Pneumatic breakwater is a kind of wave energy damping structure which is capable of reducing a portion of wave energy. The structure utilizes an air bubble column deep in water to induce a counter flow which opposes the wave current resulting in damping of its energy and the height of the wave. Fast installation with the least space occupied along with posing no obstacle for shipping and maneuvering are advantages of this structures. Although the disadvantage of this method can be wasting of almost half the energy of outgoing air. Using this method, a range of waves with lower height can be achieved. To draw the most advantage out of this method, the pneumatic breakwater can be combined with Floating breakwater. In order to explore the effectiveness of Hybrid breakwater, a physical or numerical model in deeper water depth is required. Utilizing this method in coasts where other kind of ordinary breakwaters are not practical and temporarily in the vicinity of shore in deeper water is economically effective. This breakwater can be attached to the ship (DAHET) or rig (ATAB). Hybrid system creates a safe atmosphere for smooth transfer of the passengers of crew boats to and from wharf in a continuous manner even in rough sea and bad weather condition. Case study in Persian Gulf indicates that pneumatic breakwater is practical in Persian Gulf except for longitude between 51° and 57° and latitude between 24° and 28° Northern which extends from eastern north to 14 Kilometers of Parsian Coasts and 30 Kilometers of Lengeh Port and from western south to 6 Kilometers of Dubai coasts to Abuzabi and from eastern north to 12 km of Kargan port to Sirik and from western south to 130 Kilometers of eastern coasts of Qatar.

Published: June 2021

The study aimed at finding out the effect of students' self-regulated learning on their academic achievement in the subject of English. The study was conducted at the secondary level in the province of Punjab. It was quantitative in nature and employed a true experimental design (pre-test post-test control group). It was significant for teachers, curriculum stakeholders, training bodies, and policymakers. For the study sampling, a simple random sampling technique was used. Students' achievement test was developed for pre-test and post-test. The study sample consisted of sixty students of grade IX and they were divided into two groups; experimental and control. A pre-test was conducted on both groups to measure their current status of academic achievement. After the pre-test, the subject of English was taught to the experimental group by using self-regulated learning strategies while the traditional method (dominantly lecture method) was adopted to teach the control group. A post-test was conducted after an intervention of 16 weeks. The results of the test were compared by using a t-test. For data analysis, SPSS was used and results were interpreted accordingly. The study results revealed a significant difference between the test score results of the students. The study recommended appropriate teachers' training to use self-regulated learning strategies effectively at the secondary level.

Published: June 2021

This paper presents a novel work on localization of transmitters using triangulation with sensors at fixed positions. This is achieved when three or more sensors cover the whole area, a factor which enables the system to perform localization via triangulation. The network needs to keep a high detection rate which, in most cases, is achieved by adequate sensor coverage. Various tests using various grids of sensors have been carried out to investigate the way the system operates in different cases using a lot of transmitters. Detection complexity is tackled by finding the optimal detecting sensor radius in order the network to continue operate normally. The coverage quality changes in the area of interest and the network is able to detect new transmitters that might enter it's area. It is also shown that as the number of transmitters increases the network keeps its high performance by using additional groups of sensors in a sub-region area of that of interest. This way, even when the network is saturated by many transmitters in one region, new transmitters can still be detected.

Acute toxicity testing is a commonly accepted procedure for preclinical testing of the safety of potential drugs. The compound GIZh-290, which is a derivative of 4-phenylpyrrolidone– 2,6 - dimethylanilide (2-oxo-4-phenylpyrrolidine-1-yl) acetic acid and has a nootropic and anticonvulsant effect, was studied. The results obtained after a single oral and intraperitoneal administration to mice allow us to attribute GIZH-290 to the 4th class of toxicity – "lowtoxic substances". The study revealed the neurotoxic effects of GIZH-290, which may be due to the main pharmacological activity of the compound used in sublethal doses.

Authors: Gibbon Ben , Nakagawa Yuya
Published: June 2021

The quantitative case study investigates whether Freeman’s (1989) K.A.S.A teacher framework is effective when adjusted for student use during self-reflection tasks. The potential of this teaching method to improve learner study skills, namely to scaffold learner autonomy, will be considered. This paper offered a framework to 30 students as an autonomous self-assessment task, their answers were analysed using KH Coder 3, a text-mining software, to quantitatively identify clusters of lexemes expressed by participants to determine whether they had cited the framework’s dimensions of knowledge, attitude, skills, and awareness. A notable observation is that students demonstrated agency through complex metacognitive engagement with the reflection tool, evidenced by clear proximities co-occurring between awareness and skills. Word-trees were mapped to further assist the exploration of co-occurring themes and implicated that this tool may aid students with the process of identifying personal skill proficiencies; potentially assisting learners to map their learning experiences with more nuance.

Authors: Nakachi Kento
Published: June 2021

A fruitful discussion on language learning strategies has taken place in the field of second language research. However, little is known about grammar learning strategy (GLS) use (Pawlak, 2013, 2018, 2020). The present study explores GLS utilized by 145 English-major university students with Grammar Learning Strategy Inventory (GLSI), a data-collecting instrument developed by Pawlak (2018, 2020). In addition, the current study examines TOEIC scores extracted from 27 student participants to investigate if there is any correlation between GLS use and TOEIC scores. The descriptive data analysis revealed that cognitive strategies used when coping with corrective feedback were the most commonly utilized strategies while affective strategies were the least. Furthermore, the correlational analysis demonstrated that five strategies from metacognitive, cognitive, and affective GLS showed a weak-to-moderate correlation with TOEIC scores (p < .05). The present study concludes with an emphasis on strategy instruction and the necessity of further investigation using GLSI.

Second Language Creative Writing: Learner Development in the Shinhaiku Pedagogy
Authors: Kubokawa Jared
Published: June 2021

This article will address the place of second language creative writing (L2CW) in EFL curricula by first providing an updated understanding of L2CW and the Japanese form shinhaiku—a nontraditional haiku. Shinhaiku differs from traditional haiku in that it does not utilize the 5-7-5 syllable form. Secondly, the article will consider misconceptions as well as pedagogical implications of L2CW and thirdly, offer a classroom approach to L2CW (poetry writing) utilizing Hanauer’s (2012) meaningful literacy framework. The approach was developed from action research and teaching practices, underpinned by Spiro’s (2014) reading-to-writing cycle where learners 1) choose L2CW poems that they admire from an EFL literary journal; 2) articulate reasons for appreciation of said poems; 3) apply these ideas to their L2CW; and 4) reflect on the process. The article will also provide examples from student work as well as present a case for why shinhaiku is an accessible form in the Japanese context.

この論文は、EFLの履修に於ける第二言語のクリエイティブライティング(L2CW)の位置付けについて述べたものである。第一に、L2CWの最新の解釈と日本語の形式として新俳句（従来型ではない俳句）を提示する。新俳句は形式として五七五の音節を使わないという点で、従来の伝統的な俳句とは異なる。次に、L2CWの誤認と教育法への影響について考察する。続いて、Hanauer (2012)による「意味を持つ読み書き能力の教育法」を通してL2CWの授業での取り組み（詩の創作）について述べる。この考え方はSpiro (2014) のreading-to-writing cycle (2014)に実証された行動研究と教育方法を発展したものである。その方法では、学習者は、1) EFL literary journal から彼らが良いと感じるL2CWの詩を選ぶ 2)前述の詩を良いと思う理由を明確化させる 3) その考えを自分のL2CWに応用させる 4)その過程を振り返り考察する。そして、学生の作品を例示し、新俳句が日本において利用し易い形式である理由を論証する。

Published: June 2021

Meta-analysis is a powerful and important tool to synthesize the literature about a research topic. Like other kinds of research, meta-analyses must be reproducible to be compliant with the principles of the scientific method. Furthermore, reproducible meta-analyses can be easily updated with new data and reanalysed applying new and more refined analysis techniques. We attempted to empirically assess the prevalence of transparency and reproducibility-related reporting practices in published meta-analyses from clinical psychology by examining a random sample of 100 meta-analyses. Our purpose was to identify the key points that could be improved, with the aim of providing some recommendations for carrying out reproducible meta-analyses. We conducted a meta-review of meta-analyses of psychological interventions published between 2000 and 2020. We searched PubMed, PsycInfo and Web of Science databases. A structured coding form to assess transparency indicators was created based on previous studies and existing meta-analysis guidelines. We found major issues concerning: completely reproducible search procedures report, specification of the exact method to compute effect sizes, choice of weighting factors and estimators, lack of availability of the raw statistics used to compute the effect size and of interoperability of available data, and practically total absence of analysis script code sharing. Based on our findings, we conclude with recommendations intended to improve the transparency, openness, and reproducibility-related reporting practices of meta-analyses in clinical psychology and related areas.

The importance of mine site mapping information aims to prevent landmines from being a feeding weapon for the NAVY's Alutsista. In realizing a mine-site mapping and location system that can provide geo-location information for mines using Arduino devices. Build your exercise Smart mine positioning using Global Positioning System (GPS) Neo-M6. A study in providing latitude and longitude location information is packaged using a GPS module that is connected to the Arduino processing device to obtain the location coordinates of the latitude and longitude mines. Test results of GPS-based location tracking devices are obtained by the results of location data in latitude and longitude formats. Smart Mine location identification, can be applied using GPS based on the results of the design and creation of the system that has been done. Location displacement speed calculations can be obtained by calculating the starting location with the updated location in a time span and converting to a unit of distance. Based on the results of the speed test can be obtained even if the device's location position is unchanged, this is due to the GPS data always changing due to the level of position accuracy obtained from satellites. The use of the Neo-M6 GPS can be applied to the latitude and longitude location identification systems acquired a relatively small error value with an average satellite number obtained by as much as 8 satellites. The use of the Neo-M6 GPS, to get GPS data from satellites is a long time, the problem of GPS gets satellite data due to the less supportive weather conditions.

Support the presence of the KRI elements it needs other supporting means such as Fasharkan (Maintenance and repair facilities) that serve as a supporter of logistics, especially repair and maintenance of KRI. The closest area of Fasharkan from the Sea of North Natuna today is Fasharkan Mentigi Lantamal IV Tanjung Pinang is approximately 510 Nm surely will be an obstacle when the presence of the KRI element in the North Natuna Sea operating area is shaken because The distance of Fasharkan from the distant waters of North Natuna to carry out maintenance and repair. So it is necessary to one more location of Fasharkan to support the operation of the KRI elements in the territorial waters of North Natuna so that the operation of the KRI elements can be carried out well. In the selection of Fasharkan location has several factors that must be considered so that categorized have multicriteria in the election. So to accommodate Multicriteria divided into Technical Requirements & Operational Requirements Then use the Fuzzy method MCDM (Multi-Criteria Decision Maker). Technical Requirement consisting of earthquake hazard, distance field operations (distance operations and ALKI 1), distance downtown (the distance of the center of the government and the settlement), and hydrography (depth, tidal, and speed of currents). While the Operational Requirement consists of the influence of other countries, threats (outside state threat and community conflicts), access transportation (military port and airport), supporting facilities (water facility, communication facilities, Electric facilities, transport facilities and sea flows), as well as operational costs. For the alternative location of Fasharkan consists of Lantamal XII Pontianak, Ranai Navy Base, and Tarempa Navy Base.Of the three alternative locations obtained the best alternative to the location of Fasharkan is Ranai Navy Base with the highest rank of 0.403 then Lantamal XII Pontianak with a value of 0.302 and Tarempa Navy base with a value of 0.295.

The Indonesian Navy is a unit of defense of the Republic of Indonesia (NKRI). Sea mines are explosive devices placed in waters to destroy ships. Acoustics is a branch of physics that deals with all mechanical waves in liquids, gases and solids, such as vibration, sound and ultrasonic. Arduino has made microcontroller technology more accessible and easier for even novice users. Because of this, there are special functions in audio or acoustic processing techniques aimed at using Arduino. The application of acoustic signals in the military field of the Navy, in the identification of vessels caught by the microphone receiver. The movement of objects that are caught by the microphone will be analyzed to conclude the object. From the results of the sound characteristics raised by the object, it will give a different picture for different variations of the object. Processing acoustic signals using DSP will make it easier to infer the captured acoustic signal. The circuit board used is a microphone signal amplifier and signal conditioner, for processing the audio signal obtained from the microphone and to produce output data which is the result of the process using Arduino. Analog-to-digital converter (ADC) of the microcontroller works in the voltage range from 0.0 V to +3.3 V or +5.0 V. Toachieve good sampling results, that the signal peak is close to the maximum value of the ADC.  Additionally, voltage amplitudes above this threshold can damage the controller input port or produce unwanted harmonics. Therefore, a signal pre-amp circuit is needed to guarantee the appropriate audio sample signal as well as to protect the system. The test results obtained from the system analyzer frequency and signal meters can be used to identify acoustic signals.
