Since recently only an auto-correlated superposition coding (SC) scheme for non-orthogonal multiple access(NOMA) has been investigated, this paper proposes a cross-correlated SC scheme for NOMA. First, we derive the closed-form expression of the sum rate of the proposed cross-correlated SC scheme. Then, numerical analyses demonstrate that the sum rate of the proposed cross-correlated SC scheme is larger than that of the conventional auto-correlated SC scheme. We also show that for the stronger channel gain user, the signal-to-noise ratio (SNR) gain of the proposed cross-correlated SC scheme is about 15, compared with the conventional auto-correlated SC scheme. As a result, the proposed cross-correlated SC scheme could be a promising technology for 6G ultra-reliable low-latency communications (URLLC).
针对目前研究非正交多址(NOMA)的自相关叠加编码(SC)方案,本文提出了一种互相关的自相关叠加编码(SC)方案。首先,我们推导了所提出的交叉相关SC格式和速率的封闭表达式。数值分析表明,所提出的互相关SC方案的和速率大于传统自相关SC方案的和速率。我们还表明,对于信道增益较强的用户,与传统的自相关SC方案相比,所提出的互相关SC方案的信噪比增益约为15。因此,所提出的交叉相关SC方案可能是一种有前途的6G超可靠低延迟通信(URLLC)技术。

This study was a secondary data analysis conducted to identify the factors affecting the health-related quality of life according to the stress perception level of middle-aged. Data from the 2014, 2016, and 2018 Korean National Health and Nutrition Examination Survey were used, and 7,995 people aged 40-64 who answered the level of stress perception were targeted. Data analysis was performed using IBM SPSS ver.25.0, and the significance level was set to .05. As a result of the study, in the feeling less stressed group, household income level, education level, frequency of dinning out, drinking amount at a time, smoking, subjective health, and depression were found to be significant influencing factors, and the explanatory power was 21.4% (p < .001). In the feeling a lot stressed group, household income level, education level, living with a spouse, weekly breakfast frequency, aerobic physical activity, smoking, subjective health, and depression were significant influencing factors, and the explanatory power was 38.7% (p < .001). Therefore, it is suggested to consider each influencing factor in the middle-aged stress reduction intervention.
本研究是根据中年人的压力感知水平,对影响健康相关生活质量的因素进行二次数据分析。以2014年、2016年、2018年国民健康营养调查的数据为对象,调查了7995名回答“压力感知水平”的40 ~ 64岁的人。采用IBM SPSS ver.25.0进行数据分析,显著性水平设为0.05。研究结果发现,在压力较小的群体中,家庭收入水平、受教育程度、外出就餐频率、一次饮酒量、吸烟情况、主观健康状况、抑郁情绪是显著影响因素,解释能力为21.4% (p < 0.001)。在压力大组中,家庭收入水平、受教育程度、与配偶同住、每周早餐频次、有氧运动、吸烟、主观健康、抑郁是显著影响因素,解释能力为38.7% (p < 0.001)。因此,建议在中年减压干预中综合考虑各影响因素。

This study aimed to identify the relationship between academic and clinical practice stress and major satisfaction of nursing students. The data was collected from 140 nursing students by the online survey. Data were analyzed using SPSS 18.0. As a result of analyzing the differences in academic stress, clinical practice stress, and major satisfaction according to general characteristics, it was found that academic stress had a difference with religion (F = 14.348, p < .001). And there was a statistical difference in major satisfaction with grade (F = 4.582, p = .004). As for the correlation between academic and clinical practice stress, and major satisfaction, academic stress and clinical practice stress were positively correlated (r = .388, p <.01), and clinical practice stress had a positive correlation with major satisfaction (r=.336, p<.01). Therefore, it is considered that it is necessary to develop a program to lower academic stress in order to improve the satisfaction of the majors of nursing students.

A novel selective oxidation process has been developed for low source/drain (S/D) series resistance of the fin channel metal oxide semiconductor field effect transistor (MOSFET). Using this technique, the selective oxidation fin-channel MOSFET (SoxFET) has the gate-all-around structure and gradually enhanced S/D extension regions. The SoxFET demonstrated over 70% reduction in S/D series resistance compared to the control device. Moreover, it was found that the SoxFET behaved better in performance, not only a higher drive current but also higher transconductances with suppressing subthreshold swing and drain induced barrier lowering (DIBL) characteristics, than the control device. The saturation current, threshold voltage, peak linear transconductance, peak saturation transconductance, subthreshold swing, and DIBL for the fabricated SoxFET are 305 μA/μm, 0.33 V, 13.5 μS, 76.4 μS, 78 mV/dec, and 62 mV/V, respectively.
针对翅片沟道金属氧化物半导体场效应晶体管(MOSFET)的低源/漏极(S/D)串联电阻,提出了一种新的选择性氧化工艺。采用该技术制备的选择性氧化鳍状沟道MOSFET (SoxFET)具有栅极全方位结构和逐渐增强的S/D扩展区。与控制器件相比,SoxFET的S/D串联电阻降低了70%以上。结果表明,与控制器件相比,SoxFET不仅具有更高的驱动电流,而且具有更高的跨导率,具有抑制亚阈值摆幅和降低漏极诱导势垒(DIBL)的特性。SoxFET的饱和电流、阈值电压、峰值线性跨导、峰值饱和跨导、亚阈值摆幅和DIBL分别为305 μA/μm、0.33 V、13.5 μS、76.4 μS、78 mV/dec和62 mV/V。

The paper dealt with the fact that the green deal took place when the demand for electrical energy surged. However, the procurement of electric vehicles and much of the electric energy of the future still depends on fossil fuels. Accordingly, the importance of the IT industry is highlighted, and the demand for hydrogen-electric vehicles and related industries increases. The method of this study investigated the relevance of EV charging as a future next-generation power source rather than the electric energy demand of the IT industry. This study derives the correlation between industrial electricity and household energy PPP according to economic growth through empirical regression analysis. As the result, it was found that the amount of change, including electric and next-generation electric vehicles, was significant for on thirds of the countries in the change in purchasing power compared to GDP. This affects overall purchasing power as twelve out of thirty two countries with EV demand (Italy, Canada, Switzerland, Poland, Slovenia, Germany, Slovakia, Finland, Sweden, Czech Republic, Estonia, Denmark) are more sensitive to electric energy. This is related to the charging of EVs or hydrogen as the next-generation power of the future rather than the electric energy demand of the IT industry. By preventing waste of unused electricity of IT-electric energy sources and charging-preserving hydrogen electricity, it seems indispensable to prepare for the national IT power conservation buffer facility for supply and demand in future growth.
这篇论文讨论了这样一个事实,即绿色交易发生在电力需求激增的时候。然而,电动汽车和未来大部分电能的采购仍然依赖于化石燃料。因此,信息技术(IT)产业的重要性得到突出,对氢动力汽车等相关产业的需求也在增加。本研究的方法是调查电动汽车充电作为未来下一代电源的相关性,而不是IT行业的电力能源需求。本研究通过实证回归分析,推导出工业用电与居民能源购买力平价随经济增长的相关性。结果发现,在三分之一的国家中,包括电动汽车和下一代电动汽车在内的购买力变化与GDP相比是显著的。这影响了整体购买力,因为32个有电动汽车需求的国家中有12个(意大利、加拿大、瑞士、波兰、斯洛文尼亚、德国、斯洛伐克、芬兰、瑞典、捷克共和国、爱沙尼亚、丹麦)对电能更敏感。这与其说是信息技术(IT)产业的电力需求问题,不如说是与电动汽车(ev)或氢气充电有关。防止信息技术(it)能源的未使用电力的浪费和保留充电的氢电力,为未来增长的供给和需求准备国家信息技术(it)电力节约缓冲设施是必不可少的。

Objectives: Antibiotics help treat Vaginitis, and prolonged usage of antibiotics can lead to resistance. Methods: This study investigates the antimicrobial activity of two types of lactic acid bacteria using essential oils. After cultivation by adding grapefruit seed extract (GSE), eucalyptus, tea tree, clove bud, cinnamon, lemongrass, thyme, and ginger oils in a specific ratio, pathogenic microorganisms, namely E. coli, C. albicans, and lactic acid bacteria were released. The number of bacteria was measured using a medium suitable for the strains. Results: The essential oils and GSE inhibited pathogenic microorganisms, and the inhibitory concentration of GSE against pathogenic bacteria (E. coli, C. albicans) was confirmed. The non-inhibitory mixing ratio was also confirmed (50 μl of eucalyptus globulus (EG) oil and 50 μl of melaleuca alternifolia oil (tea tree oil, TTO) at 200 ppm GSE (pH 5.0, 5.5, 6.0)). Conclusion: Essential oils can be considered as an alternative to antibiotics because of their antibacterial properties. They are useful as auxiliary antibacterial agents for patients under long-term antibiotic treatment.

The Role of Information Search Cost on Seller's Disclosure of Negative Information 信息搜索成本对卖方负面信息披露的影响
Pub Date : 2021-04-01 DOI: 10.22156/CS4SMB.2021.11.04.230
Seung-Hyeon Huh
This study has attempted to provide an important understanding about the information asymmetry in markets through empirical analysis on how the disclosure of low quality can increase demand even in the short run. More specifically, this study has extended the previous findings from the related literature by considering the effect of information search cost and providing empirical evidences about the effect of voluntary disclosure of low quality, using an experimental method with purchase scenarios. The results from our analysis show that reduced perceived risk have an important effect on sharing negative information, while the effect of information search cost is minimal. We also explain the circumstances whereby the information disclosure of a seller with low-quality product can enhance not only the seller’s profitability but also customers’ welfare by increasing the market demand and the demand for the seller claiming high quality.
本研究试图通过对低质量的信息披露如何在短期内增加需求的实证分析,为市场信息不对称提供一个重要的认识。更具体地说,本研究采用带有购买场景的实验方法,考虑了信息搜索成本的影响,拓展了相关文献的研究成果,提供了低质量自愿披露效应的实证证据。分析结果表明,感知风险的降低对负面信息共享有重要影响,而信息搜索成本的影响很小。我们还解释了在何种情况下,低质量产品的卖方信息披露不仅可以提高卖方的盈利能力,还可以通过增加市场需求和对卖方声称高质量的需求来提高消费者的福利。

The present study intends to understand how multimodality can be implemented in a content course curriculum and how students perceive multimodal tasks. Twenty-eight students majoring in English were engaged in a digital storytelling assignment as a part of the content curriculum. Findings from the questionnaire and reflective essays that investigated students perceptions of digital storytelling showed that students felt that the assignment helped them engage in the task and felt motivated. In comparison to traditional writing tasks, students perceived digital storytelling to be more engaging and motivating, but felt that the assignment required more mental effort and caused more anxiety. By supporting students to explore technology and implement multimodal aspects in the learning process, digital storytelling can encourage engagement and autonomous learning to create meaningful works that are purposeful and enjoyable.
本研究旨在了解多模态如何在内容课程中实施,以及学生如何感知多模态任务。作为内容课程的一部分,28名英语专业的学生参与了一项数字故事作业。问卷调查和反思性文章调查了学生对数字讲故事的看法,结果表明,学生们认为这项作业有助于他们参与到任务中,并感到有动力。与传统的写作任务相比,学生们认为数字讲故事更吸引人,更有动力,但他们觉得这项任务需要更多的脑力劳动,也会带来更多的焦虑。通过支持学生在学习过程中探索技术和实施多模式方面,数字化讲故事可以鼓励学生参与和自主学习,从而创造出有意义的、有目的的、令人愉快的作品。

By supporting students to explore technology and implement multimodal aspects in the learning process, digital storytelling can encourage engagement and autonomous learning to create meaningful works that are purposeful and enjoyable.","PeriodicalId":15438,"journal":{"name":"Journal of Convergence Information Technology","volume":"26 1","pages":"174-184"},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89110812","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Our society is developing exponentially, but schools are not keeping up with the pace of society's development, and they are not providing digital literacy education suitable for the growth and development of students. Thus, this study identified the actual conditions and problems of digital literacy education at school sites and sought the direction of development of digital literacy education. By identifying the current state of schools in which the 2015 curriculum is operated, we sought the direction of the development of digital literacy education for our school. First, old digital devices should be replaced, laptops or smart devices should be provided for each student, and internet access should be available throughout the school. Second, digital literacy education should be provided to teachers by providing various training opportunities.Third, coding education where you can express what you think as logical thinking, Software training should increase the level of the algorithmic domain that shows the computational thinking process of discovering problems and automating a given problem into a computer programming language, there is enough robot that can be seen operating the program, digital parish will need to be delivered.
我们的社会正呈指数级发展,但学校却没有跟上社会发展的步伐,没有提供适合学生成长和发展的数字素养教育。因此,本研究明确了学校现场数字素养教育的实际情况和存在的问题,寻求数字素养教育的发展方向。通过确定2015年课程运行学校的现状,我们为学校寻求数字素养教育的发展方向。首先,应该更换旧的数字设备,为每个学生提供笔记本电脑或智能设备,并在整个学校提供互联网接入。第二,通过提供各种培训机会,对教师进行数字素养教育。第三,编码教育,你可以用逻辑思维来表达你的想法。软件培训应该提高算法领域的水平,展示发现问题的计算思维过程,并将给定的问题自动化成计算机编程语言,有足够的机器人可以看到操作程序,数字教区将需要交付。
