Objectives. To compare the short- and long-term hearing outcomes after successful inlay cartilage tympanoplasty between patients with small (≤25%) and large (≥50%) eardrums perforations. Methods. This is a retrospective case series study conducted in a tertiary referral center. Twenty-five patients who underwent 27 procedures were enrolled. Their mean age was 60.26 years (range, 42 to 76 years). The mean follow-up time was 18.86 months (range, 12.30 to 35.83 months). The preoperative, initial postoperative, and long-term hearing results in patients with total repair of the eardrum were analyzed. Results. In the small size group, the average (±standard deviation) air-bone gap (ABG) closure was 1.08±7.53 dB in the short-term and 2.33±11.56 dB in the long-term hearing examinations. There was no difference between short- and long-term ABG closure (P=0.689). In the large size group, the average ABG closure was 9.77±9.40 dB in the short-term and 16.25±6.01 dB in the long-term hearing examinations. There was a significant difference between short- and long-term ABG closure (P=0.029). Conclusion. Patients with large perforations have continuous hearing improvement and ABG closure for more than one year. In contrast, the short- and long-term postoperative ABGs are almost the same in patients with small perforations. More long-term postoperative follow-up of hearing results is necessary for large perforations.

This critical analysis essay investigates the recent trends and issues of Early Childhood Education (ECE) in Singapore by triggering a cosmopolitan outlook for the future. Trends are introduced by reviewing recent government initiatives. Issues are examined by analyzing and incorporating the related scholarly studies and my exploration of teachers’ reflections about such changes. The critical analysis is made with multiple discourses to interpret trends and issues in Singapore. These trends include inquiry-based learning, child-centeredness, and teachers as reflective thinkers. The issues consist of teachers’grappling to adapt to the local traditions of efficiencyand standardized-oriented education for the global trends. The future landscape argues for adopting cosmopolitanism, instead of being “universalized” in a narrow way (which is standardized and homogenized by the worldwide views; usually dominated by the western perspectives only). In globalization, cosmopolitanism prevails in both a local context and foreign cultures through emphasizing education as an evolving process to uphold the local traditions and be open to the new possibilities. A cosmopolitan outlook including a cosmopolitan teacher and cosmopolitan ECE is argued and proposed for the future landscape by drawing upon Hansen’s (2010), Luke (2004), and Popkewitz’s (2003, 2007) works.

The crystallization behaviours of nanocomposite made by a function of quenching rate (roller speed) were studied. The results showed that there was one step crystallization process for the alloy quenched at roller speed of 32 ㎧, which could be shown as, Am (amorphouse) + α-Fe+Nd₂Fe₁₄B → α-Fe+Nd₂Fe₁₄B. For the alloy quenched at roller speed of 40 ㎧, there was two steps crystallization process taking place at different temperatures, which could be shown as, Am → α-Fe+Nd₂Fe₂₃B₃+Nd₂Fe₁₄B+Am' → α-Fe+Nd₂Fe₁₄B. The presence of transition phase (Nd₂Fe₂₃B₃) was harmful to get fine and uniform grain size during crystallization process. Uniform microstructures and high magnetic properties could be attained for the as-quenched alloy containing less amorphous phase and no presence of transition phase during annealing treatment. For the alloy prepared at roller speed of 32 m/s, the following properties were obtained, Br = 0.904 T, iHc = 801 ㎄/m, (BH)max = 122 kJ/㎥ and Mr/Ms = 0.6.

In this study, a system for monitoring orchard environments was developed using long range (LoRa) communication technology, where environmental data were captured and analyzed remotely to establish an orchard environment database and achieve the goals of orchard environmental monitoring and early warnings. Because pear quality is susceptible to the effects of climate change, to prevent them from sustaining damage, an environmental monitoring system was constructed in three orchards in Yilan County’s Sanxing Township, Taiwan. Sensors were used to monitor various environmental data including temperature, humidity, illuminance, soil temperature, soil moisture, and wind speed. An Arduino Uno control interface card was used to collect sensor data, which were transmitted to a LoRa Gateway as well as to the message queuing telemetry transport protocol using LoRa wireless communication modules. Integrate environmental data into an orchard data database for fruit farmers to promptly understand the growth situation of their shangjiang pears, perform effective detection and analyses, and implement a crop cultivation early warning system as well as corresponding contingency plans. This study elevated the stability of outdoor environmental monitoring stations, ensured that equipment such as sensors could collect outdoor environmental data for an extended period of time, and integrated environmental parameters monitored before performing subsequent investigations.

Candida albicans is amajor fungal pathogen in humans. Antimicrobialpeptides (AMPs) are critical components of the innateimmune response in vertebrates and represent the firstline of defense against microbial infection. LL-37 is the onlymember of the human family of cathelicidin AMPs and iscommonly expressed by various tissues and cells, includingsurfaces of epithelia. The candidacidal effects of LL-37 havebeen well documented, but the mechanisms by which LL-37kills C. albicans are not completely understood. In this study,we examined the effects of LL-37 on cell wall and cellular responsesin C. albicans. Using transmission electron microscopy,carbohydrate analyses, and staining for β-1,3-glucan,changing of C. albicans cell wall integrity was detected uponLL-37 treatment. In addition, LL-37 also affected cell wallarchitecture of the pathogen. Finally,DNAmicroarray analysisand quantitative PCR demonstrated that sub-lethal concentrationsof LL-37 modulated the expression of genes witha variety of functions, including transporters, regulators forbiological processes, response to stress or chemical stimulus,and pathogenesis. Together, LL-37 induces complex responsesin C. albicans, making LL-37 a promising candidate for useas a therapeutic agent against fungal infections.

Microbially induced calcium carbonate precipitation (MICP) has recently become an intelligent and environmentally friendly method for repairing cracks in concrete. To improve on this ability of microbial materials concrete repair, we applied random mutagenesis and optimization of mineralization conditions to improve the quantity and crystal form of microbially precipitated calcium carbonate. Sporosarcina pasteurii ATCC 11859 was used as the starting strain to obtain the mutant with high urease activity by atmospheric and room temperature plasma (ARTP) mutagenesis. Next, we investigated the optimal biomineralization conditions and precipitation crystal form using Plackett-Burman experimental design and response surface methodology (RSM). Biomineralization with 0.73 mol/l calcium chloride, 45 g/l urea, reaction temperature of 45°C, and reaction time of 22 h, significantly increased the amount of precipitated calcium carbonate, which was deposited in the form of calcite crystals. Finally, the repair of concrete using the optimized biomineralization process was evaluated. A comparison of water absorption and adhesion of concrete specimens before and after repairs showed that concrete cracks and surface defects could be efficiently repaired. This study provides a new method to engineer biocementing material for concrete repair.

This paper discusses differences between two popular curriculum approaches in early childhood education: the Project Approach developed in the United States and the Reggio Emilia Approach developed in Italy. Although they are similar in many ways, their differences are mainly due to their divergence in focus on domains of learning: one on science and social science, the other on art. In turn, differences in epistemology, ontology, the purpose of education, the learning process, and types of reasoning are conceptualized. We recommend an integrated approach that blends both approaches through systematic investigation and creativity, objective and subjective aspects of reality, science and social science–oriented and meaning-oriented lessons, planned and spontaneous learning, and deductive and inductive reasoning. We elaborate and term this integration as reflexive pedagogy–to support a child’s learning in a dynamic and dialectical relationship. We then provide examples and suggestions of the successful use of this pedagogy.
