과거 카드3사 개인정보유출 사건을 계기로 전산 프로그램 개발 시에도 운영환경과 동일 수준의 엄격한 전자금융감독규정을 준수하고 있다. 하지만, 전산 프로그램 개발시 해당 응용 프로그램과 연관된 테스트 데이터 변환 대상범위 식별이 불명확하여 테스트 데이터의 무결성이 훼손된 상태로 응용 프로그램을 검증하고 있어, 이 단계에서 발견되지 못한 결함이 서비스 장애로 이어지는 IT운영리스크가 증가되고 있다. 따라서, 본 논문에서는 특정 응용 프로그램과 연관된 테스트 데이터 변환대상 범위 선정을 위한 프로세스와 알고리즘을 제시하여 실증하였다.

Digital fetal monitoring system based on the personal computer combined with the digital signal processing board was implemented. The DSP board acquires and digitally processes ultrasound fetal Doppler signal for digital rectification, FIR filtering, autocorrelation function calculation, its peak detection and MEDIAN filtering. The personal computer interfaced with the DSP board is in charge of graphic display, hardcopy, data transmission and on-line analysis of fetal heart rate change including and variability. I used a recursive technique for autocorrelation function computation method and MEDIAN filter which can greatly reduce the amount of calculation and accuracy. I also implemented analysis algorithm of fetal heart rate change based on normal fetal sample data in order to exact diagnosis.

서비스 산업이 발달할수록 개인의 취향에 좋아하는 정보만을 제공받기 원하고 서비스를 받기 위한 대기시간이 길어지는 것을 좋아하지 않는다. 그러나 기존의 공연장, 극장, 도서관 등의 좌석관리 시스템은 개인의 취향에 맞게 자동으로 좌석 배치를 할 수 없으며 누구나 동일한 정보만 제공하여 준다. 본 논문에서는 이러한 문제점을 개선하기 위하여 개인의 취향에 맞게 즉 신체적인 조건이나 개인의 성향에 맞는 좌석을 지능적으로 배치하고, 선호하는 정보만을 제공할 수 있는 시스템을 제안한다. 제안한 시스템의 성능 확인을 위하여 임의의 극장 좌석 배치도를 이용하여 실험을 한 결과 우수한 성능을 보이는 것을 확인하였다.

인적 서비스의 질은 서비스산업의 경영성과에 영향을 주는 중요한 요인일 뿐만 아니라 조직체의 존속, 성장, 발전에 절대적 영향을 미치므로, 이에 대한 심층적 연구의 필요성이 대두되고 있다. 특히, 신용협동조합의 경우 직원의 대 조합원 서비스의 질은 현재와 같이 어려운 환경 하에서는 조직의 존속과 성장에 더욱 중요한 요소가 되고 있다. 그러므로, 본 연구는 신용협동조합 직원의 인적 서비스의 질에 영향을 미치는 요인들을 중심으로 하여 이들간의 인과관계를 정립하고. 그 요인들이 미치는 영향력을 중심으로 하여 차후의 연구를 위한 시사점을 제공할 목적으로 수행되었다. 이에 따라 본 연구에서는 기존의 연구결과에서 나타난 문제점을 보완하고. 보다 진전된 연구결과를 도출함으로써 신용협동조합 직원들의 대 조합원 서비스의 질에 대한 향상방안을 제시하였다.

The crowdsourcing system relies heavily on the number of crowd participation on the platform to ensure the platform's success. However, exploring factors that motivate the crowds to sustain on the platform remains unclear, and very little literature was found on this matter. Lately, the COVID-19 pandemic has affected the world, including Malaysia. Due to the pandemic, many people have lost their jobs, and hence, most of them have shifted to digital work. Hence, to understand the motivation for continuous participation on the online crowdsourcing platform among low-income crowd workers (B40) in Malaysia, this paper explores the intrinsic and extrinsic motivations for continuous participation. A qualitative method interview was performed where 14 active participants of Upwork.com, under the GLOW program, took part during the data collection process. This paper used the thematic analysis method to extract the data collected from this study. The finding of this study identified eight intrinsic motivation factors: (1) personal development, (2) pastime, (3) fun, (4) passion, (5) task identity, (6) time-workplace flexibility, (7) altruistic, and (8) peers' success and four extrinsic factors: (1) monetary, (2) job security, (3) personal commitment, and (4) environment.

China media environment has drastically changed leading to the an inevitable change of public opinion ecology. Empirical studies have focused less on public opinion guidance, which forms an important component of the government officials' media literacy. This study applied quantitative method in the investigation of media literacy in China. Ideally, media literacy is measured from media cognition, media contact, media usage under the view of public opinion guidance. The findings reveal that the existing problem on 1) incorrect media cognition and public opinion guidance; 2) insufficient contact of personal social media 3) improper tendencies in the use of media to guide the public opinion, especially, on confidential information. Consequently, in order to improve media literacy in China government officials, enhancement of their basic knowledge on news diffusion and public opinion is necessary. Secondly, to effectively deal with "agenda settings", it is important for the government to consider the provision of valuable information and platforms to effectively spread information. So they need to learn how to personally and officially use social media platforms such as Weiboa and Wechat. This ensures they have maximized their potential to acquire valuable information and spread them on valuable platforms. Thirdly, government officials should be able to analyze and understand public opinion trends for official and personal use. Finally, they should understand the development of public opinion and the how online public opinion laws are formed and the target group.

Purpose: The following study seeks to ascertain the motivations behind students' academic major selection and to identify the obstacles they encounter in the transition to university life, with the objective of providing information necessary to adapt well to the university and the course. Thereby, we aim to supply basic resources needed in the development of a university adaptation program to prevent academic dropout. Methods: Between October 1, 2019 and November 29, 2019, a self-administered questionnaire was distributed to a study sample consisting of students currently attending dental technology courses in Gangwondo and Gyeonggido. A total of 474 (94.8%) responses to the questionnaire were received and used for the final analysis. Results: Factors including major selection motivation, intrinsic motivation (p<0.001), academic adjustment (p<0.001), social adjustment (p<0.01), and institutional adjustment (p<0.05) all had negative relationships with academic dropout intention. Personal-emotional adjustment (p<0.001), however, showed a positive relationship with dropout intention. The explanatory power of the model was found to be 50.0%. Conclusion: This research shows that intrinsic motivation and personal-emotional adjustment diminish academic dropout intention. Therefore, it is recommended that diverse postenrolment course-adjustment programs should be developed to improve students' confidence in their choice of study, their adjustment to the course, and their level of satisfaction.

The present and future cities are expanding, and the noise and environmental pollution in cities are getting worse day by day, causing saturation of road and subway traffic. As a result, citizens are spending a great deal of time and money. The use of the sky as a measure to solve this problem has become a reality. However, airplanes that require airstrips and noisy helicopters are difficult to use in cities. As a solution, PAVs and UAMs that generate low noise and enable vertical takeoff and landing using electric energy, motor, hybrid, and hydrogen energy, are attracting attention, with its practicality being promoted in many countries. The development of urban environment and technology has led to the emergence of Personal Air Vehicle (PAV), Vertical Takeoff and Landing (eVTOL), and Urban Air Mobility (UAM) for shipping. Though currently at the level of testing, general commercialization of these air transport means is expected in the next five to fifteen years. This study suggests a plan on the application of human factors to the introduction of PAV and UAM.
