미디어환경 변화와 광고시장 전망

남승용,노창희 한국통신학회 2011 정보와 통신 Vol.28 No.12

광고는 제조, 유통, 서비스 등의 산업에서 공급하는 재화등에 대한 정보를 확산시키고 소비자가 이의 재화에 대한 거래를 성립시키기 위한 수단이며 광고주가 미디어 기업 등에게 지불하는 광고비는 미디어 기업에서 양질의 콘텐츠를 제작·유통 할 수 있는 주요한 재원이다. 즉, 미디어는 광고주와 수용자가 공존하는 대표적인 양면시장이며 여기서 광고는 해당 시장을 유지하게 하는 중요한 수단이다. 이처럼 미디어 환경과 광고산업은 밀접한 관계를 가지고 있으며 이는 미디어 환경 및 광고 관련 규제에 국내 광고시장이 의존하고 있다는 것을 보여준다. 이에 본고에서는 최근 논의되고 있는 중간광고, 간접광고, 종합편성 채널 PP도입, 인터넷 광고 시장 현황 및 전망 등에 대하여 고찰하였다. 중간광고 등의 규제 완화는 국내 광고시장에 직접적으로 성장 가능성에 영향을 주고 있으나 이는 미디어 이용자의 이용행태를 고려하여야 할 것이다. 또한 종합편성 채널 PP도입은 해당 사업자가 제작비에 투자하는 정도에 따라 시청률에 영향을 주며 이의 효과로서 광고비가 증가 된다는 결론이 도출 되었다. 다만 지상파, 유료방송 고려시 순증효과와 대체효과가 공존하며 이의 결과 전반적으로 광고시장의 성장이 전망 되었다.

In this study, a conscious investigation and a walk status survey were conducted to establish countermeasures by analyzing the characteristics of the elderly walkers. First, the survey found that the elderly considered the age, which was one of the judgment criteria, for the elderly to be high than those for the nonaged. The elderly believed that there was no problem with their physical condition, and the risk of an accident was not high in their case. However, the percentage of elderly people who experienced pedestrian traffic accidents over the past five years is about three times higher, which presents the conclusion that there prevails a high risk of traffic accidents in the case of elderly pedestrians. Second, the analysis of the status of the elderly pedestrians crossing six types of crosswalks revealed that they had slower traversal speeds in comparison with the nonaged, and their reaction time after the green signal was also slower than the nonaged. There was no difference between the elderly and the nonaged in the case of left- and right-check identifications while crossing; the overall identification rate was very low.

In this study, the difference in gait patterns between the elderly and the non-aged was confirmed using a walking simulator. For the analysis, six variables, including the speed of the crossing, whether the vehicle was hit during the crossing, the direction of approach of the collision vehicle in the event of a collision, checking the left side of the crossing, and checking the right side of the crossing, were evaluated. It was observed from the analysis that the elderly pedestrians were slower in traversing than the non-aged, the cross-section failure rate was higher, and the vehicle crash rate was also higher during traversal. In addition, in the event of a collision, more number of crashes were caused by right-hand approach vehicles than by approach vehicles, and the left-hand confirmation rate dropped, but the right-hand confirmation rate was higher. These results suggest that the reduced physical abilities of elderly people due to aging can significantly increase the risk of pedestrian traffic accidents. Therefore, it is likely that the elderly will need to change their understanding and behavior of the vulnerabilities and characteristics of the elderly population as a result of this study.

This study considers safety facility, traffic intermittence, and traffic safety education in Korea. Importance of each driver’s traffic safety policy was analyzed. For this purpose, the weights of each policy were derived through consciousness surveys for general drivers, and weights of each item were evaluated by comparing an expert group with a general driver group. The weight of traffic enforcement was the highest for the expert group of the main category, was the lowest for the general driver group, and it was the highest for safety facility. Importance of facilities that can artificially inhibit or induce driver behavior was emphasized such that the weight of a general driver, an expert group, or a road safety facility was high in the middle class. In the case of traffic intermittence, there was a difference between the ratio of mechanical interdictions for general drivers and engineering intervention for experts. In middle classification, the weight of a general driver, expert group, or road safety facility was high, and facilities that artificially suppressed or induced driver behavior seemed important.

The purpose of this study is to investigate economic effect of job training in Korea. The data used in this study is 「 Korean Labor Panel Data」 in 1998~1999. The panel data includes recent individual data in Korea from 13,000 people(5,000 households). The economic effect of job training generally can be divided into two group such as micro-economics and macro-economics effects. From the micro-economic point of view, the level of employment and wage are increased. On the other hand, the national produtivity increase because of decreasing the level of unemployment. This study is to analyze the effect of job training on the level of employment and wage in the micro side. First of all, this study analyzes the determinants of job training experience for whom have special quality. Secondly, the determination of employment is analyzed by probit method. In addition, the wage equation is estimated by Heckman's two step method. Empirical results of this study are the same as the results from previous studies in terms of job training experience. The results confirm that probability of job training experience increases as the amount of human capital stocks increase. Besides, this study considers the effect of demographic variables such as sex, age, and the level of education on the level of employment. The employment effects are different from each group and statistically significant, These results can suggest some implications to policymakers. This study also analyzes the employment effect based on different programs such as government and private job training programs. According to the results of this study, private programs are more efficient than government programs in terms of employment rate. Finally, this study adopts Heckman's two step procedure to estimate wage equation in order to correct self-selection bias. The empirical results show that job training variable can affect the wage level and which support theoretical background of this study. In sum, the job training can affect the level of employment and wage positively.

본 연구에서는 날로 심각해지는 교통혼잡에 대한 대책마련의 일환으로 차량을 보유하는 요인은 무엇인가와 출근형태별로 어떤 교통수단을 선택하는가에 대하여 실제 정기적으로 통근을 하는 직장인을 대상으로 설문조사를 통해 분석하였다. 자가용 차량을 보유하는 요인으로는 연령, 소득 등이 유의한 결과를 나타냈고, 출근형태별 차량보유확률에서는 외곽에서 서울로 통근하는 경우와 외곽에서 외곽으로 통근하는 경우가 서울에서 서울로의 통근에 비해 차량을 보유 할 확률이 높았는데, 그 가운데서도 외곽에서 외곽으로 통근하는 경우가 차량보유 확률이 가장 높았다. 출근형태별 교통수단 선택 행태에 관한 다항 로짓분석 결과 서울에서 서울로의 출근의 경우 자가용보다는 대중교통을 이용할 확률이 높았다. 서울에서 외곽으로 출근하는 경우와 외곽에서 외곽으로 출근하는 경우에는 대중교통보다는 자가용을 선택할 확률이 높았으며, 외곽에서 서울로 출근하는 경우에는 자가용보다는 대중교통 선택확률이 높았으나 통계적 유의성은 없는 것으로 나타났다. This study explores the determinants of car ownership as part of preparing against traffic jams which is getting worse everyday and the mode choice classified by how people go to work. This is investigated by using a survey of office workers who go to work regularly. The reliable determinants of car ownership were age and income, etc. Also, regarding the probability of car ownership classified by how people go to work, the probability of people who go to work from outside of Seoul to inside of Seoul and from outside of Seoul to other places which are not Seoul were higher the one which people go to work from Seoul to Seoul. Especially, the probability of car ownership of people who went to work from outside of Seoul to other places was the highest. The type of travel mode choice is investigated by using multinomial logit regression which is commonly used for investigating discontinuous decision making. As a result, the probability of using public transport was higher than the one of using own cars for the people who went to work from Seoul to Seoul. Also, probabilities to choose own cars were higher than the one to choose public transport for the people who went to work from both Seoul and outside of Seoul to other places outside of Seoul. The probability of using public transport was higher than using own cars for the people who went to work from outside of Seoul to Seoul but the statistical significance was poor.

Purpose: This study aimed to investigate clinical outcomes of breast cancer patients who underwent mastectomy with or without immediate breast reconstruction. Methods: Of 1,847 patients undergoing total mastectomy, 371 (20.1%) underwent immediate reconstruction between January 2005 and December 2011. Clinicopathological characteristics and survival were compared by performing univariate and multivariate analysis. Results: The proportion of reconstruction had been gradually increasing since 2009. Reconstruction group showed younger age at diagnosis and lower cancer stages. Adjuvant chemotherapy and radiation therapy were more frequently administered in the mastectomy alone group. During a median follow-up period of 57 months, locoregional relapse-free survival (LRRFS) was similar regardless of type of surgery. However the reconstruction group showed a more favorable overall survival (OS). Multivariate analysis for LRRFS revealed no statistical significance but the OS was higher in the reconstruction group. In the mastectomy alone group, two-thirds died of breast cancer, while all patients in the reconstruction group died of breast cancer. Stage-matched breast cancer specific survival was similar between both groups. Conclusion: Immediate breast reconstruction is oncologically safe after mastectomy for breast cancer. Considering the quality of life, the patient should be preoperatively counseled by a multidisciplinary team regarding possible immediate reconstruction.
