Authors: Jannah Fika Khoirotul , Asmara Candra Hadi
Published: October 2023

Teachers may have different perspectives about their roles in implementing teaching methods. One of the examples is using play-based learning. This study explores the teacher's implementation of play-based learning and the roles of Thai primary school teachers in teaching vocabulary using a play-based learning strategy. The data were collected through a qualitative case study design. Two instruments were applied in this research, online observations and interviews: 50 minutes of classroom observations held through Facebook's live streaming feature and 3 hours of individual interviews with three Thai teachers from different primary schools through the Zoom meeting platform and LINE. The finding of the observation shows that all teachers have been following aspects of the observation. Meanwhile, the finding from the interview shows that teachers' roles in play-based learning: teachers act as facilitators and leaders in the context of engagement with the students; teachers act as observers, planners, and reflectors in a reflective pedagogues context; and teachers act as communicators, advisors, and connectors for the context of partnership with student's parents. This study is expected to serve as a resource and source of information for English teachers who teach young learners so they can set some useful strategies into practice in the classroom.Teachers may have different perspectives about their roles in implementing teaching methods.

Types of spatial semantics in the ‘Cyberspace’ frame model (based on media texts in Russian)
Authors: Imamgaiazova Diana Ildarovna
Published: October 2023

The aim of the study is to identify the cognitive models and language means used to express locative semantics in the ‘Cyberspace’ frame involving the texts of Russian-language media. The study is based on the hypothesis that global news stories concerning events in cyberspace often receive a specific framing in the Russian media discourse due to both socio-cultural singularity and the peculiarities of spatial semantics expression in the Russian language. The scientific novelty of the study is determined by the fact that cyberspace representation in the mass media in Russian has not previously been the object of linguistic research, although new lexical units describing phenomena from the cybertechnology industry are being actively included both in the media discourse and in the common Russian language and require a systematic description. As a result of the study, the process of adapting the global news frame in the Russian-language media has been described for the first time taking into account lexical and word-formation models and linguocultural aspects. It has been found that the semantics of cyberspace is actualised within the framework of three thematic clusters: real, associative-background and conceptual locations described using borrowed vocabulary, authorial neologisms, metaphorisation and homonymy.

Authors: Mustholiq Mustholiq , Kensiwi Fitri , Pangestu Wisnu Ageng
Published: October 2023

A hydrophore tank or water pressure tank is a tank that stores water temporarily and then separates water and air through a membrane so that the air in it is compressed. The water in the tank is flowed into a distribution building. The pump works automatically, regulated by a pressure detector, which closes/opens the electric motor's switch driving pump. The pump stops working when the pressure in the tank reaches a specified minimum. In this system, the compressed air will press water into the distribution system. After repeatedly expanding and compressing over time, it will decrease because it dissolves in water or is carried out of the tank. Pressure tank systems are usually designed so that the air volume is no more than 30% against the volume of a 70% tank filled with water. Factors causing pressure drops in the hydrophore tank pump at MT. Inter Armada 01 is a PMS that is not carried out properly; packing is impermeable, and the fresh water pump does not work normally. The impact of the lack of pressure on the hydrophore tank is the lack of fresh water supply to the accommodation and disruption of the crew's comfort. How to prevent pressure drops on the hydrophore tank is to replace damaged components with new ones according to the manual book periodically check the components and systems of the hydrophore tank so that the hydrophore tank system can run properly and normally again. The method used in this thesis is a qualitative descriptive method with SHEL analysis techniques as a method to determine the cause and efforts to overcome it. The formulation of the problem from this study is the factors causing the lack of pressure on the hydrophore tank, the impact caused by the lack of pressure on the hydrophore tank, and the efforts that must be made to overcome the pressure drop in the hydrophore tank.

Between the cylinder wall and the cylinder block is the cylinder block is an intermediary cooling device called the primary cooling jacket of the main engine system. Here, the cooling fluid is able to draw heat away from the cylinder wall and continue its circulation. Due to an issue with the jacket cooling of the primary engine system, ship operations had to be suspended for maintenance, prompting the current investigation. The study aims to pinpoint the reasons behind jacket cooling leakage in the main engine room and suggest viable countermeasures. Observation, interviews, and reviews of relevant literature are just a few methods used to gather information. The study took a descriptive, qualitative approach, using tools like SHEL and the fishbone diagram to analyze data. According to the results of this research, a lack of attention to the planning and maintenance system for the main engine, o-ring deterioration in the jacket cooling main engine system, corrosion of the cooling jacket, rust formation in the tank, suboptimal water preheating temperature, and a lack of maintenance all contribute to leaks in the main engine cooling system. Several variables contribute to the main engine's less-than-ideal cooling efficiency. The jacket cooling system damage system's o-ring or a leak in the jacket cooling system are two examples of these problems with the primary engine system. In addition, the primary engine cooler's cooling water jacket is subpar, and its circulation is subpar. In addition, the exhaust gas temperature from the main engine is inconsistent, and rising temperatures have not yet resulted in the engine's shutoff. The primary engine system performs maintenance at the specified intervals specified in the handbook to handle problems with jacket cooling leaks. O-ring and cooling jacket replacement, chemical dosing, water pH testing, and routine temperature checks are all part of the maintenance process.

This paper addresses insufficient effort responding (IER), a significant issue in survey research affecting data quality. We focus on IER prediction through nonreactive measures and gauge its prevalence in a pupil population, leveraging a sizable online survey of adolescents. The analysis uncovers IER as a nonmarginal issue that varies considerably by gender, migration status, and school type. Utilizing Random Forest models, we evaluate nonreactive measures’ predictive power for IER, notably response time, intra-individual response variability, and Mahalanobis distance. The findings highlight the future research value of these measures, emphasizing the strong influence of response time. We also explore the relationship between predictors and IER and find that shorter response times and less response variability correspond to a greater likelihood of IER. This study illustrates the potential of nonreactive measures and advanced machine learning techniques for predicting IER and highlights the necessity for further research.

Health and safety, quality assurance, and stewardship control, when integrated together, can streamline systems and work processes, reduce bureaucracy and increase efficiency. In this study, efficiency increase refers to improving and maintaining high standards of demarcation, housekeeping, no blocked safety equipment, tools storage conditions, good manufacturing practices and chemical storage conditions. Using industrial engineering tools, Plan-Do-Check-Act and Kaizen, the study illustrates a quick turnaround in standards improvement in a manufacturing plant, which resulted in culture change and increasing profitability. The manufacturing plant studied had below average standards that created health and safety hazards leading to incidents, created a risk of quality and stewardship systems failure. Incidents varied from minor to serious. With improved standards, the plant avoided and eliminated health amd safety, quality, and stewardship risks in critical areas such as production or operations floor, warehouse, laboratory, storeroom, utilities area, and workshop. This was achieved through the integration of health and safety, quality assurance and stewardship controls as one safety, quality, and stewardship (SQS) framework. The three are denoted as fundamentals and core foundation systems in a manufacturing environment in this study. An SQS tool was developed, tested, and implemented and results are shared. Implementation of the tool resulted in improvement of overall manufacturing plant standards, elimination of safety hazards, reduction of quality defects and scrap, eradication of internal controls issues, and business success. The study will be of great value for manufacturing plants who are looking to integrate more than two management systems.

Cerebral palsy induces motor, cognitive, attention, and behavioral dysfunctions caused by brain damages. It is caused by damage to oligodendrocyte induced hypoxic ischemia and injection in the perinatal period. Therefore, an animal models that performed hypoxiaischemia-lipopolysaccharide injection (HIL) at 4-7 days of age (PND) are widely used. However, there is a difference in the brain damage due to exposure time under the hypoxic condition, gender, and ligation surgery techniques. In this paper, the optimal surgical age was found by analyzing behavioral tests, inflammatory reactions, and the differentiation and maturation of oligodendrocytes by performing HIL on rats 4, 5, 6, and 7 days old, respectively. On the 4th, 5th, 6th, and 7th days of birth (PND) of male Sprague Dawley rats, the right common carotid artery was ligated, they were incubated in an environment of 37℃, 92% N2, and 8% O2, and then peritoneally injected LPS (1 mg/kg) after removing the ligation. The rota-rod test were performed at PND 10, 20, 30, and 40, and memory tests such as passive avoidance and Morris water maze tests were performed on PND36-40, and then they were euthanized to analyze inflammatory indicators (NF-kB, TNF-a, IL-6, iNOS, and COX2) and indicators of the differentiation and maturation (Olig2, CNPase). In the case of the PND4 group, the limb coordination test were significantly different from that of the normal group, but there was no difference in other analyses. In the case of PND5 group, there were significantly differences in limb coordination tests, memory tests, inflammatory indicators, and differentiation and maturation of oligodendrocyte. In the case of the PND6 group, there was a significantly difference in limb coordination and memory tests, and a significantly increase in inflammatory indicators compared to other groups, but the mortality rate increased and indicators of the differentiation and maturation of oligodendrocyte were increased. In the case of the PND7 group, the limb coordination test showed significantly differences compared to normal group, but there was no difference from the normal group in other analyses. In conclusion, this study suggests that the PND5 group, where abnormal behavioral tests, an increase in appropriate inflammatory indicators, and a decrease in maturation and differentiation-related proteins of oligodendrocyte are comprehensively observed, is most suitable.

Orde baru berlangsung dari tahun 1968 hingga 1998, dan dapat dikatakan sebagai era pembangunan nasional. Dalam bidang pembangunan pendidikan, khususnya pendidikan dasar, terjadi suatu loncatan yang sangat signifikan dengan adanya Instruksi Presiden (Inpres) Pendidikan Dasar. Namun, yang disayangkan adalah pengaplikasian inpres ini hanya berlangsung dari segi kuantitas tanpa diimbangi dengan perkembangan kualitas. Yang terpenting pada masa ini adalah menciptakan lulusan terdidik sebanyak-banyaknya tanpa memperhatikan kualitas pengajaran dan hasil didikan.
