Published: July 2023

IntroductionStudents who use spherical video-based virtual reality (SVVR) teaching materials for learning are able to gain more self-regulated, explorative, and immersive experiences in a virtual environment. Using SVVR teaching materials in art courses can present diverse and unique teaching effects, while also leading to the emergence of students’ flow states.MethodsTherefore, through an art course teaching experiment, this study investigated 380 high school students and used structural equation modeling to analyze the antecedents and outcomes of students’ flow state in using SVVR teaching materials.ResultsThe results show that in using SVVR teaching materials in art courses, more attention should be paid to the control and telepresence in the antecedents of students’ flow state.DiscussionOnly when they obtain better flow experiences can they have higher perceived usefulness and satisfaction with the content of the art course, as well as stronger intentions to continue using it. These results can provide a reference for the development and use of SVVR teaching materials in high school art courses.

ObjectiveAlcohol use disorder (AUD) is a common mental disorder characterized by repeated withdrawal episodes. Negative emotions during withdrawal are the primary factors affecting successful abstinence. Oxytocin is a critical modulator of emotions. OXTR, the oxytocin receptor, may also be a promising candidate for treating alcohol withdrawal symptoms. Previous studies indicated that people with different genotypes of OXTR rs2254298 were reported to suffer from more significant depressive or heightened anxiety symptoms when experiencing early adversity. The present study aims to explore the modulatory role of the polymorphism OXTR rs2254298 on mood disorders during alcohol withdrawal and to help researchers better understand and develop effective relapse prevention and interventions for alcohol use disorders.MethodsWe recruited 265 adult Chinese Han men with AUD. Anxiety and depressive symptoms were measured using the Self-Rating Anxiety Scale and Self-Rating Depression Scale. Alcohol dependence levels were measured using Michigan Alcoholism Screening Test. Genomic DNA extraction and genotyping from participants’ peripheral blood samples.ResultFirst, a multiple linear regression was used to set the alcohol dependence level, OXTR.rs2254298, interaction terms as the primary predictor variable, and depression or anxiety as an outcome; age and educational years were covariates. There was a significant interaction between OXTR rs2254298 and alcohol dependence level on anxiety (B = 0.23, 95% confidence interval [CI]: 0.01–0.45) but not on depression (B = −0.06, 95% CI: −0.30 – 0.18). The significance region test showed that alcohol-dependent men who are GG homozygous were more likely to experience anxiety symptoms than subjects with the A allele (A allele: β = 0.27, p &lt; 0.001; GG homozygote: β = 0.50, p &lt; 0.001). Finally, re-parameterized regression analysis demonstrated that this gene–environment interaction of OXTR rs2254298 and alcohol dependence on anxiety fits the weak differential susceptibility model (R2 = 0.17, F (5,259) = 13.46, p &lt; 0.001).ConclusionThis study reveals a gene–environment interactive effect between OXTR rs2254298 and alcohol withdrawal on anxiety but not depression. From the perspective of gene–environment interactions, this interaction fits the differential susceptibility model; OXTR rs2254298 GG homozygote carriers are susceptible to the environment and are likely to experience anxiety symptoms of alcohol withdrawal.

BackgroundAlthough international research-based literature from the last 2 decades seems to favor the use of medical cannabis (MC), there is a lack of evidence concerning healthcare students’ education on MC in the Republic of Cyprus and across the world. Therefore, this study explores healthcare students’ attitudes, beliefs, and knowledge regarding the use of MC. We paid special attention to differences across specific sociodemographic (gender, age, and religion status) and educational (level of study and study field) characteristics.MethodsA descriptive cross-sectional study was conducted between November 2019 and March 2020. All active undergraduate and postgraduate healthcare students (nurses, physiotherapists, speech therapists, pharmacists, and occupational therapists; N = 900) studying in public and private universities in the Republic of Cyprus were eligible to participate (final sample: N = 819, response rate = 91%). To collect data on the attitudes, beliefs and knowledge of the participants, we used the Medical Cannabis Questionnaire (MCQ). To analyze the data, we employed the Pearson’s chi-square test for group differences, in addition to assessing the descriptive and inferential statistics.ResultsApproximately 82.2% believed that MC education should be integrated into the clinical practice requirements. Statistically significant differences were observed between genders in terms of beliefs/risk associated with the use of MC, with males being more likely to believe that there are significant mental-health benefits associated with using ΜC compared to females (84.9% vs. 76.2%, p&lt;0.05). Females were more likely than males to believe that using MC poses serious physical (76.8% vs. 60.6%, p&lt;0.001) and mental-health (77.9% vs. 66%, p&lt;0.001) risks. Moreover, participants who received formal education about MC during their study/training were more prepared to answer patient/client questions about ΜC (p &lt; 0.001). In addition, participants who received formal education had more frequently friends (p &lt; 0.001) or family members who used MC (p &lt; 0.005).ConclusionThis study provides useful information for curriculum development, educational changes, and policy decisions related to cannabis use for medical purposes in the Republic of Cyprus. The results showed that the majority of the healthcare students who participated in the study favored MC use. However, the participants reported a lack of knowledge and recommended additional evidence-based research and education to enhance their knowledge about MC use. Therefore, we recommend the implementation of formal education on MC among healthcare students in the Republic of Cyprus during their study and clinical training. Furthermore, it is important to include MC-related theoretical and clinical/laboratory courses during studies and clinical practice.
Education level as a predictor of the onset of health problems among China’s middle-aged population: Cox regression analysis
Authors: Ping Ruru , Oshio Takashi 
Published: July 2023

BackgroundDespite the importance of midlife with reference to one’s health, educational inequalities in midlife health have attracted little attention in China. Using Cox proportional hazards regression analysis, this study examined the association between educational attainment and the onset of midlife health problems and investigated the potential mediating effects of socioeconomic position (SEP) other than educational attainment, depression, and health behavior.MethodsData were extracted from the China Health and Retirement Longitudinal Survey (CHALRS) from 2011 (baseline) to 2018 (latest data). Participants aged 45–59 years at baseline were studied (N = 8,050). Health outcomes included the onset of poor self-rated health (SRH), limitation in activities of daily living (ADL) and instrumental ADL (IADL), multimorbidity, hypertension, dyslipidemia, heart diseases, and stroke over the 7-year follow-up period. Cox proportional hazard models were used to examine the associations of the outcomes with educational attainment, while controlling for potential mediators (other SEP, depression, and health behaviors).ResultsLower educational level was associated with increased incidences of poor SRH and ADL/IADL limitations, but with decreased incidences of dyslipidemia and heart disease. After adjusting for baseline covariates, the RII was 2.17 (95% confidence interval [CI]: 1.74, 2.70) for poor SRH, 2.15 (95% CI: 1.42, 3.26) for ADL limitation, 3.84 (95% CI: 2.98, 4.94) for IADL limitation, 0.52 (95% CI: 0.40, 0.68) for dyslipidemia, and 0.55 (95% CI: 0.40, 0.74) for heart disease. Significant proportions (2.1 to 27.0%) of the RII were explained by the mediators. No sex or urban–rural differences were found in this study.ConclusionOur findings suggest that educational attainment is an important predictor of the incidences of key midlife health problems, with significant mediating effects exerted by other indicators of SEP, depression, and health behavior.
The impacts of low-carbon city pilot policies on natural population growth: empirical evidence from China’s prefecture-level cities

Published: July 2023

IntroductionThe carbon emissions that cities contribute drive the development of low-carbon cities (LCCs) and low-carbon city pilot (LCCP) policies. However, the lack of comprehensive understanding regarding the impacts of LCCP policies on natural population growth hampers effective policy design and implementation, thus constraining sustainable development at the city level.MethodologyExtending the existing papers which focus on the relations between low-carbon pilot policies and industry transformation or economic growth, this research applies several experimental methods [e.g., Propensity Score Matching-Difference in Differences (PSM-DID)] to investigate the impacts of low-carbon pilot policies on natural population growth by applying the data from 287 prefecture-level cities in China from 2003 to 2019.Results and DiscussionThis research found that low-carbon pilot policies would positively influence the low-carbon cities’ natural population growth by influencing (a) economic factors, (b) political factors, (c) technological factors, and (d) the living environment. This research establishes a framework for understanding the impact mechanisms of LCCP on natural population growth. This paper investigates how industrial structure optimization, policy design and implementation in different regions, technological innovations, and urban green space theoretically affect natural population growth. This paper also proposed characteristics of LCCP which should be theoretically concerned by the government. From a practical perspective, this research suggests several policy recommendations. Central and local governments are encouraged to prioritize industrial structure optimization and assess populations’ dependence on cultivated land. Providing additional policy support to underdeveloped areas is crucial to promote the balance between economic and environmental development. Furthermore, establishing online public health platforms and urban green spaces is proposed to enhance the population’s health and complement the implementation of LCCP policies. This offers both theoretical and practical insights into the impacts of LCCP policies on natural population growth. Its findings contribute to designing and implementing LCCP policies in China and other developing countries at a similar development stage.

The present study proposes a rapid cooling method based on vacuum spray cooling, and establishes an experimental system to study the cooling performance of this method by taking tofu as an example. In this study, the effects of vacuum spray cooling, vacuum cooling and immersion vacuum cooling on the cooling rate, water holding rate, PH, TPA and other properties of tofu were compared. The total cooling time of vacuum spray cooling (13.86 min) was shorter than that of immersion vacuum cooling (33.39 min) but longer than that of vacuum cooling (10.64 min) for a temperature decrease from 70°C to 4°C. For weight loss from 70°C to 4°C, vacuum spray cooling (2.96%) was significantly less than that of vacuum cooling (10.21%). The PH value after cooling has no significant difference, but the color difference and water holding capacity of the sample after vacuum spray cooling are obviously better. However, the textural properties of the sample cooled by vacuum spray cooling were close to (for elasticity and viscosity) and better (for hardness and chewiness) than those of immersion vacuum cooling. In addition, compared with the two cooling methods in terms of storage, vacuum spray cooling can effectively maintain the moisture content, water holding rate, PH, chromatism and TPA of tofu, thus extending the fresh-keeping period of tofu. The conclusions of this paper provide theoretical support for prolonging the preservation period of food and optimizing the cooling process.
Evaluating wrapping alpine ski boots during on-snow carving
Authors: Honert Eric C. , Harrison Kathryn , Feeney Daniel 
Published: July 2023

IntroductionAlpine ski boots enable rapid and precise force transfer between skier and ski while carving. These boots are made of rigid plastic and fit tightly commonly through four buckles. Such a fit can improve speed and control but also pain and discomfort. In athletic footwear, alterations to the upper designed to wrap the foot improve performance during rapid changes of direction and during trail running. The purpose of this study was to systematically evaluate the performance and fit of two different ski boot shell closure mechanisms: a BOA closure and a Buckle closure.Materials and methodsThis was a two-part study with 22 subjects performing on-mountain skiing and 10 of those subjects completing an in-laboratory pressure evaluation. Subjects skied in both boots three times each while data from inertial measurement units (IMUs) and plantar pressures were collected along with subjective data. In lab, static dorsal and plantar pressures were collected while the subjects flexed into the boots.ResultsThe BOA boots improved subjective and objective ski performance; qualitative carving scores were greater, likely through increasing the amount of normal force applied to the ski while turning. There were no differences in edge angles between the boots, as computed from IMUs. The BOA boot also reduced static peak plantar pressures in the rearfoot along with reducing overall static pressure on the dorsum as compared with the Buckle boot.ConclusionsThis is the first study to systematically evaluate differences in ski boot closures. The improvements in carving performance in the BOA boot are supported by distinct differences in pressure distribution within each boot, which we speculate contributed to improved performance by reducing discomfort or pain while still facilitating effective force transfer.

Published: July 2023

"Regarding the Call of Jonah" is a simple study conducted by the author on two Christian groups from different ethnic backgrounds in interpreting the text of Jonah. The ethnic groups referred to here are the Torajanese and Ambonese. In this study, the author employed intercultural hermeneutics as a method to observe how both groups understand the text of Jonah based on their backgrounds as Ambonese and Torajanese individuals as theology students. Through this method, the author also aimed to examine the extent to which intercultural readings could be conducted with these two groups, as well as the transformations that could be achieved through intercultural interpretation. The study found that both the Torajanese and Ambonese groups had interpretations of the text influenced by their specific theological education and ethnic background as readers. Although the intercultural readings were still relatively simple, they were considered favorable, as evidenced by the exchange of interpretations that solidified each group's understanding and the acquisition of new perspectives. Thus, the study's transformation was achieved through a positive response to the readings of the other group.
“Menyoal Panggilan Yunus” merupakan penelitian sederhana penulis terhadap 2 kelompok Kristen dengan latar belakang suku yang berbeda dalam membaca teks Yunus. Suku yang dimaksud di sini adalah suku Toraja dan Ambon. Dalam penelitian ini penulis menggunakan metode hermeneutik interkultural untuk melihat bagaimana kedua kelompok memahami teks Yunus berdasarkan latar belakang mereka sebagai orang Ambon dan orang Toraja yang merupakan pelajar Teologi. Melalui metode ini penulis juga mau melihat sejauh mana pembacaan interkultural dapat dilakukan terhadap dua kelompok ini serta transformasi seperti apa yang diperoleh melalui pembacaan interkultural. Dalam penelitian ini diperoleh bahwa baik kelompok Toraja maupun Ambon memiliki pemahaman terhadap teks yang dipengaruhi oleh latar belakang mereka sebagai individu yang belajar teologi secara khusus serta suku pembaca. Pembacaan interkultural yang dilakukan walaupun masih sangat sederhana namun sudah termasuk kategori baik yang nampak dari hasil pertukaran pembacaan yang membuat masing-masing kelompok merasa diteguhkan dengan adanya pembacaan dari kelompok lain serta adanya perspektif baru yang diperoleh. Dengan demikian tranformasi dalam penelitian dapat tercapai melalui respon positif terhadap hasil pembacaan kelompok lain.

Buah dan sayur merupakan komponen diet yang sangat penting bagi manusia untuk mencegah berbagai penyakit kronis. Produk segar dapat mengalami beberapa jenis stres selama dalam penanganan. Umumnya gejala stres tidak mempengaruhi keseluruhan kualitas produk, namun akan semakin jelas terlihat seiring dengan penurunan kualitas produk. Kerugian ini merupakan dampak dari kerusakan fisik, stres karena pelukaan atau infeksi laten yang disebabkan oleh jamur atau bakteri yang dimulai sejak masa pra panen. Kebanyakan negara berkembang berada di daerah tropis yang menyebabkan sistem penanganan produk hortikultura dipengaruhi oleh tingginya suhu dan kelembaban. Di negara-negara miskin, kehilangan hasil selama rantai pemasaran dapat mencapai hingga 50%. Mengganti penggunaan fungisida sintetik dengan produk alam (umumnya yang berasal dari ekstrak tanaman) yang tidak beracun dan memiliki cara kerja yang spesifik semakin mendapatkan perhatian saat ini. Senyawa alami yang diproduksi oleh buah selama masa pematangan telah menunjukkan potensi yang cukup tinggi untuk digunakan sebagai pencegahan serangan busuk oleh patogen Kata kunci: Buah dan sayur; Ekstrak alami; Penyakit pasca panen

Authors: Susanti Desi , Rahmi Suci 
Published: July 2023

ABSTRAKTongkol jagung merupakan bahan yang cukup potensial dimanfaatkan sebagai substrat sumber energi dalam memproduksi enzim selulase melalui proses fermentasi. Hal ini dapat dilihat dari kandungan nilai gizi tongkol jangung sebagai berikut : 391 gr selulosa, 421 gr hemiselulosa, 91 gr lignin, dan 17 gr protein. Namun demikian selulosa dan hemiselulosa pada tongkol jagung belum optimal kerjanya dalam menginduksi produksi enzim selulase, karena rendahnya kandungan nitrogen sebagai pendukung pertumbuhan kapang. Blondo merupakan salah satu bahan yang dapat dijadikan sebagai substrat sumber nitrogen dalam medium fermentasi, karena kaya akan kandungan protein kasar sebanyak 24.22%. Penelitian ini bertujuan untuk mengetahui pengaruh komposisi substrat (tepung tongkol jagung (TTJ) dan blondo (B) dan lama fermentasi oleh Trichoderma Harzianum dalam memproduksi enzim selulase. Bahan utama yang digunakan dalam penelitian ini adalah tepung tongkol jagung, Blondo, PDA, isolat Trichoderma Harzianum, Reagen Nelson I dan Nelson II dan Fosfomolibdat. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) pola Faktorial 3 x 3 dengan 3 ulangan. Perlakuan yang diberikan yaitu komposisi substrat campuran tepung tongkol jangung (TTJ) dan blondo (B) dengan perlakuan B1 (80% TTJ+ 20% B), B2 (70% TTJ+ 30% B) dan B3 (60% TTJ+40% B) dan lama fermentasi (C) dengan perlakuan C1 (5 Hari), C2 (7 hari) dan C3 (9 hari). Data hasil penelitian dianalisis dengan menggunakan analisis ragam (ANOVA) dengan taraf signifikasi 5%. Variable yang diamati adalah aktivitas enzim selulase. Hasil penelitian menunjukkan bahwa perlakuan komposisi substrat 70% tongkol jagung dan 30% blondo dengan lama fermentasi 7 hari berpengaruh nyata (P<0.05) terhadap aktivitas enzim selulase.Kata Kunci : Tongkol jagung, blondo, Trichoderma harzianum, aktivitas enzim selulase
