인터넷 개인 방송의 확산에 따라 개인 방송 진행자(BJ, Broadcasting Jockey)와 시청자 수가 증가하고 있으며 이들 간 즉각적인 의사소통도 활발하게 일어나고 있다. 본 연구는 인터넷 개인 방송에서 사회적 문제를 야기하고 있는 일부 BJ들의 자극적인 방송에 주목하고 BJ의 일탈 행위를 억제하는 기제가 효과적으로 작동되는지 그리고 BJ와 상호작용을 하는 시청자들은 어떤 영향을 미치는지 알아본다. 구조방정식 모형을 통해 억제 이론의 공식적 및 비공식적 제재가 BJ의 정책 준수 태도를 통해 일탈 방송 의도에 미치는 영향을 살펴보고 BJ의 정책 준수 태도와 일탈 방송 의도와의 관계에 대한 사회적 압력의 조절효과를 확인하였다. 아프리카 TV의 BJ를 대상으로 설문하여 총 234개의 데이터를 분석한 결과 공식적 제재 뿐만 아니라 비공식적 제재 또한 BJ들의 정책 준수 태도를 높이는 것으로 나타났다. 하지만, BJ가 인터넷 개인 방송을 시청하는 시청자로부터 인식하는 사회적 압력은 정책 준수 태도가 일탈 방송 의도를 줄이는 효과를 감소시키는 것으로 확인되었다.

In this paper we discuss a direct satellite broadcasting system for vehicle. The proposed satellite-steering algorithm and controller based on it are designed for a communication and broadcasting system which uses the Mugungwha satellite. The Mugungwha satellite that the proposed system should steer is a geostationary orbit device. The satellite-steering algorithm computes azimuth and elevation with reference to a stationary point on earth. This is extended to a real satellite steering algorithm that considers position and attitude. Real moving position and attitude are represented by latitude, longitude, roll, pitch and yaw. To apply these five pieces of information to the reference satellite steering algorithm, we introduce Euler's degree coordinates that express independently the rotation of each axis relative to an axis. There are two ways a basic algorithm of the antenna of a vehicle can track and orient to satellite. One way is a feedback loop method for broadcasting gain, while the other is a feedback loop method for position and attitude of a vehicle. In the present paper, we design a controller of satellite broadcasting system for a vehicle using an algorithm that combines the two methods. We performed a simulation and experiment to prove effectiveness.

COVID-19 vaccines have been developed worldwide in order to prevent the spread of coronavirus infection-19, but some people tend to refuse to be vaccinated against COVID-19. Therefore, we will investigate how people's understanding of COVID-19 vaccines affects their attitude to accept COVID-19 vaccination information. Therefore, the purpose of this study is to examine the determinants that affect the acceptability of COVID-19 vaccine through the informational characteristics of COVID-19 vaccine and the individual health belief theory. This study conducted an offline survey of 215 adult men and women living in Seoul and Gyeonggi-do Province during the period from September 1 to September 10, 2022, and we have conducted a final analysis using a total of 212 questionnaires. The results of our study were as follows. First, among the information characteristics of COVID-19 vaccine, it was confirmed that the amount of information had a significant positive effect on susceptibility, severity, and barriers in health belief theory, respectively. Second, among the information characteristics of COVID-19 vaccine, it was found that the quality of information had a significant positive effect on the susceptibility in health belief theory. Third, susceptibility and barriers in the health belief theory significantly had a positive effect on voluntary attitude and involuntary attitude in acceptance attitude, respectively. And finally, it was found that the severity of the health belief theory had a positive effect on the involuntary attitude in acceptance attitude. The results of this study suggest that policy efforts are needed to make accurate information about COVID-19 vaccine known to the people.

Since its launching on 21 December 1999, the Korea Multi-Purpose Satellite-I (KOMPSAT-I) has been successfully operated by the Mission Control Element (MCE), which was developed by the ETRI. Most of the major functions of the MCE have been successfully demonstrated and verified during the three years of the mission life of the satellite. This paper presents the operational performances of the various functions in MAPS. We show the performance and analysis of orbit determinations using ground-based tracking data and GPS navigation solutions. We present four instances of the orbit maneuvers that guided the spacecraft form injection orbit into the nominal on-orbit. We include the ground-based attitude determination using telemetry data and the attitude maneuvers for imaging mission. The event prediction, mission scheduling, and command planning functions in MAPS subsequently generate the spacecraft mission operations and command plan. The fuel accounting and the realtime ground track display also support the spacecraft mission operations.
