Recently, as the transition to the untact era due to COVID-19 accelerates, non-face-to-face and non-contact practices have become commonplace, and the OTT (Over-The-Top) service market that provides media content such as movies and broadcast programs through the open Internet is largely expanded and it is receiving great attention from the MZ generation, who are familiar with digital devices and environments. In this study, the effects of OTT service characteristics on MZ generation users' flow, satisfaction and brand loyalty were examined, focusing on Netflix users, one of the representative OTT service brands. In order to carry out this study, a total of 216 people who have used the Netflix OTT service platform were empirically verified by using the survey data of those who have used it for analysis. As a result of the analysis, it was found that among the characteristics of OTT service, contents diversity, convenience, and reliability had a positive (+) effect on flow. Also, flow has a positive (+) effect on satisfaction, and satisfaction has a positive (+) effect on brand loyalty. However, among the characteristics of the OTT service, the recommended service did not have a positive (+) effect on the flow, and the flow did not have a direct positive (+) effect on the brand loyalty. Flow had a positive (+) effect on the brand loyalty through satisfaction. Through this study, it is expected that the market revitalization of the OTT service-related industry and the increasing number of OTT service brands will be able to contribute to the establishment of marketing strategies for the MZ generation consumers, and to provide practical implications.

To establish a generation acceleration technique, two crops a year at field condition of Suweon, 10 varieties different in their spring growth habit were tested with 6 different seeding time after harvesting. These materials were harvested on June 10, 19, 79 and tested for their seed production ability at varions seeding time from July I I to August 15 with a week interval. An immatured seed germination technique and green vernalization methods were applied in cycling generations and the results obtained were summarized as follows. 1. In summer growing, seedlings establishment after transplanting was better in earlier transplanting. 2. Heading time was remarkably enhanced by earlier transplanting. Considering the results of two years early or mid of July was the suitable time to plant the second summer crop. 3. Those varieties of spring growth habit expressed little variations in plant height among the varieties. In 1978 which is referred as warm year produced plant height as tall as 8-16cm and poor crop but produced good crop with 25-65cm plant height in 1979. 4. No definit tendency in the length of spike was. observed among the cultivars but longer spike was found in winter wheat compared to the spring. 5. Number of spikes per plant was ranged from 1 to 3 regardless the transplanting time in 1979. However, more spikes per plant were produced in early or mid of July transplanting and those varieties of higher growth habit than V did not produces any spikes. 6. Higher number of grains per spike was found at earlier transplanted varieties. Therefore, it is concluded that those materials of I-IV growth habit with mid or early July transplanting would be suitable in practical sense considering their ability of seed production. 7. Two-year results indicated that wheat crop can not tolerate the temperature level higher than average 32$^{\circ}C$ C at Suweon. In this regard, the cultivation schedule was established assuming average temperature condition like the year of 1979 which was possible to grow wheats.

The 4th industrial revolution refers to the next-generation industrial revolution led by information and communication technologies such as artificial intelligence (AI), Internet of Things (IoT), robot technology, drones, autonomous driving and virtual reality (VR) and it also has made a significant impact on the development of the advertising industry. However, the world is rapidly changing to a non-contact, non-face-to-face living environment to prevent the spread of COVID 19. Accordingly, the role of the 4th industrial revolution and advertising is changing. Therefore, in this study, text analysis was performed using Big Kinds to examine the 4th industrial revolution and changes in advertising before and after COVID 19. Comparisons were made between 2019 before COVID 19 and 2020 after COVID 19. Main topics and documents were classified through LDA topic model analysis and Word2vec, a deep learning technique. As the result of the study showed that before COVID 19, policies, contents, AI, etc. appeared, but after COVID 19, the field gradually expanded to finance, advertising, and delivery services utilizing data. Further, education appeared as an important issue. In addition, if the use of advertising related to the 4th industrial revolution technology was mainstream before COVID 19, keywords such as participation, cooperation, and daily necessities, were more actively used for education on advanced technology, while talent cultivation appeared prominently. Thus, these research results are meaningful in suggesting a multifaceted strategy that can be applied theoretically and practically, while suggesting the future direction of advertising in the 4th industrial revolution after COVID 19.

인터넷의 도입 및 확대가 활발하게 이루어지면서 보다 많은 이용자들은 홈 네트워킹 기반의 정보 가전 기기, 텔레매틱스, 전자 물류 실현을 위한 전자 태크(RFID), 센서 네트워킹 등 모든 사물이 상호 통신할 수 있는 다양한 서비스를 요구하고 있으며 이를 해결하기 위한 연구가 활발히 진행되고 있다. 그러나 현재인터넷의 기반이 되고 있는 IPv4 주소 체계는 약 43억 개의 주소를 생성할 수 있도록 설계되어 있으며, 그 동안 비효율적인 주소 할당으로 유효한 주소는 불과 5~6억 개 정도만을 사용할 수 있는 실정이다. IPv4 기반의 인터넷 주소 체계로는 앞으로 도래할 유무선 통합 서비스 혹은 방송과 통신이 융합되는 사용자 중심의 인터넷 서비스 네트워크 구축에 많은 문제점을 갖고 있기 때문에 주소 자원을 거의 무한대로 제공하는 IPv6 기반의 인터넷(128비트 IPv6 주소는 2128개의 주소 지원) 도입이 필수적이다. 따라서 현재 IPv4 기반의 인터넷에서 IPv6 기반의 차세대 인터넷으로 전환되고 있으며, 또한 라우터 장비 시장은 차별화된 IPv6 기능을 제공하는 장비 중심으로 재편될 것으로 보인다. 본 고에서는 IPv6 라우터에 대한 IPv6 도입 배경 및 프로토콜에 관련된 제반적 기술을 살펴 보고, 이를 기반으로 외국 시스템들의 현재 구현 상태, IPv6 라우터를 개발하는 데 연구되어야 할 주요 사항 및 국내외 IPv6 도입 추진 현황을 살펴 본다.
