In most countries, public libraries have played a role as a hub of knowledge and information, complex culture of local communities, and a third place for meeting and communication. And recent public libraries are focusing on enhancing their core competencies and expanding services using digital technologies to meet the era of digital transformation and the 4th industrial revolution. However, after the COVID-19 pandemic occurred, all public libraries are repeatedly closed, reopened, and partially closed, and all resources are devoted to providing non-contact, digital and online alternative services, and are expected to continue in the future. As a result, future public libraries are bound to face a trilemma in which digital expandability, complex cultural space, and importance as a place of knowledge and information service are conflicting. This study discoursed on the public library trilemma in the post-COVID-19 era and suggested ways to overcome it. The orientation of the future public library is the fusion and harmony of multiplicity and multipurpose, place and space, knowledge & information and complex culture, face-to-face service and remote service. The main body of a public library is not the finger (digital and non-contact), but the moon (knowledge information center).

We propose a damascene gate FinFET with Si nanocrystals implemented on bulk silicon wafer for low voltage flash memory device. The use of optimized SRON (Silicon-Rich Oxynitride) process allows a high degree of control of the Si excess in the oxide. The FinFET with Si nanocrystals shows high program/erase (P/E) speed, large $V_{TH}$ shifts over 2.5V at 12V/$10{\mu}s$ for program and -12V/1ms for erase, good retention time, and acceptable endurance characteristics. Si nanocrystal memory with damascene gate FinFET is a solution of gate stack and voltage scaling for future generations of flash memory device. Index Terms-FinFET, Si-nanocrystal, SRON(Si-Rich Oxynitride), flash memory device.

The purpose of this study is to analyze the curriculum of the University-affiliated Science Gifted Education Center from 2018 to 2020 to analyze the proportion of the information area in the total class and the contents of the class, thereby confirming the trend change in the information area. After analyzing the number of hours that information education occupies in the total number of class hours, information education was classified into three categories: computer use education, SW coding education, and SW convergence education, and the curriculum was analyzed in detail. The analysis results are summarized as follows. First, the proportion of information education in total education is gradually increasing compared to 2018. Second, the proportion of computer utilization education in information education is relatively decreasing, and SW coding education and SW convergence education are expanding. Considering that the field of information education has been expanded in various forms, more systematic information education will be provided to students in the future and its usefulness will increase rapidly.

With the development of high-speed railway technologies, train velocities can now reach speeds up to 350 km/h, and higher in the future. In high-speed railway systems (HSRs), loss of communication can result in serious accidents, especially when the train is controlled through wireless communications. For to this reason, operators of Long Term Evolution for Railway (LTE-R) communication systems install eNodeBs (eNBs) with high density to achieve highly reliable communications. However, densely located eNBs can result in unnecessary frequent handovers (HOs) resulting in instability because, during every HO process, there is a period of time in which the communication link is disconnected. To solve this problem, in this paper, an HO scheme based on the maximum cell residence time (CRT) and adaptive time to trigger (aTTT), which are collectively called CaT, is proposed to reduce unnecessary HOs (using CRT estimations) and decrease HO failures by improving the handover command transmission point (HCTP) in LTE-R HSR communications.

The existed transmissions have PDH and SDH transmission system, which are based on PSTN network. But as the future ATM network is going to be constructed, it is very necessary for ATM network to interwork with PSTN for telephony service. The international standardization organizations like ITU-T, ATM Forum offered CES, VTOA1, VTOA2 and so on for interworking with PSTN service, which spend many network resources and considerable transmission delay. So in this paper, new interworking PSTN for transmission will be proposed to lessen the transmission delay and the network resources.

The purpose of this study is to suggest the implications of social welfare workers' understanding of emotional labor and prevention of psychological exhaustion. In order to achieve this goal, I analyzed the effects of the levels of surface acting and deep acting, which are components of emotional labor in social welfare workers in social welfare center, on emotional exhaustion, depersonalization, and lack of sense of personal accomplishment which are components of psychological exhaustion. And I empirically analyzed how emotional labor affects psychological exhaustion, when superior support and fellow support as components of social support play a role as moderating variables. Empirical results show that emotional labor affects psychological exhaustion and social support plays a moderating role. Based on these results, theoretical and policy implications and future research directions are presented.
