Developments in artificial intelligence such as natural language processing (NLP) and automatic speech recognition (ASR) are making it a viable option to incorporate AI-powered language learning applications into the classroom. Researchers and practitioners have started to experiment with a variety of speech technology for pedagogical use. However, little research has explored the benefits and limitations of applying the AI-based language applications to primary school English education settings

The swim-up method is superior for enriching genetically competent sperm.

본 연구는 포도 재배 중 살충제 bifenthrin을 살포하고, 살포 후 0, 1, 2, 3, 5, 7, 10, 15일에 포도 시료를 채취하여 bifenthrin을 분석하고 bifenthrin의 생물학적 반감기를 산출한 다음 생산단계 농약 잔류허용기준(PHRL; Pre-Harvest Residue Limit)을 설정하였다. 포도 중 bifenthrin은 acetonitrile과 dichloromethane 으로 추출 및 분배 하여 GC/ECD로 분석 하였다. Bifenthrin의 정량한계는 0.01 ng이었고, 평균 회수율은 0.1 및 0.5 mg kg-1 두 수준에서 각각 104.08±1.24%와 92.25±3.13%이었다. 포도 중 bifenthrin의 기준량 및 배량 살포시 생물학적 반감기는 각각 21일과 23일로 계산되었다. 또한 증체량에 따른 희석효과가 bifenthrin의 잔류량 감소에 있어 주요인자로 작용하지는 않았다. 잔류감소 회귀식을 이용한 생산단계 농약 잔류허용기준

DOR may be associated with a higher risk of EP in IVF/ET cycles with controlled ovarian stimulation. More careful monitoring may be necessary for pregnant women with DOR.

Our study demonstrated that BRCA carriers with breast cancer had comparable ovarian reserve to non-carriers but the response to ovarian stimulation was lower. We also observed that oocyte maturity was higher in TNBC patients, however age might be a confounding factor of this result.

Research on evacuation plans for reducing damages and casualties has been conducted to advise defenders against threats. However, despite the attention given to the research in the past, emergency response management, designed to neutralize hazards, has been undermined since planners frequently fail to apprehend the complexities and contexts of the emergency situation. Therefore, this study considers a response problem with unique characteristics for the duration of the emergency. An early stage

With recent developments in artificial intelligence, students are starting to actively embrace machine translation for a variety of purposes. However, English teachers feel ambivalent about introducing this new technology into classroom settings, raising concern about its educational value and effectiveness. The situation requires an empirical investigation into the affordances and constraints of machine translation within specific educational contexts. Given these intersecting developments, the

We found that the type "d" spermatozoa displayed no DNA fragmentation, but the other types of spermatozoa also displayed very low rates of DNA fragmentation. This result may be associated with the processing of the spermatozoa by density gradient centrifugation and the swim-up technique.

Estrogen-dependent early stage endometrial cancer is relatively common in young women of reproductive age. The standard treatment is hysterectomy and bilateral salpingo-oophorectomy (BSO), even in early stage well-differentiated endometrial cancer patients. This surgical option results in permanent loss of fertility. There have been some reports of live births using in vitro fertilization after conservative management of endometrial cancer with high-dose progestin for the purpose of fertility pr

The objective of this study was to evaluate predicting factors for supraphysiologic serum estradiol elevation during controlled ovarian stimulation (COS) with administration of letrozole and gonadotropins in patients with estrogen-dependent cancer. Use of aromatase inhibitors is recommended to prevent the potential effects of elevated serum estradiol levels and recurrence of tumor in patients with estrogen-dependent cancers during COS. Although previous studies reported that letrozole have shown
