한국어 학습자의 메타언어 서면 피드백에 대한 오류 수정 실패 요인 분석

This paper aims to investigate the percentage of learner’s errors correction based on metalanguage written feedback provided by their instructor in Korean language writing, and also the cognitive process that they follow when integrating the feedback. Drawing upon this, the present research also aims to investigate the reasons behind the failure of feedback incorporation. A speak out aloud protocol has been followed to explore learners’ cognitive processes when they receive metalanguage written error feedback. The procedure of this study started by giving metalanguage feedback to 7 learners of Korean after a writing class. The learners were then required to review their drafts incorporating the feedback, but by verbalizing out aloud their thoughts while doing this. The result of the analysis of the written compositions and the recording of the verbalizations revealed that 1) learners corrected about 85% of their errors after receiving feedback, and that 2) reasons for not correcting errors even after receiving feedback can be grouped into the four categories of “lack of attention”, “lack of vocabulary knowledge”, “pronunciation error”, and “insufficient teacher’s explanations”. Among these, three indicates issues on the side of the learner, such as lack of attention, and that also language proficiency and an accurate pronunciation are important. Nevertheless, a further reason indicates that the teacher must provide enough content when giving metalanguage written feedback.This study approached the issue of individuating the reasons of failure of written feedback from a qualitative perspective, and we believe that it can help students in understanding feedback thus improving language proficiency.

Ontology of time and relational tense

This paper reviews some discussion on the ontology of time and investigates relevant issues of tense logic and temporal relations. It seems that most of modern tense theories are in B-theoretic terms of time, which are later/earlier than. Reichenbach’s tense theory clearly shows such characterization of tense, which is intuitive and influential, and it may be tied to our conception of time.
Thermal-Efficiency Benchmark on High-Performance Clusters

The energy efficiency of a data center depends on the cooling cost of clusters in the data center. Enhancing thermal efficiency of clusters is a practical approach to reducing energy consumption cost, optimizing scalability, and improving reliability. In this paper, we propose ThermoBench to evaluate the thermal efficiency of computing and storage clusters deployed in data centers. We shed light on the criteria and challenges of developing a thermal efficiency benchmark. We pay particular attention on clusters running scalable client-server enterprise applications in data centers. We characterize workload conditions in such a cluster computing environment in forms of client sessions of multiple requests. To resemble real-world applications, ThermoBench makes use of the TPCW benchmark to changes transaction mix and load over time. We apply ThermoBench to evaluate the thermal efficiency of a real-world cluster. Experimental results show that ThermalBench provides a simple yet powerful benchmark solution for assessing thermal behaviors of computing clusters in data centers.
Pengaruh bimbingan kelompok teknik permainan simulasi terhadap peningkatan komunikasi reseptif siswa tunarungu

&lt;p&gt;There are several problems faced by 14 deaf students as the subject of this research. They get diffiulties in understanding long sentences, connotative meaning, and they lack on vocabulary. Their inability in hearing makes them rely on their vision to gather information. Considering the reason of their difficulties, visual and attractive learning media are needed for deaf students. Group guidance on simulation game technique is a counseling guidance service that directs students to reflect daily activities in the form of games using physical media such as blue cards, OK cards and chance cards. In the group guidance of the simulation game technique, students learn to understand new vocabulary of the role played and can acquire vocabulary. The more vocabulary mastered will support students' ability to have receptive communication. To prove the hypothesis that the group guidance of simulation game technique influences the improvement of receptive communication of deaf students in SLB.B Wiyata Dharma 1, the Mann Whitney U Test analysis is used. Based on Mann-Whitney U-test Asymp Sig was obtained (2-tailed) 0.013 with an error level of 0.05 then 0.013 &amp;lt;0.05 means that Ho is rejected and Ha is accepted. It implies that the group guidance of the simulation game technique has an impact on increasing the receptive ability of deaf students. Therefore, group guidance on simulation game techniques can be used as an alternative learning media to improve receptive communication for deaf students.&lt;/p&gt;
Design and Control of a Variable Aerial Cable Towed System

Aerial Cable Towed Systems (ACTS) are composed of several Unmanned Aerial Vehicles (UAVs) connected to a payload by cables. Compared to towing objects from individual aerial vehicles, an ACTS has significant advantages such as heavier payload capacity, modularity, and full control of the payload pose. They are however generally large with limited ability to meet geometric constraints while avoiding collisions between UAVs. This paper presents the modelling, performance analysis, design, and a proposed controller for a novel ACTS with variable cable lengths, named Variable Aerial Cable Towed System (VACTS).Winches are embedded on the UAVs for actuating the cable lengths similar to a Cable-Driven Parallel Robot to increase the versatility of the ACTS. The general geometric, kinematic and dynamic models of the VACTS are derived, followed by the development of a centralized feedback linearization controller. The design is based on a wrench analysis of the VACTS, without constraining the cables to pass through the UAV center of mass, as in current works. Additionally, the performance of the VACTS and ACTS are compared showing that the added versatility comes at the cost of payload and configuration flexibility. A prototype confirms the feasibility of the system.

The increasing zoonoses threat every year, such as swine influenza, avian influenza, monkeypox, and other exotic pathogenic microbes, have caused social unrest.This unrest results in many people trying to quickly find information online as their guide to control and avoid the impact of the disease outbreak.However, there is limited digital information available online at the beginning of the outbreak.This study aims to develop a prototype of an animal disease information system as a mean of increasing public awareness towards zoonoses threats.The digital platform was developed as a smartphone application or apps.This app was called ADI 1.0 (Animal Disease Information) that contains information on animal diseases, the origin of animal diseases, the first location of the outbreak, countries with travel warrant, the first aid and casualties handling, and other related information.ADI 1.0 was designed to support and connect the government, veterinary experts, and society to provide up-to-date and real-time information.In the future, it will be linked to an early warning system, so that the users of ADI 1.0 can have a better awareness and control of a zoonosis outbreak.The developed prototype will support major media platforms in this digital era and provide necessary zoonoses information as a means of increasing social awareness
Parameter Estimation of PuRet Algorithm for Managing Appearance of Material Objects on Display Devices

In addition to colors and shapes, factors of material appearance such as glossiness, translucency, and roughness are important for reproducing the realistic feeling of an image. In general, these perceptual qualities are often degraded when reproduced as a digital color image. The authors have aimed to edit the material appearance of an image as measured by a general camera and reproduce it on a general display device. In their previous study, the authors found that the pupil diameter decreases slightly when observing the surface properties of an object and proposed an algorithm called &#x201C;PuRet&#x201D; for enhancing the material appearance based on the physiological models of the pupil and retina. However, to obtain an accurate reproduction, it was necessary to manually adjust two types of adaptation parameters in PuRet as related to the retinal response for each scene and the particular characteristics of the display device. This study realizes the management of the appearance of material objects on display devices by automatically deriving the optimum parameters in PuRet from captured RAW image data. The results indicate that the authors succeeded in estimating an adaptation parameter from the median value of the scene luminance as estimated from a RAW image. They also succeeded in estimating another adaptation parameter from the average value of the scene luminance and the luminance contrast value of the output display device. As a result of an experiment using an unknown display device that was not applied to derive the estimation model, it was confirmed that the proposed model works properly.
The data warehouse for primary geological and geophysical data: an aspect of creation

The geological industry of Ukraine as a whole is sufficiently conservative. However, the development of world scientific thought and the improvement of the mineral extraction technologies require a rethinking of primary geological data (PGD). During the Soviet times, there was a rapid development of geological prospecting activities with creation and accumulation of PGD’s large volumes. Reinterpretation and rethinking of this information using the latest techniques, approaches and technologies is an important issue. An important aspect is to save this information, because large number of PGD remains on paper. The only way to facilitate the circulation of PGD and ensure their proper storage is to create a centralized digital data warehouse using the latest information technologies for storing, processing and analyzing data. Such actions should ensure the rapid retrieval and analysis of PGD, facilitate the planning of geological prospect and ensure overall performance, including economic efficiency. The article discusses aspects of data warehouse creating for primary geological and geophysical data. The infrastructure, architecture and creating stages of the data warehouse for primary geological data are highlighted. The authors are examined the technological approaches, stages of work on the data warehouse creation. Modern technologies, including technologies associated with Big Data, are considered as those that should be oriented to performers of work. Primary geological data is partially structured or unstructured, and its volumes are constantly growing with high speed. The introduction of modern Big Data technologies will allow creating flexible powerful systems that must ensure horizontal scaling of the system in terms of computing power and storage size, and carry out operational primary processing and analysis of the data, that the user needs.

A Study on the Selection of Languages by Topic in Korean Textbooks Considering Proficiency

This study considered whether the vocabulary list of Korean level 3 textbooks is appropriate for the topics and mastery of the unit. The selected vocabulary list by topic possibly enhances the level of difficulty per unit. A list of vocabulary was chosen, based on the view of preceding studies that indicated that the words commonly included, may be essential to the topic. The study was limited to Korean level 3 textbooks published after 2010, and the vocabulary list for a total of nine types of textbooks was compiled. As a result, seven topics were commonly included in the third-level textbooks: Health, Weather, Love, Character, Travel, Job, and School Life. In this study, a vocabulary list was compiled of words that are contained in each topic. In addition, vocabulary and vocabulary lists were compared to the level of the International Standard Korean Language Curriculum that determines proficiency. As a result, select a list of vocabulary by subject , considering the requirements for mastery at level 3. The study revealed that although there are not many common vocabulary words for each topic that are suitable for Level 3 proficiency, a list of words with meaningful relevance can be selected through sub-topics. Further , it was suggested that a study of topic-specific lexemes was continuously needed to select a vocabulary that considered both proficiency and topic matter when selecting textbook vocabulary.

Speed estimation of the electric-powered wheelchair by proposing the state observer method based on experimental data

The percentage of people with disabilities (PWDs) kept increasing in each year, and the demanding usage of wheelchair is also increased. This leads to more innovation which will be focused on wheelchair such as electric-powered wheelchair (EPW) and autonomous wheelchair. The innovations of the wheelchair tend to aid the PWDs with their daily routines, and it seems more acceptable in the society. When the demand for EPW is increased, the numbers of accidents among the EPW might be increased. The objective of this study is to improve the safety system of EPW by estimating the velocity of EPW. From the velocity of EPW, the autonomous system can be embedded in the EPW in order to prevent the collision. The first phase of this study is to conduct the experiment to analyse the rotational speed of the tire during straight line and obstacle avoidance. Then, the simulation is developed to design the EPW and state observer for estimating the speed of EPW. In the modelling of EPW, the input is voltage and the output is the rotational speed of the tire. Then, the modelling is validated by comparing with the experimental results. The last phase of this study is to add the state observer in the modelling to estimate the speed of EPW. In the state observer, the experimental value from the rotational tire speed will be used as a reference and compared with the simulation. The error between the experimental and simulation value is known as estimation error, and the state observer will minimize the error to get the estimated data. By estimating the velocity of the EPW, the speed of the EPW during the cornering, obstacle avoidance and straight line could be known. The focus of this study is at first and second phases, which focus on experiments to measure the rotational speed of the tire and modelling the EPW. The results shows that the error between the experimental and simulation value is below 10%, and the modelling can be used for the state observer to estimate the speed of EPW.
