        OTT 플랫폼 스포츠중계에 대한 시청자 인식 분석 연구: 쿠팡 플레이를 중심으로

        장용석,김민준 한국스포츠학회 2022 한국스포츠학회지 Vol.20 No.3

        The purpose of this study is to intuitively grasp the perception of OTT platform sports broadcasting service by analyzing emotions and perceptions of sports broadcasting provided within the OTT platform, and furthermore, to present basic data for an activation strategy plan. . Text mining, entity name recognition analysis, opinion mining, semantic network analysis, connection degree centrality, and TF-IDF were conducted as research methods by using Textom, a social matrix big data analysis platform, and Ucinet6, a network analysis program. The research results are as follows. First, as a result of word frequency, TF-IDF, and connection centrality analysis, sports broadcast, Coupang Play, Soccer, Tottenham, Gyeonggi, Tottenham, Son Heung-min, Monopoly, League, and Coupang appeared in the top 10. Second, as a result of the eOpinion analysis, the positive rate was 79.92% and the negative rate was 20.08%, and it could be understood that the positive rate was higher than the negative rate. Third, as a result of the individual name recognition analysis, Son Heung-min, Jeong-gun, Lee Kang-in, Hwang Hee-chan, Hwang Ui-jo were found in the order. Fourth, as a result of CONCOR analysis, a total of three groups were formed: 'OTT platform sports content', 'OTT platform video service', and 'OTT platform overseas sports service'. It is hoped that the results of this study will lead to a positive policy on sports content services provided within the OTT platform. 본 연구는 OTT 플랫폼 내에서 제공되는 스포츠중계에 대한 감정 및 인식 등을 분석하여 OTT 플랫폼 스포츠중계 서비스 인식을 직관적으로 파악하고 나아가 활성화 전략 방안을 위한 기초자료를 제시하는데 본 연구의 목적을 두고자 한다. 연구방법으로는 소셜 매트릭스 빅데이터 분석 플랫폼인 텍스톰과 네트워크 분석 프로그램 Ucinet6를 활용하여 텍스트마이닝, 개체명인식분석, 오피니언 마이닝, 의미연결망분석, 연결정도 중심성, TF-IDF를 실시하였다. 연구결과는 다음과 같다. 첫째, 단어 빈도, TF-IDF, 연결 중심성 분석 결과, 스포츠중계, 쿠팡플레이, 축구, 토트넘, 경기, 토트넘, 손흥민, 독점, 리그, 쿠팡 등이 10위 권내에 나타났다. 둘째, 오피니언 분석결과 긍정비율은 79.92%, 부정비율은 20.08%로 나타났으며, 긍정비율이 부정비율보다 높게 나타난 것을 파악할 수 있었다. 셋째, 개체명 인식 분석 결과 손흥민, 정군, 이강인, 황희찬, 황의조 등의 순으로 나타났다. 넷째, CONCOR 분석 결과, ‘OTT 플랫폼 스포츠콘텐츠’, ‘OTT 플랫폼 동영상서비스’, ‘OTT 플랫폼 해외 스포츠서비스’로 총 3개의 그룹이 형성되었다. 본 연구결과가 OTT 플랫폼에서 제공되는 스포츠콘텐츠에 대한 정책이 긍정적인 방향으로 나아가길 희망한다.

        보골지(補骨脂)의 Peroxynitrite 제거 기전

        장용석,민건우,정지천,Jang, Yong-Suk,Min, Gun-Woo,Jeong, Ji-Cheon 대한한방내과학회 2004 大韓韓方內科學會誌 Vol.25 No.2

        Objective : Peroxynitrite $(ONOO^-)$, formed from the reaction of $O_2^-$ and NO, is a cytotoxic species that can oxidize several cellular components such as proteins, lipids and DNA. It has been implicated in the aging process and age-related disease such as Alzheimer's disease, rheumatoid arthritis, cancer and atherosclerosis. The aim of this study was to investigate scavenging activities of $ONOO^-$ and its precursors. NO and $O_2^-$ and its scavenging mechanism using fluorescent probes, DCFDA, DAF-2 and DHR 123.. Methods : Psoralea corylifolia was crushed. The crushed Psoralea corylifolia was extracted 3 times, each time with 3 volumes of methyl alcohol at $60^{\circ}C$ for 24 h. The extract was filtered and evaporated under reduced pressured using a rotary evaporator to yield 16g. This was done to investigate scavenging activities of $ONOO^-$, NO, $O_2^-$ and its scavenging mechanism using fluorescent probes, DCFDA, DAF-2 and DHR 123. Results : After Psoralea corylifolia was added authentic $ONOO^-,\;{\cdot}\;O_2^-$ and NO was markedly scavenged. Also, $ONOO^-$ induced by $O_2^-$ and NO (these derived from SIN-1) was inhibited. The data showed a decrease in $ONOO^-$ mediated nitration of tyrosine through electron donation after Psoralea corylifolia was added. Data showed a dose-dependent correlation with inhibition of nitration of bovine serum albumin induced by $ONOO^-$, Furtheremore, LPS-induced ROS and RNS generation was blocked. Conclusions: These results suggest potential for use of Psoralea corylifolia as an effective $ONOO^-$ scavenger to counter the aging process and age-related diseases.

        북한의 경제개선조치와 동북아 협력 : 동아시아 경제구조 변화와 남북경협

        장용석 평화문제연구소 2002 統一問題硏究 Vol.14 No.2

        The international environment of Inter-Korea economic cooperation is under deep change. The vertical international specialization in east asia which has been the engine of economic growth of this region in the past is transformed into the horizontal international specialization. It comes from the inflow of foreign direct investment from the advanced and the rapid growth of the high-technology industry in south-east asia including China. The regional economic integration like FTA has also strengthened. Hence, traditional comparative advantages have been obscured. The regional competition for the market of not only labor-intensive commodities but also capital and technology-intensive commodities has been highly intensified. It means that North Korea just passing the threshold of opening its door toward outside faces tough competition with China and south-east asian countries particularly Vietnam and the participation of the North into the world economy is more difficult than any other countries who opened their door in the past. On top of that, the North has many obstacles to attract foreign investment. First of all, the North has no advantages of low-wage, labor management and domestic demand especially compared to China and Vietnam. The North is also under serious economic constraints of the United States. The commodities made in D.P.R.Korea are hardly exported to the United States which is one of the largest market in the world due to high customs imposed on the commodities from the hostile countries. The equipments and technologies which are originated from the Unites States and have the possibility being used for military purposes cannot be imported to the North. Due to above mentioned reasons, the North cannot recover its seriously depressed economy for itself. Consequently, to recover the economy of North Korea and develop balanced national economy in the Korean peninsular, a comprehensive plan for economic development based on the premise of coexistence with North Korea is urgently necessitated. While acknowledging that great attention ought to be given to the way to build inter-Korea specialization which has international competitiveness, the increase of residents`` income and the expansion of the domestic market in the North should be the principle of this plan. It is essential to the renewal of the regional industries and eventually preventing the deindustrialization of the North being anticipated in the future process of inter-Korea economic integration.

        덕유산의 천연생 주목나무림 식생구조

        장용석,양덕춘,정동준 한국자원식물학회 2004 한국자원식물학회지 Vol.17 No.1

        This study was carried out to investigate the structural characteristics of Taxus cuspidata communities in Mt. DuckYoo. The vegetation was consisted of 20 species in the T1(tree) layer, 26 species in the T2(subtall tree)layer, 26species in S(shrub) layer, and 56 species in the H(herb) layer. The dominant species of Mt. Duckyoo was Taxus cuspidata in the T1 Layer, Acer tschonoskii var. rubripes in the T2 Layer, Tripterygium regelii and Acer tschonoskii var. rubripes in the S Layer and Sasa borealis in the H Layer. According to the diameter distribution of high ranking five species in T1, T2 layer at natural Taxus cuspidata communities, these forests may be gradually replaced by Quercus mongolica, Tripterygium regelii. The composition of biological type was Ph-D1-R5-e.
