We propose a low power level-up/down shifter with single supply that can be used at SoC with multiple supply. The proposed circuit interfaces IPs which are operated on the different supply voltages. The circuit is designed with a single supply that decreases the low power consumption and the complexity of supply routing and layout. The proposed circuit operated at 500MHz for level-up and at 1GHz for level-down. The level-up/down shifter improves noise immunity of the system at I/O circuit. The circuit is evaluated for 1.8V, 2.5V, 3.3V supply with 0.18um CMOS technology, respectively.

The main objective of this research is how they recognize the face appearance before and after the make-up, based upon the survey on the female college students of their 20s (221 College students in Daegu metropolitan City), who are very conscious about their appearance. In addition, it is to provide the fundamental findings, which are necessary to establish the appearance management of self-concept through the make-up. The results are as follows: About 78% of subjects are performing the make-up on daily basis or needs basis, and 91.6% of the subjects wanted to have more elegant and improved make-up. Comparing the self-satisfaction level before and after the make-up, the satisfaction level on their appearance has been very much improved to 77.2% after the make-up, while the level was 28.8% before the make-up. It has been found out that the purpose of the make-up is more appreciated in pursuing the self-concept, rather than pursuing the beauty. Also we revealed that they could achieve a certain level of psychological stability by improving each individual's social image. We also found out that the stylish and modern style of image contributed more to the satisfaction level of make-up, compared with the image of neatness, individuality, delicacy, or youthfulness.

This study examined which influence the pre-entrepreneurs' individual norm and start-up preparation level have upon a start-up intention, and analyzed a moderating effect in start-up education as for a relationship of individual norm and start-up preparation level with a start-up intention. For the purpose of offering useful data so that the pre-entrepreneurs of planning start-up can do more successful start-up through this, it carried out questionnaire from September 13, 2017 to November 14, 2017 targeting pre-entrepreneurs who received start-up education at an educational institution and a university that are located in K region. As a result, excluding 11 copies with a difficulty in the application to statistics among totally 211 copies, 200 copies were chosen as the final samples. Data were conducted reliability analysis, factor analysis, correlation analysis and regression analysis by using SPSS 20.0. The results are as follows. First, the individual norm had a significant impact on a start-up intention. Second, the start-up preparation level had a significant effect on a start-up intention. Third, the start-up education had a moderating impact in the relationship between the individual norm and the start-up intention. Fourth, the start-up education had a moderating influence in the relationship between the start-up preparation level and the start-up intention. However, this study limited the sampling region to K area, thereby having a limitation in generalizing the findings all over the country. Moreover, there is a suggestion that a continuous research will need to be performed in terms of an influential factor in pre-entrepreneurs' start-up intention as well as in individual norm and start-up preparation level.

We proposed a new High-speed CMOS Level Up/Down Shifter circuits that can be used with Dynamic Voltage and Frequency Scaling(DVFS) algorithm, for low power system in the SoC(System-on-Chip). This circuit used to interface between the other voltage levels in each CMOS circuit boundary, or between multiple core voltage levels in a system bus. Proposed circuit have advantage that decrease speed attenuation and duty ratio distortion problems for interface. The level up/down shifter of the proposed circuit designed that operated from multi core voltages$(0.6\sim1.6V)$ to used voltage level for each IP at the 500MHz input frequency The proposed circuit supports level up shifting from the input voltage levels, that are standard I/O voltages 1.8V, 2.5V, 3.3V, to multiple core voltage levels in between of $0.6V\sim1.6V$, that are used internally in the system. And level down shifter reverse operated at 1Ghz input frequency for same condition. Simulations results are shown to verify the proposed function by Hspice simulation, with $0.6V\sim1.6V$ CMOS Process, $0.13{\mu}m$ IBM CMOS Process and $0.65{\mu}m$ CMOS model parameters. Moreover, it is researched delay time, power dissipation and duty ration distortion of the output voltage witch is proportional to the operating frequency for the proposed circuit.

From a social psychological perspective, Make-up is an tool for run a lot smoother and perform communication efficiently. Many people give a turn to hair color through dyeing form due to yearning to change individual image through the image which the color is having. This paper study how make-up behavior, hair color and self-consciousness will affect the Level of Expected social-psychological effect of College Girl Students. In the sense of make-up behavior, according to result, a group of make-up behavior of self-satisfaction-oriented the level of expected social-psychological effect higher than a group of make-up behavior of tradition-oriented. Hair colors doesn't seem to be having much effect on the level of expected social- psychological effect, but have been shown to influence make-up behavior and self-consciousness. On the self-consciousness, a group of high self-consciousness the level of expected social-psychological effect higher than a group of low or fair self-consciousness. They doesn't have much effect passive expected effect as 'complement of self insufficiency' or 'a person consciousness' But they are affect active expected effect as 'the pleasure of change' and 'positive ascent'.

The purpose of this study is to analyze the effects of start-up risks on university students's entrepreneurial intention. In particular, the start-up risk considers the recent ongoing Covid_19 Pandemic along with the level of awareness of the start-up risk of business administration university students. For this purpose, a total of 204 questionnaires collected for two months from October to November in 2020 were used to verify this relevance empirically through multiple regression analysis. The empirical analysis results are as follows. First, the level of students' awareness of start-up risks has no statistically significant relevance to their entrepreneurial intention, but the higher the level of negative perception of Covid_19 Pandemic, the lower the entrepreneurial intention. On the other hand, additional analysis showed that the students with low self-efficacy majoring in business administration, it was found that negative perceptions of start-up risk had a negative effect on start-up willingness. This study is timely and different from previous studies in that it empirically verified the effect of start-up risk on business administration university students' entrepreneurial intention at a time when negative perceptions of start-up risk increase and COVID_19 Pandemic make it increasingly difficult to start a business administration universit student.

This paper proposed a multi-resolution algorithm. Its search point and complexity were compared with those of block match algorithm. Also the speed up comparison was made with the block match algorithm. The proposed multi-resolution NTSS-3 Level algorithm was compared again with its targets, TSS-3 Level algorithm and NTSS algorithm. The comparison results showed that the NTSS-3 Level algorithm was superior in search point and speed up. Accordingly, the proposed NTSS-3 Level algorithm was two to three times better in search point and two to four times better in complexity calculation than those of the compared object, the block match algorithm. In speed up, the proposed NTSS-3 Level algorithm was two times better. Accordingly, the proposed multi-resolution NTSS-3 Level algorithm showed PSNR ration portion excellency in search point and speed up.

Purpose: The purpose of this study was to compare muscle activation patterns of lower extremities in stroke patients during stepper climbing, stair-up, and level-ground gait conditions by surface electromyography (EMG). Methods: Subjects included 19 hemiplegic patients comprehensive rehabilitation center for inpatients with stroke. Surface EMG was used to measure the subjects' medial gastrocnemius (GCM), tibialis anterior (TA), biceps femoris (BF), and rectus femoris (RF) activity as they took six steps during stepper climbing, stair-up, and level-ground gait conditions. Results: There was no significant difference in the BF or RF muscle activity for the stepper climbing, stair-up, and level-ground gait conditions. However, there were significant differences in the medial GCM and TA muscle activity between each condition on the patients' hemiplegic side(p<0.05). There was significant difference in the medial GCM, TA, RF, and BF muscle activity between each condition on the patients' non-hemiplegic side (p<0.05). Conclusion: As a result, the overall muscle activity during the level-ground gait was higher than the stair-up condition, and the muscle activity during the stair-up condition was higher than the muscle activity during the stepper climbing condition. As one of the many methods used for gait training, we suggest that the stepper exercise could be applied at an earlier stage in the gait training process.

The notions of intuitionistic fuzzy UP-subalgebras and intuitionistic fuzzy UP-ideals of UP-algebras were introduced by Kesorn et al. [13]. In this paper, we introduce the notions of intuitionistic fuzzy near UP-filters, intuitionistic fuzzy UP-filters, and intuitionistic fuzzy strong UP-ideals of UP-algebras, prove their generalizations, and investigate their basic properties. Furthermore, we discuss the relations between intuitionistic fuzzy near UP-filters (resp., intuitionistic fuzzy UP-filters, intuitionistic fuzzy strong UP-ideals) and their upper t-(strong) level subsets and lower t-(strong) level subsets in UP-algebras.
