최근에 정보 고속도로 사업계획과 관련하여 세계 여러나라들이 실시하거나 실시 예정인 VOD 시험서비스에 많은 관심이 일고 있다. VOD서비스와 같은 대화형 TV 서비스(I-TV, Interactive-TV Service)는 컴퓨터, 통신 가전업체 그리고 영화 제작사등이 함께 참여하고 있다. 본 기고에서는 차세대 통합 멀티미디어 사업이라는 대화형 TV서비스의 개요와 요소기술, 그리고 서비스의 동향 및 전망을 알아보기로 한다. 1. 대화형 TV 서비스(Interactive TV Service)의 개요 현재까지 대부분의 TV 시청자들은 방송국으로부터 송신되는 공중파나 CATV서비스를 통해 프로그램 서비스를 받아보는 방송(broadcasting)방식 형태의 서비스를 이용해 왔다. 그러나 이러한 일방적인 수신방식은 최근 미국의 클린턴 행정부가 미국의 차세대 기반 통신망 구축 정책(정보 고속도로 사업; Information Super High-way)의 일환으로, CATV 사업자뿐만 아니라 지역 전화회사까지도 참여하고 있는 VOD(Video On Demand) 시험서비스가 시행됨에 따라서 미국은 물론, 우리나라를 비롯한 여러나라에서 대화형식의 TV서비스를 시행하려는 움직임이 일어나고 있다. 이러한 움직임은 지난 ‘92년 7월 16일 미 연방통신위원회(FCC. Federal Communication Committee)가 그동안 전화회사에 대해 CATV 시업진출을 금지하였던 정책을 바꿔서, CATV에 대항한 경쟁도입과 기반 정보통신망 정비를 목표로 하여 비디오 다이얼톤(VDT(주), Video Dial Tone)이라는 이름하에 공중통신 사업자에게도 영상신호를 전송을 인가함에 따라 시작되었다. VOD서비스와 같은 대화형 TV서비스는 가입자가 원하는 서비스를 시간에 관계없이 댁내의 통신회선(일반전화망, 케이블망, 광화이버망, 위성망)을 통해서 요구 즉시 실시간에 서비스를 받아볼 수 있는 멀키미디어의 통합서비스 방식이다. 도한 이 서비스는 음성통신과 방송의 통합형 서비스로서, 방송국, 전화회사 혹은 서비스 제공업자(ISP ; Information Service Provider)에 의해 제공된 디지탈 영상 및 일반 데이터 등을 압축하여 서버에 저장한 후, 소비자의 요청이 있을 경우에 통신회선을 통해 즉시 서비스 해준다. 이와 같은 대화형 TV 서비스의 구성요소로는 다양한 영상정보 및 데이타를 보유하고 있는 정보제공자, 전화선이나 CATV 또는 위성방송과 연결해 주는 지역별 비디오 서버 및 교환장치, 통신회선을 통해 전송된 서비스를 영상정보로 만들어주고 또한 가입자의 요구를 즉시 정보제공자에게 알려줄 수 있는 가정용 단말기 (STB. Set Top Box)로 이루어진다. 여기서, 비디오 서버는 다양한 대화형 TV 서비스를 제공해 주는 중계자로서, 영화, 홈쇼핑, 홈뱅킹, 대화형 교육, 비디오 게임 등을 가정에서도 가능하게 해 줄 뿐 아니라, 가입자를 관리하는 기능을 가지고 있어서 가입자 정보는 물론, 각종 서비스 사용료, 개인 통계자료 분석 등도 집계할 수 있는 기능을 가지고 있다.(그림1) 본 기고에서는 이러한 대화형 TV서비스 중에 대표적 응용서비스인 VOD 서비스에 사용되는 기술요소와 각국에서 진행되고 있는 VOD 서비스 동향 및 전망에 대해 알아보고자 한다. (주) VDT(Video Dial Tone) : FCC가 ‘92년 7월 16일에 인가한 지역 전화회사에 의한 가정용 영상 전송서비스 및 CATV에 대항한 경쟁도입과 Infrastructure의 정비를 목표로 하여 결정한 내용은 다음과 같다. 지역 전화회사에 대하여 (1) 공중통신사업자에 대하여 서비스 제공자에 대한 영상신호의 전송을 인가(기본서비스), (2) Video Gateway 서비스, 비디오 기기 제공, 서비스 제공사업자에 대한 과금, 요금징수 대행을 인가(고도서비스), (3) 프로그램 제공자에 대하여 자본출자율을 5%로 높이는 외에 (종래는 1%) 업무 관계의 확대(합병회사 설립 및 consultant 계약 등)를 인가. (4) Rural 지역(영업지역의회의 지방)에 대한 직접 프로그램 제공의 특별인가(주민이 1만세데 미만의 지방 공공 단체만 가능, 영업지역내에서는 제한없음), (5) 지방공공 사업체에 의한 영업면허의 불요(지역 전화회사가 직접 사용자에 서비스를 제공하지 않기 때문에 CATV 서비스로는 보지 않기 때문). (6)의 회로의 권고(케이블 정책법으로 결정되어 있는 통신사업자와 CATV회사 자본의 상호보유 금지의 해제) 등이다.

In this paper, I will critically assess E. Wilson's concept of consilience and thereby try to show the proper way that the humanities and the natural sciences could meet each other and carry out various kinds of interdisciplinary research. In section 1, I will delineate Wilson's concept of consilience. It is the core of his project of consilience to unify the humanities and the natural sciences through the natural scientific methods and therefore he claims that it is in principle possible to carry out the project of consilience. In section 2, I will examine the basic structure of knowledge in the humanities and show that, in principle, the project of consilience cannot be carried out. In section 3, I will show the difficulties that Wilson's projectof consilience has with respect to carrying out the interdisciplinary research between the humanities and the natural sciences. In section 4, I will deal with the various types and ways of properly carrying out the interdisciplinary research between the humanities and the natural sciences. In section 5, I will show that Wilson's concept of consilience has some more difficulties that are not to be discussed in detail in this paper. We also need to critically assess them in order to prepare a more solid ground for the interdisciplinary research between the humanities and the natural sciences.

This case study examined whether a cooperative musical instrument playing could enhance interactions between children with autism spectrum disorder (ASD) and their neurotypical (NT) siblings. It involved three children with ASD aged 7-12 years and three NT siblings aged 6-11 years. Each group, comprising a child with ASD and their NT sibling, participated in a 40-minute sessions twice weekly for eight sessions over four weeks. The intervention included three stages: simultaneous action, complementary action, and achieving a joint goal. Evaluation criteria included the initiation and response behaviors of each child, and sequential interactive behaviors and cooperative behaviors between pairs were measured. Additionally, before and after the intervention, parents and NT sibling assessed their perceived sibling relationships. Results showed increased interactive and cooperative behaviors. Post-intervention, both parents and NT siblings rated the sibling relationship highly, despite little change in sibling conflict and competition consciousness. These findings indicate that interactive instrument playing can enhance perceptions of siblings as cooperative play partners and aid in teaching them how to collaborate during interactions.

In this study, we tried to secure basic data to create an environment necessary for distance learning through a survey on professor demand. Among the 184 full-time faculty members of the university, 73 (39.89%) respondents in 2021 and 87 (47.28%) in 2022 were included. As a result of the research on professor demand, in the 2021 school year, 27 people (37%) were classified as LMS improvement items when checking attendance, 38 people (23.3%) were pin-mics as content development support items, and 26 people (35.6%), 33 people (45.2%) of GOM Mix and 25 people (34.2%) of the distance education support center wanted to learn video editing program as the item of video editing program they are currently using. In the 2022 school year, 27 people (31.03%) said mobile upgrade as an LMS improvement item, 52 people (59.8%) of pin-microphone as a content development support item, 33 people (37.9%), but currently using the content creation intention using a studio. As for the video editing program they are working on, 47 people (54%) of GOM Mix Pro and 23 people (26.4%) of the distance education support center want to learn content creation method. In addition, the intention to produce content using the studio for the 2021 and 2022 academic year and the desired educational topic of the distance education support center in the future appeared insignificant (p > 0.05). In this distance education support center, we are working to solve the class of LMS attendance, upgrade mobile, and plan to distribute pin microphones. We are planning to increase the usability of the studio and provide training on how to use video editing programs and how to create video content. In order for a smooth class to take place in a university distance class, the university authorities should seek ways to support the instructor so that he/she does not have difficulties in performing his/her role as a teaching designer, such as setting learning goals, organizing and organizing content, motivating learning, and establishing effective class participation plans. there is a need

In this study, we investigated the thinking processes of 7th grade science-gifted students in designing application experiments and analyzed their performance levels in the categorized processes. The analyses of the results revealed that they considered 'setting a problem situation,' 'deciding a strategy,' 'identifying the assumptions,' 'defining the measurements,' and 'validating the assumptions' in the processes of designing experiments. However, their performance levels of the categorized processes were found to be rather low. It was especially insufficient in setting the situations concretely appropriated to solve the problems and checking their own thinking critically by proper criteria. Therefore, we suggested a potential learning strategy for designing experiments such as replacing difficult and abstract situations to concrete and familiar situations. These results may offer some implications in developing an education program for science-gifted students to foster creativity by emphasizing scientific thinking skills such as experiment design ability.
