Effective Integration of Technology in a High School Beginning Japanese Class

Technological advancement is rapidly changing our daily lives. Many teachers seek ways to implement technology to improve students’ learning experiences. How do we determine what types of technological tools to use to maximize learning? This research investigated the effectiveness of the integration of the Substitution Augmentation Substitution and Redefinition (SAMR) model and other web applications in learning Japanese at the high school level. Fifty-one students in first-year Japanese language classes participated in a technology-integrated lesson. Technology-enhanced activities were selected with the SAMR model and were developed for students to learn and demonstrate Japanese language skills and cultural knowledge in a learning sequence based on second language theories. A pre-survey, formative assessments, summative assessments, homework logs, a post survey, and a teacher journal were analyzed to determine the effectiveness of such integration and its influences on learners’ language performance and motivation. Results indicated that students’ language performance increased in both interpretive and presentational modes of communication, however, there was no significant improvement in the interpersonal mode of communication. In addition, students also developed learning strategies with technology as they shared them with their peers

Pandangan Ushul Fikih Al-Qurthubi dalam Penafsiran Ayat-Ayat Jual Beli

Ushul fikih digunakan oleh mufasir sebagai pendekatan dalam menafsirkan ayat-ayat hukum dalam Al-Qur’ān. Salah satu kitab tafsir yang menarik untuk dibahas dari sisi ushul fikihnya adalah Al-Jāmi’ li Ahkām al-Qurān karya Imam al-Qurthubi (w. 671 H). Tafsir milik al-Qurthubi merupakan tafsir bercorak fikih yang tidak mengedepankan fanatisme mazhab meskipun al-Qurthubi bermazhab Maliki, beliau lebih memihak kepada pendapat yang lebih bijak. Tulisan ini merupakan penelitian pustaka yang menggunakan metode deskriptif-analitis dengan data berupa penafsiran al-Qurthubi tentang 4 ayat Al-Qur’ān yang membahas hukum jual beli. Penelitian ini bertujuan untuk mengetahui pandangan al-Qurthubi sebagai mufasir sekaligus fakih tentang penerapan kaidah ushul fikih, metode istinbat dan pendekatan tafsir yang digunakan dalam menafsirkan ayat-ayat jual beli, serta untuk melihat pandangan ushul fikih al-Qurthubi yang sejalan dengan prinsip ekonomi Islam. Melalui penelitian ini ditemukan bahwa ushul fikih melekat pada tafsir al-Qurthubi. Beliau selalu menerapkan kaidah-kaidah yang beragam dalam menggali hukum pada ayat jual beli. Pandangan beliau dalam ushul fikih dan hukum fikih terlebih dahulu dibandingkan dengan pendapat ulama lain sebelum ditegaskan mana yang menurut beliau lebih sahih

Analysis of a change in bacterial community in different environments with addition of chitin or chitosan

The temporal changes of a bacterial community in soil with chitin or chitosan added were analyzed by PCR-denaturing gradient gel electrophoresis (DGGE) targeting the 16S rRNA gene using total DNAs prepared from the community. Band patterns of PCR-DGGE confirmed that 31 species become predominant after the addition of chitin or chitosan. The determination of the nucleotide sequences of the bands of the 31 species indicated that 20 species belonged to the division Proteobacteria, and that the genus Celivibrio was apparently predominant among them (7/20). The 16S rRNA sequences of the 16 deduced species (16/31) showed less than 98% similarities to those of previously identified bacteria, indicating that the species were derived from unidentified bacteria. The total community DNAs extracted from bacterial cells adsorbed on the surface of flakes of chitin and chitosan placed in a river, a moat, or soil were subjected to PCR-DGGE to examine the extent of diversity of chitinolytic bacteria among different environments. The predominant species significantly differed between the chitin and chitosan placed in the river and moat, but not so much between those placed in the soil. The large difference between the diversities of the three bacterial communities indicated that a wide variety of bacteria including unidentified ones are involved in the degradation of chitin and chitosan in the above-mentioned natural environments.

Magnetic resonance (MR) imaging assessment for glossopharyngeal neuralgia : value of three-dimensional T2-reversed MR imaging (3D-T2R) in conjunction with other modes of 3D MR imaging

Background: To retrospectively examine the usefulness of gray-scale reversal imaging of T2-weighted images (3D-T2R) in conjunction with other modes of 3D MRI for preoperative assessments in patients with glossopharyngeal neuralgia (GPN) due to neurovascular compression. Material/Methods: Imaging findings on 3D-T2R, constructive interference in steady state (CISS), and MRA were analyzed with reference to operative charts in 10 patients with GPN. Results: Offending vessels were associated with the posterior inferior cerebellar artery (PICA) in 9 of 10 patients (90%). Eight of the 10 patients (80%) had offending vessels located at the supraolivary fossette. Of those eight patients, six (75%) had a shift of the ipsilateral vertebral artery to the affected side. Five (42%) and seven (48%) contact points were associated with the root entry/exit zone and the peripheral nerve system segment, respectively. In six of nine contact points (67%), 3D-T2R demonstrated the pathomorphological features at the contact points better than CISS. Conclusions: The offending vessels were mostly associated with posterior inferior cerebellar arteries, were frequently located at the supraolivary fossette, and had attachments at the root entry/exit zone and at the peripheral segment of the glossopharyngeal nerve, which was well demonstrated on 3D-T2R

Medical Tourism-Issues in Nigeria

This study was carried out with the aim of evaluating the effects medical tourism has on Nigeria. This was done focusing on the trends on three major concerns which are: the effect of medical tourism on the health status of Nigerians, the effect of medical tourism on Nigeria’s economy and lastly, why medical tourism by Nigerians despite the development in our medical sector. Data for this study were collected majorly from secondary sources and the Desk review method of data analysis was used. This primarily entails the examination and evaluation of several studies using the Scoping review research design of collecting and collating important information for the research. This allowed for expansion of knowledge on other key areas that were not related to the scope of study, such as social health development and several others. Findings revealed that indeed, medical tourism by Nigerians has had some effects on several sectors of the country, one of which is a reduction in the revenue for sustaining the source country’s (Nigeria) local health sector and as a result, leads to poor performance on the medical officers, as they are short of logistics and facilities and in turn leads to lack of trust in medical practitioners and also high mortality rate. If the millions of Naira spent by some Nigerian government officials and the Nigerian elites on medical tourism abroad, are put into effective infrastructural development and are made to receive medical treatments here in Nigeria, they would indeed be doing the economy and the general image of the nation’s health status /sector a lot of good. Keywords: Medical tourism, health, scoping review research design DOI: 10.7176/DCS/10-8-05 Publication date:August 31st 2020

New bobtail squid (Sepiolidae: Sepiolinae) from the Ryukyu islands revealed by molecular and morphological analysis

Bobtail squid are emerging models for host-microbe interactions, behavior, and development, yet their species diversity and distribution remain poorly characterized. Here, we combine mitochondrial and transcriptome sequences with morphological analysis to describe three species of bobtail squid (Sepiolidae: Sepiolinae) from the Ryukyu archipelago, and compare them with related taxa. One Ryukyuan type was previously unknown, and is described here as Euprymna brenneri sp. nov. Another Ryukyuan type is morphologically indistinguishable from Sepiola parva Sasaki, 1913. Molecular analyses, however, place this taxon within the genus Euprymna Steenstrup, 1887, and additional morphological investigation led to formal rediagnosis of Euprymna and reassignment of this species as Euprymna parva comb. nov. While no adults from the third Ryukyuan type were found, sequences from hatchlings suggest a close relationship with E. pardalota Reid, 2011, known from Australia and East Timor. The broadly sampled transcriptomes reported here provide a foundation for future phylogenetic and comparative studies

Diversification of mandarin citrus by hybrid speciation and apomixis

The origin and dispersal of cultivated and wild mandarin and related citrus are poorly understood. Here, comparative genome analysis of 69 new east Asian genomes and other mainland Asian citrus reveals a previously unrecognized wild sexual species native to the Ryukyu Islands: C. ryukyuensis sp. nov. The taxonomic complexity of east Asian mandarins then collapses to a satisfying simplicity, accounting for tachibana, shiikuwasha, and other traditional Ryukyuan mandarin types as homoploid hybrid species formed by combining C. ryukyuensis with various mainland mandarins. These hybrid species reproduce clonally by apomictic seed, a trait shared with oranges, grapefruits, lemons and many cultivated mandarins. We trace the origin of apomixis alleles in citrus to mangshanyeju wild mandarins, which played a central role in citrus domestication via adaptive wild introgression. Our results provide a coherent biogeographic framework for understanding the diversity and domestication of mandarin-type citrus through speciation, admixture, and rapid diffusion of apomictic reproduction
