본 연구는 스포츠이벤트 방송을 통한 주관 방송사의 시청률 상승효과를 분석하는데 그 목적이 있다. 시청률 분석을 통해 스포츠 프로그램 그 자체의 시청률 분석뿐만 아니라, 스포츠 프로그램이 인접 정규 프로그램의 시청률에 미치는 영향을 조사하였다. 이를 위해 특정 스포츠이벤트 방송(국가대표 축구 A매치)경기를 대상으로 직간접적인 시청률 상승효과가 채널간과 채널내에서 있었는지 알아보았다. 직접효과의 경우, 방송사가 스포츠이벤트를 편성함으로써 경쟁채널과 자사 정규프로그램에 비해서 월등히 유의미한 시청률 상승효과가 있음을 확인하였다. 간접효과의 경우, 사전전이효과인 유출효과는 채널간과 채널내에서 모두 나타나지 않았으며, 사후전이효과인 유입효과는 채널간과 채널내에서 유의미한 결과가 나왔다. 즉 인기 있는 스포츠이벤트를 방송함으로써 해당 시간뿐만 아니라 이후 시간대에서 시청률을 견인하는 효과가 있었으며, 이는 채널 자체의 인지도와 더불어 광고 시청률에도 일정부분 영향을 미친다고 추론할 수 있다. Television rating is a key factor for determining the unit price of the broadcasting advertisement. This study examined the influence of telecasting sports events (Korean National Football Teams` A-match games) on the television ratings of the sports program (direct effects) and the programs adjacent to the sporting events (indirect effects). The ratings of the sports programs and adjacent programs were compared to the ratings of the host broadcaster`s regular television programs, and to the competing broadcasters` television programs. The findings show that sporting events had higher television ratings as compared to the host broadcaster`s and the competing stations` regular television programs. In addition, it appeared that those programs aired after, but not before, the telecasts of sporting events had significantly higher ratings than the television ratings of the regular programs on both the host broadcaster`s and the competing stations` channels. Theoretical and practical implications are discussed.

본 연구는 2012 런던올림픽 방송방식을 방송사의 수익극대화 관점과 시청자의 수용자 복지 관점에서 이해할 수 있는 이론적 틀을 제시하였다. 우선 2012 런던올림픽의 공동중계 방식을 결정하는데 적용된 두 가지 기준으로 방송대상의 배분(종목배분 vs. 경기배분) 차원과 동시생중계 허용범위(동시생중계 허용 vs. 불허) 차원을 도출하고 각각의 기준에 대한 방송사별 선호방식과 이유를 방송사 관점에서 설명하였다. 한편 스포츠 방송의 공익성과 방송의 수용자 복지개념을 바탕으로 스포츠 방송고유의 수용자 복지 개념을 도출한 후 2012 런던 올림픽 방송에 적용된 두 가지 방송방식 결정차원이 스포츠 방송의 수용자복지에 미치는 영향을 설명하였다. 본 연구에서 제시된 이론적 틀은 향후 개최되는 국민관심 스포츠이벤트에 대한 바람직한 방송방식 결정에 적용할 수 있는 이론적 근거를 방송사 입장 뿐 아니라 수용자 복지 차원에서 제공하였다는 점에서 학술적의의는 물론 방송 실무자와 정책 입안자에게 시사하는 바가 크다. The 2012 London Olympic Games was jointly broadcast by the three major over-the-air broadcast stations in Korea. There appeared to be two primary dimensions that determined the specific methods to jointly broadcast the Olympic Games. The first dimension was how the objects of broadcast were assigned to the three broadcast channels (sport vs. game assignment). The second dimension was the degree to which simultaneous broadcast of the same game was allowed (not allowed vs. allowed). This study provides theoretical frameworks to understand how these two dimensions of joint broadcast methods would influence the profitabilities of broadcasters as well as the welfare of the television audiences. From the audience welfare perspective, the first dimension is associated with the quality of the broadcast program, whereas the second dimension is associated with program diversity issues. The study suggests that the appropriate method of joint broadcast should be determined based on considering the characteristics of the sport event, and the social consensus about the relative importance about various values associated with audience welfare.

Volatile organic compounds in buildings from finishing materials, adhesives, built-in furniture, etc. can cause headaches, atopic dermatitis, etc. for occupants in the buildings. To mitigate this, the Korean government has obligated to flush out the buildings after new construction and before occupancy since 2011. In this study, the current status of performing flush-out in multi-family residential buildings in Korea were analyzed, and its improvement would be proposed. At first, a questionnaire survey was conducted to figure out the current status of flush-out performances targeting a number of construction companies who have already constructed multi-family residential buildings with compliance of the obligation. Through the analysis of this survey, several conditions that need to be improved for flush-out were identified. Secondly, the identified conditions were evaluated in varying conditions using a simulation program to figure out an effective way of performing flush-out rather than as it is. As a result, a flush-out performance period with an appropriate supply air volume, and indoor temperature and humidity were identified to be improved through the survey, and it revealed through the simulation that the flush-out should be performed at least 14 days to reduce the indoor air pollution more than a half.

6-OHDA를 이용하여 실험적으로 유발한 파킨슨병 모델 동물을 대상으로 유전자 치료 목적으로 GDNF 유전자를 포함 하는 아데노바이러스 벡터(Ad-GDNF)를 주사하여 행동 변화와 줄무늬체와 흑색질의 tyrosine hydroxylase (TH) 면역반응양성의 도파민성 세포의 형태학적 변화를 연구하였다. 성숙한 수컷 Sprague-Dawley계 흰쥐의 줄무늬체에 6-OHDA를 주사하고, 1주 후에 apomorphine에 의한 회전 운동 양상 을 측정하여 분당 7회 이상 회전하는 동물은 파킨슨병 모델 동물에 해당하는 것으로 하였다. 이들 동물의 줄무늬체에 Ad-GDNF를 주사하고 1주 후에 apomorphine에 의한 행동 양상을 다시 측정하고, 이어서 심장 관류고정을 실시하여 형태 학적 변화를 관찰하였다. Ad-GDNF 대신에 LacZ 유전자를 포함하는 아데노바이러스 벡터(Ad-LacZ)를 주사한 것을 대조 군으로 이용하였다. 1. 파킨슨병 모델 동물의 줄무늬체에 Ad-GDNF를 주사한 동물에서 apomorphine에 의한 회전 운동 수가 유의하게 감소 하였다. 그러나 Ad-LacZ를 주사한 대조군에서는 회전 운동 수의 변화를 관찰할 수 없었다. 2. 회전 운동 수가 감소한 동물의 줄무늬체에 존재하는 TH 면역반응 양성의 축삭 종말은 대조군의 75% 수준으로 Ad- LacZ를 주사한 37%에 비하여 현저히 증가하여 TH 면역반응 양성 축삭종말의 퇴행성 변화가 방지되었다. 3. 흑색질의 TH 면역반응 양성 신경세포의 수는 Ad-GDNF를 주사한 군에서는 대조군의 82% 수준으로 Ad-LacZ를 주사한 군의 60% 수준에 비하여 유의하게 증가되어 있어서 6-OHDA에 의한 신경세포의 사멸이 방지되는 것을 알 수 있었다. 이상의 결과로 미루어 파킨슨병 모델 흰쥐의 줄무늬체에 Ad-GDNF를 한차례 주사하여 1주 후에 줄무늬체와 흑색질의 도파민성 세포의 사멸이 방지되는 것을 확인하였다. A recombinant adenoviral vector encoding human GDNF gene (Ad-GDNF) was developed to investigate the effect of GDNF gene in 6-OHDA-induced Parkinson’s disease rat. The changes of rotatory behavior and density of THimmunoreactive axon terminals and number of cell bodies were observed by the GDNF expression. Adult male Sprague-Dawley rats were used. Parkinson’s disease (PD) rat models were prepared by the injection of 6-OHDA into the striatum. After 1 week, the animals showing apomorphine-induced rotatory behavior above 7 turns/ min were defined as PD rat model. Ad-GDNF was injected into the striatum of animal model and tested the apomorphine- induced rotatory behavior at 1 week after injection. These animals were perfused with Zamboni fixative to investigate the morphological changes after rotatory behavior test. Instead of Ad-GDNF, Ad-LacZ injected PD rats were used as a control. The following results are obtained: 1. The apomorphine-induced rotational behavior was significantly reduced by the treatment of PD rat by the injection of Ad-GDNF. The Ad-LacZ injected PD rat showed no change in rotatory behavior. 2. The density of TH-ir axon terminals in the striatum was significantly increased by the Ad-GDNF injection (75% of normal side), but there was no change in the density by the Ad-LacZ injection (37% of normal side) compared to 6-OHDA lesioned striatum. This means the Ad-GDNF injection prevented the degenerative change of TH-ir axon terminals in the stritum of the PD rat. 3. The number of TH-ir cell body was significantly recovered by the Ad-GDNF (82% of normal side), but there was not recovered by the Ad-LacZ injection (60% of normal side) compared to 6-OHDA lesion. This means the retrogradely transported Ad-GDNF induced the TH expression in the dopaminergic neurons of the substantia nigra. Gene therapy with Ad-GDNF prevented the degeneration of dopaminergic neurons and axon terminals in the 6- OHDA-induced PD rat.
