With the spread of digital trade, the share of digital trade under the global trade environment is increasing. However, since there is no international digital trade standard, the discussion to establish a new trade rule has important significance. Countries around the world are implementing digital trade policies in consideration of their own interests, but different regulatory policies are causing trade conflicts. In order to provide safeguards against personal information infringement due to the free movement of data across borders, major countries around the world have taken measures to localize data, and the EU has enacted GDPR. And the United States regards the imposition of the digital tax as a trade barrier, and some countries oppose the implementation of the digital tax for fear of negative impact on their countries. However, discussions on the global digital tax, centered on the OECD and the G20 are making progress. As it is highly likely that a digital tax agreement will be drawn up within this year, countermeasures must also be prepared. Therefore, this study presents implications for the future direction of Korea's trade policy by examining recent trends in digital trade norms and analyzing major issues in digital trade.

본 논문에서는 ITU-R M.1798-1 에 기반한 해상 HF 데이터 통신을 위한 세 가지 종류의 디지털 통신 방식을 소개하고 비교한다. 처음 두 개의 시스템은 3 kHz 대역폭을 사용하는 디지털 통신 방식으로서 OFDM 방식과 멀티 톤 방식의 디지털 모뎀이며, 마지막 세 번째 방식은 10-20 kHz 의 대역폭을 사용하는 OFDM 방식의 디지털 통신 모뎀이다. 본 연구를 통하여 각각의 통신 방식에 대한 물리계층 규격을 비교 분석한다.

2002년은 다음의 '온라인 우표제'와 프리챌의 '커뮤니티 유료화' 그리고 소리바다 '불법 판결', 엔씨소프트의 '영등위 심의'등으로 정부와 업계, 업체와 업체간, 그리고 업체와 네티즌 간 이해관계에 따라 의견이 엇갈린 한 해였다. 다음 '온라인 우표제'는 업체들의 반발에도 불구하고 자리를 잡았고, 프리챌은 아직도 네티즌 끌어안기에 부심하고 있다. 2002년 마지막 화두였던 엔씨소프트의 리니지 18세 이상가 판정은 엔씨소프트의 영등위 설득 노력으로 15세 이상가 판정을 받으며 마무리되었다. 2003년은 업체와 네티즌 모드 윈-윈 할 수 있는 '수익모델'과 '새로운 서비스'가 선보이길 기대하며, 디지털콘텐츠 산업 분야에서 '온라인게임', '온라인교육', '인터넷음악', 'e-Book' 분야의 이슈를 정리해 보았다.

The purpose of this research is particle shape evaluation of granular soil and aggregate using Digital Image Process(DIP). DIP is very useful to measure the roughness and particle shape of aggregates. Couple of aggregates, like standard sand, two different crushed stones, and two different marine aggregates, have been employed. Shape factor of two different marine aggregates is ranged 0.35 to 0.54. Crushed stone I is that of 0.74 which is highly flat, but standard sand is elongated shape. Especially, two marine aggregate showed a big difference of width and length which meaned a long shape. There is any significant difference of elongation ratio and flakiness for each aggregate with different measuring system, like direct measurement of vernier calipers and DIP method. Within the limited test results, DIP is one of useful to get the particle shape of aggregate with limitation of measuring errors and to apply the particle distribution curve.

The purpose of this study was to investigate the elaboration strategy associated with multimedia learning for children. Main subjects of this study, which were 157 eight-, 150 ten- and 152 twelve-year-old children(total: 459). As a result, the elaboration strategy could find the facts to be effective to twelve-year-old children. And the elaboration strategy at cognitive style was not significant. We would suggest that the age is a significant variable to apply the elaboration strategy in multimedia learning.

The purpose of this study is to verify the influence relationship of digitally converted services on consumers' intention to use since traditional services are being converted to digital services due to technological development and increase in non-face-to-face services. The study consisted of a program development procedure and a program effectiveness verification procedure, and bootstrapping was performed to verify the mediating effect adjusted along with multiple regression analysis. The subjects of this study were 323 university (graduate) students and the general public residing in Korea. Results. First, it was found that the three perceived interaction factors (perceived communication, perceived control, and perceived reactivity) of digital transformed services had a positive effect on perceived usefulness and perceived ease of use, respectively. Second, the relationship of influence of technology acceptance intention was verified. Third, it was confirmed that the effect of the three perceived interaction factors of digital transformed services on intention to use was mediated by perceived usefulness and perceived ease of use. Fourth, the mediating effect mediated by digital disparity was confirmed. As a result, it was confirmed that the three perceived interaction factors of the digitally converted service are important factors in the intention to use the digitally converted service. This suggests that efforts are needed to minimize the digital divide.

In the digital world, creative industries such as music, movies, and drama have been the most impacted by digital transformation. As these contents were converted to a digital format of 0s and 1s, the business model changed and so did the rules of competition in the market. Apple, Spotify, and Netflix were quick to ride the digital transformation wave to become market leaders in the creative industry. This study reviews case studies in the creative industry to grasp the important factors necessary for market restructuring using digital technology. It was found that companies that set visions, platform, and open innovation as business strategies were able to achieve critical mass and become market leaders. These three elements are commonly found in the contents industry. On the other hand, companies that did not embrace digital innovation have become victims of digital darwinism. By analysing the experience of digital product innovation through case studies in the creative industry, we can derive implications for digital transformation in the 4th industrial revolution.

In this paper, I tried to apply the viewpoint and the method of "Cultural Study" to the analysis of a Architecture. "SE HAN DO(歲寒圖/ Jeonghee Kim 金正喜/ 1844)", the masterpiece of the "literary artist's paintings"(文人畵) is used as a 'TEXT‘(: parole) and analysed to show how artist's value and social-cultural ideology (as a 'CONTEXT':langue) are projected to the space and architectural vocabulary.

1999년 한해 국내 각 필름 업체는 본격적인 마케팅에 뛰어들어서 가격 경쟁을 벌였으며, 전년 대비 $20\%$ 이상의 매출회복세를 이룬 것으로 알려졌다. 일부에서는 디지털 제품 보급의 급신장으로 전통사진의 위상이 축소될 것이라는 우려가 있으나 관계자들은 오히려 디지털사진과의 접목을 통해서 시장이 더욱 밝아질 수도 있다고 전망한다.
