Emotion labor in teacher collaboration: towards developing emotional reflexivity
Authors: Song Juyoung , Valentine Brenda 
Published: March 2024

Abstract
This case study explores an English learner (EL) teacher’s lived experiences of emotions concerning teacher collaboration in the US. The analysis of the EL teacher’s weekly journals and the recordings of her bi-weekly meetings with a teacher educator demonstrates that the teacher experienced a great amount of emotion labor under the feeling rule of “being supportive.” The major sources of her emotion labor include (1) content teachers’ lack of training concerning ELs; (2) the lack of systematic administrative support; and (3) her perceived teacher identity. The analysis also shows how her emotional reflexivity developed through reflection and collaborative dialogue with her mentor on her emotional experiences, empowering her to take a more active role in building a professional partnership with content teachers. The article ends with implications for language teacher education and further studies on language teacher emotions.
Online English writing teaching method that enhances teacher–student interaction
Authors: Jiang Yaqiu 
Published: March 2024

Abstract
A significant component of the online learning platform is the online exercise assessment system, which has access to a wealth of past student exercise data that may be used for data mining research. However, the data from the present online exercise system is not efficiently used, making each exercise less relevant for students and decreasing their interest and interaction with the teacher as she explains the activities. In light of this, this research creates an exercise knowledge map based on the connections between workouts, knowledge points, and previous tournaments. The neural matrix was then improved using cross-feature sharing and feature augmentation units to deconstruct the workout recommendation model. The study also developed an interactive text sentiment analysis model based on the expansion of the self-associative word association network to assess how students interacted after the introduction of the personalized exercise advice teaching approach. The outcomes demonstrated that the suggested model’s mean diversity value at completion was 0.93, an increase of 0.14 and 0.23 over collaborative filtering algorithm and DeepFM (deep factor decompose modle), respectively, and that the proposed model’s final convergence value was 92.3%, an improvement of 2.3 and 4.1% over the latter two models. The extended model used in the study outperformed the support vector machine (SVM) and Random Forest models in terms of accuracy by 5.9 and 1.7%, respectively. In terms of F1 value indicator, the model proposed by the research has a value of 90.4%, which is 2.5 and 2.1% higher than the SVM model and Random Forest model; in terms of recall rate indicators, the model proposed by the research institute has a value of 94.3%, which is an increase of 6.2 and 9.8% compared to the latter two models. This suggests that the study’s methodology has some application potential and is advantageous in terms of customized recommendation and interactive sentiment recognition.

Abstract
This study presents a short communication on exploring, for the first time, a simple approach for the selective and highly effective synthesis of tricaproin by synergistically combining silicon tripolyphosphate and phosphoric acid in the catalytic esterification of glycerol with caproic acid. Results reveal that within the initial hour of the synthesis, the conversion in the presence of the proposed mixture achieved an efficiency of 62.99 %, whereas this figure for individual catalysts only modestly stopped at 27.50 and 11.74 %, respectively. Furthermore, the inherent shortcomings in the tricaprion synthesis, such as catalyst deactivation, resinification of the reaction solution, and generation of numerous by-products, were successfully addressed. The structure of the resultant tricaproin and the possible absence of undesired by-products were confirmed by NMR, mass spectrometry, FT-IR, and TLC. The optimal conditions for the synthesis were also investigated. The study not only contributes a practical and selective synthetic approach for tricaproin but also paves the way for exploring novel avenues to enhance the efficiency of the catalytic esterification.

Abstract
Photocatalysis is considered a highly promising method to treat water samples contaminated with organic pollutants. Zirconium-doped lanthanum titanate (LaTi1−x
Zr
x
O3, where x = 0 (LTO) and 0.05 (LZTO)) NPs were synthesized by the auto-combustion method and characterized by X-ray diffraction analysis (XRD), UV–visible diffuse reflectance spectroscopy (UV–vis DRS), Fourier transform infrared (FTIR), field emission scanning electron microscope (FE-SEM), and Raman spectroscopy. LTO and LZTO have tetragonal structure with an average crystalline size of 16 nm and 13 nm respectively. The band gap from UV–vis DRS was estimated to be 3.52 and 3.36 eV, respectively. The analysis of surface morphology indicates that the addition of Zr disrupted the crystal structure of LTO and transformed its spherical morphology into a rod-like structure. The Raman spectra of the LTO and LZTO crystal structure revealed the presence of A
g and B
2g symmetry phonons. The magnetic properties were analysed by vibrating sample magnetometer (VSM) which confirmed the ferromagnetic behaviour. LZTO nanoparticles have been shown to have an efficiency of 92 % after 80 min of degradation. The synthesized LZTO samples exhibited enhanced ferromagnetic behaviour and improved photoactivity for the degradation of methylene blue dye as compared to those of pure LTO, make LZTO a good choice for magnetically separable photocatalysts that effectively purify contaminated water.

The Relationship Between Sodium Consumption Patterns, Stress Levels, and Physical Activity with Hypertension of Elderly Participants at UPTD Puskesmas Rantau Tijang, Pugung District, Tanggamus Regency in 2022
Authors: Ernawati Dwi Testi 
Published: March 2024

A person with hypertension has a rise in blood pressure above the healthy range of <120/<80. The amount of sodium that the body retains can impact blood prduction. Via the sympathetic nervous system's activation, which causes blood pressure to rise intermittently, stress causes hypertension. A sufficient amount of regular exercise significantly lowers blood pressure in hypertensive individuals. Elderly people frequently experience health issues. Many of these illnesses are non-communicable diseases like high blood pressure. The Province of Lampung has a 31,9% prevalence of hypertension. According to data on hypertension in the Tanggamus district, 120,276 persons have the condition. The research objective was to determine the correlation between sodium consumption patterns, stress levels, and physical activity with hypertension in prolanis participants at the Rantau Tijang Public Health Center, Tanggamus Regency in 2022. This study used quantitative research using a cross-sectional research design. The population in this study were 63 people using the total sampling technique. Bivariate analysis in this study uses the Gamma test. The results showed a significant correlation between the level of stress and physical activity and hypertension with a p-value of 0,001 and 0,003 and no significant correlation between sodium consumption and hypertension with a p-value of 0,746.

Relevance. Today special attention is paid to potato anthocyanins as components of functional food. Increasing interest is generated by research on the use of anthocyanins for the benefit of animals and people in addition to their significant role in the life of plants. The research goal was to identify the quantitative and qualitative composition of anthocyanins in the tubers of valuable potato hybrids of Primorsky selection. Five promising potato hybrids (Solanum tuberosum L.) belonging to different groups of maturity and involved in the comparative variety testing by FSBSI “FSC of Agricultural Biotechnology named after A. K. Chaiki” were used as the research object. The research was carried out under the conditions of field and laboratory experiments in Primorsky kray, Russia, in 2018-2023. The anthocyanins were divided by the method of high-performance liquid chromatography. The anthocyanins were identified by the method of second-order mass spectrometry. Results. The research evaluated the potato hybrids for the content of anthocyanins in the tissues of the tubers – skin and flesh. The following specimens were determined to have a high content of anthocyanins both in the skin and flesh: Pri-15-12-14 (petunidin-3-arabinoside: 310.0 and 91.1 mg/kg; cyanidin-3-glucoside: 149.8 and 39.8 mg/kg) and Pri-14-52-2 (petunidin-3-arabinoside: 360.0 and 143.0 mg/kg; cyanidin-3-glucoside: 80.4 and 81.2 mg/kg). The selected specimens were characterized by purple and blue-purple skin. Genotypes Pri-14-52-2 and Pri-15-12-14 had tuber flesh with purple pigmentation. Hybrids Pri-15-12-14 and Pri-14-52-2 had the highest total content of anthocyanins in the flesh – 130.9 and 224.2 mg/kg, respectively. The conducted research identified eight different anthocyanins in the tubers of the studied potato specimens: delphinidin-3-glucoside, delphinidin-3-ramnosil-5-glucoside, petunidin-3-glucoside, malvidin-3-glucoside, cyanidin-3-glucoside, cyanidin-3-ramnosil-5-glucoside, pelargonidin-3-glucoside, and petunidin-3-arabinoside. The tubers with pink and red skin were determined to contain pelargonidin-3-glucoside. Petunidin-3-glucoside and cyanidin-3-glucoside colored tuber skin purple. The selected group of specimens might be recommended for use as functional food and in goal-oriented breeding.

Relevance. In order to expand the range of food products for the crews of the International Space Station (ISS), studies have been conducted on the specifics of developing natural flavoring vegetable additives in the form of powder for freeze-dried dishes. The aim is to evaluate new broccoli hybrids as raw materials for the production of natural flavoring vegetable additives in the form of powder for freeze-dried dishes of increased nutritional value and high degree of readiness for consumption, including components of children's, dietary and cosmonaut nutrition. Methods. The objects of the study were 6 new broccoli hybrids (2 hybrids of domestic and 4 of foreign breeding). Results. In domestic hybrids F1 (Detskiy delikates, Macho), the average vitamin C content in natural flavoring vegetable additives in the form of freeze-dried powder of a high degree of readiness for consumption was 1.66 times higher than in foreign hybrids. The highest vitamin C content was noted in the domestic hybrid children's delicacy 419.4 mg %. β-carotene was best preserved in the hybrids F1 Detskiy delikates (2.58 mg %), F1 Macho (2.56 mg %), as well as in the hybrid F1 Batavia (2.52 mg %). The amount of sugars in natural flavoring vegetable additives in the form of freeze-dried powder was on average 1.17 times higher in domestic hybrids than in foreign ones. At the same time, some foreign hybrids showed a high level of accumulation. So the largest accumulation of the sum of sugars was in the F1 Lord (12.85 %). A high level of sugar content was also observed in F1 Macho (12.84 %) and F1 Detskiy delikates (11.63 %). The F1 Fiesta accumulated the least nitrates (77.1 mg/kg). According to organoleptic indicators, the F1 Detskiy delikates has been identified. High organoleptic indices were also noted in the F1 Macho and the F1 Batavia.
