This study was conducted to understand the motivation for major selection and degree of satisfaction with major for university students in the department of Radiology, and to analyze the effect university life adjustment in COVID-19. From Jung 20 to July 20, 2021, 308 students in grades 1~4 were enrolled at universities in Busan and Gyeongnam. Factors influencing university life adjustment were found to have a good adjustment when majoring was selected with personal motive rather than social motive. Among the sub-factors of major satisfaction, general satisfaction and satisfaction with surrounding relationships had a positive effect on university life adjustment. Therefore, in order to adapt to healthy university life, it is necessary to secure closeness between school, professor, and students, and it is desirable to provide students with opportunities to experience various education by recognizing the rapidly changing policy changes in education to increase major satisfaction. Based on the results of this study, it is expected that the results of this study will be used as basic data for successful university life of students in the department of radiology.

Although personal media have become a giant industry, there is a lack of understanding of personal media creators. Therefore, this study aims to clarify factors influencing personal media creators' choice of platform. According to the analysis, there is a significant difference between the factors considered by YouTube, AfreecaTV, and Twitch creators. Moreover, the moderating effect of creators' main genre and broadcasting type were also found to be partially significant. It was found that both creators who share the motive of vividness and communication as their main genre and creators who focus on recording and broadcasting with career development motivation prefer YouTube.

Purpose: The purposes of this study were to understand the health interest of consumers in the United States and Japan and thus understand the motivation of food choices, in order to provide basic data on the country's strategy based on healthy and correct food choices in the future. Methods: A customer survey was conducted in 2019 from October 18 to 31, and it targeted 115 American and 120 Japanese local consumers between the ages of 20- to 64-years-old. Eight questions were formed using General Health Interest. Based on food choice motivation, 27 questions were reconstructed and asked about demographic information. All data were analyzed by SPSS Statistics (ver. 25). Results: Health consciousness was categorized into 2 types: nutrition-seeking type and preference-seeking type. Based on these 2 factors, customers were grouped into 3 clusters: healthy dietary life-seeking group, nutrition balance-seeking group and health indifference group. Food choice motivation was categorized into 4 types: health, efficiency, value, and mood. All 3 groups showed a high tendency for efficiency in common. The results show that consumers want higher satisfaction with their time and money invested in food consumption. It is believed that the focus and investment of market segmentation strategy should be focused on product development, especially for American and Japanese consumers who are interested in health. Conclusion: The results of this study reflect consumer needs that can assist in the selection of healthy and correct foods in the future.

This study examined the factors that affect the relationship between radish liquid naturally fermented bread selection motive, consumer attitude and purchase intention. A total of 300 questionnaires were distributed to the consumers, of which 279 were deemed suitable for analysis after the removal of 21 unusable responses. In order to perform statistical analyses required in the study, SPSS 18.0 statistical program was employed for frequency analysis, factor analysis, and reliability analysis, correlations, regression analysis. The results of exploratory factor analysis showed that four factors regarding naturally fermented bread selection motive were extracted from all measurements with a KMO of 0.735 and a total cumulative variance of 65.759 %, with regard to consumer attitude, one factor was extracted with a total cumulative variance of 72.421% and a KMO score of 0.684. One factor for purchase intention was extracted that accounted for a total cumulative variance of 67.139% and a KMO score of 0.683. All factors were significant at 0.000 and the correlation between variables was significant. Thus, based on the results, the main research hypothesis that identifies the relationships selection motive between consumer attitudes and purchase intetion was adopted.

This paper presents a method which synthesizes asynchronous circuits from free-choice Signal Transition Graphs (STGs) with timing constraints. The proposed method synthesizes asynchronous circuits by analyzing: the relations between signal transitions directly from the STGs without generating state graphs. The synthesis procedure decomposes a free-choice STG into deterministic STGs which do not have choice behavior. Then, a timing analysis extracts the timed concurrency and tamed causality relations between any two signal transitions for each deterministic STG. The synthesis procedure synthesizes circuits for each deterministic STG and synthesizes the final circuit by merging the circuits for each deterministic STG. The experimental results show that our method achieves significant reductions in synthesis time for the circuits which have a large state space, and generates circuits that have nearly the same area as compared to previous methods.

In frequency selective channels, conventional PN code acquisition schemes are not ideal candidates. This is because they are primarily designed for the AWGN channel. In this paper, a direct-sequence spread-spectrum(DSSS) PN code acquisition system based on digital matched filtering (DMF) with automatic threshold control(ATC) algorithm is presented and analyzed with regards to probability of detection and probability of false alarm. These two important probabilities, the probability of detection ($P_D$) and the probability of false alarm ($P_{FA}$) are derived and analyzed in considering Doppler shift, sampling rate, mean acquisition time, and PN chip rate in frequency selective Rayleigh fading channel when using serial-search method as detection technique. From computer simulation results of a DMF acquisition system model, it is shown that the performance of the acquisition system using ATC algorithm is better than that of constant threshold system.

식품 선택의 동기는 다양하며 개인의 가치관에 많은 영향을 받는다. 유아기는 여러 가지 기본개념들이 형성되는 시기로 이 시기에 잘못된 교육을 받을 경우 개념이 정확하게 형성되지 못하거나 왜곡된 개념이 형성될 수 있다. 이는 평생의 건강을 좌우할 수도 있으므로 유아기의 올바른 식사에 대한 가치관 정립은 매우 중요하다. 그러나 유아의 식품섭취에 미치는 영향이 큰 것으로 보고되고 있는 어머니의 식품선택 동기에 대한 체계적인 조사는 이루어지지 못하고 있다.(중략)

긍/부정 선택 실험에서 나타나는 뇌파 변화를 연구하였다. 서로 다른 위치에서 측정된 뇌파의 시공간적 상호관계를 정량화하는 변수로, 시간영역에서 계산하기 용이한 동기율(synchronization rate), 편향성(synchronization rate), 편향성(polarity), 상호상관(cross-correlation) 등의 변수를 도입하여, 긍/부정 선택 순간의 뇌파 변화를 살펴보았다. 좌우 전전두엽(Fp1, Fp2)에서 특정된 뇌파를 사용하여 계산한 동기율, 편향성의 평균과 요동폭, 상호상관 등은, 선택 순간 근처에서, 평상시에 뇌파와 통계적으로 유의미한 차이를 보였다.

병행적 프로그램 개발을 위한 Java 언어의 기능은 저수준의 기능으로 프로그래밍이 불편하고 오류를 범할 가능성이 높다. 본 논문에서는 병렬 알고리즘에서 빈번히 활용되는 세마포어, 여러 유형의 버퍼와 버퍼그룹, 베리어 작업 영역등의 동기화 제어구조를 클래스 라이브러리의 형태로 개발하였다. 이 라이브러리를 활용하면 동기화 기능의 구현에 관한 복잡한 내용이 제어구조 클래스에 효과적으로 은폐되고, 병렬 알고리즘의 구조와 이를 구현하기 위한 제어가 분리될 수 있다. 단일 목적의 동기화 기능을 위하여 복수 구현이 제공되므로 알고리즘의 구조를 수정하지 않으면서도 보다 적절한 구현을 선택하도록 프로그램을 변경할수도 있다.
