This paper describes a low-power CMOS analog front-end block for UHF band RFID tag chips. It satisfies ISO/IEC 18000-6C and includes a memory block for test. For reducing power consumption, it operates with an internally generated power supply of 1V. An ASK demodulator using a current-mode schmitt trigger is proposed and designed. The proposed demodulator can more exactly demodulate than conventional demodulator with low current consumption. It is designed using a $0.18{\mu}m$ CMOS technology. Measurement results show that it can operate properly with an input as low as $0.25V_{peak}$ and consumes $2.63{\mu}A$. The chip size is $0.12mm^2$.

Within the framework of the ASTRID project, core design studies are being conducted by the CEA with support from AREVA and EDF. The pre-conceptual design studies are being conducted in accordance with the GEN IV reactor objectives, particularly in terms of improving safety. This involves limiting the consequences of 1) a hypothetical control rod withdrawal accident (by minimizing the core reactivity loss during the irradiation cycle), and 2) an hypothetical loss-of-flow accident (by reducing the sodium void worth). Two types of cores are being studied for the ASTRID project. The first is based on a 'large pin/small spacing wire' concept derived from the SFR V2b, while the other is based on an innovative CFV design. A distinctive feature of the CFV core is its negative sodium void worth. In 2011, the evaluation of a preliminary version (v1) of this CFV core for ASTRID underlined its potential capacity to improve the prevention of severe accidents. An improved version of the ASTRID CFV core (v2) was proposed in 2012 to comply with all the control rod withdrawal criteria, while increasing safety margins for all unprotected-loss-of-flow (ULOF) transients and improving the general design. This paper describes the CFV v2 design options and reports on the progress of the studies at the end of pre-conceptual design phase 1 concerning: - Core performance, - Intrinsic behavior during unprotected transients, - Simulation of severe accident scenarios, - Qualification requirements. The paper also specifies the open options for the materials, sub-assemblies, absorbers, and core monitoring that will continue to be studied during the conceptual design phase.

This study investigates human-robot interactions in a museum environment. Unlike robots in movies, robots in real life do not have 'personality,' but instead have a specific purpose and function. This research is primarily about the assignment of specific and appropriate personalities to robots in different contexts. Methods by which a definite personality can be imparted on a robot are discussed in this research. Previous research has addressed attempts to assign a robot personality based on the task context. However, the discussion of robot personality is incomplete. Therefore, we assumed that a robot's character was dependent on the characteristics of its location of use. We planned a $2{\times}2$ comparison of various robot personalities, i.e., introverted or extroverted paired with either a traditional museum or a process-oriented experiential experience. Based on Schmitt's (1999) strategic experiential modules, experiential factors were derived for each set of conditions. To achieve the objectives of the research, theoretical and empirical research were conducted simultaneously. The software JMP 9 was used to verify the research model and hypotheses.

This convergence study examines the case of the Andaz Hotel branches, which sees the critical elements of a characteristic boutique hotel as an experience and makes a successful case with rich experience content in the hotel. By examining sixteen experience content categories, eight from the Andaz India Delhi branch and Tokyo branch in Japan and analyzing them through Schmitt's five experience modules, we have found that both branches had strong experience content in most of the modules, in line with the brand philosophy of creating hotels that make the most of the local characteristics. The study also showed that the Toranomon Hills branch had stronger emotional experience contents than the Delhi branch, and the Delhi branch had a little stronger in the case of cognitive experience contents. Both branches were found to have rich experience content at various points encountered by the guests while using the hotel.

Objectives: The purpose of the study was to investigate the influence of instructor trust on learning flow and academic achievement in dental hygiene students. Methods: A self-reported questionnaire was completed by 202 dental hygiene students in Gyeongnam from July to August, 2016. A five point Likert scale questionnaire consisted of intimacy (8 items), professionalism (8 items), teaching ability (5 items), and leadership (6 items). Measurement of learning flow was adapted and modified by Kim et al. Academic achievement was adapted and modified by Noe and Schmitt. Cronbach's ${\alpha}$ of learning flow was 0.77 and that of academic achievement was 0.78 in the study. Data wee analyzed by t-test, one way ANOVA, $Scheff{\acute{e}}$ test, and Pearson's correlation using SPSS 23.0 program. Results: The scores of instructor trust, learning flow, and academic achievement were 4.37, 3.46, and 3.23, respectively. Academic achievement had a close positive correlation with instructor trust (r=0.46, p<0.001) and learning flow (r=0.63, p<0.001). Instructor trust had a positive correlation with learning flow (r=0.50, p<0.001). Learning flow took mediating effects on instructor trust and academic achievement. Conclusions: The trust between students and instructors had a great influence on learning flow and academic achievement. So the instructor should try to make the students concentrate on learning.

For the purpose of designing novel capacitance pressure sensor, several effects on sensitivity such as parasitic capacitance effects, temperature/thermal drift and leakage current have to be eleiminated. This paper proposed the experimental studies on frequency compensation method by electronic circuit technique, C-V converting method with switched capacitor and C-F converting method with schmitt trigger circuit. The third interface circuit by frequency compensation method is composed to eliminate the drift and leakage component by comparision sensing frequency with reference frequency. The signal transmission is realized by digital signal to minimize the influence of noise and high resolution is obtained by means of increasing the number of digital bits. In the fabricated high performance C-V interface, the offset voltage was not appeared, and in case of voltage source, 4.0V, feed back capacitance, 10㎊, the pressure, 0~10 ㎪, the sensitivity of C-V converter is 28 ㎷/㎪.V, the temperature drift characteristic, 0.051 %F.S./$^{\circ}C$ and C-F converter shows -6.6 Hz/pa, 0.078 %F.S./$^{\circ}C$ respectively, relatively good ones.

A novel capacitance deviation-to-time interval converter based on ramp-integration is presented. It consists of two current mirrors, two schmitt triggers, and control digital circuits by the upper and lower sides, symmetrically. Total circuit has been with discrete components. The results show that the proposed converter has a linearity error of less than 1% at the time interval(pulse width) over a capacitance deviation from 295 pF to 375 pF. A capacitance deviation of 40pF and time interval of 0.2 ms was measured for sensor capacitance of 335 pF. Therefore, the high-resolution can be known by counting the fast and stable clock pulses gated into a counter for time interval. The application of a novel capacitance deviation-to time interval converter to a digital humidity controller is also presented. The presented circuit is insensitive to the capacitance difference in disregard of voltage source or temperature deviation. Besides the accuracy, it features the small MOS device count integrable onto a small chip area. The circuit is thus particularly suitable for the on-chip interface.

Despite the declining birth rate and consequent lower children population in Korea in recent years, there has nevertheless been found to be a positive trend in relation to the purchase of toddler and children's wear. This has led toddler and children's wear to pursue sales and marketing strategies. There is especially a growing number of experiential marketing that provide an empirical element, which stimulate con- sumers' emotions, and also create a relationship with a brand. Therefore, this research aims to serve as practical data for the planning and implementation of experiential marketing strategies through the analysis of experiential marketing cases conducted by brands of toddler and children's wear. The study examines the status of the Korean toddler and children's fashion market between 2009 and 2018. The domestic brands of toddler and children's wear were analyzed with the application of Bernd H. Schmitt's five experiential modules. The analysis results first showed that of the five modules, 'feel' held the highest proportion, followed by 'think' and 'act', and lastly 'sense' and 'relate'. Second, the experiential marketing stimulated more than three of the five senses. Third, experiential marketing that provided educational experiences to children was conducted. Fourth, an experience was provided for parents and children to enjoy together. Finally, product promotion and purchase were naturally linked. The study's results have confirmed that toddler and children's wear brands implement experiential marketing strategies, which convey the emotional and cultural experiences shared by parents and children in various ways.

The purpose of this study is to classify customer experience components using Bernd H. Schmitt's Strategic Experiential Modules and explore the relevance between fashion lifestyle and customer experience components. A survey was conducted on 400 adults between the ages of 20s to 50s who had experience in sportswear stores. The results obtained are as follows. First, according to fashion lifestyle, the respondents were divided into an individuality-valued pragmatic group, a trend-oriented brand-seeking group, a fashion-interested group, and a conservative pragmatic group. Second, customer experience components were divided into sensory experience, emotional experience, cognitive experience, behavioral experience, and relational experience. Third, on analyzing the relationship between customer experience and fashion lifestyle, it was found that a fashion-interested group has the highest value in all experiences; therefore, it can be considered that the higher the interest in fashion, the more important is the customer experience. On the other hand, the conservative pragmatic group represented generally smaller values than the other three groups in all customer experiences. Fourth, there were significant differences in the customer experience components that were considered to be important depending on the fashion lifestyle type. An individuality-valued pragmatic group valued cognitive experiences, a fashion-interested group valued all experiences, and a conservative pragmatic group showed low scores in all customer experiences. The results of this study will allow companies to build more customer-friendly experiences and enable consumers to engage in satisfactory purchasing activities through better customer experiences.
