The purpose of this study is to investigate Chinese Internet video users about their attitudes toward and their impact on in-stream advertising in Internet video. In addition, the effect difference between the Internet video interface and the in-stream advertising attitude and ad-hiding was identified depending on the type of content. According to the research, Hypothesis 1 defines how the degree of Internet video information in which users use Internet video affects the attitude of the in-stream advertisement in that Internet video. The analysis results showed that the p value was .133 and the variable was not significant at the significant level. Hypothesis 2's in-stream advertising attitude has a significant effect on an in-stream advertising hedge. The results showed that the in-stream advertising attitude has a significant negative (-) effect on the in-stream advertising hedging. In cases where users have a good attitude toward in-stream advertising from Internet video clips, less ad-hiding behavior has occurred for in-stream advertising has occurred. Therefore, Hypothesis 2 was adopted. Hypothesis 2a confirmed that the degree of in-stream advertising to skip from the in-stream advertising attitude to the extent of the in-stream ad-happiness is different from those to the extent of which the in-stream advertising And we found that in the case of in-stream ads that could skip over in-stream ads that could not be skipped, there were more actions of in-stream ad hedging. Thus, Hypothesis 2a was adopted. Whether the Internet video of Hypothesis 3 has a significant effect on an in-stream advertising hedge has been identified. The results showed that Internet video content has a significant positive effect on ad hedging. It is said that when the user has a higher level of interest in the Internet video, he or she is more likely to avoid the in-stream ads from the video. Therefore, Hypothesis 3 was adopted. Hypothesis 4 validated the medium effect of the in-stream advertising attitude in the relationship between the internet video audience and the in-stream advertising hedging. As a result of the Sobel test, the mediating effect of the in-stream advertising attitude in the relationship between the Internet video audience and the in-stream advertising hedge was 4.7473, which was greater than 1.96, showing statistically significant results under the significant level of 0.05 . Therefore, Hypothesis 4 was adopted. Hypothesis 5 identified how Internet video aggregations for seven types of movies, genre drawings, news, education, physical education, dramas, and other types of content affect the attitude of the in-stream advertising. As a result, there is only one significant variable in physical education and cannot be compared between variables. Internet video content for six types of content, including movies, genre drawings, news, education, drama, and other types of content, did not have a significant impact on the mainstream advertising attitude. Hypothesis 6 identified how Internet video aggregations for seven types of movies, genre drawings, news, education, physical education, dramas and other types of content affect in-stream ad-happiness The results showed that the variables for the final four types of content were not significant. And three variables - movie, physical education and drama - were found to have had a significant impact. Looking at the order of influence, it appeared in the order of physical education, drama, and film. In other words, it was confirmed that the impact of Internet video content on an in-stream ad hedging will vary depending on the type of content. And among the types of content, Internet video on physical education has a greater impact on the in-stream ad-happiness. Thus, Hypothesis 5 was adopted. 본 연구는 중국 인터넷 동영상 이용자들을 대상으로 인터넷 동영상에 선제적으로 등장하는 인스트림 광고에 대한 태도 및 인스트림 광고회피에 미치는 영향에 대해 조사할 목적을 가진다. 또한 콘텐츠 유형에 따른 인터넷 동영상 인게이지먼트와 인스트림 광고태도 및 광고회피의 관계에 있어서의 효과차이를 규명하였다. 연구결과에 따르면 인스트림 광고태도는 인스트림 광고회피에 유의한 부(-)의 영향을 미치는 것으로 나타났다. 또한 인스트림 광고태도는 건너뛸 수 없는 광고와 건너뛸 수 있는 광고는 인스트림 광고회피 정도에 있어서 차이가 있는 것을 확인하였다. 그리고 인터넷 동영상 인게이지먼트가 광고회피에 유의한 정(+)의 영향을 미치는 것으로 나타났다. 마지막으로 인터넷 동영상 인게이지먼트가 인스트림 광고회피에 미치는 영향은 콘텐츠 유형에 따라 달라진다는 것을 확인하였다.

인지무선 라디오 기술을 이용한 효율적인 GSO 위성망 주파수 공유방법

정원식,장성진,조재범,김재명 통신위성ㆍ우주산업연구회 2010 한국위성정보통신학회논문지 Vol.5 No.2

최근 다양한 무선통신 기기의 등장 및 멀티미디어 사용자의 증가와 함께 주파수의 효율적인 관리가 중요한 문제로 떠오르고 있다. 위성 시스템이 가지는 주파수 자원은 매우 높은 가치를 지니며 희소할 뿐만 아니라, 넓은 커버리지를 가지기 때문에 효율적인 통신 자원 관리를 위해서 지상 시스템과의 주파수 공유는 필수적이다. 최근 위성망을 공유하는 방법으로 제안된 최소이격거리를 사용한 고정 지상국 배치 기법은 지상국 송신 전력의 경로 손실만을 고려한 간섭 경감 기법이기 때문에 위성망 주파수를 공유하는 방법이 되기에는 매우 비효율적이다. 따라서 본 논문에서는 일반적인 지상 시스템이 아닌 유전자 알고리즘 기반의 인지무선 라디오 기술을 사용한 효과적인 위성망 공유 방안을 제안한다. 제안된 인지무선 라디오 기술은 지상국 스스로 위성망에 대한 간섭을 계산하고 전력을 조절할 수 있기 때문에 기존의 고정 지상 시스템보다 지구국에 대한 지상국들의 간섭을 효과적으로 줄일 수 있을 뿐만 아니라, 더 많은 지상국의 위성망 주파수 공유가 가능해 진다.

Men With Severe Lower Urinary Tract Symptoms Are at Increased Risk of Depression

정원식,최홍용,남지원,김신아,최보율,문홍상,김규식 대한배뇨장애요실금학회 2015 International Neurourology Journal Vol.19 No.4

Purpose: Lower urinary tract symptoms (LUTS) comprise a set of common, bothersome symptoms in middle-aged and elderly men. Recent research suggests that depressive symptoms may influence the symptoms of benign prostatic hyperplasia (BPH). We performed a community-based cross-sectional study to evaluate the correlation between LUTS and depression. Methods: The survey was conducted in a rural community during four periods in August 2009, 2010, 2011, and 2012. Two validated questionnaires were used to examine LUTS and depressive symptoms. These included the International Prostate Symptom Score/quality of life (IPSS/QoL) and the Korean version of the Center for Epidemiological Studies-Depression scale (CES-D-K). Patients were categorized in the depressive symptom group if their CES-D-K score was >16 points. Results: A total of 711 men were included in this study. Thirty-five participants (4.92%) were found to have depressive symptoms. There was a positive correlation between depressive symptoms and LUTS severity (P<0.001). As compared to the mild LUTS group, the odds ratio (OR) of depression was 2.868 (95% confidence interval [CI], 1.293–6.362; P for trend<0.001) in the moderate LUTS group, and 4.133 (95% CI, 1.510–11.313; P for trend<0.001) in the severe LUTS group. In a model considering multiple variables such as age, education level, smoking, and exercise, the OR in the moderate LUTS group was 2.534 (1.125–5.708, 95% CI, P for trend=0.005), while that in the severe LUTS group was 3.910 (95% CI, 5.708–11.154; P for trend=0.005). In addition, depression was related to voiding symptoms. Conclusions: Men with severe LUTS are at higher risk of depression than those with less severe urinary symptoms. The severity of voiding symptoms worsens depression. More aggressive urological diagnosis and treatment is needed in patients with severe LUTS, due to the impact on depressive symptoms and QoL.

Urban Growth Politics and the Role of the State in the Process of Seoul Metropolitan Area's Overconcentration

정원식 경성대학교 사회과학연구소 2008 社會科學硏究 Vol.24 No.3

This study examines the political logic of centralized Korean state which led to the strong centralization of Korean urban/industrial growth in Seoul Metropolitan Area. The study argues that the over-concentration patterns have been shaped by the authoritarian Korean state’s developmentalist ideology and the civilian government’s neo-liberal policies, where pro-growth politics seem to be the main driving forces. The shape of Seoul as a primate city arose from the planned economy, such as the 5-year Economic Plans in Park's authoritarian government. Since the mid 1990s, the newly democratic governments have tried to make the growth-with-equity policy a priority. However, the government's new liberal market policies made the Capital Region more intensive in capital accumulation. It is argued that the urban policies of civilian government share many of the characteristics of early developmental strategies for urban and national economy, although the means and ends differ greatly. The Korean government thought that 'development can make further development.'
