Authors: Wilson Jerry
Published: February 2020

Implementasi Digital Tourism/E-Tourism sangat berpotensi dalam meningkatkan Tingkat Hunian Homestay di Kabupaten Humbahas khususnya Kecamatan Bakti Raja. Hal ini disebabkan oleh semakin pesatnya pertumbuhan digital information. Semua tempat dan informasi dapat dijangkau dengan menggunakan fasilitas Digital Information. Hal ini berlaku disemua sisi ilmu pengetahuan umat manusia pada Jaman sekarang ini.Dengan menggunakan Digital Information, ilmu pengetahuan berkembang, perekonomian berkembang dan informasi suatu objek dan lokasi juga semakin berkembang. Dengan demikian hal ini berpengaruh dengan perkembangan kegiatan ekonomi pariwisata secara umum. Melalui digital information, banyak tempat dan lokasi wisata akan dipertontonkan kepada dunia sehingga mengundang banyak perhatian. Disamping itu banyak atraksi, hal hal menarik dan kegiatan yang menarik sehingga orang dapat tertarik berkunjung kesana. Maka sarana akomodasi untuk tinggal sementara waktu selama disana akan dibutuhkan. Hal ini adalah merupakan peluang besar bagi masyarakat setempat untuk dapat memamfaatkan situasi tersebut. Maka peluang membuka usaha homestay sangat berpotensi meningkatkan perekonomian masyarakat di lokasi objek wisata tersebut. Tentu nya homestay tersebut dapat diketahui oleh wisatawan keberadaan nya apabila ada promosi atau pemberitahuan melalui media massa seperti Koran, Majalah, Brosur dan lebih terjangkau seperti Layanan Internet atau sering kita sebut Digital Information. Bidang promosi Digital Information ini lebih spesifik kita sebut Digital Tourism atau E-tourism karena secara khusus berhubungan dengan informasi tentang Pariwisata serta Objek Wisata.Berkaitan dengan implementasi Digital Tourism untuk meningkatkan kunjungan wisatawan yang akan menggunakan sarana Homestay ini sangat relevan. Oleh karena dilokasi objek wisata tertentu tidak terdapat Hotel untuk sarana akomodasi. Oleh sebab itu sebagai sarana alternative diperlukan sarana homestay yang memadai sebagai tempat beristirahat sementara di objek wisata tersebut. Oleh karena itu dibutuhkan promosi Homestay secara Digital sebagai suatu cara untuk meningkatkan kunjungan wisatawan pada homestay tersebut.

DINAMIKA KEBIJAKAN HUKUM PIDANA DALAM TINDAK PIDANA PEREDARAN NARKOTIKA OLEH ANAK
Authors: Muis Dulfi
Published: February 2020

Pengedaran narkotika oleh anak, akhir-akhir ini mulai marak seiring dengan perkembangan teknologi dan berbagai kemudahan fasilitas umum.Peredaran narkotika oleh anak sebenarnya merupakan suatu perkara yang harus ditangani secara khusus karena mengancam generasi penerus bangsa.Anak yang menjadi pengedar narkotika tidak terlepas dari jaringan narkotika orang dewasa sehingga dapat diposisikan sebagai korban eksploitasi. Namun dalam Undang-Undang Nomor 35 Tahun 2009 tentang Narkotika tidak ada pembedaan secara khusus usia pelaku pengedar narkotika. Hukum pidana dalam hal ini harus diposisikan sebagai sarana untuk merehabilitasi anak, bukan sebagai sarana untuk menghukum anak.Sehingga dalam hal ini sebenarnya sarana pemidanaan tidak tepat untuk diterapkan.Karena anak yang menjadi pengedar narkotika merupakan korban.Oleh karenanya negara melalui pemerintah dan masyarakat mempeunyai kewajiban untuk melindungi anak yang menjadi korban tindak pidana. Kata kunci :kebijakan pemidaan, peredaran narkotika,anak

The findings of this study would provide better insights to the issues of human rights in the labour market among ASEAN countries. It can serve as a resource for researchers, practitioners and policymakers for policymaking in ensuring that disadvantaged workers are not excluded from being able to fully enjoy their right to work as their participation in the labour market could in turn be one of the solutions to reduce high unemployment rate suffered in some ASEAN countries.
Defining the environmental crime – why is the global legal and political action urgently needed
Authors: Bajrektarevic Anis H
Published: February 2020

Preservation and protection of environment appears as one of the largest challenges of our time. It necessitates urgent but also comprehensive, planetary action. One of the key issues is to define a scope of future international instrument as well as its definition. This requires global political action which will then eventually translate into a coordinated legal action and finally articulate itself in viable international treaty. Institutional collaboration among stakeholders and agencies needs to be improved as much as the currently existing approaches need to be harmonized. Only an improved institutional framework between agencies and stakeholders that protects environment could enhance and accelerate cooperation to the levels equal to an environmental and climate change challenge. The very creation of such framework could also contribute to the harmonization of monitoring and reporting systems. It will also lead to more coordinated, more effective and properly financed policy instruments as well as more efficient legal enforcement on supranational, national and sub-national level.
Odour Assessment for a Pig Farm Through Dynamic Olfactometry and Air Dispersion Modelling in Order to Reduce the Odour Pollution Using Biotechnologies
Authors: Vasile Andrei , Gheorghita Tanase , Babeanu Narcisa , Popa Ovidiu
Published: February 2020

Odour represents one the most actual topics in terms of industrial pig farming pollution effects, mainly because of the increasing number of settlements build in traditional farming areas but also because of the overpopulation of pigsties. The odour impact assessment was requested by a big pig farm in order to comply to the request of the Environmental Agency to reduce the odour impact on nearby settlements. Odour assessment was done using dynamic olfactometry, mathematical modelling of dispersion and FIDOL factors. The initial assessment was used to elaborate and apply an odour management plan based on biotechnologies which consisted mainly in biological treatments applied to the floor of the pigsties, the slurry transportation channels and the slurry tanks with specific products designed to reduce the Ammonia level, break down her sulphurous compounds in the slurry and increase the quality of the slurry as fertilizer, with the final target of reducing the odour emissions. Results indicate a considerable decrease of odour concentrations in the closest settlements, around the farm and inside pigsties. Further measures must be taken as the concentrations are still over the limit values from most European countries.

Published: February 2020

The uses of herbicides increased during the last decades. Because acid herbicides can be identified in environmental samples, specific analytical methods are required. In this work a new GC-MS/MS method was developed in order to detect some pyridinecarboxylic acids (clopyralid, triclopyr and fluroxypyr) and a methoxybenzoic acid (dicamba) from environmental water samples. Because these polar analytes involve a derivatization step, a Programmed Temperature Vaporizing injector (PTV) was used to shape the derivatization conditions and to minimize the working time. This process is called in port derivatization (IPD), a relative new technique which encourages greener practices in analytical laboratory. MtBSTFA was chosen to be the most suitable silylation agent due to generation of specific derivatized analyte structures, which can be further fragmented in the EI ionization source to produce specific ions for the targeted analytes, easily detectable with high sensitivity.Few studies analyzed the derivatization of above-mentioned herbicides with MtBSTFA, while no other paper work was identified in studying the in port derivatization of these compounds. The results revealed that the developed method is sensitive and robust to obtain quantitation limits below 10 ng/L.

Published: February 2020

A preliminary stage in developing numerical simulations of a biological process for wastewater treatment consists in evaluating the kinetic parameters of the studied process. The study shows results obtained by experimental and numerical evaluation of mixed microalgae-bacteria granules kinetical parameters. The results showed that operational parameters modulated the main kinetic parameters of biological processes involved in removal of organic load and nutrients from wastewater such as biomass production coefficient, endogenous decomposition rate, specific peak rate of growth, semisaturation constant, specific rate of nitrification and the specific denitrification speed. These key parameters were determined over time to evaluate the performance of microbial populations in microalgae-bacteria granules in different operational conditions. Tests have been carried out for various wastewater compositions to determine the versatility and adaptability of the technology.

Published: February 2020

The present works deals with waste heat recovery from internal combustion engines using Rankine cycle systems where working fluid are organic liquids (ORC). The first part of the paper presents the ORC technology as one of the most suitable procedure for waste heat recovery from exhaust gas of internal combustion engine (ICE). The particular engine considered in the present work is a turbocharged compression ignition engine mounted on an experimental setup. The working fluids for ORC system are: isobutene, propane, RE245fa2, RE245cb2, R245fa, R236fa, R365mfc, R1233zd(E), R1234yf and R1234ze(Z). Experimental data derived from the experimental setup has been used for 40%, 55% and 70% engine load. This papers focusses on superheating increment, on thermal efficiency and on net power output, obtained with each working fluids in Rankine cycle. Results point out the superheating increment that gives the highest thermal efficiency for each working fluid. The highest thermal efficiency is achieved in case of using R1233zd(E) as working fluid. In case of using R1233zd(E) as working fluid at 40 % load of the engine, the output power of the Rankine cycle is 3.6 kW representing 6.2 %, from the rated power at this load; at 55% load it is 5.7 kW representing 6.7 % the rated power and at 70% it is 6.7 kW representing 6.5 % from the rated power. Future perspectives are given.

Published: February 2020

Given the need for the development of interdisciplinary studies and research, including in the Engineering field and in the Building sector, this paper suggests a multidisciplinary approach to the maintenance of lithic surfaces, by analyzing some high-performance building materials and products, such as hydrophobization coating films. As it has been determined and acknowledged by the scientific community worldwide, the main aggression factor affecting the geomaterials used in the construction of heritage assets is represented by water and/or excessive humidity, especially in the case of the use of porous limestone, such as those available in the Repedea - Iasi area (Romania). Therefore, in order to ensure better maintenance of a lithic calcareous material of this type, it is necessary to use a hydrophobic preventive treatment. The findings of the research conducted and described in this paper represent one of the first steps on the path to standardization regarding the confirmation of the efficiency of the hydrophobization products, which have been increasingly present on the Romanian specialized market lately. Thus, this paper is addressed to all the specialists interested in maintaining the lithic surfaces exposed to various environmental factors, as it is useful for both historical and civil constructions.

The objective of this paper is to evaluate the rate of detection of chromosomal abnormalities through the non-invasive prenatal test (NIPT) and its contribution to reducing the number of invasive tests. We conducted a prospective study on a batch of 3,000 single-pregnancy pregnancies highlighted in the first trimester. The patients were divided into two study groups, the first group, which we will call the TPNI (Non-Invasive Prenatal Test) group. First trimester screening was performed by non-invasive prenatal test at 10 weeks, and ultrasound between 11-13 +/- 6 days according to the criteria of the Fetal Medicine Foundation (FMF. London, UK). The sensitivity, specificity and accuracy of the two screening methods are almost similar, using NITP screening we obtain a rate of approximately 20% lower false-positive results, and we also perform a smaller number of invasive tests.

Published: February 2020

CAD/CAM procedures are increasingly used to the manufacturing of 3D-designed PMMA interim dental crowns. The aim of this in vitro study was to compare the internal fit of interim PMMA crowns fabricated by subtractive versus additive CAD/CAM procedures. Starting from a Co-Cr CAD/CAM master abutment model, 20 standardized dental models of dental stone were done by double impression technique. Subsequently two groups of interim PMMA interim crowns, each of them having 10 specimens, were CAM obtained either by milling or 3D printing, using Exocad software package, milling machine Rolland DWX-50, and the 3D printer MoonRay S 100 respectively. An electronic digital caliper Powerfix Profi+ was used for measurements of the chrome cobalt abutment and crowns inner diameter in 4 directions (mesial-distal gingival, buccal-lingual gingival, mesial-distal occlusal, and buccal-lingual occlusal). The null hypothesis that the internal dimensional accuracy of interim PMMA crowns fabricated by DLP additive method would not be different compared to those obtained by milling procedure was rejected since the printed PMMA interim crowns were more accurate. This study concluded that the milled PMMA interim crowns show larger internal dimensional variations than the 3D printed ones. However, the fit variation among interim crowns fabricated by both procedures was statistically non significant, so that both CAM technologies may be equally used in manufacturing process.

Authors: Ingley K. M. , Cohen-Gogo S. , Gupta A. A.
Published: February 2020

Soft-tissue sarcoma (STS) is rare and represents approximately 7% of cancers in children and in adolescents less than 20 years of age. Rhabdomyosarcoma (RMS) is most prevalent in children less than 10 years of age and peaks again during adolescence (16–19 years of age). Multi-agent chemotherapy constitutes the mainstay of treatment for RMS. In other non-rhabdomyosarcoma soft-tissue tumours, such as synovial sarcoma, evidence for routine use of chemo-therapy is less robust, and alternative treatment options, including targeted agents and immunotherapy, are being explored. In this review, we focus on chemotherapy for pediatric-type RMS and discuss the advances and challenges in systemic treatment for select non-rhabdomyosarcoma soft-tissue tumours in children and adolescents. We  support an increasingly cooperative approach for treating pediatric and adult STS.

Examining the Effects of Types of Pretask Planning on Oral Performances
Authors: Ogawa Chie
Published: February 2020

In this study, I explored the effects of pretask planning on the oral performance in monologue tasks of Japanese university students. The participants in this study were 29 first-year Japanese university students. A Latin square design was employed. The participants did a monologue narrative task with four different types of planning: solo-written brainstorming, paired-interactive planning, teacher-led planning, and no planning. For each planning condition, 58 speech samples were analyzed totaling 232 speech samples in all. The speakers’ oral performances were audio recorded and analyzed based on the CAF (complexity, accuracy, and fluency) framework. Multivariate analysis of variance (MANOVA) results indicated that teacher-led planning and pair-work planning had a significant effect on complexity in students’ speaking performance when compared to the no-planning condition. The importance of input-mining and teachers’ roles is discussed.

本研究は、日本人大学生のスピーキングに焦点を当て、モノローグ型タスクを行う前の準備活動（pretask planning）の効果について調査した。研究参加者は29名の大学1年生である。ラテン方格デザインを用いた。モノローグ型のスピーキング・タスクを行う前に、次の準備活動を行った（個別ブレインストーミング、ペアワーク、教師主導型、準備なし）。事前準備活動ごとに、58のスピーチサンプルが分析され、合計で232のスピーチが分析された。録音された音声データは文字起こしされ、CAF指標（complexity, accuracy, fluency）に沿って分析された。多変量分散分析の結果から、学習者は、教師主導とペアワークによる事前準備活動を行うと、より複雑な文章を発することがわかった。タスクを行う前のインプットの効果とタスク活動における教師の役割について教育的な示唆を述べる。
Reexamination of Word Length Effect: Immediate Serial Recall of Foreign Words
Authors: Takeno Junichiro , Tamai Ken , Takatsuka Shigenobu
Published: February 2020

In this study we examined the word length effect—one characteristic of the phonological loop of working memory—in a foreign language. Serial position effects, such as the primacy effect and the recency effect, were observed in the recall of foreign words, similar to results in L1 studies. Recall of long (one-syllable) and short (three-syllable) words in pure (all long or all short) and mixed (long and short) lists was compared. In pure lists, there was a tendency for long words to be more poorly remembered than short words, which we considered to be because of the word length effect. In mixed lists, both long and short words were recalled equally as well as short words were recalled in pure lists. These results indicate that we should pay more attention to item distinctiveness, which elicits the attention of the central executive in working memory, as well as the word length effect in regards to rehearsal speed. Effective use of the phonological loop in listening comprehension is also discussed.

本研究は、ワーキングメモリモデルの音韻ループに見られる語長効果について再検討を試みたものである。外国語の単語記銘においても、母国語話者を対象とした研究と同じように初頭効果や新近性効果が確認された。単純リストと混合リストにおける長い語と短い語の再生率を比較したところ、単純リストでは、長い語は短い語よりも再生率が悪くなるという語長効果の傾向が見られるものの、混合リストにおいては、長い語も短い語も単純リストにおける短い語と同程度の再生率であった。これらの結果は、短期記憶容量は決められた項目数ではなく復唱速度が重要な要因であるという語長効果に基づく説明に加えて、ワーキングメモリの中央実行系に注意喚起を促す、項目の示差性などによる説明の必要性があることを示している。本研究では、聴解における音韻ループの効果的な活用についても論じている。
Effects of Preparation and Use of Keyword Lists on a Classroom Story-Retelling Test
Authors: Saito Hidetoshi
Published: February 2020

The purpose of this quasi-experimental study was to explore the effects of test practice and keyword use on story-retelling test performance under four conditions. Eighty-two beginning and intermediate Japanese university students enrolled in English courses were required to practice orally summarizing two passages using a keyword list and also instructed to orally summarize one of two previously unseen passages without preparation. In the test session, two groups experienced two conditions that were identical and one that was different. Both groups retold one practiced passage with keywords at hand and a new passage without a keyword list. Group 1 retold another practiced passage with the keyword list withheld, whereas Group 2 read an additional new passage, made a keyword list, and retold it with the keyword list but without practice. Test practice was found to improve performance, but keyword list use induced better performance only when used with practice.

テスト準備とキーワードリストは口頭要約テストに役立つか。この研究はテスト準備とキーワードリストの使用が口頭での要約テストに役立つかを調査することを目的とした。日本人大学生（初中級者）2グループ（計82名）が二つの同一条件と一つの異なる条件でそれぞれ英文要約を行った（計三条件づつ）。参加者は予め二種の英文が渡され、キーワードリストを作って練習をするように指示された。また、その場で新しい英文の要約を行うことも指示された。試験当日、両グループともまず練習した英文をリストとともに要約し、その後新しい英文の要約も行った。グループ1はさらに、準備したキーワードリストなしで練習した英文の要約を行った。グループ2はその場で新しい英文を読み、キーワードリストを作って要約を行った。結果として、練習したほうが、練習をしていない場合より良いが、キーワードリストは練習した場合のみに有効であることがわかった。
Teacher Self-Efficacy and Instructional Speech: How Teachers Behave Efficaciously in the EFL Classroom
Authors: Omote Akihiro
Published: February 2020

In this paper, I explore teachers’ self-efficacy and their instructional speech (in Japanese and English) in EFL classrooms in Japan. Mixed methods provided the framework for a questionnaire to 108 teachers followed by interviews with 6 teachers. The survey revealed a common perception that Japanese instructional speech is overused and a perceived conflict between the use of English and Japanese speech, but the interviews found that self-efficacy played a central role in a complex sociocognitive process to optimize efficacy due to distinct qualities of English and Japanese speech. Teacher self-efficacy (TSE) had two functions: an embarrassment buffer and a motivation keeper. Although both functions were conditional in English, they were cognitive and compensatory in Japanese. Along with the converging impact of English and Japanese on TSE, this discrepancy seems to lead to the overuse of Japanese in the process of efficacy optimization. Implications are provided for future instructional speech with an attempt to alleviate the conflict between the use of English and Japanese.

本研究は、教師の自己効力感（Teacher self-efficacy, TSE）を日本の英語教育におけるinstructional speech（授業言語、授業での日本語使用と英語使用）との関係から探ることを目的としている。研究は、質問紙（108名の日本人教師対象）と、その後行われた6名の教師へのインタビューを統合する混合法（mixed methods）で行われた。前者では英語と比較した日本語の過大使用、及び日英両言語の使用上の対立を、また後者では複雑で社会認知的な授業の最適化プロセスにおいてTSEが中心的役割を担っていることが判明した。TSEには問題回避と動機維持の2つの機能が見られる。しかし、英語は条件限定的、日本語は認知的または補償的にこれらの機能に関連しており、双方の関係性ははっきりと異なっていた。日本語の過大使用は、この日英言語のTSEへのそれぞれの対立的影響を元に生じていると考えられる。この対立を緩和するための授業言語のより良いあり方について考察し、いくつか提案を試みる。
Misinterpreting Japanese Student Collaboration in the L2 Classroom
Authors: Kidd Joshua
Published: February 2020

In this study, I examined points arising in L2 English activities during which Japanese students resolved to collaborate with classmates. These points included moments when students were specifically instructed to work alone, were rebuked for collaborating, or both. Of issue here was that the value and meaning ascribed by the English native speaker (NS) teachers to Japanese students’ spontaneous peer collaboration (SPC) reflected a prevailing assumption about L1 collaboration: that students were off task, were less proficient members of the class, or lacked motivation. The study explored the miscommunication that could result as students upheld what they viewed as an acceptable classroom behaviour, namely peer support through verbal collaboration, while simultaneously attempting to gain teacher recognition as competent and engaged members of the class. Candid student insights illustrated that during language-learning activities students should be given greater freedom to collaborate when and with whom they desire without fear that this will negatively impact how their performance is perceived by the instructor.

本研究は、日本人生徒が英語でのL2活動中に他のクラスメイトと協力しようとする時に生じる問題点を考察する。対象となる場面は、個人で活動するように事前に指導を受けた場合、他の生徒と協力しようとし注意された場合、その両方の場合である。ここでの問題は、日本人生徒が授業中に自発的にピア・コラボレーション(SPC)することに関し、英語母語話者(NS)の教師は、母語での共同作業では生徒は集中せず、生徒のクラス内での能力は低く、モチベーションがないと判断してしまうことだ。この研究では、生徒がクラスルーム内で許される行為だと思う事をする事によって起こるミスコミュニケーションを扱う。これらのミスコミュニケーションは、生徒が自分は有能で真剣に取り組んでいるという事を先生に理解してもらおうとすると共に、言葉を通じて協力することで得られる生徒間のサポートに関してである。生徒の率直な意見からは、外国語を勉強する為の活動中は、先生にマイナス評価をされる心配なく、生徒は自由にいつでも誰とでも協力できるべきと感じていることが分かった。
The Dynamics of Complexity, Accuracy, and Fluency: A Longitudinal Case Study of Japanese Learners’ English Writing
Authors: Hokamura Michiyo
Published: February 2020

In this study I investigated the development of complexity, accuracy, and fluency (CAF) in the English writing of 2 Japanese university students of elementary-to-low-intermediate English proficiency over the course of 1 academic year. Data were analyzed from a dynamic systems theory (DST) perspective using min-max graphs, moving correlation coefficients, and a Monte Carlo analysis. The findings show that (a) the CAF measures followed nonlinear trajectories in their development, (b) they often did not correlate positively with one another, and (c) they sometimes showed signs of improvement during phases of high intravariability. The findings suggest that to understand the developmental trajectories and processes involved in language development more deeply, cross-sectional studies of developmental trends of groups should be supplemented with longitudinal studies that examine language development in individual learners.

本研究では日本人大学生（初級から中級下レベル）二名の英文ライティングの熟達度を一年間にわたり、複雑さ、正確さ、流暢さ　(complexity, accuracy, and fluency: CAF)　の指標から調査を行った。データ分析はダイナミックシステム理論の観点から、ミニマックスグラフ、移動相関係数、モンテカルロ分析を使用して行った。その結果、(a) 両者のＣＡＦの発達軌跡は非線形であり、(b) ＣＡＦのすべてが互いに正の相関関係をとることはほぼなかった。さらに (c) 学習者個人内のＣＡＦの軌跡が大きく変動した後に発達の兆候がみられることがあった。本結果から、言語発達の軌跡やそのプロセスをさらに理解するためには、グループ間を比較する横断研究を、個々の学習者を調査する長期的研究で補完することを提案する。
Is There a Potential for a Translanguaging Approach to English Education in Japan? Perspectives of Tertiary Learners and Teachers
Authors: Turnbull Blake
Published: February 2020

Despite recent policy reforms by the Japanese Ministry of Education, Culture, Sports, Science and Technology (MEXT) emphasising a change towards a predominately target-language (TL)-based EFL classroom environment, studies have suggested that desire for L1 use by both English learners and many teachers remains prevalent in Japan. The question, then, becomes whether a resolution exists to balance the rising conflict between government policy and actual classroom practice in Japanese EFL education. The purpose of this study was to investigate the opinions of both Japanese EFL students (n = 373) and teachers (n = 261) regarding the use of the L1 (Japanese) in the L2 (English) learning process and the ensuing potential to introduce a bilingual translanguaging approach to Japanese EFL education on the whole. The findings suggest that, although there appears to be a space for a translanguaging approach to EFL education in Japan, the success would depend largely on how willing both teachers and students are to take it up and by the level of training and education provided to both sides.

英語の授業は主に英語で行われるべきだということを強調する文部科学省の政策にも関わらず、授業における日本語使用はまだ日本人学習者にも日本人教師にも好まれているという研究報告がある。これによる大きな問題は、日本の英語教育において、政府の政策と実際の授業実践の格差に解決策があるのかということだ。本論文は、第二言語（英語）を学習する際の第一言語（日本語）の使用に関する学習者（373名）と教師（261名）の意見、そしてそれに基づいたトランスランゲージングの可能性を調査した研究を報告する。分析の結果、日本の英語教育においてトランスランゲージングの可能性はあるが、その成功は学習者と教師がそれをどのように受け入れるかと両者が受ける教育と研修に大きく影響されることが示された。
Perspectives: Conceptualizing Integration in CLIL: More Than Just Learning Content and Language
Authors: Yasuda Sachiko
Published: February 2020

Content and Language Integrated Learning (CLIL) has received a considerable amount of research interest since its inception in the mid-1990s in Europe. The growth thereof has influenced various levels of English language education in Japan. Despite a recent increase in the use of this educational framework, however, a shared understanding of CLIL has yet to emerge. It appears that the term CLIL has acquired some of the characteristics associated with a brand-name that makes it simply appear to be an innovative and forward-looking educational approach. In this paper, I explore the exact nature of CLIL to advocate for the valid application of this pedagogical framework.

1990年代半ばにヨーロッパで始まった「内容言語統合型学習 (Content and Language Integrated Learning、以下CLIL)」は、近年、新しい外国語教育の枠組みとして世界中で注目を集めており、日本の英語学習環境でも、大学から中高等学校、小学校に至るまで様々な教育現場で取り入れられ始めている。しかしながら、国内で急速に拡大したCLILという概念は、いまや、斬新な外国語指導法をイメージさせる流行語のようになっており、本来のCLILの目的や理論的背景に対する正確な共通理解が構築できているとは言いがたい状況である。本稿では、「そもそもなぜ内容と言語の統合なのか」という本質的な問いに立ち返り、CLILが目指す方向性、その背景にある教育理論について整理・再考し、日本の英語学習環境への応用可能性について再検討する。

New data on species diversity of Annelida (Oligochaeta, Hirudinea) in the Kharbey lakes system, Bolshezemelskaya tundra (Russia)
Authors: Baturina Maria A. , Kaygorodova Irina A. , Loskutova Olga A.
Published: February 2020

One of the features of the tundra zone is the diversity of freshwater bodies, where, among benthic invertebrates, representatives of Annelida are the most significant component in terms of ecological and species diversity. The oligochaete and leech faunas have previously been studied in two of the three largest lake ecosystems of the Bolshezemelskaya tundra (the Vashutkiny Lakes system, Lake Ambarty and some other lakes in the Korotaikha River basin). This article provides current data on annelid fauna from the third lake ecosystem in the region, Kharbey Lakes and adjacent water bodies. The annelid fauna includes 68 species, including 51 oligochaete species, and 17 species of leeches. For each species, we give information on currently recognised classification, taxonomic synonymy, geographical distribution, findings of the species within the Russian tundra, and brief ecological characteristics.
