이 연구의 목적은 온라인 상에서 수행된 실습 수업 방식을 분석하는데 있다. 이를 위해 연구자는 예비 교사를 대상으로 '전기 자동차 만들기'수업 주제로 실습 수업을 설계하였으며, 온라인 동영상 강의 컨텐츠 3편을 제작하였다. 동영상 강의 컨텐츠 제작을 위해 교수용 홈페이지 제작, 수업에서 사용할 동영상 제작, 과거 촬영하거나 제작해 두었던 동영상 준비, 실습 재료 준비, 실습 활동 관련 교과서 준비 등 다양한 교수학습자료를 사전에 준비하였다. 동영상 강의 컨텐츠는 CODTRA 분석 방법을 이용 하였으며, 분석 코드는 '동영상에서 제시된 교수학습자료'와 '교수자가 행하고 있는 상태'이었다. 분석 결과는 CODTRA 다이어그램에 의해 분석 코드를 시간에 따라 도식화하여 도시하였다. 이 연구 결과는 중등학교의 기술 교과나 공업계 교과에서 온라인 실습 수업을 위한 동영상 강의 컨텐츠를 제작하고자 하는 교수자에게 참고할 수 있는 자료로 활용될 수 있을 것이다.

5G 서비스가 공식적으로 시작되었다. 아직까지 서비스 개시 초기 단계이다 보니 서비스 제공 지역(coverage)이 제한되어 있다거나 통신품질이 안정적이지 않다는 등의 이슈가 존재하기는 하지만, 이러한 문제들은 시간이 지나면 충분히 해결될 수 있을 것으로 기대된다. 따라서, 지금 우리에게 중요한 것은 5G가 제공하는 특성을 제대로 이해하고 이를 활용한 서비스들을 차근차근 준비함으로써 새로운 기회를 준비하는 것이라고 생각한다. 그런 이유로 이 글에서는 5G 서비스의 주요 구현 기술들에 대해 소개하고 이해를 도움으로써 방송 및 미디어 사업자를 포함한 다양한 산업분야의 서비스 사업자들이 5G 특성을 제대로 활용한 서비스를 준비할 수 있도록 하고자 한다. 그렇다고 해서 5G 서비스를 가능하게 하는 다양한 기술들을 모두 소개할 수는 없으므로, 고속, 저지연, 대용량 특성과 이들을 효과적으로 사용할 수 있도록 하는 네트워크 슬라이싱과 관련된 기술들을 중심으로 소개하고자 한다. 또한, 5G 서비스가 제공하는 특성들로 인한 비즈니스 모델의 변화에 대해서도 함께 생각해 보고자 한다.

This study seeks to investigate the mediating effect of career identity in the structural relationship between career anxiety, career stress, career identity, and career preparation behavior. Based on these results, we provide basic data for students' career guidance and career education. For this purpose, data were collected and analyzed targeting third-year commercial high school students preparing for their careers. As a result of the analysis, it was found that as career anxiety increases, students' career stress increases. However, career anxiety was found to have no direct effect on career identity and career preparation behavior. Second, career stress was found to have a significant impact on career identity and career preparation behavior. Third, the mediating effect of career identity was found to be high in the relationship between career stress and career preparation behavior. This shows that career stress increases actions for career preparation through career identity.

국제표준화 단체 MPEG과 VCEG이 연합하여 만든 기구인 Joint Video Explorer Team (JVET)은 Versatile Video Coding (VVC)/H.266 완성 이후, 새로운 표준을 준비하기 위한 차세대 코딩 기술을 연구하기 시작하였다. 두 가지 큰 연구 방향이 설정되어 스터디가 진행 중인데, 하나의 방향은 기존 코덱에서 많이 활용되었던 신호 처리 기반 기술 연구이고, 다른 방향은 신경망을 활용하여 새로운 코딩 기술을 연구하는 것이다. 신경망 기반 비디오 코딩은 표준화에서 공식적으로 연구된 적이 없으며, 해당 시도는 차세대 표준을 준비하기 위해서 처음으로 하는 시도이다. 본 기고에서는 비디오 코딩 표준의 새로운 방향에 대한 통찰력을 제공하기 위해 JVET에서 새롭게 시작되고 있는 신경망 기반 비디오 코딩 연구에 대한 동향을 리뷰하고자 한다.

역대 엑스포의 내용과 성과 널리 알려져 있듯이 엑스포(EXPO)는 그 준비에 있어 고도의 기술능력과 막대한 재원이 요구되는 까닭에 선진국의 전유물이 되어 왔다. 개발도상국 최초의 엑스포를 준비하는 지금, 역대 엑스포의 내용과 성과를 새롭게 짚어본다면 우리에게는 값진 교훈이 될 수 있을 것이다.

This report addresses the question whether resilience affects attitudes of middle-aged employees toward retirement. Are resilient employees more prepared and/or ready for retirement? To address this question, a survey of over 214 employees aged 50 or more was taken. Participants worked in the Seoul metropolitan area. This study utilized the SPSS 19.0 program. A sophisticated regression analysis software system was conducted to measure and identify relationships and correlations among groups of participants. Our findings included four points. First, male employees were better prepared for retirement than women. Second, the more educated (or the higher the household income), the better prepared was the participant for retirement. Third, the more resilient a worker was, the less was the resistance expected from him/her on retirement. Finally, a positive attitude was an indication the worker would be well-prepared for retirement. In summary, workers who displayed resilience and a positive attitude in their work were best prepared for retirement.

The purpose of this study was to investigate major selection motivation, major satisfaction, nursing professionalism, and career preparation behavior as well as identify influencing factors on the career preparation behavior of nursing students. The data were collected using questionnaires filled out by 208 nursing students in their junior and senior years at two universities in Jeollanam-do and Gyenggi-do, from November 1, 2018 to December 20, 2018. Data ware analyzed by using the SPSS Win 22.0 program (frequency, ANOVA, Pearson's correlation, and multiple regression analysis). The mean score of career preparation behavior was 2.74±0.70 (range:1-5). There was a significant positive correlation between major satisfaction, nursing professionalism, and career preparation behavior. For the multiple regression analysis, meaningful variables that significantly influenced career preparation behavior were nursing professionalism and general characteristics (grade, career preparation period). These factors explained 21.5% of the variance. Improvement of the above meaningful variables allowed better career preparation behavior. The results show that among students with weak meaningful variables, improvement of the above meaningful variables can improve job preparing behavior. In order to improve career preparation behavior, a career preparation program should be developed that reflects meaningful variables.

This study recruited adults aged 35 to 64 living in Daegu and Gyeongsang buk-do to analyze the images of the elderly perceived by the mid and older- aged adults and their preparation for later life. The results of this study are as follows: First, as for the images of elderly people recognized by the research subjects, psychological images were the most positive, followed by physical and social images. Those with a higher education level, full-time job, and parents alive had more positive images of the elderly. The psychological images were better in those married compared to singles or divorcees, and the higher the age considered as elderly, the better the psychological and social images of the elderly. Second, preparation for later life in the mid and older-aged adults was better in order of emotional and physical preparation, whereas economic and leisure and social preparation were not enough. Those who are female, those with a higher education level, higher average monthly household income, professional job, and full-time job, and those who have an older age in mind as a definition of elderly have been better prepared for later life. Third, it was found that the sub-factors of their images of elderly people and preparation for later life affected each other, and the more positive their images of elderly people, the better they had been prepared for later in life. The results of this research suggests a desirable direction for improving the images of the elderly, implicating the necessity of exploring measures to provide individual and social support and developing educational programs for successful life after retirement.

This study investigates the effects of the degree of preparation engaged in the related industry, and the amount of financial support program on R&D performance of technology based startup companies. This study seeks to discover the core variables that impacts most on business performance. However, it should be noted that the validity of such variables and their impacts on business performance can be contentious. The study sets hypothetical variables as following. Intensity of preparation of the startup company, amount of preparation and amount of work experience in related industry are independent variable. The amount of financial support program was selected as a moderating mediating variable. According to the results, the intensity of preparation had a positive relationship with R&D performance, as opposed to work experience of the founder having a negative relationship on R&D performance. The amount of support program had no significant relationship with R&D performance. Furthermore, there are negative modified effect between the amount of support program and work experience. And, there is no relationship modified effect between support program and work experience. Existing policies tend to lean heavily toward young entrepreneurs through support and guidance. The government has placed great emphasis on policies that aim to promote and create jobs for young individuals. The results suggest that the government should review their policies toward young technological entrepreneurs and that these entrepreneurs should prepare thoroughly before launching any startups.
