Because many people suffer from physical and mental damage caused by the noise created by transportation infrastructure, including road traffic, rail, and aircraft, developed countries have conducted research on predicting and solving the impact to human health from being exposed to transportation noise. Therefore, this study suggests a fundamental plan to assess the health impact of transportation noise on the basis of domestic and foreign prediction results regarding the health impact of transportation noise. The domestic and foreign exposure-response expressions, including the noise index and the health impact indicator of annoyance and sleep disturbance, are compared, and it is found that domestic individuals show a more sensitive response to transportation noise. Based on domestic and foreign research, and a case study regarding the health impact of transportation noise, a fundamental plan to assess the health impact of transportation noise comprises the preparation of objective assessment standards through the improvement of exposure-response models, and the establishment of reduction measures which can improve the quality of the transportation noise environment.

This study suggests a strategy to provide effective mobile advertising marketed by identifying factors affecting the use and avoidance intention of mobile advertising on SNS. This article has three main findings. First, each factor of usefulness, novelty and irritation have a significant effect on satisfaction and usefulness, clutter and irritation factor have a significant effect on dissatisfaction. Second, satisfaction and dissatisfaction of mobile advertising exist at the same time, and it is confirmed that they are considered when consumers use mobile advertising. The third finding is that effective mobile advertising avoids the boredom of ads through moderating irritation and should be used in fresh form with more useful information than other ads' form. The result of this study should be an important criterion that mobile advertising providers make advertisements that consumers want in the future.

The purpose of this study is to reveal the quantitative dose-response relationship between the noise emitted in the platform of subway station and the public response. The noise measured in the platform of subway station was used for a jury test. In order to find the factors which influence annoyance response due to the platform noise, jurors were examined for the difference of the annoying response, interrelation of sound quality parameter and annoyance response. The platform noise level was 77.2$\sim$83.9 dBA and the most of passengers at the platform were highly annoyed. And screen door contributes to annoyance reduction of platform noise. The results from analyzing sound quality parameters shows that loudness and annoyance response have a high correlation coefficient.

This study examine the annoyance of transportation noise exposure and found the survey method about which noise induces more disturbance or annoyance when more than two kinds of noise exist. This study describes the noise annoyance survey performed in the vicinity of Sin-wol interchange. This residential area was exposed to aircraft noise and traffic noise simultaneously and aircraft noise exposure of this area is about 81 WECPNL, traffic noise exposure is about 81.2 dB(A) nearby road. Noise sources are grouped into three part, traffic noise, aircraft noise and community noise. The questionnaire includes how often, how loud each noise is heard. Also this deals with comparative annoyance reaction from specific noise sources such as aircraft or traffic and its disturbance of daily activities. Facade noise mapping are executed by using a commercial noise mapping software.

환경소음에 관한 연구는 주로 소음노출지역에 대한 소음 측정 및 사회적 조사(Social Survey)를 토대로 이루어 졌다. 이는 장기간 소음에 노출된 사람에 대한 소음평가의 수단뿐만 아니라 소음관련 법안 제정에 있어서 규제치를 결정하는 기준으로도 사용될 수 있다. 이에 반하여 본 논문에서는 소음에 대한 순간적인 반응 즉, 짧은 순간의 소음노출에 대한 주관적 반응을 알아보고자 하였으며, 방법적 측면(Methodology)에서의 제약으로 인하여 가상의 음 재현장치의 구성을 통하여 일반인을 대상으로 청감반응실험을 할 수밖에 없다. 먼저 항공기, 기차, 자동차 소음의 샘플을 녹음하여 일련의 신호처리 과정을 통하여 청감반응실험에 사용될 음원을 만들고, 청력검사를 통하여 청각에 이상이 있다고 판단되는 피검자의 데이터는 배제시킨 후 실험을 행하였다. 이러한 청감반응실험을 통하여 소음원의 종류, 성별, 연령, 소음 민감도 등에 따라 소음에 대한 성가심, 불쾌감의 정도는 다르게 나타남을 알 수 있었다.

Predicted noise level has been used to assess the annoyance response since noise map was generalized and being the normal method to assess the environmental noise. Unfortunately using predicted noise level to derive the annoyance prediction curve caused some problems. The data have to be grouped manually to use the annoyance prediction curve. The aim of this paper is to propose the method to handle the predicted noise level and the survey data for annoyance prediction curve. This paper used the percentage of persons annoyed(%A) and the percentage of persons highly annoyed as the descriptor of noise annoyance in a population. The logistic regression method was used for deriving annoyance prediction curve. It is concluded that the method of dichotomizing data and logistic regression was suitable to handle the predicted noise level and survey data.

The suggested method of previous Son's study dichotomized subjective response data to modeling noise exposure-response. The method used maximum liklihood estimation instead of least square estimation and the noise exposure-response curve of the study was logistic regression analysis result. The method was originated to modeling community response rate such as %HA or %A. It can be useful when the subjective response was investigated based on predicted noise level. It is difficult to measure the single source emitting noise such as railway because various traffic noise sources combined in our life. The suggested method was adopted to model in this study and railway noise-exposure response curves were modeled because the noise level of this area was predicted data. The data of this study was used by previous Ko's paper but he dealt the area as combined noise area and divided the data by dominant noise source. But this study used all data of this area because the annoyance response to railway noise was higher than other noise according to the result of correlation analysis. The trend of the %HA and %A prediction model to train noise of this study is almost same as the model based on measured noise of previous Lim's study although the investigated areas and methods were different.

In new housing demand, proportion of occupied multi-housing is 89.9% (statistics from 2013). In this way, with many generations living together, apartment noise disputes between the neighbors are continuously rising. The apartment noise problem in Korea is at a very serious level worldwide (about 88% of the population is experiencing stress due to apartment noise). On the other hand, the government has strengthened the regulations (such as the thickness of the floor and floor impact sound reduction performance, etc.) and promoted a resolution of its own for each multi-housing estates for mediating disputes on apartment noise. However, such physical regulations and passive management policies still presents a limit to the dispute mitigation of apartment noise. Also, in order to improve the quality of life in living spaces, policy on health effects of apartment noise should be provided. Therefore, we investigated a case study of the noise exposure-human body reaction to analyze the effect of noise on health. On the basis of this, the health effects according to the exposure period of apartment noise were considered.

Currently, dramatic change had led to the growth of the distribution environment and the retailer's distribution channel. This change had shifted the 'single channel' to 'multi channel', and from 'cross channel' to 'omni channel'. While fashion companies using omni channel are rapidly growing, few research regarding omni channel had been done in academic field. In this study, we examined the influence of omni channel characteristics on consumers' perceived risk as well as consumers' perceived risk toward attitude and intention to use omni channel. We surveyed 696 male and female respondents aged 20 to 40 who lived in Seoul and the metropolitan area. Using AMOS 20.0, factor analysis, reliability analysis, and structural equation model analysis were performed to verify the model of this study. The results were as follows. First, omni channel's instant connectivity, location-based provability, interactivity, and entertainment factors did not decrease impacts on the perceived risk related to privacy and annoyance. Second, omni channel's instant connectivity and entertainment did not increase effects on the perceived financial risk, and location-based provability and interactivity did not increase effect on perceived financial risk. Third, the perceived risk concerning omni channel did not decrease on consumer attitude toward omni channel. Fourth, consumer attitude toward omni channel influenced the intention to use omni channel significantly.
