumo –, enquanto o toner não afeta significativamente as propriedades do PEAD.</p>

Learning analytics has been as used a tool to improve the learning process mainly at the micro-level (courses and activities). However, another of the key promises of Learning Analytics research is to create tools that could help educational institutions at the meso- and macro-level to gain a better insight of the inner workings of their programs, in order to tune or correct them. This work presents a set of simple techniques that applied to readily available historical academic data could provide such insights. The techniques described are real course difficulty estimation, course impact on the overall academic performance of students, curriculum coherence, dropout paths and load/performance graph. The usefulness of these techniques is validated through their application to real academic data from a Computer Science program. The results of the analysis are used to obtain recommendations for curriculum re-design.

Published: September 2016

Case:
Giant cell tumor (GCT) of bone was first described almost 200 years ago, but the optimal treatment continues to evolve. We present a patient with a pelvic GCT who was treated with embolization, 20 months of denosumab therapy, and resection. Histologically, the tumor consisted of degenerated GCT, bone, and fibrous tissue. After 7 months, the patient was found to have osteosarcoma at the site of the initial lesion as well as pulmonary metastases.

Conclusion:
The apparent malignant transformation of a GCT of bone treated initially with denosumab indicates that close follow-up is warranted.

Published: September 2016

Case:
We present a rare case of an intramedullary osteolipoma without any extramedullary connections or coexisting spinal dysraphism. A 48-year-old woman presented with back pain and pain around the lateral aspect of the left thigh. Magnetic resonance imaging (MRI) revealed a heterogeneous hyperintense and hypointense region on T1 and T2-weighted imaging. A cavernous hemangioma was suspected, and the patient was admitted for surgical resection. The histological diagnosis was an intramedullary osteolipoma.

Conclusion:
MRI with fat suppression and computed tomography are recommended for the diagnosis of an intramedullary osteolipoma, but a definitive diagnosis requires histological examination.
