High quality and timely assessment feedback is central to student learning in higher education; however, written feedback has many limitations. One of the innovative approaches to delivering feedback to EFL learners is individualized audio-visual feedback (AVF) using screencast technology. Previous research on AVF has been extensively descriptive and mostly focused on student preferences for feedback and evaluation of various screencast software. The present study employed a mixedmethod design using pre-post writing tasks and pre-post questionnaires to investigate what particularly beneficial affordances this type of media-rich feedback might offer for writers in the English-Medium Instruction (EMI) classroom, to identify the effects of AVF on changes in learners’ motivation, and to explore students’ perceptions towards screencast feedback. The results suggest that AVF is positively received by EFL learners and that simultaneous visual cues and detailed explanations promote better understanding, engagement, and active listening. In addition, AVF significantly improves learners’ writing performance and academic motivation. The paper concludes with practical implications and suggestions for further research.

The Kazak honorific system has been described to consist of a number of second person forms and terms of address. In addition to these core honorific expressions, however, my recent study of spoken Kazak in the Chinese Altai reveals that there are many other politeness features — both linguistic and non-linguistic — that constitute a loosely integrated honorific register system. They include grammatical distinctions (e.g., singular/plural, past/perfect, confirmative/non-confirmative), lexical distinctions (e.g., Chinese titles/Kazak kin terms), prosody (e.g., loud/quiet, fast/slow), as well as non-linguistic features (e.g., smoking/ non-smoking, male facial hair grown/removed, serving of black tea/milk tea). This paper describes these “non-core” expressions and the semiotic processes in which they, together with the core expressions, form a dichotomous system of contrast between plain and honorific registers.

Many countries around the world have been pursuing the mission to fulfill the right to education of persons with disabilities. The usage of ICT has been well recognized internationally as essential to foster education, access to information and knowledge, and assist in the learning and teaching process. Furthermore, ICT has the great potential to ensure inclusion for persons with disabilities. The Government of Mongolia has been making efforts toward ensuring inclusion. However, the integration of ICT in schools for students with disabilities still needs further development through proper ICT policy. Therefore, this study intended to formulate the major principles of ICT Policy for improving ICT integration in education to meet the needs of students with disabilities. In this study, the content analysis of 39 academic articles from the period of 2006-2018 has been conducted in order to identify the best practices from other countries and find the applicable ones to Mongolia. As a result of this study, 7 principles have been formulated to improve ICT integration in education for students with disabilities in Mongolia.

Modern society has become an aging society, and the National Statistics Office(NSO) expects that Korea will be also an aging society by 2019, that is, people over the age of 65 will account for 14 percent from the total population. In addition, the increase of labor flexibility is also one of the dramatic features in modern society. However, this social shift have unpredictable results, that is, the advent and increase of grandparent and grandchildren family. Modern medical technology has given Koreans longer expectancies, and structural and economic changes in society have brought early retirement. One of the main reasons that grandparent and grandchildren family increase is below an average of two children per family. There are various services available such as Health support center, Dream start center, Youth support center, Community child center, and Community welfare center. Besides, schools operates various programs for grandparent and grandchildren family with social workers and school counselors. But, most of all, what is necessary is a change of perspective on them. Basically, we need to develop a clear perspective on grandparent and grandchildren family as a not dismantling family type but alternative family type with creating a separate program or service

With industrialization, environmental problems have become severe worldwide as resources are exhausted for mass production purposes and pollutants are produced in excess of nature's capacity to absorb them. Since modernity, urban parks have emerged as an important element for addressing challenges facing urban environments, which include environmental degradation. In 1987, the Brundtland Commission’s report presented a sustainable developmental perspective in solving environmental problems and provided ideas for sustainable design and sustainable urban park landscape design. The purpose of this study is to analyze sustainable design applied to Houtan Park in central Shanghai, China from the perspective of social culture preservation, ecological restoration, and economic effect, and to provide the basic data for urban park design in similar areas in the future. This study consists of a literature survey and a field investigation. The field investigation lead to analysis from three perspectives: social culture preservation, ecological restoration, and economic effect. The literature survey examined sustainable urban parks and Houtan Park based on relevant papers, newspaper articles, and reports. Through actual visits (Aug. 28 - Sep. 1, 2018), it also examined the elements of sustainable design that were applied to the architecture. The three sustainable design elements derived from this study, being a sustainable design for the future, will be used as an important basis for developing urban parks for the regeneration of brownfields in many areas in China.

Due to changes in the agricultural market environment and both overseas and domestic farming conditions, uncertainties in agricultural production and management are becoming greater. Hence, there is a stronger need for farmers to choose crops in the optimal condition. This research aims to introduce the result and process of developing a decision support system for selecting crops, aimed to assist farmers in selecting the optimal crops most suitable in the given situation. There are basically three main factors to consider in the decision-making process for farmers when selecting a crop to introduce to their lands. First of all, one must consider how much profit crop A will produce when it is cultivated. Secondly, one must consider which crop to cultivate in order to earn a certain amount of profit. Thirdly, one must consider what is the best way to maximize Farm A’s business profit. For instance, a farm may have land as its resource, and one must research which location, type of crop, level of technology, and so forth, to maximize profit.This research creates a database of the profitability of a total of 180 crop types by analyzing Rural Development Administration’s survey of agricultural products income of 115 crop types, small land profitability index survey of 53 crop types, and Statistics Korea’s survey of production costs of 12 crop types. Furthermore, this research presents the result and developmental process of a web-based crop introduction decision support system that provides overseas cases of new crop introduction support programs, as well as databases of outstanding business success cases of each crop type researched by agricultural institutions.

The study investigated the effects of recasts and prompts on learning language forms that arose incidentally in dyadic interaction, focusing on the degree of explicitness of each type of feedback and learner proficiency levels. The data were collected from 64 beginning and upper-intermediate English learners of Korean. Thirty-one beginning learners were randomly assigned to a feedback group and to a control group, and thirtythree upper-intermediate learners were also assigned to a feedback group and to a control group. Each learner was paired with an English speaker and worked on a picture-sequencing task. The learners in the feedback groups received recasts or prompts on their erroneous utterances while the learners in the control groups did not. The effects of feedback were measured by pre-interaction picture descriptions and immediate and delayed post-interaction correction tasks. The study found that both recasts and prompts had some effects on learning the targeted forms, and more explicit forms of each feedback resulted in a higher rate of correction. The beginning learners took more advantages of recasts relative to the upper-intermediate learners, and explicit prompts worked better for the upper-intermediate learners. The effects of prompts sustained longer than recasts in both levels.

Whole body fatigue detection is an important phenomenon and the factors contributing to whole body fatigue can be controlled if a mathematical model is available for its assessment. This research study aims at developing a model that categorizes whole body exertion into fatigued and non-fatigued states based on physiological and perceived variables. For this purpose, logistic regression was used to categorize the fatigued and non-fatigued subject as dichotomous variable. Normalized mean power frequency of eight muscles from 25 subjects was taken as physiological variable along with the heart rate while Borg scale ratings were taken as perceived variables. The logit function was used to develop the logistic regression model. The coefficients of all the variables were found and significance level was checked. The detection accuracy of the model for fatigued and non-fatigues subjects was 83% and 95% respectively. It was observed that the mean power frequency of anterior deltoid and the Borg scale ratings of upper and lower extremities were significant in predicting the whole body fatigued when evaluated dichotomously (p < 0.05). The findings can help in better understanding of the importance of combined physiological and perceived exertion in designing the rest breaks for workers involved in squat lifting tasks in industrial as well as health sectors.

This study investigates how sociolinguistic factors such as gender and language proficiency affect speech rhythm by examining the spoken data of 40 Korean learners of English. Prosodic rhythm, which has been perceived to differentiate various regional varieties of English from General American English, is applied to L2 speech. By using the Normalized Vocalic Pairwise Variability Index (nPVI-V; Low, Grabe & Nolan 2000), L2 speech rhythm is quantified and results indicate that nPVI-V scores are higher for advanced learners of English (indicating more stress-timed speech) than for non-advanced speakers. The effect of gender on rhythm metrics is also tested. Results show that L2 male speakers are more likely to be syllable-timed, whereas L2 female speakers more stress-timed. This may reflect an aspect of gender paradox: women are more apt to adopt the new language than men. Overall, the results of the present study disclose how sociolinguistic factors such as gender and language proficiency interact with rhythm metrics in L2 speech.

The AtoN Simulator provides simulation circumstances, which include the topographical and environmental characteristics of a primary harbor, as well as the characteristics of navigating a ship and maritime traffic. The AtoN planning expert can design a safer and more efficient distribution of AtoN using the simulator. AtoN simulation system is a system that adds AtoN part such as AtoN attribute and modeling to ship handling simulation system. AtoN 3D modeling and motion characteristics implemented in existing ship handling simulations were not perfect. Therefore, there was inconvenience in 3D simulation. Therefore, AtoN attribute construction and 3D modeling are required for AtoN simulation system. This study researched the AtoN 3D modeling for AtoN simulator. The AtoN analysis surveyed the AtoN for 3D modeling. Modeling design was designed to be similar to the actual AtoN on the basis of such an analysis of the AtoN scale. Modeling was AtoN 3D modeling based on the design drawings. Each AtoN was grouped into a Main Category and Sub Category. Specific data were easily changed using the 3D tools.

Two dimensional(2D) crystals, composed of a single layer or a few atomic layers extracted from layered materials are attracting researchers’ interest due to promising applications in the nanoelectromechanical systems. Worldwide researchers are preparing devices with suspended 2D materials to study their physical and electrical properties. However, during the fabrication process of 2D flakes on a target substrate, contamination occurs, which makes the measurement data less reliable. We propose a dry transfer method using poly-methyl methacrylate(PMMA) for the 2D flakes to transfer onto the targeted substrate. The PMMA is then removed from the device by an N-Methyl-2-pyrrolidone solution and a critical point dryer, which makes the suspended 2D flakes residue free. Our method provides a clean, reliable and controllable way of fabricating micrometer-sized suspended 2D nanosheets.

Highly self-cleaning thin films of TiO2-SiO2 co-doped with Ag and F are prepared by the sol-gel method. The asprepared thin films consist of bottom SiO2 and top TiO2 layers which are modified by doping with F, Ag and F-Ag elements. XRD analysis confirms that the prepared thin film is a crystalline anatase phase. UV-vis spectra show that the light absorption of Ag-F-TiO2/SiO2 thin films is tuned in the visible region. The self-cleaning properties of the prepared films are evaluated by a water contact angle measurement under UV light irradiation. The photocatalytic performances of the thin films are studied using methylene blue dye under both UV and visible light irradiation. The Ag-F-TiO2/SiO2 thin films exhibit higher photocatalytic activity under both UV and visible light compared with other samples of pure TiO2, Ag-doped TiO2, and F-doped TiO2 films.
